Abstract
OBJECTIVE To assess the effect of wait and scan (W&S) and stereotactic radiosurgery (SRS) on health-related quality of life (HRQoL) over time in patients with a stable vestibular schwannoma (VS) and growing VS. STUDY DESIGN Longitudinal, multicenter, observational study. SETTING Tertiary expert center for VS (Radboudumc Nijmegen) and Gamma-Knife center ETZ Hospital Tilburg. METHODS Changes in HRQoL, measured with the Penn Acoustic Neuroma Quality-of-Life (PANQOL), and the physical and mental component summary scores (PCS and MCS, respectively) derived from the 36-Item Short Form Health Survey (SF-36), were compared among patients managed by W&S and SRS between 2017 and 2022. Second, HRQoL over time in patients with a growing VS was compared between W&S and SRS. RESULTS Differences in PANQOL total and subdomain scores, PCS and MCS scores over time in the W&S (n = 73) and SRS (n = 170) groups were nonsignificant and on average did not exceed the minimal clinically important differences (mean difference of -2.56 [PANQOL total], 1.22 [PCS], and -1.76 [MCS]; all P > .05). In growing VS, comparison of W&S (n = 29) and SRS (n = 154) also revealed no significant difference (mean difference of 1.19 (PANQOL total), 1.83 (PCS) and -0.12 (MCS); all P > .05). CONCLUSION Differences in HRQoL in patients with VS are minor and not significantly different or clinically relevant between patients managed with W&S or SRS. Similarly, patients with a growing VS managed with W&S or SRS exhibit no significant or clinical relevant difference in HRQoL during follow-up. This can aid clinicians in the counseling of patients regarding HRQoL when deciding on a management strategy after diagnosis or documented growth.

Abstract
OBJECTIVE The current extent of otolaryngologic cancer care regionalization is unclear. This study characterizes case volume regionalization patterns for 4 distinct otolaryngologic tumors-head and neck squamous cell carcinomas (HNSCCs), thyroid cancers (TCs), vestibular schwannomas, and pituitary adenomas (PAs). METHODS The 2010-2016 National Cancer Database was queried for patients with HNSCCs, TCs, vestibular schwannomas, and PAs. Facility geographic locations were divided into 4 geographical quadrants. High-volume facilities (HVFs) were defined as top 100 by volume facility for ≥1 pathology. RESULTS A total of 191/1342 facilities (4.2%) were defined as an HVF. Vestibular schwannoma was the most regionalized, with 65.9% of patients treated at an HVF. Thyroid cancer (37.4%) and HNSCC (38.8%) were the least commonly treated at HVFs. Forty-one/191 (21.5%) were classified as HVFs for all 4 pathologies. Factors predictive of treatment at HVFs included age <65, higher income, and private insurance, larger tumor size, and lower American Joint Committee on Cancer stage. CONCLUSION Over 20% of HVFs were considered high-volume for all 4 pathologies. Vestibular schwannomas were the most regionalized compared with PAs, TCs, and HSNCCs.

Abstract
Vestibular schwannomas (VS) are benign intracranial tumors posing significant management challenges. This study aims to compare the outcomes of stereotactic radiosurgery (SRS) and watchful waiting (WW) in the management of newly diagnosed VS, integrating findings from both retrospective and the pioneering V-REX prospective trial. Adhering to PRISMA guidelines, a systematic review was conducted using MEDLINE, Embase, and Cochrane databases. Studies directly comparing SRS with WW for newly diagnosed VS were included. Primary outcomes focused on hearing preservation assessed through the AAO-HNS or Gardner-Robertson hearing classification scales and tumor progression, with secondary outcomes focusing on neurological symptoms, and the need for further treatment. Thirteen studies encompassing 1,635 patients (WW: 891; SRS: 744) were included.While no significant difference was found in serviceable hearing loss at last follow-up (RR = 1.51, [95%CI: 0.98, 2.32], p = 0.06), significant differences favoring WW were observed in pure tone audiometry (PTA) (MD = -13.51 [95%CI: -22.66, -4.37], p = 0.004) and word recognition score (WRS) (MD = 20.48 [95%CI: 9.72, 31.25], p = 0.0002). Analysis of tumor progression indicated no overall significant difference in risk between SRS and WW (RR = 0.40, [95%CI 0.07, 2.40], p = 0.32), but subgroup analysis suggested a lower risk with SRS in certain contexts. The need for further treatments favored SRS (RR = 0.24, [95%CI: 0.07, 0.74], p = 0.007). No significant differences were found in tinnitus and imbalance between the two groups. This comprehensive analysis suggests no marked difference in functional hearing preservation between SRS and WW in managing VS. However, untreated tumors commonly necessitate additional interventions. These findings highlight the need for individualized treatment decisions and underscore the importance of continued monitoring. The study advocates for further prospective trials to refine management strategies for VS.

Abstract
Vestibular schwannomas are rare intracranial tumors originating from Schwann cells of the vestibular nerve. Despite their benign nature, these tumors can exert significant mass effects and debilitating symptoms, including gradual hearing loss, vertigo, facial nerve dysfunction, and headaches. Current clinical management options encompass wait-and-scan, surgery, radiation therapy, and off-label medication. However, each approach exhibits its own challenges and harbors limitations that underscore the urgent need for therapeutic treatments. Over the past 2 decades, extensive elucidation of the molecular underpinnings of vestibular schwannomas has unraveled genetic anomalies, dysregulated signaling pathways, downstream of receptor tyrosine kinases, disrupted extracellular matrix, inflammatory tumor microenvironment, and altered cerebrospinal fluid composition as integral factors in driving the development and progression of the disease. Armed with this knowledge, novel therapeutic interventions tailored to the unique molecular characteristics of those conditions are actively being pursued. This review underscores the urgency of addressing the dearth of Food and Drug Administration-approved drugs for vestibular schwannoma, highlighting the key molecular discoveries and their potential translation into therapeutics. It provides an in-depth exploration of the evolving landscape of therapeutic development, which is currently advancing from bench to bedside. These ongoing efforts hold the promise of significantly transforming the lives of vestibular schwannoma patients in the future.

Abstract
OBJECTIVE To review the literature on the diagnosis and treatment of vestibular schwannoma. METHODS Task force members were educated on knowledge synthesis methods, including electronic database search, review and selection of relevant citations, and critical appraisal of selected studies. Articles written in English or Portuguese on vestibular schwannoma were eligible for inclusion. The American College of Physicians' guideline grading system and the American Thyroid Association's guideline criteria were used for critical appraisal of evidence and recommendations for therapeutic interventions. RESULTS The topics were divided into 2 parts: (1) Diagnosis - audiologic, electrophysiologic tests, and imaging; (2) Treatment - wait and scan protocols, surgery, radiosurgery/radiotherapy, and systemic therapy. CONCLUSIONS Decision making in VS treatment has become more challenging. MRI can diagnose increasingly smaller tumors, which has disastrous consequences for the patients and their families. It is important to develop an individualized approach for each case, which highly depends on the experience of each surgical team.

Abstract
PURPOSE to predict vestibular schwannoma (VS) response to radiosurgery by applying machine learning (ML) algorithms on radiomic features extracted from pre-treatment magnetic resonance (MR) images. METHODS patients with VS treated with radiosurgery in two Centers from 2004 to 2016 were retrospectively evaluated. Brain T1-weighted contrast-enhanced MR images were acquired before and at 24 and 36 months after treatment. Clinical and treatment data were collected contextually. Treatment responses were assessed considering the VS volume variation based on pre- and post-radiosurgery MR images at both time points. Tumors were semi-automatically segmented and radiomic features were extracted. Four ML algorithms (Random Forest, Support Vector Machine, Neural Network, and extreme Gradient Boosting) were trained and tested for treatment response (i.e., increased or non-increased tumor volume) using nested cross-validation. For training, feature selection was performed using the Least Absolute Shrinkage and Selection Operator, and the selected features were used as input to separately build the four ML classification algorithms. To overcome class imbalance during training, Synthetic Minority Oversampling Technique was used. Finally, trained models were tested on the corresponding held out set of patients to evaluate balanced accuracy, sensitivity, and specificity. RESULTS 108 patients treated with Cyberknife® were retrieved; an increased tumor volume was observed at 24 months in 12 patients, and at 36 months in another group of 12 patients. The Neural Network was the best predictive algorithm for response at 24 (balanced accuracy 73% ± 18%, specificity 85% ± 12%, sensitivity 60% ± 42%) and 36 months (balanced accuracy 65% ± 12%, specificity 83% ± 9%, sensitivity 47% ± 27%). CONCLUSIONS radiomics may predict VS response to radiosurgery avoiding long-term follow-up as well as unnecessary treatment.

