Frequencies of KIT and PDGFRA mutations in the MolecGIST prospective population-based study differ from those of advanced GISTs

Abstract: Gastrointestinal stromal tumors (GISTs) are the most common human sarcoma. Most of the data available on GISTs derive from retrospective studies of patients referred to oncology centers. The MolecGIST study sought to determine and correlate clinicopathological and molecular characteristics of GISTs. Tumor samples and clinical records were prospectively obtained and reviewed for patients diagnosed in France during a 24-month period. Five hundred and ninety-six patients were included, of whom 10% had synchronous… Show more

“…KIT is a member of the type III transmembrane receptor tyrosine kinase family (39). 70-80% of GIST possess a KIT gene mutation, which were found at exon 11(50-77%), exon 9 (10-18%), exons 13 (1-4%) and exons 17 (1-4%) (40)(41)(42)(43)(44)(45)(46). All of the above are the first diagnostic biomarkers.…”

“…Les GIST surviennent plus fréquemment à l'âge adulte, avec un âge médian d'environ 60 ans et une fréquence équivalente dans les deux sexes [4]. Elles se développent souvent à partir de l'estomac (60 %) ou de l'intestin grêle (25 %).…”

“…Les GIST sont de pronostic très variable, certaines ne récidivent pas après résection chirurgicale, d'autres ont une évolution métastatique rapidement catastrophique. Au moment du diagnostic, 10 % des GIST sont au stade métastatique [4]. Pour les tumeurs localisées, le risque de récidive est actuellement évalué en fonction de la localisation primitive, de la taille et de l'activité mitotique (Tableau I).…”
