Full Text Available L’ouvrage récent de Guylaine Massoutre, Renaissances. Vivre avec Joyce, Aquin, Yourcenar présente, à la faveur d’une prose échevelée et lyrique, volontiers baroque, le parcours d’une biographe fictive, elle-même personnage d’une fiction d’Aquin, sur les traces des figures littéraires qui ont déclenché son envie d’écrire. L’étude entend montrer comment cet ouvrage joue avec finesse des ancrages générique, énonciatif, culturel et esthétique de l’exercice biographique. With the help of an unbridled and lyrical prose that is wilfully baroque, the recent work of Guylaine Massoutre, entitled Renaissances. Vivre avec Joyce, Aquin, Yourcenar, presents the course of a fictitious biographer, herself a character of an Aquinian fiction, as she follows the traces of the literary figures who inspired her desire to write. This study intends to show the way in which the work plays ingeniously upon the generic, enunciative, cultural and aesthetic foundations of the biographical endeavour.

L'application de cette methode de scintigraphie du cerveau a permis, en outre, de constater que la neohydrine marquee avec {sup 197}Hg etait localisee aussi bien dans les lymphomes que dans les carcinomes. Il semble y avoir depot selectif de la substance radioactive au niveau intercellulaire. Les zones de fixation accrue de la radioactivite peuvent etre aisement delimitees avec des agents scintigraphiques courants. Des essais sur 88 patients on montre que la neohydrine marquee avec {sup 197}Hg etait egalement utile comme agent de detection pour differencier les tumeurs des yeux; enfin, on a constate tout recemment qu'elle se concentrait dans les tumeurs rhino-pharyngiennes, que l'on pouvait alors delimiter par photoscintigraphie.

L'hyperoxalurie primitive est une anomalie métabolique congénitale rare caractérisée par un excès de production avec accumulation d'oxalate secondaire à un déficit enzymatique hépatique. Nous rapportons le cas d'un patient de 18 ans qui avait comme antécédent des lithiases rénales récidivantes depuis l'enfance évoluant vers l'insuffisance rénale chronique terminale, mis en hémodialyse périodique depuis 4 ans avec apparition d'une anémie résistante à l’érythropoïétine pour laquelle il a été multitransfusé et qui était admis pour prise en charge de douleurs osseuses invalidantes d'aggravation progressive associées à un syndrome tumoral fait d'adénopathies périphériques et de splénomégalie avec dyspnée et altération de l’état général. Le bilan réalisé avait objectivé de multiples images lytiques lacunaires et condensantes au niveau des poignets et des mains avec des petits reins calcifiés, une pleurésie avec péricardite de grande abondance drainée, une ascite de moyenne abondance avec splénomégalie homogène, une anémie normochrome normocytaire à 7.2 g/dl avec hyperferritinémie à 1129 μg/l et un syndrome inflammatoire biologique. La calcémie était spontanément normale à 97 mg/l avec hyperphosphorémie à 83 mg/l et hypoparathyroïdie à 74,85 pg/ml. Les PAL étaient à 136 UI/l, l'aluminium sérique à 13μg/l et la Vitamine D native à 20,87ng/ml. Le diagnostic d'hyperoxalurie a été retenu sur les données de la biopsie ostéomédullaire objectivant des dépôts de cristaux d'oxalate de calcium avec fibrose médullaire et réaction macrophagique à corps étranger. L’évolution a été marquée par la survenue de fractures spontanées récidivantes au niveau de l’épaule et des 2 hanches. PMID:25328593

Differentiated thyroid cancer (DTC) is generally associated with a good prognosis. Local recurrences, mainly lymph-node involvement, account for 15-20% of cases and are surgically treated. Distant metastases, mostly in lungs and more rarely in bones, are present in 5% of patients. When iodine uptake is sufficient (in approximately 60% of patients), distant metastases can be destroyed by iterative activities of iodine 131. Serum thyroglobulin (Tg), which can be assessed either on hormonal treatment or on TSH stimulation is considered as the tumour marker in DTC. Functional (iodine 131 scintigraphy, FDG PET, bone scintigraphy) or anatomical (neck ultrasound, thoracic CT, bone MRI) imaging methods can be performed when Tg increases in order to show residual/recurrent disease. In recent years, new hybrid equipments integrating both a gamma camera and CT scan (SPECT/CT) have been commercialized while positron emission tomography cameras associated with CT (PET/CT) have been installed on the whole French territory. These equipments, which allow us to directly correlate functional and anatomical images, greatly improve the interpretation of planar scintigraphy or that of PET alone. Hybrid imaging enables us to precisely localize scintigraphic foci and most often, to immediately verify whether they correspond to tumour lesions. The aim of this article is to review the role of SPECT/CT and PET/CT in the management of patients with DTC in 2010. (authors)

Introduction Le cancer du sein représente un problème de santé publique majeur au Maroc. C'est le premier cancer chez la femme. L'objectif de ce travail était d'évaluer les connaissances des médecins généralistes (MG) en matière de dépistage du cancer du sein dans la préfecture de Mohammedia Maroc. Méthodes Nous avons mené une étude transversale, descriptive, exhaustive incluant les 97 MG exerçant dans les établissements de soins de santé de base du secteur public et privé de la province de Mohammedia. Résultats Le taux de participation était de 87%. L'âge moyen des MG était de 49,6 ± 8,1. Quatre-vingt pour cent (n=55) des MG ont donné une incidence incorrecte, 77,6% (n=85) ont reconnu l'existence d'un plan national de prévention et de contrôle du cancer (PNPCC) au Maroc, et 67,1 des MG ont rapporté l'existence d'un registre du cancer au Maroc. Le secteur d'activité était associé significativement avec les connaissances des MG sur le PNPCC et sur l'existence d'un guide de détection précoce du cancer du sein avec respectivement (p=0,003 et p=0,001). Une association significative entre l'ancienneté et l'existence d'un guide de détection précoce du cancer du sein et d'un registre du cancer du sein a été retrouvée avec (respectivement p=0,005 et p=0.002). Conclusion À la lumière de ces résultats il faudra renforcer les connaissances et les pratiques des MG par la promotion de la formation initiale et continue sur le dépistage. PMID:27800098

106 patients, 114 W, 27 M, were thyroidectomized for differentiated thyroid cancer (follicular 29.3% - papillary 54.3%) with different stages of gravity (N O: 48.2% - N 1: 32.8% - N 2: 19%). Neck dissection was used in cases of involved nodes. One or several doses of 131 I were given to 126 subjects, 106 patients were treated with L thyroxine (LT4) (mean daily dose: 2.5 {mu}g/kg BW). 23 patients presenting intolerance to LT4 with non suppressed TSH for 13 of them were treated by an association of tiratricol (TRIAC) + LT4. The follow up included a yearly check up involving clinical examination, plasma thyroglobulin (Tg) and thyroid stimulating hormone (TSH) assessment, neck ultrasonography and X ray of the chest. Therapy was stopped for 4 weeks in cases with Tg above its detectable value and a total body scan performed with Tg and TSH controls. The mean duration of follow up was 94.5 {+-} 67.7 months and extended to more than 5 years for 61% of the patients. We observed 22 relapses of the tumor with 4 deaths. Age less then 45 years, appears as the best factor of prognosis. 2 groups of patients were compared to evaluate the incidence of TSH suppression on the relapse free survival (group 1 n = 30 with a TSH {<=} 0.10 mU/1 and group 2 n = 15 with a TSH always > 1 mU/1 during the follow up). The relapse free survival was shorter in group 2 (p 0.01). Association of TRIAC with LT4 leads to a reduction of the daily dose of LT4 (m 25{mu}g/day) with a significant improvement of TSH suppression and clinical tolerance. In conclusion, TSH suppression improves the prognosis in thyroidectomized patients for differentiated carcinoma. Association of TRIAC with LT4 seems able to approve TSH suppression and therapeutic tolerance. (authors). 40 refs., 5 tabs.

El Mansouri, Souleimane

Dans le domaine viscoelastique lineaire (VEL, domaine des petites deformations), le comportement thermomecanique du bitume et du mastic bitumineux (melange uniforme de bitume et de fillers) a ete caracterise au Laboratoire des Chaussees et Materiaux Bitumineux (LCMB) de l'Ecole de technologie superieure (ETS) avec l'appui de nos partenaires externes : la Societe des Alcools du Quebec (SAQ) et Eco Entreprises Quebec (EEQ). Les proprietes rheologiques des bitumes et des mastics ont ete mesurees grâce a un nouvel outil d'investigation appele, Rheometre a Cisaillement Annulaire (RCA), sous differentes conditions de chargement. Cet appareil permet non seulement de solliciter des eprouvettes de tailles importantes par rapport a celles utilisees lors des essais classiques, mais aussi d'effectuer des essais en conditions quasi-homogenes, ce qui permet de donner acces a la loi de comportement des materiaux. Les essais sont realises sur une large gamme de temperatures et de frequences (de -15 °C a 45°C et de 0,03Hz a 10 Hz). Cette etude a ete menee principalement pour comparer le comportement d'un bitume avec celui d'un mastic bitumineux dans le domaine des petites deformations. neanmoins, dans une seconde perspective, on s'interesse a l'influence des fillers de verre de post-consommation sur le comportement d'un mastic a faibles niveaux de deformations en comparant l'evolution des modules complexes de cisaillements (G*) d'un mastic avec fillers de verre et un mastic avec fillers conventionnels (calcaire). Enfin, le modele analogique 2S2P1D est utilise pour simuler le comportement viscoelastique lineaire des bitumes et des mastics bitumineux testes lors de la campagne experimentale.

Décrire les caractéristiques épidémiologiques et histo-pathologiques des tumeurs malignes du sein au Cameroun. Il s'agissait d'une étude rétrospective descriptive portant sur les tumeurs malignes du sein, colligées, dans les registres des différents laboratoires d'Anatomie Pathologique publiques et privés repartis dans cinq régions (centre, littoral, Ouest, Nord-ouest, Sud-ouest), pendant une période de 10 ans (2004-2013). Les paramètres étudiés étaient la fréquence, l’âge, le sexe, la localisation, le type et le grade histologique, et les récepteurs hormonaux. Un total de 3044 cas de cancers du sein a été recensé, soit une fréquence annuelle de 304,4 cas en moyenne. Le sexe féminin était le plus représenté avec 2971 cas (97,60%) et les hommes avec 73 cas (2,40%), soit un sexe ratio (H/F) de 0,02. L’âge moyen des patients était de 46±15,87 ans, avec des extrêmes de 13 et 95 ans. Selon la localisation, le sein gauche était atteint dans 1244 cas (52%) et le sein droit dans 1115 cas (47%). Au plan histologique, on retrouvait essentiellement des carcinomes avec 96,50% des cas, des sarcomes 1,39%, des lymphomes 1,07% et la maladie de Paget du mamelon, 1,03%. Les tumeurs épithéliales étaient infiltrantes dans 2049 cas (84,46%), avec une prédominance du carcinome canalaire infiltrant (1870 cas) et non infiltrantes dans 377 cas (15,54%). Le grade histo-pronostic de SBR avait révélé une prédominance du grade II dans 66% des cas. Les cancers du sein restent une pathologie fréquente au Cameroun et atteignent principalement la population féminine en âge de procréer. Ils sont caractérisés par la prédominance du carcinome canalaire infiltrant. PMID:26523182

Study of some continuous spectra produced by nuclear reactions with light nuclei; Etude de quelques spectres continus produits par reactions nucleaires avec des noyaux legers

Energy Technology Data Exchange (ETDEWEB)

Marquez, L

1966-07-01

The continuous spectra coming from several nuclear reactions with light nuclei were measured. The spectra can be explained by a two-step reaction mechanism; however, the reactions produced by {sup 6}Li are different. A mechanism was proposed to explain their spectra based on the following assumptions: {sup 6}Li makes a nuclear molecule with the target which subsequently breaks up in such a way that an {alpha} particle comes out with the kinetic energy that it has in the molecule. The calculated spectra and those measured are in good agreement. (author) [French] Nous avons mesure les spectres continus produits dans plusieurs reactions nucleaires avec des noyaux legers. A l'exception des spectres produits par {sup 6}Li, on a trouve qu'on pouvait expliquer ces spectres par le mecanisme des reactions en deux etapes. Nous avons propose un mecanisme pour expliquer les spectres produits par {sup 6}Li. On suppose que {sup 6}Li forme une molecule nucleaire avec la cible qui eclate ensuite de facon telle qu'une particule alpha de la molecule sort avec l'energie cinetique de son mouvement propre dans la molecule. Les spectres calcules avec ces hypotheses et les spectres mesures sont en bon accord. (auteur)

Le système de l'harmonie de Rameau dans sa correspondance avec d'Alembert et Rousseau

Directory of Open Access Journals (Sweden)

Stefanović Ana M.

2002-01-01

Full Text Available (francuski L'article examine la correspondance polémique de Rameau avec d'Alembert et Rousseau, entretenue dans la sixième décénie du XVIIIe siècle. Le système de l'harmonie de Rameau y est affronté à deux défis contradictoires: d'un côté, à la provocation d'absolutisation du système venant de son intériorité-même, et de l'autre, à une nouvelle conception de l'autonomie musicale, conçue sur le geste anarchique et destructif envers lui. Tandis que, de la polémique avec d'Alembert, le système vient de ressortir assuré et renforcé, soutenant la suprématie de la musique dans le champ théorique, la polémique avec Rousseau démontre que l'autonomie scientifique n'entraîne pas de soi l'isolation de la musique dans le domaine esthétique. Fondé sur le réseau cohérent de ses propres règles, le système musical est apte de se plier, de se modifier sous l'influence de ce qui lui est "extérieur": du sens contenu dans des énoncés linguistiques. L'idée de représentation musicale est alors modifiée dans la direction d'une réconcilliation possible de la raison (cartésienne et de l'imagination créatrice, du général et du particulier, de la norme et de l'individualité, dans la mesure où le système musical devenant analogue au système linguistique, en tant que "langue en action" participe chaque fois dans l'événement de sa propre création.

Reflexions sur l' origine du passif forme avec venire

Directory of Open Access Journals (Sweden)

M. Regula

1958-12-01

Full Text Available Le but que nous nous sommes proposé dans cette étude, est assez modeste: Il s'agit de combler une lacune de la réfutation des raisons alléguées par K. v. Ettmayer contre venire + participe passé comme base primaire du passif1 et d'expliquer l'origine de cette formule. Dans la ZRPh XLI, 42 ss., K. v. Ettmayer a fait les hypothèses suivantes: venitur ereptum puellam > *venit ereptum puellam > puella venit erepta. Cette dérivation de la périphrase verbale du passif nous paraît trop scrupuleuse et diffuse. On sait que ce savant a fait deux objections contre l'explication la plus naturelle de la formation du passif avec venire . La première, c'est que la séquence venire + p. p. ne pouvait être attesté par le latin. Mais, voici des exemples qui servent de contreargument.

« Faire clair et vif avec des éléments complexes »

Directory of Open Access Journals (Sweden)

Cordula Reichart

Full Text Available Avec le roman Salammbô et le conte Hérodias, Flaubert se tourne vers l’Antiquité préchrétienne afin de montrer à la modernité, sur le mode « clair et vif », sa complexité, son implication dans des discours de pouvoir religieux et historiographiques. C’est en se penchant sur les sources historiographiques et bibliques que Flaubert décline les stratégies d’exclusion et de surécriture, mettant au jour ce qu’elles refoulent, non pas sous forme de signification alternative, explicite, mais en tant que défiguration, réalisation littérale des corps et des signes.Avec Salammbô, Flaubert écrit une histoire du salut. Carthage, représentée dès le début par la protagoniste Salammbô en tant que pars pro toto, expose les figures cachées de Rome, à laquelle est liée, aussi et surtout, la promesse chrétienne de salut. Dans le nom de Salammbô Flaubert réécrit l’origine de cette figure en fait associée à la Rome chrétienne en s’appuyant sur l’exemple de l’histoire antique de Carthage.Dans Hérodias, Flaubert reprend le thème du triomphe de l’Orient annoncé par Renan et redouté par l’Église catholique. Un danger, pourrait-on dire, qui se réalise dans la figure d’Hérodias et qui est conjuré avec la décapitation de Jean. Dans son rapport inversé avec les textes de référence, Hérodias démasque les ambitions et la volonté hégémonique du modèle de pouvoir propre à l’Église en Orient. La translatio de l’empire romain est radicalisée au moyen de la figure d’Aulus. Aulus peut faire l’objet d’une lecture performative en tant que début et fondement de l’histoire française du salut comme histoire romaine de la perversion.In the novel Salammbô and the short story Hérodias, Flaubert turns to pre-Christian antiquity in order to present modernity its complexity, its entwinement in religious and historiographical discourses of power, in a « clair et vif » manner.

L'angiomyolipome rénal est une tumeur qui est reconnue bénigne. Elle présente trois composantes différentes: musculaire, vasculaire et graisseuse, dont la distribution est variable. Le diagnostic repose sur la mise en évidence de la composante graisseuse intra-tumorale en TDM ou IRM. Exceptionnellement la tumeur peut avoir un caractère agressive avec extension locorégionale et veineuse (la veine rénale et la veine cave inferieure). Nous présentons une observation d'une patiente âgée de 37 ans présentant un Angiomyolipome rénal volumineux avec extension à la veine rénale. PMID:29599888

This instrument, derived from the recording {gamma} spectrograph, gives better definition of photoelectric peaks by elimination of pulses caused by {gamma} photons incompletely absorbed in the scintillator (Compton effect). This system uses an original method devised by Peirson: the spectrum, devoid of photoelectric peak, supplied by a detector equipped with an anthracene scintillator, is cut off from the spectrum provided by a conventional detector equipped with a Nal (T1) scintillator. The regulation of the mechanical system, detector support and source allows the detection yields to be adjusted. The electronic system is identical in presentation with that of the recording spectrograph. (author) [French] Cet appareil derive du spectrographe {gamma} enregistreur permet d'obtenir une meilleure definition des pics photoelectriques, par elimination des impulsions provenant des photons {gamma} incompletement absorbes dans le scintillateur (effet Compton).

Le reglage de l'ensemble mecanique, support des detecteurs et de la source, permet d'ajuster les rendements de detection.

Mesure asymétrie avant-arriere des quarks lourds a LEP1 avec le détecteur OPAL

CERN Document Server

Lafoux, H

A partir de l'ensemble des données accumulées par OPAL au cours de la première phase de fonctionnement du LEP, nous avons mesuré l'asymétrie avant-arrière des quarks b et c au voisinage du pic du Zo. Utilisant une méthode traditionnelle, basée sur la détection des leptons produits dans les désintégrations semi-leptoniques des hadrons lourds, nous avons cherché à optimiser chaque étape de la mesure, en mettant en œuvre les algorithmes les plus appropriés. Le recours aux réseaux de neurones artificiels s'est en particulier avéré d'une grande utilité lorsque le problème à résoudre impliquait la prise en compte simultanée de multiples sources d'informations, d'origine et de nature très variées. Nos résultats sont en bon accord avec ceux des autres mesures effectuées à LEP et compatibles avec les prédictions du Modèle Standard pour un quark top de 174 ± 31 GeV/c2 et un boson de Higgs de masse comprise entre 60 et 1000 GeV/c2

Full Text Available Depuis la découverte du virus, les manuels en soins infirmiers incluent la notion de VIH/sida pour qu’elle soit transmise dans la formation de premier cycle. Cependant, les écrits dévoilent l’existence d’un écart entre cette formation et les compétences requises pour prodiguer des soins aux personnes vivant avec le VIH. Conscientes des lacunes de la formation initiale en VIH/sida et qui, à ce jour, n’ont pas été explorées dans les manuels, nous avons réalisé une analyse qualitative de contenu de 18 manuels de médecine-chirurgie. Les résultats de cette étude ont dévoilé trois catégories : les représentations du VIH, des personnes vivant avec le VIH et des soins. La première catégorie renvoie à la façon dont on raconte l’histoire du VIH et parle du virus ainsi que la façon dont on décrit la maladie et conceptualise la transmission. La deuxième correspond aux personnes qui sont à risque de contracter le VIH, qui vivent avec le VIH et à la façon dont on les représente. La troisième réfère à la représentation des types de soins, leurs objectifs et les enjeux qui y sont associés.

As during the treatment by co-precipitation with calcium carbonate of liquid radioactive residues, a partial decontamination can be obtained by simply agitating an already formed radioactive sludge with the effluent to be processed, the authors study whether it would be possible to first perform a co-precipitation with a lower dose of calcium carbonate and then to complete decontamination by agitating with an adequate quantity of sludge stored during preceding operations. The authors report the study of the influence of reactant quantity on the chemical treatment efficiency, of the evolution of the activity of a radioactive residual solution in contact with a precipitate, of the cleaner element, of a precipitate reuse, of the technological and economic aspects, and of another possibility of reduction of the precipitate volume [French] Dans le traitement par coprecipitation avec le carbonate de calcium des residus radioactifs liquides, une decontamination partielle peut etre obtenue en agitant simplement une boue radioactive deja formee avec l'effluent a traiter.

The reaction of uranium and plutonium carbides with austenitic steels has been studied between 650 and 1050 deg. C using UC, steel and (UPu)C, steel diffusion couples. The steels are of the type CN 18.10 with or without addition of molybdenum. The carbides used are hyper-stoichiometric. Tests were also carried out with UCTi, UCMo, UPuCTi and UPuCMo. Up to 800 deg. C no marked diffusion of carbon into stainless steel is observed. Between 800 and 900 deg. C the carbon produced by the decomposition of the higher carbides diffuses into the steel. Above 900 deg. C, decomposition of the monocarbide occurs according to a reaction which can be written schematically as: (U,PuC) + (Fe,Ni,Cr) {yields} (U,Pu) Fe{sub 2} + Cr{sub 23}C{sub 6}. Above 950 deg. C the behaviour of UPuCMo and that of the titanium (CN 18.12) and nickel (NC 38. 18) steels is observed to be very satisfactory.

Uranium and plutonium carbides react with nitrogen during the grinding process preceding the final sintering. The reaction occurs even in argon atmospheres containing a few percent of residual nitrogen. The resulting contamination is responsible for the appearance of an equivalent quantity of higher carbide in the sintered products; nitrogen remains quantitatively in the monocarbide phase. UC can be transformed completely into nitride under a nitrogen pressure, at a temperature as low as 400 C. The reaction is more sluggish with PuC. The following reactions take places: UC + 0,8 N{sub 2} {yields}> UN{sub 1.60} + C and PuC + 0,5 N{sub 2} {yields} PuN + C. (authors) [French] Les carbures d'uranium et de plutonium reagissent avec l'azote au cours du broyage qui precede le frittage final. Cette reaction est sensible meme sous des atmospheres d'argon ne contenant que quelques pour cent d'azote. Cette contamination se traduit sur les produits frittes par l'apparition d'une quantite equivalente de carbure superieur, l'azote restant fixe quantitativement dans la phase monocarbure. On peut transformer entierement UC en nitrure par action de l'azote sous pression des 400 C. La reaction est plus difficile avec PuC. Les reactions sont les suivantes: UC + 0,8 N{sub 2} {yields} UN{sub 1.60} + C et PuC + 0,5 N{sub 2} {yields} PuN + C.

