Determinants for malignancy in surgically treated adrenal lesions.

Forskningsoutput: TidskriftsbidragArtikel i vetenskaplig tidskrift


PURPOSE: It is difficult to definitively rule out or establish malignancy pre-operatively in patients with adrenal lesions referred for adrenal surgery. The aim of this study was to identify risk factors for a malignant diagnosis in patients treated with adrenalectomy. METHODS: Consecutive adrenalectomies at the Department of Surgery, Lund University Hospital between 2000 and 2009 were identified. Pre-operative clinical, radiological and biochemical data, as well as details on the operation and histology, were retrieved from patients' medical records. RESULTS: There were 175 adrenal operations in 172 patients (98 female and 77 male). There were 28 malignancies. Malignant tumours were larger than in benign cases (p = 0.003), had radiological signs of malignancy more often (p = 0.001) and the patients were more likely to have a history of malignancy (p = 0.001). There were no differences regarding age, gender, body mass index or mode of detection (incidental vs. clinical) between patients with benign and malignant diagnoses. A unilateral uptake on fluorine-18 deoxyglucose positron emission tomography was more frequent in malignant cases than in benign; however, this association did not reach statistical significance. CONCLUSIONS: Size of adrenal lesion, suspicious radiological findings and history of malignancy were factors associated with malignancy.
