Abstract

Background

The standard treatment for cervical cancer is chemoradiation although some patients showed treatment resistance. The purpose of this study was to investigate the clinical efficacy of surgery after chemoradiation for cervical cancer.

Methods

Patients with FIGO stage IB2 to IIB cervical cancer were included in the study between 2005 and 2015. A total of 50 patients who underwent surgery after neoadjuvant chemoradiation and 76 patients who received only chemoradiation were compared. Baseline differences between the two groups were adjusted with inverse probability of treatment weighting method using propensity scores composed of the following independent variables: age, stage, tumor size, lymph node metastasis, and histological subtypes.

Results

Median follow-up was 64.8 (range 4.8–143.9) months. After adjustment with inverse probability of treatment weighting, Kaplan–Meier curves showing adjusted progression-free survival and overall survival were significantly longer in the neoadjuvant chemoradiation compared with the chemoradiation-only group (p = 0.027 and p = 0.017, respectively). Moreover, in patients with squamous cell carcinoma, recurrence in previously irradiated field and recurrence both in and out of previously irradiated field were significantly decreased in the neoadjuvant chemoradiation compared with the chemoradiation-only group (3.1% and 18.4%, respectively; OR 0.142, p = 0.001]. Adverse events of surgery after chemoradiation were acceptable, although temporary hydronephrosis was frequently observed (23.1%).

Conclusions

Surgery after chemoradiation reduced pelvic recurrence, and as a result, patients who underwent neoadjuvant chemoradiation showed more favorable survival outcomes compared with those who only underwent chemoradiation.
