#3828 Role of endoscopic resection margin (R1) in the clinical outcome of patients with neuroendocrine neoplasia

Introduction: Endoscopic resection margin R1 (ER1) describes neoplasia presence at lateral and/or deep margin. Highest rate of R1 resection occurs in duodenal NENs (d-NENs) where advanced resection techniques [endoscopic submucosal dissection (ESD); full thickness resection (EFTR)], are more difficult to apply. In gastric (g-NENs) and rectal NENs (r-NENs), due to favourable anatomy, ESD or EFTR obtain lower rates of R1 resection.

#3300 Clinicopathological characteristics of 83 lymph node negative rectal neuroendocrine tumors

Introduction: Rectal neuroendocrine neoplasms (R-NENs) are rare tumors originating from enteric neuroendocrine cells. In recent decades, the incidence and prevalence of R-NENs have increased year by year. According to the US SEER data, the incidence rate of R-NENs is 1.10 per 100,000 cases, and the prevalence has risen from 1/1 100,000 cases in 193 to 14 per 100,000 in 2012.

#955 Usefulness of the WHO Classification and of the ENETS TNM Staging System to Predict Prognosis in Patients with Rectal NENs

Introduction: WHO classification and TNM staging system have been proposed for rectal neuroendocrine neoplasia (NENs). However, their prognostic accuracy is not validated yet.
