Overview and Indications
Painful bone tumors, particularly metastases, are common among cancer patients and are a major cause of impaired mobility, deficient functional independence and overall diminished quality of life.
Minimally invasive percutaneous bone thermal ablation procedures are performed in selected patients with bone metastases, such as patients who have not adequately responded to or have contraindication to radiation therapy, patients for whom surgery is not an option and patients who have not responded to medical therapies, to achieve pain relief and/or local tumor control following multidisciplinary discussions with medical oncologists, surgical oncologists and radiation oncologists. These procedures use either heat (radiofrequency and microwave ablation) or cold (cryoablation) to destroy tumor cells. Minimally invasive bone thermal ablation is typically an outpatient procedure and requires short recovery. A radiologist places thin ablation needles into the tumor from the skin surface using imaging guidance. Subsequently, heat or cold is applied, through the ablation needles, to treat the tumor.
