Spinal metastases treated with bipolar radiofrequency ablation with increased (> 70 °C) target temperature: Pain management and local tumor control

To investigate the safety and clinical efficacy of bipolar radiofrequency ablation (b-RFA) with increased (> 70 °C) target temperature for treatment spine metastases intent achieving pain relief or local tumor control. Thirty-one patients a total 37 who were treated b-RFA vertebroplasty from January 2016 to May 2019 retrospectively included. There 20 women 11 men mean age 62.4 ± 10.5 (SD) years (range: 40–78 years). Patients characteristics, procedure details outcomes analyzed. Metastases predominantly located in lumbar (22/37; 59.5%) thoracic (13/37; 35.1%). Mean was 88.4 3.5 °C 70–90 °C). Technical success 100% (37/37 metastases). One (1/37; 2.7%) major complication unrelated reported. metastasis lost follow-up. Favorable outcome noted receiving management (16/20 metastases; 80%; follow-up, 3.4 2.9 [SD] months) oligometastatic/oligoprogressive disease (6/6 100%; 5.0 4.6 months). In prevent complications, favorable 6/10 (60%; 3.8 4.8 B-RFA has an excellent profile results high rates control disease. Suboptimal are achieved complications related growth index tumor.
