title: Neoadjuvant Therapy for Early-Stage Breast Cancer: Current Practice, Controversies, and Future Directions.
abstract: Research in the fields of surgical, medical, and radiation oncology has changed the landscape of neoadjuvant therapy in breast cancer, yet many areas of controversy still exist. When considering whether a patient is a candidate for neoadjuvant therapy, ideally the initial assessment should be multidisciplinary in nature and should include clinical, radiographic, and pathologic evaluation. Optimization of systemic therapy is dependent upon identifying the patient's breast cancer subtype; the best approach may include targeted agents, as well as the determination of eligibility for enrollment into clinical trials that incorporate novel therapeutics or predictive biomarkers. This article will review a variety of surgical and radiation-based strategies for management of early-stage breast cancer, including surgical options involving the breast and axilla, and the role of radiation based on response to systemic therapy. Key areas of controversy include the ideal systemic treatment for different breast cancer subtypes, the surgical and radiotherapeutic approaches for management of the axilla, and the role of pathologic response rates as a surrogate for survival in drug development.
