Approval for this study was obtained from the local ethics committee of both the University of Tsukuba and Fukushima Medical University School of Medicine, and a signed informed consent was obtained from each subject. We synthesized different peptides encoding the extracellular domains of human-M3R. The N-terminal of human-M3R has a 66-mer amino acid sequence, and we divided this domain into three segments accordingly. The sequences were MTLHNNSTTSPLFPNISSSWIHSPSDAGLP for N-terminal 1, IHSPSDAGLPPGTVTHFGSYNVSRAAGNFS for N-terminal

2 and NVSRAAGNFSSPDGTTDDPLGGHTVWQV for N-terminal 3 (Sigma-Aldrich Japan, Ishikari, Japan). These three peptides were mixed and used for the peptide antigens of the N-terminal region. We also synthesized three peptides corresponding EPZ015666 to the sequences of the three extracellular loops of human-M3R, whose sequences were FTTYIIMNRWALGNLACDLW for the first extracellular loop, KRTVPPGECFIQFLSEPTITFGTAI for the second and VLVNTFCDSCIPKTFWNLGY for selleckchem the third (Sigma-Aldrich Japan). As a negative peptide, we also synthesized a 25-mer peptide whose sequence

was SGSGSGSGSGSGSGSGSGSGSGSGS (Sigma-Aldrich Japan). We have established previously a peptide-based ELISA for detection of anti-M3R antibodies.[6] Briefly, M3R peptide and negative peptide solution (100 μL/well at 10 μg/mL) in 0.1 M Na2CO3 buffer, pH 9.6, was adsorbed onto a Nunc-Immuno plate (Nalge Nunc International, Rochester, NY, USA) overnight at 4°C and blocked with 5% bovine serum albumin (Wako Pure Chemical Industries, selleck inhibitor Osaka, Japan) in phosphate-buffered saline (PBS) for 1 h at 37°C. The test serum sample to be examined

at 1:50 dilution in blocking buffer was incubated for 2 h at 37°C. The plates were then washed six times with 0.05% Tween-20 in PBS, and 100 μL of solution of alkaline phosphatase-conjugated goat antihuman immunoglobulin G (Fc; American Qualex, San Clemente, CA, USA) diluted 1:1000 in PBS was added for 1 h at room temperature. After nine washes, 100 μL of p-nitrophenyl phosphate (Sigma-Aldrich Japan) solution was added at a final concentration of 1 mg/mL as alkaline phosphatase substrate. Plates were incubated for 30 min at room temperature in the dark, and absorbance was measured at 405 nm by plate spectrophotometry. Measurements were performed in triplicate and standardized between experiments by using the absorbance value of the positive control. Data are expressed as mean ± standard deviation (SD) or median. Differences between groups were examined for statistical significance using the Mann–Whitney U-test, while differences in frequencies were analyzed by the Fisher’s exact test. A P-value less than 0.05 denoted the presence of a statistically significant difference. THE TITERS OF anti-M3R antibodies against the N-terminal region in PBC patients (0.408 ± 0.341) were significantly higher than in CHC patients (0.124 ± 0.097), NASH patients (0.169 ± 0.099), PSC patients (0.182 ± 0.

Predictable pharmacokinetics and pharmacodynamics allow a fixed dose of rivaroxaban without coagulation monitoring.[2] It has a half-life of up to 12 hours, its absorption is not affected by food, and one-third of the drug is eliminated by the kidneys, while two-thirds undergo metabolism in the liver.[2] Specific labeling restrictions for rivaroxaban regarding impaired hepatic function are based

on both the Child-Pugh classification and liver-related exclusion criteria applied in pivotal trials.[2] It is currently contraindicated in patients with liver disease associated with coagulopathy, cirrhosis Child Class B or C, and clinically relevant bleeding risk.[2] When compared to warfarin, rivaroxaban’s acquisition cost is higher, but this may be counterbalanced by costs of monitoring, patient’s inconvenience, and healthcare provider’s time required for managing test CT99021 cell line results.[2] C59 wnt supplier In fact, a recent study showed that rivaroxaban is more cost-effective than warfarin for prevention of recurrent venous thromboembolism.[4] Although major and clinically relevant nonmajor bleeding rates were similar between warfarin and rivaroxaban, the rates of intracranial bleeding were significantly lower in the rivaroxaban group, but significantly higher with regard to gastrointestinal bleed.[5] Current concerns about the lack of an antidote for rivaroxaban may be alleviated

