结肠癌通过三种途径转移播散 :淋巴循环 ,门静脉和腹膜表面。尽管淋巴和血路转移提示疾病晚期 ,腹膜播散可能只是脏层和壁层腹膜的表面污染所致 ,有治愈可能。不幸的是 ,外科手段可能对腹膜播散产生不利影响 ,使表浅的病变浸润生长 ,使愈后明显下降。本前瞻性研究比较同期处理 Colon cancer metastasizes through three pathways: lymphatic circulation, portal vein and peritoneal surface. Although lymphatic and hematogenous metastases suggest advanced disease, peritoneal dissemination may be due to surface contamination of the visceral and parietal peritoneum, and there may be a cure. Unfortunately, surgical procedures may have an adverse effect on peritoneal dissemination, allowing superficial lesions to infiltrate and grow, resulting in a significant decrease afterwards. This prospective study compares the same period
