CSF3R and acute myeloid leukemia: Induction responses were poorer in CSF3R‐mutated AML patients, with lower complete remission (55.6% vs. 78.8%, p = 0.004), reduced measurable residual disease (MRD) negativity (53.3% vs. 87.6%, p < 0.001), and shorter MRD maintenance duration (5.4 vs. 21.6 months, p < 0.001).
