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

Standardizing Care of Neuro-oncology Patients Using a Customized Electronic Medical Record Toolkit

Objective

To develop and implement a customized toolkit within the electronic medical record (EMR) to standardize care of patients with brain tumors.

Patients and Methods

We built a customized structured clinical documentation support toolkit to capture standardized data at office visits. We detail the process by which this toolkit was conceptualized and developed. Toolkit development was a physician-led process to determine a work flow and necessary elements to support best practices as defined by the neuro-oncology clinical team.

Results

We have developed in our EMR system a customized work flow for clinical encounters with neuro-oncology patients. In addition to providing a road map for clinical care by our neuro-oncology team, the toolkit is designed to maximize discrete data capture. Several hundred fields of discrete data are captured through the toolkit in the context of our routine office visits. We describe the characteristics of patients seen at our clinic, the adoption of the toolkit, current initiatives supported by the toolkit, and future applications.

Conclusion

The EMR can be effectively structured to standardize office visits and improve discrete data capture. This toolkit can be leveraged to support quality improvement and practice-based research initiatives at the point of care in a neuro-oncology practice.

Functional Outcomes and Health-Related Quality of Life Following Glioma Surgery

Functional outcome following glioma surgery is defined as how the patient functions or feels. Functional outcome is a coprimary end point of surgery in patients with diffuse glioma, together with oncological outcome. In this review, we structure the functional outcome measurements following glioma surgery as reported in the last 5 yr. We review various perspectives on functional outcome of glioma surgery with available measures, and offer suggestions for their use. From the recent neurosurgical literature, 160 publications were retrieved fulfilling the selection criteria. In these publications, neurological outcomes were reported most often, followed by activities of daily living, seizure outcomes, neurocognitive outcomes, and health-related quality of life or well-being. In more than a quarter of these publications functional outcome was not reported. A minimum essential consensus set of functional outcome measurements would benefit comparison across neurosurgical reports. The consensus set should be based on a combination of clinician- and patient-reported outcomes, assessed at a predefined time before and after surgery. The selected measurements should have psychometric properties supporting the intended use including validity-related evidence, reliability, and sensitivity to detect meaningful change with minimal burden to ensure compliance. We circulate a short survey as a start towards reporting guidelines. Many questions remain to better understand, report, and improve functional outcome following glioma surgery.

Physical activity and exercise in adults diagnosed with primary brain cancer: a systematic review

PURPOSE

The aims of this systematic review were to: (1) describe physical activity (PA) levels following diagnosis of primary brain cancer, (2) determine the relationship between PA levels and health outcomes, and (3) assess the effect of participating in an exercise intervention on health outcomes following a diagnosis of brain cancer.

METHODS

PubMed, EMBASE, Scopus and CINAHL were searched for relevant articles published prior to May 1, 2020. Studies reporting levels of PA, the relationship between PA and health outcomes, and exercise interventions conducted in adults with brain cancer were eligible. The search strategy included terms relating to primary brain cancer, physical activity, and exercise. Two independent reviewers assessed articles for eligibility and methodological quality (according to Joanna Briggs Institute Critical Appraisal Tools). Descriptive statistics were used to present relevant data and outcomes.

RESULTS

15 studies were eligible for inclusion. Most adults with brain cancer were insufficiently active from diagnosis through to post-treatment. Higher levels of PA were associated with lower severity of brain cancer specific concerns and higher quality of life. Preliminary evidence suggests that exercise is safe, feasible and potentially beneficial to brain cancer symptom severity and interference, aerobic capacity, body composition and PA levels. However, the level of evidence to support these findings is graded as weak.

CONCLUSIONS

Evidence suggests that it is likely appropriate to promote those with brain cancer to be as physically active as possible. The need or ability of those with brain cancer to meet current PA guidelines promoted to all people with cancer remains unclear.

A phase II study of dose-dense temozolomide and lapatinib for recurrent low-grade and anaplastic supratentorial, infratentorial, and spinal cord ependymoma

BACKGROUND

No standard medical treatment exists for adult patients with recurrent ependymoma, and prospective clinical trials in this population have not succeeded because of its rarity and challenges in accruing patients. The Collaborative Ependymoma Research Network conducted a prospective phase II clinical trial of dose-dense temozolomide (TMZ) and lapatinib, targeting the unmethylated O6-methylguanine-DNA methyltransferase (MGMT) promoter status and increased expression of ErbB2 (human epidermal growth factor receptor 2) and ErbB1 (epidermal growth factor receptor) in ependymomas.

METHODS

Patients age 18 or older with histologically proven and progressive ependymoma or anaplastic ependymoma were eligible and received dose-dense TMZ and daily lapatinib. The primary outcome measure was median progression-free survival (PFS). Landmark 6- and 12-month PFS and objective response were measured. Serial assessments of symptom burden using the MD Anderson Symptom Inventory Brain Tumor (MDASI-BT)/MDASI-Spine Tumor modules were collected.

RESULTS

The 50 patients enrolled had a median age of 43.5 years, median Karnofsky performance status of 90, and a median of 2 prior relapses. Twenty patients had grade III, 16 grade II, and 8 grade I ependymoma. Half had spinal cord tumors; 15 had a supratentorial tumor, 8 infratentorial, and 2 had disseminated disease. Treatment was well tolerated. The median PFS was 7.8 months (95% CI: 5.5,12.2); the 6- and 12-month PFS rates were 55% and 38%, with 2 complete and 6 partial responses. Measures of symptom burden showed reduction in moderate-severe pain and other disease-related symptoms in most patients.

CONCLUSIONS

This treatment, with demonstrated clinical activity with objective responses and prolonged disease control associated with disease-related symptom improvements, is an option as a salvage regimen for adult patients with recurrent ependymoma.

A Bayesian adaptive randomized phase II multicenter trial of bevacizumab with or without vorinostat in adults with recurrent glioblastoma

BACKGROUND

Bevacizumab has promising activity against recurrent glioblastoma (GBM). However, acquired resistance to this agent results in tumor recurrence. We hypothesized that vorinostat, a histone deacetylase (HDAC) inhibitor with anti-angiogenic effects, would prevent acquired resistance to bevacizumab.

METHODS

This multicenter phase II trial used a Bayesian adaptive design to randomize patients with recurrent GBM to bevacizumab alone or bevacizumab plus vorinostat with the primary endpoint of progression-free survival (PFS) and secondary endpoints of overall survival (OS) and clinical outcomes assessment (MD Anderson Symptom Inventory Brain Tumor module [MDASI-BT]). Eligible patients were adults (≥18 y) with histologically confirmed GBM recurrent after prior radiation therapy, with adequate organ function, KPS ≥60, and no prior bevacizumab or HDAC inhibitors.

RESULTS

Ninety patients (bevacizumab + vorinostat: 49, bevacizumab: 41) were enrolled, of whom 74 were evaluable for PFS (bevacizumab + vorinostat: 44, bevacizumab: 30). Median PFS (3.7 vs 3.9 mo, P = 0.94, hazard ratio [HR] 0.63 [95% CI: 0.38, 1.06, P = 0.08]), median OS (7.8 vs 9.3 mo, P = 0.64, HR 0.93 [95% CI: 0.5, 1.6, P = 0.79]) and clinical benefit were similar between the 2 arms. Toxicity (grade ≥3) in 85 evaluable patients included hypertension (n = 37), neurological changes (n = 2), anorexia (n = 2), infections (n = 9), wound dehiscence (n = 2), deep vein thrombosis/pulmonary embolism (n = 2), and colonic perforation (n = 1).

CONCLUSIONS

Bevacizumab combined with vorinostat did not yield improvement in PFS or OS or clinical benefit compared with bevacizumab alone or a clinical benefit in adults with recurrent GBM. This trial is the first to test a Bayesian adaptive design with adaptive randomization and Bayesian continuous monitoring in patients with primary brain tumor and demonstrates the feasibility of using complex Bayesian adaptive design in a multicenter setting.

Living with a central nervous system (CNS) tumor: findings on long-term survivorship from the NIH Natural History Study

Background

Primary central nervous system (CNS) tumors are often associated with high symptom burden and a poor prognosis from the time of diagnosis. The purpose of this study is to describe patient-reported outcomes (PRO) data from long-term survivors (LTS; ≥5-year survival post-diagnosis).

Methods

Clinical/treatment/molecular characteristics and PROs (symptom burden/interference (MDASI-BT/SP), perceived cognition (Neuro-QoL), anxiety/depression (PROMIS), and general health status (EQ-5D-3L)) were collected on 248 adult LTS between 9/2016 and 8/2019. Descriptive statistics and regression analysis were used to report results.

Results

Participants had a median age of 47 years (19-82) and were primarily White (83%) males (51%) with high-grade tumors (59%) and few mutations. Forty-two percent of the 222 brain tumor LTS reported no moderate-to-severe symptoms, whereas 45% reported three or more; most common symptoms were fatigue (40%), difficulty remembering (29%), and drowsiness (28%). Among spine tumor LTS (n = 42), nearly half reported moderate-to-severe weakness, pain, fatigue, and numbness/tingling, with 72% experiencing activity-related interference. Severe anxiety, depression, and cognitive symptoms were reported in up to 23% of the sample. Brain tumor LTS at higher risk for severe symptoms were more likely to be young, unemployed, and have poor KPS (Karnofsky Performance Status), whereas high symptom-risk spinal cord tumor LTS had poor KPS and received any tumor treatment.

