【摘要】:目的本研究旨在探讨治疗前外周血中淋巴细胞与单核细胞比值(LMR)在接受根治性放化疗的食管鳞癌患者的近期疗效预测与预后评估中的意义。病例与方法回顾性分析2012年1月至2013年12月在山东省肿瘤医院接受根治性放化疗的食管鳞状细胞癌患者162例。分别以外周血淋巴细胞绝对值(ALC)的中位值1.65×109/L、外周血单核细胞绝对值的中位值(AMC)0.48×109/L、外周血淋巴细胞与单核细胞比值(LMR)的中位值4.02为临界值,将患者分为低ALC组(≤1.65×109/L,n=84)和高ALC组(1.65×109/L,n=78);低AMC组(≤0.48×109/L,n=84)和高AMC组(0.48×109/L,n=78);低LMR组(≤4.02,n=81例)和高LMR组(4.10,n=81例),比较低ALC组和高ALC组、低AMC组和高AMC组、低LMR组和高LMR组间患者的临床病理学资料,并分析其与食管癌根治性放化疗后客观临床缓解率、生存等指标的相关性。结果在接受根治性放化疗的食管癌患者中,高ALC组患者的完全缓解率(CR率)明显高于低ALC组患者(p=0.040),高LMR组患者的CR率明显高于低LMR组(p0.001),高AMC组患者与低AMC组患者的CR率未见明显差异(p=0.087)。CR组患者的ALC值明显高于非CR组患者(2.00±0.84 vs.1.69±0.58,p=0.018),CR组的患者的LMR值明显高于非CR组患者(4.89±1.17 vs.3.87±1.29,p0.001),CR组患者的AMC值与非CR组患者的AMC未见明显差异(p=0.052)。多因素回归分析显示LMR值是影响接受根治性放化疗的食管癌患者近期疗效的独立影响因素(p=0.008)。在生存分析中,单因素分析结果显示临床T分期、临床肿瘤分期、近期疗效、ALC和LMR是影响食管癌患者PFS和OS的有意义因素。Cox多因素结果分析显示,临床T分期(p=0.043,HR=0.65;95%CI:0.43-1.00)、临床近期疗效(p=0.006,HR=0.52;95%CI:0.33-0.83)、ALC(p=0.048,HR=1.50;95%CI:1.00-2.22)、LMR(p0.001,HR=1.94;95%CI:1.29-2.91)是影响患者PFS的独立预后因素。临床近期疗效(p=0.027,HR=0.55;95%CI:0.33-0.93)和LMR(p=0.008,HR=1.86;95%CI:1.17-2.95)是影响患者食管癌患者OS的独立预后因素。结论1.治疗前外周血中淋巴细胞绝对值可以作为预测接受根治性放化疗治疗的食管鳞状细胞癌患者PFS的独立影响因素。2.治疗前外周血中LMR值是影响接受根治性放化疗治疗的食管鳞状细胞癌患者近期疗效及预后的独立影响因素。
