Abstract
Context Intensity-modulated radiotherapy (IMRT) is a modern precision radiotherapy technique for the treatment of the pituitary adenoma. Objective Aim to investigate the efficacy and toxicity of IMRT in treating Cushing's Disease (CD). Methods 70 of 115 patients with CD treated with IMRT at our institute from April 2012 to August 2021 were included in the study. The radiation doses were usually 45-50 Gy in 25 fractions. After IMRT, endocrine evaluations were performed every 6 months and magnetic resonance imaging (MRI) annually. Endocrine remission was defined as suppression of 1 mg dexamethasone test (DST) or normal 24-hour urinary free cortisol level (24hUFC). The outcome of endocrine remission, endocrine recurrence, tumor control and complications were retrieved from medical record. Results At a median follow-up time of 36.8 months, the endocrine remission rate at 1, 2, 3 and 5 years were 28.5%, 50.2%, 62.5% and 74.0%, respectively. The median time to remission was 24 months (95%CI: 14.0-34.0). Endocrine recurrence was found in 5 patients (13.5%) till the last follow-up. The recurrence-free rate at 1, 2, 3 and 5 years after endocrine remission was 98.2%, 93.9%, 88.7% and 88.7%, respectively. The tumor control rate was 98%. The overall incidence of new onset hypopituitarism was 22.9%, with hypothyroidism serving as the most common individual axis deficiency. Univariate analysis indicated that only higher Ki-67 index (P=0.044) was significant favorable factors for endocrine remission. Conclusion IMRT was a highly effective second-line therapy with low side effect profile for CD patients. Endocrine remission, tumor control and recurrence rates were comparable to previous reports on FRT and SRS.

Abstract
OBJECTIVE Recurrent Cushing disease (CD) is characterized by the reappearance of clinical and hormonal aspects of hypercortisolism that occur more than 6 months after an initial post-treatment remission. METHODS We performed a systematic review and meta-analysis to synthesize the evidence about remission and complication rates after transsphenoidal surgery (TSS) radiotherapy (RT) and medical therapy (MT) in recurrent CD patients. A quantitative systematic review was performed. Article selection was performed by searching MEDLINE (using PubMed), and Cochrane electronic bibliographic databases through 2020. RESULTS We noted 61 articles described therapeutic management of recurrent CD patients with representative outcome. A total of 723 patients received different therapeutic modality for their recurrent CD. The remission rates were 0.65 (95% confidence interval [CI] 0.60-0.70), 0.57 (95% CI 0.51-0.63), and 0.75 (95% CI 0.60-0.86) in the TSS, RT, and MT subgroups, respectively. The total remission rate after therapeutic approaches on recurrent CD patients was 0.64 (95% CI 0.60-0.68). A test for subgroup differences revealed there was a statistically significant difference between different subgroups (P = 0.01). The post hoc test showed that in comparison with RT, TSS (P = 0.0344) and MT (P = 0.0149) had a higher rate of remission. However, there was no statistically significant difference between separate therapeutic modalities in terms of complications including diabetes insipidus (P = 1.0) and hypopituitarism (P = 0.28). CONCLUSIONS Compared MT and TSS, RT has a statistically lower rate of remission. Although there is robust superiority of surgery over RT, interpretation of MT data must considered with caution due to the small number of included cases and wide CI range.

Abstract
AIM To investigate the association of bone mineral density (BMD) Z-scores with early-postoperative remission rate and clinical parameters in patients with Cushing's disease (CD). METHODS We retrospectively evaluated the records of patients diagnosed with CD. After the exclusion of 230 patients, 87 CD patients were finally enrolled. BMD was determined by dual-energy x-ray absorptiometry (DXA) at the lumbar spine 1-4 (L1-4) and left femur. Early-postoperative remission was defined as a morning cortisol concentration on the first day after surgery of less than 5 μg/dL. The diagnosis of BMD "below the expected range for age" was defined as a Z-score≤-2.00 standard deviations. RESULTS DXA results were not significantly associated with early postoperative remission. They also did not significantly differ between eugonadal and menopausal groups. Preoperative morning cortisol significantly negatively but weakly correlated with Z-score of the total femur, while preoperative adrenocorticotropic hormone/cortisol ratio positively but weakly correlated with DXA results of L1-4. CONCLUSION The severity of bone loss was not significantly related to the failure of transsphenoidal surgery for Cushing's disease.

Abstract
PURPOSE Identify presurgical factors associated with surgical remission in Cushing's disease (CD). METHODS All the patients with ACTH-dependent Cushing's Syndrome in follow-up at our centre between 2014-2021 (n=40) were identified. Those patients with CD diagnosis who underwent transsphenoidal surgery by the same neurosurgeon (n=32) were included. Surgical remission was defined as plasma cortisol <1.8μg/dl and normal or low urinary free cortisol (UFC) after surgery. RESULTS Sixty-three per cent (n=20) were women, and the mean age at diagnosis was 42.3±17.9 years. Six patients had macroadenomas, 17 had microadenomas, and in the other 9 patients, no pituitary lesion was identified on the MRI. Seven patients were previously operated on in another centre. Surgical remission was achieved in 75% (n=24). Only three patients experienced recurrence. No association between pre-surgical demographic (age, sex, comorbidities) or hormonal (UFC, ACTH, late-night salivary cortisol levels) characteristics and the probability of surgical remission was observed. The only variable associated with a greater chance of remission was the presurgical visualisation of the adenoma on MRI (OR 8.3, P=0.02). It was also observed that patients with a history of a previous pituitary surgery had a lower tendency to achieve remission, although statistical significance was not reached (OR 0.17, P=0.09). CONCLUSIONS In our experience, 75% of patients with CD achieved biochemical cure after the intervention. Surgical remission was up to eight times more frequent in those patients in whom the adenoma was visualised before the intervention, but no other presurgical predictive factors of cure were identified.

Abstract
BACKGROUND Cushing's disease (CD) is a rare disorder of a persistent cortisol excess caused by ACTH-secreting pituitary tumor (corticotropinoma). Transsphenoidal surgery (TSS) is a treatment of choice for СD, which effectiveness range is from 70 to 90%. Recurrence rate after successful treatment is about 25%. If surgical treatment is unsuccessful or recurrence appear, radiation treatment is the next therapeutic option, which effectiveness range is also 90%, but the hypopituitarism rate as side effect of treatment is higher. Preoperative predictors of remission and recurrence are still unexplored what leads to further investigations. AIM Analysis of remission and recurrence rates of pediatric CD after successful treatment according to preoperative MRI and therapeutic option. MATERIALS AND METHODS We conducted a retrospective analysis of 90 pediatric patients with CD who were observed between 1992 and 2020 at the Endocrinology Research Centre. RESULTS The most common clinical symptoms of CD were weight gain [94%] and growth retardation [72%]. Pituitary tumor was detected on radiological imaging in 53/90 patients [59%], there were no signs of visible adenoma in 37/90 of patients [41%]. 63 of 90 patients underwent TSS (70%), 27 patients underwent radiosurgery (30%). Remission rate after TSS was 71% [45/63], after radiosurgery - 85% [23/27]. There were no significant differences in remission rates after radical treatment according to preoperative MRI results (P=0.21 after TSS and P=0.87 after radiosurgery, х2 analysis). Recurrence after successful treatment was diagnosed in 10 patients. There were no significant differences in time to recurrence according to preoperative MRI results (P=0.055, х2 analysis). Time to recurrence was statistically different after TSS compared to radiosurgery (P=0.007, Kaplan-Meier analysis) and in the group with developed adrenal insufficiency in the early postoperative period (P=0.04, Kaplan-Meier analysis). Analysis of side effect of treatment showed that the frequency of growth hormone and gonadotrophin deficiency was statistically higher after radiosurgery (р<0.01, Kruskel-Wallis ANOVA test). Diabetes insipidus was diagnosed only after TSS. CONCLUSION Results of our study didn`t allow to use MRI-results as predictor of effectiveness treatment in pediatric CD. Therapeutic option has an impact on time to recurrence, not on recurrence rates. The frequency of growth hormone and gonadotrophin deficiency was statistically higher after radiosurgery compared to TSS. Further studies are needed to identify predictors of remission and recurrence in CD.>< 0.01, Kruskel-Wallis ANOVA test). Diabetes insipidus was diagnosed only after TSS.

