Purpose: This study aimed to develop an app-based self-management program based on the transtheoretical model (TTM) for breast cancer survivors' exercise practice, as well as to investigate the program's effects on the stage of change for exercise, exercise self-efficacy, exercise decisional balance, exercise amount, and body composition. Methods: This non-randomized controlled study included 52 participants (26 in each of the experimental and control groups, respectively). An app-based self-management program based on the TTM was conducted with the experimental group for a 12-week period. The program comprised three components: individual coaching for each stage of change for exercise based on TTM, amount of exercise and body composition monitoring, and online self-help meetings. Results: Compared with the control group, the experimental group had significantly higher stages of change for exercise (p < .001), exercise self-efficacy (p < .001), exercise decisional balance (p = .002), exercise amount (p < .001), and body composition (body weight [p = .006], body mass index [p = .005], and body fat percentage [p = .010]) immediately and four weeks after the intervention. Conclusion: An app-based self-management program based on the TTM improves exercise behaviors in breast cancer survivors and provides physical benefits.

Purpose: The purpose of this study was to describe the impact of fatigue and distress on self-efficacy among breast cancer survivors and to provide a base for development of nursing intervention strategy to improve self-efficacy. Methods: A descriptive research design was used. The subjects were 158 patients who were either being treated or were receiving follow-up care at a university breast center in D City from May 30 to August 30, 2014. Structured questionnaires, Revised Piper Fatigue Scale, Distress Thermometer, and Self-Efficacy Scale for Self-Management of Breast Cancer were used to measure fatigue, distress, and self-efficacy. Data were analyzed using t-test, ANOVA, Pearson's correlation coefficients, and multiple regressions. Results: The mean scores of fatigue, distress, and self-efficacy were 3.83, 4.31, and 3.77, respectively. There were significant differences among participants in terms of educational background, current treatment methods, perceived health status, economic burden for fatigue and perceived health status for distress. Self-efficacy was impacted by age, educational background, marital status, average monthly income, perceived health status, and medical expenses. Fatigue, age, and the burden on medical expense had the most impact on self-efficacy, accounting for 17% of the variance. Conclusion: Fatigue should be managed to improve self-efficacy of breast cancer survivors. Therefore, nursing programs designed to decrease fatigue may be helpful.

BACKGROUND/OBJECTIVES: The aim of this study was to examine the validity and reproducibility of a food frequency questionnaire (FFQ) developed in Korea for breast cancer survivors. SUBJECTS/METHODS: Ninety-nine breast cancer survivors who completed an FFQ twice and three 3-day dietary records (DRs) between 2016-2017 were included. Energy and 14 nutrient intakes were calculated from FFQs and DRs. To determine the validity of the FFQ, energy-adjusted de-attenuated Pearson correlations between two FFQ assessments and the average of the three 3-day DRs were calculated, and to determine reproducibility, energy-adjusted Pearson correlations and degrees of agreement were calculated between the first and second FFQ assessments. RESULTS: Correlation coefficients of validity ranged from 0.29 (protein) to 0.47 (fat) (median value = 0.36) for the FFQ assessment and from 0.20 (riboflavin) to 0.53 (calcium) (median value = 0.37) for the second. Correlation coefficients of reproducibility ranged from 0.22 (sodium) to 0.62 (carbohydrate) (median value = 0.36). Regarding FFQ reproducibilities, percentage classifications of exact agreements for energy-adjusted nutrients ranged from 27.3% (sodium) and 45.5% (fat). A median 76.8% of participants were classified into the same or adjacent quartiles, while a median of 5.6% of participants were classified in extreme quartiles. Bland-Atman plots for the majority of data points of three macronutrients, calcium and vitamins A and C fell within limits of agreement. CONCLUSIONS: These results indicated that the newly developed FFQ for Korean breast cancer survivors has acceptable validity and reproducibility as compared with three 3-day DRs collected over a one-year period.

