Abstract [en]

The myelodysplastic syndromes (MDS) have highly variable outcomes and prognostic scoring systems are important tools for risk assessment and to guide therapeutic decisions. However, few population-based studies have compared the value of the different scoring systems. With data from the nationwide Swedish population-based MDS register we validated the International Prognostic Scoring System (IPSS), revised IPSS (IPSS-R) and the World Health Organization (WHO) Classification-based Prognostic Scoring System (WPSS). We also present population-based data on incidence, clinical characteristics including detailed cytogenetics and outcome from the register. The study encompassed 1329 patients reported to the register between 2009 and 2013, 14% of these had therapy-related MDS (t-MDS). Based on the MDS register, the yearly crude incidence of MDS in Sweden was 2amp;lt;boldamp;gt;amp;lt;/boldamp;gt;9 per 100000 inhabitants. IPSS-R had a significantly better prognostic power than IPSS (Pamp;lt;0amp;lt;boldamp;gt;amp;lt;/boldamp;gt;001). There was a trend for better prognostic power of IPSS-R compared to WPSS (P=0amp;lt;boldamp;gt;amp;lt;/boldamp;gt;05) and for WPSS compared to IPSS (P=0amp;lt;boldamp;gt;amp;lt;/boldamp;gt;07). IPSS-R was superior to both IPSS and WPSS for patients aged 70years. Patients with t-MDS had a worse outcome compared to de novo MDS (d-MDS), however, the validity of the prognostic scoring systems was comparable for d-MDS and t-MDS. In conclusion, population-based studies are important to validate prognostic scores in a real-world setting. In our nationwide cohort, the IPSS-R showed the best predictive power.
