La extirpación del ganglio centinela es una técnica quirúrgica muy extendida cuyo objetivo es evitar el vaciamiento axilar en pacientes con cáncer de mama en estadios iniciales. La determinación de la infiltración tumoral puede ser evidente en caso de macrometástasis (>2mm, o difícil de detectar en las micrometástasis (2mm, 5 fueron micrometástasis Background. The extirpation of the sentinel node is a widespread surgical technique whose aim is to avoid axillary resection in patients with breast cancer at early stages. Determination of tumoral infiltration can be evident in the case of macrometastasis (>2mm, or difficult to detect in micrometastasis (2mm, 5 were micrometastases <2mm and 3 were isolated cellular groups (between 0.2 and 2mm. In 6 cases (43%, the metastases only became evident with queratine staining in serialized cuts. Axillary resection was carried out in 44 cases. Conclusions. The histological study of the sentinel nodes makes it possible to evaluate the status of tumoral infiltration of the axillary ganglions and to greatly reduce axillary lymphadenectomies. The conventional study of the sentinel node (with a single section is insufficient for the diagnosis of tumoral infiltration. In our series, histological study using a protocol of serialized sections has enabled us to detect some 43% of metastases in the sentinel node that were not evident in the initial section.

    Full Text Available El melanoma cutáneo es una neoplasia cuya incidencia va en aumento en nuestro medio. Presentamos un estudio sobre 1023 casos de esta patología recogidos a lo largo de 20 años, distribuidos en 2 grupos: grupo A tratados antes del 2000, y grupo B tratados después del 2000. Comparamos la supervivencia de ambos grupos en base al cambio de tratamiento por la introducción del estudio del ganglio centinela a partir del año 2000. No observamos diferencias significativas entre los 2 grupos en la supervivencia de los pacientes con melanoma a pesar de realizar tratamientos más conservadores. Por tanto, gracias a la biopsia de ganglio centinela, se pueden evitar un 75% de linfadenectomías electivas realizadas en este tipo de patología sin modificar los índices de supervivencia.

    ABSTRACT

    A COMPARISON BETWEEN DIFFERENT SENTINEL NODE DETECTION TECHNIQUES AFTER NEOADJUVANCY IN BREAST CANCER

     

    Introduction. Since the role of sentinel node biopsy after neoadjuvant chemotherapy is controversial, the aim of our study was to analyze the value of sentinel node detection in advanced breast tumors that received neoadjuvant therapy. Technical study was done with hematoxylin/eosin stain, immunohistochemistry and molecular polymerase chain reaction (RT-PCR. Material and methods:We studied 33 patients who received neoadjuvant therapy and underwent sentinel node procedure. After removing the node, it was sent to pathology where it was evaluated; further fragments, using between 25% and 50% of the lymph node, were used for analysis at the molecular biology laboratory. 

    Results: The sentinel nodes were studied with hematoxylin and eosin, immunohistochemistry and molecular techniques, finding an increase in sensitivity with RT-PCR. They were negative in 45.1% and lymphadenectomy tissue was negative in 61.3% after neoadjuvant therapy. Local recurrences at 5 years are equivalent to 8.3%. For our series the rate of disease-free survival at 5 years in stage II is 100% and stage III is 87.5%. Conclusion. Sentinel node biopsy after neoadjuvant therapy for breast cancer should only be a matter of research, since the number of studied patients is small and there have been no monitoring to endorse a wide use of the procedure. When comparing hematoxylin

La cara y el cuello son zonas del cuerpo con una alta exposición solar, reflejándose en un mayor número de casos de este sombrío tumor. El mayor factor pronóstico en contra de los pacientes que padecen esta enfermedad es la presencia de metástasis ganglionares, por eso el grupo tratante debe esclarecer si están presentes, debido a esto hace varias décadas se realizan disecciones de cuello profilácticas, pero en la mayoría de los casos los ganglios extirpados son negativos. Una posible solución para evitar esto, es la extracción del o de los primeros ganglios que drenan el sitio del tumor primario (Ganglio Centinela.

M ultimeric radiopharmaceuticals prepared from kit showed a radiochemical purity of 96 {+-} 2%. The far-infrared spectra showed a characteristic band at 279 {+-} 1 cm{sup -1}, which was assigned to the Au-S bond. UV-Vis and XP S also indicated that the Au-Np were functionalized with peptides or mannose. Radiopharmaceuticals showed specific recognition for receptors expressed in cancer cells or rat liver cells. Micro-SPECT/CT images showed clear tumour uptake and lymph node accumulation. The kit demonstrated excellent stability during storage at 4 C for 6 months. This study demonstrated that {sup 99m}Tc-Au-Np-mannose remains within the first lymph node during 24 h and therefore might be useful as a target-specific radiopharmaceutical for SLND using 1-day or 2-day conventional protocols. Likewise, m ultimeric systems of {sup 99m}Tc-Au-Np-mannose, {sup 99m}Tc-Au-Np-RGD and {sup 99m}Tc-Au-Np-Lys{sup 3}-bombesin prepared from kits exhibited properties suitable as target-specific agents for molecular imaging of tumours and sentinel lymph node.

    A systematic survey of expression profiles of glycosphingolipids (GSLs) in two hESC lines and their differentiated embryoid body (EB) outgrowth with three germ layers was carried out using immunofluorescence, flow cytometry, and MALDI-MS and MS/MS analyses. In addition to the well-known hESC-specific markers stage-specific embryonic antigen 3 (SSEA-3) and SSEA-4, we identified several globosides and lacto-series GSLs, previously unrevealed in hESCs, including Gb(4)Cer, Lc(4)Cer, fucosyl Lc(4)Cer, Globo H, and disialyl Gb(5)Cer. During hESC differentiation into EBs, MS analysis revealed a clear-cut switch in the core structures of GSLs from globo- and lacto- to ganglio-series, which was not as evident by immunostaining with antibodies against SSEA-3 and SSEA-4, owing to their cross-reactivities with various glycosphingolipids. Such a switch was attributable to altered expression of key glycosyltransferases (GTs) in the biosynthetic pathways by the up-regulation of ganglio-series-related GTs with simultaneous down-regulation of globo- and lacto-series-related GTs. Thus, these results provide insights into the unique stage-specific transition and mechanism for alterations of GSL core structures during hESC differentiation. In addition, unique glycan structures uncovered by MS analyses may serve as surface markers for further delineation of hESCs and help identify of their functional roles not only in hESCs but also in cancers.

Such a switch was attributable to altered expression of key glycosyltransferases (GTs) in the biosynthetic pathways by the up-regulation of ganglio-series–related GTs with simultaneous down-regulation of globo- and lacto-series–related GTs. Thus, these results provide insights into the unique stage-specific transition and mechanism for alterations of GSL core structures during hESC differentiation. In addition, unique glycan structures uncovered by MS analyses may serve as surface markers for further delineation of hESCs and help identify of their functional roles not only in hESCs but also in cancers.

    Full Text Available Los sedimentos denominados informalmente "pampeanos" son reconocidos como un paquete de limos y limos arenosos depositados desde el Plioceno superior hasta el Pleistoceno superior, con dos intercalaciones marinas hacia el este, reconocidas fundamentalmente por acumulaciones de valvas marinas: el Interensenadense, y el Belgranense. En el oeste de la provincia de Buenos Aires una extensa área ha sido denominada Mar de arena. En canales próximos a Daireaux y en acantilados marinos de Centinela del Mar, se describieron depósitos arenosos con estratificación diagonal de mesoescala que prueban la presencia de campos de arena por debajo de los depósitos limosos. Las edades del Pleistoceno superior han sido confirmadas por las asociaciones de vertebrados recuperados. En Centinela del Mar, la edad de estos médanos transversales que conformaban una barrera litoral ha sido también confirmada por su vinculación con el máximo nivel del mar alcanzado durante el interglacial Sangamon (Pleistoceno superior, 120.000 años AP.

    Full Text Available El presente trabajo corresponde una revisión bibliográfica de los estudios clínicos realizados en síndromes anginosos refractarios al tratamiento convencional, utilizando como tratamiento el bloqueo de ganglio estrellado. Se realizó una búsqueda de literatura publicada entre los años 1.900 al 2.000 en las bases de datos MDConsult, Medline y ProQuest. A su vez se revisaron las publicaciones en la Biblioteca del Hospital Rafael Ángel Calderón Guardia y en la Biblioteca del BINASSS (Biblioteca Nacional de Salud del Seguro Social. De acuerdo a los estudios analizados el bloqueo de ganglio estrellado se describe como posibilidad terapéutica para el control de dolor de la angina de pecho refractaria . La descripción clásica de la inervación cardíaca consiste en tres nervios simpáticos mayores originados de los ganglios cervicales superior, medio e inferior. Esta inervación simpática en conjunto con diversos nervios parasimpáticos, se describen como el plexo cardíaco. En contraste Jane et. al. (1986 en un estudio anatómico de 23 cadáveres describe que la inervación cardiopulmonar en el hombre se origina en el ganglio estrellado y las mitades caudales de las cadenas simpáticas cervicales junto con nervios que se originan del nervio recurrente laríngeo o del vago. De estas estructuras derivan los dos plexos cardiopulmonares. De estos plexos derivan tres nervios cardíacos mayores que se proyectan hacia el corazón. Se estima que determinado porcentaje de los pacientes diagnosticados con angina inestable progresará a desarrollar una angina refractaria al tratamiento. El bloqueo de ganglio estrellado podría ser un nuevo método terapéutico para controlar el dolor de dicha condición. Sin embargo se necesitan estudios clínicos randomizados a doble ciego para obtener resultados concluyentes.

    In the present paper, the geomorphologic and sedimentary characteristics of the continental sequences exposed on the coastal cliffs and surrounding areas of the Centinela del Mar locality are described and interpreted. Fourteen lithofacies are defined, their relation, geometry and structure are represented using transversal and longitudinal detailed profiles. In the basal and medium sector of the profile, facies of different degrees of transport and aqueous rework were recognized. In the superior sector, a succession of marine peri-coastal facies corresponding to the Belgranense transgression (=Fm. Pascua) were identified, ending the sequence with relictual eolic facies. The different historical interpretations are discussed, homologating the units referred previously with the ones proposed on this paper. These units are correlated with those defined in the allostratigrapic scheme proposed by other authors for the area covered between Playa San Carlos and Arroyo Chapadmalal. This allowed recognize for the area under study the presence of the Punta San Andres and Arroyo Loberia Alloformations (basal-medium and superior sector, respectively). Between these two entities, a association of well defined progradant marine facies are found and named on this paper as Centinela del Mar Alloformation. Finally, periferithe information gathered here (magnetostratigraphy, radiometric dating, stratigraphic correlations, etc) indicates, at least preliminarily, that the sequence of Centinela del Mar corresponds to the Ensenadense- Lujanense interval (Lower Pleistocene - Holocene).

Contrariamente, en los ganglios linfáticos el número de células Treg y su frecuencia dentro de la población CD4+ se incrementaron. La ausencia de actividad de CTSL en las células CD4+ de los ganglios linfoides -y no en su entorno- incrementó su tasa de proliferación. Las células Treg y las T CD4+ convencionales (CD4+CD25-Foxp3- de los ratones mutantes mostraron aumentos similares en su tasa de proliferación, sugiriendo que la proliferación contribuye al incremento en el número de células Treg, pero el aumento en su frecuencia no derivaría exclusivamente del incremento en su proliferación. Por otra parte, no se observó una disminución en los niveles de apoptosis de células Treg. Teniendo en cuenta que la producción diaria de timocitos CD4+ está disminuida en los ratones CTSLnkt/nkt, estos resultados sugieren que el incremento de células Treg en los ganglios linfoides de estos mutantes no derivaría de una mayor exportación tímica, y permiten hipotetizar que la ausencia de actividad de CTSL favorecería la adquisición del fenotipo CD4+CD25+Foxp3+ a partir de células CD4+CD25-Foxp3- en la periferia.

La presencia de ganglios linfáticos con micrometástasis en muchos casos no puede ser detectada por técnicas rutinarias. Se estudiaron prospectivamente 162 ganglios linfáticos de 30 pacientes con carcinoma de colon, los cuales según los resultados de las técnicas rutinarias fueron clasificados como Dukes A (2, Dukes B (19 y Dukes C (9. Un paciente con enfermedad colónica benigna se uso como control negativo. Todos los ganglios se seccionaron en mitades, una de las cuales se almacenó en nitrógeno líquido para su ulterior estudio por técnicas de biología molecular, mediante la expresión del antígeno carcinoembrionario (CEA. La otra mitad fue fijada en formaldehído e incluida en parafina para su estudio anatomopatológico e inmunohistoquímico. Del total de los casos se detectó un aumento del 50% de la sensibilidad en la detección de micrometástasis mediante la reacción en cadena de la polimerasa con transcriptasa reversa (RT-PCR para los Dukes A-B y se detectó la expresión de dicho antígeno en el total de los casos Dukes C.

