Abstract
In colorectal cancer liver metastases (CRLM), the density of tumor-infiltrating lymphocytes, the expression of class I major histocompatibility complex (MHC-I), and the pathological response to preoperative chemotherapy have been associated with oncological outcomes after complete resection. However, the prognostic significance of the heterogeneity of these features in patients with multiple CRLMs remains under investigation. We used a tissue microarray of 220 mismatch repair-gene proficient CRLMs resected in 97 patients followed prospectively to quantify CD3+ T cells and MHC-I by immunohistochemistry. Histopathological response to preoperative chemotherapy was assessed using standard scoring systems. We tested associations between clinical, immunological, and pathological features with oncologic outcomes. Overall, 29 patients (30.2%) had CRLMs homogeneous for CD3+ T cell infiltration and MHC-I. Patients with immune homogeneous compared to heterogeneous CRLMs had longer median time to recurrence (TTR) (30 vs. 12 months, p = .0018) and disease-specific survival (DSS) (not reached vs. 48 months, p = .0009). At 6 years, 80% of the patients with immune homogeneous CRLMs were still alive. Homogeneity of response to preoperative chemotherapy was seen in 60 (61.9%) and 69 (80.2%) patients according to different grading systems and was not associated with TTR or DSS. CD3 and MHC-I heterogeneity was independent of response to pre-operative chemotherapy and of other clinicopathological variables for their association with oncological outcomes. In patients with multiple CRLMs resected with curative intent, similar adaptive immune features seen across metastases could be more informative than pathological response to pre-operative chemotherapy in predicting oncological outcomes.

Abstract
BACKGROUND Neoadjuvant therapy (NT) remains controversial in early-stage pancreatic ductal adenocarcinoma (PDAC), defined as clinical (c)Stage I-II. Our aim was to analyze rates of pathologic upstaging/downstaging for resectable PDAC treated with surgery-first (SF) vs. NT. METHODS Utilizing the National Cancer Data Base (NCDB), patients with cStage I-II PDAC who underwent pancreatoduodenectomy in 2006-2013 were pathologically staged using the AJCC 8th edition and compared by treatment sequencing. RESULTS Among 13,871 patients, 15.3% received NT. Despite higher pre-treatment T-stage (cT2: 71.9% vs. 56.3%, p < 0.001), NT patients had lower rates of pathologic nodal metastases (46.2% vs. 69.2% in SF, p < 0.001), suggesting higher rates of pathologic downstaging. In cStage II, 33.0% were upstaged to stage III after SF, vs. only 14.0% after NT. In cStage I, 65.5% were upstaged following SF, vs. 46.7% after NT (all p < 0.001). Patients with NT (HR-0.77, p < 0.001) or downstaging (HR-0.80, p < 0.001) had improved overall survival (OS). CONCLUSION NT is associated with reduction in unexpected upstaging, reduction in nodal positivity, and improved OS, compared to SF approach in putatively early-stage PDAC. Because clinical staging underestimates the underlying disease burden in resectable PDAC, patients with cStage I-II should be considered for NT.

Abstract
INTRODUCTION Patients with locally advanced pancreatic cancer (LAPC) represent a challenging group to treat, given the involvement of major vascular structures. In selected patients with favorable biology, temporary mesocaval shunt can facilitate the resection and allow for a safer procedure with enhanced exposure to the superior mesenteric vessels. METHODS We present a video of a pancreaticoduodenectomy (PD) with temporary mesocaval shunt with left internal jugular (LIJ) vein conduit. RESULTS A 65-year-old woman presented with LAPC in the uncinate, causing total occlusion of the superior mesenteric vein (SMV) and encasement of the first jejunal artery. After neoadjuvant therapy and evidence of disease stability, a decision was made to perform a PD with a temporary mesocaval shunt to divert mesenteric flow to reduce blood loss and prevent bowel ischemia. During the procedure, the main mesenteric collateral (ileocolic vein) was divided to create the shunt to the inferior vena cava (IVC) with LIJ interposition. The remaining mesenteric tributaries involved by the tumor were divided. The uncinate dissection was performed using a superior mesenteric artery-first approach. Once the resection was completed, the shunt was stapled from the IVC and the graft transposed to the upper SMV. Standard reconstruction was performed. Total operative time was 536 min, and estimated blood loss was 250 cc without transfusions. No perioperative complications occurred. CONCLUSION In selected patients with LAPC, PD with temporary mesocaval shunt can facilitate resection and venous reconstruction in patients with complete portal vein/SMV occlusion.

