Core Tip

Core tip: Although cancer-related stroke has long been known, its biomarkers and underling pathogenesis are still unclear. It was hypothesized that a specific cancer type may affect the development of ischemic stroke (IS) according to its primary site, pathological type, and growth stage. It is reported that colorectal cancer can increase the risk of IS. We conducted a retrospective study on colorectal cancer-related IS (CRCIS) patients. We suggest that hypercoagulability induced by elevated carcinoembryonic antigen and increased neutrophil count are the main pathogenic factors in CRCIS, and the CRCIS Index, which serves as a biomarker of CRCIS, needs further study.
