Impact of Short-Term Creatine Supplementation on Muscular Performance among Breast Cancer Survivors.

Breast cancer (BC) is one of the most common cancers in the United States. Advances in detection and treatment have resulted in an increased survival rate, meaning an increasing population experiencing declines in muscle mass and strength. Creatine supplementation has consistently demonstrated improvements in strength and muscle performance in older adults, though these findings have not been extended to cancer populations. PURPOSE: The purpose of this study was to investigate the effects of short-term creatine supplementation on muscular performance in BC survivors. METHODS: Using a double-blind, placebo-controlled, randomized design, 19 female BC survivors (mean ± SD age = 57.63 ± 10.77 years) were assigned to creatine (SUPP) (n = 9) or dextrose placebo (PLA) (n = 10) groups. The participants completed two familiarization sessions, then two test sessions, each separated by 7 days, where the participants supplemented with 5 g of SUPP or PLA 4 times/day between sessions. The testing sessions included sit-to-stand power, isometric/isokinetic peak torque, and upper/lower body strength via 10 repetition maximum (10RM) tests. The interaction between supplement (SUPP vs. PLA) and time (Pre vs. Post) was examined using a group × time ANOVA and effect sizes. RESULTS: No significant effects were observed for sit-to-stand power (p = 0.471; ηp2 = 0.031), peak torque at 60°/second (p = 0.533; ηp2 = 0.023), peak torque at 120°/second (p = 0.944; ηp2 < 0.001), isometric peak torque (p = 0.905; ηp2 < 0.001), 10RM chest press (p = 0.407; ηp2 = 0.041), and 10RM leg extension (p = 0.932; ηp2 < 0.001). However, a large effect size for time occurred for the 10RM chest press (ηp2 = 0.531) and leg extension (ηp2 = 0.422). CONCLUSION: Seven days of creatine supplementation does not influence muscular performance among BC survivors.

Do beta-blockers reduce negative intrusive thoughts and anxiety in cancer survivors? - An emulated trial.

BACKGROUND: High rates of negative intrusive thoughts have been reported among cancer patients. Prevalent users of beta-blocker therapy have reported lower levels of cancer related intrusive thoughts than non-user. The aim of this study is to investigate if initiation of beta-blocker therapy reduces the prevalence and severity of intrusive thoughts (co-primary endpoints) and the prevalence of anxiety, depressed mood, and low quality of life (secondary endpoints) in cancer survivors. METHODS: Data on patient-reported outcomes from three cohort studies of Swedish patients diagnosed with colon, prostate or rectal cancer were combined with data on beta-blocker prescriptions retrieved from the Swedish Prescribed Drug Register. Two randomized controlled trials were emulated. Trial 1 had follow-up 1 year after diagnosis, trial 2 had follow-up 2 years after diagnosis, baseline in both trials was 12 months before follow-up. Those who initiated beta-blocker therapy between baseline and follow-up was assigned Active group, those who did not was assigned Control group. All endpoints were analysed using Bayesian ordered logistic regression. RESULTS: Trial 1 consisted of Active group, n = 59, and Control group, n = 3936. Trial 2 consisted of Active group, n = 87, and Control group, n = 3132. The majority of participants were men, 83% in trial 1 and 94% in trial 2. The prevalence and severity of intrusive thoughts were lower in the Active group in trial 1, but no significant differences between groups were found in either trial. The prevalence of depressed mood, worse quality of life and periods of anxiety were higher in the Active group in both trials with significant differences for quality of life in trial 1 and anxiety in trial 2. CONCLUSIONS: The emulated trials demonstrated no evidence of a protective effect of beta-blocker therapy against intrusive thoughts. The Active group had reduced quality of life and elevated anxiety compared to the Control group. TRIAL REGISTRATION: The three cohort studies were registered at isrctn.com/clinicaltrials.gov (ISRCTN06393679, NCT02530593 and NCT01477229).

'Only to reconcile with it'. The coping experience amongst middle-aged and older cancer survivors: A qualitative study.

BACKGROUND: Cancer threat is relevant to age, and the threat of a foreshortened life coupled with a lengthy treatment process negatively affects middle-aged and older adults. Understanding the coping throughout the cancer experience in middle-aged and older cancer survivors will help develop supportive care to promote their physiological and psychological coping effects. OBJECTIVES: To explore the cancer coping experiences of middle-aged adults aged 40-59 and older adults over 60. DESIGN: A descriptive phenomenological study was employed. METHODS: Face-to-face, in-depth, semistructured interviews were conducted with 22 oncology patients in a tertiary university hospital aged 40 or above from August to October 2023. The interview data were analyzed using thematic analysis procedures. RESULTS: Five themes and 13 subthemes were formed through analysis: acceptance of cancer (considering cancer as chronic, believing in fate and attributing cancer to karma); having different information needs (desired to be truthfully informed, information-seeking behaviour, information avoidance behaviour); getting families involved (developing dependent behaviours, feeling emotional support, family members suffering worse); striving to maintain positive psychological state (positive thinking, seeking peer support) and negative experience (undesirable, low self-esteem). CONCLUSION: Our study reveals that cancer survivors' attitudes towards having cancer have changed from a death sentence to a more positive perception of a chronic disease. Supportive programmes for developing coping strategies should consider the cultural traditions and religious beliefs, different information needs, involvement of family and promoting a positive psychological state while avoiding negative factors. PATIENT OR PUBLIC CONTRIBUTION: Participants with experience of coping with cancer were involved in the semistructured interview.

