- Abstract
Objective: The Exercise Program in Cancer and Cognition (EPICC) Study was a randomized controlled trial (RCT) designed to determine whether six months of moderate-intensity aerobic exercise improves neurocognitive function in women with breast cancer (BC) receiving endocrine therapy (ET)., Methods: Postmenopausal women with hormone receptor+, early-stage BC, within two years post-primary therapy were randomized to the exercise intervention (six months, ≥150 minutes of moderate-intensity aerobic exercise/week) or usual care control condition. Outcomes were assessed at pre-randomization and after intervention completion. Groups were compared using linear mixed-effects modeling., Results: Participants (N=153) were X ¯ = 62.09 ± 8.27 years old, with stage I BC (64.1%) and a median of 4.7 months post-diagnosis. We found a group-by-time interaction (p=0.041) and a trend for the main effect of time (p=0.11) for processing speed with improved performance in the exercise group and no change in the controls. Similar main effects of time were observed for learning and memory (p=0.024) and working memory (p=0.01). Better intervention adherence was associated with improved processing speed (p=0.017)., Conclusions: Six months of moderate-intensity aerobic exercise improves processing speed in postmenopausal women with BC receiving ET who initiate exercise within two years of completing primary therapy (surgery +/- chemotherapy). This is the first large-scale study to examine the effects of aerobic exercise on neurocognitive function in women with BC. Additional research is needed to address the long-term effects of aerobic exercise on cognitive function.
