Hepatocellular carcinoma (HCC) is one of the most commonly malignant tumors around the world. Hepatic resection or liver transplantation is the radical method to cure the disease. However, due to multiple tumors or poor hepatic function reserve in cirrhosis, surgical treatment is suitable for early-stage and well reserved liver function patients. Therefore, in clinical practice, transarterial chemoembolization (TACE) is a preferential and standard treatment of unresectable HCC. TACE has been proved to provide outstanding efficacy for treating advanced stage HCC patients. However, TACE is associated with a high rate of treatment failure for advanced HCC patients. EACH trial opened the door to FOLFOX-based system chemotherapy for advanced HCC patients. Recently, investigators have showed that hepatic arterial infusion of FOLFOX-based chemotherapy (HAIC) was safe and efficient for advanced HCC patients. The combination of TACE with HAIC (TACE-HAIC) was proved to increase the local doses of chemotherapeutic agents in the liver, reduce the viability of HCC cells and increase the hepatectomy rate in our previous study.

Levatinib is a new treatment and offers relative high overall response rate for advanced HCC, which was approved in China and Japan. However, whether the combination of TACE-HAIC and Lenvatinib would increse tumor control for unresectable patients is still unknown. Thus, this single arm, phase 2 study is designed to analyze the safety and efficacy TACE-HAIC plus Lenvatinib for patients with unresectalbe HCC.