    Full Text Available The purpose of this study was to characterize and quantify cells involved in immune response in metastasis-free regional lymph nodes (RLNs draining different human epithelial tumors and compare them (by immunohistochemistry with control lymph nodes from patients with non malignant diseases. We showed that T cells number was decreased in RLNs as compared to the controls with reduction in both CD4+ T cells and CD8+ T cells subsets and an inverted ratio (CD4+: CD8+. B lymphocytes and follicular dendritic cells were decreased with respect to the controls. S100+ dendritic cells (DCs and mature DCs were detected in T dependent areas. Their mean number was significantly lower as compared to control. Immature DCs were significantly diminished compared to RLN and control nodes. CD57+ cells, follicular T helper cells and/or NK cells, were localized in the clear zone of germinal centres and their mean number was significantly increased. There were no CD57+ cells in hypoplastic follicles. In this study we show that RLNs draining human cancer present reduction in almost all immune cells, except CD57+ cells. These findings may be related to the deficient anti-tumor immune response in patients with cancer and subsequent tumor progression.El objetivo del trabajo fue caracterizar y cuantificar utilizando inmuno-histoquímica, las células involucradas en la respuesta inmune en ganglios linfáticos regionales (GLRs que drenan distintos tumores epiteliales malignos humanos y compararlas con ganglios controles (GLCs provenientes de pacientes sin enfermedad neoplásica maligna.

    Glycosphinogolipids bearing GlcNAc{beta}1 {yields} 3 and GalNAc{beta}1 {yields} 4 linked to {beta}-Gal of lactosylceramide first isolated from a murine myelogenous leukemia cell line have since been found as normal components of mullet roe and English sole liver. In order to clarify the biosynthetic pathways responsible for its occurrence both as a product of normal tissues and as a possible mammalian cancer-associated antigen, the lacto-ganglio hybrid core structure LcGg{sub 4}Cer was synthesized from Lc{sub 3}Cer using a GalNAc{beta}1 {yields} 4 transferase preparation from English sole liver. A preliminary characterization of the enzyme, which may be identical to the GalNAc T-1 responsible for synthesis of GM{sub 2} ganglioside, is presented. The enzymatically synthesized product was analyzed by 1- and 2-D {sup 1}H NMR spectroscopy, confirming its primary structure as GalNAc{beta}1 {yields} 4-(GlcNAc{beta}1 {yields} 3)Gal{beta}1 {yields} 4Glc{beta}1 {yields} 1Cer. An approximate three-dimensional structure for LcGg{sub 4}Cer is proposed, consistent with all data obtained, which should be useful in discussing the results of {sup 1}H NMR analysis of compounds containing this core tetrasaccharide. The structure is characterized by an unusual arrangement of terminal N-acetylhexosamine residues, resulting in a {pi}-H hydrogen-bonding interaction between their acetamido groups.

    We have analyzed the glycolipid markers of a recently cloned human embryonal carcinoma (EC) cell line, NTERA-2, which differentiates extensively into a variety of somatic cell types when exposed to retinoic acid. These tumor cells provide a model system that can be used to study the ontogeny of glycolipid diversity during human embryonic development. Glycolipid antigens were identified by cell surface immunofluorescence and thin-layer chromatography immunostaining using a comprehensive set of anticarbohydrate monoclonal antibodies. Undifferentiated NTERA-2 cells were found to express predominantly globo-series glycolipids, including Gb3, Gb5 (IV3GalGb4), globo-ganglioside (IV3NeuAc alpha 2----3GalGb4), globo-H (IV3Fuc alpha 1----2GalGb4), and globo-A (IV3GalNAc alpha 1----3[Fuc alpha 1----2]GalGb4). When NTERA-2 cells were induced to differentiate by culturing in the presence of 10(-5) M retinoic acid, a remarkable shift of cellular glycolipids from globo-series to lacto- and ganglio-series was observed: Globo-series structures declined, particularly during the period 7-20 days after first exposure to retinoic acid, while lacto-series structures, including fucosyl alpha 1----3 type 2 chain (Lex) and sialosyl type 2 chain, and ganglio-series structures, including GM3, GD3, 9-O-acetyl-GD3, GM2, GD2, and GT3, increased. The presence of globo-A and globo-H as the major ABH blood group antigens in undifferentiated NTERA-2 cells suggests that globo-series blood group antigens are embryonic antigens, synthesis of which switches to lacto-series during human development. Two-color immunofluorescence analysis indicated preferential expression of several ganglio- and lacto-series antigens on different subsets of differentiated cells and permitted the relationship of these subsets to the development of neurons in NTERA-2 cultures to be determined. The results suggest that glycosyltransferase, particularly those involved in controlling glycoconjugate core structure assembly

    Full Text Available Las redes centinela sanitarias han estado activas en nuestro país desde la década de los años ochenta, con variados objetivos, metodología y diferente grado de desarrollo en las comunidades autónomas donde se han implantado. La necesidad de normalizar el funcionamiento y de armonizar los indicadores ha propiciado un proyecto de investigación de redes centinela sanitarias españolas, uno de cuyos objetivos es establecer una guía de principios y métodos de trabajo. Se ha procedido a realizar un estudio con el método Delphi, en el que un panel de 23 expertos ha consensuado, en 3 fases consecutivas, la definición de red centinela, los objetivos, los principios que deben regirlas y otros aspectos relacionados con la organización y funcionamiento. En conjunto se plantearon 41 cuestiones sobre la base de un primer borrador, las cuales necesitaban un 80% de consenso en una primera fase y un 70% en la segunda. Todos los expertos participaron en la primera fase, 22 en la segunda y 20 en la tercera. Se alcanzó un consenso en 36 cuestiones en la primera fase y en 4 de las 5 restantes en la segunda. En la tercera fase se dio forma definitiva al documento de la guía. El método de consenso Delphi ha resultado extremadamente útil en la resolución de discrepancias y divergencias, obteniéndose una guía válida para redes centinela. Los expertos ajenos a los sistemas centinela del panel seleccionado aportaron una visión más extensa sobre los objetivos y la aplicabilidad de las redes centinela sanitarias en España.Since the eighties, health sentinel networks have been active in our country, but with a variety of objectives, methods and different development levels in the autonomous communities.

    Los cultivos de ganglio espinal son utilizados para estudiar la interacción entre el virus de la rabia y las neuronas sensoriales presentes en ellos. Se conoce que in vivo, el virus utiliza estas neuronas como una de las puertas de entrada al Sistema Nervioso Central en donde posteriormente se produce una encefalopatía letal. La patología producida por el virus es debida a su marcado tropismo hacia las neuronas, que depende a su vez de la unión entre el virus y receptores específicos en la membrana neuronal. Entre las moléculas que se han reportado como posibles receptores virales están el Receptor Nicotínico de Acetilcolina (RNACh, la Molécula de Adhesión Celular Neuronal (NCAM y el receptor de baja afinidad para las neurotrofinas (p75NTR. Se sabe que en cultivos de neuronas sensoriales adultas, las neurotrofinas pueden promover la regeneración neurítica y mantener los fenotipos neuronales. Además existe evidencia de que en líneas celulares el Nerve Growth Factor (NGF modifica la calidad y cantidad de RNACh y NCAM expresados, así en estos cultivos primarios (que expresan toda clase de receptores para neurotrofinas se pudieran estar presentando también tales cambios, que conlleven a modificaciones en la infección por el virus de rabia. De esta manera, el objetivo de este estudio, fue evaluar el efecto de las neurotrofinas sobre la regeneración neurítica y la supervivencia neuronal (en cultivos no infectados y sobre la proporción de células infectadas por virus de rabia. Para ello, los cultivos se trataron desde el inicio con NGF, Brain-Derived Neurotrophic Factor (BDNF y Neurotrophin-3 (NT-3 a tres diferentes concentraciones y algunos de ellos fueron infectados con virus de la rabia, cepa CVS (Challenge Virus Standard obtenido en cerebro de ratón.

    El virus de la rabia presenta un fuerte tropismo neuronal y que produce una encefalitis generalmente letal. En un accidente rábico clásico, producido por la mordedura de un animal infectado, el virus es captado por terminaciones nerviosas motoras, autonómicas o sensoriales. Si es captado por estas últimas, el virus se transporta retrógradamente hacia los somas neuronales ubicados en los ganglios espinales y de ahí pasa hasta el Sistema Nervioso Central en donde ejerce su acción patógena. Por este motivo los cultivos de ganglio espinal son un modelo relevante para estudiar la interacción entre el virus de la rabia y las neuronas sensoriales presentes en ellos. En estos cultivos se encuentran dos tipos de células, neuronas y células no neuronales (fibroblastos y células de Schwann. Al inocular los cultivos con virus de rabia cepa CVS (Challenge Virus Standard, a pesar de que las células no neuronales son la mayoría, las que se infectan en mayor proporción son las neuronas, lo que confirma el marcado neurotropismo del virus. Adicionalmente a esto, dentro de la población neuronal, parece existir una subpoblación con mayor susceptibilidad hacia la infección por el virus. Para comprobar esta hipótesis, se caracterizaron las subpoblaciones neuronales presentes en estos cultivos utilizando un criterio morfológico (diámetro neuronal y uno bioquímico (presencia de neuropéptidos como marcadores de subpoblaciones en el ganglio. Se realizó una técnica de doble inmunocitoquímica para virus rábico y los neuropéptidos Sustancia P (SP, Neuropéptido Y (NPY, Galanina (GAL, Péptido Relacionado con el Gen de la Calcitonina (CGRP y Péptido Intestinal Vasoactivo (VIP, que clásicamente se usan para la definición de subpoblaciones.

Objetivo: Considerar la adherencia a los multimicronutrientes y los factores asociados. Métodos: Estudio epidemiológico de vigilancia activa por sitios centinela en 2.024 niños entre los 6 hasta los 35 meses atendidos en establecimientos de salud del Ministerio de Salud del Perú, entre octubre a diciembre de 2014. Se realizaron visitas domiciliarias, en las cuales se aplicaron el conteo de multimicronutrientes, que determinó la adherencia al consumo ≥ 90% de sobres, y un formulario sobre los factores asociados (conocimiento sobre anemia, alimentos ricos en hierro, efectos secundarios, esquema de dosis, medicamentos consumidos y motivación. Se emplearon estadísticas descriptivas, el test del χ², Odds Ratio con IC95% y la regresión logística binaria u OR ajustado (ORa. Resultados: 79,1% tenían entre 6 a 23 meses, 75,9% recibieron multimicronutrientes y la adherencia fue del 24,4% (IC95% 22,3 - 26,6.

La distribución geográfica fue estudiada mediante la técnica geoestadística kriging, que permite estimar la incidencia de la enfermedad en cualquier punto del territorio, a partir de la incidencia observada en unos pocos puntos estratégicamente distribuidos. Se elaboraron mapas de curvas de isoincidencia de gripe para cada semana. La valoración de la técnica se realizó mediante validación cruzada. Resultados: En la mayoría de las semanas, los valores tanto de la desviación estándar (DE reducida, como de la media reducida estuvieron cercanos a los valores considerados óptimos (0 o 1, respectivamente, y sólo en la última temporada se obtuvieron valores de la DE reducida alejados de los considerados como de buen ajuste en 12 de las 20 semanas. La estimación de tasas en todas las temporadas demostró una coherencia en su distribución espacial. También se observó coherencia en la evolución temporal. Conclusiones: En la mayoría de las situaciones los resultados pueden considerarse aceptables, no requiere recursos informáticos extraordinarios ni un empleo de tiempo excesivo, y necesita tan sólo una adaptación anual. Su facilidad de uso lo hace apto para su utilización como una técnica de rutina, pese a que puede mejorarse la precisión de las estimaciones, incrementando la complejidad del modelo.

    Full Text Available Las células de Schwann (CS son la glía del sistema nervioso periférico. Se encargan de apoyar la función
    neuronal y ayudan a la conducción del impulso nervioso. Estas células juegan un papel muy importante en el
    crecimiento axonal, no solo durante el desarrollo embrional sino durante los procesos de regeneración nerviosa. Las CS secretan un gran número de factores que promueven la regeneración y esto las ha convertido en blanco para el diseño de prótesis artificiales. Para estos estudios es necesario establecer cultivos enriquecidos de CS los cuales son realizados en general a partir de nervios periféricos, sin embargo, ciertos estudios muestran a los ganglios de la raíz dorsal (GRD como una buena fuente para la obtención de estas células. En este estudio se estableció un protocolo para la obtención de CS a partir de GRD de ratones adultos. Mediante técnicas de descapsulación, disociación enzimática y disociación mecánica fue posible establecer cultivos de CS con una pureza del 98%. Los cultivos fueron realizados sobre plástico sin afectar esto la pureza de los mismos. Este protocolo permitió la obtención de grandes poblaciones de CS (3 x 106 células/animal en tan solo un mes. Estos resultados mejoran las perspectivas del uso de los GRD como fuente para la obtención de este tipo celular.

