Assessing the Factor Structure and Measurement Invariance of the Pittsburgh Sleep Quality Index Between Postmenopausal Breast Cancer Survivors and Controls.

Background and Purpose: This study evaluates the Pittsburgh Sleep Quality Index (PSQI) in terms of factor structure and measurement invariance (MI). The sample included postmenopausal breast cancer (BC) survivors (n = 101) and matched healthy controls (n = 60). Methods: Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were performed on PSQI's seven component scores. MI was tested between groups and across time using Bayes factor (BF). Results: Two factors were identified: sleep efficiency and perceived sleep quality. MI is evidenced between groups (BF < 0.007) and over time (BF > 150). Conclusions: PSQI scores with two subscales are comparable between postmenopausal BC survivors and controls over a 1-year period, providing some validation of PSQI for researching sleep quality in this population.

Cancer-related cognitive impairment in older adults with acute myeloid leukemia treated with hypomethylating agents and venetoclax chemotherapy: a longitudinal descriptive study.

PURPOSE: To explore cancer-related cognitive impairment (CRCI) in older adults with acute myeloid leukemia (AML) receiving venetoclax in combination with hypomethylating agents or low-dose cytarabine chemotherapy. METHODS: This study is a longitudinal, qualitative descriptive study. Participants were recruited using purposive sampling. Semi-structured interviews were conducted among 11 older adults with AML at cycle 2, cycle 4, and cycle 7 of chemotherapy. An early end-of-study interview was conducted for those who changed treatment plans during the study follow-up. RESULTS: A total of 22 transcripts were included for thematic analysis. Four themes emerged: (1) CRCI experiences, (2) impact of CRCI, (3) CRCI coping strategies, and (4) perceived CRCI-related factors. Older adults with AML experienced challenges in memory, language, and attention both intermittently and daily. These cognitive changes impacted their emotion, daily activities, social connection, and their caregivers' responsibilities. Hence, these older adults with AML developed problem-solving and emotional coping strategies to cope with CRCI. Older adults with AML also identified demographic, physiology/clinical, psychological, and other factors that might contribute to CRCI. CONCLUSION: This study offers important insight for clinicians to understand how older adults with AML experience CRCI and how it impacts their daily routines. It indicates that clinicians should ask patients about their experience with cognitive changes at each encounter to provide support or coping strategies as needed to prevent CRCI from further hindering their quality of life.

DNA Methylation of BDNF and RASA2 Genes Is Associated With Cognitive Function in Postmenopausal Women With Breast Cancer.

OBJECTIVES: To determine associations among DNA methylation of brain-derived neurotrophic factor (BDNF) and RAS p21 protein activator 2 (RASA2) genes with processing speed and perceived cognitive function. SAMPLE & SETTING: This was a cross-sectional, secondary analysis of baseline data from a randomized controlled trial, the Exercise Program in Cancer and Cognition Study. METHODS & VARIABLES: Data included M values for DNA methylation of the BDNF and RASA2 genes; processing speed, objectively measured using the Grooved Pegboard and Digit Vigilance Test scores; and perceived cognitive function, self-reported using the Patient Assessment of Own Functioning Inventory. Regression analysis was conducted. RESULTS: Greater methylation of cg21291635 of the BDNF gene (p = 0.01) and cg20247102 of the RASA2 gene (p = 0.013) were associated with poorer processing speed, whereas greater methylation of cg20108357 of the BDNF gene (p < 0.001) and cg00567892 of the RASA2 gene (p = 0.019) were associated with better perceived cognitive function. IMPLICATIONS FOR NURSING: Gene methylation variations were demonstrated, suggesting the genes' potential roles and two possible distinct mechanisms of cognitive function in cancer. .

Association Between Genes in the Nuclear Factor E2-Related Factor 2 Antioxidative Response Elements Pathway and Cancer-Related Fatigue in Women With Early-Stage Breast Cancer.

