We review the clinical and biochemical criteria used for evaluation of the transsphenoidal pituitary surgery results in the treatment of Cushing's disease (CD). Firstly, we discuss the pathophysiology of the hypothalamic-pituitary-adrenal axis in normal subjects and patients with CD. Considering the series published in the last 25 years, we observed a significant variation in the remission or cure criteria, including the choice of biochemical tests, timing, threshold values to define remission, and the interference of glucocorticoid replacement or previous treatment. In this context we emphasize serum cortisol levels obtained early (from hours to 12 days) in the postoperative period without any glucocorticoid replacement or treatment. Our experience demonstrates that: (i) early cortisol < 5 to 7 µg/dl, (ii) a period of glucocorticoid dependence > 6 mo, (iii) absence of response of cortisol/ACTH to CRH or DDAVP, (iv) return of dexamethasone suppression, and circadian rhythm of cortisol are appropriate indices of remission of CD. In patients with undetectable cortisol levels early after surgery, recurrence seems to be low. Finally, although certain biochemical patterns are more suggestive of remission or surgical failure, none has been proven to be completely accurate, with recurrence observed in approximately 10 to 15% of the patients in long-term follow-up. We recommended that patients with CD should have long-term monitoring of the CRH-ACTH-cortisol axis and associated co-morbidities, especially hypopituitarism, diabetes mellitus, hypertension, cardiovascular disturbances, and osteoporosis.

Abstract Introduction The clinical practice and research in the diagnosis and management of Cushing’s disease remains heterogeneous and challenging to this day. We sought to establish the characteristics of Cushing’s disease, and the trends in diagnosis, management and reporting in this field. Methods Searches of PubMed and Embase were conducted. Study protocol was registered a-priori. Random-effects analyses were conducted to establish numerical estimates. Results Our screening returned 159 papers. The average age of adult patients with Cushing’s disease was 39.3, and 13.6 for children. The male:female ratio was 1:3. 8% of patients had undergone previous transsphenoidal resection. The ratio of macroadenomas: microadenomas:imaging-undetectable adenomas was 18:53:29. The most commonly reported preoperative biochemical investigations were serum cortisol (average 26.4µg/dL) and ACTH (77.5pg/dL). Postoperative cortisol was most frequently used to define remission (74.8%), most commonly with threshold of 5µg/dL (44.8%). Average remission rates were 77.8% with recurrence rate of 13.9%. Median follow-up was 38 months. Majority of papers reported age (81.9%) and sex (79.4%). Only 56.6% reported whether their patients had previous pituitary surgery. 45.3% reported whether their adenomas were macroadenoma, microadenoma or undetectable. Only 24.1% reported preoperative cortisol, and this did not improve over time. 60.4% reported numerical thresholds for cortisol in defining remission, and this improved significantly over time (p = 0.004). Visual inspection of bubbleplots showed increasing preference for threshold of 5µg/dL. 70.4% reported the length of follow up. Conclusion We quantified the characteristics of Cushing’s disease, and analysed the trends in investigation and reporting. This review may help to inform future efforts in forming guidelines for research and clinical practice.

Stepwise Approach

Cushing’s Disease is caused by oversecretion of ACTH from a pituitary adenoma and results in subsequent elevations of systemic cortisol, ultimately contributing to reduced patient survival. The diagnosis of Cushing’s Disease frequently involves a stepwise approach including clinical, laboratory, neuroimaging, and sometimes interventional radiology techniques, often mandating multidisciplinary collaboration from numerous specialty practitioners. Pituitary microadenomas that do not appear on designated pituitary MRI or dynamic contrast protocols may pose a particularly challenging subset of this disease. The treatment of Cushing’s Disease typically involves transsphenoidal surgical resection of the pituitary adenoma as a first-line option, yet may require the addition of adjunctive measures such as stereotactic radiosurgery or medical management to achieve normalization of serum cortisol levels. Vigilant long-term serial endocrine monitoring of patients is imperative in order to detect any recurrence that may occur, even years following initial remission. In this paper, a stepwise approach to the diagnosis, and various management strategies and associated outcomes in patients with Cushing’s Disease are discussed.

