Criteria
Inclusion Criteria:1. Signature of the written informed consent.
2. Histological documentation of breast cancer.
3. Stage I (T1, N0M0), IIA (T2N0M0); IIB (T2N1M0, T3N0M0), IIIA (TXN2M0) and IIIB
(T3N1M0, T4NXM0) primary resectable breast cancer or locally advanced breast cancer.
4. HER2-positive breast cancer, defined as immunohistochemistry (IHQ) 3+ or positive
FISH. When IHQ 2+ HER2 status must be assessed by FISH.
5. The patient granted her consent for taking a biopsy before treatment
6. The patient granted her consent for sending two tumor samples to central laboratory
for molecular sub study.
7. Two weeks prior randomization pregnancy test negative for women of childbearing
potential.
8. Women of childbearing potential must use adequate contraceptive measures during
participation into study. Oral, injectable or implant hormonal contraceptives measure
are not permitted.
9. A World Health Organization (WHO) performance status of 0 or 1 (Karnofsky ≥ 80)
10. Age > 18 years.
11. Absence of metastases disease
12. Baseline Electrocardiography (EKG) 12 weeks prior to randomization. Baseline left
ventricular ejection fraction (LVEF) value within limit of normal value for the
institution or > 50% of basal value
13. Normal laboratory test 2 weeks prior to randomization:
Haematology values: Neutrophil count ≥ 1,5 x109/l; Platelets ≥ 100 x 109/l;
Haemoglobin ≥ 10mg/dl Biochemistry values: serum total bilirubin ≤ 1 x Upper Limit of
Normal (ULN); Aspartate aminotransferase (AST) (SGOT) and Alanine aminotransferase
(ALT) (SGPT) ≤ 2,5 x ULN; alkaline phosphatase ≤ 5 x ULN. Patients which AST and/or
ALT value are > 1,5 x ULN along with alkaline phosphatase value > 2,5 x ULN will be
not included into the study.
Renal function: serum creatinine ≤ 175 µmol/l (2 mg/dl). If the value is borderline,
clearance creatinine must be ≥ 60 ml/min
14. 12 weeks prior to randomization the following assessments and procedures must be
fulfilled: Bilateral mammography; Magnetic resonance imaging (MRI) Breast and
axillary; Chest X-Ray (posterioanterior and lateral); Abdominal ultrasound; Chest
CT-Scan; Abdominal CT-Scan. Bone Scan (if applicable)
15. Patients must be accessible for treatment and follow up
Exclusion Criteria:
1. Patients with lumpectomy, partial mastectomy, modified radical mastectomy are not
allowed to include into study.
2. Prior Immunotherapy, hormonal therapy and chemotherapy for breast cancer is not
allowed.
3. Prior therapy with anthracycline and taxanes (paclitaxel and docetaxel) is not
permitted for any neoplasia.
4. Prior radiotherapy for breast cancer.
5. Bilateral invasive breast carcinoma
6. Pregnant or nursing patients. Negative pregnant test (serum or urine) 14 days prior to
randomization.
7. HER 2 negative breast cancer
8. Patients of childbearing potential must be use adequate contraceptive measures during
study treatment. No hormonal contraceptive measure is permitted.
9. Any M1 breast cancer
10. Any motor or sensorial neurotoxicity grade ≥ 2 according to National Cancer Institute
Common Terminology Criteria for Adverse Events (NCI CTCAE) version 3.
11. Serious cardiac illness or medical conditions: Congestive heart failure, angina
pectoris requiring specific treatment, myocardial infarction 1 year prior to enroll in
the study; poorly controlled hypertension or high-risk uncontrolled arrhythmias.
History of significative neurological or psychiatric disease (psychotic, dementia or
attack) what is unable to patient to grant her informed consent.
Uncontrolled severe Infection Uncontrolled diabetes mellitus, active peptic ulcer
12. Current malignancy or previous malignancy other that breast cancer. Exception cell
carcinoma of the skin no melanoma, carcinoma in situ of the cervix or any other cancer
in the past 10 years.
13. Long term treatment with corticoids except 6 months prior to inclusion in the study
and low doses (≤ 20 mg methylprednisolone or equivalent)
14. Corticoid use contraindication
15. Concomitant hormonal replacement therapy. Previous treatment should be interrupted
before inclusion into study.
16. Cardiopathy what stops patient taking Docetaxel and Trastuzumab: myocardial infarction
recorded; angina pectoris requiring specific treatment; any congestive heart failure
recorded; arrhythmia grade 3 or 4 according to NCI CTCAE version 3; any relevant
valvular disease; chest X ray which shows cardiomegaly or EKG which shows ventricular
hypertrophy unless LVEF value has been ≥ lower normal limit in the last 3 months.
17. Poorly controlled hypertension (systolic > 180 mm Hg or diastolic > 100 mm Hg). The
patients with controlled hypertension under treatment can be included into study
18. Patients under treatment of arrhythmia, angina or congestive heart failure with drug
which modifies cardiac conduction (after digital, beta blocker or inhibitors calcium
channel) are excluded. However if these drugs are took for arterial tension the
patient can be included into study.
19. The patient must interrupt concomitant treatment with hormonal therapy ej. raloxifene,
tamoxifen and selective estrogen receptor modulators (SERM) prior to randomization.
20. Concomitant use of inhibitors and inductors of enzyme CYP3A4 complex (ketoconazole,
itraconazole or grape juice; rifampicin, carbamazepin or fenitoin) are not permitted.
Also, drug are substrate of enzyme CYP2C8 complex is not permitted along with
lapatinib treatment.
