The extent of lymph node dissection in radical cystectomy is a subject of controversy. A more extended dissection has been reported to be associated with superior survival. We analyzed the relationship between the lymph node count and different causes of death in a sample of 735 patients who underwent radical cystectomy for recurrent or muscle-invasive urothelial or undifferentiated carcinoma of the bladder. The median follow-up was 7.8 yr. The median lymph node count was 17, and the median age was 67 yr. Although there was a clear association between lymph node count and overall survival (?21 vs <10 lymph nodes: 10-yr rates: 59% vs 32%, respectively; hazard ratio: 0.63; 95% confidence interval, 0.46-0.87; log-rank test: p = 0.0056), there was no detectable relationship between…(ver más)
