Validation of the M.D. Anderson Symptom Inventory Brain Tumor Module (MDASI-BT)

Clinical Outcome Assessment Tools for Evaluating the Management of Gliomas

In recent times, a greater emphasis has been placed on framing patient clinical assessments and QOL as both endpoints and prognostic factors for neuro-oncological care. However, there is currently a lack of consensus on the most effective metrics and instruments for use in patients with primary brain tumors. Due to the heterogeneity in clinical characteristics, histological classification, anatomical location, and available treatment modalities for glioma, quantifying patient clinical condition and QOL within this unique population is particularly challenging. In this paper, we comprehensively review the available literature on the use of clinical assessment tools in glioma patients, highlighting the strengths and limitations of prominent instruments. We demonstrate that clinical outcome assessment (COA) instruments provide valuable and complementary insights into the physical, psychological, and spiritual well-being of glioma patients.

A Mannosylated peptidyl lipid CManDA doped into cytidinyl/cationic lipids efficiently delivers siG12Ss to lung cancer in vivo

Gene therapy has attracted widespread attention in recent years, and one of the important delivery systems is the LNP. However, many LNPs have potential toxicity and accumulate in the liver. Here, we designed and synthesized a Gemini-type mannosylated peptidyl lipid called CManDA(M), which, in combination with the cytidinyl lipid DNCA(D) and the peptidyl lipid CLD(C) (D/50C/50M), could transfect siRNA (siG12S) into A549 cells to target and silence the KRASG12S gene. The fluorescence intensity in the tumor area of the D/50C/50M/Cy5.5-siG12S group increased by approximately 2.5 times. Furthermore, full 2'-F/2'-OMe-modified siG12Ss could also be transfected by D/50C/50M into cells, resulting in target gene silencing. The tumor weight in the D/50C/50M/M3 group (1.5 mg/kg, i.v.) was reduced by 50 % after administration in a mouse axillary tumor (A549) model, whereas the tumor bioluminescence intensity was only approximately 30 % of that in the blank group in a mouse orthotopic lung cancer model and showed no significant toxicity. Further studies revealed that the mannose groups of CManDA can be exposed on the nanoparticle surface to bind lectins, and CManDA can also shield the formation of a protein corona and alter the composition of the protein corona, which aids in the enhancement of its active targeting function. CManDA is expected to be a safe and effective helper lipid for tumor-targeted delivery of siRNA in vivo.

Prevalence, risk factors, and impacts of sleep disturbances in patients with primary brain tumors: a systematic review

Sleep disturbances are common in patients with primary brain tumors (PBT), significantly affecting their health-related quality of life (QoL), emotional well-being, cognitive function, and clinical outcomes. These disturbances not only impact the patients themselves but also place a burden on their families and caregivers. Despite growing recognition of these problems, a comprehensive understanding of their prevalence, severity, and risk factors remains limited. This systematic review aimed to update the evidence on sleep disturbances in PBT patients, focusing on prevalence, risk factors, and management strategies. Following PRISMA 2020 guidelines, we searched PubMed, EMBASE, Scopus, PsycINFO, and CINAHL for studies published from September 2015 to June 2024. Eligible studies assessed sleep disturbances in adult PBT patients using validated methods. Studies with mixed-cancer samples, pediatric patients, or lacking validated sleep assessments were excluded. A total of 11 studies were included, revealing high rates of sleep disturbances, ranging from 9.2% to over 60%, varying by tumor type and treatment stage. Key risk factors included older age, female gender, certain tumor types (e.g., pituitary), perioperative sleep quality, and psychological distress. Sleep disturbances were linked to worse clinical outcomes, including higher mortality and burden. Addressing sleep disturbances through routine assessment and targeted interventions is essential for improving outcomes in this population.

Patient-Reported Outcomes in Radiation Oncology

Patient-reported outcomes (PROs) assessments arguably provide the most accurate description of the patient experience, as they are directly derived from the patient without the filter of a provider. Utilizing instruments to assess PROs in radiation oncology enables a provider to measure pretreatment, on-treatment, and posttreatment symptoms. In the clinic, PROs are supplemental to physician-derived ratings that help create a complete clinical picture of a patient at a given time point to inform shared decision-making. A compilation of PROs that arise within trials, specific for given treatment regimes, will be invaluable for patients faced with choosing between options.

Cognitive Decline in Glioblastoma (GB) Patients with Different Treatment Modalities and Insights on Untreated Cases

BACKGROUND

Cognitive decline is common in patients with Glioblastoma (GB), occurring in both treated and untreated cases. It frequently presents as impairments in memory, attention, language, or other cognitive functions. In addition, these cognitive deficits can affect quality of life, functional independence, and overall survival, and they are associated with psychiatric conditions such as anxiety and depression.

METHODS

This narrative review evaluates cognitive deficits in GB patients, both with and without treatment. It also explores the impact of tumor features such as size, location, and histology, along with patient characteristics such as age and education, and discusses the effects of standard therapies, such as surgery, chemotherapy, and radiotherapy, on cognitive outcomes.

RESULTS

Cognitive impairment in GB is influenced by tumor- and patient-specific factors, as well as treatment modalities. Initially, combination therapies such as surgery, radiotherapy, and chemotherapy may improve cognitive domains by reducing tumor burden, relieving cerebral edema, and reducing mass effects, subsequently bringing indirect effects of improved mental health and mood. While certain treatments like radiotherapy and chemotherapy carry risks of delayed neurotoxicity, studies indicate that, on balance, treated patients generally show better preservation or improvement in cognitive function than those who go untreated. However, excessive treatment aggressiveness and cumulative neurotoxic effects may diminish cognitive benefits.

CONCLUSION

Cognitive function is an independent factor in GB, which could affect survival in GB patients, therefore making routine cognitive assessments essential for prognosis, treatment planning, and rehabilitation. Neuroprotective agents, cognitive rehabilitation, and personalized, multidisciplinary strategies can help optimize both survival and cognitive preservation.

The COVID-19 pandemic experience for patients with central nervous system tumors: Differences in patient-reported outcomes and practice recommendations

Background

This study explored differences in patient-reported outcomes (PROs) for patients with central nervous system (CNS) tumors during COVID, compared to pre-pandemic assessments, in light of impacted access to in-person care.

Methods

Patient-reported outcomes (PROMIS-Anxiety and Depression Short-Forms, EQ-5D-3L, MDASI-BT/Spine, NeuroQoL-Perceived Cognitive Functioning) were collected from 149 participants on the Neuro-Oncology Branch Natural History Study seen during the first year of COVID between March 2020 and February 2021, which were compared to assessments collected pre-COVID. Paired sample t-tests and proportion tests (z-tests) were used to compare PROs with effect sizes reported using Hedges g and Cohen's h. Logistic regression models with backwards selection were used to identify risk factors for high levels of depression and anxiety pre- and during COVID.

Results

Participants were primarily male (54%) and Caucasian (84%) with a median age of 46 (range 20-79) and 66% had high-grade tumors. More patients reported moderate-severe depressive symptoms during the COVID year, compared to pre-COVID assessments (13% vs 8%, Cohen's h = 0.17, P = .021), with modest increases in symptom burden and cognitive dysfunction reported as well. Logistic regressions revealed that during COVID, concurrent moderate-severe distress and low tumor grade predicted depression and anxiety, with psychotropic medication use also predicting depression while active treatment predicted anxiety.

Conclusion

During COVID, patients experienced higher levels of depression, which has the potential to negatively influence treatment success and survival. Future work is needed to incorporate innovative tools and interventions that can be utilized remotely to identify and target mood disturbance in these vulnerable patients.

Sleep disorders associated with cranial radiation-A systematic review

BACKGROUND

Radiation is the standard-of-care treatment for primary brain tumors (PBTs) but may have profound effects on sleep that have not yet been fully characterized. This systematic review aims to further our understanding of radiation therapy on the risk of development of sleep disorders in patients with PBTs, as well as potential opportunities for prevention and treatment.

METHODS

A systematic search of PubMed, Embase, and Web of Science was performed (last Jan 2024) with predefined inclusion (PBT patients, radiation therapy, somnolence/circadian disruption) and exclusion (reviews/abstracts/cases/chapters, non-PBT cancer, lack of radiation) criteria, yielding 267 papers initially and 38 studies included. Data extraction and analysis (descriptive statistics, individual study summary) focused on the incidence of sleep disturbances, radiation types/doses, and pharmacologic interventions. Risk of bias assessment was conducted with the Effective Public Health Practice Project's Quality Assessment Tool for Quantitative Studies.

RESULTS

The included 38 studies (n = 2948 patients) demonstrated a high incidence of sleep disturbances in patients with PBTs throughout radiation therapy, but primarily from the end of radiation to 6 months after. Sleep symptoms were associated with radiation (dose-dependent), and pharmacotherapies were helpful in patients with formal sleep disorder diagnoses. Terminology and incidence reporting of sleep symptoms are inconsistent, and many studies had a high risk of bias.

CONCLUSIONS

This systematic review highlights the ongoing challenges with sleep symptoms/disorders related to cranial irradiation treatment in the primary brain tumor population. Further investigations on the interconnectedness of sleep disturbance constructs and possible pharmacotherapies to alleviate symptoms are warranted.

Prospective assessment of end-of-life symptoms and quality of life in patients with high-grade glioma

Background

Glioblastoma and high-grade glioma (HGG) remain non-curable diseases. Symptoms and Quality-of-life (QoL) in the end-of-life (EoL) phase have not been prospectively studied with validated instruments. Therefore, we prospectively assessed symptom progression, symptom management, and hospice utilization in patients with treatment-refractory progressive HGG.

Methods

Patients failing bevacizumab and presenting with a Karnofsky performance score of ≤60, and their caregivers, were eligible. Symptoms, medication, and clinical management were tracked with serial telephone calls every 2 weeks until death utilizing clinical evaluations and the MD Anderson Symptom Inventory Brain Tumor Module (MDASI-BT). The MDASI-BT rates symptoms on a scale from 0 (no symptoms) to 10 (worst).

Results

Fifty-four patient-caregiver dyads were enrolled in the study. Amongst 50 evaluable patients, the most severe symptoms during the last 2 weeks prior to death were drowsiness (9.09 ± 1.44), difficulty with concentration (8.87 ± 2.29), fatigue (8.63 ± 2.03), difficulty speaking (8.44 ± 2.42), weakness (8.27 ± 3.44), and difficulty with understanding (7.71 ± 2.94). All symptoms, except weakness and memory impairment, which were high at baseline, showed statistically significant progression. Seizures were rare and did not progressively worsen near the end of life (1.38 ± 3.02). The decision-making composite score almost doubled during the EoL phase (8.58 ± 1.53).

