This study aimed to characterize the impact of metastatic breast cancer (MBC) and cancer treatments on health-related quality of life, treatment satisfaction, and daily productivity from the patient perspective. This was a cross-sectional survey of patients with MBC (USA, n = 200; EU, n = 160). Post-menopausal women aged ≥50 years with hormone receptor positive (HR+), HER2-negative (HER2-) MBC, currently using hormonal therapy (HT) or using chemotherapy (CT) for ≤1 year were recruited. Fifty three percent (n = 191) reported CT and 47% (n = 169) reported HT use. Adjusting for covariates, HT users reported greater health-related quality of life (p < 0.05), greater satisfaction with treatment and better feelings about side-effects (p < 0.001). HT users reported less bother with treatment side-effects (0-5 scale, p < 0.001) and less activity impairment than CT users (p < 0.001). HT was associated with better patient-reported outcomes than CT in first-line MBC management. These findings should be taken into consideration while making treatment decisions for HR+/HER2- MBC.
