Eingeschränkte vs Ausgedehnte Lymphadenektomie LEA

Status Completed

Clinical Trial Summary

This trial evaluates the therapeutic benefit of extended versus limited lymphadenectomy at the time of radical cystectomy in patients with bladder cancer.

Clinical Trial Description

The extent of pelvic lymphadenectomy in the surgical treatment of muscle-invasive, clinically locally bladder cancer is not yet standardized. There are no data from randomized, prospective studies on the prognostic role of regional lymphadenectomy.

Results of retrospective studies suggest, that the prognosis of patients with muscle-invasive bladder cancer can be improved by extending the limits of pelvic lymphadenectomy. Furthermore it could be demonstrated in a prospective study that the pattern of metastasis of bladder cancer has a high variability. About two-thirds of lymph node metastases are found outside the normally cleared areas of lymphadenectomy. In this study patients will be randomized into arms with limited versus extended lymphadenectomy.

The limited lymphadenectomy includes the removal of the obturatoric, external and internal iliac lymph nodes, the extended one includes the removal of all lymph nodes between pelvic floor and the inferior mesenteric artery. The primary objective of the study is to detemine the influence of limited versus extended lyphadenectomy at the time of radical cystectomy on recurrence-free survival. Secondary study objectives include the influence on cancer-specific survival, overall survival, complication rates, histopathologic N-stage, the localization of recurrence and influence of adjuvant chemotherapy . Adjuvant chemotherapy is optional and is recommended in patients with locally advanced disease (pT3/4) or regional lymph node metastasis (pN+). ;