Factors Influencing Life Space Mobility in Cancer Survivors Following Hematopoietic Stem Cell Transplantation - Physical Function, Depression, Fatigue, Neighborhood Walkability, and Employment Status.

BACKGROUND/OBJECTIVE: The level of physical activity in the daily lives of cancer survivors following hematopoietic stem cell transplantation (HSCT) is crucial for maintaining their physical and mental health. Considering that life space mobility (LSM) may limit physical activity, maintaining and expanding LSM is particularly essential for post-HSCT survivors. This study aimed to identify factors influencing LSM in post-HSCT survivors. METHODS: Thirty cancer survivors after HSCT (14 women, mean age 52.0 ± 12.3 years, 196-3017 days post-HSCT) were included in this cross-sectional study. The assessment encompassed patient characteristics, employment status, life space (Life Space Assessment; LSA), physical function (handgrip strength, isometric knee extension strength, 5 chair standing test, walking speed), depression (Self-rating Depression Scale; SDS), fatigue (Cancer Fatigue Scale), and neighborhood walkability (Walk Score®). The association between LSA and each factor was compared by correlation analysis. Subsequently, multiple regression analysis was conducted, with LSA as the dependent variable and independent variables being outcome measures exhibiting a significant correlation with LSA. RESULTS: Variables significantly correlated with LSA included SDS (r =-0.65, p < .01), employment status (r=-0.60, p < .01), handgrip strength (r = 0.43, p = .02), and isometric knee extension strength (r = 0.40, p = .03). Results of multiple regression analysis show that SDS (ß = -0.53, p < .01), employment status (ß = 0.48, p < .01), and isometric knee extension strength (ß = 0.27, p = .02) were significantly associated with LSA (R2 = 0.74). CONCLUSION: Depression, employment status, and isometric knee extension strength were identified as factors related to LSM in post-HSCT survivors.

Ajuste y adaptación psicosocial de adultos jóvenes supervivientes de un cáncer en etapa pediátrica: Revisión sistemática / Psychosocial adjustment and adaptation in young adults surviving pediatric cancer: A systematic review

Introducción: Los efectos a largo plazo de tumores en la infancia pueden alterar la trayectoria de adaptación y ajuste psicosocial de los supervivientes en etapas de vida posteriores. Objetivo: Esta revisión sistemática se centra en analizar las experiencias de crecimiento postraumático, estrés postraumático, malestar emocional y dificultades psicosociales sufridas por jóvenes adultos supervivientes a un cáncer en etapa pediátrica. Resultados: Los resultados sugieren una trayectoria mayoritaria que podría definirse como adaptativa, en la que se observa tanto crecimiento postraumático (prevalencia superior al 60%), como síntomas de estrés postraumático (prevalencia inferior al 30%). No obstante, en comparación con población control no oncológica, estos supervivientes tienen mayor riesgo de padecer síntomas de ansiedad y depresión, de alcanzar menores logros educativos y profesionales, y de permanecer solteros o vivir solos, lo que se hipotetiza que podría estar relacionado con las secuelas de cada tipo de tumor y tratamiento, y no únicamente con la vivencia de la enfermedad. Conclusiones: La atención a jóvenes adultos supervivientes a un cáncer pediátrico debería centrarse en proporcionar mayor apoyo médico y psicosocial a largo plazo, a través del abordaje interdisciplinar y la atención centrada en la persona, como aproximación que favorezca una trayectoria de ajuste adaptativa.(AU)

Introduction: Long-term effects of childhood tumors can alter the trajectory of adjustment and psychosocial adjustment of survivors later in life. Purpose: This systematic review focuses on analyzing the experiences of posttraumatic growth, posttraumatic stress, emotional distress, and psychosocial difficulties experienced by young adult survivors of pediatric cancer. Results: The results suggest a more prevalent trajectory that could be conceptualize as adaptive, in which both post-traumatic growth (prevalence greater than 50%) and post-traumatic stress symptoms (prevalence less than 30%) are observed. However, compared to the non-oncology control population, these survivors are at higher risk for anxiety and depressive symptoms, lower educational and occupational attainment, and remaining single or living alone, which is hypothesized to be related to the sequelae of each tumor type and treatment, and not just the disease experience. Conclusions: Care for young adult survivors of pediatric cancer should focus on providing enhanced long-term medical and psychosocial support through an interdisciplinary approach and person-centered care as an approach that supports a trajectory of adaptive adjustment.(AU)

Preliminary testing of "roadmap to parenthood" decision aid and planning tool for family building after cancer: Results of a single-arm pilot study.

