Mixed Neuroendocrine Non-Neuroendocrine Neoplasms of the Gastrointestinal Tract: A Case Series

Healthcare, 2022
Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) refer to heterogenous rare neoplasms constituted of at least a neuroendocrine population—either well-differentiated, or more frequently poorly differentiated—and a non-neuroendocrine population, both accounting for at least 30% of the whole tumor mass.

Mixed Neuroendocrine Non-Neuroendocrine Neoplasms: A Systematic Review of a Controversial and Underestimated Diagnosis [PDF]

Journal of Clinical Medicine, 2020
Mixed neuroendocrine non-neuroendocrine neoplasms (MiNENs) represent a rare diagnosis of the gastro-entero-pancreatic tract. Evidence from the current literature regarding their epidemiology, biology, and management is of variable quality and conflicting.

Mixed neuroendocrine-non-neuroendocrine neoplasm of the colon: case report

Experimental and Clinical Gastroenterology, 2022
Mixed neuroendocrine-non-neuroendocrine neoplasm (MiNEN) is defined as a tumor composed of cells originating from neuroendocrine cells in the embryonic intestine and elements of epithelial adenocarcinoma. To determine the differentiation grade of MiNEN, the proliferation index was used, for which at least 500 cells were examined. MiNEN is a rare neoplasm
