Meta-analysis on efficacy and safety of thalidomide combined with CAG regimen in the treatment of elderly patients with acute myeloid leukemia
OBJECTIVE To systematically evaluate the efficacy and safety of thalidomide combined with aclacinomycin,granulocyte colony-stimulating factor and cytarabine(CAG)regimen in the treatment of elderly patients with acute myeloid leukemia(AML).METHODS CNKI,Wanfang data,VIP,Sino Med,PubMed,Embase,the Cochrane Library and Web of Science were searched comprehensively from the inception to Aug.27th,2023.Randomized controlled trials(RCTs)about thalidomide combined with CAG regimen(trial group)versus CAG regimen(control group)in the treatment of elderly AML patients were collected,and RevMan 5.3 software was used for meta-analysis of included studies.RESULTS Finally,7 RCTs were included,with a total of 601 patients,including 307 patients in the trial group and 294 patients in the control group.Meta-analysis results showed that the trial group was superior to the control group in enhancing the overall response rate[Z=4.75,P＜0.000 01,OR=2.80,95%CI(1.83,4.28)],complete remission rate[Z=2.82,P=0.005,OR=1.61,95%CI(1.16,2.25)],and improving platelet count[Z=2.70,P=0.007,MD=64.02,95%CI(17.53,110.51)],vascular endothelial growth factor[Z=13.63,P＜0.000 01,MD=-65.17,95%CI(-74.54,-55.80)],vascular endothelial growth factor receptor[Z=12.03,P＜0.000 01,MD=-499.01,95%CI(-580.31,-417.71)]and basic fibroblast growth factor[Z=4.17,P＜0.000 1,MD=-0.23,95%CI(-0.35,-0.12)].And there was no statistical difference between the trial group and the control group in the incidence of adverse drug reaction[Z=0.99,P=0.32,OR=0.52,95%CI(0.14,1.89)],nausea and vomiting[Z= 1.06,P=0.29,OR=0.66,95%CI(0.30,1.43)],constipation or diarrhea[Z=0.92,P=0.36,OR=0.65,95%CI(0.26,1.63)],drowsiness[Z=1.38,P=0.17,OR=0.57,95%CI(0.26,1.27)]or myelosuppression[Z=0.88,P=0.38,OR=0.68,95%CI(0.28,1.62)].CONCLUSIONS The combination of thalidomide and CAG regimen in the treatment of elderly AML patients can significantly improve clinical efficacy and has high safety.
