Full Text Available Se practicaron lesiones estereo-táxicas bilaterales en los ganglios basales en 10 cadáveres utilizando como aparato estero-táxico la guía para ganglios basales diseñada por Cooper y la cánula de Cooper. Se encontró que la guía debe modificarse haciendo la adaptación al tornillo que hace los movimientos coronales de una escala medidora de ángulos, lográndose de esta manera la medición matemática de los movimientos en todos los planos. Se usó como punto de referencia para la localización de las lesiones el estudio ventrículo-gráfico. Los ventrículos en el cadáver fueron posibles mediante el uso de la bomba de Thompson. Diez de las lesiones fueron localizadas en el globus pálido. Seis en tálamo óptico. Dos en la cápsula interna, caso no. 3. Sin visualización del agujero de monro. Una de la línea media, caso no. 2, sin control radiológico y una en el putamen, caso no. 1 donde se apreciaron dos lesiones; una el el globus pálido y otra en el putamen. Se encontró que los orificios de trepanación deben realizarse a doce centímetros del nasión y a cuatro centímetros de la línea media, pues la medida aconsejada por otros autores de 14 cms. de distancia del nasión caen sobre la corteza motora. Al no haber llena miento ventricular en uno de los casos, caso no. 6, se encontró la utilidad de los puntos de reparo óseos descritos anteriormente.

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. El análisis morfométrico demostró que en nuestros cultivos el 85% de las neuronas presentes son de pequeño diámetro (<25

Full Text Available La cirugía mayor ambulatoria y de corta estadía constituye un método eficaz y seguro si se hace una selección adecuada de los enfermos y se utilizan técnicas quirúrgicas depuradas con la creación consecuente de la infraestructura para tales fines. Tradicionalmente, el cáncer de mama ha requerido ingreso hospitalario por el riesgo de hemorragia posoperatoria, la necesidad del control de los drenajes quirúrgicos, etc. Internacionalmente esto ha cambiado tras la introducción de nuevas técnicas quirúrgicas como la biopsia del ganglio centinela, la estandarización de las técnicas preservadoras de tejido mamario, así como la especialización de grupos de cirugía en afecciones de la mama. La creación de un grupo de mastología en nuestro centro permitió incursionar en esta modalidad y ya podamos contar 31 pacientes operadas entre enero de 2004 y junio de 2006. Fueron utilizadas diferentes técnicas quirúrgicas con cirugía de corta estadía, previo establecimiento de los criterios de selección. Pudimos concluir que el tratamiento ambulatorio del cáncer de mama en casos seleccionados es factible, dado que se garantiza la seguridad de la paciente, la calidad asistencial y la continuidad en la atención, que además facilita la recuperación psicológica de la enferma y su reinserción temprana en la familiaAmbulatory major surgery with short hospitalization period is an efficient and safe method if a proper selection of patients is made and refined surgical techniques are used, all supported on adequate infrastructure to this end. Traditionally, breast cancer has required admission at hospital due to postsurgical hemorrhage risk, need for surgical drainage control, etc. This has changed worlwide after the introduction of new surgical techniques as sentinel node biopsy, standardization of preserving techniques for breast tissue and specialization of surgeon teams in breast illnesses.

Full Text Available Glycosphingolipids (GSLs, which consist of a hydrophobic ceramide backbone and a hydrophilic carbohydrate residue, are an important type of glycolipid expressed in surface membranes of all animal cells. GSLs play essential roles in maintenance of plasma membrane stability, in regulation of numerous cellular processes (including adhesion, proliferation, apoptosis, and recognition, and in modulation of signal transduction pathways. GSLs have traditionally been classified as ganglio-series, lacto-series, or globo-series on the basis of their diverse types of oligosaccharide chains. Structures and functions of specific GSLs are also determined by their oligosaccharide chains. Different cells and tissues show differential expression of GSLs, and changes in structures of GSL glycan moieties occur during development of numerous types of human cancer. Association of GSLs and/or related enzymes with initiation and progression of cancer has been documented in 100s of studies, and many such GSLs are useful markers or targets for cancer diagnosis or therapy. In this review, we summarize (i recent studies on aberrant expression and distribution of GSLs in common human cancers (breast, lung, colorectal, melanoma, prostate, ovarian, leukemia, renal, bladder, gastric; (ii biological functions of specific GSLs in these cancers.

Full Text Available Objetivo: Valorar la descripción geoestadística realizada de los datos de gripe recogidos a través de la Red Centinela Sanitaria de la Comunidad Valenciana (RCSCV mediante la utilización del método kriging con la finalidad de evaluar la posibilidad de su incorporación a la vigilancia rutinaria Método: Se han utilizado los datos de vigilancia de gripe de la RCSCV en tres temporadas gripales (1997-1998, 1998-1999 y 1999-2000, construyéndose una matriz de datos de incidencia de gripe geocodificada. 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.

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

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

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.

Full Text Available En el presente trabajo se compararon tres técnicas para la aplicación de dos tipos de trazadores retrógrados fluorescentes (Dil y Fluorogold, con el fin de identificar las neuronas motoras y sensoriales que contribuyen con fibras al nervio ciático en ratones adultos. Se ensayó la aplicación de cristales directamente en el nervio, la inyección intraneural y la impregnación del nervio seccionado usando una cámara de silicona. La localización específica de las neuronas motoras en la médula espinal y las neuronas sensoriales en los ganglios de la raíz dorsal que aportan al nervio ciático de ratón se logró aplicando el Fluorogold mediante una cámara en el cabo proximal de los nervios previamente seccionados. Al utilizar el trazador Dil, la misma técnica no permitió hacer la identificación específica de las neuronas. Se encontró que al nervio ciático de ratón podrían contribuir el ganglio de la raíz dorsal más rostrales que los informados para ratas. Estos resultados muestran que la metodología de aplicación de neurotrazadores en cápsula y la descalcificación de tejidos es útil para la localización de neuronas de ganglios de raíz dorsal y de la médula espinal que componen el nervio ciático de ratón adulto, lo que en el futuro permitirá obtener mayor información sobre la neuroanatomía básica del ratón.

Full Text Available Damos a conocer el hallazgo de una adenopatía axilar pigmentada durante la realización de una mastectomía bilateral profiláctica en una paciente de 35 años. El estudio anatomopatológico reveló pigmento compatible con tinta en el interior del ganglio. Esto, junto con la presencia de un tatuaje próximo a la axila de la paciente, permitió identificar el tatuaje como causa de la coloración de la adenopatía. Discutimos el diagnóstico diferencial a realizar en casos similares. Hasta un tercio de la población joven en España se ha realizado algún tatuaje, y las series de autopsias muestran la alta incidencia de presencia de pigmento en ganglios próximos a esos tatuajes. Creemos necesario realizar un correcto diagnóstico diferencial con melanoma y otras etiologías en pacientes tatuados para llevar a cabo una adecuada indicación quirúrgica.

BASAL GANGLIA INVOLVEMENT IN DENGUE HEMORRHAGIC FEVER (DHF

ABSTRACT

Dengue fever is a systemic viral infection transmitted to humans by the female Aedes aegypti mosquito. About 10% of patients with dengue fever may develop neurological disorders during or after infection. There are some signs known as warning signs, which, associated to the epidemiological background (origin of endemic area, may help to suspect the infection in those patients from endemic areas. Here are some generalities of the virus, its clinical forms, complications and the analysis of a systematic review of 65 clinical records of patients diagnosed with dengue and / or dengue hemorrhagic fever. From these patients, it was found that neurological signs and symptoms were evident in 4 of the 39 cases that fulfilled inclusion criteria. This review allowed to detect a case of hemorrhage in the head of the Caudate Nucleus associated with thrombocytopenia, induced by dengue virus.

