    Management and outcome of muscle-invasive bladder cancer with clinical lymph node metastases. A nationwide population-based study in the bladder cancer data base Sweden (BladderBaSe)2019In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 53, no 5, p. 332-338Article in journal (Refereed)
    Abstract [en]

    Purpose: To investigate the clinical management and outcome of patients with muscle-invasive bladder cancer with clinical lymph node involvement, using longitudinal nationwide population-based data. Methods: In the Bladder Cancer Data Base Sweden (BladderBaSe), treatment and survival in patients with urinary bladder cancer clinical stage T2-T4 N + M0 diagnosed between 1997 and 2014 was investigated. Patients characteristics were studied in relation to TNM classification, curative or palliative treatment, cancer-specific (CSS) and overall survival (OS). Age at diagnosis was categorised as amp;lt;= 60, 61-70, 71-80 and amp;gt;80 years, and time periods were stratified as follows: 1997-2001, 2002-2005, 2006-2010 and 2011-2014. Results: There were 786 patients (72% males) with a median age of 71 years (interquartile range = 64-79 years). The proportion of patients with high comorbidity increased over time. Despite similar low comorbidity, curative treatment was given to 44% and to 70% of those in older (amp;gt;70 years) and younger age groups, respectively. Curative treatment decreased over time, but chemotherapy and cystectomy increased to 25% during the last time period. Patients with curative treatment had better survival compared to those with palliative treatment, both regarding CSS and OS in the whole cohort and in all age groups. Conclusions: The low proportion of older patients undergoing treatment with curative intent, despite no or limited comorbidity, indicates missed chances of treatment with curative intent. The reasons for an overall decrease in curative treatment over time need to be analysed and the challenge of coping with an increasing proportion of node-positive patients with clinically significant comorbidity needs to be met.

    Diagnostic value of repeated comprehensive investigation with CT urography and cystoscopy for recurrent macroscopic haematuria2024In: BJUI COMPASS, ISSN 2688-4526, Vol. 5, no 2, p. 253-260Article in journal (Refereed)
    Abstract [en]

    ObjectivesTo perform a descriptive analysis of a series of patients with recurrent macroscopic haematuria after a primary standard evaluation including computed tomography urography (CTU) and cystoscopy negative for urinary bladder cancer (UBC) and upper tract urothelial cancer (UTUC) and to identify potential factors associated with occurrence of recurrent macroscopic haematuria.MethodsAll patients older than 50 years who underwent urological investigation for macroscopic haematuria with both cystoscopy and CTU 2015-2017 were retrospectively reviewed. A descriptive analysis of the primary and later investigations for recurrent macroscopic haematuria was performed. To investigate the association between explanatory variables and the occurrence of recurrent macroscopic haematuria, a Poisson regression analysis was performed.ResultsA total of 1395 eligible individuals with primary standard investigation negative for UBC and UTUC were included. During a median follow-up of 6.2 (IQR 5.3-7) years, 248 (18%) patients had recurrent macroscopic haematuria, of whom six patients were diagnosed with UBC, two with prostate cancer, one with renal cell carcinoma and one had a suspected UTUC at the repeated investigation. Within 3 years, 148 patients (11%) experienced recurrent macroscopic haematuria, of whom two patients were diagnosed with low-grade UBC (TaG1-2), one with T2G3 UBC and one with low-risk prostate cancer. The presence of an indwelling catheter, use of antithrombotic medication, pathological findings at CTU or cystoscopy or history of pelvic radiotherapy were all statistically significant independent predictors for increased risk for recurrent macroscopic haematuria.ConclusionIn the case of recurrent macroscopic haematuria within 3 years of primary standard evaluation for urinary tract cancer, there was a low risk of later urological malignancies in patients initially negative for UBC and UTUC. Therefore, waiting 3 years before conducting another complete investigation in cases of recurrent macroscopic haematuria might be appropriate.

    Computed tomography urography with corticomedullary phase can exclude urinary bladder cancer with high accuracy2022In: BMC Urology, E-ISSN 1471-2490, Vol. 22, no 1, article id 60Article in journal (Refereed)
    Abstract [en]

    Background To evaluate the diagnostic accuracy of computed tomography-urography (CTU) to rule out urinary bladder cancer (UBC) and whether patients thereby could omit cystoscopy. Methods All patients evaluated for macroscopic hematuria with CTU with cortico-medullary phase (CMP) and cystoscopy at our institute between 1(st) November 2016 and 31(st) December 2019 were included. From this study cohort a study group consisting of all UBC patients and a control group of 113 patients randomly selected from all patients in the study cohort without UBC. Two radiologists blinded to all clinical data reviewed the CTUs independently. CTUs were categorized as positive, negative or indeterminate. Diagnostic accuracy and proportion of potential omittable cystoscopies were calculated for the study cohort by generalizing the results from the study group. Results The study cohort consisted of 2195 patients, 297 of which were in the study group (UBC group, n = 207 and control group, n = 90). Inter-rater reliability was high (kappa 0.84). Evaluation of CTUs showed that 174 patients were assesessed as positive (showing UBC), 46 patients as indeterminate (not showing UBC but with limited quality of CTU), and 77 patients as negative (not showing UBC with good quality of CTU). False negative rate was 0.07 (95%, CI 0.04-0.12), false positive rate was 0.01 (95% CI 0.0-0.07) and negative predictive value was 0.99 (95% CI 0.92-1.0). The area under the curve was 0.93 (95% CI 0.90-0.96). Only 2.9% (3/102) with high-risk tumors and 11% (12/105) with low- or intermediate-risk tumors had a false negative CTU. Cystoscopy could potentially have been omitted in 57% (1260/2195) of all evaluations. Conclusions CTU with CMP can exclude UBC with high accuracy. In case of negative CTU, it might be reasonable to omit cystoscopy, but future confirmative studies with possibly refined technique are needed.

    Standardized care pathways for patients with suspected urinary bladder cancer: the Swedish experience2022In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 56, no 3, p. 227-232Article in journal (Refereed)
    Abstract [en]

    Objectives To compare time intervals to diagnosis and treatment, tumor characteristics, and management in patients with primary urinary bladder cancer, diagnosed before and after the implementation of a standardized care pathway (SCP) in Sweden. Materials and methods Data from the Swedish National Register of Urinary Bladder Cancer was studied before (2011-2015) and after (2016-2019) SCP. Data about time from referral to transurethral resection of bladder tumor (TURBT), patients and tumor characteristics, and management were analyzed. Subgroup analyses were performed for cT1 and cT2-4 tumors. Results Out of 26,795 patients, median time to TURBT decreased from 37 to 27 days after the implementation of SCP. While the proportion of cT2-T4 tumors decreased slightly (22-21%, p < 0.001), this change was not stable over time and the proportions cN + and cM1 remained unchanged. In the subgroups with cT1 and cT2-4 tumors, the median time to TURBT decreased and the proportions of patients discussed at a multidisciplinary team conference (MDTC) increased after SCP. In neither of these subgroups was a change in the proportions of cN + and cM1 observed, while treatment according to guidelines increased after SCP in the cT1 group. Conclusion After the implementation of SCP, time from referral to TURBT decreased and the proportion of patients discussed at MDTC increased, although not at the levels recommended by guidelines. Thus, our findings point to the need for measures to increase adherence to SCP recommendations and to guidelines.

    Shortened time to diagnosis for patients suspected of urinary bladder cancer managed in a standardized care pathway was associated with an improvement in tumour characteristics2024In: BJUI COMPASS, ISSN 2688-4526, Vol. 5, p. 261-268Article in journal (Refereed)
    Abstract [en]

    Objectives To evaluate whether the implementation of standardized care pathway (SCP) for patients with suspected urinary bladder cancer (UBC) was associated with changes in tumour characteristics. Additionally, the study aims to explore whether there was a shift in the selection of patients prioritized for immediate evaluation regarding suspicion of UBC.Materials and Methods The study included all patients diagnosed with UBC in the NU Hospital Group between 2010 and 2019. To evaluate changes associated with SCP, patients were divided into two diagnostic time periods, either before (2010-2015) or during (2016-2019) the implementation of the SCP. To evaluate which patients were prioritized for prompt evaluation within 13 days, logistic regression analysis was performed on all patients before and during SCP.Results Median time to transurethral resection of the tumour in urinary bladder (TURBT) decreased from 29 days (interquartile range [IQR] 16-48) before SCP to 12 days (IQR 8-19) during SCP (p < 0.001) with a clear break from 2016. The proportion of cT2 + tumours decreased during SCP from 26% to 20% (p = 0.035). In addition, tumours detected during SCP were smaller (p = 0.023), but with more multiple lesions (p = 0.055) and G3 tumours (p = 0.007). During SCP, there was no statistically significant difference between the groups of patients with TURBT within or after 13 days. In contrast, before SCP, a majority of the patients treated within 13 days had advanced tumours and were admitted from the emergency ward.Conclusions The implementation of an SCP for suspected UBC was associated with improved tumour characteristics. Interestingly, during SCP, there were no substantial differences in patients' or tumours' characteristics among those who underwent TURBT within or after 13 days. This indicates that the 13-day timeframe for TURBT might be prolonged, especially in less urgent cases in order to facilitate a prioritization of more severe cases with treatable disease.

    PET/CT versus conventional CT for detection of lymph node metastases in patients with locally advanced bladder cancer.2015In: BMC Urology, E-ISSN 1471-2490, Vol. 15, no 1, p. 87-Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: We studied patients treated with radical cystectomy for locally advanced bladder cancer to compare the results of both preoperative positron emission tomography/computed tomography (PET/CT) and conventional CT with the findings of postoperative histopathological evaluation of lymph nodes.

    METHODS: Patients who had bladder cancer and were candidates for cystectomy underwent preoperative PET/CT using 18-fluorodeoxyglucose (FDG) and conventional CT. The results regarding lymph node involvement were independently evaluated by two experienced radiologists and were subsequently compared with histopathology results, the latter of which were reassessed by an experienced uropathologist (HO).

