ESMO年会:抗肾细胞癌疫苗研究取得进展

      日前在维也纳召开的欧洲内科肿瘤学会(ESMO)年会上,德国波恩综合肿瘤中心专家施密特-沃尔夫报告说,他们研制的一种疫苗能对晚期肾细胞癌产生更有效的免疫作用。
  据他介绍,已有19例晚期肾细胞癌患者在没有其他更好治疗方法的前提下,接受了这种疫苗的 I/II  期临床试验,其中10人完成了全部疫苗接种计划。结果显示,有7例 患者出现了较好的免疫反应。他们“病情稳定,在继续接受治疗的过程中,生活质量也得到改善”。
  施密特-沃尔夫说,目前他的团队已经准备开展第二阶段临床试验,其他治疗方法都已失效的一些癌症患者将接受测试。这种测试也许能为这些患者提供另外一个与癌症继续抗争的机会。
  据介绍,这种名为“MGN1601 ”的新型癌症疫苗的原理,是激活体内免疫系统识别并抑制恶性肿瘤细胞。施密特-沃尔夫说,这种疫苗由两个活性成分组成:一个是异基因,另一个是合成的免疫调节剂。前者可以抑制那些产生白细胞介素7、白细胞生长因子及细胞表面蛋白等物质的肿瘤细胞,而免疫调节剂则可能激活广泛的免疫反应。
  施密特-沃尔夫认为,新疫苗有局部感染、低烧和皮疹等副作用,在治疗癌症的过程中并不能完全替代手术、放疗、化疗等传统治疗手段,但它能够“成为另一种选择”。
