Item Adenoid Cystic Carcinoma (ACC) Infiltrating the Skull Base: A Systematic Review of Clinical Characteristics and Management Strategies(International Institute of Anticancer Research, 2022-09-03) Bin-Alamer, Othman; Haider, Ali S.; Chaudhary, Adhiraj; Balasubramanian, Kishore; Breeding, Tessa; Palmisciano, Paolo; Haider, Maryam; Cohen-Gadol, Aaron A.; El Ahmadieh, Tarek Y.; Yu, Kenny; Neurological Surgery, School of MedicineBackground/aim: To systematically review the patient characteristics and management approaches of adenoid cystic carcinoma (ACC) infiltrating the skull base. Materials and methods: According to PRISMA guidelines, PubMed, Scopus, and Cochrane were searched to retrieve studies reporting management protocols and survival outcomes of patients with skull base ACCs. Patient characteristics, management strategies, and outcomes were investigated. Results: The review encompassed 17 studies involving 171 patients, with a female predominance (57.9%) and a mean age of 49±7.12 years. ACCs mostly infiltrated the paranasal sinus (22.2%), cavernous sinus (8.8%), and nasopharynx (7.1%). Perineural invasion was reported in 6.4% of cases. Facial pain, nasal obstruction, and facial paresthesia were the most common symptoms. Surgical resection (45.6%) was favored over biopsy (12.2%). Employing the free flap technique (4.7%), surgical reconstruction of the bony defect after resection was performed using abdominal and anterior thigh muscle grafts in 1.8% of patients each. As adjuvant management, 22.8% of cases had radiotherapy and 14.6% received chemotherapy. Recurrence of skull base ACCs occurred in 26.9% of cases during a mean follow up-time of 30.8±1.8 months. Conclusion: Skull base ACCs pose a surgical challenge mainly due to their proximity to critical neurovascular structures and aggressive behavior. Surgical resection and radiotherapy are shown to be safe and effective treatment modalities. The dismal prognosis and limited data on non-surgical strategies highlight the need for further evaluation of the current management paradigm and upraising innovative therapies to improve patient mortality and quality of life.Item Adenoid Cystic Carcinoma (ACC) Infiltrating the Skull Base: A Systematic Review of Clinical Characteristics and Management Strategies(IIAR, 2022-09-03) Bin-Alamer, Othman; Haider, Ali S.; Chaudhary, Adhiraj; Balasubramanian, Kishore; Breeding, Tessa; Palmisciano, Paolo; Haider, Maryam; Cohen-Gadol, Aaron A.; El Ahmadieh, Tarek Y.; Yu, Kenny; Neurological Surgery, School of MedicineBackground/Aim: To systematically review the patient characteristics and management approaches of adenoid cystic carcinoma (ACC) infiltrating the skull base.

We systematically reviewed the literature on craniopharyngiomas invading the ventricles (CP-V). Materials and methods: PubMed, EMBASE, Scopus, Web of Science, and Cochrane were searched to include studies reporting clinical data of patients with CP-Vs. Clinico-radiological features, management, and treatment outcomes were analyzed. Results: We included 73 studies encompassing 407 patients. Patients were mostly male (61.5%), presenting with headache (57.9%) and/or endocrine disorders (52.1%). CP-Vs mostly involved the third ventricle (96.3%), followed by the lateral ventricles (2.9%), and the fourth ventricle (1%). Tumors had cystic components in 59% of cases and were mostly adamantinomatous (70.8%). Open resection was performed in 232 cases (57%), mostly with trans-lamina terminalis (36.6%) and trans-callosal (31.9%) approaches. Endoscopic resection was performed in 169 cases (41.5%), mostly with trans-sphenoidal (74.6%) and transventricular (24.9%) approaches. Gross-total tumor resection was obtained in most cases (62.9%). Adjuvant radiotherapy was delivered in 22.8% cases. A total of 178 patients experienced persistent complications, mostly including diabetes insipidus (47.1%) and panhypopituitarism (12.7%), not significantly different after open versus endoscopic resection (p=0.117). Symptom improvement was obtained in 88% of cases. CP-Vs recurrences were reported in 94 patients (23.1%), with