| 目的 探讨螺旋CT对胃间质瘤的诊断价值。方法 回顾性分析胃间质瘤43例,所有病例分别行CT平扫及三期增强扫描。所有病例均经病理免疫组化证实,如CD117,CD34,SMA-100及DESMIN。结果 GST的大小、形态和均匀与不均匀的强化方式同恶性程度相关(P＜0.05),与生长方式不相关(P＞0.05); 对比分析表明,病理为恶性、高度恶性及5年内复发、转移的CT征象大多表现为＞5 cm、不均匀强化、腔内/外生长; 17例既向腔内生长又向腔外生长的胃间质瘤患者中,16例病理证实为恶性,有5例在3年内出现复发;5例GST呈间隔状强化,病理结果均为恶性,2例在3年内复发。结论 瘤体直径大于5 cm、不均匀强化、腔内/外生长和浸润与转移提示GST预后不良。 |

| Objective To evaluate the value of spiral CT in diagnosing gastric stromal tumors (GST). Methods Both plain and enhanced CT findings in 43 patients with GST were retrospectively analyzed. In all patients, diagnosis was performed with immunohistochemical markers such as CD117, CD34, SMA-100 and desmin. Results The benign or malignant GST closely correlated with the CT features, such as the tumor size, shape and homogeneous or non-homogeneous enhancement (P＜0.05), but not with growth pattern (P＞0.05); When the CT findings showed the tumor size larger than 5 cm, non-homogeneous enhancement, intra-and extra-luminal growth and infiltrating the organs close to it, the number of the cases that were malignant, high malignant, recurrence and metachoresis was overly high; Of the 17 intra-extra-luminal growth patients, 16 cases were confirmed malignant, 5 cases recurred in 3 years; CT findings of the 5 cases displayed septal enhancement, pathological Results of malignance were confirmed, 2 cases recurred in 3 years. Conclusion The tumor size larger than 5 cm in diameter, non-homogeneous enhancement, intra-and extra-luminal growth and infiltrating its close organs hint the poor prognosis of GST. |