Background: The relationship between circulating ACTH levels and cortisol secretion in Cushing's disease is not precisely known. Hypothesis: Chronic ACTH hyperstimulation leads to decreased adrenal potency and is restored after normalization of ACTH secretion. Subjects: Subjects included 20 patients with Cushing's disease, eight patients in long-term remission, and 36 healthy controls. Outcomes: ACTH and cortisol secretion rates and analytical dose-response estimates of endogenous ACTH efficacy (maximal cortisol secretion), dynamic ACTH potency, and adrenal sensitivity (slope term) from 24-h ACTH-cortisol profiles were evaluated. Results: Both basal and pulsatile secretion of ACTH and cortisol were increased in patients with active disease but normal in cured patients. ACTH, but not cortisol pulse frequency, was amplified in patients and restored after successful surgical treatment. ACTH EC50, an inverse measure of potency, was higher during pulse onset in Cushing's disease (59 ± 7.4 ng/liter) than in controls (20 ± 3.7 ng/liter) (P &lt; 0.0001) and remitted patients after surgery [15 ± 3.2 ng/liter, P value not significant (NS) vs. controls] and during pulse recovery phases [128 ± 18 (P &lt;0.0001), 70 ± 8.4, and 67 ± 17 ng/liter (NS vs. controls), respectively]. Efficacy was increased in active disease and normalized after surgical treatment [patients, 38 ± 8.3 nmol/liter · min, vs. controls, 21 ± 2.3 nmol/liter · min (P &lt;0.0001), and cured patients, 15 ± 3.2 nmol/liter · min (NS vs. controls)]. Sensitivity to endogenous ACTH did not differ among the three groups. Conclusion: The adrenal gland in Cushing's disease exhibits decreased responsiveness to submaximal ACTH drive and amplified efficacy, with unchanged sensitivity. These target-gland abnormalities are reversible in long-term remission after pituitary surgery.

OBJECTIVE: The aim of this study was to review the results of surgery for pediatric patients with Cushing's disease who were less than 18 years old and underwent transsphenoidal surgery in a specialized center during a 25-year period. SUBJECTS AND METHODS: Retrospective study, in which the medical records, histology and pituitary imaging of 15 consecutive pediatric patients with Cushing's disease (mean age: 13 years) were evaluated by the same team of endocrinologists and a neurosurgeon from 1982 to 2006. Patients were considered cured when there was clinical adrenal insufficiency and serum cortisol levels were below 1. 8 µg/dL or 50 nmol/L after one, two, three, or seven days following surgery; they therefore required cortisone replacement therapy. Follow-up was for a median time of 11.5 years (range: 2 to 25 years). RESULTS: Clinical and biochemical cure was achieved in 9/15 patients (60%) exclusively after transsphenoidal surgery. Hypopituitarism was observed in four patients; growth hormone deficiency, in two; permanent diabetes insipidus, in one case. CONCLUSIONS: Cushing's disease is rare in children and adolescents. Transsphenoidal surgery is an effective and safe treatment in most of these patients. Plasma cortisol level < 1. 8 µg/dL following surgery is the treatment goal and is a good predictive factor for long-term cure of Cushing's disease.

Objective: Impaired GH secretion usually accompanies Cushing’s syndrome and a variable proportion of patients reportedly fail to recover normal GH secretion after successful treatment. This wide variability is most probably due to differences in the treatment (i.e. surgery and/or radiotherapy), timing of patient re-evaluation after surgery and dynamic tests employed to challenge GH secretion, and hinders a precise assessment of risk of GH deficiency after cure. The aim of the present study is to evaluate GH secretory status after long-term cure of Cushing’s disease achieved by surgery alone. Design and methods: We studied 34 patients (27 females and 7 males, age range 21–68 years) formerly affected by Cushing’s disease. Patients were studied 2–20 years (median 3.3 years) following remission of hypercortisolism; all patients underwent transsphenoidal surgery with the removal of an ACTH-secreting adenoma; repeat pituitary surgery for relapse was performed in two patients while bilateral adrenalectomy was necessary in two patients. In all subjects, the GH response to GHRH+arginine stimulation was evaluated. At the time of testing, 13 patients were still on steroid replacement therapy. Results: In long-term surgical remission, 22 patients (65.0%) presented subnormal GH secretion; partial GH deficiency (GH peak <16.5 μg/l) was found in 11 patients and severe GH deficiency (GH peak <9 μg/l) in another 11. Male gender and length of hypercortisolism were risk factors for postsurgical GH deficiency. Conclusions: This study demonstrates the presence of GH deficiency in a high percentage of patients with Cushing’s disease after long-term remission of hypercortisolism obtained by surgery alone. Male gender and length of hypercortisolism are the most significant predictors of postsurgical GH deficiency. This finding is significant as it highlights that even the most favourable therapeutical course, i.e. remission achieved by surgery alone, is accompanied by impaired GH secretion. Assessment of GH secretion is therefore recommended for all patients cured from Cushing’s disease, even if not submitted to radiotherapy. Studies on the clinical impact of GH deficiency and the use of GH replacement therapy seem warranted in patients cured from Cushing’s disease.

