#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.
