Uncooled TATO microwave system for liver ablation

Area of Science:

• Hepatobiliary Surgery
• Interventional Radiology
• Oncology

Background:

• Liver cancer, both primary and metastatic, presents significant treatment challenges.
• Minimally invasive ablation techniques are increasingly utilized for liver tumor management.
• Uncooled TATO microwave ablation (MWA) offers a potential advancement in this field.

Purpose of the Study:

• To evaluate the safety and efficacy of uncooled TATO microwave ablation (MWA).
• To assess TATO MWA's performance in treating primary and metastatic liver cancer.
• To determine the reproducibility and clinical outcomes of this MWA technique.

Main Methods:

• Retrospective analysis of percutaneous liver ablations performed using TATO MWA.
• Study included 25 ablations: 11 for hepatocellular carcinoma and 14 for metastases (colorectal, gastric, pancreatic).
• Data collected on adverse events and local tumor control rates.

Main Results:

• A single adverse event (4%) reported: an abscess successfully treated with drainage and antibiotics.
• High local tumor control rate of 92% achieved at the 3-month follow-up.
• Satisfactory technical and clinical outcomes were observed across the procedures.

Conclusions:

• Uncooled TATO MWA is a safe and effective treatment modality for primary and secondary liver cancer.
• The technique demonstrates high reproducibility, making it a reliable option for liver tumor ablation.
• TATO MWA offers promising results with good patient outcomes.