Pompe de chaleur fonctionnant avec un mélange de fluides Heat Pump Operating with a Fluid Mixture

Full Text Available Lorsqu'une pompe de chaleur échange de la chaleur avec des fluides extérieurs, dont la température évolue au cours de l'échange, il est possible d'augmenter le coefficient de performance en utilisant comme fluide de travail un mélange non-azéotropique qui se vaporise et se condense suivant une évolution de température parallèle à celle du fluide extérieur avec lequel s'effectue cet échange. L'utilisation de mélanges dans les pompes de chaleur a été étudiée, d'une part, au moyen de modèles de simulation sur ordinateur et, d'autre part, au moyen d'essais expérimentaux. Différentes applications ont été examinées à la fois dans le domaine du chauffage résidentiel et dans le domaine industriel. Whenever heat is recovered and delivered, the coefficient of performance of a heat pump can be increased by using a fluid mixture selected to have a temperature variation, during the vaporization and condensation stages, parallel to that of the outside fluid with which the heat exchange takes place. Such a solution was investigated both theoretically and experimentally. It has been shown that significant savings can be expected, ranging up to 50% of the energy consumption of conventional heat pumps in some cases. Various applications for home and industrial heating have been examined, and the economic prospects have been found to be satisfactory. Further work is needed to develop such heat pumps on a commercial basis.

Puisque l’infection par le VIH/SIDA est une maladie du système immunitaire, elle influence de plusieurs manières l’état nutritionnel du patient. Une nutrition hyper calorifique et hyper protéinée saine, variée et adaptée aux besoins de l’organisme est une condition indispensable pour rester longtemps en forme en cas d’infection par le VIH/SIDA. Elle permet en outre de garder un poids normal pendant la phase asymptomatique de l’infection et d’augmenter son poids pendant la phase symptomatique. Ceci a pour but de freiner l’évolution de l’infection vers le stade SIDA. Les personnes atteintes par le VIH/SIDA devraient en plus avoir une bonne hygiène de vie et exercer régulièrement une activité sportive modérée. Elles devraient mettre l’accent sur leur protection contre toute intoxication alimentaire et sur le renforcement de leur système immunitaire. Il est en outre important en plus du besoin en nutriments des personnes atteintes par le VIH/SIDA, de tenir compte de leur situation financière et culturelle, car en Afrique il existe sur ce point une très grande différence dans la population.

National audience; Les besoins en électricité sont croissants, cependant, les rejets thermiques industriels sont peu valorisés. La reconsidération des moteurs à apport de chaleur externe est un enjeu d'actualité pour la valorisation des rejets thermiques. Dans ces derniers, la phase de détente motrice offre des possibilités d'amélioration. L'idée ici est d'accompagner cette étape par un apport de chaleur par contact direct avec un fluide caloporteur.

Les politiques d’appui à l’agriculture familiale au Brésil : quelques éléments de comparaison avec le Maroc

Directory of Open Access Journals (Sweden)

Philippe Bonnal

2015-10-01

Full Text Available Au Brésil comme au Maroc, le secteur agricole est marqué par des différences extrêmes en termes de taille d’exploitation, ainsi que de niveaux d’équipement, de capitalisation et de techniques. L’article présente la politique brésilienne d’appui à l’agriculture familiale, et quelques éléments de comparaison avec les choix faits au Maroc. Les politiques agricoles brésiliennes proposent depuis une vingtaine d’années un appui spécifique aux exploitations familiales, avec notamment la constitution d’un ministère spécifique. De nombreux dispositifs d’appui à l’agriculture familiale ont été mis en place, dont notamment des crédits à taux préférentiel et des programmes d’achat de denrées agricoles pour les institutions publiques (écoles, hôpitaux, etc.. Dans les zones rurales particulièrement fragiles, des dispositifs permettent une coordination entre l’ensemble des politiques publiques concernant ces zones. Enfin, la conception et la mise en oeuvre de ces politiques publiques se font avec une forte implication des syndicats agricoles. Les politiques publiques brésiliennes et marocaines reconnaissent la dualité du monde agricole, mais cette dualité est définie par zone au Maroc, tandis qu’elle est fondée sur des caractéristiques explicites des exploitations au Brésil. Dans les deux pays, le coeur des politiques publiques d’appui aux exploitations familiales porte sur l’aide à l’investissement. Au-delà de ce coeur commun, les politiques brésiliennes ont plus spécifiquement développé des approches au niveau des territoires locaux et associent plus fortement qu’au Maroc les organisations professionnelles agricoles représentant l’agriculture familiale dans la conception de l’action publique. La comparaison des politiques agricoles au Maroc et au Brésil sur quelques éléments permet de souligner la forte étendue des choix qu’il est possible de considérer, pour définir des

Décrire notre stratégie diagnostique et thérapeutique dans les cancers du sein bilatéraux synchrones pendant la grossesse. L’âge gestationnel au moment du diagnostic du cancer était respectivement de 7; 21 et 25 semaines. Il s'agissait de stade IV et IIIA respectivement dans deux et un cas. Elles ont toutes bénéficié d'une chimiothérapie dans deux cas pendant la grossesse (6TEC et 3AC) et dans un cas après l'accouchement. Une mastectomie bilatérale a été réalisée dans un cas. Une patiente est décédée. Les autres étaient vivantes mais toutes métastatiques. Une hypotrophie fœtale a été notée dans un cas. Le diagnostic du cancer est tardif dans cette association. La chirurgie est faisable et le type de chirurgie serait seulement fonction du stade du cancer. La chimiothérapie est possible avec moins de complications fœtales aux deux derniers trimestres.

OBJECTIF : Les études ciblant les enfants nés avec le VIH se sont principalement intéressées à la période précédant l’annonce du diagnostic à l’enfant. L’objectif de cette étude est d’explorer les dynamiques de communication intrafamiliale suivant l’annonce du diagnostic. MÉTHODOLOGIE : Vingt-neuf jeunes (de dix à 18 ans) vivant avec le VIH depuis la naissance ont accordé des entrevues individuelles semi-dirigées portant sur : 1) le dévoilement du statut sérologique, 2) leurs relations familiales et 3) l’éducation sexuelle en milieu familial. Les témoignages ont fait l’objet d’une analyse de contenu. RÉSULTATS : Les jeunes ont appris en moyenne à l’âge de 11 ans leur diagnostic VIH+. La dynamique qui s’installe après cette annonce apparaît régie par le silence : les échanges qui s’ensuivent portent en majorité sur des questions relatives à la médication et à la prévention d’une transmission sexuelle du virus. Ce silence préserverait l’équilibre familial en occupant trois fonctions : protéger la mère d’un sentiment de culpabilité à l’égard de la transmission, assurer l’harmonie familiale, se sentir normal face aux autres. Le diagnostic de l’adolescent n’est généralement pas révélé à la famille élargie, préservant ainsi leur intégration au sein de la famille en les protégeant du rejet, de la trahison et du jugement. EXPOSÉ : Les fonctions du silence et du secret occupent une place stabilisatrice importante au sein de la famille. Toutefois, elles contribuent à isoler les adolescents d’une forme de soutien affectif dont ils ont pourtant besoin. Des pistes d’intervention sont suggérées. PMID:22851894

Les résultats obtenus montrent que l'héritabilité de la présence d'une forte pilosité sur les tiges et sur les pétioles est contrôlée par deux gènes assortis et indépendants. Les deux gènes dominants S et P confèrent aux plantes une importante pilosité sur les tiges et sur les pétioles tandis qu'un allèle dominant S-pp et ss-P confère aux plantes une pilosité respectivement abondante sur les tiges st sur les pétioles. Seuls les génotypes homozygotes sspp avec deux gènes récessifs produisent des plantes avec peu de poils sur les tiges et sur les pétioles. Les implications de ces résultats dans l'évolution de ces espèces sont discutées.

'une plaque plane avec aspiration. La paroi poreuse s'etend sur 1 m de longueur, a partir d'une distance de 1 m en aval du bord d'attaque. Le nombre de Reynolds d'epaisseur de la couche limite en l'absence d'aspiration est de l'ordre de 16,300. Le taux d'aspiration, defini comme le rapport a la vitesse generale de la vitesse normale a la paroi, est reglable de 0 a 2 pour cent. Le gradient de pression est controlable. On a determine en diverses positions et pour divers taux d'aspiration: avec des sondes de prise de pression totale, les profils de vitesse moyenne, avec des anemometres a fils chauds, analyseur spectral et correlateur, les intensites des differentes composantes des fluctuations turbulentes de vitesse, les spectres d'energie, les correlations. On deduit de ces mesures: le trace des lignes de courant, les valeurs des tensions de frottement visqueux et turbulent, du frottement local a la paroi, et du terme de production de l'energie turbulente, ainsi que des indications sur la dissipation de cette energie. Pour ces calculs, l'equation integree de conservations de la masse dans la couche limite a ete etablie. L'influence de l'aspiration sur la couche limite est importante: elle modifie profondement la forme des profils de vitesse moyenne, augmentant les tensions de frottement visqueux a la paroi, les diminuant ailleurs; elle diminue les intensites de turbulence longitudinale et transversale ainsi que les tensions de frottement turbulent et la production d'energie turbulente. Ces effets sont tres marques dans la zone interne de la couche limite. Par contre, l'etude des spectres d'energie indique que l'echelle de la turbulence, est peu modifiee, l'epaisseur de la couche limite ne diminuant que faiblement sous l'influence de l'aspiration. Les effets de l'aspiration peuvent etre apprecies en comparant le double du taux d'aspiration au coefficient de frottement a la paroi (supposee etanche); notables des que ce rapport depasse l'unite, ils deviennent tres importants

Full Text Available Dans cet entretien inédit, Jaques Guilhaumou parle sur la question du discours et de l´histoire dans la pensée de Michel Foucault en regardant telles questions à partir du belvédère de l’Analyse du Discours selon la perception française. Il commence en présentant un panorama de ses travaux plus actuels et souligne ensuite le rôle décisif de Foucault dans le établissement de une nouvelle relation entre le discours et l´histoire. Dans cette direction, il donne des détails sur quelques influences épistémologiques de la pensée foucaultienne qui viennent surtout de Nietzsche et Koselleck. Comme un grand étudiant de la pensée marxiste, Guilhaumou parle aussi sur le concept de l´ideologie et ses plusières métamorphoses conceptuelles dans autres champs jusqu´au moment de parler sur la question du pouvoir. Il parle quand même sur la problématique de l´analyse des images dans l´Analyse du Discours, une question favorable pour beaucoup des analystes du discours qui s´occupent avec le syncrétisme sémiotique des ses objets dans l´actualité. Enfin, il indique l´existence de une théorie du discours diluée dans la pensée du philosophe.

Introduction Beaucoup d'enfants vivant avec le VIH ont été infectés par leurs mères. Pour prévenir la transmission verticale les femmes doivent d'abord connaître leur statut sérologique VIH.L'objectif de cette étude était de déterminer la proportion de statut VIH inconnu à la naissance et d'identifier les facteurs associés. Méthodes C'est une étude transversale réalisée dans 10 structures sanitaires de Lubumbashi de Juin à Septembre 2010. La taille de l’échantillon était de 602 accouchées. Les statistiques descriptives usuelles et la régression logistique ont été utilisées. Résultats Parmi les accouchées, 52,5% ignoraient leur statut sérologique. Parmi elles, 62,9% accepteraient de faire le test VIH à la maternité. La proportion des femmes avec un statut sérologique VIH inconnu était significativement plus élevée chez celles qui n'avaient pas suivi de CPN (Odds Ratio ajusté (ORa) = 5,8; Intervalle de Confiance (IC) 95%: 1,7-19,8); chez celles qui avaient un bas niveau d'instruction (ORa = 1,5; IC 95%: 1,1-2,1) et chez celles qui ne savaient pas que la transmission verticale du VIH pouvaient se faire au moment de l'accouchement (ORa = 1,5; IC 95%: 1,0-2,4). Conclusion La proportion de femmes qui accouchent sans connaître leur statut sérologique au VIH est encore importante, malgré le fait que le dépistage du VIH soit proposé lors des CPN. Dans les zones à haute séroprévalence de VIH, aucune femme ne devrait accoucher sans être dépistée au VIH. Ce serait une opportunité manquée. PMID:22891083

Les individus face à l’événement « cancer » Individuals facing cancer : an acute crisis becoming chronical within the family and the workplace

Full Text Available Notre analyse porte sur les effets du cancer sur les temporalités collectives que sont la vie familiale et le travail. Cette pathologie a toujours engendré une crise biographique au moment de son apparition. Cependant sa chronicisation, produit de l’évolution de la cancérologie ces quarante dernières années, a modifié les effets sociaux qu’elle engendre. À part quelques cancers comme celui de l’œsophage, du foie ou du pancréas, le cancer n’est plus une maladie aiguë induisant une forte mortalité à court terme. Cependant, des traitements à l’issue incertaine peuvent souvent durer des années et se montrer handicapants et stigmatisants. Les temporalités collectives, partagées entre les malades et leur entourage, se disloquent, entraînant des disjonctions temporelles et l’isolement social du malade. La dimension écliptique de la maladie, avec ses rémissions et ses rechutes, engendre des répétitions de la crise biographique.In this article, we present arguments on the impact of cancer on the collective experience of time within two main social institutions, family and the workplace. This disease always provokes a biographic crisis when it appears. Nevertheless, as medical technology progresses, cancer is becoming a chronic disease, and the social effects of cancer are changing. It is no longer the same disease with a short-term risk of death. Treatments can last for years with uncertain results and induce handicap or social stigma. The collective experiences of time, shared between the sick person and her family and friends, tend to break up, entailing time breaks and leading to the social isolation of the patient. The ecliptic dimension of the disease, with its remissions and relapses, gives rise to repeated biographic crisis.

Head trauma and CT

International Nuclear Information System (INIS)

Samejima, Kanji; Yoshii, Nobuo; Tobari, Chitoshi

1979-01-01

In our cases of acute and subacute subdural hematoma, the use of CT was evaluated. In our department of surgery, acute subdural hematoma was found in 46 of 388 patients of head trauma who underwent CT. Acute subdural hematoma, like epidural hematoma was usually visualized as a high-density area along the cranial inner table, and this was easily differenciated from epidural hematoma because of difference in shape from the other. The picture of acute subdural hematoma was occasionally confused with that of intracerebral hematoma or cerebral contusion. Single use of CT does not differenciate subacute subdural hematoma from chronic subdural hematoma. However, CT usually visualized acute hematoma as a high-density area, showing the extent of hematoma. Comparison of the thickness of hematoma with the axis deviation of the median part such as the 3rd cerebral ventricle suggested severity of cerebral edema. CT also revealed bilateral or multiple lesions of cerebral contusion or intracerebral hematoma. (Ueda, J.)

Full Text Available The reduction of acid gas content in combustion or incineration flue gases can be carried out by reaction with dry, fine alkaline sorbents such as calcium oxide or calcium hydroxide. In the present work, in addition to the thermodynamic study of the different reactions involved in the dechlorination process, an experimental study to identify the reaction products by means of X-ray diffraction, electron microscopy and thermogravimetry has been carried out. It has been shown that the reaction of hydrochloric acid with hydrated lime leads to the formation of not only calcium chloride but calcium hydroxichloride. La diminution de la teneur en gaz acides dans les effluents provenant des unités de combustion ou d'incinération peut être accomplie en faisant réagir ces gaz polluants avec des absorbants alcalins tels que l'oxyde ou l'hydroxyde de calcium. Dans cet article, à l'étude thermodynamique des différentes réactions mises en jeu durant le processus de déchloruration, s'ajoute une étude expérimentale menant à l'identification des produits finaux en utilisant la diffraction X, la microscopie électronique ainsi que la thermogravimétrie. A l'issue de cette étude, il a été montré que la réaction de Ca(OH2 avec HCl entraîne la formation non seulement de CaCI2 mais aussi CaCIOH.

Full Text Available La sociologie à Craiova étant une spécialité en matière d’offres de formation dans les trois cycles de l'enseignement supérieur: licence, master et doctorat, elle est aussi une pratique, ayant plus de 19 ans d'activité et d'expérience. Le nombre de projets de recherches doctorales et poste doctoraux réalisé et en cours de réalisation, justifie sa notoriété et de son appellation «L'école Sociologique de Craiova», notamment avec des partenaires pratiquant une sociologie d'action telle que l'Académie Roumaine et l'Institut Social Olténie. L'école sociologique de Craiova fait revivre la tradition sociologique roumaine et continue dans la lignée de la tradition de l'école Gustiènne. Il faut également noter que l'orientation des recherches sociologiques «Craiovienne» a pour objectif d'assurer un équilibre entre l'approche fondamentale et la recherche action. Dans ce qui suit, nous présenterons l’école sociologique de Craiova en mettant l’accent sur son fondateur, ses préoccupations, la recherche etc.

Les nodules thyroïdiens sont très fréquents et moins de 10% d'entre eux sont malin. Ils posent un véritable problème diagnostique et thérapeutique surtout par rapport à leur nature bénigne ou maligne. L’étude de certains facteurs cliniques et paracliniques de présomption de malignité permet de bien codifier la stratégie thérapeutique. Le but de ce travail est d’étudier les facteurs prédictifs de malignité des goitres nodulaires et comparer nos résultats à ceux de la littérature. Il s'agit d'une étude rétrospective à propos de 500 cas de goitres nodulaires opérés au service d'Oto-rhino-laryngologie (ORL) et Chirurgie cervico-faciale (CCF) de l'hôpital militaire Avicenne de Marrakech entre 2006 et 2012. Le pourcentage de cancers a été de 6,8%. L’âge moyen de nos patients était de 46 ans, avec une sex-ratio de 5 (F/H). A la palpation cervicale; le caractère dure du nodule a été constaté dans 94,4% des cas de cancer, avec des limites irrégulières dans 64,70% des cas de cancer. Trois nodules étaient fixes et ils étaient tous malins. Les adénopathies cervicales ont été constatées chez 8 malades dont 7 présentaient des cancers. A l’échographie, 61,8% des nodules malins présentaient un aspect hypoéchogène, avec des contours flous dans 88,24% des cas. La vascularisation intra nodulaire était présente dans 35,3% de ces cas des cancers avec des microcalcifications chez 55,9% d'entre eux. Le halo hypoéchogene périnodulaire était incomplet dans 73,5% des cas de cancer. Nos patients étaient en euthyroïdie dans 84,6% des cas. Les facteurs prédictifs de malignité d'un goitre nodulaire, étaient donc dans notre étude d'abord cliniques: l’âge supérieur à 60 ans, la consistance dure du nodule, sa fixité, son caractère irrégulier et mal limité à la palpation, ainsi que la présence d'adénopathie(s) cervicale(s) à l'examen; et échographiques: le caractère hypoéchogène, les limites floues, la présence de

Résumé Objectif Offrir aux médecins de famille un résumé des recommandations fondées sur les données probantes pour guider les soins aux survivantes traitées pour le cancer du sein. Qualité des données Une recherche documentaire a été effectuée dans MEDLINE entre 2000 et 2016 à l’aide des mots-clés anglais suivants : breast cancer, survivorship, follow-up care, aftercare, guidelines et survivorship care plans, en se concentrant sur la revue des lignes directrices publiées récemment par les organismes nationaux de cancérologie. Les données étaient de niveaux I à III. Message principal Les soins aux survivantes comportent 4 facettes : surveillance et dépistage, prise en charge des effets à long terme, promotion de la santé et coordination des soins. La surveillance des récidives ne se traduit que par une mammographie annuelle, et le dépistage d’autres cancers doit suivre les lignes directrices basées sur la population. La prise en charge des effets à long terme du cancer et de son traitement aborde des problèmes courants tels la douleur, la fatigue, le lymphœdème, la détresse et les effets indésirables des médicaments, de même que les préoccupations à long terme comme la santé du cœur et des os. La promotion de la santé met en relief les bienfaits de l’activité chez les survivantes du cancer, avec l’accent mis sur l’activité physique. Les soins aux survivantes sont de meilleure qualité lorsque divers services et professionnels de la santé participent aux soins, et le médecin de famille joue un rôle important dans la coordination des soins. Conclusion Les médecins de famille sont de plus en plus souvent les principaux fournisseurs de soins de suivi après le traitement du cancer du sein. Le cancer du sein doit être considéré comme une affection médicale chronique, même chez les femmes en rémission, et les patientes profitent de la même approche que celle utilisée pour les autres affections chroniques en

Doxorubicin (Dox) is known as anticancer drug commonly used for cancer treatment. Eurycoma longifolia Jack or Pasakbumi was reported to have chemopreventive effect. In cancer patients, there are some dysfunctions of blood parameter, therefore some hematologic tests are needed to monitor cancer patients. In this study, the effects of combination of ethanolic extract of E. longifolia Jack (EEE) and Dox on hematologic profiles were investigated in rats injected by DMBA. Rats were divided into eight groups. Group I was normal group; Group II, rats were treated with extract dose 100 mg/kgbw; Groups III, IV, V, VI, VII and VIII, rats were treated with Dox, DMBA, DMBA+Dox, DMBA+EEE, DMBA+Dox +EEE, and Dox+EEE, respectively. DMBA administration orally was conducted twice a week for 5 weeks. At 16th week of treatments, bloods were taken from orbitalis sinus for hematologicals profile (levels of Hb, erytrocyte, hematocrite, leukocyte, MCV, MCH, and differencial leucocyte count) measurements. These data were analyzed by one way ANOVA followed by LSD test. DMBA administration significantly decreased the hematological profiles compared to the normal group, except in lymphocyte level. Rats treated with extract and extract+Dox were able to increase the hematological profile compared to rats given by DMBA only. Based on these findings it can be concluded that the combination of EEE and Dox potentially increase hematological profile of rats given by DMBA.