when a promising agent such as Andexanet Alfa (Clinicaltrials.gov: NCT01758432) gains regulatory approval. Premature discontinuation of rivaroxaban, like any anticoagulant, can increase the risk of thrombotic events and therefore documentation of complete clot resolution is essential.[2] “
“Despite standardization of surgical selleckchem methods in biliary reconstruction, immunosuppression and post-operative management, biliary complications continue to be a major cause of morbidity

and mortality after liver transplantation (LT). Early identification of biliary complications after LT is critical due to the potential for graft and patient injury. Biliary complications include biliary strictures, bile leaks, biliary stones/debris, sphincter of Oddi dysfunction, mucoceles and hemobilia. Many of these complications can be managed with a combination of endoscopic and percutaneous therapy and this has minimized the need for post-transplant biliary surgery. “
“Superior mesenteric artery (SMA) syndrome, a rare form of proximal intestinal obstruction, occurs when the third portion of duodenum passes through a narrowed opening between the SMA and abdominal aorta. It has been described in association with anorexia nervosa, burns as well as severe weight loss due to various etiologies. The mechanism is a loss of the mesenteric fat pad from undue weight loss. The course may be acute or insidious with nonspecific presentations of postprandial epigastric pain, nausea, and vomiting. Panendoscopy usually identifies reflux-related injury.

The tumor involved the medulla oblongata and the upper cervical spinal cord. Traditional MR imaging findings were unclear with regard to the differential

diagnosis between intramedullary glioma or a tumefactive demyelinating lesion, but an increase in regional cerebral blood volume and a decrease in fractional anisotropy of the lesion correctly suggested a high-grade glioma. MR PWI and DTI may prove helpful to diagnose glioblastoma of the cervical cord when other imaging features are inconclusive. “
“The integrity of the fornix using diffusion tensor imaging (DTI) in adolescent participants with acute mild traumatic brain injury (mTBI) compared to a demographically matched control group was examined. Fractional anisotropy (FA) in the fornix was elevated in the mild traumatic brain injured group. Performance on the Automated Neuropsychological Assessment Metrics (ANAM) was lower in the group with mTBI. A relation was found between lower performance selleck inhibitor on cognitive tasks and higher FA. The potential role of fornix injury as a basis of memory and processing speed deficits in mTBI is discussed. “
“The use of

an MK0683 order ultrasound-based evaluation of the optic nerve sheath diameter (ONSD) has previously been demonstrated for detecting raised intracranial pressure. In order to be feasible in clinical workup, the test qualities of transorbital ultrasonography need to be determined. The aim of this study was therefore to establish normal values and to assess the intra- and interobserver reliability of this method. Using a 9-3 MHz linear array transducer, the ONSD of 40 healthy subjects was independently measured by 2 investigators. Depicting the optic nerve and its sheath was possible in all individuals. The mean ONSD was 5.4 ± .6 mm with a range of 4.3-7.6 mm. The intraobserver reliability analyzed with Cronbach’s Alpha was found to be high with values

between .92 and .97. Pearson’s correlation coefficient between the 2 investigators was .81 on the right side and this website .84 on the left. There was no correlation between ONSD and age, body mass index, or gender. Transorbital B-mode sonography is a feasible method to assess the ONSD with a high intra- and interobsever reliability. Normal values on ONSD are presented in this study that will be useful in future studies on pathological conditions. “
“Amygdala enlargement (AE) has been reported as an epileptogenic focus in subtypes of temporal lobe epilepsy (TLE). The purpose of this study was to investigate the clinical, morphological, and pathological characteristics of AE. We retrospectively reviewed the clinical data and imaging findings of 23 TLE patients with ipsilateral AE. We performed morphological MR analyses using FreeSurfer and voxel-based morphometry (VBM) in 14 of the 23 patients and in 20 controls whose images were obtained by a 3.0-Tesla MRI. A pathological study was also performed in 2 patients who underwent operations.

42 However, it should be emphasized that we did not formally evaluate size or location between platforms on a lesion-by-lesion basis. Furthermore, we did not formally quantify differences in contrast-to-noise between platforms. Many of the lesions missed or seen as smaller on the 1.5T platform may be because of higher noise on the 3T platform. There are several limitations of our study worth noting. Overall sample size was small, particularly when considering the subgroup that underwent cognitive testing. This urges caution in interpreting our results.