Abstract
PURPOSE OF REVIEW Neurofibromatosis 2 (NF2) is an autosomal-dominant genetic disorder characterized by bilateral vestibular schwannomas (VS), meningiomas, ependymomas, spinal and peripheral schwannomas, optic gliomas, and juvenile cataracts. Ongoing studies provide new insight into the role of the NF2 gene and merlin in VS tumorigenesis. RECENT FINDINGS As NF2 tumor biology becomes increasingly understood, therapeutics targeting specific molecular pathways have been developed and evaluated in preclinical and clinical studies. NF2-associated VS are a source of significant morbidity with current treatments including surgery, radiation, and observation. Currently, there are no FDA-approved medical therapies for VS, and the development of selective therapeutics is a high priority. This manuscript reviews NF2 tumor biology and current therapeutics undergoing investigation for treatment of patients with VS.

Abstract
OBJECTIVE Management of small vestibular schwannoma (VS) remains controversial, as patients are typically candidates for all three management options including microsurgery, stereotactic radiosurgery, or wait-and-scan. This study compares patient satisfaction across treatment modalities in patients with small VS. STUDY DESIGN Cross-sectional study. SETTING Survey distributed to members of the Acoustic Neuroma Association and Mayo Clinic patients. METHODS Patients with small (<1 cm in any location) sporadic VS who completed at least one survey regarding treatment history and patient satisfaction were included. RESULTS Among 346 patients with small VS, 106 (31%) underwent microsurgery, 78 (23%) radiosurgery, 152 (44%) wait-and-scan, and 10 (3%) multimodal treatment. Collectively, 307 (89%) patients indicated "Yes, I am happy with my treatment type and in hindsight I would not change anything," and 39 (11%) indicated "No, in hindsight I would have chosen a different treatment type." Satisfaction differed significantly by treatment group with 85, 86, 96, and 40% of patients in the microsurgery, radiosurgery, wait-and-scan, and multimodal groups reporting that they were satisfied with treatment, respectively ( p < 0.001). Satisfaction also differed significantly among those undergoing upfront treatment with microsurgery or radiosurgery (81%), initial wait-and-scan followed by treatment (88%), and wait-and-scan only groups (96%; p = 0.001). Specifically, the wait-and-scan only group demonstrated greater satisfaction compared with the other two treatment strategies ( p < 0.05 for both). CONCLUSIONS Patient satisfaction with the management of small VS is generally high. Management with wait-and-scan, even if treatment is eventually pursued, may offer higher patient satisfaction compared with upfront treatment.

Abstract
BACKGROUND Vestibular schwannomas are benign tumours for which various treatments are available. We performed a systematic review of prospective controlled trials comparing the patient-relevant benefits and harms of single-fraction stereotactic radiosurgery (sfSRS) with microsurgical resection (MR) in patients with vestibular schwannoma. METHODS We searched for randomized controlled trials (RCTs) and non-randomized prospective controlled trials in MEDLINE, Embase, the Cochrane Central Register of Controlled Trials, and study registries (last search: 09/2021) and also screened reference lists of relevant systematic reviews. Manufacturers were asked to provide unpublished data. Eligible studies investigated at least one patient-relevant outcome. We assessed the risk of bias (high or low) at the study and outcome level. If feasible, meta-analyses were performed. We graded the results into different categories (hint, indication, or proof of greater benefit or harm). RESULTS We identified three non-randomized prospective controlled trials of generally low quality with evaluable data on 339 patients with unilateral vestibular schwannoma. There was an indication of greater benefit of sfSRS compared with MR for facial palsy (OR 0.06, 95% CI 0.02-0.21, p < 0.001, 2 studies), hearing function (no pooled estimate available, 2 studies), and length of hospital stay (no pooled estimate available, 2 studies). We found no clinically relevant differences for mortality, vertigo, headaches, tinnitus, balance function, work disability, adverse events, and health-related quality of life. CONCLUSIONS Our systematic review indicates that sfSRS has greater benefits than MR in patients with unilateral vestibular schwannoma. However, it is unclear whether this conclusion still holds after 2 years, as long-term studies are lacking. It is also unclear whether the effects of sfSRS are similar in patients with bilateral vestibular schwannomas. Long-term prospective studies including patients with this condition would therefore be useful.

Introduction Survival amongst posterior fossa tumour (PFT) patients is improving. Clinical endpoints such as overall survival fail to depict QoL. There is yet to be a review of current QoL instruments used for adult PFTs. Aim of this review is to outline the QoL reporting in the management of PFTs and measure participation level. Methods This systematic review was conducted in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analysis. A search strategy to identify adult patients with PFTs who took part in QoL metrics was conducted. Observational and experimental studies published from 1990 to date were included. Studies with a sample size less than 10 and performance measures such as Karnofsky Performance Status were not considered. Results A total of 116 studies were included in the final analysis. Vestibular schwannomas were the most common tumour pathology (n = 23,886, 92.6%) followed by pilocytic astrocytomas (n = 657, 2.5%) and meningiomas (n = 437, 1.7%) Twenty-five different QoL measures were used in the study pool. SF-36 was the most common (n = 55, 17 47.4%) QoL metric in the whole study pool, followed by the Penn Acoustic Neuroma QoL scale (n = 24, 20.7%) and Dizziness Handicap Inventory (n = 16, 13.8%). Seventy-two studies reported less-than 100% participation in QoL evaluation. The commonest reason for non-participation was a lack of response (n = 1,718, 60.8%), incomplete questionnaires (n = 268, 9.4%) and cognitive dysfunction (n = 258, 9.1%). Conclusion Informed clinical decision-making in PFT patients requires the development of specific QoL outcomes. Core outcome sets, and minimal clinically important differences (MCID) are essential for these metrics to show clinically significant improvements in patient QoL.

Abstract
ObjectiveHealth-related quality of life (HRQoL) and self-reported outcome measures have a relevant impact on the medical decision-making process. They capture either the current status and allow for multiple prospective evaluations in the course of a treatment or rely on the retrospective comparison of health of patients before and after an intervention to assess its benefit. Importantly, these patient-assessed measures may be influenced by psychological factors. We compared HRQoL and perceived benefit in the course of surgical vestibular schwannoma (VS) treatment, as assessed by the patients from a prospective and retrospective point-of-view, and evaluated the influence of co-morbid depression.MethodsWithin a prospective observational single-center study, forty-three patients with VS were investigated before and after retrosigmoid tumor resection. SF-36, Beck Depression Inventory and patient-assessed clinical symptoms were acquired before surgery and at follow-up. At follow-up, the Glasgow Benefit Inventory (GBI) was acquired as well.ResultsSF-36 scores were significantly lower than the age and sex matched normative data in six and three out of eight categories before and after surgery, respectively. Three categories improved significantly after vs. before surgery; one of them (global health) reached a minimal clinical important difference. In contrast, patients reported predominantly a deterioration, when asked for a retrospective evaluation of the benefit (i.e., GBI). Depression correlated with both SF-36 and GBI, determined dissatisfaction, improved significantly after surgery and was the measure that had the largest impact on HRQoL.ConclusionProspective and retrospective HRQoL measures may lead to different findings and can be confounded by psychological factors.

