[Results of several combination modalities for maxillary cancer]

Two hundred forty-six patients with the histologically proved squamous cell carcinoma of the maxillary sinus were treated at the Department of Radiology, National Sapporo Hospital, with various combined modes of surgery, irradiation and chemotherapy. Four combination modalities were used from 1966 to 1983. One hundred sixty-three (66.3%) patients were men and 83 (33.7%) were women. Five-year survival was 41.0% in T2 (16 cases), 22.3% in T3 (176 cases) and 15% in T4 (53 cases). In 72 cases treated since 1978 with tumor reduction as completely as possible, five-year survival was 43.5%. We recommand tumor reduction as complete as is possible and 40-50 Gy irradiation.
