#4404 A comparative study on the progression of neuroendocrine carcinomas and mixed neuroendocrine-non-neuroendocrine neoplasms

Introduction: The prognostic differences between neuroendocrine carcinoma (NEC) and mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) remain unclear.

Keywords: mixed neuroendocrine–non-neuroendocrine neoplasm (MiNEN), neuroendocrine carcinoma (NEC), disease progression, treatment protocol, signalling pathway,

#3921 Mixed neuroendocrine-non-neuroendocrine neoplasms of the rectum: A case report

Introduction: Mixed Neuroendocrine-Non-Neuroendocrine Neoplasms (MiNEN) represent roughly 1-2% of all colorectal malignancies. Given the rareness and heterogeneity of these mixed tumors, recognition and accurate diagnosis remain a challenge. In the absence of established guidelines, they are treated according to the standard of care for pure neuroendocrine carcinomas or adenocarcinomas from similar sites of origin.

#3583 Mixed Neuroendocrine-Non-Neuroendocrine Neoplasms (MiNEN): Characterization of the genomic and pathological profile

Introduction: A mixed 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). As available data are limited, the epidemiology and controversial pathogenesis of MiNENs remain mostly unknown.
