Abstract
We report the case of a 53-year-old patient subjected to percutaneous embolization of right and middle hepatic veins to induce liver segments 2–3 hypertrophy before extended right hepatic resection for a locally advanced type IIIa perihilar cholangiocarcinoma. Hepatic vein embolization (HVE) was performed 3 weeks after surgical recanalization of left portal vein (severely narrowed at its origin due to tumor infiltration) interposing an internal jugular vein graft between main and distal left portal vein. Nine days after HVE, future liver remnant volume increased from 395 to 501 cc, i.e. 25.1% of standardized total liver volume, allowing to perform a radical right hepatic trisectionectomy plus caudatectomy. He was discharged home on postoperative day 15th after an uneventful postoperative course, with no sign of posthepatectomy liver failure.

Abstract
BACKGROUND The aim of this study was to evaluate the safety and efficacy of percutaneous ablation for hepatocellular carcinoma (HCC) hepatic recurrence along surgical resection margins to achieve complete cure or bridge for additional treatment. No current recommendations exist for these lesions. METHODS Retrospective review of post-surgical recurrent HCC located along surgical margins treated by percutaneous ultrasound-guided ablation from 2006-2014. Ablation was performed by radiofrequency ablation (RFA) or percutaneous ethanol injection (PEI), selected for recurrence in proximity to extrahepatic organs. RESULTS In total, nine patients (49-82 y, mean 73.8±8.3) were treated for 13 recurrent HCC nodules (9-35 mm, mean 21.5±8.1) located along resection margins by RFA (11 nodules) and PEI (2 nodules). Mean time between surgery and percutaneous ablation was 64 months (range 10-149). At a mean follow-up of 17 months (±9), complete ablation was achieved in 9 nodules (69.2%, 8 after RF, 1 after PEI) and partial ablation was achieved in 4 nodules (3 after RFA, 1 after PEI). Complications were limited to minor abdominal pain in 2 patients requiring medical therapy (15.3%). Of the 4 partially ablated nodules, subsequent therapy achieved complete response in 3 nodules (1 patient with TACE, 1 patient with stereotactic radiotherapy, and one with liver transplantation), while the last nodule progressed despite subsequent TACE. CONCLUSIONS HCC recurrence along the surgical margin can be safely and effectively treated by percutaneous therapy, despite the misconception of the surgical margin as a hostile location. Percutaneous treatment may bridge the patient for additional therapy.

Abstract
Colorectal cancer is the third most common cancer worldwide, with 1.2 million patients diagnosed annually. In late-stage colorectal cancer, the most commonly used targeted therapies are the monoclonal antibodies cetuximab and panitumumab, which prevent epidermal growth factor receptor (EGFR) activation. Recent studies have identified alterations in KRAS and other genes as likely mechanisms of primary and secondary resistance to anti-EGFR antibody therapy. Despite these efforts, additional mechanisms of resistance to EGFR blockade are thought to be present in colorectal cancer and little is known about determinants of sensitivity to this therapy. To examine the effect of somatic genetic changes in colorectal cancer on response to anti-EGFR antibody therapy, here we perform complete exome sequence and copy number analyses of 129 patient-derived tumour grafts and targeted genomic analyses of 55 patient tumours, all of which were KRAS wild-type. We analysed the response of tumours to anti-EGFR antibody blockade in tumour graft models and in clinical settings and functionally linked therapeutic responses to mutational data. In addition to previously identified genes, we detected mutations in ERBB2, EGFR, FGFR1, PDGFRA, and MAP2K1 as potential mechanisms of primary resistance to this therapy. Novel alterations in the ectodomain of EGFR were identified in patients with acquired resistance to EGFR blockade. Amplifications and sequence changes in the tyrosine kinase receptor adaptor gene IRS2 were identified in tumours with increased sensitivity to anti-EGFR therapy. Therapeutic resistance to EGFR blockade could be overcome in tumour graft models through combinatorial therapies targeting actionable genes. These analyses provide a systematic approach to evaluating response to targeted therapies in human cancer, highlight new mechanisms of responsiveness to anti-EGFR therapies, and delineate new avenues for intervention in managing colorectal cancer.

Abstract
INTRODUCTION Chronic biliary obstruction consequence of a bile duct injury may require liver transplantation (LT) in case of secondary biliary cirrhosis, intractable pruritus or reiterate episodes of cholangitis. "Mass-forming" sclerosing cholangitis leading to secondary portal vein thrombosis and pre-sinusoidal portal hypertension has not been reported so far. PRESENTATION OF CASE We present the case of a patient who underwent laparoscopic cholecystectomy for Mirizzi syndrome. The persistent bile duct obstruction due to a residual gallstone fragment was treated by a prolonged biliary stenting. Following repeated bouts of cholangitis, a fibrous centrohepatic scar developed, conglobating and obstructing the main branches of the portal vein and of the biliary tree. The patient developed secondary portal vein thrombosis and portal hypertension. After an extensive diagnostic work-up, including surgical exploration to rule out malignancy, the case was successfully managed by liver transplantation. DISCUSSION Mass-forming sclerosis of the bile duct and biliary bifurcation may develop as a consequence of chronic biliary obstruction and prolonged stenting. Secondary portal vein thrombosis and pre-sinusoidal portal hypertension represents an unusual complication, mimicking Klatskin tumor. CONCLUSION A timely and proper management of post-cholecystectomy complications is of mainstay importance. Early referral to a specialized hepato-biliary center is strongly advised.

