ObjectiveTo compare extended pelvic lymph node dissection (ePLND) with non-extended pelvic lymph node dissection (non-ePLND) and assess their influence on recurrence-free survival (RFS) in patients undergoing radical cystectomy for bladder cancer.MethodsThrough a comprehensive search of the PubMed, Embase and Cochrane Library databases in September 2012, we performed a systematic review and cumulative meta-analysis of all comparative studies assessing the extent of pelvic lymph node dissection (PLND) and its influence on RFS.ResultsSix studies with a total of 2824 patients were identified.Overall analysis showed a significantly better RFS rate in patients who had undergone ePLND than in those who had undergone non-ePLND (hazard ratio [HR]: 0.65; P < 0.001).A subgroup analysis found that, compared with non-ePLND, ePLND was associated with a better RFS rate for both patients with negative lymph nodes (HR: 0.68; P = 0.007) and those with positive lymph nodes (HR: 0.58; P < 0.001). When stratified by pathological T stage, ePLND provided additional RFS benefits for patients with pT3-4 disease (HR: 0.61; P < 0.001), but not for patients with
