Impact of cancer-related fatigue on the lives of patients: new findings from the Fatigue Coalition

Type I interferons, inflammation, and fatigue in a longitudinal RNA study of women with breast cancer

BACKGROUND

Fatigue is a common side effect of cancer and its treatment and is thought to be driven in part by activation of the proinflammatory cytokine network. However, the cellular and molecular underpinnings of cancer-related fatigue (CRF) have not been determined, nor have immune pathways beyond inflammation been carefully investigated. The goal of this study was to examine the association between CRF and activation of canonical proinflammatory gene regulation pathways and Type I interferon (IFN) signaling pathways in breast cancer patients during and after treatment.

METHODS

Women diagnosed with early-stage breast cancer (n = 181) completed assessments before and after treatment with radiation and/or chemotherapy and at 6, 12, and 18-month post-treatment follow-ups. Assessments included self-reported fatigue (Multidimensional Fatigue Symptom Inventory - Short Form) and expression of pre-specified sets of Type I IFN and pro-inflammatory immune response genes determined from mRNA sequencing of PBMCs. Mixed effect linear models examined changes in fatigue and immune gene expression over time and tested the hypothesis that fatigue would be associated with increased expression of Type I IFN and inflammatory response genes.

RESULTS

There were significant changes in fatigue and immune gene expression across the assessment period; all measures increased from pre- to post-treatment but showed diverging patterns over the follow-up, with declines in fatigue and persistent elevations in Type I IFN and proinflammatory gene expression. In mixed effect linear models, expression of Type I IFN response genes was elevated in association with fatigue across the assessment period, from pre-treatment to 18-month follow-up. In contrast, pro-inflammatory gene expression was associated with fatigue only at 6, 12, and 18-month follow-ups. Analyses controlling for changes in leukocyte subsets continued to show a significant association between fatigue and Type I IFN gene expression but reduced the time-dependent association with pro-inflammatory gene expression to non-significant.

CONCLUSIONS

Results revealed unexpected complexity in the immune underpinnings of CRF and identify a novel role for IFN signaling as a robust contributor to this symptom before, during, and after treatment. Pro-inflammatory gene expression emerged as a predictor of fatigue later in the cancer trajectory, and that effect was primarily accounted for by a concurrent increase in monocyte prevalence.

Metabolomic profiling of cancer-related fatigue involved in cachexia and chemotherapy

Patients with advanced cancer are frequently burdened with a severe sensation of fatigue called cancer-related fatigue (CRF). CRF is induced at various stages and treatments, such as cachexia and chemotherapy, and reduces the overall survival of patients. Objective and quantitative assessment of CRF could contribute to the diagnosis and prediction of treatment efficacy. However, such studies have not been intensively performed, particularly regarding metabolic profiles. Here, we conducted plasma metabolomics of 15 patients with urological cancer. The patients with and without fatigue, including those with cachexia or chemotherapy-induced fatigue, were compared. Significantly lower concentrations of valine and tryptophan were observed in fatigued patients than in non-fatigued patients. In addition, significantly higher concentrations of polyamine pathway metabolites were observed in patients with fatigue and cachexia than in those without cachexia. Patients with exacerbated fatigue due to chemotherapy showed significantly decreased cysteine and methionine metabolism before chemotherapy compared with those without fatigue exacerbation. These findings suggest that plasma metabolic profiles could help improve the diagnosis and monitoring of CRF.

Incidence of antibody-drug conjugate-related fatigue in patients with breast cancer: A systematic review and meta-analysis

BACKGROUND

Numerous studies have reported the efficacy of antibody-drug conjugates (ADCs) for treating breast cancer. However, during cytotoxic drug treatment, long-term disabling fatigue is common. Moreover, studies in the relevant literature have indicated that fatigue can significantly increase the incidence of depression and sleep disorders. Therefore, this meta-analysis aims to evaluate the incidence of fatigue in breast cancer survivors treated with ADCs.

METHODS

PubMed, EMBASE, Web of Science, and Cochrane Library databases were systematically searched for articles and conference abstracts published before March 16, 2023. Further, two authors independently extracted data from the included studies. The primary outcome of this study was the incidence of all-grade fatigue caused by the use of ADCs in patients with breast cancer. Finally, a random-effects model was used to calculate the incidence and 95% confidence intervals (CIs) of the outcome.

RESULTS

Overall, 7963 patients from 31 studies were included in this meta-analysis to assess the incidence of fatigue caused by the use of approved and marketed ADCs in patients with breast cancer. Notably, the incidence of all-grade fatigue during ADC monotherapy was 39.84% (95% CI, 35.09%-44.69%). In subgroup analyses, among ADCs, the incidence of trastuzumab deruxtecan-induced fatigue was the highest, with an all-grade fatigue incidence of 47.05% (95% CI, 42.38%-51.75%). Meanwhile, the incidence of trastuzumab emtansine (T-DM1)-induced all-grade fatigue was 35.17% (95% CI, 28.87%-41.74%), which was the lowest among ADCs. Further, the incidence of all-grade fatigue due to sacituzumab govitecan was 42.82% (95% CI, 34.54%-51.32%), which was higher than that due to T-DM1. Moreover, the incidence of fatigue was higher with T-DM1 combination therapy than with monotherapy.

CONCLUSIONS

Clinicians have highlighted the high incidence of ADC-related fatigue and its negative impact on patients' physical and mental health, making fatigue an important research variable. The results of this study will further contribute to a comprehensive understanding of ADCs, which have some clinical importance and are of great benefit to patients with breast cancer.

Pulsed Photothermal Therapy of Solid Tumors as a Precondition for Immunotherapy

Photothermal therapy (PTT) refers to the use of plasmonic nanoparticles to convert electromagnetic radiation in the near infrared region to heat and kill tumor cells. Continuous wave lasers have been used clinically to induce PTT, but the treatment is associated with heat-induced tissue damage that limits usability. Here, the engineering and validation of a novel long-pulsed laser device able to induce selective and localized mild hyperthermia in tumors while reducing the heat affected zone and unwanted damage to surrounding tissue are reported. Long-pulsed PTT induces acute necrotic cell death in heat affected areas and the release of tumor associated antigens. This antigen release triggers maturation and stimulation of CD80/CD86 in dendritic cells in vivo that primes a cytotoxic T cell response. Accordingly, long-pulsed PTT enhances the therapeutic effects of immune checkpoint inhibition and increases survival of mice with bladder cancer. Combined, the data promote long-pulsed PTT as a safe and effective strategy for enhancing therapeutic responses to immune checkpoint inhibitors while minimizing unwanted tissue damage.

[The Significance of Chronic Fatigue in the Post-Covid Consultation and its Consequences for Outpatient Rehabilitation in the Context of Statutory Accident Insurance]

OBJECTIVE

The post-COVID consultation (PCC) is offered as part of a comprehensive range of treatment services provided by the statutory accident insurance for post-COVID patients to determine individual recommendations for further care. The aim of the study was to record the main symptoms and the associated restrictions on social and occupational participation in order to derive consequences for outpatient rehabilitation.

METHOD

In addition to a medical examination and a psychological consil, numerous assessments were carried out to evaluate the biopsychosocial state of health. 373 female (82.2%) and 81 male patients aged between 40 and 60 years from the professions of health and care services, education and pedagogy participated in the PCC since April 2021.

RESULTS

Nearly all patients (98.2%) reported fatigue as a cardinal symptom of their post-COVID complaints, in combination with subjectively experienced limitations in brain functioning in over 73% of cases. The duration of the symptomatology persisted for an average of 14-15 months in both female and male insured persons. Thus, over 85% of the total sample can be classified as cases of chronic fatigue (Fatigue Scale). The severity of fatigue also proportionally affects quality of life (SF-36), feelings of anxiety and depression (HADS), psychological resilience (RS-13), and motor parameters such as maximum grip strength and endurance capacity. 54.3% of the patients also received a suspected mental diagnosis and 38.1% a recommendation for further neuropsychological diagnostics.

CONCLUSION

For further treatment of the leading symptom of chronic fatigue, a multimodal and interdisciplinary outpatient rehabilitation is recommended, which should be oriented towards the treatment of the diagnosis of chronic fatigue syndrome (ME/CFS) and thus in particular towards a psychoeducational and rather than a curative therapeutic approach, and should consider aftercare strategies. Confirmed mental disorders and neuropsychological deficits are to be treated in addition.

Potential mechanisms underlying the effect of walking exercise on cancer-related fatigue in cancer survivors

PURPOSE

Cancer-related fatigue (CRF) is a common and debilitating long-term side effect of cancer and its treatment. While exercise has been shown to effectively reduce CRF, the underlying mechanisms are not fully clear. Therefore, the aim of this study was to explore the effects of a 4-month walking exercise program on fatigue severity and to explore potential underlying physiological, behavioral, and psychological mechanisms of action.

METHODS

We included 27 cancer survivors (59 ± 15 years, 37% female) with variable cancer diagnoses who were at least moderately fatigued and finished treatment between 6 and 36 months ago. This study with a quasi-experimental interrupted time-series design compared a 4-month walking intervention period with a 4-month control period. Measurements of fatigue and physiological, behavioral, and psychological factors were performed, supplemented with participants' perceptions on how exercise influenced their fatigue.

RESULTS

A significant and clinically relevant decrease in fatigue severity was found over time (β =  - 8.1, 95% CI =  - 12.1; - 4.2), but could not be attributed directly to the walking exercise intervention. Increases in muscle strength (β =  - 0.07, 95% CI =  - 0.12; - 0.02), physical activity (β =  - 0.1, 95% CI =  - 0.2; - 0.04), and sleep quality (β = 1.1, 95% CI = 0.3; 1.9), as well as decreases in muscle relaxation times (β = 0.09, 95% CI = 0.02; 0.16) and psychological distress (β = 1.1, 95% CI = 0.8; 1.3) were associated with reductions in fatigue severity. Resilience and physical well-being were perceived as most important constructs explaining the walking exercise effects on fatigue.

CONCLUSION

Our findings reveal potential physiological, behavioral, and psychological mechanisms underlying the multidimensional effects of exercise on fatigue severity.

IMPLICATIONS FOR CANCER SURVIVORS

Incorporating resistance exercise and addressing resilience and physical well-being might improve the efficacy of exercise interventions for cancer survivors.