    RESULTS: There were 54 evaluable patients (mean age 68 years, 47 [85 %] males and 7 [15 %] females) with pT and pN status as follows: < pT2-14 (26 %), pT2-10 (18 %), and > pT2-30 (56 %); pN0 37 (69 %) and pN+ 17 (31 %). PET/CT showed positive lymph nodes in 12 patients (22 %), and 7 of those cases were confirmed by histopathology; the corresponding results for conventional CT were 11 (20 %) and 7 patients (13 %), respectively. PET/CT had 41 % sensitivity, 86 % specificity, 58 % PPV, and 76 % NPV, whereas the corresponding figures for conventional CT were 41 %, 89 %, 64 %, and 77 %. Additional analyses of the right and left side of the body or in specified anatomical regions gave similar results.

    CONCLUSIONS: In this study, PET/CT and conventional CT had similar low sensitivity in detecting and localizing regional lymph node metastasis in bladder cancer.

    M2-macrophage infiltration and macrophage traits of tumor cells in urinary bladder cancer2018In: Urologic Oncology, ISSN 1078-1439, E-ISSN 1873-2496, Vol. 36, no 4, article id 159.e19Article in journal (Refereed)
    Abstract [en]

    Background

    Tumor-associated macrophages (TAMs) constitute a subset of nonneoplastic cells in tumor stroma and influence cancer progression in solid tumors. The clinical significance of TAMs in urinary bladder cancer(UBC) is controversial.

    Methods

    We prospectively studied 103 patients with stage pT1–T4 UBC treated with cystectomy and pelvic lymph node dissection. Tumor sections were immunostained with M2-specific macrophage marker CD163 and proliferation marker Ki-67. The expression of these markers in cancer cells as well as macrophage infiltration (MI) in tumor stroma was analyzed in relation to clinical data and outcome.

    Results

    The mean rate of CD163 and Ki-67 expressed by cancer cells were 35% and 78%, respectively. With borderline significance, MI was associated with lower rate of lymph node metastasis (P = 0.06). CD163 expression in cancer cells was proportional to MI (P<0.014). Patients with CD163-positive tumors and strong MI had significantly longer cancer-specific survival (CSS) (76 months), compared to patient with CD163-positive tumors and weak MI (28 months) (P = 0.02).

    Conclusions

    M2-specific MI tends to be inversely correlated with LN metastasis and improved CSS in UBC. MI might have protective impact in CD163-positive tumors. Expression of CD163 in cancer cells is significantly correlated with MI and might have a tumor promoting impact.

    The expression profile of p14, p53 and p21 in tumour cells is associated with disease-specific survival and the outcome of postoperative chemotherapy treatment in muscle-invasive bladder cancer2018In: Urologic Oncology, ISSN 1078-1439, E-ISSN 1873-2496, Vol. 36, no 12, p. 530.e7-530.e18, article id 530.e7Article in journal (Refereed)
    Abstract [en]

    Purpose: We investigated the effects of alterations in the biological markers p14, p53, p21, and p16 in relation to tumour cell proliferation, T-category, N- category, lymphovascular invasion, and the ability to predict prognosis in patients with muscle-invasive bladder cancer (MIBC) treated with cystectomy and, if applicable, chemotherapy.

    Materials and methods: We prospectively studied patients with urinary bladder cancer pathological stage pT1 to pT4 treated with cystectomy, pelvic lymph node dissection and postoperative chemotherapy. Tissue microarrays from paraffin-embedded cystectomy tumour samples were examined for expression of immunostaining of p14, p53, p21, p16 and Ki-67 in relation to other clinical and pathological factors as well as cancer-specific survival.

    Results: The median age of the 110 patients was 70 years (range 51-87 years), and 85 (77%) were male. Pathological staging was pT1 to pT2 (organ-confined) in 28 (25%) patients and pT3 to pT4 (non-organ-confined) in 82 (75%) patients. Lymph node metastases were found in 47 patients (43%). P14 expression was more common in tumours with higher T-stages (P = 0.05). The expression of p14 in p53 negative tumours was associated with a significantly shorter survival time (P=0.003). Independently of p53 expression, p14 expression was associated with an impaired response to chemotherapy (P=0.001). The expression of p21 in p53 negative tumours was associated with significantly decrease levels of tumour cell proliferation detected as Ki-67 expression (P=0.03).

    Conclusions: The simultaneous expression of the senescence markers involved in the p53-pathway shows a more relevant correlation to the pathological outcome of MIBC than each protein separately. P14 expression in tumours with non-altered (p53-) tumours is associated with poor prognosis. P14 expression is associated with impaired response to chemotherapy. P21 expression is related to decreased tumour cell proliferation.

    Radio-guided sentinel lymph node detection and lymph node mapping in invasive urinary bladder cancer: a prospective clinical study.2017In: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 120, no 3, p. 329-336Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES: To investigate the possibility of detecting sentinel lymph nodes (SNs) in patients with urinary bladder cancer (BCa) intra-operatively and whether the histopathological status of the identified SNs reflected that of the lymphatic field.

    PATIENTS AND METHODS: We studied 103 patients with BCa pathological stage T1-T4 who were treated with cystectomy and pelvic lymph node (LN) dissection during 2005-2011 at the Department of Urology, Linköping University Hospital. Radioactive tracer Nanocoll 70 MBq and blue dye were injected into the bladder wall around the primary tumour before surgery. SNs were detected ex vivo during the operation with a handheld Geiger probe (Gamma Detection System; Neoprobe Corp., Dublin, OH, USA). All LNs were formalin-fixed, sectioned three times, mounted on slides and stained with haematoxylin and eosin. An experienced uropathologist evaluated the slides.

    RESULTS: The mean age of the patients was 69 years, and 80 (77%) were male. Pathological staging was T1-12 (12%), T2-20 (19%), T3-48 (47%) and T4-23 (22%). A mean (range) number of 31 (7-68) nodes per patient were examined, totalling 3 253 nodes. LN metastases were found in 41 patients (40%). SNs were detected in 83 of the 103 patients (80%). Sensitivity and specificity for detecting metastatic disease by SN biopsy (SNB) varied between LN stations, with average values of 67% and 90%, respectively. LN metastatic density (LNMD) had a significant prognostic impact; a value of ≥8% was significantly related to shorter survival. Lymphovascular invasion (LVI) occurred in 65% of patients (n = 67) and was significantly associated with shorter cancer-specific survival (P < 0.001).

    CONCLUSION: We conclude that SNB is not a reliable technique for peri-operative localization of LN metastases during cystectomy for BCa; however, LNMD has a significant prognostic value in BCa and may be useful in the clinical context and in BCa oncological and surgical research. LVI was also found to be a prognostic factor.

    The emerging role of cell cycle protein p53 expression by tumor cells and M2-macrophage infiltration in urinary bladder cancer2023In: Urologic Oncology, ISSN 1078-1439, E-ISSN 1873-2496, Vol. 41, no 3Article in journal (Refereed)
    Abstract [en]

    Purpose: To investigate the association between p53 expression in tumor cells and intratumoral macrophage infiltration in muscle-invasive urinary bladder cancer (MIBC) in relation to clinical and pathological variables and outcomes after radical cystectomy. Methods: Tumor specimens of the primary tumor from patients treated with radical cystectomy for MIBC were immunostained with the M2-macrophage-specific marker CD163 and the cell cycle protein p53. The expression of these markers was analyzed in relation to patients and tumor characteristics and outcome. Results: Out of 100 patients with urinary bladder cancer (UBC) pathological stage T1-4 N0-3 M0, 77% were men. The patients had a median age of 69 years and 80% had nonorgan-confined tumors (pT3-4). Lymph node metastasis was found in 42 (42%) of all patients. P53-positive expressions were found in 63 (63%) patients. Strong macrophage infiltration in the tumor microenvironment was shown in 74 (74%) patients. Combinations of CD163/p53 status were as follows: CD163+/p53+, 50%; CD163+/p53-, 24%; CD163-/p53+, 13%; and CD163-/p53-, 13%. Patients with CD163+/P53+ had higher proportions of organ-confined tumors. Conclusions: In the present series of patients with MIBC treated with cystectomy, we found that high CD163+ macrophage infiltration in the tumor micro-environment often was combined with p53+ cancer cells. This simultaneous expression of p53 by tumor cells and increased infiltration of M2-macrophages in the tumor microenvironment was associated with improved CSS, which might indicate a possible protective effect of M2 macrophages in p53+ tumors. Further investigations are needed to explore the biological relation between mutational burden and immune profile in MIBC. (c) 2022 Published by Elsevier Inc.

    Short term outcomes after robot assisted and open cystectomy- A nation-wide population-based study2023In: European Journal of Surgical Oncology, ISSN 0748-7983, E-ISSN 1532-2157, Vol. 49, no 4, p. 868-874Article in journal (Refereed)
    Abstract [en]

    Introduction: We aimed to compare short term outcomes after robot assisted radical cystectomy (RARC) and open radical cystectomy (ORC) for urinary bladder cancer in a large population.Materials and methods: We included all patients without distant metastases who underwent either RARC or ORC with ileal conduit between 2011 and 2019 registered in the Bladder cancer data Base Sweden (BladderBaSe) 2.0. Primary outcome was unplanned readmissions within 90 days, and secondary out-comes within 90 days of surgery were reoperations, Clavien 3-5 complications, total days alive and out of hospital, and mortality. The analysis was carried out using multivariate regression models.Results: Out of 2905 patients, 832 were operated with RARC and 2073 with ORC. Robotic procedures were to a larger extent performed during later years, at high volume centers (47% vs 17%), more often for organ-confined disease (82% vs. 72%) and more frequently in patients with high socioeconomic status (26% vs. 21%). Patients operated with RARC were more commonly readmitted (29% vs. 25%). In multi -variable analysis RARC was associated with decreased risk of Clavien 3-5 complications (OR 0.58, 95% CI 0.47-0.72), reoperations (OR 0.53, 95% CI 0.39-0.71) and had more days alive and out of hospital (mean difference 3.7 days, 95% CI 2.4-5.0).Conclusion: This study illustrates the "real-world" effects of a gradual and nation-wide introduction of RARC. Patients operated with RARC had fewer major complications and reoperations but were more frequently readmitted compared to ORC. The observed differences were largely due to more wound related complications among patients treated with ORC.(c) 2023 The Authors. Published by Elsevier Ltd.

