NCIt definition : A radioconjugate containing a low molecular weight tracer, DCFBC, specific for prostate-specific
membrane antigen (PSMA) and labeled with the positron-emitting isotope fluorine F
18 with potential prostate tumor imaging upon positron emission tomography (PET).
Upon administration, the DCFBC moiety of fluorine F 18 DCFBC specifically targets
and binds to the tumor associated antigen PSMA, thereby allowing the visualization
of tumor cells expressing PSMA upon PET. PSMA is a transmembrane glycoprotein highly
expressed on malignant prostate epithelial cells and vascular endothelial cells of
various solid tumors.;
