This is an single center, randomized controlled trial to evaluate the efficacy and safety of TACE-Len-I compared with TACE-Len for the treatment of HCC with branch PVTT.~171 HCC patients with branch PVTT will be enrolled in this study. The Patients will be treated with TACE-Len-I or TACE-Len using an 2:1 randomization scheme.~TACE will be performed for the patients after randomization. Lenvatinib (body weight ≥ 60 kg, 12mg P.O. QD; body weight < 60 kg, 8mg P.O. QD) will be started at 3-7 days after the first TACE and last until disease progresses, intolerable toxicity, withdrawal of informed consent, loss of follow-up, death, or other circumstances that require termination of treatment, whichever occurs first. For patients in the TACE-Len-I arm, iodion-125 seeds will be implanted into the PVTT (according to the pre-operative planning) under CT guidance within 14 days after the first TACE. TACE and iodion-125 seeds implantation can be repeated on demand during follow-up based on the evaluation of laboratory and imaging examination.
This study is conducted to evaluate the efficacy and safety of transarterial chemoembolization (TACE) combined with lenvatinib and iodion-125 seeds brachytherapy (TACE-Len-I) compared with TACE combined with lenvatinib (TACE-Len) for hepatocellular carcinoma (HCC) with portal vein branch tumor thrombus (branch PVTT).
