Abstract

BACKGROUND: In 'real-life', the Nordic score guides ESA use in lower-risk MDS with predicted response rates of 25% or 74%. As new treatments emerge, a more discriminating score is needed. OBJECTIVES: To validate existing ESA predictive scores and develop a new score that identifies non-responders. METHODS: ESA-treated patients were identified in 3 MDS registries in Italy and Canada (FISM 555, GROM 233, MDS-CAN 208). Clinical and disease-related variables were captured. Nordic, MDS-CAN and IPSS-R-based ESA scores were calculated and documented ESA responses compared. RESULTS: 996 ESA-treated patients were identified. Overall response rate(ORR) was 59%. The database was randomly divided into balanced derivation (n=463) and validation (n=462) cohorts. By multivariate analysis, transfusion independence, erythropoietin level
