Active clinical trials for "Gastrointestinal Stromal Tumors"

Gastro intestinal stromal tumors (GIST) are rare mesenchymal tumors of the gastrointestinal tract characterized by somatic mutations in the gene encoding the KIT or the PDGFR alpha protein1. Treatment of localized forms relies on adequate surgery without tumor spillage and systemic treatment with imatinib according to risk of relapse defined by localization, tumor size and mitotic count, as well as mutational status. Advanced and relapsing forms are currently treated with oral tyrosine-kinase inhibitors (TKI) of KIT and PDGFR such as Imatinib, Sunitinib and Regorafenib. Over two decades significant changes in drug discovery have impacted treatment strategies, notably via patient's access to various clinical trials. The use of focal treatments such as surgery or interventional radiology with mini invasive procedure of oligometastasis is also being proposed in some cases. There is no precise data on patterns of sequential treatments used, especially proportions of patients with metastatic GIST eventually benefiting from access to a clinical trial or a focal treatment strategy in the course of their disease, and their results in terms of survival on a real life national level. Using the French sarcoma Group national database we aim at describing treatments strategies proposed patients with metastatic GIST in the real life setting. Objectives include : (i) Description of clinico-biological profiles, patterns of care and modalities of treatment of patients with metastatic GIST in a real-life national setting and (ii) evaluation of impact of each treatment line on patients outcome in terms of time to next treatment (TNT) and survival

Liver Transplantation for Unresectable GIST Liver Metastases

This is a longitudinal, multi-center, registry study, collecting data via a web-based portal in patients with GIST (Gastrointestinal Stromal Tumor) from hospitals in Taiwan.

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 purpose of this study is to evaluate the efficacy and safety of rivoceranib and paclitaxel combination therapy in patients with P-glycoprotein overexpressing GIST who failed standard treatment with imatinib, sunitinib, and regorafenib.

This is a prospective, multicenter, observational real-world study to explore the second-line Pharmacotherapy patterns and clinical outcomes in GIST patients who progressed on or were intolerant to first-line anticancer treatment.

So far, MRD assessment by liquid biopsy (ctDNA) has not been used to predict postoperative treatment efficacy and recurrence risk of GIST patients because of special disease characteristics and technological limitations. Therefore, we conducted this prospective multi-center, single-arm observational study to collect 45 operable patients with locally advanced, suspected high-risk GIST. NGS genetic testing platform is used to detect tumour tissues and peripheral ctDNA will also be dectected. we try to explore the correlation between PFS/OS and MRD in high-risk GIST patients by analyzing the relationship between dynamic changes in ctDNA mutation spectrum and postoperative adjuvant therapy efficacy, and to evaluate MRD-based genomic characteristics to guide further treatment.

The goal of this clinical trial is to investigate the efficacy and safety of temozolomide in SDH deficiency GIST patients.

This pilot research trial studies the long term effects of tyrosine kinase inhibitor therapy on ovarian reserve and fertility in patients with chronic myeloid leukemia or gastrointestinal stromal tumor. Studying ovary imaging, ovarian reserve markers, and hormone levels from patients receiving tyrosine kinase inhibitor therapy may help doctors learn more about the effects of tyrosine kinase inhibitor therapy on ovarian function and fertility.

Prior to the implementation of preoperative imatinib mesylate therapy, a considerable percentage (ranging from 34.5% to 67.5%) of individuals diagnosed with rectal gastrointestinal stromal tumors (GIST) underwent abdominoperineal resection (APR), a surgical procedure that involved the removal of the anus and necessitated a permanent colostomy. This study aims to investigate the safety and viability of an organ-preserving approach involving preoperative imatinib mesylate treatment in conjunction with local resection for rectal GIST, specifically targeting patients with c-KIT gene mutations.
