E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
to identify the diagnostic value of indocyanine green (ICG) fluorescence imaging for SLN mapping versus the standard-of-care radioisotope technetium (99mTc) in the SLN procedure for breast cancer patients |
|
E.2.2 | Secondary objectives of the trial |
To assess the:
-sensitivity of the ICG method and the standard 99mTc method to identify the SLN in breast cancer.
-false negatives of the ICG method and the standard 99mTc method to identify the SLN in breast cancer.
-false positive rate between ICG method and 99mTc method to identify the SLN in breast cancer
-number of SLN identified with ICG compared to the standard 99mTc.
-the difference in pathology of the SLN found by ICG and 99mTc, including the difference between micro- and macro metastasis (Mic and Mac resp.) and isolated tumor cells (ITCs).
- intraoperative visualization of the SLN with the camera by ICG and 99mTc before skin incision.
-transit time and detection time for the use of ICG to detect de SLN
-complications, including wound infection, bleeding and lymphedema, of the combination of the ICG method and the standard 99mTc method to identify the SLN in breast cancer.
-number of adverse events from the combination of ICG and 99mTc |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |

E.5 End points |
E.5.1 | Primary end point(s) |

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
|
E.5.2 | Secondary end point(s) |
- Number of lymph nodes identified with ICG and standard 99mTc.
- Percentage of patients in whom fluorescent SLNs were identified of the total patients with identified SLNs by the standard 99mTc.
- Percentage of SLNs that is fluorescent, but not positive for 99mTc.
- Percentage of SLNs that are not fluorescent but positive for 99mTc.
- Pathology of SLN found by ICG and 99mTc including micro- and macro metastasis and isolated tumor cells (ITCs).
- Percutaneous intraoperative visualization of the SLN and lymph drainage with the camera by ICG before skin incision: yes, weak, no; only lymph vessel, no both lymph vessel and node are not visible.
- Detection time: average time between skin incision and SLN resection in minutes.
- Complication rates from the SN procedure by ICG and 99mTc, including lymph edema, (wound)infection, (temporarily) skin discoloring, bleeding and a mild allergic reaction.
- Number of serious adverse events from ICG and 99mTc, including severe allergic reaction, death or other serious adverse events. |
