Long-term results of radical prostatectomy in clinically localized prostate cancer: experience at the Johns Hopkins Hospital.

Abstract

The objectives of our retrospective long-term analysis of radical prostatectomy at The Johns Hopkins Hospital are to determine the efficacy of radical prostatectomy and the optimal statistical method for ascertaining survival following therapeutic intervention for men with clinically localized prostate cancer. The duration of survival and the cause of death were ascertained for 57 men with clinical stage B1 prostate cancer who had radical prostatectomies at The Johns Hopkins Hospital between 1951 and 1963. The absence of metastatic disease was determined by radiographic survey of the bones only. The survival curve determined by the direct method was virtually identical to the projected survival curve for a 62-year-old man in 1960. The cause-specific actuarial survival analysis indicated that only 14% of the men with stage B1 disease and a 15-year life expectancy will develop metastatic prostate cancer following radical prostatectomy. The cause-specific survival curve plateaued after 10 years, which indicated that the majority of men surviving 10 years free of disease are cured of the disease. Survival analysis was also determined by the direct method for 48 men with clinical stage B2 prostate cancer who had undergone radical prostatectomy between 1951 and 1963. Overall, the survival rates for these men were considerably lower than those for similarly treated men with clinical stage B1 disease. The survival curves following radical prostatectomy for men with stage B1 disease and clinical stage B2 disease pathologically confined to the prostate were similar. Radical prostatectomy for stage B1 disease was performed with minimal morbidity, and potency was preserved in most patients with the use of nerve-sparing modifications.(ABSTRACT TRUNCATED AT 250 WORDS)
