Predictors of self-reported word-finding difficulties in glioma patients – a longitudinal study

ABSTRACT Background Word-finding difficulties are a common self-reported concern in glioma patients known to negatively affect social participation and life satisfaction. Discrepancies between self-reported difficulties and performance on objective tests have been reported, but studies are seldom conducted longitudinally. Aims The aim of the present study was to examine the occurrence of self-reported word-finding difficulties before and during the first year after glioma surgery. In addition, we investigated whether self-reported word-finding difficulties were predicted by standardized language tests and psychological distress. Methods and procedures Twenty-three patients with gliomas (grade 1–3) were assessed pre-surgery, at six and twelve months follow-up. Self-reported word-finding difficulties were addressed with the item I am able to find the right word(s) to say what I mean, from the Functional Assessment of Cancer Therapy – Brain (FACT-Br). Confrontation naming was tested with the Boston Naming Test (BNT), word production with a semantic fluency test and word knowledge with a vocabulary test. Self-reported measures of psychological distress were assessed with the Hospital Anxiety and Depression Scale (HADS). Ordinal regression models were used to examine predictors of self-reported word-finding difficulties. Outcomes and results Word-finding difficulties were reported by 68% of the patients pre-surgery, increasing to 90% and 85% at the following assessments. Significant changes were observed in the magnitude of reported concerns between pre-surgery assessment and six months follow-up. Regression analyses demonstated that self-reported word-finding difficulties were predicted by psychological distress and vocabulary pre-surgery and vocabulary at six months follow-up, whereas confrontation naming and semantic fluency did not become significant in any of the assessments. Conclusion Our results indicate that self-reported word-finding difficulties occurred in a high percentage of glioma patients throughout the first year of illness. Patients reported increased difficulties after surgery that were not predicted by confrontation naming or semantic fluency but by vocabulary performance. The results imply further that psychological distress is a factor that should be taken into account. Self-reported function is an important supplement to objective testing and can provide indications about mental health status and the patients` perspective on language related challenges in everyday life.

NCOG-36. IMPACT OF COLLAGEN TILE BRACHYTHERAPY AS TREATMENT FOR RECURRENT GLIOBLASTOMAS ON FUNCTIONAL STATUS AND QUALITY OF LIFE

Abstract BACKGROUND Recurrent glioblastoma is an aggressive disease with dismal prognosis despite advances in standard therapy, making the maintenance of functional status and quality of life (QOL) in patients an important endpoint during treatment. Here, we report functional status (KPS) and QOL metrics (LASA and FACT-Br) at 6-months post-treatment for recurrent glioblastoma patients treated with maximal safe resection followed by intraoperative placement of collagen tile brachytherapy with Cesium-131 (Surgically Targeted Radiation Therapy or STaRT), a novel brachytherapy carrier. OBJECTIVE To assess the impact of STaRT on KPS and QOL among patients with recurrent glioblastoma (rGBM) at 6-months post-treatment. METHODS Patients were treated between 10/2020 and 05/2023 as part of a multi-institutional registry study (NCT#04427384). KPS was used to measure functional status. Linear Analog Self-Assessment (LASA) and Functional Assessment of Cancer Therapy – Brain (FACT-Br) were used to measure QOL. All assessments were collected at pre-surgery, and 1,3, and 6-months post-treatment. RESULTS 57 rGBM patients were treated on the Registry between 10/2020 and 05/2023. Of the 57 participants, 47 participants remain in the study, with 21 participants reaching the 6-month time point (5 exits, 5 deaths). Median age was 60 years (range 28-81). Methylguanine methyltransferase (MGMT) promoter was methylated in 17.5%, unmethylated in 38.5%, and unknown in 44%. Gross total resection was achieved in 72% of participants. Median KPS was 80% (range 40%-100%) at screening versus 70% (range 40%-90%) at 6 months post-treatment. Median LASA was 37 (range 8-50) at pre-surgery versus 34 (range 5-48) at 6-months post-treatment. Minimally important differences (MID) were noted between pre-surgery (136.9 ± 29.5) and 6-months post-treatment (112.5 ± 35.7) for the FACT-Br Total Score. CONCLUSION This interim data analysis supports further investigation of STaRT as a treatment for recurrent glioblastomas as a means of providing stable functional status and quality of life.

QOL-26. A RANDOMIZED, DOUBLE-BLIND PHASE 3 STUDY OF VORASIDENIB VS PLACEBO IN PATIENTS WITH MUTANT IDH1/2DIFFUSE GLIOMA (INDIGO): ANALYSIS OF HEALTH-RELATED QUALITY OF LIFE, NEUROCOGNITION AND SEIZURES

