Prognosis of Stage IV Gastroenteropancreatic Neuroendocrine Tumors (GEP-NET) According to the WHO Classification and the Primary Tumor Location Abstract #1133

Introduction: WHO classification of GEP-NET is used to predict prognosis, yet survival within each grade shows wide variation. We hypothesized that primary tumor location may be partially responsible of this variability.
Aim(s): To evaluate the prognosis of stage IV GEP-NET according to WHO classification and primary tumor location.
Materials and methods: We present a subset analysis from RGETNE (registry of Spanish NET Group (GETNE)). The impact of grade was assessed using Cox regression method. Covariates in the model were chromogranin, primary tumor size/location (gastrointestinal, pancreatic or unknown), functionality, ECOG PS and number of metastatic sites. gastrointestinal and grade 1 tumors were used as references categories.
