目的 探討胃癌淋巴管生成、淋巴管浸潤及淋巴結(jié)微轉(zhuǎn)移的臨床意義。方法 免疫組化法檢測68例胃癌原發(fā)灶中D2-40的表達(dá)及其中 51例胃癌的791枚淋巴結(jié)中CK20和CKpan的表達(dá)，結(jié)合患者的臨床病理特征進(jìn)行綜合分析。結(jié)果 胃癌HE染色淋巴管浸潤（LVI-HE）和D2-40染色淋巴管浸潤（LVI-IM）的陽性率分別為66.2%（45/68）和76.5%（52/68），差異無統(tǒng)計(jì)學(xué)意義(P=0.118)。LVI-IM陽性率與腫瘤浸潤深度（P=0.044）、TNM分期（P=0.003）及存在淋巴結(jié)轉(zhuǎn)移(P=0.000)有關(guān)。68例胃癌平均淋巴管密度（LVD）為（18.19±7.44）個(gè)/HP。 LVD升高與LVI-HE陽性（P=0.040）、LVI-IM陽性（P=0.001）、靜脈浸潤（P=0.037）、TNM分期較晚（P=0.020）及存在淋巴結(jié)轉(zhuǎn)移（P=0.001）有關(guān)系。LVD值≥15個(gè)/HP者近期生存率較LVD值≤14個(gè)/HP者明顯降低（P=0.032）。51例胃癌HE染色和CK（CK20或CKpan）染色檢出淋巴結(jié)轉(zhuǎn)移率分別為74.5%（38/51）和88.2%（45/51），791枚淋巴結(jié)的轉(zhuǎn)移淋巴結(jié)檢出率由HE染色的32.0%（253/791）提高到CK染色的41.5%（328/791），P＜0.001。CKpan的微轉(zhuǎn)移檢出率明顯高于CK20（P=0.003）。微轉(zhuǎn)移淋巴結(jié)數(shù)量與腫瘤大?。≒=0.001）、LVI-HE（P=0.040）、腫瘤浸潤深度（P=0.018）及TNM分期（P=0.012）有關(guān)。微轉(zhuǎn)移淋巴結(jié)的檢出使淋巴結(jié)轉(zhuǎn)移站別及TNM分期遷移： 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。結(jié)論 D2-40及CK檢測在診斷淋巴管浸潤和淋巴結(jié)微轉(zhuǎn)移上優(yōu)于HE檢查。CK20和CKpan的聯(lián)合檢查有利于發(fā)現(xiàn)微轉(zhuǎn)移淋巴結(jié)。腫瘤TNM分期越晚，越易發(fā)生淋巴結(jié)微轉(zhuǎn)移。LVI-IM、LVD及淋巴結(jié)微轉(zhuǎn)移三者都與胃癌淋巴結(jié)轉(zhuǎn)移有關(guān)。LVD值較高者近期生存率較低。