OBJECTIVES: To explore genes in the nuclear factor E2-related factor 2 antioxidative response elements (Nrf2-ARE) signaling pathway using a multiomics approach for associations with variability of cancer-related fatigue (CRF) in postmenopausal women with early-stage hormone receptor-positive breast cancer. SAMPLE & SETTING: Postmenopausal women (N = 116) with early-stage hormone receptor-positive breast cancer were recruited from western Pennsylvania. METHODS & VARIABLES: Candidate genes from the Nrf2-ARE pathway were investigated for associations with CRF occurrence and severity. Associations were evaluated using logistic regression for occurrence and linear regression for severity. RESULTS: The rs2706110 TT genotype in NFE2L2 was associated with a 3.5-fold increase in odds of CRF occurrence. The cytosine-phosphate-guanine (CpG) site cg22820568 in PRDX1 was associated with CRF occurrence and severity. IMPLICATIONS FOR NURSING: Biomarkers based on Nrf2-ARE genes may help to identify women at increased risk for more severe CRF and to develop targeted interventions.

Effects of aerobic exercise on neurocognitive function in postmenopausal women receiving endocrine therapy for breast cancer: The Exercise Program in Cancer and Cognition randomized controlled trial.

Objective: The Exercise Program in Cancer and Cognition (EPICC) Study was a randomized controlled trial (RCT) designed to determine whether six months of moderate-intensity aerobic exercise improves neurocognitive function in women with breast cancer (BC) receiving endocrine therapy (ET). Methods: Postmenopausal women with hormone receptor+, early-stage BC, within two years post-primary therapy were randomized to the exercise intervention (six months, ≥150 minutes of moderate-intensity aerobic exercise/week) or usual care control condition. Outcomes were assessed at pre-randomization and after intervention completion. Groups were compared using linear mixed-effects modeling. Results: Participants (N=153) were X ¯ = 62.09 ± 8.27 years old, with stage I BC (64.1%) and a median of 4.7 months post-diagnosis. We found a group-by-time interaction (p=0.041) and a trend for the main effect of time (p=0.11) for processing speed with improved performance in the exercise group and no change in the controls. Similar main effects of time were observed for learning and memory (p=0.024) and working memory (p=0.01). Better intervention adherence was associated with improved processing speed (p=0.017). Conclusions: Six months of moderate-intensity aerobic exercise improves processing speed in postmenopausal women with BC receiving ET who initiate exercise within two years of completing primary therapy (surgery +/- chemotherapy). This is the first large-scale study to examine the effects of aerobic exercise on neurocognitive function in women with BC. Additional research is needed to address the long-term effects of aerobic exercise on cognitive function.

Dignity in people with dementia: A concept analysis.

Background: Dignity, an abstract and complex concept, is an essential part of humanity and an underlying guiding principle in healthcare. Previous literature indicates dignity is compromised in people with dementia (PwD), but those PwD maintain the capacity to live with dignity with appropriate external support. Alzheimer's disease and related dementias (ADRDs) lead to progressive functional decline and increased vulnerability and dependence, leading to heightened risks of PwD receiving inappropriate or insufficient care that diminishes dignity. Considering the increased disease prevalence and the continuously escalating costs of dementia care, establishing a productive value-based guideline may prevent suffering, maximize dignity, and thus promote quality of life (QoL).Aim: The goal of this project is to identify actionable targets for integrating dignity harmoniously and practically into care planning and management for PwD.Research Design: We conducted a concept analysis using Walker and Avant's eight-step process. A comprehensive literature search was conducted (PubMed and CINAHL) with the keywords "dignity," "dementia," "Alzheimer's disease," and "dementia care."Results: A total of 42 out of 4910 publications were included. The concept of dignity in PwD is operationalized as the promotion of worthiness and the accordance of respect that allows the presence and expression of a person's sense of self, regardless of physical, mental, or cognitive health. The concept has two subdimensions: absolute dignity which encompasses the inherent self and relative dignity characterized by its dynamic reflective nature. Worthiness and respect are the two main attributes, while autonomy is an underlying component of dignity. Specific antecedents of dignity in PwD are empowerment, non-maleficence, and adaptive environmental scaffolding. As a consequence of facilitating dignity in PwD, QoL may be enhanced.Conclusion: As a foundational and necessary humanistic value, incorporating dignity into dementia care can lead to efficient and effective care that optimizes QoL in PwD throughout their disease progression.

