#4496 ATRX, DAXX, and menin immunohistochemistry identify prognostic relevant non-functioning neuroendocrine tumours subgroups

Introduction: Non-functioning pancreatic neuroendocrine tumours (NF-pNETs) are rare tumours with a variable prognosis. Recent studies have identified prognostic subgroups based on ATRX, DAXX and MEN1 mutations along with chromosomal aneuploidies.

#4281 Automated (artificial intelligence) vs. manual evaluation of the somatostatin-receptor 2A and proliferation marker Ki-67 in neuroendocrine neoplasms: A pilot study

Introduction: Digital image analysis methods are currently being equipped with artificial intelligence (AI). Various AI applications are already in use to determine Ki-67. To date, there is no specialised AI application available to determine the somatostatin-receptor 2A (SSTR2A).

#3896 Diagnostic utility of menin immunohistochemistry in MEN1 syndrome patients

Introduction: A clinical diagnosis of Multiple Neoplasia type 1 (MEN1) syndrome is confirmed with genetic testing. It is expected that menin protein expression is lost in MEN1 related tumors.