Radiotherapy-induced fatigue in Palestinian breast cancer survivors

Background

No study has investigated the cancer-related fatigue (CRF) among Palestinian breast cancer survivors. Our purpose is to assess, compare, and correlate CRF in breast cancer survivors undergoing radiotherapy (RT) with study variables.

Methods

CRF in breast cancer survivors was assessed using Functional Assessment of Chronic Illness Therapy - Fatigue Scale (FACIT-F) (version 4). The sample consisted of 148 breast cancer survivors undergoing RT. Data was collected between 1 May 2021 and 1 September 2021. The means and standard deviations of the questionnaire using one-way ANOVA, and Pearson correlation coefficient were reported.

Results

Respondents ages ranged from 20 to >65 years old and was divided into four groups: (20-35, 36-50, 51-65, and >65 years, respectively). The total fatigue mean was 2.88 and the SD was 0.84, indicating an intermediate fatigue level among breast cancer survivors. Study survivors with higher education were more likely to be fatigued (F =7.68, P-value =0.001). Divorced survivors were more prone to fatigue compared to married survivors (F =5.83, P-value= 0.001). Finally, survivors who do not have children were more vulnerable to exhaustion compared to those with children (F =7.35, P-value =0.001). Also, younger survivors were more prone to fatigue, compared to older survivors (F =5.29, P-value = 0.002). Results also showed a positive relationship between each of the variables; the number of children (R =0.221, P-value =0.007), age (R =0.311, P-value =0.000), and duration of treatment (R =0.290, P-value =0.000), which means that the greater the number of children, the younger the age, or the longer the duration of treatment, the more fatigue is reported in breast cancer survivors.

Conclusions

Fatigue is frequently observed in breast cancer survivors undergoing RT. It can limit RT treatment continuity. Therefore, early detection of fatigue can help survivors adhere to RT treatment and achieve better clinical results.

Efficacy of Moxibustion for Cancer-Related Fatigue in Patients with Breast Cancer: A Systematic Review and Meta-Analysis

INTRODUCTION

Breast cancer is the most commonly diagnosed cancer worldwide, and most patients experience fatigue. However, there are no effective treatments for cancer-related fatigue (CRF). Several randomized controlled trials (RCTs) have suggested that moxibustion improves CRF. We conducted a systematic review and meta-analysis to compare the differences in fatigue scale scores, quality of life, and clinical efficacy in patients with breast cancer who developed CRF and did versus did not receive moxibustion.

METHODS

RCTs were searched in 7 databases using a standardized search method from database inception to March 2023, and RCTs that met the inclusion criteria were selected.

RESULTS

Among 1337 initially identified RCTs, 10 RCTs involving 744 participants were selected for this study. The meta-analysis involved assessment of the revised Piper Fatigue Scale scores, Cancer Fatigue Scale scores, Karnofsky Performance Scale scores, Athens Insomnia Scale scores, clinical efficacy, and Qi deficiency syndrome scale scores. Compared with the control, moxibustion was associated with significantly better Piper Fatigue Scale scores (P < 0.0001), quality of life [Karnofsky Performance Scale scores (P < 0.0001)], clinical efficacy (P = 0.0007), and Qi deficiency syndrome scale scores (P = 0.02).

CONCLUSIONS

Moxibustion improves CRF in patients with breast cancer. The efficacy of moxibustion should be further examined by high-quality studies in various countries with patients subdivided by their breast cancer treatment status.

A holistic profile for cancer-related fatigue for women with breast cancer - a qualitative study

Objective: Cancer- related fatigue (CRF) is one of the most reported long-term effects after breast cancer and severely impacts quality of life. To come towards optimal treatment of multidimensional CRF, the first step is to use a holistic approach to develop a holistic patient profile including the patient's experience and impact of CRF on their life. Methods and measures: Four semi- structured focus groups with twenty- seven breast cancer patients and fourteen interviews with healthcare professionals (HCPs) were held. Reflexive thematic analysis was used to define (sub)themes for the holistic patient profile. The themes of the interviews and focus groups were compared for validity. Results: Breast cancer patients and HCPs described the same five major themes, consisting of experience of CRF, impact and consequences, coping, personality, and CRF treatment. Experience of CRF consists of cognitive, emotional, and physical aspects. Impact and consequences include work, family, partner relation, social contact and hobbies, body, and misunderstanding. Coping consists of twelve (mal)adaptive strategies. Personality and CRF treatment were summarised as themes. Conclusions: A first holistic patient profile was introduced for CRF for breast cancer. This profile can be conceptualized into a questionnaire to collect information for personalized treatment recommendations and monitoring of CRF over time.

European Portuguese Version of the Multidimensional Fatigue Symptom Inventory-Short Form: Validation Study

INTRODUCTION

Appropriate management of fatigue relies upon comprehensive assessment instruments and timely delivery of targeted interventions. The aims of this study were to translate a commonly used English-language measure of fatigue in cancer patients (the Multidimensional Fatigue Symptom Inventory-Short-Form, or MFSI-SF) into European Portuguese and to evaluate the psychometric properties (internal consistency reliability, factorial structure, and discriminant, convergent and criterion concurrent validity) of the translated measure for use with Portuguese patients.

MATERIAL AND METHODS

After translation and adaptation of the MFSI-SF to European Portuguese, 389 participants (68.38% women), with a mean age of 59.14 years, completed the study protocol. This sample included 148 patients in active cancer treatment from a cancer center and a community sample composed of 55 cancer survivors, 75 patients with other chronic diseases, and 111 healthy controls.

RESULTS

The European Portuguese version of the Multidimensional Fatigue Symptom Inventory-Short Form (IMSF-FR) showed strong internal consistency (Cronbach's alpha = 0.97, McDonald's omega = 0.95). An exploratory factor analysis indicated that the items loaded in a 5-factor model in subscales were similar to the original version. Strong correlations between the IMSF-FR and other measures of fatigue and vitality confirmed convergent validity. Discriminant validity was supported by weak-to-moderate correlations between the IMSF-FR and measures of sleepiness, propensity to sleep, and lapses of attention and memory. The IMSF-FR accurately distinguished cancer patients from healthy controls and was able to differentiate clinician rated levels of performance among cancer patients.

CONCLUSION

The IMFS-FR is a reliable and valid tool to assess cancer-related fatigue. By providing integrated comprehensive characterization of fatigue, this instrument may assist clinicians implementing targeted interventions.

Effects of exercise training on cancer patients undergoing neoadjuvant treatment: A systematic review

OBJECTIVES

This systematic review aimed to analyze the effects of different exercise protocols on physical fitness (cardiorespiratory fitness, muscle strength, and body composition), quality of life, cancer-related fatigue, and sleep quality in patients with different types of cancer undergoing neoadjuvant treatment.

DESIGN

Systematic review.

METHOD

A comprehensive search of existing literature was carried out using four electronic databases: PubMed, Scopus, Web of Science, and Cochrane Library (published until October 19, 2022). All databases were searched for randomized controlled trials, quasi-experimental investigations, and pre-post investigations assessing the effects of exercise in cancer patients during neoadjuvant treatment. Excluded articles included multicomponent interventions, such as exercise plus diet or behavioral therapy, and investigations performed during adjuvant treatment or survivorship. The methodological quality of each study was assessed using the Physiotherapy Evidence Database (PEDro) scale.

RESULTS

Twenty-seven trials involving 999 cancer patients were included in this review. The interventions were conducted in cancer patients undergoing neoadjuvant treatment for rectal (n = 11), breast (n = 5), pancreatic (n = 4), esophageal (n = 3), gastro-esophageal (n = 2), and prostate (n = 1) cancers, and leukemia (n = 1). Among the investigations included, 14 utilized combined exercise protocols, 11 utilized aerobic exercise, and two utilized both aerobic and resistance training separately. Exercise interventions appeared to improve cardiorespiratory fitness, muscle strength, body composition, and quality of life, although many investigations lacked a between-group analysis.

CONCLUSION

Despite limited evidence, exercise interventions applied during neoadjuvant treatment demonstrate promising potential in enhancing cardiorespiratory fitness, muscle strength, body composition, and overall quality of life. However, a scarcity of evidence remains on the effects of exercise on cancer-related fatigue and sleep quality. Further research with high-quality randomized controlled trials is warranted.

The long-term course and relationship with survival of multidimensional fatigue in patients with brain metastases after Gamma Knife radiosurgery

PURPOSE

The aims of this study were to evaluate long-term multidimensional fatigue in patients with brain metastases (BM) up to 21 months after Gamma Knife radiosurgery (GKRS) and (change in) fatigue as predictor of survival.

METHODS

Patients with 1 to 10 BM, expected survival > 3 months, and Karnofsky Performance Status ≥ 70, and Dutch non-cancer controls were included. Fatigue was measured with the Multidimensional Fatigue Inventory. Levels of fatigue between patients and controls were compared using independent-samples t-tests. Linear mixed models were used to evaluate fatigue within the patient group up to 21 months after GKRS. Pre-GKRS fatigue and minimal clinically important (MCI) changes in fatigue in the first three months (defined as a 2-point difference) after GKRS were evaluated as predictors of survival time.

RESULTS

Prior to GKRS, patients with BM (n = 92) experienced significantly higher fatigue on all subscales than controls (n = 104). Over 21 months, physical fatigue increased, and mental fatigue decreased significantly. More specifically, general, and physical fatigue increased significantly between pre-GKRS and 3 months, followed by stable scores between 3 (n = 67) and 6 (n = 53), 6 and 12 (n = 34) and 12 and 21 (n = 21) months. An MCI increase in general or physical fatigue over the first 3 months after GKRS was a significant predictor of shorter survival time.

CONCLUSION

Except for mental fatigue, all aspects of fatigue remained elevated or further increased up to 21 months after treatment. Furthermore, an increase in general or physical fatigue within three months after GKRS may be a prognostic indicator for poorer survival.

Effects of High-Intensity Interval Training and Combined High-Intensity Interval Training Programs on Cancer-Related Fatigue and Cancer Pain: A Systematic Review and Meta-analysis

PURPOSE

This systematic review and meta-analysis assessed the effectiveness of high-intensity interval training (HIIT) alone and combined HIIT programs compared with usual care on cancer-related fatigue (CRF) and pain related to cancer or cancer-related treatments.

