RESUMO
Case 1 consisted of an 86-year-old male diagnosed with intrahepatic cholangiocarcinoma(ICC), approximately 11 cm in diameter, at segment S7/8 of the liver. A total of 4 percutaneous radiofrequency ablations(PRFA)and 3 hepatic arterial infusion chemotherapies(HAIC)of 5-FU were performed. He died after developing lung metastases 27 months after the initial treatment. Case 2 was an 85-year-old female diagnosed with ICC, 8 cm in diameter, at the posterior segment of the liver, with lymph node metastasis. She underwent HAIC of 5-FU and S-1 as well as gemcitabine-based systemic chemotherapy. The main tumor developed 10 months after the initial treatment, and PRFAs were subsequently performed twice for the main lesion. Although the tumor markers gradually decreased, she died of jaundice 33 months after the initial treatment. As one of the multidisciplinary therapies for the giant ICC, ablation therapy may be safe and effective in elderly patients.
