At the moment, several vector molecules are under investigation for their clinical potential in combination with terbium radionuclides including, somatostatin analogues (DOTATOC, DOTANOC and DOTATATE), prostate-specific membrane antigen ligands (PSMA-617 and PSMA-I&T), and cancer targeting antibodies (rituximab and chCE7). This evidence concerns the gene FOLH1 and cancer.
