#3081 An Atypical Presentation of a Neuroendocrine Carcinoma of Unknown Origin

Introduction: Neuroendocrine carcinomas (NEC) of unknown primary site are uncommon. Most arise from an occult/clinically undetectable primary. Primary NEC of genitourinary tract are rare. High-grade (HG) carcinoms, are rapidly growing and aggressive but usually responsive to platinum-based combination chemotherapy.

#3057 Epidemiological Features of Patients with NeuroEndocrine Neoplasms (NENs): Preliminary Results of an Observational Study by the Hellenic Society of Medical Oncology (HeSMO)

Introduction: NENs are rare tumors and can grow in almost all tissues. Regardless histological, molecular and imaging characteristics that are indicative of the primary origin, a significant percentage remain of unknown primary.

#2894 Single Institution Experience with Peptide Receptor Radionuclide Therapy (PRRT) in Neuroendocrine Tumors (NET)

Introduction: Neuroendocrine tumors (NETs) are a rare and heterogenous group of tumors with rising incidence. Peptide receptor radionuclide therapy (PRRT) with radiolabeled somatostatin analogue is an encouraging systemic treatment modality with minimum side effects.

#2885 Ectopic Neuroendocrine Carcinoma: An Occult Source of ACTH

Introduction: About 250 cases of ectopic ACTH-producing neuroendocrine carcinoma (ACTH-NEC) have been reported; however metastatic ACTH-NEC of unknown primary is very rare. Usually are characterized by having a large cell, small cell, poorly differentiated or anaplastic cell, and Ki-67 index between 40-90%.
