Preoperative concomitant chemoradiotherapy in locally advanced cervical cancer: Safety, outcome, and prognostic measures

Abstract

Objectives To evaluate the morbidity, and the therapeutic value of surgery after chemoradiation in a large series of locally advanced cervical cancers (LACC). The prognostic role of different clinico-pathological factors has been also evaluated. Methods Between October 1997 and October 2006, 161 LACC patients were treated at both the Gynecologic Oncology Units of the Catholic University of Rome and Campobasso. Radiotherapy was administered to the whole pelvic region in combination with cisplatin and 5-fluorouracil. Radical surgery was performed 5–6 weeks after the end of the treatment. Results A clinical complete/partial response was observed in 153 patients and radical surgery was performed in 152 cases. The overall rate of surgical complications was 33% with 15 (10%) patients experiencing severe toxicities. At pathological examination 111 of 152 patients (73%) showed absent/microscopic residual disease. With a median follow-up of 28 months, the 5-year disease free-survival (DFS) was 83% and the 5-year overall survival (OS) 90%. Advanced FIGO (Federation Internationale de Gynecolgie et d'Obstetrique) stage, pathological response and lymph node involvement were found significantly associated with clinical outcome. Conclusions We confirmed in a larger series the safety and efficacy of this multimodal approach in the treatment of LACC. The pathological assessment of response can allow not only a tailored surgery in selected patients, but also the identification of patients with higher risk of recurrence to be submitted to adjuvant therapies.
