Work package I: In WP-I, the preferred dose of the agent for imaging of margins in oral cancer will be determined. The signal-to-noise ratio will be determined in dose group A (n=7), which will receive 0.05 mg/kg of the tracer, 16-20 hours before surgery. After an interim evaluation of this ratio, the second dose group B (n=7) will receive either a higher or a lower dosage (to be determined) of the tracer. After inclusion of all patients (n=14), the dose with the highest intraoperative signal-to-noise ratio will be selected. Work package II: In WP-II, an expansion cohort (n=15) will be added to the group of patients that had received the selected dose in WP-I. In this group of 22 patients, it will be determined if FLI can improve the rate of adequate surgical resection margins. As secondary research questions, the following aspects will be assessed: sensitivity, specificity, positive and negative predictive values of FLI; colocalization with immunohistochemistry; change in surgical management; incremental operation time; FLI of excised cervical lymph nodes.
