Abstract

目的 研究肝细胞生长因子(HGF)、肝细胞生长因子受体(c-Met)、增殖细胞核抗原(PCNA)、CD34在胶质瘤的表达,并结合多种临床因素探讨其与肿瘤恶性程度及预后的关系.方法用原位杂交法检测68例胶质瘤中HGF、c-Met mRNA的表达,用SP免疫组化技术检测PCNA、CD34在肿瘤中的表达,并对可能影响预后的因素进行统计学分析.结果胶质瘤HGF、c-Met、PCNA的表达在高低级别组之间存在显著差异(P<0.05).Logistic逻辑回归单因素分析显示,患者年龄、切除范围、恶性程度、术前KPS评分、瘤周水肿、术后放疗、HGF表达、C-Met表达、PCNA表达、MVD对3年存活率有意义;多因素分析表明,肿瘤的恶性程度、术前KPS评分、MVD、PCNA及c-Met基因的表达是影响预后的主要因素.结论HGF、c-Met、PCNA在胶质瘤中的表达与其恶性程度相关,肿瘤的恶性程度、术前KPS评分、MVD、PCNA及c-Met基因的表达可作为考察胶质瘤患者预后的重要指标。
