Inclusion Criteria:

1. Diagnosis of HCC confirmed clinically or histologically or cytologically. A clinical diagnosis of HCC, using the 2010 Guideline of the American Association for the Study of Liver Diseases requires the presence of hepatic tumor(s) with image findings (e.g. sonography, CT or MRI) compatible with HCC, and no evidence of other gastrointestinal tumors (Bruix [2011] - Guideline, 2010).
2. Solitary hepatic tumor <8 cm in diameter or multifocal disease as evidenced by CT or MRI scan. Tumor volume ≥50% of liver organ or infiltrating HCC should be excluded.
3. Not a candidate for surgical resection or ablation of the tumor.
4. The target lesion must not have been treated previously with local therapy, including TACE. Prior local therapy (radiofrequency ablation, percutaneous ethanol injection, cryoablation, or surgery) to nontarget lesions is acceptable.
5. The subject must have received no more than 2 TACE (n≤ 2) or the previous TACE was performed longer than 2 months before enrollment.
6. Local therapy must have been completed at least 4 weeks before baseline scan.
7. Measurable disease using mRECIST criteria (Appendix A) and RECIST1.1 (Appendix B) criteria. At least 1 measurable lesion must be present.
8. Barcelona Clinic Liver Cancer (BCLC) staging classification B (intermediate stage) (Appendix C).

Exclusion Criteria:

1. 1. Candidate for potential curative therapies (i.e., resection or transplantation).
2. Prior allograft transplantation including liver transplantation.
3. Significant cardiac disease (New York Heart Association Class III or IV; Appendix F).
4. Serious infection requiring treatment with systemically administered antibiotics.
5. Pregnancy or lactation.
6. Expected non-compliance.
7. Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure (New York Heart Association Class III or IV), unstable angina pectoris, cardiac arrhythmia, or psychiatric illness or social situations that would limit compliance with study requirements.
