Health-Related Quality of Life Outcomes in Meningioma Patients Based upon Tumor Location and Treatment Modality: A Systematic Review and Meta-Analysis

Patients with meningiomas may have reduced health-related quality of life (HRQoL) due to postoperative neurological deficits, cognitive dysfunction, and psychosocial burden. Although advances in surgery and radiotherapy have improved progression-free survival rates, there is limited evidence regarding treatment outcomes on HRQoL. This review examines HRQoL outcomes based on tumor location and treatment modality. A systematic search in PubMed yielded 28 studies with 3167 patients. The mean age was 54.27 years and most patients were female (70.8%). Approximately 78% of meningiomas were located in the skull base (10.8% anterior, 23.3% middle, and 39.7% posterior fossae). Treatment modalities included craniotomy (73.6%), radiotherapy (11.4%), and endoscopic endonasal approach (EEA) (4.0%). The Karnofsky Performance Scale (KPS) was the most commonly utilized HRQoL instrument (27%). Preoperative KPS scores > 80 were associated with increased occurrence of postoperative neurological deficits. A significant difference was found between pre- and post-operative KPS scores for anterior/middle skull base meningiomas (SBMs) in comparison to posterior (SBMs) when treated with craniotomy. Post-craniotomy SF-36 scores were lower for posterior SBMs in comparison to those in the anterior and middle fossae. Risk factors for poor neurological outcomes include a high preoperative KPS score and patients with posterior SBMs may experience a greater burden in HRQoL.

Meningioma WHO I with involvement of the optical structures-does proton therapy lead to changes in quality of life with regard to subjective visual performance?

BACKGROUND

In addition to local tumor control, the aim of any curative radio-oncological treatment is to maintain quality of life. In the treatment of patients with meningioma with a close relationship to optical structures, the preservation of visual performance is a particular challenge. Use of proton therapy can reduce the dose burden to organs at risk immediately adjacent to the tumor. The aim of this study was to score the subjective assessment of visual performance in patients with meningioma involving the optical structures before and after proton therapy.

METHODS

All proton-treated patients with meningioma WHO I whose planning target volumes (PTV) included parts of the optic nerve and/or chiasm were included in this study. Subjective assessment of visual performance was evaluated using the Visual Disorder Scale (VDS) of the EORTC QLQ-BN20 questionnaire. This scale includes values from 0 to 100, whereby high values reflect a high degree of subjective symptom burden and thus subjective visual impairment. The visual acuity in externally performed eye tests at baseline and follow-ups (FU) was also evaluated. The timepoints for testing were before the start of radiotherapy, at the end of treatment, and 3, 6, 12, and 24 months in FU (times t1-t6). All patients with at least the first annual postradiation FU at the time of the evaluation were included. The correlation between VDS changes and potential influencing factors such as previous therapies, dosimetric data, initial tumor volume, and tumor shrinkage 1 year after treatment was assessed.

RESULTS

A total of 56 patients (45 female/11 male) aged 24-82 years (mean ± SD = 53.9 ± 13.3) treated between March 2017 and September 2019 were included in the analysis. The prescription dose was 54.0 Gy (RBE) with active scanned proton therapy. The mean/D2% dose ± SD for the optic chiasm and ipsilateral optic nerve was 43.4 ± 8.9 Gy (RBE)/49.9 ± 7.1 Gy (RBE) and 35.6 ± 11.7 Gy (RBE)/51.7 ± 4.8 Gy (RBE); the mean/D2% dose ± SD of the contralateral optic nerve was 18.8 ± 12.1 Gy (RBE)/42.4 ± 14.6 Gy (RBE), respectively. A total of 302 data collections were available (t1/t2/t3/t4/t5/t6: n = 56/56/48/56/52/34). Median observation time was 23.6 months. Mean symptom burden decreased over time (mean VDS: t1 29.8 ± 27.9; t2 25.0 ± 27.9; t3 21.8 ± 26.0; t4 22.2 ± 26.0; t5 21.4 ± 26.2; t6 17.3 ± 23.6) with statistically significant improvement at 3‑ and 6‑month FU as well as 1 year after proton therapy (p = 0.0205; p = 0.0187; p = 0.0054). Objective eye tests available in 41/52 patients confirm the trend towards improved visual acuity (97.5% stable/improved until 24-month FU). However, no potential predictor for VDS changes was revealed.

