Cure by single modality for advanced hepatocellular carcinoma (HCC) is difficult. Therefore, multidisciplinary approaches are
needed to get a better outcome for advanced HCC. In this paper, we report a case of advanced HCC treated with curative surgical
resection after downstaging by hepatic arterial infusion chemotherapy (HAIC). A 50-year-old male patient had a maximum 16.0
cm sized HCC in the right lobe. He achieved a partial response after 2 cycles of HAIC with 5-FU (750 mg/m2) and cisplatin (25
mg/m2). After completion of 6 cycles, he received a curative right hepatectomy and the histopathology revealed 95% of tumor
necrosis. He is under follow-up without recurrence at 14 months of surgery. This case suggests that surgery after downstaging by
HAIC may provide good clinical outcome in advanced HCC.
