Application of radionics on primary and metastatic tumours of the liver.

The aim of our study is to present our initial experience on the use of radiofrequency ablation (RFA) on hepatic tumours. Four patients with tumours of the liver were submitted to RFA. The first patient underwent an emergency left lobectomy due to rupture of a tumour of the left hepatic lobe. A synchronous tumour was detected on the right lobe. He has been submitted to four sessions of RFA. The second patient was submitted to transverse colon resection (adenocarcinoma) and a year later three metastatic tumours were detected. Two sessions of RFA have been applied in this case. The third patient, with adenocarcinoma of the sigmoid and one metastatic lesion on the right hepatic lobe, and the fourth patient with breast cancer and metastatic lesion of the liver, underwent one session of RFA each. The use of RFA on metastatic or primary tumours of the liver enriches the possibilities of therapeutic treatment.
