摘  要:目的观察肝癌中Fas相关磷酸酯酶(FAP-1)的表达,探讨FAP-1表达与增殖和凋亡的关系,并分析其意义。方法采用免疫组织化学SP法检测60例肝癌及15例癌旁肝硬化组织标本中FAP-1蛋白的表达水平,设置10例正常肝组织为对照组。结果FAP-1蛋白的阳性表达主要定位在细胞质内,少数也可见胞膜着色。FAP-1蛋白在正常肝组织中未见表达,癌旁肝硬化组织中的表达率为6.7%,而在恶性肿瘤中的阳性表达率分别为78.3%,与前两者比较差异有统计学意义(P〈0.01)。FAP-1的表达率随肿瘤的转移临床分期晚和肿瘤分化程度低而增加,并与分化程度和转移性显著相关(P〈0.05),而与年龄和肿瘤大小无明显相关(P〉0.05)。结论FAP-1在肝癌组织中有广泛表达,且在临床有转移分期晚和病理分级低的组织中表达增高。Objective To investigate the roles of Fas-associated phosphatase-1 ( FAP-1 ) in the pathogenesis of hepatocellular carcinoma (HCC). Methods Immunohistochemical SP method was employed to detect the expression of FAP-1 in para-cancerous tissue ( 15 cases ), HCC ( 60 cases ) and the normal controls ( 10 cases). In addition, clinicopathological data of them were analyzed. Results There was no FAP-1 expression in normal controls and low positive expression rate in para-cancerous tissue (6.7%) ,but high positive expression rate (78.3%) was found in HCC (P 〈 0.01 ). Moreover, the expression of FAP-1 was markedly associated with metastasis and tumor pathological grade ( P 〈 0.05 ), but not with age and tumor size. Conclusion FAP-1 is widely overexpressed in HCC, and its expression is associated with metastasis and pathological grade.
