摘    要:
目的探讨胃癌淋巴管生成、淋巴管浸润及淋巴结微转移的临床意义。方法免疫组化法检测68例胃癌原发灶中D2-40的表达及其中51例胃癌的791枚淋巴结中CK20和CKpan的表达,结合患者的l临床病理特征进行综合分析。结果胃癌HE染色淋巴管浸润(LVI-HE)和D240染色淋巴管浸润(LVI-IM)的阳性率分别为66.2%(45/68)和76.5%(52/68),差异无统计学意义(P=0.118)。LVI-IM阳性率与肿瘤浸润深度(P=0.044)、TNM分期(P=0.003)及存在淋巴结转移(P=0.000)有关。68例胃癌平均淋巴管密度(LVD)为(18.19±7.44)个/HP.LVD升高与LVI-HE阳性(P=0.040)、LVI—IM阳性(P=0.001)、静脉浸润(P=0.037)、TNM分期较晚(P:0.020)及存在淋巴结转移(P=0.001)有关系。LVD值≥15个/HP者近期生存率较LVD值≤14个/HP者明显降低(P=0.032)。51例胃癌HE染色和CK(CK20或CKpan)染色检出淋巴结转移率分别为74.5%(38/51)和88.2%(45/51),791枚淋巴结的转移淋巴结检出率由HE染色的32.0%(253/791)提高到CK染色的41.5%(328/791),P〈0.001。CKpan的微转移检出率明显高于CK20(P=0.003)。微转移淋巴结数量与肿瘤大小(P=0.001)、LVIHE(P=0.040)、肿瘤浸润深度(P=0.018)及TNM分期(P=0.012)有关。微转移淋巴结的检出使淋巴结转移站别及TNM分期迁移:7例N0→N1,6例N1→N2,1例N2→N3;4例Ⅰb→Ⅱ,4例Ⅱ→Ⅲa,3例Ⅲa→Ⅲb,1例Ⅲb→Ⅳ。结论D2-40及CK检测在诊断淋巴管浸润和淋巴结微转移上优于HE检查。CK20和CKpan的联合检查有利于发现微转移淋巴结。肿瘤TNM分期越晚,越易发生淋巴结微转移。LVI-IM、LVD及淋巴结微转移三者都与胃癌淋巴结转移有关。LVD值较高者近期生存率较低。
