Summary

This multi-center study aims to develop a precise predictive model for colorectal cancer (CRC) recurrence and metastasis based on multi-omics analysis of portal vein blood. Despite advances in surgical treatments, approximately 40% of CRC patients experience tumor recurrence or metastasis post-surgery, with 80-90% of metastases being unresectable. The study will include stage I-IV CRC patients and will be conducted in two phases: a nested case-control study and a bidirectional cohort study. Comprehensive multi-omics sequencing will be performed on samples from primary tumors, adjacent tissues, normal intestinal tissues, portal vein blood, and peripheral blood. The goal is to identify specific biomarkers in the portal vein and peripheral blood associated with CRC recurrence and metastasis, and to compare the predictive accuracy of models based on these biomarkers. The ultimate objective is to provide a more effective method for early prediction and intervention of CRC recurrence and metastasis, thereby improving patient outcomes.
