BMC Cancer:患者来源胃癌异种移植是一种有效的靶向治疗的临床前评价工具

2017-03-28 MedSci MedSci原创

靶向治疗是胃癌(GC)的新兴治疗方案。患者来源的肿瘤异种移植物(PDX)模型GC保留了原始临床癌症的特征,为临床前药物疗效测试提供了强大的工具。该研究旨在建立PDX GC模型,并探索靶向Her2,MET(cMet)和FGFR2的治疗方法,这可能有助于医生为选定的患者选择适当的靶向治疗。

近日,来自浙江大学医学院附属第一医院的研究人员通过构建人源化肿瘤异种移植模型进行了胃癌靶向药物筛选,相关研究成果刊登于国际杂志BMC Cancer上,该研究为开发新的胃癌靶向治疗药物提供了重要信息。

靶向治疗是胃癌(GC)的新兴治疗方案。患者来源的肿瘤异种移植物(PDX)模型GC保留了原始临床癌症的特征,为临床前药物疗效测试提供了强大的工具。该研究旨在建立PDX GC模型,并探索靶向Her2METcMet)和FGFR2的治疗方法,这可能有助于医生为选定的患者选择适当的靶向治疗。

研究人员收集了32名病人的胃癌组织,移植到免疫缺陷小鼠体内,并借助多种实验技术对Her2cMetFGFR2的表达水平进行了评估。最后利用构建的PDX模型检测靶向抑制剂的抗肿瘤效果。

研究表明,这些PDX GC模型为药物筛选和评估提供了理想的平台。具有阳性cMetFGFR2基因扩增的GC患者可能潜在地受益于cMetFGFR2靶向治疗或组合靶向治疗。