L’Amleto d’Arrigo Boito : deux versions énigmatiques avec Ducis et Dumas en dialogue Arrigo Boito’s Amleto: Two Enigmatic Versions Reversing Ducis and Changing Dumas

Full Text Available Le XIXe siècle est caractérisé par la redécouverte de Shakespeare. Cet article présente un exemple complexe de la réception de Shakespeare en France et en Italie: Hamlet a été à plusieurs reprises traduit et adapté à la scène et à l’opéra. Les traductions étaient pourtant loin d’être fidèles, ce qui n’était par contre pas le cas en Allemagne, si l’on pense à la traduction toujours apprécié des frères Schlegel. Ducis, par exemple, présente une histoire tout à fait incompatible avec le chef-d’œuvre de Shakespeare. Aussi Dumas père, bien qu’aidé par un traducteur, ne suit pas du tout l’original. Pourtant, ces deux versions, de même que leurs autres traductions, conditionneront longtemps la réception de Shakespeare dans les pays de l’Europe latine. Arrigo Boito offrira une version tout à fait autonome de l’Amleto, une désécriture d’auteur qui dialogue avec la version de Ducis, de Dumas, mais aussi avec les vraies traductions de Paul Meurice et de François-Victor Hugo.The 19th century is characterized by the rediscovery of Shakespeare. In this article, we will trace one complex example of Shakespeare’s reception in France and in Italy. Hamlet had been translated and adapted for the stage and for the opera several times. However, from the very beginning of the 18th century, authors like Ducis simply rewrote from scratch totally unauthentic versions which (misguided most French and Italian reception of Shakespeare. In the 19th century, Dumas offered a new and far more interesting interpretation which would be even more seminal for Latin Europe. Arrigo Boito’s Amleto dialogues in a rather astonishing and surprisingly modern way with the Dumas version of Hamlet, taking into account the more recent translations by François-Victor Hugo and Paul Meurice. As a result, the tragedy of the Danish prince is completely rewritten and deconstructed. As is often the case, Boito prefers to be the dwarf that

Using Tablet Computers with Elementary School Students with Special Needs: The Practices and Perceptions of Special Education Teachers and Teacher Assistants / Utilisation des tablettes électroniques avec des enfants d’école primaire à besoins spéciaux

Full Text Available Twelve special education teachers and teacher assistants who have instructional experience using iPads with children with special needs completed a survey that queried their practices and perceptions. In general, teachers and assistants were extremely positive about the value of iPads for children with special needs, particularly for children with autism, attention deficits and limitations of fine motor control. Special education teachers and teacher assistants reported most frequently using iPads to promote student language and literacy skills, although mathematics learning activities were also commonly reported. Enhanced student motivation was the most frequently reported benefit of using tablet computers in school followed by instructional planning advantages. Tablet computers appear to have the potential to be an essential aspect of individual program plans. Teaching tasks might reasonably include downloading and organizing specific applications on specific children’s tablets and professional development might increasingly focus of evaluation of tablet applications. Douze professeurs en éducation spéciale et aides-enseignants utilisant les iPads dans leur enseignement avec des enfants à besoins spéciaux ont rempli un questionnaire relatif à leurs pratiques et à leurs perceptions. En général, les enseignants et les aides-enseignants se sont révélés extrêmement positifs quant à la valeur des iPads pour les enfants à besoins spéciaux, en particulier pour les enfants avec autisme, avec un déficit d’attention et avec un contrôle limité de la motricité fine. Le plus souvent, les enseignants en éducation spéciale et les aides-enseignants ont indiqué avoir utilisé les iPads pour améliorer les compétences linguistiques et de littératie des élèves, bien que des activités d'apprentissage des mathématiques aient aussi été mentionnées fréquemment.

Full Text Available Puisque la gestion d’une situation de santé serait quasi impossible sans que le patient acquière certaines compétences, ce texte explore les perceptions des patients pouvant influencer leur autonomisation en situation d’éducation tertiaire et identifie des stratégies potentiellement autonomisantes pour les adresser. L’approche synthèse interprétative critique fût utilisée. Trois perceptions des patients sont résumées : la perception d’être partenaire avec les professionnels, la perception de la compréhension de leur état et la perception de l’influence ou du contrôle de leur situation. Identification de stratégies de nature éducative et comportementale. Les perceptions des patients démontrent qu’ils ne se sentent pas aussi autonomisés que les professionnels pensent, alors il est recommandé de reconnaître les perceptions qui nuisent à l’autonomisation, ainsi que des stratégies pour les gérer. Ceci inclut la considération du niveau de littératie en santé du patient ainsi que l’utilisation accrue d’outils validés avec des méthodes qualitatives auprès de populations variées.

We have assessed the diagnostic value of sup(99m)Tc-N-pyridoxyl-5-methyltryptophan (sup(99m)Tc-PMT) hepatobiliary scintigraphy in 28 patients with hepatocellular carcinoma (HCC) who had obvious filling defects on sup(99m)Tc-phytate liver scintigram. Uptake of sup(99m)Tc-PMT in obvious defects on sup(99m)Tc-phytate liver scintigram was observed in 16 out of 28 patients (57.1 %). Most of HCC with sup(99m)Tc-PMT uptake were histologically well-differenciated. However, well-differenciated HCC did not always take up sup(99m)Tc-PMT. No correlation was observed between sup(99m)Tc-PMT uptake in the tumor and levels of serum alpha-fetoprotein. Patients with high alpha-fetoprotein level (>3000 ng/ml) were only 9 patients (32.1 %) in our study. By the combined results of sup(99m)Tc-PMT hepatobiliary scintigraphy and alpha-fetoprotein level (>3000 ng/ml), diagnostic rate for HCC was markedly elevated up to 75 %. Therefore, it is considered that sup(99m)Tc-PMT hepatobiliary scintigraphy is clinically useful for specific diagnosis of HCC. Furthermore, it provides the information for invasion of HCC into the bile duct. (author)

Dans cette étude, nous avons utilisé le risque attribuable dans la population (RAP pour estimer le fardeau des cancers attribuables à l’excès de poids chez les adultes canadiens (de 25 ans ou plus en 2010. Méthodologie : Nous avons estimé les RAP en utilisant des estimations du risque relatif (RR tirées du Continuous Update Project du World Cancer Research Fund International, des estimations du surpoids et de l’obésité fondées sur l’IMC tirées de l’Enquête sur la santé dans les collectivités canadiennes de 2000-2001 (surpoids : 25,00 à 29,99 kg/m2; obésité : 30,00 kg/m2 et plus et nous avons utilisé les nombres de cas de cancer figurant dans le Registre canadien du cancer.

An increase in the incidence of thyroid cancer in children has been reported since 1990 in areas of Belarus, Russia and Ukraine which have been highly contaminated during the Chernobyl accident in 1986. A similar increase is now observed in young adults in the same areas. In France, thyroid cancer is characterized by low occurrence and good prognosis. However, the incidence of thyroid cancer has been increasing for more than 20 years, and in 1986, the Chernobyl cloud of radioactive dust crossed the French territory. Thus, the National institute for public health surveillance (I.n.V.S.) carried out several studies to evaluate whether the incidence increase in thyroid cancer is related to radiation exposure from the Chernobyl accident. Since 2000, the I.n.V.S. is in charge of a national multidisciplinary approach involving a wide range of public health actors, including the French network of cancer registries (Francim). Since 2003, the I.n.V.S. has been working on improving the surveillance system according to the actions described in the national cancer plan 2003-2007. The I.n.V.S. has increased its financial contribution to cancer registries including the national registry of solid tumors in children, which was created in 2000. The Institute is also working on the implementation of a multi source system for the national cancer surveillance in link with cancer registries. For the twentieth anniversary of the Chernobyl accident, the I.n.V.S. is publishing updated results from the latest research conducted in close collaboration with the partners. These results do not support the initial hypothesis of a potential 'Chernobyl effect' in France. The increase in the incidence of thyroid cancer is also reported in most of developed countries. Practices in cancer diagnosis and the increased rate of total thyroidectomy for benign lesion may lead pathologists to unexpectedly discover small thyroid tumors. This fact is likely to explain most of the incidence increase

While indications of modulated intensity radiation therapy (I.M.R.T.) are perfectly defined in head and neck and prostate cancer patients, this technique remains under evaluation for gynecologic tumours. The implementation of conformal three dimensional radiotherapy in the late 1990 has been the first important step for optimisation of treatment of cervix carcinomas, as it permitted a better target coverage with a significant reduction of the bladder dose. However, this technique often leads to an irradiation of a larger volume of rectum in locally advanced stages and could only spare a limited amount of intestine. I.R.M.T. is one of the optimisation methods potentially efficient for a better sparing of digestive tract during irradiation of cervix carcinomas. The aim of this literature review is to provide the arguments supporting this hypothesis, and to define the place of this technique for dose escalation. (authors)

Vivre avec ou par le risque à l’île de Sein ?

Full Text Available L’île de Sein, située au large des côtes finistériennes, fait figure de « territoire du risque » par excellence : cette île basse est confrontée à de fréquentes et violentes tempêtes, la population vit « avec le risque » de submersion depuis des générations tout en voyant la probabilité des aléas catastrophiques augmenter en raison de la carence en aménagement et des conséquences probables du réchauffement climatique. L’image du risque, notamment les photographies de tempête, sert de support à la diffusion d’un sentiment anxiogène justifiant des actions de gestion du risque, mais entretient aussi un sentiment de fascination à l’égard des épisodes tempétueux. Cependant, les îliens portent un regard bien plus critique sur le spectaculaire véhiculé par de telles représentations. Le présent article se penche sur ces rapports entre représentations sociales du risque et iconographie du risque.This article stresses on relationships between hazard’s social representations and iconographies. As an illustration, Sein Island (located near by the Brittany coast, in Finistère. This island is considered as a symbol of natural hazard territory: indeed this low island has been confronted for decades to face significant flood hazard that is nowadays strengthened by the consequences of global warming and a lack of infrastructures. Pictures of flood hazards, and more particularly pictures of storms, are used in order to spread around the fear of natural disasters. This fear justifies the management policies implemented on the island. However islanders criticize pictures which are too spectacular and too distorted. Those gaps between hazard’s representations and iconographies are the main subjects of this article.

A fortran program for elastic scattering of deuterons with an optical model containing tensorial potentials; Programme fortran pour la diffusion elastique de deutons avec un modele optique contenant des termes tensoriels

The optical model has been applied with success to the elastic scattering of particles of spin 0 and 1/2 and to a lesser degree to that of deuterons. For particles of spin l/2, an LS coupling term is ordinarily used; this term is necessary to obtain a polarization; for deuterons, this coupling has been already introduced, but the possible forms of potentials are more numerous (in this case, scalar products of a second rank spin tensor with a tensor of the same rank in space or momentum can occur). These terms which may be necessary are primarily important for the tensor polarization. This problem is of particular interest at Saclay since a beam of polarized deuterons has become available. The FORTRAN program SPM 037 permits the study of the effect of tensorial potentials constructed from the distance of the deuteron from the target and its angular momentum with respect to it. This report should make possible the use and even the modification of the program. It consists of: a description of the problem and of the notation employed, a presentation of the methods adopted, an indication of the necessary data and how they should be introduced, and finally tables of symbols which are in equivalence or common statements: these tables must be considered when making any modification.

Sartre et sa théorie des émotions : une confrontation avec Erving Goffman

Claude Javeau

2010-06-01

Full Text Available L’auteur confronte les positions de Jean-Paul Sartre et Erving Goffman. Dans son ouvrage de 1938, Esquisse d’une théorie des émotions, Jean-Paul Sartre propose une approche phénoménologique prenant doublement ses distances avec la psychanalyse et le béhaviourisme, posant l’émotion comme dégradation spontanée et vécue de la conscience en face du monde, le corps n’étant étrangement dans ce contexte rien d’autre que la croyance vécue de la conscience. L’auteur compare cette position avec la définition goffmanienne de la « situation sociale », qui identifie l’émotion comme une perturbation dans l’ordre normal du déroulement des interactions circonscrites dans la situation. L’interactionnisme symbolique est confronté à l’existentialisme sartrien et à sa position d’une structure magique sous-jacente du monde, en faisant de l’une le miroir de l’autre. Bien que s’inscrivant tous deux dans le courant phénoménologique, Jean-Paul Sartre et Erving Goffman sont ici saisis dans leur stratégie d’évitement des théories psychologiques. En conclusion est posée la question du statut heuristique à conférer au concept de « magique » invoqué par Jean-Paul Sartre.Sartre and his theory of emotions: a confrontation with GoffmanThe author confronts the positions of Jean-Paul Sartre and Erving Goffman. In his Esquisse d’une théorie des émotions (1938, Jean-Paul Sartre proposes a phenomenological approach. Taking his distances both with psychoanalysis and behaviourism, he places emotion as a spontaneous and experienced degradation of the conscience confronted with the world; the body thus becoming strangely nothing other than the experienced belief of consciousness. The author compares this position with Goffman’s definition of the “social situation”. Here, emotion is identified as a disturbance intervening in the normal order of the sequence of events delimited by the situation. Symbolic

Purpose. - To report preliminary results of a prospective study of intensity-modulated radiotherapy (IMRT) for head and neck squamous cell carcinoma (HNC) with bilateral irradiation of the neck. Patients and methods. - At the Alexis Vautrin Cancer Center, 23 patients have been treated with IMRT for HNC since January 2002-August 2003. The first 10 patients with a minimum follow-up of 3 months were analyzed. All tumors were oropharyngeal. There were four females and six males, with a mean age of 50 years (range 39-66). Stages were I-II in eight and III-IV in two. CTV1 was microscopic disease and N0 neck (prescribed dose: 50 Gy) and CTV2 was macroscopic disease and the volume at risk (prescribed dose: 66-70 Gy). PTV were CTV + 5 mm. Patient's immobilization consisted of a five-point head neck shoulder thermoplastic mask. Set-up verifications were done by semi-automatically matching portal images and digitized reconstructed radiographs. IMRT used dynamic multi-leaf collimation. Five patients (group A) received 50 Gy IMRT (two post-operative and three with a brachytherapy boost with a mean dose: 27.5 Gy), and five patients (group B) received 66-70 Gy IMRT (four post-operative). Acute and late normal tissue effects were graded according to the RTOG-EORTC radiation morbidity scoring criteria. Results. - With a median follow-up of 7.4 months (range 3-18.5), no patient died or had loco-regional relapse. The displacements were <4 mm in 98% cases. CTV1 and 2 received 95% of the prescribed dose in 100% of the volume. On average the mean dose to the contralateral parotid was 25.5 Gy for group A vs. 31 Gy for group B (P = 0.09). Mean doses <26 Gy were obtained in three of five patients in group A vs. zero of five patients in group B (P = 0.04). Acute skin toxicities were grade 1 in five patients, grade 2 in four and grade 3 in one. Acute mucositis cases were grade 1 in three patients, grade 2 in five and localized grade 3 in two. At 3 months, 50% of the patients had a grade

Quoique rare le carcinome épidermoïde du scrotum a un mauvais pronostic. Les Carcinomes du scrotum induite et - liées au travail sont moins fréquentes en raison d'une meilleure hygiène, vêtements de protection, et la sensibilisation de la cancérogénicité des huiles industrielles. L’épidémie à l'HPV a induit une augmentation de l'incidence. Le traitement de dépend toujours exérèse locale de la lésion primaire. La radiothérapie a peu de bénéfice thérapeutique dans le traitement d'un carcinome épidermoïde du scrotum. La bléomycine peut être utile comme traitement adjuvant pour les maladies ilio-inguinal généralisée avant la tentative exérèse, même si cela n'a pas encore été prouvé. Entre janvier 2011 au 1er janvier 2013, 7 patients atteints de carcinome épidermoïde ont été pris en charge, Trois patients ont présenté une localisation ganglionnaire. Les sept patients ont eu un traitement chirurgical par exérèse large avec reconstruction, Deux patients ont été adressé pour chimiothérapie.2 patients ont présenté une récidive, dont un est décédé.

The progress of forensic neutron activation analysis/FNAA/ in Japan is described. FNAA began in 1965 and during the past 20 years many cases have been handled; these include determination of toxic materials, comparison examination of physical evidences /e.g.,paints, metal fragments, plastics and inks/ and drug sample differenciation. Neutron activation analysis is applied routinely to the scientific criminal investigation as one of multielement analytical techniques. This paper also discusses these routine works. (author)

Les essais ont ete effectues dans le gaz carbonique purifie, aux pressions de 25 et 60 atmospheres, et a des temperatures allant de 400 a 600, au moyen d'autoclaves speciaux en acier inoxydable, chauffes exterieurement. Leur duree est en general superieure a 1000 heures. Les equations des courbes d'augmentation de poids obtenues sont du type ({delta}p){sup n} = k.t (({delta}p en mg/cm{sup 2} et t en heures), l'exposant n etant voisin de 2, du moins jusqu'a 500 deg. C. En se referant a des resultats precedemment acquis quant a certains de ces materiaux exposes dans le gaz carbonique sous pression atmospherique et sous 15 atmospheres, il apparait que: 1) Pour un materiau determine: - a une pression donnee, l'oxydation augmente avec la temperature, - a une temperature donnee, l'oxydation augmente avec la pression, - dans les memes conditions de temperature et de pression, les resultats obtenus varient peu suivant les deux etats de surface etudies; 2) les alliages Mg-Zr presentent une resistance a l'oxydation amelioree par rapport au magnesium non allie; 3) l'alliage magnox est beaucoup moins avantageux dans le gaz carbonique que dans l'air, par rapport aux autres alliages. D'une facon generale, les courbes d'oxydation tendant vers un palier apres un certain temps d'exposition, la compatibilite de tous les alliages consideres avec le gaz carbonique apparait satisfaisante jusqu'a une temperature voisine de 500 deg. C, dans les conditions operatoires presentement definies; au dessus de 500 deg. C, des differences notables apparaissent entre les divers alliages, mais des phenomenes de sublimation interferent avec ceux d'oxydation, de sorte qu'un classement des divers materiaux ne peut etre base que sur leur resultante.

This study concerns the properties of the excited levels of uranium 236 obtained by interaction of slow neutron with uranium 235. The experiments have been carried out at the Saclay linear electron accelerator by use of the time of flight method. In the first part of this paper, we examine the technical and physical conditions which rule the experiments: compromise between resolution and counting rate, time dispersion due to the slowing down of the neutrons and crystalline binding effects. In a second part the experimental results i.e. total, fission and ternary fission cross sections are given. The third part deals with the analysis of these results: the resonance parameters determination ({tau}{sub n}, {tau}{sub {gamma}}, {tau}{sub f}), the study of their statistical distribution and of their correlations. We tried some classifications of the resonances according to their parameters and compared these classifications to each other and to other results. At least the evidence of a cross section correlation with a range smaller than 100 eV seems to be confirmed.

Effects of grinding on certain crystalline structures; Influence de broyage sur quelques structures cristallines

The effects of grinding on certain crystalline substances (ZnO, ZnS, Sb), have been studied using X-ray diffraction and electron microscopy. The treatments were carried out using a vibrating mill which involves a higher energy than more conventional equipment such as ball-mills. Various methods have been proposed for determining the width of the intrinsic profile ({beta}). In the case of zinc oxide it has been shown possible to differentiate the respective contributions of the fragmentation effects and of lattice deformation effects to the overall effects of the grinding. For the two types of zinc sulfide (blend and Wurtzite) it has been shown that the blend-wurtzite) transition point is very much decreased, and that the rate of transformation of wurtzite into the stable form (blend) at room temperature is considerably increased by the grinding. In the case of antimony, the method of fragmentation shows the existence of an anisotropy which appears to be connected with easily cleavable planes. These observations show that in the case of grinding carried out with sufficient energy, the accumulation of this energy in the matter through the creation of lattice defects can accelerate the reaction rate or bring about physical transformations.

The purpose of the study is to establish if a simple test with 64 Cu is a valuable means of differenciating homozygotes for the ''Wilson's disease gene'' from heterozygous carriers and normal subjects for copper metabolism. A group of 73 subjects were studied. The only parameter which appears to be interesting is the percentage of administrated 64 Cu incorporated into ceruloplasmin at 48h. This test appears to be interesting to predict the disease and to avoid biopsy for determination of hepatic copper concentration [fr

Complexation des acides aminés basiques arginine, histidine et lysine avec l'ADN plasmidique en solution aqueuse : participation à la capture de radicaux sous irradiation X à 1,5 keV

L'environnement chimique de l'ADN en situation biologique est complexe notam-ment en raison de la présence d'histones, protéines nucléaires, associées en quantité approximativement égales à l'ADN pour former la chromatine. Les histones possèdent de nombreux radicaux basiques arginine et lysine chargés positivement et dont la majorité se trouve sur les chaînes émergentes, l'ADN présente quant à lui des charges négatives sur ses groupements phosphates localisés tout au long de la double hélice. Dans cette étude, la complexité de la structure de la chromatine nucléaire est dans un premier temps mimée en solution aqueuse par la formation de complexes entre un ADN plasmidique sonde et les trois acides aminés basiques, Arg, His, Lys, qui, mis à part His, sont protonés au pH physiologique. Ces acides aminés libres en solution sont réputés être des capteurs efficaces de radicaux libres, notamment pour le radical hydroxyle, conférant ainsi un pouvoir protecteur vis-à-vis des effets indirects sur l'ADN en situation d'exposition aux rayonnements ionisants. A concentration fixée, les capacités de capture des acides aminés libres, σ, pour le radical hydroxyle sont typiquement les suivantes σHis ≈σArg > σLys (σLys ≈ 0,1 × σArg). Nous avons mesuré les taux de cassures simple brin par plasmide et par Gray (χ) lors d'expositions de solutions aqueuses de complexes [acide aminé - ADN plasmidique] aux rayons X ultra-mous (1,5 keV). A concentrations égales, les trois acides aminés complexés et présents en large excès ne manifestent pas une capacité de protection de l'ADN proportionnelle à leur capacité de capture libre et en solution ; on trouve en effet des taux de cassures dans l'ordre suivant χHis > χArg > χLys (χLys ≈ 0,01 χArg). Après avoir détaillé le mode opératoire de ces mesures, nous analyserons sur des bases bibliographiques, les modes spécifiques d'interaction des acides aminés basiques avec l'ADN. La sp

LA DIFFERENCIATION « SOLUTION MIRACLE » POUR L’AVENIR DE L’UNION EUROPEENNE?

Directory of Open Access Journals (Sweden)

Bogdana Petrică

2009-03-01

Full Text Available The differentiation has always accompanied the process of integration and it became more evident with the succession of enlargements. This concept originated in the practice of a tighter co-operation between some Member States in certain areas, or in the exceptional derogations given to other Member States which refused participation. Not only these exceptions may become the rule in an enlarged Union, but they appear as being the only solution, sometimes sensitive, and thus spring the need to be well organized. Beginning with the Treaties of Amsterdam and Nice the differentiation is legally enshrined, but it is the works of the Convention for the Drafting of the Constitutional Treaty that advanced the debate on this subject. Finally, the Lisbon Treaty kept most of the provisions of the Constitutional Treaty regarding this subject and for its ratification; it is precisely the concept of differentiation that we shall employ. The Irish “No” demonstrated once more the inevitable obstructions of the unanimity rule, and differentiation might be a solution, while still respecting the diversity of Member States.

