Abstract
BACKGROUND In 30-50% of patients with colorectal adenomatous polyposis, no germline mutation in the known genes APC, causing familial adenomatous polyposis, MUTYH, causing MUTYH-associated polyposis, or POLE or POLD1, causing polymerase-proofreading-associated polyposis can be identified, although a hereditary aetiology is likely. This study aimed to explore the impact of APC mutational mosaicism in unexplained polyposis. METHODS To comprehensively screen for somatic low-level APC mosaicism, high-coverage next-generation sequencing of the APC gene was performed using DNA from leucocytes and a total of 53 colorectal tumours from 20 unrelated patients with unexplained sporadic adenomatous polyposis. APC mosaicism was assumed if the same loss-of-function APC mutation was present in ≥ 2 anatomically separated colorectal adenomas/carcinomas per patient. All mutations were validated using diverse methods. RESULTS In 25% (5/20) of patients, somatic mosaicism of a pathogenic APC mutation was identified as underlying cause of the disease. In 2/5 cases, the mosaic level in leucocyte DNA was slightly below the sensitivity threshold of Sanger sequencing; while in 3/5 cases, the allelic fraction was either very low (0.1-1%) or no mutations were detectable. The majority of mosaic mutations were located outside the somatic mutation cluster region of the gene. CONCLUSIONS The present data indicate a high prevalence of pathogenic mosaic APC mutations below the detection thresholds of routine diagnostics in adenomatous polyposis, even if high-coverage sequencing of leucocyte DNA alone is taken into account. This has important implications for both routine work-up and strategies to identify new causative genes in this patient group.

Abstract
BACKGROUND Systemic chemotherapy typically converts previously unresectable liver metastases (LM) from colorectal cancer to curative intent resection in ∼15% of patients. This European multicenter phase II trial tested whether hepatic artery infusion (HAI) with triplet chemotherapy and systemic cetuximab could increase this rate to 30% in previously treated patients. PATIENTS AND METHODS Participants had unresectable LM from wt KRAS colorectal cancer. Main non-inclusion criteria were advanced extra hepatic disease, prior HAI and grade 3 neuropathy. Irinotecan (180 mg/m(2)), oxaliplatin (85 mg/m(2)) and 5-fluorouracil (2800 mg/m(2)) were delivered via an implanted HAI access port and combined with i.v. cetuximab (500 mg/m(2)) every 14 days. Multidisciplinary decisions to resect LM were taken after every three courses. The rate of macroscopic complete resections (R0 + R1) of LM, progression-free survival (PFS) and overall survival (OS) were computed according to intent to treat. RESULTS The patient population consisted of 42 men and 22 women, aged 33-76 years, with a median of 10 LM involving a median of six segments. Up to 3 extrahepatic lesions of <1 cm were found in 41% of the patients. A median of six courses was delivered. The primary end point was met, with R0-R1 hepatectomy for 19 of the 64 previously treated patients, 29.7% (95% confidence interval 18.5-40.9). Grade 3-4 neutropenia (42.6%), abdominal pain (26.2%), fatigue (18%) and diarrhea (16.4%) were frequent. Objective response rate was 40.6% (28.6-52.3). Median PFS and OS reached 9.3 (7.8-10.9) and 25.5 months (18.8-32.1) respectively. Those with R0-R1 hepatectomy had a median OS of 35.2 months (32.6-37.8), with 37.4% (23.6-51.2) alive at 4 years. CONCLUSION The coordination of liver-specific intensive chemotherapy and surgery had a high curative intent potential that deserves upfront randomized testing.