Abstract
BACKGROUND Vestibular schwannoma (VS) is the most common tumour of the cerebellopontine angle. Owing to complex anatomy and high rates of morbidity, surgical management of large tumours is challenging. We seek to explore the clinical landscape of VS to identify predictors of outcome and help guide surgical decision making. METHODS We retrospectively reviewed charts of patients who underwent primary surgery for VS between 2005 and 2020 at a quaternary referral center in Toronto, Canada. Mined data includes patient demographics, clinical presentation, radiological features, and treatment details. Regression modelling was used to identify predictors of tumour control, postoperative morbidity, and correlates of progression free survival (PFS). RESULTS Two hundred and five tumours with sufficient data were included in our study. Syndromic NF2, large tumours (>3cm), subtotal resection (vs gross total resection), presence of edema on preoperative MRI, and preoperative trigeminal symptoms were all predictors of postoperative progression/need for further treatment; the latter four were also associated with shorter progression free survival. Extent of resection (EOR), tumour size, and Koos grade were independently predictive of postoperative progression/secondary intervention in multivariate models; however, only EOR was independently predictive of progression-free survival. EOR, tumour size, and patient age are each independently predictive of facial nerve outcome. CONCLUSIONS We comprehensively explore the clinical landscape of surgically treated vestibular schwannoma and highlight important outcome predictors and disease subgroups. This may have important implications in risk stratifying these challenging cases.

Minimally invasive surgical treatment of intracranial meningiomas in elderly patients (≥ 65 years): outcomes, readmissions, and tumor control. Neurosurg Focus 2021; 49:E17. [PMID: 33002879 DOI: 10.3171/2020.7.focus20515] [Citation(s) in RCA: 11] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/01/2020] [Accepted: 07/21/2020] [Indexed: 11/06/2022]
Abstract
OBJECTIVE Increased lifespan has led to more elderly patients being diagnosed with meningiomas. In this study, the authors sought to analyze and compare patients ≥ 65 years old with those < 65 years old who underwent minimally invasive surgery for meningioma. To address surgical selection criteria, the authors also assessed a cohort of patients managed without surgery. METHODS In a retrospective analysis, consecutive patients with meningiomas who underwent minimally invasive (endonasal, supraorbital, minipterional, transfalcine, or retromastoid) and conventional surgical treatment approaches during the period from 2008 to 2019 were dichotomized into those ≥ 65 and those < 65 years old to compare resection rates, endoscopy use, complications, and length of hospital stay (LOS). A comparator meningioma cohort of patients ≥ 65 years old who were observed without surgery during the period from 2015 to 2019 was also analyzed. RESULTS Of 291 patients (median age 60 years, 71.5% females, mean follow-up 36 months) undergoing meningioma resection, 118 (40.5%) were aged ≥ 65 years and underwent 126 surgeries, including 20% redo operations, as follows: age 65-69 years, 46 operations; 70-74 years, 40 operations; 75-79 years, 17 operations; and ≥ 80 years, 23 operations. During 2015-2019, of 98 patients referred for meningioma, 67 (68%) had surgery, 1 (1%) had radiosurgery, and 31 (32%) were observed. In the 11-year surgical cohort, comparing 173 patients < 65 years versus 118 patients ≥ 65 years old, there were no significant differences in tumor location, size, or outcomes. Of 126 cases of surgery in 118 elderly patients, the approach was a minimally invasive approach to skull base meningioma (SBM) in 64 cases (51%) as follows: endonasal 18, supraorbital 28, minipterional 6, and retrosigmoid 12. Endoscope-assisted surgery was performed in 59.5% of patients. A conventional approach to SBM was performed in 15 cases (12%) (endoscope-assisted 13.3%), and convexity craniotomy for non-skull base meningioma (NSBM) in 47 cases (37%) (endoscope-assisted 17%). In these three cohorts (minimally invasive SBM, conventional SBM, and NSBM), the gross-total/near-total resection rates were 59.5%, 60%, and 91.5%, respectively, and an improved or stable Karnofsky Performance Status score occurred in 88.6%, 86.7%, and 87.2% of cases, respectively. For these 118 elderly patients, the median LOS was 3 days, and major complications occurred in 10 patients (8%) as follows: stroke 4%, vision decline 3%, systemic complications 0.7%, and wound infection or death 0. Eighty-three percent of patients were discharged home, and readmissions occurred in 5 patients (4%). Meningioma recurrence occurred in 4 patients (3%) and progression in 11 (9%). Multivariate regression analysis showed no significance of American Society of Anesthesiologists physical status score, comorbidities, or age subgroups on outcomes; patients aged ≥ 80 years showed a trend of longer hospitalization. CONCLUSIONS This analysis suggests that elderly patients with meningiomas, when carefully selected, generally have excellent surgical outcomes and tumor control. When applied appropriately, use of minimally invasive approaches and endoscopy may be helpful in achieving maximal safe resection, reducing complications, and promoting short hospitalizations. Notably, one-third of our elderly meningioma patients referred for possible surgery from 2015 to 2019 were managed nonoperatively.

Abstract
BACKGROUND Optimal management of vestibular schwannoma (VS) is still debated and thus international consensus has not been achieved. Treatment options are observation, radiotherapy, and surgery. Knowledge on the natural history of tumor growth is essential for choice of treatment modality. The aim is to present intra-/extrameatal tumor growth and management data from a prospective, unselected national cohort of patients diagnosed with VS during the period 1976-2015. METHODS Since 1976, all data from patients diagnosed with sporadic VS in Denmark have been referred to our national treatment center, where they have been entered prospectively into the national database. Data on tumor localization, growth, and treatment were retrieved. Growth definition: >2 mm by linear measurement, in accordance with the Tokyo 2001 consensus-meeting recommendations. RESULTS 3637 cases of VS were diagnosed, in which 1304 patients had surgery and 21 received radiotherapy post diagnosis. 2312 patients were observed with mean follow-up of 7.33 years. Of these, 434(19%; 102 intra-and 332 extrameatal tumors) changed to active treatment during the observation period due to tumor growth. 5 years after diagnosis, 21% of the intrameatal tumors exhibited growth during observation, whereas 37% of extrameatal tumors had grown, increasing to 25% intrameatal and 42% extrameatal after 10 years. Following growth, the intrameatal tumors were mostly observed further and the extrameatal mostly underwent surgery. Tumor growth occurred mainly within the first 5 years post diagnosis. CONCLUSION This natural history study documents the growth occurrence of both intra-and extrameatal VS during the first 12 years after diagnosis and should be used in patient counseling, management, and treatment decision making.

Abstract
Majority of the published literature on the impact of microsurgery over quality-of-life (QOL) in vestibular schwannoma (VS) patients is retrospective in nature, with variable results, and there has been very little contribution from South-Asia. The authors designed this study to investigate the role of microsurgery in QOL alterations in VS patients, and to compare obtained QOL scores with that of control population. Between February 2017 and March 2018, a prospective/retrospective study was done at our institute. Prospective and retrospective cohorts included, 30 and 34 consecutive patients, respectively, of unilateral VS undergoing microsurgery. QOL assessment was done using Short Form-36 (SF-36), and the Penn Acoustic Neuroma Quality-Of-Life (PANQOL) questionnaires. Prospective cohort underwent QOL assessment at 3 junctures - pre-surgery, 3-months & 1-year post-surgery; while retrospective cohort was assessed only once, at 1-year post-surgery. Age- & sex- matched normal population and diabetic patients were used as controls. In the prospective cohort, patients showed drop in all PANQOL domain/ SF-36 dimension scores at 3-month post-surgery, exception being vitality and general health in SF-36; showed improvement at 1-year follow-up, with majority either levelling or improving their respective pre-surgery scores. Gross total resection, tumors ≤ 3 cm, and age ≤ 45 years had better PANQOL scores at 1-year post-surgery across all the domains. Patients in both the cohorts showed worse QOL compared to normal population, but the gap got narrower at 1-year post-surgery. Our study adds a South-Asian perspective to the pool of prospective knowledge available on QOL following microsurgery in VS patients.

