Combined Complementary Local Therapies for Pain Palliation and Local Control of a Pelvic Osteosarcoma

Radiation therapy (RT) has been the gold standard for the nonsurgical treatment and palliation of metastatic bone lesions.1 In the past decade, minimally invasive, percutaneous image guided ablation (eg, radiofrequency, microwave, and cryoablation) has also become part of the multidisciplinary treatment algorithm and is included in many of the histology treatment recommendations in the National Comprehensive Cancer Network guidelines. As used in this case, cryoablation would be the choice of thermal ablation because it allows visualization of the ablation zone on computed tomography and the ability to sculpt and create large ablation zones with multiple percutaneously placed cryoprobes, especially for bone lesions with soft tissue extension.
