Abstract
Background Metastatic colorectal cancer frequently occurs in elderly patients. Bevacizumab in combination with front line chemotherapy (CT) is a standard treatment but some concern raised about tolerance of bevacizumab for these patients. The purpose of PRODIGE 20 was to evaluate tolerance and efficacy of bevacizumab according to specific end points in this population. Patients and methods Patients aged 75 years and over were randomly assigned to bevacizumab + CT (BEV) versus CT. LV5FU2, FOLFOX and FOLFIRI regimen were prescribed according to investigator’s choice. The composite co-primary end point, assessed 4 months after randomization, was based on efficacy (tumor control and absence of decrease of the Spitzer QoL index) and safety (absence of severe cardiovascular toxicities and unexpected hospitalization). For each arm, the treatment will be consider as inefficient if 20% or less of the patients met the efficacy criteria and not safe if 40% or less met the safety criteria. Results About 102 patients were randomized (51 BEV and 51 CT), median age was 80 years (range 75–91). Primary end point was met for efficacy in 50% and 58% and for safety in 61% and 71% of patients in BEV and CT, respectively. Median progression-free survival was 9.7 months in BEV and 7.8 months in CT. Median overall survival was 21.7 months in BEV and 19.8 months in CT. The 36-month overall survival rate was 27% in BEV and 10.1% in CT. Severe toxicities grade 3/4 were mainly non-hematologic toxicities (80.4% in BEV, 63.3% in CT). Conclusion Bevacizumab combined with CT was safe and efficient. Both arms met the primary safety and efficacy criteria.

Abstract
INTRODUCTION The clinical benefit of double-front-line therapy (including oxaliplatin or irinotecan or bevacizumab plus 5-fluorouracil (5FU) or capecitabine) compared to monotherapy (5FU or capecitabine) in elderly (> 70 years) patients with metastatic colorectal cancer (MCRC) is controversial. We performed a meta-analysis of published randomized studies. MATERIALS AND METHODS The selection of the studies was carried out using PubMed with the following keywords: "metastatic colorectal cancer," "elderly," "oxaliplatin," "irinotecan," "bevacizumab," "survival." The efficacy endpoints were overall survival (OS) and progression-free survival (PFS). Hazard ratios (HRs) with their 95% confidence intervals (CIs) were collected from the studies and pooled. By convention, an HR < 1 was a result in favor of biotherapy. RESULTS This meta-analysis (MA) included ten studies: three assessing irinotecan (FFCD 2001-02, CAIRO, and an already published MA by Folprecht), three assessing oxaliplatin (FOCUS2, FFCD 2000-05, and a published study by De Gramont), and four assessing bevacizumab (PRODIGE-20, AVEX, AGITG-MAX, and "AVF2192g" by Kabbinavar). Our MA included 1652 patients (62% of men). Concerning age, we chose a cut-off of 70 years or a cut-off of 75 years, corresponding to the available data for each study. The performance index (PS) was 0-1 for about 90% of patients, with the exception of FFCD 2001-02 and FOCUS2 which included 30% of patients with PS2. Overall, the addition of bevacizumab to fluoropyrimidin statistically improves both OS and PFS (HR = 0.78; CI 0.63-0.96 and HR = 0.55; CI 0.44-0.67, respectively). The addition of oxaliplatin did not statistically improve OS (= 0.99; CI 0.85-1.17) but improves PFS (HR = 0.81; CI 0.67-0.97) as well as the addition of irinotecan (HR = 1.01; CI 0.84-1.22 and HR = 0.82; CI 0.68-1.00, respectively). CONCLUSION In previously untreated elderly patients with MCRC, the addition of bevacizumab to fluoropyrimidin appears more effective in terms of OS or PFS than the addition of oxaliplatin or irinotecan.

Abstract
Oxaliplatin-based adjuvant chemotherapy is standard of care for radically resected stage III colon cancer and an accepted option for high-risk stage II. Two recent retrospective studies strongly suggested that low-dose aspirin used (100 mg/d) after surgical resection of colorectal cancer with a PIK3CA mutation could act as a targeted therapy with a major protective effect on the risk of recurrence. We propose a double-blind randomized phase III study to evaluate aspirin (100 mg/d during 3 years or until recurrence) versus placebo. Main inclusion criteria are patients aged 18 or 20, stage III or high risk stage II. The primary endpoint of the study is 3-year disease-free survival (DFS). Hypotheses are to improve 3-years DFS from placebo: 72% to aspirin: 83% (HR = 0.56). 94 events and 264 patients with PIK3CA mutation are required. The secondary endpoints are DFS at 5 years, the overall survival rate at 5 years, grade 3-4 severe bleeding.

Abstract
TPS3628 Background: Colon cancer (CC) occurs in around 50% of the patients after 70 years. Adjuvant chemotherapy (CT) has demonstrated a benefit on disease-free survival (DFS) and overall survival after a stage III CC resection. Nevertheless, adjuvant CT is poorly used in elderly patients. There is still concern about the efficacy of doublet CT with oxaliplatin in fit elderly patients and the usefulness of fluoropyrimidine monotherapy in unfit elderly patients. The selection of patients that should be treated remains a challenge. Geriatric evaluation and tumor biology should be explored to help for patient selection. Methods: ADAGE is a multicenter, randomized phase III study comparing 3-years DFS of 2 therapeutic strategies in 2 groups of patients aged over 70 with completely resected stage III CC. Patients are included in one of the 2 groups after a multidisciplinary team evaluation; Group 1 (arm A and B) is defined as “able” to be treated with doublet CT; Group 2 (arm C and D) is defined as “unable” to be treated with doublet CT. In each group, patients are randomized according to a 1:1 ratio. Randomization is stratified according to center, gender, stage (IIIA vs IIIB vs IIIC), occlusion and/or perforation (yes vs no) and independent activity of daily living score (IADL: normal vs abnormal). Arm A and D receive LV5FU2 or capecitabine, arm B FOLFOX4 or XELOX and arm C is an observation arm. The treatment is planned for 6 months. Adjuvant CT should start within 12 weeks after surgery. Geriatric questionnaires and Lee score must be completed before randomization. Radiological assessment is performed every 6 months for 3 years after randomization and then annually for 2 years. Hypotheses (α two-sided = 5%, power = 80%) are to improve 3-years DFS from 65% (arm A) to 72% (arm B) in group 1 (756 patients required) and from 40% (arm C) to 55% (arm D) in group 2 (226 patients required). Safety is evaluated based on laboratory and clinical tests before each cycle. Exploratory analysis are planned to determine geriatric prognostic factors for DFS. A biological ancillary study is planned to allow prognostic evaluation of mismatch repair status and other molecular signatures. At the 1stof February 2017 the accrual was 246 patients. Clinical trial information: NCT02355379.

