A longitudinal study of depression, fatigue, and sleep disturbances as a symptom cluster in women with breast cancer

Associations between health-related fitness and patient-reported symptoms in newly diagnosed breast cancer patients

BACKGROUND

Newly diagnosed breast cancer patients experience symptoms that may affect their quality of life, treatment outcomes, and survival. Preventing and managing breast cancer-related symptoms soon after diagnosis is essential. The purpose of this study was to investigate the associations between health-related fitness (HRF) and patient-reported symptoms in newly diagnosed breast cancer patients.

METHODS

This study utilized baseline data from the Alberta Moving Beyond Breast Cancer Cohort Study that were collected within 90 days of diagnosis. HRF measures included peak cardiopulmonary fitness (peak volume of oxygen consumption (VO2peak)), maximal muscular strength and endurance, flexibility, and body composition. Symptom measures included depression, sleep quality, and fatigue. Adjusted multivariable logistic regression was performed for analyses.

RESULTS

Of 1458 participants, 51.5% reported poor sleep quality, 26.5% reported significant fatigue, and 10.4% reported moderate depression. In multivariable-adjusted models, lower relative VO2peak was independently associated with a greater likelihood of all symptom measures, including moderate depression (p < 0.001), poor sleep quality (p = 0.009), significant fatigue (p = 0.008), any symptom (p < 0.001), and multiple symptoms (p < 0.001). VO2peak demonstrated threshold associations with all symptom measures such that all 3 lower quartiles exhibited similar elevated risk compared to the highest quartile. The strength of the threshold associations varied by the symptom measure with odds ratios ranging from ∼1.5 for poor sleep quality to ∼3.0 for moderate depression and multiple symptoms. Moreover, lower relative upper body muscular endurance was also independently associated with fatigue in a dose-response manner (p = 0.001), and higher body weight was independently associated with poor sleep quality in an inverted U pattern (p = 0.021).

CONCLUSION

Relative VO2peak appears to be a critical HRF component associated with multiple patient-reported symptoms in newly diagnosed breast cancer patients. Other HRF parameters may also be important for specific symptoms. Exercise interventions targeting different HRF components may help newly diagnosed breast cancer patients manage specific symptoms and improve outcomes.

Identifying symptom cluster in cancer patients undergoing chemotherapy-in Vietnam: A cross-sectional study

BACKGROUND

Major cancer treatments can cause a wide range of unpleasant symptoms that burden oncology patients. Different symptom clusters (SC) among cancer patients have been reported in the literature. This study determined the prevalence of symptoms patients experience during chemotherapy treatment and identified symptom clusters among them.

METHODS

A cross-sectional study was conducted among 213 cancer patients undergoing chemotherapy in three large hospitals in Vietnam. Symptoms were measured by the Memorial Symptom Assessment Scale.

RESULTS

The most prevalent symptoms were lack of appetite (65.3%), difficulty sleeping (62.9%), dry mouth (57.7%), numbness (60.1%), hair loss (43.2%), change in the way food tastes (40.8%), and lack of energy (44.1%). Four symptom clusters were identified. Difficult concentration, pain, cough, and dizziness contributed to the first SC. The second one included lack of energy, numbness, change the food taste, and lack of appetite. Dry mouth, nausea, feeling bloated, problems with urination, hair loss, and constipation made up for the third SC. The final SC consisted of psychological symptoms, which were feeling nervous, feeling drowsy, feeling sad, worrying, problems with sexual interest or activity and difficulty sleeping.

CONCLUSION

The study demonstrated that respondents experienced various symptoms and symptom clusters during chemotherapy. These findings can be used to develop clinical guidelines for symptom assessment and management in oncology patients for healthcare professionals.

Fatigue and related variables in bladder cancer treatment - Longitudinal pilot study

Fatigue is a significant problem in patients with bladder cancer treated by radical cystectomy. This pilot study evaluated fatigue and related variables during a treatment period. Four measurements were made, the first 1 month after the cystectomy, and the next three at an interval of about 3 months each (at 4 months, 7 months, and 10 months after the surgery). In addition to the author's questionnaire (sociodemographic variables and a question about the impact of the disease on the patient's life), the FACIT-F Fatigue (to measure fatigue), NCCN/FACT FBISI-18, version 2 (symptoms, general condition of the patient), HADS (depression, anxiety, and irritability) measures were used. In this study, 21 patients participated in all four measurement periods. The fatigue intensity increased significantly between the first and second measurements and gradually decreased between the third and fourth measurements. As the severity of fatigue increases, can be observed an increase in the sense of the impact of the disease on the patient's life in all except the first measurement. The study revealed statistically significant correlations between fatigue and experiencing symptoms of cancer and treatment at each stage of the study, with the strongest correlations in the second and fourth measurements regarding symptoms of cancer and a stronger correlation in the second compared to the first measurement regarding side effects. At each stage of measurement, the experience of dizziness, lack of appetite, feeling of being sick, and feeling of annoyance from treatment side effects were statistically significantly correlated with fatigue. The intensity of fatigue correlated with the feeling of experiencing difficulties in meeting the needs of the family due to the physical condition in the first measurement (Rho = 0.76), a sense of weakness (Rho = 0.92) and sleepiness (Rho = 0.72) in the second measurement, pain in the third (Rho = 0.77). The greatest number of correlates of fatigue were described in the fourth measurement (all symptoms of cancer and side effects except losing weight). Stress, anxiety, depression and irritability were correlated with fatigue at each of the stages of research except the first one (without differences between the correlation coefficients in the second, third and fourth measurements). Significantly lower levels of fatigue characterised patients who survived over 6 months after the end of the study compared to the first three measurements.

Effects of a tailor-made yoga program on upper limb function and sleep quality in women with breast cancer: A pilot randomized controlled trial

Purpose

Upper limb dysfunction and sleep disturbance are common and serious health problems in women with breast cancer. Yoga is a mind-body intervention which is shown to improve physical and psychological health. The aim of this study is to evaluate the effectiveness of a tailor-made yoga program on upper limb function and sleep quality in women with breast cancer.

Methods

A pilot randomized controlled trial (RCT) study design was used. Participants were randomly allocated to either the yoga intervention group (YG; eight weekly 60-min group-based yoga sessions) or the wait-list control group (CG). The primary outcome measures were upper limb function and sleep quality, which were assessed by the self-reported questionnaires - the shortened version of the Disabilities of the Arm, Shoulder and Hand (QuickDASH) and the Pittsburgh Sleep Quality Index (PSQI), respectively. The secondary outcome measures were upper limb muscle strength and mobility, heart rate variability (HRV), anxiety and depression, fatigue, and health-related quality of life. All participants underwent assessment at four time-points (baseline, mid-intervention, post-intervention, and 1-month follow-up). The effectiveness of the intervention was tested by two-way mixed-design repeated-measures analysis of covariance.

Results

For the primary outcomes, there was no significant between-group difference in the upper limb function. The YG demonstrated significantly shorter sleep latency and higher HRV, and less sleep disturbance than the CG at post-intervention, and 1-month follow-up, respectively. For the secondary outcomes, the YG demonstrated significantly improved shoulder muscle strength and arm symptoms compared to the CG from mid-intervention until the 1-month follow-up.

Conclusion

This pilot trial revealed that the yoga program was feasible to be implemented for women with primary stage breast cancer. Although yoga was not found to be effective in improving the upper limb function, it improved sleep latency, HRV, shoulder muscle strength and arm symptoms of women with breast cancer.

Diurnal and Daily Symptom Variation in Patients with End Stage Kidney Disease: An Ecological Momentary Assessment Study

Key Points

Background

Patients with ESKD on hemodialysis experience a high symptom burden, which is compounded by unpredictable fluctuations in symptom severity. Few studies have used ecological momentary assessment to determine how symptoms vary over time. This study aimed to characterize the diurnal and day-to-day variability in symptoms among patients receiving hemodialysis.

Methods

Patients enrolled in the Technology-Assisted Collaborative Care trial rated the intensity of physical, cognitive, and mood symptoms using an automated telephone-administered version of the Daytime Insomnia Symptom Scale at four time points (morning, early afternoon, late afternoon, evening) for seven consecutive days at baseline. Confirmatory factor analysis was used to verify the original four-factor solution for the Daytime Insomnia Symptom Scale: sleepiness/fatigue (SF), alert cognition (AC), positive mood (PM), and negative mood (NM). Symptom domain scores were calculated for each time point, and mixed modeling with random patient effects was used to examine differences in daily symptoms at daily time points between hemodialysis and non-hemodialysis days after controlling for age, sex, race, and comorbidity burden.

Results

One hundred sixty patients were enrolled (mean±SD age 58±14 years, 45% women, 52% White). Diurnal symptom variation existed; trends were nonlinear and differed by hemodialysis versus non-hemodialysis days. Day-to-day symptom variation also existed; patients endorsed better physical, cognitive, and mood states (i.e., higher AC and PM) as well as lower symptom burden (i.e., lower SF and NM) on non-hemodialysis days compared with hemodialysis days at all time points. The greatest day-to-day mean differences (MDs) were observed in the early afternoon for all symptom domains: AC (MD=0.17 P < 0.001), PM (MD=0.28, P < 0.001), SF (MD=−0.66, P < 0.001), and NM (MD=−0.26, P < 0.001).

Conclusions

Patients with ESKD demonstrate diurnal variation in symptoms and greater symptom burden on hemodialysis days compared with non-hemodialysis days, with the most extreme differences in symptom severity occurring in the early afternoon.

Symptom cluster study undergoing chemotherapy in breast cancer patients: Latent class analysis and contemporaneous network analysis

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.

