Association between body composition and subsequent cardiovascular diseases among 5-year breast cancer survivors.

BACKGROUND AND AIMS: Cardiovascular disease (CVD) remain one of the leading causes of mortality in breast cancer survivors. This study aimed to investigate the association between body composition and subsequent CVD in breast cancer survivors. METHODS AND RESULTS: A retrospective cohort study of more than 70 thousand 5-year breast cancer survivors aged 40 years or older was conducted using data from the National Health Insurance Service of South Korea. Based on the percentage of predicted lean body mass (pLBMP), appendicular skeletal muscle mass (pASMP), and body fat mass (pBFMP), which were calculated using prediction equations with anthropometric data and health habits, groups were equally divided into quartiles. The risk of CVD was evaluated using multivariate Cox proportional hazards regression. Compared to those with the lowest pLBMP and pASMP, those with the highest pLBMP and pASMP had a 38% and 42% lower risk of CVD, respectively. In contrast, those with the highest pBFMP had a 57% higher risk of CVD compared to those with the lowest pBFMP. Each 1 % increase in pLBMP and pASMP was associated with a decreased risk of CVD [pLBMP, adjusted hazard ratio (aHR): 0.96, 95% CI 0.94-0.98, p < 0.05; pASMP, aHR: 0.91, 95% CI 0.87-0.95, p < 0.05] while each 1 % increase in pBFMP was associated with the increased risk of CVD (aHR: 1.05, 95% CI 1.03-1.07, p < 0.01). CONCLUSION: In this cohort study, a high pLBMP, a high pASMP, and a low pBFMP were associated with a lower risk of CVD.

Obstetric and perinatal outcomes in women with previous breast cancer: a nationwide study of singleton births 1973-2017.

STUDY QUESTION: What are the obstetric and perinatal outcomes in births to breast cancer survivors compared to women without previous breast cancer? SUMMARY ANSWER: Women who conceived during the first 2 years following a breast cancer diagnosis had a higher risk for preterm birth, induced delivery, and cesarean section, while no increased risks were observed in births conceived later than 2 years after a breast cancer diagnosis. WHAT IS KNOWN ALREADY: A recent meta-analysis found higher risks of cesarean section, preterm birth, low birthweight, and small for gestational age in pregnancies among breast cancer survivors. Less is known about rarer outcomes such as pre-eclampsia or congenital malformations. STUDY DESIGN SIZE DURATION: We conducted a population-based matched cohort study including all breast cancer survivors who gave birth to singletons 1973-2017 in Sweden, identified through linkage between the Swedish Cancer Register, the Medical Birth Register, and the National Quality Register for Breast Cancer. PARTICIPANTS/MATERIALS SETTINGS METHODS: Each birth following breast cancer (n = 926) was matched by maternal age at delivery, parity, and calendar year at delivery to 100 births in a comparator cohort of women (n = 92 490). Conditional logistic and multinomial regression models estimated relative risks (RR) with 95% CI. Subgroup analyses by time since diagnosis and type of treatment were performed. MAIN RESULTS AND THE ROLE OF CHANCE: Previous breast cancer was associated with higher risks of induced delivery (RR; 1.3, 1.0-1.6), very preterm birth (RR; 1.8, 1.1-3.0), and planned preterm birth (RR; 1.6, 1.0-2.4). Women who conceived within 1 year after breast cancer diagnosis had higher risks of cesarean section (RR; 1.7, 1.0-2.7), very preterm birth (RR; 5.3, 1.9-14.8), and low birthweight (RR; 2.7, 1.4-5.2), while the risks of induced delivery (RR; 1.8, 1.1-2.9), moderately preterm birth (RR; 2.1, 1.2-3.7), and planned preterm birth (RR; 2.5, 1.1-5.7) were higher in women who conceived during the second year after diagnosis. Women who conceived later than 2 years after breast cancer diagnosis had similar obstetric risks to their comparators. LIMITATIONS REASONS FOR CAUTION: As information on the end date of treatment was unavailable, the time between the date of diagnosis and conception was used as a proxy, which does not fully capture the effect of time since end of treatment. In addition, treatments and clinical recommendations have changed over the long study period, which may impact childbearing patterns in breast cancer survivors. WIDER IMPLICATIONS OF THE FINDINGS: Risks of adverse obstetric outcomes in breast cancer survivors were confined to births conceived within 2 years of diagnosis. As family building holds significance for numerous young breast cancer patients, these findings are particularly important to inform both breast cancer survivors and clinicians about future reproductive outcomes.

