Hepatocellularcarcinoma

Hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA) constitute highly malignant forms of primary liver cancers. Hepatocellular and bile duct carcinogenesis is a multiplex process, caused by various genetic and epigenetic alterations, the influence of environmental factors, as well as the implication of the gut microbiome, which was undervalued in the previous years. The molecular and immunological analysis of the above malignancies, as well as the identification of the crucial role of intestinal microbiota for hepatic and biliary pathogenesis, opened the horizon for novel therapeutic strategies, such as immunotherapy, and enhanced the overall survival of cancer patients...

BACKGROUND: To assess the values of two elastography techniques combined with serological examination and clinical features in preoperative diagnosis of microvascular invasion in HCC patients. METHODS: A total of 74 patients with single Hepatocellular carcinoma (HCC) were included in this study. Shear wave measurement and real-time tissue elastography were used to evaluate the hardness of tumor-adjacent tissues and tumor tissues, as well as the strain rate ratio per lesion before surgery...

With all the technological progress registered so far, hepatocellular carcinoma is still a diagnostic and therapeutic challenge, the optimal management being ensured only by a personalized attitude, offered by a multidisciplinary approach. Ultrasound plays an essential role in the guidelines for this neoplasm, the intraoperative application being mandatory to increase the survival of these patients, when the surgical approach is possible and indicated. This paper highlights the main indications for intraoperative ultrasound in the diagnosis and treatment of hepatocellular carcinoma, along with areas that have developmental potential...

Hepatectomy is the only potentially curative treatment of hepatic tumors, but remains challenging in case of multiple, bilobar lesions and those located in the vicinity of the hepatic hilum and hepatic veins. Regenerative liver surgery utilizes the unique ability of the liver to re-grow after tissue loss and vascular deprivation. All concepts subsumed under this term aim to increase the resectability of hepatic tumors by stimulating growth of future liver remnant. Many of these techniques have evolved over the last decades...

Intermediate stage hepatocarcinoma, classified b Barcelona Clinic Liver Cancer (BCLC) comprises a large number of patients, with diverse characteristics, being defined by multiple tumours, preserved liver function and good performance status. The recommended treatment for this stage is transarterial chemoembolization (TACE), but there are a few studies that discuss the role of surgery in this stage. We report a case of a 59-year-old woman diagnosed with BCLC B hepatocarcinoma (two tumours of 34 and 25 mm, in liver segments 5 and 6) who was successfully treated with surgical resection...

Combretastatin A-4 (CA-4) received significant interest as a potential anticancer agent in recent years. Several CA-4 analogs were synthesized and investigated to enhance the activity or solve the in vivo decreased activity of CA-4. AIM: The present study aims to investigate the chemotherapeutic and the antiproliferative effects of the mono and the dual therapy of the newly synthesized CA-4 analogs OMA1520 and OMA1774 against hepatocellularcarcinoma (HCC) induced in male adult rats by N-methylnitrosourea (MNU)...

BACKGROUND: Hepatocellularcarcinoma (HCC) metastasis include intrahepatic and extrahepatic metastasis. Similar to intrahepatic metastasis, extrahepatic metastases are not unusual in cases with HCC. However, colonic metastasis is infrequent. CASE REPORT: We describe a clinical case, he was diagnosed with HCC a year ago, treated with TACE (transarterialchemoembolisation), re-examined with abdominal pain and defecation disorder. The tests such as CT scan, colorectal endoscopy, fine needle aspiration (FNA) revealed secondary metastatic lesion of HCC in sigmoid colon...

The main causes of death among patients with Hepatocellularcarcinoma (HCC)are recurrence, metastasis, and deterioration of primary tumors by the epithelial-to-mesenchymal transition (EMT) which is controlled by several molecules including E- and N-cadherin. Micro-ribonucleic acids (miRNAs) have been identified to play a regulatory role in EMT. miR-215 is important in repressingmigration/invasion of cancer cells.In this study, we aimed to evaluate the crosstalk between miR-215 and EMT specific markers (E- and N-cadherin) with a spotlight on its role in the EMT process in HCVinfected patients...

BACKGROUND & AIMS: Fatty liver disease, including non-alcoholic fatty liver (NAFLD) and steatohepatitis (NASH), has been associated with increased intestinal barrier permeability and translocation of bacteria or bacterial products into the blood circulation. In this study, we aimed to unravel the role of both intestinal barrier integrity and microbiota in NAFLD/NASH development. METHODS: C57BL/6J mice were fed with high-fat diet (HFD) or methionine-choline-deficient diet for 1 week or longer to recapitulate aspects of NASH (steatosis, inflammation, insulin resistance)...

AIMS: As a fifth most common cancer type, Hepatocellularcarcinoma (HCC) ranked third leading cause of cancer deaths worldwide. Arsenic trioxide (As2 O3 ) is known as chemotherapeutic agent against few cancer including Acute promyelocyticleukemia and solid tumors. But its effect and possible associated mechanism in HCC is meager. Present study aimed to assess As2 O3 modulatory effect on liver cancer by assessing cell growth and viability. METHODS: Liver normal (Chang liver) and cancerous cells (Hep3B) were exposed to different concentration's (0, 1, 5, 10 & 15 μM) of As2 O3 at different intervals (24, 48 & 72 h)...

miR-223-5p has been demonstrated to regulate the development and progression of various cancers, such as hepatocellular carcinoma, breast cancer, and gastric carcinoma. However, the role of miR-223-5p in non-small cell lung cancer (NSCLC) requires further investigation. In this study, we found that the expression of miR-223-5p was significantly downregulated in NSCLC tissues and cell lines. Moreover, the expression level of miR-223-5p is negatively correlated with the malignance of NSCLC. We found that overexpression of miR-223-5p remarkably suppressed the proliferation of NSCLC cells in vitro and in vivo...

