#1689 The Prognostic Value of the Expression of Cytokeratin 7 and 19 in Lungs and Pancreas Neuroendocrine Tumors

Introduction: The expression of cytokeratins (CK) 7,19 rarely occurs in the low grade neuroendocrine tumors (NET) of lung and pancreas. It is known that part of the low grade typical (TC) and atypical (ATС) carcinoids of lung and pancreas (pNET-G1,G2) can progress quickly and to metastasize. It is important to distinguish NET with a less differentiated cells immunophentype.

#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.

#419 Morphological Characteristics of Pancreatic Tumors in Children and Young Patients

Introduction: Pancreatic tumors (PT) usually occur after age 60 and almost never in children and young patients (pts). Little is known concerning frequency, morphological and immunohistochemical (IHC) characteristics of PTs in children and young pts.

#417 CK19 Expression in A?TH-Producing Extrapituitary Neuroendocrine Neoplasms is a Negative Prognostic Factor

Introduction: Defining localization and potential ?CTH-producing extrapituitary neuroendocrine neoplasms (ACTH-epNEN) is important for clinical practice.
