简要总结
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.
详细描述
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.

研究组 & 干预措施
Dynamic sentinel node biopsy with 99mTc-nanoscan and ICG-99mTc-nanoscan
The patient first receives a one-time injection with 99mTc-nanoscan, then a one-time injection with ICG-99mTc-nanoscan, both dosage are according to routine care.
干预措施: Sentinel node biopsy with either ICG-99mTc-nanoscan or 99mTc-nanoscan (Drug)
结局指标
主要结局
Concordance between tracers
时间窗: 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.
次要结局
- Concordance between intraoperative fluorescence and radioactive findings(Measured at pre-operative imaging)
- Higher echelon nodes(Measured at pre-operative imaging)