OBJECTIVE: Many young adult female cancer survivors need to use reproductive medicine, surrogacy, or adoption to have a child. This study pilot tested Roadmap to Parenthood, a web-based, self-guided decision aid and planning tool for family building after cancer (disease agnostic). METHODS: A single-arm pilot study tested feasibility, acceptability, and obtained effect size estimates of the Roadmap tool. Participants, recruited via hospital-based and social media strategies, completed a baseline survey (T1), accessed the Roadmap tool (website), then completed surveys at one- and 3-months (T2 and T3, respectively). Feasibility and acceptability were evaluated with rates of eligibility, enrollment, and survey completion, and feedback. Pairwise t-tests and repeated measures ANOVA evaluated usage effects. Effect size estimates were calculated. RESULTS: Participants (N = 98) averaged 31 years old (SD = 5.61); 71% were nulliparous. Enrollment rate was 73%, T1-T2 completion rate was 80%, and 93% accessed the website. From T1-T2, participants reported improvements in decisional conflict (p < 0.001; Cohen's d = 0.85), unmet information needs (p < 0.001; Cohen's d = 0.70), self-efficacy (p = 0.003; Cohen's d = 0.40), and self-efficacy for managing negative emotions (p = 0.03; Cohen's d = 0.29); effects were sustained at T3. There was no change in reproductive distress (p = 0.22). By T3, 94% reported increased consideration of preparatory actions and 20%-61% completed such actions. CONCLUSIONS: The Roadmap intervention was feasible to conduct, acceptable to users, and led to improvements in key psychosocial outcomes. Future directions will test intervention efficacy in a randomized controlled trial with a larger sample and over a longer period. A web-based tool may help women make decisions about family building after cancer and prepare for potential challenges.

Functional quality of life among newly diagnosed young adult colorectal cancer survivors compared to older adults: results from the ColoCare Study.

PURPOSE: Colorectal cancer (CRC) incidence and mortality are increasing among young adults (YAs) aged 18-39. This study compared quality of life (QOL) between YA and older adult CRC survivors in the ColoCare Study. METHODS: Participants were grouped by age (years) as follows: 18-39 (YA), 40-49, 50-64, and 65 + . Functional QOL (physical, social, role, emotional, cognitive) and global QOL were assessed with the EORTC-QLQ-C30 at enrollment, 3, 6, and 12 months. Average scores were compared between groups over time using longitudinal mixed-effect modeling. Proportions with clinically meaningful QOL impairment were calculated using age-relevant thresholds and compared between groups over time using logistic regression with mixed effects. RESULTS: Participants (N = 1590) were n = 81 YAs, n = 196 aged 40-49, n = 627 aged 50-64, and n = 686 aged 65 + . Average physical function was better among YAs than participants aged 50-64 (p = 0.010) and 65 + (p < 0.001), and average social function was worse among YAs than aged 65 + (p = 0.046). Relative to YAs, all age groups were less likely to report clinically meaningful social dysfunction (aged 40-49 OR = 0.13, 95%CI = 0.06-0.29; aged 50-64 OR = 0.10, 95%CI = 0.05-0.21; aged 65 + OR = 0.07, 95%CI = 0.04-0.15) and role dysfunction (aged 40-49 OR = 0.36, 95%CI = 0.18-0.75; aged 50-64 OR = 0.41, 95%CI = 0.22-0.78; aged 65 + OR = 0.32, 95%CI = 0.17-0.61). Participants aged 40-49 were also less likely to report physical dysfunction (OR = 0.42, 95%CI = 0.19-0.93). CONCLUSION: YA CRC survivors reported better physical and worse social function compared to older CRC survivors, and YA CRC survivors were more likely to report clinically meaningful social, role, and physical disfunction. Future work should further investigate QOL using age-relevant benchmarks to inform best practices for CRC survivorship care. TRIAL REGISTRATION: NCT02328677, registered December 2014.

Cancer survivorship in urban people living with cancer following primary treatment: A secondary analysis of qualitative interview data.

PURPOSE: Urban cancer survivors have been shown to have better opportunities for recovery of health and wellbeing than their rural counterparts. Whilst there is a considerable body of evidence that explores urban people with cancers' experiences and outcomes, there is a dearth of research that explicitly explores 'urban cancer survivorship' in its own right. This study aimed to explore cancer survivorship in urban people living with cancer who have completed primary treatment. METHODS: Secondary analysis of in-depth interview data (n = 18) with adults living with cancer who resided in urban parts of the UK. Data were drawn from a broader study on self-management of people living with cancer. An adapted version of Foster and Fenlon's recovery of health and wellbeing in cancer survivorship framework was used to inform the analysis of the data. RESULTS: Recovery of health and wellbeing was impacted by a variety of contributory factors, which had a largely positive impact. Access to amenities, social support, travel, and healthcare factors were opportunities for urban cancer survivors, whilst pollution, traffic and a lack of green spaces acted as challenges for health management. CONCLUSION: This study demonstrated how urban residency acted as both a barrier and a facilitator to recovery of health and wellbeing in urban cancer survivors following the completion of primary treatment. Area of residence should be taken into account by health providers and policymakers supporting cancer survivorship and the views of those with lived experiences should be included in informing future practice.

