摘要 目的观察子宫内膜癌组织中p63、细胞角蛋白5/6(CK5/6)的表达变化,并探讨其临床意义。方法采用免疫组化SP法检测25例(A组)子宫内膜增生、20例(B组)非典型子宫内膜增生及26例(C1组)子宫内膜样腺癌浸润肌层<1/2、14例(C2组)浸润肌层>1/2组织中的p63和CK5/6。结果 A组p63阳性23例,B组20例,P>0.05;A组平均阳性指数(ASI)为0.65±0.15,B组为0.38±0.23,P<0.05;C1组p63阳性2例,C2组0例,P>0.05;C1组ASI为0.21±0.11,C2组为0,P<0.05;A组CK5/6阳性22例,B组18例,P>0.05;A组ASI为0.66±0.15,B组为0.36±0.22,P<0.05;C1组CK5/6阳性3例,C2组0例,P>0.05;C1组ASI为0.22±0.10,C2组为0,P<0.05;C1组p63和CK5/6阳性表达率、ASI均高于B组,P均<0.05。子宫内膜增生和子宫内膜样腺癌组织中,p63和CK5/6表达的ASI呈正相关(r分别为0.235、0.257,P均<0.05)。A、B、C1、C2组10年生存率分别为100.0%、75.0%、50.0%、14.3%,P均<0.05。结论子宫内膜样腺癌组织中p63和CK5/6表达减少,二者在子宫内膜样腺癌的诊断及病情发展和预后判断中有一定指导作用。
