Radical Nephrectomy With vs Without Template Lymph Node Dissection in High-Risk Renal Cell Carcinoma (T-LND RCC)

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.
