Aims and objectives To identify the experience of breast cancer survivors regarding cancer‐related fatigue, exercise and exercise adherence. Background Cancer‐related fatigue is a common symptom among cancer survivors that limits quality of life. Despite exercise being recommended as a viable solution to manage cancer‐related fatigue, relatively few research studies on the experience of cancer‐related fatigue and exercise adherence have been conducted. Design This was a qualitative study to identify breast cancer survivors’ experience of cancer‐related fatigue, exercise and exercise adherence. This paper adhered to the COREQ checklist in reporting. Methods Four focus group interviews were conducted with 16 breast cancer survivors who had fatigue score of 4 out of 10 (moderate fatigue) or greater. Ethical approval was obtained and participants met for focus group interview discussion. The interview guide included questions on cancer‐related fatigue, barriers and facilitators of exercising, strategies for exercise adherence and suggestions for a supportive programme. Results Four themes were identified through thematic analysis: (a) The insidious and overpowering nature of cancer‐related fatigue; (b) exercising when experiencing fatigue surrounded by prevailing myths; (c) multiple barriers to exercise; and (d) facilitative factors to continue exercising despite fatigue. Conclusions Participants’ experience of moderate or greater cancer‐related fatigue prevented them from exercising, despite knowing its importance, and limited them to passive activities. Misconceptions that exercise is associated with lymphedema and risk of recurrence, poor psychosocial self‐image and lack of clear knowledge and exercise programmes for cancer survivors further limited adherence to exercise. In contrast, finding comfort and strength through exercising and interacting with other breast cancer survivors were facilitative factors. Relevance to clinical practice The insights shared by breast cancer survivors experiencing cancer‐related fatigue can contribute to developing an exercise adherence programme as a way to manage and alleviate fatigue and establish healthy survivorship care.
Background/Aim: Skeletal muscle mass loss is an emerging concern in oncology. Our systematic review and meta-analysis identified the mean difference in skeletal muscle index pre-to post-chemotherapy and synthesized potential key factors. Materials and Methods: We searched primary original research published through October 2019 in four databases: MEDLINE via PubMed, Scopus, CINAHL, and Embase. Results: Fifteen studies were included, 60% published in the past 2 years (2018)(2019). Advanced non-small cell lung cancer was the most frequently reported cancer, and overall survival the most often identified key related factor. Mean difference in skeletal muscle index during chemotherapy was 2. p=0.00), with muscle loss in males (4.52, p=0.00) about 1.6 times higher than that in females (2.86, p=0.01). Conclusion: Oncologists should recognize sex-specific differences in skeletal muscle mass loss during chemotherapy and consider adjusting treatment accordingly.
Background: Individuals with cancer experience stress throughout the cancer trajectory. Allostatic load (AL), a cumulative multi-system measure, may have a greater value in stress assessment and the associated biological burden than individual biomarkers. A better understanding of the use of AL and its operationalization in cancer could aid in early detection and prevention or alleviation of AL in this population. Purpose: To consolidate findings on the operationalization, antecedents, and outcomes of AL in cancer. Methods: Seven databases (CINAHL, Ovid MEDLINE, Web of Science, APA PsycInfo, Scopus, Embase, and Cochrane CENTRAL) were searched for articles published through April 2020. The NIH tools were used to assess study quality. Results: Twelve studies met inclusion criteria for this review. Although variability existed in the estimation of AL, biomarkers of cardiovascular, metabolic, and immune systems were mostly used. Associations of AL with cancer-specific variables were examined mostly utilizing population-databases. Significant associations of AL with variables such as cancer-related stress, positive cancer history, post traumatic growth, resilience, tumor pathology, and cancer-specific mortality were found. Mini meta-analysis found that a one-unit increase in AL was associated with a 9% increased risk of cancer-specific mortality. Conclusion: This review reveals heterogeneity in operationalization of AL in cancer research and lack of clarity regarding causal direction between AL and cancer. Nevertheless, AL holds a significant promise in cancer research and practice. AL could be included as a screening tool for high-risk individuals or a health outcome in cancer. Optimal standardized approaches to measure AL would improve its clinical utility.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