Abstract
OBJECTIVE Through years, interest in quality of life (QoL) among patients affected by vestibular schwannoma (VS) has increased. The expansion of the indications for endoscopic ear surgery allowed the development of the transcanal transpromontorial surgery (TTS) for VS removal. The objective of the present study was to assess QoL in a cohort of VS patients operated on by translabyrinthine (TL), retrosigmoid (RS) and TTS approach. METHODS The study was conducted on 111 patients who underwent surgery for VS between January 2017 and January 2020 at two different institutions. Patients fulfilled three questionnaires during follow-up: Glasgow Benefit Inventory, Depression Anxiety Stress Scales-21 and Penn Acoustic Neuroma Quality-Of-Life. The association between sex, age, date of surgery, tumor size, post-operative facial nerve (FN) function and QoL outcomes was assessed. RESULTS An overall subjective impairment was demonstrated in all groups. Age, Koos staging and FN functions were associated to distinct QoL outcomes. CONCLUSIONS QoL decreases in patients surgically treated for VS. The TTS may allow improved scores in many domains, confirming to be a subjectively well-tolerated technique.

Abstract
OBJECTIVE To examine differences in quality of life in patients with vestibular schwannoma following a single treatment modality: observation, stereotactic radiosurgery (SRS), or microsurgery. STUDY DESIGN Retrospective review. SETTING Tertiary academic medical center. PATIENTS Patients diagnosed with sporadic vestibular schwannoma who had completed at least 2 Penn Acoustic Neuroma Quality of Life (PANQOL) surveys. INTERVENTIONS Treatment via SRS, microsurgery, or observation. MAIN OUTCOME MEASURES PANQOL total survey and subdomain scores. RESULTS One hundred and thirty-four patients (94 observations, 24 SRS, 16 microsurgeries) were included. The mean number of PANQOL surveys completed was 2.8 (range 2-5). The total PANQOL scores were significantly lower in the SRS group, but not the microsurgery group, compared with observation at the time of diagnosis (observation 550.4 ± 58.4; SRS 471.4 ± 37.4; microsurgery 492.6 ± 40.7; p = 0.03). Over time, there were no significant differences in the change of PANQOL scores across the 3 groups (SRS PANQOL score worsened 6.8/year compared with observation, p = 0.3; microsurgery PANQOL score worsened 7.8/year compared with observation, p = 0.5). Anxiety was the only subdomain that significantly worsened over time in the microsurgery group (microsurgery PANQOL score worsened 3.8/year compared with observation; p = 0.009). CONCLUSION Despite differences in PANQOL scores at baseline, changes in total PANQOL score over time were not found to be statistically significant, regardless of the treatment group chosen. Overall, these results hold implications for patient counseling when considering treatment choice and quality of life predictions.

Longitudinal Changes of Quality of Life and Hearing Following Radiosurgery for Vestibular Schwannoma. Cancers (Basel) 2021; 13:cancers13061315.

Abstract
Simple Summary Since vestibular schwannomas are slow-growing tumors that can be controlled with different treatment modalities such as neurosurgery or radiotherapy, preserving quality of life is an important consideration. In this study, we analyzed how quality of life (QoL) changes for patients who receive stereotactic radiation in the months and years after treatment and if there is a correlation between changes in QoL and changes in hearing function. The results suggest that proper hearing of the unaffected ear might compensate for a hearing loss of the other ear due to the tumor or the treatment and in turn preserve QoL. However, this association should be confirmed in additional studies. Abstract Background: Most existing publications on quality of life (QoL) following stereotactic radiosurgery (SRS) for vestibular schwannomas (VS) gather information retrospectively by conducting surveys several years after treatment. The purpose of this study is therefore to provide longitudinal QoL data and assess how changes in hearing impact QoL. Methods: Patients completed the 12-item short-form (SF-12) health survey prior to treatment and at every follow-up visit. One hundred and seventy-five patients who had complete forms prior to treatment as well as at an early and at a late follow-up were included in the analysis. For 51 of these patients, longitudinal audiometry data were available. Results: Median follow-up was 7.2 years. Patients experienced a significant reduction in the physical composite score (PCS, p = 0.011) compared to before treatment. The mental composite score (MCS) increased significantly (p = 0.032). A decrease in PCS was not significantly correlated with an increased hearing threshold on the affected but rather on the unaffected ear (r(49) = −0.32, p = 0.023). Conclusions: It is unclear whether the decline in the PCS is due to treatment-related toxicity or the normal decline of PCS with age. Ensuring proper hearing on the untreated ear might be crucial to ensure good QoL for patients treated with SRS for VS, though this association should be confirmed in additional studies.

Abstract
The level of evidence to provide treatment recommendations for vestibular schwannoma is low compared with other intracranial neoplasms. Therefore, the vestibular schwannoma task force of the European Association of Neuro-Oncology assessed the data available in the literature and composed a set of recommendations for health care professionals. The radiological diagnosis of vestibular schwannoma is made by magnetic resonance imaging. Histological verification of the diagnosis is not always required. Current treatment options include observation, surgical resection, fractionated radiotherapy, and radiosurgery. The choice of treatment depends on clinical presentation, tumor size, and expertise of the treating center. In small tumors, observation has to be weighed against radiosurgery, in large tumors surgical decompression is mandatory, potentially followed by fractionated radiotherapy or radiosurgery. Except for bevacizumab in neurofibromatosis type 2, there is no role for pharmacotherapy.

Abstract
BACKGROUND Previous cross-sectional studies analyzing quality of life (QOL) outcomes in patients with sporadic vestibular schwannoma (VS) have shown surprisingly little difference among treatment modalities. To date, there is limited prospective QOL outcome data available comparing baseline to posttreatment scores. STUDY DESIGN Prospective longitudinal study using the disease-specific Penn Acoustic Neuroma Quality of Life (PANQOL) scale. SETTING Large academic skull base center. PATIENTS Patients diagnosed with unilateral VS who completed a baseline survey before treatment and at least one posttreatment survey. MAIN OUTCOME MEASURES Change in PANQOL scores from baseline to most recent survey. RESULTS A total of 244 patients were studied, including 78 (32%) who elected observation, 118 (48%) microsurgery, and 48 (20%) stereotactic radiosurgery. Patients who underwent microsurgery were younger (p < 0.001) and had larger tumors (p < 0.001) than those who underwent observation or radiosurgery; there was no significant difference in duration of follow-up among management groups (mean 2.1 yrs; p = 0.28). When comparing the total PANQOL score at baseline to the most recent survey, the net change was only -1.1, -0.1, and 0.3 points on a 100-point scale for observation, microsurgery, and radiosurgery, respectively (p = 0.89). After multivariable adjustment for baseline features, there were no statistically significant changes when comparing baseline to most recent scores within each management group for facial function, general health, balance, hearing loss, energy, and pain domains or total score. However, the microsurgical group experienced a 10.8-point improvement (p = 0.002) in anxiety following treatment, compared with 1.5 (p = 0.73) and 5.3 (p = 0.31) for observation and radiosurgery, respectively. CONCLUSIONS In this prospective longitudinal study investigating differences in QOL outcomes among VS treatment groups using the disease-specific PANQOL instrument, treatment did not modify QOL in most domains. Microsurgery may confer an advantage with regard to patient anxiety, presumably relating to the psychological benefit of "cure" from having the tumor removed.

