#4644 First results of peptide-receptor radionuclide therapy in the Russian population of patients with neuroendocrine neoplasms

Introduction: Peptide-receptor radionuclide therapy (PRRT) has demonstrated its efficacy and safety in a number of clinical trials and has become widely used in the treatment of patients with neuroendocrine neoplasms (NEN) expressing somatostatin receptors.

#4618 The exceptionally rare phenomenon of well-differentiated colon neuroendocrine tumours

Introduction: Colonic neuroendocrine tumours (NETs), excluding rectal NETs, are often described as relatively common and aggressive, with inferior median survival compared to other gastrointestinal (GI) primary sites. However, epidemiological databases may conflate well-differentiated NETs with poorly differentiated NECs, leading to unclear data on prevalence, clinical behaviour, and prognosis of well-differentiated colonic NETs.

#4589 Clinical efficacy of RLT to assess OS and PFS using 177Lu DOTATATE, 90Y DOTATATE, and a mixture of both in patients with advanced, unresectable, progressive rectal NET – A retrospective analysis

Introduction: Retrospective, single-arm, open-label, case series study evaluating the efficacy of different types of radioligand therapy (RLT): 177Lu, 90Y DOTATATE, or mix of both used in advanced, unresectable progressive rectal NETG1/G2.

#4031 68-Gallium DOTANOC PET/CT pitfall in adnexal tumor

Introduction: PET/CT with 68Ga-DOTA is a commonly used tool in the baseline evaluation and follow-up of NETs due to its high specificity and sensitivity, showing better performance than CT in detecting primary and metastatic disease. However, we must know more about its normal physiological distribution, its variation in pathologies, and the possibility of confusion with benign processes to optimize its interpretation.

#3986 The application of 68Ga-DOTANOC PET/CT after endoscopic submucosal dissection for patients with rectal NET

Introduction: Some rectal neuroendocrine tumors (NETs) are accidentally detected by colonoscopy screening. Due to the lack of cognition of endoscopic feature of rectal NET, endoscopic tumor resection has always done without metastasis screening.