Preoperative cognitive function as a risk factor of postoperative delirium in cancer surgeries: A systematic review and meta-analysis.

Postoperative delirium (POD) after cancer surgeries can be a result of chemo brain, anesthesia, surgery duration, and preoperative cognitive impairment. Although older age and preoperative cognitive dysfunction were reported to increase the risk of POD in noncardiac surgery, the role of preoperative cognitive function and age in the development of POD after all types of cancer surgeries is not clear. This study aimed to determine the relationship between preoperative cognitive function and likelihood of POD after cancer surgeries. This study used three main online databases and followed PRISMA guidelines. English language original articles that examined preoperative cognitive function before solid tumor cancer surgery and assessed patients for postoperative delirium were included. We employed the random effect meta-analysis method. The overall incidence of POD ranged from 8.7% to 50.9%. The confusion assessment method was the most common tool used to assess delirium. Mini-mental state evaluation (MMSE), Mini-cog, and Montreal cognitive assessment were the most common tools to assess cognitive function. The pooled (total observation = 4676) random effects SMD was estimated at -0.84 (95% confidence interval [CI]: -1.30 to -0.31), indicating that lower MMSE scores before surgery are associated with a higher risk of POD. The pooled (total observation = 2668) random effects OR was estimated at 5.17 (95% CI: 2.51 to -10.63), indicating preoperative cognitive dysfunction can significantly predict the occurrence of POD after cancer surgeries. In conclusion, preoperative cognitive function is an independent and significant predictor of POD after solid tumor cancer surgeries.

Health-related quality of life over chemotherapy course among individuals with early-stage breast cancer: the association of social determinants of health and neighborhood socioeconomic disadvantage.

PURPOSE: This study aimed to examine relationships between health-related quality of life (HRQOL), social determinants of health, and neighborhood socioeconomic disadvantage in individuals with early-stage breast cancer (ESBC) during chemotherapy. METHODS: This is a longitudinal study that recruited Black and White women with ESBC receiving chemotherapy. Participants completed questionnaires recording their sociodemographic information at baseline and the Functional Assessment of Cancer Therapy-General (FACT-G) to report their HRQOL before each chemotherapy cycle. Linear mixed modeling was employed to examine the associations between FACT-G scores, self-reported race, and area deprivation index (ADI) before and at the last chemotherapy cycle, with the duration of chemotherapy treatment as a covariate. RESULTS: A total of 84 Black and 146 White women with ESBC completed the surveys. Linear mixed modeling results suggested that women with ESBC who reported being Black experienced significantly worse physical well-being than those who reported being White throughout chemotherapy, with a 0.22-point lower average (p = 0.02). Both Black and White women with ESBC experienced decreased functional well-being over the chemotherapy, and Black women consistently reported lower scores than White women, with the change in functional well-being over time differing between racial groups (p = 0.03). Participants' ADI national percentiles were not significantly associated with their HRQOL throughout chemotherapy. CONCLUSIONS: These findings underscore possible racial differences in some dimensions of HRQOL during chemotherapy among women with ESBC. Future research should consider further assessing life stressors and past experiences of discrimination and racism that may contribute to these disparities and guide proactive interventions.

Coverage for evidence-based cancer survivorship care services.