METHODS

Articles published prior to January 2023 were searched in the following digital databases: PubMed, Cochrane Database of Systematic Reviews and Cochrane Controlled Clinical Trials (CENTRAL), Web of Science, Scopus and ScienceDirect. Randomized controlled trials were included that met the following criteria: (i) adult cancer patients and survivors (>18 yr old); (ii) HIIT or combined HIIT programs versus usual care; (iii) assessment of fatigue and pain. Cochrane tool was used for assessing Risk of Bias (RoB) and Review Manager (RevMan 5.2) was used for data analysis.

RESULTS

Based on limited number (12) of studies included, we found HIIT and combined HIIT interventions have significant effect sizes on reducing both CRF (standardized mean difference, 0.63; 95% confidence interval, 0.42-0.84; P < 0.001) and cancer-associated pain (standardized mean difference, 0.44; 95% confidence interval, 0.25-0.63; P < 0.001).

CONCLUSIONS

This systematic review and meta-analysis indicate that HIIT and combined HIIT programs can reduce CRF and pain.

The association of cancer-related fatigue on the social, vocational and healthcare-related dimensions of cancer survivorship

BACKGROUND

Cancer-related fatigue (CRF) is well documented in cancer survivors, but little is known about the personal and societal impact of CRF. This study aimed to examine the impact of CRF in relation to social and vocational functioning and health care utilization in a large sample of post-treatment cancer survivors.

METHODS

We conducted a cross-sectional descriptive study of early stage breast and colorectal cancer survivors (n = 454) who were within 5 years from treatment completion. Social difficulties (SDI-21), work status, absenteeism and presenteeism (WHO-HPQ) and healthcare utilization (HSUQ) were compared in those with (CFR +) and without (CRF -) clinically significant fatigue (FACT-F ≤ 34).

RESULTS

A total of 32% met the cut-off criteria for CRF (≤ 34). Participants with CRF + had significantly higher scores on the SDI-21 across all domains and 55% of CRF + vs. 11% in CRF - was above the SDI cut-off (> 10) for significant social difficulties. Participants with CRF + were 2.74 times more likely to be unemployed or on leave (95% CI 1.62, 4.61, p < 0.001). In the subgroup of participants who were currently working (n = 249), those with CRF + reported working on average 27.4 fewer hours in the previous 4 weeks compared to CRF - (p = 0.05), and absolute presenteeism was on average 13% lower in the CRF + group (95% CI 8.0, 18.2, p < 0.001). Finally, individuals with CRF + reported significantly more physician (p < 0.001), other health care professional (p = 0.03) and psychosocial visits (p = 0.002) in the past month.

CONCLUSIONS AND IMPLICATIONS FOR CANCER SURVIVORS

CRF is associated with substantial disruption in social and work role functioning in the early transitional phase of cancer survivorship. Better management of persistent CRF and funding for the implementation of existing guidelines and recommended evidence-based interventions are urgently needed.

Prediction Model for Postoperative Quality of Life Among Breast Cancer Survivors Along the Survivorship Trajectory From Pretreatment to 5 Years: Machine Learning-Based Analysis

BACKGROUND

Breast cancer is the most common cancer and the most common cause of cancer death in women. Although survival rates have improved, unmet psychosocial needs remain challenging because the quality of life (QoL) and QoL-related factors change over time. In addition, traditional statistical models have limitations in identifying factors associated with QoL over time, particularly concerning the physical, psychological, economic, spiritual, and social dimensions.

OBJECTIVE

This study aimed to identify patient-centered factors associated with QoL among patients with breast cancer using a machine learning (ML) algorithm to analyze data collected along different survivorship trajectories.

METHODS

The study used 2 data sets. The first data set was the cross-sectional survey data from the Breast Cancer Information Grand Round for Survivorship (BIG-S) study, which recruited consecutive breast cancer survivors who visited the outpatient breast cancer clinic at the Samsung Medical Center in Seoul, Korea, between 2018 and 2019. The second data set was the longitudinal cohort data from the Beauty Education for Distressed Breast Cancer (BEST) cohort study, which was conducted at 2 university-based cancer hospitals in Seoul, Korea, between 2011 and 2016. QoL was measured using European Organization for Research and Treatment of Cancer QoL Questionnaire Core 30 questionnaire. Feature importance was interpreted using Shapley Additive Explanations (SHAP). The final model was selected based on the highest mean area under the receiver operating characteristic curve (AUC). The analyses were performed using the Python 3.7 programming environment (Python Software Foundation).

RESULTS

The study included 6265 breast cancer survivors in the training data set and 432 patients in the validation set. The mean age was 50.6 (SD 8.66) years and 46.8% (n=2004) had stage 1 cancer. In the training data set, 48.3% (n=3026) of survivors had poor QoL. The study developed ML models for QoL prediction based on 6 algorithms. Performance was good for all survival trajectories: overall (AUC 0.823), baseline (AUC 0.835), within 1 year (AUC 0.860), between 2 and 3 years (AUC 0.808), between 3 and 4 years (AUC 0.820), and between 4 and 5 years (AUC 0.826). Emotional and physical functions were the most important features before surgery and within 1 year after surgery, respectively. Fatigue was the most important feature between 1 and 4 years. Despite the survival period, hopefulness was the most influential feature on QoL. External validation of the models showed good performance with AUCs between 0.770 and 0.862.

CONCLUSIONS

The study identified important factors associated with QoL among breast cancer survivors across different survival trajectories. Understanding the changing trends of these factors could help to intervene more precisely and timely, and potentially prevent or alleviate QoL-related issues for patients. The good performance of our ML models in both training and external validation sets suggests the potential use of this approach in identifying patient-centered factors and improving survivorship care.

Effectiveness of Therapeutic Exercise Models on Cancer-Related Fatigue in Patients With Cancer Undergoing Chemotherapy: A Systematic Review and Network Meta-analysis

OBJECTIVE

To assess and compare the effectiveness of different exercise modalities in reducing cancer-related fatigue (CRF) in patients with cancer undergoing chemotherapy. Exercise intensities for selected exercise types were also compared.

DATA SOURCES

We conducted a search in MEDLINE, Embase, CINAHL, Scopus, SPORTDiscus, and Web of Science from inception to October 15, 2021.

STUDY SELECTION

Randomized controlled trials concerning the effectiveness of exercise modalities on CRF in patients with cancer undergoing chemotherapy were included.

DATA EXTRACTION

Study characteristics were extracted using a structured protocol. Methodological quality was assessed employing the PEDro scale and risk of bias was assessed using the Revised Cochrane Risk of Bias Tool for Randomized Trials. The certainty of evidence was assessed based on Grading of Recommendations, Assessment, Development and Evaluation. The measure of effect used was the adjusted standardized mean difference (SMD) or Hedge's g, together with the corresponding 95% confidence intervals (CI).

DATA SYNTHESIS

Forty-seven studies were included. Data were pooled employing a random-effects model. There was a trend that adding low-intensity aerobic and resistance exercise (SMD=1.28, 95% CI -0.18; 2.75, P=.086), or moderate-intensity aerobic and resistance exercise (SMD=0.85; 95% CI -0.12; 1.82, P=.087), was more effective than adding flexibility training to usual care (UC). There was also a trend that UC alone was less effective than adding moderate-intensity aerobic and resistance exercise (SMD=-0.47, 95% CI -0.96, 0.02, P=.060) to UC.

CONCLUSIONS

The addition of low- to moderate-intensity aerobic and/or resistance exercise demonstrated a positive trend for improvement in CRF in patients with cancer undergoing chemotherapy, when compared with UC alone or UC with flexibility training.

Distress Disorder Histories Relate to Greater Physical Symptoms Among Breast Cancer Patients and Survivors: Findings Across the Cancer Trajectory

BACKGROUND

Psychological disorders can substantially worsen physical symptoms associated with breast cancer diagnosis and treatment, reducing survivors' quality of life and increasing recurrence risk. Distress disorders may be particularly detrimental given their physical correlates. Across two studies, we examined the relationship between a distress disorder history and physical symptoms pre- and post-adjuvant treatment - two important periods of the cancer trajectory.

METHODS

Breast cancer patients awaiting adjuvant treatment (n = 147; mean age = 52.54) in study 1 and survivors 1-10 years post-treatment (n = 183; mean age = 56.11) in study 2 completed a diagnostic interview assessing lifetime presence of psychological disorders. They also rated their pain, fatigue, physical functioning, and self-rated health. Covariates included body mass index, age, cancer stage, menopause status, and physical comorbidities.

RESULTS

Results from both studies indicated that a distress disorder history was associated with higher pain, fatigue, and sleep difficulties as well as lower self-rated health compared to those without such a history.

CONCLUSIONS

These findings suggest that breast cancer survivors with a distress disorder may be particularly at risk for more physical symptoms, poorer sleep, and worse self-rated health both prior to and following adjuvant treatment.

Evaluating the impact of patients' psychological and physical problems on their interest in participating in research at a cancer center with a rural catchment area

BACKGROUND

Cancer patients' participation in research trials is essential to improving their care and treatment. In a large sample of adults recently diagnosed with cancer, the aim of the current study is to investigate the relationship between cancer patients' interest in research and the psychological and physical problems they experience resulting from their cancer diagnosis.

METHOD

We analyzed data from 906 cancer patients collected during routine clinical care. Correlational analyses focused on the relationship between patients' psychological and physical problems and their interest in research. Hierarchical binary logistic regression analyses tested whether patients' psychological/physical problems as a block predicted their interest in research, above and beyond their sociodemographic characteristics.

RESULTS

Higher levels of patients' anxiety, fear of cancer treatment, difficulty managing emotions, worry, suicidal/homicidal ideation, fatigue, problems related to physical appearance, sleep difficulty, and changes to weight/appetite, were associated with a greater interest in research. Patients' psychological/physical problems, as a block, incrementally predicted their interest in research (Δχ2 = 24.34, df = 14, p = .04, Δr2=0.05), though none of the individual psychological/physical problems were found to be significant predictors. A higher level of education was significantly positively associated with an increased likelihood of being interested in research (OR = 1.26, 95%CI = 1.09, 1.46, p = .001).

CONCLUSION

Cancer patients' problems stemming from their diagnosis can be important factors in their decision to participate in research. Depending on the needs of the trial in question, researchers may want to account for patients' level of symptom burden in deciding who to approach for enrollment in a research trial.

