E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Evaluate the feasibility of non-invasive intraoperative NIR fluorescence guided SLN detection using the radioactive tracer99mTc-nanocoll in combination with a fluorescent dye in patients with colon cancer |
Identificatien van de schildwachtklier in colon en rectum kanker door gebruik te maken van de fluorescente tracer ICG en radioactieve tracer 99mTc-nanocoll. |
|
E.2.2 | Secondary objectives of the trial |
1.To compare results of NIR fluorescence and radioactive guided detection of SLNs (e.g. total number of SLNs, localization and differentiation between SLNs and non-SLNs by visualisation of connecting lymphatic vessels) 2. To evaluate the (additional) value of NIR fluorescence imaging, as determined by the surgeon. 3. To determine the value of SPECT/CT imaging in SLN detection during the surgical procedure 4. To evaluate the most optimal time of tracer administration 5. To evaluate the accuracy of the SLNs detected with99mTc-Nanocoll and NIR fluorescence 6. Evaluate the lymph node drainage pattern 7. Time of the procedure 8. Experience of the surgeon for using both techniques to detect the SLN procedure 9. Adaptive value of the gamma-probe in detection of the SLN seen on SPECT/CT-scan

|
E.5.1.1 | Timepoint(s) of evaluation of this end point |
Evaluation of the primary end point will be after the surgical procedure when pathological examination of the specimen in completed. |
|
E.5.2 | Secondary end point(s) |
• Preoperative detection rate of SLNs by SPECT/CT scan • Number en location of SLNs seen by SPECT/CT scan at different time points after tracer injection • Adaptive value of preoperative localization of SLNs by SPECT/CT imaging during the surgical procedure. • Number and location of SLNs detected by NIR fluorescence imaging in vivo and ex vivo • Visualization of lymphatic vessels and the possibility of differentiation between first and second echelon lymph nodes. • Pathological status of the detected SLNs. • Amount of metastasis in positive lymph nodes. - Duration of the procedure - Adaptive value of intraoperative SLN detection with the gamma - probe - Experience of the surgeon |
|
E.5.2.1 | Timepoint(s) of evaluation of this end point |
