Type 3 Gastric Neuroendocrine Neoplasms: Relationship Between Tumor Size, Ki67 and Clinical Outcome

#1803

Introduction: Sporadic type 3 gNENs are usually malignant with high metastatic potential, mostly large, with a high grade histology. However, little is known on the relationship between tumor size, proliferative index Ki67, and clinical outcome

Aim(s): To evaluate the impact of Ki67 and tumor size on clinical outcome in type 3 gNENs.

Materials and methods: Multi-center retrospective study. Linear regression and receiver operating curve (ROC) were used to perform the prognostic analysis. Values are expressed as median (range).
