【摘要】目的探討檢測乳腺癌腋窩淋巴結(jié)轉(zhuǎn)移較敏感的方法。
方法應(yīng)用常規(guī)HE染色法、細(xì)胞角蛋白19（CK19）作為單抗的免疫組化（IHC）SP染色及CK19 mRNA的逆轉(zhuǎn)錄聚合酶鏈反應(yīng)（RT-PCR）3種方法檢測20例乳腺癌患者共239個(gè)腋窩淋巴結(jié)的轉(zhuǎn)移情況。
結(jié)果239個(gè)腋窩淋巴結(jié)中，HE染色發(fā)現(xiàn)3例患者7個(gè)（2.9%，7/239）有癌轉(zhuǎn)移，均位于level Ⅰ； IHC檢測到7例患者13個(gè)（5.4%，13/239）有癌轉(zhuǎn)移，其中11個(gè)位于level Ⅰ，2個(gè)位于level Ⅱ； RT-PCR檢測到14例患者52個(gè)（21.8%，52/239）有癌轉(zhuǎn)移，其中30個(gè)位于level Ⅰ，22個(gè)位于level Ⅱ。IHC和RT-PCR檢測證實(shí)，HE染色陽性的7個(gè)淋巴結(jié)均有癌轉(zhuǎn)移； IHC染色陽性的淋巴結(jié)均出現(xiàn)了PCR陽性擴(kuò)增產(chǎn)物。HE、IHC及RT-PCR 3種檢測方法對腋窩淋巴結(jié)微轉(zhuǎn)移的檢出率分別是0(0/232)、2.6%(6/232)及19.4%(45/232），P＜0.05。
結(jié)論 IHC及RT-PCR是較HE檢測淋巴結(jié)微轉(zhuǎn)移更敏感的方法，而RT-PCR較IHC更為敏感，能更準(zhǔn)確地反映乳腺癌患者腋窩淋巴結(jié)的狀況。
