Role of lymphadenectomy for invasive bladder cancer.
Radical cystectomy with lymph node dissection remains the standard of care in the treatment of muscle-invasive and refractory non-invasive bladder cancer. Over the past decade, the extent of lymphadenectomy has varied to include dissection up to the common iliac vessels and aortic bifurcation proximally (may also extend up to the level of the inferior mesenteric artery), the genitofemoral nerve laterally, the circumflex iliac vein and lymph node of Cloquet distally, and the hypogastric vessels posteriorly (obturator fossa, presciatic nodes bilaterally and the presacral lymph nodes over the sacral promontory). Evidence supports the role of lymphadenectomy as both a therapeutic and prognostic variable in patients with invasive bladder cancer. We review the literature regarding the role and extent of lymphadenectomy, as well as its impact on patient outcomes.
