Long-term analysis of clinical outcome and complications in locally advanced cervical cancer patients administered concomitant chemoradiation followed by radical surgery

Objective. Preoperative chemoradiation (CT/RT) has been shown to achieve encouraging results in terms of clinical outcome in locally advanced cervical cancer (LACC). The study aims at analyzing the long-term results of this multimodal approach in a single institution series of 184 cases. Methods. Patients underwent whole pelvic irradiation combined with cisplatin and 5-fluorouracil. After evaluation of clinical response, patients were triaged to surgery. Surgical morbidity was classified according to Chassagne grading system. Univariate and multivariate analyses were used to assess the prognostic and predictive role of clinicopathological parameters. Results. Clinical response was observed in 96.1% of cases. A total of 174 cases were submitted to radical surgery: 124 patients (71.3%) showed complete/microscopic pathological response. In multivariate analysis, clinical response, stage of disease, and histotype predicted response to CT/RT. With a median follow-up of 58 months, recurrence and death of disease were observed in 42 and 40 patients, respectively. The 5-year DFS was 75.5%, while the 5-year OS was 77.4%. Patients with no residual disease showed a significant longer DFS than patients with microscopic (p value = 0.0128), and macroscopic (p value = 0.0001) residual tumor after treatment. In multivariate analysis, residual tumor and stage of disease were the two most relevant prognostic factors for DFS and OS. As far as long-term toxicity is concerned, 8 out of 22 complications were grade 3/4. Conclusion. Preoperative CT/RT is worth further investigation in LACC patients, providing encouraging survival outcomes and a favourable long-term toxicity profile. (C) 2010 Elsevier Inc. All rights reserved.
