Distinct Trajectories of Fatigue and Sleep Disturbance in Women Receiving Chemotherapy for Breast Cancer

Effect of training based on Orem's self-care deficit theory on breast cancer patients' management of chemotherapy-related side effects and self-care behaviors: A randomized controlled trial

PURPOSE

To examine the effects of training based on Orem's self-care deficit theory on breast cancer patient's physical, social, and psychological well-being and self-care behaviors during chemotherapy.

METHODS

This randomized controlled trial was based on a pretest-posttest experimental design. The study sample consisted of 62 breast cancer patients (n = 31 for each of the intervention and control groups) receiving cyclophosphamide-epirubicin or cyclophosphamide-adriamycin treatment in the medical oncology department of a university hospital in Tekirdağ, Turkey. The breast cancer patients in the intervention group received training based on Orem's self-care deficit theory regarding physical, social, and psychological well-being and self-care behaviors during chemotherapy. The researcher conducted two face-to-face follow-ups (during the second and third chemotherapy cycles, 3 weeks apart) and a posttest assessment. Pretest and posttest symptom scores and self-care survey results were compared for both groups.

RESULTS

The Nightingale Symptom Assessment Scale (N-SAS) first follow-up, second follow-up, and posttest scores showed that the intervention group experienced fewer negative changes in quality of life than the control group based on the physical, social, and psychological subdimension and total scale scores (p < .05). The most positive changes in the intervention group's self-care behaviors were observed for items about caring for and protecting hair, using protective gloves when doing chores, monitoring weight, and limiting social meetings when blood values were low to protect against possible infection.

CONCLUSION

Training based on Orem's self-care deficit theory positively influenced breast cancer patients' management of chemotherapy-related side effects and self-care behaviors. Chemotherapy-related side effects should be evaluated frequently. Moreover, patients' needs should be determined, and training should be tailored to their needs.

Factors associated with perceived cognitive function in breast cancer patients treated with chemotherapy: A multicenter cross-sectional study

PURPOSE

This study aimed to investigate the factors associated with perceived cognitive function among breast cancer patients treated with chemotherapy in China.

METHODS

The study was a multicenter cross-sectional design. Data were collected from 10 public hospitals in China between April 2022 and February 2023. A total of 741 participants completed questionnaires assessing sociodemographic and medical characteristics, perceived cognitive function, sleep quality, fatigue, anxiety, and depression. Hierarchical multiple regression analysis was used to assess the determinants of cognitive function.

RESULTS

The hierarchical multiple regression model accounted for 31.5% of variation in perceived cognitive function (sociodemographic 4.5%; medical 6.6%; exercise frequency 6.6%; sleep quality 2.1%; fatigue 2.8%; anxiety combined with depression 9.0%). Education level, chemotherapy type, number of chemotherapy cycles, and cyclophosphamide drug use were significant predisposing factors of perceived cognitive function (p < 0.001). Exercising ≥3 times/week (p < 0.001) was a significant factor positively influencing perceived cognitive function, meanwhile, anxiety (p < 0.001) and depression (p < 0 0.001) were negative factors.

CONCLUSION

Our findings suggest that patients with low education levels, postoperative chemotherapy, cyclophosphamide treatment, and a greater number of chemotherapy cycles need more assessment. Sedentary patients, those who have never exercised, and those with anxiety or depression all showed greater cognitive decline. By identifying susceptible populations, encouraging regular exercise, and addressing anxiety and depression, healthcare professionals can contribute significantly to prevent patients' cognitive decline throughout chemotherapy.

Outcomes of physical exercises on initiation, progression, and treatment of breast cancer

The emergence of drug resistance is a substantial obstacle to the effective management of breast cancer, which is the primary cause of cancer-related deaths in women worldwide. To facilitate the development of targeted therapies that can effectively overcome drug resistance, it is crucial to possess a comprehensive comprehension of the molecular mechanisms that underpin resistance to breast cancer treatment. So far, considerable progress has been made in the field of exercise-oncology research and overcome drug resistance, specifically about breast cancer. Evidence has suggested that participation in physical activity is correlated with a decrease in reappearance and fatality rates of breast cancer patients. It has been reported that participation in physical activity can yield favorable outcomes in the prevention, treatment, and post-treatment of breast cancer. An increasing body of empirical evidence suggests that participation in physical activity can alter diverse biological mechanisms, potentially augmenting breast cancer treatments' efficacy. Comparing increased physical activity versus reduced physical activity in breast cancer patients who received chemotherapy, radiotherapy, and surgery supported the significance of exercise in comprehensive care strategies to enhance overall health and treatment efficacy. Furthermore, previous studies have reported that physical activity can enhance the efficacy of breast cancer treatments. This review provides the current literature regarding the influence of physical activity on the occurrence and progression of breast cancer.

Sleep disturbance among breast cancer survivors and controls from midlife to early older adulthood: Pink SWAN

PURPOSE

To compare sleep disturbance from 5 years pre- to 5 years post-diagnosis between breast cancer survivors (BCS) and women without cancer over the same period and to identify BCS subgroups exhibiting different sleep trajectories.

METHODS

Analyses included data from 152 BCS and 2163 controls from 20 years of follow-up in the longitudinal Study of Women's Health Across the Nation (SWAN), a multi-racial/ethnic cohort study. SWAN participants were assessed approximately annually from 1995 to 2015 using a standardized protocol. Pink SWAN focused on women who reported no cancer at SWAN enrollment and developed incident breast cancer after enrollment or did not develop breast cancer. Nonparametric locally weighted scatterplot smoothing plots and linear mixed models were used to compare the prevalence of the most frequently reported sleep problem, frequently waking several times a night (a sleep maintenance problem) during the previous 2 weeks, between BCS and controls in the 5 years pre- to 5 years post-diagnosis. We characterized heterogeneity among BCS on this sleep problem using group-based trajectories and examined pre-diagnosis variables as predictors of group membership.

