  1. Research and comprehensive cancer control coalitions. (United States)

    Vinson, Cynthia; La Porta, Madeline; Todd, William; Palafox, Neal A; Wilson, Katherine M; Fairley, Temeika


    The goal of cancer control research is "to generate basic knowledge about how to monitor and change individual and collective behavior and to ensure that knowledge is translated into practice and policy rapidly, effectively, and efficiently" (Division of Cancer Control and Population Sciences in Cancer control framework and synthese rationale, 2010). Research activities span the cancer control continuum from prevention to early detection and diagnosis through treatment and survivorship (Division of Cancer Control and Population Sciences in Cancer control framework and synthese rationale, 2010). While significant advancements have been made in understanding, preventing and treating cancer in the past few decades, these benefits have yielded disproportionate results in cancer morbidity and mortality across various socioeconomic and racial/ethnic subgroups (Ozols et al in J Clin Oncol, 25(1):146-1622, 2007). It has been a high priority since the beginning of the Comprehensive Cancer Control (CCC) movement to utilize research in the development and implementation of cancer plans in the states, tribes and tribal organizations, territories and US Pacific Island Jurisdictions. Nevertheless, dissemination and implementation of research in coalition activities has been challenging for many programs. Lessons learned from programs and coalitions in the implementation and evaluation of CCC activities, as well as resources provided by national partners, can assist coalitions with the translation of research into practice.

    The Cancer Prevention and Control Research Network (CPCRN) is a thematic network dedicated to accelerating the adoption of evidence-based cancer prevention and control practices in communities by advancing dissemination and implementation science. Funded by the Centers for Disease Control and Prevention and National Cancer Institute, CPCRN has operated at two levels: Each participating network center conducts research projects with primarily local partners as well as multicenter collaborative research projects with state and national partners. Through multicenter collaboration, thematic networks leverage the expertise, resources, and partnerships of participating centers to conduct research projects collectively that might not be feasible individually. Although multicenter collaboration is often advocated, it is challenging to promote and assess. Using bibliometric network analysis and other graphical methods, this paper describes CPCRN's multicenter publication progression from 2004 to 2014. Searching PubMed, Scopus, and Web of Science in 2014 identified 249 peer-reviewed CPCRN publications involving two or more centers out of 6,534 total. The research and public health impact of these multicenter collaborative projects initiated by CPCRN during that 10-year period were then examined. CPCRN established numerous workgroups around topics such as: 2-1-1, training and technical assistance, colorectal cancer control, federally qualified health centers, cancer survivorship, and human papillomavirus. This paper discusses the challenges that arise in promoting multicenter collaboration and the strategies that CPCRN uses to address those challenges. The lessons learned should broadly interest those seeking to promote multisite collaboration to address public health problems, such as cancer prevention and control.

    Jillson, I A; Cousin, C E; Blancato, J K


    This article provides the findings of a survey of previous and current students in the UDC/GU-LCCC master's degree program. This master's degree program, Cancer Biology, Prevention, and Control is administered and taught jointly by faculty of a Minority Serving Institution, the University of the District of Columbia, and the Lombardi Comprehensive Cancer Center to incorporate the strengths of a community-based school with a research intensive medical center. The program was initiated in 2008 through agreements with both University administrations and funding from the National Cancer Institute. The master's degree program is 36 credits with a focus on coursework in biostatistics, epidemiology, tumor biology, cancer prevention, medical ethics, and cancer outreach program design. For two semesters during the second year, students work full-time with a faculty person on a laboratory or outreach project that is a requirement for graduation. Students are supported and encouraged to transition to a doctoral degree after they obtain the master's and many of them are currently in doctorate programs. Since the inception of the program, 45 students have initiated the course of study, 28 have completed the program, and 13 are currently enrolled in the program. The survey was designed to track the students in their current activities, as well as determine which courses, program enhancements, and research experiences were the least and most useful, and to discern students' perceptions of knowledge acquired on various aspects of Cancer Biology Prevention, and Control Master's Program. Thirty of the 35 individuals to whom email requests were sent responded to the survey, for a response rate of 85.7%. The results of this study will inform the strengthening of the Cancer Biology program by the Education Advisory Committee. They can also be used in the development of comparable collaborative master's degree programs designed to address the significant disparities in prevalence of

  7. The crossroads of GIS and health information: a workshop on developing a research agenda to improve cancer control

    Directory of Open Access Journals (Sweden)

    Lewis Denise


    Full Text Available Abstract Cancer control researchers seek to reduce the burden of cancer by studying interventions, their impact in defined populations, and the means by which they can be better used. The first step in cancer control is identifying where the cancer burden is elevated, which suggests locations where interventions are needed. Geographic information systems (GIS and other spatial analytic methods provide such a solution and thus can play a major role in cancer control. This report presents findings from a workshop held June 16–17, 2005, to bring together experts and stakeholders to address current issues in GIScience and cancer control. A broad range of areas of expertise and interest was represented, including epidemiology, geography, statistics, environmental health, social science, cancer control, cancer registry operations, and cancer advocacy. The goals of this workshop were to build consensus on important policy and research questions, identify roadblocks to future progress in this field, and provide recommendations to overcome these roadblocks.

