CUSHING'S syndrome ,FRAILTY ,TREATMENT effectiveness - Abstract
This article, published in the Journal of Neurological Surgery, examines the impact of frailty on surgical outcomes in patients with Cushing's disease (CD). The study analyzed data from the Registry of Adenomas of the Pituitary and Related Disorders (RAPID) and found that mild frailty independently predicted outcomes after transsphenoidal surgery for CD. Mildly frail patients had longer hospital stays and were more likely to be discharged to skilled nursing facilities. The study suggests that assessing frailty could be useful for preoperative risk stratification and prognostication in CD patients. [Extracted from the article]

CUSHING'S syndrome ,PATIENT readmissions ,PROPORTIONAL hazards models ,SURGEONS - Abstract
This article discusses the issue of unplanned hospital readmissions following trans-sphenoidal surgery for Cushing's disease. The study analyzed data from a multi-institutional database of patients who underwent this surgery between 2003 and 2023. The results showed that 10.3% of patients experienced unplanned readmissions, with the most common reasons being hyponatremia, CSF leak evaluation, headache/nausea, and epistaxis. The study also found that an increased number of chronic medical conditions and the need for a return to surgery were associated with a higher chance of unplanned readmission. The authors suggest strategies to mitigate these readmissions, such as fluid restriction and optimizing chronic medical conditions. [Extracted from the article]

CUSHING'S syndrome ,DISEASE remission ,PROGRESSION-free survival - Abstract
This article, published in the Journal of Neurological Surgery, explores the factors that contribute to the recurrence of Cushing's disease (CD) after transsphenoidal surgery. The study analyzed data from the Registry of Adenomas of the Pituitary and Related Disorders (RAPID) database, which included 383 CD patients. The results showed that patients who experienced recurrence had a longer postoperative hospital stay, larger tumor volumes, and a higher rate of failed prior treatment. Younger age and the absence of cavernous sinus invasion were identified as potential protective factors against recurrence. The findings suggest that early detection and treatment of tumors may improve outcomes for CD patients. [Extracted from the article]

Introduction Wide variations exist in the management of craniopharyngiomas, including pituitary stalk preservation/sacrifice. This study examines the practice patterns over 16 years using the endoscopic endonasal approach for the resection of craniopharyngiomas and it examines the effects of stalk preservation. Methods Retrospective analysis was conducted for 66 patients who underwent endoscopic transsphenoidal surgery for resection of craniopharyngiomas. Patients were stratified into three epochs: 2005 to 2009 (N = 20), 2010 to 2015 (N = 23), and 2016 to 2020 (N = 20), to examine the evolution of surgical outcomes. Subgroup analysis between stalk preservation/stalk sacrifice was conducted for rate of gross total resection, anterior pituitary function preservation, and development of new permanent diabetes insipidus. Results Gross total resection rates across the first, second, and third epochs were 20, 65, and 52%, respectively (p = 0.042). Stalk preservation across epochs were 100, 5.9, and 52.6% (p = 0.0001). New permanent diabetes insipidus did not significantly change across epochs (37.5, 68.4, 71.4%; p = 0.078). Preservation of normal endocrine function across epochs was 25, 0, and 23.8%; (p = 0.001). Postoperative cerebrospinal fluid (CSF) leaks significantly decreased over time (40, 4.5, and 0%; [ p = 0.0001]). Stalk preservation group retained higher normal endocrine function (40.9 vs. 0%; p = 0.001) and less normal-preoperative to postoperative panhypopituitarism (18.4 vs. 56%; p = 0.001). Stalk sacrifice group achieved higher GTR (70.8 vs. 28%, p = 0.005). At last follow-up, there was no difference in recurrence/progression rates between the two groups. Conclusion There is a continuous evolution in the management of craniopharyngiomas. Gross total resection, higher rates of pituitary stalk and hormonal preservation, and low rates of postoperative CSF leak can be achieved with increased surgical experience. [ABSTRACT FROM AUTHOR]

