Pitfalls in the management of Cushing's disease

WOS: 000246346900001PubMed: 17386367Cushing's disease is caused by functional corticotroph adenomas of the pituitary gland, most commonly noninvasive microadenomas. Transsphenoidal microsurgery is an effective means of control for patients with adrenocorticotrophic hormone-producing microadenomas. However, a wide variation of clinical outcomes and recurrence rates has been reported. The major causes of surgical failure in the treatment of Cushing's disease lies in inadequate preoperative evaluation, unsuccessful identification of the adenoma and inexperience of the surgeon. Furthermore, appropriate use of combination therapy, including surgery, radiotherapy, radiosurgery and adrenalectomy can improve the outcome. For optimal results in this rare disease, endocrinological, radiological and surgical procedures should be co-ordinated in a specialized center. In this review, factors affecting preoperative evaluation, surgical success and outcome are outlined in the light of current knowledge. (C) 2006 Elsevier Ltd. All rights reserved
