Abstract:
Introduction: Gastrointestinal stromal tumour (GIST) is a common gastrointestinal
sarcoma located in the stromal cells of the digestive tract, and molecular studies
have revealed the pathogenesis of mutations in KIT and PDGFRA genes. Since imatinib
opened the era of targeted therapy for GIST, tyrosine kinase inhibitors (TKIs) that can
treat GIST have been developed successively. However, the lack of new drugs with satisfactory
therapeutic standards has made addressing resistance a significant challenge for
TKIs in the face of the resistance to first-line and second-line drugs. Therefore, we need
to find as many drugs and new treatments that block mutated genes as possible.
Methods: We conducted a comprehensive collection of literature using databases, integrated
and analysed the selected literature based on keywords and the comprehensive nature
of the articles, and finally wrote articles based on the content of the studies.
Results: In this article, we first briefly explained the relationship between GIST and KIT/
PDGFRα and then introduced the related drug treatment. The research progress of TKIs
was analyzed according to the resistance of the drugs.
Conclusion: This article describes the research progress of some TKIs and briefly introduces
the currently approved TKIs and some drugs under investigation that may have better
therapeutic effects, hoping to provide clues to the research of new drugs.
