Résumé
Background Percutaneous radiofrequency ablation (RFA) is effective in the management of bone tumors. However, knowledge of the complication rate and risk factors for complications of RFA is lacking. Purpose To report the complication rate and risk factors of bone tumor RFA. Materials and Methods This retrospective study reviewed complications in consecutive patients who underwent RFA of primary or metastatic bone tumors from January 2008 to April 2018. Complications were categorized into major (grade 3 or 4, severe or life-threatening) or minor (grade 1 or 2, mild or moderate) according to Common Terminology Criteria for Adverse Events. Univariable and multivariable regression analyses were performed to identify variables associated with complications of RFA. Results A total of 169 patients (median age, 63 years; interquartile range, 55-73 years; 85 men) with 217 tumors were evaluated. The total complication rate was 30.0% (65 of 217; 95% confidence interval [CI]: 23.8%, 36.0%). The major complication rate was 2.3% (five of 217; 95% CI: 0.8%, 5.3%), with secondary fracture being the most frequent event (1.8% [four of 217]). The minor complication rate was 27.7% (60 of 217; 95% CI: 21.7%, 33.6%), with immediate postoperative pain being the most frequent event (18.0% [39 of 217]). Risk factors for all complications included tumor size greater than 3 cm (adjusted odds ratio [AOR], 2.4 [95% CI: 1.2, 4.5]; = .03) and previous radiation therapy (AOR, 3.8 [95% CI: 2.0, 7.4]; = .02). The only risk factor for minor complications was previous radiation therapy (AOR, 2.2 [95% CI: 1.0, 4.7]; = .04). Conclusion Bone tumor radiofrequency ablation is safe, with a low rate of major complications mainly consistent with secondary fractures. Risk factors for complications are tumor size greater than 3 cm and previous radiation therapy. © RSNA, 2020