median progression-free survival of 13.5 months (range=0.5-252.0 months). Fifty-nine patients died (14.5%), with median overall survival of 32.0 months (range=0.5-252.0 months), significantly longer after endoscopic resection than open resection (p=0.019). Conclusion: CP-Vs are uncommon and challenging entities. Surgical resection is feasible, but patient-tailored selection of open/endoscopic approaches is necessary to achieve optimal outcomes and minimize complication risks.Item Early Morning Cortisol Level as a Predictive Factor for Long-Term Glucocorticoid Replacement After Pituitary Surgery: A Systematic Review and Meta-Analysis(Elsevier, 2023-08) Abdollahifard, Saeed; Taherifard, Erfan; Sadeghi, Alireza; Farrokhi, Amirmohammad; Cohen-Gadol, Aaron A.; Palmisciano, Paolo; Neurosurgery, School of MedicineBackground A reliable strategy for predicting long-term adrenal insufficiency after pituitary surgery can reduce the risk of glucocorticoid overexposure or missing patients with pituitary insufficiency. For this purpose, we aimed to assess the predictive value of early postoperative morning serum cortisol level for the detection of hypothalamic-pituitary-adrenal axis dysfunction in patients who underwent pituitary surgery. Methods A Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA)–based systematic review was conducted to include articles investigating morning blood cortisol levels after pituitary surgery for lesions of the pituitary gland as a determinant for administration of long-term supplemental glucocorticoids. Bayesian statistics were used to pool the sensitivity and specificity rates. Sensitivity and specificity were also determined for each potential cortisol level on postoperative day (POD) 1 and POD 2. Results The study included 17 articles encompassing 1648 patients. Morning cortisol levels on POD 1 and POD 2 showed pooled sensitivity rates of 86.4% and 86.6% and pooled specificity rates of 73.1% and 78.2%, respectively, for predicting long-term glucocorticoid replacement after surgery. A cortisol level of 2.1 μg/dL showed the highest sensitivity rate (98.78%), and 22.5 μg/dL showed the highest specificity rate (72.5%) on POD 1. Conclusions In this review and Bayesian meta-analysis, we found that postoperative serum cortisol measurement may have high accuracy in prediction of the long-term need for glucocorticoid administration in patients who underwent pituitary surgery.Item Gliomas Infiltrating the Corpus Callosum: A Systematic Review of the Literature(MDPI, 2022-05-19) Palmisciano, Paolo; Ferini, Gianluca; Watanabe, Gina; Ogasawara, Christian; Lesha, Emal; Bin-Alamer, Othman; Umana, Giuseppe E.; Yu, Kenny; Cohen-Gadol, Aaron A.; El Ahmadieh, Tarek Y.; Haider, Ali S.; Neurological Surgery, School of MedicineBackground: Gliomas infiltrating the corpus callosum (G-I-CC) majorly impact patient quality-of-life, but maximally safe tumor resection is challenging. We systematically reviewed the literature on G-I-CC. Methods: PubMed, EMBASE, Scopus, Web of Science, and Cochrane were searched following the PRISMA guidelines to include studies of patients with G-I-CC. Clinicopathological features, treatments, and outcomes were analyzed. Results: We included 52 studies comprising 683 patients. Most patients experienced headache (33%), cognitive decline (18.7%), and seizures (17.7%). Tumors mostly infiltrated the corpus callosum genu (44.2%) with bilateral extension (85.4%) into frontal (68.3%) or parietal (8.9%) lobes. Most G-I-CC were glioblastomas (84.5%) with IDH-wildtype (84.9%) and unmethylated MGMT promoter (53.5%). Resection (76.7%) was preferred over biopsy (23.3%), mostly gross-total (33.8%) and subtotal (32.5%). The tumor-infiltrated corpus callosum was resected in 57.8% of cases. Radiation was delivered in 65.8% of patients and temozolomide in 68.3%. Median follow-up was 12 months (range, 0.1−116). In total, 142 patients (31.8%) experienced post-surgical complications, including transient supplementary motor area syndrome (5.1%) and persistent motor deficits (4.3%) or abulia (2.5%). Post-treatment symptom improvement