6. ECOG 0-1

7. Adequate hematologic, renal and hepatic function, defined by the following laboratory
results obtained within 14 days prior to randomization/registration:

- Absolute granulocyte count >1.5 x 109/L

- Absolute platelet count >100 x 109/L

- Hemogobin >10 g/dL

- Serum creatinine >1.5 x UNL or a calculated creatinine clearance >50 ml/min

- Serum bilirubin <1.25 UNL

3+ or 2+ with positive FISH/CISH

5. Male patients.

6. Pregnancy, lactation or breastfeeding.

7. Active malignancy at any other side (including contra-lateral synchronous breast
cancer) besides non-melanoma skin cancer or ductal/lobular of the breast or cervix in

tumour diagnosis >5 years prior to registration without any sign of progression at
present time.