Abstract
3550 Background: In the early 2000s, classic LV5FU2 (C) (folinic acid, 5FU bolus, then 5FU infusion on D1 and D2) was replaced with simplified LV5FU2 (S) (folinic acid and 5FU bolus on D1 only), considered as effective and less toxic. No trial proved this assertion. The LV5FU2 companion in the FOLFIRI or FOLFOX regimen was C or S. The FFCD 2001-02 study compared in a 2 x 2 factorial design, in not-pretreated elderly patients (75+) with metastatic colorectal cancer, C or S, with or without irinotecan. No significant differences in PFS and OS were observed in the comparison with or without irinotecan. The median OS was 15.2 months in C versus 11.4 months in S, HR = 0.71 (0.55–0.92) and objective response rate was 37.1% in C vs S 25.6% in S, p = 0.004. The aim of this study was to present the factors associated with these differences. Methods: Prognostic factors associated with OS were studied using a Cox model. The multivariate analysis used the significantly different items from the univariate analysis and the differences observed at the inclusion. For each of these items, a subgroup analysis was performed. The second- and third-line treatments were analysed. Results: The 282 patients from the intent-to-treat study were included in the model. In OS, the prognostic factors were C versus S, number of metastatic sites, alkaline phosphatases (AP) and CEA. The interaction test in each subgroup for OS was not significant but C was significantly better in the following subgroup: age > 80 years, male, Karnofsky 100%, 1-2 Charlson index, AP ≤ 2N, leucocyte count > 11,000, CEA > 2N, CA 19-9 ≤2N. No differences were observed in the NCI toxicities but 130 serious adverse events in S versus 102 in C. A second-line was used for 55% patients in C, 46% in S, 81% of them with oxaliplatin or irinotecan in C, 76% after S. The third-line administration (20%) and targeted therapy (15%) were similar in C and S. Conclusions: C-LV5FU2 was superior both in subgroups with better and lower prognostics and this difference cannot be explained by an imbalance between the populations. The toxicity was not higher and a second-line was more often possible after C. The switch from C to S without scientific proof was perhaps a mistake in our practices. Clinical trial information: NCT00303771.

Abstract
Clinical islet transplantation achieves insulin independence in selected patients, yet current methods for extracting islets from their surrounding pancreatic matrix are suboptimal. The islet basement membrane (BM) influences islet function and survival and is a critical marker of islet integrity following rodent islet isolation. No studies have investigated the impact of islet isolation on BM integrity in human islets, which have a unique duplex structure. To address this, samples were taken from 27 clinical human islet isolations (donor age 41-59, BMI 26-38, cold ischemic time < 10 h). Collagen IV, pan-laminin, perlecan and laminin-α5 in the islet BM were significantly digested by enzyme treatment. In isolated islets, laminin-α5 (found in both layers of the duplex BM) and perlecan were lost entirely, with no restoration evident during culture. Collagen IV and pan-laminin were present in the disorganized BM of isolated islets, yet a significant reduction in pan-laminin was seen during the initial 24 h culture period. Islet cytotoxicity increased during culture. Therefore, the human islet BM is substantially disrupted during the islet isolation procedure. Islet function and survival may be compromised as a consequence of an incomplete islet BM, which has implications for islet survival and transplanted graft longevity.

Abstract
Background and Purpose Liraglutide improves the metabolic control of diabetic animals after islet transplantation. However, the mechanisms underlying this effect remain unknown. The objective of this study was to evaluate the anti‐inflammatory and anti‐oxidative properties of liraglutide on rat pancreatic islets in vitro and in vivo. Experimental Approach In vitro, rat islets were incubated with 10 μmol·L−1 liraglutide for 12 and 24 h. Islet viability functionality was assessed. The anti‐inflammatory properties of liraglutide were evaluated by measuring CCL2, IL‐6 and IL‐10 secretion and macrophage chemotaxis. The anti‐oxidative effect of liraglutide was evaluated by measuring intracellular ROS and the total anti‐oxidative capacity. In vivo, 1000 islets were cultured for 24 h with or without liraglutide and then transplanted into the liver of streptozotocin‐induced diabetic Lewis rats with or without injections of liraglutide. Effects of liraglutide on metabolic control were evaluated for 1 month. Key Results Islet viability and function were preserved and enhanced with liraglutide treatment. Liraglutide decreased CCL2 and IL‐6 secretion and macrophage activation after 12 h of culture, while IL‐10 secretion was unchanged. However, intracellular levels of ROS were increased with liraglutide treatment at 12 h. This result was correlated with an increase of anti‐oxidative capacity. In vivo, liraglutide decreased macrophage infiltration and reduced fasting blood glucose in transplanted rats. Conclusions and Implications The beneficial effects of liraglutide on pancreatic islets appear to be linked to its anti‐inflammatory and anti‐oxidative properties. These findings indicated that analogues of glucagon‐like peptide‐1 could be used to improve graft survival.