Abstract
BACKGROUND In patients with stage IV colorectal cancer (CRC), minimally invasive surgery (MIS) may offer optimal oncologic outcome with low morbidity. However, the relative benefit of MIS compared to open surgery in patients requiring multistage resections has not been evaluated. METHODS Patients who underwent totally minimally invasive (TMI) or totally open (TO) resections of CRC primary and liver metastases (CLM) in 2009-2016 were analyzed. Inverse probability of weighted adjustment by propensity score was performed before analyzing risk factors for complications and survival. RESULTS The study included 43 TMI and 121 TO patients. Before and after adjustment, TMI patients had significantly less cumulated postoperative complications (41% vs. 59%, p = 0.001), blood loss (median 100 vs. 200 ml, p = 0.001) and shorter length of hospital stay (median 4.5 vs. 6.0 days, p < 0.001). Multivariate analysis identified TO approach vs. MIS (OR = 2.4, p < 0.001), major liver resection (OR = 4.4, p < 0.001), and multiple CLM (OR = 2.3, p = 0.001) as independent risk factors for complications. 5-year overall survival was comparable (81% vs 68%, p = 0.59). CONCLUSION In patients with CRC undergoing multistage surgical treatment, MIS resection contributes to optimal perioperative outcomes without compromise in oncologic outcomes.

Abstract
BACKGROUND When performing a right hepatectomy, the middle hepatic vein (MHV) should guide the parenchymal transection. MHV hotspots for bleeding can be anticipated when applying the previously developed MHV Roadmap to a minimally invasive approach.1 This video demonstrates application of the MHV Roadmap to perform a safe laparoscopic right hepatectomy. PATIENT A 44-year-old woman with a solitary and large breast cancer liver metastasis in the right liver was considered for a laparoscopic right hepatectomy following an excellent response to neoadjuvant chemotherapy. The MHV anatomy was reconstructed using automated vascular reconstruction software (Synapse, Fuji) ahead of surgery. TECHNIQUE With the patient in the French position, the hilar vessels are exposed and the inflow is controlled. Parenchymal transection begins along the demarcation line.2,3 The constant relationship between the portal bifurcation and the V5 ventral and dorsal allows for easy intraparenchymal identification of the MHV. The parenchymal transection is performed in a convex fashion to optimize exposure of the MHV. Using MHV guidance, the parenchymal transection is continued and V8 is safely identified. The operation is completed with division of the anterior fissure and right hepatic vein. CONCLUSION Outlining the MHV anatomy according to the MHV Roadmap preoperatively helps to anticipate hotspots of bleeding. Guidance along the MHV through the parenchymal transection allows for early identification of tributaries, thereby preventing injury and remnant liver ischemia.

Abstract
Background: Liver metastases present with distinct histopathological growth patterns (HGPs), including the desmoplastic, pushing and replacement HGPs and two rarer HGPs. The HGPs are defined owing to the distinct interface between the cancer cells and the adjacent normal liver parenchyma that is present in each pattern and can be scored from standard haematoxylin-and-eosin-stained (H&E) tissue sections. The current study provides consensus guidelines for scoring these HGPs. Methods: Guidelines for defining the HGPs were established by a large international team. To assess the validity of these guidelines, 12 independent observers scored a set of 159 liver metastases and interobserver variability was measured. In an independent cohort of 374 patients with colorectal liver metastases (CRCLM), the impact of HGPs on overall survival after hepatectomy was determined. Results: Good-to-excellent correlations (intraclass correlation coefficient >0.5) with the gold standard were obtained for the assessment of the replacement HGP and desmoplastic HGP. Overall survival was significantly superior in the desmoplastic HGP subgroup compared with the replacement or pushing HGP subgroup (P=0.006). Conclusions: The current guidelines allow for reproducible determination of liver metastasis HGPs. As HGPs impact overall survival after surgery for CRCLM, they may serve as a novel biomarker for individualised therapies.

