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.
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.

Any surgery for primary tumor of colorectal cancer, including palliative resection, simple bowel stoma and exploratory surgery.
Zhongshan Hospital, Fudan University
Shanghai, Shanghai Municipality, China
RECRUITINGDisease-free survival time
For patients received radical resection of colorectal cancer, disease-free survival time is defined as time from the surgery to any recurrence of disease or death, recorded in months.
Time frame: 2 yeas after surgery
Overall survival time
Overall survival time is defined as time from the surgery to death, recorded in months.
Time frame: 2 yeas after surgery
Pathological TNM stage
The pathological TNM stage included the pathological T stage, pathological N stage and M stage. The pathological T and N stage is decided according to the removed specimen of the primary tumor by the pathologist after surgery. The M stage is decided according to the imaging tests as CT, MRI and PET-CT.
Time frame: 1 month after surgery
