Treatment Practices in European Centers with Interest in Neuroendocrine Carcinomas and High Grade (G3) Neuroendocrine Tumors

#956

Introduction: Aggressive neuroendocrine neoplasms (NEN) encompass both poorly differentiated carcinomas (NEC) and high grade neuroendocrine tumors (G3-NET) with a Ki-67 index >20%; WHO 2010.

Aim(s): We wished to examine as to whether NEC and G3-NET are considered differently.

Materials and methods: An electronic survey of 39 questions on NEC and G3-NET was constructed on physician practices about characteristics, diagnosis and therapy. Sent to KN members from 23 centres with an interest in NEN (20 centers responded).
