    Colorectal cancer is the second most common type of cancer in industrialized countries. Despite improved resection procedures and optimized adjuvant chemotherapy, local or distant recurrences occur in 22-25% of patients with stage II/III colon cancer. Approximately 30% of patients have advanced disease at presentation. The liver is the most common site of colorectal metastases and, interestingly, 20-30% of patients with colorectal cancer have liver-only metastases. The combined modality of chemotherapy and surgery increases overall survival and the chance of cure for metastatic patients, even if there is no agreement in terms of the best schedule and how long the treatment must last. In this paper, we review the role and the rationale of neoadjuvant chemotherapy within a multimodal approach, and discuss remaining questions and future directions.

    Colorectal cancer (CRC) is one of the leading causes of cancer-related death. Surgery, radiotherapy and chemotherapy have been till now the main therapeutic strategies for disease control and improvement of the overall survival. Twenty-five per cent (25%) of CRC patients have clinically detectable liver metastases at the initial diagnosis and approximately 50% develop liver metastases during their disease course. Twenty-thirty per cent (20%-30%) are CRC patients with metastases confined to the liver. Some years ago various studies showed a curative potential for liver metastases resection. For this reason some authors proposed the conversion of unresectable liver metastases to resectable to achieve cure. Since those results were published, a lot of regimens have been studied for resectability potential. Better results could be obtained by the combination of chemotherapy with targeted drugs, such as anti-VEGF and anti-EGFR monoclonal antibodies. However an accurate selection for patients to treat with these regimens and to operate for liver metastases is mandatory to reduce the risk of complications. A multidisciplinary team approach represents the best way for a proper patient management. The team needs to include surgeons, oncologists, diagnostic and interventional radiologists with expertise in hepatobiliary disease, molecular pathologists, and clinical nurse specialists. This review summarizes the most important findings on surgery and systemic treatment of CRC-related liver metastases. PMID:27621569

    The contents of 15 trace elements in the sera of 30 liver cancer patients and 30 healthy adults were assayed by ICP-AES method. The data obtained were analysed by routine statistical tests, multi-variate discrimination analysis, multi-variate stepwise regression analysis and non-linear mapping algorithm. The results showed that the contents of copper, vanadium, cadmium, stannum, cobalt, nickel in liver cancer patients were significantly higher than those in healthy adults. The serum trace element spectrum of liver cancer patients was different from that of healthy adults. Hence, the liver cancer patients could be differentiated from healthy adults by serum trace element spectrum. PMID:2249593

    We aimed to determine the factors predicting liver cirrhosis-related complications in the early postoperative period after lung cancer surgery in patients with liver cirrhosis. We retrospectively reviewed the medical records of patients who underwent curative surgery for primary lung cancer in our institute from January 1990 to March 2007, finding 37 cases with comorbid liver cirrhosis. These patients were divided into two groups, according to whether liver failure, bleeding, and critical infection had occurred postoperatively. Various clinical parameters were analyzed statistically between the bigeminal groups. Liver cirrhosis-related complications occurred in seven of the 37 patients (18.9%). Transient liver failure occurred in two patients (5.4%) after pulmonary resection. Acute intrathoracic bleeding occurred in four cases (10.8%). Two patients died (5.4%) in both cases due to sepsis. Preoperative total bilirubin (P<0.05), and indocyanine green retention rate at 15 min (P<0.05) were significantly higher in patients with liver failure. Only serum value of total bilirubin was an independent risk factor (P<0.05) by multivariate analysis. In predicting death from infection, only preoperative nutritional status was a significant risk factor (P<0.05). To avoid postoperative cirrhosis-related complications, preoperative preparation to improve their liver function and nutrition status is essential. PMID:17766277

    Objective: The prevalence of diabetes mellitus (DM), impaired glucose tolerance (IGT) and impaired fasting glucose (IFG) were hypothesised to be different among different tumor patients. This study aimed to study the association between the prevalence of DM, IGT and IFG and liver cancer, colorectal cancer, breast cancer, cervical cancer, nasopharyngeal cancer and benign tumor. Methods:  A hospital based retrospective study was conducted on 4610 patients admitted to the Internal Medical Department of the Affiliated Tumor Hospital of Guangxi Medical University, China. Logistic regression was used to examine the association between gender, age group, ethnicity , cancer types or benign tumors and prevalence of DM, IFG, IGT. Results: Among 4610 patients, there were 1000 liver cancer patients, 373 breast cancer patients, 415 nasopharyngeal cancer patients, 230 cervical cancer patients, 405 colorectal cancer patients, and 2187 benign tumor patients. The prevalence of DM and IGT in liver cancer patients was 14.7% and 22.1%, respectively. The prevalence of DM and IGT was 13.8% and 20%, respectively, in colorectal cancer patients, significantly higher than that of benign cancers. After adjusting for gender, age group, and ethnicity, the prevalence of DM and IGT in liver cancers patients was 1.29 times (CI :1.12-1.66) and 1.49 times (CI :1.20-1.86) higher than that of benign tumors, respectively. Conclusion: There was a high prevalence of DM and IGT in liver cancer patients.

    The aim of this study is to provide a diagnostic performance evaluation of contrast-enhanced ultrasonography (CEUS) in detecting liver metastases in patients with suspected of pancreatic or periampullary cancer. Computed tomography (CT) is often insufficient for detection of liver metastases, but their presence plays a crucial role in the choice of therapy. Eighty-nine patients with suspected pancreatic or periampullary cancer were included in this prospective study with retrospective analysis. Patients underwent an abdominal CT and CEUS. Fifteen patients had liver metastases. The CT sensitivity was 73.3% (11/15), the specificity 93.2% (69/74), the positive predictive value (PPV) 68.8% (11/16) and the negative predictive value (NPV) 94.6% (69/73). Based on CEUS, the sensitivity was 80% (12/15), specificity 98.6% (73/74), PPV 92.3% (12/13) and NPV 96.1% (73/76). CEUS improved characterization of liver lesions in patients with suspected pancreatic or periampullary cancer compared with CT. CEUS can better detect benign liver lesions and distinguish false-positive or indeterminate CT results.

    The objective of this study is to correlate the presence of bone and liver metastases in patients with breast cancer with respect to the results of bone and liver scans, axillary nodal status, and serum alkaline phosphatase levels. One hundred ninety-seven patients with breast cancer treated by modified radical mastectomy between the years 1978 and 1981 were studied. Fifty-nine (30%) of the total group had distant metastases during the course of observation of 60 to 96 months; of 35 patients in whom bone metastases developed, 30 had normal preoperative bone scan results. Of 21 patients who had liver metastases, 19 had normal preoperative liver scans. Nineteen (70%) of the 27 patients with abnormal bone scans had normal alkaline phosphatase levels. Seven (63%) of the 11 patients who had abnormal liver scans had a normal alkaline phosphatase. The study supports the concept that preoperative bone and liver scans are ineffective indicators of metastatic involvement. Selection of patients for screening by bone and liver scans according to alkaline phosphatase determinations was not supported by this study. The appropriate use of bone scans for screening in patients with breast carcinoma is suggested as a follow-up device in patients with positive lymph nodes.

    The aim of the present study was to compare the levels of essential trace and toxic elements in biological samples (blood and serum) of male liver cirrhotic/cancer patients (n = 144), of age groups 30-50 years, before and after 60 days treatment with mineral supplementation. For comparison purposes, the same biological samples were also collected from healthy male subjects (n = 120) of the same age groups. The biological samples were oxidized by 65 % HNO₃/30 % H₂O₂ (2:1) in a microwave oven. The digests of all biological samples were analyzed for arsenic (As), cadmium (Cd), selenium (Se), and zinc (Zn) by electrothermal atomic absorption spectrometry. The levels of Se and Zn were lower in liver cirrhotic/cancer patients as compared to healthy individuals (p < 0.001). The patients with liver cirrhosis/cancer have twofold higher As and Cd levels in biological samples as compared to age-matched referents. Moreover, a negative correlation was observed between essential and toxic elements. The pathogenesis of liver cirrhosis/cancer has been associated with changes in the balance of certain essential trace and toxic elements. The study confirms that oral supplements of Se and Zn produce metabolic effects in patients with liver cirrhosis/cancer. It was observed that the status of essential trace elements, Se and Zn, was improved in biological samples of all patients after 60 days of treatment with mineral supplementation.

    Because of its advantageous depth-dose relationship, proton radiotherapy is an emerging treatment modality for patients with liver cancer. Although the proton dose distribution conforms to the target, healthy tissues throughout the body receive low doses of stray radiation, particularly neutrons that originate in the treatment unit or in the patient. The aim of this study was to calculate the effective dose from stray radiation and estimate the corresponding risk of second cancer fatality for a patient receiving proton beam therapy for liver cancer. Effective dose from stray radiation was calculated using detailed Monte Carlo simulations of a double-scattering proton therapy treatment unit and a voxelized human phantom. The treatment plan and phantom were based on CT images of an actual adult patient diagnosed with primary hepatocellular carcinoma. For a prescribed dose of 60 Gy to the clinical target volume, the effective dose from stray radiation was 370 mSv; 61% of this dose was from neutrons originating outside of the patient while the remaining 39% was from neutrons originating within the patient. The excess lifetime risk of fatal second cancer corresponding to the total effective dose from stray radiation was 1.2%. The results of this study establish a baseline estimate of the stray radiation dose and corresponding risk for an adult patient undergoing proton radiotherapy for liver cancer and provide new evidence to corroborate the suitability of proton beam therapy for the treatment of liver tumors.

    Undetected micrometastasis plays a key role in the metastasis of cancer in colorectal cancer (CRC) patients. The aim of this study is to identify a biomarker of CRC patients with liver metastasis through the detection of circulating tumor cells (CTCs). Microarray and bioinformatics analysis of 10 CRC cancer tissue specimens compared with normal adjacent tissues revealed that 31 genes were up-regulated (gene expression ratio of cancer tissue to paired normal tissue > 2) in the cancer patients. We used a weighted enzymatic chip array (WEnCA) including 31 prognosis-related genes to investigate CTCs in 214 postoperative stage I-III CRC patients and to analyze the correlation between gene expression and clinico-pathological parameters. We employed the immunohistochemistry (IHC) method with polyclonal mouse antibody against DVL1 to detect DVL1 expression in 60 CRC patients. CRC liver metastasis occurred in 19.16% (41/214) of the patients. Using univariate analysis and multivariate proportional hazards regression analysis, we found that DVL1 mRNA overexpression had a significant, independent predictive value for liver metastasis in CRC patients (OR: 5.764; 95% CI: 2.588-12.837; p < 0.0001 on univariate analysis; OR: 3.768; 95% CI: 1.469-9.665; p = 0.006 on multivariate analysis). IHC staining of the immunoreactivity of DVL1 showed that DVL1 was localized in the cytoplasm of CRC cells. High expression of DVL1 was observed in 55% (33/60) of CRC tumor specimens and was associated significantly with tumor depth, perineural invasion and liver metastasis status (all p < 0.05). Our experimental results demonstrated that DVL1 is significantly overexpressed in CRC patients with liver metastasis, leading us to conclude that DVL1 could be a potential prognostic and predictive marker for CRC patients.

    Pancreatic cancer patients underwent surgical resection often present distant metastases early after surgery. Detection of circulating tumor cells (CTCs) has been correlated to a worse oncological outcome in patients with advanced pancreatic cancer. The objective of this pilot study is to investigate the possible prognostic role of CTCs in patients undergoing surgery for pancreatic cancer. In 20 patients undergoing pancreatic resection, 10 mL blood sample was collected intraoperatively from both systemic circulation (SC) and portal vein (PV). Blood sample was analyzed for CTCs with CellSearch® system. All patients underwent an oncologic follow-up for at least 3 years, quarterly. CTCs were detected in nine (45%) patients: five patients had CTCs in PV only, three patients in both SC and PV, and one patient in SC only. CTC-positive and CTC-negative patients were similar for demographics and cancer stage pattern. No significant differences were found in both overall and disease-free survival between CTC-positive and CTC-negative patients. At 3-year follow-up, portal vein CTC-positive patients presented a higher rate of liver metastases than CTC-negative patients (53 vs. 8%, p = 0.038). CTCs were found in 45% of the patients. No correlation between CTCs and survival was found. The presence of CTCs in portal vein has been associated to higher rate of liver metastases after surgery.

    Objective Venous thromboembolism (VTE) may be a marker of occult cancer in the general population. While liver disease is known to increase the risk of VTE and cancer, it is unclear whether VTE in patients with liver disease is also a marker of occult cancer. Design A population-based cohort study. Setting Denmark. Participants We used population-based health registries to identify all patients with liver disease in Denmark with a first-time diagnosis of VTE (including superficial or deep venous thrombosis and pulmonary embolism) during 1980–2010. Patients with non-cirrhotic liver disease and patients with liver cirrhosis were followed as two separate cohorts from the date of their VTE. Measures For each cohort, we computed the absolute and relative risk (standardised incidence ratio; SIR) of cancer after VTE. Results During the study period, 1867 patients with non-cirrhotic liver disease and 888 with liver cirrhosis were diagnosed with incident VTE. In the first year following VTE, the absolute risk of cancer was 2.7% among patients with non-cirrhotic liver disease and 4.3% among those with liver cirrhosis. The SIR for the first 90 days of follow-up was 9.96 (95% CI 6.85 to 13.99) among patients with non-cirrhotic liver disease and 13.11 (95% CI 8.31 to 19.67) among patients with liver cirrhosis. After 1 year of follow-up, SIRs declined, but remained elevated in patients with non-cirrhotic liver disease (SIR=1.50, 95% CI 1.23 to 1.81) and patients with liver cirrhosis (SIR=1.95, 95% CI 1.45 to 2.57). Conclusions VTE may be a marker of occult cancer in patients with liver disease. PMID:26462285

    Liver cancer is the 5th most common cancer, but the 2nd leading cause of cancer death, in the world, with more than 700,000 fatalities annually. The major etiology of liver cancer is infection with an hepatotropic virus such as hepatitis B virus (HBV) or hepatitis C virus infection (HCV). While chronic viral infection remains the main cause of liver disease and risk of HCC, rates of non –viral associated HCC are occurring at an alarmingly increasing rate. Like many cancers, survival rates are closely associated with time of detection. If HCC is caught early, survival rates can be as high as 50%. Regrettably, most cases of HCC are caught late where survival rates can be as low as 2–7%. Thus, there has been great interest in discovering serum biomarkers that could be used to identify those with HCC. To this end, many groups have examined the N-linked glycans to identify changes that occur with HCC. As the liver secretes the vast majority of proteins into the serum, this has often been a starting point for study. In serum, alterations in core fucosylation, outer-arm fucosylation, increased sialylation and glycan branching have been observed in patients with HCC. Similar findings have been found directly in HCC tissue suggesting that these glycan changes may play a role in tumor formation and development. PMID:25727150

    Introduction. Colorectal cancer is one of the most frequent cancers in the world and liver metastases are seen in up to 19% of patients with colorectal cancers. Detection of liver metastases is not only vital for sufficient treatment and survival, but also for a better estimation of prognosis. The aim of this study was to evaluate the feasibility of diffusion weighted MRI of the liver as part of a combined MR evaluation of patients with rectal cancers and compare it with the standard preoperative evaluation of the liver with CT. Methods. Consecutive patients diagnosed with rectal cancers were asked to participate in the study. Preoperative CT and diffusion weighted MR (DWMR) were compared to contrast enhanced laparoscopic ultrasound (CELUS). Results. A total of 35 patients were included, 15 patients in Group-1 having the standard CT evaluation of the liver and 20 patients in Group-2 having the standard CT evaluation of the liver and DWMR of the liver. Compared with CELUS, the per-patient sensitivity/specificity was 50/100% for CT, and for DWMR: 100/94% and 100/100% for Reader 1 and 2, respectively. The per-lesion sensitivity of CT and DWMR were 17% and 89%, respectively compared with CELUS. Furthermore, one patient had non-resectable metastases after DWMR despite being diagnosed with resectable metastases after CT. Another patient was diagnosed with multiple liver metastases during CELUS, despite a negative CT-scan. Discussion. DWMR is feasible for preoperative evaluation of liver metastases. The current standard preoperative evaluation with CT-scan results in disadvantages like missed metastases and futile operations. We recommend that patients with rectal cancer, who are scheduled for MR of the rectum, should have a DWMR of the liver performed at the same time. PMID:26793420

    Purpose: To investigate hypoxia measured by pimonidazole binding, glucose transporter 1 (GLUT1) and carbonic anhydrase IX (CA-IX) expression, proliferation, and vascularity in liver metastases of colorectal cancer and to compare GLUT1 and CA-IX expression in corresponding primary tumors. Methods and Materials: Twenty-five patients with liver metastases of colorectal cancer, planned for metastasectomy, were included. The hypoxia marker pimonidazole and proliferation marker iododeoxyuridine were administered before surgery. After immunofluorescent staining of the frozen metastases, pimonidazole binding, vascularity, and proliferation were analyzed quantitatively. Thirteen paraffin-embedded primary tumors were stained immunohistochemically for GLUT1 and CA-IX expression, which was analyzed semiquantitatively in primary tumors and corresponding liver metastases. Results: In liver metastases, pimonidazole binding showed a pattern consistent with diffusion-limited hypoxia. The mean pimonidazole-positive fraction was 0.146; the mean distance from vessels to pimonidazole-positive areas was 80 {mu}m. When expressed, often co-localization was observed between pimonidazole binding and GLUT1 or CA-IX expression, but microregional areas of mismatch were also observed. No correlation between the level of pimonidazole binding and GLUT1 or CA-IX expression was observed. In some patients, a large fraction (up to 30%) of proliferating cells was present in pimonidazole-stained areas. Expression of CA-IX in primary tumors and metastases showed a significant correlation, which was absent for GLUT1 expression. Conclusions: Compared with other tumor types, liver metastases of colorectal cancer contain large amounts of hypoxic cells. The lack of correlation with pimonidazole binding brings into question the value of GLUT1 and CA-IX as endogenous markers of hypoxia.

    The association of hepatitis B virus (HBV) infection and liver cancer is well documented in epidemiological study. Patients with chronic hepatitis B have increased risk of hepatocelluar carcinoma (HCC), in particular those with active liver disease and cirrhosis. The incidence of HCC increases with age and is more common among male patients. The introduction of universal HBV vaccination program for the newborn in endemic regions has started to show beneficial impact. Taiwan introduced this program two decades ago and the incidence of liver cancer among infants and young children have declined significantly. The carcinogenic events leading to HCC are under intense research. A number of hypotheses have been proposed. HBV is not directly hepatotoxic but its interaction with the host immune system creates opportunity for HBV DNA integration into the host genome. One of the main foci of research is the HBX-encoded X protein. Its integration and protein expression impose alteration in cell proliferation cycle and apoptosis process. Many other factors may be involved including viral-induced alterations in p53 and telemerase, HBV genotypes, co-infection with HCV or delta agents, patient's lifestyle such as smoking, alcohol excesses, and genetic factors of the host patient. The processes of necroinflammation, cell proliferation and fibrosis facilitate the initial carcinogenic development. HCC surveillance with tumor markers such as alpha-foetal protein, decarboxylated prothrombin, in conjunction with imaging techniques has identified early small HCC that is amenable to curative therapy. Viral load has been correlated with increase risk of HCC. The available anti-viral agents have demonstrated clinical benefit among those with maintained and sustained response. Interferon and lamivudine therapy have demonstrated reduction of HCC among responders. However, they only constitute a minority proportion of treated patients. The mainstay of prevention should lie in prevention of

    Death, an unavoidable event in the human experience, causes physical as well as mental and spiritual suffering. This paper reports on a nursing experience giving spiritual care to a terminal liver cancer patient between January 17 and February 9, 2009. Eleven nursing logs were used as the source of data for daily information. During the care period, patient religious needs featured prominently, including his desire to become a Christian and his eagerness to know about and help in the arrangement of his funeral. Taking the initiative, the nurse helped link him with religious resources, arranged a minister for his baptism ceremony, had the priest explain funeral proceedings, and assisted with the completion of his entrusted plans. The function of this nursing care intervention was to provide a personal touch to a patient who was in desperate need of warm spiritual care. It is hoped that this report can help caregivers increase their sensitivity toward patient spiritual needs and enhance routine nursing care quality.

    ABSTRACT In this study, we determined the number of peripheral blood circulating tumor cells (CTCs) pre- and post-cryosurgery in patients with colorectal cancer liver metastasis as a reference for understanding the relevance of any changes to the efficacy of cryosurgery. CTC numbers and CTC-related gene expression were measured in the peripheral blood of 55 patients with colorectal liver metastasis at 1 day before and 7 and 30 d after cryoablation using magnetic activated cell sorting (MACS) and fluorescence activated cell sorting (FACS) combined with real-time quantitative PCR (RT-qPCR). The number of CTCs decreased significantly with postoperative time (P < 0.01). Delta cycle threshold values for the CTC-related genes CEA, Ep-CAM, CK18 and CK19 increased significantly after cryoablation. Furthermore, the expression of CEA, Ep-CAM, CK18 and CK19 decreased significantly with time after cryoablation (P < 0.01). RT-qPCR and FACS combined with MACS has significant diagnostic and prognostic value for evaluating the efficacy of cryosurgery in patients with advanced colorectal cancer. PMID:27415969

    Hepatocellular carcinoma (HCC) is the leading cancer death in Taiwan. Chronic viral hepatitis infections have long been considered as the most important risk factors for HCC in Taiwan. The previously published reports were either carried out by individual investigators with small patient numbers or by large endemic studies with limited viral marker data. Through collaboration with 5 medical centers across Taiwan, Taiwan liver cancer network (TLCN) was established in 2005. All participating centers followed a standard protocol to recruit liver cancer patients along with their biosamples and clinical data. In addition, detailed viral marker analysis for hepatitis B virus (HBV) and hepatitis C virus (HCV) were also performed. This study included 3843 HCC patients with available blood samples in TLCN (recruited from November 2005 to April 2011). There were 2153 (56.02%) patients associated with HBV (HBV group); 969 (25.21%) with HCV (HCV group); 310 (8.07%) with both HBV and HCV (HBV+HCV group); and 411 (10.69%) were negative for both HBV and HCV (non-B non-C group). Two hundred two of the 2463 HBV patients (8.20%) were HBsAg(-), but HBV DNA (+). The age, gender, cirrhosis, viral titers, and viral genotypes were all significantly different between the above 4 groups of patients. The median age of the HBV group was the youngest, and the cirrhotic rate was lowest in the non-B non-C group (only 25%). This is the largest detailed viral hepatitis marker study for HCC patients in the English literatures. Our study provided novel data on the interaction of HBV and HCV in the HCC patients and also confirmed that the HCC database of TLCN is highly representative for Taiwan and an important resource for HCC research.

    In patients with liver-limited metastatic colorectal cancer, hepatic resection can offer a significant survival benefit over systemic therapy alone. Specialist hepatobiliary multidisciplinary meetings are currently believed to provide the best forum to discuss the management for these patients. A retrospective analysis was undertaken of patients diagnosed with liver-limited metastatic colorectal cancer over 6 months within a cancer network in the United Kingdom. In addition, patients who were diagnosed but not referred to the hepatobiliary meeting were discussed within a virtual multi-disciplinary setting. Contributors were blinded and proposed management recorded. 159 newly diagnosed patients with liver-limited metastatic colorectal cancer were identified. 68 (43%) were referred at initial diagnosis and 38 (24%) referred following systemic treatment. 35 (51%) who were discussed at baseline underwent a subsequent hepatectomy or radiofrequency ablation, as did 18 (47%) patients referred after chemotherapy. Of the remaining 53 (33%) patients not referred, imaging was available for 31 (58%). Decisions regarding potential liver-directed therapy were discussed within a multi-disciplinary setting. 13 (42%) were identified as resectable or potentially resectable and 11 (36%) may have been suitable for a clinical trial. In reality, none of these 31 patients (100%) underwent surgery or ablation. Whilst the majority of patients with liver-limited metastatic colorectal cancer were referred appropriately, this study demonstrates that a significant number with potentially resectable disease are not being discussed at specialist meetings. A review of all diagnosed cases would ensure that an increased number of patients are offered hepatic resection or ablation. PMID:27174600

    We investigated mechanisms of pancreatic cancer metastasis and defined the biological role of miR-29c in pancreatic cancer metastasis. After two rounds of cell selection in vivo, pancreatic cancer cells with various metastatic potentials derived from spontaneous liver metastases were used as a model of pancreatic cancer to determine the role of miR-29c in pancreatic cancer metastasis. Pancreatic cancer samples were analyzed for miRNA-29c expression, and these levels were associated with survival between groups. miR-29c suppresses cell migration and invasion by targeting the MMP2 3'UTR. Overexpression of miR-29c suppresses pancreatic cancer liver metastasis in a nude mouse orthotopic implantation model. miR-29c expression was associated with metastasis and pancreatic cancer patient survival. miR-29c plays an important role in mediating pancreatic cancer metastasis to the liver by targeting MMP2. Therefore, miR-29c may serve as a novel marker of pancreatic cancer metastasis and possibly as a therapeutic target to treat pancreatic cancer liver metastasis.

    Objective: Cancer represents the second cause of mortality in the world. Saffron as a medicinal plant is known for its anti-cancer and anti-depressant properties. In this randomized double blind clinical trial, the effects of saffron on response to treatment in patients suffering from liver metastasis were evaluated. Materials and Methods: Thirteen patients suffering from liver metastases who referred to Ghaem and Imam Reza hospital, Mashhad, Iran were included in this study and then divided into two different groups. Both groups received chemotherapy regimen. Patients in group one were treated with saffron capsule (50 mg, twice daily) during chemotherapy periods whereas patients in group two received placebo. A sum of the longest diameter were calculated and compared for all lesions in IV contrast CT scan before and after the treatment. Results: from 13 patients included in this study, six patients quit and seven continued until the end. In saffron-treated group, two patients showed partial and complete response (50%) whereas in placebo group, no response was seen. Also, two deaths in placebo and one in saffron group occurred. Conclusion: This research suggests that saffron might be useful in patients suffering from liver metastasis. However, further investigations with larger sample size are required. PMID:26468463

    Both alcohol abuse and liver cirrhosis are known risk factors for various cancers. This article was aimed to assess the long-term risk of malignancies among patients with severe alcoholic liver disease (ALD), i.e., alcoholic liver cirrhosis and alcoholic hepatitis. A cohort of 8,796 male and 3,077 female ALD patients from 1996 to 2012 was identified from the Finnish National Hospital Discharge Register. This nationwide cohort was combined with the data from the Finnish Cancer Registry for incidence of malignancies during the years 1996-2013. The cancer cases diagnosed were compared with the number of cancers in the general population. The number of malignancies in our cohort was 1,052 vs. 368 expected. There was statistically significant excess of cancers of the liver, (standardized incidence ratio [SIR] 59.20; 95% CI 53.11-65.61), pancreas (SIR 3.71; 95% CI 2.72-4.94), pharynx (SIR 9.25; 95% CI 6.05-13.56), mouth (SIR 8.31; 95% CI 4.84-13,29), oesophagus (SIR 7.92; 95% CI 5.49-11.07), tongue (SIR 7,21; 95% CI 3.60-12.89), larynx (SIR 5.20; 95% CI 2.77-8.89), lung (SIR 2.77; 95% CI 2.27-3.32), stomach (SIR 2.76; 95% CI 1.79-4.07), kidney (SIR 2.69; 95% CI 1.84-3.79) and colon (SIR 2.33; 95% CI 1.70-3.11). There was no decreased risk of any cancer among ALD patients. Severe ALD is associated with markedly increased risk of malignancies. The risk is especially high for hepatocellular carcinoma, but also significantly increased for cancers of the upper aerodigestive tract, pancreas and kidneys, and warrants cancer surveillance in selected cases.

    A clear consensus does not exist about whether the initial dose of gemcitabine, an essential anticancer antimetabolite, should be reduced in patients with liver dysfunction. Adult patients with biliary tract or pancreatic cancer were divided into three groups according to whether they had mild, moderate, or severe liver dysfunction, evaluated on the basis of serum bilirubin and liver transaminase levels at baseline. As anticancer treatment, gemcitabine at a dose of 800 or 1000 mg/m(2) was given as an i.v. infusion once weekly for 3 weeks of a 4-week cycle. The patients were prospectively evaluated for adverse events during the first cycle, and the pharmacokinetics of gemcitabine and its inactive metabolite, difluorodeoxyuridine, were studied to determine the optimal initial dose of gemcitabine as monotherapy according to the severity of liver dysfunction. A total of 15 patients were studied. Liver dysfunction was mild in one patient, moderate in six, and severe in eight. All 15 patients had been undergoing biliary drainage for obstructive jaundice when they received gemcitabine. Grade 3 cholangitis developed in one patient with moderate liver dysfunction who received gemcitabine at the dose level of 1000 mg/m(2). No other patients had severe treatment-related adverse events resulting in the omission or discontinuation of gemcitabine treatment. The plasma concentrations of gemcitabine and difluorodeoxyuridine were similar among the groups. An initial dose reduction of gemcitabine as monotherapy for the treatment of biliary tract or pancreatic cancers is not necessary for patients with hyperbilirubinemia, provided that obstructive jaundice is well managed.

    2016-01-01

    Proteoglycans are a group of molecules that contain at least one glycosaminoglycan chain, such as a heparan, dermatan, chondroitin, or keratan sulfate, covalently attached to the protein core. These molecules are categorized based on their structure, localization, and function, and can be found in the extracellular matrix, on the cell surface, and in the cytoplasm. Cell-surface heparan sulfate proteoglycans, such as syndecans, are the primary type present in healthy liver tissue. However, deterioration of the liver results in overproduction of other proteoglycan types. The purpose of this article is to provide a current summary of the most relevant data implicating proteoglycans in the development and progression of human and experimental liver cancer. A review of our work and other studies in the literature indicate that deterioration of liver function is accompanied by an increase in the amount of chondroitin sulfate proteoglycans. The alteration of proteoglycan composition interferes with the physiologic function of the liver on several levels. This article details and discusses the roles of syndecan-1, glypicans, agrin, perlecan, collagen XVIII/endostatin, endocan, serglycin, decorin, biglycan, asporin, fibromodulin, lumican, and versican in liver function. Specifically, glypicans, agrin, and versican play significant roles in the development of liver cancer. Conversely, the presence of decorin could potentially provide protective effects.

    Liver cancer has become the second cause of cancer-related death worldwide. Most patients are still diagnosed at intermediate or advanced stage, where potentially curative treatment options are not recommended. Unlike other solid tumors, there are no validated oncogenic addiction loops and the only systemic agent to improve survival in advanced disease is sorafenib. All phase 3 clinical trials testing molecular therapies after sorafenib have been negative, none of which selected patients based on predictive biomarkers of response. Theoretically, analysis of circulating cancer byproducts (e.g., circulating tumor cells, cell-free nucleic acids), namely "liquid biopsy," could provide easy access to molecular tumor information, improve patients' stratification and allow to assess tumor dynamics over time. Recent technical developments and preliminary data from other malignancies indicate that liquid biopsy might have a role in the future management of cancer patients. PMID:25977189

    In the midst of a worsening obesity epidemic, the incidence of obesity-associated morbidities, including cancer, diabetes, cardiac and liver disease is increasing. Insights into mechanisms underlying pathological obesity-associated inflammation are lacking. Both the omentum, the principal component of visceral fat, and liver of obese individuals are sites of excessive inflammation, but to date the T cell profiles of both compartments have not been assessed or compared in a patient cohort with obesity-associated disease. We have previously identified that omentum is enriched with inflammatory cytokines, chemokines and T cells. Here, we compared the inflammatory profile of T cells in the omentum and liver of patients with the obesity-associated malignancy oesophageal adenocarcinoma (OAC). Furthermore, we assessed the secreted cytokine profile in OAC patient serum, omentum and liver to assess systemic and local inflammation. We observed parallel T cell cytokine profiles and phenotypes in the omentum and liver of OAC patients, in particular CD69(+) and inflammatory effector memory T cells. This study reflects similar processes of inflammation and T cell activation in the omentum and liver, and may suggest common targets to modulate pathological inflammation at these sites.

    AIM: To investigate the efficacy and safety of adjuvant sorafenib after curative resection for patients with Barcelona Clinic Liver Cancer (BCLC)-stage C hepatocellular carcinoma (HCC). METHODS: Thirty-four HCC patients, classified as BCLC-stage C, received adjuvant sorafenib for high-risk of tumor recurrence after curative hepatectomy at a tertiary care university hospital. The study group was compared with a case-matched control group of 68 patients who received curative hepatectomy for HCC during the study period in a 1:2 ratio. RESULTS: The tumor recurrence rate was markedly lower in the sorafenib group (15/34, 44.1%) than in the control group (51/68, 75%, P = 0.002). The median disease-free survival was 12 mo in the study group and 10 mo in the control group. Tumor number more than 3, macrovascular invasion, hilar lymph nodes metastasis, and treatment with sorafenib were significant factors of disease-free survival by univariate analysis. Tumor number more than 3 and treatment with sorafenib were significant risk factors of disease-free survival by multivariate analysis in the Cox proportional hazards model. The disease-free survival and cumulative overall survival in the study group were significantly better than in the control group (P = 0.034 and 0.016, respectively). CONCLUSION: Our study verifies the potential benefit and safety of adjuvant sorafenib for both decreasing HCC recurrence and extending disease-free and overall survival rates for patients with BCLC-stage C HCC after curative resection.

    Patient records from the Guam Cancer Registry were compared with patients listed in a health department viral hepatitis case registry and the numbers of liver cancer and viral hepatitis cases were compared by ethnicity. Hepatitis C was the form of viral hepatitis most common among liver cancer cases on Guam (63.3% of viral hepatitis-associated liver cancer cases). Since viral hepatitis is an important cause of liver cancer, studies such as the present one may provide the information necessary to establish programs (screening of populations at risk and infant vaccination in the case of hepatitis B, for example) that may lessen the impact of liver cancer in the future.

    OBJECTIVE: The authors defined a new macroscopic classification of liver metastases from colorectal cancer. SUMMARY BACKGROUND DATA: There were different prognostic results after the same operative procedure for liver metastases with similar background factors. METHODS: Eighty-one resected liver metastases were classified into simple nodular (SN) or confluent nodular (CN) types according to the characteristics of the cut surface of the tumor. RESULTS: The 5-year survival rates after hepatectomy were 41.7% for the SN lesions (n = 39) and 23.1% for the CN lesions (n = 42). The difference between the survival curves was statistically significant (p = 0.0307). Multivariate analysis using Cox's proportional hazards model revealed that the macroscopic type (p = 0.023), the tumor diameter (p = 0.0001), and the presence of lymph node metastases (p = 0.0016) were statistically significant independent prognostic factors. CONCLUSION: The new macroscopic classification may be valuable as a prognostic factor reflecting the biologic behavior of liver metastases. Images Figure 1. PMID:9389391

    Objectives. We evaluated the value of Gadoxetic acid-enhanced liver MRI in the preoperative staging of colorectal cancer and estimated the clinical impact of liver MRI in the management plan of liver metastasis. Methods. We identified 108 patients who underwent PET/CT and liver MRI as preoperative evaluation of colorectal cancer, between January 2011 and December 2013. We evaluated the per nodule sensitivity of PET/CT and liver MRI for liver metastasis. Management plan changes were estimated for patients with metastatic nodules newly detected on liver MRI, to assess the clinical impact. Results. We enrolled 131 metastatic nodules (mean size 1.6 cm) in 41 patients (mean age 65 years). The per nodule sensitivities of PET/CT and liver MRI were both 100% for nodules measuring 2 cm or larger but were significantly different for nodules measuring less than 2 cm (59.8% and 95.1%, resp., P = 0.0001). At least one more metastatic nodule was detected on MRI in 16 patients. Among these, 7 patients indicated changes of management plan after performing MRI. Conclusions. Gadoxetic acid-enhanced liver MRI detected more metastatic nodules compared with PET/CT, especially for small (<2 cm) nodules. The newly detected nodules induced management plan change in 43.8% (7/16) of patients. PMID:27022613

    Liver is one of the most important organs in energy metabolism. Most plasma apolipoproteins and endogenous lipids and lipoproteins are synthesized in the liver. It depends on the integrity of liver cellular function, which ensures homeostasis of lipid and lipoprotein metabolism. When liver cancer occurs, these processes are impaired and the plasma lipid and lipoprotein patterns may be changed. Liver cancer is the fifth common malignant tumor worldwide, and is closely related to the infections of hepatitis B virus (HBV) and hepatitis C virus (HCV). HBV and HCV infections are quite common in China and other Southeast Asian countries. In addition, liver cancer is often followed by a procession of chronic hepatitis or cirrhosis, so that hepatic function is damaged obviously on these bases, which may significantly influence lipid and lipoprotein metabolism in vivo. In this review we summarize the clinical significance of lipid and lipoprotein metabolism under liver cancer. PMID:17565510

    Purpose: To evaluate quality of life (QoL), an important outcome owing to poor long-term survival, after stereotactic body radiation therapy (SBRT) to the liver. Methods and Materials: Patients (n=222) with hepatocellular carcinoma (HCC), liver metastases, or intrahepatic cholangiocarcinoma and Child-Pugh A liver function received 24-60 Gy of 6-fraction image-guided SBRT. Prospective QoL assessment was completed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core-30 (QLQ-C30) and/or Functional Assessment of Cancer Therapy-Hepatobiliary (FACT-Hep, version 4) questionnaires at baseline and 1, 3, 6, and 12 months after treatment. Ten HCC patients with Child-Pugh B liver function were also treated. Results: The QLQ-C30 was available for 205 patients, and 196 completed the FACT-Hep. No difference in baseline QoL (P=.17) or overall survival (P=.088) was seen between the HCC, liver metastases, and intrahepatic cholangiocarcinoma patients. Appetite loss and fatigue measured by the QLQ-C30 clinically and statistically worsened by 1 month after treatment but recovered by 3 months. At 3 and 12 months after treatment, respectively, the FACT-Hep score had improved relative to baseline in 13%/19%, worsened in 36%/27%, and remained stable in 51%/54%. Using the QLQ-C30 Global Health score, QoL improved in 16%/23%, worsened in 34%/39%, and remained stable in 50%/38% at 3 and 12 months, respectively. Median survival was 17.0 months (95% confidence interval [CI] 12.3-19.8 months). Higher baseline scores on both FACT-Hep and QLQ-C30 Global Health were associated with improved survival. Hazard ratios for death, per 10-unit decrease in QoL, were 0.90 (95% CI 0.83-0.98; P=.001) and 0.88 (95% CI 0.82-0.95; P=.001), respectively. Tumor size was inversely correlated with survival. Conclusions: Liver SBRT temporarily worsens appetite and fatigue, but not overall QoL. Stereotactic body radiation therapy is well tolerated and warrants

    Cardiovascular complications have emerged as a major concern for cancer patients. Many chemotherapy agents are cardiotoxic and some appear to also alter lipid profiles, although the mechanism for this is unknown. We studied plasma lipid levels in 12 breast cancer patients throughout their chemotherapy. Patients received either four cycles of doxorubicin and cyclophosphamide followed by weekly paclitaxel or three cycles of epirubicin, cyclophosphamide and 5'-fluorouracil followed by three cycles of docetaxel. Patients demonstrated a significant reduction (0.32 mmol/L) in high density lipoprotein cholesterol (HDL-C) and apolipoprotein A1 (apoA1) levels (0.18 g/L) and an elevation in apolipoprotein B (apoB) levels (0.15 g/L) after treatment. Investigation of the individual chemotherapy agents for their effect on genes involved in lipoprotein metabolism in liver cells showed that doxorubicin decreased ATP binding cassette transporter A1 (ABCA1) via a downregulation of the peroxisomal proliferator activated receptor γ (PPARγ) and liver X receptor α (LXRα) transcription factors. In contrast, ABCA1 levels were not affected by cyclophosphamide or paclitaxel. Likewise, apoA1 levels were reduced by doxorubicin and remained unaffected by cyclophosphamide and paclitaxel. Doxorubicin and paclitaxel both increased apoB protein levels and paclitaxel also decreased low density lipoprotein receptor (LDLR) protein levels. These findings correlate with the observed reduction in HDL-C and apoA1 and increase in apoB levels seen in these patients. The unfavourable lipid profiles produced by some chemotherapy agents may be detrimental in the longer term to cancer patients, especially those already at risk of cardiovascular disease (CVD). This knowledge may be useful in tailoring effective follow-up care plans for cancer survivors.

    Liver cancer is an aggressive malignant disease with a poor prognosis. Patients with liver cancer are usually diagnosed at an advanced stage and thus miss the opportunity for surgical resection. Chemotherapy and radiofrequency ablation, which target tumor bulk, have exhibited limited therapeutic efficacy to date. Liver cancer stem cells (CSCs) are a small subset of undifferentiated cells existed in liver cancer, which are considered to be responsible for liver cancer initiation, metastasis, relapse and chemoresistance. Elucidating liver CSC characteristics and disclosing their regulatory mechanism might not only deepen our understanding of the pathogenesis of liver cancer but also facilitate the development of diagnostic, prognostic and therapeutic approaches to improve the clinical management of liver cancer. In this review, we will summarize the recent advances in liver CSC research in terms of the origin, identification, regulation and clinical correlation.

    Purpose We developed a new method of detecting circulating tumor cells (CTCs) in liver cancer patients by constructing cell blocks from peripheral blood cells, including CTCs, followed by multiple immunohistochemical analysis. Materials and Methods Cell blockswere constructed from the nucleated cell pellets of peripheral blood afterremoval of red blood cells. The blood cell blocks were obtained from 29 patients with liver cancer, and from healthy donor blood spikedwith seven cell lines. The cell blocks and corresponding tumor tissues were immunostained with antibodies to seven markers: cytokeratin (CK), epithelial cell adhesion molecule (EpCAM), epithelial membrane antigen (EMA), CK18, α-fetoprotein (AFP), Glypican 3, and HepPar1. Results The average recovery rate of spiked SW620 cells from blood cell blocks was 91%. CTCs were detected in 14 out of 29 patients (48.3%); 11/23 hepatocellular carcinomas (HCC), 1/2 cholangiocarcinomas (CC), 1/1 combined HCC-CC, and 1/3 metastatic cancers. CTCs from 14 patients were positive for EpCAM (57.1%), EMA (42.9%), AFP (21.4%), CK18 (14.3%), Gypican3 and CK (7.1%, each), and HepPar1 (0%). Patients with HCC expressed EpCAM, EMA, CK18, and AFP in tissue and/or CTCs, whereas CK, HepPar1, and Glypican3 were expressed only in tissue. Only EMA was significantly associated with the expressions in CTC and tissue. CTC detection was associated with higher T stage and portal vein invasion in HCC patients. Conclusion This cell block method allows cytologic detection and multiple immunohistochemical analysis of CTCs. Our results show that tissue biomarkers of HCC may not be useful for the detection of CTC. EpCAM could be a candidate marker for CTCs in patients with HCC. PMID:27034142

    c-MET is implicated in the pathogenesis and growth of a wide variety of human malignancies, including colorectal cancer (CRC). The aim of the present study was to clarify the association between c-MET expression and tumor recurrence in CRC patients after curative liver resection, and to evaluate concordance in c-MET expression and various mutations of KRAS, BRAF and PIK3CA between primary CRC and paired liver metastases. A cohort of patients was tested for c-MET immunoreactivity (i.e. immunohistochemistry [IHC]) and KRAS, BRAF and PIK3CA mutations. Analyses were performed both on primary tumors and paired liver metastases, and the association between IHC and mutations results were assessed. A total of 108 patients were eligible. A total of 53% of patients underwent simultaneous resection of primary tumors and metastases, and the others underwent metachronous resection. Levels of concordance between primary tumors and metastases were 65.7%, 87.7%, 100% and 95.2% for c-MET, KRAS, BRAF and PIK3CA, respectively. High levels of c-MET expression (c-MET-high) in the primary tumors were observed in 52% of patients. Relapse-free survival was significantly shorter for patients with c-MET-high primary tumors (9.7 months) than for those with c-MET-low primary tumors (21.1 months) (P = 0.013). These results suggest that a high level of genetic concordance in KRAS, BRAF and PIK3CA between primary tumors and liver metastases, and c-MET-high in the primary tumors were associated with shorter relapse-free survival after hepatic metastasectomy.

    Purpose. We retrospectively evaluated the safety and efficacy of preoperative initial hepatic arterial infusion chemotherapy (HAIC) through a port-catheter system in patients with liver dysfunction due to synchronous and unresectable liver metastases. The aim of HAIC was to improve patients' clinical condition for later surgical removal of primary colorectal cancer. Methods. Port-catheter systems were placed radiologically in 21 patients (mean age 58.6 {+-} 8.1 years) with liver dysfunction due to synchronous liver metastases from colorectal cancer. Initial HAIC of 1,000 mg/m{sup 2} 5-fluorouracil was administered weekly as a 5 hr continuous infusion through this system. Surgical removal of the primary lesion was planned after HAIC improved the liver function. Results. Port-catheter system placement was successful in all patients without severe complications. Patients were followed up for a median of 309 days (range 51-998 days). After starting HAIC, no severe adverse events that caused drug loss and treatment postponement or suspension were observed in any of the patients. HAIC was performed a mean of 4.5 {+-} 3.0 times and the liver function improved in all patients. Curative (n = 18) or palliative (n = 1) surgical removal of the primary lesion was performed. The remaining 2 patients died because extrahepatic metastases developed and their performance status worsened; thus, surgery could not be performed. The median survival times of all patients and the operated patients were 309 and 386 days, respectively. Conclusion. Initial HAIC administration is a safe and efficacious method for improving liver function prior to operative resection of primary colorectal cancer in patients with liver dysfunction due to synchronous and unresectable liver metastases.

    PurposeThis prospective study evaluated the effectiveness and safety of TACE using irinotecan loaded superabsorbent polymer (SAP) microspheres for treatment of colorectal cancer liver metastases (CCLM) in a salvage setting of patients.MethodsA total of 71 TACE procedures were performed in 29 patients with liver only or liver-dominant CCLM. In all patients, systemic chemotherapy before TACE had failed. Two hundred milligrams of irinotecan were loaded into 50–100 mg of SAP microspheres (HepaSphere™ Microspheres) considering tumor size and vascularization. TACE was performed selectively with respect to tumor distribution. Response was evaluated following RECIST and EASL criteria, respectively. Median follow-up after last TACE was 8 (range 1–54) months. All patients had died at time of analysis.ResultsAll TACE procedures were performed successfully; 35–400 mg (mean 168.3 mg) of irinotecan loaded in 13–100 mg (mean 48.3 mg) SAP microspheres were injected during individual sessions. No major complications occurred. Three, 6, and 12 months after first TACE complete and partial response was present in 72, 32 %, 0 of patients by EASL criteria and stable disease was seen in 86, 48, and 8 % with no complete and no partial response by RECIST criteria. Median overall survival after first TACE was 8 months, and median time to progression was 5 months. Median overall survival was longer in patients with limited (<25 %) compared with extensive (>50 %) intrahepatic disease (21 vs. 5 months, p < 0.005).ConclusionsTACE using irinotecan loaded SAP microspheres is safe and effective in terms of tumor necrosis. Survival benefit in a salvage setting seems to be limited in patients with advanced intrahepatic tumor load.

    Obesity has become a universal and major public health problem with increasing prevalence in both adults and children in the 21st century, even in developing countries. Extensive epidemiological studies reveal a strong link between obesity and development and progression of various types of cancers. The connection between obesity and liver cancer is particularly strong and obesity often results in liver diseases such as non-alcoholic fatty liver disease (NAFLD) and the more severe non-alcoholic steatohepatitis (NASH). NASH is characterized by fatty liver inflammation and is believed to cause fibrosis and cirrhosis. The latter is a known liver cancer risk factor. In fact due to its much higher prevalence obesity may be a more substantial contributor to overall hepatocellular carcinoma burden than infection with hepatitis viruses. Here we review and discuss recent advances in elucidation of cellular and molecular alterations and signaling pathways associated with obesity and liver inflammation and their contribution to hepatocarcinogenesis.

    Liver cancer is an extraordinarily heterogeneous malignant disease among the tumors that have so far been identified. Hepatocellular carcinoma (HCC) arises most frequently in the setting of chronic liver inflammation and fibrosis, and takes a variety of course in individual patients to process to tumor. The risk factors such as HBV and/or HCV infections, aflatoxin infection, abuse alcohol intake, metabolic syndrome, obesity and diabetes are closely related to the environmental and genetic susceptibilities to HCC. The consequent resulting genomic instability, molecular and signal transduction network disorders and microenvironmental discrepancies are characterized by the extraordinary heterogeneity of liver cancer. The histology-based definition of the morphological heterogeneity of liver cancer has been modified and refined to treat patients with targeted therapies, but this still cannot solve all the problems. Lack of consistent outcome for anticancer agents and conventional therapies in liver cancer treatment calls for assessing the benefits of new molecularly targeted drugs and combined therapy, under the heterogeneity condition of tumor. The present review article will provide the complex mechanism and phenotype of liver cancer heterogeneity, and help us to execute precision medicine in a really personalized manner.

    Liver cancer (hepatocellular carcinoma or HCC) is a major cancer worldwide. Research in this field is needed to identify biomarkers that can be used for early detection of the disease as well as new approaches to its treatment. Epigenetic biomarkers provide an opportunity to understand liver cancer etiology and evaluate novel epigenetic inhibitors for treatment. Traditionally, liver cirrhosis, proteomic biomarkers, and the presence of hepatitis viruses have been used for the detection and diagnosis of liver cancer. Promising results from microRNA (miRNA) profiling and hypermethylation of selected genes have raised hopes of identifying new biomarkers. Some of these epigenetic biomarkers may be useful in risk assessment and for screening populations to identify who is likely to develop cancer. Challenges and opportunities in the field are discussed in this chapter.

    Eight patients with locally extensive colorectal cancer were treated with colloidal P-32 chromic phosphate via the superiod mesenteric artery following resection to prevent development of liver metastases. Less than 2% of the injected dose was found in the right atrial blood following the first pass through the liver and less than 1% in the urine. Therapy was tolerated well by all patients, with no acute complications. Long-term follow-up is needed to determine the effect of P-32 on the liver and the frequency of hepatic metastases.

