摘要
[目的]探讨大肠癌的组织学分型、浸润与淋巴结转移的关系。[方法]回顾性研究725例大肠癌根治标本中具有淋巴结转移的275例病理资料。[结果]未分化癌最常发生淋巴结转移(3/4) ,其它依次为鳞癌(2/3)、印戒细胞癌(7/12)、低分化腺癌(56/92)、粘液腺癌(56/100)、中分化腺癌(135/381)及高分化腺癌(16/131)。其中肠管全层浸润210例 ,侵犯深肌层57例 ,浅肌层8例。[结论]大肠癌的淋巴结转移与组织学分型、肿瘤细胞的分化程度及浸润的范围具有密切关系。
To investigate the correlation between histological classification and lymph node metastasis in colorectal carcinoma.Retrospective analysis was made in 725 cases of colorectal carcinoma.275 cases of them were found in lymph node metastasis.Lymph-node metastasis was most frequent in undifferentiated carcinoma(3/4), with descending order in squamous cell carcinoma (2/3), signet ring cell carcinoma (7/12), low differentiated adenocarcinoma (56/92),mucous adenocarcinoma(56/100),moderate differentiated adenocarcinoma(135/381) and well differentiated adenocarcinoma(16/131).Among these lymph node metastasis,210 cases has infiltrated to whole thickness of the wall,57 cases has infiltrated to deep muscular layes and only 8 cases has infiltrated to shallow muscular layes.[Conclusion]Lymph node metastasis is closely related to histologic type, grade and depth of invasion.
