#175 The Immunohistochemical (IHC) Expression and Prognostic Value of ER, PR, and HER2/neu in Pancreatic and Small Intestinal Neuroendocrine Tumors

Introduction: There has been limited study of ER and PR expression in gastrointestinal neuroendocrine tumors (GINETs) and data on HER2/neu overexpression in GINETS has been conflicting.

#174 Loss of Expression of the DNA Mismatch Repair Proteins MLH1 and MSH2 is Rare in Pancreatic and Small Intestinal Neuroendocrine Tumors

Introduction: Loss of expression of the DNA mismatch repair (MMR) proteins MLH1 and MSH2, which is known to correlate strongly with MSI, has not been well studied in pancreatic or small intestinal NETs.
