Also called Cushing Syndrome (pituitary-dependent), ACTH-secreting pituitary adenoma
Cushing Disease results from ACTH overproduction by a pituitary adenoma, stimulating excessive cortisol synthesis by the adrenal glands. Excess cortisol causes multiple systemic effects through glucocorticoid receptor activation.
Cushing Disease typically presents in adults aged 30-50 years, though it can occur at younger ages. It affects females more commonly than males, with a female-to-male ratio of approximately 3:1. The disease occurs across all racial and ethnic groups. The underlying ACTH-secreting pituitary adenoma is usually small (microadenoma) and may not be visualized on initial imaging.
Clinical trials for Cushing Disease focus on optimized surgical techniques, radiation therapy protocols, and novel medical therapies for disease control when surgery or radiation fails. Pasireotide, cabergoline, and ketoconazole represent medical options being refined in trials. Novel agents targeting ACTH secretion or cortisol synthesis are under investigation. Transsphenoidal surgery remains the primary treatment, with refined techniques improving success rates. Patients should consult with an endocrinologist and neurosurgeon experienced in Cushing disease.