Abstract
Portal vein embolization (PVE) can be required to stimulate liver regeneration before hepatectomy for colorectal liver metastasis (CRCLM), however PVE may also trigger CRCLM progression in patients initially exhibiting chemotherapy response. Using RNA-seq, we aimed to determine the molecular networks involved in metastatic progression in this context. A prospective study including all CRCLM patients undergoing PVE prior to hepatectomy was conducted. Paired biopsies of metastatic lesions were obtained prior to and after PVE and total RNA was isolated and used to prepare Illumina rRNA-depleted TruSeq stranded cDNA libraries for HiSeq 100 bp paired-end sequencing. Patients were classified with progression of disease (PDPVE) or stable disease (SDPVE) post-PVE using 3D-CT tumor volumetric analysis. RESULTS Twenty patients were included, 13 (65.0%) in the PDPVE group (median 58.0% (18.6-234.3) increase in tumor volume) and 7 (35.0%) in the SDPVE group exhibiting continuous chemotherapy response (median -14.3% (-40.8 to -2.8) decrease in tumor volume) (p < 0.0001). Our results showed that progressive CRCLM after PVE undergo gene expression changes that indicate activation of core cancer pathways (IL-17 (p = 5.94 × 10-03), PI3K (p = 8.71 × 10-03), IL6 and IGF-1 signaling pathways), consistent with changes driven by cytokines and growth factors. Differential expression analysis in a paired model of progression (EdgeR, DeSeq) identified significantly dysregulated genes in the PDPVE group (FOS, FOSB, RAB20, IRS2). CONCLUSION Differentially expressed genes and pathways with known links to cancer and metastasis were identified post-PVE in patients with disease progression. Highlighting these molecular changes is a crucial first step towards development of targeted therapeutic strategies that may mitigate the effects of PVE on tumor growth.

Abstract
PURPOSE To assess frequency of adverse events, efficacy, and clinical outcomes of percutaneous portal vein embolization (PVE) in patients with bilobar colorectal liver metastases undergoing staged hepatectomy with preservation of segment IV ± I only. MATERIALS AND METHODS Retrospective analysis was performed of 40 consecutive patients who underwent right PVE after successful left lobectomy between 2005 and 2013. Rates of adverse events, future liver remnant (FLR) > 30% compared with baseline liver volume, clinical success (completion of staged hepatectomy with clearance of liver metastases), and overall survival were analyzed. RESULTS PVE was performed using polyvinyl alcohol particles (n = 7; 17.5%), particles plus coils (n = 23; 57.5%), and N-butyl cyanoacrylate glue plus ethiodized oil (n = 10; 25%). Technical success was 100%. After PVE, 20% (n = 8) of patients exhibited portal venous thrombosis, ranging from isolated intrahepatic portal branch thrombosis to massive thrombosis of the main portal vein (n = 3) and responsible for periportal cavernoma and portal hypertension in 5 patients. Of patients, 23 (57.5%) had FLR ≥ 30%, and 21 (52.5%) had clinical success. Six patients had significant stenosis or occlusion of the left portal vein or biliary system after original left lobectomy, which was independently associated with FLR < 30% (R2 = 0.24). Clinical success was the only independent variable associated with survival (R2 = 0.25). CONCLUSIONS PVE for staged hepatectomy with preservation of segment IV ± I only is technically feasible, leading to adequate hypertrophy and clinical success rates in these patients with poor oncologic prognosis. Portal venous thrombosis is greater after the procedure than in the setting of standard PVE.

Abstract
BACKGROUND Driven by disease trends, such as obesity and metabolic syndrome, that are increasingly prevalent in the general population, we aimed to evaluate the comorbidities and attributes of the brain-dead organ donor population over time in a longitudinal study. METHODS We compared overall health and baseline attributes of organ donors between 2000-2005 and 2006-2012 using our prospective transplant database. Descriptive and comparative analyses of the 2 historical cohorts were performed. RESULTS A total of 1040 brain-dead organ donors were included in our analysis: 496 from the 2000-2005 period and 544 from the 2006-2012 period. Our analysis revealed that donors from the recent (2006-2012) period were more likely to have increased body mass index (26.4 ± 6.0 v. 25.0 ± 4.8, p = 0.003), smoking history (57.0% v. 27.2%, p < 0.001), coronary artery disease (14.3% v. 3.2%, p = 0.015) and dyslipidemia (19.1% v. 4.2%, p < 0.001), but less likely to have concurrent infection (1.1% v. 7.9%, p < 0.001) than those from the earlier period. CONCLUSION Our data suggest that the characteristics and comorbidities of brain-dead organ donors have somewhat deteriorated over the last decade. Further studies are needed to evaluate the impact of these health attributes on donated organ utilization and outcomes.

