title: Treatment options after failure of radiation therapy-a review.
abstract: Radioresistant or recurrent prostate cancer represents a serious health risk for approximately 20%-30% of patients treated with primary radiation therapy for clinically localized prostate cancer. The majority of patients exhibit large volume and poorly differentiated disease at the time of diagnosis, which limits the ability of salvage therapy to eradicate the cancer. Early detection with serum PSA monitoring and prostate needle biopsy following primary radiation therapy may identify residual adenocarcinoma at an earlier stage and increase the likelihood of successful salvage therapy. Radical prostatectomy, prostate cryoablation, and brachytherapy comprise the options for salvage treatment available for radiorecurrent prostate cancer. The goal of disease eradication must be balanced against the potential for serious treatment-related side effects. As a result, many patients receive noncurative therapy with androgen ablation despite the real risk of disease progression and mortality.
