[Percutaneous lung thermo-ablation].

Percutaneous lung thermo-ablation has steadily been developed over the past 15years. Main indications are early stage non-small cell lung carcinoma (NSCLC) for non-surgical patients and slow evolving localized metastatic disease, either spontaneous or following a general treatment. Radiofrequency, being the most evaluated technique, offers a local control rate of about 80-90% for tumors <3 cm in diameter. With excellent tolerance and very few complications, radiofrequency may be proposed for patients with a chronic disease. Other ablation techniques under investigation such as microwaves and cryotherapy could allow overcoming radiofrequency limits. Furthermore, stereotactic radiotherapy proposed for the same indications is efficient. Comparative studies are warranted to differentiate these techniques in terms of efficacy, tolerance and cost-effectiveness.