RESULTS

No differences were found between BCS and controls in prevalence of frequent nighttime awakenings either before or after diagnosis. Among BCS, three trajectory groups were identified. Thirty-seven percent of BCS had consistently low prevalence of waking several times per night, 30% had high prevalence, and 33% had increasing prevalence which started 2 years pre-diagnosis. Prevalence of pre-diagnosis vasomotor symptoms, anxiety, depressive symptoms, and smoking differed among these groups.

CONCLUSION

Among mid-aged women diagnosed with breast cancer, this diagnosis did not trigger/amplify a sleep maintenance problem. The majority of BCS had similar levels of this sleep problem from pre- to post-diagnosis.

IMPLICATIONS FOR CANCER SURVIVORS

Although sleep maintenance problems were not amplified by a cancer diagnosis, a subset of BCS may have sleep issues that should be monitored and treated, as indicated.

Effect of physical exercise on immune, inflammatory, cardiometabolic biomarkers, and fatty acids of breast cancer survivors: results from the MAMA_MOVE Gaia After Treatment trial

PURPOSE

Physical exercise has positive effects on clinical outcomes of breast cancer survivors such as quality of life, fatigue, anxiety, depression, body mass index, and physical fitness. We aimed to study its impact on immune, inflammatory, cardiometabolic, and fatty acids (FA) biomarkers.

METHODS

An exploratory sub-analysis of the MAMA_MOVE Gaia After Treatment trial (NCT04024280, registered July 18, 2019) was performed. Blood sample collections occurred during the control phase and at eight weeks of the intervention phase. Samples were subjected to complete leukocyte counts, cytokine, and cardiometabolic marker evaluation using flow cytometry, enzyme-linked immunoassays, and gas chromatography.

RESULTS

Ninety-three percent of the 15 participants had body mass index ≥ 25 kg/m2. We observed a decrease of the plasmatic saturated FA C20:0 [median difference - 0.08% (p = 0.048); mean difference - 0.1 (95%CI - 0.1, - 0.0)], positively associated with younger ages. A tendency to increase the saturated FA C18:0 and the ratio of unsaturated/saturated FA and a tendency to decrease neutrophils (within the normal range) and interferon-gamma were observed.

CONCLUSIONS

Positive trends of physical exercise on circulating immune cells, inflammatory cytokines, and plasmatic FA were observed. Larger studies will further elucidate the implications of physical exercise on metabolism. These exploratory findings may contribute to future hypothesis-driven research and contribute to meta-analyses.

Inflammatory Breast Cancer: Understanding the Patient Experience

BACKGROUND

Inflammatory breast cancer (IBC) is an aggressive, locally advanced cancer with a 5-year survival rate of approximately 40%. Although patients with IBC likely experience significant and variable symptom burden from diagnosis through survivorship, the description of the symptom burden in this population is limited.

OBJECTIVES

The purpose of this study was to describe the experience of patients with IBC and define the content domain for a patient-reported outcome measure of IBC symptom burden.

METHODS

Twenty patients with IBC described their experience in single qualitative interviews. Content analysis was used to define the symptom burden content domain. Relevance ratings by a panel of experts reduced the number of items for a preliminary patient-reported outcome symptom burden measure.

RESULTS

The mean (SD) participant age was 52.8 (12.0) years; 50.0% had distant metastatic disease, and 85.0% were currently receiving treatment. Content analysis revealed 45 symptoms, with 20 symptoms reported by greater than or equal to 20% of participants. All participants described localized disease-related symptoms. Treatment-related symptoms varied among participants based on the modalities received.

CONCLUSION

Patients with IBC experience symptom burden that is distinct from the symptom burden experienced by patients with non-IBC.

IMPLICATIONS FOR PRACTICE

Differentiating the disease-related symptoms of IBC may assist clinicians in making timely and accurate diagnoses for IBC. A disease- and treatment-specific measure of the symptom burden of IBC should be incorporated in clinical practice to allow for regular assessment and evaluation of symptom burden and implementation of evidence-based interventions for symptom management.

Oncology Outpatients With Worse Anxiety and Sleep Disturbance Profiles Are at Increased Risk for a Higher Symptom Burden and Poorer Quality of Life

BACKGROUND

Anxiety and sleep disturbance are frequent symptoms during chemotherapy.

OBJECTIVES

Purposes were to identify subgroups of oncology outpatients with distinct joint anxiety and sleep disturbance profiles, as well as evaluate for differences in demographic and clinical characteristics, sleep disturbance characteristics, severity of common symptoms, and quality-of-life outcomes among these subgroups.

METHODS

Oncology outpatients (n = 1331) completed self-report measures of anxiety and sleep disturbance 6 times over 2 chemotherapy cycles. Latent profile analysis was done to identify subgroups of patients with distinct joint anxiety and sleep disturbance profiles.

RESULTS

Three profiles were identified (ie, no anxiety and low sleep disturbance (59.7%), moderate anxiety and high sleep disturbance (32.5%), high anxiety and very high sleep disturbance (7.8%)). Compared with the no anxiety and low sleep disturbance class, the other 2 classes were younger; less likely to be married; had a lower annual household income; and had childcare responsibilities. Patients in the 2 worse profiles had problems with both sleep initiation and maintenance. These patients reported higher levels of depressive symptoms, trait and state anxiety, and evening fatigue, as well as lower levels of morning and evening energy, cognitive function, and poorer quality of life.

CONCLUSIONS

More than 40% of patients had moderate or high levels of anxiety and high or very high levels of sleep disturbance. Modifiable risk factors associated with these profiles may be used to develop targeted interventions for 1 or both symptoms.

IMPLICATIONS FOR PRACTICE

Clinicians need to assess for the co-occurrence of anxiety and sleep disturbance.

Trajectories of sleep disturbance in cancer survivors during the first 2 years post-treatment

STUDY OBJECTIVES

To examine the trajectories of sleep disturbance in cancer survivors during the first 2 years post-treatment and to investigate whether psychological, cognitive, and physical factors differentiate trajectories.

