- Purpose: The present study evaluates the usefulness of an ACTH suppression test shortly after surgery, and to determine optimal cut-off values of included laboratory analyses, in predicting short- and long-term remission after surgery of Cushing’s disease. Methods: A 48 h suppression test with betamethasone 2 mg/day applied after 45 transphenoidal adenomectomies in 28 patients was evaluated. Receiver operating characteristic (ROC)-curves were created for the included assays: plasma cortisol, plasma adrenocorticotropic hormone (ACTH) and urinary free cortisol (UFC). Plasma levels of cortisol and ACTH were measured both at 24 and 48 h. Youden’s index was used to determine cut-off with the highest sensitivity and specificity in predicting short- (3 months) and long-term (5 years or longer) remission. The area under curve (AUC) illustrated the clinical accuracy of the different assays. Results: Plasma cortisol after 24 h with betamethasone was most accurate in predicting both short- and long-term remission. 3 months remission with cut-off 107 nmol/L: sensitivity 0.85, specificity 0.94, positive predictive value (PPV) 0.96 and AUC 0.92 (95% CI 0.85–1). 5 years remission with cut-off 49 nmol/L: sensitivity: 0.94, specificity 0.93, PPV 0.88, AUC 0.98 (95% CI 0.95–1). Analyses of ACTH or UFC did not improve diagnostic accuracy. Conclusions: A 48 h, 2 mg/day betamethasone suppression test after transphenoidal surgery of Cushing’s disease could predict short- and long-term remission with a high accuracy. Suppression of plasma cortisol after 24 h with betamethasone to values excluding Cushings disease in the diagnostic setting yielded the highest accuracy in predicting long-term remission.

- Objective Endoscopic pituitary surgery has shown favorable clinical outcomes. Less is known about the impact of surgical approaches on health-related quality of life (HRQoL) and work capacity. The present study was undertaken to compare transsphenoidal microscope-assisted surgery with endoscopic transsphenoidal surgery regarding preoperative and surgical factors for the final outcome of HRQoL and work capacity. Methods In a retrospective study of patients operated on for pituitary adenoma, outcome was compared between those operated on before and after transition with endoscopic surgery at our department. Data were gathered via patient questionnaires and patients' files. Results After exclusions, 235 patients were included (99 microsurgical and 136 endoscopic). Frequency of complications was similar but tumor size was significantly larger in the endoscopic group. Complications did not affect HRQoL or work capacity. HRQoL was not affected by surgical technique but showed an overall trend toward lower values compared with the general population. Sick leave, return to work frequency, and permanent sick leave were not affected by surgical technique. Female gender was a factor for lower ratings in all outcome variables. Conclusions Surgical technique does not influence HRQoL or work capacity in this long-term follow-up although both are decreased compared with the general population. We conclude that fully endoscopic pituitary surgery, despite including larger tumors, bears the same risk for complications as microsurgery. In addition, females have a greater risk for decrease in HRQoL and work ability. This factor should be taken into account when informing patients and appreciating expectations of treatment.