Abstract
Objective We retrospectively evaluated the oncological and functional effectiveness of revision surgery for recurrent or remnant vestibular schwannoma (rVS). Methods We included 29 consecutive patients with unilateral hearing loss (16 women; mean age: 42.2 years) that underwent surgery for rVS. Previous surgeries included gross total resections (GTRs, n=11) or subtotal resections (n=18); mean times to recurrence were 9.45 and 4.15 years, respectively. House–Brackmann (HB) grading of facial nerve (FN) weakness (grades II-IV) indicated that 22 (75.9%) patients had deep, long-lasting FN paresis (HB grades: IV-VI). The mean recurrent tumor size was 23.3 mm (range: 6 to 51). Seven patients had neurofibromatosis type 2. Results All patients received revision GTRs. Fourteen small- to medium-sized tumors located at the bottom of the internal acoustic canal required the translabyrinthine approach (TLA); 12 large and small tumors, predominantly in the cerebellopontine angle, required the retrosigmoid approach (RSA); and 2 required both TLA and RSA. One tumor that progressed to the petrous apex required the middle fossa approach. Fifteen patients underwent facial neurorrhaphy. Of these, 11 received hemihypoglossal–facial neurorrhaphies (HHFNs); nine with simultaneous revision surgery. In follow-up, 10 patients (34.48%) experienced persistent deep FN paresis (HB grades IV-VI). After HHFN, all patients improved from HB grade VI to III (n=10) or IV (n=1). No tumors recurred during follow-up (mean, 3.46 years). Conclusions Aggressive microsurgical rVS treatment combined with FN reconstruction provided durable oncological and neurological effects. Surgery was a reasonable alternative to radiosurgery, particularly in facial neurorrhaphy, where it provided a one-step treatment.

Abstract
Objectives Patients with a vestibular schwannoma (VS) experience a reduced quality of life (QoL). The main objective of this study was to determine the strongest predictors reducing physical and mental QoL from the disease‐specific Penn Acoustic Neuroma Quality of Life (PANQOL) questionnaire in patients with VS. Design Observational study. Setting Radboudumc Skull Base Centre, Nijmegen. Participants Patients newly diagnosed with VS between 2014 and 2017 managed with either observation, stereotactic radiosurgery or microsurgery. Main outcome measures Quality of life was assessed using the disease‐specific PANQOL and general Short‐Form (36) Health Survey (SF‐36). Multiple linear regression models with PANQOL domains as predictors were used to determine the strongest predictors for SF‐36 QoL physical and mental health scores. Standardised beta coefficients (β) were used for ranking. Results A total of 174 patients (50% females, mean age 58.9 years) returned the questionnaires, providing a 69% response rate. Fifteen patients (9%) were treated with microsurgery, 29 (17%) with stereotactic radiosurgery and 130 patients (75%) were observed in a wait and scan strategy. A lack of energy (β = .28; P ≤ .001), lower general health (β = .22; P ≤ .001), headache (β = .16; P ≤ .001), anxiety (β = .15; P ≤ .001) and balance problems (β = .10; P ≤ .001) are the strongest predictors affecting physical health, while mental health is most affected by anxiety (β = .37; P ≤ .001), a lack of energy (β = .34; P ≤ .001), facial nerve dysfunction (β = .07; P ≤ .001), balance problems (β = .04; P ≤ .001) and headaches (β = .04; P ≤ .001). Conclusion A lack of energy, anxiety, headache and balance problems are the strongest predictors of both SF‐36 physical and mental QoL in patients with VS. More awareness and supportive care regarding energy, anxiety, headache and balance in informing, evaluating and treating patients with VS could improve QoL.

Abstract
OBJECTIVE To examine the impact of treatment on disease-specific health-related quality of life (HRQOL) among patients with sporadic vestibular schwannoma (VS). STUDY DESIGN National cross-sectional study. SETTING Tertiary referral center and the Acoustic Neuroma Association. SUBJECTS AND METHODS Adult patients with VS who completed the Penn Acoustic Neuroma Quality of Life (PANQOL) survey. Patients were classified by treatment at the most recent survey as microsurgery, radiosurgery, observation, or recently diagnosed (RD). PANQOL scores were compared among VS treatment groups and with nontumor controls using analysis of covariance. RESULTS A total of 1362 respondents with VS were analyzed. Total PANQOL scores differed significantly by treatment (P = .024) with adjusted means of 60, 63, 65, and 62 for the microsurgery, radiosurgery, observation, and RD groups, respectively. Subdomain scores for facial function, balance, hearing loss, and pain differed significantly (P < .05) by treatment. Comparisons that surpassed thresholds for clinical significance included microsurgery compared to radiosurgery and observation for facial function, microsurgery compared to observation and RD for hearing loss, and microsurgery compared to radiosurgery and observation for pain. Subdomain scores for anxiety, facial function, balance, hearing loss, energy, and pain and total PANQOL scores for nontumor controls were significantly higher (ie, more favorable) compared to the VS groups (P < .05). General health scores did not differ significantly between the nontumor controls and the VS groups (P = .19). CONCLUSION Differences in HRQOL among treatment modalities are small and variably exceed the minimal clinically important difference. The impact of a VS diagnosis on HRQOL supersedes that of the treatment type.

Abstract
OBJECTIVE Little is known about the long term (greater than 10 years) quality of life in patients with vestibular schwannoma. This study aimed to evaluate long-term outcomes in patients with vestibular schwannoma. METHOD A retrospective cohort study was performed across 2 academic institutions, with patients followed at least 10 years after vestibular schwannoma surgery (2000 to 2007). Telephone interviews were used to assess quality of life using the Glasgow Benefit Inventory and short form 12 item (version 2) health survey. RESULTS A total of 99 out of 110 patients were included. Increasing age and symptom burden were associated with poorer quality of life (p = 0.01 and 0.02, respectively). The presence of imbalance, headache and facial nerve dysfunction were all associated with poorer quality of life scores (p = 0.01, 0.04 and 0.02, respectively). CONCLUSION Identifying and managing post-operative symptoms may improve quality of life in vestibular schwannoma patients and can guide clinical decision making.

Abstract
Objective The main purpose of this article is to determine if vestibular schwannoma consistency as determined by tissue intensity on T2-weighted magnetic resonance imagings (MRIs) is predictive of intraoperative experience and postoperative clinical outcomes. Study Design Retrospective chart review. Setting Tertiary referral center. Patients Seventy-seven patients diagnosed with vestibular schwannomas who were treated with microsurgical resection. Intervention Diagnostic. Main Outcome Measures Intraoperative measures include totality of resection, surgical time and cranial nerve VII stimulation and postoperative measures include House-Brackmann grade and perioperative complications. Results Tumor consistency determined via tissue intensity on MRI was only found to correlate with surgical time, with a softer tumor being associated with a longer surgical time ( p < 0.0001). However, this was primarily driven by tumor volume with larger tumors being associated with longer surgical time based on multivariate analysis. None of the other intraoperative or postoperative measures considered were found to correlate with tumor consistency. Conclusions Tumor consistency determined by MRI is not predictive of intraoperative experience or postoperative outcomes in vestibular schwannomas. Tumor volume is the strongest driver of these outcome measures as opposed to tumor consistency.

Abstract
OBJECTIVE To evaluate the impact of different management options on health-related quality of life (HRQoL) in vestibular schwannoma patients. DATA SOURCES A systematic search of the Cochrane Database, Database of Abstracts of Reviews of Effectiveness, and the Ovid Medline & EMBASE was performed. English and German language studies published between 1980 and 2015 were considered. STUDY SELECTION This is a systematic review of HRQoL of patients managed for vestibular schwannoma. Studies in which HRQoL after one management option were evaluated or compared with other managements or with control populations using validated or reliable questionnaires, were included. DATA EXTRACTION The included studies were independently evaluated by two reviewers. The quality of studies was assessed and graded as per Oxford Centre of Evidence Based Medicine System. RESULTS Ten prospective and 29 retrospective studies were identified: microsurgery initially exerted a negative effect on HRQoL but this tended to improve with follow up. Radiotherapy had a less negative effect but with minimal change over follow up. A significant limitation was that studies did not present results stratified by tumor size. Many patients will need active treatment despite the potential for negative effects on their QoL. The concept of a minimal clinically important difference has been introduced into this field and was compared with five studies. CONCLUSION A number of prospective studies are available but none yet with a disease-specific questionnaire. Heterogeneity and the methodological weaknesses of the included studies constitute the principle limitation of this review. The introduction of the minimal clinically important difference should improve the relevance of studies and allow a sensitive comparison of treatments.

