Cancer-Related Fatigue: Causes and Current Treatment Options

Physical activity and exercise health benefits: cancer prevention, interception, and survival

Physical activity (PA) has an established role in the promotion of health and fitness and the prevention of disease. Expected overall benefits include reduction of all-cause morbidity and death, weight control, improved quality of life, improved bone health and decreased falls of elderly subjects, , deeper cognition, and reduced risk of depression, anxiety, and sleeplessness. Currently, PA is a mainstay in the management of cardiovascular diseases, metabolic syndrome, diabetes, and bone health. Recently, the perception of its role in primary and secondary prevention, interception, and treatment of cancer, however, is also gaining importance. Regular walking, the simplest type of PA, is associated with reduced all-cause and cardiovascular disease mortality, and a role in cancer prevention is of increasing interest. Furthermore, PA improves the quality of life of cancer patients, attenuating side effects of chemotherapy, decreasing sarcopenia, increasing fitness, and inhibiting the recurrence and progression of some cancer types. It promotes emotional and psychological benefits in patients, inducing positive changes. While mechanisms, effective levels and useful amount of PA practice are well established in cardiology, they are yet to be fully determined in oncology. Nevertheless, PA is recommended to reduce cancer risk in the general population, and it has been introduced in programs for the prevention of second cancers. In perspective, it will help as integrative therapy in cancer patients and for cancer survivors. The number of beneficial effects in the cancer continuum is highlighted in this review.

Health-related quality of life among adult patients with cancer in Uganda - a cross-sectional study

OBJECTIVES

The study aimed to investigate the prevalence and factors associated with poor health-related quality of life in adults with cancer in Uganda.

METHODS

This cross-sectional study surveyed 385 adult patients (95% response rate) with various cancers at a specialised oncology facility in Uganda. Health-related quality of life was measured using the EORTC QLQ-C30 in the Luganda and English languages. Predetermined validated clinical thresholds were applied to the instrument in order to identify patients with poor health-related quality of life, that is, functional impairments or symptoms warranting concern. Multivariable logistic regression was used to identify factors associated with poor health-related quality of life in six subscales: Physical Function, Role Function, Emotional Function, Social Function, Pain and Fatigue.

RESULTS

The mean age of the patients was 48 years. The majority self-reported poor functioning ranging between 61% (Emotional Function) to 79% (Physical Function) and symptoms (Fatigue 63%, Pain 80%) at clinically concerning levels. These patients were more likely to be older, without formal education and not currently working. Being an inpatient at the facility and being diagnosed with cervical cancer or leukaemia was a predictor of poor health-related quality of life.

CONCLUSION

Improvement of cancer care in East Africa requires a comprehensive and integrated approach that addresses various challenges specific to the region. Such strategies include investment in healthcare infrastructure, for example, clinical guidelines to improve pain management, and patient education and support services.

Identification of the Core Nutrition Impact Symptoms Cluster in Patients with Lung Cancer During Chemotherapy: A Symptom Network Analysis

OBJECTIVES

Lung cancer patients undergoing chemotherapy are present in multiple Nutrition Impact Symptoms (NIS). There have been no studies utilizing symptom networks to identify core NIS in lung cancer patients undergoing chemotherapy, it is necessary to identify core symptoms for effective and precise symptom management. We aimed to construct a symptom network of NIS in lung cancer patients receiving chemotherapy, and explore the core Nutrition Impact Symptoms cluster.

METHODS

A cross-sectional survey was conducted among 315 patients with lung cancer. The Patient-Generated Subjective Global Assessment-Short Form was used to assess the prevalence and severity of NIS. We constructed a symptom network and identified centrality indexes using R packages.

RESULTS

Fatigue emerged as the most prevalent and severe symptom, affecting 87% of participants, with an intensity of 3.0 ± 1.3. The network density was measured at 0.5. Strength centrality showed a stability coefficient of 0.7, with fatigue (Rs = 0.73), lack of appetite (Rs = 1.02), and nausea (Rs = 0.70) ranking as the top three symptoms. For betweenness centrality, the stability coefficient was 0.3, highlighting fatigue (Rb = 12), lack of appetite (Rb = 34), and emotional change (Rb = 18) as the primary symptoms.

CONCLUSIONS

This study identified a core symptom cluster consisting of fatigue, lack of appetite, and emotional change. These findings provide valuable insights for developing targeted symptom management strategies and interventions for this patient population in the future.

IMPLICATIONS FOR NURSING PRACTICE

Nurses need to comprehensively consider the interaction of multidimensional symptoms to provide lung chemotherapy cancer with targeted symptom management strategies and intervention guidance to reduce the burden of symptoms and improve quality of life.

Identification of diagnostic biomarkers in prostate cancer-related fatigue by construction of predictive models and experimental validation

BACKGROUND

Cancer-related fatigue (CRF) is a prominent cancer-related complication occurring in Prostate cancer (PCa) patients, profoundly affecting prognosis. The lack of diagnostic criteria and biomarkers hampers the management of CRF.

METHODS

The CRF-related data and PCa single-cell data were retrieved from the GEO database and clinical data was downloaded from the TCGA database. The univariate logistic/Cox regression analysis were used to construct the prediction models. The predictive value of models was analyzed using the ROC curve and Kaplan-Meier survival. The hub genes were screened by an intersection analysis of DEGs. The mice model of PCa and PCa-related fatigue were established, and fatigue-like behaviors of mice were detected. The expression of selected hub genes was validated by RT-PCR and IHC analysis.

RESULTS

The diagnosis and risk models showed great predictive value both in the training and validation dataset. Five genes (Baiap2l2, Cacng4, Sytl2, Sec31b and Ms4a1) that enriched the CXCL signaling were identified as hub genes. Among all hub genes, the MS4A1 expression is the most significant in PCa-related fatigue mice.

CONCLUSIONS

We identified MS4A1 as a promising biomarker for the diagnosis of PCa-related fatigue. Our findings would lay a foundation for revealing the pathogenesis and developing therapies for PCa-related fatigue.

Fatigue Syndrome in Patients with Bone and Soft Tissue Sarcomas: An Observational Study

OBJECTIVES

The aim of the present study is to describe the course of fatigue syndrome in patients with musculoskeletal tumors starting from chemotherapy and to compare it with that of other cancer populations. The second objective is to identify the risk factors for a higher level of fatigue.

METHODS

A prospective prognostic observational cohort study was carried out. All patients diagnosed with musculoskeletal tumors who started chemotherapy treatment over 12 years of age were identified and enrolled consecutively from July 2019 to April 2021 in the osteo-oncology department. Patients' fatigue was measured using the Brief Fatigue Inventory at four different time points: at the beginning of treatment and then subsequently at 6, 12 and 24 months from the time of enrollment.

RESULTS

The mean fatigue value was 3.3 (SD = 2.4) at the start of antiblastic treatment, which progressively decreased over time until it reached a mean score of 2.1 (SD = 1.5). At 24 months; 17% of patients had moderate/severe fatigue. Presence of metastases at the onset of the disease, location of the tumor in the upper limb, a shorter oncological treatment-free gap and surgical treatment were independent predictive factors of BFI score.

CONCLUSION

In patients with musculoskeletal tumors, fatigue is a complication of the disease itself and does not occur only after chemotherapy treatment. In the first two years of treatment, there is a decreasing trend in fatigue syndrome, which remains a significant complication to be monitored over time and to be considered in patient management. Prevention pathways should be implemented.

IMPLICATIONS FOR NURSING PRACTICE

During chemotherapy treatment of patients with bone and soft tissue sarcomas, a fatigue prevention plan should be implemented. Patients with tumor localisation in the upper limb, metastasis at onset and surgical treatment have a higher risk of developing a higher fatigue score.

Supporting cancer-related fatigue self-management: A conversation analytic study of nurse counsellor and cancer survivor consultations

PURPOSE

Cancer-related fatigue (CRF) is a prevalent and distressing symptom experienced by people affected by cancer. A breakdown of the clinician-patient partnership and suboptimal clinician communication has been identified as a significant barrier to implementing into clinical practice effective self-management strategies for CRF. This study examined the use and impact of communication practices employed by trained cancer nurse counsellors when providing CRF self-management support to cancer survivors.

METHODS

Interactions from 41 telehealth consultations between three nurse counsellors and 23 cancer survivors in a CRF self-management support clinic in Queensland, Australia were recorded and analysed using conversation analysis methods.

RESULTS

Analysis found that in instances where nurses established the agenda of a consultation from the outset of a session (e.g., focusing on fatigue self-management support), cancer survivors displayed clearer understandings of their self-management role, the tasks, and goals of a session; and displayed less difficulty engaging in supportive care discussions. Furthermore, clinicians used formulation practices, such as summarising dialogue, to sustain focus on fatigue during consultations, and to close discussion matters not ostensibly pertinent to fatigue self-management planning supporting the goals of the CRF SMS clinic consultations.

CONCLUSION

For supportive care sessions targeting fatigue management, clinicians should ideally focus discussion on CRF support early, by clearly introducing the agenda at the outset of the consultation while also asking for client agreement. Periodically summarising patient's talk allows clinicians to maintain a focus on matters relevant for self-management fatigue planning and provide support within the typically constrained timeframes allocated for addressing CRF.

Safety Analysis of Co-Administration of Radiation Therapy with Enfortumab Vedotin Based Regimens in Metastatic Urothelial Carcinoma

INTRODUCTION/BACKGROUND

Enfortumab vedotin (EV) and pembrolizumab (P) is the standard of care for patients with locally advanced or metastatic urothelial carcinoma (la/mUC). Because radiation (RT) is frequently used for symptom palliation, we examined the safety of co-administering EV with RT.

