Radiofrequency Ablation (RFA) of Liver Tumors

Radiofrequency ablation (RFA) is a new technique for the treatment of cancer that began in the liver or cancer that spread to the liver from another organs as well as inoperable liver cancer. The procedure is not complicated, with only few side effects, utilizing thermal ablation to destroy the target tissue via a needle.
The radiofrequency ablation equipment normally consists of radiofrequency (RF) energy generator, radiofrequency needle and ground pad. The radiofrequency energy generator and the types of radiofrequency needle have been designed differently based on each manufacturer, but with the same purpose to transmit thermal energy into the cancerous liver tumor thoroughly.

  • Patients with not more than 3 tumors, each less than 5 centimeters in diameter.
  • Treatment for tumor begun in the liver or spread to the liver from elsewhere.
  • The tumor site is at least 1 centimeter beneath the liver surface and is distant from large vessels such as hepatic vein, portal vein more than 0.5 centimeters.
  • Downsize of liver cancer in order to facilitate subsequent surgery.
  • Combined with other procedures such as transarterial chemoembolization (TACE) in order to improve treatment efficacy.
  • Patients with blood coagulation problems.
  • The tumor is adjacent to vital organs such as the gallbladder, intestines, stomach, and heart.
  • The tumor size is more than 5 centimeters.
After you are discharged, it is recommended that you stay at a hotel close to the hospital for at least one day for convenience in traveling to the hospital if any complications arise after the procedure.
