A case of unresectable locally advanced intrahepatic cholangiocarcinoma that achieved pathological complete response after gemcitabine and S1 chemotherapy

Abstract

The standard chemotherapy for patients with unresectable cholangiocarcinoma is gemcitabine plus cisplatin, and gemcitabine plus S-1 (GS) chemotherapy is also reported to have similar effectiveness in Japan. However, the response rates of these two chemotherapies were modest, and no patients with intrahepatic cholangiocarcinoma (ICC) have shown a pathological complete response (pCR) following these chemotherapies. We report here the first case of an initially unresectable locally advanced ICC that achieved pCR following GS chemotherapy.
