homozygous mutationKITprognosisBackground Gastrointestinal stromal tumors (GISTs) with different types of mutations exhibit different clinical characteristics and prognosis. This study aimed to evaluate the prognostic value of mutations in KIT and PDGFRA in a large‐scale cohort of GIST patients with ...
GIST tumor with c kit exon 11 mutation has disease progression after 2 years of imatinib Why? It gained a new mutation in exon 17 (active loop) Can I use sunitinib? No. A loop mutation is resi...
Median progression-free survival with imatinib were 21.9 and 18.9 months for patients with GIST with delTyr (n=14) and delWK (n=22), respectively (P=0.43).Conclusion:In this large retrospective series, the type of KIT exon 11 mutation was correlated with the origin of GIST, but not with...
A specific mutation in the tyrosine kinase domain of c-kit has been found in mast cell neoplasms.18 Mutations between the transmembrane and tyrosine kinase domains in exon 11 of c-kit have been shown in GISTs7, 19 and in a mast cell leukemia cell line.20 The c-kit mutations in GISTs ...

Anevaluation of the p.His845_Asn848delinsPro mutation involving exon 18 of PDGFRA in a metastatic GIST patient responding to first-line imatinib has been provided. Docking analyses were performed, and the ligand-receptor interactions were evaluated with the jCE algorithm for structural alignment. ...

)are derived from the interstitial cells of Cajal,and are the most common mesenchymal tumors of the gastrointestinal tract[1].KIT proto-oncogene,receptor tyrosine kinase(KIT),and platelet-derived growth factor receptor alpha(PDGFRA)gene mutations are found in approximately 85%–90% cases of GIST....

KIT mutationprognostic factorAimBenefit of adjuvant imatinib therapy following curative resection in patients with intermediate-risk gastrointestinal stromal tumor (GIST) is unclear. GIST-specific exon mutations, in particular exon 11 deletions, have been shown to be prognostic. We hypothesize that ...