CONCLUSION

Proton treatment of patients with meningioma WHO I with involvement of optical structures does not impair subjective visual performance. After treatment, there is a significant improvement in perceived visual performance.

Neurocognitive considerations in the treatment of meningioma with radiation therapy: applications for quantitative neuroimaging and precision radiation medicine

This article focuses on the role of radiotherapy in the management of meningioma, in the definitive and adjuvant setting and across the spectrum of meningioma grade. Treatment paradigms, informed by clinical evidence, are discussed. Notably, we focus on the impact of radiotherapy on normal brain tissues and neurocognitive function, particularly the dose-dependent changes in white matter and cerebral cortex thickness. Novel imaging techniques have allowed the identification of microstructural changes to eloquent white matter, cortex, and subcortical regions as biomarkers for understanding RT-induced changes in cognitive functioning. Deficits in multiple domains including attention, memory, language and executive function can become more pronounced following radiation. Longitudinal assessment with imaging and neurocognitive testing pre- and post-radiation have allowed correlation between dose to specific regions of the brain and decline in associated domains of neurocognitive function. These findings suggest incorporation of areas at higher risk for neurocognitive sequelae into precision radiation planning. Volumetric arc therapy, advanced planning with cortical sparing, proton therapy and stereotactic radiosurgery are reviewed as options for delivering therapeutic dose to target volumes while minimizing risk to adjacent sensitive regions. The treatment of meningioma is an evolving area, with improving outcomes for higher grade disease in modern trials, where care must be taken to maximize both disease control as well as quality of life for patients.

Health-Related Quality of Life in Intracranial Meningioma: Current Evidence and Future Directions

Historically, largely due to the good prognosis for survival, there has been little attention paid to the possible impact of meningiomas and their treatment on health-related quality of life (HRQoL). However, in the last decade there has been increasing evidence that patients with intracranial meningiomas suffer from long-term decreases in their HRQoL. Compared with controls and normative data, meningioma patients have worse HRQoL scores both before and after intervention and continuing long term (even after >4 years of follow-up). Overall, surgery results in improvements in many aspects of HRQoL. The limited available studies investigating the impact of radiotherapy suggest that this type of treatment decreases HRQoL scores, especially in the long term. There is however only limited evidence on additional determinants of HRQoL. Patients with anatomically complex skull base meningiomas and severe comorbidities, including epilepsy, report the lowest HRQoL scores. Other tumor and sociodemographic characteristics have shown weak associations with HRQoL. Furthermore, about one-third of caregivers of meningioma patients report caregiver burden, warranting interventions to improve caregiver HRQoL. As antitumor interventions may not improve HRQoL scores to be comparable to those of the general population, more attention should be paid to the development of integrative rehabilitation and supportive care programs for meningioma patients.

Quality of life outcomes in incidental and operated meningiomas (QUALMS): a cross-sectional cohort study

INTRODUCTION

Few studies have evaluated meningioma patients' longer-term health-related quality of life (HRQoL) following diagnosis and treatment, particularly in those with incidental, actively monitored tumours.

METHODS

A single-center, cross-sectional study was completed. Adult patients with surgically managed or actively monitored meningioma with more than five years of follow-up were included. The patient-reported outcome measures RAND SF-36, EORTC QLQ-C30 and QLQ-BN20 were used to evaluate HRQoL. HRQoL scores were compared to normative population data. Outcome determinants were evaluated using multivariate linear regression analysis.

