摘要 笔者采用免疫组织化学S-P法测定32例甲状腺癌组织、23例癌旁组织及30例良性甲状腺病变组织标本中MMP-9,IMP-1和IV型胶原的表达。结果示,MMP-9及TIMP-1在甲状腺癌组织中呈高表达(75.0%和56.3%),在癌旁组织及良性病变组织中呈低表达(30.3%,21.7%和26.7%,23.3%)(P<0.05)。MMP-9及TIMP-1蛋白的表达与浸润程度、淋巴结转移、TNM分期有关(P<0.05),MMP-9蛋白表达与TIMP-1呈负相关(r=-0.509,P=0.003)。IV型胶原在甲状腺癌组织中呈低表达(34.4%),在癌旁组织及良性病变组织中呈高表达(73.9%和83.3%,P<0.05)。IV型胶原的表达与MMP-9蛋白的表达呈负相关(r=-0.494,P=0.004)。提示检测甲状腺肿瘤患者病变组织中MMP-9,TIMP-1和IV型胶原的表达有助于鉴别诊断甲状腺良恶性肿瘤,并可作为评估甲状腺癌预后的参考指标。
