gist cancer

Mark Agulnik, Steven Attia
Sarcomas encompass a group of rare solid tumors responsible for approximately 1% of all cancer-related deaths in the United States each year. Subtypes include, but are not limited to, soft tissue sarcomas (STS) such as leiomyosarcoma, liposarcoma, pleomorphic sarcoma, and gastrointestinal stromal tumor (GIST). Treatment options for patients with STS vary depending on, among other factors, histological subtype. Data from a mix of phase 2 and phase 3 trials have suggested that the orally available multikinase inhibitor regorafenib may have efficacy in patients with STS who have progressed on previous lines of systemic therapy...

BACKGROUND: For cancers of the distal gastroesophageal junction or the proximal stomach, proximal gastrectomy can be performed. It is associated with several perioperative benefits compared with total gastrectomy. The use of laparoscopic proximal gastrectomy (LPG) has become an increasingly popular approach for select tumors. METHODS: We describe our method of LPG, including the preoperative work-up, illustrated depictions of the key steps of the surgery, and our postoperative pathway...

Gastrointestinal stromal tumours (GIST) are the most common mesenchymal tumors of the gastrointestinal (GI) tract. In order to investigate a new treatment fot GIST, we hypothesized the effect of miR-374b targeting PTEN gene-mediated PI3K/Akt signal transduction pathway on proliferation and apoptosis of human gastrointestinal stromal tumor (GIST) cells. We obtained GIST tissues and adjacent normal tissues from 143 patients with GIST to measure the levels of miR- 374b, PTEN, PI3K, Akt, caspase9, Bax, MMP2, MMP9, ki67, PCNA, P53 and cyclinD1...

Radiologists can detect abnormality in mammograms at above-chance levels after a momentary glimpse of an image. The study investigated this instantaneous perception of an abnormality, known as a "gist" response, when 23 radiologists viewed prior mammograms of women that were reported as normal, but later diagnosed with breast cancer at subsequent screening. Five categories of cases were included: current cancer-containing mammograms, current mammograms of the normal breast contralateral to the cancer, prior mammograms of normal cases, prior mammograms with visible cancer signs in a breast from women who were initially reported as normal, but later diagnosed with breast cancer at subsequent screening in the same breast, and prior mammograms without any visible cancer signs from women labelled as initially normal but subsequently diagnosed with cancer...

BACKGROUND AND OBJECTIVES: Prior small studies have reported a possible association between renal cell carcinoma (RCC) and gastrointestinal stromal tumors (GISTs). In the largest known series, our objective was to describe the prevalence of RCC among patients with GISTs over 26 years at Memorial Sloan Kettering Cancer Center (MSKCC). METHODS: We retrospectively reviewed MSKCC's prospectively maintained sarcoma and RCC databases and identified all patients with both RCC and GIST between 1980 and 2016...

BACKGROUND AND AIMS: Gastrointestinal stromal tumors (GISTs) are rare malignancies but the most common mesenchymal tumors of the digestive tract. Recent advances in diagnostic imaging and an increasing incidence will confront us more frequently with stromal tumors. This single center study aimed to characterize GIST patients in terms of tumor location, clinical presentation, metastasis formation, as well as associated secondary malignancies. METHODS: In a retrospective study, 104 patients with a histologically confirmed diagnosis of GIST, collected between 1993 and 2011, were characterized for several clinical features...

We conducted a retrospective cohort study using data compiled from the regional German cancer registries by the Centre for Cancer Registry Data (ZfKD) at the Robert Koch Institut (RKI) to describe the epidemiology of adult soft-tissue sarcomas (STS) in Germany in 2003-2012, focusing on advanced STS. We identified 33,803 incident adult cases of STS (other than the Kaposi sarcoma and gastrointestinal stromal tumors). The incidence of STS was 6.05 (95% confidence interval (CI), 5.82-6.29) per 100,000 in 2012 (4,079 cases)...

Background: Perioperative enteral nutrition (EN) enriched with immune-modulating substrates is preferable for patients undergoing major abdominal cancer surgery. In this study, perioperative EN enriched with immune-modulating nutrients such as arginine, glutamine, and omega-3 fatty acids was evaluated for its anti-inflammatory efficacy in patients with gastric adenocarcinoma or gastrointestinal stromal tumor (GIST) receiving curative surgery. Materials and Methods: This prospective, randomized, double-blind study recruited 34 patients with gastric adenocarcinoma or gastric GIST undergoing elective curative surgery...