Sexual Dimorphism of Skeletal Muscle in a Mouse Model of Breast Cancer: A Functional and Molecular Analysis

Breast cancer incidence in men is statistically rare; however, given the lack of screening in males, more advanced stages at initial diagnosis result in lower 5-year survival rates for men with breast cancer compared to women. A sexual dimorphism, with respect to the effect of tumor growth on cachexia incidence and severity, has also been reported across cancer types. The purpose of this study was to examine the sexual dimorphism of breast cancer as it pertains to skeletal muscle function and molecular composition. Using female and male transgenic PyMT mice, we tested the hypothesis that the isometric contractile properties and molecular composition of skeletal muscle would be differentially affected by breast tumors. PyMT tumor-bearing mice of each sex, corresponding to maximal tumor burden, were compared to their respective controls. RNA sequencing of skeletal muscle revealed different pathway alterations that were exclusive to each sex. Further, differentially expressed genes and pathways were substantially more abundant in female tumor mice, with only minimal dysregulation in male tumor mice, each compared to their respective controls. These differences in the transcriptome were mirrored in isometric contractile properties, with greater tumor-induced dysfunction in females than male mice, as well as muscle wasting. Collectively, these data support the concept of sexually dimorphic responses to cancer in skeletal muscle and suggest that these responses may be associated with the clinical differences in breast cancer between the sexes. The identified sex-dependent pathways within the muscle of male and female mice provide a framework to evaluate therapeutic strategies targeting tumor-associated skeletal muscle alterations.

Massage therapy significantly improves cancer-related fatigue in cancer patients: a meta-analysis of randomized controlled trials

PURPOSE

This study was designed to investigate the effectiveness and safety of massage therapy in cancer-related fatigue (CRF) and to provide a reference for the future management of CRF.

METHODS

Eight databases (PubMed, Embase, Cochrane Library, CINAHL, Sinomed, Chinese Scientific Journal database (VIP), Wanfang, and China National Knowledge Infrastructure (CNKI)) were systematically reviewed from inception to May 2022 for randomized controlled trials. Two reviewers critically and independently assessed the risk of bias using Cochrane Collaboration criteria and extracted correlated data using the designed form. The meta-analysis was performed using RevMan 5.3 to calculate the pooled effect sizes and 95% confidence intervals (CIs). Sensitivity analysis was performed to find the source of the heterogeneity. Publication bias was assessed via funnel plot analysis and the Egger test.

RESULT

A total of 11 qualified studies that included 789 patients (massage therapy group: 389; control group: 400) were included in the meta-analysis. Massage therapy had a marked effect on fatigue in cancer patients [standardized mean difference (SMD) =  - 1.69, 95% CI (- 2.46, - 0.93), P < 0.01], especially in breast cancer [SMD =  - 1.62, 95% CI (- 2.18, - 1.05), P < 0.01]. Reflexology [SMD =  - 2.71, 95% CI (- 4.65, - 0.77), P < 0.01] and Chinese massage [SMD =  - 1.14, 95% CI (- 1.95, - 0.33), P < 0.01] can have a more significant effect on fatigue. Massage time is 20 to 40 min [SMD =  - 2.39, 95% CI (- 4.13, - 0.66), P < 0.01], twice a week [SMD =  - 3.46, 95% CI (- 5.47, - 1.45), P < 0.01] for 3-5 weeks [SMD =  - 2.36, 95% CI (- 3.53, - 1.19), P < 0.01], which is more effective in relieving fatigue in cancer patients. Five studies described the occurrence of adverse events and only two studies had adverse events.

CONCLUSION

Massage therapy can be effective in relieving fatigue in cancer patients. Current evidence suggests that reflexology is the most effective approach to relieve fatigue, particularly in the breast cancer patients. The optimal intervention frequency and cycle for massage therapy is twice a week for 3-5 weeks, and the optimal duration is 20-40 min.

Self-perception of fatigue in individuals diagnosed with head and neck cancer

PURPOSE

Head and neck cancer (HNCa) presents numerous challenges secondary to treatment. While there is substantial clinical awareness to the range of challenges demonstrated in this population, information on the impact of post-treatment fatigue is limited. This study investigated the degree of perceived fatigue in those treated for HNCa.

METHODS

The study was a cross-sectional, self-report, survey design. Adult participants (n = 47) completed a series of three questionnaires; two validated fatigue measures - the Fatigue Screening Inventory (FSI) and the Multidimensional Fatigue Inventory (MFI-20) and a general health-related quality of life measure the European Organisation of Research on the Treatment of Cancer - Quality of Life Questionnaire (EORTC-QLQC30) and the head and neck site specific module (QLQ - H&N 35) were administered.

RESULTS

Of the 47 participants, more than half (55%) were identified as having clinically significant self-reported levels of fatigue. Correlational analysis revealed an inverse relationship between fatigue and overall health-related quality of life (HRQOL) implying that as fatigue increases, one's perceived HRQOL decreases.

CONCLUSIONS

These data suggest that efforts to proactively screen for and index fatigue and seek anticipatory interventions may benefit both short- and long-term HRQOL outcomes in those diagnosed with HNCa.

Exercise improves the outcome of anticancer treatment with ultrasound-hyperthermia-enhanced nanochemotherapy and autophagy inhibitor

It has been shown that exercise has a direct impact on tumor growth along with functional improvement. Previous studies have shown that exercise decreases the risk of cancer recurrence across various types of cancer. It was indicated that exercise stimulates the immune system to fight cancer. Previous study demonstrated that pulsed-wave ultrasound hyperthermia (pUH) combined with PEGylated liposomal doxorubicin (PLD) and chloroquine (CQ) inhibits 4T1 tumors growth and delays their recurrence. In this study, we investigated if the combinatorial treatment with high-intensity interval training (HIIT) combined with pUH-enhanced PLD delivery and CQ improved the outcome. The mouse experiment composed of three groups, HIIT+PLD+pUH+CQ group, PLD+pUH+CQ group, and the control group. HIIT+PLD+pUH+CQ group received 6 weeks of HIIT (15 min per day, 5 days per week) before 4T1 tumor implantation. Seven days later, they received therapy with PLD (10 mg/kg) + pUH (3 MHz, 50% duty cycle, 0.65 W/cm2, 15min) + CQ (50 mg/kg daily). Results showed that HIIT+PLD+pUH+CQ significantly reduced the tumor volumes and brought about longer survival of tumor-bearing mice than PLD+pUH+CQ did. Blood cell components were analyzed and showed that neutrophil and reticulocytes decreased while lymphocytes increased after exercise.

State of research, feasibility, safety, acceptability, and outcomes examined on remotely delivered exercises using technology for older adult with cancer: a scoping review

INTRODUCTION

Technology-based exercise is gaining attention as a promising strategy for increasing physical activity (PA) in older adults with cancer (OACA). However, a comprehensive understanding of the interventions, their feasibility, outcomes, and safety is limited. This scoping review (1) assessed the prevalence and type of technology-based remotely delivered exercise interventions for OACA and (2) explored the feasibility, safety, acceptability, and outcomes in these interventions.

METHODS

Studies with participant mean/median age ≥ 65 reporting at least one outcome measure were included. Databases searched included the following: PubMed, CINAHL, Embase, Cochrane Library Online, SPORTDiscus, and PsycINFO. Multiple independent reviewers completed screening and data abstractions of articles in English, French, and Spanish.

RESULTS

The search yielded 2339 citations after removing duplicates. Following title and abstract screening, 96 full texts were review, and 15 were included. Study designs were heterogeneous, and sample sizes were diverse (range 14-478). The most common technologies used were website/web portal (n = 6), videos (n = 5), exergaming (n = 2), accelerometer/pedometer with video and/or website (n = 4), and live-videoconferencing (n = 2). Over half (9/15) of the studies examined feasibility using various definitions; feasibility outcomes were reached in all. Common outcomes examined include lower body function and quality of life. Adverse events were uncommon and minor were reported. Qualitative studies identified cost- and time-savings, healthcare professional support, and technology features that encourage engagement as facilitators.

CONCLUSION

Remote exercise interventions using technology appear to be feasible and acceptable in OACA.

IMPLICATIONS FOR CANCER SURVIVORS

Some remote exercise interventions may be a viable way to increase PA for OACA.

Understanding Sleep Disturbances in Prostate Cancer-A Scientometric Analysis of Sleep Assessment, Aetiology, and Its Impact on Quality of Life

Prostate cancer is the most commonly diagnosed cancer in the United Kingdom. While androgen-deprivation therapy is the most common treatment for prostate cancer, patients undergoing this treatment typically experience side effects in terms of sleep disturbances. However, the relation between prostate cancer and sleep and the way in which sleep interventions may benefit oncological patients is underinvestigated in the literature. The current study aims to review in a data-driven approach the existing literature on the field of prostate cancer and sleep to identify impactful documents and major thematic domains. To do so, a sample of 1547 documents was downloaded from Scopus, and a document co-citation analysis was conducted on CiteSpace software. In the literature, 12 main research domains were identified as well as 26 impactful documents. Research domains were examined regarding the link between prostate cancer and sleep, by taking into account variations in hormonal levels. A major gap in the literature was identified in the lack of use of objective assessment of sleep quality in patients with prostate cancer.

Development Trajectories of Fatigue, Quality of Life, and the Ability to Work among Colorectal Cancer Patients in the First Year after Rehabilitation-First Results of the MIRANDA Study

Cancer-related fatigue, low quality of life (QoL), and low ability to work are highly prevalent among colorectal cancer (CRC) patients after tumor surgery. We aimed to analyze their intercorrelations and trajectories in the first year after in-patient rehabilitation in the German multicenter MIRANDA cohort study. Recruitment is ongoing, and we included the first 147 CRC patients in this analysis. Participants filled out questionnaires at the beginning of in-patient rehabilitation (baseline) and at 3, 6, 9, and 12 months after the baseline. The EORTC-QLQ-C30-General-Health-Status (GHS)/QoL, the FACIT-F-Fatigue Scale, and the FACIT-F-FWB-ability-to-work items were used to evaluate QoL, fatigue, and ability to work, respectively. The fatigue and QoL scales were highly correlated (r = 0.606). A moderate correlation was observed between the fatigue and ability to work scales (r = 0.487) and between the QoL and ability to work scales (r = 0.455). Compared to the baseline, a statistically significant improvement in the QoL, ability to work, and fatigue scales were observed at the 3-month follow-up (Wilcoxson signed rank test, all p < 0.0001). The three scales plateaued afterward until the 12-month follow-up. In conclusion, fatigue, QoL, and ability to work were highly interrelated, improved quickly during/after in-patient rehabilitation, and did not change much afterward in German CRC patients.