Etude de pratiques d'enseignement relatives a la modelisation en sciences et technologies avec des enseignants du secondaire

Science.gov (United States)

Aurousseau, Emmanuelle

Les modeles sont des outils amplement utilises en sciences et technologies (S&T) afin de representer et d’expliquer un phenomene difficilement accessible, voire abstrait. La demarche de modelisation est presentee de maniere explicite dans le programme de formation de l’ecole quebecoise (PFEQ), notamment au 2eme cycle du secondaire (Quebec. Ministere de l'Education du Loisir et du Sport, 2007a). Elle fait ainsi partie des sept demarches auxquelles eleves et enseignants sont censes recourir. Cependant, de nombreuses recherches mettent en avant la difficulte des enseignants a structurer leurs pratiques d’enseignement autour des modeles et de la demarche de modelisation qui sont pourtant reconnus comme indispensables. En effet, les modeles favorisent la conciliation des champs concrets et abstraits entre lesquels le scientifique, meme en herbe, effectue des allers-retours afin de concilier le champ experimental de reference qu’il manipule et observe au champ theorique relie qu’il construit. L’objectif de cette recherche est donc de comprendre comment les modeles et la demarche de modelisation contribuent a faciliter l’articulation du concret et de l’abstrait dans l’enseignement des sciences et des technologies (S&T) au 2eme cycle du secondaire. Pour repondre a cette question, nous avons travaille avec les enseignants dans une perspective collaborative lors de groupes focalises et d’observation en classe. Ces dispositifs ont permis d’examiner les pratiques d’enseignement que quatre enseignants mettent en oeuvre en utilisant des modeles et des demarches de modelisation. L’analyse des pratiques d’enseignement et des ajustements que les enseignants envisagent dans leur pratique nous permet de degager des connaissances a la fois pour la recherche et pour la pratique des enseignants, au regard de l’utilisation des modeles et de la demarche de modelisation en S&T au secondaire.

Other cancers in lung cancer families are overwhelmingly smoking-related cancers

Directory of Open Access Journals (Sweden)

Hongyao Yu

2017-06-01

Full Text Available Familial risks of lung cancer are well-established, but whether lung cancer clusters with other discordant cancers is less certain, particularly beyond smoking-related sites, which may provide evidence on genetic contributions to lung cancer aetiology. We used a novel approach to search for familial associations in the Swedish Family-Cancer Database. This involved assessment of familial relative risk for cancer X in families with increasing numbers of lung cancer patients and, conversely, relative risks for lung cancer in families with increasing numbers of patients with cancers X. However, we lacked information on smoking. The total number of lung cancers in the database was 125 563. We applied stringent statistical criteria and found that seven discordant cancers were associated with lung cancer among family members, and six of these were known to be connected with smoking: oesophageal, upper aerodigestive tract, liver, cervical, kidney and urinary bladder cancers. A further novel finding was that cancer of unknown primary also associated with lung cancer. We also factored in histological evidence and found that anal and connective tissue cancers could be associated with lung cancer for reasons other than smoking. For endometrial and prostate cancers, suggestive negative associations with lung cancer were found. Although we lacked information on smoking it is prudent to conclude that practically all observed discordant associations of lung cancer were with cancers for which smoking is a risk factor.

This article describes the determination and the delineation of the target volumes for head-and-neck cancers treated with intensity-modulated radiotherapy (IMRT). The delineation of the clinical target volumes (CTV) on the computerized tomography scanner (CT scan) requires a rigorous methodology due to the complexity of head-and-neck anatomy. The clinical examination with a sketch of pretreatment tumour extension, the surgical and pathological reports and the adequate images (CT scan, magnetic resonance imaging and fluorodeoxyglucose positron emission tomography) are necessary for the delineation. The target volumes depend on the overall strategy: sequential IMRT or simultaneous integrated boost-IMRT (SIB-IMRT). The concept of selectivity of the potential subclinical disease near the primary tumor and the selection of neck nodal targets are described according to the recommendations and the literature. The planing target volume (PTV), mainly reflecting setup errors (random and systematic), results from a uniform 4-5 mm expansion around the CTV. We propose the successive delineation of: (1) the gross volume tumour (GTV); (2) the 'high risk' CTV1 around the GTV or including the postoperative tumour bed in case of positive margins or nodal extra-capsular spread (65-70 Gy in 30-35 fractions); (3) the CTV2 'intermediate risk' around the CTV1 for SIB-IMRT (59-63 Gy in 30-35 fractions); (4) the 'low-risk' CTV3 (54-56 Gy in 30-35 fractions); (5) the PTVs.

Radioisotopic renal function tests are of assistance to diagnose and follow-up the course of renal insufficiency. The radioisotopic renogram is useful in assessing the response to therapy of child obstructive uropathies and evaluating renal transplant function. The renal scan is helpful, in an emergency service, to differenciate chronic renal insufficiency from acute renal insufficiency. Hg renal uptake test provides informations on physiopathological problems. Among them, the following problems are emphasized: evolution of a nonfunctioning kidney, control of the success of a reparative surgery and of bilateral obstructive uropathies with unilateral symptoms [fr

Full Text Available Des monastères aux funérailles. La construction d’une relation ethnographique avec des chrétiennes de Damas (Syrie. En juillet 2004, j’ai assisté aux funérailles d’un jeune homme de la famille au sein de laquelle je vivais à Damas. À l’époque, l’intense émotion suscitée par cet événement empêcha que je m’y intéresse de plus près. Ce n’est que deux ans plus tard, en juillet 2006, que j’ai décidé d’enquêter sur l’un des aspects majeurs de la cérémonie : les lamentations funèbres féminines. Lors de ce dernier terrain, les femmes de la famille que j’interrogeais, que j’accompagnais aux funérailles et dont j’enregistrais les chants m’assignèrent alors une place tout à fait particulière. Puisque, moi aussi, « je m’habillais en noir et je venais aux funérailles », je ne pouvais plus être considérée comme une étrangère. Dès lors, elles firent de moi la fille d’une de leur sœur émigrée à Paris et mariée avec un Français. Ce statut me fut par ailleurs confirmé lorsqu’elles m’attribuèrent une place dans leurs plaisanteries entre sœurs, tantes et neveux matrilatéraux.Dans cet article, je souhaite engager une double réflexion : sur la position et l’implication de l’ethnologue sur un terrain où l’émotion est au premier plan, ainsi que sur la façon dont être assignée à une place dans la parenté de ses informateurs donne enfin toute liberté d’action à l’ethnologue sur son terrain.From monasteries to funerals.

Although family history of testicular cancer is well-established as a risk factor for testicular cancer, it is unknown whether family history of ovarian cancer is associated with risk of testicular cancer. Using data from the Familial Ovarian Cancer Registry on 2636 families with multiple cases of ovarian cancer, we systematically compared relative frequencies of ovarian cancer among relatives of men with testicular and non-testicular cancers. Thirty-one families with cases of both ovarian and testicular cancer were identified. We observed that, among men with cancer, those with testicular cancer were more likely to have a mother with ovarian cancer than those with non-testicular cancers (OR = 3.32, p = 0.004). Zero paternal grandmothers of men with testicular cancer had ovarian cancer. These observations provide compelling preliminary evidence for a familial association between ovarian and testicular cancers Future studies should be designed to further investigate this association and evaluate X-linkage.

Some reports have indicated that bladder cancer is induced by radiation therapy for cervical cancer. We encountered 6 cases of urothelial cancer (5 cases of bladder cancer and 1 case of ureter cancer) following radiation therapy for cervical cancer. Age at the time of diagnosis of cervical cancer ranged from 38 to 66 years, and the average was 51.2±11.0 (S.D.) years old. Age at the time of diagnosis of urothelial cancer ranged from 53 to 83 years, and the average was 67.5±10.3 years old. The interval between the diagnosis of cervical cancer and urothelial cancer ranged from 3 to 25 years, averaging 16.3 years. It is impossible to evaluate the risk of development of urothelial cancer after radiation therapy based on our data. However, it is important to make an effort to diagnose urothelial cancer at an early stage by educating patients (e.g., advising regular urine tests) after the follow-up period to cervical cancer.

Long non-coding RNAs serve as important regulators in complicated cellular activities, including cell differentiation, proliferation and death. Dysregulation of long non-coding RNAs occurs in the formation and progression of cancers. The family of colon cancer associated transcripts, long non-coding RNAs colon cancer associated transcript-1 and colon cancer associated transcript-2 are known as oncogenes involved in various cancers. Colon cancer associated transcript-1 is a novel lncRNA located in 8q24.2, and colon cancer associated transcript-2 maps to the 8q24.21 region encompassing rs6983267. Colon cancer associated transcripts have close associations with clinical characteristics, such as lymph node metastasis, high TNM stage and short overall survival. Knockdown of them can reverse the malignant phenotypes of cancer cells, including proliferation, migration, invasion and apoptosis. Moreover, they can increase the expression level of c-MYC and oncogenic microRNAs via activating a series of complex mechanisms. In brief, the family of colon cancer associated transcripts may serve as potential biomarkers or therapeutic targets for human cancers. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

Is Hopkins’ “The Windhover” about Christ? A Negative Response, with a Whimsical Postscript Le poème de Hopkins « The Windhover » évoque-t-il le Christ ? Une réponse négative, avec un post-scriptum capricieux

Full Text Available On pense souvent que le célèbre sonnet de Hopkins « The Windhover » (1877, avec sa dédicace « Au Christ notre Seigneur », évoque autant le Christ que le faucon. Mais ce n’est qu’en 1884 que fut ajoutée la dédicace et le texte ne mentionne jamais le Christ. En outre, le poème peut parfaitement être compris comme une description du vol de l’oiseau comme un ravissement – d’abord sans heurts puis luttant contre le vent. Le spectateur admire l’oiseau et le trouve particulièrement glorieux dans sa lutte, le comparant à une charrue qui brille d’un vif éclat alors aux prises avec la terre et à de gris charbons ardents qui rougeoient quand ils se brisent en tombant dans l’âtre. Cette métaphore faite de trois éléments dans le sonnet célèbre donc la gloire de la lutte douloureuse et du triomphe sur l’adversité. Certains lecteurs ajoutent un quatrième élément à la métaphore – le Christ, mais le poème fait pleinement sens sans cet ajout, ce qui montre que le poème n’évoque finalement pas le Christ. Une dernière surprise : ce poème très grave est léger et enjoué dans l’incongruité comique des trois (ou quatre éléments de la métaphore.

Du réel dans l'irréel : la formule hypothétique sans si et avec et

Directory of Open Access Journals (Sweden)

Full Text Available Dans une perspective typologique, le mode conditionnel est très souvent associé à l'irrealis. Il en va de même de la construction hypothétique avec si. Pourtant, dans le domaine de l'imaginaire du présent ou du passé, le verbe principal peut être à l'indicatif quand il s'agit d'indiquer une conséquence infaillible, ce qui suggère que la conséquence peut se voir accorder un statut plus « réel » dans le cadre global de ce qui est toujours un non-fait au moment de l'énonciation. A part le recours à un moyen purement grammatical pour avancer l'idée d'une conséquence inévitable, fort probable ou imminente, il existe la possibilité de coordination de deux propositions (sans si, susceptibles de correspondre à des formules conditionnelles ou temporelles. Il en ressort que l'idée d'une conséquence plus facilement et inévitablement 'concrétisable' peut être promue aussi par un moyen lexical (en l'occurrence, la conjonction et. La possibilité de tels schémas suggère également que l'opposition binaire realis - irrealis n'est pas toujours opératoire : le fait de vouloir présenter certaines conséquences comme plus inévitables que d'autres indique une tendance à évaluer le côté « réel » de la conséquence. L'objectif de la présente étude est d'enquêter sur le modèle de la phrase conditionnelle dépourvue de l'adverbe hypothétique si dans la protase et contenant la conjonction de coordination et dans l'apodose pour évaluer sa part dans la relativisation de l'irréel.

« Comment se comporter avec un roi chrétien » : l’ouvrage perdu d’Abū l-Ḥasan ʿAlī Ibn al-Qaṭṭān et les enjeux du cérémonial almohade

Full Text Available Cet article propose de revenir sur un document aussi exceptionnel que méconnu. Il s’agit du résumé d’un ouvrage (maqāla, aujourd’hui perdu, intitulé « Comment se comporter avec un roi chrétien », et que l’on trouve dans le dictionnaire bio-bibliographique d’Ibn ʿAbd al-Malik. Cette maqāla fut rédigée, par un homme de lettres au service des Almohades, Abū l-Ḥasan ʿAlī Ibn al-Qaṭṭān (m. 1231. C’est la seule source qui ait consigné des indications sur la conduite que devait adopter le souverain lors d’une cérémonie, en présence d’un prince étranger. À ce titre, on y trouve des renseignements essentiels sur le cérémonial almohade ainsi que sur les dilemmes que devaient résoudre le calife : d’un point de vue idéologique, il ne pouvait souffrir aucun autre pouvoir, mais l’impossibilité de mener des opérations d’envergure sur deux fronts à la fois l’amena à composer avec le roi du León. De même, c’est le seul document à avoir fait état d’une divergence de point de vue entre le calife et les intellectuels organiques du système, les Ṭalaba. Ce différend met en lumière des tensions latentes au sommet entre divers serviteurs de l’État, qui n’avaient pas la même forme de légitimité, ni tout à fait les mêmes intérêts.

A case of synchronous triple urogenital cancer, which was comprised of renal cell carcinoma of the left kidney, transitional cell carcinoma of the urinary bladder, and adenocarcinoma of the prostate, is reported. A 72-year-old Japanese male patient was referred to our outpatient clinic with the complaint of asymptomatic hematuria. At that time, his serum of level of PSA was elevated to 20 ng/ml. Cystourethroscopy showed a papillary bladder tumor and coagula through the left urinary orifice. Ultrasonography, computed tomography and magnetic resonance imaging showed a mass lesion measuring about 6 cm by 5 cm in the left kidney. Angiography showed a hypervascular lesion measuring about 6 cm by 5 cm at the same site. Double cancer, consisting of renal cell carcinoma and transitional cell carcinoma of the urinary bladder, was suspected and we performed left total nephroureterectomy, hilar lymphadenectomy, and transurethral rection of the bladder tumor, one month later. At the same time, we performed a biopsy of the prostate. Histological diagnosis was renal cell carcinoma, clear cell carcinoma and transitional cell carcinoma of urinary bladder. Histological diagnosis of the prostate biopsy was moderately differentiated adenocarcinoma. Since this case fulfilled the criteria of Warren and Gates, it was classified as synchronous triple urogenital cancer. A review of the literature revealed 17 authentic cases of triple urogenital cancer, of which 14 and 10 cases were reported as a combination of renal cancer, bladder cancer and prostatic cancer, in the world and in Japan, respectively. Furthermore, he had been exposed to the atomic bomb explosion in Hiroshima in 1945. This carcinogenic precursor may be related to the development of the triple cancer. (author)

It has been long recognized that Thyroid Cancer (TC) envelopes under its umbrella a spectrum of cancers from the relatively indolent well differentiated papillary and follicular cancers to the aggressive and rapidly fatal anaplastic cancers. Medullary cancers fall in between the two extremes. Recently, poor prognostic variants of well-differentiated cancers have been described. There is also a move to define a group of poorly differentiated TC including the insular variants distinguishing them from anaplastic carcinomas. Of the 1168 patients with thyroid nodules seen at the Cancer Institute (WIA), Chennai between 1956 and 1996, 670 cases proved to be malignant either cytologically or histologically. This report is based on the follow-up of these patients which at 10 years was 75%

The present note deals with the study regulations of the sampled type, for 1. order process with simple delay. In order to obtain a good stability in such regulations, together with acceptable performances, it is interesting to use polynomial type correctors acting directly on the sampled error signals. The active elements of these correctors can be shared by all the channels to be controlled. Furthermore, the determination of the correction parameters results from an optimal study of the system. In the second part is described the construction of a multiplexed regulation for diffusion ovens.

Full Text Available Numerical investigations concerning the turbulent flame front propagation in Gasoline Direct Injection (GDI engines were made by implementing a flamelet model in the CFD code Fire. The advantage of this combustion model is the decoupling of the chemistry from the turbulent flow. For this purpose the combustion chamber has to be divided into a burned and an unburned area, which is realized by transporting a scalar field (G-Equation. The reference value defines the present averaged flame position. The complete reaction kinetics is calculated interactively with the CFD code in a one dimensional Representative Interactive Flamelet (RIF code. This combustion model was verified by simulating a 2. 0 l-2 V gasoline engine with homogeneous combustion where a parameter study was conducted to check the flamelet model for plausibility. Finally, the potential of this combustion model was investigated by simulating a hypothetical 2. 0 1-4 V GDI engine. Une investigation numérique relative à la propagation des fronts de flammes turbulents dans les moteurs à essence à injection directe (GDI a été menée en implantant un modèle de flameletdans le code 3D Fire. L'avantage de ce modèle de combustion est de découpler la chimie de l'écoulement turbulent en divisant la chambre de combustion en deux zones : brûlée et imbrûlée, à l'aide d'une équation de transport d'un scalaire (équation de G. Une valeur de référence de ce scalaire définit la position moyenne de la flamme. Une chimie complète est calculée interactivement avec le calcul 3D à l'aide d'un code monodimensionnel RIF (Representative Interactive Flamelet. Le modèle de combustion a été validé sur la simulation d'un moteur 2 litres à 2 soupapes en combustion homogène pour vérifier la représentativité de l'approche flamelet . Puis, le potentiel du modèle de combustion a été étudié en simulant un moteur modèle 2 litres 4 soupapes GDI.

Second cancers following radiotherapy for cervical cancer

Incidence of second primary cancers was evaluated in 7,127 women with invasive cancer of the cervix uteri, diagnosed between 1935 and 1978, and followed up to 38 years (average, 8.9 yr) in Connecticut. Among 5,997 women treated with radiation, 449 developed second primary cancers compared with 313 expected (relative risk . 1.4) on the basis of rates from the Connecticut Tumor Registry. Excess incidence was noticeable 15 years or more after radiotherapy and attributed mostly to cancers of sites in or near the radiation field, especially the bladder, kidneys, rectum, corpus uteri, and ovaries. No excess was found for these sites among the 1,130 nonirradiated women. The ratio of observed to expected cancers for these sites did not vary appreciably by age at irradiation. The data suggested that high-dose pelvic irradiation was associated with increase in cancers of the bladder, kidneys, rectum, ovaries, corpus uteri, and non-Hodgkin's lymphoma but, apparently, not leukemia, Hodgkin's disease, breast cancer, or colon cancer

A reduction in margins defining the forecast target volume thanks to a daily repositioning on intra prostate implants would reduce the doses delivered to the penis bulb, corpora cavernosa penis and a. pudendae internae left and right. An optimization of the I.M.C.R.T. on the same anatomical structures amplifies this earnings. The combination of the two could improve the sexual preservation and be proposed for patients with favourable stage prostate cancer. A study of Phase 2 begins soon. (N.C.)

To study the relative risk of second cancer after radiotherapy, we reviewed 2465 cases of uterine cervical cancer who were treated in our institute from 1962 to 1986 and were followed up for more than 5 years. Among them, 1502 cases were treated by radiotherapy with or without surgery (radiotherapy group), and the remainder were treated by surgery only (surgery only group). We defined second cancer as malignancy that occurred in another organ after an interval of 5 years or more from the end of treatment of the first cancer. The relative risk of second cancer was computed by the person-year method advocated by Schoenberg. Second cancer was observed among 8 cases of the surgery group, whereas 43 cases were observed among the radiotherapy group. The cases were: rectal cancer, 6 cases; bladder cancer, 4 cases. The observed and expected ratio (O/E ratio) was 4.02 in rectal cancer and 7.98 in bladder cancer. This incidence of the both cancers was significantly high in the radiotherapy group. Three of the 6 cases with rectal cancer underwent operation in our institute. The incubation periods between the first and second cancers were from 9 to 21 years. Each case exhibited symptoms of chronic radiation proctitis after radiotherapy for uterine cervical cancer. It is thought necessary to follow up such cases carefully to detect radiation induced cancer. (author)

Cancer and Social Media: A Comparison of Traffic about Breast Cancer, Prostate Cancer, and Other Reproductive Cancers on Twitter and Instagram.

Social media are often heralded as offering cancer campaigns new opportunities to reach the public. However, these campaigns may not be equally successful, depending on the nature of the campaign itself, the type of cancer being addressed, and the social media platform being examined. This study is the first to compare social media activity on Twitter and Instagram across three time periods: #WorldCancerDay in February, the annual month-long campaigns of National Breast Cancer Awareness Month (NBCAM) in October and Movember in November, and during the full year outside of these campaigns. Our results suggest that women's reproductive cancers - especially breast cancer - tend to outperform men's reproductive cancer - especially prostate cancer - across campaigns and social media platforms. Twitter overall generates substantially more activity than Instagram for both cancer campaigns, suggesting Instagram may be an untapped resource. However, the messaging for both campaigns tends to focus on awareness and support rather than on concrete actions and behaviors. We suggest health communication efforts need to focus on effective messaging and building engaged communities for cancer communication across social media platforms.

Despite the progress in cancer treatment over the past years advanced cancer is still an incurable disease. Special attention is pointed toward cancer stem cell (CSC)-targeted therapies, because this minor cell population is responsible for the treatment resistance, metastatic growth and tumor recurrence. The recently described CSC dynamic phenotype and interconversion model of cancer growth hamper even more the possible success of current cancer treatments in advanced cancer stages. Accordingly, CSCs can be generated through dedifferentiation processes from non-CSCs, in particular, when CSC populations are depleted after treatment. In this context, the use of targeted CSC nanomedicines should be considered as a promising tool to increase CSC sensitivity and efficacy of specific anti-CSC therapies.

Cancer in Punjab: evidence from cancer atlas

2015-09-01

Full Text Available Cancer in Punjab has been a news item in the recent past. It was thought that cases in Punjab exceeded the national average and felt that “Punjab the country’s food bowl was in throes of cancer” (1. This presumption was perhaps incorrect. In order to have clarity on the issue, we aimed to review the report of Cancer Atlas in Punjab state for the year 2012-13, recently released by Indian Council of Medical Research (ICMR. The main idea of generating data through Cancer Atlas approach is to assess patterns of cancer in various parts of Punjab state and to estimate cancer incidence at various districts in Punjab. The sources of data collection in the state are all medical colleges, pathology labs, civil hospitals and individual oncologist throughout the state. These data collection sources are considered important as over 80-85% of registered cases of cancer are generally with a microscopic diagnosis (2. Patient data details in the Atlas approach included are Cancer site and morphology of the cancer as per guidelines for collecting information on all malignant cases. The similar approach that adopted in Cancer Atlas in India such as internet approach is used in entering core patient data for Punjab Atlas by standardized procedures.