Abstract
BACKGROUND Patients with vestibular schwannoma (VS) often complain about tiredness, exhaustion, lack of energy, and strength, but such symptoms of fatigue have scarcely been objectified and analyzed in a VS population. We aimed to characterize fatigue in a cohort of patients with VS and compare such symptoms with a control group. METHODS All patients who attended an educational course for patients with VS were surveyed with validated tools for assessment of fatigue (fatigue severity scale), anxiety and depression (hospital anxiety and depression scale), sleepiness (Epworth sleepiness scale), and apathy (Starkstein apathy scale). Quality of Life was assessed with the disease-specific Penn Acoustic Neuroma Quality of Life (PANQOL). Symptom severity was estimated with a visual analog scale (VAS). The results have been compared to a control group consisting of patient companions. RESULTS Data from 88 VS patients and 49 controls were analyzed. The controls had similar age and sex distribution as patients. Fifty-seven percent of VS patients had significant fatigue, compared to 25% in the control group. The mean fatigue score was 4.1 for the patients, and 2.8 for controls. Patients with fatigue were more likely to have depression, anxiety, sleepiness, and apathy. No correlation of fatigue was found with age, gender, or treatment modality. Regression analyses revealed depression, apathy, and vertigo to be predictors of fatigue. Fatigue was strongly correlated to QoL. CONCLUSION Almost six out of ten VS patients had fatigue, significantly higher than the control group. Interest and focus on fatigue in VS patients can improve the patient's QoL.

Abstract
Disregarding the widely used division of skull base into anterior and lateral, since the skull base should be conceived as a single anatomic structure, it was to our convenience to group all those approaches that run from the antero-lateral, pure lateral and postero-lateral side of the skull base as “Surgery of the lateral skull base”. “50 years of endeavour” points to the great effort which has been made over the last decades, when more and more difficult surgeries were performed by reducing morbidity. The principle of lateral skull base surgery, “remove skull base bone to approach the base itself and the adjacent sites of the endo-esocranium”, was then combined with function preservation and with tailoring surgery to the pathology. The concept that histology dictates the extent of resection, balancing the intrinsic morbidity of each approach was the object of the first section of the present report. The main surgical approaches were described in the second section and were conceived not as a step-by-step description of technique, but as the highlighthening of the surgical principles. The third section was centered on open issues related to the tumor and its treatment. The topic of vestibular schwannoma was investigated with the current debate on observation, hearing preservation surgery, hearing rehabilitation, radiotherapy and the recent efforts to detect biological markers able to predict tumor growth. Jugular foramen paragangliomas were treated in the frame of radical or partial surgery, radiotherapy, partial “tailored” surgery and observation. Surgery on meningioma was debated from the point of view of the neurosurgeon and of the otologist. Endolymphatic sac tumors and malignant tumors of the external auditory canal were also treated, as well as chordomas, chondrosarcomas and petrous bone cholesteatomas. Finally, the fourth section focused on free-choice topics which were assigned to aknowledged experts. The aim of this work was attempting to report the state of the art of the lateral skull base surgery after 50 years of hard work and, above all, to raise questions on those issues which still need an answer, as to allow progress in knowledge through sharing of various experiences. At the end of the reading, if more doubts remain rather than certainties, the aim of this work will probably be achieved.

Abstract
Abstract
BACKGROUND
The diagnosis of vestibular schwannomas (VS) is associated with reduced patient quality of life (QOL). Minimal clinically important difference (MCID) was introduced as the lowest improvement in a patient-reported outcome (PRO) score discerned as significant by the patient. We formerly presented an MCID for the Penn Acoustic Neuroma QOL (PANQOL) battery based on cross-sectional data from 2 tertiary referral centers.
OBJECTIVE
To validate the PANQOL MCID values using prospective data.
METHODS
A prospective registry capturing QOL was queried, comprising patients treated at the authors’ institution and Acoustic Neuroma Association members. Anchor- and distribution-based techniques were utilized to determine the MCID for domain and total scores. We only included anchors with Spearman's correlation coefficient larger than 0.3 in the MCID threshold calculations. Most domains had multiple anchors with which to estimate the MCID.
RESULTS
A total of 1254 patients (mean age: 57.4 yr, 65% females) were analyzed. Anchor-based methods produced a span of MCID values (median, 25th-75th percentile) for each PANQOL domain and the total score: hearing (13.1, 13-16 points), balance (14, 14-19 points), pain (21, 20-28 points), face (25, 16-36 points), energy (16, 15-18 points), anxiety (16 [1 estimate]), general (13 [1 estimate]), and total (12.5, 10-15 points).
CONCLUSION
Current findings corroborate our formerly shared experience using multi-institutional, cross-sectional information. These MCID thresholds can serve as a pertinent outcome when deciphering the clinical magnitude of VS QOL endpoints in cross-sectional and longitudinal studies.

Abstract
OBJECTIVE The aim of this study was to compare quality of life (QOL) in small unilateral vestibular schwannoma (VS) patients managed by microsurgery, radiotherapy or observation. STUDY DESIGN A retrospective chart review. METHODS The study included a total of 142 patients with VS stage 1 or 2 according to the Koos classification and treated between January 2004 and December 2015. Microsurgery, radiotherapy and observation groups comprised 43, 46 and 53 patients, respectively. All patients completed four QOL (questionnaires: Short-Form Health Survey 36, Hearing Handicap Inventory, Tinnitus Handicap Inventory and Dizziness Handicap Inventory Short-Form). Clinical symptoms and QOL were compared among groups. RESULTS The average time interval between management and filling in the questionnaires was 66 months. There was no difference in QOL between the three groups on any of the four questionnaires. The most debilitating symptom was vertigo for all three groups. Tinnitus was a pejorative factor in the surgery group. Hearing level was deteriorated after microsurgery but there was no significant difference between the radiotherapy group and the middle fossa approach. CONCLUSION Patients with small VS stage 1 and 2 had similar QOL, irrespective of management by observation, radiotherapy or microsurgery. The overall predictor for long-term reduced QOL was vertigo. Vestibular rehabilitation could improve QOL in symptomatic patients.

Abstract
OBJECTIVE To assess postoperative quality of life (QOL) and other patient-reported outcomes following surgery for vestibular schwannoma. STUDY DESIGN Cross-sectional retrospective case review using postal questionnaires. SETTING Tertiary referral center. PATIENTS Five hundred consecutive patients undergoing surgery for vestibular schwannoma. INTERVENTION(S) Patients undergoing surgery via the translabyrinthine approach (excluding neurofibromatosis type 2) under the senior author, with a minimum of 5 years follow-up, were included. MAIN OUTCOME MEASURE(S) QOL was assessed using the Short Form 36 (SF-36) questionnaire and a disease-specific survey to assess patients' subjective outcomes. RESULTS The SF-36 scores in this group were significantly lower than the general UK population, though 24% of respondents reported a subjective improvement in overall QOL. Tumors larger than 4 cm were related to a reduced SF-36 total mental component score (p = 0.037). Increased age at time of surgery correlated with a reduced physical component of QOL (correlation coefficient = -0.26) and an improved mental component (correlation coefficient = 0.26). Subjective reports of postoperative symptoms and return to work, driving and social activities were similar to other published studies. 35% of patients reported vivid dreams or nightmares following surgery; the first reported incidence of this phenomenon in a large group of vestibular schwannoma patients. CONCLUSIONS Generic measures of QOL in patients following translabyrinthine surgery for vestibular schwannoma do not always match subjective reports, reflecting the complexity of QOL assessment and the range of outcomes in this group. Increased time since surgery appears to be associated with an improvement in mental health.