    Full Text Available Objective: To construct a design for probabilistic sampling of reporting physicians in sentinel networks. Methods: We performed a multi-stage sample selection study. Data on primary care physicians and their patients were obtained from the Madrid Health Institute for 2005. The geographical unit of reference was the basic health area. A factorial analysis was performed on the basis of demographic, socio-cultural and socio-occupational variables. A cluster analysis was conducted to group the 247 basic health areas into homogeneous strata, which were then tested using a discriminant analysis. The general practitioners and pediatricians needed in each stratum were selected by simple random sampling. The representativeness of the population monitored by the selected physicians was studied with respect to the population of Madrid. Results: Factorial analysis yielded five factors. Using these, 14 strata were obtained, which were shown to be homogeneous and mutually different by discriminant analysis. The minimum population that needed to be monitored consisted of 146,946 adults and 24,518 children, proportionally distributed among the respective strata. Eighty-eight general practitioners and 32 pediatricians were selected, who respectively covered populations of 154,610 and 31,336 persons representative of the general population. Conclusions: Obtaining samples through suitable designs improves the accuracy of the information gathered by health sentinel networks in epidemiologic surveillance. Ensuring the representativeness of the study population vis-à-vis the general population is essential; cluster analysis and simple random sampling are methods that meet this need. Selecting physicians by means of probabilistic methods enables the accuracy of estimates to be ascertained.Objetivo: Elaborar un diseño de muestreo probabilístico de los médicos notificadores en redes centinelas sanitarias.

    Antecedentes: en pacientes con carcinoma ductal in situ la biopsia de ganglio centinela es motivo de controversia porque se reportan ganglios positivos en 1.4-12.5% debido al carcinoma invasor oculto en la pieza quirúrgica. Objetivo: conocer la frecuencia de metástasis en ganglio centinela en pacientes con carcinoma ductal in situ e identificar las diferencias entre los casos positivos y negativos. Material y métodos: estudio retrospectivo, transversal, analítico de pacientes con carcinoma ductal in situ a quienes se realizó una biopsia de ganglio centinela por requerir mastectomía, tener un tumor palpable, lesión radiológica = 5 cm, inadecuada relación mama-tumor o porque la escisión pudiera afectar el flujo linfático. Resultados: de 168 carcinomas in situ, se incluyeron 50 casos con carcinoma ductal in situ y biopsia de ganglio centinela, de pacientes con edad promedio de 51.6 años, 30 (60%) de ellas asintomáticas. Los signos reportados fueron: nódulo palpable (18%), secreción por el pezón (12%) o ambos (8%). Predominaron las microcalcificaciones (72%), comedonecrosis (62%) y grado histológico -2 (44%) con 28% de receptores hormonales negativos. En el estudio transoperatorio 4 (8%) pacientes tuvieron ganglio centinela positivo y un caso en estudio histopatológico definitivo (60% micrometástasis, 40% macrometástasis), todos con carcinoma invasor en la pieza quirúrgica. Las pacientes con ganglio centinela transoperatorio positivo eran más jóvenes (44.5 vs 51 años), con más tumores palpables (50 vs 23.1%), más grandes (3.5 vs 2 cm), más comedonecrosis (75 vs 60.8%), más indiferenciados (75% vs 39.1%) y menos receptores hormonales (50 vs 73.9%), que las que tenían ganglio centinela negativo, sin que estas diferencias tuvieran significación estadística. Conclusiones: puesto que 1 de cada 12 pacientes con carcinoma ductal in situ tiene afectación ganglionar en el ganglio centinela, se recomienda seguir tomando la biopsia para evitar

Muy poca literatura reporta cultivo de células perineurales (CP y fibroblastos endoneurales (FE, y no son consideradas como elementos a incluir en una prótesis. En este trabajo, se describe la importancia de la microdisección del nervio ciático y de los GRD para obtener cultivos de CS, FE y CP con 98%±2 de purificación. Las CS crecen sobre diferentes soportes, con y sin mitógenos. Se obtuvo un porcentaje de CS elevado cuando se elimina el epineuro y perineuro de los NC 90%±3 y la cápsula de los GRD 94%±3 antes de la disociación enzimática, comparado a 70%±4,2 sin microdisección u 80%±3,5 sin epineuro. Los FE se adhieren preferencialmente en las primeras 24 h y 20% de suero favorece su crecimiento. En el primer sub-cultivo, son 99% CS o FE, siendo confluentes a los 6 y 8 días respectivamente. Las CP o de la cápsula de GRD no se disocian y no crecen en sub-cultivos, únicamente crecen a partir de explantes de perineuro; no forman monocapa sino una "lámina" de múltiples capas celulares.

Conclusiones: El fenómeno de Raynaud tiene una prevalencia que va del 1 al 25%, en este hay una actividad simpática aumentada por lo que al realizar una simpaticolisis selectiva se logra mejorar el dolor isquémico, el cual está determinado por la insuficiencia total o parcial en el aporte de oxígeno a los tejidos, además de que tenemos bases anatómicas y fisiológicas para limitar el bloqueo a los ganglios T2 y T3, considerados como las estaciones sinápticas que interrumpen los impulsos que se distribuyen en el miembro superior, siendo por tanto más selectivos y con menores efectos adversos para el paciente.Background: Raynaud's phenomenon, a vascular disorder that is common in the general population, consists of paroxysmal onset distal vasospasm in small cutaneous arteries and arterioles of extremities, usually with little systemic impact.

    Full Text Available There are many carcinogenetic elements in industry and it is for this reason that study and research concerning the effect of these materials is carried out on a national and international level. The establishment and growth of cancer are affected by different factors in two main areas:-1 The nature of the human or animal including sex, age, point and method of entry, fat metabolism, place of agglomeration of carcinogenetic material, amount of material absorbed by the body and the immunity of the body.2 The different nature of the carcinogenetic material e.g. physical, chemical quality, degree of solvency in fat and purity of impurity of the element. As the development of cancer is dependent upon so many factors, it is extremely difficult to determine whether a causative element is principle or contributory. Some materials are not carcinogenetic when they are pure but become so when they combine with other elements. All of this creates an industrial health problem in that it is almost impossible to plan an adequate prevention and safety program. The body through its system of immunity protects itself against small amounts of carcinogens but when this amount increases and reaches a certain level the body is not longer able to defend itself. ILO advises an effective protection campaign against cancer based on the Well –equipped laboratories, Well-educated personnel, the establishment of industrial hygiene within factories, the regular control of safety systems, and the implementation of industrial health principles and research programs.

    Glycosphingolipids from the ganglio-series are usually classified in four series according to the presence of 0 to 3 sialic acid residues linked to lactosylceramide. The transfer of sialic acid is catalyzed in the Golgi apparatus by specific sialyltransferases that show high specificity toward glycolipid substrates. ST8Sia I (EC 2.4.99.8, SAT-II, SIAT 8a) is the key enzyme controlling the biosynthesis of b- and c-series gangliosides. ST8Sia I is expressed at early developmental stages whereas in adult human tissues, ST8Sia I transcripts are essentially detected in brain. ST8Sia I together with b- and c-series gangliosides are also over-expressed in neuroectoderm-derived malignant tumors such as melanoma, glioblastoma, neuroblastoma and in estrogen receptor (ER) negative breast cancer, where they play a role in cell proliferation, migration, adhesion and angiogenesis. We have stably expressed ST8Sia I in MCF-7 breast cancer cells and analyzed the glycosphingolipid composition of wild type (WT) and GD3S+ clones. As shown by mass spectrometry, MCF-7 expressed a complex pattern of neutral and sialylated glycosphingolipids from globo- and ganglio-series. WT MCF-7 cells exhibited classical monosialylated gangliosides including G(M3), G(M2), and G(M1a). In parallel, the expression of ST8Sia I in MCF-7 GD3S+ clones resulted in a dramatic change in ganglioside composition, with the expression of b- and c-series gangliosides as well as unusual tetra- and pentasialylated lactosylceramide derivatives G(Q3) (II(3)Neu5Ac(4)-Gg(2)Cer) and G(P3) (II(3)Neu5Ac(5)-Gg(2)Cer). This indicates that ST8Sia I is able to act as an oligosialyltransferase in a cellular context.

    The (neo-) lacto series glycosphingolipids (nsGSLs) comprise of glycan epitopes that are present as blood group antigens, act as primary receptors for human pathogens and are also increasingly associated with malignant diseases. Beta-1, 3-N-acetyl-glucosaminyl-transferase 5 (B3GNT5) is suggested as the key glycosyltransferase for the biosynthesis of nsGSLs. In this study, we investigated the impact of CRISPR-Cas9 -mediated gene disruption of B3GNT5 (∆B3GNT5) on the expression of glycosphingolipids and N-glycoproteins by utilizing immunostaining and glycomics-based PGC-UHPLC-ESI-QTOF-MS/MS profiling. ∆B3GNT5 cells lost nsGSL expression coinciding with reduction of α2-6 sialylation on N-glycoproteins. In contrast, disruption of B4GALNT1, a glycosyltransferase for ganglio series GSLs did not affect α2-6 sialylation on N-glycoproteins. We further profiled all known α2-6 sialyltransferase-encoding genes and showed that the loss of α2-6 sialylation is due to silencing of ST6GAL1 expression in ∆B3GNT5 cells. These results demonstrate that nsGSLs are part of a complex network affecting N-glycosylation in ovarian cancer cells. PMID:28358117

  1. Current management of gastric cancer Situación actual en el tratamiento del cáncer gástrico

    Directory of Open Access Journals (Sweden)

    Antonio Viúdez-Berral

    2012-03-01

    Full Text Available Gastric cancer is a disease with high incidence and mortality in our population. The prognosis of patients with this disease is closely related to the neoplasm stage at diagnosis, including the following characteristics of the tumor: extension into the gastric wall thickness, spread to locoregional lymph nodes and the ability to generate distant metastases, as described by the TNM classification. For localized tumors characterized only by invasion of mucosa or submucosa at diagnosis, survival at 5 years is between 70 and 95% with exclusive surgical management; however, when extension into the gastric wall is higher and/or there is locoregional nodal involvement, survival decreases to 20-30% at 5 years. Currently, at high-volume centers, the extent of gastrectomy is individualized based on several parameters, which in an increasing number of cases allows a total gastrectomy with D2 lymphadenectomy and preservation of the spleen and pancreas. This improved procedure increases the chance of R0 surgery and improves the relationship between resected and affected lymph nodes, resulting in a decreased risk of the long-term locoregional recurrence. To improve these results, different therapeutic strategies combining chemotherapy or chemoradiotherapy with surgery have been tested. Previously, the Intergroup 0116 clinical trial, published in 2001, which changed clinical practice in the United States, showed that adjuvant chemoradiotherapy improved survival (from 26 to 37 months overall survival of these patients. In Europe, perioperative chemotherapy has been considered the standard treatment, since the publication of two randomized phase III trials showed an increase at 5 years survival in the group treated with chemotherapy.El cáncer gástrico es un tumor de alta incidencia y mortalidad en nuestro medio, y su pronóstico está íntimamente relacionado con la situación neoplásica al diagnóstico, que incluye su extensión en el grosor de la pared g

    Despite advances in our knowledge of esophageal cancer, 50% of patients present with incurable disease, and the overall survival after diagnosis is poor. The incidence of esophageal adenocarcinoma of the distal esophagus is rising at a rapid rate in developed countries. Recent advances in the epidemiology of esophageal cancer offer insights into preventive strategies in patients who are at risk. New developments in diagnosis may help detect the disease at an early stage. New diagnostic modalities permit more accurate staging procedures and allow appropriate selection of therapy. New studies provide more information on multimodality therapy for esophageal cancer, and new endoscopic techniques allow resection of small lesions without surgery. New stent designs provide better palliation by providing tumor ingrowth. These developments in the treatment of esophageal cancer are the focus of this review.

    2009-01-01

    Full Text Available Cancer nanotechnology is the latest trend in cancer therapy. It helps the pharmacist to formulate the product with maximum therapeutic value and minimum or negligible range side effects. Cancer is the disease in which the abnormal cells are quite similar to the normal cell with just minute functional or genetic change. Thus, it is very hard to target the abnormal cells by the conventional method of the drug delivery system. Nanotechnology is probably the only method that can be used for site-specific action without causing the side effects by killing the normal cells. This review article describes the possible way to exploit the nanotechnology to targeted drug therapy in cancer. The various methods used are: systemic delivery systems, passive targeting, active targeting, intracellular delivery, subcellular localization, and nanoparticle drugs. Different cancer detection techniques like carbon nanotubes, nanorods, and biosensors are also available. This review article gives an idea about the possible potential of nanotechnology in drug delivery, drug targeting, and the diagnosis of cancer.