PURPOSE: The American Society of Clinical Oncology Cancer Survivorship Committee established a task force to determine which survivorship care services were being denied by public and private payers for coverage and reimbursement. METHODS: A quantitative survey instrument was developed to determine the clinical practice-reported rates of coverage denials for evidence-based cancer survivorship care services. Additionally, qualitative interviews were conducted to understand whether coverage denials were based on payer policies, cost-sharing, or prior authorization. RESULTS: Of 122 respondents from 50 states, respondents reported that coverage denials were common ("always," "most of the time," or "some of the time") for maintenance therapies, screening for new primary cancers or cancer recurrence. Respondents reported that denials in coverage for maintenance therapies were highest for immunotherapy (41.74%) and maintenance chemotherapy (40.17%). Coverage denials for new primary cancer screenings were highest for Hodgkin lymphoma survivors needing a PET/CT scan (49.04%) and breast cancer survivors at a high risk of recurrence who needed an MRI (63.46%), respectively. More than half of survey respondents reported denials for symptom management and supportive care services. Fertility services, dental services when indicated, and mental health services were denied "always" or "most of the time" 23.1%, 22.5%, and 12.8%, respectively. Respondents reported they often had a process in place to automatically appeal denials for evidence-based services. The denial process, however, resulted in greater stress for the patient and provider. CONCLUSION: Our study demonstrates that additional advocacy with payers is needed to ensure that reimbursement policies are consistent with evidence-based survivorship care services.

Economic Hardship and Associated Factors of Women With Early-Stage Breast Cancer Prior to Chemotherapy Initiation.

INTRODUCTION: Economic hardship (EH) can negatively influence cancer outcomes. Little is known about the factors that are associated with higher levels of EH among patients with breast cancer (BC). This paper describes EH in women with early-stage BC prior to or at their first chemotherapy treatment (baseline) and explores whether there are differences by race, area deprivation, stress, symptom distress, and social support. PATIENTS AND METHODS: A descriptive comparative/correlational design was employed using baseline data of a multisite, longitudinal, multimethod study comparing the symptom experience and management prior to prescribed chemotherapy for women with early-stage BC. Participants completed measures for EH, perceived stress, symptom distress, and social support. Race was measured by self-report. Area deprivation indices (ADI) measuring neighborhood economic factors were calculated from publicly available websites. RESULTS: Participants (N = 248; age = 52.9 ± 12.3 years) were 62% White and 38% Black, 54% partnered, and 98% insured. Compared to White patients, Black patients reported higher (worse) EH (1.2 ± 3.0 vs. -0.7 ± 2.4), lived in areas of greater deprivation (80.1 ± 2.1 vs. 50.5 ± 23.5),and were more likely to report inadequate household income (Black: 30.5%; White: 11.1%). Adjusting for race and age, being Black (P< .001), living in an area of greater deprivation (P = .049), higher perceived stress (P = .008), lower perceived appraisal (P = .040), and less tangible support (P < .001) contributed to greater EH. Worse symptom distress trended toward greater EH (P = .07). CONCLUSIONS: This study emphasizes the importance of incorporating baseline holistic assessment to identify patients most likely to experience EH during early-stage BC treatment.

The Effect of Race and Area Deprivation on Symptom Profiles over the Course of Early-Stage Breast Cancer.

Purpose: This study compared common symptoms (fatigue, pain), overall physical functioning and changes over time between Black and White women receiving early-stage breast cancer (ESBC) chemotherapy. Methods: A longitudinal, repeated measures comparative design was employed. Time points of symptom measurement (PROMIS domains) at baseline, mid and end point were adjusted as per patient chemotherapy schedule. Analyses: Linear mixed models were applied. Results: There were 147 patients, 36% Black 64% White (54±12 years) recommended to receive early-stage breast cancer chemotherapy with adequate data for symptom analysis. Pain: Main effect of race was significant (F(1, 390) = 29.43, p<.001) for pain with Black patients experiencing significantly higher pain scores compared to White patients at pretherapy (Mean Difference; MD=3.7, p=.034), midpoint (MD=5.8, p=.002), and endpoint (MD=7.8, p<.001). Fatigue: Fatigue significantly increased (deteriorated) at endpoint (MDT1-T3= 8.7, p<.001) for Black patients. Among White patients, fatigue significantly increased at midpoint (MDT1-T2= 5.7) and at endpoint (MDT1-T3=10.1, p<.001; MDT2-T3=4.3, p= .017). Physical function: Black patients had significantly lower physical function scores compared to White patients at midpoint (MD=4.0, p=.027). Physical function decreased by endpoint in Black (MDT1-T3=7.8, p<.001), and White patients (MDT1-T3=7.7, p<.001). Conclusion: Symptom burden significantly increased over the course of chemotherapy for all patients. Scores for pain and physical function were higher overall for Black patients and deteriorated at a greater rate for Black vs. White women over the course of chemotherapy. This assessment holds implication for proactive assessment and mitigation strategies.

