This is a open-labeled, single-arm, Investigator-initiated clinical trial of camrelizumab (an anti-PD-1 antibody) in combination with radiotherapy in patients with early triple-negative breast cancer. We will enroll 60 subjects. This study aims to evaluate the efficacy and safety of camrelizumab combined with radiotherapy in the treatment of early TNBC。
