Abstract
The application of some basic principles derived from studies of the cell cycle and proliferative kinetics of normal and malignant cells has provided a rational basis for designing cancer treatment protocols. Using this approach in advanced head and neck cancer it is possible (a) to increase the response rate, (b) to reduce toxicity and (c) to reduce in‐patient hospital stay time. Seventy‐one patients with advanced carcinoma of the head and neck were randomized for treatment between two combination schedules, one with and the other without adriamycin. Responses (more than 50% tumour regression) were 74% overall with 70% responding to the combination without adriamycin and 82% responding to the schedule containing it. The increase in response rate seen with adriamycin is not statistically significant. Prior radiotherapy significantly reduced the likelihood of response to chemotherapy. These results have major implications for adjuvant chemotherapy and suggest a possible way of increasing the survival time in this group of diseases.
