Active clinical trials for "Gastrointestinal Stromal Tumors"

The study investigates response assessment of gastrointestinal stromal tumors using Dual Energy CT (DECT) in patients undergoing targeted therapy with a TKI Inhibitor.

Some researches have shown surgery may acquire progression-free (PFS) benefit for selected patients with metastatic gastrointestinal stromal tumor (GIST) who received first-line imatinib and second-line sunitinib. However, impact of salvage surgery on pre-treated GIST patients receiving third-line regorafenib facing progression is not yet reported. Investigators retrospectively reviewed patients with regorafenib treatment with salvage surgery.

The BCCA Oncopanel is a clinical assay being developed to determine genotype status of a prospectively defined set of genes. The purpose of this pilot study is to assess the feasibility and effect on clinical-decision-making of the Oncopanel test. Eligible patients are those with advanced lung, colorectal, melanoma and GIST cancers and patients with diagnosed malignancies being considered for clinical trials.

RATIONALE: Studying the genes expressed in samples of tumor tissue from patients with cancer may help doctors identify biomarkers related to cancer. PURPOSE: This research study is looking at tumor samples in patients undergoing treatment for gastrointestinal stromal tumors on clinical trial ACOSOG-Z9001.

The purpose of this trail is to evaluate the performance of Genetron D842V PCR kit in GIST patients using real-time PCR method.

Gastrointestinal stromal tumors (GISTs) are a form of sarcoma and the most common sarcoma tumors of the gastrointestinal tract. The limited clinical experience suggests that GIST patients may benefit from neo-adjuvant therapy from primary GIST. This is a prospective, multicenter, open, observational study in evaluation of safety and efficacy of imatinib compared with that of historical data for locally unresectable advanced GIST without metastasis. The study will include an up to 28-day screening period, followed by receiving imatinib mesylate (400 mg/day) for at least 6-12 months and followed up for 3 years after surgery.

Despite laparoscopic surgical treatment has not been recommended in patients with gastric gastrointestinal stromal tumors (GIST) larger than 5 centimeter, but it continues to evolve rapidly to overcome the boundaries. Therefore the authors generated a morpho-anatomical classification system (MACS) adapted for primary gastric GISTs, by which they could plan to tailor the laparoscopic gastric resection appropriately. The aims of the study was to demonstrate the feasibility of laparoscopic surgery for primary gastric GISTs larger than 5 cm, to find out the accuracy and practicality of the MACS for the development a preoperative strategy and the extent to which this strategy overlaps with the reality.

This is a multi-institutional retrospective study in order to identify the most relevant and advisable features of follow-up, and to explore its impact on principal clinical outcomes. Moreover, a dedicated effort will be pursued to identify the peculiar characteristics (if any) of patients that experienced recurrence of the disease. The study will collect data about patients affected by primary GIST at very-low and low risk of recurrence/progression, referred to participating Institutions between January 2000 and February 2020

To monitor use in real practice including adverse events and efficacy on Sutent capsules (Sunitinib malate)

The objective of this study is to assess safety and effectiveness of Regorafenib using in real clinical practice
