【摘要】 1982~1993年间,我院共行大肠癌手术1234例,为探讨大肠癌合理术式,以其中340 例PM大肠癌淋巴结转移情况与SM癌,SS癌进行比较,进行临床病理学研究,PM大肠癌淋巴结转移率24%,肿瘤型淋巴结转移率为16%,溃疡型PM癌淋巴结转移率28%。直肠下段肿瘤型癌不需进行侧方清除术,溃疡型可行肿瘤侧单侧侧方清除术,肌内浸泣深度与淋巴结转移关系密切, 浅肌层淋巴结转移率为13%,深肌层淋巴结转移率为26%。浅肌层PM癌无需行R3淋巴结扩散清术,分化型PM癌淋巴结转移率为24%,粘液腺癌淋巴结转移为36%。我们认为在决定PM大肠癌术式问题上应重点考虑以下三个因素:1)肿瘤大体形态;2肌内浸泣深度;3)肿瘤组织学类型。
【Abstract】 From 1982 to 1993, 1234 cases with colorectal cancer received surgical treatment in our hospital. In order to detect the proper operation type for colorectal cancer, a clinicopathological study was carried out with the comparison of lymph node metastases between MP colorectal cancer (340 cases)and SM, SS cancer. The lymph node metastases rate was 24% in MP cancer, and 16% in tumorous type 28% in ulcerative type. Lateral clearance is not necessary for tumorous cancer at low segment of rectum, but one side clearance can be done for ulcerative type cancer. And we found that the lymph node metastases was closely related to the depth o invasion in muscular layer. The lymph node metastases rate was 13% in superficial muscular cancer and 26% in deep muscular cancer. Lymph node clearance at R3 level is not necessary for superficial muscular cancer. Lymph node metastases rate was accounted in 24% in differentiated Mp cancer and 36% in mucous adenocarcinoma. We think that determining the type of operation for MP carcinoma of large bowel the three factors should be emphasized in :1) gross morphology of tumor 2)depth of invasion m muscular layers 3)histologic classification of tumor
