Background: No consensus germline testing guidelines currently exist for glioma patients, so the prevalence of germline pathogenic variants remains unknown. This study aims to determine the prevalence and type of pathogenic germline variants in adult glioma.
Methods: A retrospective review at a single institution with paired tumor/normal sequencing from August 2018-April 2022 was performed and corresponding clinical data were collected.
Results: We identified 152 glioma patients of which 15 (9.8%) had pathogenic germline variants. Pathogenic germline variants were seen in 11/84 (13.1%) of Glioblastoma, IDH wild type; 3/42 (7.1%) of Astrocytoma, IDH mutant; and 1/26 (3.8%) of Oligodendroglioma, IDH mutant, and 1p/19q co-deleted patients. Pathogenic variants in BRCA2, MUTYH, and CHEK2 were most common (3/15, 20% each). BRCA1 variants occurred in 2/15 (13%) patients, with variants in NF1, ATM, MSH2, and MSH3 occurring in one patient (7%) each. Prior cancer diagnosis was found in 5/15 patients (33%). Second-hit somatic variants were seen in 3/15 patients (20%) in NF1, MUTYH, and MSH2. Referral to genetics was performed in 6/15 (40%) patients with pathogenic germline variants. 14/15 (93%) of patients discovered their pathogenic variant as a result of their paired glioma sequencing.
Conclusions: These findings suggest a possible overlooked opportunity for determination of hereditary cancer syndromes with impact on surveillance as well as potential broader treatment options. Further studies that can determine the role of variants in gliomagenesis and confirm the occurrence and types of pathogenic germline variants in patients with IDH wild type compared to IDH mutant tumors are necessary.
Background: The objective of this scoping review was to describe the intervention characteristics and effectiveness of psychosocial interventions aimed at managing personality and behavior changes in people with brain tumors. A secondary objective was to explore if these interventions had an impact on outcomes for carers. Personality and behavior changes considered included aggression, apathy, paranoia, disinhibition, and emotional lability.
Methods: This review was conducted following the Joanna Briggs Institute methodology for scoping reviews and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for scoping reviews. Searches were conducted in PsycINFO, CINAHL, Medline (Ovid), and Scopus. We synthesized studies published from 1996 to 2022 that evaluated interventions to manage brain tumor related personality and behavioral changes in adults. A data extraction tool were used based on the Joanna Briggs Institute template. Results are presented in a summary table and a narrative synthesis was conducted.
Results: Three thousand and five hundred and ninety-four records were screened. Title and abstract screening resulted in 29 potentially eligible studies. Full screening excluded 24 articles and 5 interventions met the inclusion criteria. The interventions were diverse in duration, delivery modality, setting, and participation (eg, the patient individually or patient and carer). The interventions reported improvements in the targeted personality and behavior change symptoms for patients with primary brain tumors. Four studies included a measure of personality and behavior change symptoms and two studies included a measure of outcomes for carers and reported improvements in carer knowledge and a reduction in carer distress. All studies sampled fewer than 100 participants. Studies had limited follow-up data and different tools were used to assess the presence and nature of personality and behavior changes.
Conclusions: There is a dearth of psychosocial interventions to support patients and their carers to manage brain tumor related personality and behavior changes.
Routine cognitive assessment for adults with brain cancers is seldom completed but vital for guiding daily living, maintaining quality of life, or supporting patients and families. This study aims to identify cognitive assessments which are pragmatic and acceptable for use in clinical settings. MEDLINE, EMBASE, PsycINFO, CINAHL, and Cochrane were searched to identify studies published in English between 1990 and 2021. Publications were independently screened by two coders and included if they: (1) were peer-reviewed; (2) reported original data relating to adult primary brain tumor or brain metastases; (3) used objective or subjective assessments; (4) reported assessment acceptability or feasibility. The Psychometric And Pragmatic Evidence Rating Scale was used. Consent, assessment commencement and completion, and study completion were extracted along with author-reported acceptability and feasibility data. PROSPERO Registration: CRD42021234794. Across 27 studies, 21 cognitive assessments had been assessed for feasibility and acceptability; 15 were objective assessments. Acceptability data were limited and heterogeneous, particularly consent (not reported in 23 studies), assessment commencement (not reported in 19 studies), and assessment completion (not reported in 21 studies). Reasons for non-completion could be grouped into patient-factors, assessment-factors, clinician-factors, and system-factors. The three cognitive assessments with the most acceptability and feasibility data reported were the MMSE, MoCA, and NIHTB-CB. Further acceptability and feasibility data are needed including consent, commencement and completion rates. Cost, length, time, and assessor burden are needed for the MMSE, MoCA, and NIHTB-CB, along with potentially new computerized assessments suited for busy clinical settings.
