摘要
目的探讨提高胃肠道间质瘤(GIST)术前诊断的方法。方法回顾性分析2002年1月至2005年12月24例GIST患者的临床及诊断资料。结果症状以消化道出血为主者占54%,最常见的发生部位为胃,占62%,CT检查阳性率为79%,B超检查阳性率为41%,术前病理活检多为丰富的梭形细胞及上皮细胞,直径＜2 cm的肿块100%为低侵袭性的,CD117阳性率为96%、CD34阳性率为66%。结论提高对GIST的认识及多种检查结合有助于提高术前检出率,CT检查有其特殊价值,肿块直径在2 cm以下的GIST有良性倾向。
Objective To appraise the way of improving preoperative diagnosis of gastrointestinal stromal tumors（GIST）. Methods Retrospectively analyzed the clinical and diagnostic data of 24 cases with GIST from January 2002 to December 2005 in our hospital. Results Among all the patients In this group, gastrointestinal bleeding occupied 54 % ; with stomach as the most common site of bleeding（62 % ）. The positive diagnosis by CT and ul- trasound were 79% and 41 % respectively. Preoperative biopsy mostly showed plethoric spindle-shape cells and epithelial cells. Tumor less than 2 cm was less invasive. Positive CDll7 occurred in 96% and positive CD34 in 66%. Conclusions Heightening our knowledge about GIST,with combined multidetection methods would be able to improve the preoperative diagnostic rate, among which, CT scan has its special value as the first choice. Tumor less than 2 cm tends to be benign. （Shanghai Med J, 2006, 29：656-658）
