is no consensus on the criteria for remission after resecting an ACTH-producing tumor.
is generally defined as;
serum cortisol values<5 mcg/dL (138 nmol/L) or UFC 28–56 nmol/d (10–20 g/d) within 7 days of selective tumor resection.
Although clinicians have used glucocorticoid dependence to characterize surgical response, we advocate measuring serum cortisol levels as a preferable and quantifiable alternative.
