AbstractPrimary biliary cirrhosis (PBC) is a classical autoimmune liver disease for which effective immunomodulatory therapy is lacking. Here we perform meta-analyses of discovery data sets from genome-wide association studies of European subjects (n=2,764 cases and 10,475 controls) followed by validation genotyping in an independent cohort (n=3,716 cases and 4,261 controls). We discover and validate six previously unknown risk loci for PBC (Pcombined<5 × 10−8) and used pathway analysis to identify JAK-STAT/IL12/IL27 signalling and cytokine–cytokine pathways, for which relevant therapies exist.

Prevalence of biliary lithiasis in a Sicilian population of chronic renal failure patients.

2003

BACKGROUND The aim of this study was to evaluate the prevalence of biliary lithiasis (BL) and associated risk factors in a population of undialysed patients with chronic renal failure (CRF), and to compare these with findings we had obtained previously in chronic haemodialysis (HD) patients and in subjects from the general population located in the same geographic region. METHODS A total of 118 CRF patients on conservative treatment were included in the study. In all subjects, we measured several clinical and humoral parameters potentially correlated with BL. Liver and biliary tract ultrasonography was performed with a 3.5 MHz linear probe after at least 12 h of fasting. RESULTS The prevale…

Mutational Characterization of the Bile Acid Receptor TGR5 in Primary Sclerosing Cholangitis

2010

Background: TGR5, the G protein-coupled bile acid receptor 1 (GPBAR1), has been linked to inflammatory pathways as well as bile homeostasis, and could therefore be involved in primary sclerosing cholangitis (PSC) a chronic inflammatory bile duct disease. We aimed to extensively investigate TGR5 sequence variation in PSC, as well as functionally characterize detected variants.Methodology/Principal Findings: Complete resequencing of TGR5 was performed in 267 PSC patients and 274 healthy controls. Six nonsynonymous mutations were identified in addition to 16 other novel single-nucleotide polymorphisms. To investigate the impact from the nonsynonymous variants on TGR5, we created a receptor mod…

A phase II study of oxaliplatin (O) and gemcitabine (G) first line chemotherapy in patients with advanced biliary tract cancers

2005

Background: Biliary tract cancers are uncommon tumors with a poor prognosis and most patients (pts) present with invasive and inoperable disease at diagnosis. Chemotherapy represents a palliative treatment, but single or combination-drug schedules have demonstrated poor response rates with a median survival less than 6 months. Recently O and G have showed an interesting activity as single agents in this group of pts. Methods: We carried out a multicenter phase II study to evaluate the efficacy and safety of combined O and G in locally advanced and metastatic biliary tract carcinoma. The schedule of chemotherapy included O 100 mg/m2 on day 1 and G 1000 mg/m2 on days 1 and 8, every 21 days. I…

Gemcitabine plus sorafenib versus gemcitabine alone in advanced biliary tract cancer: a double-blind placebo-controlled multicentre phase II AIO stud…

2014

Background: Since sorafenib has shown activity in different tumour types and gemcitabine regimens improved the outcome for biliary tract cancer (BTC) patients, we evaluated first-line gemcitabine plus sorafenib in a double-blind phase II study. Patients and methods: 102 unresectable or metastatic BTC patients with histologically proven adenocarcinoma of gallbladder or intrahepatic bile ducts, Eastern Cooperative Oncology Group (ECOG) 0–2 were randomised to gemcitabine (1000 mg/m2 once weekly, first 7-weeks + 1-week rest followed by once 3-weeks + 1-week rest) plus sorafenib (400 mg twice daily) or placebo. Treatment continued until progression or unacceptable toxicity. Tumour samples were p…

A Phase II Trial of Fixed-Dose Rate Gemcitabine plus Capecitabine in Metastatic/Advanced Biliary Tract Cancer Patients

2011

<i>Background:</i> This phase II trial was conducted to determine the activity and safety of the combination of fixed-dose rate (FDR) gemcitabine and capecitabine in metastatic biliary tract cancer (BTC) patients. <i>Methods:</i> Patients with unresectable BTC who had pathologically confirmed adenocarcinoma, no prior chemotherapy, Eastern Cooperative Oncology Group (ECOG) performance status ≤1 and measurable disease were enrolled. Treatment consisted of FDR gemcitabine at 800 mg/m<sup>2</sup> on days 1 and 8 every 21 days with capecitabine administered orally b.i.d. in equal doses (650 mg/m<sup>2</sup> b.i.d.) for 14 days (28 doses). <i>…

Risk estimation for biliary tract cancer: Development and validation of a prognostic score.

2017

Background & Aims Biliary tract cancer is a rare tumour entity characterized by a poor prognosis. We aimed to identify prognostic factors and create a prognostic score to estimate survival. Methods Clinical data of the training set, consisting of 569 patients treated from 2000 to 2010 at Hannover Medical School, were analysed. A prognostic model defining three prognostic risk groups was derived from Cox regression analyses. The score was applied and validated in an independent cohort of 557 patients from four different German centres. Results Median overall survival (OS) was 14.5 months. If complete resection was performed, the patients had a significantly improved OS (23.9 months; n=242) a…

Antitumoral Effects of Lipids A, Clinical Studies

2009

Cancer remains the second leading cause of death, after cardiovascular diseases, in industrialized countries. The first goal to achieveis to prevent cancer occurrence or to diagnose it at an early and curable stage. Some screening strategies have been developed, with controversies across countries, for several cancer type; colorectal, breasts or prostate cancer for example.