RESULTS

243 patient responses were analyzed, and the mean time from diagnosis was 9.8 years (range 5.0-40.3 years). Clinically relevant, statistically significant HRQoL impairments were identified across several SF-36 and QLQ-C30 domains. Increasing education level (β = 2.9, 95% CI 0.9 to 4.9), P = .004), employment (β = 7.7, 95% CI 2.2 to 13.1, P = .006) and absence of postoperative complications (β=-6.7, 95% CI -13.2 to (-)0.3, P = .041) were associated with a better QLQ-C30 summary score. Other tumour and treatment variables were not.

CONCLUSION

This study highlights the longer-term disease burden of patients with meningioma nearly one decade after diagnosis or surgery. Patients with actively monitored meningioma have similar HRQoL to operated meningioma patients. Healthcare professionals should be mindful of HRQoL impairments and direct patients to sources of support as needed.

Idiopathic normal pressure hydrocephalus: postoperative patient perspective and quality of life

BACKGROUND

Idiopathic normal pressure hydrocephalus (iNPH) is a potentially reversible disease. Surgical results have been well described in the literature, but only a few studies investigated the subjective outcome. This study aimed to investigate the patient's expectations about surgery, the perceived improvement after treatment, and its impact on the quality of life (QoL).

METHODS

A new dedicated survey was created to investigate subjectively different aspects of the treatment pathway of iNPH (diagnosis, symptoms, expectations from surgery, surgical operation, surgical results, and postoperative QoL), together with the SF-12 and EQ-5D as validated, standardized tools.

RESULTS

Forty-five patients were included. Forty-three percent of cases received the diagnosis after at least 1 year, with symptoms worsening in 73%, and frustration in 93%. Reaching a diagnosis was important for 100% of patients, with high expectations from surgery; 86% of them hoped to return to a normal life. Seventy-two percent of patients reported a significant postoperative improvement (walking 68%, mood 57%). Memory and incontinence did not improve in 64% of cases. Subjectively, QoL improved in 72% of cases. The SF-12 score is comparable to controls >75 years, but lower than the 65-75 years group. The EQ-5D index was 0.66 (lower than those of the 65-75 years group = 0.823, and >75 years group = 0.724). Pain and discomfort, instead, were lower compared to the healthy population (43% vs 56%). The idea of having an implanted device and of long-term follow-up is not worrying for 80% of patients; approximately two-thirds of them reported a regained control of their lives.

CONCLUSIONS

The importance of early diagnosis and patients' perspective, alongside clinical evaluation, is highlighted. The self-reported evaluations on symptoms and QoL, along with the balance between postoperative worries and benefits, should be discussed preoperatively with patients and relatives, and included postoperatively to comprehensively assess the surgical outcome.

Development and validation of a patient-centered, meningioma-specific quality-of-life questionnaire

OBJECTIVE

Meningiomas can have significant impact on health-related quality of life (HRQOL). Patient-centered, disease-specific instruments for assessing HRQOL in these patients are lacking. To this end, the authors sought to develop and validate a meningioma-specific HRQOL questionnaire through a standardized, patient-centered questionnaire development methodology.

METHODS

The development of the questionnaire involved three main phases: item generation, item reduction, and validation. Item generation consisted of semistructured interviews with patients (n = 30), informal caregivers (n = 12), and healthcare providers (n = 8) to create a preliminary list of items. Item reduction with 60 patients was guided by the clinical impact method, multiple correspondence analysis, and hierarchical cluster analysis. The validation phase involved 162 patients and collected evidence on extreme-groups validity; concurrent validity with the SF-36, FACT-Br, and EQ-5D; and test-retest reliability. The questionnaire takes on average 11 minutes to complete.

RESULTS

The meningioma-specific quality-of-life questionnaire (MQOL) consists of 70 items representing 9 domains. Cronbach's alpha for each domain ranged from 0.61 to 0.91. Concurrent validity testing demonstrated construct validity, while extreme-groups testing (p = 1.45E-11) confirmed the MQOL's ability to distinguish between different groups of patients.

