The diagnosis and treatment of gastrointestinal stromal tumor (GIST) is getting more and more standardized. In the last two decades, due to the elucidation of molecular mechanism of tumorigenesis, as well as the effectiveness of tyrosine kinase inhibitors, GIST has become well-known as one of the most classical models of targeted therapy on solid tumors in the precision medicine era. The National Comprehensive Cancer Network (NCCN) issued the latest version of clinical practice guideline on soft tissue sarcoma in February 2020. Compared with previous versions, the new version of the guideline highlighted the treatment recommendations of avapritinib, which further promoted the precise targeted treatment of GIST.
胃肠间质瘤（GIST）的诊断和治疗已日趋标准化和规范化。近20年来，随着分子水平发病机制的揭示和小分子酪氨酸激酶受体抑制剂的成功应用，GIST治疗已经成为精准医疗时代最经典的实体肿瘤靶向治疗成功范例之一。2020年2月，美国国家综合癌症网络（NCCN）发布了最新版的《软组织肉瘤临床实践指南（2019年第6版）》，与既往版本相比，新版指南中的一大亮点是更新了靶向新药avapritinib的治疗推荐，进一步推动了GIST的精准靶向治疗。.