Roth, M

1994-01-01

Traumatic spondylolysis in a hedgehog is reported. On the basis of that rare observation the "dysplastic" thinning of the vertebral isthmus frequently associated with spondylolysis in man is claimed to be related to the "neuroenveloping" function of the spine shared with that of the neurocranium. Dysplasia of the isthmus results from abnormal ganglio-foraminal interrelation in the embryo rather than from any primary derangement of the vertebral bone growth proper.

Full Text Available The taxonomic location of the Onychophora has been controversial because of their phenotypic and genotypic characteristics, related to both annelids and arthropods. We analyzed the ultrastructure of the neurons and their synapses in the cephalic ganglion of a poorly known invertebrate, the velvet worm Peripatus sedgwicki, from the mountainous region of El Valle, Mérida, Venezuela. Cephalic ganglia were dissected, fixed and processed for transmission electron microscopy. The animal has a high degree of neurobiological development, as evidenced by the presence of asymmetric (excitatory and symmetric (inhibitory synapses, as well as the existence of glial cell processes in a wide neuropile zone. The postsynaptic terminals were seen to contain subsynaptic cisterns formed by membranes of smooth endoplasmic reticulum beneath the postsynaptic density, whereas the presynaptic terminal showed numerous electron transparent synaptic vesicles. From the neurophylogenetic perspectives, the ultrastructural characteristics of the central nervous tissue of the Onychophora show important evolutionary acquirements, such as the presence of both excitatory and inhibitory synapses, indicating functional synaptic transmission, and the appearance of mature glial cells.

Full Text Available RESUMEN Es artículo analiza el caso de los centinelas del muro de Berlín que disparaban y mataron a algunas personas –que querían pasar la frontera-, amparados por una interpretación del Derecho de la RDA. Algunos años después de la unificación alemana, el Tribunal Constitucional condenó  aquellos soldados por asesinato con el argumento que se trataba de Derecho “extremadamente injusto”. Esta es una forma particular  de aplicación de la fórmula de Radburch. El objetivo de este artículo es estudiar el caso de los centinelas del Muro de Berlín bajo la perspectiva del la Filosofía del Derecho, particularmente en la controversia entre positivismo y iusnaturalismo. En este sentido, se comparan los enfoques de Kelsen y Radburch sobre el Derecho nazi. Y también se estudia la polémica Hart Fuller sobre el caso de “delator rencoroso”.   ABSTRACT This article analyzes the case of the border guards of the Berlin Wall that have shot and killed some people -who wanted pass the frontier- and those soldiers were protected by some legal interpretation under the German Democratic Republic Law. Some years after the German unification, the Constitutional Court condemned those soldiers for murder with the argument that that was an “extremely unjust” Law. This was a particular form of application of the Radburch’s formula. The objective of this article is studying the case of the Berlin Wall border guards under the perspective of the Philosophy of Law, particularly the controversy between positivism and iusnaturalism. In this sense, they are compared Kelsen and Radbruch approaches on Nazi law. And also it’s studied the Hart-Fuller polemics on the ‘grudge infomer’ case.

In this work the process for the detection and/or removal of the sentinel lymph node and nonpalpable lesions has been optimized. For the latter, a {sup 1}25 I, seed an isotope that is not usually used for this purpose, is employed. It was recycled from radiotherapy treatments surpluses, having requested the necessary authorizations. A detailed procedure for the management, storage, transport and sterilization of the {sup 1}25 I seed in the hospital has been developed. A custom protocol has been defined for quality control of intraoperative probes with different tests, providing methods, frequencies, tolerances, etc. The overall result is an improvement of the process and a decrease of the inconveniences for the patient.

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

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

Calcificaciones cerebrales extensas y corea, en hipoparatiroidismo probablemente posquirúrgico

Directory of Open Access Journals (Sweden)

David Lira

2009-06-01

Full Text Available Introducción: Las calcificaciones cerebrales pueden ser unilaterales o bilaterales; las unilaterales presentan como etiología las infecciones, infartos o traumatismos; las bilaterales pueden ser fisiológicas, metabólicas o idiopáticas. Caso clínico: Paciente mujer, de 48 años de edad, tiroidectomizada hace 27 años, tomaba levotiroxina; acudió por movimientos involuntarios coreicos y balísticos progresivos y dificultad para caminar. Se encontró hipotonía de hemicuerpo derecho y movimientos serpenteantes de miembro superior derecho, hipocalcemia, hiperfosfatemia y concentración baja de parathormona; la tomografia y resonancia magnética cerebrales evidenciaban calcificaciones bilaterales en ganglios basales y cerebelo. Recibió tratamiento con citrato de calcio, calcitriol y risperidona, con recuperación completa. Discusión: Los pacientes con calcificaciones de ganglios basales presentan síntomas extrapiramidales (20 a 30%, como parkinsonismo o coreoatetosis, convulsiones y trastornos neuropsiquiátricos. Las calcificaciones intracerebrales bilaterales se producen generalmente por depósito de calcio y otros minerales. El hipoparatiroidismo es una complicación frecuente en la tiroidectomía radical, con hipocalcemia, hiperfosfatemia y concentración baja de parathormona como el caso descrito. Algunos pacientes no desarrollan los síntomas de inmediato. El tratamiento mejora los síntomas sin alterar las calcificaciones, como en la paciente, en quien la mejoría sería por la normalización del calcio más que por la risperidona.

Full Text Available Se analizaron 200 pacientes con diagnóstico de cáncer de mama, en un período de 5 años (Enero 2007 a Enero 2012 que fueron diagnosticados y tratados en la consulta especializada de mama en el Servicio de Oncología del Hospital Universitario de Sancti-Spíritus. Se estudiaron los factores pronósticos relacionados con el tumor primario, la presencia de ganglios metastásico, el tratamiento efectuado, el tiempo libre de enfermedad y el tiempo de sobrevida. Se comprobó en nuestra serie el predominio de pacientes con 60 años y más, con localización más frecuente en la mama izquierda, y el cuadrante superior-externo fue el sitio mamario más afectado. Los factores pronóstico significativos y de mayor relevancia en cuanto al tiempo libre de enfermedad y tiempo de sobrevida fueron: tamaño tumoral, status ganglionar, infiltración periganglionar y la determinación de la hormono dependencia. Se demostró que en la medida que aumenta el tamaño del tumor primario (T y la afectación ganglionar regional (N, la etapa clínica sea más avanzada y los ganglios axilares en la pieza quirúrgica metastásicos condicionan que exista mayor posibilidad de que ocurra recurrencia tumoral, con una incidencia mayor a presentar metástasis a distancia y que ocurra la muerte en estas pacientes.

Full Text Available El potencial pandémico de la gripe ha convertido a esta enfermedad en el objetivo preferente de los sistemas de vigilancia nacionales e internacionales. Los sistemas centinela, por sus características, permiten una integración de información virológica y epidemiológica de esta enfermedad de elevada incidencia, ayudando a detectar y caracterizar precozmente los virus de la gripe circulantes y evaluando su capacidad de propagación en la población. La creación en España, hace más de 10 años, de un sistema centinela, que cubre actualmente el 75% de la población nacional, supuso una forma diferente de abordar la vigilancia de la gripe humana, a través de la declaración individualizada de los casos de la enfermedad y la unión de datos clínicos, epidemiológicos y microbiológicos, y ha contribuido a una evaluación más correcta de la actividad de la gripe en el territorio español. A pesar de las limitaciones de este sistema centinela, derivadas fundamentalmente de los problemas de representatividad que todo sistema de vigilancia basado en muestras de población puede presentar, los datos que aporta se han revelado útiles para el seguimiento y el control de la gripe. La rapidez en la transmisión de la información es uno de los principales atributos del sistema, que posibilita su integración en las redes de vigilancia internacional de la enfermedad y ayuda a lograr una mejor oportunidad en la difusión de la información y formulación de recomendaciones.The pandemic potential of influenza has made this disease the principal target of both national and international surveillance systems.

