Thirty patients with adenocarcinoma of the prostate, Grade III-V, Stage IV, 80 years of age or more have been studied. Survival rate at 12 months was 19/30 (63.3%). Survival rate at 3 years was 18/30 (60%). The results of this study show that in spite of being a selected group of patients with high grade, high stage tumors, the survival rate at three years was even better when compared to a heterogeneous group of patients ten years younger (57.75%).
