Key clinical point: Obesity increased the risk for recurrence in postmenopausal women with early-stage hormone receptor-positive (HR+) breast cancer (BC) who were treated with aromatase inhibitors (AI).
Major finding: Among patients with AI-treated HR+ BC, the risk for BC recurrence was significantly higher in those with obesity ( adjusted hazard ratio [aHR] 1.18; 95% CI 1.01-1.37 ) and severe obesity ( aHR 1.32; 95% CI 1.08-1.62 ) than in those with a healthy weight.
Study details: Findings are from a nationwide cohort study including 13,230 postmenopausal women with stages I-III HR+ BC who received AI.
Disclosures: This study was supported by the Jeppe Juhl Memorial Foundation, Denmark, and other Danish sources. Jensen MR declared receiving from Novartis meeting expenses and personal fees unrelated to this study.