    Bladder cancer recurrence in papillary urothelial neoplasm of low malignant potential (PUNLMP) compared to G1 WHO 1999: a population-based study2022In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 56, no 1, p. 14-18Article in journal (Refereed)
    Abstract [en]

    Objective Papillary urothelial neoplasm of low malignant potential (PUNLMP) and stage TaG1 non-muscle invasive bladder cancer (NMIBC) represent separate categories in current WHO 1999 grade definitions. Similarly, PUNLMP and Ta low-grade are separate entities in the WHO 2004/2016 grading system. However, this classification is currently questioned by reports showing a similar risk of recurrence and progression for both categories. Patients and methods In this population-based study, risk estimates were evaluated in patients diagnosed with PUNLMP (n = 135) or stage TaG1 (n = 2176) NMIBC 2004-2008 with 5-year follow-up registration in the nation-wide Bladder Cancer Data Base Sweden (BladderBaSe). The risk of recurrence was assessed using multivariable Cox regression with adjustment for multiple confounders (age, gender, marital status, comorbidity, educational level, and health care region). Results At five years, 28/135 (21%) patients with PUNLMP and 922/2176 (42%) with TaG1 had local recurrence. The corresponding progression rates were 0.7% (1/135) and 4.0% (86/2176), respectively. A higher relative risk of recurrence was detected in patients with TaG1 tumours compared to PUNLMP (Hazard Ratio 1.6, 95% CI 1.2-2.0) at 5-year follow-up, while progression events were too few to compare. Conclusions The difference in risk of recurrence between primary stage TaG1 and PUNLMP stands in contrast to the recently adapted notion that treatment and follow-up strategies can be merged into one low-risk group of NMIBC.

    A population-based study on the effect of a routine second-look resection on survival in primary stage T1 bladder cancer2021In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 55, no 2, p. 108-115Article in journal (Refereed)
    Abstract [en]

    Objective To assess the value of second-look resection (SLR) in stage T1 bladder cancer (BCa) with respect to progression-free survival (PFS), and also the secondary outcomes recurrence-free survival (RFS), bladder-cancer-specific survival (CSS), and cystectomy-free survival (CFS). Patients and methods The study included 2456 patients diagnosed with stage T1 BCa 2004-2009 with 5-yr follow-up registration in the nationwide Bladder Cancer Data Base Sweden (BladderBaSe). PFS, RFS, CSS, and CFS were evaluated in stage T1 BCa patients with or without routine SLR, using univariate and multivariable Cox regression with adjustment for multiple confounders (age, gender, tumour grade, intravesical treatment, hospital volume, comorbidity, and educational level). Results SLR was performed in 642 (26%) individuals, and more frequently on patients who were aged &lt; 75 yr, had grade 3 tumours, and had less comorbidity. There was no association between SLR and PFS (hazard ratio [HR] 1.1, confidence interval [CI] 0.85-1.3), RFS (HR 1.0, CI 0.90-1.2), CFS (HR 1.2, CI 0.95-1.5) or CSS (HR 1.1, CI 0.89-1.4). Conclusions We found similar survival outcomes in patients with and patients without SLR, but our study is likely affected by selection mechanisms. A randomised study defining the role of SLR in stage T1 BCa would be highly relevant to guide current praxis.

    Bladder health in patients treated with BCG instillations for T1G2-G3 bladder cancer - a follow-up five years after the start of treatment2018In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 52, no 5-6, p. 377-384Article in journal (Refereed)
    Abstract [en]

    Objective: Investigate symptoms and how they affect daily life in patients with Non-Muscle Invasive Bladder Cancer (NMIBC) treated with Bacillus Calmette-Guerin (BCG) instillations. Materials and methods: Patients treated with BCG were included. After an initial transurethral resection (TURB) followed by a second-look resection, the patients were given an induction course with BCG for 6 weeks followed by maintenance therapy for 2 years. The patients answered a questionnaire before, during and after the treatment. The questionnaire contained questions about specific symptoms combined with bother questions on how each symptom affected patients life. Results: In total, 113 of 116 patients responded to the first questionnaire. Thirty per cent of all patients were bothered by disease-specific symptoms before the start of BCG. Few patients reported fever, haematuria, illness or urinary tract symptoms. No difference in symptoms was found between patients with or without concomitant CIS (carcinoma in situ). Patients younger than 65 years of age reported a greater worry about the symptom burden in the future than those who were older. Patients younger than 65 years reported a decreased level of mental well-being. Conclusion: Patients with bladder cancer T1G2-G3 had disease-specific symptoms present already before the start of the BCG. The burden of symptoms was reduced over time and showed that the bladder might recover. BCG instillations had side-effects that negatively affected the patients well-being. It is important to record the patients baseline bladder and voiding status before as well as during the BCG-instillation period in order to understand symptoms caused by the treatment.

    Bacillus Calmette-Guerin Is Superior to a Combination of Epirubicin and Interferon-alpha 2b in the Intravesical Treatment of Patients with Stage T1 Urinary Bladder Cancer. A Prospective, Randomized, Nordic Study2010In: European Urology, ISSN 0302-2838, E-ISSN 1873-7560, Vol. 57, no 1, p. 25-31Article in journal (Refereed)
    Abstract [en]

    Background: Bacillus Calmette-Guerin (BCG) instillation is regarded as the most effective bladder-sparing treatment for patients with high-grade T1 tumours and carcinoma in situ (CIS). The major problem with this therapy is the side-effects, making maintenance therapy difficult, even impossible, in a proportion of patients. Thus, alternative schedules and drugs have been proposed. Objective: To compare BCG to the combination of epirubicin and interferon-alpha 2b as adjuvant therapy of T1 tumours. Design, setting, and participants: This is a Nordic multicenter, prospective, randomised trial in patients with primary T1 G2-G3 bladder cancer. Initial transurethral resection (TUR) was followed by a second-look resection. Patients were randomised to receive either regimen, given as induction for 6 wk followed by maintenance therapy for 2 yr. Measurements: The drugs were compared with respect to time to recurrence and progression. Also, side-effects were documented. Results and limitations: A total of 250 patients were randomised. At the primary end point, 62% were disease free in the combination arm as opposed to 73% in the BCG arm (p = 0.065). At 24 mo, there was a significant difference in favour of the BCG-treated patients (p = 0.012) regarding recurrence, although there was no difference regarding progression. The subgroup analysis showed that the superiority of BCG was mainly in those with concomitant CIS. In a multivariate analysis of association with recurrence/progression status, significant variables for outcome were type of drug, tumour size, multiplicity, status at second-look resection, and grade. A corresponding analysis was performed separately in the two treatment arms. Tumour size was the only significant variable for BCG-treated patients, while multiplicity, status at second-look resection, and grade were significant for patients treated with the combination. Conclusions: For prophylaxis of recurrence, BCG was more effective than the combination. There were no differences regarding progression and adverse events between the two treatments.

    Analysis of progression and survival after 10 years of a randomized prospective study comparing mitomycin-C and bacillus Calmette-Guérin in patients with high-risk bladder cancer2007In: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 99, no 4, p. 817-820Article in journal (Refereed)
    Abstract [en]

    OBJECTIVE: To report the 10-year follow-up of a study randomizing between instillations of bacillus Calmette-Guérin (BCG) and mitomycin-C (MMC) for treating high-risk and not muscle-invasive urinary bladder cancer to assess progression, the need for more aggressive treatment and survival (cancer-specific and overall), as many of the published studies comparing different treatments for disease that is not muscle-invasive have a short follow-up. PATIENTS AND METHODS: Between 1987 and 1992, 261 patients were included, they had frequently recurring Ta/T1G1-G2, T1G3 or primary Tis-dysplasia. The patients were randomized to treatment with either 40 mg of MMC or 120 mg of BCG (Danish strain 1331) given weekly for 6 weeks, then monthly up to a year and finally every third month for a further year. The 250 evaluable patients were followed using hospital files and national registers on causes of death. RESULTS: The median follow-up for survivors was 123 months. The disease progressed in 58 (23%) of the patients, 34 in the MMC group and 24 in the BCG group (P = 0.26). Of the 140 patients who died, 68 were in the BCG and 72 in the MMC group (log-rank P = 0.98), most (95, 68%) died from other causes. CONCLUSION: Based on the follow-up of the present patients it cannot be concluded that the drugs originally administered, MMC or BCG, differed in their effect on progression, need for subsequent treatment or survival. © 2007 The Authors.

    The value of bladder mapping and prostatic urethra biopsies for detection of carcinoma in situ (CIS)2012In: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 110, no 2B, p. E41-E45Article in journal (Refereed)
    Abstract [en]

    OBJECTIVES To assess the value of bladder mapping and prostatic urethra biopsies for detection of urothelial carcinoma in situ (CIS). CIS of the urinary bladder is a flat high-grade lesion of the mucosa associated with a significant risk of progression to muscle-invasive disease. CIS is difficult to identify on cystoscopy, and definite diagnosis requires histopathology. Traditionally, if CIS is suspected, multiple cold-cup biopsies are taken from the bladder mucosa, and resection biopsies are obtained from the prostatic urethra in males. This approach is often called bladder mapping (BMAP). The accuracy of BMAP as a diagnostic tool is not known. PATIENTS AND METHODS Male patients with bladder cancer scheduled for cystectomy underwent cold-cup bladder biopsies (sidewalls, posterior wall, dome, trigone), and resection biopsies were taken from the prostatic urethra. After cystectomy, the surgical specimen was investigated in a standardised manner and subsequently compared with the BMAP biopsies for the presence of CIS. RESULTS The histopathology reports of 162 patients were analysed. CIS was detected in 46% of the cystoprostatectomy specimens, and multiple (greater than= 2) CIS lesions were found in 30%. BMAP (cold-cup bladder biopsies + resection biopsies from the prostatic urethra) provided sensitivity of 51% for any CIS, and 55% for multiple CIS lesions. The cold-cup biopsies for CIS in the bladder mucosa showed sensitivity and specificity of 46% and 89%, respectively. CONCLUSION Traditional cold-cup biopsies are unreliable for detecting CIS in bladder mucosa and negative findings must be interpreted with caution.

