An 82-year-old man was referred to our hospital after a hepatic tumor was identified on ultrasonography.Computed tomography(CT)revealed a hypovascular tumor measuring 3 cm in diameter in the lateral section.He was diagnosed as having intrahepatic cholangiocarcinoma(ICC), and a left hemihepatectomy was performed in November 2012. During the postoperative follow-up in August 2013, CT revealed swollen lymph nodes around the greater curvature of the stomach and upper edge of the pancreas.By using endoscopic ultrasonography fine-needle aspiration(EUS-FNA), lymph node metastases of the ICC was diagnosed.S -1 monotherapy was initiated instead of gemcitabine and cisplatin regimens because of renal dysfunction.In July 2014, CT revealed that both lymph nodes were shrinking, and in January 2015, S-1 administration was discontinued upon the patient's request.However, the patient survived for 4 years without S-1 administration, and no recurrent tumors were recognized on CT in November 2018.O ur diagnosis indicates complete remission.
