Risk Factors for Breast Cancer-Related Lymphedema: An Umbrella Review.

BACKGROUND: Identification of risk factors facilitates the prevention of breast cancer-related lymphedema (BCRL). Several published systematic reviews have already addressed the risk factors for BCRL. This study aimed to systematically identify potential risk factors for BCRL and evaluate the quality of evidence. METHODS: The study followed methodologic guidance from the Joanna Briggs Institute, and the Cochrane Handbook. The following electronic databases were systematically searched from inception to 15 November 2022: PubMed, Embase, CINAHL, Web of Science, Scopus, CNKI, SinoMed, Wanfang, JBI Database, Cochrane Database, ProQuest, and PROSPERO. Two authors independently screened studies, extracted data, and assessed methodologic quality using AMSTAR2, risk of bias using ROBIS, and evidence quality using GRADE. The study evaluated overlap, assessed the small-study effect, and calculated the I2 statistic and Egger's P value as needed. RESULTS: The study included 14 publications comprising 10 meta-analyses and 4 systematic reviews. The authors identified 39 factors and 30 unique meta-analyses. In the study, 13 innate personal trait-related risk factors, such as higher body mass index (BMI) and axillary lymph nodes dissection, showed statistically significant associations with BCRL incidence. Breast reconstruction was found to be a protective factor. The methodologic quality was low or critically low. The majority of the systematic reviews and/or meta-analyses were rated as having a high risk of bias. Evidence quality was low for 22 associations and moderate for 8 associations. CONCLUSIONS: The currently identified risk factors for BCRL all are innate personal trait-related factors. Future well-designed studies and robust meta-analyses are needed to explore potential associations between behavioral-, interpersonal-, and environmental-related factors and BCRL, as well as the role of genetic variations and pathophysiologic factors.

Contemporaneous Symptom Networks of Breast Cancer-Related Upper Limb Lymphedema: A Network Analysis.

BACKGROUND: Upper limb lymphedema (ULL) is a common and deliberating complication for breast cancer survivors (BCSs). Breast cancer survivors with ULL reported a wide range of symptoms. However, little is known about symptom patterns and interrelationships among them. This study was designed to explore symptom clusters and construct symptom networks of ULL-related symptoms among BCSs and to identify the core symptoms. METHODS: This study is a secondary data analysis using datasets from three cross-sectional studies of BCSs in China. A total of 341 participants with maximum interlimb circumference ≥2 cm and complete responses in Part I of the Breast Cancer and Lymphedema Symptom Experience Index were included. Symptom clusters were identified through principal component analysis, and multiple linear regression analysis was employed to explore factors associated with severity of overall ULL-related symptoms. A contemporaneous network with 20 frequently reported symptoms were constructed after controlling for covariates. RESULTS: Three symptom clusters, including lymph stasis symptom cluster, nerve symptom cluster, and movement limitation symptom cluster, were identified. Postsurgery time, axillary lymph node dissection, and radiotherapy were associated with the severity of ULL-related symptoms. Tightness (rs = 1.379; rscov = 1.097), tingling (rs = 1.264; rscov = 0.925), and firmness (rs = 1.170; rscov = 0.923) were the most central symptoms in both networks with and without covariates. CONCLUSIONS: Breast cancer survivors with ULL experienced severe symptom burden. Tightness, tingling, and firmness were core symptoms of ULL among BCSs. Our findings demonstrated that the assessment and targeted intervention of specific core symptoms might help to relive effectively the burden of ULL-related symptom among BCSs.

Development and validation of a prediction model for frailty in breast cancer patients with extended survival.

BACKGROUND: Breast cancer (BC) patients with extended survival show a higher incidence of frailty. This study aimed to develop and validate a novel model combining sociodemographic factors (SF) and disease-related factors (DRF) to identify frailty in BC patients with extended survival. METHODS: This cross-sectional study examined data from 1167 patients admitted to a large urban academic medical centre. Three types of predictive models were constructed in the training set (817 patients): the SF model, the DRF model, and the SF + DRF model (combined model). The model performance and effectiveness were assessed using receiver operating characteristic (ROC) curves, calibration plots and decision curves analysis (DCA). Then the model was subsequently validated on the validation set. RESULTS: The incidence of frailty in BC patients with extended survival was 35.8%. We identified six independent risk factors including age, health status, chemotherapy, endocrine therapy, number of comorbidities and oral medications. Ultimately, we constructed an optimal model (combined model C) for frailty. The predictive model showed significantly high discriminative accuracy in the training set AUC: 0.754, (95% CI, 0.719-0.789; sensitivity: 76.8%, specificity: 62.2%) and validation set AUC: 0.805, (95% CI, 0.76-0.85), sensitivity: 60.8%, specificity: 87.1%) respectively. A prediction nomogram was constructed for the training and validation sets. Calibration and DCA were performed, which indicated that the clinical model presented satisfactory calibration and clinical utility. Ultimately, we implemented the prediction model into a mobile-friendly web application that provides an accurate and individualized prediction for BC. CONCLUSIONS: The present study demonstrated that the prevalence of frailty in BC patients with extended survival was 35.8%. We developed a novel model for screening frailty, which may provide evidence for frailty screening and prevention.

