Gain-of-function mutations inKITorPDGFRAreceptor tyrosine kinase are key drivers of most gastrointestinal stromal tumor (GIST). The continuous development of tyrosine kinase inhibitors, such as imatinib, sunitinib, anlotinib, regorafenib, ripretinib and avapritinib, has greatly improved the overall survival of patients with advanced GIST. This article reviewed the efficacy (including objective response rate, disease stability rate, median progression free survival) and common adverse events of representative tyrosine kinase inhibitors in the treatment of advanced GIST in recent years, aiming to provide a clinical basis for the treatment options of patients with advanced GIST.
