14106 Background: Due to extent of tumour and underlying liver disease primary liver cancer, hepatocellular(HCC) as well as cholangiocellular(CCC), has extremely poor prognosis. The tyrosinekinase and mTOR inhibitor sirolimus, is registered for preventing allograft rejection. It retard experimental liver tumours in rats, and has antiangiogenic effects as well. Methods: Patients with a nonoperable HCC or CCC, with a Karnofsky >70, and the diagnosis confirmed by biopsy or alfa-fetoprotein (>700ug/ml) were eligible. Ethic committee approved the study and informed consent was signed. The daily Sirolimus dose was adjusted to a 6–10 μg/L through-concentration.Twenty patients were to be enrolled in a nonrandomized study. The primary endpoint was to detect a radiological tumor response rate, defined by RECIST criteria, and secondary endpoint was to study the safety profile. CT or MRI were repeated every third month. The study was approved by the Etic Committee of Göteborg University. Results: Eleven patients with HCC and nine with CCC were included. Overall respone rate was 5%, which ocurred in a patient patient with HCC. The PR lasted for 15 months (RR 9% for HCC). Four patients with HCC had SD for median 7 months (range 5–18). Of the patients with CCC four had SD. Median duration of SD was 4 months (range 1 - 7). Median survival for patients with HCC was 7 months (range 2–20) and CCC 4 months (range 2–24) Discussion: There is low evidence supporting the use of chemotherapy for primary liver cancer. For HCC, one PR and 4 SD in this pilot study indicate that sirolimus might be of interest to study in a phase II trial, since the toxicity of sirolimus was low. In the european SILVER study,the impact of sirolimus for patients transplanted for HCC will be clarified. Experimentally, the antiangiogenetic effects of sirolimus has been boosted by combining with 5-FU and gemcitabine. This might translate to impoved response rate also for liver cancer. Conclusions: This pilot study suggests that sirolimus have a tumour effect in patients with HCC. No significant financial relationships to disclose.

<p>The impact of social influences on food choices in college settings is of great importance because students are vulnerable to new forming identities at this time. The purpose of this pilot study is to determine the degree to which social influences impact food choices in a sample of college students. A 22-item survey instrument was created to determine the extent to which students have experienced being influenced by others when making food related purchasing decisions. A total of 257 out of a 323 students invited (80% response rate) in 11 sections of a personal health course responded to the survey. The overwhelming majority of respondents were reportedly comfortable ordering whatever they wanted when in the presence of their friends (n=249; 97%). Students were more likely to feel pressure to make a healthy choice than an unhealthy choice if everyone else was (45.1% vs. 31.5%), but fewer felt this way when asked specifically if their friends were ordering (28.4% vs. 21%). Social influences surrounding food choices are a topic that has gained momentum recently, however more research needs to be conducted to determine the reasons why social influences affect certain college students especially in comparing healthy versus unhealthy food choices.</p>

Primary liver cancer, consisting predominantly of hepatocellular carcinoma (HCC) and cholangiocarcinoma (CCA), remains one of the most lethal malignancies worldwide. This high malignancy is related to the complex and dynamic interactions between tumour cells, stromal cells and the extracellular environment. Novel in vitro models that can recapitulate the tumour are essential in increasing our understanding of liver cancer. Herein, primary liver cancer-derived organoids have opened up new avenues due to their patient-specificity, self-organizing ability and potential recapitulation of many of the tumour properties. Organoids are solely of epithelial origin, but incorporation into co-culture models can enable the investigation of the cellular component of the tumour microenvironment. However, the extracellular component also plays a vital role in cancer progression and representation is lacking within current in vitro models. In this review, organoid technology is discussed in the context of liver cancer models through comparisons to other cell culture systems. In addition, the role of the tumour extracellular environment in primary liver cancer will be highlighted with an emphasis on its importance in in vitro modelling. Converging novel organoid-based models with models incorporating the native tumour microenvironment could lead to experimental models that can better recapitulate liver tumours in vivo.

Abstract Background Primary liver cancer (PLC) is the fifth and second leading cause of death in Japan and Taiwan, respectively. The aim of this study was to compare the economic burden of PLC between the two countries using the cost of illness (COI) method and identify the key factors causing the different trends in the economic burdens of PLC. Materials and methods We calculated the COI every 3 years using governmental statistics of both countries (1996–2014 data for Japan and 2002–2014 data for Taiwan). The COI was calculated by summing the direct costs, morbidity costs, and mortality costs. We compared the COIs of PLC in both countries at the USD-based cost. The average exchange rate during the targeted years was used to remove the impact of foreign exchange volatility. Results From 1996 to 2014, the COI exhibited downward and upward trends in Japan and Taiwan, respectively. In Japan, the COI in 2014 was 0.70 times the value in 1996, and in Taiwan, the COI in 2014 was 1.16 times greater than that in 1996. The mortality cost was the greatest contributor in both countries and had the largest contribution ratio to the COI increase in Japan. However, the direct cost in Taiwan had the largest contribution ratio to the COI decrease. Conclusions To date, the COI of PLC in Japan has continuously decreased, whereas that in Taiwan has increased. Previous health policies and technological developments are thought to have accelerated the COI decrease in Japan and are expected to change the trend of COI of PLC, even in Taiwan.

ObjectiveAlpha-1 antitrypsin deficiency (AATD) is a common, potentially lethal inborn disorder caused by mutations in alpha-1 antitrypsin (AAT). Homozygosity for the ‘Pi*Z’ variant of AAT (Pi*ZZ genotype) causes lung and liver disease, whereas heterozygous ‘Pi*Z’ carriage (Pi*MZ genotype) predisposes to gallstones and liver fibrosis. The clinical significance of the more common ‘Pi*S’ variant remains largely undefined and no robust data exist on the prevalence of liver tumours in AATD.DesignBaseline phenotypes of AATD individuals and non-carriers were analysed in 482 380 participants in the UK Biobank. 1104 participants of a multinational cohort (586 Pi*ZZ, 239 Pi*SZ, 279 non-carriers) underwent a comprehensive clinical assessment. Associations were adjusted for age, sex, body mass index, diabetes and alcohol consumption.ResultsAmong UK Biobank participants, Pi*ZZ individuals displayed the highest liver enzyme values, the highest occurrence of liver fibrosis/cirrhosis (adjusted OR (aOR)=21.7 (8.8–53.7)) and primary liver cancer (aOR=44.5 (10.8–183.6)). Subjects with Pi*MZ genotype had slightly elevated liver enzymes and moderately increased odds for liver fibrosis/cirrhosis (aOR=1.7 (1.2–2.2)) and cholelithiasis (aOR=1.3 (1.2–1.4)). Individuals with homozygous Pi*S mutation (Pi*SS genotype) harboured minimally elevated alanine aminotransferase values, but no other hepatobiliary abnormalities. Pi*SZ participants displayed higher liver enzymes, more frequent liver fibrosis/cirrhosis (aOR=3.1 (1.1–8.2)) and primary liver cancer (aOR=6.6 (1.6–26.9)). The higher fibrosis burden was confirmed in a multinational cohort. Male sex, age ≥50 years, obesity and the presence of diabetes were associated with significant liver fibrosis.ConclusionOur study defines the hepatobiliary phenotype of individuals with the most relevant AATD genotypes including their predisposition to liver tumours, thereby allowing evidence-based advice and individualised hepatological surveillance.