METHODS

A total of 623 Chinese cancer survivors of diverse cancer types participated in a 2-year-long prospective study after the completion of cancer treatment. Sleep disturbance was measured using Pittsburgh Sleep Quality Index at 3 (T2), 6 (T3), 12 (T4), 18 (T5), and 24 (T6) months after baseline (within 6-months post-treatment; T1). Latent growth mixture modeling identified distinctive sleep disturbance trajectories and tested if these longitudinal patterns were predicted by baseline psychological distress, attentional control, attentional bias and physical symptom distress and T2 cancer-related distress. Fully adjusted multinomial logistic regression then identified whether these factors differentiated trajectories.

RESULTS

Two distinct sleep disturbance trajectories were identified, namely stable good sleepers (69.7%) and persistent high sleep disturbance (30.3%). Compared to those in the stable good sleep group, patients in the persistent high sleep disturbance group were less likely to report avoidant (OR=0.49, 95% CI = 0.26-0.90), while more likely to report intrusive thoughts (OR = 1.76, 95% CI = 1.06-2.92) and cancer-related hyperarousal (OR = 3.37, 95% CI = 1.78-6.38). Higher depression scores also predicted persistent high sleep disturbance group membership (OR = 1.13, 95% CI = 1.03-1.25). Attentional bias, attentional control, anxiety, and physical symptom distress did not predict sleep trajectory membership.

CONCLUSIONS

One in three cancer survivors experienced persistent high sleep disturbance. Screening and managing depressive symptoms and cancer-related distress in early cancer rehabilitation may reduce risk of persistent sleep disturbance among cancer survivors.

Distinct Profiles of Morning and Evening Fatigue Co-Occurrence in Patients During Chemotherapy

BACKGROUND

Morning and evening fatigue are distinct and distressing symptoms experienced during chemotherapy that demonstrate a large amount of interindividual variability.

OBJECTIVES

The objectives of this study were to identify subgroups of patients with distinct morning and evening fatigue co-occurrence profiles and evaluate for differences among these subgroups in demographic, clinical, and symptom characteristics and quality of life.

METHODS

Oncology patients ( n = 1,334) completed the Lee Fatigue Scale to self-report morning and evening fatigue, six times over two cycles of chemotherapy. Latent profile analysis was used to identify subgroups of patients with distinct morning and evening physical fatigue profiles.

RESULTS

Four distinct morning and evening fatigue profiles were identified (i.e., Both Low, Low Morning + Moderate Evening, Both Moderate, and Both High). Compared to the Both Low profile, the Both High profile was significantly younger, less likely to be married or partnered, more likely to live alone, had a higher comorbidity burden, and lower functional status. The Both High profile had higher levels of anxiety, depressive symptoms, sleep disturbance, and pain and lower levels of quality of life.

DISCUSSION

The variability in the morning and evening severity scores among the four profiles supports the hypothesis that morning and evening fatigue are distinct but related symptoms. Clinically meaningful levels of both morning and evening fatigue were reported by 50.4% of our sample, which suggests that the co-occurrence of these two symptoms is relatively common. Patients in Both Moderate and Both High profiles experienced an extremely high symptom burden that warrants ongoing assessments and aggressive symptom management interventions.

Impact of physical exercise programs in breast cancer survivors on health-related quality of life, physical fitness, and body composition: Evidence from systematic reviews and meta-analyses

Background

Breast cancer is the most common cancer worldwide, and despite remarkable progress in its treatment, the survivors' quality of life is hampered by treatment-related side effects that impair psychosocial and physiological outcomes. Several studies have established the benefits of physical exercise in breast cancer survivors in recent years. Physical exercise reduces the impact of treatment-related adverse events to promote a better quality of life and functional outcomes.

Aim

This study aims to provide an overview of systematic reviews and meta-analyses on the effect of physical exercise on the health-related quality of life, cardiorespiratory fitness, muscle strength, and body composition of breast cancer survivors.

Methods

PubMed and Cochrane databases were searched for systematic reviews and meta-analyses from January 2010 to October 2022. The main focus was ascertaining the effectiveness of physical exercise in breast cancer survivors undergoing curative treatment (surgery and/or radiotherapy and/or chemotherapy). Two reviewers independently screened the literature, extracted the data, and assessed the risk of bias in the included studies.

Results

A total of 101 studies were identified, and 12 were yielded for final analysis. The eligible studies included nine systematic reviews/meta-analyses, one meta-analysis/meta-regression, and two systematic reviews. The number of randomised clinical trials included in each review varied from 11 to 63, and the number of participants was from 214 to 5761. A positive and significant effect of different physical exercise interventions on health-related quality of life was reported in 83.3% (10 studies) of the eligible studies. Physical exercise also improved cardiorespiratory fitness (3 studies; 25%) and showed to be effective in reducing body weight (3 studies; 25%) and waist circumference (4 studies; 33.3%).

Conclusions

Our results suggest that physical exercise is an effective strategy that positively affects breast cancer survivors' quality of life, cardiorespiratory fitness, and body composition. Healthcare professionals should foster the adoption of physical exercise interventions to achieve better health outcomes following breast cancer treatments.

Adjuvant aromatase inhibitor treatment worsens depressive symptoms and sleep quality in postmenopausal women with localized breast cancer: A one-year follow-up study

First-line treatment in postmenopausal women with estrogen- and/or progesterone-positive breast cancer consists of aromatase inhibitors (AROi). The ability of AROi to promote or worsen cognitive function, depressive symptoms, sleep quality and performance in basic activities of daily life as primary and concomitant outcomes in long longitudinal studies in post-menopausal women has been seldom investigated. This study is a cohort trial which aimed to determine if there were differences in cognitive function assessment, depressive symptoms, and sleep quality after 1 year under AROi treatment and to determine the interrelations between these symptoms.

METHODS

A prospective 1-year longitudinal study was performed in a representative sample of tertiary hospital. Women with localized breast cancer newly treated with AROi therapy were evaluated for cognitive functions, depressive symptoms, sleep problems and ability to perform basic activities of the daily life at baseline and after 6 months and 12 months under adjuvant AROi treatment.

