Willing to comply with all study procedures 8. Has voluntarily given written informed consent Exclusion Criteria 1. If female, pregnant or breast feeding (females of child-bearing potential must use adequate contraception and must have a negative pregnancy test performed within 7 days prior to inclusion into this study) 2.

Life expectancy \<16 weeks or medically unstable 5. Extrahepatic metastases (except metastases to bone, lymph nodes, and adrenal glands which do not constitute an exclusion criterion), but, see Additional Criteria for the Local Ablation Group, below (Section 4.2 of the study protocol) 6. Patients with known GFR \<30 mL/min/1.73m2 7. PT-INR/PTT \>1.5 times the upper limit of normal (patients on anticoagulation therapy will be allowed to participate provided that no prior evidence exists of an underlying abnormality in anticoagulation) 8. Uncontrolled infections at the time of microtherapy 9. Child-Pugh score \>7 points; in patients receiving anticoagulant therapy: Child-Pugh score \>5 points (INR category not regarded for calculation of the Child-Pugh score) 10. Uncontrolled ascites 11.

History of GI bleeding within 30 days before inclusion into this study 18. History of esophageal varices bleeding which has not been controlled by effective therapy and/or therapy to prevent bleeding recurrence 19. Previous malignancy other than carcinoma in situ of the skin or the cervix uteri within 5 years prior to inclusion 20. History of organ transplant (including prior liver transplantation) 21.
