摘要 目的探讨胃肠道间质瘤的病理和免疫组化的特点及之间的关系。方法免疫组化标记CD117、CD34、SMA、S-100蛋白4种抗体于胃肠道间叶源性肿瘤,确诊24例间质瘤,对其进行临床病理组织学和免疫组化分析。结果免疫组化显示24例GIST中CD117阳性表达率为87.5%,CD34的阳性表达率为79.2%;SMA的阳性表达率为41.7%;S-100的阳性表达率为8.3%。结论CD117、CD34对胃肠间质瘤特异性表达,具有临床应用的价值。GIST多发于中老年,肿瘤细胞形态多样,结构多样;免疫组化CD117和CD34阳性表达是确诊间质瘤最有诊断价值的依据,但间质瘤良、恶性诊断上仍需结合肿瘤的大体、组织学形态及生物学行为等综合考虑。