Abstract
Arterial complications are a major cause of graft lost after liver transplantation (LT). The aim of our study was to assess the clinical impact of systematic early postoperative injected computed tomographic (CT) scans after LT rather than its performance on demand in the event of abnormalities. Two series of consecutive transplantation patients in different periods (1997-1999, 231 patients versus 2008-2010, 250 patients) were analyzed. During the first period, an injected CT scan was only performed in the event of clinical, biological, or ultrasound abnormalities revealed by tests performed daily during the first week after surgery. During the second period, in addition to standard follow-up examination, an injected CT scan was performed systematically at approximately postoperative day 7. During the first (versus the more recent) period, both recipients (whose ages were 46 ± 13 years versus 50 ± 12 years; P = .004) and donors (whose ages were 42 ± 17 versus 52 ± 17 years; P = .0001) were younger and end-stage liver disease was more common (34% versus 12%; P = .0001), but hepatocellular carcinoma (7% vs 26%; P = .0001) and retransplantation (2% versus 7%; P = .01) were less frequent. Postoperative mortality was higher during the first period (14% versus 4%; P = .0003). The incidence of early arterial thrombosis (<1 month) was similar (1.3% versus 1.6%; P = .78), but that of arterial stenosis was higher with a systematic CT scan (1.7 versus 4.4; P = .07). As a consequence of the early detection and treatment of arterial abnormalities, the repeat LT rate due to late arterial thrombosis was nil in the second period and 2.1% (5/231) in the first period. In conclusion, a systematic CT angiogram at the end of the first postoperative week reduced retransplantation rates due to late hepatic artery thrombosis by detecting patients at risk who required specific treatment.

Abstract
This study was a retrospective analysis of the European Liver Transplant Registry (ELTR) performed to compare long-term outcomes with prolonged-release tacrolimus versus tacrolimus BD in liver transplantation (January 2008-December 2012). Clinical efficacy measures included univariate and multivariate analyses of risk factors influencing graft and patient survival at 3 years posttransplant. Efficacy measures were repeated using propensity score-matching for baseline demographics. Patients with <1 month of follow-up were excluded from the analyses. In total, 4367 patients (prolonged-release tacrolimus: n = 528; BD: n = 3839) from 21 European centers were included. Tacrolimus BD treatment was significantly associated with inferior graft (risk ratio: 1.81; p = 0.001) and patient survival (risk ratio: 1.72; p = 0.004) in multivariate analyses. Similar analyses performed on the propensity score-matched patients confirmed the significant survival advantages observed in the prolonged-release tacrolimus- versus tacrolimus BD-treated group. This large retrospective analysis from the ELTR identified significant improvements in long-term graft and patient survival in patients treated with prolonged-release tacrolimus versus tacrolimus BD in primary liver transplant recipients over 3 years of treatment. However, as with any retrospective registry evaluation, there are a number of limitations that should be considered when interpreting these data.

Abstract
Abstract
Background
The management of patients with colorectal cancer and simultaneously diagnosed liver and lung metastases (SLLM) remains controversial.
Methods
The LiverMetSurvey registry was interrogated for patients treated between 2000 and 2012 to assess outcomes after resection of SLLM, and the factors associated with survival. SLLM was defined as liver and lung metastases diagnosed 3 months or less apart. Survival was compared between patients with resected isolated liver metastases (group 1, control), those with resected liver and lung metastases (group 2), and patients with resected liver metastases and unresected (or unresectable) lung metastases (group 3). An Akaike test was used to select variables for assessment of survival adjusted for confounding variables.
Results
Group 1 (isolated liver metastases, hepatic resection alone) included 9185 patients, group 2 (resection of liver and lung metastases) 149 patients, and group 3 (resection of liver metastases, no resection of lung metastases) 285 patients. Ten variables differed significantly between groups and seven were included in the model for adjusted survival (age, number of liver metastases, synchronicity of liver metastases with primary tumour, carcinoembryonic antigen level, node status of the primary tumour, initial resectability of liver metastases and inclusion in group 3). Adjusted overall 5-year survival was similar for groups 1 and 2 (51·5 and 44·5 per cent respectively), but worse for group 3 (14·3 per cent) (P = 0·001).
Conclusion
Patients who had resection of liver and lung metastases had similar overall survival to those who had undergone removal of isolated liver metastases.

