Gastrointestinal stromal tumor (GIST) is the most common mesenchymal tumor of the gastrointestinal tract. Its pathogenesis is defined by mutations within the KIT and PDGFRα gene. Surgical resection is the only radical treatment at present, but recurrence is common. In recent years, targeted therapy with imatinib mesylate, which inhibits KIT kinase activity, represents the other cornerstone for the treatment of GIST. For resectable GIST, operation combined with neoadjuvant and adjuvant therapy with imatinib mesylate or other tyrosine kinase inhibitors can improve the prognosis of high-risk patients before or after complete resection. For unresectable GIST, targeted therapy with imatinib mesylate can effectively inhibit and ameliorate the progression of GIST.
胃肠道间质瘤(GIST)是胃肠道最常见的间叶组织肿瘤。其发病机制由KIT和PDGFRα基因突变所决定。手术切除是目前唯一的根治性治疗方法,但复发很常见。近年来,抑制KIT激酶活性的甲磺酸伊马替尼靶向治疗是GIST治疗的另一基石。对于可切除的GIST,手术联合甲磺酸伊马替尼或其他酪氨酸激酶抑制剂的新辅助和辅助治疗可改善高危患者在完全切除前后的预后。对于不可切除的GIST,甲磺酸伊马替尼靶向治疗可有效抑制并改善GIST的进展。
