Contrast Harmonic Endoscopic Ultrasonography (CH-EUS) is Able to Predict Aggressivity in Pancreatic Neuroendocrine Tumors

#1137

Introduction: Pancreatic neuroendocrine tumors (PNET) are a heterogeneous group regarding malignancy.

Aim(s): To assess the ability of CH-EUS to predict aggressivity in PNET.

Materials and methods: In a monocentric retrospective study, histologically proven PNET were included and classified in two groups: « lowly aggressive » / «highly agressive» tumors corresponding to T3-T4 and/or N+ and/or M+ G1/G2, or G3. Uni- and multivariate analyses were performed to assess factors associated with aggressivity. Sensitivity (Se), Specificity (Sp), Positive Predictive Value (PPV) and Negative Predictive Value (NPV) were calculated.