Abstract
In bioartificial pancreases (BP), the number of islets needed to restore normoglycaemia in the diabetic patient is critical. However, the confinement of a high quantity of islets in a limited space may impact islet survival, particularly in regard to the low oxygen partial pressure (PO2) in such environments. The aim of the present study was to evaluate the impact of islet number in a confined space under hypoxia on cell survival. Rat islets were seeded at three different concentrations (150, 300, and 600 Islet Equivalents (IEQ)/cm(2)) and cultured in normal atmospheric pressure (160 mmHg) as well as hypoxic conditions (15 mmHg) for 24 hours. Cell viability, function, hypoxia-induced changes in gene expression, and cytokine secretion were then assessed. Notably, hypoxia appeared to induce a decrease in viability and increasing islet density exacerbated the observed increase in cellular apoptosis as well as the loss of function. These changes were also associated with an increase in inflammatory gene transcription. Taken together, these data indicate that when a high number of islets are confined to a small space under hypoxia, cell viability and function are significantly impacted. Thus, in order to improve islet survival in this environment during transplantation, oxygenation is of critical importance.

Abstract
Exogenous insulin is the only treatment available for type 1 diabetic patients and is mostly administered by subcutaneous (SC) injection in a basal and bolus scheme using insulin pens (injection) or pumps (preimplanted SC catheter). Some divergence exists between these two modes of administration, since pumps provide better glycaemic control compared to injections in humans. The aim of this study was to compare the impacts of two modes of insulin administration (single injections of long-acting insulin or pump delivery of rapid-acting insulin) at the same dosage (4 IU/200 g/day) on rat metabolism and tissues. The rat weight and blood glucose levels were measured periodically after treatment. Immunostaining for signs of oxidative stress and for macrophages was performed on the liver and omental tissues. The continuous insulin delivery by pumps restored normoglycaemia, which induced the reduction of both reactive oxygen species and macrophage infiltration into the liver and omentum. Injections controlled the glucose levels for only a short period of time and therefore tissue stress and inflammation were elevated. In conclusion, the insulin administration mode has a crucial impact on rat metabolic parameters, which has to be taken into account when studies are designed.

Abstract
High-dose FOLFIRI has an acceptable safety profile and promising efficacy. UDP-glucuronosyltransferase: (UGT1A1) polymorphism may be predictive of toxicity and efficacy of irinotecan. This phase II study aimed to evaluate the combination of high-dose FOLFIRI plus bevacizumab in patients with previously untreated metastatic colorectal cancer (MCRC) based on their UGT1A1 genotype. Patients with the UGT1A1 *1/*1 (group 1) or *1/*28 (group 2) genotype received bevacizumab plus high-dose FOLFIRI every 2 weeks. Using the Bryant and Day design with objective response rate and toxicity as the primary endpoints, 54 patients in each group were required with a planned interim analysis after inclusion of 17 patients per group. We planned to stop the trial at the interim analysis if ≤ 7 patients exhibited an objective response (OR) and/or ≥ 3 patients exhibited severe toxicity. At the interim analysis, ORs were higher than the number expected: 52.9% (group 1) and 58.8% (group 2). More than three toxic events occurred in both groups and, according to the interim analysis rule, the trial was closed due to unacceptable toxicity. Recruitment was stopped when 86 patients were included and an analysis on overall population was done for overall survival (OS) and progression-free survival (PFS). The median PFS was 10.7 months (group 1) and 10.4 months (group 2). The median OS was 25.5 months (group 1) and 23.9 months (group 2). This trial does not support the use of the intensive treatment with HD-FOLFIRI plus bevacizumab combination for MCRC in patients with the UGTA1*1/UGT1A1*1 or UGT1A1*1/UGT1A1*28 genotype.

Abstract
BACKGROUND Metastatic colorectal cancer (mCRC) frequently occurs in elderly patients. However, data from a geriatric tailored randomized trial about tolerance to and the efficacy of doublet chemotherapy (CT) with irinotecan in the elderly are lacking. The benefit of first-line CT intensification remains an issue in elderly patients. PATIENTS AND METHODS Elderly patients (75+) with previously untreated mCRC were randomly assigned in a 2 × 2 factorial design (four arms) to receive 5-FU (5-fluorouracil)-based CT, either alone (FU: LV5FU2 or simplified LV5FU2) or in combination with irinotecan [IRI: LV5FU2-irinotecan or simplified LV5FU2-irinotecan (FOLFIRI)]. The CLASSIC arm was defined as LV5FU2 or LV5FU2-irinotecan and the SIMPLIFIED arm as simplified LV5FU2 or FOLFIRI. The primary end point was progression-free survival (PFS). Secondary end points were overall survival (OS), safety and objective response rate (ORR). RESULTS From June 2003 to May 2010, 71 patients were randomly assigned to LV5FU2, 71 to simplified LV5FU2, 70 to LV5FU2-irinotecan and 70 to FOLFIRI. The median age was 80 years (range 75-92 years). No significant difference was observed for the median PFS: FU 5.2 months versus IRI 7.3 months, hazard ratio (HR) = 0.84 (0.66-1.07), P = 0.15 and CLASSIC 6.5 months versus SIMPLIFIED 6.0 months, HR = 0.85 (0.67-1.09), P = 0.19. The ORR was superior in IRI (P = 0.0003): FU 21.1% versus IRI 41.7% and in CLASSIC (P = 0.04): CLASSIC 37.1% versus SIMPLIFIED 25.6%. Median OS was 14.2 months in FU versus 13.3 months in IRI, HR = 0.96 (0.75-1.24) and 15.2 months in CLASSIC versus 11.4 months in SIMPLIFIED, HR = 0.71 (0.55-0.92). More patients presented grade 3-4 toxicities in IRI (52.2% versus 76.3%). CONCLUSION In this elderly population, adding irinotecan to an infusional 5-FU-based CT did not significantly increase either PFS or OS. Classic LV5FU2 was associated with an improved OS compared with simplified LV5FU2. CLINICALTRIALSGOV NCT00303771.

