Introduction
While cryoablation (CA) and microwave ablation (MWA) have both been implemented as approaches to the treatment of adrenal metastasis (AM), the outcomes associated with these two therapeutic strategies remain unclear.

Aim
To compare the safety and efficacy of CA and MWA as treatments for AM in patients with non-small-cell lung cancer (NSCLC).

Material and methods
Consecutive patients with AM secondary to NSCLC from January 2015 to December 2020 underwent CA or MWA. Treatment-related outcomes and complications were retrospectively compared between these groups.

Results
In total, 68 NSCLC patients with isolated AM were enrolled in this study, of whom 35 and 33 underwent treatment with CA and MWA, respectively. Primary complete ablation rates in the CA and MWA groups were 91.4% (32/35) and 93.9% (31/33) respectively (p = 1.000), while a 100% secondary complete ablation rate was observed for both groups. Hypertensive crisis incidence affected 11.4% (4/35) and 9.1% (3/33) of patients in the CA and MWA groups (p = 1.000), respectively, while 8 (22.9%) and 8 (24.2%) patients in these corresponding groups experienced local progression after ablation that was detected during the follow-up period (p = 0.893). Patients in the CA and MWA groups exhibited a median progression-free survival of 18 and 22 months, respectively (p = 0.411), while the corresponding median overall survival of patients in these groups was 25 and 29 months (p = 0.786).

Conclusions
CT-guided CA and MWA appear to exhibit similar safety and efficacy profiles when employed to treat isolated AM in NSCLC patients.