Abstract
Objective To assess the decision-making process of patients with vestibular schwannoma (VS). Study Design Patients with VS completed a voluntary survey over a 3-month period. Setting Surveys were distributed online through email, Facebook, and member website. Subjects and Methods All patients had a diagnosis of VS and were members of the Acoustic Neuroma Association (ANA). A total of 789 patients completed the online survey. Results Of the 789 participants, 474 (60%) cited physician recommendation as a significant influential factor in deciding treatment. In our sample, 629 (80%) saw multiple VS specialists and 410 (52%) sought second opinions within the same specialty. Of those who received multiple consults, 242 (59%) of patients reported receiving different opinions regarding treatment. Those undergoing observation spent significantly less time with the physician (41 minutes) compared to surgery (68 minutes) and radiation (60 minutes) patients ( P < .001). A total of 32 (4%) patients stated the physician alone made the decision for treatment, and 29 (4%) felt they did not understand all possible treatment options before final decision was made. Of the 414 patients who underwent surgery, 66 (16%) felt they were pressured by the surgeon to choose surgical treatment. Conclusion Deciding on a proper VS treatment for patients can be complicated and dependent on numerous clinical and individual factors. It is clear that many patients find it important to seek second opinions from other specialties. Moreover, second opinions within the same specialty are common, and the number of neurotologists consulted correlated with higher decision satisfaction.

Abstract
OBJECTIVE A 'wait and see' strategy is an option when managing patients with small vestibular schwannomas (VS). A risk of growth and worsening of hearing may influence a patient's daily quality of life (QOL). Therefore, the present study focused on QOL parameters in patients who are on a 'wait and see' strategy following magnetic resonance imaging (MRI)-based diagnosis of small unilateral VS. PATIENTS AND METHODS Sixty-five patients (mean age 64.4 years; male:female, 32:33) who suffered from a small unilateral VS (9.34 mm, range 1.5-23 mm) between 2013 and 2016 were included in a prospective single center study. During follow-up, in addition to clinical and neurological examinations and MRI imaging, all patients answered the Short Form 36 questionnaire once to characterize QOL. Additionally, the severity of tinnitus was determined by the Mini-TQ-12 from Hiller and Goebel. RESULTS It was found during follow-up that there was no lowering of QOL in patients with small VS who were on 'wait and see' strategy compared with Germany's general population and no tumor growth was detected in 53 patients (81.5%). Patients with a tumor diameter larger than 10 mm did not suffer from stronger tinnitus, vertigo or unsteadiness than the group with an average tumor size, which is smaller than 10 mm. Sixty-two patients (95.4%) showed ipsilateral hearing loss and three of these reported deafness (4.6%). Severe vertigo or tinnitus is connected with lower levels of mental component scale and physical component scale. These findings reduced the QOL (p = 0.05). CONCLUSION In our series, QOL is not influenced in patients with unilateral untreated small VS in comparison to Germany's general population. This is helpful information when advising patients during follow-up and finding out the optimal timing of individual treatment.

Abstract
BACKGROUND Vestibular schwannoma (VS) is a disease which might affect health-related quality of life (HR-QOL) in a negative manner. For many years, only generic quality of life instruments such as SF-36 were available to measure HR-QOL. However, some years ago, the Penn Acoustic Neuroma Quality Of Life (PANQOL) tool, a disease-specific instrument, was developed and validated. It is expected that the application of this instrument will be able to better assess relevant aspects of the HR-QOL of VS patients in the future. A validated German version of the instrument does not exist yet. The disease-specific symptoms most frequently named by patients are headache and dizziness. RESULTS AND DISCUSSION The available literature shows that the therapeutic approaches affect HR-QOL differently. In particular, radiation therapy of small and medium-sized tumors has no pronounced negative effects on HR-QOL. However, restrictions after surgery become similar to those after radiotherapy over the course of several years. For large VS with a diameter >3 cm, no guiding data on this aspect are currently available. To clarify the outstanding issues, future prospective studies with long-term follow-up of 10 years and more are desirable.

Abstract
OBJECTIVE The management of vestibular schwannoma (VS) remains controversial. One commonly cited advantage of microsurgery over other treatment modalities is that tumor removal provides the greatest chance of long-term cure. However, there are very few publications with long-term follow-up to support this assertion. The purpose of the current study is to report the very long-term risk of recurrence among a large historical cohort of patients who underwent microsurgical resection. METHODS The authors retrospectively reviewed the medical records of patients who had undergone primary microsurgical resection of unilateral VS via a retrosigmoid approach performed by a single neurosurgeon-neurotologist team between January 1980 and December 1999. Complete tumor removal was designated gross-total resection (GTR), and anything less than complete removal was designated subtotal resection (STR). The primary end point was radiological recurrence-free survival. Time-to-event analyses were performed to identify factors associated with recurrence. RESULTS Four hundred fourteen patients met the study inclusion criteria and were analyzed. Overall, 67 patients experienced recurrence at a median of 6.9 years following resection (IQR 3.9-12.1, range 1.2-22.5 years). Estimated recurrence-free survival rates at 5, 10, 15, and 20 years following resection were 93% (95% CI 91-96, 248 patients still at risk), 78% (72-85, 88), 68% (60-77, 47), and 51% (41-64, 22), respectively. The strongest predictor of recurrence was extent of resection, with patients who underwent STR having a nearly 11-fold greater risk of recurrence than the patients treated with GTR (HR 10.55, p < 0.001). Among the 18 patients treated with STR, 15 experienced recurrence at a median of 2.7 years following resection (IQR 1.9-8.9, range 1.2-18.7). Estimated recurrence-free survival rates at 5, 10, 15, and 20 years following GTR were 96% (95% CI 93-98, 241 patients still at risk), 82% (77-89, 86), 73% (65-81, 46), and 56% (45-70, 22), respectively. Estimated recurrence-free survival rates at 5, 10, and 15 years following STR were 47% (95% CI 28-78, 7 patients still at risk), 17% (5-55, 2), and 8% (1-52, 1), respectively. CONCLUSIONS Long-term surveillance is required following microsurgical resection of VS even after GTR. Subtotal resection alone should not be considered a definitive long-term cure. These data emphasize the importance of long-term follow-up when reporting tumor control outcomes for VS.

Abstract
OBJECTIVE To assess the quality of life (QoL) in a representative sample of patients with vestibular schwannoma and to ascertain the differences in outcomes associated with distinct management strategies. PATIENTS AND METHODS Patients with vestibular schwannoma attending a tertiary referral center were asked to complete the Functional Assessment of Chronic Illness Therapy-Brain Questionnaire, which assesses QoL in 5 domains: physical, social, emotional and functional, and a brain cancer-specific domain. Results were analyzed in the overall cohort and in surgery, stereotactic radiosurgery, and conservative management subgroups. The relationship between patient clinical characteristics and QoL outcome also was analyzed by univariable and multivariable logistic regression. RESULTS There were 83 survey respondents with an average age of participants of 57 years and a mean follow-up of 4.9 years. QoL was statistically significantly lower in the surgery subgroup within the Physical QoL domain (P = 0.039); however, there was no significant difference in overall QoL between the 3 subgroups of surgery, radiosurgery, and conservative management (P = 0.17). A poor QoL outcome was associated with the number of symptoms at diagnosis, greater tumor size, and a surgical management strategy. CONCLUSIONS The QoL within this patient cohort was extremely variable in each management group, mirroring the heterogeneous natural history of this disease process. QoL in patients with vestibular schwannoma cannot be predicted based on management strategy alone, but a poor QoL outcome is more likely in patients with larger, symptomatic tumors that are treated surgically.

Abstract
Objective In vestibular schwannoma treatment, the choice among treatment modalities is controversial. The first aim of this study was to examine the quality of life of patients with vestibular schwannoma having undergone observation, radiation therapy, or microsurgical resection. The second aim was to examine the relationship between perceived symptoms and quality of life. Last, the association between quality of life and time since treatment was studied. Study Design Cross-sectional study. Setting Tertiary referral center. Subjects and Methods A total of 1208 patients treated for sporadic vestibular schwannoma between 2004 and 2014 were mailed the disease-specific Penn Acoustic Neuroma Quality of Life (PANQOL) questionnaire and additional questions on symptoms associated with vestibular schwannoma. Total and domain scores were calculated and compared among treatment groups. Propensity scores were used, and results were stratified according to tumor size to control for potential confounders. Correlations were calculated to examine the relationship between self-reported symptoms and quality of life, as well as between quality of life and time since treatment. Results Patients with small tumors (≤10 mm) under observation showed a higher PANQOL score when compared with the radiation therapy and microsurgical resection groups. A strong negative correlation was found between self-reported symptoms and quality of life, with balance problems and vertigo having the largest impact. No correlation was found between PANQOL score and time since treatment. Conclusion This study suggests that patients with small vestibular schwannomas experience better quality of life when managed with observation than do patients who have undergone active treatment.

