Colorectal cancer (CRC), one of the most common malignant cancer around the world, CRC patients with distant metastasis. However, the pathogenesis of metastasis remains unclear. Integrative omics have begun to enable personalized medicine at an extraordinarily detailed molecular level. All patients with colorectal cancer and metastasis in our center who meet the inclusion criteria and exclusion criteria will be enrolled. The specimen collected by surgery and clinical data will be collected . We use Integrative omics such as RNA-sequencing,ATAC-seq(Assay for Transposase-Accessible Chromatin using sequencing), CUT\&Tag（ Cleavage Under Targets and Tagmentation）to analyze and predict candidate biomarkers of colorectal cancer and distant metastasis. This study will contribute to understanding the molecular mechanism of CRC metastasis in depth and contribute to the discovery of new appropriate molecular diagnostic and therapeutic targets, and more accurately prognose long term outcome in patients with CRC.
