Read our Colorectal Cancer research guide →This is a research study that collects blood and tissue samples from patients undergoing surgery for stomach cancer, colon cancer, or non-cancerous digestive conditions like ulcers or inflammatory bowel disease. The samples—along with information about your health—will be stored safely and made available to researchers studying these conditions. The goal is to build a resource that can help scientists understand these diseases and develop better treatments.
Researchers need access to real tissue and blood samples from patients to study how cancer and digestive diseases develop and progress. By collecting and storing these samples with medical information, scientists can conduct current and future research that may lead to better understanding and treatment of these conditions.

You likely don't qualify if…
If you qualify, you would donate blood samples and allow doctors to collect tissue samples during your already-planned surgery. The samples are stored securely along with information about your medical history and diagnosis. You would not need additional visits or procedures beyond your scheduled surgery—the sample collection happens as part of your surgical care.