Sexual Dimorphism of Skeletal Muscle in a Mouse Model of Breast Cancer: A Functional and Molecular Analysis

Breast cancer incidence in men is statistically rare; however, given the lack of screening in males, more advanced stages at initial diagnosis results in lower 5-year survival rates for men with breast cancer compared to women. A sexual dimorphism, with respect to the effect of tumor growth on cachexia incidence and severity, has also been reported across cancer types. The purpose of this study was to examine the sexual dimorphism of breast cancer as it pertains to skeletal muscle function and molecular composition. Using female and male transgenic PyMT mice, we tested the hypothesis that isometric contractile properties and molecular composition of skeletal muscle would be differentially affected by breast tumors. PyMT tumor-bearing mice of each sex, corresponding to maximal tumor burden, were compared to their respective controls. RNA-sequencing of skeletal muscle revealed different pathway alterations that were exclusive to each sex. Further, differentially expressed genes and pathways were substantially more abundant in female tumor mice, with only minimal dysregulation in male tumor mice, each compared to their respective controls. These differences in the transcriptome were mirrored in isometric contractile properties, with greater tumor-induced dysfunction in females than male mice, as well as muscle wasting. Collectively, these data support the concept of sexually dimorphic responses to cancer in skeletal muscle and suggest these responses may be associated with the clinical differences in breast cancer between the sexes. The identified sex-dependent pathways within muscle of male and female mice provide a framework to evaluate therapeutic strategies targeting tumor-associated skeletal muscle alterations.

Active for Life after Cancer: Association of Physical Activity with Cancer Patients' Interpersonal Competence, Quality of Life, and Survival Beliefs

This study aimed to examine the relationship between physical activity and cancer patients' survival beliefs and constructed a mediation model involving the mediating effects of interpersonal competence and quality of life. We conducted 252 questionnaire surveys on multiple chat groups for cancer patients using the WeChat software, and assessed physical activity, survival beliefs, interpersonal competence, and quality of life using standard scales. Data were analyzed using SPSS and AMOS. There were positive correlations between physical activity and quality of life (β = 0.393, p < 0.001), physical activity and interpersonal competence (β = 0.385, p < 0.001), interpersonal competence and quality of life (β = 0.455, p < 0.001), and quality of life and survival beliefs (β = 0.478, p < 0.001). In addition, a significant mediating effect between physical activity and survival beliefs was observed between interpersonal competence and quality of life (standardized indirect effect = 0.384, p < 0.001). The study revealed that effective physical activity led to higher interpersonal competence, more excellent quality of life, and improved survival beliefs in cancer patients, and that the association of physical activity with improved survival beliefs was fully mediated through interpersonal competence and quality of life. The findings suggest that the relevant government should increase policy support and publicity to improve cancer patients' participation in physical activity.

Mechanisms of trastuzumab induced cardiotoxicity - is exercise a potential treatment?

The use of the adjuvant therapeutic antibody trastuzumab in breast cancer is associated with a range of cardiotoxic side effects despite successfully reducing the severity of outcomes cancer patients,. The most common cardiac effect, a reduction in left ventricular ejection fraction (LVEF), is a known precursor to heart failure and often requires interruption of chemotherapy to avoid endangering patients further. An understanding of trastuzumab's cardiac-specific interactions is therefore critical in devising new methods to not only avoid permanent cardiac damage, but also prolong treatment time, and therefore effectiveness, for breast cancer patients. Increasingly, the use of exercise as a treatment has been indicated across the field of cardio-oncology due to encouraging evidence that it can protect against LVEF reductions and heart failure. This review explores the mechanisms of trastuzumab-mediated cardiotoxicity, as well as the physiological effects of exercise on the heart, in order to assess the suitability of exercise intervention for breast cancer patients on trastuzumab antibody-therapy. We furthermore draw comparison to existing evidence for exercise intervention as a cardioprotective treatment in doxorubicin-induced cardiotoxicity. Although preclinical evidence seems to support exercise-based approaches also in trastuzumab-cardiotoxicity, current clinical evidence is too limited to confidently recommend it as a treatment, largely owing to issues of adherence. Future studies should therefore examine how the variety and duration of exercise can be adjusted to improve treatment effectiveness at a more personalised level.

Characteristics of Cancer-Related Fatigue and an Efficient Model to Identify Patients with Gynecological Cancer Seeking Fatigue-Related Management

Cancer-related fatigue (CRF) is the most common somatic discomfort in patients with gynecological cancers. CRF is often overlooked; however, it can impair the patients’ quality of life considerably. This cross-sectional study aimed to identify the clinical characteristics of CRF in gynecological cancer patients. Questionnaires and the International Classification of Diseases 10th Revision (ICD-10) criteria were used to identify CRF. The enrolled patients were further categorized according to the amount of fatigue-related management received. Of the enrolled 190 patients, 40.0% had endometrial cancer, 28.9% had cervical cancer, and 31.1% had ovarian cancer. On the basis of the ICD-10 diagnostic criteria, 42.6% had non-cancer-related fatigue, 10% had CRF, and 51% had BFI-T questionnaire-based fatigue. Moreover, 77.9% of the study cohort had ever received fatigue-related management. Further analysis showed that patients with endometrial/cervical cancer, International Federation of Gynecology and Obstetrics stage >1, Eastern Cooperative Oncology Group performance status score ≥1, inadequate cancer treatment response, and receiving cancer treatment in the past week had a higher probability of receiving more fatigue-related management. The five-item predictive model developed from these factors may help physicians recognize patients seeking more fatigue-related management more efficiently. This is important as they may suffer from a more profound CRF.

Navigating severe chronic cancer-related fatigue: an interpretative phenomenological analysis

OBJECTIVE

This article presents a phenomenological study on the embodied experiences of patients with Chronic Cancer-Related Fatigue (CCRF), aiming to better understand this complex phenomenon.

DESIGN

Data collection consisted of individual interviews with 25 participants who suffered from severe CCRF for at least three months after cancer treatment was finished.

MAIN OUTCOME MEASURES

Against the theoretical background of philosophical phenomenology, we explored embodied experiences, incorporated temporal and spatial aspects of living with CCRF. We applied interpretative phenomenological analysis (IPA) to analyze the transcripts of the interviews.

RESULTS

Using IPA, we identified four themes on how chronic fatigue is experienced post-cancer: (1) Worn out; (2) Diminishment of one's 'I can'; (3) Invisibility; and (4) Regaining one's 'I can'.

CONCLUSION

For clinical practice, these results imply that professionals could focus more on the role of the body and limitations of one's 'I can' when treating CCRF. By studying these embodied CCRF experiences in individual patients, future research could help personalize and optimize treatment.

Psychosocial Interventions for the Treatment of Cancer-Related Fatigue: An Umbrella Review

Cancer-related fatigue is one of the most common symptoms of cancer and one of those referred by patients as the most disabling. However, we still do not have enough evidence to allow us to recommend effective and personalized approaches. Goal: To provide evidence on the efficacy of ASCO-recommended psychosocial interventions for reducing cancer-related fatigue. Methodology: A general quantitative systematic review for nonprimary clinical interventions that allows the collection, synthesis and analysis of already published reviews. Systematic reviews of RTCs were selected as these make up the body of knowledge that provides the most evidence in an umbrella format. The results do not provide clear or comparable evidence regarding the different interventions, with moderate evidence standing out for cognitive interventions and mindfulness. Conclusions: Research gaps, study biases and the need for further research to ask more precise questions and to make reliable recommendations to mitigate the impact of cancer-related fatigue are evident.

Addressing cancer-related fatigue through sleep: A secondary analysis of a randomized trial comparing acupuncture and cognitive behavioral therapy for insomnia

Background

Fatigue is a troublesome symptom in cancer survivors that often results from disrupted sleep. We sought to assess whether two insomnia-focused non-pharmacological interventions are also effective for improving fatigue.

Methods

We analyzed data from a randomized clinical trial comparing cognitive behavioral therapy for insomnia (CBT-I) versus acupuncture for insomnia among cancer survivors. Participants were 109 patients who reported insomnia and moderate or worse fatigue. Interventions were delivered over eight weeks. Fatigue was evaluated at baseline, week 8, and week 20 using the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). We used both mediation analysis and t-tests to explore the extent to which fatigue reduction was attributable to insomnia response.

Results

Compared to baseline, both CBT-I and acupuncture produced significant reductions in total MFSI-SF scores at week 8 (-17.1 points; 95% confidence interval [CI]: -21.1 to -13.1, and -13.2 points; 95% CI: -17.2 to -9.2, respectively, all p<0.001) and week 20 (-14.6 points; 95% CI: -18.6 to -10.6, and -14.2 points; 95% CI: -18.1 to -10.3. respectively, all p<0.001), with no significant between-group differences. MFSI-SF total scores at week 8 were significantly associated with sleep improvements in both CBT-I and acupuncture groups (p<0.001 and p=0.011, respectively). Insomnia responders demonstrated significantly greater improvements in mean MFSI-SF total scores compared with non-responders in the CBT-I group (p=0.016) but not in the acupuncture group.

Conclusion

CBT-I and acupuncture produced similar, clinically meaningful, and durable fatigue reductions in cancer survivors with insomnia, primarily through improvements in sleep. Acupuncture may also reduce fatigue through additional pathways.

Treatment of Cancer-related-Fatigue in Acute Hematological Malignancies: Results of a Feasibility Study of using Cognitive Behavioral Therapy

BACKGROUND

Despite cancer related fatigue (CRF) being the most common, and debilitating symptom in patients with recently diagnosed acute hematological malignancies (HM), there are limited effective treatments for CRF in HM. The aim of this study was to determine the feasibility of cognitive behavioral therapy (CBT) for CRF in HM.