Of further concern, when compared to typical MS populations, our patients were less cognitively impaired (only Venetoclax nmr 13% compared to a more commonly reported 40-70% prevalence of cognitive impairment), better educated (mean level of education 15.9 ± 2.7 years, when compared to a recent cohort (mean 14.2 ± 2.1 years),43 and were preselected to have active disease. Thus, our sample had a restricted range of cognitive selleck kinase inhibitor function and other aspects perhaps not generalizable to a typical MS cohort. Given these issues and sample size, further studies are necessary to confirm and extend our findings, particularly with regard to the cognition-MRI associations. We did not assess hypointense lesions

on FLAIR images, which perhaps should be assessed in future studies. Our population was less disabled and earlier in the disease course as compared

to a general MS sample typically encountered in neurology practice.44 Disease duration and physical impairment as measured by EDSS score were relatively low, potentially restricting the range available to show appropriate clinical-MRI correlations. We also did not include spinal scanning, which can also contribute to disability.45 Regarding the comparison between 1.5T and 3T, although there were many similarities between the protocols used, the comparison between the 2 approaches was not completely optimal. Though scan reviewers were blinded to magnet strength, image quality find more did differ between 1.5T and 3T platforms, so full blinding was impossible, possibly introducing bias. Additionally, hardware and acquisition software differed between the 2 platforms. For example, our 3T MRI was equipped with an 8-channel coil while the 1.5T was equipped with a 4-channel one, which could have contributed to increased resolution on the 3T scanner independent of magnet strength. While voxel size and other major parameters were similar, differences in gradient strength, TR, and TE were made in order to optimize image quality and stay within scan time and SAR limits. Raters did not independently review each scan which could potentially introduce bias.

The investigators then generated reporter HEALs by transducing lentiviruses expressing firefly luciferase under the control of the albumin promoter into HEP/FIB+TMNK1 cultures, and the encapsulated HEALs were implanted at an intraperitoneal (IP) site in athymic nude mice. Bioluminescence

imaging showed that the IP site could support the HEALs. Albumin promoter activity was maintained for several weeks, and human albumin and alpha-1-antitrypsin were secreted in the mouse sera. HEALs were reproducibly engrafted (91.6% of 131 mice transplanted) and microcomputed Selleckchem JQ1 tomography angiography of extracted HEALs confirmed host vessel recruitment to, around, and inside the implant. HEAL-humanized mice could be rapidly and reproducibly generated from fresh and also cryopreserved hepatocytes. Moreover, unlike humanized chimeric mouse models, HELAs were maintained in immunocompetent and non-liver-injury mice for up to 8 days. HEAL-humanized mice expressed various human CYPs. Because major drug metabolites can be missed in standard animal models because of differences in drug-metabolism pathways among species, the investigators assessed whether the mice

could be used for the identification of major metabolites. Debrisoquine (DB) is a CYP2D6 substrate converted to 4-hydroxydebrisoquined (4-OHDB) in humans, but not in mice. 2 In fact, HEAL-humanized mice metabolized DB to 4-OHDB. More important, CYP2D6 is responsible for the metabolism of 25% of known drugs and its highly polymorphic nature contributes to significant interindividual learn more variability. 15 The investigators prepared HEALs from two donors with different Protein Tyrosine Kinase inhibitor levels of CYP2D6 and compared the ability of mice harboring the HEALs to metabolize DB. Mice with HEALs from the donor with lower levels of CYP2D6 metabolized DB less efficiently than those with HEALS from the donor with higher expression levels. Thus, HEAL-humanized mice can be used to detect breakdown products of drugs, which are missed

in standard mouse models. Drug-drug interactions are critical determinants of drug efficacy and safety because of the potential for drugs to alter the therapeutic or toxic effect of concomitantly administered compounds. Finally, the investigators explored the utility of the humanized mice for modeling toxic drug-drug interactions in vivo. Mice were first given rifampin (RIF) and then a therapeutic dose of acetoaminophen (APAP), a hepatotoxin at a high dose because of the CYP-mediated formation of N-acetyl-p-benzoquinone (NAPQI). 16 Although mice were resistant to RIF+APAP as a result of species-specific drug-drug interaction and HEAL-humanized mice given either RIF and APAP alone showed no sign of liver injury, HEAL-humanized mice given RIF+APAP showed evidence of human hepatocellular injury. Thus, HEAL-humanized mice can be used for screening hepatotoxic drug-drug combinations and doses invivo.

