A retrospective review of 124 patients of carcinoma of the maxillary sinus treated at Kurume University Hospital from 1971 to 1980 was completed. Of these 124 patients, 111 patients had not been previously treated and underwent curative treatment, 8 patients underwent palliative treatment, and 5 patients were those who had been previously treated at other clinics. The results of this retrospective studies are summarized as follows: 1) In the 58 patients who were followed up for 5 years or more after the onset of initial curative treatment, the 3- and 5-year crude survival rates calculated by direct method were 58.6% and 51.7%, respectively. 2) In the 111 patients who underwent curative treatments, the 3- and 5-year cumulative survival rates calculated by the actuarial method were 61.8% and 52.3%, respectively. 3) Among various factors which can be determined before the treatment, T category and L. V. histological classification were considered to be useful in order to estimate the prognosis. 4) With respect to T categorization, the JJC proposal proved to be better than the A JC proposal. 5) The majority of causes of deaths was uncontrolled primary lesion. Involvement of the cervical lymph nodes were controlled in most cases and distant metastasis were not frequent. 6) As for the treatments, the best modalities appeared to be the following two combinations: (1) infusion, radiation and necrotomy followed by an eradicating surgery and (2) infusion, radiation and necrotomy associated with a mass reduction surgery. 7) Three year crude survival rate calculated by direct method was equally 80.0% in the above two combination therapies. Final conclusions on the comparison between these two Combination treatments await further followup studies of more patients.
