ADVERSE EVENTS, TUMOR
In 10/15 patients (67%), some or all SLNs were already visible transcutaneously (Table Next to the 31/35 preoperatively identified SLNs that were detected during surgery, 6 additional SLNs in five patients were identified (all were both fluorescent and radioactive). The additional six SLNs were probably not detected preoperatively since they were in close contact with each other. For patients three and six, the additional SLNs were already visible transcutaneoulsy with ICG. The additional SLNs of patients six and seven were close to the tumor, which complicated pre- and intraoperative radioactive detection because of the high signal in the injection site. This led to a total of 37 intraoperatively detected SLNs. Of these, 35 (95%) were fluorescent and 37 (100%) were radioactive. Importantly, no adverse events occurred.