Lins L, Carvalho FM. SF-36 total score as a single measure of health-related quality of life: Scoping review. SAGE Open Med 2016; 4:2050312116671725. [PMID: 27757230 PMCID: PMC5052926 DOI: 10.1177/2050312116671725] [Citation(s) in RCA: 515] [Impact Index Per Article: 64.4] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/21/2016] [Accepted: 08/10/2016] [Indexed: 12/12/2022] Open
Abstract
According to the 36-Item Short Form Health Survey questionnaire developers, a global measure of health-related quality of life such as the “SF-36 Total/Global/Overall Score” cannot be generated from the questionnaire. However, studies keep on reporting such measure. This study aimed to evaluate the frequency and to describe some characteristics of articles reporting the SF-36 Total/Global/Overall Score in the scientific literature. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses method was adapted to a scoping review. We performed searches in PubMed, Web of Science, SCOPUS, BVS, and Cochrane Library databases for articles using such scores. We found 172 articles published between 1997 and 2015; 110 (64.0%) of them were published from 2010 onwards; 30.0% appeared in journals with Impact Factor 3.00 or greater. Overall, 129 (75.0%) out of the 172 studies did not specify the method for calculating the “SF-36 Total Score”; 13 studies did not specify their methods but referred to the SF-36 developers’ studies or others; and 30 articles used different strategies for calculating such score, the most frequent being arithmetic averaging of the eight SF-36 domains scores. We concluded that the “SF-36 Total/Global/Overall Score” has been increasingly reported in the scientific literature. Researchers should be aware of this procedure and of its possible impacts upon human health.

Abstract
BACKGROUND Vestibular schwannomas are slow growing, benign tumors. There are three possible management options: surgery, radiation treatment or active surveillance. The aim of this study was to assess the general outcome and risk of tumor recurrence. MATERIALS AND METHODS The study included 220 consecutive patients (134 women, 86 men; the age ranged from 18 to 74) operated with the retrosigmoid transmeatal approach. The largest extrameatal diameter of the tumor ranged from 8 to 72mm (mean 30mm). According to the Samii grading scale, the tumors were classified as follows: T2-12 (6%), T3-51 (23%) and T4-157 (71%). Gross total resection was performed in 217 patients and neartotal in 3. RESULTS Two hundred and eighteen (99.1%) patients were discharged home in a satisfactory neurological condition (GR or MD in GOS). One (0.5%) patient died due to brainstem infarction. One (0.5%) patient had unchanged severe cerebellar syndrome in comparison to the preoperative period (SD in GOS). In long-term follow-up, one patient went blind within a few months after surgery. Including the results of further neurosurgical procedures for CSF leak, shunt implantation, tumor regrowth and facial nerve reanimation, 98.6% of the patients were fully independent but with different neurological deficits. Tumor recurrence was observed in 5 (2.3%) patients during the follow-up period (mean term: 6.4 years). The average time to recurrence diagnosis was 8.8 years. All those patients were operated on again without any adjuvant therapy and there was no further re-growth at mean follow-up of 5.2 years. CONCLUSIONS Complete removal of VS is usually curative and poses very low risks of severe disability (if audio-facial sequels are not included), mortality and long-term recurrence. For recurrent tumors, carefully tailored revision surgery without irradiation offers a high efficacy with low risk of complications.

Abstract
BACKGROUND The management of vestibular schwannoma is still a quite controversial issue and can include wait and see policy, surgery and radiotherapy, mainly with stereotactic technique. The purpose of this study is to review the results of recent clinical series treated by radiotherapy. MATERIALS AND METHODS Literature search was performed by Pubmed and Scopus by using the words "vestibular schwannoma, acoustic neuroma, radiotherapy, radiosurgery". RESULTS Management options of VS include wait and see, surgery and radiotherapy. In case of small lesions, literature data report local control rates higher than 90% after radiosurgery (SRS) similar those of surgical techniques. Recent literature reviews show favourable functional outcome by using SRS. Several literature data support the use of fractionated stereotactic radiotherapy (FSRT) in case of large inoperable lesions. CONCLUSION Radiotherapy plays a relevant role in the treatment of VS. In small-size lesions, SRS can guarantee similar local control and potentially better function outcome compared to surgery. In case of large and irregularly shaped lesions, FSRT can be the used when surgery is not feasible.

Abstract
OBJECTIVE To characterize the evolving management of vestibular schwannoma (VS) in the United States. STUDY DESIGN Retrospective analysis of the Surveillance, Epidemiology, and End Results (SEER) database. SETTING SEER database. SUBJECTS AND METHODS All patients with a diagnosis of VS were analyzed. Data were described and compared using trend analyses and univariate and multivariable logistic regression. RESULTS A total of 8330 patients (average age 54.7 years, 51.9% female) were analyzed. The mean incidence was approximately 1.1 per 100,000 per year and did not vary significantly across time; however, from 2004 to 2011, there was a statistically significant decrease in tumor size category at time of diagnosis (P < .01). Overall, 3982 patients (48%) received primary microsurgery, 1978 (24%) radiation therapy alone, and 2370 (29%) observation. Within the microsurgical cohort, 732 (18%) underwent subtotal resection, and of those, 98 (13.4%) received postoperative radiation therapy. Multivariable regression revealed that surgical treatment was more common in younger patients and larger tumor size categories (P < .05). Management trend analysis revealed that microsurgery was used less frequently over time (P < .0001), observation was used more frequently (P < .0001), and the pattern of radiation therapy remained unchanged. Linear regression was used to create an equation that was applied to predict future management practices. These data predict that by 2026, half of all cases of VS will be managed initially with observation. CONCLUSION While the incidence of VS has remained steady, tumor size at time of diagnosis has decreased over time. Within the United States there has been a clear, recent evolution in management toward observation.

Abstract
Objective Several studies have demonstrated small but statistically significant differences in quality-of-life (QOL) scores among vestibular schwannoma (VS) treatment modalities. However, does a several-point difference on a 100-point scale really matter? The minimal clinically important difference (MCID)—defined as the smallest difference in scores that patients perceive as important and that could lead to a change in management—was developed to answer this important question. While the MCID has been determined for QOL measures used in other diseases, it remains undefined in the VS literature. Study Design Distribution- and anchor-based techniques were utilized to define the MCID for the Penn Acoustic Neuroma Quality of Life (PANQOL) and 36-Item Short Form Health Survey (SF-36). Setting Two academic referral centers. Patients Patients with VS (N = 538). Intervention Cross-sectional postal survey. Main Outcome Measures MCID for PANQOL domains and total score and SF-36 Physical and Mental Health Component Summary scores. Results The MCID (median, interquartile range) for the PANQOL total score was 11 points (10-12); the MCIDs for individual domains were as follows: hearing, 6 (5-8); balance, 16 (14-19); facial, 10 (no interquartile range); pain, 11 (10-13); energy, 13 (10-17); anxiety, 11 (5-22); and general, 15 (11-19). The MCID was 7 points (6-11) for the SF-36 Mental Health Component Summary score and 8 points (6-10) for the Physical Health Component Summary score. Conclusions The MCIDs determined in the current study generally exceed differences reported in previous prospective studies, in which conclusions about QOL benefit (or harm) among VS treatment modalities were based on statistical significance alone. Moving forward, these MCIDs should be considered when interpreting results of VS QOL studies.
