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

PURPOSE

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

MATERIALS AND METHODS

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

RESULTS

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

CONCLUSION

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

Patient reported function and symptom burden in breast cancer patients with CNS metastases

e18635

Background: Central nervous system (CNS) metastases are associated with decreased quality of life for patients with metastatic breast cancer (MBC). Collecting patient-reported outcome (PRO) data can identify patient needs and inform patient-focused interventions. IMPACT the Brain is a care coordination program that aims to improve access to multidisciplinary care for patients with MBC and CNS metastases. The purpose of this study is to report baseline PRO data obtained as part of this program. Methods: Patients with MBC and CNS metastases are referred for enrollment in the program. PROs and caregiver assessments are collected on a voluntary basis at baseline and every 3 months. We performed a retrospective review of the baseline PRO data to determine: (1) type and severity of cancer-related symptoms reported by patients and (2) degree of burden reported by caregivers. The PROMIS Cancer Function Brief 3D Profile measures physical function (PF), fatigue (Fat), and social participation (Soc) in patients with cancer; 50.0 is the population mean and higher scores indicate a greater degree of a trait. The MD Anderson Symptom Inventory Brain Tumor (MDASI-BT) measures severity of cancer-related symptoms including interference with daily life. A score > 4 represents moderate symptoms and > 6 severe symptoms. The mean of the interference items represents overall symptom distress. The Short Form Zarit Burden Interview (ZBI-12) evaluates caregiver burden; a score ≥ 10 suggests mild burden while > 20 suggests high burden. PRO scores were summarized using descriptive statistics. Results: Sixty patients were referred and 54 (90%) enrolled; median age was 53 years (range 31-81). 47 questionnaires were collected at baseline from 32 participants. Average PROMIS T-scores were 37.0 for PF (31.9-51.2), 59.9 for Fat (48.9-66.8), and 42.3 for Soc (32.8-57.1). Participants reported greatest difficulty with performing heavy housework and completing usual work. The mean symptom severity score reported on the MDASI-BT (n = 20) was 2.82 (SD 1.56). Fatigue was the most severe symptom (mean 5.2, SD 2.7) and 25% of patients reported moderate symptoms. The mean interference score was 3.9 (SD 2.66), with 20% of patients reporting moderate and 30% reporting severe overall symptom distress. 65% of caregivers (n = 17) had at least mild caregiver burden on the ZBI-12. Of those, almost half (45.5%) had a score consistent with high burden. Conclusions: Collecting baseline PROs was feasible and provided valuable information about the patient experience. Symptoms experienced by patients with MBC and CNS metastases, particularly fatigue, interfere with ability to carry out usual activities. The distress caused by these symptoms may not correlate with the severity reported by the patient. Given the prevalence of burden experienced by caregivers, further work is needed to explore relationships among symptom distress, symptom severity, and caregiver burden.

Exercise improves health-related quality of life sleep and fatigue domains in adult high- and low-grade glioma patients

PURPOSE

The impact of exercise on health-related quality of life (HRQOL) in patients with glioma remains unknown. We hypothesized that glioma patients with low exercise tolerance experience more distress in HRQOL sleep and fatigue domains than patients with high tolerance to exercise.

METHODS

Thirty-eight male and female patients with low- or high-grade glioma treated at a single tertiary care institution participated. Patients completed a validated telephone survey to determine their exercise habits before and following diagnosis. An unpaired t-test was run to measure the interaction between exercise tolerances on HRQOL functional and impairment domains.

RESULTS

Those with low pre-morbid physical activity levels had more distress in HRQOL sleep and fatigue domains. The effects were independent of plasma brain-derived neurotrophic factor (BDNF) levels and the degree of exercise did not appear to impact plasma BDNF in adult glioma patients.

