Key clinical point: Young age at diagnosis of human epidermal growth factor receptor 2-positive (HER2+) early breast cancer (BC) was not associated with any detrimental prognostic value and had no effect on the efficacy of adjuvant dual anti-HER2 targeted therapy.
Major finding: Young age had no effect on invasive disease-free survival (adjusted hazard ratio [aHR] 1.07; 95% CI 0.84-1.35), regardless of hormone receptor status (positive: aHR 1.10; 95% CI 0.82-1.44 or negative: aHR 0.99; 95% CI 0.62-1.51) and anti-HER2 treatment administered (chemotherapy+trastuzumab+pertuzumab: aHR 1.20; 95% CI 0.83-1.68 or chemotherapy+trastuzumab+placebo: aHR, 0.99; 95% CI, 0.71-1.35).
Study details: Findings are from the phase 3 APHINITY trial including 768 patients aged ≤40 years with HER2+ early BC who were randomly assigned to receive chemotherapy+trastuzumab+placebo or chemotherapy+trastuzumab+pertuzumab.
Disclosures: The APHINITY trial was supported by F Hoffmann-La Roche Ltd/Genentech. Some authors declared receiving research funding, honoraria, grants, or nonfinancial support or serving as advisors, speakers, or consultants for several sources, including Roche/Genentech.