RESULTS

Analysis of cognitive functions by the Mini-Mental State Examination (MMSE) scores did not show significantly worsening under AROi treatment after 6 months and 12 months of treatment compared to the baseline. Analysis of depressive symptoms with the Geriatric Depression Scale and sleep quality with the Athens Insomnia Scale (AIS) scores showed significant (p < 0.05) changes after 6 and 12 months of treatment with AROi, with women describing more depressive symptoms and more sleep disturbances.

CONCLUSIONS

Our study found impairments in sleep quality and an increase in depressive symptoms, which has important implications for clinicians as they impair quality of life and adherence to treatment.

Fatigue and Sleep Disturbance among Breast Cancer Patients during Treatment in Saudi Arabia

Background

Fatigue and sleep disturbances are highly prevalent side effects encountered during treatment by patients with breast cancer, and they affect women's quality of life. Most studies investigating sleep and exhaustion in cancer patients provide evidence that supports a strong connection between different sleep parameters and fatigue associated with cancer.

Objective

This study was to assess the level of fatigue and sleep disturbance in breast cancer patients during treatment in Saudi Arabia.

Method

A descriptive cross-sectional study design was conducted on breast cancer patients undergoing treatment in Saudi Arabia. The data were collected through convenience sampling of patients. The study involved self-administered questionnaires comprising three categories: demographic data, perceived Pittsburgh Sleep Quality Index (PSQI), and Functional Assessment of Chronic Illness Therapy–Fatigue (FACIT-F). A total of 101 participants took part in this study. The significant statistical test was determined at a 95% confidence interval and at p < 0.05.

Results

Half of the study participants were aged between 30 and 50 years. Significant differences were found in fatigue and sleep disturbance among BC patients during treatment in Saudi Arabia. A high prevalence of fatigue was found at 21.8%, and 5% of participants experienced sleep disturbance.

Conclusions

Breast cancer patients in Saudi Arabia have a low overall global quality of life. The patients experience poor sleep quality and fatigue, which suggests that during treatment, patients need to be assessed routinely for these symptoms to prevent or reduce fatigue and sleep disturbance. Sleep disturbance might be correlated with fatigue.

A Comparison of the Effects of Self-Acupressure and Aerobic Exercises on Sleep Disorders of Breast Cancer Survivors: A Controlled Randomized Clinical Trial

Background

Breast cancer is the most widespread cancer type, with more than half of the afflicted women suffering from sleep disorders and fatigue, as common complications of the treatment. This study aimed to evaluate the effects of acupressure and aerobic exercises on such women's sleep disorders.

Materials and Methods

This study was carried out on 99 women affected by breast cancer. Participants were divided to acupressure, exercise, and control groups. The acupressure group received the treatment 3 days a week for 8 weeks. The exercise group participated in aerobic exercises 3 times a week for 8 weeks. The control group received routine care in the oncology clinic. Sleep quality was assessed by Pittsburg sleep quality index.

Result

The overall score of sleep quality scale in the acupressure and exercise groups was significantly less than that in the control group at weeks 4 (Medical Doctor: 2.7 with 95% confidence interval [CI]: 1.67 to 1.12) and 8 (MD: 0.07 with 95% CI: -1.21 to 1.03) of intervention. However, there was no significant difference between the acupressure and exercise groups.

Conclusion

The results of this study indicated that both acupressure and exercise methods can be effective and safe methods in reducing sleep disorders of breast cancer survivors and neither is superior to the other.

Symptom trajectories in patients with breast cancer: An integrative review

Objective

This study aimed to synthesize the available knowledge of symptom trajectories in patients with breast cancer and identify predictors associated with these trajectories.

Methods

Whittemore and Knafl’s integrative review method was employed to guide a systematic search for literature in four databases (PubMed, Embase, Web of Science, and CINAHL). The retrieved articles’ publication time was limited to 2010 to 2020, and only peer-reviewed English articles were included.

Results

Twenty-seven articles were included. The findings of the relevant studies were analyzed using thematic analysis. They were grouped into two themes: symptom trajectories of patients with breast cancer (symptom trajectories in patients with breast cancer, in patients who underwent surgery, and in patients who received cancer-related treatment) and associated factors (socioeconomic factors, health characteristics, cancer-related treatment characteristics). Newly diagnosed patients tended to report high trajectories of depression and persistent sleep disturbance. Most patients who underwent surgery reported significant sleep disturbance and anxiety shortly after surgery. For patients who received cancer-related treatment, only a small proportion had a high level of physical activity after cancer-related therapy over time. A high body mass index, a low relationship quality, parental responsibilities, insufficient social support, a low educational background, and an unhealthy lifestyle may increase the risk of negative symptom trajectories in patients with breast cancer. Additionally, old patients were more likely to report cognitive impairment after chemotherapy, while young patients tended to report trajectories of persistent sexual dysfunction. Concurring symptoms and poor health status also contributed to adverse symptom trajectories.

Conclusion

The findings of this review add to the body of knowledge of the interindividual variability of symptom trajectories in patients with breast cancer. Despite the overall similarity in appraisal at baseline, the patients reported varied symptom trajectories over time. It is recommended that nurses consider sociodemographic, clinical and cancer-related treatment characteristics and perform targeted early preventive interventions for patients with breast cancer.

Longitudinal Analysis of Sleep Disturbance in Breast Cancer Survivors

BACKGROUND

Breast cancer survivors (BCS) often report poor sleep quality and wakefulness throughout the night as the greatest challenges experienced during and posttreatment.

OBJECTIVES

This study aimed to elucidate characteristics of sleep disturbances and determine potential predictors that affect sleep disturbances in BCS for 2 years postchemotherapy.

METHODS

This is a secondary analysis of data from the EPIGEN study, which longitudinally examined sociodemographic and cancer-related factors, lifestyle, symptom characteristics, and epigenetic factors at baseline prior to chemotherapy (T1), the midpoint (T2), 6-month (T3), 1-year (T4), and 2-year (T5) time points postchemotherapy. Temporal lifestyle changes, symptom characteristics, and epigenetic factors were explored using linear mixed-effects models with a random intercept. A linear regression model was fitted to identify significant predictors of sleep disturbances at each time point.

