title: Endoscopic resection of benign very low-risk gastric gastrointestinal stromal tumors. Is it enough?
abstract: Great ongoing debate still exists over the definition, diagnosis and treatment of gastrointestinal stromal tumour especially for small gastric submucosal tumours. Simple endoscopic biopsy is not sufficient to determine their biological behaviour and their complete excision is necessary. We report the case of a 65-year-old woman, who was kept under observation after previously operated breast cancer, with a casual computed tomography-diagnosed submucosal gastric lesion. Endoscopy and endoscopic ultrasound confirmed a submucosal mass of 2-3 cm in diameter. An endoscopic resection was performed and the mass was integral at pathologic examination. It confirmed the stromal origin with a mitotic index of 1 (5/50 high power field). No more treatment was carried out because it was classified as a very low risk gastrointestinal stromal tumour according to Fletcher's classification. After 34 months follow-up, the patient is disease free and we believe that endoscopic treatment is sufficient and recommended for mainly intragastric growing gastrointestinal stromal tumour with a diameter of less than 3 cm.
