目的:本研究探讨中性粒细胞与淋巴细胞比值(neutrophil to lymphocyte ratio,NLR)和血小板与淋巴细胞比值(platelet to lymphocyte ratio,PLR)与接受肝动脉栓塞化疗(transarterial chemoembolization,TACE)肝癌(hepatocellular carcinom...目的:本研究探讨中性粒细胞与淋巴细胞比值(neutrophil to lymphocyte ratio,NLR)和血小板与淋巴细胞比值(platelet to lymphocyte ratio,PLR)与接受肝动脉栓塞化疗(transarterial chemoembolization,TACE)肝癌(hepatocellular carcinoma,HCC)患者术后生存期的相关性。方法:回顾性分析2007年1月至2015年6月中山大学肿瘤防治中心肝胆胰科确诊为肝癌并行TACE治疗的216例患者。研究患者依照NLR和PLR的界值分成两组。分析并比较NLR和PLR在不同随访时间点的受试者工作曲线(ROC)下面积。单因素和多因素分析用于评价NLR和PLR与TACE术后肝癌患者预后的相关性。结果:本研究中位随访时间为431.1 d。全体研究对象1、2、3年生存率分别为61.3%、44.2%和40.5%。中位生存时间为410.5 d。术前NLR<1.77组和术前NLR≥1.77组1、2、3年生存率分别为81.6%、63.0%、45.7%和43.1%、27.0%、19.3%,差异具有统计学意义(P<0.001)。术前PLR<94.62组和术前PLR≥94.62组1、2、3年生存率分别为62.7%、47.0%、37.0%和46.8%、29.0%、18.5%,差异具有统计学意义(P=0.002)。多因素分析显示NLR≥1.77与TACE术后肝癌患者较差预后相关,是肝癌患者TACE治疗后的危险因素。结论:TACE介入术前HCC患者的NLR水平,作为系统炎症的一个反应指标,是影响其预后的危险因素。展开更多
目的探讨乳腺癌患者新辅助化疗(neoadjuvant chemotherapy,NAC)前外周血中性粒细胞与淋巴细胞比值(neutrophil to lymphocyte ratio,NLR)、血小板与淋巴细胞比值(platelet to lymphocyte ratio,PLR)及淋巴细胞与单核细胞比值(lymphocyte...目的探讨乳腺癌患者新辅助化疗(neoadjuvant chemotherapy,NAC)前外周血中性粒细胞与淋巴细胞比值(neutrophil to lymphocyte ratio,NLR)、血小板与淋巴细胞比值(platelet to lymphocyte ratio,PLR)及淋巴细胞与单核细胞比值(lymphocyte to monocyte ratio,LMR)在NAC疗效评估中的价值。方法回顾性研究2018年12月—2020年10月于中国科学技术大学附属第一医院确诊并接受NAC的102例乳腺癌患者的临床资料,以病理完全缓解(pathological complete response,pCR)作为NAC疗效的评判指标,并对化疗前NLR、PLR及LMR水平与pCR的相关性进行单因素和多因素分析。结果在102例乳腺癌患者中,有24例(23.53%)接受NAC后达到pCR。经过单因素和多因素分析,患者的年龄、肿瘤大小、临床分期、ER状态、PR状态、Her-2状态、分子分型以及Ki-67水平与NAC后是否达到pCR无明显相关性(均P>0.05)。Logistic回归分析显示,化疗前外周血NLR、PLR水平与是否达到pCR显著相关(均P<0.05),低NLR组的患者达到pCR率显著高于高NLR组(P=0.010,95%CI:0.145~0.768),低PLR组的患者达到pCR率显著高于高PLR组(P=0.014,95%CI:0.153~0.808);而LMR水平与是否达到pCR无明显相关性(P>0.05)。结论乳腺癌患者NAC前外周血NLR、PLR水平与NAC后是否达到pCR显著相关,对局部晚期乳腺癌NAC治疗有一定的指导价值。展开更多

Areas under the receiver operating characteristic curve were calculated to compare the predictive ability of the indices, together with estimating the sensitivity, specificity and agreement rate.Univariate and multivariate analyses were performed to identify risk factors for overall survival(OS). Propensity score analysis was performed to adjust variables to control for selection bias.RESULTS: Each index could predict OS in gastric cancer patients in univariate analysis, but only PNI had independent prognostic significance in multivariate analysis before and after adjustment with propensity scoring(hazard ratio, 1.668; 95% confidence interval:1.368-2.035). In subgroup analysis, a low PNI predicted a significantly shorter OS in patients with stage Ⅱ-Ⅲ disease(P = 0.019, P < 0.001), T3-T4 tumors(P <0.001), or lymph node metastasis(P < 0.001). Canton score, a combination of PNI, NLR, and platelet, was a better indicator for OS than PNI, with the largest area under the curve for 12-, 36-, 60-mo OS and overall OS(P = 0.022, P = 0.030, P < 0.001, and P = 0.024,respectively). The maximum sensitivity, specificity, and agreement rate of Canton score for predicting prognosis were 84.6%, 34.9%, and 70.1%, respectively.CONCLUSION: PNI is an independent prognostic factor for OS in gastric cancer. Canton score can be a novel preoperative prognostic index in gastric cancer.展开更多
