Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Adebrelizumab; Adebrelizumab: 1200mg, iv, d1, q3w, 17 cycles	Drug: Adebrelizumab; Patients undergoing radical surgery to achieve R0 resection were randomised in a 1:1 ratio at 4-16 weeks postoperatively, with patients in the trial group receiving adjuvant treatment with adebrelizumab (up to 17 cycles)

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
DFS	DFS is defined as the time from registration to the first of the following events: local/regional ipsilateral invasive recurrence (or ipsilateral invasive new primary), contralateral invasive breast cancer, distant recurrence, or death from any cause. Patients without an event are censored at the date of last evaluation.	3 years

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
OS	Baseline to measured date of death from any cause	3 years
Incidence of Treatment-Emergent Adverse Events [Safety and Tolerability]	Through continuous monitoring and analysis of the safety data, the drug safety characteristics were evaluated, the suspected and unexpected serious adverse reactions and other major risks were identified in time, and appropriate measures were taken to fully control the risks and protect the safety of the subjects.	3 years
Patient reported outcome (Quality of Life questionnaire of cancer patients)	EORTC Quality of Life-Core 30/18 questionnaire module	At the end of Cycle 1 (each cycle is 21 days)