Variability of DNA Repair and Oxidative Stress Genes Associated with Worst Pain in Breast Cancer Survivors on Aromatase Inhibitors.

Pain is a problem affecting women with breast cancer (HR+BrCa) receiving aromatase inhibitor (AI) therapy. We investigated the relationship between single-nucleotide polymorphisms (SNPs) in DNA repair and oxidative stress genes and perceived worst pain after 6 months of AI therapy. We explored 39 SNPs in genes involved in DNA repair (ERCC2, ERCC3, ERCC5, and PARP1) and oxidative stress (CAT, GPX1, SEPP1, SOD1, and SOD2) in women with HR+BrCa receiving adjuvant therapy (AI ± chemotherapy; n = 138). Pain was assessed via the Brief Pain Inventory. Hurdle regression was used to evaluate the relationship between each associated allele and (1) the probability of pain and (2) the severity of worst pain. ERCC2rs50872 and ERCC5rs11069498 were associated with the probability of pain and had a significant genetic risk score (GRS) model (p = 0.003). ERCC2rs50872, ERCC5rs11069498, ERCC5rs4771436, ERCC5rs4150360, PARP1rs3219058, and SEPP1rs230819 were associated with the severity of worst pain, with a significant GRS model (conditional mean estimate = 0.45; 95% CI = 0.29, 0.60; p < 0.001). These results suggest DNA repair and oxidative stress pathways may play a role in the probability of pain and the severity of worst pain. As healthcare delivery moves towards the model of precision healthcare, nurses may, in the future, be able to use these results to tailor patient care based on GRS.

Stakeholder perspectives on six identified interpersonal communication components of patient navigation in breast cancer care.

PURPOSE: Although identified as a key competency domain and a needed area of professional development, interpersonal communication in breast cancer care patient navigation is understudied. Moreover, the patient-navigator relationship may be influenced by the interpersonal communication skills and behaviors of the patient navigator. This paper reports on the interpretation step of a concept mapping study, where key stakeholders shared their perspectives on six identified interpersonal communication components of breast cancer care patient navigation. METHODS: This study utilized concept mapping, a community-engaged mixed method approach. After conducting brainstorming, sorting, and concept mapping analysis, a six-cluster concept map of interpersonal communication in breast cancer care patient navigation was identified. Interpretation sessions with each participant group (patients, patient navigators, administrators) allowed both naming and more in-depth exploration of the six clusters. The sessions were led by a facilitator, the PI, and were audio recorded and transcribed. RESULTS: Six 2-h interpretation sessions were conducted with 21 participants, including patients with breast cancer, breast cancer patient navigators (lay or medically trained), and patient navigation administrators from Western Pennsylvania. Through a group consensus process, the six clusters were named. Participants identified that all six identified components were essential to patient navigation, but the ability to build patient-centered trust and relationships and maintain professional communication were the most impactful components of the patient-navigator relationship. CONCLUSION: These findings validate the importance of interpersonal skills and behaviors of patient navigators in breast cancer care. These findings can inform the patient navigation role description, competencies, and the development of curriculum for training and metrics for evaluation.

Anaesthesia-related cognitive dysfunction following cardiothoracic surgery in late middle-age and younger adults: A scoping review.