Abstract
Between 2003 and 2012, 42 869 first liver transplantations performed in Europe with the use of either University of Wisconsin solution (UW; N = 24 562), histidine-tryptophan-ketoglutarate(HTK; N = 8696), Celsior solution (CE; N = 7756) or Institute Georges Lopez preservation solution (IGL-1; N = 1855) preserved grafts. Alternative solutions to the UW were increasingly used during the last decade. Overall, 3-year graft survival was higher with UW, IGL-1 and CE (75%, 75% and 73%, respectively), compared to the HTK (69%) (p < 0.0001). The same trend was observed with a total ischemia time (TIT) >12 h or grafts used for patients with cancer (p < 0.0001). For partial grafts, 3-year graft survival was 89% for IGL-1, 67% for UW, 68% for CE and 64% for HTK (p = 0.009). Multivariate analysis identified HTK as an independent factor of graft loss, with recipient HIV (+), donor age ≥65 years, recipient HCV (+), main disease acute hepatic failure, use of a partial liver graft, recipient age ≥60 years, no identical ABO compatibility, recipient hepatitis B surface antigen (-), TIT ≥ 12 h, male recipient and main disease other than cirrhosis. HTK appears to be an independent risk factor of graft loss. Both UW and IGL-1, and CE to a lesser extent, provides similar results for full size grafts. For partial deceased donor liver grafts, IGL-1 tends to offer the best graft outcome.

Abstract
BACKGROUND Associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) was recently developed to induce rapid hypertrophy and reduce post-hepatectomy liver failure in patients with insufficient remnant liver volume (RLV). However, mortality rates >12% have been reported. This study aimed to analyze the perioperative course of ALPPS and to identify factors associated with morbi-mortality. METHODS Between April 2011 and September 2013, 62 patients operated in 9 Franco-Belgian hepatobiliary centres underwent ALPPS for colorectal metastases (N = 50) or primary tumors, following chemotherapy (N = 50) and/or portal vein embolization (PVE; N = 9). RESULTS Most patients had right (N = 31) or right extended hepatectomy (N = 25) (median RLV/body weight ratio of 0.54% [0.21-0.77%]). RLV increased by 48.6% [-15.3 to 192%] 7.8 ± 4.5 days after stage1, but the hypertrophy decelerated beyond 7 days. Stage2 was cancelled in 3 patients (4.8%) for insufficient hypertrophy, portal vein thrombosis or death and delayed to ≥9 days in 32 (54.2%). Overall, 25 patients (40.3%) had major complication(s) and 8 (12.9%) died. Fourteen patients (22.6%) had post-stage1 complication of whom 5 (35.7%) died after stage2. Factors associated with major morbi-mortality were obesity, post-stage1 biliary fistula or ascites, and infected and/or bilious peritoneal fluid at stage2. The latter was the only predictor of Clavien ≥3 by multivariate analysis (OR: 4.9; 95% CI: 1.227-19.97; p = 0.025). PVE did not impact the morbi-mortality rates but prevented major cytolysis that was associated with poor outcome. CONCLUSIONS The inter-stages course was crucial in determining ALPPS outcome. The factors of high morbi-mortality rates associated with ALPPS are linked to the technique complexity.

Abstract
INTRODUCTION The intravitreal dexamethasone implant has shown efficacy in the treatment of macular edema (ME) arising after retinal venous occlusions (central or branch), and in the treatment of non-infectious uveitis. The purpose of this study was to evaluate the efficacy of this implant in the treatment of other diffuse macular edemas with an inflammatory mechanism. MATERIALS AND METHODS We carried out a retrospective cohort study over 2 years: from January 2012 to December 2013, including all patients who received at least one injection of intravitreal dexamethasone implant, excluding venous occlusions and non-infectious uveitis. The primary study parameter was the progression of visual acuity. The study protocol had the approval of the institutional review board of the respective clinical ethics committees, and was conducted in accordance to the tenets of the Declaration of Helsinki. RESULTS Eighty patients were included. Eighty-eight percent of patients were pseudophakic. The indications for treatment were: diabetic ME when anti-VEGF were ineffective (53%), ME after retinal detachment (RD) (22%), ME of Irvine-Gass syndrome (16%), ME after endophthalmitis (4%), macular telangiectasia (4%), ME secondary to retinitis pigmentosa (1%). The mean ETDRS visual acuity was 53.7 letters prior to injection, improving to 62.3 letters after injection (P<0.001). The average gain in visual acuity was 6.7 letters [4.53;8.84] (P<0.001) in patients treated for diabetic ME, 9.6 letters [6.1;13.1] (P<0.001) in patients with ME after RD, and 15.2 letters [10.25;20.28] (P<0.001) for Irvine-Gass syndrome. The mean duration of efficiency was 4.6 months, with a median of 3.8 months. CONCLUSION The intravitreal dexamethasone implant appears to be an effective second-line treatment even in patients with diabetic ME after failure or in the case of contraindication of anti-VEGF. It is also effective and well tolerated in patients with ME after RD, as well as in patients with Irvine-Gass syndrome.

