Functional organ preservation in patients with locoregionally advanced head and neck squamous cell carcinoma treated by platinum-based multidrug induction chemotherapy and concurrent chemoradiotherapy.

摘要

BACKGROUND: The objective of this study was to evaluate the feasibility, safety, and efficacy in terms of functional organ preservation of multidrug induction chemotherapy and concurrent chemoradiotherapy (IC-CCRT) protocol in patients with locoregionally advanced head and neck squamous cell carcinoma (LA-HNSCC). PATIENTS AND METHODS: Patients with previously untreated, inoperable, histologically proven nonmetastatic stage III or IV HNSCC were eligible. Following one cycle of IC, two cycles of cisplatinum and 5-fluorouracil CCRT with conventional fractionated radiotherapy up to a dose of 66-70 Gy were administrated. RESULTS: Between January 2000 and July 2007, a total of 139 patients were candidates to receive IC-CCRT for LA-HNSCC. Overall, 83% of the patients completed the treatment. Three-year overall survival estimate was 68% [95% confidence interval (CI) 57% to 79%]. Three-year progression-free survival (PFS) estimate was 62% (95% CI 50% to 74%). Three-year functional PFS was 57% (95% CI 44% to 69%). There were no cases of treatment-related deaths. The most frequent severe acute toxicity was pharyngeal mucositis. CONCLUSIONS: Cisplatinum-based multidrug IC-CCRT can result in functional organ preservation and curative treatment in most patients with LA-HNSCC. The toxicity profile and patients' compliance to treatment confirmed the safety and tolerability of this approach.
