How MammaPrint Is Reshaping Treatment Decisions in HR+/HER2– Breast Cancer

Fact checked by: Kirsty Mackay

MammaPrint genomic profiling guides personalized HR-positive breast cancer treatment, helping pharmacists and oncology teams reduce chemotherapy use while protecting outcomes.

In this interview with Pharmacy Times, Lee Schwartzberg, MD, FACP, discusses how genomic profiling with MammaPrint and BluePrint helps identify patients with HR-positive, HER2-negative breast cancer who can safely avoid anthracycline-based chemotherapy without compromising outcomes. He explains how low- and ultralow-risk patients derive sufficient benefit from endocrine therapy alone, whereas high-risk patients benefit from more aggressive regimens, including anthracyclines. Schwartzberg highlights the importance of integrating genomic data with clinical and patient-specific factors to support personalized treatment decisions. He also emphasizes the critical role of pharmacists in multidisciplinary care teams, particularly in guiding testing decisions, educating patients, and managing chemotherapy-related toxicities.
