Medium and Long-Term Data from a Series of 96 Endoscopic Transsphenoidal Surgeries for Cushing Disease. J Korean Neurosurg Soc 2024; 67:237-248. [PMID: 38449382 PMCID: PMC10924914 DOI: 10.3340/jkns.2023.0100] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 08/06/2023] [Accepted: 11/06/2023] [Indexed: 03/08/2024] Open
Abstract
OBJECTIVE Postoperative data on Cushing's disease (CD) are equivocal in the literature. These discrepancies may be attributed to different series with different criteria for remission and variable follow-up durations. Additional data from experienced centers may address these discrepancies. In this study, we present the results obtained from 96 endoscopic transsphenoidal surgeries (ETSSs) for CD conducted in a well-experienced center. METHODS Pre- and postoperative data of 96 ETSS in 87 patients with CD were included. All cases were handled by the same neurosurgical team between 2014 and 2022. We obtained data on remission status 3-6 months postoperatively (medium-term) and during the latest follow-up (long-term). Additionally, magnetic resonance imaging (MRI) and pathology results were obtained for each case. RESULTS The mean follow-up duration was 39.5±3.2 months. Medium and long-term remission rates were 77% and 82%, respectively. When only first-time operations were considered, the medium- and long-term remission rates were 78% and 82%, respectively. The recurrence rate in this series was 2.5%. Patients who showed remission between 3-6 months had higher longterm remission rates than did those without initial remission. Tumors >2 cm and extended tumor invasion of the cavernous sinus (Knosp 4) were associated with lower postoperative remission rates. CONCLUSION Adenoma size and the presence/absence of cavernous sinus invasion on preopera-tive MRI may predict long-term postoperative remission. A tumor size of 2 cm may be a supporting criterion for predicting remission in Knosp 4 tumors. Further studies with larger patient populations are necessary to support this finding.

Abstract
Background Cushing's disease (CD) poses significant challenges in its treatment due to the lack of reliable biomarkers for predicting tumor localization or postoperative clinical outcomes. Sphingosine-1-phosphate (S1P) has been shown to increase cortisol biosynthesis and is regulated by adrenocorticotropic hormone (ACTH). Methods We employed bilateral inferior petrosal sinus sampling (BIPSS), which is considered the gold standard for diagnosing pituitary sources of CD, to obtain blood samples and explore the clinical predictive value of the S1P concentration ratio in determining tumor laterality and postoperative remission. We evaluated 50 samples from 25 patients who underwent BIPSS to measure S1P levels in the inferior petrosal sinuses bilaterally. Results Serum S1P levels in patients with CD were significantly higher on the adenoma side of the inferior petrosal sinus than on the nonadenoma side (397.7 ± 15.4 vs. 261.9 ± 14.88; P < 0.05). The accuracy of diagnosing tumor laterality with the interpetrosal S1P and ACTH ratios and the combination of the two was 64%, 56% and 73%, respectively. The receiver operating characteristic curve analysis revealed that the combination of interpetrosal S1P and ACTH ratios, as a predictor of tumor laterality, exhibited a sensitivity of 81.82% and a specificity of 75%, with an area under the curve value of 84.09%. Moreover, we observed that a high interpetrosal S1P ratio was associated with nonremission after surgery. Correlation analyses demonstrated that the interpetrosal S1P ratio was associated with preoperative follicle-stimulating hormone (FSH), luteinizing hormone (LH), and postoperative ACTH 8 am levels (P < 0.05). Conclusion Our study demonstrated a significant association between the interpetrosal S1P ratio and tumor laterality, as well as postoperative remission in CD, suggesting that the interpetrosal S1P ratio could serve as a valuable biomarker in clinical practice.

