El objetivo de este estudio fue comparar la predicción del V̇O2máx. entre mujeres sobrevivientes de cáncer de mama y un grupo control (GC) de mujeres sin antecedentes de cáncer. Estudio de caso-control en que diecisiete mujeres en el grupo sobrevivientes de cáncer de mama (49.4 ± 8.9 años, índice de masa corporal [IMC] de 27.8 ± 2.7 kg·m-2) y 17 en el GC (47.9 ± 7.4 años, IMC de 26.2 ± 4.4 kg·m-2) fueron evaluadas. La prueba de caminata de seis minutos (PC6M) se evaluó con monitor de frecuencia cardíaca, tensiómetro digital, oxímetro de pulso y escala de Borg. El V̇O2máx. se estimó con ecuación que consideró la distancia recorrida, el peso corporal y la edad. El grupo de sobrevivientes caminó 34.8 metros más que el GC (p = .15; d = .51). También mostró una tendencia (p = .05), con un tamaño del efecto moderado (d = .76), hacia un aumento del V̇O2máx. (1.74 ± .26 L·min-1) comparado con el GC (1.56 ± .21 L·min-1). No hubo diferencias entre los grupos para las variables de frecuencia cardíaca, presión arterial y esfuerzo percibido durante la prueba (p > .05). Las participantes que recorrieron más distancia tuvieron más probabilidades de un mayor V̇O2máx. (odds ratio = 12.7; p = .002). Existieron diferencias en el V̇O2máx. entre los dos grupos, esta aptitud física debería considerarse para el tratamiento y control post-operatorio. Abstract. The aim of the study was to compare the prediction of the V̇O2max in breast cancer survivors and a control group (CG) of women without a history of cancer. It is a case-control study. Seventeen women in the breast cancer survivors (49.4 ± 8.9 years, body mass index [BMI] of 27.8 ± 2.7 kg·m-2) and 17 in the CG (47.9 ± 7.4 years, BMI of 26.2 ± 4.4 kg·m-2) were evaluated. The six-minute walk test (SMWT) was evaluated with a heart rate monitor, digital blood pressure monitor, pulse oximeter and the Borg scale. The V̇O2max it was estimated with an equation that considered the distance traveled, body weight and age. The survivors group walked 34.8 meters more than the CG (p = .15). In addition, group showed a trend (p = .05), with a moderate effect size (d = .76), towards an increase in V̇O2max (1.74 ± .26 L·min-1) compared to the CG (1.56 ± .21 L·min-1). There were no differences between the groups for the variables of heart rate, blood pressure and perceived exertion during the test (p > .05). The participants who covered the longest distance had a better chance of a V̇O2max higher (odds ratio = 12.7; p = .002). There were differences in the V̇O2max between groups, this physical fitness should be considered for post-operated treatment and monitoring.

Abstract Purpose The Trials within Cohorts (TwiCs) design aims to overcome problems faced in conventional RCTs. We evaluated the TwiCs design when estimating the effect of exercise on quality of life (QoL) and fatigue in inactive breast cancer survivors. Methods UMBRELLA Fit was conducted within the prospective UMBRELLA breast cancer cohort. Patients provided consent for future randomization at cohort entry. We randomized inactive patients 12–18 months after cohort enrollment. The intervention group (n = 130) was offered a 12-week supervised exercise intervention. The control group (n = 130) was not informed and received usual care. Six-month exercise effects on QoL and fatigue as measured in the cohort were analyzed with intention-to-treat (ITT), instrumental variable (IV), and propensity scores (PS) analyses. Results Fifty-two percent (n = 68) of inactive patients accepted the intervention. Physical activity increased in patients in the intervention group, but not in the control group. We found no benefit of exercise for dimensions of QoL (ITT difference global QoL: 0.8, 95% CI = − 2.2; 3.8) and fatigue, except for a small beneficial effect on physical fatigue (ITT difference: − 1.1, 95% CI = − 1.8; − 0.3; IV: − 1.9, 95% CI = − 3.3; − 0.5, PS: − 1.2, 95% CI = − 2.3; − 0.2). Conclusion TwiCs gave insight into exercise intervention acceptance: about half of inactive breast cancer survivors accepted the offer and increased physical activity levels. The offer resulted in no improvement on QoL, and a small beneficial effect on physical fatigue.

Tai Chi Chuan

Purpose: To investigate the effect of Tai Chi Chuan (TCC) to improve immune system and decrease pro-metastasis markers in early post-treatment breast cancer survivors. Methods: 130 post-treatment breast cancer survivors were recruited and randomized 1:1 into TCC group and wait-list (control) group. The TCC group practiced for a 60-minutes session once per week, for a total of 52 weeks. 115 forms of Yang-style TCC were taught by a Tai Chi master. Blood samples were taken from each subject and complete blood count was performed. The expressions of NKG2D protein, P-selectin, and vascular endothelial growth factor (VEGF) in plasma were measured. Lymphocyte activity was measured by cell proliferation reagent and ATP assay. Images of lymphocyte colony formation were taken with an inverted microscope. Results: At 52 weeks, TCC group demonstrated a significantly higher WBC (p=0.001) , a significantly higher NKG2D value (p=0.001) and a significantly lower VEGF value (p=0.005) when compared to the wait-list group. However, there was a small, non-significant change for P-selectin values between the breast cancer survivor groups. After 72h incubation, TCC group had a significant increase in lymphocyte proliferation (p=0.001) and greater area of lymphocyte clusters or colonies (p=0.001). Conclusion: The practice of TCC could stimulate tumor immunosurveillance via NKG2D and activate the immune response. VEGF, a marker playing an important role in breast cancer and its metastases, was also reduced in those who practiced TCC. As an alternative for conventional exercise, post-treatment breast cancer survivors may select TCC in their rehabilitation program.

