摘　　要：目的探讨CK7、CK20、Villin、CDX-2、MUC-2、PAX8在卵巢原发性黏液性肿瘤(OPMN)和卵巢继发性腹膜假黏液瘤(OS-PMP)中的表达及鉴别意义。方法收集经组织学和临床资料证实的OPMN 22例,OS-PMP 31例,采用免疫组化EnVision两步法检测CK7、CK20、Villin、CDX-2、MUC-2、PAX8的表达。结果CK7、PAX8在OPMN中的阳性率显著高于OS-PMP(分别为100%vs.9.7%,63.6%vs.0)(P<0.01)。CK20、CDX2、MUC2在OSPMP中的阳性率显著高于OPMN(分别为100%vs.9.1%,100%vs.18.2%,100%vs.9.1%)(P<0.01)。Villin在OS-PMP中的阳性率显著高于OPMN(100%vs.68.2%)(P<0.05)。CK7、CK20、CDX-2、MUC-2在OS-PMP诊断中均具有较高的敏感性(分别为90.3%、100%、100%、100%)及特异性(分别为100%、90.9%、81.8%、90.9%)。而Villin、PAX8敏感度性(100%),但特异性较低(分别为31.8%、54.5%)。结论CK7、CK20、Villin、CDX-2、MUC-2、PAX8推荐用于任何临床或病理特征提示继发性起源的卵巢黏液性肿瘤。CK7、CK20、CDX-2、MUC-2是高度敏感性及特异性的免疫组化鉴别诊断标志物。Objective To investigate the expression and differential significance of CK7,CK20,Villin,CDX-2,MUC-2 and PAX8 in ovarian primary mucinous neoplasms(OPMN)and ovarian secondary pseudomyxoma peritonei(OS-PMP).Methods A total of 22 OPMN and 31 OS-PMP confirmed by histological and clinical data were collected.The expression of CK7,CK20,Villin,CDX-2,MUC-2 and PAX8 was detected by immunohistochemical EnVision method.Results The expression of CK7 and PAX8 in OPMN was significantly higher than those in OS-PMP(100%vs.9.7%,63.6%vs.0,respectively)(P<0.01).The expression of CK20,CDX2 and MUC2 in OS-PMP was significantly higher than those in OPMN(100%vs.9.1%,100%vs.18.2%,100%vs.9.1%,respectively)(P<0.01).The expression of Villin in OSPMP was significantly higher than that of OPMN(100%vs.68.2%)(P<0.05).CK7,CK20,CDX-2 and MUC-2 showed high sensitivity(90.3%,100%,100%,100%,respectively)and specificity(100%,90.9%,81.8%,90.9%,respectively)in OS-PMP.Villin and PAX8 showed high sensitivity(100%)but low specificity(31.8%and 54.5%,respectively).Conclusion CK7,CK20,Villin,CDX-2,MUC-2 and PAX8 are recommended in the work-up of ovarian mucinous tumors with any clinical or pathological features suggestive of secondary origin.CK7,CK20,CDX-2 and MUC-2 are highly sensitive and specific immunohistochemical markers for the differential diagnosis.
