    摘要:

    目的 探讨胶质瘤患者转移相关蛋白(Metastasis-associated protein, MTA)的表达情况和对患者生存时间的影响。方法 收集67例胶质瘤患者的肿瘤组织和18例取自脑外伤患者的正常脑组织,应用免疫组织化学方法检测所有组织MTA-1、MTA-2和MTA-3的表达情况,比较胶质瘤组织和正常脑组织中三种MTA的表达情况,并结合相关临床资料分析MTA表达情况的临床病理特征。采用Kaplan-Meier生存分析法对MTA及相关参数进行单因素分析,并对单因素分析p<0.05的参数采用Cox比例风险模型进行多因素回归分析。结果 胶质瘤组织的MTA-1和MTA-2阳性表达率明显高于正常脑组织(p=0.012;p=0.001),而MTA-3阳性表达率明显低于正常脑组织(p=0.001)。MTA-1阳性组和MTA-2阳性组患者WHO分型高等级肿瘤均多于阴性组,KPS评分均显著低于阴性组。而MTA-3阳性组患者高等级肿瘤少于阴性组,KPS评分高于阴性组。生存分析结果显示MTA-1、MTA-2、MTA-3、WHO分型、KPS得分及发病年龄均是胶质瘤患者生存时间的影响因素,Cox回归多因素模型分析结果提示WHO分型和肿瘤MTA-3的表达情况是患者生存时间的独立影响因素。结论 三种MTA均对胶质瘤患者的生存时间有重要影响作用,MTA-1和MTA-2的表达与患者生存时间负相关而MTA-3表达与胶质脑瘤生存时间正相关。

    Abstract:

    Objective To investigate the expression of metastasis-associated proteins (MTAs) in glioma patients and its influence on survival time.Methods Tumor tissues from 67 glioma patients and normal brain tissues from 18 patients with brain injury were collected. The expression of MTA-1, MTA-2, and MTA-3 in all the tissue samples was measured by immunohistochemistry and compared between glioma tissues and normal brain tissues; the clinicopathological features of MTA expression were analyzed with reference to related clinical data. The Kaplan-Meier survival analysis was applied for univariate analysis of MTA and related parameters, and the Cox proportional hazards model was applied for multivariate regression analysis of the parameters with P<0.05 determined by the univariate analysis.Results Compared with the normal brain tissues, the glioma tissues had significantly higher positive rates of MTA-1 and MTA-2 and a significantly lower positive rate of MTA-3 (P=0.012, 0.001, and 0.001, respectively). Compared with the corresponding negative groups, the MTA-1 positive group and the MTA-2 positive group had significantly higher numbers of the patients with high-grade tumors according to the WHO classification, as well as significantly lower Karnofsky Performance Scale (KPS) scores, while the MTA-3 group had a lower number of the patients with high-grade tumors and a higher KPS score. The results of univariate analysis showed that MTA-1, MTA-2, MTA-3, WHO classification, KPS score, and age of onset were the influencing factors for survival time in glioma patients, and the results of Cox multivariate regression analysis showed that WHO classification and MTA-3 expression were the independent influencing factors for survival time.Objective All three MTAs greatly influence the survival time in glioma patients, but with different mechanisms of action. Expressions of MTA-1 and MTA-2 may be negatively related with the survival time of patients, whereas MTA-1 may be positively related.
