Peptide Receptor Radionuclide Therapy in Patients with Metastatic Neuroendocrine Carcinomas: Case Series Abstract #2163

Introduction: High-grade neuroendocrine carcinomas (NECs) possess inevitable tendencies to metastasise and hold poor prospects of survival. Patients with neuroendocrine tumours who progress after medical management can be treated with peptide receptor radionuclide therapy (PRRT), on the proviso that there is positive uptake on 68Ga-DOTATATE PET/CT imaging. Despite this, a proportion of patients who exhibit positive imaging respond poorly to therapy. Management of NECs is currently limited; evidence for treating NECs with PRRT is scarce.
Aim(s): We describe clinical efficacy and safety outcomes in a case series of 5 patients with advanced metastatic NEC treated with 177Lu-DOTATATE PRRT.
Materials and methods: A retrospective, single-centre analysis was conducted, whereby records of patients with NECs who received PRRT were reviewed. Complete biochemical parameters and disease features were captured and treatment outcomes were assessed.

#867 Mixed Adenoneuroendocrine Carcinoma (MANECs): A Rare and Challenging Subgroup of Neuroendocrine Neoplasia
Introduction: Mixed Adenoneuroendocrine Carcinomas (MANECs) are rare entities in which at least 30% of neoplastic cells are neuroendocrine in nature (WHO 2010 classification). They result either from two independent lesions that merge together or are unique lesions with different cell populations intermingled.

#1168 Simultaneous Large Cell Neuroendocrine Carcinoma and Adenocarcinoma of the Stomach: A Case Report and Literature Review
Introduction: Large cell neuroendocrine carcinoma (LCNEC) of the stomach is rare. Gastric NEC occasionally has another component, such as adenocarcinoma, in the same tumor. However, the concurrent occurrence of LCNEC and adenocarcinoma at different sites in the stomach is extremely rare.