The kinetic theory of hot-atom reactions is expanded to cover the general system of two reactive species and an inert moderator. From results with a single reactant and moderator, two reactants without moderator, and two reactants with moderator, values of, or ratios of, the reactivity integral I and the average logarithmic energy loss per collision a can be calculated. New results are presented from the reaction of hot tritium produced by the He{sup 3}(n, p)H{sup 3} reaction with the following systems (all contain oxygen scavenger): ethane with helium moderator butane with helium moderator neopentane with helium moderator ethane and butane with and without helium moderator ethane and neopentane with and without helium moderator Values of a and I for the three reactants are calculated from the three types of system and the agreement between the results is discussed in the terms of the accuracy of the model. The results obtained from the different systems agree to within the limits of the experimental error, and this shows that the kinetic theory model can be applied to hot-atom systems with some certainty and that the assumptions made when considering mixtures are reasonable ones. The ratios of the reactivity of the hydrocarbons in mixtures with regard to substitution reactions are not the same as the ratios of the number of hydrogen atoms in the hydrocarbons. The values obtained for these ratios are explained in terms of the values of I and S (the collision cross-section) for the hydrocarbons.

A partir des resultats obtenus au moyen d'un seul corps en reaction et d'un ralentisseur, de deux corps en reaction sans ralentisseur et de deux corps en reaction avec ralentisseur, il est possible de calculer les valeurs ou les rapports de l'integrale de reactivite I, et de la perte d'energie logarithmique

We determined the extent and distribution of cancers in relatives of 379 children newly diagnosed with cancer. Family history was collected from 1,337 first-degree and 3,399 second-degree relatives and incidence compared with national age- and gender-specific rates. Overall, 14 children (3.7%) had a relative with a history of childhood cancer and 26 children (6.9%) had a first-degree relative with a history of cancer, with only one of these having an identifiable familial cancer syndrome. There was a higher than expected incidence of childhood cancer among first-degree relatives (parents and siblings) (standardized incidence ratio (SIR) 1.43; 95% CI 0.54-5.08). There was also a higher than expected incidence of adult cancers among first-degree relatives (SIR 1.45; 95% CI 0.93-2.21), particularly in females (SIR 1.82; 95% CI 1.26-3.39). The increased family cancer history in first-degree females was largely attributable to an effect in mothers (SIR 1.78; 95% CI 1.27-3.33). The gender-specific association was reflected in higher than expected incidence rates of breast cancer in both mothers (SIR 1.92; 95% CI 0.72-6.83) and aunts (SIR 1.64; 95% CI 0.98-2.94). These findings support the hypothesis that previously undetected familial cancer syndromes contribute to childhood cancer.

Maternal lung cancer and testicular cancer risk in the offspring.

Science.gov (United States)

Kaijser, Magnus; Akre, Olof; Cnattingius, Sven; Ekbom, Anders

2003-07-01

It has been hypothesized that smoking during pregnancy could increase the offspring's risk for testicular cancer. This hypothesis is indirectly supported by both ecological studies and studies of cancer aggregations within families. However, results from analytical epidemiological studies are not consistent, possibly due to methodological difficulties. To further study the association between smoking during pregnancy and testicular cancer, we did a population-based cohort study on cancer risk among offspring of women diagnosed with lung cancer. Through the use of the Swedish Cancer Register and the Swedish Second-Generation Register, we identified 8,430 women who developed lung cancer between 1958 and 1997 and delivered sons between 1941 and 1979. Cancer cases among the male offspring were then identified through the Swedish Cancer Register. Standardized incidence ratios were computed, using 95% confidence intervals. We identified 12,592 male offspring of mothers with a subsequent diagnosis of lung cancer, and there were 40 cases of testicular cancer (standardized incidence ratio, 1.90; 95% confidence interval, 1.35-2.58). The association was independent of maternal lung cancer subtype, and the risk of testicular cancer increased stepwise with decreasing time interval between birth and maternal lung cancer diagnosis. Our results support the hypothesis that exposure to cigarette smoking in utero increases the risk of testicular cancer.

How Can We Treat Cancer Disease Not Cancer Cells?

Since molecular biology studies began, researches in biological science have centered on proteins and genes at molecular level of a single cell. Cancer research has also focused on various functions of proteins and genes that distinguish cancer cells from normal cells. Accordingly, most contemporary anticancer drugs have been developed to target abnormal characteristics of cancer cells. Despite the great advances in the development of anticancer drugs, vast majority of patients with advanced cancer have shown grim prognosis and high rate of relapse. To resolve this problem, we must reevaluate our focuses in current cancer research. Cancer should be considered as a systemic disease because cancer cells undergo a complex interaction with various surrounding cells in cancer tissue and spread to whole body through metastasis under the control of the systemic modulation. Human body relies on the cooperative interaction between various tissues and organs, and each organ performs its specialized function through tissue-specific cell networks. Therefore, investigation of the tumor-specific cell networks can provide novel strategy to overcome the limitation of current cancer research. This review presents the limitations of the current cancer research, emphasizing the necessity of studying tissue-specific cell network which could be a new perspective on treating cancer disease, not cancer cells.

Cancer nanomedicine: gold nanoparticle mediated combined cancer therapy

Science.gov (United States)

Yang, C.; Bromma, Kyle; Chithrani, B. D.

2018-02-01

Recent developments in nanotechnology has provided new tools for cancer therapy and diagnosis. Among other nanomaterial systems, gold nanoparticles are being used as radiation dose enhancers and anticancer drug carriers in cancer therapy. Fate of gold nanoparticles within biological tissues can be probed using techniques such as TEM (transmission electron microscopy) and SEM (Scanning Electron Microscopy) due to their high electron density. We have shown for the first time that cancer drug loaded gold nanoparticles can reach the nucleus (or the brain) of cancer cells enhancing the therapeutic effect dramatically. Nucleus of the cancer cells are the most desirable target in cancer therapy. In chemotherapy, smart delivery of highly toxic anticancer drugs through packaging using nanoparticles will reduce the side effects and improve the quality and care of cancer patients. In radiation therapy, use of gold nanoparticles as radiation dose enhancer is very promising due to enhanced localized dose within the cancer tissue. Recent advancement in nanomaterial characterization techniques will facilitate mapping of nanomaterial distribution within biological specimens to correlate the radiobiological effects due to treatment. Hence, gold nanoparticle mediated combined chemoradiation would provide promising tools to achieve personalized and tailored cancer treatments in the near future.

Attitudes and Stereotypes in Lung Cancer versus Breast Cancer.

Directory of Open Access Journals (Sweden)

N Sriram

Full Text Available Societal perceptions may factor into the high rates of nontreatment in patients with lung cancer. To determine whether bias exists toward lung cancer, a study using the Implicit Association Test method of inferring subconscious attitudes and stereotypes from participant reaction times to visual cues was initiated. Participants were primarily recruited from an online survey panel based on US census data. Explicit attitudes regarding lung and breast cancer were derived from participants' ratings (n = 1778 regarding what they thought patients experienced in terms of guilt, shame, and hope (descriptive statements and from participants' opinions regarding whether patients ought to experience such feelings (normative statements. Participants' responses to descriptive and normative statements about lung cancer were compared with responses to statements about breast cancer. Analyses of responses revealed that the participants were more likely to agree with negative descriptive and normative statements about lung cancer than breast cancer (P<0.001. Furthermore, participants had significantly stronger implicit negative associations with lung cancer compared with breast cancer; mean response times in the lung cancer/negative conditions were significantly shorter than in the lung cancer/positive conditions (P<0.001. Patients, caregivers, healthcare providers, and members of the general public had comparable levels of negative implicit attitudes toward lung cancer. These results show that lung cancer was stigmatized by patients, caregivers, healthcare professionals, and the general public. Further research is needed to investigate whether implicit and explicit attitudes and stereotypes affect patient care.

Targeting cancer cells using 3-bromopyruvate for selective cancer treatment

Directory of Open Access Journals (Sweden)

Hussam H Baghdadi

2017-01-01

Full Text Available Cancer treatment deserves more research efforts despite intensive conventional treatment modalities for many types of malignancies. Metastasis and resistance to chemotherapy and radiotherapy receive a lot of global research efforts. The current advances in cancer biology may improve targeting the critical metabolic differences that distinguish cancer cells from normal cells. Cancer cells are highly glycolytic for energy production, exhibit the Warburg effect, establish aggressive acidic microenvironment, maintain cancer stem cells, exhibit resistance to chemotherapy, have low antioxidant systems but different ΔΨm (delta psi, mitochondrial transmembrane potential, express P-glycoprotein for multidrug resistance, upregulate glucose transporters and monocarboxylate transporters and are under high steady-state reactive oxygen species conditions. Normal cells differ in all these aspects. Lactate produced through the Warburg effect helps cancer metastasis. Targeting glycolysis reactions for energy production in cancer cells seems promising in decreasing the proliferation and metastasis of cancer cells. 3-bromopyruvate makes use of cancer biology in treating cancer cells, cancer stem cells and preventing metastasis in human cancer as discussed in this review. Updated advances are analyzed here, which include research analysis of background, experience, readings in the field of cancer biology, oncology and biochemistry.

Cancer stem cells, cancer cell plasticity and radiation therapy.

Science.gov (United States)

Vlashi, Erina; Pajonk, Frank

2015-04-01

Since the first prospective identification of cancer stem cells in solid cancers the cancer stem cell hypothesis has reemerged as a research topic of increasing interest. It postulates that solid cancers are organized hierarchically with a small number of cancer stem cells driving tumor growth, repopulation after injury and metastasis. They give rise to differentiated progeny, which lack these features. The model predicts that for any therapy to provide cure, all cancer stem cells have to be eliminated while the survival of differentiated progeny is less critical. In this review we discuss recent reports challenging the idea of a unidirectional differentiation of cancer cells. These reports provide evidence supporting the idea that non-stem cancer cells exhibit a remarkable degree of plasticity that allows them to re-acquire cancer stem cell traits, especially in the context of radiation therapy. We summarize conditions under which differentiation is reversed and discuss the current knowledge of the underlying mechanisms. Copyright © 2014 Elsevier Ltd. All rights reserved.

Cancer survivorship: a new challenge in comprehensive cancer control.

Science.gov (United States)

Pollack, Lori A; Greer, Greta E; Rowland, Julia H; Miller, Andy; Doneski, Donna; Coughlin, Steven S; Stovall, Ellen; Ulman, Doug

2005-10-01

Cancer survivors are a growing population in the United States because of earlier cancer diagnosis, the aging of society, and more effective risk reduction and treatment. Concerns about the long-term physical, psychosocial, and economic effects of cancer treatment on cancer survivors and their families are increasingly being recognized and addressed by public, private, and non-profit organizations. The purpose of this paper is to discuss how survivorship fits within the framework of comprehensive cancer control. We summarize three national reports on cancer survivorship and highlight how various organizations and programs are striving to address the needs of cancer survivors through public health planning, including the challenges these groups face and the gaps in knowledge and available services. As cancer survivorship issues are being recognized, many organizations have objectives and programs to address concerns of those diagnosed with cancer. However, better coordination and dissemination may decrease overlap and increase the reach of efforts and there is limited evidence for the effectiveness and impact of these efforts.

Metabolic cooperation between cancer and non-cancerous stromal cells is pivotal in cancer progression.

Science.gov (United States)

Lopes-Coelho, Filipa; Gouveia-Fernandes, Sofia; Serpa, Jacinta

2018-02-01

The way cancer cells adapt to microenvironment is crucial for the success of carcinogenesis, and metabolic fitness is essential for a cancer cell to survive and proliferate in a certain organ/tissue. The metabolic remodeling in a tumor niche is endured not only by cancer cells but also by non-cancerous cells that share the same microenvironment. For this reason, tumor cells and stromal cells constitute a complex network of signal and organic compound transfer that supports cellular viability and proliferation. The intensive dual-address cooperation of all components of a tumor sustains disease progression and metastasis. Herein, we will detail the role of cancer-associated fibroblasts, cancer-associated adipocytes, and inflammatory cells, mainly monocytes/macrophages (tumor-associated macrophages), in the remodeling and metabolic adaptation of tumors.

L’obectif était de mettre en relief les particularités du cancer de la thyroïde chez l’enfant et l’adolescent, et d’évaluer nos résultats par rapport à la littérature internationale a travers une série de cas la plus représentatif au Maroc: 22 cas. C'est une étude rétrospective descriptive des patients atteints de cancer différencié de la thyroïde, hospitalisés au service d’ORL et de Chirurgie Cervico-faciale de L’hopital 20 Août de Casablanca-Maroc, sur la période qui s’étend de Janvier 1995 à Mars 2015. Nous avons recueilli les données relatives à 22 cas, qui répondaient à nos critères d’inclusion. L’âge moyen de nos patients était de 14 ans, avec une sex-ratio 3,4, la plupart de nos patients ont consulté pour un nodule thyroïdien, associé dans 22,7% des cas à une adénopathie cervicale, et dans 9,1% à des signes de compression. L’ensemble des patients ont bénéficié d’une thyroïdectomie totale, suivie d’un curage ganglionnaire dans 31,82%. Le diagnostic de cancer thyroïdien a reposé sur l’examen anatomopathologique de la pièce opératoire, qui a objectivé un carcinome papillaire dans 95,4% des cas, et un carcinome vésiculaire dans 4,5%. Le traitement par l’iode radioactif 131 a été réalisé dans 100% des cas. Par la suite tous nos patients ont été mis sous hormonothérapie thyroïdienne. Une surveillance étroite et régulière a permis de détecter des métastases ganglionnaires chez 3 patients, et les métastases à distance chez 4 patients. Le cancer différencié de la thyroïde de l’enfant et l’adolescent est une entité rare mais agressive, son traitement se base sur la chirurgie, associée à l’irathérapie donnant un pronostic excellent.

Concerns remain over the risk of cancer following differentiated thyroid carcinoma and its causes. Iodine-131 ( 131 I) and external irradiation are known to have potential carcinogenic effects. Thyroid carcinoma is a polygenic disease which may be associated with other malignancies. We investigated the incidence of second cancer and its aetiology in a cohort of 875 patients (146 men, 729 women) with differentiated thyroid carcinoma originating from Basse-Normandie, France. Cancer incidence was compared with that of the general population of the Departement du Calvados matched for age, gender and period. The cumulative proportion of second cancer was estimated using the life-table method. Factors that correlated with the risk of second cancer were studied using the Cox model. After a median follow-up of 8 years, 58 second cancers had been observed. Compared with general population incidence rates, there was an overall increased risk of second cancer in women [standardised incidence ratio (SIR)=1.52; P 0.20). Increased risk related to cancers of the genitourinary tract (SIR=3.31; P 131 I was related to the risk. These data confirm that women with differentiated thyroid carcinoma are at risk of developing a second cancer of the genitourinary tract and kidney. Only age and medical history of primary cancer before thyroid carcinoma are risk factors for second cancer. Common environmental or genetic factors as well as long-term carcinogenic effects of primary cancer therapy should be considered. (orig.)

Purpose The risk of breast cancer is high in women treated for a childhood cancer with chest irradiation. We sought to examine variations in risk resulting from irradiation field and radiation dose. Patients and Methods We evaluated cumulative breast cancer risk in 1,230 female childhood cancer survivors treated with chest irradiation who were participants in the CCSS (Childhood Cancer Survivor Study). Results Childhood cancer survivors treated with lower delivered doses of radiation (median, 14 Gy; range, 2 to 20 Gy) to a large volume (whole-lung field) had a high risk of breast cancer (standardized incidence ratio [SIR], 43.6; 95% CI, 27.2 to 70.3), as did survivors treated with high doses of delivered radiation (median, 40 Gy) to the mantle field (SIR, 24.2; 95% CI, 20.7 to 28.3). The cumulative incidence of breast cancer by age 50 years was 30% (95% CI, 25 to 34), with a 35% incidence among Hodgkin lymphoma survivors (95% CI, 29 to 40). Breast cancer–specific mortality at 5 and 10 years was 12% (95% CI, 8 to 18) and 19% (95% CI, 13 to 25), respectively. Conclusion Among women treated for childhood cancer with chest radiation therapy, those treated with whole-lung irradiation have a greater risk of breast cancer than previously recognized, demonstrating the importance of radiation volume. Importantly, mortality associated with breast cancer after childhood cancer is substantial. PMID:24752044

Cast carbide samples, being of a high density and purity, are preferable for research purposes, to samples produced by powder metallurgy methods. Samples of uranium carbide with small additions of zirconium (1 to 5 per cent) were cast, as rods, in an arc furnace. A single phase carbide with interesting qualities was produced. As cast, a dendrite structure is observed, which does not disappear, after a treatment at 1900 deg. C during 110 hours. In comparison with uranium monocarbide the compatibility with stainless steel is much improved. The specific heat (between room temperature and 2500 deg. C) is similar to the specific heat of uranium monocarbide. A study of these mixed carbides, but having a part of the uranium replaced by plutonium is under way. (author) [French] Les echantillons de monocarbures obtenus par coulee sont tres interessants pour les recherches experimentales a cause de leur grande purete, de leur densite tres elevee et de la facilite d'obtention des lingots de forme et dimensions variees. On a prepare et coule dans un four a arc des echantillons de carbures d'uranium avec de faibles additions de zirconium (1 a 5 at. pour cent). On obtient ainsi des carbures monophases presentant de meilleures proprietes que le monocarbure d'uranium. A l'etat brut de coulee on observe une structure dendritique qui n'est pas detruite par un traitement thermique de 110 heures a 1900 deg. C. La compatibilite avec l'acier inoxydable 316 (a 925 deg. C pendant 500 heures) est nettement amelioree par rapport a UC. La chaleur specifique (entre la temperature ordinaire et 2500 deg. C) et la densite sont tres peu differentes de celles du monocarbure d'uranium. Une etude concernant les composes U-Pu-Zr-C est actuellement en cours. (auteur)

the aim of this collaborative project of the Italian Network of Cancer Registries (Airtum; www.registri-tumori.it) was to analyse cancer incidence and mortality trends in Italy with special reference to the period 1998-2005. the study was based on the Airtum database, which collects and checks data from all the Airtum registries. The present study was based on 20 general and 2 specific populationbased cancer registries. Overall, we analysed 818,017 incident cases and 342,444 cancer deaths for the time period 1998-2005. Seventy percent of the analysed population was from the North of Italy, 17% from the Centre, and 13% from the South. A joinpoint analysis was carried out to detect the point in time where the trend changed; trends are described by means of the estimated annual percent change (APC), with appropriate 95% confidence intervals. Crude and standardized incidence and mortality rates were computed for 36 cancer sites, for both sexes, three age-classes (0-49, 50-69 and 70+ years), and three geographic areas (North, Centre, and South of Italy). Specific chapters are devoted to long-term trends (1986-2005), differences among age-groups, and international comparisons. In 1998-2005, cancer mortality for all sites showed a statistically significant decrease among men (APC - 1.7) and women (- 0.8). Mortality significantly decreased in both sexes for stomach cancer, rectum cancer, liver cancer, and Hodgkin lymphoma. Mortality also decreased among men for cancers of the upper aerodigestive tract, oesophagus, lung, prostate, urinary bladder, and leukaemia. Among women mortality decreased for cancers of the colon, bone, breast, and uterus not otherwise specified. An increase in mortality was recorded for lung cancer among women (+1.5) and melanoma among men (+2.6). Incidence for all cancers together (except non-melanoma skin cancers) increased among men (APC +0.3) and remained stable among women. Cancer sites which showed increasing incidence were thyroid and melanoma

Cancer resulting from occupational exposure is now receiving major attention, focusing on identification, regulation, and control of cancer-causing agents. Such cancer can result from exposure to chemicals and ionizing and nonionizing radiation. Extended exposure (often years) and an extended latent period of perhaps decades may intervene before tumor appearance. Although the actual extent of occupational cancer is in debate, estimates have ranged from 4 to 15 per cent of all cancer

Cancer-Related Fatigue in Cancer Survivorship.

Science.gov (United States)

Ebede, Chidinma C; Jang, Yongchang; Escalante, Carmen P

2017-11-01

Cancer-related fatigue (CRF) significantly interferes with usual functioning because of the distressing sense of physical, emotional, and cognitive exhaustion. Assessment of CRF is important and should be performed during the initial cancer diagnosis, throughout cancer treatment, and after treatment using a fatigue scoring scale (mild-severe). The general approach to CRF management applies to cancer survivors at all fatigue levels and includes education, counseling, and other strategies. Nonpharmacologic interventions include psychosocial interventions, exercise, yoga, physically based therapy, dietary management, and sleep therapy. Pharmacologic interventions include psychostimulants. Antidepressants may also benefit when CRF is accompanied by depression. Copyright © 2017 Elsevier Inc. All rights reserved.

Papillary thyroid cancer is often described as the "good cancer" because of its treatability and relatively favorable survival rates. This study sought to characterize the thoughts of papillary thyroid cancer patients as they relate to having the "good cancer." This qualitative study included 31 papillary thyroid cancer patients enrolled in an ongoing randomized trial. Semi-structured interviews were conducted with participants at the preoperative visit and two weeks, six weeks, six months, and one year after thyroidectomy. Grounded theory was used, inductively coding the first 113 interview transcripts with NVivo 11. The concept of thyroid cancer as "good cancer" emerged unprompted from 94% (n = 29) of participants, mostly concentrated around the time of diagnosis. Patients encountered this perception from healthcare providers, Internet research, friends, and preconceived ideas about other cancers. While patients generally appreciated optimism, this perspective also generated negative feelings. It eased the diagnosis of cancer but created confusion when individual experiences varied from expectations. Despite initially feeling reassured, participants described feeling the "good cancer" characterization invalidated their fears of having cancer. Thyroid cancer patients expressed that they did not want to hear that it's "only thyroid cancer" and that it's "no big deal," because "cancer is cancer," and it is significant. Patients with papillary thyroid cancer commonly confront the perception that their malignancy is "good," but the favorable prognosis and treatability of the disease do not comprehensively represent their cancer fight. The "good cancer" perception is at the root of many mixed and confusing emotions. Clinicians emphasize optimistic outcomes, hoping to comfort, but they might inadvertently invalidate the impact thyroid cancer has on patients' lives.