MATERIALS AND METHODS

This single institution retrospective study selected patients with la/mUC, who received at least 1 dose of EV and initiated RT to any site within 30 days of each other. Patient characteristics, number of EV cycles received, the location of irradiated sites, RT dose/delivery approach, severity/type of radiation treatment-related adverse events (TRAEs), and symptom response after RT were recorded. The primary aim of this study was to examine radiation TRAEs, with severity graded using the CTCAE version 5.0 classification.

RESULTS

Nine patients with 15 irradiated metastasis met eligibility criteria. The median radiation dose and cycles of EV were 30 Gy and 5 cycles respectively. Patients only experienced acute grade 1 or 2 TRAEs including fatigue, nausea, and dermatitis without desquamation. Chronic treatment-related toxicity was noted in 2 patients, which were grade 1 neck pain and 2 fatigue. All patients demonstrated some degree of symptom relief and four experienced complete resolution of their cancer-related symptoms at the irradiated site. One patient with limited disease burden completed stereotactic body radiation therapy and remains disease free 6 months after discontinuing all treatment.

CONCLUSION

This study demonstrates that co-administration of RT with EV-based regimens could be safe and effective for symptom palliation. Larger series examining this treatment combination are needed.

Factors influencing cancer-related fatigue in patients with esophageal cancer undergoing radiotherapy: pathway analysis

BACKGROUND

Cancer-related fatigue symptoms persist throughout the radiotherapy period in patients with esophageal cancer and show a continuous worsening trend, which seriously affects the quality of survival of patients. Therefore, monitoring patients' fatigue status promptly, recognizing highly fatigued patients, and providing physical and psychological support are essential for improving their quality of life. As a positive psychological trait, self-efficacy can influence the level of fatigue in patients undergoing radiotherapy for esophageal cancer. However, the pathways by which self-efficacy affects cancer-related fatigue remain unclear.

OBJECTIVE

The aim of this study is to investigate the factors influencing cancer-related fatigue in patients undergoing radiation therapy for esophageal cancer and to investigate the role of social support as a mediator between self-efficacy and cancer-related fatigue using the theory of unpleasant symptoms.

METHODS

The study used a descriptive survey approach, and data were collected at a tertiary hospital in Nanjing between October 2022 and May 2023. A total of 225 patients with esophageal cancer undergoing radiotherapy completed the Demographic Characteristics Scale, Cancer-Related Fatigue Scale, Self-Efficacy Scale, and Social Support Rating Scale. The data were statistically analyzed using SPSS version 26.0 (IBM, CHINA) and SPSS PROCESS 3.3 plug-in.

RESULTS

The cancer-related fatigue score of Chinese patients undergoing radiotherapy for esophageal cancer was 27.27 ± 7.26, which shows a high level of fatigue. Social support partially mediates the relationship between self-efficacy and cancer-related fatigue.

CONCLUSION

The findings may help medical personnel identify factors that influence cancer-related fatigue in patients undergoing radiotherapy for esophageal cancer and develop reasonable management strategies.

Symptoms and negative emotions in patients with advanced thyroid cancer: a prospective cross-sectional study

BACKGROUND

There is no relevant research on the symptoms and emotions of patients with advanced thyroid cancer in mainland China.

AIM

To investigate the symptoms and negative emotions of patients with advanced thyroid cancer and to analyze the correlation between the two preliminarily.

METHODS

Using a convenience sampling method, 180 patients who visited a multidisciplinary outpatient service for advanced thyroid cancer at West China Hospital of Sichuan University from January 2023 to December 2023 were selected as the research subjects. A cross-sectional survey was conducted using the M.D. Anderson Symptom Inventory-Thyroid Cancer module (MDASI-THY) and Hospital Anxiety and Depression Scale (HADS). The correlation between symptom severity and negative emotions was determined by Spearman correlation analysis.

RESULTS

Disturbed sleep was the symptom with the highest incidence (74.4%) and the greatest severity (3.0 points), while mood distress was the symptom with the highest incidence (63.3%) and the greatest severity (2.0 points). 71 patients (39.4%) had anxiety, and 62 patients (34.4%) had depression. All symptoms and symptom interference were positively correlated with anxiety and depression (P < 0.05).

CONCLUSION

Patients with advanced thyroid cancer have multiple symptoms that seriously affect their daily lives and emotions. Medical staff should conduct targeted observation and preventive treatment to reduce the burden of symptoms and improve the negative emotions of patients.

Physicians' perspectives on cancer-related fatigue management and their suggestions for improvements in medical training: a cross-sectional survey study in Germany

PURPOSE

Contrary to guidelines, many cancer patients are not screened for cancer-related fatigue (CRF) and do not receive information or adequate treatment. As physicians play a key role in cancer therapy, their knowledge of this common sequela and perspectives on its management are of major interest.

METHODS

For an online survey, physicians working in oncology in Germany were systematically drawn from registers and invited by using institutional newsletters or colleagues. Descriptive analyses, logistic regression analysis of physicians' knowledge, and Mann‒Whitney U tests were performed.

RESULTS

Two-thirds of the 148 surveyed physicians felt (rather) well informed about CRF and capable of counseling patients. Only 32% of the sample were aware of CRF-specific guidelines. Despite of this, participants rated the scientific evidence for recommending physical activity, exercise programs, and psychotherapeutic interventions in accordance with guidelines as being mostly (very) strong. However, despite 82.4% of the physicians being (rather) aware of its evidence, only 56.1% often to almost always recommended psychotherapeutic interventions. CRF was rarely covered in medical studies and medical specialist training. The completion of advanced training for palliative care increased the likelihood of knowing guidelines (OR = 2.6, 95% CI [1.1-6.0], p < 0.05). Suggestions for improving training included the mandatory coverage of CRF in medical training or its consideration in interprofessional supportive care workshops.

CONCLUSION

Although awareness and recommendation rates were adequate for some interventions in CRF treatment (such as physical activity), there were lower recommendation rates for others, including psychotherapy. Studies are required assessing for the reasons of this knowledge-to-practice gap. Moreover, training is needed among physicians in order to enhance knowledge of CRF guidelines.

Effects of Baduanjin exercise on cancer-related fatigue in patients with prostate cancer treated with androgen deprivation therapy in Shanghai, China: a study protocol for a randomised controlled trial

INTRODUCTION

Cancer-related fatigue (CRF) is one of the most common and painful symptoms in patients with prostate cancer (PCa). Moreover, PCa patients who receive the androgen deprivation therapy (ADT) are more likely to develop CRF. Baduanjin exercise has been shown to improve CRF in some cancers. However, such effects have not been verified in patients with PCa treated with the ADT. So, this study was designed as a randomised controlled trial (RCT) to explore the effects of Baduanjin exercise on CRF in PCa patients treated with the ADT.

METHODS AND ANALYSIS

This study will be a single-centre, assessor and statistician blinded, RCT consisting of a 12 week intervention and 12 week follow-up. Patients with PCa who meet the inclusion criteria will be recruited from Shanghai Hudong Hospital. Participants will be randomly assigned to Baduanjin exercise group (n=42) and the control group (n=42), performing 12 weeks of Baduanjin exercise or reeiving the standard care. The primary outcome will be the clinical effect of Baduanjin exercise on CRF in PCa patients, which will be measured using the Piper Fatigue Self-Assessment (PFS) scale, a multidimensional measure of CRF using three different dimensions: somatic, emotional and cognitive. The secondary outcome will be the clinical effect of the Baduanjin exercise on the patient's level of fatigue, sleep, depression and life quality at the time, which will be assessed by the Brief Fatigue Inventory (BFI), the Pittsburgh Sleep Quality Index (PSQI), the Beck Depression Inventory (BDI) and the Functional Assessment of Cancer Therapy-Prostate (FACT-P).

ETHICS AND DISSEMINATION

This study has been approved by Shanghai Hudong Hospital Ethics Committee, Shanghai province (2022 SHHDKY08). The trial results will be submitted to conferences and peer-reviewed journals.

Natural supplementation to effectively treat cancer-induced fatigue: evidence of a meta-analysis on the use of guaraná

BACKGROUND

Cancer-related fatigue is a pervasive symptom, affecting up to 90% of cancer patients throughout their illness, and can persist well after treatment has ended. Despite its prevalence, no definitive evidence-based treatment exists, leading to an abundance of proposed alternatives, including natural supplements. To further explore the potential effects of guaraná on cancer-related fatigue, a systematic review with meta-analysis was conducted and registered on the International Prospective Register of Systematic Reviews (CRD42023484144).

METHODS

A thorough search of PubMed/MEDLINE and Cochrane Library was conducted using MeSH terms and related keywords for cancer-related fatigue and guaraná. Eligible studies were selected according to predetermined criteria and assessed for quality in accordance with the Cochrane Handbook for Systematic Reviews of Interventions. Data extraction was independently performed by two reviewers, with any discrepancies resolved by a third researcher.

RESULTS

In total, 4 full articles and 1 abstract, encompassing a total of 229 patients from 2009 to 2023, were included in the meta-analysis. Despite high heterogeneity between studies (I2=78%, ꭓ2=18.51, df=4, p=0.0010), the analysis revealed a significant benefit of using guaraná to alleviate cancer-related fatigue, with a standard mean difference of -0.77 (95%CI -1.34, -0.21) and a test for the overall effect of Z=2.68 (p=0.007).

CONCLUSION

This meta-analysis provides support for the use of guaraná in the treatment of cancer-related fatigue. However, further investigation through larger prospective randomized controlled trials is necessary to validate these findings.