Abstract
BACKGROUND AND AIMS In this pilot study, we assessed the safety and tolerability of combining sorafenib with 90Y radioembolization for the treatment of unresectable hepatocellular carcinoma (hcc). METHODS The study, conducted prospectively during 2009-2012, included eligible patients with unresectable hcc and a life expectancy of at least 12 weeks. Each patient received sorafenib (400 mg twice daily) for 6-8 weeks before 90Y treatment. Safety and tolerability were assessed. RESULTS Of the 40 patients enrolled, 29 completed treatment (combined therapy). In the initial cohort, the most common cause of hcc was hepatitis C (32.5%), and most patients were staged Child A (82.5%). The 29 patients who completed the study had similar baseline characteristics. Grades 1 and 2 toxicities accounted for 77.8% of all adverse events reported. The most common toxicities reported were fatigue (19.0%), alteration in liver function (7.9%), and diarrhea (6.3%). There were 12 grade 3 and 2 grade 4 toxicity events reported. One patient died of liver failure within 30 days after treatment. During the study, the sorafenib dose was reduced in 6 patients (20.7%), and sorafenib had to be interrupted in 4 patients (13.8%) and discontinued in 4 patients (13.8%). The disease control rate was 72.4% per the modified Response Evaluation Criteria in Solid Tumors, and tumour necrosis was observed in 82.8% of patients. Overall survival in patients undergoing combined therapy was 12.4 months. CONCLUSIONS Preliminary results demonstrate the safety and tolerability of combining 90Y radioembolization and sorafenib for advanced hcc. A larger prospective study is needed to determine the extent of the survival benefit.

Abstract
BACKGROUND The impact of renal function recovery on graft survival was examined using estimated glomerular filtration rate (eGFR) slope after kidney transplantation (GAP classification); this was compared to the conventional classification of immediate graft function (IGF), slow graft function (SGF), and delayed graft function (DGF). MATERIALS AND METHODS Overall, 541 cases of cadaveric renal transplants were reviewed from a prospective transplant database. eGFR and its slope were measured using the harmonic mean over the first week post-transplantation. Next, 495 kidney transplant recipients from an independent institution were assessed to determine the prognostic value of graft function based on the eGFR slope. RESULTS The main discrimination of eGFR slopes occurred within the first 7 days. Three groups in the GAP classification (Good graft function, Average graft function, Poor graft function) were defined based on eGFR slope tertiles: good graft function (GGF), average graft function (AGF), and poor graft function (PGF) were defined based on the ΔCrCL per day over the first 7 days: <1 mL/min, 1-4 mL/min, and >4 mL/min, respectively. When applied to the validation cohort, the 5-year graft failure was 20% for the PGF group, 4% for the AGF group, and 3% for the GGF group. Multivariable Cox regression analysis demonstrated better prediction of long-term graft function with the new classification (C statistic 0.49 [old)] vs 0.61 [new]). CONCLUSION The new GAP criteria were better at predicting long-term graft survival and renal function compared to the conventional classification system, and deserve further consideration in future studies.

Abstract
BACKGROUND AND OBJECTIVES Treatment strategies for colorectal cancer liver metastasis (CRCLM) such as major hepatectomy and portal vein embolization (PVE) rely on liver regeneration. We aim to investigate the effect of neoadjuvant chemotherapy on liver regeneration occurring after PVE and after major hepatectomy. METHODS CRCLM patients undergoing PVE or major resection were identified retrospectively from our database. Liver regeneration data (expressed as future liver remnant [FLR] and percentage of liver regeneration [%LR]), total liver volume (TLV) and clinical characteristics were collected. RESULTS Between 2003 and 2013, 226 patients were included (85 major resection, 141 PVE). The median chemotherapy cycles was six in both groups. The median time interval between the last chemotherapy and the intervention was 51 days in the PVE group and 79 days in the hepatectomy group. In the PVE group, chemotherapy was not associated with altered liver regeneration (number of cycles [P = 0.435], timing [P = 0.563], or chemotherapy agent [P = 0.116]). Similarly in the major hepatectomy group, preoperative chemotherapy (number of cycles [P = 0.114]; agent [P = 0.061], timing [P = 0.126]) were not significantly associated with differences in liver regeneration (P = 0.592). In both groups, the predicted FLR% was inversely correlated with the %LR (P < 0.001). CONCLUSION Chemotherapy does not affect liver regeneration following PVE or major resection. J. Surg.

Abstract
Surgical resection of colorectal liver metastases (CRLM) has a well-documented improvement in survival. To benefit from this intervention, proper selection of patients who would be adequate surgical candidates becomes vital. A combination of imaging techniques may be utilized in the detection of the lesions. The criteria for resection are continuously evolving; currently, the requirements that need be met to undergo resection of CRLM are: the anticipation of attaining a negative margin (R0 resection), whilst maintaining an adequate functioning future liver remnant. The timing of hepatectomy in regards to resection of the primary remains controversial; before, after, or simultaneously. This depends mainly on the tumor burden and symptoms from the primary tumor. The role of chemotherapy differs according to the resectability of the liver lesion(s); no evidence of improved survival was shown in patients with resectable disease who received preoperative chemotherapy. Presence of extrahepatic disease in itself is no longer considered a reason to preclude patients from resection of their CRLM, providing limited extra-hepatic disease, although this currently is an area of active investigations. In conclusion, we review the indications, the adequate selection of patients and perioperative factors to be considered for resection of colorectal liver metastasis.

