Brief summary
To evaluate the accuracy and effectiveness of a novel screening method based on plasma multi-omics combining with artificial intelligence in a large prospective cohort for the detection of colorectal cancer and advanced adenomas.
Detailed description
Minimally invasive detection of circulating tumor DNA (ctDNA) in peripheral blood of patients with colorectal malignancies via liquid biopsy has emerged as a promising biomarker. This is urgently needed, as conventional imaging and plasma protein-derived biomarkers lack sensitivity and specificity.The goal of this observational study is to evaluate the effectiveness and accuracy of a novel screening method based on plasma multi-omics combining with artificial intelligence in five hospitals around China for the detection of colorectal cancer and advanced adenomas.
Interventions
Colonoscopy is performed to identify whether the patient has colorectal adenoma or cancer
A specified panel is used to detect the site of methylation of ctDNA in plasma
Low pass whole genome sequencing is used to detect the characteristics of ctDNA fragment

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Sensitivity | Through study completion, an average of 1 year | Sensitivity (for colorectal cancer and\\or advanced precancerous neoplasm) of this plasm-based multi-omics test. The diagnostic colonoscopy procedure is reference method. Lesions will be confirmed as malignancy or precancerous by pathological biopsy. |
| Specificity | Through study completion, an average of 1 year | Specificity (for colorectal cancer and\\or advanced precancerous neoplasm) of this plasm-based multi-omics test. The diagnostic colonoscopy procedure is reference method. Lesions will be confirmed as malignancy or precancerous by pathological biopsy. |
