ABSTRACT
INTRODUCTION: Physical activity (PA) promotes significant physical and psychosocial benefits for breast cancer survivors. While evidence exists regarding recommendations for the frequency, duration and intensity of exercise that optimise PA benefits for cancer survivors, the role of the environment in achieving optimal outcomes has yet to be determined. This paper presents a protocol for a clinical trial to evaluate the feasibility of a 3-month nature-based walking programme for breast cancer survivors. Secondary outcomes assessed include the impact of the intervention on fitness, quality of life outcomes, and biomarkers of ageing and inflammation. METHODS AND ANALYSIS: The trial is a 12-week single-arm pilot study. Twenty female breast cancer survivors will engage in a supervised moderate intensity walking intervention in small groups in a nature reserve for 50 minutes three times per week. Data will be collected at baseline and end of study, and include assessment of inflammatory cytokines and anti-inflammatory myokines (TNF-α, IL-1ß, IL-6, CRP, TGF-ß, IL-10, IL-13), as well as ageing (DNA methylation, ageing genes) biomarkers; surveys (Patient-Reported Outcomes Measurement Information System-29, Functional Assessment of Cancer Therapy-General, Post-Traumatic Growth Inventory); and fitness assessments (6 min Walk Test, Grip-Strength, One Repetition-Maximum Leg Press). Participants will also complete weekly surveys assessing social support and participate in an exit interview. This is an important first step for future research on the influence of exercise environment on cancer survivor PA outcomes. ETHICS AND DISSEMINATION: This study was approved by the Cedars Sinai Medical Center Institutional Review Board (IIT2020-20). Findings will be disseminated through academic manuscripts, conferences, and community presentations. TRIAL REGISTRATION NUMBER: NCT04896580.

PURPOSE: This study aims to investigate how healthcare providers (HCPs) promote physical activity (PA) to child and adolescent cancer survivors. METHODS: Semi-structured interviews were conducted with HCPs (n = 16; women n = 12; men n = 4) who provide care for cancer survivor youth (age 3 to 18). Participants represented 7 professions, including child life specialists, oncologists, nurse practitioners, physical therapists, and social workers. A reflexive thematic analysis was conducted to explore the techniques that HCPs use to promote PA for this patient population and ways PA promotion can improve. RESULTS: HCPs use five strategies to promote PA to cancer survivor youth: (1) broadening the definition of PA, (2) tailoring PA recommendations, (3) including families, (4) connecting patients to programming, and (5) promoting patient motivation. CONCLUSIONS: This research highlights techniques that HCPs use to promote PA to young cancer survivors and reveals the need for additional ways to support HCPs to improve PA promotion for child and adolescent cancer survivors. While HCPs emphasized the importance of PA for this patient population, they navigate barriers that limit the quality of PA discussions. IMPLICATIONS FOR CANCER SURVIVORS: Further research should explore interventions to improve PA promotion and PA participation among child and adolescent cancer survivors. By understanding the perspectives of HCPs, patients, and their families, PA promotion strategies can be improved, and more programs that support both patients and practitioners may be developed.