Abstract
BACKGROUND/AIM To elucidate colorectal cancer (CRC) disease patterns, demographics, characteristics, stage at presentation, metastases, and survival rates of patients, particularly those with liver metastases, at our center as the first report from the Kingdom of Saudi Arabia. PATIENTS AND METHODS We performed a retrospective, single-center database study based on the histological diagnosis of CRC in patients seen at the King Khalid University Hospital between 2007 and 2011. RESULTS 427 cases of CRC with a mean age at diagnosis of 55.47 12.85 years, out of which 96% were resected. Stage II was predominant at presentation, followed by both stage III and IV, with the remainder being stage I. One hundred patients had distant metastases, of which the liver was the only location in 54 patients. Mean survival was 3.0 years. Overall survival rates for CRC patients with liver metastases who underwent resection were 30% at 2 years and 17% at 5 years, and the mean survival rate was 1.4 years. CONCLUSIONS Both the mean survival rate of our CRC patients with resectable liver metastases and the 5-year survival rate of these patients are lower than global averages. This discrepancy is likely due to late diagnoses rather than more aggressive disease.

Abstract
Colorectal liver metastasis (CRLM) is the major cause of death in patients diagnosed with colorectal cancer. The gold standard treatment of CRLM is surgical resection. Yet, in the past, more than half of these patients were deemed unresectable due to the inadequate future liver remnant (FLR). The introduction of efficient portal vein embolization (PVE) preoperatively allowed more resections of metastasis in CRLM patients by stimulating adequate liver hypertrophy. However, several experimental and clinical studies reported tumor progression after PVE which critically influences the subsequent management of these patients. The underlying pathophysiological mechanism of tumor progression post-PVE is still not fully understood. In spite of the adverse effects of PVE, it remains a potentially curative procedure in patients who would remain otherwise unresectable because of the insufficient FLR. Currently, the challenge is to halt tumor proliferation following PVE in patients who require this technique. This could potentially be achieved by either attempting to suppress the underlying oncologic stimulus or by inhibiting tumor growth once observed after PVE, without jeopardizing liver regeneration. More research is still required to better identify patients at risk of experiencing tumor growth post-PVE.

Abstract
BACKGROUND The aim of this study was to evaluate the long-term outcomes of patients with colorectal cancer liver metastasis (CRCLM) exhibiting disease progression after portal vein embolization (PVE). METHODS Patients with CRCLM requiring PVE before hepatectomy between 2003 and 2014 were included. Clinical variables, and liver and tumour volumes determined by three-dimensional CT volumetry were assessed before and after PVE. Overall and disease-free survival data were obtained. Univariable and multivariable logistic regression analyses were performed to identify predictors of tumour progression after PVE. RESULTS Of 141 patients who underwent PVE, 93 (66.0 per cent) had tumour progression and 17 (12.1 per cent) developed new contralateral lesions. Significantly fewer patients had resectable disease in the group with disease progression than among those with stable disease: 43 (46 per cent) of 93 versus 36 (75 per cent) of 48 respectively (P = 0.001). Median survival was similar in patients with and without tumour growth after PVE: 22.5 versus 26.0 months for patients with unresectable tumours (P = 0.706) and 46.2 versus 52.2 months for those with resectable disease (P = 0.953). However, disease-free survival for patients with tumour progression after PVE was shorter than that for patients with stable disease (6.0 versus 20.2 months; P = 0.045). Response to neoadjuvant chemotherapy was the only significant factor associated with tumour progression in multivariable analysis. CONCLUSION Tumour progression after PVE did not affect overall survival, but patients with resected tumours who had tumour growth after embolization experienced earlier recurrence. A borderline response to neoadjuvant chemotherapy seemed to be associated with tumour progression after PVE.

Abstract
Severe acute necrotising pancreatitis is associated with numerous local and systemic complications. Abdominal compartment syndrome requiring urgent decompressive laparotomy is a potential complication of this disease process and is associated with increased morbidity and mortality. We describe the case of a pancreaticoatmospheric fistula following decompressive laparotomy in a patient with severe acute necrotising pancreatitis. While this fistula was managed successfully using the current standard of care for pancreatic fistulas, the wound care for in this patient with drainage of the fistula through an open abdomen, is a significant challenge.

