Eighty-seven cases of carcinoma of the maxillary sinus, treated from 1969 to 1978 at Hiroshima University Hospital, were investigated clinically.The following results and conclusions were obtained: [1] Men were affected more frequently than women, in a ratio of 1.7:1. The greatest incidence was in the 50- to 60-year age groups. [2] Histologically, squamous cell carcinoma was by far the most common malignant tumor. [3] All cases, excluding two malignant lymphomas, were classified based on TNM system. The results were: T1, 1; T2, 19; T3, 59; T4, 6. The incidence of cervical metastasis was rather small (13%). [4] Overall three- and five-year survival rates were 40.0% and 31.6% respectively. Three- and five-year rates by stage were: T1+2, 53.3% and 43.7%; T3, 36.6% and 26.8%; T4, 0% and 0%. [5] The most successful treatment was a combined therapy consisting of local chemotherapy, radiation and necrotomy, followed by radical surgery. Three- and five-year survival rates for this treatment were 56.3% and 43.8% respectively.
