Exploratory Study of a Novel Based rbcDNA Liquid Biopsy Technique for Colorectal Cancer Early Detection
Study Details
Study Description
Brief Summary
Exploration of a novel rbcDNA liquid biopsy technique for early detection of colorectal cancer is a promising development in the field of disease diagnosis and screening. This technique has the potential to establish an efficient and sensitive system for the early detection of colorectal cancer, which can provide a new perspective for individual health monitoring.

Detailed Description
Patients who are at high risk of developing colorectal cancer and willing to undergo colonoscopy examination will be asked to collect a stool sample prior to bowel preparation for commercially available FIT (fecal immunochemical test) assay, as well as a blood sample for rbcDNA testing. The colonoscopy and histopathologic examination will be used as a reference for the results obtained from these tests.

Outcome Measures
Primary Outcome Measures
- Evaluating the sensitivity, specificity, and accuracy of rbcDNA in colorectal cancer screening [Through study completion,an average of 1 year]
A diagnostic colonoscopy procedure is the reference method. Lesions will be confirmed as malignant by histopathologic examination. The rbcDNA test was deployed to a composite score. The tests were processed independently of colonoscopy procedure.
Secondary Outcome Measures
- Sensitivity of the rbcDNA screening test with comparison to FIT, with respect to advanced adenoma (AA) and CRC [Through study completion,an average of 1 year]
A diagnostic colonoscopy procedure is the reference method. Lesions will be confirmed as malignant by histopathologic examination. The rbcDNA and FIT test were performed.
