ABSTRACT

Objective To investigate the effects of percutaneous radio frequency ablation of liver cancer, and evaluate the indications, contraindications, and side effects. Methods One hundred and fifty four patients with hepatocellular carcinoma or metastases liver cancer, with the average diameter of the tumours 7.07 cm were treated with by radio frequency RF 2000TM instrument, the results were evaluated. Results Average theraputic time was 1.18 times, the theraputic point was 5.74. The symptoms were improved after therapy, and the average concentration of AFP was droped from 1 553.68 ng/ml to 883.70 ng/ml. The percentage of tumour reduction was 56.8%. There were no serious complications observed. Conclusion Percutaneous radio frequency ablation of liver cancer is a simple, safe and effective method. For larger liver cancer several times action will be needed, or other intervantion therapy is added to enhance effectiveness.
