Clinical, Radiologic and Pathologic Evaluation of Gastrointestinal Stromal Tumors
Abstract :
Objective: Gastrointestinal stromal tumors (GISTs) are the most common nonepithelial tumors of the gastrointestinal tract. GISTs occur anywhere along the gastrointestinal tract. Due to using radiological modalities often, we see the GİSTs more in our daily practice. We use radiologic modalities for not only making the diagnosis, also following the therapy and tumor progressions-relaps.Material and Method: In this study, 23 GISTs whose diagnosis and therapeutic surgical operations were made in our hospital between January 2007-January 2013, were evaluated retrospectively.Results: The ages of the cases ranged between 32 and 76 and the mean age were 58.70±13.67 years. 52.2% of the cases (n=12) were male and 47.8% of them (n=11) were female. 91.3% of the cases (n=21) were located at GIS and 8.7% of the cases (n=2) were located at non-GIS location. 30.4% of the cases (n=7) were metastatic. When the cases were evalulated in terms of their pathologic risk stratification systems, 39.1% of the cases (n=9) were in high risk group, 34.8% of the cases (n=8) were in intermediate risk group, 26.1% of the cases (n= 6) were in low risk group. The maximum diame-ter of the masses was 10.22 cm. 69.1% of the cases (n=13) showed luminal growth pattern and 38.1% (n=8) showed extraluminal growth pattern. 86.9% of the cases (n=20) had smooth borders, 13.1% of the cases (n=3) had irregular-invasive borders.Conclusion: Imaging is important for diagnosis, theraphy and follow -up. Computed tomography is the first choice for the radiologic evaluation. Also ultrasonography (US), magnetic resonance (MRI) and Flor18-deoxy-glucose positron emission tomography (FDG-PET) can be used in some cases.