Abstract
AIM: To evaluate the ability of the McGill Brisbane Symptom Score (MBSS) to predict survival in resectable pancreatic head adenocarcinoma (PHA) patients.
METHODS: All PHA patients (n = 83) undergoing pancreaticoduodenectomy at the McGill University Health Center, Quebec between 1/2001-1/2010 were evaluated. Data related to patient and cancer characteristics, MBSS variables, and treatment were collected; univariable and multivariable survival analyses were performed. We obtained complete follow-up until February 2011 in all patients through the database of the provincial health insurance plan of Quebec. The unique health insurance numbers of these patients were used to retrieve information from this database which captures all billable clinical encounters, and ensures 100% actual survival data.
RESULTS: Median survival was 23 mo overall: 45 mo for patients with low MBSS, 17 mo for high MBSS (P = 0.005). At twelve months survival was 83.3% (95%CI: 66.6-92.1) vs 58.1% (95%CI: 42.1-71.2) in those with low vs high MBSS, and24 mo survival was 63.8% (95%CI: 45.9-77.1) and 34.0% (95%CI: 20.2-48.2) respectively. In the multivariate Cox model (stratified by chemotherapy), after addition of clinically meaningful covariates, MBSS was the variable with the strongest association with survival (HR = 2.63; P = 0.001). Adjuvant chemotherapy interacted with MBSS category such that only high MBSS patients accrued a benefit. In univariate analysis we found a lower mortality in high MBSS but not low MBSS patients receiving adjuvant chemotherapy. This interaction variable, on Cox model, resulted in an adjusted mortality HR for the high MBSS (compared to low MBSS) of 4.14 (95%CI: 1.48-11.64) without chemotherapy and 2.11 (95%CI: 1.06-4.17) with chemotherapy.
CONCLUSION: The MBSS is a simple prognostic tool for resectable PHA. Preoperative categorization of patients according to the MBSS allows effective stratification of patients to guide therapy.

Abstract
INTRODUCTION We set out to evaluate the prognostic value of (18)F-fluorodeoxyglucose positron-emission tomography (pet) in patients with advanced (non-transplant-eligible) hepatocellular carcinoma (hcc) and to evaluate the correlation between standardized uptake values (suvs) and survival outcomes. METHODS We identified patients with hcc who, from 2005 to 2013, underwent pet imaging before any treatment. This retrospective study from our hcc database obtained complete follow-up data for the 63 identified patients. RESULTS Of the 63 patients, 10 underwent surgical resection, and 59 underwent locoregional therapy. In this cohort, 28 patients were pet-positive (defined as any lesion with a suv ≥ 4.0) before any therapy was given, and 35 patients were pet negative (all lesions with a suv < 4.0). On survival analysis, median survival was greater for the pet-negative than for the pet-positive patients: 29 months (range: 16.3-41.1 months) versus 12 months (range: 4.0-22.1 months) respectively, p = 0.0241. The pet-positive patients more often had large tumours (≥5 cm), poor differentiation, and extrahepatic disease, reflecting more aggressive tumours. On multivariate analysis, only pet positivity was associated with poor survival (p = 0.049). CONCLUSIONS Compared with pet-positive patients, pet-negative patients with hcc experienced longer survival. Imaging by pet can be of value in early prognostication for patients with hcc, especially patients receiving locoregional therapy for whom pathologic tumour differentiation is rarely available. This potential role for pet requires further validation in a prospective study.

Abstract
BACKGROUND Hepatocellular carcinoma (hcc) is one of the most common causes of cancer-related death worldwide. Overall, liver transplantation and resection are the only available treatments with potential for cure. Various locoregional therapies are widely used to manage patients with advanced hcc or as a bridging therapy for patients with early and intermediate disease. This article reviews and evaluates the role of interventional radiology in the management of such cases by assessing various aspects of each method, such as effect on rates of survival, recurrence, tumour response, and complications. METHODS A systemic search of PubMed, medline, Ovid Medline In-Process, and the Cochrane Database of Systematic Reviews retrieved all related scientific papers for review. RESULTS Needle core biopsy is a highly sensitive, specific, and accurate method for hcc grading. Portal-vein embolization provides adequate expansion of the future liver remnant, making more patients eligible for resection. In focal or multifocal unresectable early-stage disease, radiofrequency ablation tops all other thermoablative methods. However, microwave ablation is preferred in large tumours and in patients with Child-Pugh B disease. Cryoablation is preferred in recurrent disease and in patients who are poor candidates for anesthesia. Of the various transarterial modalities-transarterial chemoembolization (tace), drug-eluting beads, and transarterial radio-embolization (tare)-tace is the method of choice in Child-Pugh A disease, and tare is the method of choice in hcc cases with portal vein thrombosis. CONCLUSIONS The existing data support the importance of a multidisciplinary approach in hcc management. Large randomized controlled studies are needed to provide clear indication guidelines for each method.