Conclusions

This is the first prospective study describing symptoms and QoL issues in patients with HGG. Patients suffer from high morbidity in the EoL phase and should be offered early palliative and hospice care to assure proper symptom management and advance care planning.

Sexual dysfunction after surgery for primary sporadic cranial meningiomas: prevalence and risk factors

BACKGROUND

Although postoperative quality of life (QoL) has been studied in relation to a variety of aspects following meningioma resection, the impact of meningiomas on sexual life has not been investigated. The aim of this study is to determine the impact of cranial meningioma surgery on patients' postoperative sexual life.

METHODS

A standardized questionnaire, anonymous and based on the Arizona Sexual Experiences Scale (ASEX), was sent to 87 patients who had been selected for participation in the study based on the following criteria: a postoperative Karnofsky performance of ≥ 80 and below 60 years of age at diagnosis.

RESULTS

53 patients (53/87; 61%) responded to the survey. The study identified eleven patients (20.8%) who reported sexual dysfunction (SD) according to ASEX criteria. Six of these patients were women (55%) and five were men (45%). Univariable analysis revealed that SD was observed with greater frequency in patients with non-skull base tumors (p = 0.006) and in those with a left-hemispheric meningioma (p = 0.046). Multivariable analysis revealed that non-skull base tumor location is the only independent factor being associated with SD (OR = 5.71, 95% CI = 1.02-31.81, p = 0.047).

CONCLUSION

This first investigation of sexual functioning post-surgery for cranial meningiomas indicates that SD is a prevalent issue among non-skull base meningioma patients. Consequently, we recommend that pre- and postoperative sexual health should be further addressed in future QoL investigations of cranial meningioma patients.

Environmental Enrichment and Health Outcomes Among Low-Grade Glioma Brain Tumor Survivors

ABSTRACT

BACKGROUND: Brain tumor survivors who received radiotherapy (RT) are at a disproportionately increased risk of accelerated aging and symptom burden. We aim to examine the association between environmental enrichment (EE) and health outcomes among low-grade glioma survivors who received brain RT. METHODS: The study used a cross-sectional cohort design, enrolling participants approximately 5 years from diagnosis. The construct of EE consisted of social network, physical activity, employment status, and financial stability. Berkman-Syme Social Network Index, International Physical Activity Questionnaire, Vocational Index Scale, and a Socioeconomic Questionnaire were used to measure the construct of EE. Health outcome measures included the Montreal Cognitive Assessment, Symbol Digit Modality Test, clinical brain magnetic resonance images (pre-RT, approximately 2-3 years after RT, and approximately 5 years after RT), Karnofsky Performance Status Scale, and the MD Anderson Symptom Inventory Brain Tumor Module. Ordinal logistic regression estimated the association between levels of EE and health outcomes. RESULTS: Thirty-nine participants completed the study and experienced varying levels of EE. The median age was 44 years old, ranging from 26 to 78 years old. Nineteen individuals were diagnosed with oligodendroglioma, and 18 were diagnosed with astrocytoma. Thirteen participants had low EE, 17 had moderate EE, and 9 had high EE. Although not statistically significant, we observed patterns of increasing health outcomes (Montreal Cognitive Assessment, Symbol Digit Modality Test, and Karnofsky Performance Status Scale) related to increasing levels of EE. CONCLUSION: This study is an initial exploration into the role of EE in health outcomes and survivorship programs for persons with glioma. Future research should assess EE before treatment or at the time of diagnosis and be longitudinal to accurately ascertain the association between EE and health outcomes. Comprehensive neuro-oncology survivorship programs structured to facilitate EE may reduce symptom burden, promote neuroplasticity, and improve cognitive and functional outcomes after brain radiation.

Current status and influencing factors of fear disease progression in Chinese primary brain tumor patients: A mixed methods study

OBJECTIVE

In this study, we investigated the fear of disease progression in Chinese PBT patients and examined the correlation between sociodemographic, clinical, and psychological variables of patients with the fear of progression (FoP). Additionally, the study also evaluated the subjective experience of FoP in patients with primary brain tumors (PBT).

METHODS

A mixed-methods study was conducted between March 2022 and December 2023, consisting of two phases: a quantitative approach in phase I, and a qualitative approach in phase II. In phase I, 305 patients with PBT filled in several questionnaires. An analysis was performed to identify potential predictors associated with FoP. In phase II, semi-structured interviews were conducted with 16 participants whose FoP scores were ≥ 34 in phase I to obtain information on their personal experiences with FoP.

RESULTS

The results of the quantitative study showed that 192 (63 %) patients experienced high levels of FoP. The mean score of fear of progression was (34.02±6.78). Young age, high disease uncertainty, low social support, high negative coping and low positive coping are important factors affecting FoP in PBT patients. Qualitative research focused on three themes: triggers, coping styles, and the help needed.

CONCLUSION

Enhanced screening and assessment of FoP is essential to identify dysfunctionin PBT. Meanwhile, the implications of these predictors for enhanced healthcare professional education and patient self-management may help healthcare providers implement relevant interventions promptly and help patients reduce their FoP. However, due to limitations such as sample, reporting bias, and specific mechanisms between predictors and FOPs that have not yet been explored in depth, further exploration is needed in the future.

A Phase II Study of Atezolizumab, Pertuzumab, and High-Dose Trastuzumab for Central Nervous System Metastases in Patients with HER2-Positive Breast Cancer

PURPOSE

Patients with HER2-positive breast cancer brain metastases have few effective systemic therapy options. In a prior study, pertuzumab with high-dose trastuzumab demonstrated a high clinical benefit rate (CBR) in the central nervous system (CNS) in patients with brain metastases. The current trial evaluated whether the addition of atezolizumab to this regimen would produce further improvements in CNS response.

PATIENTS AND METHODS

This was a single-arm, multicenter, phase II trial of atezolizumab, pertuzumab, and high-dose trastuzumab for patients with HER2-positive breast cancer brain metastases. Participants received atezolizumab 1,200 mg i.v. every 3 weeks, pertuzumab (loading dosage 840 mg i.v., then 420 mg i.v. every 3 weeks), and high-dose trastuzumab (6 mg/kg i.v. weekly for 24 weeks, then 6 mg/kg i.v. every 3 weeks). The primary endpoint was CNS overall response rate per Response Assessment in Neuro-Oncology Brain Metastases criteria. Key secondary endpoints included CBR, overall survival, and safety and tolerability of the combination.

RESULTS

Among 19 enrolled participants, two had a confirmed intracranial partial response for a CNS overall response rate of 10.5% (90% confidence interval, 1.9%-29.6%). The study did not meet the prespecified efficacy threshold and was terminated early. The CBR was 42.1% at 18 weeks and 31.6% at 24 weeks. Seven patients (36.8%) required a dose delay or hold, and the most frequent any-grade adverse events were diarrhea (26.3%) and fatigue (26.3%).

CONCLUSIONS

The addition of atezolizumab to pertuzumab plus high-dose trastuzumab does not result in improved CNS responses in patients with HER2-positive breast cancer brain metastases.

Differences in Symptom Burden in Primary Brain Tumor Patients Based on Sex, Race, and Ethnicity: a Single-Center Retrospective Study

BACKGROUND

Symptom burden affects quality of life and prognosis in primary brain tumor (PBT) patients. Knowing whether symptom burden varies based on sex, race, or ethnicity may affect the interpretation of the relationship between symptoms and survival may reveal issues with applying the tools to measure symptom burden to different groups and may identify inequities in symptom management that need to be addressed at a system level. To determine whether symptoms in PBT patients vary across demographic groups, we conducted a retrospective chart review of symptom burden collected as part of routine care in a diverse population.

METHODS

Patient demographics and scores on the MD Anderson Symptom Inventory-Brain Tumor (MDASI-BT) module were extracted from the electronic medical record for patients seen in the Inova Neuro-oncology Clinic between March 2021 and June 2022. MDASI-BT scores were compared based on side of tumor, sex, race, and ethnicity for the entire population and for the subset with gliomas.

RESULTS

We included 125 people, of whom 85 had gliomas. For both the entire group and the subgroup with gliomas, about 40% were female and about 40% were non-White race. No differences in symptom burden were seen between males and females. Pain and numbness/tingling symptom burden were higher in both the entire population and the glioma subgroup for people of Hispanic/Latino/Spanish ethnicity and for people of races other than White or Middle Eastern self-identification.

CONCLUSIONS

Pain, weakness, and numbness/tingling varied significantly across racial and ethnic groups. Further research is needed to validate this finding in other populations and determine its cause.

Identifying associations between sample characteristics, symptoms, and self-efficacy differences in adult patients with rare tumors of the central nervous system who participated in a novel web-based natural history study

OBJECTIVE

High self-efficacy is associated with improved self-care and reduced symptoms in cancer patients but has not been fully interrogated in adults with central nervous system (CNS) cancers. We aimed to identify the relationship between self-efficacy levels in managing emotions (SEMEM) and social interactions (SEMSI) by examining sample characteristics and symptom burden.

METHODS

Sample characteristics and patient-reported outcome (PRO) measures addressing self-efficacy (PROMIS SEMEM & SEMSI) and symptom burden (MDASI BT or SP) were collected in a novel web-based study of 158 adult patients diagnosed with rare CNS tumors.

RESULTS

The sample was predominantly female (73%), diagnosed with an ependymoma (66%), and had a median age of 45 (19-75). Low SEMEM was associated with a longer duration of symptoms before surgery (r = -0.26) and female gender (92%) among brain tumor (BT) participants and in spinal cord tumors (SCT), those with lower education (r = 0.29). Reporting low SEMSI was associated with being married (42%), lower education (r = 0.22), and a prolonged time with symptoms before surgery (r = 0.29) in those with BTs, with no associations identified in SCT. More severe mood-related interference (including mood, enjoyment of life, and relationship with others) was associated with lower SEMEM among both locations (r = -0.61 brain, r = -0.28 spine) and SEMSI in BT participants (r = -0.54).

CONCLUSIONS

Low self-efficacy was linked to a prolonged time between symptom onset and initial surgery, education, gender, and marital status and was associated with higher mood-related interference. Understanding characteristics associated with low self-efficacy underscores a need for future studies to tailor interventions that enhance self-efficacy.

Simulation-based caregiving skills training for family members of high-grade glioma patients

Background

Because family caregivers of patients with a high-grade glioma experience high levels of distress and feel unprepared to perform the complex caregiving tasks associated with the disease and its treatment, we pilot-tested a caregiving skills intervention that integrates hands-on caregiving with coping skill training.