Abstract
BACKGROUND For patients with initially unresectable liver metastases from colorectal cancer, chemotherapy can downsize metastases and facilitate secondary resection. We assessed the efficacy of bevacizumab plus modified FOLFOX-6 (5-fluorouracil/folinic acid, oxaliplatin) or FOLFOXIRI (5-fluorouracil/folinic acid, oxaliplatin, irinotecan) in this setting. PATIENTS AND METHODS OLIVIA was a multinational open-label phase II study conducted at 16 centres in Austria, France, Spain, and the UK. Patients with unresectable liver metastases were randomised to bevacizumab (5 mg/kg) plus mFOLFOX-6 [oxaliplatin 85 mg/m(2), folinic acid 400 mg/m(2), 5-fluorouracil 400 mg/m(2) (bolus) then 2400 mg/m(2) (46-h infusion)] or FOLFOXIRI [oxaliplatin 85 mg/m(2), irinotecan 165 mg/m(2), folinic acid 200 mg/m(2), 5-fluorouracil 3200 mg/m(2) (46-h infusion)] every 2 weeks. Unresectability was defined as ≥1 of the following criteria: no possibility of upfront R0/R1 resection of all lesions; <30% residual liver volume after resection; metastases in contact with major vessels of the remnant liver. Resectability was evaluated by multidisciplinary review. The primary end point was overall resection rate (R0/R1/R2). Efficacy end points were analysed by intention-to-treat analysis. RESULTS In patients assigned to bevacizumab-FOLFOXIRI (n = 41) or bevacizumab-mFOLFOX-6 (n = 39), the overall resection rate was 61% [95% confidence interval (CI) 45% to 76%] and 49% (95% CI 32% to 65%), respectively (difference 12%; 95% CI -11% to 36%). R0 resection rates were 49% and 23%, respectively. Overall tumour response rates were 81% (95% CI 65% to 91%) with bevacizumab-FOLFOXIRI and 62% (95% CI 45% to 77%) with bevacizumab-mFOLFOX-6. Median progression-free survival (PFS) was 18·6 (95% CI 12.9-22.3) months and 11·5 (95% CI 9.6-13.6) months, respectively. The most common grade 3-5 adverse events were neutropenia (bevacizumab-FOLFOXIRI, 50%; bevacizumab-mFOLFOX-6, 35%) and diarrhoea (30% and 14%, respectively). CONCLUSIONS Bevacizumab-FOLFOXIRI was associated with higher response and resection rates and prolonged PFS versus bevacizumab-mFOLFOX-6 in patients with initially unresectable liver metastases from colorectal cancer. Toxicity was increased but manageable with bevacizumab-FOLFOXIRI. CLINICALTRIALSGOV NCT00778102.

Abstract
OBJECTIVE To assess gingival recession (GR) in manual and power toothbrush users and evaluate the relationship between GR and gingival abrasion scores (GA). METHODS This was an observational (cross-sectional), single-centre, examiner-blind study involving a single-brushing exercise, with 181 young adult participants: 90 manual brush users and 91 oscillating-rotating power brush users. Participants were assessed for GR and GA as primary response variables. Secondary response variables were the level of gingival inflammation, plaque score reduction and brushing duration. Pearson correlation was used to describe the relationship between number of recession sites and number of abrasions. Prebrushing (baseline) and post-brushing GA and plaque scores were assessed and differences analysed using paired tests. Two-sample t-test was used to analyse group differences; ancova was used for analyses of post-brushing changes with baseline as covariate. RESULTS Overall, 97.8% of the study population had at least one site of ≥1 mm of gingival recession. For the manual group, this percentage was 98.9%, and for the power group, this percentage was 96.7% (P = 0.621). Post-brushing, the power group showed a significantly smaller GA increase than the manual group (P = 0.004); however, there was no significant correlation between number of recession sites and number of abrasions for either group (P ≥ 0.327). CONCLUSIONS Little gingival recession was observed in either toothbrush user group; the observed GR levels were comparable. Lower post-brushing gingival abrasion levels were seen in the power group. There was no correlation between gingival abrasion as a result of brushing and the observed gingival recession following use of either toothbrush.

