On the other hand, compared with [68Ga]Ga-ProBOMB5, the diF-Pro14-derived [68Ga]Ga-LW02080 showed a significantly lower tumor uptake (7.36 ± 1.13 vs. 12.4 ± 1.35 %ID/g, p < 0.005), likely due to the inferior GRPR binding affinity of Ga-LW02080 [24]. This evidence concerns the gene GRPR and neoplasm.
