BACKGROUND The tumor biology of hepatocellular carcinoma (HCC) affects recurrence after liver transplantation (LT), but most selection guidelines are based only on tumor size and number. The aim of the study is to evaluate the possibility of expanding the selection criteria in living donor LT (LDLT) without compromising patient survival by adding(More)
OBJECTIVE The limited studies with 18F-fluorodeoxyglucose (18F-FDG)-PET reported results and interpretations that differed between hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (IHCC). We investigated the correlation between preoperative PET results and postoperative prognosis, including early (time-to-recurrence<6 months) tumor(More)
Circulating tumor cells (CTCs) play a major role in the metastasis and recurrence of hepatocellular carcinoma (HCC). Here, we found that major vault protein (MVP) is expressed on the surface of HCC cells and further induced under stressful environments. MVP knockdown reduces cell proliferation and induces apoptosis in HCC cells. Treatment of HCC cells with(More)
Given that retroperitoneal liposarcoma (LPS) is extremely difficult to completely resect, and has a relatively high rate of recurrence, radiotherapy (RT) is the treatment of choice after surgical resection. However, it is difficult to obtain a sufficient radiation field because of the close proximity of surrounding organs. We introduce the use of tissue(More)
A right liver graft with multiple hepatic artery (HA) stumps can be found in approximately 5% of living donor liver transplantation (LDLT) using a right lobe graft. From January 2000 to June 2014, 1149 patients underwent LDLT procedures. Thirty patients with LDLT using a right lobe graft with multiple HA stumps and 149 patients with LDLT using a right lobe(More)
OBJECTIVES The purpose of this study is to identify the safety and feasibility of laparoscopic caudate lobectomy. BACKGROUND Caudate lobectomy has been considered as technically difficult because of the deep location of the caudate lobe and its proximity to great vessels. Due to the technical difficulty, laparoscopic caudate lobectomy was not feasible in(More)
The use of hepatitis B core antibody-positive (HBcAb+) grafts for liver transplantation (LT) has the potential to safely expand the donor pool, as long as proper prophylaxis against de novo hepatitis B (DNHB) is employed. The aim of this study was to characterize the longterm outcome of pediatric LT recipients of HBcAb + liver grafts under a prophylaxis(More)