was reported in 42.9% of patients. No differences in rates of complications (p = 0.231) and symptom improvement (p = 0.375) were found in cases with resected versus preserved corpus callosum. Recurrences occurred in 40.9% of cases, with median progression-free survival of 9 months (0.1−72). Median overall survival was 10.7 months (range, 0.1−116), significantly longer in low-grade tumors (p = 0.013) and after resection (p < 0.001), especially gross-total (p = 0.041) in patients with high-grade tumors. Conclusions: G-I-CC show clinicopathological patterns comparable to other more frequent gliomas. Maximally safe resection significantly improves survival with low rates of persistent complications.Item Is intraoperative MRI use in malignant brain tumor surgery a health care burden? A matched analysis of MarketScan Database(Springer, 2022-11) Sharma, Mayur; Wang, Dengzhi; Palmisciano, Paolo; Ugiliweneza, Beatrice; Woo, Shiao; Nelson, Megan; Miller, Donald; Savage, Jesse; Boakye, Maxwell; Andaluz, Norberto; Mistry, Akshitkumar M.; Chen, Clark C.; Williams , Brian J.; Neurological Surgery, School of MedicineBackground: Intraoperative magnetic resonance imaging (iMRI) is a useful adjunct for resection of primary malignant brain tumors (MBTs). The aim of our study is to investigate the impact of iMRI on health care utilization in patients who underwent craniotomy for resection of MBTs. Materials and methods: MarketScan database were queried using the ICD-9/10 and CPT 4th edition, from 2008 to 2020. We included patients ≥ 18 years of age who underwent a craniotomy with at-least one year follow-up. Outcomes were length of stay (LOS), discharge disposition, hospital/emergency room (ER) re-admissions, outpatient services, medication refills and corresponding payments. Results: Of 6,640 patients who underwent craniotomy for MBTs, 465 patients (7%) had iMRI used during the procedure with 0.7% per year increase in iMRI use during the study period. Patients without iMRI use had higher complications at index hospitalization compared to those with iMRI use (19% vs. 14%, p = 0.04). There was no difference in the ER admission rates among the patients who underwent surgery with and without iMRI use at 6-months and 1-year after the index procedure. In terms of post-discharge payments, no significant differences were noted among the patients without and with iMRI use at 6-months ($81,107 vs. $ 81,458, p = 0.26) and 1-year ($132,657 vs. $ 118,113, p = 0.12). Conclusion: iMRI use during craniotomy for MBT gradually increased during the study period. iMRI did not result in higher payments at index hospitalization, 6-months, and 1-year after the index procedure.Item LMD-10. The role of immune checkpoint inhibitors in leptomeningeal disease: a systematic review(Oxford University Press, 2021-08) Palmisciano, Paolo; Haider, Ali S.; Nwagwu, Chibueze D.; Wahood, Waseem; Sagoo, Navraj S.; Yu, Kenny; Ene, Chibawane I.; O’Brien, Barbara J.; Cohen-Gadol, Aaron A.; El Ahmadieh, Tarek Y.; Neurological Surgery, School of MedicineBackground: Leptomeningeal disease (LMD) is a devastating complication of advanced malignancy with a poor prognosis and limited therapeutic options. Whether immune checkpoint inhibitors (ICIs) alter disease course is unknown. Methods: We searched PubMed, EMBASE, Scopus, Cochrane, and clinicaltrials.gov according to PRISMA guidelines to analyze the therapeutic role and toxicity profiles of ICIs in the management of LMD. Studies reporting clinical outcome data of patients with LMD treated with ICIs were included. A comprehensive review of clinical characteristics and survival analysis was conducted. Results: We included 14 studies encompassing 61 patients. The median age at LMD diagnosis was 57 years (female=63.9%). Lung cancer (44.3%), breast cancer (27.9%), and melanoma (23.0%) were the most frequent primary tumors. Parenchymal brain metastases occurred in 37 patients, mostly treated with radiotherapy (83.3%). LMD most frequently presented with headache (42.1%) and was diagnosed by MRI findings (leptomeningeal T1-contrast enhancement: 96.7%) and/or positive cerebrospinal fluid cytology (86.5%). Patients received ICIs for a median duration of 7 months (range, 0.5–58.0): pembrolizumab (49.2%), nivolumab (32.8%), and/or ipilimumab (18.0%). The most common concurrent LMD treatments were radiotherapy (54.7%) and steroids (35.7%). Radiological responses at 6-months were complete (33.3%) and partial response (12.5%), stable disease (33.3%), and progression (20.8%). 