What this trial studies

This clinical trial aims to enhance surgical outcomes for breast cancer patients by using fluorescence imaging with the tracer bevacizumab-IRDye800CW. The goal is to visualize tumor tissue during surgery, allowing for real-time decision-making to prevent postoperative tumor-positive margins. Eligible participants are females with localized breast cancer who are advised to undergo breast-conserving therapy. The study will assess the effectiveness of this imaging technique in improving surgical precision and patient outcomes.

Who should consider this trial

Good fit: Ideal candidates for this study are females aged 18 and older with histologically proven localized breast cancer suitable for breast-conserving therapy.

Not a fit: Patients with non-palpable breast tumors or those who have had prior surgery on the affected breast may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the rates of cancer recurrence by ensuring complete tumor removal during surgery.

How similar studies have performed: Other studies utilizing fluorescence imaging in surgical oncology have shown promising results, indicating potential success for this approach.

Eligibility criteria

Show full inclusion / exclusion criteria
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.

Exclusion Criteria:

* Medical or psychiatric conditions that compromise the patient's ability to give informed consent
* Non palpable breast tumor or prior surgery of this breast
* Received an investigational drug within 30 days prior to bevacizumab-IRDye800CW
* 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