Methods

In this single-arm trial, caregivers participated in a 4-session research nurse-led intervention involving simulation-based caregiving skills training at the hospital and psychoeducation delivered via videoconference. We collected measures of patients' and caregivers' psychological symptoms; caregivers' caregiving self-efficacy and role adjustment; and patients' cancer-related symptoms (MDASI) at baseline and again postintervention. We tracked feasibility data.

Results

We approached 29 dyads of which 10 dyads (34%) consented. All patients (mean age: 60 years, 89% male) and caregivers (mean age: 58 years, 80% female, 80% spouses) completed the baseline and 7 dyads completed the follow-up assessments (attrition was related to patient's hospice transfer). Seven caregivers completed all 4 sessions and rated the program as beneficial. Paired t-tests revealed a significant improvement in caregiving self-efficacy at 6 weeks postintervention (t = -3.06, P = .02). Although improvements in caregiver role adjustment and patient and caregiver symptoms were not observed, no decreases in symptom burden or role adjustment were found during the follow-up period.

Conclusions

This novel supportive care program appears to be safe, feasible, acceptable, and perceived as useful for caregivers of patients with high-grade glioma. Based on feasibility indicators and a signal of intervention efficacy, a randomized controlled trial is warranted.

Self and proxy symptom reporting in glioma patient-caregiver dyads: the role of psychosocial function in rating accuracy

BACKGROUND

Illness-related communication and depressive symptoms within families may play an important role in caregivers' ability to accurately understand patients' symptom burden. We examined the associations between these psychosocial factors and symptom accuracy in patients with glioma and their family caregivers.

METHODS

Patients and caregivers (n = 67 dyads) completed measures of depressive symptoms (CES-D), illness communication (CICS), and QOL (SF-36). Patients reported on their own cancer-related symptoms (MDASI-BT) while caregivers reported on their perception of the patients' symptoms (i.e., proxy reporting). Paired t-tests and difference scores were used to test for agreement (absolute value of difference scores between patients and caregiver proxy symptom and interference severity reports) and accuracy (caregiver underestimation, overestimation, or accurate estimation of patient symptom and interference severity).

RESULTS

Clinically significant disagreement was found for all means scores of the MDASI-BT subscales except for gastrointestinal symptoms and general symptoms. Among caregivers, 22% overestimated overall symptom severity and 32% overestimated overall symptom interference. In addition, 13% of caregivers underestimated overall symptom severity and 21% of caregivers underestimated overall symptom interference. Patient illness communication was associated with agreement of overall symptom severity (r=-0.27, p = 0.03) and affective symptom subscale (r=-0.34, p < 0.01). Caregivers' reporting of illness communication (r=-0.33, p < 0.01) and depressive symptoms (r = 0.46, p < 0.0001) were associated with agreement of symptom interference. Caregiver underestimating symptom severity was associated with lower patient physical QOL (p < 0.01); caregiver underestimating symptom interference was associated with lower patient physical QOL (p < 0.0001) and overestimating symptom interference was associated with lower patient physical QOL (p < 0.05). Patient and caregiver mental QOL was associated with caregiver underestimating (p < 0.05) and overestimating (p < 0.05) symptom severity.

CONCLUSION

The psychosocial context of the family plays an important role in the accuracy of symptom understanding. Inaccurately understanding patients experience is related to poor QOL for both patients and caregivers, pointing to important targets for symptom management interventions that involve family caregivers.

Evaluating the sensitivity of EQ-5D-5L in patients with brain metastases: a secondary analysis of NRG CC001

BACKGROUND

EuroQoL EQ-5D-5L is a commonly used measure of health-related quality of life in clinical trials given the use of its index score as a measure of health utilities. It is unclear whether EQ-5D-5L is sensitive to changes in neurocognitive function and progression that occur following brain radiation. This study sought to evaluate the sensitivity of EQ-5D-5L in reflecting these changes.

METHODS

A secondary analysis of NRG Oncology CC001 was performed. Mean EQ-5D-5L index and visual analog scale (VAS) score changes from baseline between groups of patients stratified by neurocognitive function and intracranial progression status were assessed. MD Anderson Symptom Inventory for brain tumor (MDASI-BT) symptom and interference items were also analyzed between groups.

RESULTS

EQ-5D-5L mean index and VAS score changes between patients who had cognitive failure and those who had preserved cognition showed no statistically significant differences at any timepoint. In contrast, VAS changes at 4 months (1.61 vs -5.13, P = .05) and 6 months (8.17 vs -0.14, P = .04) were significantly improved in the patients who survived without intracranial progression. MDASI-BT cognitive factor scores were improved in the cohort of patients with preserved neurocognitive function at 2 months (1.68 vs 2.08, P = .05) and 4 months (1.35 vs 1.83, P = .04). MDASI-BT symptom interference was significantly associated with intracranial progression at 4 months, but not with neurocognitive status.

CONCLUSION

EQ-5D-5L index and VAS scores were not sensitive to neurocognitive changes that patients experienced, but VAS scores were sensitive to progression. This study challenges the routine use of EQ-5D as a quality of life metric in brain metastases clinical trials that are focused on preventing neurocognitive dysfunction.

The relationship between social determinants of health and neurocognitive and mood-related symptoms in the primary brain tumor population: A systematic review

Social determinants of health (SDOH) impact cancer-related health outcomes, including survival, but their impact on symptoms is less understood among the primary brain tumor (PBT) population. We conducted a systematic review to examine the relationships between SDOH and neurocognitive and mood-related symptoms among the PBT population. PubMed, EMBASE, and CINAHL were searched using PROGRESS criteria (place of residence, race/ethnicity, occupation, gender/sex, religion, education, socioeconomic status, and social capital) on March 8th, 2022. Two individuals screened and assessed study quality using the NHLBI Assessment Tool for Observational Cohort and Cross-sectional Studies. Of 3006 abstracts identified, 150 full-text articles were assessed, and 48 were included for a total sample of 28 454 study participants. Twenty-two studies examined 1 SDOH; none examined all 8. Four studies measured place of residence, 2 race/ethnicity, 13 occupation, 42 gender, 1 religion, 18 education, 4 socioeconomic status, and 15 social capital. Fifteen studies assessed neurocognitive and 37 mood-related symptoms. While higher education was associated with less neurocognitive symptoms, and among individuals with meningioma sustained unemployment after surgery was associated with depressive symptoms, results were otherwise disparate among SDOH and symptoms. Most studies were descriptive or exploratory, lacking comprehensive inclusion of SDOH. Standardizing SDOH collection, reducing bias, and recruiting diverse samples are recommended in future interventions.

Evaluating the heterogeneity of hippocampal avoidant whole brain radiotherapy treatment effect: A secondary analysis of NRG CC001

BACKGROUND

Hippocampal avoidant whole brain radiotherapy (HA-WBRT) is the standard of care for patients needing WBRT for brain metastases. This study, using existing data from NRG Oncology CC001 including baseline tumor characteristics and patient-reported MD Anderson Symptom Inventory-Brain Tumor (MDASI-BT) scores, sought to identify subgroups of patients that demonstrate differential neuroprotective treatment response to HA-WBRT.

METHODS

An exploratory analysis of NRG CC001, a phase 3 trial in which 518 patients were randomly assigned to WBRT plus memantine or HA-WBRT plus memantine, was performed. Rates of neurocognitive function failure (NCFF) were estimated between subgroups and stratified by arm. Covariate and subgroup interaction with differential treatment response were calculated.

RESULTS

The benefit of HA-WBRT on decreasing NCFF was seen in patients living ≥ 4 months (HR 0.75, 95% CI: 0.58-0.97, P = .03), whereas patients living < 4 months derived no significant neurocognitive benefit. A significant association between baseline MDASI-BT cognitive factor and treatment response (interaction P = .03) was identified. Patients with lower MDASI-BT scores (less patient-reported cognitive impairment) derived significantly greater benefit (HR = 0.64, 95% CI: 0.48-0.85, P = .002) compared to those with highest MDASI-BT scores (HR = 1.24, 95% CI: 0.76-2.04, P = .39). Tumor histology also had a significant interaction (P = .01) with treatment response. Primary lung histology patients derived cognitive failure risk reduction (HR = 0.58, 95% CI: 0.43-0.77, P = .0007) from HA-WBRT, in contrast to nonlung primary histology patients (HR = 1.15, 95% CI: 0.78-1.50, P = .48).

CONCLUSIONS

Differential neuroprotective response to HA-WBRT was identified in this analysis. Patients surviving ≥ 4 months derived benefit from HA-WBRT. There is evidence of heterogeneity of treatment effect for patients with less severe patient-reported cognitive impairment at baseline and those with primary lung histology.

A Shifting Paradigm Toward Family-Centered Care in Neuro-Oncology: A Longitudinal Quasi-Experimental Mixed-Methods Feasibility Study

Family-centered intervention can help families facing illness-related issues. We investigated the feasibility of Family and Network Conversations (FNCs) in high-grade glioma patients and their families. Quasi-experimental feasibility study with longitudinal mixed-methods design. Patients and families were invited to three FNCs over 1 year. They completed questionnaires at four time points and expressed their perspectives on the intervention through telephone interviews. Nurses' perspectives were collected in a focus group. Twenty-one patients and 47 family members were included. On average, patients were 66 years old, mainly male, married, living with caregivers, with unifocal cancer. On average, caregivers were 47 years old, mainly female, being spouses or children of the patient. Quantitative and qualitative data did not always match and expanded each other. Nurse-delivered FNCs holistically addressed families' needs while strengthening family's dialogue and union. Nurses felt empowered, underling that advanced competencies were required. Nurse-delivered FNCs are feasible to provide family-centered care, but they should be tailored to each family's needs.

Effects of dependent care theory-based post-surgical home care intervention on self-care, symptoms, and caregiver burden in patients with primary brain tumor and their caregivers: a randomized controlled trial

PURPOSE

This study aimed to examine the effect of dependent care theory-based post-surgical home care intervention on self-care, symptoms, and caregiver burden in primary brain tumor patients and their caregivers.

METHODS

A parallel-group randomized controlled trial was conducted with patients who underwent surgery for a primary brain tumor between March 2019 and January 2020 in a tertiary hospital and with caregivers who cared for them at home. Eligible patients and caregivers were determined by block randomization. Outcome measures included validated measures of self-care agency (Self-Care Agency Scale), symptoms and interference by symptoms (MD Anderson Symptom Inventory Brain Tumor-Turkish Form), and caregiver burden (Caregiver Burden Scale). Two-way analysis of variance was used in repeated measurements from general linear models compared to scale scores.