Conclusions

Findings indicate LTS fall into distinct cohorts with no significant symptoms or very high symptom burden, regardless of tumor grade or mutational profile. These LTS data demonstrate the need for survivorship care programs and future studies to explore the symptom trajectory of all CNS tumor patients for prevention and early interventions.

Predicting postoperative quality-of-life outcomes in patients with metastatic spine disease: who benefits?

Symptomatic spinal metastasis occurs in around 10% of all cancer patients, 5%-10% of whom will require operative management. While postoperative survival has been extensively evaluated, postoperative health-related quality-of-life (HRQOL) outcomes have remained relatively understudied. Available tools that measure HRQOL are heterogeneous and may emphasize different aspects of HRQOL. The authors of this paper recommend the use of the EQ-5D and Spine Oncology Study Group Outcomes Questionnaire (SOSGOQ), given their extensive validation, to capture the QOL effects of systemic disease and spine metastases. Recent studies have identified preoperative QOL, baseline functional status, and neurological function as potential predictors of postoperative QOL outcomes, but heterogeneity across studies limits the ability to derive meaningful conclusions from the data. Future development of a valid and reliable prognostic model will likely require the application of a standardized protocol in the context of a multicenter study design.

Measuring Self-Reported Cancer-Related Cognitive Impairment: Recommendations From the Cancer Neuroscience Initiative Working Group

Cancer and its treatments are associated with increased risk for cancer-related cognitive impairment (CRCI). Methods and measures used to study and assess self-reported CRCI (sr-CRCI), however, remain diverse, resulting in heterogeneity across studies. The Patient-Reported Outcomes Working Group has been formed to promote homogeneity in the methods used to study sr-CRCI. In this report, using a psychometric taxonomy, we inventory and appraise instruments used in research to measure sr-CRCI, and we consider advances in patient-reported outcome methodology. Given its psychometric properties, we recommend the Patient-Reported Outcome Measurement Information System Cognitive Function Short Form 8a for measurement of sr-CRCI in cancer patients and survivors, at a minimum, to increase scientific rigor and progress in addressing CRCI.

Evaluating the psychometric properties of the Immunotherapy module of the MD Anderson Symptom Inventory

INTRODUCTION

Immunotherapies have revolutionized the treatment of various cancers, but little is known about their symptomatic toxicity. Assessing these symptoms is best accomplished by asking the patients themselves. However, such reports are subjective and may face challenges as bonafide scientific data. Demonstrating the validity of symptom assessment tools, mainly through the reduction of measurement errors, has the potential to improve patient care if these tools are widely adopted. To that end, we present herein the psychometric properties of the Immunotherapy for Early-Phase Trials module of the MD Anderson Symptom Inventory (MDASI-Immunotherapy EPT) in patients receiving various immunotherapies in early phase trials at a major cancer center.

METHODS

One hundred forty-five patients completed the inventory at baseline, with 85 of them also doing so after 9 weeks of treatment. The mean (±SD) age of the patients was 57.0±12.9 years. Also, 56% of the patients were women, 79% identified as white, and 49% had at least some college education.

RESULTS

The internal consistency reliability of the MDASI-Immunotherapy EPT was excellent, as the Cronbach's alphas for all of its subscales were at least 0.88 (range 0.88-0.95). Known-group validity based on Eastern Cooperative Oncology Group performance status groupings was excellent at 9 weeks after the start of an immunotherapy trial for the MDASI-Immunotherapy EPT severity (effect size, 0.96) and interference (effect size, 0.82) subscales. We found substantial changes in the symptom items difficulty remembering (effect size, -0.85), fever and/or chills (effect size, -0.63), disturbed sleep (effect size, -0.52), diarrhea (effect size, -0.42), and swelling of hands, legs, or feet (effect size, -0.39).

CONCLUSIONS

In conclusion, the MDASI-Immunotherapy EPT is a valid, reliable, and sensitive tool for measuring symptomatic toxicity.

Psychometric validity and reliability of the Danish version of the MD Anderson Symptom Inventory Brain Tumor Module

Background

The complexity of disease- and treatment-related symptoms causes profound distress and deterioration of health-related quality of life among patients with brain tumors. Currently, there is no Danish validated disease-specific instrument that focuses solely on measures of both neurologic and cancer-related symptoms of patients with brain tumors. The MD Anderson Symptom Inventory Brain Tumor Module (MDASI-BT) is a validated patient self-report questionnaire that measures symptom prevalence, intensity, and interference with daily life. The aim of the present study was to determine the psychometric validity of the Danish translation of the MDASI-BT, and to test its utility in 3 cohorts of Danish patients across the spectrum of the brain cancer disease and treatment trajectory.

Methods

A linguistic validation process was conducted. Danish patients with malignant primary brain tumors were included to establish the psychometric validity and reliability of the Danish MDASI-BT. Cognitive debriefing interviews were conducted to support the psychometric properties.

Results

A total of 120 patients participated in this study. Coefficient αs for the symptom and interference subscales indicate a high level of reliability across all items. Corresponding symptom and interference or functional items and subscales in the MDASI-BT and European Organisation for Research and Treatment of Cancer Brain Tumor Module BN20 were significantly correlated. Cognitive debriefing provided evidence for content validity and questionnaire utility as participants were comfortable answering the questions and had no problem with the understandability or number of questions asked.

Conclusion

The MDASI-BT is a simple, concise symptom assessment tool useful for assessing the symptom severity and interference of Danish-speaking patients with brain cancer.

Effectiveness and tolerability of lacosamide as add-on therapy in patients with brain tumor-related epilepsy: Results from a prospective, noninterventional study in European clinical practice (VIBES)

Objective

To evaluate the effectiveness and tolerability of lacosamide added to one or two antiepileptic drugs (AEDs) in the treatment of patients with brain tumor–related epilepsy (BTRE), and to evaluate patients’ global impression of change and quality of life (QoL).

Methods

This was a prospective, multicenter, single‐arm, noninterventional study with a 6‐month observation period (EP0045; NCT02276053). Eligible patients (≥16 years old) had active BTRE secondary to low‐grade glioma (World Health Organization grade 1 and 2) and were receiving treatment with one or two AEDs at baseline. Lacosamide was initiated by the treating physician in the course of routine clinical practice. Primary outcomes were 50% responders (≥50% reduction in focal seizure frequency from baseline) and Patient's Global Impression of Change (PGIC) at month 6. Secondary outcomes included seizure‐free status and Clinical Global Impression of Change (CGIC) at month 6, change in QoL (5‐Level EuroQol‐5 Dimension Quality of Life Assessment) and symptom outcomes (MD Anderson Symptom Inventory–Brain Tumor) from baseline to month 6, and Kaplan‐Meier estimated 6‐month retention on lacosamide. Safety variables included adverse drug reactions (ADRs).

Results

Patients were recruited from 24 sites in Europe. Ninety‐three patients received lacosamide (mean [standard deviation] age = 44.5 [14.7] years; 50 [53.8%] male; median baseline focal seizure frequency = five seizures/28 days [range = 1‐280]), of whom 79 (84.9%) completed the study. At 6 months, 66 of 86 (76.7%) patients were 50% responders and 30 of 86 (34.9%) were seizure‐free. Improvements on PGIC were reported by 49 of 76 (64.5%) patients. Based on CGIC, 52 of 81 (64.2%) patients improved. QoL and symptoms outcome measures remained stable. Kaplan‐Meier estimated 6‐month retention rate was 86.0% (N = 93). Fifteen (16.1%) patients reported ADRs; four (4.3%) had ADRs leading to discontinuation (N = 93).

Significance

Results of this prospective, noninterventional study suggest that add‐on lacosamide is effective and generally well tolerated in patients with BTRE.

Towards the targeted assessment of relevant problems: Optimization of the distress Thermometer for adult neuro-oncological patients

OBJECTIVE

Generic psychosocial screening tools may not reflect the unique symptom profile of brain tumour patients (BTPs). The aim was to adapt the problem list of the distress thermometer (DT) for BTPs.

METHODS

First, items of low relevance for BTPs were identified on basis of retrospective analyses. Second, relevant yet missing problems were identified via an extensive literature search, qualitative interviews with BTPs and experts, as well as an online expert survey. The resulting raw version of the adapted problem list in BTPs was subsequently pretested.

RESULTS

In the first part, data of n = 657 BTPs were analysed. Twelve items (20%) were excluded in this step as they proved to be less relevant for BTPs (i.e., items were endorsed by less than 10% and without significant correlations to patients' DT score). In the second part, qualitative interviews and the online survey with 102 professionals led to the addition of 21 new and the modification and condensation of 17 relevant problems specific for BTPs. This adapted list was than successfully pretested in n = 19 patients, leading to the 'distress thermometer brain tumour problem list' (DT-BT), consisting of 42 relevant problems.

CONCLUSION

The adapted problem list for the DT particularly reflects the neurological and psychosocial burden of an intracranial tumour and allows for the targeted assessment of the specific burdens and needs of BTPs. Our revised version of the DTs problem list (DT-BT) should in the next step be widely validated in multinational samples.

