4. ECOG performance status of 0 or 1
5. Willing to give informed consent in writing
6. Willing and able to attend the scheduled study visits and to comply with the study procedures
7. No prior therapy for ipsilateral breast cancer
8. Normal lab parameters: white cell count ≥ 3,000/mm3, hemoglobin ≥ 10mg/dl, platelet count ≥ 100,000/mm3, serum creatinine ≤ 1.5 x institutional ULN, bilirubin ≤ 2.0 mg/dl aspartate aminotransferase/alanine aminotransferase/ alkaline phosphatase ≤ 2 x the upper normal limit (AST< 72 U/l, ALT < 104 U/l, AP < 252 U/l)
9. Adequate Coagulation Parameters with: Prothrombin INR < 1.5; Partial Thromboplastin Time < 1.5 x 34.4 sec (51.6 sec)

10. Female patients of childbearing potential should have a negative serum pregnancy test at screening visit and should use a highly efficient method of birth control for the duration of treatment and until the first menses after a 4 week period after the last dose of study medication. Highly effective birth control methods include:

    • combined (estrogen and progestogen containing) hormonal contraception associated with inhibition of ovulation administered oral, intravaginal or transdermal.
    • progestogen-only hormonal contraception associated with inhibition of ovulation administered oral, as an injectable or implantable formulation.
    • intrauterine device
    • intrauterine hormone-releasing system
    • bilateral tubal occlusion
    • vasectomised partner
    • abstinence from sexual intercourse

Exclusion Criteria:

1. Male patients
2. Patients with stage III-IV breast cancer (AJCC 8th edition)
3. Patients with highly vascularized tumor or important post-biopsy hematoma
4. Previous chemotherapy for breast cancer or other types of cancer within the last five years
5. Other malignancies other than non-melanoma skin cancer, or controlled superficial bladder cancer. In the event of prior malignancies treated surgically, the patient must be considered NED (no evidence of disease) for a minimum of 3 years prior to enrolment
6. Patients with a history of autoimmune disease (inflammatory bowel disease, systemic lupus erythematosus, ankylosing spondylitis, scleroderma, rheumatoid arthritis or multiple sclerosis) other auto-immune or debilitating diseases. Vitiligo is not an exclusion criterion.
7.

9. Legal incapacity or limited legal capacity
10. Patients on steroid therapy > 10 mg prednisone (or equivalent) or other immunosuppressive agents such as azathioprine or cyclosporine A are excluded on the basis of potential immune suppression. Patients must have had 8 weeks of discontinuation of any steroid therapy exceeding > 10 mg prednisone (or equivalent) prior to enrolment
11. Presence of an active acute or chronic infection, including symptomatic urinary tract infection, HIV (as determined by ELISA and confirmed by Western Blot) or viral hepatitis (as determined by HBsAg and Hepatitis C serology)
12. Patient is pregnant or is currently breast-feeding
