Abstract
From November 1985 until October 1988, 39 patients with head and neck carcinoma (6 patients stage I-II and 33 stage III-IV) were treated with an accelerated radiotherapy schedule designed to deliver 69.6 Gy over a period of 5 weeks. Treatment was started with 20 Gy in 10 daily fractions to sites of initial macroscopic involvement, followed by bi-fractionated radiotherapy (2 x 1.6 Gy/day) to a larger head and neck volume. Twenty patients received neo-adjuvant chemotherapy. A homolateral radical neck dissection was performed in 2 patients. Twenty-six patients (66.6%) presented with acute grade 3 complications and 5 patients (13%) with grade 4 complications. Thirteen patients (33.3%) were hospitalized for supportive care. None of the patients who were evaluated on a long-term basis developed grade 3 or 4 late complications. The 5-year loco-regional control and overall survival rates were 62.4% and 33.6% respectively. Although acute toxicity is higher than in monofractionated schedules, it is manageable, and can be considered acceptable in the light of the apparently good loco-regional control thus obtained. This schedule is one of several accelerated radiotherapy programs which might merit study in prospective trials.
