摘要 目的:研究环氧合酶-2(cyclooxygenase-2,COX-2)、碱性成纤维细胞生长因子(basic fibroblast growth factors,bFGF)在口腔鳞状细胞癌(oral squamous cell carcinoma,OSCC)的发生、发展过程中的表达情况,进而探求COX-2、bFGF在OSCC发生发展过程中的作用及相互关系。方法:应用COX-2,bFGF多克隆抗体对25例口腔白斑(癌前病变)(oral leukoplakia,OLK)、23例口腔鳞状细胞癌进行检测,另取10例口腔正常颊、舌黏膜组织为对照组,做组织切片进行免疫组化研究。结果:COX-2在正常口腔黏膜不表达,bFGF在正常口腔黏膜仅为弱表达或不表达,COX-2、bFGF在口腔白斑中有一定的表达,染色强度与正常口腔黏膜相比具有显著性差异(P<0.01 ),COX-2、bFGF在口腔鳞癌中高表达,其染色强度强于口腔白斑(P<0.01),口腔鳞癌中COX-2的表达阳性率为82.61%,bFGF的表达阳性率为86.96%,二者共同表达阳性率为78.26%,r=0.8,P<0.05,二者表达呈正相关关系。结论:COX-2、bFGF在口腔鳞癌发生、发展中起着重要作用,二者表达显著相关,在口腔鳞癌的发生发展中有协同作用,COX-2可促进bFGF的形成。 Objectives:To study the role of COX-2 and bFGF in the development of oral squamous cell carcinoma(OSCC). Methods:The expressions of COX-2 and bFGF were exmined by immunohistochemical staining with anti-COX-2 and anti-bFGF monoelonal antibodies respectively in 23 cases of OSCC, 25 of oral leukoplakia (OLK) and 10 of normal oral mucosa. Results:COX-2 was detected in 20/23 cases of OSCC, 13/25 of OLK and 0/10 of normal oral mucosa( P 〈 0. 01 ). bFGF was detected in 19/23 cases of OSCC, 13/25 of OLK and 1/10 of normal oral mucosa( P 〈 0. 01 ). Co-expression rate of COX-2 and bFGF in OSCC was 78.26% ( 18/23, r = 0. 8). Conclusion: COX-2 and bFGF may play an important role in the development of oral squamous cell carcinoma.
