Characteristics of a multigene assay (MammaPrint/Blueprint) to predict early recurrence of hormone receptor-positive, HER2-negative breast cancer: a case‒control study (WJOG16722B)

Compared with patients without recurrence, those with early recurrence showed a significantly higher prevalence of high-risk MP results and Luminal B BP subtype. High-risk MP/Luminal B BP subtype suggested an association with early recurrence in patients with HR + /HER2- early breast cancer.
