Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

This study tests the hypothesis that use of the research RFA (Radiofrequency ablation) Physics Library will result in more frequent technical success (complete necrotization of target tissues) compared to ablations conducted without computer guidance.

The RFA Physics Library -- a Planning and Guidance Platform (PGP) (NE Scientific, LLC) -- will be used to support percutaneous liver RFA under CT-guidance by assisting physicians in the identification of ablation targets, assessment of proper ablation probe placement, and projection of the created ablation zones on the CT image.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Patients referred for curative ablation of an HCC by consensus recommendation of the multidisciplinary Liver Tumor Clinic at a 400-bed academic cancer center from June 2018 through December 2021 were considered for participation in the study.

Inclusion criteria :

patient : over 18 years old , ble to provide informed consent, expected survival \>1 year lesion: HCC, \>2 cm in diameter, located \> 1 cm from any other lesion. procedure : completed using the support of the Accublate simulation software.

Treatment: CT-guided RFA with Boston Scientific LeVeen system, RF3000 Generator. .

Prophylactic antibiotic General anesthesia; imaging during suspended ventilation, no PEEP Ablation per manufacturer's protocol. Target : tumor + 5 mm margin Planning, targeting, intraprocedural repositioning, assessment of ablation coverage using software simulation in conjunction with manufacturer's data map.

Tract ablation

Follow-up clinic visit with contrast-enhanced cross-sectional imaging (MRI or CT) at 3 months, then every 3 months x 2 years. Data review for complications, progression of liver disease, evidence of local, regional, or metastatic disease, and additional interventions.

Outcome measures: primary : local tumor progression secondary: hepatic tumor progression