Liver fibrosis is a disease that causes high morbidity and has become a major health problem. Liver fibrosis can lead to the end stage of liver diseases (livercirrhosisand hepatocellularcarcinoma). Currently, liver transplantation is the only effective treatment for end-stage liver disease. However, the shortage of organ donors, high cost of medical surgery, immunological rejection and transplantation complications severely hamper liver transplantation therapy. Mesenchymal stem cells (MSCs) have been regarded as promising cells for clinical applications in stem cell therapy in the treatment of liver diseases due to their unique multipotent differentiation capacity, immunoregulation and paracrine effects...

INTRODUCTION: Liver resection in cirrhotic patients is associated with increased morbidity and mortality. The objective of this study was to compare short-term results of laparoscopic resection (LR) and open surgery (OS) for minor liver resection in patients with hepatocellular carcinoma (HCC) hepatocellularcarcinoma on nontumor cirrhotic liver (HCC/F4) and patients with colorectal cancer liver metastases (CRLMs) colorectal liver metastases on healthy liver (CRLM/F0). MATERIALS AND METHODS: Between January 2005 and December 2014, all patients undergoing liver resection (n = 754) were included in this study...

Immunosuppression is a significant factor in the progression of tumor invasion and metastasis. Melatonin, a well-known hormone, has certain cytotoxic and immune regulatory effects to inhibit tumor function. Exosomes are small membrane vesicles released by many kinds of cells, which contain different macromolecules, such as mRNAs and microRNAs (miRNAs), and proteins that can mediate communications between cells. Tumor-derived exosomes may cause immunosuppression, however, it is unknown whether melatonin can attenuate an immunosuppressive status by altering the function of tumor-derived exosomes...

BACKGROUND: Ultrasonography (US) is widely used as a standard surveillance tool for patients who are at a high risk of having hepatocellular carcinoma (HCC); however, conventional B-mode US appears to be insufficient in order to ensure the early detection of HCC. Perfluorobutane allows very stable Kupffer phase imaging for at least 60 min, which is tolerable for examinations of the entire liver. The purpose of our study is to evaluate the added value of contrast-enhanced US using perfluorobutane to that of conventional B-mode US as an HCC surveillance tool for patients with liver cirrhosis...

BACKGROUND/AIM: The Mdr2(-/-) mouse develops early chronic cholestatic hepatitis and hepatocellularcarcinoma (HCC) when adult. We tested the effects of a restricted-calorie diet on HCC development in Mdr2(-/-) mice. MATERIALS AND METHODS: Mdr2(-/-) mice (n=40, divided into two groups of 20 mice each) were randomized to receive ad libitum diet or restricted-calorie diet. Two mice from each group were sacrificed at 3 and 6 months, and liver tissue samples were removed for analysis...

Deregulated c-Myc expression is a hallmark of many human cancers. We have recently identified a role of mammalian homolog of yeast SPT-ADA-GCN5-acetyltransferas (SAGA) complex component, SAGA-associated factor 29 (SGF29), in regulating the c-Myc overexpression. Here, we discuss the molecular nature of SFG29 in SPT3-TAF9-GCN5-acetyltransferase complex, a counterpart of yeast SAGA complex, and the mechanism through which the elevated SGF29 expression contribute to oncogenic potential of c-Myc in hepatocellularcarcinoma (HCC)...

Adoptive transfer of lymphocytes expressing engineered T cell receptors (TCR) is a promising option for cancer treatment and could include hepatocellularcarcinoma (HCC), where therapeutic options are limited. We have recently investigated whether hepatitis B viral antigens can act as a HCC-specific antigen and thus be targeted by adoptively transferred HBV-specific TCR redirected T cells.

Cholangiocarcinoma (CCA) is the second most common-primary liver cancer. The difficulties in diagnosis limit successful treatment of CCA. At present, histological investigation is the standard diagnosis for CCA. However, there are some poor-defined tumor tissues which cannot be definitively diagnosed by general histopathology. As molecular signatures can define molecular phenotypes related to diagnosis, prognosis, or treatment outcome, and CCA is the second most common cancer found after hepatocellularcarcinoma (HCC), the aim of this study was to develop a predictive model which differentiates CCA from HCC and normal liver tissues...

Peroxiredoxin 1 (PRDX1) is a member of the peroxiredoxin family. Aberrant expression of PRDX1 has been described in various cancers. We investigated the significance of this up-regulation in non-challenged hepatocellularcarcinoma (HCC) cells by establishing a HepG2 cell line stably expressing a Prdx1 shRNA. Prdx1 silencing reversed, at least partially, the tumoural phenotype of HepG2 cells, resulting in morphological changes, delayed cell growth, down-regulation of transcripts for AFP, osteopontin and β-catenin and decreased γ-glutamyl transpeptidase activity, and oppositely up-regulation of transcripts for E-cadherin and proapoptotic proteins (BAX, CASP3) and increased alkaline phosphatase and CASP3 activities...
