Quality of life in patients with intracranial tumors: does tumor laterality matter?

Glioblastomas at the white matter of temporo-parietal junction cause a poor postoperative independence level

INTRODUCTION

Right cerebral hemispheric glioblastomas (GBMs) often decrease the Karnofsky performance status (KPS) score postoperatively, despite the patient having sufficient patient function while performing daily living. This study aimed to evaluate the factors that could cause poor KPS scores during the postoperative chronic phase in patients with right cerebral hemispheric GBMs.

METHODS

Data of 47 patients with newly diagnosed right cerebral hemispheric GBMs were analyzed. All patients were assessed preoperatively and 3 months postoperatively to determine KPS and brain function. To determine tumor location related to the postoperative KPS scores, we used voxel-based lesion symptom mapping (VLSM). The patients were divided into two groups (involvement and non-involvement groups) based on whether their lesion involved a significant region identified by VLSM. We then compared functional factors and prognosis between the groups using the chi-squared and log-rank tests, respectively.

RESULTS

The KPS score significantly decreased after surgery compared to that preoperatively measured (p = 0.023). VLSM revealed that tumors in the white matter of temporo-parietal junction (WM-TPJ) caused a significant decline in the KPS score at three months postoperatively. The patients in the involvement group had a higher probability of impaired attention, visuospatial cognition, emotion recognition, and visual field than did those in the non-involvement group. In addition, tumor in the WM-TPJ were associated with shorter progression-free survival and overall survival (p = 0.039 and 0.023, respectively).

CONCLUSIONS

GBMs involving the right WM-TPJ are more likely to result in poor postoperative KPS scores and prognoses. Impairments of several kinds of brain functions caused by tumor invasion to the WM-TPJ may be associated with lower KPS scores.

Surgical Site Infections in Glioblastoma Patients-A Retrospective Analysis

Surgical site infections (SSIs) after craniotomy lead to additional morbidity and mortality for patients, which are related to higher costs for the healthcare system. Furthermore, SSIs are associated with a longer hospital stay for the patient, which is particularly detrimental in glioblastoma patients due to their limited life expectancy. Risk factors for SSIs have already been described for craniotomies in general. However, there is limited data available for glioblastoma patients. As postoperative radiation influences wound healing, very early radiation is suspected to be a risk factor for SSI. Nevertheless, there are no data on the optimal timing of radiotherapy. To define risk factors for these patients, we analyzed our collective. We performed a retrospective analysis of all operations with histological evidence of a glioblastoma between 2012 and 2021. Open biopsy and tumor removal (gross total resection, subtotal resection) were included. Stereotactic biopsies were excluded. Demographic data such as age and gender, as well as duration of surgery, diameter of the trepanation, postoperative radiation with interval, postoperative chemotherapy, highest blood glucose level, previous surgery, ASA score, foreign material introduced, subgaleal suction drainage, ventricle opening and length of hospital stay, were recorded. The need for surgical revision due to infection was registered as an SSI. A total of 177 patients were included, of which 14 patients (7.9%) suffered an SSI. These occurred after a median of 45 days. The group with SSIs tended to include more men (57.1%, p = 0.163) and more pre-operated patients (50%, p = 0.125). In addition, foreign material and subgaleal suction drains had been implanted more frequently and the ventricles had been opened more frequently, without reaching statistical significance. Surprisingly, significantly more patients without SSIs had been irradiated (80.3%, p = 0.03). The results enable a better risk assessment of SSIs in glioblastoma patients. Patients with previous surgery, introduced foreign material, subgaleal suction drain and opening of the ventricle may have a slightly higher for SSIs. However, because none of these factors were significant, we should not call them risk factors. A less radical approach to surgery potentially involving these factors is not justified. The postulated negative role of irradiation was not confirmed, hence a rapid chemoradiation should be induced to achieve the best possible oncologic outcome.

Surveillance, Epidemiology, and End Results database and propensity score matching analysis of postoperative radiotherapy for non-malignant meningioma: A retrospective cohort study

BACKGROUND

The clinical effect of postoperative radiotherapy (PORT) in non-malignant meningioma (NMM) has not been well explored.