Introduction In pituitary adenomas (PAs), the use of postoperative steroid supplementation remains controversial, as it reduces peritumoral edema and sinonasal complaints but disrupts the detection of adrenal insufficiency (AI). It is unclear whether postoperative cortisol supplementation has a measurable effect on improving outcomes in patients with pituitary adenoma undergoing endoscopic transsphenoidal surgery (ETS). The objective of the study was to evaluate a postoperative steroid treatment protocol on various surgical outcomes in patients with PA undergoing ETS. Methods A retrospective cohort study was performed for patients undergoing ETS from 2005 to 2020 for PA at a single tertiary academic center. Patients were divided into two groups: those managed by a routine postoperative glucocorticoid supplementation protocol (steroid protocol) and those who received supplementation based on postoperative cortisol laboratory assessment (steroid sparing protocol). Management was otherwise the same between groups. Evaluation of length of stay (LOS), sinonasal outcomes, 30-day readmission, and perioperative complications, including AI, were performed. Results Among 535 patients, 21% (n = 111) received postoperative steroids, while the remainder (n = 424) did not. There were no differences in mean LOS (3 vs. 3 days, p = 0.72), sinonasal complaints (27 vs. 19%, p = 0.12), 30-day readmission (5% vs. 5%, p = 0.44), and perioperative complications (5 vs. 5%, p = 0.79) between both the groups. A multivariate model supported that both groups were comparable in predicting LOS, 30-day readmission, and complications. No reduction in readmission for AI was seen. Conclusion Routine administration of postoperative glucocorticoids did not significantly improve patient outcomes in patients with PA who underwent ETS. [ABSTRACT FROM AUTHOR]

Introduction Pituitary adenomas (PAs) are one of the most common types of intracranial neoplasm with increased incidence in elderly patients. The outcomes of endoscopic transsphenoidal surgery (ETS) specifically on elderly patients remain unclear. Methods We performed a retrospective cohort study to compare elderly patients (age ≥65 years) with nonelderly patients (age <65 years) who underwent ETS for PA from January 2005 to December 2020. Surgical outcomes, including extent of resection, complication profile, length of stay, and endocrinopathy rates, were compared between elderly and nonelderly patients. Results A total of 690 patients were included, with 197 (29%) being elderly patients. Elderly patients showed higher rates of hypertension (p < 0.05), myocardial infarction (p < 0.01), and atrial fibrillation (p = 0.01) but not other comorbidities. Elderly patients also had more frequent optic nerve involvement (72 vs. 61% of cases, p = 0.01). Tumor characteristics and other patient variables were otherwise similar between younger and elderly patients. Postoperative cerebrospinal fluid (CSF) leaks (2 vs. 2%, p = 0.8), 30-day readmission, reoperation, postoperative complications, and postoperative endocrinopathies were similar between younger and older patients. Subdividing patients into age <65, 65 to 79, and >80 years also did not demonstrate a worsening of surgical outcomes with age. Conclusion For well-selected elderly patients in experienced endoscopic skull base centers, good surgical outcomes similarly to younger patients may be achieved. [ABSTRACT FROM AUTHOR]

Telemedicine use skyrocketed in March 2020 on implementation of shelter-in-place measures owing to the coronavirus disease 2019 (COVID-19) pandemic. Within the past year, shelter-in-place measures were lifted and the COVID-19 vaccine was released, resulting in many neurosurgeons returning to in-person outpatient clinics. This study aimed to determine the extent of usage of telemedicine in neurosurgery 1 year into the COVID-19 pandemic. A retrospective cohort study of patients who received neurosurgical care at a single institution from February 1 to April 18 of the years 2020 and 2021 was performed. The inclusion criteria were met by 11,592 patients. During the 2 study periods, 1465 patients underwent surgery, 7083 were seen in clinic via an in-person meeting, and 3044 were assessed via telemedicine. At 1 year after the COVID-19 outbreak, telemedicine usage was at 81.3% of the initial volume on implementation of shelter-in-place measures. In-person outpatient visits increased 40.2% from the early pandemic volume. Among the 4 neurosurgery divisions, telemedicine usage remained high in tumor and functional neurosurgery, significantly increased in vascular neurosurgery, and decreased in spine neurosurgery. Telemedicine use in neurosurgery clinics continues 1 year after the COVID-19 outbreak. Even after the lifting of shelter-in-place measures, many neurosurgeons still use telemedicine, while the operative volume remains stable. Owing to the limited physical examination that can be performed via current telemedicine platforms, telemedicine use in spine neurosurgery is lower than peak use during the early pandemic, while use has remained high among tumor, vascular, and functional neurosurgery.

