螺旋CT分析胃间质瘤的大小与病理及预后的关系

Relationship between tumor size of gastric stromal tumor and its pathology and prognosis

目的:探讨胃间质瘤(GST)的大小与病理及预后的关系。方法:回顾性分析43例GST患者(良性9例,恶性34例)的螺旋CT资料和病理及预后的关系。结果:螺旋CT所示GST的大小同肿瘤的良、恶性及5a内复发、转移有关(P均<0.05);恶性、高度恶性及5a内复发、转移的病例螺旋CT征象大多表现为瘤体直径大于10cm。结论:螺旋CT对分析GST的大小,判断GST良、恶性及预后具有重要价值。

Aim ：To study the relationship between the tumor size of gastric stromal tumors（GST） and its pathology and prognosis. Methods： Spiral CT findings and pathological sections of 43 patients with GST（9 benign cases, and 34 malignant cases） were reviewed and 24 patients were followed up. Relationship between tumor size and outcomes was studied. Results： Tumor size was related with benignity or malignancy, recurrence and metastasis within 5 years. The tumor with diameter 〉 10 cm manifested higher malignancy,recurrence rate and metastatic frequency. Conclusion： Spiral CT is of great value in analyzing the tumor size and evaluating benignity or malignancy and prognosis of GST.