METHODS

A total of 8629 patients with NMM (surgery alone group: n = 7716, postoperative radiotherapy group: n = 913) were obtained from the Surveillance, Epidemiology, and End Results database. Patient profiles were matched by 1:1 propensity score matching (PSM). Logistic regression analysis was performed to identify factors associated with PORT versus surgery alone (SA). Univariate and multivariate Cox regression analyses determined prognostic variables with overall survival (OS) in NMM. Subgroup analyses were performed with Cox proportional hazards regression models.

RESULTS

All the SA (n = 7716) and PORT (n = 913) groups were included. Women with PORT (66.3%) and SA (70.9%) were almost twice as likely as men, and tumors with benign behaviors in the SA group were almost seven times more frequent than those with malignant characteristics. We explored the demographic, clinical characteristics, and prognostic factors in NMM. Laterality, surgery, tumor size, diagnosis year, age, and tumor behavior were associated with PORT versus SA. Patients treated with PORT had better OS than those treated with SA (p = 0.03). After PSM, PORT remained comparable to SA (hazard ratio 0.56, 95% confidence interval 0.35-0.88, p = 0.013). In the subgroup analysis of PORT treatment, borderline malignant behavior increased the death risk by 23%, while other variables did not have a significant clinical benefit (p > 0.05).

CONCLUSIONS

Borderline malignant behavior should be considered seriously, and the PORT regimen should be actively implemented for patients with benign meningiomas.

Prognostic model for predicting overall survival in patients with glioblastoma: an analysis based on the SEER database

Predicting the prognosis of glioblastoma (GBM) has always been important for improving survival. An understanding of the prognostic factors for patients with GBM can help guide treatment. Herein, we aimed to construct a prognostic model for predicting overall survival (OS) for patients with GBM. We identified 11,375 patients with pathologically confirmed GBM from the Surveillance, Epidemiology, and End Results database between 2004 and 2015. The 1-, 2-, and 3-year survival probabilities were 48.8%, 22.5%, and 13.1%, respectively. The patients were randomly divided into the training cohort (n = 8531) and the validation cohort (n = 2844). A Cox proportional risk regression model was used to analyze the prognostic factors of patients in the training cohort, and a nomogram was constructed. Then concordance indexes (C-indexes), calibration curves, and receiver operating characteristic (ROC) curves were used to assess the performance of the nomograms by internal (training cohort) and external validation (validation cohort). Log-rank test and univariate analysis showed that age, race, marital status, extent of surgical resection, chemotherapy, and radiation were the prognostic factors for patients with GBM (p < 0.05), which were used to construct nomogram. The C-index of the nomogram was 0.717 (95% confidence interval (CI), 0.710-0.724) in the training cohort, and 0.724 (95% CI, 0.713-0.735) in the validation cohort. The nomogram had a higher areas under the ROC curve value. The nomogram was well validated, which can effectively predict the OS of patients with GBM. Thus, this nomogram could be applied in clinical practice.

The impact of brain lesions on health-related quality of life in patients with WHO CNS grade 3 or 4 glioma: a lesion-function and resting-state fMRI analysis

PURPOSE

In glioma patients, tumor development and multimodality therapy are associated with changes in health-related quality of life (HRQoL). It is largely unknown how different types and locations of tumor- and treatment-related brain lesions, as well as their relationship to white matter tracts and functional brain networks, affect HRQoL.

METHODS

In 121 patients with pretreated gliomas of WHO CNS grades 3 or 4, structural MRI, O-(2-[¹⁸F]fluoroethyl)-L-tyrosine (FET) PET, resting-state functional MRI (rs-fMRI) and self-reported HRQoL questionnaires (EORTC QLQ-C30/BN20) were obtained. Resection cavities, T1-enhancing lesions, T2/FLAIR hyperintensities, and lesions with pathologically increased FET uptake were delineated. Effects of tumor lateralization, involvement of white matter tracts or resting-state network nodes by different types of lesions and within-network rs-fMRI connectivity were analyzed in terms of their interaction with HRQoL scores.

RESULTS

Right hemisphere gliomas were associated with significantly less favorable outcomes in physical, role, emotional and social functioning, compared with left-sided tumors. Most functional HRQoL scores correlated significantly with right-sided white-matter tracts involvement by T2/FLAIR hyperintensities and with loss of within-network functional connectivity of right-sided nodes. Tumors of the left hemisphere caused significantly more communication deficits.

