【摘要】 目的探讨Maspin蛋白在口腔鳞状细胞癌(OSCC)发生发展过程中的作用,为临床应用提供理论依据。方法采用鼠抗人Maspin单克隆抗体及SP免疫组化法检测45例OSCC、33例癌旁组织及15例正常口腔组织中Maspin蛋白的表达水平,用半定量积分法判断结果。结果在正常口腔组织、癌旁组织和OSCC组织中Maspin蛋白表达阳性率分别为86.67%(13/15)、72.73%(24/33)和37.78%(17/45)。Maspin蛋白在OSCC组织、癌旁组织和正常口腔组织中表达逐渐增高,其中OSCC组织和正常口腔组织、OSCC组织和癌旁组织、癌旁组织和正常口腔组织之间表达差异有统计学意义(P<0.05)。Maspin蛋白的表达与OSCC淋巴结转移和组织学分级有关(P<0.05),与TNM分期无关(P>0.05)。结论Maspin蛋白在OSCC的发生发展过程中可能起着重要作用,检测OSCC组织中Maspin蛋白的表达水平可能有助于对淋巴结转移潜能的预测。更多还原

【Abstract】 Objective To investigate the role of Maspin protein in the development of oral squamous cell car- cinoma(OSCC), with the effort to realize practical diagnosis use of them. Methods The expression status of Maspin protein in 45 cases of OSCC, 33 cases of paratumor tissue and 15 cases of normal tissue was examined by immunohistochemical staining. Results The positive rates of Maspin protein were 86.67%(13/15), 72.73%(24/33) and 37.78%(17/45) in normal tissue, paratumor tissue and OSCC. The expression of Maspin protein increased respectively in OSCC, paratumor tissue and normal tissue. The expression were different between OSCC and normal tissue, OSCC and paratumor tissue, paratumor tissue and normal tissue(P<0.05). The expression of Maspin protein was correlated with lymph node metastasis, histological grade(P<0.05), but not with TNM staging(P>0.05). Conclusion Maspin protein may play an important role in the development of OSCC. The expression level of Maspin protein de- tected in early time might be a useful prognostic marker for the diagnosis of lymph node metastasis.更多还原
