Abstract

BACKGROUND

New guidelines propose a minimum 5-year survival of 60% for hepatocellular carcinoma (HCC) with living donor liver transplantation (LDLT). This study aimed to evaluate the 5- and 10-year survival rates after transplantation for the expanded criteria for HCC.

METHODS

This single-center retrospective cohort study included 208 patients who underwent LDLT for the expanded criteria (the largest tumor diameter of ≤10 cm, any tumor number, and alpha-fetoprotein [AFP] level of <1000 ng/mL) and analyzed 5- and 10-year overall survival (OS) and recurrence risk (RR) rates.

RESULTS

With a median follow-up of 65.1 months (IQR, 19.1-80.2), the 5- and 10-year OS and RR rates were 67.0% and 61.0% and 20.5% and 22.5%, respectively. The largest tumor diameter of >6 cm (hazard ratio [HR], 3.7; 95% CI, 1.7-8.2; P = .001) and AFP level of >400 ng/mL (HR, 4.0; 95% CI, 1.8-9.0; P = .001) were predictors of recurrence. Patients outside the Milan criteria (MC) were grouped into low- and high-risk HCC based on tumor size and AFP level. For low-risk HCC (tumor size of <6 cm, any tumor number, and AFP level of <400 ng/mL), the 5-year RR was comparable to the MC and increased the transplant pool by 35.7% (P > .5). The median number of tumors and the rate of microvascular invasion in the high-risk group, low-risk group, and MC were 2.0 (1.0-3.2), 4.0 (2.0-5.0), and 1.0 (1.0-2.0) (P < .001) and 72.2% (13/18), 44.0% (22/50), and 22.8% (32/140) (P < .001), respectively.

CONCLUSION

The expanded criteria met the benchmark for 5-year survival. LDLT for the low-risk HCC in the expanded criteria was associated with an acceptable RR.

摘要

背景

新指南提出活体肝移植（LDLT）治疗肝细胞癌（HCC）的最低5年生存率为60%。本研究旨在评估扩大标准的HCC患者移植后的5年和10年生存率。

方法

这项单中心回顾性队列研究纳入了208例因扩大标准（最大肿瘤直径≤10 cm、肿瘤数量不限、甲胎蛋白[AFP]水平<1000 ng/mL）接受LDLT的患者，并分析了5年和10年总生存率（OS）及复发风险（RR）率。

结果

中位随访时间为65.1个月（四分位间距，19.1 - 80.2），5年和10年的OS率分别为67.0%和61.0%，RR率分别为20.5%和22.5%。最大肿瘤直径>6 cm（风险比[HR]，3.7；95%置信区间，1.7 - 8.2；P = 0.001）和AFP水平>400 ng/mL（HR，4.0；95%置信区间，1.8 - 9.0；P = 0.001）是复发的预测因素。米兰标准（MC）以外的患者根据肿瘤大小和AFP水平分为低风险和高风险HCC。对于低风险HCC（肿瘤大小<6 cm、肿瘤数量不限、AFP水平<400 ng/mL），5年RR与MC相当，且移植供体池增加了35.7%（P > 0.5）。高风险组、低风险组和MC组的肿瘤中位数及微血管侵犯率分别为2.0（1.0 - 3.2）、4.0（2.0 - 5.0）和1.0（1.0 - 2.0）（P < 0.001）以及72.2%（13/18）、44.0%（22/50）和22.8%（32/140）（P < 0.001）。
