Abstract

Introduction and Objectives

Autoimmune liver diseases (AILD) are rare causes hepatocellular carcinoma (HCC), and data on the efficacy and tolerability of anti-tumor therapies are scarce. This pan-European study aimed to assess outcomes in AILD-HCC patients treated with tyrosine kinase inhibitors (TKIs) or transarterial chemoembolization (TACE) compared with patients with more common HCC etiologies, including viral, alcoholic or non-alcoholic fatty liver disease.

Materials and Methods

107 patients with HCC-AILD (AIH:55; PBC:52) treated at 13 European centres between 1996 and 2020 were included. 65 received TACE and 28 received TKI therapy. 43 (66 %) were female (median age 73 years) with HCC tumor stage BCLC A (34 %), B (46 %), C (9 %) or D (11 %). For each treatment type, propensity score matching was used to match AILD to non-AILD-HCC on a 1:1 basis, yielding in a final cohort of 130 TACE and 56 TKI patients for comparative analyses of median overall survival (mOS) and treatment tolerability.

Results

HCC-AILD patients showed comparable mOS to controls for both TACE (19.5 vs. 22.1 months, p = 0.9) and TKI (15.4 vs. 15.1 months, p = 0.5). Adverse events were less frequent in AILD-HCC patients than controls (33 % % vs. 62 %, p = 0.003). For TKIs, there were no significant differences in adverse events (73% vs. 86%, p = 0.2) or interruption rates (44% vs. 36 %, p = 0.7).

Conclusions

In summary, this study demonstrates comparable mOS for AILD-HCC patients undergoing local and systemic treatments, with better tolerability than HCC of other causes. TKIs remain important therapeutic options for AILD-HCC patients, particularly given their exclusion from recent immunotherapy trials.

自身免疫性肝病相关肝细胞癌患者姑息治疗的有效性和安全性。
导言和目标:自身免疫性肝病(AILD)是肝细胞癌(HCC)的罕见病因,有关抗肿瘤疗法的疗效和耐受性的数据很少。这项泛欧研究旨在评估接受酪氨酸激酶抑制剂(TKIs)或经动脉化疗栓塞(TACE)治疗的AILD-HCC患者与更常见的HCC病因(包括病毒性、酒精性或非酒精性脂肪肝)患者相比的疗效。65例接受了TACE治疗,28例接受了TKI治疗。43人(66%)为女性(中位年龄为73岁),HCC肿瘤分期为BCLC A(34%)、B(46%)、C(9%)或D(11%)。对于每种治疗类型,均采用倾向评分匹配法将AILD与非AILD-HCC按1:1进行匹配,最终得出130例TACE和56例TKI患者,用于中位总生存期(mOS)和治疗耐受性的比较分析:结果:HCC-AILD患者的TACE(19.5个月 vs 22.1个月,P=0.9)和TKI(15.4个月 vs 15.1个月,P=0.5)中位总生存期与对照组相当。AILD-HCC患者的不良事件发生率低于对照组(33% vs 62%,P=0.003)。对于 TKIs,不良事件(73% vs. 86%,p=0.2)或中断率(44% vs. 36%,p=0.7)没有显著差异:总之,这项研究表明,接受局部和全身治疗的AILD-HCC患者的mOS值相当,耐受性优于其他原因导致的HCC。TKIs仍然是AILD-HCC患者的重要治疗选择,尤其是考虑到近期的免疫疗法试验中没有TKIs。
