Overview
The goal of this clinical trial is to intraoperatively visualize tumour tissue in breast cancer patients using fluorescence imaging with the tracer bevacizumab-IRDye800CW and thereby enhance real-time clinical decision making, preventing postoperative tumour-positive margins.
Eligibility
Inclusion Criteria:
- Patients are females with histologically proven carcinoma of the breast
- The carcinoma of the breast is a local disease with limited size (but tumor size ≥ 0.5cm) and in the multidisciplinary tumor board meeting breast conserving therapy is advised.
- Age ≥ 18 years
- Written informed consent has been obtained
- Women of childbearing potential (premenopausal women with intact reproductive organs and women less than two years after menopause) require use of effective contraception at least 3 months before administration of the tracer (if not, a negative serum pregnancy test has to be submitted), and they need to be willing to ensure that she or her partner uses effective contraception during the trial and for 3 months thereafter.

- History of myocardial infarction, cerebrovascular accident, uncontrolled cardiac heart failure or unstable angina within 6 months prior to enrollment
- Inadequately controlled hypertension with or without current antihypertensive medication
- Significant renal or hepatic impairment (grade II or higher deviations by CTCAE)
- History of allergy or infusion reactions bevacizumab or other monoclonal antibodies
- Pregnant or lactating women
- Patients receiving Class IA (quinidine, procainamide) or Class III (dofetilide, amiodarone, sotalol) antiarrhythmic agents
- Life expectancy < 12 weeks
- Preoperatively undetectable lymph nodes using SPECT-scan, requiring the use of patent blue
