摘要:

目的:探讨TGF-B与口腔鳞癌发生和发展的关系。方法:采用SABC免疫组化法检测了40例口腔鳞癌术后标本和20例正常口腔粘膜中TGF-B的表达。结果:口腔鳞癌和正常口腔粘膜中均表达TGF-B1、TGF-B2、TGF-B3,但程度不同。TGF-B1、TGF-B2在口腔鳞癌中呈过表达。口腔鳞癌临床分期、有无颈淋巴结转移及病理分级与TGF-B1、 TGF-B2过表达有关,与TGF-B3的表达无关。结论:TGF-B1和TGF-B2可能参与了口腔鳞癌的发生发展及颈淋巴结转移过程,是口腔鳞癌发生发展及预后的一个指标。

Abstract:

Objective:The objective of this study was to determine the expression of transforming growth factor beta (TGF-B) subtypes and their relationship with the mechanisms of squamous cell carcinoma (OSCC) growth.Methods:Totally 40 cases of surgical specimens of OSCC resected between 1998 and 2000 and 20 cases of normal human oral mucosa were investigated. Strepto-adri- dinibiotin complex (SABC) immunohistochemical staining was used to analyze the expression of TGF-Bprotein subtypes and their relations with clinical prognosis of OSCC.Results:Semi-quantitative analysis revealed that the subtypes 1, 2 and 3 of TGF-Bpro- tein could be found in OSCC cells and normal oral epithelial cells, however the intensity of protein expressionwas different. Com- paring with those in normal oral mucosa epithelial cells, the subtypes 1 and 2 of TGF-Bwere over-expressed in OSCC cells. The over-expression of subtypes 1 and 2 of TGF-Bproteinwere associatedwith theirpathological grades, clinical stages and neck lymph node metastasis (P<0.05), whilstthe subtype 3 protein of TGF-Bwas not.Conclusion:Itwill be useful to detectthe expression of TGF-Bsubtypes in OSCC, as the subtypes 1 and 2 of TGF-Bmay play an important role in OSCC growth and metastasis.