Effects of sleep disturbance, cancer-related fatigue, and psychological distress on breast cancer patients' quality of life: a prospective longitudinal observational study

More attention has gone to researching the cancer-related fatigue (CRF)-sleep disturbance (SD)-psychological distress (PD) symptom cluster in breast cancer patients during the chemotherapy period, but the change trend and heterogeneous development track in the whole treatment stage remain unclear, and it is also unclear whether the appearance of and changes in one symptom cause changes in other symptoms and quality of life (QoL). This study, using breast cancer patients' data collected through a validated questionnaire, examined the relationships between SD, CRF, PD, and QoL using latent growth modeling analyses. CRF developmental trajectories showed an upward trend over five surveys (slope = 0.649, P < 0.001); PD showed a significant weakening trend (slope = - 0.583, P < 0.001); SD showed an increasing trend (slope = 0.345, P < 0.001), and QoL showed a statistically significant weakening trend (slope = - 0.373, P < 0.001). The initial CRF (coefficient = - 0.233, P < 0.01), PD (coefficient = - 0.296, P < 0.01), and SD (coefficient = - 0.388, P < 0.001) levels had a statistically significant negative effect on initial QoL level. The linear development rate of PD was statistically significant and negatively affected that of QoL (coefficient = - 0.305, P < 0.05), whereas the quadratic development rate of SD negatively affected that of QoL (coefficient = - 0.391, P < 0.05). Medical staff should identify the change characteristics of different variables based on SD, CRF, PD, and QoL change trajectories, and advance the intervention time, as changes in variables affect other variables' subsequent changes.

Effects of nonpharmacological interventions on symptom clusters in breast cancer survivors: A systematic review of randomized controlled trials

Objective

To summarize nonpharmacological interventions and assess their effects on symptom clusters and quality of life (QoL) in breast cancer (BC) survivors.

Methods

Seven English and three Chinese electronic databases and three clinical trial registries were searched from January 2001 to August 2023. A narrative approach was applied to summarize the data. The primary outcome was symptom clusters measured by any patient-reported questionnaires, and the secondary outcomes were QoL and intervention-related adverse events.

Results

Six published articles, one thesis, and one ongoing trial involving 625 BC survivors were included. The fatigue-sleep disturbance-depression symptom cluster was the most frequently reported symptom cluster among BC survivors. The nonpharmacological interventions were potentially positive on symptom clusters and QoL among the BC survivors. However, some of the included studies exhibited methodological concerns (e.g., inadequate blinding and allocation concealment). The intervention protocols in only two studies were developed following a solid evidence-based approach. Adverse events related to the targeted interventions were reported in six included studies, with none performing a causality analysis.

Conclusions

The nonpharmacological interventions could be promising strategies for alleviating symptom clusters in BC survivors. Future studies should adopt rigorously designed, randomized controlled trials to generate robust evidence.

Exploring symptom clusters in mild cognitive impairment and dementia with the NIH Toolbox

OBJECTIVE

Symptom clustering research provides a unique opportunity for understanding complex medical conditions. The objective of this study was to apply a variable-centered analytic approach to understand how symptoms may cluster together, within and across domains of functioning in mild cognitive impairment (MCI) and dementia, to better understand these conditions and potential etiological, prevention, and intervention considerations.

METHOD

Cognitive, motor, sensory, emotional, and social measures from the NIH Toolbox were analyzed using exploratory factor analysis (EFA) from a dataset of 165 individuals with a research diagnosis of either amnestic MCI or dementia of the Alzheimer's type.

RESULTS

The six-factor EFA solution described here primarily replicated the intended structure of the NIH Toolbox with a few deviations, notably sensory and motor scores loading onto factors with measures of cognition, emotional, and social health. These findings suggest the presence of cross-domain symptom clusters in these populations. In particular, negative affect, stress, loneliness, and pain formed one unique symptom cluster that bridged the NIH Toolbox domains of physical, social, and emotional health. Olfaction and dexterity formed a second unique cluster with measures of executive functioning, working memory, episodic memory, and processing speed. A third novel cluster was detected for mobility, strength, and vision, which was considered to reflect a physical functioning factor. Somewhat unexpectedly, the hearing test included did not load strongly onto any factor.

CONCLUSION

This research presents a preliminary effort to detect symptom clusters in amnestic MCI and dementia using an existing dataset of outcome measures from the NIH Toolbox.

Relationship of cancer-related fatigue with psychoneurophysiological (PNP) symptoms in breast cancer survivors

PURPOSE

Cancer-related fatigue (CRF) is a highly prevalent and debilitating symptom reported by breast cancer survivors (BCS). CRF has been associated with the co-occurrence of anxiety, depression, poor sleep quality, cognitive impairment, which are collectively termed as psychoneurophysiological (PNP) symptoms. CRF and these PNP symptoms are often reported during and after treatment with long-lasting distress. It is unclear how CRF and these PNP symptoms influence each other. This study aimed to explore predictive factors (i.e., PNP symptoms and social-demographic factors) of CRF, and test exploratory path models of the relationships of CRF with PNP symptoms (depression, anxiety, sleep disturbance, pain, and cognitive function) in BCS.

METHODS

This paper is part of a larger descriptive, correlational, and cross-sectional study. Validated and reliable instruments assessed CRF, depression, anxiety, sleep disturbance, pain, and cognitive function. Descriptive statistics, Pearson correlation, multiple linear regression models, and path analysis were employed.

RESULTS

Patients (N = 373) who reported less bodily pain had worst CRF (r = -0.45, p < .01). Significant predictors of CRF included depression, sleep disorder, bodily pain, perceived cognitive ability, and dispositional (state) optimism. Depression alone accounted for 31% of the variance in CRF. An integrative path model with bodily pain, neuropathic pain, CRF, and depression showed a good fit across different indices (CFI = 0.993, RMSEA = 0.047, 90% CI 0-0.12, SRMR = 0.027).

CONCLUSIONS

This study identified significant predictors of CRF and revealed a good fit mediation model with significant pathways for CRF, suggesting that a common etiology may underpin the co-occurrence of CRF with PNP symptoms (pain and depression). However, further investigation with longitudinal design is necessary to explore the causal relationships of these symptoms. Evidence-based strategies/interventions are needed to reduce or eliminate the burden of these symptoms on the lives of BCS.

Exploring Guolin Qigong (Mind-Body Exercise) for Improving Cancer Related Fatigue in Cancer Survivors: A Mixed Method Randomized Controlled Trial Protocol

BACKGROUND

Cancer-related fatigue and its associated symptoms of sleep disorder and depression are prevalent in cancer survivors especially among breast, lung, and colorectal cancer survivors. While there is no gold standard for treating cancer-related fatigue currently, studies of mind-body exercises such as Qigong have reported promise in reducing symptoms. This study was designed to evaluate the feasibility and effect of Guolin Qigong on cancer-related fatigue and other symptoms in breast, lung and colorectal cancer survivors while exploring their perceptions and experiences of Guolin Qigong intervention.

METHODS

This is an open-label randomized controlled trial with 60 participants divided into 2 study groups in a 1:1 ratio. The intervention group will receive 12 weeks of Guolin Qigong intervention with a 4-week follow-up while control will receive usual care under waitlist. The primary outcome will be feasibility measured based on recruitment and retention rates, class attendance, home practice adherence, nature, and quantum of missing data as well as safety. The secondary subjective outcomes of fatigue, sleep quality and depression will be measured at Week-1 (baseline), Week-6 (mid-intervention), Week-12 (post-intervention), and Week-16 (4 weeks post-intervention) while an objective 24-hour urine cortisol will be measured at Week-1 (baseline) and Week-12 (post-intervention). We will conduct a semi-structured interview individually with participants within 3 months after Week-16 (4 weeks post-intervention) to obtain a more comprehensive view of practice adherence.

DISCUSSION

This is the first mixed-method study to investigate the feasibility and effect of Guolin Qigong on breast, lung, and colorectal cancer survivors to provide a comprehensive understanding of Guolin Qigong's intervention impact and participants' perspectives. The interdisciplinary collaboration between Western Medicine and Chinese Medicine expertise of this study ensures robust study design, enhanced participant care, rigorous data analysis, and meaningful interpretation of results. This innovative research contributes to the field of oncology and may guide future evidence-based mind-body interventions to improve cancer survivorship.

TRIAL REGISTRATION

This study has been registered with ANZCTR (ACTRN12622000688785p), was approved by Medical Research Ethic Committee of University Malaya Medical Centre (MREC ID NO: 2022323-11092) and recognized by Western Sydney University Human Research Ethics Committee (RH15124).

(Pre)treatment risk factors for late fatigue and fatigue trajectories following radiotherapy for breast cancer

Fatigue is common in breast-cancer survivors. Our study assessed fatigue longitudinally in breast cancer patients receiving adjuvant radiotherapy (RT) and aimed to identify risk factors associated with long-term fatigue and underlying fatigue trajectories. Fatigue was measured in a prospective multicenter cohort (REQUITE) using the Multidimensional Fatigue Inventory (MFI-20) and analyzed using mixed models. Multivariable logistic models identified factors associated with fatigue dimensions at 2 years post-RT and latent class growth analysis identified individual fatigue trajectories. A total of 1443, 1302, 1203 and 1098 patients completed the MFI-20 at baseline, end of RT, after 1 and 2 years. Overall, levels of fatigue significantly increased from baseline to end of RT for all fatigue dimensions (P < .05) and returned to baseline levels after 2 years. A quarter of patients were assigned to latent trajectory high (23.7%) and moderate (24.8%) fatigue classes, while 46.3% and 5.2% to the low and decreasing fatigue classes, respectively. Factors associated with multiple fatigue dimensions at 2 years include age, BMI, global health status, insomnia, pain, dyspnea and depression. Fatigue present at baseline was consistently associated with all five MFI-20 fatigue dimensions (ORGeneralFatigue  = 3.81, P < .001). From latent trajectory analysis, patients with a combination of factors such as pain, insomnia, depression, younger age and endocrine therapy had a particularly high risk of developing early and persistent high fatigue years after treatment. Our results confirmed the multidimensional nature of fatigue and will help clinicians identify breast cancer patients at higher risk of having persistent/late fatigue so that tailored interventions can be delivered.