Su importancia radica puesto que es una de las vías que tiene el virus para llegar a sistema nervioso central. El virus de la rabia usualmente entra por la mordedura de un animal infectado, inicialmente llega al músculo, replicándose localmente, pasa a terminales nerviosas adyacentes, sube a través del sistema nervioso periférico y llega a los ganglio de la raíz dorsal. Durante el transporte del virus no hay síntomas y la enfermedad sólo se inicia con la llegada del virus al sistema nervioso central, donde la replicación del virus es seguida por su transporte en sentido centrífugo, teniendo un particular e inexplicable tropismo por las glándulas salivares y lacrimales. Objetivo: Describir el proceso de infección del virus de la rabia en neuronas GRD. Metodología: Cultivos de neuronas de GRD de ratón adulto fueron inoculados con virus de rabia cepa CVS, siendo observada la ultraestructura en tiempos progresivos de infección desde 5 minutos hasta 60 horas. Los resultados obtenidos en los que no se observaron viriones, nos llevaron a hacer un marcaje con inmunoperoxidasas para evidenciar este proceso. Para corroborar los resultados obtenidos fue necesario comparar ultraestructuralmente y con la técnica de inmunoperoxidasas la infección en tejido cerebral de ratones adultos inoculados experimentalmente. Resultados: Este estudio nos permite afirmar que la producción de partículas virales en neuronas de ganglio de raíz dorsal de ratón adulto, cultivadas in vitro, e inoculadas con virus de rabia es escasa, comparada con la gran cantidad de antígeno viral observada en vesículas de 0,5 mm localizadas en el citoplasma de estas mismas células.

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

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

Pancreatic cancer is an aggressive malignant solid tumor well-known by early metastasis, local invasion, resistance to standard chemo- and radiotherapy and poor prognosis. Increasing evidence indicates that pancreatic cancer is initiated and propagated by cancer stem cells (CSCs). Here we review the current research results regarding CSCs in pancreatic cancer and discuss the different markers identifying pancreatic CSCs. This review will focus on metastasis, microRNA regulation and anti-CSC therapy in pancreatic cancer.

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

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

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

Kleinerman, R.A.; Curtis, R.E.; Boice, J.D. Jr.; Flannery, J.T.; Fraumeni, J.F. Jr.

1982-01-01

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

1993-01-01

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

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

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

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

Cancer in Punjab: evidence from cancer atlas

Directory of Open Access Journals (Sweden)

2015-09-01

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

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

Maternal lung cancer and testicular cancer risk in the offspring.

Science.gov (United States)

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

2003-07-01

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

How Can We Treat Cancer Disease Not Cancer Cells?

Science.gov (United States)

Kim, Kyu-Won; Lee, Su-Jae; Kim, Woo-Young; Seo, Ji Hae; Lee, Ho-Young

2017-01-01

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

Cancer nanomedicine: gold nanoparticle mediated combined cancer therapy

Science.gov (United States)

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

2018-02-01

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

Attitudes and Stereotypes in Lung Cancer versus Breast Cancer.

Directory of Open Access Journals (Sweden)

N Sriram

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

Cancer cells are highly glycolytic for energy production, exhibit the Warburg effect, establish aggressive acidic microenvironment, maintain cancer stem cells, exhibit resistance to chemotherapy, have low antioxidant systems but different ΔΨm (delta psi, mitochondrial transmembrane potential, express P-glycoprotein for multidrug resistance, upregulate glucose transporters and monocarboxylate transporters and are under high steady-state reactive oxygen species conditions. Normal cells differ in all these aspects. Lactate produced through the Warburg effect helps cancer metastasis. Targeting glycolysis reactions for energy production in cancer cells seems promising in decreasing the proliferation and metastasis of cancer cells. 3-bromopyruvate makes use of cancer biology in treating cancer cells, cancer stem cells and preventing metastasis in human cancer as discussed in this review. Updated advances are analyzed here, which include research analysis of background, experience, readings in the field of cancer biology, oncology and biochemistry.

Cancer stem cells, cancer cell plasticity and radiation therapy.

Science.gov (United States)

Vlashi, Erina; Pajonk, Frank

2015-04-01

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

Cancer survivorship: a new challenge in comprehensive cancer control.

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

2005-10-01

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

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

Science.gov (United States)

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

2018-02-01

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

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

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

Italian cancer figures, report 2009: Cancer trend (1998-2005).

Science.gov (United States)

2009-01-01

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

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

Cancer-Related Fatigue in Cancer Survivorship.

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

2017-11-01

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

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

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

Effects of irradiation for cervical cancer on subsequent breast cancer

International Nuclear Information System (INIS)

Harlan, L.C.M.

1985-01-01

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

He, J

2018-01-23

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

1989-01-01

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

Cancer cachexia

Directory of Open Access Journals (Sweden)

Nada Rotovnik Kozjek

2013-02-01

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

Cancer screening guidelines.

Science.gov (United States)

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

2001-03-15

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

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

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

Breast cancer 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.

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

Lung Cancer

Maghfoor, Irfan; Perry, M.C.

2005-01-01

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

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

Science.gov (United States)

Nelson, Laura C

2017-01-01

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

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

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

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

Science.gov (United States)

Campbell, Lisa C; McClain, Jasmyne

2013-12-01

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

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

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

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

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

2015-11-01

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

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

Science.gov (United States)

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

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

Haynes-Maslow, Lindsey; Allicock, Marlyn; Johnson, La-Shell

2016-03-01

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

Cancer in first-degree relatives and risk of testicular cancer in Denmark

2011-01-01

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

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

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

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

Energy Technology Data Exchange (ETDEWEB)

Lesko, Samuel M.

2007-07-31

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

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

Science.gov (United States)

Yeh, Albert C; Ramaswamy, Sridhar

2015-12-01

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

Handberg, C; Lomborg, K; Nielsen, C V; Oliffe, J L; Midtgaard, J

2015-11-01

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

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

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

2011-01-01

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

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

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

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

Science.gov (United States)

Thomson, Maria D; Siminoff, Laura A

2018-04-16

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

Targeting Stromal-Cancer Cell Crosstalk Networks in Ovarian Cancer Treatment

Directory of Open Access Journals (Sweden)

Tsz-Lun Yeung

2016-01-01

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

[Sexy cancer--sexuality for cancer patients].

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

2009-09-01

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

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

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

Thyroid Cancer Presenting with Concomitant Metastatic Breast Cancer in the Thyroid

Directory of Open Access Journals (Sweden)

Chung-Chen Wang

2014-12-01

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

Cancer3D: understanding cancer mutations through protein structures.

Science.gov (United States)

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

2015-01-01

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

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

Oral cancer.

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

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

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

Gastric cancer

International Nuclear Information System (INIS)

Salek, T.