Abstract
Disruption of the pancreatic islet environment combined with the decrease in oxygen supply that occurs during isolation leads to poor islet survival. The aim of this study was to validate the benefit of using a plasma-based scaffold supplemented with perfluorodecalin to improve islet transplantation outcome. Rat islets were cultured in three conditions: i) control group, ii) plasma based-matrix (P-matrix), and iii) P-matrix supplemented with emulsified perfluorodecalin. After 24 h culture, matrix/cell contacts (Integrinβ1, p-FAK/FAK, p-Akt/Akt), survival (caspase 3, TUNEL, FDA/PI), function, and HIF-1α translocation were assessed. Afterwards, P-matrices were dissolved and the islets were intraportally transplanted. Graft function was monitored for 31 days with glycaemia and C-peptide follow up. Inflammation was assessed by histology (macrophage and granulocyte staining) and thrombin/anti-thrombin complex measurement. Islet survival correlated with an increase in integrin, FAK, and Akt activation in P-matrices and function was maintained. Perfluorodecalin supplementation decreased translocation of HIF-1α in the nucleus and post-transplantation islet structure was better preserved in P-matrices, but a quicker activation of IBMIR resulted in early loss of graft function. "Oxygenating" P-matrices provided a real benefit to islet survival and resistance in vivo. However, intraportal transplantation is not suitable for this kind of culture due to IBMIR; thus, alternative sites must be explored.

Abstract
Knowledge of wetland bacterial communities in the context of pesticide contamination and hydrological regime is scarce. We investigated the bacterial composition in constructed wetlands receiving Mercantor Gold(®) contaminated water (960 g L(-1) of the herbicide S-metolachlor, >80% of the S-enantiomer) operated under continuous-flow or batch modes to evaluate the impact of the hydraulic regime. In the continuous-flow wetland, S-metolachlor mass removal was >40%, whereas in the batch wetland, almost complete removal of S-metolachlor (93-97%) was observed. Detection of ethanesulfonic and oxanilic acid degradation products further indicated S-metolachlor biodegradation in the two wetlands. The dominant bacterial populations were characterised by terminal restriction fragment length polymorphism (T-RFLP) and 454 pyrosequencing. The bacterial profiles evolved during the first 35 days of the experiment, starting from a composition similar to that of inlet water, with the use of nitrate and to a lesser extent sulphate and manganese as terminal electron acceptors for microbial metabolism. Proteobacteria were the most abundant phylum, with Beta-, Alpha- and Gammaproteobacteria representing 26%, 19% and 17% respectively of total bacterial abundance. Bacterial composition in wetland water changed gradually over time in continuous-flow wetland and more abruptly in the batch wetland. Differences in overall bacterial water structure in the two systems were modest but significant (p=0.008), and S-metolachlor, nitrate, and total inorganic carbon concentrations correlated with changes in the bacterial profiles. Together, the results highlight that bacterial composition profiles and their dynamics may be used as bioindicators of herbicide exposure and hydraulic disturbances in wetland systems.

Abstract
Purpose To compare epirubicin, cisplatin, and capecitabine (ECX) with fluorouracil, leucovorin, and irinotecan (FOLFIRI) as first-line treatments in patients with advanced gastric or esophagogastric junction (EGJ) adenocarcinoma. Patients and Methods This open, randomized, phase III study was carried out in 71 centers. Patients with locally advanced or metastatic gastric or EGJ cancer were randomly assigned to receive either ECX as first-line treatment (ECX arm) or FOLFIRI (FOLFIRI arm). Second-line treatment was predefined (FOLFIRI for the ECX arm and ECX for the FOLFIRI arm). The primary criterion was time-to-treatment failure (TTF) of the first-line therapy. Secondary criteria were progression-free survival (PFS), overall survival (OS), toxicity, and quality of life. Results In all, 416 patients were included (median age, 61.4 years; 74% male). After a median follow-up of 31 months, median TTF was significantly longer with FOLFIRI than with ECX (5.1 v 4.2 months; P = .008). There was no significant difference between the two groups in median PFS (5.3 v 5.8 months; P = .96), median OS (9.5 v 9.7 months; P = .95), or response rate (39.2% v 37.8%). First-line FOLFIRI was better tolerated (overall rate of grade 3 to 4 toxicity, 69% v 84%; P < .001; hematologic adverse events [AEs], 38% v 64.5%; P < .001; nonhematologic AEs: 53% v 53.5%; P = .81). Conclusion FOLFIRI as first-line treatment for advanced gastric and EGJ cancer demonstrated significantly better TTF than did ECX. Other outcome results indicate that FOLFIRI is an acceptable first-line regimen in this setting and should be explored as a backbone regimen for targeted agents.

Abstract
PURPOSE Although often investigated in locally advanced esophageal cancer (EC), the impact of neoadjuvant chemoradiotherapy (NCRT) in early stages is unknown. The aim of this multicenter randomized phase III trial was to assess whether NCRT improves outcomes for patients with stage I or II EC. METHODS The primary end point was overall survival. Secondary end points were disease-free survival, postoperative morbidity, in-hospital mortality, R0 resection rate, and prognostic factor identification. From June 2000 to June 2009, 195 patients in 30 centers were randomly assigned to surgery alone (group S; n = 97) or NCRT followed by surgery (group CRT; n = 98). CRT protocol was 45 Gy in 25 fractions over 5 weeks with two courses of concomitant chemotherapy composed of fluorouracil 800 mg/m(2) and cisplatin 75 mg/m(2). We report the long-term results of the final analysis, after a median follow-up of 93.6 months. RESULTS Pretreatment disease was stage I in 19.0%, IIA in 53.3%, and IIB in 27.7% of patients. For group CRT compared with group S, R0 resection rate was 93.8% versus 92.1% (P = .749), with 3-year overall survival rate of 47.5% versus 53.0% (hazard ratio [HR], 0.99; 95% CI, 0.69 to 1.40; P = .94) and postoperative mortality rate of 11.1% versus 3.4% (P = .049), respectively. Because interim analysis of the primary end point revealed an improbability of demonstrating the superiority of either treatment arm (HR, 1.09; 95% CI, 0.75 to 1.59; P = .66), the trial was stopped for anticipated futility. CONCLUSION Compared with surgery alone, NCRT with cisplatin plus fluorouracil does not improve R0 resection rate or survival but enhances postoperative mortality in patients with stage I or II EC.

