#3652 Features of the expression of TTF-1 and Cytokeratin 19 as a predictor of a less favourable prognosis of atypical lung carcinoids

Introduction: Atypical lung carcinoids are a highly heterogeneous group of tumors, some of which have more malignant potential, which makes the search for additional morphological prognostic criteria relevant.

#827 Neuroendocrine Tumors of the Pancreas Grade 2 with Ki-67 Index More Than 5% and with Expression Cytokeratin 19 are the Risk Group of Rapid Progression

Introduction: Cytokeratin 19 (CK19) is the marker of pluripotent cells of the epithelium of the pancreatic ducts, which is not detected in differentiated endocrine cells. Our experience shows that many patients with neuroendocrine tumors of the pancreas (pNET) G2 have a rapid progression of the disease a few years after diagnosis, and metastases are found most commonly in the liver.
