[Clinical and statistical studies on prostatic cancer: prognostic value of clinical stage, Gleason score and age]

We assessed the outcome of 200 patients with prostatic cancer treated at the Public Toyooka Hospital from 1980 to 1989. The patient's age varied from 53 to 94 years (mean 76.8). Overall actuarial survival rate at 5 and 10 years were 52% and 25%, respectively. The 5-year survival according to clinical stage was 69% for stage A, 66% for stage B, 43% for stage C and 32% for stage D disease. A significant difference was noted between the survival of patients with stage A or B and those with stage C or D. Patients with Gleason score of less than 7 showed significantly better survival as compared to those with Gleason score of 7 or more (5-year survival, 64% vs 33%). No significant difference was observed between the survival of patients under the age of 75 and those 75 or older.
