Overview
This study is designed to prospectively collect blood samples and clinical data from patients that have been newly diagnosed with colorectal cancer and scheduled for resection surgery but are pre cancer treatment, subjects who are NOT scheduled for surgery but have histological confirmation of CRC from the diagnostic colonoscopy and clinical staging (cTMN) is available and are pr e- treatment, and patients who are at average risk of colorectal cancer and who are scheduled for routine colonoscopy examinations.
Description
The Sponsor has identified cfDNA (circulating free-DNA) alterations (including methylation, fragmentation, and copy-number variance) that allow specific detection of colorectal cancer (CRC) advanced precancerous lesions (APL) and is in the process of developing a bloodbased test for early detection of colorectal cancer. The Sponsor is performing the current study to evaluate and optimize the performance of a preliminary panel of markers to finalize the assay for the use for US population. This study is designed to prospectively collect blood samples and clinical data from patients that have been newly diagnosed with colorectal cancer and scheduled for resection surgery but are pre cancer treatment, subjects who are NOT scheduled for surgery but have histological confirmation of CRC from the diagnostic colonoscopy and clinical staging (cTMN) is available and are pre- treatment, and patients who are at average risk of colorectal cancer and who are scheduled for routine colonoscopy examinations.