Exploring sleep disturbance among adults with primary or secondary malignant brain tumors and their caregivers

Background

Emerging evidence supports the clinical impact of sleep disturbance (SD) on cancer patients. This study aimed to determine the prevalence and predictors of SD in people with malignant brain tumors and caregivers, and explore any relationship between the patient-caregiver dyad's sleep.

Methods

Eighty-one adults with primary malignant (91%) or metastatic (9%) brain tumors and their family caregivers (n = 44) completed a series of self-report questionnaires, including the Pittsburgh Sleep Quality Index (PSQI), the Insomnia Severity Index, and the drowsiness item of The MD Anderson Symptom Inventory-Brain Tumor in an Australian ambulatory neuro-oncology setting. Participants were grouped by the PSQI cutoff (SD > 5), and binary logistic regression analyses were performed to identify risk factors.

Results

Of patients, 53% reported SD and 15% of those clinically significant insomnia, and 27% reported moderate to severe daytime drowsiness. Whereas anxiety, depression, fatigue, pain, neurocognitive symptoms, and antiemetic use were higher in patients with SD, fatigue and KPS were strong predictors of SD. In caregivers, 55% reported poor sleep and 13% clinical insomnia. Anxiety, caregiver burden, and comorbid illness were significantly associated with caregivers' SD. The individual's SD did not affect the chance of the other member of the patient-caregiver dyad experiencing SD.

Conclusions

More than half the sample had sleep disturbance, which was linked to many concomitant symptoms, such as fatigue in patients and anxiety in caregivers, potentially contributing to distress and functional impairment. Understanding underlying mechanisms of SD, the potential use of these clinical predictors in care settings, and options for management is warranted.

The Impact of the Timing of Health-Related Quality of Life Assessments on the Actual Results in Glioma Patients: A Randomized Prospective Study

Background: The aim of this study was to explore the impact of the timing of Health-Related Quality of Life (HRQoL) measurements in clinical care on the obtained HRQoL scores in glioma patients, and the association with feelings of anxiety or depression. Methods: Patients completed the European Organisation for Research and Treatment of Cancer (EORTC)’s Quality of Life Questionnaires (QLQ-C30 and QLQ-BN20), and the Hospital Anxiety and Depression Scale (HADS) twice. All patients completed the first measurement on the day of the Magnetic Resonance Imaging (MRI) scan (t = 0), but the second measurement (t = 1) depended on randomization; Group 1 (n = 49) completed the questionnaires before and Group 2 (n = 51) after the consultation with the physician. Results: median HRQoL scale scores on t0/t1 and change scores were comparable between the two groups. Between 8–58% of patients changed to a clinically relevant extent (i.e., ≥10 points) on the evaluated HRQoL scales in about one-week time, in both directions, with only 3% of patients remaining stable in all scales. Patients with a stable role functioning had a lower HADS anxiety change score. The HADS depression score was not associated with a change in HRQoL. Conclusions: Measuring HRQoL before or after the consultation did not impact HRQoL scores on a group level. However, most patients reported a clinically relevant difference in at least one HRQoL scale between the two time points. These findings highlight the importance of standardized moments of HRQoL assessments, or patient-reported outcomes in general, during treatment and follow-up in clinical trials.

Validation study of the Japanese version of MD Anderson Symptom Inventory for Brain Tumor module

OBJECTIVE

The MD Anderson Symptom Inventory for Brain Tumor (MDASI-BT) module is a widely used instrument for measuring symptom burden and interference of daily activities in brain tumor patients. This study aims to develop and validate its Japanese version (MDASI-BT-Japanese).

METHODS

Following forward and backward translation of the original MDASI-BT into Japanese, understandability and feasibility were assessed by cognitive debriefing. Subsequently, patients with brain tumors were asked to fill out MDASI-BT-Japanese and European Quality of Life-5 Dimensions (EQ-5D). Feasibility, reliability and validity of MDASI-BT-Japanese were assessed.

RESULTS

Cognitive debriefing confirmed overall ease of completion and good understandability. The study population composed of 140 patients with brain tumors (most commonly gliomas). The mean symptom severity score and mean interference score were 1.9 ± 1.7 and 2.8 ± 2.7, respectively. The top items included distress and drowsiness for symptom severity and general activity and work for interference. The median time required was 4 minutes (range, 0.5-30), and missing values were seen in 1%. Internal consistency was proven by excellent Cronbach's coefficient alpha (0.94 for symptom severity, 0.92 for interference). Test-retest reliability was assessed with acceptable intra-class correlation coefficient (mean, 0.76). Correlation efficient ranged between 0.7 and 0.9 for convergent validity. Known-group validity was confirmed by significantly different mean symptom severity score and mean interference score among patients with different performance status. As evidence of concurrent validity, MDASI-BT-Japanese correlated with EQ-5D in the hypothesized magnitude and direction.

CONCLUSIONS

The newly developed MDASI-BT-Japanese has demonstrated feasibility, reliability and validity in evaluation of clinical benefit in Japanese-speaking brain tumor patients.

Early imaging marker of progressing glioblastoma: a window of opportunity

PURPOSE

Therapeutic intervention at glioblastoma (GBM) progression, as defined by current assessment criteria, is arguably too late as second-line therapies fail to extend survival. Still, most GBM trials target recurrent disease. We propose integration of a novel imaging biomarker to more confidently and promptly define progression and propose a critical timepoint for earlier intervention to extend therapeutic exposure.

METHODS

A retrospective review of 609 GBM patients between 2006 and 2019 yielded 135 meeting resection, clinical, and imaging inclusion criteria. We qualitatively and quantitatively analyzed 2000+ sequential brain MRIs (initial diagnosis to first progression) for development of T2 FLAIR signal intensity (SI) within the resection cavity (RC) compared to the ventricles (V) for quantitative inter-image normalization. PFS and OS were evaluated using Kaplan-Meier curves stratified by SI. Specificity and sensitivity were determined using a 2 × 2 table and pathology confirmation at progression. Multivariate analysis evaluated SI effect on the hazard rate for death after adjusting for established prognostic covariates. Recursive partitioning determined successive quantifiers and cutoffs associated with outcomes. Neurological deficits correlated with SI.

RESULTS

Seventy-five percent of patients developed SI on average 3.4 months before RANO-assessed progression with 84% sensitivity. SI-positivity portended neurological decline and significantly poorer outcomes for PFS (median, 10 vs. 15 months) and OS (median, 20 vs. 29 months) compared to SI-negative. RC/V ratio ≥ 4 was the most significant prognostic indicator of death.

CONCLUSION

Implications of these data are far-reaching, potentially shifting paradigms for glioma treatment response assessment, altering timepoints for salvage therapeutic intervention, and reshaping glioma clinical trial design.

Repeat radiation with bevacizumab and minocycline in bevacizumab-refractory high grade gliomas: a prospective phase 1 trial

Introduction

There are no effective treatments for gliomas after progression on radiation, temozolomide, and bevacizumab. Microglia activation may be involved in radiation resistance and can be inhibited by the brain penetrating antibiotic minocycline. In this phase 1 trial, we examined the safety and effect on survival, symptom burden, and neurocognitive function of reirradiation, minocycline, and bevacizumab.

Methods

The trial used a 3 + 3 design for dose escalation followed by a ten person dose expansion. Patients received reirradiation with dosing based on radiation oncologist judgment, bevacizumab 10 mg/kg IV every two weeks, and oral minocycline twice a day. Symptom burden was measured using MDASI-BT. Neurocognitive function was measured using the COGSTATE battery.

Results

The maximum tolerated dose of minocycline was 400 mg twice a day with no unexpected toxicities. The PFS3 was 64.6%, and median overall survival was 6.4 months. Symptom burden and neurocognitive function did not decline in the interval between treatment completion and tumor progression.

Conclusions

Minocycline 400 mg orally twice a day with bevacizumab and reirradiation is well tolerated by physician and patient reported outcomes in people with gliomas that progress on bevacizumab.

Online Couple-Based Meditation Intervention for Patients With Primary or Metastatic Brain Tumors and Their Partners: Results of a Pilot Randomized Controlled Trial

OBJECTIVES

Although patients with primary and metastatic brain tumors and their partners are at risk of experiencing high symptom burden, they are often excluded from psychosocial intervention studies. Thus, we sought to examine the feasibility and preliminary efficacy of a couple-based meditation (CBM) program targeting symptom and well-being outcomes.

METHODS

Couples completed baseline measures assessing symptom and well-being outcomes and were randomized to the CBM or a usual care control group. Couples in the CBM groups attended four weekly (60 minutes each) therapist-led sessions that were delivered via FaceTime (Apple Inc, Cupertino, CA). The CBM program focused on cultivating mindfulness, compassion, gratitude and purpose, and integrated emotional disclosure exercises. Both groups were reassessed six and 12 weeks after baseline.

RESULTS

We approached 60 eligible dyads, of which 37 (62%) consented, 35 (95%) were randomized, and 22 (63%) completed all assessments. Couples in the CBM group attended a mean of 3.33 sessions (SD 1.09). For patients, significant group differences in favor of the CBM group were found for cognitive (d = 1.05) and general disease symptoms (d = 0.93), and relationship well-being (d = 0.68) and compassion (d = 0.96). No significant group differences were revealed for partners.

