Representative case of a 37-year-old male with a primary jejunal NET grade 2. MIP (a) and trans-axial (b, c) [68Ga]Ga-DOTA-TOC PET/CT images reveal primary NET at the jejunal loop (blue arrow) and multiple small (red arrows) and large (red arrowhead) hepatic metastases with intense uptake. He had high TLR (17.7) and high SUVmax (77.5), predicting a good prognosis. However, he had a poor ECOG performance status (1) and high WTV (112.5), predicting poor prognosis. After lanreotide therapy, no progression was found until 30 months of follow-up
