大肠癌切除标本淋巴结检查最小数目的研究

Examination of the least number of lymph nodes in resected colorectal carcinoma specimens

目的 探讨大肠癌切除标本淋巴结应检出的最小数目。方法 以 10 76例大肠癌根治标本资料 ,分析淋巴结检出数目对转移率的影响 ,计算转移病例的累积百分率 ,推算应检查淋巴结最小数目。结果 当淋巴结检出数目逐渐增加时 ,转移率逐渐增加 ,达 16个以上后转移率无明显增加。结论 大肠癌标本淋巴结应检出的最小数目是 16个。

Objective To study the minimum number of lymph nodes required to be determined in the case of colorectal carcinoma being resected. Methods Data of 1?076 radically resected specimens were collected to analyse the correlation between the number of examined lymph nodes and the metastatic rate and cumulative percent of lymph node metastasis. Results The metastatic rate increased with the number of examined lymph nodes, but the lymph node metastasis rate did not increase again when the examined lymph nodes ≥16. Conclusions At least 16 lymph nodes must be examined to determine whether the patients with coloracted carcinoma have lymph node lymph metastasis or not.