Genome-wide CNV analysis in 221 unrelated patients and targeted high-throughput sequencing reveal novel causative candidate genes for colorectal adenomatous polyposis. Int J Cancer 2014; 136:E578-89.

Abstract
To uncover novel causative genes in patients with unexplained adenomatous polyposis, a model disease for colorectal cancer, we performed a genome-wide analysis of germline copy number variants (CNV) in a large, well characterized APC and MUTYH mutation negative patient cohort followed by a targeted next generation sequencing (NGS) approach. Genomic DNA from 221 unrelated German patients was genotyped on high-resolution SNP arrays. Putative CNVs were filtered according to stringent criteria, compared with those of 531 population-based German controls, and validated by qPCR. Candidate genes were prioritized using in silico, expression, and segregation analyses, data mining and enrichment analyses of genes and pathways. In 27% of the 221 unrelated patients, a total of 77 protein coding genes displayed rare, nonrecurrent, germline CNVs. The set included 26 candidates with molecular and cellular functions related to tumorigenesis. Targeted high-throughput sequencing found truncating point mutations in 12% (10/77) of the prioritized genes. No clear evidence was found for autosomal recessive subtypes. Six patients had potentially causative mutations in more than one of the 26 genes. Combined with data from recent studies of early-onset colorectal and breast cancer, recurrent potential loss-of-function alterations were detected in CNTN6, FOCAD (KIAA1797), HSPH1, KIF26B, MCM3AP, YBEY and in three genes from the ARHGAP family. In the canonical Wnt pathway oncogene CTNNB1 (β-catenin), two potential gain-of-function mutations were found. In conclusion, the present study identified a group of rarely affected genes which are likely to predispose to colorectal adenoma formation and confirmed previously published candidates for tumor predisposition as etiologically relevant.

Abstract
The European Liver and Intestine Transplant Association (ELITA) and the European Liver Transplant Registry (ELTR) coordinated the distribution to European liver transplantation centers of an electronic questionnaire, developed by the first author, concerning the definition of extended criteria liver donation (ECD) and the implication for informed consent of transplant recipients. Completed questionnaires were received from 35 centers. All centers accepted ECD liver donors. The criteria for defining a liver donor as ECD were as follows: steatosis in 33 centers (94%); age up to 80 years in 15 centers (43%); serum sodium >165 mmol/L in 25 centers (71%); intensive care unit (ICU) stay with ventilation longer than 7 days in 17 centers (48%); aspartate aminotransferase (AST) >90 U/L, in 6 centers (17%); body mass index (BMI) >30 in 19 centers (54%); alanine aminotransferase (ALT) >105 U/L in 8 centers (23%); serum bilirubin >3 mg/dL in 15 centers (43%); and all criteria together in 2 centers (6%). Thirty-one centers informed the transplantation candidate of the ECD status of the donor, 20 (65%) when the patient registered for transplantation, 1 (3%) when an ECD liver became available, and 10 centers (32%) on both occasions. Thirteen centers required the liver transplantation candidate to sign a special consent form. Twenty centers informed the potential recipient of the donor's serology. Only 6 centers informed the potential recipient of any high-risk behavior of the donor.

Abstract
Reported cases of "pure" duplication of the entire short arm of chromosome 16 (16p) are rare, with only 7 patients described in the literature. We report on a female infant with de novo 16p duplication localized to the short arm of chromosome 6, detected by chromosomal analysis and characterized by array CGH and fluorescence in situ hybridization. This baby girl presented with clinical symptoms characteristic of patients with duplications of the short arm of chromosome 16: psychomotor retardation, constitutional growth delay and specific dysmorphic features, including proximally placed hypoplastic thumbs. In addition, she exhibited evidence of neonatal hemochromatosis as shown by direct hyperbilirubinemia, iron overload and elevated liver enzyme levels. To our knowledge, this is the first report of signs of neonatal hemochromatosis in a patient with 16p duplication.

