title: Management of the Regional Lymph Nodes in Early-Stage Breast Cancer.
abstract: The management of regional nodes in early-stage invasive breast cancer continues to evolve. Improved systemic therapy has contributed to better local regional control, and at the same time it has drawn more attention to its importance. Axillary dissections have decreased, in part because of the increased efficacy of systemic therapy, and also because adjuvant therapy decisions are increasingly driven by biologic characterization of the tumor rather than pathologic nodal information. The trend toward less axillary surgery and a shift toward increased reliance on systemic and radiation therapy to address nodal disease has created interesting questions that were subsequently addressed in recent trials. We review the controversies in regional nodal management, the benefits of current treatment paradigms, the balance between less surgery and more radiation, and the potential tradeoffs vs toxicity.
