Histological and Immunological Evaluation of Gastrointestinal Stromal Tumors
Background: Gastrointestinal stromal tumors (GISTs) constitute the majority of gastrointestinal mesenchymal tumors. They usually express a proto-oncogen protein called CD117 detected by immunohistochemistry. This study investigated the differentiation of GISTs as well as the risk of aggressive behaviors in GISTs from surgically-treated patients in university affiliated hospitals. Methods: The c...
متن کاملConnective tissue growth factor expression in endocrine tumors is associated with high stromal expression of alpha-smooth muscle actin.
OBJECTIVE Complications due to fibrosis development are common in patients with well-differentiated endocrine carcinomas in the small intestine (ileal carcinoids). Connective tissue growth factor (CTGF) expression in ileal carcinoids may be related to this fibrosis development. This study aimed to examine CTGF expression in relation to local myofibroblast differentiation in a large series of il...
متن کاملMaspin expression in gastrointestinal stromal tumors
BACKGROUND To investigate the role of maspin expression in the progression of gastrointestinal stromal tumors, and its value as a prognostic indicator. METHODS In the study 54 patients with GIST diagnosis were included in Uludag University of Faculty of Medicine, Department of Pathology between 1997-2007. The expression of maspin in 54 cases of gastrointestinal stromal tumor was detected by i...
متن کاملColorectal mesenchymal tumors - from smooth muscle tumors to stromal tumors.
Colorectal mesenchymal tumors are rare. Therefore, distinguishing between gastrointestinal stromal (GIST) and smooth muscle tumors is important. This study aimed to delineate the immunophenotype and prognostic factors of 75 colorectal mesenchymal tumors. Fifty-three GIST and 22 smooth muscle tumor specimens were included from 1986 to 2007. Forty of 53 GIST were initially diagnosed as smooth mus...
متن کاملExpression of DOG1, PDGFRA, and p16 in Gastrointestinal Stromal Tumors
BACKGROUND/AIMS The diagnosis of gastrointestinal stromal tumors (GIST) relies on the demonstration of KIT expression, but KIT expression is absent or reduced in approximately 15% of GIST. METHODS Eighty-one GISTs were diagnosed between January 1998 and December 2007 at the Department of Pathology at both Chungnam National University Hospital and Eulji University Hospital, Daejeon. Medical hi...
