肝移植术后肿瘤复发的影响

目的 评价肝癌肝移植患者术前外周血中性粒细胞/淋巴细胞比值(NLR)对术后肝癌复发的影响.方法 回顾性分析中山大学第三附属医院76例乙型肝炎相关性肝细胞癌患者临床资料,单因素分析术前最大肿瘤直径、肿瘤数目、血管侵犯、甲胎蛋白(AFP)水平、中性粒细胞/淋巴细胞比值(NLR)、术后最大肿瘤直径、术后肿瘤数目和病理组织学分级等对术后无瘤生存率的影响,有统计学意义的术前单因素进入Cox回归模型多因素分析.结果 1、3、5年的无瘤生存率分别为69.2%、52.7%和50.9%.NLR<2.5和NLR≥2.5(37例)的患者1、3、5年的无瘤生存率分别为81.1%、66.9%、63.3%和56.3%、37.6%、37.6% (P=0.011).单因素分析显示术前最大肿瘤直径>5 cm、肿瘤数目>3、有大血管侵犯、AFP≥400 μg/L和NLR≥2.5影响术后无瘤生存率.Cox回归分析显示肿瘤数目>3、血管侵犯和NLR≥2.5为影响肝癌肝移植术后肿瘤复发的独立危险因素.结论 术前高NLR的肝癌肝移植患者术后肿瘤复发的风险增加.

Abstract：

Objective To analyze the negative impact of preoperative neutrophil-lymphocyte ratio (NLR) on the tumor recurrence of hepatocellular carcinoma (HCC) after orthotopic liver transplantation.Methods The clinical data of HBV (hepatitis B virus)-associated HCC patients undergoing liver transplantation were retrospectively analyzed. Their clinical and pathological risk factors for tumor-free survival were evaluated by univariate analysis. The analysis of Cox multiple regression was performed to determine the parameters of predicting the HCC recurrence. NLR≥2.5 was considered to be elevated.Results A total of 76 patients were identified. Among them, 37 had an elevated NLR. The 1, 3 and 5-year tumor-free survival rates were 69.2%, 52.7% and 50.9% respectively. The disease-free survival for patients with high NLR was significantly worse than that for those with normal NLR (1, 3, and 5 year survivals at 56.3%, 37.6% and 37.6% vs 81.1%, 66.9% and 63.3% respectively;P=0.011). Univariate analysis of factors revealed that tumor size＞5 cm, tumor number＞3, vascular invasion, serumα-fetoprotein level≥400 μg/L and NLR≥2.5 were preoperative predictors of disease-free survival. Cox regression analysis showed that the presence of vascular invasion, tumor number＞3 and NLR≥2.5 were independent prognostic factors of worse disease-free survival.Conclusion An elevated NLR significantly increases the risk for tumor recurrence in HCC patients undergoing liver transplantation.
