Core Tip

Core tip: The 4-point computed tomography extramural vascular invasion (ctEMVI) detection and grading system has been described and validated as a method for predicting disease-free survival (DFS) in colon cancer patients. In this study, we assess the difference in DFS between ctEMVI-positive and -negative colon cancer patients. ctEMVI status as well as pathological T and N status were independent adverse prognostic indicators for colon cancer patients. ctEMVI, in conjunction with the extent of extramural spread and lymph node burden, may become a novel and clinically significant imaging evaluation parameter when deciding whether patients with colon cancer should receive neoadjuvant treatment.
