Abstract:
Objective:To demonstrate the type of CEBPA gene mutations among patients with acute myeloid leukemia (AML), clinical characteristics, and prognostic effect on patient outcomes.Methods:Demographic data, clinical features, laboratory characteristics, and data about treatment and follow-up of 57 patients with CEBPA mutated AML diagnosed at Peking Union Medical College Hospital between April 2016 and November 2022 were collected and analyzed.Results:In total, 57 patients with CEBPA mutation accounted for 16.1% of all the 353 patients with AML, among which 28 patients had CEBPA-bZIPinf and 29 had CEBPA-other. Compared with the CEBPA-other group, the CEBPA-bZIPinf group was younger (54 vs 64 years, P=0.010), de novo AML was more common ( P=0.001), and the level of bone marrow blast was higher (68.0% vs 36.3%, P=0.001). Moreover, 24 patients from the CEBPA-bZIPinf group and 19 from the CEBPA-other group received chemotherapy. The one-course complete remission (CR) rate of the CEBPA-bZIPinf group was significantly higher than that of the CEBPA-other (87.5% vs 47.4%, P=0.010) and CEBPA-wt (87.5% vs 50.3%, P=0.002) groups. After a median follow-up of 11 months, the median OS of the CEBPA-bZIPinf group was significantly longer than that of the CEBPA-wt group (not reached vs 22.1 months, P=0.012) . Conclusion:CEBPA-bZIPinf mutated AML is a unique clinical entity, with a younger age of diagnosis, better response to chemotherapy, and better prognosis.
