Objective:
In this meta-analysis, we aimed to evaluate the oncological outcomes of preoperative neoadjuvant chemotherapy followed by radical surgery compared with radical surgery alone for treatment of International Federation of Gynecology and Obstetrics (FIGO) stage I-II cervical cancer.
Method:
We searched for studies comparing the safety and efficacy of neoadjuvant chemotherapy plus surgery versus surgery alone in treatment outcomes of locally advanced cervical cancer. Meta-analysis was used to calculate the pooled odds ratios with corresponding 95% confidence intervals (CI).
Results:
Sixteen studies were included in our analysis. Pooled analysis of overall survival rate [odds ratio (OR) = 1.09, 95% CI: 0.83-1.43] and progression-free survival rate (OR = 1.10, 95% CI: 0.77-1.57) showed that preoperative neoadjuvant chemotherapy did not have a benefit compared with surgery alone in terms of survival rates. The pooled results for postoperative parameters indicated that preoperative neoadjuvant chemotherapy followed by radical surgery was associated with a high rate of vascular space involvement (OR = 0.25, 95% CI: 0.17-0.35) and parametrial infiltration (OR = 0.60, 95% CI: 0.45-0.79).
Conclusions:
This meta-analysis indicated that surgery following neoadjuvant chemotherapy for FIGO stage I-II cervical cancer and surgery alone had similar oncological outcomes.