CONCLUSION

It seems to be feasible, acceptable, and possibly efficacious to deliver a dyadic intervention via FaceTime to brain tumor couples. Although both patients and partners in the CBM group rated the intervention as beneficial, significant group differences with medium-to-large effect sizes were only found for patients.

Hippocampal Avoidance During Whole-Brain Radiotherapy Plus Memantine for Patients With Brain Metastases: Phase III Trial NRG Oncology CC001

PURPOSE

Radiation dose to the neuroregenerative zone of the hippocampus has been found to be associated with cognitive toxicity. Hippocampal avoidance (HA) using intensity-modulated radiotherapy during whole-brain radiotherapy (WBRT) is hypothesized to preserve cognition.

METHODS

This phase III trial enrolled adult patients with brain metastases to HA-WBRT plus memantine or WBRT plus memantine. The primary end point was time to cognitive function failure, defined as decline using the reliable change index on at least one of the cognitive tests. Secondary end points included overall survival (OS), intracranial progression-free survival (PFS), toxicity, and patient-reported symptom burden.

RESULTS

Between July 2015 and March 2018, 518 patients were randomly assigned. Median follow-up for alive patients was 7.9 months. Risk of cognitive failure was significantly lower after HA-WBRT plus memantine versus WBRT plus memantine (adjusted hazard ratio, 0.74; 95% CI, 0.58 to 0.95; P = .02). This difference was attributable to less deterioration in executive function at 4 months (23.3% v 40.4%; P = .01) and learning and memory at 6 months (11.5% v 24.7% [P = .049] and 16.4% v 33.3% [P = .02], respectively). Treatment arms did not differ significantly in OS, intracranial PFS, or toxicity. At 6 months, using all data, patients who received HA-WBRT plus memantine reported less fatigue (P = .04), less difficulty with remembering things (P = .01), and less difficulty with speaking (P = .049) and using imputed data, less interference of neurologic symptoms in daily activities (P = .008) and fewer cognitive symptoms (P = .01).

CONCLUSION

HA-WBRT plus memantine better preserves cognitive function and patient-reported symptoms, with no difference in intracranial PFS and OS, and should be considered a standard of care for patients with good performance status who plan to receive WBRT for brain metastases with no metastases in the HA region.

Remarkable response of a patient with secondary glioblastoma to a histone deacetylase inhibitor

Secondary glioblastoma is a rare brain tumor characterized by a mutation in isocitrate dehydrogenase, which is reported to lead to epigenetic modification. Patients with secondary glioblastoma experience poor survival and quality-of-life outcomes due to the disease’s aggressiveness and a lack of targeted therapies. In this report, a patient with a secondary glioblastoma was treated with a histone deacetylase inhibitor, an epigenetic drug with potent anti-inflammatory properties, in addition to the standard regimen. The patient showed very favorable survival and quality-of-life measures, and a restoration of several neuro-metabolites as measured by spectroscopic magnetic resonance imaging.

In Search of the Optimal Outcome Measure for Patients with Advanced Cancer and Gastrointestinal Obstruction: A Qualitative Research Study

BACKGROUND

Gastrointestinal obstruction (GIO) is the most common indication for palliative surgical consultation in patients with advanced cancer. The purpose of this study is to delineate the symptom burden and experience of these patients.

PATIENTS AND METHODS

Twenty patients with advanced cancer and GIO described symptoms at time of surgical consultation. We analyzed the content of interview transcripts and ranked symptoms by frequency and according to an assessment of relevance conducted by an expert panel (surgeons, palliative care physicians, nurses, and patients/caregivers).

RESULTS

Among the 20 study patients, malignancy types included colorectal (n = 9), gastric (n = 4), urothelial/renal (n = 3), and other (n = 4), whereas sites of obstruction were the small bowel (n = 11), gastric outlet (n = 3), and large bowel (n = 6). Thirteen patients (65%) had received chemotherapy within 6 weeks. Imaging evidence of a primary/recurrent tumor was documented in 13 patients (65%), carcinomatosis in 11 (55%), and ascites in 16 (80%). Thirty patient symptoms were identified on qualitative interviewing. Seven GIO-specific items were identified as relevant by the expert panel and will be added to the core symptom assessment inventory for further testing.

CONCLUSIONS

We identified symptoms of importance that can be used to assess outcome after treatment of patients with advanced cancer and GIO. Testing for validity and reliability will be required before formal survey development.

The prevalence of altered body image in patients with primary brain tumors: an understudied population

Purpose

Body image (BI) is an important issue for cancer patients, as patients with BI concerns are susceptible to depression, anxiety, difficulty coping, and poor quality of life (QoL). While this concern has been documented in patients with other malignancies, no data exists of this QoL issue in patients with primary brain tumors (PBT).

Methods

A cross-sectional survey of 100 PBT patients was conducted on an IRB approved prospective protocol using structured questionnaires. Participants completed the body image scale (BIS), Appearance Scheme Inventory Revised (ASI-R), MD Anderson Symptom Inventory Brain Tumor (MDASI-BT), and Patient-Reported Outcomes Measurement Information System (PROMIS) Depression, Anxiety, and Psychosocial Impact Positive measures.

Results

The prevalence of clinically significant body image dissatisfaction (BIS ≥ 10) was 28% (95% CI 19–37%), median BIS score was 5 (range 0–27). The median ASI-R composite score was 2.9 (range 1.5–4.7). BIS was significantly correlated with the ASI-R (r = 0.53, 95% CI 0.37 to 0.65). The mean PROMIS Depression score was 48.4 (SD = 8.9), PROMIS Anxiety score was 49.4 (SD = 9.9), and PROMIS Psychosocial Illness Impact Positive score was 48.9 (SD = 9.7). BIS was significantly correlated with age, and trended with BMI and sex. The PROMIS Psychosocial Illness Impact Positive and PROMIS Anxiety scores were the most strongly related to BIS.

Conclusions

This study, the first to explore altered body image in PBT patients, revealed clinically significant body image dissatisfaction in nearly 1/3 of patients, similar to other malignancies. These findings underscore the potential contribution of disease and treatment-related body image concerns on psychosocial wellbeing in patients with PBT.

Early versus delayed postoperative radiotherapy for treatment of low-grade gliomas

BACKGROUND

This is an update of the review originally published in 2011 and first updated in 2015. In most people with low-grade gliomas (LGG), the primary treatment regimen remains a combination of surgery followed by postoperative radiotherapy. However, the optimal timing of radiotherapy is controversial. It is unclear whether to use radiotherapy in the early postoperative period, or whether radiotherapy should be delayed until tumour progression occurs.

OBJECTIVES

To assess the effects of early postoperative radiotherapy versus radiotherapy delayed until tumour progression for low-grade intracranial gliomas in people who had initial biopsy or surgical resection.

SEARCH METHODS

Original searches were run up to September 2014. An updated literature search from September 2014 through November 2019 was performed on the following electronic databases: the Cochrane Central Register of Controlled Trials (CENTRAL; 2019, Issue 11), MEDLINE via Ovid (September 2014 to November week 2 2019), and Embase via Ovid (September 2014 to 2019 week 46) to identify trials for inclusion in this Cochrane review update.

SELECTION CRITERIA

We included randomised controlled trials (RCTs) that compared early versus delayed radiotherapy following biopsy or surgical resection for the treatment of people with newly diagnosed intracranial LGG (astrocytoma, oligodendroglioma, mixed oligoastrocytoma, astroblastoma, xanthoastrocytoma, or ganglioglioma). Radiotherapy may include conformal external beam radiotherapy (EBRT) with linear accelerator or cobalt-60 sources, intensity-modulated radiotherapy (IMRT), or stereotactic radiosurgery (SRS).

DATA COLLECTION AND ANALYSIS

Three review authors independently assessed the trials for inclusion and risk of bias, and extracted study data. We resolved any differences between review authors by discussion. Adverse effects were also extracted from the study report. We performed meta-analyses using a random-effects model with inverse variance weighting.

MAIN RESULTS

We included one large, multi-institutional, prospective RCT, involving 311 participants; the risk of bias in this study was unclear. This study found that early postoperative radiotherapy was associated with an increase in time to progression compared to observation (and delayed radiotherapy upon disease progression) for people with LGG but did not significantly improve overall survival (OS). The median progression-free survival (PFS) was 5.3 years in the early radiotherapy group and 3.4 years in the delayed radiotherapy group (hazard ratio (HR) 0.59, 95% confidence interval (CI) 0.45 to 0.77; P < 0.0001; 311 participants; 1 trial; low-quality evidence). The median OS in the early radiotherapy group was 7.4 years, while the delayed radiotherapy group experienced a median overall survival of 7.2 years (HR 0.97, 95% CI 0.71 to 1.33; P = 0.872; 311 participants; 1 trial; low-quality evidence). The total dose of radiotherapy given was 54 Gy; five fractions of 1.8 Gy per week were given for six weeks. Adverse effects following radiotherapy consisted of skin reactions, otitis media, mild headache, nausea, and vomiting. Rescue therapy was provided to 65% of the participants randomised to delayed radiotherapy. People in both cohorts who were free from tumour progression showed no differences in cognitive deficit, focal deficit, performance status, and headache after one year. However, participants randomised to the early radiotherapy group experienced significantly fewer seizures than participants in the delayed postoperative radiotherapy group at one year (25% versus 41%, P = 0.0329, respectively).

