Radiotherapy Followed by Chemotherapy Combined With Toripalimab in Local Advanced HR-positive,HER2-negative BC.

Recruiting now · Phase 2

Conditions studied: HR-positive,HER2-negative Breast Cancer

In brief

This study is the first to explore the clinical study of neoadjuvant radiotherapy followed by chemotherapy combined with terriplizumab in breast cancer. Participants with locally advanced (T1c-T2(≥2cm) N1-2M0 or T3-4cN0-2M0) HR-positive and HER2-negative breast cancer were enrolled to evaluate the efficacy and safety of neoadjuvant radiotherapy followed by chemotherapy combined with triplimab in the treatment of locally advanced HR-positive and HER2-negative breast cancer. About 30 participants are planned to participate in this clinical study.
