Due to apparent variability in the dynamics of PSMA-targeted NBs and non-targeted NBs depending on the size of the tumor, tumors were separated into two groups: Group A had tumor volumes between 90 and 670 mm3 (n = 7), and Group B had tumor volumes between 670 and 1100 mm3 (n = 4). This evidence concerns the gene FOLH1 and neoplasm.
