Computer-assisted Tumor Ablation for Patients With Liver Cancer

In patients with primary liver cancer arising from the liver cells, several treatment options are available according to the stage of the disease. Thermal ablation is a treatment modality using the deposition of thermal energy via an ablation probe to locally destroy the tumor tissue. It has been accepted as being equally effective as surgical resection in patients with very small tumors, as well as for patients with more advanced disease who are not surgical candidates or who are awaiting liver transplantation. Treatment success of thermal ablation is linked to the completeness of the tumor ablation and thus to the precision with which the ablation probes can be placed within the tumors. In recent years, novel computer-assister technology has been introduced to augment accuracy in ablation probe positioning, and first reports describing the safety and efficiency of these procedures have been described in the literature. However, very few works describe the oncological outcomes of patients when using this technology for thermal ablation. In this study, the investigators aim to describe local tumor control and the oncological follow-up of patients when using computer-assisted technology for thermal ablation of liver cancer.
