Physical activity in the context of advanced breast cancer: An integrative review

Abstract

Aims To describe and synthesize diverse empirical evidence regarding physical activity (PA) in the context of advanced breast cancer (ABC). Design Integrative review guided by the work of Whittemore and Knafl (2005). Data sources Six electronic databases were systematically searched to identify relevant literature published between January 2007–June 2019. Review methods Abstracts of papers that met the inclusion criteria were reviewed by two researchers and full texts of eligible papers were assessed. Data were extracted by two independent researchers and inter‐rater reliability of data extraction established. Quality of papers was evaluated using the Mixed Methods Appraisal Tool. Data were organized according to comprehensive thematic analysis and the biobehavioural model for the study of exercise interventions. Results Of the 532 abstracts, 18 studies met the inclusion criteria which included six randomized controlled trials, one quantitative non‐randomized study, seven quantitative descriptive studies, three mixed method studies and one qualitative study. Results from studies enrolled fell into four domains: PA performance and its influence on survival; barriers and preferences for PA; interventions to enhance PA; perceived benefits of PA from qualitative feedback. Conclusion Evidence suggests that ABC patients are physically inactive. Main barriers of PA are less aerobic fitness and heavy symptom burden. Simple, tailored and specialist‐supervised PA is preferred by ABC patients. Form of joint self‐instructed and group accompanying is advocated as well. PA intervention programmes identified in this review vary on type, intensity, duration and frequency, while generally, are found to be feasible, safe and beneficial to patients’ physical and psychosocial well‐being. Impact The results propose tailored, supervised, group‐based PA programmes are in urgent need for ABC patients. Clinical professionals should manage more feasible and safer PA interventions to help improve patients’ overall health. More research with rigorous methodology design is warranted to explore PA’s effect on long‐term health outcomes.

PERSPECTIVEs on supervised exercise programs in people with metastatic breast cancer- a qualitative study in four European countries

“…Recent studies have indicated that exercise might also play an important role in supportive care for breast cancer patients with advanced disease. The findings suggest that exercise is generally safe and feasible [ 8 – 11 ] and might positively affect patients’ physical fitness [ 9 , 12 , 13 ], fatigue, and QoL [ 9 , 12 ].…”

Practical factors that influence physical activity in women living with metastatic breast cancer: a qualitative interview study

“…This recent surge of evidence exploring physical activity for metastatic cancers details the quantitative evidence for its bene ts (4,8), but there remains a lack of knowledge around patients' experiences, perceptions and underpinning behavioural context. Presently, the literature around supporting physical activity for women with metastatic breast cancer is heavily weighted towards structured, supervised and/or group-based programs (9). Such approaches to exercise, when achieving an appropriate dose (i.e.…”