Systematic review of Buzhong Yiqi method in alleviating cancer-related fatigue: a meta-analysis and exploratory network pharmacology approach

Objectives

Cancer-related fatigue (CRF) is a prevalent and distressing symptom experienced by many cancer patients, necessitating effective treatments. This study utilizes meta-analysis and network pharmacology to comprehensively assess the efficacy of the Buzhong Yiqi prescription in alleviating cancer-related fatigue and to preliminarily explore the mechanism of its core drugs.

Methods

We included randomized controlled trials (RCTs) in cancer patients. The inclusion criteria encompassed a diagnosis of cancer-related fatigue, without limitation on cancer type, the experimental group receiving Buzhong Yiqi prescription, the control group receiving conventional treatment, patients awaiting treatment, and articles published in either English or Chinese. We conducted a search through 29 February 2024, across PubMed, Cochrane Database of Systematic Reviews, Cochrane Controlled Clinical Trials (CENTRAL), China Biomedical Literature Service (CBM), China National Knowledge Infrastructure (CNKI), WANFANG Database, and Weipu Database (VIP). Journal articles that met the inclusion criteria were selected for inclusion. Two independent investigators evaluated the quality of the included studies. A meta-analysis was performed utilizing the Stata 12.0 software package, where estimates of cancer-related fatigue were aggregated through the application of a random-effects model. We employed the Cochrane Risk of Bias Tool to evaluate potential biases in RCTs. The primary outcome measures utilized to assess the efficacy and safety of CRF treatment comprised the Revised Piper Fatigue Scale (PFS-R) and the Quality of Life Questionnaire Core 30 (EORTC QLQ-C30). The secondary outcomes encompassed the KPS score, the effective rate, the TCM syndrome score, and an evaluation of adverse reactions. The Traditional Chinese Medicine Systems Pharmacology (TCMSP) was utilized to identify the active ingredients and targets of BZD. Additionally, the Drug bank, Therapeutic Target Database (TTD), DiaGeNET, and GeneCards databases were utilized to retrieve relevant targets for CRC. The Venn diagram was employed to identify overlapping targets. Cytoscape software was utilized to construct a network of "herb-ingredient-target" and identify core targets. GO and KEGG pathway enrichment analyses were performed using R language software.

Results

In comparison to the control group, patients with CRF who received BZYQ prescription exhibited marked improvements in KPS score, QLQ-C30 quality of life score, and effective rate. Conversely, PFS, TCM syndrome score, and adverse reaction assessments significantly decreased. The primary active ingredients in its core drugs may exert a positive therapeutic effect on CRF by targeting molecules such as AKT1, IL6, IL1B, PTGS2, CASP3, ESR1, and BCL2, as well as through signaling pathways including TNF, IL17, TLR, NF-κB, and C-type lectin receptor.

Conclusion

BZYQ demonstrates significant efficacy in treating CRF with minimal adverse reactions. It can serve as a fundamental treatment for CRF in clinical practice, and the medication can be tailored to individual patients for personalized therapy. The potential pharmacological mechanism of BZYQ in treating CRF, as predicted by network pharmacology, offers a molecular foundation for clinical CRF treatment.

Neural Circuitries between the Brain and Peripheral Solid Tumors

The recent discovery of the pivotal role of the central nervous system in controlling tumor initiation and progression has opened a new field of research. Increasing evidence suggests a bidirectional interaction between the brain and tumors. The brain influences the biological behavior of tumor cells through complex neural networks involving the peripheral nervous system, the endocrine system, and the immune system, whereas tumors can establish local autonomic and sensory neural networks to transmit signals into the central nervous system, thereby affecting brain activity. This review aims to summarize the latest research in brain-tumor cross-talk, exploring neural circuitries between the brain and various peripheral solid tumors, analyzing the roles in tumor development and the related molecular mediators and pathologic mechanisms, and highlighting the critical impact on the understanding of cancer biology. Enhanced understanding of reciprocal communication between the brain and tumors will establish a solid theoretical basis for further research and could open avenues for repurposing psychiatric interventions in cancer treatment.

[Rehabilitative strategies in cancer-related fatigue]

Cancer-related fatigue (CRF) during and after tumor therapy influences all aspects of life and lowers performance and quality of life. Regular CRF screening and diagnostic evaluation are important factors in the care of patients. This article presents strategies for recognizing and treating CRF. Multiprofessional and personalized therapies can improve CRF. Outpatient and inpatient rehabilitative strategies should be implemented after completion of tumor therapy.

Health-related quality of life in older hematological cancer survivors (70+) compared to older general population-A German cancer-register-based cross-sectional comparative study

OBJECTIVES

The extent of health-related quality of life (HRQOL) impairments in older hematological cancer survivors (HCS) has not been sufficiently studied. We therefore examined HRQOL in older HCS compared to a community sample (CS) and investigated sociodemographic, disease- and treatment-specific, geriatric, and psychosocial factors associated with reduced HRQOL.

MATERIALS AND METHODS

In this cancer-register-based cross-sectional comparative study 200 HCS, aged ≥70 years, and 252 persons of an age- and gender-matched CS completed validated questionnaires including the EORTC QLQ-C30 and EORTC QLQ-ELD14.

RESULTS

Older HCS reported a reduced HRQOL in the dimensions of global QOL, physical, role, and social functioning (small clinical significance) and higher symptom burden of fatigue, nausea and vomiting, appetite loss, and poorer mobility compared to the CS (fatigue and mobility with medium, the others with small clinical significance). Perceived disease burden of comorbidities, functional disabilities, psychological distress, and depression showed statistical significance for reduced HRQOL in older HCS in multiple linear regression analysis (R2 = .602, p < .001).

DISCUSSION

The screening and treatment of functional limitations and individual symptoms and the integration of a geriatric assessment into oncological practice can help to identify supportive care needs, to implement individualized, patient-centered cancer survivorship care programs and to improve older HCS's HRQOL.

Preclinical Multi-Omic Assessment of Pioglitazone in Skeletal Muscles of Mice Implanted with Human HER2/neu Overexpressing Breast Cancer Xenografts

Background/Objectives: Breast cancer (BC) is the second most commonly diagnosed cancer worldwide and is accompanied by fatigue during both active disease and remission in the majority of cases. Our lab has measured fatigue in isolated muscles from treatment-naive BC patient-derived orthotopic xenograft (BC-PDOX) mice. Here, we conducted a preclinical trial of pioglitazone in BC-PDOX mice to determine its efficacy in ameliorating BC-induced muscle fatigue, as well as its effects on transcriptomic, metabolomic, and lipidomic profiles in skeletal muscle. Methods: The pioglitazone and vehicle groups were treated orally for 4 weeks upon reaching a tumor volume of 600 mm3. Whole-animal indirect calorimetry was used to evaluate systemic metabolic states. The transcriptome was profiled using short-read bulk RNA sequencing (RNA-seq). Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to profile the metabolome and lipidome. Fast and slow skeletal muscle function were evaluated using isolated ex vivo testing. Results: Pioglitazone was associated with a 16.634% lower average O2 consumption (mL∙h-1, p = 0.035), 16.309% lower average CO2 production (mL∙h-1, p = 0.022), and 16.4% lower cumulative energy expenditure (EE) (kcal∙h-1, p = 0.035), with no changes in substrate utilization. RNA-seq supported the downstream effects of pioglitazone on target genes and displayed considerable upregulation of mitochondrial bioenergetic pathways. K-means cluster 5 showed enrichment of the PPAR signaling pathway (adj. p < 0.05, Log2FC = 2.58). Skeletal muscle metabolomic and lipidomic profiles exhibited dysregulation in response to BC, which was partially restored in pioglitazone-treated mice compared to vehicle-treated BC-PDOX mice. In particular, the overall abundance of total ceramide levels was significantly lower in the PioTx group (-46.327%, p = 0.048). Despite molecular support for pioglitazone's efficacy, isolated muscle function was not affected by pioglitazone treatment. No significant difference in the area under the fatigue curve (AUC) was found between the pioglitazone and vehicle groups (p = 0.596). Conclusions: BC induces multi-omic dysregulation in skeletal muscle, which pioglitazone partially ameliorates. Future research should focus on profiling systemic metabolic dysfunction, identifying molecular biomarkers of fatigue, and testing alternative pioglitazone treatment regimens.

Biological network comparison identifies a novel synergistic mechanism of Ginseng Radix-Astragali Radix herb pair in cancer-related fatigue

ETHNOPHARMACOLOGICAL RELEVANCE

Ginseng Radix and Astragali Radix are commonly combined to tonify Qi and alleviate fatigue. Previous studies have employed biological networks to investigate the mechanisms of herb pairs in treating different diseases. However, these studies have only elucidated a single network for each herb pair, without emphasizing the superiority of the herb combination over individual herbs.

AIM OF THE STUDY

This study proposes an approach of comparing biological networks to highlight the synergistic effect of the pair in treating cancer-related fatigue (CRF).

METHODS

The compounds and targets of Ginseng Radix, Astragali Radix, and CRF diseases were collected and predicted using different databases. Subsequently, the overlapping targets between herbs and disease were imported into the STRING and DAVID tools to build protein-protein interaction (PPI) networks and analyze enriched KEGG pathways. The biological networks of Ginseng Radix and Astragali Radix were compared separately or together using the DyNet application. Molecular docking was used to verify the predicted results. Further, in vitro experiments were conducted to validate the synergistic pathways identified in in silico studies.

