Several interventional radiology procedures are available for the management of cancer pain. In this article, we will briefly review the different procedures and their value in the setting of cancer pain management under two main categories: indirect action (regional anesthesia from neurolysis) and direct action on the tumor. ⋯ Several indications have previously been validated, including thermal ablation of bone metastases with results superior to conventional therapies. Additional applications should be validated over the next few years.

Since the introduction of radiofrequency tumor ablation of liver tumors in the late 1990s, local destructive therapies have been applied to lung, renal and bone lesions. In addition, new techniques have been introduced to compensate for the limitations of radiofrequency ablation, namely the reduced rate of complete ablation for tumors larger than 3 cm and tumors near vessels larger than 3 mm. ⋯ While it is a technique based on thermal ablation similar to radiofrequency ablation, there are significant differences between both techniques. Electroporation, of interest because of the non-thermal nature of the ablation process, also is under evaluation.