CONCLUSIONS

The aim of this study was to examine the significance of exercise habits on perioperative functional outcomes in patients with low-grade or high-grade glioma. We found that glioma patients with low tolerance to exercise had more sleep disturbances and greater fatigue than glioma patients with high tolerance to exercise. Furthermore, exercise tolerance in the adult glioma population does not appear to impact plasma BDNF secretion.

Evaluating specialty referral, research involvement, and PROs in a CNS-involved metastatic breast cancer care coordination program

47

Background: Central nervous system (CNS) metastases are associated with decreased survival and quality of life for patients with metastatic breast cancer (MBC). Multi-disciplinary care can optimize outcomes. This project aims to improve access to coordinated care for patients with MBC and CNS metastases while assessing patient-reported outcomes (PROs) in the context of the multidisciplinary care experience. Methods: Patients with MBC and CNS metastases are referred and offered to enroll in our care coordination program. A team of specialists (breast medical oncology, breast cancer genetics, radiation oncology, neurosurgery, neuro-oncology, physical medicine and rehabilitation (PM&R), neuropsychology, and palliative care) supports a dedicated program coordinator who provides navigation, education, specialty referral, and clinical trial screening. A unique intake form developed for the program creates personalized, coordinated, and expedited referrals. PROs and caregiver assessments are collected on a voluntary basis using the following validated questionnaires: PROMIS Cancer Function Brief 3D Profile, MD Anderson Symptom Inventory Brain Tumor (MDASI), and Short Form Zarit Burden Interview (ZBI-12), a screening tool for caregiver burden. Results: Since May 2020, 43 patients were referred and a total of 40 patients (93%) were enrolled – 2 (5%) declined due to perceived burden of participation and 1 (2%) died before enrollment. The majority of patients were White (n = 34, 85%). Median time to program intake was 1 day (range: 0-8 days). Of the 43 patients referred, 17 (40%) consented to research studies in the metastatic setting. 11 were for an interventional trial (65%), while 9 consents were for non-interventional studies (53%). In addition to the initially referred specialty, 56 referrals were made across 7 sub-specialties; 37 patients (66%) were subsequently seen by a sub-specialist, most commonly radiation oncology (n = 9), PM&R (n = 9), neuro-oncology (n = 8), and neuropsychology (n = 8). Of the nine patients seen by PM&R, 5 completed the PROMIS Profile (55%). Similar completion rates were seen for the MDASI (13 of 23 surveys given, 56.5%) and ZBI-12 (13 of 26 surveys given, 50%) questionnaires. Conclusions: Implementation of a care coordination program for patients with MBC and CNS metastases allows for improved access to care across sub-specialties and supports participation in clinical research for a group of cancer patients historically underrepresented in research studies. Though completion of questionnaires is optional in this program, the rate of completion raises the question of whether this patient population faces unique challenges that make it difficult to complete questionnaires that are often required in research studies.

OTHR-13. IMPACT the brain: improving metastatic breast cancer patient access to coordinated treatment

Central nervous system (CNS) metastases are associated with decreased survival and quality of life for patients with metastatic breast cancer (MBC). Multi-disciplinary care can optimize outcomes. This project aims to improve access to coordinated care for patients with MBC and CNS metastases.

Patients with MBC and CNS metastases are referred and offered to enroll in our care coordination program. A team consisting of specialists (breast medical oncology, breast cancer genetics, radiation oncology, neurosurgery, neuro-oncology, physical medicine and rehabilitation (PM&R), neuropsychology, and palliative care) supports a dedicated program coordinator who provides navigation, education, specialty referral, and clinical trial screening. A unique intake form developed for the program creates personalized, coordinated, and expedited referrals. Patient-reported outcomes and caregiver burden assessments are collected.

