Surgery after concurrent chemoradiotherapy and brachytherapy for the treatment of advanced cervical cancer: Morbidity and outcome: Results of a multicenter study of the GCCLCC (Groupe des Chirurgiens de Centre de Lutte Contre le Cancer)

Objectives. To evaluate the morbidity and therapeutic value of surgery after concurrent chemoradiotherapy and brachytherapy in a multicentric series of patients with advanced cervical cancer. Methods. Patients with stage IB2 to IVA cervical cancer treated with concurrent chemoradiotherapy and pelvic radiotherapy followed by brachytherapy and surgery from seven participating French comprehensive cancer centers were enrolled. The surgical treatment consisted of a hysterectomy, which ranged from radical hysterectomy to anterior pelvic exenteration, and lymph node resection. Acute toxicity, pathological response, overall, and disease-free survival were assessed for each pathological response to therapy. Results. One hundred seventy-five patients were enrolled from September 1987 to June 2002. The median age was 44 years [27;75]. Patients distribution according to clinical classification was as follows: 41 stage IB2, 18 IIA, 77 IIB, 12 IIIA, 14 IIIB, and 13 IVA. Forty-six patients experienced 51 postoperative complications. Thirty-three patients experienced grade 2 morbidity (18.9%, 33/175), among whom 19 experienced urinary complications (57.5%, 19/175). No post treatment mortality was observed. Grade 3 toxicity rate was 6.9% (12/175). Pathological complete response rate was 38% (67/175). After a median follow-up of 36 months, overall survival and disease-free survival were significantly better in patients who had a pathological complete response to therapy than those who achieved a partial pathological response (P < 0.0001). Conclusion. Surgery after concurrent chemoradiotherapy and brachytherapy for advanced cervical cancer leads to an acceptable morbidity. Furthermore, surgery allows evaluation of the pathological response to therapy and improves local control in the case of partial pathological response. (c) 2006 Elsevier Inc. All rights reserved.