RESULTS

In the PPI network comparison, the combination created 89 new interactions and an increased average degree (11.260) when compared to single herbs (10.296 and 9.394). The new interactions concentrated on HRAS, STAT3, JUN, and IL6. The topological analysis identified 20 core targets of the combination, including three Ginseng Radix-specific targets, three Astragali Radix-specific targets, and 14 shared targets. In KEGG enrichment analysis, the combination regulated additional signaling pathways (152) more than Ginseng Radix (146) and Astragali Radix (134) alone. The targets of the herb pair synergistically regulated cancer pathways, specifically hypoxia-inducible factor 1 (HIF-1) signaling pathway. In vitro experiments including enzyme-linked immunosorbent assay and Western blot demonstrated that two herbs combination could up-regulate HIF-1α signaling pathway at different combined concentrations compared to either single herb alone.

CONCLUSION

The herb pair increased protein interactions and adjusted metabolic pathways more than single herbs. This study provides insights into the combination of Ginseng Radix and Astragali Radix in clinical practice.

Symptom clusters of patients with advanced thyroid cancer: a cross-sectional study

PURPOSE

To investigate and analyze the symptom clusters of patients with advanced thyroid cancer and provide a basis for developing targeted symptom management measures.

METHODS

Patients who visited a multidisciplinary outpatient service for advanced thyroid cancer at a tertiary A hospital in Sichuan Province from April 2022 to April 2023 were selected using convenience sampling. A cross-sectional survey was conducted using the M.D. Anderson Symptom Inventory-Thyroid Cancer module (MDASI-THY). Symptom clusters were extracted by exploratory factor analysis.

RESULTS

Disturbed sleep had the highest incidence (75.7%) and severity (3.0 points), while mood distress had the highest incidence (63.5%) and severity (2.0 points) of symptom interference. Three symptom clusters were identified: mood-fatigue-sleep, digestive tract-sensation, and thyroid cancer-specific symptom clusters.

CONCLUSION

Patients with advanced thyroid cancer have multiple symptom clusters that seriously affect their daily lives. Health care professionals should conduct targeted observation and preventive treatment to reduce the burden of symptoms on patients.

Underlying mechanisms and management strategies for regorafenib-induced toxicity in hepatocellular carcinoma

INTRODUCTION

Hepatocellular carcinoma (HCC) accounts for 85% of liver cancer cases and is the third leading cause of cancer death. Regorafenib is a multi-target inhibitor that dramatically prolongs progression-free survival in HCC patients who have failed sorafenib therapy. However, one of the primary factors limiting regorafenib's clinical utilization is toxicity. Using Clinical Trials.gov and PubMed, we gathered clinical data on regorafenib and conducted a extensive analysis of the medication's adverse reactions and mechanisms. Next, we suggested suitable management techniques to improve regorafenib's effectiveness.

AREAS COVERED

We have reviewed the mechanisms by which regorafenib-induced toxicity occurs and general management strategies through clinical trials of regorafenib. Furthermore, by examining the literature on regorafenib and other tyrosine kinase inhibition, we summarized the mechanics of the onset of regorafenib toxicity and mechanism-based intervention strategies by reviewing the literature related to regorafenib and other tyrosine kinase inhibition.

EXPERT OPINION

One of the primary factors restricting regorafenib's clinical utilization and combination therapy is its toxicity reactions. To optimize regorafenib treatment regimens, it is especially important to further understand the specific toxicity mechanisms of regorafenib as a multi-kinase inhibitor.

Tiredness of Life - Conceptualizing a Complex Phenomenon

A phenomenon referred to as 'tiredness of life' or 'weariness of life' appears in current discussions on the legitimacy of euthanasia for relatively healthy older adults as well as in research on suicidality more broadly. However, a consensus conceptualization of the phenomenon is lacking. In the current paper, we offer such a conceptualization by reviewing and integrating knowledge from terminology, available descriptions, and first qualitative findings. Boredom with life, aversion towards life, meaninglessness, and fatigue are identified as central components of the phenomenon. Per component, we describe how the component was identified, our definition of the component and its foundation in descriptions in the literature, and empirical studies on how the component relates to euthanasia requests and suicidality. Moreover, hypotheses on the structure of the phenomenon are outlined, such as on interactions among and the importance of the different components.

The Effect of Reiki on Fatigue Symptoms of Cancer Patients: A Systematic Review

Fatigue is one of the most common symptoms experienced by cancer patients. This systematic review aimed to investigate the effect of reiki on fatigue symptoms of cancer patients. The databases "PubMed," "ScienceDirect," "Scopus," "Web of Science," and "Cochrane Library" were screened between July 12, 2023, and July 25, 2023, using the keywords "Reiki," "Fatigue," and "Cancer" without any restriction to the publication year. The selected studies were evaluated using the Jadad scale, a quality assessment checklist for randomized controlled trials. Among 794 studies initially found, 5 studies meeting the inclusion criteria were included in the present systematic review. Of these studies, 2 were randomized controlled trials, 2 were quasi-experimental studies, and 1 was a cross-over study. It was found that reiki applied to cancer patients in the studies included in the systematic review reduced fatigue while being effective in pain and stress alleviation and improvement of quality of life.

Identifying relevant factors influencing cancer-related fatigue in patients with diffuse large B-cell lymphoma during chemotherapy

BACKGROUND

Diffuse large B-cell lymphoma (DLBCL) is a rapidly growing malignant tumor, and chemotherapy is one of the treatments used to combat it. Although advancements of science and technology have resulted in more and more patients being able to receive effective treatment, they still face side effects such as fatigue and weakness. It is important to thoroughly investigate the factors that contribute to cancer-related fatigue (CRF) during chemotherapy.

AIM

To explore the factors related to CRF, anxiety, depression, and mindfulness levels in patients with DLBCL during chemotherapy.

METHODS

General information was collected from the electronic medical records of eligible patients. Sleep quality and mindfulness level scores in patients with DLBCL during chemotherapy were evaluated by the Pittsburgh Sleep Quality Index and Five Facet Mindfulness Questionnaire-Short Form. The Piper Fatigue Scale was used to evaluate the CRF status. The Self-Rating Anxiety Scale and Self-Rating Depression Scale were used to evaluate anxiety and depression status. Univariate analysis and multivariate regression analysis were used to investigate the factors related to CRF.

RESULTS

The overall average CRF level in 62 patients with DLBCL during chemotherapy was 5.74 ± 2.51. In 25 patients, the highest rate of mild fatigue was in the cognitive dimension (40.32%), and in 35 patients the highest moderate fatigue rate in the behavioral dimension (56.45%). In the emotional dimension, severe fatigue had the highest rate of occurrence, 34 cases or 29.03%. The CRF score was positively correlated with cancer experience (all P < 0.01) and negatively correlated with cancer treatment efficacy (all P < 0.01). Tumor staging, chemotherapy cycle, self-efficacy level, and anxiety and depression level were related to CRF in patients with DLBCL during chemotherapy.

CONCLUSION

There was a significant correlation between CRF and perceptual control level in patients. Tumor staging, chemotherapy cycle, self-efficacy level, and anxiety and depression level influenced CRF in patients with DLBCL during chemotherapy.

Patient-reported symptom burden and circulating cytokines undergoing chemotherapy: a pilot study in patients with ovarian cancer

OBJECTIVE

To analyze the fluctuations of patient-reported outcomes (PROs) and their relationships with cytokines in the peripheral blood of patients undergoing chemotherapy for ovarian cancer (OC).

METHODS

PROs burden was prospectively measured by the M.D. Anderson Symptom Inventory-Ovarian Cancer (MDASI-OC) at baseline before chemotherapy, on a daily basis during and post-chemotherapy days (PCD) 7, 14, and 20. Cytokines were collected at baseline, days prior to hospital discharge and PCD 20. Pearson correlation was used to explore the associations between PROs and cytokines levels in peripheral blood.

RESULTS

The top 8 rated symptoms were compared between the neoadjuvant chemotherapy (NACT) group (n=20) and the postoperative adjuvant chemotherapy (PAC) group (n=7). Before chemotherapy, the mean scores of fatigue and lack of appetite in the NACT group were higher than those in the PAC group. After chemotherapy, pain, nausea, vomiting, disturbed sleep, lack of appetite, and constipation increased to peak during PCD 2-6; while, fatigue and numbness or tingling remained at high levels over PCD 2-13. By PCD 20, disturbed sleep and fatigue showed a significant increase in mean scores, particularly in the NACT group; while, other symptom scores decreased and returned to baseline levels. Additionally, the longitudinal fluctuations in pain, fatigue, and lack of appetite were positively associated with circulating levels of interleukin-6 and interferon gamma (p<0.05).

CONCLUSION

MDASI-OC was feasible and adaptable for demonstrating the fluctuations of symptom burden throughout chemotherapy course. Moreover, symptoms changing along with cytokines levels could provide clues for exploring mechanism underlying biochemical etiology.

A whole food, plant-based randomized controlled trial in metastatic breast cancer: feasibility, nutrient, and patient-reported outcomes

PURPOSE

Quality of life (QOL) is among the most important outcomes for women with metastatic breast cancer (MBC), and it predicts survival. QOL is negatively impacted by cognitive impairment, fatigue, and weight gain. We assessed whether a whole food, plant-based (WFPB) diet-promoting weight loss is feasible and might improve QOL.

METHODS

Women with MBC on stable systemic treatments were randomized 2:1 to 1) WFPB dietary intervention (n = 21) or 2) usual care (n = 11) for 8 weeks. Participants attended weekly education visits and consumed an ad libitum WFPB diet (3 prepared meals/day provided). Patient-reported outcomes and 3-day food records were assessed at baseline and 8 weeks. The effects of WFPB diet on changes in outcomes were assessed by analysis of covariance model controlling for baseline.

