Lack of response to octreotide in Cushings syndrome due to metastatic adrenocortical carcinoma

摘要

Functional metastatic adrenocortical carcinoma is an uncommon cause of Cushing's syndrome, which rarely responds to conventional treatment. A patient presenting with Cushing's syndrome secondary to adrenocortical carcinoma underwent surgical resection. Post-operatively, she developed metastatic disease resistant to conventional chemotherapy. Octreotide, a somatostatin analogue which is effective in the treatment of several types of neuroendocrine tumour, was tried to ameliorate her secretory symptoms, but without any therapeutic effect.
