Abstract

Introduction: In patients with history of cancer adrenal metastases can be found in up to 70% of adrenal tumors detected during follow-up. Currently, laparoscopic adrenalectomy (LA) is considered the gold standard approach for benign adrenal tumors but is still controversial in malignant disease. Depending on the patient's oncological status, adrenalectomy might be a possible treatment option. Our objective was to analyze the results of LA for adrenal metastasis from solid tumors in two referral centers.

Methods: Retrospective analysis of 17 patients with non-primary adrenal malignancy treated with LA between 2007 and 2019 was performed. Demographic and primary tumor data, type of metastasis, morbidity, disease recurrence and evolution were evaluated. Patients were compared according to type of metastases: synchronous (< 6 months) vs metachronous (≥ 6 months).

Results: 17 patients were included. Median metastatic adrenal tumor size was 4 cm (IQR, 3-5.4). We had one conversion to open surgery. Recurrence was found in 6 patients with one recurring in the adrenal bed. The median OS was 24 (IQR, 10.5-60.5) months and 5-year OS was 61.4% (95%CI: 36.7%-81.4%). Patients with metachronous metastases had better overall survival vs. patients with synchronous metastases (87% vs. 14%, p = 0.0037).

Conclusion: LA for adrenal metastases is a procedure associated with low morbidity and acceptable oncologic outcomes. Based on our results, seems reasonable to offer this procedure to carefully selected patients, mainly those with metachronous presentation. Indication of LA must be done on a case by case evaluation in the context of a multidisciplinary tumor board.