CONCLUSION

In pretreated high-grade gliomas, right hemisphere lesions are associated with reduced HRQoL scores in most functional domains except communication ability, compared to tumors of the left hemisphere. These relationships are mainly observed for T2/FLAIR lesions involving structural and functional networks in the right hemisphere. The data suggest that sparing the right hemisphere from treatment-related tissue damage may improve HRQoL in glioma patients.

Frontal aslant tract in the non-dominant hemisphere: A systematic review of anatomy, functions, and surgical applications

Knowledge of both the spatial organization and functions of white-matter fiber tracts is steadily increasing. We report here the anatomy and functions of the frontal aslant tract (FAT) in the non-dominant hemisphere (usually the right hemisphere). Despite the structural symmetry between the right and left FAT, these two tracts seem to display functional asymmetry, with several brain functions in common, but others, such as visuospatial and social cognition, music processing, shifting attention or working memory, more exclusively associated with the right FAT. Further studies are required to determine whether damage to the right FAT causes permanent cognitive impairment. Such studies will constitute the best means of testing whether this tract is a critical pathway that must be taken into account during neurosurgical procedures and the essential tasks to be incorporated into intraoperative monitoring during awake craniotomy.

Elevated Serum Lactate in Glioma Patients: Associated Factors

Introduction

Serum lactate levels in brain cancer patients correlate with tumor malignancy grading, and serum lactate has been suggested as a potential biomarker and prognostic factor. The purpose of this study was to identify potential sources of elevated serum lactate in patients with brain gliomas by examining factors of importance for serum lactate production and clearance.

Methods

In this cross-sectional study, data were collected from 261 glioma patients who underwent surgery from March 2011 to June 2015. We recorded patient gender, age, blood serum measures of lactate, glucose, pH, hemoglobin and base excess, patient health status, medications, and tumor characteristics. Patients with elevated and normal serum lactate levels were compared, and we explored if there were correlations between the variables. The association of serum lactate with the measured variables was investigated by simple and multivariable linear regression models.

Results and Discussion

Patients with elevated serum lactate had higher blood glucose, larger tumor volumes, and more tumor edema; more often needed pressor medication during surgery; and more often received corticosteroid treatment. The investigated variables were highly correlated. Multivariable linear regression indicated that gender, tumor volume, Charlson Comorbidity Index, hyperglycemia, and corticosteroid treatment were associated with serum lactate levels. Histopathology was not an independent factor. In conclusion, comorbidities, hyperglycemia, and presurgical corticosteroid treatment exhibited the strongest association with serum lactate in glioma patients.

Quality of life and return to work and sports after spinal ependymoma resection

Adult spinal ependymoma presents a rare low-grade tumor entity. Due to its incidence peak in the fourth decade of life, it mostly affects patients during a professionally and physically active time of life. We performed a retrospective monocentric study, including all patients operated upon for spinal ependymoma between 2009 and 2020. We prospectively collected data on professional reintegration, physical activities and quality-of-life parameters using EQ-5D and SF-36. Issues encountered were assessed using existing spinal-cord-specific questionnaires and free-text questions. In total, 65 of 114 patients agreed to participate. Most patients suffered from only mild pre- and postoperative impairment on the modified McCormick scale, but 67% confirmed difficulties performing physical activities in which they previously engaged due to pain, coordination problems and fear of injuries after a median follow-up of 5.4 years. We observed a shift from full- to part-time employment and patients unable to work, independently from tumor dignity, age and neurological function. Despite its benign nature and occurrence of formal only mild neurological deficits, patients described severe difficulties returning to their preoperative physical activity and profession. Clinical scores such as the McCormick grade and muscle strength may not reflect the entire self-perceived impairment appropriately.

A systematic review of the use of subcortical intraoperative electrical stimulation mapping for monitoring of executive deficits and neglect: what is the evidence so far?

BACKGROUND

Over the past decade, the functional importance of white matter pathways has been increasingly acknowledged in neurosurgical planning. A method to directly study anatomo-functional correlations is direct electrical stimulation (DES). DES has been widely accepted by neurosurgeons as a reliable tool to minimize the occurrence of permanent postoperative motor, vision, and language deficits. In recent years, DES has also been used for stimulation mapping of other cognitive functions, such as executive functions and visuospatial awareness.

METHODS

The aim of this review is to summarize the evidence so far from DES studies on subcortical pathways that are involved in visuospatial awareness and in the following three executive functions: (1) inhibitory control, (2) working memory, and (3) cognitive flexibility.

