About this study
Official title: Study of the (Intravenously Injected) Indocyanine Green Distribution in Tumour Bearing Breasts and in Axillary Pieces of Dissection of Patients Who Have Received Neoadjuvant Therapy for Histologically Proven Mammary Cancer
We will verify if IV injected ICG may colour breast tumors and axillary lymph nodes after neoadjuvant therapy (chemo- or hormonotherapy)
Read the detailed description
In the operating room:
ICG 0.25 mg/kg will be given as an iv injection at least 20 minutes before the beginning of the operation.
Optionally, dynamic NIR imaging centered on the tumor bearing breast will be acquired during the 15 minutes after injection (in comparison with standards of known fluorescence intensity).
Optionally and in case of tumorectomy, peroperative "in vivo" imaging of the surgical dissection will be acquired. The tumour and/or the mammary piece (and the axillary piece) of dissection will be directly imaged "ex vivo" using the PDE camera (in comparison with standards of known fluorescence intensity).
In the Laboratory of Pathology:
The fresh mammary piece will be processed as usual, but the "gross-thick" sections will be imaged using the PDE and the fluorescent areas will be defined (and later analyzed in comparison with standards of known fluorescence intensity).
After fixation, the tumoral tissues as well as - if identified - non tumoral fluorescent foci will be thereafter processed "as usual".
All the slides obtained will be analyzed using the NIR fluorescent microscope for the presence or not of detectable ICG and the ICG-positive tissues or compartments (vascular spaces, interstitial spaces, normal and/or tumoral cells, macrophages…) will be determined.
If fluorescent foci are identified at the level of the axillary piece, they will be isolated and analyzed like the other lymph nodes. Using the NIR fluorescent microscope, these isolated macroscopically fluorescent structures will be analyzed (lymph node? Other?).
Additionally, metastatic lymph nodes will also be controlled for their microscopic fluorescence or not.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Indocyanine Green in people with Breast Cancer, run by Jules Bordet Institute at 1 site in Belgium.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 2 inclusion and 9 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 24 Jul 2014. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Belgium. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
fluorescence intensity of tumoral lesions, scars and healthy tissues after IV injection of ICG in breast cancer patients after neoadjuvant therapy (time frame: 1 week). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 24 Jul 2014.