AUTHORS' CONCLUSIONS

Given the high risk of bias in the included study, the results of this analysis must be interpreted with caution. Early radiation therapy was associated with the following adverse effects: skin reactions, otitis media, mild headache, nausea, and vomiting. People with LGG who underwent early radiotherapy showed an increase in time to progression compared with people who were observed and had radiotherapy at the time of progression. There was no significant difference in overall survival between people who had early versus delayed radiotherapy; however, this finding may be due to the effectiveness of rescue therapy with radiation in the control arm. People who underwent early radiation had better seizure control at one year than people who underwent delayed radiation. There were no cases of radiation-induced malignant transformation of LGG. However, it remained unclear whether there were differences in memory, executive function, cognitive function, or quality of life between the two groups since these measures were not evaluated.

Influence of Residual Disease Following Surgical Resection in Newly Diagnosed Glioblastoma on Clinical, Neurocognitive, and Patient Reported Outcomes

BACKGROUND

The influence of subtotal resection (STR) on neurocognitive function (NCF), quality of life, and symptom burden in glioblastoma is unknown. If bevacizumab preferentially benefits patients with STR is unknown.

OBJECTIVE

To examine these uncertainties.

METHODS

NCF and patient reported outcomes (PRO) were prospectively collected in NRG Oncology RTOG 0525 and 0825. Changes in NCF and PRO measures from baseline to prespecified times were examined by Wilcoxon test, and mixed effects longitudinal modeling, to assess differences between patients who received STR vs gross-total resection. Changes were also compared among STR patients on 0825 receiving placebo vs bevacizumab to assess for a preferential therapeutic effect. Overall survival between STR and gross-total resection patients was compared using the Kaplan-Meier method.

RESULTS

A total of 427 patients were eligible with STR present in 37%. At baseline, patients with STR had worse NCF, worse MD Anderson Symptom Inventory Brain Tumor Neurological Factor ratings (P = .004), and European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (P = .002). Longitudinal multivariate analysis associated STR with worse NCF (Hopkins Verbal Learning Test-Revised Delayed Recognition [P = .048], Trail Making Test Part A [P = .035], and Controlled Oral Word Association [P = .049]). One hundred eighty-three STR patients from 0825 were analyzed (89 bevacizumab, 94 placebo); bevacizumab failed to demonstrate improvement in select NCF or PRO measures.

CONCLUSION

STR patients had worse NCF and PROs before therapy. During adjuvant therapy, STR patients had worse objective NCF, despite accounting for tumor location. STR did not result in a detriment to OS. The addition of bevacizumab did not preferentially improve PRO or NCF outcomes in STR patients.

Assessing Discrepancies in Neurocognitive and Patient-Reported Measures of Brain Tumor Survivors

OBJECTIVES

To examine the association between performance-based neurocognitive and patient-reported cognitive function tests and identify characteristics that may explain observed discrepancies as a means to advance intervention development.

SAMPLE & SETTING

40 adults diagnosed with a primary brain tumor (PBT) (high-grade, n = 35) were recruited from two academic neuro-oncology clinics in North Carolina.

METHODS & VARIABLES

Eligibility included a Mini-Mental State Examination score of 24 or greater, having completed cancer treatment, and having tumor stability. Participants completed performance-based neurocognitive and patient-reported cognitive function, demographic, and symptom assessment tests at one time point.

RESULTS

Neurocognitive impairments included executive control, memory, and attention. Age, time since diagnosis, and tumor- or treatment-specific variables were not associated with neurocognitive or patient-reported cognitive function. Those reporting worse cognitive impairment tended also to report greater severity of PBT-specific and depressive symptoms.

IMPLICATIONS FOR NURSING

Patient-reported cognitive concerns warrant additional assessment for potential interventions to maintain function.

Identifying symptom recurrences in primary brain tumor patients using the MDASI-BT and qualitative interviews

Background

Identifying symptoms experienced throughout the disease trajectory is pivotal to understanding management of patient symptoms. Patient interviews to solicit input from those who have experienced these symptoms is one method to capture this perspective to validate symptoms included in patient reported outcomes (PRO) measures.

Methods

A thematic approach was used to identify themes within qualitative interviews. The MD Anderson Symptom Inventory- Brain Tumor (MDASI-BT) was completed by glioma patients. Descriptive statistics was used for analysis of the MDASI-BT.

Results

Thematic saturation was reached with 23 participants, with a median age of 53 (23–62), on treatment (57%) and diagnosed with a glioblastoma (48%). Patients endorsed 20 out of the 22 MDASI-BT symptoms (symptoms not reported: dry mouth, shortness of breath) during the interviews and with completion of the instrument (seizures and vomiting were not endorsed). Fatigue (55%), seizures (50%), and pain (50%) were common symptoms described by the sample. During treatment, more symptoms were identified with fatigue, hair loss, and nausea more problematic. Aside from itching and swelling (endorsed by 2 patients each), all other symptoms not included in the MDASI-BT instrument were endorsed by only one patient.

Conclusions

Completion of the MDASI-BT, found patients reported on average 6.8 symptoms with 14% of reported symptoms (mean = 3) rated as moderate to severe. The findings demonstrate how applicable the MDASI-BT is in capturing significant symptoms experienced and how important it is to utilize throughout ones’ care to manage symptoms effectively.

Moving from clinician-defined to patient-reported outcome measures for survivors of high-grade glioma

BACKGROUND

Persons with high-grade glioma face both neurological and cancer-related symptoms from the tumor itself and its treatment affecting their daily lives. Survival alone is not an adequate outcome, the quality of the survivorship experience needs to be regarded with equal importance. Patient-reported outcome (PRO) measures can be used to evaluate treatment effects and symptom management interventions.

PURPOSE

The aim of this review was to identify the use, challenges, and potential of PRO measures in survivors of high-grade glioma.

METHODS

A narrative expert opinion review was performed on the subject. In addition to our own experiences we searched PubMed, Cumulative Index to Nursing and Allied Health Literature, the Cochrane Library, and PsycINFO for brain tumor-specific PRO measures used in the population of adult patients with high-grade glioma, both original articles and reviews were included.

RESULTS

There are several PRO measures that have been validated for patients with primary brain tumors including high-grade glioma. PRO measures are used both in clinical trials to evaluate the effect of treatment on health-related quality of life, and in daily clinical practice for holistic needs assessment and symptom management. Common PRO measures used for patients with high-grade glioma are European Organization for Research and Treatment of Cancer general instrument for patients with cancer together with brain tumor module, Functional Assessment of Cancer Therapy-Brain, and MD Anderson Symptom Inventory for Brain Tumor. Neurologic and cognitive disorders often occur in patients with high-grade glioma, which affects patients' ability to self-report over time, making it more challenging in this population. PRO as a primary outcome seems underutilized.

CONCLUSION

For clinical research, PRO measures need to be used together with other clinical outcome measures rather than replacing traditional outcome measures. Moving to more use of PRO measures in survivorship care has potential to improve patient-caregiver-healthcare team communication, symptom management, and quality of care. Implementing PROs in survivorship care should also involve caregivers and a response based on the results.

Psychometric Evaluation of the Caregiver Needs Screen in Neuro-Oncology Family Caregivers

BACKGROUND AND PURPOSE

The informal care demands of primary malignant brain tumor (PMBT) patients include unique issues associated with neurological and cognitive symptoms. Existing caregiver needs questionnaires do not include these disease-specific symptoms, which are particularly distressing. Therefore, we have developed the neuro-oncology Caregiver Needs Screen (CNS) and evaluated its psychometric properties.

METHODS

The 32-item instrument was developed based on PMBT caregiver interviews (N = 109) and expert review. The CNS was tested along measures of depression, anxiety, burden, and mastery in 122 PMBT caregivers. Principal components analysis was used to examine item properties and internal structure. Internal consistency reliability and construct validity were assessed.

RESULTS

Six subscales were identified with internal consistency ranging between alpha = .653 and .857. Convergent validity was verified by moderate/high correlations between measures of caregiver well-being and CNS scale scores.

CONCLUSIONS

Findings provide preliminary evidence of reliability and validity for the CNS. This instrument can be useful when assessing caregivers' needs for supportive care.

Interventions to help support caregivers of people with a brain or spinal cord tumour

BACKGROUND

The diagnosis and treatment of a brain or spinal cord tumour can have a huge impact on the lives of patients and their families with family caregiving often resulting in considerable burden and distress. Meeting the support needs of family caregivers is critical to maintain their emotional and physical health. Although support for caregivers is becoming more widely available, large-scale implementation is hindered by a lack of high-quality evidence for its effectiveness in the neuro-oncology caregiver population.

OBJECTIVES

To assess the effectiveness of supportive interventions at improving the well-being of caregivers of people with a brain or spinal cord tumour. To assess the effects of supportive interventions for caregivers in improving the physical and emotional well-being of people with a brain or spinal cord tumour and to evaluate the health economic benefits of supportive interventions for caregivers.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL; 2018, Issue 7), MEDLINE via Ovid, and Embase via Ovid. We also handsearched relevant published conference abstracts (previous five years), publications in the two main journals in the field (previous year), searched for ongoing trials via ClinicalTrials.gov, and contacted research groups in the field. The initial search was in March 2017 with an update in August 2018 (handsearches completed in January 2019).

