The role of lymphadenectomy in patients undergoing radical cystectomy for bladder cancer.
The role of regional lymph node dissection (LND) in surgical management of high-grade, invasive transitional cell carcinoma of the bladder has evolved over the past several decades. The current concepts and rationale for LND in patients undergoing radical cystectomy for bladder cancer are reviewed and discussed. Evidence suggests that a more extended LND (with cephalad extent to include at least the common iliac vessels) for lymph node-positive and -negative patients undergoing radical cystectomy for bladder cancer may provide therapeutic benefits in addition to prognostic information. Lymph node density also provides risk stratification for lymph node-positive patients and may reduce the surgical bias and extent of the LND, both of which are currently not standardized. Although the absolute limits of the LND remain to be determined, an evolving body of data supports a more extended LND at the time of cystectomy in appropriate surgical candidates.