RESULTS

Self-care agency was significantly higher in the intervention group than in the control group in the first and sixth months after surgery (p < 0.05). The severity of the patients' emotional, focal neurologic, and cognitive symptoms and interference by symptoms were significantly lower in the intervention group than in the control group (p < 0.05). Caregiver burden was significantly lower in the intervention group in the first, third, and sixth months after surgery (p < 0.05).

CONCLUSION

Dependent care theory-based post-surgical home care intervention increased patients' self-care and reduced symptoms and their effects. It also reduced the caregiver burden. Dependent care theory can guide the nursing practices of nurses who provide institutional and/or home care services to patients with chronic diseases and their caregivers.

Measurement Properties of Patient-Reported Outcome Measures for Adolescent and Young Adult Survivors of a Central Nervous System Tumor: A Systematic Review

Purpose: To identify and evaluate patient-reported outcome measures (PROMs) for assessing survivorship-related concepts for adolescent and young adult (AYA) survivors of central nervous system (CNS) tumors. Methods: We searched five electronic databases. Two researchers independently screened all titles for inclusion and used consensus-based standards for the selection of health measurement instruments (COSMIN) guidance to grade the quality of evidence for each measurement property. Results: Four studies met eligibility criteria: single-item pain thermometer; single-item fatigue thermometer; 37-item pediatric functional assessment of cancer therapy-brain tumor survivors, measuring quality of life; and 12-item Perceived Barriers Scale to assess barriers to employment. The Perceived Barrier Scale showed high-quality evidence for internal consistency and moderate quality evidence for construct and structural validity. Evidence for the measurement properties of the other PROMs was low-to-moderate quality. Conclusion: We found one PROM with sufficient evidence for good measurement properties to support its use. This warrants development and evaluation of further PROMs to inform ongoing supportive care for this population. Implications for Cancer Survivors: The Perceived Barriers Scale is sufficiently validated and could be considered to guide support for AYA survivors of CNS tumors to achieve their employment goals.

Resilience of Patients With Brain Tumor While Awaiting Surgery

ABSTRACT

BACKGROUND: Resilience is the ability of patients to adapt effectively when given a diagnosis of an illness. While awaiting brain tumor surgery, patients often experience uncertainty from brain tumor-related symptoms resulting in inducing depressive symptoms, having physical disability, and reducing quality of life. Resilience studies have been widely conducted in the postoperative phase with a limited knowledge on the preoperative phase. This study aimed to identify predictors of resilience while awaiting brain tumor surgery. METHODS: This cross-sectional predictive study includes 100 participants 18 years and older, with diagnosis of brain tumors, and waiting for brain tumor surgery at the outpatient department of 1 tertiary hospital in Bangkok between August 2022 and February 2023. Multiple linear regression was used to examine the predictors of resilience. RESULTS: Most of the sample (77%) were female with a mean age of 52.71 (13.17) years. The most common type of brain tumor was meningioma (38%). The median waiting time since brain tumor diagnosis until the date of preadmission for operation was 18 (3-1464) days. Symptom severity, social support, and treatment plan were able to explain 37.3% of the variance of resilience in patients awaiting brain tumor surgery ( F = 19.077, P < .01, R2 = 0.373, adjusted R2 = 0.354). CONCLUSION: Resilience is an important skill for patients with brain tumor to manage uncertainty events that occur in their lives. The preoperation phase needs to assess both physical and mental tumor-related symptoms, and include caregivers as part of the care, to promote resilience skill for patients awaiting brain tumor surgery.

Characterization of patients with brain metastases referred to palliative care

PURPOSE

In this study, we aimed to assess the clinical characteristics, reasons for referral, and outcomes of patients with brain metastases (BM) referred to the supportive care center.

METHODS

Equal numbers of patients with melanoma, breast cancer, and lung cancer with (N = 90) and without (N = 90) BM were retrospectively identified from the supportive care database for study. Descriptive statistics were used to analyze demographic, disease, and clinical data. Kaplan Meier method was used to evaluate survival outcomes.

RESULTS

While physical symptom management was the most common reason for referral to supportive care for both patients with and without BM, patients with BM had significantly lower pain scores on ESAS at time of referral (p = 0.002). They had greater interaction with acute care in the last weeks of life, with higher rates of ICU admission, emergency room visits, and hospitalizations after initial supportive care (SC) visit. The median survival time from referral to Supportive Care Center (SCC) was 0.90 years (95% CI 0.73, 1.40) for the brain metastasis group and 1.29 years (95% CI 0.91, 2.29) for the group without BM.

CONCLUSIONS

Patients with BM have shorter survival and greater interaction with acute care in the last weeks of life. This population also has distinct symptom burdens from patients without BM. Strategies to optimize integration of SC for patients with BM warrant ongoing study.

Inflammatory Breast Cancer: Understanding the Patient Experience

BACKGROUND

Inflammatory breast cancer (IBC) is an aggressive, locally advanced cancer with a 5-year survival rate of approximately 40%. Although patients with IBC likely experience significant and variable symptom burden from diagnosis through survivorship, the description of the symptom burden in this population is limited.

OBJECTIVES

The purpose of this study was to describe the experience of patients with IBC and define the content domain for a patient-reported outcome measure of IBC symptom burden.

METHODS

Twenty patients with IBC described their experience in single qualitative interviews. Content analysis was used to define the symptom burden content domain. Relevance ratings by a panel of experts reduced the number of items for a preliminary patient-reported outcome symptom burden measure.

RESULTS

The mean (SD) participant age was 52.8 (12.0) years; 50.0% had distant metastatic disease, and 85.0% were currently receiving treatment. Content analysis revealed 45 symptoms, with 20 symptoms reported by greater than or equal to 20% of participants. All participants described localized disease-related symptoms. Treatment-related symptoms varied among participants based on the modalities received.

CONCLUSION

Patients with IBC experience symptom burden that is distinct from the symptom burden experienced by patients with non-IBC.

IMPLICATIONS FOR PRACTICE

Differentiating the disease-related symptoms of IBC may assist clinicians in making timely and accurate diagnoses for IBC. A disease- and treatment-specific measure of the symptom burden of IBC should be incorporated in clinical practice to allow for regular assessment and evaluation of symptom burden and implementation of evidence-based interventions for symptom management.

Long-term survivors of glioblastoma: Tumor molecular, clinical, and imaging findings

Background

Glioblastoma (GBM) is the most aggressive primary brain malignancy with <45% living a year beyond diagnosis. Previously published investigations of long-term survivors (LTS) provided clinical data but rarely incorporated a comprehensive clinical and molecular analysis. Herein, we identify clinical, imaging, molecular, and outcome features for 23 GBM-LTS patients and compare them with a matched cohort of short-term survivors (STS).

Methods

Molecularly confirmed Isocitrate Dehydrogenase (IDH) wildtype GBM patients living ≥3 years post-diagnosis (NLTS = 23) or <3 years (NSTS = 75) were identified from our Natural History study. Clinical and demographic characteristics were compared. Tumor tissue was analyzed with targeted next generation sequencing (NGS) (NLTS = 23; NSTS = 74) and methylation analysis (NLTS = 18; NSTS = 28). Pre-surgical MRI scans for a subset of LTS (N = 14) and STS control (N = 28) matched on sex, age, and extent of resection were analyzed.

Results

LTS tended to be younger. Diagnostic MRIs showed more LTS with T1 tumor hypointensity. LTS tumors were enriched for MGMTp methylation and tumor protein 53 (TP53) mutation. Three patients with classic GBM histology were reclassified based on NGS and methylation testing. Additionally, there were LTS with typical poor prognostic molecular markers.

Conclusions

Our findings emphasize that generalized predictions of prognosis are inaccurate for individual patients and underscore the need for complete clinical evaluation including molecular work-up to confirm the diagnosis. Continued accrual of patients to LTS registries that containcomprehensive clinical, imaging, tumor molecular data, and outcomes measures may pro\vide important insights about individual patient prognosis.

D-TERMINED, a phase 1 trial in newly diagnosed high-grade glioma with temozolomide, radiation, and minocycline followed by adjuvant minocycline/temozolomide

Background

Standard treatment for newly diagnosed high-grade gliomas remains suboptimal. Preclinical data indicate that mesenchymal transition and radiation resistance in glioblastoma are driven by NF-κB and microglia activation, which can be inhibited by minocycline. We assessed the safety and efficacy of minocycline combined with standard radiation and temozolomide in newly diagnosed high-grade gliomas.

Methods

Adults with newly diagnosed high-grade glioma were eligible. Minocycline was given with concurrent and adjuvant temozolomide. Minocycline doses were escalated using a 3 + 3 design and expanded to identify the maximum tolerated dose (MTD) and adverse event profile. Individual progression-free survival (PFS) was compared to predicted PFS based on RTOG RPA class using a binomial test. The relationships between mesenchymal and microglial biomarkers were analyzed with immunohistochemistry.

Results

The MTD of minocycline was 150 mg twice per day (N = 20); 1 patient (5%) experienced CTCAE grade 3 + nausea and dizziness, and 2 patients (10%) demonstrated thrombocytopenia requiring temozolomide interruptions. Twelve patients exceeded their predicted PFS (60%), which did not meet the predefined efficacy endpoint of 70%. Symptoms increased during post-radiation treatment but remained mild. No significant correlation was seen between biomarkers and PFS. Expression levels of P-p65, a marker of NF-κB activation, were correlated with the microglia marker IBA-1.

Conclusions

Minocycline at 150 mg twice per day is well tolerated with standard chemoradiation in patients with newly diagnosed high-grade gliomas. PFS was not significantly increased with the addition of minocycline when compared to historical controls. NF-κB activation correlates with microglia levels in high-grade glioma.

Landscape and impact of mind-body, cognitive-behavioral, and physical activity interventions in adolescent and adult brain tumor patients: A systematic review

Background

The use of mind-body, cognitive-behavioral, and physical activity interventions have shown efficacy for improving symptom burden and functional limitations in other cancers; however, these strategies have not been widely implemented within neuro-oncology. This systematic review describes the current landscape and the impact of these interventions on adolescent and adult patients with brain tumors, which may guide the development of future interventions.

Methods

A systematic search of PubMed, Embase, and Web of Science was performed using preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines with predefined eligibility criteria. Twenty-nine studies met the inclusion criteria and were selected for review.

