Steroid metabolomics in adrenocortical carcinoma reveals mitotane as an inducer of CYP3A4 and an inhibitor of 5alpha-reductase activity with major implications for drug metabolism and hydrocortisone replacement

Mitotane (o,p’DDD) is the first-line treatment for metastatic adrenocortical carcinoma (ACC) and is also regularly used in the adjuvant setting after presumed complete removal of the primary tumour. Mitotane is considered an adrenolytic substance, but no information is available regarding distinct steroidogenic effects. Here we carried out steroid metabolomics by gas chromatography/mass spectrometry in 24-hour urine samples from 106 patients with ACC and with samples coll...

Adrenal tumors have an incidence of 2–3% in the general population and the work-up of incidentally discovered adrenal masses represents a major burden to the health system. Differentiating adrenocortical adenoma (ACA) from adrenocortical carcinoma (ACC) represents a continuous challenge, with unfavorable sensitivities and specificities provided by tumor size, imaging and even histology. Here, we aimed to develop a reliable screening tool for the detection of adrenal malig...
