[Percutaneous ablation of metastases: where are we and new techniques]

When a metastatic disease is localized and slowly evolving either spontaneously or after a general treatment, a local treatment may be proposed. For about 15 years, image-guided percutaneous ablation has been developed which allows to treat tumors with temperature modifications. These mini-invasive techniques may be repeated in patients whose disease may be chronic. Ablation techniques are also used in a more palliative manner on bone metastases to obtain pain relief.
