CT和超声内镜诊断胃肠道间质瘤的现状

The status of CT and EUS in diagnosing gastrointestinal stromal tumor

胃肠道间质瘤是原发于胃肠道和腹部的间叶源性肿瘤,绝大多数存在c-Kit基因突变。内镜检查胃肠道间质瘤有一定困难,而CT和超声内镜结合有助于胃肠道间质瘤的定位和良、恶性的判断,对指导临床治疗和估计预后有一定的价值。

Gastrointestinal stromal tumors （GIST） is the most common mesenchymal tumors of the gastrointestinal tract. Activating mutations of KIT has been identified in the vast majority of GIST. Endoscopic diagnosis of GIST is usually difficult. CT combined with EUS are helpful in evaluating the gastrointestinal origin of GIST, and in differentiating between benign and malignant GIST, and in instructing clinical treatment and estimating prognosis.
