Abstract

Summary Background Although clinical trials have demonstrated that adjuvant chemotherapy improves survival for stage-III colon cancer, the benefits remain controversial for stage-II lesions. The objective of the present study was to determine the extent to which adjuvant chemotherapy is used for patients with stage-II and -III colon cancers. Methods The study population comprised 1074 patients with stage-II and -III colon cancers diagnosed in 2000 in 12 French administrative districts and recorded in population-based cancer registries. Data were collected using a standardized procedure. Results Overall, 20.4% of patients with stage II and 61.9% with stage III received adjuvant chemotherapy. Age at diagnosis was the strongest determinant of chemotherapy. Among stage-II patients, those receiving chemotherapy decreased from 57.6% in patients aged ≤ 50 years to 1.1% in those aged ≥ 85. The corresponding percentages with stage III were 93.6% and 1.4%. In multivariate analyses, other factors found to be independently and significantly associated with administration of adjuvant chemotherapy for stage II were extension of the cancer (stage IIA vs. stage IIB), clinical presentation (obstruction or perforation vs. uncomplicated cancer) and discussion of the case at a multidisciplinary case-review meeting. For stage III, apart from age, discussion of the case at a multidisciplinary meeting was the only factor independently associated with administration of chemotherapy. Conclusion Adjuvant chemotherapy for stage-III colon cancer is used extensively for patients under 75 years of age. However, many elderly patients do not receive such treatment. On the other hand, a substantial percentage of stage-II colon cancer patients receive adjuvant chemotherapy despite its uncertain benefits.

Abstract

International audience; Using a multilevel Cox model, the association between socioeconomic and geographical aggregate variables and survival was investigated in 81 268 patients with digestive tract cancer diagnosed in the years 1980-1997 and registered in 12 registries in the French Network of Cancer Registries. This association differed according to cancer site: it was clear for colon (relative risk (RR)=1.10 (1.04-1.16), 1.10 (1.04-1.16) and 1.14 (1.05-1.23), respectively, for distances to nearest reference cancer care centre between 10 and 30, 30 and 50 and more than 90 km, in comparison with distance of less than 10 km; P-trend=0.003) and rectal cancer (RR=1.09 (1.03-1.15), RR=1.08 (1.02-1.14) and RR=1.12 (1.05-1.19), respectively, for distances between 10 and 30 km, 30 and 50 km and 50 and 70 km, P-trend=0.024) (n=28 010 and n=18 080, respectively) but was not significant for gall bladder and biliary tract cancer (n=2893) or small intestine cancer (n=1038). Even though the influence of socioeconomic status on prognosis is modest compared to clinical prognostic factors such as histology or stage at diagnosis, socioeconomic deprivation and distance to nearest cancer centre need to be considered as potential survival predictors in digestive tract cancer.

Abstract

International audience; INTRODUCTION: Lung cancer is the most common cause of death from malignant disease in the world. Our objective was to describe the progression of this cancer's incidence, and the changing distribution of histological types in France between 1978 and 2000. METHODS: National incidence rates were obtained by modelling lung cancer incidence data provided by the French cancer registries, taking into account national mortality data. These registries also provided information about histological type. RESULTS: In the year 2000, with 28,000 estimated new diagnoses, lung cancer represented 10.0% of all incident cancers and was responsible for 18.1% of deaths from cancer. From 1980 to 2000, the incidence rose from 47.4 to 52.2 per hundred thousand in men and from 3.7 to 8.6 per hundred thousand in women. The risk of developing lung cancer, which remained constant in men, has increased considerably (+451%) between the generation of women born in 1953 and those born in 1913. The proportion of epidermoid cancers has dropped whilst that of adenocarcinomas has risen sharply. CONCLUSIONS: The last few years have seen a large increase in the incidence of lung cancer in women and an increasing incidence of adenocarcinoma in both men and women.