    Aim To evaluate the outcomes among elderly (≥70 years) and younger patients (<70 years) with liver-dominant metastatic colorectal cancer (mCRC) who received radioembolization (RE) as salvage therapy. Methods A retrospective review of 107 consecutive patients with unresectable mCRC treated with RE after failing first- and second-line chemotherapy. Results From 2002 to 2012, 44 elderly and 63 younger (<70 years) patients received RE. Patients had similar previous extensive chemotherapy and liver-directed interventions. Using modified Response Evaluation Criteria in Solid Tumors (mRECIST) criteria, either a stable or a partial radiographical response was seen in 65.8% of the younger compared with 76.5% of the elderly patients. RE was equally well tolerated in both groups and common procedure-related adverse events were predominantly grade 1–2 and of short duration. No significant difference was found with regard to overall median survival between younger [8.4 months; 95% confidence interval (CI) = 6.2–10.6] or elderly patients (8.2 months; 95% CI = 5.9–10.5, P = 0.667). The presence of extrahepatic disease at the time of RE was associated with a significantly worse median survival in both groups. Conclusion Radioembolization appears to be as well tolerated and effective for the elderly as it is for younger patients with mCRC. Age alone should not be a discriminating factor for the use of radioembolization in the management of mCRC patients. PMID:25123597

    Background: The present study was aimed to evaluate the efficacy and safety of at least three cycles of Bevacizumab in combination with chemotherapy regimens, FOLFIRI or FOLFOX to treat liver metastatic colorectal cancer and improved response rates in these patients. Materials and Methods: In this non-randomized clinical trial, 38 patients were enrolled and followed for 12-weeks period of chemotherapy. Fifteen patients under treated with FOLOFX (Group I), 15 patients under treated with FOLOFIRI (Group II), 4 patients under treated with FOLOFX + Bevacizumab (Group III), and 34 patients under treated with FOLOFIRI + Bevacizumab (Group IV). Response to treatment was assessed in all patients as main endpoint. Patients in groups I and II, who did not response to treatment after 12 weeks of chemotherapy, were followed by groups III and IV regimens, respectively, for 12 weeks. Results: Overall response rate was 35% (19 of 54), and complete response (CR), partial response (PR), progressive disease (PD), and stable disease (SD) rates in all patients were 18%, 17%, 35%, and 30%. PR, SD, and PD were different among groups, but no statistical significance was noted among groups (P-value >0.05). No patient achieved a CR in groups III and IV, although CR was observed in 4 patients (27%) and 6 patients (40%) in groups I and II, respectively. The rare of CR was statistically significant among studied groups (P-value = 0.013). Conclusion: Results showed that adding Bevacizumab to chemotherapy regimens, in patients who did not response to FOLFIRI or FOLFOX regimen, did not increase CR in these patients. PMID:26962512

    Grasso, P

    There is no clear indication that malnutrition, per se, is a principal cause of cancer in man, but the prevalence of liver cancer in areas where malnutrition exists supports this hypothesis. Liver damage and liver cancer have been induced in laboratory rats by diets consisting of peanut meal and proteins deficient in some essential amino acids. However, liver damage, but not cancer, was produced when the diets contained no peanut meal but consisted of a mixture of amino acids deficient in methionine and cysteine, so that it is possible that aflatoxin, a contaminant of peanut meal, may have been responsible for the malignancies seen in the earlier experiments. Liver cancer developes in a high proportion of mice allowed to feed ad libitum or given a diet containing a high proportion of fat (groundnut oil) or protein (casein). Dietary restriction reduced the incidences of this cancer. This findings lends some support to current thinking that diet may be a factor in the development of cancer in man.

    Belinostat is a hydroxamate class HDAC inhibitor that has demonstrated activity in peripheral T-cell lymphoma and is undergoing clinical trials for non-hematologic malignancies. We studied the pharmacokinetics of belinostat in hepatocellular carcinoma patients to determine the main pathway of metabolism of belinostat. The pharmacokinetics of belinostat in liver cancer patients were characterized by rapid plasma clearance of belinostat with extensive metabolism with more than 4-fold greater relative systemic exposure of major metabolite, belinostat glucuronide than that of belinostat. There was significant interindividual variability of belinostat glucuronidation. The major pathway of metabolism involves UGT1A1-mediated glucuronidation and a good correlation has been identified between belinostat glucuronide formation and glucuronidation of known UGT1A1 substrates. In addition, liver microsomes harboring UGT1A1*28 alleles have lower glucuronidation activity for belinostat compared to those with wildtype UGT1A1. The main metabolic pathway of belinostat is through glucuronidation mediated primarily by UGT1A1, a highly polymorphic enzyme. The clinical significance of this finding remains to be determined.

    Background Prognosis of patients with colorectal cancer liver metastasis (CRCLM) is estimated based on clinicopathological models. Stratifying patients based on tumor biology may have additional value. Methods Tissue micro-arrays (TMAs), containing resected CRCLM and corresponding primary tumors from a multi-institutional cohort of 507 patients, were immunohistochemically stained for 18 candidate biomarkers. Cross-validated hazard rate ratios (HRRs) for overall survival (OS) and the proportion of HRRs with opposite effect (P(HRR < 1) or P(HRR > 1)) were calculated. A classifier was constructed by classification and regression tree (CART) analysis and its prognostic value determined by permutation analysis. Correlations between protein expression in primary tumor-CRCLM pairs were calculated. Results Based on their putative prognostic value, EGFR (P(HRR < 1) = .02), AURKA (P(HRR < 1) = .02), VEGFA (P(HRR < 1) = .02), PTGS2 (P(HRR < 1) = .01), SLC2A1 (P(HRR > 1) < 01), HIF1α (P(HRR > 1) = .06), KCNQ1 (P(HRR > 1) = .09), CEA (P (HRR > 1) = .05) and MMP9 (P(HRR < 1) = .07) were included in the CART analysis (n = 201). The resulting classifier was based on AURKA, PTGS2 and MMP9 expression and was associated with OS (HRR 2.79, p < .001), also after multivariate analysis (HRR 3.57, p < .001). The prognostic value of the biomarker-based classifier was superior to the clinicopathological model (p = .001). Prognostic value was highest for colon cancer patients (HRR 5.71, p < .001) and patients not treated with systemic therapy (HRR 3.48, p < .01). Classification based on protein expression in primary tumors could be based on AURKA expression only (HRR 2.59, p = .04). Conclusion A classifier was generated for patients with CRCLM with improved prognostic value compared to the standard clinicopathological prognostic parameters, which may aid selection of patients who may benefit from adjuvant systemic therapy.

    Purpose: In clinical trials with yttrium-90-resin-microspheres for the management of colorectal cancer liver metastases, it was observed that radioembolization might result in splenomegaly and an increase in portal vein size. Subclinical hepatitis in normal liver tissue as well as the effects of radioembolization and prior chemotherapy are suspected to be responsible for this phenomenon. The purpose of this study was to quantify the changes in liver and spleen volume and portal vein diameter after radioembolization. Methods: Twenty-seven patients with liver-dominant metastatic disease from breast cancer who had not responded to chemotherapy or had to abandon chemotherapy because of its toxic effects were evaluated. Changes in liver and spleen volume and portal vein diameter as well as liver tumor volume and diameter were quantified using computed tomography scans. Results: Radioembolization was associated with a significant mean decrease in the whole liver volume of 10.2% (median 16.7%; P = 0.0024), mainly caused by a reduction in the right lobe volume (mean 16.0%; P < 0.0001). These changes were accompanied by a significant increase in the diameter of the main portal vein (mean 6.8%; P < 0.0001) as well as splenic volume (mean 50.4%; P < 0.0001). Liver-tumor volume and diameter decreased by a median of 24 and 39.7%. Conclusions: Radioembolization is an effective treatment for tumor size reduction in patients with breast cancer liver metastases. Treatment is associated with changes of hepatic parenchymal volume, splenic volume, and portal vein size that appear not to represent clinically important sequelae in this patient cohort.

    Hepatocellular carcinoma (HCC), the most common form of primary liver cancer is the third leading cause of cancer-related cell death in human and the fifth in women worldwide. The incidence of HCC is increasing despite progress in identifying risk factors, understanding disease etiology and developing anti-viral strategies. Therapeutic options are limited and survival after diagnosis is poor. Therefore, better preventive, diagnostic and therapeutic tools are urgently needed, in particular given the increased contribution from systemic metabolic disease to HCC incidence worldwide. In the last three decades, technological advances have facilitated the generation of genetically engineered mouse models (GEMMs) to mimic the alterations frequently observed in human cancers or to conduct intervention studies and assess the relevance of candidate gene networks in tumor establishment, progression and maintenance. Because these studies allow molecular and cellular manipulations impossible to perform in patients, GEMMs have improved our understanding of this complex disease and represent a source of great potential for mechanism-based therapy development. In this review, we provide an overview of the current state of HCC modeling in the mouse, highlighting successes, current challenges and future opportunities.

    Hepatocellular carcinoma (HCC) is the second most common cause of cancer mortality worldwide. Most cases of HCC are associated with cirrhosis related to chronic hepatitis B virus or hepatitis C virus infections. Hypermethylation of promoter regions is the main epigenetic mechanism of gene silencing and has been involved in HCC development. The aim of this study was to determine whether aberrant methylation of RASSF1A and DOK1 gene promoters is associated with the progression of liver disease in Brazilian patients. Methylation levels were measured by pyrosequencing in 41 (20 HCC, 9 cirrhotic, and 12 non-cirrhotic) liver tissue samples. Mean rates of methylation in RASSF1A and DOK1 were 16.2% and 12.0% in non-cirrhotic, 26.1% and 19.6% in cirrhotic, and 59.1% and 56.0% in HCC tissues, respectively, showing a gradual increase according to the progression of the disease, with significantly higher levels in tumor tissues. In addition, hypermethylation of RASSF1A and DOK1 was found in the vast majority (88%) of the HCC cases. Interestingly, DOK1 methylation levels in HCC samples were significantly higher in the group of younger (<40 years) patients, and higher in moderately differentiated than in poorly differentiated tumors (p < 0.05). Our results reinforce the hypothesis that hypermethylation of RASSF1A and DOK1 contributes to hepatocarcinogenesis and is associated to clinicopathological characteristics. RASSF1A and DOK1 promoter hypermethylation may be a valuable biomarker for early diagnosis of HCC and a potential molecular target for epigenetic-based therapy. PMID:27078152

    We recently observed inhibition of weight loss in patients with advanced nonsmall-cell lung cancer after intravenous infusion of ATP. Because liver ATP levels were found to be decreased in lung cancer patients with weight loss, the present 31P magnetic resonance spectroscopy (MRS) study was aimed at investigating whether ATP infusion restores liver energy status in these patients. Nine patients with advanced nonsmall-cell lung cancer (stage IIIB/IV) were studied 1 week before (baseline) and at 22 to 24 hours of continuous ATP infusion (37-75 microg/kg/min). Localized hepatic 31P MR spectra (repetition time 15 seconds), obtained in the overnight-fasted state, were analyzed for ATP and P(i) content. Ten healthy subjects (without ATP infusion) served as control. Liver ATP levels in lung cancer patients increased from 8.8 +/- 0.7% (relative to total MR-detectable phosphate; mean +/- SE) at baseline to 12.2 +/- 0.9% during ATP infusion (P <.05), i.e., a level similar to that in healthy subjects (11.9 +/- 0.9%). The increase in ATP level during ATP infusion was most prominent in patients with > or = 5% weight loss (baseline: 7.9 +/- 0.7%, during ATP infusion: 12.8 +/- 1.0%, P < 0.01). In conclusion, ATP infusion restores hepatic energy levels in patients with advanced lung cancer, especially in weight-losing patients. These changes may contribute to the previously reported beneficial effects of ATP infusion on the nutritional status of lung cancer patients. PMID:11826418

    The purpose of this study was to assess retrospectively the sequential treatment of hepatic arterial infusion (HAI) chemotherapy followed by systemic therapy using oxaliplatin plus 5-flourouracil (5-FU) and leucovorin, namely, FOLFOX, for patients with liver metastases from colorectal cancer. We reviewed 20 patients with unresectable liver metastases from colorectal cancer. Patients were initially treated with HAI chemotherapy until disease progression (5-fluorouracil, 1000 mg/m{sup 2} intra-arterial infusion, weekly) and then with FOLFOX thereafter (FOLFOX4, n = 13; modified FOLFOX6, n = 7). Adverse events, tumor response, and time to progression for each therapy were evaluated retrospectively, and overall survival was estimated. Toxicity of HAI chemotherapy was generally mild. Of 20 patients, adverse events leading to treatment discontinuation occurred in only 1 patient (5%) during initial therapy using HAI chemotherapy, while 9 patients (45%) exhibited adverse events during subsequent FOLFOX therapy. For HAI chemotherapy and FOLFOX, objective response rates were 85.0% and 35.0%, respectively, and median time to progression was 11.6 and 5.1 months, respectively. Median overall survival was 30.1 months. In conclusion, the sequence of HAI chemotherapy followed by FOLFOX is a promising treatment strategy for the long-term use of active chemotherapeutic agents, leading to a superior tumor response and fewer toxic effects in patients with unresectable liver metastases from colorectal cancer.

    Cancer stem cells (CSCs) are a small subpopulation in cancer, have been proposed to be cancer-initiating cells, and have been shown to be responsible for chemotherapy resistance and cancer recurrence. The identification of CSC subpopulations inside a tumor presents a new understanding of cancer development because it implies that tumors can only be eradicated by targeting CSCs. Although advances in liver cancer detection and treatment have increased the possibility of curing the disease at early stages, unfortunately, most patients will relapse and succumb to their disease. Strategies aimed at efficiently targeting liver CSCs are becoming important for monitoring the progress of liver cancer therapy and for evaluating new therapeutic approaches. Herein, we provide a critical discussion of biological markers described in the literature regarding liver cancer stem cells and the potential of these markers to serve as therapeutic targets.

    This study examined the impact of the operative and peri-operative factors on the long-term prognosis of patients with primary liver cancer undergoing hepatectomy. A total of 222 patients with primary liver cancer who underwent hepatectomy were followed up from January 1986 to December 2010 at Chinese PLA General Hospital. The post-operative complication rate was 14.0% for all cases, 13.7% for hepatocellular carcinoma (HCC), 10.0% for cholangiocarcinoma. The 1-, 3-, 5- and 10-year overall survival rates in patients with primary liver cancer after resection were 76.6%, 57.6%, 41.4%, and 21.0%. The survival rates were significantly higher in the HCC group than in the cholangiocarcinoma group (P=0.000), in the non-anatomical resection group than in the anatomical resection group (P=0.005), in the female group than in the male group (P=0.002), in patients receiving no blood transfusion than in those who were given intra-operative blood transfusion (P=0.000), in patients whose intra-operative blood loss was less than 400 mL than in those who intra-operatively lost more than 400 mL (P=0.000). No significant difference was found in the survival rate between the HBsAg-positive group and the HBsAg-negative group (P=0.532). Our study showed that anatomical resection, blood loss and blood transfusion were predictors of poor survival after hepatectomy for primary liver cancer patients, and concomitant hepatitis B virus infection bore no relation with the post-resection survival.

    BACKGROUND Liver metastases are associated with a poor prognosis. We investigated the use of hepatic arterial infusion (HAI) of irinotecan combination therapy in patients with liver metastases. PATIENTS AND METHODS Patients with histologically confirmed advanced cancer with liver metastases that was refractory to standard therapy were eligible. A standard “3+3” phase I study design was used to determine the dose-limiting toxicity (DLT) and the maximum tolerated dose (MTD). Three cohorts were evaluated: HAI of irinotecan with systemic intravenous (IV) (a) bevacizumab, (b) oxaliplatin and bevacizumab, or (c) bevacizumab and cetuximab. RESULTS From October 2009 through December 2013, 98 patients with various tumor types were enrolled (median age, 62 years, range, 34–85; and median number of prior therapies, 4, range, 1–11). In cohorts A and C, dose escalation continued until the highest dose level—considered the MTD—was reached. In cohort B, dose escalation continued until dose level 3, and dose level 2 was considered the MTD. Rates of grade 3/4 adverse events were as follows: diarrhea, 8%; fatigue, 4%; neutropenia, 4%; thrombocytopenia, 2%; and skin rash, 2%. Seventy-seven patients were evaluable for response. Partial response was noted in 5 (6.5%) patients (neuroendocrine cancer, n=2; CRC, n=2; NSCLC, n=1); and stable disease ≥ 6 months in 17 (22.1%) patients (CRC, n=13; breast, n=1; neuroendocrine, n=1; NSCLC, n=1; pancreatic, n=1). CONCLUSIONS HAI irinotecan in combination with bevacizumab; oxaliplatin plus bevacizumab; or cetuximab plus bevacizumab was safe and may be a treatment option for selected patients with advanced cancer and liver involvement.

    Liver Cancer has been a leading cause of death in Thailand. The purpose of this study was to model and forecast liver cancer mortality rate in Thailand using death certificate reports. A retrospective analysis of the liver cancer mortality rate was conducted. Numbering of 123,280 liver cancer causes of death cases were obtained from the national vital registration database for the 10-year period from 2000 to 2009, provided by the Ministry of Interior and coded as cause-of-death using ICD-10 by the Ministry of Public Health. Multivariate regression model was used for modeling and forecasting age-specific liver cancer mortality rates in Thailand. Liver cancer mortality increased with increasing age for each sex and was also higher in the North East provinces. The trends of liver cancer mortality remained stable in most age groups with increases during ten-year period (2000 to 2009) in the Northern and Southern. Liver cancer mortality was higher in males and increase with increasing age. There is need of liver cancer control measures to remain on a sustained and long-term basis for the high liver cancer burden rate of Thailand.

    A 58-year-old woman was diagnosed with a sigmoid colon cancer and synchronous liver metastasis. Because an obstruction of the sigmoid colon was identified, the patient underwent sigmoidectomy. Computed tomography(CT)findings suggested possible vena cava and hepatic vein invasion. Therefore, the decision was made to offer systemic chemotherapy. The patient underwent 6 courses of chemotherapy with 5-fluorouracil, Leucovorin, and oxaliplatin (mFOLFOX6). After 4 courses of chemotherapy, CT scans showed a significant reduction of the liver metastasis (reduction rate of 5 0%; a partial response) and demonstrated improved exclusion of the inferior vena cava and hepatic vein. After 6 courses of chemotherapy, we performed right trisegmentectomy of the liver and resection of the inferior vena cava and diaphragm. Postoperative pathological findings revealed negative margins, and no invasion of the inferior vena cava. The pathological response grade of the tumor after chemotherapy was determined to be Grade 2. Adjuvant chemotherapy was not performed because of the patient 's poor performance status. The patient was alive with no recurrence 8 years after resection of the liver metastasis. PMID:26805305

    BACKGROUND Cerebral hemorrhage is common in patients with cancer, but the clinical features and pathogenesis of liver cancer patients with cerebral hemorrhage are not well known. MATERIAL AND METHODS Liver cancer patients who developed cerebral hemorrhage were recruited from the First Affiliated Hospital of Guangxi Medical University between January 2003 and December 2014. We retrospectively analyzed clinical presentations, results of laboratory tests, and imaging examinations. The clinical features and pathogenesis were summarized. RESULTS Among 11133 patients with liver cancer, 9 patients (0.08%), including 3 females and 6 males met the inclusion criteria. The age range was 48-73 years and the average age was 61.67±8.97 years. Five patients did not have traditional hemorrhage risk factors and 4s had the risk factors; however, all had developed hepatocellular carcinoma, and 3 had developed metastasis. All 9 patients showed elevated tumor markers: an increased AFP level was detected in 6 patients, coagulation dysfunctions in 8 patients, and abnormal liver functions in 6 patients. Five patients had developed cerebral hemorrhagic lesions in the lobes of their brains, while hemorrhagic lesions in the basal ganglia occurred in 3 patients and in the brainstem in only 1 patient. Four patients had clear consciousness, while 5 patients were in coma and showed poor prognosis. CONCLUSIONS Patients who have liver cancer complicated with cerebral hemorrhage usually lack traditional risk factors of cerebral hemorrhage. The site of cerebral hemorrhage is often detected in the lobes of the brain. Coagulation dysfunctions might be the main pathogenesis of liver cancer complicated with cerebral hemorrhage.

    BACKGROUND In the current American Joint Committee on Cancer/International Union Against Cancer staging system (seventh edition) for intrahepatic cholangiocarcinoma (ICC), tumor size was excluded, and periductal invasion was added as a new tumor classification‐defining factor. The objective of the current report was to propose a new staging system for ICC that would be better for stratifying the survival of patients based on data from the nationwide Liver Cancer Study Group of Japan database. METHODS Of 756 patients who underwent surgical resection for ICC between 2000 and 2005, multivariate analyses of the clinicopathologic factors of 419 patients who had complete data sets were performed to elucidate relevant factors for inclusion in a new tumor classification and staging system. RESULTS Overall survival data were best stratified using a cutoff value of 2 cm using a minimal P value approach to discriminate patient survival. The 5‐year survival rate of 15 patients who had ICC measuring ≤2 cm in greatest dimension without lymph node metastasis or vascular invasion was 100%, and this cohort was defined as T1. Multivariate analysis of prognostic factors for 267 patients with lymph node‐negative and metastasis‐negative (N0M0) disease indicated that the number of tumors, the presence arterial invasion, and the presence major biliary invasion were independent and significant prognostic factors. The proposed new system, which included tumor number, tumor size, arterial invasion, and major biliary invasion for tumor classification, provided good stratification of overall patient survival according to disease stage. Macroscopic periductal invasion was associated with major biliary invasion and an inferior prognosis. CONCLUSIONS The proposed new staging system, which includes a tumor cutoff size of 2 cm and major biliary invasion, may be useful for assigning patients to surgery.

    Chromosomal instability is a well-defined hallmark of tumor aggressiveness and metastatic progression in colorectal cancer. The magnitude of genetic heterogeneity among distinct liver metastases from the same patient at the copy number level, as well as its relationship with chemotherapy exposure and patient outcome, remains unknown. We performed high-resolution DNA copy number analyses of 134 liver metastatic deposits from 45 colorectal cancer patients to assess: (i) intra-patient inter-metastatic genetic heterogeneity using a heterogeneity score based on pair-wise genetic distances among tumor deposits; and (ii) genomic complexity, defined as the proportion of the genome harboring aberrant DNA copy numbers. Results were analyzed in relation to the patients’ clinical course; previous chemotherapy exposure and outcome after surgical resection of liver metastases. We observed substantial variation in the level of intra-patient inter-metastatic heterogeneity. Heterogeneity was not associated with the number of metastatic lesions or their genomic complexity. In metachronous disease, heterogeneity was higher in patients previously exposed to chemotherapy. Importantly, intra-patient inter-metastatic heterogeneity was a strong prognostic determinant, stronger than known clinicopathological prognostic parameters. Patients with a low level of heterogeneity (below the median level) had a three-year progression-free and overall survival rate of 23% and 66% respectively, versus 5% and 18% for patients with a high level (hazard ratio0.4, 95% confidence interval 0.2–0.8, P = 0.01; and hazard ratio0.3,95% confidence interval 0.1–0.7, P = 0.007). A low patient-wise level of genomic complexity (below 25%) was also a favorable prognostic factor; however, the prognostic association of intra-patient heterogeneity was independent of genomic complexity in multivariable analyses. In conclusion, intra-patient inter-metastatic genetic heterogeneity is a pronounced feature of

    Attributes of age, tobacco use, and alcohol consumption were studied in order to elucidate their roles in the increased risks of blacks for selected neoplasms. Black cancer patients with and without liver cirrhosis were compared by cancer sites, age, tobacco usage, and alcohol consumption. Subsequently, non-cirrhotic blacks and whites with cancer were characterized on the same variables.Black males with cancer and liver cirrhosis, when compared with similar males without liver cirrhosis, were significantly younger and had more than triple the frequencies of esophageal and hepatic cancers but less than one fourth the frequencies of gastric and prostatic cancers. Cirrhotic patients were rarely nondrinkers but drank whiskey excessively. Noncirrhotic blacks, when compared with noncirrhotic whites, had very high risks of liver, stomach, and prostate cancers and smoked less heavily but drank significantly more whiskey. Hence, factors associated with patterns of smoking cigarettes and drinking, especially whiskey, if not these habits themselves, are probably related to the increased risks of blacks for stomach and liver cancers when compared with non-cirrhotic whites and for esophageal and hepatic cancers when compared with non-cirrhotic blacks.

    Systemic chemotherapy based on 5-fluorouracil (5-FU) is a standard treatment for unresectable or recurrent large intestinal cancer. Although hyperammonemia is a known side effect of 5-FU that can cause serious pathological conditions, only a few cases have been reported. We describe 4 cases of 5-FU-related hyperammonemia with impairment of consciousness in patients who received 5-FU chemotherapy for large intestinal cancer with multiple liver metastases. Hemodialysis was effective in 1 severe case. There have been no detailed reports on the use of hemodialysis for hyperammonemia caused by 5-FU. Renal dysfunction is considered to be a risk factor for hyperammonemia caused by 5-FU and it is necessary to pay particular attention in patients with renal dysfunction who receive chemotherapy with 5-FU. Here we summarize our cases together with 16 previously reported cases of hyperammonemia caused by 5-FU in Japan.

    Primary liver cancer, which includes hepatocellular carcinoma (HCC), intrahepatic cholangiocarcinoma (ICC) and fibrolamellar HCC, is one of the most common malignancies and the third leading cause of cancer-associated mortality, worldwide. Despite the development of novel therapies, the prognosis of liver cancer patients remains extremely poor. Thus, investigation of the genetic background and molecular mechanisms underlying the development and progression of this disease has gained significant attention. The Notch signaling pathway is a crucial determinant of cell fate during development and disease in several organs. In the liver, Notch signaling is involved in biliary tree development and tubulogenesis, and is also significant in the development of HCC and ICC. These findings suggest that the modulation of Notch pathway activity may have therapeutic relevance. The present review summarizes Notch signaling during HCC and ICC development and discusses the findings of recent studies regarding Notch expression, which reveal novel insights into its function in liver cancer progression.

    Summary The knowledge and understanding of all aspects of liver cancer [this including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (iCCA)] have experienced a major improvement in the last decades. New laboratory technologies have identified several molecular abnormalities that, at the very end, should provide an accurate stratification and optimal treatment of patients diagnosed with liver cancer. The seminal discovery of the TP53 hotspot mutation [1,2] was an initial landmark step for the future classification and treatment decision using conventional clinical criteria blended with molecular data. At the same time, the development of ultrasound, computed tomography (CT) and magnetic resonance (MR) has been instrumental for earlier diagnosis, accurate staging and treatment advances. Several treatment options with proven survival benefit if properly applied are now available. Major highlights include: i) acceptance of liver transplantation for HCC if within the Milan criteria [3], ii) recognition of ablation as a potentially curative option [4,5], iii) proof of benefit of chemoembolization (TACE), [6] and iv) incorporation of sorafenib as an effective systemic therapy [7]. These options are part of the widely endorsed BCLC staging and treatment model (Fig. 1) [8,9]. This is clinically useful and it will certainly keep evolving to accommodate new scientific evidence. This review summarises the data which are the basis for the current recommendations for clinical practice, while simultaneously exposes the areas where more research is needed to fulfil the still unmet needs (Table 1).

    Primary and metastatic liver tumors are an increasing global health problem, with hepatocellular carcinoma (HCC) now being the third leading cause of cancer-related mortality worldwide. Systemic treatment options for HCC remain limited, with Sorafenib as the only prospectively validated agent shown to increase overall survival. Surgical resection and/or transplantation, locally ablative therapies and regional or locoregional therapies have filled the gap in liver tumor treatments, providing improved survival outcomes for both primary and metastatic tumors. Minimally invasive local therapies have an increasing role in the treatment of both primary and metastatic liver tumors. For patients with low volume disease, these therapies have now been established into consensus practice guidelines. This review highlights technical aspects and outcomes of commonly utilized, minimally invasive local therapies including laparoscopic liver resection (LLR), radiofrequency ablation (RFA), microwave ablation (MWA), high-intensity focused ultrasound (HIFU), irreversible electroporation (IRE), and stereotactic body radiation therapy (SBRT). In addition, the role of combination treatment strategies utilizing these minimally invasive techniques is reviewed. PMID:25610708

    The liver is the most common site of distant metastases in patients with colorectal cancer. Surgery represents the mainstream for curative treatment of colorectal cancer liver metastases (CRCLM) with long-term survival up to 58 and 36 % at 5 and 10 years, respectively. Despite advances on diagnosis, staging and surgical strategies, 60-70 % of patients will develop recurrence of the disease even after R0 resection of CRCLM. Tumor staging, prognosis, and therapeutic approaches for cancer are most often based on the extent of involvement of regional lymph nodes (LNs) and, to a lesser extent, on the invasion of regional lymphatic vessels draining the primary tumor. For CRCLM, the presence of intra hepatic lymphatic and blood vascular dissemination has been associated with an increased risk of intra hepatic recurrence, poorer disease-free and overall survival after liver resection. Also, several studies have reviewed the role of surgery in the patient with concomitant CRCLM and liver pedicle LN metastasis. Although pedicle LN involvement is related to worst survival rates, it does not differentiate patients that will relapse from those that will not. This review aims to briefly describe the anatomy of the liver's lymphatic drainage, the incidence of intrahepatic lymphatic invasion and hilar lymph node involvement, as well as their clinical impact in CRCLM. A better understanding of the role of liver lymphatic metastasis might, in the near future, impact the strategy of systemic therapies after liver resection as for primary colorectal tumors.

    Since liver cancer seriously threatens human health, it is very urgent to explore an effective method for diagnosing liver cancer early. In this study, we investigated the structure differences of IR spectra between neoplastic liver cells and normal liver cells. The major differences of absorption bands were observed between liver cancer cells and normal liver cells, the values of A2955/A2921, A1744/A1082, A1640/A1535, H1121/H1020 might be potentially useful factors for distinguishing liver cancer cells from normal liver cells. Curve fitting also provided some important information on structural differences between malignant and normal liver cancer cells. Furthermore, IR spectra combined with hierarchical cluster analysis could make a distinction between liver cancer cells and normal liver cells. The present results provided enough cell basis for diagnosis of liver cancer by FTIR spectroscopy, suggesting FTIR spectroscopy may be a potentially useful tool for liver cancer diagnosis.

    In this paper, we present the successful therapeutic approach of unresectable liver metastases in a patient with rectal cancer.A 63-year-old male underwent endoscopic polypectomy followed by rectosigmoid resection for an adenocarcinoma of the rectum diagnosed in pT2N0 stage. The angio-computed tomography (CT) revealed four metastatic hepatic nodules ranging from 12 to 130 mm in diameter. After one cure of trans-arterial chemoembolization (TACE) with lipiodol and 5-fluorouracil, combined with FOLFOX4 + capecitabine systemic chemotherapy, the diameter of all hepatic nodules decreased to half size, at 6 months after TACE. Further curative surgical hepatic metastasectomy was done and complete pathologic response was obtained. The patient is free of recurrences and metastases after 26 months of follow-up.This representative case shows that an efficient trans-disciplinary approach could lead to successful therapeutic management even in patients with advanced-staged colorectal carcinomas.

    The mechanism of the anti-colorectal cancer (CRC) activity of the omega-3 fatty acid eicosapentaenoic acid (EPA) is not understood. We tested the hypothesis that EPA reduces expression of chemokine C-C motif ligand 2 (CCL2), a pro-inflammatory chemokine with known roles in metastasis. We measured CCL2 in clinical samples from a randomized trial of EPA in patients undergoing liver surgery for CRC liver metastasis (LM) and preclinical models. Genome-wide transcriptional profiling of tumors from EPA-treated patients was performed. EPA decreased CCL2 synthesis by CRC cells in a dose-dependent manner. CCL2 was localized to malignant epithelial cells in human CRCLM. EPA did not reduce CCL2 content in human or mouse tumors compare to control. However, EPA treatment was associated with decreased plasma CCL2 levels compared with controls (P=0.04). Reduction in plasma CCL2 following EPA treatment predicted improved disease-free survival (HR 0.32; P=0.003). Lack of ‘CCL2 response’ was associated with a specific CRCLM gene expression signature. In conclusion, reduction in plasma CCL2 in patients with CRCLM treated with EPA predicts better clinical outcome and a specific tumor gene expression profile. Further work is needed to validate CCL2 as a therapeutic response biomarker for omega-3 fatty acid treatment of CRC patients. PMID:27058904

    Cachexia is a devastating process especially in pancreatic cancer patients and contributes to their poor survival. We attempted to clarify the pathological and molecular changes that occur in the liver during the development of cachexia. Using immunohistochemistry we investigated the infiltration of inflammatory mononuclear cells in liver biopsies of pancreatic cancer patients with or without cachexia, and the potential relevance of the cells for the nutritional and inflammatory status. Additionally, these findings were compared with the patients' clinical parameters. We found a significantly higher amount of CD68 immunoreactive macrophages in liver cross sections of patients with pancreatic cancer and cachexia. The number of CD68-positive macrophages was significantly inversely correlated with the nutritional status. Additionally, in these CD68-positive areas a significant increase in IL-6 and IL-1 immunoreactive cells was localized. Moreover, we found significantly increased areas of CD68-positive macrophages in liver biopsies of patients with a more dedifferentiated (aggressive) grading of the tumor. In conclusion, these results suggest that a crucial interaction between the tumor, PBMCs, and the liver may play a central role in the development and regulation of cachexia. Furthermore, pancreatic cancer may be able to alter systemic organ function even without obvious metastatic disease. PMID:19148509

    ABSTRACT Therapies for liver cancer particularly those including radiation are still inadequate. Inhibiting the stress response machinery is an appealing anti-cancer and radiosensitizing therapeutic strategy. Heat-shock-protein-90 (HSP90) is a molecular chaperone that is a prominent effector of the stress response machinery and is overexpressed in liver cancer cells. HSP90 client proteins include critical components of pathways implicated in liver cancer cell survival and radioresistance. The effects of a novel non-geldanamycin HSP90 inhibitor, ganetespib, combined with radiation were examined on 3 liver cancer cell lines, Hep3b, HepG2 and HUH7, using in vitro assays for clonogenic survival, apoptosis, cell cycle distribution, γH2AX foci kinetics and client protein expression in pathways important for liver cancer survival and radioresistance. We then evaluated tumor growth delay and effects of the combined ganetespib-radiation treatment on tumor cell proliferation in a HepG2 hind-flank tumor graft model. Nanomolar levels of ganetespib alone exhibited liver cancer cell anti-cancer activity in vitro as shown by decreased clonogenic survival that was associated with increased apoptotic cell death, prominent G2-M arrest and marked changes in PI3K/AKT/mTOR and RAS/MAPK client protein activity. Ganetespib caused a supra-additive radiosensitization in all liver cancer cell lines at low nanomolar doses with enhancement ratios between 1.33–1.78. These results were confirmed in vivo, where the ganetespib-radiation combination therapy produced supra-additive tumor growth delay compared with either therapy by itself in HepG2 tumor grafts. Our data suggest that combined ganetespib-radiation therapy exhibits promising activity against liver cancer cells, which should be investigated in clinical studies. PMID:26980196

    Purpose To assess the feasibility and effectiveness of quantitative intravoxel incoherent motion (IVIM) of Diffusion-weighted imaging (DWI) in the assessment of liver metastases treated with targeted chemotherapy agents. Methods 12 patients with unresectable liver metastases from colorectal cancer were enrolled and received neoadjuvant FOLFIRI (5-fluorouracil, leucovorin, irinotecan) plus bevacizumab therapy. DWI was performed for 36 metastases at baseline and after 14 days from starting the treatment. In addition to the basic IVIM metrics, the product between pseudo-diffusivity and perfusion fraction was considered as a descriptor roughly analogous to the flow. Median diffusion parameters of Region of Interest (ROI) were used as representative values for each lesion. Normalized parameters in comparison with the median value of spleen were also collected. The percentual change of the diffusion parameters was calculated. The response to chemotherapy was evaluated according the Response Evaluation Criteria in Solid Tumors (RECIST) as calculated on whole-body CT scan obtained three months after treatment. Mann Whitney test and Receiver operating characteristic (ROC) analysis were performed. Results 24 lesions were categorized as responding and 12 as not responding. There was no statistically significant difference among absolute and normalized diffusion parameters between the pretreatment and the post-treatment findings. Instead, the perfusion fraction (fp) values showed a statistical difference between responder and non-responder lesions: sensitivity and specificity of fp variation was 62% and 93%, respectively. Conclusions IVIM parameters represent a valuable tool in the evaluation of the anti-angiogenic therapy in patients with liver metastases from colorectal cancer. A percentage change of fp represents the most effective DWI marker in the assessment of tumor response. PMID:26566221

    In this paper, laser induced human serum Raman spectra of liver cancer are measured. The spectra differences in serum from normal people and liver disease patients are analyzed. For the typical spectrum of normal serum, there are three sharp Raman peaks and relative intensity of Raman peaks excited by 514.5nm is higher than that excited by 488.0nm. For the Raman spectrum of liver cancer serum there are no peaks or very weak Raman peaks at the same positions. Results from more than two hundred case measurements show that clinical diagnostic accuracy is 92.86%. And then, the liver fibrosis and liver cirrhosis are studied applying the technology of LIF. To liver cirrhosis, the shape of Raman peak is similar to normal and fluorescence spectrum is similar to that of liver cancer from statistic data. The experiment indicates that there is notable fluorescence difference between the abnormal and normal liver tissue and have blue shift in fluorescence peak. Except for human serum, we use rats serum for researching either. Compared with results of path al examination, we analyze the spectra of normal cases, hepatic fibrosis and hepatocirrhosis respectively in an attempt to find some difference between them. Red shift of fluorescence peak is observed with disease evolution using 514.5nm excitation of an Ar-ion laser. However, no distinct changes happen with 488.0nm excitation. These results have important reference values to explore the method of laser spectrum diagnosis.

    The liver is one of the commonest sites of metastatic involvement in breast cancer, usually evident as focal lesions on imaging tests. Rarely, the pattern of metastatic spread is so diffuse that it remains radiologically occult. Such patients usually present with signs of hepatic insufficiency without any focal lesions on liver imaging. In such cases, liver biopsy is required to make a definitive diagnosis. We report a case of a 56-year-old postmenopausal woman with metastatic breast cancer who presented with subacute progressive liver failure. Repeated imaging of the liver was normal or non-descript. Liver biopsy finally established the diagnosis of intrasinusoidal metastases from breast cancer.

    Selective estrogen receptor modulator (SERM)-associated nonalcoholic fatty liver disease (NAFLD) might be related to treatment efficacy in patients with breast cancer because of circulating estrogen antagonism. The aim of the study was to investigate the relationship between NAFLD and survival outcomes in patients with breast cancer who were treated with tamoxifen or toremifene. This single-center, retrospective, cohort study included 785 eligible patients who received tamoxifen or toremifene, after curative resection for breast cancer, at the Sun Yat-sen University Cancer Center between January 2005 and December 2009. Data were extracted from patient medical records. All patients underwent abdominal ultrasonography, at least once, at baseline and at the annual follow-up. Patients who were diagnosed with NAFLD on ultrasonography were classified into the NAFLD or the non-NAFLD arm at the 3-year follow-up visit. Univariate and multivariate Cox regression analyses were conducted to evaluate any associations between NAFLD and disease-free survival (DFS) or overall survival (OS). One hundred fifty-eight patients were diagnosed with NAFLD. Patients who developed NAFLD had better DFS and OS compared with those who did not. Univariate analyses revealed that the 5-year DFS rates were 91.56% and 85.01% for the NAFLD and non-NAFLD arms, respectively (hazard ratio [HR], 0.59; 95% confidence interval [CI], 0.37-0.96; log-rank P = 0.032). The 5-year OS rates were 96.64% and 93.31% for the NAFLD and non-NAFLD arms, respectively (HR, 0.39; 95% CI, 0.16-0.99; log-rank P = 0.039). Multivariate analysis revealed that NAFLD was an independent prognostic factor for DFS, improving the DFS rate by 41% compared with that in the non-NAFLD arm (HR, 0.59; 95% CI, 0.36-0.96; P = 0.033). SERM-associated NAFLD was independently associated with improved DFS and might be useful for predicting treatment responses in breast cancer patients treated with SERMs. PMID:26448028

    Human serum has been widely employed clinically for diagnosing various fatal diseases. However, the concentration of most proteins in human serum is too low to be directly measured using normal analytical methods. In order to obtain reliable analytical results from proteomic analysis of human serum, appropriate sample preparation is essential. A combined off-line analytical technique of gel chromatography and matrix-assisted laser desorption ionization/time of flight mass spectrometry (MALDI-TOF MS) has been successfully established to separate proteins for MS analysis. Using these combined techniques, 176 mass signal peaks of proteins/peptides were found in 6 of 18 fractions from normal male serum (NMS) in the presence of buffer consisting of NH4HCO3 and acetonitrile. A simple gel chromatography column packed with Sephadex G-50 removed most signal-suppressing compounds such as salts and high abundance proteins (HAP). The molecular mass to charge (m/z) ratios of differential peptides revealed in serum of male patient with liver-cancer (LCMPS) compared to NMS were 5365, 5644 and 6462, and these peptides can be used as biomarkers to clinically diagnose liver-cancer. The simple and convenient chromatographic method described here is not only superior to recently described HPLC separation for MS analysis, but also reveals many novel and significant serum biomarkers for the clinical diagnosis of various diseases.

    Cancer is the third most common cause of death (after cardiovascular disease and infection) for patients who have a functioning kidney allograft. Kidney and liver transplant recipients have similar cancer risks because of immunosuppression but different risks because of differences in primary diseases that cause renal and hepatic failure and the inherent behavior of cancers in the liver. There are 4 types of cancer that may develop in liver allograft recipients: (1) recurrent cancer, (2) donor-transmitted cancer, (3) donor-derived cancer, and (4) de novo cancer. Identification of potential donor cancer transmission may occur at postmortem examination of a deceased donor or when a probable donor-transmitted cancer is identified in another recipient. Donor-transmitted cancer after liver transplant is rare in Australia, the United Kingdom, and the United States. Aging of the donor pool may increase the risk of subclinical cancer in donors. Liver transplant recipients have a greater risk of de novo cancer than the general population, and risk factors for de novo cancer in liver transplant recipients include primary sclerosing cholangitis, alcoholic liver disease, smoking, and increased age. Liver transplant recipients may benefit from cancer screening because they have a high risk, are clearly identifiable, and are under continuous medical supervision.

    Recent research efforts in stem cell and cancer biology have put forth a "stem cell model of carcinogenesis" which stipulates that the capability to maintain tumor formation and growth specifically resides in a small population of cells called cancer stem cells. The stem cell-like characteristics of these cells, including their ability to self-renew and differentiate; and their limited number within the bulk of the tumor mass, are believed to account for their capability to escape conventional therapies. In the past few years, the hypothesis of stem cell-driven tumorigenesis in liver cancer has received substantial support from the recent ability to identify and isolate a subpopulation of liver cancer cells that is not only able to initiate tumor growth, but also serially establish themselves as tumor xenografts with high efficiency and consistency. In this review, stem cell biology that contributes to explain tumor development in the particular context of liver cancer will be discussed. We will begin by briefly considering the knowledge available on normal liver stem cells and their role in tissue renewal and regeneration. We will then summarize the current scientific knowledge of liver cancer stem cells, discuss their relevance to the diagnosis and treatment of the disease and consider the outstanding challenges and potential opportunities that lie ahead of us.

    Fever of unknown origin (FUO) remains a challenging clinical problem, namely in patients with cancer. In cancer patients, FUO may be due to the cancer itself, as it is the case of hematological malignancies; digestive tumors (colon cancer, liver metastases) are significantly associated with FUO and infection can be demonstrated in some cases. Prevention with G-CSF and empirical antimicrobial therapy are essential approaches for the management of FUO in cancer patients. New diagnostic approaches, such as PET imaging, should be further evaluated in cancer patients with FUO. PMID:26995082

    This review describes the pathological classification of pediatric liver cancer types and subtypes proposed at the recent international symposium (March 2011, Los Angeles, USA) and meetings involving pathologists serving as central reviewers for the Children's Oncology Group, Société Internationale d'Oncologie Pédiatrique, Gesellschaft für Pädiatrische Onkologie und Hämatologie, or Japanese Study Group for Pediatric Liver Tumors, and pediatric oncologists/surgeons specializing in liver cancers, as well as immunohistochemical panels, recommendations for submission, sampling and evaluation of diagnostic specimens. The pathological classification is intended to be standardized and clinically meaningful, thus improving future patient management and prognosis. The most common pediatric liver cancer is hepatoblastoma (HBL). HBL has two types, the wholly epithelial type and the mixed epithelial and mesenchymal (MEM) type. The wholly epithelial type was subdivided into well-differentiated fetal (pure fetal with low mitotic activity), crowded fetal (mitotically active), embryonal, epithelial mixed, small cell undifferentiated, and cholangioblastic. A macrotrabecular pattern and a pleomorphic epithelial pattern were recognized as supplemental features of epithelial components. The MEM type was subdivided into MEM without teratoid features and MEM with teratoid features. Other liver cancers in children were divided into hepatocellular carcinoma (classic hepatocellular carcinoma and fibrolamellar carcinoma) and hepatocellular malignant tumor not otherwise specified. This classification is basically applied to pretreatment specimens; the evaluation of post-chemotherapy specimens will be the subject of further studies.

    Abstract In this paper, we present the successful therapeutic approach of unresectable liver metastases in a patient with rectal cancer. A 63-year-old male underwent endoscopic polypectomy followed by rectosigmoid resection for an adenocarcinoma of the rectum diagnosed in pT2N0 stage. The angio-computed tomography (CT) revealed four metastatic hepatic nodules ranging from 12 to 130 mm in diameter. After one cure of trans-arterial chemoembolization (TACE) with lipiodol and 5-fluorouracil, combined with FOLFOX4 + capecitabine systemic chemotherapy, the diameter of all hepatic nodules decreased to half size, at 6 months after TACE. Further curative surgical hepatic metastasectomy was done and complete pathologic response was obtained. The patient is free of recurrences and metastases after 26 months of follow-up. This representative case shows that an efficient trans-disciplinary approach could lead to successful therapeutic management even in patients with advanced-staged colorectal carcinomas.

    Abstract Double primary liver cancer (DPLC) is a special type of clinical situation. As such, a detailed analysis of the surgical management and prognosis of patients with DPLC is lacking. The objective of the current study was to define the management and outcome of patients undergoing surgery for DPLC at a major hepatobiliary center. A total of 87 patients treated by surgical resection at the Eastern Hepatobiliary Surgery Hospital from January 1st, 2007 to October 31st, 2013 who had DPLC demonstrated by final pathological diagnosis were identified. Among these, 50 patients had complete clinical and prognostic data. Demographic and tumor characteristics as well as the prognosis were analyzed. The proportion of hepatitis B surface antigen (HBsAg) (+) and hepatitis B virus e antigen (HBeAg) (+), HBsAg (+), and HBeAg (−) hepatocirrhosis in all patients was 21.84%, 67.82%, and 63.22%, respectively. Incidental findings accounted for 58.62% of patients; among those who had symptoms, the main symptom was abdominal pain (31.03%). Nonanatomic wedge resection was the main operative approach (62.07%). Postoperatively, the main complications included seroperitoneum (11.49%), hypoproteinemia (10.34%), and pleural effusion (8.05%). Factors associated with disease-free survival (DFS) included intrahepatic cholangiocarcinoma (ICC) tumor size (P = 0.002) and use of postoperative prophylactic transcatheter arterial chemoembolization (TACE) treatment (P = 0.015). Meanwhile, hepatocellular carcinoma (HCC) size (P = 0.045), ICC size (P < 0.001), and liver function (including aspartate aminotransferase [P = 0.001] and r-glutamyl transferase [P < 0.001]) were associated with overall survival (OS). Hepatitis B virus (HBV)-related hepatitis or cirrhosis is also an important factor in the pathogenesis of DPLC and surgical treatment is safe for it with low complication rates. In addition, it is effective to prolong DFS that DPLC patients undergo postoperative

  9. Update in Cancer Chemotherapy: Gastrointestinal Cancer, Cancer of the Small Intestines, Gallbladder, Liver, and Esophagus

    This article updating cancer chemotherapy of gastrointestinal cancer completes the fivepart series begun in the April issue of the Journal. Treatment of cancer of the small intestine, the gallbladder and bile duct, primary cancer of the liver, and the esophagus are reviewed in this concluding article. Treatment of choice of cancer of the small intestine is surgical resection. Small bowel cancer is less responsive than gastric cancer to chemotherapy. While chemotherapy may produce temporary partial remissions in patients with gallbladder and bile duct cancer, there is no evidence that it produces longterm survival time. In primary liver cancer, surgery is the only curative treatment, but only 30 percent of patients are diagnosed with resectable lesions, and the surgical mortality rate is high. The most active single agents appear to be doxorubicin, fluorouracil, and neocarcinostatin. Data on combination chemotherapy are limited. With carcinoma of the esophagus, 95 percent of patients die of the condition. The standard treatment for locoregional disease is surgical resection and/or radiation therapy. Chemotherapy has been slow to develop; single-agent chemotherapy has been reported to be active in 15 percent of cases with durations of 2 to 5 months. Combination chemotherapy is so recent that data are incomplete as to long-term results of disease-free and total survival times, but polychemotherapy appears to be more effective than single agents. With earlier detection, prompt surgery, earlier chemotherapy, improved dose scheduling, and further exploration of combination therapy, better overall results with a major impact years later may be expected. Because of the lack of data, there remains uncertainty as to the place of chemotherapy in the treatment of gastrointestinal cancer. PMID:3531532

    Despite significant advances in medicine, liver cancer, predominantly hepatocellular carcinoma remains a major cause of death in the United States as well as the rest of the world. As limited treatment options are currently available to patients with liver cancer, novel preventive control and effective therapeutic approaches are considered to be reasonable and decisive measures to combat this disease. Several naturally occurring dietary and non-dietary phytochemicals have shown enormous potential in the prevention and treatment of several cancers, especially those of the gastrointestinal tract. Terpenoids, the largest group of phytochemicals, traditionally used for medicinal purposes in India and China, are currently being explored as anticancer agents in clinical trials. Terpenoids (also called “isoprenoids”) are secondary metabolites occurring in most organisms, particularly plants. More than 40 000 individual terpenoids are known to exist in nature with new compounds being discovered every year. A large number of terpenoids exhibit cytotoxicity against a variety of tumor cells and cancer preventive as well as anticancer efficacy in preclinical animal models. This review critically examines the potential role of naturally occurring terpenoids, from diverse origins, in the chemoprevention and treatment of liver tumors. Both in vitro and in vivo effects of these agents and related cellular and molecular mechanisms are highlighted. Potential challenges and future directions involved in the advancement of these promising natural compounds in the chemoprevention and therapy of human liver cancer are also discussed. PMID:21969877

    Background: Resection of colorectal cancer liver metastasis (CRCLM) with curative intent has long-term benefit in ∼40% of cases. Prognostic biomarkers are needed to improve clinical management and reduce futile surgeries. Expression of epidermal growth factor receptor (EGFR) and prostaglandin-endoperoxide synthase 2 (PTGS2; also known as cyclooxygenase-2) has been associated with carcinogenesis and survival. We investigated the prognostic value of EGFR and PTGS2 expression in patients with resected CRCLM. Methods: Formalin-fixed paraffin-embedded CRCLM tissue and corresponding primary tumour specimens from a multi-institutional cohort of patients who underwent liver resection between 1990 and 2010 were incorporated into tissue microarrays (TMAs). TMAs were stained for EGFR and PTGS2 by immunohistochemistry. The hazard rate ratio (HRR) for the association between expression in CRCLM and overall survival was calculated using a 500-fold cross-validation procedure. Results: EGFR and PTGS2 expression could be evaluated in 323 and 351 patients, respectively. EGFR expression in CRCLM was associated with poor prognosis (HRR 1.54; P<0.01) with a cross-validated HRR of 1.47 (P=0.03). PTGS2 expression was also associated with poor prognosis (HRR 1.60; P<0.01) with a cross-validated HRR of 1.63 (P<0.01). Expression of EGFR and PTGS2 remained prognostic after multivariate analysis with standard clinicopathological variables (cross-validated HRR 1.51; P=0.02 and cross-validated HRR 1.59; P=0.01, respectively). Stratification for the commonly applied systemic therapy regimens demonstrated prognostic value for EGFR and PTGS2 only in the subgroup of patients who were not treated with systemic therapy (HRR 1.78; P<0.01 and HRR 1.64; P=0.04, respectively), with worst prognosis when both EGFR and PTGS2 were highly expressed (HRR 3.08; P<0.01). Expression of PTGS2 in CRCLM was correlated to expression in patient-matched primary tumours (P=0.02, 69.2% concordance). Conclusions: EGFR

    Introduction: Transfusion support is vital to the management of patients with liver diseases. Repeated transfusions are associated with many risks such as transfusion-transmitted infection, transfusion immunomodulation, and alloimmunization. Materials and Methods: A retrospective data analysis of antibody screening and identification was done from February 2012 to February 2014 to determine the frequency and specificity of irregular red-cell antibodies in multitransfused liver disease patients. The clinical and transfusion records were reviewed. The data was compiled, statistically analyzed, and reviewed. Results: A total of 842 patients were included in our study. Alloantibodies were detected in 5.22% of the patients. Higher rates of alloimmunization were seen in patients with autoimmune hepatitis, cryptogenic liver disease, liver damage due to drugs/toxins, and liver cancer patients. Patients with alcoholic liver disease had a lower rate of alloimmunization. The alloimmunization was 12.7% (23/181) in females and 3.17% (21/661) in males. Antibodies against the Rh system were the most frequent with 27 of 44 alloantibodies (61.36%). The most common alloantibody identified was anti-E (11/44 cases, 25%), followed by anti-C (6/44 cases, 13.63%). Conclusion: Our findings suggest that alloimmunization rate is affected by underlying disease. Provision of Rh and Kell phenotype-matched blood can significantly reduce alloimmunization.