Evaluating the Usability of an mHealth App for Empowering Cancer Survivors With Disabilities: Heuristic Evaluation and Usability Testing.

BACKGROUND: More than 18 million cancer survivors are living in the United States. The effects of cancer and its treatments can have cognitive, psychological, physical, and social consequences that many survivors find incredibly disabling. Posttreatment support is often unavailable or underused, especially for survivors living with disabilities. This leaves them to deal with new obstacles and struggles on their own, oftentimes feeling lost during this transition. Mobile health (mHealth) interventions have been shown to effectively aid cancer survivors in dealing with many of the aftereffects of cancer and its treatments; these interventions hold immense potential for survivors living with disabilities. We developed a prototype for WeCanManage, an mHealth-delivered self-management intervention to empower cancer survivors living with disabilities through problem-solving, mindfulness, and self-advocacy training. OBJECTIVE: Our study conducted a heuristic evaluation of the WeCanManage high-fidelity prototype and assessed its usability among cancer survivors with known disabilities. METHODS: We evaluated the prototype using Nielsen's 10 principles of heuristic evaluation with 22 human-computer interaction university students. On the basis of the heuristic evaluation findings, we modified the prototype and conducted usability testing on 10 cancer survivors with a variety of known disabilities, examining effectiveness, efficiency, usability, and satisfaction, including a completion of the modified System Usability Scale (SUS). RESULTS: The findings from the heuristic evaluation were mostly favorable, highlighting the need for a help guide, addressing accessibility concerns, and enhancing the navigation experience. After usability testing, the average SUS score was 81, indicating a good-excellent design. The participants in the usability testing sample expressed positive reactions toward the app's design, educational content and videos, and the available means of connecting with others. They identified areas for improvement, such as improving accessibility, simplifying navigation within the community forums, and providing a more convenient method to access the help guide. CONCLUSIONS: Overall, usability testing showed positive results for the design of WeCanManage. The course content and features helped participants feel heard, understood, and less alone.

Diet quality and cardiovascular disease risk among breast cancer survivors in the Pathways Study.

BACKGROUND: Women with breast cancer are at higher risk of cardiovascular disease (CVD) compared with women without breast cancer. Whether higher diet quality at breast cancer diagnosis lowers this risk remains unknown. We set out to determine if higher diet quality at breast cancer diagnosis was related to lower risk of CVD and CVD-related death. METHODS: This analysis included 3415 participants from the Pathway Study, a prospective cohort of women diagnosed with invasive breast cancer at Kaiser Permanente Northern California between 2005 and 2013 and followed through December 31, 2021. Scores from 5 diet quality indices consistent with healthy eating were obtained at the time of breast cancer diagnosis. Scores were categorized into ascending quartiles of concordance for each diet quality index, and multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated. P values were 2-sided. RESULTS: The Dietary Approaches to Stop Hypertension diet quality index was associated with lower risk of heart failure (HR = 0.53, 95% CI = 0.33 to 0.87; Ptrend = .03), arrhythmia (HR = 0.77, 95% CI = 0.62 to 0.94; Ptrend = .008), cardiac arrest (HR = 0.77, 95% CI = 0.61 to 0.96; Ptrend = .02), valvular heart disease (HR = 0.79, 95% CI = 0.64 to 0.98; Ptrend = .046), venous thromboembolic disease (HR = 0.75, 95% CI = 0.60 to 0.93; Ptrend = .01), and CVD-related death (HR = 0.70, 95% CI = 0.50 to 0.99; Ptrend = .04), when comparing the highest with lowest quartiles. Inverse associations were also found between the healthy plant-based dietary index and heart failure (HR = 0.60, 95% CI = 0.39 to 0.94; Ptrend = .02), as well as the alternate Mediterranean dietary index and arrhythmia (HR = 0.74, 95% CI = 0.60 to 0.93; Ptrend = .02). CONCLUSION: Among newly diagnosed breast cancer patients, higher diet quality at diagnosis was associated with lower risk of CVD events and death.

Knowledge and attitude on childhood cancer survivorship among healthcare trainees: a multicentre study from India.

