A comparison of the efficacy of antiangiogenic agents combined with chemotherapy for the treatment of non-small cell lung cancer: a network meta-analysis.

Abstract

OBJECTION:

To explore the effects of combinations of antiangiogenic agents and chemotherapy agents on non-small cell lung cancer (NSCLC) patients and indirectly compare the therapeutic effect of Endostar combined with chemotherapy and bevacizumab combined with chemotherapy on NSCLC.

METHODS:

We searched 3 electronic databases: PubMed, Web of Science and the Cochrane Library. The ORRs, HRs and 95% confidence intervals of OS and PFS were used to compare the efficacy of Endostar combined with chemotherapy and bevacizumab combined with chemotherapy. We use the Bayesian network meta-analysis method to make indirect comparisons and obtain rank probabilities; in addition, we used single-arm meta-analysis to synthesize the existing data.

RESULTS:

A total of 29 studies were included in the analysis. Among them, we included a total of 14 interventions. A total of 12,862 patients participated in this analysis. The single-arm meta-analysis showed that the pooled ORR and 95% CI were 0.35 (0.31, 0.39), the pooled HR of OS and 95% CI were 0.89 (0.81, 0.98), and the pooled HR of PFS and 95% CI were 0.67 (0.56, 0.81). According to the results of network meta-analysis, there were no significant differences between the 5 kinds of bevacizumab combined with chemotherapy regimens and the 4 kinds of Endostar combined with chemotherapy regimens for improving ORR and prolonging OS and PFS. The rank probabilities suggested that in terms of ORR, Pla + Pem + Bev was the first-ranked intervention (0.288). Pla + Pem + Endo was the first-ranked intervention for prolonging OS (0.423) and Pla + Gem + Endo was the first-ranked intervention for prolonging PFS (0.302).

CONCLUSION:

Antiangiogenic agents combined with platinum-containing dual drugs can provide benefits to NSCLC patients. In addition, bevacizumab combined with chemotherapy regimens has better theraputic effect on ORR while Endostar combined with chemotherapy may have better effects on OS and PFS for the treatment of NSCLC patients.
