ObjectiveWe report the safety and efficacy of combined radiofrequency ablation and cementoplasty in treating painful neoplastic bone lesions.Materials And MethodsFifty-three combined radiofrequency ablation and cementoplasty procedures were completed in 36 patients. Thirty-four vertebrae (20 lumbar, 14 thoracic), 14 acetabulae, 3 sacra, 1 pubic symphysis, and 1 humerus were treated. Patient age ranged from 34 to 81 years (mean 57.6 years, SD=12.6). Primary malignancies included: 12 breast, 5 lung, 6 multiple myeloma, 2 prostate, 2 renal cell carcinoma, 1 synovial sarcoma, 1 endometrial, 1 oral squamous cell carcinoma, 1 lymphoma, 1 colon, 1 transitional cell carcinoma, 1 colorectal, 1 cholangiocarcinoma, and 1 pheochromocytoma. Primary neoplasm location, pain levels pre- and post-procedure (as assessed using the Visual Analog Scale), number of radiofrequency (RF) treatments and any extravasation were documented.ResultsCombined radiofrequency ablation (RFA) and cementoplasty procedures were performed with 100% technical success (53 out of 53). The mean pre-procedure and post-procedure pain, as measured by the Visual Analog Scale (VAS), was 7.2/10 and 3.4/10 respectively. Symptomatic complications included one case of self-resolving transient thermal sciatic neurapraxia following RFA and acetabuloplasty. Two cases of transient pain following epidural leaks during treatment of thoracic vertebrae and breast metastases also occurred. Non-symptomatic complications, from a variety of cases, included cement emboli to the lung, incidental, non-symptomatic leaks into the needle track, spinal canal, draining veins, disc spaces, and an intra-articular leak into the hip joint.ConclusionCombined RFA and cementoplasty appears to be safe, practical and effective in the palliative treatment of painful neoplastic lesions.