RESULTS

Eleven articles reported on intraoperative electrical stimulation of white matter pathways to map the cognitive functions and explicitly clarified which subcortical tract was stimulated. The results indicate that the right SLF-II is involved in visuospatial awareness, the left SLF-III and possibly the right SLF-I are involved in working memory, and the cingulum is involved in cognitive flexibility.

CONCLUSIONS

We were unable to draw any more specific conclusions, nor unequivocally establish the critical involvement of pathways in executive functions or visuospatial awareness due to the heterogeneity of the study types and methods, and the limited number of studies that assessed these relationships. Possible approaches for future research to obtain converging and more definite evidence for the involvement of pathways in specific cognitive functions are discussed.

Life after surgical resection of a low-grade glioma: A prospective cross-sectional study evaluating health-related quality of life

Health related quality of life (HRQoL) has become an important consideration in LGG patients. We report the largest prospective, longitudinal, cross-sectional cohort study of HRQoL in LGG patients, aiming to identify actionable determinants of HRQoL. Post-operative LGG adults at a large tertiary center underwent HRQoL assessment using the EORTC QLQ-C30 questionnaire administered at follow-up visits and by mail. Scores at 12 month intervals were compared with those from a normative reference population. Spearman's Rho was used to evaluate correlation of subdomain and symptom scores with global HRQoL and change over time. There were 167 participants and 366 questionnaires analysed. Patients reported reduced global HRQoL at nearly every 12 month interval with significant impairments at 12, 72, 108, and 120+ months postoperative. They also reported a significant impairment in each functional subdomain at 12 months, which persisted to varying degrees over 120 months, as did significant fatigue and insomnia. Role, emotional, and social subdomains, as well as fatigue, were significantly associated with global HRQoL at the first 12 month interval. Overall, there was no significant correlation between time from surgery and global HRQoL or the subdomain functional or symptom sections of the QLQ-C30. LGG patients report considerable, sustained impairments in HRQoL after surgery, particularly in cognitive, emotional, and social function, as well as suffering significant fatigue and insomnia. These are strongly associated with global HRQoL and thus can be considered determinants of global HRQoL that with intervention, may improve HRQoL for our LGG patients. This is the largest prospective longitudinal study of HRQoL in postoperative LGG patients yet reported and is ongoing. It identifies several determinants of impaired HRQoL with available management options and interventions that have the potential to significantly improve HRQoL in these patients.

Awake surgery for right frontal lobe glioma can preserve visuospatial cognition and spatial working memory

PURPOSE

Awake surgery is the standard treatment to preserve motor and language functions. This longitudinal study aimed to evaluate the resection rate and preservation of neurocognitive functions in patients with right frontal lobe glioma who underwent awake surgery.

METHODS

Thirty-three patients (mean age, 48.0 years) with right frontal lobe glioma who underwent awake surgery at our hospital between 2013 and 2019 were included. Fourteen, thirteen, and six cases had WHO classification grades of II, III, and IV, respectively. We evaluated visuospatial cognition (VSC) and spatial working memory (SWM) before and three months after surgery. Relevant brain areas for VSC and SWM were intraoperatively mapped, whenever the task was successfully accomplished. Therefore, patients were divided into an intraoperative evaluation group and a non-evaluation group for each function, and the resection rate and functional outcomes were compared.

RESULTS

The removal rate in the evaluation group for VSC and SWM were similar to that in the non-evaluation group. Chronic impairment rate of VSC was significantly lower in the evaluation than in the non-evaluation group (5.6% vs. 33.3%, p = 0.034). No patient showed postoperative SWM impairment in the evaluation group as opposed to the non-evaluation group (16.7%, p = 0.049). The probability of resection of the deeper posterior part of the middle frontal gyrus, the relevant area of VSC, was higher in the non-evaluation group than in the evaluation group.

CONCLUSIONS

We statistically verified that awake surgery for right frontal lobe glioma results in successful preservation of VSC and SWM with satisfying resection rates.

Advancements in predicting outcomes in patients with glioma: a surgical perspective

Introduction: Diffuse glioma is a challenging neurosurgical entity. Although surgery does not provide a cure, it may greatly influence survival, brain function, and quality of life. Surgical treatment is by nature highly personalized and outcome prediction is very complex. To engage and succeed in this balancing act it is important to make best use of the information available to the neurosurgeon.Areas covered: This narrative review provides an update on advancements in predicting outcomes in patients with glioma that are relevant to neurosurgeons.Expert opinion: The classical 'gut feeling' is notoriously unreliable and better prediction strategies for patients with glioma are warranted. There are numerous tools readily available for the neurosurgeon in predicting tumor biology and survival. Predicting extent of resection, functional outcome, and quality of life remains difficult. Although machine-learning approaches are currently not readily available in daily clinical practice, there are several ongoing efforts with the use of big data sets that are likely to create new prediction models and refine the existing models.