    Although their sensitivity is not high, SCC, TPA and IAP are useful for esophageal cancer. The sensitivity of CEA, CA 19-9, is relatively high, especially in well-differentiated adenocarcinoma of gastric cancer with lymph node metastasis. AFP is specific to liver metastasis from gastric cancer, and CA 125 is also specific to peritoneal dissemination. CA 72-4 and NCC-ST-439 are useful markers for advanced staging. CEA, CA 19-9, is useful for colon cancer, especially for predicting preoperative staging. Half-life and doubling time of tumor markers is useful in some cases for the evaluation of operation and chemotherapy. We showed our data concerning postoperative CEA and/or CA 19-9 monitoring after operation for gastric cancer in 120 recurrent patients. Positivities of CEA and CA 19-9 for recurrence were 65.8% and 85.0%, respectively, both of which were significantly higher than the preoperative sensitivities (28.3% and 45.0%, respectively). In most patients with high levels of preoperative CEA and/or CA 19-9, these tumor markers increased again at recurrence. Recurrent diseases were detected between 5 months after detection by diagnostic imagings and 12 months before detection by diagnostic imagings (mean of 3.1+/-3.6 months before detection by diagnostic imagings) and between 10 months after detection by diagnostic imagings and 13 months before detection by diagnostic imagings (mean 2.2+/-3.9 months before detection by diagnostic imagings) by CEA and CA 19-9 monitorings, respectively. These results suggest that CEA and/or CA 19-9 monitoring after operation was useful to predict the recurrence of gastric cancer, especially in almost all the patients with high preoperative levels of these markers.

    Full Text Available Abstract In recent years many efforts of researchers and clinicians were made to improve our knowledge of cachexia syndrome. Not only cancer, but also many chronic or end-stage diseases such as AIDS, chronic obstructive pulmonary disease (COPD, rheumatoid arthritis, tuberculosis and Crohn's disease are associated with cachexia, a condition of abnormally low weight, weakness, and general bodily decline which deteriorates quality of life and reduces the prognosis of the patients who suffer from it. In the present editorial we will focus cachexia related on cancer and provide some insight into this prognosis-limiting syndrome.

    Cervix cancers declined in most developed countries in recent years, but remain, the third worldwide leading cause of cancer death in women. A precise staging, based on clinical exam, an abdominal and pelvic MRI, a possible PET-CT and a possible lymph node sampling is necessary to adapt the best therapeutic strategy. In France, the treatments of tumors of less than 4 cm without nodal involvement are often based on radiotherapy followed by surgery and, whereas tumors larger than 4 cm and involved nodes are treated with concurrent chemoradiotherapy. Based on an illustrated clinical case, indications, delineation, dosimetry and complications expected with radiotherapy are demonstrated.

    Squamous cell carcinoma of the penis represents approximately 0.5% of all cancers among men in the United States and other developed countries. Although rare, it is associated with significant disfigurement, and only half of the patients survive beyond 5 years. Proper evaluation of both the primary lesion and lymph nodes is critical, because nodal involvement is the most important factor of survival. The NCCN Clinical Practice Guidelines in Oncology for Penile Cancer provide recommendations on the diagnosis and management of this devastating disease based on evidence and expert consensus.

  1. Identifying cancer genes from cancer mutation profiles by cancer functions

    Institute of Scientific and Technical Information of China (English)

    2008-01-01

    It is of great importance to identify new cancer genes from the data of large scale genome screenings of gene mutations in cancers. Considering the alternations of some essential functions are indispensable for oncogenesis, we define them as cancer functions and select, as their approximations, a group of detailed functions in GO (Gene Ontology) highly enriched with known cancer genes. To evaluate the efficiency of using cancer functions as features to identify cancer genes, we define, in the screened genes, the known protein kinase cancer genes as gold standard positives and the other kinase genes as gold standard negatives. The results show that cancer associated functions are more efficient in identifying cancer genes than the selection pressure feature. Furthermore, combining cancer functions with the number of non-silent mutations can generate more reliable positive predictions. Finally, with precision 0.42, we suggest a list of 46 kinase genes as candidate cancer genes which are annotated to cancer functions and carry at least 3 non-silent mutations.

    Cancer constitutes an enormous burden on society in more and less economically developed countries alike. The occurrence of cancer is increasing because of the growth and aging of the population, as well as an increasing prevalence of established risk factors such as smoking, overweight, physical inactivity, and changing reproductive patterns associated with urbanization and economic development. Based on GLOBOCAN estimates, about 14.1 million new cancer cases and 8.2 million deaths occurred in 2012 worldwide. Over the years, the burden has shifted to less developed countries, which currently account for about 57% of cases and 65% of cancer deaths worldwide. Lung cancer is the leading cause of cancer death among males in both more and less developed countries, and has surpassed breast cancer as the leading cause of cancer death among females in more developed countries; breast cancer remains the leading cause of cancer death among females in less developed countries. Other leading causes of cancer death in more developed countries include colorectal cancer among males and females and prostate cancer among males. In less developed countries, liver and stomach cancer among males and cervical cancer among females are also leading causes of cancer death. Although incidence rates for all cancers combined are nearly twice as high in more developed than in less developed countries in both males and females, mortality rates are only 8% to 15% higher in more developed countries. This disparity reflects regional differences in the mix of cancers, which is affected by risk factors and detection practices, and/or the availability of treatment. Risk factors associated with the leading causes of cancer death include tobacco use (lung, colorectal, stomach, and liver cancer), overweight/obesity and physical inactivity (breast and colorectal cancer), and infection (liver, stomach, and cervical cancer). A substantial portion of cancer cases and deaths could be prevented by broadly

  17. Testicular cancer.

    Science.gov (United States)

    Peckham, M

    1988-01-01

    Testicular cancer, which predominantly occurs in young men, has become increasingly common; it is presently the most common malignancy in men aged 20-34. Despite a lack of knowledge of aetiology, empirical advances, particularly in the management of patients with advanced disease, have been dramatic. Prior to the development of effective chemotherapy in the 1970s, less than 10% of men with metastatic non-seminomatous germ cell tumours were cured; nowadays approximately 90% of patients are potentially curable. The introduction of effective chemotherapy has led to a reappraisal of surgery and radiotherapy in the management of early stage disease and the introduction of a policy of surveillance in patients without evidence of metastases at the time of removal of the primary tumour. Following chemotherapy, surgery is required in approximately 25% of patients with advanced disease to excise residual masses, which in one-fifth of cases will show evidence of residual malignancy. In a proportion of patients, testicular cancer develops on a background of long-standing infertility, whereas in many men there is temporary oligospermia, despite a previous history of fertility. The majority of patients with prior evidence of spermatogenesis recover this function following chemotherapy and there is no evidence that children fathered by such patients have an increased risk of malformation. Despite physician optimism and excellent prospects for cure, significant psycho-social morbidity is associated with the diagnosis and treatment of testicular cancer. Factors contributing to this are being identified and will lead, hopefully, to the minimisation of such problems by appropriate intervention.

    Gastric cancer represents a disorder which incidence has come down last years. Its etiology is unknown, but diet is the principal determinant risk of suffering it. Clinic history is not much useful, because in the early stage symptoms can fail and in the late stage are inespecific. Election diagnosis is endoscopy. Surgery is the only curative treatment. By these features, it would be useful to left under vigilance to: a) patients 40 years older with dispepsia; b) patients following gastric operations; c) patients with disorders presenting aclorhidria. The authors report a clinic case that can be of frequent presentation in primary assistance.

    Telomeres are a double-edged sword when it comes to cancer. On one hand, telomeres limit the cells' ability to divide and thereby restrict the uninhibited growth seen in cancer. On the other hand, short telomeres can initiate the chromosome instability that characterizes cancer. Diseases...... with the combination of short telomeres and high cancer risk are seen, but until now the use of telomeres as predictors of cancer has, in general, been unsuccessful. Telomeres and telomerase play an important role in further cancer development. Researchers are trying to exploit this in the development of new cancer...

    Solomon, Sheila; Das, Siddhartha; Brand, Randall; Whitcomb, David C

    2012-01-01

    Pancreatic cancer remains one of the most challenging of all cancers. Genetic risk factors are believed to play a major role, but other than genes coding for blood group, genetic risks for sporadic cases remain elusive. However, several germline mutations have been identified that lead to hereditary pancreatic cancer, familial pancreatic cancer, and increased risk for pancreatic cancer as part of a familial cancer syndrome. The most important genes with variants increasing risk for pancreatic cancer include BRCA1, BRCA2, PALB2, ATM, CDKN2A, APC, MLH1, MSH2, MSH6, PMS2, PRSS1, and STK11. Recognition of members of high-risk families is important for understanding pancreatic cancer biology, for recommending risk reduction strategies and, in some cases, initiating cancer surveillance programs. Because the best methods for surveillance have not been established, the recommendation to refer at-risk patients to centers with ongoing research programs in pancreatic cancer surveillance is supported.

    2010-12-01

    Breast cancer is the most common cancer in women, and the second most common cause of cancer death after lung cancer. Improvements in the outcome of breast cancer mean that more patients are living longer and are, therefore, at risk of developing a second malignancy. The aim of this review is to present the current understanding of the risk of lung cancer arising in patients previously treated for early stage breast cancer. We review data on the effect of treatment factors (ie, surgery type, radiotherapy technique, and adjuvant chemotherapy) and patient factors (ie, age and smoking) on the risk of developing a subsequent lung cancer. The evidence suggests that older radiotherapy techniques were associated with a substantially increased risk of developing lung cancer in the ipsilateral lung, but there is no clear evidence of an increased risk with modern techniques. Smoking is an important risk factor, and increases the risk of lung cancer in those receiving radiotherapy. Adjuvant chemotherapy is not significantly associated with an increased risk. The risk of developing lung cancer increases with time elapsed since treatment, but any effect of age at treatment is unclear.

    Compelling evidence supports a genetic component to prostate cancer susceptibility and aggressiveness. Recent genome-wide association studies have identified more than 30 single-nucleotide polymorphisms associated with prostate cancer susceptibility. It remains unclear, however, whether such genetic variants are associated with disease aggressiveness--one of the most important questions in prostate cancer research today. To help clarify this and substantially expand research in the genetic determinants of prostate cancer aggressiveness, the first National Cancer Institute Prostate Cancer Genetics Workshop assembled researchers to develop plans for a large new research consortium and patient cohort. The workshop reviewed the prior work in this area and addressed the practical issues in planning future studies. With new DNA sequencing technology, the potential application of sequencing information to patient care is emerging. The workshop, therefore, included state-of-the-art presentations by experts on new genotyping technologies, including sequencing and associated bioinformatics issues, which are just beginning to be applied to cancer genetics.

    Full Text Available Objective: To assess the association between physiological, physical, lifestyle and nutritional variables and oxidative stress biomarkers in women with breast cancer. Methods: This cross-sectional study was conducted on 55 women newly diagnosed with breast cancer. The extent of oxidative stress was analyzed by the measurement of plasma lipid hydroperoxides (LH, thiobarbituric acid reactive substances (TBARS, protein carbonyl, whole blood reduced glutathione (GSH and serum antioxidant capacity (AC. Diet data were obtained from food frequency questionnaire. Linear regression was used to determine the association between the variables studied and oxidative stress biomarkers. The protein carbonyl data was not included in the linear regression analyses since the data did not show a normal distribution, even after logarithmic and other transformations. Results: After adjusting for energy intake, the intake of chicken and high-fat dairy products was associated with increased levels of LH, while vitamin E intake was associated with decreased LH levels (R² = 23.8%. Intake of oils was associated with increased levels of TBARS (R² = 6.82%. Positive axillary lymph node status was associated with decreased levels of GSH (R² = 9.31%. Increasing age was directly associated with levels of AC, while animal fat, dairy product, and sweet food intakes were associated with low levels of AC (R² = 41.42%. Conclusion: Intake of chicken, vitamin E, dairy products (particularly high-fat dairy products, oils, animal fat, and sweet foods, along with axillary lymph node status and age, may be important determinants of oxidative stress in women with breast cancer.Objetivo: Evaluar la asociación entre las variables fisiológicas, físicas, de estilo de vida y nutricionales y de los biomarcadores de estrés oxidativo en mujeres con cáncer de mama.

    The primary cause of death in women in the world is cancer. In most developing countries cancer of the cervix is the most prevalent cancer. Breast cancer has this distinction in Latin America and the developed countries of North America, Europe, Australia, and New Zealand. It is also the most prevalent cancer worldwide. The most common cancer in Japan and the Soviet Union is stomach cancer. Effective early detection programs can reduce both breast and cervical cancer mortality and also the degree and duration of treatment required. In Iceland, cervical cancer mortality declined 60% between the periods of 1959-1970 and 1975-1978. Programs consist of mammography, physician breast and self examination, and Pap smear. The sophisticated early detection equipment and techniques are expensive and largely located in urban areas, however, and not accessible to urban poor women and rural women, especially in developing countries. Tobacco smoking attributes to 80-90% of all lung cancer deaths worldwide and 30% of all cancer deaths. Passive smoking increases the risk of lung cancer to 25-35% in nonsmokers who breathe in tobacco smoke. Since smoking rates of women are skyrocketing, health specialists fear that lung cancer will replace cervical and breast cancers as the most common cancer in women worldwide in 20-30 years. Tobacco use also contributes to the high incidence of oral cancer in Southern and South Eastern Asia. For example, in India, incidence of oral cancer in women is 3-7 times higher than in developed countries with the smoking and chewing of tobacco in betel quid contributing. Techniques already exist to prevent 1/3 of all cancers. If cases can be discovered early enough and adequate treatment applied, another 1/3 of the cases can be cured. In those cases where the cancer cannot be cured, drugs can relieve 80-90% of the pain.

