[Minimally invasive techniques for treatment of metastatic cancer].

Many percutaneous image-guided ablative techniques have been used in the treatment of cancer-related bone metastases. These techniques are rapidly becoming a focus in the palliative and curative treatment of patients with both benign and malignant bone cancer.In this article we will briefly review the principles of radiofrequency ablation and our experience with this technique, including its use in combination with surgery; we will also discuss other minimally invasive techniques such as cryoablation and osteoplasty in the treatment of bone metastases.