AIM: This review aimed to evaluate factors associated with anaesthesia-related postoperative cognitive dysfunction (POCD) among adults younger than 65 years who underwent cardiothoracic surgeries. STUDY DESIGN: A systematic keyword search, following the scoping review framework, was performed in the PubMed and CINAHL databases. Original English-language studies that included adults younger than 65 years and addressed cognitive function after surgery along with anaesthesia management were included. Retrospective studies, animal research and in vitro and in vivo studies were excluded. RESULTS: Twenty-three articles were included (65.2% interventional studies). All studies lacked theoretical or conceptual frameworks. Ketamine's neuroprotective potential is questionable, and intravenous lidocaine may be considered a possible early agent for preventing POCD, but long-term effectiveness is uncertain. Compared to inhalational anaesthesia, total intravenous anaesthesia (TIVA) may be related to a decreased incidence of POCD. Variation in POCD assessment impacted the lack of homogeneity in obtained data. Moreover, the shorter-term timing of POCD evaluation such as in early days after surgery could be greatly influenced by medication and delirium. CONCLUSION: Although strategies such as TIVA, the use of neuroprotective anaesthetics and comprehensive preoperative assessments are suggested to prevent POCD, this multifactorial phenomenon cannot be explicitly attributed solely to anaesthetics or anaesthesia-related techniques. Use of standardized, reliable and valid tools for POCD assessment is encouraged for cross-study comparison. RELEVANCE TO CLINICAL PRACTICE: Nurses and certified nurse anaesthetists must be aware of risk factors for postoperative delirium and POCD so they can assess patients before and after surgery. Patients and caregivers need to be educated about cognitive changes after surgery and advised to report them to their health care provider if they occur.

Preferences on Delivery of Cancer Rehabilitation Services for Cancer-Related Disability Among Older Individuals Surviving Breast Cancer: A Qualitative Study.

Background: Older individuals surviving breast cancer often encounter cancer-related disability as a short-term or long-term effect of cancer and related treatment. Cancer rehabilitation interventions have the potential to prevent, mitigate, or remediate cancer-related disability. However, use of these services remains limited. Understanding the priorities and perspectives of older individuals surviving breast cancer is key to developing effective and implementable cancer rehabilitation interventions. This qualitative descriptive study examined individuals' preferred and valued methods of cancer rehabilitation intervention delivery. Methods: Using a qualitative descriptive design, older individuals surviving breast cancer (n=14) completed a single telephone-based semi-structure interview. Interviews explored survivors' preferences for cancer rehabilitation service delivery. Interview transcriptions were thematically analyzed. Open codes were inductively generated and reviewed for agreement by an independent reviewer. The codes were deductively organized. Differences were resolved through consensus meetings. Results: Findings revealed preferred intervention delivery characteristics for intervention setting, mode of delivery, format, and timing. Participants predominantly preferred interventions delivered in community-based settings, with both in-person and remote components. Participants also appeared to value one-on-one interventions and those delivered post-treatment. Survivors' overarching preferences were based on desire for patient-centric care, one-on-one therapist time, complex medical schedules, and financial concerns. Discussion: Study findings provide guidance on the modification of existing and creation of new cancer rehabilitation interventions addressing cancer-related disability in older individuals surviving breast cancer. Adoption of stakeholder-driven intervention delivery characteristics may improve value and acceptability of interventions. Future intervention research should incorporate and test these characteristics to ensure their effectiveness in real-world settings.

A Scoping Review on Work Experiences of Nurses After Being Diagnosed With Cancer.