    Hussain, Syed Akram; Sullivan, Richard


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

    AIM: In order to detect risk factors for esophageal cancer,a national research program was carried out during the Eighth Five-Year Plan (from 1991 to 1995). METHODS: Cixian County and Chichen County in Hebei Province were selected as the index and the control for the study fields with higher or lower incidence of esophagus cancer in China, respectively. In these areas, we investigated the pollution of three nitrogenous compounds in well water for drinking and the use of nitrogen fertilizer in farming. RESULTS: In well water, nitrate nitrogen, nitrite nitrogen and ammonia nitrogen were 8.77 mg/L, 0.014 mg/L and 0.009 mg/L in Cixian County in 1993, respectively. They were significantly higher than their levels (3.84 mg/L, 0.004 mg/L and 0.004 mg/L) in Chichen County (P<0.01, t=6.281,t=3.784,t=3.775). There was a trend that the nitrogenous compounds in well water increased from 1993 to 1996.The amount of nitrogen fertilizer used in farming was 787.6 kg per hectare land in Cixian County in 1991, significantly higher than 186 kg per hectare in Chichen County (t=9.603,P<0.001). CONCLUSION: These investigations indicate that the poilution of nitrogenous compounds in well water for drinking is closely related to the use of nitrogen fertlizer in farming, and there is a significantly positive correlation between the level of three nitrogenous compounds in well water and the mortality ofesophageal cancer (correlation coefficient =0.5992). We suggest that improvement of well system for drinking water quality should be an effective measure for esophageal cancer prevention and control in rural areas.

    Directory of Open Access Journals (Sweden)

    Kangolle Alfred CT


    Full Text Available Abstract Background Cancer is a rapidly increasing problem in developing countries. Access, quality and efficiency of cancer services in developing countries must be understood to advance effective cancer control programs. Health services research can provide insights into these areas. Discussion This article provides an overview of oncology health services in developing countries. We use selected examples from peer-reviewed literature in health services research and relevant publicly available documents. In spite of significant limitations in the available data, it is clear there are substantial barriers to access to cancer control in developing countries. This includes prevention, early detection, diagnosis/treatment and palliation. There are also substantial limitations in the quality of cancer control and a great need to improve economic efficiency. We describe how the application of health data may assist in optimizing (1 Structure: strengthening planning, collaboration, transparency, research development, education and capacity building. (2 Process: enabling follow-up, knowledge translation, patient safety and quality assurance. (3 Outcome: facilitating evaluation, monitoring and improvement of national cancer control efforts. There is currently limited data and capacity to use this data in developing countries for these purposes. Summary There is an urgent need to improve health services for cancer control in developing countries. Current resources and much-needed investments must be optimally managed. To achieve this, we would recommend investment in four key priorities: (1 Capacity building in oncology health services research, policy and planning relevant to developing countries. (2 Development of high-quality health data sources. (3 More oncology-related economic evaluations in developing countries. (4 Exploration of high-quality models of cancer control in developing countries. Meeting these needs will require national, regional and

    Richard R Love


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

  18. Bioprinting for cancer research. (United States)

    Knowlton, Stephanie; Onal, Sevgi; Yu, Chu Hsiang; Zhao, Jean J; Tasoglu, Savas


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

  19. Controlling micro- and nano-environment of tumor and stem cells for novel research and therapy of brain cancer (United States)