Financial toxicity experienced by patients with breast cancer-related lymphedema: a systematic review.

PURPOSE: To perform a systematic review on financial toxicity of breast cancer-related lymphedema. METHODS: Seven databases were searched on September 11, 2022. Eligible studies were identified, analyzed, and reported following the Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) guidelines. Empirical studies were appraised by the Joanna Briggs Institute (JBI) tools. The Mixed Methods Appraisal Tool version 2018 was used to assess the mixed method studies. RESULTS: A total of 963 articles were identified, but only 7 articles reporting on 6 studies met the eligibility criteria. A 2-year treatment for lymphedema was approximately USD$14,877 to USD$23,167 in America. In Australia, the average out-of-pocket costs ranged from A$207 to A$1400 (USD$156.26 to USD$1056.83) per year. Outpatient visits, compressed clothing, and hospital admissions were the dominant costs. The financial toxicity was associated with the severity of lymphedema, and patients with heavy financial burden had to reduce other expenses or even forgo the treatment. CONCLUSION: Breast cancer-related lymphedema aggravated the economic burden of patients. The included studies showed great variation in the methods used and therefore differences in cost results. The national government should further improve the healthcare system and increase the insurance coverage of lymphedema treatment to alleviate this burden. More research is needed to focus on financial toxicity experience of breast cancer patients with lymphedema. IMPLICATIONS FOR CANCER SURVIVORS: The cost of the ongoing treatment of breast cancer-related lymphedema influences patients' economic situation and quality of life. Survivors need to be informed early about the potential financial burden associated with lymphedema treatment.

Predicting lymphedema self-management behaviours in breast cancer patients: A structural equation model with the Integrated Theory of Health Behaviour Change.

AIMS: To explore predictors of lymphedema self-management behaviours among Chinese breast cancer survivors based on the Integrated Theory of Health Behaviour Change, and to clarify the interrelationship among these variables. DESIGN: Further analysis of a multicentre cross-sectional and survey-based study. METHODS: A total of 586 participants with breast cancer were recruited from December 2021 to April 2022 in different cities in China. We used self-reported questionnaires to collect data. Descriptive analysis, bivariate analysis and structural equation model were performed. RESULTS: The Integrated Theory of Health Behaviour Change is suitable for predicting lymphedema self-management behaviours. The final structural model showed good model fit. Social support, self-efficacy and lymphedema knowledge positively affected lymphedema self-management behaviours, directly and indirectly. Self-regulation acted as a crucial mediator between these variables and self-management. The direct path between social support and self-regulation was not significant. Lymphedema knowledge and social support also influenced self-management via illness perception, self-efficacy and self-regulation, sequentially. These variables explained 55.9% of the variance in lymphedema self-management behaviours. CONCLUSIONS: The modified model based on the Integrated Theory of Health Behaviour Change fitted well in predicting lymphedema self-management behaviours among breast cancer patients. Lymphedema knowledge, illness perception, self-efficacy, social support and self-regulation directly and indirectly influenced lymphedema self-management behaviours. IMPACT: This study provides a theoretical basis for the assessment and interventions of lymphedema self-management behaviours in breast cancer patients. Lymphedema self-management behaviours should be assessed regularly and comprehensively, taking these predictors into consideration to identify potential barriers. Further research is needed to explore effective interventions integrating these significant predictors. REPORTING METHOD: This study was reported following Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist for cross-sectional studies. PATIENT OR PUBLIC CONTRIBUTION: No patient or public contributed to the design or conduct of the study, analysis or interpretation of the data, or in the preparation of the manuscript. WHAT DOES THIS PAPER CONTRIBUTE TO THE WIDER GLOBAL CLINICAL COMMUNITY?: This study focused on identifying and predicting mechanism of self-management based on a theory of behaviour change. The results can be applied among patients with other chronic diseases or high-risk populations, and inspire the assessment and interventions facilitating self-management behaviours. STUDY REGISTRATION: This study was registered as an observational study at Chinese Clinical Trial Registry: http://www.chictr.org.cn (ChiCTR2200057084). IMPLICATIONS FOR THE PROFESSION AND/OR PATIENT CARE: For breast cancer patients with poor lymphedema self-management behaviour, attention should be raised among nurses and involved healthcare staffs that lymphedema self-management is multi-faced. Strategies targeted at improving social support, self-regulation, knowledge, self-efficacy and illness perception should be also addressed in lymphedema self-management programs, to facilitate more effective improvement of lymphedema self-management behaviours.

