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.