BACKGROUND: The proportion of childhood cancer survivors (CCS) in low/middle-income countries (LMICs) is rising. CCS often develop several physical and psycho-social long-term adverse effects, with unique healthcare needs. Primary healthcare providers (primary care physicians (PCPs)), especially in LMICs, are often not equipped to handle survivorship care. This study aimed to assess knowledge, and attitude among trainee healthcare providers concerning major issues of paediatric survivorship care. METHODS: A multi-centre, cross-sectional, questionnaire-based study was conducted among nursing and medical undergraduate students, and postgraduate medical residents across three tertiary-care teaching hospitals in India-All India Institute of Medical Sciences, New Delhi; Jawaharlal Institute of Postgraduate Medical Education and Research, Puducherry; and Maulana Azad Medical College, New Delhi. A questionnaire with total of 24 questions (14 knowledge-based and 10 attitude-based) was finalised after validation by expert review and piloting. The major domains covered in the questionnaire included knowledge and attitude regarding long-term adverse effects and psychosocial, employment-related issues faced by the survivors. It was administered to the study participants electronically. The knowledge-based questions had true/false responses (scored as 0 or 1 if incorrect or correct, respectively). Attitude-based questions were scored as 5-point Likert scale. RESULTS: Total 898 responses were collected (median age: 21 years, 64% (576/898) female). Among the respondents, 44% were undergraduate medical students, 42% were nursing students and 14% were postgraduate medical residents. The mean (SD) of knowledge score was 8.72 (2.04) (out of 14). On multivariable analysis, only discipline of training predicted knowledge scores regarding survivorship care. Postgraduate medical residents (9.08) as well as undergraduate medical students (8.85), had significantly higher mean knowledge scores than nursing students (8.47) (p=0.004).Two questions were answered incorrectly by the majority; children and siblings of CCS need additional genetic screening (79% incorrectly answered true), and CCS face intimacy issues in relation to normal sexual functioning (59% incorrectly answered false).Nearly half (48%) of respondents believed that their knowledge of cancer survivorship issues was inadequate. Majority of respondents (84%) suggested that oncologists should handle long-term survivorship care rather than PCPs. CONCLUSION: Trainee healthcare providers in India reported inadequate knowledge regarding survivorship care. Improving awareness by incorporating survivorship in teaching curriculum is imperative to equip future PCPs to provide survivorship care across the country.

Weight Changes in Breast Cancer Survivors in a Nigerian Hospital: Pattern and Correlates.

BACKGROUND: One of the recognized issues faced by cancer survivors is increasing weight. Weight gain has been associated with an increased death rate in cancer survivors. Research on weight gain among breast cancer survivors (BCS) is scarce in Nigeria. AIM: To assess the weight changes and its associated factors in breast cancer survivors (BCS). MATERIALS AND METHODS: A total of 98 breast cancer survivors attending the Radiation Oncology clinic were recruited. Sociodemographic variables, treatment history, weight at presentation, and present weight were obtained. Patients were then categorized into three groups: weight gain (>5% increase), stable weight (-5 to 5% change), or weight loss (>5% decrease). RESULT: The present mean weight and BMI were significantly higher than at presentation (75.14±17.59 kg vs 76.88±17.42 kg, p=< 0.0001) and (28.74 ± 6.30 vs 29.42 ±6.20, < 0.0001) respectively. Only 28 (29.6%) gained weight, 65 (66.3%) maintained stable weight while 5 (5.1%) lost weight. On univariate analysis, older age, living with partners, presence of comorbidity, year of last chemotherapy less than one year, and hormonal therapy use were associated with weight gain. Multivariate analysis revealed that the presence of comorbidities, patients receiving the last chemotherapy less than a year from the time of recruitment, and hormonal therapy were independently associated with weight gain. CONCLUSION: About a quarter of BCS gained weight. Older age, presence of comorbidity, year of last chemotherapy less than one year, and hormonal therapy use were associated with weight gain. The weight of cancer survivors should be monitored regularly during follow-up visits.

CONTEXTE: L'une des problématiques reconnues rencontrées par les survivantes du cancer est la prise de poids croissante. La prise de poids a été associée à un taux de mortalité accru chez les survivantes du cancer. La recherche sur la prise de poids parmi les survivantes du cancer du sein (SCS) est rare au Nigeria. OBJECTIF: Évaluer les changements de poids et leurs facteurs associés chez les survivantes du cancer du sein (SCS). MATÉRIAUX ET MÉTHODES: Au total, 98 survivantes du cancer du sein fréquentant la clinique d'oncologie radiationnelle ont été recrutées. Les variables sociodémographiques, l'historique des traitements, le poids à la présentation et le poids actuel ont été obtenus. Les patients ont ensuite été répartis en trois groupes : prise de poids (augmentation >5 %), poids stable (changement de -5 à 5 %) ou perte de poids (diminution >5 %). RÉSULTAT: La moyenne actuelle du poids et de l'IMC étaient significativement plus élevés qu'à la présentation (75,14 ± 17,59 kg contre 76,88 ± 17,42 kg, p < 0,0001) et (28,74 ± 6,30 contre 29,42 ± 6,20, p < 0,0001) respectivement. Seuls 28 (29,57%) ont pris du poids, 65 (66,3%) ont maintenu un poids stable tandis que 5 (5,1%) ont perdu du poids. À l'analyse univariée, l'âge plus avancé, la cohabitation avec un partenaire, la présence de comorbidité, l'année de la dernière chimiothérapie de moins d'un an et l'utilisation de thérapie hormonale étaient associées à une prise de poids. L'analyse multivariée a révélé que la présence de comorbidités, les patientes ayant reçu la dernière chimiothérapie moins d'un an avant le recrutement et la thérapie hormonale étaient indépendamment associées à une prise de poids. CONCLUSION: Environ un quart des survivantes du cancer du sein ont pris du poids. Le poids supplémentaire était associé à un âge plus avancé, à la présence de comorbidités, à la réception de la dernière chimiothérapie moins d'un an auparavant et à l'utilisation d'une thérapie hormonale. Il est donc recommandé de surveiller régulièrement le poids des survivantes du cancer lors des visites de suivi. Cela permettrait d'identifier les changements de poids précocement et de mettre en place des interventions appropriées pour prévenir une prise de poids excessive et ses conséquences néfastes sur la santé des survivantes du cancer. MOTS CLÉS: Changements de poids, Survivantes du cancer du sein, Corrélations.

