摘要 采用S-P免疫组化法检测108例胆囊腺癌、46例癌旁组织、35例慢性胆囊炎切除标本的EMMPRIN,MMP1和TIMP1表达。结果示,胆囊腺癌EMMPRIN和MMP1表达阳性率及其评分明显高于癌旁组织、慢性胆囊炎和胆囊结石组织(P<0.01),而TIMP1则相反(P<0.01);胆囊腺瘤癌变或高分化腺癌、肿块最大径<2 cm、无淋巴结转移及未侵犯周围组织的病例其EMMPRIN和MMP1阳性表达率及评分明显低于低分化腺癌、肿块最大径≥2 cm、淋巴结转移及侵犯周围组织的者(P<0.05或P<0.01),而TIMP1则相反(P<0.05或P<0.01);胆囊腺癌EMMPRIN与MMP1表达呈正相关(r=0.79,P<0.01),TIMP1与EMMPRIN(r=-0.64,P<0.01)和MMP1(r=-0.73,P<0.01)均呈负相关。提示:EMMPRIN,MMP1和TIMP1表达可反映胆囊癌发生、进展、生物学行为、侵袭或转移潜能,均为反映胆囊癌预后的重要生物学标记物;EMMPRIN诱导胆囊癌细胞产生MMP1,但抑制TIMP1的产生,TIMP1可能抑制EMMPRIN和MMP1的活性。