PROBLEM IDENTIFICATION: To map key concepts underpinning work-related studies about nurses with cancer and identify knowledge gaps. LITERATURE REVIEW: A search was conducted in the PubMed®, CINAHL®, and PsycINFO® databases for articles about nurses with cancer and work-related topics published through March 2023. DATA EVALUATION: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews Checklist was used to report results, and the JBI critical appraisal tools were used to assess the quality of studies. Eleven articles were included. SYNTHESIS: The following four critical concepts were identified: role adjustments at work, cancer impacts on work, organizational support, and translating insights gained from cancer experience into work. Research gaps identified by the scoping review were a lack of theoretical or conceptual frameworks, lack of syntheses of main ideas, and lack of clear data about participants' socioeconomic status across studies. IMPLICATIONS FOR RESEARCH: Minimal research exists to map predictors, outcomes, or intervention targets to guide organizational strategies to support nurses' retention in the nursing workforce. A guiding framework, recruitment of diverse nurses, and focus on the four critical concepts identified in this scoping review are suggested for future research.

Psychoneurological symptom cluster trajectories in individuals treated for early-stage breast cancer.

BACKGROUND/PURPOSE: The psychoneurological (PN) symptom cluster has been defined in the literature as anxiety, depression, fatigue, sleep disturbance, and pain. PN symptoms are influenced by cancer and its treatment as well as biological and psychosocial factors. The purpose of this analysis was to describe temporal patterns of the PN symptom cluster severity in breast cancer survivors over the year following initial surgical intervention and investigate the time-dependent effect of treatment modality on symptom severity. METHODS: In a prospective longitudinal study, symptom data were collected from individuals with early-stage breast cancer 48 h after initial surgery and at monthly intervals for the subsequent 12 months using the PROMIS®-29 subscales for anxiety, depression, fatigue, sleep disturbance, and pain. Applying group-based trajectory modeling, we classified participants into subgroups with similar temporal patterns of PN symptom cluster severity and included treatment modality as a time-dependent covariate. RESULTS: Across 353 participants (mean age 60.10 ± 11.9 years, 88.95% white, 66.57% undergoing segmental mastectomies), four distinct trajectory subgroups (mild [47.6%; n = 168], moderate [28.3%; n = 100], severe [15.9%; n = 56], and most severe increasing [8.2%; n = 29]) were revealed for PN symptom cluster severity. Chemotherapy was associated with greater severity in all symptom severity subgroups, while radiation was associated with greater symptom severity in the mild and most severe increasing subgroups. CONCLUSIONS AND IMPLICATIONS: A subgroup of individuals with early-stage breast cancer experienced persistent severe PN symptoms. Future research should focus on psychosocial, biological, and disease-related characteristics of individuals in the most severe symptom group to inform preventative treatments and effective interventions.

Cardiorespiratory fitness is associated with hippocampal resting state connectivity in women newly diagnosed with breast cancer.

Background: Breast cancer and its treatment are associated with aberrant patterns of resting state functional connectivity (rsFC) between the hippocampus and several areas of the brain, which may account for poorer cognitive outcomes in patients. Higher cardiorespiratory fitness (CRF) has been associated with enhanced rsFC and cognitive performance; however, these associations have not been well studied in breast cancer. We examined the relationship between CRF, rsFC of the hippocampus, and cognitive performance among women newly diagnosed with breast cancer. Methods: Thirty-four postmenopausal women newly diagnosed with Stage 0-IIIa breast cancer (Mage = 63.59 ± 5.73) were enrolled in a 6-month randomized controlled trial of aerobic exercise vs. usual care. During baseline assessments, participants completed functional brain imaging, a submaximal CRF test, and cognitive testing. Whole-brain, seed-based analyses were used to examine the relationship between CRF and hippocampal rsFC, with age, years of education, and framewise displacement included as covariates. Cognition was measured with a battery of validated neurocognitive measures, reduced to seven composite factors. Results: Higher CRF was positively associated with greater rsFC of the hippocampus to a cluster within the dorsomedial and dorsolateral frontal cortex (z-max = 4.37, p = 0.003, cluster extent = 1,020 voxels). Connectivity within cluster peaks was not significantly related to cognitive factors (all ps > 0.05). Discussion: CRF was positively associated with hippocampal rsFC to frontal cortex structures, comprising a network of regions commonly suppressed in breast cancer. Future longitudinal research is needed to explore whether baseline rsFC predicts long-term cognitive resilience in breast cancer.

