Purpose

To demonstrate an approach where patients with lytic spinal metastases or multiple myeloma lesions in the spine can be treated by both conventional therapy and radiofrequency ablation in order to dramatically improve their quality of life.

Methods & Materials

Multiple patients with lytic metastases and/or multiple myeloma which were treated with radiofrequency ablation after treatment with chemotherapy and/or radiation therapy. These patients had uncontrollable pain (10/10), were poor surgical candidates, and/or were status-post maximum radiation dose. These patients then underwent RFA under CT guidance.

Results

Over the span of 2 years we had 90.4% response rate with a low (9.5) rate of complications. Many patients had a decrease in pain of (2/10) while others were able to discontinue the use of opiates.

Conclusion

Radiofrequency Ablation for the treatment of spinal metastases can dramatically improve a patient's quality of life in many cases where traditional treatments like chemotherapy and radiation therapy have failed.
RFA is a promising new technique in the fight against bone cancer pain. It provides great relief of pain in bone tumors with a 90% response rate. RFA complication rates are low and the procedure is well tolerated.
RFA adds another dimension in the treatment of osteolytic mets and myeloma.
RFA can be applied in conjunction to PMMA injection to treat pain and stabilize bones.
Taking advantage of the strengths of RFA , chemo and XRT may lead to combined approaches, producing a synergistic effect and improved response and survival.
