摘　　要：目的探讨阳性淋巴结比(LNR)和阳性淋巴结对数比(LODDS)对结直肠癌患者预后判断的价值。方法选取2017年1月至2018年12月在江苏大学附属武进医院诊断为结直肠癌并行根治性手术的患者206例,回顾性分析临床病理资料,并进行术后随访。分析LNR和LODDS与临床病理变量的关系,受试者工作特征(ROC)曲线比较阳性淋巴结数量(pN)、LNR、LODDS三种淋巴结分期对结直肠癌复发和生存评估的准确性。结果患者总体生存率与年龄、肿瘤部位、肿瘤分化程度、肿瘤大小、术后是否接受辅助治疗、肿瘤浸润程度(T)、淋巴结分期(N)、远处转移(M)、TNM分期、住院时间、LNR和LODDS分期均显著相关(P<0.05)。影响结直肠癌术后生存的独立因素是肿瘤分化程度、淋巴结转移、远处转移、TNM分期、LNR分期和LODDS分期(均P<0.01)。ROC曲线结果显示,pN、LNR、LODDS分期对复发(无瘤生存期)影响的曲线下面积分别为0.748、0.739、0.733,对总生存期影响的曲线下面积分别为0.739、0.725、0.720(P<0.001)。结论LNR和LODDS显著影响结直肠癌患者总体生存率,是影响结直肠癌术后生存的独立因素,故可作为pN分期不足时的有效补充,且LNR优于LODDS。Objective To investigate the value of positive lymph node ratio(LNR)and log odds of positive lymph nodes(LODDS)in the prognosis of colorectal cancer patients.Methods A total of 206 patients who underwent radical surgery for colorectal cancer in Wujin Hospital Affiliated to Jiangsu University from January 2017 to December 2018 were retrospectively analyzed and followed up after surgery.The relationship between LNR and LODDS and clinicopathological variables was analyzed.The accuracy of positive lymph node number(pN),LNR,and LODDS stage was used in evaluating the recurrence and survival of colorectal cancer using the receiver operating characteristic(ROC)curve.Results The overall survival rate of colorectal cancer patients was significantly correlated with age,tumor location,degree of tumor differentiation,tumor invasion degree,tumor size,postoperative adjuvant therapy,the number of lymph node metastases(N),distant metastases(M),tumor TNM stage,length of hospital stay,LNR and LODDS stage(P<0.05).The independent factors affecting the survival of colorectal cancer after surgery were degree of tumor differentiation,lymph node metastasis,distant metastasis,TNM stage,LNR stage and LODDS stage(all P<0.01).The results of ROC curve showed that the area under the curve of pN,LNR and LODDS stages on recurrence(tumor free survival)were 0.748,0.739 and 0.733,respectively,and the area under the curve for the effect on overall survival were 0.739,0.725 and 0.720,respectively(P<0.001).Conclusions LNR and LODDS significantly affect the overall survival rate of colorectal cancer patients,and they are independent factors affecting the survival of colorectal cancer after surgery.Therefore,they can be used as effective supplements when pN stage is insufficient,and LNR is better than LODDS.
