[A Case of Intrahepatic Cholangiocarcinoma in the Elderly Patient with Curative Resection after Neoadjuvant Chemotherapy].

An 80 year-old woman with anorexia and jaundice was diagnosed with mass-forming intrahepatic cholangiocarcinoma, lymph node metastasis, common hepatic duct strictures, and obstructive jaundice. PET-CT showed FDG accumulation in the primary lesion(SUVmax 19.0)and swollen lymph nodes. Her ADL and major organ functions were judged to be sufficient for treatment. After treatment for jaundice, she received a total of 6 courses of gemcitabine, cisplatin plus S-1(GCS)therapy as neoadjuvant chemotherapy(NAC). Her first treatment was an 80% dose of GCS, but she was subsequently diagnosed with Grade 4 thrombocytopenia(CTCAE v5.0). The dose of gemcitabine was further reduced, and no adverse events of Grade 3 or higher were observed thereafter. After NAC, PET-CT showed decreased FDG accumulation in the primary lesion(SUVmax 3.3)and normalization of FDG accumulation in the lymph nodes. Extended right hepatectomy and biliary reconstruction were performed as radical resection(R0). The final diagnosis was pT2, N0, M0, Stage Ⅱ. After hepatectomy, her anorexia and poor ADL persisted. She was discharged to her home 151 days after her surgery.
