Abstract
Objective This study aims to explore the subgroups and networks of symptom clusters in breast cancer patients undergoing chemotherapy, and to provide effective interventions for the core symptoms. Methods A cross-sectional survey was conducted at four comprehensive hospitals in Foshan City, China, from August to November 2023. A total of 292 participants completed the social determinants of health questionnaire, the numerical rating scale (NRS), the Pittsburgh sleep quality index (PSQI), the Chinese version of the cancer fatigue scale (CFS), and the hospital anxiety and depression Scale (HADS). Latent class analysis (LCA) was utilized to distinguish subgroups, and network analysis was utilized to identify core symptoms among different subgroups. Results Breast cancer patients undergoing chemotherapy exhibit symptoms were divided into two subgroups: the high burden group of symptoms (72.3%, Class 1) and the low burden group of symptoms (27.7%, Class 2). Education attainment, work status, family monthly income per capita, and daily sleep duration (hours) were associated with subgroup membership. "Panic feelings" (# HADS-A11) were the core symptom in both the full sample and Class 2, while "tension or pain" (# HADS-A1) was the core symptom in Class 1. Conclusions The core symptoms of fear, enjoyment, nervousness, and pain varied across subgroups of patients and could inform the current strategies for symptom management in breast cancer chemotherapy patients.

Abstract
OBJECTIVE Whether women with breast cancer experience more severe menopause symptoms than comparison women without a history of breast cancer diagnosis remains unclear. We aimed to investigate whether women with breast cancer undergoing chemotherapy experience more severe menopause symptoms than comparison women and explore various factors influencing menopause symptoms in women with breast cancer undergoing chemotherapy. METHODS This cross-sectional observational study recruited 423 women with breast cancer undergoing chemotherapy and 1,829 community women without breast cancer. All participants completed a questionnaire assessing menopause symptoms using the Menopause Rating Scale and general characteristics (eg, sociodemographic and clinical data). Propensity score matching was used to reduce the confounders between the two groups. Student's t test or Mann-Whitney U test and chi-square tests were used to compare the differences in menopause symptoms between the two groups. Multivariate linear regression analysis was performed to explore various factors influencing menopause symptoms in women with breast cancer undergoing chemotherapy. RESULTS After propensity score matching, 808 participants were included. The mean ages of women with breast cancer undergoing chemotherapy and comparison women were 49.58 and 49.10 years, respectively. Women with breast cancer undergoing chemotherapy experienced significantly more severe vasomotor symptoms than comparison women. However, comparison women had higher Menopause Rating Scale scores and more severe menopause symptoms than women with breast cancer undergoing chemotherapy. Age, occupational status, chemotherapy-induced amenorrhea, family history of cancer, chemotherapy stage, mindfulness, resiliency, and illness perception were associated with menopause symptoms in women with breast cancer undergoing chemotherapy. CONCLUSIONS Vasomotor symptoms are prominent among women with breast cancer undergoing chemotherapy. Understanding the factors contributing to menopause symptoms is crucial for healthcare practitioners to develop supportive guidelines for the well-being of women with breast cancer undergoing chemotherapy.

Abstract
Nonalcoholic fatty liver disease (NAFLD) is a prevalent condition among postmenopausal women that can lead to severe liver dysfunction and increased mortality. In recent years, research has focused on identifying potential lifestyle dietary interventions that may prevent or treat NAFLD in this population. Due to the complex and multifactorial nature of NAFLD in postmenopausal women, the disease can present as different subtypes, with varying levels of clinical presentation and variable treatment responses. By recognizing the significant heterogeneity of NAFLD in postmenopausal women, it may be possible to identify specific subsets of individuals who may benefit from targeted nutritional interventions. The purpose of this review was to examine the current evidence supporting the role of three specific nutritional factors-choline, soy isoflavones, and probiotics-as potential nutritional adjuvants in the prevention and treatment of NAFLD in postmenopausal women. There is promising evidence supporting the potential benefits of these nutritional factors for NAFLD prevention and treatment, particularly in postmenopausal women, and further research is warranted to confirm their effectiveness in alleviating hepatic steatosis in this population.