Factors associated with lymphedema self-management behaviours among breast cancer survivors: A cross-sectional study.

AIMS AND OBJECTIVES: The purpose of this empirical study was to explore the current status and associated factors of lymphedema self-management behaviours among Chinese breast cancer survivors. BACKGROUND: Breast cancer-related lymphedema is a lifetime concern for survivors and is currently incurable. Lifetime lymphedema self-management takes a significant role in preventing development and progression of lymphedema. Understanding influencing factors of lymphedema self-management behaviours can help to develop targeted intervention programs. DESIGN: A multicentre cross-sectional study. METHODS: From December 2021 to April 2022, a convenience sample of 586 participants were recruited at four tertiary hospitals in four cities in China. Self-reported questionnaires were used to measure socio-demographic characteristics, disease-and treatment-related characteristics, lymphedema self-management behaviours, lymphedema knowledge, illness perception, self-efficacy, self-regulation and social support. Descriptive analysis, bivariate analysis and hierarchical multiple regression were conducted. This study was registered at Chinese Clinical Trial Registry (ChiCTR2200057084), and was reported followed the STROBE checklist. RESULTS: Breast cancer survivors reported moderate level of lymphedema self-management behaviours. Promotion of lymph reflux management was ranked the least performed self-management behaviours, while the affected limb protection management ranked the most. 36.2% of self-management behaviours was explained by exercise regularly, level of attention on lymphedema prevention, unclear about the tumour stage (vs. stage I), knowledge, self-efficacy, emotional illness representation and social support. CONCLUSIONS: Lymphedema self-management behaviours of breast cancer survivors was insufficient. Performance of lymphedema self-management varied with different socio-demographic characteristics, along with different levels of knowledge, self-efficacy, perception and social support. All these identified predictors should be reckoned in assessment and intervention of lymphedema self-management behaviours. RELEVANCE TO CLINICAL PRACTICE: This study addressed that breast cancer survivors' lymphedema self-management behaviours should be promoted. Focusing on identified predictors, further lymphedema surveillance, knowledge education or social facilitation programs are recommended to enhance their self-management performance and adherence.

The mediating effect of coping styles between self-compassion and body image disturbance in young breast cancer survivors: a cross-sectional study.

BACKGROUND: Young breast cancer survivors with body image disturbance have poor quality of life. Self-compassion and different coping styles can influence their body image. The purpose of the study was to investigate the relationship between self-compassion, coping styles, and body image disturbance, and examined the mediation role of coping styles between self-compassion and body image disturbance among young breast cancer survivors in China. METHODS: In the cross-sectional study, a total of 310 young women with breast cancer were assessed on self-compassion, coping styles, and body image disturbance by self-reported questionnaires in China. Spearman's correlation was used to test the links between variables and to verify the indirect effects between variables by constructing a structural equation model. RESULTS: There were correlations between self-compassion, different coping styles, and body image disturbance. Confrontation, avoidance, and acceptance-resignation coping had significant mediation effects on the association between self-compassion and body image disturbance. The mediation effects of confrontation coping were greater than avoidance, and acceptance-resignation coping. CONCLUSIONS: In this study, different coping styles acted as mediators between self-compassion and body image disturbance, providing support for further understanding the mechanism between self-compassion and body image disturbance, and developing comprehensive interventions for body image disturbance. Oncology nurses should pay attention to the breast cancer survivors' self-compassion and coping styles and encourage them to adopt adaptive coping strategies, which can reduce body image disturbance.

Benefits of Dietary Management in Breast Cancer Patients: A Systematic Review and Meta-Analysis.