Abstract INTRODUCTION The Phase 3 INDIGO study (NCT04164901) is a randomized, double-blind evaluation of vorasidenib, an oral, brain-penetrant inhibitor of mutant isocitrate dehydrogenase (mIDH) 1/2 enzymes, compared with placebo, in patients with grade 2 mIDH1/2 diffuse gliomas, whose only prior treatment was surgery. The primary endpoint, radiographic progression-free survival by blinded independent review committee, and the key secondary endpoint, time-to-next-intervention, were significantly improved with vorasidenib versus placebo. As these patients are young, with several years’ life expectancy, impact of treatments on health-related quality of life (HRQoL), cognition and symptomatic burden is of interest. METHODS HRQoL, assessed by Functional Assessment of Cancer Therapy-Brain (FACTBr) questionnaire, was a secondary endpoint. FACT-Br was collected at baseline, Cycles 2 and 3, then every 3 months. Scores were interpreted using an estimate of clinically meaningful deterioration change from baseline for each arm. Exploratory endpoints included neurocognitive function, assessed by a validated battery of cognitive performance instruments, and seizure frequency and severity, assessed using a subject diary. RESULTS 331 patients were randomized to vorasidenib (n = 168) or placebo (n = 163) (median age, 40.0 years; Karnofsky performance scale = 100, 53.5%; ongoing medical history of seizures, 54.1%). Median follow-up was 14.2 months. No clinically meaningful deterioration from baseline FACT-Br total score and subscales were observed at any timepoint through the median treatment duration (Cycle 13) in either arm. At baseline, active seizures (≥ 1 seizure in the previous 30 days) were reported in 20/168 (11.9%) vorasidenib patients and 20/163 (12.3%) placebo patients. On-treatment seizure frequencies and cognition outcomes will be presented by arm. CONCLUSION INDIGO is the first randomized Phase 3 study of targeted therapy in grade 2 mIDH1/2 diffuse glioma. HRQoL, as measured by FACT-Br, was maintained during treatment with vorasidenib. These data support the clinical benefit of vorasidenib in this patient population for whom chemotherapy and radiotherapy are being delayed.

P08.08.A EXPLORATION OF SURVIVORSHIP ISSUES AND QUALITY OF LIFE IN A COHORT OF IDH MUTATED HIGH GRADE GLIOMA 5 YEARS FOLLOWING DEFINITIVE TREATMENT

Abstract BACKGROUND Approximately 2000 people are diagnosed with brain cancer in Australia each year. Compared to glioblastoma patients, the IDH-mutated high-grade glioma (IDHmHGG) is a more favourable diagnosis; better prognosis and survival outcomes. Coupled with improved treatments, the IDHmHGG cohort is living longer which means treatment side effects (eg. fatigue, cognitive deficits, physical limitations etc.) can significantly impact their quality of life in the survivorship years. Hence there is a need to identify and determine the survivorship issues most pertinent for the IDHmHGG cohort. MATERIAL AND METHODS A mixed- METHODS cross-sectional study was conducted to investigate the relationship between socio-demographic, clinical factors and quality of life in the IDHmHGG cohort. Qualitative data collection consisted of a neuro-oncology clinician focus group (n=11) regarding survivorship issues and was contrasted with semi-structured patient interviews (n=27). Quantitative data collection (n=41) involved socio-demographic questions, the Functional Assessment of Cancer Therapy - Brain (FACT-Br) tool and The Hospital Anxiety and Depression Scale (HADS). RESULTS The results indicate that marital status, employment status, and treatment complications are strongly associated with quality of life in IDHmHGG patients. Being single and unemployed is associated with lower quality of life (p<0.05). Similarly, our findings show that psychological distress, specifically the presence of anxiety and depressive symptoms, is a major factor that can negatively impact the QoL in an IDHmHGG cohort. The order of ranking between clinician and patient identified issues only matched for physical limitations (ranked 3rd). Although not matched in ranking, both groups identified cognitive function, employment, social function, isolation and mental health as commonly experienced in the survivorship years. CONCLUSION This study highlights the importance of considering socio-demographic and clinical factors in the care and support of brain cancer patients. The most important finding of this study was that being single and unemployed negatively predicted QoL. Additionally, it is notable that our results show a discrepancy between clinician identified issues and patient identified issues. This finding suggests that in order to deliver patient-centred and meaningful care, there is a need to incorporate a more patient focused perspective. Future survivorship models of care for the IDHmHGG cohort should be co-designed with patients.

Patterns and predictors of anxiety and depression symptom trajectories in patients diagnosed with primary brain tumors.

Patients with primary brain tumors (pPBTs) often exhibit heightened distress. This study assesses how symptoms of anxiety and depression change over time in pPBTs and identifies factors that may predict patients' symptom trajectories. Ninety-nine adult pPBTs completed psychosocial assessments at neuro-oncology appointments over 6-18months. Quality of life was assessed with the Functional Assessment of Cancer Therapy-Brain; symptoms of anxiety and depression were assessed with the Patient-Reported Outcomes Measurement Information System short forms. The prevalence of patients with clinically elevated symptoms and those who experienced clinically meaningful changes in symptoms throughout follow-up were examined. Linear mixed-effects models evaluated changes in symptoms over time at the group level, and latent class growth analysis (LCGA) evaluated changes in symptoms over time at the individual level. At enrollment, 51.5% and 32.3% of patients exhibited clinically elevated levels of anxiety and depression, respectively. Of patients with follow-up data (n = 74), 54.1% and 50% experienced clinically meaningful increases in anxiety and depression scores, respectively. There were no significant changes in anxiety or depression scores over time, but better physical, functional, and brain-cancer well-being predicted lower levels of anxiety and depression (p < 0.001). Five sub-groups of patients with distinct symptom trajectories emerged via LCGA. pPBTs commonly experience elevated symptoms of anxiety and depression that may fluctuate in clinically meaningful manners throughout the disease. Routine screening for elevated symptoms is needed to capture clinically meaningful changes and identify factors affecting symptoms to intervene on.

Long-term postoperative health-related quality of life in patients with subfrontal meningiomas.

