Active clinical trials for "Gastrointestinal Stromal Tumors"

The goal of this clinical research study is to learn if Tasigna® (nilotinib) can cause tumor cells to shrink and/or die in patients with GIST who are scheduled for surgery or may be eligible for surgery. The safety of this drug will be studied. Researchers also want to use imaging scans to study the changes in tumor size that may be caused by using nilotinib.

The drug that you are taking for your cancer, imatinib (GleevecTM), has recently been shown to have some new types of side effects. In some people, imatinib can affect how bones are made. The purpose of this study is to find out if imatinib is causing these side effects in you. We can check how your bones form by testing your blood and urine. We can also check your bone strength by doing a special X-ray of your bone called bone density (or DEXA scan).

This study evaluates the combination of trametinib and pazopanib in patients with advanced gastrointestinal stromal tumors (GIST).

The objective of this study is to determine the recommended dose of combination of dovitinib and imatinib in phase I study.

RATIONALE: The use of endoscopy to place a metal stent in the large intestine is less invasive than surgery for treating cancer-related bowel obstruction and may have fewer side effects and improve recovery. PURPOSE: Phase I/II trial to study the effectiveness of endoscopic placement of a metal stent in treating patients who have cancer-related bowel obstruction.

The objective of this study is to evaluate the effect of a perioperative nutrition strategy using oral nutritional supplements (ONS) on postoperative complications and improvement in body weight in malnourished patients who underwent gastrectomy.

Targeted therapies such as multi-targeted tyrosine kinase inhibitors (TKI) and mammalian target of rapamycin inhibitors (mTORI) in renal cell carcinoma (RCC), demonstrate a high level of efficacy with acceptable tolerability. Currently, there are five approved targeted therapies available for RCC: sunitinib (Sutent®), sorafenib (Nexavar®), pazopanib (Votrient®), temsirolimus (Torisel®), and everolimus (Afinitor®). Hepatocellular carcinoma treated with sorafenib and gastro intestinal stromal tumors patients treated with sunitinib will be included, too. Since this agents have dermatological adverse events in common, with oral mucositis (OM), hand-foot skin reaction (HFSR) and papulopustular eruption (PPE) as an disabling side effect, we require evidence based management options to prevent and treat these adverse events. The incidence of OM of any grade is for sunitinib 38%, sorafenib 28%, pazopanib 4%, temsirolimus 41%, and everolimus 44%. Recent data suggest that TKI and mTORI associated OM is distinct from conventional mucositis and more closely resembles aphthous OM. Recently, supersaturated calcium-phosphate rinse (Caphosol®), a Ca2+/PO43- mouth rinse, became available to prevent or treat OM. The objective is to assess the relieving effect of Caphosol® oral rinse on clinical outcomes which include oral intake, swallowing function and pain associated with incidence of grade ≥ 1 oral side effects and the anticancer therapy cessation in patients treated with selected targeted anticancer therapy. Patients with OM > grade 0 on targeted therapy will be randomly allocated to receive either Caphosol® or NaCl 0.9% rinse for two weeks. After the first rinse period all patients will switch to the opposite treatment arm (NaCl 0.9% or Caphosol®) for another two weeks. Duration of oral side effects, severity, pain, dose of analgesics and tolerability will be assessed weekly with the Modified-VHNSS-version-2.0 oral-specific questionnaire. Patients will be stratified by targeted anticancer agent and per tumor type (pre-defined cohorts). Objective severity of oral side effects will be assessed using the NCI-CTCAE v4.0. Correlation of subjective Modified-VHNSS-version-2.0 scores with the objective NCI-CTCAE grade, sex, age, targeted therapy type, and cancer type will be conducted.

RATIONALE: Palliative therapy with octreotide may help patients who have bowel obstruction that cannot be removed by surgery to live longer and more comfortably. PURPOSE: Phase II trial to study the effectiveness of octreotide as palliative therapy in treating patients who have cancer-related bowel obstruction that cannot be removed by surgery.

RATIONALE: The use of endoscopy to place metal stents in the duodenum is less invasive than surgery for treating cancer-related duodenal obstruction and may have fewer side effects and improve recovery. PURPOSE: Phase I/II trial to study the effectiveness of endoscopic placement of metal stents in treating patients who have cancer-related obstruction of the duodenum.

Data are currently insufficient to guide the management of very small gastrointestinal stromal tumors（GISTs）（< 2 cm) discovered incidentally on endoscopy,this study is designed to collect the medical records of patients in different treatment group with long-term follow-up data,and attempts to evaluate the usefulness of regular endoscopic ultrasound（EUS）surveillance and the necessity,safety and feasibility of endoscopic submucosal dissection（ESD）for small GISTs,thus provide evidence for the revision of the guideline.