Abstract
PURPOSE Dietary intake and patients' quality of life (QoL) are important supportive care issues in breast cancer survivorship. This study aimed to identify dietary pattern before and after breast cancer diagnosis. In addition, the association between dietary patterns and QoL were cross-sectionally and longitudinally investigated. METHODS A breast cancer cohort which included 1462 Chinese women were longitudinally interviewed at four time-points, namely baseline, 18-, 36-, and 60 months after diagnosis. At each follow-up, validated food frequency questionnaires (FFQ) were used to assess patients' dietary intake, and factor analysis was used to derive dietary patterns. European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ-C30) were used to measure QoL at each follow-up. This study included 1368, 1226, 1079 and 1095 patients with invasive disease who completed assessment at baseline, 18-, 36- and 60-month follow-up and had detailed data of dietary intake and QoL. RESULTS Based on data obtained at 18-month follow-up, two major dietary patterns were identified: "grain and animal food pattern" and "vegetables and fruits pattern". Similar dietary patterns were obtained at baseline, 36- and 60- month follow-up. Generalized Estimating Equations (GEE) were used to analyze the longitudinal associations between dietary patterns and QoL over the four follow-ups. High intake of grain and animal food was inversely associated with scores for role functioning (B = - 0.744; 95%CI - 0.147 to - 0.017), dyspnea (B = - 0.092; 95%CI - 0.092 to - 0.092) and constipation (B = - 1.355; 95%CI - 2.174 to - 0.536). Vegetables and fruits intake were positively associated with scores for global health status/QoL (B = 1.282; 95%CI 0.545-2.019), physical functioning (B = 0.545; 95%CI: 0.037-1.053), emotional functioning (B = 1.426; 95%CI 0.653-2.200) and cognitive functioning (B = 0.822; 95%CI 0.007-1.637), while inversely associated with scores for nausea and vomiting (B = - 0.382; 95%CI - 0.694 to - 0.071), dyspnea (B = - 0.570; 95%CI - 0.570 to - 0.570), insomnia (B = - 1.412; 95%CI - 2.647 to - 0.177), loss of appetite (B = - 0.722; 95%CI - 1.311 to - 0.132), constipation (B = - 2.028; 95%CI - 2.775 to - 1.281) and diarrhea (B = - 0.929; 95%CI - 1.481 to - 0.377). CONCLUSION This study suggested that high adherence to "grain and animal food pattern" or "vegetables and fruits pattern" was significantly associated with several aspects of QoL. For instance, vegetables and fruits pattern appears to have beneficial effect on global health status/QoL among Chinese breast cancer patients. Prospective follow-up data could further confirm whether a specific dietary pattern has impact on cancer outcomes.

Abstract
Simple Summary Engaging in sports activities is strongly encouraged for cancer survivors. We aim to investigate the association between the level of sports activities participation post-diagnosis and quality of life (QoL) among Chinese women with early-stage breast cancer during the first five years of survival. Notably, we confirm in this work that regular participation in sports activities following cancer diagnosis may have a positive effect on patients’ QoL. Abstract Evidence about the association between the level of sports activities participation post-diagnosis and quality of life (QoL) among Chinese women with early-stage breast cancer is limited. A validated modified Chinese Baecke questionnaire was used to prospectively measure sports activities among a breast cancer cohort at four time-points: baseline and 18, 36, and 60 months after diagnosis (sports activities during the previous 12 months before each interview); QoL was measured at the same time. In total, 1289, 1125, and 1116 patients were included in the analyses at 18-, 36- and 60-month follow-up, respectively. The percentages of patients who belonged to no (0 metabolic equivalent of task (MET)-hours per week), low-level (<10 MET-hours/week), and high-level (≥10 MET-hours/week) sports activities group were 20.7%, 45.5%, and 33.8% at 18-month follow-up, respectively; the corresponding figures at 36 and 60 months differed slightly. Using data from the three follow-ups, generalized estimating equation (GEE) analyses showed that higher levels of sports activities participation were associated with better QoL in several items as well as fewer symptoms. The present findings in Chinese women with breast cancer provide important evidence on the beneficial effect of regular participation in sports activities following cancer diagnosis on patients’ QoL.

Weight and waist-to-hip ratio change pattern during the first five years of survival: data from a longitudinal observational Chinese breast cancer cohort. BMC Cancer 2021; 21:839. [PMID: 34284751 PMCID: PMC8293589 DOI: 10.1186/s12885-021-08554-5] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/17/2021] [Accepted: 06/17/2021] [Indexed: 11/10/2022] Open
Abstract
Background Body weight management was an important component in breast cancer survivorship care. The present study described the change patterns of body weight and waist-to-hip ratio (WHR) during the first 5 years of survival, and investigated potential factors associated with very substantial changes. Patients and methods Based on a longitudinal cohort with 1462 Chinese women with breast cancer, anthropometric measurements including body weight, height, waist and hip circumferences were measured by trained interviewers following standard protocol at four time-points: baseline at study entry, 18-, 36- and 60-months follow up assessments (termed as T0, T1, T2 and T3, respectively). Body height was measured at baseline and body weight at cancer diagnosis were retrieved from medical record. Results Compared to weight at breast cancer diagnosis, the median weight change was − 0.5 kg, 0 kg, + 0.5 kg, and + 1 kg at T0, T1, T2 and T3, respectively. During the first 5 years of survival, the proportion of women who were obese have slightly increased. At 60-months after diagnosis, only 14.3% of women had weight gain by > 5 kg; and the percentage of women who had weight gain by > 10% was 10.7%. Nearly half of patients had abdominal obesity at study entry, and this proportion were gradually increased to nearly 70% at 60-months follow-up. Multivariate analysis indicated that older age, and frequent sports participation during the first 5 years of survival were related to lower risk of very substantial weight gain (> 10%) at 60-month follow-up; patients aged 40–49 years, having ≥2 comorbidities and ER negative were associated with less likelihood of very substantial WHR substantial increase (> 10%) at 60-month follow-up. Conclusion Weight gain was modest in Chinese breast cancer survivors during the first 5 years of survival, while central adiposity has become a contemporary public health issue. The incorporation of healthy weight and abdominal circumference patient education and management has a potential to improve cancer survivorship.

