Filter by:This trial is a prospective, randomized (1:1 ratio), multicenter, comparative and phase II study, conducted in patients with unresectable advanced gastrointestinal stromal tumors (GIST) after failure of imatinib (disease progression),sunitinib and regorafenib (either disease progression or intolerance) In the first arm, patients will be treated with imatinib + atezolizumab (experimental arm), whereas in the second arm, patients will be treated with imatinib alone (control arm). The comparison between this two arms will allow to compare whether or not atezolizumab and imatinib is efficient for disease control, in terms of Progression-Free Survival improvement.
To explore the efficacy and safety of preoperative treatment of potentially resectable locally advanced or recurrent metastatic gastrointestinal stromal tumor (GIST) after failure of treatment.
This clinical trial studies if enhanced outpatient symptom management with telemedicine and remote monitoring can help reduce acute care visit due to chemotherapy-related adverse events. Receiving telemedicine and remote monitoring may help patients have better outcomes (such as fewer avoidable emergency room visits and hospitalizations, better quality of life, fewer symptoms, and fewer treatment delays) than patients who receive usual care.
This is a 2 arms study concerning patients under imatinib treatment for at least 10 years of treatment with locally advanced/metastatic GIST. In the first arm, patients will discontinue Imatinib treatment. This arm will allow to determine if the re-introduction of Imatinib at relapse is still an efficient treatment for the control of disease. In the second arm, patients will continue Imatinib treatment, allowing to determine if the continuation of this treatment is efficient for disease control, by the rate of non-progression disease.
This is an open-label positron emission tomography/computed tomography (PET/CT) study to investigate the diagnostic performance and evaluation efficacy of 68Ga-NOTA-RM26 in Gastrointestinal stromal tumor（GIST）patients. A single dose of 55.5 to 148 MBq(1.5-4 mCi) of 68Ga-NOTA-RM26 will be injected intravenously. Patients underwent whole-body PET/CT scans at 30-90 minutes after intravenous injection.
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.
This is a study to evaluate the efficacy and safety of belzutifan monotherapy in participants with advanced pheochromocytoma/paraganglioma (PPGL), pancreatic neuroendocrine tumor (pNET), von Hippel-Lindau (VHL) Disease-Associated Tumors, Advanced Gastrointestinal Stromal Tumor (wt GIST), or Advanced Solid Tumors With hypoxia inducible factor-2 alpha (HIF-2α) related genetic alterations. The primary objective of the study is to evaluate the objective response rate (ORR) of belzutifan per Response Evaluation Criteria in Solid Tumors Version 1.1 (RECIST 1.1) by blinded independent central review (BICR).
Cognitive-behavioral therapy (CBT) has been found to be efficacious in the treatment of cancer-related cognitive impairment (CRCI). Memory and Attention Adaptation Training (MAAT) has been evaluated in previous clinical trials with samples of breast cancer survivors and found effective at reducing cancer-related cognitive impairment. MAAT has been demonstrated to be efficacious when it is delivered via videoconference.The use of telehealth delivery enhances access to cancer survivorship care and reduces time and travel burden among cancer survivors, especially those who live in rural and/or underserved areas where cancer survivor services are less available. People with a diagnosis of gastrointestinal stromal tumors also experience self-reported cancer-related cognitive impairment. In order to determine if MAAT can sufficiently treat CRCI among people with gastrointestinal stromal tumors (GIST), we propose a trial of MAAT to determine its initial level of effectiveness in improving both self-reported cognitive impairments and objective neuropsychological test performance in GIST patients.
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.
This a prospective real-world navigation study using tumor DNA sequencing technology to sequence genes of previously treated and refractory gastrointestinal tumors, which are generally considered to be highly heterogeneous and complex, to screen potential molecular targeted drugs for individualized treatment. This study may provide feasibility and response information, which will be the basis for designing better randomized trials, which may change the pattern of cancer treatment. If the hypothesis is finally proved, it will help doctors and molecular biologists to choose the best drug (or combination of drugs) based on the individual oncogenomics of each patient.
