Objective To explore the effectiveness and safety of Jianpi Yishen Prescription combined with CAG regimen, namely, cytarabine plus aclarubicin plus recombinant human granulocyte colony⁃stimulating factor, for the treatment of elderly acute myeloid leukemia (AML). Methods A total of 132 elderly AML patients were randomly divided into control group or observation group, with 66 cases in each group. The control group received CAG regimen for treatment, based on which the observation group received Jianpi Yishen Prescription for treatment. The blood routine, blood biochemical indices with respect to serum ALT, AST, β2⁃microglobulin, lactate dehydrogenase, creatinine, urea nitrogen levels and quality of life before and after treatment, as well as post⁃treatment clinical efficacy, blood transfusion volume during treatment (transfusion volume of red blood cell suspension, transfusion volume of platelet) and adverse reactions were compared between the two groups. Results After treatment, the total effective rate in the observation group was higher than that in the control group, and the transfusion volumes of red blood cell suspension and platelet were lower than those in the control group (P<0.05). After treatment, patients of both groups obtained higher white cell counts, neutrophil counts, blood platelet counts, reticulocyte counts, and higher levels of serum ALT, AST, creatinine, as well as higher quality of life as compared with before treatment, whereas lower hemoglobin, serum β2⁃microglobulin and lactate dehydrogenase levels as compared with before treatment. Among which the observation group exhibited higher white cell counts, neutrophil counts, blood platelet counts, reticulocyte counts, and higher levels of serum AST, creatinine, and urea nitrogen, whereas lower levels of hemoglobin, serum ALT, β2⁃microglobulin, and lactate dehydrogenase as compared with the control group (P<0.05). There was no statistically significant difference in the total incidence rate of adverse reactions between the two groups (P>0.05). Conclusion Jianpi Yishen Prescription combined with CAG regimen for the treatment of elderly AML patients can improve their clinical efficacy and quality of life, relieve response to hematological toxicity, with a favorable safety.
