SOX11在胶质母细胞瘤中的表达及其临床病理学意义(1)
[摘要] 目的 探讨SOX11在胶质母细胞瘤中的表达及其临床病理学意义。 方法 收集2010年9月~2017年1月安徽省立医院病理科存档的胶质母细胞瘤石蜡包埋样本264例,每例样本选取肿瘤区域及瘤旁正常脑组织制作组织芯片,采用全自动免疫组化方法检测SOX11的表达,并分析SOX11表达与患者临床病理特征的关系。结果 胶质母细胞瘤中SOX11表达的总阳性率和强阳性率显著高于配对的瘤旁正常组织(P < 0.01);SOX11表达与肿瘤直径、Ki67增殖指数相关(P < 0.01),但其与患者年龄、性别、病灶单发/多发无关(P > 0.05)。 结论 SOX11在胶质母细胞瘤中特异性表达,可作为胶质母细胞瘤病理诊断的标志物,其表达水平可能与肿瘤进展有关。

[Abstract] Objective To investigate the expression and clinical pathological significance of SOX11 in glioblastoma. Methods A total of 264 cases of paraffin-embedded glioblastoma were collected from the Department of Pathology, Anhui Provincial Hospital from September 2010 to January 2017. Each sample was selected from the tumor area and the normal brain tissue of the tumor to make tissue chips. The expression of SOX11 was detected by immunohistochemistry and the relationship between SOX11 expression and clinicopathological features was analyzed. Results The total positive rate and strongly positive rate of SOX11 expression in glioblastoma was significantly higher than that in matched normal tissues of the tumor (P < 0.01). The expression of SOX11 was correlated with tumor diameter and Ki67 proliferation index (P < 0.01), but it was not related to the patient′s age, gender, single/multiple lesions (P > 0.05). Conclusion SOX11 is specifically expressed in glioblastoma and can be used as a marker for the pathological diagnosis of glioblastoma. The expression level of SOX11 may be related to tumor progression.

膠质母细胞瘤(glioblastoma,GBM)为颅内高度恶性原发性肿瘤,肿瘤生长迅速,易复发、转移和耐药,预后很差。Y染色体性别决定区相关的高迁移率族盒蛋白(SRY-related HMG-box,SOX)作为转录因子,通过HMG结构域介导DNA结合,调节特定生物过程。SOX11属于SOX家族C亚族,参与调控胚胎发育和决定细胞命运,对调节神经元细胞的存活和细胞突起的生长有重要作用[1]。近年来,随着对SOX11的深入研究,发现SOX11可能对肿瘤细胞的存活、生长和转化发挥作用,但SOX11异常表达的机制在很大程度上是未知的。本研究采用免疫组化法检测264对配对的GBM及瘤旁正常脑组织中SOX11蛋白的表达,探讨其在GBM中的临床病理学意义,旨在为临床诊疗提供新方向。
1 资料与方法
1.1 一般资料
收集2010年9月~2017年1月安徽省立医院病理科存档的GBM石蜡包埋标本264例(男162例,女102例,中位年龄59岁),均以10%中性甲醛固定。GBM标本的选择依据世界卫生组织(WHO)中枢神经系统胶质瘤分类标准(2016)。采用双盲法,2位病理医师分别对苏木精-伊红(HE)染色切片进行重新复审。每例样本选取无出血坏死、肿瘤细胞丰富的肿瘤区及瘤旁正常脑组织制作组织芯片。纳入的患者术前未进行放、化疗等抗肿瘤治疗。所有患者对本研究知情同意并签署知情同意书,且本研究中使用的组织标本经医院医学伦理委员会批准。