Abstract
INTRODUCTION The relationship between growth hormone (GH)/insulin-like growth factor 1 (IGF-1) and glucocorticoids (GC) was examined in various studies. Long-term GC treatment was shown to decrease GH concentration and, interestingly, to increase IGF-1 concentration. We performed a retrospective study in order to examine how preoperative IGF-1 concentrations vary within the reference range and if tertiles of age- and sex-adjusted normal IGF-1 are predictive for early postoperative remission in the patients with Cushing's Disease (CD). PATIENTS AND METHODS Patients diagnosed with CD were retrospectively evaluated. After the exclusion of 67 patients, a final cohort of 250 CD patients were included. Age- and sex-adjusted normal IGF-1 levels were divided into tertiles (T1, T2 and T3). Early postoperative remission was defined as a nadir morning cortisol concentration measured within the first 3 consecutive days following surgery of less than 5 µg/dL (138 nmol/L). RESULTS Early postoperative remission rate was the lowest in T1 and highest in T3; 49.1% (n = 28) versus 77.3% (n = 75), p = .001, respectively. Binary logistic regression analysis showed the remission rate in T3 was three times higher than that in T1 (p = .003). Cortisol and ACTH concentration were significantly higher and GH concentrations were significantly lower in T1 compared to those in the other two tertiles. CONCLUSIONS As the first study evaluating the correlation between early postoperative remission rate in patients with CD and the tertiles of normal age- and sex-adjusted IGF-1 levels, we have shown that higher IGF-1 levels could predict better outcome in CD.

Abstract
OBJECTIVE Transsphenoidal surgery (TSS) is the first-line treatment of patients with Cushing's disease (CD). However, biochemical remission rates after TSS for CD vary from 59 to 95%, and the predictors of surgical outcomes remain unclear. The aim of this study was to identify the predictors of early outcomes in patients with CD treated with TSS. METHODS The clinical features and outcomes of CD patients who underwent TSS between February 2000 and September 2019 at the Peking Union Medical College Hospital were collected from medical records and analyzed. Uni- and multivariate odds ratio (OR) analyses were performed to identify the predictors of early outcomes in patients with CD. RESULTS A total of 1,045 patients were included. The median age at TSS was 34.0 years (IQR 26.0-45.0), with a female:male ratio of 4.2:1 (844/201). The median duration of symptoms was 46.0 months (IQR 24.0-72.0). After surgery, the overall postoperative immediate remission rate was 73.3%, and 26.7% of patients had persistent hypercortisolism. Univariate analysis demonstrated that the number of operations was correlated with a lower immediate remission rate (OR 0.393, 95% CI 0.266-0.580, p = 0.000), as was tumor size (OR 0.462, 95% CI 0.334-0.639, p = 0.000), the duration of disease (OR 0.996, 95% CI 0.993-0.999, p = 0.003), and preoperative ACTH concentration (0.998, 95% CI 0.996-0.999, p = 0.003). Cavernous sinus invasion has also been identified as an important factor associated with a lower immediate remission rate (OR 0.275, 95% CI 0.166-0.456, p = 0.000). No correlations were detected between the immediate outcomes and age, gender, BMI, the combination of a low- and high-dose dexamethasone suppression test, preoperative morning serum cortisol level, or 24-h urinary free cortisol level (all p > 0.05). The results of multivariate analysis were similar to those of univariate analysis. Preoperative ACTH ≤67.35 ng/L predicted remission with 60.9% sensitivity and 49.5% specificity (AUC 0.553; p = 0.008). A cutoff of ≤64.5 months for disease duration predicted immediate remission with 40.5% sensitivity and 71.0% specificity (AUC 0.552; p = 0.01). CONCLUSION Early outcomes of TSS in CD patients can be predicted by factors including the number of operations, duration of disease, tumor invasion, tumor size, and preoperative ACTH concentration. These predictors can be used to improve the perioperative management of CD patients.

Abstract
Accurate classification of postsurgical remission, and early recognition of recurrence are crucial to timely treat and prevent excess mortality in Cushing's Disease, yet the criteria used to define remission are variable and there is no consensus to define recurrence. Remission is defined as postsurgical hypocortisolemia, but delayed remission may occur. Recurrence is the return of clinical manifestations with biochemical evidence of hypercortisolism. The proper combination of tests and their timing are controversial. Reliable predicting tools may lead to earlier diagnosis upon recurrence. Many factors have been studied independently for prediction with variable performance. Novel artificial intelligence approaches seek to integrate these variables into risk calculators and machine-learning algorithms with an acceptable short-term predictive performance but lack longer-term accuracy. Prospective studies using these approaches are needed. This review summarizes the evidence behind the definitions of remission and recurrence and provide an overview of the available tools to predict and/or diagnose them.

Braun LT, Rubinstein G, Zopp S, Vogel F, Schmid-Tannwald C, Escudero MP, Honegger J, Ladurner R, Reincke M. Recurrence after pituitary surgery in adult Cushing's disease: a systematic review on diagnosis and treatment. Endocrine 2020; 70:218-231. [PMID: 32743767 PMCID: PMC7396205 DOI: 10.1007/s12020-020-02432-z] [Citation(s) in RCA: 32] [Impact Index Per Article: 8.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/13/2020] [Accepted: 07/20/2020] [Indexed: 12/17/2022]
Abstract
PURPOSE Recurrence after pituitary surgery in Cushing's disease (CD) is a common problem ranging from 5% (minimum) to 50% (maximum) after initially successful surgery, respectively. In this review, we give an overview of the current literature regarding prevalence, diagnosis, and therapeutic options of recurrent CD. METHODS We systematically screened the literature regarding recurrent and persistent Cushing's disease using the MESH term Cushing's disease and recurrence. Of 717 results in PubMed, all manuscripts in English and German published between 1980 and April 2020 were screened. Case reports, comments, publications focusing on pediatric CD or CD in veterinary disciplines or studies with very small sample size (patient number < 10) were excluded. Also, papers on CD in pregnancy were not included in this review. RESULTS AND CONCLUSIONS Because of the high incidence of recurrence in CD, annual clinical and biochemical follow-up is paramount. 50% of recurrences occur during the first 50 months after first surgery. In case of recurrence, treatment options include second surgery, pituitary radiation, targeted medical therapy to control hypercortisolism, and bilateral adrenalectomy. Success rates of all these treatment options vary between 25 (some of the medical therapy) and 100% (bilateral adrenalectomy). All treatment options have specific advantages, limitations, and side effects. Therefore, treatment decisions have to be individualized according to the specific needs of the patient.

Abstract
In patients with Cushing's disease (CD), prompt diagnosis and treatment are essential for favorable long-term outcomes, although this remains a challenging task. The differential diagnosis of CD is still difficult in some patients, even with an organized stepwise diagnostic approach. Moreover, despite the use of high-resolution magnetic resonance imaging (MRI) combined with advanced fine sequences, some tumors remain invisible. Surgery, using various surgical approaches for safe maximum tumor removal, still remains the first-line treatment for most patients with CD. Persistent or recurrent CD after unsuccessful surgery requires further treatment, including repeat surgery, medical therapy, radiotherapy, or sometimes, bilateral adrenalectomy. These treatments have their own advantages and disadvantages. However, the most important thing is that this complex disease should be managed by a multidisciplinary team with collaborating experts. In addition, a personalized and individual-based approach is paramount to achieve high success rates while minimizing the occurrence of adverse events and improving the patients' quality of life. Finally, the recent new insights into the pathophysiology of CD at the molecular level are highly anticipated to lead to the introduction of more accurate diagnostic tests and efficacious therapies for this devastating disease in the near future.

Abstract
Cushing's disease (CD) is a rare endocrine condition caused by a corticotroph pituitary tumor that produces adrenocorticotropic hormone. The current state of knowledge of CD treatment is presented in this article including factors that can be helpful in predicting remission and/or recurrence of the disease. The primary goals in CD treatment are quick diagnosis and effective, prompt treatment as the persistent disease is associated with increased morbidity and mortality. Cooperation of a team consisting of experienced pediatrician/adult endocrinologist, neuroradiologist, transsphenoidal neurosurgeon and (if necessary) radiotherapist contribute to the best treatment effects.