- Abstract
Background and Objectives: Despite growing interest in how patient frailty affects outcomes (eg, in neuro-oncology), its role after transsphenoidal surgery for Cushing disease (CD) remains unclear. We evaluated the effect of frailty on CD outcomes using the Registry of Adenomas of the Pituitary and Related Disorders (RAPID) data set from a collaboration of US academic pituitary centers., Methods: Data on consecutive surgically treated patients with CD (2011-2023) were compiled using the 11-factor modified frailty index. Patients were classified as fit (score, 0-1), managing well (score, 2-3), and mildly frail (score, 4-5). Univariable and multivariable analyses were conducted to examine outcomes., Results: Data were analyzed for 318 patients (193 fit, 113 managing well, 12 mildly frail). Compared with fit and managing well patients, mildly frail patients were older (mean ± SD 39.7 ± 14.2 and 48.9 ± 12.2 vs 49.4 ± 8.9 years, P < .001) but did not different by sex, race, and other factors. They had significantly longer hospitalizations (3.7 ± 2.0 and 4.5 ± 3.5 vs 5.3 ± 3.5 days, P = .02), even after multivariable analysis (β = 1.01, P = .007) adjusted for known predictors of prolonged hospitalization (age, Knosp grade, surgeon experience, American Society of Anesthesiologists grade, complications, frailty). Patients with mild frailty were more commonly discharged to skilled nursing facilities (0.5% [1/192] and 4.5% [5/112] vs 25% [3/12], P < .001). Most patients underwent gross total resection (84.4% [163/193] and 79.6% [90/113] vs 83% [10/12]). No difference in overall complications was observed; however, venous thromboembolism was more common in mildly frail (8%, 1/12) than in fit (0.5%, 1/193) and managing well (2.7%, 3/113) patients (P = .04). No difference was found in 90-day readmission rates., Conclusion: These results demonstrate that mild frailty predicts CD surgical outcomes and may inform preoperative risk stratification. Frailty-influenced outcomes other than age and tumor characteristics may be useful for prognostication. Future studies can help identify strategies to reduce disease burden for frail patients with hypercortisolemia., (Copyright © Congress of Neurological Surgeons 2024. All rights reserved.)