METHODS

In this preliminary longitudinal prospective study, HM patients diagnosed a median of one month previously with moderate to severe fatigue were enrolled. Patients received CBT in seven weekly sessions for eight weeks. Change in Functional Assessment of Cancer Illness Therapy (FACIT) - Fatigue (primary), FACT-G, Pittsburg Sleep Quality Index (PSQI), Hospital Anxiety Depression Scale (HADS), M.D. Anderson Symptom Inventory - Acute Myeloid Leukemia (MDASI-AML/MDS), and Herth Hope Index (HHI) were analyzed.

RESULTS

Twenty-seven of 36 (75 %) patients were evaluable. Adherence and satisfaction rates to the CBT intervention were 78.6% (95% CI 67.2%, 89.9%), and 92% (95% CI 76.7%, 98.3%) respectively. The median age 66, 64% female, the most common HM was AML (60%), median FACIT-F was 27. The mean (SD) improvement at end eight weeks for FACIT-F was 5.5(13.6), Cohen δ 0.4, P=0.046; and for PSQI total was 2.9 (3), Cohen δ -1, P=0.006. We also found significant improvement in HADS anxiety -2.7(4.5), P=0.049, MDASI Sleep -1.8(3.0), P=0.022, MDASI mean module symptom severity -0.7(1.6), P=0.006. However, no significant improvements were found in FACT-G, HHI, and HADS-depression scores.

CONCLUSIONS

The use of CBT was feasible with improvement of CRF, sleep quality, and anxiety scores in HM. Randomized controlled trials are justified.

Effect of Yoga and Mediational Influence of Fatigue on Walking, Physical Activity, and Quality of Life Among Cancer Survivors

BACKGROUND

Cancer-related fatigue (CRF) negatively affects survivors' walking, engagement in physical activity (PA), and quality of life (QoL). Yoga is an effective therapy for treating CRF; however, evidence from large clinical trials regarding how reducing CRF through yoga influences CRF's interference with survivors' walking, engagement in PA, and QoL is not available. We examined the effects of yoga and the mediational influence of CRF on CRF's interference with walking, PA, and QoL among cancer survivors in a multicenter phase III randomized controlled trial.

PATIENTS AND METHODS

Cancer survivors (n=410) with insomnia 2 to 24 months posttreatment were randomized to a 4-week yoga intervention-Yoga for Cancer Survivors (YOCAS)-or standard care. A symptom inventory was used to assess how much CRF interfered with survivors' walking, PA, and QoL. The Multidimensional Fatigue Symptom Inventory-Short Form was used to assess CRF. Two-tailed t tests and analyses of covariance were used to examine within-group and between-group differences. Path analysis was used to evaluate mediational relationships between CRF and changes in CRF's interference with walking, PA, and QoL among survivors.

RESULTS

Compared with standard care controls, YOCAS participants reported significant improvements in CRF's interference with walking, PA, and QoL at postintervention (all effect size = -0.33; all P≤.05). Improvements in CRF resulting from yoga accounted for significant proportions of the improvements in walking (44%), PA (53%), and QoL (45%; all P≤.05).

CONCLUSIONS

A significant proportion (44%-53%) of the YOCAS effect on CRF's interference with walking, PA, and QoL was due to improvements in CRF among cancer survivors. Yoga should be introduced and included as a treatment option for survivors experiencing fatigue. By reducing fatigue, survivors further improve their walking, engagement in PA, and QoL.

The Impact of Cytoreductive Surgery and Hyperthermic Intraperitoneal Chemotherapy (CRS-HIPEC) versus Conventional Surgery on Patient-Reported Outcomes: A Comparative Cohort Study between the CAIRO6 Trial and the PROCORE Study

Purpose-To compare patient-reported outcomes (PROs) of patients undergoing cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) for colorectal peritoneal metastases to PROs of colorectal cancer (CRC) patients undergoing conventional surgery. Methods-Data were extracted from the CAIRO6 trial (CRS-HIPEC group) and the PROCORE study (conventional surgery group). Nine predefined PROs (derived from the EORTC QLQ-C30 questionnaire) were compared at baseline, in the early postoperative period and one year postoperatively, with correction for treatment with systemic therapy using linear mixed modeling. Results-In total, 331 patients were included: 71 in the CRS-HIPEC group and 260 in the conventional surgery group. All predefined PROs (fatigue, diarrhea, C30 summary score, Global Health Status, physical, role, emotional, cognitive, and social functioning) did not differ significantly between the groups at all three timepoints, and differential effects over time for all PROs did not differ significantly between the groups. Significant worsening of fatigue, C30 summary score, physical and role functioning (both groups), and cognitive and social functioning (conventional surgery group only) was present in the early postoperative period. All scores returned to baseline at one year postoperatively, except for physical and cognitive functioning in the conventional surgery group. Emotional functioning improved postoperatively in both groups compared to baseline. Conclusion-Despite a more extensive procedure with greater risk of morbidity, CRS-HIPEC in patients with colorectal peritoneal metastases did not have a greater negative impact on PROs than conventional surgery in patients with CRC. Further, systemic therapy did not affect these PROs. These findings may facilitate future patient counseling and shared decision making in clinical practice.

Longitudinal associations of plasma metabolites with persistent fatigue among colorectal cancer survivors up to 2 years after treatment

The underlying biological mechanisms causing persistent fatigue complaints after colorectal cancer treatment need further investigation. We investigated longitudinal associations of circulating concentrations of 138 metabolites with total fatigue and subdomains of fatigue between 6 weeks and 2 years after colorectal cancer treatment. Among stage I-III colorectal cancer survivors (n = 252), blood samples were obtained at 6 weeks, and 6, 12 and 24 months posttreatment. Total fatigue and fatigue subdomains were measured using a validated questionnaire. Tandem mass spectrometry was applied to measure metabolite concentrations (BIOCRATES AbsoluteIDQp180 kit). Confounder-adjusted longitudinal associations were analyzed using linear mixed models, with false discovery rate (FDR) correction. We assessed interindividual (between-participant differences) and intraindividual longitudinal associations (within-participant changes over time). In the overall longitudinal analysis, statistically significant associations were observed for 12, 32, 17 and three metabolites with total fatigue and the subscales "fatigue severity," "reduced motivation" and "reduced activity," respectively. Specifically, higher concentrations of several amino acids, lysophosphatidylcholines, diacylphosphatidylcholines, acyl-alkylphosphatidylcholines and sphingomyelins were associated with less fatigue, while higher concentrations of acylcarnitines were associated with more fatigue. For "fatigue severity," associations appeared mainly driven by intraindividual associations, while for "reduced motivation" stronger interindividual associations were found. We observed longitudinal associations of several metabolites with total fatigue and fatigue subscales, and that intraindividual changes in metabolites over time were associated with fatigue severity. These findings point toward inflammation and an impaired energy metabolism due to mitochondrial dysfunction as underlying mechanisms. Mechanistic studies are necessary to determine whether these metabolites could be targets for intervention.

Prevalence, Characteristics, and Correlates of Fatigue in Indian Breast Cancer Survivors: A Cross-Sectional Study

Navneet KaurBackground  Fatigue is one of the commonest sequelae of breast cancer treatment that adversely impacts quality of life (QOL) of breast cancer survivors (BCSs). However, very limited data are available about cancer-related fatigue in Indian patients. Hence, this study was planned with the objectives to study (1) prevalence of fatigue in short-, intermediate-, and long-term follow-up; (2) severity and characteristics of fatigue; (3) impact of fatigue on QOL; and (4) correlation of fatigue with other survivorship issues. Materials and Methods  The study was conducted on ( n  = 230) BCSs who had completed their primary treatment (surgery, radiotherapy, and chemotherapy) and were coming for follow-up. The prevalence of fatigue was noted from a screening tool, which comprised of 14 commonly reported survivorship issues. Assessment of fatigue was done by using survivorship fatigue assessment tool-1 score and QOL was assessed by functional assessment of cancer therapy-breast (FACT-B) questionnaires. To understand how fatigue evolved over time, survivors were divided into three groups according to the time elapsed since initial treatment: Group 1: <2 years ( n  = 105); Group 2: 2-5 years ( n  = 70); Group 3: >5 years ( n  = 55). Statistical Analysis  Data was analyzed by using simple descriptive statistics, one way analysis of variance followed by Tukey's test for comparison of quantitative data among the three groups, and Pearson correlation coefficients for association of fatigue with other survivorship issues. Results  Clinically significant fatigue (≥4) was noted in 38% of BCSs. However, high overall prevalence of fatigue (60%) was seen, which persisted in long-term survivors (51%) as well. Severity of fatigue was mostly mild (37.7%) to moderate (47.1%). Fatigue scores were significantly higher in short-term survivors ( 5.01 ± 2.06) than intermediate- (4.03 ± 1.42) and long-term BCSs (3.57 ± 1.37). The mean score on FACT-B was 90.07 ± 10.17 in survivors with fatigue and 104.73 ± 7.13 in those without fatigue ( p  = 0.000). Significant correlation of fatigue was seen with other survivorship issues like limb swelling, chronic pain, premature menopause, and its related symptoms and emotional distress. Conclusion  Fatigue is highly prevalent in BCSs. Survivorship care programs should include appropriate measures to evaluate and address fatigue.

The Role of the Quality of Relationship in Couples Facing Treatment for Breast Cancer: A Qualitative Italian Study

INTRODUCTION

Breast cancer is the leading cause of cancer death in women worldwide. Recently, the focus of research has shifted from psychiatric, psychological, and social consequences on the woman who gets sick from breast cancer to the impact on the couple. Indeed, the psychosocial perspective has developed the construct of the Quality of Relationship (QoR) that affects the quality of life of both members of the dyad.

OBJECTIVE

The aim of this study was to extend knowledge in this field by identifying and analyzing what dimensions of QoR may impact couples' psychosocial adjustment to breast cancer and related treatments.

PATIENTS AND METHODS

Semistructured interviews explored couples' experiences of breast cancer diagnosis and treatment. Transcripts were analyzed using inductive thematic analysis.

RESULTS

Twelve couples were interviewed. Results showed how the dimensions of psychosocial support, dyadic coping, communication, and intimacy are associated and define the construct of QoR, thus affecting the couples' adjustment to breast cancer diagnosis and to the disease pathway.

CONCLUSION

Assessment procedures of couple functioning since and after diagnosis could increase the appropriateness and benefits of integrating existing clinical practice in oncological settings.

