Abstract Text Advanced gall bladder cancer (GBC) is an aggressive disease, and there is no consensus on treatment options beyond first-line chemotherapy. We report a case of an elderly male with FGFR2-altered advanced adenocarcinoma of the gallbladder who failed two prior lines of chemotherapy but had sustained response and stable disease on sequential FGFR-directed targeted therapy.We describe a case of FGFR2-altered metastatic adenocarcinoma of the gallbladder who failed two prior lines of chemotherapy. The treatment was based on comprehensive genomic profiling when the patient was found to have FGFR2 single amino acid mutation (S252W) in one of his tissue samples. A novel therapeutic regimen with sequential anti-FGFR tyrosine kinase inhibitors was later initiated.The patient tolerated the sequential targeted therapy very well and had a sustained response and stable disease. He had an overall survival of nearly five years. Unfortunately, GBC is an aggressive disease, and there is no consensus on treatment options beyond first-line chemotherapy.Through this patient, we demonstrate that advanced-metastatic GBC with FGFR alterations can be maintained on anti-FGFR therapy for prolonged periods of time, with improved survival. Therefore, we endorse the need for comprehensive genomic profiling in advanced-metastatic GBC and the need to study the role of FGFR inhibitors as a viable treatment option in these patients.

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.