Abstract
RATIONALE Knosp grade 4 adrenocorticotropic hormone (ACTH)-secreting pituitary adenoma is a rare cause of Cushing disease. After the 1st surgery, the remission rate among these patients is extremely low. PATIENT CONCERNS We presented a case of a 33-year-old female with classical Cushingoid symptoms. Further investigations revealed ATCH-dependent hypercortisolemia, as well as a Knosp grade 4 pituitary macroadenoma. DIAGNOSIS Cushing disease, caused by a Knosp grade 4 pituitary macroadenoma. INTERVENTIONS The patient underwent endoscopic endonasal transsphenoidal surgery with the assistance of intraoperative transsphenoidal Doppler and image-guidance devices. OUTCOMES Pathologic examinations confirmed that the lesion was an ACTH-secreting pituitary adenoma. The patient was in biochemical remission after surgery. Her postoperative magnetic resonance imaging showed gross-total tumor resection. There was no evidence of recurrence during the 1-year follow-up. LESSONS With intraoperative Doppler and image-guidance, gross-total resection and biochemical remission can be achieved in Cushing disease when the internal carotid artery is completely encased by the pituitary adenoma.

Abstract
BACKGROUND This study investigated the outcome of transsphenoidal surgery (TSS) for Cushing disease (CD) and the influence of our surgical strategy on remission rates and postoperative pituitary function. PATIENTS AND METHODS We retrospectively reviewed data from 71 patients with CD who underwent microscope navigation TSS (MN-TSS) in Saint-Luc Hospital between 1996 and 2017. True remission was defined as normal fasting cortisol level, normal 24-hour urinary free cortisol, or continued need for hydrocortisone replacement for 1 year after surgery. RESULTS Overall remission rate after 1 or repeated MN-TSS was 83%. Highest remission rate was found in patients with macroadenomas (92%). Successful first MN-TSS was correlated with a high final remission rate (95%), whereas failed first MN-TSS was correlated with a low final remission rate (36%). Although day 1 cortisol levels were significantly lower in patients with long-term remission, high levels were still observed in a few patients, especially those who had had CD for many years. We found a low rate of postoperative pituitary long-term hypofunction (9.7%). CONCLUSIONS MN-TSS is a safe and effective procedure to treat CD, allowing remission rates of 83%. One-year remission period after first surgery is correlated with a final remission rate of 95%. Although day 1 morning cortisol value is the most significant predictor for long-term remission, some patients with CD for many years may keep high postoperative cortisol levels and be in later remission, likely because of secondary adrenal hyperplasia. Our focused approach with microscope navigation resulted in low rates of postoperative pituitary hypofunction and kept a recurrence rate comparable to that in the literature.

Abstract
Transsphenoidal surgery is the main treatment of patients with adrenocorticotropic hormone (ACTH)-secreting pituitary adenomas. Although biochemical remission occurs in most patients undergoing operations at specialized centers, the recurrence risk is significant. Visualization of microadenomas on preoperative imaging and confirmation of ACTH-positive adenomas have been associated with higher remission rates. Low cortisol levels in the first 2 weeks postoperatively have been associated with durable remission; however, recurrence cannot be excluded by any cortisol threshold. The decision to perform a pituitary reoperation is based on this parameter; the protocols are institution specific. Patients with Cushing's disease warrant lifelong endocrinologic surveillance.

Abstract
OBJECT The primary objective was to assess the remission rate, and the secondary objectives were to evaluate the early complications and recurrence rate and to define the predictive factors for the remission and recurrence rates. PATIENTS AND METHODS This prospective single-center study included 230 consecutive patients, operated on by a single surgeon for Cushing's disease via a transsphenoidal endoscopic endonasal approach, over a 6-year period (2008-2013). The patients included in this series were all adults (>18 years of age), who presented with clinical and biological characteristics of Cushing's disease confirmed based on dedicated MRI pituitary imaging. Biochemical remission was defined as a postoperative serum cortisol level <5 μg/dl on the 2nd day following surgery that required glucocorticoid replacement therapy. RESULTS The remission rate for the global population (n = 230) with a follow-up of 21 ± 19.2 months concerned 182 patients (79.1%) divided into 132 patients (82.5%) with positive MRI and 50 patients (71.4%) with negative MRI with no statistically significant difference (p = 0.077). Complications occurred in 77 patients with no deaths. A total of 22% of patients had transient diabetes insipidus and 6.4% long-term diabetes insipidus, and no postoperatively CSF leakage was observed. The recurrence rate was 9.8% with a mean time of 32.7 ± 15.2 months. The predictive factors for the remission rate were the presence of pituitary microadenoma and a positive histology. No risk factors were involved regarding the recurrence rate. CONCLUSION Whatever the MRI results, the transsphenoidal endonasal endoscopic approach remains the gold standard treatment for Cushing's disease. It was maximally effective with a remission rate of 79.1% and lower morbidity.

Abstract
PURPOSE Pituitary macroadenomas (MACs) represent 10-30 % of Cushing's disease (CD) cases. The aim of this study was to report the clinical, laboratorial and imaging features and postsurgical outcomes of microadenoma (MIC) and MAC patients. METHODS Retrospective study with 317 CD patients (median 32 years old, range 9-71 years) admitted between 1990 and 2014, 74 (23.3 %) of whom had MAC. RESULTS Hirsutism, plethora facial, muscular weakness and muscular atrophy were more frequent in the MIC patients. Nephrolithiasis, osteopenia, hyperprolactinaemia and galactorrhoea were more prevalent in MAC patients. The morning serum cortisol (Fs), nocturnal salivary cortisol (NSC), nocturnal Fs (Fs 2400 h), low- and high-dose dexamethasone suppression test results and CRH and desmopressin test results were similar between the subgroups. MIC patients showed higher urinary cortisol at 24 h (UC), and MAC patients presented higher ACTH levels but lower Fs/ACTH, Fs 2400 h/ACTH, NSC/ACTH and UC/ACTH ratios. There were negative correlations of tumour size with Fs/ACTH, Fs 2400 h/ACTH, NSC/ACTH and UC/ACTH ratios. Overall, the postsurgical remission and recurrence rates were similar between MIC and MAC. However, patients in remission (MIC + MAC) showed smaller tumour diameters and a lower prevalence of invasion and extension on MRI. CONCLUSIONS Despite exhibiting higher plasma ACTH levels, CD patients with MAC presented lower cortisol/ACTH ratios than did patients with MIC, with a negative correlation between tumour size and cortisol/ACTH ratios. The overall postsurgical remission and recurrence rates were similar between MIC and MAC patients, with those with larger and/or invasive tumours showing a lower remission rate.

Abstract
The management of critically ill Cushing's disease (CD) patients is extremely challenging. Pasireotide is indicated for the treatment of CD patients when pituitary surgery is unfeasible or has not been curative, but no data are available about the use of this drug as pre-operative treatment in critically ill patients. We report the effects of presurgical pasireotide therapy in CD patients in whom hypercortisolism caused life-threatening hypokalemia, alkalosis, and cardio-respiratory complications precluding surgical approach. Clinical, biochemical, and radiological data of two critically ill patients with ACTH-secreting pituitary macroadenoma, before and during first-line presurgical pasireotide treatment (600 μg s.c. bid). During the first 21 days of treatment, pasireotide therapy induced a rapid, partial decrease of plasma ACTH, serum cortisol, and urinary free cortisol levels, with the consequent normalization of serum potassium concentration and arterial blood gases parameters, in both the patients. They did not experience unmanageable side effects and underwent endoscopic transsphenoidal surgery after 4 weeks of effective treatment. Pre-operative MRI evaluation did not show pituitary tumor shrinkage. Surgical cure of CD was obtained in the first patient, while debulking allowed the pharmacological control of hypercortisolism in the second case. We suggest that pasireotide can induce a rapid improvement of clinical and metabolic conditions in critically ill CD patients in whom surgical approach is considered hazardous and need to be delayed.

