Continuous hyperfractionated accelerated radiotherapy in locally advanced carcinoma of the head and neck region.

Shortening of the overall duration of radiotherapy would reduce the possibility repopulation of tumor during treatment. Most clinical trials of such accelerated radiotherapy have incorporated a split course to improve normal tissue tolerance. Any interruption, however, even for the week-end, may allow repopulation to occur. A scheme of radiotherapy has been used during which treatment was given 3 times per day on each of 12 consecutive days without interruption for the week-end. In a pilot study a significant improvement in survival and local tumor control has been achieved in 48 patients with head and neck tumors when comparison was made with a previously treated group. A randomized controlled clinical trial is planned.
