Title:

Long-Term Follow up of a Randomized Phase 2 Study of Low-Dose Decitabine Versus Low-Dose Azacitidine in Lower-Risk Myelodysplastic Syndromes

Excerpt:
A total of 113 pts were treated: 73 with decitabine and 40 with azacitidine…On multivariate analysis, age, U2AF1, TP53, and DNMT3A mutations all correlate with poor OS…Mutations had similar effects on OS regardless of HMA used….Low-doses of HMA in pts with lower-risk MDS are safe and can improve outcomes compared to historical data in pts with intermediate or high risk features by the MDA-LRPSS.