There were no bleeding events attributable to lack of efficacy. One case of nausea, possibly related to BIOSTATE administration, was reported. These results suggest that BIOSTATE is safe and effective for the treatment and prophylaxis http://www.selleckchem.com/products/pd-0332991-palbociclib-isethionate.html of bleeding in children with VWD. “
“Blood flow properties play important

roles in the regulation and formation of thrombus. To evaluate the influence of blood flow on thrombus formation in haemophilia, whole blood samples were obtained from FVIII-deficient (FVIII−/−) and wild-type (FVIII+/+) mice (n = 6 respectively), and from six human volunteers. Anti-FIXa aptamer was added to human blood to model acquired haemophilia B. Recalcified whole blood samples containing corn trypsin inhibitor and danaproid were perfused over the microchip coated with collagen and tissue thromboplastin at shear rates of 1100 and 110 s−1. Thrombus formation in the capillary was quantified by monitoring flow pressure changes. The intervals to 5 kPa (T5) and 40 k Pa (T40) reflect the onset and growth of thrombus formation respectively. Furthermore, fibrin and platelets in thrombi were quantified by immunostaining. T5 at both shear rates were similar in FVIII−/− and FVIII+/+ mice. T40 of FVIII−/− mice (1569 ± 565 s) was significantly delayed compared with FVIII+/+ mice (339 ± 78 s) at 110 s−1 (P < 0.05), but not at 1100 s−1. The delay was normalized by adding human FVIII

(2 IU mL−1). Similarly, adding anti-FIXa aptamer to human blood prolonged T40 at 110 s−1 (P < 0.01), but not at 1100 s−1. Impaired production buy PF-562271 selleck screening library of fibrin due to anti-FIXa aptamer at 110 s−1 was shown in the immunostained thrombus. Our perfusion experiments demonstrated that shear rates influence thrombus formation patterns in haemophilia, and that reduced activity of intrinsic tenase (FIXa-FVIIIa) becomes evident under venous shear rates. “
“Ensuring optimal musculoskeletal health is one of

the primary aims of the multidisciplinary team providing comprehensive care for people with hemophilia. This chapter provides an update on the principles for the physiotherapy management of joint and muscle bleeding and chronic arthropathy. Current guidelines on physical activity, sport, and the management of the aging hemophilic patient together with the recent emergence of biomechanical evaluation of musculoskeletal health are discussed. “
“Summary.  Coagulation factor VIII (FVIII) is usually evaluated using activated partial thromboplastin time-based one-stage clotting assays. Guidelines for clotting factor assays indicate that a calibration curve should be included each time the assay is performed. Therefore, FVIII measurement is expensive, reagent- and time-consuming. The aim of this study was to compare FVIII activities obtained using the same fully automated assay that was calibrated once (stored calibration curve) or each time the assay was performed.

Gal-9 mRNA is elevated up to 20-fold in co-cultures of infected Huh7. 5s and human monocytes after four days (P=0.02), and increases further with time. To test whether Gal9 levels change with differentiation, we induced macrophage maturation in THP-1 cells with PMA. Basal Gal-9 increases fourfold in mature THP-1 macrophages compared to THP-1 monocytes, with a further Gal-9 increase click here in THP-1 macrophages exposed to HCV-infected

hepatocytes or IFN-y. Human monocytes differentiated into M1s produced 22-fold more Gal-9 than those differentiated into M2s (p<0.02). Conclusions: Gal-9 is produced by monocytes after exposure to HCV-infected Huh7. 5s, and is further heightened during monocyte to macrophage differentiation. HCV-infected cells directly stimulate Gal-9, possibly via contact and uptake by monocytes or macrophages. We are currently investigating whether this occurs via endosomal toll-like receptors. Therapies targeting Gal-9 might provide

an immune boost to help eradicate virus in HCV patients. Disclosures: The following people have nothing to disclose: Noah M. Harwood, Lucy GoldenMason, Hugo R. Rosen, John A. Mengshol Background: A previous report showed that pretreatment upregulation of hepatic ISGs had a stronger association with the treatment-resistant IL28B minor genotype (Ml) (TG/GG at rs8099917) than with the treatment-sensitive lL28B major genotype (MA) (Tt at rs8099917) (Gastroenterology, 2010). However, it is unknown how hepatic ISGs are up-regulated in MI patients and why patients with high levels RG7204 of ISG expression cannot eliminate HCV. Methods: We compared the expression of ISGs in the liver and blood of 146 patients with chronic hepatitis C (CH-C) who received PEGylated-IFN and RBV therapy. Gene expression profiles in the liver and blood of 85 patients were analyzed using Affymetrix GeneChips. Furthermore, ISG expression in liver lobules and portal areas was analyzed using a laser capture microdissection (LCM) method. HCV replication analysis