2007-01-01

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

Cancer and tumour markers

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

Adipocyte activation of cancer stem cell signaling in breast cancer

Institute of Scientific and Technical Information of China (English)

Benjamin; Wolfson; Gabriel; Eades; Qun; Zhou

2015-01-01

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

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

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

Berman, Tara A; Schiller, John T

2017-06-15

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

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

Ovarian Cancer Stroma: Pathophysiology and the Roles in Cancer Development

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

The Implications of Cancer Stem Cells for Cancer Therapy

Directory of Open Access Journals (Sweden)

Wenjing Jiang

2012-12-01

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

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

Colorectal cancer (CRC) is the second most common cancer in women and the third most common in men. Adenocarcinoma accounts for 90% of CRC cases. There has been accumulating evidence in support of the cancer stem cell (CSC) concept of cancer which proposes that CSCs are central in the initiation of cancer. CSCs have been the focus of study in a range of cancers, including CRC. This has led to the identification and understanding of genes involved in the induction and maintenance of pluripotency of stem cells, and markers for CSCs, including those investigated specifically in CRC. Knowledge of the expression pattern of CSCs in CRC has been increasing in recent years, revealing a heterogeneous population of cells within CRC ranging from pluripotent to differentiated cells, with overlapping and sometimes unique combinations of markers. This review summarises current literature on the understanding of CSCs in CRC, including evidence of the presence of CSC subpopulations, and the stem cell markers currently used to identify and localise these CSC subpopulations. Future research into this field may lead to improved methods for early detection of CRC, novel therapy and monitoring of treatment for CRC and other cancer types. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

A 68-year-old man was referred to our outpatient clinic with left renal cell cancer and bladder cancer. He had undergone combination therapy comprising chemotherapy plus radiation therapy following radical orchiectomy for testicular cancer at the age of 48 years. The right testis could be felt within the scrotum, however the left testis could not. Blood tests showed no abnormality in regard to testicular tumor markers. Urine cytology was class V. Computed tomography revealed a 3.0 x 3.4 cm mass in the left kidney and a 4.5 x 1.5 cm mass in the left wall of the bladder. We made it a priority to treat the bladder cancer which was strongly suspected to be invasive cancer. At first the patient underwent radical cystectomy. Then left partial nephrectomy was carried out. Our case would appear to be the 24th case of triple primary urogenital cancer in Japan that consisted of left testicular cancer, left renal cancer and bladder cancer. Our case was also thought to be a case of secondary cancer that developed following treatment for testicular cancer. (author)

Testicular cancer survival rates improved dramatically after cisplatin-based therapy was introduced in the 1970s. However, chemotherapy and radiation therapy are potentially carcinogenic. The purpose of this study was to estimate the risk of developing second primary cancers including the risk associated with primary histologic type (seminoma and non-seminoma) among testicular cancer survivors in Germany. We identified 16 990 and 1401 cases of testicular cancer in population-based cancer registries of East Germany (1961–1989 and 1996–2008) and Saarland (a federal state in West Germany; 1970–2008), respectively. We estimated the risk of a second primary cancer using standardized incidence ratios (SIRs) with 95% confidence intervals (95% CIs). To determine trends, we plotted model-based estimated annual SIRs. In East Germany, a total of 301 second primary cancers of any location were observed between 1961 and 1989 (SIR: 1.9; 95% CI: 1.7–2.1), and 159 cancers (any location) were observed between 1996 and 2008 (SIR: 1.7; 95% CI: 1.4–2.0). The SIRs for contralateral testicular cancer were increased in the registries with a range from 6.0 in Saarland to 13.9 in East Germany. The SIR for seminoma, in particular, was higher in East Germany compared to the other registries. We observed constant trends in the model-based SIRs for contralateral testicular cancers. The majority of reported SIRs of other cancer sites including histology-specific risks showed low precisions of estimated effects, likely due to small sample sizes. Testicular cancer patients are at increased risk especially for cancers of the contralateral testis and should receive intensive follow-ups. PMID:24407180

An actual condition of cancer, and the basis and a future view of radiotherapy were described by adding generally established biological and biochemical knowledge to the author's research. It was described that the relapse of cancer after irradiation was induced from outside of cancerous mass, and the nature of relapsed cancerous cells group was also stated. The histological structure of cancer from a view of cell movement and radioresistant cancerous cells group were described. The differentiation of cancerous cells were described, and a study of inhibition of cancer by redifferentiation was considered. It is important to grasp characteristics and a limit of radiotherapy for cancer, to systematize and materialize reasonable therapy which uses drug and immunotherapy together with surgery, and to use radiotherapy reasonably together with redifferentiation therapy of cancerous cells by extracting characteristics and a limit of radiationtherapy from an actual condition of cancer.

Epigenetics and Colorectal Cancer

Science.gov (United States)

Lao, Victoria Valinluck; Grady, William M.

2012-01-01

Colorectal cancer is a leading cause of cancer deaths in the world. It results from an accumulation of genetic and epigenetic changes in colon epithelial cells that transforms them into adenocarcinomas. There have been major advances in our understanding of cancer epigenetics over the last decade, particularly regarding aberrant DNA methylation. Assessment of the colon cancer epigenome has revealed that virtually all colorectal cancers have aberrantly methylated genes and the average colorectal cancer methylome has hundreds to thousands of abnormally methylated genes. As with gene mutations in the cancer genome, a subset of these methylated genes, called driver genes, is presumed to play a functional role in colorectal cancer. The assessment of methylated genes in colorectal cancers has also revealed a unique molecular subgroup of colorectal cancers called CpG Island Methylator Phenotype (CIMP) cancers; these tumors have a particularly high frequency of methylated genes. The advances in our understanding of aberrant methylation in colorectal cancer has led to epigenetic alterations being developed as clinical biomarkers for diagnostic, prognostic, and therapeutic applications. Progress in the assessment of epigenetic alterations in colorectal cancer and their clinical applications has shown that these alterations will be commonly used in the near future as molecular markers to direct the prevention and treatment of colorectal cancer.

Methylation of Breast Cancer Predisposition Genes in Early-Onset Breast Cancer: Australian Breast Cancer Family Registry.

Directory of Open Access Journals (Sweden)

Cameron M Scott

Full Text Available DNA methylation can mimic the effects of both germline and somatic mutations for cancer predisposition genes such as BRCA1 and p16INK4a. Constitutional DNA methylation of the BRCA1 promoter has been well described and is associated with an increased risk of early-onset breast cancers that have BRCA1-mutation associated histological features. The role of methylation in the context of other breast cancer predisposition genes has been less well studied and often with conflicting or ambiguous outcomes. We examined the role of methylation in known breast cancer susceptibility genes in breast cancer predisposition and tumor development. We applied the Infinium HumanMethylation450 Beadchip (HM450K array to blood and tumor-derived DNA from 43 women diagnosed with breast cancer before the age of 40 years and measured the methylation profiles across promoter regions of BRCA1, BRCA2, ATM, PALB2, CDH1, TP53, FANCM, CHEK2, MLH1, MSH2, MSH6 and PMS2. Prior genetic testing had demonstrated that these women did not carry a germline mutation in BRCA1, ATM, CHEK2, PALB2, TP53, BRCA2, CDH1 or FANCM. In addition to the BRCA1 promoter region, this work identified regions with variable methylation at multiple breast cancer susceptibility genes including PALB2 and MLH1. Methylation at the region of MLH1 in these breast cancers was not associated with microsatellite instability. This work informs future studies of the role of methylation in breast cancer susceptibility gene silencing.

Cancer cachexia represents a debilitating syndrome that diminishes quality of life and augments the toxicities of conventional treatments. Cancer cachexia is particularly debilitating in patients with pancreatic cancer (PC). Mechanisms responsible for cancer cachexia are under investigation and are largely derived from observations in syngeneic murine models of cancer which are limited in PC. We evaluate the effect of human PC cells on both muscle wasting and the systemic inflammatory milieu potentially contributing to PC-associated cachexia. Specifically, human PC xenografts were generated by implantation of pancreatic cancer cells, L3.6pl and PANC-1, either in the flank or orthotopically within the pancreas. Mice bearing orthotopic xenografts demonstrated significant muscle wasting and atrophy-associated gene expression changes compared to controls. Further, despite the absence of adaptive immunity, splenic tissue from orthotopically engrafted mice demonstrated elevations in several pro-inflammatory cytokines associated with cancer cachexia, including TNFα, IL1β, IL6 and KC (murine IL8 homologue), when compared to controls. Therefore, data presented here support further investigation into the complexity of cancer cachexia in PC to identify potential targets for this debilitating syndrome.

