大肠癌临床特征与淋巴结转移规律分析

Clinical character and metastasis rule of the lymph node in the colon cancer.

目的探讨大肠癌临床特征与淋巴结转移规律,以便术中判断淋巴结是否转移。方法我院1990年1月至1999年12月,经手术病理确诊、资料完整病例214例进行临床特征与淋巴结关系分析,分析淋巴结转移情况。结果性别、年龄和肿瘤大小与淋巴结转移无明显相关(P>0.05),而肿瘤部位、组织学类型、分期、肿瘤浸润的深度与淋巴结有关系(P<0.05)。结论大肠癌手术时应注意淋巴结清扫范围,要根据淋巴结转移规律进行清扫,手术方式宜行D3式廓清术。

Objective To explore the clinical character and metastasis rules of the lymph node in the colon cancer,and improve the accuracy of judgment of lymph node metastasis during operation. Methods All 214 cases of colon cancer with complete materials were selected from 1990 to 1999 to analyse the relation between the clinical character and metastasis rules of the lymph node. Results The lymph node metastasis of colorectal cancer was related with the position of tumor ,the depth of tumor invasion and the differentiation of tumor cells（ P 〈0.05） ,but not with patients＇s sex ,age and the size of the tumor（ P 〉 0.05）. Conclusion Positive lymph node was presented to the cases without palpable lymph node. According to the metastasis rules of the lymph node to choose the cleaning range is necessary. D3 radical resection is suggested for colon cancer.
