Physical Activity and Survival in Women With Advanced Breast Cancer
Background:
Several empirical investigations have attempted to characterize the effect of physical activity on cancer mortality, but these investigations have rarely focused on patients with advanced breast cancer.
Objective:
The current study examined the hypothesis that greater physical activity is associated with longer survival among women with advanced breast cancer.
Methods:
We conducted a secondary data analysis of a prospective study of 103 patients with stage IV (n = 100) or locally recurrent (n = 3) breast cancer involved in a group psychotherapy trial. Physical activity was assessed at baseline using the Seven-Day Physical Activity Recall questionnaire, and patients were followed until April 1, 2016, at which time 93 of 103 had died.
Results:
Greater physical activity level at baseline was significantly associated with longer subsequent survival time in a Cox proportional hazards model (hazard ratio [HR], 0.90; 95% confidence interval [CI], 0.84–0.97; P