    OBJECTIVE To examine the outcome of simultaneous resection for rectal cancer with synchronous liver metastases. BACKGROUND One quarter of colorectal cancer patients will present with liver metastasis at the time of diagnosis. Recent studies have shown that simultaneous resections are safe and feasible for stage IV colon cancer. Limited data are available for simultaneous surgery in stage IV rectal cancer patients. METHODS One hundred ninety-eight patients underwent surgical treatment for stage IV rectal cancer. In 145 (73%) patients, a simultaneous procedure was performed. Fifty-three (27%) patients underwent staged liver resection. A subpopulation of 69 (35%) patients underwent major liver resection (3 segments or more) and 30 (44%) patients with simultaneous surgery. RESULTS The demographics of the 2 groups were similar. Complication rates were comparable for simultaneous or staged resections, even in the group subjected to major liver resection. Total hospital stay was significantly shorter for the simultaneously resected patients (P < .01). CONCLUSIONS Simultaneous resection of rectal primaries and liver metastases is a safe procedure in carefully selected patients at high-volume institutions, even if major liver resections are required.

    Primary liver cancer (hepatocellular carcinoma, or HCC) is associated with liver cirrhosis 60-80% of the time. Liver cancer is one of the most common malignancies in the world, with approximately 1,000,000 cases reported every year. About 80% of people with primary liver cancer are male. Although two-thirds of people have advanced liver disease when they seek medical help, one third of the patients have cancer that has not progressed beyond the liver. HCC may metastasize to the lung, bones, kidney, and many other organs. Surgical resection, liver transplantation, chemotherapy and radiation therapy are the foundation of current HCC therapies. However the outcomes are poor: the survival rate is almost zero for metastatic HCC patients. Molecular mechanisms of HCC metastasis need to be understood better and new therapies must be developed to selectively target to unique characteristics of HCC cell growth and metastasis. We have developed the "in vivo microscopy" to study the mechanisms that govern liver tumor cell spread through the microenvironment in vivo with real-time confocal near-infrared fluorescence imaging. A recently developed "in vivo flow cytometer" and optical imaging are used to assess liver tumor cell spreading and the circulation kinetics of liver tumor cells. A real- time quantitative monitoring of circulating liver tumor cells by the in vivo flow cytometer will be useful to assess the effectiveness of the potential therapeutic interventions.

    Abstract Nowadays, de novo malignancies have become an important cause of death after transplantation. According to the accumulation of cases with liver transplantation, the incidence of de novo gastric cancer is anticipated to increase among liver transplant recipients in the near future, especially in some East Asian countries where both liver diseases requiring liver transplantation and gastric cancer are major burdens. Unfortunately, there is limited information regarding the relationship between de novo gastric cancer and liver transplantation. Herein, we report a case of stage IIIc gastric cancer after liver transplantation for hepatocellular carcinoma, who was successfully treated by radical distal gastrectomy with D2 lymphadenectomy but died 15 months later due to tumor progression. Furthermore, we extract some lessons to learn from the case and review the literatures. The incidence of de novo gastric cancer following liver transplantations is increasing and higher than the general population. Doctors should be vigilant in early detection and control the risk factors causing de novo gastric cancer after liver transplantation. Curative gastrectomy with D2 lymphadenectomy is still the mainstay of treatment for such patients. Preoperative assessments, strict postoperative monitoring, and managements are mandatory. Limited chemotherapy could be given to the patients with high risk of recurrence. Close surveillance, early detection, and treatment of posttransplant cancers are extremely important and essential to improve the survival. PMID:26886605

    We present our initial experience with CyberKnife stereotactic body radiation therapy (SBRT) in a heavily pretreated group of patients with liver metastases and primary liver tumors. From October 2007 to June 2009, 48 patients were treated at the Philadelphia CyberKnife Center for liver metastases or primary liver tumors. We report on 30 patients with 41 discrete lesions (1–4 tumors per patient) who received an ablative radiation dose (BED ≥ 79.2 Gy10 = 66 Gy EQD2). The treatment goal was to achieve a high SBRT dose to the liver tumor while sparing at least 700 cc of liver from radiation doses above 15 Gy. Twenty-three patients were treated with SBRT for metastatic cancer to the liver; the remainder (n = 7) were primary liver tumors. Eighty-seven percent of patients had prior systemic chemotherapy with a median 24 months from diagnosis to SBRT; 37% had prior liver directed therapy. Local control was assessed for 28 patients (39 tumors) with 4 months or more follow-up. At a median follow-up of 22 months (range, 10–40 months), 14/39 (36%) tumors had documented local failure. A decrease in local failure was found with higher doses of SBRT (p = 0.0237); 55% of tumors receiving a BED ≤ 100 Gy10 (10/18) had local failure compared with 19% receiving a BED > 100 Gy10 (4/21). The 2-year actuarial rate of local control for tumors treated with BED > 100 Gy10 was 75% compared to 38% for those patients treated with BED ≤ 100 Gy10 (p = 0.04). At last follow-up, 22/30 patients (73%) had distant progression of disease. Overall, seven patients remain alive with a median survival of 20 months from treatment and 57 months from diagnosis. To date, no patient experienced persistent or severe adverse effects. Despite the heavy pretreatment of these patients, SBRT was well tolerated with excellent local control rates when adequate doses (BED > 100 Gy10) were used. Median survival was limited secondary to

    Liver transplantation (LT) is a major surgery performed on patients with end stage liver disease. Nutrition is an integral part of patient care, and protein-energy malnutrition is almost universally present in patients suffering from liver disease undergoing LT. Nutrition assessment of preliver transplant phase helps to make a good nutrition care plan for the patients. Nutrition status has been associated with various factors which are related to the success of liver transplant such as morbidity, mortality, and length of hospital stay. To assess the nutritional status of preliver transplant patients, combinations of nutrition assessment methods should be used like subjective global assessment, Anthropometry mid arm-muscle circumference, Bioelectrical impedance analysis (BIA) and handgrip strength.

    Drug-induced liver chemistry abnormalities, primarily transaminase elevations, are commonly observed in pazopanib-treated patients. This meta-analysis characterises liver chemistry abnormalities associated with pazopanib. Data of pazopanib-treated patients from nine prospective trials were integrated (N=2080). Laboratory datasets were used to characterise the incidence, timing, recovery and patterns of liver events, and subsequent rechallenge with pazopanib. Severe cases of liver chemistry abnormalities were clinically reviewed. Multivariate analyses identified predisposing factors. Twenty percent of patients developed elevated alanine aminotransferase (ALT) >3×ULN. Incidence of peak ALT >3-5×ULN, >5-8×ULN, >8-20×ULN and >20×ULN was 8%, 5%, 5% and 1%, respectively. Median time to onset for all events was 42days; 91% of events were observed within 18weeks. Recovery rates based on peak ALT >3-5×ULN, >5-8×ULN, >8-20×ULN and >20×ULN were 91%, 90%, 90% and 64%, respectively. Median time from onset to recovery was 30days, but longer in patients without dose interruption. Based on clinical review, no deaths were associated with drug-induced liver injury. Overall, 38% of rechallenged patients had ALT elevation recurrence, with 9-day median time to recurrence. Multivariate analysis showed that older age was associated with development of ALT >8×ULN. There was no correlation between hypertension and transaminitis. Our data support the current guidelines on regular liver chemistry tests after initiation of pazopanib, especially during the first 9 or 10weeks, and also demonstrate the safety of rechallenge with pazopanib.

    Background/Aims: Nonalcoholic fatty liver disease (NAFLD) has emerged as an important cause of chronic liver disease, cirrhosis, and hepatocellular carcinoma (HCC). The Barcelona Clinic Liver Cancer (BCLC) system is the preferred staging system to evaluate patients with HCC and links prognosis assessment with treatment recommendation. The aim of this retrospective study was to evaluate whether the BCLC staging system and its treatment algorithm are suitable for patients with HCC arising from NAFLD. Methods: Forty-two patients with HCC related to either to NAFLD or cryptogenic cirrhosis were retrieved retrospectively from 2 centers in Brazil. Patients were classified according to BCLC staging system. If the proposed HCC therapy could not be applied, the case was considered to represent deviations from the recommended BCLC guideline. Causes of treatment deviations were investigated. Results: There were 4 patients without evidence of cirrhosis according to liver biopsy and/or clinical evaluation. One (2%), 21 (50%), 10 (24%), 5 (12%), and 5 patients (12%) were classified initially to the very early (0), early (A), intermediate (B), advanced (C), and terminal (D) BCLC stages, respectively. Thirty-five patients (83%) were treated according to BCLC recommendations. There were 3 cases (of 5) of protocol deviation in BCLC C patients. The 1- and 2-year overall survival rates were 81% and 66%, respectively. Conclusions: The BCLC system is applied in most cases of NAFLD-related HCC cases. Deviation of BCLC is found more frequently in BCLC C stage patients. PMID:25268068

    AIM: To compare the therapeutic effect of three types of inter-ventional management for primary liver cancer. METHODS: A total of 468 patients with primary liver cancer were randomly allocated to the following three groups: 138 cases treated with chemotherapy alone using mitomycin C, adriamycin and 5-FU (group A); 158 cases treated with chemoembolization using lipiodol (group B); and 172 cases with chemoembolization using lipiodol and gelfoam (group C). All patients were angiographically and sonographically followed-up. RESULTS: In group C, 67.5% patients had AFP value decreased by > 50%, which was much higher than the 43.3% in group B and 32.2% in group A. Tumor size reduction by ≥ 50% occurred in 20.3% of patients in group A, 41.2% of patients in group B and 44.8% of patients in group C. The intergroup differences between group A and group B or C were significant (P < 0.01). The 1-year and 3-year survival rates were 20.5% ± 3.6% and 1.9% ± 2.4% for group A, 51.3% ± 4.4% and 10.1% ± 4.9% for group B, and 63.0% ± 2.4% and 13.9% ± 5.0% for group C, respectively. The differences between all three groups were significant (P < 0.05). The mean survival time for patients in groups A, B and C were 9.6 mo, 16.1 mo and 17.9 mo, respectively. CONCLUSION: Chemoembolization with lipiodol and gelfoam was the most effective therapy for primary liver cancer in this study. The position of the embolization should be far and middle sections of the hepatic artery, and the proximal section should be reserved as the route of the next intra-arterial chemoembolization.

  2. Chemotherapy for the conversion of unresectable colorectal cancer liver metastases to resection.

    2011-09-01

    Resection of colorectal liver metastases (CLM) is the ultimate aim of treatment strategies in most patients with liver-confined metastatic colorectal cancer. Long-term survival is possible in selected patients with initially resectable or unresectable CLM. As a majority of patients have unresectable liver disease at the outset, there is a clear role for chemotherapy to downstage liver disease making resection possible. Studies of systemic chemotherapy with or without biologic therapy in patients with unresectable CLM have resulted in increased response rates, liver resection rates and survival. A sound physiologic rationale exists for the use of hepatic arterial infusion (HAI) therapy. Studies have shown that HAI with floxuridine combined with systemic chemotherapy increases response rates and liver resection rates in those patients with initially unresectable CLM. Toxicity from preoperative chemotherapy, biologic therapy and HAI therapy may adversely affect hepatic resection but can be kept minimal with appropriate monitoring. All conversion strategies should be decided by a multidisciplinary team.

    Population-based evidence of the relative risk of cancer among heart, kidney, and liver transplant recipients from Asia is lacking. The Taiwan National Health Insurance Research Database was used to conduct a population-based cohort study of transplant recipients (n = 5396), comprising 801 heart, 2847 kidney, and 1748 liver transplant recipients between 2001 and 2012. Standardized incidence ratios and Cox regression models were used. Compared with the general population, the risk of cancer increased 3.8-fold after heart transplantation, 4.1-fold after kidney transplantation and 4.6-fold after liver transplantation. Cancer occurrence showed considerable variation according to transplanted organs. The most common cancers in all transplant patients were cancers of the head and neck, liver, bladder, and kidney and non-Hodgkin lymphoma. Male recipients had an increased risk of cancers of the head and neck and liver, and female kidney recipients had a significant risk of bladder and kidney cancer. The adjusted hazard ratio for any cancer in all recipients was higher in liver transplant recipients compared with that in heart transplant recipients (hazard ratio = 1.5, P = .04). Cancer occurrence varied considerably and posttransplant cancer screening should be performed routinely according to transplanted organ and sex. PMID:27196400

    The development of liver metastases is a common clinical entity in the clinical course of colorectal cancer. For patients with isolated liver involvement, surgical resection is the only treatment that can provide a chance of prolonged survival and cure. However, most of these patients are not initially eligible for the surgery. Selected patients with initially considered to have unresectable disease may become resectable after systemic (chemotherapy ± biological therapy) and loco-regional treatment modalities including hepatic arterial infusion. Patients who have colorectal liver metastases ideally should be referred to a multidisciplinary cancer care team in order to identify the most optimal management approach. PMID:26862487

    In this study liver cancer deaths that could be attributed to certain risk factors were calculated. Applying population attributable risk methodology, the attributable risk of liver cancer was estimated for alcohol use, hepatitis B viral exposure, and occupational and industrial exposures. We found that these three risk factors accounted for 38% of liver cancer mortality in Wisconsin; 29% was attributable to alcohol consumption, 7% to occupational exposures, and 2% to hepatitis B viral infection. More than half of liver cancer mortality, however, was not accounted for by the three risk factors studied.

  6. STAT3 activation in monocytes accelerates liver cancer progression

    PubMed Central

    2011-01-01

    Background Signal transducer and activator of transcription 3 (STAT3) is an important transcription factor ubiquitously expressed in different cell types. STAT3 plays an essential role in cell survival, proliferation, and differentiation. Aberrantly hyper-activated STAT3 signaling in cancer cells and in the tumor microenvironment has been detected in a wide variety of human cancers and is considered an important factor for cancer initiation, development, and progression. However, the role of STAT3 activation in monocytes in the development of HCC has not been well understood. Methods Immunohistochemical analysis of phosphorylated STAT3 was performed on tissue microarray from HCC patients. Using a co-culture system in vivo, HCC cell growth was determined by the MTT assay. In vivo experiments were conducted with mice given diethylinitrosamine (DEN), which induces HCC was used to investigate the role of STAT3 expression in monocytes on tumor growth. Real-time PCR was used to determine the expression of cell proliferation and cell arrest associated genes in the tumor and nontumor tissue from liver. Results Phosphorylated STAT3 was found in human hepatocellular carcinoma tissue samples and was expressed in tumor cells and also in monocytes. Phosphorylated STAT3 expression in monocyte was significantly correlated to advanced clinical stage of HCC and a poor prognosis. Using a co-culture system in vivo, monocytes promoted HCC cell growth via the IL-6/STAT3 signaling pathway. The STAT3 inhibitor, NSC 74859, significantly suppressed tumor growth in vivo in mice with diethylinitrosamine (DEN)-induced HCC. In this animal model, blockade of STAT3 with NSC 74859 induced tumor cell apoptosis, while inhibiting both tumor cells and monocytes proliferation. Furthermore, NSC 74859 treatment suppressed cancer associated inflammation in DEN-induce HCC. Conclusion Our data suggest constitutively activated STAT3 monocytes promote liver tumorigenesis in clinical patients and animal

    We are reporting a case of a patient with a previous history of colorectal cancer (CRC) and cirrhosis, who developed concurrent liver lesions consistent with hepatocellular carcinoma (HCC); a case which is unique due to the low incidence of multiple cancers, particularly HCC in the setting of previous advanced colorectal carcinoma along, in a cirrhotic liver. We will review the known literature on multiple cancer rates found in patients with known colorectal carcinoma. We will then outline this particular patient's presentation, followed by a discussion as to why the particular concurrent development of HCC in the setting of previous CRC is of note.

    2012-08-01

    We previously identified claudin-2 as a functional mediator of breast cancer liver metastasis. We now confirm that claudin-2 levels are elevated in liver metastases, but not in skin metastases, compared to levels in their matched primary tumors in patients with breast cancer. Moreover, claudin-2 is specifically expressed in liver-metastatic breast cancer cells compared to populations derived from bone or lung metastases. The increased liver tropism exhibited by claudin-2-expressing breast cancer cells requires claudin-2-mediated interactions between breast cancer cells and primary hepatocytes. Furthermore, the reduction of the claudin-2 expression level, either in cancer cells or in primary hepatocytes, diminishes these heterotypic cell-cell interactions. Finally, we demonstrate that the first claudin-2 extracellular loop is essential for mediating tumor cell-hepatocyte interactions and the ability of breast cancer cells to form liver metastases in vivo. Thus, during breast cancer liver metastasis, claudin-2 shifts from acting within tight-junctional complexes to functioning as an adhesion molecule between breast cancer cells and hepatocytes.

    Liver resection is the treatment of choice for patients with colorectal liver metastases (CLM). However, major resections are often required to achieve R0 resection, which are associated with substantial rates of morbidity and mortality. Maximizing the amount of residual liver gained increasing significance in modern liver surgery due to the high incidence of chemotherapy-associated parenchymal injury. This fact, along with the progressive expansion of resectability criteria, has led to the development of a surgical philosophy known as “parenchymal-sparing liver surgery” (PSLS). This philosophy includes a variety of resection strategies, either performed alone or in combination with ablative therapies. A profound knowledge of liver anatomy and expert intraoperative ultrasound skills are required to perform PSLS appropriately and safely. There is a clear trend toward PSLS in hepatobiliary centers worldwide as current evidence indicates that tumor biology is the most important predictor of intrahepatic recurrence and survival, rather than the extent of a negative resection margin. Tumor removal avoiding the unnecessary sacrifice of functional parenchyma has been associated with less surgical stress, fewer postoperative complications, uncompromised cancer-related outcomes and higher feasibility of future resections. The increasing evidence supporting PSLS prompts its consideration as the gold-standard surgical approach for CLM. PMID:27358673

    Anxiety is common in cancer patient populations, and must often initially be recognized and managed by cancer care professionals. This article reviews the recent oncology and mental health literature on anxiety. The aim is to help those involved in cancer patient care who are not specialists in mental health to understand the nature of anxiety, and discriminate morbid from normal anxiety. We review recent research into the association of anxiety with events during diagnosis and management of cancer, highlighting the importance of the meaning of events to an individual as an important factor in making people anxious. Lastly we review management strategies which might be used by cancer care professionals, in particular the importance of an awareness of specific patterns of communication which may alleviate or maintain anxiety for some cancer patients. © 2000 Cancer Research Campaign PMID:11044347

    Thirty patients with advanced liver cancer were treated by interstitial photodynamic therapy (PDT). These included 28 hepatocellular carcinoma and two adenocarcinoma, 19 primary tumors and 11 recurred follow other treatments. The diameter of tumors were 7-10cm in 13 cases and 10-16cm in 17 cases. In this study, an argon laser pumped dye laser system was used to give a CW laser beam at 630 nm which was split and coupled into there optical fibers. The patients were injected intravenously with photosensitizer hematoporphyrin derivative at a dose of 5mg/kg body weight 48 hours before PDT. Then the fibers were inserted into tumor by ultrasound- guided percutaneous puncture. The inserted irradiation points were spaced in entire tumor with the light release power 300mW and the irradiation time 12 minutes per point. Total 52 treatments were performed in 30 patients. Among them, 14 cases were treated only one time and 16 cases via 2-3 times. The follow-up was carried out in 25 cases for 12- 24 months. The results show that significant remission was 22 percent in those patients by only one treatment and 62 percent in those via 2 to 3 treatments. The shrink rate of tumor size was over 90 percent in five of six cases after treatment 3. The survival time has been over one year in 12 cases. No obvious change to be found for all patients in liver function test, renal function test and blood routine examination. The level of AFP indicated a descending trend after PDT. This work indicate that PDT is effective and safe for the treatment of large liver cancers including those recurred follow hepatic resection and those failed in hepatic artery infusion embolic chemotherapy.

    Abstract This study aimed to evaluate cancer risk and possible risk factors in patients diagnosed with empyema. A total of 31,636 patients with newly diagnosed empyema between January 1, 1999 and December 31, 2010 were included in this study. Standardized incidence ratios (SIRs) were calculated to compare the cancer incidence in these empyema patients to that in the general population. Adjusted hazard ratios were also calculated to investigate whether characteristics increased cancer risk. During the 12-year study period, 2,654 cancers occurred in 31,636 patients with empyema, yielding an SIR of 2.67 (95% confidence interval [CI] 2.57–2.78). We excluded cancer that occurred within 1 year to avoid surveillance bias. The cancer risk remained significantly increased (SIR 1.50, 95% CI 1.41–1.58). Specifically, patients with empyema had higher SIR of cancers of the head and neck (1.50, 95% CI 1.41–1.58), esophagus (2.56, 95% CI 1.92–3.33), stomach (1.49, 95% CI 1.16–1.89), liver and biliary tract (2.18, 95% CI 1.93–2.45), and lung and mediastinum (1.62, 95% CI 1.39–1.86). Age ≥ 60, male sex, diabetes mellitus, and liver cirrhosis were independent risk factors for cancer development. Our study demonstrates an increased incidence of cancer development in patients with empyema, and patients’ age ≥ 60, men, and those with diabetes mellitus and liver cirrhosis showed a higher incidence of developing cancer compared to the general population. The association between such kind of infection and secondary malignancy may be elucidated by further study. PMID:26945399

    Backgrounds/Aims Aggressive surgical resection for hepatic metastasis is validated, however, concomitant liver and lung metastasis in colorectal cancer patients is equivocal. Methods Clinicopathologic data from January 2008 through December 2012 were retrospectively reviewed in 234 patients with colorectal cancer with concomitant liver and lung metastasis. Clinicopathologic factors and survival data were analyzed. Results Of the 234 patients, 129 (55.1%) had synchronous concomitant liver and lung metastasis from colorectal cancer and 36 (15.4%) had metachronous metastasis. Surgical resection was performed in 33 patients (25.6%) with synchronous and 6 (16.7%) with metachronous metastasis. Surgical resection showed better overall survival in both groups (synchronous, p=0.001; metachronous, p=0.028). In the synchronous metastatic group, complete resection of both liver and lung metastatic lesions had better survival outcomes than incomplete resection of two metastatic lesions (p=0.037). The primary site of colorectal cancer and complete resection were significant prognostic factors (p=0.06 and p=0.003, respectively). Conclusions Surgical resection for hepatic and pulmonary metastasis in colorectal cancer can improve complete remission and survival rate in resectable cases. Colorectal cancer with concomitant liver and lung metastasis is not a poor prognostic factor or a contraindication for surgical treatments, hence, an aggressive surgical approach may be recommended in well-selected resectable cases.

    Colorectal cancer metastasis to the liver is a major cause of cancer-related death; however, the genes and pathways that govern this metastatic colonization event remain poorly characterized. Here, using a large-scale in vivo RNAi screen, we identified liver and red blood cell pyruvate kinase (PKLR) as a driver of metastatic liver colonization. PKLR expression was increased in liver metastases as well as in primary colorectal tumors of patients with metastatic disease. Evaluation of a murine liver colonization model revealed that PKLR promotes cell survival in the tumor core during conditions of high cell density and oxygen deprivation by increasing glutathione, the primary endogenous antioxidant. PKLR negatively regulated the glycolytic activity of PKM2, the major pyruvate kinase isoenzyme known to regulate cellular glutathione levels. Glutathione is critical for metastasis, and we determined that the rate-limiting enzyme of glutathione synthesis, GCLC, becomes overexpressed in patient liver metastases, promotes cell survival under hypoxic and cell-dense conditions, and mediates metastatic liver colonization. RNAi-mediated inhibition of glutathione synthesis impaired survival of multiple colon cancer cell lines, and pharmacological targeting of this metabolic pathway reduced colonization in a primary patient-derived xenograft model. Our findings highlight the impact of metabolic reprogramming within the niche as metastases progress and suggest clinical potential for targeting this pathway in colorectal cancer. PMID:26784545

    Colorectal cancer metastasizes predictably, with liver predominance in most cases. Because liver involvement has been shown to be a major determinant of survival in this population, liver-directed therapies are increasingly considered even in cases where there is (limited) extrahepatic disease. Unfortunately, these patients carry a known risk of recurrence in the liver regardless of initial therapy choice. Therefore, there is a demand for minimally invasive, non-surgical, personalized cancer treatments to preserve quality of life in the induction, consolidation, and maintenance phases of cancer therapy. This report aims to review evidence-based conceptual, pharmacological, and technological paradigm shifts in parenteral and percutaneous treatment strategies as well as forthcoming evidence regarding next-generation systemic, locoregional, and local treatment approaches for this patient population.

    Vinyl-chloride monomer (VCM), a human carcinogen, has caused angiosarcoma of the liver. Recent studies have shown that VCM exposure is associated with hepatocellular cancer. In Taiwanese studies, the majority of VCM-exposed workers with liver cancer had history of hepatitis B virus (HBV) infection. To determine the role of HBV on the development of liver cancer in the VCM-exposed workers, we conducted a case-control study from a previously established polyvinyl chloride (PVC) cohort consisting of 4096 male workers from six PVC polymerization plants. A total of 18 patients with liver cancer, and 68 control subjects matched for age and specific plant of employment were selected. Detailed history of the participants that included alcohol consumption status, cigarette use, occupation, and family history of chronic liver disease were obtained using an interviewer-administered questionnaire. When the HBV surface antigen (HBsAg)-negative subjects without history of tank-cleaning were used as the reference, the HBsAg-negative subjects with history of tank-cleaning demonstrated a 4.0-fold greater risk of liver cancer (95% confidence interval: 95% CI = 0.2-69.1). The HBsAg carriers without history of tank-cleaning revealed a 25.7-fold greater risk of liver cancer (95% CI = 2.9-229.4). Whereas the HBsAg carriers with history of tank-cleaning revealed the greatest risk (matched odds ratio (ORm) 396.0, 95% CI = 22.6 -infinity) of developing liver cancer among subjects with different VCM-exposure status and HBsAg status categories. Further analysis showed the interaction term was significant (P < .01). Therefore, our results suggest an interaction between occupational VCM exposure and HBV infection for the development of liver cancer.

    Purpose: To measure the intrabreath-hold liver motion and the intrafraction and interfraction reproducibility of liver position relative to vertebral bodies using an active breathing coordinator (ABC) in patients with unresectable liver cancer treated with hypofractionated stereotactic body radiation therapy (SBRT). Methods: Tolerability of ABC and organ motion during ABC was assessed using kV fluoroscopy in 34 patients. For patients treated with ABC, repeat breath-hold CT scans in the ABC breath-hold position were acquired at simulation to estimate the volumetric intrafraction reproducibility of the liver relative to the vertebral bodies. In addition, preceding each radiation therapy fraction, with the liver immobilized using ABC, repeat anteroposterior (AP) megavoltage verification images were obtained. Off-line alignments were completed to determine intrafraction reproducibility (from repeat images obtained before one treatment) and interfraction reproducibility (from comparisons of the final image for each fraction with the AP) of diaphragm position relative to vertebral bodies. For each image set, the vertebral bodies were aligned, and the resultant craniocaudal (CC) offset in diaphragm position was measured. Liver position during ABC was also evaluated from kV fluoroscopy acquired at the time of simulation, kV fluoroscopy at the time of treatment, and from MV beam's-eye view movie loops acquired during treatment. Results: Twenty-one of 34 patients were screened to be suitable for ABC. The average free breathing range of these patients was 13 mm (range, 5-1 mm). Fluoroscopy revealed that the average maximal diaphragm motion during ABC breath-hold was 1.4 mm (range, 0-3.4 mm). The MV treatment movie loops confirmed diaphragm stability during treatment. For a measure of intrafraction reproducibility, an analysis of 36 repeat ABC computed tomography (CT) scans in 14 patients was conducted. The average mean difference in the liver surface position was -0.9 mm, -0

    Nutritional therapy for cancer patients includes various objectives such as improvement of cachexia, elucidation of the mechanism of malnutrition, development of therapy for anorexia, nutrition support during chemotherapy or radiotherapy, and inhibition of tumor growth under controlled caloric intake. This review describes recent remarkable developments in nutritional therapy for cancer patients. Cytokines such as interleukin (IL)-1, IL-6, and tumor necrosis factor which induce proteolysis and lipolysis are involved in the cause of malnutrition and cachexia in cancer patients. IL-1 also plays a significant role in the development of cancer anorexia via direct action in the brain. For anorexia therapy, progestogens have been shown to improve appetite and food intake in cancer patients. Moreover, glutamine supplementation improves the host protein metabolism without enhancement of tumor growth during chemotherapy. Among the effects of caloric intake on anticancer therapy, AO-90, a methionine-free intravenous amino acid solution, has been shown to increase the antitumor effect of 5-fluorouracil in clinical studies. From these observations, recent progress in nutritional therapy for cancer patients has been remarkable. Further study of nutritional therapy is required in order to maintain or improve the quality of life of cancer patients in the future.

    Approximately half of patients with colorectal cancer present with liver metastases during the course of their disease, which directly affect prognosis and is responsible for two thirds of deaths related to the disease. In the last two decades the treatment of liver metastases from colorectal cancer (CRCLM) provided significant gain in survival when all treatment options are available to the patient. In this context, surgical treatment remains as the only chance of cure, with five-year survival rates of 25-58%. However, only 1/4 of the patients have resectable disease at diagnosis. For this reason, one of the key points in the current management of patients with CRCLM is the development of strategies that facilitate complete resection of liver lesions. The advent and refinement of ablative methods have expanded the possibilities of surgical therapy. The emergence of new chemotherapy regimens and the introduction of targeted therapies has provided high response rates and has permanently altered the management of these patients. The multimodal therapy and the involvement of different medical specialties has increasingly enabled CRCLM treatment to approached the ideal treatment, i.e., an individualized one. Based on an extensive review of literature and on experience from some of the most important specialized centers of Brazil, the São Paulo Liver Club began a process of multi-institutional discussions that resulted in the recommendations that follow. These recommendations, however, are not intended to be absolute, but useful tools in the therapeutic decision process for this complex group of patients.

    OBJECTIVE: To provide an approach to the care of liver transplant (LT) patients, a growing patient population with unique needs. METHODS: A literature search of PubMed for guidelines and review articles using the keywords “liver transplantation”, “long term complications” and “medical management” was conducted, resulting in 77 articles. RESULTS: As a result of being on immunosuppression, LT recipients are at increased risk of infections and must be screened regularly for metabolic complications and malignancies. DISCUSSION: Although immunosuppression is key to maintaining allograft health after transplantation, it comes with its own set of medical issues to follow. Physicians following LT recipients must be aware of the greater risk for hypertension, diabetes, dyslipidemia, renal failure, metabolic bone disease and malignancies in these patients, all of whom require regular monitoring and screening. Vaccination, quality of life, sexual function and pregnancy must be specifically addressed in transplant patients. PMID:24729996

These dietary natural products and their active components could affect the development and progression of liver cancer in various ways, such as inhibiting tumor cell growth and metastasis, protecting against liver carcinogens, immunomodulating and enhancing effects of chemotherapeutic drugs. This review summarizes the potential prevention and treatment activities of dietary natural products and their major bioactive constituents on liver cancer, and discusses possible mechanisms of action.

    Claudin-2 enhances breast cancer liver metastasis and promotes the development of colorectal cancers. The objective of our current study is to define the regulatory mechanisms controlling Claudin-2 expression in breast cancer cells. We evaluated the effect of several Src Family Kinase (SFK) inhibitors or knockdown of individual SFK members on Claudin-2 expression in breast cancer cells. We also assessed the potential effects of pan-SFK and SFK-selective inhibitors on the formation of breast cancer liver metastases. This study reveals that pan inhibition of SFK signaling pathways significantly elevated Claudin-2 expression levels in breast cancer cells. In addition, our data demonstrate that pan-SFK inhibitors can enhance breast cancer metastasis to the liver. Knockdown of individual SFK members reveals that loss of Yes or Fyn induces Claudin-2 expression; whereas, diminished Lyn levels impairs Claudin-2 expression in breast cancer cells. The Lyn-selective kinase inhibitor, Bafetinib (INNO-406), acts to reduce Claudin-2 expression and suppress breast cancer liver metastasis. Our findings may have major clinical implications and advise against the treatment of breast cancer patients with broad-acting SFK inhibitors and support the use of Lyn-specific inhibitors.

    Pitavastatin classically functions as a blood cholesterol-lowering drug. Previously, it was discovered with antiglioma stem cell properties through drug screening. However, whether it can be used for liver cancer cell therapy has never been reported. In this study, the cell viability and colony formation assay were utilized to analyze the cytotoxicity of pitavastatin on liver cancer cells. The cell cycle alteration was checked after pitavastatin treatment. Apoptosis-related protein expression and the effect of caspase inhibitor were also checked. The in vivo inhibitory effect of pitavastatin on the growth of liver tumor was also tested. It was found that pitavastatin inhibited growth and colony formation of liver cancer Huh-7 cells and SMMC7721 cells. It induced arrest of liver cancer cells at the G1 phase. Increased proportion of sub-G1 cells was observed after pitavastatin treatment. Pitavastatin promoted caspase-9 cleavage and caspase-3 cleavage in liver cancer cells. Caspase inhibitor Z-VAD-FMK reversed the cleavage of cytotoxic effect of pitavastatin. Moreover, pitavastatin decreased the tumor growth and improved the survival of tumor-bearing mice. This study suggested the antiliver cancer effect of the old drug pitavastatin. It may be developed as a drug for liver cancer therapy.

    The objective of this study was to observe the change in blood perfusion of liver cancer following argon-helium knife treatment with functional computer tomography perfusion imaging. Twenty-seven patients with primary liver cancer treated with argon-helium knife and were included in this study. Plain computer tomography (CT) and computer tomography perfusion (CTP) imaging were conducted in all patients before and after treatment. Perfusion parameters including blood flows, blood volume, hepatic artery perfusion fraction, hepatic artery perfusion, and hepatic portal venous perfusion were used for evaluating therapeutic effect. All parameters in liver cancer were significantly decreased after argon-helium knife treatment (p < 0.05 to all). Significant decrease in hepatic artery perfusion was also observed in pericancerous liver tissue, but other parameters kept constant. CT perfusion imaging is able to detect decrease in blood perfusion of liver cancer post-argon-helium knife therapy. Therefore, CTP imaging would play an important role for liver cancer management followed argon-helium knife therapy.

    AIM: To test the hypothesis that liver cirrhosis is associated with mobilization of hematopoietic progenitor cells. METHODS: Peripheral blood samples from 72 patients with liver cirrhosis of varying etiology were analyzed by flow cytometry. Identified progenitor cell subsets were immunoselected and used for functional assays in vitro. Plasma levels of stromal cell-derived factor-1 (SDF-1) were measured using an enzyme linked immunosorbent assay. RESULTS: Progenitor cells with a CD133+/CD45+/CD14+ phenotype were observed in 61% of the patients. Between 1% and 26% of the peripheral blood mononuclear cells (MNCs) displayed this phenotype. Furthermore, a distinct population of c-kit+ progenitor cells (between 1% and 38 % of the MNCs) could be detected in 91% of the patients. Additionally, 18% of the patients showed a population of progenitor cells (between 1% and 68% of the MNCs) that was characterized by expression of breast cancer resistance protein-1. Further phenotypic analysis disclosed that the circulating precursors expressed CXC chemokine receptor 4, the receptor for SDF-1. In line with this finding, elevated plasma levels of SDF-1 were present in all patients and were found to correlate with the number of mobilized CD133+ progenitor cells. CONCLUSION: These data indicate that in humans, liver cirrhosis leads to recruitment of various populations of hematopoietic progenitor cells that display markers of intrahepatic progenitor cells.

    Background: Statins (3-hydroxy-3-methylglutaryl coenzyme A reductase inhibitors) are widely prescribed to reduce cholesterol levels. Studies have suggested that statins are associated with reduced risk of liver cancer, but much of the evidence is from regions of the world with high liver cancer incidence rates. The current study examined the statins–liver cancer relationship in a low-rate region and examined the effects of preexisting liver disease and diabetes on that association. Methods: A nested case-control study was conducted within the United Kingdom’s Clinical Practice Research Datalink (CPRD). Persons diagnosed with primary liver cancer between 1988 and 2011 were matched to controls at a four-to-one ratio. Matches stratified on liver disease and on diabetes were also completed. Odds ratios (ORs) and 95% confidence intervals (CIs) for associations of statins with liver cancer were estimated using conditional logistic regression. Results: In total, 1195 persons with primary liver cancer were matched to 4640 control patients. Statin use was associated with a statistically significantly reduced risk of liver cancer (ORadj = 0.55, 95% CI = 0.45 to 0.69), especially among current users (ORadj = 0.53, 95% CI = 0.42 to 0.66). The reduced risk was statistically significant in the presence (ORadj = 0.32, 95% CI = 0.17 to 0.57) and absence of liver disease (ORadj = 0.65, 95% CI = 0.52 to 0.81) and in the presence (ORadj = 0.30, 95% CI = 0.21 to 0.42) and absence of diabetes (ORadj = 0.66, 95% CI = 0.51 to 0.85). Conclusions: In the current study in a low-rate area, statin use was associated with a statistically significantly reduced risk of liver cancer overall. Risk was particularly reduced among persons with liver disease and persons with diabetes, suggesting that statin use may be especially beneficial in persons at elevated risk of liver cancer.

    The current view of cancer progression highlights that cancer cells must undergo through a post-translational regulation and metabolic reprogramming to progress in an unfriendly environment. In here, the importance of neddylation modification in liver cancer was investigated. We found that hepatic neddylation was specifically enriched in liver cancer patients with bad prognosis. In addition, the treatment with the neddylation inhibitor MLN4924 in Phb1-KO mice, an animal model of hepatocellular carcinoma showing elevated neddylation, reverted the malignant phenotype. Tumor cell death in vivo translating into liver tumor regression was associated with augmented phosphatidylcholine synthesis by the PEMT pathway, known as a liver-specific tumor suppressor, and restored mitochondrial function and TCA cycle flux. Otherwise, in protumoral hepatocytes, neddylation inhibition resulted in metabolic reprogramming rendering a decrease in oxidative phosphorylation and concomitant tumor cell apoptosis. Moreover, Akt and LKB1, hallmarks of proliferative metabolism, were altered in liver cancer being new targets of neddylation. Importantly, we show that neddylation-induced metabolic reprogramming and apoptosis were dependent on LKB1 and Akt stabilization. Overall, our results implicate neddylation/signaling/metabolism, partly mediated by LKB1 and Akt, in the development of liver cancer, paving the way for novel therapeutic approaches targeting neddylation in hepatocellular carcinoma.

    Since the first liver transplantation in Spain was carried out in 1984, advances in surgical technique and immunosuppressive drugs have facilitated an increase in the number of transplants performed. The present study evaluates buccodental health in liver transplant patients. A cross-sectional descriptive study was made of a sample of patients subjected to liver transplantation in Príncipes de España Hospital (Bellvitge University Health Care Complex, L'Hospitalet de Llobregat, Barcelona--Spain). Information was collected relating to demographic characteristics, general clinical history, buccodental history and intraoral exploratory findings. A total of 53 individuals were evaluated (28 males and 25 females, with a mean age of 57.6 years). The mean time elapsed from transplantation was 3 years and 9 months. The most frequent indication for liver transplantation was liver cirrhosis due to hepatitis C virus (HCV) infection (49.1% of the global series). The most widely used immunosuppressors were cyclosporine and tacrolimus. The CAOD index of the series was 11.2. In relation to periodontal disease, 22% of the dentate patients showed gingival overgrowth, while half of those with teeth had gingival recessions, and 34% presented some type of dental mobility. The examination of the oral mucosa showed fissured tongue to be the most common disorder (39.6%), followed by saburral tongue (28.3%) and xerostomia (18.9%). Buccodental pathology in these patients is related to the use of immunosuppressor medication and other factors such as a lack of preventive measures. The findings of the present study point to the need for preventive treatments in this population group.

    Sarcopenia, characterized by a decline of skeletal muscle plus low muscle strength and/or physical performance, has emerged to be an important prognostic factor for advanced cancer patients. It is associated with poor performance status, toxicity from chemotherapy, and shorter time of tumor control. There is limited data about sarcopenia in cancer patients and associated factors. Moreover, the knowledge about the changes of muscle mass during chemotherapy and its impact to response and toxicity to chemotherapy is still lacking. This review aimed to provide understanding about sarcopenia and to emphasize its importance to cancer treatment.

    Liver transplant (LT) is a major surgical undertaking involving major fluid shifts, hemodynamic instability and metabolic derangements in a patient with preexisting liver failure and multisystemic derangements. Monitoring and organ support initiated in the preoperative phase is continued intraoperatively and into the postoperative phase to ensure an optimal outcome. As cardiovascular events are the leading cause of non-graft related death among LT recipients, major emphasis is placed on cardiovascular monitoring. The other essential monitoring are the continuous assessment of coagulapathy, extent of metabolic derangements, dyselectrolytemis and intracranial pressure monitoring in patients with fulminant hepatic failure. The type and extent of monitoring differs with need according to preexisting child status of the patient and the extent of systemic derangements. It also varies among transplant centers and is mainly determined by individual or institutional practices.

    There is controversy regarding some aspects of hepatitis C virus (HCV) infection-associated liver steatosis, and their relationship with body fat stores. It has classically been found that HCV, especially genotype 3, exerts direct metabolic effects which lead to liver steatosis. This supports the existence of a so called viral steatosis and a metabolic steatosis, which would affect HCV patients who are also obese or diabetics. In fact, several genotypes exert metabolic effects which overlap with some of those observed in the metabolic syndrome. In this review we will analyse the pathogenic pathways involved in the development of steatosis in HCV patients. Several cytokines and adipokines also become activated and are involved in “pure” steatosic effects, in addition to inflammation. They are probably responsible for the evolution of simple steatosis to steatohepatitis, making it difficult to explain why such alterations only affect a proportion of steatosic patients.

    There is increasing evidence that thrombocytosis is associated with tumor invasion and metastasis formation. It was shown in several solid tumor types that thrombocytosis prognosticates cancer progression. The aim of this study was to evaluate preoperative thrombocytosis as a potential prognostic biomarker in isolated metastases, in patients with liver metastasis of colorectal cancer (mCRC). Clinicopathological data of 166 patients with mCRC who had surgical resection between 2001 and 2011 were collected retrospectively. All primary tumors have been already resected. The platelet count was evaluated based on the standard preoperative blood profile. The patients were followed-up on average for 28 months. Overall survival (OS) of patients with thrombocytosis was significantly worse both in univariate (HR = 3.00, p = 0.03) and in multivariate analysis (HR = 4.68, p = 0.056) when adjusted for gender, age, tumor size and surgical margin. Thrombocytosis was also a good prognosticator of disease-free survival (DFS) with HR = 2.7, p = 0.018 and nearly significant in multivariate setting (HR = 2.26, p = 0.073). The platelet count is a valuable prognostic marker for the survival in patients with mCRC.

    Liver cancer is the third most common cancer type and the second leading cause of deaths in men. Large population studies have demonstrated remarkable gender disparities in the incidence and the cumulative risk of liver cancer. A number of emerging risk factors regarding metabolic alterations associated with obesity, diabetes and dyslipidemia have been ascribed to the progression of non-alcoholic fatty liver diseases (NAFLD) and ultimately liver cancer. The deregulation of fat metabolism derived from excessive insulin, glucose, and lipid promotes cancer-causing inflammatory signaling and oxidative stress, which eventually triggers the uncontrolled hepatocellular proliferation. This review presents the current standing on the gender differences in body fat compositions and their mechanistic linkage with the development of NAFLD-related liver cancer, with an emphasis on genetic, epigenetic and microRNA control. The potential roles of sex hormones in instructing adipocyte metabolic programs may help unravel the mechanisms underlying gender dimorphism in liver cancer and identify the metabolic targets for disease management.

    The liver is an important organ with specific functions that influence directly on the nutritional and physiological status of every person. At the presence of any illness or injury in this organ, liver cirrhosis is always its final phase. In this pathology, patients present carbohydrate utilization and storage diminishment, as well as protein and fat catabolism increase. This situation, plus a low ingest and a bad nutrient absorption, results in a high prevalence of malnutrition. Many studies prove the importance of an opportune nutritional treatment in these patients, bringing general benefits and improving their quality of life. It's important to considerate the possible nutritional risks and deficiencies that could appear in the course of the cirrhosis to take opportune actions. The nutritional assessment and treatment is transcendental both in compensated phase (without complications) and in decompensated phase (with complications) of the illness.

    We investigated glutathione level, activities of selenium independent GSH peroxidase, selenium dependent GSH peroxidase, GSH S-transferase, GSH reductase and the rate of lipid peroxidation expressed as the level of malondialdehyde in liver tissues obtained from patients diagnosed with cirrhosis or hepatocellular carcinoma. GSH level was found to be lower in malignant tissues compared to adjacent normal tissues and it was higher in cancer than in cirrhotic tissue. Non-Se-GSH-Px activity was lower in cancer tissue compared with adjacent normal liver or cirrhotic tissue, while Se-GSH-Px activity in cancer was found to be similar to its activity in cirrhotic tissue and lower compared to control tissue. An increase in GST activity was observed in cirrhotic tissue compared with cancer tissue, whereas the GST activity in cancer was lower than in adjacent normal tissue. The activity of GSH-R was similar in cirrhotic and cancer tissues, but higher in cancer tissue compared to control liver tissue. An increased level of MDA was found in cancer tissue in comparison with control tissue, besides its level was higher in cancer tissue than in cirrhotic tissue. Our results show that the antioxidant system of cirrhosis and hepatocellular carcinoma is severely impaired. This is associated with changes of glutathione level and activities of GSH-dependent enzymes in liver tissue. GSH and enzymes cooperating with it are important factors in the process of liver diseases development.

    Prognosis of patients with cirrhosis and hepatocellular carcinoma (HCC) depends on both residual liver function and tumor extension. The CLIP score includes Child-Pugh stage, tumor morphology and extension, serum alfa-fetoprotein (AFP) levels, and portal vein thrombosis. We externally validated the CLIP score and compared its discriminatory ability and predictive power with that of the Okuda staging system in 196 patients with cirrhosis and HCC prospectively enrolled in a randomized trial. No significant associations were found between the CLIP score and the age, sex, and pattern of viral infection. There was a strong correlation between the CLIP score and the Okuda stage. As of June 1999, 150 patients (76.5%) had died. Median survival time was 11 months, overall, and it was 36, 22, 9, 7, and 3 months for CLIP categories 0, 1, 2, 3, and 4 to 6, respectively. In multivariate analysis, the CLIP score had additional explanatory power above that of the Okuda stage. This was true for both patients treated with locoregional therapy or not. A quantitative estimation of 2-year survival predictive power showed that the CLIP score explained 37% of survival variability, compared with 21% explained by Okuda stage. In conclusion, the CLIP score, compared with the Okuda staging system, gives more accurate prognostic information, is statistically more efficient, and has a greater survival predictive power. It could be useful in treatment planning by improving baseline prognostic evaluation of patients with HCC, and could be used in prospective therapeutic trials as a stratification variable, reducing the variability of results owing to patient selection.