Abstract
OBJECTIVE Corticotroph macroadenomas are a rare cause of Cushing's disease (CD), but their properties are not well-recognised. The aim of this study was to evaluate the clinical and pathological aspects of corticotroph macroadenomas with particular emphasis on proliferation markers and their associations with the efficacy of surgical treatment. DESIGN A prospective cohort study was conducted in a tertiary referral centre in Poland. METHODS In total, 59 patients with CD (20 macroadenomas and 39 microadenomas) were included in this study. Hormonal and imaging parameters, histopathological and ultrastructural features of the corticotroph tumours and the early surgical outcomes were evaluated. RESULTS ACTH and ACTH/cortisol ratios were higher in macroadenomas (P<0.001 and P=0.002 respectively). Greater tumour volumes were associated with higher Ki-67 and p53 expression (Ptrend=0.009 and Ptrend=0.024 respectively) and the rates of sparsely granulated adenomas (Ptrend=0.036). Immediate postoperative remission and early biochemical remission rates were lower in macroadenomas compared to microadenomas (P<0.001). A logistic regression model showed that the immediate postoperative remission or early biochemical remission depended on tumour volume (P=0.005 and P=0.006 respectively) and invasiveness based on Knosp grades 3 and 4 for macroadenomas and a lack of surgical pseudocapsule for microadenomas (P=0.004 and P=0.007 respectively). CONCLUSION Corticotroph macroadenomas differ from the more common microadenomas not only in terms of hormonal and imaging characteristics but also in terms of immunohistochemical and ultrastructural features and proliferation markers. The early effectiveness of surgery depends primarily on tumour volume and invasiveness.

Abstract
The purpose of this study was to review therapeutic outcomes and comorbidities of patients with Cushing's disease (CD) in a single center. We conducted a retrospective study of 33 patients with CD undergoing transsphenoidal surgery from January 2007 to February 2014 (27 females and 6 males, median age 38 years, range 18-71 years). The diagnosis of Cushing's syndrome was established on the basis of the patient's history, characteristic clinical features, and laboratory data including an elevated 24-h urinary free cortisol level, lack of serum cortisol suppression after dexamethasone suppression tests and an elevated midnight cortisol level. In 28/33 patients, the tumor was visualized on MR of the sellar region, while in 5 it was diagnosed using an inferior petrosal sinus sampling. Out of the 33 patients, 10 had macroadenoma and the remaining 23 had microadenoma. Twenty-one patients (63.6%) had hypertension, 17 (51.5%) dyslipidemia, and 7 (21.2%) had type 2 diabetes or impaired glucose tolerance. The median follow-up period was 28 months. Remission after transsphenoidal surgery was achieved in 78.8% of patients, while 7 patients failed to achieve disease remission. Those patients were treated with second-line treatment modalities (second operation, radiotherapy, bilateral adrenalectomy, and/or ketoconazole). One patient rejected all the treatment modalities after surgery. Cumulative remission after all the treatment modalities was achieved in 87.9% patients. Patients with Cushing's disease should be managed in centers with much experience due to high patient load. In our Center, the remission of the disease has been achieved in 78.8% of the patients following transsphenoidal surgery. Multimodal treatment which included radiotherapy and medical treatment led to biochemical remission of the disease in 87.9% of patients.

A role for 11C-methionine PET imaging in ACTH-dependent Cushing's syndrome. Eur J Endocrinol 2015; 173:M107-20.

Abstract
OBJECTIVE We report our experience of functional imaging with (11)C-methionine positron emission tomography-computed tomography (PET-CT) co-registered with 3D gradient echo (spoiled gradient recalled (SPGR)) magnetic resonance imaging (MRI) in the investigation of ACTH-dependent Cushing's syndrome. DESIGN Twenty patients with i) de novo Cushing's disease (CD, n=10), ii) residual or recurrent hypercortisolism following first pituitary surgery (±radiotherapy; n=8) or iii) ectopic Cushing's syndrome (n=2) were referred to our centre for functional imaging studies between 2010 and 2015. Six of the patients with de novo CD and five of those with persistent/relapsed disease had a suspected abnormality on conventional MRI. METHODS All patients underwent (11)C-methionine PET-CT. For pituitary imaging, co-registration of PET-CT images with contemporaneous SPGR MRI (1 mm slice thickness) was performed, followed by detailed mapping of (11)C-methionine uptake across the sella in three planes (coronal, sagittal and axial). This allowed us to determine whether suspected adenomas seen on structural imaging exhibited focal tracer uptake on functional imaging. RESULTS In seven of ten patients with de novo CD, asymmetric (11)C-methionine uptake was observed within the sella, which co-localized with the suspected site of a corticotroph microadenoma visualised on SPGR MRI (and which was subsequently confirmed histologically following successful transsphenoidal surgery (TSS)). Focal (11)C-methionine uptake that correlated with a suspected abnormality on pituitary MRI was seen in five of eight patients with residual or recurrent Cushing's syndrome following first TSS (and pituitary radiotherapy in two cases). Two patients elected to undergo repeat TSS with histology confirming a corticotroph tumour in each case. In two patients with the ectopic ACTH syndrome, (11)C-methionine was concentrated in sites of distant metastases, with minimal uptake in the sellar region. CONCLUSIONS (11)C-methionine PET-CT can aid the detection of ACTH-secreting tumours in Cushing's syndrome and facilitate targeted therapy.

Abstract
Crooke's cell adenomas are a rare type of pituitary neoplasm. They produce adrenocorticotropic hormone causing Cushing's disease or may be endocrinologically silent. These tumors are usually invasive, may exhibit aggressive clinical behavior, and often recur with a low success of cure after reoperation and/or radiotherapy. Due to their rarity, they present great difficulties in assessing prognosis, treatment, and clinical management. Neurosurgeons and physicians dealing with pituitary adenomas diagnosed as Crooke's cell adenomas have to be aware of their potential clinical aggressiveness to plan strict follow-up of patients and eventual multimodality treatment. We review here the published cases of Crooke's cell tumors, as well as the clinical and histopathological characteristics of these unusual neoplasms.

Abstract
Cushing's disease (CD), or pituitary-dependent Cushing's syndrome, is a severe endocrine disease caused by a corticotroph pituitary tumor and associated with increased morbidity and mortality. The first-line treatment for CD is pituitary surgery, which is followed by disease remission in around 78% and relapse in around 13% of patients during the 10-year period after surgery, so that nearly one third of patients experience in the long-term a failure of surgery and require an additional second-line treatment. Patients with persistent or recurrent CD require additional treatments, including pituitary radiotherapy, adrenal surgery, and/or medical therapy. Pituitary radiotherapy is effective in controlling cortisol excess in a large percentage of patients, but it is associated with a considerable risk of hypopituitarism. Adrenal surgery is followed by a rapid and definitive control of cortisol excess in nearly all patients, but it induces adrenal insufficiency. Medical therapy has recently acquired a more important role compared to the past, due to the recent employment of novel compounds able to control cortisol secretion or action. Currently, medical therapy is used as a presurgical treatment, particularly for severe disease; or as postsurgical treatment, in cases of failure or incomplete surgical tumor resection; or as bridging therapy before, during, and after radiotherapy while waiting for disease control; or, in selected cases, as primary therapy, mainly when surgery is not an option. The adrenal-directed drug ketoconazole is the most commonly used drug, mainly because of its rapid action, whereas the glucocorticoid receptor antagonist, mifepristone, is highly effective in controlling clinical comorbidities, mainly glucose intolerance, thus being a useful treatment for CD when it is associated with diabetes mellitus. Pituitary-directed drugs have the advantage of acting at the site responsible for CD, the pituitary tumor. Among this group of drugs, the dopamine agonist cabergoline and the somatostatin analog pasireotide result in disease remission in a consistent subgroup of patients with CD. Recently, pasireotide has been approved for the treatment of CD when surgery has failed or when surgery is not an option, and mifepristone has been approved for the treatment of Cushing's syndrome when associated with impairment of glucose metabolism in case of the lack of a surgical indication. Recent experience suggests that the combination of different drugs may be able to control cortisol excess in a great majority of patients with CD.

