Eligibility Criteria
Inclusion Criteria
- •1\.The patient must have histologically confirmed HER2 positive invasive carcinoma of the breast in the reference laboratory of the participating center. HER2 positive criteria to be applied are those used in the participating countries:
- •\- Belgium: FISH amplification ratio \* 2 in the reference laboratory of the participating center
- •\- The Netherlands: IHC 3\+ or FISH ratio \*2 in the reference laboratory of the participating center
- •2\.The patient must have documented progressive disease and present with at least 2 non\-bone \*target\* metastatic lesions, unequivocally of neoplastic origin with a transaxial diameter greater than 2 cm on the screening diagnostic CT/MRI. These two lesions should not be confluent with adjacent lesions and not have been irradiated previously
- •3\. A concurrent biopsy of a metastatic site is mandatory (with two formalin fixed paraffin embedded (FFPE) core sample and two snap frozen tumor sample) after progression has been documented and before inclusion and the patient agrees with the procedure.
- •4\. Primary tumor blocks (or 11 unstained slides) available for confirmatory central laboratory HER2 testing in Jules Bordet Institute. If available, a snap frozen sample of the primary tumor will also be centralized in Jules Bordet Institute.
- •5\.Age \>\= 18 years
- •6\.Eastern Cooperative Oncology Group (ECOG) performance status (PS) 0 to 1
- •7\.No significant cardiac history and current LVEF \>\= 50%
- •8\.Adequate organ function, evidenced by the following laboratory results:
Exclusion Criteria
- •1\.Patients with bone only metastases are not eligible
- •2\.Diffuse liver (\>\= 50%) involvement on imaging
- •3\.Patients with brain metastasis as the sole site of metastatic disease and/or are symptomatic or require therapy to control symptoms
- •NB: Brain metastasis are allowed provided they are asymptomatic and/or controlled by previous radiotherapy. In case of recent prior brain radiotherapy, there must be evidence on MRI imaging of brain metastatic control for at least 6 weeks since the end of radiotherapy. Moreover, the patient should be at the end of corticosteroid therapy and be clinically asymptomatic.
- •4\.Current uncontrolled hypertension despite medication intake (systolic \> 150 mmHg and/or diastolic \> 100 mmHg)
- •5\.Current unstable angina
- •6\.History of symptomatic CHF of any New York Heart Association (NYHA) criteria or ventricular arrhythmia that requires treatment
- •7\. History of myocardial infarction within the last 6 months
- •8\.History of a decrease in LVEF to \< 40% or symptomatic CHF with previous trastuzumab treatment
- •9\.Current dyspnea at rest due to complications of advanced malignancy, or other diseases that require continuous oxygen therapy
