Abstract 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.

Treatment of Massive Hepatocellular Carcinoma with Portal Vein Invasion: Jung Hyun Kwon, Jong Young Choi, Jin Dong Kim, Hyun Young Woo, Si Hyun Bae, Seung Kew Yoon, Young Jun Lee, Ho Jong Chun; Journal of the Korean Liver Cancer Study Group. 2009;9(1):53-58. Published online June 30, 2009

Abstract PDF: A 52 year-old-man patient was admitted for evaluation of hepatic mass which was detected on screening ultrasonography. His abdominal CT showed a massive infiltrating mass in left hepatic lobe and another 2.4 cm nodule in S6 of Rt. Hepatic lobe with arterial enhancement and rapid wash out underlying liver cirrhosis. Also, low density tumor thrombus are filled in Lt. portal vein and extended into main portal vein. He was finally diagnosed HCC (UICC stage IVa) with liver cirrhosis (Child-Pugh class A) and hepatitis B. With the four times of trasnarterial chemo-lipiodolization and seven times of intraarterial infusion chemotherapy for huge mass and one time Radiofrequency ablation (RFA) for daughter nodule, his HCC showed no stain in hepatic angiogram at nine month from initial diagnosis. After additional eight times of intra-arterial infusion chemotherapy, new small nodule developed in S6 and was ablated with RFA. At eighteen months after initial diagnosis, he shows no viable lesion on the imaging study and tumor markers are normalized.

A Case of the Complete Remission of a Solitary Extrahepatic Bile Duct Hepatocellular Carcinoma without Primary Hepatic Parenchymal Lesions by Cyberknife Treatment: Soung Won Jeong, Si Hyun Bae, Hyun Young Woo, Chan Ran You, Won Hang Hur, Jong Young Choi, Seung Kew Yoon, Dong Hoon Lee, Young Jun Lee, Jae Young Byun, Hong Seok Jang; Journal of the Korean Liver Cancer Study Group. 2008;8(1):92-97.

Abstract PDF: A 69-year-old man patient was hospitalized by confused mentality. He had chronic hepatitis B virus infection and was diagnosed with liver cirrhosis 20 years ago. Abdominal CT showed about 2×1 cm sized polypoid mass with mild arterial enhancement at the S4 of liver, causing moderate dilatation of the left IHBD. In the CTHA-AP, intraductal mass was hyperattenuated at arterial phase and washed out at portal phase. Celiac angiography revealed nodular tumor staining correlating to intraductal mass on CT. In MRCP and ERCP, a polypoid lesion was noted at the orifice of left main intrahepatic duct. The patient was treated with cyber-knife for 3 days with 3600 cGy. In follow up CT after 2 month of cyber-knife treatment, there was regression of previously noted left IHBD dilatation and no definite enhancing intraductal mass.

A Case of Advanced Hepatocellular Carcinoma with Portal Vein Tumor Thrombosis Achieving Complete Response with New Therapeutic Modalities: Hyun Young Woo, Jin Dong Kim, Jung Hyun Kwon, Chan Ran You, Jeong Won Jang, Si Hyun Bae, Jong Young Choi, Se Hyun Cho, Seung Kew Yoon, Dong Hoon Lee, Ho Jong Chun, Byung Gil Choi, Chul Seung Kay; Journal of the Korean Liver Cancer Study Group. 2008;8(1):124-127.

Abstract 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.

A Case of Cyberknife Treatment for Hepatocellular Carcinoma with Portal Vein Tumor Thrombosis: Chan Ran You, Si Hyun Bae, Hyun Young Woo, Soung Won Jeong, Jong Young Choi, Seung Kew Yoon, Hong Seok Jang, Dong Hoon Lee, Byung Gil Choi; Journal of the Korean Liver Cancer Study Group. 2007;7(1):82-86.

Abstract 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.