Abstract
CONTEXT We have recently reported somatic mutations in the ubiquitin-specific protease USP8 gene in a small series of adenomas of patients with Cushing's disease. OBJECTIVE To determine the prevalence of USP8 mutations and the genotype-phenotype correlation in a large series of patients diagnosed with Cushing's disease. DESIGN We performed a retrospective, multicentric, genetic analysis of 134 functioning and 11 silent corticotroph adenomas using Sanger sequencing. Biochemical and clinical features were collected and examined within the context of the mutational status of USP8, and new mutations were characterized by functional studies. PATIENTS A total of 145 patients who underwent surgery for an ACTH-producing pituitary adenoma. MAIN OUTCOMES MEASURES Mutational status of USP8. Biochemical and clinical features included sex, age at diagnosis, tumor size, preoperative and postoperative hormonal levels, and comorbidities. RESULTS We found somatic mutations in USP8 in 48 (36%) pituitary adenomas from patients with Cushing's disease but in none of 11 silent corticotropinomas. The prevalence was higher in adults than in pediatric cases (41 vs 17%) and in females than in males (43 vs 17%). Adults having USP8-mutated adenomas were diagnosed at an earlier age than those with wild-type lesions (36 vs 44 y). Mutations were primarily found in adenomas of 10 ± 7 mm and were inversely associated with the development of postoperative adrenal insufficiency. All the mutations affected the residues Ser718 or Pro720, including five new identified alterations. Mutations reduced the interaction between USP8 and 14-3-3 and enhanced USP8 activity. USP8 mutants diminished epidermal growth factor receptor ubiquitination and induced Pomc promoter activity in immortalized AtT-20 corticotropinoma cells. CONCLUSIONS USP8 is frequently mutated in adenomas causing Cushing's disease, especially in those from female adult patients diagnosed at a younger age.

Abstract
Octreotide (OCT) is ineffective in patients with Cushing's disease (CD) due to the cortisol-induced down-regulation of somatostatin receptor subtype 2 which was shown to be reversible in vitro by using anti-glucocorticoid mifepristone. This study aimed to verify, in vivo, if mifepristone can modulate response to acute OCT administration in patients with CD. Three men and two postmenopausal women (age 52.5 ± 2 years) with CD were enrolled in the study. OCT (100 μg, s.c.) was administered alone on the first day (OCT-only), and it was then given after mifepristone administration (2 × 200 mg, p.os, 12 and 1 h before OCT), 3 days later (OCT-mif). ACTH and cortisol levels were measured before OCT administration and every 60 min thereafter for 6 h. Baseline ACTH and cortisol values, nadir values and percentage decrements (Δn) were compared during both tests. Mean ACTH-Δn did not differ significantly during the two tests. Both tests induced a <30 % decrease in plasma ACTH in three patients (#1, 2 and 3) and a >50 % decrease in the other two cases (#4 and 5). Cortisol decreased in patients #4 and 5, during both tests. ACTH-Δn did not correlate with morning cortisol nor with urinary free cortisol values. Patients #4 and 5 with the highest ACTH-Δn had the lowest cortisol values after 1 mg of dexamethasone. Brief mifepristone pre-treatment does not modify ACTH and cortisol response to acute OCT administration in CD. However, OCT seems to be more effective in patients with partially preserved cortisol inhibitory feedback.

Abstract
OBJECTIVE Cushing's macroadenoma as a cause of Cushing's disease is less common than microadenoma. The data on nature and behaviour of Cushing's macroadenoma are limited to a few case series. We studied clinical, biochemical and imaging characteristics of macroadenoma and their long-term treatment outcomes. METHOD Retrospective analysis of 40 patients with macroadenoma managed at our centre from 1997 to 2013. RESULTS Of 40 patients, there were 15 (37·5%) males and 25 (62·5%) females. Mean age at presentation was 26·7 ± 9·3 years. Visual field defects and/or cranial nerve palsies were found in 15 cases at presentation. Mean maximum tumour dimension was 20·83 ± 10·74 mm, and parasellar extension was seen in 25 (62·5%) patients. Plasma ACTH/maximum tumour dimension and 8 am serum cortisol/maximum tumour dimension decreased with increasing tumour size. Sixteen patients (40%) had remission (4: immediate, 12: delayed) after first transsphenoidal surgery (TSS). Larger tumour size and parasellar extension were predictors of failure to achieve remission. Four patients relapsed; noticeably all of them had delayed remission. Among the persistent and relapsed cases, second TSS was successful in two of eight patients, whereas 11 of 16 patients achieved remission after a mean duration of 12·14 ± 8·41 months postradiotherapy. CONCLUSION Younger age at presentation and larger tumour size compared with previous series were distinctive features of our series. Large tumour size and parasellar extension were negative predictors of surgical remission. Delayed remission was seen in significant proportion of patients, but one-third later relapsed. Radiotherapy was an effective second-line treatment modality.

Abstract
BACKGROUND The use of ketoconazole has been recently questioned after warnings from the European Medicine Agencies and the Food and Drug Administration due to potential hepatotoxicity. However, ketoconazole is frequently used as a drug to lower circulating cortisol levels. Several pharmacological agents have recently been approved for the treatment of Cushing's disease (CD) despite limited efficacy or significant side effects. Ketoconazole has been used worldwide for more than 30 years in CD, but in the absence of a large-scale study, its efficacy and tolerance are still under debate. PATIENTS AND METHODS We conducted a French retrospective multicenter study reviewing data from patients treated by ketoconazole as a single agent for CD, with the aim of clarifying efficacy and tolerance to better determine the benefit/risk balance. RESULTS Data from 200 patients were included in this study. At the last follow-up, 49.3% of patients had normal urinary free cortisol (UFC) levels, 25.6% had at least a 50% decrease, and 25.4% had unchanged UFC levels. The median final dose of ketoconazole was 600 mg/d. Forty patients (20%) received ketoconazole as a presurgical treatment; 40% to 50% of these patients showed improvement of hypertension, hypokalemia, and diabetes, and 48.7% had normal UFC before surgery. Overall, 41 patients (20.5%) stopped the treatment due to poor tolerance. Mild (<5N, inferior to 5-fold normal values) and major (>5N, superior to 5-fold normal values) increases in liver enzymes were observed in 13.5% and 2.5% of patients, respectively. No fatal hepatitis was observed. CONCLUSIONS Ketoconazole is an effective drug with acceptable side effects. It should be used under close liver enzyme monitoring. Hepatotoxicity is usually mild and resolves after drug withdrawal.

Abstract
The ligand/receptor hepatocyte growth factor (HGF)/c-met signaling system promotes cellular growth and angiogenesis through PI3K/phosphor-Akt and STAT3/phosphor-STAT3 downstream effectors. In this study, we have evaluated the expression of molecules of the HGF/c-met pathway in pituitary adenomas (PA). The expression of HGF, c-met, PI3K (p85αsubunit) pAkt, STAT3, and pSTAT3 was analyzed by immunohistochemistry in an archival series of 30 PA (12 non-functioning and 18 functioning; 25 macroadenomas and 5 microadenomas). PAs expressed all six proteins in tumor epithelial cells. The proportion of c-met(+ve) cells was greater than HGF(+ve) cells (49 ± 19 vs 34 ± 17 %, P < 0.01), the pAkt(+ve) cells greater than PI3K(+ve) cells (39 ± 16.0 vs 1.3 ± 0.5 %, P < 0.001), and the STAT3(+ve) cells greater than active pSTAT3(+ve) cells (14 ± 8 vs 7 ± 6 %, P < 0.01). Furthermore, endothelial Akt immunostaining was detected on the vascular surface area of 17 PAs, in macroadenomas more frequently than in microadenomas (82 vs 18 %). The percentage of immunostained endothelial cells was greater in macro than in microadenomas (19 ± 7 and 7 ± 3 %; P < 0.05). In conclusion, HGF and c-met are widely expressed in PA, and correlate with pAkt expression. These data, together with the finding of pAkt immunostaining on microvascular areas related to tumor size, suggest a major role of the pAKT signaling in tumor growth and angiogenesis. There might be practical implications for the targeted therapy of PA.

