Computer Guided Microwave Liver Ablation
NE Scientific INC
Summary
The goal of this clinical trial is to learn if the intraoperative use of a computer guidance software can improve the success of liver tumor ablation in adults. The employed software calculates and displays a simulation of the ablation such that the physician can visualize what portion of the target tumor has, and has not been treated at any point during the procedure. The main questions it aims to answer are: 1) Does the use of the computer guidance software reduce the number of times a tumor is incompletely treated. 2) Does the use of the computer guidance software reduce the rate of local tumor recurrence at 2 year follow-up? 3) Was there an increase or a decrease in medical problems for participants after a procedure where the guidance software was used? Researchers will compare liver tumor treatment using the computer guidance software with an historic control to see if the addition of the guidance software improved the outcomes after an ablation. Participants will: Undergo CT-guided microwave ablation treatment of a liver tumor using computer-assisted simulation. Visit the clinic at one month and then every 3 months for blood tests and a contrast-enhanced CT or MRI imaging study (as per standard of care)
Description
Accublate (NE Scientific, Inc) is a computer-based tumor ablation guidance software that uniquely provides real-time simulation of expected ablation volumes. In a previously reported study of Radiofrequency Ablation, the improved visualization of treated versus untreated target tumor was associated with improved outcomes. This study examines clinical application of the simulation software for microwave ablation (MWA), which will be evaluated in a 24 month two-center clinical trial. At Dartmouth Hitchcock Medical Center (DHMC), and at one other hospital, under IRB approval, adults referred fro…

Interventions
- DeviceComputer-Assisted Microwave Liver Ablation
Computer-assisted image-processing software used intraoperatively to assist in percutaneous thermal ablation. The software performs segmentation and registration of pre-procedural and intraprocedural imaging, and simulates the expected ablation zone based on probe position, applied energy, and adjacent vascular structures. The output is displayed in 3D multiplanar images to be used by the treating physician to assist in planning, targeting, and intraprocedural decision-making regarding adequacy of ablation coverage. After each ablation activation, the treating physician determines registration accuracy and decides whether any additional ablation is required, based on images of the software estimation of what tissues have and have not been treated.