2011-05-02

The Cancer Council Australia (CCA) Alcohol Working Group has prepared a position statement on alcohol use and cancer. The statement has been reviewed by external experts and endorsed by the CCA Board. Alcohol use is a cause of cancer. Any level of alcohol consumption increases the risk of developing an alcohol-related cancer; the level of risk increases in line with the level of consumption. It is estimated that 5070 cases of cancer (or 5% of all cancers) are attributable to long-term chronic use of alcohol each year in Australia. Together, smoking and alcohol have a synergistic effect on cancer risk, meaning the combined effects of use are significantly greater than the sum of individual risks. Alcohol use may contribute to weight (fat) gain, and greater body fatness is a convincing cause of cancers of the oesophagus, pancreas, bowel, endometrium, kidney and breast (in postmenopausal women). The existing evidence does not justify the promotion of alcohol use to prevent coronary heart disease, as the previously reported role of alcohol in reducing heart disease risk in light-to-moderate drinkers appears to have been overestimated. CCA recommends that to reduce their risk of cancer, people limit their consumption of alcohol, or better still avoid alcohol altogether. For individuals who choose to drink alcohol, CCA recommends that they drink only within the National Health and Medical Research Council guidelines for alcohol consumption.

Clinical Characteristics of Patients with Sporadic Colorectal Cancer and Primary Cancers of Other Organs

Full Text Available Most cancer patients often neglect the possibility of secondary cancer. Colorectal cancer (CRC is the third leading cause of cancer death in Taiwan. It is important to be aware of the clinical characteristics of double cancer in CRC patients for early diagnosis and treatment. We retrospectively analyzed 1,031 CRC patients who underwent surgical treatment at the Department of Surgery of Kaohsiung Medical University Hospital between January 1998 and December 2004. Among these patients, CRC was accompanied by cancer of other organs in 17 patients (1.65%, either synchronously or metachronously. Therefore, we describe our experience regarding the location of CRC, the clinical symptoms and signs of these patients, the TNM stage, histology, phase, association with other malignancies, interval between cancers and clinical outcomes. Of the 17 patients in whom CRC was accompanied by primary cancer of other organs, there were four synchronous and 13 metachronous multiple cancer patients. Our patient group comprised six men and 11 women with ages ranging from 47 to 88 years (median age, 66 years. The most common location of CRC was the sigmoid colon. Six gastric cancers (35.2% and six breast cancers (35.2% were associated with primary CRC. The remaining six second primary cancers were one lung cancer, one thyroid cancer, one cervical cancer, one ovarian cancer, one skin cancer, and one urinary bladder cancer. Of the 13 metachronous multiple cancer patients, eight patients developed subsequent CRC after primary cancers of other organs, whereas two patients developed a subsequent second primary cancer after CRC. The intervals between the development of metachronous multiple cancers ranged from 2 to 19 years. In this retrospective analysis, breast and gastric cancer patients were at increased risk of developing subsequent secondary CRC. Careful attention should always be paid to the possibility of secondary CRC in treating these cancer patients. Cancer

Ovarian Cancer Stroma: Pathophysiology and the Roles in Cancer Development

Directory of Open Access Journals (Sweden)

Mitsuko Furuya

2012-07-01

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

The risk of developing skin cancer is elevated among childhood cancer survivors (CCS), particularly among those treated with radiation. This survey study examined the skin cancer surveillance behaviors of 94 CCS. Approximately 48% of CCS had ever conducted skin self-examination (SSE) and 31% had ever received a physician skin examination. Rates of physician skin examination were 2.5 times higher among CCS treated with radiation compared to those without radiation. However, rates of SSEs did not differ based on treatment history. These findings highlight the need to promote skin cancer surveillance as an important aspect of CCS survivorship care. © 2015 Wiley Periodicals, Inc.

To determine whether buccal squamous cell carcinoma has worse overall survival (OS) and disease-specific survival (DSS) than cancers in the rest of the oral cavity. Retrospective analysis of a large population database. We began with a Kaplan-Meier analysis of OS and DSS for buccal versus nonbuccal tumors with unmatched data, followed by an analysis of cases matched for race, age at diagnosis, stage at diagnosis, and treatment modality. This was supported by a univariate Cox regression comparing buccal cancer to nonbuccal cancer, followed by a multivariate Cox regression that included all significant variables studied. With unmatched data, buccal cancer had significantly lesser OS and DSS values than cancers in the rest of the oral cavity (P cancer versus nonbuccal oral cancer were no longer significant. Univariate Cox regression models with respect to OS and DSS showed a significant difference between buccal cancer and nonbuccal cancer. However, with multivariate analysis, buccal hazard ratios for OS and DSS were not significant. With the largest series of buccal carcinoma to date, our study concludes that the OS and DSS of buccal cancer are similar to those of cancers in other oral cavity sites once age at diagnosis, tumor stage, treatment, and race are taken into consideration. The previously perceived poor prognosis of buccal carcinoma may be due to variations in tumor presentation, such as later stage and older patient age. 2b. © 2014 The American Laryngological, Rhinological and Otological Society, Inc.

Hauptmann, M; Fossa, S D; Stovall, M

2015-01-01

BACKGROUND: Abdominal radiotherapy for testicular cancer (TC) increases risk for second stomach cancer, although data on the radiation dose-response relationship are sparse. METHODS: In a cohort of 22,269 5-year TC survivors diagnosed during 1959-1987, doses to stomach subsites were estimated...... for 92 patients who developed stomach cancer and 180 matched controls. Chemotherapy details were recorded. Odds ratios (ORs) were estimated using logistic regression. RESULTS: Cumulative incidence of second primary stomach cancer was 1.45% at 30 years after TC diagnosis. The TC survivors who received...... radiotherapy (87 (95%) cases, 151 (84%) controls) had a 5.9-fold (95% confidence interval (CI) 1.7-20.7) increased risk of stomach cancer. Risk increased with increasing stomach dose (P-trend

Many veterans undergo cancer surgery outside of the Veterans Health Administration (VHA). We assessed to what extent these patients obtained care in the VHA before surgery. VHA-Medicare data, VHA administrative data, and Veterans Affairs Central Cancer Registry data. We identified patients aged ≥65 years in the VHA-Medicare cohort who underwent lung or colon cancer resection outside the VHA and assessed VHA visits in the year before surgery. Over 60% of patients in the VHA-Medicare cohort who received lung or colon cancer surgeries outside the VHA did not receive any care in VHA before surgery. Veterans' receipt of major cancer surgery outside the VHA probably reflects usual private sector care among veterans who are infrequent VHA users. © Health Research and Educational Trust.

Cancer-associated fibroblasts can promote the proliferation of colon cancer cells and growth of colon cancer tumors. Methods: We examined the role of cathelicidin in the development of colon cancer, using subcutaneous human HT-29 colon-cancer-cell-derived tumor model in nude mice and azoxymethane- and dextran sulfate-mediated colon cancer model in C57BL/6 mice. We also determined the indirect antitumoral mechanism of cathelicidin via the inhibition of epithelial–mesenchymal transition (EMT of colon cancer cells and fibroblast-supported colon cancer cell proliferation. Results: Intravenous administration of cathelicidin expressing adeno-associated virus significantly reduced the size of tumors, tumor-derived collagen expression, and tumor-derived fibroblast expression in HT-29-derived subcutaneous tumors in nude mice. Enema administration of the mouse cathelicidin peptide significantly reduced the size and number of colonic tumors in azoxymethane- and dextran sulfate-treated mice without inducing apoptosis in tumors and the adjacent normal colonic tissues. Cathelicidin inhibited the collagen expression and vimentin-positive fibroblast expression in colonic tumors. Cathelicidin did not directly affect HT-29 cell viability, but did significantly reduce tumor growth factor-ß1-induced EMT of colon cancer cells. Media conditioned by the

2018-04-01

Model systems for oral cancer research have progressed from tumor epithelial cell cultures to in vivo systems that mimic oral cancer genetics, pathological characteristics, and tumor-stroma interactions of oral cancer patients. In the era of cancer immunotherapy, it is imperative to use model systems to test oral cancer prevention and therapeutic interventions in the presence of an immune system and to discover mechanisms of stromal contributions to oral cancer carcinogenesis. Here, we review in vivo mouse model systems commonly used for studying oral cancer and discuss the impact these models are having in advancing basic mechanisms, chemoprevention, and therapeutic intervention of oral cancer while highlighting recent discoveries concerning the role of immune cells in oral cancer. Improvements to in vivo model systems that highly recapitulate human oral cancer hold the key to identifying features of oral cancer initiation, progression, and invasion as well as molecular and cellular targets for prevention, therapeutic response, and immunotherapy development.

