Long term results of transsphenoidal adenomectomy in patients with Cushing's disease.

| Abstract |
As part of an ongoing series, 100 patients with Cushing's disease underwent transsphenoidal operations. Pituitary adenomas were confirmed in 93 patients, and initial remission was achieved in 86 (92%) of them. Hypercortisolemia was not corrected in 7 patients, and in 4 this was due to invasive adenomas. These patients were subjected to irradiation, medical treatment, or both after operation. Only 7 of the 100 patients had no pituitary adenoma found at operation, and they obtained no clinical remission even after partial or subtotal hypophysectomy. Follow-up review, with an emphasis on endocrinological studies, was performed on these patients for a mean period of 38 months. Seventy-eight patients were in long term remission after operation and had restoration of noncorticotropic hormone secretion as well as pituitary-adrenal function. Recurrence was noted in 8 patients after 19 to 82 months in remission. In all of these patients, pituitary adenomas were verified by reoperation and no case of corticotrophic cell hyperplasia was noted. We conclude that late recurrence of Cushing's disease may occur after adenoma removal and is due to the regrowth of adenoma cells left behind in the peritumoral tissue at the first operation. In view of the overall remission rate, transsphenoidal adenomectomy is considered a highly effective treatment for Cushing's disease.