Abstract
BACKGROUND Downsizing strategies are often attempted for patients with hepatocellular carcinoma (hcc) before liver transplantation (lt). The objective of the present study was to determine clinical predictors of favourable survival outcomes after transarterial chemoembolization (tace) before lt for hcc outside the Milan criteria, so as to better select candidates for this strategy. METHODS In this retrospective study, patients with hcc tumours either beyond Milan criteria (single lesion > 5 cm, 3 lesions with 1 or more > 3 cm) or at the upper limit of Milan criteria (single lesions between 4.1 cm and 5.0 cm), with a predicted waiting time of more than 3 months, received carboplatin-based tace treatments. Exclusion criteria for tace included Child-Pugh C cirrhosis or the presence of portal vein invasion or extrahepatic disease on imaging. Only patients without tumour progression after tace underwent lt. RESULTS Of 160 hcc patients who received liver grafts between 1997 and 2010, 35 were treated with tace preoperatively. The median of the sum of tumour diameters was 6.7 cm (range: 4.8-8.5 cm), which decreased with tace to 5.0 cm (range: 3.3-7.0 cm) at transplantation (p < 0.0004). The percentage drop in alpha-fetoprotein (αfp) was a positive predictor (p = 0.0051) and the time from last tace treatment to transplantation was a negative predictor (p < 0.0001) for overall survival. CONCLUSIONS The percentage drop in αfp and a shorter time from the final tace treatment to transplantation significantly predicted improved overall survival after lt for hcc downsized with tace. As a serum marker, αfp should be followed when tace is used as a strategy to stabilize or downsize hcc lesions before lt.

Abstract
OBJECTIVES This study describes the management of patients with bilobar colorectal liver metastases (CRLM). METHODS A retrospective collection of data on all patients with CRLM who were considered for staged resection (n= 85) from January 2003 to January 2011 was performed. Patients who underwent one hepatic resection were considered to have had a failed staged resection (FSR), whereas those who underwent a second or third hepatic resection to produce a cure were considered to have had a successful staged resection (SSR). Survival was calculated from the date of diagnosis of liver metastases. Complete follow-up and dates of death were obtained from the Government of Quebec population database. RESULTS Median survival was 46 months (range: 30-62 months) in the SSR group and 22 months (range: 19-29 months) in the FSR group. Rates of 5-year survival were 42% and 4% in the SSR and FSR groups, respectively. Fifteen of the 19 patients who remained alive at the last follow-up date belonged to the SSR group. CONCLUSIONS In patients in whom staged resection for bilobar CRLM is feasible, surgery would appear to offer benefit.

Abstract
OBJECTIVES Portal vein embolization (PVE) can facilitate the resection of previously unresectable colorectal cancer (CRC) liver metastases. Bevacizumab is being used increasingly in the treatment of metastatic CRC, although data regarding its effect on post-embolization liver regeneration and tumour growth are conflicting. The objective of this observational study was to assess the impact of pre-embolization bevacizumab on liver hypertrophy and tumour growth. METHODS Computed tomography scans before and 4 weeks after PVE were evaluated in patients who received perioperative chemotherapy with or without bevacizumab. Scans were compared with scans obtained in a control group in which no PVE was administered. Future liver remnant (FLR), total liver volume (TLV) and total tumour volume (TTV) were measured. Bevacizumab was discontinued ≥ 4 weeks before PVE. RESULTS A total of 109 patients and 11 control patients were included. Portal vein embolization induced a significant increase in TTV: the right lobe increased by 33.4% in PVE subjects but decreased by 34.8% in control subjects (P < 0.001), and the left lobe increased by 49.9% in PVE subjects and decreased by 33.2% in controls (P= 0.022). A total of 52.8% of the study group received bevacizumab and 47.2% did not. There was no statistical difference between the two chemotherapy groups in terms of tumour growth. Median FLR after PVE was similar in both groups (28.8% vs. 28.7%; P= 0.825). CONCLUSIONS Adequate liver regeneration was achieved in patients who underwent PVE. However, significant tumour progression was also observed post-embolization.

