Filter by:This is the first clinical trial of IDRX-42. The study is designed to evaluate the safety, tolerability, PK, and preliminary antitumor activity of IDRX-42 in adult participants with advanced (metastatic and/or surgically unresectable) GIST.
Nowadays, for the selection of the treatment for gastrointestinal stromal tumors (GISTs), tumor size, prognosis, resectability and stage should be considered. Due to mutations in KIT and platelet-derived growth factor alpha (PDGFRA) in 90% of patients with this mesenchymal tumor, many tyrosine kinase inhibitors are used. On the other hand, a resectable tumor is approached by surgery, endoscopic and ablation therapy. Radiofrequency ablation (RFA) approach has been studied in hepatic GISTs, and hepatic metastases, but its evaluation in esophageal, gastric, and intestinal GISTs is scarce. This study aims to determine the feasibility, safety and efficacy of endoscopic ultrasound (EUS) guided RFA using the 19 G RFA probe developed by Taewong Medical for the treatment of GISTs.
The objective of this observational study is to explore the efficacy and safety of ripretinib treatment combined with surgery in advanced gastrointestinal stromal tumors(GIST) after failure of imatinib therapy.
The R0 resection rate of gastrointestinal stromal tumor (GIST) with high recurrence risk was relatively low, and the relapse-free survival rate was relatively low, which needed to be further improved. A few retrospective analyses and a small sample of prospective studies have found that neoadjuvant therapy with imatinib mesylate can improve R0 resection rates. Whether neoadjuvant therapy prolongs long-term survival remains unclear. The primary objective of this study was to evaluate 5-year progression-free survival (PFS) for GIST patients with high recurrence risk after neoadjuvant treatment with imatinib mesylate.
The genetic background for cancer treatment may also be different among different areas and races. There is lack of Taiwanese data of genetic alterations in cancer patients. To understand the landscape of genetic aberrations of cancer in Taiwan, large scale survey of the cancer patients is indicated. In this pilot study, the investigators want to evaluate the landscape of genetic aberrations in cancer patients via oncopaenl test and collect the clinical data of the patients. The result of the oncopanel test will be returned to patient and their attending physician for reference of their further treatment. In addition, the investigators want to correlate the clinical outcome with the genetic aberrations of the cancer patients in Taiwan. Gastrointestinal stromal tumor (GIST) is a rare cancer compared with the other solid tumors. C-KIT or PDGFRA mutation is found in approximately 85-90% of GISTs. Imatinib, a tyrosine kinase inhibitor targeting c-KIT, has been used to treat advanced GIST successfully since 2000. However, resistance to imatinib may develop either via secondary mutation of c-KIT or primary resistance to those with wild type c-KIT and PDGFRA. Although sunitinib and regorafenib have been approved as second and third line of treatment for advanced GIST, the progression free survival were only 6.8 and 4.8 months, respectively. The genetic landscape of GIST with wild type c-KIT and PDGFRA was less studied. In the current study, the investigators want to focus on the GISTs with wild type c-KIT and PDGFRA to perform the NGS oncopanel for these patients. Then the investigators can understand the genetic aberrations of these patients (wild type GIST) and help for searching the potential treatment targets to them.
Objective: To follow people with GISTs and collect tumor tissue so that it can be studied in the lab. Eligibility: People age 6 and older who have a GIST. Design: Participants will be screened with a review of their medical records and samples. Participants will enroll in 1 other NIH study, and may be asked to enroll in 2 other optional NIH studies. Participants will have a medical history and physical exam. Data about how they function in their daily activities will be obtained. Participants may speak with a genetic counselor. They may have genetic testing. Participants will give blood samples. They may have a cheek swab. For this, small brush will be rubbed against the inside of the cheek. Participants may have a computed tomography (CT) scan of the chest, abdomen, and pelvis. Or they may have a CT scan of the chest and magnetic resonance imaging (MRI) of the abdomen and pelvis. Participants will be monitored every 6-12 months at the NIH Clinical Center, for up to 10 years before having surgery. If they need surgery, it will be performed at the NIH. Then, they will be monitored every 6-12 months, for up to 5 years after surgery. If a participant has surgery, tumor tissue samples will be taken. If a participant does not need surgery, their participation will end after 10 years. If they have surgery, the 5-year monitoring period will restart after each surgery.
Gastrointestinal Stromal Tumors (GIST) is the most common mesenchymal tumor of the gastrointestinal tract, and the incidence rate in China has increased year by year in recent years.Gastrointestinal stromal tumors are not sensitive to radiotherapy and traditional infusion chemotherapy. Currently, they are generally treated with surgery, but they are prone to recurrence and metastasis.For nodules with a particle size between 2 and 5 cm, there may be both benign and malignant, and there is still a lack of fast and accurate methods for distinguishing benign and malignant.Many benign nodules were removed (in the pathological examination of postoperative resected tissue). In addition, if it is found to be late, there is a possibility of invading surrounding tissues and metastasis, so that it is impossible to cure. Therefore, early diagnosis and early surgery and benign and malignant differentiation of small nodules are the key to the clinical diagnosis and treatment of gastrointestinal stromal tumors.At present, second-generation gene sequencing (NGS) and liquid biopsy are rarely reported in the field of GIST. A few domestic and foreign studies have found that it can detect rare mutation types, and may find secondary gene mutations early, which has potential applicability, but Overall, the clinical guidance of these NGS-based studies focuses on prognosis and drug resistance , as well as some studies based on low-throughput platforms. Therefore, early diagnosis and benign and malignant discrimination based on high-throughput sequencing and liquid biopsy have significant clinical significance for the diagnosis and treatment of gastrointestinal stromal tumors.