Subfrontal meningiomas grow insidiously in areas with high cerebral compliance and a relative scarcity of eloquent function. Symptoms develop progressively, are nonspecific, and include anosmia, changes in personality and cognition, depressive symptoms, headaches, visual disturbances, and seizures. Patients with subfrontal meningiomas carry the highest risk of developing psychological symptoms, which makes patient-reported outcome in terms of long-term health-related quality of life (HRQOL), anxiety, and depression of particular importance. This observational study aimed to investigate long-term HRQOL, anxiety, and depression in patients with subfrontal meningiomas who underwent a bifrontal craniotomy (subfrontal) approach between 2008 and 2017 at a single tertiary center. Correlations between preoperative, perioperative, and postoperative factors and HRQOL, anxiety, and depression were analyzed to detect prognostic factors. Seventy-seven consecutive patients who underwent operations at Rigshospitalet, Copenhagen, Denmark, between 2008 and 2017 were retrospectively analyzed. Patients were prospectively invited to respond to the Functional Assessment of Cancer Therapy-General, Functional Assessment of Cancer Therapy-Brain, and Hospital Anxiety and Depression Scale. Information regarding preoperative, perioperative, and postoperative factors were collected from the patients' medical records and scans. Patients with subfrontal meningiomas exhibited better HRQOL and lower levels of anxiety and depression than general populations and other meningioma and glioblastoma cohorts. The only statistically significant prognostic factors for long-term HRQOL were number of symptoms at diagnosis and whether patients were discharged home or to a local hospital postoperatively. Tumor and peritumoral brain edema volumes were not prognostic factors. Patients with subfrontal meningiomas exhibited better long-term postoperative HRQOL and were less likely to have anxiety or depression than the reference populations. This information on long-term prognosis is very valuable for patients, next of kin, and neurosurgeons and has not been previously studied in detail.

Effects of combined aerobic-strength training and yoga on quality of life and related parameters in women with pituitary adenoma after surgery: a randomized crossover study.

The pituitary gland is responsible for hormonal balance in the body, and disruption of hormonal balance in patients with pituitary adenoma (PA) indirectly affects the quality of life. This study aimed to examine the effects of yoga and combined aerobic and strength training (A+ST) on quality of life and related parameters such as sleep, fatigue, emotional state, sexual function, and cognitive status in women with PA. Ten women with PA were included in this randomized crossover study. Group 1 (n = 5, mean age: 52 ± 13.5 years) received A+ST for the first 6 weeks, a 2-week washout period, and yoga for the second 6 weeks. Group 2 (n = 5, mean age: 41.8 ± 14 years) received the yoga program first, followed by the A+ST program. Participants were assessed using the following tools before and after each exercise intervention: Functional Assessment of Cancer Therapy-Brain (FACT-Br) (quality of life), Pittsburg Sleep Quality Index, Fatigue Severity Scale (FSS), Female Sexual Function Index (FSFI), Hospital Anxiety and Depression Scale (HADS), and Montreal Cognitive Assessment Scale (MOCA). FACT-Br scores were higher after the yoga program, HADS anxiety score was lower after the A+ST program, and MOCA scores increased after both exercise programs (P < 0.05). FSS score decreased after both exercise programs, but not significantly. In addition, nonsignificant decreases in HADS anxiety and depression scores and increased FSFI scores were observed after the yoga program. A+ST and yoga have positive effects on the quality of life in PA. We recommend yoga and A+ST as a supportive therapy for this population that may face comorbidities after surgical and medical treatment. Our results indicate these patients may benefit from physiotherapist-guided exercise programs.

Effects of low-dose naltrexone on quality of life in high-grade glioma patients: a placebo-controlled, double-blind randomized trial.

At diagnosis and throughout the disease course, patients with high-grade glioma (HGG) experience a diminished quality of life (QOL) and increased fatigue. Naltrexone, an orally semisynthetic opiate antagonist, is FDA-approved for the treatment of heroin/alcohol addiction, and low-dose naltrexone (LDN) has been observed to improve QOL and lower fatigue in other neurological illnesses, such as multiple sclerosis. LDN is believed to function as a partial agonist and can lead to shifts in neurochemicals that reduce fatigue. Based on this, we sought to study whether LDN has an impact on QOL and fatigue in patients with HGG. In a placebo-controlled, double-blind study, we randomized 110 HGG patients to receive placebo (N = 56) or LDN 4.5mg orally at night (N = 54). Subjects received LDN or placebo at day 1 of concurrent radiation and temozolomide therapy and continued for 16weeks. Change from baseline in patient-reported outcomes of QOL (Functional Assessment of Cancer Therapy-Brain) and fatigue (Functional Assessment of Chronic Illness Therapy-Fatigue) was assessed. Demographics were WHO grade IV (85%), male (56%), KPS 90-100 (51%), grossly resected (55%), and mean age of 56years. QOL and fatigue changes between baseline and post concurrent chemotherapy and radiation therapy were not significantly different between patients receiving LDN or placebo. The adverse event profiles for LDN and placebo were similar and attributed to concomitant use of temozolomide. LDN has no effect on QOL and fatigue in HGG patients during concurrent chemotherapy and radiation therapy. United States National Library of Medicine Clinical Trials.gov NCT01303835, Date 2/25/2011.

A Single-Institution Retrospective Study of Patients Treated With Laser-Interstitial Thermal Therapy for Radiation Necrosis of the Brain.

