#684 Clinical Characteristics and Survival of Neuroendocrine Tumors of Unknown Primary
Introduction: NETs of unknown primary account for 10-15% of NETs. There is limited published literature on this group of NETs.
Conference: 10th Annual ENETS Conference (2013)
Category: Surgical treatment
Presenting Author: Dr Raj Srirajaskanthan
#1285 Gastrointestinal Neuroendocrine Tumors of Unknown Primary Site: Report from a Series at a Single Institute
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.
Conference: 13th Annual ENETS conference (2016)
Category: Epidemiology/Natural history/Prognosis - Descriptive epidemiology
Presenting Author: dr Sara Massironi
#681 The Use of Capsule Endoscopy for Assessment of Neuroendocrine Tumors of Unknown Primary Tumor Location
Introduction: Recent studies suggest that capsule endoscopy (CE) should be implemented in diagnostic work-up in patients suspected to have small bowel (SB) tumors. SB accounts for the primary tumor site in 80%-85% of patients with intestinal neuroendocrine tumors (NET). In 10%-15% of patients diagnosed with metastasized NET, the primary tumor site remains obscure.

#633 Clinical and Prognostic Features of Neuroendocrine Tumor of Unknown Primary Site
Introduction: Neuroendocrine tumors of unknown primary site (NET UPS) are rare and heterogenous tumors with poor prognosis. There is little information available on the treatment and prognosis.

#2832 Lymph Node Merkel Cell Carcinoma without Primary: Long Term Survival
Introduction: Merkel cell carcinoma (MCC) is a rare aggressive cutaneous neuroendocrine carcinoma with a high rate of metastasis. Approximately 5% of MCC are found in the lymph nodes (LNs) without a primary tumor on the skin.

#283 Primary Lymph Node Gastrinoma: A Genuine Entity? Two Case Reports and a Review of the Literature
Introduction: The existence of primary lymph node gastrinoma has been proposed but is controversial. We report two cases (Case A - 37-year-old male, Case B - 43-year-old male) of apparent primary lymph node gastrinoma.

#857 Video Capsule Endoscopy as a Tool to Detect Small Bowel Neuroendocrine Tumors
Introduction: Recent studies suggest that video capsule endoscopy (CE) should be implemented in diagnostic work-up in patients with suspected small bowel tumors. Small bowel is the primary site in 80%-85% of patients with intestinal neuroendocrine tumors (NET). In 10%-15% of patients diagnosed with metastasized NET, the localization of the primary tumors remains obscure.

#2846 Whole Genome DNA Methylation Profiling Identifies Neuroendocrine Tumor Origin
Introduction: Determining the origin of a neuroendocrine tumor (NET) of unknown primary can be challenging. Liver metastases can originate from any organ in the body, while pulmonary NETs can be metastases but also primary tumors. This especially holds true for Multiple Endocrine Neoplasia Type 1 patients, who often have multiple primary pancreatic and intestinal NETs. It is important to know the origin of the primary tumor since resection or ablation is crucial in case of treatment with curative intent. Furthermore, the site of origin determines prognosis, treatment options and eligibility for clinical trials.

#167 Localization of Sporadic Neuroendocrine Tumors by Gene expression Analysis of Their Metastases
Introduction: Primary neuroendocrine tumors (NETs) are rare and often difficult to detect, leading to diagnosis late in their development. Cases in which the primary cannot be located are denoted as CUP-Syndrome.

#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.
