This is a multicenter, randomized, parallel controlled study to determine the efficacy and safety of transcatheter arterial chemoembolization (TACE) on downstaging hepatocellular carcinoma beyond University of California, San Francisco (UCSF) criteria.

Inclusion Criteria:

3. Beyond UCSF criteria: Diameter of single HCC lesion is between 6.5 cm and 10 cm; The number of tumors ≤3 with the maximum diameter of 4.5-5cm and the total diameter ≤10cm; Multiple HCC lesions ≤5 nodules, each lesion diameter≤4 cm with a total diameter ≤10 cm. Patients cannot be treated with resection or liver transplantation;
4. Patients with stage Ib，IIa，IIb in China liver cancer staging (CNLC) ;
5. Child-Pugh's grade A or B (no more than 7 score);
6. Eastern Cooperative Oncology Group (ECOG) Performance Status (PS) score of 0-1;
7. Patients with hepatitis B virus (HBV) infection should receive routine antiviral therapy;
8. The function of main organs is normal and meet the following criteria:

1) Outcome of blood routine must meet the following criteria (No blood transfusion or blood products were performed within 4 days, and no g-CSF or other hematopoietic stimulants were used for correction): i. Hemoglobin(HB)≥90 g/L; ii. Absolute neutrophil count (ANC)≥1.5×109/L； iii. Platelet (PLT)≥80×109/L; 2) Outcome of hemal biochemistry examination meet the following criteria: i. Albumin (ALB) ≥29 g/L; ii. Alanine aminotransferase (ALT) and aspartate aminotransferase (AST)<2.5 × upper limit of normal (ULN); iii. Total bilirubin (TBIL) ≤2 × ULN; iv. Serum creatinine (SCr) ≤1.25 × ULN, or endogenous creatinine clearance > 45 ml/min (Cockcroft-Gault formula); 3) Patients who have normal livers with an Remnant Liver Volume (RLV)/Standard Liver Volume(SLV) >20% ; Patients who have cirrhosis with an RLV/SLV>40%; 9. Life expectancy of > 3 months; 10. Patients volunteered to participate in this study and signed informed consent, with good compliance.Exclusion Criteria.

Exclusion Criteria:
