Abstract:Objective To explore the therapeutic efficacy of venetoclax combined with low-dose aclarubicin and cytosine arabinoside (AA) regimen for acute myeloid leukemia (AML) in the elderly.Methods The clinical data of 83 elderly AML patients treated in our hospital from February 2017 to December 2020 were retrospectively analyzed. Among them, 62 were treated with low-dose AA (recorded as the control group), and the other 21 cases were treated with venetoclax combined with low-dose AA (recorded as the study group). The short-term therapeutic efficacy and peripheral blood p53 content of the two groups were compared. The adverse reactions and the transfusion of blood products in the two groups were observed, and the drug safety during the treatment period and the survival status after six months of treatment in the two groups were analyzed.Results The objective response rate of the study group was higher than that of the control group (P < 0.05). The difference of p53 before and after the treatment in the study group was higher than the that in the control group (P < 0.05). The time to agranulocytosis and the time to platelet count < 20×109/L were shorter, and the amount of blood cell transfusion and that of platelet transfusion were lower in the study group compared with the control group (P < 0.05). There was no significant difference in the incidence of infection, rashes, liver damage, and gastrointestinal adverse drug reactions between the two groups (P > 0.05). There was 1 death in the study group and 7 deaths in the control group. In addition, there was no significant difference in the overall survival curve between the two groups (P > 0.05).Conclusions The venetoclax combined with low-dose AA regimen is effective and safe for the treatment of AML in the elderly.
