肝癌患者肝切除术后再行肝移植与直接行肝移植的疗效评估

目的 评估肝癌患者常规肝切除术后的再行肝移植术与直接行肝移植术的生存状况.方法 2001年4月至2006年3月复旦大学中山医院实施417例肝移植术,其中97例肝癌患者符合Milan标准:71例首次治疗即行肝移植术的患者纳入首次肝移植组;26例因切除术后肿瘤复发(n=20)或肝功能失代偿(n=6)行挽救性肝移植的患者归为挽救性肝移植组.比较两组病例的围手术期相关因素及生存状况.结果 首次肝移植组和挽救性肝移植组行肝移植的年龄(50.0岁vs.49.7岁)、性别及肝硬化病因(乙型肝炎或/和丙型肝炎)无明显差异.挽救性肝移植组行肝癌切除至实施肝移植术的中位时间为2.5年.两组患者的病理分析肿瘤数目(1.37个vs.1.50个)、手术时间(7.92 h vs.8.56 h)、术中失血量(1981.69 ml vs.2626.92 ml)及输血量(1981.69 ml vs.2626.92 ml)差异无统计学意义(P＞0.05).两组肿瘤最大直径(2.81 cm vs.2.05 cm)比较差异有统计学意义(t=2.298,P=0.028).中位随访时间14.63个月,两组总体生存率差异无统计学意义(X2=0.003,P=0.959).结论 移植前的肝肿瘤切除术不增加手术难度和影响生存率.肝癌患者在当前供肝紧缺的情况下,优先考虑肝癌切除.若术后肝癌复发不能切除或肝功能失代偿再实施肝移植术也是有效可行的治疗方案.

Salvage liver transplantation for postoperative tumor recurrence or liver dysfunction in patients of hepatocellular carcinoma

Objective To evaluate salvage liver transplantation(LT)for postoperative tumor recurrence or liver dysfunction in patients of hepatocellular carcinoma(HCC).Methods From April 2001 to March 2006,97 HCC patients with the tumor within Milan Criteria underwent LT as the primary treatment(71 cases)and salvage LT because of after resection tumor recurrence(n=20)or postoperative liver dysfunction(n=6).Perioperative and postoperative parameters and long-term survival were compared between the groups of primary LT and salvage LT.Results The mean age(50.0 years vs.49.7 years),gender,and etiology of liver disease(hepatitis B/C/nonviral)were comparable between the two groups.In the salvage LT group.the mean time between liver resection and LT was 2.50 years.Clinical characteristics such as tumor number(1.37 vs.1.50),operative time(7.92 hours vs.8.56 hours),blood loss (1981.69 ml vs.2626.92 ml)and transfusion(1981.69 ml vs.2626.92 ml)were not statistically different (P＞0.05)between the two groups.The size of largest tumor was significantly different between salvage LT group and the primary LT group(2.81 cm vs.2.05 cm)(t=2.298,P=0.028).By a median follow up of 14.63 months,overall survival after liver transplantation was not different between the 2 groups(X2=0.003.P=0.959).Conclusion In selected patients,liver resection prior to transplantation does not increase the morbidity or impair long.term survival following LT.Therefore.1iver resection prior to transplantation can be integrated with the treatment strategy for HCC.