    Survival after radiotherapy versus radical cystectomy for primary muscle-invasive bladder cancer: A Swedish nationwide population-based cohort study2019In: Cancer Medicine, E-ISSN 2045-7634, Vol. 8, no 5, p. 2196-2204Article in journal (Refereed)
    Abstract [en]

    Background Studies of survival comparing radical cystectomy (RC) and radiotherapy for muscle-invasive bladder cancer have provided inconsistent results and have methodological limitations. The aim of the study was to investigate risk of death after radiotherapy as compared to RC. Methods We selected patients with muscle-invasive urothelial carcinoma without distant metastases, treated with radiotherapy or RC from 1997 to 2014 in the Bladder Cancer Data Base Sweden (BladderBaSe) and estimated absolute and relative risk of bladder cancer death and all-cause death. In a group of patients, theoretically eligible for a trial comparing radiotherapy and RC, we calculated risk difference in an instrumental variable analysis. We have not investigated chemoradiotherapy as this treatment was not used in the study time period. Results The study included 3 309 patients, of those 17% were treated with radiotherapy and 83% with RC. Patients treated with radiotherapy were older, had more advanced comorbidity, and had a higher risk of death as compared to patients treated with RC (relative risks of 1.5-1.6). In the "trial population," all-cause death risk difference was 6 per 100 patients lower after radiotherapy at 5 years of follow-up, 95% confidence interval -41 to 29. Conclusion(s) Patient selection between the treatments make it difficult to evaluate results from conventionally adjusted and propensity-score matched survival analysis. When taking into account unmeasured confounding by instrumental variable analysis, no differences in survival was found between the treatments for a selected group of patients. Further clinical studies are needed to characterize this group of patients, which can serve as a basis for future comparison studies for treatment recommendations.

    5-Year Outcome of a Randomized Prospective Study Comparing bacillus Calmette-Guerin with Epirubicin and Interferon-alpha 2b in Patients with T1 Bladder Cancer2014In: Journal of Urology, ISSN 0022-5347, E-ISSN 1527-3792, Vol. 191, no 5, p. 1244-1249Article in journal (Refereed)
    Abstract [en]

    Purpose: In a multicenter, prospectively randomized study we evaluated the 5-year outcomes of bacillus Calmette-Guerin alone compared to a combination of epirubicin and interferon-alpha 2b in the treatment of patients with T1 bladder cancer. Materials and Methods: Transurethral resection was followed by a second resection and bladder mapping. Stratification was for grade and carcinoma in situ. Followup entailed regular cystoscopy and cytology during the first 5 years. The end points assessed in this analysis were recurrence-free survival, time to treatment failure and progression, cancer specific survival and prognostic factors. Results: The study recruited 250 eligible patients. The 5-year recurrence-free survival rate was 38% in the combination arm and 59% in the bacillus Calmette-Guerin arm (p = 0.001). The corresponding rates for the other end points were not significantly different, as free of progression 78% and 77%, treatment failure 75% and 75%, and cancer specific survival 90% and 92%, respectively. The type of treatment, tumor size and tumor status at second resection were independent variables associated with recurrence. Concomitant carcinoma in situ was not predictive of failure of bacillus Calmette-Guerin therapy. An independent factor for treatment failure was remaining T1 stage at second resection. Conclusions: Bacillus Calmette-Guerin was more effective than the tested combination therapy. The currently recommended management with second resection and 3-week maintenance bacillus Calmette-Guerin entails a low risk of cancer specific death. More aggressive treatment in patients with infiltrative tumors at second resection might improve these results. In particular, concomitant carcinoma in situ was not a predictive factor for poor outcome after bacillus Calmette-Guerin therapy.

    Emmprin expression predicts response and survival following cisplatin containing chemotherapy for bladder cancer: A validation study2015In: Journal of Urology, ISSN 0022-5347, E-ISSN 1527-3792, Vol. 194, no 6, p. 1575-1581Article in journal (Refereed)
    Abstract [en]

    Purpose Neoadjuvant chemotherapy before cystectomy is recommended. To our knowledge the subset of patients likely to benefit has not been identified. We validate emmprin and survivin as markers of chemotherapy response. Materials and Methods Tumor specimens were obtained before therapy from a total of 250 patients with T1-T4 bladder cancer enrolled in 2 randomized trials comparing neoadjuvant chemotherapy before cystectomy with a surgery only arm. Protein expression was determined by immunohistochemistry. Results Expression was categorized according to predefined cutoffs reported in the literature. Data were analyzed with the Kaplan-Meier method and Cox models. Patients in the chemotherapy cohort with negative emmprin expression had significantly higher down staging overall survival than those with positive expression (71% vs 38%, p <0.001). The values for cancer specific survival were 76% and 56%, respectively (p <0.027). In the cystectomy only cohort emmprin expression was not associated with overall survival (46% vs 35%, p = 0.23) or cancer specific survival (55% vs 51%, p = 0.64). Emmprin negative patients had an absolute risk reduction of 25% in overall survival (95% CI 11-40) and a number needed to treat of 4 (95% CI 2.5-9.3). Survivin expression was not useful as a biomarker in this study. Limitations were the retrospective design and heterogeneity coupled with the time difference between the trials. Conclusions Patients with emmprin negative tumors have a better response to neoadjuvant chemotherapy before cystectomy than those with positive expression. © 2015 American Urological Association Education and Research, Inc.

    Number of transurethral procedures after non-muscle-invasive bladder cancer and survival in causes other than bladder cancer2022In: PLOS ONE, E-ISSN 1932-6203, Vol. 17, no 9, article id e0274859Article in journal (Refereed)
    Abstract [en]

    Background Previous research has associated repeated transurethral procedures after a diagnosis of non-muscle invasive bladder cancer (NMIBC) with increased risk of death of causes other than bladder cancer. Aim We investigated the overall and disease-specific risk of death in patients with NMIBC compared to a background population sample. Methods We utilized the database BladderBaSe 2.0 containing tumor-specific, health-related and socio-demographic information for 38,547 patients with NMIBC not primarily treated with radical cystectomy and 192,733 individuals in a comparison cohort, matched on age, gender, and county of residence. The cohorts were compared using Kaplan-Meier curves and Hazard ratios (HR) from a Cox regression models. In the NMIBC cohort, we analyzed the association between number of transurethral procedures and death conditioned on surviving two or five years. Results Overall survival and survival from causes other than bladder cancer estimated with Kaplan-Meier curves was 9.3% (95% confidence interval (CI) (8.6%-10.0%)) and 1.4% (95% CI 0.7%-2.1%) lower respectively for the NMIBC cohort compared to the comparison cohort at ten years. In a Cox model adjusted for prognostic group, educational level and comorbidity, the HR was 1.03 (95% CI 1.01-1.05) for death from causes other than bladder cancer comparing the NMIBC cohort to the comparison cohort. Among the NMIBC patients, there was no discernible association between number of transurethral procedures and deaths of causes other than bladder cancer after adjustment. The number of procedures were, however, associated with risk of dying from bladder cancer HR 3.56 (95% CI 3.43-3.68) for four or more resections versus one within two years of follow-up. Conclusion The results indicate that repeated diagnostic or therapeutic transurethral procedures under follow-up do not increase of risk dying from causes other than bladder cancer. The modestly raised risk for NMIBC patients dying from causes other than bladder cancer is likely explained by residual confounding.

    Abstract [en]

    PurposeWe constructed Bladder Cancer Data Base Sweden (BladderBaSe) 2.0 to expand studies in BladderBaSe on incidence, treatment outcomes, side effects, survival and health economic aspects of men and women with cancer in the urinary bladder, upper tract urothelial carcinoma (UTUC) (renal pelvis and ureter) and urethral carcinoma.ParticipantsBladderBaSe 2.0 includes 53 298 patients with cancer in the urinary bladder, diagnosed from 1 January 1997 to 31 December 2019, and 961 patients with UTUC in the renal pelvis and 792 in the ureter, and 146 patients with urethral urothelial carcinoma, diagnosed from 1 January 2015 to 31 December 2019, and in total 275 816 participants in reference groups, free of cancer in the urinary tract, matched 1:5 on sex, age and county.Findings to dateTo date, 18 published studies based on data from the BladderBaSe have investigated calendar time trends in survival; impact of gender, socioeconomic factors, tumour aggressiveness and hospital volume for radical cystectomy on prognosis; survival after radical cystectomy compared with radical radiotherapy; risk factors for complications and side effects after radical cystectomy such as thromboembolism, strictures of ureteroenterostomies and incisional hernia.Future plansThe BladderBaSe initiators are currently investigating gender-dependent detection delays due to urinary tract infections; survival after non-muscle invasive bladder cancer with respect to the number of transurethral resections; short-term outcomes comparing open and robot-assisted radical cystectomy; studies on risk for intravesical recurrence after different diagnostic measures in UTUC, and suicide risk after bladder cancer diagnosis. The BladderBaSe project group is open for collaborations with national and international colleagues.

