The project mainly selects the tumor group represented by colon cancer and the corresponding healthy people as the control group, with about 100 cases in each of the two groups. Mainly collect blood and tumor tissue samples of patients, detect the expression of QSOX1 in the above samples, and explore the role in the diagnosis and prognosis evaluation of colon cancer.
The goal of this observational study is to determine whether the secreted protein QSOX1 can be used as a molecular marker for early rapid diagnosis and accurate treatment of colon cancer.
