Filter by: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.
The primary objective of the study is to screen multi-omics markers in blood samples and construct a prediction model for CRC based on liquid biopsy, and we will further optimize the prediction model by validating its clinical performance externally.
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.
This study is a clinical validation of our developed a computer-aided optical dignosis of advanced adenoma using non-magnified NBI image. This study is a randomized clinical trial comparing endoscopists' optical recognition of advanced adenoma for sending to histological examination with our computer-aided system. The hypothesis of the study is that the developed computer-aided system increases the percent of sending actual advanced adenoma Intelligence Assisted Optical Diagnosis of Advanced Adenomas
The investigators aim to evaluate the diagnostic accuracy of FIT and the novel panel of four bacterial gene markers collectively named as M3, to detect recurrent advanced adenomas in patients with history of colonic adenomas.
to determine screening value of stool-based SDC2 DNA methylation test for advanced colorectal neoplasia in the asymptomatic Chinese community population.
The primary objective is to determine sensitivity, specificity, positive predictive value and negative predictive value of a bi-target stool DNA testing (the methylation status of SDC2 and SFRP2) for colorectal cancer and advanced precancerous neoplasm(including advanced adenoma and advanced serrated lesions) screening, using colonoscopy as the reference method. Lesions will be confirmed as malignant or precancerous by histopathologic examination. The secondary objective is to compare the performance of the bi-target stool DNA testing to a commercially available fecal immunochemical test (FIT) assay, both with respect to cancer and advanced precancerous neoplasm. Lesions will be confirmed as malignant or precancerous by colonoscopy and histopathologic examination.
The primary objective is to determine the diagnostic sensitivity and specificity of the newly developed multitarget FIT-DNA Colorectal Cancer (CRC) screening test (ColoClear) for detecting advanced neoplasia (including colorectal cancer and advanced adenomas) in high risk patients, using colonoscopy as the reference method. The secondary objective is to compare the screening performance of the multitarget FIT-DNA test with commercially available FIT (Fecal Immunochemical Test) assay in detecting advanced neoplasia.
Colorectal cancer is a common malignant tumor of the digestive tract. It is still a challenging task to detect colorectal cancer at an early stage. Studies have found that DNA methylation has a relationship with the occurrence and development of tumors. Singlera Genomics Inc. has invented the proprietary methyl-Titan sequencing technology and developed a detection method for colorectal cancer and advanced adenoma (Adenoma/Colorectal cancer Early detection, ACE) using the cancer-specific methylation markers. ACE is a blood-based non-invasive diagnostic technique. It has high compliance rate compared with colonoscopy, and sampling is more convenient than stool testing. It also has much higher sensitivity compared to existing blood testing methods. The current study plans to use ACE method to analyze ctDNA in the blood for the cancer-specific DNA methylation markers to aid in the differential diagnosis of patients with colorectal cancer or adenoma. This technique will greatly reduce the discomfort in the diagnosis of suspected patients and improve the diagnosis of high-risk population of colorectal cancer. The goals of this study are: 1) to establish a detection system based on plasma ctDNA methylation sequencing technology for the auxiliary diagnosis of colorectal cancer and adenoma, 2) to assess the diagnostic value of plasma ctDNA methylation signature for colorectal cancer and adenoma, and 3) to assess the association of plasma ctDNA methylation signals with colonoscopy results and pathological results of surgical specimens. A total of 1300 patients (700 cases positive and 600 cases negative) aging between 45 and 80 years old will be enrolled. Colonoscopy will be performed to determine whether patients are positive or negative. Positive patients who need surgical resection will be further classified according to their surgical histopathological results. For negative patients, the type of lesion will be clarified. The plasma samples of all subjects will be analyzed for cancer-specific ctDNA methylation profiles. Based on the results of plasma ctDNA methylation test, the risks of colorectal cancer of the enrolled subjects are scored. Combined with the grouping information, the clinical application value of the cancer-specific methylation profile for early cancer diagnosis will be assessed.
