IBC as a Rapidly Spreading Systemic Disease: Clinical and Targeted Approaches Using the Neoadjuvant Model

Inflammatory breast cancer (IBC) is a rare and aggressive form of invasive breast cancer accounting for 2.5% of all breast cancer cases. It is characterized by rapid progression, younger age of onset as compared with other cancers, local and distant metastases, and lower overall survival. The multidisciplinary management of IBC includes neoadjuvant systemic chemotherapy, surgery, radiotherapy, and hormonal therapy in hormone receptor–positive disease. Pathological complete response represents an important prognostic factor suggesting IBC as the ideal in-vivo model for therapeutic development. Molecular subtyping demonstrated higher frequency of basal-like an HER2 disease in IBC compared with non-IBC indicating the areas of novel therapeutic interventions. The prospective testing of HER2–targeted therapies (eg, trastuzumab and lapatinib) demonstrated the validity of this concept and the potential to change the outcome of this aggressive disease.
