Efficacy and safety of endostar combined with chemoradiotherapy versus chemoradiotherapy alone in locally advanced cervical cancer: A PRISMA-compliant systematic review and meta-analysis.

BACKGROUND

To evaluate the role and safety of endostar in cervical cancer by comparing the efficacy and adverse reactions of endostar combined with concurrent chemoradiotherapy in patients with locally advanced cervical carcinoma.

METHODS

The quality of the included literature was evaluated by searching the database for the comparison of endostar combined with concurrent radiotherapy and chemotherapy in cervical cancer patients; objective response rate (ORR) and disease control rate (DCR) were used as the main outcome indicators, and statistical analysis was performed using RevMan5.3 and State15.3 software.

RESULTS

A total of 13 studies were included in this study, including 1057 patients with locally advanced cervical cancer, suggesting that endostar combined with chemoradiotherapy can significantly improve the objective response rate (ORR: odds ratio 3.88, 95% confidence interval 2.77-5.45, P < .00001) and disease control rate (DCR: odds ratio 4.43, 95% confidence interval 2.78-7.04; P < .00001), and there was no significant increase in treatment-related adverse reactions.

CONCLUSIONS

In this meta-analysis, endostar combined with concurrent chemoradiotherapy significantly improved ORR and DCR in patients with locally advanced cervical cancer without increasing toxicity. However, this study only analyzed the short-term efficacy of endostar, and its influence on overall survival and progression-free survival needs to be further verified in large randomized controlled trials with long-term follow-up.
