Ki67 Is Able to Predict Pancreatic NENs Prognosis Irrespective of Their Size

#1753

Introduction: In pancreatic neuroendocrine neoplasms (pNENs), size <20mm and Ki67≤2% suggest indolent behavior. None of these factors alone predicts prognosis. No other predictive factors have been suggested.

Aim(s): We investigated factors predictive of progression in 80 pNEN patients (pts) surgically treated from 1994 to 2014.

Materials and methods: 76 pts had Ki67 <20%; 45 had no liver metastasis (Ki67 ≤2%, n=24; Ki67 2-20%, n=21).
