The article by Stock provides a comparison of outcomes following radiation therapy and radical prostatectomy in men with clinically localized prostate cancer. The reliability of this comparison is complicated by the lack of randomized trials and the obvious selection biases inherent in uncontrolled studies. Ultimately, however, the value of either therapy depends critically on the difference between radiation or surgery and watchful waiting--an issue that is not addressed in this article.
