#4593 Excellent response to Ac-225 DOTATATE therapy in a patient with small cell lung cancer

Introduction: Peptide receptor radionuclide therapy (PRRT) is a validated treatment for patients with NETs overexpressing somatostatin receptors (SSTR). IHC analysis indicates that up to 50% of small cell lung cancer (SCLC) tumours are SSTR2 positive and thus can be targeted by SSR imaging and PRRT. Therapy with α-emitting radionuclides, such as Ac225, may offer several advantages over β-emitters by having higher energy transfer and more effective cancer cell death.

#4555 Assessment of gastric mucosa conditions changes in patients with gastric neuroendocrine neoplasia type 1 during gastroprotective therapy

Introduction: Currently, the incidence of gastric neuroendocrine neoplasia (gNEN) has increased significantly. Most gNEN are developed on the background of chronic atrophic gastritis (about 90%). Despite this, the role of chronic atrophic gastritis treatment (gastroprotective therapy) in dynamic of gNEN remains unexplored.

#4456 Characteristics and clinical outcomes after endoscopic or surgical resection of localised sporadic type III gastric NETs: A national study from the French Group of Endocrine Tumors and ENDOCAN-RENATEN network

Introduction: Type III gastric neuroendocrine tumours (gNETs) are rare indolent tumours with increasing incidence. Endoscopic resection has recently been described to be a safe strategy to remove small, localised type III gNETs.

#4425 Ampullary composite gangliocytoma/neuroma and neuroendocrine tumour management

Introduction: Ampullary composite gangliocytoma/neuroma and neuroendocrine tumour (CoGNET), previously called ampullary gangliocytic paragangliomas (GP) are a rare entity, with only few reported cases in the literature.

#4350 Cytoendoscopy for determining the depth of invasion and metastasis of rectal neuroendocrine tumours

Introduction: Rectal neuroendocrine tumours (rNETs) are relatively common submucosal tumours, but even low-grade rNETs can metastasise. The significance of endocytology (EC) in the clinical evaluation of rNETs has not been reported.