Abstract
BACKGROUND Neuroendocrine tumours (NET) frequently metastasize to the liver. NET liver metastasis has been shown to respond to Yttrium-90 microspheres therapy. The aims of the present study were to define factors that predict the response to radio-embolization in patients with NET liver metastases. METHODS From January 2006 until March 2009, all patients with NET liver metastasis that received radio-embolization using TheraSphere® (glass microspheres) were reviewed. The response was determined by a change in the percentage of necrosis (ΔN%) after the first radio-embolization based on the modified RECIST criteria (mRECIST) criteria. The following confounding variables were measured: age, gender, size of the lesions, liver involvement, World Health Organization (WHO) classification, the presence of extra-hepatic metastasis, octereotide treatment and previous operative [surgery and (RFA)] and non-operative treatments (chemo-embolization and bland-embolization). RESULTS In all, 25 patients were identified, with a median follow-up of 21.7 months. The median age was 64.6 years, 28% had extra-hepatic metastasis and 56% were WHO stage 2. Post-treatment, the mean ΔN% was 48.4%. Previous surgical therapy was a significant predictor of the response with a response rate of 66.7 ΔN% vs. 31.5 ΔN% (P= 0.02). Bilateral liver disease, a high percentage of liver involvement and large metastatic lesions were inversely related to the degree of tumour response although did not reach statistical significance. CONCLUSION Radio-embolization increased the necrosis of NET liver metastasis mainly in patients with less bulky disease. This may imply that surgical therapy before radio-embolization would increase the response rates.

Abstract
BACKGROUND This study attempts to define clinical predictors of survival in patients with unresectable pancreatic adenocarcinoma (UPA). METHODS A retrospective study of 94 consecutive patients diagnosed with UPA from 2001 to 2006 was performed. Using data for these patients, a symptom score was devised through a forward stepwise Cox proportional hazards model based on four weighted criteria: weight loss of >10% of body weight; pain; jaundice, and smoking. The symptom score was subsequently validated in a distinct cohort of 32 patients diagnosed with UPA in 2007. RESULTS In the original cohort, the overall median survival was 9.0 months (95% confidence interval [CI] 7.6-10.4). This altered to 10.3 months (95% CI 6.1-14.5) in patients with locally advanced disease, and 6.6 months (95% CI 4.2-9.0) in patients with distant metastasis. Median survival was 14.6 months (95% CI 13.1-16.1) in patients with a low symptom (LS) score and 6.3 months (95% CI 4.1-8.5) in patients with a high symptom (HS) score. A total of 73% of LS score patients survived beyond 9 months, compared with only 38% of HS score patients (P<0.001). The discrimination of the LS score was greater than that of any conventional method, including imaging. The validation cohort confirmed the discriminative ability of the symptom score for survival. CONCLUSIONS A simple and clinically meaningful point-based symptom score can successfully predict survival in patients with UPA.

Abstract
Hematopoietic stem cell (HSC) transplantation is the most frequent underlying predisposing condition to invasive aspergillosis. However, the significance of positive blood culture with Aspergillus sp in this particular population remains uncertain. We retrospectively reviewed all blood cultures performed in 1453 patients who received HSC transplant at our institution between 1980 and 2002. We identified 19 patients with positive blood cultures with Aspergillus sp. Only one of these patients had clinical, histologic or microbiologic evidence of invasive aspergillosis. Thus, even in a population at highest risk for invasive aspergillosis, positive blood cultures with Aspergillus sp remain unusual, and cannot be readily associated with invasive aspergillosis. A case by case assessment by treating physicians of the clinical and radiologic parameters should be systematically made to establish the significance of aspergillemia. Single bottle positivity, obtained with the lysis-centrifugation blood culture system, is a common indicator of pseudoaspergillemia.

Abstract
Newark, a metropolitan industrial town, experienced the highest infant mortality of any major city in the United States in the 1960s and early 1970s. Between 1970 and 1973, however, infant mortality among non-whites in this city declined strikingly. This decline could not be directly related to declines (a) in birth rates, (b) in the proportions of babies of low birth weight, (c) in the proportions of babies born to mothers in unfavorable age groups, (d) in the general fertility rates, or (e) in the illegitimacy rates. The decline may have been related (a) to the removal from childbearing cohorts of the group of females in the population--as yet undefined--whose babies would have been at high risk of infant mortality, (b) to the falling birth rate, (d) to better postnatal care--or to all of these factors. The study data suggest a multifactorial basis for the precipitous decline and also suggest that further major reductions in infant mortality among both nonwhites and whites will require better definition of the causes of low birth weight.