22 patients developed ICI-related adverse events, mostly mild (100%) and uncommonly severe (15.6%). Median progression-free survival was 5.1 months, median overall survival was 6.3 months, and 12-month survival was 32.1%. Survival was correlated with ICIs (P=0.042), but not with primary tumors (P=0.144). Patients concurrently receiving steroids showed worse survival (P=0.040), with a median overall survival of 1.9 months. Conclusion: ICI therapy shows promise and appears to be well-tolerated in patients with LMD. Concurrent use of steroids is associated with worse survival. The role of ICIs in the multimodal management of LMD and their combination with steroids requires further analysis.Item Metastases in the Pineal Region: A Systematic Review of Clinical Features, Management Strategies, and Survival Outcomes(Elsevier, 2022) Palmisciano, Paolo; Ogasawara, Christian; Nwagwu, Chibueze D.; Bin Alamer, Othman; Gupta, Aditya D.; Giantini-Larsen, Alexandra M.; Scalia, Gianluca; Yu, Kenny; Umana, Giuseppe E.; Cohen-Gadol, Aaron A.; El Ahmadieh, Tarek Y.; Haider, Ali S.; Neurological Surgery, School of MedicineBackground: Pineal region metastases are rare but often cause severe neurologic deficits. Surgical resection and chemoradiotherapy can provide therapeutic benefit. We investigated the literature to analyze clinical characteristics, management strategies, and survival of adult patients with pineal region metastases. Methods: PubMed, Embase, Scopus, and Cochrane were searched following the PRISMA guidelines, including studies reporting clinical outcomes of patients with pineal region metastases. Clinical presentation, management, and survival were reviewed. Results: We included 31 studies comprising 47 patients. Lung cancer (29.8%) and carcinomas of unknown origin (14.9%) were the most frequent primary tumors. In 48.9% of patients, symptomatic pineal metastases preceded primary tumor diagnosis. Headache (67.4%) and confusion (46.5%) were the most common symptoms. Parinaud syndrome (46.5%) and hydrocephalus (87.2%) were noted. Biopsy (65.9%) was preferred over resection (34.1%), and shunting strategies used were endoscopic third ventriculostomy (43.9%) and ventriculoperitoneal (26.8%). Eleven patients (32.3%) received adjuvant chemotherapy and 32 (68%) received radiotherapy. Posttreatment improvement in symptoms (56.6%) and hydrocephalus (80.5%) were noted. In patients who received adjuvant chemotherapy/radiotherapy, significant improvement in posttreatment performance status occurred with both biopsy (P < 0.001) and resection (P = 0.007). No survival differences were reported between surgery and biopsy (P = 0.912) or between complete and partial resection (P = 0.220). Overall survival was neither influenced by surgical approach (P = 0.157) nor by shunting strategy (P = 0.822). Mean follow-up was 8 months and median overall survival 3 months. Only 2 cases (4.8%) of pineal metastasis showed recurrence. Conclusions: Pineal region metastases carry significant morbidity. Biopsy or surgical resection, combined with adjuvant chemotherapy/radiotherapy and/or shunting, may significantly improve performance status.Item Neoadjuvant Stereotactic Radiotherapy for Brain Metastases: Systematic Review and Meta-Analysis of the Literature and Ongoing Clinical Trials(MDPI, 2022-09-04) Palmisciano, Paolo; Ferini, Gianluca; Khan, Ramlah; Bin-Alamer, Othman; Umana, Giuseppe E.; Yu, Kenny; Cohen-Gadol, Aaron A.; El Ahmadieh, Tarek Y.; Haider, Ali S.; Neurological Surgery, School of MedicineBackground: Brain metastases (BMs) carry a high morbidity and mortality burden. Neoadjuvant stereotactic radiotherapy (NaSRT) has shown promising results. We systematically