Survival in Azacitidine-Treated Patients Assessed

Leuk Res; 2017 Oct 27; Sébert, Komrokji et al

People with myelodysplastic syndrome (MDS) who received azacytidine and achieved complete cytogenetic response (CCyR) experienced better overall survival than those who did not achieve such, according to a study involving >700 individuals. Participants had either higher risk MDS or low blast count acute myeloid leukemia, and included those with abnormal karyotype. Investigators looked at the prognostic impact of baseline cytogenetics and cytogenic response (CyR) on overall response and survival rates. In 281 evaluable patients with abnormal cytogenics:

  • CyR was achieved in ~one-third.
  • CCyR was attained in one-fourth.
  • CyR did not impact survival overall.
  • Those with MDS who achieved CCyR experienced better overall survival.
