Template Lymph Node Dissection for Tumor Control in High-Risk Renal Cell Carcinoma: A Prospective, Open-Label, Multicenter, Randomized Controlled Trial
In Brief
A clinical study evaluating Template Lymph Node Dissection and Selective Lymph Node Resection for Renal Cell Carcinoma (Kidney Cancer). Currently recruiting, targeting 220 participants across 1 site.
Detailed Summary
The goal of this clinical trial is to learn if a more thorough lymph node removal surgery, called "Template Lymph Node Dissection," can help prevent cancer from returning and help patients live longer, compared to removing only a few enlarged lymph nodes, in patients with high-risk kidney cancer. The main questions it aims to answer are: Do patients who receive template lymph node dissection live longer without their cancer returning (Disease-Free Survival)? Do patients who receive template lymph node dissection live longer overall (Overall Survival)? Is the more extensive lymph node surgery as safe as the limited surgery? Researchers will compare the Template Lymph Node Dissection group to the Limited Node Resection group to see the effects on cancer control and safety. Participants will: Be randomly assigned to one of the two surgical groups. Undergo surgery to remove their kidney and the assigned lymph nodes. Attend regular follow-up visits with imaging scans (like CT or MRI) for the first 5 years after surgery to monitor if the cancer returns. Be followed for their overall survival status for up to 10 years.

Timeline
Arms & Interventions
Patients randomized to this arm will undergo radical nephrectomy (which may be performed via open, laparoscopic, or robot-assisted approach based on the surgeon's expertise) combined with a standardized template lymph node dissection. The template lymph node dissection is defined as follows: For Left-sided Tumors: Removal of lymphatic tissue anterior and lateral to the abdominal aorta, extending from the diaphragmatic crus superiorly to the aortic bifurcation inferiorly, including the renal hilar lymph tissue. For Right-sided Tumors: Removal of lymphatic tissue surrounding the inferior vena cava and in the interaortocaval space, extending from the liver edge of the vena cava superiorly to the iliac vein bifurcation inferiorly, including the renal hilar lymph tissue.
Patients randomized to this arm will undergo radical nephrectomy (which may be performed via open, laparoscopic, or robot-assisted approach). In this arm, only lymph nodes that are identified as \>1 cm in the short axis on preoperative cross-sectional imaging (CT/MRI) OR are grossly enlarged and suspicious during the surgeon's intraoperative assessment will be resected. If no such nodes are identified preoperatively or intraoperatively, no formal lymph node dissection is performed.
Interventions
A standardized surgical procedure to remove lymph nodes within defined anatomical boundaries during radical nephrectomy for kidney cancer. For left-sided tumors, this includes tissue anterior and lateral to the aorta from the diaphragmatic crus to the aortic bifurcation. For right-sided tumors, it includes tissue around the vena cava and between the vena cava and aorta from the liver edge to the iliac bifurcation. The renal hilar lymph tissue is always included.
A surgical approach during radical nephrectomy for kidney cancer where lymph nodes are removed only if they meet specific criteria: being larger than 1 cm on preoperative CT/MRI scans, or appearing grossly enlarged and suspicious to the surgeon during the operation. If no such nodes are identified, no lymph node dissection is performed.