    2016-07-01

    Treatment of lung cancer remains a challenge, and lung cancer is still the leading cause of cancer-related mortality. Immunotherapy has previously failed in lung cancer but has recently emerged as a very effective new therapy, and there is now growing worldwide enthusiasm in cancer immunotherapy. We summarize why immune checkpoint blockade therapies have generated efficacious and durable responses in clinical trials and why this has reignited interest in this field. Cancer vaccines have also been explored in the past with marginal success. Identification of optimal candidate neoantigens may improve cancer vaccine efficacy and may pave the way to personalized immunotherapy, alone or in combination with other immunotherapy such as immune checkpoint blockade. Understanding the steps in immune recognition and eradication of cancer cells is vital to understanding why previous immunotherapies failed and how current therapies can be used optimally. We hold an optimistic view for the future prospect in lung cancer immunotherapy.

    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.

En consecuencia, se realizan de forma rutinaria múltiples estudios para determinar el compromiso local, regional y a distancia. Adicionalmente, en los ganglios cervicales existe el riesgo de metástasis microscópicas, dependiente del tamaño y del nivel de invasión tumoral; por lo que rutinariamente se realizan disecciones profilácticas de cuello, incluso en estadios tempranos, existiendo siempre la probabilidad de complicación y morbilidad asociada. Por lo tanto, en la última década se aceptó el uso del ganglio centinela con la intención de disminuir dicha probabilidad, incluso para tumores tempranos de la cavidad oral. Además, en los últimos años se ha planteado la cirugía de rescate de metástasis ganglionares del cuello en recaída o persistencia después de tratamientos con quimioterapia y/o radioterapia, mediante disecciones superselectivas de cuello (DSSC.

    The recurrence of a cancer - local or distant (metastasis) - is manifested by the persistence of cancer cells in the organism after the ablation of the primary lesion, an ineffective anticancer immune response, and by the activity of biological/immunological factors that can stimulate and sustain its development. This review focuses on colorectal carcinoma and discusses some aspects of cancer immunology regarding cancer development and its recurrence. It is addressed also to the clinician to provide new insights helpful for designing better therapeutic strategies and patient's follow up. Therapeutic approaches used during and after surgical treatments, found capable of modulating immunity (differently affecting disease outcome), will also be described.

    Initiated by IKNL (Integraal Kankercentrum Nederland), a multidisciplinary guideline for cancer rehabilitation for adult oncology patients has been developed. The guideline describes the rehabilitation care of adult patients with cancer, during and after treatment. The guideline focuses on (a) prevalence of complaints either resulting from cancer or the treatment, (b) detection of these complaints and indicated referral, (c) the intake procedure before cancer rehabilitation, (d) intervention and evaluation within cancer rehabilitation and (e) the importance of patient empowerment. The guideline is directed at all professionals giving care to patients with cancer. It concerns those (such as medical specialists, general practitioners and nurses) who are responsible for detecting cancer-related complaints and for referral to cancer rehabilitation, as well as health care professionals involved in cancer rehabilitation care (such as consultants in rehabilitation medicine, physiotherapists and psychologists). The main goal of the guideline is that every cancer patient or ex-cancer patient with (residual) complaints resulting from cancer or its treatment receives timely and appropriate cancer rehabilitation.

    In 2007 the World Cancer Research Fund and American Institute for Cancer Research (WCRF/AICR) report judged that the evidence for an association between red and processed meat consumption and colorectal cancer was convincing. In addition, the effect of other animal products on cancer risk has been studied, and the WCRF/AICR report concluded that milk probably decreases the risk of colorectal cancer but diets high in calcium probably increase the risk of prostate cancer, whereas there was limited evidence for an association between milk and bladder cancer and insufficient evidence for other cancers. There are several potential mechanisms relating meat to cancer, including heterocyclic amines, polycyclic aromatic hydrocarbons, N-nitroso compounds, and heme iron. Although the evidence in favor of a link between red and processed meat and colorectal cancer is convincing, the relations with other cancers are unclear. In this review, we summarize cohort studies conducted by the National Cancer Institute on meat and dairy intake in relation to cancer since the 2007 WCRF/AICR report. We also report the findings of meta-analyses published since 2007.

    antecedentes: el cáncer de mama en el hombre es una enfermedad con baja incidencia, que se reduce aún más cuando es bilateral sincrónica. Existen pocas publicaciones en los últimos años. Objetivo: establecer pautas para el tratamiento de este cáncer, aunque sea infrecuente. Caso clínico: paciente masculino de 75 años de edad, con tumores en ambas mamas, que se le resecaron completamente con exéresis de ganglios palpables. El estudio histopatológico informó que se trataba de un carcinoma ductal infiltrante no especificado. Se indicó tratamiento adyuvante con tamoxifeno y radioterapia; en la actualidad está libre de enfermedad. Conclusiones: el carcinoma mamario bilateral sincrónico en el varón es una enfermedad poco frecuente. Su tratamiento principal es la cirugía, de ahí la importancia del diagnóstico temprano. En la mayoría de los casos se requiere quimioterapia y radioterapia adyuvante porque suelen diagnosticarse en un estadio avanzado.

    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. Cellular & Molecular Immunology.

    Directory of Open Access Journals (Sweden)

    1987-04-01

    Full Text Available Farly detection of cancer is based upon three fundamental assumptions, firstly that the trea'ment of benign and precancerous lesions reduces the incidence of cancer, secondly, that the treatment of in situ cancers is conducive to total cure and thirdly that early diagnosis and management of invasive cancer ensures be.ter survival. When patient seeks medical advice for vague symptoms, which could however be due to a possible malignant tumour at a particular site, the alert clinician should investigate the patient immediately to exclude cancer. At this stage cancer is usually not significantly advanced.Currently the U. I. C. C. (International Union for Cancer Control} is studying the epidemiology of cancers in various countries The importance of this is two folds : Firstly by focussing attention on a section of population vulnerable to a particular cancer an early detection is facilitated Secondly by changing the causative factors responsible to a particular cancer, the incidence of that cancer can be reduced e. g. reduction in lung cancer following campaigns against ciguette smoking and reductioi in breast cancer after campaigns for advocating breast feeding of infants, lowering fat consumption and encouraging self palpation of breast regularly.Indeed early diagnosis of cancer implies diagnosis of cancer in almost a symptomatic stage It involves motiva’ion of the population towards acquisitio : of knowledge, attitude and practice.. Epidemiologies and clinicians should be able to recognise high risk cases exposed to particular neoplasia and knowledge of alarming symptoms should be pro- pogated for wide publicity through common available media and means. Probable cases should have regular clhrcal examination periodically and relevant investigations including radiological, imaging techniques and Bio-Chemical examination should be undertaken as and when desired Suspicious lesions should be investigated by specific tests including smear cytology

  8. Basics of cancer immunotherapy.

    Science.gov (United States)

    Fujioka, Yuki; Nishikawa, Hiroyoshi

    The immune system is the body's defense against infectious organisms and other invaders including cancer cells. Cancer immunotherapy, which employs our own immune systems to attack cancer cells, is now emerging as a promising modality of cancer treatment based upon the clinical successes of immune checkpoint blockade and adoptive T cell transfer. In hematologic malignancies, clinical application of anti-PD-1 mAb and CAR (chimeric antigen receptor) T therapy is now being extensively tested in Hodgkin's disease, multiple myeloma, and CD19(+) acute lymphocytic leukemia. In sharp contrast to conventional anti-cancer reagents which directly kill cancer cells, cancer immunotherapy activates various types of immune effector cells to attack cancer cells. However, more than half of the treated patients showed no activation of anti-tumor CD8(+) killer T cells and CD4(+) helper T cells and failed to respond to immune therapies such as immune checkpoint blockade, even when administered in combination regimens. Thus, development of novel immunotherapies to achieve more effective activation of anti-cancer immunity and immuno-monitoring of biomarkers, allowing proper evaluation of immune responses in cancer patients in order to detect responders, are urgent issues. Additionally, we must pay attention to characteristic immunological side effects not observed following treatment with conventional anti-cancer reagents. Herein, we present a summary outline and discuss the future direction of cancer immunotherapy.

    Cancer is predicted to be an increasingly important cause of morbidity and mortality in Bangladesh in the next few decades. The estimated incidence of 12.7 million new cancer cases will rise to 21.4 million by 2030. More than two-thirds of the total expenditure on health is through out-of-pocket payments. According to the Bangladesh Bureau of Statistics, cancer is the sixth leading cause of death. International Agency for Research on Cancer has estimated cancer-related death rates in Bangladesh to be 7.5% in 2005 and 13% in 2030. The two leading causes are in males are lung and oral cancer and in females are breast cancer and cervical cancer. Bangladesh is now in severe shortage of radiation therapy machines, hospital bed, trained oncologists, medical radiation physicists and technologists. Bangladesh having different cancers associated with smoking and smokeless tobacco use, Human papilloma virus infection, Hepatitis B and C infection, Helicobacter Pylori infection, arsenic contaminated groundwater, availability of chemical carcinogens mainly formalin treated fruits, fish and vegetables at open market, tannery waste contaminated with chromium (which is used for poultry feed and fish feed preparation). A World Health Organization study revealed the annual cost of illnesses in Bangladesh attributable to tobacco usage is US$ 500 million and the total annual benefit from the tobacco sector is US$ 305 million as tax revenue. Bangladesh has developed a National Cancer Control Strategy and Action Plan with the aim of delivering a universal, quality-based and timely service. Cancer prevention through tobacco control, health promotion and vaccination program, cancer early detection program for oral cavity, breast and cervix has initiated. Cancer detection and diagnostic facilities will be made available at medical colleges and district- hospitals and establish a referral chain. National capacity development, more cancer research will allow Bangladesh to deal effectively

Hubo recurrencia de la enfermedad en el 19%. Los pacientes con tumores de hasta 15 mm tuvieron una supervivencia a los 5 años de 95% (IC: 0.05 y con más de 15 mm, de 77%. (IC: 0.07, siendo la diferencia estadísticamente significativa (log-rank test: 0.035. La supervivencia libre de enfermedad fue de 95% en los tumores de hasta 15 mm y de 72% (IC: 0.09 en los de más de 15 mm. El análisis multivariado (Cox mostró que el mayor determinante del riesgo de mortalidad fue el tamaño mayor de 15 mm (riesgo relativo 25.9, IC: 2.3-292, p = 0.004. Este estudio demuestra la influencia del tamaño del tumor en estadio IA, lo cual puede tener importancia práctica en función de las recientes propuestas de investigación sistemática de pacientes con alto riesgo de cáncer pulmonar.TNM staging is an important long-term predictor for survival of lung cancer patients. Some studies have shown, however, that tumor size may have intrinsic prognostic value independent of TNM stage. The relationship between tumor size and survival is particularly unclear in T1 tumors. The objective of this study was to assess the prognostic value of tumor size in surgically resected stage I of non-small cell lung cancer

    Pancreatic cancer is molecularly diverse, with few effective therapies. Increased mutation burden and defective DNA repair are associated with response to immune checkpoint inhibitors in several other cancer types. We interrogated 385 pancreatic cancer genomes to define hypermutation and its causes. Mutational signatures inferring defects in DNA repair were enriched in those with the highest mutation burdens. Mismatch repair deficiency was identified in 1% of tumors harboring different mechanisms of somatic inactivation of MLH1 and MSH2. Defining mutation load in individual pancreatic cancers and the optimal assay for patient selection may inform clinical trial design for immunotherapy in pancreatic cancer.

    Cervical cancer is one of the leading causes of cancer and cancer-related deaths among women worldwide. More than 85% of cases and deaths occur in the developing world where the availability of effective screening is limited. In this issue of the journal, Pierce and colleagues (beginning on page 1273) describe a novel technique using a high-resolution microendoscope (HRME) to diagnose cervical dysplasia. This perspective reviews the limitations of existing cervical cancer screening methods currently in use in low-resource settings and the potential for HRME imaging to contribute to cervical cancer prevention in the developing world.

    Epidemiologic evidence on the relationship between selected industries and cancer is reviewed. This article will focus on several industries which have not been covered elsewhere in this volume, briefly describe current research on cancer in the agricultural and construction industries, and discuss surveillance data on cancer mortality in relation to industry listed on US death certificates. Employment in the rubber industry has been associated with bladder cancer, leukemia, stomach, and lung cancer and is considered by the International Agency for Research on Cancer (IARC) to have 'sufficient evidence of carcinogenicity in humans.' Studies of workers exposed to polychlorinated biphenyls (PCBs) have reported excess mortality from gastrointestinal neoplasms, hematologic neoplasms, and skin cancer (specifically malignant melanoma); IARC considers that the evidence for carcinogenicity in humans is 'limited.' Employment in the boot and shoe industry has been associated with nasal adenocarcinomas in England and Italy ('sufficient'). Hairdressers and barbers have been found to have excess bladder cancer and less consistent evidence for several other sites ('limited'). Workers exposed to wood dust have excess mortality from cancer of the nasal sinuses and paranasal cavities; there is less consistent evidence for excess laryngeal cancer ('sufficient'). Workers employed in the petroleum industry have limited evidence for excess leukemia and other lymphatic and hematopoietic neoplasms, and skin cancer (particularly malignant melanoma) ('limited').