Effects of Chronic Brain Injury on Quality of Life: A Study in Patients With Left- or Right-Sided Lesion

Objectives

To test the hypothesis that quality of life (QOL) is made up of different components, and each of these has different anatomic and demographic contributors.

Design

Questionnaire-based study.

Setting

Center for Cognitive Neuroscience, University of Pennsylvania.

Participants

People with chronic brain injury (N=52) volunteered for the study. After excluding patients with severe communication deficits, bilateral lesions, and incomplete data, 42 patients with focal lesions were included in the final study: 22 patients with left hemisphere injury (LHI) (9 women and 13 men; mean age ± SD, 60.6±11.2y [range: 36-83]; mean chronicity ± SD, 11.5±4.2y) and 20 patients with right hemisphere injury [RHI] (16 women and 4 men; mean age ± SD [62.7±12.8y] [range: 31-79]; mean chronicity ± SD 10.1±4.3y).

Interventions

Not applicable.

Main Outcome Measures

We administered the RAND36-Item Health Survey (RAND-Version-1.0), Stroke Impact Scale (version 3.0), Positive Affect and Negative Affect Scale, and Distress Thermometer to measure QOL in LHI and RHI patients. Exploratory factor analysis with principal component method reduced these measures to 5 factors, roughly categorized as-(1) physical functioning; (2) general health; (3) emotional health; (4) social functioning; and (5) cognitive functioning. Exploratory analyses attempted to relate these factor scores to demographic variables, neuroanatomical data, and neuropsychological measures.

Results

Physical functioning was the biggest contributor to reduced QOL, explaining 32.5%, of the variance. Older age, less education, and larger lesion size predicted poorer physical functioning (P<.001). Age also affected emotional health. (P=.019). Younger patients reported poorer emotional health than older patients. LHI patients reported less satisfaction with their cognitive functioning (P=.009) and RHI patients with their physical functioning (P=.06). Exploratory neuroanatomical analyses hinted at brain areas that may be associated with the perception of disability in each QOL component.

Conclusions

QOL is composed of 5 components. Clinical and demographic factors appear to differentially affect these aspects of patients' perceived QOL, providing hypotheses for further testing and suggesting potential relations for therapeutic interventions to consider.

Hemispheric tumor location and the impact on health-related quality of life, symptomatology, and functional performance outcomes in patients with glioma: an exploratory cross-sectional study

PURPOSE

To inform high-quality rehabilitation services, this study investigates if patients with glioma located in the right- or left-hemisphere present with different health-related quality of life, symptomatology, and functional performance in the early disease state.

MATERIAL AND METHODS

Between 2013 and 2017, 81 adult patients were assessed during the first week of chemo-radiation, following resection. Patients were stratified into two groups depending on a right- or left-hemispheric lesion. Independent t-tests analyzed potential differences regarding health-related quality of life, symptomatology, and functional performance.

RESULTS

Forty-five patients (56%) had a tumor located in the right hemisphere, whereas 36 patients (44%) had a tumor in the left hemisphere. Except for more patients with tumors in the left hemisphere having their tumor located in eloquent brain areas, the groups were well matched. No group differences were found in health-related quality of life. Group differences were found in communication deficits (Δ-10.9, 95%CI -19.1; -2.3, p = 0.01), which were more frequent in patients with left-sided lesions, and of headaches (Δ13.9, 95%CI 1.8; 25.9, p = 0.02), which were more frequent in patients with right-hemispheric lesions, who also had significantly greater difficulties with process-skills when performing everyday life tasks (Δ-0.3, 95%CI -0.5; -0.1, p < 0.01). Also, weak evidence suggests that patients with Glioblastoma Multiforme located in the right hemisphere are more affected by fatigue compared to their left-hemispheric comparisons (Δ14.6, 95%CI 0.19; 29.0, p < 0.05).

