Pathological Complete Response from Pyrotinib Combined with Trastuzumab, Paclitaxel and Cisplatin in a Postpartum Woman with HER2-Positive Locally Advanced Breast Cancer: A Case Report.

ABSTRACT:

Background

Overexpression of human epidermal growth factor receptor 2 (HER2) is associated with aggressive disease and poor prognosis. Traditional HER2-targeted agents can improve clinical outcome and have played an essential role in therapy. Pyrotinib is a newly irreversible tyrosine kinase inhibitor (TKI) that is well developed for the treatment of HER2-positive advanced breast tumors.

Case presentation

A 37-year-old postpartum female was presented at a local hospital and was diagnosed with HER2-positive stage IIIB (cT4N1M0) invasive micropapillary adenocarcinoma in the left breast with left axillary metastatic lymph nodes. The patient failed to respond to two cycles of the doxorubicin plus cyclophosphamide (AC) regimen but achieved clinical partial response (cPR) after 4
