AI-Assisted Detection and Staging of Gastric Cancer Using Contrast-Enhanced CT

This study uses artificial intelligence (AI) to analyze CT scan images of stomach cancer patients to improve how accurately the cancer is detected and staged (how far it has spread) before surgery. It compares the AI findings to the actual surgical pathology results. No experimental treatment is involved. **You may be eligible if...** - You have a confirmed diagnosis of stomach (gastric) cancer - You had a contrast-enhanced CT scan before surgery - There was no sign of distant spread of cancer at the time of diagnosis - You received surgery with intent to cure and complete tissue analysis was done afterward **You may NOT be eligible if...** - You received any treatment (chemotherapy, radiation, etc.) before surgery - Your CT scan was of poor quality or could not be evaluated Talk to your doctor to see if this trial is right for you.
