We examined mortality and recurrence of hepatocellular carcinoma (HCC) among 106 transplant candidates with cirrhosis and HCC who had a potential living donor evaluated between January 1998 and February 2003 at the nine centers participating in the Adult-to-Adult Living Donor Liver Transplantation Cohort Study (A2ALL). Cox regression models were fitted to compare time from donor evaluation and time from transplant to death or HCC recurrence between 58 living donor liver transplant (LDLT) and 34 deceased donor liver transplant (DDLT) recipients. Mean age and calculated Model for End-Stage Liver Disease (MELD) scores at transplant were similar between LDLT and DDLT recipients (age: 55 vs. 52 years, p = 0.21; MELD: 13 vs. 15, p = 0.08). Relative to DDLT recipients, LDLT recipients had a shorter time from listing to transplant (mean 160 vs. 469 days, p < 0.0001) and a higher rate of HCC recurrence within 3 years than DDLT recipients (29% vs. 0%, p = 0.002), but there was no difference in mortality or the combined outcome of mortality or recurrence. LDLT recipients had lower relative mortality risk than patients who did not undergo LDLT after the center had more experience (p = 0.03). Enthusiasm for LDLT as HCC treatment is dampened by higher HCC recurrence compared to DDLT.
我们对106例患有肝硬化和肝细胞癌(HCC)的肝移植候选者进行了研究,这些患者在1998年1月至2003年2月期间于参与成人对成人活体肝移植队列研究(A2ALL)的9个中心接受了潜在活体供体评估。采用Cox回归模型比较了58例活体供体肝移植(LDLT)受者和34例尸体供体肝移植(DDLT)受者从供体评估到死亡或HCC复发以及从移植到死亡或HCC复发的时间。LDLT和DDLT受者移植时的平均年龄和计算得出的终末期肝病模型(MELD)评分相似(年龄:55岁对52岁,p = 0.21;MELD:13对15,p = 0.08)。与DDLT受者相比,LDLT受者从列入名单到移植的时间更短(平均160天对469天,p < 0.0001),3年内HCC复发率高于DDLT受者(29%对0%,p = 0.002),但在死亡率或死亡率或复发的综合结局方面没有差异。在中心有更多经验后,LDLT受者的相对死亡风险低于未接受LDLT的患者(p = 0.03)。与DDLT相比,较高的HCC复发率削弱了人们对LDLT作为HCC治疗方法的热情。
