Abstract
Whole pelvic radiotherapy (WPRT) is controversial in the management of prostate cancer. The estimation of the risk of pelvic lymph node involvement in prostate cancer patients will identify those who will potentially benefit from WPRT. Nomograms and equations based on pretreatment prostate-specific antigen (PSA), Gleason score, and/or clinical stage allow clinicians to quickly estimate nodal risk. Most of the studies analyzing WPRT, including a randomized trial from the Radiation Therapy Oncology Group (RTOG), were conducted in the pre-PSA era and did not necessarily include patients at high risk for nodal involvement. The addition of hormonal therapy to WPRT has been shown in 4 major prospective randomized trials to improve survival for some subsets of patients. The preliminary results of RTOG 94-13 show the superiority of WPRT over prostate-only radiotherapy (PORT) in high-risk prostate cancer patients receiving hormonal therapy. For most other solid tumors, the regional lymph nodes are routinely treated by some modality, so it is not surprising that WPRT might benefit a subset of high-risk patients. © 2003 Elsevier Inc.