Psychometric validation of the 15-item Patient Health Questionnaire - Anxiety and Depression Scale (PHQ-ADS) to assess psychological distress in breast cancer survivors.

OBJECTIVE: Psychological distress persists amongst breast cancer survivors, so reliable assessment of symptoms is essential. The Patient Health Questionnaire Anxiety and Depression Scale (PHQ-ADS) is a composite measure of depression and anxiety and has been used to measure distress. This study aimed to evaluate the psychometric properties of the PHQ-ADS within breast cancer survivors. METHOD: Breast cancer survivors (N = 280) were recruited online and followed up at 12-months. Depression (PHQ-8) and anxiety (GAD-7) items formed the composite PHQ-ADS score. Additional measures included: distress thermometer (convergent validity), fear of cancer recurrence and COVID distress (discriminant validity), and self-compassion (predictive validity). Confirmatory factor analysis (CFA) using weighted least squares mean and variance adjusted estimation was undertaken. RESULTS: One, two, and bifactor models underlying the PHQ-ADS were evaluated. The bifactor model had the most appropriate model fit overall. Omega hierarchical for the general distress factor was 0.914, accounting for 82% of explained variance. This suggests the PHQ-ADS is sufficiently unidimensional to warrant use of a total composite score. The PHQ-ADS demonstrated strong convergent and moderate discriminant validity. Self-compassion was an independent predictor of distress at 12-months. CONCLUSIONS: The PHQ-ADS is a valid measure for psychological distress in breast cancer survivors prescribed hormone therapy.

Impact of risk factors, early rehabilitation and management of lymphedema associated with breast cancer: a retrospective study of breast Cancer survivors over 5 years.

BACKGROUND: Breast cancer-related lymphedema (BCRL) is a potentially disabling and often irreversible consequence of breast cancer treatment, caused by the mechanical incompetence of the lymphatic system, resulting in reduced drainage capacity and functional overload due to an excessive volume of interstitial fluid surpassing the system's transport capacity in the arm. We wanted to determine the impact and explore the differences in independent risk factors for the occurrence of BCRL; incidence of BCRL over a five-year period at the Institute of Oncology Vojvodina in Sremska Kamenica and to answer the research question regarding the influence of the prehabilitation program on the overall incidence of BCRL during the observed five-year period. METHODS: From 2014 to 2018, a retrospective study was conducted at the Institute of Oncology of Vojvodina in Sremska Kamenica, analyzing female patients who had undergone breast cancer surgery. RESULTS: The study included 150 breast cancer patients who developed secondary lymphedema following surgery with the mean age of 59.2 ± 11.3 years. Fluctuations in hospitalization rates were observed over the five-year period, with the highest number of admissions in 2014 (24.0%) and a decline in 2018 (14.0%). The most common surgical procedure performed was left quadrantectomy (24.0%), followed by right quadrantectomy (20.0%) and left amputation (15.3%). The mean number of removed lymph nodes was 15.2 ± 6.1, with no statistically significant association between the number of removed lymph nodes and the manifestation of secondary lymphedema. The severity of secondary lymphedema varied based on patient age, with a higher incidence of moderate and severe lymphedema observed in patients aged 61 years and older. Patients who underwent radical surgery were more likely to experience severe lymphedema compared to those who had conservative surgery, although this difference was not statistically significant. CONCLUSION: In our study, the type of surgery, elapsed time since surgery, and the number of removed lymph nodes were not influencing factors for the occurrence of BCRL. However, concerning its severity, a greater number of systemic therapy modalities combined with radiotherapy were associated with a more frequent occurrence of mild and moderate BCRL. Also, the severity of BCRL varied among different age groups, with a higher incidence of moderate and severe lymphedema observed in patients aged 61 years and older. Ultimately, improving the quality of life for individuals affected by secondary lymphedema remains a crucial goal in the field of oncology.

Contextual Factors Relevant to Implementing Social Risk Factor Screening and Referrals in Cancer Survivorship: A Qualitative Study.

