Официальное название

A Multicenter, Single-arm, Prospective Study of Neoadjuvant Pyrotinib Combined With Trastuzumab，Carboplatin and Paclitaxel for ER+/HER2+ Early or Locally Advanced Breast Cancer

Обзор

This study is a multicenter, single-arm, prospective, open clinical study to evaluate the efficacy and safety of pyrotinib in combination with trastuzumab, albumin paclitaxel, and carboplatin in neoadjuvant therapy for ER+/HER2+ early or locally advanced breast cancer.

Вмешательства

• Препарат pyrotinib,Trastuzumab，carboplatin，Albumin paclitaxel
  Pyrotinib tablets: 320mg qd, oral administration after breakfast, 21 days for 1 cycle, continuous administration of 6 cycles. Trastuzumab: The first cycle was 8mg/kg, the second to sixth cycle was 6mg/kg, 21 days was 1 cycle, continuous administration of 6 cycles. Albuminpaclitaxel: On the first day of cycle 1, 260mg/m2 was given intravenously, 21 days for 1 cycle, and 6 consecutive cycles were given. Carboplatin: Endogenous creatinine clearance was calculated using the Cockcroft formula, wit
