Selecting treatment for high-risk, localized prostate cancer: the case for radiation therapy.

Abstract

Prostate cancers that clinically appear to be localized may nonetheless respond poorly to curative treatment. Pretreatment prostate-specific antigen (PSA) level, biopsy Gleason score, and percentage of positive biopsies are all at least as important as clinical stage in predicting treatment outcome. A patient with a nonpalpable tumor, stage T1c disease, serum PSA of 12 ng/mL, and a Gleason score of 8 to 10 in 2 of 12 biopsy cores has a relatively poor prognosis. In a high-risk patient such as this one, the recommended treatment strategy involves a combination of brachytherapy and conformal external beam radiotherapy. In studies comparing treatments in patients stratified according to a variety of risk measures, this combination has shown biochemical disease-free survival rates superior to those seen following radical prostatectomy. The role of androgen suppression remains unclear.
