Research Question & Objectives~To conduct a prospective, single-centre study of combined ablation and cementoplasty treatment for painful spinal and extraspinal osseous lesions.~Report the technical outcome and safety of percutaneous ablation prior to image-guided cementoplasty in a single treatment session.~Review the effectiveness and durability of pain control, local tumor control, and the impact on QoL using ablation and cementoplasty in treating spinal/extraspinal osseous tumors.~Assess the feasibility and efficacy of ablation and cementoplasty treatment for different primary tumor types and benign lesions.~Research Design~The investigators will conduct a single-centre, single-arm, cohort analysis of all patients who undergo cementoplasty for osseous disease in the department of interventional radiology over a two-year period. This will be a prospective paired comparison study with patients serving as their own controls. Technical success and procedural complications will be monitored and recorded for all patients. All patients will be followed until death or 3 months post-procedure.~The investigators aim to enroll a minimum of 40 patients referred for symptomatic osseous lesions. Bipolar radiofrequency ablation (Osteocool RFA system, Medtronic) or cryoablation (Visual Ice Cryoablation, Boston Scientific) will be performed under CT, ultrasound, or fluoroscopic guidance at the discretion of the treating radiologist, and immediately followed by cement injection. Radiological outcomes, including local tumor control and disease progression, will be assessed by CT imaging immediately post-procedure as well as 3-month follow-up. Clinical outcomes will be evaluated by VAS, analgesic use, and QoL assessment using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) prior to procedure and immediately post-procedure, as well at 1-week, 1-month, and 3-month intervals post-procedure.
The aim of this research study is to assess the effectiveness of combined ablation and cementoplasty in the treatment of spinal, pelvic, and extraspinal lesions causing pain resistant to conventional treatment at our centre. In particular, the investigator seek to verify the safety and efficacy for multiple primary tumor types and benign lesions as well as encompass multiple measurements of outcome, including visual analog scale (VAS) for pain, opioid and analgesic use, and overall performance scales, combined with cross-sectional imaging follow-up to assess tumor burden, to ascertain a comprehensive Canadian single-centre experience that has been lacking in previous studies.
