OBJECTIVE@#To investigate the efficacy and safety of venetoclax (VEN) combined with demethylating agents (HMA) in the treatment of relapsed/refractory acute myeloid leukemia (R/R AML).@*METHODS@#The clinical data of 26 adult R/R AML patients who received the combination of VEN with azacitidine (AZA) or decitabine (DAC) in Huai'an Second People's Hospital from February 2019 to November 2021 were retrospectively analyzed. The treatment response, adverse events as well as survival were observed, and the factors of influencing the efficacy and survival were explored.@*RESULTS@#The overall response rate (ORR) of 26 patients was 57.7% (15 cases), including 13 cases of complete response (CR) and CR with incomplete count recovery (CRi) and 2 cases of partial response (PR). Among the 13 patients who got CR/CRi, 7 cases achieved CRm (minimal residual disease negative CR) and 6 cases did not, with statistically significant differences in overall survival (OS) and event-free survival (EFS) between the two groups (P=0.044, 0.036). The median OS of all the patients was 6.6 (0.5-15.6) months, and median EFS was 3.4 (0.5-9.9) months. There were 13 patients in the relapse group and refractory group, respectively, with response rate of 84.6% and 30.8% (P=0.015). The survival analysis showed that the relapse group had a better OS than the refractory group (P=0.026), but there was no significant difference in EFS (P=0.069). Sixteen patients who treated for 1-2 cycles and 10 patients who treated for more than 3 cycles achieved response rates of 37.5% and 90.0%, respectively (P=0.014), and patients treated for more cycles had superior OS and EFS (both P<0.01). Adverse effects were mainly bone marrow suppression, complicated by various degrees of infection, bleeding, and gastrointestinal discomfort was common, but these could be all tolerated by patients.@*CONCLUSION@#VEN combined with HMA is an effective salvage therapy for patients with R/R AML and is well tolerated by patients. Achieving minimal residual disease negativity is able to improve long-term survival of patients.