    Full Text Available Life style factors are contributing significantly in cancer prevention. With the intake of proper and balanced diet ,cancer prevention is possible. Many foods are associated either with incidence or prevention of cancer. Plant based foods like fresh fruits, vegetables and whole grains rich in fiber, b-carotene, vitamins and antioxidants can prevent cancer. Fiber rich foods increase bowel movement, decreasing the absorption of cholesterol. Pumpkin, carrots contain b-carotenes. Leafy vegetables, broccoli, cabbage, cauliflower, peas and beans are rich in fiber and stimulate cancer preventing enzyme induction. Vitamin C rich citrus fruits can stimulate immune system. Garlic and onions can stimulate enzymes that can suppress tumor growth. Turmeric used in cooking can prevent colorectal cancer. Topical application of turmeric can prevent breast cancer in women. On the other hand, certain foods can cause cancer. Refined foods, high fat foods, deep fried foods, processed foods and low fiber foods increase cancer risk. Red meat, processed meat and barbeques contain a carcinogen called acrylamide. Foods prepared with hydrogenated fats contain transfats which increase risk for breast, ovarian, cervical and lung cancer. Consumption of alcohol increasing the risk for cancers of digestive system.

    The diagnosis of cancer can be shattering to all involved. The treatment of cancer is intense and often very challenging. Prevailing attitudes to cancer are sometimes fearful, negative and depressing. This combination may leave those affected by cancer shocked, disorientated and without hope. Even worse than this, on asking consultants 'What can I do to help myself?' patients are frequently told 'Absolutely nothing'--crushing in one fell swoop their remaining fighting spirit. Not so in the case of Penny Brohn, who, when faced with the diagnosis of breast cancer, travelled the world to find alternative cancer treatments, and having successfully brought her own cancer under control, dedicated her life to creating a Centre for others wishing to fight their disease.

    The current prevalence of thyroid cancer in women is high. Likewise, other cancers and thyroid cancer have been based on the TNM classification system. Staging of thyroid cancer has an important role in determining the extent of surgical excision and lymph node dissection, planning the adjuvant therapy after surgery and predicting the recurrence rate and the prognosis of patients. Ultrasonography is the basic imaging modality to identify the tumor size and the extent of lymph node metastasis. More recently, computed tomography, magnetic resonance imaging and positron emission tomography provide additional help for the staging of thyroid cancer. So, this article describes the 7th edition of the TNM staging of thyroid cancer, as proposed by the American Joint Committee on Cancer, and the details of radiologic evaluation of the T, N and M stages

    Full Text Available Lung cancer remains a major cause of cancer-related lethality because of high incidence and recurrence in spite of significant advances in staging and therapies. Recent data indicates that stem cells situated throughout the airways may initiate cancer formation. These putative stem cells maintain protumorigenic characteristics including high proliferative capacity, multipotent differentiation, drug resistance and long lifespan relative to other cells. Stem cell signaling and differentiation pathways are maintained within distinct cancer types, and destabilization of this machinery may participate in maintenance of cancer stem cells. Characterization of lung cancer stem cells is an area of active research and is critical for developing novel therapies. This review summarizes the current knowledge on stem cell signaling pathways and cell markers used to identify the lung cancer stem cells.

    Cancer is driven by the somatic evolution of cell lineages that have escaped controls on replication and by the population-level evolution of genes that influence cancer risk. We describe here how recent evolutionary ecological studies have elucidated the roles of predation by the immune system and competition among normal and cancerous cells in the somatic evolution of cancer. Recent analyses of the evolution of cancer at the population level show how rapid changes in human environments have augmented cancer risk, how strong selection has frequently led to increased cancer risk as a byproduct, and how anticancer selection has led to tumor-suppression systems, tissue designs that slow somatic evolution, constraints on morphological evolution and even senescence itself. We discuss how applications of the tools of ecology and evolutionary biology are poised to revolutionize our understanding and treatment of this disease.

    Cancer stem cells (CSCs) are thought to be responsible for tumor initiation, drug and radiation resistance, invasive growth, metastasis, and tumor relapse, which are the main causes of cancer-related deaths. Gastrointestinal cancers are the most common malignancies and still the most frequent cause of cancer-related mortality worldwide. Because gastrointestinal CSCs are also thought to be resistant to conventional therapies, an effective and novel cancer treatment is imperative. The first reported CSCs in a gastrointestinal tumor were found in colorectal cancer in 2007. Subsequently, CSCs were reported in other gastrointestinal cancers, such as esophagus, stomach, liver, and pancreas. Specific phenotypes could be used to distinguish CSCs from non-CSCs. For example, gastrointestinal CSCs express unique surface markers, exist in a side-population fraction, show high aldehyde dehydrogenase-1 activity, form tumorspheres when cultured in non-adherent conditions, and demonstrate high tumorigenic potential in immunocompromised mice. The signal transduction pathways in gastrointestinal CSCs are similar to those involved in normal embryonic development. Moreover, CSCs are modified by the aberrant expression of several microRNAs. Thus, it is very difficult to target gastrointestinal CSCs. This review focuses on the current research on gastrointestinal CSCs and future strategies to abolish the gastrointestinal CSC phenotype.

    Gastric cancer is the second most common of cancer-related deaths worldwide. In the majority of cases gastric cancer is advanced at diagnosis and although medical and surgical treatments have improved, survival rates remain poor. Cancer immunotherapy has emerged as a powerful and promising clinical approach for treatment of cancer and has shown major success in breast cancer, prostate cancer and melanoma. Here, we provide an overview of concepts of modern cancer immunotherapy including the theory, current approaches, remaining hurdles to be overcome, and the future prospect of cancer immunotherapy in the treatment of gastric cancer. Adaptive cell therapies, cancer vaccines, gene therapies, monoclonal antibody therapies have all been used with some initial successes in gastric cancer. However, to date the results in gastric cancer have been disappointing as current approaches often do not stimulate immunity efficiently allowing tumors continue to grow despite the presence of a measurable immune response. Here, we discuss the identification of targets for immunotherapy and the role of biomarkers in prospectively identifying appropriate subjects or immunotherapy. We also discuss the molecular mechanisms by which tumor cells escape host immunosurveillance and produce an immunosuppressive tumor microenvironment. We show how advances have provided tools for overcoming the mechanisms of immunosuppression including the use of monoclonal antibodies to block negative regulators normally expressed on the surface of T cells which limit activation and proliferation of cytotoxic T cells. Immunotherapy has greatly improved and is becoming an important factor in such fields as medical care and welfare for human being. Progress has been rapid ensuring that the future of immunotherapy for gastric cancer is bright.

    Pancreatic cancer is the fourth leading cause of cancer death in both men and women in the United States and will be responsible for an estimated 28,900 deaths in 2001. Relatively little is known of its etiology, and the only well-established risk factor is cigarette smoking. Studies over the past 3 decades have shown that 4%-16% of patients with pancreatic cancer have a family history of the disease. A small fraction of this aggregation can be accounted for in inherited cancer syndromes, including familial atypical multiple-mole melanoma, Peutz-Jeghers syndrome, hereditary breast-ovarian cancer, hereditary pancreatitis, and hereditary nonpolyposis colorectal cancer. These syndromes arise as a result of germline mutations in the BRCA2, pl6 (familial atypical multiple-mole melanoma), mismatch repair (hereditary nonpolyposis colorectal cancer), and STK11 (Peutz-Jeghers syndrome) genes. In addition, hereditary plays a role in predisposing certain patients with apparently sporadic pancreatic cancer. Many patients with pancreatic cancers caused by a germline mutation in a cancer-causing gene do not have a pedigree that is suggestive of a familial cancer syndrome. A recent prospective analysis of the pedigrees in the National Familial Pancreatic Tumor Registry found that individuals with a family history of pancreatic cancer in multiple first-degree relatives have a high risk of pancreatic cancer themselves. The identification of such high-risk individuals will help clinicians target screening programs and develop preventive interventions with the hope of reducing the mortality of pancreatic cancer in these families.

    Full Text Available Evidence from both animal and epidemiologic studies indicate that throughout life excessive energy intake in relation to requirements increases risk of human cancer. Rapid growth rates in childhood lead to earlier age at menarche, which in turn increases risk of breast cancer, and accumulation of body fat in adulthood in related to cancers of the colon, kidney, and endometrium as well as postmenopausal breast cancer. Higher intake of vegetables and fruits has been associated with lower risks of many cancers. The constituents responsible for these apparent protective effects remain uncertain, although evidence supports a contribution of folic acid. Recent evidence suggests that the percentage of energy from fat in the diet is not a major cause of cancers of the breast or colon. Higher intake of meat and dairy products has been associated with greater risk of prostate cancer, which may be related to their saturated fat content. Also, red meat consumption has been associated with risk of colon cancer in numerous studies, but this appears to be unrelated to its fat content. Excessive consumption of alcohol increases risks of upper gastrointestinal tract and even moderate intake appears to increase cancers of the breast and large bowel. Although many details remain to be learned, evidence is strong that remaining physically active and lean throughout life, consuming an abundance of fruits and vegetables, and avoiding high intakes of red meat, foods high in animal fat, and excessive alcohol will substantially reduce risk of human cancer.

    The incidence and mortality of gastric cancer have fallen dramatically in US and elsewhere over the past several decades. Nonetheless, gastric cancer remains a major public health issue as the fourth most common cancer and the second leading cause of cancer death worldwide. Demographic trends differ by tumor location and histology. While there has been a marked decline in distal, intestinal type gastric cancers, the incidence of proximal, diffuse type adenocarcinomas of the gastric cardia has been increasing, particularly in the Western countries. Incidence by tumor sub-site also varies widely based on geographic location, race, and socioeconomic status. Distal gastric cancer predominates in developing countries, among blacks, and in lower socioeconomic groups, whereas proximal tumors are more common in developed countries, among whites, and in higher socio-economic classes. Diverging trends in the incidence of gastric cancer by tumor location suggest that they may represent two diseases with different etiologies. The main risk factors for distal gastric cancer include Helicobacter pylori (H pylori) infection and dietary factors, whereas gastroesophageal reflux disease and obesity play important roles in the development of proximal stomach cancer. The purpose of this review is to examine the epidemiology and risk factors of gastric cancer, and to discuss strategies for primary prevention.

    In many developed countries, notification of cancer cases is compulsory. Developing countries including India accounts for more than half of new cancer cases in the world, however notification of cancer is not yet mandatory. The primary purpose of notification is to effect prevention and control and better utilization of resources. It is also a valuable source for incidence, prevalence, mortality and morbidity of the disease. Notification of cancer will lead to improved awareness of common etiologic agents, better understanding of common preventable causes and better utilization of health resources with better monitoring and evaluation of the effectiveness of health programs such as cancer screening and cancer treatment programs, which ultimately might improve survival. Notification of cancer can be done by the doctor or the hospital. Akin to the integrated disease surveillance project where more than 90% of the districts report weekly data through E-mail/portal, notification of cancer can be implemented if it is incorporated into the National Program for Prevention and Control of Cancer, Diabetes, Cardiovascular diseases and Stroke scheme.

    Background Cancer pain is a devastating condition. Pain in the orofacial region, may be present as the single symptom of cancer or as a symptom of cancer in its later stages. This manuscript revises in a comprehensive manner the content of the conference entitled “Orofacial Pain and Cancer” (Dolor Orofacial y Cancer) given at the VI Simposio International “Advances in Oral Cancer” on the 22 July, 2016 in Donostia. Material and Methods We have reviewed (pubmed-medline) from the most relevant literature including reviews, systematic reviews and clinical cases, the significant and evidence-based mechanisms and mediators of cancer-associated facial pain, the diverse types of cancers that can be present in the craniofacial region locally or from distant sites that can refer to the orofacial region, cancer therapy that may induce pain in the orofacial region as well as discussed some of the new advancements in cancer pain therapy. Results There is still a lack of understanding of cancer pain pathophysiology since depends of the intrinsic heterogeneity, type and anatomic location that the cancer may present, making more challenging the creation of better therapeutic options. Orofacial pain can arise from regional or distant tumor effects or as a consequence of cancer therapy. Conclusions The clinician needs to be aware that the pain may present the characteristics of any other orofacial pain disorder so a careful differential diagnosis needs to be given. Cancer pain diagnosis is made by exclusion and only can be reached after a thorough medical history, and all the common etiologies have been carefully investigated and ruled out. The current management tools are not optimal but there is hope for new, safer and effective therapies coming in the next years. Key words:Pain, orofacial, facial, cancer. PMID:27694791

    Although only a relatively small proportion of cancer is attributable to occupational exposure to carcinogenic agents, the estimated number of deaths due to occupational cancer is high when compared to other deaths due to work-related ill health and injury. However, risk from occupational exposure to carcinogens can be minimised through proportionate but effective risk management. The Health and Safety Executive (HSE) is the regulator of workplace health and safety in Great Britain. As part of its aim to reduce ill health arising from failures to control properly exposure to hazards at work, HSE commissioned the research presented elsewhere in this supplement to enable it to identify priorities for preventing occupational cancer. The research has shown that occupational cancer remains a key health issue and that low-level exposure of a large number of workers to carcinogens is important. The finding that a small number of carcinogens have been responsible for the majority of the burden of occupational cancer provides key evidence in the development of priorities for significant reduction of occupational cancer. Although the research presented in this supplement reflects the consequences of past exposures to carcinogens, occupational cancer remains a problem. The potential for exposure to the agents considered in this research is still present in the workplace and the findings are relevant to prevention of future disease. In this article, the principle approaches for risk reduction are described. It provides supporting information on some of the initiatives already being undertaken, or those being put in place, to reduce occupational cancer in Great Britain. The need also for systematic collection of exposure information and the importance of raising awareness and changing behaviours are discussed.

