Radio-Frequency Ablation

Liver Metastases

ABSTRACT: Radio-Frequency Ablation Of Liver Metastases Secondary     To Breast Cancer Promising     [09/17/2001; Doctor's Guide]

Radio-frequency ablation is a safe, simple and effective method of removing liver metastases secondary to breast cancer in comparison with surgery.

Between 5 and 12 percent of patients with primary breast cancer have liver metastases and survival rates improve once the secondary liver tumours are resected.

Dr Tito Livraghi and colleagues from The Department of Radiology at the Ospedale Civile in Vimerveate, Italy, undertook evaluation of 24 patients who had undergone resection of breast cancer.

Sixty-seven percent of the patients underwent treatment for a simple liver lesion whilst 33 percent had multiple lesions. Eighty-seven percent of the patients received general anaesthetic. The remainder, whose lesions were less than three centimetres, received sedation and analgesia before insertion of one or two electrodes within the liver lesion. Under ultrasound guidance, a device attached to the transducer was used to position the electrode within the lesion.

Consequently, treatment was limited to the lesions which were sonographically visible and, as radio-frequency energy was applied, a hyperechoic focus replaced the tumour.