SELECTION CRITERIA

We included all randomised controlled trials (RCTs) where caregivers of neuro-oncology patients constituted more than 20% of the sample and which evaluated changes in caregiver well-being following any supportive intervention.

DATA COLLECTION AND ANALYSIS

Two review authors independently selected studies and carried out risk of bias assessments. We aimed to extract data on the outcomes of psychological distress, burden, mastery, quality of patient-caregiver relationship, quality of life, and physical functioning.

MAIN RESULTS

In total, the search identified 2102 records, of which we reviewed 144 in full text. We included eight studies. Four interventions focused on patient-caregiver dyads and four were aimed specifically at the caregiver. Heterogeneity of populations and methodologies precluded meta-analysis. Risk of bias varied, and all studies included only small numbers of neuro-oncology caregivers (13 to 56 participants). There was some evidence for positive effects of caregiver support on psychological distress, mastery, and quality of life (low to very low certainty of evidence). No studies reported significant effects on caregiver burden or quality of patient-caregiver relationship (low to very low certainty of evidence). None of the studies assessed caregiver physical functioning. For secondary outcomes (patient emotional or physical well-being; health economic effects), we found very little to no evidence for the effectiveness of caregiver support. We identified five ongoing trials.

AUTHORS' CONCLUSIONS

The eight small-scale studies included employed different methodologies across different populations, with low certainty of evidence overall. It is not currently possible to draw reliable conclusions regarding the effectiveness of supportive interventions aimed at improving neuro-oncology caregiver well-being. More high-quality research is needed on support for family caregivers of people diagnosed, and living, with a brain or spinal cord tumour.

Evaluation of the psychometric properties and minimally important difference of the MD Anderson Symptom Inventory for malignant pleural mesothelioma (MDASI-MPM)

BACKGROUND

Symptom assessment requires psychometrically validated questionnaires that are easy to use, relevant to the disease, and quick to administer. The MD Anderson Symptom Inventory for malignant pleural mesothelioma (MDASI-MPM) was adapted from the general (core) MDASI to assess the severity of cancer-related and treatment-related symptoms specific to patients with this condition. The MDASI-MPM includes the 13 core MDASI symptoms, which are experienced by most cancer patients, and 6 MPM-specific items developed via qualitative interviewing, a method favored by the US Food and Drug Administration for instrument item generation and development. Qualitative interviewing that summarizes the item generation and development for the MDASI-MPM is detailed in a separate report. The psychometric study reported here was the next step in developing the validation dossier for the MDASI-MPM.

RESULTS

In this secondary analysis of data from a Phase II trial, 248 patients provided MDASI-MPM data at multiple timepoints during therapy. Over time, fatigue, pain, shortness of breath, feeling of malaise, and muscle weakness were consistently the worst symptoms reported; symptoms interfered most with work and general activity and least with relations with others. Cronbach coefficient alpha values for all MDASI-MPM subscales were at least 0.88 at baseline and 0.91 during treatment, indicating good internal consistency reliability. Intraclass correlations of at least 0.86 for all MDASI-MPM subscales administered a cycle apart (n = 82) were indicative of good test-retest reliability. Correlations between MDASI-MPM subscales and LCSS-Meso scores were at least 0.70 (P < 0.001 for all comparisons). Patients with good performance status had significantly lower scores than did patients with poor performance status (all P < 0.05), supporting evidence for known-group validity and sensitivity. Effect-size differences were 0.69 and higher, indicating medium-to-large effects. The minimally important difference in the MDASI-MPM subscales ranged from 1.0 to 1.5 points on a 0-10 scale.

CONCLUSIONS

Symptoms specific to a particular cancer, treatment method, or treatment site can be added to the core MDASI to create a tailored, "fit for purpose" instrument. We found the MDASI-MPM to be a valid, reliable, and responsive (sensitive) instrument for assessing the severity of symptoms of patients with MPM and their interference in patients' daily functioning.

Impacts of Surgery on Symptom Burden and Quality of Life in Pituitary Tumor Patients in the Subacute Post-operative Period

Background: Pituitary tumors are rare but are associated with significant symptoms that impact patients' quality of life (QOL). Surgery remains one of the most effective treatment options for long term disease control and symptom benefit, but symptom, and quality of life recovery in the subacute period has not been previously reported. This study aimed to better understand the impact of surgery on patients' symptom burden and QOL in the subacute post-surgical period. Methods: Twenty-three adult patients with pituitary tumors undergoing surgical resection at University of North Carolina Cancer Hospital were enrolled in this study. M.D. Anderson Symptom Inventory Brain Tumor Module, European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-BN20 questionnaires were collected pre- and 1-month post- surgical resection and differences were analyzed for individual and groups of symptoms and QOL using Wilcoxon signed-rank tests. Results: Twenty adult patients had both pre-operation and post-operation follow-up visits; 60% had functional pituitary adenomas. Seven symptoms including fatigue, memory, vision, numbness, speaking, appearance, and weakness were significantly improved at the 1-month post-operation visit while one symptom, sleep, worsened. Global Health Status/QOL measurements was improved minimally from 63 (SD 25) at pre-operation to 67 (SD 22) at 1-month post-operation without statistical significance. Conclusions: This study demonstrated a rapid improvement of many symptoms in the subacute post-operative period in pituitary tumor patients. Disturbed sleep was identified as the only symptom to worsen post-operatively, encouraging potential prospective interventions to improve sleep, and subsequently improve the QOL in pituitary tumor patients following surgical intervention.

Quality of Life in Brain Cancer: Clinical Validation of the Mexican-Spanish Version of the EORTC QLQ-BN20 Questionnaire

Background: Overall survival (OS) of patients with Brain Cancer (BC) is slowly increasing. The disease itself and its treatments deeply impact patient Health-related quality of life (HRQL). Therefore, valid and reliable instruments are needed. In this study, the Mexican-Spanish version of the QLQ-BN20 instrument is psychometrically and clinically validated.

Methods: Patients with brain cancer (BC) (primary or metastatic) evaluated at a tertiary cancer center, were invited to respond to the questionnaire, as well as the core-module QLQ-C30. Tests to demonstrate the instrument's internal consistency, the association of HRQL scales with clinical variables and OS were investigated.

Results: One hundred and nineteen patients were included in this cohort: 77 women and 42 men (mean age, 46.2 years). Patients answered both instruments in < 30 min.

Good convergent [all correlation coefficients (CC) > 0.37] and discriminant validity was observed and was associated with significant overlap (CC 0.007–0.68). All four multi-item scales of QLQ-BN20 also demonstrated good reliability (Cronbach α > 0.7). Several scales of the QLQ-BN20 were significantly associated with performance status and a modified Recursive Partition Analysis. Of the possible scale correlations, 40 of 161 (24.8%) scales in both instruments, were significantly (directly or inversely) correlated. Visual disorders, Motor dysfunction, Seizures and Weakness of the legs presented association with OS (p < 0.05).

Conclusion: The Mexican-Spanish version of the BN20 instrument is valid and reliable and can be used in clinical trials in patients with BC. Some HRQL scales were associated with OS and could therefore be incorporated in future studies of prognostic models.

Assessment of baseline symptom burden in treatment-naïve patients with lung cancer: an observational study

BACKGROUND

Patients with newly diagnosed lung cancer who have not yet begun treatment may already be experiencing major symptoms produced by their disease. Understanding the symptomatic effects of cancer treatment requires knowledge of pretreatment symptoms (both severity and interference with daily activities). We assessed pretreatment symptom severity, interference, and quality of life (QOL) in treatment-naïve patients with lung cancer and report factors that correlated with symptom severity.

METHODS

This was a retrospective analysis of data collected at initial intake. Symptoms/interference were rated on the MD Anderson Symptom Inventory (MDASI) between 30 days prediagnosis and 45 days postdiagnosis. We examined symptom severity by disease stage and differences in severity by histology. Linear regression analyses identified significant predictors of severe pain and dyspnea.

RESULTS

Of 460 eligible patients, 256 (62%) had adenocarcinoma, 30 (7%) had small cell carcinoma, and 100 (24%) had squamous cell carcinoma; > 30% reported moderate-to-severe (rated ≥ 5, 0-10 scale) pretreatment symptoms. The most-severe were fatigue, disturbed sleep, distress, pain, dyspnea, sadness, and drowsiness. Symptoms affected work, enjoyment of life, and general activity (interference) and physical well-being (QOL) the most. Patients with advanced disease (n = 289, 63%) had more-severe symptoms. Cancer stage was associated with pain severity; both histology and cancer stage were associated with severe dyspnea.

CONCLUSION

One third of lung cancer patients were symptomatic at initial presentation. Quantification of pretreatment symptom burden can inform patient-specific palliative therapy and differentiate disease-related symptoms from treatment-related toxicities. Poorly controlled symptoms could negatively affect treatment adherence and therapeutic outcomes.

Central Nervous System Metastasis in Patients with HER2-Positive Metastatic Breast Cancer: Patient Characteristics, Treatment, and Survival from SystHERs

PURPOSE

Patients with HER2-positive metastatic breast cancer (MBC) with central nervous system (CNS) metastasis have a poor prognosis. We report treatments and outcomes in patients with HER2-positive MBC and CNS metastasis from the Systemic Therapies for HER2-positive Metastatic Breast Cancer Study (SystHERs).

