[摘要] 目的 高-中危险度与低-极低危险度组胃间质瘤的影像诊断。 方法 回顾性分析2015年4月—2017年12月期间该院50例经手术病理证实的胃间质瘤患者的CT影像及病理资料,根据危险度不同,分为高-中危险组(24例)与低-极低危险组(26例),观察两组患者是否在CT特征上有差异。 结果 高-中级别组胃间质瘤钙化10例、坏死23例、形态(分叶)18例、最大径>4 cm 20例;低-极低级别组钙化3例、坏死10例、形态(分叶)7例、最大径>4 cm 8例,(P=0.035、0.000、0.001、0.001),高-中级别组溃疡13例、混合生长9例、年龄(56.95±14.22)岁、平扫CT值(31.95±8.57)、动脉期CT值(61.79±20.76)、门静脉期CT值(70.50±19.34);低-极低级别组溃疡11例、混合生长6例、年龄(55.50±11.11)、平扫CT值(34.69±7.44)、动脉期CT值(62.15±21.13)、门静脉期CT值(73.03±26.16),(P=0.402、0.266、0.687、0.237、0.952、0.700,χ2=0.703,1.236,0.406,-1.199,-0.061,-0.387)。结论 高-中危险度与低-极低危险度组胃间质瘤CT影像征象,對胃间质瘤危险度的分级具有重要的参考价值。

[Abstract] Objective To evaluate the imaging of high-to-moderate and low-risk gastric stromal tumors. Methods CT images and pathological data of 50 patients with gastric stromal tumors confirmed by surgery and pathology during April 2015 to December 2017 were retrospectively analyzed. According to the risk, the patients were divided into high-to-moderate risk groups (24 cases) and the low-low risk group (26 cases), whether or not the CT characteristics were different in the two groups was observed. Results High-medium group calcification of gastric stromal tumors in 10 cases, necrosis in 23 cases, morphology (separation) in 18 cases, maximum diameter >4 cm in 20 cases; low-low-grade group calcification in 3 cases, necrosis in 10 cases, morphology (foliar 7 cases, 8 cases with a maximum diameter >4 cm, P=0.035, 0.000, 0.001, 0.001, 13 cases of high-medium group ulcers, mixed growth 9 cases, age (56.95±14.22)years, plain CT value (31.95±8.57), arterial phase CT value(61.79±20.76), portal venous phase CT value (70.50±19.34); low-low-grade group ulceration in 11 cases, mixed growth in 6 cases, age(55.50±11.11), plain CT value (34.69±7.44), arterial phase CT value was (62.15±21.13), and the portal vein CT value was(73.03±26.16).(P=0.402, 0.266, 0.687, 0.237, 0.952, 0.700, χ2=0.703,1.236, 0.406,-1.999,-0.061,-0.387). Conclusion CT imaging features of high-to-moderate and low-risk groups of gastric stromal tumors have important reference value for the classification of the risk of gastric stromal tumors.

胃肠道间质瘤(GIST)是发生于胃肠道黏膜下的间叶源性肿瘤,胃间质瘤占全部消化道肿瘤的60%~70% 左右[1]。根据生物学行为,GST可分不同的危险度等级,采用Miettinen病理分级标准,分为高危险、中危险、低危险、极低危险,Nilsson等[2-3]研究显示,高中危险度组 GST 的复发率及死亡率均高于其他级别的危险度组。该文回顾性分析2015年4月—2017年12月之间50例不同危险度分组胃间质瘤的影像CT,探讨CT检查在不同级别胃间质瘤危险度分级中的价值,现报道如下。
