摘要: 目的 评估中性粒细胞与淋巴细胞比值(NLR)在晚期结直肠癌(CRC)患者化疗疗效及预后的意义。方法 回顾性收集2016年1月—2019年4月期间接受以奥沙利铂为基础的标准一线化疗的晚期不可切除结直肠癌患者50例临床病历资料,并在2个化疗周期后评估化疗疗效;根据入组患者化疗前血液学数据计算中性粒细胞与淋巴细胞比值(NLR),运用受试者工作特征曲线确定的NLR最佳截断值,将患者分为高NLR(≥3.785) 组和低NLR(<3.785) 组,比较高、低NLR与临床病理特征、化疗疗效及无进展生存期(PFS)、总生存期(OS)差异;采用COX回归分析模型分析影响晚期结直肠癌患者PFS、OS的因素。结果 高、低NLR两组肿瘤分化程度(P=0.030)、ECOG评分(P=0.003)、CEA(P=0.011)、CA19-9(P=0.047)比较,差异有统计学意义;高低NLR两组间化疗疗效比较,差异有统计学意义(P<0.001),高NLR组化疗疗效较差;两组中位PFS分别为3.44个月和12.84个月,差异有统计学意义(χ2=39.730,P<0.001),两组中位OS分别为7.59个月和22.32个月,差异有统计学意义(χ2=40.505,P<0.001);Cox回归分析提示NLR高低、CEA水平是PFS、OS的独立预后因素(P<0.05)。结论 高水平NLR与晚期结直肠癌患者化疗疗效不佳和预后不良相关,可作为其化疗疗效及预后监测的指标。

Abstract: Objective To evaluate the value of neutrophil-lymphocyte ratio (NLR) in the chemotherapy curative effect and prognosis of patients with advanced colorectal cancer (CRC). Methods Retrospective collection of clinical data from 50 patients with advanced unresectable colorectal cancer who received oxaliplatin-based standard first-line chemotherapy between January 2016 and April 2019. Chemotherapy curative effect was evaluated following 2 chemotherapy cycles. Calculation of neutrophil to lymphocyte ratio (NLR) based on pre-chemotherapy hematology data. The receiver operating characteristic curve was used to determine the optimal cutoff value of NLR,according to patients who were divided into groups of high NLR(NLR≥3.785)and low NLR(NLR≥3.785).The differences between high and low NLR and clinicopathological features, efficacy of chemotherapy, progression-free survival (PFS), and total survival (OS) were compared. COX regression analysis mode was used to analysis of factors affecting PFS and OS in patients with advanced colorectal cancer. Results The differences in tumor differentiation (P=0.030), ECOG score (P=0.003), CEA (P=0.011), CA19-9 (P=0.047) in the high and low NLR groups were statistically significant. The differences in chemotherapy between the two groups was statistically significant (P<0.001), and the high NLR group was less effective. The median PFS of the high and low NLR groups were 3.44 months and 12.84 months, respectively, and the difference was statistically significant (χ2=39.730, P<0.001). The median OS of the high and low NLR groups was 7.59 months and 22.32 months, respectively, and the difference was statistically significant (χ2=40.505, P<0.001). Cox regression analysis suggested that NLR levels and CEA levels were independent prognostic factors for PFS and OS(P<0.05). Conclusion High-level NLR is associated with poor chemotherapy response and poor prognosis in patients with advanced colorectal cancer, and was used as an indicator of chemotherapy efficacy and prognosis.