CONCLUSIONS

The hemispheric location of a glial-cell brain tumor has no consequence for health-related quality of life at the beginning of chemo-radiation treatments. However, findings of tumor-location dependent conditions of communication, headache, patients' ability to perform executive functions, and fatigue should be considered in rehabilitation situations when designing an intervention to potentially improve executive functions and relieve the symptoms.Implications for rehabilitationIt is unclear if laterality impact glioma patients health-related quality of life and functional performance, which might implicate differentiated rehabilitation interventions.The hemispheric location of a glial-cell brain tumor has no consequence for the health-related quality of life at the beginning of chemo-radiation, following surgery.Tumor-location dependent conditions of communication, headache, fatigue, and patients' ability to perform executive functions should be considered when designing an intervention to improve executive functions and symptom-relieve.In rehabilitation interventions, tumor laterality is not a factor that needs to be considered before recommending aerobic training to improve the functional capacity of patients with glioma.

Standardization of an Arabic-Language Neuropsychological Battery for Epilepsy Surgical Evaluations

OBJECTIVES

This study provides a standardized Arabic language neuropsychological test battery and tests its ability to distinguish patients with left and right hemisphere epileptic foci who are candidates for surgical resection.

METHODS

An Arabic language battery of 15 tests was developed based on the neuropsychological test battery used at the Johns Hopkins Hospital for surgical evaluation of patients undergoing temporal lobe resection. With modifications where culturally required, 11 tests were translated to Arabic by the principal investigator and back-translated by two bilingual health professionals; four tests were available in Arabic and added to the battery. The battery was administered to 21 Arabic-speaking patients with left temporal epileptic foci, 21 with right temporal epileptic foci, and 46 neurologically and psychiatrically healthy adults.

RESULTS

Nearly all the Arabic test versions were capable of differentiating healthy controls and the temporal lobe epilepsy (TLE) groups. Tests known to distinguish left and right temporal lobectomy candidates, such as wordlist memory and prose recall, were able to do so as accurately as the English versions. Also, a roughly "culturally free" task (the Baltimore Board) and a newly developed version of the Boston Naming Test demonstrated some sensitivity to left temporal lobe involvement.

CONCLUSIONS

Arabic-language neuropsychological tests for epilepsy surgical evaluations are made available, demonstrate cultural sensitivity and clinical validity, and require further psychometric property and normative research. (JINS, 2019, 25, 761-771).

Quality of Life Perception, Cognitive Function, and Psychological Status in a Real-world Population of Glioblastoma Patients Treated With Radiotherapy and Temozolomide: A Single-center Prospective Study

BACKGROUND

Health-related quality of life (HRQoL), cognitive function, and psychological status represent an important focus during the treatment of glioblastoma patients. Nevertheless, few randomized, prospective clinical trials have analyzed these factors, and very little is known in the real-clinical world. We evaluated these characteristics in glioblastoma patients treated with standard first-line therapy outside clinical trials.

PATIENTS AND METHODS

In total, 111 newly, histologically diagnosed glioblastoma patients treated at our oncology center with radiotherapy and temozolomide were prospectively enrolled. No patient was enrolled in an experimental clinical trial. We assessed HRQoL, cognitive function, and psychological status before starting treatment, at the end of radiotherapy, and every 3 months until 9 months after the end of radiotherapy using EORTC QLQ-C30, BN20, MMSE, and HADS questionnaires.

RESULTS

Global health status, physical, cognitive, and social functioning remained unchanged throughout the study period. A statistically significant change was found in emotional functioning as well as a clinically meaningful amelioration in role functioning between the baseline assessment and 9 months after radiotherapy. Patients older than 65 years reported greater impairment on the bladder control scale than younger patients. When considering tumor location, global health status, communication deficit, and drowsiness, scores were significantly different between the right and left hemispheres. Female patients had a clinically relevant lower score for physical functioning at baseline and 3 months after radiation therapy. Female patients also had a clinically relevant lower depression score at 9 months after radiation therapy.

CONCLUSIONS

In routine neurooncology practice, HRQoL, cognitive function, and psychological status did not worsen during first-line treatment in glioblastoma patients receiving standard radiotherapy and temozolomide treatment. However, some patient subgroups, such as elderly and female patients, may have different experiences with treatment, and further investigation is required.

EQ-5D Quality-of-Life Analysis and Cost-Effectiveness After Skull Base Meningioma Resection

BACKGROUND

Skull base meningioma management is complicated by their proximity to intracranial neurovascular structures because complete resection may pose a risk of worsening morbidity.

