[Pre-irradiation and surgery of patients with squamous cell carcinoma of the oral cavity and oropharynx: the results of a 1973-1984 study].
In collaboration with the Radiotherapeutic Hospital, 87 patients with squamous cell carcinomas of the oral cavity and the oropharynx were treated by combined pre-irradiation and surgical intervention at the University ORL Hospital of Cologne. The study was supposed to improve the five-year survival of patients suffering from advanced carcinomas of the head and neck area. The male and female patient's ratio was 4.5 to 1. Half of the patients had squamous cell carcinomas of the oropharynx, 21 patients had tumors of the floor of the mouth, and another 21 had tumors of the anterior two thirds of the tongue. The tumor and lymph node status was classified according to the UICC regulations (1979). In the pre-irradiation, 40 to 50 Gy were applied to the primary tumor and the regional lymph nodes. Surgery was executed generally four weeks after pre-irradiation. The tumor remission following to pre-irradiation was very good. 27% of the patients showed little or moderate post-operative disturbances in wound healing. An osteoradionecrosis was found in 4.6%. Almost 25% of the patients developed local recurrences. The cumulated five-year survival of all patients is 32%. In dependence on TNM stages, the three-year survival rates are as follows: stage I and II 80%, stage III 44%, and stage IV 40%.