    Cohort profile: The Swedish National Register of Urinary Bladder Cancer (SNRUBC) and the Bladder Cancer Data Base Sweden (BladderBaSe)2017In: BMJ Open, E-ISSN 2044-6055, Vol. 7, no 9, article id e016606Article in journal (Refereed)
    Abstract [en]

    Purpose To monitor the quality of bladder cancer care, the Swedish National Register of Urinary Bladder Cancer (SNRUBC) was initiated in 1997. During 2015, in order to study trends in incidence, effects of treatment and survival of men and women with bladder cancer, we linked the SNRUBC to other national healthcare and demographic registers and constructed the Bladder Cancer Data Base Sweden (BladderBaSe). Participants The SNRUBC is a nationwide register with detailed information on 97% of bladder cancer cases in Sweden as compared with the Swedish Cancer Register. Participants in the SNRUBC have registered data on tumour characteristics at diagnosis, and for 98% of these treatment data have been captured. From 2009, the SNRUBC holds data on 88% of eligible participants for follow-up 5 years after diagnosis of non-muscle invasive bladder cancer, and from 2011, data on surgery details and complications for 85% of participants treated with radical cystectomy. The BladderBaSe includes all data in the SNRUBC from 1997 to 2014, and additional covariates and follow-up data from linked national register sources on comorbidity, socioeconomic factors, detailed information on readmissions and treatment side effects, and causes of death. Findings to date Studies based on data in the SNRUBC have shown inequalities in survival and treatment indication by gender, regions and hospital volume. The BladderBaSe includes 38 658 participants registered in SNRUBC with bladder cancer diagnosed from 1 January 1997 to 31 December 2014. The BladderBaSe initiators are currently in collaboration with researchers from the SNRUBC investigating different aspects of bladder cancer survival. Future plans The SNRUBC and the BladderBaSe project are open for collaborations with national and international research teams. Collaborators can submit proposals for studies and study files can be uploaded to servers for remote access and analysis. For more information, please contact the corresponding author.

    Urinary diversion after cystectomy for bladder cancer: A population-based study in Sweden2010In: SCANDINAVIAN JOURNAL OF UROLOGY AND NEPHROLOGY, ISSN 0036-5599, Vol. 44, no 2, p. 69-75Article in journal (Refereed)
    Abstract [en]

    Objective. To investigate the type of urinary diversion performed after cystectomy in patients with muscle-invasive bladder cancer in Sweden, using data from a population-based national register. Material and methods. Since 1997, the Swedish Bladder Cancer Register has included more than 90% of all patients with newly diagnosed bladder cancer. The different types of urinary diversion performed in 1997-2003 were analysed, comparing non-continent diversion (ileal conduit) with continent reconstruction (bladder substitution or continent cutaneous diversion). Results. During the study period, 3463 patients were registered with clinical T2-T4 non-metastatic bladder cancer. Cystectomy was performed in 1141 patients with ileal conduit in 732 (64%) and continent reconstruction in 409 (36%). Ileal conduit was used more frequently in females than males (p = 0.019), in patients older than 75 years (p andlt; 0.00001), and in those with less favourable TNM classification. Continent reconstruction was done more often at university hospitals than at county hospitals (p andlt; 0.00001), but rarely in the northern and western healthcare regions compared with other regions (p andlt; 0.00001). Nationwide, the proportion of registered continent reconstructions decreased, although the absolute number was relatively stable (50-60 per year). Conclusions. Continent reconstruction after cystectomy for muscle-invasive bladder cancer is performed more often in some healthcare regions and in patients at university hospitals than in county hospitals, indicating a substantial provider influence on the choice of urinary diversion. Over time, the proportion of these procedures has decreased, while the absolute number has remained low and stable; therefore, concentration in high-volume hospitals specialized in bladder cancer and continent reconstruction seems appropriate.

    A population-based study of patterns of care for muscle-invasive bladder cancer in Sweden2009In: SCANDINAVIAN JOURNAL OF UROLOGY AND NEPHROLOGY, ISSN 0036-5599, Vol. 43, no 4, p. 271-276Article in journal (Refereed)
    Abstract [en]

    Objective. To analyse the management of muscle-invasive bladder cancer in a population-based national register, and specifically to investigate the role of curative therapy (i.e. cystectomy or radiotherapy) in relation to patient, tumour and hospital characteristics. Material and methods. The Swedish Bladder Cancer Register covers more than 90% of all patients in the country who have been diagnosed with such disease since 1997. Results from 1997-2003 were analysed regarding curative-intent treatment given within 3-6 months of diagnosis of muscle-invasive bladder cancer. Results. In total, 3463 patients with clinical T2-T4 bladder cancer were included in the analysis. Of those patients, 1426 (41%) received curative-intent treatment in the form of radiotherapy (285, 20%) or cystectomy (1141, 80%). Male gender, age 76 years, favourable TNM category and registration at a high-volume hospital were associated with such treatment. Curative-intent treatment was given to significantly more patients registered at high-volume hospitals (1003/2227, 45%) than at low-volume hospitals (423/1235, 34%) (2=37.7, p0.00001). Cystectomy was performed more often in those registered at high-volume than at low-volume hospitals (826/2227, 37%, and 316/1235, 26%, respectively, 2=47.3, p0.00001). Conclusions. Lower rates of curative-intent treatment were found in patients registered at low-volume than at high-volume facilities, and the same was seen when comparing females with males, and patients aged 76-80 years with younger patients. Since many of these bladder cancer patients were registered at and eventually treated at hospitals handling fewer than 10 such cases annually, it seems desirable to concentrate treatment of this disease at more specialized centres.

    Management and outcome of TaG3 tumours of the urinary bladder in the nationwide, population-based bladder cancer database Sweden (BladderBaSe)In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813Article in journal (Refereed)
    Abstract [en]

    Purpose: To investigate the management of TaG3 tumours of the urinary bladder using nationwide population-based data in relation to the prevailing guidelines, patients characteristics, and outcome. Materials and methods: The Bladder Cancer Data Base Sweden (BladderBaSe), including data from the Swedish National Register for Urinary Bladder Cancer (SNRUBC), was used to study all patients with TaG3 bladder cancer diagnosed from 2008 to 2014. Patients were divided into the following management groups: (1) transurethral resection (TUR) only, (2) TUR and intravesical instillation therapy (IVIT), (3) TUR and second-look resection (SLR), and (4) TUR with both SLR and IVIT. Patient and tumour characteristics and outcome were studied. Results: There were 831 patients (83% males) with a median age of 74 years. SLR was performed more often on younger patients, on men, and less often in the Western and Uppsala/orebro Healthcare regions. IVIT was performed more often with younger patients, with men, in the Western Healthcare region, and less often in the Uppsala/orebro Healthcare region. Death from bladder cancer occurred in 6% of cases within a median of 29 months (0-84 months) and was lower in the TUR/IVIT and TUR/SLR/IVIT groups compared to the other two groups. Conclusion: In the present study, there was, according to the prevailing treatment guidelines, an under-treatment with SLR for older patients, women, and in some healthcare regions and, similarly, there was an under-treatment with IVIT for older patients. Cancer-specific survival and relative survival were lower in the TUR only group compared to the TUR/IVIT and TUR/SLR/IVIT groups.

    Thromboembolism in Muscle-Invasive Bladder Cancer. A Population-based Nationwide Study2021In: BLADDER CANCER, ISSN 2352-3727, Vol. 7, no 2, p. 161-171Article in journal (Refereed)
    Abstract [en]

    BACKGROUND: Routine VTE prophylaxis within 30 days of radical cystectomy (RC) for urinary bladder cancer (UBC) is used to protect from venous thromboembolism (VTE). However, randomized studies and nationwide population-based studies are lacking. OBJECTIVE: To study VTE and risk factors for VTE in muscle-invasive UBC in a nationwide population-based series, with a focus on the association with RC with and without chemotherapy. MATERIALS AND METHODS: We studied all patients with clinical stage T2-T4 UBC diagnosed 1997 to 2014 in the Bladder Cancer Data Base Sweden (BladderBaSe). Previous VTE events and risk factors for VTE were registered from 1987. Cox regression analyses and Kaplan-Meier curves were performed to study risk factors for VTE and cumulative incidence of VTE. RESULTS: In 9720 patients (71% males) with a median age of 74 years 546 (5.6%) had VTE after diagnosis. In Cox analyses controlling for patients and tumour characteristics, and risk factors for VTE, VTE after diagnosis and first treatment date were associated with chemotherapy with or without RC. Cumulative incidence of VTE increased during 24 months after diagnosis and first treatment date. VTE were less common in patients with previous cardiovascular disease. CONCLUSION: VTE was commonly observed after 30 days from diagnosis and from first treatment date in patients with T2-T4 UBC, particularly after chemotherapy. The findings suggest that long-term intervention studies of benefit and possible harms of VTE prophylaxis after UBC should be undertaken.

    Swedish National Registry of Urinary Bladder Cancer: No difference in relative survival over time despite more aggressive treatment2016In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 50, no 1, p. 14-20Article in journal (Refereed)
    Abstract [en]

    Objective. The aim of this study was to use the Swedish National Registry of Urinary Bladder Cancer (SNRUBC) to investigate changes in patient and tumour characteristics, management and survival in bladder cancer cases over a period of 15 years. Materials and methods. All patients with newly detected bladder cancer reported to the SNRUBC during 1997-2011 were included in the study. The cohort was divided into three groups, each representing 5 years of the 15 year study period. Results. The study included 31,266 patients (74% men, 26% women) with a mean age of 72 years. Mean age was 71.7 years in the first subperiod (1997-2001) and 72.5 years in the last subperiod (2007-2011). Clinical T categorization changed from the first to the last subperiod: Ta from 45% to 48%, T1 from 21.6% to 22.4%, and T2-T4 from 27% to 25%. Also from the first to the last subperiod, intravesical treatment after transurethral resection for T1G2 and T1G3 tumours increased from 15% to 40% and from 30% to 50%, respectively, and cystectomy for T2-T4 tumours increased from 30% to 40%. No differences between the analysed subperiods were found regarding relative survival in patients with T1 or T2-T4 tumours, or in the whole cohort. Conclusions. This investigation based on a national bladder cancer registry showed that the age of the patients at diagnosis increased, and the proportion of muscle-invasive tumours decreased. The treatment of all tumour stages became more aggressive but relative survival showed no statistically significant change over time.

