[Trans-Arterial Chemoembolization Therapy for Giant Cholangiocellular Carcinoma - A Single Case Report].

Here, we report a case of cholangiocellular carcinoma that was successfully treated with chemotherapy using a selective intra-arterial infusion technique. A 65-year-old man presented to our hospital to obtain a second opinion regarding his disease. The patient was diagnosed with cholangiocellular carcinoma. The giant tumor was located in the porta hepatis. Some small nodules that were considered to be metastatic lesions were also observed in the surroundingarea. The tumor was judged by the primary physician to be too large for surgical treatment. Consequently, it was decided to treat the patient with trans-arterial chemoembolization(TACE)by selectingintra -arterial infusion of 5-FU, epirubicin(EPI), and mitomycin C prior to EPI-loaded HepaSphere(super-absorbent polymer microsphere)embolization, combined with concurrent systemic gemcitabine chemotherapy. After 5 sessions of the above treatment, the primary lesion reduced dramatically in size. In addition, the levels of CEA and CA19-9 decreased from 34.2 to 2.6 ng/mL and 1,540 to 149 U/mL, respectively. Although the patient's initial life expectancy was only 3 to 6 months, his life expectancy was extended to as longas 26 months followingthe initiation of TACE. This case suggests that treatment with TACE together with systemic chemotherapy can be a powerful therapeutic option for patients with inoperable cholangiocellular carcinoma.