Introduction: Social risk factors such as food insecurity and lack of transportation can negatively affect health outcomes, yet implementation of screening and referral for social risk factors is limited in medical settings, particularly in cancer survivorship. Methods: We conducted 18 qualitative, semistructured interviews among oncology teams in 3 health systems in Washington, DC, during February and March 2022. We applied the Exploration, Preparation, Implementation, Sustainment Framework to develop a deductive codebook, performed thematic analysis on the interview transcripts, and summarized our results descriptively. Results: Health systems varied in clinical and support staff roles and capacity. None of the participating clinics had an electronic health record (EHR)-based process for identifying patients who completed their cancer treatment ("survivors") or a standardized cancer survivorship program. Their capacities also differed for documenting social risk factors and referrals in the EHR. Interviewees expressed awareness of the prevalence and effect of social risk factors on cancer survivors, but none employed a systematic process for identifying and addressing social risk factors. Recommendations for increasing screening for social risk factors included designating a person to fulfill this role, improving data tracking tools in the EHR, and creating systems to maintain up-to-date information and contacts for community-based organizations. Conclusion: The complexity of cancer care workflows and lack of reimbursement results in a limited ability for clinic staff members to screen and make referrals for social risk factors. Creating clinical workflows that are flexible and tailored to staffing realities may contribute to successful implementation of a screening and referral program. Improving ongoing communication with community-based organizations to address needs was deemed important by interviewees.

Correlates of physical activity and sedentary behavior among cancer survivors and cancer-free women: The Women's Health Accelerometry Collaboration.

BACKGROUND: Describing correlates of physical activity (PA) and sedentary behavior (SB) among postmenopausal cancer survivors can help identify risk profiles and can be used to support development of targeted interventions to improve PA and reduce SB in this population. OBJECTIVE: To describe PA/SB and identify correlates of PA/SB among cancer and cancer-free post-menopausal women. METHODS: Women from the Women's Health Study (N = 16,629) and Women's Health Initiative/Objective Physical Activity and Cardiovascular Health Study (N = 6,079) were asked to wear an accelerometer on the hip for 7 days. Multiple mixed-effects linear regression models were used to identify sociodemographic-, health-, and chronic condition-related correlates (independent variables) associated with PA and SB (dependent variables) among women with (n = 2,554) and without (n = 20,154) a history of cancer. All correlates were mutually adjusted for each other. RESULTS: In unadjusted analyses, women with a history of cancer took fewer mean daily steps (4,572 (standard deviation 2557) vs 5,029 (2679) steps/day) and had lower mean moderate-to-vigorous PA (74.9 (45.0) vs. 81.6 (46.7) minutes/day) than cancer-free women. In adjusted analyses, for cancer and cancer-free women, age, diabetes, overweight, and obesity were inversely associated with all metrics of PA (average vector magnitude, time in moderate-to-vigorous PA, step volume, time at ≥40 steps/minutes, and peak 30-minute step cadence). In unadjusted analyses, mean SB was similar for those with and without cancer (529.7 (98.1) vs. 521.7 (101.2) minutes/day). In adjusted analyses, for cancer and cancer-free women, age, diabetes, cardiovascular disease, current smoking, overweight, and obesity were positive correlates of SB, while Black or Hispanic race/ethnicity, weekly/daily alcohol intake, and excellent/very good/good self-rated health were inverse correlates of SB. CONCLUSION: Several sociodemographic, health, and chronic conditions were correlates of PA/SB for postmenopausal women with and without cancer. Future studies should examine longitudinal relationships to gain insight into potential determinants of PA/SB.

The Impact of Chemotherapy-Related Cognitive Impairment on Social Roles and Well-Being in Breast Cancer Survivors.

PURPOSE: To explore the impact of disruptions in information processing (DIPs) on social roles, well-being, and quality of life (QOL) in breast cancer survivors after chemotherapy. PARTICIPANTS & SETTING: Experiences of DIPs were explored in eight breast cancer survivors aged 53-70 years, 12-60 months post-treatment, referred from a National Cancer Institute-designated cancer center and a nonprofit breast cancer support organization from January 6 to August 31, 2020. METHODOLOGIC APPROACH: This study used a mixed-methods approach. Participants journaled and answered questionnaires sent via mail that asked them about changes in their cognition, QOL, and social roles. Qualitative data were thematically analyzed using constant comparative analysis, and questionnaire scores were compared with qualitative data. FINDINGS: Journals revealed problems with functioning in occupational roles and increased stress, anxiety, and frustration. Women with more DIPs tended to have lower role satisfaction and QOL. Greater role satisfaction was associated with higher QOL and social role participation. IMPLICATIONS FOR NURSING: Mitigating the effects of DIPs on social function may allow women to continue in important roles, which has the potential to affect QOL.

Effect of exercise based interventions on sleep and circadian rhythm in cancer survivors-a systematic review and meta-analysis.