Physical rehabilitation program for cardiorespiratory health and quality of life among breast cancer survivors in UAE: protocol for a randomized control trial.

BACKGROUND: Cancer is a medical condition where some cells of the body reproduce uncontrollably and metastasize to other parts of the body. The burden of the disease is significantly high both at the global and national levels. In UAE, cancer was found to be the third leading cause of death. Breast cancer has been ranked first due to its prevalence, incidence, and mortality in UAE. Breast cancer survivors have significantly poor cardiovascular tolerance which affects their quality of life (QoL), even after the carcinoma has been treated or removed. Thus, the protocol aims to analyze the changes in cardiovascular endurance and QoL domains for breast cancer survivors in the United Arab Emirates using a long-term 2-month physical rehabilitation. METHODS: A total of 60 breast cancer survivors would be included in the study using a randomized controlled allocation of a 2-month physical rehabilitation intervention program with 3 months of follow-up. The intervention would target the cardiovascular endurance component of the participants to improve their physical well-being and quality of life ultimately. DISCUSSION: The findings of the study would have high clinical significance among breast cancer survivors in the UAE. The proposed physical rehabilitation program could be beneficial in improving cardiovascular endurance and thereby reduce the risk of mortality among breast cancer survivors. In addition, the physiological benefits of the exercise program could improve their quality-of-life domains including physical, mental, and social well-being. On a larger view, it could also help to reduce the economic burden on the health system due to associated complications. TRIAL REGISTRATION: ClinicalTrials.gov NCT06013527.

Adherence to the American Cancer Society guidelines on nutrition and physical activity for cancer survivors and biomarkers of inflammation among breast cancer survivors.

OBJECTIVES: This study investigated whether adherence to the overall lifestyle recommendations in the American Cancer Society (ACS) guidelines on nutrition and physical activity for cancer survivors was associated with inflammation in breast cancer survivors. METHODS: The study included 409 women who had undergone breast cancer surgery at least 1 year before enrollment. A generalized linear model was used to estimate the least square means and 95% confidence intervals of plasma levels of inflammatory markers according to lifestyle factors defined in terms of adherence to the ACS guidelines. RESULTS: Higher overall adherence scores were associated with lower levels of high-sensitivity C-reactive protein (hs-CRP) (p for trend=0.015) and higher levels of adiponectin (p for trend=0.009). Similar significant associations of hs-CRP (p for trend= 0.004) and adiponectin (p for trend=0.010) levels were observed with the score for the body mass index (BMI) component of the adherence score. A higher diet component score was associated with a higher adiponectin level (p for trend=0.020), but there was no significant association for the physical activity component score. CONCLUSIONS: The present study's findings suggest that maintaining a healthy lifestyle according to the ACS guidelines was associated with beneficial effects on inflammatory marker levels, especially hs-CRP and adiponectin, among breast cancer survivors. Among the 3 components of lifestyle guidelines, the BMI component exhibited the most similar tendency to the overall adherence score in relation to inflammatory indicators. Further prospective and intervention studies are needed to investigate longitudinal associations between lifestyle factors and inflammatory markers among breast cancer survivors.

Lesbian and bisexual breast cancer survivors' post-treatment resource needs.

PURPOSE: The purpose of our study was to identify and describe determinants of lesbian and bisexual breast cancer survivors' post-treatment resources. METHODS: We used a cross-sectional descriptive study design. The data reported here were gathered as part of OUT: The National Cancer Survey, administered electronically from September 2020 to March 2021 via social media and community partners. We used descriptive statistics, Fisher's exact tests, and thematic analysis to analyze survivor perceptions of information availability, treatment environment, care plans, social support, and health. RESULTS: Of those who participated in the survey, (N =430) 366 identified as lesbian, and 64 identified as bisexual. Mean age was 58.6 years (range 21 - 91 years). Fewer than 11% of our sample indicated they could find helpful information about being a queer person with cancer during their treatment. Over 75% of our sample that received a cancer survivorship care plan indicated that their plan did not include resources for queer individuals. CONCLUSIONS: Affirming cancer treatment environments and resources tailored to the needs of lesbian and bisexual breast cancer survivors are critical for reducing disparities. IMPLICATIONS FOR CANCER SURVIVORS: Survivorship care plans should include resources for queer individuals as a part of holistic cancer care.

Evaluating a Remotely Delivered Cardio-Oncology Rehabilitation Intervention for Patients With Breast Cancer (REMOTE-COR-B): Protocol for a Single-Arm Feasibility Trial.