Results

There was promising evidence for the feasibility and efficacy of mind-body and physical activity interventions for improving mood and quality of life, as well as enhanced physical functioning following aerobic and strength-based interventions. Results were mixed for cognitive-behavioral interventions, likely due to underpowered analyses. Interventions tested in pediatric patients also showed improvements in fatigue, mood, and quality of life, though these individuals represented a small proportion of the pooled sample.

Conclusions

Findings suggest that mind-body and physical activity interventions can improve both physical and psychological health for patients with brain tumors, though additional well-designed clinical trials are needed to better establish efficacy.

Aerobic exercise interventions to address impaired quality of life in patients with pituitary tumors

Patients with pituitary tumors may experience persistent fatigue and reduced physical activity, based on subjective measures after treatment. These symptoms may persist despite gross total resection of their tumors and biochemical normalization of pituitary function. While reduced quality of life has been commonly acknowledged in pituitary tumor patients, there is a lack of studies on what interventions may be best implemented to ameliorate these issues, particularly when hormonal levels have otherwise normalized. Aerobic exercise programs have been previously described to ameliorate symptoms of chronic fatigue and reduced physical capacity across a variety of pathologies in the literature. As such, a prescribed aerobic exercise program may be an underrecognized but potentially impactful intervention to address quality of life in pituitary tumor patients. This review seeks to summarize the existing literature on aerobic exercise interventions in patients with pituitary tumors. In addition, future areas of study are discussed, including tailoring exercise programs to the hormonal status of the patient and incorporating more objective measures in monitoring response to interventions.

Atezolizumab, vemurafenib, and cobimetinib in patients with melanoma with CNS metastases (TRICOTEL): a multicentre, open-label, single-arm, phase 2 study

BACKGROUND

Targeted therapy and immunotherapy have shown intracranial activity in melanoma with CNS metastases, but there remains an unmet need, particularly for patients with symptomatic CNS metastases. We aimed to evaluate atezolizumab in combination with cobimetinib or vemurafenib plus cobimetinib in patients with melanoma with CNS metastases.

METHODS

TRICOTEL was a multicentre, open-label, single-arm, phase 2 study done in two cohorts: a BRAFV600 wild-type cohort and a BRAFV600 mutation-positive cohort, recruited at 21 hospitals and oncology centres in Brazil, France, Germany, Hungary, Italy, Spain, and Switzerland. Eligible patients were aged 18 years or older with previously untreated metastatic melanoma, brain metastases of 5 mm or larger in at least one dimension, and an Eastern Cooperative Oncology Group performance status of 2 or less. Patients in the BRAFV600 wild-type cohort received intravenous atezolizumab (840 mg, days 1 and 15 of each 28-day cycle) plus oral cobimetinib (60 mg once daily, days 1-21). Patients in the BRAFV600 mutation-positive cohort received intravenous atezolizumab (840 mg, days 1 and 15 of each 28-day cycle) plus oral vemurafenib (720 mg twice daily) plus oral cobimetinib (60 mg once daily, days 1-21); atezolizumab was withheld in cycle 1. Treatment was continued until progression, toxicity, or death. The primary outcome was intracranial objective response rate confirmed by assessments at least 4 weeks apart, as assessed by independent review committee (IRC) using modified Response Evaluation Criteria in Solid Tumours version 1.1. Because of early closure of the BRAFV600 wild-type cohort, the primary endpoint of intracranial objective response rate by IRC assessment was not done in this cohort; intracranial objective response rate by investigator assessment was reported instead. Efficacy and safety were analysed in all patients who received at least one dose of study medication. This trial is closed to enrolment and is registered with ClinicalTrials.gov, NCT03625141.

FINDINGS

Between Dec 13, 2018, and Dec 7, 2020, 65 patients were enrolled in the BRAFV600 mutation-positive cohort; the BRAFV600 wild-type cohort was closed early after enrolment of 15 patients. Median follow-up was 9·7 months (IQR 6·3-15·0) for the BRAFV600 mutation-positive cohort and 6·2 months (3·5-23·0) for the BRAFV600 wild-type cohort. Intracranial objective response rate was 42% (95% CI 29-54) by IRC assessment in the BRAFV600 mutation-positive cohort and 27% (95% CI 8-55) by investigator assessment in the BRAFV600 wild-type cohort. Treatment-related grade 3 or worse adverse events occurred in 41 (68%) of 60 patients who received atezolizumab plus vemurafenib plus cobimetinib in the BRAFV600 mutation-positive cohort, the most common of which were lipase increased (15 [25%] of 60 patients) and blood creatine phosphokinase increased (11 [18%]). Eight (53%) of 15 patients treated with atezolizumab plus cobimetinib in the BRAFV600 wild-type cohort had treatment-related grade 3 or worse adverse events, most commonly anaemia (two [13%]) and dermatitis acneiform (two [13%]). Treatment-related serious adverse events occurred in 14 (23%) of 60 patients who received triplet therapy in the BRAFV600 mutation-positive cohort and two (13%) of 15 in the BRAFV600 wild-type cohort. No treatment-related deaths occurred.

INTERPRETATION

Atezolizumab plus vemurafenib and cobimetinib provided intracranial activity in patients with BRAFV600-mutated melanoma with CNS metastases.

Pertuzumab plus high-dose trastuzumab for HER2-positive breast cancer with brain metastases: PATRICIA final efficacy data

The PATRICIA study (NCT02536339) examined the efficacy and safety of pertuzumab plus high-dose trastuzumab in patients with HER2-positive metastatic breast cancer (MBC) with progressive central nervous system (CNS) metastases following radiotherapy. Primary analysis confirmed CNS objective response rate (ORR) was 11% (95% confidence interval [CI]: 3-25); clinical benefit rate (CBR) was 68% (4 months) and 51% (6 months). We report final efficacy data after a further 21-months of follow-up, updated safety, survival, and patient-reported outcomes (PROs). Patients received standard-dose pertuzumab plus high-dose trastuzumab (6 mg/kg weekly) until CNS or systemic disease progression or unacceptable toxicity. Primary endpoint: confirmed ORR (CNS) per Response Assessment in Neuro-Oncology Brain Metastases criteria. Secondary endpoints were response duration, CBR, progression-free survival (PFS), overall survival (OS), safety, and PROs. By clinical cut-off, 39 patients had completed or discontinued treatment. Confirmed ORR (CNS) was 11% (95% CI: 3.0-25.4). Median CNS-PFS was 4.6 months (95% CI: 4.0-8.9), as was median CNS-PFS or systemic PFS (95% CI: 4.0-8.9); median OS was 27.2 months (95% CI: 16.1-not reached). CBR in the CNS was 51% (19 patients, 95% CI: 34.4-68.1) at 6 months. Two patients remained on treatment until study closure, achieving stable disease for 4.1 and 4.8 years. Treatment-related grade 3/4 adverse events occurred in 7.7% of patients. Patients with confirmed partial response or stable disease (≥4 months) in the CNS had stable PROs over time. Pertuzumab plus high-dose trastuzumab represents a reasonable non-chemotherapeutic treatment option for selected patients with HER2-positive MBC with CNS metastases.

Sustained Preservation of Cognition and Prevention of Patient-Reported Symptoms With Hippocampal Avoidance During Whole-Brain Radiation Therapy for Brain Metastases: Final Results of NRG Oncology CC001

PURPOSE

Initial report of NRG Oncology CC001, a phase 3 trial of whole-brain radiation therapy plus memantine (WBRT + memantine) with or without hippocampal avoidance (HA), demonstrated neuroprotective effects of HA with a median follow-up of fewer than 8 months. Herein, we report the final results with complete cognition, patient-reported outcomes, and longer-term follow-up exceeding 1 year.

METHODS AND MATERIALS

Adult patients with brain metastases were randomized to HA-WBRT + memantine or WBRT + memantine. The primary endpoint was time to cognitive function failure, defined as decline using the reliable change index on the Hopkins Verbal Learning Test-Revised (HVLT-R), Controlled Oral Word Association, or the Trail Making Tests (TMT) A and B. Patient-reported symptom burden was assessed using the MD Anderson Symptom Inventory with Brain Tumor Module and EQ-5D-5L.

RESULTS

Between July 2015 and March 2018, 518 patients were randomized. The median follow-up for living patients was 12.1 months. The addition of HA to WBRT + memantine prevented cognitive failure (adjusted hazard ratio, 0.74, P = .016) and was associated with less deterioration in TMT-B at 4 months (P = .012) and HVLT-R recognition at 4 (P = .055) and 6 months (P = .011). Longitudinal modeling of imputed data showed better preservation of all HVLT-R domains (P < .005). Patients who received HA-WBRT + Memantine reported less symptom burden at 6 (P < .001 using imputed data) and 12 months (P = .026 using complete-case data; P < .001 using imputed data), less symptom interference at 6 (P = .003 using complete-case data; P = .0016 using imputed data) and 12 months (P = .0027 using complete-case data; P = .0014 using imputed data), and fewer cognitive symptoms over time (P = .043 using imputed data). Treatment arms did not differ significantly in overall survival, intracranial progression-free survival, or toxicity.

CONCLUSIONS

With median follow-up exceeding 1 year, HA during WBRT + memantine for brain metastases leads to sustained preservation of cognitive function and continued prevention of patient-reported neurologic symptoms, symptom interference, and cognitive symptoms with no difference in survival or toxicity.

The Mediating Effect of Uncertainty in Illness on Cancer Coping in Patients With Primary Malignant Brain Tumors

BACKGROUND

Patients with primary malignant brain tumors (PMBTs) experience uncertainty in illness (UI) because of the high recurrence rate and symptoms that occur during treatment.

OBJECTIVE

To develop and test a model based on the Uncertainty in Illness Theory to predict the UI and cancer coping experienced by PMBT patients.

METHODS

This was a cross-sectional study using path analysis. The participants were adults diagnosed with PMBT who completed a questionnaire about demographic and disease-related characteristics, UI, cancer coping, brain tumor symptoms, and social support. Clinical data (eg, the diagnosis, tumor location, and grade) were obtained from electronic health records. Data were analyzed using SPSS 26.0 and the MVN , psych , and lavaan packages in R 4.1.0.

RESULTS

This study included 203 PMBT patients. The hypothesized model satisfied all statistical criteria (comparative fit index = 0.998, root mean square error of approximation = 0.044, standardized root mean square residual = 0.016). The indirect and direct associations of UI in the path from social support to cancer coping were all significant with a 95% bootstrapping confidence interval. Although the indirect and direct associations of UI in the path of brain tumor symptoms and cancer coping did not have direct or total effects, the indirect effect was statistically significant.

