Sample Collection Study for Patients Undergoing Surgery for Colorectal Cancer, Gastric Cancer, or Non-cancerous Gastrointestinal Diseases

What this Trial Is About

Researchers are collecting and storing samples such as blood, normal tissue, and tumor tissue from patients diagnosed with colorectal cancer or gastric cancer. They are also gathering samples from patients with non-malignant gastrointestinal diseases like inflammatory bowel disease, gastric ulcer, hemorrhoids, or hernia. The goal is to create a database that links these samples with clinical information for use in current and future research protocols. Samples are collected during scheduled surgeries that patients are already undergoing as part of their usual care. There is no additional intervention or treatment given as part of this study, so the study does not change the patients medical care. Patients are grouped based on whether they have colorectal or gastric cancer or non-malignant disease. Participants will provide informed consent before joining the study. The collected samples and clinical data will be confirmed by a pathologist over up to three years. The study involves no extra treatments or procedures beyond the scheduled surgery. Participation lasts through the surgical procedure and sample collection, with ongoing data review and storage for future research. The study runs until December 2026.
