Intrahepatic cholangiocarcinoma patient with epidermal growth factor receptor exon 19 deletion unresponsive to Afatinib monotherapy: a case report

Abstract Background The efficacy of epidermal growth factor receptor EGFR tyrosine kinase inhibitors in cholangiocarcinoma (CCA) patients is still unknown. Here, we report a 67-year-old CCA patient with EGFR exon 19 deletion receiving afatinib treatment. Case description A 67-year-old male was refer...

description Abstract Background The efficacy of epidermal growth factor receptor EGFR tyrosine kinase inhibitors in cholangiocarcinoma (CCA) patients is still unknown. Here, we report a 67-year-old CCA patient with EGFR exon 19 deletion receiving afatinib treatment. Case description A 67-year-old male was referred to our hospital due to persistent abdominal pain for 3 months. Abdominal computed tomography showed a tumor with a diameter of 92 mm in the left liver with multiple intrahepatic metastases. Immunohistochemistry revealed that tumor cells were positive for CK7 and CK19, and negative for hepatocyte and CDX- 2. A pathological diagnosis of intrahepatic CCA was made. Since the patient declined standard chemotherapy, afatinib was administered as the first-line treatment. Upon disease progression, apatinib was introduced. Unfortunately, the patient ultimately succumbed to hepatic failure, with a total survival of 1.8 months. Conclusion In this report, the CCA patient with EGFR exon 19 deletion was unresponsive to afatinib treatment. However, genetic testing may be still worthwhile for CCA to increase the possible treatment options.
