KIT exon9 (unknown)

Relevant Treatment Approaches

Filtering

  • Case insensitive filtering will display rows where any text in any cell matches the filter term
  • Simple literal full or partial string matches
  • Separate multiple filter terms with a spaces, order doesn't matter (a b c and c b a are equivalent )
  • Filtering will only apply to rows that are already loaded on the page, filtering has no impact on query parameters
  • Use quotes to match a longer phrase which contains spaces "mtor c1483f"

Sorting

  • Generally, the default sort order for tables is set to be first column ascending, however, specific tables may set a different default sort order.
  • Click on any column header arrows to sort by that column
  • Hold down the Shift key and click multiple columns to sort by more than one column, be sure to set ascending or descending order for a given column, before moving on to the next column.

KIT exon 9 Advanced Solid Tumor sensitive Ponatinib Preclinical Actionable In a preclinical study, transformed cells expressing a KIT exon 9 mutation demonstrated sensitivity to treatment with Iclusig (ponatinib) in culture, resulting in reduced cell viability (PMID: 25239608). 25239608
KIT exon 9 Advanced Solid Tumor sensitive Sunitinib Preclinical Actionable In a preclinical study, transformed cells expressing a KIT exon 9 mutation demonstrated sensitivity to treatment with Sutent (sunitinib) in culture, resulting in reduced cell viability (PMID: 25239608). 25239608
KIT exon 9 Advanced Solid Tumor resistant Regorafenib Preclinical Actionable In a preclinical study, Stivarga (regorafineb) had no effect on transformed cells expressing a KIT exon 9 mutation in culture (PMID: 25239608). 25239608
KIT exon 9 gastrointestinal stromal tumor predicted - sensitive Sunitinib Clinical Study Actionable In a retrospective analysis, GIST patients with KIT exon 9 mutations showed improved progression-free survival (PFS), overall survival, and objective response rate (ORR) compared to patients with exon 11 mutations, with a median PFS of 12.3 months vs. 7.0 months, and an ORR of 19% (8/42) vs. 6% (9/143) following treatment with Sutent (sunitinib) (PMID: 26772734). 26772734
