               [摘   要] 目的:探讨术前及术后乳酸脱氢酶(lactate dehydrogenase LDH)与白蛋白比值(LDH/albumin ratio,LAR)的动态变化
                对结肠癌预后的评估价值。方法:回顾性收集 2013 年 1 月—2016 年 12 月间在江南大学附属医院胃肠外科接受手术治疗的
                134例结肠癌患者,收集患者临床病理特征,包括性别、年龄、TNM分期等,计算患者手术前及手术后1周以内的LAR值,采用
                受试者工作特征(receiver operating characteristic,ROC)曲线确定最佳截断值,利用生存分析中的 Kaplan⁃Meier 法绘制生存曲
                线,Log⁃rank检验进行单因素分析及Cox多因素回归分析法进行多因素分析。结果:根据术前LAR和术后LAR各自的最佳截
                断值,将134例患者分别分为术前高LAR组和术前低LAR组,术后高LAR组和术后低LAR组。术前高LAR 组、术前低LAR组
                的患者 5 年总生存(overall survival,OS)率分别为 42.9%和 84.9%,5 年无进展生存(progression⁃free survival,PFS)率为 45.5%和
                82.6%;术后高 LAR 组、术后低 LAR 组的患者5 年OS率分别为 62.5%和 81.9%,5年PFS率分别为70.0%和77.3%。将术前、术
                后 LAR 联合分析,134 例患者进一步分为 3 个组,分别为 LAR1 组(术前和术后 LAR 均高)、LAR2 组(术前或术后 LAR 高)、
                LAR3组(术前和术后LAR均低)。单因素及多因素分析显示,LAR1组、LAR2组、LAR3组患者5 年OS率分别为 33.3%、78.1%、
                84.5%,差异具有统计学意义(P<0.01);淋巴结转移与患者 OS、PFS 显著相关(P<0.01),临床分期与患者 PFS 显著相关(P<
                0.01)。结论:联合检测术前LAR和术后LAR动态变化有助于判断结肠癌的预后,术前和术后LAR两者均高是结肠癌患者OS
                独立的预后不良因素。

               [Abstract] Objective:This study aims to investigate the value of preoperative and postoperative changes in lactate dehydrogenase
               (LDH)to albumin ratio(LDH/albumin ratio,LAR)in assessing the prognosis of colon cancer. Methods:The clinical data of 134 colon
                cancer patients who underwent gastroenterology surgery at Jiangnan University Hospital from Jan. 2013 to Dec. 2016 were collected.
                Patients’clinical pathological characteristics were collected,including gender,age,TNM staging,etc. to calculate the LAR values
                before and within one week after surgery and to determine the optimal cut⁃off value by using the receiver operating characteristic curve
               (ROC). Kaplan⁃meier method of survival analysis was used to draw the survival curve,Log⁃rank test to perform univariate analysis and
                Cox multivariate regression analysis to conduct multivariate analysis. Results:According to the optimal cut⁃off values of preoperative
                and postoperative LAR,134 patients were divided into preoperative high⁃LAR group,preoperative low⁃LAR group,postoperative high⁃
                LAR group and postoperative low⁃LAR group. The 5⁃year overall survival(OS)rate was 42.9% in the preoperative high⁃LAR group and
                84.9% in the preoperative low⁃LAR group,and the 5⁃year progression⁃free survival(PFS)rate was respectively 45.5% and 82.6%;
