Tailoring Treatment for Patients with Inflammatory Breast Cancer.

Abstract

Inflammatory breast cancer (IBC) is a rare but aggressive subtype of breast cancer that has a propensity for locoregional recurrence and distant metastasis and is associated with a disproportionately high percentage of breast cancer deaths. IBC is not resectable at initial diagnosis and trimodality therapy is considered the standard treatment for IBC. This includes systemic therapy upfront, followed by modified radical mastectomy and comprehensive chest wall and regional node radiation. Despite this aggressive multi-modal treatment strategy, the prognosis remains worse in IBC when compared with non-inflammatory locally advanced breast cancers. For patients presenting with de novo stage IV IBC, treatment recommendations vary depending on tumor burden, cancer subtype, and presence of comorbidities. Efforts to improve outcomes in IBC are currently underway; however, progress has been affected by the low incidence of disease and limited number of dedicated studies in this population. Improvements in systemic therapies in breast cancer in general are likely to lead to improvements in IBC as well. More dedicated trials are needed to identify additional treatment strategies that may help to improve prognosis for these patients. Additionally, better frameworks for diagnosis, risk stratification based upon factors such as molecular subtype and response to neoadjuvant therapy, will be important to make further progress in IBC.