CONCLUSIONS

Uncertainty in illness mediated brain tumor symptoms and social support to predict cancer coping.

IMPLICATIONS FOR PRACTICE

A nurse-led intervention for cancer coping among PMBT patients can be developed by considering symptoms and social support and UI as a mediator.

Identification of health-related quality of life profiles among long-term survivors of primary central nervous system tumors

PURPOSE

We aimed to identify health-related quality of life (HRQOL) latent classes among primary central nervous system tumor (PCNST) long-term survivors (LTS) and to evaluate differences between classes in survivor sociodemographic characteristics, clinical characteristics, and symptoms to guide  the development of survivorship care programs tailored to unique class needs.

METHODS

Data from 298 PCNST LTS reporting HRQOL on the EQ-5D-3L were analyzed using latent profile analysis. Correlations and independent group t-tests were performed to identify differences between identified HRQOL classes by sociodemographic, clinical characteristics, and symptoms.

RESULTS

Sample mean age was 48 years, 54% were male, 82% Caucasian, 56% employed, 60% had a high-grade glioma, and 52% had a KPS ≥ 90. Two HRQOL classes, good (61%) and poor (39%), were identified. The good HRQOL class reported no problems with self-care and few problems with mobility or usual activities. Thirty-eight percent reported anxiety and depression and 21% pain. Over 94% of the poor HRQOL class had at least moderate problems with mobility and usual activities, and over 50% had pain, self-care issues, anxiety, and depression. Older age (φ = 0.21), unemployment (φ = 0.30), spine tumors (φ = 0.18), active treatment (φ = 0.20), tumor recurrence (φ = 0.28), and poorer KPS scores (φ = 0.61) were associated with membership in the poor HRQOL class.

CONCLUSIONS

In the poor PCNST LTS HRQOL class, an overwhelming majority faced significant physical challenges, and the good HRQOL class experienced mood-related disturbance but limited physical challenges. These HRQOL profiles can be used to guide survivorship programs and tailored interventions.

Disease Assessments in Patients with Glioblastoma

PURPOSE OF REVIEW

The neuro-oncology team faces a unique challenge when assessing treatment response in patients diagnosed with glioblastoma. Magnetic resonance imaging (MRI) remains the standard imaging modality for measuring therapeutic response in both clinical practice and clinical trials. However, even for the neuroradiologist, MRI interpretations are not straightforward because of tumor heterogeneity, as evidenced by varying degrees of enhancement, infiltrating tumor patterns, cellular densities, and vasogenic edema. The situation is even more perplexing following therapy since treatment-related changes can mimic viable tumor. Additionally, antiangiogenic therapies can dramatically decrease contrast enhancement giving the false impression of decreasing tumor burden. Over the past few decades, several approaches have emerged to augment and improve visual interpretation of glioblastoma response to therapeutics. Herein, we summarize the state of the art for evaluating the response of glioblastoma to standard therapies and investigational agents as well as challenges and future directions for assessing treatment response in neuro-oncology.

RECENT FINDINGS

Monitoring glioblastoma responses to standard therapy and novel agents has been fraught with many challenges and limitations over the past decade. Excitingly, new promising methods are emerging to help address these challenges. Recently, the Response Assessment in Neuro-Oncology (RANO) working group proposed an updated response criteria (RANO 2.0) for the evaluation of all grades of glial tumors regardless of IDH status or therapies being evaluated. In addition, advanced neuroimaging techniques, such as histogram analysis, parametric response maps, morphometric segmentation, radio pharmacodynamics approaches, and the integrating of amino acid radiotracers in the tumor evaluation algorithm may help resolve equivocal lesion interpretations without operative intervention. Moreover, the introduction of other techniques, such as liquid biopsy and artificial intelligence could complement conventional visual assessment of glioblastoma response to therapies. Neuro-oncology has evolved over the past decade and has achieved significant milestones, including the establishment of new standards of care, emerging therapeutic options, and novel clinical, translational, and basic research. More recently, the integration of histopathology with molecular features for tumor classification has marked an important paradigm shift in brain tumor diagnosis. In a similar manner, treatment response monitoring in neuro-oncology has made considerable progress. While most techniques are still in their inception, there is an emerging body of evidence for clinical application. Further research will be critically important for the development of impactful breakthroughs in this area of the field.

Frequency and burden of potentially treatable symptoms in glioma patients with stable disease

Background & aims

Glioma patients experience a multitude of symptoms that negatively affect their health-related quality of life. Symptoms vary greatly across disease phases, and the patients' stable phase might be particularly suitable for assessing and treating symptoms. Identifying symptoms and patients' needs is a first step toward improving patient care. In glioma patients with stable disease, we assessed the frequency and burden of patient-reported symptoms, examined how these symptoms co-occur, and also determined whether patients would consider treatment to ameliorate specific symptoms.

Methods

In this retrospective study, patients rated the frequency and burden of seventeen symptoms on a seven-point Likert scale and stated whether they would consider treatment for these symptoms. Correlations between frequency, burden, and considering treatment were evaluated with Kendall's Tau correlation coefficients. Based on partial correlations between symptom frequencies we visualized the symptoms as a network.

Results

Fifty-two glioma patients with stable disease were included (31 WHO grade II/III, 21 WHO grade IV). The top five symptoms were fatigue, memory problems, reduced physical fitness, concentration problems, and drowsiness. Fatigue had the highest median frequency (4.5, interquartile range 2.5). Over half of the patients experienced three or more symptoms simultaneously and associations between all symptoms were depicted as a network. Overall, 35% of patients would consider treatment for at least one symptom. The wish to undergo symptom treatment correlated only moderately with symptom frequency and burden (range of correlations 0.24-0.57 and 0.28-0.61, respectively).

Conclusion

Glioma patients with stable disease experience multiple symptoms with a consequently high symptom burden. Despite the high prevalence of symptoms, the inclination for symptom management interventions was relatively low. The most frequent and burdensome symptoms and the way they are interrelated could serve as a roadmap for future research on symptom management in these patients.

Heterogeneous clinicopathological findings and patient-reported outcomes in adults with MN1-altered CNS tumors: A case report and systematic literature review

The uncommon MN1-altered primary central nervous system (CNS) tumors were recently added to the World Health Organization 2021 classification under the name Astroblastoma, MN1-altered. Another term used to describe them, "High-grade neuroepithelial tumor with MN1 alteration" (HGNET-MN1), makes reference to their distinct epigenetic profile but is currently not a recommended name. Thought to occur most commonly in children and predominantly in females, MN1-altered CNS tumors are associated with typical but not pathognomonic histological patterns and are characterized by a distinct DNA methylation profile and recurrent fusions implicating the MN1 (meningioma 1) gene. Diagnosis based on histological features alone is challenging: most cases with morphological features of astroblastoma (but not all) show these molecular features, whereas not all tumors with MN1 fusions show astroblastoma morphology. There is large variability in reported outcomes and detailed clinical and therapeutic information is frequently missing. Some patients experience multiple recurrences despite multimodality treatment, whereas others experience no recurrence after surgical resection alone, suggesting large clinical and biological heterogeneity despite unifying epigenetic features and recurrent fusions. In this report, we present the demographics, tumor characteristics, treatment, and outcome (including patient-reported outcomes) of three adults with MN1-altered primary CNS tumors diagnosed via genome-wide DNA methylation and RNA sequencing. All three patients were females and two of them were diagnosed as young adults. By reporting our neuropathological and clinical findings and comparing them with previously published cases we provide insight into the clinical heterogeneity of this tumor. Additionally, we propose a model for prospective, comprehensive, and systematic collection of clinical data in addition to neuropathological data, including standardized patient-reported outcomes.

IMPACT the Brain: A Team-Based Approach to Management of Metastatic Breast Cancer With CNS Metastases

PURPOSE

CNS metastases are associated with decreased survival and quality of life for patients with metastatic breast cancer (MBC). Team-based care can optimize outcomes. IMPACT the Brain is a care coordination program that aims to improve access to team-based care for patients with MBC and CNS metastases.

MATERIALS AND METHODS

Patients with MBC and CNS metastases were eligible for enrollment in this care coordination program. A team of specialists supported a dedicated program coordinator who provided navigation, education, specialty referral, and clinical trial screening. A unique intake form developed for the program created personalized, coordinated, and expedited specialty referrals. Patient-reported outcomes and caregiver burden assessments were collected on a voluntary basis throughout enrollment. Data were analyzed using descriptive statistics.

RESULTS

Sixty patients were referred, and 53 were enrolled (88%). The median time to program enrollment was 1 day (range, 0-11) and to first visit was 5 days (range, 0-25). On the basis of the program intake form, 47 referrals were made across six specialties, most commonly physical medicine and rehabilitation (n = 10), radiation oncology (n = 10), and neuropsychology (n = 10). Nineteen patients (36%) consented to enroll in clinical trials.

CONCLUSION

A tailored team-based care coordination program for patients with MBC and CNS metastases is feasible. Use of a unique intake screening form by a dedicated program coordinator resulted in faster time to first patient visit, enabled access to subspecialist care, and supported enrollment in clinical trials. Future research should focus on intervention development using PRO data collected in this care coordination program.

Predictive models and survival analysis of postoperative mental health disturbances in adult glioma patients

Background and Objectives

Patients with primary malignant brain tumors may experience mental health disturbances that can significantly affect their daily life. This study aims to identify risk factors and generate predictive models for postoperative mental health disturbances (PMHDs) in adult glioma patients in accordance with different clinical periods; additionally, survival analyses will be performed.

Methods

This longitudinal cohort study included 2,243 adult patients (age at diagnosis ≥ 18 years) with nonrecurrent glioma who were pathologically diagnosed and had undergone initial surgical resection. Six indicators of distress, sadness, fear, irritability, mood and enjoyment of life, ranging from 0-10, were selected to assess PMHDs in glioma patients in the third month after surgery, mainly referring to the M.D. Anderson Symptom Inventory Brain Tumor Module (MDASI-BT). Factor analysis (FA) was applied on these indicators to divide participants into PMHD and control groups based on composite factor scores. Survival analyses were performed, and separate logistic regression models were formulated for preoperative and postoperative factors predicting PMHDs.

