A Clinical Trial Using Irreversible Electroporation for the Treatment of Liver Cancers

This is an interventional treatment trial for Hepatocellular Carcinoma focused on measuring Hepatocellular Carcinoma, irreversible electroporation, liver cancer Read More

Inclusion Criteria:

Patients must meet all of the following inclusion criteria to be eligible for this study:

1. The diagnosis of hepatocellular carcinoma (HCC) or metastatic liver cancers with pathologic proven, and the diagnosis of HCC will be made by pathology / cytology or according to the American Association for the Study of Liver Diseases (AASLD) (2010) diagnostic criteria. In brief, Nodules larger than 1 cm found on ultrasound screening of a cirrhotic liver should be investigated further with either tri-phase multidetector computed tomography (CT) scan or dynamic contrast enhanced magnetic resonance imaging (MRI). If the appearances are typical of HCC (i.e., hypervascular in the arterial phase with washout in the portal venous or delayed phase), the lesion should be treated as HCC. If the findings are not characteristic or the vascular profile is not typical, a second contrast enhanced study with the other imaging modality should be performed, or the lesion should be biopsied. Biopsies of small lesions should be evaluated by expert pathologists. Tissue that is not clearly HCC should be stained with all the available markers including cluster of differentiation 34 (CD34), cytokeratin 7 (CK7), glypican 3, heat shock protein 70 (HSP70), and glutamine synthetase to improve diagnostic accuracy.
2. Unsuitable for surgical resection but local ablation is indicated, however, the distance between tumour and vessels is smaller than 5 mm.
3. Have at least one, but less than or equal to 3 tumors,
4. Each tumor must be ≤ 5 cm in diameter,
5. Child-Pugh class A-B,
6. Eastern Cooperative Oncology Group (ECOG) score of 0-1,
7. American Society of Anaesthesiologists (ASA) score ≤ 3,
8. Adequate bone marrow, liver and renal function. Platelet count ≥ 100 K/Μl. Total bilirubin ≦ 2 mg/dL. alanine transaminase (ALT) and aspartate transaminase (AST) < 5 x upper limit of normal. prothrombin time (PT)- international normalized ratio (INR) ≦ 2.0. Serum creatinine ≦ 1.5 x upper limit of normal
9. Prior Informed Consent Form
10. Life expectancy of at least 3 months.
11. The disease status is not suitable to receive surgical resection, percutaneous alcohol injection, transarterial chemoembolization or other standard treatment.