Purpose: The purpose of this study was to examine the effects of a smart-care services program for breast cancer survivors on cognitive function and physical health. Methods: A quasi-experimental control group pretest posttest design was used. Subjects were recruited in D city, and data were collected from July 2017 to February 2018. The experimental group (n=24) participated in the smart-care services program, whereas the control group (n=26) received conventional management. The smart-care services program consisted of addressing cognitive function problems arising from chemotherapy, diet, exercise, head/neck massage and self-monitoring using smartphone applications and smart bands. All participants underwent assessments at baseline, at 6 weeks, and at 12 weeks. Data were analyzed using descriptive statistics (frequency, percentage, mean and standard deviation), a chi-squared test, t-test, and repeated measures ANOVA. Results: After the smart-care services program, significant differences were found between the groups in cognitive function (F=18.91, p<.001) and sleep time (F=9.25, p<.001). No significant differences were found between the groups in caloric consumption after the program. Conclusion: The smart-care services program significantly improved the level of cognitive function and sleep time for breast cancer survivors. The use of this smart-care services program for breast cancer survivors might be an effective nursing intervention tool for improving cognitive function and health behaviors.

Purpose The sequelae of cancer treatment may increase systemic inflammation and create a phenotype at increased risk of functional decline and comorbidities, leading to premature mortality. Little is known about how this trajectory compares with natural aging among peers of the same age without cancer. This longitudinal study investigated proinflammatory cytokines and comorbidity development over time among breast cancer survivors and a noncancer control group. Methods Women (N = 315; 209 with breast cancer and 106 in the control group) were recruited at the time of their work-up for breast cancer; they completed the baseline questionnaire, interview, and blood draw (lipopolysaccharide-stimulated production of interleukin [IL] -6, tumor necrosis factor-α, and IL-1β). Measures were repeated 6 and 18 months after primary cancer treatment (cancer survivors) or within a comparable time frame (control group). Results There were no baseline differences in comorbidities or cytokines between survivors and the control group. Over time, breast cancer survivors had significantly higher tumor necrosis factor-α and IL-6 compared with the control group. Survivors treated with surgery, radiation, and chemotherapy accumulated a significantly greater burden of comorbid conditions and suffered greater pain associated with inflammation over time after cancer treatment than did the control group. Conclusion Survivors who had multimodal treatment had higher cytokines and comorbidities, suggestive of accelerated aging. Comorbidities were related to inflammation in this sample, which could increase the likelihood of premature mortality. Given that many comorbidities take years to develop, future research with extended follow-up beyond 18 months is necessary to examine the evidence of accelerated aging in cancer survivors and to determine the responsible mechanisms.

Background: crying therapy is currently being applied in some countries to treat cancer patients, manage pain, and promote mental health. However, little nursing and medical research on the effects of crying therapy has been conducted in other parts of the world. This study aimed to develop a crying therapy program for breast cancer survivors and assess its effects. Interventions/method: data from 27 breast cancer survivors in South Korea were analyzed. The intervention, employing a single group, pre-post-test quasi-experimental design, was divided into three phases, and effects were verified for emotional (distress, fatigue, and mood conditions) and physiological (cortisol, immunoglobulin G, and blood pressure) variables. Results: there were significant changes in distress, mood changes, and immunoglobulin G and smaller changes in blood pressure postintervention. Fatigue and cortisol showed no significant changes. Conclusions: this study demonstrated the effectiveness of a short-term crying therapy program that can induce positive emotional changes and physiological effects in breast cancer survivors. This intervention can improve quality of life, indicating its value as a self-care program for cancer survivors.

Introduction The necessity of culturally competent Internet Cancer Support Groups (ICSGs) for ethnic minorities has recently been highlighted in order to increase its attractiveness and usage. The purpose of this study was to determine the preliminary efficacy of a culturally tailored registered-nurse-moderated ICSG for Asian American breast cancer survivors in enhancing the women’s breast cancer survivorship experience. Methods The study included two phases: (a) a usability test and an expert review; and (b) a randomized controlled pilot intervention study. The usability test was conducted among five Asian American breast cancer survivors using a one-month online forum, and the expert review was conducted among five experts using the Cognitive Walkthrough method. The randomized controlled pilot intervention study (a pre-test and post-test design) was conducted among 65 Asian American breast cancer survivors. The data were analysed using content analysis and descriptive and inferential statistics including the repeated ANOVA. Results All users and experts positively evaluated the program and provided their suggestions for the display, educational contents, and user-friendly structure. There were significant positive changes in the support care needs and physical and psychological symptoms ( p < 0.05) of the control group. There were significant negative changes in the uncertainty level of the intervention group ( p < 0.10). Controlling for background and disease factors, the intervention group showed significantly greater improvements than the control group in physical and psychological symptoms and quality of life ( p < 0.10). Discussion The findings supported the positive effects of ICSGs on support care needs, psychological and physical symptoms, and quality of life.
