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 and 5-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.