    Therapies for primary liver cancer, the third leading cause of cancer-related death worldwide, remain limited. Following multi-omics analysis (including whole genome and transcriptome sequencing), we were able to identify the dual-specific protein kinase TTK as a putative new prognostic biomarker for liver cancer. Herein, we show that levels of TTK protein are significantly elevated in neoplastic tissues from a cohort of liver cancer patients, when compared with adjacent hepatic tissues. We also tested the utility of TTK targeted inhibition and have demonstrated therapeutic potential in an experimental model of liver cancer in vivo. Following lentiviral shRNA knockdown in several human liver cancer cell lines, we demonstrated that TTK boosts cell growth and promotes cell spreading; as well as protects against senescence and decreases autophagy. In an experimental animal model, we show that in vitro knockdown of TTK effectively blocks intrahepatic growth of human HCC xenografts. Furthermore, we note that, in vivo silencing of TTK, by systemically delivering TTK siRNAs to already tumor-bearing liver, limits intrahepatic spread of liver cancer cells. This intervention is associated with decreased tumor aggressiveness, as well as increased senescence and autophagy. Taken together, our data suggest that targeted TTK inhibition might have clinical utility as an adjunct therapy in management of liver cancer. PMID:27618777

Following lentiviral shRNA knockdown in several human liver cancer cell lines, we demonstrated that TTK boosts cell growth and promotes cell spreading; as well as protects against senescence and decreases autophagy. In an experimental animal model, we show that in vitro knockdown of TTK effectively blocks intrahepatic growth of human HCC xenografts. Furthermore, we note that, in vivo silencing of TTK, by systemically delivering TTK siRNAs to already tumor-bearing liver, limits intrahepatic spread of liver cancer cells. This intervention is associated with decreased tumor aggressiveness, as well as increased senescence and autophagy. Taken together, our data suggest that targeted TTK inhibition might have clinical utility as an adjunct therapy in management of liver cancer.

    Therapies for primary liver cancer, the third leading cause of cancer-related death worldwide, remain limited. Following multi-omics analysis (including whole genome and transcriptome sequencing), we were able to identify the dual-specific protein kinase TTK as a putative new prognostic biomarker for liver cancer. Herein, we show that levels of TTK protein are significantly elevated in neoplastic tissues from a cohort of liver cancer patients, when compared with adjacent hepatic tissues. We also tested the utility of TTK targeted inhibition and have demonstrated therapeutic potential in an experimental model of liver cancer in vivo.

    Arsenic has been well documented as the major risk factor for development of blackfoot disease (BFD), a unique peripheral vascular disease that was once endemic to the southwestern coast of Taiwan, where residents imbibed artesian well water containing high concentrations of arsenic for more than 50yr. Long-term arsenic exposure has also been reported to be associated with increased incidence of liver cancer in a dose-responsive manner. A tap-water supply system was implemented in the early 1960s in the BFD endemic areas. Artesian well water was no longer used for drinking and cooking after the mid-1970s. The objective of this study was to examine whether liver cancer mortality rates were altered after the consumption of high-arsenic artesian well water ceased and, if so, when the reduction occurred. Standardized mortality ratios (SMRs) for liver cancer were calculated for the BFD endemic area for the years 1971-2000. Cumulative-sum techniques were used to detect the occurrence of changes in the SMRs. The study results show that mortality from liver cancer in females declined starting 9yr after the cessation of consumption of high-arsenic artesian well water. However, data show fluctuations in male liver cancer mortality rates. Based on the reversibility criterion, the association between arsenic exposure and liver cancer mortality is likely to be causal for females but not in males.

    Physiotherapy of cancer patients is one of the most controversial issues in our country. Malignant diseases are firstly mentioned as a contraindication of physiotherapy. Until now, physiotherapy was not suggested (or only in limited accessibility) for those patients who had malignant disease in medical history. International medical practice was less restrictive in managing this topic. The development of imaging techniques put this question in a new light. On the basis of evidence, the majority of articles have reported beneficial effects of physiotherapy in cancer patients, and only few articles mentioned it as harmful. Of course, each patient requires an individual assessment, however, if we exclude the possibility of tumor recurrence and metastasis, most of physiotherapy procedures can be used safely. One of the aims of this review is to support the physicians' decisions when to prescribe treatments, in such a way, that more patients could receive physiotherapy. Orv.

    Metformin, one of the most commonly used drugs for patients with type 2 diabetes, recently has received much attention regarding its anti-cancer action. It is thought that the suppression of mTOR signaling is involved in metformin's anti-cancer action. Although liver cancer is one of the most responsive types of cancer for reduction of incidence by metformin, the molecular mechanism of the suppression of mTOR in liver remains unknown. In this study, we investigated the mechanism of the suppressing effect of metformin on mTOR signaling and cell proliferation using human liver cancer cells. Metformin suppressed phosphorylation of p70-S6 kinase, and ribosome protein S6, downstream targets of mTOR, and suppressed cell proliferation. We found that DEPTOR, an endogenous substrate of mTOR suppression, is involved in the suppressing effect of metformin on mTOR signaling and cell proliferation in human liver cancer cells. Metformin increases the protein levels of DEPTOR, intensifies binding to mTOR, and exerts a suppressing effect on mTOR signaling. This increasing effect of DEPTOR by metformin is regulated by the proteasome degradation system; the suppressing effect of metformin on mTOR signaling and cell proliferation is in a DEPTOR-dependent manner. Furthermore, metformin exerts a suppressing effect on proteasome activity, DEPTOR-related mTOR signaling, and cell proliferation in an AMPK-dependent manner. We conclude that DEPTOR-related mTOR suppression is involved in metformin's anti-cancer action in liver, and could be a novel target for anti-cancer therapy. - Highlights: • We elucidated a novel pathway of metformin's anti-cancer action in HCC cells. • DEPTOR is involved in the suppressing effect of metformin on mTOR signaling. • Metformin increases DEPTOR protein levels via suppression of proteasome activity. • DEPTOR-related mTOR suppression is involved in metformin's anti-cancer action.

    AIM: Protocadherin-8 (PCDH8) plays an important role in signaling pathways of cell adhesin, proliferation, and migration. It has been reported that PCDH8 is mutated or methylated in several human cancers. However, little is known about PCDH8 in liver cancer. The aim of this study was to investigate the protein expression and promoter methylation status of PCDH8 in liver cancer and evaluate the association between PCDH8 methylation and the clinicopathological features. METHODS: The methylation status of PCDH8 in 42 hepatocellular carcinoma (HCC), 8 Cholangiocarcinoma (CC) and 50 normal liver tissues were examined using methylation-specific PCR (MSP) and the protein expression of PCDH8 was detected by immunohistochemistry. The relationships between PCDH8 methylation and clinicopathological features as well as overall survival of patients were evaluated. RESULTS: The PCDH8 methylation was more frequent in liver cancer tissues than that in the normal liver tissues (88% vs. 32%, P < 0.001), and is significantly associated with loss of its protein expression (P = 0.004). Moreover, there is a significant correlation between PCDH8 methylation and the alpha-fetoprotein (AFP) level (P = 0.008). Kaplan-Meier survival analysis revealed that patients with PCDH8 methylation have shorter OS and PFS than those without PCDH8 methylation (P = 0.041 and P = 0.028, respectively). CONCLUSION: PCDH8 is often inactivated by promoter methylation in liver cancer. PCDH8 methylation can serve as a valuable diagnostic biomarker for early detection of liver cancer and might be useful to predict an unfavorable clinical feature. PMID:26918058

    At diagnosis of colorectal cancer, approximately 25% of the patients have established colorectal liver metastasis. Optimal management of disseminated disease requires therapies targeting multiple stages in hepatic colorectal cancer metastasis development. To facilitate this, biologically accurate in vivo models are required. Early colonic cancer liver metastases development was studied using BDIX and Sprague-Dawley rat strains with human HT29 and rat DHDK12 colonic cancer cell lines. Different cancer cell-host combinations were used. Rat DHDK12 was previously chemically induced in the BDIX rat. Real-time intra-vital microscopy was employed to analyse the early development of liver metastases in four groups (n = 6 per group) (HT29-BDIX, DHDK12-BDIX, HT29-SD and DHDK12-SD). Data were compared using one-way anova with Bonferroni's multiple comparison test. The total number of tumour cells visualized, adherent cells within the hepatic sinusoids, extravasated tumour cells and migration rates were significantly higher in the DHDK12-BDIX combination. Maximum number of visualized cells and maximum migration rate were also significantly higher in this group. No significant differences were observed in these experimental parameters among the other three groups or in the haemodynamic parameters among all groups. In conclusion, cancer cell line-host selection has a significant effect on early colonic cancer liver metastasis development.

    During chemotherapy, drug resistance caused by autophagy remains a major challenge to successful treatment of cancer patients. The purpose of this study is to show that ulinastatin (UTI), a trypsin inhibitor, could reduce the resistance of liver cancer cells to chemotherapeutic agent epirubicin (EPI). We achieved this conclusion by analyzing the effect of EPI alone or UTI plus EPI on SMMC-7721 and MHCC-LM3 liver cancer cells. We also generated an EPI-resistant liver cancer cell line (MHCC-LM3er cells), and found that UTI could sensitize the LM3er cells to EPI. Autophagy usually functions to protect cancer cells during chemotherapy. Our study showed that UTI inhibited the autophagy induced by EPI in liver cancer cells, which promoted apoptosis, and therefore, reduced the resistance of the cancer cells to EPI. Further studies showed that the UTI-mediated inhibition on autophagy was achieved by inhibiting transcriptional factor nuclear factor-κB (NF-κB) signaling pathway. To verify our results in vivo, we injected MHCC-LM3 liver cancer cells or EPI-resistant LM3er cells into mice, and found that EPI could only effectively inhibit the growth of tumor in MHCC-LM3 cell-injected mice, but not in LM3er cell-injected mice. However, when UTI was also administered, the growth of tumor was inhibited in the MHCC-LM3er cell-injected mice as well. Our results suggest that UTI may be used in combination with anti-cancer drugs, such as EPI, to improve the outcome of cancer therapy.

    Purpose: To evaluate the residual error in liver position using breath-hold kilovoltage (kV) cone-beam computed tomography (CT) following on-line orthogonal megavoltage (MV) image-guided breath-hold liver cancer conformal radiotherapy. Methods and Materials: Thirteen patients with liver cancer treated with 6-fraction breath-hold conformal radiotherapy were investigated. Before each fraction, orthogonal MV images were obtained during exhale breath-hold, with repositioning for offsets >3 mm, using the diaphragm for cranio-caudal (CC) alignment and vertebral bodies for medial-lateral (ML) and anterior posterior (AP) alignment. After repositioning, repeat orthogonal MV images, orthogonal kV fluoroscopic movies, and kV cone-beam CTs were obtained in exhale breath-hold. The cone-beam CT livers were registered to the planning CT liver to obtain the residual setup error in liver position. Results: After repositioning, 78 orthogonal MV image pairs, 61 orthogonal kV image pairs, and 72 kV cone-beam CT scans were obtained. Population random setup errors ({sigma}) in liver position were 2.7 mm (CC), 2.3 mm (ML), and 3.0 mm (AP), and systematic errors ({sigma}) were 1.1 mm, 1.9 mm, and 1.3 mm in the superior, medial, and posterior directions. Liver offsets >5 mm were observed in 33% of cases; offsets >10 mm and liver deformation >5 mm were observed in a minority of patients. Conclusions: Liver position after radiation therapy guided with MV orthogonal imaging was within 5 mm of planned position in the majority of patients. kV cone-beam CT image guidance should improve accuracy with reduced dose compared with orthogonal MV image guidance for liver cancer radiation therapy.

    Timing and sequence of therapeutic interventions in patients with colorectal cancer (CRC) and synchronous liver metastases is a matter of ongoing discussion. The aim of this report is to show the feasibility and safety of a reversed strategy in patients with up front resectable synchronous liver metastases. Consecutive series of 15 patients with locally advanced rectal carcinoma and liver synchronous metastases where up front liver resection was carried out as an initial intervention is presented. Local treatment of both, metastatic disease and primary tumor, was preferred. Liver resection was followed by neoadjuvant (preoperative) concomitant radiochemotherapy (RCT) for local pelvic disease control and subsequent resection of rectum. Systemic adjuvant chemotherapy was placed at the end of the entire treatment cycle. All 15 patients after up front hepatectomy were able to proceed with their treatment plan. 14 patients completed their RCT for primary tumor and subsequent rectal resection was successfully carried out. In 12 of them. 3 patients showed complete clinical response on cross sectional imaging and a careful "wait-and-see" policy was adopted for them. In two patients metastatic disease progression was noticed during the treatment cycle.Liver first approach in patients with up front resectable colorectal liver metastases (CRLM) is safe and feasible. Local neoadjuvant treatment after CRLM resection may result in preoperative downsizing or even complete clinical response of the primary tumor. Reversed strategy may to a degree eliminate negative oncologic impact of surgical complications after rectal surgery as CRLM has been already addressed.

  6. Renal function in pediatric liver transplant patients.

    Actuarial five-year patient survivals after pediatric orthotopic liver transplantation (OLT) of 75 to 80% are now commonplace. However, renal dysfunction after pediatric OLT remains a serious complication and maybe broadly divided into four categories. The first is pre-existing renal disease in association with liver disease. This includes tyrosinemia with Fanconi syndrome, congenital cystic disease of the liver with associated polycystic disease of the kidney, Alagille's syndrome and primary hyperoxaluria. Second is hepatorenal syndrome. Resolution is dependent on successful OLT, although short-term dialysis may be required. Children with renal failure prior to transplantation have a significantly increased mortality. Third is peri- and early post-transplant renal impairment. The four major influences on early renal function after OLT are: (i) pretransplant renal function; (ii) early liver graft function; (iii) induction therapy with cyclosporine and tacrolimus; (iv) use of other nephrotoxic drugs. Fourth is long-term nephrotoxicity of cyclosporine and tacrolimus (FK-506). Both of these essential immunosuppressives carry the risk of long-term irreversible toxicity. In one study children, treated with cyclosporine, surviving > one year after OLT, 73% had a true GFR < 77 ml/min/1.73 m2. Children treated for > or = 24 months had a significantly lower GFR than those treated from 12 to 24 months. Half the children with a GFR < or = 50 ml/min/1.73 m2 had hypertension. Another study showed that 46% of pediatric OLT patients had a > or = 20% decrease in GFR over two to four years. FK-506 nephrotoxicity is comparable to that of cyclosporine. In a randomized control trial comparing FK-506 and cyclosporine, there was a 52% decrease in GFR over the first year in the FK-506 group, which was not significantly different to that of the cyclosporine group. In 60% of patients converted from cyclosporine to FK-506 one study showed a 50% or more drop in GFR. Both FK-506 and

    AIM: To increase inspiratory muscle strength and improve the quality of life of candidates for liver transplantation. METHODS: Twenty-three candidates for liver transplantation participated in the control group and 14 made up the intervention group. The control group consisted of 18 men and 5 women, body mass index (BMI) 27.3 ± 4.5 kg/m2 and Model for End-Stage Liver Disease (MELD) 18.2 ± 6.1. The intervention group consisted of 11 men and 3 women, BMI 28.6 ± 5.4 kg/m2 and MELD 18 ± 4.5. The presence or absence of ascites was identified in the first patient evaluation and after three months. We evaluated maximal inspiratory pressure (MIP) and maximal expiratory pressure, spirometry, root mean square (RMS) of diaphragm and rectus abdominis, and the quality of life. The exercises were performed daily by patients at home for three months and were supervised at distance monthly. The manual consisted of diaphragmatic breathing exercises, diaphragmatic isometric exercise, Threshold IMT®, lifting upper limbs with a bat and strengthening the abdomen. RESULTS: There was significant difference (P = 0.01) between the first (initial) and the third month (final) MIP in the control group and in the intervention group, but there was no difference (P = 0.45) between the groups. The RMS of the diaphragm was lower (P = 0.001) and the functional capacity was higher (P = 0.006) in the intervention group compared to the control. The general health and mental health domains received higher scores after three months in the control group (P = 0.01) and the intervention group (P = 0.004), but there was no significant difference between them. The comparison between the presence of initial ascites with the presence of ascites was performed after three months in the control group (P = 0.083) and intervention group (P = 0.31). There was no significant difference, in relation to the presence of ascites after three months between groups (P = 0.21). In the intervention group, patients with

    Pancreatic ductal adenocarcinoma (PDAC) is a devastating metastatic disease for which better therapies are urgently needed. Macrophages enhance metastasis in many cancer types, however, the role of macrophages in PDAC liver metastasis remains poorly understood. Here we found that PDAC liver metastasis critically depends on the early recruitment of granulin secreting inflammatory monocytes to the liver. Mechanistically, we demonstrate that granulin secretion by metastasis associated macrophages (MAMs) activates resident hepatic stellate cells (hStCs) into myofibroblasts that secrete periostin, resulting in a fibrotic microenvironment that sustains metastatic tumour growth. Disruption of MAM recruitment or genetic depletion of granulin reduced hStCs activation and liver metastasis. Interestingly, we found that circulating monocytes and hepatic MAMs in PDAC patients express high levels of granulin. These findings suggest that recruitment of granulin expressing inflammatory monocytes plays a key role in PDAC metastasis and may serve as a potential therapeutic target for PDAC liver metastasis.

    The author suspected that the high incidence of early recurrence after macroscopically curative operation in human liver cancers correlated with the production of liver regeneration factor which was induced following partial hepatectomy (PH). The author therefore analyzed whether PH enhanced the growth of liver cancers or not, and the relevant mechanism involved, using rats subcutaneously injected with hepatocellular carcinoma (KDH-8, AH-66) cells. Primarily, it proved that PH significantly enhanced the growth of liver cancers injected in rats. The effect of this enhancement of liver cancer growth appeared as an abrupt increase in tumor volume within 24 hours following PH, which fact was supported by the mitotic indices of the hepatocellular carcinoma (KDH-8) cells. However PH did not affect rats injected with mammary carcinoma (SST-2) cells without estrogen receptor (E2R) or fibrosarcoma (KMT-75) cells. Secondly, based on this result, the author tried to analyze the mechanism of enhanced growth of liver cancers following PH, from the standpoints of; changes in postoperative immunity, expression of cytosol E2R in liver cancer cells or liver regeneration factor, using KDH-8 cells. The changes in postoperative immunity (NK-activity and Blastogenesis) did not correlate with the changes in liver cancer growth. Although serum estradiol (E2) increased significantly after PH, E2R was not detected in the KDH-8 cells used in this experiment. Serum was obtained from healthy rats 24 hours after PH, and 20 mg of serum, as calculated from total protein, was eluted into 50 fractions by high liquid chromatography (column; TSK G3000 SW). When the author examined which fractions stimulated both the growth of primarily cultivated hepatocytes and KDH-8 cells, only the fraction Fr. 30, the molecular weight of which was about 100 Kd, enhanced both. Furthermore, the author performed an in vivo assay to determine the number of days needed for tumor appearance: PHs were carried out 2

  10. Deformable Dose Reconstruction to Optimize the Planning and Delivery of Liver Cancer Radiotherapy

    NASA Astrophysics Data System (ADS)

    Velec, Michael

    The precise delivery of radiation to liver cancer patients results in improved control with higher tumor doses and minimized normal tissues doses. A margin of normal tissue around the tumor requires irradiation however to account for treatment delivery uncertainties. Daily image-guidance allows targeting of the liver, a surrogate for the tumor, to reduce geometric errors. However poor direct tumor visualization, anatomical deformation and breathing motion introduce uncertainties between the planned dose, calculated on a single pre-treatment computed tomography image, and the dose that is delivered. A novel deformable image registration algorithm based on tissue biomechanics was applied to previous liver cancer patients to track targets and surrounding organs during radiotherapy. Modeling these daily anatomic variations permitted dose accumulation, thereby improving calculations of the delivered doses. The accuracy of the algorithm to track dose was validated using imaging from a deformable, 3-dimensional dosimeter able to optically track absorbed dose. Reconstructing the delivered dose revealed that 70% of patients had substantial deviations from the initial planned dose. An alternative image-guidance technique using respiratory-correlated imaging was simulated, which reduced both the residual tumor targeting errors and the magnitude of the delivered dose deviations. A planning and delivery strategy for liver radiotherapy was then developed that minimizes the impact of breathing motion, and applied a margin to account for the impact of liver deformation during treatment. This margin is 38% smaller on average than the margin used clinically, and permitted an average dose-escalation to liver tumors of 9% for the same risk of toxicity. Simulating the delivered dose with deformable dose reconstruction demonstrated the plans with smaller margins were robust as 90% of patients' tumors received the intended dose. This strategy can be readily implemented with widely

    We described a clinicopathological study of primary hepatoma associated with alcoholic liver diseases without viral liver diseases. In 150 patients with primary hepatoma, 6 patients (4%) have hepatoma associated with pure alcoholic liver disease, although 143 hepatoma were associated with chronic viral liver diseases and one was with primary biliary cirrhosis. All patients were male. The diagnosis of hepatoma was obtained at the age of 54 to 67 years old, and the duration of ethanol intake was 33 to 40 years. Three cases had a history of temperance. As an underlying liver disease, liver fibrosis was found in 3 cases and liver cirrhosis was in 3 cases. Chronic infections of hepatitis B and C viruses were ruled out by assaying serum virus markers. Autoimmune hepatitis and primary biliary cirrhosis were neglected by serum autoantibody. Hemochromatosis and Wilson's disease were also excluded. Hepatocellular carcinoma was diagnosed histologically in all the cases. Serum alpha-fetoprotein and PIVKA-II were positive in patients with advanced hepatocellular carcinoma. In cases with small hepatoma, the tumor was resected surgically in two cases and percutaneous ethanol injection against hepatoma was performed in one case. In these cases with small hepatoma, the patients were alive without tumor recurrence during observation period. In advanced hepatoma, transcatheter arterial infusion of anticancer agent was performed in two cases and no therapy was performed due to poor general condition in one case. One case was alive with recurrent hepatoma for 27 months, during which a therapy was repeated five times. Other 2 cases were died. The clinicopathological features of hepatoma associated with alcoholic liver disease were essentially same as those associated with chronic viral infection, although the incidence of hepatoma in alcoholic liver disease was lower than in viral liver disease. The mechanism of hepatocarcinogenesis in alcoholic liver disease was unclear and, therefore

    AIM: To expand the living donor liver transplantation (LT) pool of eligible patients with hepatocellular carcinoma (HCC) using new morphological and biological criteria. METHODS: Patients with HCC who underwent living donor LT (LDLT) from March 2005 to May 2013 at the National Cancer Center Korea (NCCK) were enrolled. We performed the 18F-fluorodeoxyglucose positron emission tomography/computed tomography (PET/CT) before LDLT. Overall and disease-free survival analysis was done in patients to evaluate the usefulness of new NCCK criteria using PET/CT and total tumor size (10 cm). RESULTS: We enrolled a total of 280 patients who pathologically confirmed to have HCC and performed the PET/CT before transplantation. Among them, 164 (58.6%) patients fulfilled the NCCK criteria and 132 patients (47.1%) met the Milan criteria. Five-year overall and disease-free survival rates for patients who fulfilled the NCCK criteria showed 85.2% and 84.0%, respectively, and were significantly higher than those beyond the NCCK criteria (60.2% and 44.4%, respectively; P < 0.001). The correlation analysis between preoperative imaging tests and pathologic reports using Cohen’s Kappa demonstrated the better results in the NCCK criteria than those in the Milan criteria (0.850 vs 0.583). The comparison of disease-free analysis among the NCCK, Milan, and University of California, San Francisco (UCSF) criteria using the receiver operating characteristics curves revealed the similar area under the curve value criteria (NCCK vs Milan, P = 0.484; NCCK vs UCSF, P = 0.189 at 5-years). CONCLUSION: The NCCK criteria using hybrid concept of both morphological and biological parameters showed an excellent agreement between preoperative imaging and pathological results, and favorable survival outcomes. These new criteria might select the optimal patients with HCC waiting LDLT and expand the selection pool. PMID:27358787

    AIM: To study local therapeutic efficacy, side effects, and complications of radiofrequency ablation (RFA), which is emerging as a new method for the treatment of patients with hepatocellular carcinoma (HCC) with cirrhosis or chronic hepatitis and metastatic liver cancer. METHODS: Thirty-six patients with primary and secondary liver cancers (21 with primary hepatocellular carcinoma, 12 with colorectal cancer liver metastases and 3 with other malignant liver metastases), which were considered not suitable for curative resection, were include in this study. They were treated either with RFA (RITA2000, Mountain View, California, USA) percutaneously (n = 20) or intraoperatively (n = 16). The procedures were performed using the ultrasound guidance. The quality of RFA were based on monitoring of equipments and subject feeling of the practitioners. Patients treated with RFA was followed according to clinical findings, radiographic images, and tumor markers. RESULTS: Thirty-six patients underwent RFA for 48 nodules. RFA was used to treat an average 1.3 lesions per patient, and the median size of treated lesions was 2.5 cm (range, 0.5-9 cm). The average hospital stay was 5.6 d overall (2.8 d for percutaneous cases and 7.9 d for open operations). Seven patients underwent a second RFA procedure (sequential ablations). Sixteen HCC patients with a high level of alpha fetoprotein (AFP) and 9 colorectal cancer liver metastases patients with a high level of serum carcinoembryonic antigen (CEA) have a great reduction benefited from RFA. Four (11.1%) patients had complications: one skin burn; one postoperative hemorrhage; one cholecystitis and one hepatic abscess associated with percutaneous ablations of a large lesion. There were 4 deaths: 3 patients died from local and system diseases (1 at 7 month, 1 at 9 month, and 1 at 12 month), 1 patients died from cardiovascular shock, but no RFA-related death. At a median follow-up of 10 mo (range, 1-24 mo), 6 patients (16.7%) had

    The worldwide shortage of donor livers to transplant end stage liver disease patients has prompted the search for alternative cell therapies for intractable liver diseases, such as acute liver failure, cirrhosis and hepatocellular carcinoma (HCC). Under normal circumstances the liver undergoes a low rate of hepatocyte 'wear and tear' renewal, but can mount a brisk regenerative response to the acute loss of two-thirds or more of the parenchymal mass. A body of evidence favours placement of a stem cell niche in the periportal regions, although the identity of such stem cells in rodents and man is far from clear. In animal models of liver disease, adopting strategies to provide a selective advantage for transplanted hepatocytes has proved highly effective in repopulating recipient livers, but the poor success of today's hepatocyte transplants can be attributed to the lack of a clinically applicable procedure to force a similar repopulation of the human liver. The activation of bipotential hepatic progenitor cells (HPCs) is clearly vital for survival in many cases of acute liver failure, and the signals that promote such reactions are being elucidated. Bone marrow cells (BMCs) make, at best, a trivial contribution to hepatocyte replacement after damage, but other BMCs contribute to the hepatic collagen-producing cell population, resulting in fibrotic disease; paradoxically, BMC transplantation may help alleviate established fibrotic disease. HCC may have its origins in either hepatocytes or HPCs, and HCCs, like other solid tumours appear to be sustained by a minority population of cancer stem cells. PMID:18991329

    Tumor-targeted delivery of anti-cancer drugs with controlled drug release function has been recognized as a promising strategy for pursuit of increased chemotherapeutic efficacy and reduced adverse effects. Development of magnetic nanoparticulates as delivery carriers to accommodate cytotoxic drugs for liver cancer treatment has evoked immense interest with respect to their convenience in biomedical application. Herein, we engineered multifunctional Janus nanocomposites, characterized by a head of magnetic Fe3O4 and a body of mesoporous SiO2 containing doxorubicin (DOX) as "nano-bullets" (M-MSNs-DOX). This nanodrug formulation possessed nanosize with controlled aspect-ratio, defined abundance in pore structures, and superior magnetic properties. M-MSN-DOX was determined to induce selective growth inhibition to the cancer cell under magnetic field rather than human normal cells due to its preferable endocytosis by the tumor cells and pH-promoted DOX release in the interior of cancer cells. Ultimately, both subcutaneous and orthotropic liver tumor models in mice have demonstrated that the proposed Janus nano-bullets imposed remarkable suppression of the tumor growth and significantly reduced systematic toxicity. Taken together, this study demonstrates an intriguing targeting strategy for liver cancer treatment based on a novel Janus nano-bullet, aiming for utilization of nanotechnology to obtain safe and efficient treatment of liver cancer.

    A recent cohort mortality study of male, hourly wage employees of a large Michigan chemical production and research facility had found a greater than expected number of deaths coded to liver and biliary tract cancer. In response, an additional investigation was then undertaken of the 44 liver and biliary tract cancer deaths observed between 1940 and 1982. A random sample (N = 1,888) of subjects was selected from the total cohort (N = 21,437) to serve as referents. Company work history records were used to classify cases and referents by work area assignment and potential for exposure to 11 selected chemical agents which have been shown to produce cancer of the liver or biliary passages in experimental animals. Statistically significant associations in both positive and negative directions were found for several work areas within the facility. A suggestive association was found for vinyl chloride monomer, based on five cases with presumed exposure.

    Background Liver failure following liver surgery is caused by an insufficient functioning remnant cell mass. This can be due to insufficient liver volume and can be aggravated by additional cell death during or after surgery. The aim of this study was to elucidate the causes of hepatocellular injury in patients undergoing liver resection. Methods Markers of hepatocyte injury (AST, GSTα, and L-FABP) and inflammation (IL-6) were measured in plasma of patients undergoing liver resection with and without intermittent inflow occlusion. To study the separate involvement of the intestines and the liver in systemic L-FABP release, arteriovenous concentration differences for L-FABP were measured. Results During liver manipulation, liver injury markers increased significantly. Arterial plasma levels and transhepatic and transintestinal concentration gradients of L-FABP indicated that this increase was exclusively due to hepatic and not due to intestinal release. Intermittent hepatic inflow occlusion, anesthesia, and liver transection did not further enhance arterial L-FABP and GSTα levels. Hepatocyte injury was followed by an inflammatory response. Conclusions This study shows that liver manipulation is a leading cause of hepatocyte injury during liver surgery. A potential causal relation between liver manipulation and systemic inflammation remains to be established; but since the inflammatory response is apparently initiated early during major abdominal surgery, interventions aimed at reducing postoperative inflammation and related complications should be started early during surgery or beforehand.

    Variegate porphyria (VP) and acute intermittent porphyria (AIP), the two most common types of acute porphyrias (AHPs), result from a partial deficiency of protoporphyrinogen oxidase (PPOX) and hydroxymethylbilane synthase (HMBS), respectively. A rare but serious complication in the AHPs is hepatocellular carcinoma (HCC). However, the underlying pathomechanisms are yet unknown. We performed DNA sequence analysis in cancerous and non-cancerous liver tissue of a VP and an AIP patient, both with HCC. In samples of both cancerous and non-cancerous liver tissues from the patients, we identified the underlying PPOX and HMBS germline mutations, c.1082dupC and p.G111R, respectively. Additionally, we detected a second somatic mutation, only in the cancer tissue i.e., p.L416X in the PPOX gene of the VP patient and p.L220X in the HMBS gene of the AIP patient, both located in trans to the respective germline mutations. Both somatic mutations were not detected in 10 non-porphyria-associated HCCs. Our data demonstrate that in the hepatic cancer tissue of AHP patients, somatic second-hit mutations result in nearly complete inactivation of the enzymes catalyzing major steps in the heme biosynthetic pathway. Both PPOX and HMBS, which might act as tumor suppressors, play a crucial role in the development of HCC in these individuals.

    Objective: To find out if there are any relationship between three single nucleotide polymorphisms (SNPs) of phosphatase and tensin homolog (PTEN) gene (rs1234213, rs1234220, and rs2299939) and the susceptibility of liver cancer. Methods: Genotypes of the three SNPs in the PTEN gene were achieved utilizing polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) method. Comparison of genotypes and alleles distribution differences between the case and the control subjects was accomplished with χ2 test. The analysis of linkage disequilibrium (LD) and haplotypes of the three SNPs was performed using SHEsis software. We adopted odds ratios (ORs) with 95% confidence intervals (95% CIs) to show the relative risk of liver cancer. Results: TC genotype and C allele of rs1234220 polymorphism showed much more frequently in cases than in controls, reflecting that the TC genotype and the C allele may be linked to the increased risk of liver cancer (OR=2.225, 95% CI=1.178-4.204; OR=1.941, 95% CI=1.124-3.351). Rs2299939 polymorphism showed an opposite result that the GT genotype probably reduce the risk of liver cancer (OR=0.483, 95% CI=0.259-0.900). Statistical significance was not found in the distribution differences of the genotypes of rs1234213 between two groups. LD and haplotype analysis results of the three SNPs showed that the T-C-G haplotype frequency was much higher in cases than in healthy objects, which proved that the T-C-G haplotype might be a susceptibility haplotype for liver cancer (OR=3.750, 95% CI=1.396-10.077). Conclusions: PTEN gene polymorphisms might relate to liver cancer risk. PMID:26823866

    Patients with cirrhosis are at higher risk of developing hepatocellular carcinoma (HCC), the second most frequent cause of cancer-related deaths. Although HCC diagnosis based on conventional morphological characteristics serves as the ``gold standard'' in the clinic, there is a high demand for more convenient and effective diagnostic methods that employ new biophysical perspectives. Here, we show that the nanomechanical signature of liver tissue is directly correlated with the development of HCC. Using indentation-type atomic force microscopy (IT-AFM), we demonstrate that the lowest elasticity peak (LEP) in the Young's modulus distribution of surgically removed liver cancer tissues can serve as a mechanical fingerprint to evaluate the malignancy of liver cancer. Cirrhotic tissues shared the same LEP as normal tissues. However, a noticeable downward shift in the LEP was detected when the cirrhotic tissues progressed to a malignant state, making the tumor tissues more prone to microvascular invasion. Cell-level mechanistic studies revealed that the expression level of a Rho-family effector (mDia1) was consistent with the mechanical trend exhibited by the tissue. Our findings indicate that the mechanical profiles of liver cancer tissues directly varied with tumor progression, providing an additional platform for the future diagnosis of HCC.Patients with cirrhosis are at higher risk of developing hepatocellular carcinoma (HCC), the second most frequent cause of cancer-related deaths.

Examples are the artificial kidney and the heart-lung machine. Artificial livers are being developed for patients with severe liver failure whose lives can only be saved at the present time by a transplant with a donor liver. These artificial livers are based either on a device that removes toxic materials from the patient's blood with, for example, albumin dialysis, or make use of bio-reactors filled with functioning liver cells, the so-called bio-artificial liver. In theory, the bio-artificial liver has the greatest potential to increase life expectancy. The results of clinical studies are also very promising. They are not yet sufficient, however, to permit general clinical use.

    Acid sphingomyelinase (ASM) regulates the homeostasis of sphingolipids, including ceramides and sphingosine-1-phosphate (S1P). These sphingolipids regulate carcinogenesis and proliferation, survival, and apoptosis of cancer cells. However, the role of ASM in host defense against liver metastasis remains unclear. In this study, the involvement of ASM in liver metastasis of colon cancer was examined using Asm-/- and Asm+/+ mice that were inoculated with SL4 colon cancer cells to produce metastatic liver tumors. Asm-/- mice demonstrated enhanced tumor growth and reduced macrophage accumulation in the tumor, accompanied by decreased numbers of hepatic myofibroblasts (hMFs), which express tissue inhibitor of metalloproteinase 1 (TIMP1), around the tumor margin. Tumor growth was increased by macrophage depletion or by Timp1 deficiency, but was decreased by hepatocyte-specific ASM overexpression, which was associated with increased S1P production. S1P stimulated macrophage migration and TIMP1 expression in hMFs in vitro. These findings indicate that ASM in the liver inhibits tumor growth through cytotoxic macrophage accumulation and TIMP1 production by hMFs in response to S1P. Targeting ASM may represent a new therapeutic strategy for treating liver metastasis of colon cancer.

    Hepatocellular carcinoma (HCC) is the fifth most common cancer and the third most common cause of cancer-related death worldwide. There have been great improvements in the diagnosis and treatment of HCC in recent years, but the problems, including difficult diagnosis at early stage, quick progression, and poor prognosis remain unsolved. Surgical resection is the mainstay of the treatment for HCC. However, 70%-80% of HCC patients are diagnosed at an advanced stage when most are ineligible for potentially curative therapies such as surgical resection and liver transplantation. In recent years, non-surgical management for unrespectable HCC, such as percutaneous ethanol injection, percutaneous microwave coagulation therapy, percutaneous radiofrequency ablation, transcatheter arterial chemoembolization, radiotherapy, chemotherapy, biotherapy, and hormonal therapy have been developed. These therapeutic options, either alone or in combination, have been shown to control tumor growth, prolong survival time, and improve quality of life to some extent. This review covers the current status and progress of non-surgical management for HCC. PMID:25469032

    Cardiovascular disease is as common in individuals with chronic liver disease as in the general population. Moreover, recent data suggest that patients with nonalcoholic fatty liver disease (NAFLD) may have a cardiovascular risk greater than that conferred by the conventional risk factors. There is unequivocal evidence that cardiovascular disease is an important cause of morbidity and mortality in this patient population and thus requires consideration of aggressive therapy with lipid-lowering agents such as statins. Because all statins are hepatically cleared and can cause elevations in liver biochemistries, there is a concern that patients with underlying liver disease may be at increased risk for hepatotoxicity. However, recent data, along with an assessment of statin safety by the Liver Expert Panel, suggest that statins are generally well tolerated in patients with chronic liver disease such as NAFLD, primary biliary cirrhosis, and hepatitis C virus. These drugs also appear to be safe in patients with stable/compensated cirrhosis. However, decompensated cirrhosis and acute liver failure should be considered contraindications for lipid-lowering therapy as these patients are unlikely to benefit because of their generally grave prognosis. Although routine hepatic biochemical test monitoring is recommended, the cost-effectiveness of this approach has been questioned. The benefit of statins in patients with underlying liver disease who are otherwise important candidates for statin therapy far outweighs the risk of a very rare event of serious liver injury.

    Metastatic growth by colorectal cancer cells in the liver requires the ability of the cancer cells to interact with the new microenvironment. This interaction results in three histological growth patterns of liver metastases: desmoplastic, pushing, and replacement. In primary colorectal cancer several proteases, involved in the degradation of extracellular matrix components, are up-regulated. In liver metastases, their expression is growth pattern dependent. Tissue inhibitor of matrix metalloproteinase-1 (TIMP-1) is a strong prognostic marker in plasma from colorectal cancer patients, with significant higher levels in patients with metastatic disease. We therefore wanted to determine the expression pattern of TIMP-1 in primary colorectal cancers and their matching liver metastases. TIMP-1 mRNA was primarily seen in α-smooth-muscle actin (α-SMA)-positive cells. In all primary tumors and liver metastases with desmoplastic growth pattern, TIMP-1 mRNA was primarily found in α-SMA-positive myofibroblasts located at the invasive front. Some α-SMA-positive cells with TIMP-1 mRNA were located adjacent to CD34-positive endothelial cells, identifying them as pericytes. This indicates that TIMP-1 in primary tumors and liver metastases with desmoplastic growth pattern has dual functions; being an MMP-inhibitor at the cancer periphery and involved in tumor-induced angiogenesis in the pericytes. In the liver metastases with pushing or replacement growth patterns, TIMP-1 was primarily expressed by activated hepatic stellate cells at the metastasis/liver parenchyma interface. These cells were located adjacent to CD34-positive endothelial cells, suggesting a function in tumor-induced angiogenesis. We therefore conclude that TIMP-1 expression is growth pattern dependent in colorectal cancer liver metastases.

    Pain management in patients with liver cirrhosis is a real challenge and is often inadequate due to a lack of therapeutic efficacy or the high incidence of adverse effects. The focus of treatment differs depending on whether the pain is acute or chronic and involves understanding the causative pathophysiological mechanism. Analgesics should be started with the minimum effective dose and should be titrated slowly with avoidance of polypharmacy. Adverse effects must be monitored, especially sedation and constipation, which predispose the patient to the development of hepatic encephalopathy. The first-line drug is paracetamol, which is safe at doses of 2-3g/day. Non-steroidal anti-inflammatory agents are contraindicated because they can cause acute renal failure and/or gastrointestinal bleeding. Tramadol is a safe option for moderate-severe pain. The opioids with the best safety profile are fentanyl and hydromorphone, with methadone as an alternative. Topical treatment can reduce oral drug consumption. In neuropathic pain the first-line therapeutic option is gabapentin. The use of antidepressants such as amitriptyline can be considered in some patients. Interventional techniques are a valuable tool in moderate to severe pain, since they allow a reduction in drug therapy and consequently its adverse effects. Psychological treatment, physical therapy and rehabilitation should be considered as part of multimodality therapy in the management of chronic pain.

We herein, report a case of follicular thyroid cancer with hyperfunctioning metastasis in a 43-year-old woman who presented with thyrotoxicosis, a cold right thyroid nodule, and low I-131 uptake at the thyroid bed. An additional total body scan with I-131 revealed a large radioiodine avid osteolytic bone metastasis with soft tissue masses and liver metastasis. The patient received treatment with total thyroidectomy, methimazole, and I-131 at a cumulative dose of 600 mCi along with recombinant human thyroid-stimulating hormone before the first I-131 treatment and palliative radiation. The patient had normal liver function test and experienced a mild degree of bone marrow suppression after I-131. At the 2-year follow-up, the patient was still alive with the progression of bone metastases but was doing well with less severe thyrotoxicosis, good ambulation, and an Eastern Cooperative Oncology Group performance status of 2. Clinicians should be aware of the unusual concurrent presentation of thyrotoxicosis and thyroid cancer, a differential diagnosis in patients with thyrotoxicosis and low or normal radioiodine uptake over the neck and also potential pitfalls during radionuclide treatment.

The patient had normal liver function test and experienced a mild degree of bone marrow suppression after I-131. At the 2-year follow-up, the patient was still alive with the progression of bone metastases but was doing well with less severe thyrotoxicosis, good ambulation, and an Eastern Cooperative Oncology Group performance status of 2. Clinicians should be aware of the unusual concurrent presentation of thyrotoxicosis and thyroid cancer, a differential diagnosis in patients with thyrotoxicosis and low or normal radioiodine uptake over the neck and also potential pitfalls during radionuclide treatment.

    Liver cancer or hepatocellular carcinoma (HCC) is a serious malady with only 10% survival rate. HCC incidence and mortality both are highest in China. This disease is detected and diagnosed by ultra sound, CT or MRI scans which are quite expensive. Also the discrimination between cirrhosis and HCC are poor by this imaging technique. The conventional tissue biopsy is quite invasive and painful. In this context, in the new diagnostic procedure presented in this paper, all the three liver malfunctions, particularly liver cancer, could be detected and discriminated by the spectral feature of blood and urine with accuracy about 80%. All that we need are 5 ml of blood and 5 ml of urine. Hence this inexpensive non invasive, optical technique will have significant impact in screening, diagnosis and also prognosis of HCC in large segment of people in the populous Asian countries.

    2015-01-01

    Small heterodimer partner (SHP; NR0B2) is a unique orphan nuclear receptor (NR) that contains a putative ligand-binding domain but lacks a DNA-binding domain. SHP is a transcriptional corepressor affecting diverse metabolic processes including bile acid synthesis, cholesterol and lipid metabolism, glucose and energy homeostasis, and reproductive biology via interaction with multiple NRs and transcriptional factors (TFs). Hepatocellular carcinoma (HCC) is one of the most deadly human cancers worldwide with few therapeutic options and poor prognosis. Recently, it is becoming clear that SHP plays an antitumor role in the development of liver cancer. In this review, we summarize the most recent findings regarding the new SHP interaction partners, new structural insights into SHP’s gene repressing activity, and SHP protein posttranslational modifications by bile acids. We also discuss the pleiotropic role of SHP in regulating cell proliferation, apoptosis, DNA methylation, and inflammation that are related to antitumor role of SHP in HCC. Improving our understanding of SHP’s antitumor role in the development of liver cancer will provide new insights into developing novel treatments or prevention strategies. Future research will focus on developing more efficacious and specific synthetic SHP ligands for pharmaceutical applications in liver cancer and several metabolic diseases such as hypercholesterolemia, obesity, diabetes, and fatty liver disease.

    Background/Aim: To elucidate colorectal cancer (CRC) disease patterns, demographics, characteristics, stage at presentation, metastases, and survival rates of patients, particularly those with liver metastases, at our center as the first report from the Kingdom of Saudi Arabia. Patients and Methods: We performed a retrospective, single-center database study based on the histological diagnosis of CRC in patients seen at the King Khalid University Hospital between 2007 and 2011. Results: 427 cases of CRC with a mean age at diagnosis of 55.47 ± 12.85 years, out of which 96% were resected. Stage II was predominant at presentation, followed by both stage III and IV, with the remainder being stage I. One hundred patients had distant metastases, of which the liver was the only location in 54 patients. Mean survival was 3.0 years. Overall survival rates for CRC patients with liver metastases who underwent resection were 30% at 2 years and 17% at 5 years, and the mean survival rate was 1.4 years. Conclusions: Both the mean survival rate of our CRC patients with resectable liver metastases and the 5-year survival rate of these patients are lower than global averages. This discrepancy is likely due to late diagnoses rather than more aggressive disease. PMID:27748323

    Hepatic ischemia/reperfusion (I/R) injury is a common clinical challenge. Despite accumulating evidence regarding its mechanisms and potential therapeutic approaches, hepatic I/R is still a leading cause of organ dysfunction, morbidity, and resource utilization, especially in those patients with underlying parenchymal abnormalities. In the oncological setting, there are growing concerns regarding the deleterious impact of I/R injury on the risk of post-surgical tumor recurrence. This review aims at giving the last updates regarding the role of hepatic I/R and liver parenchymal quality injury in the setting of oncological liver surgery, using a "bench-to-bedside" approach. Relevant medical literature was identified by searching PubMed and hand scanning of the reference lists of articles considered for inclusion. Numerous preclinical models have depicted the impact of I/R injury and hepatic parenchymal quality (steatosis, age) on increased cancer growth in the injured liver. Putative pathophysiological mechanisms linking I/R injury and liver cancer recurrence include an increased implantation of circulating cancer cells in the ischemic liver and the upregulation of proliferation and angiogenic factors following the ischemic insult. Although limited, there is growing clinical evidence that I/R injury and liver quality are associated with the risk of post-surgical cancer recurrence. In conclusion, on top of its harmful early impact on organ function, I/R injury is linked to increased tumor growth. Therapeutic strategies tackling I/R injury could not only improve post-surgical organ function, but also allow a reduction in the risk of cancer recurrence.

    2015-11-01

    An international panel of multidisciplinary experts convened to develop recommendations for managing patients with colorectal cancer (CRC) and synchronous liver metastases (CRCLM). A modified Delphi method was used. CRCLM is defined as liver metastases detected at or before diagnosis of the primary CRC. Early and late metachronous metastases are defined as those detected ⩽12months and >12months after surgery, respectively. To provide information on potential curability, use of high-quality contrast-enhanced computed tomography (CT) before chemotherapy is recommended. Magnetic resonance imaging is increasingly being used preoperatively to aid detection of subcentimetric metastases, and alongside CT in difficult situations. To evaluate operability, radiology should provide information on: nodule size and number, segmental localization and relationship with major vessels, response after neoadjuvant chemotherapy, non-tumoral liver condition and anticipated remnant liver volume. Pathological evaluation should assess response to preoperative chemotherapy for both the primary tumour and metastases, and provide information on the tumour, margin size and micrometastases. Although the treatment strategy depends on the clinical scenario, the consensus was for chemotherapy before surgery in most cases. When the primary CRC is asymptomatic, liver surgery may be performed first (reverse approach). When CRCLM are unresectable, the goal of preoperative chemotherapy is to downsize tumours to allow resection. Hepatic resection should not be denied to patients with stable disease after optimal chemotherapy, provided an adequate liver remnant with inflow and outflow preservation remains. All patients with synchronous CRCLM should be evaluated by a hepatobiliary multidisciplinary team.

    End-stage liver disease (ESLD) is life-threatening and liver transplantation (LTx) is the definitive treatment with good outcomes. Given the essential role of hepatocytes in Cu homeostasis, the potential of the serum Cu isotopic composition for monitoring a patient’s condition post-LTx was evaluated. For this purpose, high-precision Cu isotopic analysis of blood serum of ESLD patients pre- and post-LTx was accomplished via multi-collector ICP-mass spectrometry (MC-ICP-MS). The Cu isotopic composition of the ESLD patients was fractionated in favour of the lighter isotope (by about −0.50‰). Post-LTx, a generalized normalization of the Cu isotopic composition was observed for the patients with normal liver function, while it remained light when this condition was not reached. A strong decrease in the δ65Cu value a longer term post-LTx seems to indicate the recurrence of liver failure or cancer. The observed trend in favour of the heavier Cu isotopic composition post-LTx seems to be related with the restored biosynthetic capacity of the liver, the restored hepatic metabolism and/or the restored biliary secretion pathways. Thus, Cu isotopic analysis could be a valuable tool for the follow-up of liver transplant patients and for establishing the potential recurrence of liver failure. PMID:27468898

  9. Circulating Tumor Cells in Breast Cancer Patients.

    2016-01-01

    Breast cancer is the most commonly diagnosed cancer among women, resulting in an estimated 40,000 deaths in 2014.1 Metastasis, a complex, multi-step process, remains the primary cause of death for these patients. Although the mechanisms involved in metastasis have not been fully elucidated, considerable evidence suggests that metastatic spread is mediated by rare cells within the heterogeneous primary tumor that acquire the ability to invade into the bloodstream. In the bloodstream, they can travel to distant sites, sometimes remaining undetected and in a quiescent state for an extended period of time before they establish distant metastases in the bone, lung, liver, or brain. These occult micrometastatic cells (circulating tumor cells, CTCs) are rare, yet their prognostic significance has been demonstrated in both metastatic and non-metastatic breast cancer patients. Because repeated tumor tissue collection is typically not feasible and peripheral blood draws are minimally invasive, serial CTC enumeration might provide "real-time liquid biopsy" snapshots that could be used to identify early-stage breast cancer patients with micrometastatic disease who are at risk for disease progression and monitor treatment response in patients with advanced disease. In addition, characterizing CTCs might aid in the development of novel, personalized therapies aimed at eliminating micrometastases. This review describes current CTC isolation, detection, and characterization strategies in operable breast cancer. PMID:27481009

    A 69-year-old woman was diagnosed with descending colon cancer with multiple liver metastases, and a left hemicolectomy was performed. The patient was treated with capecitabine/oxaliplatin (CapeOX) plus bevacizumab (Bmab). After 5 courses of chemotherapy, the number and size of liver metastases remarkably reduced, and after the 12th course, because of peripheral neuropathy, a "stop-and-go"fashion of administering oxaliplatin (L-OHP) was initiated. After 14 courses, the liver metastases had disappeared. After the 33rd course of L-OHP treatment, the patient started receiving capecitabine therapy. The patient is recurrence-free 3 years after surgery, 14 months after achieving a complete response (CR). We report a case of long-term CR after surgery for descending colon cancer with multiple liver metastases, followed by a "stop-and-go" method of administering L-OHP or CapeOX plus Bmab therapy.