Since May 2020, 43 patients were referred and a total of 40 patients (93%) were enrolled – 2 (5%) declined due to perceived burden of participation and 1 (2%) died before enrollment. 85% of patients were Caucasian (n = 34) and 15% were non-Caucasian (n=6). Median time to program intake was 1 day (range: 0–8 days). Of the 43 patients referred, 17 (40%) consented to research studies in the metastatic setting. 11 were for an interventional trial (65%), while 9 consents were for non-interventional studies (53%). In addition to the initially referred specialty, 56 referrals were made across 7 sub-specialties; 37 patients (66%) were subsequently seen by a sub-specialist, most commonly radiation oncology (n = 9), neuro-oncology (n=8), PM&R (n=8), and neuropsychology (n=8).

Implementation of a care coordination program for patients with MBC and CNS metastases is feasible. Further, it allows for improved access to care across sub-specialties and supports participation in clinical research for a group of cancer patients historically underrepresented in research studies.

BDNF, COMT, and DRD2 polymorphisms and ability to return to work in adult patients with low- and high-grade glioma

BACKGROUND

Cognitive and language dysfunction is common among patients with glioma and has a significant impact on survival and health-related quality of life (HRQOL). Little is known about the factors that make individual patients more or less susceptible to the cognitive sequelae of the disease. A better understanding of the individual and population characteristics related to cognitive function in glioma patients is required to appropriately stratify patients, prognosticate, and develop more efficacious treatment regimens. There is evidence that allelic variation among genes involved in neurotransmission and synaptic plasticity are related to neurocognitive performance in states of health and neurologic disease.

METHODS

We studied the association of single-nucleotide polymorphism variations in brain-derived neurotrophic factor (BDNF, rs6265), dopamine receptor 2 (DRD2, rs1076560), and catechol-O-methyltransferase (COMT, rs4680) with neurocognitive function and ability to return to work in glioma patients at diagnosis and at 3 months. We developed a functional score based on the number of high-performance alleles that correlates with the capacity for patients to return to work.

RESULTS

Patients with higher-performing alleles have better scores on neurocognitive testing with the Repeatable Battery for the Assessment of Neuropsychological Status and Stroop test, but not the Trail Making Test.

CONCLUSIONS

A better understanding of the genetic contributors to neurocognitive performance in glioma patients and capacity for functional recovery is necessary to develop improved treatment strategies based on patient-specific factors.

Health Related Quality of Life in Adult Low and High-Grade Glioma Patients Using the National Institutes of Health Patient Reported Outcomes Measurement Information System (PROMIS) and Neuro-QOL Assessments

Health related quality of life (HRQOL) measures have become increasingly important in the management of glioma patients in both research and clinical practice settings. Functional impairment is common in low-grade and high-grade glioma patients as the disease has both oncological and neurological manifestations. Natural disease history as well as medical or surgical treatment can negatively influence HRQOL. There are no universal standards for HRQOL assessment in glioma patients. In this study, we examine patient perspectives on functional outcome domains and report the prevalence of impairments rates using the National Institutes of Health (NIH) Patient Reported Outcomes Measurement Information System (PROMIS) and Neuro-QOL item banks as measures of HRQOL. Retrospective analysis of a prospectively collected dataset involving 79 glioma patients reveals that quality of life concerns are the most important consideration behind making decisions about treatment in 80.7% of patients. The prevalence of functional impairment by PROMIS and NEURO-QOL assessment is high, ranging from 28.6% in the physical function domain to 43.9% in the cognitive function domain. Pain and anxiety related to physical decline is higher in LGG patients compared to HGG patients. Aphasia severity also impacts HRQOL. The results of this study suggest that the PROMIS and NEURO-QOL assessments may be important HRQOL metrics for future use in larger clinical research and clinical trial settings.