Abstract
Background Evidence of the association between dietary pattern and outcomes of breast cancer was limited in Asian women, including Chinese. Patients and Methods A prospective cohort study was initiated among Chinese breast cancer patients to investigate lifestyle habits and outcomes of breast cancer. At each follow-up, validated food frequency questionnaires (FFQ) were used to assess patients’ dietary intake. This study included 1226 patients with invasive early-stage breast cancer with detailed data at 18-month follow-up after cancer diagnosis. Factor analysis was used to derive dietary patterns, whereby two dietary patterns were identified. Cox proportional hazards models were used to investigate associations between dietary patterns and time to outcome, including breast cancer recurrence, overall mortality and breast cancer-specific mortality. Results With a median follow-up time of 54.1 months, 165 patients had breast cancer recurrence and 98 deaths occurred. Two dietary patterns were identified: “Western dietary pattern” characterized by high intake of refined grains and cakes, red and processed meat and oil; “healthy dietary pattern” characterized by high consumption of vegetables and fruits. Participants in the highest tertile of “Western dietary pattern” did not have a higher risk of breast cancer recurrence (Ptrend = 0.89), overall mortality (Ptrend = 0.48) and breast cancer-specific mortality (Ptrend = 0.75). Similarly, a null association existed between “healthy dietary pattern” and outcomes of breast cancer. Conclusion Neither dietary pattern was associated with risk of breast cancer recurrence, all-causes death or death from breast cancer. Prospective follow-up is still needed to further confirm the association between specific dietary pattern and outcomes of breast cancer.

Abstract
BACKGROUND There is concern that the estrogen-like effects of soy isoflavones may stimulate mammary tumor growth and interfere with the efficacy of breast cancer treatment. This study aimed to examine prospectively the associations of dietary soy isoflavone intake with all-cause mortality and breast cancer (BC) specific mortality and recurrence among BC survivors. DESIGN The study included 1460 Chinese women with early-stage incident BC. Pre-diagnosis and early post-diagnosis soy food intakes were assessed at study entry, and at 18-month follow-up using validated soy food frequency questionnaire. Associations of soy isoflavone intake with prognostic outcomes within 48 months were examined using multivariable adjusted Cox proportional hazards models. RESULTS We observed increasing pre-diagnosis and early post-diagnosis soy isoflavone intakes up to the third quartile (Q3) were associated with reductions for adverse prognostic outcomes. Relative to the lowest quartile (Q1), the hazard ratios (HRs) for all-cause mortality for pre-diagnosis and post-diagnosis Q3 intake were respectively 0.34 (95% CI, 0.16-0.74), and 0.44 (95% CI, 0.22-0.89). A similar risk reduction was observed for pre- and post-diagnosis intakes and BC-specific mortality when comparing Q3 versus Q1 with the respective HRs 0.36 (95% CI, 0.16-0.82), and 0.49 (95% CI, 0.23-1.01). Subgroup analyses showed more favourable prognostic outcomes in association with moderate soy intake among premenopausal women, those with triple negative cancer and recipients of tamoxifen treatment. CONCLUSION Moderate soy isoflavone intake was associated with favourable prognostic outcomes in Chinese early stage BC survivors.

METHODS A prospective cohort study enrolled 1462 Chinese women with early-stage breast cancer, and longitudinally visited those patients at four time-points, namely baseline (T0), 18- (T1), 36- (T2), and 60-month (T3) after diagnosis. This study included 992 patients who were disease-free during the first 5 years of survival and who had completed QoL assessments at all four time-points. RESULTS The score of global health status/QoL improved gradually (T1, T2, T3 > T0; P < 0.001 for overall comparisons). Social functioning score significantly improved when compared to that of T0 (T1, T2, T3 > T0; P < 0.001 for overall comparisons). In contrast, cognitive functioning score decreased (T0 > T1, T2, T3; P < 0.001 for overall comparisons). Scores of physical functioning, role functioning and emotional functioning showed a fluctuated picture, with the highest score achieved at T1. In symptoms profile, most of them scored lowest at T1 (best QoL). Multivariate analysis showed that several characteristics significantly correlated to changes in QoL from T0 to T3. For instance, patients with higher education had better recovery of physical functioning, role functioning, and social functioning. CONCLUSION During the first 5 years of survival, patients' global health status/QoL improved over time, social functioning consistently improved, but cognitive functioning steadily deteriorated. Most of functioning domains and symptoms improved at 18-month follow-up, but such improvements were not maintained and even deteriorated at 36- and 60-month post-diagnosis. This study suggested that some interventions should be investigated during such period.