RESULTS

20 intervention and 10 control participants completed the trial. Intervention participants were highly adherent to the WFPB diet (94.3 % total calories on-plan). Intervention group nutrient intakes changed significantly including dietary fat (35.8 % to 20.4 % percent calories from fat, p < 0.001) and fiber content (12.7 to 30.8 g fiber/1000 kcal, p < 0.001). Perceived cognitive function (FACT-Cog total + 16.1; 95 % confidence interval [CI] = 0.8-31.7; p = 0.040) and emotional well-being (FACT-B emotional well-being subscale + 2.3; CI = 0.5-4.1; p = 0.016) improved in the WFPB versus the control group. Fatigue, measured by the BFI, improved within the WFPB group for fatigue severity (M = 4.7 ± 2.5[SD] to 3.7 ± 2.3, p = 0.047) and fatigue at its worst (5.8 ± 2.8 to 4.4 ± 2.4, p = 0.011).

CONCLUSIONS

Significant dietary changes in this population are feasible and may improve QOL by improving treatment-related symptoms. Additional study is warranted.

Cancer-related fatigue among patients with advanced cancer receiving immune-checkpoint inhibitors: a prospective study

PURPOSE

The aim of this study was to determine the frequency and factors associated with severity of cancer related fatigue (CRF) as assessed by Functional Assessment of Cancer Illness Therapy-Fatigue (FACIT-F), prior to, and during 12 weeks of immune-checkpoint inhibitors (ICIs). We also explored the effects of ICIs on fatigue dimensions and interference with daily activities (Multidimensional Functional Symptom Inventory, MFSI-SF, Patient-Related Outcome Symptom Measurement Information System Short form Fatigue 7a, PROMIS F-SF), QOL (Functional Assessment of Cancer Therapy-General, FACT-G), and cancer symptoms (Edmonton Symptom Assessment Scale, ESAS).

METHODS

In this prospective, longitudinal observational study, patients with a diagnosis of advanced cancer receiving ICIs were evaluated. Patient demographics, FACT-G, FACIT-F, MFSI-SF, PROMIS F-SF, and ESAS were collected prior to, and during 12 weeks of ICIs.

RESULTS

A total of 160 of the 212 enrolled patients were analyzed. The median age was 61 years, 60% were female, most common cancer was melanoma (73%), and most common ICI was nivolumab 46%. The frequency of clinically significant fatigue (defined as ≤ 34/52 on FACIT-F score) was 25.6% at baseline, 25.7% at week 8, and 19.5% at week 12. There was significant improvement in FACIT-F (P = 0.016), FACT-G physical well-being (P = 0.041), FACT-G emotional well-being (P = 0.011), ESAS anxiety (P = 0.045), and ESAS psychological distress (P = 0.03) scores from baseline to week 12 of ICIs. Multivariate analysis found significant association between clinically significant CRF and PROMIS F-SF (P < 0.001) and MFSI-SF global scores (P < 0.001).

CONCLUSIONS

CRF is frequent prior to the initiation of ICI treatment. Over 12 weeks of ICI treatment, CRF significantly improved. FACT-G physical well-being, FACT-G emotional well-being, ESAS anxiety, and ESAS psychological distress scores improved overtime. Further studies are needed to validate these findings.

Uncertainty affects cancer-related fatigue among breast cancer women undergoing peripherally inserted central catheter chemotherapy: the chain mediating role of psychological resilience and self-care

BACKGROUND

Breast cancer patients undergoing chemotherapy via peripherally inserted central catheter often experience serious behavioral and psychological challenges, with uncertainty and cancer-related fatigue being prevalent issues that profoundly impact prognosis. Therefore, this study aimed to investigate the relationship between uncertainty and cancer-related fatigue by employing a chain mediation model to examine the potential mediating roles of psychological resilience and self-care.

METHODS

A cross-sectional study was conducted with 223 breast cancer patients receiving peripherally inserted central catheter chemotherapy at two tertiary affiliated hospitals of China Medical University in Liaoning, China, from February 2021 to December 2022. Participants completed self-reported questionnaires to assess uncertainty, psychological resilience, self-care, and cancer-related fatigue. The collected data were subsequently analyzed using Pearson's correlation analysis, hierarchical regression analysis, and mediation analysis.

RESULTS

Uncertainty exhibited a significant positive correlation with cancer-related fatigue (p < 0.01) and a negative correlation with psychological resilience (p < 0.01) and self-care (p < 0.01). Uncertainty was found to impact cancer-related fatigue through three pathways: psychological resilience mediated the relationship between uncertainty and cancer-related fatigue (mediating effect = 0.240, 95% confidence interval: 0.188 to 0.298, effect ratio = 53.22%); self-care also mediated this relationship (mediating effect = 0.080, 95% confidence interval: 0.044 to 0.121, effect ratio = 17.74%); furthermore, there was a significant joint mediating effect of psychological resilience and self-care on the association between uncertainty and cancer-related fatigue (mediating effect = 0.042, 95% confidence interval: 0.021 to 0.068, effect ratio o = 9.31%).

CONCLUSION

The findings of this study revealed that uncertainty not only directly influenced cancer-related fatigue, but also operated through the mediating effect of psychological resilience, self-care, and sequential mediation of psychological resilience and self-care. Interventions tailored for breast cancer patients receiving peripherally inserted central catheter chemotherapy should target these factors to help alleviate uncertainty, enhance psychological resilience, and improve self-care practices, thereby ameliorating cancer-related fatigue.

Hawthorn with "homology of medicine and food": a review of anticancer effects and mechanisms

Over the past few years, there has been a gradual increase in the incidence of cancer, affecting individuals at younger ages. With its refractory nature and substantial fatality rate, cancer presents a notable peril to human existence and wellbeing. Hawthorn, a medicinal food homology plant belonging to the Crataegus genus in the Rosaceae family, holds great value in various applications. Due to its long history of medicinal use, notable effects, and high safety profile, hawthorn has garnered considerable attention and plays a crucial role in cancer treatment. Through the integration of modern network pharmacology technology and traditional Chinese medicine (TCM), a range of anticancer active ingredients in hawthorn have been predicted, identified, and analyzed. Studies have shown that ingredients such as vitexin, isoorientin, ursolic acid, and maslinic acid, along with hawthorn extracts, can effectively modulate cancer-related signaling pathways and manifest anticancer properties via diverse mechanisms. This review employs network pharmacology to excavate the potential anticancer properties of hawthorn. By systematically integrating literature across databases such as PubMed and CNKI, the review explores the bioactive ingredients with anticancer effects, underlying mechanisms and pathways, the synergistic effects of drug combinations, advancements in novel drug delivery systems, and ongoing clinical trials concerning hawthorn's anticancer properties. Furthermore, the review highlights the preventive health benefits of hawthorn in cancer prevention, offering valuable insights for clinical cancer treatment and the development of TCM with anticancer properties that can be used for both medicinal and edible purposes.

Shenqi Fuzheng injection facilitates skeletal muscle mitophagy mediated by the ubiquitination of HIF-1α to ameliorate cancer-associated fatigue

Cancer-related fatigue (CRF) significantly impacts the quality of life of cancer patients. This study investigates the therapeutic potential of Shenqi Fuzheng injection (SFI) in managing CRF, focusing on its mechanistic action in skeletal muscle. We utilized a CRF mouse model to examine the effects of SFI on physical endurance, monitoring activity levels, swimming times and rest periods. Proteomic analysis of the gastrocnemius muscle was performed using isobaric tags and liquid chromatography-tandem mass spectrometry to map the muscle proteome changes post-SFI treatment. Mitochondrial function in skeletal muscle was assessed via ATP bioluminescence assay. Furthermore, the regulatory role of the hypoxia inducible factor 1 subunit alpha (HIF-1α) signalling pathway in mediating SFI's effects was explored through western blotting. In CRF-induced C2C12 myoblasts, we evaluated cell viability (CCK-8 assay), apoptosis (flow cytometry) and mitophagy (electron microscopy). The study also employed pulldown, luciferase and chromatin immunoprecipitation assays to elucidate the molecular mechanisms underlying SFI's action, particularly focusing on the transcriptional regulation of PINK1 through HIF-1α binding at the PINK1 promoter region. Our findings reveal that SFI enhances physical mobility, reduces fatigue symptoms and exerts protective effects on skeletal muscles by mitigating mitochondrial damage and augmenting antioxidative responses. SFI promotes cell viability and induces mitophagy while decreasing apoptosis, primarily through the modulation of HIF-1α, PINK1 and p62 proteins. These results underscore SFI's efficacy in enhancing mitochondrial autophagy, thereby offering a promising approach for ameliorating CRF. The study not only provides insight into SFI's potential therapeutic mechanisms but also establishes a foundation for further exploration of SFI interventions in CRF management.

Efficacy and safety of selinexor for patients with relapsed and refractory multiple myeloma: A meta-analysis

PURPOSE

Selinexor is a first-in-class, oral selective-inhibitor-of-nuclear-export, granted accelerated approval by FDA (2019) for relapsed and refractory multiple myeloma (RRMM). We sought to quantitatively summarize the selinexor efficacy and safety in RRMM.

METHODS

We searched PubMed, EMBASE, CENTRAL, clinicaltrial.gov, and google scholar, until May 2023, studies about selinexor use in RRMM. The outcome measures of interest were primarily efficacy outcomes, in addition to safety outcomes. Random-effect model analyses were performed, at statistical significance of P<0.05, using the RevMan software.

