The patient was a 63-year-old man with hepatitis C. He discontinued combination therapy containing interferon and ribavirin because of the development of skin symptoms. A screening examination showed multiple early-stage hepatocellular carcinomas. He refused treatment and was followed up as an outpatient. During follow-up, his PIVKA-Ⅱ level remarkably elevated to 59,994mAU/mL. Computed tomography(CT)showed an enlarged tumor with portal invasion(vp2)in segment 8 and intrahepaticmetastasis. We performed right and partial hepatectomy...

We encountered a case of hepatic portal lymph node metastasis after repeated treatment for hepatocellular carcinoma (HCC)recurrence. A 73-year-old male patient underwent partial gastrectomy following rupture of a gastrointestinal stromal tumor 8 years ago. A 70mm tumor was simultaneously revealed in the posterior segment of the liver, and imatinib treatment was initiated based on the diagnosis of a metastatic liver tumor. Due to the absence of an increasing tendency in the tumor, extended posterior segmentectomy was performed, and the pathological diagnosis was moderately differentiated HCC...

We report a case of pathologicallycomplete response in ruptured hepatocellular carcinoma(HCC)treated with transcatheter arterial embolization(TAE). A 56-year-old man presented to our hospital with a hepatic tumor. Enhanced computed tomography(CT)revealed a tumor 65mm in diameter at S7/8 of the liver and the presence of abdominal fluid collection around the tumor. We diagnosed rupture of HCC and selective TAE was subsequentlyperformed. After TAE, the elevated PIVKA- / Ⅱ tumor marker level(1,008mAU/mL)decreased to the normal level...

Laminin (Ln)-332 consists of α3, β3, and γ2 chains, which mediate epithelial cell adhesion to the basement membrane. Ln-γ2, a component of Ln-332, is frequently expressed as a monomer in the invasion front of several types of malignant tissues without simultaneous expression of Ln-α3 and/or Ln-β3 chains. Moreover, monomeric Ln-γ2 induces tumor cell proliferation and migration in vitro. These unique biological activities indicate that monomeric Ln-γ2 could be a candidate biomarker for early cancer surveillance...

INTRODUCTION: Vitamin K plays an important role in blood coagulation. Diet is the main source of vitamin K and body stores are depleted in days, hence deficiency is common in malnourished older people. A high proportion of people who sustain a hip fracture are already malnourished, compounded by fasting for surgery which might further increase deficiency. We wanted to explore the prevalence of vitamin K deficiency in hip fracture patients and the impact of a short period of fasting. METHODS: In consecutive patients hospitalised with a hip fracture, we measured vitamin K and PIVKA-II (undercarboxylated factor II - a marker of subclinical vitamin K status) on admission and on first post-operative day...

AIM: There is no evidence indicating that survival improvement is associated with anatomical laparoscopic liver resection (ALLR) rather than non-ALLR (NALLR) to treat solitary hepatocellular carcinoma (HCC). The aim of our study was to compare the oncological outcomes of ALLR versus NALLR. MATERIALS AND METHODS: From January 2008 to September 2014, 231 patients underwent LLR as the primary treatment for solitary HCC without portal vein tumor thrombus. After matching one-to-one propensity scores, 118 patients were included in 2 groups: NALLR (n = 59) and ALLR (n = 59)...

BACKGROUND: The prognosis of hepatocellular carcinoma (HCC) with tumor thrombus in the major portal vein (PV) is extremely poor. The purpose of this study was to clarify the impact of hepatic resection for HCC with tumor thrombus in the major PV. PATIENTS: Four hundred patients undergoing macroscopic curative resection for HCC involving the first branch or trunk of the PV between 2001 and 2010 at the 22 institutions were enrolled. We examined the effect of adjuvant hepatic arterial infusion chemotherapy (HAIC) on prognosis and validated the prognostic index consisting of ascites, prothrombin activity, and maximal tumor diameter...

BACKGROUND/AIM: High mobility group box-1 (HMGB1) induces the release of proinflammatory cytokines and chemokines as a late-acting mediator of inflammation. Hepatocellular carcinoma (HCC) is a typical inflammation-related cancer. However, little is known about the relationship between HCC and HMGB1 and its receptor RAGE (receptor for advanced glycation end products). This study analyzes the clinicopathological relevance of HMGB1 expression level and the effect of HMGB1 expression on the characteristics of HCC...

Although the number of reports describing tumors in aged NHP has increased, spontaneous neoplasias in NHP are extremely rare, with the notable exception of prosimians, in which spontaneous hepatic neoplasms arise. In addition to radiography and ultrasonography, superparamagnetic iron oxide (SPIO)-enhanced MRI tends to be applied in human practice to non-invasively locate, identify, and size liver tumors and to define the border between neoplastic and normal tissues. Here we report a 13-y-old female cynomolgus monkey with anorexia and serologically normal liver enzymes...

BACKGROUND: Vitamin K (VK) is a co-factor of the γ-glutamyl carboxylase that catalyzes the conversion of glutamate residues to γ-carboxyglutamate in VK-dependent proteins. The carboxylation reaction imparts the essential calcium-binding residues for the biological function of several proteins involved in the process of coagulation and bone metabolism. VK deficiency is frequently encountered in newborns and can lead to fatal hemorrhagic complications. This review describes and discusses the clinical application of VK deficiency testing...

Introduction: Pseudoxanthoma elasticum (PXE) is a rare disease caused by mutations in the ABCC6 gene. Vitamin K1 is involved in the posttranslational carboxylation of some proteins related to inhibition of the calcification process. Our aim was to investigate, in patients affected by PXE, baseline levels of vitamin K1 -dependent proteins and -metabolites and whether parenteral administration of phytomenadione was effective in modulating their levels. Methods: We included eight PXE patients with typical clinical symptoms (skin, retina, and vascular calcification) and two ABCC6 causative mutations; 13 clinically unaffected first-degree patients' relatives (9 carrying one ABCC6 mutation and 4 non-carriers)...

Protein induced by vitamin K absence or antagonist-II (PIVKA-II), an abnormal form of prothrombin, is used as a serological biomarker that aids in the diagnosis of hepatocellular carcinoma (HCC). PIVKA-II is typically measured by liquid binding assay (LiBA). However, without an internal standard, it is difficult to obtain accurate results. Thus, we aimed to develop a selected reaction monitoring-mass spectrometry (SRM-MS)-based assay to quantify PIVKA-II in serum. Our SRM-MS assay entailed the addition of a protein analog as an internal standard, the enrichment of PIVKA-II using a monoclonal antibody, chymotrypsin digestion, online desalting, and SRM-MS analysis...
