8. Signed and dated Informed Consent before the start of specific protocol procedures
9. If of childbearing potential, negative pregnancy test.
10a. Assessment of HER-2 receptor: Patients may have HER-2 negative or positive disease. HER-2 positive disease is defined as HER-2 over expression measured by immunohistochemistry IHC3+ and/or by HER-2 gene amplification according to fluorescent in situ hybridization (FISH) or chromogenic in-situ hybridization (CISH).
10b. Patients randomized to receive trastuzumab must have HER-2 positive disease |

3. Pre-existing motor or sensory neurotoxicity of a severity > grade 2 by WHO criteria
4. Preoperative local treatment for breast cancer (i.e. incomplete surgery, radiotherapy)
5. Prior or concurrent systemic antitumor therapy
6. Other serious illness or medical condition
(a) congestive heart failure or unstable angina pectoris even if it is medically controlled. Previous history of myocardial infarction within 1 year from study entry, uncontrolled hypertension or high risk uncontrolled arrythmias
(b) history of significant neurologic or psychiatric disorders including psychotic disorders, dementia or seizures that would prohibit the understanding and giving of informed consent
(c) active uncontrolled infection.
(d) unstable peptic ulcer, unstable diabetes mellitus or other contraindication for the use of corticosteroids