Meta-Analysis of Pharmacological, Nutraceutical and Phytopharmaceutical Interventions for the Treatment of Cancer Related Fatigue

Purpose: In this study we aimed to estimate the effectiveness of pharmacological, nutraceutical, and phytopharmaceutical treatments on CRF. Methods: Ovid MEDLINE, Ovid Embase, Ovid Psych info, CINHAHL and Cochrane Library databases were searched up to 30 September 2021. Randomized controlled trials of pharmacological, nutraceutical and phytopharmaceutical interventions for treatment of CRF for at least one week duration and have used valid tool to assess severity of CRF as a primary or secondary outcome were considered. Results: 32 eligible studies (4896 patients) were reviewed. For the overall meta-analysis, the random effect models yielded the treatment effect (95% CI) of −0.29 (−0.48,−0.09), p < 0.001. The meta-analysis did not show significant reduction of CRF with treatment with ginseng (n = 6), guarana (n = 3), megestrol (n = 2), mistletoe (n = 3), psychostimulants (n = 14), SSRI/antidepressants (n = 2). Corticosteroids (n = 2) showed significant reduction in CRF with treatment effects of 0.94 (−1.21, −0.67), p <0.0001, respectively. Conclusions: In this study, overall meta-analysis of all studies demonstrates significant reduction of CRF using Pharmacological, Nutraceutical and Phytopharmaceutical interventions with a pooled standardized treatment effect of −0.29. Metanalysis of Corticosteroids studies showed significant reduction in CRF. Further studies are needed.

Serum metabolomics reveals the effects of accompanying treatment on fatigue in patients with multiple myeloma

PURPOSE

The renewal and iteration of chemotherapy drugs have resulted in more frequent long-term remissions for patients with multiple myeloma (MM). MM has transformed into a chronic illness for many patients, but the cancer-related fatigue (CRF) of many MM convalescent patients experience is frequently overlooked. We investigated whether the accompanying treatment of family members would affect MM patients' CRF and explore their serum metabolomics, so as to provide clinicians with new ideas for identifying and treating CRF of MM patients.

METHODS

This was a single-center study, and a total of 30 MM patients were included in the study. Patients were divided into two groups based on whether they have close family members accompanying them through the whole hospitalization treatment. These patients received regular chemotherapy by hematology specialists, and long-term follow-up was done by general practitioners. Patients' CRF assessment for several factors used the Chinese version of the Brief Fatigue Inventory (BFI-C). Face-to-face questionnaires were administered at a time jointly determined by the patient and the investigator. All questionnaires were conducted by a general practitioner. The LC-MS-based metabolomics analysis determined whether the patients' serum metabolites were related to their fatigue severity. A correlation analysis investigated the relationship between serum metabolites and clinical laboratory indicators.

RESULTS

The fatigue severity of MM patients whose family members participated in the treatment process (group A) was significantly lower than patients whose family members did not participate in the treatment process (group B). There was a statistically significant difference (fatigue severity composite score: t =  - 2.729, p = 0.011; fatigue interference composite score: t =  - 3.595, p = 0.001). There were no differences between the two groups of patients' gender, age, regarding clinical staging, tumor burden, blood routine, biochemical, or coagulation indexes. There were 11 metabolites, including guanidine acetic acid (GAA), 1-(Methylthio)-1-hexanethiol, isoeucyl-asparagine, L-agaritine, tryptophyl-tyrosine, and betaine, which significantly distinguished the two groups of MM patients. GAA had the strongest correlation with patient fatigue, and the difference was statistically significant (fatigue severity composite score: r = 0.505, p = 0.0044; fatigue interference composite score: r = 0.576, p = 0.0009). The results showed that GAA negatively correlated with albumin (r =  - 0.4151, p = 0.0226) and GGT (r =  - 0.3766, p = 0.0402). Meanwhile, GAA positively correlated with PT (r = 0.385, p = 0.0473), and the difference was statistically significant.

CONCLUSION

The study is the first to report that family presence throughout the whole hospitalization may alleviate CRF in MM patients. Moreover, the study evaluated serum metabolites linked to CRF in MM patients and found that CRF has a significant positive correlation with GAA. GAA may be a more sensitive biomarker than liver enzymes, PT, and serum albumin in predicting patient fatigue. While our sample may not represent all MM patients, it proposes a new entry point to help clinicians better identify and treat CRF in MM patients.

Fatigue, Emotional Distress, and Illness Uncertainty in Patients with Metastatic Cancer: Results from the Prospective NEOETIC_SEOM Study

A cancer diagnosis can have a substantial impact on a patient's mental health and quality of life. The aim of this study was to investigate the prevalence of fatigue, emotional distress, and uncertainty and examine the predictive value they have on the quality of life of advanced cancer patients. A prospective, multicenter study was conducted between February 2020 and May 2021 of individuals diagnosed with an advanced, unresectable neoplasm prior to initiating systemic antineoplastic treatment. Participants completed questionnaires to quantify fatigue, emotional distress, disease uncertainty, and quality of life. A linear regression analysis was performed to study the predictive QoL variables. The study population comprised 508 patients, 53.7% of whom were male and had a mean age of 54.9 years. The most common cancers were digestive (40.6%), bronchopulmonary (29.1%), and breast (8.5%); the most frequent histology was adenocarcinoma (63%); and most were stage IV (79.7%). More than half (55.7%) suffered fatigue, and 47.7% exhibited emotional distress; both were more prevalent among women. Fatigue, emotional distress, and disease uncertainty all correlate with diminished quality of life. Similarly, ECOG performance status and the demographic variables of age, sex, and comorbidities impacted quality of life. This patient sample displayed a high prevalence of fatigue and emotional distress, together with illness uncertainty, which are clearly linked to waning quality of life. To decrease the experience of fatigue and improve mental health treatment in cancer patients, interventions based on a biopsychosocial model must be intensified.

Effects of Exercise Programs on Psychoemotional and Quality-of-Life Factors in Adult Patients with Cancer and Hematopoietic Stem Cell Transplantation or Bone Marrow Transplantation: A Systematic Review

This review analyzed the effects of an exercise program on psychoemotional and quality-of-life (QoL) factors in adult patients with cancer and hematopoietic stem cell transplantation (HSCT) or bone marrow transplantation (BMT). Studies were identified from the PubMed and Web of Science databases (from inception to 24 August 2022), according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. The methodological quality of the included studies was assessed with the Physiotherapy Evidence Database (PEDro) scale, based in turn on the Delphi list. A total of 20 randomized controlled studies were included with 1219 participants. The main result of this systematic review is that exercise program interventions produce improvements on psychoemotional and QoL factors in adult patients with cancer and HSCT or BMT. Moreover, exercise programs may have a beneficial effect on health, maintaining or increasing the patient's QoL. Further, it has a positive effect on the prevention and control of transplant complications in combination with medical treatment.

Correlates of Cancer-Related Fatigue among Colorectal Cancer Patients Undergoing Postoperative Adjuvant Therapy Based on the Theory of Unpleasant Symptoms

BACKGROUND

Cancer-related fatigue (CRF) is a common and burdensome symptom in cancer patients that is influenced by multiple factors. Identifying factors associated with CRF may help in developing tailored interventions for fatigue management. This study aimed to examine the correlates of CRF among colorectal cancer patients undergoing postoperative adjuvant therapy based on the theory of unpleasant symptoms.

METHODS

A cross-sectional study was implemented, and finally, a sample of 363 participants from one tertiary general hospital and one tertiary cancer hospital was purposively recruited. Data were collected using the general information questionnaire, cancer fatigue scale, the distress disclosure index, Herth hope index, and perceived social support scale. Univariate analysis and multiple linear regression analysis were performed to determine the correlates of CRF.

RESULTS

The mean score of CRF among colorectal cancer patients was 21.61 (SD = 6.16, 95% CI 20.98-22.25), and the fatigue degree rating was "moderate". The multiple linear regression model revealed that 49.1% of the variance in CRF was explained by hope, sleep disorder, internal family support, self-disclosure, pain, and time since operation.

CONCLUSIONS

Our study identified several significant, modifiable factors (self-disclosure, hope, internal family support, pain, and sleep disorder) associated with CRF. Understanding these correlates and developing targeted psychosocial interventions may be associated with the improvement of CRF in patients with colorectal cancer.

Sleep-wake Disturbance following Allogeneic Hematopoietic Stem Cell Transplantation: Trajectory and Correlates.. [DOI: 10.21203/rs.3.rs-2055018/v1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0]

Adults undergoing allogeneic hematopoietic stem-cell transplant (HSCT) experience progressive physical and psychosocial distress in early stages post-HSCT, including sleep-wake disturbance (SWD), psychological distress, and fatigue. We conducted a longitudinal feasibility study to determine severity/trajectory of SWDs and investigated relationships among actigraphic sleep parameters, sleepiness, insomnia severity, fear of cancer recurrence (FCR), anxiety, depression, and fatigue at 100 (T1), 150 (T2), and 180 days (T3) post-HSCT. Eight adults enrolled. Median total sleep time (TST) at T1–T3 days was adequate (7.24, 7.17, and 7.09 hours), but sleep efficiency (SE) was suboptimal (78.9%, 78.5%, 83.67%). Median Epworth Sleepiness Scale (ESS) and Insomnia Severity Index (ISI) scores indicated minimal drowsiness and subclinical insomnia at T1–T3. Median FCR Inventory (FCRI) scores indicate diminishing FCR over time. Median scores across time for anxiety (48.05, 50.2, and 44.1) and depression (44.9, 41, and 41) suggest moderate–mild distress with slight fluctuations. Surprisingly, fatigue scores increased from T1–T3 (46, 50.9, and 52.1). Increases in ISI and FCRI scores were associated with modest increases in anxiety. Findings suggest the need to evaluate and address sleep, psychological distress, and fatigue in HSCT recipients. Larger studies to confirm prevalence of SWD and association with psychological factors are warranted.