Abstract
Compound-specific isotope analysis (CSIA) is a promising tool to study the environmental fate of a wide range of contaminants including pesticides. In this study, a novel CSIA method was developed to analyse the stable carbon isotope signatures of widely used chloroacetanilide herbicides. The developed method was applied in combination with herbicide concentration and hydrochemical analyses to investigate in situ biodegradation of metolachlor, acetochlor and alachlor during their transport in lab-scale wetlands. Two distinct redox zones were identified in the wetlands. Oxic conditions prevailed close to the inlet of the four wetlands (oxygen concentration of 212±24μM), and anoxic conditions (oxygen concentrations of 28±41μM) prevailed towards the outlet, where dissipation of herbicides mainly occurred. Removal of acetochlor and alachlor from inlet to outlet of wetlands was 56% and 51%, whereas metolachlor was more persistent (23% of load dissipation). CSIA of chloroacetanilides at the inlet and outlet of the wetlands revealed carbon isotope fractionation of alachlor (εbulk=-2.0±0.3‰) and acetochlor (εbulk=-3.4±0.5‰), indicating that biodegradation contributes to the dissipation of both herbicides. This study is a first step towards the application of CSIA to evaluate the transport and degradation of chloroacetanilide herbicides in the environment.

Abstract
BACKGROUND For resectable gastric cancer, both postoperative chemoradiotherapy and perioperative chemotherapy demonstrate high-level evidence for improved survival in Western populations. To evaluate the feasibility of pre- or postoperative chemoradiotherapy, we proposed two multicentre phase II studies. PATIENTS AND METHODS Patients with localised, histologically confirmed gastric cancer and Eastern Cooperative Oncology Group (ECOG) performance status <2 judged suitable for curative resection were eligible. Eligible patients were assigned to either preoperative chemoradiotherapy followed by surgical resection or surgical resection followed by chemoradiotherapy depending on each centre. Chemoradiotherapy regimen included four courses of FOLFIRI (5 Fluorouracil, Leucovorin, Irinotecan) regimen then Concurrent fluorouracil at 200 mg/m2/d by continuous infusion 5 days each week. A dose of 50 Gy in 25 fractions in the preoperative study, or 45 Gy in 25 fractions in the postoperative study, was delivered. The primary end-point for both studies was the proportion of patients, who completed the therapeutic sequence. RESULTS Between September 2007 and January 2010, 63 patients were included in both studies. The postoperative study was stopped for futility at the first step. In the preoperative study, 31 patients (73.8%, confidence interval (CI) 95%: 65.8-90.1%) received complete therapeutic sequence. Serum albumin and dietary restriction evaluated by QLQ-STO22 (Quality of Life-Stomach module) score were significantly linked with chemoradiotherapy feasibility in univariate analysis with respectively Odds-ratio (OR) 1.16 [CI 95%: 1.01-1.33] and 0.17 [0.03-0.89], p=0.04. Median overall survival time was 26.4 months in the preoperative study. CONCLUSION Feasibility of chemoradiotherapy was not achieved for these studies: 73.8% (CI 95%: 65.8-90.1) and 42.9% (CI 95%: 21.8-66%) in preoperative and postoperative settings respectively.

Abstract
As oxygen carriers, perfluorocarbon emulsions might be useful to decrease hypoxia of pancreatic islets before transplantation. However, their hydrophobicity prevents their homogenisation in culture medium. To increase the surface of contact between islets and Perfluorooctyl bromide (PFOB), and consequently oxygen delivery, we tested effect of a PFOB emulsion in culture medium on β-cell lines and rat pancreatic islets. RINm5F β-cell line or pancreatic rat islets were incubated for 3 days in the presence of PFOB emulsion in media (3.5% w/v). Preoxygenation of the medium was performed before culture. Cell viability was assessed by apoptotic markers (Bax and Bcl-2) and by staining (fluoresceine diacetate and propidium iodide). β-Cell functionality was determined by insulin release during a glucose stimulation test and. Hypoxia markers, HIF-1α and VEGF, were studied at days 1 and 3 using RT-PCR, Western blotting, and ELISA. PFOB emulsions preserved viability and functionality of RINm5F cells with a decrease of HIF-1α and VEGF expression. Islets viability was preserved during 3 days of culture. Secretion of VEGF was higher in untreated control (0.09 ± 0.041 μg VEGF/mg total protein) than in PFOB emulsion incubated islets (0.02 ± 0.19 μg VEGF/mg total protein, n = 4, p < 0.05) at day 1. At day 3, VEGF secretion was increased as compared to day 1 in control (0.23 ± 0.04 μg VEGF/mg total protein) but it was imbalance by the presence of PFOB emulsion (0.09 ± 0.03 μg VEGF/mg total protein, n = 5, p < 0.05). While insulin secretion was maintained in response to a glucose stimulation test until day 3 when islets were incubated in the presence of PFOB emulsion preoxygenated (0.81 ± 0.16 at day 1 vs. 0.75 ± 0.24 at day 3), the ability to secrete insulin in the presence of high glucose concentration was lost in islets controls (0.51 ± 0.18 at day 1 vs. 0.21 ± 0.13 at day 3). Atmospheric oxygen delivery by PFOB emulsion might be sufficient to decrease islets hypoxia. However, to improve islets functionality, overoxygenation is needed. Finally, maintenance of islet viability and functionality for several days after isolation could improve the outcome of islets transplantation.

