Radiation therapy for prostate cancer: external beam, brachytherapy, and salvage.
Radiation is a curative treatment for prostate cancer that is most appropriate for the older patient or the patient with significant co-morbidities. Younger patients with a greater than ten-year survival are probably best treated with surgery unless the disease is high risk. For all patients, high-risk disease is best treated with hormones and radiation. The long-term superiority of surgery over radiation, however, has not been demonstrated in randomized or retrospective studies, and the recommendation for surgery in the younger, healthy patient with favorable local disease is largely based on theoretical considerations. If chosen for appropriate indications and delivered with appropriate techniques, radiation can be delivered using external beam or brachytherapy with equal efficacy. The choice of radiation treatment is based on tumor characteristics and patient preference. Radiation can be used after prostatectomy to cure patients who are not cured with surgery. Watchful waiting may be appropriate for patients with low-risk disease.