Abstract
BACKGROUND The resectability criteria for malignant liver tumours have expanded during the past two decades. The use of vascular reconstruction after hepatectomy has been integral in this process. However, the majority of reports are anecdotal. This is a retrospective analysis of the techniques, morbidity, mortality and risk factors of liver resections with vascular reconstruction based on a large series from a single centre. METHODS Patients who underwent hepatic resection combined with vascular resection and reconstruction between 1997 and 2009 were included in this study. Indications for surgery, morbidity and 90-day mortality are reported along with factors predictive of operative mortality. RESULTS Eighty-four patients had liver resection with 97 vascular resections and reconstruction. There were 44 men and 40 women with a mean(s.d.) age of 56·9(12·1) years. Mean(s.d.) follow-up was 37·3(34·1) months. All patients had primary or metastatic liver tumours. The perioperative morbidity rate was 62 per cent (52 patients) and the operative mortality rate 14 per cent (12). Predictors of operative mortality were: bilirubin level exceeding 34 µmol/ml (P = 0·023), indocyanine green retention rate at 15 min over 10 per cent (P = 0·031), duration of ischaemia (P = 0·011), amount of blood transfused (P = 0·025) and combined major extrahepatic procedure (P = 0·042). Actuarial 3- and 5-year survival rates were 44 and 26 per cent respectively. CONCLUSION Liver resection with combined vascular resection and reconstruction can be performed in selected patients with acceptable morbidity and mortality. The lack of therapeutic alternatives and the poor outcome of non-operative management seem to justify this approach. The identification of risk factors should help improve patient selection and postoperative outcome as well as facilitate objective risk communication with surgical candidates.

Abstract
UNLABELLED The aim of this study is to assess postoperative results obtained by different knee implants. The main implant types differences are given by generally implant design and by PCL substituting systems that are used. MATERIAL AND METHOD Between 04.2004 - 02.2012 we have performed 506 total knee arthroplasties (TKA), on a group of 460 patients. Our choice, was for cemented total knee prostheses, using PCL-substituting systems. Regarding general design and PCL-substituting systems of the implant we had divided the main group in three lots. In order to assess post operative result we had used the American Knee Society Score(AKSS). RESULTS AND DISCUSSIONS All prostheses types that we had implanted, had registered satisfactory values of AKSS. Our study showed that one group scored higher values of AKSS, compared the other two, but there are not statistical semnificative differences (p=0,09).

Abstract
BACKGROUND The oncological benefit of repeat hepatectomy for patients with recurrent colorectal metastases is not yet proven. This study assessed the value of repeat hepatectomy for these patients within current multidisciplinary treatment. METHODS Consecutive patients treated by repeat hepatectomy for colorectal metastases between January 1990 and January 2010 were included. Patients undergoing two-stage hepatectomy were excluded. Postoperative outcome was analysed and compared with that of patients who had only a single hepatectomy. RESULTS A total of 1036 patients underwent 1454 hepatectomies for colorectal metastases. Of these, 288 patients had 362 repeat hepatectomies for recurrent metastases. Some 225 patients (78·1 per cent) had two hepatectomies, 52 (18·1 per cent) had three hepatectomies, and 11 patients (3·8 per cent) had a fourth hepatectomy. Postoperative morbidity following repeat hepatectomy was similar to that after initial liver resection (27·1 per cent after first, 34·4 per cent after second and 33·3 per cent after third hepatectomy) (P = 0·069). The postoperative mortality rate was 3·1 per cent after repeat hepatectomy versus 1·6 per cent after first hepatectomy. Three- and 5-year overall survival rates following first hepatectomy in patients who underwent repeat hepatectomy were 76 and 54 per cent respectively, compared with 58 and 45 per cent in patients who had only one hepatectomy (P = 0·003). In multivariable analysis, repeat hepatectomy performed between 2000 and 2010 was the sole independent factor associated with longer overall survival. CONCLUSION Repeat hepatectomy for recurrent colorectal metastases offers long-term survival in selected patients.
