Radiofrequency ablation of lung tumours ­ new perspective in treatment of lung neoplasms

Abstract

Background. Percutaneous radiofrequency ablation (RFA) is a minimally invasive technique used to treat solid tumours. Because of its ability to produce large volume of coagulation necrosis in controlled fashion this technique has been progressively tested as a possible treatment of lung malignancies. Recent clinical studies have shown that RFA enables successful treatment of relatively small lung malignancies with high rate of complete response and acceptable morbidity and have suggested that the technique could represent a viable alternate or complementary method for patients with non-small cell lung cancer or lung metastases of favourable histotypes who are not candidates for surgical resection.

Conclusions. Initial intenational studies as well as the clinical experience of Institute of Radiology in Clinical Center Ljubljana, although limited, indicated that RFA is mostly well tolerated by patients and also, that it can result in complete necrosis of targeted lesion. Pneumothorax is most common procedure related complication, occurring in up to 40% of cases, with approx. half of them requiring drainage.