Associations of Health-Related Quality of Life and Sleep Disturbance With Cardiovascular Disease Risk in Postmenopausal Breast Cancer Survivors

BACKGROUND

Breast cancer (BC) survivors are at an increased risk of long-term cardiovascular disease (CVD), often attributed to cancer treatment. However, cancer treatment may also negatively impact health-related quality of life (HRQoL), a risk factor of CVD in the general population.

OBJECTIVE

We examined whether sleep disturbance, and physical or mental HRQoL were associated with CVD risk in BC survivors.

METHODS

We conducted a longitudinal analysis in the Women's Health Initiative of postmenopausal women given a diagnosis of invasive BC during follow-up through 2010 with no history of CVD before BC. The primary outcome was incident CVD, defined as physician-adjudicated coronary heart disease or stroke, after BC. Physical and mental HRQoL, measured by the Short-Form 36 Physical and Mental Component Summary scores, and sleep disturbance, measured by the Women's Health Initiative Insomnia Rating Scale, were recorded post BC. Time-dependent Cox proportional hazards models were used starting at BC diagnosis until 2010 or censoring and adjusted for relevant confounders.

RESULTS

In 2884 BC survivors, 157 developed CVD during a median follow-up of 9.5 years. After adjustment, higher Physical Component Summary scores were significantly associated with a lower risk of CVD (hazard ratio, 0.90 [95% confidence interval, 0.81-0.99]; per 5-point increment in Physical Component Summary). No associations with CVD were found for Mental Component Summary or Insomnia Rating Scale.

CONCLUSION

In BC survivors, poor physical HRQoL is a significant predictor of CVD.

IMPLICATIONS FOR PRACTICE

Our findings highlight the importance for nurses to assess and promote physical HRQoL as part of a holistic approach to mitigating the risk of CVD in BC survivors.

Somatic acupressure for the fatigue-sleep disturbance-depression symptom cluster in breast cancer survivors: A phase II randomized controlled trial

OBJECTIVE

To evaluate the feasibility of the somatic acupressure (SA) for managing the fatigue-sleep disturbance-depression symptom cluster (FSDSC) among breast cancer (BC) survivors and its preliminary effects.

METHODS

In this Phase II randomized controlled trial (RCT), 51 participants were randomised evenly into the true SA group, sham SA group, and usual care group. All the participants received usual care. The two SA groups performed additional true or sham self-acupressure daily for seven weeks. The primary outcomes related to the assessment of participants' recruitment and compliance with study questionnaires and interventions. Clinical outcomes assessed the preliminary effects of SA on fatigue, sleep disturbance, depression, and quality of life. Semi-structured interviews were undertaken to capture participants' experiences of participating in this study. The statistical effects of the intervention on the outcomes were modelled in repeated measures ANOVA and adjusted generalized estimating equations.

RESULTS

Forty-five participants completed the SA intervention. No adverse events were reported. Over 85% of the participants could sustain for 25 days or more and 15 min or more per session, but the adherence to the intervention requirement was yet to improve. The group by time effect of the FSDSC and depression were significant (p < 0.05). Qualitative findings showed that participants positively viewed SA as a beneficial strategy for symptom management.

CONCLUSIONS

The SA intervention protocol and the trial procedures were feasible. The results demonstrated signs of improvements in targeted outcomes, and a full-scale RCT is warranted to validate the effects of SA on the FSDSC.

Symptom clusters among breast cancer patients in relation to chemotherapy cycles: a longitudinal study

PURPOSE

The aim of this study was to identify symptom clusters in breast cancer patients undergoing adjuvant chemotherapy.

METHODS

A prospective longitudinal study was conducted. And a sample of 620 breast cancer patients receiving adjuvant chemotherapy was recruited using convenience sampling from May 20, 2020, to March 31, 2021. Data were collected eight times: the first chemotherapy cycle (T1) to the eighth cycle of chemotherapy (T8). Exploratory factor analysis was used to explore the composition of symptom clusters.

RESULTS

Symptoms with an incidence of less than 20% were deleted and the remaining symptoms were included in the factor analysis. Three common factors were extracted in T1, including gastrointestinal symptom cluster, emotional and psychological symptom cluster, and menopausal symptom cluster. Five common factors were extracted from T2 to T7, including gastrointestinal symptom cluster, emotional and psychological symptom cluster, neurological symptom cluster, menopausal symptom cluster, and self-image disorder symptom cluster. Four common factors were extracted at T8, including gastrointestinal symptom cluster, emotional and psychological symptom cluster, neurological symptom cluster, and menopausal symptom cluster.

CONCLUSION

Breast cancer patients undergoing adjuvant chemotherapy experience multiple symptoms and different symptom clusters in different chemotherapy cycles. It is a benefit for health care providers to better understand and care for breast cancer patients. It will also help such women to manage concurrent symptoms ahead to promote their quality of life.

Research on the applicability of an exercise rehabilitation app aiming to improve the mental and physical health of breast cancer patients in the post-operative period

Purpose

Breast cancer is one of the most common malignant cancers in women, seriously endangering the physical and mental health of patients. In this study, we developed an app for breast cancer patients undergoing radiotherapy or chemotherapy with a focus on exercise interventions, supplemented by nutritional and psychological interventions, to verify the applicability of the app for these patients and its impact on their quality of life, sleep, and psychological state. We also investigated the patients' experience and perceptions of the app.

Methods

A total of 17 participants, aged 42-58 years, were recruited for this study using a mixed-methods design, including quantitative group pre-and post-test scores and qualitative interview results. The participants used the app for 8-18 weeks depending on their radiotherapy or chemotherapy cycle. During the radiotherapy or chemotherapy period, the participants used the "Yun Dong Ru Kang" exercise rehabilitation app to perform aerobic exercises twice a week, as well as rehabilitation exercises appropriate to their radiotherapy or chemotherapy stage, and used the app on their own the rest of the time. The primary results included their scores on the PSSUQ overall assessment usability questionnaire, the users' use of the app, and the results of the interviews; the secondary indicators were quality of life, sleep status, and anxiety and depression status.

Results

An overall score of 6.2 (out of 7 points) on the PSSUQ questionnaire indicates the high usability; the average use time per subject per week was 97.69 ± 11.82 min, which exceeds the minimum use time, but the average use time tended to decrease as the use time was postponed. Promoted articles on nutritional diets received the most hits. The results of the interviews were consistent with the questionnaire scores, with the majority of participants believing that the means of exercise should be enriched and the interface optimized, while the reduction in the length of use was related to the participants' own state of learning about calisthenics. In the results of the Breast Cancer-Specific Scale FACT-B, there was a significant increase (p < 0.05) in the Emotional Status dimension score and a significant decrease (p < 0.05) on the Additional Concerns dimension score. In the results of the Pittsburgh Sleep Quality Inventory PSQI, there was a non-significant improvement in all items except for a significant increase (p < 0.05) for the Hypnotic Medication item. In the Hospital Anxiety and Depression Scale (HADS), there was no significant improvement in any of the anxiety and depression factors.

Conclusions

The "Yun Dong Ru Kang "app has certain applicability, and the use of the exercise rehabilitation app may effectively reduce the negative impact of chemotherapy side effects on the quality of life, sleep and depression of breast cancer patients in the chemotherapy or radiotherapy phase. Before it is put into use in the future, the app should be enriched with exercise tools, the interface should be optimized, and articles on nutrition and diet should be promoted.

Fatigue in Hematopoietic Cell Transplantation Survivors: Correlates, Care Team Communication, and Patient-Identified Mitigation Strategies

With improved survival after hematopoietic cell transplantation (HCT), the number of individuals at risk for persistent or late effects is increasing. The importance of optimizing HCT survivor health and well-being is mounting. Fatigue is a common post-transplantation symptom that impairs quality of life, yet it remains poorly understood and inadequately addressed. Multiple challenges to addressing fatigue exist, including its multidimensional presentation, multiple (often concomitant) causes, patient-clinician communication barriers, and few highly effective, evidence-based interventions that can be readily implemented. To address these challenges, we sought to better describe the impact and potential causes of fatigue in the post-transplantation setting, fatigue-related communication with clinicians, and the most effective patient-identified mitigation strategies (PIMS) for fatigue. A total of 1703 adult HCT recipients from a single center completed a survey including the Medical Outcomes Survey Short Form-36 (SF-36), PROMIS Fatigue, and other fatigue-related items between July 2017-June 2018. The survey was offered to recipients at their post-transplantation anniversary occurring during this interval. Two independent raters categorized free-text responses about fatigue PIMS. PROMIS Fatigue scores were dichotomized into low (≤55) or high (>55). Associations between high fatigue and participant characteristics and health outcomes were evaluated using the Fisher exact test for categorical variables and the Student 2-sample t test for continuous variables. Among the 1660 respondents with evaluable fatigue scores, 67% underwent allogeneic HCT. The majority of these (n = 1588; 96%) had a malignancy, with hematologic malignancy the most common diagnostic category (n = 1555; 94%). The median time post-transplantation was 11 years (interquartile range, 4 to 20 years). PROMIS item responses indicate that 44% of patients were at least somewhat fatigued and 37% were at least somewhat bothered by it. The mean fatigue score was 50.2 ± 11; 591 patients (36%) had high fatigue, which was associated with worse SF-36 scores across all domains (General Health, Physical Functioning, Emotional Well-being/Mental Health, Social Functioning, Role Limitation due to Physical Health, Role Limitation due to Emotional Health, Vitality [eg, energy], and Bodily Pain). High fatigue also was associated with self-reported chronic graft-versus-host disease, anxiety, depression and sleep problems. Diagnosis of plasma cell disorder and receipt of an autologous transplant were associated with high fatigue (P = .001). Among the 553 individuals who received an autologous transplant, 226 (41%) had multiple myeloma. Compared with the autologous transplant recipients without myeloma group, those with multiple myeloma were significantly more likely to have high fatigue (109 of 226 [48%] versus 118 of 325 [36%]; P < .01). Twenty percent of the patients with high fatigue did not discuss it with their care team. Among the 89 different reasons provided for not discussing it, the most common was "thought they already knew the answer" (n = 21). The 370 survivors with high fatigue who identified at least 1 most effective PIMS generated a total of 639 PIMS. Although the PIMS for fatigue spanned a wide array of strategies, most PIMS were related to sleep/rest (n = 192; 30%) or exercise (n = 139; 22%). Although fatigue is associated with worse HCT survivor-reported outcomes, it is only sometimes discussed with care teams. Survivors identify specific strategies that are most effective. Given its prevalence and impact, clinicians should promote communication about fatigue, treat underlying causes, and recommend sleep/rest and exercise, recognizing that individualized approaches also may be beneficial.