ObjectLaser-interstitial thermal therapy (LITT) has been proposed as an alternative treatment to surgery for radiation necrosis (RN) in patients treated with stereotactic radiosurgery (SRS) for brain metastases. The present study sought to retrospectively analyze LITT outcomes in patients with RN from SRS.MethodsThis was a single-institution retrospective study of 30 patients treated from 2011-2018 with pathologically-proven RN after SRS for brain metastases (n=28) or proximally treated extracranial lesions treated with external beam radiotherapy (n=2). Same-day biopsy was performed in all cases. Patients were prospectively followed with Functional Assessment of Cancer Therapy - Brain (FACT-Br), EuroQol-5 Dimension (EQ-5D), Hopkins Verbal Learning Test (HVLT) and clinical history and examination. Adjusted means, standard errors and tests comparing visits to pre-LITT were generated. Kaplan-Meier method was used to estimate time overall survival. Competing risk analysis was used to estimate cumulative incidence of LITT failure.ResultsIn our patient population, median time from radiotherapy to LITT was 13.1 months. Median SRS dose and median LITT treatment target volume were 20 Gy (IQR 18-22) and 3.5 cc (IQR 2.2-4.6), respectively. Seventy-seven percent of our patients tapered off steroids within one month. There were only two instances of RN recurrence after LITT, with recurrence defined as recurrence of symptoms after initial improvement. These recurrences occurred at 1.9 and 3.4 months. The three-, six- and nine-month freedom from recurrence rates were 95.7%, 90.9%, and 90.9%. Median survival in our patient population with pathologically confirmed RN treated with LITT was 2.1 years. Regarding the quality of life questionnaires with which some patients were followed as part of different prospective studies, completion rates were 22/30 for FACT-Br, 16/30 for the EQ-5D and 8/30 for HVLT. Quality of life questionnaire results were overall stable from baseline. Mean FACT-Br scores were stable from baseline (17.9, 16.6, 21.4 and 22.8) to three months (18.8, 15.4, 18.4 and 23.4) (p=0.38, 0.53, 0.09 and 0.59). The mean EQ-5D Aggregate score was stable from baseline (7.1) to one month (7.6) (p=0.25). Mean HVLT-R Total Recall was stable from baseline (20.6) to three months (18.4) (p=0.09). There was a statistically significant decrease in mean Karnofsky Performance Scale (KPS) score from baseline (84) to three-month follow-up (75) (p=0.03).ConclusionsLITT represents a safe and durably effective treatment option for RN in the brain. Results demonstrate a median survival of 2.1 years from LITT with only two recurrences, both within four months of treatment and salvageable. Patient-reported outcomes showed no severe declines after LITT. Quality of life questionnaires demonstrated stable well-being and functionality from baseline. LITT should be considered for definitive treatment of RN, especially in cases where patients have significant side effects from standards medical therapies such as steroids or if steroids are minimally effective.

NCOG-48. LONGITUDINAL ASSESSMENT OF SUBJECTIVE COGNITIVE FUNCTION IN A BRAIN TUMOR SAMPLE: IMPROVED CORRESPONDENCE WITH NEUROPSYCHOLOGICAL PERFORMANCE OVER TIME

Abstract INTRODUCTION Estimates of subjective cognitive function (SCF) generally show minimal correlation with objective measures of neurocognitive function (NCF). Our group recently validated a new metric of SCF in neuro-oncology patients, creating the Cognitive Index of the Functional Assessment of Cancer Therapy-Brain (FACT-Br-CI). This study examines whether brain tumor (BT) patients evaluated on more than one occasion show improved relationship between SCF and NCF. We hypothesized that change scores in SCF and NCF across evaluation would be more highly correlated than SCF and NCF at either timepoint. METHODS A retrospective study of BT patients who completed two neuropsychological evaluations (baseline, follow-up) was conducted. NCF was measured by the clinical trial battery composite (CTBC), a mean of 6 commonly used neuropsychological test scores. SCF was measured by the FACT-Br-CI. Mood/Anxiety were measured by the Beck scales (BAI/BDI-II). Change over time on each metric was evaluated with paired t-test. Correlational analyses evaluated relationships between NCF, SCF, and mood within and between time points. RESULTS Twenty-nine patients (16 female; mean age=54.6y; mean education=15.5y) completed all CTBC measures and FACT-Br-CI, 28 of whom completed and BDI and/or BAI. On group analyses, there were no significant differences between baseline and follow-up on CTBC (t=-.53;p=ns) or FACT-Br-CI (t=-.98;p=ns). Correlations between CTBC and FACT-Br-CI were nonsignificant at baseline (r=.24;p=ns), but significant at follow-up (r=.56;p=0.002). Change scores over time were unrelated (r=-.104;p=ns). Similar to previous studies, the FACT-BR-CI correlated with the BDI-II at baseline (r=-.38;p=0.04) and follow-up (r=-.59;p&amp;lt; 0.001) and with the BAI at follow-up (r=-.44;p=0.02). CONCLUSION In this small group of brain tumor patients seen for repeated neuropsychological evaluations, we found that agreement between SCF and NCF was much higher on their second than initial evaluation. These findings suggest that patients may develop enhanced awareness of their cognitive function from an initial evaluation that persists over time.

Reliability and validity of a novel cognitive self-assessment tool for patients with cancer.

