    BACKGROUND: Often curative treatment for locally advanced resectable esophageal or gastro-esophageal junctional cancer consists of concurrent neoadjuvant radiotherapy and chemotherapy followed by surgery. Currently, one of the most commonly used chemotherapy regimens in this setting is a combination of a fluoropyrimidin and of a platinum analogue. Due to the promising results of the recent CROSS trial, another regimen combining paclitaxel and carboplatin is also widely used by European and American centers. No clinical study has shown the superiority of one treatment over the other. The objective of this Phase II study is to clarify clinical practice by comparing these two chemotherapy treatments. Our aim is to evaluate, in operable esophageal and gastro-esophageal junctional cancer, the complete resection rate and severe postoperative morbidity rate associated with these two neoadjuvant chemotherapeutic regimens (carboplatin-paclitaxel or fluorouracil-oxaliplatin-folinic acid) when each is combined with the radiation regime utilized in the CROSS trial. METHODS/DESIGN: PROTECT is a prospective, randomized, multicenter, open arms, phase II trial. Eligible patients will have a histologically confirmed adenocarcinoma or squamous cell carcinoma and be treated with neoadjuvant radiochemotherapy followed by surgery for stage IIB or stage III resectable esophageal cancer. A total of 106 patients will be randomized to receive either 3 cycles of FOLFOX combined to concurrent radiotherapy (41.4 Grays) or carboplatin and paclitaxel with the same radiation regimen, using a 1:1 allocation ratio. DISCUSSION: This ongoing trial offers the unique opportunity to compare two standards of chemotherapy delivered with a common regimen of preoperative radiation, in the setting of operable locally advanced esophageal or gastro-esophageal junctional tumors.

    Les dommages aux arbres d’alignement dans Paris

    Les dĂ©gĂąts de la tempĂȘte sont innombrables : plus de 6 000 arbres abattus, plus de 80 lieux de culte et 520 Ă©tablissements scolaires endommagĂ©s, sans compter les dommages sur les bĂątiments et monuments remarquables. L’agglomĂ©ration parisienne n’est certes pas la Lorraine, oĂč les pertes s’élĂšvent Ă  18 millions de m3 de bois. Mais, sur l’ensemble des plantations de Paris, hormis les bois de Vincennes et de Boulogne, 5 540 arbres ont Ă©tĂ© accidentĂ©s dans les espaces verts (2 231), les cimetiĂšres ..

    Estimation of common cause failure parameters with periodic tests

    No full text
    International audienceIn the specific case of safety systems, CCF parameters estimators for standby components depend on the periodic test schemes. Classically, the testing schemes are either staggered (alternation of tests on redundant components) or non-staggered (all components are tested at the same time). In reality, periodic tests schemes performed on safety components are more complex and combine staggered tests, when the plant is in operation, to non-staggered tests during maintenance and refueling outage periods of the installation. Moreover, the CCF parameters estimators described in the US literature are derived in a consistent way with US Technical Specifications constraints that do not apply on the French Nuclear Power Plants for staggered tests on standby components. Given these issues, the evaluation of CCF parameters from the operating feedback data available within EDF implies the development of methodologies that integrate the testing schemes specificities. This paper aims to formally propose a solution for the estimation of CCF parameters given two distinct difficulties respectively related to a mixed testing scheme and to the consistency with EDF’s specific practices inducing systematic non-simultaneity of the observed failures in a staggered testing scheme

    Les nouveaux anticoagulants oraux (NACO) (Dabigatran, rivaroxaban) (ressenti des médecins généralistes picards sur leurs utilisations et leurs perspectives)

    Introduction : L anti-coagulation actuelle est dominĂ©e par les AVK et les hĂ©pariniques ; de nouvelles molĂ©cules plus simples et au moins aussi efficaces sont arrivĂ©es dans la pharmacopĂ©e : les NACO(nouveaux anticoagulants oraux : dabigatran et rivaroxaban) ; cependant leurs utilisations restent parcimonieuses. MatĂ©riels et mĂ©thodes : Nous avons menĂ© une Ă©tude observationnelle sur le ressenti des mĂ©decins gĂ©nĂ©ralistes(M-G) picards vis-Ă -vis de ces NACO, par le biais d un questionnaire en ligne envoyĂ© Ă  un Ă©chantillon reprĂ©sentatif de 600 M-G picards. RĂ©sultats : Nous avons mis en Ă©vidence que les NACO prĂ©sentaient divers intĂ©rĂȘts dans leurs conforts d utilisation (corrigeant ainsi le dĂ©faut principal des AVK), grĂące Ă  un dosage fixe et une absence de surveillance. Cependant les freins Ă  leurs prescriptions Ă©taient nombreux, notamment l absence d antidote et le manque de recul vis-Ă -vis de ces molĂ©cules (qui ont pu se montrer dangereuses). Discussion : Pour l HAS, les NACO ne prĂ©sentaient pas d amĂ©lioration du service mĂ©dical rendu et leur prix Ă©tait bien plus important que celui des AVK. Dans un contexte de rĂ©duction des dĂ©penses de santĂ©, le confort d utilisation justifie t il une prise de risque pour le patient et un coĂ»t majorĂ©. Conclusion : Pour conclure les M-G picards estimaient que les NACO devaient ĂȘtre utilisĂ©s uniquement dans les cas oĂč les traitements classiques, s avĂšrent inadaptĂ©s. Ils ne font pas rĂ©fĂ©rence actuellement dans l anti-coagulation ; mais une sĂ©curisation et un coĂ»t adaptĂ© pourraient changer la donne.AMIENS-BU SantĂ© (800212102) / SudocSudocFranceF