BACKGROUND: Exercise rehabilitation is a promising strategy for reducing cardiovascular disease risk among patients with breast cancer. However, the evidence is primarily derived from programs based at exercise centers with in-person supervised delivery. Conversely, most patients report a preference for home-based rehabilitation. As such, there is a clear need to explore strategies that can provide real-time supervision and coaching while addressing consumer preferences. Evidence from cardiac rehabilitation has demonstrated the noninferiority of a smartphone-based telerehabilitation approach (REMOTE-CR) to improve cardiorespiratory fitness in people with cardiovascular disease compared to a center-based program. OBJECTIVE: This study aims to assess the feasibility, safety, and preliminary efficacy of the REMOTE-CR program adapted for patients with breast cancer at risk of cardiotoxicity (REMOTE-COR-B). We will also assess the satisfaction and usability of REMOTE-COR-B. METHODS: We will conduct a single-arm feasibility study of the REMOTE-COR-B program among patients with stage I-III breast cancer who are at risk of cardiotoxicity (taking treatment type and dose, as well as other common cardiovascular disease risk factors into account) and who are within 24 months of completing primary definitive treatment. Participants (target sample size of 40) will receive an 8-week smartphone-based telerehabilitation exercise program involving remotely delivered real-time supervision and behavior change support. The platform comprises a smartphone and wearable heart rate monitor, as well as a custom-built smartphone app and web application. Participants will be able to attend remotely monitored exercise sessions during set operating hours each week, scheduled in both the morning and evening. Adherence is the primary outcome of the trial, assessed through the number of remotely monitored exercise sessions attended compared to the trial target (ie, 3 sessions per week). Secondary outcomes include additional trial feasibility indicators (eg, recruitment and retention), safety, satisfaction, and usability, and objective and patient-reported efficacy outcomes (cardiovascular fitness, quality of life, fatigue, self-reported exercise, self-efficacy, habit strength, and motivation). Adherence, feasibility, and safety outcomes will be assessed during the intervention period; intervention satisfaction and usability will be assessed post intervention; and objective and patient-reported efficacy outcomes will be assessed at baseline, post intervention (2-month postbaseline assessment), and at follow-up (5-month postbaseline assessment). RESULTS: Recruitment for this trial commenced in March 2023, and 7 participants had been recruited as of the submission of the manuscript. The estimated completion date for the project is October 2024, with results expected to be published in mid-2025. CONCLUSIONS: The REMOTE-COR-B intervention is a novel and promising approach to providing exercise therapy to patients with breast cancer at risk of cardiotoxicity who have unique needs and heightened safety risks. This project will provide important information on the extent to which this approach is satisfactory to patients with breast cancer, safe, and potentially effective, which is necessary before larger-scale research or clinical projects.

¿La Respuesta Psicofisiológica de Estrés-Relajación es la Misma en todas las Pacientes Sobrevivientes de Cáncer? / Is the Psychophysiological Stress-Relaxation Response the Same in all Cancer Survivors?

Resumen Un sobreviviente de cáncer padece continuamente manifestaciones autonómicas debidas a la enfermedad, su tratamiento oncológico, y el estrés psicológico con que se enfrenta continuamente. Una de las medidas psicofisiológicas utilizada para la valoración del estrés es la disminución de la temperatura periférica. En contraparte, los procedimientos psicológicos de relajación para el manejo de estrés buscan incrementar la temperatura. Sin embargo, se desconoce si esta respuesta es igual en todas pacientes. El objetivo de esta investigación fue examinar los cambios de temperatura durante un protocolo de estrés psicosocial y relajación en pacientes sobrevivientes de cáncer de mama. Adicionalmente, se evaluó el autorreporte de dolor y su interferencia con el funcionamiento psicosocial. Los resultados mostraron variaciones de temperatura periférica en las pacientes; sin embargo, no todas las pacientes presentaron el mismo patrón de temperatura, encontrando 3 subgrupos de pacientes, cuyas trayectorias lineales de temperatura permitieron generar un pronóstico afectivo para el manejo de estrés. Por autorreporte, no se encontraron diferencias psicosociales entre los subgrupos, aunque sí se encontró una asociación inversa entre la interferencia del sueño y la temperatura periférica. Se concluye que la temperatura periférica permite distinguir a las pacientes que se les dificulta el manejo del estrés psicosocial de aquellas que se benefician de los procedimientos psicológicos de relajación.

