A meta-analysis of recombinant human endostatin combined with NP regimen for treating non-small cell lung cancer.

BACKGROUND

The aim of this study was to evaluate the efficacy and safety of recombinant human endostatin in combination with vinorelbine + cisplatin (NPE) for the treatment of advanced non-small cell lung cancer (NSCLC).

METHODS

Randomized controlled trials (RCTs) of NPE for advanced NSCLC in PubMed, Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure, and Wanfang databases were searched using a computerized search of the database from the time of creation to May 2023. Two investigators independently extracted literature information and assessed the quality of the included literature. Meta-analysis was performed using RevMan 5.4.0 software.

RESULTS

A total of 24 RCTs with 2114 patients with advanced NSCLC were finally included. The results of meta-analysis showed that the total effective rate in the group received NPE regimen was significantly higher than those in the group without NPE regimen (RR = 1.70, 95% CI: 1.48-1.95, P < .00001). Meanwhile, the clinical benefit rate in the group received NPE regimen was also significantly higher than those in the group without NPE regimen (RR = 1.22, 95% CI: 1.15-1.29, P < .00001). However, there was no significant difference in the incidence of adverse event rate between the 2 groups (RR = 0.98, 95% CI: 0.76-1.27, P = .88).

CONCLUSIONS

Compared with NP (vinorelbine + cisplatin) regimens for patients with advanced NSCLC, NPE regimens improve the total effective rate and clinical benefit rate of treatment, but there can be no significant difference in adverse effects. Prospective randomized trials are needed to further validate the safety and efficacy of this treatment modality.