Abstract
ACTH-secreting pituitary adenomas (Cushing's disease, CD) are the most frequent cause of Cushing's syndrome. To test whether the size of ACTH-secreting adenomas correlates with the degree of biochemical and clinical features of hypercortisolism, we retrospectively reviewed all newly diagnosed CD patients seen at our institution by two neuro-endocrinologists over a 10-year time period. We documented the number of clinical manifestations and baseline hormonal measurements. There were 37 microadenomas (μAs) and 16 macroadenomas (MAs). We sought to characterize the relationship between tumor size (μA vs. MA) and number of signs and symptoms of hypercortisolism and biochemical assessment of hypercortisolemia. There were no significant differences in mean age, BMI, or prevalence of hypertension and type 2 diabetes between the μA and MA groups. However, the MAs had fewer clinical manifestations of hypercortisolism (29.4% vs. 36.1%, P = 0.02) compared to μAs. There was a higher prevalence of easy bruisability and proximal muscle weakness in the μAs, but otherwise the prevalence of signs and symptoms were similar between groups. The MAs had a lower random serum cortisol (18.2 ± 2.4 vs. 25.9 ± 1.8 mcg/dl, P = 0.018), lower cortisol:ACTH ratio (0.25 ± 0.03 vs. 0.42 ± 0.05, P < 0.048), and lower cortisol:tumor diameter ratio (14.1 ± 2.2 vs. 56.8 ± 7.2, P < 0.0001) than the μAs. We conclude that tumor size does not directly correlate with the extent of hormonal activity in ACTH-secreting adenomas. Biochemical activity and clinical manifestations may be mild even in larger tumors, and therefore a high index of suspicion may be necessary to recognize hypercortisolism in pituitary MAs.

Abstract
Data concerning pregnancy in women with Cushing's disease treated by gamma-knife (GK) are scanty. We present and discuss the course and outcome of five pregnancies in two women with Cushing's disease (CD), the first of whom was treated only by GK, and the second one treated by surgery, GK and ketoconazole. In the first patient, pregnancy was uneventful and full-term. During gestation, plasma ACTH, serum cortisol and 24-h urinary free cortisol (UFC) levels were steady, and always in the normal range for healthy non-pregnant individuals. The newborn was healthy and normal-weight. In the second woman, two pregnancies, occurring 3 years after GK and few months after ketoconazole withdrawal, were interrupted by spontaneous abortion or placental disruption despite normal cortisol levels. This patient became again pregnant 3 years later and delivered vaginally a healthy full-term infant. Seven months after the delivery, the patient became pregnant again and at the 39th week of gestation delivered vaginally a healthy male. Hypoprolactinemia and/or central hypothyroidism occurred in both cases. In women with CD treated by GK, pregnancy can occur. However, pregnancy is at risk even when ACTH and cortisol levels are normalized by treatment. After GK, evaluation of pituitary function is mandatory due to the risk of hypopituitarism.

Abstract
Pituitary apoplexy in patients with adrenocorticotropic hormone (ACTH) producing tumors is a rare occurrence. We report four patients with Cushing's disease harboring ACTH-secreting macroadenomas who presented with pituitary apoplexy. We report the endocrinologic and visual outcomes of these patients after emergent transsphenoidal surgery. A retrospective chart review was performed in 4 patients who presented with pituitary apoplexy from hemorrhage into an ACTH-secreting pituitary adenoma. The patient charts were reviewed for clinical presentation, neuroimaging findings, intraoperative surgical findings, pathologic findings, and postoperative endocrinologic and visual outcomes. All patients presented with acute headaches, nausea, vomiting, and visual loss from optic compression. MR imaging demonstrated a hemorrhagic macroadenoma that was confirmed at surgery. All patients underwent emergent transsphenoidal decompression (within 24 h of presentation). One of these underwent an additional craniotomy to resect residual tumor. Postoperatively, all patients showed significant improvement in visual acuity and visual fields with biochemical remission confirmed on laboratory testing. Significant weight loss as well as resolution of diabetes and hypertension was noted in all cases. All four patients remained in biochemical remission at their most recent follow-up visit (mean 40 months, range: 24-72 months). Excellent endocrine and visual outcomes can be achieved after emergent transsphenoidal surgery in patients with Cushing's disease presenting with pituitary apoplexy. Although the cure rates of non-apoplectic ACTH macroadenomas are generally poor, higher rates of remission can be achieved in cases of pituitary apoplexy. This may be partly due to the effects of tumor infarction.

Abstract
OBJECTIVE Cushing's disease (CD) is a rare endocrine disorder characterized by excess secretion of ACTH due to a pituitary adenoma. Current treatment options are limited and may pose additional risks. A literature review was conducted to assess the holistic burden of CD. DESIGN Studies published in English were evaluated to address questions regarding the epidemiology of CD, time to diagnosis, health-related quality of life (HRQoL), treatment outcomes, mortality, prevalence of comorbidities at diagnosis, and reversibility of comorbidities following the treatment. METHODS a two-stage literature search was performed in Medline, EMBASE, and Science Citation Index, using keywords related to the epidemiology, treatment, and outcomes of CD: i) articles published from 2000 to 2012 were identified and ii) an additional hand search (all years) was conducted on the basis of bibliography of identified articles. RESULTS At the time of diagnosis, 58-85% of patients have hypertension, 32-41% are obese, 20-47% have diabetes mellitus, 50-81% have major depression, 31-50% have osteoporosis, and 38-71% have dyslipidemia. Remission rates following transsphenoidal surgery (TSS) are high when performed by expert pituitary surgeons (rates of 65-90%), but the potential for relapse remains (rates of 5-36%). Although some complications can be partially reversed, time to reversal can take years. The HRQoL of patients with CD also remains severely compromised after remission. CONCLUSIONS These findings highlight the significant burden associated with CD. As current treatment options may not fully reverse the burden of chronic hypercortisolism, there is a need for both improved diagnostic tools to reduce the time to diagnosis and effective therapy, particularly a targeted medical therapy.

Abstract
Adrenocorticotropin (ACTH) producing macroadenomas and pituitary apoplexy are unusual in Cushing' s disease. A 20-year-old man who had been diagnosed Cushing' s disease 2 months ago, presented with sudden headache, nausea, and vomiting. His serum cortisol level was 0.4 μg/dl and ACTH level was 23.9 pg/ml. Magnetic resonance imaging of the pituitary gland disclosed a hemorrhage in the pituitary macroadenoma (22×19 mm). He was treated with IV methylprednisolone immediately and then the symptoms were relieved within the first day of the treatment. The hemorrhagic lesion was resected by transsphenoidal surgery successfully. Impaired secretion of pituitary hormones may be seen after the pituitary apoplexy. We communicate a case with pituitary apoplexy of an ACTH secreting pituitary macroadenoma, causing acute glucocorticoid insufficiency.

Abstract
Prepro-thyrotrophin-releasing hormone (TRH) (178-199), a 22-amino acid cleavage product of the TRH prohormone, has been postulated to act as an adrenocorticotrophin hormone (ACTH)-release inhibitor. Indeed, although in vitro evidence indicates that this peptide may inhibit basal and stimulated ACTH secretion in rodent anterior pituitary primary cultures and cell lines, not all studies concur and no study has as yet evaluated the effect of this peptide in Cushing's disease. The present study aimed to test the effect of preproTRH(178-199) in human tumoural corticotrophs. Twenty-four human ACTH-secreting pituitary tumours (13 macroadenomas, 11 microadenomas) were collected during surgery and incubated with 10 or 100 nm preproTRH(178-199). ACTH secretion was assessed after 4 and 24 h of incubation by immunometric assay and expressed relative to levels observed in control, unchallenged wells (= 100%). Parallel experiments were performed in rat anterior pituitary primary cultures. A clear inhibition of ACTH secretion at 4 and 24 h was observed in 12 specimens (for 10 nm ppTRH: 70 +/- 4% control at 4 h and 83 +/- 5% control at 24 h; for 100 nm ppTRH: 70 +/- 4% control at 4 h and 85 +/- 5% control at 24 h), whereas a mild and short-lasting stimulatory effect was observed in three tumours and no changes in ACTH secretion in the remaining nine tumoural specimens. The inhibitory effect of preproTRH(178-199) was more evident in macroadenomas and significantly correlated with sensitivity to dexamethasone inhibition. Significant inhibition of ACTH secretion by preproTRH(178-199) in rat pituitary cultures was observed after 24 h of incubation. The present study conducted in a large series of human corticotroph tumours shows that preproTRH(178-199) inhibits tumoural ACTH secretion in a sizable proportion of specimens, in close relation to the size of the tumour and its sensitivity to glucocorticoid negative feedback. This appears a promising avenue of research and further studies are warranted to explore the full scope of preproTRH(178-199) as a regulator of ACTH secretion.