Abstract
BACKGROUND There is no consensus about the most effective method for transarterial chemoembolisation of hepatocellular carcinoma. AIM The aim of this phase II trial was to compare the efficacy and toxicity of lipiodol transarterial chemoembolisation with amiodarone in association with pirarubicin or doxorubicin versus lipiodol transarterial chemoembolisation with anthracycline alone in a control group. METHODS Patients with unresectable hepatocellular carcinoma and Child-Pugh A/B7 were considered eligible for the trial. transarterial chemoembolisation was repeated every 6 weeks for a maximum of 4 sessions. RESULTS Thirteen patients were randomised in the amiodarone group, and 14 were randomised in the control group. The two groups were comparable with respect to their baseline characteristics. The objective response rate according to the EASL criteria was 62% (95% CI 35-88) in the amiodarone group and 50% (95% CI 24-76) in the control group. At 1 and 2 years, survival rates were 77% (95% CI 44-92) and 52% (95% CI 22-75) in the amiodarone group, and 57% (95% CI 28-78) and 40% (95% CI 15-65) in the control group, respectively. There was no difference between the two groups in terms of toxicity. CONCLUSIONS The results of this study suggest that lipiodol transarterial chemoembolisation with anthracycline and amiodarone was safe but did not increase survival compared with lipiodol transarterial chemoembolisation with anthracycline alone in patients with hepatocellular carcinoma.

Abstract
Delayed and insufficient revascularization during islet transplantation deprives islets of oxygen and nutrients, resulting in graft failure. Vascular endothelial growth factor (VEGF) could play a critical role in islet revascularization. We aimed to develop pharmacological strategies for VEGF overexpression in pancreatic islets using the iron chelator deferoxamine (DFO), thus avoiding obstacles or safety risks associated with gene therapy. Rat pancreatic islets were infected in vivo using an adenovirus (ADE) encoding human VEGF gene (4.108 pfu/pancreas) or were incubated in the presence of DFO (10 μmol/L). In vitro viability, functionality, and the secretion of VEGF were evaluated in islets 1 and 3 days after treatment. Infected islets or islets incubated with DFO were transplanted into the liver of syngenic diabetic rats and the graft efficiency was estimated in vivo by measuring body weight, glycemia, C-peptide secretion, and animal survival over a period of 2 months. DFO induced transient VEGF overexpression over 3 days, whereas infection with ADE resulted in prolonged VEGF overexpression lasting 14 days; however, this was toxic and decreased islet viability and functionality. The in vivo study showed a decrease in rat deaths after the transplantation of islets treated with DFO or ADE compared with the sham and control group. ADE treatment improved body weight and C-peptide levels. Gene therapy and DFO improved metabolic control in diabetic rats after transplantation, but this effect was limited in the presence of DFO. The pharmacological approach is an interesting strategy for improving graft efficiency during transplantation, but this approach needs to be improved with drugs that are more specific.

Abstract
PURPOSE Controversy exists regarding whether or not amifostine might reduce the efficacy of cancer treatment. The aim of this meta-analysis was to evaluate the impact of amifostine on overall survival (OS) and progression-free survival (PFS) in patients treated with radiotherapy or chemoradiotherapy. MATERIAL AND METHODS Updated data from individual patients with non-small-cell lung cancer, head and neck squamous cell carcinoma, and pelvic cancer treated with radiotherapy or chemoradiotherapy and randomly assigned to amifostine or not were included. The primary end point was OS. RESULTS Twenty-two randomized trials (2279 patients) were potentially eligible. Data were available for 16 trials (1554 patients), but four trials (435 patients) were excluded after data checking. Ultimately 12 trials and 1119 patients were analyzed. A total of 431 patients were treated with radiotherapy alone (three trials), and 688 patients were treated with chemoradiotherapy (nine trials). Thirty-three percent of patients had lung cancers, 65% had head and neck cancers, and 2% had pelvic carcinomas. Ninety-one percent of patients had locally advanced disease (early stage, 9%). Median follow-up was 5.2 years. The hazard ratio (HR) of death was 0.98 (95% CI, 0.84 to 1.14; P = .78). On the basis of 11 trials (1091 patients), the HR of progression, relapse, or death was 1.05 (95% CI, 0.90 to 1.22; P = .53). The tests for heterogeneity were not significant (P ≥ .73), and there was no significant variation of treatment effect according to sex, age, tumor site, stage, histology, locoregional treatment, or type of administration for either end point. CONCLUSION Amifostine did not reduce OS and PFS in patients treated with radiotherapy or chemoradiotherapy.

Abstract
Hepatocellular carcinoma (HCC) is the main type of primary liver cancers and the third most common cause of cancer mortality worldwide. In France, rising number between 5000 and 6000 cases are diagnosed each year. The major risk factor for hepatocellular carcinoma is chronic hepatitis: viral hepatitis B, viral hepatitis C, consumption of alcohol, hemochromatosis. Hepatocellular carcinoma is closely associated to liver cirrhosis, which is a true precancerous state. Because hepatocarcinogenesis is a long and heterogeneous process, there is still much to understand. Many genetic and epigenetic alterations are described leading to changes in cellular signalling cascades involved in regulation of growth, differentiation, apoptosis, motility. Hepatitis viruses play a direct oncogenic role through the interaction between viral and cellular proteins, which control cell homeostasis, or by the integration of hepatitis B virus genome into the host genome. Furthermore, hepatitis viruses play an indirect oncogenic role by causing chronic inflammation and hepatocyte regeneration related to viral hepatopathy. In expectation of a better understanding of hepatocarcinogenesis and new treatments, prevention from risk factors and ultrasonographic screening of patients with cirrhosis should increase prognosis.