    Bladder cancer grading using the four-tier combination of the World Health Organization (WHO) 1973 and WHO 2004 classifications2023In: BJU International, ISSN 1464-4096, E-ISSN 1464-410XArticle in journal (Refereed)
    Abstract [en]

    ObjectiveTo investigate the impact of grading in urothelial bladder cancer (UBC) stages Ta and T1, comparing the World Health Organization (WHO) grading classifications of 1973 (WHO73) and 2004 (WHO04) and a combination of these (WHO73/04).Patients and MethodsAll patients with primary Ta and T1 UBC in the ostergotland region, Sweden, between 1992 and 2007 were included. From 1992, we introduced a new programme for management and follow-up of UBC, including prospectively performed registration of all patients, a systematic description of the location and size of all tumours, primary resection and intravesical treatment in the case of recurrence. All tumour specimens were retrospectively reviewed in 2008 and graded according to the WHO73 and WHO04. A combination of WHO73/04, Grade 1 (G1), Grade 2 low grade (G2LG), Grade 2 high grade (G2HG) and Grade 3 (G3) was analysed in relation to clinical variables and outcomes.ResultsThere were 769 patients with a median age of 72 years and a median follow-up duration of 74 months. Recurrence was noted in 484 patients (63%) and progression in 80 patients (10%). Recurrence was more common in multiple tumours, larger tumours and in tumours of higher grade (G2LG, G2HG and G3). Progression was more common in tumours classified as larger, T1 and G2HG and G3. Notably, in tumours classified as G2HG, recurrence and progression were more common than in the G2LG group. Harrells concordance index for the WHO73/04 was higher for recurrence and progression than in the WHO73 or WHO04.ConclusionIn the four-tier combined WHO73/04 for urothelial cancer, we observed two G2 sub-groups, G2HG and G2LG. There was a better outcome in the latter group, and the importance of G1 and G3 tumours could be fully evaluated. The WHO73/04 had greater accuracy for recurrence and progression than either the WHO73 or WHO04.

    Modulation of the inflammatory response after sclerotherapy for hydrocoele/spermatocoele2019In: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 123, no 5A, p. E63-E68Article in journal (Refereed)
    Abstract [en]

    Objective

    To investigate the modulation of the inflammatory response after sclerotherapy for hydrocoele/spermatocoele.

    Patients and Methods

    All patients with hydrocoele or spermatocoele presenting at the Department of Urology, University Hospital, Linköping, Sweden, from 2006 to 2012, were included in this prospective observational study of sclerotherapy for hydrocoele/spermatocoele using polidocanol as a sclerosing agent and adjuvant antibiotic and anti‐inflammatory medication (AAAM) for modulation of the inflammatory response. Patients were clinically evaluated within 24–48 h after a complication or adverse event possibly related to sclerotherapy. Evaluation of cure was scheduled after 3 months and re‐treatment, if necessary was carried out in the same manner as the first treatment. Groups of patients were compared using the chi‐squared test and logistic regression analysis.

    Results

    From a total of 191 patients, AAAM was given to 126, of whom 5% had subclinical epididymitis/swelling (SES) compared to 26% of the patients without AAAM (P < 0.001). No other complication was observed. The rate of cure for the whole group of patients was 93% after one or two treatments and significantly higher in the group with AAAM than in the group without AAAM (96% vs 88%, P = 0.03).

    Conclusions

    Modulation of the inflammatory response after sclerotherapy resulted in a lower incidence of SES and an increased cure rate.

    A Randomized Trial Comparing 2 Doses of Polidocanol Sclerotherapy for Hydrocele or Spermatocele2011In: Journal of Urology, ISSN 0022-5347, E-ISSN 1527-3792, Vol. 186, no 4, p. 1319-1323Article in journal (Refereed)
    Abstract [en]

    Purpose: Polidocanol sclerotherapy for hydrocele or spermatocele combines high efficiency with low morbidity, but the optimal dose is not known. We compared the efficacy and morbidity of 2 or 4 ml polidocanol sclerotherapy for hydrocele or spermatocele. less thanbrgreater than less thanbrgreater thanMaterials and Methods: From 1993 to 2005 a double-blind randomized clinical trial was conducted using 2 or 4 ml polidocanol (30 mg/ml) for sclerotherapy of hydrocele/spermatocele in 224 evaluable patients at 3 university hospitals. Fluid was evacuated and 2 or 4 ml polidocanol was administered by a nurse, with the amount injected concealed from others present. At 3-month followup morbidity was ascertained using a questionnaire completed by the patients. Fluid recurrence was determined clinically and generally re-treated. less thanbrgreater than less thanbrgreater thanResults: After the first treatment, cure was observed in 59% and 47% in the 4 and the 2 ml group, respectively (p = 0.04). More patients in the 4 ml group had complications (31% vs 18%, p = 0.04). Complications were mostly of low or moderate intensity and seldom required medication. After 1 to 4 treatments 200 of 224 patients (89%) were cured and another 10 (5%) had small amounts of residual fluid, with no difference between the groups. Of the patients with hydroceles/spermatoceles larger than 175 ml, 58% and 34% were cured after the first treatment in the 4 and 2 ml groups, respectively (p = 0.012), with no differences in complications between the groups. less thanbrgreater than less thanbrgreater thanConclusions: Polidocanol sclerotherapy was effective for the treatment of hydrocele or spermatocele in our patients, with 94% satisfactory results after 1 to 4 treatments. A dose of 4 ml was superior to 2 ml, particularly for larger hydroceles/spermatoceles.

    Telomerase reverse transcriptase mutation and the p53 pathway in T1 urinary bladder cancer2022In: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 129, no 5, p. 601-609Article in journal (Refereed)
    Abstract [en]

    Objective To study the telomerase reverse transcriptase (TERT) mutation and the p53 pathway in T1 urinary bladder cancer (UBC). Materials and Methods This prospectively performed population-based study included all patients in the Southeast Healthcare Region in Sweden with T1 UBC registered in the period 1992-2001, inclusive. Given that p53 and TERT are important factors for tumour proliferation, although their interrelationships are unknown, we assessed both the TERT and the p53 mutations. Furthermore, we conducted a p53 immunohistochemistry (IHC) analysis using two thresholds for p53 positivity: 10% of tumour cells and 50% of tumour cells (p53 IHC50%). Cox proportional hazards analysis and Kaplan-Meier curves were used to study time to tumour progression. Results Out of 158 patients, we observed the TERT mutation in 74 (47%), the p53 mutation in 48 (30%), and p53 IHC50% positivity in 72 patients (46%). The TERT mutation was more common in p53 mutation-positive patients (P = 0.009), and the latter group also had more patients with p53 IHC50%-positive tumour cells (P = 0.02). In the TERT mutation-negative tumours a p53-positive mutation was associated with a shorter time to progression (P = 0.03) compared to patients with p53-negative mutation. In contrast, in tumours with both TERT mutation positivity and p53 mutation positivity, a longer time to progression was observed in the group with p53 IHC50% positivity compared to the group with p53 IHC50%-negative tumours. Conclusions In stage T1 UBC, the combination of the TERT mutation and the p53 mutation was associated with tumour progression. A protective effect of the TERT promotor mutation against tumour progression induced by the p53 mutation and subsequent p53 accumulation in tumour cells might be possible, but further investigations are necessary.

    Results of second-look resection after primary resection of T1 tumour of the urinary bladder2005In: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 39, no 3, p. 206-210Article in journal (Refereed)
    Abstract [en]

    Objective. To study residual tumours at second-look resection in patients resected 4-8 weeks earlier for T1 tumours of the urinary bladder. Material and methods. All patients randomized in the ongoing Nordic T1G2-G3 Bladder Sparing Study with monitored data available were included in the study. Data on residual tumours at second-look resection were compared to basic patient and tumour characteristics. Results. There were 72 patients (56%) without and 57 with residual exophytic tumours. In the former group, 20 patients (28%) had carcinoma in situ, compared to 19 (33%) in the latter group. Potentially dangerous tumours (either carcinoma in situ, T1 or Ta grade 3) were observed in 55 patients (43%). Multiple tumours at primary resection were more prone to residual tumour at second-look resection than single tumours. No other tumour or patient characteristics could predict the occurrence of a residual tumour. Conclusions. Residual tumours are frequently observed at second-look resection 4-8 weeks after primary resection of T1 tumours. The majority of residual tumours detected at this stage are potentially dangerous, therefore, early second-look resection followed by intravesical instillation therapy is mandatory in patients with T1 tumours of the urinary bladder. © 2005 Taylor & Francis.

    Risk factors for local recurrence in patients with pTa/pT1 urinary bladder cancer2008In: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 42, no 5, p. 417-421Article in journal (Refereed)
    Abstract [en]

    Objective. This study evaluated risk factors for local tumour recurrence, defined as recurrence at the same location in the bladder within 18 months after primary resection in patients with newly diagnosed pTa or pT1 bladder cancer. Patients and methods. The study included 472 patients with newly diagnosed pTa/T1 bladder cancer between 1992 and 2001. The patients were followed prospectively in accordance with a control programme and possible risk factors for tumour recurrence were registered. Results. Local tumour recurrence was observed in 164 (35%) patients, another 117 (25%) patients had recurrence at other locations in the bladder (non-local recurrence) and 191 (40%) had no recurrence at all. Tumour size and multiple tumours were significantly associated with a higher risk for developing local recurrence as opposed to non-local recurrence. Tumour category was of borderline statistical significance. Gender and tumour grade were not found to be risk factors for developing local recurrence. Conclusion. Tumour size and multiplicity are risk factors for development of recurrence at the same location in the bladder as the primary tumour. Local tumour recurrence may be a result of non-radical primary transurethral resection. One may consider recommending standard re-resection within 6-8 weeks in patients with tumours >3 cm or those with multiple primary tumours. © 2008 Informa UK Ltd.

