Radical prostatectomy or radiotherapy in carcinoma of prostate. The dilemma continues.

Evaluation of the efficacy of radical prostatectomy versus radiotherapy in carcinoma of the prostate has been compromised by the scarcity of data in comparable populations. A nationwide search was conducted to compile the available data on the use of radiotherapy in lymphadenectomy-staged patients. The assessed population consists of patients with tumor confined to the gland (Stages A2 and B), negative staging lymphadenectomy, negative bone scan, and normal serum acid phosphatase level who received external beam radiotherapy with curative intent. To provide a broad spectrum of experiences, the search included patients from a large number of institutions including Stanford University, Washington University (St. Louis), those participating in the Radiation Therapy Oncology Group, and a broad range of radiotherapy practices surveyed by the PCS (Patterns of Care Study). A total of 209 patients were identified. No selection criteria other than the aforementioned were applied. The patients were treated consecutively during the survey period. In sharp contradistinction to the reported results of the VA Uro-Oncology Group the analysis indicates a less than 10 per cent probability of progression within the first five years after completion of treatment. Nationwide, the outcome of radiotherapy-treated patients appears to be equivalent to the comparable surgically treated population.
