Study Description

Brief Summary: This study is a single-arm, prospective, open label clinical study for evaluating the efficacy and safety of neoadjuvant pyrotinib and trastuzumab plus Vinorelbine given as neoadjuvant treatment in Trastuzumab-refractory HER2 positive early stage or locally advanced breast cancer.

Detailed Description: Neoadjuvant therapy is the standard treatment for locally advanced breast cancer and is used to reduce tumors to make them operable, and to increase breast-conserving rates. In recent years, the anti-HER2 treatment mode, which is double-blocked by a combination of dual-targeted drugs, has obtained clinical approval in adjuvant therapy and neoadjuvant therapy. Pyrotinib is an oral tyrosine kinase inhibitor targeting both HER-1 and HER-2 receptors. Based on previous clinical studies, we designed the study to explore the possibility of Pyrotinib in combination with Trastuzumab plus Vinorelbine given as neoadjuvant treatment in HER2 positive early stage or locally advanced breast cancer.
