Pathological Factors Predicting Recurrence of the Non-Functioning Pancreatic NET after Resection

#1071

Introduction: The usefulness of the WHO 2010 classification for surgeons has not been elucidated, since the criteria is defined by cell growth with Ki67 and may not represent invasiveness of the tumor as well as the recurrence type (liver metastasis or lymph node metastasis)

Aim(s): The purpose of the study is to elucidate if the WHO 2010 classification is appropriate for the estimation of the tumor malignancy and is applicable to the estimation of recurrence after tumor resection especially for nonfunctioning NET

Materials and methods: From January 2000 to June 2013, we had 98 pancreatic NET patients who underwent resection without distant metastasis. We analyzed 41 non-functioning PNET patients for WHO 2010 classification and other pathological factors with survivals and recurrent locus.
