In their series of 12 adult patients with a single painful osteolytic metastasis, Callstrom et al. (2002) showed onascale of 1 to 10,mean worst pain decreased from 8.4 to 3.1 after treatment. Osteoid osteomas are well suited to RF ablation because they are small, benign, and have finite growth. Approximately 90% of patients with osteoid osteoma are permanently cured after a single treatment. In such patients, percutaneous ablation with radiofrequency is essentially equivalent to operative excision (Rosenthal et al. 1998). 

Percutaneous ablation of bone metastasis with radiofrequency or laser can be used in the same indications as alcoholization. Radiofrequency and laser are able to... 

Cryotherapy and radiofrequency treatment can ablate metastases in 50%-90% of cases and are relatively safe compared to hepatic resection. With respect to overall survival, there has been no randomised comparison to show that either cryotherapy or radiofrequency treatment alter longterm survival compared with chemotherapy alone. However, this may be related to the fact that most patients being referred for ablation are considered unsuitable for hepatic resection. The ideal patient for ablative therapy would be one who, several years after a curative colonic resection for an early-stage well-differentiated cancer develops a small metastasis in the middle of a lobe of the liver (Primrose 2002). Such a patient is, however, also ideally suited to surgical treatment and for such a patient the longterm results of surgery are good. Interventional...