OBJECTIVE

To assess the influence of clinical outcomes and surgical management on patient-perceived quality-of-life outcomes, value, and cost-effectiveness.

METHODS

Patients who underwent resection of a skull base meningioma, had adequate clinical follow-up, and completed EQ-5D-3L questionnaires preoperatively and at 1 mo and 1 yr postoperatively were identified in a retrospective review. Cost data from the Value Driven Outcomes database were analyzed.

RESULTS

A total of 52 patients (83.0% women, mean age 51.9 yr) were categorized by worsened (n = 7), unchanged (n = 24), or improved (n = 21) EQ-5D-3L index scores at 1-mo follow-up. No difference in subcategory cost contribution or total cost was seen in the 3 groups. Patients with improved scores showed a steady improvement through each follow-up period, whereas those with unchanged or worsened scores did not. Mean quality-adjusted life years (QALYs) and cost per QALY improved for all groups but at a higher rate for patients with better outcomes at 30-d follow-up. Female sex, absence of proptosis, nonfrontotemporal approaches, no optic nerve decompression, and absence of surgical complications demonstrated improved EQ-5D-3L scores at 1-yr follow-up. A mean cost per QALY of $27 731.06 ± 22 050.58 was observed for the whole group and did not significantly differ among patient groups (P = .1)

CONCLUSION

Patients undergoing resection of skull base meningiomas and who experience an immediate improvement in EQ-5D are likely to show continued improvement at 1 yr, with improved QALY and reduced cost per QALY.

The relevant psychological burden of having a benign brain tumor: a prospective study of patients undergoing surgical treatment of cranial meningiomas

OBJECTIVE

Meningiomas are the most common intracranial neoplasm. Evidence concerning surgical management and outcome is abundant, while the implications for the quality of life (QOL) of a patient confronted with the diagnosis and undergoing surgery are unclear. The authors conducted a prospective study to evaluate QOL in relation to psychological comorbidities comorbidities.

METHODS

A prospective study of patients undergoing elective surgery for the removal of an intracranial meningioma was performed. The authors evaluated depression (Allgemeine Depressionsskala K score) and anxiety (Post-Traumatic Stress Scale-10 [PTSS-10]; State Trait Anxiety Inventory-State Anxiety and -Trait Anxiety [STAI-S and STAI-T]; and Anxiety Sensitivity Index-3 [ASI-3]) scores before surgery and at 3 and 12 months after surgery. The correlation between preoperative psychological burden and postoperative QOL as measured by the 36-Item Short Form Health Survey and EQ-5L questionnaires was analyzed. Incidence and influence of these psychiatric comorbidities on clinical outcome were examined.

RESULTS

A total of 78 patients undergoing resection of a meningioma between January 2013 and September 2017 participated in the preoperative psychological screening and 71 patients fully completed postoperative follow-up examination after 1 year of follow-up. At presentation, 48 patients (67.7%) had abnormal anxiety scores, which decreased to 29.6% (p = 0.003). On follow-up at 12 months, mean EQ-5L visual analog scale scores were significantly lower in patients with pathological scores on the PTSS-10 (0.84 vs 0.69; p = 0.004), STAI-S (0.86 vs 0.68; p = 0.001), and STAI-T (0.85 vs 0.71; p = 0.011). Neurological status (modified Rankin Scale) improved slightly and showed some correlation with psychological comorbidities QOL scores (p = 0.167). There was a nonsignificant increase of EQ-5L scores over the period of follow-up (p = 0.174) in the repeated-measures analysis. In the regression analysis, impaired QOL and physical disability on follow-up correlated with elevated preoperative anxiety and depression levels.

CONCLUSIONS

The QOL and physical disability of patients undergoing resection of an intracranial meningioma highly depend on preoperative anxiety and depression levels. Stress and anxiety scores generally decrease after the resection, which leads us to conclude that there is a tremendous emotional burden caused by an upcoming surgery, necessitating close psychooncological support in order to uphold functional outcome and health-related QOL in the postoperative course.

Quality of life after surgery for intracranial meningioma

BACKGROUND

To the authors' knowledge, limited data exist regarding long-term quality of life (QOL) for patients diagnosed with intracranial meningioma.

