Fluorescence guided surgery (FGS) using targeted optical agents is an expanding field that shows great potential for aiding diagnosis of metastatic LN. Given variations in fluorescence background, a reference standard for regions of interest is necessary for cross patient comparison. The present study aims to determine whether tissue with native target expression can be used as a background to determine metastatic LN in patients with HNSCC infused with anti-epidermal growth factor receptor (EGFR) targeted imaging agents.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Procedures<\/jats:title>\n            <jats:p>Twenty-two patients infused with panitumumab-IRDye800 or cetuximab-IRDye800 prior to surgery were included. Fluorescence imaging and analysis was performed on resected LNs (<jats:italic>N<\/jats:italic>\u2009=\u2009843) using the submandibular glands (SMG) and skin as reference standard tissue with known EGFR antigen expression.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Results<\/jats:title>\n            <jats:p>Sixteen patients (72.7%) had at least one positive LN on final pathology. The LN to SMG (LN\/SMG) and LN to skin (LN\/skin) ratios were significantly higher in metastatic LN compared to benign LN (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.0001 for both). Using patient-specific ratios to determine an optimal LN\/skin cutoff was the most sensitive (95.2%) and directly comparing the LN\/skin ratio of all patients to determine a cutoff was the most specific (86.3%).<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions<\/jats:title>\n            <jats:p>In HNSCC patients infused with a molecularly targeted fluorescent tracer, endogenous expression of the target antigen can be used as a reference standard to detect LN metastasis.
