To evaluate local control and survival after image-guided ablation of adrenal gland metastases.

Image-guided ablations of adrenal metastases measuring < 5 cm performed at 2 academic medical centers between July 2002 and June 2016 were analyzed. There were 51 procedures performed on 46 tumors (mean diameter 2.8 cm ± 1.1; range, 0.7–4.9 cm) in 38 patients (mean age 66 y; range, 41–80 y) with renal cell carcinoma (n = 17 patients; 45%), non–small cell lung cancer (n = 10 patients; 26%), and other primary malignancies (n = 11 patients; 29%). Treatment modalities included cryoablation (n = 30 procedures; 59%), radiofrequency ablation (n = 12 procedures; 24%) and microwave ablation (n = 9 procedures; 18%). Technical success, primary and secondary efficacy, local progression rate, local progression-free survival, and overall survival were assessed. Mean follow-up …
