An overview on molecular biology of KIT/PDGFRA wild type (WT) gastrointestinal stromal tumours (GIST)

Abstract excerpt

BACKGROUND: About 85% of paediatric gastrointestinal stromal tumours (GISTs) and about 10-15% of adult GISTs do not harbour any mutations in the KIT and PDGFRA genes and are defined as KIT/PDGFRA wild type (WT). Over the years it has been demonstrated that KIT/PDGFRA WT GISTs are profoundly different from mutant GIST in clinical and molecular profiles, so that they are now considered a separate pathological...
