ObjectiveTo provide a nationwide description of postoperative outcomes and analysis of prognostic factors following adrenalectomy for metastases.BackgroundAdrenal glands are a common site of metastases in many malignancies. Diagnosis of adrenal metastases is on the rise, leading to an increasing number of patient candidates for surgery without consensual management.MethodsWe conducted a population-based study between January 2012 and December 2022 using the French National Health Data System (SNDS) and the Eurocrine registry (NCT03410394). The first database exhaustively covers all procedures carried out in France, while the second provides more clinical information on procedures and tumor characteristics, based on the experience of 11 specialized centers.ResultsFrom the SNDS, we extracted 2515 patients who underwent adrenalectomy for secondary malignancy and 307 from the Eurocrine database. The most common primary malignancies were lung cancer (n=1203, 47.8%) and renal cancer (n=555, 22.1%). One-year survival was 84.3% (n=2120). Thirty-day mortality and morbidity rates were, respectively, 1.3% (n=32) and 29.9% (n=753, including planned intensive care unit - stays). Radiotherapy within the year before adrenalectomy was significantly associated with higher 30-day major complication rates ( P =0.039). In the Eurocrine database, the proportion of laparoscopic procedures reached 85.3% without impairing resection completeness (R0: 92.9%). Factors associated with poor overall survival were the presence of extra-adrenal metastases (hazard ratio =0.64; P =0.031) and incomplete resection (≥R1; hazard ratio=0.41; P =0.015).ConclusionsThe number of patients who can receive local treatment for adrenal metastases is rising, and adrenalectomy is more often minimally invasive and has a low morbidity rate. Subsequent research should evaluate which patients would benefit from adrenal surgery.Copyright © 2024 Wolters Kluwer Health, Inc. All rights reserved.
