The purpose of this study is to evaluate the efficacy of ex vivo expanded autologous immune killer cells in treating hepatocellular carcinoma patients in：

1. Reduction of tumor size
2. Reducing the relapse rate: Reducing the frequency of TACE treatment by IKC injections.

This is a phase II/III clinical study. Blood is drawn from the patient and brought to our laboratory for isolation of immune cells. These immune cells are then proliferated over a two week period and used to produce the patented product IKC (Immune Killer Cells). The IKC will then infused back into the patient to treat the cancer. Each patient will receive a total of twelve infusions.

60 patients are anticipated to be recruited. This is a double-arm study, the experimental group will receive IKC treatment along with TACE treatment. The control group will receive only TACE treatment. 30 patients will be randomized into each arm.

Inclusion Criteria:

1. Sign and give written informed consent.
2. Age≧20 years, but<80 years.
3. Hepatocellular carcinoma by CT, MRI, AFP, angiography or cytology/biopsy examinations.
4. Barcelona staging system stage B and C.
5. Never receive TACE treatment and comply with the standard of TACE treatment.
6. Child-Pugh stage A and B.
7. ECOG performance status 0 to 2.

Exclusion Criteria:

1. Participant of other clinical trial within the past 4 weeks of screening period.

2. Receiver of chemotherapy, radiotherapy, immunotherapy, hormone therapy, local tumor therapy, or target therapy within the past 4 weeks of screening period.

3. Carriers of HIV or HTLV within the past 4 weeks of screening period.

4. With Active acute or chronic infection by (investigator's judgement).

5. Other diseases, except hepatocellular carcinoma, which are life-threatening to the patients (by investigator's judgement) for example:
