Neurodegenerative disease pathways are perturbed in patients with cancer who self-report cognitive changes and anxiety: A pathway impact analysis.

BACKGROUND: Cancer-related cognitive impairment (CRCI) and anxiety co-occur in patients with cancer. Little is known about mechanisms for the co-occurrence of these two symptoms. The purposes of this secondary analysis were to evaluate for perturbed pathways associated with the co-occurrence of self-reported CRCI and anxiety in patients with low versus high levels of these two symptoms and to identify potential mechanisms for the co-occurrence of CRCI and anxiety using biological processes common across any perturbed neurodegenerative disease pathways. METHODS: Patients completed the Attentional Function Index and the Spielberger State-Trait Anxiety Inventory six times over two cycles of chemotherapy. Based on findings from a previous latent profile analysis, patients were grouped into none versus both high levels of these symptoms. Gene expression was quantified, and pathway impact analyses were performed. Signaling pathways for evaluation were defined with the Kyoto Encyclopedia of Genes and Genomes database. RESULTS: A total of 451 patients had data available for analysis. Approximately 85.0% of patients were in the none class and 15.0% were in the both high class. Pathway impact analyses identified five perturbed pathways related to neurodegenerative diseases (i.e., amyotrophic lateral sclerosis, Huntington disease, Parkinson disease, prion disease, and pathways of neurodegeneration-multiple diseases). Apoptosis, mitochondrial dysfunction, oxidative stress, and endoplasmic reticulum stress were common biological processes across these pathways. CONCLUSIONS: This study is the first to describe perturbations in neurodegenerative disease pathways associated with CRCI and anxiety in patients receiving chemotherapy. These findings provide new insights into potential targets for the development of mechanistically based interventions.

The effectiveness of psychoeducational interventions on caregiver-oriented outcomes in caregivers of adult cancer patients: A systematic review and meta-analysis.

OBJECTIVE: Cancer caregiving can result in increased psychosocial distress and poor health-related quality of life (QOL). Psychoeducation has been shown to be effective in enhancing caregiving-oriented outcomes. A systematic assessment of the overall effect of psychoeducational intervention (PEI) and identification of individual intervention characteristics that may contribute to the effectiveness of PEI is needed. METHODS: For this meta-analysis, relevant articles were identified through electronic databases using key search terms and their medical subject heading such as "family caregiver," "cancer," and "psychoeducational intervention." RESULTS: Twenty-eight controlled trials with 3876 participants were included. PEIs had beneficial effect on depression (Standardized Mean Difference [SMD] -0.26; 95% CI = -0.50 to -0.01, p < 0.04), anxiety (SMD -0.41; 95% CI = -0.82 to 0.01, p < 0.05), caregiver burden (SMD -0.84; 95% CI = -1.22 to -0.46, p < 0.0001) and QOL (SMD 0.59, 95% CI 0.24-0.93; p < 0.0009) at the immediate post-intervention period. At longer-term follow-up, the effectiveness of PEI was maintained on QOL (SMD 0.39, 95% CI = -0.00 to -0.77, p < 0.05), and anxiety (SMD -0.57; 95% CI = -1.09 to -0.06, p < 0.03). Moderation analysis showed that intervention characteristics such as studies conducted in high-income countries, group intervention and studies that focused on specific and mixed cancers explain some of the high variations observed among the included studies. CONCLUSIONS: PEI may benefit caregivers of cancer patients through the significant effects on caregiver burden, QOL, anxiety, and depression. The findings from the moderation analysis may be important for the design of future interventions.

Patient perceptions of altering chemotherapy treatment due to peripheral neuropathy.

PURPOSE: Clinical practice guidelines recommend altering neurotoxic chemotherapy treatment in patients experiencing intolerable chemotherapy-induced peripheral neuropathy (CIPN). The primary objective of this survey was to understand patient's perspectives on altering neurotoxic chemotherapy treatment, including their perceptions of the benefits of preventing irreversible CIPN and the risks of reducing treatment efficacy. METHODS: A cross-sectional online survey was distributed via social networks to patients who were currently receiving or had previously received neurotoxic chemotherapy for cancer. Survey results were analyzed using descriptive statistics and qualitative analysis. RESULTS: Following data cleaning, 447 participants were included in the analysis. The median age was 57 years, 93% were white, and most were from the UK (53%) or USA (38%). Most participants who were currently or recently treated expected some CIPN symptom resolution (86%), but 45% of those who had completed treatment more than a year ago reported experiencing no symptom resolution. Participants reported that they would discontinue chemotherapy treatment for less severe CIPN if they knew their symptoms would be permanent than if symptoms would disappear after treatment. Most patients stated that the decision to alter chemotherapy or not was usually made collaboratively between the patient and their treating clinician (61%). The most common reason participants were reluctant to talk with their clinician about CIPN was fear that treatment would be altered. Participants noted a need for improved understanding of CIPN symptoms and their permanence, better patient education relating to CIPN prior to and after treatment, and greater clinician understanding and empathy around CIPN. CONCLUSIONS: This survey highlights the importance of shared decision-making, including a consideration of both the long-term benefits and risks of altering neurotoxic chemotherapy treatment due to CIPN. Additional work is needed to develop decision aids and other communication tools that can be used to improve shared decision making and help patients with cancer achieve their treatment goals.

An Evaluation of the Multifactorial Model of Cancer-Related Cognitive Impairment.

BACKGROUND: Up to 45% of patients report cancer-related cognitive impairment (CRCI). A variety of characteristics are associated with the occurrence and/or severity of CRCI. However, an important gap in knowledge of risk factors for CRCI is the relative contribution of each factor. The multifactorial model of cancer-related cognitive impairment (MMCRCI) is a conceptual model of CRCI that can be used to evaluate the strength of relationships between various factors and CRCI. OBJECTIVES: The purpose of this study was to use structural regression methods to evaluate the MMCRCI using data from a large sample of outpatients receiving chemotherapy ( n = 1,343). Specifically, the relationships between self-reported CRCI and four MMCRCI concepts (i.e., social determinants of health, patient-specific factors, treatment factors, and co-occurring symptoms) were examined. The goals were to determine how well the four concepts predicted CRCI and determine the relative contribution of each concept to deficits in perceived cognitive function. METHODS: This study is part of a larger, longitudinal study that evaluated the symptom experience of oncology outpatients receiving chemotherapy. Adult patients were diagnosed with breast, gastrointestinal, gynecological, or lung cancer; had received chemotherapy within the preceding 4 weeks; were scheduled to receive at least two additional cycles of chemotherapy; were able to read, write, and understand English; and gave written informed consent. Self-reported CRCI was assessed using the attentional function index. Available study data were used to define the latent variables. RESULTS: On average, patients were 57 years of age, college educated, and with a mean Karnofsky Performance Status score of 80. Of the four concepts evaluated, whereas co-occurring symptoms explained the largest amount of variance in CRCI, treatment factors explained the smallest amount of variance. A simultaneous structural regression model that estimated the joint effect of the four exogenous latent variables on the CRCI latent variable was not significant. DISCUSSION: These findings suggest that testing individual components of the MMCRCI may provide useful information on the relationships among various risk factors, as well as refinements of the model. In terms of risk factors for CRCI, co-occurring symptoms may be more significant than treatment factors, patient-specific factors, and/or social determinants of health in patients receiving chemotherapy.

Psychosocial and supportive care needs of individuals with advanced myeloma.

Purpose: The purpose of this qualitative study is to understand, from the patient's perspective, their experience of living with advanced multiple myeloma, the psychosocial impact, and needs for support in managing and adapting to this illness. Methods: An interpretive descriptive approach was used. Individual semi-structured telephone interviews were conducted with each participant, which focused on eliciting their descriptions of psychosocial issues and concerns, as well as the supports they use for coping with cancer. Transcripts were analyzed using interpretive description, resulting in the generation of common themes that represented the data. Results: The sample comprised twelve adults with a diagnosis of advanced multiple myeloma who had undergone at least three lines of treatment or were transfusion dependent. All participants were receiving ambulatory care for their myeloma in Toronto, Ontario, Canada. Four themes were generated: (1) confusion about the diagnosis and treatment options; (2) challenges in finding relevant information; (3) dealing with the chronicity of treatment side effects; (4) social support as critical for coping with the life-threat of multiple myeloma. Conclusion: Findings suggest that the psychosocial impact of living with advanced multiple myeloma is greatly impacted by one's ability to understand the complexities of the diagnosis and access supports to cope with its physical and emotional consequences. Clinical interventions specifically tailored to meeting the information and support needs of this population are needed.

Reflection on moving research forward during COVID-19: Strategies to continue, conclude and commence.

The COVID-19 pandemic required oncology nursing researchers to immediately and drastically adjust their research activities. During the 33rd Annual CANO/ ACIO Conference Roundtable Workshop October 2021 - Moving Research Forward During COVID-19, oncology nurses gathered to share and discuss strategies they will continue, conclude, and commence when leading research during and beyond the pandemic. Workshop participants identified the use of low technology, such as telephone and virtual calls without video, as a valuable data collection strategy they will continue for individual interviews. In contrast, attendees expressed their desire to stop conducting virtual focus groups when public health measures are lifted. Oncology nurses indicated an interest in beginning to use a hybrid in-person/virtual data collection approach and incorporate some technological features, such as QR codes, for recruiting participants. Workshop attendees also reflected on the impact of COVID-19 on oncology nursing practice and education, highlighting future research priorities and considerations.

The effect of mind-body exercise on cognitive function in cancer survivors: A systematic review.

Objective: Cancer-related cognitive impairments experienced by cancer survivors cause many to seek non-pharmacological intereventions to manage these symptoms. The aim of this systematic review was to evaluate the effects of one such intervention, mindbody exercise (MBE), on cognitive function in cancer survivors. Design: Searches for relevant studies were conducted in four electronic databases, including PubMed, Embase, Scopus, and Web of Science. The Joanna Briggs Institute and Jadad scales were utilized to evaluate the quality of the selected studies. Results: Eleven studies including 1,032 participants, published between 2006 and 2019, were selected for review based on specific inclusion criteria. Our results indicated that interventions including, yoga, tai chi, and qigong may improve objective and subjective cognitive function in cancer survivors. Conclusion: Cancer survivors experiencing cognitive symptoms may benefit from participation in MBE. Adequately powered randomized controlled trials are required to establish the short- and long-term effects of MBE on cognitive functioning.

Patient and clinician perspectives of desired features for a web-based self-management program (icanmanage.ca): exposing patients "hard work" of managing acute cancer.

PURPOSE: People with cancer benefit from self-management support, but report limitations in the type/amount of support they receive from healthcare professionals during cancer treatment. To intervene in this critical period, our team is developing a web-based self-management system, called I Can Manage Cancer (ICMC). The purpose of this paper is to report patient and clinician perspectives on the preferred features and functions in a self-management system that informed the development of the ICMC program. METHODS: We used descriptive qualitative methods, conducting interviews with people diagnosed with cancer (n = 16) and focus groups with cancer clinicians (n = 19). Data were thematically analyzed using the NVivo qualitative software. FINDINGS: People with cancer describe engaging in hard work when employing cancer self-management. Our findings lend insight into features and functions they deem vital in a self-management system to support this work. Based on patient and clinician accounts, we developed three themes describing specific content and design features for the ICMC program to support self-management needs of people with cancer during the acute phase of treatment: (1) being able to connect, observe, and learn from others; (2) the ability to tailor and customize information; and (3) the capacity to track symptoms over time. Clinicians and patients emphasized the need to optimize all available resources to support people with cancer as they engage in the work to manage their diagnosis. CONCLUSIONS: Our findings describe the how peoples' cancer experiences and the gaps in self-management care can be enhanced by specific features and functions within the ICMC.

Late cognitive outcomes among allogeneic stem cell transplant survivors: follow-up data from a 6-year longitudinal study.

CONTEXT: Survivors of allogeneic hematopoietic stem cell transplantation (alloHCT) may experience cognitive impairment over time post-treatment, but early identification of these individuals is limited. OBJECTIVES: We previously reported a prospective evaluation of cognitive functioning over the first 6 months of alloHCT. Here, we report an extension of this study, with specific aims to (1) evaluate the trajectory of cognitive outcomes over the first 6 years post-alloHCT, and (2) determine the extent to which late cognitive impairment is predicted by earlier impairment. METHODS: Participants completed objective and subjective cognitive measures before alloHCT, and at 100 days, 6 months, and 6 years post-alloHCT. Outcome trajectories were determined using linear mixed effects models. Relationships between early and late cognitive impairment were assessed using logistic regression and receiver operator curves. RESULTS: This analysis is based on longitudinal data from 59 participants, of whom 20 provided data at 6-year follow-up. Longitudinal models revealed an overall stability of cognitive outcomes over time, except for psychomotor efficiency/processing speed performance, which significantly improved (p = .049). However, poor learning/memory and cognitive complaints were persistently observed. At 6 years, 40% of relapse-free survivors met the impairment criteria. Impairment at 100 days was associated with impairment 6 years (OR = 20.00, p = .028) and demonstrated good accuracy in classifying those who were impaired and not impaired at 6 years (AUC = .79; 95% CI = .56-1.00). CONCLUSION: Poor cognitive outcomes among long-term alloHCT survivors are associated with cognitive functioning during the early post-treatment period. Early identification of survivors likely to experience poor cognitive outcomes may be possible, enabling timely intervention to mitigate long-term negative impacts.

Cancer-related cognitive impairment in patients with non-central nervous system malignancies: an overview for oncology providers from the MASCC Neurological Complications Study Group.

Cancer-related cognitive impairment (CRCI) is commonly experienced by individuals with non-central nervous system cancers throughout the disease and treatment trajectory. CRCI can have a substantial impact on the functional ability and quality of life of patients and their families. To mitigate the impact, oncology providers must know how to identify, assess, and educate patients and caregivers. The objective of this review is to provide oncology clinicians with an overview of CRCI in the context of adults with non-central nervous system cancers, with a particular focus on current approaches in its identification, assessment, and management.

Consortium Building for Nurse Scientists Interested in Symptoms Research in the Era of Precision Health.

PURPOSE: This article aims to provide perspectives on the establishment of a consortium for nurse scientists with similar career trajectories interested in cancer-related symptoms (CRS) research. Hereby, we describe the development of and recent outcomes from the CRS consortium, the lessons learned in establishing the consortium, and future directions to advance the science of CRS. MODEL AND METHODS: New and innovative strategies are needed to address the complexity of CRS research. A CRS consortium was created to allow a mechanism for oncology nurse scientists with varying expertise to collaborate to advance CRS research. The National Institutes of Health (NIH) Symptom Science Model (SSM) guides the research of the CRS Consortium. DISCUSSION AND CONCLUSIONS: A need for improved CRS assessment and management has been identified. The CRS consortium was created as a collaborative think tank to begin to address this need. Guided by the NIH SSM, CRS consortium members have worked to define symptom phenotypes, enhance understanding of the biologic mechanisms that can contribute to symptom phenotypes, and develop tailored interventions to improve symptom management. Dissemination of the CRS consortium efforts involve publications and presentations. CLINICAL IMPLICATIONS: Nurse scientists interested in symptom science and biobehavorial research face many challenges on how to initiate and sustain independent programs of research. Through the formation of a CRS consortium, oncology nurse scientists can work together to address identified issues in symptom measurement and management.

Biological predictors of chemotherapy-induced peripheral neuropathy (CIPN): MASCC neurological complications working group overview.

Chemotherapy-induced peripheral neuropathy (CIPN) is a common and debilitating condition associated with a number of chemotherapeutic agents. Drugs commonly implicated in the development of CIPN include platinum agents, taxanes, vinca alkaloids, bortezomib, and thalidomide analogues. As a drug response can vary between individuals, it is hypothesized that an individual's specific genetic variants could impact the regulation of genes involved in drug pharmacokinetics, ion channel functioning, neurotoxicity, and DNA repair, which in turn affect CIPN development and severity. Variations of other molecular markers may also affect the incidence and severity of CIPN. Hence, the objective of this review was to summarize the known biological (molecular and genomic) predictors of CIPN and discuss the means to facilitate progress in this field.

Experience of Care Among Adults With Acute Leukemia Near the End of Life: A Scoping Review.

Background: Acute leukemia is a cancer of the blood and bone marrow with a high symptom burden and a high mortality rate in adults. The quality of end-of-life care among this patient population is deemed to be low based on health care administrative data, though the patient experience is not included in this evaluation. Objective: This scoping review aims at exploring and mapping the current research literature on the experience of care among adults with incurable acute leukemia near the end of life. Design: The JBI framework guided our scoping review, and the protocol was prospectively registered in the Open Science Forum. Results: A total of 5661 unique articles were screened for title and abstract, and 44 were selected for full text. After a manual search, five studies published in seven articles were selected for data extraction, including three qualitative and two quantitative studies. Two studies used family caregivers as patient proxies, two studies engaged patients directly, whereas one study obtained data from patients and family caregivers. Patient care in acute settings was reported in all studies, with most patients dying in acute care settings. Patients and family caregivers often valued an open and honest approach, with sufficient time for dialogue with their providers. Discussions about prognosis, palliative care, and hospice care were often late or incomplete. The medicalization of end-of-life care, including intensive care unit admissions and invasive medical procedures, were viewed as the norm by some providers, though perceived as distressing for both patients and their loved ones. Conclusions: Adults with acute leukemia face significant challenges in accessing high-quality end-of-life care brought about by the complex nature of their disease and its treatment. A systematic exploration of the end-of-life experience among these patients through direct patient engagement or by way of patient reporting proxies is needed.

Cognitive Symptoms Across Diverse Cancers.