Cancer is one of the major health problems worldwide. In this article, we present for the first time the cancer incidence trends, the distribution and the socioeconomic profile of incident cancer cases in Eastern Morocco over a period of eight years. Retrospective descriptive study of patients diagnosed with cancer at the Hassan II Regional Oncology Center (ROC) since it was created in October 2005 until December 2012. During the study period, the ROC was the only hospital specialized in cancer care in Eastern Morocco. A total of 7872 incident cases of cancer were registered in Eastern Morocco. Among these incident cases 5220 cases were women and 2652 were men, with a female to male ratio of 1.97. The mean age at diagnosis was 58 years for males and 52 for females and 94% of the patients aged over 30 years. For both sexes combined and for all cancer sites, breast cancer was the commonest followed by cervix uteri, colon-rectum, lung, nasopharynx, and stomach cancers. The most common cancer in women was breast cancer, followed respectively by cervix uteri cancer, colon-rectum cancer, ovary cancer, and stomach cancer. In men, the lung cancer ranked first, followed respectively by colon-rectum cancer, nasopharynx cancer, prostate cancer, and stomach cancer. For most cancers, crude incidence rates (CR) have increased significantly. The CR for all cancers combined has increased from 56.6 to 80.3 per 100,000 females and from 32.3 to 42.6 per 100,000 males during the study period. Patients profile analysis showed that 79% of cancer patients were from urban areas, 83% were unemployed and 85% had no health insurance. The distribution of cancers in Eastern Morocco is different from those observed in other regions of Morocco. Unlike most countries, women were much more affected with cancer than men in Eastern Morocco. More importantly, the rates of many cancers are rising. Therefore, our data justify the need to develop effective programs for cancer control and prevention in

Effects of irradiation for cervical cancer on subsequent breast cancer

International Nuclear Information System (INIS)

Harlan, L.C.M.

1985-01-01

Previous research suggests that cervical cancer patients have a lower risk of breast cancer than women in the general population. Possible explanations include opposing risk factors for cervical cancer and breast cancer, the effect of irradiation used to treat cervical cancer, or both. The purpose of this study was to explore the relationship between irradiation for cervical cancer and the subsequent development of breast cancer. There was no statistically significant relationship between radiation to the ovarian area and the risk of breast cancer in this study. However, the results were consistent with a 19% reduction in risk for women irradiated for cervical cancer when compared to nonirradiated women. In a dose-response analysis, there was a nonsignificant trend of decreased risk of breast cancer with increased radiation up to 1800 rad. There was no consistent pattern for higher doses. The trend, although nonsignificant, differed by age. Women <60 years of age at irradiation were generally at a lower risk of breast cancer than nonirradiated women. Women over 59 years were at an increased risk. There are some potentially important findings from this study which might influence medical care. These should be examined in the larger International Radiation Study

He, J

2018-01-23

Cancer is a major chronic disease threatening the people's health in China. We reviewed the latest advances on cancer surveillance, prevention and control in our country, which may provide important clues for future cancer control. We used data from the National Central Cancer Registry, to describe and analyze the latest cancer statistics in China. We summarized updated informations on cancer control policies, conducting network, as well as programs in the country. We provided important suggestions on the future strategies of cancer prevention and control. The overall cancer burden in China has been increasing during the past decades. In 2014, there were about 3 804 000 new cancer cases and 2 296 000 cancer deaths in China. The age-standardized cancer incidence and mortality rates were 190.63/100 000 and 106.98/100 000, respectively. China has formed a comprehensive network on cancer prevention and control. Nationwide population-based cancer surveillance has been built up. The population coverage of cancer surveillance has been expanded, and the data quality has been improved. As the aging population is increasing and unhealthy life styles persist in our country, there will be an unnegligible cancer burden in China. Based on the comprehensive rationale of cancer control and prevention, National Cancer Center of China will perform its duty for future precise cancer control and prevention, based on cancer surveillance statistics.

1989-01-01

It is rare for one human being to be afflicted with more than one cancer. However with further advances in therapeutic regimens, histopathologic observation, diagnostic modalities, and increased curiosity, there are increasing number of case reports of multiple primary cancer. The present study evaluates 25 histologically confirmed cases of multiple primary cancer from 1974 to 1988 at Kosin Medical Center. The most frequent site of the first primary cancer in male was stomach and in female, uterine cervix. The first primary cancer in female occurred in endocrine-related organs (breast, uterus and thyroid) in 63.6 percent. Synchronous cancers are diagnosed simultaneously or within an interval of about six months and synchronous cancers were 16 out of 25 cases. Metachronous cancers are diagnosed at interval of more than six months. There were 9 metachronous cancers and average interval between the first and second primary cancer was 22.8 months. The incidence of multiple primary cancer was 0.11 percent. The average age was 51.9 years at the time of the first primary cancer (53.1 years in male and 50.3 years in female). CT scan was most helpful in early detection of multiple primary cancers facilitating biopsy and surgery. Multiple primary cancers are beyond the medical curiosity. Early diagnosis of the disease and careful follow-up study, based on an awareness of the possibility of second cancers, will substantially increase the survival of these patients

Cancer cachexia

Directory of Open Access Journals (Sweden)

Nada Rotovnik Kozjek

2013-02-01

Full Text Available The present article presents the Slovenian multidisciplinary agreement statement on the definition, staging, clinical classification and multimodal approach to the treatment of cachexia in cancer patients. The consensus was reached during a multidisciplinary plenary session, and is based on the international definition of cancer cachexia adopted in 2011. Cancer cachexia is a multifactorial metabolic syndrome defined by an ongoing loss of skeletal muscle with or without concomitant loss of fat, which cannot be fully reversed by conventional nutritional support and leads to progressive functional impairment. Its pathophysiology is characterized by a negative energy and protein balance due to a variable combination of reduced food intake and metabolic changes. In cancer patients, the cachexia syndrome can develop progressively through various stages – from precachexia to cachexia and finally, to refractory cachexia–represent-ing a continuum of metabolic changes, clini-cal signs and symptoms. Patients can progress from precachexia to cachexia, and reverse from cachexia into precachectic stages, while (as the term itself implies, the condition of refractory or irreversible cachexia has poor therapeutic response. A clinical algorithm for recognition and treatment of cachexia in cancer patients is presented. All cancer patients should be screened for cachexia and precachexia on presentation. Patients who fulfil diagnostic criteria for cancer cachexia should have its clinical stage determined. According to phenotype / clinical stage, a multimodal approach should be adopted in the treatment of all cases of cancer cachexia. A typical multimodal management plan in cachectic patients consists of early dietary intervention, exercise, anti-inflammatory therapy and early cancer-related symptom relief. The cachexia treatment pathway should be adopted as a pathway parallel to conventional cancer treatment. Practical implementation of cancer cachexia

Cancer screening guidelines.

Science.gov (United States)

Zoorob, R; Anderson, R; Cefalu, C; Sidani, M

2001-03-15

Numerous medical organizations have developed cancer screening guidelines. Faced with the broad, and sometimes conflicting, range of recommendations for cancer screening, family physicians must determine the most reasonable and up-to-date method of screening. Major medical organizations have generally achieved consensus on screening guidelines for breast, cervical and colorectal cancer. For breast cancer screening in women ages 50 to 70, clinical breast examination and mammography are generally recommended every one or two years, depending on the medical organization. For cervical cancer screening, most organizations recommend a Papanicolaou test and pelvic examination at least every three years in patients between 20 and 65 years of age. Annual fecal occult blood testing along with flexible sigmoidoscopy at five-year to 10-year intervals is the standard recommendation for colorectal cancer screening in patients older than 50 years. Screening for prostate cancer remains a matter of debate. Some organizations recommend digital rectal examination and a serum prostate-specific antigen test for men older than 50 years, while others do not. In the absence of compelling evidence to indicate a high risk of endometrial cancer, lung cancer, oral cancer and ovarian cancer, almost no medical organizations have developed cancer screening guidelines for these types of cancer.

Breast cancer is the most frequent malignant tumor in women worldwide. In Egypt, it is the most common cancer among women, representing 18.9% of total cancer cases (35.1% in women and 2.2% in men) among the Egypt National Cancer Institute's (NCI) series of 10,556 patients during the year 2001, with an age-adjusted rate of 49.6 per 100,000 people. In this study, the data of all breast cancer patients presented to the surgical department of the South Egypt cancer Institute (SECI) hospital during the period from Janurary 2001 to December 2008 were reviewed .We report the progress of the availability of breast cancer management and evaluation of the quality of care delivered to breast cancer patients. The total number of patients with a breast lump presented to the SECI during the study period was 1,463 patients (32 males and 1431 females); 616 patients from the total number were admitted at the surgical department .There was a decline in advanced cases. Since 2001, facilities for all lines of comprehensive management have been made accessible for all patients. We found that better management could lead to earlier presentation, and better overall outcome in breast cancer patients.The incidence is steadily increasing with a tendency for breast cancer to occur in younger age groups and with advanced stages.

2004-01-01

To screen mutations of the tumor suppressor breast cancer susceptibility gene 1 (BRCA1) within 3 exons among Jordanian breast cancer females. A total of 135 Jordanian breast cancer females were genetically analyzed by denaturing gradient electrophoresis (DGGE) for mutation detection in 3 BRCA1 exons (2, 11 and 20) between 2000-2002 in Al-Basheer Hospital, Amman, Jordan. Of the studied patients 50 had a family history of breast cancer, 28 had a family history of cancer other than breast cancer, and 57 had no family history of any cancer. Five germline mutations were detected among breast cancer females with a family history of breast cancers (one in exon 2 and 4 mutations in exon 11). Another germline mutation (within exon 11) was detected among breast cancer females with family history of cancer other than breast cancer, and no mutation was detected among breast cancer females with no family history of any cancer or among normal control females. Screening mutations within exon 2, exon 11 and exon 20 showed that most screened mutations were within BRCA1 exon 11 among breast cancer Jordanian families with a family history of breast cancer.

Breast Cancer Immunotherapy

Institute of Scientific and Technical Information of China (English)

2004-01-01

Breast cancer is a leading cause of cancer-related deaths in women worldwide. Although tumorectomy,radiotherapy, chemotherapy and hormone replacement therapy have been used for the treatment of breast cancer, there is no effective therapy for patients with invasive and metastatic breast cancer. Immunotherapy may be proved effective in treating patients with advanced breast cancer. Breast cancer immunotherapy includes antibody based immunotherapy, cancer vaccine immunotherapy, adoptive T cell transfer immunotherapy and T cell receptor gene transfer immunotherapy. Antibody based immunotherapy such as the monoclonal antibody against HER-2/neu (trastuzumab) is successfully used in the treatment of breast cancer patients with over-expressed HER-2/neu, however, HER-2/neu is over-expressed only in 25-30% of breast cancer patients. Cancer vaccine immunotherapy is a promising method to treat cancer patients. Cancer vaccines can be used to induce specific anti-tumor immunity in breast cancer patients, but cannot induce objective tumor regression. Adoptive T cell transfer immunotherapy is an effective method in the treatment of melanoma patients. Recent advances in anti-tumor T cell generation ex vivo and limited clinical trial data have made the feasibility of adoptive T cell transfer immunotherapy in the treatment of breast cancer patients. T cell receptor gene transfer can redirect the specificity of T cells. Chimeric receptor, scFv(anti-HER-2/neu)/zeta receptor, was successfully used to redirect cytotoxic T lymphocyte hybridoma cells to obtain anti-HER-2/neu positive tumor cells, suggesting the feasibility of treatment of breast cancer patients with T cell receptor gene transfer immunotherapy. Clinical trials will approve that immunotherapy is an effective method to cure breast cancer disease in the near future.

Breast cancer is a leading cause of cancer-related deaths in women worldwide. Although tumorectomy, radiotherapy, chemotherapy and hormone replacement therapy have been used for the treatment of breast cancer, there is no effective therapy for patients with invasive and metastatic breast cancer. Immunotherapy may be proved effective in treating patients with advanced breast cancer. Breast cancer immunotherapy includes antibody based immunotherapy, cancer vaccine immunotherapy, adoptive T cell transfer immunotherapy and T cell receptor gene transfer immunotherapy. Antibody based immunotherapy such as the monoclonal antibody against HER-2/neu (trastuzumab) is successfully used in the treatment of breast cancer patients with over-expressed HER-2/neu, however, HER-2/neu is over-expressed only in 25-30% of breast cancer patients. Cancer vaccine immunotherapy is a promising method to treat cancer patients. Cancer vaccines can be used to induce specific anti-tumor immunity in breast cancer patients, but cannot induce objective tumor regression. Adoptive T cell transfer immunotherapy is an effective method in the treatment of melanoma patients. Recent advances in anti-tumor T cell generation ex vivo and limited clinical trial data have made the feasibility of adoptive T cell transfer immunotherapy in the treatment of breast cancer patients. T cell receptor gene transfer can redirect the specificity of T cells.

We investigate the association between pre-cancer job dissatisfaction and return-to-work probability 3 years after a cancer diagnosis. We use a Danish data set combining administrative data and a survey to breast and colon cancer survivors. We find that the return-to-work probability has a negative...... correlation with pre-cancer job dissatisfaction with mental demands (where the correlation is driven by the high-educated) and with physical demands and the superior (where the correlation is driven by the low-educated). Educational gradients in the probability of returning to work after cancer...... are not significantly affected by controlling for pre-cancer job dissatisfaction and pre-cancer ability to work....

Lung Cancer

International Nuclear Information System (INIS)

Maghfoor, Irfan; Perry, M.C.

2005-01-01

Lung cancer is the leading cause of cancer-related mortality. Since tobacco smoking is the cause in vast majority of cases, the incidence of lung cancer is expected to rise in those countries with high or rising incidence of tobacco smoking. Even though population at a risk of developing lung cancer are easily identified, mass screening for lung cancer is not supported by currently available evidence. In case of non-small cell lung cancer, a cure may be possible with surgical resection followed by post-operative chemotherapy in those diagnosed at an early stage. A small minority of patients who present with locally advanced disease may also benefit from preoperative chemotherapy and/or radiation therapy to down stage the tumor to render it potentially operable. In a vast majority of patients, however, lung cancer presents at an advanced stage and a cure is not possible with currently available therapeutic strategies. Similarly small cell lung cancer confined to one hemi-thorax may be curable with a combination of chemotherapy and thoracic irradiation followed by prophylactic cranial irradiation, if complete remission is achieved at the primary site. Small cell lung cancer that is spread beyond the confines of one hemi-thorax is however, considered incurable. In this era of molecular targeted therapies, new agents are constantly undergoing pre-clinical and clinical testing with the aim of targeting the molecular pathways thought to involved in etiology and pathogenesis of lung cancer.

Cancer, Stress, and Ironies of Cancer Understanding in South Korea.

Science.gov (United States)

Nelson, Laura C

2017-01-01

Cancer incidence has been rising in South Korea, coincident with industrialization and with increased longevity. This has opened the way to a presentation of cancer as a symptom of prosperity and social advancement. Cancer care for older South Koreans is marketed widely as a way of giving back to the older generation, and is often portrayed as an opportunity to mobilize technological achievement alongside family care work to honor aging parents. Because breast cancer tends to affect a younger cohort, however, breast cancer patients seek more specific explanations for their illness in order to prevent recurrence. Many breast cancer patients identify 'stress' as the cause of their cancer, reflecting endemic stress in the lives of ordinary South Korean women. While this implies a critique of society and, specifically, of gender constructs, the emphasis on interpersonal 'stress' situates cancer causality in family relationships rather than in social, political, or environmental contexts. Cancer management and stress explanations together mute inquiry into causality.

Inflammation has been hypothesized to increase the risk of cancer development as an initiator or promoter, yet no large-scale study of inherited variation across cancer sites has been conducted. We conducted a cross-cancer genomic analysis for the inflammation pathway based on 48 genome-wide association studies within the National Cancer Institute GAME-ON Network across five common cancer sites, with a total of 64 591 cancer patients and 74 467 control patients. Subset-based meta-analysis was used to account for possible disease heterogeneity, and hierarchical modeling was employed to estimate the effect of the subcomponents within the inflammation pathway. The network was visualized by enrichment map. All statistical tests were two-sided. We identified three pleiotropic loci within the inflammation pathway, including one novel locus in Ch12q24 encoding SH2B3 (rs3184504), which reached GWAS significance with a P value of 1.78 x 10(-8), and it showed an association with lung cancer (P = 2.01 x 10(-6)), colorectal cancer (GECCO P = 6.72x10(-6); CORECT P = 3.32x10(-5)), and breast cancer (P = .009). We also identified five key subpathway components with genetic variants that are relevant for the risk of these five cancer sites: inflammatory response for colorectal cancer (P = .006), inflammation related cell cycle gene for lung cancer (P = 1.35x10(-6)), and activation of immune response for ovarian cancer (P = .009). In addition, sequence variations in immune system development played a role in breast cancer etiology (P = .001) and innate immune response was involved in the risk of both colorectal (P = .022) and ovarian cancer (P = .003). Genetic variations in inflammation and its related subpathway components are keys to the development of lung, colorectal, ovary, and breast cancer, including SH2B3, which is associated with lung, colorectal, and breast cancer. © The Author 2015.

Pancreatic cancer is one of the most lethal cancer types worldwide with increasing incidence and mortality rates in the United States. Consequently, it is projected to become the second leading cause of cancer death by 2020. Poor patient outcomes are due to a combination of diagnosis at an advanced stage and a lack of effective treatments. However, a better understanding of the molecular pathways at work in pancreatic cancers may lead to the identification of novel therapeutic targets.

Exploring prostate cancer literacy and family cancer awareness in college students: getting ahead of the curve in cancer education.

Science.gov (United States)

Campbell, Lisa C; McClain, Jasmyne

2013-12-01

Cancer literacy and family cancer experiences have not been widely researched from the perspective of young adults. This study examined health literacy related to prostate cancer and family cancer awareness among a sample of 146 male and female college students. Results supported conventional wisdom that males would be more knowledgeable about the anatomical location of the prostate as compared to females. More notably, across the sample participants had limited knowledge of comprehensive prostate cancer screening but were generally aware of the prostate specific antigen blood test, as well as age and diet as risk factors for prostate cancer. Emerging associations between sexual health history and prostate cancer risk were not widely known by the sample as a whole and perceived availability of prostate health education in college was low. Finally, gender differences in family communication about cancer and racial differences in the number of family members with cancer were observed, which could have implications for perpetuating existing gender and racial gaps in health literacy and cancer awareness. A lifespan approach to cancer education research is suggested to identify ways to promote lifelong learning about cancer, promote prevention behaviors and informed screening in young adulthood, and beyond and better prepare adults to face a family or personal cancer diagnosis should that occur in the future.

Cancer research priorities and gaps in Iran: the influence of cancer burden on cancer research outputs between 1997 and 2014.

As a developing country, Iran is experiencing the increasing burden of cancers, which are currently the third leading cause of mortality in Iran. This study aims to demonstrate that cancer research in Iran concentrates on the cancer research priorities based on the global burden of disease (GBD) reports. Descriptive evaluation of all cancers disability-adjusted life years (DALYs) was performed using GBD data. Also a comprehensive search was conducted using cancer-associated keywords to obtain all cancer-related publications from Iran, indexed in Web of Science. Multiple regression analysis and correlation coefficients (R 2 ) were used to evaluate the possible associations between cancer research publications and GBD. During 1996-2014, the majority of cancer-related publications in Iran focused on breast cancer, leukaemia and stomach cancer, respectively. This study found hypothetical correlations between cancer publications in Iran in line with the burden of cancer as reported by GBD. Particularly, correlations between years lived with disability (YLD) and cancer-related publications were more obvious. This study introduces a new outline in setting cancer research priorities in the region. Copyright © 2016 The Royal Society for Public Health. Published by Elsevier Ltd. All rights reserved.

Skin cancer

International Nuclear Information System (INIS)

Yamada, Michiko

1992-01-01

This chapter reviews the development of skin cancer associated with radiation, focusing on the knowledge of A-bomb radiation-induced skin cancer. Since the discovery of X radiation in 1895, acute and chronic radiation dermatitis has been the first matter of concern. Then, in 1902, skin cancer found among radiological personnel has posed a social problem. In earlier study determining the relationship between skin cancer and A-bomb radiation, there is no increase in the incidence of either skin cancer or precancerous condition during the first 20 years after A-bombing. More recent studies have showed that there is a significant correlation between the incidence of skin cancer and distance from the hypocenter; and the incidence of skin cancer is found to be remarkably increased since 1975 in the group exposed at ≤2,000 m. Excess relative risk is 2.2 at one Gy dose. The incidence of skin cancer is also found to be extremely increased with aging. Relative risk is high in younger A-bomb survivors at the time of exposure. Histologically, basal cell carcinoma is more senstitive to ionizing radiation than squamous cell carcinoma. (N.K.)

Low cancer suspicion following experience of a cancer 'warning sign'.

Science.gov (United States)

Whitaker, Katriina L; Winstanley, Kelly; Macleod, Una; Scott, Suzanne E; Wardle, Jane

2015-11-01

Lower socioeconomic status (SES) is associated with a higher risk of late-stage cancer diagnosis. A number of explanations have been advanced for this, but one which has attracted recent attention is lower patient knowledge of cancer warning signs, leading to delay in help-seeking. However, although there is psychometric evidence of SES differences in knowledge of cancer symptoms, no studies have examined differences in 'cancer suspicion' among people who are actually experiencing a classic warning sign. A 'health survey' was mailed to 9771 adults (⩾50years, no cancer diagnosis) with a symptom list including 10 cancer 'warning signs'. Respondents were asked if they had experienced any of the symptoms in the past 3months, and if so, were asked 'what do you think caused it?' Any mention of cancer was scored as 'cancer suspicion'. SES was indexed by education. Nearly half the respondents (1732/3756) had experienced a 'warning sign', but only 63/1732 (3.6%) mentioned cancer as a possible cause. Lower education was associated with lower likelihood of cancer suspicion: 2.6% of respondents with school-only education versus 7.3% with university education suspected cancer as a possible cause. In multivariable analysis, low education was the only demographic variable independently associated with lower cancer suspicion (odds ratio (OR)=0.34, confidence interval (CI): 0.20-0.59). Levels of cancer suspicion were low overall in this community sample, and even lower in people from less educated backgrounds. This may hinder early symptomatic presentation and contribute to inequalities in stage at diagnosis. Copyright © 2015 The Authors. Published by Elsevier Ltd.. All rights reserved.

Cancer Communication on Social Media: Examining How Cancer Caregivers Use Facebook for Cancer-Related Communication.

