目的探讨胃肠道间质瘤的MSCT影像特征及生物学危险度评价。方法回顾性分析21例经手术病理证实的GIST临床资料及CT表现,结合文献分析与肿瘤危险度相关的MSCT征象。结果 21例患者肿瘤极低危险度1例(4.8%),低危险度2例(9.5%),中等危险度5例(23.8%),高危险度13例(61.9%)。GIST的生特学危险度与肿瘤的大小、形态、密度、边界以及肿瘤坏死出血、邻近器官侵犯、转移有关,差异具有显著的统计学意义(P<0.05)。而GIST的生特学危险度与肿瘤增强程度、钙化无显著统计学差异(P>0.05)。结论 GIST的MSCT有一定的影像特征,CT征象能较好地反映GIST的病理组织学特点,有助于肿瘤生物学危险度的评价。
Objective To investigate the characteristics and biological risk assessment of MSCT in gastrointestinal stromal tumors. Methods A retrospective analysis of 21 cases of pathologically confirmed GIST clinical data and CT findings, combined with literature analysis of tumor risk associated with MSCT signs. Results Twenty-one patients had extremely low-risk cancer (1%, 4.8%), 2 low-risk patients (9.5%), 5 moderate risk patients (23.8%) and 13 high-risk patients (61.9%). The biogenetic risk of GIST was related to tumor size, morphology, density, border, tumor necrosis, adjacent organ invasion and metastasis, and the difference was statistically significant (P <0.05). However, there was no significant difference in calcification between GIST and malignant tumors (P> 0.05). Conclusion MSCT of GIST has certain imaging features. CT signs can better reflect the histopathological features of GIST and contribute to the evaluation of tumor biological risk.
