Gastrointestinal Neuroendocrine Tumors of Unknown Primary Site: Report from a Series at a Single Institute Abstract #1285

Introduction: Neuroendocrine neoplasms of unknown primary (NENs-UP) account for 10-13% of all NENs and show different biologic behavior, histologic appearance and clinical outcome.
Aim(s): To describe clinical, histologic characteristics and the diagnostic work-up of NENs-UP.
Materials and methods: Between 2005 and 2015, among 93 metastatic NENs, 17 (11M; median age 64 yrs) presented with histologically proven NENs-UP.

#78 The diagnostic and prognostic value of elevated proGRP levels in well- and moderately differentiated neuroendocrine tumors
Introduction: Chromogranin A (CgA) is the most frequently used marker in well- (grade 1) and moderately (grade 2) differentiated NETs. Although CgA is a more sensitive marker than the 5-HIAA, which was widely used until the last decade, CgA has some limitations. False-positively elevated CgA may occur in renal impairment, atrophic gastritis and during treatment of proton-pump inhibitors. Progastrin-releasing peptide (proGRP) was recently reported as a promising tumor marker for small cell lung cancer. Limited data suggests that ProGRP may be a potential tumor marker in NE tumors.

#81 Gastroenteropancreatic neuroendocrine tumors (GEP-NETs): our experience in a multidisciplinary team in a university hospital
Introduction: Gastroenteropancreatic neuroendocrine tumors (GEP-NETs) have a low incidence and prevalence representing < 2% of all gastrointestinal tumors with a heterogeneous biological behavior and an often complex management.

#90 The prognostic value of FDG-PET scan in neuroendocrine tumors: a retrospective analysis of 46 patients treated in one center
Introduction: Neuroendocrine tumors (NETs) are rare and generally indolent. For diagnostic purposes, the sensitivity of FDG-PET scan is known to be low in this setting, though when positive, its prognostic value is not well-defined in NET.

#141 Incidence of second primary tumors in patients with neuroendocrine tumors
Introduction: Based on epidemiological data from SEER 1950-1999, 22.4% cases of non-carcinoid second primary tumors have been described in patients diagnosed with neuroendocrine tumors. The incidence of this type of tumors varies, depending on the series assessed.

#144 Oxaliplatin-based chemotherapy in patients with advanced neuroendocrine carcinoma: an Italian retrospective multicenter analysis
Introduction: Conventional chemotherapy does not have a well-defined role in well/moderately differentiated (WD) neuroendocrine carcinomas (NECs). Various regimens were evaluated. Cisplatin or carboplatin combined with etoposide are usually indicated in poorly differentiated (PD) NECs. Some evidence exists for oxaliplatin activity in WD and PD NECs, combined with capecitabine or gemcitabine.
