Tumor cells with MDR would now show a low sensitivity to anti-tumor agents, making chemotherapy ineffective or of little effect. Moreover, MDR is one of the pathogenetic factors for inducing refractory leukemia.展开更多

The quality assessment was conducted and network Meta-analysis was performed to compare the efficacy and safety of different CHIs plus transcatheter hepatic arterial chemoembolization(TACE). Primary outcomes were 1-year and 2-year survival rate, the secondary outcomes includes the clinical effective rate, performance status and the adverse reactions(ADRs). Data analysis was applied Stata 13.0 and Win BUGS 1.4 software.RESULTS: A total of 105 randomized controlled trials(RCTs) were identified for inclusion in this analysis, with data for 7683 patients and 13 CHIs. The results suggested that Javanica oil emulsion,Huachansu injection plus TACE were more favorable for 1-year and 2-year survival rate than other CHIs. Kanglaite, Astragalus polysaccharide injection plus TACE showed superiority in the clinical effective rate and performance status over other CHIs.And Shenmai injection plus TACE was superior to reducing ADRs than other CHIs for patients with liver cancer.CONCLUSION: Our findings indicated that receiving CHIs combined with TACE may have therapeutic benefits for patients with liver cancer in improving survival rate, clinical effective rate, the performance status and alleviating the ADRs.展开更多
