Outline of Final Research Achievements

It is unclear what interventions can sustain long-term higher PA to improve breast cancer outcomes. This study aimed to evaluate the long-term effects of interventions on PA after breast cancer treatment. This was a prospective randomized controlled trial evaluating the efficacy of exercise and educational programs on long-term PA compared with usual care. Participants with stageⅠ-Ⅲ, diagnosed breast cancer were randomly assigned in this study. The primary endpoint was recreational PA (RPA) 1 year after registration. From March 16, 2016, to March 15, 2020, patients with breast cancer were registered in the control (n=120), education (n=121), or exercise (n=115) group. There were no significant differences in RPA　and metabolic equivalents/week at 1 year between the exercise and control groups (54% and 53%, P=0.492) and between the education and control groups (62% and 53%, P=0.126).
