DLL3 and neoplasm: Interestingly, among 24 patients with PanNETs who underwent concurrent 68Ga-DOTATATE PET-CT imaging, there was no association between tumor DLL3 IHC positivity and 68Ga-DOTATATE PET-CT characteristics from the corresponding tumor lesion (Data Supplement, Figs S4A and S4C), suggesting DLL3 expression in PanNETs is not mutually exclusive with SSTR PET avidity.