ATM variants and cancer risk in breast cancer patients from Southern Finland

Aittomäki Kristiina

2006-08-01

Full Text Available Abstract Background Individuals heterozygous for germline ATM mutations have been reported to have an increased risk for breast cancer but the role for ATM genetic variants for breast cancer risk has remained unclear. Recently, a common ATM variant, ATMivs38 -8T>C in cis with the ATMex39 5557G>A (D1853N variant, was suggested to associate with bilateral breast cancer among familial breast cancer patients from Northern Finland. We have here evaluated the 5557G>A and ivs38-8T>C variants in an extensive case-control association analysis. We also aimed to investigate whether there are other ATM mutations or variants contributing to breast cancer risk in our population. Methods Two common ATM variants, 5557G>A and ivs38-8T>C, previously suggested to associate with bilateral breast cancer, were genotyped in an extensive set of 786 familial and 884 unselected breast cancer cases as well as 708 healthy controls. We also screened the entire coding region and exon-intron boundaries of the ATM gene in 47 familial breast cancer patients and constructed haplotypes of the patients. The identified variants were also evaluated for increased breast cancer risk among additional breast cancer cases and controls. Results Neither of the two common variants, 5557G>A and ivs38-8T>C, nor any haplotype containing them, was significantly associated with breast cancer risk, bilateral breast cancer or multiple primary cancers in any of the patient groups or subgoups. Three rare missense alterations and one intronic change were each found in only one patient of over 250 familial patients studied and not among controls. The fourth missense alteration studied further was found with closely similar frequencies in over 600 familial cases and controls. Conclusion Altogether, our results suggest very minor effect, if any, of ATM genetic variants on familial breast cancer in Southern Finland. Our results do not support association of the 5557G>A or ivs38-8T>C variant with

Triple negative breast cancers are an aggressive subtype of breast cancer with poor survival, but there remains little known about the etiological factors which promote its initiation and development. Commonly inherited breast cancer risk factors identified through genome wide association studies (GWAS) display heterogeneity of effect among breast cancer subtypes as defined by estrogen receptor (ER) and progesterone receptor (PR) status. In the Triple Negative Breast Cancer Consortium (TNBCC), 22 common breast cancer susceptibility variants were investigated in 2,980 Caucasian women with triple negative breast cancer and 4,978 healthy controls. We identified six single nucleotide polymorphisms (SNPs) significantly associated with risk of triple negative breast cancer, including rs2046210 (ESR1), rs12662670 (ESR1), rs3803662 (TOX3), rs999737 (RAD51L1), rs8170 (19p13.11) and rs8100241 (19p13.11). Together, our results provide convincing evidence of genetic susceptibility for triple negative breast cancer. PMID:21844186

The anti-cancer effects of metformin, the most widely used drug for type 2 diabetes, alone or in combination with ionizing radiation were studied with MCF-7 human breast cancer cells and FSaII mouse fibrosarcoma cells. Clinically achievable concentrations of metformin caused significant clonogenic death in cancer cells. Importantly, metformin was preferentially cytotoxic to cancer stem cells relative to non-cancer stem cells. Metformin increased the radiosensitivity of cancer cells in vitro, and significantly enhanced the radiation-induced growth delay of FSaII tumors (s.c.) in the legs of C3H mice. Both metformin and ionizing radiation activated AMPK leading to inactivation of mTOR and suppression of its downstream effectors such as S6K1 and 4EBP1, a crucial signaling pathway for proliferation and survival of cancer cells, in vitro as well as in the in vivo tumors. Conclusion: Metformin kills and radiosensitizes cancer cells and eradicates radioresistant cancer stem cells by activating AMPK and suppressing mTOR. PMID:22500211

Targeting lipid metabolism of cancer cells: A promising therapeutic strategy for cancer.

One of the most important metabolic hallmarks of cancer cells is deregulation of lipid metabolism. In addition, enhancing de novo fatty acid (FA) synthesis, increasing lipid uptake and lipolysis have also been considered as means of FA acquisition in cancer cells. FAs are involved in various aspects of tumourigenesis and tumour progression. Therefore, targeting lipid metabolism is a promising therapeutic strategy for human cancer. Recent studies have shown that reprogramming lipid metabolism plays important roles in providing energy, macromolecules for membrane synthesis, and lipid signals during cancer progression. Moreover, accumulation of lipid droplets in cancer cells acts as a pivotal adaptive response to harmful conditions. Here, we provide a brief review of the crucial roles of FA metabolism in cancer development, and place emphasis on FA origin, utilization and storage in cancer cells. Understanding the regulation of lipid metabolism in cancer cells has important implications for exploring a new therapeutic strategy for management and treatment of cancer.

Cancer as a Social Dysfunction - Why Cancer Research Needs New Thinking.

Science.gov (United States)

Pienta, Kenneth J; Axelrod, Robert

2018-05-21

The incidence and mortality for many cancers continues to rise. As such, critical action is needed on many fronts to reshape how a society thinks, discusses, and fights cancer especially as the population grows and ages. Cancer can be described as a broken social contract which requires different conceptual frameworks such as game theory. To this end, it is our hope that this perspective will catalyze a discussion to rethink the way we approach, communicate, and fund cancer research - thinking of cancer as a broken social contract is only one example. Importantly, this endeavor will require infusion of ideas from other fields such as physics, computational medicine, complexity science, agent-based modeling, sociology, and ecology all of which have the capacity to drive new insights into cancer biology and clinical medicine.

Breast Cancer Survivorship Care: Targeting a Colorectal Cancer Education Intervention

Directory of Open Access Journals (Sweden)

2015-08-01

Full Text Available Breast cancer survivors are at risk of developing a second primary cancer. Colorectal cancer (CRC is one of the leading second primary cancers, and it is often preventable. We developed a multi-component educational tool to inform and encourage women breast cancer survivors to engage in CRC screening. To assess the strengths and weakness of the tool and to improve the relevancy to the target audience, we convened four focus groups of women breast cancer survivors in Missouri. We also assessed the potential impact of the tool on the knowledge, attitudes, and beliefs regarding CRC and collected information on the barriers to CRC screening through pre- and post-focus groups’ questionnaires. A total of 43 women breast cancer survivors participated and provided very valuable suggestions on design and content to update the tool. Through the process and comparing pre- and post-focus group assessments, a significantly higher proportion of breast cancer survivors strongly agreed or agreed that CRC is preventable (78.6% vs. 96.9%, p = 0.02 and became aware that they were at a slightly increased risk for CRC (18.6% vs. 51.7%, p = 0.003. The most cited barrier was the complexity of preparation for colonoscopy.

