About this study
Official title: Evaluation of Near- InfraRed Imaging of ICG in Comparison With the Lymphoscintigraphic Technique Using Intramammary and Peritumoral Injection of 99mTc-HSA-Nanocolloids for the SLN Detection in BC Patients.
The revision of our data shows that since its introduction in our institution (Jules Bordet Institute) in 1998 (until 2010, the year of the last review of cases), 53 patients underwent neoadjuvant therapy before selective sentinel lymph node dissection followed by conventional axillary dissection.
The analysis of these cases shows that:

- The lack of demonstration of sentinel lymph nodes observed in 8 cases (6 cN0) is associated in 75% of them with a pN+ status
- If scintigraphic imaging is "positive" (demonstration of the sentinel lymph nodes: 35 cN0 and 10 cN+), our results appear favorable with a single false negative SLN result (False Negative Rate = 1/20 or 5%).
Therefore we propose additional technique for LN detection by indocyanine green, we hypothesize that the combination of two different injections improves the technique of sentinel lymph node biopsy.
Read the detailed description
The principal objective of this study is to evaluate the detection rate, the false negative rate and the overall accuracy of the lymphofluoroscopic research of the sentinel lymph nodes after periareolar injections of Indocyanine Green (ICG) in combination and in comparison with our classical intramammary and peritumoral injections of 99mTc-HSA-Nanocolloids in patients with breast cancer. These patients are currently out of the inclusion criteria and still undergo systematically complete axillary node dissection.
In this study (which would include at least 200 patients over a period of 2 years, with at least 100 patients after neoadjuvant chemotherapy) the involved surgeons would continue to perform complete axillary node dissections.
The radioactive SLN would be retrieved ex vivo in the axillary piece (with the gamma probe, after intramammary and peritumoral injections of radiocolloids the day before the surgery, or at least 3 hours before, with scintigraphic preoperative images as already performed routinely for patients described in the introduction 1 of this letter). These radioactive lymph nodes would thereafter been controlled for their possible fluorescence (with our fluorescence camera and after periareolar injection of ICG in the operating room just before the surgery). Finally, in the service of Pathology, all the lymph nodes found by the pathologist in the axillary piece will be controlled for their possible fluorescence.
With this approach, the surgeon will not have to search for SLN and the operative duration will not be extended.
Secondary objectives:
The current literature about the results of SLNB technique has not yet considered the influence of the addition of SPECT-CT imaging (standard approach in our institute since more than 3 years) to planar imaging. In this study, we propose to analyse in a prospective manner the contribution of SPECT-CT: contribution of the analysis of the signal intensity of active lymph nodes on SPECT slides to define a resection threshold corresponding to lymph nodes at risk of being pN+, accuracy for the anatomic localization, better accuracy of the number of SLN on the SPECT-CT versus planar image, better definition of the number of lymph nodes (to be analysed on the CT) covered by a radioactive spot (we have already observed 3 adjacent lymph nodes under one only active spot).
In this last case, such spots covering several lymph nodes would be analysed for the possible fluorescence of each lymph node.
The fluorescence of the detected lymph nodes will be analysed semi-quantitatively and related to their pN+ characteristics (pNi, pNµ, pN1, pNmacro). This first analysis may have major implications when our surgeons will perform an in vivo research of fluorescent SLN (see also Bourgeois et al. 2003).
Finally, we propose to analyse the kinetic and the vascular characteristics (aspects of the vessels on the images) of ICG migration from its injection point to the axilla. We will try to define possible predictive parameters of extended and/or macroscopic involvement of axillary lymph nodes.

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 3 inclusion and 6 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?
Contact Jean-Marie Nogaret, MD (00322541 ext. 3165, jeanmarie.nogaret@bordet.be), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
false negative rate for each technique (fluorescence and radiocolloids) (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.