The World Cancer Research Fund/American Institute of Cancer Research recommendations include guidance on diet, nutrition, and weight management for people with cancer. However, for women diagnosed with breast cancer there is a lack of comprehensive analyses on the effects of dietary interventions. The purpose of this study was to investigate the impact of changes in dietary behavior and body composition on breast cancer development. A comprehensive and systematic literature search of 12 electronic databases was undertaken on January 27, 2021 to identify randomized controlled trials (RCTs) of dietary interventions for breast cancer. The Cochrane risk bias assessment tool was used to evaluate the quality of the trials identified with the data analyzed by Review Manager 5.3 software. The results showed that dietary interventions probably did not modify servings of fruit (P = 0.08), fat intake (P = 0.10), total cholesterol level (P = 0.82), body weight (P = 0.08), waist circumference (P = 0.15), or waist-to-hip ratio (P = 0.32). However, a significant reduction in body mass index (P = 0.03), and hip circumference (P = 0.03), and improvement in energy intake (P = 0.02), vegetable servings (P < 0.0001), and fiber intake (P < 0.00001) were observed. Future studies should investigate the benefits of exercise in combination with dietary interventions in breast cancer patients.Supplemental data for this article is available online at https://doi.org/10.1080/01635581.2021.1957129.

Benefits of weight loss programs for breast cancer survivors: a systematic reviews and meta-analysis of randomized controlled trials.

BACKGROUND: Obesity and weight gain have been associated with poor disease-specific and health-related outcomes in breast cancer survivors (BCS). But the benefits of weight loss in managing BCS have not been elucidated. OBJECTIVE: To evaluate the beneficial effects of weight loss programs in randomized controlled trials on BCS. METHODS: We searched English databases PubMed, the Cochrane Library, EMBASE, Scopus, Web of Science, CINAHL, and Chinese databases China National Knowledge Infrastructure (CNKI), Weipu Information Chinese Periodical Service Platform (VIP), China Biomedical Literature Service System (SinoMed), and Wanfang from the inception to January 2021 and collected randomized controlled trials (RCTs) of weight loss programs for BCS. Two reviewers independently screened the literature, extracted the data, and assessed the risk of bias in the included studies. The data synthesis was performed on RevMan (version 5.3), and the publication bias was calculated with STATA (version 15.1). RESULTS: Ten RCTs were included in the meta-analysis. The current study showed that diet and exercise interventions resulted in significant improvements in body weight (MD = - 4.43 kg, 95%CI: - 6.23 to - 2.63, P < 0.00001), waist circumference (MD = - 2.81 cm, 95%CI: - 4.37 to - 1.26, P = 0.004), hip circumference (MD = - 3.01 cm, 95%CI: - 4.24 to - 1.77, P < 0.0001), body mass index (MD = - 1.69 kg/m2, 95%CI: - 2.16 to - 1.21, P < 0.00001), systolic blood pressure (MD = - 12.12 mmHg, 95%CI: - 18.97 to - 5.27), p = 0.0005), C-reactive protein (MD = - 1.83 mg/L, 95% CI: - 2.74 to - 0.91, p < 0.0001), body fat (MD = - 1.19 kg, 95%CI: - 1.75 to - 0.63, P < 0.001), fat mass (MD = - 2.29 kg, 95%CI: - 3.12 to - 1.46, P < 0.0001), and lean body mass (MD = - 2.15 kg, 95%CI: - 3.66 to - 0.65, P = 0.005). Alternatively, compared with the effects of control interventions, weight loss programs did not affect fat-free mass, total cholesterol, low-density leptin cholesterol, glucose, insulin, and leptin (P > 0.05). CONCLUSIONS: This review summarizes the benefits of weight loss programs for BCS. The results indicated that weight loss programs could significantly improve specific anthropometric outcomes but not affect biochemical indicators. Researchers should tailor weight loss interventions to the body fat status of BCS. Evidence to support the translation of effective weight loss intervention programs into wider-scale implementation is needed to be part of routine survivorship care.

What is the appropriate skin cleaning method for nasopharyngeal cancer radiotherapy patients? A randomized controlled trial.

