Pulmonary neuroendocrine tumour-associated ectopic Cushing’s syndrome: diagnostic challenges and multidisciplinary management

Key Points

This research focuses on the challenges and management strategies for ectopic Cushing’s syndrome associated with pulmonary neuroendocrine tumors.
Identified cases of ectopic ACTH secretion leading to severe hypercortisolism.
Used a combined therapy approach involving metyrapone, ketoconazole, and hydrocortisone.
Employed 68Ga-DOTATOC PET-CT for localization and staging of neuroendocrine tumors.
Involved a multidisciplinary team for effective management.
Rapid cortisol control was achieved with combination therapy.
Early identification of complications led to better recovery outcomes.
Multidisciplinary management improved overall patient care and recovery.

Abstract

Ectopic ACTH secretion should be suspected in cases of severe, rapidly progressive hypercortisolism with marked hypokalaemia. Combined therapy with metyrapone and ketoconazole, along with hydrocortisone blockade and replacement, allows for rapid and safe cortisol control before surgery. 68Ga-DOTATOC PET-CT is essential for accurate localisation and staging of neuroendocrine tumours with ectopic ACTH production. Multidisciplinary management involving endocrinology, nuclear medicine, radiology, psychiatry, nutrition and thoracic surgery is crucial for successful outcomes. Early identification and aggressive management of metabolic and psychiatric complications are key to full recovery.
