Resumen
Azacitidine (AZA) is an essential drug in the treatment of myelodysplastic syndromes (MDS) that has made it possible to extend patients? survival and improve their quality of life. Unfortunately, despite the widespread use of AZA, its prognostic factors for response still remain unknown. Here, we retrospectively analyzed the efficacy and safety of AZA therapy in 79 patients with MDS in a real-life setting. Furthermore, we provided some potential biomarkers of response and survival. The study confirmed that the achievement of response to AZA is not mandatory for obtaining a survival benefit in patients with MDS. Unfavorable cytogenetic risk was determined to be the most negative prognostic factor for both response and survival. Moreover, older age, a complex or monosomal karyotype, higher IPSS or IPSS-R risk and a higher level of serum ferritin level were associated with significantly shorter survival.
