Pathologic complete response after gemcitabine and S-1 chemotherapy for far advanced intrahepatic cholangiocarcinoma

Abstract

We report the case of a 72-year-old man who was initially diagnosed with far advanced intrahepatic cholangiocarcinoma, associated with bulky lymph node metastasis involving the common hepatic artery and moderate amount of ascites around the liver. After 10 cycles of systemic chemotherapy combining gemcitabine and S-1 with well-tolerated toxicities, a CT scan showed a marked shrinkage of the liver mass and lymph nodes (clinical partial response) with disappearance of ascites, which could permit a radical resection of the tumor. He underwent left lobectomy of the liver with lymph node dissection, and histopathological examination revealed pathologic complete response. Seven years after surgery, he is in a good overall condition.