Results

A total of 2,243 adult glioma patients were included in this study. Based on factor analysis results, 300 glioma patients had PMHDs in the third postoperative month, and the remaining 1,943 were controls. Candidate predictors for PMHDs in the preoperative model were associated with age, clinical symptoms (intracranial space-occupying lesion, muscle weakness and memory deterioration), and tumor location (corpus callosum, basal ganglia and brainstem), whereas age, clinical symptoms (nausea and memory deterioration), tumor location (basal ganglia and brainstem), hospitalization days, WHO grade 4, postoperative chemotherapy or radiotherapy and postoperative Karnofsky Performance Scale (KPS) served as important factors in the postoperative model. In addition, the median overall survival (OS) time for glioma patients with PMHDs was 19 months, compared to 13 months for glioblastoma, IDH-wild type (GBM) patients with PMHDs.

Conclusion

The risk factors for PMHDs were identified. These findings may provide new insights into predicting the probability of PMHD occurrence in glioma patients in addition to aiding effective early intervention and improving prognosis based on different clinical stages.

Development of a core outcome set for use in adult primary glioma phase III interventional trials: A mixed methods study

Background

Glioma interventional studies should collect data aligned with patient priorities, enabling treatment benefit assessment and informed decision-making. This requires effective data synthesis and meta-analyses, underpinned by consistent trial outcome measurement, analysis, and reporting. Development of a core outcome set (COS) may contribute to a solution.

Methods

A 5-stage process was used to develop a COS for glioma trials from the UK perspective. Outcome lists were generated in stages 1: a trial registry review and systematic review of qualitative studies and 2: interviews with glioma patients and caregivers. In stage 3, the outcome lists were de-duplicated with accessible terminology, in stage 4 outcomes were rated via a 2-round Delphi process, and stage 5 comprised a consensus meeting to finalize the COS. Patient-reportable COS outcomes were identified.

Results

In Delphi round 1, 96 participants rated 35 outcomes identified in stages 1 and 2, to which a further 10 were added. Participants (77/96) rated the resulting 45 outcomes in round 2. Of these, 22 outcomes met a priori threshold for inclusion in the COS. After further review, a COS consisting of 19 outcomes grouped into 7 outcome domains (survival, adverse events, activities of daily living, health-related quality of life, seizure activity, cognitive function, and physical function) was finalized by 13 participants at the consensus meeting.

Conclusions

A COS for glioma trials was developed, comprising 7 outcome domains. Additional research will identify appropriate measurement tools and further validate this COS.

Relationship between RANO-PRO Working Group standardised priority constructs and disease progression among malignant glioma patients: A retrospective cohort study

BACKGROUND

Recognising the importance of clinical outcomes assessments (COAs), the Response Assessment in Neuro-Oncology-Patient Reported Outcome (RANO-PRO) Working Group recommended inclusion of core symptoms and functions in clinical care or research for malignant glioma patients. This study evaluated the association of the recommended symptoms (pain, perceived cognition, seizures, aphasia, symptomatic adverse events) and functions (weakness, walking, work, usual activities) with disease progression in these patients.

METHODS

In this retrospective cohort study, patients with malignant glioma were included from the US National Cancer Institute Neuro-Oncology Branch Natural History Study (NOB-NHS) which follows primary central nervous system tumour patients aged 18 years and older throughout their disease trajectory. The M.D. Anderson Symptom Inventory-Brain Tumor (MDASI-BT), EQ-5D-3L, Karnofsky Performance Status (KPS), and Neurologic Function scores (NFS) were evaluated in relation to disease progression by chi-square tests, independent- and paired-samples t-tests, adjusted for multiple comparisons at first assessment and over time to a second assessment. Radiographic disease progression was determined on the interpretation of the imaging study by a radiologist and neuro-oncologist using standard criteria as part of clinical trial participation or routine standard of care. The priority constructs were evaluated to provide initial evidence of their relevance, relationship to disease status over time, and sensitivity to change in a diverse group of patients with malignant glioma.

FINDINGS

Seven hundred and sixty-five patients had enrolled into the NOB-NHS between September 1, 2016 and January 31, 2020. Three hundred and thirty-six patients had a diagnosis of a malignant glioma (anaplastic astrocytoma, anaplastic oligodendroglioma, glioblastoma, and gliosarcoma) and were included in the current study. The sample was 64% male (n = 215), 36% female (n = 121), median age of 52 years (IQR = 18.75), 82% White (n = 276), and 65% had tumour recurrence (n = 219). One hundred and fifty-four (46%) had radiographic disease progression. Difficulty remembering, fatigue, and weakness were worse in the group whose imaging was interpreted as radiographic disease progression versus stable disease, as well as the functions of walking, work, activity, and self-care (1.1 < difference < 1.8). Patients with disease progression were four times more likely to have a poor KPS (≤80) and worse NFS. Among patients with disease progression at a second assessment (n = 112), all symptoms, except seizures, worsened between first assessment and disease progression and up to 22% of patients (n = 25) reported worsening mobility, self-care, and usual activity; 46% (n = 51) and 35% (n = 30) had worsened KPS and NFS, respectively. On average, 4 symptoms or functions (SD = 3) were reported as moderate-to-severe and 30% (n = 33) and 23% (n = 26) had a change to moderate-to-severe fatigue and walking, respectively, at time of disease progression. Over 7% of patients with worsening (n = 7 of 100) reported every symptom and function as having changed the most severely including seizures with fatigue and activity reported as the top symptom and function, respectively.

INTERPRETATION

The identified core symptoms and functions worsened at the time of progression, supporting the relevance and sensitivity of the priority constructs identified by the RANO-PRO Working Group for clinical care and clinical trials for malignant glioma patients.

Surveillance of long-term complications after treatment of adult brain tumor survivors-review and evidence-based recommendations

As a result of treatment and diagnosis, adults with primary or metastatic brain tumors experience comorbidities that impacts their health and well-being. The Children's Oncology Group has guideline recommendations for childhood survivors of brain tumors; however, guidelines for monitoring long-term sequela among adult brain tumor survivors are lacking. The purpose of this review is to present the screening recommendations for the long-term complications after brain tumor treatment from a multidisciplinary panel of healthcare professionals. Chronic complications identified include cognitive dysfunction, vasculopathy, endocrinopathy, ophthalmic, ototoxicity, physical disability, sleep disturbance, mood disorder, unemployment, financial toxicity, and secondary malignancy. We invited specialists across disciplines to perform a literature search and provide expert recommendations for surveillance for long-term complications for adult brain tumor survivors. The Brain Tumor Center Survivorship Committee recommends routine screening using laboratory testing, subjective assessment of symptoms, and objective evaluations to appropriately monitor the complications of brain tumor treatments. Effective monitoring and treatment should involve collaboration with primary care providers and may require referral to other specialties and support services to provide patient-centered care during neuro-oncology survivorship. Further research is necessary to document the incidence and prevalence of medical complications as well as evaluate the efficacy of screening and neuro-oncology survivorship programs.

Exploring the prevalence and burden of sleep disturbance in primary brain tumor patients

BACKGROUND

Sleep disturbance (SD) is common in patients with cancer and has been associated with worse clinical outcomes. This cross-sectional study explored the prevalence of SD in a primary brain tumor (PBT) population, identified associated demographic and clinical characteristics, and investigated co-occurrence of SD with other symptoms and mood disturbance.

METHODS

Demographic, clinical characteristics, MD Anderson Symptom Inventory-Brain Tumor, and Patient Reported Outcome Measurement Information System Depression and Anxiety Short-Forms were collected from PBT patients at study entry. Descriptive statistics, Chi-square tests, and independent t-tests were used to report results.

RESULTS

The sample included 424 patients (58% male, 81% Caucasian) with a mean age of 49 years (range 18-81) and 58% with high-grade gliomas. Moderate-severe SD was reported in 19% of patients and was associated with younger age, poor Karnofsky Performance Status, tumor progression on MRI, and active corticosteroid use. Those with moderate-severe SD had higher overall symptom burden and reported more moderate-severe symptoms. These individuals also reported higher severity in affective and mood disturbance domains, with 3 to 4 times higher prevalence of depressive and anxiety symptoms, respectively. The most frequently co-occurring symptoms with SD were, drowsiness, and distress, though other symptoms typically associated with tumor progression also frequently co-occurred.

CONCLUSIONS

PBT patients with moderate-severe SD are more symptomatic, have worse mood disturbance, and have several co-occurring symptoms. Targeting interventions for sleep could potentially alleviate other co-occurring symptoms, which may improve life quality for PBT patients. Future longitudinal work examining objective and detailed subjective sleep reports, as well as underlying genetic risk factors, will be important.

Novel Clinical Trial Designs in Neuro-Oncology

Scientific and technologic advances have led to a boon of candidate therapeutics for patients with malignancies of the central nervous system. The path from drug development to clinical use has generally followed a regimented order of sequential clinical trial phases. The recent increase in novel therapies, however, has strained the regulatory process and unearthed limitations of the current system, including significant cost, prolonged development time, and difficulties in testing therapies for rarer tumors. Novel clinical trial designs have emerged to increase efficiencies in clinical trial conduct to better evaluate and bring impactful drugs to patients in a timely manner. In order to better capture meaningful benefits for brain tumor patients, new endpoints to complement or replace traditional endpoints are also an increasingly important consideration. This review will explore the current challenges in the current clinical trial landscape and discuss novel clinical trial concepts, including consideration of limitations and risks of novel trial designs, within the context of neuro-oncology.

Interventions for the management of fatigue in adults with a primary brain tumour

BACKGROUND

Fatigue is a common and disabling symptom in people with a primary brain tumour (PBT). The effectiveness of interventions for treating clinically significant levels of fatigue in this population is unclear. This is an updated version of the original Cochrane Review published in Issue 4, 2016.

OBJECTIVES

To assess the effectiveness and safety of pharmacological and non-pharmacological interventions for adults with PBT and clinically significant (or high levels) of fatigue.

SEARCH METHODS

For this updated review, we searched CENTRAL, MEDLINE and Embase, and checked the reference lists of included studies in April 2022. We also searched relevant conference proceedings, and ClinicalTrials.gov for ongoing trials.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that investigated any pharmacological or non-pharmacological intervention in adults with PBT and fatigue, where fatigue was the primary outcome measure. We restricted inclusion specifically to studies that enrolled only participants with clinically significant levels of fatigue to improve the clinical utility of the findings.

DATA COLLECTION AND ANALYSIS

Two review authors (JD, DC) independently evaluated search results for the updated search. Two review authors (JD, SYK) extracted data from selected studies, and carried out a risk of bias assessment. We extracted data on fatigue, mood, cognition, quality of life and adverse events outcomes.

