胃肠道间质瘤临床病理分析(1)
摘要:目的 探讨胃肠间质瘤的临床病理特点。方法 回顾分析淮南东方医院集团总院2012年10月~2016年10月收治的30例GIST 的临床资料及病理特征。结果 30例GIST中,男性15例,女性15 例,平均年齡63.8岁。临床表现为腹部隐痛、腹胀不适等非特异性症状。肿瘤发生部位为胃23例,小肠6例,1例位于肠系膜。30例中梭形细胞型29 例,混合细胞型1 例。免疫组化:CD117(+)阳性率83.30%,DOGl(+)阳性率94.40%,CD34(+)阳性率70.00%,vimentin阳性率100.00%,SMA(+)阳性率6.70%,desmin及S-100均(-)。结论 胃肠道间质瘤缺乏临床特异性,极易误诊,形态学、免疫组化及分子病理检测有助于GIST的诊断。

Abstract:Objective To investigate the clinicopathological features of gastrointestinal stromal tumors.Methods The clinical data and pathologic features of 30 cases of GIST were analyzed retrospectively from October 2012 to October 2016 in Huainan Dongfang Hospital.Results 30 cases of GIST,15 males and 15 females,the average age of 63.8 years old.Clinical manifestations of abdominal pain,abdominal distension and other non-specific symptoms.The tumor was 23 cases of stomach,6 cases of small intestine,1 in the mesentery.30 cases of spindle cell type in 29 cases,mixed cell type in 1 case.Immunohistochemistry:the positive rate of CD117(+)was 83.30%,The positive rate of DOGl(+)was 94.40%,the positive rate of CD34(+)was 70.00%, the positive rate of vimentin was 100.00%,the positive rate of SMA(+)was 6.70%,desmin and S-100 were(-).Conclusion Gastrointestinal stromal tumors lack clinical specificity,easily misdiagnosed,morphological,immunohistochemical and molecular pathologic detection contribute to the diagnosis of GIST.

大部分胃肠道间叶性肿瘤为胃肠间质瘤(gastrointestinal stromal tumor,GIST),约占胃肠道肿瘤1%~2%,中位发病年龄为40~60 岁。发生部位从食管到肛门,其中60%~70% 起源于胃,20%~30%起源于小肠,其他部位少见[1]。GIST起源于胃肠道Cajal 间质细胞,是c-kit或PDGFRα基因获得功能性突变所致。GIST生物学行为多变,临床表现缺乏特异性,极易误诊。现将本院收治30例GIST病例,并复习相关文献,总结分析如下。
1 资料与方法
1.1 一般资料
, http://www.100md.com 收集30例来自我院病理科2012年10月~2016年10月诊断为胃肠道间质瘤的病例。男性15例,女性15例,平均年龄63.8岁,其中≥60岁者22例(73.30%)。30例病例中27例有临床症状,主要为腹部隐痛、腹胀不适等非特异性症状。另外体检发现1例、其他手术发现2例。肿瘤发生于胃23例,小肠6例,肠系膜1例。
1.2方法
1.2.1病理形态观察及免疫组织化学检测 将标本连续间隔1 cm切开,10%中性福尔马林固定,常规取材,切片,染色,光镜观察。免疫组化采用SP染色法,检测CD117、CD34、DOG1、S-100、SMA、Desmin、vimentin、CKpan、Ki-67。上述抗体及试剂盒均购自福州迈新生物技术有限公司。
1.2.2免疫组化结果判定 CD117、DOGl、SMA、Des、CKpan 、vimentin 和CD34 阳性部位出现在相应细胞浆/包膜,S-100阳性部分出现在相应细胞浆和核,Ki-67细胞核着色为阳性。, 百拇医药(祁真玉 曹娟 王骏 王干勋)