RESULTS

In 74 BCS with an average age of 51 years and 70% non-Hispanic White, BCS experienced severe sleep disturbances at T2, which gradually improved over time. Significant temporal changes in midsleep awakenings, early awakenings, and fatigue at work were observed, with disturbances being elevated at T2. Anxiety (T1, T2, and T4), fatigue (T3 and T4), and perceived stress (T3) were significant predictors after adjusting for radiation therapy, surgery, and adjuvant endocrine therapy.

DISCUSSION

This study highlights that predictors of sleep disturbances change over time, with anxiety being a factor earlier in the treatment trajectory (prechemotherapy) and continuing over time with fatigue and perceived stress being involved later in the treatment trajectory. Our results indicate that symptom management strategies to address sleep disturbances should be tailored to the temporal factors that may change in severity during active treatment and early survivorship period. Findings gained from this study on sleep disturbance patterns and the potential risk factors can be incorporated into clinical practice in planning education and developing interventions.

Symptom-related patient-provider communication among women with breast cancer receiving chemotherapy

PURPOSE

The purpose of this study was to determine the extent to which women being treated for breast cancer discussed their symptoms during the week prior to a clinic visit.

METHOD

Women reported the severity of 11 symptoms (0-10 scale) daily using an automated patient-reported outcomes system. Clinic visits were audio recorded, and symptom discussions were coded. Moderate to severe symptoms reported in the week prior to the visit were compared to the symptoms discussed at the visit.

RESULTS

Twenty-six clinic visits of 10 women (mean age, 51.6 years; half had advanced disease) were recorded. In the week prior to their visits, participants provided 183 reports of moderate to severe symptoms. Reported symptoms were discussed at 49.5% of visits, with 36% of discussions initiated by patients. These discussions were more likely to include assessment and normalizing and were less focused on intensifying symptom management. Symptom discussions were more likely with younger women and the time spent discussing symptoms decreased over subsequent visits for all women.

CONCLUSIONS

Women who are symptomatic during treatment are not systematically queried about their symptoms, nor are women effectively reporting their symptoms. Attention should be directed at eliciting symptoms from older women; symptoms should be discussed throughout the duration of chemotherapy.

Insomnia and Fatigue Symptom Trajectories in Breast Cancer: A Longitudinal Cohort Study

Objective: Insomnia and fatigue are common, although not inevitable, during breast cancer. This study is one of the first aiming to describe distinct trajectory classes of insomnia and fatigue symptoms, and their correlates, from diagnosis through treatment.Methods: This longitudinal cohort study was conducted at a comprehensive cancer center and community oncology practices. Participants (N = 460) were women diagnosed with any stage of breast cancer in the previous 4 months. Primary outcomes for this ancillary study of the existing cohort were self-reported insomnia and fatigue symptoms assessed repeatedly across 12 months.Results: Four distinct classes of insomnia symptoms emerged: persistently very high, clinically elevated symptoms (13.7%); high, clinically elevated symptoms (65.9%); stable low (17.2%) or very low (2.6%) symptoms. Five fatigue symptom classes included high, increasing fatigue (9.6%), two recovery classes starting at high (26.3%), or moderate (18.0%) severity at diagnosis, stable low (33.3%) or very low (12.2%) classes. In multivariate analyses, higher depressive symptoms, anxiety, and chronic life stress were associated with being in the very high insomnia class versus the low symptom class. Oncologic factors were not associated with insomnia class membership. Receiving chemotherapy was linked significantly to high and recovery fatigue symptom classes versus the low class. Higher chronic life stress was associated with more persistent fatigue symptoms.Conclusions: Distinct classes of insomnia and fatigue symptoms were evident; 79.6% of the women had clinically elevated, persistent insomnia symptoms, 53.9% had elevated fatigue. A substantial minority evidenced low symptoms, suggesting targeted or stepped-care approaches to symptom management.

Effect of Reiki Therapy on Quality of Life and Fatigue Levels of Breast Cancer Patients Receiving Chemotherapy

BACKGROUND

The quality of life of patients receiving chemotherapy decreases, and fatigue is one of the most common symptoms. Reiki is used for cancer patients as an energy-based complementary and alternative method.

OBJECTIVE

The aim of this study was to determine the effect of Reiki therapy on the quality of life and fatigue levels in breast cancer patients receiving chemotherapy.

METHODS

This was a pretest-posttest, quasi-experimental study with a control group: 70 patients enrolled with 35 participants in the experimental group and 35 in the control group. The experimental group received 6 sessions of Reiki therapy. The data were collected using a Patient Information Form, the Piper Fatigue Scale, and the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire.

RESULTS

The mean scores on the general well-being subscale in the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire increased in the experimental group and decreased in the control group, whereas the mean scores on the general function and general symptom subscales decreased in the experimental group and increased in the control group. The differences between the groups were statistically significant (P < .001). The mean Piper Fatigue Scale scores of the experimental group decreased, whereas that of the control group increased; the group differences were statistically significant (P < .001).

CONCLUSION

Reiki can reduce fatigue and increase the quality of life of breast cancer patients receiving chemotherapy.

IMPLICATIONS FOR PRACTICE

Reiki therapy can be used as a nursing intervention to increase the quality of life and reduce fatigue in breast cancer patients receiving chemotherapy.

Cancer-related fatigue: an overview

A diagnosis of cancer is a major life stressor that can affect the physiological, psychological and physical state of the person concerned. Fatigue is a particularly common and troubling symptom that has a negative impact on quality of life throughout all phases of treatment and stages of the illness. The aim of this review is to provide background information on cancer-related fatigue. This review discusses cancer-related fatigue (CRF) in terms of the definition, prevalence, risk factors, aetiology, and the measurement scales used. The differences between definitions of symptoms and relevant theories will be explored and discussed to help explain the variety of instruments used in its measurement. The prevalence of fatigue will be assessed by looking critically at the evidence of fatigue and the factors that affect it. Potential treatment and management strategies for CRF will also be discussed. Finally, there will be an overview of the instruments used to measure fatigue. This review also provides important evidence for measuring and managing CRF that can help nurses to understand fatigue among patients with cancer. Assessing CRF should be routinely undertaken in clinical settings to help identify the proper interventions, treatments and management to reduce fatigue among cancer patients.