EXPERIMENTAL DESIGN

SystHERs (NCT01615068) was a prospective, U.S.-based, observational registry of patients with newly diagnosed HER2-positive MBC. Study endpoints included treatment patterns, clinical outcomes, and patient-reported outcomes (PRO).

RESULTS

Among 977 eligible patients enrolled (2012-2016), CNS metastasis was observed in 87 (8.9%) at initial MBC diagnosis and 212 (21.7%) after diagnosis, and was not observed in 678 (69.4%) patients. White and younger patients, and those with recurrent MBC and hormone receptor-negative disease, had higher risk of CNS metastasis. Patients with CNS metastasis at diagnosis received first-line lapatinib more commonly (23.0% vs. 2.5%), and trastuzumab less commonly (70.1% vs. 92.8%), than patients without CNS metastasis at diagnosis. Risk of death was higher with CNS metastasis observed at or after diagnosis [median overall survival (OS) 30.2 and 38.3 months from MBC diagnosis, respectively] versus no CNS metastasis [median OS not estimable: HR 2.86; 95% confidence interval (CI), 2.05-4.00 and HR 1.94; 95% CI, 1.52-2.49]. Patients with versus without CNS metastasis at diagnosis had lower quality of life at enrollment.

CONCLUSIONS

Despite advances in HER2-targeted treatments, patients with CNS metastasis continue to have a poor prognosis and impaired quality of life. Observation of CNS metastasis appears to influence HER2-targeted treatment choice.

Pilot randomized, controlled trial of a dyadic yoga program for glioma patients undergoing radiotherapy and their family caregivers

Background

While the use of behavioral medicine in managing glioma patients' symptoms is not well studied, the high symptom burden in patients and their family caregivers is well established. We conducted a pilot randomized, controlled trial to examine the feasibility and preliminary efficacy of a dyadic yoga (DY) intervention as a supportive care strategy.

Methods

Glioma patients undergoing radiotherapy and their caregivers were randomized to a 12-session DY or waitlist control (WLC) group. Prior to radiotherapy and randomization, both groups completed measures of cancer-related symptoms (MD Anderson Symptom Inventory-Brain Tumor module), depressive symptoms (Center for Epidemiological Studies-Depression measure), fatigue (Brief Fatigue Inventory), and overall quality of life (QOL; Medical Outcomes Study 36-item short-form survey). Dyads were reassessed at the last day of radiotherapy.

Results

Twenty patients (mean age: 46 years, 50% female, 80% WHO grade IV and caregivers (mean age: 50 years, 70% female, 50% spouses) participated in the trial. A priori feasibility criteria were met regarding consent (70%), adherence (88%), and retention (95%) rates. Controlling for relevant covariates, change score analyses revealed clinically significant improvements for patients in the DY compared with the WLC group for overall cancer symptom severity (d = 0.96) and symptom interference (d = 0.74), depressive symptoms (d = 0.71), and mental QOL (d = 0.69). Caregivers in the DY group reported clinically significant improvements in depressive symptoms (d = 1.12), fatigue (d = 0.89), and mental QOL (d = 0.49) relative to those in the WLC group.

Conclusion

A DY intervention appears to be a feasible and beneficial symptom and QOL management strategy for glioma patients undergoing radiotherapy and their caregivers. An efficacy trial with a more stringent control group is warranted.

Prevalence of symptoms in glioma patients throughout the disease trajectory: a systematic review

BACKGROUND

Glioma patients suffer from a wide range of symptoms which influence quality of life negatively. The aim of this review is to give an overview of symptoms most prevalent in glioma patients throughout the total disease trajectory, to be used as a basis for the development of a specific glioma Patient Reported Outcome Measure (PROM) for early assessment and monitoring of symptoms in glioma patients.

METHODS

A systematic review focused on symptom prevalence in glioma patients in different phases of disease and treatment was performed in MEDLINE, CINAHL and EMBASE according to PRISMA recommendations. We calculated weighted means for prevalence rates per symptom.

RESULTS

The search identified 2.074 unique papers, of which 32 were included in this review. In total 25 symptoms were identified. The ten most prevalent symptoms were: seizures (37%), cognitive deficits (36%), drowsiness (35%), dysphagia (30%), headache (27%), confusion (27%), aphasia (24%), motor deficits (21%), fatigue (20%) and dyspnea (20%).

CONCLUSIONS

Eight out of ten of the most prevalent symptoms in glioma patients are related to the central nervous system and therefore specific for glioma. Our findings emphasize the importance of tailored symptom care for glioma patients and may aid in the development of specific PROMs for glioma patients in different phases of the disease.

Modification of existing patient-reported outcome measures: qualitative development of the MD Anderson Symptom Inventory for malignant pleural mesothelioma (MDASI-MPM)

PURPOSE

Malignant pleural mesothelioma (MPM) is an aggressive cancer of the lung pleura. The MD Anderson Symptom Inventory (MDASI) is a patient-reported outcome (PRO) measure of symptom burden, the combined impact of disease-related and treatment-related symptoms on functioning. Validated PRO measures may require modification for use in specific study populations. We sought to modify the MDASI for patients with MPM and create a fit-for-purpose symptom-burden measure for use in a clinical trial, according to US Food and Drug Administration guidance on PRO utilization to support labeling claims.

METHODS

A literature review for MPM symptoms was conducted. Patients with MPM were qualitatively interviewed about experiences of disease and treatment. Descriptive analysis identified symptoms and interference with functioning to define MPM-related symptom burden. An expert panel rated the relevance of identified symptoms to patients with MPM. Patients who received the investigational drug in a previous Phase I study were interviewed for drug-specific symptoms.

RESULTS

Literature review and interviews of 20 patients identified 31 MPM-related symptoms. A conceptual model of MPM-related symptom burden was developed. After expert-panel relevance review, five MPM-specific items and the 13 core MDASI symptoms met criteria for inclusion in a provisional MDASI-MPM for psychometric testing. Interviews with six patients identified six drug-specific symptoms; three were mentioned by multiple patients. Of these three, one was not in the core MDASI.

CONCLUSIONS

The MDASI-MPM has established content validity and, with the addition of one symptom item, is ready for psychometric testing as fit-for-purpose for a clinical trial of an investigational agent.

Palliative Care, End-of-Life Care, and Advance Care Planning in Neuro-oncology

PURPOSE OF REVIEW

Despite new therapeutic approaches, most patients with high-grade glioma face limited overall survival and have a high symptom burden throughout their disease trajectory, especially in the end-of-life phase. This article provides an overview of the role of palliative care in neuro-oncology. Management recommendations are made for neurologic symptoms in patients with advanced brain tumors, including headaches, nausea, and fatigue. Special attention is given to how and when to involve subspecialty palliative care and hospice services to improve symptom management during active tumor treatment and in the end-of-life phase of patients with brain tumors. Advance care planning and end-of-life goals should be addressed early in the disease trajectory; this article provides a road map for these discussions.

RECENT FINDINGS

The high symptom burden of patients with brain tumors affects their quality of life as well as their ability to make treatment decisions. It is therefore warranted to involve patients with high-grade glioma in treatment decision making early in the disease course, with a focus on end-of-life care and advance care planning. Research in other World Health Organization grade IV cancers has shown that the early involvement of specialty palliative care improves quality of life and caregiver satisfaction. Patients with brain tumors should be actively screened for fatigue, and underlying factors such as hormone deficiencies, low blood counts, and sleep issues should be addressed before focusing interventions for tumor- and treatment-related fatigue.

SUMMARY

Palliative care can address typical symptoms, such as fatigue, nausea, and headaches that have the potential to severely disable patients with brain tumors. Advance care planning should be introduced proactively and early in the disease trajectory to ensure a dignified death and improved caregiver bereavement.

Corticosteroid use endpoints in neuro-oncology: Response Assessment in Neuro-Oncology Working Group

Background

Corticosteroids are the mainstay of treatment for peritumor edema but are often associated with significant side effects. Therapies that can reduce corticosteroid use would potentially be of significant benefit to patients. However, currently there are no standardized endpoints evaluating corticosteroid use in neuro-oncology clinical trials.

Methods

The Response Assessment in Neuro-Oncology (RANO) Working Group has developed consensus recommendations for endpoints evaluating corticosteroid use in clinical trials in both adults and children with brain tumors.

Results

Responders are defined as patients with a 50% reduction in total daily corticosteroid dose compared with baseline or reduction of the total daily dose to ≤2 mg of dexamethasone (or equivalent dose of other corticosteroid); baseline dose must be at least 4 mg of dexamethasone daily (or equivalent dose of other corticosteroids) for at least one week. Patients must have stable or improved Neurologic Assessment in Neuro-Oncology (NANO) score or Karnofsky performance status score or Eastern Cooperative Oncology Group (ECOG) (Lansky score for children age <16 y), and an improved score on a relevant clinical outcome assessment tool. These criteria must be sustained for at least 4 weeks after baseline assessment to be considered a response, and are confirmed 4 weeks after that (ie, 8 wk after baseline assessment) to be considered a sustained response.

Conclusions

This RANO proposal for corticosteroid use endpoints in neuro-oncology clinical trials may need to be refined and will require prospective validation in clinical studies.

