中文摘要：

目的：检测FGF2在横纹肌肉瘤组织中的表达并初步探讨其临床病理学意义。方法：应用免疫组织化学法检测FGF2蛋白在45例横纹肌肉瘤组织中的表达。结果：45例横纹肌肉瘤组织中23例FGF2阳性表达,阳性率为51.1%,FGF2蛋白表达水平在不同性别、年龄、预后、组织学类型、肿瘤大小和临床分期间差异无显著性（P〉0.05）。结论：FGF2与横纹肌肉瘤的发生发展存在一定相关性。

英文摘要：

Objective： To investigate the expression of FGF2 in rhabdomyosarcoma and to discuss its clinical patho- logical significance in RMS preliminarily. Methods：Immunohistochemical staining was adopted to detect the expression of FGF2 protein in 45 cases of RMS. Results： The positive expression of FGF2 were 51. 1% （ 23/45 ） , The differences of FGF2 protein expression between the sex,age ,survive ,histology and clinical stage group are of no statistic significance（ P 〉 0.05 ）. Conclusion： FGF2 play a role during the occurrence and development of RMS.
