Transarterial chemoembolization is the standard treatment for patients with intermediate-stage hepatocellular carcinoma (HCC) according to the Barcelona Clinic Liver Cancer staging system. However, in Japan, not a few patients with intermediate-stage HCC undergo liver transplantation (LT). The present study investigated characteristics and outcomes of LT for intermediate-stage HCC. Between February 1999 and November 2016, a total of 226 patients underwent LT for HCC at our institute. Among these, 56 patients showed intermediate-stage HCC (24.8%). We examined overall survival and recurrence rate after LT according to our extended criteria (maximum size ≤5 cm, number ≤10, des-gamma-carboxy prothrombin ≤400 mAU/mL) and pretreatment. One-, 3-, and 5-year overall survival and recurrence rates of LT for intermediate-stage HCC were 88/64/58% and 22/34/44%, respectively. One-, 3-, and 5-year overall survival and recurrence rates in patients within ( = 35) the criteria (94/80/80% and 9/15/22%, respectively) were significantly better than those in patients beyond ( = 21) the criteria (81/43/29%, = 0.002 and 39/41/66%, = 0.001, respectively). Forty-nine cases (88%) had a history of pretreatment. In patients within our extended criteria, overall survival and recurrence rates did not differ significantly between patients with ( = 31) and without ( = 4) pretreatment. In conclusion, outcomes after LT for intermediate-stage HCC are more favorable if patients meet our extended criteria.
根据巴塞罗那临床肝癌分期系统,经动脉化疗栓塞术是中期肝细胞癌(HCC)患者的标准治疗方法。然而,在日本,不少中期HCC患者接受了肝移植(LT)。本研究调查了中期HCC患者肝移植的特征和结局。1999年2月至2016年11月,我院共有226例患者接受了HCC肝移植。其中,56例患者为中期HCC(24.8%)。我们根据扩展标准(最大直径≤5 cm、数量≤10个、异常凝血酶原≤400 mAU/mL)和预处理情况,检查了肝移植后的总生存率和复发率。中期HCC肝移植的1年、3年和5年总生存率及复发率分别为88%/64%/58%和22%/34%/44%。符合标准(n = 35)的患者1年、3年和5年总生存率及复发率(分别为94%/80%/80%和9%/15%/22%)显著优于不符合标准(n = 21)的患者(分别为81%/43%/29%,P = 0.002和39%/41%/66%,P = 0.001)。49例(88%)患者有预处理史。在符合我们扩展标准的患者中,有(n = 31)和无(n = 4)预处理史的患者总生存率和复发率无显著差异。总之,如果患者符合我们的扩展标准,中期HCC肝移植后的结局更有利。