METHODS

The data in the current study concerned 1722 meningioma cases diagnosed among residents of Connecticut, Massachusetts, California, Texas, and North Carolina from May 1, 2006 through March 14, 2013, and 1622 controls who were frequency matched to the cases by age, sex, and geography. These individuals were participants in a large, population-based, case-control study. Telephone interviews were used to collect data regarding QOL at the time of initial diagnosis or contact, using the Medical Outcomes Study Short-Form 36 Health Survey. QOL outcomes were compared by case/control status.

RESULTS

Patients diagnosed with meningioma reported levels of physical, emotional, and mental health functioning below those reported in a general healthy population. Case participants and controls differed most significantly with regard to the domains of Physical and Social Functioning, Role-Physical, Role-Emotional, and Vitality.

CONCLUSIONS

In the current study, patients with meningioma experienced statistically significant decreases in QOL compared with healthy controls of a similar demographic breakdown, although these differences were found to vary in clinical significance. Cancer 2018;124:161-6. © 2017 American Cancer Society.

The patients' view: impact of the extent of resection, intraoperative imaging, and awake surgery on health-related quality of life in high-grade glioma patients-results of a multicenter cross-sectional study

The objective of the present study is to assess the influence of extent of resection (EoR), use of intraoperative imaging, and awake surgery on health-related quality of life (HRQoL) in high-grade glioma (HGG) patients in a prospective multicenter study. We analyzed 170 surgeries of patients suffering from a HGG. During the first year after resection, HRQoL was evaluated using the European Organization of Research and Treatment of Cancer Core Questionnaire C30 and Brain Neoplasm 20 questionnaires. We assessed the influence of EoR; awake surgery; and use of 5-aminolevulinic acid (5-ALA), intraoperative MRI (iMRI), and their combination on sum scores for function and symptoms as well as several neurological single items. In mixed-model analyses, adjustments for age, Karnofsky performance status (KPS), and eloquent location were performed. In the mixed model, EoR generally did not significantly influence HRQoL (p = 0.10). Yet, patients receiving subtotal resection (STR) vs. patients with biopsy showed significantly better QoL and role and cognitive functions (p = 0.04, p = 0.02, and p < 0.01, respectively). The combination of iMRI and 5-ALA reached the highest EoR (95%) followed by iMRI alone (94%), 5-ALA alone (74%), and no imaging (73%). Thereby, neurological symptoms were lowest and functioning score highest after combined use of iMRI and 5-ALA, without reaching significance (p = 0.59). Despite lower scores in emotional function (59 vs. 46, p = 0.24), no significant impact of awake surgery on HRQoL was found (p = 0.70). In HGG patients, STR compared to biopsy was significantly associated with better HRQoL and fewer neurological symptoms in this series. An escalated use of intraoperative imaging increased EoR with stable or slightly better HRQoL and fewer neurological symptoms. Based on HRQoL, awake surgery was a well-tolerated and safe method in our series.

Is there a response shift in generic health-related quality of life 6 months after glioma surgery?

Background

Patients may recalibrate internal standards when faced with a serious diagnosis or neurological deficits. This so-called response shift is important to understand in longitudinal health-related quality of life (HRQoL) data, but this is not quantitatively assessed in glioma patients.

Methods

Patients with gliomas were eligible for this HRQoL study. We used EuroQol-5D 3 L to assess generic HRQoL with assessment preoperatively and at 6 months postoperatively. At time of follow-up, patients scored how they considered their baseline HRQoL in retrospect using the same questionnaire (“then-test”).

Results

Seventy-three patients were enrolled between January 2013 and September 2015. With the then-test approach, the mean EQ-5D 3 L index was similar compared to baseline (0.77, mean difference 0.01, 95% CI −0.57 to 0.07, p = 0.82). Also, then-test and baseline VAS score were similar (mean difference 0, 95% CI −7 to 7, p = 0.97). However, a 0.10–0.13 difference from baseline was observed in patients that improved or deteriorated in HRQoL at follow-up according to the then-test EQ-5D 3 L index value. The direction of change as observed from the then-test was similar to the direction of clinical change, reducing the impact of any HRQoL change from baseline to follow-up.

Conclusions

On average, we observed no response shift using EQ-5D 3 L in the selection of glioma patients able to participate at 6 months after surgery. However, following change in HRQoL at follow-up, response shift seems to reduce the effects of HRQoL changes by lowering of internal standards in patients that deteriorate and raising the standards in patients that improve.