Indonesia is an Archipelago with a total area of 1,922,570.00 km(2), the population is 222,192,000 (2006), the fourth world rank. Female is 49.86% with life expectancy 69 years. Gross National Product per Capita is 690.00 USD. Histopathological report in 2002 revealed that cervical cancer, ovarian cancer and uterine cancer were the most frequent cancer among female, which were the first (2,532 cases), the third (829 cases) and the eighth (316 cases) rank respectively. The peak age for cervical, uterine and ovarian cancer was 45-54 years. HPV 16, 18 were found in 82% of invasive cervical. Data from various academic hospitals in 2007 showed that cervical cancer is the most common malignancy followed by ovary, uterus, vulva and vagina. Five-year survival rate of stage I, II, III, IV cervical cancer were 50%, 40%, 20%, and 0% respectively. Overall five-year survival rate of carcinoma of the ovary was 54.8%. If sub-classified by stage, five-year survival rate are 94.3%, 75.0%, 31%, and 11.7% for stage I, II, III, and IV respectively. Five-year disease-free survival rate of endometrial cancer was 71.9%. Indonesia is the biggest Archipelago with a dense population but the income per capita still low (poor country). The most common gynecologic cancer is cervical cancer, followed by ovarian and uterine cancer. These cancers are included in top ten cancers in Indonesia. HPV 16, 18 were the most cause of cervical cancer. The five-year survival rates are comparable with world report.

  4. Advances in cancer immunology and cancer immunotherapy.

    2016-02-01

    After decades of setbacks, cancer immunology is living its Golden Age. Recent advances in cancer immunology have provided new therapeutic approaches to treat cancer. The objective clinical response observed in patients treated with antibodies that block the immune checkpoints, cytotoxic T-lymphocyte-associated protein 4 (CTLA-4) and programmed cell-death protein 1 (PD-1)/programmed cell-death 1 ligand 1 (PD-L1) pathways, has led to their FDA approval for the treatment of melanoma in 2011 and in 2014, respectively. The anti-PD-1 antibody nivolumab has received the FDA-approval in March 2015 for squamous lung cancer treatment. In addition, antibodies targeting PD-1 or PD-L1 have demonstrated their efficacy and safety in additional tumors, including non-small cell lung carcinoma (NSCLC), renal cell carcinoma (RCC), bladder cancer, and Hodgkin's lymphoma. Almost at the same time, the field of adoptive cell transfer has exploded. The chimeric antigen receptor (CAR) T technology has provided strong evidence of efficacy in the treatment of B cell malignancies, and different T cell based treatments are currently under investigation for different types of tumors. In this review we will discuss the latest advances in cancer immunology and immunotherapy as well as new treatments now under development in the clinic and potential strategies that have shown promising results in preclinical models.

    Survival for patients with advanced oesophageal and stomach cancer is poor; together these cancers are responsible for more than a million deaths per year globally. As chemotherapy and targeted therapies such as trastuzumab and ramucirumab result in modest improvements in survival but not long-term cure for such patients, development of alternative treatment approaches is warranted. Novel immunotherapy drugs such as checkpoint inhibitors have been paradigm changing in melanoma, non-small cell lung cancer and urothelial cancers. In this review, we assess the early evidence for efficacy of immunotherapy in patients with gastroesophageal cancer in addition to considering biomarkers associated with response to these treatments. Early results of Anti- Programmed Cell Death Protein-1 (anti-PD-1), anti-PD-L1 and anti-Cytotoxic T-lymphocyte assosciated protein-4 (anti-CTLA4) trials are examined, and we conclude with a discussion on the future direction for immunotherapy for gastroesophageal cancer patients.

    Prostate cancer is the most common malignancy among males worldwide, and is the second leading cause of cancer death among men in United States. According to GLOBOCAN (2012), an estimated 1.1 million new cases and 307,000 deaths were reported in 2012. The reasons for the increase of this disease are not known, but increasing life expectancy and modified diagnostic techniques have been suggested as causes. The established risk factors for this disease are advancing age, race, positive family history of prostate cancer and western diet (use of fat items). Several other risk factors, such as obesity, physical activity, sexual activity, smoking and occupation have been also associated with prostate cancer risk, but their roles in prostate cancer etiology remain uncertain. This mini-review aims to provide risk factors, disease knowledge, prevalence and awareness about prostate cancer.

    Between November 1998 and December 1999, trained medical record abstractors visited the Micronesian jurisdictions of Chuuk, Kosrae, Pohnpei, and Yap (the four states of the Federated States of Micronesia), as well as the Republic of Palau (Belau), the Republic of Kiribati, the Republic of the Marshall Islands (RMI), and the Republic of Nauru to review all available medical records in order to describe the epidemiology of cancer in Micronesia. Annualized age-adjusted, site-specific cancer period prevalence rates for individual jurisdictions were calculated. Site-specific cancer occurrence in Micronesia follows a pattern characteristic of developing nations. At the same time, cancers associated with developed countries are also impacting these populations. Recommended are jurisdiction-specific plans that outline the steps and resources needed to establish or improve local cancer registries; expand cancer awareness and screening activities; and improve diagnostic and treatment capacity.

    Simulating cancer behavior across multiple biological scales in space and time, i.e., multiscale cancer modeling, is increasingly being recognized as a powerful tool to refine hypotheses, focus experiments, and enable more accurate predictions. A growing number of examples illustrate the value of this approach in providing quantitative insights in the initiation, progression, and treatment of cancer. In this review, we introduce the most recent and important multiscale cancer modeling works that have successfully established a mechanistic link between different biological scales. Biophysical, biochemical, and biomechanical factors are considered in these models. We also discuss innovative, cutting-edge modeling methods that are moving predictive multiscale cancer modeling toward clinical application. Furthermore, because the development of multiscale cancer models requires a new level of collaboration among scientists from a variety of fields such as biology, medicine, physics, mathematics, engineering, and computer science, an innovative Web-based infrastructure is needed to support this growing community.

However, methodological challenges still remain to be addressed, especially in cancer epidemiology...... studies among the elderly and the oldest-old. For example, a characteristic pattern for many cancer types is that the incidence increases up to a maximum at about ages 75-90 years and is then followed by a decline or a leveling off at the oldest ages. It has been suggested that the oldest individuals may...... be asymptomatic, or even insusceptible to cancer. An alternative interpretation is that this pattern is an artifact due to lower diagnostic intensity among the elderly and oldest-old caused by higher levels of co-morbidities in this age group. Currently, the available cancer epidemiology data are not able...

    Bioprinting offers the ability to create highly complex 3D architectures with living cells. This cutting-edge technique has significantly gained popularity and applicability in several fields. Bioprinting methods have been developed to effectively and rapidly pattern living cells, biological macromolecules, and biomaterials. These technologies hold great potential for applications in cancer research. Bioprinted cancer models represent a significant improvement over previous 2D models by mimicking 3D complexity and facilitating physiologically relevant cell-cell and cell-matrix interactions. Here we review bioprinting methods based on inkjet, microextrusion, and laser technologies and compare 3D cancer models with 2D cancer models. We discuss bioprinted models that mimic the tumor microenvironment, providing a platform for deeper understanding of cancer pathology, anticancer drug screening, and cancer treatment development.

    Breakdown of the extracellular matrix is crucial for cancer invasion and metastasis. It is accomplished by the concerted action of several proteases, including the serine protease plasmin and a number of matrix metalloproteases.The activity of each of these proteases is regulated by an array......, the regulation of extracellular proteolysis in cancer involves a complex interplay between cancer cells and non-malignant stromal cells in the expression of the molecular components involved. For some types of cancer, this cellular interplay mimics that observed in the tissue of ori- gin during non......-neoplastic tissue remodelling processes.We propose that cancer invasion can be considered as uncontrolled tissue remodelling. Inhibition of extracellular proteases is an attractive approach to cancer therapy. Because proteases have many different functions in the normal organism, efficient inhibition will have...

    Full Text Available Cancer diagnosis which is used as synonym of “death”, “pain” and “sorrow” leads to a hard-coping period in these patients which requires a rapid intervention. Studies conducted in cancer patients regarding prevalance of psychiatric illnesses reported rates ranging from 9 % to 60%. In many cancer patients, psychiatric disorders can be seen as a reaction to disease or cancer tratment, while in ten precent of cases it can be seen as an aggrevation of premorbid personality disorders or anxiety disorders. Although psychiatric disorders in cancer patients can be treated and by this way, morbidity and mortality of these disorders can be prevented, these disorders are underdiagnosed and not properly treated in many patients. In this article, we briefly reviewed literature about psychiatric disorders and symptoms in cancer patients, their diagnosis and treatment suggestions.

    Aneuploidy has long been recognized to be a cardinal feature of many neoplasias. However, the role of aneuploidy in tumorigenesis continues to be a matter of debate. We believe that aneuploidy in cancers is the result of chromosomal instability, a process in which dividing cancer cells segregate their chromosomes with decreased fidelity. Here we discuss our definition of chromosomal instability, evidence for its causal role in tumor development, and suggestions regarding the mechanisms that initiate chromosomal instability in cancer cells.

    Full Text Available The applications of functional genomics, proteomics and informatics to cancer research have yielded a tremendous amount of information, which is growing all the time. Much of this information is available publicly on the Internet and ranges from general information about different cancers from a patient or clinical viewpoint, through to databases suitable for cancer researchers of all backgrounds, to very specific sites dedicated to individual genes or molecules. A simple search for ‘cancer’ from a typical Web browser search engine yields more than half a million hits; an even more specific search for ‘leukaemia’ (>40 000 hits or ‘p53’ (>5700 hits yields far too many hits to allow one to identify particular sites of interest. This review aims to provide a brief guide to some of the resources and databases that can be used as springboards to home in rapidly on information relevant to many fields of cancer research. As such, this article will not focus on a single website but hopes to illustrate some of the ways that postgenomic biology is revolutionizing cancer research. It will cover genomics and proteomics approaches that have been applied to studying global expression patterns in cancers, in addition to providing links ranging from general information about cancer to specific cancer gene mutation databases.

  13. Dairy products and cancer.

    Science.gov (United States)

    Lampe, Johanna W

    2011-10-01

    Cancer is a group of more than 100 diseases in which cells display uncontrolled growth, invasion, and sometimes metastasis. Milk and dairy products contain micronutrients and several bioactive constituents that may influence cancer risk and progression. Much of the focus of human, population-based studies has been on the effects of intake of milk and total dairy products or of calcium intake. Based on a systematic review of the epidemiologic literature, the World Cancer Research Fund and American Institute for Cancer Research report concluded there was a probable association between milk intake and lower risk of colorectal cancer, a probable association between diets high in calcium and increased risk of prostate cancer, and limited evidence of an association between milk intake and lower risk of bladder cancer. For other cancers, the evidence was mixed or lacking. Since the 2007 report, several additional, large-cohort studies have been published, including two that show an inverse association between intake of cultured dairy products and bladder cancer. Little is known about the potential effect of various bioactives produced during rumen microbe metabolism on cancer risk. Furthermore, studies support a role of live microbes present in some dairy products in the modulation of the human gut microbial community and gut metabolism. Given the growing appreciation for the role of the gut microbial community in relation to immune function and health and disease, including cancer, the potential role of various dairy products in the modulation of the human gut microbiome warrants further evaluation. Key teaching points: As a dietary exposure, dairy products are a complex group of foods and composition varies by region, which makes evaluation of their association with disease risk difficult. For most cancers, associations between cancer risk and intake of milk and dairy products have been examined only in a small number of cohort studies, and data are inconsistent or

    Full Text Available Richard R LoveThe Ohio State University Comprehensive Cancer Center, Columbus, OH, USAAbstract: Cancer is an increasing problem for low- and middle-income countries undergoing an epidemiologic transition from dominantly acute communicable disease to more frequent chronic disease with increased public health successes in the former domain. Progress against cancer in high-income countries has been modest and has come at enormous expense. There are several well-conceived global policy and planning initiatives which, with adequate political will, can favorably impact the growing global cancer challenges. Most financial resources for cancer, however, are spent on diagnosis and management of patients with disease in circumstances where specific knowledge about effective approaches is significantly limited, and the majority of interventions, other than surgery, are not cost-effective in resource-limited countries by global standards. In summary, how to intervene effectively on a global scale for the majority of citizens who develop cancer is poorly defined. In contrast to technology-transfer approaches, markedly increased clinical research activities are more likely to benefit cancer sufferers. In these contexts, a global cancer research initiative is proposed, and mechanisms for realizing such an effort are suggested.Keywords: breast cancer, research, global, international, low-income, middle-income

    Institute of Scientific and Technical Information of China (English)

    Jae Myung Cha; Myung-Hwan Kim; Se Jin Jang

    2007-01-01

    Bile duct cancers are frequently diagnosed as advanced diseases. Over half of patients with advanced bile duct cancer present with unresectable malignancies and their prognosis has been very poor even after curative resections. Although there has been a need to diagnose bile duct cancer at its early stage, it has been a difficult goal to achieve due to our lack of knowledge regarding this disease entity. Early bile duct cancer may be defined as a carcinoma whose invasion is confined within the fibromuscular layer of the extrahepatic bile duct or intrahepatic large bile duct without distant metastasis irrespective of lymph node involvement. Approximately 3%-10% of resected bile duct cancers have been reported to be early cancers in the literature. The clinicopathological features of patients with early bile duct cancer differ from those of patients with advanced bile duct cancer, with more frequent asymptomatic presentation, characteristic histopathological findings,and excellent prognosis. This manuscript is organized to emphasize the need for convening an international consensus to develop the concept of early bile duct cancer.

