#4544 Spatial and temporal intratumour heterogeneity of pancreatic neuroendocrine tumours (PanNET)

Introduction: Data derived from the study of intertumour heterogeneity have led to propose that PanNET evolution may start either from beta cells with good prognosis, or from alpha cells with sequential alterations of MDA (MENIN-DAXX/ATRX) leading to more aggressive lesions.

#4079 Temporal increase in Ki-67 index in patients with pancreatic neuroendocrine tumors (PanNETs): Frequency, prognostic impact, and causal factors
