BACKGROUND: Management of Cushing’s disease (CD) is complex, particularly in the setting of recurrent or persistent disease.
OBJECTIVE: To develop consensus statements on the management of patients with persistent or recurrent CD.
METHODS: The study used the RAND/UCLA modified Delphi process. A panel of 11 expert endocrinologists from diverse US locations and several practice types rated 708 unique patient scenarios twice: once on their own and once following a day-long, professionally moderated, panel discussion to clarify definitions. For each scenario (e.g., a hypopituitary patient with severe hypercortisolism without fulminant CD and a macroadenoma), panelists rated appropriateness for different treatment options on a 1-9 scale as the first intervention after it was determined that the patient had residual or recurrent tumor. Responses were grouped as appropriate (median rating of 7-9 with no disagreement between panelists), least desirable (median rating of 1-3 with no disagreement), or uncertain (median rating of 4-6 with no disagreement). Scenarios with >2 ratings from 1-3 and >2 from 7-9 range were considered to have disagreements between panelists.
RESULTS: Panelists had practiced medicine a median of 29 years, and spent about 50% of their time in clinical care and 25% conducting research; panelists reported seeing on average about 30 unique CD patients per year. The majority were from academic/tertiary settings. Agreement about which treatment would be ideal vs. undesirable for individual treatment scenarios increased following the panel discussion from 82.1% (581 scenarios) to 97.5% (690) in the final ratings, with 43.4% of the treatment options in specific scenarios rated appropriate, 21.6% rated uncertain, and 32.5% rated least desirable. Consensus statements were developed based on the final ratings with input from the panel. These include: 1) If residual tumor is identified, and an expert pituitary surgeon believes it is operable, repeat pituitary surgery can be considered; 2) Medical therapy can be used as initial treatment of nearly all cases of recurrent or persistent CD; 3) Radiotherapy can be used as an initial treatment option in recurrent or persistent CD when combined with medical therapy.
CONCLUSIONS: Using the RAND/UCLA modified Delphi method, a panel of expert endocrinologists developed consensus recommendations for recurrent or persistent CD. The panel emphasized that the optimal treatment approach involves shared decision-making with the patient, endocrinologist, and neurosurgeon, and requires weighing multiple factors, including patient preferences; size, location and characteristics of residual tumor; concurrent medication use; drug interactions; cost; and the availability of expert care.