Abstract
Cushing disease (CD) is the main cause of endogenous Cushing syndrome (CS) and is produced by an adrenocorticotropic hormone (ACTH)-producing pituitary adenoma. Its relevance in pediatrics is due to the retardation of both growth and developmental processes because of hypercortisolism. In childhood, the main features of CS are facial changes, rapid or exaggerated weight gain, hirsutism, virilization, and acne. Endogenous hypercortisolism should be established after exogenous CS has been ruled out based on 24-hour urinary free cortisol, midnight serum or salivary cortisol, and dexamethasone suppression test; after that, ACTH dependence should be established. The diagnosis should be confirmed by pathology. The goal of treatment is to normalize cortisol level and reverse the signs and symptoms. Treatment options include surgery, medication, radiotherapy, or combined therapy. CD represents a challenge for physicians owing to its multiple associated conditions involving growth and pubertal development; thus, it is important to achieve an early diagnosis and treatment in order to control hypercortisolism and improve the prognosis. Its rarity in pediatric patients has led physicians to have limited experience in its management. The objective of this narrative review is to summarize the current knowledge about the pathophysiology, diagnosis, and treatment of CD in the pediatric population.

Abstract
OBJECTIVE Transsphenoidal surgery (TSS) is the first-line treatment for patients with Cushing's disease (CD). However, the reported remission rates of patients who received TSS vary widely between different studies, and the predictors of surgical outcomes remain controversial. The present study analyzed the early outcome of TSS in a large population of patients with CD at a single center, and identified potential predictors of initial remission of TSS in patients with CD. METHODS The clinical features and surgical outcomes of CD patients who underwent TSS between 1988 and 2018 at Peking Union Medical College Hospital (PUMCH) were collected and analyzed from their medical records. RESULTS Of the 1604 CD patients who underwent TSS at PUMCH between February 1988 and October 2018, 1106 patients had complete medical data and pathological results. After surgery, the overall postoperative initial remission rate was 72.5, and 27.5% of patients maintained persistent hypercortisolism. The initial remission rate of patients with preoperative noninvasive adenoma based on MRI (77.1%), intraoperative noninvasiveness (72.5%), microadenoma (74.3%), pathological confirmation (76.4%), and first TSS (73.9%) was significantly higher than that in patients with preoperative invasive adenoma (53.0%), intraoperative invasiveness (60.7%), macroadenomas (65.9%), pathologically negative (49.7%), and repeat TSS (56.0%), respectively (all P < 0.05). The initial remission rate in patients with pseudocapsule-based extracapsular resection (88.1%), MRI-visible adenoma (74.2%) was higher than that in patients without pseudocapsule-based extracapsular resection (77.1%), and with MRI-negative results (64.5%), respectively, but did not reach statistical significance (All P > 0.05). Striking, there was no significant differences in initial remission rates between patients who underwent selective adenomectomy and enlarged adenomectomy (P > 0.05). Whereas, the initial remission rates in patients who underwent partial hypophysectomy only was 51.0%, which was much lower than that in patients underwent selective adenomectomy and enlarged adenomectomy (P < 0.05). CONCLUSION The TSS is a safe and effective procedure for the treatment of CD. Whereas, preoperative invasiveness based on MRI, intraoperative invasiveness, macroadenomas pathologically negative, and repeat TSS are related to lower initial remission rates.

Abstract
PURPOSE Hypofractionated stereotactic radiotherapy (HSRT) for refractory Cushing's disease may offer a condensed treatment schedule for patients with large tumors abutting the optic chiasm unsuitable for stereotactic radiosurgery (SRS). To-date only four patients have been treated by HSRT in the published literature. We investigated the feasibility, toxicity, and efficacy of HSRT compared to SRS. METHODS After approval, we retrospectively evaluated patients treated at our institution for refractory Cushing's disease with SRS or HSRT. Study outcomes included biochemical control, time to biochemical control, local control, and late complications. Binary logistic regression and Cox proportional hazards regression evaluated predictors of outcomes. RESULTS Patients treated with SRS (n = 9) and HSRT (n = 9) were enrolled with median follow-up of 3.4 years. Clinicopathologic details were balanced between the cohorts. Local control was 100% in both cohorts. Time to biochemical control was 6.6. and 9.5 months in the SRS and HSRT cohorts, respectively (p = 0.6258). Two patients in each cohort required salvage bilateral adrenalectomy. Late complications including secondary malignancy, radionecrosis, cranial nerve neuropathy, and optic pathway injury were minimal for either cohort. CONCLUSIONS HSRT is an appropriate treatment approach for refractory Cushing's disease, particularly for patients with large tumors abutting the optic apparatus. Prospective studies are needed to validate these findings and identify factors suggesting optimal fractionation approaches.