    Smith, Christopher Lloyd

    The use of modern technologies in cancer research has engendered a great deal of excitement. Many of these advanced approaches involve in-depth mathematical analyses of the inner working of cells, via genomic and proteomic analyses. However these techniques may not be ideal for the study of complex cell phenotypes and behaviors. This dissertation explores cancer and potential therapies through phenotypic analysis of cell behaviors, an alternative approach. We employ this experimental framework to study brain cancer (glioma), a particularly formidable example of this diverse ailment. Through the application of micro- and nanotechnology, we carefully control the surrounding environments of cells to understand their responses to various cues and to manipulate their behaviors. Subsequently we obtain clinically relevant information that allows better understanding of glioma, and enhancement of potential therapies. We first aim to address brain tumor dispersal, through analysis of cell migration. Utilizing nanometer-scale topographic models of the extracellular matrix, we study the migratory response of glioma cells to various stimuli in vitro. Second, we implement knowledge gained from these investigations to define characteristics of tumor progression in patients, and to develop treatments inhibiting cell migration. Next we use microfluidic and nanotopographic models to study the behaviors of stem cells in vitro. Here we attempt to improve their abilities to deliver therapeutic proteins to cancer, an innovative treatment approach. We analyze the multi-step process by which adipose-derived stem cells naturally home to tumor sites, and identify numerous environmental perturbations to enhance this behavior. Finally, we attempt to demonstrate that these cell culture-based manipulations can enhance the localization of adipose stem cells to glioma in vivo using animal models. Throughout this work we utilize environmental cues to analyze and induce particular behaviors in

  4. Comparison of Research Framing Preferences and Information Use of State Legislators and Advocates Involved in Cancer Control, United States, 2012–2013 (United States)

    Dodson, Elizabeth A.; Tabak, Rachel G.; Brownson, Ross C.


    Introduction Evidence-based policy plays an important role in prevention of cancer and other chronic diseases. The needs of actors involved in policy decision-making should inform knowledge translation strategies. This study examines the differences between state legislators and advocates in how they seek and use information and what their preferences are for how research information is framed. Methods We conducted a cross-sectional comparison of survey responses by US advocates (n = 77) and state legislators (n = 265) working on issues related to cancer control. Results Advocates differed significantly from legislators on all demographic characteristics. Advocates reported seeking and using information more frequently than legislators, though legislators used legislative research bureaus more often (0.45 point difference, P = .004). Both legislators and advocates prioritized the presentation and timeliness of research information similarly but reported different preferences for source (information bias, information relevance, delivery of information by trusted person) of research information. Several differences between advocates and legislators were modified by participant age. Conclusion Our study provides insights for development of knowledge translation strategies to enhance evidence-based policy making for cancer control that are tailored to state-level legislators and advocates. Additional research efforts should evaluate the effectiveness of such knowledge translation strategies, particularly among advocates. PMID:28152363

  4. Drosophila models for cancer research. (United States)

    Vidal, Marcos; Cagan, Ross L


    Drosophila is a model system for cancer research. Investigation with fruit flies has facilitated a number of important recent discoveries in the field: the hippo signaling pathway, which coordinates cell proliferation and death to achieve normal tissue size; 'social' behaviors of cells, including cell competition and apoptosis-induced compensatory proliferation, that help ensure normal tissue size; and a growing understanding of how oncogenes and tumor suppressors cooperate to achieve tumor growth and metastasis in situ. In the future, Drosophila models can be extended beyond basic research in the search for human therapeutics.

    Dai, Min; Bai, Yana; Pu, Hongquan; Cheng, Ning; Li, Haiyan; He, Jie


    Cancer control is a long-term work. Cancer research and intervention really need the support of cohort study. In the recent years, more and more cohort studies on cancer control were conducted in China along with the increased ability of scientific research in China. Since 2010, Cancer Hospital, Chinese Academy of Medical Sciences, collaborated with Lanzhou University and the Worker' s Hospital of Jinchuan Group Company Limited, have carried out a large-scale cohort study on cancer, which covered a population of more than 50 000 called " Jinchang cohort". Since 2012, a National Key Public Health Project, "cancer screening in urban China" , has been conducted in Jinchang, which strengthened the Jinchang cohort study. Based on the Jinchang cohort study, historical cohort study, cross-sectional study and prospective cohort study have been conducted, which would provide a lot of evidence for the cancer control in China.

  9. Adherence to the World Cancer Research Fund/American Institute for Cancer Research recommendations and breast cancer risk. (United States)

