摘要: 对73例原发性大肠癌(淋巴结转移37例,非转移36例)进行P53、nm23、CD44及纤维粘连蛋白(FN)免疫组化检测,研究其表达与淋巴结转移的关系。结果显示,nm23阴性表达与CD44阳性表达在淋巴结转移组与非转移组之间有显着性差异(P<0.01).2项指标串联筛检,预测淋巴结转移的特异性为97.22%,敏感性为56.76%.nm23表达水平与大肠癌淋巴结转移呈负相关,CD44则呈正相关,2项指标联合应用可作为预测淋巴结转移的1项比较客观的指标。

Abstract: To assess the relationship of P53, nm23, CD44 and FN with lymph node metastasis of colorectal carcinoma, the expression of the four proteins was examined from 73 cases of colorectal carcinomas(37 cases with lymph node metastasis and 36 cases without metastasis) using immunohistochemical method. The low expression of nm23 and the positive expression of CD44 were significant difference between metastasis group and nonmetastasis(P<0.01). When using the combination of nm23 and CD44 to predict the lymph node metastasis, the specificity was 97.22%, and the sensitivity was 56.76%. An inverse correlation was observed between nm23 expression and lymph node metastasis. While CD44 expression showed a positive correlation. The combination of the two tests may be used as Author a objective parameter in predicting the lymph node metastasis of colorectal carcinoma.

Key words: colorectal carcinoma, lymph node metastasis, P53, nm23, CD44, FN
