Although observed in a retrospective single-center study, these results reveal a potential advantage of using [68Ga]Ga-DOTA-SST PET/CT in patients with a tumor size > 1 cm, in those cases when histological margins are not tumor-free after endoscopic resection (R1), or when Ki67 is >3% (G2 tumors). This evidence concerns the gene MKI67 and neoplasm.
