AbstractAbstract PDF
Radiofrequency ablation (RFA) is the preferred method of local ablation for patients with small (<3 cm sized) hepatocellular carcinoma (HCC) when surgical resection cannot be applied. If RFA procedure is sufficiently completed, it provides lower local tumor recurrence, and longer overall as well as disease-free survival. We experienced a case of early stage HCC which recurred at 2 months after successful RFA procedure, and rapidly metastasized to lung and brain.

AbstractAbstract PDF
Liver transplantation is curative therapy for hepatocellular carcinoma especially if ,within Milan criteria, 4 year survival and recurrence-free survival was reported to be 85% and 92%, respectively. Herein we report a patient who experience rapid recurrence following living donor liver transplantation (LDLT) for hepatocellular carcinoma within Milan criteria. A 52 year-old-men patient with known liver cirrhosis associated with hepatitis B virus was admitted for the treatment of hepatocellular carcinoma (HCC). Abdominal CT revealed two nodules less than 3 cm in right hepatic lobe. After single session of transcatheter arterial chemoembolization (TACE), the patient underwent LDLT. After seven months following transplantation, recurrent HCC was detected on transplanted liver with concurrent metastatic nodule in lung. Although TACE and metastsectomy were performed for recurrent intrahepatic mass and lung metastasis, recurrent HCC showed rapid progression and patient died of progressive tumor after 10 months following LDLT.

AbstractAbstract PDF
The prognosis of young patients with hepatocellular carcinoma is remains controversial. Here we report a case of advanced hepatocellular carcinoma in twenty, successfully treated with transarterial chemolipidolization (TACL), systemic chemotherapy, radiation therapy and surgical resection. Previously healthy 28 years old woman was admitted for treatment of hepatocellular carcinoma. Abdominal CT showed a diffuse infiltrative HCC involving both lobes with intrahepatic bile duct invasion and pericardial lymphadenopathy. She was treated TAC with systemic chemotherapy and external beam radiotherapy. 6 months after these treatments, main tumor and the pericardial lymph node were decreased in size. And then extended left lobectomy and systemic chemotherapy were done. The pericardial lymph node was markedly decreased. The patient has been followed for 10 months without evidence of regional tumor recurrence.

AbstractAbstract PDF
A 45-year-old man was admitted for the treatment of hepatocellular carcinoma (HCC). He was diagnosed hepatitis B carrier 16 years ago and has not done a routine check. Abdominal CT showed a diffuse infiltrative HCC involving right hepatic lobe with portal vein tumor thrombosis (PVTT) involving right portal vein and proximal portion of left portal vein umbilical portion. With concurrent transcatheter arterial chemotherapy (TAC), helical tomotherapy for portal vein thrombosis was done. With these treatments, main tumor and PVTT was decreased in size markedly and no stain in hepatic angiogram. Due to repeated TAC, hepatic arterial stenosis occurred and TAC was stopped. 3 months after, recurrent tumor was detected in MRI. Radiofrequency ablation followed by High Intensity Focused Ultrasound (HIFU) was done for this recurrent mass. No viable mass was shown in the follow up MRI done 6 months after HIFU.

AbstractAbstract PDF
A 43 year-old-women patient was admitted for one month of jaundice. She was diagnosed hepatitis B carrier 17 years ago and has not done a routine check. Abdominal CT showed a large ill defined mass in left hepatic lobe with inhomogenous enhancement in arterial and delayed phase. The result of biopsy including the immunohistochemical stains showed the combined hepatocellular and cholangiocarcinoma (stage IVa, type C by Allen and Lisa). With the radiation therapy (3,910 cGy), six times of transarterial chemo-lipiodolization and two times of percutaneous ethanol injection, huge mass was markedly decreased in size and no stain in hepatic angiogram. She underwent left lobectomy.

AbstractAbstract PDF
A 64 year-old-male patient was transferred to our hospital for infiltrative hepatocellular carcinoma (HCC) without treatment response because of treatment failure and disease progression. He had been diagnosed infiltrating HCC 9 months ago and then treated with three times of transarterial chemolipiodolization (TACL) in other hospital. But, HCC was progressed. Abdominal CT showed infiltrating HCC in S7 and a small daughter nodule in S8 with right and main portal vein tumor thrombosis (PVTT). We performed stereotatic radiosurgery (Cyberknife) for the treatment of PVTT and four times of TACL for the treatment of intrahepatic HCC every 4weeks. The total radiation doses using with Cyberknife were 36Gy with a prescription isodose 80% in 3 fractions over the three consecutive days. After treatment, infiltrating HCC was decreased in size and PVTT was markedly regressed. Response rate of serum AFP was 57.2%. In conclusion, we report the case of good treatment response in the patient with HCC with PVTT after combination treatment of Cyberknife and TACL.

AbstractAbstract PDF
A 46 year-old male patient was admitted to our hospital for evaluation of hepatic mass which was detected on ultrasonography. He had a history of chronic hepatitis B carrier. Laboratory findings showed that HBsAg was positive, and HBeAg was negative. AFP was 2,081.1 ng/mL. Abdomen CT showed a large well-defined low density lesion involving entire right hepatic lobe which was compatable with advanced hepatocellular carcinoma (stage III). Celiac and hepatic arteriogram reveled huge hypervascular mass at both lobe of the liver. Transcatheter arterial chemoembolization (TACE), systemic chemotherapy, percutaneous ethanol injection therapy (PEIT), and radiotherapy were combined as the treatment of huge hepatoma. After combined therapy, tumor decreased in size. As a result, curative right lobectomy could be performed. Six months after surgery, chest CT showed two small metastatic nodules in both lung, so wedge resection was performed. We followed the patient for 5 years after operation and there was no evidence of regional tumor recurrence or distant metastasis.