Abstract
Cushing's disease, due to pituitary adrenocorticotropic hormone (ACTH) hypersecretion, is the most common etiology of spontaneous excess cortisol production. The majority of pituitary tumors causing Cushing's disease measure <1 cm and the excess morbidity associated with these tumors is mostly due to the effects of elevated, nonsuppressible, ACTH levels leading to adrenal steroid hypersecretion. Elevated circulating cortisol levels lead to abnormal fat deposition, hypertension, diabetes, coronary artery disease, osteoporosis, muscle weakness and psychological disturbances. At experienced centers, initial surgical remission rate via transnasal, transphenoidal resection approaches 80% for tumors less than 1 cm, but may be as low as 30% for larger lesions and long-term recurrence in all groups approaches 25%. Residual disease may be managed with more radical surgery, pituitary-directed radiation, bilateral adrenalectomy, or medical therapy. This paper addresses current and novel therapies in various stages of development for Cushing's disease.

Abstract
Pituitary-dependent hyperadrenocorticism (PDH) is frequent in dogs. Little is known about its presentation in different age groups and its characteristics. Dividing the population under study (n=107) into three age groups we observed that 11.2% were young, 51.4% adults and 37.4% aged. Using magnetic resonance, pituitary tumours were intra-sellar (IS) in 30.8% and extra-sellar (ES) in 62.6% and the pars intermedia (PI) was affected in 6.5%. ES are predominant in females and IS in males (p<0.0001). In the adult-aged population, the ES and PI are predominant, while in the young, the IS predominate (p<0.0001). ACTH concentration was greater in the ES vs. IS (p<0.05). alpha-MSH did not present significant differences according to tumour size, showing a negative correlation (r=-0.47; p<0.01) vs. ACTH. Differences in adenoma size according to gender and their age-related frequency of apparition could be because of different origins of the corticotrophinoma.

Abstract
OBJECTIVE Although numerous studies have shown that transsphenoidal surgery is the best initial treatment for Cushing disease offering 59-95% of success, fewer information is available on the long-term outcome in the subgroup of patients harboring ACTH-secreting macroadenomas. The aims of this study were to analyze our 10-year experience with transsphenoidal surgery in Cushing's disease and to examine whether remission rates were different between micro- and macroadenomas. PATIENTS AND METHODS Forty consecutive patients with proven Cushing's disease (28 microadenomas, 12 macroadenomas [diameter: 10-25 mm], 3 patients with no visible adenoma at MRI) underwent transsphenoidal surgery (TSS) assisted by neuronavigation in our center between 1996 and 2007. The diagnosis was made using standard endocrinological criteria including bilateral inferior petrosal sinus sampling (BIPSS) with CRH stimulation in all patients with discordant or equivocal biochemical and radiological testing. Morning serum cortisol was measured during the first week postoperatively, and a complete endocrine evaluation was made in all patients at 6-8 weeks. Remission at follow-up was defined as a normal postoperative 24-h urinary free cortisol (UFC) or continued need for glucocorticoid hormone replacement after TSS. RESULTS Overall, 32/40 patients (80%) were in remission after one or more TSS. Interestingly, a very good remission rate (92%) was observed in the subset of macroadenomas, similar to that found in the group of microadenomas (84%, NS), while no post-surgical remission was observed in the 3 patients with no visible adenoma at MRI (p<0.01). Of the 8 patients not in remission after repeated TSS surgery, 3 underwent radiation therapy and three had bilateral adrenalectomy, allowing remission of their hypercortisolism. There was minor morbidity and no death. CONCLUSION While our overall results are in accordance with other published series, we show here that ACTH-secreting pituitary macroadenomas are usually not associated with a bad outcome, in contrast with patients with no visible adenoma at preoperative MRI.

Abstract
It has been suggested that the patients with Cushing's disease secondary to pituitary macroadenomas (>10 mm) have higher basal adrenocorticotropic hormone (ACTH) levels, which are less suppressible on high-dose dexamethasone suppression tests (HDDST). We compared the clinical and biochemical characteristics of patients with macroadenomas (N=7) and microadenomas (N=23) who were diagnosed at Samsung Medical Center in Korea between 1996 and 2006. Basal morning plasma ACTH levels were 101.5+/-23.2 pg/mL for macroadenoma patients and 83.6+/-11.1 pg/mL for microadenoma patients (mean+/-SEMs) (p=0.44). Morning serum cortisol levels were 26.8+/-3.2 microg/dL for macroadenoma patients and 29.5+/-2.9 microg/dL for microadenoma patients (p=0.77). The proportion of patients who showed suppressibility on HDDST was almost identical in the two groups (71.4% [5/7] for macroadenoma patients vs. 72.7% [16/22] for microadenoma patients, p=1.00). Furthermore, the remission rate with trans-sphenoidal surgery was similar between the two groups (100% [5/5] for macroadenoma patients vs. 73.3% [11/15] for microadenoma patients, p=0.53). Thus, tumor size is not a major determinant of hormone secretion or clinical outcomes in patients with Cushing's disease.

Abstract
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.

Abstract
OBJECTIVES The aim of this paper was to demonstrate the long-term results following microsurgery in a single surgeon's continuous series of patients with Cushing disease (CD), to assess the influence of changes in surgical procedures, and to compare the results with those of other treatment modalities. In particular, preoperative diagnosis, tumor size, results of histological examination, and complications were considered. METHODS Between 1971 and 2004, 426 patients suffering from newly diagnosed CD underwent primary surgery. Pre-operative measures included clinical examination, endocrinological workup (testing of the hypothalamic-pituitary-adrenal axis, and 2- and 8-mg dexamethasone overnight suppression tests), sellar imaging (polytomography, computed tomography, and magnetic resonance [MR] imaging), and in patients with negative results on imaging studies, inferior petrosal sinus sampling. Follow-up examinations consisting of endocrinological workup, and imaging took place 1 week and 3 months after surgery and then at yearly intervals. RESULTS During microsurgery as first treatment, the adenoma finding rate was 86.6%. After selective adenomectomy, the remission rate was 75.9%, and this rate showed no improvement over the years. The best results were achieved in microadenomas confirmed on MR imaging or histopathological investigation. The recurrence rate (15%) and the complication rate (5.9%) declined over the years. If no adenoma was found, exploration of the sella turcica was performed in 45.6%, hypophysectomy in 3.5%, and hemihypophysectomy in 50.9% of these patients, leading to an early remission in 37.9%. In case of persistence or recurrence, further treatment (repeated operation, adrenalectomy, radio-therapy, or medical treatment) was used to control the disease. CONCLUSIONS Microsurgery remains the treatment of first choice in CD, even though no improvement in remission rates was observed over the years, because complication or remission rates for other treatment options are comparable or worse.

Abstract
Subclinical Cushing's disease (SCD) is characterized by lack of clinically evident Cushingoid features, despite abnormal hypersecretion of ACTH. Nearly half the cases of SCD are due to macroadenomas, and in the majority of them, ACTH secretion is not inhibited even by high-dose dexamethasone. Impaired glucocorticoid (GC) action may be correlated with the proliferation and development of pituitary macroadenomas causing SCD. In this study, immunohistochemical analysis of the resected tumors were performed to evaluate the expression of 11beta-hydroxysteroid dehydrogenase type 2 (11betaHSD2) and glucocorticoid receptor (GR) in pituitary tissues obtained from two SCD (macroadenomas), eight Cushing's disease (CD) (microadenomas), nine acromegaly, and nine normal pituitary (NP). Scattered 11betaHSD2-immunopositive cells were detected in all NP tissues, but its immunoreactivity was totally absent in any tumorous tissues except two CD. Scattered GR-immunopositive cells were also detected and GR immunostaining was restricted to the cytosol in NP tissue. In contrast, GR-immunopositive cells were abundantly present and GR immunostaining was restricted to the nucleus in all the tumorous tissues. There were marked differences in both expression levels and localization between NP tissues and all the tumors. There may be a mechanism other than that via 11betaHSD2 for causes of impaired negative feedback action by GC in SCD and CD, but results of our present study suggest that impaired GC action may be involved, at least in part, in tumorigenesis of SCD and CD.