Science.gov (United States)

Gage-Bouchard, Elizabeth A; LaValley, Susan; Mollica, Michelle; Beaupin, Lynda Kwon

Americans are increasingly using social media (such as Facebook, YouTube, and Twitter) for health-related communication. Much of the previous research on social media and health communication has focused on Facebook groups related to a specific disease or Facebook pages related to an advocacy organization. Less is known about how people communicate about cancer on personal Facebook pages. In this study, we expand upon previous research by examining how cancer caregivers use personal Facebook pages for cancer-related communication. We examined themes in cancer-related exchanges through a content analysis of 12 months of data from 18 publically available Facebook pages hosted by parents of children with acute lymphoblastic leukemia (15 852 total posts). Six themes emerged: (1) documenting the cancer journey, (2) sharing emotional strain associated with caregiving, (3) promoting awareness and advocacy about pediatric cancer, (4) fundraising, (5) mobilizing support, and (6) expressing gratitude for support. Building upon previous research documenting the increasing use of social media for health-related communication and support, our findings show that personal Facebook pages offer a platform for cancer caregivers to share their cancer-related experiences, promote advocacy and awareness, and mobilize social support. Providers must recognize the importance of social media as a vehicle for support and communication for families of children with cancer. Nurses should educate parents on how to appraise information obtained through Facebook using evidence-based guidelines. Providers can encourage caregivers to use Facebook as a tool for communication, information, and support.

Introduction Une campagne de vaccination contre la méningite A avec le vaccin MenAfriVac a été organisée dans les quatre régions septentrionales du Togo du 28 novembre au 07 décembre 2014. L'approche CTC a été utilisée pour la première fois à une grande échelle pour la campagne de vaccination dans dix districts sanitaires du Togo. L'objectif de cette étude était d'estimer la couverture vaccinale et, de déterminer l'effet de l'utilisation de la Chaîne à Température Contrôlée (CTC) sur ces couvertures vaccinales. Méthodes L'enquête s'est déroulée du 9 au 14 mars 2015, soit environ 3 mois après la fin de la campagne de vaccination dans ces quatre régions. Le sondage en grappe à deux degrés stratifiés selon les régions a été utilisé. Dans 10 districts, le Togo a fait le choix d'utiliser le vaccin MenAfriVac en CTC. Résultats Au total, 2707 ménages ont été enquêtés et 9082 personnes âgées de 1 à 29 ans ont été interviewées. L'âge moyen des personnes enquêtées était de 11,8±7,7 ans et le sex-ratio (H/F) de 1,01. Le nombre moyen de personnes par ménage était de 5,7 et celui des personnes de 1 à 29 ans ciblées par la campagne était de 3,4. Sur les 9082 personnes enquêtées, 8889 (98%) étaient vaccinées. En analyse multivariée, les facteurs associés à la couverture vaccinale avec le MenAfrivac étaient la résidence dans la zone au moment de la campagne (aOR = 4,52 ; 95%IC = [4.07 - 4.97]) et le fait d'être informé de la campagne avant son démarrage (aOR=2,42 ; 95%IC = [2.05 - 2.80]). Par contre, la couverture vaccinale n'était pas différente selon la zone ayant utilisé l'approche CTC ou non (aOR=0,09 ; 95%IC = [-0,27-0,45]). Deux cent sept personnes interrogées (2,3%) ont déclaré avoir eu une Manifestation Adverse Post Immunisation (MAPI) après l'administration du vaccin. Il s'agissait surtout de MAPI mineures à type de fièvre, d'abcès et de gonflement au point d'injection. Conclusion Les r

Improved cancer screening and treatment advances have led to higher cancer survival rates in the United States. However, racial disparities in breast cancer survival persist for African American women who experience lower survival rates than white women. These disparities suggest that unmet needs related to survivorship still exist. This study focuses on the challenges that both African American cancer survivors and caregivers face across the cancer continuum. Five African American focus groups examined cancer survivor and caregiver support needs. Focus groups were recorded, transcribed, and uploaded into Atlas.ti. Thematic content analysis was applied to the text during the coding process. Themes were identified and emphasized based on the research team's integrated and unified final codes. Forty-one African Americans participated in five focus groups: 22 cancer survivors and 19 caregivers. Participants discussed five themes: (1) a culture that discourages the discussion of cancer; (2) lack of support services for African American cancer survivors; (3) lack of support services for cancer caregivers; (4) need for culturally appropriate cancer resources, including resources targeted at African American women; and (5) aspects that were helpful to cancer survivors and caregivers, including connecting with other survivors and caregivers, and having strong social support networks. We gained new insight into the unmet support needs for survivors and caregivers, especially when coping with the cancer experience continuum. While some cancer and caregiver support services exist, our study reveals a great need for services that incorporate the cultural differences that exist across races.

Familial aggregation of testicular cancer has been reported consistently, but it is less clear if there is any association between risk of testicular cancer and other cancers in the family. We conducted a population based case-control study to examine the relationship between risk of testicular cancer and 22 different cancers in first-degree relatives. We included 3297 cases of testicular cancer notified to the Danish Cancer Registry between 1991 and 2003. 6594 matched controls were selected from the Danish Civil Registration System, which also provided the identity of 40,104 first-degree relatives of case and controls. Familial cancer was identified by linkage to the Danish Cancer Registry, and we used conditional logistic regression to analyse whether cancer among first-degree relatives was associated with higher risk of testicular cancer. Rate ratio (RR) for testicular cancer was 4.63 (95% CI: 2.41–8.87) when a father, 8.30(95% CI: 3.81–18.10) when a brother and 5.23 (95% CI: 1.35–20.26) when a son had testicular cancer compared with no familial testicular cancer. Results were similar when analyses were stratified by histologic subtypes of testicular cancer. Familial Non-Hodgkin lymphoma and oesophageal cancer were associated with testicular cancer; however these may be chance findings. The familial aggregation of testicular and possibly other cancers may be explained by shared genes and/or shared environmental factors, but the mutual importance of each of these is difficult to determine.

Prostate cancer is the third leading cause of cancer-related death among men, killing an estimated 27,000 men each year in the United States. Men with advanced prostate cancer often become resistant to conventional therapies. Many researchers speculate that the emergence of resistance is due to the presence of cancer stem cells, which are believed to be a small subpopulation

The purpose of this study was to compare differences in health-related quality of life (HRQOL) between African-American female breast cancer survivors, African-American female survivors of other cancers, and African-American women with no history of cancer. Using data from the 2010 National Health Interview Survey (NHIS), the HRQOL of African-American women aged 35 years or older was compared by cancer status. Physical and mental health items from the Patient-Reported Outcomes Measurement Information System (PROMIS) global health scale were used to assess differences in HRQOL. For summary physical and mental health measures, no significant differences were found between breast cancer survivors and women with no history of cancer; survivors of other cancers reported poorer physical and mental health than did women with no history of cancer. Similar differences were found at the item level. When we examined the two African-American female cancer survivor groups, we found that cancer survivors whose cancer was being treated reported substantially poorer physical health and mental health than did those whose cancer was not being treated. Survivors who had private insurance and were cancer free reported better physical and mental health than did those who did not have private insurance and those who were not cancer free. Breast cancer survivors reported slightly better physical and mental health than did survivors of other cancers. Our findings highlight the need for public health agencies to adopt practices to improve the mental and physical health of African-American female survivors of cancer.

Northeast Regional Cancer Institute's Cancer Surveillance and Risk Factor Program

Energy Technology Data Exchange (ETDEWEB)

Lesko, Samuel M.

2007-07-31

OBJECTIVES The Northeast Regional Cancer Institute is conducting a program of ongoing epidemiologic research to address cancer disparities in northeast Pennsylvania. Of particular concern are disparities in the incidence of, stage at diagnosis, and mortality from colorectal cancer. In northeast Pennsylvania, age-adjusted incidence and mortality rates for colorectal cancer are higher, and a significantly smaller proportion of new colorectal cancer cases are diagnosed with local stage disease than is observed in comparable national data. Further, estimates of the prevalence of colorectal cancer screening in northeast Pennsylvania are lower than the US average. The Northeast Regional Cancer Institute’s research program supports surveillance of common cancers, investigations of cancer risk factors and screening behaviors, and the development of resources to further cancer research in this community. This project has the following specific objectives: I. To conduct cancer surveillance in northeast Pennsylvania. a. To monitor incidence and mortality for all common cancers, and colorectal cancer, in particular, and b. To document changes in the stage at diagnosis of colorectal cancer in this high-risk, underserved community. II. To conduct a population-based study of cancer risk factors and screening behavior in a six county region of northeast Pennsylvania. a. To monitor and document changes in colorectal cancer screening rates, and b. To document the prevalence of cancer risk factors (especially factors that increase the risk of colorectal cancer) and to identify those risk factors that are unusually common in this community. APPROACH Cancer surveillance was conducted using data from the Northeast Regional Cancer Institute’s population-based Regional Cancer Registry, the Pennsylvania Cancer Registry, and NCI’s SEER program. For common cancers, incidence and mortality were examined by county within the region and compared to data for similar populations in the US

Mechanisms of Cancer Cell Dormancy--Another Hallmark of Cancer?

Science.gov (United States)

Yeh, Albert C; Ramaswamy, Sridhar

2015-12-01

Disease relapse in cancer patients many years after clinical remission, often referred to as cancer dormancy, is well documented but remains an incompletely understood phenomenon on the biologic level. Recent reviews have summarized potential models that can explain this phenomenon, including angiogenic, immunologic, and cellular dormancy. We focus on mechanisms of cellular dormancy as newer biologic insights have enabled better understanding of this process. We provide a historical context, synthesize current advances in the field, and propose a mechanistic framework that treats cancer cell dormancy as a dynamic cell state conferring a fitness advantage to an evolving malignancy under stress. Cellular dormancy appears to be an active process that can be toggled through a variety of signaling mechanisms that ultimately downregulate the RAS/MAPK and PI(3)K/AKT pathways, an ability that is preserved even in cancers that constitutively depend on these pathways for their growth and survival. Just as unbridled proliferation is a key hallmark of cancer, the ability of cancer cells to become quiescent may be critical to evolving malignancies, with implications for understanding cancer initiation, progression, and treatment resistance. ©2015 American Association for Cancer Research.

2015-11-01

The aim was to describe male cancer survivors' barriers towards participation in cancer rehabilitation as a means to guiding future targeted men's cancer rehabilitation. Symbolic Interactionism along with the interpretive descriptive methodology guided the study of 35 male cancer survivors representing seven cancer types. Data were generated through a 5-month fieldwork study comprising participant observations, semi-structured individual interviews and informal conversations. The analyses revealed two overarching findings shedding light on male cancer survivors' barriers to rehabilitation: 'Fear of losing control' and 'Striving for normality'. While 'Fear of losing control' signified what the men believed rehabilitation would invoke: 'Reduced manliness', 'Sympathy and dependency' and 'Confrontation with death', 'Striving for normality' was based on what the men believed rehabilitation would hinder: 'Autonomy and purpose', 'Solidarity and fellowship' and 'Forget and move on'. This study of male cancer survivors' and cancer rehabilitation documents how masculine ideals may constitute barriers for participation in rehabilitation and provides insights about why men are underrepresented in rehabilitation. The findings can guide practice to develop research-based rehabilitation approaches focused on preserving control and normality. Further empirical evidence is needed to: (1) explore the conduct of health professionals' towards male cancer patients and (2) address gender inequalities in cancer rehabilitation. © 2015 John Wiley & Sons Ltd.

Evolutionary Origins of Cancer Driver Genes and Implications for Cancer Prognosis.

The cancer atavistic theory suggests that carcinogenesis is a reverse evolution process. It is thus of great interest to explore the evolutionary origins of cancer driver genes and the relevant mechanisms underlying the carcinogenesis. Moreover, the evolutionary features of cancer driver genes could be helpful in selecting cancer biomarkers from high-throughput data. In this study, through analyzing the cancer endogenous molecular networks, we revealed that the subnetwork originating from eukaryota could control the unlimited proliferation of cancer cells, and the subnetwork originating from eumetazoa could recapitulate the other hallmarks of cancer. In addition, investigations based on multiple datasets revealed that cancer driver genes were enriched in genes originating from eukaryota, opisthokonta, and eumetazoa. These results have important implications for enhancing the robustness of cancer prognosis models through selecting the gene signatures by the gene age information.

Two nationwide observational surveys were carried out in France in 2005 and 2008 with the aim of assessing the impact on attitudes towards cancer screening of a positive history of cancer among a person's close circle of acquaintances (relatives, friends or colleagues). In 2005, 67% (993/1482) of people interviewed reported having someone in their close circle of acquaintances affected by cancer and in 2008, the rate was 80% (1158/1454). In 2008, having someone within a person's close circle of acquaintances affected by cancer did not increase the rate of screening for breast cancer (already high at >80%). However, it did increase the rate of screening for colorectal cancer [odds ratio (OR)=2.3; 95% confidence interval (CI)=1.6-3.3] and prostate cancer (OR=2.2; 95% CI=1.4-3.5). Knowing someone affected by cancer within the close circle of acquaintances clearly increases awareness, and thus could be an incentive for undergoing cancer screening. With regard to cancer types, such as prostate cancer, for which there is no national programme or media communication, this awareness might be the main source of information and motivation. The impact of awareness on screening behaviour seems to be greatest for the same cancer location as that in the affected acquaintance, as opposed to cancers at other sites. Increased awareness as observed in our survey, which may be attributable to less social stigma associated with a diagnosis of cancer, might increase the rate of screening attendance in the general population.

The early cancer studies on immigrants, which started to appear some 50 years ago, showed that the incidence in cancers changes to the level of the new host country in one or two generations. These findings were fundamental to the understanding of the environmental etiology of human cancer. Many immigrant groups originate from countries with no cancer registration, and, hence, the immigrant studies may provide estimates on the indigenous cancer rates. The Swedish Family-Cancer Database has been an important source of data for immigrant studies on various diseases. The Database covers the Swedish population of the past 100 years, and it records the country of birth for each subject. A total of 1.79 million individuals were foreign born, Finns and other Scandinavians being the largest immigrant groups. Over the course of years, some 30 publications have appeared relating to cancer in immigrants. In the present article, we will review more recent immigrant studies, mainly among Swedish immigrants, on all cancers and emphasize the differences between ethnic groups. In the second part, we discuss the problem of reliable registration of cancer and compare cancer incidence among non-European immigrants with cancer incidence in countries of origin, as these have now active cancer registries. We discuss the experiences in cancer registration in Morocco and Egypt. We show the usefulness and limitations in predicting cancer incidence in the countries of origin. © The Author 2014.

A family history of pancreatic cancer has consistently been associated with increased risk of pancreatic cancer. However, uncertainty remains about the strength of this association. Results from previous studies suggest a family history of select cancers (i.e. ovarian, breast, and colorectal) could also be associated, although not as strongly, with increased risk of pancreatic cancer. We examined the association between a family history of five types of cancer (pancreas, prostate, ovarian, breast, and colorectal) and risk of pancreatic cancer using data from a collaborative nested case-control study conducted by the Pancreatic Cancer Cohort Consortium. Cases and controls were from cohort studies from the United States, Europe, and China, and a case-control study from the Mayo Clinic. Analyses of family history of pancreatic cancer included 1,183 cases and 1,205 controls. A family history of pancreatic cancer in a parent, sibling, or child was associated with increased risk of pancreatic cancer (multivariate-adjusted OR = 1.76, 95% CI 1.19–2.61). A family history of prostate cancer was also associated with increased risk (OR = 1.45, 95% CI 1.12–1.89). There were no statistically significant associations with a family history of ovarian cancer (OR = 0.82, 95% CI 0.52–1.31), breast cancer (OR = 1.21, 95% CI 0.97–1.51), or colorectal cancer (OR = 1.17, 95% CI 0.93–1.47). Our results confirm a moderate sized association between a family history of pancreatic cancer and risk of pancreatic cancer and also provide evidence for an association with a family history of prostate cancer worth further study.

Managing work and cancer treatment: Experiences among survivors of hematological cancer.

Science.gov (United States)

Thomson, Maria D; Siminoff, Laura A

2018-04-16

The current study was performed to characterize the employment status of survivors of hematological cancer who have an informal caregiver from the time of diagnosis through the first 6 months of treatment. Using a mixed methods approach, semistructured interviews with survivors of hematological cancer were conducted within 6 months of the initiation of cancer treatment. Interviews assessed cancer treatment status, barriers and facilitators to employment, financial and insurance status, and relationship with the primary caregiver. These results are part of a longitudinal study of cancer survivors and informal caregivers. A total of 171 patients were enrolled. Within 6 months of beginning cancer treatments, approximately 35% were no longer employed. Reasons to remain employed included financial need, employee benefits, and a sense of purpose and normalcy. Employer accommodations and supportive colleagues facilitated continued employment. Logistic regression analysis demonstrated that having a higher household income, a desire to work, nonphysical job tasks, and congruent survivor-caregiver communication were associated with greater odds of remaining employed. Within 6 months of initiating cancer treatment, the majority of survivors of hematological cancer had maintained employment. Because of the limitations imposed by the physical stress of cancer treatments, as well as the need to maintain employment to continue receiving employee benefits to cover such treatments, survivors of hematological cancer likely would benefit from employment accommodations that are sensitive to their unique needs.

Targeting Stromal-Cancer Cell Crosstalk Networks in Ovarian Cancer Treatment

Directory of Open Access Journals (Sweden)

Tsz-Lun Yeung

2016-01-01

Full Text Available Ovarian cancer is a histologically, clinically, and molecularly diverse disease with a five-year survival rate of less than 30%. It has been estimated that approximately 21,980 new cases of epithelial ovarian cancer will be diagnosed and 14,270 deaths will occur in the United States in 2015, making it the most lethal gynecologic malignancy. Ovarian tumor tissue is composed of cancer cells and a collection of different stromal cells. There is increasing evidence that demonstrates that stromal involvement is important in ovarian cancer pathogenesis. Therefore, stroma-specific signaling pathways, stroma-derived factors, and genetic changes in the tumor stroma present unique opportunities for improving the diagnosis and treatment of ovarian cancer. Cancer-associated fibroblasts (CAFs are one of the major components of the tumor stroma that have demonstrated supportive roles in tumor progression. In this review, we highlight various types of signaling crosstalk between ovarian cancer cells and stromal cells, particularly with CAFs. In addition to evaluating the importance of signaling crosstalk in ovarian cancer progression, we discuss approaches that can be used to target tumor-promoting signaling crosstalk and how these approaches can be translated into potential ovarian cancer treatment.

[Sexy cancer--sexuality for cancer patients].

Science.gov (United States)

Peleg-Nesher, Sharon; Yachini, Brurya; Inbar, Moshe

2009-09-01

Sexuality is a basic need for every human being as long as he or she is alive, irrespective of age or health status. Approximately 23,500 individuals are diagnosed with cancer each year in Israel and join the 120,000 cancer patients currently living in Israel. The results of cancer treatments are traditionally assessed and based on the outcome regarding mortality versus survival. An equally important aspect to be addressed in this assessment must relate to quality of life. One of the more painful insults to the quality of life of cancer patients relates to the deleterious effects on sexuality. This article aims to present physicians with the spectrum of sexuality-related issues which are encountered by cancer patients and their partners, starting from the moment of diagnosis, throughout the various stages of treatment and to provide basic knowledge. Many individuals contracting cancer have difficulty dealing with the issue of sexuality. They are typically embarrassed and feel uneasy when asking health care providers about such a non-life threatening issue. Partners similarly feel both shame and guilt. In many cases sexuality, intimacy and emotional attachment are important aspects and may be essential for survival. Addressing these issues during treatment can provide patients with a sense of security, avoiding embarrassment and further exacerbation of such problems. Unfortunately, little has been done to develop an optimal interventional program, although standard sexual treatments have often been applied. Prospective clinical research and outcomes are missing. The physician can use the well-known PLISSIT model (1978): to provide sexuality involvement on different levels. The very new BETTER model (2004) can help emphasize that cancer treatment and the disease have an influence on intimacy and sexuality.

Contraintes de taille dans les mots composés : quand la phonologie entre en concurrence avec les contraintes morphologiques

Full Text Available Cette communication porte sur les contraintes phonologiques qui pèsent sur la formation des mots construits dans le cadre théorique de la morphologie lexématique (Anderson 1992, Aronoff 1994, Fradin 2003. En étudiant les données du français, les travaux de Lignon (à paraître, Plénat (2009 & Roché (2003 ont montré que des contraintes de taille étaient à l’œuvre dans plusieurs constructions morphologiques. L’objectif de cet article est d’étudier cette hypothèse sur les mots composés Verbe-Nom du français (Villoing 2009. L’analyse quantitative des données du corpus montre clairement que les verbes des mots composés VN du français sont soumis à des contraintes de taille et doivent répondre au format d’un monosyllabe. La contrainte pèse moins lourdement sur les noms qui parviennent à s’imposer plus facilement que les verbes avec une taille supérieure. Cependant, la majorité des mots composés VN tend à ne pas dépasser trois syllabes (leur format optimal étant de deux ou trois syllabes, révélant ainsi l'influence des contraintes de taille sur le mot composé lui-même. La mise au jour de ces contraintes permet d'expliquer l’absence de certains verbes dans le corpus de composés VN, répondant pourtant bien aux propriétés sémantiques attendues : les verbes construits par affixation (absence de suffixés en -iser, -ifier; très rares cas de préfixés, les verbes du 2ème groupe, les verbes de taille supérieure à trois syllabes. En outre, cet article met au jour un cas de concurrence entre contrainte morphologique et contrainte phonologique au sein d'une construction morphologique, et montre comment la première l'emporte sur la dernière, bien que la contrainte phonologique contraigne fortement le choix du verbe et du nom de base. Il donne également à voir comment la contrainte phonologique parvient néanmoins à influencer le choix de bases sémantiquement peu conformes aux attentes de la règle.

The largest Chamorro population outside of Guam and the Mariana Islands reside in California. Cancer health disparities disproportionally affect Pacific Islander communities, including the Chamorro, and breast cancer is the most common cancer affecting women. To address health concerns such as cancer, Pacific Islander women frequently utilize storytelling to initiate conversations about health and to address sensitive topics such as breast health and cancer. One form of storytelling used in San Diego is a play that conveys the message of breast cancer screening to the community in a culturally and linguistically appropriate way. This play, Nan Nena’s Mammogram, tells the story of an older woman in the community who learns about breast cancer screening from her young niece. The story builds upon the underpinnings of Chamorro culture - family, community, support, and humor - to portray discussing breast health, getting support for breast screening, and visiting the doctor. The story of Nan Nena’s Mammogram reflects the willingness of a few pioneering Chamorro women to use their personal experiences of cancer survivorship to promote screening for others. Through the support of a Chamorro community-based organization, these Chamorro breast cancer survivors have used the success of Nan Nena’s Mammogram to expand their education activities and to form a new cancer survivor organization for Chamorro women in San Diego.

