[Clinical study on adenocarcinoma of the prostate].
In 92 patients with prostatic carcinoma who were treated at the Takamatsu Red Cross Hospital from January 1976 to December 1985, we analyzed the age, chief complaint, degree of advancement, grade of tumor, way of therapy and prognosis. The age of the patients was between 51 and 87 years (mean: 74.8 years). The most frequent chief complaint was dysuria. In terms of the degree of advancement, 14 cases were assessed as Stage A, 23 cases as Stage B, 16 as Stage C and 39 as Stage D. Analysis of the grade of tumor disclosed that 38 cases (41.3%) had well differentiated adenocarcinoma, 20 cases (21.7%) had moderately differentiated adenocarcinoma and 29 cases (31.5%) poorly differentiated adenocarcinoma. Forty-four of the subjects have already died. The 5-year survival rate was 41.2% when calculated pursuant to life table method. The 5-year survival rate was 85.7% for Stage A, 36.1% for Stage B, 53.4% for Stage C and 24.3% for Stage D. The 5-year survival rate was 54.7% for well differentiated adenocarcinoma, 61.7% for moderately differentiated adenocarcinoma and 12.7% for poorly differentiated adenocarcinoma. Comparison of the 3-year survival rate among the 4 ways of therapy revealed only a small intergroup difference; namely, the rate was 58.5% for hormone therapy, 51.6% for intraarterial neocarzinostatin therapy, 77.1% for total prostatectomy and 57.1% for radiation therapy. These results indicate that our way of chemotherapy, which chiefly employs intraarterial administration of neocarzinostatin as an induction therapy, is at least comparable or superior to hormone therapy in terms of efficacy.
