<unk> , generally, carries a poor prognosis, with an overall 5-year survival rate of about 50%. Five-year disease-free survival for a complete resection of a stage I–III<unk>  is about 30%. The most important prognostic factors are age of the patient and stage of the tumor. Poor prognostic factors include mitotic activity, venous invasion, weight of 50 g or more, diameter of 6.5 cm or more, Ki-67/MIB1 labeling index of 4% or more, and p53 positive. In its malignancy,<unk>  is unlike most tumours of the adrenal cortex, which are benign (adenomas) and only occasionally cause Cushing's syndrome.