Effectiveness of Pharmacological and Nonpharmacological Interventions for Managing the Fatigue-Sleep Disturbance-Depression Symptom Cluster in Breast Cancer Patients Undergoing Chemotherapy: A Systematic Review

BACKGROUND

The symptom cluster of cancer-related fatigue-sleep disturbance-depression (F-S-D) is common among breast cancer (BC) patients undergoing chemotherapy. Given the coexisting nature and synergistic effect of this symptom cluster, interventions for managing it are expected to benefit patient outcomes.

OBJECTIVES

The aims of this study were to examine the effectiveness and identify the essential components of interventions used to manage the F-S-D and quality of life (QOL) in BC patients undergoing chemotherapy.

METHODS

A systematic review was performed in March 2020 through 7 electronic databases. Relevant studies were assessed using the inclusion criteria. The level of evidence was assessed using the Cochrane risk-of-bias tool. The results were summarized and synthesized in narrative forms.

RESULTS

Sixteen randomized controlled trials were included. Results showed that bright light therapy, acupressure, and psychological nursing interventions were useful in managing F-S-D in BC patients. Exercise and diet counseling alleviated F-D, whereas stress management and a health promotion program alleviated S-D. Bright light therapy, exercise, diet counseling, and psychological nursing interventions enhanced the QOL of these patients.

CONCLUSION

Interventions that could alleviate F-S, F-D, S-D, and F-S-D in BC patients and enhance their QOL were identified. Future studies should investigate the effects of evidence-based multimodal interventions that integrate psychological support, education on the management of chemotherapy side effects, and diet counseling and exercise on F-S-D in and reduced QOL of BC patients undergoing chemotherapy.

IMPLICATIONS FOR PRACTICE

Nurses act as patient advocates, and the development of evidence-based interventions for managing F-S-D and QOL is significant to nursing practice.

Living as a Survivor: Sleep Disturbance, Fatigue, Depressive Mood, and Cognitive Dysfunction After Breast Cancer Treatment

BACKGROUND

Many cancer survivors endure multiple symptoms while striving to return to a normal life. Those symptoms often co-occur and exacerbate one another; however, their interplay is not fully understood.

OBJECTIVE

This study aimed to examine the occurrence and concurrence of sleep disturbance, fatigue, depressive mood, and cognitive dysfunction in posttreatment breast cancer survivors.

METHODS

The data for this descriptive analysis were collected as part of the screening for a clinical trial. The occurrences of sleep disturbance, depressive mood, and cognitive dysfunction were each determined by the cutoff scores of the Pittsburgh Sleep Quality Index, Center for Epidemiological Studies Depression Scale, and Montreal Cognitive Assessment, respectively; fatigue was determined by meeting the International Classification of Diseases cancer-related fatigue criteria.

RESULTS

A convenience sample of 81 women completed chemotherapy or/and radiation for stage I-III breast cancer an average of 23.1 (±SD = 9.0) months ago. Sleep disturbance (85%) was most prevalent, followed by fatigue (67%), depressive mood (46%), and cognitive dysfunction (29%). Of the survivors, 80% reported 2 or more co-occurring symptoms. Worsened subjective sleep quality, sleep disturbance, and daytime dysfunction significantly increased the risk of fatigue by 5.3, 4.3, and 4.3 times (all P < .001) and depression by 2.0, 2.7, and 3.0 times (all P < .05), respectively.

CONCLUSION

Sleep disturbance significantly increased the risk of survivors' fatigue and/or depressive mood after cancer treatment completion.

IMPLICATION FOR PRACTICE

Effectively managing sleep disturbance and improving the individual's sleep perception may subsequently reduce fatigue and/or depressive mood among breast cancer survivors. Nonpharmacological strategies for managing multiple posttreatment symptoms are needed.

A prospective observational study for a Federated Artificial Intelligence solution for moniToring mental Health status after cancer treatment (FAITH): study protocol

BACKGROUND

Depression is a common condition among cancer patients, across several points in the disease trajectory. Although presenting higher prevalence rates than the general population, it is often not reported or remains unnoticed. Moreover, somatic symptoms of depression are common in the oncological context and should not be dismissed as a general symptom of cancer. It becomes even more challenging to track psychological distress in the period after the treatment, where connection with the healthcare system typically becomes sporadic. The main goal of the FAITH project is to remotely identify and predict depressive symptoms in cancer survivors, based on a federated machine learning (ML) approach, towards optimization of privacy.

METHODS

FAITH will remotely analyse depression markers, predicting their negative trends. These markers will be treated in distinct categories, namely nutrition, sleep, activity and voice, assessed in part through wearable technologies. The study will include 300 patients who have had a previous diagnosis of breast or lung cancer and will be recruited 1 to 5 years after the end of primary cancer. The study will be organized as a 12-month longitudinal prospective observational cohort study, with monthly assessments to evaluate depression symptoms and quality of life among cancer survivors. The primary endpoint is the severity of depressive symptoms as measured by the Hamilton Depression Rating Scale (Ham-D) at months 3, 6, 9 and 12. Secondary outcomes include self-reported anxiety and depression symptoms (HADS scale), and perceived quality of life (EORTC questionnaires), at baseline and monthly. Based on the predictive models gathered during the study, FAITH will also aim at further developing a conceptual federated learning framework, enabling to build machine learning models for the prediction and monitoring of depression without direct access to user's personal data.

DISCUSSION

Improvements in the objectivity of psychiatric assessment are necessary. Wearable technologies can provide potential indicators of depression and anxiety and be used for biofeedback. If the FAITH application is effective, it will provide healthcare systems with a novel and innovative method to screen depressive symptoms in oncological settings.

How the COVID-19 pandemic has affected eating habits and physical activity in breast cancer survivors: the DianaWeb study

Purpose

Breast cancer (BC) survivors are increasingly interested in learning about healthy lifestyles to reduce the risk of BC recurrence and mortality. The DianaWeb study, a community-based participatory research, offers BC patients a specific interactive website to help them in adopting and maintain correct lifestyles, in line with World Cancer Research Fund recommendations. However, to limit the spread of the COVID-19 pandemic, most countries introduced restrictions which, inevitably, caused sudden lifestyle changes.

The current study aimed at evaluating changes in lifestyle in BC survivors before, during, and after the first two waves of the COVID-19 pandemic.

Methods

We used data of 224 BC cancer survivors enrolled in the DianaWeb study. We evaluated the adherence to physical activity (PA) guidelines, to Mediterranean diet (MD), and WCRF recommendations, at baseline, during and after the first two waves of the COVID-19 pandemic. We estimated the association between PA, MD, and WCRF adherence with sociodemographic characteristics, years from enrolment in the DianaWeb study, and type of breast cancer.

Results

As expected, during confinement periods, we observed a significant decrease in walking activity and in the percentage of patients performing vigorous PA. In post-quarantine, total weekly energy expenditure increased significantly. BC patients participating in the DianaWeb study for more than 3 years were more likely to be more active. There were no changes in MD and WCRF adherence.

Conclusions

Our results show that the proposed interactive website was useful in achieving durable lifestyle changes, that have not been undermined either during the COVID-19 pandemic.

Implications for Cancer Survivors

Patient education is essential for guiding BC survivors toward improving their health outcomes; therefore, an interactive website like the one proposed by the DianaWeb study may be useful to improve healthy lifestyles.

Cumulative burden of symptomatology in patients with gynecologic malignancies undergoing chemotherapy

OBJECTIVE

Patients with gynecologic malignancies commonly experience distressing symptoms during chemotherapy. This study sought to evaluate whether symptoms accumulated over the course of several chemotherapy cycles, which could provide essential information for planning supportive interventions.

METHOD

Patients with gynecologic malignancies completed questionnaires about fatigue, depressive symptoms, sleep, and physical activity 1 week before and after chemotherapy cycles 1, 3, and 6. Multilevel models examined the effects of time (pre- and postchemotherapy), treatment cycle (1, 3, 6), and their interaction on symptoms. Logistic regression models examined the effects of time, treatment cycle, and their interaction on the proportion of participants exceeding thresholds for clinically meaningful symptomatology.