CONCLUSIONS

The MQOL is a validated, reliable, and feasible questionnaire designed specifically for evaluating QOL in meningioma patients. This disease-specific questionnaire will be fundamentally helpful in better understanding and capturing HRQOL in the meningioma patient population and can be used in both clinical and research settings.

The Suprasellar Meningioma Patient-Reported Outcome Survey: a disease-specific patient-reported outcome measure for resection of suprasellar meningioma

OBJECTIVE

Suprasellar meningioma resection via either the transcranial approach (TCA) or the endoscopic endonasal approach (EEA) is an area of controversy and active evaluation. Skull base surgeons increasingly consider patient-reported outcomes (PROs) when choosing an approach. No PRO measure currently exists to assess quality of life for suprasellar meningiomas.

METHODS

Adult patients undergoing suprasellar meningioma resection between 2013 and 2019 via EEA (n = 14) or TCA (n = 14) underwent semistructured interviews. Transcripts were coded using a grounded theory approach to identify themes as the basis for a PRO measure that includes all uniquely reported symptoms. To assess content validity, 32 patients and 15 surgeons used a Likert scale to rate the relevance of items on the resulting questionnaire and the general Patient-Reported Outcomes Measurement Information System-29 (PROMIS29). The mean scores were calculated for all items and compared for TCA versus EEA patient cohorts by using unpaired t-tests. Items on either questionnaire with mean scores ≥ 2.0 from patients were considered meaningful and were aggregated to form the novel Suprasellar Meningioma Patient-Reported Outcome Survey (SMPRO) instrument.

RESULTS

Qualitative analyses resulted in 55 candidate items. Relative to patients who underwent the EEA, those who underwent the TCA reported significantly worse future outlook before surgery (p = 0.01), tiredness from medications 2 weeks after surgery (p = 0.001), and word-finding and memory difficulties 3 months after surgery (p = 0.05 and < 0.001, respectively). The items that patients who received a TCA were most concerned about included medication-induced lethargy after surgery (2.9 ± 1.3), blurry vision before surgery (2.7 ± 1.5), and difficulty reading due to blurry vision before surgery (2.7 ± 2.7). Items that patients who received an EEA were most concerned about included blurry vision before surgery (3.5 ± 1.3), difficulty reading due to blurry vision before surgery (2.4 ± 1.3), and problems with smell postsurgery (2.9 ± 1.3). Although surgeons overall overestimated how concerned patients were about questionnaire items (p < 0.0005), the greatest discrepancies between patient and surgeon relevance scores were for blurry vision pre- and postoperatively (p < 0.001 and < 0.001, respectively) and problems with taste postoperatively (p < 0.001). Seventeen meningioma-specific items were considered meaningful, supplementing 8 significant PROMIS29 items to create the novel 25-item SMPRO.

CONCLUSIONS

The authors developed a disease- and approach-specific measure for suprasellar meningiomas to compare quality of life by operative approach. If demonstrated to be reliable and valid in future studies, this instrument may assist patients and providers in choosing a personalized surgical approach.

Long-term health-related quality of life and neurocognitive functioning after treatment in skull base meningioma patients

OBJECTIVE

Patients with skull base meningioma (SBM) often require complex surgery around critical neurovascular structures, placing them at high risk of poor health-related quality of life (HRQOL) and possibly neurocognitive dysfunction. As the survival of meningioma patients is near normal, long-term neurocognitive and HRQOL outcomes are important to evaluate, including evaluation of the impact of specific tumor location and treatment modalities on these outcomes.

METHODS

In this multicenter cross-sectional study including patients 5 years or more after their last tumor intervention, Short-Form Health Survey (SF-36) and European Organisation for Research and Treatment of Cancer (EORTC) QLQ-BN20 questionnaires were used to assess generic and disease-specific HRQOL. Neurocognitive functioning was assessed with standardized neuropsychological assessment. SBM patient assessments were compared with those of 1) informal caregivers of SBM patients who served as controls and 2) convexity meningioma patients. In addition, the authors compared anterior/middle SBM patients with posterior SBM patients and anterior/middle and posterior SBM patients separately with controls. Multivariable and propensity score regression analyses were performed to correct for possible confounders.

