Background: We investigated the impact of municipality of residence on colonoscopic surveillance and colorectal cancer risk after adenoma resection in a French well-defined administrative area.
Methods: This registry-based study included all patients residing in Côte d'Or (n=5769) first diagnosed with colorectal adenomas between January 1, 1990, and December 31, 1999. Information about colonoscopic surveillance and colorectal cancer incidence was collected until December 31, 2003.
Computed tomography (CT) is the core imaging modality for the evaluation of thoracic disorders. With the recently developed dual-energy CT (DECT) technique, the clinical utility of CT in the management of pulmonary diseases can be expanded. The most actively investigated principle of dual energy is material decomposition based on attenuation differences at different energy levels.

A negative slope of the rapidity-odd directed flow component with approximately 3 times smaller magnitude than found at the highest RHIC energy is observed.

Materials And Methods: A total of 121 smokers underwent a high-pitch and high-temporal resolution computed tomography (CT) angiographic examination, enabling quantification of emphysema, total lung volume, and LA volume measurements normalized to body surface area.
Results: The CT phenotypes were as follows: emphysema predominant (group 1; n=57); airway predominant (group 2; n=30); a mixed pattern of emphysema and airway disease (group 3; n=15); and absence of bronchopulmonary CT abnormalities (group 4; n=19).
Cardiac fibroblasts are an integral part of the myocardial tissue and contribute to its remodelling. This study characterises for the first time the calcium-dependent chloride channels (CaCC) in the plasma membrane of primary human atrial cardiac fibroblasts by means of the iodide efflux and the patch clamp methods. The calcium ionophore A23187 and Angiotensin II (Ang II) activate a chloride conductance in cardiac fibroblasts that shares pharmacological similarities with calcium-dependent chloride channels.

The bouffia Bonneval at La Chapelle-aux-Saints is well known for the discovery of the first secure Neandertal burial in the early 20th century. However, the intentionality of the burial remains an issue of some debate. Here, we present the results of a 12-y fieldwork project, along with a taphonomic analysis of the human remains, designed to assess the funerary context of the La Chapelle-aux-Saints Neandertal.

Purpose: The goal of this study was to evaluate the interest of the members of the French society of young radiation oncologists (SFjRO) for brachytherapy as well as their theoretical and practical level in this radiation technique.
Materials And Methods: An anonymous survey was conducted regarding practical and theoretical teaching of brachytherapy before the French national courses on brachytherapy.
Results: Among the 106 residents attending this teaching course, 99 (93%) answered the survey.
The ALICE measurement of K(S)(0) and Λ production at midrapidity in Pb-Pb collisions at √(s(NN))=2.76 TeV is presented. The transverse momentum (p(T)) spectra are shown for several collision centrality intervals and in the p(T) range from 0.

Large-scale excavations of Middle Palaeolithic open-air sites and refitting studies of the retrieved assemblages have yielded new, high-resolution data on the mobile aspects of Neandertal stone tool technology. In this paper, we integrate lithic technology and raw material data from recent studies of Middle Palaeolithic open-air and rock shelter sites in Western Europe.

NIS is also expressed, but poorly functional, in some non-thyroid human cancers. In particular, it is much more strongly expressed in cholangiocarcinoma (CCA) and hepatocellular carcinoma (HCC) cell lines than in primary human hepatocytes (PHH).

Recent findings have shown that the classical methods used for the estimation of net survival from cancer registry data, referred as to "relative-survival methods," provided biased estimates.
Objectives: The aim of this study was to provide, for the first time, long-term net survival rates for colorectal cancer by using a population-based digestive cancer registry.
Objectives: To assess the extent to which stage at diagnosis and adherence to treatment guidelines may explain the persistent differences in colorectal cancer survival between the USA and Europe.
Design: A high-resolution study using detailed clinical data on Dukes' stage, diagnostic procedures, treatment and follow-up, collected directly from medical records by trained abstractors under a single protocol, with standardised quality control and central statistical analysis.
Setting And Participants: 21 population-based registries in seven US states and nine European countries provided data for random samples comprising 12 523 adults (15-99 years) diagnosed with colorectal cancer during 1996-1998.
Background: The optimal immunochemical test to use for generalised mass screening is still under debate in France.
Aim: To compare the cost and effectiveness in biennial screening for colorectal cancer of fifteen strategies consisting of the three-stool sample un-rehydrated guaiac faecal occult blood test and three immunochemical tests: Magstream, FOB-Gold and OC-Sensor, at different positivity cut-off levels and stool-sample collection.
Methods: A Markov model was used to compare these strategies in a general population of 100,000 individuals aged 50-74 over a 20-year period.
Objectives: A national survey was conducted among the radiation oncology residents about their clinical activities and responsibilities. The aim was to evaluate the clinical workload and to assess how medical tasks are delegated and supervised.
Materials And Methods: A first questionnaire was administered to radiation oncology residents during a national course.
Soft tissue sarcoma is a rare entity and heterogeneous disease and its management therefore requires an experienced multidisciplinary team in an expert center. Standard treatment for grade 2 and 3 sarcomas is a conservative, extended surgery planned according to the results of the biopsy, and radiotherapy usually administered postoperatively (or pre-operatively). The indications for preoperative radiotherapy are discussed in a multidisciplinary meeting for locally advanced tumours.

The aim of this study was to evaluate the diffusion of adjuvant treatments in a French population.
Methods: 334 incident gastric cancers UICC Stage IB, II, III or IVM0 resected for cure and recorded in the Burgundy digestive cancer registry were retrospectively included.
Objective: To evaluate the clinical impact of automatic tube voltage selection on chest CT angiography (CTA).
Methods: Ninety-three patients were prospectively evaluated with a CT protocol aimed at comparing two successive CTAs acquired under similar technical conditions except for the kV selection: (1) the initial CTA was systematically obtained at 120 kVp and 90 ref mAs; (2) the follow-up CTA was obtained with an automatic selection of the kilovoltage (Care KV; Siemens Healthcare) for optimised CTA.
Results: At follow-up, 90 patients (97 %) underwent CTA with reduced tube voltage, 100 kV (n = 26; 28 %) and 80 kV (n = 64; 69 %), resulting in a significant dose-length-product reduction (follow-up: 87.
Aim Of The Study: To describe trends in survival of non-resectable metastatic colorectal cancer (MCRC) over a 34-year period in a French population-based registry taking into account major advances in medical therapy.
Patients And Methods: 3804 patients with non-resectable metastatic colorectal cancer diagnosed between 1976 and 2009 were included. Three periods (1976-96, 1997-2004 and 2005-09) were considered.
Aim: Little is known about patterns of recurrence in obstructing colon cancer (OCC) at a population level. The aim of this study was to determine the risk of recurrence following potentially curative surgery in OCC compared with that in uncomplicated colon cancer (CC).
Method: Data were obtained from the population-based digestive cancer registry of Burgundy (France).
