Radiation, pepleomycin and hyperthermia in the therapy of locally advanced squamous cell carcinomas of the buccal mucosa.
Oral squamous cell carcinoma is the commonest male (29%) and the second commonest female (18%) malignancy in South India. At first attendance 93% of the tumours are stage T3 or T4. They are essentially locoregional, remote metastases being rare (0.75%). Radiotherapy alone yields a poor survival (19% 5 year NED). Radiopotentiation by chemical sensitizers and cytotoxic drugs has been attempted since 1960, the best results being obtained by a combination of irradiation and bleomycin. There was, however, persistent failure in about 40% of cases. The present three-armed trial attempted to improve the results of radiotherapy and bleomycin by the addition of hyperthermia. A total of 101 T3 and T4 buccal squamous cancers were entered in the trial over a period of nearly three years. Entry closed in August 1987 and the last case was evaluated in October 1987, hence only response data are available. Hyperthermia did not confer any benefit.
