Surveillance strategies for renal cell carcinoma patients following nephrectomy

Renal cell carcinoma (RCC) is the most lethal of urologic malignancies, accounting for an estimated 36,000 new cases of carcinoma and 12,000 deaths in 2005. Nephrectomy is the usual treatment; however, after nephrectomy, RCC recurs in 20% to 40% of patients with clinically localized disease. A consensus surveillance protocol does not exist for follow-up of RCC after nephrectomy. In this article, available protocols are reviewed with a goal of developing an evidence-based system including the prognostic factors for recurrent disease, chronology and sites of recurrence, available treatment options if recurrent disease is found, and modalities of diagnostic testing available to urologists. New surveillance recommendations are presented based on prognostic factors as well as the University of California, Los Angeles Integrated Staging System for RCC.
