TY - JOUR AU - Wong, Hannah H. AU - Chu, Peiguo PY - 2012 TI - Immunohistochemical features of the gastrointestinal tract tumors JF - Journal of Gastrointestinal Oncology; Vol 3, No 3 (September 01, 2012): Journal of Gastrointestinal Oncology (Current Topics in Gastrointestinal and Liver Pathology) Y2 - 2012 KW - N2 - Gastrointestinal tract tumors include a wide variety of vastly different tumors and on a whole are one of the most common malignancies in western countries. These tumors often present at late stages as distant metastases which are then biopsied and may be difficult to differentiate without the aid of immunohistochemical stains. With the exception of pancreatic and biliary tumors where there are no distinct immunohistochemical patterns, most gastrointestinal tumors can be differentiated by their unique immunohistochemical profile. As the size of biopsies decrease, the role of immunohistochemical stains will become even more important in determining the origin and differentiation of gastrointestinal tract tumors.
