摘　　要：目的探讨术前肿瘤总体积(TTV)、外周血中性粒细胞与淋巴细胞比值(NLR)及乙型肝炎病毒(HBV-DNA)定量水平对预测HBV相关性肝细胞癌(HCC)术后肿瘤复发的价值。方法回顾性分析行根治性肝癌切除术的180例HCC临床资料,随访并记录患者肿瘤复发及存活情况,计算患者TTV和NLR,通过绘制TTV及NLR的受试者工作特征(Receiver operating characteristic,ROC)曲线确定预测肿瘤复发的相关界值。HBV-DNA界值定为1 000 ng/m L。根据TTV、NLR及HBV-DNA界值分别将患者分为低TTV组和高TTV组、低NLR和高NLR组、低HBV-DNA及高HBA-DNA组,通过生存分析比较各组间无瘤生存率及累积生存率有无差异。结果当预测HCC患者术后肿瘤复发的TTV界值为183.59 cm3时,其灵敏度为0.492,特异度为0.964。NLR的界值为2.215时,其灵敏度为0.637,特异度为0.679。低TTV组、低NLR组与低HBV-DNA组患者的1、2、3年无瘤生存率和累积生存率均分别高于高TTV组、高NLR组与高HBV-DNA组,差异有统计学意义(P<0.05)。TTV>183.59 cm3、术前血清NLR>2.215是影响患者术后肿瘤复发的独立危险因素。结论 TTV、术前NLR为影响HCC术后肿瘤复发的独立危险因素。TTV>183.59 cm3、术前NLR>2.215患者预后较差。Objective To investigate the values of total tumor volume （TTV）, preoperative peripheral blood neutrophil to lymphocyte ratio （NLR）, and hepatitis B virus （HBV-DNA） level in predicting the tumor recurrence of patients with HBV-related hepatocellular carcinoma （HCC） after curative hepatectomy. Methods Clinical data of 180 patients with HBV-related HCC who underwent curative hepatectomy were retrospective- ly analyzed. All patients were followed up after hepatectomy, and their tumor recurrence and survival time were recorded. TTV and NLR were calculated according to the clinical data. Receiver operating characteristic （ROC） curves of TTV and NLR for predicting tumor recurrence were plotted, and the cut-off values were defined,respectively. The cut-off value of HBV-DNA for predicting tumor recurrence after hepatectomy was defined at 1,000 ng/mL in advance. The patients were divided into low TTV group and high TTV group, low NLR group and high NLR group, low HBV-DNA group and high HBV-DNA group respectively according to the cut-off values of Trv, NLR, and HBV-DNA. The differences of disease-free survival and cumulative survival rates between groups were compared with survival analysis. Clinical data were included as the factors influencing patients＇ disease-free survival rates by Cox proportional-hazards regression model. Survival analysis was conducted using Kaplan-Meier method and Log-rank test. Survival prognosis was analyzed using Cox＇s proportional-hazard model. Results When the cut-off value of TrV was defined at 183.59 cm^3, the sensitivity was 0.492, and specificity was 0.964. When the cut-off value of NLR for predicting tumor recur- rence after operation was defined at 2.215, the sensitivity was 0.637, and specificity was 0.679. The 1,2,3-year disease-free survival and cumulative survival rates in low TTV group, low NLR group, and low HBV-DNA group were higher than those in high ＂I-V group, high NLR group, and high HBV-DNA group respectively. The differences were statistically signi
