Ex vivo staining of surgical biospecimens from primary and metastatic tumors,as well as involved lymph nodes, demonstrated binding to human tumors.Finally, in an orthotopic tumor model, a simulated clinical workflowhighlighted our unique ability to use standard preoperative nuclearimaging for selecting patients likely to benefit from SSTR2-targetedFGS. The gene discussed is SSTR2; the disease is neoplasm.