Abstract
BACKGROUND Several trials have studied the role of altered fractionation radiotherapy in head and neck squamous cell carcinoma, but the effect of such treatment on survival is not clear. OBJECTIVES The aim of this individual patient data (IPD) meta-analysis was to assess whether this type of radiotherapy could improve survival. SEARCH STRATEGY We searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; CENTRAL (2010, Issue 3); PubMed; EMBASE; CINAHL; Web of Science; BIOSIS Previews; Cambridge Scientific Abstracts; ISRCTN and additional sources for published and unpublished trials. The date of the most recent search was 8 August 2010. SELECTION CRITERIA We identified randomised trials comparing conventional radiotherapy with hyperfractionated or accelerated radiotherapy, or both, in patients with non-metastatic head and neck squamous cell carcinomas and grouped trials into three pre-specified treatment categories: hyperfractionated, accelerated and accelerated with total dose reduction. Trials were eligible if they began recruitment after 1969 and ended before 1998. DATA COLLECTION AND ANALYSIS We obtained updated individual patient data. Overall survival was the main outcome measure. The secondary outcome measures were local or regional control rates (or both), distant control rates and cause-specific mortality. MAIN RESULTS We included 15 trials with 6515 patients. The median follow up was six years. Tumour sites were mostly oropharynx and larynx; 5221 (74%) patients had stage III-IV disease (UICC 2002). There was a significant survival benefit with altered fractionation radiotherapy, corresponding to an absolute benefit of 3.4% at five years (hazard ratio (HR) 0.92, 95% CI 0.86 to 0.97; P = 0.003). The benefit was significantly higher with hyperfractionated radiotherapy (8% at five years) than with accelerated radiotherapy (2% with accelerated fractionation without total dose reduction and 1.7% with total dose reduction at five years, P = 0.02). There was a benefit in locoregional control in favour of altered fractionation versus conventional radiotherapy (6.4% at five years; P < 0.0001), which was particularly efficient in reducing local failure, whereas the benefit on nodal control was less pronounced. The benefit was significantly higher in the youngest patients (under 50 year old) (HR 0.78, 95% CI 0.65 to 0.94), 0.95 (95% CI 0.83 to 1.09) for 51 to 60 year olds, 0.92 (95% CI 0.81 to 1.06) for 61 to 70 year olds, and 1.08 (95% CI 0.89 to 1.30) for those over 70 years old; test for trends P = 0.007). AUTHORS' CONCLUSIONS Altered fractionation radiotherapy improves survival in patients with head and neck squamous cell carcinoma. Comparison of the different types of altered radiotherapy suggests that hyperfractionation provides the greatest benefit. An update of this IPD meta-analysis (MARCH 2), which will increase the power of this analysis and allow for other comparisons, is currently in progress.

Abstract
BACKGROUND The Fédération Francophone de Cancérologie Digestive phase III trial in patients with metastatic pancreatic adenocarcinoma comparing 5FU, folinic acid and cisplatin combination followed by gemcitabine (Arm A) versus the opposite sequence (Arm B) failed to demonstrate a benefit in overall survival. To longitudinally compare the quality of life (QoL) we explored different definitions of time until definitive deterioration (TUDD) of QoL scores according to minimal clinically important difference (MCID) cut-offs. METHODS QoL was evaluated using the EORTC QLQ-C30 every 8 weeks until death. The following scores were analysed: global health, emotional functioning, physical functioning, fatigue and pain. TUDD was defined as the time interval between randomisation and the first occurrence of a decrease in QLQ-C30 score ≥5 points without any further improvement in QoL score ≥5 points or any further available QoL data. Analyses were repeated using a 10 point MCID and/or including death as event. RESULTS From 08/2003 to 05/2006, 102 patients in Arm A and 100 in Arm B were included. Using a 5 and a 10 point MCID, TUDD curves of the 5 scores did not differ according to treatment arm., The median TUDD of global health was 5.2 months (4.3-6.2) in Arm A and 6.1 months (5.1-8.5) in Arm B (log-rank p=0.50) including death as an event for a 5 point MCID. Multivariate Cox model showed that tumour localisation and progression were independently associated with TUDD (p<0.05). CONCLUSIONS The strategy of chemotherapy did not influence the deterioration of QoL. The TUDD approach seems to provide meaningful clinical results that are adapted to metastatic pancreatic adenocarcinoma trials.

Abstract
Abstract
The aim of the study was to investigate the residual blood level of O before each cycle of various oxaliplatin (O) based protocols, and to explore its predictive value for potential occurrence of a severe neurotoxicity.
Methods: Between 11/2005 and 06/2008, 220 Pts were included in a prospective cohort, in 7 French centers. Patients received a minimum of 7 cycles of O.
Blood samples were taken before each cycle with a maximum of 12 cycles. In parallel neurotoxicity was assessed by the modified Levi score (grade 0 to 3) and by the Von Frey filament exam. Saliva was collected before the first cycle for genomics analysis. The O concentration was obtained by Atomic Absorption Spectrometry assay after nitric digestion of total blood. Polymorphism of different targets were investigated (carrier proteins: MRP2, OCT1, OCT2, GSTP1, adducts repair system: ERCC1, ERCC2). Time to first severe neurotoxicity occurrence (TTSN Events: Grade 2 or3) was estimated using Kaplan-Meier. Predictive value of severe neurotoxicity was explored using univariate and multivariate logistic or Cox regressions. Harrel C index was produced.
Results: 206 pts with gastro-intestinal cancer had, at the time of analysis, completed follow-up and 201 pts (91.3%) were eligible for pharmacokinetics. (85%) received FOLFOX regimen (85mg/m2every 2 weeks), the others GEMOX or XELOX (100mg/m2 every 3 weeks). The mean total dose of O received for all pts was 1.18 ± 0.4 g.
After cycle 1, 2 and 10, median residual level of O was respectively 0.31 mg/L, 0.43 mg/L and 0.60 mg/L. The maximal concentration was obtained between cycle 5 and cycle 9. Respectively 89 Pts (44%) and 15 pts (7%) had a Gr2 and a Gr3 neurotoxicity. Median time TTSN was 141 days (95% CI: 132 – 161). O concentration before 2nd cure (HR = 1.39, p < 0.0001) is associated with TTSN (cure N°2 for Gr0 and Gr1, cure N° 7 for Gr2 and Gr3) but not with the frequency. Multivariate logistic and Cox analyses confirmed these results.
Conclusions: 1. The mean residual blood level of O before the second cure is correlated with the occurrence of Gr2 or Gr3 neurotoxicity (p Mann-Whitney = 0.0007)
2. The residual blood level of O before the second O cure is correlated with the delay of occurrence of a Gr2 or Gr3 neurotoxicity in patients receiving an O based-regimen (Harrel C=0.54, p=0.021). Further statistical analyses will be done to analyse the data from the Von Frey filaments and the gene polymorphism and will be presented at the meeting. An O posology adaptation or infusion duration modification based on Platinum residual level of cure 1 have to be considered in future clinical trial in order to avoid severe Gr2 or Gr3 neurotoxicity.

