B7-H4、CA125及P53在上皮性卵巢癌中的表达及意义

目的探讨B7 H4、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PV 6000二步法测定B7 H4、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B7 H4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(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B7 H4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B7 H4（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、B7 H4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,B7 H4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B7 H4表达上调,且B7 H4表达与CA125的表达呈正相关,高于P53的表达。B7 H4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。

Expressions of B7-H4,CA_(125) and P53 in epithelial ovarian cancer and their clinical value

Objective To investigate expressions of B7-H4,CA125 and P53 in primary epithelial ovarian cancer(EOC) and to explore their relationship with prognosis.Methods Expressions of B7-H4,CA125 and P53 were determined by PV-6000 two-step immunohistochemistry in 70 cases of EOC,20 cases of normal ovarian tissues and 20 cases of benign ovarian tumors.Results The positive rate of B7H4 in epithelial ovarian cancer was 88.5%(62/70),and it was significantly higher than that in benign ovarian epithelial tumors(45%) and no...
