摘要: 目的 研究胶质细胞源性神经营养因子(GDNF)及 GDNF 受体α1(GFRα1)在小儿肾母细胞瘤中的表达及其临床意义。方法 应用免疫组织化学法检测 GDNF 及其受体 GFRα1 30 例小儿肾母细胞瘤组织及 16 例瘤旁正常肾组织病理石蜡标本中的表达。结果 GDNF 在肾母细胞瘤中的阳性表达率高于瘤旁正常肾组织(66.7% vs6.3%,GFRα1 在肾母细胞瘤中的阳性表达率高于瘤旁正常肾组织(63.3% vs 6.3%); 两者在上皮型和胚芽成分强烈表达, 在间叶成分表达较弱。GDNF 及其受体 GFRα1 在不同组织分型、 临床分期及有无淋巴结转移的患者间表达差异无统计学意义。结论 肾母细胞瘤中 GDNF 及其受体 GFRα1 的高表达可能与肿瘤的发生密切相关。

Abstract: Objective To investigate the expressions of GDNF and GFRα1 in childhood nephroblastoma, and therefore its clinical significance. Methods The expression levels of GDNF and GFRα1 were examined by immunohistochemistry of 30 parrafin samples from nephroblastoma section as well as 16 parrafin samples of peritumor renal tissue. Results The positive expression rate of GDNF and GFRα1 in nephroblastoma were higher than those in normal renal tissue66.7% vs 6.3%;63.3% vs 6.3%. GDNF and GFRα1 were strongly expressed in epithelium and embryo bud, but weakly expressed in lobus intermedius of nephroblastoma. There was no correlation between the expressions of GDNF and GFRα1 with histological types, clinical stage and metastasis of nephroblastoma of patients. Conclusion High expression of GDNF and GFRα1 in childhood nephroblastoma might indicate its role in tumor development.
