ABCC1 and acute myeloid leukemia: The current study failed to show any significant associations between the poly-miRTS of anthracycline-pathway genes and CR or OS/RFS of AML; however, we did show that four poly-miRTS were associated with chemotherapy toxicity, i.e., ABCC1 rs3743527, rs212091, and rs212090 were significantly associated with myelosuppression and gastrointestinal reaction, which were reported to associate with a risk in developing lung cancer [42].
