Lenvatinib Plus DEB-TACE With/Without FOLFOX-HAIC for Large HCC With PVTT

Lenvatinib Plus Drug-eluting Bead Transarterial Chemoembolization and Hepatic Arterial Infusion Chemotherapy Versus Lenvatinib Plus Drug-eluting Bead Transarterial Chemoembolization for Large Hepatocellular Carcinoma With Portal Vein Tumor Thrombosis: a Multicenter Retrospective Cohort Study

This multicenter retrospective study evaluated consecutive patients with large HCC and PVTT who received lenvatinib plus DEB-TACE with/without FOLFOX-HAIC between July 2019 and June 2021. Tumor response, time to progression (TTP), overall survival (OS), and treatment-related adverse events (TRAEs) were compared between the two groups.

Consecutive patients with large HCC and PVTT treated with lenvatinib plus drug-eluting bead transarterial chemoembolization (DEB-TACE) and hepatic arterial infusion chemotherapy (HAIC) with oxaliplatin, fluorouracil and leucovorin (Len+DEB-TACE+HAIC) or lenvatinib plus DEB-TACE (Len+DEB-TACE) from July 2019 to June 2021 were screened. Tumor response was evaluated according to modified Response Evaluation Criteria in Solid Tumors (mRECIST). Clinical outcomes, including tumor response, TTP, OS, and TRAEs were compared between the two groups.

Inclusion Criteria:
