Brief summary
99mTc-nanocolloid, the world wide used hybrid tracer for dynamic sentinel node biopsy, has recently been replaced with 99mTc-nanoscan. The hybrid form (ICG-99mTc-nanoscan) has not yet been validated, to show the similarity between the lymphatic drainage pattern between ICG-99mTc-nanoscan and 99mTc-nanoscan.
Detailed description
The investigators want to set up this study in analogy with the comparison study which was conducted before the introduction of ICG-99mTc-Nanocolloid (99mTc-Nanocoll vs. ICG-99mTc-Nanocoll (NL26699.031.09 -N09DRF). In particular, the investigators want to validate that the hybrid ICG-99m Tc-Nanoscan shows the same preoperative gland involvement on preoperative lymphoscintigraphy and that the intraoperative signal intensities remain the same. All this to maintain the level of current care.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Concordance between tracers | Measured at pre-operative imaging | To demonstrate concordance between the SN visualization of 99mTc-nanoscan and ICG-99mTc-nanoscan on preoperative lymphoscintigraphy and SPECT/CT imaging, expecting an average of 3 sentinel nodes per patient. Discordance is defined as more than 1 sentinel node not detected coherently by the tracers. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Higher echelon nodes | Measured at pre-operative imaging | Number of higher-echelon nodes visualized on preoperative lymphoscintigraphy and SPECT/CT imaging for both tracers (ICG-99mTc-Nanoscan and 99mTc-Nanoscan); |
| Concordance between intraoperative fluorescence and radioactive findings | Measured at pre-operative imaging | Number of the fluorescent nodes at time of excision; \- Number and radioactive signal intensity of the radioactive nodes at time of excision; |