Importance: Psychosocial health services for adults with cancer should include support for cognitive symptoms and symptom clusters. Objective: To characterize the frequency and severity of cognitive symptoms and to identify demographic and clinical risk factors associated with moderate to severe cognitive symptoms among outpatient adults with cancer seeking psychosocial support. Design, Setting, and Participants: This cross-sectional study analyzed data from routine patient-reported symptom screening during clinic appointments at the Princess Margaret Cancer Centre in Toronto, Canada, between January 1, 2013, and December 31, 2019. Participants were outpatient adults (aged ≥18 years) with diverse cancer diagnoses who endorsed interest in receiving psychosocial support from a health care team member. Data analysis was performed from April 2020 to June 2024. Main Outcomes and Measures: The presence and severity of cognitive symptoms as self-rated by participants were characterized across 12 cancer types: brain or central nervous system (CNS), breast, gastrointestinal, head and neck, gynecological, thyroid, lung and bronchus, sarcoma, genitourinary, melanoma, hematological, and all other cancers. Multivariable logistic regression was used to explore the associations between demographic, clinical, and symptom factors and moderate to severe cognitive symptoms. Results: Across the sample of 5078 respondents (2820 females [55.5%]; mean [SD] age at time of survey, 56.0 [14.1] years) requesting psychosocial support, 3480 (68.5%) reported cognitive symptoms of any severity, ranging from 59.5% in sarcoma to 86.5% in brain or CNS cancer. Moderate to severe cognitive symptoms were reported by 1544 patients (30.4%), with the proportions being 51.3% for patients with brain or CNS, 37.0% for breast, 36.2% for thyroid, 30.9% for melanoma, 29.6% for head and neck, 28.3% for gastrointestinal, 28.2% for hematological, 28.1% for gynecological, 24.9% for lung and bronchus, 24.9% for sarcoma, 21.0% for genitourinary, and 26.8% for all other cancers. Across the entire sample, moderate to severe cognitive symptoms were associated with recurrence or progression involving the CNS (odds ratio [OR], 2.62; 95% CI, 1.80-3.81), depression (OR, 1.92; 95% CI, 1.59-2.31), tiredness (OR, 1.82; 95% CI, 1.52-2.19), drowsiness (OR, 1.64; 95% CI, 1.39-1.93), anxiety (OR, 1.57; 95% CI, 1.30-1.89), shortness of breath (OR, 1.38; 95% CI, 1.16-1.61), female sex (OR, 1.33; 95% CI, 1.14-1.56), first-line chemotherapy received (OR, 1.22; 95% CI, 1.05-1.41), and metastatic disease at diagnosis (OR, 0.74; 95% CI, 0.61-0.89). Within individual cancer types, tiredness and depression were consistently associated with moderate to severe cognitive symptoms. Conclusions and Relevance: This cross-sectional study found that cognitive symptoms were frequently reported by patients across a wide range of cancer types; higher severity of cognitive symptoms was consistently associated with higher symptom burden. The findings could be used to inform decision-making regarding access to cognitive screening, assessment, and supportive care in outpatient oncology clinics.

Impact of Cognitive Rehabilitation on Cognitive and Functional Outcomes in Adult Cancer Survivors: A Systematic Review.

OBJECTIVES: This systematic review (PROSPERO CRD42021275421) synthesized evidence on the efficacy of cognitive rehabilitation on cognitive and functional outcomes in adult cancer survivors. METHODS: Articles were identified though PubMed/MEDLINE, EMBASE, PsycINFO, and Web of Science from inception through June 30, 2023. Studies included participants ≥18 years old, diagnosed with cancer. Primary outcomes were validated measures of subjective and objective cognition. Articles were dual reviewed for eligibility and data extraction. Risk of bias was assessed with the Standard Quality Assessment Criteria for Evaluating Primary Research Papers from a Variety of Fields. RESULTS: The search yielded 3,811 articles; 65 full-text articles were reviewed; 53 articles (15 cognitive training, 14 strategy-based, 21 combinations, three inpatient rehabilitation), representing 52 unique studies, were included. Positive effects were observed in at least one objective cognitive measure in 93% of strategy training, 81% of cognitive training, 79% of combination rehabilitation interventions. Positive effects were observed in subjective cognition in 100% of strategy training, 55% of cognitive training, and 92% of combination interventions. Among studies with comparator groups, processing speed improved in 60% of cognitive training studies, while strategy training did not improve processing speed; otherwise, cognitive domain effects were similar between intervention types. Impact on functional outcomes was inconclusive. CONCLUSIONS: Cognitive rehabilitation appear beneficial for cancer-related cognitive impairment (CRCI). Differential effects on specific cognitive domains (eg, processing speed) and subjective cognition may exist between intervention types. IMPLICATIONS FOR NURSING PRACTICE: Nurses should increase patient and provider awareness of the benefits of cognitive rehabilitation for CRCI.