Abstract
e17544 Background: The FFCD phase III trial in pts with MPA comparing LV5FU2-P followed by gemcitabine (arm A) versus the opposite sequence (arm B) had failed to demonstrate a significant difference in median OS. To longitudinally compare QoL according to treatment sequence we have explore definitions of time until definitive deterioration (TUDD) of QoL scores according to minimal clinically important difference (MCID) cut off. Methods: From August 2003 to May 2006, 202 pts with measurable MPA, PS 0–2, non prior CT were included in 33 centers, 102 in arm A and 100 in arm B. QoL was evaluated using EORTC QLQ-C30 every 8 wks up to death. We focused analyses on the following scores: global health (GH), emotional functioning (EF), physical functioning (PF), fatigue (FA), and pain (PA). TUDD were estimated using Kaplan Meier, and compared using log-rank tests. They were defined as the time interval between randomization and the first occurrence of a decrease in QLQ-C30 score ≥ 5 points without any further improvement in QoL score ≥ 5 points or any further available QoL data. These analyses were repeated using a 10 points MCID, and by including deaths as event. Results: Amongst the 202 pts, 179 had completed at least one QoL questionnaire (89%) and the mean number of available QoL data was 3 (SD: 2.14). Using a 5 points MCID as well as 10 points, TUDD of the 5 scores did not differ according to treatment arm. About 25% of patients reported definitive score deteriorations≥ 5 points and 15%≥ 10 points. Including death as event for a 5 points MCID, median TUDD of GH score was 5.2 months (4.3–6.2) in Arm A and 6.1 months (5.1–6.1) in Arm B (log rank p = 0.50). Median TUDD of FA score was 4.8 months (3.5–6.3) in Arm A and 5.6 months (4.2–7.7) in Arm B (log rank p = 0.76). Median TUDD of scores was reached after median PFS and at median time of second-line PFS. While treatment had no impact, multivariate Cox model showed that tumor localization and progression were independently associated with TTDU (p < 0.05). Conclusions: We have investigated QoL analyses modalities using survival techniques dealing with binding drop out missing data and with an easier clinical interpretation of results. Progression seems to negatively impact QoL. No significant financial relationships to disclose.

Abstract
BACKGROUND Our previous individual patient data (IPD) meta-analysis showed that chemotherapy improved survival in patients curatively treated for non-metastatic head and neck squamous cell carcinoma (HNSCC), with a higher benefit with concomitant chemotherapy. However the heterogeneity of the results limited the conclusions and prompted us to confirm the results on a more complete database by adding the randomised trials conducted between 1994 and 2000. METHODS The updated IPD meta-analysis included trials comparing loco-regional treatment to loco-regional treatment+chemotherapy in HNSCC patients and conducted between 1965 and 2000. The log-rank-test, stratified by trial, was used to compare treatments. The hazard ratios of death were calculated. RESULTS Twenty-four new trials, most of them of concomitant chemotherapy, were included with a total of 87 trials and 16,485 patients. The hazard ratio of death was 0.88 (p<0.0001) with an absolute benefit for chemotherapy of 4.5% at 5 years, and a significant interaction (p<0.0001) between chemotherapy timing (adjuvant, induction or concomitant) and treatment. Both direct (6 trials) and indirect comparisons showed a more pronounced benefit of the concomitant chemotherapy as compared to induction chemotherapy. For the 50 concomitant trials, the hazard ratio was 0.81 (p<0.0001) and the absolute benefit 6.5% at 5 years. There was a decreasing effect of chemotherapy with age (p=0.003, test for trend). CONCLUSION The benefit of concomitant chemotherapy was confirmed and was greater than the benefit of induction chemotherapy.

Abstract
During pancreatic islet transplantation, delayed and insufficient revascularization can deprive islets of oxygen and nutrients, resulting in cell death and early graft failure. Deferoxamine (DFO), an iron chelator, increases vascular endothelial growth factor (VEGF) expression in cells. The aim of this work was to study the effect of DFO on beta-cell and pancreatic islet viability as well as VEGF expression. beta-cell lines from rat insulinoma (Rin m5f) and primary cultures of pancreatic islets from Wistar rats were incubated with DFO (10, 100, and 1000 micromol/L). The viability was evaluated using fluorescein diacetate/propidium iodide for dying pancreatic islets and using cell titers for Rin m5f. Expression of VEGF messenger RNA (mRNA) was quantified using reverse transcriptase polymerase chain reaction (RT-PCR). Finally, VEGF secretion was determined using enzyme-linked immunosorbent assays at 1 to 3 days after treatment. The addition of 10 micromol/L of DFO preserved Rin m5F viability at 24 hours after treatment (10 micromol/L; 101.33% +/- 5.66%; n = 7). However, 100 and 1000 micromol/L of DFO induced cell death (68.92% +/- 5.83% and 65.89% +/- 5.83%, respectively; n = 4). In the same way, viability of pancreatic islets in the presence of DFO was preserved. RT-PCR analysis showed stimulation of VEGF mRNA in the presence of 10 micromol/L of DFO in islets at 3 days after culture. Finally, 10 micromol/L of DFO stimulated secretion of VEGF 7.95 +/- 0.84 versus 1.80 +/- 1.10 pg/microg total protein with 10 micromol/L of DFO in rat islets at 3 days after culture, n = 3; P < .001). The use of DFO to stimulate VEGF expression and increase islet vascularization may be a realistic approach to improve islet viability during transplantation.

Abstract
A familial translocation t(X;21)(q2700;q11) is studied. A girl, trisomic for almost all the chromosome 21, has a mildly abnormal phenotype. A second girl, phenotypically abnormal, is monosomic for the juxtacentromeric region of chromosome 21 only. A comparison of the replication pattern and of the activity of superoxide dismutase (gene located on chromosome 21) shows a clear correlation between late replication, gene inactivation and phenotype expression of chromsome 21.
