Irina Bancos, M.D., an endocrinologist at Mayo Clinic in Rochester, Minnesota, and Jamie J. Van Gompel, M.D., a neurosurgeon at Mayo Clinic’s campus in Minnesota, discuss Mayo’s multidisciplinary approach to adrenocorticotropic hormone (ACTH)-secreting pituitary tumors. Pituitary tumors are common and often don’t cause problems. But some pituitary tumors produce the hormone ACTH, which stimulates the production of another hormone (cortisol). Overproduction of cortisol can result in Cushing syndrome, with signs and symptoms such as weight gain, skin changes and fatigue. Cushing syndrome is rare but can cause significant long-term health problems.
Treatment for Cushing syndrome caused by a pituitary tumor generally involves surgery to remove the tumor. Radiation therapy and occasionally adrenal surgery may be needed to treat Cushing syndrome caused by ACTH-secreting pituitary tumors. Mayo Clinic has experience with this rare condition.