PURPOSE: To determine the effect of various cleaning methods for skin with acute radiation dermatitis (RD) in patients treated for nasopharyngeal carcinoma (NPC). METHODS: A total of 168 NPC inpatients were randomized, while 152 patients completed the whole trial and the data were analyzed. Patients were randomly divided into the non-washing group (Group 1), washing with water alone group (Group 2), and washing with water and soap group (Group 3). All three groups received intensity-modulated radiation therapy (IMRT) with other treatments. Follow-up from recruitment or the initial radiotherapy dose to 1 month after the final radiotherapy dose. CONSORT checklist was applied as the reporting guidelines for this study. The study evaluated a range of endpoints, including incidence, timing, severity of acute RD, and quality of life (QOL). RESULTS: There were no allergic reactions or aggravating in both washing groups during the whole treatment. The incidence of acute RD was 100% in all three groups, while the incidence of severe RD (grades 2-3) differed among groups (Group 1 vs. Group 2 vs. Group 3: 51% vs. 23.5% vs. 18%; P = 0.001), washing moderately reduced severity compared with patients without washing. Washing also delayed the onset time of acute RD; the incidence of acute RD was significantly lower than non-washing during the first 20 fractions (P < 0.001). What is more, washing reduced the incidence of moist desquamation (25.5% vs. 5.9% vs. 6%; P = 0.003) and helped relieve itching (6.49 ± 2.09 vs. 4.90 ± 1.90 vs. 4.00 ± 1.58; P < 0.001). There were no significant differences among groups with respect to pain or burning sensation. Washing improved QOL on physical (64.37 ± 4.08 vs. 67.41 ± 4.05 vs. 71.30 ± 4.87; P < 0.001), emotional (61.47 ± 4.75 vs. 65.75 ± 3.46 vs. 70.80 ± 3.27; P < 0.001), and social functional dimensions (62.64 ± 3.57 vs. 64.87 ± 3.88 vs. 68.04 ± 4.89; P < 0.001) at the end of radiotherapy, and the outcome was similar at 1 month after radiotherapy (P < 0.05). Washing with water and soap was the most effective way to reduce itching and improving QOL among the three groups (P < 0.05). CONCLUSION: Washing irradiated skin reduces the occurrence and severity of acute radiation dermatitis. CLINICAL TRIAL INFORMATION: ChiCTR2000038231, date of registration 09.18.2020.

Risk factors of unilateral breast cancer-related lymphedema: an updated systematic review and meta-analysis of 84 cohort studies.

PURPOSE: To review and update the incidence and risk factors for breast cancer-related lymphedema based on cohort studies. METHODS: The study was guided by the Joanna Briggs Institute methodology and the Cochrane handbook for systematic reviews. PubMed, EMBASE, CINAHL, Scopus, Web of Science, The Cochrane Library, CNKI, SinoMed, and Wan Fang Database were searched from inception to November 15, 2021. Cohort studies reported adjusted risk factors were selected. PRISMA guideline was followed. Study quality were evaluated using the Newcastle-Ottawa scale. Random-effects models were adopted. The robustness of pooled estimates was validated by meta-regression and subgroup analysis. Lymphedema incidence and adjusted risk factors in the multivariable analyses with hazard / odds ratios and 95% CIs were recorded. RESULTS: Eighty-four cohort studies involving 58,358 breast cancer patients were included. The pooled incidence of lymphedema was 21.9% (95% CI, 19.8-24.0%). Fourteen factors were identified including ethnicity (black vs. white), higher body mass index, higher weight increase, hypertension, higher cancer stage (III vs. I-II), larger tumor size, mastectomy (vs. breast conservation surgery), axillary lymph nodes dissection, more lymph nodes dissected, higher level of lymph nodes dissection, chemotherapy, radiotherapy, surgery complications, and higher relative volume increase postoperatively. Additionally, breast reconstruction surgery, and adequate finance were found to play a protective role. However, other variables such as age, number of positive lymph nodes, and exercise were not correlated with risk of lymphedema. CONCLUSION: Treatment-related factors still leading the development of breast cancer-related lymphedema. Other factors such as postoperative weight increase and finance status also play a part. Our findings suggest the need to shift the focus from treatment-related factors to modifiable psycho-social-behavioral factors.

The prevalence of frailty among breast cancer patients: a systematic review and meta-analysis.

PURPOSE: Coexistence of frailty and breast cancer (BC) is related to a higher risk of hospitalization, mortality, and falls. Given the potential reversibility of frailty, investigating its epidemiology in BC is of great importance. However, estimates of the prevalence of frailty in BC patients vary considerably. We synthesized the existing body of literature on the prevalence of frailty among BC patients. METHODS: We searched English databases (Cochrane Library, PubMed, Medline, CINAHL, Embase, Scopus, and Web of Science) and Chinese databases (CNKI, WanFang, CBM, and VIP database) from the inception to April 15, 2021, and collected observational studies about the prevalence of frailty among BC patients. The robustness of the pooled estimates was validated by analysis of different subgroups, meta-regression, and sensitivity. All data were analyzed using Stata 15.1. RESULTS: In total, 4645 articles were screened and data from 24 studies involving 13,510 subjects were used in the meta-analysis. The prevalence of frailty among BC patients in individual studies varied from 5 to 71%. The pooled prevalence of frailty was 43% (95% confidence intervals (CI): 36% to 50%, I2 = 98.4%, P < 0.05). Subgroup analyses revealed that the therapeutic method, frailty scales, age, frailty stage, regions, publication years, and study quality were associated with the prevalence of frailty among BC patients. CONCLUSIONS: The prevalence of frailty among BC patients was relatively high, and the conditions of BC treatment can increase the risk of frailty. Understanding the effects of frailty on BC, especially in elderly patients, can provide the healthcare personnel with the theoretical basis for patients' management and treatment.

