Summary

This chapter presents available evidence on several aspects of radiation treatment for men with organ-confined prostate cancer. It addresses a series of focused clinical questions that are addressed in a systematic fashion, including a comprehensive literature search, a rating of the quality of evidence, and an assessment of ratio of benefit and harm of a given treatment option. The clinical questions are: In a patient with localized prostate cancer selecting definitive external beam radiation, what is the optimal dose regimen? and In a patient with localized prostate cancer, is there a benefit with proton beam radiation therapy over photon radiation? The remaining clinical questions are: In a patient with newly diagnosed localized, high-risk prostate cancer, is hormonal therapy indicated as an adjunct to definitive radiation therapy? and In a patient with positive surgical margins, extra-prostatic extension, and/or seminal vesicle involvement after radical prostatectomy, is there a benefit for adjuvant radiation therapy over salvage radiation therapy?