    Intravesical instillations and cancer-specific survival in patients with primary carcinoma in situ of the urinary bladder2017In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 51, no 2, p. 124-129Article in journal (Refereed)
    Abstract [en]

    Objective: The aim of this study was to evaluate the use of intravesical treatment and cancer-specific survival of patients with primary carcinoma in situ (CIS). Materials and methods: Data acquisition was based on the Swedish National Registry of Urinary Bladder Cancer by selecting all patients with primary CIS. The analysis covered gender, age, hospital type and hospital volume. Intravesical treatment and death due to bladder cancer were evaluated by multivariate logistic regression and multivariate Cox analysis, respectively. Results: The study included 1041 patients (median age at diagnosis 72 years) with a median follow-up of 65 months. Intravesical instillation therapy was given to 745 patients (72%), and 138 (13%) died from bladder cancer during the observation period. Male gender [odds ratio (OR) = 1.56, 95% confidence interval (CI) 1.13-2.17] and treatment at county (OR = 1.65, 95% CI 1.17-2.33), university (OR =2.12, 95% CI 1.48-3.03) or high-volume (OR= 1.92, 95% CI 1.34-2.75) hospitals were significantly associated with higher odds of intravesical instillations. The age category amp;gt;80 years had a significantly lower chance of receiving intravesical therapy (OR = 0.44, 95% CI 0.26-0.74) and a significantly higher risk of dying from bladder cancer (hazard ratio = 3.03, 95% CI 1.71-5.35). Conclusion: Significantly more frequent use of intravesical treatment of primary CIS was found for males and for patients treated at county, university and high-volume hospitals. Age amp;gt;80 years was significantly related to less intravesical treatment and poorer cancer-specific survival.

Recurrence was observed in 478 patients (62%) and progression in 71 (9%). High-grade malignant bladder wash cytology was predictive for recurrence and progression (P andlt; .001 and P = .036, respectively). Other factors affecting recurrence were missing bladder wash cytology data, tumors size 16-30 mm and andgt;30 mm, Stage T1 tumor category, and multiplicity (P = .008, P = .006, P andlt; .001, P = .002, and P andlt; .001, respectively). Progression was also associated with T1 tumor category, local recurrence, and primary concomitant carcinoma in situ (P andlt; .001, P andlt; .001, and P = .024, respectively). less thanbrgreater than less thanbrgreater thanCONCLUSION High-grade malignant bladder wash cytology at the primary diagnosis was predictive for recurrence and progression. This could be taken into account in designing future follow-up schedules.

    Impact of surgical experience on recurrence and progression after transurethral resection of bladder tumour in non-muscle-invasive bladder cancer2014In: SCANDINAVIAN JOURNAL OF UROLOGY, ISSN 2168-1805, Vol. 48, no 3, p. 276-283Article in journal (Refereed)
    Abstract [en]

    Introduction: To evaluate the impact of experience in transurethral resection of bladder tumor (TUR-BT) on recurrence and progression in primary Ta/T1 urinary bladder cancer.

    Methods: Clinical and pathological characteristics of patients with primary Ta/T1 urinary bladder cancer were recorded prospectively from 1992 to 2007 inclusive. Data on surgeons’ experience were categorized as follows: (a) experience by training status (residents or specialists); (b) number of TUR-BTs performed by each surgeon during the registration period, with cut-off levels at > 100, > 150, > 200, > median, and > third quartile of surgical volume; (c) lifetime high-volume surgeons (> 100 TUR-BTs). Hazard ratios (HRs) were estimated using Cox regression with 95% confidence intervals (CIs) in both univariate and multivariate analysis.

    Results: The analysis included 768 evaluable patients with a median follow-up of 60 months. Recurrence was observed in 478 patients (62%) and progression in 71 (9%). Surgery was performed by residents in 100 cases and specialists in 668, with recurrence in 75 (75%) and 403 (60%) patients, and progression in 9 (9%) and 62 (9%), respectively. Surgery performed by residents was statistically associated with recurrence (HR = 0.69, 95% CI = 0.54-0.89) but not progression (HR = 0.72, 95% CI = 0.35-1.48). Surgical volume (b and c) was not found to have a significant impact on recurrence or progression in any of the analyses at the chosen cut-offs.

    Conclusions: Surgical experience (specialist/resident) was a predictive factor for recurrence after TUR-BT for Ta/T1 bladder cancer. However, surgeon volume was not associated with recurrence at the chosen cut-off levels. Training programs, checklist

    Impact of tumour size on recurrence and progression in Ta/T1 carcinoma of the urinary bladder2011In: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 45, no 6, p. 388-392Article in journal (Refereed)
    Abstract [en]

    Objective. This study aimed to evaluate the impact of tumour size on recurrence and progression in a population-based series of non-muscle-invasive bladder cancers. Material and methods. Clinical and pathological characteristics of patients with primary Ta/bladder cancer were registered. The patients tumours were categorized by size into five size groups (1-10, 11-20, 21-30, 31-40 and andgt;40 mm) or three size groups (1-15, 16-30 and andgt;30 mm). Results. The analysis included 768 evaluable patients with a mean follow-up of 60 months. Recurrence was observed in 478 patients (62%) and progression in 71 (9%). Tumour size was associated with recurrence for tumours sized 21-30, 31-40 and andgt;40 mm (p = 0.03, p andlt; 0.001, p andlt; 0.001, respectively) in the five size group and for tumours sized 16-30 and andgt;30 mm (p = 0.003 and p andlt; 0.001) in the three size group. Other factors affecting recurrence were T1 tumour category, multiplicity and surgery performed by residents (p andlt; 0.001, p andlt; 0.001, p = 0.002, respectively). Considering progression, there was no significant association with tumour size, and T1 category and local recurrence were the only significant risk factors (both p andlt; 0.001). Conclusion. Tumour size andlt;= 15 mm is associated with a lower risk of recurrence but not progression. Dividing tumour size into three size groups gives additional information compared with two size groups with cut-off at 30 mm.

    Residual tumour in the marginal resection after a complete transurethral resection is associated with local recurrence in Ta/T1 urinary bladder cancer2012In: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 46, no 5, p. 343-347Article in journal (Refereed)
    Abstract [en]

    Objective. This study investigated the presence of residual tumour in the marginal resection (MR) after a complete transurethral resection (TURB) of Ta/T1 transitional urinary bladder cancer. The association between positive MR and recurrence was analysed. Material and methods. After macroscopically complete TURB, a marginal resection of 7 mm (corresponding to the diameter of the resection loop) was removed around the entire resection area. Univariate and multivariate Cox regression analyses were performed to assess the influence of residual disease on recurrence. Results. In all, 94 patients with a median follow-up time of 36 months were included, and residual tumour in the MR was present in 24 (26%). The recurrence rates for all cases, for those with a tumour-positive and a tumour-free MR were 60 (64%), 20 (83%) and 40 (57%), respectively. Local recurrence was found in 14 (58%) of the patients with tumour presence in the MR compared to 13 (19%) of those with a tumour-free margin. A positive MR was significantly associated with overall recurrence (p andlt; 0.001) and local recurrence (p = 0.001). Conclusion. Incomplete transurethral resection of bladder cancer is common, as demonstrated in 26% patients with positive MR. The presence of tumour in the MR may be a risk factor for recurrence, and particularly local recurrence.

    Tumour location adjacent to the ureteric orifice in primary Ta/T1 bladder cancer is predictive of recurrence2016In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 50, no 1, p. 33-38Article in journal (Refereed)
    Abstract [en]

    Objective: The aim of this study was to evaluate tumour growth located around the ureteric orifice (LUO) at primary diagnosis of Ta/T1 urinary bladder cancer in relation to effects on recurrence and progression. Materials and methods: Clinical and pathological characteristics of patients diagnosed with primary Ta/T1 urinary bladder cancer from 1992 to 2007 were recorded prospectively. Location of the primary tumour and growth around the ureteric orifice (within 1 cm) were recorded and correlated with recurrence and progression during further follow-up. Hazard ratios (HRs) were estimated using Cox regression with 95% confidence intervals (CIs) in both univariate and multivariate analysis. Results: The study included 768 evaluable patients with a median follow-up of 60 months. Recurrence was observed in 478 patients (62%) and progression in 71 (9%). Growth of a primary tumour adjacent to the ureteric orifice was associated with recurrence (HR = 1.28, 95% CI = 1.07-1.54) but not progression (HR = 1.04, 95% CI = 0.65-1.67). The most common location of the first recurrence was the posterior bladder wall (29%). Other locations in the bladder did not predict recurrence or progression. Additional factors affecting recurrence were tumour size greater than 15mm, T1 tumour category, multiplicity, malignant or missing/not representative bladder wash cytology and surgery performed by residents. Conclusions: A primary tumour located around the ureteric orifice was predictive of recurrence, which could be taken into account in future follow-up schedules.

    Urinary bladder cancer treated with radical cystectomy: Perioperative parameters and early complications prospectively registered in a national population-based database2014In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 48, no 4, p. 334-340Article in journal (Refereed)
    Abstract [en]

    Objective. Cystectomy combined with pelvic lymph-node dissection and urinary diversion entails high morbidity and mortality. Improvements are needed, and a first step is to collect information on the current situation. In 2011, this group took the initiative to start a population-based database in Sweden (population 9.5 million in 2011) with prospective registration of patients and complications until 90 days after cystectomy. This article reports findings from the first year of registration. Material and methods. Participation was voluntary, and data were reported by local urologists or research nurses. Perioperative parameters and early complications classified according to the modified Clavien system were registered, and selected variables of possible importance for complications were analysed by univariate and multivariate logistic regression. Results. During 2011, 285 (65%) of 435 cystectomies performed in Sweden were registered in the database, the majority reported by the seven academic centres. Median blood loss was 1000 ml, operating time 318 min, and length of hospital stay 15 days. Any complications were registered for 103 patients (36%). Clavien grades 1-2 and 3-5 were noted in 19% and 15%, respectively. Thirty-seven patients (13%) were reoperated on at least once. In logistic regression analysis elevated risk of complications was significantly associated with operating time exceeding 318 min in both univariate and multivariate analysis, and with age 76-89 years only in multivariate analysis. Conclusions. It was feasible to start a national population-based registry of radical cystectomies for bladder cancer. The evaluation of the first year shows an increased risk of complications in patients with longer operating time and higher age. The results agree with some previously published series but should be interpreted with caution considering the relatively low coverage, which is expected to be higher in the future.