RESULTS

Most participants (N = 140; Mage = 60.8 years, SD = 10.4) had ovarian cancer (49%) and Stage III disease (55%). Participants reported worse fatigue, depressive symptoms, sleep disturbance, and sleep efficiency from pre- to posttreatment at each cycle (ps < .001). With each successive cycle, participants reported worse pretreatment fatigue (p < .001) and depressive symptoms (p < .01) but better sleep efficiency (p = .02). Fatigue increases attenuated across cycles (p = .04). There were no changes in physical activity. Across time points, at least half of participants met clinical thresholds for fatigue, sleep disturbance, and low sleep efficiency and were minimally physically active. Postchemotherapy cycle 6, 23% of participants reported clinically meaningful depressive symptoms.

CONCLUSIONS

Patients with gynecologic malignancies have high rates of clinically meaningful symptomatology during chemotherapy. Patients may experience a cumulative burden of symptomatology as treatment progresses, which could have therapeutic implications. Early implementation of supportive interventions should be considered to prevent or mitigate cumulative treatment burden. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

The Effect of Temperament on the Association Between Pre-treatment Anxiety and Chemotherapy-Related Symptoms in Patients With Breast Cancer

OBJECTIVE

Pre-treatment anxiety (PA) before chemotherapy increases complaints of chemotherapy-related symptoms (CRS). The results on the association have been inconsistent, and the effect of temperament remains unclear. We aimed to determine whether PA is a risk factor for CRS and the effect of differing temperaments on CRS.

METHODS

This prospective study comprised 176 breast cancer patients awaiting adjuvant chemotherapy post-surgery. We assessed CRS, PA, and temperament using the MD Anderson Symptom Inventory (MDASI), the Hospital Anxiety and Depression Scale, and the short form of the Temperament and Character Inventory-Revised, respectively. The MDASI was re-administered three weeks after the first chemo-cycle.

RESULTS

PA showed weak positive correlation with several CRS after the first cycle; no CRS was significantly associated with PA when pre-treatment depressive symptoms and baseline CRS were adjusted in multiple regression analysis. Moderation model analysis indicated that the PA effect on several CRS, including pain, insomnia, anorexia, dry mouth, and vomiting, was moderated by harm avoidance (HA) but not by other temperament dimensions. In particular, PA was positively associated with CRS in patients with low HA.

CONCLUSION

The results in patients with low HA indicate that more attention to PA in patients with confident and optimistic temperaments is necessary.

An Evidence-Based Somatic Acupressure Intervention Protocol for Managing the Breast Cancer Fatigue-Sleep Disturbance-Depression Symptom Cluster: Development and Validation following the Medical Research Council Framework

BACKGROUND

Somatic acupoint stimulation (SAS) has been frequently utilised as a promising intervention for individual cancer-related symptom management, such as fatigue, sleep disturbance and depression. However, research evidence regarding the role of SAS in mitigating the fatigue-sleep disturbance-depression symptom cluster (FSDSC) has been scant. This study was conducted to develop an evidence-based SAS intervention protocol that can be further implemented in a Phase II randomized controlled trial (RCT) to manage the FSDSC in breast cancer survivors.

METHODS

The Medical Research Council Framework for Developing and Evaluating Complex Intervention (MRC framework) was employed to guide the development procedures of the SAS intervention protocol, including the identification of an existing evidence base, the identification of theories and practice standards, and the validation of the SAS intervention protocol. A content validity study was performed through an expert panel to assess the scientific and practical appropriateness of the SAS intervention protocol. The content validity index (CVI), including item-level CVI and protocol-level CVI, were calculated to evaluate the consensus level of the expert panel.

RESULTS

Key components of the SAS protocol, including the acupoint formula, the SAS modality, technique, intensity and frequency were identified for both a true and placebo SAS intervention based on the best available research evidence retrieved from systematic reviews, clinical trials, and relevant theories, particularly regarding the inflammatory process, yin-yang theory, zang-fu organs and meridians theory, and acupressure practical standards. The true SAS intervention was determined as daily self-administered acupressure on specific acupoints for seven weeks. The placebo SAS was designed as light acupressure on non-acupoints with the same frequency and duration as the true SAS. Excellent content validity was achieved after one round of expert panel assessment, with all the key components of the true and placebo SAS protocols rated as content valid (CVI ranged from 0.86 to 1.00).

CONCLUSIONS

A research-informed, theory-driven and practically feasible SAS intervention protocol for the FSDSC management in breast cancer survivors was developed following the MRC framework. The feasibility and acceptability of the SAS intervention will be further tested in breast cancer survivors through a Phase II RCT.

Clinical and genetic factors associated with self-reported cognitive deficits in women with breast cancer: the "CAGE-Cog" study

Background

Breast cancer patients undergoing chemotherapy treatment are at particular risk of experiencing acute cognitive impairment leading to daily challenges in decision-making and reduced quality of life and functional autonomy. The aim was to assess the relationship between clinical and genetic factors and cognitive function in a sample of patients with breast cancer undergoing chemotherapy.

Methods

A cross-sectional study was carried out between November 2017 and June 2019 on women (N = 112) treated for breast cancer by intravenous chemotherapy at the oncology outpatient unit of Hôtel-Dieu de France Hospital, Beirut. Patients were evaluated with the 37-item Functional Assessment of Cancer Therapy-Cognitive Function (FACT-Cog). Other validated scales were also used to assess depression, anxiety, sleep disorders, pain, and fatigue. DNA was obtained by a buccal swab (FTA®technology) for genotyping of different genes (ABCB1, COMT, DRD2, OPRM1, CLOCK, CRY2, and PER2) using the Lightcycler®(Roche).

Results

The mean age of participants was 56.04 years. Multivariable analysis, taking the four FACT-Cog subscores as the dependent variables, showed that the mean cognitive score decreased with higher depression, anxiety, and insomnia scores. Patients with university education levels had better perceived cognitive abilities than those with primary education. Moreover, carrying the G allele for the OPRM1 polymorphism (c.118A > G;rs197791) was significantly associated with a better cognitive function compared to AA patients (B = 2.05; p = 0.038).

Conclusions

A comprehensive oncological care plan should include a personalized assessment of all factors related to cognitive functioning in cancer patients, particularly anxiety and depression, to achieve an optimal patient outcome.

The Mediating Roles of Anxiety, Depression, Sleepiness, Insomnia, and Sleep Quality in the Association between Problematic Social Media Use and Quality of Life among Patients with Cancer

The present study examined the mediating role of anxiety, depression, sleepiness, insomnia, and sleep quality in the association between problematic social media use and quality of life (QoL) among patients with cancer. This cross-sectional survey study recruited 288 patients with cancer to respond to measures on anxiety, depression, sleepiness, insomnia, sleep quality, problematic social media use, and QoL. Structural Equation Modeling was used for the mediation analysis. There were significant relationships between all of the variables used in the study. It was revealed that problematic social media use did not directly influence the QoL of patients with cancer except via anxiety, depression, sleepiness, and insomnia. Sleep quality did not mediate the association between problematic social media use and QoL. Healthcare workers managing cancer should pay attention to the mental health needs of their patients even as they treat their cancer so as to improve their quality of life. Future studies may examine other variables that affect the QoL of patients with cancer as well as other mediating and moderating variables.

Heterogeneity of symptoms and functions among women receiving chemotherapy for breast cancer in China: A multicentre, cross-sectional study

Background

Currently, few studies have explored the heterogeneity of symptoms and functions in patients with breast cancer. This study aimed to identify the subgroups of symptoms and functions in women receiving chemotherapy for breast cancer and determine whether the subgroups differed in demographic and clinical characteristics.

Methods

A cross-sectional multicenter survey involving five hospitals in Zhejiang, Shanghai, Shandong, and Guangxi provinces of Mainland China was implemented between August 2020 to December 2021. Participants completed questionnaires that included the PROMIS-57, PROMIS cognitive function short form, and demographic and clinical characteristics. Latent class analysis was performed, followed by chi-square test and analysis of variance. Subsequently, significant variables were included in multinomial logistic regression.

Results

A total of 1,180 patients were investigated, with an average age of 48.9 years. Three classes were identified: low symptom burdens and functions group (26.2%, Class 1), moderate symptom burdens and functions group (16.9%, Class 2), and low symptom burdens and high functions group (56.9%, Class 3). Compared with patients in Class 1 and 3, those in Class 2 consistently showed a higher tendency of having urban employee health insurance (odds ratio = 2.506, P &lt; 0.05) and rural health insurance (odds ratio = 2.207, P &lt; 0.05). Additionally, patients in Class 2 tended to be in their fourth cycle of chemotherapy. However, receiving chemotherapy and surgery increased the likelihood of belonging to Class 1.

Conclusions

A high proportion of patients experienced varying degrees of symptom and function issues, suggesting that attention is warranted for women with breast cancer undergoing chemotherapy. Patients with the urban employee basic medical system, the new rural cooperative medical system and in the early stage of chemotherapy cycles were more likely to have symptom burdens. Middle-aged postmenopausal women reported varying degrees of cognitive issues. Additionally, surgery increased the presence of potential long-term effects in functional levels.

Relationship of Muslim Religiosity and Death Anxiety with the Mediating Effect of Optimism and Depression Among Cancer Patients in Pakistan

Optimism and the practice of any religion are known to reduce depression and anxiety in cancer patients. In the present study, the specific role of Muslim religiosity, optimism, depression, and death anxiety in cancer patients has been explored. The sample of this study consisted of 200 cancer patients from different hospitals of the districts Faisalabad and Lahore (Pakistan). The sample's average age was 26.6 years. Parallel mediation findings show that optimism and depression are significant mediators between Muslim religiosity and death anxiety among cancer patients. Muslim religiosity is positively associated with optimism, and it helps to decrease the level of death anxiety, while depression is negatively associated with Muslim religiosity, and high depression increases the death anxiety level of cancer patients. In conclusion, Muslim religiosity and optimism play significant roles in managing depressive symptoms and death anxiety among cancer patients.