Screening and Assessment of Cancer-Related Fatigue: A Clinical Practice Guideline for Health Care Providers

Cancer-related fatigue (CRF) is the most common side effect of cancer treatment. Regular surveillance is recommended, but few clinical practice guidelines transparently assess study bias, quality, and clinical utility in deriving recommendations of screening and assessment methods. The purpose of this clinical practice guideline (CPG) is to provide recommendations for the screening and assessment of CRF for health care professions treating individuals with cancer. Following best practices for development of a CPG using the Appraisal of Guidelines for Research and Evaluation (AGREE) Statement and Emergency Care Research Institute (ECRI) Guidelines Trust Scorecard, this CPG included a systematic search of the literature, quality assessment of included evidence, and stakeholder input from diverse health care fields to derive the final CPG. Ten screening and 15 assessment tools supported by 114 articles were reviewed. One screen (European Organisation for Research and Treatment of Cancer-Quality of Life Questionnaire-30 Core Questionnaire) and 3 assessments (Piper Fatigue Scale-Revised, Functional Assessment of Chronic Illness Therapy-Fatigue, and Patient Reported Outcome Measurement Information System [PROMIS] Fatigue-SF) received an A recommendation ("should be used in clinical practice"), and 1 screen and 5 assessments received a B recommendation ("may be used in clinical practice"). Health care providers have choice in determining appropriate screening and assessment tools to be used across the survivorship care continuum. The large number of tools available to screen for or assess CRF may result in a lack of comprehensive research evidence, leaving gaps in the body of evidence for measurement tools. More research into the responsiveness of these tools is needed in order to adopt their use as outcome measures.

IMPACT

Health care providers should screen for and assess CRF using one of the tools recommended by this CPG.

Serum 25-hydroxyvitamin D and cancer-related fatigue: associations and effects on depression, anxiety, functional capacity and health-related quality of Life in breast cancer survivors during adjuvant endocrine therapy

Background

The adjuvant treatment with Aromatase Inhibitor (AI) is considered standard of care for postmenopausal breast cancer (BC) women with hormone receptor-positive (HR +), however, it often causes adverse effects such as cancer-related fatigue (CRF). The high prevalence of vitamin D deficiency in postmenopausal women who start adjuvant AI supports the hypothesis that hypovitaminosis D would be one of the biological explanations for toxicity of AI. This study aimed to identify the relationship between 25-hydroxyvitamin D [25(OH)D] and CRF, and to analyze their associations and effects on depression, anxiety, functional disability, muscle/joint aches and HRQL.

Methods

This prospective study included 89 postmenopausal women diagnosed with HR + early BC in adjuvant endocrine therapy with AI. Anthropometric and body composition assessments were performed, as well as dietary assessments by application of 24-h dietary recall, at three time points, totaling 24 months of follow-up. The women completed the Cervantes Scale (CS), Hospital Anxiety and Depression Scale (HADS) and Health Assessment Questionnaire (HAQ). The CRF was determined from the Functional Assessment of Chronic Illness Therapy-fatigue (FACIT-F). The serum 25(OH)D was determined by electrochemiluminescence, with cut-off point above 75 nmol/L adopted as sufficiency. Generalized Linear Model (GLzM) and Generalized Mixed Model (GMM) analysis were used.

Results

At baseline, 36% (n = 32) of the women presented CRF and 39.3% (n = 35) had 25(OH)D below 75 nmol/L. None of the women reached the Estimated Average Requirements (EAR) of vitamin D. The causality between 25(OH)D and CRF was not significant. Longitudinally, lower levels of 25(OH)D had a negative effect on anxiety (p = 0.020), Menopause and Health (p = 0.033) and Vasomotor scores (p = 0.007). Also, the CRF had a negative effect on anxiety (p = 0.028); depression (p = 0.027); functional disability (p = 0.022); HRQL (p = 0.007); Menopause and Health (p = 0.042), Psychological (p = 0.008) and Couple Relations (p = 0.008) domains; and on Health (p = 0.019) and Aging (p = 0.036) subdomains. Vasomotor subdomain (β = -2.279, p = 0.045) and muscle/joint aches (β = -0.779, p = 0.013) were significant with CRF only at baseline.

Conclusions

This study found negative effect of body adiposity on CRF. Still, the clinical relevance of 25(OH)D and CRF is highlighted, especially that of CRF, considering the consistent impact on several adverse effects reported by BC survivors during adjuvant endocrine therapy.

Effects of Acceptance and Commitment Therapy on fatigue interference and health-related quality of life among patients with advanced lung cancer: A pilot randomized controlled trial

Objective

The present study aimed to examine the feasibility and preliminary effects of Acceptance and Commitment Therapy (ACT) on fatigue interference and health-related quality of life in patients with advanced lung cancer.

Methods

In a single-blinded, parallel-group randomized controlled trial, 40 patients with advanced lung cancer were randomized to either the intervention group, which received the four-session individual ACT in 4 weeks, or the control group, which received usual care. The outcomes were evaluated at baseline and one week postintervention.

Results

Intervention feasibility and acceptability were established with a high attendance rate of 88.75% and a high retention rate of 75%. Approximately 95% of the participants reported satisfaction with the intervention. Despite the insignificant effects on fatigue interference, statistically significant interactions effects of ACT for health-related quality of life (P ​= ​0.001), cancer-related fatigue (P ​< ​0.001), depressive symptoms (P ​< ​0.001), anxiety (P ​< ​0.001), and distress (P ​= ​0.003) were noted.

Conclusions

This pilot trial supports the feasibility and acceptability of conducting ACT for patients with advanced lung cancer. The findings show the potential positive effects of ACT on health-related quality of life. Future studies with full-scale samples are recommended to evaluate the long-term effects of ACT on fatigue interference.

Mechanisms of Neuromuscular Fatigability in People with Cancer-Related Fatigue

INTRODUCTION

Cancer-related fatigue (CRF) is a debilitating symptom that affects around one-third of people for months or years after cancer treatment. In a recent study, we found that people with posttreatment CRF have greater neuromuscular fatigability. The aim of this secondary analysis was to examine the etiology of neuromuscular fatigability in people with posttreatment CRF.

METHODS

Ninety-six people who had completed cancer treatment were dichotomized into two groups (fatigued and nonfatigued) based on a clinical cut point for fatigue. Alterations in neuromuscular function (maximal voluntary contraction peak force, voluntary activation, potentiated twitch force, and EMG) in the knee extensors were assessed across three common stages of an incremental cycling test. Power outputs during the fatigability test were expressed relative to gas exchange thresholds to assess relative exercise intensity.

RESULTS

The fatigued group had a more pronounced reduction in maximal voluntary contraction peak force and potentiated twitch force throughout the common stages of the incremental cycling test (main effect of group: P < 0.001, ηp2 = 0.18 and P = 0.029, ηp2 = 0.06, respectively). EMG was higher during cycling in the fatigued group (main effect of group: P = 0.022, ηp2 = 0.07). Although the relative intensity of cycling was higher in the fatigued group at the final common stage of cycling, this was not the case during the initial two stages, despite the greater impairments in neuromuscular function.

CONCLUSIONS

Our results suggest that the rapid impairments in neuromuscular fatigability in people with CRF were primarily due to disturbances at the level of the muscle rather than the central nervous system. This could affect the ability to tolerate daily physical activities.

Fatigue severity and avoidance among individuals with chronic disease: A meta-analysis

OBJECTIVE

Fatigue is a common, debilitating symptom experienced by individuals with chronic disease. Avoidance, or the act of evading unwanted experiences, is associated with fatigue across chronic disease samples. The current study sought to determine the strength of association between fatigue severity and avoidance in individuals with chronic disease.

METHODS

PubMed, PsycINFO, CINAHL, and ProQuest Dissertations and Theses databases were searched. Eligible studies measured fatigue and avoidance in chronic disease samples. Sixty-six studies were included. Data analyses were conducted in Rstudio. A random effects model was employed, and a weighted mean effect size was computed for fatigue severity and avoidance. Mixed-effects meta-regression analyses were conducted to examine moderating variables, including patient, clinical, and measurement characteristics. Publication bias was examined using funnel plot, trim-and-fill, and p-curve.

RESULTS

The meta-analysis comprised of 71 unique patient samples from 66 studies. The total number of included participants was 13,024. A small, positive association was found between fatigue severity and avoidance, r(71) = 0.22, p < .001, 95% CI [0.18-0.27], SE = 0.02. There was also significant heterogeneity, Q(70) = 349.96, p < .001. Moderator analyses examining age, sex, illness duration, avoidance type, and disease sample were all non-significant. Regarding publication bias, trim-and-fill resulted in a modified weighted mean effect size (r(83) = 0.18, p < .001) and a p-curve analysis supported the evidential value of the current analysis.

CONCLUSION

Findings support that among individuals with chronic disease, fatigue severity and avoidance are positively associated, which has implications for behavioral interventions in this population.

The effects of mindfulness-based interventions on symptoms of depression, anxiety, and cancer-related fatigue in oncology patients: A systematic review and meta-analysis

Objective

Mindfulness-based interventions (MBIs) are increasingly being integrated into oncological treatment to mitigate psychological distress and promote emotional and physical well-being. This review aims to provide the most recent evaluation of Mindfulness-Based Stress Reduction (MBSR), Mindfulness-Based Cognitive Therapy (MBCT), and Mindfulness-Based Cancer Recovery (MBCR) treatments, in reducing symptoms of depression, anxiety and CRF in oncology populations.

Methods

A search using the following search terms was conducted: (mindful* OR mindfulness* OR mindfulness-based* OR MBI* OR MBCT OR MBSR OR MBCR) AND (Oncol* OR cancer OR neoplasm OR lymphoma OR carcinoma OR sarcoma) to obtain relevant publications from five databases: PsycINFO, PubMed, Embase, and MEDLINE by EC, and ProQuest Dissertations & Theses Global from January 2000 to February 2022. 36 independent studies (n = 1677) were evaluated for their overall effect sizes (using random-effects models), subgroup analyses, and quality appraisals. Evaluations were performed separately for non-randomized (K = 20, n = 784) and randomized controlled trials (K = 16, n = 893).

Results

The results showed that MBIs have significant medium effects in reducing symptoms of depression (Hedges’ g = 0.43), anxiety (Hedges’ g = 0.55) and CRF (Hedges’ g = 0.43), which were maintained at least three months post-intervention. MBIs were also superior in reducing symptoms of anxiety (Hedges’ g = 0.56), depression (Hedges’ g = 0.43), and CRF (Hedges’ g = 0.42) in oncology samples relative to control groups. The superiority of MBIs to control groups was also maintained at least three months post-intervention for anxiety and CRF symptoms, but not for depressive symptoms. The risk of bias of the included studies were low to moderate.

Conclusions

This review found that MBIs reduced symptoms of depression, anxiety and CRF in oncology populations.
