Physical activity, health-related quality of life, and adjuvant endocrine therapy-related symptoms in women with hormone receptor-positive breast cancer.

Background: Physical activity (PA) is recommended for women with breast cancer (BC); however, data are sparse on the association of PA with quality of life (QOL) and patient-reported symptoms for women on adjuvant endocrine therapy (AET).

Methods: Women with hormone receptor-positive BC who were taking AET completed standardized surveys about their health-related QOL, AET-related symptoms, and levels of PA using validated measures. A Wald chi-square test and an analysis of variance were used to assess associations with PA and independent variables.