Sleep health in young women with breast cancer: a narrative review

PURPOSE

The purpose of this narrative review was to synthesize the evidence on sleep health in young women with breast cancer and provide recommendations for clinical practice and research.

METHODS

Multiple databases were searched (OVID Medline, OVID PsycINFO, OVID Embase, and Scopus) using the search terms "breast neoplasm", "young women", "sleep", "sleep disturbance", "sleep problems", "sleep deficiency", and "insomnia". There were 467 titles and abstracts screened, and 82 full-text papers were reviewed, yielding 11 research publications for inclusion.

RESULTS

Sleep problems are prevalent among young women with breast cancer and are associated with vasomotor symptoms of menopause and psychological symptom distress. The evidence, however, is weak due to methodological and design aspects of the studies.

CONCLUSIONS

Poor sleep health in women with breast cancer is a clinically relevant problem that persists after treatment. As sleep is multidimensional and multifactorial, future research should evaluate sleep with objective sleep measures as well as self-reports; consider longitudinal designs; include factors that potentially contribute to poor sleep quality, such as physical and psychological symptom distress, family stressors, and competing life demands for this age group; and explore the perspective of this younger population of survivors on sleep. For clinical practice, survivorship visits should incorporate sleep assessment for all breast cancer survivors, especially younger women.

Depressive and anxiety symptoms among Japanese cancer survivors: Japan cancer survivorship research project

BACKGROUND

This study aimed to clarify predictors of depressive symptoms and anxiety symptoms after cancer diagnosis among Japanese cancer survivors (CSs).

METHODS

As part of a Japanese cancer survivorship research project commissioned by the Ministry of Health, Labour and Welfare (MHLW) of Japan, we conducted a web-based nationwide survey of CSs in 2018. We analyzed the risk factors for depressive and anxiety symptoms, as measured by the Hospital Anxiety and Depression Scale Japanese version (HADS).

RESULTS

Of 1,234 Japanese CSs, mean score of HADS-depression and HADS-anxiety were 4.08 and 4.78, respectively. At the time of the study, the number of CSs with symptoms of depression and anxiety were 111 (9.0%) and 269 (21.8%), respectively. After multivariable analysis, CSs ≥ 60 years old (reference: ≤ 39 years old, odds ratios (OR): 0.39, 95%CI: 0.17-0.90) and those ≥ 10 years from cancer diagnosis (reference: 0-4 years, OR: 0.55, 95%CI: 0.32-0.96) had lower odds for depressive symptoms. And CSs ≥ 60 years old (reference: ≤ 39 years old, OR: 0.27, 95%CI: 0.15-0.49) and those ≥ 10 years from cancer diagnosis (reference: 0-4 years, OR: 0.62, 95%CI: 0.42-0.90) also had lower odds for anxiety symptoms. CSs who received chemotherapy (OR: 1.56, 95%CI: 1.10-2.20) had higher odds for anxiety symptoms.

CONCLUSIONS

Based on manifestation of symptoms, CSs who were younger, closer to the time of cancer diagnosis, had advanced-staged cancer, or received chemotherapy may be at higher risk for depressive or anxiety symptoms. Those CSs who have higher risk for depression and anxiety symptoms, should be followed-up more carefully for better cancer survivorship, by medical professionals, companies, and society.

Implementing an evidence-based somatic acupressure intervention in breast cancer survivors with the symptom cluster of fatigue, sleep disturbance and depression: study protocol of a phase II randomised controlled trial

INTRODUCTION

The fatigue-sleep disturbance-depression (FSD) symptom cluster, as one of the most common symptom clusters in breast cancer (BC) survivors, can significantly decrease patients' quality of life. Since the management of the FSD symptom cluster has been unsatisfactory with the use of pharmacological treatments alone, non-pharmacological approaches have, therefore, been recommended. Somatic acupressure (SA) is a promising approach given its potential benefits of cancer-related symptom alleviation and the convenience of self-practice. However, research evidence on using acupressure to manage the FSD symptom cluster has been limited. The proposed trial aims to examine the feasibility and preliminary effects of an evidence-based SA intervention for FSD symptom cluster management in BC survivors.

METHODS AND ANALYSIS

This study will be a phase II randomised controlled trial with three study arms and 1:1:1 allocation. Fifty-one early-stage BC survivors who are experiencing the FSD symptom cluster will be randomly assigned to a true SA group, a sham SA group or a usual care group. All participants will receive an education booklet regarding FSD symptom cluster management advice as the usual care package. The participants in the true SA group will additionally receive a 7-week self-administered SA intervention. The participants in the sham SA group will additionally receive self-administered light acupressure at non-acupoints with the same frequency, session and duration as the true SA group. The primary outcomes will be feasibility outcomes related to subject recruitment and completion of study questionnaires and interventions. The secondary outcomes will be the effects of SA on fatigue, sleep disturbance, depression and quality of life. Descriptive statistics will be used to present all the outcomes. The secondary outcomes will be analysed using an intent-to-treat approach.

ETHICS AND DISSEMINATION

Ethical approvals of this trial have been granted by the Human Research Ethics Committee at Charles Darwin University (H19017) and the Clinical Trial Ethics Committee at The Affiliated Hospital of Southwest Medical University (KY2019039). Findings from this trial will be published in peer-reviewed journals and presented at professional conferences.

TRIAL REGISTRATION NUMBER

This trial was registered at ClinicalTrials.gov and the registration number is NCT04118140, with the stage at Recruiting.

The safety and efficacy of using moxibustion and or acupuncture for cancer-related insomnia: a systematic review and meta-analysis of randomised controlled trials

Introduction:

This study aimed to synthesise the best available evidence on the safety and efficacy of using moxibustion and/or acupuncture to manage cancer-related insomnia (CRI).

Methods:

The PRISMA framework guided the review. Nine databases were searched from its inception to July 2020, published in English or Chinese. Randomised clinical trials (RCTs) of moxibustion and or acupuncture for the treatment of CRI were selected for inclusion. Methodological quality was assessed using the method suggested by the Cochrane collaboration. The Cochrane Review Manager was used to conduct a meta-analysis.

Results:

Fourteen RCTs met the eligibility criteria. Twelve RCTs used the Pittsburgh Sleep Quality Index (PSQI) score as continuous data and a meta-analysis showed positive effects of moxibustion and or acupuncture (n = 997, mean difference (MD) = −1.84, 95% confidence interval (CI) = −2.75 to −0.94, p < 0.01). Five RCTs using continuous data and a meta-analysis in these studies also showed significant difference between two groups (n = 358, risk ratio (RR) = 0.45, 95% CI = 0.26–0.80, I² = 39%).

Conclusion:

The meta-analyses demonstrated that moxibustion and or acupuncture showed a positive effect in managing CRI. Such modalities could be considered an add-on option in the current CRI management regimen.

Dual Extrusion Patterning Drives Tissue Development Aesthetics and Shape Retention in 3D Printed Nipple-Areola Constructs

Breast cancer and its most radical treatment, the mastectomy, significantly impose both physical transformations and emotional pain in thousands of women across the globe. Restoring the natural appearance of a nipple-areola complex directly on the reconstructed breast represents an important psychological healing experience for these women and remains an unresolved clinical challenge, as current restorative techniques render a flattened disfigured skin tab within a single year. To provide a long-term solution for nipple reconstruction, this work presents 3D printed hybrid scaffolds composed of complementary biodegradable gelatin methacrylate and synthetic non-degradable poly(ethylene) glycol hydrogels to foster the regeneration of a viable nipple-areola complex. In vitro results showcased the robust structural capacity and long-term shape retention of the nipple projection amidst internal fibroblastic contraction, while in vivo subcutaneous implantation of the 3D printed nipple-areola demonstrated minimal fibrotic encapsulation, neovascularization, and the formation of healthy granulation tissue. Envisioned as subdermal implants, these nipple-areola bioprinted regenerative grafts have the potential to transform the appearance of the newly reconstructed breast, reduce subsequent surgical intervention, and revolutionize breast reconstruction practices.

Physiological and psychosocial correlates of cancer-related fatigue

PURPOSE

Cancer-related fatigue (CRF) is a common and distressing symptom of cancer that may persist for years following treatment completion. However, little is known about the pathophysiology of CRF. Using a comprehensive group of gold-standard physiological and psychosocial assessments, this study aimed to identify correlates of CRF in a heterogenous group of cancer survivors.

METHODS

Using a cross-sectional design to determine the physiological and psychosocial correlates of CRF, ninety-three cancer survivors (51 fatigued, 42 non-fatigued) completed assessments of performance fatigability (i.e. the decline in muscle strength during cycling), cardiopulmonary exercise testing, venous blood samples for whole blood cell count and inflammatory markers and body composition. Participants also completed questionnaires measuring demographic, treatment-related, and psychosocial variables.

RESULTS

Performance fatigability, time-to-task-failure, peak oxygen uptake (V̇O_2peak), tumor necrosis factor-α (TNF-α), body fat percentage, and lean mass index were associated with CRF severity. Performance fatigability, V̇O_2peak, TNF-α, and age explained 35% of the variance in CRF severity. Those with clinically-relevant CRF reported more pain, more depressive symptoms, less perceived social support, and were less physically active than non-fatigued cancer survivors.

CONCLUSIONS

The present study utilised a comprehensive group of gold-standard physiological and psychosocial assessments and the results give potential insight into the mechanisms underpinning the association between physical inactivity, physical deconditioning and CRF.

IMPLICATIONS FOR CANCER SURVIVORS

Given the associations between CRF and both physiological and psychosocial measures, this study identifies targets that can be measured by rehabilitation professionals and used to guide tailored interventions to reduce fatigue.