Cognitive reserve and executive function: Effect on judgment of health and safety

Individuals with the same neurological conditions do not necessarily manifest the same behavioral presentation, which suggests differences in resilience and vulnerability among individuals, a concept known as cognitive reserve. This study sought to explore the relationship among cognitive reserve, executive functioning, and health and safety judgment among a sample of older adult inpatients in an extended medical care unit at a Veterans Health Administration hospital. We hypothesized that cognitive reserve, as determined by an estimate of premorbid intellectual ability, would act as a protective factor against poor judgment in older adults with executive dysfunction. Participants included 200 Veterans who completed a comprehensive neuropsychological assessment, including measures of health and safety judgment, executive functioning, global cognitive functioning, and premorbid intellectual ability. After controlling for global cognitive functioning, executive functioning abilities did not have an effect on judgment abilities among those with high estimated intellectual ability. However, executive functioning had a significant effect on judgment abilities among those with low estimated intellectual ability. Our results suggest that intact executive functioning is critical for making appropriate health and safety decisions for patients with lower measured intellectual abilities and provide further support for the cognitive reserve model. Clinical implications are also discussed.

Delirium Detection and Impact of Comorbid Health Conditions in a Post-Acute Rehabilitation Hospital Setting

Misdiagnosis and under-detection of delirium may occur in many medical settings. This is important to address as delirium clearly increases risk of morbidity and mortality in such settings. This study assessed whether Veterans who screened positive on a delirium severity measure (Memorial Delirium Assessment Scale; MDAS) differed from those with and without corresponding medical documentation of delirium in terms of cognitive functioning, psychiatric/medical history, and medication use. A medical record review of 266 inpatients at a VA post-acute rehabilitation unit found that 10.9% were identified as delirious according to the MDAS and/or medical records. Of the Veterans who screened positive on the MDAS (N = 19), 68.4% went undetected by medical screening. Undetected cases had a higher number of comorbid medical conditions as measured by the Age-Adjusted Charlson Index (AACI) scores (median = 9, SD = 3.15; U = 5.5, p = .003) than medically documented cases. For Veterans with a score of 7 or greater on the AACI, the general relative risk for delirium was 4.46. Delirium is frequently under-detected in a post-acute rehabilitation unit, particularly for Veterans with high comorbid illness. The relative risk of delirium is up to 4.46 for those with high medical burden, suggesting the need for more comprehensive delirium screening in these patients.

Oncology nurses' experiences regarding patients' use of complementary and alternative therapies

In their search for information and in making decisions about complementary and alternative therapies, patients will turn to oncology nurses. How oncology nurses respond to the patient's questions or comments can have an impact on the decision a patient makes about pursuing a particular therapy or whether the patient feels supported. The impetus for this work was the desire to understand how oncology nurses are responding to the patient trend of using complementary and alternative therapies. Twenty-eight nurses were interviewed over the telephone and a content analysis was completed from the transcribed interviews. The nurses who participated in this study regularly engaged in conversations with patients about complementary therapies and were aware of the reasons patients pursued these therapies. Conversations about alternative therapies occurred less frequently, but often created turmoil for the nurse. The nurses thought they had a role in maintaining an open dialogue about therapies, but felt their knowledge about particular therapies was limited. Obtaining information was a challenge and they often learned about specific therapies from patients and the popular media. Turmoil arose for nurses most often with regards to patients pursuing ingested therapies or alternative therapies. Nurses suggested complementary therapies to patients, but usually waited for patients to raise the topic of alternative therapies. Providing support to patients, whatever course they are choosing to pursue, was seen as an important nursing role.

Oncology nurses' perspectives on unconventional therapies

Unconventional therapies have become increasingly popular with health care consumers in recent years. As patients seek information and attempt to make decisions about unconventional therapies, they often turn to nurses, asking their opinion about certain therapies. The nurse's attitudes and beliefs about unconventional therapies very likely will influence the response to the patient's inquiries. This work represents the findings of interviews with 48 nurses regarding their perspectives on unconventional therapies. Without exception, all nurses interviewed emphasized the need for information regarding unconventional therapies to be readily available for patients and health care professionals. The other themes identified in the interviews included the following: various people use unconventional therapies; people seek unconventional therapies for a variety of reasons; communication about unconventional therapies needs to be open; and conventional and unconventional practitioners ought to work collaboratively. The participants interviewed saw a clearly defined role for nurses regarding unconventional therapies.