Factors associated with sleep disturbances in women undergoing treatment for early-stage breast cancer

PURPOSE

The purpose of this study was to examine factors associated with sleep disturbance in women receiving adjuvant therapy for breast cancer.

METHODS

This study employed a cross-sectional design using data collected at 3 months post-surgery from an ongoing longitudinal parent study. Participant data were divided into adjuvant treatment groups (chemotherapy, radiation, and aromatase inhibitors) and no adjuvant treatment groups. Symptoms were measured using patient self-report measures. Analysis of variance was used to assess between adjuvant treatment group differences in sleep disturbance. Regression analysis was performed to assess the relationship between sleep disturbance and other symptoms within adjuvant treatment groups.

RESULTS

The sample included 156 women diagnosed with early-stage breast cancer. There were significant differences in levels of reported sleep disturbance between treatment groups (p = 0.049), with significantly higher levels of sleep disturbances in those receiving radiation compared to those receiving no adjuvant treatment (p = 0.038) and in those receiving chemotherapy and those receiving no adjuvant treatment (p = 0.027). Increased sleep disturbance was found to be a significant predictor for increased pain severity, nausea severity, anxiety, depressive symptoms, fatigue, decreased physical function, and decreased ability to participate in social roles and activities. Co-occurring symptoms with sleep disturbance differed between adjuvant treatment groups. Sleep disturbance was also associated with younger age (p = 0.008).

CONCLUSIONS

Patients undergoing chemotherapy or radiation for breast cancer report higher levels of sleep disturbance than those not receiving adjuvant therapy. Sleep disturbance is associated with other symptoms experienced by patients with cancer and thus requires continual assessment and future research into effective interventions.

Do all patients with cancer experience fatigue? A longitudinal study of fatigue trajectories in women with breast cancer

BACKGROUND

Fatigue is a common and expected side effect of cancer treatment. However, the majority of studies to date have focused on average levels of fatigue, which may obscure important individual differences in the severity and course of fatigue over time. The current study was designed to identify distinct trajectories of fatigue from diagnosis into survivorship in a longitudinal study of women with early-stage breast cancer.

METHODS

Women with stage 0 to stage IIIA breast cancer (270 women) were recruited before (neo)adjuvant therapy with radiotherapy, chemotherapy, and/or endocrine therapy and completed assessments at baseline; posttreatment; and at 6 months, 12 months, and 18 months of follow-up. Growth mixture modeling was used to identify trajectories of fatigue, and differences among the trajectory groups with regard to demographic, medical, and psychosocial variables were examined.

RESULTS

Five distinct trajectories of fatigue were identified: Stable Low (66%), with low levels of fatigue across assessments; Stable High (13%), with high fatigue across assessments; Decreasing (4%), with high fatigue at baseline that resolved over time; Increasing (9%), with low fatigue at baseline that increased over time; and Reactive (8%), with increased fatigue after treatment that resolved over time. Both psychological and treatment-related factors were found to be associated with fatigue trajectories, with psychological factors most strongly linked to high fatigue at the beginning of and over the course of treatment.

CONCLUSIONS

There is considerable variability in the experience of fatigue among women with early-stage breast cancer. Although the majority of women report relatively low fatigue, those with a history of depression and elevated psychological distress may be at risk of more severe and persistent fatigue.

Preferences of Individuals With Cancer for Patient-Reported Outcome Measures

PURPOSE

Symptom monitoring and management using patient-reported outcome (PRO) measures improves outcomes for individuals with cancer. The purpose of the current study was to provide a qualitative assessment of preferences of individuals with cancer for PRO measures.

PARTICIPANTS & SETTING

15 patients receiving systemic therapy at the University of Texas MD Anderson Cancer Center.

METHODOLOGIC APPROACH

Participants completed three PRO measures. Qualitative interviews were conducted, and content analysis was used to identify relevant themes.

FINDINGS

Identified themes were the importance of communicating various aspects of the disease and treatment experience to the oncology team, the importance of systematic PRO assessments, congruence among PRO questionnaires and questions clinicians ask at clinic visits, concerns about the length of PRO questionnaires, the importance of the response options available in PRO questionnaires, and willingness to complete PRO measures frequently.

IMPLICATIONS FOR NURSING

Oncology nurses are critical facilitators of the systematic use of PRO measures across the cancer care continuum.

Analysis of Delirium From the Dynamic Symptoms Model: A Literature Review

Delirium is a manifestation of brain injury or acute and generalized dysfunction of the upper cerebral cortical processes. In this way, it is important to analyze delirium more broadly as a symptom to understand and intervene taking into account that it is manifesting the presence of brain lesions whose consequences are deleterious to the neurological performance of patients. This article is intended to present a comprehensive approach of delirium analyzed from a symptom perspective and from theoretical and conceptual structure, such as the Dynamic Symptoms Model, specific to the nursing practice. A literature review related to delirium and components of Dynamic Symptoms Model was carried out. We searched the MEDLINE, ScienceDirect, SciELO, and Scopus databases using the terms Delirium, Intensive Care Units, Nursing, and Risk Factor. The existing literature provides evidence of the antecedents, experience, interventions, interactions, and consequences of delirium, which are components of the Model. Thus, the analysis from the Dynamic Symptoms Model perspective bears relevance and contributes to the understanding and approach of delirium.

Prevalence of Fatigue in Patients With Cancer: A Systematic Review and Meta-Analysis

CONTEXT

Fatigue is a particularly common and troubling symptom that has a negative impact on quality of life throughout all phases of treatment and stages of the illness among patients with cancer.

OBJECTIVES

The objective of this meta-analysis is to examine the present status of fatigue prevalence in patients with cancer.

METHODS

The following databases were searched: PubMed, MEDLINE, EMBASE, PsycINFO, Cochrane Library, from inception up to February 2020. Prevalence rates were pooled with meta-analysis using a random-effects model. Heterogeneity was tested using I-squared (I²) statistics.

