External-beam radiotherapy (EBRT) has been used in the treatment of adenocarcinoma of the prostate gland for more than 30 years. Well-documented clinical series have demonstrated the effectiveness of EBRT in achieving both cause-specific survival and freedom from biochemical (prostate-specific antigen [PSA]) progression. Methods: The indications and expected treatment results for treatment by EBRT in the management of adenocarcinoma of the prostate gland are reviewed. The treatment of

In the management of locally advanced disease, the use of EBRT with combined androgen ablation is discussed as definitive therapy and also as indicated in the postoperative adjuvant management of surgically identified pathologic stage T3 disease. Results: The relative clinical benefit of EBRT compared with the mostly predictable and well-defined moderate side effects, which are manageable in most instances by conservative measures treatment, is well established. Advances in defining radiation-beam parameters have led to more effective and safer treatment for prostate cancer. Conclusions: EBRT has historically been a mainstay in the management of prostate cancer. It remains a useful and indicated treatment modality in patients with early-stage, locally advanced, and metastatic disease. Technological advances in external-beam radiation therapy and the developments in equipment and computers allow for safer delivery of higher radiation doses to the prostate. Tina Sotis.