Purpose: The purpose of this study was to analyze the effects of a combined exercise program on the level of physical fitness and fatigue for cancer survivors. Methods: The subjects were all of 61 persons consisted of prostate cancer(n=22), breast cancer (n=20), and stomach cancer(n=19) survivors. The exercise program was composed of a wall exercise, a chair exercise, a towel exercise and a bottle exercise which lasted 50-60 minutes each, two times a week for 12 weeks. The outcome measures were the fat mass, the muscle mass, the grip strength, the sit and reach, the 6 minutes walk, & fatigue. Results: At the completion of the 12-week combined exercise program, there were statistically significant differences in the grip strength, the sit & reach, the 6 minutes walk, & fatigue for the prostate, breast, and stomach cancer survivors. But no significant differences were found in the muscle mass between the pretest and posttest. Conclusion: As the 12-week combined exercise program was proved to be an effective intervention for improving muscle strength, flexibility, cardiopulmonary fitness & fatigue, it is thought that the program can be utilized as a rehabilitation program for cancer survivors.

Purpose: This study aimed to analyze physical activity as measured by the International Physical Activity Questionnaire (IPAQ) and an actigraph in breast cancer survivors, as well as to identify their intention to participate in a physical activity program. Methods: Breast cancer patients who had been diagnosed for more than six months (N=135) at a university hospital participated from June 2012 to May 2013. Physical activity was measured using the Korean version of the IPAQ-Short Form and Actigraph GT3X plus an accelerator for seven consecutive days. Data analyses were conducted using the SPSS WIN 19.0 program. Results: Mean total physical activity was 2298.21 metabolic equivalent task (MET)-min/week as assessed by IPAQ and 150,140.57 counts/day as measured by an actigraph. There were statistically significant correlations between moderate physical activity from IPAQ and light intensity of physical activity from the actigraph (r=.735, p<.001), vigorous physical activity from IPAQ and vigorous intensity of physical activity from the actigraph (r=.871, p<.001), total physical activity from IPAQ and light intensity of physical activity from the actigraph (r=.825, p<.001), respectively. Most (80.7%) cancer survivors reported a positive attitude toward physical activity and 57.8% expressed a willingness to participate in a physical activity program. More than half (60%) of the subjects preferred walking, 80.6% preferred more than 30 minutes of exercise, and 57.1% wanted to engage in physical activity three times a week and preferred home-based activities. Perceived barriers included fatigue, lack of strength and pain. Conclusion: It is necessary to consider intensity, personal preferences, and patient-perceived barriers when developing physical activity programs for breast cancer survivors.

Breast cancer is the most frequently diagnosed cancer primarily affecting women and negatively impacting the individuals, families, and the health care system. Despite the well-known benefits of exercise for breast cancer survivors, rate of physical activity declines during adjuvant therapy and may not return to pre-diagnosis levels. In addition, low levels of adherence to exercise have been observed in this cohort. The challenge is to identify strategies that are effective in promoting exercise adherence. Several of the studies use social cognitive theory as a theoretical framework to design exercise interventions that encourage adherence. Within and without this framework, they have implemented interventions within the home and gym-based environments. Strategies used to encourage adherence to exercise programs and which are readily implemented in most situations have included distribution of print materials and pedometers, as well as recommendation from the oncologist. Other strategies that may be less feasible have included provision of trainers, gym memberships, regular phone-calls, and psychologist-lead stress management sessions.

Breast cancer is one of the most common cancers affecting women worldwide. Although the survival rate of breast cancer has increased, breast cancer still results in a high mortality rate. Breast cancer deaths are caused by metastasis that occurs in organ dysfunction. Recently, there have been many studies on circulating tumor cells (CTCs), which are related to breast cancer metastasis in the blood. Recent studies have demonstrated that some CTCs do not express epithelial markers. Therefore, in this study, total RNA was extracted from blood without separating out the CTCs, and the characteristics of the CTCs were analyzed by RT-qPCR. Cyclin D1 and twist-related protein 1 (TWIST1) are well-known markers for predicting the prognosis of patients with breast cancer. However, few studies have demonstrated the use of CCND1 and TWIST1 in blood as diagnostic and prognostic markers of breast cancer. In this study, patients with late-stage breast cancer had overexpressed CCND1 and TWIST1 than patients with different stages of breast cancer (P < 0.001 and P < 0.01, respectively). The relative expression level of CCND1 in survivors was higher than in patients who died (P = 0.06). The relative expression level of TWIST1 in survivors was lower than in patients who died (P = 0.08). Overall CCND1 and TWIST1 were not useful as markers for the diagnosis of breast cancer through blood. However, we showed the possibility of using CCND1 and TWIST1 as prognostic markers, and a large-scale study is needed to confirm the usefulness of these prognostic markers.
