Postpartum related intrahepatic cholangiocarcinoma with FGFR2 fusion and severe hyperbilirubinemia with response to FGFR inhibitor pemigatinib: case report and review

Background

Cholangiocarcinoma during postpartum or pregnancy is a rare presentation. There are limited cases reported in the literature. Diagnosis can be delayed as presenting signs and symptoms may be attributed to pregnancy or postpartum state.

Case Description

We present the case of a 33-year-old postpartum woman with intrahepatic cholangiocarcinoma with severe hyperbilirubinemia who was found to have fibroblast growth factor receptor 2 (FGFR2)-adenosylhomocysteinase like 1 (AHCYL1) fusion on next-generation sequencing (NGS). She initially was treated with two doses of gemcitabine and cisplatin with increasing hyperbilirubinemia requiring hold of further chemotherapy. NGS showed FGFR2-AHCYL1 fusion, and she was started on the FGFR inhibitor pemigatinib, with dramatically decreasing bilirubin within 10 days. She eventually normalized her bilirubin values and had partial response on follow-up imaging.

Conclusions

This is the first report, to our knowledge of response to an FGFR inhibitor in the postpartum setting, as well to show response in the setting of life-threatening hyperbilirubinemia. Our patient did not tolerate standard chemotherapy, likely due to liver dysfunction, but responded to pemigatinib, suggesting that the liver dysfunction was driven by her disease. This case underscores the need to include NGS as part of initial workup to identify important therapeutic targets and increase available lines of therapy, including those patients who are postpartum or pregnant.

EASL Clinical Practice Guidelines on the management of liver diseases in pregnancy

Liver diseases in pregnancy comprise both gestational liver disorders and acute and chronic hepatic disorders occurring coincidentally in pregnancy. Whether related to pregnancy or pre-existing, liver diseases in pregnancy are associated with a significant risk of maternal and fetal morbidity and mortality. Thus, the European Association for the Study of Liver Disease invited a panel of experts to develop clinical practice guidelines aimed at providing recommendations, based on the best available evidence, for the management of liver disease in pregnancy for hepatologists, gastroenterologists, obstetric physicians, general physicians, obstetricians, specialists in training and other healthcare professionals who provide care for this patient population.
