Recent data suggest that azacitidine may be beneficial in CMML. We report on 48 CMML-patients treated with azacitidine. Overall response rates were high (70% according to IWG-criteria, including 22% complete responses). Monocyte count and cytogenetics adversely affected survival, whereas age, WHO-type, FAB-type, and spleen size did not. Matched-pair analyses revealed a trend for higher two-year-survival for azacitidine as compared to best supportive care (62% vs. 41%, p=0.067) and longer OS for azacitidine first-line vs. hydroxyurea first-line (p=0.072, median OS 27.7 vs. 6.2 months). This report reinforces existing evidence that azacitidine is safe and efficacious in both myelodysplastic and myeloproliferative CMML.