    Met is a tyrosine kinase receptor that is considered to be a proto-oncogene. The hepatocyte growth factor (HGF)-Met signaling system plays an important role in tumor growth, invasion, and metastasis in many types of malignancies. Furthermore, Met expression has been reported to be a useful predictive biomarker for disease progression and patient survival in these malignancies. Many studies have focused on the clinical significance and prognostic role of Met in urological cancers, including prostate cancer (PCa), renal cell carcinoma (RCC), and urothelial cancer. Several preclinical studies and clinical trials are in progress. In this review, the current understanding of the pathological role of Met in cancer cell lines, its clinical significance in cancer tissues, and its predictive value in patients with urological cancers are summarized. In particular, Met-related malignant behavior in castration-resistant PCa and the different pathological roles Met plays in papillary RCC and other histological types of RCC are the subjects of focus. In addition, the pathological significance of phosphorylated Met in these cancers is shown. In recent years, Met has been recognized as a potential therapeutic target in various types of cancer; therapeutic strategies used by Met-targeted agents in urological cancers are summarized in this review.

    Cancer, a major health problem, affects 12 million people worldwide every year. With surgery and chemo-radiation the long term survival rate for the majority of cancer patients is dismal. Thus novel treatments are urgently needed. Immunotherapy, the harnessing of the immune system to destroy cancer cells is an attractive option with potential for long term anti-tumor benefit. Cytokines are biological response modifiers that stimulate anti-tumor immune responses. In this review, we discuss the anti-tumor efficacy of the chemotactic cytokine CCL21 and its pre-clinical and clinical application in cancer.

    Full Text Available Physical exercise has attracted increased interest in rehabilitation of oncological patients. The purpose of this paper is to review the literature and summarize the evidence of physical exercise in preventing cancer, its ability in attenuating the effect of cancer and its treatments and to provide guidelines for exercise prescription Review of recent literature by electronic search of MEDline (Pub Med, Cancer lit, Cochrane libraries, CINAHL were done using Keywords and the variables were identified and systematically evaluated. There is strong evidence for reduced risk of colorectal and breast cancer with possible association for prostate, endometrial and lung cancer with increasing physical activity. Exercise helps cancer survivors cope with and recover from treatment; exercise may improve the health of long term cancer survivors and extend survival. Physical exercise will benefit throughout the spectrum of cancer. However, an understanding of the amount, type and intensity of exercise needed has not been fully elucidated. There is sufficient evidence to promote exercise in cancer survivors following careful assessment and tailoring on exercise prescription.

    The author believes contaminants in our external environment play a significant role in causing cancer in humans and the cumulative impact of exposure to chemical carcinogens over a lifetime has also to be considered. An efficient method to prevent cancer is to restrict the presence of chemical carcinogens not only indoor, but also in outdoor, environments. Due to collective efforts to reduce tobacco use, lung cancer rates are falling in the USA. Most chemical carcinogens are derived from coal and petroleum, so finding substitutes for these two substances is the right way to proceed in cancer prevention efforts, the author states.

    The greatest risk factor for cancer is aging. Human cancer incidence increases exponentially with advancing age. Cancer growth rate and potential for metastatic spread may be influenced by age-specific change in host response. Because cancer and aging are, thus, inextricably linked, the American Cancer Society should encourage submission of research proposals that address the mechanisms of aging and how aging alters cancer development.

    White, Eileen; Mehnert, Janice M; Chan, Chang S

    Macroautophagy (autophagy hereafter) captures intracellular proteins and organelles and degrades them in lysosomes. The degradation breakdown products are released from lysosomes and recycled into metabolic and biosynthetic pathways. Basal autophagy provides protein and organelle quality control by eliminating damaged cellular components. Starvation-induced autophagy recycles intracellular components into metabolic pathways to sustain mitochondrial metabolic function and energy homeostasis. Recycling by autophagy is essential for yeast and mammals to survive starvation through intracellular nutrient scavenging. Autophagy suppresses degenerative diseases and has a context-dependent role in cancer. In some models, cancer initiation is suppressed by autophagy. By preventing the toxic accumulation of damaged protein and organelles, particularly mitochondria, autophagy limits oxidative stress, chronic tissue damage, and oncogenic signaling, which suppresses cancer initiation. This suggests a role for autophagy stimulation in cancer prevention, although the role of autophagy in the suppression of human cancer is unclear. In contrast, some cancers induce autophagy and are dependent on autophagy for survival. Much in the way that autophagy promotes survival in starvation, cancers can use autophagy-mediated recycling to maintain mitochondrial function and energy homeostasis to meet the elevated metabolic demand of growth and proliferation. Thus, autophagy inhibition may be beneficial for cancer therapy. Moreover, tumors are more autophagy-dependent than normal tissues, suggesting that there is a therapeutic window. Despite these insights, many important unanswered questions remain about the exact mechanisms of autophagy-mediated cancer suppression and promotion, how relevant these observations are to humans, and whether the autophagy pathway can be modulated therapeutically in cancer.

    Prostatic carcinoma (PCa) is a significant cause of cancer morbidity and mortality worldwide. Accurate staging is critical for prognosis assessment and treatment planning for PCa. Despite the large volume of clinical activity and research, the challenge to define the most appropriate and clinically relevant staging system remains. The pathologically complex and uncertain clinical course of prostate cancer further complicates the design of staging classification and a substaging system suitable for individualized care. This review will focus on recent progress and controversial issues related to prostate cancer staging. The 2010 revision of the American Joint Committee on Cancer/Union Internationale Contre le Cancer (AJCC/UICC) tumour, node and metastasis (TNM) system is the most widely used staging system at this time. Despite general acceptance of the system as a whole, there is controversy and uncertainty about its application, particularly for T2 subclassification. The three-tiered T2 classification system for organ-confined prostate cancer is superfluous, considering the biology and anatomy of PCa. A tumour size-based substaging system may be considered in the future TNM subclassification of pT2 cancer. Lymph node status is one of the most important prognostic factors for prostate cancer. Nevertheless, clinical outcomes in patients with positive lymph nodes are variable. Identification of patients at the greatest risk of systemic progression helps in the selection of appropriate therapy. The data suggest that the inherent aggressiveness of metastatic prostate cancer is closely linked to the tumour volume of lymph node metastasis. We recommend that a future TNM staging system should consider subclassification of node-positive cancer on the basis of nodal cancer volume, using the diameter of the largest nodal metastasis and/or the number of positive nodes.

    In this article, the American Cancer Society provides an overview of female breast cancer statistics in the United States, including trends in incidence, mortality, survival, and screening. Approximately 230,480 new cases of invasive breast cancer and 39,520 breast cancer deaths are expected to occur among US women in 2011. Breast cancer incidence rates were stable among all racial/ethnic groups from 2004 to 2008. Breast cancer death rates have been declining since the early 1990s for all women except American Indians/Alaska Natives, among whom rates have remained stable. Disparities in breast cancer death rates are evident by state, socioeconomic status, and race/ethnicity. While significant declines in mortality rates were observed for 36 states and the District of Columbia over the past 10 years, rates for 14 states remained level. Analyses by county-level poverty rates showed that the decrease in mortality rates began later and was slower among women residing in poor areas. As a result, the highest breast cancer death rates shifted from the affluent areas to the poor areas in the early 1990s. Screening rates continue to be lower in poor women compared with non-poor women, despite much progress in increasing mammography utilization. In 2008, 51.4% of poor women had undergone a screening mammogram in the past 2 years compared with 72.8% of non-poor women. Encouraging patients aged 40 years and older to have annual mammography and a clinical breast examination is the single most important step that clinicians can take to reduce suffering and death from breast cancer. Clinicians should also ensure that patients at high risk of breast cancer are identified and offered appropriate screening and follow-up. Continued progress in the control of breast cancer will require sustained and increased efforts to provide high-quality screening, diagnosis, and treatment to all segments of the population.

    Full Text Available Nanotechnology is an interdisciplinary field as a combination of engineering, biology and medicine. It manipulates atoms and molecules to create devices at atomic, molecular and supramolecular levels for potential clinical use. Cancer nanotechnology as the latest trend in cancer diagnosis and treatment has provided nanoscale tools like biosensors, dendrimers, quantum dots and magnetic nanoparticles such as iron oxide with unique optical, magnetic and electronic properties. They are 100 to 1,000-fold smaller than cancer cells and may be conjugated with several functional molecules like imaging probes, specific ligands and antibodies. The capability of transferring through leaky blood vessels, passive and active targeting, intracellular delivery and subcellular localization has made them dual-purpose and multifunctional probes in cancer. Conventional imaging techniques such as CT and MRI using nontargeted contrast agents have limitations in early and accurate diagnosis and monitoring of treatment that may be eventually removed through the use of nanostructures' properties."nCancer diagnosis in an early stage, which influences the patient's survival, is possible earlier than ever imaginable. For example in contrast to mammography, which can detect breast cancer when it has at least 1000,000 cells, these new tools can accurately detect the tumor when it has less than 100 cells. "nThis article is a review on applications of nanotechnology, as a rapidly growing field for cancer imaging in medicine contributing to the early detection of cancer cells through available imaging techniques.

  3. Immunotherapy for Lung Cancers

    2011-01-01

    Full Text Available Lung cancer is the leading cause of cancer-related deaths worldwide. Although treatment methods in surgery, irradiation, and chemotherapy have improved, prognosis remains unsatisfactory and developing new therapeutic strategies is still an urgent demand. Immunotherapy is a novel therapeutic approach wherein activated immune cells can specifically kill tumor cells by recognition of tumor-associated antigens without damage to normal cells. Several lung cancer vaccines have demonstrated prolonged survival time in phase II and phase III trials, and several clinical trials are under investigation. However, many clinical trials involving cancer vaccination with defined tumor antigens work in only a small number of patients. Cancer immunotherapy is not completely effective in eradicating tumor cells because tumor cells escape from host immune scrutiny. Understanding of the mechanism of immune evasion regulated by tumor cells is required for the development of more effective immunotherapeutic approaches against lung cancer. This paper discusses the identification of tumor antigens in lung cancer, tumor immune escape mechanisms, and clinical vaccine trials in lung cancer.

    Lung cancer is the leading cause of cancer death among both men and women in the United States. It is also the leading cause of cancer death among men and the second leading cause of cancer death among women worldwide. Lung cancer rates and trends vary substantially by sex, age, race/ethnicity, socioeconomic status, and geography because of differences in historical smoking patterns. Lung cancer mortality rates in the United States are highest among males, blacks, people of lower socioeconomic status, and in the mid-South (e.g., Kentucky, Mississippi, Arkansas, and Tennessee). Globally, rates are highest in countries where smoking uptake began earliest, such as those in North America and Europe. Although rates are now decreasing in most of these countries (e.g., United States, United Kingdom, Australia), especially in men, they are increasing in countries where smoking uptake occurred later. Low- and middle-income countries now account for more than 50% of lung cancer deaths each year. This chapter reviews lung cancer incidence and mortality patterns in the United States and globally.

    2016-01-01

    Diabetes and cancer are common conditions, affecting 384 million and 33 million people worldwide, respectively. Therefore, there is great potential for overlap, with people with diabetes also developing cancer and vice versa. However, people with diabetes may be at increased risk of developing cancer when compared with the general population. This is due to both shared risk factors associated with the two diseases and the metabolic derangements associated with diabetes, such as hyperglycaemia, insulin resistance, hyperinsulinaemia and oxidative stress. Glucose-lowering therapies may influence the risk of cancer in people with type 2 diabetes due to these therapies' effects on risk factors that are common to both conditions, including hyperglycaemia and obesity, as well as effects that are specific to the class of drug or drugs. Drugs that reduce circulating insulin levels, such as metformin, may reduce cancer risk, and drugs that increase circulating insulin levels, including exogenous insulin and insulin secretagogues, may increase cancer risk. The influence of glucose-lowering therapies on cancer risk may become an important consideration when selecting glucose-lowering therapies to treat people with type 2 diabetes and a high risk of cancer occurrence or recurrence.