Abstract
INTRODUCTION Differentiation of normal pituitary from abnormal tumor tissue remains a surgical challenge despite improvements in optical visualization technology for pituitary adenoma (PA) surgery. During neurosurgical procedures for other tumor types, 5-aminolevulinic acid (5-ALA) has become a focus of investigation based on its high specificity in differentiating tumor tissue. However, the role of 5-ALA and other optical fluorescent agents in PA surgery remains less clear. OBJECTIVE To perform a systematic review on the use of various optical fluorescent agents in PA surgery. METHOD Using PRISMA guidelines, a systematic literature review to identify reports describing 5-ALA and other optical agents for fluorescence-guided surgery for PA was performed. Eleven research studies met inclusion criteria and were reviewed. RESULTS In two studies, 5-ALA was not shown to be effective in aiding PA resection using standard neurosurgical endoscopic/microscopic approaches. 5-ALA photodynamic therapy was evaluated in two in-vitro models with inconsistent results. Intraoperative use of indocyanine green (ICG) concluded with varying results, but showed a tendency towards improved differentiation of functional PA. OTL38 showed potential for intraoperative identification of nonfunctioning PA, particularly in tumors with high folate receptor expression. One study reported clinically useful fluorescence following sodium fluorescein administration. CONCLUSION We conclude that selected optical fluorescent agents, including ICG and folate receptors, are most likely to hold promise for clinical use in differentiating PA from normal tissue.

Abstract
RATIONALE Typical pulmonary carcinoid is a kind of low-grade malignancy neuroendocrine tumor. Cushing's syndrome is a very rare clinical feature of typical pulmonary carcinoid caused by hypercorticism. Complete tumor resection is the standard curative treatment for primary typical pulmonary carcinoid. However, our knowledge on the gene level of typical pulmonary carcinoid is limited. PATIENT CONCERNS A 42-year-old man was admitted to our hospital for progressive weight gain within one year. No other obvious symptoms were obsessed in this patient. He was clinical diagnosed with ectopic adrenocorticotropic hormone syndrome through hormonal tests and imaging exams. Positron emission tomography-computed tomography detected a pulmonary nodule localized in the middle lobe of the lung and it is thought to be the ectopic source. INTERVENTION This patient received a pulmonary wedge resection. After the surgery, a genetic sequencing was performed and it reported a mutation (S1240Cfs*21) in the BCOR gene. DIAGNOSIS Postoperative pathology confirmed the diagnosis of ACTH-producing typical pulmonary carcinoid. OUTCOMES The patient had a smooth postoperative course and no recurrence of the tumor was found for 3 years. LESSONS Mutation in BCOR gene is quite common in pulmonary neuroendocrine tumor and it has been proven to play a role in the development of some tumor. We herein first report BCOR gene mutation in Cushing's syndrome secondary to TPC and it may become a promising therapeutic target in the future.

Abstract
Adrenocorticotropin (ACTH) acts via a highly selective receptor that is a member of the melanocortin receptor subfamily of type 1 G protein-coupled receptors. The ACTH receptor, also known as the melanocortin 2 receptor (MC2R), is unusual in that it is absolutely dependent on a small accessory protein, melanocortin receptor accessory protein (MRAP) for cell surface expression and function. ACTH is the only known naturally occurring agonist for this receptor. This lack of redundancy and high degree of ligand specificity suggests that antagonism of this receptor could provide a useful therapeutic aid and a potential investigational tool. Clinical situations in which this could be useful include (1) Cushing's disease and ectopic ACTH syndrome - especially while preparing for definitive treatment of a causative tumor, or in refractory cases, or (2) congenital adrenal hyperplasia - as an adjunct to glucocorticoid replacement. A case for antagonism in other clinical situations in which there is ACTH excess can also be made. In this article, we will explore the scientific and clinical case for an ACTH antagonist, and will review the evidence for existing and recently described peptides and modified peptides in this role.

