FGFR2 L618F (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.

FGFR2 H167_N173del FGFR2 L618F intrahepatic cholangiocarcinoma predicted - resistant Debio 1347 Case Reports/Case Series Actionable In a Phase I trial, an intrahepatic cholangioncarcinoma patient who progressed in Debio 1347 was found to have acquired FGFR2 L618F, and co-expression of FGFR2 H167_N173del and FGFR2 L618F an intrahepatic cholangiocarcinoma cell line led to a reduced response to Debio 1347 treatment compared to cells expressing wild-type FGFR2 in culture (PMID: 33926920). 33926920
FGFR2 H167_N173del FGFR2 L618F intrahepatic cholangiocarcinoma predicted - sensitive Futibatinib Case Reports/Case Series Actionable In a Phase I trial, Futibatinib (TAS-120) treatment led to a partial response with 61% tumor reduction and response duration of 17 months in an intrahepatic cholangiocarcinoma patient harboring FGFR2 H167_N173del and FGFR2 L618F, which was consistent with inhibition of growth in an intrahepatic cholangiocarcinoma cell line expressing FGFR2 H167_N173del and FGFR2 L618F in culture (PMID: 33926920). 33926920