The scalp cooling therapy for hair loss in breast cancer patients undergoing chemotherapy: a systematic review and meta-analysis.

PURPOSE: To systematically assess the efficacy and side effects of scalp cooling in patients with breast cancer. METHODS: A systematic literature search was conducted in October 2020 across Cochrane Library, PubMed, Embase, CINAHL, Web of Science, Scopus, and four Chinese databases (CNKI, Wanfang, SinoMed, and VIP database). Our review included all randomized controlled trials, cohort studies, and cross-sectional studies. Two authors independently searched databases, screened studies, extracted data, and evaluated each included study's methodological quality and risk bias. Meta-analysis was performed using Stata 15.1 software package and Revman 5.3 software, with estimates of scalp cooling effect and its side effects from pooled using a random-effects model. This study has been registered in the International Prospective Register of Systematic Reviews (PROSPERO, CRD42020216224). RESULTS: In total, 755 articles were screened and data from 27 studies involving 2202 participants were used in the meta-analysis. Studies meeting inclusion and exclusion criteria were three randomized clinical trials, 12 cohort studies, and 12 cross-sectional studies. The effectiveness rate of using a scalp cooling device to protect hair was 61% (95% CI: 55 to 67%, I2 = 88%, P = 0.000). However, scalp cooling therapy's side effects are not be ignored, such as headache, dizziness, scalp pain, neck pain, feeling cold, heaviness of the head, skin rash, nausea, and overtightened strap. CONCLUSIONS: This review shows that scalp cooling devices can significantly improve the patients with breast cancer chemotherapy-induced alopecia, but the implications of its side effects provide guide for the implementation of this technology.

Development and validation of a risk assessment nomogram for venous thromboembolism associated with hospitalized postoperative Chinese breast cancer patients.

AIM: The purpose of this study was to develop and validate an individualized nomogram to predict venous thromboembolism (VTE) risk in hospitalized postoperative breast cancer patients. DESIGN: A single-central retrospective and non-interventional trial. METHODS: For model development, we used data from 4,755 breast cancer patients between 1 November 2016-30 June 2018 (3,310 patients in the development group and 1,445 in the validation group). Overall, 216 patients developed VTE (150 in development group and 66 in validation group). The model was validated by receiver operating characteristic curves and the calibration plot. The clinical utility of the model was determined through decision curve analysis. RESULTS: The individualized nomogram consisted of six clinical factors: age, body mass index, number of cardiovascular comorbidities, neoadjuvant chemotherapy, surgical treatment, hospital length of stay and two pre-operative biomarkers of Homocysteine and D-dimer. The model at the 3.9% optimal cut-off had the area under the curve of 0.854 (95% CI, 0.824-0.884) and 0.805 (95% CI, 0.740-0.870) in the development and validation groups. A p = 0.570 of the calibration test showed that the model was well-calibrated. The net benefit of the model was better between threshold probabilities of 5%-30% in decision curve analysis. CONCLUSION: The nomogram of VTE risk assessment, is applicable to hospitalized postoperative breast cancer patients. However, multi-central prospective studies are needed to improve and validate the model. Effectiveness and safety of thromboprophylaxis in high-risk patients are needed to demonstrate in interventional trials. IMPACT: This nomogram can be used in clinical to inform practice of physicians and nurses to predict the VTE probability and maybe direct personalized decision making for thromboprophylaxis in hospitalized postoperative breast cancer patients.

The effects of dietary advice on malnutrition in Cancer patients: a systematic review and meta-analysis.