    Harris, Holly R; Bergkvist, Leif; Wolk, Alicja


    The World Cancer Research Fund/American Association for Cancer Research (WCRF/AICR) has published eight nutrition-related recommendations for the prevention of cancer. However, few prospective studies have examined these recommendations by breast cancer hormone receptor subtype and only one case-control study has included the dietary supplements recommendation in their evaluation. We investigated whether adherence to the WCRF/AICR cancer prevention recommendations was associated with breast cancer incidence, overall and by hormone receptor subtype, in the Swedish Mammography Cohort. Among 31,514 primarily postmenopausal women diet and lifestyle factors were assessed with a self-administered food frequency questionnaire. A score was constructed based on adherence to the recommendations for body fatness, physical activity, energy density, plant foods, animal foods, alcoholic drinks and dietary supplements (score range 0-7). Cox proportional hazard models were used to calculate hazard ratios (HRs) and 95% confidence intervals (95% CIs). During 15 years of follow-up 1,388 cases of breast cancer were identified. Women who met six to seven recommendations had a 51% decreased risk of breast cancer compared to women meeting only zero to two recommendations (95% CI = 0.35-0.70). The association between each additional recommendation met and breast cancer risk was strongest for the ER-positive/PR-positive subtype (HR = 0.86; 95% CI = 0.79-0.94), while for the ER-negative/PR-negative subtype the individual recommendations regarding plant and animal foods were most strongly associated with reduced risk. Our findings support that adherence to the WCRF/AICR recommendations reduces breast cancer risk in a population of primarily postmenopausal women. Promoting these recommendations to the public could help reduce breast cancer incidence.

  10. Towards meeting the research needs of Australian cancer consumers

    Directory of Open Access Journals (Sweden)

    Saunders Carla


    Full Text Available Abstract Background There is a growing amount of literature to support the view that active involvement in research by consumers, especially informed and networked consumers, benefits the quality and direction of research itself, the research process and, most importantly, people affected by cancer. Our exploratory project focuses on identifying their priorities and developing a process to assess the research needs of Australian cancer consumers which may be useful beyond the cancer scenario. Methods This project was consumer initiated, developed and implemented, with the assistance of a leading Australian cancer consumer advocacy group, Cancer Voices NSW (CVN. Such direct involvement is unusual and ensures that the priorities identified, and the process itself, are not influenced by other interests, regardless how well-intentioned they may be. The processes established, and data collection via a workshop, followed by a questionnaire to confirm and prioritise findings, and comparison with a similar UK exercise, are detailed in this paper. Results Needs across five topic areas reflecting cancer control domains (prevention and risk; screening and diagnosis; treatment; survivorship; and end of life were identified. Cancer consumers high priority research needs were found to be: earlier diagnosis of metastatic cancers; the extent of use of best practice palliative care guidelines; identifying barriers to cancer risk behaviour change; and environmental, nutrition and lifestyle risk factors for people with cancer. A process for identifying consumers’ research priorities was developed and applied; this may be useful for further investigation in this under-studied area. Conclusion The findings provide a model for developing a consumer derived research agenda in Australia which can be used to inform the strategic direction of cancer research. Consumers have been seeking a workable method to achieve this and have worked in collaboration with a major

  11. [China faces a challenge of breast cancer prevention and control]. (United States)

    Zhang, B N; Chen, W Q; Zhang, X; Qiao, Y L


    The incidence and mortality of breast cancer is in an increasing trend. In contrast to the global breast cancer situation, the prevention and control is challenging in China. Some suggestions are presented to the project of breast cancer prevention and control in China. Combining the global screening experiences with the epidemiological features of Chinese female breast cancer, aims to improve the population screening and early detection rate. Standardizing clinical diagnosis and treatment practice, aims to increase the efficacy and decrease the mortality. Intervening lifestyle and dietary behaviors, and intends to reduce risk exposure and incidence. Building national breast cancer registry provides preventive strategies. Great efforts should be made to carry out large sample multicenter clinical trails and translational research on the prevention and cotrol of breast cancer coordiated by health care service and science and technology administrations. Breast cancer prevention and control has a long way to go in China.

    Metastasis is the main reason for cancer-associated deaths and therapies are desperately needed to target the progression of cancer. Lysyl oxidase (LOX) plays a pivotal role in cancer progression, including metastasis, and is therefore is an attractive therapeutic target. In this review we will breakdown the process of cancer progression and the various roles that LOX plays has in the advancement of cancer. We will highlight why LOX is an exciting therapeutic target for the future.

  13. Aquatic invasive species: Lessons from cancer research (United States)

    Sepulveda, Adam; Ray, Andrew; Al-Chokhachy, Robert K.; Muhlfeld, Clint C.; Gresswell, Robert E.; Gross, Jackson A.; Kershner, Jeffrey L.


    Aquatic invasive species are disrupting ecosystems with increasing frequency. Successful control of these invasions has been rare: Biologists and managers have few tools for fighting aquatic invaders. In contrast, the medical community has long worked to develop tools for preventing and fighting cancer. Its successes are marked by a coordinated research approach with multiple steps: prevention, early detection, diagnosis, treatment options and rehabilitation. The authors discuss how these steps can be applied to aquatic invasive species, such as the American bullfrog (Lithobates catesbeianus), in the Northern Rocky Mountain region of the United States, to expedite tool development and implementation along with achievement of biodiversity conservation goals.

