The management of hepatocellular carcinoma (HCC) with high tumor burden and major portal vein tumor thrombosis (PVTT) remains a great challenge. The authors aimed to investigate the efficacy and safety of lenvatinib plus drug-eluting bead transarterial chemoembolization (DEB-TACE) and hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin, fluorouracil and leucovorin (Len+DEB-TACE+HAIC) versus lenvatinib plus DEB-TACE (Len+DEB-TACE) for HCC greater than 7.0 cm accompanied with major PVTT.
This multicenter retrospective cohort study evaluated consecutive patients with HCC (> 7.0 cm) and major PVTT who received Len+DEB-TACE+HAIC (Len+DEB-TACE+HAIC group) or Len+DEB-TACE (Len+DEB-TACE group) between July 2019 and June 2021 from eight institutions in China. Objective response rate (ORR), time to progression (TTP), overall survival (OS), and treatment-related adverse events (TRAEs) were compared between the two groups by propensity score matching (PSM).
A total of 205 patients were included. After PSM, 85-paired patients remained in the study cohorts. Patients in the Len+DEB-TACE+HAIC group had higher ORR (61.2% vs. 34.1%, P < 0.001), longer TTP (median, 9.8 vs. 5.9 months, P < 0.001), and prolonged OS (median, 16.7 vs. 12.5 months, P < 0.001) than those in the Len+DEB-TACE group. The ORR and TTP of both intrahepatic tumor (ORR: 64.7% vs. 36.5%, P < 0.001; median TTP: 10.7 vs. 7.0 months, P < 0.001) and PVTT (ORR: 74.1% vs. 47.1%, P < 0.001; median TTP: 17.4 vs. 7.6 months, P < 0.001) were better in the Len+DEB-TACE+HAIC group than the Len+DEB-TACE group. The frequency of grade 3-4 TRAEs in the Len+DEB-TACE+HAIC group were comparable to those in the Len+DEB-TACE group (38.8% vs. 34.1%, P = 0.524).
The addition of HAIC to Len+DEB-TACE significantly improved ORR, TTP, and OS over Len+DEB-TACE with an acceptable safety profile for large HCC with major PVTT.
高肿瘤负荷和主要门静脉肿瘤血栓形成（PVTT）的肝细胞癌（HCC）的管理仍然是一个巨大挑战。作者旨在研究乐伐替尼联合载药微球经动脉化疗栓塞术（DEB-TACE）和奥沙利铂、氟尿嘧啶及亚叶酸钙的肝动脉灌注化疗（HAIC）（Len+DEB-TACE+HAIC）与乐伐替尼联合DEB-TACE（Len+DEB-TACE）治疗直径大于7.0 cm且伴有主要PVTT的HCC的疗效和安全性。
这项多中心回顾性队列研究评估了2019年7月至2021年6月期间来自中国8家机构的连续的HCC（>7.0 cm）和主要PVTT患者，这些患者接受了Len+DEB-TACE+HAIC（Len+DEB-TACE+HAIC组）或Len+DEB-TACE（Len+DEB-TACE组）治疗。通过倾向评分匹配（PSM）比较两组的客观缓解率（ORR）、疾病进展时间（TTP）、总生存期（OS）和治疗相关不良事件（TRAEs）。
共纳入205例患者。PSM后，研究队列中仍有85对患者。Len+DEB-TACE+HAIC组患者的ORR更高（61.2%对34.1%，P<0.001），TTP更长（中位数分别为9.8个月和5.9个月，P<0.001），OS更长（中位数分别为16.7个月和12.5个月，P<0.001），均高于Len+DEB-TACE组。Len+DEB-TACE+HAIC组肝内肿瘤的ORR和TTP（ORR：64.7%对36.5%，P<0.001；中位TTP：10.7个月对7.0个月，P<0.001）以及PVTT的ORR和TTP（ORR：74.1%对47.1%，P<0.001；中位TTP：17.4个月对7.6个月，P<0.001）均优于Len+DEB-TACE组。Len+DEB-TACE+HAIC组3-4级TRAEs的发生率与Len+DEB-TACE组相当（38.8%对34.1%，P=0.524）。
Len+DEB-TACE联合HAIC较Len+DEB-TACE显著提高了ORR、TTP和OS，对于伴有主要PVTT的大型HCC具有可接受的安全性。