BACKGROUND: The effect of dietary advice on malnutrition in cancer patients is unclear. The aim of this systematic review was to evaluate the effects of dietary advice in cancer patients who were malnourished or at risk of malnutrition. METHODS: Seven electronic databases were searched for randomized controlled trials (RCTs) of dietary counseling intervention in cancer patients with malnutrition or at risk of malnutrition. The studies were selected according to the inclusion and exclusion criteria and were critically appraised and abstracted by two researchers individually. Effect sizes were presented as weighted mean differences (WMD) or risk ratio (RR) with 95% confidence intervals (95%CI). RESULTS: Six RCTs (737 participants) were included in meta-analysis. Comparing to usual care, dietary advice given by dieticians could not reduce mortality (RR = 1.11, 95%CI = 0.95 to 1.29) and body weight (WMD = 4.28 kg, 95%CI = - 0.21 to 8.76 kg) in cancer patients who were malnourished or at risk of malnutrition, but it was associated with statistically significant improvements in energy intake (WMD = 230.23kCal, 95%CI: 171.49 to 288.98), and quality of life (WMD = 37.92, 95%CI: 23.14 to 52.70). CONCLUSIONS: There remains insufficient evidence to conclude the actual effect of dietary advice given by dieticians in malnourished patients with cancer. Meta-analysis suggested that dietary advice given by dietitians may have no effect on mortality and body weight in patients with cancer who are malnourished, but it may be effective for improving QoL and energy intake. Studies with adequate participants and a clear low risk of bias are required to improve accuracy and confidence of conclusions.

Music interventions for chemotherapy-induced nausea and vomiting: a systematic review and meta-analysis.

BACKGROUND: Chemotherapy-induced nausea and vomiting (CINV) is the most common and severe side effects brought by chemotherapeutics. The role of music interventions in relieving CINV is uncertain. The aim of this systematic review was to test the effects of music interventions on three categories of CINV. METHODS: A systematic search was conducted in Cochrane Central Register of Controlled Trials (CENTRAL), Cumulative Index to Nursing and Allied Health Literature (CINAHL), PubMed, EMBASE, China National Knowledge Infrastructure (CNKI), WanFang, and Chinese Biomedical Database (CBM) in order to capture randomized controlled trials (RCTs) investigating the comparative efficacy of music interventions and others. Two investigators screened, sorted, and extracted the data, and appraised the risk of bias. All statistical analyses were performed using RevMan 5.3 software. RESULTS: The literature search yielded 608 studies of which only ten RCTs fulfilled the eligibility criteria with 632 patients retrieved. Although the duration, the frequency of interventions, and the type of selected music varied across studies, commonly used elements included music listening. Results showed that music interventions were associated with reducing the incidence of anticipatory CINV and lowering the severity of delayed vomiting (MD = - 0.65, 95% CI = - 1.08 to - 0.23). However, strongly controversial results existed in terms of reducing the incidence of acute and delayed CINV, the severity of acute CINV, the severity of delayed nausea, and improving patients' quality of life. CONCLUSIONS: Music interventions may effectively reduce the incidence of anticipatory CINV and relieve the severity of delayed vomiting in patients with chemotherapy based on limited data. However, the conclusion should be interpreted with caution and further research is required to design with large-scale and rigorous methods.

A technical appraisal of guidelines for the management of skin rash in patients on chemotherapy and targeted therapy.

BACKGROUND: Skin rash remains one of the most prevalent and troublesome clinical problems experienced by patients on chemotherapy and targeted therapy. To ensure high-quality care, guidelines are seen as the best guidance. Considering the quality of guidelines varies greatly, a systematical appraisal of the methodological quality of guidelines for the management of skin rash in patients on chemotherapeutic drugs and targeted anticancer therapies was undertaken, in order to identify appropriate ones for healthcare professionals. METHODS: A systematic search of databases and Internet was conducted to obtain pertinent guidelines. Two reviewers independently assessed the eligibility of guidelines according to the inclusion criteria. Then the guidelines included were appraised by three researchers with the methodological quality of eligible guideline using Appraisal of Guidelines for Research and Evaluation II (AGREEII). RESULTS: Totally nineteen guidelines met the inclusion criteria. The quality ranged from good to acceptable in scope and purpose (mean: 78.80%, range: 66.67-94.44%) and clarity of presentation domains (mean: 85.38%, 75.00-91.67%), but not in stakeholder involvement (mean: 50.15%, range: 36.11-75.00%), rigor of development (mean: 23.65%, range: 6.25-70.83%), applicability (mean: 23.96%, range: 4.17-52.08%), and editorial independence domains (mean: 45.18%, range: 0.00-87.50%). Overall, two guidelines were classified as "recommended". CONCLUSIONS: Only two guidelines were recommended to manage skin rash in patients on chemotherapy and targeted therapies, most guidelines issued were of low to moderate quality. Thus, more attention should be paid to the methodological quality of guideline development in this field.

The management strategies of cancer-associated anorexia: a critical appraisal of systematic reviews.