RESULTS

A total of 129 studies (N = 71,568) published between 1993 and 2020 met the inclusion criteria. The overall prevalence of fatigue was 49% (34,947 of 71,656 participants, 95% CI = 45-53) with significant heterogeneity between studies (P < 0.000; τ² = 0.0000; I² = 98.88%). Subgroup analyses show that the prevalence of fatigue related to type of cancer ranged from 26.2% in patients with gynecological cancer to 56.3% in studies that included mixed types of cancer. In advanced cancer stage patients, the highest prevalence of fatigue (60.6%) was reported. Fatigue prevalence rates were 62% during treatment and 51% during mixed treatment status. The prevalence of fatigue decreased from 64% in studies published from 1996 to 2000 to 43% in studies published from 2016 to 2020. Metaregression identified female gender as a significant moderator for higher prevalence of fatigue, whereas mean age is not associated with fatigue.

CONCLUSION

This meta-analysis highlights the importance of developing optimal monitoring strategies to reduce fatigue and improve the quality of life of patients with cancer.

Trajectories of Depressed Mood and Anxiety During Chemotherapy for Breast Cancer

BACKGROUND

Women are at risk of mood disturbance during treatment for breast cancer.

OBJECTIVE

The aims of this study were to identify classes of women experiencing similar trajectories of depressed mood and anxiety while receiving chemotherapy for breast cancer and to determine associated antecedents and outcomes. The specific aims were to (1) determine the distinct trajectory classes associated with severity of depressed mood and anxiety reported by women undergoing cycles 2 and 3 of chemotherapy for breast cancer, (2) determine if class membership is associated with various antecedent variables, and (3) determine if class membership is associated with days of missed work and hours spent lying down.

METHODS

In a secondary analysis, classes were identified using Latent Growth Mixture Modeling. Antecedents and outcomes related to class membership were explored.

RESULTS

Participants (n = 166; mean age, 53 [SD, 10.8] years) were mostly white (91.46%); half had early-stage disease. Two trajectories of depressed mood and anxiety were identified. Receipt of doxorubicin was associated with the higher severity class for depressed mood (P < .01) and anxiety (P = .04). No college education (P = .03) or spending more hours lying down (P = .03) was associated with the higher severity class for anxiety.

CONCLUSIONS

Distinct trajectories of mood disturbance are distinguished by baseline severity. Further study is needed to determine if biologic or genomic factors are associated with class membership.

IMPLICATIONS FOR PRACTICE

Identification of women at risk of mood disturbance may allow clinicians to intensify symptom management. Mood disturbance early in the treatment trajectory warrants management to improve outcomes.

Impact of Psycho-Social Factors on Fatigue among Breast Cancer Patients Who Are Currently Undergoing Radiotherapy

Fatigue in breast cancer patients undergoing radiotherapy has been studied less comprehensively than fatigue from chemotherapy. The aim of this study was to test the impact of psycho-social factors on the fatigue among breast cancer patients undergoing radiotherapy. This was a cross-sectional correlational study and participants were 210 breast cancer patients currently undergoing radiotherapy in an outpatient setting in Korea. Data collection was carried out from 22 July to 30 September 2019. The results of this study showed that symptom assessment, anxiety and depression, uncertainty, and perceived stress had a direct effect on the fatigue of breast cancer patients receiving radiotherapy, while social support had an indirect effect. These factors explained 67.2% of the fatigue among the participants. This study confirmed that various interventions for symptom assessment, anxiety and depression, uncertainty, and stress reduction need to be developed to reduce fatigue of breast cancer patients receiving radiotherapy. The present results form the basis for developing such interventions.

Symptom Care at Home: A Comprehensive and Pragmatic PRO System Approach to Improve Cancer Symptom Care

INTRODUCTION

There is growing recognition that systematically obtaining the patient's perspective on their health experience, using patient-reported outcomes (PRO), can be used to improve patient care in real time. Few PRO systems are designed to monitor and provide symptom management support between visits. Patients are instructed to contact providers between visits with their concerns, but they rarely do, leaving patients to cope with symptoms alone at home. We developed and tested an automated system, Symptom Care at Home (SCH), to address this gap in tracking and responding to PRO data in-between clinic visits. The purpose of this paper is to describe SCH as an example of a comprehensive PRO system that addresses unmet need for symptom support outside the clinic.

METHODS FOR PRO SCORE INTERPRETATION

SCH uses pragmatic, single-item measures for assessing symptoms, which are commonly used and readily interpretable for both patients and providers. We established alerting values for PRO symptom data, which was particularly important for conserving oncology providers' time in responding to daily PRO data.

METHODS FOR DEVELOPING RECOMMENDATIONS FOR ACTING ON PRO RESULTS

The SCH system provides automated, just-in-time self-management coaching tailored to the specific symptom pattern and severity levels reported in the daily call. In addition, the SCH system includes a provider decision support system for follow-up symptom assessment and intervention strategies.

DISCUSSION

SCH provides PRO monitoring, tailored automated self-management coaching, and alerts the oncology team of poorly controlled symptoms with a provider dashboard that includes evidence-based decision support for follow-up to improve individual patients' symptom care. We particularly emphasize our process for PRO selection, rationale for determining alerting thresholds, and the design of the provider dashboard and decision support. Currently, we are in the process of updating the SCH system, developing both web-based and app versions in addition to interactive voice response phone access and integrating the SCH system in the electronic health record.

Benefits of a WeChat-based multimodal nursing program on early rehabilitation in postoperative women with breast cancer: A clinical randomized controlled trial

BACKGROUND

Primary treatments for early-stage breast cancer can cause adverse effects, such as pain, fatigue, and sleep disturbance, that can markedly affect the patients' health-related quality of life.

OBJECTIVE

This study aimed to evaluate the benefits of a WeChat-based multimodal nursing program on early rehabilitation in postoperative women with breast cancer.

DESIGN

Clinical randomized controlled trial.

SETTING

Surgical breast cancer department of a general hospital in Shaanxi Province, China.