Abstract A cancer survivor continually suffers from autonomic manifestations due to the disease, their cancer treatment, and the psychological stress they continually face. One of the psychophysiological measures used to assess stress is the decrease in peripheral temperature. In contrast, psychological relaxation procedures for stress management seek to increase temperature. However, it is unknown if this response is the same in all patients. This research examined breast cancer survivors' temperature changes during psychosocial stress and relaxation protocol. Additionally, self-reported pain and its interference with psychosocial functioning were evaluated. The results showed peripheral temperature variations in the patients; however, not all patients presented with the same temperature pattern, finding three subgroups of patients whose linear temperature trajectories allowed generating an affective prognosis for stress management. By self-report, no psychosocial differences were found between the subgroups, although an inverse association between sleep interference and peripheral temperature was found. It is concluded that peripheral temperature distinguishes patients who find it challenging to manage psychosocial stress from those who benefit from psychological relaxation procedures.

Variables asociadas al ejercicio físico en supervivientes de cáncer de mama / Variables associated with physical exercise in breast cancer survivor

Las mujeres supervivientes de cáncer de mama (MSCM) pueden sufrir varios efectos secundarios y secuelas, por ello se recomienda la práctica regular de ejercicio físico (EF), como una estrategia que ha demostrado ser de ayuda para mitigar los síntomas negativos físicos y psicológicos provocados por el cáncer y sus tratamientos. Objetivo: conocer si las variables de: sintomatología de ansiedad, sintomatología depresiva, estilos de afrontamiento, nivel de apoyo social y barreras, se asocian al EF en MSCM. Método: Se trata de un estudio descriptivo en mujeres que acuden a la sede de Madrid de la Asociación Española Contra el Cáncer (AECC). Las variables analizadas son: realizar ejercicio físico regular o no, evaluado con el cuestionario de etapas de cambio para el ejercicio físico (URICA E2), la sintomatología de ansiedad a través del inventario de ansiedad de Beck (BAI), la sintomatología depresiva con el inventario de depresión de Beck (BDI-II), para evaluar los estilos de afrontamiento se utilizó el cuestionario COPE-28, el nivel de apoyo social a través del Medical Outcomes Study-Social Support Survey (MOS) y un cuestionario para las barreras diseñado por Kostiuk (2016). La muestra constaba de 200 mujeres, de las cuales finalmente participaron 165, con una media de edad de 49,17 años (DT=7,54). Resultados: el 62,4% afirmó tener hijos, el 50,3% estaban casadas, el 75,8% con estudios universitarios, en activo el 57, 8%. En cuanto a las variables clínicas, el 100% de las mujeres fue intervenida quirúrgicamente, el 78,2% recibió además quimioterapia, el 78,8% radioterapia y el 78,8% hormonoterapia. Fueron el 71,5 % (118) de las mujeres que refirieron practicar EF de forma regular, y 28,5% (47) no lo hacían. Las variables que se asociaron a la práctica de EF fueron: la sintomatología depresiva (AU)

Breast cancer survivors (BCS) frequently present several secondary effects and sequelae. Physical exercise has emerged as a strategy that helps people to mitigate the negative physical and psychological symptoms caused by cancer and its treatments. Objective: The objective of this article is to know if the following variables: anxiety symptomatology, depressive symptomatology, coping styles, level of social support and barriers, were associated with physical exercise in women that have suffered from breast cancer. Method: This is a descriptive study in women who have attend the Spanish Association Against Cancer in Madrid. The variables we have analyzed were: performing regular physical exercise or not, evaluated with the stages of change questionnaire for physical exercise (URICA-E2), anxiety symptomatology through the Beck Anxiety Inventory (BAI), depressive symptomatology with the Beck Depression Inventory (BDI-II), to assess coping styles we used the COPE-28 questionnaire, the level of social support through the Medical Outcomes Study-Social Support Survey (MOS) and a brief questionnaire for the barriers to physical exercise designed by Kostiuk (2016). Results: The sample consisted of 165 breast cancer survivors, with a mean age of 49.17 years (SD=7.54); 62.4% claimed to have children, 50.3% were married, 75.8% had university studies, 57.8% were active. Regarding the clinical variables, 100% of the women underwent surgery, of whom 78.2% also received chemotherapy, 78.8% radiotherapy and 78.8% hormone therapy. There were 71.5 % (118) women who reported practicing physical exercise on a regular basis, and 28.5% (47) did not. The variables that were associated with the regular practice of physical exercise were (AU)

