[A case of curatively resected advanced intrahepatic cholangiocellular carcinoma through effective response to neoadjuvant chemotherapy].

A 67-year-old-man came to our hospital for further evaluation of a liver tumor detected by abdominal ultrasonography at another hospital. Abdominal computed tomography showed a tumor (8 cm in diameter)in the left lobe of the liver, with invasion of the left and middle hepatic veins, and multiple lymph node metastases. Liver biopsy examination revealed intrahepatic cholangiocellular carcinoma (cStage IVB). Therefore, chemotherapy with gemcitabine(GEM)was administered. The hepatic tumor and multiple lymph nodes were reduced in size after eight courses of GEM chemotherapy. In May 2013, we performed an extended left hepatectomy with biliary tract reconstruction and extended lymph node dissection. The histological diagnosis was intrahepatic cholangiocellular carcinoma, pT3N0H0P0M (-), fStage III. The patient's postoperative recovery was good, and 1 month after surgery, the patient received 6 course of postoperative adjuvant GEM chemotherapy. No serious adverse events occurred during the postoperative adjuvant therapy period. The patient is alive without recurrence 14 months after surgery and 23 months after diagnosis.
