Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Identification rate of SLNM with preoperative PET/CT imaging and intraoperative NIR fluorescence imaging in patients with colon and rectal cancer. | — |
Secondary
| Measure | Time frame |
|---|---|
| • Preoperative detection rate of SLNs by PET/CT scan • Number of SLNs seen by PET/CT scan at different time points after tracer injection • Adaptive value of preoperative localization of SLNs by PET/CT imaging during the surgical procedure. • Number and location of SLNs detected by NIR fluorescence imaging in vivo and ex vivo • Determination of the optimal volume of 89Zr-Nanocoll • Determination of the optimal preoperative injection time for 89Zr-Nanocoll • Visualization of lymphatic vesselsand the possibility of differentiation between first and second echelon lymph nodes. • Pathological status of the detected (S)LNs. • Amount of metastasis in positive lymph nodes. - Differences in kinetics of the tracer between colon and rectal cancer - Differences in detection rate of the SLN between colon and rectal cancer | — |