    Seventeen-year follow-up of the prospective randomized Nordic CIS study: BCG monotherapy versus alternating therapy with mitomycin C and BCG in patients with carcinoma in situ of the urinary bladder2016In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 50, no 5, p. 360-368Article in journal (Refereed)
    Abstract [en]

    Objective: The aim of this study was to compare the long-term efficacy of BCG monotherapy to alternating therapy of mitomycin C (MMC) and BCG in patients with carcinoma in situ (CIS). Materials and methods: Between 1992 and 1997, 321 patients with CIS were randomized from Finland, Norway and Sweden in a prospective multicenter trial into two treatment groups. The alternating therapy comprised six weekly instillations of MMC 40 mg followed by 10 instillations of BCG (Connaught 120 mg) or MMC alternating monthly for 1 year. BCG monotherapy followed the same 6 + 10 schedule. Stratification was done by nationality and CIS category. Primary endpoints were time to first recurrence and time to progression. Secondary endpoints were disease-specific mortality and overall survival. The main statistical methods were the proportional subdistribution hazards model and Cox proportional hazards model with the cumulative incidence and Kaplan-Meier analyses. Results: The median follow-up time was 9.9 years (maximum 19.9 years) in the BCG group and 8.9 years (maximum 20.3 years) in the alternating group. The risk of recurrence was significantly lower in the BCG group than in the alternating group (49 vs 59% at 15 years, respectively; hazard ratio 0.74, 95% confidence interval 0.54-1.00, p = 0.048). There were no significant differences in the other endpoints. Patients who progressed after 2 years were particularly prone to dying from bladder carcinoma. Younger patients performed worse than older ones. Conclusions: BCG monotherapy including monthly maintenance was effective and better than the alternating therapy. The risk of dying from bladder carcinoma after progression was high.

    Prospective study of transitional cell carcinoma in the prostatic urethra and prostate in the cystoprostatectomy specimen2007In: Scandinavian Journal of Urology and Nephrology, ISSN 0036-5599, E-ISSN 1651-2065, Vol. 41, no 4, p. 290-296Article in journal (Refereed)
    Abstract [en]

    Objectives. To prospectively evaluate the incidence of transitional cell carcinoma (TCC) in the prostatic urethra and prostate in the cystoprostatectomy specimen, investigate characteristics of bladder tumours in relation to the risk of involvement of the prostatic urethra and prostate and examine the sensitivity of preoperative loop biopsies from the prostatic urethra. Material and methods. Preoperatively, patients were investigated with cold cup biopsies from the bladder and transurethral loop biopsies from the bladder neck to the verumontanum. The prostate and bladder neck were submitted to sagittal whole-mount pathological analysis. Results. The incidence of TCC in the prostatic urethra and prostate in the cystoprostatectomy specimen was 29% (50/175 patients). Age, previous bacillus Calmette-Guérin treatment, carcinoma in situ (Cis) in the cold cup mapping biopsies and tumour grade were not associated with the risk of TCC in the prostatic urethra/prostate. Cis, multifocal Cis (≥2 locations) and tumour location in the trigone were significantly more common in cystectomy specimens with TCC in the prostatic urethra and prostate: 21/50 (42%) vs 32/125 (26%), p=0.045, 20/50 (40%) vs 27/125 (22%), p=0.023, and 20/50 (40%) vs 26/125 (21%), p=0.01, respectively. Preoperative resectional biopsies from the prostatic urethra in the 154 patients analysed identified 31/47 (66%) of patients with TCC in the prostatic urethra/prostate, with a specificity of 89%. The detection of stromal-invasive and non-stromal involvement was similar: 66% and 65%, respectively. Conclusions. The incidence of TCC in the prostatic urethra and prostate was 29% (50/175) in the cystoprostatectomy specimen. Preoperative biopsies from the prostatic urethra identified 66% of patients with such tumour growth. Our findings suggest that preoperative cold cup mapping biopsies of the bladder for detection of Cis add little extra information with regard to the risk of TCC in the prostatic urethra and prostate.

    Survival after radical cystectomy during holiday periods2021In: Scandinavian journal of urology, ISSN 2168-1805, E-ISSN 2168-1813, Vol. 55, no 4, p. 276-280Article in journal (Refereed)
    Abstract [en]

    Objective For patients undergoing radical cystectomy for bladder cancer, a procedure requiring complex urinary tract reconstruction prone to major postoperative complications, the timing and quality of the surgery have been associated with outcomes. Patients and methods This study investigated if radical cystectomy for bladder cancer performed during holiday periods had worse disease-specific (DSS) and overall survival (OS), higher 90-day mortality and risk of readmissions. All patients operated on with radical cystectomy for primary bladder cancer during 1997-2014 with holiday periods as exposure (with one narrow (7 weeks) and one wider (14 weeks) definition) in the Swedish population-based bladder cancer research-database (BladderBaSe) were studied. DSS and OS after radical cystectomy during holiday periods were analysed with Cox regression models adjusted for sex, age, comorbidity, marital status, T-stage and nodal metastases, neoadjuvant chemotherapy, hospital volume and year of cystectomy. Results Surgery during the holiday periods (narrow and wide definitions) were not associated with DSS (Hazard ratio [HR] = 1.05, 95% confidence interval [95% CI] = 0.90-1.21 and HR = 1.04, 95% CI = 0.91-1.17), respectively. HRs for OS were similar, and no associations between radical cystectomy during any of the holiday period definitions and 90-day mortality and readmission were found. Conclusion Survival after radical cystectomy in Sweden is similar during holiday and non-holiday periods.

    Cumulative incidence of midline incisional hernia and its surgical treatment after radical cystectomy and urinary diversion for bladder cancer: A nation-wide population-based study2021In: PLOS ONE, E-ISSN 1932-6203, Vol. 16, no 2, article id e0246703Article in journal (Refereed)
    Abstract [en]

    Background and objective To study the cumulative incidence and surgical treatment of midline incisional hernia (MIH) after cystectomy for bladder cancer. Methods In the nationwide Bladder Cancer Data Base Sweden (BladderBaSe), cystectomy was performed in 5646 individuals. Cumulative incidence MIH and surgery for MIH were investigated in relation to age, gender, comorbidity, previous laparotomy and/or inguinal hernia repair, operative technique, primary/secondary cystectomy, postoperative wound dehiscence, year of surgery, and period-specific mean annual hospital cystectomy volume (PSMAV). Results Three years after cystectomy the cumulative incidence of MIH and surgery for MIH was 8% and 4%, respectively. The cumulative incidence MIH was 12%, 9% and 7% in patients having urinary diversion with continent cutaneous pouch, orthotopic neobladder and ileal conduit. Patients with postoperative wound dehiscence had a higher three-year cumulative incidence MIH (20%) compared to 8% without. The corresponding cumulative incidence surgery for MIH three years after cystectomy was 9%, 6%, and 4% for continent cutaneous, neobladder, and conduit diversion, respectively, and 11% for individuals with postoperative wound dehiscence (vs 4% without). Using multivariable Cox regression, secondary cystectomy (HR 1.3 (1.0-1.7)), continent cutaneous diversion (HR 1.9 (1.1-2.4)), robot-assisted cystectomy (HR 1.8 (1-3.2)), wound dehiscence (HR 3.0 (2.0-4.7)), cystectomy in hospitals with PSMAV 10-25 (HR 1.4 (1.0-1.9)), as well as cystectomy during later years (HRs 2.5-3.1) were all independently associated with increased risk of MIH. Conclusions The cumulative incidence of MIH was 8% three years postoperatively, and increase over time. Avoiding postoperative wound dehiscence after midline closure is important to decrease the risk of MIH.

    Period-specific mean annual hospital volume of radical cystectomy is associated with outcome and perioperative quality of care: a nationwide population-based study2019In: BJU International, ISSN 1464-4096, E-ISSN 1464-410X, Vol. 124, no 3, p. 449-456Article in journal (Refereed)
    Abstract [en]

    Objective To investigate the association between hospital volume and overall survival (OS), cancer-specific survival (CSS), and quality of care of patients with bladder cancer who undergo radical cystectomy (RC), defined as the use of extended lymphadenectomy (eLND), continent reconstruction, neoadjuvant chemotherapy (NAC), and treatment delay of We used the Bladder Cancer Data Base Sweden (BladderBaSe) to study survival and indicators of perioperative quality of care in all 3172 patients who underwent RC for primary invasive bladder cancer stage T1-T3 in Sweden between 1997 and 2014. The period-specific mean annual hospital volume (PSMAV) during the 3 years preceding surgery was applied as an exposure and analysed using univariate and multivariate mixed models, adjusting for tumour and nodal stage, age, gender, comorbidity, educational level, and NAC. PSMAV was either categorised in tertiles, dichotomised (at amp;gt;= 25 RCs annually), or used as a continuous variable for every increase of 10 RCs annually. Results PSMAV in the highest tertile (amp;gt;= 25 RCs annually) was associated with improved OS (hazard ratio [HR] 0.87, 95% confidence interval [CI] 0.75-1.0), whereas the corresponding HR for CSS was 0.87 (95% CI 0.73-1.04). With PSMAV as a continuous variable, OS was improved for every increase of 10 RCs annually (HR 0.95, 95% CI 0.90-0.99). Moreover, higher PSMAV was associated with increased use of eLND, continent reconstruction and NAC, but also more frequently with a treatment delay of amp;gt;3 months after diagnosis. Conclusions The current study supports centralisation of RC for bladder cancer, but also underpins the need for monitoring treatment delays associated with referral.
