环氧化酶-2(cyclooxygenase-2,COX-2)是前列腺素合成的限速酶,近来大量的研究提示其不仅在肿瘤发生过程中起作用,而且在多种肿瘤的转移过程中起重要作用〔1〕。目前有关COX-2在甲状腺癌原发灶和转移灶中的表达水平及差异的研究均未见报道,我们通过免疫组织化学SP法检测甲状腺癌
Cyclooxygenase-2 (cyclooxygenase-2, COX-2) is a rate-limiting enzyme in the synthesis of prostaglandins. Recently, a large number of studies have shown that it plays a role not only in tumorigenesis, but also in the metastasis of various tumors Role [1]. At present, there is no report about the expression level and difference of COX-2 in primary and metastatic thyroid cancer. We detected thyroid cancer by immunohistochemical SP method
