Clinical Efficacy and Safety of Radical Nephroureterectomy With Versus Without Template Lymph Node Dissection in High-Risk Upper Tract Urothelial Carcinoma: A Multicenter, Prospective, Randomized Controlled Clinical Trial
In Brief
A clinical study evaluating Template Lymph Node Dissection and Selective Lymph Node Resection for Upper Tract Urothelial Carcinoma and Lymph Node Dissection. Currently recruiting, targeting 150 participants across 1 site.
Detailed Summary
The goal of this clinical trial is to learn if adding a template lymph node dissection (TLND) to the standard surgery for upper tract urothelial cancer (UTUC) can improve patient survival and prevent the cancer from recurrence. The main questions it aims to answer are: Do patients who receive standard surgery with LND live longer without their cancer returning? Is adding LND safe, and how does it affect surgery-related complications? Researchers will compare the group receiving standard surgery plus LND to the group receiving standard surgery alone to see if adding LND is more effective. Participants will: Be randomly assigned to one of the two surgical groups. Undergo their assigned surgery and recover in the hospital. Attend regular follow-up visits for checkups and scans for 5 years to monitor for cancer recurrence, with the possibility of long-term follow-up extending to 10 years.

Timeline
Arms & Interventions
Participants in this arm will undergo Radical Nephroureterectomy (RNU) combined with template Lymph Node Dissection (LND). The LND will be performed according to a predefined template based on the primary tumor location: renal hilum+para-aortic (left hilar and paraaortic) or renal hilum+para-caval (right hilar, paracaval, and interaortocaval) for renal pelvis/upper ureter; extended to common/external iliac for mid-ureter; and pelvic (common, external, internal iliac, and obturator) for lower ureter. The surgical approach (open, laparoscopic, or robot-assisted) is at the surgeon's discretion.
Participants in this arm will undergo Radical Nephroureterectomy (RNU) alone. No template lymph node dissection will be performed. However, if intraoperatively identified suspicious and radiographic lymphadenopathy (\>1 cm in the short-axis diameter) are present, they may be removed for pathological staging purposes only.
Interventions
A systematic and anatomic-based lymph node dissection performed during radical nephroureterectomy (RNU) for upper tract urothelial carcinoma (UTUC). The dissection boundaries are strictly defined by a pre-specified template according to the primary tumor location: renal hilum+para-aortic (left hilar and paraaortic) or renal hilum+para-caval (right hilar, paracaval, and interaortocaval) for renal pelvis/upper ureter; extended to common/external iliac for mid-ureter; and pelvic (common, external, internal iliac, and obturator) for lower ureter. The goal is potential therapeutic benefit by removing nodal metastatic disease.
A diagnostic procedure performed during radical nephroureterectomy (RNU). It does not involve a systematic template dissection. The surgeon will only remove intraoperatively identified suspicious and radiographic lymphadenopathy (\>1 cm in the short-axis diameter). The primary goal is pathological staging rather than therapeutic clearance of a nodal basin.