Subjective cognitive function is an important outcome measure in oncology. The Functional Assessment of Cancer Therapy-Brain (FACT-Br) is a quality of life (QoL) measure that includes indices of physical, emotional, social, and neurologic aspects of disease but does not measure cognitive function. This study seeks to validate a novel index of cognition derived from the FACT-Br. Patients with heterogeneous cancer diagnoses (N = 214) completed neuropsychological evaluation and self-report measures. Nine FACT-Br items regarding cognition were combined to form the FACT-Br-cognitive index (CI). Reliability was evaluated by exploratory factor analysis and internal consistency. Concurrent validity was assessed by correlating FACT-Br-CI with the Patient-Reported Outcomes Measurement Information System (PROMIS) Cognitive-8 scales. Discriminant validity was assessed by correlating FACT-Br-CI with other FACT-Br indices and the Beck Depression and Anxiety Inventories (BDI, BAI). Exploratory analyses evaluated the impact of cognitive performance and disease variables on FACT-Br-CI. The FACT-Br-CI consisted of a single factor that demonstrated high internal consistency (α = 0.867) and strong concurrent validity, correlating strongly with PROMIS Cognitive-8 scales (r = 0.675-0.782). The relationship between the FACT-Br-CI and other FACT subscales ranged from moderate to strong (r = 0.372-0.601), as did correlations with measures of depression (BDI, r = -0.621) and anxiety (BAI, r = -0.450). Modest correlations were observed with neuropsychological measures (rs = 0.249-0.300). The FACT-Br-CI is a reliable and valid measure of self-reported cognition. Studies that included the FACT-Br could be retrospectively analyzed to assess subjective cognitive outcomes, enriching the information from prior research. Integration of the FACT-Br-CI in routine clinical care may be an efficient method of monitoring cognition.

Quality of Life Is Independently Associated With Neurocognitive Function in Patients With Brain Tumors: Analysis of a Prospective Clinical Trial

We conducted the first prospective longitudinal study examining the independent association between patient-reported health-related quality of life (hrQoL) (physical, social/family, emotional, functional, and brain cancer-specific) and neurocognitive function (NCF), while controlling for mood symptoms in patients with primary brain tumors. Patients with primary brain tumors (n=59) receiving brain radiation therapy underwent hrQOL (Functional Assessment of Cancer Therapy-Brain), mood (Beck Depression and Anxiety Inventories), and neurocognitive evaluation at baseline and 3, 6, and 12 months postradiation therapy in a prospective clinical trial. Neurocognitive assessments measured attention/processing speed, memory, and executive function, including the Delis-Kaplan Executive Function System Verbal Fluency, Hopkins Verbal Learning Test Revised (HVLT-R), and Brief Visuospatial Memory Test. Subjects underwent neurocognitive, mood, and hrQoL assessments in the same testing session. Multivariable linear mixed-effects models assessed associations between hrQOL and NCF over time, controlling for patient, tumor, and treatment characteristics as well as timepoint-specific patient-reported mood (ie, anxiety and depression symptoms). P values were adjusted for multiple comparisons. Higher physical hrQoL was associated with better verbal memory (HVLT-R Total Recall, P=.047), and higher functional hrQoL was associated with better executive function (Delis-Kaplan Executive Function System Verbal Fluency Switching Total, P=.009) and verbal memory (HVLT-R Delayed Recall, P=.006). Higher brain tumor-specific hrQoL was associated with better verbal and nonverbal memory (HVLT-R Total, P=.004 and Delayed Recall, P=.030; Brief Visuospatial Memory Test Total, P=.049 and Delayed Recall, P=.049). There was no association between social/family or emotional hrQoL and NCF after controlling for mood. Higher physical, functional, and brain tumor-specific hrQoL were associated with better executive function and memory among patients with primary brain tumors. Physical and functional impairments are correlated with cognitive performance. Interventions to maximize quality of life after treatment may influence neurocognition and vice versa.

A phase III multicenter randomized controlled trial of postsurgical stereotactic radiotherapy versus surgically targeted radiation therapy (STaRT) for the treatment of large (&gt;2.5cm) newly diagnosed brain metastases: Trial in progress.

TPS2067 Background: Resection (R) followed by single or multi-fraction stereotactic radiosurgery (SRT) of brain metastases lowers resection bed recurrence compared to R alone. Nevertheless, for larger (&gt;2.5cm) brain metastasis, 12-month recurrence rates after R+SRT can exceed 20–30%. Aiming to improve outcomes, a permanently implanted collagen tile brachytherapy device (GammaTile or GT, GT Medical Technologies, Tempe, AZ) utilizing Cs-131 seeds embedded within a bioresorbable collagen tile was developed and is described as Surgically Targeted Radiation Therapy (STaRT) to distinguish it from external beam radiation therapy. It is hypothesized that immediate adjuvant radiotherapy (RT) and/or RT dose intensification could improve outcomes. The device is FDA-cleared for this indication and early commercial use is demonstrating favorable safety and efficacy outcomes. STaRT allows rapid dose delivery of radiation therapy directly to the tumor bed with predictable dosimetry immediately at the time of resection, and an intense but localized radiation treatment, which may confer a reduced risk for radiation necrosis compared to other therapies. The device is easily placed with minimal additional operative time and limited staff radiation exposure. It is hypothesized that R+ STaRT will increase the surgical bed recurrence-free survival, while reducing the impact on functional and neurocognitive status compared to R+SRT. Methods: Multicenter, randomized, comparison trial of patients with resectable, previously untreated “index” brain metastases measuring ≥2.5–5 cm, and 0–3 other tumors, will be preoperatively randomized 1:1 to undergo either R+ SRT or R+STaRT to the index lesion; unresected tumors in both groups will receive SRT. Planned sample size is 180 from 13 sites. Enrollment will open in Q1. Primary endpoint is surgical bed-recurrence free survival. Secondary endpoints include overall survival, quality of life (Functional Assessment of Cancer Therapy-Brain, Linear Analog Self-Assessment), neurocognition (Hopkins Verbal Learning Test, Trail Making Tests, Controlled Oral Word Association), functional status (Karnofsky Performance Scale, Barthel-ADL), and adverse events. Follow-up will be at 1,3,6,9, and 12 months, then every 6 months through 24 months. This will be the first randomized trial comparing R+SRT versus R+STaRT delivered by Cs-131 sources in permanently implanted resorbable collagen tile carriers. Primary and secondary outcome measures will be captured to elucidate the potential risks and benefits of these two differing post-operative RT delivery methods in the setting of newly diagnosed metastatic brain tumors. Clinical trial information: NCT04365374.

