Nearly half of adults with Cushing’s disease that persists or recurs after surgical treatment require second and sometimes third therapeutic interventions, including pituitary surgical reintervention, radiotherapy, pharmacotherapy or bilateral adrenalectomy, study data from Mexico show. Moisés Mercado, MD, FRCPC, of the ABC Hospital Neurological and Cancer Centers in Mexico City, and colleagues evaluated 84 adults (median age, 34 years; 77 women) with Cushing’s disease to determine the long-term efficacy of secondary interventions for persistent and recurrent Cushing’s disease. Median follow-up was 6.3 years. Overall, 81 participants were primarily treated with transsphenoidal surgery. More than half experienced long-lasting remission (61.7%); disease remained active in 16%, who were diagnosed with persistent Cushing’s disease; and 22% experienced relapse after remission and were diagnosed with recurrent Cushing’s disease. After the initial procedure, 18 participants required pituitary surgical reintervention, including 10 with recurrent and eight with persistent disease. Radiation therapy was administered to 14 participants, including two as primary therapy and 12 after failed pituitary surgery. Pharmacologic treatment with ketoconazole was prescribed for 15 participants at one point during the course of disease. Bilateral adrenalectomy was performed in 12 participants. Pituitary surgical reintervention was the most commonly used secondary treatment (22.2%), followed by pharmacologic therapy with ketoconazole (16%), radiotherapy (14.8%) and bilateral adrenalectomy (14.8%). More than half of participants experienced early remissions after a second operation (66.6%) and radiotherapy (58.3%), whereas long-lasting remission was reached in only 33.3% of participants who underwent a second surgery and 41.6% of participants who underwent radiotherapy. Half of participants who underwent bilateral adrenalectomy were diagnosed with Nelson’s syndrome. Overall, 88% of participants achieved remission, and disease was biochemically controlled with pharmacologic treatment in 9.5% of participants after their initial, secondary and third-line treatments. “The efficacy of treatment alternatives for recurrent or persistent [Cushing’s disease] vary among patients, and often, more than one of these interventions is required in order to achieve a long-lasting remission,” the researchers wrote. – by Amber Cox Disclosure: The researchers report no relevant financial disclosures.