This paper reviews the experience of the Workmen's Compensation Board of Ontario in identifying cases of cancer that could be attributed to occupational hazards. Workers' claims for compensation are allowed if there is reasonable medical evidence that their cancer was caused by exposure to risk factors associated with their occupation. Details of the types of cancers associated with specific carcinogens or fields of employment are discussed. About 50% of the cases were related to exposure in particular industrial operations that functioned for relatively brief periods. The number of deaths from cancer identified as being caused by occupational factors is compared with the total for cancer from all causes in Ontario during the period 1971 through 1975. Although all workers eligible for compensation may not have been identified, the data suggest that less than 1% is presently caused by occupational factors

Purpose Little is known about the breast cancer risk among childhood cancer survivors who did not receive chest radiotherapy. We sought to determine the magnitude of risk and associated risk factors for breast cancer among these women. Patients and Methods We evaluated cumulative breast cancer risk in 3,768 female childhood cancer survivors without a history of chest radiotherapy who were participants in the Childhood Cancer Survivor Study. Results With median follow up of 25.5 years (range, 8 to 39 years), 47 women developed breast cancer at a median age of 38.0 years (range, 22 to 47 years) and median of 24.0 years (range, 10 to 34 years) from primary cancer to breast cancer. A four-fold increased breast cancer risk (standardized incidence ratio [SIR] = 4.0; 95% CI, 3.0 to 5.3) was observed when compared with the general population. Risk was highest among sarcoma and leukemia survivors (SIR = 5.3; 95% CI, 3.6 to 7.8 and SIR = 4.1; 95% CI, 2.4 to 6.9, respectively). By the age of 45 years, the cumulative incidence of breast cancer in sarcoma and leukemia survivors was 5.8% (95% CI, 3.7 to 8.4) and 6.3% (95% CI, 3.0 to 11.3), respectively. No other primary cancer diagnosis was associated with an elevated risk. Alkylators and anthracyclines were associated with an increased breast cancer risk in a dose-dependent manner (P values from test for trend were both < .01). Conclusions Women not exposed to chest radiotherapy who survive childhood sarcoma or leukemia have an increased risk of breast cancer at a young age. The data suggest high-dose alkylator and anthracycline chemotherapy increase the risk of breast cancer. This may suggest a possible underlying gene-environment interaction that warrants further study. PMID:26700127

Socioeconomic, Rural-Urban, and Racial Inequalities in US Cancer Mortality: Part I-All Cancers and Lung Cancer and Part II-Colorectal, Prostate, Breast, and Cervical Cancers

International Nuclear Information System (INIS)

Singh, K. G.; Williams, S. D.

2011-01-01

We analyzed socioeconomic, rural-urban, and racial inequalities in US mortality from all cancers, lung, colorectal, prostate, breast, and cervical cancers. A deprivation index and rural-urban continuum were linked to the 2003-2007 county-level mortality data. Mortality rates and risk ratios were calculated for each socioeconomic, rural-urban, and racial group. Weighted linear regression yielded relative impacts of deprivation and rural-urban residence. Those in more deprived groups and rural areas had higher cancer mortality than more affluent and urban residents, with excess risk being marked for lung, colorectal, prostate, and cervical cancers. Deprivation and rural-urban continuum were independently related to cancer mortality, with deprivation showing stronger impacts. Socioeconomic inequalities existed for both whites and blacks, with blacks experiencing higher mortality from each cancer than whites within each deprivation group. Socioeconomic gradients in mortality were steeper in nonmetropolitanlitan areas. Mortality disparities may reflect inequalities in smoking and other cancer-risk factors, screening, and treatment

Cancer in numbers: Do preventive measures for colorectal cancer apply?

Full Text Available Abstract: Introduction: Cancer is a global problem as it will affect one in three men and one in four women during their lifetime. Colorectal cancer (CRC is the second most common cancer in men, after lung cancer, and is the second most common cancer in women after breast cancer. It is also the second leading cause of death in men and women separately, and is the second most common cause of cancer death if both genders are considered together. CRC accounts for approximately 10% of cancer deaths. Modifiable risk factors for CRC include smoking, physical inactivity, overweight and obesity, processed meat consumption, and excessive alcohol consumption. CRC screening programs are possible in economically developed countries. However, attention should be paid in the future to geographically populated areas and western lifestyles. Objective: To evaluate the effect on the incidence and mortality of diet and lifestyle of CRC and to determine the effect of secondary prevention through the early diagnosis of CRC. Methodology: An exhaustive search of Medline and Pubmed articles related to primary and secondary prevention of CRC is carried out and a meta-analysis of the same blocks is carried out. Results: 301 items related to primary or secondary prevention of CRC were recovered. Of these, 177 were considered valid in the meta-analysis: 12 in epidemiology, 56 in diet and lifestyle, and over 77 different projections for the early detection of CRC. Cancer is a global problem as it will affect one in three men and one in four women during their lifetime. There is no question of which environmental factors, probably diet, may explain these cancer rates. Excessive consumption of alcohol and high cholesterol diet are associated with a high risk of colon cancer. A diet low in folic acid and vitamin B6 is also associated with an increased risk of developing colon cancer with overexpression of p53. Eating pulses at least three times a week reduces the risk of

This paper is the report of 9 cases of anal and low rectal cancer following pelvic irradiation for cancer of uterus or cervix. This second cancer appears between the 10th and 20th year after radiotherapy, with a mean of 18,2 years. Its treatment can still be conservative for anal cancer but for low rectal tumor, abdominal resection is necessary. A statistical study has concluded that there is an excess risk for this group of patients, only for patients treated by radiotherapy for uterus cervix cancer. Those patients justify, endoscopic follow-up, especially after the 10th year with anterior rectal wall biopsies. With this attitude, these late complications should not offset the benefit of pelvic irradiation in the treatment of cancer of the uterus [fr

The thyroid is a butterfly-shaped gland that lies at the base of the throat in front of the windpipe. A member of the endocrine system, the thyroid secretes hormones to regulate heart rate, blood pressure, temperature, and metabolism. Cancer of the thyroid is the most common endocrine cancer and the eighth most common cancer in the U.S. An estimated 63,450 Americans will be diagnosed with thyroid cancer this year. The vast majority is of follicular cell origin, and the remaining cancer originates from parafollicular cells, so called medullary thyroid cancer.

The standard treatment for advanced laryngeal cancer has been shifting from total laryngectomy to various organ preservation therapies such as subtotal laryngectomy and chemoradiotherapy. Robbins showed remarkable results with RADPLAT, the superselective intra-arterial infusion of supradose cisplatin (150 mg/m 2 ), against advanced head and neck cancer. However, the volume of laryngeal cancer is smaller than those of the other sites of head and neck cancers, and so a swaller less dose of cisplatin could save advanced laryngeal cancer patients. It may be reasonable to treat these subtypes of laryngeal cancer with a different modality. Thirty-five patients with laryngeal cancer were treated with tri-weekly intra-arterial infusion of cisplatin (100 mg/body). A 200 times molar excessive amount of sodium thiosulfate was intravenously infused to reduce the toxicity of cisplatin. Ten of 16 patients with glottic cancer and 10 of 19 patients with supraglottic cancer were followed for more than 2 years. Larynx preservation rate of glottic and supraglottic cancer was 80% and 70%, and progression-free survival rate was 80% and 50%, respectively. Grade III and IV toxic events were less frequent than with RADPLAT or systemic administration of a similar dose of cisplatin. Glottic and supraglottic cancers show different clinical behaviors. Our protocol with less cisplatin than RADPLAT is especially effective for glottic cancer. (author)

Colorectal cancer (CRC) is the third most common cancer worldwide. This study was undertaken to evaluate survival outcomes and changes of disease outcomes of CRC patients over the last decades. A retrospective analysis of CRC patients in Christchurch was performed in four patient cohorts at 5 yearly intervals; 1993-94, 1998-99, 2004-05 and 2009. Data on cancer location, stage, surgical and oncological treatment and survival were collected. Univariate, multivariate and Kaplan-Meier survival analysis were performed. There were 1391 patients (355, 317, 419 and 300 per cohort), 1037 colon and 354 rectal cancers, respectively. For colon cancer, right-sided cancers appeared more common in later cohorts (P = 0.01). There was a significant decrease in the number of permanent stomas for colon cancer patients (P = 0.001). There was an analogous trend for rectal cancers (P = 0.075). More CRC patients with stage IV disease were treated surgically (P = 0.001) and colon cancer stages I and II tended to have increased survival if operated by a colorectal surgeon (P = 0.06). Oncology referrals have increased remarkably (P = 0.001). Overall 56% of patients were alive at 5 years however rectal cancer patients had significantly better 5-year survival than those with colon cancer (P rectal cancer patients have a better 5-year survival than colon cancer patients. The improved survival with early stage colon cancers operated on by specialist colorectal surgeons needs further exploration. © 2016 Royal Australasian College of Surgeons.