was performed by using an infectious genotype 1a clone, pH77S. 3/Gluc2A that included a Gaussia luciferase reporter gene. Results: ISG expression was correlated between the liver and blood of the MA patients, while no correlation was observed in MI patients. This loss of correlation was selleck inhibitor due to impaired infiltration of immune cells into the liver lobules of Ml patients, as demonstrated by regional gene expression analysis in liver lobules and portal areas using LCM and immunohistochemical staining. The expression of chemokines, CCL19, CCL21, CCL5 and CXCL13 etc. were significantly repressed in Ml liver. Despite having lower levels of immune cells, hepatic ISGs were up-regulated in MI liver and they were found to be significantly correlated with the expression of IL28 A/B, IFN-4, and WNT5A, while hepatic ISGs in MA liver were not correlated with IFN-λ4 (no expression) and WNT5A.

The average age was 34 years (range, 8–56) and the average follow-up was 3 years (range, 1–6). Regarding minor orthopaedic surgery, that is to say radiosynovectomies, 27 joints were treated (intra-articular injections) in 27 patients. Knees were injected with yttrium (90Y), while ankles and elbows were injected

with rhenium (186Rh). Twenty radiosynovectomies were performed with APCCs (FEIBA), and seven with rFVIIa (NovoSeven). With regard to the group of major orthopaedic procedures, six patients underwent eight orthopaedic operations: three total knee arthroplasties (Fig. 1), one total hip arthroplasty (Fig. 2), one fixation of bone fracture, one ankle arthrodesis (Fig. 3), one removal of hardware Silmitasertib chemical structure of the ankle fusion and one knee arthrodesis. In this group, six procedures were performed with rFVIIa (NovoSeven) and two with APCCs (FEIBA). Overall, of the 35 orthopaedic procedures, 22 were performed with FEIBA and 13 with NovoSeven. Concerning minor non-orthopaedic surgery, 52 patients underwent 52 surgical procedures: 37 central catheter placements, 10 dental extractions, two inguinal hernias, http://www.selleckchem.com/products/PLX-4032.html one lipoma, one hydrocele and one cataract. Regarding major non-orthopaedic surgery, five patients underwent five procedures: one thoracotomy (lobectomy), one craniotomy, one piloroplasty, one appendicectomy and one corneal transplant. Overall,

of the 57 non-orthopaedic procedures, 23 were performed with FEIBA and 34 with NovoSeven. The data and results of this study are summarized in MCE公司 Tables 1 and 2. Regarding FEIBA treatment in minor surgery, the initial dose was 100 IU kg−1. After 6 h, we continued with 50 IU kg−1 every 12 h for at least 4 days (radiosynovectomies). In minor non-orthopaedic procedures, the dose was continued until day 14. In patients who underwent surgery with haemostatic control achieved by means of rFVIIa, the initial dose of rFVIIa in minor procedures (both orthopaedic and non-orthopaedic) was 90–120 μg kg−1. During postoperative days

1–5, the dose was 2–4 × 90–120 μg kg−1 q3–6 h for 24 h. In major procedures (both orthopaedic and non-orthopaedic), the dose was 120 μg kg−1 pre-operatively, 120 μg kg−1 q 3 h day 2/day 3–5, and then 90–120 μg kg−1 q 6 h until day 14. Until a decade ago, major surgery in patients with haemophilia and an inhibitor was extremely rare. However, since then, substantial experience has been accumulated regarding adequate haemostatic treatment to cover these patients during any kind of surgery. Surgery requires effective haemostasis to reduce wound haematomas that may ultimately become infected and jeopardize the long-term outcome. FEIBA and rFVIIa have been used in our series as haemostatic agents, with a high rate of satisfactory results but with one bleeding complication rate after major orthopaedic procedure.