MAIN RESULTS

The original review identified one study and this update identified a further two for inclusion. One study investigated the use of modafinil, one study the use of armodafinil and one study the use of dexamfetamine. We identified three ongoing studies. In the original review, the single eligible trial compared modafinil to placebo for 37 participants with a high- or low-grade PBT. One new study compared two doses of armodafinil (150 mg and 250 mg) to placebo for 297 people with a high-grade glioma. The second new study compared dexamfetamine sulfate to placebo for 46 participants with a low- or high-grade PBT. The evidence was uncertain for both modafinil and dexamfetamine regarding fatigue outcome measures, compared to controls, at study endpoint. Two trials did not reach the planned recruitment target and therefore may not, in practice, have been adequately powered to detect a difference. These trials were at a low risk of bias across most areas. There was an unclear risk of bias related to the use of mean imputation for one study because the investigators did not analyse the impact of imputation on the results and information regarding baseline characteristics and randomisation were not clear. The certainty of the evidence measured using GRADE was very low across all three studies. There was one identified study awaiting classification once data are available, which investigated the feasibility of 'health coaching' for people with a PBT experiencing fatigue. There were three ongoing studies that may be eligible for an update of this review, all investigating a non-pharmacological intervention for fatigue in people with PBT.

AUTHORS' CONCLUSIONS

There is currently insufficient evidence to draw reliable and generalisable conclusions regarding potential effectiveness or harm of any pharmacological or non-pharmacological treatments for fatigue in people with PBT. More research is needed on how best to treat people with brain tumours with high fatigue.

Factors Predicting Frailty Among Postoperative Brain Tumor Patients

ABSTRACT

BACKGROUND: Surgical frailty is a condition in which patients are weak with varied recovery of various organ functions after surgery resulting in unpleasant outcomes. Frailty studies have been conducted in several populations with a limited knowledge on postoperative brain tumor patients. This study aimed to examine factors predicting frailty in brain tumor patients after craniotomy. METHODS: This study was a cross-sectional predictive study. The sample included 85 patients who were 18 years or older and underwent craniotomy with tumor removal from 1 university hospital in Bangkok, Thailand, between February and October 2021. Data were analyzed using descriptive statistic, Pearson correlation, and multiple linear regression, which determined significance level at .05. RESULTS: The prevalence of frailty among participants was 50.6%. Postoperative symptom and mood state were positively associated with frailty (r = 0.410 and r = 0.448, respectively; P < .01). Postoperative symptom, mood state, age, tumor type, and income could explain the variance of frailty in brain tumor patients after craniotomy by 40.3% (R2 = 0.403, P < .01). CONCLUSION: Healthcare providers should plan for discharge planning including assessment and develop the intervention for managing postoperative symptoms and psychological symptoms to promote recovery from frailty that generally occurs after brain tumor surgery.

Evaluation of the key geriatric assessment constructs in primary brain tumor population - a descriptive study

INTRODUCTION

Despite an increasing aging population, older adults (≥ 65 years) with primary brain tumors (PBTs) are not routinely assessed for geriatric vulnerabilities. Recent reports of geriatric assessment (GA) in patients with glioblastomas demonstrated that GA may serve as a sensitive prognosticator of overall survival. Yet, current practice does not include routine evaluation of geriatric vulnerabilities and the relevance of GA has not been previously evaluated in broader cohorts of PBT patients. The objective of this descriptive study was to assess key GA constructs in adults with PBT dichotomized into older versus younger groups.

MATERIALS AND METHODS

A cross-sectional analysis of data collected from 579 participants with PBT recruited between 2016 and 2020, dichotomized into older (≥ 65 years, n = 92) and younger (≤ 64 years, n = 487) from an ongoing observational trial. GA constructs were evaluated using socio-demographic characteristics, Charlson Comorbidity Index (CCI), polypharmacy (>5 daily medications), Karnofsky Performance Status (KPS), Neurologic Function Score (NFS), and patient-reported outcome assessments including general health, functional status, symptom burden and interference, and mood. Descriptive statistics, t-tests, chi-square tests, and Pearson correlations were used to evaluate differences between age groups.

RESULTS

Older participants were more likely to have problems with mobility (58% vs. 44%), usual activities (64% vs 50%) and self-care (38% vs 26%) compared to the younger participants (odds ratios [ORs] = 1.3-1.4, ps < 0.05), while older participants were less likely to report feeling distressed (OR = 0.4, p < 0.05). Older participants also had higher CCI and were more likely to have polypharmacy (OR = 1.7, ps < 0.05). Increasing age strongly correlated with worse KPS score (r = -0.232, OR = 1.4, p < 0.001) and worse NFS (r = 0.210, OR = 1.5, p < 0.001). No differences were observed in overall symptom burden, symptom interference, and anxiety/depression scores.

DISCUSSION

While commonly used GA tools were not available, the study employed patient- and clinician-reported outcomes to identify potential future research directions for the use of GA in the broader neuro-oncology population. Findings illustrate missed opportunities in neuro-oncology practice and underscore the need for incorporation of GA into routine care of this population. Future studies are warranted to further evaluate the prognostic utility of GA and to better understand functional aging outcomes in this patient population.

Depatuxizumab mafodotin in EGFR-amplified newly diagnosed glioblastoma: A phase III randomized clinical trial

BACKGROUND

Approximately 50% of newly diagnosed glioblastomas (GBMs) harbor epidermal growth factor receptor gene amplification (EGFR-amp). Preclinical and early-phase clinical data suggested efficacy of depatuxizumab mafodotin (depatux-m), an antibody-drug conjugate comprised of a monoclonal antibody that binds activated EGFR (overexpressed wild-type and EGFRvIII-mutant) linked to a microtubule-inhibitor toxin in EGFR-amp GBMs.

METHODS

In this phase III trial, adults with centrally confirmed, EGFR-amp newly diagnosed GBM were randomized 1:1 to radiotherapy, temozolomide, and depatux-m/placebo. Corneal epitheliopathy was treated with a combination of protocol-specified prophylactic and supportive measures. There was 85% power to detect a hazard ratio (HR) ≤0.75 for overall survival (OS) at a 2.5% 1-sided significance level (ie traditional two-sided p ≤ 0.05) by log-rank testing.

RESULTS

There were 639 randomized patients (median age 60, range 22-84; 62% men). Prespecified interim analysis found no improvement in OS for depatux-m over placebo (median 18.9 vs. 18.7 months, HR 1.02, 95% CI 0.82-1.26, 1-sided p = 0.63). Progression-free survival was longer for depatux-m than placebo (median 8.0 vs. 6.3 months; HR 0.84, 95% confidence interval [CI] 0.70-1.01, p = 0.029), particularly among those with EGFRvIII-mutant (median 8.3 vs. 5.9 months, HR 0.72, 95% CI 0.56-0.93, 1-sided p = 0.002) or MGMT unmethylated (HR 0.77, 95% CI 0.61-0.97; 1-sided p = 0.012) tumors but without an OS improvement. Corneal epitheliopathy occurred in 94% of depatux-m-treated patients (61% grade 3-4), causing 12% to discontinue.

CONCLUSIONS

Interim analysis demonstrated no OS benefit for depatux-m in treating EGFR-amp newly diagnosed GBM. No new important safety risks were identified.

Initial results of a phase II trial of 18F-DOPA PET-guided re-irradiation for recurrent high-grade glioma

PURPOSE

In-field high-grade glioma (HGG) recurrence is a common challenge with limited treatment options, including re-irradiation. The radiotracer 3,4-dihydroxy-6-[18F]-fluoro-L-phenylalanine (¹⁸F-DOPA) crosses the blood brain barrier and demonstrates high uptake in tumor, but low uptake in normal tissue. This study investigated whether ¹⁸F-DOPA positron emission tomography (PET) and MRI guided re-irradiation for recurrent HGG may improve progression free survival (PFS).

METHODS

Adults with recurrent or progressive HGG previously treated with radiation were eligible. The primary endpoint was a 20% improvement from the historical control PFS at 3 months (PFS3) of 20% with systemic therapy alone. Re-RT dose was 35 Gy in 10 fractions. The target volume was MRI T1 contrast-enhancement defined tumor plus ¹⁸F-DOPA PET defined tumor.

RESULTS

Twenty patients completed treatment per protocol. Diagnosis was most commonly glioblastoma, IDH-wildtype (60%). MRI-defined volumes were expanded by a median 43% (0-436%) by utilizing ¹⁸F-DOPA PET. PFS3 was 85% (95% CI 63.2-95.8%), meeting the primary endpoint of PFS3 ≥ 40%. With 9.7 months median follow-up, 17 (85%) had progressed and 15 (75%) had died. Median OS from re-RT was 8.8 months. Failure following re-RT was within both the MRI and PET tumor volumes in 75%, MRI only in 13%, PET only in 0%, and neither in 13%. Four (20%) patients experienced grade 3 toxicity, including CNS necrosis (n = 2, both asymptomatic with bevacizumab initiation for radiographic findings), seizures (n = 1), fatigue (n = 1), and nausea (n = 1). No grade 4-5 toxicities were observed.

CONCLUSION

¹⁸F-DOPA PET-guided re-irradiation for progressive high-grade glioma appears safe and promising for further investigation.

The Montreal Cognitive Assessment (MoCA) in Neuro-Oncology: A Pilot Study of Feasibility and Utility in Telehealth and In-Person Clinical Assessments

Background

Cognitive impairments are a common burden for patients with primary CNS tumors. Neuropsychological assessment batteries can be too lengthy, which limits their use as an objective measure of cognition during routine care. The purpose of this study was to evaluate the feasibility and utility of the brief Montreal Cognitive Assessment (MoCA) in routine in-person and telehealth visits (as a result of the global COVID-19 pandemic) with neuro-oncology patients.

Methods

71 adults with primary CNS tumors completed MoCA testing in-person (n=47) and via telehealth (n=24). Patient-reported outcomes (PROs), including symptom burden and interference, perceived cognition, general health status, and anxiety and depression, were and correlation analysis were included in this study. Feasibility was assessed through a provider satisfaction questionnaire.

Results

Patients were primarily White (83%), college-educated (71%) males (54%) with high grade tumors (66%). The average total score on the MoCA administered in-person was 25 (range: 6-30), with 34% classified as abnormal, and the average total score via telehealth was 26 (range: 12-30), with 29% classified as abnormal. Providers reported satisfaction in using the MoCA during routine clinical care, both in-person and via telehealth. Lower MoCA scores correlated with worse symptom severity, KPS, age, education, and previous treatment.

Conclusions

The MoCA was feasible in clinical and telehealth settings, and its relationship to clinical characteristics and PROs highlight the need for both objective and patient-reported measures of cognition to understand the overall cognitive profile of a patient with a CNS tumor.
