NOTE: Patients with a prior malignancy diagnosed greater than 10 years in the past who have been curatively treated with surgery ONLY, WITHOUT radiation therapy or systemic therapy (chemotherapy or
endocrine) are eligible for the study. Patients with any prior diagnosis of breast cancer or melanoma, at any time, are excluded from this study.

3. Any clinically staged T4 tumour, including inflammatory breast cancer;

4. Bilateral tumours;

5. Maximum cumulative dose of doxorubicin >360mg/m2 or maximum cumulative dose of epirubicin >720mg/m2 or any prior anthracyclines unrelated to the present breast cancer;

6. Previous (neo-) adjuvant chemotherapy with peripheral stem cell or bone marrow stem cell support;

7. Any prior mediastinal irradiation except internal mammary node irradiation for the present breast cancer;

8. Patients with positive or suspicious internal mammary nodes identified by sentinel node technique which have not been irradiated or will not be irradiated, or patients with supraclavicular lymph node involvement;

9. Prior anti-ErbB2 (HER2) therapy for any reason, or other prior biologic or immunotherapy for breast cancer;

10. Concurrent anti-cancer treatment, except hormonal therapy or radiotherapy for the present breast cancer;

11. Concurrent anti-cancer treatment in another investigational trial with hormone therapy or immunotherapy unless approved by the Executive Committee;

12. Serious cardiac illness or medical conditions including but not confined to:
– History of documented congestive heart failure (CHF) or systolic dysfunction (LVEF < 50%) ;
– High-risk uncontrolled arrhythmias (ventricular tachycardia, high-grade AV-block, supraventricular arrhythmias which are not adequately rate-controlled);
– Angina pectoris requiring antianginal medication;
– Clinically significant valvular heart disease;
– Evidence of transmural infarction on ECG;
– Poorly controlled hypertension (e.g. systolic >180mm Hg or diastolic >100mm Hg);

13. Other concurrent serious diseases that may interfere with planned treatment including severe pulmonary conditions/illness;

14. Any of the following abnormal laboratory tests immediately prior to randomisation:
– serum total bilirubin;
– alanine amino transferase (ALAT) or aspartate amino transferase (ASAT);
– alkaline phosphatase (ALP);
– serum creatinine;
– total white blood cell count (WBC);
– absolute neutrophil count;
– platelets;

15. Unresolved or unstable serious toxicity from prior adjuvant chemotherapy or radiotherapy;

16. Malabsorption syndrome, disease significantly affecting gastrointestinal function, or resection of the stomach or small bowel, or persons unable to swallow oral medication. Patients with ulcerative colitis are also excluded;

17. Pregnant, lactating (women of childbearing potential must have a negative pregnancy test - urine or serum - within 7 days prior to randomisation);

18. Women of childbearing potential including women whose last menstrual period was <1 year ago (unless surgically sterile) who are unable or unwilling to use adequate contraceptive measures during study

Primary end point (Data source: WHO)

Main Objective: to compare disease-free survival (DFS) in patients with ErbB2 (HER2) overexpressing and/or amplified breast cancer randomised to trastuzumab for one year versus lapatinib for one year versus trastuzumab (12 or 18 weeks, according to the assigned design) followed by a six-week treatment-free interval followed by lapatinib (28 or 34 weeks, according to the assigned design) versus trastuzumab in combination with lapatinib for one year. ;Secondary Objective: The secondary objectives of the study are to evaluate and compare the following criteria between treatment arms: Overall survival (OS), time to recurrence (TTR), time to distant recurrence (TTDR), cumulative incidence of brain metastases as the first site of breast cancer recurrance. In addition the safety and tolerability of all four treatment groups will be evaluated.
Exploraty Translational Research Objective:
To evaluate the quantitiva HER2 protein and/or HER2 domain levels (e.g. presence or absence of p95 HER2 domain or ration of intracellular and extracellular HER2 expression levels) and determine the relationship with response to HER2 targeted agents and clinical outcome. ;Primary end point(s): The primary endpoint for analysis is disease-free survival (DFS) which will be defined as the time from randomisation until the first occurrence of:
1. Breast cancer recurrence at any site;
2. A second primary cancer (invasive contralateral breast or non-breast malignancy);
3. Death from any cause as first event.;Timepoint(s) of evaluation of this end point: not applicable
