[Clinical studies of newly diagnosed prostate cancer].
BACKGROUND
The objective of this study is to report the outcome of various treatments in patients who were newly diagnosed prostate cancer from May 1984 to December 1994, at a single institution.


METHODS
A retrospective study was carried out in the 142 patients.


RESULTS
Total retropubic prostatectomy were performed in 52 patients (37%). The 5-year survival rates (Kaplan-Meier) in the patients with total prostatectomy were 89% in stage B (24), 86% in stage C (7), and 87% in stage D1 (17), respectively. Endocrine therapies (33) or endocrine therapies in combination with chemotherapies (37) as a initial therapy for stage D2 were performed. Among these therapies, endocrine therapy in combination with cyclophosphamide (700 mg/m2/4 weeks, i.v.) was superior to any of the other treatments in stage D2. The response rate, median response duration and median survival time in this combination therapy were 83%, 29 months and 49 months. The overall 3, 5, and 10-year survival rate in the 142 patients were 67%, 51% and 26%, respectively. The 5-year survival rates according to grade were 73% in grade 1, 45% in grade 2, 42% in grade 3, respectively.


CONCLUSIONS
The 5-year survival rates in pathological stage C and D1 patients who received adjuvant hormone and radiation therapy after radical prostatectomy were 86% and 87%. The most effective therapy for stage D2 was hormone in combination with cyclophosphamide. The response rate and median response duration were 83% and 29 months.
