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。

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.

目的 探讨急性心肌梗死患者入院首次中心粒细胞/淋巴细胞比值(neutrophil/lymphocyte ratio,NLR)与院内主要不良心血管事件(MACE)发生的相关性。方法 回顾分析2016年1月—2016年12月入住我院的急性心肌梗死患者179例,分为发生院内不良事件组(n=46)和未发生组(n=133)。采用单因素及多因素Logistics回归分析评估NLR与MACE风险的相关性。结果 179例患者中,46例患者发生院内MACE。发生院内MACE组患者的淋巴细胞计数低于未发生组(P<0.05),NLR高于未发生组(P<0.05),发生院内MACE组患者入院时的心、肾功能较未发生组差(P<0.05)。单因素回归分析显示,NLR水平与院内MACE发病率相关(OR=1.079,95%CI:1.014～1.147, P＜0.05)。多因素logistic回归分析校正性别、年龄、高血压病史、糖尿病史、Killip II级以上、收缩压、入院首次白细胞、eGFR、超敏C反应蛋白、左室射血分数及多支病变后显示,NLR是院内MACE的独立危险因素(OR=1.182,95%CI:1.034～1.352,P＜0.05);此外,超敏C反应蛋白及LVEF<50也是院内MACE的独立危险因素(P＜0.05)。结论 入院首次高NLR与急性心肌梗死患者发生院内MACE相关,是患者发生院内MACE的独立危险因素。

Objective To explore the correlation between first neutrophil/lymphocyte ratio(NLR) and in-hospital major adverse cardiac events (MACE) in patients with in patients with acute myocardial infarction. Methods Total of 179 patients with acute myocardial infarction in Guangzhou First People's Hospital from Jan 2016 to Dec 2016 were enrolled. MACE was defined as malignant arrhythmia, recurrence of myocardial infarction, target vascular reconstruction, acute left heart failure, stroke, cardiac shock and death.Baseline data and in-hospital clinical adverse events were compared among two groups. All patients were divided into two groups:MACE(+) group and MACE(-) group. Univariate and multivariate logistic regression was used to assess the correlation between NLR and in-hospital MACE. Results In-hospital MACE occurred in 46(25.7%)patients. Univariate logistic analysis showed that NLR was strongly related with MACE incidence(OR=1.079,95%CI:1.014～1.147, P＜0.05). Multivariate logistic regression analysis found that after adjusting other traditional risk factors including female gender, age, hypertension,diabetes, overKillip II grade, systolic blood pressure,first white blood cells after admitted,basic renal dysfunction,Hs-CRP,LVEF and multivessel lesions. NLR was still a significant independent predictor of in-hospital MACE in patients with acute myocardial infarction. Additionally, hs-CRP and LVEF<50% were also associated with in-hospital MACE(P＜0.05). Conclusion NLR is the independent risk factor for in-hospital MACE occurrence in acute myocardial infarction at the early admission.