RESULTS

Meta-analyses of eleven included clinical trials yielded a significant 56.21% overall clinical benefit, 46.91% overall response, 4.89% complete response, 23.41% very good partial response, 24.68% partial response, and 28.06% stable disease rates with selinexor. Due to safety reasons, selinexor caused significant increase in discontinuation rate, 16.80%. Subgroup analyses demonstrated higher efficacy with selinexor plus dexamethasone and proteasome inhibitor combinations than with selinexor alone. The multiple myeloma type, high cytogenetic risk, refractory state, and advanced disease state did not affect performance. Risk of selection, performance, and detection biases were unclear in the included trials.

CONCLUSION

Selinexor led to significant positive responses with an acceptable safety profile in RRMM patients, despite higher rates of safety-related discontinuations. Selinexor-based combinations further enhanced response.

Chronic fatigue in long-term survivors of head and neck cancer treated with radiotherapy

BACKGROUND

There is lack of evidence on chronic fatigue (CF) following radiotherapy (RT) in survivors of head and neck cancer (HNC). We aimed to compare CF in HNC survivors > 5 years post-RT with a reference population and investigate factors associated with CF and the possible impact of CF on health-related quality of life (HRQoL).

MATERIAL AND METHODS

In this cross-sectional study we included HNC survivors treated in 2007-2013. Participants filled in patient-reported outcome measures and attended a one-day examination. CF was measured with the Fatigue Questionnaire and compared with a matched reference population using t-tests and Cohen's effect size. Associations between CF, clinical and RT-related factors were investigated using logistic regression. HRQoL was measured with the EORTC Quality of Life core questionnaire.

RESULTS

The median age of the 227 HNC survivors was 65 years and median time to follow-up was 8.5 years post-RT. CF was twice more prevalent in HNC survivors compared to a reference population. In multivariable analyses, female sex (OR 3.39, 95 % CI 1.82-6.31), comorbidity (OR 2.17, 95 % CI 1.20-3.94) and treatment with intensity-modulated RT (OR 2.13, 95 % CI 1.16-3.91) were associated with CF, while RT dose parameters were not. Survivors with CF compared to those without, had significantly worse HRQoL.

CONCLUSIONS

CF in HNC survivors is particularly important for female patients, while specific factors associated with RT appear not to play a role. The high CF prevalence in long-term HNC survivors associated with impaired HRQoL is important information beneficial for clinicians and patients to improve patient follow-up.

Development of a self-management support practice framework for addressing cancer-related fatigue: a modified Delphi study

PURPOSE

Managing cancer-related fatigue requires individuals to adopt a range of self-management behaviours. However, clinicians report the lack of clear guidance on self-management support practices hinders their provision of supportive care. To develop consensus on a framework of core practices required by health professionals to deliver effective self-management support to cancer patients and survivors experiencing cancer-related fatigue.

METHODS

A preliminary framework of 47 practice items (14 Key Practices, 33 Practice Components) was derived from a systematic review, and a self-management support capability outline for primary care professionals. This preliminary framework was presented for consensus rating and comment in a two-round modified Delphi study conducted with a panel of health professionals, research academics, and cancer consumers.

RESULTS

Fifty-two panel participants comprising consumers (n = 25), health professionals (n = 19), and researchers (n = 16) were included in Round 1 of the modified Delphi study. Feedback from the panel produced consensus on retaining 27 of 47 original practice items without change. Seventeen items (including 12 modified, and 5 newly created practice items) were sent to the panel for rating in Round 2. Thirty-six experts produced consensus on retaining all 17 practice items in Round 2. The final framework comprised 44 items (13 Key Practices, 31 Practice Components).

CONCLUSIONS

The practice framework offers an evidence- and consensus-based model of best practice for health professionals providing self-management support for cancer-related fatigue.

IMPLICATIONS FOR CANCER SURVIVORS

This framework is the first to focus on quality provision of self-management support in managing cancer-related fatigue, one of the most prevalent symptoms experienced by cancer patients and survivors.

Afraid and tired: A longitudinal study of the relationship between cancer-related fatigue and fear of cancer recurrence in long-term cancer survivors

OBJECTIVE

Cancer-related fatigue (CRF) and fear of cancer recurrence (FCR) are two common concerns experienced by cancer survivors. However, the relationship between these two concerns is poorly understood, and whether CRF and FCR influence each other over time is unclear.

METHODS

Data were from a national, prospective, longitudinal study, the American Cancer Society's Study of Cancer Survivors-I (SCS-I). Surveys were completed by 1395 survivors of 10 different cancer types at three time-points, including assessment 1.3 years (T1), 2.2 years (T2) and 8.8 years (T3) following their cancer diagnosis. CRF was assessed using the fatigue-inertia subscale of the Profile of Mood States, and FCR by the FCR subscale of the Cancer Problems in Living Scale. Multiple group random intercepts cross-lagged panel models investigated prospective associations between CRF and FCR.

RESULTS

For younger participants (at or below median age of 55 years, n = 697), CRF at T1 and T2 marginally and significantly predicted FCR at T2 and T3, respectively, but no lagged effects of FCR on subsequent CRF were observed. Cross-lagged effects were not observed for survivors over 55 years of age.

CONCLUSION

Both CRF and FCR are debilitating side effects of cancer and its treatments. Given that CRF may be predictive of FCR, it possible that early detection and intervention for CRF could contribute to lowering FCR severity.

Impact of early integrated rehabilitation on fatigue in 600 patients with breast cancer - a prospective study

BACKGROUND

Fatigue after breast cancer treatment is a common burden that is challenging to treat. The aim of this study was to explore if such integrated rehabilitation program reduces the prevalence of chronic fatigue compared to simple, non-integrated rehabilitation.

PATIENTS AND METHODS

The subjects of our prospective study were 600 female breast cancer patients (29-65 [mean 52 years] of age), who participated in the pilot study on the individualized integrated rehabilitation of breast cancer patients in 2019-2021 and were monitored for one year. The control group included 301 patients and the intervention group numbered 299 patients. The patients completed three questionnaires (EORTC QLQ-C30, -BR23 and NCCN): before cancer treatment, and then six and twelve months after the beginning of cancer treatment. The control group obtained the standard rehabilitation program, while the intervention group was part of the early, individualized multidisciplinary and integrated approach of rehabilitation. The rehabilitation coordinator referred patients for additional interventions (e.g., psychologist, gynecologist, pain management team, physiotherapy, clinical nutrition team, kinesiologist-guided online training, vocational rehabilitation, general practitioner). Data on the patients' demographics, disease extent, cancer treatment and complaints reported in questionnaires were collected and analyzed.

RESULTS

There were no differences between the control and the intervention group of patients in terms of age, education, disease extent, surgical procedures, systemic cancer treatment, or radiotherapy, and also no differences in the fatigue before the beginning of treatment. However, patients from the control group had a greater level of constant fatigue than patients from the intervention group half a year (p = 0.018) and a year (p = 0.001) after the beginning of treatment. Furthermore, a greater proportion of patients from the control group experienced significant interference with their usual activities from fatigue than from the intervention group, half a year (p = 0.042) and a year (p = 0.001) after the beginning of treatment. A multivariate logistic regression showed that one year after the beginning of treatment, the only independent factor correlated to fatigue was inclusion into the intervention group (p = 0.044). Inclusion in the intervention group was beneficial-patients from the control group were 1.5 times more likely to be fatigued.

CONCLUSIONS

Early individualized integrated rehabilitation is associated with a lower prevalence of chronic fatigue or fatigue interfering with usual activities in breast cancer patients in comparison to the control group of patients.

Domains and Categories of Needs in Long-Term Follow-Up of Adult Cancer Survivors: A Scoping Review of Systematic Reviews

The number of long-term cancer survivors increases continually. Understanding their needs is crucial to ensure an adequate follow-up. The aim of our study was to summarize the current literature concerning needs and what influences these needs. A scoping review of systematic reviews was conducted according to the recommendations of the Joanna Briggs Institute. Four electronic databases were searched. Of 414 retrieved papers, 11 met the eligibility criteria. Needs were aggregated into six domains (health-related information, health system, mental, practical, relationship and physical) and 15 categories. The lack of adequate information and the lack of access and/or continuity of supportive care were the most prominent needs. Female gender, younger age, a low level of family and/or social support, and higher educational level were identified as risk factors. Employment and relationship status can affect the needs both in a positive and negative way. The weeks or months after the end of the treatments are particularly critical, and needs can be emphasized during this period. The experience of cancer could also lead to positive changes. The variety of needs affects the quality of life of cancer survivors. Needs assessments should be systematically provided to ensure a better awareness of health professionals and to allow an individual, holistic, and integrated follow-up.

New Insights in ATP Synthesis as Therapeutic Target in Cancer and Angiogenic Ocular Diseases

Lactate and ATP formation by aerobic glycolysis, the Warburg effect, is considered a hallmark of cancer. During angiogenesis in non-cancerous tissue, proliferating stalk endothelial cells (ECs) also produce lactate and ATP by aerobic glycolysis. In fact, all proliferating cells, both non-cancer and cancer cells, need lactate for the biosynthesis of building blocks for cell growth and tissue expansion. Moreover, both non-proliferating cancer stem cells in tumors and leader tip ECs during angiogenesis rely on glycolysis for pyruvate production, which is used for ATP synthesis in mitochondria through oxidative phosphorylation (OXPHOS). Therefore, aerobic glycolysis is not a specific hallmark of cancer but rather a hallmark of proliferating cells and limits its utility in cancer therapy. However, local treatment of angiogenic eye conditions with inhibitors of glycolysis may be a safe therapeutic option that warrants experimental investigation. Most types of cells in the eye such as photoreceptors and pericytes use OXPHOS for ATP production, whereas proliferating angiogenic stalk ECs rely on glycolysis for lactate and ATP production. (J Histochem Cytochem XX.XXX-XXX, XXXX).

