Study Description

Brief Summary: This is a prospective, randomized and open-label phase II study, evaluating the efficacy and safety of AT vs TP regimen as neoadjuvant treatment for early HER2-negative breast cancer. Participants will undergo/receive HRD testing after enrollment. HRD-positive patients will be randomly assigned in a ratio of 1:1 to receive AT（Doxorubicin or Epirubicin+docetaxel）or TP（Albumin paclitaxel + Cisplatin or Carboplatin）regimen respectively, followed by surgery. HRD-negative patients will be assigned to receive TP（Albumin paclitaxel + Cisplatin or Carboplatin）regimen if TNBC, or AT（Doxorubicin or Epirubicin+docetaxel）rigemen, followed by surgery.

Detailed Description: This study intends to adopt Simon's two-stage optimal design. In stage 1, 15 HRD-positive and 15 HRD-negative patients will be recruited to receive AT or TP regimen as neoadjuvant therapy. If more than 5 patients in the HRD-positive group achieve pCR(pathological complete response) , the trial expands to stage 2, otherwise the trial terminates. In stage 2, another 31 HRD- positive and 31 HRD-negative patients will be enrolled.