reviewed the literature on NaSRT for BMs. Methods: PubMed, EMBASE, Scopus, Web-of-Science, Cochrane, and ClinicalTrial.gov were searched following the PRISMA guidelines to include studies and ongoing trials reporting NaSRT for BMs. Indications, protocols, and outcomes were analyzed using indirect random-effect meta-analyses. Results: We included 7 studies comprising 460 patients with 483 BMs, and 13 ongoing trials. Most BMs originated from non-small lung cell carcinoma (41.4%), breast cancer (18.7%) and melanoma (43.6%). Most patients had single-BM (69.8%) located supratentorial (77.8%). Patients were eligible if they had histologically-proven primary tumors and ≤4 synchronous BMs candidate for non-urgent surgery and radiation. Patients with primary tumors clinically responsive to radiotherapy, prior brain radiation, and leptomeningeal metastases were deemed non-eligible. Median planning target volume was 9.9 cm3 (range, 2.9-57.1), and NaSRT was delivered in 1-fraction (90.9%), 5-fraction (4.8%), or 3-fraction (4.3%), with a median biological effective dose of 39.6 Gy10 (range, 35.7-60). Most patients received piecemeal (76.3%) and gross-total (94%) resection after a median of 1-day (range, 1-10) post-NaSRT. Median follow-up was 19.2-months (range, 1-41.3). Actuarial post-treatment rates were 4% (95%CI: 2-6%) for symptomatic radiation necrosis, 15% (95%CI: 12-18%) and 47% (95%CI: 42-52%) for local and distant recurrences, 6% (95%CI: 3-8%) for leptomeningeal metastases, 81% (95%CI: 75-87%) and 59% (95%CI: 54-63%) for 1-year local tumor control and overall survival. Conclusion: NaSRT is effective and safe for BMs. Ongoing trials will provide high-level evidence on long-term post-treatment outcomes, further compared to adjuvant stereotactic radiotherapy.Item Orbital Exenteration for Craniofacial Lesions: A Systematic Review and Meta-Analysis of Patient Characteristics and Survival Outcomes(MDPI, 2023-08-27) Qedair, Jumanah; Haider, Ali S.; Balasubramanian, Kishore; Palmisciano, Paolo; Hassan, Taimur; Shahbandi, Ataollah; Sabahi, Mohammadmahdi; Kharbat, Abdurrahman F.; Abou-Al-Shaar, Hussam; Yu, Kenny; Cohen-Gadol, Aaron A.; El Ahmadieh, Tarek Y.; Bin-Alamer, Othman; Neurological Surgery, School of MedicineBackground: The outcomes of orbital exenteration (OE) in patients with craniofacial lesions (CFLs) remain unclear. The present review summarizes the available literature on the clinical outcomes of OE, including surgical outcomes and overall survival (OS). Methods: Relevant articles were retrieved from Medline, Scopus, and Cochrane according to PRISMA guidelines. A systematic review and meta-analysis were conducted on the clinical characteristics, management, and outcomes. Results: A total of 33 articles containing 957 patients who underwent OE for CFLs were included (weighted mean age: 64.3 years [95% CI: 59.9-68.7]; 58.3% were male). The most common lesion was squamous cell carcinoma (31.8%), and the most common symptom was disturbed vision/reduced visual acuity (22.5%). Of the patients, 302 (31.6%) had total OE, 248 (26.0%) had extended OE, and 87 (9.0%) had subtotal OE. Free flaps (33.3%), endosseous implants (22.8%), and split-thickness skin grafts (17.2%) were the most used reconstructive methods. Sino-orbital or sino-nasal fistula (22.6%), flap or graft failure (16.9%), and hyperostosis (13%) were the most reported complications. Regarding tumor recurrences, 38.6% were local, 32.3% were distant, and 6.7% were regional. The perineural invasion rate was 17.4%, while the lymphovascular invasion rate was 5.0%. Over a weighted mean follow-up period of 23.6 months (95% CI: 13.8-33.4), a weighted overall mortality rate of 39% (95% CI: 28-50%) was observed. The 5-year OS rate was 50% (median: 61 months [95% CI: 46-83]). The OS multivariable analysis did not show any significant findings. Conclusions: Although OE is a disfiguring procedure with devastating outcomes, it is a viable option for carefully selected patients with advanced CFLs. A patient-tailored approach based on tumor pathology, extension, and overall patient condition is warranted.
