Workflow and tissue sample processing from 23 lymphadenectomies after surgery with [111In]PSMA-617. Resected tissue specimens (consisting out of LN, LNM and fibrofatty tissue) from a total of 275 subregions were analysed with a γ-probe at surgery followed by histopathological analysis. Tracer uptake in tissue samples was analysed with a germanium detector. The asterisk symbol indicates that 8 of 275 subregions were excluded from the analysis because a follow-up PSMA-PET/CT showed the persistence or progression of the PET-positive lesion(s) indicating that the LN(s) had not been removed during surgery
