Trial summary
Introduction: Gastrointestinal Stromal Tumors (GISTs) located in the jejunum or ileum (JI-GIST) are considered of worse prognosis compared to other locations. It has been suggested that this dogma should be revised. Read more about this study

- Adult, Older adult
Study population: GIST diagnosis was established by an experienced board-certified pathologist who reviewed our database prospectively maintained. After revision, we included in the study any kind of primary mesenchymal tumor of the gastrointestinal tract with a histomorphological and immunohistochemical (CD117 (+) and/or DOG1 (+)) profile consistent with GIST. The patients were divided into two groups: patients with GISTs located in the jejunum or ileum, comprising the JI-GIST group; and patients with gastric GISTs, comprising the G-GIST group.
Who may be able to join
- Any kind of primary mesenchymal tumor of the gastrointestinal tract with a histomorphological and immunohistochemical (CD117 (+) and/or DOG1 (+)) profile consistent with GIST.

About this study
Official title: Characteristics and Prognosis of Jejunoileal Gastrointestinal Stromal Tumors (GISTs) in the Era of Imatinib. A Comparative Retrospective Study With Gastric GISTs.
Introduction: Gastrointestinal Stromal Tumors (GISTs) located in the jejunum or ileum (JI-GIST) are considered of worse prognosis compared to other locations. It has been suggested that this dogma should be revised. The aim of this study is to describe the characteristics of jejunoileal GISTs and its prognosis; and to compare them with gastric GISTs in the era of imatinib.
Patients and methods: We retrospectively reviewed the clinical histories of all the patients diagnosed with GISTs between January 2000 and November 2016. Clinical and pathological data, as well recurrence, metastatic, disease-free survival (DFS) as overall (OS) rates of patients with JI-GIST or gastric GIST (G-GIST) were collected and compared.

Questions about this trial
What is this clinical trial studying?
An observational study of Disease-free Survival and Overall Survival, run by Hospital Universitario Virgen de la Arrixaca at 1 site in Spain.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 22 Apr 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Spain. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
KIT Gene mutation (time frame: 15 years). The study lists 7 primary outcomes in all. It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 22 Apr 2019; AzTrials last refreshed its copy on 8 Nov 2026.