Object Primary empty sella syndrome (ESS) results from herniation of arachnoid mater into the pituitary fossa. It has been suggested to have a negative effect on pituitary surgery; however, outcomes in this cohort have not been defined. This study was performed to determine the effect of ESS on immediate and long-term biochemical outcome after pituitary surgery for Cushing's disease (CD). Methods Using a matched cohort study design, the authors followed patients treated with pituitary surgery for CD with and without ESS. Complete ESS was defined as pituitary gland height ≤ 2 mm, whereas partial ESS was defined as pituitary gland height > 2 mm but less than three-quarters of the total sellar depth. The primary end points were immediate and long-term biochemical outcome. Cerebrospinal fluid leaks were recorded as a secondary end point. Results Seventy-eight patients with CD and primary ESS were identified and matched with 78 patients with CD without ESS. After surgical management, immediate biochemical remission was achieved in 69 patients (88%) with ESS and 75 controls (96%, p = 0.10). Long-term remission was achieved in most patients in both groups (5-year cure: 85% vs 92%, p = 0.10). Among patients with ESS, the presence of complete ESS predicted a worse long-term outcome (p = 0.04). Intraoperative CSF leaks were significantly more frequent with ESS (54% vs 24%, p < 0.001), and despite sellar floor repair, the rate of postoperative CSF leaks was also increased (6% vs 3%, p = 0.27). Conclusions Biochemical outcome after pituitary surgery for CD was worse in patients with complete ESS, and the risk of a CSF leak was increased with both partial and complete ESS. However, as outcome remains superior to those following alternative therapies and the biology of these tumors is unchanged in the setting of ESS, pituitary surgery should remain the initial treatment of choice.

AbstractBilateral adrenalectomy (BLA) is a treatment option for patients with Cushing’s Disease (CD) if transsphenoidal pituitary surgery fails or is not a therapeutic option. For most patients, BLA eliminates endogenous glucocorticoid and mineralocorticoid production, but for a small number of patients, endogenous secretion of adrenal hormones from adrenal tissue continues or recurs, leading to signs and symptoms of hypercortisolism. If adrenal tissue is confined to the adrenal bed, it is considered adrenal remnant tissue, while if it is outside the adrenal bed, it is considered adrenal rest tissue. We retrospectively evaluated morning serum cortisol, nighttime serum cortisol, nighttime salivary cortisol, and 24-h urine free cortisol on at least three occasions in 10 patients suspected of having endogenous cortisol production. Imaging of adrenal remnant tissue was also reviewed. Ten of 51 patients who underwent BLA during this time period had adrenal remnant/rest tissue marked by detectable endogenous glucocorticoid production; 9 of the 10 patients had signs and symptoms of hypercortisolism. Localization and treatment proved difficult. We conclude that the incidence of adrenal remnant/rest tissue in those undergoing BLA following unsuccessful pituitary surgery was 12% although there may have been a selection bias affecting this prevalence. The first indication of remnant tissue occurrence is a reduction in glucocorticoid replacement with symptoms of hypercortisolism. If this occurs, endogenous cortisol production should be tested for by cortisol measurements using a highly specific cortisol assay while the patient is taking dexamethasone or no glucocorticoid replacement. Endocrinologists need to monitor the development of both adrenal remnant tissue and Nelson’s syndrome following BLA.

Suppression Test

Transsphenoidal pituitary surgery (TSS) remains the treatment of choice for Cushing's disease (CD). Despite the widespread acceptance of this procedure as the first line treatment in CD, the indication of a second TSS in not cured or relapsed DC patients is not consensus. We report the results of TSS in 108 patients with CD (a total of 117 surgeries). The mean postoperative follow-up period was 6 years. Remission was defined as clinical and laboratorial signs of adrenal insufficiency, period of glucocorticoid dependence, serum cortisol suppression on oral 1-mg dexamethasone overnight suppression test and clinical remission of hypercortisolism. We evaluated 103 patients with CD by the time of the first TSS. Fourteen patients underwent second TSS (5 had already been operated in others centers; in 5 patients the first surgery was not curative; in 4 patients CD relapsed). Remission rates were 85.4% and 28.6% (p < 0.001) after first and second TSS, respectively. In microadenomas, remission rates were higher than macroadenomas (94.9% vs. 73.9%; p = 0.006). In patients with negative pituitary imaging remission rates were 71.4% (p = 0.003; vs. microadenomas). Postoperative complications were: transient diabetes insipidus, definitive diabetes insipidus, hypopituitarism, stroke and one death. Only hypopituitarism was more frequent after second TSS (p = 0.015). In conclusion, TSS for CD is an effective and safe treatment. The best remission rates were observed at the first surgery and in microadenomas. The low remission rates after a second TSS suggest that this approach could not be a good therapeutic choice when the first one was not curative.