RESULTS

Patients with SBM (n = 89) with a median follow-up of 9 years after the last intervention did not significantly differ from controls (n = 65) or convexity meningioma patients (n = 84) on generic HRQOL assessment. Statistically significantly but not clinically relevantly better disease-specific HRQOL was found for SBM patients compared with convexity meningioma patients. Anterior/middle SBM patients (n = 62) had significantly and clinically relevantly better HRQOL in SF-36 and EORTC QLQ-BN20 scores than posterior SBM patients (n = 27): physical role functioning (corrected difference 17.1, 95% CI 0.2-34.0), motor dysfunction (-10.1, 95% CI -17.5 to -2.7), communication deficit (-14.2, 95% CI -22.7 to -5.6), and weakness in both legs (-10.1, 95% CI -18.8 to -1.5). SBM patients whose primary treatment was radiotherapy had lower HRQOL scores compared with SBM patients who underwent surgery on two domains: bodily pain (-33.0, 95% CI -55.2 to -10.9) and vitality (-18.9. 95% CI -33.7 to -4.1). Tumor location and treatment modality did not result in significant differences in neurocognitive functioning, although 44% of SBM patients had deficits in at least one domain.

CONCLUSIONS

In the long term, SBM patients do not experience significantly more sequelae in HRQOL and neurocognitive functioning than do controls or patients with convexity meningioma. Patients with posterior SBM had poorer HRQOL than anterior/middle SBM patients, and primary treatment with radiotherapy was associated with worse HRQOL. Neurocognitive functioning was not affected by tumor location or treatment modality.

Health-related quality of life in meningioma

Background. Meningiomas are the most common primary intracranial tumor in adults. Although frequently histologically benign, the clinical severity of a lesion may range from being asymptomatic to causing severe impairment of global function and well-being. The diversity of intracranial locations and clinical phenotypes poses a challenge when studying functional impairments, however, more recent attention to patient-reported outcomes and health-related quality of life (HRQOL) have helped to improve our understanding of how meningioma may impact a patient’s life.Methods. Treatment strategies such as observation, surgery, radiation, or a combination thereof have been examined to ascertain their contributions to symptoms, physical and cognitive functioning, disability, and general aspects of daily functioning.Results. This review explores the multidimensional nature of HRQOL and how patients may be influenced by meningiomas and their treatment.Conclusion. Overall, treatment of symptomatic meningiomas is associated with improved HRQOL, cognitive functioning, and seizure control while tumor size, location, histologic grade, and epileptic burden are associated with worse HRQOL.

Functional outcome and quality of life after meningioma surgery: a systematic review

Assessment of long-term functional outcomes after meningioma surgery is important. We systematically reviewed the literature on health-related quality of life (HrQoL) and functional disability (FD) of patients after surgery for intracranial meningiomas. Using PRISMA 2015 guidelines, we screened 289 abstracts and 43 titles were retained for full-paper screening. 15 articles did not present enough data to meet the inclusion criteria and 7 articles failed to assess functional assessment and HrQoL. Twenty-two articles were included in our review. HrQol was assessed in N = 18 publications, most frequently using SF-36 (N = 10), followed by EQ5D-5L (N = 4), EORTC-QLQ (N = 4), and the FACT questionnaire (N = 2). The assessment of FD was reported in N = 11 publications, mostly using the KPS (N = 8). The Barthel index was used in N = 2 publications. Follow-up was reported in N = 12 publications, ranging from 6 months to 9 years. Scientific publications assessing long-term postoperative HrQol and FD in patients undergoing meningioma surgery are scarce and the data are heterogeneously reported, using various scales and follow-up protocols. Efforts should be undertaken to uniformly assess long-term post-operative functional outcomes in meningioma patients.
