Post-operative Concurrent Chemo-radiotherapy Versus Post-operative Radiotherapy for Cancer of the Head and Neck

The primary objective of the trial is to determine, in patients who have undergone surgery with curative intent for high-risk CSCC of the head and neck, whether there is a difference in time to loco-regional relapse between patients treated with post-operative concurrent chemo-radiotherapy ,consisting of Carboplatin, and post-operative radiotherapy alone. The target sample size for the trial is 266 patients and will take 3-4 years to accrue, based on an anticipated accrual of 80 patients/year. A further 2 years follow up is required.