Abstract
Biliary cystadenoma is a rare benign cystic tumor of the liver. The mainstay of treatment is complete resection, either by enucleation or by formal hepatectomy, since incomplete removal entails not only constant recurrence but also the risk of malignant transformation to cystadenocarcinoma. A case of symptomatic centrohepatic biliary cystadenoma involving the main vasculobiliary structures of the liver is reported. After an unsuccessful attempt at resection resulting in an intrahepatic biliary injury, relief of jaundice and radical excision were achieved by total hepatectomy and liver transplantation. The patient is now alive and well 4 years after transplant, disease-free, with normal liver and renal function while receiving everolimus monotherapy. This is the first report of liver transplantation performed for the treatment of this tumor. With the case on the background, diagnostic aspects and available therapeutic strategies for biliary cystadenoma are reviewed and discussed.

Abstract
PURPOSE We determined the gene copy numbers for MET, for its transcriptional activator MACC1 and for its ligand hepatocyte growth factor (HGF) in liver metastases from colorectal carcinoma (mCRC). We correlated copy numbers with mRNA levels and explored whether gain and/or overexpression of MET and MACC1 predict response to anti-Met therapies. Finally, we assessed whether their genomic or transcriptional deregulation correlates with pathologic and molecular parameters of aggressive disease. EXPERIMENTAL DESIGN One hundred three mCRCs were analyzed. Copy numbers and mRNA were determined by quantitative PCR (qPCR). Thirty nine samples were implanted and expanded in NOD (nonobese diabetic)/SCID (severe combined immunodeficient) mice to generate cohorts that were treated with the Met inhibitor JNJ-38877605. In silico analysis of MACC1 targets relied on genome-wide mapping of promoter regions and on expression data from two CRC datasets. RESULTS No focal, high-grade amplifications of MET, MACC1, or HGF were detected. Chromosome 7 polysomy and gain of the p-arm were observed in 21% and 8% of cases, respectively, and significantly correlated with higher expression of both Met and MACC1. Met inhibition in patient-derived xenografts did not modify tumor growth. Copy number gain and overexpression of MACC1 correlated with unfavorable pathologic features better than overexpression of Met. Bioinformatic analysis of putative MACC1 targets identified elements besides Met, whose overexpression cosegregated with aggressive forms of colorectal cancer. CONCLUSIONS Experiments in patient-derived xenografts suggest that mCRCs do not rely on Met genomic gain and/or overexpression for growth. On the basis of pathologic correlations and bioinformatic analysis, MACC1 could contribute to CRC progression through mechanisms other than or additional to Met transcriptional upregulation.

Abstract
We report herein a domino orthotopic liver transplantation (LT), from a 38-year-old woman undergoing liver-kidney transplantation (LKT) for primary hyperoxaluria type I (PH1) to a recipient with cirrhosis and hepatocellular carcinoma. Delayed onset of PH1 and renal failure and 10% residual alanine-glyoxylate aminotransferase (AGT) activity in domino liver justified its use for domino procedure. The clinical course after LKT was similar to that described in other series, including ours. Renal function started promptly and maintained despite sustained hyperoxaluria from dissolution of oxalotic deposits. Conversely, the domino recipient manifested severe hyperoxaluria and developed nephrolithiasis and renal insufficiency with rapid progression over 2 months. A new LT resulted in slow decrease of oxaluria and improvement of renal function. Therefore, PH1 behaved quite differently in these two patients, leading us to conclude that domino LT using livers from PH1 patients should be considered very carefully, only as a bridge to definitive LT in recipients with critical clinical conditions.

The authors report a case of a large tumour, located in the right hepatic lateral segments, (size: 15 cm), consisting of a hepatocellular carcinoma (size: 10 cm) and an intrahepatic cholangiocarcinoma (size: 5 cm). The mass was detected by ultrasonography during an examination for abdominal pain in an 80-year-old female. After tumour biopsy and histological examination, hepatic resection was performed. The postoperative course was uneventful and the patient was discharged 6 days after surgery. The rarity of this double cancer is stressed.

Abstract
The development in the number of patients for renal transplants has not been matched to the kidneys supplied. On this subject the authors think that this chronic deficit could be improved by making use of all the organs by using a series of technical means during bench surgery; which enable optimisation of use of kidneys with vascular abnormalities or those injured upon removal. The authors report their experience of 450 renal transplants operated between January 1981 and December 1985 and of the evolution vascular bench surgical techniques which enable use of a considerable number of kidneys which would otherwise have been discarded. Moreover, it helped the implant, shortened surgery time without prolonging hot ischemia, and did not increase the number of complications.