PARTICIPANTS

Women with breast cancer were recruited via convenience sampling. The inclusion criteria were (1) age ≥18 years, (2) newly diagnosed with breast cancer, (3) stage I-III disease, and (4) indicated for surgery with adjuvant therapy. Exclusion criteria were (1) comorbidity with other malignant tumors and infections and (2) cognitive or psychiatric disorders.

METHODS

We recruited patients with breast cancer and randomly allocated them to the intervention (n = 56) and control (n = 55) groups. The former was subjected to the WeChat-based multimodal nursing program plus routine nursing care for 6 months, whereas the latter received only routine nursing care. The primary endpoint (health-related quality of life) and secondary endpoints (pain, fatigue, and sleep) were measured using the Functional Assessment of Cancer Therapy-Breast version 4.0 (FACT-Bv4.0) and the Numerical Rating Scale at 4 time points (i.e., pre-surgery and 1, 3, and 6 months post-surgery).

RESULTS

The intervention group had significantly improved total FACT-Bv4.0 scores owing to the effects of group (F = 16.28, P < 0.001), time (F = 28.82, P < 0.001), and group-time interaction (F = 5.35, P = 0.001). Similar improvements were also found in social/family well-being and functional well-being (P < 0.05). Emotional well-being was improved based on the effects of time (F = 42.12, P < 0.001) and group-time interaction (F = 10.20, P < 0.001). The 'breast cancer-specific subscale for additional concerns' was affected by group (F = 21.55, P < 0.001) and time (F = 28.96, P < 0.001), whereas physical well-being was only affected by time (F = 35.39, P < 0.001). Pain, fatigue, and sleep were not significantly influenced by group effects.

CONCLUSIONS

We found a significant improvement in the health-related quality of life of postoperative women with breast cancer who used the WeChat-based multimodal nursing program during early rehabilitation. This demonstrated that the program is an effective intervention for postoperative rehabilitation in such patients. Findings of the study will provide evidence for eHealth services in clinical and transitional nursing care.

Meta-Analysis of Changes in Sleep Quality of Women with Breast Cancer before and after Therapy

Cancer treatments may affect the sleep quality and even future quality of life of women with breast cancer. A meta-analysis was performed to understand the changes in the sleep quality of women with breast cancer during their treatment period. In a systematic literature review in compliance with the PRISMA guidelines, we searched for articles published between 2000 and 2018 in databases. A total of 12 study articles were included. The standardized mean differences of the pooling effect size of sleep quality between the period before treatment and 1-8 weeks, 9-16 weeks, 17-24 weeks, and 25-56 weeks after the commencement of treatment were -0.020, -0.162, 0.075, and 0.216, respectively. Although the differences were not statistically significant, in view of the heterogeneity among the studies, we conducted further analysis using a linear mixed effect model. The overall results indicated poorer sleep quality as time passed from the start of the first treatment (p = 0.014). The results of this study revealed that patients experienced better sleep quality in the initial months after the beginning of treatment; however, their sleep quality became poorer between 4 months to approximately 1 year after the beginning of treatment, compared with the sleep quality before treatment, and continued to decline rather than improve during the follow-up period.

Symptom Trajectories Are Associated With Co-occurring Symptoms During Chemotherapy for Breast Cancer

CONTEXT

Symptoms are reported to co-occur during treatment for breast cancer. We previously identified three patterns of fatigue and two patterns of disturbed sleep, depressed mood, and anxiety in women undergoing chemotherapy for breast cancer using a Latent Growth Mixture Model.

OBJECTIVES

The purpose of this study was to explore whether membership in symptom classes of fatigue, disturbed sleep, depressed mood, and anxiety is associated with other symptoms at moderate-to-severe levels.

METHODS

Using data from three longitudinal studies, Wilcoxon rank-sum tests and Jonckheere-Terpstra tests for trend were used to distinguish between classes of women on co-occurring symptoms. Summative scores were calculated, including the number of days subjects reported moderate-to-severe levels (4 or higher on a 0-10 scale) of seven symptoms during two cycles of chemotherapy and compared to class membership.

RESULTS

Participants (n = 166) in the higher fatigue severity class reported more days with moderate-to-severe disturbed sleep, depressed mood, anxiety, nausea, and trouble thinking. Women in the higher severity disturbed sleep class reported more days with moderate-to-severe fatigue, depressed mood, anxiety, and trouble thinking. Women in the higher depressed mood severity class reported more days with moderate-to-severe fatigue, disturbed sleep, anxiety, and nausea. Women in the higher anxiety severity class reported more days with moderate-to-severe fatigue, disturbed sleep, and depressed mood.

CONCLUSION

Moderate-to-severe symptoms co-occur during cancer treatment for breast cancer. The dynamic process of multiple symptoms may be altered by future identification of a shared etiology.

Factores personales que afectan la calidad de vida de mujeres con cáncer de mama del noreste de México: Personal factors that affect quality of life of women with breast cancer from the northeast of Mexico

Introducción: La terapia sistémica para el cáncer de mama afecta la calidad de vida de las mujeres y sus familias. Se analizó la influencia de los factores personales sobre la percepción de calidad de vida de mujeres en tratamiento para el cáncer mamario. Métodos: Participaron noventa y cinco asistentes a la consulta de un hospital público del noreste de México. Se aplicaron dos Cuestionarios de la Organización Europea para la Investigación y Tratamiento del Cáncer (EORTC QLQ-C30 y EORTC QLQ-BR23). Resultados: La edad promedio fue de 55 años ( DE = 9.24). Las participantes destacaron por presentar valores altos para el estado de salud global y niveles bajos en funcionamiento ( rango = 11.71 a 18.42). El insomnio y el impacto económico fueron las áreas más afectadas. Con el incremento de la edad, se observó menor afectación por síntomas mamarios, función y el disfrute sexual ( r = -.273, -.349 y -.304 respectivamente, p < .01). Conclusión: La situación laboral, estado civil, paridad y lugar de procedencia promovieron afectación diferencial en algunos síntomas incluyendo la imagen corporal. La aplicación de estos cuestionarios permitiría la identificación de necesidades de cuidado físico u emocional en la práctica clínica.
