Liquid Biopsy Based Multiomics Study for Colorectal Cancer Early Screening
- Conditions
- Adenomatous PolypsAdvanced AdenomaColorectal CancerAdenoma
- Interventions
- Diagnostic Test: multiomics Colorectal Cancer (CRC) screening test (CRC-Appareo)
- Registration Number
- NCT06258434
- Lead Sponsor
- Sir Run Run Shaw Hospital
- Brief Summary
The primary objective is to determine the diagnostic sensitivity and specificity of the newly developed liquid biopsy based multiomics Colorectal Cancer (CRC) screening test (CRC-Appareo) for detecting advanced neoplasia (including colorectal cancer and advanced adenomas) in high risk patients and patients with confirmed CRC, using colonoscopy as the reference method. The secondary objective is to compare the screening performance of the multiomics Colorectal Cancer (CRC) screening test with commercially available FIT (Fecal Immunochemical Test) assay in detecting advanced neoplasia.
- Detailed Description
The study will be carried out in 5 hospitals throughout China. Patients who are at high risk of developing CRC or confirmed CRC and willing to conduct colonoscopy examination will be asked to collect blood prior to bowl preparation for multiomics CRC screening test which using Reduced Representation Bisulfite Sequencing (RRBS) technology to obtain multidimensional variation information on cell-free DNA (cfDNA) methylation, end sequence, fragment size distribution, and copy number variation in the blood, and integrate analysis through machine learning algorithms to accurately assess the risk of colorectal cancer and advanced adenoma. and will be asked to collect stool sample for commercially available FIT assay. Colonoscopy and histopathologic examination are used as reference. The diagnosis information of each sample was blind to the participants who conduct the multiomics profiling, as well as the informatics who perform the integrate analysis.

- Primary Outcome Measures
Name Time Method Sensitivity and specificity of the multiomics Colorectal Cancer (CRC) screening test (CRC-Appareo) with comparison to colonoscopy Through study completion, an average of 6 months A diagnostic colonoscopy procedure is the reference method. Lesions will be confirmed as malignant by histopathologic examination. The Reduced representation bisulfite sequencing (RRBS) technology to obtain multidimensional variation information on cell-free DNA (cfDNA) methylation, end sequence, fragment size distribution, and copy number variation in the blood, and integrate analysis through machine learning algorithms to accurately assess the risk of colorectal cancer and advanced adenoma. The tests were processed independently of colonoscopy procedure, which was blind to investigators who perform the multiomics profiling and integrate data analysis.
- Secondary Outcome Measures
Name Time Method Sensitivity of the multiomics Colorectal Cancer (CRC) screening test (CRC-Appareo) with comparison to FIT, with respect to advanced adenoma (AA) and CRC Through study completion, an average of 6 months A diagnostic colonoscopy procedure is the reference method. Lesions will be confirmed as malignant by histopathologic examination. The the multiomics Colorectal Cancer (CRC) screening test (CRC-Appareo) and FIT test were performed on the blood and stool sample of the same patient.
