Contrast-enhanced CT-based Deep Learning Model for Preoperative Prediction of Disease-free Survival (DFS) in Localized Clear Cell Renal Cell Carcinoma (ccRCC)

This study is building and testing a computer (deep learning) model that uses CT scan images taken before surgery to predict how long a patient with clear cell kidney cancer (ccRCC) will remain disease-free after their tumor is removed. The goal is to help doctors better identify who might be at risk for cancer returning. **You may be eligible if...** - You had surgery (partial or complete kidney removal) for kidney cancer - Your cancer was confirmed as clear cell renal cell carcinoma (ccRCC) by pathology - You have complete medical records and pre-surgery CT scan images available **You may NOT be eligible if...** - Your medical or scan records are incomplete - You had chemotherapy or targeted therapy before or after surgery - You had multiple kidney tumors at the same time or cancer that had already spread - Your CT image quality is too poor for analysis Talk to your doctor to see if this trial is right for you.
