Cilj: Cilj rada bio je procijeniti doprinos jednofotonske emisijske tomografije / kompjutorizirane somatostatinskih receptora (SR SPECT/CT) s 99mTc-EDDA/HYNIC-Tyr3-oktreotidom (99mTc-Tektrotyd) u dijagnostici i procjeni proširenosti bolesti kod pacijenata oboljelih od neuroendokrinih tumora (NET-ova). Ispitanici metode: Retrospektivno analizirano 120 SR SPECT/CT snimanja patohistološki dokazani...
Melanocortin-1 (MC1) receptor is an attractive melanoma-specific target for the development of α-MSH peptide based imaging and therapeutic agents. In this work a new lactam bridge α-MSH analogue was synthesized and radiolabeled with 99mTc via HYNIC chelator and tricine as co-ligand. Also, stability in human serum, receptor bound internalization and tissue biodistribution in tumor bearing nude m...
Neuroendocrine tumor (NET) occurring in association with other endocrine syndromes forms a distinct entity. The aim was to assess the therapy response profile of the routine peptide receptor radionuclide therapy (PRRT) in this relatively uncommon but clinically challenging subgroup of patients. A retrospective analysis was undertaken from the case records from those who were treated with 177Lu-...

Introduction: Bombesin (BN), a 14-amino acid neuropeptide, shows high affinity for the human GRP (gastrin releasing peptide) receptors, which are overexpressed by a variety of cancers, including prostate, breast, pancreas, gastrointestinal, and small cell lung cancer. Aim was to prepare [6-hydrazinopyridine-3-carboxylic acid (HYNIC0), D-Tyr6, D...
SP94 (SFSIIHTPILPL), a novel peptide, has shown specific binding to hepatocellular carcinoma (HCC) cells. We aimed to investigate the capability of SP94 as a targeting probe for HCC imaging and therapy following labeling with technetium-99m ((99m)Tc) and rhenium-188 ((188)Re). HYNIC-SP94 was prepared by solid phase synthesis and then labeled with (99m)Tc. Cell competitive binding, internalizati...
