Abstract

Patients with high‑risk myelodysplastic syndromes (MDS) treated with azacitidine (AZA) have exhibited improved overall survival. However, information on AZA in real‑world settings is limited. The present study retrospectively analyzed 85 patients with MDS treated with AZA. Complete response was achieved in 24% of cases and hematologic improvement in 29%. Severe adverse events (grade ≥3) included neutropenia and infection. Multivariate analysis identified higher revised international prognostic scoring system (IPSS‑R) and male sex as significant factors affecting survival. However, the present study did not identify any significant associations between patient characteristics and response to AZA. In conclusion, AZA could produce a hematologic response in ~53% of patients with MDS. Furthermore, IPSS‑R may reflect MDS prognosis. Further studies are required to establish the criteria for identifying patients likely to obtain maximum benefit from AZA treatment.
