ReviewPrimary systemic therapy in HER2-amplified breast cancer: a clinical review.
Primary systemic therapy (PST) in early breast cancer is utilized in locally advanced breast tumors and when breast-conserving surgery is desirable. In addition, the PST setting provides an opportunity to monitor response including histopathological and biomarker examination of the tumor and host tissues before and after systemic therapy. ⋯ Trastuzumab has also shown promising activity in PST/neoadjuvant studies by achieving high rates of complete pathologic response. This is a review of clinical studies that incorporated trastuzumab in PST and/or neoadjuvant chemotherapy, including the results of recently reported studies using trastuzumab in combination with other novel therapies such as lapatinib or pertuzumab.
