AIM To evaluate the efficacy of doubling time (DT) of gastrointestinal submucosal tumors (GIST). METHODS From April 1987 through November 2012, a total of 323 patients were given a final histopathological diagnosis of GISTs on surgical resection or endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in Kitasato University East Hospital or Kitasato University Hospital. We studied 53 ...

introduction: numerous studies have investigated the prevalence, incidence and clinical manifestations of gastrointestinal stromal tumors (gists). however, little is known about gists in iran. this pioneer study focuses on description of 36 patients with gists in iran. methods: a database was created for 36 patients suffering from gist who were treated in loghman medical center and tehran cance...

KIT and / or PDGFRA activation mutation is the initial molecular event of gastrointestinal stromal tumor (GIST), mechanism leading to malignant progression GIST needs be further studied broken through. This study aims understand from perspective metabolic reprogramming provide a new target for treatment GIST. In present study, transcriptome metabolome were used test tissue adjacent normal sampl...

introduction: gastrointestinal stromal tumors (gists) are the most common mesenchymal neoplasms of the gastrointestinal tract. gist has been shown to over-express c-kit (cd117), the receptor tyrosine kinase. imatinib (sti571 or glivec) is a new type of tyrosine kinase inhibitor that selectively inhibits various tyrosine kinases and has been successfully used to treat gist. in this study we have...

Gastrointestinal stromal tumours (GIST) are rare tumours arising from mesenchyme of gastrointestinal tract and overexpress C-kit protein. Mainly seen in stomach and small bowel. Mesenteric GIST are rarely reported as they constitute less than 1% of total GIST. We here report such a rare case of GIST arising from mesentery of small bowel and presenting as acute abdomen. Good surgical clearance e...

Background/Aim: Gastrointestinal stromal tumor (GIST) has a wide spectrum of clinical manifestations. Involvement the groin region can cause interesting presentations but, as 2020, rarely been investigated. Our aim was to assess clinicopathological and prognostic features GIST appearing in this specific part body. Materials Methods: We investigated world literature dealing with primary or metas...

Carney-Stratakis syndrome, an inherited condition predisposing affected individuals to gastrointestinal stromal tumor (GIST) and paraganglioma, is caused by germline mutations in succinate dehydrogenase (SDH) subunits B, C, or D, leading to dysfunction of complex II of the electron transport chain. We evaluated the role of defective cellular respiration in sporadic GIST lacking mutations in KIT...

The Generalizability Index for Study Traits (GIST) has been proposed recently for assessing the population representativeness of a set of related clinical trials using eligibility features (e.g., age or BMI), one each time. However, GIST has not yet been evaluated. To bridge this knowledge gap, this paper reports a simulation-based validation study for GIST. Using the National Health and Nutrit...

BACKGROUND The clinical outcome of gastrointestinal stromal tumor (GIST) has been improved by the introduction of molecular-targeting drugs. However, resistance to these drugs appears during the course of treatment. The aim of this study was to establish and characterize a human xenograft model of GIST. MATERIALS AND METHODS GIST tissue from a patient with esophageal GIST was implanted under ...
