The purpose of this study was to analyze our experience with surgically treated isolated adrenal metastases in order to find those factors which can significantly affect survival. This method includes a retrospective single-center chart review. We evaluated how overall survival and disease-free survival (DFS) were influenced by demographic, tumor, and procedure-related variables. Thirty-seven adrenalectomies were performed in 34 patients. Procedures included 25 laparoscopic and 12 open adrenalectomies. Median follow-up was 49 months. Median overall survival was 63 months. Patients submitted to laparoscopic approach had a median survival of 57 months while it was 65 months for those who underwent open procedure (p = 0.67). DFS was 30 months, and these were 35 and 25 months after laparoscopic approach and open approach, respectively (p = 0.59). The concurrent resection of the adrenal metastasis with the primary tumor was the only factor influencing DFS (HR 6.8 95 % CI 1.2-37.3, p = 0.02). Patients with non-small cell lung cancer (n = 15) had a median survival of 63 months and DFS of 35 months. Our experience confirms that adrenalectomy, regardless of the surgical approach, can offer durable disease-free and overall survival outcomes for surgical candidates with isolated adrenal metastases.