NCOG-70. RELIABILITY AND VALIDITY OF A NEW SELF-REPORT INDEX OF COGNITIVE CONCERNS IN BRAIN TUMOR PATIENTS

Abstract INTRODUCTION Subjective cognitive dysfunction is an important outcome measure in neuro-oncology and may provide additional information beyond performance-based neuropsychological testing. The Functional Assessment of Cancer Therapy-Brain (FACT-Br) is a frequently used quality of life (QoL) measure that includes indices of physical, emotional, social, and neurologic aspects of disease, but does not measure cognitive concerns. This study seeks to develop and validate an index of self-reported cognition derived from existing items on the FACT-Br. METHODS 145 patients (Mage=51.08, Medu=15.63) with heterogeneous brain tumor diagnoses completed neuropsychological evaluation including cognitive testing and self-report measures. Nine FACT-Br items regarding cognition were combined to form the Cognitive Index (CI). Reliability of the CI was measured with Cronbach’s alpha. Concurrent validity was assessed by correlating the CI with the Patient-Reported Outcomes Measurement Information System (PROMIS) Cognitive Abilities-8 or PROMIS Cognitive Concerns-8. Discriminant validity was assessed by correlation of the CI with other FACT-Br indices and the Beck Depression and Anxiety Inventories (BDI, BAI). RESULTS Internal consistency within the CI was high (Cronbach’s a 0.864). The CI correlated strongly with the PROMIS-Abilities (r =.680; p&amp;lt; 0.001) and PROMIS-Concerns (r=.780; p&amp;lt; 0.001) indicating high convergent validity. Moderate correlations were observed between the CI and the physical and functional subscales of the FACT (r=.453 and .555), whereas correlations with the social and emotional functioning subscales were weaker (r=.381 and .325). The FACT-Br-CI correlated strongly with BDI (r=-.622) and more weakly with the BAI (r=-.344). Consistent with prior literature, the CI showed modest correlations with neuropsychological measures, including verbal memory encoding (r=.300), verbal fluency (r=.252) and a composite measure of cognition (r=.249; all p’s&amp;lt; .01). CONCLUSIONS The FACT-Br-CI is a reliable and valid measure of self-reported cognition. Studies that include the FACT-Br could be retrospectively analyzed to assess self-reported cognitive outcomes, enriching the information gained from prior research.

Longitudinal Analysis Of Quality Of Life As An Independent Predictor Of Neurocognitive Function In Brain Tumor Patients

Primary brain tumor patients experience reduced health-related quality of life (hrQoL), which may be compounded by treatments including radiation therapy (RT). We conducted a prospective longitudinal study to examine the association between hrQoL (physical, social/family, emotional, functional, and brain cancer-specific) and domain-specific neurocognitive function in primary brain tumor patients. Primary brain tumor patients (n = 59) receiving fractionated brain RT underwent comprehensive hrQOL (Functional Assessment of Cancer Therapy-Brain [FACT-Br]) and neurocognitive evaluation at baseline and 3, 6, and 12 months post-RT. Neurocognitive assessments measured attention and processing speed (Delis-Kaplan Executive Function System Trail Making Test [DKEFS-TMT] Visual Scanning, Number Sequencing, and Letter Sequencing and Weschler-Adult Intelligence Scale-IV [WAIS-IV] Digit Span and Coding), memory (Hopkins Verbal Learning Test-Revised [HVLT-R] Total and Delayed Recall and Brief Visuospatial Memory Test [BVMT] Total and Delayed Recall), and executive function (DKEFS Verbal Fluency [DKEFS-VF] Letter Fluency and Category Switching and Wisconsin Card Sorting Test [WCST] Perseverative Errors). Cognitive scores were transformed to t-scores controlling for age and sex; higher cognitive t-scores and hrQOL scores reflect better function. Multivariable linear mixed-effects models assessed independent association between hrQOL scores and neurocognitive function over time, controlling for patient, tumor, and treatment characteristics as well as timepoint-specific patient-reported anxiety and depression symptoms. P-values were corrected for multiple comparisons using false discovery rate. Median age of the cohort was 47 years. Most were male (61%) and married (71%). Higher physical hrQoL showed significant independent association with better verbal memory (HVLT Total Recall p = 0.047), while higher functional hrQoL correlated with better executive function (DKEFS-VF Switching Total p = 0.009) and verbal memory (HVLT Delayed Recall p = 0.006). Higher brain cancer-specific hrQoL was associated with better performance on tests of verbal and non-verbal memory (HVLT Total p = 0.004 and Delayed Recall p = 0.030; BVMT Total p = 0.049 and Delayed Recall p = 0.049). There was no significant association between social/family or emotional hrQoL and neurocognitive scores. This is the first prospective study to assess the independent association of hrQOL and neurocognition in primary brain tumor patients. We found that reduced physical, functional, and brain cancer-specific hrQoL were independently associated with worse executive function and memory among primary brain tumor patients receiving RT. Physical and functional impairments may impact cognitive performance in this population after RT.