Symptom Clusters in Head and Neck Cancer: A Systematic Review and Conceptual Model

OBJECTIVE

The two approaches to symptom-cluster research include grouping symptoms and grouping patients. The objective of this systematic review was to examine the conceptual approaches and methodologies used in symptom-cluster research in patients with head and neck cancer.

DATA SOURCES

Articles were retrieved from electronic databases (CINAHL, MEDLINE via Ovid, APA PsycINFO, Scopus, Embase, and Cochrane Central Register of Controlled Trials-CENTRAL), five grey literature portals, and Google Scholar. Seventeen studies met the eligibility criteria. Eight studies grouped symptoms to identify symptom clusters, of which two used qualitative methods. The number of symptom clusters ranged from two to five, and the number of symptoms in a cluster ranged from 2 to 11. Nine studies grouped patients based on their experiences with multiple symptoms. Cluster analysis and factor analysis were most commonly used. Despite variable names and composition of symptom clusters, synthesis revealed three prominent symptom clusters: general, head and neck cancer-specific, and gastrointestinal. Being female and quality of life were significantly associated with high symptom group or cluster severity. Biological mechanisms were sparsely examined.

CONCLUSION

Symptom cluster research in head and neck cancer is emerging. Consensus on nomenclature of a symptom cluster will facilitate deduction of core clinically relevant symptom clusters in head and neck cancer. Further research is required on understanding patients' subjective experiences, identifying predictors and outcomes, and underlying mechanisms for symptom clusters.

IMPLICATIONS FOR NURSING PRACTICE

Identification of clinically relevant symptom clusters would enable targeted symptom assessment and management strategies, thus improving treatment efficiencies and patient outcomes.

Clinical and Genetic Factors Associated With the Breast Cancer-Related Sleep Disorders: The "CAGE-Sleep" Study-A Cross-Sectional Study

CONTEXT

Despite being among the most reported concerns in breast cancer patients, sleep disturbances are still poorly assessed and managed in routine clinical practice. Correctly evaluating these symptoms and understanding the underlying clinical and genetic factors would help medical teams develop an adequate treatment strategy for each patient.

OBJECTIVES

1) To explore the severity of insomnia as well as sleep quality in a sample of Lebanese women with breast cancer undergoing chemotherapy; 2) To examine the correlation between sociodemographic, clinical, psychiatric (anxiety and depression), genetic factors, and alterations in sleep patterns.

METHODS

A cross-sectional study was carried out using the Pittsburgh Sleep Quality Index (PSQI) and Insomnia Severity Index (ISI) (December 2017-June 2019; Ethical reference number: CEHDF1016). All patients gave their written consent and were genotyped for several polymorphisms in CLOCK, CRY2, PER2, COMT, DRD2, OPRM1, and ABCB1 genes using Lightcycler® (Roche).

RESULTS

Our sample included a total of 112 women. Almost half of the patients reported insomnia problems (with 20.5% moderate insomnia and 7.1% severe insomnia). Multivariable analyses taking the PSQI score as the dependent variable, showed that higher depression score and dyslipidemia (yes versus no) were significantly associated with higher PSQI scores (worse sleep quality), whereas having the DRD2 CT genotype versus CC and a higher chemotherapy cycle number were significantly associated with lower PSQI scores (better sleep quality). Depression was also significantly associated with higher ISI scores. When forcing all the genes in each model, the results remained the same except for depression that has been replaced by anxiety in the multivariable analysis.

CONCLUSION

Our study confirms the relationship between anxiety/depression, cycle number, dyslipidemia and DRD2 polymorphism with insomnia and highlights the importance of treating all associated factors to improve the overall QOL of patients.

Feasibility and potential effects of tai chi for the fatigue-sleep disturbance-depression symptom cluster in patients with breast cancer: protocol of a preliminary randomised controlled trial

INTRODUCTION

The fatigue-sleep disturbance-depression symptom cluster (FSDSC) is one of the most common and debilitating side effects in patients with breast cancer (BC) throughout their treatment trajectory. Tai chi has been supported as a promising non-pharmacological intervention for the individual symptom relief of cancer-related fatigue, sleep disturbance and depression. However, relevant evidence of using tai chi for FSDSC management in patients with BC has been lacking.

METHODS

This study will be a two-arm, single-blinded pilot randomised controlled trial involving an 8-week intervention and a 4-week follow-up. Seventy-two patients with BC experiencing the FSDSC will be recruited from two tertiary medical centres in China. The participants will be randomised to either a tai chi group (n=36) or a control group (n=36). The participants in the tai chi group will receive an 8-week tai chi intervention in addition to standard care, while the participants in the control group will receive standard care only consisting of a booklet on the self-management of cancer symptoms. The primary outcomes will include a series of feasibility assessments of the study protocol in relation to the study's methodological procedures, including subject recruitment and follow-up process, completion of study questionnaires and the feasibility, acceptability and safety of the intervention. The secondary outcomes will be the clinical outcomes regarding the effects of tai chi on the FSDSC and quality of life, which will be evaluated by the Brief Fatigue Inventory, the Pittsburgh Sleep Quality Index, the Hospital Anxiety and Depression Scale and the Functional Assessment of Cancer Therapy-Breast questionnaires.

ETHICS AND DISSEMINATION

Ethics approval was obtained from relevant sites (H19094, KY2019133, 201932). The findings of the study will be published in peer-reviewed scientific journals and at conferences.

Psychometric properties of the Korean version of the Pittsburgh Fatigability Scale in breast cancer survivors

BACKGROUND

Fatigability has recently emerged in oncology as a concept that anchors patients' perceptions of fatigue to defined activities of specified duration and intensity. This study aimed to examine the psychometric properties of the Korean version of the Pittsburgh Fatigability Scale (K-PFS) for women with breast cancer.

METHODS

This cross-sectional study involved 196 women with breast cancer recruited from a tertiary hospital in Seoul, Korea. Reliability was evaluated using Cronbach's alpha, and confirmatory factor analysis was conducted to examine the factor structure of the K-PFS. Four goodness-of-fit values were evaluated: (1) the comparative fit index (CFI), (2) the Tucker-Lewis index (TLI), (3) the root mean square error of approximation (RMSEA), and (4) the standardized root mean square residual (SRMR).

RESULTS

Of the 196 survivors, 71.1% had greater physical fatigability (K-PFS Physical score ≥ 15) and 52.6% had greater mental fatigability (K-PFS Mental score ≥ 13). The Cronbach's alpha coefficient for the total K-PFS scale was 0.926, and the coefficients for the physical and mental fatigability domains were 0.870 and 0.864, respectively. In the confirmatory factor analysis for physical fatigability, the SRMR value (0.076) supported goodness of fit, but other model fit statistics did not (CFI = 0.888, TLI = 0.826, and RMSEA = 0.224). For mental fatigability, although three goodness-of-fit values were acceptable (CFI = 0.948, TLI = 0.919, and SRMR = 0.057), the RMSEA value (0.149) did not indicate good model fit. However, each item coefficient was statistically significant (> 0.5), and the K-PFS was therefore found to be valid from a theoretical perspective.

CONCLUSION

This study provides meaningful information on the reliability and validity of the K-PFS instrument, which was developed to meet an important need in the context of breast cancer survivors. Additional research should examine its test-retest reliability and construct validity with performance measures.

Effect of qigong for sleep disturbance-related symptom clusters in cancer: a systematic review and meta-analysis

OBJECTIVES

To examine the effects of qigong interventions on sleep disturbance-related symptom clusters for cancer patients and to explore the possible mediating role of fatigue and depression in affecting sleep.

METHODS

In this systematic review and meta-analysis, a systematic search was conducted through October 2020 by searching multiple English and Chinese databases. Inclusion was limited to randomized controlled trials that measured the effect of qigong on sleep and fatigue/depressive symptoms in cancer patients. Eleven studies involving 907 cancer patients were included in the systematic review, whereas the meta-analysis included ten studies with 851 cancer patients.

RESULTS

The most commonly investigated form of qigong was Taichi, and the intervention length ranged from 10 days to 6 months. All studies employed self-reported measurements. Overall, qigong significantly improved sleep (SMD = -1.28, 95% CI: -2.01, -0.55) and fatigue (SMD = -0.89, 95% CI: -1.59, -0.19) in cancer patients post-intervention, but not depressive symptoms (SMD = -0.69, 95% CI: -1.81, 0.42). Notably, the benefits on sleep and fatigue became non-significant after 3 months. Qigong's effect on sleep was significantly mediated by its effect on fatigue (β = 1.27, SE = 0.24, p = 0.002), but not depressive symptoms (β = 0.53, SE = 0.26, p = 0.106).

CONCLUSIONS

Qigong can be recommended for improving sleep disturbance-fatigue symptom clusters in the cancer population, while qigong's benefit on sleep is likely based on its effect on reducing fatigue. Future qigong studies should adopt more rigorous design and employ strategies to maintain longevity of intervention benefits.

Body image dissatisfaction and lower self-esteem as major predictors of poor sleep quality in gynecological cancer patients after surgery: cross-sectional study

Background

Sleep quality is among the indicators associated with the quality of life of patients with cancer. A multitude of factors may affect patient sleep quality and are considered as associated predictive factors. The aim of this study was to examine the predictors of poor sleep quality in Moroccan women with gynecological cancer after radical surgery.

Methods

A cross-sectional study was carried out at the Oncology Department of the Ibn Rochd University Hospital, Casablanca (Morocco), on women who had undergone radical surgery for gynecological cancer (n = 100; mean age: 50.94 years). To assess sleep quality, symptoms of depression and anxiety, self-esteem and body image, the following translated and validated Arabic versions of the tools were used: Pittsburgh Sleep Quality Index (PSQI), Hospital Anxiety and Depression Scale, Rosenberg’s Self-Esteem Scale and Body Image Scale. To determine predictors of sleep quality, multiple linear and hierarchical regressions were used.

