2、標(biāo)問及與GCA臨床病理特征的關(guān)系。結(jié)果腺癌組及癌旁組RKIP陽性表達(dá)率分別為38.75%、75.00%,兩組比較,P<0.01;NF—KBp65陽性表達(dá)率分別為75.625%、20.000%,兩組比較,P<0.01。RKIP陽性表達(dá)與GCA淋巴結(jié)轉(zhuǎn)移有關(guān)(P<0.05);NF—KBp65陽性表達(dá)與GCA臨床分期、腫瘤分化程度、淋巴結(jié)轉(zhuǎn)移有關(guān)(P均<0.05)。GCA組織中RKIP與NF—KBp65表達(dá)呈負(fù)相關(guān)(r=一0.431,P<0.01)。結(jié)論GCA組織中RKIP表達(dá)下調(diào)、NF—KBp65表達(dá)上升,RKIP表
