| 目的 观察多期相CT联合预测最大径≤5 cm胃间质瘤(GST)危险度的价值。方法 回顾性纳入329例最大径≤5 cm GST患者,根据术后病理结果将其分为低危组(n=262)与高危组(n=67);比较组间临床及CT资料,行logistic回归分析,构建模型并观察其预测GST危险度的效能。结果 组间肿瘤最大径及坏死、表面溃疡、增粗肿瘤滋养或引流血管(EVFDM)占比差异均有统计学意义(P均＜0.05),其他临床及CT资料差异均无统计学意义(P均＞0.05)。肿瘤最大径、表面溃疡率及EVFDM出现率均为最大径≤5 cm GST危险度的独立预测因素(P均＜0.05),三者联合预测其危险度的敏感度、特异度及曲线下面积分别为64.23%、80.94%及0.760。结论 多期相CT所示肿瘤最大径、表面溃疡及EVFDM有助于预测最大径≤5 cm GST的危险度。 |

| Objective To observe the value of multi-phase CT for predicting the risk of gastric stromal tumor (GST) with the maximum diameter≤5 cm. Methods Totally 329 GST patients with the maximum diameter≤5 cm were retrospectively enrolled, and divided into low-risk group (n=262) and high-risk group (n=67) based on postoperative pathological result. The clinical and CT data were compared between groups, logistic regression analysis was performed to construct a model, and its efficacy for predicting GST risk was analyzed. Results Significant differences in tumor maximum diameter and the proportion of necrosis, surface ulcers and enlarged vessel feeding or draining the mass (EVFDM) were found between low-risk group and high-risk group (all P＜0.05), while no significant differences in other clinical and CT data (all P＞0.05).Tumor maximum diameter, surface ulcers rate and the incidence of EVFDM were independent predictive factors of the risk of GST with the maximum diameter≤5 cm. The sensitivity, specificity and area under the curve of the combination of above three for predicting the risk of GST with the maximum diameter≤5 cm was 64.23%, 80.94% and 0.760, respectively. Conclusion The tumor maximum diameter, surface ulcers rate and the incidence of EVFDM based on multi-phase CT could help for predicting the risk of GST with the maximum diameter≤5 cm. |
