  新一期英国《自然-医学》杂志刊登报告说,德国研究人员对一种肾癌疫苗进行了人体临床试验,结果显示它安全有效,与化学疗法相比效果更好,并且副作用更少。

  德国蒂宾根大学等机构的研究人员报告说,这种代号为IMA901的疫苗可以促使人体自身免疫系统抵抗癌症。研究人员对96名肾癌患者展开了临床试验,结果显示疫苗安全,没有太大的副作用,与最新的化疗相比可更好地延长患者的生命。

  化疗是治疗癌症的常用方法,它的原理是利用化学药物毒杀癌细胞,但药物也会“误伤”一些健康细胞,副作用较大。而本次试验的疫苗是促进人体自身免疫系统攻击癌细胞,副作用较小。

  进行研究的汉斯-格奥尔格·赖门泽教授说,这项研究成果在癌症免疫疗法方面具有重要意义,因为它证明了利用人体自身免疫系统治疗癌症的可行性,而这是一个可用于所有癌症治疗的原则。他和同事还正在研究用类似方法来治疗肝癌和卵巢癌等其他癌症。
