Acceleration of hyperfractionated chemoradiation regimen for advanced head and neck cancer

Abstract

Background. Our aim was to evaluate the acceleration of a hyperfractionated, concurrent chemoradiation regimen (HxCRT) for advanced head and neck squamous cell carcinoma (HNSCC). Methods. Patients with unresectable HNSCC were treated based on a previously published HxCRT regimen: 1.25 Gy twice daily to 70 Gy concurrent with cisplatin 12 mg/m 2 /day and5-fluorouracil 600 mg/m 2 /day for 5 days, weeks 1, 5. This regimen was accelerated in this series by shortening the treatment from 7 to 6 weeks by omitting the planned mid-treatment 1-week break. Results. Forty-six patients with T3-4/N3 disease were treated. The main acute toxicity was pharyngeal. Median weight change during therapy in patients with and without enteral feeding tubes was −3.8% and −7.9%, respectively ( p = .08). Fifteen percent had late grade III pharyngeal toxicity. Local/regional and distant failure rates were 28% and 17%, respectively; 52% are alive without evidence of disease. Conclusions. In nonresectable HNSCC, acceleration of the HxCRT regimen is feasible, requiring enteral feeding tubes during therapy in most patients. © 2006 Wiley Periodicals, Inc. Head Neck, 2007
