      Extramural venous invasion (EMVI) in colorectal cancer is associated with increased cancer recurrence and cancer-related death.
      ] in which they conducted a single-institutional retrospective study that included 654 patients with non-metastatic colorectal cancer (CRC), to illustrate the impact of extramural venous invasion (EMVI) on the long-term survival outcomes of these patients. The authors concluded that the presence of EMVI was significantly associated with poor prognosis of CRC patients independent of histopathological characteristics. Considering the importance of EMVI for predicting CRC recurrence and determining the necessity of postoperative adjuvant chemotherapy (AC), the implications and novelty of this study should be highlighted. However, we would like to raise the following comments.
