Noninvasive Early Diagnosis of Colorectal Cancer Using Odor-Targeted Capture, Point-of-Care Testing, and Intelligent Analysis
Sponsor: Beijing University of Chinese Medicine
Summary
The goal of this observational study is to see whether a new, noninvasive test that analyzes smells (odor) from breath and intestinal gas can help detect colorectal cancer and precancerous growths at an early stage. The main questions it aims to answer are: Can the new odor-based test correctly identify people who have colorectal cancer or precancerous lesions? How accurate is the new test compared to the current standard method (colonoscopy with biopsy)? Researchers will compare the results of the new test with standard diagnostic results. Participants will be asked to: Provide samples of breath, urine, stool, and intestinal gas (collected using a special device or a collection bag) Allow researchers to review their medical records and colonoscopy results Answer questions about their health history and lifestyle This study involves no treatments or procedures beyond normal medical care. It only collects samples and data for research purposes.
