摘要 目的探讨胃癌根治术后化疗对患者外周血辅助性T淋巴细胞1(Th1)和辅助性T淋巴细胞2(Th2)比率(Th1/Th2)的影响及其临床意义。方法采用流式细胞技术检测26例胃癌患者行胃癌根治术后化疗开始前、胃癌根治术后化疗第1周期、第2周期及第3周期结束时外周血中Th1类细胞因子(白介素-2、干扰素γ、肿瘤坏死因子)和Th2类细胞因子(白介素4、白介素6、白介素10)的表达水平。结果与胃癌根治术后化疗开始前相比,胃癌根治术后化疗第1周期结束时外周血Th1、Th2表达水平,差异有统计学意义(P<0.05);与胃癌根治术后化疗开始前及化疗第1周期结束时相比,第2、3周期化疗结束时外周血Th1表达水平显著增强,差异均有统计学意义(P<0.05),Th2表达水平显著降低,差异均有统计学意义(P<0.05);胃癌根治术后2、3化疗周期结束时Th1、Th2表达水平无明显改变(P>0.05)。结论胃癌根治术后化疗第1周期结束时,Th1、Th2表达被抑制,细胞免疫能力下降;随着化疗周期的延长,Th1/Th2平衡重新建立,机体的肿瘤免疫状态显著增强,并逐渐趋于稳定。