Abstract

International audience; Fifty-five inclusive single nucleon-removal cross sections from medium mass neutron-rich nuclei impinging on a hydrogen target at $\sim$250 MeV=nucleon are measured at the RIKEN Radioactive Isotope Beam Factory. Systematically higher cross sections are found for proton removal from nuclei with an even number of protons as compared to odd-proton number projectiles for a given neutron separation energy. Neutron removal cross sections display no even-odd splitting, contrary to nuclear cascade model predictions. Both effects are understood through simple considerations of neutron separation energies and bound state level densities originating in pairing correlations in the daughter nuclei. These conclusions are supported by comparison with semimicroscopic model predictions, highlighting the enhanced role of lowlying level densities in nucleon-removal cross sections from loosely bound nuclei

Abstract

Background Merkel cell carcinoma (MCC) is a rare primary cutaneous neuroendocrine carcinoma. Owing to its low incidence, epidemiological data are scarce and have never been analysed in France to identify the main epidemiological trends. Methods Data from MCC patients diagnosed between 1998 and 2010 were obtained from 11 French cancer registries in the FRANCIM network. The main epidemiological characteristics of MCC were investigated between 2006 and 2010 because comprehensive data were only available for this period. The main focus was tumour incidence and mortality over time. Results Between 1998 and 2010, 562 cases of MCC were reported in the registries. From 2006 to 2010 (290 cases), European- and world-standardized incidence rates were 0.26 and 0.43 per 100,000 person-years in men and 0.24 and 0.38 per 100,000 person-years in women. MCC is more frequent in females in France (56.9%) with male/female ratio 1.1. Relative survival rates were 84%, 56% and 42% at one, three and 5 years, respectively. Conclusions The incidence of MCC clearly increased over time in all areas under focus. The standardized incidence in France was comparable to the incidence observed in other countries for the same period, but French data are too recent to conclude on an increase in MCC incidence. Prognosis remains poor in all countries in which data are available.

Abstract

We report on the measurement of the rst 2+ and 4+ states of 66Cr and 70;72Fe via in-beam -ray spectroscopy. The nuclei of interest were produced by (p; 2p) reactions at incident energies of 260 MeV/nucleon. The experiment was performed at the Radioactive Isotope Beam Factory, RIKEN using the DALI2 -ray detector array and the novel MINOS device, a thick liquid hydrogen target combined with a vertex tracker. A low-energy plateau of 2+ 1 and 4+ 1 energies as a function of neutron number was observed for N38 and N40 for even-even Cr and Fe isotopes, respectively. State-of-the-art shell model calculations with a modied LNPS interaction in the pfg9=2d5=2 valence space reproduce the observations. Interpretation within the shell model shows an extension of the Island of Inversion at N=40 towards neutron-rich isotopes and hints at a smooth transition to collective N=50 Cr and Fe isotopes.

Abstract

The main characteristics of the COMPASS experimental setup for physics with hadron beams are described. This setup was designed to perform exclusive measurements of processes with several charged and/or neutral particles in the final state. Making use of a large part of the apparatus that was previously built for spin structure studies with a muon beam, it also features a new target system as well as new or upgraded detectors. The hadron setup is able to operate at the high incident hadron flux available at CERN. It is characterised by large angular and momentum coverages, large and nearly flat acceptances, and good two and three-particle mass resolutions. In 2008 and 2009 it was successfully used with positive and negative hadron beams and with liquid hydrogen and solid nuclear targets. This article describes the new and upgraded detectors and auxiliary equipment, outlines the reconstruction procedures used, and summarises the general performance of the setup., Comment: 91 pages, 101 figures and 7 tables

Abstract

For the first time in the history of high energy astronomy, a large CdTe gamma-ray camera is operating in space. ISGRI is the low-energy camera of the IBIS telescope on board the INTEGRAL satellite. This paper details its design and its in-flight behavior and performances. Having a sensitive area of 2621 cm$^2$ with a spatial resolution of 4.6 mm, a low threshold around 12 keV and an energy resolution of $\sim$ 8% at 60 keV, ISGRI shows absolutely no signs of degradation after 9 months in orbit. All aspects of its in-flight behavior and scientific performance are fully nominal, and in particular the observed background level confirms the expected sensitivity of 1 milliCrab for a 10$^6$s observation., Comment: INTEGRAL A&A special issue

Abstract

International audience; The Double Chooz experiment presents improved measurements of the neutrino mixing angle θ13 using the data collected in 467.90 live days from a detector positioned at an average distance of 1050 m from two reactor cores at the Chooz nuclear power plant. Several novel techniques have been developed to achieve significant reductions of the backgrounds and systematic uncertainties with respect to previous publications, whereas the efficiency of the ν¯¯¯e signal has increased. The value of θ13 is measured to be sin2 2θ13 = 0.090+ 0.032− 0.029 from a fit to the observed energy spectrum. Deviations from the reactor ν¯¯¯e prediction observed above a prompt signal energy of 4 MeV and possible explanations are also reported. A consistent value of θ13 is obtained from a fit to the observed rate as a function of the reactor power independently of the spectrum shape and background estimation, demonstrating the robustness of the θ13 measurement despite the observed distortion.

