Brief Summary
This study aims to evaluate the (inter)national implementation of a new diagnostic method for sentinel lymph node (SLN) detection in breast cancer. While Technetium-99m (99mTc) is the current gold standard for SLN detection, it has drawbacks such as limited availability, logistical challenges, radiation exposure, and potential side effects. Extensive research indicates that Indocyanine Green (ICG) is an equally effective and potentially more practical alternative. Conducting this study will help accelerate the implementation of ICG in clinical practice.

Outcome Measures
Primary Outcomes (1)
Identifaction rate
Identification rate is defined as the proportion of patients in whom lymph nodes were identified with the gamma-probe using technetium or the fluorescent signal of ICG.
Perioperatively
Secondary Outcomes (10)
Number of lymph nodes identified
Perioperatively
Percentage of SLNs identified per tracer
Perioperatively
Pathology assesment per SLN
Perioperatively
Detection time
Intraoperatively
Complications
From the time of the SLN procedure up until three weeks of follow-up.
- +5 more secondary outcomes
Study Arms (3)
Phase I: pre-implemtation phase
OTHERSLN biopsy using single tracer techentium (current standard)
Phase II: transition phase
OTHERSLN biopsy using double tracer technetium and ICG (learning curve)
Phase III: post-implementation phase
OTHERSLN biopsy using single tracer ICG (alternative method)
Interventions
During this phase, surgeons will use technetium to identify the SLN as this is the current standard of care. This phase will serve as a control group.
During this phase, surgeons will primarily use ICG to identify the sentinel lymph node (SLN), while technetium will serve as a control. This approach allows surgeons to gain proficiency with ICG-guided SLN biopsy and safely advance through the learning curve.
During this phase, surgeons will use ICG as a singe tracer to identify the SLN.
Eligibility Criteria
You may qualify if:
- Clinically node-negative, DCIS or invasive breast cancer confirmed by biopsy
- Preoperative axillary ultrasound to confirm clinical node-negative status
- Indication for breast cancer surgery with SLNB via axillar incision
- Written informed consent according to ICH/GCP and national regulations.
You may not qualify if:
- Patients \< 18 years old.
- Indication for breast cancer surgery with SLNB via mastectomy incision
- Combined MARI procedure
- Known allergy for Indocyanine Green (ICG) or intravenous contrast or iodine
- History of axillary lymph node dissection
- Hyperthyroidism or thyroid cancer
- Pregnancy or breast-feeding
- Psychological, familial, sociological or geographical factors that could potentially hamper compliance with the study protocol
