Abstract EN
Background.
Since gastrointestinal stromal tumor (GIST) is a mesenchymal submucosal tumor, the endosonographic, CT, and MRI features of gastric GISTs have been widely investigated.
However, the GIST-bearing gastric mucosa status has not been reported.
Objective.
To characterize the GIST-bearing gastric mucosa status in terms of the degree of inflammation and atrophy, assessed endoscopically.
Subjects and Methods.
The subjects were 46 patients with submucosal tumors (histologically proven gastric GISTs) who had undergone upper gastrointestinal endoscopy in our hospital between April 2007 and September 2012.
They were retrospectively evaluated regarding clinicopathological features, the endoscopically determined status of the entire gastric mucosa (presence or absence and degree of atrophy), presence or absence and severity of endoscopic gastritis/atrophy (A-B classification) at the GIST site, and presence or absence of H.
pylori infection.
Results.
Twenty-three patients had no mucosal atrophy, but 17 and 6 had closed- and open-type atrophy, respectively.
Twenty-six, 5, 12, 1, 1, and 1 patients had grades B0, B1, B2, B3, A0, and A1 gastritis/atrophy at the lesion site, respectively, with no grade A2 gastritis/atrophy.
Conclusion.
The results suggest that gastric GISTs tend to arise in the stomach wall with H.
pylori-negative, nonatrophic mucosa or H.
pylori-positive, mildly atrophic mucosa.
