Treatment options in lymph node-positive prostate cancer.

With improved awareness and screening, the incidence of lymph node-positive prostate cancer has declined dramatically over the last 50 years. Stage of cancer, prostate-specific antigen, and grade are risk factors for positive lymph nodes; and those factors, along with the number of involved lymph nodes, are prognostic factors for outcome. Although the numbers have declined, the number of men with lymph node-positive prostate cancer remains significant, and the current challenge is how best to treat these patients. Commonly used treatments include any combination of androgen ablation, surgery, and radiation. There have been a few studies with chemotherapy, and no treatment has been proven superior to the others. Consequently, there remain several reasonable alternatives to treatment, and long-term survival is not unusual. Copyright 2006 American Cancer Society.
