本文从形态学基础的角度,采用根治切除的进展期直肠癌标本,对直肠癌淋巴转移规律进行了研究。本组170例共77例转移,转移率为45.3％;共检取淋巴结5912个,平均34.8个/例,其中转移淋巴结527个,转移度为9.0％。肿瘤存在的部位就侧方转移而言,不同部位的肿瘤淋巴转移率差异极其显著。 This article from the perspective of morphology, using radical resection of advanced rectal cancer specimens, to study the law of lymph node metastasis. In this group of 170 patients with a total of 77 cases of metastasis, the metastatic rate was 45.3%; a total of 5912 lymph nodes were detected, an average of 34.8 cases / case, of which 527 metastatic lymph nodes, the degree of metastasis was 9.0%. In terms of side-to-side metastasis in the presence of tumors, the difference in tumor lymphatic metastases at different sites is extremely significant.
