Abstract:

目的:探讨hr-HPV(16/18)DNA及4种免疫标记物(p16,Vimentin,ER,PR)表达组型的检测在宫颈腺癌(ECA)和子宫内膜腺癌(EMA)鉴别诊断中的价值。方法:分别采用原位杂交和免疫组化(EliVisionTMplus)法对ECA和EMA肿瘤组织中的hr-HPV(16/18)DNA和4种免疫标记物(p16,Vimentin,ER,PR)的表达进行检测。阳性表达细胞≤50%为低表达(L),>50%为高表达(H)。结果:1hr-HPV(16/18)DNA在ECA和EMA中的检出率分别为72.7%(24/33)和12.9%(4/31)。ECA中hr-HPV(16/18)DNA检出率显著高于EMA(P<0.01)。2在24例hr-HPV(16/18)DNA阳性的ECA病例中4种标记物组合有2种表达组型。其中23例(95.8%)呈p16(H)/Vim(L)/ER(L)/PR(L)表达类型,在9例hr-HPV(16/18)DNA阴性的ECA病例中,8例呈p16(L)/Vim(L)/ER(L)/PR(L)表达组型(88.9%)。3在27例hr-HPV(16/18)DNA阴性的EMA病例中,4种标记物组合有5种表达组型。其中21例(77.8%)为p16(L)/Vim(H)/ER(H)或/和PR(H)表达组型。在4例hr-HPV(16/18)DNA阳性EMA病例中,2例呈p16(H)/Vim(H)/ER(L)/PR(L)表达组型(50.0%),剩余2例(50.0%)分别为p16(H)/Vim(L)/ER(L)/PR(L)和p16(H)/Vim(H)/ER(H)/PR(H)表达组型。结论:hr-HPV(16/18)DNA检测和4种免疫标记物组合(p16,Vimentin,ER,PR)的不同表达组型在ECA和EMA的鉴别诊断中具有重要实用价值
