    Abstract:
    BACKGROUND: A retrospective review on 21 patients with gastric stromal tumors who underwent surgical treatment in the period 1974-2001, is presented. METHODS: The patients were 8 males and 13 females, with an average age of 62.6 years. Histological examination showed 15 smooth muscle tumors (9 benign and 6 malignant), 5 neural tumours (3 benign and 2 malignant) and 1 undifferentiated tumor. Main symptoms were abdominal pain and palpable abdominal mass and the most sensible diagnostic techniques were endoscopy and abdominal CT-scan. Surgical procedures performed were: local resection (15 cases), partial gastric resection (3 cases), subtotal gastrectomy (2 cases) and total gastrectomy (1 case). RESULTS: There were no operative mortality and morbidity. Among 12 patients with benign GSTs, 1 died for causes not related to the disease, while 11 patients are still alive and in good health after a mean follow-up of 148.5 months (range 6-262). Among patients with malignant muscular GSTs, 3 were lost to follow-up and 3 are alive and free from disease after a median follow-up of 58 months (range 3-108). The 2 patients with malignant neural GSTs are still alive and in good health 140 and 24 months after surgical procedure, while the patient with undifferentiated GST died for liver metastases 43 months after total gastrectomy. CONCLUSIONS: The authors conclude that the most frequent symptoms are abdominal pain and a palpable mass, but no specific signs have been detected. Endoscopy plays a very important diagnostic role and CT-scan is the most sensible technique in the evaluation of location, size, invasion of adjacent organs and metastasis. The aim of treatment must be the complete resection of the tumor and the prognostic prediction on the basis of histologic findings is quite difficult.
