Completion surgery after intensity-modulated arc therapy for locally advanced cervical cancer: long-term follow-up and update on surgical outcome and oncologic results of a unique tertiary care single-center retrospective cohort

BACKGROUND: Chemoradiotherapy (CRT) followed by brachytherapy (BT) is the standard treatment for locally advanced cervical cancer (LACC), but replacement of BT by surgery (CRT-S) could be an acceptable alternative. The main concern is the risk of operative morbidity. The aim is to report on therapeu...

Sumario:BACKGROUND: Chemoradiotherapy (CRT) followed by brachytherapy (BT) is the standard treatment for locally advanced cervical cancer (LACC), but replacement of BT by surgery (CRT-S) could be an acceptable alternative. The main concern is the risk of operative morbidity. The aim is to report on therapeutic morbidity, OS, PC, and LC of CRT-S. METHODS: This was a single tertiary center retrospective cohort study in patients treated with CRT-S. A type II Wertheim hysterectomy was performed 6–8 weeks after CRT. Acute and chronic radiotherapy-related and surgical morbidity was classified according to the CTCAE v4.0. OS, and DFS, PC, and LC were calculated using the Kaplan-Meier method. Univariate and multivariate Cox proportional hazard models were performed to determine variables with a prognostic role. RESULTS: A total of 130 consecutive LACC patients were treated with CRT, and 119 underwent completion surgery. The median follow-up was 53 months. Five-year OS rate, local control, pelvic control, and 5-year DFS rate were 73%, 93%, 90%, and 74%, respectively. The 5-year OS rate was 92%/72%/67%/56% for FIGO (2009) stage I/II/III/IV, respectively. The five-year OS rate was 79% and 71% for adenocarcinoma and squamous cell carcinoma (p > 0.05), respectively. There was no intra- and perioperative mortality. Intraoperative and early postoperative complication rates were 7% and 20% (3% ≥ G3), respectively; they resolved within 3 months. The late postoperative complication rate was 9% (7% ≥ G3). Acute/late radiotherapy-related G3 side effects were 5%/3% for gastrointestinal and 3%/7% for genitourinary side effects. CONCLUSIONS: CRT-S is safe with an acceptable rate of complications for both the CRT and completion surgery and shows encouraging outcome data for stage III/IV and adenocarcinoma patients.
