摘    要:目的:探讨粒细胞-巨噬细胞集落刺激因子(GM-CSF)基因修饰的肿瘤细胞疫苗(GM-CSF modified tumor cell vaccine,GVAX)治疗前后黑素瘤患者外周血免疫指标的变化及其对预后的影响。方法:收集2007年10月至2012年12月期间于天津医科大学肿瘤医院接受GVAX治疗的56例黑素瘤患者,采用流式细胞技术检测患者治疗前后外周血CD3+T细胞、CD4+T细胞、CD8+T细胞、调节性T细胞(Treg)、自然杀伤细胞(NK)及树突状细胞(DC1和DC2)的比例,分析治疗前后外周血各免疫细胞比例的变化,并探讨其与患者预后的关系。结果:GVAX治疗后患者外周血CD8+T细胞比例较前升高(37.56±12.76)%vs(34.71±12.30)%,P=0.006],CD4+T细胞比例降低(53.44±13.36)%vs(56.27±13.15)%,P=0.017],CD4+/CD8+比值降低1.61(1.37)vs 1.75(0.71),P=0.009]。治疗后CD3+T、NK、Treg、DC1、DC2与治疗前的差异无统计学意义(P>0.05)。晚期患者GVAX治疗前外周血CD8+T细胞比例大于均值组与小于均值组相比,中位生存时间显著延长(29.16 vs 13.34个月,P=0.012)。结论:GVAX治疗黑素瘤可增强CD8+T细胞为主的抗肿瘤免疫应答,晚期患者外周血CD8+T细胞比例可作为预测GVAX疗效的指标,为判断预后起到一定的提示作用。