    In an attempt to define the mechanism of weight loss in cancer patients, fat and carbohydrate oxidation rates were calculated in 93 patients. Seventy patients with colorectal or gastric cancer were compared with a control group of 23 patients with nonmalignant illness. Twenty-seven patients with cancer and 13 control patients had lost more than 10% of their pre-illness body weight. Fat and carbohydrate oxidation rates were derived from measurements of oxygen consumption, carbon dioxide production, and urinary nitrogen excretion. Patients with cancer had significantly higher fat oxidation rates (p less than 0.01) and significantly lower carbohydrate oxidation rates (p less than 0.05) when compared with controls. Weight-losing cancer patients had significantly higher fat oxidation rates when compared with weight-stable cancer patients (p less than 0.02), weight-stable controls (p less than 0.01), and weight-losing controls (p less than 0.02). Cancer patients with liver metastases (N = 14) had significantly higher fat oxidation rates (p less than 0.01) and significantly lower carbohydrate oxidation rates (p less than 0.01) compared with cancer patients who had localized disease. There were no significant differences among the groups with respect to resting energy expenditure when expressed as kilocalorie per kilogram lean body mass per day. The presence of cancer appears to be associated with abnormal fat and carbohydrate metabolism. The increased rate of fat oxidation seen in patients with cancer, especially those with weight loss or liver metastases, may be a significant factor in the development of cancer cachexia.

    Patients with cirrhosis are at higher risk of developing hepatocellular carcinoma (HCC), the second most frequent cause of cancer-related deaths. Although HCC diagnosis based on conventional morphological characteristics serves as the "gold standard" in the clinic, there is a high demand for more convenient and effective diagnostic methods that employ new biophysical perspectives. Here, we show that the nanomechanical signature of liver tissue is directly correlated with the development of HCC. Using indentation-type atomic force microscopy (IT-AFM), we demonstrate that the lowest elasticity peak (LEP) in the Young's modulus distribution of surgically removed liver cancer tissues can serve as a mechanical fingerprint to evaluate the malignancy of liver cancer. Cirrhotic tissues shared the same LEP as normal tissues. However, a noticeable downward shift in the LEP was detected when the cirrhotic tissues progressed to a malignant state, making the tumor tissues more prone to microvascular invasion. Cell-level mechanistic studies revealed that the expression level of a Rho-family effector (mDia1) was consistent with the mechanical trend exhibited by the tissue. Our findings indicate that the mechanical profiles of liver cancer tissues directly varied with tumor progression, providing an additional platform for the future diagnosis of HCC. PMID:26168746

    Deaths from colorectal cancer are often due to liver metastasis. Trefoil factor-3 (TFF3) is expressed by normal intestinal epithelial cells and its expression is maintained throughout the colon adenoma-carcinoma sequence. Our previous work demonstrated a correlation between TFF3 expression and metastatic potential in an animal model of colon cancer. The aim of this study was to determine whether TFF3 is expressed in human colon cancer liver metastasis (CCLM) and whether inhibiting TFF3 expression in colon cancer cells would alter their invasive potential in vitro. Human CCLMs were analyzed at the mRNA and protein level for TFF3 expression. Two highly metastatic rat colon cancer cell lines that either natively express TFF3 (LN cells) or were transfected with TFF3 (LPCRI-2 cells), were treated with two rat TFF3 siRNA constructs (si78 and si365), and analyzed in an in vitro invasion assay. At the mRNA and protein level, TFF3 was expressed in 17/17 (100%) CCLMs and 10/11 (91%) primary colon cancers, but not in normal liver tissue. By real time PCR, TFF3 expression was markedly inhibited by both siRNA constructs in LN and LPCRI-2 cells. The si365 and si78 constructs inhibited invasion by 44% and 53%, respectively, in LN cells, and by 74% and 50%, respectively, in LPCRI-2 cells. These results provide further evidence that TFF3 contributes to the malignant behavior of colon cancer cells. These observations may have relevance for designing new diagnostic and treatment approaches to colorectal cancer.

    Purpose An update on pharmacotherapy for achieving and maintaining abstinence and mitigating hepatic damage in patients with alcoholic liver disease (ALD) is presented. Summary Currently there are limited pharmacotherapy options for managing ALD, which encompasses a broad spectrum of disorders ranging from steatosis and alcoholic hepatitis to fibrosis, cirrhosis, and hepatocellular cancer. Individual variation in the severity, presentation, and complex pathologenesis of ALD defines barriers to effective treatment. Scoring of disease severity using validated assessment instruments should guide treatment approaches; abstinence and proper nutrition continue to be the cornerstones of management. A literature search (through December 31, 2013) identified no reports of randomized controlled trials using Food and Drug Administration (FDA)-approved medications for the treatment of alcohol dependence in ALD-spectrum disorders. Disulfiram, acamprosate, and naltrexone (oral and intramuscular), while approved by FDA for treatment of alcohol dependence, are not currently approved for use in patients with ALD. Baclofen (also not FDA-approved for use in ALD) is the only medication available in the United States with demonstrated safety and efficacy in reducing alcoholic behavior that has been formally tested in clinical trials in patients with ALD. Pharmacotherapy of alcoholic hepatitis using glucocorticoids or pentoxifylline has shown promise, but these options are reserved for severe ALD only. Conclusion Although various treatments have been investigated for ALD in patients with alcoholism, complete abstinence from alcohol is currently the only recommended form of hepatoprotection for the entire spectrum of ALD diagnoses.

    Little is known about the biological characteristics that determine the prognosis of colorectal cancer (CRC) liver metastases. In previous work we reported three different histological patterns of the tumour-liver interface of CRC liver metastases, termed the pushing, replacement and desmoplastic growth pattern (GP). The purpose of this study was to confirm differences in angiogenic and hypoxic properties of CRC liver metastases with different GPs in a large data set and to study the value of the GP as a prognostic factor. In 205 patients undergoing a resection of CRC liver metastases, the GP of the metastasis was determined using haematoxylin-eosin and Gordon Sweet's silver staining. The tumour cell proliferation fraction (TCP%), endothelial cell proliferation fraction (ECP%) and carbonic anhydrase 9 (CA9) expression were determined using immunohistochemistry. Standard clinicopathological data and overall survival were recorded. 27.8, 15.6, 34.6 and 17.6 % of liver metastases had a replacement, pushing, desmoplastic and mixed GP, respectively. Analyses of TCP%, ECP% and CA9 expression demonstrated that CRC liver metastases with a replacement GP are non-angiogenic, while the ones with a pushing GP are the most angiogenic with angiogenesis being, at least partially, hypoxia-driven. GP (pushing or not) was the only independent predictor of survival at 2 years. CRC liver metastases grow according to different GP patterns with different angiogenic properties. At 2 years of follow-up a GP with a pushing component was an independent predictor of poor survival, suggesting that the pushing GP is characterized by a more aggressive tumour biology. Further elucidation of the mechanisms and biological pathways involved in and responsible for the differences in GP between CRC liver metastases in different patients might lead to therapeutic agents and strategies taking advantage of this 2 year 'window of opportunity'.

    2014-01-01

    Background Colorectal cancer is the third most frequently diagnosed cancer and the third cause of cancer deaths in the United States. Despite the fact that tumor cell-intrinsic mechanisms controlling colorectal carcinogenesis have been identified, novel prognostic and diagnostic tools as well as novel therapeutic strategies are still needed to monitor and target colon cancer progression. We and others have previously shown, using mouse models, that the extracellular matrix (ECM), a major component of the tumor microenvironment, is an important contributor to tumor progression. In order to identify candidate biomarkers, we sought to define ECM signatures of metastatic colorectal cancers and their metastases to the liver. Methods We have used enrichment of extracellular matrix (ECM) from human patient samples and proteomics to define the ECM composition of primary colon carcinomas and their metastases to liver in comparison with normal colon and liver samples. Results We show that robust signatures of ECM proteins characteristic of each tissue, normal and malignant, can be defined using relatively small samples from small numbers of patients. Comparisons with gene expression data from larger cohorts of patients confirm the association of subsets of the proteins identified by proteomic analysis with tumor progression and metastasis. Conclusions The ECM protein signatures of metastatic primary colon carcinomas and metastases to liver defined in this study, offer promise for development of diagnostic and prognostic signatures of metastatic potential of colon tumors. The ECM proteins defined here represent candidate serological or tissue biomarkers and potential targets for imaging of occult metastases and residual or recurrent tumors and conceivably for therapies. Furthermore, the methods described here can be applied to other tumor types and can be used to investigate other questions such as the role of ECM in resistance to therapy. PMID:25037231

    Abstract This study aimed to assess the efficacy and safety of bevacizumab plus preoperative chemotherapy as first-line treatment for liver-only metastatic colorectal cancer in Chinese patients compared with those of preoperative chemotherapy alone. Patients with histologically confirmed liver-only metastatic colorectal cancer were sequentially reviewed, and received either preoperative chemotherapy plus bevacizumab (bevacizumab group, n = 32) or preoperative chemotherapy alone (chemotherapy group, n = 57). Progression-free survival, response rate, liver resection rate, conversion rate, and safety were analyzed. With median follow-up of 28.7 months, progression-free survival was 10.9 months (95% confidence interval: 8.7–13.1 months) in bevacizumab group and 9.9 months (95% confidence interval: 6.8–13.1 months) in chemotherapy group (P = 0.472). Response rates were 59.4% in bevacizumab group and 38.6% in chemotherapy group (P = 0.059). Overall liver resection (R0, R1, and R2) rate was 68.8% in bevacizumab group and 54.4% in chemotherapy group (P = 0.185). Conversion rate was 51.9% in bevacizumab group and 40.4% in chemotherapy group (P = 0.341). No postoperative complication was observed in all patients. Bevacizumab plus preoperative chemotherapy as first-line treatment for liver-only metastatic colorectal cancer tends to achieve better clinical benefit with controllable safety in Chinese patients.

    2016-01-01

    Hepatocellular carcinoma (HCC) is the main common primary tumour of the liver and it is usually associated with cirrhosis. The barcelona clinic liver cancer (BCLC) classification has been approved as guidance for HCC treatment algorithms by the European Association for the Study of Liver and the American Association for the Study of Liver Disease. According to this algorithm, hepatic resection should be performed only in patients with small single tumours of 2-3 cm without signs of portal hypertension (PHT) or hyperbilirubinemia. BCLC classification has been criticised and many studies have shown that multiple tumors and large tumors, as wide as those with macrovascular infiltration and PHT, could benefit from liver resection. Consequently, treatment guidelines should be revised and patients with intermediate/advanced stage HCC, when technically resectable, should receive the opportunity to be treated with radical surgical treatment. Nevertheless, the surgical treatment of HCC on cirrhosis is complex: The goal to be oncologically radical has always to be balanced with the necessity to minimize organ damage. The aim of this review was to analyze when and how liver resection could be indicated beyond BCLC indication. In particular, the role of multidisciplinary approach to assure a proper indication, of the intraoperative ultrasound for intra-operative restaging and resection guidance and of laparoscopy to minimize surgical trauma have been enhanced.

    Liver kinase B1 (LKB1) is a tumor suppressor, and its loss might lead to activation of the mammalian target of rapamycin (mTOR) and tumorigenesis. This study aimed to determine the clinical relevance of LKB1 gene and protein expression in breast cancer patients. LKB1 protein expression was evaluated using immunohistochemistry in tumors from early breast cancer patients in two Taiwanese medical centers. Data on LKB1 gene expression were obtained from the Molecular Taxonomy of Breast Cancer International Consortium (METABRIC) data set. The correlations between LKB1 expression, clinicopathologic factors, and patient outcome were analyzed. LKB1 expression was significantly associated with estrogen receptor (ER) expression in 2 of the 4 cohorts, but not with other clinicopathologic factors. LKB1 expression was not a predictor for relapse-free survival, overall survival (OS), or breast cancer-specific survival. In a subgroup analysis of the two Taiwanese cohorts, high LKB1 protein expression was predictive of high OS in human epidermal growth factor receptor 2 (HER2)-positive breast cancer patients (P = 0.013). Our study results indicate that LKB1 expression is not prognostic in the whole population of breast cancer patients, but it is a potential predictor of OS in the subset of HER2-positive patients PMID:26877155

    Context The liver, one of the most important organs of the body, is known to be responsible for several functions. The functional contribution of the liver to the metabolism of carbohydrates, protein, drugs and toxins, fats and cholesterol and many other biological processes are still unknown. Liver disorders are classified into two types: acute and chronic. Different drugs are used in liver diseases to treat and control pain. Most pain relief medications such as opioids are metabolized via the liver; therefore, the adverse reactions of drugs are probably higher for patients with liver disease. The current study aimed to evaluate the effects of opioid drugs on patients with liver disease; therefore, it is necessary to select suitable opioids for such patients. Evidence Acquisition This review was written by referring to research literature including 70 articles and four textbooks published from 1958 to 2015 on various reputable sites. Searches were carried out on the key phrases of narcotic pain relievers (opioids), acute and chronic hepatic failure, opioid adverse drug reactions, drug-induced liver injury (DILI) and other similar keywords. References included a variety of research papers (descriptive and analytical), intervention and review articles. Results In patients with liver disease, administration of opioid analgesics should be observed, accurately. As a general rule, lower doses of drugs should be administered at regular intervals based on the signs of drug accumulation. Secondly, the interactions of opioid drugs with different levels of substrates of the P450 cytochrome enzyme should be considered. Conclusions Pain management in patients with liver dysfunction is always challenging to physicians because of the adverse reactions of drugs, especially opioids. Opioids should be used cautiously since they can cause sedation, constipation and sudden encephalopathy effects. Since the clearance of these drugs in patients with hepatic insufficiency is decreased

    We used supersonic shear imaging to determine the liver stiffness (LS) values of 82 patients without known liver pathology and studied the factors that influence these measurements. Five LS measurements were made in each subject, and the median value, expressed in kilopascals, was calculated. Reliable LS measurements were obtained in 84.5% of patients. Higher body mass index and older age were associated with failure to obtain reliable measurements. The mean value of LS measurements determined by SSI in our cohort of patients without known liver pathology was 6 ± 1.4 kPa. The mean LS measurements determined by SSI for men were significantly higher than those for women; body mass index did not significantly influence SSI measurements. Thus, 6 kPa is the mean SSI value in patients without known liver pathology, with higher values being obtained in men.

    Hepatocellular carcinoma (HCC) is the most common primary malignant tumor of the liver, accounting for 80%–90% of all liver cancers. The disease ranks as the fifth most common cancer worldwide and is the third leading cause of all cancer-associated deaths. Although advances in HCC detection and treatment have increased the likelihood of a cure at early stages of the disease, HCC remains largely incurable because of late presentation and tumor recurrence. Only 25% of HCC patients are deemed suitable for curative treatment, with the overall survival at just a few months for inoperable patients. Apart from surgical resection, loco-regional ablation and liver transplantation, current treatment protocols include conventional cytotoxic chemotherapy. But due to the highly resistant nature of the disease, the efficacy of the latter regimen is limited. The recent emergence of the cancer stem cell (CSC) concept lends insight into the explanation of why treatment with chemotherapy often may seem to be initially successful but results in not only a failure to eradicate the tumor but also possibly tumor relapse. Commonly used anti-cancer drugs in HCC work by targeting the rapidly proliferating and differentiated liver cancer cells that constitute the bulk of the tumor. However, a subset of CSCs exists within the tumor, which are more resistant and are able to survive and maintain residence after treatment, thus, growing and self-renewing to generate the development and spread of recurrent tumors in HCC. In the past few years, compelling evidence has emerged in support of the hierarchic CSC model for solid tumors, including HCC. And in particular, CD133 has drawn significant attention as a critical liver CSC marker. Understanding the characteristics and function of CD133{sup +} liver CSCs has also shed light on HCC management and treatment, including the implications for prognosis, prediction and treatment resistance.

    Primary cancer of the liver (hepatocellular carcinoma, HCC) is one of the most common cancers worldwide; HBV is the major cause of HCC. A vaccine that protects against HBV infection was invented in 1969 and is now one of the most commonly used vaccines. National vaccination programs have dramatically reduced the prevalence of HBV infection and carriers, with a concomitant decrease in the incidence of HCC in the vaccine-impacted populations. HBV vaccine is the first widely used cancer prevention vaccine; a second that protects against papilloma virus and cancer of the cervix has recently been introduced. Appropriate treatment of HBV carriers with antivirals can reduce the titers of HBV in their blood and thereby greatly reduce the risk of HCC and chronic liver disease. Further data are required to establish criterion for treatment to enable protocols for medical and prevention programs. There are other viral caused cancers and an understanding of their pathogenesis is an important future direction for research to reduce the human burden of cancer. PMID:20036981

    To prevent probable occult metastatic liver cancer from progressing to clinical disease, the author used internal radiation therapy as an effective adjuvant to surgical excision of primary Dukes' C colonic cancer. A calculated radiation dose of 5000 rads was delivered to the liver by injecting radioactive 32-P chromic phosphate colloid through the superior mesenteric and celiac arteries. When this was done, the colloid passed through the intestines and was mixed thoroughly with the blood and delivered to the liver by the portal vein. The Kupffer cells in the liver trapped the colloid, and a minimum amount passed through the liver and got into the general circulation. This kept the amount of colloid deposited in the bone marrow to a minimum. In a phase-I pilot study in which nine patients were treated, no serious side effects were noted. In eight patients, the liver has remained free of cancer for more than 1 year.

    A retrospective review of all 248 liver biopsies performed in patients with HIV infection at two referral centres in London over a 12 year period revealed five cases of major bleeding following biopsy, with four deaths. The risk of major bleeding was 2.0%, and mortality was 1.6% following liver biopsy. The risk of bleeding as much higher than in published series of biopsies done in patients without HIV infection, owing in part to the high prevalence of thrombocytopaenia and clotting abnormalities in patients with HIV infection. HIV infection per se may also increase the risk of bleeding following liver biopsy. PMID:8655172

    Background: Type II diabetes increases liver cancer risk but the risk may be mitigated by anti-diabetic medications. However, choice of medications is correlated with diabetes duration and severity, leading to confounding by indication. Methods: To address this association, we conducted a nested case–control study among persons with type II diabetes in the Clinical Practice Research Datalink. Cases had primary liver cancer and controls were matched on age, sex, practice, calendar time, and number of years in the database. Exposure was classified by type and combination of anti-diabetic prescribed and compared to non-use. Odds ratios (ORs) and 95% confidence intervals (95% CI) were calculated using conditional logistic regression. Results: In 305 cases of liver cancer and 1151 controls, there was no association between liver cancer and anti-diabetic medication use compared to non-use (OR=0.74 (95% CI=0.45–1.20) for metformin-only, 1.10 (95% CI=0.66–1.84) for other oral hypoglycaemic (OH)-only, 0.89 (95% CI=0.58–1.37) for metformin+other OH, 1.11 (95% CI=0.60–2.05) for metformin+insulin, 0.81 (95% CI=0.23–2.85) for other OH+insulin, and 0.72 (95% CI=0.18–2.84) for insulin-only). Stratification by duration of diabetes did not alter the results. Conclusions: Use of any anti-diabetic medications in patients with type II diabetes was not associated with liver cancer, though there was a suggestion of a small protective effect for metformin.

    AIM: To explore recent trends, modes of diagnosis, ethnic distribution and the mortality to incidence ratio of primary liver cancer by subtypes in England and Wales. METHODS: We obtained incidence (1979-2008) and mortality (1968-2008) data for primary liver cancer for England and Wales and calculated age-standardised incidence and mortality rates. Trends in age-standardised mortality (ASMR) and incidence (ASIR) rates and basis of diagnosis of primary liver cancer and subcategories: hepatocellular carcinoma, intrahepatic bile duct and unspecified liver tumours, were analysed over the study period. Changes in guidelines for the diagnosis of primary liver cancer (PLC) may impact changing trends in the rates that may be obtained. We thus explored changes in the mode of diagnosis as reported to cancer registries. Furthermore, we examined the distribution of these tumours by ethnicity. Most of the statistical manipulations of these data was carried out in Microsoft excel® (Seattle, Washington, United Sttaes). Additional epidemiological statistics were done in Epi Info software (Atlanta, GA, United Sttaes). To define patterns of change over time, we evaluated trends in ASMR and ASIR of PLC and intrahepatic bile duct carcinoma (IHBD) using a least squares regression line fitted to the natural logarithm of the mortality and incidence rates. We estimated the patterns of survival over subsequent 5 and 10 years using complement of mortality to incidence ratio (1-MIR). RESULTS: Age-standardised mortality rate of primary liver cancer increased in both sexes: from 2.56 and 1.29/100000 in 1968 to 5.10 and 2.63/100000 in 2008 for men and women respectively. The use of histology for diagnostic confirmation of primary liver cancer increased from 35.7% of registered cases in 1993 to plateau at about 50% during 2005 to 2008. Reliance on cytology as a basis of diagnosis has maintained a downward trend throughout the study period. Although approximately 30% of the PLC registrations had

    Alcoholic liver disease (ALD) consists of a broad spectrum of disorders, ranging from simple steatosis to alcoholic steatohepatitis and cirrhosis. Fatty liver develops in more than 90% of heavy drinkers, however only 30%-35% of them develop more advanced forms of ALD. Therefore, even if the current "gold standard" for the assessment of the stage of alcohol-related liver injury is histology, liver biopsy is not reasonable in all patients who present with ALD. Currently, although several non-invasive fibrosis markers have been suggested as alternatives to liver biopsy in patients with ALD, none has been sufficiently validated. As described in other liver disease, the diagnostic accuracy of such tests in ALD is acceptable for the diagnosis of significant fibrosis or cirrhosis but not for lesser fibrosis stages. Existing data suggest that the use of non-invasive tests could be tailored to first tier screening of patients at risk, in order to diagnose early patients with progressive liver disease and offer targeted interventions for the prevention of decompensation. We review these tests and critically appraise the existing evidence.

    Background Health care spending is known to be highly skewed, with a small subset of the population consuming a disproportionate amount of health care resources. Patients with cancer are high-cost users because of high incremental health care costs for treatment and the growing prevalence of cancer. The objectives of the present study included characterizing cancer-patient trajectories by cost, and identifying the patient and health system characteristics associated with high health system costs after cancer treatment. Methods This retrospective cohort study identified Ontario adults newly diagnosed with cancer between 1 April 2009 and 30 September 2010. Costs of health care use before, during, and after cancer episodes were used to develop trajectories of care. Descriptive analyses examined differences between the trajectories in terms of clinical and health system characteristics, and a logistic regression approach identified predictors of being a high-cost user after a cancer episode. Results Ten trajectories were developed based on whether patients were high- or low-cost users before and after their cancer episode. The most common trajectory represented patients who were low-cost in the year before cancer, survived treatment, and continued to be low-cost in the year after cancer (31.4%); stage ii cancer of the male genital system was the most common diagnosis within that trajectory. Regression analyses identified increases in age and in multimorbidity and low continuity of care as the strongest predictors of high-cost status after cancer. Conclusions Findings highlight an opportunity to proactively identify patients who might transition to high-cost status after cancer treatment and to remediate that transition. PMID:26985150

    The acute renal failure is the frequent medical complication observed in liver transplant patients. The objective of this study was to determine the cause of acute renal failure in post liver transplant patients. A total of 70 patients who underwent (cadaveric 52, live 18) liver transplantation were categorized based on clinical presentation into two groups, namely hepatorenal failure (HRF, n = 29), and Hepatic failure (HF, n = 41). All the patients after the liver transplant had received tacrolimus, mycophenolate and steroids. We analyzed the modification of diet in renal disease, (MDRD) serum urea, creatinine and albumin before and after 5th and 30th day of liver transplant and data was categorized into survivors and non-survivors group. In HRF survivor group, serum creatinine, and urea levels were high and, albumin, MDRD were low in pre- transplant and reached to normal levels on 30th day of post transplant, and 79.3 % of patients in this group showed resumption of normal kidney function. On the contrary in HRF nonsurvivor group, we did not observed any significant difference and 20.7 % of patients showed irreversible changes after the liver transplant. In HF survivor group, 82.9 % of liver failure patients did not show any deviation in serum creatinine, urea, albumin and MDRD, whereas in HF non survivor group, 17.1 % of liver failure patients who had HCV positive before the transplant developed acute renal failure. The levels of creatinine, urea, albumin and MDRD were normal before the transplant and on day 30th, the levels of albumin and MDRD were significantly low whereas serum urea, creatinine levels were high. In conclusion, based on these observations, an diagnosis and treatment of Acute renal failure is important among the liver transplantation cases in the early postoperative period.

    AIM: To study the relationship between intercellular adhesive molecule-1 (ICAM-1) and liver cancer metastasis and to search for factors to predict metastasis of liver cancer. METHODS: ICAM-1 expression in fresh tissues of normal liver and hepatocellular cancer (HCC) was examined by immunoperoxidase staining. The expression of ICAM-1 in human hepatoma, tumor surrounding tissues and normal livers were semiquantitatively analyzed by Dot immuno blot. Tissue ICAM-1 expression at mRNA level was detected by Northern blot. RESULTS: All 6 cases of normal liver samples were negative in anti-ICAM-1 immunohistochemical staining, 80.0% (36/45) of HCC presented various ICAM-1 expression. The number of positive cells was a little higher in large tumors, tumors with intact capsule and metastasis, but there was no significant difference. Two cases with cancer embolus also had high ICAM-1 expression. ICAM-1 concentration in HCC (13.43 ± 0.09) was higher than that in tumor surrounding tissues (5.89 ± 0.17, P < 0.01) and normal livers (4.27 ± 0.21, P < 0.01). It was also higher in metastasis group (20.24 ± 0.30) than in nonmetastasis group (10.23 ± 0.12, P < 0.05). Northern blot analysis revealed that ICAM-1 expression at mRNA level was also higher in HCC and cancer embolus than that in tumor surrounding tissues and normal livers. CONCLUSION: Tissue ICAM-1 could indicate the growth and metastasis of HCC, and may be an index that can predict liver cancer metastasis. PMID:11819275

    Twenty-five adult patients with liver cirrhosis, and another 30 patients with no liver disease but referred with symptoms suggestive of gastroesophageal reflux disease were selected at random. Twenty-four hour ambulatory intra-esophageal pH measurement and upper gastrointestinal endoscopy were carried out on all patients recruited. Applying the former test, 16 (64%) of the patients with liver cirrhosis have gastroesophageal reflux disease. This figure is comparable with the 70% (21/30) rate recorded in the group of dyspeptic patients clinically thought to have the disorder. A positive endoscopic diagnosis was much lower at 12% and 23%, respectively. No significant differences were observed among liver disease patients when they were subdivided in accordance with the etiology of liver cirrhosis and the grade of esophageal varices. We conclude that gastroesophageal reflux disease occurs at a high frequency (64%) in patients with liver cirrhosis and portal hypertension, irrespective of the etiology of cirrhosis and the grade of esophageal varices. It is therefore considered to be the main cause of esophagitis in these patients, and that it might play a role in initiating a variceal bleeding episode. The latter hypothesis needs further evaluation. PMID:8270239

    Several clinical studies have suggested that excess hepatic iron accumulation is a progressive factor in some liver diseases including chronic viral hepatitis and hemochromatosis. However, it is not known whether iron-induced hepatotoxicity may be directly involved in hepatitis, cirrhosis, and liver cancer. The Long-Evans Cinnamon (LEC) rat, which accumulates excess copper in the liver as in patients with Wilson's disease, is of a mutant strain displaying spontaneous hemolysis, hepatitis, and liver cancer. We found previously that LEC rats harbored an additional abnormality: accumulation of as much iron as copper in the liver. In the present study, we compared the occurrence of hepatitis and liver cancer in LEC rats fed an iron-deficient diet (ID) with those in rats fed a regular diet (RD). The RD group showed rapid increments of hepatic iron concentrations as the result of hemolysis, characteristics of fulminant hepatitis showing apoptosis, and a 53% mortality rate. However, no rats in the ID group died of fulminant hepatitis. Hepatic iron, especially "free" iron concentration and the extent of hepatic fibrosis in the ID group were far less than those of the RD group. At week 65, all rats in the RD group developed liver cancer, whereas none did in the ID group. These results suggest that the accumulation of iron, possibly by virtue of synergistic radical formation with copper, plays an essential role in the development of fulminant hepatitis, hepatic fibrosis, and subsequent hepatocarcinogenesis in LEC rats.

    Cancer stem cells (CSCs), also known as tumor-initiating cells, are highly metastatic, chemo-resistant and tumorigenic, and are critical for cancer development, maintenance and recurrence. Oncolytic adenovirus could targetedly kill CSCs and has been acted as a promising anticancer agent. Currently, a novel GP73-regulated oncolytic adenovirus GD55 was constructed to specifically treat liver cancer and exhibited obvious cytotoxicity effect. However, there remains to be confirmed that whether GD55 could effectively eliminate liver CSCs. We first utilized the suspension culture to enrich the liver CSCs-like cells, which acquires the properties of liver CSCs in self-renewal, differentiation, quiescence, chemo-resistance and tumorigenicity. The results indicated that GD55 elicited more significant cytotoxicity and stronger oncolytic effect in liver CSC-like cells compared to common oncolytic virus ZD55. Additionally, GD55 possessed the greater efficacy in suppressing the growth of implanted tumors derived from liver CSC-like cells than ZD55. Furthermore, GD55 induced remarkable apoptosis of liver CSC-like cells in vitro and in vivo, and inhibited the propogation of cells and angiogenesis in xenograft tumor tissues. Thus, GD55 may virtually represent an attractive therapeutic agent for targeting liver CSCs to achieve better clinical outcomes for HCC patients. PMID:27121064

    Oxaliplatin is an effective chemotherapeutic agent for the treatment of colorectal cancer; however, it may cause liver injury, particularly sinusoidal obstruction syndrome (SOS). Although SOS does not usually present with focal lesions on radiological images, the present study describes the case of a 22-year-old woman with oxaliplatin-induced SOS mimicking metastatic colon cancer in the liver. An abdominal computed tomography revealed a novel 1 cm, low-density lesion in segment 1 of the liver following the administration of the fourth round of oxaliplatin-based adjuvant chemotherapy for stage III colon cancer. Since the lesion was indistinguishable from metastasis, even with detailed imaging studies, including magnetic resonance imaging and positron emission tomography-computed tomography, an isolated caudate lobectomy was planned. The cut surface of the resected liver showed a localized reddish congested lesion measuring 1.4 cm in diameter. The adjacent hepatic parenchyma also demonstrated diffuse sinusoidal congestion with a nutmeg-like appearance. Histologically, the lesion exhibited severe sinusoidal congestion with peliosis hepatis-like features. The widened sinusoidal space was outlined by markedly attenuated hepatic cords and filled with erythrocytes. The final diagnosis was oxaliplatin-induced SOS. The patient recovered completely and was relapse-free at the time of writing. PMID:27073565

    Purpose. Acute liver failure (ALF) treated with conservative therapy has a poor prognosis, although individual survival varies greatly. In these patients, the eligibility for liver transplantation must be quickly decided. The aim of this study was to assess the role of transjugular liver biopsy (TJLB) in the management of patients with the clinical presentation of ALF. Methods. Seventeen patients with the clinical presentation of ALF were referred to our institution during a 52 month period. A TJLB was performed using the Cook Quick-Core needle biopsy. Clinical data, procedural complications, and histologic findings were evaluated. Results. Causes of ALF were virus hepatitis B infection in 7 patients, drug toxicity in 4, mushroom in 1, Wilson's disease in 1, and unknown origin in 4. TJLB was technically successful in all patients without procedure-related complications. Tissue specimens were satisfactory for diagnosis in all cases. In 14 of 17 patients the initial clinical diagnosis was confirmed by TJLB; in 3 patients the initial diagnosis was altered by the presence of unknown cirrhosis. Seven patients with necrosis <60% were successfully treated with medical therapy; 6 patients with submassive or massive necrosis ({>=}85%) were treated with liver transplantation. Four patients died, 3 had cirrhosis, and 1 had submassive necrosis. There was a strict statistical correlation (r = 0.972, p < 0.0001) between the amount of necrosis at the frozen section examination and the necrosis found at routine histologic examination. The average time for TJLB and frozen section examination was 80 min. Conclusion. In patients with the clinical presentation of ALF, submassive or massive liver necrosis and cirrhosis are predictors of poor prognosis. TLJB using an automated device and frozen section examination can be a quick and effective tool in clinical decision-making, especially in deciding patient selection and the best timing for liver transplantation.

    Background/Aims Many parasites induce changes in the lipid profiles of the host. Cholesterol increases the virulence of Entamoeba histolytica in animal models and in vitro culture. This study aimed to determine, in patients with an amebic liver abscess, the correlation between cholesterol and other features, such as the size and number of abscesses, standard hematological and serum chemistry profiles, liver tests, and duration of hospital stay. Methods A total of 108 patients with an amebic liver abscess and 140 clinically healthy volunteers were investigated. Cholesterol and triglycerides were measured in the sera. The data from medical observations and laboratory tests were obtained from the clinical records. Results A total of 93% of patients with an amebic liver abscess showed hypocholesterolemia not related to any of the studied parameters. Liver function tests correlated with the size of the abscess. The most severe cases of amebic liver disease or death were found in patients whose cholesterol levels continued to decrease despite receiving antiamebic treatment and hospital care. Conclusions Our results show that the hypocholesterolemia observed in patients with an amebic liver abscess is not related to any of the clinical and laboratory features analyzed. This is the first study relating hypocholesterolemia to severity of hepatic amebiasis. PMID:25071907

    Objectives The incidence of cancer among the indigenous Sami people of Northern Finland is lower than among the Finnish general population. The survival of Sami cancer patients is not known, and therefore it is the object of this study. Study design The cohort consisted of 2,091 Sami and 4,161 non-Sami who lived on 31 December 1978 in the two Sami municipalities of Inari and Utsjoki, which are located in Northern Finland and are 300–500 km away from the nearest central hospital. The survival experience of Sami and non-Sami cancer patients diagnosed in this cohort during 1979–2009 was compared with that of the Finnish patients outside the cohort. Methods The Sami and non-Sami cancer patients were matched to other Finnish cancer patients for gender, age and year of diagnosis and for the site of cancer. An additional matching was done for the stage at diagnosis. Cancer-specific survival analyses were made using the Kaplan–Meier method and Cox regression modelling. Results There were 204 Sami and 391 non-Sami cancer cases in the cohort, 20,181 matched controls without matching with stage, and 7,874 stage-matched controls. In the cancer-specific analysis without stage variable, the hazard ratio for Sami was 1.05 (95% confidence interval 0.85–1.30) and for non-Sami 1.02 (0.86–1.20), indicating no difference between the survival of those groups and other patients in Finland. Likewise, when the same was done by also matching the stage, there was no difference in cancer survival. Conclusion Long distances to medical care or Sami ethnicity have no influence on the cancer patient survival in Northern Finland. PMID:22765936

    It is widely believed that the presence of a malignancy causes increased energy expenditure in the cancer patient. To test this hypothesis, resting energy expenditure (REE) was measured by bedside indirect calorimetry in 200 heterogeneous hospitalized cancer patients. Measured resting energy expenditure (REE-M) was compared with expected energy expenditure (REE-P) as defined by the Harris-Benedict formula. The study population consisted of 77 males and 123 females with a variety of tumor types: 44% with gastrointestinal malignancy, 29% with gynecologic malignancy, and 19% with a malignancy of genitourinary origin. Patients were classified as hypometabolic (REE less than 90% of predicted), normometabolic (90-110% of predicted) or hypermetabolic (greater than 110% of predicted). Fifty-nine per cent of patients exhibited aberrant energy expenditure outside the normal range. Thirty-three per cent were hypometabolic (79.2% REE-P), 41% were normometabolic (99.5% REE-P), and 26% were hypermetabolic (121.9% REE-P) (p less than 0.001). Aberrations in REE were not due to age, height, weight, sex, nutritional status (% weight loss, visceral protein status), tumor burden (no gross tumor, local, or disseminated disease), or presence of liver metastasis. Hypermetabolic patients had significantly longer duration of disease (p less than 0.04) than normometabolic patients (32.8 vs. 12.8 months), indicating that the duration of a malignancy may have a major impact upon energy metabolism. Cancer patients exhibit major aberrations in energy metabolism, but are not uniformly hypermetabolic. Energy expenditure cannot be accurately predicted in cancer patients using standard predictive formulae. Images Fig. 2. Fig. 3. PMID:6824369

  8. Non-viral causes of liver cancer: does obesity led inflammation play a role?

    Liver cancer is the fifth most common cancer worldwide and the third most common cause of cancer mortality. Hepatocellular carcinoma (HCC) accounts for around 90% of primary liver cancers. Chronic infection with hepatitis B and hepatitis C viruses are two of most common causes of liver cancer. However, there are non-viral factors that are associated with liver cancer development. Numerous population studies have revealed strong links between obesity and the development of liver cancer. Obesity can alter hepatic pathology, metabolism and promote inflammation, leading to nonalcoholic fatty liver disease (NAFLD) and the progression to the more severe form, non-alcoholic steatohepatitis (NASH). NASH is characterised by prominent steatosis and inflammation, and can lead to HCC. Here, we discuss the role of obesity in inflammation and the principal signalling mechanisms involved in HCC formation.

    Hepatocellular carcinoma (HCC) is the most common form of primary liver cancer, yet no effective therapeutics exist. This review provides an overview of the recent development of recombinant immunotoxins for the treatment of glypican-3 (GPC3) expressing HCC. GPC3 is a cell surface heparan sulfate proteoglycan that is overexpressed in HCC, but is absent from normal adult human tissues. Treatment of HCC with anti-GPC3 immunotoxins represents a new therapeutic option. Using phage display and hybridoma technologies, three high affinity antibodies (HN3, HS20 and YP7) have been generated against GPC3. Two of these antibodies (HN3 and HS20) have demonstrated the ability to inhibit Wnt/Yap signaling, leading to a reduction in liver cancer cell proliferation. By combining the HN3 antibody capable of inhibiting Wnt/Yap signaling with the protein synthesis inhibitory domain of the Pseudomonas exotoxin, a recombinant immunotoxin that exhibits a dual inhibitory mechanism was generated. This immunotoxin was found to be highly effective in the treatment of human HCCs in mouse xenograft models. Engineering of the toxin fragment to reduce the level of immunogenicity is currently being explored. The development of immunotoxins provides opportunities for novel liver cancer therapies.

    Abstract For chronic hepatitis B (CHB), alanine aminotransferase (ALT) ≥2 × upper limit of normal (ULN) is often used as a major criteria to initiate treatment in absence of cirrhosis, though patients with lower ALT may not be free from future risk of hepatocellular carcinoma (HCC). We aimed to examine the effect of antiviral therapy on HCC incidence based on ALT levels. We performed a retrospective study on 3665 patients consisting of United States and Taiwanese REVEAL-HBV cohort who were consecutive, treatment-naïve, noncirrhotic CHB patients aged ≥40 years. Patients were categorized by ALT cutoffs (≥2 × ULN vs <2 × ULN) and subgrouped by treatment status. Kaplan–Meier and Cox proportional hazards models were used to calculate cumulative incidence and hazard ratio (HR) of HCC adjusting for REACH-B scores. A total of 202 patients developed HCC. Antiviral treatment significantly reduced HCC risk: HR 0.24, 95% confidence interval 0.10–0.58; P = 0.001. HCC incidence per 100,000 person-years was significantly higher in untreated versus treated patients, even for those with ALT < 2 × ULN: 314.46 versus 0 per 100,000 person-years, P = 0.0042. For patients with Hepatitis B Virus (HBV) Deoxyribonucleic Acid (DNA) ≥ 2000 IU/mL, the number-needed-to-treat (NNT) were 15 and 14 to prevent 1 incident HCC at year 10 for patients with ALT < 2 × ULN and ≥2 × ULN, respectively. After adjustment by REACH-B score, antiviral treatment significantly decreased HCC incidence even in patients with ALT < 2 × ULN. NNT to prevent 1 incident HCC after 10 years of therapy was low (14–15) in patients with mildly elevated HBV DNA ≥ 2000 IU/mL regardless of ALT levels. PMID:27495067

    The median waiting time for patients with MELD ≥ 35 decreased from 18 days in 2012 to 9 days in 2014, after implementation of the Share 35 policy in June 2013. Similarly, mortality among candidates listed with MELD ≥ 35 decreased from 366 per 100 waitlist years in 2012 to 315 in 2014. The number of new active candidates added to the pediatric liver transplant waiting list in 2014 was 655, down from a peak of 826 in 2005. The number of prevalent candidates (on the list on December 31 of the given year) continued to decline, 401 active and 173 inactive. The number of deceased donor pediatric liver transplants peaked at 542 in 2008 and was 478 in 2014. The number of living donor liver pediatric transplants was 52 in 2014; most were from donors closely related to the recipients. Graft survival continued to improve among pediatric recipients of deceased donor and living donor livers. PMID:26755264

    Sexuality is a basic need for every human being as long as he or she is alive, irrespective of age or health status. Approximately 23,500 individuals are diagnosed with cancer each year in Israel and join the 120,000 cancer patients currently living in Israel. The results of cancer treatments are traditionally assessed and based on the outcome regarding mortality versus survival. An equally important aspect to be addressed in this assessment must relate to quality of life. One of the more painful insults to the quality of life of cancer patients relates to the deleterious effects on sexuality. This article aims to present physicians with the spectrum of sexuality-related issues which are encountered by cancer patients and their partners, starting from the moment of diagnosis, throughout the various stages of treatment and to provide basic knowledge. Many individuals contracting cancer have difficulty dealing with the issue of sexuality. They are typically embarrassed and feel uneasy when asking health care providers about such a non-life threatening issue. Partners similarly feel both shame and guilt. In many cases sexuality, intimacy and emotional attachment are important aspects and may be essential for survival. Addressing these issues during treatment can provide patients with a sense of security, avoiding embarrassment and further exacerbation of such problems. Unfortunately, little has been done to develop an optimal interventional program, although standard sexual treatments have often been applied. Prospective clinical research and outcomes are missing. The physician can use the well-known PLISSIT model (1978): to provide sexuality involvement on different levels. The very new BETTER model (2004) can help emphasize that cancer treatment and the disease have an influence on intimacy and sexuality.

    Liver transplantation is associated with a significantly increased risk of de novo malignancies, but for renal cancer this risk is less clear. We therefore performed a meta-analysis of published studies to determine whether renal cancer risk in liver transplant recipients (LTRs) was increased. To obtain a more precise conclusion, a systematic search was performed in PubMed and Web of Science databases until June 10, 2015. Standardized incidence ratio (SIR) corresponding 95% confidence interval (CI) were used to estimate risk of renal cancer in LTRs. Heterogeneity test, sensitivity analysis, and publishing bias were also performed. We identified 8 eligible studies and performed a meta-analysis on data of 49,654 LTRs with a total follow-up of 121,514.6 patient-years. The SIR for renal cancer was identified a 3.275-fold higher SIR (95% CI: 1.857-5.777; P < 0.001) in LTRs compared with the general population. This systematic review and meta-analysis demonstrated that the LTRs was associated with a significant increase in the incidence of renal cancer. Such association suggests that yearly routine post-transplant surveillance is need for renal cancer in LTRs.

    This study was conducted to clarify the role of cytoglobin (Cygb), a globin expressed in hepatic stellate cells (HSCs), in the development of liver fibrosis and cancer in nonalcoholic steatohepatitis (NASH). Cygb expression was assessed in patients with NASH and hepatocellular carcinoma. Mouse NASH model was generated in Cygb-deficient (Cygb(-/-)) or wild-type (WT) mice by giving a choline-deficient amino acid-defined diet and, in some of them, macrophage deletion and N-acetyl cysteine treatment were used. Primary-cultured mouse HSCs isolated from WT (HSCs(Cygb-wild)) or Cygb(-/-) (HSCs(Cygb-null)) mice were characterized. As results, the expression of CYGB was reduced in patients with NASH and hepatocellular carcinoma. Choline-deficient amino acid treatment for 8 weeks induced prominent inflammation and fibrosis in Cygb(-/-) mice, which was inhibited by macrophage deletion. Surprisingly, at 32 weeks, despite no tumor formation in the WT mice, all Cygb(-/-) mice developed liver cancer, which was ameliorated by N-acetyl cysteine treatment. Altered expression of 31 genes involved in the metabolism of reactive oxygen species was notable in Cygb(-/-) mice. Both HSCs(Cygb-null) and Cygb siRNA-transfected-HSCs(Cygb-wild) exhibited the preactivation condition. Our findings provide important insights into the role that Cygb, expressed in HSCs during liver fibrosis, plays in cancer development with NASH. PMID:25665792

    Neurological symptoms in cancer patients have a great impact on quality of life and need an interdisciplinary approach. They lead to significant impairment in activities of daily living (gait disorders, dizziness), a loss of patients independency (vegetative disturbances, wheel-chair dependency) and interfere with social activities (ban of driving in case of epilepsy). In this article we describe three main and serious neurological problems in the context of oncological patients. These are chemotherapy-induced polyneuropathy, malignant spinal cord compression and epileptic seizures. Our aim is to increase the awareness of neurological complications in cancer patients to improve patients care.

    Alcohol dependence represents a chronic and relapsing disease affecting nearly 10% of the general population both in the United States and in Europe, with a widespread burden of morbidity and mortality. Alcohol dependence represents the most common cause of liver damage in the Western Countries. Although alcoholic liver disease is associated primarily with heavy drinking, continued alcohol consumption, even in low doses after the onset of liver disease, increases the risk of severe consequences, including mortality. Consequently the ideal treatment of patients affected by alcohol dependence and alcoholic liver disease should aim at achieving long-term total alcohol abstinence and preventing relapse. The aim of the present review is to provide an update on the management of alcohol dependence in patients with alcoholic liver disease. Increasing evidences suggests the usefulness of psychosocial interventions and medications combined in order to reduce alcohol intake, promote abstinence and prevent relapse in alcohol dependent patients. Disulfiram, naltrexone and acamprosate have been approved for this indication; gamma-hydroxybutyric acid (GHB) is approved in Italy and Austria. However, these drugs have not been tested in patients with advanced liver disease. Amongst other emerging pharmacotherapies for alcoholism, topiramate, ondansetron, and baclofen seem the most promising ones. Both topiramate and ondansetron hold a safe profile in alcoholic patients; however, none of them has been tested in alcoholic patients with advanced liver disease. To date, baclofen represents the only anti-craving medication formally tested in a randomized clinical trial in alcoholic patients affected by liver cirrhosis, although additional confirmatory studies are warranted.

    The development of liver cirrhosis and portal hypertension (PH), one of its major complications, are structural and functional alterations of the liver, occurring in many patients with chronic liver diseases (CLD). Actually the progressive deposition of hepatic fibrosis has a key role in the prognosis of CLD patients. The subsequent development of PH leads to its major complications, such as ascites, hepatic encephalopathy, variceal bleeding and decompensation. Liver biopsy is still considered the reference standard for the assessment of hepatic fibrosis, whereas the measurement of hepatic vein pressure gradient is the standard to ascertain the presence of PH and upper endoscopy is the method of choice to detect the presence of oesophageal varices. However, several non-invasive tests, including elastographic techniques, are currently used to evaluate the severity of liver disease and predict its prognosis. More recently, the measurement of the spleen stiffness has become particularly attractive to assess, considering the relevant role accomplished by the spleen in splanchnic circulation in the course of liver cirrhosis and in the PH. Moreover, spleen stiffness as compared with liver stiffness better represents the dynamic changes occurring in the advanced stages of cirrhosis and shows higher diagnostic performance in detecting esophageal varices. The aim of this review is to provide an exhaustive overview of the actual role of spleen stiffness measurement as assessed by several elastographic techniques in evaluating both liver disease severity and the development of cirrhosis complications, such as PH and to highlight its potential and possible limitations.

    Liver cirrhosis is a major cause of mortality worldwide, often with severe sepsis as the terminal event. Over the last two decades, several studies have reported that in septic patients the adrenal glands respond inappropriately to stimulation, and that the treatment with corticosteroids decreases mortality in such patients. Both cirrhosis and septic shock share many hemodynamic abnormalities such as hyperdynamic circulatory failure, decreased peripheral vascular resistance, increased cardiac output, hypo-responsiveness to vasopressors, increased levels of proinflammatory cytokines [interleukine(IL)-1, IL-6, tumor necrosis factor-alpha] and it has, consequently, been reported that adrenal insufficiency (AI) is common in critically ill cirrhotic patients. AI may also be present in patients with stable cirrhosis without sepsis and in those undergoing liver transplantation. The term hepato-adrenal syndrome defines AI in patients with advanced liver disease with sepsis and/or other complications, and it suggests that it could be a feature of liver disease per se, with a different pathogenesis from that of septic shock. Relative AI is the term given to inadequate cortisol response to stress. More recently, another term is used, namely "critical illness related corticosteroid insufficiency" to define "an inadequate cellular corticosteroid activity for the severity of the patient's illness". The mechanisms of AI in liver cirrhosis are not completely understood, although decreased levels of high-density lipoprotein cholesterol and high levels of proinflammatory cytokines and circulatory endotoxin have been suggested. The prevalence of AI in cirrhotic patients varies widely according to the stage of the liver disease (compensated or decompensated, with or without sepsis), the diagnostic criteria defining AI and the methodology used. The effects of corticosteroid therapy on cirrhotic patients with septic shock and AI are controversial. This review aims to summarize the

    Ampullary carcinoma is an uncommon gastrointestinal disease. Its natural history is often characterized by the occurrence of liver metastases. Among patients who undergo pancreatoduodenectomy, those presenting with lymph nodes involvement are more prone to early distant disease relapse. In this report, a patient previously diagnosed with ampullary carcinoma had been treated with curative surgery. After subsequent adjuvant gemcitabine, the patient developed significant myelotoxicity and suffered from a single liver metastasis a few months later. A hepatic intra-arterial mitomycin plus fluorouracil-based chemotherapy was administered in order to avoid any serious systemic toxicity. The treatment was well tolerated and no serious side effects occurred. Extra-hepatic cancer relapse, involving intra-thoracic and abdominal lymph nodes, was observed not long after the initial intra-hepatic almost complete response. In conclusion, the locoregional chemotherapy administration was effective in overcoming any systemic toxicities and showed activity against the liver metastasis but it did not prevent extra-hepatic cancer dissemination.

