前立腺癌の臨床統計的観察

Abstract

Clinical observations on prostatic cancer were studied in 27 patients who had been managed in our department between April, 1980 and December, 1986. The mean age at the time of initial clinical visit was 70.6 years old with a range of 55 to 88 years old. Of all 27 patients, 15 men (55.6%) were senior citizens over 70 years old and indeed 23 men (85.2%) were over 60 years old. According to the general rules for clinical and pathological studies on prostatic cancer, there were 10 patients with stage A, 2 patients with stage B, and 15 patients with stage D disease. However, none of our patients had stage C foci of prostatic cancer. Histopathologically, biopsied or surgically resected specimen all showed adenocarcinoma. More frequently the incidence of poorly differentiated adenocarcinoma was found in the specimen from the patients with advanced clinical disease. Anti-androgen therapy with castration or a combined hormonal manipulation initially was done in 25 patients. Simple hormonal treatment using chlormadinone acetate (CMA) was given in 13 patients. Of 25 patients who received hormone treatment, 22 underwent castration whereas, 12 of 13 having undergone single hormonal therapy were castrated. Combined chemohormonal therapy using UFT and CMA or additionally given estramustine phosphate disodium (Estracyt) was subjected only to stage D disease of prostatic cancer. Of 15 patients surgically treated, 11 received transurethral resection of the prostate on the basis of initial diagnosis of benign prostate hypertrophy.(ABSTRACT TRUNCATED AT 250 WORDS)
