Prognostic factors in malignant gastrointestinal stromal tumors.
Gastrointestinal stromal tumors are a heterogeneous group of mesenchymal neoplasms of the gastrointestinal tract in which routine histopathological evaluation fails to reveal definitive evidence of differentiation. Given the heterogeneity in clinical presentation and the frequent morphological overlap, the biological behavior of these neoplasms is difficult to predict. We have evaluated, by Cox...
متن کاملDiagnostic and treatment strategy for small gastrointestinal stromal tumors
Gastrointestinal stromal tumors (GISTs) are considered to be potentially malignant mesenchymal tumors of the gastrointestinal tract. Clinically relevant GISTs are rare; however, subclinical GISTs (mini-GISTs) (1-2 cm) and pathologic GISTs (micro-GISTs) (<1 cm) are frequently reported. Most mini-GISTs and almost all micro-GISTs of the stomach may exhibit benign clinical behavior, and only mini-G...
متن کاملHistological 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 کاملDiagnostic methods for initial evaluation of primary gastrointestinal stromal tumors.
OBJECTIVE To describe the imaging features of gastrointestinal stromal tumors (GISTs) at initial presentation with clinical, surgical, and pathologic correlation, and to evaluate values of various techniques in GISTs. METHODS This retrospective study recruited 70 patients with histologically proved GISTs between December 2004, and May 2009 in the Department of General Surgery, Zhongshan Hospi...
متن کاملThe Diagnostic and Prognostic Utility of DOG1 Expression on Gastrointestinal Stromal Tumors.
OBJECTIVE We aimed to review our archives in order to evaluate both the diagnostic and prognostic significance of DOG1 on gastrointestinal stromal tumors (GISTs), and add further insight about those issues to the current literature including some conflicting results. MATERIAL AND METHOD DOG1 was evaluated in 100 cases of GISTs, immunohistochemically. Immunostaining index was counted for each ...
