About

The current standard treatment for intermediate-stage HCC (BCLC stage B) is transcatheter arterial chemoembolization (TACE) alone. The combination of TACE with RFA has also reported to be an effective treatment for HCC. Some prospective studies have shown that TACE combined with RFA have better efficacy than any of them alone for early stage HCC (single tumor ≤5 cm). However, to the investigators' knowledge, there have not been any prospective studies to assess whether TACE combined sequentially with RFA is more effective than TACE alone for the treatment of intermediate-stage HCC. The investigators hypothesized that the combination of TACE and RFA might result in better patient survival than TACE alone. Thus, the purpose of this study was to prospectively compare the effects of sequential TACE-RFA with TACE alone for the treatment of intermediate-stage HCC. Intermediate-stage HCC in this study was defined as 2-3 intrahepatic lessions, largest tumor size 3-7 cm or 4-10 intrahepatic lessions, largest tumor size ≤7 cm; ECOG-PS 0; Child-pugh A or B7; no tumor thrombus or extrahepatic metastases.

1. WBC ≥ 4.0 x 109/L (stable, off any growth factor within 4 weeks of study drug administration)
2. Neutrophils ≥ 1.5 x 109/L (stable, off any growth factor within 4 weeks of study drug administration)
3. Platelets ≥ 60 x 109/L (transfusion to achieve this level is not permitted)

4. Serum albumin ≥ 2.8 g/dL

III.Adequate coagulation function:

a)prothrombin activity ≥ 40%

IV.Adequate renal function:

a)Serum creatinine < 110 μmol/L

Exclusion criteria

• Previous local therapy completed less than 4 weeks prior to the dosing and, if present any related acute toxicity > grade 1
• Any contraindications for TACE/RFA procedure:

I.Impaired clotting test (platelet count < 60000/mm3, prothrombin activity < 40%) II.Renal failure / insufficiency requiring hemodialysis or peritoneal dialysis.