Genetic variability of oxidative stress and DNA repair genes associated with pre-treatment cancer-related fatigue in women with breast cancer.

PURPOSE: Investigate potential relationships between pre-treatment cancer-related fatigue (CRF) in women with early-stage breast cancer and variation in genes involved with oxidative stress and DNA repair. METHODS: Investigated 39 functional and tagging single nucleotide polymorphisms (SNPs) in genes involved in oxidative stress (CAT, GPX1, SEPP1, SOD1, and SOD2) and DNA repair (ERCC2, ERCC3, ERCC5, and PARP1) in a sample (N = 219) that included n = 138 postmenopausal women diagnosed with early-stage breast cancer before initiation of therapy and n = 81 age- and education-matched healthy controls. Using the Profile of Mood States Fatigue/Inertia Subscale, fatigue occurrence and severity were evaluated in both groups. Regression analysis was used to independently identify significant SNPs for three outcomes: 1) any fatigue versus no fatigue, 2) clinically meaningful versus non-clinically meaningful fatigue, and 3) fatigue severity. Using a weighted multi-SNP method, genetic risk scores (GRS) were calculated for each participant, and GRS models were constructed for each outcome. Models were adjusted for age, pain, and symptoms of depression and anxiety. RESULTS: SEPP1rs3877899, ERCC2rs238406, ERCC2rs238416, ERCC2rs3916874, and ERCC3rs2134794 were associated with fatigue occurrence and had a significant GRS model (OR = 1.317, 95%CI [1.067, 1.675], P ≤ 0.05). One SNP, SOD2rs5746136, was significant for clinically meaningful fatigue; therefore, a GRS model could not be constructed. ERCC3rs4150407, ERCC3rs4150477, and ERCC3rs2134794 were associated with fatigue severity with a significant GRS model (b = 1.010, 95%CI [1.647, 4.577], R2 = 6.9%, P ≤ 0.01). CONCLUSIONS: These results may contribute to identifying patients who are at risk of developing CRF. Oxidative stress and DNA repair biological pathways may be involved with CRF.

The feasibility, acceptability, and preliminary efficacy of a self-advocacy serious game for women with advanced breast or gynecologic cancer.

BACKGROUND: Cancer clinicians and systems aim to provide patient-centered care, but not all patients have the self-advocacy skills necessary to ensure their care reflects their needs and priorities. This study examines the feasibility, acceptability, and preliminary efficacy of a self-advocacy serious game (an educational video game) intervention in women with advanced breast or gynecologic cancer. METHODS: Women with recently diagnosed (<3 months) metastatic breast or advanced gynecologic cancer were randomized 2:1 to receive a tablet-based serious game (Strong Together) (n = 52) or enhanced care as usual (n = 26). Feasibility was based on recruitment, retention, data completion, and intervention engagement. Acceptability was assessed via a postintervention questionnaire and exit interview. Preliminary efficacy was assessed on the basis of change scores from baseline to 3 and 6 months in self-advocacy (Female Self-Advocacy in Cancer Survivorship Scale) using intention-to-treat analysis. RESULTS: Seventy-eight women (55.1% with breast cancer; 44.9% with gynecologic cancer) were enrolled. Feasibility was demonstrated by satisfactory recruitment (69% approach-to-consent rate; 93% enroll-to-randomize rate), retention (90% and 86% at 3 and 6 months, respectively; 85% data completion), and intervention engagement (84% completed ≥75% of the game). Participants endorsed the intervention's (75%) and trial's (87%) acceptability. Participants in the intervention group experienced significant improvements in self-advocacy at 3 and 6 months compared to participants in the control group. CONCLUSIONS: Strong Together is feasible and acceptable among women with advanced breast or gynecologic cancer. This intervention demonstrates promising evidence of clinical efficacy. A future confirmatory trial is warranted to test the efficacy of the intervention for patient and health system outcomes.
