Preoperative Radiation Therapy for Chemorefractory Localized Inflammatory Breast Cancer.

Purpose: Inflammatory breast cancer (IBC) is a rare breast cancer subtype. Chemorefractory nonmetastatic IBC, defined by locoregional progression under neoadjuvant chemotherapy, is a rare situation with few therapeutic options. Owing to the rarity of this clinical presentation and the lack of specific data, no specific management guidelines exist.
