The Relation Between GEP-NEN Prognosis Re-Stratification and Ki-67 Variability: From a Single Institution Study

#1397

Introduction: Ki-67 has been identified as a prognostic factor for GEP NEN.The variability of Ki-67 during the disease course has been reported,but there's few about its effects on prognosis.

Aim(s): We sought to study the association between Ki-67 variations and prognosis via survival re-stratification with one institution cohort.

Materials and methods: A total of 225 patients were enrolled in our cohort, We revised the survival classification on Ki-67 index (decision tree), and evaluated the patients with primary and metastasis specimens, compared the survival of Ki-67 variable group and those not (Kaplan –Meier method).
