Abstract

216 patients with malignant neoplasms in the oral and maxillofacial region were retrospectively studied. All patients were treated in the Department of Oral and Maxillofacial Surgery, Kyoto University Hospital during the 10 year period from 1973 to 1982.
In 204 cases of the carcinomas, 89.2% were pathologically diagnosed as squamous cell carcinoma, most sited on the gingiva. More than 70% of the carcinomas in oral cavity were clinically advanced cases (stage III or IV), most cases were treated by surgery (S) +irradiation (R) +chemotherapy (C) or by surgery in combination with irradiation therapy.
The 5 year survival rate in each combination therapy was 72. 4%(S+R+C), 77%(S+R), 30%(R+C), and the over all 5 year survival rate was 55.7%.
