3. Histologically confirmed stage II-III (T1N1-3; T2-4N0-2) invasive breast cancer;
4. ER-negative, PR-negative, and HER2 receptor-negative. Alternatively, if ER and PR expression is less than 10% and HER2 receptor is negative, it is also classified as TNBC;
5. Pathological examination of PD-L1 expression: The Combined Positive Score (CPS) refers to the percentage of PD-L1 positive cells (including tumor cells, lymphocytes, macrophages) in all tumor cells. Our center detected the PD-L1 antibody site as 22C3.

1\) Diagnosed history of heart failure or systolic dysfunction (LVEF less than 50%).2) High risk uncontrolled arrhythmias, such as atrial tachycardia, resting heart rate greater than 100bpm, significant ventricular arrhythmias (such as ventricular tachycardia), or higher-level atrioventricular block (i.e. Mobitz II second or third degree atrioventricular block).3) Angina requiring medication for treatment. 4) Heart valve disease with clinical significance. 5) ECG shows transmural myocardial infarction. 6) Poor control of hypertension (systolic blood pressure greater than 180mmHg and/or diastolic blood pressure greater than 180mmHg after drug treatment) 100mmHg).

9\. Have received immunotherapy and experienced adverse immune events such as immune related pneumonia and myocarditis, which have been determined by researchers to potentially affect the safety of the experimental medication.

10\. Individuals with a known history of allergies to the components of this medication regimen.
