#3883 Immune landscape in mixed neuroendocrine-non neuroendocrine neoplasms (MiNEN)

Introduction: A mixed neuroendocrine-non neuroendocrine neoplasm (MiNEN) is a novel defined rare entity, made up of two morphologically distinct neoplastic components; one neuroendocrine type (NEN), and the other one non-neuroendocrine type (nNEN). Neuroendocrine differentiation of tumors is thought to influence the tumor microenvironment (TME) through the secretion of various hormones or growth factors.

#813 Comparison of Manual and Automatic Methods of Ki-67 Proliferation Index for Neuroendocrine Tumors: The Development and Validation of a Novel Digital Pathology Tool (Ki-67Counter)

Introduction: Ki-67 proliferation index is an increasingly important biomarker used to grade neuroendocrine tumors. Manual counting methods are laborious and subject to inter- and intra-observer variability. Digital counting methods hold promise for fast and reproducible indices, however, they are fraught with technical difficulties.