Intermittent fasting and its impact on toxicities, symptoms and quality of life in patients on active cancer treatment

Intermittent fasting is a dietary intervention that is increasingly being tested for positive outcomes in patients receiving cancer treatment. In this review, we examine the impact of intermittent fasting on symptoms, toxicities, and quality of life in patients undergoing cancer therapy and highlight unmet investigative areas to prompt future research. While current evidence is preliminary and conclusions mixed, some promising clinical studies suggest that intermittent fasting interventions may improve fatigue and reduce gastrointestinal toxicities in certain patients with cancer. Emerging clinical evidence also demonstrates that intermittent fasting may reduce off-target DNA damage, and induce favorable cellular-level immune remodeling. Furthermore, intermittent fasting has the potential to lower hyperglycemia and the ratio of fat to lean body mass, which may benefit patients at risk of hyperglycemia and weight-related adverse effects of some common pharmacological cancer treatments. Larger controlled studies are necessary to evaluate intermittent fasting in relation to these endpoints and determine the effectiveness of intermittent fasting as an adjunct intervention during cancer care. Future cancer trials should evaluate intermittent fasting diets in the context of multimodal diet, exercise, and nutrition strategies, and also evaluate the impact of intermittent fasting on other important areas such as the circadian system and the gut microbiome.

The effect of self-designed metabolic equivalent exercises on cancer-related fatigue in patients with gastric cancer: A randomized controlled trial

AIMS

To investigate the effect of Self-designed Metabolic Equivalent Exercises (SMEE) on cancer-related fatigue in patients with gastric cancer.

METHODS

130 patients with gastric cancer admitted to Department of Oncology of a tertiary hospital in Shanghai were enrolled and assessed for eligibility. After excluding 1 patient who declined to participate, 129 eligible patients were randomly assigned into SMEE (n = 65) and control (n = 64) groups. The Revised Piper Fatigue Scale (RPFS) and EORTC QLQ-C30 Quality of Life Scale were used to measure cancer-caused fatigue and quality of life, respectively, in both groups at the first admission and after 3 months.

RESULTS

After excluding patients who did not receive allocated intervention due to medical (n = 3) and personal (n = 2) reasons, those who were lost to follow-up (n = 3), and those who had discontinued intervention (n = 2), 119 patients (64 in the SMEE group and 55 in the control group) were included for analysis. There were no statistically significant differences in the RPFS or QLQ-C30 score between the two groups at baseline. After 3 months, the total RPFS score of the SMEE group was significantly lower than that of the control group (2.86 ± 1.75 vs. 4.65 ± 1.29, p = 0.009), with significant improvements in affective meaning (0.83 ± 0.92 vs. 1.13 ± 0.77, p = 0.044) and sensory (0.70 ± 0.71 vs. 1.00 ± 0.54, p < 0.001) subscales; in the SMEE group, QLQ-C30 scores in somatic (2.00 ± 0.27 vs. 1.31 ± 0.26, p < 0.001), emotional (2.67 ± 0.58 vs. 2.07 ± 0.48, p < 0.001), and social (3.23 ± 0.58 vs. 1.64 ± 0.51, p < 0.001) functioning were significantly higher than those in the control group, with significant improvements in fatigue (p < 0.001), nausea/vomiting (p = 0.014), shortness of breath (p < 0.001), constipation (p < 0.001), and diarrhea (p = 0.001) dimensions.

CONCLUSION

The self-programmed metabolic equivalent manipulation as an exercise intervention could effectively reduce the degree of cancer-caused fatigue and improve quality of life in patients with gastric cancer.

Cancer-related fatigue and activities of daily living: lessons learned from the COVID-19 pandemic

BACKGROUND

Cancer-related fatigue is a prevalent condition in all stages of oncologic disease that is poorly diagnosed, with a negative impact on physical function to perform activities of daily living. Fatigue is also one of the main manifestations in post-COVID-19 syndrome, and few studies have explored the functionality of cancer patients after infection by the new coronavirus. This study was designed to assess cancer-related fatigue symptoms and their implications on physical function and quality of life during the pandemic.

METHODOLOGY

An observational study with a cross-sectional survey in cancer patients ≥ 18 years of age was conducted. The Functional Assessment of Chronic Illness Therapy - Fatigue Scale (FACIT-F), the perception of asthenia and performance status were evaluated, and the differences between groups according to the history of COVID-19 were calculated.

RESULTS

A total of 60 cancer patients had an average age of 33.5 ± 10.11 years, 73.3% were female, and 98.3% had an Eastern Cooperative Oncology Group-Performance Status level < 2. Severe fatigue was found in 43.3% of patients, and the average FACIT-F score was 33.5 ± 10.11. The proportion of coronavirus infection was 13,3%, and the performance of this group was worse on the scale compared to the group without infection (25 ± 10,40 vs. 34,81 ± 9,50 [p = 0,009]). There was a significant correlation between visual analog scale values and FACIT-F scale scores (Pearson's r = -0.76).

CONCLUSION

SARS-CoV-2 infection could increase cancer-related fatigue symptoms, limiting activities of daily living and impairing quality of life.

Preclinical Multi-Omic Assessment of Pioglitazone in Skeletal Muscles of Mice Implanted with Human HER2/neu Overexpressing Breast Cancer Xenografts

Breast cancer (BC) is the most prevalent cancer worldwide and is accompanied by fatigue during both active disease and remission in the majority of cases. Our lab has measured fatigue in isolated muscles from treatment-naive BC patient-derived orthotopic xenograft (BC-PDOX) mice. Here, we conducted a preclinical trial of pioglitazone in BC-PDOX mice to determine its efficacy in ameliorating BC-induced muscle fatigue, as well as its effects on transcriptomic, metabolomic, and lipidomic profiles in skeletal muscle.

Methods

The pioglitazone and vehicle groups were treated orally for 4 weeks upon reaching a tumor volume of 600 mm3. Whole-animal indirect calorimetry was used to evaluate systemic metabolic states. The transcriptome was profiled using short-read bulk RNA sequencing (RNA-seq). Liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to profile the metabolome and lipidome. Fast and slow skeletal muscle function were evaluated using isolated ex vivo testing.

Results

Pioglitazone was associated with a significant overall decrease in metabolic rate, with no changes in substrate utilization. RNA-seq supported the downstream effects of pioglitazone on target genes and displayed considerable upregulation of mitochondrial bioenergetic pathways. Skeletal muscle metabolomic and lipidomic profiles exhibited dysregulation in response to BC, which was partially restored in pioglitazone-treated mice compared to vehicle-treated BC-PDOX mice. Despite molecular support for pioglitazone's efficacy, isolated muscle function was not affected by pioglitazone treatment.

Conclusions

BC induces multi-omic dysregulation in skeletal muscle, which pioglitazone partially ameliorates. Future research should focus on profiling systemic metabolic dysfunction, identifying molecular biomarkers of fatigue, and testing alternative pioglitazone treatment regimens.

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

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

The association between the gut microbiome and fatigue in individuals living with cancer: a systematic review

PURPOSE

Fatigue is the most distressing symptom for individuals with cancer. While numerous studies have investigated biological pathways that could underlie the mechanism of fatigue, the cause of fatigue remains unclear. This review aimed to investigate the association between gut microbial composition and fatigue in individuals with cancer.

METHODS

Medline (PubMed), Embase (Elsevier), and CINAHL Complete (Ebscohost) were systemically searched on March 30, 2023, for articles investigating gut microbial composition (relative abundance, alpha diversity, and beta diversity) and fatigue in individuals with cancer; no limitations were placed on dates, participant age, nor cancer type/treatment.

RESULTS

Microbial composition in the form of relative abundance was correlated with fatigue in six of the seven articles. A high relative abundance of g_Ruminoccocus was observed in individuals with low fatigue. An elevated relative abundance of g_Escherichia and f_Enterobacteriaceae was associated with high fatigue. However, other associations between fatigue and relative abundance composition, such as with g_Bifidobacterium and g_Faecalibacterium, had conflicting results. For alpha diversity and fatigue, the findings were contradictory; the association between beta diversity and fatigue was unclear due to conflicting results.

CONCLUSIONS

Pro-inflammatory bacteria, such as f_Enterobacteriaceae, were more commonly associated with higher fatigue scores, while anti-inflammatory or short-chain fatty acid producing bacteria, such as g_Ruminoccocus, were linked with lower fatigue scores in individuals with cancer. The relationship between alpha and beta diversity and fatigue was inconclusive. Further investigation is needed to clarify whether gut microbial changes play a correlative or causal role in the development of fatigue in individuals with cancer.

5-EPIFAT trial protocol: a multi-center, randomized, placebo-controlled trial of the efficacy of pharmacotherapy for fatigue using methylphenidate, bupropion, ginseng, and amantadine in advanced cancer patients on active treatment

BACKGROUND

Cancer-related fatigue (CRF) is still undertreated in most patients, as evidence for pharmacological treatments is limited and conflicting. Also, the efficacy of the pharmacological agents relative to each other is still unclear. Therefore, medications that may potentially contribute to improving CRF will be investigated in this head-to-head trial. Our main objective is to compare the efficacy of methylphenidate vs. bupropion vs. ginseng vs. amantadine vs. placebo in patients with advanced cancer.

