Noninvasive Early Diagnosis of Colorectal Cancer Using Odor-Targeted Capture, Point-of-Care Testing, and Intelligent Analysis
Key Technology Research on Non-invasive Early Diagnosis of Colorectal Cancer Based on Odor-targeted Capture, Instant Detection, and Intelligent Analysis
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.

Studie Bevolking
The study population will consist of three groups recruited primarily from Beijing University of Chinese Medicine, Dongfang Hospital：
Patients with histopathologically confirmed colorectal cancer (TNM stage I-IV).
Patients with histopathologically confirmed precancerous lesions (e.g., colorectal adenomas, sessile serrated lesions).
Healthy controls with no abnormalities on colonoscopy within the past year and no history of colorectal cancer or other malignancies.
Participants will be adults aged 18 to 85 years. Healthy controls will be recruited from the same hospital settings and matched for key demographic factors (age, sex, BMI) and lifestyle habits to minimize confounding.
