摘要: 目的:通过研究环氧合酶-2(COX-2)蛋白在胃癌组织中的表达,探讨其在胃癌发生、发展中的作用及与病理参数的关系。方法:应用免疫组织化学SP法检测12例正常胃组织及40例胃癌组织中COX-2的表达。 结果:COX-2在胃癌组织中的表达(87.5%)明显高于正常胃组织(25.0%)(P<0.05);Ⅲ+Ⅳ期胃癌中COX-2的表达(96.55 %)高于Ⅰ+Ⅱ期胃癌组织63.64%)(P<0.05);淋巴结转移组COX-2的表达(96.43%)高于无淋巴结转移组(66.67%) (P<0.05)。结论:COX-2蛋白的阳性表达与胃癌TNM分期及淋巴结转移有关,COX-2的高表达可能参与 了胃癌形成的过程,且与胃癌的侵袭、转移及预后有一定关系。

Abstract: Objective To investigate the expression of of cyclooxygenase-2 (COX-2) in human gastric carcinoma and to identify the significance of COX-2 expression. Methods COX-2 protein expressions were deteced in 12 nomal gastric mucosa and 40 gastric carcinoma tissues by immunohistochemistry.Results The expression of COX-2 in gastric carcinoma tissues (87.5%) was significantly higher than that in normal gastric mucosa (25.0%) (P<0.05). The expression of COX-2 in Ⅲ+Ⅳ stage of gastric carcinoma (96.55%) was higher than that in Ⅰ+Ⅱ stage (63.64%) (P<0.05); the COX-2 expression in lymph node metastasis group (96.43%) was higher than that in non-lymph node metastasis group (66.67%) (P<0.05). Conclusion The expression of COX-2 is related to TNM stages and lymph node metastasis. The expression of COX-2 maybe take part in the progress of gastric carcinoma and related to invasion,metastasis and prognosis.
