Operation for locally advanced cervical cancer after concurrent chemoradiotherapy

This paper aimed to discuss the scope of operation and clinical effects for locally advanced cervical cancer (LACC) after concurrent chemoradiotherapy (CCRT).

We retrospectively reviewed the records of 444 patients with stages IB2-IIB cervical cancer who were divided into two groups whether or not they received CCRT before radical operation in our institute from January 2013 to December 2016. Patients' characteristics, treatments, and outcomes were analyzed.

The total efficiency (CR + PR) of the CCRT + operation group was 96.2%. Specifically, the CR rate was 9.1%, and the PR rate was 87.1%. The positive rates of cervical deep interstitial infiltration, lymphatic metastasis, and lymphangial infiltration of the operation group were significantly higher than those of the CCRT + operation group (P < 0.05). A total of 24 and 162 patients in the CCRT + operation group and the operation group, respectively, received adjuvant therapy (P < 0.05). The incidence rate of edema of the lower extremity, radiation enteritis, and radiocystitis after postoperative adjuvant radiotherapy in the operation group was significantly higher than that of the CCRT + operation group (P < 0.05). The 5-year survival rates and 5-year progression-free survival (PFS) rates of the CCRT + operation and operation groups were 79.3% versus 64.0% and 68.9% versus 45.2%, respectively (P < 0.05).

Comprehensive treatment that combines CCRT and radical operation to LACC achieves satisfying clinical effects without increasing the occurrence rate of intraoperative and postoperative complications. Moreover, such treatment can improve the 5-year PFS rate and OS rate.
