趋化因子受体CCR7在结肠癌及转移淋巴结中的表达及其意义

Expression and clinical significance of chemokine receptor CCR7 in colon carcinoma and its corresponding lymphnode metastasis

目的探讨结肠癌原发灶及淋巴结转移灶中趋化因子受体CCR7的表达特点及其于临床病理特征的关系。方法对50例行结肠癌根植术的结肠癌组织标本及37例淋巴结转移灶采用免疫组化法检测CCR7表达。结果CCR7在62%(31/50)结肠癌组织中呈阳性表达,37例结肠癌原发灶和淋巴结转移灶中CCR7高表达的阳性率分别为81.1%(30/37)、75.7%(28/37),两部位CCR7表达具有较高的同源性。CCR7表达与淋巴结转移(P<0.01),侵润深度(P<0.01),肿瘤分期(P<0.01)密切相关,但与手术年龄、性别、肿瘤分期、肿瘤大小及分化程度无关。CCR7表达对结肠癌淋巴结转移判断的敏感性、特异性、阳性预测值及阴性预测值分别为81.1%(30/37),92.3%(12/13),96.8%(30/31),63.2%(12/19)。结论CCR7表达与结肠癌淋巴结转移密切相关、CCR7在结肠癌原发灶及转移淋巴结中的表达具有较高的同源性,CCR7表达对结肠癌手术方式的选择及非手术治疗选择靶点具有指导价值。

Objective: To investigate the expression of chemokine receptor CCR7 in colon carcinoma and its corresponding lymph node metastasis and the relations with clincopathologic characterics.Methods: The expression of CCR7 in colon carcinoma tissues from 50 patients who underwent curative surgery and 37 cases of lymph node expression and clinical significance of chemokine receptor CCR7 in colon carcinoma and its corresponding lymph node metastasis were examined by immunohistochemistry.Results: CCR7 expression was ...
