Key clinical point: Low expression of human epidermal growth factor receptor 2 (HER2) protein was associated with improved survival outcomes in patients with early breast cancer (BC).
Major finding: HER2-low expression vs HER2-zero BC was associated with a significant overall survival benefit in the entire population (hazard ratio [HR] 0.83; 95% CI 0.78-0.88) and in the subpopulations of patients with hormone receptor-positive BC (HR 0.83; 95% CI 0.77-0.89) and triple-negative BC (HR 0.78; 95% CI 0.70-0.87).
Study details: Findings are from a meta-analysis of 14 studies including 52,106 patients with early BC.
Disclosures: This study was funded by the National Natural Science Foundation of China and other sources. The authors declared no conflicts of interest.
