Vascular invasion is an unfavorable prognostic factor for the recurrence and systemic metastasis of colon cancer. An interesting study in this issue evaluate the difference in the oncological impact of vascular invasion according to tumor side in colon cancer. The authors suggest that the oncological impact of vascular invasion could be worse in nonmetastatic right colon cancer than in nonmetastatic left colon cancer. Herein, hematoxylin-eosin staining was used to detect vascular invasion. In a recent study, elastin staining could detect more venous invasion. It is expected that the molecular pathologic characteristics of colon cancer can be identified precisely and the oncological outcomes of colon cancer can be improved in the future.
血管侵犯是结肠癌复发和全身转移的不良预后因素。本期一项有趣的研究评估了结肠癌中血管侵犯对肿瘤学影响在肿瘤部位方面的差异。作者认为,在非转移性右结肠癌中,血管侵犯对肿瘤学的影响可能比非转移性左结肠癌更严重。在此,苏木精-伊红染色用于检测血管侵犯。在最近的一项研究中,弹性蛋白染色能检测到更多的静脉侵犯。预计未来能够精确识别结肠癌的分子病理特征并改善结肠癌的肿瘤学结局。
