The effect of surgery on the survival status of patients with locally advanced cervical cancer after radiotherapy/chemoradiotherapy: a meta-analysis

Abstract

Background

To determine the effect of surgery on the survival status of patients with locally advanced cervical cancer after radiotherapy/chemoradiotherapy.

Methods

PubMed, Web of Science, ProQuest and Medline were searched using the key words "cervical cancer", "locally advanced disease", "radiotherapy" and "surgery or hysterectomy". Eight articles were selected and analysed using the STATA 12.0 software package. The log hazard ratio (HR) and its standard error for overall survival were calculated to assess the effect of surgery on patients with locally advanced cervical cancer after radiotherapy/chemoradiotherapy.

Results

In total, 2176 patients with locally advanced cervical cancer were identified. The pooled HR for overall survival was 1.13 (95% confidence interval (CI) 0.906–1.409), and there were no differences among the eight manuscripts (z = 1.08, p = 0.278). In the subgroup analysis, the pooled HR for overall survival was 1.169 (95% CI 0.924–1.480), and no differences among patients with stage IB-IIB disease were found in six articles (z = 1.30, p = 0.193). There was no publication bias regarding overall survival or stage IB-IIB disease.

Conclusions

This meta-analysis suggested that surgery had no effect on overall survival after radiotherapy/chemoradiotherapy; therefore, it is not recommended for patients with locally advanced cervical cancer.
