The value of regional lymph node dissection in genitourinary cancer.

Regional lymph node dissection in the management of genitourinary (GU) neoplasms is controversial but is based on a 17 year clinical experience and the achievement of survival figures as good or better than those achieved by any other modality of therapy. Lymphadenectomy has proved to be effective in curing patients with metastatic testicular cancer, renal cell carcinoma and transitional cell carcinoma. Its efficacy in prostate cancer is much less certain and remains largely a staging procedure.