Results

78% of participants were considered poor sleepers, most of them exhibited very poor subjective quality (53%), longer sleep onset latency (55%), short period of sleep (42%) and low rate of usual sleep efficiency (47%). 79% of these patients did not use sleep medication and 28% were in poor shape during the day. Waking up in the middle of the night or early in the morning and getting up to use the bathroom were the main reasons for poor sleep quality. Higher PSQI scores were positively correlated with higher scores of anxiety, depression, body image dissatisfaction and with lower self-esteem (p < 0.001). The medical coverage system, body image dissatisfaction and low self-esteem predicted poor sleep quality. After controlling for the socio-demographic variables (age and medical coverage system), higher body image dissatisfaction and lower self-esteem significantly predicted lower sleep quality.

Conclusion

Body image dissatisfaction and lower self-esteem were positively linked to sleep disturbance in women with gynecological cancer after undergone radical surgery. These two predictors require systematic evaluation and adequate management to prevent sleep disorders and mental distress as well as improving the quality of life of these patients.

The characteristics and related factors of insomnia among postoperative patients with gastric cancer: a cross-sectional survey

Purpose

This study aims to explore the characteristics and related factors of insomnia of patients after operation for gastric cancer.

Methods

A cross-sectional survey was carried out and finally 115 patients with insomnia after operation for gastric cancer were included. The general information, gastric cancer-related information, sleep quality, and other symptoms were investigated.

Results

① The Pittsburgh sleep quality index score of most insomnia patients after gastric cancer surgery was 11-15 points, and the sleep quality rating was “poor”. ② The sleep quality of patients with insomnia after surgery for gastric cancer is related to the number of chemotherapy cycles, fatigue, and depression. ③ The probability of reduced sleep quality with the number of chemotherapy cycles >6 is 3.640 times that of ≤6. The probability of reduced sleep quality during moderate to severe fatigue was 4.390 times that of patients with no or mild fatigue.

Conclusion

Attention to related factors may be associated with improvement of sleep quality in patients with gastric cancer after surgery.

Potential mechanisms of the fatigue-reducing effect of cognitive-behavioral therapy in cancer survivors: Three randomized controlled trials

OBJECTIVE

Fatigue is a common symptom among cancer survivors that can be successfully treated with cognitive-behavioral therapy (CBT). Insights into the working mechanisms of CBT are currently limited. The aim of this study was to investigate whether improvements in targeted cognitive-behavioral variables and reduced depressive symptoms mediate the fatigue-reducing effect of CBT.

METHODS

We pooled data from three randomized controlled trials that tested the efficacy of CBT to reduce severe fatigue. In all three trials, fatigue severity (checklist individual strength) decreased significantly following CBT. Assessments were conducted pre-treatment and 6 months later. Classical mediation analysis testing a pre-specified model was conducted and its results compared to those of causal discovery, an explorative data-driven approach testing all possible causal associations and retaining the most likely model.

RESULTS

Data from 250 cancer survivors (n = 129 CBT, n = 121 waitlist) were analyzed. Classical mediation analysis suggests that increased self-efficacy and decreased fatigue catastrophizing, focusing on symptoms, perceived problems with activity and depressive symptoms mediate the reduction of fatigue brought by CBT. Conversely, causal discovery and post-hoc analyses indicate that fatigue acts as mediator, not outcome, of changes in cognitions, sleep disturbance and depressive symptoms.

CONCLUSIONS

Cognitions, sleep disturbance and depressive symptoms improve during CBT. When assessed pre- and post-treatment, fatigue acts as a mediator, not outcome, of these improvements. It seems likely that the working mechanism of CBT is not a one-way causal effect but a dynamic reciprocal process. Trials integrating intermittent assessments are needed to shed light on these mechanisms and inform optimization of CBT.

Symptom Clusters Predictive of Quality of Life Among Jordanian Women with Breast Cancer

OBJECTIVES

This study was conducted to explore symptom clusters among women with breast cancer in Jordan.

DATA SOURCES

A cross-sectional survey of 516 women with breast cancer who were recruited from three hospitals.

CONCLUSION

This study demonstrated that women with breast cancer experienced several symptoms at the same time. These symptoms tend to cluster in five main groups, and patients experiencing the psychological, nausea and vomiting, and pain clusters are expected to have a lower mean score of quality of life.

IMPLICATIONS FOR NURSING PRACTICE

Nurses need to assess and manage symptoms as clusters to improve the quality of life of women with breast cancer. Symptoms clusters should guide symptoms management practice and be given a priority equal to the active treatment of cancer. Symptoms management and cancer treatment should be started simultaneously.

Who is managing menopausal symptoms, sexual problems, mood and sleep disturbance after breast cancer and is it working? Findings from a large community-based survey of breast cancer survivors

PURPOSE

To determine the nature and severity of vasomotor symptoms, sexual problems, mood and sleep disturbance in community-dwelling breast cancer patients, whether and where they received treatment for these symptoms and their satisfaction with treatment received.

METHODS

Online cross-sectional survey distributed through Breast Cancer Network Australia (BCNA).

RESULTS

524/2286 women responded to the invitation to participate. Of these, 74% (385/523) reported symptoms of interest and were included in the analysis. Mean age was 55.2 years and mean time since breast cancer diagnosis was 5.7 years. Most (66%) had received chemotherapy and were taking endocrine therapy (64%). The most common symptoms were hot flushes/night sweats and sleep disturbance (both 89%), vaginal dryness (75%), mood swings (62%) and sexual problems (60%). Symptoms were mild (21-33%) or moderate (21-38%) in around one third and severe in up to one quarter (8-26%). Symptoms affected the ability to "get on with their life" for 36%, predicted by severity of hot flushes (OR 1.4), sleep disturbance (OR 1.3), mood disturbance (OR 1.3), and sexual problems (OR 1.3). Only 32% were offered treatment, mostly delivered by GPs (33%) or oncologists (26%). Only 49% found this "somewhat effective" and 34% found it ineffective. The majority (60%) wanted more support to manage their symptoms.

CONCLUSION

Menopausal symptoms, sexual problems, mood and sleep difficulties are common after breast cancer and often not effectively managed. There is an unmet need for coordinated care providing effective treatments.

Symptom Profiles of Latina Breast Cancer Survivors: A Latent Class Analysis

BACKGROUND

Symptom research among Latinas with breast cancer is limited-especially as it relates to multiple co-occurring symptoms.

OBJECTIVE

The aim of the study was to identify subgroups (latent classes) of Latinas who have distinct symptom profiles while receiving radiation, chemotherapy, and/or hormonal therapy for breast cancer.

METHODS

This secondary analysis included intake data from three randomized trials of supportive care psychosocial interventions for Latinas treated for breast cancer (n = 290). Prevalence of 12 symptoms-measured using the General Symptom Distress Scale-was entered into the latent class analysis to identify classes of women with different symptom profiles.

RESULTS

Most of the participants had Stage II or III disease, and 81% reported receiving chemotherapy. On average, women reported 4.2 (standard deviation [SD] = 3) symptoms with an overall symptom distress score of 6.4 (SD = 2.5) on a 1-10 scale, with 10 being most distressing. Latent class analysis resulted in three classes that were labeled based on symptoms with the highest prevalence. Class 1 (n = 192) was "Disrupted Sleep and Tired," Class 2 (n = 74) was "Tired," and Class 3 (n = 24) was "Pain, Disrupted Sleep, and Tired." Depression, anxiety, and difficulty concentrating had moderate prevalence in each of the three classes.

DISCUSSION

Beyond the core six symptoms (depression, anxiety, fatigue, pain, disrupted sleep, difficulty concentration), the classes differed in the prevalence of other burdensome symptoms (e.g., nausea, vomiting, constipation), which provide implications for treatment. Thus, it is important to assess for the full range of symptoms so that supportive care interventions can be tailored for the distinct symptom profiles of Latinas with breast cancer.

Self-rated health over a two-year period after breast cancer surgery: prospective ratings and retrospective rating by means of a health-line

BACKGROUND

There are difficulties in clinical assessment of patients' health, and there is a need for evaluating instruments that measures self-rated health over time and that are based on the patient's own experiences of their health situation.

AIM

To describe the trajectory of self-rated health given in a retrospective health-line and its correspondence with the ratings of health given at six different time points during 2 years following a first breast cancer surgery.

DESIGNS AND METHODS

An explorative prospective cohort study presented according to the STROBE guideline. At six time points, 459 women (26-63 years) completed assessments of self-rated health during 2 years following a first breast cancer surgery. Subsequently, the women retrospectively rated health month by month over the two years by means of a health-line. The women were included consecutively in 2007-2009, last data collection was performed in 2012. Statistical analyses were used to compare the health-line with previous ratings.

RESULTS

Most women (74-88%) rated their health as good, very good or excellent at all six time points. Health-line ratings were somewhat lower than the ratings made at the actual time-point; however, the illustrated trajectories back in time followed the same patterns as the women had reported during the two years. The lowest ratings of self-rated health were reported at four months after surgery. The retrospective illustrations varied greatly, and poorer health was reported by women undergoing chemotherapy, with lower education and who reported more life events.

CONCLUSIONS

Even if the retrospective ratings by the health-line were somewhat lower than the ratings at the actual time-point, the health-line captures the health trajectory. The individual graphic illustration by means of a health-line may serve as a basis for assessment and support patient health narratives. The findings indicate that life event, lower education and chemotherapy influence concurrent and retrospective self-assessment of health.
