View clinical trials related to Gastrointestinal Stromal Tumor.
Filter by:Gastric stromal tumor is a gastrointestinal mesenchymal tumor with malignant differentiation potential, the incidence increased year by year. The surgical resection is the primary treatment for it. Although laparoscopic GIST resection has many benefits，due to in lack of the delicate sense of touch, it could lead to the incomplete resection and disorders of digestion. More than 33% of postoperative patients have the gastric dysfunction. Laparoscopic endoscopy combined surgery is different from the past technology. It is a new radical resection of GIST presented by Japanese scholars. LECS resects the tumor completely by laparoscopy with the help of the precise positioning and guidance of endoscopy .This method conforms to the idea of the modern minimally invasive surgery, and avoids many problems，such as incomplete resection and disorders of digestion caused by excessive tissue resection. our team will spearhead the GIST treatment of LECS. First of all, the investigators will collect 120 cases of GIST patients, randomly assigned for the laparoscopic group, the LECS, single-arch the LECS surgical treatment. Secondly, to analyzing the basic treatment and follow-up data, including the operation time, blood loss, the number of transfer laparotomy, the number of cut edge positive, the distances of cut edge away from the tumor edge, the cases of anastomotic fistula bleeding, stenosis, average such confinement, the meal time, cost of treatment, tumor recurrence rate, the presence of residual stomach, upset stomach and frequency, reflux esophagitis, bile reflux gastritis and other indicators.The purpose of this subject is to observe the effectivity and safety of LECS and single-arch the LECS, invent serval LECS equipment patents and provide some references for LECS applying to the minimally invasive surgery of the digestive tract tumor and multidisciplinary treatment mode .
This observational study is proposed to evaluate if the trend in the levels of cf-DNA evaluated on a sample of peripheral blood may be related to different clinical behaviors of the disease monitored by radiological investigations conducted.
The purpose of this study is to evaluate the short-term effect of sealant-assisted skin closure in prevention of surgical site infection after laparoscopic surgery.
Evaluate the reliability of morphology standards for GIST pathologic type, staging and grading by retrospective analyzing clinical data; on this basis, establish a GIST standardized and individualized treatment mode to maximum benefit GIST patients, avoid under- and over-treatment.
The purpose of this study is to determine the efficacy and safety of endoscopic submucosal tunnel dissection (ESTD) compared with video-assisted thoracoscopic surgery (VATS) in the treatment of upper gastrointestinal submucosal tumors.
A Phase II Study of AUY922, Novel HSP Inhibitor, in Patients with Advanced GIST Failed to or Intolerance of Imatinib and Sunitinib Therapy Primary endpoint: •The primary endpoint of this study is to assess disease control rate (complete response + partial response + stable disease≧4 months) of AUY922 in patients with advanced GIST failed to imatinib and sunitinib Secondary endpoints: - To determinate the objective response rate (ORR, complete response + partial response) - To determinate the time to tumor progression (TTP) - To evaluate the safety and toxicity profiles of AUY922 - To evaluate the pharmacokinetics profile of AUY922 in Taiwan GIST population - To access the pharmacodynamic effect of AUY922 on HSP client proteins in blood and tumor if feasible , i.e. HSP70, in Taiwan GIST population - To access the tissue biomarkers pre-treatment and 4wks post treatment if feasible, i.e. HSP70, c-KIT, PDGFRA mutation, ...etc in Taiwan GIST population Exploratory endpoints: •PET imaging; sSUVmax
Our research of the biology of upper gastrointestinal cancers involves the study of tissue samples and cells from biopsies of persons with gastric or esophageal cancer or blood samples from upper gastrointestinal cancer patients and persons at high inherited risk for these cancers. We hope to learn the role genes and proteins play in the development of gastric and esophageal cancer.
To develop new methods to detect malignant and premalignant conditions of the gastrointestinal tract.
The purpose of this study is to determine if and how often an unexpected fast increase of disease and complaints shows after stopping the anti-angiogenetic therapy