PURPOSE: c-KIT overexpression is well-recognized in cancers such as GIST, SCLC, melanoma, NSCLC and AML. Treatment with the small molecule inhibitors imatinib, sunitinib and regorafenib result in resistance (c-KIT mutant tumors) or limited activity (c-KIT wildtype tumors). We selected an anti-c-KIT ADC approach to evaluate the anti-cancer activity in multiple disease models. EXPERIMENTAL DESIGN: A humanized anti-c-KIT antibody LMJ729 was conjugated to the microtubule destabilizing maytansinoid, DM1, via a non-cleavable linker (SMCC)...

Background: Colon and rectal gastrointestinal stromal tumors (GISTs) are rare and poorly characterized. Because the majority of treatment guidelines for GISTs are extrapolated from tumors of gastric and small bowel origin, our aim was to better characterize the unique clinicopathologic features and prognostic factors of colon and rectal GISTs to guide clinical care. Methods: The National Cancer Data Base (NCDB) was queried from 2006 to 2013 for cases of GISTs in the stomach, colon, and rectum...

The introduction of next generation sequencing (NGS) in the routine diagnostic setting is still in the development phase and has been limited by its complexity. Targeted NGS offers an attractive alternative to performing multiple single target assays and is very useful in meeting the increasing clinical demand for testing of multiple genetic aberrations in cancer specimens. To this end, we carried out a blinded validation study on 113 tumours in a diagnostic laboratory and compared mutation results from targeted NGS with those from Sanger sequencing, pyrosequencing, competitive allele specific TaqMan polymerase chain reaction (CAST PCR) and Cobas assays...

Gastro-intestinal tumours (GISTs) are driven by aberrant expression of the c-KIT oncoprotein. They can be effectively treated by the kinase inhibitor imatinib, which locks the c-KIT kinase domain into an inactive conformation. However resistance to imatinib, driven by active-site mutations, is a recurrent clinical challenge, which has been only partly met by the subsequent development of second and third-generation c-KIT inhibitors. It is reported here that a tetra-substituted naphthalene diimide derivative, which is a micromolar inhibitor of cell growth in a wild-type patient-derived GIST cell line, has a sub-micromolar activity in two distinct patient-derived imatinib-resistant cell lines...

The clinical utility of circulating tumor cells (CTCs) has been investigated in numerous publications, but CTCs that express very typical immune cell markers have not been reported. Here we report a novel class of CTCs-CSV-positive macrophage-like CTCs (ML-CTCs). This nomenclature was based on the fact that this class of CTCs can be captured from blood samples of gastrointestinal stromal tumors (GISTs) patients using either the macrophage marker CD68 or our proprietary tumor-specific cell-surface vimentin (CSV) antibody 84-1; likewise, the captured ML-CTCs can be co-stained with both typical macrophage markers (CD14, CD68) and tumor cell markers (DOG-1, C-kit) but not CD45...

Because of the low incidence of nongastrointestinal stromal tumor (non-GIST) spindle cell sarcomas of the colon or rectum, the clinical behavior and ideal surgical treatment of these tumors and patient outcomes are poorly defined. The purpose of this study was to characterize these tumors and to determine the best surgical approach. We identified 1056 patients with non-GIST spindle cell sarcomas of the colon or rectum (1998-2010) in the National Cancer Database and collected data for each patient that included patient and tumor characteristics, tumor site (colon vs rectum), surgery type, and outcomes...

BACKGROUND: The molecular pathogenesis of many forms of soft tissue sarcomas (STS) have been rigorously characterized in the medical literature, which may be particularly important for the diagnosis and prediction of prognosis in STS. METHODS: Electronic databases (2005 to October 2016) were searched. Gastrointestinal stromal tumor and pediatric sarcomas were excluded. The eligible individual study's risk of bias and the quality of aggregate evidence were assessed...

BACKGROUND: Gastrointestinal stromal tumor (GIST) is a rare cancer in gastrointestinal carcinomas and has been widely known as a curable disease among all the digestive tumors. However, early detection of malignant potential in patients with GIST has still been a huge challenge all around the world. CT, MRI, and F-18 FDG PET are all considered as good tests for diagnosing malignant GIST efficiently, but no recommended suggestions presents which test among the 3 is the prior one in detecting the malignant potential of GIST...
