KIT exon 11 del | gastrointestinal stromal tumor | predicted - sensitive | Imatinib | Phase III | Actionable | In a Phase III trial, 3-year adjuvant Gleevec (imatinib) treatment resulted in an improved 10-year overall survival rate (86% vs 64%, HR=0.34, p=0.0007) and 10-year recurrence-free survival rate (47% vs 29%, HR=0.48, p<0.001) compared to 1-year adjuvant treatment in patients with gastrointestinal stromal tumors harboring KIT exon 11 deletion or indel mutations (PMID: 37014660; NCT00116935). | 37014660 |
KIT exon 11 del | gastrointestinal stromal tumor | predicted - sensitive | Imatinib | Preclinical - Cell culture | Actionable | In a preclinical study, Gleevec (imatinib) inhibited Kit phosphorylation and proliferation of gastrointestinal stromal tumor cells harboring KIT exon 11 deletion in culture (PMID: 31085175). | 31085175 |
KIT exon 11 del | gastrointestinal stromal tumor | predicted - sensitive | Imatinib | Phase III | Actionable | In a Phase III trial, gastrointestinal stromal tumor patients harboring KIT exon 11 deletions or indels demonstrated improved recurrence-free survival (RFS) with 3-year adjuvant Gleevec (imatinib) treatment (5-year RFS, 70%), compared to patients receiving 1-year treatment (5-year RFS, 41.3%) (PMID: 28334365). | 28334365 |