Dual-stimuli-responsive TiO x /DOX nanodrug system for lung cancer synergistic therapy

Biological applications of nanosheets are rapidly increasing currently, which introduces new possibilities to improve the efficacy of cancer chemotherapy and radiotherapy. Herein, we designed and synthesized a novel nano-drug system, doxorubicin (DOX) loaded titanium peroxide (TiO x ) nanosheets, toward the synergistic treatment of lung cancer. The precursor of TiO2 nanosheets with high specific surface area was synthesized by a modified hydrothermal process using the polymer P123 as a soft template to control the shape. TiO x nanosheets were obtained by oxidizing TiO2 nanosheets with H2O2. The anti-cancer drug DOX was effectively loaded on the surface of TiO x nanosheets. Generation of reactive oxygen species, including H2O2, ·OH and ·O2 -, was promoted from TiO x nanosheets under X-ray irradiation, which is effective for cancer radiotherapy and drug release in cancer cells. In this way, chemotherapy and radiotherapy were combined effectively for the synergistic therapy of cancers. Our results reinforce the DOX loaded TiO x nanosheets as a pH sensitive and X-ray controlled dual-stimuli-responsive drug release system. The cytotoxicity, cellular uptake, and intracellular location of the formulations were evaluated in the A549 human non-small cell lung cancer cell line. Our results showed that TiO x /DOX complexes exhibited a greater cytotoxicity toward A549 cells than free DOX. This work demonstrates that the therapeutic efficacy of DOX-loaded TiO x nanosheets is strongly dependent on their loading mode and the chemotherapeutic and radiotherapy effect is improved under X-ray illumination, which provides a significant breakthrough for future applications of TiO x as a light activated drug carrier in cancer chemotherapy and radiotherapy.

Sleep disturbance of adults with a brain tumor and their family caregivers: a systematic review

The high incidence and psychophysiological morbidities of sleep disturbance in cancer have been increasingly recognized. Yet, more detailed understanding of sleep disturbance and options for management have been neglected areas in both clinical care and research. Brain tumor patients have been particularly overlooked. A systematic search of the literature from 1990 to 2015 was performed to review sleep disturbance in adults with primary or secondary brain tumor and their family caregivers. Fifty eligible studies were identified, of which 12 focused on sleep, 37 reported sleep items within a health-related quality of life measure and 1 reported caregivers' sleep. No sleep intervention has been developed or tested for brain tumor patients. Sleep disturbance and somnolence were frequently reported as the most severely rated symptoms within health-related quality of life across the disease course or treatments, along with fatigue. However, sleep-focused studies yielded inconsistent results in small samples of mostly benign brain tumors in long-term remission from total tumor resection. The research using standardized, multifaceted sleep assessments, particularly in patients with malignant brain tumor and caregivers who are undergoing treatment, is seriously lacking. A more systematic examination of sleep disturbance is warranted to inform the development of better symptom management programs in this population.

Describing Symptom Burden and Functional Status at the Diagnosis of Leptomeningeal Metastasis

OBJECTIVES

To investigate the associations of primary cancer, tumor characteristics, and cancer treatment with symptom burden and functional status.

SAMPLE & SETTING

52 patients with leptomeningeal metastasis (LM) at the University of Texas MD Anderson Cancer Center in Houston.

METHODS & VARIABLES

Records of 52 patients were reviewed, and presenting symptoms were recorded. Mean differences in number and specific symptoms and functional status were explored. Correlations between age and overall number of symptoms with specific symptoms were assessed with Pearson correlations.

RESULTS

Pain was the most frequently reported symptom. Hormonal ablation therapy within six months of LM diagnosis was associated with a higher number of symptoms. Receiving biotherapy more than six months prior to an LM diagnosis was associated with pain, and cerebrospinal fluid leukocytosis was associated with a poor Karnofsky Performance Status score.

IMPLICATIONS FOR NURSING

Nurses caring for patients with advanced cancer can help ensure the highest possible quality of life by obtaining a careful history, assessing symptoms, and noting any changes since the last encounter.

Clinical trial endpoints for patients with gliomas

Malignant glioma represents a diverse set of molecularly heterogeneous diseases. Few therapeutic agents have been approved despite decades of clinical trials research and pre-clinical investigation. Attempts to refine neuroimaging criteria and recent discovery of the genomic profiles linking tumor subsets to survival outcomes have spurred discussion on a variety of new approaches in clinical trial design and relevant endpoints. Here we focus on those endpoints in clinical trial design for patients with primary glioma and related issues still to be resolved.

Health-related quality of life of cranial WHO grade I meningioma patients: are current questionnaires relevant?

BACKGROUND

The clinical relevance of Health-Related Quality of Life (HRQoL) in meningioma patients has been increasingly acknowledged in recent years. Various questionnaires have been used. However, almost none of these questionnaires has been particularly developed for and/or validated in this patient group. Therefore, the aim of this study was to assess the relevance and comprehensiveness of existing HRQoL questionnaires used in meningioma research and to assess the agreement between patients and health care professionals (HCPs) on the most relevant and important HRQoL issues.

METHODS

A systematic literature search, following the PRISMA statement, was conducted to identify all HRQoL questionnaires used in meningioma research. Semi-structured interviews were organized with patients and HCPs to (1) assess the relevance of all issues covered by the questionnaires (score 0-3: not relevant-highly relevant), (2) assess the ten most important issues, and (3) identify new relevant HRQoL issues.

RESULTS

Fourteen different questionnaires were found in the literature, comprising 140 unique issues. Interviews were conducted with 20 patients (median age 57, 71% female) and 10 HCPs (4 neurosurgeons, 2 neurologists, 2 radiotherapists, 1 rehabilitation specialist, 1 neuropsychologist; median experience 13 years). Meningioma patients rated 17-80% of the issues in each of the questionnaires as relevant, HCPs 90-100%. Patients and HCPs agreed on the relevance of only 49 issues (35%, Cohen's kappa: 0.027). Both patients and HCPs considered lack of energy the most important issue. Patients and HCPs suggested five additional relevant issues not covered by current HRQoL questionnaires.

CONCLUSIONS

Existing HRQoL questionnaires currently used in meningioma patients do not fully cover all relevant issues to these patients. Agreement between patients and HCPs on the relevance of issues was poor. Both findings support the need to develop and validate a meningioma-specific HRQoL questionnaire.

Association of genetic variants with fatigue in patients with malignant glioma

Background

Fatigue is a consistently reported, severe symptom among patients with gliomas throughout the disease trajectory. Genomic pathways associated with fatigue in glioma patients have yet to be identified.

Methods

Clinical factors (performance status, tumor details, age, gender) were collected by chart review on glioma patients with fatigue ("I have lack of energy" on Functional Assessment of Cancer Therapy-Brain), as well as available genotyping data. Candidate genes in clock and inflammatory pathways were identified from a literature review, of which 50 single nucleotide polymorphisms (SNPs) in 7 genes were available. Clinical factors and SNPs identified by univariate analyses were included in a multivariate model for moderate-severe fatigue.

Results

The study included 176 patients (median age = 47 years, 67% males). Moderate-severe fatigue was reported by 43%. Results from multivariate analysis revealed poor performance status and 2 SNPs were associated with fatigue severity. Moderate-severe fatigue was more common in patients with poor performance status (OR = 3.52, P < .01). For each additional copy of the minor allele in rs934945 (PER2) the odds of fatigue decreased (OR = 0.51, P < .05). For each additional copy of the minor allele in rs922270 (ARTNL2) the odds of fatigue increased (OR = 2.38, P < .01). Both of these genes are important in the circadian clock pathway, which has been implicated in diurnal preference, and duration and quality of sleep. No genes in the inflammatory pathway were associated with fatigue in the current study.

Conclusions

Identifying patients at highest risk for fatigue during treatment allows for improved clinical monitoring and enrichment of patient selection for clinical trials.

Relationship between symptom burden and health status: analysis of the MDASI-BT and EQ-5D

Background

Patients with glioma are highly symptomatic and often have functional limitations from the time of diagnosis. Measuring health status may have value in determining impact of disease. This study provided a description of health status and utility scores in glioma patients throughout the illness trajectory using the EQ-5D (a functional measure of general health status). Furthermore, it evaluated the information provided by the MD Anderson Symptom Inventory-Brain Tumor (MDASI-BT; a measure of symptom burden and interference) in describing health-related quality of life as assessed by the EQ-5D.

Methods

Glioma patients completed the EQ-5D and MDASI-BT. Disease and clinical details were collected by medical record review. Linear regression evaluated whether MDASI-BT scores adequately predict patient health outcomes measured by the EQ-5D.

Results

The sample included 100 patients (65% male, 78% with a glioblastoma, median age 52 [range, 20-75], 56% in active treatment). Seventy-two percent of patients reported functional limitations in at least 1 area. Extreme cases reported inability to perform usual activities (8%) and significant anxiety/depression (5%). The MDASI-BT neurologic factor and activity-related interference (walking/activity/work) explained 52% of the variability in the EQ-5D in this patient population while adjusting for the effect of tumor grade, recurrence status, and performance status.

Conclusions

The majority of glioma patients reported at least 1 functional limitation on the EQ-5D. Over half of the variance in the EQ-5D was explained by the MDASI-BT, performance status, tumor grade, and recurrence status. The resultant model demonstrates the significant contribution of symptom burden on health status in glioma patients.