Although advances in the intensive care management of patients with ALF have improved survival, the prognosis of ALF remains poor, with a 33% mortality rate and a 25% liver transplant rate in the United States. ALF adversely affects nearly every organ system, with most deaths occurring from sepsis and subsequent multiorgan system failure, and cerebral edema, resulting in intracranial hypertension (ICH) and brainstem herniation. Unfortunately, the optimal management of ALF remains poorly defined, and practices are often based on local experience and case reports rather than on randomized, controlled clinical trials. The paramount question in any patient presenting with ALF remains defining an etiology, since specific antidotes can save lives and spare the liver. This article will consider recent advances in the assignment of an etiology, the administration of etiology-specific treatment to abate the liver injury, and the management of complications (eg, infection, cerebral edema, and the bleeding diathesis) in patients with ALF. New data on the administration of N-acetylcysteine to patients with non-acetaminophen ALF, the treatment of ICH, and assessment of the need for liver transplantation will also be presented.

    Outcomes of hepatocellular carcinoma (HCC) lesions >3.0 cm in size including Barcelona Clinic Liver Cancer (BCLC) stage B after radiofrequency ablation (RFA) with a single electrode remain unsatisfactory. This study aimed to investigate the outcomes of RFA with multiple electrodes (ME-RFA) for HCC tumors 3.1-7.0 cm in size and BCLC stage B. This retrospective study included 70 consecutive patients with 58 medium- (3.1-5.0 cm) and 17 large- (5.1-7.0 cm) sized HCCs after ME-RFA using a controller. Outcomes in terms of complete response, primary technique effectiveness, local tumor progression, and overall survival were investigated. After 1-4 applications of ME-RFA, the rates of complete response and PTE in medium-sized tumors were 79.3% and 91.4%, respectively, and in large tumors were 76.5% and 94.1%, respectively. Overall, the major complication rate was 5.7%. After a median 21-month follow-up period, both two- and three-year estimated overall survival rates were above 80%. There were no significant differences in overall survival and local tumor progression rates between medium- and large-size tumors and among BCLC stages A, B1 and B2. A complete response to ME-RFA was the only significant factor associated with improved survival (p=0.008). In conclusion, ME-RFA can effectively treat 3.1-7.0-cm sized HCCs with a comparable outcome between medium- and large-size tumors and among BCLA stages A to B2. PMID:26989656

    Background: The incidence of liver cancer has been increasing in Canada over the past decade, as has cyanobacterial contamination of Canadian freshwater lakes and drinking water sources. Cyanotoxins released by cyanobacteria have been implicated in the pathogenesis of liver cancer. Objective: To determine whether a geographic association exists between liver cancer and surrogate markers of cyanobacterial contamination of freshwater lakes in Canada. Methods: A negative binomial regression model was employed based on previously identified risk factors for liver cancer. Results: No association existed between the geographic distribution of liver cancer and surrogate markers of cyanobacterial contamination. As predicted, significant associations existed in areas with a high prevalence of hepatitis B virus infection, large immigrant populations and urban residences. Discussion and Conclusions: The results of this study suggest that cyanobacterial contamination of freshwater lakes does not play an important role in the increasing incidence of liver cancer in Canada.

    Liver cirrhosis is a major cause of mortality worldwide, often with severe sepsis as the terminal event. Over the last two decades, several studies have reported that in septic patients the adrenal glands respond inappropriately to stimulation, and that the treatment with corticosteroids decreases mortality in such patients. Both cirrhosis and septic shock share many hemodynamic abnormalities such as hyperdynamic circulatory failure, decreased peripheral vascular resistance, increased cardiac output, hypo-responsiveness to vasopressors, increased levels of proinflammatory cytokines [interleukine(IL)-1, IL-6, tumor necrosis factor-alpha] and it has, consequently, been reported that adrenal insufficiency (AI) is common in critically ill cirrhotic patients. AI may also be present in patients with stable cirrhosis without sepsis and in those undergoing liver transplantation. The term hepato-adrenal syndrome defines AI in patients with advanced liver disease with sepsis and/or other complications, and it suggests that it could be a feature of liver disease per se, with a different pathogenesis from that of septic shock. Relative AI is the term given to inadequate cortisol response to stress. More recently, another term is used, namely “critical illness related corticosteroid insufficiency” to define “an inadequate cellular corticosteroid activity for the severity of the patient’s illness”. The mechanisms of AI in liver cirrhosis are not completely understood, although decreased levels of high-density lipoprotein cholesterol and high levels of proinflammatory cytokines and circulatory endotoxin have been suggested. The prevalence of AI in cirrhotic patients varies widely according to the stage of the liver disease (compensated or decompensated, with or without sepsis), the diagnostic criteria defining AI and the methodology used. The effects of corticosteroid therapy on cirrhotic patients with septic shock and AI are controversial. This review aims to summarize

    Background Screening colonoscopy is a standard part of the liver transplant (LT) evaluation process. We aimed to evaluate the yield of screening colonoscopy and determine whether non-alcoholic fatty liver disease (NAFLD) was associated with an increased risk of colorectal neoplasia. Methods We retrospectively assessed all patients who completed LT evaluation at our center between 1/2008-12/2012. Patients <50 years old and those without records of screening colonoscopy, or with greater than average colon cancer risk were excluded. Results A total of 1,102 patients were evaluated, 591 met inclusion criteria and were analyzed. The mean age was 60 years, 67% were male, 12% had NAFLD and 88% had other forms of chronic liver disease. Overall, 42% of patients had a polyp found on colonoscopy: 23% with adenomas, 14% with hyperplastic polyps and with 1% inflammatory polyps. In the final multivariable model controlling for age, NAFLD [odds ratio (OR) 2.41, P=0.001] and a history of significant alcohol use (OR 1.69, P=0.004) were predictive of finding a polyp on colonoscopy. In addition, NAFLD (OR 1.95, P=0.02), significant alcohol use (OR 1.70, P=0.01) and CTP class C (OR 0.57, P=0.02) were associated with adenoma, controlling for age. Conclusions Screening colonoscopy in patients awaiting LT yields a high rate of polyp (43%) and adenoma (22%) detection, perhaps preventing the accelerated progression to carcinoma that can occur in immunosuppressed post-LT patients. Patients with NAFLD may be at a ~2 fold higher risk of adenomas and should be carefully evaluated prior to LT. PMID:26487938

    We report a gene expression study aimed at the identification of genes differentially expressed in the livers of Hispanic patients infected with hepatitis C virus (HCV). Six uninfected controls were compared with 14 HCV(+) patients in which the liver biopsies were obtained at the time of diagnosis. Among the latter, five patients were also analyzed 4 weeks after the onset of standard anti-HCV therapy (pegylated interferon-α + ribavirin). We identified many genes up- or down-regulated by the infection with HCV in the human livers. When these genes were subjected to pathway analysis, several prominent pathways were revealed including many interferon (IFN)-inducible pathways as well as immune cell trafficking, inflammation, anti-microbial responses, and even cancer. We detected expression of many genes that have previously been associated with HCV infection, as well as several novel genes including CD47. The genes induced by HCV infection showed large expression changes, whereas the genes induced by the IFN-α combination therapy were relatively few (including MX2, ORMDL3, GPAM, KOPX18, TMEM56, and HBP1) and they reflected relatively small expression changes. This is the first study to identify changes in gene expression in livers of HCV(+) Hispanic patients and the first to identify genes induced by anti-HCV combination therapy in the human liver.

    Transarterial chemoembolization (TACE) is a form of intra-arterial catheter-based chemotherapy that selectively delivers high doses of cytotoxic drug to the tumor bed combining with the effect of ischemic necrosis induced by arterial embolization. Chemoembolization and radioembolization are at the core of the treatment of liver hepatocellular carcinoma (HCC) patients who cannot receive potentially curative therapies such as transplantation, resection or percutaneous ablation. TACE for liver cancer has been proven to be useful in local tumor control, to prevent tumor progression, prolong patients’ life and control patient symptoms. Recent evidence showed in patients with single-nodule HCC of 3 cm or smaller without vascular invasion, the 5-year overall survival (OS) with TACE was similar to that with hepatic resection and radiofrequency ablation. Although being used for decades, Lipiodol® (Lipiodol® Ultra Fluid®, Guerbet, France) remains important as a tumor-seeking and radio-opaque drug delivery vector in interventional oncology. There have been efforts to improve the delivery of chemotherapeutic agents to tumors. Drug-eluting bead (DEB) is a relatively novel drug delivery embolization system which allows for fixed dosing and the ability to release the anticancer agents in a sustained manner. Three DEBs are available, i.e., Tandem® (CeloNova Biosciences Inc., USA), DC-Beads® (BTG, UK) and HepaSphere® (BioSphere Medical, Inc., USA). Transarterial radioembolization (TARE) technique has been developed, and proven to be efficient and safe in advanced liver cancers and those with vascular complications. Two types of radioembolization microspheres are available i.e., SIR-Spheres® (Sirtex Medical Limited, Australia) and TheraSphere® (BTG, UK). This review describes the basic procedure of TACE, properties and efficacy of some chemoembolization systems and radioembolization agents which are commercially available and/or currently under clinical evaluation.

    Cancer patients have the highest incidence of protein-calorie malnutrition seen in hospitalized patients, with significant malnutrition occurring in more than 30% of cancer patients undergoing major upper gastrointestinal procedures. Clinically significant malnutrition occurs as a result of diminished nutrient intake, increased nutrient losses, and tumor-induced derangements in host metabolism. In the absence of adequate exogenous nutrients, the body utilizes endogenous substrates to satisfy the ongoing requirements of both host and tumor for energy and protein. In those patients with malignant obstruction of the gastrointestinal tract, the tumor itself may induce diminished nutrient intake. Present day treatment modalities including gastrointestinal resection, chemotherapy, and radiotherapy compound these metabolic derangements, further increasing the risk of postoperative morbidity and death. The presence of malnutrition in cancer patients has prognostic importance. In a review of more than 3000 cancer patients, DeWys and colleagues identified significantly improved survival in those patients without weight loss compared with those had lost 6% of their body weight (Am J Med 69:491-497, 1980). Other investigators have noted increased postoperative morbidity and mortality associated with malnutrition. Early hypotheses suggested that reversal of weight loss would improve survival. The development and refinements of enteral and parenteral nutrition have provided the opportunity for studying the relationship between nutritional supplementation and postoperative prognosis. Nutrition support is therefore often instituted to improve nutritional status and thereby reduce the risks of postoperative complications. This article addresses the beneficial role of preoperative nutrition therapy in cancer patients.

    Spontaneously rupture of hepatocellular carcinoma is a life threatening and worse prognosis. Not only the lower rate of resection and hemodynamic unstable, but also the hepatic failure and recurrence. Distilled water irrigation had been applied in several cancer surgeries including colon, stomach, breast, ovary, and bladder; thus had good results in lowering the tumor spreading. We applied distilled water peritoneal lavage after liver resection in patients with spontaneous rupture of hepatocellular carcinoma to define the influence of prognosis. Thirteen patients with spontaneous ruptured hepatocellular carcinoma underwent distilled water peritoneal lavage after curative liver resection (Group A). Nineteen patients with spontaneous ruptured hepatocellular carcinoma did not undergo distilled water peritoneal lavage after curative liver resection (Group B). There were 11 patients of tumor recurrence in Group B; 2 in Group A. The mean disease-free time of Group B was 2.05 +/- 0.74 years; for Group A it was 3.59 +/- 0.60 (P = 0.045). Peritoneal lavage in this series resulted in significantly better survival time for the patients in Group A (P = 0.0158). That implies distilled water peritoneal lavage during liver resection would retard the tumor recurrence and further improve the survival rate in patients with spontaneously ruptured hepatocellular carcinoma.

    The present study aimed to investigate the impact of postoperative antiviral treatment on tumor recurrence, fatalities and survival of patients with chronic hepatitis B virus (HBV) infection-related primary hepatocellular carcinoma (HCC). A systematic meta-analysis was performed. All the studies comparing nucleos(t)ide analogues (NAs) versus placebo or no treatment were considered. The results were expressed as relative ratio (RR) for 1-, 3- and 5-year recurrence-free survival (RFS) and overall survival (OS), recurrence HCC and fatalities with 95% confidence intervals (CI) using STATA 11.0. In total, 15 trials with 7,619 patients were included. There were significant improvements for 1-, 3- and 5-year RFS (RR, 1.09; P=0.003; RR, 1.202; P<0.001; and RR, 1.219; P=0.02; respectively) and in 3- and 5-year OS (RR, 1.087, P=0.006; and RR, 1.186; P<0.001) in the NAs group compared with the control group. Sensitivity analyses confirmed the robustness of the results. In addition, the significantly high rate of recurrence HCC and fatalities existed in the control group (RR, 1.301; P=0.002; and RR, 1.816, P<0.001). One study was for an entecavir (ETV)-treated group compared with an adefovir (ADV)-treated group and lamivudine (LAM)-treated group. The 3-year disease-free survival rate for the ETV group was significantly better compared with the ADV and LAM groups [hazard ratio (HR), 0.810; P=0.049; and HR, 0.737; P=0.007]. The present study demonstrated the beneficial effects of NAs therapy following curative treatment of HBV-related HCC. ETV may be the superior choice compared to ADV or LAM for the antiviral treatment. PMID:26807227

    Although cancer is the second leading cause of death among persons 65 years and older, there is a paucity of clinical trial data about the effectiveness and harms of cancer screening in this population. Given the heterogeneous nature of the older population, cancer screening in these patients should not be based on age alone. Studies suggest that a life expectancy of at least 10 years is necessary to derive a survival benefit from screening for breast and colorectal cancers; therefore, screening for these cancers is not recommended in those with a life expectancy of less than 10 years. Prostate cancer screening, if performed at all, should not be performed after 69 years of age. Cervical cancer screening may be stopped after 65 years of age if the patient has an adequate history of negative screening results. An individualized approach to cancer screening decisions involves estimating life expectancy, determining the potential benefits and harms of screenings, and weighing those benefits and harms in relation to the patient's values and preferences.

  18. Stop feeding cancer: pro-inflammatory role of visceral adiposity in liver cancer.

    Zhao, Jun; Lawless, Matthew W

    2013-12-01

    Liver cancer is the fifth most common cancer in the world with an estimated over half a million new cases diagnosed every year. Due to the difficulty in early diagnosis and lack of treatment options, the prevalence of liver cancer continues to climb with a 5-year survival rate of between 6% and 11%. Coinciding with the rise of liver cancer, the prevalence of obesity has rapidly increased over the past two decades. Evidence from epidemiological studies demonstrates a higher risk of hepatocellular carcinoma (HCC) in obese individuals. Obesity is recognised as a low-grade inflammatory disease, this is of particular relevance as inflammation has been proposed as the seventh hallmark of cancer development with abdominal visceral adiposity considered as an important source of pro-inflammatory stimuli. Emerging evidence points towards the direct role of visceral adipose tissue rather than generalised body fat in carcinogenesis. Cytokines such as IL-6 and TNF-α secreted from visceral adipose tissue have been demonstrated to induce a chronic inflammatory condition predisposing the liver to a protumourigenic milieu. This review focuses on excess visceral adiposity rather than simple obesity; particularly adipokines and their implications for chronic inflammation, lipid accumulation, insulin resistance, Endoplasmic Reticulum (ER) stress and angiogenesis. Evidence of molecular signalling pathways that may give rise to the onset and progression of HCC in this context are depicted. Delineation of the pro-inflammatory role of visceral adiposity in liver cancer and its targeting will provide better rational and therapeutic approaches for HCC prevention and elimination. The concept of a central role for metabolism in cancer is the culmination of an effort that began with one of the 20th century's leading biochemists and Nobel laureate of 1931, Otto Warburg.

    As many as 25 % of colorectal cancer (CRC) patients have liver metastases at presentation. However, the optimal strategy for resectable synchronous colorectal liver metastasis remains controversial. Despite the increasing use of laparoscopy in colorectal and liver resections, combined laparoscopic resection of the primary CRC and synchronous liver metastasis is rarely performed. The potential benefits of this approach are the possibility to perform a radical operation with small incisions, earlier recovery, and reduction in costs. The aim of this study was to review the literature on feasibility and short-term results of simultaneous laparoscopic resection. We conducted a systematic search of all articles published until February 2013. Search terms included: hepatectomy [Mesh], "liver resection," laparoscopy [Mesh], hand-assisted laparoscopy [Mesh], surgical procedures, minimally invasive [Mesh], colectomy [Mesh], colorectal neoplasms [Mesh], and "colorectal resections." No randomized trials are available. All data have been reported as case reports, case series, or case-control studies. Thirty-nine minimally invasive simultaneous resections were identified in 14 different articles. There were 9 (23 %) major hepatic resections. The most performed liver resection was left lateral sectionectomy in 26 (67 %) patients. Colorectal resections included low rectal resections with total mesorectal excision, right and left hemicolectomies, and anterior resections. Despite the lack of high-quality evidence, the laparoscopic combined procedure appeared to be feasible and safe, even with major hepatectomies. Good patient selection and refined surgical technique are the keys to successful simultaneous resection. Simultaneous left lateral sectionectomy associated with colorectal resection should be routinely proposed. PMID:24057357

    Obesity is major health problem in the Asia-Pacific region. The proportion of people who are overweight and obese in the region has increased dramatically and is closely linked to the increasing affluence in the region. While the body mass index has been used as a yardstick in many published studies, it has been noted that Asian patients have a greater percentage body fat for a given body mass index and especially abdominal or visceral obesity. The association of obesity and cancers is intriguing and worrisome at the same time, as obesity is rising exponentially throughout the world especially in the Asia-Pacific region. Evidence of its association with gastrointestinal cancers is well documented and is reported with cardioesophageal, colorectal, liver, pancreatic, and gallbladder cancers. The strength of association varies between individual cancers but is of particular concern with colorectal cancer, which is perhaps the fastest emerging cancer in this region. Biological mechanisms for obesity-related carcinogenesis have been described, which includes insulin resistance and secretion of adipokines and chronic inflammation. A "dose-response" relationship between severity of excess body weight and risks of cancer has been reported. However, there is a paucity of data looking at a decrease in incidence of these cancers with a decrease in body weight with treatment, for example, bariatric surgery. Such studies will be difficult to perform and which would require a long period of longitudinal follow-up.

    We report a case of a 61-year-old man who presented with fatigue, abdominal pain and hepatomegaly. Computed tomography (CT) of the abdomen showed hepatomegaly and multiple hepatic lesions highly suggestive of metastatic diseases. Due to the endoscopic finding of colon ulcer, colon cancer with liver metastases was suspected. Biochemically a slight increase of transaminases, alkaline phosphatase and gammaglutamyl transpeptidase were present; α - fetoprotein, carcinoembryogenic antigen and carbohydrate 19-9 antigen serum levels were normal. Laboratory and instrumental investigations, including colon and liver biopsies revealed no signs of malignancy. In the light of spontaneous improvement of symptoms and CT findings, his personal history was revaluated revealing direct contact with pigs and their tissues. Diagnosis of leptospirosis was considered and confirmed by detection of an elevated titer of antibodies to leptospira. After two mo, biochemical data, CT and colonoscopy were totally normal.

    Fatty liver can present as focal, diffuse, heterogeneous, and multinodular forms. Being familiar with various patterns of steatosis can enable correct diagnosis. In patients with equivocal findings on ultrasonography, magnetic resonance imaging can be used as a problem solving tool. New techniques are promising for diagnosis and follow-up. We review imaging patterns of steatosis and new quantitative methods such as proton density fat fraction and magnetic resonance elastography for diagnosis of nonalcoholic fatty liver disease in children.

    Metastasis to the liver is a main factor in colorectal cancer mortality. Previous studies suggest that chronic psychological stress is important in cancer progression, but its effect on liver metastasis has not been investigated. To address this, we established a liver metastasis model in BALB/c nude mice to investigate the role of chronic stress in liver metastasis. Our data suggest that chronic stress elevates catecholamine levels and promotes liver metastasis. Chronic stress was also associated with increased tumor associated macrophages infiltration into the primary tumor and increased the expression of metastatic genes. Interestingly, β-blocker treatment reversed the effects of chronic stress on liver metastasis. Our results suggest the β-adrenergic signaling pathway is involved in regulating colorectal cancer progression and liver metastasis. Additionally, we submit that adjunctive therapy with a β-blocker may complement existing colorectal cancer therapies. PMID:26444281

    Although the effect of malnutrition on survival has been demonstrated by a number of studies, it is not clear whether malnutrition represents an independent risk factor in patients with liver disease. We studied 212 hospitalized patients with liver cirrhosis who were followed clinically for 2 y or until death. Body fat and muscle mass were evaluated by triceps skinfold thickness (TSF) and midarm muscle circumference (MAMC), respectively. Multivariate analysis according to Cox's model assessed the predictive power of nutritional parameters on survival. Thirty-four percent of patients had severe malnutrition as determined by MAMC and/or TSF below the 5th percentile and 20% had moderate malnutrition (MAMC and/or TSF < 10th percentile). Twenty-six percent of patients were overnourished (MAMC and/or TSF > 75th percentile). Severely and moderately malnourished patients had lower survival rates than normal and overnourished patients. When analyzed with Cox's regression analysis, severe depletion of muscle mass and body fat were found to be independent predictors of survival. The inclusion of MAMC and TSF in the Child-Pugh score, the prognostic score used most with liver disease, improved its prognostic accuracy. The prognostic power of MAMC was higher than that of TSF. These data demonstrate that malnutrition is an independent predictor of survival in patients with liver cirrhosis. The inclusion of anthropometric measures in the assessment of these patients might provide better prognostic information. PMID:11399401

Results: The mRNA level of Th1-specific TF T-bet in HCC-group was significantly lower than that of C-group (52.34±34.07 VS 104.01±56.00, P<0.01); the mRNA level of Th2-specifc TF, GATA-3, in HCC group was significantly higher than that in C-group (1.38±1.15 VS 0.58±0.65, P<0.05) and T-bet mRNA/GATA-3 mRNA ratio was significantly lower in HCC-group than in C-group (86.01±116.71 VS 461.88±708.81, P<0.05). The mRNA level of Th17-specific TF RORγt in HCC-group was significantly higher than that of C-group (72.32±32.82 VS 33.07±22.86, P<0.01). Treg-specific TF FOXP3 mRNA level was significant higher in HCC-group than in C-group (3.17±1.59 VS 1.39±1.13, P<0.01) Conclusion: T-bet mRNA level was reduced whereas GATA-3 mRNA level was increased and T-bet/GATA-3 ratio was significantly reduced in PBMC, indicating that Th1/Th2 ratio was of imbalance at TF levels in PBMC of HCC, displaying Th2 thrift phenomena. The mRNA levels of RORγt and FOXP3 in PBMC of HCC were significantly increased, indicating the existence of a predominant phenomenon of Th17- and Treg-expressing PBMC in HCC. PMID:25552913

    Introduction Chronic Liver Disease (CLD) is a major cause of morbidity and mortality worldwide. It involves haemodynamic and metabolic complications. Hepatic Osteodystrophy is a metabolic bone disease that may occur in individuals with chronic liver disease. It can significantly affect morbidity and quality of life of these patients. Fractures are also associated with an excess mortality. It has been an under recognized and inadequately studied complication among Indian population. An early diagnosis is essential to correct reversible risk factors which predispose to bone mass loss. Aim To assess the prevalence of metabolic bone disease and identify the risk factors associated with hepatic osteodystrophy in patients with cirrhosis. Materials and Methods This was an observational, cross-sectional, hospital based study conducted at a medical college hospital. All patients more than 20-year-old, diagnosed with chronic liver disease/Cirrhosis were enrolled. They were subjected to haematological, biochemical investigations, evaluation of Vitamin D and other hormonal parameters. Bone Mineral Density (BMD) was estimated by Dual Energy X-ray Absorptiometry (DEXA). Results A total of 72 patients with mean age 50.04±11.24 years were included in the study. Amongst causes of chronic liver disease were alcoholic liver disease 22 (30.6%), CLD due to hepatitis B 24 (33.3%) and chronic hepatitis C 26 (36.1%). Twenty one (29.2%) patients had normal BMD while 51 (70.8%) had a low BMD. Out of these 51 patients, 36 (70.6%) were diagnosed of osteopenia and 15 (29.4%) others were found to have osteoporosis. Vitamin D levels and severity of liver disease had correlation with low BMD. Conclusion Low BMD is highly prevalent in patients with chronic liver disease of variable aetiologies. We advocate more randomised and prospective studies to be conducted on homogeneous groups with chronic liver disease in its various stages. In view of numerous therapeutic options available both for liver

    Background: Few studies are available regarding the prevalence of sleep disturbance in cirrhotic patients without overt hepatic encephalopathy. This study aimed to assess the prevalence of insomnia in stable liver cirrhosis patients who are attending the outpatient clinics at King Abdulaziz Medical City, Riyadh (KAMC-KFNGH). Methods: A cross-sectional study enrolled 200 stable patients with confirmed liver cirrhosis. We used the ICSD-2 definition to assess the prevalence of insomnia. We also collected information about sleep patterns, demographic data, the underlying cause of liver cirrhosis and the severity of liver cirrhosis using Child-Pugh scores (CTP). Results: The mean age was 58.9 (SD ± 12.2) years. Hepatitis C was the most common (60.2%) cause of liver cirrhosis among respondents. The prevalence of insomnia was 42% (84/200). Univarite analysis shows association between coffee intake and the presence of insomnia (56.9% vs. 35.9%, p-value = 0.006). The prevalence of insomnia was higher in hepatitis C (51.7%) compared to hepatitis B (36.8%) and other hepatitis (15%), p-value = 0.001. There was a significant relationship between severity of liver cirrhosis (CTP-A, CTP-C, CTP-B) and prevalence of insomnia: 55%, 36.1% and 32.1% respectively, p-value = 0.009. Insomniac patients were significantly older than non-insomniac (61.6 ± 12.0 vs. 57.0 ± 12.0 years, p = 0.008). Results from the multivariate stepwise analysis showed coffee intake (OR=2.7), hepatitis C (OR = 7.2), CTP-A (OR = 1.9), excessive daytime sleepiness (OR = 5.3) and short sleep duration (OR = 5.7) were the most strongly associated with the presence of insomnia. Conclusion: Our study showed a high prevalence of insomnia in patients with liver cirrhosis.

    Evidence regarding the outcomes of viral super-infection in patients with chronic liver disease and practical strategies for hepatitis A and B vaccination of these individuals are reviewed. Patients with acute hepatitis A and chronic hepatitis B have a more severe clinical course and a higher death rate compared with otherwise healthy individuals with hepatitis A, and these differences are most pronounced in older patients and those with histological evidence of chronic hepatitis or cirrhosis, rather than in asymptomatic hepatitis B carriers. Patients with acute hepatitis A super-infection and chronic hepatitis C have an increased risk of fulminant hepatitis and death. In addition, patients with other chronic liver diseases also appear to be at increased risk for more severe disease with superimposed hepatitis A. Patients with chronic hepatitis B and hepatitis C virus co-infection have more severe laboratory abnormalities, more severe histological disease, a greater frequency of cirrhosis and complications of cirrhosis, and a higher incidence of hepatocellular carcinoma. Vaccines for both hepatitis A and B are safe and effective if used early in the course of chronic liver disease. Hepatitis A and B vaccination should be part of the routine management of patients with chronic liver disease, preferably as early as possible in the natural course of their disease.

    Alcoholic liver disease (ALD) is the second most common diagnosis among patients undergoing liver transplantation (LT). The recovery results of patients transplanted for ALD are often at least as good as those of patients transplanted for other diagnoses and better than those suffering from hepatitis C virus, cryptogenic cirrhosis, or hepatocellular carcinoma. In the case of medically non-responding patients with severe acute alcoholic hepatitis or acute-on chronic liver failure, the refusal of LT is often based on the lack of the required alcohol abstinence period of six months. The obligatory abidance of a period of abstinence as a transplant eligibility requirement for medically non-responding patients seems unfair and inhumane, since the majority of these patients will not survive the six-month abstinence period. Data from various studies have challenged the 6-mo rule, while excellent survival results of LT have been observed in selected patients with severe alcoholic hepatitis not responding to medical therapy. Patients with severe advanced ALD should have legal access to LT. The mere lack of pre-LT abstinence should not be an obstacle for being listed. PMID:25892898

    Background: Micronutrients may influence the development or progression of liver cancer and liver disease. We evaluated the association of serum α-tocopherol, β-carotene, and retinol with incident liver cancer and chronic liver disease (CLD) mortality in a prospective cohort of middle-aged Finnish male smokers. Methods: Baseline and 3-year follow-up serum were available from 29 046 and 22 805 men, respectively. After 24 years of follow-up, 208 men were diagnosed with liver cancer and 237 died from CLD. Hazards ratios and 95% confidence intervals were calculated for highest vs lowest quartiles from multivariate proportional hazards models. Results: Higher β-carotene and retinol levels were associated with less liver cancer (β-carotene: 0.35, 0.22–0.55, P-trend <0.0001; retinol: 0.58, 0.39–0.85, P-trend=0.0009) and CLD mortality (β-carotene: 0.47, 0.30–0.75, P-trend=0.001; retinol: 0.55, 0.38–0.78, P-trend=0.0007). α-Tocopherol was associated with CLD mortality (0.63, 0.40–0.99, P-trend=0.06), but not with liver cancer (1.06, 0.64–1.74, P-trend=0.77). Participants with higher levels of β-carotene and retinol, but not α-tocopherol, at both baseline and year 3 had lower risk of each outcome than those with lower levels. Conclusions: Our findings suggest that higher concentrations of β-carotene and retinol are associated with incident liver cancer and CLD. However, such data do not indicate that supplementation should be considered for these diseases. PMID:25314058

    Background: Five-year survival after resection of colorectal cancer liver metastasis (CRLCM) is <30%. We recently found that aurora kinase A (AURKA) drives 20q gain-associated tumour progression and is associated with disease recurrence. This study evaluates the prognostic value of AURKA expression in CRCLM of patients who underwent liver resection. Methods: Tissue microarrays (TMAs) were generated using formalin-fixed paraffin-embedded CRCLM and matched primary tumour from a multi-institutional cohort of patients with CRCLM who underwent liver resection between 1990 and 2010. Tissue microarrays were stained for AURKA using immunohistochemistry, and a hazard rate ratio (HRR) for the association between overall survival (OS) and nuclear AURKA expression in CRCLM was calculated. Results were validated by 500-fold cross-validation. Results: The expression of AURKA was evaluated in CRCLM of 343 patients. High AURKA expression was associated with poor OS (HRR 1.55, P<0.01), with a cross-validated average HRR of 1.57 (P=0.02). Average HRR was adjusted for the established prognostic clinicopathological variables in a multivariate analysis (average HRR 1.66; P=0.02). The expression of AURKA in CRCLM was correlated to its expression in corresponding primary tumour (P<0.01). Conclusion: The expression of AURKA protein is a molecular biomarker with prognostic value for patients with CRCLM, independent of established clinicopathological variables. PMID:24104968

  17. Palliative care for patients with end-stage liver disease.

    Liver disease results in over four million physician visits and over 750,000 hospitalizations per year in the USA. Those with chronic liver disease frequently progress to cirrhosis, end-stage liver disease (ESLD), and death. Patients with ESLD experience numerous complications, including muscle cramps, confusion (hepatic encephalopathy), protein calorie malnutrition, muscle wasting, fluid overload (ascites, edema), bleeding (esophagogastric variceal hemorrhage), infection (spontaneous bacterial peritonitis), fatigue, anxiety, and depression. Despite significant improvements in palliation of these complications, patients still suffer reduced quality of life and must confront the fact that their disease will often inexorably progress to death. Liver transplantation is a valid option in this setting, increasing the duration of survival and palliating many of the symptoms. However, many patients die waiting for an organ or are not candidates for transplantation due to comorbid illness. Others receive a transplant but succumb to complications of the transplant itself. Patients and families must struggle with simultaneously hoping for a cure while facing a life-threatening illness. Ideally, the combination of palliative care with life-sustaining therapy can maximize the patients' quality and quantity of life. If it becomes clear that life-sustaining therapy is no longer an option, these patients are then already in a system to help them with end-of-life care.

    We report a case of early gastric cancer that was detected during surveillance of a pyogenic liver abscess caused by Streptococcus intermedius, an oral microbiota. Treatment with proton pump inhibitors can result in the alteration of gastric bacterial flora by altering intragastric acidity. This can place immunocompromised patients, such as those with diabetes mellitus and the elderly, at an increased risk for disease of the upper gastrointestinal tract to be a route of bacterial transmission. In this case, the patient developed a pyogenic liver abscess.

    Aberrant cell death/survival has a critical role in the development of hepatocellular carcinoma (HCC). Caspase-2, a cell death protease, limits oxidative stress and chromosomal instability. To study its role in reactive oxygen species (ROS) and DNA damage-induced liver cancer, we assessed diethylnitrosamine (DEN)-mediated tumour development in caspase-2-deficient (Casp2(-/-)) mice. Following DEN injection in young animals, tumour development was monitored for 10 months. We found that DEN-treated Casp2(-/-) mice have dramatically elevated tumour burden and accelerated tumour progression with increased incidence of HCC, accompanied by higher oxidative damage and inflammation. Furthermore, following acute DEN injection, liver injury, DNA damage, inflammatory cytokine release and hepatocyte proliferation were enhanced in mice lacking caspase-2. Our study demonstrates for the first time that caspase-2 limits the progression of tumourigenesis induced by an ROS producing and DNA damaging reagent. Our findings suggest that after initial DEN-induced DNA damage, caspase-2 may remove aberrant cells to limit liver damage and disease progression. We propose that Casp2(-/-) mice, which are more susceptible to genomic instability, are limited in their ability to respond to DNA damage and thus carry more damaged cells resulting in accelerated tumourigenesis.

    Alcoholism is currently listed as the third leading cause of death. Chronic alcohol consumption brings serious medical complications like gastrointestinal, cardiovascular, musculoskeletal, respiratory system disorders. Liver can be seriously damage by alcohol misuse. Alcoholic Liver Disease (ALD) is the first important warning sign of alcohol abuse. Since effective therapies for ALD are still limited, natural products in the treatment of ALD become very important. In this regard, there have been done very few clinical trials with poor results. Silymarin, glycyrrhizin, garlic show some promising results in ALD patients while the in vivo and in vitro studies with green tee, quercetin and curcumin indicate positive effect on patients with ALD.

    Survival after childhood cancer diagnosis has remarkably improved, but emerging evidence suggests that cancer-directed therapy may have adverse gastrointestinal late effects. We aimed to comprehensively assess the frequency of gastrointestinal and liver late effects among childhood cancer survivors and compare this frequency with the general population. Our population-based cohort study included all 1-year survivors of childhood and adolescent cancer in Denmark, Finland, Iceland, Norway and Sweden diagnosed from the 1940s and 1950s. Our outcomes of interest were hospitalization rates for gastrointestinal and liver diseases, which were ascertained from national patient registries. We calculated standardized hospitalization rate ratios (RRs) and absolute excess rates comparing hospitalizations of any gastrointestinal or liver disease and for specific disease entities between survivors and the general population. The study included 31,132 survivors and 207,041 comparison subjects. The median follow-up in the hospital registries were 10 years (range: 0-42) with 23% of the survivors being followed at least to the age of 40 years. Overall, survivors had a 60% relative excess of gastrointestinal or liver diseases [RR: 1.6, 95% confidence interval (CI): 1.6-1.7], which corresponds to an absolute excess of 360 (95% CI: 330-390) hospitalizations per 100,000 person-years. Survivors of hepatic tumors, neuroblastoma and leukemia had the highest excess of gastrointestinal and liver diseases. In addition, we observed a relative excess of several specific diseases such as esophageal stricture (RR: 13; 95% CI: 9.2-20) and liver cirrhosis (RR: 2.9; 95% CI: 2.0-4.1). Our findings provide useful information about the breadth and magnitude of late complications among childhood cancer survivors and can be used for generating hypotheses about potential exposures related to these gastrointestinal and liver late effects.

    We report a case of heparin-induced thrombocytopenia thrombosis (HITT) syndrome in a patient prophylactically treated with low molecular weight heparin. A 66-year-old men underwent radiofrequency-assisted partial liver resection for colorectal carcinoma liver metastases a year-and-a-half after he had been operated for rectal cancer. In the postoperative period, patient was prophilactically treated with reviparin sodium. On the 8th postoperative day, the platelet count decreased by more than 50% without clinical signs of thrombosis. HITT syndrome was suspected on the 19th postoperative day, after iliacofemoropopliteal thrombosis had developed, and related diagnosis was supported by the strongly positive particle gel agglutination technique immunoassay. Heparin was withdrawn and alternative anticoagulant, danaparoid sodium, was introduced in therapeutic doses. Despite delayed recognition, favorable clinical outcome was achieved. HITT syndrome should be considered with priority among the possible causes of thrombocytopenia in a surgical patient on heparin. PMID:22519199

    Hepatocellular carcinoma (HCC) is one of the most common malignancies leading to high mortality rates in the general population and the sixth most common cancer worldwide. HCC is characterized by deregulation of multiple genes and signalling pathways. These genetic effects can involve both protein coding genes as well as non-coding RNA genes. Long non-coding RNAs (lncRNAs) are transcripts longer than 200 nt, constituting a subpopulation of ncRNAs. Their biological effects are not well understood compared to small non-coding RNA (microRNAs), but they have been recently recognized to exert a crucial role in the regulation of gene expression and modulation of signalling pathways. Notably, several studies indicated that lncRNAs contribute to the pathogenesis and progression of HCC. Investigating the molecular mechanisms underlying lncRNAs expression opens potential applications in diagnosis and treatment of liver disease. This editorial provides three examples (MALAT-1 metastasis associated lung adenocarcinoma transcript, HULC highly upregulated in liver cancer and HOTAIR HOX transcript antisense intergenic RNA) of well-known lncRNAs upregulated in HCC, whose mechanisms of action are known, and for which therapeutic applications are delineated. Targeting of lncRNAs using several approaches (siRNA-mediated silencing or changing their secondary structure) offers new possibility to treat HCC.

    One hundred and forty years ago, Armand Trousseau described phlegmasia alba dolens as a sign of internal malignancy. Nowadays, it is commonly believed that the presence malignant tumaor increases the risk of venous thromboembolism (i.e deep vein thrombosis and pulmonary embolism) However, cancer is usually associated with other factors such as old age, extensive surgery,immobility, etc., which may predispose to thromboembolism. The majority of thrombotic events occur in the venous system; the incidence of arterial thrombosis is much lower.Recurrent thromboembolism in cancer patients frequently and diminishes the quality of life of the patients.Furthermore, if the thromboembolism is massive, destipte of early and aggressive treatment, it may result in death. In this article, we review thromboembolic complications in cancer patients.

    A novel cantilever array-based bio-sensor was batch-fabricated with IC compatible MEMS technology for precise liver cancer bio-marker detection. A micro-cavity was designed in the free end of the cantilever for local antibody-immobilization, thus the adsorption of the cancer biomarker takes place only in the local region of the cantilever instead of the whole lever, and the effect of adsorption-induced k variation can be dramatically reduced. These structural features offer several advantages: high sensitivity, high throughput, high mass detection accuracy, and a portable system. In addition, an analytical model has been established to eliminate the effect of the adsorption-induced lever stiffness change and has been applied to the precise mass detection of the cancer biomarker AFP; the experimentally detected AFP antigen mass by the sensor (7.6 pg/mL) is quite close to the calculated one (5.5 pg/mL), two orders of magnitude better than those of the fully antibody-immobilized cantilever sensor. These approaches can promote real applications of the cantilever sensors in cancer diagnosis.

    Abstract The overexpression of tissue factor (TF) observed in numerous cancer cells and clinical samples of human cancers makes TF an ideal target for cancer therapy. The purpose of this study is to develop a TF-targeting energized fusion protein hlFVII-LDP-AE, which is composed of a human Factor VII light chain (hlFVII) as the targeting domain conjugated to the cytotoxic antibiotic lidamycin (LDM, LDP-AE) as the effector domain. The potential efficacy of hlFVII-LDP-AE for cancer therapy was tested in vitro by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) and colony formation assays and in vivo with a BALB/c nude mouse xenograft model of human liver cancer line HepG2. The inhibitory concentration (IC50) value of hlFVII-LDP-AE varied from 0.15 to 0.64 nM for the various human tumor lines. hlFVII-LDP-AE showed a tumor growth inhibition rate of 90.6% at the dose of 0.6 mg/kg in in vivo animal experiments. The mechanism through which hlFVII-LDP-AE inhibits tumor growth also was determined by Hoechst 33342 staining and Tdt-mediated dUTP nick-end labeling (TUNEL) assay. hlFVII-LDP-AE causes tumor cell death through inducing chromatin condensation and cleavage of genomic DNA. These findings suggest that the hlFVII-LDP-AE protocol is efficacious and tolerated in the mouse model of human liver cancer HepG2 and has clinical applicability for treating cancer patients.

    The liver acts as a hub for metabolic reactions to keep a homeostatic balance during development and growth. The process of liver cancer development, although poorly understood, is related to different etiologic factors like toxins, alcohol, or viral infection. At the molecular level, liver cancer is characterized by a disruption of cell cycle regulation through many molecular mechanisms. In this review, we focus on the mechanisms underlying the lack of regulation of the cell cycle during liver cancer, focusing mainly on hepatocellular carcinoma (HCC). We also provide a brief summary of novel therapies connected to cell cycle regulation. PMID:24419005

    Background/Aims Deficiencies of 25-hydroxyvitamin D (25(OH)D) are prevalent in patients with chronic liver disease (CLD). Liver fibrosis is the main determinant of CLD prognosis. The present study was performed to evaluate the correlation between 25(OH)D levels and liver fibrosis as assessed by transient elastography (TE) in patients with compensated CLD. Methods Serum 25(OH)D levels and liver stiffness were determined in a total of 207 patients who were subjected to the following exclusion criteria: patients with decompensated CLD; patients who had malignancies; patients who were taking medications; and patients who were pregnant. Results The most common etiology was chronic hepatitis B (53.1%). Advanced liver fibrosis (defined by TE [≥9.5 kPa]) was present in 75 patients (36.2%). There was a significant correlation between 25(OH)D deficiency and liver stiffness. Based on the multivariate analysis, the following factors were independently associated with advanced liver fibrosis: 25(OH)D deficiency (odds ratio [OR], 3.46; p=0.004), diabetes mellitus (OR, 3.04; p=0.041), and fibrosis-4 index (OR, 2.01; p<0.001). Conclusions Patients with compensated CLD exhibit a close correlation between vitamin D level and liver stiffness as assessed by TE. Vitamin D deficiency was independently associated with advanced liver fibrosis. PMID:27114415

    There is a known association between chemotherapy and radiotherapy for treatment of cancer patients and development or worsening of hypertension. The aim of this article is to review this association. A literature search was conducted for articles reporting this association on the databases PubMed, SciELO and LILACS between 1993 and 2013. There was a high coprevalence of hypertension and cancer, since both diseases share the same risk factors, such as sedentary lifestyle, obesity, smoking, unhealthy diet and alcohol abuse. The use of chemotherapy and adjuvant drugs effective in the treatment of cancer increased the survival rate of these patients and, consequently, increased the incidence of hypertension. We described the association between the use of angiogenesis inhibitors (bevacizumab, sorafenib and sunitinib), corticosteroids, erythropoietin and non-steroidal anti-inflammatory drugs with the development of hypertension. We also described the relationship between hypertension and carotid baroreceptor injury secondary to cervical radiotherapy. Morbidity and mortality increased in patients with cancer and hypertension without proper antihypertensive treatment. We concluded that there is need for early diagnosis, effective monitoring and treatment strategies for hypertension in cancer patients in order to reduce cardiovascular morbidity and mortality.

    Abstract Mycobacterium arupense is a slow-growing, nonchromogenic, acid-fast bacillus. Its clinical spectrum, epidemiology, and frequency of colonization versus true infection remain unknown. We evaluated the clinical significance of M arupense and positive cultures from cancer patients. We retrospectively reviewed records of all cancer patients treated at our institution between 2007 and 2014 to identify those who had positive cultures for M arupense. Mycobacterium arupense was identified by sequencing the 16S rRNA and hsp65 genes. A total of 53patients had positive cultures, 100% of which were isolated from respiratory specimens. Of these, 7 patients met the American Thoracic Society/Infectious Diseases Society of America criteria for a definitive diagnosis of M arupense infection, 14 cases were considered to be probable infections, and 29 cases were considered to be possible infections. Of the included patients, 13 received therapy for M arupense infection and 40 did not. The outcomes of treated and untreated patients did not differ significantly. No relapses of M arupense infection. In addition, there were no M arupense-related deaths in either group. In cancer patients, M arupense appears to be mostly a commensal organism rather than a pathogen. Patients who did or did not receive treatment had similar outcomes. Validation of these findings in a larger prospective trial is warranted. PMID:27057825

    Cancer patients are regularly affected by malnutrition which often leads to a worsened quality of life and activity in daily living, more side effects and complications during anticancer treatment and shorter survival times. The early diagnosis and treatment of malnutrition are therefore relevant components of oncological treatment. The assessment of the nutritional status and determination of the body-mass-index should be done in every patient with cancer. The clinical examination delivers important findings and indications for malnutrition. Bioimpedance analysis can deliver additional objective information. The treatment of malnutrition should start early and follows a step-wise escalation reaching from nutritional counseling to enteral nutritional support to parenteral nutrition.

    Background Tumor necrosis factor alpha (TNF) is able to kill cancer cells via receptor-mediated cell death requiring adenosine triphosphate (ATP). Clinical usage of TNF so far is largely limited by its profound hepatotoxicity. Recently, it was found in the murine system that specific protection of hepatocytes against TNF's detrimental effects can be achieved by fructose-mediated ATP depletion therein. Before employing this quite attractive selection principle in a first clinical trial, we here comprehensively investigated the interdependence between ATP depletion and TNF hepatotoxicity in both in vitro and ex vivo experiments based on usage of primary patient tissue materials. Methods Primary human hepatocytes, and both non-tumorous and tumorous patient-derived primary liver tissue slices were used to elucidate fructose-induced ATP depletion and TNF-induced cytotoxicity. Results PHH as well as tissue slices prepared from non-malignant human liver specimen undergoing a fructose-mediated ATP depletion were both demonstrated to be protected against TNF-induced cell death. In contrast, due to tumor-specific overexpression of hexokinase II, which imposes a profound bypass on hepatocytic-specific fructose catabolism, this was not the case for human tumorous liver tissues. Conclusion Normal human liver tissues can be protected transiently against TNF-induced cell death by systemic pretreatment with fructose used in non-toxic/physiologic concentrations. Selective TNF-targeting of primary and secondary tumors of the liver by transient and specific depletion of hepatocytic ATP opens up a new clinical avenue for the TNF-based treatment of liver cancers.

    Background Although liver transplantation has been widely practised, post-operative bacterial infection is still a frequent complication which contributed to an increased risk of fatality. There were studies on preoperative use of probiotics for liver transplant patients and acquired reduction in postoperative sepsis and wound infection, but the relevant clinical experience with pre- and probiotics is still limited. Objectives This study is to assess fibre and probiotic use aimed at preventing bacterial sepsis and wound complications in patients undergoing liver transplantation. Study methods There were a total of sixty-seven adult patients scheduled for liver transplantation were included in a public teaching hospital. From January to December 2011, 34 continuous patients following liver transplantation were put on fibre + probiotics. In retrospectively, from January to December 2010, 33 continuous patients were collected as a control group and they were only received fibre post operation. The incidence of bacterial infections was compared in patients receiving either fibre and lactobacillus or fibre only. Statistical analysis was performed using SPSS 15. The t test, fisher’s and chi- square test was used to compare discrete variables. Results In summary, in the analysis of 67 liver transplant recipients, 8.8% group A patients developed infections compared to 30.3% group B patients. The difference between groups A and B was statistically significant in both cases. In addition, the duration of antibiotic therapy was significantly shorter in the lactobacillus-group. Wound infection was the most frequent infections and enterococci the most frequently isolated bacteria. Fibre and lactobacilli were well tolerated in most cases. The operating time, amount of intra- and post-operatively transfused units of blood, fresh frozen plasma and albumin did not differ significantly between the groups.

