The purpose of this study is to determine the technical success rate of creating a safety margin of 5 mm or more including the tumor by performing image-guided percutaneous microwave thermal therapy using a microwave generator and antenna developed by StarMed for the treatment of small liver cancer and the 1-year local recurrence rate based on follow-up imaging tests.
Child-Pugh Class A or B
Patients with suspected hepatocellular carcinoma or residual/recurrent hepatocellular carcinoma of 4 cm or less on MDCT, CEUS, or MRI performed within the last 60 days or Patients with suspected metastatic liver cancer of 4 cm or less on MDCT, CEUS, or MRI performed within the last 60 days, for whom microwave thermal ablation is being considered
In cases where there are three or more malignant liver tumors
When the maximum size of the tumor exceeds 4 cm
Diffuse infiltrative type of cancer with unclear tumor boundaries
When the tumor is adhered to the central hepatic portal vein, hepatic vein, or bile duct by 5 mm or more
