Spots Global Cancer Trial Database for A Clinical Trial Using Irreversible Electroporation for the Treatment of Liver Cancers

Study Description

Brief Summary: Liver cancer including primary hepatocellular carcinoma (HCC) and metastatic liver cancers is one the most common malignancies in the world. Over 10000 new cases per year are diagnosed in Taiwan. Despite the many treatment options, the prognosis of HCC remains dismal. More than 8000 people died of this cancer every year in Taiwan. A majority (70% to 85%) of patients present with advanced or unresectable disease. In contrast, small liver cancers can be cured with an appreciable frequency. Five-year disease-free survival exceeding 50% has been reported for surgical resection, and for the inoperable patients who do not have vascular invasion or extrahepatic spread. Radiofrequency ablation (RFA) is recommended as an alternative curative therapy. However, the main drawback of RFA is its limitation to tumor size and location. The tumors larger than 5 cm in diameter or located adjacent to vessels, could not be ablated completely sometimes.

Detailed Description: Irreversible electroporation (IRE), developed and manufactured by AngioDynamics US Ltd, can ablate tumor by fenestrating the cancer cell membrane by electric pulse. The anti-tumor effect does not result from thermotherapy, so is also not diminished by adjacent vessels. Several pre-clinical studies have already demonstrated IRE is a safe and effective treatment for live cancers. The system has been approved as safe by the European Union (EU) in 2008 and received Food and Drug Administration (FDA) approval in 2010. However, there are still few experiences in using IRE for tumor ablation in Taiwan. In this study, the investigators will perform IRE for 40 inoperable patients with liver cancers adjacent to vessels who are suitable to receive radiofrequency ablation (RFA) in the investigators hospital. The investigators will evaluate the potential side effect and ablate effect of tumors by abdominal computed tomography (CT) or magnetic resonance imaging (MRI), and the investigators will also follow-up this patients for 2 years to evaluate the overall survival and local recurrence rate. The investigators will appraisal the clinical feasibility and advantage of the system by this study.