Abstract

We describe a muon track reconstruction algorithm for the reactor anti-neutrino experiment Double Chooz. The Double Chooz detector consists of two optically isolated volumes of liquid scintillator viewed by PMTs, and an Outer Veto above these made of crossed scintillator strips. Muons are reconstructed by their Outer Veto hit positions along with timing information from the other two detector volumes. All muons are fit under the hypothesis that they are through-going and ultrarelativistic. If the energy depositions suggest that the muon may have stopped, the reconstruction fits also for this hypothesis and chooses between the two via the relative goodness-of-fit. In the ideal case of a through-going muon intersecting the center of the detector, the resolution is ∼40 mm in each transverse dimension. High quality muon reconstruction is an important tool for reducing the impact of the cosmogenic isotope background in Double Chooz., National Science Foundation (U.S.), United States.

Abstract

The Double Chooz experiment measures the neutrino mixing angle θ13 by detecting reactor ν¯e via inverse beta decay. The positron-neutron space and time coincidence allows for a sizable background rejection, nonetheless liquid scintillator detectors would profit from a positron/electron discrimination, if feasible in large detector, to suppress the remaining background. Standard particle identification, based on particle dependent time profile of photon emission in liquid scintillator, can not be used given the identical mass of the two particles. However, the positron annihilation is sometimes delayed by the ortho-positronium (o-Ps) metastable state formation, which induces a pulse shape distortion that could be used for positron identification. In this paper we report on the first observation of positronium formation in a large liquid scintillator detector based on pulse shape analysis of single events. The o-Ps formation fraction and its lifetime were measured, finding the values of 44% ± 12% (sys.) ± 5% (stat.) and 3.68ns ± 0.17ns (sys.) ± 0.15ns (stat.) respectively, in agreement with the results obtained with a dedicated positron annihilation lifetime spectroscopy setup., National Science Foundation (U.S.), United States.

Abstract

International audience; FRESCA2 is a dipole magnet dedicated to upgrade the present CERN cable test station FRESCA to a nominal bore field of 13 Tesla (T) in a 100 mm clear aperture. This paper reports on the assembly process and the three cool-down tests to cryogenic temperature of the support structure of FRESCA2. This structure is based on an aluminum alloy shrinking cylinder pre-loaded through the use of water-pressurized bladders. To verify the assembly and loading processes, this structure was assembled using full block aluminum alloy ldquodummy coilsrdquo standing for the Nb 3Sn coils. Then, the whole assembled structure was cooled-down to 77 K with liquid nitrogen in a dedicated facility at CERN. The mechanical behavior was monitored at all stages by strain gauges located on different components of the structure. Three cryogenic tests were made by increasing the loading gradually up to values corresponding to the ultimate field of 15 T. The expected stresses within the structure after assembly, loading and cool-down were determined from the 3-D finite-element model of the support structure. A comparison of the model predictions with the strain gauge data is presented.

Abstract

We have performed tests of Micromegas detector prototypes using the heavy-ion beams from the SIS synchrotron of GSI (Darmstadt, Germany). The beams varied from C 6 + 12 to Au 65 + 179 and from 250 to 1000 MeV per nucleon. We have tested two amplification technologies, conventional and resistive Micromegas, and two construction concepts, bulk-Micromegas and micro-meshes screwed on the PCB. The obtained position resolution below 200 μ m for 5 mm wide strips implies that the bulk resistive Micromegas technology might meet the requirements of the future R3B TPC project. We also developed a fast and very low noise front-end electronics connected directly to the Printed Circuit Board (PCB) of the detector itself. This concept has shown very good performances and robustness.

Abstract

A Fabry-Perot cavity polarimeter, installed in 2003 at HERA for the second phase of its operation, is described. The cavity polarimeter was designed to measure the longitudinal polarisation of the HERA electron beam with high precision for each electron bunch spaced with a time interval of 96ns. Within the cavity the laser intensity was routinely enhanced up to a few kW from its original value of 0.7W in a stable and controllable way. By interacting such a high intensity laser beam with the HERA electron beam it is possible to measure its polarisation with a relative statistical precision of 2% per bunch per minute. Detailed systematic studies have also been performed resulting in a systematic uncertainty of 1%., 28 pages, 16 figures