Abstract
Cushing's disease is a serious endocrinopathy that, if left untreated, is associated with significant morbidity and mortality rates. After diagnostic confirmation of Cushing's disease has been made, transsphenoidal adenomectomy is the treatment of choice. When a transsphenoidal adenomectomy is performed at experienced transsphenoidal surgery centers, long-term remission rates average 80% overall, surgical morbidity is low, and the mortality rate is typically less than 1%. In patients with well-defined noninvasive microadenomas, the long-term remission rate averages 90%. For patients in whom primary surgery fails, treatment options such as bilateral adrenalectomy, stereotactic radiotherapy or radiosurgery, total hypophysectomy, or adrenolytic medical therapy need to be carefully considered, ideally in a multidisciplinary setting. The management of Nelson's Syndrome often requires both transsphenoidal surgery and radio-therapy to gain disease control.

Abstract
Cushing disease is considered an aggressive pituitary endocrinopathy because of the devastating effects from untreated hypercortisolemia. Although they are histologically benign, these adrenocorticotropic hormone (ACTH)-secreting pituitary tumors are associated with significant morbidity and premature death. Currently, transsphenoidal surgery is the primary treatment of Cushing disease associated with an ACTH-secreting pituitary tumor, resulting in remission rates ranging from about 50 to 90%. Some patients, however, will not achieve sustained remission after transsphenoidal surgery and can exhibit persistent or recurrent Cushing disease that requires multimodal treatment to achieve remission. In these patients, options for treatment include repeat transsphenoidal resection, radiation therapy (including conventional fractionated radiation therapy and stereotactic radiosurgery), and medical therapy. Despite undergoing multiple treatment modalities, some patients may ultimately require bilateral adrenalectomy for definitive treatment to eliminate hypercortisolemia associated with Cushing disease. In this article, the authors review the treatment options for patients who have persistent or recurrent Cushing disease after unsuccessful transsphenoidal surgery. The indications, current results reported in the literature, and complications of each treatment modality are discussed.

Abstract
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
Object
The aim of this study was to determine prognostic factors for outcome after transsphenoidal hypophysectomy in dogs with pituitary-dependent hyperadrenocorticism (PDH).
Methods
One veterinary neurosurgeon performed transsphenoidal hypophysectomies in 181 dogs with PDH over a 12-year period. Survival analysis was performed with the Kaplan–Meier method. Prognostic factors were analyzed with the univariate Cox proportional hazard analysis followed by stepwise multivariate analysis. The log-rank test was used to assess disease-free fractions in three groups categorized according to early postoperative urinary corticoid/creatinine (C/C) ratios.
Results
Multivariate analysis revealed that old age, large pituitary size, and high preoperative concentrations of plasma adrenocorticotropic hormone were associated with an increased risk of PDH-related death. In addition, large pituitary size, thick sphenoid bone, high C/C ratio, and high concentration of plasma α-melanocyte–stimulating hormone (α-MSH) before surgery were associated with an increased risk of disease recurrence in the dogs that went into remission after hypophysectomy. Disease-free fractions were significantly higher in dogs with postoperative urinary C/C ratios in the lower normal range (< 5 × 10−6) than in dogs with postoperative C/C ratios in the upper normal range (5–10 × 10−6).
Conclusions
The results of this study indicate that pituitary size, sphenoid bone thickness, plasma α-MSH concentration, and preoperative level of urinary cortisol excretion are predictors of long-term remission after transsphenoidal hypophysectomy for PDH in dogs. Urinary C/C ratios measured 6 to 10 weeks after surgery can be used as a guide for predicting the risk of tumor recurrence.

Abstract
Object
Transsphenoidal pituitary surgery is the primary therapy for Cushing disease because of its potential to produce lasting remission without the need for long-term drug or hormone replacement therapy. The authors evaluated the current role of pure endoscopic endonasal pituitary surgery in the treatment of Cushing disease.
Methods
Twenty-five patients underwent pure endoscopic surgery for confirmed Cushing disease. Thirteen patients had microadenomas and seven had macroadenomas; magnetic resonance images obtained in five patients were only suspicious or nondiagnostic, and thus they underwent inferior petrosal sinus sampling. Two patients had evidence of cavernous sinus involvement. Final histological results were consistent with adrenocorticotropin hormone (ACTH)–secreting adenoma in 20 patients.
Results
Twenty patients (80%) had clinical remission and laboratory confirmation of hypocortisolemia (serum cortisol < 100 nmol/L requiring substitution therapy), suppression to low-dose dexamethasone, and normal 24-hour urinary free cortisol. The median follow-up period was 17 months (range 3–32 months). There was no recurrence at the time of the last follow-up. Three patients presented with new anterior pituitary deficiency, but no one had permanent diabetes insipidus. In one patient a cerebrospinal fluid leak developed but later resolved following lumbar drainage. Treatment failure was attributable to involvement of the cavernous sinus in two patients, incomplete tumor removal in one, negative exploration in one, and nodular corticotroph hyperplasia of the pituitary gland in one.
Conclusions
Early results indicated that endoscopic endonasal surgery is a safe and effective treatment for ACTH-producing adenomas. The rate of remission in this study is comparable to those in previous series, and the rate of major postoperative complications is extremely low. Further studies with a larger number of patients and longer follow-ups are required to determine whether this more minimally invasive pure endoscopic approach should become the standard of care for the surgical treatment of Cushing disease.

Abstract
PURPOSE OF REVIEW Adenectomy via transsphenoidal surgery is considered the treatment of choice for Cushing's disease. It is successful in about 80% of patients in the hands of an experienced surgeon. When transsphenoidal surgery fails or is contraindicated, a second-line treatment must be chosen. The review focuses on second-line treatment options. RECENT FINDINGS Repeat pituitary surgery results in the cure of Cushing's disease in about 50% of cases. Bilateral adrenalectomy results in resolution of hypercortisolemia in almost all patients, but leaves the patient glucocorticoid and mineralocorticoid deficient. Nelson's syndrome, depending on the definition, occurs in up to 35% of these patients. Irradiation of the residual pituitary tumor typically takes several years before the full effect is realized; it can cause panhypopituitarism. Finally, pharmacologic treatment of persistent hypercortisolemia can be effective, but is often associated with untoward side effects. These side effects are a powerful deterrent to its use. Several new pharmacologic agents are being studied and show some promise. SUMMARY Each of the second-line treatments for Cushing's disease currently available can be effective at treating hypercortisolism, but each has significant limitations. New pharmacologic agents may soon offer some very exciting treatment options.

Abstract
Cushing'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.

Abstract
AIM To study the value of early (24 h) post-operative ACTH and serum cortisol as predictors of remission after transsphenoidal surgery in Cushing's disease. METHODS We prospectively studied 44 patients who underwent transsphenoidal surgery for Cushing's disease between 1997 and 2005. The mean follow-up period of patients after surgery was 49 months (19-102 months). The predictive value of clinical characteristics, pre-operative hormonal studies, radiological, surgical and histological findings, and post-operative hormonal studies were analysed. For the post-operative hormonal study plasma ACTH and serum cortisol were determined at 8.00 a.m. the day after surgery. RESULTS After surgery, Cushing's disease remitted in 39 patients (89%) and persisted in 5 patients (11%). Three patients relapsed during the follow-up period. Only three study variables were predictive of persistence of Cushing's disease after surgery: the non identification of the adenoma in histology (an adenoma was found in 87% of the patients in remission, and in 20% of treatment failures, p = 0.01), the early post-operative plasma ACTH (patients in remission: 2 pmol/L (1.1-10.8 pmol/L), treatment failures: 8.2 pmol/L (1.1-12 pmol/L), p = 0.019), and the early post-operative serum cortisol (patients in remission: 128.4 nmol/L (27.6-4644 nmol/L), treatment failures: 797 nmol/L (606-1037 nmol/L), p = 0.003). ROC curves indicated that plasma ACTH < or = 7.55 pmol/L distinguished patients in remission from treatment failures with 80% sensitivity and 97.4% specificity, and serum cortisol < or = 585 nmol/L with 100% sensitivity and 90% specificity. CONCLUSIONS Twenty-four hours after transsesphenoidal surgery for Cushing's disease, and without glucocorticoids replacement, patients with serum cortisol concentrations higher than 585 nmol/L, and/or plasma ACTH higher than 7.55 pmol/L, and/or those in which an adenoma is not identified in the histological study, have a high risk of treatment failure.
