摘要:

目的探讨骨桥蛋白(OPN)及其受体CD44v6在口腔鳞状细胞癌(OSCC)中的蛋白定量表达、临床意义及二者之间的关系。方法应用EnVisionTM法检测正常口腔黏膜(n=12)和OSCC患者(n=59)肿瘤组织中OPN和CD44v6的表达,结合图像分析系统进行定量分析,统计不同临床、病理指标下OSCC肿瘤组织中OPN的表达情况以及两种蛋白表达的相互关系。结果OPN在OSCC肿瘤组织中的表达显著高于正常口腔黏膜(P<0.05)。OPN的表达与OSCC不同临床分期、颈淋巴结转移有相关性,在OSCC高分化和中低分化者间差异无统计学意义。CD44v6在OSCC与正常口腔黏膜中差异无统计学意义,且其表达与临床病理指标关系不密切。在OSCC中,OPN与CD44v6表达无显著相关性。结论OPN在OSCC存在过度表达,其表达水平与肿瘤临床分期以及有无淋巴结转移存在一定的相关性,CD44v6与肿瘤临床病理特征无关,而且与OPN表达无相关性。

Abstract:

Objective To study the clinical significance of osteopontin(OPN) and its receptor CD44v6 expression in oral squamous cell carcinoma(OSCC). Methods OPN and CD44v6 expression were examined in OSCC(n=59)and normal oral mucosa(n=12)by EnVisionTM method, the staining- grade were quantitatively studied by multiple functional image analyzer. Their expression grade of different clinical and pathological index were statistically studied. Results OPN expression grade was significantly higher in OSCC than that in normal oral mucosa(P<0.05). Significant deviation of OPN expression grade was found between different clinical stages, as well as between the groups with or without cervical lymph node metastasis. The group with cervical lymphnode metastasis had higher expression than that of the group without lymph node metastasis(P<0.05). However, there was no significant deviation between the expression grade in well- differentiated group and moderate or poorly differentiated group. The expression of CD44v6 showed no correlation with that of OPN, nor any difference between OSCC and normal oral mucosa. Conclusion OPN over expression was found in OSCC, and the expression level has correlation with the clinical staging and with cervical lymph node metastasis status. CD44v6 expression showed no difference between OSCC and normal oral mucosa nor any correlation with that of OPN.