    2016-01-01

    Hepatocellular carcinoma (HCC) is a common, increasingly prevalent malignancy. For all but the smallest lesions, surgical removal of cancer via resection or liver transplantation (LT) is considered the most feasible pathway to cure. Resection - even with favorable survival - is associated with a fairly high rate of recurrence, perhaps since most HCCs occur in the setting of cirrhosis. LT offers the advantage of removing not only the cancer but the diseased liver from which the cancer has arisen, and LT outperforms resection for survival with selected patients. Since time waiting for LT is time during which HCC can progress, loco-regional therapy (LRT) is widely employed by transplant centers. The purpose of LRT is either to bridge patients to LT by preventing progression and waitlist dropout, or to downstage patients who slightly exceed standard eligibility criteria initially but can fall within it after treatment. Transarterial chemoembolization and radiofrequency ablation have been the most widely utilized LRTs to date, with favorable efficacy and safety as a bridge to LT (and for the former, as a downstaging modality). The list of potentially effective LRTs has expanded in recent years, and includes transarterial chemoembolization with drug-eluting beads, radioembolization and novel forms of extracorporal therapy. Herein we appraise the various LRT modalities for HCC, and their potential roles in specific clinical scenarios in patients awaiting LT. PMID:27358775

    Polyamines, one of the most important kind of biomarkers in cancer research, were investigated in order to characterize different cancer types. An integrative approach which combined ultra-high performance liquid chromatography-tandem mass spectrometry detection and multiple statistical data processing strategies including outlier elimination, binary logistic regression analysis and cluster analysis had been developed to discover the characteristic biomarkers of lung and liver cancer. The concentrations of 14 polyamine metabolites in biosamples from lung (n = 50) and liver cancer patients (n = 50) were detected by a validated UHPLC-MS/MS method. Then the concentrations were converted into independent variables to characterize patients of lung and liver cancer by binary logic regression analysis. Significant independent variables were regarded as the potential biomarkers. Cluster analysis was engaged for further verifying. As a result, two values was discovered to identify lung and liver cancer, which were the product of the plasma concentration of putrescine and spermidine; and the ratio of the urine concentration of S-adenosyl-l-methionine and N-acetylspermidine. Results indicated that the established advanced method could be successfully applied to characterize lung and liver cancer, and may also enable a new way of discovering cancer biomarkers and characterizing other types of cancer.

    2015-01-01

    End-stage liver disease (ESLD) is a leading cause of morbidity and mortality amongst human immunodeficiency virus (HIV)-positive individuals. Chronic hepatitis B and hepatitis C virus (HCV) infection, drug-induced hepatotoxicity related to combined anti-retro-viral therapy, alcohol related liver disease and non-alcohol related fatty liver disease appear to be the leading causes. It is therefore, anticipated that more HIV-positive patients with ESLD will present as potential transplant candidates. HIV infection is no longer a contraindication to liver transplantation. Key transplantation outcomes such as rejection and infection rates as well as medium term graft and patient survival match those seen in the non-HIV infected patients in the absence of co-existing HCV infection. HIV disease does not seem to be negatively impacted by transplantation. However, HIV-HCV co-infection transplant outcomes remain suboptimal due to recurrence. In this article, we review the key challenges faced by this patient cohort in the pre- and post-transplant period. PMID:26604639

    Caring for liver transplant patients suffering from chronic hepatitis C virus (HCV) infection is a challenging task for transplant surgeons and primary physicians alike. HCV is the leading cause of liver transplantation in the USA and comes with a myriad of complications that increase morbidity and mortality. This review focuses on patient follow-up, spanning from before the liver transplant occurs to the patient’s long-term health. Pretransplant, both donor and recipient variables, must be carefully chosen to ensure optimal surgical success. Risk factors must be identified and HCV viral load must be reduced to a minimum. In addition to standard transplant complications, HCV patients suffer from additional problems, such as fibrosing cholestatic hepatitis and widespread viremia. Physicians must focus on the balance of immunosuppressive and antiviral medications, while considering possible side effects from these potent drugs. Over the years following surgery, physicians must identify any signs of failing liver health, as HCV-positive patients have an increased risk for cirrhosis and certain life-threatening malignancies.

    Patients with nonalcoholic fatty liver disease (NAFLD) often have dyslipidemia along with other features of metabolic syndrome such as obesity, diabetes mellitus, and hypertension. The dyslipidemia in NAFLD is characterized by increased serum triglycerides, increased small, dense low-density lipoprotein (LDL nontype A) particles, and low high-density lipoprotein (HDL) cholesterol. The pathogenesis of dyslipidemia in NAFLD is not well understood, but it is likely related to hepatic overproduction of the very low-density lipoprotein particles and dysregulated clearance of lipoproteins from the circulation. There is unequivocal evidence that cardiovascular disease is the most common cause of mortality in patients with NAFLD. Aggressive treatment of dyslipidemia plays a critical role in the overall management of patients with NAFLD. Statins are the first-line agents to treat high cholesterol and their dosage should be adjusted based on achieving therapeutic targets and tolerability. Although all statins appear to be effective in improving cholesterol levels in patients with NAFLD, there is more experience with atorvastatin in patients with NAFLD; furthermore, it is the only statin to date to show a reduced cardiovascular morbidity in patients with NAFLD. The risk for serious liver injury from statins is quite rare and patients with NAFLD are not at increased risk for statin hepatotoxicity. Omega-3 fatty acids are perhaps the first choice to treat hypertriglyceridemia because of their safety, tolerability, and efficacy in improving serum triglycerides, as well as their potential to improve liver disease.

    There is ongoing evidence that vitamin D is related to the pathophysiology of cirrhosis. Although the incidence of vitamin D deficiency in chronic liver diseases and cirrhosis is strongly documented, its pathogenic association with advanced liver fibrosis remains controversial. There is evidence of a significant relation of 25(OH)D levels with the degree of liver dysfunction, considering that an inverse correlation of 25(OH)D levels with both Child-Pugh score and Model for End-Stage Liver Disease has been reported. In addition, vitamin D deficiency has been shown to increase the risk for overall mortality and infections in patients with cirrhosis. Vitamin D deficiency has been also associated with advanced stages of hepatocellular carcinoma and poor prognosis. Finally, there are studies suggesting that patients with chronic hepatitis C and normal vitamin D levels have higher virological response to treatment. However, there are not enough studies conducted in cirrhotic-only populations. The association between vitamin D and cirrhosis demonstrates a great potential for clinical application. The relation between vitamin D deficiency and the degree of liver function, degree of fibrosis and infectious complications could support its use as a prognostic index and a diagnostic tool.

    Colon cancer is the second most common type of cancer in females and the third in males, worldwide. The most common sites of colon cancer metastasis are the regional lymph nodes, liver, lung, bone and brain. In this study, an extremely rare case of colon adenocarcinoma with extensive metastasis to the mediastinal lymph nodes without any other organ involvement is presented. A 44-year-old Caucasian male presented with abdominal pain, a change in bowel habits, melena and weight loss. Colonoscopy revealed a large friable, ulcerated, circumferential mass in the ascending colon. Biopsies were consistent with the diagnosis of invasive moderately differentiated adenocarcinoma. Subsequently, right colon resection was performed, and pathological analysis revealed moderately differentiated adenocarcinoma of the right colon with extensive regional lymph node involvement. Computed tomography (CT) scans of the chest, abdomen and pelvis were performed preoperatively as part of routine staging for colon cancer. No liver or lung pathology was identified; however, multiple pathologically enlarged mediastinal lymph nodes were observed. Endoscopic ultrasound with fine needle aspiration of the largest mediastinal lymph node, which measured 5.2×3.5 cm on CT scans, was performed. The pathology was again consistent with the diagnosis of metastatic colorectal primary adenocarcinoma. At present, no optimum treatment has been identified for metastatic colon cancer to the mediastinal lymph nodes. The patient in the current case received chemotherapy with folinic acid, fluorouracil and oxaliplatin (FOLFOX), as well as with bevacizumab. Initial follow-up CT scans of the chest revealed a positive response to treatment. Physicians, in particular, radiologists, must consider the mediastinum during the first evaluation and further follow-up of patients with colorectal carcinoma even in the absence of metastasis.

    Simpson-Golabi-Behmel syndrome type 1 (SGBS1) -OMIM 312870- is a rare X-linked inherited overgrowth syndrome caused by a loss of function mutation in the GPC3 gene. Affected patients present a variable phenotype with pre- and post-natal macrosomia, distinctive facial dysmorphism, organomegaly, and multiple congenital anomalies. Intellectual disability is not constant. About 10% of patients have an increased risk of developing embryonic tumors in early childhood. Only one case of biliary disease has been described so far. GPC3 is localized on Xq26. It encodes for glypican 3, a heparan sulfate proteoglycan, which among its different known roles, negatively regulates liver regeneration and hepatocyte proliferation. This report concerns a male with a SGBS1, carrier of a GPC3 pathogenic mutation, and neonatal liver disease, who developed an early biliary cirrhosis. Together with the associated risk of cancer and developmental delay, liver transplantation was discussed and then successfully performed at the age of 19 months. A hypothesis on the role of GPC3 in the patient's liver disease is also proposed. PMID:24357529

    Clinical use of high-intensity focused ultrasound (HIFU) under ultrasound or MR guidance as a non-invasive method for treating tumors is rapidly increasing. Tens of thousands of patients have been treated for uterine fibroid, benign prostate hyperplasia, bone metastases, or prostate cancer. Despite the methods' clinical potential, the liver is a particularly challenging organ for HIFU treatment due to the combined effect of respiratory-induced liver motion, partial blocking by the rib cage, and high perfusion/flow. Several technical and clinical solutions have been developed by various groups during the past 15 years to compensate for these problems. A review of current unmet clinical needs is given here, as well as a consensus from a panel of experts about technical and clinical requirements for upcoming pilot and pivotal studies in order to accelerate the development and adoption of focused ultrasound for the treatment of primary and secondary liver cancer.

    The optimal antiretroviral therapy (ART) regimen for human immunodeficiency virus (HIV)–infected patients with cancer remains unknown, as clinical trials are lacking and published data are insufficient to guide recommendations. When concomitant use of chemotherapy and ART is anticipated, overlap of toxic effects and drug–drug interactions between chemotherapy and ART may alter the optimal choice of ART. Prospective studies are urgently needed to further define the toxic effects of combined chemotherapy and ART in HIV-positive cancer patients. Such studies should aid the development of guidelines for treatment of this population. For now, clinicians should individualize decisions regarding treatment of HIV according to clinical and laboratory findings, cancer treatment plan (chemotherapy, radiotherapy, or surgery), liver or renal disease, potential adverse drug effects (eg, rash, gastrointestinal intolerance, bone marrow suppression), and patient preference. This review focuses on what infectious disease specialists need to know to select the most appropriate ART regimens for patients receiving chemotherapy. PMID:24642555

    Background & Aims The cancer stem cells (CSCs) have important therapeutic implications for multi-resistant cancers including hepatocellular carcinoma (HCC). Among the key pathways frequently activated in liver CSCs is NF-kB signaling. Methods We evaluated the CSCs-depleting potential of NF-kB inhibition in liver cancer achieved by the IKK inhibitor curcumin, RNAi and specific peptide SN50. The effects on CSCs were assessed by analysis of Side Population (SP), sphere formation and tumorigenicity. Molecular changes were determined by RT-qPCR, global gene expression microarray, EMSA, and Western blotting. Results HCC cell lines exposed to curcumin exhibited differential responses to curcumin and were classified as sensitive and resistant. In sensitive lines, curcumin-mediated induction of cell death was directly related to the extent of NF-kB inhibition. The treatment also led to a selective CSC-depletion as evidenced by a reduced SP size, decreased sphere formation, down-regulation of CSC markers and suppressed tumorigenicity. Similarly, NF-kB inhibition by SN50 and siRNA against p65 suppressed tumor cell growth. In contrast, curcumin-resistant cells displayed a paradoxical increase in proliferation and expression of CSC markers. Mechanistically, an important component of the CSC-depleting activity of curcumin could be attributed to a NF-kB-mediated HDAC inhibition. Co-administration of the class I/II HDAC inhibitor trichostatine sensitized resistant cells to curcumin. Further, integration of a predictive signature of curcumin sensitivity with human HCC database indicated that HCCs with poor prognosis and progenitor features are most likely to benefit from NF-kB inhibition. Conclusions These results demonstrate that blocking NF-kB can specifically target CSC populations and suggest a potential for combined inhibition of NF-kB and HDAC signaling for treatment of liver cancer patients with poor prognosis.

    A 68-year-old Caucasian man with hepatitis C virus-related cirrhosis was admitted to our Unit in February 2010 for a diagnostic evaluation of three centimetric hypoechoic focal liver lesions detected by regular surveillance ultrasound. The subsequent computer tomography (CT) led to a diagnosis of unifocal hepatocellular carcinoma (HCC) in VI hepatic segment, defined the other two nodules in the VI and VII segment as suspected metastases, and showed a luminal narrowing with marked segmental circumferential thickening of the hepatic flexure of the colon. Colonoscopy detected an ulcerated, bleeding and stricturing lesion at the hepatic flexure, which was subsequently defined as adenocarcinoma with a moderate degree of differentiation at histological examination. Finally, ultrasound-guided liver biopsy of the three focal liver lesions confirmed the diagnosis of HCC for the nodule in the VI segment, and characterized the other two lesions as metastases from colorectal cancer. The patient underwent laparotomic right hemicolectomy with removal of thirty-nine regional lymph nodes (three of them tested positive for metastasis at histological examination), and simultaneous laparotomic radio-frequency ablation of both nodule of HCC and metastases. The option of adjuvant chemotherapy was excluded because of the post-surgical onset of ascites. Abdomen CT and positron emission tomography/CT scans performed after 1, 6 and 12 mo highlighted a complete response to treatments without any radiotracer accumulation. After 18 mo, the patient died due to progressive liver failure. Our experience emphasizes the potential coexistence of two different neoplasms in a cirrhotic liver and the complexity in the proper diagnosis and management of the two tumours. PMID:24409337

    Hepatorenal syndrome (HRS) plays an important role in patients with liver cirrhosis on the wait list for liver transplantation (LT). The 1 and 5-year probability of developing HRS in cirrhotic with ascites is 20% and 40%, respectively. In this article, we reviewed current concepts in HRS pathophysiology, guidelines for HRS diagnosis, effective treatment options presently available, and controversies surrounding liver alone vs simultaneous liver kidney transplant (SLKT) in transplant candidates. Many treatment options including albumin, vasoconstrictors, renal replacement therapy, and eventual LT have remained a mainstay in the treatment of HRS. Unfortunately, even after aggressive measures such as terlipressin use, the rate of recovery is less than 50% of patients. Moreover, current SLKT guidelines include: (1) estimation of glomerular filtration rate of 30 mL/min or less for 4-8 wk; (2) proteinuria > 2 g/d; or (3) biopsy proven interstitial fibrosis or glomerulosclerosis. Even with these updated criteria there is a lack of consistency regarding long-term benefits for SLKT vs LT alone. Finally, in regards to kidney dysfunction in the post-transplant setting, an estimation of glomerular filtration rate < 60 mL/min per 1.73 m2 may be associated with an increased risk of patients having long-term end stage renal disease. HRS is common in patients with cirrhosis and those on liver transplant waitlist. Prompt identification and therapy initiation in transplant candidates with HRS may improve post-transplantation outcomes. Future studies identifying optimal vasoconstrictor regimens, alternative therapies, and factors predictive of response to therapy are needed. The appropriate use of SLKT in patients with HRS remains controversial and requires further evidence by the transplant community. PMID:27648152

    Background Liver cancer is a common malignant tumor with high mortality. Currently, effective medicines against liver cancer are still lacking. Paclitaxel is a wide-spectrum anti-tumor agent, while wilfortrine has been shown to have an inhibitory effect on the proliferation of liver cancer cells. This study thus investigated the potential effect of paclitaxel combined with wilfortrine on cultured liver cancer cells and related mechanisms, in order to provide evidence for pathogenesis and treatment of liver cancer. Material/Methods Liver cancer cell line HpeG2 was divided into control, paclitaxel, wilfortrine, and combined treatment groups. Cell proliferation was tested by MTT, while invasion was detected in Transwell chamber assay. Apoptotic protein Bcl-2 and Bax expression levels were further quantified using real-time PCR and Western blotting. Results Both of those 2 drugs can effectively inhibit cancer cell proliferation, depress invasion ability, increase Bcl-2 expression, and elevate Bax expression levels (p<0.05 in all cases). The combined therapy had better treatment efficacy compared to either of those drugs alone (p<0.05). Conclusions The combined treatment using wilfortrine and paclitaxel can inhibit proliferation and invasion of liver cancer cells via down-regulating Bcl-2 and up-regulating Bax, with better efficacy than single use of either drug.

    Early detection of hepatocellular carcinoma (HCC) has become easier with recent advances in imaging diagnosis, but the tumor is frequently unresectable due to underlying advanced liver cirrhosis. In this study, we evaluated the therapeutic effect of percutaneous ethanol injection therapy (PEIT) and transarterial chemoembolization therapy (TACE) for small liver cancers measuring 3 cm or less in diameter and discussed the treatment of choice for unresectable cases. The tumors were divided into two groups on the basis of size: 1.5 cm or less (group A) and 1.6-3 cm in diameter (group B). In group A, the estimated 1- and 3-year survival rates were both 82% for a total of 19 cases. The survival value determined for 10 patients treated with PEIT was slightly higher than that found for 9 patients treated with TACE. In group B, the overall 1-, 2-, and 3-year survival values for a total of 56 patients were estimated at 83%, 60%, and 35%, respectively. The survival rates for 41 patients treated with TACE were 82%, 53%, and 28% at 1, 2, and 3 years, respectively. PEIT was performed on only 6 patients, whose survival rate was equivalent to that of a surgical resection group. The 1-, 2-, and 3-year survival rates for 9 patients who underwent surgical resection were estimated to be 100%, 85%, and 68%, respectively. Based on these results, PEIT seems to be the treatment of first choice for patients with small liver cancers measuring less than 1.5 cm in diameter if the tumor is thought to be unresectable because of associated severe liver cirrhosis. On the other hand, tumors measuring 1.6-3 cm in diameter must first be treated with TACE using a long-acting Lipiodol-carcinostatic suspension, even if resectable. In addition to the tumor size, dynamic CT is also useful for prospective decision of the therapeutic strategy. If the mass is demonstrated to be a hypervascular lesion by dynamic CT, TACE must be selected as the treatment of first choice, even for small lesions measuring 1

    AIM To evaluate risk of recidivism on a case-by-case basis. METHODS From our center’s liver transplant program, we selected patients with alcoholic liver disease who were listed for transplant based on Ohio Solid Organ Transplantation Consortium (OSOTC) exception criteria. They were considered to have either a low or medium risk of recidivism, and had at least one or three or more months of abstinence, respectively. They were matched based on gender, age, and Model for End-Stage Liver Disease (MELD) score to controls with alcohol-induced cirrhosis from Organ Procurement and Transplant Network data. RESULTS Thirty six patients with alcoholic liver disease were approved for listing based on OSOTC exception criteria and were matched to 72 controls. Nineteen patients (53%) with a median [Inter-quartile range (IQR)] MELD score of 24 (13) received transplant and were followed for a median of 3.4 years. They were matched to 38 controls with a median (IQR) MELD score of 25 (9). At one and five years, cumulative survival rates (± standard error) were 90% ± 7% and 92% ± 5% and 73% ± 12% and 77% ± 8% in patients and controls, respectively (Log-rank test, P = 0.837). Four (21%) patients resumed drinking by last follow-up visit. CONCLUSION Compared to traditional criteria for assessment of risk of recidivism, a careful selection process with more flexibility to evaluate eligibility on a case-by-case basis can lead to similar survival rates after transplantation.

    Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic non-viral liver disease. YKL-40, chitinase-like protein expressed in multiple tissues including liver, is involved in cell proliferation, inflammation and remodeling of the extracellular matrix. The aim of this study was to assess whether serum YKL-40 levels are associated with liver fibrosis in NAFLD patients. Serum YKL-40 levels were quantified in 111 NAFLD patients and 23 HCC patients with NAFLD. To identify the source of YKL-40, immunofluorescence staining of liver specimens from NAFLD patients was performed. Serum YKL-40 levels in NAFLD patients increased in accordance with the progression of liver fibrosis. Multivariate analysis revealed that YKL-40 was one of the independent factors significantly associated with severe fibrosis (F3-4). We established a new predictive model for fibrosis of NAFLD, using logistic regression analysis: YKL-40 based fibrosis score = −0.0545 + type IV collagen 7s * 0.3456 + YKL-40 * 0.0024. Serum YKL-40 levels of HCC patients with non-cirrhotic NAFLD were significantly higher than those without HCC. Immunofluorescence staining showed that YKL-40 was expressed by macrophages in liver tissue of NAFLD patients. In conclusion, macrophage-derived YKL-40 is a feasible biomarker of liver fibrosis in NAFLD patients. PMID:27739482

    Deregulation of the epigenome component affects multiple pathways in the cancer phenotype since the epigenome acts at the pinnacle of the hierarchy of gene expression. Pioneering work over the past decades has highlighted that targeting enzymes or proteins involved in the epigenetic regulation is a valuable approach to cancer therapy. Very recent results demonstrated that inhibiting the epigenetic reader BRD4 has notable efficacy in diverse cancer types. We investigated the potential of BRD4 as a therapeutic target in liver malignancy. BRD4 was overexpressed in three different large cohort of hepatocellular carcinoma (HCC) patients as well as in liver cancer cell lines. BRD4 inhibition by JQ1 induced anti-tumorigenic effects including cell cycle arrest, cellular senescence, reduced wound healing capacity and soft agar colony formation in liver cancer cell lines. Notably, BRD4 inhibition caused MYC-independent large-scale gene expression changes in liver cancer cells. Serial gene expression analyses with SK-Hep1 liver cancer cells treated with JQ1 to delineate the key player of BRD4 inhibition identified E2F2 as the first line of downstream direct target of BRD4. Further experiments including chromatin immunoprecipitation (ChIP) assay and loss of function study confirmed E2F2 as key player of BRD4 inhibition. Overexpressed E2F2 is a crucial center of cell cycle regulation and high expression of E2F2 is significantly associated with poor prognosis of HCC patients. Our findings reveal BRD4-E2F2-cell cycle regulation as a novel molecular circuit in liver cancer and provide a therapeutic strategy and innovative insights for liver cancer therapies.

    Objective. The incidence/death rate of hepatocellular cancer (HCC) is increasing in America, and it is unclear if access to care contributes to this increase. Design/Patients. 575 HCC cases were reviewed for demographics, education, and tumor size. Main Outcome Measures. Endpoints to determine access to HCC care included whether an eligible patient underwent liver transplantation. Results. Transplant patients versus those not transplanted were younger (55.7 versus 61.8 yrs, P < 0.001), males (89.3% versus 74.4%, P = 0.013), and having completed high school (10.1% versus 1.2%, P = 0.016). There were differences in transplant by ethnicity, insurance, and occupation. Transplant patients with HCC had higher median income via census classification ($54,383 versus $49,383, P = 0.046) and self-reported income ($48,948 versus $38,800, P = 0.002). Differences in access may be related to exclusion criteria for liver transplant, as Pacific Islanders were more likely to have tumor size larger than 5 cm compared to Whites and have BMI > 35 (20.7%) compared to Whites (6.4%) and Asians (4.7%). Conclusions. Ethnic differences in access to transplant are associated with socioeconomic status and factors that can disqualify patients (advanced disease/morbid obesity). Efforts to overcome educational barriers and screening for HCC could improve access to transplant. PMID:23304446

    Introduction Liver dysfunction associated with artificial nutrition in critically ill patients is a complication that seems to be frequent, but it has not been assessed previously in a large cohort of critically ill patients. Methods We conducted a prospective cohort study of incidence in 40 intensive care units. Different liver dysfunction patterns were defined: (a) cholestasis: alkaline phosphatase of more than 280 IU/l, gamma-glutamyl-transferase of more than 50 IU/l, or bilirubin of more than 1.2 mg/dl; (b) liver necrosis: aspartate aminotransferase of more than 40 IU/l or alanine aminotransferase of more than 42 IU/l, plus bilirubin of more than 1.2 mg/dl or international normalized ratio of more than 1.4; and (c) mixed pattern: alkaline phosphatase of more than 280 IU/l or gamma-glutamyl-transferase of more than 50 IU/l, plus aspartate aminotransferase of more than 40 IU/l or alanine aminotransferase of more than 42 IU/l. Results Seven hundred and twenty-five of 3,409 patients received artificial nutrition: 303 received total parenteral nutrition (TPN) and 422 received enteral nutrition (EN). Twenty-three percent of patients developed liver dysfunction: 30% in the TPN group and 18% in the EN group. The univariate analysis showed an association between liver dysfunction and TPN (p < 0.001), Multiple Organ Dysfunction Score on admission (p < 0.001), sepsis (p < 0.001), early use of artificial nutrition (p < 0.03), and malnutrition (p < 0.01). In the multivariate analysis, liver dysfunction was associated with TPN (p < 0.001), sepsis (p < 0.02), early use of artificial nutrition (p < 0.03), and calculated energy requirements of more than 25 kcal/kg per day (p < 0.05). Conclusion TPN, sepsis, and excessive calculated energy requirements appear as risk factors for developing liver dysfunction. Septic critically ill patients should not be fed with excessive caloric amounts, particularly when TPN is employed. Administering artificial nutrition in the first 24 hours

    Colorectal cancer (CRC) is one of the most common cancers in the world. In recent decades, drug therapy and surgery have not achieved satisfactory results in curing CRC. The identification of cancer stem cells (CSCs) has provided a possible mechanistic explanation of CRC growth and metastasis. Traditional chemotherapy targets rapidly dividing cells, and since the CSCs can escape these therapies and become circulating cells, CSCs may be responsible for cancer relapse and metastasis. A better understanding of the roles of CSCs in the pathogenesis of primary CRC and its metastasis, as well as how these CSCs are regulated at the molecular level, is of paramount importance. In this review, we summarize the current understanding of the role of colorectal CSCs in CRC liver metastasis, and provide some insights on the potential implication of colorectal CSCs to better design therapeutic regimens and prevent CRC metastasis.

    Purpose of review To review the experience to date and unique challenges associated with liver transplantation in hepatitis C virus (HCV)/HIV-coinfected patients. Recent findings The prevalence of cirrhosis and hepatocellular carcinoma is rising among HIV-infected individuals. With careful patient selection and in the absence of HCV infection, HIV-infected and HIV-uninfected liver transplant recipients have comparable posttransplant outcomes. However, in the presence of HCV infection, patient and graft survival are significantly poorer in HIV-infected recipients, who have a higher risk of aggressive HCV recurrence, acute rejection, sepsis, and multiorgan failure. Outcomes may be improved with careful recipient and donor selection and with the availability of new highly potent all-oral HCV direct acting antivirals (DAAs). Although all-oral DAAs have not been evaluated in HIV/HCV-coinfected transplant patients, HIV does not adversely impact treatment success in nontransplant populations. Therefore, there is great hope that HCV can be successful eradicated in HIV/HCV-coinfected transplant patients and will result in improved outcomes. Careful attention to drug–drug interactions with HIV antiretroviral agents, DAAs, and posttransplant immunosuppressants is required. Summary Liver transplant outcomes are poorer in HIV/HCV-coinfected recipients compared with those with HCV-monoinfection. The new HCV DAAs offer tremendous potential to improve outcomes in this challenging population. PMID:25944240

    AIM: To investigate the pathophysiology of the digestive tract in patients with liver cirrhosis. METHODS: In 42 cirrhotic patients and 20 control subjects, the following fecal proteins were measured by enzyme-linked immunosorbent assay: albumin (Alb), transferrin (Tf), and α1-antitrypsin (α1-AT) as a marker for intestinal protein loss, hemoglobin (Hb) for bleeding, PMN-elastase for intestinal inflammation, and secretory IgA for intestinal immunity. RESULTS: The fecal concentrations of Hb, Alb, Tf, α1-AT, an d PMN-elastase were increased in 13 (31%), 8 (19%), 10 (24%), 6 (14%), and 11 (26%) cases among 42 patients, respectively. Fecal concentration of secretory IgA was decreased in 7 (17%) of 42 patients. However, these fecal concentrations were not related to the severity or etiology of liver cirrhosis. The serum Alb level was significantly decreased in patients with intestinal protein loss compared to that in patients without intestinal protein loss. CONCLUSION: These findings suggest that: ① besides the well-known pathological conditions, such as bleeding and protein loss, intestinal inflammation and decreased intestinal immunity are found in cirrhotic patients; ② intestinal protein loss contributes to hypoalbuminemia in cirrhotic patients, and ③ intestinal inflammation should not be over looked in cirrhotic patients, since it may contribute to or cause intestinal protein loss and other various path ological conditions.

    We describe the case of an 87-year-old woman who presented to Tokyo Kousei Nenkin Hospital because of appetite loss and general fatigue. Multiple liver masses and Borrmann type 2 gastric tumor were detected. A clinical diagnosis of hepatocellular carcinoma and gastric cancer was made based on the patient's high levels of serum alpha-fetoprotein (AFP; 490 200 ng/mL) and protein induced by vitamin K absence or antagonist-II (PIVKA-II, 2284 mAU/mL). The patient's general condition worsened gradually and she died 42 days after admission. Autopsy revealed that the predominant histological structure of the gastric tumor was trabecular or sheet-like, although a tubular structure was also found. Venous invasion was prominent. Immunohistochemically, the tumor tissue was positive for AFP and a few tumor cells were positive for PIVKA-II. The histological appearance and immunohistochemical features of the hepatic tumors resembled that of the gastric tumor. This case was pathologically diagnosed as AFP- and PIVKA-II-producing gastric carcinoma with multiple liver metastases. When tumors are found in the stomach and liver and serum PIVKA-II level is abnormally high, the possibility of PIVKA-II-producing gastric cancer with liver metastasis should be considered, especially when hepatitis virus markers are negative and liver cirrhosis is not present.

  7. New concepts in liver cirrhosis: clinical significance of sarcopenia in cirrhotic patients.

    2013-06-01

    The natural history of cirrhotic patients is highly variable due to several factors including hepatic synthetic function, presence and degree of portal hypertension, the cause of cirrhosis, the possibility of resolution of the underlying damaging process, and the occurrence of liver cancer. Currently, D'Amico stage classification and Child-Pugh and Model for End-Stage Liver Disease (MELD) scores constitute the best tools to predict mortality in patients with cirrhosis; however, one of their main limitations is the lack of evaluation of the nutritional and functional status. Most widely recognized complications in cirrhotic patients include ascites, hepatic encephalopathy, variceal bleeding, kidney dysfunction, and hepatocellular carcinoma; however, sarcopenia or severe muscle wasting is one of the most common and frequently hidden complications which negatively impact survival, quality of life, and response to stressor, such as infection and surgery. In this review, we discuss the current accepted and new methods to evaluate prognosis in cirrhosis, and also analyze the current knowledge regarding incidence and clinical impact of malnutrition and sarcopenia in cirrhosis and their impact after liver transplantation. We also discuss existing and potential novel therapeutic strategies for malnutrition in cirrhosis, emphasizing the recognition of sarcopenia in cirrhosis in an effort to improve survival and reduced morbidity related to cirrhosis. Finally, we propose that future studies including sarcopenia with the MELD score may allow better prediction of mortality among cirrhotic patients waiting for liver transplantation; however, due to the worldwide shortage of organs for transplants, one of the vital clinical questions is the feasibility to treat sarcopenia in cirrhosis without the need of liver transplant.

    Liver cancer is one of the most common types of cancer, and hepatoma demonstrates a poor long-term prognosis. The present study reports that glaucocalyxin A (GLA), a natural product isolated from Rabdosia umbrosa, inhibits the growth of the liver cancer Focus and SMMC-7721 cell lines in a dose- and time-dependent manner. The present study revealed that GLA arrested the liver cancer cells at the G2/M stage of the cell cycle and led to decreased expression of caspase 3 and the cleavage of poly(adenosine diphosphate-ribose) polymerase. Overall, the present study demonstrated that GLA inhibits the growth of liver cancer cells by G2/M stage cell-cycle arrest and cell apoptosis. PMID:26893714

    Liver cancer is one of the most common and highly malignant cancers in the world. There are no effective therapeutic options if an early liver cancer diagnosis is not achieved. In this work, detection of HepG2 cells by label-free microcantilever array aptasensor was developed. The sensing microcantilevers were functionalized by HepG2 cells-specific aptamers. Meanwhile, to eliminate the interferences induced by the environment, the reference microcantilevers were modified with 6-mercapto-1-hexanol self-assembled monolayers. The aptasensor exhibits high specificity over not only human liver normal cells, but also other cancer cells of breast, bladder, and cervix tumors. The linear relation ranges from 1×10(3) to 1×10(5)cells/mL, with a detection limit of 300 cells/mL (S/N=3). Our work provides a simple method for detection of liver cancer cells with advantages in terms of simplicity and stability.

    We investigated the combined effect of ethanol and high-intensity focused ultrasound (HIFU), first, on heating and cavitation bubble activity in tissue-mimicking phantoms and porcine liver tissues and, second, on the viability of HepG2 liver cancer cells. Phantoms or porcine tissues were injected with ethanol and then subjected to HIFU at acoustic power ranging from 1.2 to 20.5 W (HIFU levels 1-7). Cavitation events and the temperature around the focal zone were measured with a passive cavitation detector and embedded type K thermocouples, respectively. HepG2 cells were subjected to 4% ethanol solution in growth medium (v/v) just before the cells were exposed to HIFU at 2.7, 8.7 or 12.0 W for 30 s. Cell viability was measured 2, 24 and 72 h post-treatment. The results indicate that ethanol and HIFU have a synergistic effect on liver cancer ablation as manifested by greater temperature rise and lesion volume in liver tissues and reduced viability of liver cancer cells. This effect is likely caused by reduction of the cavitation threshold in the presence of ethanol and the increased rate of ethanol diffusion through the cell membrane caused by HIFU-induced streaming, sonoporation and heating.

    This study aimed to assess the efficacy and safety of bevacizumab plus preoperative chemotherapy as first-line treatment for liver-only metastatic colorectal cancer in Chinese patients compared with those of preoperative chemotherapy alone.Patients with histologically confirmed liver-only metastatic colorectal cancer were sequentially reviewed, and received either preoperative chemotherapy plus bevacizumab (bevacizumab group, n = 32) or preoperative chemotherapy alone (chemotherapy group, n = 57). Progression-free survival, response rate, liver resection rate, conversion rate, and safety were analyzed.With median follow-up of 28.7 months, progression-free survival was 10.9 months (95% confidence interval: 8.7-13.1 months) in bevacizumab group and 9.9 months (95% confidence interval: 6.8-13.1 months) in chemotherapy group (P = 0.472). Response rates were 59.4% in bevacizumab group and 38.6% in chemotherapy group (P = 0.059). Overall liver resection (R0, R1, and R2) rate was 68.8% in bevacizumab group and 54.4% in chemotherapy group (P = 0.185). Conversion rate was 51.9% in bevacizumab group and 40.4% in chemotherapy group (P = 0.341). No postoperative complication was observed in all patients.Bevacizumab plus preoperative chemotherapy as first-line treatment for liver-only metastatic colorectal cancer tends to achieve better clinical benefit with controllable safety in Chinese patients.

    Non-alcoholic fatty liver disease (NAFLD) is a common cause of chronic non-viral liver disease. Activation of macrophages and hepatic stellate cells is a critical step that promotes liver fibrosis. We aimed to explore the feasibility of interleukin-34 (IL-34), a key regulator of macrophages, as a fibrosis marker in patients with NAFLD. We enrolled 197 liver biopsy-proven NAFLD patients. We evaluated the serum levels of IL-34, macrophage-colony stimulating factor (M-CSF), soluble CD163 (sCD163), 40 cytokines/chemokines, hyaluronic acid, type IV collagen 7s, and clinically-approved fibrosis scores. IL-34 increased with the progression of fibrosis and was an independent marker for liver fibrosis. Immunostaining experiments, using resected liver specimens from NAFLD patients, revealed that IL-34 was mainly expressed on liver fibroblasts. IL-34 based fibrosis score (0.0387*IL-34 (pg/ml) + 0.3623*type IV collagen 7s (ng/ml) + 0.0184*age (year)–1.1850) was a practical predictive model of liver fibrosis. Using receiver-operating characteristic analyses, the area under the curve, sensitivity, and specificity of IL-34 based fibrosis score were superior or comparable to the other fibrosis biomarkers and scores. In conclusion, the IL-34 based fibrosis score, including serum IL-34, type IV collagen 7s and age, is a feasible diagnostic marker of liver fibrosis in NAFLD patients. PMID:27363523

    We report a case of radical resection of rectal cancer with multiple liver and lung metastases after preoperative chemotherapy. A 54-year-old woman presented with abdominal pain and loss of body weight due to rectal cancer with multiple liver and lung metastases. Therefore, the patient received 14 courses of bevacizumab+mFOLFOX6, and 7 courses of panitumumab+FOLFIRI. After the chemotherapy, the size of the distant metastases reduced by 62% on computed tomography, according to RECIST. Due to the reduction in size, a conversion surgery was attempted. First, an abdominal operation with laparoscopy was performed, and 2 months later an operation to resect the lung metastases via thoracoscopy was performed. Currently, 3 months after surgery, the patient is alive, without recurrence.

    The role of nuclear receptor PXR in detoxification and clearance of xenobiotics and endobiotics is well-established. However, its projected role in hepatic cancer is rather illusive where its expression is reported altered in different cancers depending on the tissue-type and microenvironment. The expression of PXR, its target genes and their biological or clinical significance have not been examined in hepatic cancer. In the present study, by generating DEN-induced hepatic cancer in mice, we report that the expression of PXR and its target genes CYP3A11 and GSTa2 are down-regulated implying impairment of hepatic detoxification capacity. A higher state of inflammation was observed in liver cancer tissues as evident from upregulation of inflammatory cytokines IL-6 and TNF-α along with NF-κB and STAT3. Our data in mouse model suggested a negative correlation between down-regulation of PXR and its target genes with that of higher expression of inflammatory proteins (like IL-6, TNF-α, NF-κB). In conjunction, our findings with relevant cell culture based assays showed that higher expression of PXR is involved in reduction of tumorigenic potential in hepatic cancer. Overall, the findings suggest that inflammation influences the expression of hepatic proteins important in drug metabolism while higher PXR level reduces tumorigenic potential in hepatic cancer.

    Ionizing radiation used in treating the head and neck area produces oral side effects such as mucositis, salivary changes, trismus and radiation caries. Sequelae of cancer chemotherapy often include oral stomatitis, myelosuppression and immunosuppression. Infections of dental origin in compromised patients are potentially lethal. Specific programs to eliminate dental pathology before radiation and chemotherapy, and to maintain oral hygiene during and after therapy, will minimize these complications.

    A 62-year-old man was diagnosed with gastric cancer and underwent distal gastrectomy, and D1+b lymph node dissection. He was diagnosed postoperatively with T1b (sm2) N0M0, StageⅠA gastric adenocarcinoma and did not receive any adjuvant chemotherapy after surgery. One year and 6 months after gastrectomy, blood analysis indicated high levels of carcinoembryonic antigen (CEA 262.1 ng/mL) while abdominal computed tomography (CT) revealed multiple liver tumors (S7: 15 mm, S7/8: 20 mm). The patient was diagnosed with metachronous multiple liver metastases from gastric cancer. Chemotherapy, combined with molecular targeted therapy (S-1 plus cisplatin [CDDP] plus trastuzumab), was administered because of overexpression of the human epidermal growth factor receptor 2 (HER2) protein in the primary tumor as assessed by immunohistochemistry, the CEA levels decreased immediately after 2 cycles of the chemotherapy, and the liver metastases shrank markedly with no evidence of new lesions on abdominal CT. However, after treatment, Grade 3 neutropenia and diarrhea were observed. Chemotherapy was suspended and hepatic resection was performed. After hepatic resection, the liver tumors were histologically evaluated as Grade 2 metastatic gastric adenocarcinoma, and the HER2 expression of remnant carcinoma cells was established. The patient has been in good health and remained free of recurrences in the 2 years and 3 months after the liver resection. Surgery with preoperative chemotherapy (S-1 plus CDDP plus trastuzumab) can be an effective treatment for liver metastasis from HER2-positive gastric cancer. PMID:26805121

    Perampanel is one of the latest released antiepileptic drugs (AEDs). Early studies suggest no significant liver enzyme induction from this compound. We report on two patients with medically resistant epilepsy, who had perampanel added to their usual regimen. Both experienced a worsening of their epilepsy and presented in convulsive status epilepticus; concurrent antiepileptic drug levels (phenytoin, phenobarbital, rufinamide) were significantly decreased (<50%) in comparison with levels prior to perampanel introduction. Intravenous load and significant increase of maintenance dosages were needed to restore therapeutic drug levels. In one patient, further increase of perampanel resulted in a new drop of phenytoin level. This suggests that perampanel could, in some subjects, induce liver enzymes and interact with concomitant AEDs; monitoring levels of concomitant compounds could be useful. PMID:25227593

    A 66-year-old female with cryptogenic cirrhosis complicated by ascites, hepatic encephalopathy, variceal bleeding and malnutrition with MELD of 34 underwent orthotopic deceased donor liver transplantation performed with piggyback technique. Extensive eversion thromboendovenectomy was performed for a portal vein thrombus which resulted in an excellent portal vein flow. The liver graft was recirculated without any hemodynamic instability. Subsequently, the patient became hypotensive progressing to asystole. She was resuscitated and a transesophageal probe was inserted which revealed a mobile right atrial thrombus and an underfilled poorly contractile right ventricle. The patient was noted to be coagulopathic at the time. She became progressively more stable with a TEE showing complete resolution of the intracardiac thrombus. PMID:21160996

    Background: Treatment of patients with severe liver dysfunction including hyperbilirubinemia secondary to liver metastases of gastrointestinal (GI) cancer is challenging. Regimen of oxaliplatin and fluoropyrimidine (FP)/folinic acid (FA) ± a monoclonal antibody (moAb), represents a feasible option considering the pharmacokinetics. Clinical data on the respective dosage and tolerability are limited and no recommendations are available. Methods: Consecutive patients with severe hyperbilirubinemia [>2 × upper limit of the normal range (ULN) and >2.4 mg/dl] due to liver metastases of GI cancer without options for drainage receiving oxaliplatin, FP/FA ± moAb were analyzed. To collect further data a review of the literature was performed. Results: A total of 12 patients were identified between 2011 and 2015. At treatment start, median bilirubin level was 6.1 mg/dl (>5 × ULN, range 2.7–13.6). The majority of patients (n = 11) received dose-reduced regimen with oxaliplatin (60–76%) and FP/FA (0–77%), rapidly escalating to full dose regimen. During treatment, bilirubin levels dropped more than 50% within 8 weeks or normalized within 12 weeks in 6 patients (responders). Median overall survival was 5.75 months (range 1.0–16.0 months) but was significantly prolonged in responders compared to nonresponders [9.7 and 3.0 months, p = 0.026 (two-sided test); 95% confidence interval (CI): 1.10–10.22]. In addition, case reports or series comprising a further 26 patients could be identified. Based on the obtained data a treatment algorithm was developed. Conclusion: Treatment with oxaliplatin, FP/FA ± moAb is feasible and may derive relevant benefits in patients with severe liver dysfunction caused by GI cancer liver metastases without further options of drainage.

    The initial success of living donor liver transplantation (LDLT) in the United States has resulted in a growing interest in this procedure. The impact of LDLT on liver transplantation will depend in part on the proportion of patients considered medically suitable for LDLT and the identification of suitable donors. We report the outcome of our evaluation of the first 100 potential transplant recipients for LDLT at the University of Colorado Health Sciences Center (Denver, CO). All patients considered for LDLT had first been approved for conventional liver transplantation by the Liver Transplant Selection Committee and met the listing criteria of United Network for Organ Sharing status 1, 2A, or 2B. Once listed, those patients deemed suitable for LDLT were given the option to consider LDLT and approach potential donors. Donors were evaluated with a preliminary screening questionnaire, followed by formal evaluation. Of the 100 potential transplant recipients evaluated, 51 were initially rejected based on recipient characteristics that included imminent cadaveric transplantation (8 patients), refusal of evaluation (4 patients), lack of financial approval (6 patients), and medical, psychosocial, or surgical problems (33 patients). Of the remaining 49 patients, considered ideal candidates for LDLT, 24 patients were unable to identify a suitable donor for evaluation. Twenty-six donors were evaluated for the remaining 25 potential transplant recipients. Eleven donors were rejected: 9 donors for medical reasons and 2 donors who refused donation after being medically approved. The remaining 15 donor-recipient pairs underwent LDLT. Using our criteria for the selection of recipients and donors for LDLT gave the following results: (1) 51 of 100 potential transplant recipients (51%) were rejected for recipient issues, (2) only 15 of the remaining 49 potential transplant recipients (30%) were able to identify an acceptable donor, and (3) 15 of 100 potential living donor

    The number of patients developing liver failure; acute on chronic liver failure and acute liver failure continues to increase, along with the demand for donor livers for transplantation. As such there is a clinical need to develop effective extracorporeal devices to support patients with acute liver failure or acute-on-chronic liver failure to allow time for hepatocyte regeneration, and so avoiding the need for liver transplantation, or to bridge the patient to liver transplantation, and also potentially to provide symptomatic relief for patients with cirrhosis not suitable for transplantation. Currently devices can be divided into those designed to remove toxins, including plasma exchange, high permeability dialyzers and adsorption columns or membranes, coupled with replacement of plasma proteins; albumin dialysis systems; and bioartificial devices which may provide some of the biological functions of the liver. In the future we expect combinations of these devices in clinical practice, due to the developments in bioartificial scaffolds.

    Cytomegalovirus (CMV) is the most common viral infection in solid organ transplant recipients. Symptomatic infection usually presents with fever, pneumonia, colitis, or cytopenia. We describe a case of symptomatic CMV infection in a liver transplant recipient presenting with atypical symptoms of only persistent nausea and vomiting, in the absence of classical symptoms and signs; thus, highlighting the importance of high index of suspicion of CMV in immunocompromised patients, keeping in mind the high morbidity and mortality associated with this disease.

    A bloodless surgery was required in the case of simultaneous liver metastases of colon cancer, one of which invaded at the confluence of left hepatic vein and inferior vena cava. In order to assure the safety and curability, hepatic arterial infusion chemotherapy aiming to size reduction was preceded to synchronous liver resection for a 53-year-old Jehovah's witness male. After gaining the reduction of tumor, synchronous liver resection was safely performed under a hemodilutional autotransfusion. The patient has been alive for 6 years under the withdrawal from chemotherapy. PMID:22202427

    Purpose: To propose a new method to estimate lung mean dose (LMD) using technetium-99m labeled macroaggregated albumin ({sup 99m}Tc-MAA) single photon emission CT (SPECT)/CT for {sup 90}Yttrium radioembolization of liver tumors and to compare the LMD estimated using SPECT/CT with clinical estimates of LMD using planar gamma scintigraphy (PS). Methods and Materials: Images of 71 patients who had SPECT/CT and PS images of {sup 99m}Tc-MAA acquired before TheraSphere radioembolization of liver cancer were analyzed retrospectively. LMD was calculated from the PS-based lung shunt assuming a lung mass of 1 kg and 50 Gy per GBq of injected activity shunted to the lung. For the SPECT/CT-based estimate, the LMD was calculated with the activity concentration and lung volume derived from SPECT/CT. The effect of attenuation correction and the patient's breathing on the calculated LMD was studied with the SPECT/CT. With these effects correctly taken into account in a more rigorous fashion, we compared the LMD calculated with SPECT/CT with the LMD calculated with PS. Results: The mean dose to the central region of the lung leads to a more accurate estimate of LMD. Inclusion of the lung region around the diaphragm in the calculation leads to an overestimate of LMD due to the misregistration of the liver activity to the lung from the patient's breathing. LMD calculated based on PS is a poor predictor of the actual LMD. For the subpopulation with large lung shunt, the mean overestimation from the PS method for the lung shunt was 170%. Conclusions: A new method of calculating the LMD for TheraSphere and SIR-Spheres radioembolization of liver cancer based on {sup 99m}Tc-MAA SPECT/CT is presented. The new method provides a more accurate estimate of radiation risk to the lungs. For patients with a large lung shunt calculated from PS, a recalculation of LMD based on SPECT/CT is recommended.

    We reviewed records of all patients with an initial Fontan operation or revision from 1973 to 2012 at our institution (n = 1,138); 195 patients had postoperative liver data available. Cirrhosis was identified by histopathology or characteristic findings on imaging with an associated diagnosis of cirrhosis by a hepatologist. Of 195 patients with biopsy or imaging, 10-, 20-, and 30-year freedom from cirrhosis was 99%, 94%, and 57%, respectively. There were 40 of 195 patients (21%) diagnosed with cirrhosis (mean age at Fontan 10.7 ± 8 years). On multivariate analysis, hypoplastic left heart syndrome was associated with increased risk of cirrhosis (n = 2 of 16, p = 0.0133), whereas preoperative sinus rhythm was protective (p = 0.009). Survival after diagnosis of cirrhosis was 57% and 35%, at 1, and 5 years, respectively. The cause of death was known for 9 patients (5 multiorgan failure, 2 liver failure, and 2 heart failure). In conclusion, there is an incremental occurrence of cirrhosis after the Fontan, which should be considered when designing follow-up protocols for patients after Fontan operation. PMID:26704027

    Background The Gambia Hepatitis Intervention Study (GHIS) was designed as a randomised control trial of infant hepatitis B vaccination applied to public health policy, with the main goal of preventing primary liver cancer later in adult life in The Gambia. To that effect, the National Cancer Registry of The Gambia (NCR), a population-based cancer registry (PBCR), was established in 1986 to actively collect data on all cancer diagnosis nation-wide. We extracted 20-years (1990-2009) of data to assess for the first time, the evolution of the most common cancers, also describe and demonstrate the role of the PBCR in a hepatitis B and liver cancer prevention programme in this population. Methods and Findings We estimated Age-Standardised Incidence Rates (ASR (W)) of the most common cancers registered during the period by gender. The registration period was divided into four 5-year intervals and incidence rates were estimated for each interval. The most common cancers in males were liver, prostate, lung plus bronchus, non-Hodgkin lymphoma (NHL) and stomach, accounting for 60%, 5%, 4%, 5% and 3%, respectively. Similarly, cancers of the cervix uteri, liver, breast and NHL, were the most common in females, accounting for 33%, 24%, 11% and 4% of the female cancers, respectively. Conclusions Cancer incidence has remained relatively stable over time, but as shown elsewhere in sub-Saharan Africa the disease is a threat in The Gambia. The infection related cancers which are mostly preventable (HBV in men and HPV/HIV in women) were the most common. At the moment the data is not enough to detect an effect of hepatitis B vaccination on liver cancer incidence in The Gambia. However, we observed that monitoring case occurrence through PBCR is a key public health pre-requisite for rational planning and implementation of targeted interventions for improving the health of the population.

