Perception of the prognostic impact of physical activity among cancer survivors: a narrative review

Purpose Little is known about cancer survivors' perceptions of the prognostic impact of physical activity (PA) and the association between perceptions and PA. Therefore, the present narrative review aimed to identify cancer survivors' perceptions of the prognostic impact of PA, perception barriers, and association with PA. Methods A literature search was performed via PubMed and Scopus with search terms including "physical activity", "cancer survivor", and "perception" in November 2022. Inclusion criteria were studies that investigated cancer survivors' perceptions of the prognostic impact of PA written in English. Studies were excluded for patients undergoing cancer treatment or advanced cancer patients only. Results Our search identified a total of 13,080 articles, and 14 studies met the inclusion criteria. The study sample size ranged from 8 to 1003 participants. Most studies showed that cancer survivors poorly understood the prognostic impact of PA. Perception barriers were cited as a lack of advice from health care professionals (HCPs). Several studies reported a positive association between the perception of the prognostic impact of PA and actual PA. Conclusions This narrative review revealed that most reports showed that cancer survivors have a poor perception of the prognostic impact of PA. In addition, the lack of advice from HCPs may also be contributing to the lack of perception among cancer survivors. Therefore, to increase the amount of PA among cancer survivors, it is necessary to improve the perception of the prognostic impact of PA in both cancer survivors and HCPs.