- Abstract
Background and Objective: Cushing disease (CD) affects mortality and quality of life along with limited long-term remission, underscoring the need to better identify recurrence risk. The identification of surgical or imaging predictors for CD remission after transsphenoidal surgery has yielded some inconsistent results and has been limited by single-center, single-surgeon, or meta-analyses studies. We sought to evaluate the multicenter Registry of Adenomas of the Pituitary and Related Disorders (RAPID) database of academic US pituitary centers to assess whether robust nonhormonal recurrence predictors could be elucidated., Methods: Patients with treated CD from 2011 to 2023 were included. The perioperative and long-term characteristics of CD patients with and without recurrence were assessed using univariable and multivariable analyses., Results: Of 383 patients with CD from 26 surgeons achieving postoperative remission, 288 (75.2%) maintained remission at last follow-up while 95 (24.8%) showed recurrence (median time to recurrence 9.99 ± 1.34 years). Patients with recurrence required longer postoperative hospital stays (5 ± 3 vs 4 ± 2 days, P = .002), had larger average tumor volumes (1.76 ± 2.53 cm3 vs 0.49 ± 1.17 cm3, P = .0001), and more often previously failed prior treatment (31.1% vs 14.9%, P = .001) mostly being prior surgery. Multivariable hazard prediction models for tumor recurrence found younger age (odds ratio [OR] = 0.95, P = .002) and Knosp grade of 0 (OR = 0.09, reference Knosp grade 4, P = .03) to be protective against recurrence. Comparison of Knosp grade 0 to 2 vs 3 to 4 showed that lower grades had reduced risk of recurrence (OR = 0.27, P = .04). Other factors such as length of stay, surgeon experience, prior tumor treatment, and Knosp grades 1, 2, or 3 failed to reach levels of statistical significance in multivariable analysis., Conclusion: This multicenter study centers suggests that the strongest predictors of recurrence include tumor size/invasion and age. This insight can help with patient counseling and prognostication. Long-term follow-up is necessary for patients, and early treatment of small tumors may improve outcomes., (Copyright © Congress of Neurological Surgeons 2024. All rights reserved.)

- Abstract
Background and Objectives: To address the lack of a multicenter pituitary surgery research consortium in the United States, we established the Registry of Adenomas of the Pituitary and Related Disorders (RAPID). The goals of RAPID are to examine surgical outcomes, improve patient care, disseminate best practices, and facilitate multicenter surgery research at scale. Our initial focus is Cushing disease (CD). This study aims to describe the current RAPID patient cohort, explore surgical outcomes, and lay the foundation for future studies addressing the limitations of previous studies., Methods: Prospectively and retrospectively obtained data from participating sites were aggregated using a cloud-based registry and analyzed retrospectively. Standard preoperative variables and outcome measures included length of stay, unplanned readmission, and remission., Results: By July 2023, 528 patients with CD had been treated by 26 neurosurgeons with varying levels of experience at 9 academic pituitary centers. No surgeon treated more than 81 of 528 (15.3%) patients. The mean ± SD patient age was 43.8 ± 13.9 years, and most patients were female (82.2%, 433/527). The mean tumor diameter was 0.8 ± 2.7 cm. Most patients (76.6%, 354/462) had no prior treatment. The most common pathology was corticotroph tumor (76.8%, 381/496). The mean length of stay was 3.8 ± 2.5 days. The most common discharge destination was home (97.2%, 513/528). Two patients (0.4%, 2/528) died perioperatively. A total of 57 patients (11.0%, 57/519) required an unplanned hospital readmission within 90 days of surgery. The median actuarial disease-free survival after index surgery was 8.5 years., Conclusion: This study examined an evolving multicenter collaboration on patient outcomes after surgery for CD. Our results provide novel insights on surgical outcomes not possible in prior single-center studies or with national administrative data sets. This collaboration will power future studies to better advance the standard of care for patients with CD., (Copyright © Congress of Neurological Surgeons 2024. All rights reserved.)

- Abstract
Background Chordomas are histologically benign but locally aggressive tumors with a high propensity to recur. Our case highlights the importance of long-term vigilance in patients who have undergone chordoma resection. Case Report We report the case of a 47-year-old man with a cervical chordoma who developed multiple musculoskeletal ectopic recurrences in the left supraclavicular region, the proximal right bicep, and the left submandibular region without recurrence in the primary tumor site. Primary tumor resection was achieved via a combination of surgery, adjuvant radiation therapy, and imatinib. All recurrences were successfully resected and confirmed via pathology to be ectopic chordoma. Discussion Ectopic recurrence of cervical chordoma is rare and lung is the most common site of distant spread. Chordoma recurrence in skeletal muscle is particularly rare, with only 10 cases described in the literature. A plausible mechanism of distant metastatic disease in chordoma patients suggests that tumor cells escape the surgical tract via a combination of cytokine release, vasodilation, and microtrauma induced during resection. Conclusion Cervical chordoma with ectopic recurrence in skeletal muscle has not been previously described in the literature. Skull base surgeons should be aware of the phenomenon of chordoma ectopic recurrence in the absence of local recurrence., Competing Interests: Conflict of Interest J.J.E. received royalties from Mizuho., (The Author(s).