    Radio-frequency ablation (RFA), the most widely used minimally invasive ablative therapy of liver cancer, is challenged by a lack of patient-specific planning. In particular, the presence of blood vessels and time-varying thermal diffusivity makes the prediction of the extent of the ablated tissue difficult. This may result in incomplete treatments and increased risk of recurrence. We propose a new model of the physical mechanisms involved in RFA of abdominal tumors based on Lattice Boltzmann Method to predict the extent of ablation given the probe location and the biological parameters. Our method relies on patient images, from which level set representations of liver geometry, tumor shape and vessels are extracted. Then a computational model of heat diffusion, cellular necrosis and blood flow through vessels and liver is solved to estimate the extent of ablated tissue. After quantitative verifications against an analytical solution, we apply our framework to 5 patients datasets which include pre- and post-operative CT images, yielding promising correlation between predicted and actual ablation extent (mean point to mesh errors of 8.7 mm). Implemented on graphics processing units, our method may enable RFA planning in clinical settings as it leads to near real-time computation: 1 minute of ablation is simulated in 1.14 minutes, which is almost 60x faster than standard finite element method.

    Among the adult organs, liver is unique for its ability to regenerate. A concerted signaling cascade enables optimum initiation of the regeneration process following insults brought about by surgery or a toxicant. Additionally, there exists a cellular redundancy, whereby a transiently amplifying progenitor population appears and expands to ensure regeneration, when differentiated cells of the liver are unable to proliferate in both experimental and clinical scenarios. One such pathway of relevance in these phenomena is Wnt/β-catenin signaling, which is activated relatively early during regeneration mostly through post-translational modifications. Once activated, β-catenin signaling drives the expression of target genes that are critical for cell cycle progression and contribute to initiation of the regeneration process. The role and regulation of Wnt/β-catenin signaling is now documented in rats, mice, zebrafish and patients. More recently, a regenerative advantage of the livers in β-catenin overexpressing mice was reported, as was also the case after exogenous Wnt-1 delivery to the liver paving the way for assessing means to stimulate the pathway for therapeutics in liver failure. β-Catenin is also pertinent in hepatic oval cell activation and differentiation. However, aberrant activation of the Wnt/β-catenin signaling is reported in a significant subset of hepatocellular cancers (HCC). While many mechanisms of such activation have been reported, the most functional means of aberrant and sustained activation is through mutations in the β-catenin gene or in AXIN1/2, which encodes for a scaffolding protein critical for β-catenin degradation. Intriguingly, in experimental models hepatic overexpression of normal or mutant β-catenin is insufficient for tumorigenesis. In fact β-catenin loss promoted chemical carcinogenesis in the liver due to alternate mechanisms. Since most HCC occur in the backdrop of chronic hepatic injury, where hepatic regeneration is

    Liver cancer stem cells (CSCs) are resistant to conventional chemotherapy and radiation, which may destroy tumor masses, but not all liver CSCs contribute to tumor initiation, metastasis, and relapse. In the present study, we showed that liver CSCs with elevated Wnt/β-catenin signaling possess much greater self-renewal and clonogenic potential. We further documented that the increased clonogenic potential of liver CSCs is highly associated with changes in Wnt/β-catenin signaling and that Wnt/β-catenin signaling activity is positively correlated with CD133 expression and aldehyde dehydrogenase (ALDH) enzymatic activity. Notably, the small molecule inhibitor CWP232228, which antagonizes the binding of β-catenin to TCF in the nucleus, inhibits Wnt/β-catenin signaling and depletes CD133+/ALDH+ liver CSCs, thus ultimately diminishing the self-renewal capacity of CSCs and decreasing tumorigenicity in vitro and in vivo. Taken together, our findings suggest that CWP232228 acts as a candidate therapeutic agent for liver cancer by preferentially targeting liver CSCs. PMID:26967248

    The long-term prognosis after resection of hepatocellular carcinoma (HCC), which is one of the treatment options for early-stage HCC, remains unsatisfactory as a result of a high incidence of disease recurrence. Recent studies performed in murine models revealed a link between liver regeneration under chronic inflammation and hepatic tumorigenesis. Sorafenib is a potent drug for advanced HCC with multikinase inhibition activity. We propose that inhibition of signal transduction pathways which are activated during hepatectomy, using Sorafenib, will reduce accelerated tumorigenesis. To test this hypothesis, we studied the Mdr2-knockout (KO) mouse strain, a model of inflammation-associated cancer, which underwent partial hepatectomy (PHx) at three months of age, with or without Sorafenib. Here we show that Sorafenib treatment during PHx inhibited different signal transduction pathways at the multikinase levels, but did not result in increased morbidity or mortality. At the early stages after PHx, Sorafenib treatment had no effect on the course of proliferation, apoptosis and DNA repair in the regenerating liver, but resulted in decreased stellate cells activation and inflammatory response. Finally, we show that Sorafenib treatment during PHx at three months of age resulted in decreased fibrosis and tumor formation at 8.5 months. In conclusion our study indicates that short-term Sorafenib treatment during PHx is safe and effective in inhibiting inflammation-associated cancer, and is therefore a potential strategy for recurrence prevention in patients with early-stage HCC treated with PHx.

    Conventional transcatheter arterial chemoembolization and chemoembolization with drug-eluting beads are increasingly being performed interchangeably in many institutions throughout the world. As both therapies continue to being tested in many phase II and III studies and in combination with other therapies, especially targeted agents, for treatment of primary and metastatic liver cancer, it is imperative to review their current status and evaluate their impact on patient survival. This review critically assesses patient selection, indications, contraindications, techniques, materials, safety, and clinical outcomes of patients treated with conventional chemoembolization and chemoembolization with drug-eluting beads.

    Traditional Chinese medicine (TCM) syndrome, also known as TCM ZHENG or TCM pattern, is an integral and essential part of TCM theory that helps to guide the design of individualized treatments. A TCM syndrome, in essence, is a characteristic profile of all clinical manifestations in one patient that can be readily identified by a TCM practitioner. In this article, the authors reviewed the presentations of TCM syndromes in seven common malignancies (liver, lung, gastric, breast, colorectal, pancreatic and esophageal cancers), the objectivity and the standardization of TCM syndrome differentiation, the evaluation of TCM syndrome modeling in cancer research, and syndrome differentiation-guided TCM treatment of cancers. A better understanding of TCM syndrome theory, as well as its potential biological basis, may contribute greatly to the clinical TCM diagnosis and the treatment of cancer.

    Breast cancer is the third most common illness in the world and the most frequent malignant disease with women. Cytotoxic therapy is connected to significant psychiatric adverse effects, and the appearance of depressive symptoms is the most common. The main goal is determining the degree of depression with breast cancer patients in the oncology ward of the University Clinical Hospital in Niš and its connection to their marital status, age, level of education, economic status and the number of therapy cycles. This research is a prospective study. The statistical data analysis included measures of descriptive and analytical statistics. The presence of depressive symptoms of different intensity was showed in 76.00% of the interviewees in group I, and the second included 77.4%. The frequency distributions show that 27.084% interviewees from the first group showed signs of depressive symptoms, while the second included 25%. The intensity of these symptoms categorizes them into the group of moderate to significantly expressed depressive states, so they require therapeutic treatment. Depression is significantly more often recorded with cancer patients receiving cytotoxic therapy; mild depression is the most common, followed by moderate and severe depression. PMID:27138829

    Objectives: The estimation of liver volume (LV) has been widely studied in normal liver, the density of which is considered to be equivalent to 1 kg/l. In cirrhosis, volumetric evaluation and its correlation to liver mass remain unclear. The aim of this study was to evaluate the accuracy of computed tomography (CT) scanning to assess LV in patients with cirrhosis. Methods: Liver volume was evaluated by CT (CTLV) and correlated to the explanted liver weight (LW) in 49 patients. Liver density (LD) and its association with clinical features were analysed. Commonly used formulae for estimating LV were also evaluated. The real density of cirrhotic liver was prospectively measured in explant specimens. Results: Wide variations between CTLV (in ml) and LW (in g) were found (range: 3–748). Cirrhotic livers in patients with hepatitis B virus infection presented significantly increased LD (P = 0.001) with lower CTLV (P = 0.005). Liver volume as measured by CT was also decreased in patients with Model for End-stage Liver Disease scores of >15 (P = 0.023). Formulae estimating LV correlated poorly with CTLV and LW. The density of cirrhotic liver measured prospectively in 15 patients was 1.1 kg/l. Conclusions: In cirrhotic liver, LV assessed by CT did not correspond to real LW. Liver density changed according to the aetiology and severity of liver disease. Commonly used formulae did not accurately assess LV. PMID:23679861

    Primary liver cancer encompasses both hepatocellular carcinoma (HCC) and cholangiocarcinoma (CC). The Notch signaling pathway, known to be important for the proper development of liver architecture, is also a potential driver of primary liver cancer. However, with four known Notch receptors and several Notch ligands, it is not clear which Notch pathway members play the predominant role in liver cancer. To address this question we utilized antibodies to specifically target Notch1, Notch2, Notch3 or Jag1 in a mouse model of primary liver cancer driven by AKT and NRas. We show that inhibition of Notch2 reduces tumor burden by eliminating highly malignant hepatocellular carcinoma- and cholangiocarcinoma-like tumors. Inhibition of the Notch ligand Jag 1 had a similar effect, consistent with Jag1 acting in cooperation with Notch2. This effect was specific to Notch2, as Notch3 inhibition did not decrease tumor burden. Unexpectedly, Notch1 inhibition altered the relative proportion of tumor types, reducing HCC-like tumors but dramatically increasing CC-like tumors. Finally, we show that Notch2 and Jag1 are expressed in, and Notch2 signaling is activated in, a subset of human HCC samples. Conclusions: These findings underscore the distinct roles of different Notch receptors in the liver and suggest that inhibition of Notch2 signaling represents a novel therapeutic option in the treatment of liver cancer.

    OBJECTIVES The long-term outcomes of patients with drug induced liver injury (DILI) are not well described. The aim of this study was to determine the frequency and severity of persistent liver biochemistry abnormalities in DILI patients followed over 2 years. METHODS Subjects with evidence of liver injury at 6 months after DILI onset were offered a month 12 and 24 study visit. RESULTS Amongst the 99 patients with definite, probable, or very likely DILI and available laboratory data at 12 months after DILI onset, 74 (75%) had persistent liver injury (persisters) defined as a serum AST or ALT > 1.5 × upper limit of normal (ULN) or an alkaline phosphatase > ULN, while 25 (25%) had resolved liver injury (resolvers). On multivariate analysis, month 12 persisters were significantly older (52.6 vs 43.7 years, p=0.01) and more likely to have a cholestatic lab profile at DILI onset (54% vs 20%, p < 0.01) than resolvers. The month 12 persisters also had significantly poorer SF-36 Physical summary scores at DILI onset and throughout follow-up compared to the resolvers (p < 0.01). Amongst the 17 subjects with a liver biopsy obtained at a median of 387 days after DILI onset, 9 had chronic cholestasis, 3 had steatohepatitis, and 3 had chronic hepatitis. CONCLUSION 75% of subjects with liver injury at 6 months after DILI onset have laboratory evidence of persistent liver injury during prolonged follow-up. Higher serum alkaline phosphatase levels at presentation and older patient age were independent predictors of persistent liver injury. Subjects with persistent liver injury at 12 months after DILI onset should be carefully monitored and assessed for liver disease progression. PMID:26346867

    The role of ultrasonography, computed tomography (CT), and radioisotopic scanning in the staging of bilharzial bladder cancer has not been reported previously. Forty patients with invasive bladder cancer seen at the King Faisal Specialist Hospital and Research Centre between January 1978 and June 1981 underwent complete preoperative workup for staging of their tumors prior to radical cystectomy. The preoperative radiologic investigations included excretory urography (IVP), ultrasonography (US), CT of the pelvis, and liver and bone scans. The results of these investigations were compared with the operative and pathologic staging. Ninety-three percent of the patients with bilharzial cancer had evidence of ureteric obstruction on IVP compared with 22% of the nonbilharzial cancer patients. The presence of ureteric obstruction in these patients did not correlate with the stage of the disease with 83% of the patients with superficial tumors (T1 and T2) having hydroureteronephrosis. Ultrasonography and CT had an 83% accuracy in the staging of superficial tumors. Stage T3 tumors were understaged in 14% of the cases. Ultrasonography did not differentiate Stages T3 and T4 tumors while CT scan differentiated these two stages in 57% of the cases. Bone scan failed to reveal evidence of metastatic disease in any of the bilharzial cancer patients. Liver scan was suspicious for liver metastases in two patients with bilharzial cancers in whom open liver biopsy revealed only hepatic bilharziasis. Of all the radiographic studies, US or preferably CT scan seem to be of some value in the staging of bilharzial tumors localized to the bladder. Bone and liver scans are probably of no cost effective benefit.

    Background Some patients with cancer experience multiple pre-diagnostic consultations in primary care, leading to longer time intervals to specialist investigations and diagnosis. Patients with rarer cancers are thought to be at higher risk of such events, but concrete evidence of this is lacking. Aim To examine the frequency and predictors of repeat consultations with GPs in patients with rarer cancers. Design and setting Patient-reported data on pre-referral consultations from three English national surveys of patients with cancer (2010, 2013, and 2014), pooled to maximise the sample size of rarer cancers. Method The authors examined the frequency and crude and adjusted odds ratios for ≥3 (versus 1–2) pre-referral consultations by age, sex, ethnicity, level of deprivation, and cancer diagnosis (38 diagnosis groups, including 12 rarer cancers without prior relevant evidence). Results Among 7838 patients with 12 rarer cancers, crude proportions of patients with ≥3 pre-referral consultations ranged from >30.0% to 60.0% for patients with small intestine, bone sarcoma, liver, gallbladder, cancer of unknown primary, soft-tissue sarcoma, and ureteric cancer. The range was 15.0–30.0% for patients with oropharyngeal, anal, parotid, penile, and oral cancer. The overall proportion of responders with any cancer who had ≥3 consultations was 23.4%. Multivariable logistic regression indicated concordant patterns, with strong evidence for variation between rarer cancers (P <0.001). Conclusion Patients with rarer cancers experience pre-referral consultations at frequencies suggestive of middle-to-high diagnostic difficulty. The findings can guide the development of new diagnostic interventions and ‘safety-netting’ approaches for symptomatic presentations encountered in patients with rarer cancers. PMID:26917657

    Primary liver cancer has a high incidence and high mortality rates, and currently the only viable option is surgery, although there are a number of difficulties related to this method. The aim of the present study was to investigate the potential advantages of the real-time contrast-enhanced ultrasonography (CEUS) for microwave ablation of primary liver cancer. One hundred patients with primary liver cancer were included in the study. The patients were divided into the ordinary ultrasonography and the CEUS groups. For the ordinary ultrasonography group, the ordinary ultrasonography-guided microwave ablation method was used, while microwave ablation under the guidance of CEUS was conducted for the CEUS group. The size of lesions and clearness of the tumor boundary prior to surgery in the two groups were compared. Additionally, postoperative complications and the survival rate were monitored. Lesion boundary areas measured by CEUS were significantly larger than those measured with ordinary ultrasonography. The incidence rate of postoperative pain, fever, intra-abdominal hemorrhage and infection and other complications in the ordinary ultrasonography group were significantly higher than that in the CEUS group. The tumor recurrence rate in the CEUS group was significantly lower than that in the ordinary ultrasonography group. Seventy-two percent of patients in the CEUS group showed no progress, compared to 48% of in the ordinary ultrasonography group. The progress-free survival rate in the CEUS group after 6 months was significantly higher than that in the ordinary ultrasonography group. Disease-free survival time in the CEUS group was considerably longer than the control group. In conclusion, the guidance of real-time CEUS on the primary liver cancer microwave ablation treatment can achieve good intra-operative results. It offers a real-time guidance effect, improves survival time and reduces the incidence of complications.

    Increasing numbers of patients with non-alcoholic steatohepatitis (NASH) are referred for liver transplant (LT). Our objective was to characterize patients with NASH among referred LT candidates (from 1998 to 2008), and we compared demographics, etiology of liver disease, diabetes, hypertension, smoking, obesity, cardiac disease, cancer, laboratory data, model for end-stage liver disease (MELD), and outcomes between NASH and non-NASH patients. Patients with NASH (n = 71) were compared to other chronic liver disease (n = 472). Patients with NASH were older (58.7 vs. 52.5 yr, p < 0.0001), Asian (53.5% vs. 34.7%, p = 0.03) and women (50.7% vs. 32.1%, p = 0.003). Patients with NASH had more diabetes, hypertension, obesity, cardiac disease, and smoking history (p < 0.05). Patients with NASH were equally likely to have liver cancer, but more likely to have non-liver cancers (20.8% vs. 4.4%, p = 0.008). There was no difference in MELD, but patients with NASH had lower protime/international normalized ratio (1.14 vs. 1.27, p = 0.04) and higher creatinine (1.26 vs. 0.98 mg/dL, p = 0.0018). Patients with NASH were equally likely to undergo evaluation, listing, and transplantation compared to non-NASH patients. While all patients with chronic liver disease can have renal dysfunction because of hepatorenal syndrome, patients with NASH have more renal dysfunction, perhaps related to diabetes, hypertension, and cardiovascular disease. Transplant centers should consider this carefully in selection of candidates for LT. PMID:21958082

    Advanced liver disease is becoming more prevalent in the United States. This increase has been attributed largely to the growing epidemic of nonalcoholic fatty liver disease and an aging population infected with hepatitis C. Complications of cirrhosis are a major cause of hospital admissions and readmissions. It is important to target efforts for preventing rehospitalization toward patients with cirrhosis who are at the highest risk for readmission, such as those who have high Model for End-Stage Liver Disease scores, are at risk for fluid/electrolyte abnormalities or overt hepatic encephalopathy recurrence, and those who have comorbid conditions (e.g. diabetes). The heart failure management paradigm may provide valuable insights for managing patients with cirrhosis, given the extensive research on preventing hospital readmission and improving health care utilization in this subpopulation. As quality measures related to hospital readmissions for cirrhosis and its complications are adopted by the Centers for Medicare & Medicaid Services and private payers in the future, understanding drivers of hospital readmissions and health care utilization in this vulnerable population are key to improving quality measure performance.

    The carcinogenic effect of arsenic is well documented, but epidemiologic data on liver cancer were limited. To evaluate the dose-response relationship between arsenic in drinking water and mortality of liver cancer, we conducted a study in 138 villages in the southwest coast area of Taiwan. We assessed arsenic levels in drinking water using data from a survey conducted by the government and reviewed death certificates from 1971 to 1990 to identify liver cancer cases. Using village as the unit, we conducted multi-variate regression analyses and then performed post hoc analyses to validate the findings. During the 20-year period, 802 male and 301 female mortality cases of liver cancer were identified. After adjusting for age, arsenic levels above 0.64 mg/L were associated with an increase in the liver cancer mortality in both genders, but no significant effect was observed for lower exposure categories. Post hoc analyses and a review of literature supported these findings. We concluded that exposures to high arsenic levels in drinking water are associated with the occurrence of liver cancer, but such an effect is not prominent at exposure levels lower than 0.64 mg/L.

    From a macro-level analysis of the attributes and pathogenic features of HBV, the main pathogenic factor for chronic liver diseases including viral hepatitis, cirrhosis, and liver cancer, the concept of damp-heat insidious pathogen was obtained, according to which, in-depth discussions were undertaken. Adopting syndrome typing of Wei (defense), qi (vital energy), Ying (nutrients), and blood, the pathogens leading to different syndromes as well as new products such as pathological "sputum", "stasis" in the disease process were understood, and then, the pathological "sputum" and "stasis", as the hub, playing a role in chronic lesions of the liver collateral were explained. Finally the pathological "sputum" and "stasis" blend and form cancer toxin. Through a comprehensive understanding of the development of chronic liver diseases, it is clear that damp-heat insidious pathogen, as its initiating factor, always exists in the whole process. We summed up heat clearing, dampness resolving, and detoxification was the principle for treating chronic liver disease.

    Background: Liver biopsy is required to diagnose non-alcoholic steatohepatitis in patients with suspected non-alcoholic fatty liver disease (NAFLD). This study aimed to examine the relationship between sonographic diagnosis of fatty liver with histopathologic abnormalities and liver biopsy findings in patient with NAFLD. Materials and Methods: In this cross-sectional study, a total of 180 patients, with an age range of 18-60 year old, with NAFLD based on ultrasonograghic findings were evaluated. Age, sex, body mass index, diabetes mellitus, hypertension, family history of liver disease and laboratory parameters recorded for all patients. Hence, grade of steatosis and stage of fibrosis were evaluated by liver biopsy. Results: A total of 220 patients were enrolled. Liver biopsy was performed in 180 patients. Mean age was 43 ± 10.6 years old and 66% were male. Ultrasonograghic findings showed mild, moderate and severe NAFLD was define in 100 (55.5%), 72 (40%) and 8 (4.5%) of patients, respectively. Liver biopsies showed that steatosis scores of <5%, 5-33% and 33-66% was define in 56 (31%), 116 (64%) and 9 (5%) of patients, respectively. Furthermore, fibrosis was defined as follow; none 92 (51%), mild 68 (38%), moderate 11 (6%), bridging 5 (3%) and cirrhosis 3 (2%) patients. There was no statistically significant relationship between ultrasonograghic findings and steatosis scores (P = 0.44), but statistically significant relationship was found between ultrasonograghic findings and fibrosis stage (P = 0.017). Conclusion: Findings revealed that, in patients with NAFLD, ultrasonographic finding were not in associate to steatosis, but were in relation with fibrosis stage. PMID:27563632

    Primary liver cancer, the most common histologic types of which are hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC), is the second leading cause of cancer death worldwide. While rising incidence of liver cancer in low-risk areas and decreasing incidence in some high-risk areas has been reported, trends have not been thoroughly explored by country or by histologic type. We examined liver cancer incidence overall and by histology by calendar time and birth cohort for selected countries between 1978 and 2007. For each successive 5-year period, age-standardized incidence rates were calculated from volumes V-IX of the Cancer Incidence in Five Continents electronic database (CI5plus) and the newly released CI5X (volume X) database. Wide global variations persist in liver cancer incidence. Rates of liver cancer remain highest in Asian countries, specifically Eastern and South-Eastern Asian countries. While rates in most of these high-risk countries have been decreasing in recent years, rates in India and several low-risk countries of Africa, Europe, the Americas, and Oceania have been on the rise. Liver cancer rates by histologic type tend to convey a similar temporal profile. However, in Thailand, France, and Italy, ICC rates have increased while HCC rates have declined. We expect rates in high-risk countries to continue to decrease, as the population seroprevalence of hepatitis B virus (HBV) continues to decline. In low-risk countries, targeted screening and treatment of the hepatitis C virus (HCV), treatment of diabetes and primary prevention of obesity, will be key in reducing future liver cancer incidence.

    Background: Non-alcoholic fatty liver is the most chronic liver disease that eventually can become cirrhosis. One of the underlying assumptions for the fatty liver created by inflammation of the hepatocytes. We aimed to assess the association between non-alcoholic fatty liver disease (NAFLD) and sub-clinical inflammation. Materials and Methods: This is a cross-sectional study which was conducted on 55 patients over 30 years, with NAFLD. Fatty liver grade was assessed using liver ultrasound. Liver enzymes (alanine aminotransferase, aspartate aminotransferase), anthropometric characteristics and inflammatory marker C-reactive protein (CRP) were measured. Qualitative variables (sex and fatty liver grade) and quantitative variables such as were compared with independent t-test and Chi-square test. Relationship between fatty liver grade and inflammatory index was assessed with SPSS software (version 20; SPSS, Inc. Chicago, IL, USA). Results: Non-alcoholic fatty liver grades were associated with CRP level and this relationship remains in statistically significant level even after adjusting the effects of confounding variables such as age, sex and body mass index of participants (P = 0.016). Conclusion: In this cross-sectional study, presentation of NAFLD showed a significant correlation with sub-clinical systemic inflammation and CRP level. PMID:27014655

    Despite the introduction of high-technology methods of detection and diagnosis, screening of primary liver cancer (PLC) remains imperfect. To diagnosis PLC earlier, Surface-enhanced Raman spectroscopy (SERS) coupled with cellulose-acetate membrane electrophoresis were introduced to separate human serum albumin and SERS spectra. Three groups (15 normal persons' samples, 17 hepatitis/cirrhosis samples, 15 cases of PLC) of serum albumin were tested. Silver colloid was used to obtain SERS spectra of human serum albumin. Principal component analysis (PCA) and linear discriminant analysis (LDA) were also employed for statistical analysis. The mean Raman spectra of three groups and the difference spectra of any two suggested that the albumin has changed in liver patients. Compared to normal groups, some Raman peaks have shifted or even disappeared in hepatitis/cirrhosis and PLCs groups. The sensitivity and specificity between PLCs and normal groups is 80% and 93.3%. Among hepatitis/cirrhosis and normal groups, the sensitivity is 88.2% and specificity is also 93.3%. Besides, the sensitivity and specificity between PLCs and hepatitis/cirrhosis groups is 86.7% and 76.5%. All the above data and results indicated that early screening of PLC is potential by SERS in different stages of liver disease before cancer occurs.

    The prevalence of invasive mycoses is increasing, especially among patients who are immunocompromised or hospitalized with serious underlying diseases. Such infections are associated with a high morbidity and significant mortality, requiring early diagnosis and appropriate treatment but also an optimal prophylaxis in patients with high risk factors. We report a case of triple fungal infection including an invasive pulmonary aspergillosis by Aspergillus fumigatus, a candidemia by Candida albicans and a Pneumocystis pneumonia. The overall clinical picture of this patient was liver cirrhosis with medical history of immunosuppressive treatment for Crohn disease and a non-hodgkin lymphoma. There was no antifungal prophylaxis for this patient. Under treatment, the issue was unfavourable with multivisceral failure.

    Primary liver cancer is a global disease that is on the increase. Hepatocellular carcinoma (HCC) accounts for most primary liver cancers and has a notably low survival rate, largely attributable to late diagnosis, resistance to treatment, tumour recurrence and metastasis. MicroRNAs (miRNAs/miRs) are regulatory RNAs that modulate protein synthesis. miRNAs are involved in several biological and pathological processes including the development and progression of HCC. Given the poor outcomes with current HCC treatments, miRNAs represent an important new target for therapeutic intervention. Several studies have demonstrated their role in HCC development and progression. While many risk factors underlie the development of HCC, one process commonly altered is iron homeostasis. Iron overload occurs in several liver diseases associated with the development of HCC including Hepatitis C infection and the importance of miRNAs in iron homeostasis and hepatic iron overload is well characterised. Aberrant miRNA expression in hepatic fibrosis and injury response have been reported, as have dysregulated miRNA expression patterns affecting cell cycle progression, evasion of apoptosis, invasion and metastasis. In 2009, miR-26a delivery was shown to prevent HCC progression, highlighting its therapeutic potential. Several studies have since investigated the clinical potential of other miRNAs with one drug, Miravirsen, currently in phase II clinical trials. miRNAs also have potential as biomarkers for the diagnosis of HCC and to evaluate treatment efficacy. Ongoing studies and clinical trials suggest miRNA-based treatments and diagnostic methods will have novel clinical applications for HCC in the coming years, yielding improved HCC survival rates and patient outcomes.

    Multifocal tumors developed either as independent tumors or as intrahepatic metastases, are very common in primary liver cancer. However, their molecular pathogenesis remains elusive. Herein, a patient with synchronous two hepatocellular carcinoma (HCC, designated as HCC-A and HCC-B) and one intrahepatic cholangiocarcinoma (ICC), as well as two postoperative recurrent tumors, was enrolled. Multiregional whole-exome sequencing was applied to these tumors to delineate the clonality and heterogeneity. The three primary tumors showed almost no overlaps in mutations and copy number variations. Within each tumor, multiregional sequencing data showed varied intratumoral heterogeneity (21.6% in HCC-A, 20.4% in HCC-B, 53.2% in ICC). The mutational profile of two recurrent tumors showed obvious similarity with HCC-A (86.7% and 86.6% respectively), rather than others, indicating that they originated from HCC-A. The evolutionary history of the two recurrent tumors indicated that intrahepatic micro-metastasis could be an early event during HCC progression. Notably, FAT4 was the only gene mutated in two primary HCCs and the recurrences. Mutation prevalence screen and functional experiments showed that FAT4, harboring somatic coding mutations in 26.7% of HCC, could potently inhibit growth and invasion of HCC cells. In HCC patients, both FAT4 expression and FAT4 mutational status significantly correlated with patient prognosis. Together, our findings suggest that spatial and temporal dissection of genomic alterations during the progression of multifocal liver cancer may help to elucidate the basis for its dismal prognosis. FAT4 acts as a putative tumor suppressor that is frequently inactivated in human HCC. PMID:26672766

    CA 19.9 serum levels were prospectively determined in 573 patients admitted to hospital for suspicion of pancreatic cancer. The final diagnosis was 77 patients with no malignancy, 389 patients with pancreatic cancer, 37 neuroendocrine pancreatic cancer, 28 cholangiocarcinomas, 4 gallbladder cancer, 27 ampullary carcinomas, and 11 periampullary carcinomas. CA 19.9 was determined using a commercial assay from Roche Diagnostics, and 37 U/ml was considered as the upper limit of normality. Abnormal CA 19.9 serum levels were found in 27%, 81.5%, 85.7%, 59.3%, 63.6%, and 18.9% of patients with benign diseases, pancreatic cancer, cholangiocarcinomas, and ampullary, periampullary, or neuroendocrine tumors. Significantly higher concentrations of CA 19.9 were found in patients with than in those without malignancy or with neuroendocrine tumors. CA 19.9 serum levels were higher in pancreatic cancer or cholangiocarcinoma than in other malignancies (p < 0.0001). CA 19.9 serum levels were also correlated with tumor stage, treatment (significantly lower concentrations in resectable tumors), and tumor location (the highest in those located in the body, the lowest in those in the tail or uncinate) and site of metastases (highest in liver metastases). A trend to higher CA 19.9 serum concentrations was found in patients with jaundice, but only with statistical significance in the early stages. Using 50 or 100 U/ml in patients with jaundice, CA 19.9 was useful as an aid in the diagnosis of pancreatic cancer (sensitivity 77.9%, specificity 95.9%) as well as tumor resectability in pancreatic cancer with different cutoffs according to tumor location and bilirubin serum levels with specificities ranging from 90% to 100%. CA 19.9 is the tumor marker of choice in pancreatic adenocarcinomas, with a clear relationship with tumor location, stage, and resectability.

    Lung cancer is the major cause of cancer related lethality worldwide, and metastasis to distant organs is the pivotal cause of death for the vast majority of lung cancer patients. Accumulated evidence indicates that lung cancer stem-like cells (CSLCs) play important roles in metastagenesis, and these circulating CSLCs may be important targets to inhibit the subsequent metastasis. The present study was aimed at establishing CSLC-targeting polylactic acid (PLA) encapsulated docetaxel nanoparticles for antimetastatic therapy. Cyclic binding peptides were screened on CSLCs in vitro and the peptide CVKTPAQSC exhibiting high specific binding ability to pulmonary adenocarcinoma tissue was subsequently conjugated to the nanoparticles loaded with docetaxel (NDTX). Antimetastatic effect of CSLC-targeting nanoparticles loaded with docetaxel (TNDTX) was evaluated in a nude mouse model of liver metastasis. Results showed that, in the absence of targeting peptide, NDTX hardly exhibited any antimetastatic effect. However, TNDTX treatment significantly decreased the metastatic tumor area in the nude mouse liver. Histopathological and serological results also confirmed the antimetastatic efficacy of TNDTX. To our knowledge, this is the first report on establishing a CSLC-based strategy for lung cancer metastatic treatment, and we hope this will offer a potential therapeutic approach for management of metastatic lung cancer.

    Ethereal embodiment is the attending and focusing on the body through discourses such as meditation, visualisation and massage, and the experiencing a new sense of the embodied being as balanced, connected, centred and of being made whole. This paper continues a previous article titled 'Massaged embodiment of cancer patients'. Data from my doctoral studies are analysed utilising crucial concepts of poststructuralism such as subjectivity, discourse, power and history to examine ethereal embodiment. This paper will address the advantages of visualisation and discusses the link between spirituality, embodiment, and memory.

    Purpose To investigate the second primary cancers (SPCs) in patients with urothelial cancer (UC). Materials and Methods The records of 2,339 patients whose UC was diagnosed between January 1974 and December 2012 were reviewed. All data about characteristics of patients, of UC and, of SPC was, recorded digitally. We investigated the prevalence and the type of second or higher order cancers, and the factors associated with SPC. Results Total 260 patients (11.1%) had SPC, 14 had a third primary cancer and one had a fourth primary cancer. The most common SPC with UC was lung cancer (29.6%). Of all 260 with SPC, 64 (24.6%) had synchronous (within the 6 months) SPC, 120 (46.2%) had subsequent SPC and, 76 (29.2%) had antecedent SPC. The mean duration of SPC was 56 months in patients with subsequent SPC and 75.8 months in patients with antecedent SPC. The mean age at the time of diagnosis of UC was higher in patients with SPC. The ratio of male gender, body mass index, blood type, status of smoking and, occupational risk was similar in both groups. Total amount of smoking and the mean follow-up were higher in patients with SPC. Conclusions The majority of the patients with UC have long life expectancy. In patients with UC, the risk of having another cancer is quite higher than normal population. The physicians managing patients with UC should look for SPC. PMID:27617314

    The drugs used in chemotherapy treatments have little specificity, attack tumor cells, and also injure proliferative tissues. Knowledge of the functions of micronutrients has greatly increased, especially of Selenium (Se) that presents immunomodulatory and antitumor functions. The present study evaluated the health-related quality of life of patients undergoing chemotherapy for the treatment of leukemias and lymphomas (LL) and solid tumors (ST) while receiving Selenium (Se) supplementation. This is a randomized, double-blind, crossover study that evaluated the quality of life (EORTC-QLQ-C30 questionnaire), renal and liver functions of patients supplemented with Se. There was no statistically significant alteration in LL patients. However, the fatigue and nausea scores after 30 days did decrease in this group as well as in the ST group. After 1 year supplementation with Selenium, a more noticeable decrease in the scores concerning fatigue and nausea could be observed in the ST group, when compared with the beginning of the study. The LL patients also presented a decrease in the fatigue scores and physical functions. The kidney function as well as liver function has improved after Selenium supplementation when compared with the placebo intake in LL and ST patients, more remarkably in the LL group. Supplementation with Selenium promotes the reduction of chemotherapy side effects in cancer patients, especially by improving the conditions of patients with fatigue, nausea, and impaired physical function. Renal and liver functions have also improved.

    The aim of this study was to evaluate the effect of radiofrequency ablation (RFA) on malignant hepatic tumors and compare its therapeutic efficacy in hepatocellular carcinoma (HCC) and metastatic liver cancer (MLC). A total of 56 patients with malignant hepatic tumors (34 patients with HCC and 22 patients with MLC) underwent RFA treatment. Two weeks following the RFA treatment, contrast-enhanced abdominal computed tomography scans were used to investigate whether the ablation of the tumors was complete. The patients were followed up for a period ranging from 1 to 93 months, to compare recurrence rates, distant recurrence rates and survival rates. The HCC group exhibited an initial complete ablation rate of 94.1% compared with 95.4% for the MLC group; the difference in ablation rates was not identified to be statistically significant. The recurrence and distant recurrence rates were 14.7% and 11.8%, respectively, for the HCC group and 9.1% and 36.4%, respectively, for the MLC group. The 1-, 3- and 5-year survival rates of the patients with HCC were 86.2, 71.4 and 60.0%, respectively, whereas those for the patients with MLC were 73.9%, 45.4% and 37.5%, respectively. The survival rates of the two groups were identified to be significantly different (P=0.002). RFA treatment was therefore shown to be effective in treating small (<5 cm) malignancies, which is clinically significant. PMID:24669247

    We evaluated the dosimetric effect of a respiration motion, and sought an effective planning strategy to compensate the motion using four-dimensional computed tomography (4D CT) dataset of seven selected liver patients. For each patient, we constructed four different proton plans based on: (1) average (AVG) CT, (2) maximum-intensity projection (MIP) CT, (3) AVG CT with density override of tumor volume (OVR), and (4) AVG CT with field-specific proton margin which was determined by the range difference between AVG and MIP plans (mAVG). The overall effectiveness of each planning strategy was evaluated by calculating the cumulative dose distribution over an entire breathing cycle. We observed clear differences between AVG and MIP CT-based plans, with significant underdosages at expiratory and inspiratory phases, respectively. Only the mAVG planning strategy was fully successful as the field-specific proton margin applied in the planning strategy complemented both the limitations of AVG and MIP CT-based strategies. These results demonstrated that respiration motion induced significant changes in dose distribution of 3D proton plans for mobile liver cancer and the changes can be effectively compensated by applying field-specific proton margin to each proton field.

    Azathioprine hepatotoxicity has been described mainly in renal transplant recipients. Most reported cases are related to lesions of the venous system of the liver: peliosis hepatis, veno-occlusive disease of the liver, perisinusoidal fibrosis, and nodular regenerative hyperplasia of the liver. The most common clinical manifestation of these hepatic vascular lesions is portal hypertension. We present a case of nodular regenerative hyperplasia and perivenous fibrosis in a patient receiving azathioprine for multiple sclerosis. Histological abnormalities were similar to those described in renal transplant patients, and azathioprine was the only potential hepatotoxic agent present. Images Figure 1 Figure 2 PMID:2060883

    Background Fascioliasis has been sporadically associated with chronic liver disease on previous studies. In order to describe the current evidence, we carried out a systematic review to assess the association between fascioliasis with liver fibrosis, cirrhosis and cancer. Methodology and Principal Findings A systematic search of electronic databases (PubMed, LILACS, Scopus, Embase, Cochrane, and Scielo) was conducted from June to July 2015 and yielded 1,557 published studies. Among 21 studies that met inclusion and exclusion criteria, 12 studies explored the association of F. hepatica with liver fibrosis, 4 with liver cirrhosis, and 5 with cancer. Globally these studies suggested the ability of F. hepatica to promote liver fibrosis and cirrhosis. The role of F. hepatica in cancer is unknown. Given the heterogeneity of the studies, a meta-analysis could not be performed. Conclusions Future high-quality studies are needed to determine the role of F. hepatica on the development of liver fibrosis, liver cirrhosis, and cancer in humans. PMID:27681524

    Our objective is to explore the value of liver cancer contrast-enhanced ultrasound (CEUS) and MRI perfusion quantitative analysis in liver cancer and the correlation between these two analysis methods. Rabbit VX2 liver cancer model was established in this study. CEUS was applied. Sono Vue was applied in rabbits by ear vein to dynamically observe and record the blood perfusion and changes in the process of VX2 liver cancer and surrounding tissue. MRI perfusion quantitative analysis was used to analyze the mean enhancement time and change law of maximal slope increasing, which were further compared with the pathological examination results. Quantitative indicators of liver cancer CEUS and MRI perfusion quantitative analysis were compared, and the correlation between them was analyzed by correlation analysis. Rabbit VX2 liver cancer model was successfully established. CEUS showed that time-intensity curve of rabbit VX2 liver cancer showed "fast in, fast out" model while MRI perfusion quantitative analysis showed that quantitative parameter MTE of tumor tissue increased and MSI decreased: the difference was statistically significant (P < 0.01). The diagnostic results of CEUS and MRI perfusion quantitative analysis were not significantly different (P > 0.05). However, the quantitative parameter of them were significantly positively correlated (P < 0.05). CEUS and MRI perfusion quantitative analysis can both dynamically monitor the liver cancer lesion and surrounding liver parenchyma, and the quantitative parameters of them are correlated. The combined application of both is of importance in early diagnosis of liver cancer.

    CD90 is used as a marker for cancer stem cell in liver cancer. We aimed to study the mechanism by which CD90 promoted liver cancer progression and identify the new therapeutic targets on CD90 signal pathway. Ectopic expression of CD90 in liver cancer cell lines enhanced anchorage-independent growth and tumor progression. Furthermore, CD90 promoted sphere formation in vitro and upregulated the expression of the cancer stem cell marker CD133. The CD133 expression was higher in CD45-CD90+ cells in liver cancer specimen. The natural carcinogenic molecules TGF-β-1, HGF, and hepatitis B surface antigen increased the expression of CD90 and CD133. Inhibition of CD90 by either shRNA or antibody attenuated the induction of CD133 and anchorage-independent growth. Lentiviral delivery of CD133 shRNA abolished the tumorigenicity induced by CD90. Ectopic expression of CD90 induced mTOR phosphorylation and AMPK dephosphorylation. Mutation of integrin binding-RLD domain in CD90 attenuated the induction of CD133 and anchorage-independent growth. Similar results were observed after silencing β3 integrin. Signaling analyses revealed that AMPK/mTOR and β3 integrin were required for the induction of CD133 and tumor formation by CD90. Importantly, the energy restriction mimetic agent OSU-CG5 reduced the CD90 population in fresh liver tumor sample and repressed the tumor growth. In contrast, sorafenib did not decrease the CD90+ population. In conclusion, the signal axis of CD90-integrin-mTOR/AMPK-CD133 is critical for promoting liver carcinogenesis. Molecules inhibiting the signal axis, including OSU-CG5 and other inhibitors, may serve as potential novel cancer therapeutic targets in liver cancer. PMID:26556861

    Human liver cancer is the cancer commonly seen clinically. The transcription of ribosomal DNA (rDNA) is a critical step for cells, and epigenetic marks such as post-translational histone modifications have been involved in the regulation of rDNA transcription. But less is known about the pathogenesis of the liver cancers concerning the rDNA transcription regulation. Here we aligned the ChIP-seq data of histone modification markers and CTCF to the human genome assembly which contains a single rDNA repeat in human liver cancer cell and validated their distribution with ChIP-QPCR. Human liver cancer cell possesses a higher enrichment of H3K4me1 and H3K27me3 at ~28 kb within the intergenic spacer (IGS) of rDNA and a higher enrichment of H3K4me3 and H3K27ac upstream of TSS. Furtherly, we studied whether UBF could affect histone modification markers and CTCF at rDNA in human liver cancer cell. UBF depletion leads to a decrease of gene activation mark H3K4me3 across the rDNA promoter. And other histone modification marks and CTCF were not altered after UBF depletion. Taken together, our data showed a high resolution map of histone modification marks at rDNA in human liver cancer cell and provide novel evidence to decipher chromatin-mediated regulation of rDNA in liver cancer.

    Background Uterine cancer (UC) represents 5.1% of all female malignancies in Sweden. Accumulation of UC in families occurs in around 5% of cases. We wanted to identify any familial association between UC and other selected cancers and to study the frequency of Lynch,Cowden and cancer syndromes among consecutive UC patients in Sweden. Methods 481 UC patients were included. Information on the cancer diagnoses of their relatives (first- (FDRs) and second-degree (SDRs) relatives and first cousins) was obtained. The relative frequencies of different cancers among relatives were compared to those in the Swedish general cancer population in 1970 and 2010. Families that fulfilled the criteria for hereditary cancer syndromes were tested for mutations in the causative genes. Families with at least one case of UC in addition to the index patient were compared to families with no additional cases to investigate possible characteristics of putative hereditary cancer syndromes. Results There was an increased prevalence of UC in our study population compared to the Swedish general cancer population in 1970 and 2010 (6% vs. 4% and 3%, respectively). Seven families had Lynch Syndrome according to the Amsterdam II criteria. No families fulfilled the criteria for Cowden syndrome. In total 13% of index patients had at least one relative with UC and these families tended to have more cases of early onset cancer among family members. In addition, 16% of index patients were diagnosed with at least one other cancer. No families fulfilled the criteria for Cowden syndrome. Conclusion We showed a familial clustering of UC among relatives of our index patients. Of the seven families with mutation-verified Lynch Syndrome, only one had been previously diagnosed, highlighting the need to increase gynecologists’ awareness of the importance of taking family history. Our data on multiple cancers and young age of onset in families with uterine cancer is compatible with the existence of additional

    Malnutrition is found in almost 100% of patients with end stage liver disease (ESLD) awaiting transplantation and malnutrition before transplantation leads to higher rates of post-transplant complications and worse graft survival outcomes. Reasons for protein energy malnutrition include several metabolic alterations such as inadequate intake, malabsorption, and overloaded expenditure. And also, stress from surgery, gastrointestinal reperfusion injury, immunosuppressive therapy and corticosteriods use lead to delayed bowl function recovery and disorder of nutrients absorption. In the pretransplant phase, nutritional goals include optimization of nutritional status and treatment of nutrition-related symptoms induced by hepatic decompensation. During the acute post-transplant phase, adequate nutrition is required to help support metabolic demands, replenish lost stores, prevent infection, arrive at a new immunologic balance, and promote overall recovery. In a word, it is extremely important to identify and correct nutritional deficiencies in this population and provide an adequate nutritional support during all phases of liver transplantation (LT). This study review focuses on prevalence, nutrition support, evaluation, and management of perioperative nutrition disorder in patients with ESLD undergoing LT.

    Patients undergoing partial hepatectomy have an increased susceptibility to infection. To investigate whether this increased risk is related to impaired leukocyte function, we studied polymorphonuclear leukocyte (PMN) phagocytosis in patients undergoing a hemihepatectomy because of liver metastasis (LM, n = 11) and in patients undergoing major abdominal surgery because of abdominal malignancy (AM, n = 8). Eight healthy volunteers (HVs) served as controls. Leukocyte suspensions were incubated with fluorescein isothiocyanate-labeled Staphylococcus aureus, and phagocytosis was measured by flow cytometry. Preoperative PMN phagocytosis, in the presence of autologous plasma, was significantly less in patients with LM compared with patients with AM or HVs. This impaired phagocytosis was potentially restored in the presence of normal plasma. The decreased phagocytic capacity of PMNs from patients with LM was not related to levels of known plasma opsonins or phenotypic changes of PMNs. Rather, it was related to a deficiency of unidentified plasma factors. After surgery, the phagocytic capacity of PMNs of patients with AM decreased by approximately 30%, which correlated with decreasing levels of immunoglobulin G and C3. In conclusion, patients with LM had a decreased PMN phagocytic capacity before surgery. This impairment in phagocytosis disappeared 1 week after surgery. We propose that the presence of LM leads to a deficiency of factor(s) in the blood that impairs PMN phagocytic capacity.

    1 Disposition of oral brotizolam (0.5 mg) was studied in male patients with liver cirrhosis (patients) and in other patients (control) matched for age, weight, smoking and drinking habits. 2 Absorption of brotizolam was relatively rapid in both groups with a median peak time (range) of 1.0 (0.5-2.0) h. Peak concentrations were also similar with median values of 7.1 (3.2-10.7) ng/ml in patients and 9.4 (2.9-19.0 ng/ml) in controls. 3 Elimination half-life was longer in patients than in controls. The median values were 12.8 (9.4-25) h and 6.9 (4.4-8.4) h respectively (P < 0.01). In two patients hardly any drug elimination was observed, indicating severe impairment of drug metabolizing activity. The prolongation of the elimination half-life was likely to be due to a decrease in clearance (45 ml/min in patients compared with 64 ml/min in controls), and an increase in volume of distribution (0.62 l/kg and 0.39 l/kg respectively). 4 Median values of protein unbound fraction of brotizolam were 9.2 (7.8-10.4)% in controls and 12.4 (10.4-18.9)% in patients. Clearance of unbound drug was 612 ml/min and 380 ml/min respectively. PMID:6661377

    Abstract Clinical trials have shown life-prolonging effects of antithrombotics in cancer patients, but the molecular mechanisms remain unknown due to the multitude of their effects. We investigated in a mouse model whether one of the targets of antithrombotic therapy, fibrin deposition, stimulates tumour development. Fibrin may provide either protection of cancer cells in the circulation against mechanical stress and the immune system, or form a matrix for tumours and/or angiogenesis in tumours to develop. Mice homozygous for Factor V Leiden (FVL), a mutation in one of the coagulation factors that facilitates fibrin formation, were used to investigate whether hypercoagulability affects tumour development in an experimental metastasis model. Liver metastases of colon cancer were induced in mice with the FVL mutation and wild-type littermates. At day 21, number and size of tumours at the liver surface, fibrin/fibrinogen distribution, vessel density and the presence of newly formed vessels in tumours were analysed. Number and size of tumours did not differ between mice with and without the FVL mutation. Fibrin/fibrinogen was found in the cytoplasm of hepatocytes and cancer cells, in blood vessels in liver and tumour tissue and diffusely distributed outside vessels in tumours, indicating leaky vessels. Vessel density and angiogenesis varied widely between tumours, but a pre-dominance for vessel-rich or vessel-poor tumours or vessel formation could not be found in either genotype. In conclusion, the FVL mutation has no effect on the development of secondary tumours of colon cancer in livers of mice. Fibrin deposition and thus inhibition of fibrin formation by anticoagulants do not seem to affect tumour development in this model. PMID:17635646

    Hyperdynamic circulation in patients with liver cirrhosis is characterized by increased cardiac output and heart rate, and decreased systemic vascular resistance with low arterial blood pressure and currently focused on understanding the pathogenesis because of possibility of developing novel treatment modality. Basically, these hemodynamic alternations arise from portal hypertension. Portosystemic collaterals develop to counterbalance the increased intrahepatic vascular resistance to portal blood flow and induce an increase in venous return to heart. Increased shear stress in vascular endothelial cell related high blood flow by portosystemic shunting contributes to this upregulation of eNOS resulting in NO overproduction. Additionally, bypassing through portosystemic collaterals and escaping degradation of over-produced circulating vasodilators in the diseased liver can promote the peripheral arterial vasodilation. Vasodilation of the systemic and splanchnic circulations lead to a reduced systemic vascular resistance, and increased cardiac output and splanchnic blood flow. Furthermore, neurohumoral vasoconstrictive systems including systemic nervous system, rennin angiotensin aldosterone system, and vasopressin are intensively activated secondary to vasodilation. However, hyperdynamic circulation would be more aggravated by the activated vasoconstrictive systems. With the progression of the cirrhotic process, hyperdynamic alternations can be more profound due to hyporesponsiveness to vasoconstrictors and increased shunt formation in conjunction with autonomic neuropathy. Eventually, splanchnic arterial vasodilation results in an increase portal venous inflow, maintaining the elevated portal venous pressure. Hyperdynamic circulation is intimately involved in portal hypertension with liver cirrhosis, therefore it is reasonable to have an interest in complete understanding of the pathogenesis of hyperdynamic circulation to develop novel treatment modality.
