Primary Outcome Measures:
- Time to local recurrence [ Designated as safety issue: No ]
Secondary Outcome Measures:
- Length of survival [ Designated as safety issue: No ]
- Morbidity and toxicity [ Designated as safety issue: Yes ]
- Quality of life as assessed by EORTC Quality of life Questionnaire for Head and Neck Cancer [ Designated as safety issue: No ]
OBJECTIVES:
- Compare adjuvant continuous hyperfractionated accelerated radiotherapy vs conventional radiotherapy, in terms of preventing disease recurrence, in patients with head and neck cancer.
- Compare the early and late toxic effects of these treatments in this patient population.
- Compare disease-free and overall survival of patients receiving these treatments.
- Assess quality of life in patients receiving these treatments.
OUTLINE: This is a randomized, multicenter study. Patients are randomized to one of two treatment arms.
- Arm I: Patients undergo radiotherapy 3 times daily, with an interval of at least 6 hours between any 2 treatments, 5 days a week, for just over 2 weeks, for a total of 13-14 treatment days.
- Arm II: Patients undergo radiotherapy daily, 5 days a week, for 6-6.5 weeks. Quality of life is assessed at baseline and then annually for 5 years.
Patients are followed every 3 months for 3 years, every 6 months for 2 years, and then annually thereafter.
PROJECTED ACCRUAL: A total of 460 patients (230 per arm) will be accrued for this study within 2-3 years.
