4-1BBL分子在脑胶质瘤组织中的表达及其临床意义

目的:探讨共刺激分子4-1BBL(CD137L)在胶质瘤组织中的表达及其临床意义。方法:免疫组化方法检测4-1BBL在82例脑胶质瘤组织中的表达,并分析其与病理分级、患者年龄、性别及生存时间的关系。结果:正常3例脑组织标本未见4-1BBL表达。82例胶质瘤标本31例4-1BBL阳性,阳性表达率为37.8%。统计学提示组织标本中4-1BBL表达与病理级别无明显相关性,与年龄有关(P0.05),4-1BBL阳性患者生存期更长(P0.05)。结论:4-1BBL在部分胶质瘤组织中有表达,其表达对判断胶质瘤患者的预后有一定的参考价值。

Clinical significance of 4-1BBL protein expression in human glioma tissues

AIM: To investigate the expression of 4-1BBL(CD137L) protein in human glioma tissues, and to analyze its clinical significance. METHODS: The expression levels of 4-1BBL protein in 82 human glioma specimens were measured by the method of immunohistochemistry. The correlation of 4-1BBL protein level with histopathologic features and survival time was analyzed. RESULTS: 4-1BBL protein positive cells were observed in human brain astrocytic tumors, which were not found in meningioma and normal brain tissues. In our study, the expression of 4-1BBL protein in 3 cases of normal brain tissues was negative. The expression of 4-1BBL protein in 31 cases of glioma specimens were positive, and total positive rate was 37.8% (31/82). The expression of 4-1BBL protein was related to the survival time and age of the patients, but not related to the pathological grade of glioma. Statistically, the patients with positive expression of 4-1BBL protein had longer survival time (P<0.05). CONCLUSION: Expression of 4-1BBL protein may have reference value to predict the prognosis of patients with glioma.
