Body size and breast cancer prognosis in relation to hormone receptor and menopausal status: a meta-analysis.

Abstract

Obesity is associated with poor survival after breast cancer diagnosis in individual studies and meta-analyses. Evidence regarding associations of obesity with breast cancer-specific survival (BCSS) and overall survival (OS) in relation to hormone receptor status, or BCSS in relation to menopausal status has not been evaluated in a previous meta-analysis. ............ These findings led us to conclude that there is no evidence showing that the association of obesity with breast cancer outcome differs by hormone receptor or menopausal status. This has implications for studies of weight loss interventions in the adjuvant BC setting.