El Modelo Transteórico y el ejercicio en supervivientes de cáncer de mama / Transtheoretical Model and exercise in breast cancer survivors

Se presenta una revisión sistemática sobre el uso del Modelo transteórico del cambio (MTC) como predictor de adherencia al ejercicio físico (EF) en supervivientes de cáncer de mama. La revisión sistemática de literatura se hizo siguiendo el método PRISMA, en las bases de datos: Scopus, Pubmed y Psycinfo. Tanto en inglés como en español. Se incluyeron 13 artículos publicados desde junio de 2005 hasta junio de 2020. Todos ellos utilizaron constructos del MTC en sus programas. Los resultados muestran que las variables del MTC que presentan asociación con el EF son los estadios de cambio y la autoeficacia. De este modo las intervenciones que siguen el MTC ayudan a comprender la utilización del ejercicio. Sin embargo, estos resultados están limitados por el escaso tamaño de la muestra, los sesgos de selección y la falta de mediciones a largo plazo de los seguimientos. (AU)

A systematic review on the use of the Transtheoretical Model of Change (TTM) as a predictor variable of adherence to Physical Exercise (PE) in breast cancer survivors is presented. The systematic literature review was carried out following the PRISMA method in Scopus, Pubmed, and Psycinfo databases. Both in English and Spanish. Thirteen articles published from June 2005 to June 2020 were included. All of them used TTM constructs in their programs. The results show that the TCM variables that demonstrated its association with PE were stages of change and self-efficacy. Therefore, TCM-based interventions help to understand the adoption of exercise behavior. However, these findings are limited by the small sample size, selection biases, and lack of long-term measurements of follow-ups. (AU)

Dietary Intake Status among Korean Female Breast Cancer Survivors / 대한지역사회영양학회지

OBJECTIVES: We aimed to evaluate dietary intake among female breast cancer survivors in a cross-sectional study. METHODS: A total of 127 women who had breast cancer surgery at least 6 months before baseline were included. Dietary intake of female breast cancer survivors was assessed through self-reported 3 day-dietary records. To compare dietary intake between breast cancer survivors and general female population without cancer, we selected the 1:4 age matched women from the 2011 Korean National Health and Nutrition Examination Survey (KNHANES). In the KNHANES, participants were asked about their dietary intake using the 24-hour dietary recalls. We also examined whether dietary intake varied by age group, cancer stage, or time since surgery among breast cancer survivors. We used the generalized linear model to compare their dietary intakes. RESULTS: Intakes of total energy, beta-carotene, folate, vitamin C, plant iron and fruits were lower among breast cancer survivors with longer time since surgery compared to those with shorter time (p < 0.05). Breast cancer patients with higher stage at diagnosis tended to consume less legumes (p = 0.01) than those with lower stage. When we compared dietary intake between breast cancer survivors and the general female population without cancer, breast cancer survivors were more likely to consume most of macro- and micro-nutrients in larger quantity (p < 0.05) and adhere to healthier diet characterized by higher intakes of legumes, seed and nuts, vegetables and fishes and shells than the general female population who never had been diagnosed with cancer (p < 0.05). CONCLUSIONS: Our study results suggested that the intakes of nutrients and foods varied by time since surgery and cancer stage among breast cancer survivors and dietary intakes among breast cancer survivors differed from that in the general population. Further prospective studies are warranted to explore the association between dietary intakes of specific food items and survival among Korean breast cancer survivors.

Status of Exercise and Related Factors in Survivors of Breast Cancer

Purpose: The present study aimed to clarify the status of exercise and related factors among survivors of breast cancer. Methods: Questionnaires were distributed to survivors of breast cancer. The question items addressed the status of exercise participation, knowledge about the effects of exercise and need for support. Factors associated with exercise participation were analyzed using logistic regression analysis. Results: Among 293 valid responses (rate, 84.2%). Fifty-eight point four percent participated in exercise and 41.3% decreased exercise participation after being diagnosed with breast cancer. Furthermore, 91.9% needed support from health care providers regarding exercise. About 70% of respondents were aware that exercise improves sleep, but <50% knew that exercise ameliorates symptoms associated with breast cancer. Among seven factors, age, employment status and chemotherapy were associated with exercise status. Conclusion: Breast cancer survivors who are younger, employed and undergoing chemotherapy might not participate in exercise. The preventive effects of exercise on breast cancer and the importance of continuing daily exercise should be promoted. Health care providers should provide support for patients to participate in exercise considering the influence of treatment and physical capabilities.