Health-related quality of life after Gamma Knife radiosurgery in patients with 1\u201310 brain metastases

PurposeIncreasingly more patients with multiple (> 4) brain metastases (BM) are being treated with stereotactic radiosurgery (SRS). Preserving patients’ health-related quality of life (HRQoL) is an important treatment goal. The aim of this study was to assess (individual) changes in HRQoL in patients with 1–10 BM over time.MethodsA total of 92 patients were assessed before (n = 92) and at 3 (n = 66), 6 (n = 53), and 9 (n = 41) months after Gamma Knife radiosurgery (GKRS), using the Functional Assessment of Cancer Therapy-Brain (FACT-Br). The course of HRQoL was analyzed using linear mixed models. Clinical minimally important differences were used to evaluate individual changes.ResultsAt group level, patients’ physical well-being worsened, whereas emotional well-being improved over 9 months. Scores on other HRQoL subscales did not change significantly. Number (1–3 versus 4–10) and volume (small, medium, and large) of BM did not influence HRQoL over time, except for the subscale additional concerns; medium intracranial tumor volume was associated with less additional concerns. On the individual level as well, physical well-being declined while emotional well-being improved in most patients over 9 months after GKRS. At patient level, however, most patients had both declines as well as improvements in the different HRQoL aspects.ConclusionOur results indicate that even in patients with up to 10 BM, both at group and individual subscale level, aspects of HRQoL remained stable over nine months after GKRS, except for an improvement in emotional well-being and a decline in physical well-being. Nevertheless, HRQoL scores varied considerably at the individual patient level.Trail registration numberClinicalTrials.gov Identifier: NCT02953756, November 3, 2016.

Laser Ablation of Abnormal Neurological Tissue Using Robotic NeuroBlate System (LAANTERN): 12-Month Outcomes and Quality of Life After Brain Tumor Ablation.

BACKGROUNDLaser Ablation of Abnormal Neurological Tissue using Robotic NeuroBlate System (LAANTERN) is an ongoing multicenter prospective NeuroBlate (Monteris Medical) LITT (laser interstitial thermal therapy) registry collecting real-world outcomes and quality-of-life (QoL) data.OBJECTIVETo compare 12-mo outcomes from all subjects undergoing LITT for intracranial tumors/neoplasms.METHODSDemographics, intraprocedural data, adverse events, QoL, hospitalizations, health economics, and survival data are collected; standard data management and monitoring occur.RESULTSA total of 14 centers enrolled 223 subjects; the median follow-up was 223 d. There were 119 (53.4%) females and 104 (46.6%) males. The median age was 54.3 yr (range 3-86) and 72.6% had at least 1 baseline comorbidity. The median baseline Karnofsky Performance Score (KPS) was 90. Of the ablated tumors, 131 were primary and 92 were metastatic. Most patients with primary tumors had high-grade gliomas (80.9%). Patients with metastatic cancer had recurrence (50.6%) or radiation necrosis (40%). The median postprocedure hospital stay was 33.4 h (12.7-733.4). The 1-yr estimated survival rate was 73%, and this was not impacted by disease etiology. Patient-reported QoL as assessed by the Functional Assessment of Cancer Therapy-Brain was stabilized postprocedure. KPS declined by an average of 5.7 to 10.5 points postprocedure; however, 50.5% had stabilized/improved KPS at 6 mo. There were no significant differences in KPS or QoL between patients with metastatic vs primary tumors.CONCLUSIONResults from the ongoing LAANTERN registry demonstrate that LITT stabilizes and improves QoL from baseline levels in a malignant brain tumor patient population with high rates of comorbidities. Overall survival was better than anticipated for a real-world registry and comparative to published literature.

55. A RANDOMIZED, MULTICENTER PHASE III TRIAL OF SURGERY PLUS STEREOTACTIC RADIOSURGERY (SRS) COMPARED WITH SURGERY PLUS PERMANENTLY IMPLANTED COLLAGEN TILE BRACHYTHERAPY (CTBT) FOR RESECTABLE METASTATIC BRAIN TUMORS-PROTOCOL IN PROGRESS

