NEJM:抗GD2抗体联合GM-CSF、白介素-2和维甲酸治疗成神经细胞瘤

2010-10-01 MedSci原创 MedSci原创

  背景 临床前数据和初步临床数据表明,ch14.18(一种抗肿瘤相关二唾液酸神经节苷酯GD2的单克隆抗体)有抗成神经细胞瘤的活性,并且当ch14.18与粒细胞-巨噬细胞集落刺激因子(GM-CSF)或白介素-2结合时,这种活性被增强。我们进行了一项研究,以确定在多模式强化治疗后,在标准异维a酸治疗基础上增加ch14.18、GM-CSF和白介素-2,是否可改善高危成神经细胞瘤(病人)的转归。  

  背景 临床前数据和初步临床数据表明,ch14.18(一种抗肿瘤相关二唾液酸神经节苷酯GD2的单克隆抗体)有抗成神经细胞瘤的活性,并且当ch14.18与粒细胞-巨噬细胞集落刺激因子(GM-CSF)或白介素-2结合时,这种活性被增强。我们进行了一项研究,以确定在多模式强化治疗后,在标准异维a酸治疗基础上增加ch14.18、GM-CSF和白介素-2,是否可改善高危成神经细胞瘤(病人)的转归。

  方法 诱导治疗和干细胞移植有效的高危成神经细胞瘤的病人,以1:1的比例被随机分配接受标准治疗(6个周期的异维a酸)或免疫治疗(6个周期的异维a酸和5个伴随周期的ch14.18,并交替联合使用GM-CSF与白介素-2)。我们在意向治疗的基础上,比较了免疫治疗组与标准治疗组之间的无事件生存率和总生存率。

  结果 共计226例符合研究入选标准的病人被随机分配到其中一个治疗组。在免疫治疗组中,共52%的病人有3、4或5级疼痛,并分别有23%和25%的病人发生毛细血管渗漏综合征和超敏反应。由于观察到了61%的预期事件数,该研究满足了因(治疗)有效而提前终止的标准。随访持续时间的中位数为2.1年。在无事件生存率(2年时为66%±5%对46%±5%,P=0.01)和总生存率(2年时为86%±4%对75%±5%,P=0.02,没有对中期分析进行校正)方面,免疫治疗优于标准治疗。

  结论 在有高危成神经细胞瘤的病人中,与标准治疗相比,采用ch14.18、GM-CSF和白介素-2进行免疫治疗,与转归显著改善相关。
