[Effect of tegafur administration combined with hormonal therapy in patients with newly diagnosed stage D prostatic cancer].
To study the effect of tegafur administration combined with hormonal therapy on the survival rate of newly diagnosed patients with stage D prostatic cancer, 66 patients, 70.9 years old in mean age, were treated from 1979 to 1986. The cancer was proven by the histological or cytological examination of the specimen which was obtained by the needle biopsy and/or aspiration biopsy of the prostate. The histopathological diagnosis of 59 patients was as follows: well differentiated type of adenocarcinoma was observed in 13 patients, moderately differentiated type in 19 cases, poorly differentiated type in 24 cases and mixed type in 3 cases. Daily 600 mg tegafur was administered orally as long as possible from the beginning of the treatment combined with hormonal therapy. Actual and relative 5 year survival rates calculated with Kaplan-Meier's method were 31.2% and 39.2%, respectively. When deaths other than prostatic cancer death were counted as lost cases, the actual survival rate was 47.5%. The present study also demonstrated that there were some factors affecting the patients' prognosis. They were the age of onset of the disease (patients under 64 years old were worse than those over 65 years old; p less than 0.05), performance status (patients with PS from 0 to 2 at the first admission were better than those with PS 3 to 4; p less than 0.025), differentiation of the tumor (well differentiated type was better than moderately; p less than 0.025 or poorly differentiated type; p less than 0.005).
