Abstract

Objective: Few data exist regarding adjuvant hysterectomy (AH) in locally advanced cervical cancer (LACC) patients treated with chemoradiotherapy. We investigated the effect of AH on prognosis in LACC patients, through meta-analysis.

Methods: EMBASE and MEDLINE databases and the Cochrane Library were searched for published studies comparing LACC patients who received AH after chemoradiotherapy with those who did not, through April 2016. Endpoints were mortality and recurrence rates. For pooled estimates of the effect of AH on mortality/recurrence, random- or fixed-effects meta-analytical models were used.

Results: Two randomized trials and six observational studies (AH following chemoradiotherapy, 630 patients; chemoradiotherapy, 585 patients) met our search criteria. Fixed-effects model-based meta-analysis indicated no significant difference in mortality between the groups (odds ratio [OR]=1.01; 95% confidence interval [CI]=0.58?1.78; p=0.968) with low cross-study heterogeneity (p=0.73 and I2=0.0). This pattern was observed in subgroup analysis for study design, radiation type, response after chemoradiotherapy, and hysterectomy type. The pooled OR for AH and recurrence was 0.59 (95% CI=0.44?0.79; p<0.05) with low cross-study heterogeneity (p=0.29 and I2=17.8), favoring the AH group. However, this pattern was not observed in the subgroup analysis for the randomized trials. There was no evidence of publication bias.

Conclusion: In this meta-analysis, AH following chemoradiotherapy did not improve survival in patients with LACC, although it seemed to reduce the risk of recurrence. Concerning the significant morbidity of AH after chemoradiotherapy, routine use of AH should be avoided.