BACKGROUNDResection (R) followed by single or multi-fraction stereotactic radiosurgery (SRS) lowers resection bed recurrence compared to R alone. Nevertheless for larger brain metastasis (>2.5 cm) 12-month recurrence rates after R+SRS can exceed 20–30%. Aiming to improve outcomes, a permanently implanted collagen tile brachytherapy (CTBT) device (GammaTile, GT Medical Technologies, Tempe AZ) utilizing Cs-131 was developed, hypothesizing that immediate adjuvant radiotherapy (RT) and/or RT dose intensification could improve outcomes. The device received FDA clearance for this indication, based on a single-arm pre-commercial study and in early commercial use due to the excellent safety and local control of R+CTBT. It is hypothesized that R+CTBT will increase the time to post-resection-recurrence, while prolonging survival and reducing the impact on functional and neurocognitive status compared to R+SRS.STUDY DESIGNMulticenter, randomized, comparison trial. Patients with resectable, previously untreated “index” brain metastases measuring >2.5–5 cm and 0–3 other tumors will be preoperatively randomized 1:1 to undergo either R+ SRS or R+CTBT to the index lesion; unresected tumors in both groups will receive SRS. Planned sample size is 160 from ~5 sites; accrual to start in Q3-2020. Primary endpoint is surgical bed-recurrence free survival. Secondary endpoints include overall survival, quality of life (Functional Assessment of Cancer Therapy-Brain, Linear Analog Self-Assessment), neurocognition (Hopkins Verbal Learning Test, Trail Making Tests, Mini-Mental Status Exam, Controlled Oral Word Association), functional decline (Karnofsky Performance Scale, Barthel-ADL), and adverse events. Follow-up will be at 1,3,6,9, and 12 months, then q 6 months through 5 years.CONCLUSIONSThis will be the first randomized trial comparing R+SRS versus R+CTBT delivered by Cs-131 sources in permanently implanted resorbable collagen tile carriers. Primary and secondary outcome measures will be captured to elucidate the potential risks and benefits of these two differing approaches for patients with metastatic brain tumors.

Development and validation of the disease-specific QOL-CD quality of life questionnaire for patients with Cushing's disease.

Cushing's disease (CD) patients experience a range of debilitating symptoms that impair quality of life (QOL) as assessed using generic measures. These generic measures are inadequate to capture the disease-specific burden of illness. The development of the CD-specific QOL-CD measure of QOL using items generated by CD patients and healthcare professionals will provide a holistic assessment of patient outcomes and efficacy of novel therapies. A total of 96 CD patients participated. A list of 177 items (version 1.0) was generated by treated CD patients (n = 9), caregivers (n = 2), healthcare providers (n = 7), and results of a MEDLINE search. Item reduction was performed through content analysis and dual scaling. Patients' rating of importance was incorporated to reduce to a final version of 56 items (version 3.0). Evidence for test-retest reliability was sought through administering the QOL-CD 1 week apart and Cronbach's α of each subscale. Construct validity was assessed through extreme group analysis and comparison with the normal Canadian population. Concurrent validity was sought through comparison with the SF-36, Functional Assessment of Cancer Therapy-Brain (FACT-Br), and Karnofsky Performance Status (KPS). Perioperative testing was conducted on CD patients (n = 25) against nonfunctioning pituitary adenoma controls (n = 25) through pre- and postoperative testing. A total of 96 CD patients (86 females and 10 males; mean age 45.23 ± 14.16 years) participated. The QOL-CD was feasible (mean completion time 15 minutes, with 70% believing accurate capture of QOL), reliable (CD 1 week apart: r = 0.86; control 1 week apart: r = 0.83; Cronbach's α: general health = 0.73, emotional health = 0.85, physical health = 0.78, mental status = 0.82, social well-being = 0.63, medical treatment = 0.54), and valid (extreme group testing p < 0.001; SF-36 and QOL-CD general health: r = 0.56, social well-being: r = 0.21, emotional health: r = 0.61, total score: r = 0.58; FACT-Br and QOL-CD physical health: r = 0.47, social well-being: r = 0.21, emotional health: r = 0.34, total score: r = 0.68; KPS and QOL-CD general health: r = 0.32, total score: r = 0.14). Perioperative testing of CD patients (n = 25) demonstrated improvement in all subscales postoperatively, with a significant difference in emotional health (p < 0.001) and physical health (p < 0.001). The QOL-CD questionnaire has been developed for patients with CD and has demonstrated evidence for validity and reliability.

Financial toxicities in patients receiving systemic therapy for brain tumors: A cross-sectional study

Background: Apart from disease management and the toxicities of systemic therapy, financial burden is an additional liability in patients with brain tumors receiving systemic therapy. However, currently, there is a paucity of data on the financial toxicities incurred by these patients. Objectives: In this study, we aimed to assess the perceived financial toxicity and the quality of life (QOL) of patients with brain tumors receiving systemic therapy and to evaluate the factors affecting it. Materials and Methods: This single-center, cross-sectional study was conducted in the Department of Medical Oncology at the Tata Memorial Hospital in Mumbai, India, between January 2019 and March 2019. The financial toxicity scores (FTSs) were captured at a single visit from the patients with primary brain tumors with or without recurrence who visited the Neuro Medical Oncology Outpatient Department. The Comprehensive Score for Financial Toxicity-Functional Assessment of Chronic Illness Therapy and Functional Assessment of Cancer Therapy-Brain (FACT-Br) questionnaires were used to collect data on the FTS and QOL, respectively. Pearson correlation coefficient was used to determine the correlation between FTS and the various domains of QOL. Multiple linear regression was used to determine the factors that influence FTS, and P Results: A total of 147 patients were included in the study; the median age of the cohort was 38 years (range, 16–67). Of them, 102 (67.5%) were men and 48 (32.5%) were women. The median monthly income was ₹7000 ($92.75). The median FTS was 13 (interquartile range [IQR], 6–21). The associated risk factors for financial toxicity were age (beta = 0.242,P = 0.001), category under which the patient availed treatment – private (regular cost) or general (discounted cost) (beta = 0.398, P Conclusions: Financial distress was found to be severe in patients with brain tumors receiving systemic therapy. The age, payment category under which the patients availed treatment, and the disease status were found to be contributory factors. These, along with the QOL, were significantly associated with FTS.