METHODS

The 5-EPIFAT study is a 5-arm, randomized, multi-blind, placebo-controlled, multicenter trial that will use a parallel-group design with an equal allocation ratio comparing the efficacy and safety of four medications (Methylphenidate vs. Bupropion vs. Ginseng vs. Amantadine) versus placebo for management of CRF. We will recruit 255 adult patients with advanced cancer who experience fatigue intensity ≥ 4 based on a 0-10 scale. The study period includes a 4-week intervention and a 4-week follow-up with repeated measurements over time. The primary outcome is the cancer-related fatigue level over time, which will be measured by the functional assessment of chronic illness therapy-fatigue (FACIT-F) scale. To evaluate safety, the secondary outcome is the symptomatic adverse events, which will be assessed using the Patient-Reported Outcomes version of the Common Terminology Criteria for Adverse Events in cancer clinical trials (PRO-CTCAE). Also, a subgroup analysis based on a decision tree-based machine learning algorithm will be employed for the clinical prediction of different agents in homogeneous subgroups.

DISCUSSION

The findings of the 5-EPIFAT trial could be helpful to guide clinical decision-making, personalization treatment approach, design of future trials, as well as the development of CRF management guidelines.

The effect of a fatigue self-management program based on individual and family self-management theory in cancer patients: A single-blinded randomized controlled trial

PURPOSE

This study was conducted to investigate the effect of the Fatigue Self-Management Program based on the Individual and Family Self-Management Theory on fatigue, daily living activities, and well-being in cancer patients.

METHODS

This randomized controlled single-blind experimental study was carried out between November 2020 and April 2022. A total of 94 patients with advanced cancer, 47 in each group, were included in the study, and 57 participants completed the study. Data were collected using the Brief Fatigue Inventory, Katz Index of Independence in Activities of Daily Living, and Well-Being Questionnaire-22. The Fatigue Self-Management Program based on Individual and Family Self-Management Theory was delivered to the intervention group with two face-to-face and two tele-monitoring sessions. No intervention was applied to the control group, who received only routine care.

RESULTS

The mean score of fatigue in the intervention group compared to the control group decreased, and the difference was statistically significant (p < .05); daily living activities mean scores were higher than the control group, but there was no statistically significant difference (p > .05). The mean scores of depression and anxiety in the intervention group were lower than those in the control group; energy, positive well-being, and general well-being mean scores were found to be higher than those in the control group, and the difference was statistically significant (p < .05).

CONCLUSIONS

The Fatigue Self-Management Program effectively reduces the fatigue experienced by cancer patients and increases their well-being but it does not increase their independence in daily living activities.

Understanding experiences of cancer-related fatigue in patients with lung cancer after their cancer treatment: a qualitative content analysis

PURPOSE

Cancer-related fatigue (CRF) is an important symptom affecting the quality of life of patients with lung cancer. However, research on the characteristics of CRF in lung cancer and their relationship to cancer treatment is limited. We aimed to explore the unique features of CRF in patients with lung cancer, and investigate the influencing factors.

METHODS

Semi-structured interviews were conducted with 21 adult patients with lung cancer until data saturation was reached. The collected data were analyzed using qualitative content analysis. An inductive coding process and deductive content analysis incorporating the established CRF domains were employed. Patient data from electronic medical records were used for data triangulation.

RESULTS

The analysis revealed five themes of CRF: (1) energy depletion, the double burden of illness and treatment, and daily life impediments; (2) feeling down and anxious; (3) neurovascular disturbances and changes in sensory perception; (4) cognitive impairment; and (5) personal and social isolation. CRF tended to improve over time, except for persistent emotional fatigue beyond 6 months. Patients who underwent surgery followed by adjuvant cancer treatment exhibited the most diverse CRF symptoms. The concurrent chemoradiation therapy group experienced significant physical fatigue, whereas the radiosurgery group reported distinct emotional fatigue. Certain factors, such as exercise, can serve as both alleviating and aggravating factors for CRF.

CONCLUSION

Tailored interventions that take into account the multidimensional symptoms of CRF and patient characteristics are crucial. These findings will guide healthcare professionals when implementing patient-centered symptom management and patient education.

[Oncological Rehabilitation for Breast Cancer]

As a result of increasingly individualized and multimodal therapy, prognosis of breast cancer has improved significantly over the last years. However, multimodal treatment and the use of new medications can lead to a variety of somatic, sometimes new, side effects such as fatigue, polyneuropathy or autoimmune toxicities. This and the oncological diagnosis lead to a high level of psychological distress in the women affected and often to subsequent psychological disorders (sleep/anxiety disorders, depression, ...). Both the diverse complaints after oncological therapy and the increasingly improved overall prognosis underline the importance of multimodal rehabilitation concepts to improve quality of life and successful professional reintegration.In the following, these secondary disorders after breast cancer, their multimodal therapy and their significance for social-medical performance assessment are presented in more detail.

Microbiome-Modifiers for Cancer-Related Fatigue Management: A Systematic Review

OBJECTIVES

This study systematically investigates the evidence regarding the use of probiotics in managing cancer-related fatigue (CRF).

STUDY DESIGN

We conducted a systematic review of randomized controlled trials.

DATA SOURCES

The systematic search encompassed six databases: PubMed, CINHAL, Cochrane Database of Systematic Reviews, Web of Science, Scopus, and EMBASE, covering the period from inception to December 2023. The assessment of risk of bias employed the Cochrane risk of bias tool (RoB 2). A narrative synthesis and an exploratory meta-analysis were conducted to summarize the evidence.

RESULTS

Among 460 records, three studies met the eligibility criteria and were included in the review. These studies involved a total of 284 participants with colorectal and breast cancer. One study demonstrated a marginal improvement in CRF postchemotherapy in colorectal cancer patients using probiotics. Another study, also using probiotics, reported a significant reduction in CRF among colorectal cancer patients undergoing chemotherapy. Additionally, a study employing synbiotics showed a substantial decrease in CRF severity in breast cancer patients receiving chemotherapy.

CONCLUSION

The study presents initial but varied evidence suggesting the potential of probiotics and synbiotics as adjunctive therapies in managing CRF alongside anticancer treatments.

IMPLICATIONS FOR NURSING PRACTICE

In nursing practice, large-scale clinical trials are urgently needed to evaluate the effectiveness of probiotics in treating cancer-related fatigue during cancer therapy. Insights from this review could guide nurses in selecting appropriate probiotic strains and integrating microbiome modifiers into comprehensive care plans, potentially enhancing the quality of life for cancer patients.

Identifying central symptom clusters and correlates in patients with lung cancer post-chemotherapy: A network analysis

Objective

This study aims to investigate the network structures of symptoms and symptom clusters in patients with lung cancer post-chemotherapy, with a focus on identifying the central symptom cluster. Understanding the central cluster is crucial for targeted and effective symptom management.

Methods

Symptom occurrence and severity were assessed using the Memorial Symptom Assessment Scale (MSAS). Principal component analysis (PCA) was employed to explore symptom clusters, while network analysis unveiled the network structure and pinpointed the central symptom cluster.

Results

The study included 512 patients with lung cancer. Four distinct symptom clusters emerged: sickness behavior, psychological, lung cancer-specific, and epithelial. The sickness behavior symptom cluster was identified as the central symptom cluster.

Conclusions

This research designates the sickness behavior symptom cluster as central in post-chemotherapy patients with lung cancer, offering valuable insights for clinical nurses in devising more effective symptom management strategies.

Cancer-related fatigue: Quality, credibility, usability, and readability of information on websites of health care institutions in Germany

OBJECTIVES

This study aimed to portray available information on cancer-related fatigue on German health care institution websites considering the idea of patient empowerment.

METHODS

Based on website quality criteria, we developed a website-rating tool comprising 18 items. Descriptive analyses, a KruskalWallis test, and corresponding post hoc tests comparing rating sum scores between institution groups were performed.

RESULTS

Websites of 283 systematically compiled health care institutions were included in the rating. Cancer-related fatigue was introduced on 21.9% and detailed information was provided on 27.9% of the websites. Information material was offered on 9.2% of the websites, while fatigue treatment offers were presented on 21.6% of the websites. The rating sum scores differed between institution groups (p < 0.001), with Comprehensive Cancer Centers scoring significantly higher than the others.

CONCLUSION

The rating revealed an overall sparse provision of information, with fatigue being addressed on less than half of the websites.

PRACTICE IMPLICATIONS

For patients who have access to at least one introduction about fatigue, institutions need to extend their websites. Patients could further be referred to external institutions or information booklets. The naming of contact persons may help linking patients to providers.

A Qualitative Study of the Factors Influencing Patients' Experience of Soft Tissue Sarcoma in the United Kingdom

BACKGROUND

Treatment of soft tissue sarcoma frequently involves extensive surgery, loss of mobility, and complex rehabilitation programs. Poorer patient-reported outcomes are reported in comparison to those from patients with other cancer types. Understanding patient experience is therefore important to support patients and improve care.

OBJECTIVE

The aim of this study was an in-depth exploration of patients' experience of being diagnosed with soft tissue sarcoma.

METHODS

Semistructured interviews and focus groups were conducted with 68 patients with soft tissue sarcoma (59% female; aged 23-82 years). These were analyzed using adapted framework analysis.

RESULTS

Two overarching themes explained the factors influencing patients' experiences: individual and social factors to manage the impact of soft tissue sarcoma; and context and processes of care. Access to professionals with sarcoma expertise and services in specialist hospitals had an impact on patients' well-being. Lack of access to specialist services and coordinated care were associated with worse experiences. These were influenced by age and support from family/friends/other patients and were crucial in patients' adaptation to living with and beyond a sarcoma diagnosis.

CONCLUSION

We describe factors that both negatively and positively influenced the experience of patients with soft tissue sarcoma. Access to specialist soft tissue sarcoma and rehabilitation services and support tailored to patients' age and disease trajectory are needed to improve these experiences.

IMPLICATION FOR PRACTICE

Nurses are important for helping patients manage the long-term effects and directing them to supportive care services. Rehabilitation services need to be available and easily accessible.
