In this study, the investigators will establish a database to collect clinical pathological information, based on the medical data system of participating medical centers. The investigators will also collect corresponding tumor specimens and perform multiple omics tests such as genome, transcriptome, and proteome. The investigators will aggregate these data into a special database, and use appropriate methods to conduct big data analysis, to predict prognosis, guide diagnosis and treatment, and assist in formulating health policies.
This study aims to establish a colorectal cancer cohort, collect clinicopathological information, collect biological samples for multi-omics testing, and perform relevant analysis, to predict the prognosis of colorectal cancer, guide the diagnosis and treatment of colorectal cancer and the formulation of health policies.