Among various tumors, pancreatic ductal adenocarcinoma (PDAC) typically develops in an unusually disordered microenvironment, which contributes to its highly aggressive behavior. Since anti-vascular endothelial

growth factor (VEGF) (Avastin) has failed to demonstrate a survival benefit in PDAC, we need to re-visit the basic biology of this disease and understand what makes it so refractory to the anti-angiogenic approaches that are clinically effective in other neoplasms. To address this issue, we specifically focused on the process of neovascularization where bone marrow-derived cells (BMDCs) play a role during pancreatic tumorigenesis. We have identified subsets of BMDCs that regulate key processes during development of the neovessels through paracrine Hedgehog signaling. Considering the importance of systemic responses occurring check details in tumor bearing hosts, we are currently using genetically engineered mice, which spontaneously develop PDAC, Pdx1-Cre;LSL-KrasG12D;p53lox/+ strain, to clarify critical events that can trigger aberrant angiogenesis in pancreatic cancer. These studies allow us to provide insights into the cellular and molecular mechanisms of pancreatic tumorigenesis and have an implication for the design of therapies against this difficult disease. “
“Renal

PCI 32765 dysfunction is a common complication of liver transplantation (LT), related to hepatorenal syndrome with end-stage liver disease or calcineurin-inhibitor nephrotoxicity. Chronic kidney disease (CKD) is also a common problem MCE公司 in long-term survivors post-LT. This study was done to investigate

the association between renal functional status soon after LT and the development of CKD. We retrospectively evaluated 63 patients who were aged 18 years or older, and underwent LT at Tohoku University Hospital. The estimated glomerular filtration rate (eGFR) was calculated by the Modification of Diet in Renal Disease study equation for Japan. Before transplantation, 25 patients (39.7%) were diagnosed with CKD (eGFR, <60 mL/min per 1.73 m2). The incidence of CKD was 22.4% (13/58) at 2 years, 23.2% (13/56) at 3 years and 22.7% (12/54) at 5 years. The patients with CKD at 2 years post-transplant were more likely to have a history of glomerulonephritis, and were significantly older at the time of LT, compared to those without CKD. Levels of eGFR of less than 60 mL/min per 1.73 m2 in the first month post-transplant and a volume of intraoperative blood loss of more than 300 mL/kg were predictive factors for the development of CKD at 2 years post-transplant and thereafter. We have shown that there is an improvement of renal function in the majority of patients after LT. Regardless of the presence of pre-existing CKD, both renal function status at the first month post-transplant and a volume of intraoperative blood loss were predictive factors for the development of CKD at 2 years post-transplant and thereafter.

Another difference may have been that we administered microspheres primarily by lobar injection, as opposed to the other study, where many applications were done in segmental or subsegemental fashion. Therefore, the radioactive dose within the tumor may have been too low to induce partial or complete devascularization, but high enough to effectively slow down tumor growth, resulting in increased TTP. Moreover, we followed a more conservative approach in the determination of necrosis and measured only those necrotic areas that were associated with the largest diameter of a particular tumor nodule.12, 13 Ill-defined or small areas of necrosis on the margins

of a nodule, which were not uncommon, were not considered. Therefore, in our study radioembolization behaves to some extent like systemic therapy with the multikinase inhibitor sorafenib, which also does not show Opaganib chemical structure significant radiological changes but a significantly enhanced TTP, translating in an enhanced overall survival.5 GDC 0068 In comparison with the phase III trial leading

to approval of sorafenib (SHARP trial), the median overall survival in our HCC sample treated by Y-90 microsphere was even slightly longer (16.4 months as compared to 10.7 months). It is clear that due to a lower rate of patients with extrahepatic metastases and a number of other potential selection biases, our results are not comparable to those of this well-designed double-blind, placebo-controlled trial. However, the overall survival rate as well as the substratified survival rates are similar to what have been reported 上海皓元医药股份有限公司 in the only other recently published large sample analyzing Y-90 glass microspheres for the treatment of HCC.17 Thus, our data indicate that Y-90 therapy requires further attention as a therapeutical option for the treatment of selected patients with advanced intrahepatic tumors, in particular with PVT and even in patients with limited extrahepatic disease. The position of Y-90 microsphere treatment within the treatment algorithm of HCC

is still to be defined. We report the results from an analysis of the first European sample of patients with intrahepatic advanced liver cancer treated with Y-90 glass microspheres. We demonstrate a very good toxicity profile, even in patients with advanced liver cirrhosis, as well as encouraging data for TTP and survival. As suggested by previous experiences in a U.S. study, our data further underline the role of Y-90 radioembolization as a locoregional therapy in patients with locally advanced tumor stages with or without PVT, and good liver function. Moreover, our data highlight the necessity for randomized controlled trials comparing and/or combining Y-90 glass microsphere radioembolization with TACE in BCLC B patients and with systemic therapy in BCLC C patients.