- Abstract
Introduction: Dural tails are thickened contrast-enhancing portions of dura associated with some meningiomas. Prior studies have demonstrated the presence of tumor cells within the dural tail, however their inclusion in radiation treatment fields remains controversial. We evaluated the role of including the dural tail when treating a meningioma with stereotactic radiation and the impact on tumor recurrence., Methods: This is a retrospective, single-institution, cohort study of patients with intracranial World Health Organization (WHO) grade 1 meningioma and identified dural tail who were treated with stereotactic radiosurgery (SRS) or fractionated stereotactic radiotherapy (FSRT) from January 2012 to December 2018. SRS and FSRT subgroups were categorized based on coverage or non-coverage of the dural tail by the radiation fields, as determined independently by a radiation oncologist and a neurosurgeon. Demographics, tumor characteristics, radiation plans, and outcomes were evaluated. High grade tumors were analyzed separately., Results: A total of 187 WHO grade 1 tumors from 177 patients were included in the study (median age: 62 years, median follow-up: 40 months, 78.1% female) with 104 receiving SRS and 83 receiving FSRT. The dural tail was covered in 141 (75.4%) of treatment plans. There was no difference in recurrence rates (RR) or time to recurrence (TTR) between non-coverage or coverage of dural tails (RR: 2.2% vs 3.5%, P = 1.0; TTR: 34 vs 36 months, P = 1.00). There was no difference in the rate of radiation side effects between dural tail coverage or non-coverage groups. These associations remained stable when SRS and FSRT subgroups were considered separately, as well as in a high grade cohort of 16 tumors., Conclusion: Inclusion of the dural tail in the SRS or FSRT volumes for meningioma treatment does not seem to reduce recurrence rate. Improved understanding of dural tail pathophysiology, tumor grade, tumor spread, and radiation response is needed to better predict the response of meningiomas to radiotherapy., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (© 2022 Piper, Yu, Taghvaei, Fernandez, Mouchtouris, Smit, Yudkoff, Collopy, Reyes, Lavergne, Karsy, Prashant, Shi and Evans.)

- Abstract
Background: The proximity of craniopharyngiomas (CPs) to critical neurovascular structures can lead to a host of neurologic and endocrine complications that lead to difficulty with surgical management. In this review, we examine the molecular and genetic markers implicated in CP, their involvement in tumorigenic pathways, and their impact on CP prognosis and treatment., Methods: We undertook a focused review of relevant articles, clinical trials, and molecular summaries regarding CP., Results: Genetic and immunological markers show variable expression in different types of CP. BRAF is implicated in tumorigenesis in papillary CP (pCP), whereas CTNNB1 and EGFR are often overexpressed in adamantinomatous CP (aCP) and VEGF is overexpressed in aCP and recurrent CP. Targeted treatment modalities inhibiting these pathways can shrink or halt progression of CP. In addition, EGFR inhibitors may sensitize tumors to radiation therapy. These drugs show promise in medical management and neoadjuvant therapy for CP. Immunotherapy, including anti-interleukin-6 (IL-6) drugs and interferon treatment, are also effective in managing tumor growth. Ongoing clinical trials in CP are limited but are testing BRAF/MET inhibitors and IL-6 monoclonal antibodies., Conclusions: Genetic and immunological markers show variable expression in different subtypes of CP. Several current molecular treatments have shown some success in the management of this disease. Additional clinical trials and targeted therapies will be important to improve CP patient outcomes., Competing Interests: The authors declare no conflict of interest.

