Objective:
[corrected] To assess the usefulness of pelvic lymphadenectomy in bladder cancer.
Methods And Results:
With the followings key words: "bladder cancer, lymphadenectomy, lymph node metastasis" we search in Medline/PubMed database for papers published during the last ten years. Thirty three papers fulfilling the search criteria were selected.
Conclusions:
It does not exist any randomized prospective study comparing different pelvic lymphadenectomy techniques. Nodal metastasis in bladder cancer after radical cystectomy and pelvic lymphadenectomy ranged between 18% and 28%. Standard lymphadenectomy could improve tumor staging and probably survival in selected patients. It is advisable to remove, as a quality parameter, at least 10 to 14 nodes in a pelvic lymphadenectomy. Lymph node density seems to predict survival better than TNM staging system. It is advisable to perform separate lymph node dissection rather than en-bloc.
