#134 Gastrointestinal neuroendocrine tumors: tumor characteristics and long-term clinical outcome in the German NET registry
Introduction: Prognosis of neuroendocrine tumors (NETs) has been difficult to predict due to heterogenous tumor biology, various classification systems, and lack of reliable and recent data due to the rarity of these tumors.

#2922 Clinicopathological Characteristics of Borderline Pulmonary Neuroendocrine Neoplasms
Introduction: According to the WHO 2015 classification pulmonary neuroendocrine neoplasms (NENs) are subdivided in carcinoids and neuroendocrine carcinoma (small cell lung carcinoma and large cell neuroendocrine carcinoma (LCNEC)), based on the presence of necrosis and mitotic index (MI). However, in some NENs a discrepancy is observed between grade of differentiation and proliferation rate.

#561 Determinants of Long-Term Outcome for Rectal NETs from a Large German Multicentre Cohort
Introduction: Neuroendocrine tumors (NET) of the rectum are a rare subgroup of NETs with mostly favorable prognosis. Some, however, tend to have a poorer outcome.

#693 Histopathological Reporting of Neuroendocrine Tumors: A 4-Year Tertiary Referral Centre Experience
Introduction: Histopathological recognition of neuroendocrine tumors (NETs) is straightforward, however, sub-classification, grading and staging is challenging with frequently evolving pathological criteria.

#742 Evaluation of Relevant Factors of Prognosis Among a Large German Multi-Centric Cohort–Results from the German NET Registry
Introduction: Neuroendocrine neoplasms (NEN) are a rare tumor entity with varying biological behavior.

#1219 Changes in Neuroendocrine Tumor Microenvironment with WHO Tumor Grading
Introduction: The microenvironment of neuroendocrine neoplasias (NEN) in view of tumor grading (WHO classification of 2000 und 2010) has not yet been validated. Both classifications distinguish between well and poorly differentiated neuroendocrine tumors, including proliferation rate, mitotic index and histomorphology. The WHO classification of 2000 further evaluates tumor location, size, angioinvasion, invasion of the muscle layer, functionally active tumors and metastases.

#1365 Exploring the Rising Incidence of Gastroenteropancreatic Neuroendocrine Tumors According to the Data from Regional Cancer Registry: A Population-Based Analysis of Epidemiology
Introduction: The incidence of gastroenteropancreatic neuroendocrine tumors (GEP-NETs) is reported to arise worldwide. Similar tendency is observed in Bulgaria during the recent 6 years.