- Abstract
Objective: While multiple studies have evaluated the length of stay after endonasal transsphenoidal surgery (ETS) for pituitary adenoma, the potential for early discharge on postoperative day 1 (POD 1) remains unclear. The authors compared patients discharged on POD 1 with patients discharged on POD > 1 to better characterize factors that facilitate early discharge after ETS., Methods: A retrospective chart review was performed for patients undergoing ETS for pituitary adenoma at a single tertiary care academic center from February 2005 to February 2020. Discharge on POD 1 was defined as a discharge within 24 hours of surgery., Results: A total of 726 patients (mean age 55 years, 52% male) were identified, of whom 178 (24.5%) patients were discharged on POD 1. These patients were more likely to have pituitary incidentaloma (p = 0.001), require dural substitutes and DuraSeal (p = 0.0001), have fewer intraoperative CSF leaks (p = 0.02), and have lower postoperative complication rates (p = 0.006) compared with patients discharged on POD > 1. POD 1 patients also showed higher rates of macroadenomas (96.1% vs 91.4%, p = 0.03) and lower rates of functional tumors (p = 0.02). POD > 1 patients were more likely to have readmission within 30 days (p = 0.002), readmission after 30 days (p = 0.0001), nasal synechiae on follow-up (p = 0.003), diabetes insipidus (DI; 1.7% vs 9.8%, p = 0.0001), postoperative hypocortisolism (21.8% vs 12.1%, p = 0.01), and postoperative steroid usage (44.6% vs 59.7%, p = 0.003). The number of patients discharged on POD 1 significantly increased during each subsequent time epoch: 2005-2010, 2011-2015, and 2016-2020 (p = 0.0001). On multivariate analysis, DI (OR 7.02, 95% CI 2.01-24.57; p = 0.002) and intraoperative leak (OR 2.02, 95% CI 1.25-3.28; p = 0.004) were associated with increased risk for POD > 1 discharge, while operation epoch (OR 0.46, 95% CI 0.3-0.71; p = 0.0001) was associated with POD 1 discharge., Conclusions: This study demonstrates that discharge on POD 1 after ETS for pituitary adenomas was safe and feasible and without increased risk of 30-day readmission. On multivariate analysis, surgical epoch was associated with decreased risk of prolonged length of stay, while factors associated with increased risk of prolonged length of stay included DI and intraoperative CSF leak. These findings may help in selecting patients who are deemed reasonable for safe, early discharge after pituitary adenoma resection.

- Abstract
Introduction In pituitary adenomas (PAs), the use of postoperative steroid supplementation remains controversial, as it reduces peritumoral edema and sinonasal complaints but disrupts the detection of adrenal insufficiency (AI). It is unclear whether postoperative cortisol supplementation has a measurable effect on improving outcomes in patients with pituitary adenoma undergoing endoscopic transsphenoidal surgery (ETS). The objective of the study was to evaluate a postoperative steroid treatment protocol on various surgical outcomes in patients with PA undergoing ETS. Methods A retrospective cohort study was performed for patients undergoing ETS from 2005 to 2020 for PA at a single tertiary academic center. Patients were divided into two groups: those managed by a routine postoperative glucocorticoid supplementation protocol (steroid protocol) and those who received supplementation based on postoperative cortisol laboratory assessment (steroid sparing protocol). Management was otherwise the same between groups. Evaluation of length of stay (LOS), sinonasal outcomes, 30-day readmission, and perioperative complications, including AI, were performed. Results Among 535 patients, 21% ( n = 111) received postoperative steroids, while the remainder ( n = 424) did not. There were no differences in mean LOS (3 vs. 3 days, p = 0.72), sinonasal complaints (27 vs. 19%, p = 0.12), 30-day readmission (5% vs. 5%, p = 0.44), and perioperative complications (5 vs. 5%, p = 0.79) between both the groups. A multivariate model supported that both groups were comparable in predicting LOS, 30-day readmission, and complications. No reduction in readmission for AI was seen. Conclusion Routine administration of postoperative glucocorticoids did not significantly improve patient outcomes in patients with PA who underwent ETS., Competing Interests: Conflict of Interest None declared., (Thieme.
