Despite excellent 1-year survival, morbidity in benchmark cases remains high with half of patients developing severe complications during 1-year follow-up. Benchmark cutoffs targeting morbidity parameters offer a valid tool to assess higher risk groups.

Intrahepatic cholangiocarcinoma (ICC) is the second most common type of primary cancer in the liver. ICC is an aggressive cancer with poor prognosis and limited therapeutic strategies. The identification of new drug targets and prognostic biomarkers is an important clinical challenge for ICC. The presence of an abundant stroma is a histological hallmark of ICC. Given the well-established role of the stromal compartment in the progression of cancer diseases, we hypothesized that relevant biomarkers could be identified by analyzing the stroma of ICC. By combining laser capture microdissection and gene expression profiling, we demonstrate that ICC stromal cells exhibit dramatic genomic changes. We identified a signature of 1,073 nonredundant genes that significantly discriminate the tumor stroma from nontumor fibrous tissue. Functional analysis of differentially expressed genes demonstrated that up-regulated genes in the stroma of ICC were related to cell cycle, extracellular matrix, and transforming growth factor beta (TGFb) pathways. Tissue microarray analysis using an independent cohort of 40 ICC patients validated at a protein level the increased expression of collagen 4A1/COL4A1, laminin gamma 2/LAMC2, osteopontin/SPP1, KIAA0101, and TGFb2 genes in the stroma of ICC. Statistical analysis of clinical and pathological features demonstrated that the expression of osteopontin, TGFb2, and laminin in the stroma of ICC was significantly correlated with overall patient survival. More important, multivariate analysis demonstrated that the stromal expression of osteopontin was an independent prognostic marker for overall and disease-free survival. Conclusion: The study identifies clinically relevant genomic alterations in the stroma of ICC, including candidate biomarkers for prognosis, supporting the idea that tumor stroma is an important factor for ICC onset and progression. (HEPATOLOGY 2013;58:1992-2000 I ntrahepatic cholangiocarcinomas (ICC) account for 5%-10% of liver primary cancers. 1 ICC usually arise from epithelial cells of the intrahepatic small bile ducts, although a recent report in mice suggested that ICC might also originate from the conversion of mature hepatocytes. 2 Over the last decade, the incidence of ICC has increased significantly in Western countries. 3,4 This trend could be related to a better histological diagnosis of ICC and/or to the rising incidence of the main risk factors for ICC: cholangitis, chronic hepatitis B and C, diabetes, and obesity. 5 Liver resection remains the only curative treatment for ICC but is associated with a high rate of recurrence. 6 Recently, we showed that hilar lymph node metastasis,

Satellite nodules, hilar lymph node metastases and perineural invasion are risk factors for recurrence following resection with curative intent for ICC. Repeat hepatectomy and labelled yttrium-90 radiotherapy may improve survival after intrahepatic recurrence.

For initially unresectable huge ICCs, chemotherapy with Ytt-90 radioembolization is an effective downstaging method that allows for secondary resectability.

A high CV of TAC concentrations was found to be predictive of TAC-related toxicity and poorer survival.

Background. Liver transplantation (LT) from controlled donation after circulatory death (cDCD) was initiated in France in 2015 under a protocol based on the use of normothermic regional perfusion (NRP) before organ procurement. The aim was to compare outcomes following cDCD LT with NRP and donation after brain death (DBD) LT. Methods. This is a multicenter retrospective study comparing cDCD LT with NRP and DBD LT. A case-matched study (1:2) was performed using the variables such as recipient and donor age, indication of LT. Results. A total of 50 patients from the cDCD group were matched to 100 patients from the DBD group. From postoperative days 1–4, serum transaminase release was significantly lower in the cDCD group compared to the DBD group (P < 0.05). Early allograft dysfunction (cDCD: 18% versus DBD: 32%; P = 0.11), acute kidney injury (26% versus 33%; P = 0.49), 90-d graft loss (2% versus 5%; P = 0.66), and arterial (4% versus 12%; P = 0.19) and biliary (16% versus 17%; P = 0.94) complications were similar between the 2 groups. The 2-y graft survival was 88% for cDCD group and 85% for DBD group (P = 0.91). The 2-y patient survival was 90% for cDCD group and 88% for DBD group (P = 0.68). Conclusions. This study provides evidence that cDCD LT following postmortem NRP can be safely and effectively performed in selected recipients with similar graft and patient survival outcomes, without increased rates of biliary complications and early graft dysfunction compared to DBD LT.

Selective internal radiation therapy combined with concomitant chemotherapy seems a promising strategy as first-line treatment for unresectable intrahepatic cholangiocarcinoma.

Few studies have evaluated the efficacy or the cost of hypothermic oxygenated perfusion (HOPE) in the conservation of extended criteria donor (ECD) grafts from donation after brain death (DBD) donors during liver transplantation (LT). We performed a prospective, monocentric study (NCT03376074) designed to evaluate the interest of HOPE for ECD‐DBD grafts. For comparison, a control group was selected after propensity score matching among patients who received transplants between 2010 and 2017. Between February and November 2018, the HOPE procedure was used in 25 LTs. Immediately after LT, the median aspartate aminotransferase (AST) level was significantly lower in the HOPE group (724UI versus 1284UI; P = 0.046) as were the alanine aminotransferase (ALT; 392UI versus 720UI; P = 0.01), lactate (2.2 versus 2.7; P = 0.01) There was a significant reduction in intensive care unit stay (3 versus 5 days; P = 0.01) and hospitalization (15 versus 20 days; P = 0.01). The incidence of early allograft dysfunction (EAD; 28% versus 42%; P = 0.22) was similar . A level of AST or ALT in perfusate >800UI was found to be highly predictive of EAD occurrence (areas under the curve, 0.92 and 0.91, respectively). The 12‐month graft (88% versus 89.5%; P = 1.00) and patient survival rates (91% versus 91.3%; P = 1.00) were similar. The additional cost of HOPE was estimated at € 5298 per patient. The difference between costs and revenues, from the hospital's perspective, was not different between the HOPE and control groups (respectively, € 3023 versus € 4059]; IC, –€ 5470 and € 8652). HOPE may improve ECD graft function and reduce hospitalization stay without extra cost. These results must be confirmed in a randomized trial.