Different site specificity of second primary cancer following treatment for early stage squamous cell carcinoma of the head and neck was found in the analysis of post-treatment long-term follow up cases. The highest risk of second primary cancer was observed in the oro-hypo-pharynx cancer groups, and the lowest risks were observed in the epi-pharynx cancer and maxillary sinus cancer groups. Squamous cell carcinoma in the irradiated head and neck region with long latency periods could be included in the radiation induced cancer from comparison with post-irradiation cases for malignant lymphoma, benign diseases as well as breast cancers.

Thyroid Cancer Presenting with Concomitant Metastatic Breast Cancer in the Thyroid

Directory of Open Access Journals (Sweden)

Chung-Chen Wang

2014-12-01

Full Text Available The thyroid is an unusual site to find cancer metastasis. When it does occur, such cancer spread is often manifested in multiple metastases and generally suggests a poor prognosis. We presented here a 49-year-old woman recently diagnosed with thyroid cancer, who had been treated for stage IIA breast cancer 8 years ago. After radical right thyroidectomy and left subtotal thyroidectomy, her pathological report showed papillary thyroid carcinoma, right thyroid, with concomitant metastatic breast carcinoma. This is the first case of which we are aware involving coexisting thyroid cancer and metastatic breast cancer in the ipsilateral lobe. Moreover, the circumstances of this case show a very unique clinical course compared with previous studies. Given the unusual circumstances of our case, we further discuss the relationship between thyroid cancer and breast cancer.

Cancer3D: understanding cancer mutations through protein structures.

Porta-Pardo, Eduard; Hrabe, Thomas; Godzik, Adam

2015-01-01

The new era of cancer genomics is providing us with extensive knowledge of mutations and other alterations in cancer. The Cancer3D database at http://www.cancer3d.org gives an open and user-friendly way to analyze cancer missense mutations in the context of structures of proteins in which they are found. The database also helps users analyze the distribution patterns of the mutations as well as their relationship to changes in drug activity through two algorithms: e-Driver and e-Drug. These algorithms use knowledge of modular structure of genes and proteins to separately study each region. This approach allows users to find novel candidate driver regions or drug biomarkers that cannot be found when similar analyses are done on the whole-gene level. The Cancer3D database provides access to the results of such analyses based on data from The Cancer Genome Atlas (TCGA) and the Cancer Cell Line Encyclopedia (CCLE). In addition, it displays mutations from over 14,700 proteins mapped to more than 24,300 structures from PDB. This helps users visualize the distribution of mutations and identify novel three-dimensional patterns in their distribution. © The Author(s) 2014.

This paper explained the current state of radiotherapy for bladder cancer and kidney cancer, and discussed the role of radiotherapy in curative treatment and the future development. In the diagnosis and treatment of bladder cancer, it is important to judge the existence of pathological muscular layer invasion based on transurethral resection of bladder tumor (TUR-BT). In surgical results in Japan, the U.S., and Switzerland, 5-year survival rate is about 60 to 70%. Standard treatment for bladder cancer with muscle layer invasion had been surgery, and radiotherapy had been applied to the cases without resistance to surgery. Three combined therapy with TUR-BT and simultaneous chemoradiotherapy is the current standard bladder conserving therapy. The 5-year survival rate is approximately 60%, which is superior to the treatment with irradiation alone. Radiotherapy for kidney cancer is most often used as perioperative treatment for locally advanced cancer or as symptomatic treatment for metastatic lesions. However, due to recent improvement in radiotherapy technology, correspondence to respiratory movement and high dose administration associated with improvement in dose concentration have been realized, and stereotactic irradiation using a high single dose for inoperable disease cases or surgery refusal disease cases has come to be clinically applied.

Oral cancer.

Gerson, S J

In the U.S. oral cancer accounts for 2.1% of all cancers and 1% of cancer deaths. Two to three times as many males as females are affected. Blacks have more intra-oral cancer than whites, and their incidence and mortality rates have increased in recent years. The etiologic process very likely involves several factors. The major etiologic agents are tobacco (all types) and alcoholic beverages. Herpes simplex virus, human papilloma virus, and Candida have been implicated. Host factors include poor state of dentition, nutritional aberrations, cirrhosis of liver, lichen planus, and immunologic impairmant. Cellular changes include amplification of some oncogenes, alterations in antigen expression, production of gamma-glutamyl transpeptidase, and disturbance of keratin and involucrin production. Experimentally, cancer is readily produced on the hamster cheek pouch and rat oral mucosa. Unlike oral cancer in humans, most experimental lesions are exophytic, and they rarely metastasize.

Estimates of the number of childhood cancers with a genetic basis range from 5-8.5% found in germline samples to 29% based on clinical criteria. Family history-taking practice is a fundamental first step in detecting at risk individuals and families. This study focused on Li-Fraumeni Syndrome (LFS), a highly penetrant cancer syndrome. Reported family history in a cohort of 648 of cancer survivor cohort (CCS) was examined. Eligible CCS were: (i) aged up to 14 years at diagnosis; (ii) more than 5 years postdiagnosis; (iii) treated for a childhood cancer at the study hospitals in NSW, Australia; (iv) in remission for more than 3 years. CCS completed self-administered questionnaires. Medical records confirmed diagnosis and treatment-related information. Our findings reveal an increased cancer risk among sibling and relatives of CCS. 91% of siblings diagnosed with cancer were diagnosed under the age of 40 and about 30% diagnosed under the aged of 15 revealing a 5- (RR = 5.1; 95% CI, 3.3-7.9) and 44-fold (RR = 44.6; 95% CI, 18.4-108.3) increased risked of cancer compared with the Australian population, respectively. About 2% of CCS reported that they had been diagnosed with a genetic cancer syndrome. However, 11% of survivors described a family history pattern which met Chompret criteria for screening for TP53 mutations associated with LFS. Our data suggests that familial cancer predispositions may be initially overlooked. Aperiodic and accurate ascertainment of family cancer history of childhood cancer patients and survivors is therefore recommended.

More than 20-year follow-up of A-bomb survivors in Hiroshima and Nagasaki has a crucial role in determining the relationship of radiation to the occurrence of breast cancer. In 1967, Wanebo et al have first reported 27 cases of breast cancer during the period 1950-1966 among the Adult Health Study population of A-bomb survivors. Since then, follow-up surveys for breast cancer have been made using the Life Span Study (LSS) cohort, and the incidence of breast cancer has increased year by year; that is breast cancer was identified in 231 cases by the first LSS series (1950-1969), 360 cases by the second LSS series (1950-1974), 564 cases by the third LSS series (1950-1980), and 816 cases in the fourth LSS series (1950-1085). The third LSS series have revealed a high risk for radiation-induced breast cancer in women aged 10 or less at the time of exposure (ATE). Both relative and absolute risks are found to be decreased with increasing ages ATE. Based on the above-mentioned findings and other studies on persons exposed medical radiation, radiation-induced breast cancer is characterized by the following: (1) the incidence of breast cancer is linearly increased with increasing radiation doses; (2) both relative and absolute risks for breast cancer are high in younger persons ATE; (3) age distribution of breast cancer in proximally exposed A-bomb survivors is the same as that in both distally A-bomb survivors and non-exposed persons, and there is no difference in histology between the former and latter groups. Thus, immature mammary gland cells before the age of puberty are found to be most radiosensitive. (N.K.)

We have studied the detection of hepatic tumor by single photon emmision computed tomography (SPECT) using rotatory chair and gamma camera. SPECT were taken by multiple section slice not in transaxial but also in frontal and sagital view. The detectability of SPECT turned out to be superior to the conventional liver scintiphoto. By SPECT, minute hepatocellular carcinoma (HCC) of 1.9 cm in diameter was detectable. Simultaneous interpretation of SPECT, US and XCT was more helpful than each independent interpertation. Subject comprised 108 patients with focal hepatic lesions including 48 cases of HCC and 44 cases of metastatic liver tumor. SPECT and celiac angiography on a 63-year-old female with liver cirrhosis revealed hepatic mass lesion in subphrenic region in right hepatic lobe, but XCT or US could not detect any lesion of hepatic tumor. Operated specimen showed confluent-massive type of HCC according to Nakashima's classification with 7 x 7 x 6.5 cm in size, representing replacing proliferation by histological examination. Both sensitivity and false positive rate of detectability of HCC were superior in decreasing order as combined three modalities, US XCT and SPECT. The diagnosis by combined three modalities shows 99% of sensitivity rate with 1% of false negative rate and 0% of false positive rate and 99.5% of accuracy. Differenciation of HCC from metastatic liver cancer or another benign tumor was possible with sensitivity rate of 94.8% and specificity rate of 90.0% by three combined modalities.

HyGenSys: a Flexible Process for Hydrogen and Power Production with Reduction of CO2 Emission HyGenSys : un procédé flexible de production d’hydrogène et d’électricité avec réduction des émissions de CO2

Directory of Open Access Journals (Sweden)

Giroudière F.

2010-09-01

Full Text Available This paper presents the latest development of HyGenSys, a new sustainable process and technology for the conversion of natural gas to hydrogen and power. The concept combines a specific steam reforming reactor-exchanger with a gas turbine. The heat necessary for the steam reforming reaction comes from hot pressurized flue gases produced in a gas turbine instead of a conventional furnace. Thanks to this high level of heat integration, the overall efficiency is improved and the natural gas consumption is reduced which represents an advantage with regard to economics and CO2 emission reduction. In addition to the efficient HyGenSys process scheme itself, the technology of the reactorexchanger also offers a high level of heat integration for even more energy saving. Two main alternatives are examined in order to meet two different requirements. The first one, named HyGenSys-0, focuses on the hydrogen production for the refining and petrochemical application. The second one named HyGenSys-1, concerns the centralized power production with pre-combustion CO2capture. In that case, the produced hydrogen is fully used to fuel a power gas turbine. HyGenSys-1 has been developed and optimised in CACHET, a European Community funded project. The CACHET electrical power objective was 400 MW at the minimum. HyGenSys-0 and HyGenSys-1 are described in detail with challenges and advantages compared to existing technologies. For both alternatives, the heart of the technology is the reactor-exchanger. The reactor-exchanger design relies on an innovative arrangement of bayonet tubes that allows, at large scale, multiple heat exchanges between hot pressurized flue gas, natural gas feed and hydrogen rich stream produced. Cet article présente les développements récents d’HyGenSys, nouvel éco-procédé de conversion du gaz naturel en hydrogène et électricité. Le concept combine un réacteur-échangeur spécifique de reformage à la vapeur avec une turbine à gaz

Gastric cancer

Salek, T.

2007-01-01

Gastric cancer is still a major health problem and a leading cause of cancer mortality despite a worldwide decline in incidence. Primarily due to early detection of the disease, the results of treatment for gastric cancer have improved in Japan, Korea and several specialized Western centres. Surgery offers excellent long-term survival results for early gastric cancer (EGC). In the Western world, however more than 80 % of patients at diagnosis have an advanced gastric cancer with a poor prognosis. The aim of surgery is the complete removal of the tumour (UICC R0-resection), which is known to be the only proven, effective treatment modality and the most important treatmentrelated prognostic factor. The prognosis after surgical treatment of gastric cancer remains poor. Neoadjuvant chemotherapy is a rising option in locally advanced gastric cancer. Adjuvant chemoradiation has been shown to be beneficial in gastric cancer patients who have undergone suboptimal surgical resection. The benefits of adjuvant chemotherapy alone seem to be very small, Untreated metastatic gastric cancer is associated with a median survival of only 3 - 4 months, but this can be increased to 8 - 10 months, associated with improved quality of life, with combination chemotherapy. Currently, no standard combination chemotherapy regimen exists, although regimens utilizing both cisplatin and 5-fluorouracil, such as epirubicin/cisplatin/fluorouracil (ECF) or docetaxel/cisplatin/fluorouracil (DCF) are amongst the most active. Newer chemotherapeutic agents, including irinotecan, oxaliplatin and taxanes, show promising activity, and are currently being tested with biologics in clinical trials. (author)

Cancer has been a major cause of death world wide and in Nigeria there are six commonest forms of manifestation of cancer known. Of these prostrate cancer is the highest with 16% occurrence of all known cancers according to a study by the Histopathology Department of the UCH. Many factors, amongst them dietary, environmental, lifestyle, age and sedentary work are possible causes. With the global rise in incidents, the IAEA initiated the Tumour Marker Project as a means of screening cancers in 15 African countries including Nigeria. In Nigeria, 4 groups of the commonest cancers have been chosen for screening. These are prostrate cancer, primary liver cancer, cancer of the GI tract and trophoblastic cancer

Benjamin; Wolfson; Gabriel; Eades; Qun; Zhou

2015-01-01

Signaling within the tumor microenvironment has a critical role in cancer initiation and progression. Adipocytes, one of the major components of the breast microenvironment,have been shown to provide pro-tumorigenic signals that promote cancer cell proliferation and invasiveness in vitro and tumorigenicity in vivo. Adipocyte secreted factors such as leptin and interleukin-6(IL-6) have a paracrine effect on breast cancer cells. In adipocyte-adjacent breast cancer cells, the leptin and IL-6 signaling pathways activate janus kinase 2/signal transducer and activatorof transcription 5, promoting the epithelial-mesenchymal transition, and upregulating stemness regulators such as Notch, Wnt and the Sex determining region Y-box 2/octamer binding transcription factor 4/Nanog signaling axis. In this review we will summarize the major signaling pathways that regulate cancer stem cells in breast cancer and describe the effects that adipocyte secreted IL-6 and leptin have on breast cancer stem cell signaling. Finally we will introduce a new potential treatment paradigm of inhibiting the adipocyte-breast cancer cell signaling via targeting the IL-6 or leptin pathways.

This study was designed to investigate the role of PDGF-DD secreted by gastric cancer-derived mesenchymal stem cells (GC-MSCs) in human gastric cancer progression. Gastric cancer cells were indirectly co-cultured with GC-MSCs in a transwell system. The growth and migration of gastric cancer cells were evaluated by cell colony formation assay and transwell migration assay, respectively. The production of PDGF-DD in GC-MSCs was determined by using Luminex and ELISA. Neutralization of PDGFR-β by su16f and siRNA interference of PDGF-DD in GC-MSCs was used to demonstrate the role of PDGF-DD produced by GC-MSCs in gastric cancer progression. GC-MSC conditioned medium promoted gastric cancer cell proliferation and migration in vitro and in vivo. Co-culture with GC-MSCs increased the phosphorylation of PDGFR-β in SGC-7901 cells. Neutralization of PDGFR-β by su16f blocked the promoting role of GC-MSC conditioned medium in gastric cancer cell proliferation and migration. Recombinant PDGF-DD duplicated the effects of GC-MSC conditioned medium on gastric cancer cells. Knockdown of PDGF-DD in GC-MSCs abolished its effects on gastric cancer cells in vitro and in vivo. PDGF-DD secreted by GC-MSCs is capable of promoting gastric cancer cell progression in vitro and in vivo. Targeting the PDGF-DD/PDGFR-β interaction between MSCs and gastric cancer cells may represent a novel strategy for gastric cancer therapy.

Human papillomavirus in cervical cancer and oropharyngeal cancer: One cause, two diseases.

Science.gov (United States)

Berman, Tara A; Schiller, John T

2017-06-15

Human papillomavirus (HPV) causes greater than 5% of cancers worldwide, including all cervical cancers and an alarmingly increasing proportion of oropharyngeal cancers (OPCs). Despite markedly reduced cervical cancer incidence in industrialized nations with organized screening programs, cervical cancer remains the second most common cause of death from cancer in women worldwide, as developing countries lack resources for universal, high-quality screening. In the United States, HPV-related OPC is only 1 of 5 cancers with a rising incidence since 1975 and now has taken over the cervix as the most common site of HPV-related cancer. Similar trends follow throughout North America and Europe. The need for early detection and prevention is paramount. Despite the common etiologic role of HPV in the development of cervical cancer and HPV-associated OPC, great disparity exists between incidence, screening modalities (or lack thereof), treatment, and prevention in these 2 very distinct cohorts. These differences in cervical cancer and HPV-associated OPC and their impact are discussed here. Cancer 2017;123:2219-2229. © 2017 American Cancer Society. Published 2017.

2014-07-01

Full Text Available Background. This paper details the role of different dimensions of health literacy in the relationship between health literacy and cancer-related health behaviours. In particular, Cancer Literacy is studied as an exemplar of a dimension of health literacy beyond basic reading and writing skills. The link between functional health literacy, Cancer Literacy and cancer-related health behaviours is investigated in a sample of Ticino (Switzerland residents (n=639. Design and methods. Detailed data is collected about respondents’ functional health literacy, Cancer Literacy, cancer information seeking behaviour, engagement in cancer preventive behaviours, participation to cancer screenings, and intention to adhere to current screening recommendations. Results. Results confirm the added value of Cancer Literacy – compared to functional health literacy – in explaining people’s cancer information seeking behaviour, their participation to several cancer screenings and their screening intention, underscoring the need to take into account dimensions of health literacy beyond basic functional skills. Conclusions. From a public health perspective, findings provide further evidence on the importance of adapting informational and educational communication intervention designed to improve cancer prevention and screening to different audiences.

Introduction. - Between May 2002 and May 2004, eight French comprehensive cancer centres did a prospective non-randomized study including 200 patients, 100 with cancer of the prostate and 100 with head and neck cancers. Half of each patient group was treated by IMRT and the others by RTC 3D. This clinical study was associated with an economic study and a physics study. We report here the first results. Patients and methods. - For the clinical study, the analysis of the data of the first 88 patients irradiated for a prostatic cancer shows that 39 received RTC and 49 IMRT with a mean dose of 78 Gy at the ICRU point at 2 Gy per fraction. For H and N tumours, the preliminary analysis was done on the 87 first patients with a mean follow-up of 11.5 months (2 to 25 months) and a median of 8.4 months for the IMRT groups and 13,2 months for the RTC group. The economic study was done on the first 157 patients included during the first 18 months: 71 treated by RTC (35 for H and N and 36 for prostate) and 86 treated by IMRT (38 for H and N and 48 for prostate). The assessment of the direct costs was realized y a micro-costing technique. The physical study compared dose distributions for both techniques and has created quality control recommendations. Results. - Clinical studies of the acute reactions do not show any difference between groups, but we want to point out the short follow-up and the relatively high dose delivered to cancers of the prostate. The physics study demonstrates that IMRT is technically feasible in good clinical conditions with high quality assurance, a good reproducibility and precision. Dosimetric data show that IMRT could certainly spare organs at risk more than RTC for H and N tumours. The direct costs of 'routine' treatments for H and N tumours were 4922 euros for IMRT versus 1899 euros for RTC and for the prostatic cancers 4911 euros for IMRT versus 2357 for RTC. (authors)

The role of stress in relation to cancer remains controversial. Stress is assumed to be an emerging public health problem in modern society. Still, we argue that it is relevant to view the role of stress in cancer from a scientific point of view. A critical overview of existing evidence...... is presented through previous review studies, and the importance of methodological challenges is highlighted. We summarize the evidence on the role of stress as a cause of cancer, on the impact of stress on cancer prognosis, and on how coping mechanisms may influence stress levels in cancer patients. Finally......, we describe the evidence on interventions to relieve stress in cancer patients for the purpose of improving both well-being and cancer prognosis. Against public opinion, we critically dismiss the evidence on psychotherapy as a tool to prolong life after cancer as inconsistent and unresolved....

Ovarian Cancer Stroma: Pathophysiology and the Roles in Cancer Development

Ovarian cancer represents one of the cancers with the worst prognostic in adult women. More than half of the patients who present with clinical signs such as abdominal bloating and a feeling of fullness already show advanced stages. The majority of ovarian cancers grow as cystic masses, and cancer cells easily spread into the pelvic cavity once the cysts rupture or leak. When the ovarian cancer cells disseminate into the peritoneal cavity, metastatic nests may grow in the cul-de-sac, and in more advanced stages, the peritoneal surfaces of the upper abdomen become the next largest soil for cancer progression. Ascites is also produced frequently in ovarian cancers, which facilitates distant metastasis. Clinicopathologic, epidemiologic and molecular studies on ovarian cancers have improved our understanding and therapeutic approaches, but still further efforts are required to reduce the risks in the patients who are predisposed to this lethal disease and the mortality of the patients in advanced stages. Among various molecules involved in ovarian carcinogenesis, special genes such as TP53, BRCA1 and BRCA2 have been well investigated. These genes are widely accepted as the predisposing factors that trigger malignant transformation of the epithelial cells of the ovary. In addition, adnexal inflammatory conditions such as chronic salpingitis and ovarian endometriosis have been great research interests in the context of carcinogenic background of ovarian cancers. In this review, I discuss the roles of stromal cells and inflammatory factors in the carcinogenesis and progression of ovarian cancers

The Implications of Cancer Stem Cells for Cancer Therapy

Full Text Available Surgery, radiotherapy and chemotherapy are universally recognized as the most effective anti-cancer therapies. Despite significant advances directed towards elucidating molecular mechanisms and developing clinical trials, cancer still remains a major public health issue. Recent studies have showed that cancer stem cells (CSCs, a small subpopulation of tumor cells, can generate bulk populations of nontumorigenic cancer cell progeny through the self-renewal and differentiation processes. As CSCs are proposed to persist in tumors as a distinct population and cause relapse and metastasis by giving rise to new tumors, development of CSC-targeted therapeutic strategies holds new hope for improving survival and quality of life in patients with cancer. Therapeutic innovations will emerge from a better understanding of the biology and environment of CSCs, which, however, are largely unexplored. This review summarizes the characteristics, evidences and development of CSCs, as well as implications and challenges for cancer treatment.

Metastatic gastric cancer is uncommon, and metastasis of colorectal cancer to the stomach is extremely rare. We report a case of metastatic gastric cancer that originated from transverse colon cancer. A 52-year-old woman underwent a left hemicolectomy and D3 lymph node dissection based on a diagnosis of transverse colon cancer. The pathology results were as follows: mucinous adenocarcinoma, type 2, 6 × 11 cm, ss, ly1 v1, pm (-), dm (-), n1 (+), P0, H0, M0, Stage IIIa. The patient received XELOX as postoperative adjuvant therapy for 6 months. One year and 3 months after the left hemicolectomy, gastroscopy revealed a submucosal tumor in the lower body of the stomach and an incipient cancer in the cardia of the stomach, and a colonoscopy revealed an incipient cancer in the transverse colon. An endoscopic ultrasonography fine needle aspiration biopsy of the submucosal tumor in the lower body of the stomach was performed. Histology showed that this tumor was a mucinous adenocarcinoma similar to the primary transverse colon cancer, which led to a diagnosis of metastatic gastric cancer originating from transverse colon cancer. Distant metastasis was not detected. Endoscopic submucosal dissection of the incipient gastric cancer was performed, as were distal gastrectomy and partial colectomy. Peritoneal dissemination and para-aortic lymph node recurrence were detected 7 months after the second surgery.
