Radical cystectomy with pelvic lymphadenectomy is a gold standard for treatment of muscle-invasive urinary bladder cancer. However, therapeutic and prognostic value of pelvic lymphadenectomy is still controversial. Recent studies have demonstrated a better prognosis after extended lymphadenectomy. A multicenter study was made to standardize an extended lymphadenectomy procedure. We examined prospectively the total number of lymph nodes removed from various sites, number and location of positive nodes and its relation to location of primary tumors in the urinary bladder. Thirty five radical cystectomies with extended lymphadenectomy were performed for the treatment of invasive bladder cancer in National Urology Center in 1999-2004. The margins of extended lymphadenectomy were: cranial level of a.mesenterica inferior; lateral--n.n. genitofemoralis; caudal-fossa obturatoria. A total amount of removed lymph nodes comprised 1081, mean 34.2 +/- 8.1 lymph node per patient (range from 10 to 58). Fourteen patients (40.0%) were node positive (69 nodes). According to N category: N1--6 patients; N2--7 patients. Six patients had lymph node metastases up to the aortic bifurcation. In 6 cases a positive node was found on the contralateral side. Thus, we recommend extended radical lymphadenectomy for all patients undergoing radical cystectomy for bladder cancer.
