| 摘 要： | 目的探讨胃肠间质瘤(gastrointestinal stromal tumor,GIST)CT诊断价值。方法回顾性分析39例经手术病理和免疫组织化学证实的GIST患者的临床及CT检查资料,并将CT表现与病理诊断进行对照。结果39例GIST中,良性共9例,恶性共30例。发生在胃肠道26例恶性19例,发生在胃肠道外13例恶性11例;肿瘤5cm组14例恶性7例,肿瘤≥5cm组25例恶性23例;有囊变坏死30例恶性29例,无囊变坏死9例恶性1例;11例有转移均为恶性,28例无转移恶性19例。GIST的发病部位、大小、有无囊变坏死及转移对肿瘤的良恶性的鉴别有统计学差异(P0.05)。发生在胃肠道外的GIST恶性程度高,肿瘤≥5cm组恶性程度较高,且肿瘤的大小与肿瘤恶性程度呈显著正相关,有囊变坏死及转移的GIST恶性程度高。结论CT检查对GIST的定位、定性诊断有重要价值,多种CT征象有助于对GIST良、恶性做出准确判断。

| Abstract: | Objective To investigate the malignant degree diagnostic value of CT in gastrointestinal stromal tumor(GIST). Methods CT data of 39 cases with GIST confirmed by pathology and immunohistochemistry were retrospectively analyzed. The CT features of GIST were compared with the pathologic findings. Results In 39 cases of GIST,the total benign tumors were 9 cases, malignant tumors were 30 cases. Tumors situated at gastrointestinal tract were 26 cases with malignant tumor 19 cases, extra-gastrointestinal tract 13 ... |
