What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Sensitivity of Near Infrared Fluorescence Imaging | Sensitivity of real-time near-infrared fluorescence imaging to detect microscopic residual disease in the operating room after complete macroscopic surgical resection. For the calculation of the sensitivity, for each operating room we consider the first section and the last section in which the pathological analysis confirms the presence of microscopic residual disease. Patients for whom near-infrared fluorescence imaging detects disease are classified as true positives (TP). Sensitivity is defined as the number of TP divided by the total number of patients N. | at surgery |
