Core Tip

Core Tip: Neutrophil extracellular traps (NETs) have been reported to participate in progression and metastasis in gastrointestinal (GI) cancer. Recent reports demonstrate that NET formation is enhanced in GI cancer patients as well as some mouse models and that elevated levels of NETs indicate an adverse outcome in patients. Furthermore, NETs can trap disseminated cancer cells and assist the formation of metastatic lesions although the underlying mechanisms remain vague. More studies are needed before NETs can be used as reliable biomarkers and therapeutic targets in GI cancer.
