These Patients with CBF-AML Benefit Most from HMAs

Am J Hematol; 2017 Sep; Ragon, Daver, et al

A subset of patients with core binding factor acute myeloid leukemia (CBF-AML) appear to derive the most benefit from maintenance hypomethylating agents (HMAs), according to a study involving 23 individuals.

Participants were a median 53 years of age, had CBF-AML, and received HMA therapy following induction/consolidation. Among the results:

  • 17 patients had a detectable reverse transcriptase polymerase chain reaction (RTPCR) levels when HMA was started.
  • 5 patients had progressive disease and experienced increased RTPCR over 1 to 2 cycles of HMA therapy.
  • 12 patients who did not fail HMA had a median RTPCR at HMA initiation of 0.06.
  • 11 of these patients had a reduction in RTPCR after the first or second cycle of HMA.

The authors concluded that patients with low RTPCR levels following induction/consolidation chemotherapy derive the most benefit from HMA therapy, especially those whose levels were reduced within the first 2 treatment cycles.
