Who can take part
You may be able to join if
- Signed written informed consent
- Laboratory requirements within 21 days prior to enrollment: a. Adequate bone marrow function (ANC ≥1.5 x 109/l, platelets ≥100 x 109/l); b. Adequate hepatic function (ALAT, ASAT and bilirubin ≤2.5 times upper limit of normal). Subjects with Gilbert's syndrome may have a total bilirubin ≥2.5 × the ULN range, if no evidence of biliary obstruction exists; c. Adequate renal function: creatinine clearance >50 ml/min estimated using the Cockcroft-Gault equation or MDRD equation, or based on a 24-hour urine collection measurement
- Histologically confirmed primary invasive breast cancer
- Stage II – IIIA primary breast cancer according to TNM-staging (8th edition, AJCC); (largest tumor diameter DCE-MRI ≥ 2cm (cT2-3) and/or cN1-2 confirmed with FNA or histology)
- HER2 overexpression defined as circumferential membrane staining that is complete, intense and in >10% of invasive tumor cells (IHC 3+) on pre-treatment biopsy
- Known estrogen- and progesterone-receptor expression of the invasive tumor a. ER-negative or PR-negative is defined as <10% of invasive tumor cell nuclei are immunoreactive in the presence of evidence that the sample can express ER and/or PR
You likely can't join if
- Inflammatory breast cancer, cT4 and/or cN3 tumors
- Contraindications for MRI
- Occult breast cancer (cT0)
- Bilateral breast cancer
- Current pregnancy or breastfeeding
- Current or previous other malignancy unless treated without systemic therapy and more than five years ago