Abstract
BACKGROUND Cushing's disease is an ACTH-producing pituitary adenoma, and the primary treatment is microscopic or endoscopic transsphenoidal selective adenectomy. The aims of the present study were to evaluate whether the early postoperative S-cortisol level can serve as a prognostic marker for short- and long-term remission, and retrospectively review our own short and long term results after surgery for Cushing's disease. METHODS This single centre, retrospective study consists of 19 consecutive patients with Cushing's disease who underwent transsphenoidal surgery. S-cortisol was measured every 6 h after the operation without any glucocorticoid replacement. We have follow-up on all patients, with a mean follow-up of 68 months. RESULTS At the three-month follow-up, 16 patients (84 %) were in remission; at 12 months, 18 (95 %) were in remission and at the final follow-up (mean 68 months), 13 (68 %) were in remission. Five-years recurrence rate was 26 %. The mean postoperative S-cortisol nadir was significantly lower in the group of patients in remission than in the non-remission group at 3 months, but there was no difference between those in long-term remission compared to those in long-term non-remission. The optimal cut-off value for classifying 3-month remission was 74 nmol/l. CONCLUSION We achieved a 95 % 1-year remission rate with transsphenoidal surgery for Cushing's disease in this series of consecutive patients. However, the 5-year recurrence rate was 26 %, showing the need for regular clinical and biochemical controls in this patient group. The mean postoperative serum-cortisol nadir was significantly lower in patients in remission at 3 months compared to patients not in remission at 3 months, but a low postoperative S-cortisol did not predict long-term remission.

Abstract
PURPOSE OF REVIEW To provide an update on the genes associated with Cushing's syndrome in children, as well as to familiarize the clinician with recent treatment guidelines and outcome data for children with Cushing's syndrome. RECENT FINDINGS The list of genes associated with Cushing's syndrome continues to grow. In addition, treatment for childhood Cushing's syndrome is evolving. As long-term follow-up data on children becomes available, clinicians need to be aware of the issues that require attention. SUMMARY Knowledge of the specific genetic causes of Cushing's syndrome has potential implications for treatment, surveillance, and counseling. Advances in surgical technique, radiation modalities, and medical therapies offer the potential for additional treatment options in Cushing's syndrome. Early identification and management of post-treatment morbidities in children treated for Cushing's syndrome is crucial in order to optimize care.

Abstract
We compared the immunoprofile of pituitary adenomas from Romania and Moldova. One hundred and eighty cases coming from Romania (94 cases, group 1) and Moldova (86 cases, group 2) were assessed by immunohistochemistry regarding all six basic hormones expressed in pituitary adenomas. Specific differences and similarities were found and stated for both groups. In group 1, 70% of cases were pituitary adenomas positive for one hormone, 13% were plurihormonal, while 17% were negative. In group 2, 50,3% of the cases expressed only one hormone and 12,5% were negative for all hormones. The highest difference was observed for plurihormonal adenomas, found in about 37,2% of cases for group 2 (2.86 times higher for group 2 compared with group 1). A higher incidence of GH-secreting adenomas characterized group "1," while group "2" had the highest percent of LH-secreting adenomas, 55% of cases being positive. Triple association was noticed in 4.25% of cases of group 1 and in 8,13% out of total cases, from group 2. Four-hormone association was found only in group 2, noticed in 15,56% of the cases. The present paper highlights strong evidences of a particular and different immunoprofile of pituitary adenomas coming from Romania and Moldova.
