1、B7H4、CA125及P53在上皮性卵巢癌中的表达及意义作者:孔凡荣,王黎明,戴淑真,孙显璐,吕艳华作者单位:青岛大学医学院附属医院1.妇科;2.病理科,山东青岛【摘要】目的探讨B7H4、CA125及P53在原发上皮性卵巢癌(EOC)中的表达及其之间的相互关系,以及与预后的关系。方法用免疫组织化学PV6000二步法测定B7H4、CA125及P53在70例上皮性卵巢癌、20例正常卵巢组织和20例良性卵巢肿瘤中的表达。结果B7H4在原发上皮性卵巢癌组织中阳性表达率88.6%(62/70)高于卵巢良性上皮肿瘤(45%)及正常卵巢组织
2、(0%)(P<0.05)。上皮性卵巢癌组织中CA125阳性表达率为77.1%(54/70),与B7H4表达呈正相关(r=0.720)。上皮性卵巢癌组织P53阳性表达率为68.6%(48/70)低于B7H4(P<0.05)。多因素Cox回归分析显示,上皮性卵巢癌的预后与FIGO分期、术后残癌灶大小、B7H4的表达、细胞分化程度、CA125的表达、淋巴结转移的有无及P53的表达相关;单因素分析显示,B7H4表达越强,平均生存时间越短,5年累积生存率越低。结论上皮性卵巢癌中B7H4表达上调,且B7H4表达与CA125的表达呈正相关
3、,高于P53的表达。B7H4为卵巢癌总生存期的独立危险因素,且有可能作为上皮性卵巢癌新的诊断和预后指标。【关键词】卵巢肿瘤;B7H4;蛋白质p53;预后ovariancancerandtheirclinicalvalueKONGFanrong1, WANGLiming1, DAIShuzhen1, SUNXianlu2, LYanhua1(1.DepartmentofGynecologyandobstetrics;2.DepartmentofPathology,AffiliatedHospitalofMedicalColl
