Transcatheter Arterial Chemoembolization Combined With ICIs Plus MTT After Irradiation Stent Placement in HCC With Main PVTT: a Multicenter Propensity Score Matching Study
Hepatocellular carcinoma (HCC) patients with Vp4 \[main trunk\] portal vein tumor thrombosis (PVTT) face a significantly poor prognosis, and current treatment options provide limited benefits. We aimed to assess the safety and efficacy of transcatheter arterial chemoembolization (TACE) combined with immune checkpoint inhibitors (ICIs) plus molecular targeted therapy (MTT) after irradiation stent placement (ISP) as first line treatment for HCC patients with Vp4 PVTT.
• age ≥18 years old; (2) diagnosis of HCC is confirmed through histological or cytological analysis, as well as clinical features; (3) histologically confirmed or imaging-diagnosed PVTT extending to the main portal vein (Vp4); (4) including at least one measurable intrahepatic lesion according to the Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1; (5) Eastern Cooperative Oncology Group (ECOG) performance status of ≤2; (6) patients received first-line treatment with either ICIs-MTT or an ISP-containing quadruple combination within eight weeks (In the ICIs-MTT group, MTT was administered alongside ICIs. In the ISP-containing quadruple, TIT and ICIs-MTT were given after stent placement and portal vein recanalization, either simultaneously or within eight weeks before or after the ICIs-MTT therapy).
