Molecular profiling for early patient identification — 2 of 2

Testing for FGFR2 fusions or rearrangements can inform treatment decisions in CCA

The high frequency of actionable alterations in patients with CCA strongly supports the use of molecular testing in this population12,17

FGFR2 fusions have a wide range of fusion partners.17 Therefore, to identify patients with FGFR2 fusions, it is important to select an appropriate assay that:


White tick

Can detect FGFR2 fusions (which are distinct from FGFR2 point mutations)17–19

White tick

Can detect all FGFR2 fusions, including those with known or unknown fusion partners17–19

ESMO Clinical Practice Guidelines for BTC recommend:

  • Performing molecular profiling before or during 1L therapy, using parallel DNA- and RNA-based NGS assays with panels
    which include FGFR2, IDH1, HER2/neu and BRAF to test for hotspot mutations, and which may also include genes such as NTRK and c-MET12
  • Using the molecular profiling results to determine eligibility for 2L targeted therapies, such as PEMAZYRE, should the patient experience disease progression on 1 L therapy12
