目的:观察GM-CSF基因修饰的肿瘤细胞疫苗(GM-CSF modified tumor cell vaccine,GVAX)治疗前后肺癌患者外周血中CD4+CD25+调节性T细胞(regulatory T cell,Treg)比例的变化,探讨其与肺癌临床病理特征的关系及对患者生存的影响。方法:选择2007年3月至2010年7月天津医科大学附属肿瘤医院接受GVAX治疗的85例肺癌患者,其中鳞癌28例、腺癌47例、小细胞癌10例,早期(Ⅰ~ⅢA期)23例、晚期(ⅢB~Ⅳ期)62例。流式细胞术检测患者GVAX治疗前后外周血Treg的比例,分析治疗前后Treg比例变化与肺癌临床病理特征和患者生存期的关系。结果:接受GVAX治疗的85例肺癌患者1、3年的生存率分别为69.3%、48.2%,治疗后外周血Treg比例明显下降[(4.86±2.52)%vs(5.52±2.68)%,P<0.05]。患者血清LDH水平正常组治疗后Treg比例明显下降[(4.50±2.23)%vs(5.59±2.76)%,P<0.05],而LDH增高组治疗后Treg比例上升[(6.04±3.07)%vs(5.31±2.48)%,P<0.05];...