Background: Disrupted circadian rhythm commonly reported in cancer survivors is closely associated with cancer related fatigue, sleep disturbances and compromised quality of life. As more cancer survivors request non-pharmacological treatment strategies for the management of their chronic sleep-related symptoms, there is a need for meta-analyses of various interventions such as exercise on sleep and circadian rhythm disturbances. Methods: A search for RCT's was conducted in April 2020 and updated in July 2023 using relevant keywords for cancer, sleep, circadian rhythm and exercise interventions on PubMed, Scopus, Web of Science, PEDro and CINAHL. Results: Thirty-six studies were included for qualitative analysis and 26, for meta-analysis. Thirty-five studies analyzed sleep outcomes, while five analyzed circadian rhythm. RCT's studying the effect of aerobic exercise, resistance exercise, combined aerobic and resistance exercise, physical activity, yoga, or tai chi were included. Meta-analysis results showed significant exercise-related improvements on sleep quality assessed by Pittsburgh Sleep Quality index (PSQI) (SMD = -0.50 [-0.87, -0.13], p = 0.008), wake after sleep onset (WASO) (SMD = -0.29 [-0.53, -0.05], p = 0.02) and circadian rhythm, assessed by salivary cortisol levels (MD = -0.09 (95% CI [-0.13 to -0.06]) mg/dL, p < 0.001). Results of the meta-analysis indicated that exercise had no significant effect on sleep efficiency, sleep onset latency, total sleep time and circadian rhythm assessed by accelerometry values. Conclusion: While some sleep and circadian rhythm outcomes (PSQI, WASO and salivary cortisol) exhibited significant improvements, it is still somewhat unclear what exercise prescriptions would optimize different sleep and circadian rhythm outcomes across a variety of groups of cancer survivors. Implication: As exercise does not exacerbate cancer-related circadian rhythm and sleep disturbances, and may actually produce some significant benefits, this meta-analysis provides further evidence for cancer survivors to perform regular exercise.

Association of race/ethnicity and patient care experiences with healthcare utilization and healthcare costs among prostate cancer survivors: A SEER-CAHPS study.

INTRODUCTION: This study aimed to evaluate the association of race/ethnicity and patient care experiences (PCEs) with healthcare utilization and costs among US older adults with prostate cancer (PCa). MATERIALS AND METHODS: The study used data from 2007 to 2015 Surveillance, Epidemiology, and End Results dataset linked to Medicare Consumer Assessment of Healthcare Providers and Systems survey and Medicare claims (SEER-CAHPS). We identified males aged ≥65 years who completed a CAHPS survey within 6-60 months post-PCa diagnosis. Covariate-adjusted associations of six CAHPS PCE composite measures with any emergency department visit and any inpatient stay (using logistic regressions), and with total part A and part B Medicare costs (using generalized linear models) were examined by race/ethnicity (non-Hispanic White, non-Hispanic Black, Hispanic, non-Hispanic Asian, and other). RESULTS: Among 1834 PCa survivors, a 1-point higher score for getting care quickly was associated with higher odds (odds ratio 1.08; 95% confidence interval [CI]: 1.02-1.15; p = 0.009) of any inpatient stay in Hispanic patients. Higher total costs were associated with a 1-point higher score for getting needed care among Hispanic patients ($590.84; 95% CI: $262.15, $919.53; p < 0.001); a 1-point higher score for getting care quickly among Hispanic patients ($405.26; 95% CI: $215.83, $594.69; p < 0.001); and a 1-point higher score for customer service among patients belonging to other races ($361.69; 95% CI: $15.68, $707.69; p = 0.04). DISCUSSION: We observed differential associations by race/ethnicity between PCEs and healthcare utilization and costs. Further research is needed to explore the causes of these associations.

Quality of working life and adaptability of returning to work in nurse cancer survivors: a cross-sectional study.

OBJECTIVE: To explore the relationship between quality of working life (QWL) and adaptability of returning to work (RTW) among nurse cancer survivors (NCSs). METHOD: We conducted a cross-sectional study on nurses previously diagnosed with cancer. QWL was quantified using the Quality of Working Life Scale (QWL7-32), and the level of RTW adaptability was assessed using the Adaptability of Returning to Work for Cancer Survivors (ARTW-CS) scale. Multiple linear regression analysis was used to control for confounding factors, and a simple effect analysis was performed on the interaction term. RESULTS: After controlling for sociodemographic, work-related, and health-related factors, the findings indicated a significant correlation between "adaptation and planning" and QWL score (p < 0.05). Further analysis revealed that "RTW gradualness" and "support seeking" had an interaction effect (p = 0.021). The simple effect analysis demonstrated that when the "RTW gradualness" score was ≥ 16 points, nurses with a high "support seeking" score (≥ 7 points) exhibited a significantly better QWL than those with a low "support seeking" score (< 7 points) (p < 0.001). CONCLUSION: The interaction between "RTW gradualness" and "support seeking" in the ARTW-CS scale significantly impacted the QWL of the NCSs, underscoring the importance of implementing a gradual career plan and seeking support to enhance QWL.
