Resection of adrenal metastases from non-small cell lung cancer: a multicenter study.
BACKGROUND
In recent case reports and limited series, adrenalectomy was recommended for an isolated adrenal metastasis from non-small cell lung cancer (NSCLC).


METHODS
We retrospectively studied patients with a solitary adrenal metastasis from NSCLC who had undergone potentially curative resection in eight centers.


RESULTS
Forty-three patients were included. Their adrenal gland metastasis was discovered synchronously with NSCLC in 32 patients, and metachronously in 11. It was homolateral to the NSCLC in 31 patients and contralateral in 12 (p < 0.01). Median survival was 11 months, and 3 patients survived more than 5 years. There was no difference between the synchronous and metachronous groups regarding recurrence rate or survival. Survival was not affected by the homolateral location of the metastasis, the histology of the NSCLC, TNM stage, any adjuvant and neoadjuvant treatment, or, in the metachronous group, a disease-free interval exceeding 6 months.


CONCLUSIONS
We confirm the possibility of long-term survival after resection of isolated adrenal metastasis from NSCLC, but no clinical or pathologic criteria were detected to identify patients amenable to potential cure.
