Researchers want to learn how common confusion and thinking problems are after surgery for stomach or esophageal cancer. This observational study will track your brain function at several time points—before chemotherapy (if you receive it), before surgery, and after surgery—to understand what factors might affect your recovery and quality of life.
After major surgery, some patients experience confusion or difficulty thinking clearly, but doctors don't fully understand how often this happens with cancer surgery or what factors make it more likely. This study aims to fill that gap so that surgical teams can better prepare and support patients.

You will complete brief thinking and memory tests at key points in your cancer journey: before chemotherapy (if applicable), when you arrive for surgery, and on days 1, 3, and 7 after surgery, plus again 4–8 weeks later. You'll also fill out questionnaires about your quality of life, mood, and nutrition. If you experience confusion after surgery, you may be asked to share your experience in a conversation with a researcher to help them better understand what that was like for you.