Background: Most primary brain tumor patients rely on family caregivers for support. Caregiving can be rewarding, but also leads to significant burden from unmet needs. We aimed to: (1) identify and characterize caregivers' unmet needs; (2) determine associations between unmet needs and wish for support; (3) evaluate acceptability of the Caregiver Needs Screen (CNS) and perceived feasibility in clinical practice.
Methods: Family caregivers of primary brain tumor patients were recruited from outpatient clinics and asked to complete an adapted version of the CNS consisting of 33 common issues caregivers report (item scale 0-10), and the wish for support (yes/no). Participants ranked acceptability and feasibility (item scale 0-7; higher scores being positive) of the adapted CNS. Descriptive and non-parametric correlational analyses were applied.
Results: Caregivers (N = 71) reported 1-33 unmet caregiving needs (M = 17.20, sd = 7.98) but did not always wish for support (range 0-28, M = 5.82, sd = 6.96). A weak correlation was found between total number of unmet needs and wish for support (r = 0.296, P = .014). Most distressing items were patients' changes in memory/concentration (M = 5.75, sd = 3.29), patients' fatigue (M = 5.58, sd = 3.43), and signs of disease progression (M = 5.23, sd = 3.15).Caregivers most often wished support with recognizing disease progression (N = 24), and least often with managing spiritual issues (N = 0). Caregivers evaluated acceptability and feasibility of the CNS tool positively (mean scores ranged 4.2-6.2).
Conclusions: Family caregivers experience distress resulting from many neuro-oncology specific needs, but this is not directly related to wish for support. Family caregiver needs screening could be useful to tailor support to suit their preferences in clinical practice.
Background: The use of so-called "red flags" may be beneficial in identifying patients with metastatic spinal disease. This study examined the utility and efficacy of these red flags in the referral chain of patients surgically treated for spinal metastases.
Methods: The referral chains from the onset of symptoms until surgical treatment for all patients receiving surgery for spinal metastases between March 2009 and December 2020 were reconstructed. The documentation of red flags, as defined by the Dutch National Guideline on Metastatic Spinal Disease, was assessed for each healthcare provider involved.
Results: A total of 389 patients were included in the study. On average, 33.3% of red flags were documented as present, 3.6% were documented as absent, and 63.1% were undocumented. A higher rate of red flags documented as present was associated with a longer time to diagnosis, but a shorter time to definitive treatment by a spine surgeon. Moreover, red flags were documented as present more often in patients who developed neurological symptoms at any point during the referral chain than those who remained neurologically intact.
Conclusions: The association of red flags with developing neurological deficits highlights their significance in clinical assessment. However, the presence of red flags was not found to decrease delays prior to referral to a spine surgeon, indicating that their relevance is currently not sufficiently recognized by healthcare providers. Raising awareness of symptoms indicative of spinal metastases may expedite timely (surgical) treatment and thus improve treatment outcome.
Background: While therapeutically effective, chemoradiotherapy treatment for high-grade glioma (glioblastoma) is often accompanied by side effects. Exercise has been demonstrated to alleviate the adverse effects of such treatments in other cancers. We aimed to evaluate the feasibility and preliminary efficacy of supervised exercise incorporating autoregulation.
Methods: Thirty glioblastoma patients were recruited, five declined exercise and 25 were provided with a multimodal exercise intervention for the duration of their chemoradiotherapy treatment. Patient recruitment, retention, adherence to training sessions and safety were evaluated throughout the study. Physical function, body composition, fatigue, sleep quality, and quality of life were evaluated before and after the exercise intervention.
Results: Eight of the 25 participants commencing exercise withdrew prior to completion of the study (32%). Seventeen patients (68%) demonstrated low to high adherence (33%-100%) and exercise dosage compliance (24%-83%). There were no reported adverse events. Significant improvements were observed for all trained exercises and lower limb muscle strength and function with no significant changes observed for any other physical function, body composition, fatigue, sleep, or quality of life outcomes.
Conclusions: Only half of glioblastoma patients recruited were willing or able to commence, complete or meet minimum dose compliance for the exercise intervention during chemoradiotherapy indicating the intervention evaluated may not be feasible for part of this patient cohort. For those who were able to complete the exercise program, supervised, autoregulated, multimodal exercise was safe and significantly improved strength and function and may have prevented deterioration in body composition and quality of life.