To overview the status of gynecologic cancer in Indonesia. Information regarding Indonesia obtained from World Bank Report and Statistical Yearbook of Indonesia 2007, epidemiological data obtained from Histopathological Data of Cancer in Indonesia 2002, Department of Health-Registry Body of Indonesian Specialist of Pathology Association-Indonesian Cancer Society; Various Hospitals in big Cities in Indonesia. 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.

Answer questions and earn CME/CNE New to the eighth edition of the American Joint Committee on Cancer (AJCC) Cancer Staging Manual for epithelial cancers of the esophagus and esophagogastric junction are separate, temporally related cancer classifications: 1) before treatment decision (clinical); 2) after esophagectomy alone (pathologic); and 3) after preresection therapy followed by esophagectomy (postneoadjuvant pathologic). The addition of clinical and postneoadjuvant pathologic stage groupings was driven by a lack of correspondence of survival, and thus prognosis, between both clinical and postneoadjuvant pathologic cancer categories (facts about the cancer) and pathologic categories. This was revealed by a machine-learning analysis of 6-continent data from the Worldwide Esophageal Cancer Collaboration, with consensus of the AJCC Upper GI Expert Panel. Survival is markedly affected by histopathologic cell type (squamous cell carcinoma and adenocarcinoma) in clinically and pathologically staged patients, requiring separate stage grouping for each cell type. However, postneoadjuvant pathologic stage groups are identical. For the future, more refined and granular data are needed. This requires: 1) more accurate clinical staging; 2) innovative solutions to pathologic staging challenges in endoscopically resected cancers; 3) integration of genomics into staging; and 4) precision cancer care with targeted therapy. It is the responsibility of the oncology team to accurately determine and record registry data, which requires eliminating both common errors and those related to incompleteness and inconsistency. Despite the new complexity of eighth edition staging of cancers of the esophagus and esophagogastric junction, these key concepts and new directions will facilitate precision cancer care.

Although the relationship between psyche and cancer dates back many centuries, and several studies were conducted on this topic during the last decades, the role of psychological factors in the development of cancer is still controversial. Although a lot of factors have been considered, attention has been focused mainly on stress, which has been evaluated also in experimental models. Generally, the results of case-control studies have been contradictory, and at times more stressfull events have been recorded in patients with benign tumors than in those with cancer. On the contrary, a higher incidence of stress-related cancers has not been documented in cohort studies. Since cancer is a genetic disease, it is difficult to hypothesize that psychological factors may permanently alter nucleotide sequence giving rise to multiple mutations needed for cancer development. At present, there is no sufficient evidence to affirm that psychological factors may contribute without doubt to cancer development.

Full Text Available Objectives: The purpose of this study is to report a case series of advanced cancer patients whose cancer pain was relieved by using autonomic nerve pharmacopuncture (ANP treatment. ANP is a subcutaneous injection therapy of mountain ginseng pharmacopuncture (MGP along the acupoints on the spine (Hua-Tuo-Jia-Ji-Xue; 0.5 cun lateral to the lower border of the spinous processes of vertebrae to enhance the immune system and to balance autonomic nerve function. Methods: Patients with three different types of cancer (gastric cancer, lung cancer, colon cancer with distant metastases with cancer pain were treated with ANP. 1 mL of MGP was injected into the bilateral Hua-Tuo-Jia-Ji-Xue on the T1-L5 sites (total 12 ─ 20 mL injection of each patient’s dorsum by using the principle of symptom differentiation. During ANP treatment, the visual analogue scale (VAS for pain was used to assess their levels of cancer pain; also, the dosage and the frequency of analgesic use were measured. Results: The cancer pain levels of all three patients improved with treatment using ANP. The VAS scores of the three patients decreased as the treatment progressed. The dosage and the frequency of analgesics also gradually decreased during the treatment period. Significantly, no related adverse events were found. Conclusion: ANP has shown benefit in controlling cancer pain for the three different types of cancer investigated in this study and in reducing the dosage and the frequency of analgesics. ANP is expected to be beneficial for reducing cancer pain and, thus, to be a promising new treatment for cancer pain.

Domesticating Cancer: An Evolutionary Strategy in the War on Cancer

Directory of Open Access Journals (Sweden)

Full Text Available Since cancer shares the same molecular machinery as the host, most therapeutic interventions that aim to target cancer would inadvertently also adversely affect the host. In addition, cancer continuously evolves, streamlining its host-derived genome for a new single-celled existence. In particular, short-term clinical success observed with most antineoplastic therapies directly relate to the fact that cancer is constantly evolving. However, the clonal evolution of cancer occasionally also render cancer cells uniquely susceptible to therapeutic interventions, as is exemplified by the clinical relevance of synthetic lethality. Synthetic lethality describes a situation where the simultaneous loss of function in two genes results in lethality, but where a loss of function in either single gene is tolerated. This observation suggests that the evolution of cancer, usually seen as a major clinical challenge, may also afford a key opportunity in lowering on-target toxicities accosted with chemotherapy. As an example, by subjecting cancer to specific selection regimes, cancer can in effect be placed on evolutionary trajectories leading to the development of “targetable” phenotypes such as synthetic lethal interactions. However, such a selection regime would have to overcome a range of obstacles such as on-target toxicity and the selection of an evolvable trait. Since the majority of cancer evolution manifests as a loss of function, we suggest that the induction of auxotrophic phenotypes (i.e., where an organism lose the ability to synthesize specific organic compounds required for growth and thus become dependent on it from dietary sources may represent an attractive therapeutic option. As an example, animals can obtain vitamin C either by de novo synthesis or from their diet. However, since the maintenance of synthetic pathways is costly, such pathways are often lost if no longer necessary, resulting in the organism being auxotrophic toward the

Despite a shift in the cancer culture and language used to describe individuals diagnosed with this disease, the extent to which individuals with cancer adopt a particular cancer-related identity and the impact of these identities in relation to their well-being is virtually unknown. Using a cross-sectional study design and a metropolitan tumor registry, a mail questionnaire to examine post-treatment quality of life was sent to prostate cancer (PCa) survivors. The sample consisted of 490 PCa survivors, ranging in age from 49-88 (M = 69.7; SD = 7.8), one to eight years after diagnosis. The outcome measure used in these analyses was the PANAS to assess positive and negative affect. The most frequently reported cancer-related identity was "someone who has had PCa" (57%). The least reported self view was "victim" (1%). Twenty-six percent of men self-identified as "survivors" while 6% thought of themselves as "cancer conquerors." Only 9% self-identified as a "patient." Multivariate analyses, adjusted for potential confounders, show respondents who identified themselves as "survivors" or "cancer conquerors" reported significantly higher scores on positive affect than men who self-identified as "patients" (p < .001). Although the majority of respondents identified themselves as "someone who has had cancer," identifying as a "survivor" or "someone who has conquered cancer" appears to have adaptive value for positive mood. Those who perceive themselves as survivors of prostate cancer may derive some benefit in well-being associated with this self assessment.
