【摘要】目的 分析DOG1蛋白与胃肠道间质瘤(GIST)的相关性.方法 收集2005年1月至2010年6月77例GIST患者,应用免疫组化法检测GIST中DOG1蛋白的表达,并结合原有免疫组化指标CD117、CD34的检测结果进行对照分析.结果 77例GIST患者中,DOG1蛋白和CD117的阳性表达率分别为96.1%(74/77)和90.9%(70/77),两组间差异无统计学意义(P＞0.05).不同性别、年龄组、病变部位及危险度间DOG1蛋白阳性表达率差异亦无统计学意义(P值均＞0.05).7例CD117阴性表达的GIST患者中6例DOG1蛋白阳性表达.3例DOG1蛋白阴性表达的GIST中2例CD117阳性表达.结论 DOG1蛋白作为一种新的GIST标志物,具有与CD117同样的高敏感性,与CD117联用于GIST诊断互补性较好,尤其对CD117阴性的GlST诊断价值优势较大,但不能作为划分GIST危险度的指标.%Objective To analyze the association of DOG1 protein with gastrointestinal stromal tumors(GIST). Methods Seventy-seven patients diagnosed with GIST between January 2005 and June 2010 were enrolled. The DOG1 expression in GIST was determined using immunohistochemistry.The result was compared with that of CD117 and CD34. Results Of 77 GIST patients, the DOG1 was expressed in 74 (96.10%) patients and CD117 in 70 (90. 9%) patients, with no significant difference between DOG1 and CD117 (P＞0.05). DOG1 expression was
not related to the risk stratification of the tumor, site, age and gender (P＞0. 05). Of 7 GIST patients with negative CD117,6 patients were positive for DOG1 expression. Whereas 2 of 3 DOG1 negative patients were positive for CD117 expression. Conclusions DOG1, as a novel marker for GIST,has high sensitivity as CD117. It is a good complementarity in diagnosis of GIST when combine DOG1 with CD117, especially in diagnosis of CD117 negative patients. However, the DOG1 can not be used as an index in eveluating the risk stratification of the GIST.
