Gender-Based Response to Hypomethylating Agents

Leuk Lymphoma; ePub 2016 Oct 24; DeZern, et al

There is gender-based response variability to first-line therapy for higher-risk myelodysplastic syndromes, according to a study involving 642 individuals.

Investigators analyzed the influence of gender on overall survival and other outcomes in participants treated with decitabine (DAC) or azacitidine (AZA). Among the results:

  • Patients treated with DAC had slightly better median overall survival (~19 months) than their AZA-treated counterparts (~16 months); the difference varied substantially by sex.
  • DAC-treated females had longer median overall survival (~21 months), vs AZA-treated females (~13 months).
  • Survival was similar in males in both groups (~18 months for both).
