Abstract
Retrospective clinico-statistical observation of 119 cases with malignant tumors in the oral and maxillofacial regions at the dental and oral surgery clinic of the Mie University Hospital during 11 years from 1976 to 1987 was presented.The ratio of male to female was 1. 3: 1. Patients past the age of 70 years ccounted for about 31. 9% and the mean age was 62. 4. Of all cases, 52. 0% were referred by dental practitioners. In 105 cases of primary carcinomas, 96 cases (91.4%) were histologically diagnosed as squamous cell carcinoma, more were involved in the gingiva (34.2%) than in the tongue (25.7). Multiple primary cancers were 5. 8%. Most cases were treated by surgery (S) +chemotherapy (C) or S CA-radiation.The 5-year cumulative survival rate was 60. 9% in the primary oral carcinomas and 61. 3% in the squamous cell carcinoma.It has been suggested that surgery in combination with other treatment is an excellent therapy.
