    Sorafenib from palliative to neoadjuvant chemotherapy in hepatocellular carcinoma with major vascular invasion: experience of two cases

    Naganathan Selvakumar , Sandeep Vohra , Deep Sika Arora , Subash Gupta
    Hepatocellular carcinoma (HCC) is the fifth most common malignancy worldwide and the incidence is higher in cirrhosis. Treatment options depend on tumor stage, status of liver function, and the general condition of the patient. Major vascular invasion is a contraindication for liver transplantation. Sorafenib has been found to be useful in association with transarterial chemoembolization as an effective chemotherapeutic agent to prolong survival in inoperable HCCs. Here we describe our experience where sorafenib was used as palliation but...

    Radiological diagnosis of hepatocellular carcinoma in non-cirrhotic patients

    Alba Castán , Ylenia Navarro , Luis Sarría , Raquel Larrosa , Mario Serradilla , Alejandro Serrablo
    Hepatocellular carcinoma (HCC) arising in non-cirrhotic livers is relatively rare. Compared with HCC arising in cirrhotic livers they have some quirks. HCC in healthy livers are large tumors at diagnosis, and are detected due to the onset of abdominal symptoms, outside of any scheduled monitoring program. In non-cirrhotic patients, HCC has the same appearance as the classic image of cirrhotic HCC substrate. The presence of capsule, extensive intratumoral necrosis and typical behavior in the dynamic study after administration of intravenous...

    Evaluating normalization approaches for the better identification of aberrant microRNAs associated with hepatocellular carcinoma

    Jing Shen , Qiao Wang , Irina Gurvich , Helen Remotti , Regina M. Santella
    Aim: Dysregulated microRNAs (miRNAs) have been identified in hepatocellular carcinoma (HCC), but only a small proportion have been confirmed. An appropriate normalizer is crucial to determining the accuracy and reliability of data from miRNA studies. Methods: Different normalization strategies were used to validate genome-wide miRNA profiles in HCC tumor and non-tumor tissues, and to determine the consistency and discrepancy of data on dysregulated miRNAs. Results: Two sets of stable miRNAs (miR-30c/miR-30b and miR-30c/miR-126) were...

    Hepatitis B virus molecular biology and pathogenesis

    R. Jason Lamontagne , Sumedha Bagga , Michael J. Bouchard
    As obligate intracellular parasites, viruses need a host cell to provide a milieu favorable to viral replication. Consequently, viruses often adopt mechanisms to subvert host cellular signaling processes. While beneficial for the viral replication cycle, virus-induced deregulation of host cellular signaling processes can be detrimental to host cell physiology and can lead to virus-associated pathogenesis, including, for oncogenic viruses, cell transformation and cancer progression. Included among these oncogenic viruses is the hepatitis B...

    Preoperative liver functional volumetry performed by 3D-99mTc-GSA scintigraphy/vascular fusion imaging using SYNAPSE VINCENT: a preliminary study

    Hiroshi Yoshida , Hiroshi Makino , Tadashi Yokoyama , Hiroshi Maruyama , Atsushi Hirakata , Junji Ueda , Yasuhiro Mamada , Nobuhiko Taniai , Eiji Uchida
    Aim: The present study was designed to evaluate the feasibility of preoperative liver functional volumetry performed by 3D-technetium-99m-diethylenetriaminepentaacetic acid-galactosyl-human serum albumin (99mTc-GSA) scintigraphy/vascular fusion imaging using SYNAPSE VINCENT and to examine the discrepancy between conventional and functional volumetry. Methods: The study group comprised 15 patients who underwent preoperative 3-dimensional (3D)-99mTc-GSA scintigraphy/vascular fusion imaging using SYNAPSE VINCENT software before hepatectomy...

    Physiological potential of cytokines and liver damages

    Fathia A. Mannaa , Khaled G. Abdel-Wahhab
    Cytokines are soluble extracellular small molecular weight protein or peptide. They are produced by virtually every nucleated cell type in response to injurious stimuli to control body metabolism, infection, inflammation and tissue or neuronal damage; therefore acting as messengers between tissues and the immune system; and participating in many physiological processes through their either anti-inflammatory or pro-inflammatory characteristics. Many cytokines have multiple cellular sources and targets, as well as many natural inducers and...

    Identifying microRNA panels specifically associated with hepatocellular carcinoma and its different etiologies

    Jing Shen , Abby B. Siegel , Helen Remotti , Qiao Wang , Regina M. Santella
    Aim: Deregulation of microRNAs (miRNAs) expression has been identified in hepatocellular carcinoma (HCC), but few results are consistent. The objective of this study is to investigate “HCC tumor type specific” and “tumor common” miRNA panels. Methods: The authors integrate and analyze clinical, etiologic and miRNA profiles data from 9 types of solid tumors in The Cancer Genome Atlas (TCGA) and HCC data from Columbia University Medical Center (CUMC). Results: Levels of 33 miRNAs were significant different between HCC tumor and paired...

    Role of antiviral therapy in patients with chronic hepatitis B or C virus in preventing the development of hepatocellular carcinoma

    Laura Scribano , Veronica Vanin , Giorgia Gottardo , Diana Sacchi , Francesco Paolo Russo
    Patients with chronic hepatitis B virus (HBV) and hepatitis C virus (HCV) infection are at significant risk for hepatocellular carcinoma (HCC). The most important risk factor associated with HCC is liver cirrhosis, which is again predominantly caused by chronic HBV or HCV infection. The most effective approach to avoid HCC development is to prevent HBV and HCV infection through vaccination. Indeed, HBV vaccine is the first vaccine demonstrated to prevent cancers. However, a vaccine for HCV is not available. Thus, the prevention of HCV-related...

    Association of serum levels of epidermal growth factor with disease severity in patients with unresectable hepatocellular carcinoma

    Mohamed Ahmed Samy Kohla , Om Kolsoum Al-Haddad , Ali Nada , Mohamed Al-Warraky , Manar Obada , Mohamed Amer , Sameera Ezzat , Ashraf Abou Gabal
    Aim: Epidermal growth factor (EGF) is a mitogen for hepatocyte grown in vitro, and its expression is up-regulated during liver regeneration. EGF also plays an important role in tumor initiation and progression. The goal of this study is to assess whether EGF is associated with advanced hepatocellular carcinoma (HCC) and also whether it is a predictive factor of shortened survival. Methods: Serum EGF levels were evaluated in a total of 151 subjects: 51 patients with unresectable HCC, (21 of them were eligible for transarterial...

    Aqueous extract of Corchorus olitorius decreases cytotoxicity of aflatoxin B1 and fumonisin B1 in H4IIE-luc cells

    Mohamed I. M. Ibrahim , Rialet Pieters , Sekena H. Abdel-Aziem , Anna M. van der Walt , Cornelius C. Bezuidenhout , John P. Giesy , Mosaad A. Abdel-Wahhab
    Aim: Afl atoxin B1 (AFB1) and fumonisin B1 (FB1) are important food-borne mycotoxins. Co-contamination of foodstuffs with these two mycotoxins is well-known and has been implicated in a possible development of hepatocellular carcinoma in humans living in regions of the world where exposures to these mycotoxins in grain are greatest. The aim of the current study was to evaluate the potential protective effects of an aqueous extract of Cochorus olitorius (C. olitorius, moroheiya) against cytotoxicity of AFB1 and/or FB1 in H4IIE-luc rat...
