Abstract

Background: Liver transplantation (LT) for alcohol-associated liver disease (ALD) is increasing and may impact LT outcomes for patients listed for HCC and other indications.

Methods: Using US adults listed for primary LT (grouped as ALD, HCC, and other) from October 8, 2015, to December 31, 2021, we examined the impact of center-level ALD LT volume (ATxV) on waitlist outcomes in 2 eras: Era 1 (6-month wait for HCC) and Era 2 (MMaT-3). The tertile distribution of ATxV (low to high) was derived from the listed candidates as Tertile 1 (T1): <28.4%, Tertile 2 (T2): 28.4%-37.6%, and Tertile 3 (T3): >37.6% ALD LTs per year. Cumulative incidence of waitlist death and LT within 18 months from listing by LT indication were compared using the Gray test, stratified on eras and ATxV tertiles. Multivariable competing risk regression estimated the adjusted subhazard ratios (sHRs) for the risk of waitlist mortality and LT with interaction effects of ATxV by LT indication (interaction p).

Results: Of 56,596 candidates listed, the cumulative waitlist mortality for those with HCC and other was higher and their LT probability was lower in high (T3) ATxV centers, compared to low (T1) ATxV centers in Era 2. However, compared to ALD (sHR: 0.92 [0.66-1.26]), the adjusted waitlist mortality for HCC (sHR: 1.15 [0.96-1.38], interaction p = 0.22) and other (sHR: 1.13 [0.87-1.46], interaction p = 0.16) were no different suggesting no differential impact of ATxV on the waitlist mortality. The adjusted LT probability for HCC (sHR: 0.89 [0.72-1.11], interaction p = 0.08) did not differ by AtxV while it was lower for other (sHR: 0.82 [0.67-1.01], interaction p = 0.02) compared to ALD (sHR: 1.04 [0.80-1.34]) suggesting a differential impact of ATxV on LT probability.

Conclusions: The high volume of LT for ALD does not impact waitlist mortality for HCC and others but affects LT probability for other in the MMAT-3 era warranting continued monitoring.

酒精相关肝病移植手术激增对肝癌和其他适应症移植手术的影响。

背景：因酒精相关性肝病（ALD）而接受肝移植（LT）的患者越来越多，这可能会影响因 HCC 和其他适应症而接受 LT 的患者的治疗效果：因酒精相关性肝病（ALD）而进行的肝移植（LT）正在增加，这可能会影响因HCC和其他适应症而入院的患者的LT结果：方法：我们使用2015年10月8日至2021年12月31日期间列入初治LT（按ALD、HCC和其他分组）的美国成人患者，研究了2个时代中心水平的ALD LT数量（ATxV）对候诊结果的影响：时代 1（HCC 等待 6 个月）和时代 2（MMaT-3）。ATxV的阶梯分布（从低到高）由列出的候选者得出，即阶梯1（T1）：每年37.6%的ALD LT。使用格雷检验比较了LT适应症的候补死亡累积发生率和列名后18个月内的LT发生率，并按年代和ATxV三等分进行了分层。多变量竞争风险回归估算了候补死亡和LT风险的调整后次危险比（sHRs），以及ATxV与LT适应症的交互作用（交互作用p）：结果：与第二纪元中的低ATxV中心（T1）相比，在56,596名候选者中，高ATxV中心（T3）的HCC和其他候选者的累计候诊死亡率更高，LT概率更低。然而，与 ALD（sHR：0.92 [0.66-1.26]）相比，HCC（sHR：1.15 [0.96-1.38]，交互作用 p = 0.22）和其他（sHR：1.13 [0.87-1.46]，交互作用 p = 0.16）的调整后候诊死亡率没有差异，表明 ATxV 对候诊死亡率没有不同的影响。HCC的调整后LT概率（sHR：0.89 [0.72-1.11]，交互作用 p = 0.08）与ALD（sHR：1.04 [0.80-1.34]）相比没有差异，而其他（sHR：0.82 [0.67-1.01]，交互作用 p = 0.02）则较低，这表明ATxV对LT概率有不同的影响：结论：在MMAT-3时代，ALD的大量LT不会影响HCC和其他患者的候诊死亡率，但会影响其他患者的LT概率，因此需要继续监测。
