Filter by:Background: -Some people with wild-type gastrointestinal stromal tumors (WT-GIST) have a deficiency in one of their proteins called succinate dehydrogenase (SDH). Vandetanib is a cancer drug that has been approved to treat thyroid cancer and has been used with some success in other tumors that have a similar loss of SDH. Researchers want to see if this drug can also decrease tumor growth in people with WT-GIST. Objectives: -To test whether the study drug will benefit people with WT-GIST. Eligibility: -Adults and children 3 years old and older with WT-GIST. Design: - Researchers will test participants tumor tissue to confirm it is the wild type of GIST. - Participants will be screened with a medical history, physical exam, and blood tests. They will also have electrical recording of the heart (Eastern Cooperative Oncology Group (ECOG)) and scans of the tumor. - Participants will take the study drug in 28-day cycles. Their doctor will decide how many cycles they can complete. - They will take the study drug once every day and record it in a diary. - On Day 14, they will also visit their doctor to look for side effects. - Before cycles 2, 3 and 4, participants will have a physical exam, urine tests, blood pressure check, and blood tests. These tests will then be done periodically for as long as they are in the study. - Before cycle 4, scans will be done to check the size of the cancer. Most of these will be repeated every 3-6 cycles. - When they stop taking the study drug, participants will return to the clinic for a physical exam and blood tests.
The iCaRe2 is a multi-institutional resource created and maintained by the Fred & Pamela Buffett Cancer Center to collect and manage standardized, multi-dimensional, longitudinal data and biospecimens on consented adult cancer patients, high-risk individuals, and normal controls. The distinct characteristic of the iCaRe2 is its geographical coverage, with a significant percentage of small and rural hospitals and cancer centers. The iCaRe2 advances comprehensive studies of risk factors of cancer development and progression and enables the design of novel strategies for prevention, screening, early detection and personalized treatment of cancer. Centers with expertise in cancer epidemiology, genetics, biology, early detection, and patient care can collaborate by using the iCaRe2 as a platform for cohort and population studies.
The objective is to compare the efficacy and safety of masitinib at 4.5 mg/kg/day to placebo in the treatment of patients with localized, primary gastrointestinal stromal tumor (GIST) after complete surgery and with high risk of recurrence.
The purpose of this study is to evaluate the effects, good and/or bad, of MEK162 and imatinib on the patient and on Gastrointestinal Stromal Tumor (GIST). Funding Source - FDA OOPD, Array/Pfizer
The objective of this study is to assess safety and effectiveness of Regorafenib using in real clinical practice
The treatment of advanced GIST patients is based on imatinib followed with sunitinib in case of resistance/intolerance. However, the median progression-free survival (PFS) on sunitinib is frequently short, and after failure with both imatinib and sunitinib, treatment remains controversial. Previous studies on GISTs have linked 9p21 alterations to tumor progression (El-Rifai et al. 2000; Kim et al., 2000; Schneider-Stock et al., 2003; Schneider-Stock et al., 2005; Romeo et al. 2009; Haller et al., 2008) but the driver gene was not positively identified (CDKN2A, CDKN2B, or MTAP) (Astolfi et al., 2010; Belinsky et al., 2009; Perrone et al., 2005; Assamaki et al. 2007; Huang et al., 2009). A recent study has shown that homozygous 9p21 deletions target CDKN2A and more specifically p16INK4a 4. Most of the CINSARC genes are known to be under the transcriptional control of E2F. RB1 sequesters E2F, which is released from the complex upon RB1 phosphorylation by CDK4. CDK4 is, in turn, inhibited by p16INK4a. Hence, we hypothesize that alteration of the restriction point via deletion of p16INK4a (and more rarely of RB1: 20% of cases) gene in GISTs is likely to be a causative event that leads to the overexpression of CINSARC genes, which in turn induce chromosome instability and ultimately metastasis. Low p16INK4a expression was associated with response to PD-0332991 in several in vitro tumor model(Konecny et al. 2011; Katsumi et al. 2011; Finn et al. 2009). Considering our molecular data, we believed that PD-0332991 warrants clinical investigation in advanced gastrointestinal stromal tumors with alteration of p16INK4a. This alteration is detectable by comparative genomic hybridization which is a technique highly manageable in the context of routine clinical care and clinical trial. Main objective was to assess the antitumor activity of PD-0332991 in terms of non-progression at 16 weeks (after centralized review) in patients with documented disease progression while on therapy with imatinib and sunitinib for unresectable and/or metastatic GIST.
The purpose of this study is to evaluate the efficacy and safety of ponatinib in participants with metastatic and/or unresectable gastrointestinal stromal tumor (GIST) following failure of prior tyrosine kinase inhibitor (TKI) therapy.
Gastrointestinal stromal tumors (GISTs) are a form of sarcoma and the most common sarcoma tumors of the gastrointestinal tract. The limited clinical experience suggests that GIST patients may benefit from neo-adjuvant therapy from primary GIST. This is a prospective, multicenter, open, observational study in evaluation of safety and efficacy of imatinib compared with that of historical data for locally unresectable advanced GIST without metastasis. The study will include an up to 28-day screening period, followed by receiving imatinib mesylate (400 mg/day) for at least 6-12 months and followed up for 3 years after surgery.
The purpose of this study is to collect and assess long-term safety of nilotinib in patients who are on nilotinib treatment in a Novartis-sponsored, Oncology CD&MA study and are benefiting from the treatment as judged by the investigator.
Endoscopic ultrasound (EUS) is a well-established tool for the diagnosis and staging of many gastrointestinal conditions, including but not limited to, malignant and pre-malignant neoplasms of the pancreas, esophagus, rectum, and submucosal tumors developing along the gastrointestinal tract. EUS is the most sensitive test for the detection of focal lesions within the pancreas and is the most accurate method for diagnosing pancreas cancer. A biopsy method for tissue sampling via EUS called fine needle aspiration (FNA) was developed that enables a small needle to be passed into the lesion of interest under ultrasound guidance, obtaining cellular material for cytology. EUS-FNA is currently recommended for the diagnosis of cystic and solid mass lesions within and adjacent to the gastrointestinal tract. Yet in certain clinical circumstances, it is more desirable and sometimes necessary to obtain a core tissue biopsy for histology rather than the cellular material for cytology obtained with EUS-FNA. Furthermore, histology may generally increase the diagnostic yield of EUS-FNA compared to cytology. It is with these aims in mind that a new type of needle, the fine needle biopsy (EUS-FNB) device was developed to enable core tissue sampling. Since a comparison of these to methods has yet to be made, the aim of this study is to perform a direct comparison of the sampling adequacy and diagnostic yield of the new EUS-FNB needle with the conventional EUS-FNA needle.