BACKGROUND: Cancer-related anorexia remains one of the most prevalent and troublesome clinical problems experienced by patients with cancer during and after therapy. To ensure high-quality care, systematic reviews (SRs) are seen as the best guide. Considering the methodology quality of SRs varies, we undertook a comprehensive overview, and critical appraisal of pertinent SRs. METHODS: Eight databases (between the inception of each database and September 1, 2017) were searched for SRs on the management of cancer-related anorexia. Two researchers evaluated the methodological quality of each SR by using the Revised Assessment of Multiple Systematic Reviews (R-AMSTAR) checklist. Characteristics of the "high quality" SRs were abstracted, included information on relevant studies numbers, study design, population, intervention, control, outcome and result. RESULTS: Eighteen SRs met the inclusion criteria. The R-AMSTAR scores of methodological quality ranged from 18 to 41 out of 44, with an average score of 30. Totally eight SRs scored ≥31 points, which showed high methodological quality, and would be used for data extraction to make summaries. Anamorelin had some positive effects to relieve cancer anorexia-cachexia syndrome (CACS) and improve the quality of life (QoL). Megestrol Acetate (MA) could improve appetite, and was associated with slight weight gain for CACS. Oral nutritional interventions were effective in increasing nutritional intake and improving some aspects of QoL in patients with cancer who were malnourished or at nutritional risk. The use of thalidomide, Eicosapentaenoic Acid, and minerals, vitamins, proteins, or other supplements for the treatment of cachexia in cancer were uncertain, and there was inadequate evidence to recommend it to clinical practices, the same situation in Chinese Herb Medicine and acupuncture (acupuncture and related therapies were effective in improving QoL) for treating anorexia in cancer patients, warranting further RCTs in these areas. CONCLUSIONS: Anamorelin, MA, oral nutrition interventions, and acupuncture could be considered to be applied in patients with cancer-related anorexia. Future RCTs and SRs with high quality on the pharmaceutical or non-pharmaceutical interventions of anorexia in cancer patients are warranted.

Factors Influencing the Self-management of Breast Cancer-Related Lymphedema: A Meta-synthesis of Qualitative Studies.

BACKGROUND: Patients with breast cancer have an estimated 14% to 60% risk of developing lymphedema after treatment. Self-management behavior strategies regarding lymphedema are essential in preventing and alleviating the severity of lymphedema. OBJECTIVE: The aim of this study was to evaluate qualitative research evidence on the potential influencing factors for self-management behaviors of lymphedema in patients with breast cancer. METHODS: A systematic search of 10 electronic databases was conducted to identify qualitative studies on patient experience of lymphedema self-management. The following databases were included and appraised using the Joanna Briggs Institute Critical Appraisal Checklist: Cochrane Library, PubMed, EMBASE, Web of Science, PsycINFO, Scopus, Cumulative Index to Nursing and Allied Health Literature, China National Knowledge Infrastructure, Wanfang Med Online, and Chinese Biomedical Database. RESULTS: The literature search yielded 5313 studies, of which only 22 qualitative studies fulfilled the eligibility criteria. Five synthesized findings were derived encompassing personal characteristics, personal knowledge and experience, personal health beliefs, self-regulation skills and abilities, and social influences and support. CONCLUSIONS: Patients with breast cancer are confronted with many challenges when performing self-management of lymphedema. Therefore, it is important to recognize potential facilitators and barriers to further offer practical recommendations that promote self-management activities for lymphedema. IMPLICATIONS FOR PRACTICE: Healthcare professionals should receive consistent training on lymphedema management. On the basis of individual patient characteristics, tailored education and support should be provided, including transforming irrational beliefs, and improving related knowledge and skills, with the aim to promote self-management behaviors with respect to lymphedema.

Association of self-compassion and body image disturbance among young breast cancer patients: Mediating effect of body surveillance and body shame.

Objective: To examine whether body surveillance and body shame mediated the association between self-compassion and body image disturbance among young breast cancer patients. Methods: In this cross-sectional descriptive study, a total of 310 young women with breast cancer were recruited by convenience sampling. All of them completed self-report measurements of demographic and clinical characteristics, self-compassion scale, body image self-rating questionnaire for breast cancer and body surveillance scale, and body shame scale between September and December 2021 â€‹at a tertiary cancer hospital in Tianjin, China. Data analysis was performed with correlation analysis and structural equation modeling to verify relationships between key variables. Results: Less self-compassion was significantly associated with greater body image disturbance, while a positive correlation was found between body image disturbance, body surveillance, and body shame. Self-compassion indirectly negative predicted body image disturbance via the chain mediation of body surveillance and body shame. Conclusions: The links of self-compassion and body image disturbance were mediated by body surveillance and body shame. Reducing patients' excessive body surveillance and body shame by improving their ability of self-compassion may be an effective measure to reduce body image disturbance.
