Hyperfractionated accelerated radiochemotherapy (HFA-RCT) with mitomycin C for advanced head and neck cancer.

To investigate efficacy and feasibility of hyperfractionated accelerated radiotherapy combined with mitomycin C, patients with locally advanced unresectable squamous cell carcinomas of the head and neck region were administered 64-66 Gy in four weeks and mitomycin C (20 mg/m(2)) on day five. Twenty-one consecutive patients were included between November 1997 and June 1999 (median age: 57 years). All tumours were stage T3-4 and 18/21 were N2-3. Eighteen patients experienced grade 3 and three patients grade 2 mucosal toxicity. With median follow up for surviving patients of 42 months, loco-regional control was 55% at three years, overall survival was 33% at three years. This treatment is at the edge of local tolerability, but there is a good curative chance even for very advanced localised tumours, provided a complete remission is induced at primary treatment.
