摘要
目的:探讨胃肠道间质瘤(GIST)的临床表现、病理学和免疫组化特点及诊断、治疗方法。方法:对57例GISTs患者的临床资料和病理资料进行回顾性分析。结果:GIST主要发生在胃和小肠,结肠、直肠和肠系膜较少;内窥镜检查阳性率89%,消化道造影阳性率77%,CT阳性率为97%;免疫组织化学染色显示CD117、CD34表达的阳性率分别是84.2%、73.2%。结论:GIST是一种具有潜在恶性的肿瘤,其确诊有赖于病理组织学和免疫组化检查,CD34和CD117阳性在诊断上有其特殊意义;手术仍是主要治疗手段。
Objective :To explore the clinical behavior, Pathological and immunohistochemical characteristics and diagnosis, and treatment methods of gastrointestinal stromal tumors (GIST). Methods:Retrospective analysis was perfomed over 57 GISTs patients based on clinical data and pathological data. Results : GIST occurred more in the stomach and small intestine, than colon, rectum and mesenteric. Endoscopy positive rate was 89 %, gastrointestinal imaging positive rate was 77%, CT - positive rate was 97 %. Immunohistochemical staining showed CD117, CD34 expression, the positive rates were 84.2%, 73.2%. Conclusion : GIST is a potentially malignant tumor. GIST diagnosis depends on the histologic and immunohistochemical test. CD34 and CD117 in the positive diagnosis has its special significance. Surgery is the main treatment.
