Neoadjuvant Pemigatinib as a Bridge to Living Donor Liver Transplantation for Intrahepatic Cholangiocarcinoma with FGFR2 Rearrangement.

Abstract

We report a case of a 55-year-old male with intrahepatic cholangiocarcinoma (iCCA) who underwent living donor liver transplantation (LDLT) after complete radiographic response on second line pemigatinib. LDLT for iCCA is controversial, but recent reports have cited the potential benefit for patients with unresectable disease, especially those with disease stability after 6 months of systemic therapy. Concomitantly, genomic profiling has identified potentially treatable oncologic targets in iCCA. This patient's tumor genomic profile revealed a FGFR2 rearrangement and was treated with pemigatinib, a competitive inhibitor for FGFR1/2/3. This resulted in complete radiographic and metabolic response after two months of treatment. He was considered eligible for LDLT after 6 months of observation on treatment with sustained response. He underwent an uncomplicated LDLT (including an uncomplicated donor surgery) and at one year follow-up is without evidence of disease recurrence. We believe this is the first report of LDLT for this indication.
