The effectiveness of exercise and/or nutritional interventions to improve the quality of life of women with breast cancer receiving radiation therapy: a scoping review.

Currently, in Australia, 1 in 8 women are diagnosed with breast cancer. A common adjuvant treatment for breast cancer is radiation therapy (RT). The amalgamation of side effects caused by RT treatment can ultimately affect a patient's quality of life (QoL). With increasing breast cancer survival, a greater focus on the non-lethal consequences of this disease and its treatment is warranted. Exercise and nutrition have proven beneficial in promoting and supporting overall health and managing chronic diseases. Furthermore, exercise has demonstrated improvement and sustainment to QoL. The focus of this scoping literature review was to determine the scale of evidence regarding the effectiveness of exercise and/or nutritional interventions for women with breast cancer receiving radiation therapy. An online search of five databases was conducted to identify studies published between 2000 and 2023. The 58 studies included in the scoping review comprised 46 interventions and 4615 women with breast cancer who received radiation therapy participated. Most studies (90%; n = 52) were 'exercise only' based, 3% (n = 2) were 'nutrition only', and the remaining 7% (n = 4) of studies were combined exercise and nutrition interventions. The findings from this review highlight most studies are dedicated to investigating exercise. Further research is required to fully understand the potential benefits of these interventions and their synergistic impact on the quality of life of women with breast cancer receiving radiation therapy.
