Hepatocellular Carcinoma Stage I, Radiofrequency Ablation
Conditions
Brief summary
To evaluate the short-term efficacy of novel no-touch combined directional perfusion radiofrequency ablation in the treatment of small hepatocellular carcinoma with cirrhosis.
Detailed description
Liver cancer is the fourth leading cause of cancer-related deaths globally. Hepatocellular carcinoma (HCC) accounts for 70% to 85% of primary HCC and is the leading cause of death in patients with cirrhosis. We developed a novel no-touch combined directional perfusion radiofrequency ablation system.By inserting two or more electrodes around the tumor and activating them simultaneously.The hypertonic saline solution can be directed into the focal tissue from a lateral pore through a tube within the electrode to provide more uniform and thorough necrosis.The maximum ablation volume was increased while the loss of normal tissue in the non-injection direction was reduced, thus reducing the incidence of postoperative complications. Therefore, the purpose of this study was to evaluate the short-term efficacy of novel no-touch combined directional perfusion radiofrequency ablation in the treatment of small hepatocellular carcinoma with cirrhosis.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| The incidence of local tumor progression (LTP) | two-years local tumor progression-free survival | LTP was defined as the appearance of new tumor foci near 2 cm at the ablative margin after the local eradication of all tumor cells with RFA |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Tumor-free survival | two-years tumor-free survival | The tumor did not recur after treatment. |
