Summary

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.

Conditions

  • HR-positive,HER2-negative Breast Cancer

Interventions

DRUG

TORIPALIMAB INJECTION(JS001 )

Drug A: 240mg intravenous infusion of Toripalimab, once every 3 weeks, the first dosing date was C1D1, followed by the first day of each course for 18 cycles, a total of 1 year. Drugs B and C: Epirubicin was administered intravenously after the dosage was calculated at 90mg/m2 body surface area, cyclophosphamide was calculated at 600mg/m2 body surface area by intravenous micropump, both drugs were administered every 3 weeks, the first administration date was C1D1, and then the first day of each course was administered for 4 cycles. Drug D:albumin paclitaxel was given intravenatically at a dose of 125mg/m2 body surface area, once a week, with the first administration date of C5D1, and then on the first day of each course for 12 cycles.

RADIATION

Stereotactic Body Radiation Therapy (SBRT)
