Lymph Node Dissection Clinical Trial
Official title:
Prospective Randomized Phase II Trial: Comparing the Prognostic Value of Routine Lymphadenectomy Versus Lymphadenectomy Only for Lymph Nodes Enlargement Found in Preoperative Imaging or During Surgery Undergoing Nephroureterectomy in Patients With Primary Upper Tract Urothelial Carcinoma
Recent studies showed the therapeutic benefit of lymphadenectomy in advanced stage urothelial carcinoma of the upper urinary tract, but there is still a lack of prospective studies. Thus, the current guideline recommends lymph node dissection for invasive upper tract urothelial carcinoma (UTUC) on the basis of insufficient evidence. Also, the preoperative judgment of muscle invasive pathological stage T 2+,or N+ is difficult from preoperative imaging. In the investigators' clinical practice, the surgeons performed dissection of regional lymph nodes only in patients with enlargement of lymph nodes found in preoperative imaging or during surgery. The aim of this multi-institutional study was to examine the role of lymphadenectomy in urothelial carcinoma of the upper urinary tract.