  14. Spatial Heterogeneity in Cancer Control Planning and Cancer Screening Behavior. (United States)

    Mobley, Lee R; Kuo, Tzy-Mey; Urato, Matthew; Subramanian, Sujha; Watson, Lisa; Anselin, Luc


    Each state is autonomous in its comprehensive cancer control (CCC) program, and considerable heterogeneity exists in the program plans. However, researchers often focus on the concept of nationally representative data and pool observations across states using regression analysis to come up with average effects when interpreting results. Due to considerable state autonomy and heterogeneity in various dimensions-including culture, politics, historical precedent, regulatory environment, and CCC efforts-it is important to examine states separately and to use geographic analysis to translate findings in place and time. We used 100 percent population data for Medicare-insured persons aged 65 or older and examined predictors of breast cancer (BC) and colorectal cancer (CRC) screening from 2001-2005. Examining BC and CRC screening behavior separately in each state, we performed 100 multilevel regressions. We summarize the state-specific findings of racial disparities in screening for either cancer in a single bivariate map of the 50 states, producing a separate map for African American and for Hispanic disparities in each state relative to whites. The maps serve to spatially translate the voluminous regression findings regarding statistically significant disparities between whites and minorities in cancer screening within states. Qualitative comparisons can be made of the states' disparity environments or for a state against a national benchmark using the bivariate maps. We find that African Americans in Michigan and Hispanics in New Jersey are significantly more likely than whites to utilize CRC screening and that Hispanics in 6 states are significantly and persistently more likely to utilize mammography than whites. We stress the importance of spatial translation research for informing and evaluating CCC activities within states and over time.

  16. Novel translational strategies in colorectal cancer research

    Institute of Scientific and Technical Information of China (English)


    Defining translational research is still a complex task. In oncology, translational research implies using our basic knowledge learnt from in vitro and in vivo experiments to directly improve diagnostic tools and therapeutic approaches in cancer patients. Moreover, the better understanding of human cancer and its use to design more reliable tumor models and more accurate experimental systems also has to be considered a good example of translational research. The identification and characterization of new molecular markers and the discovery of novel targeted therapies are two main goals in colorectal cancer translational research. However, the straightforward translation of basic research findings, specifically into colorectal cancer treatment and vice versa is still underway. In the present paper, a summarized view of some of the new available approaches on colorectal cancer translational research is provided. Pros and cons are discussed for every approach exposed.

    Cancer research in Africa will have a pivotal role in cancer control planning in this continent. However, environments (such as those in academic or clinical settings) with limited research infrastructure (laboratories, biorespositories, databases) coupled with inadequate funding and other resources have hampered African scientists from carrying out rigorous research. In September 2012, over 100 scientists with expertise in cancer research in Africa met in London to discuss the challenges in performing high-quality research, and to formulate the next steps for building sustainable, comprehensive and multi-disciplinary programmes relevant to Africa. This was the first meeting among five major organizations: the African Organisation for Research and Training in Africa (AORTIC), the Africa Oxford Cancer Foundation (AfrOx), and the National Cancer Institutes (NCI) of Brazil, France and the USA. This article summarizes the discussions and recommendations of this meeting, including the next steps required to create sustainable and impactful research programmes that will enable evidenced-based cancer control approaches and planning at the local, regional and national levels.

  2. Research on Dual Control

    Institute of Scientific and Technical Information of China (English)

    Duan Li; Fucai Qian; Peilin Fu


    This paper summarizes recent progress by the authors in developing two solution frameworks for dual control. The first solution framework considers a class of dual control problems where there exists a parameter uncertainty in the observation equation of the LQG problem. An analytical active dual control law is derived by a variance minimization approach. The issue of how to determine an optimal degree of active learning is then addressed, thus achieving an optimality for this class of dual control problems. The second solution framework considers a general class of discrete-time LQG problems with unknown parameters in both state and observation equations. The best possible (partial) closed-loop feedback control law is derived by exploring the future nominal posterior probabilities, thus taking into account the effect of future learning when constructing the optimal nominal dual control.

    The Northwest region of the United States contains extensive canal systems that transport water for hydropower generation. Nuisance plants, including algae, that grow in these systems reduce their hydraulic capacity through water displacement and increased surface friction. Most control methods are applied in an ad hoc fashion. The goal of this work is to develop cost-effective, environmentally sound, long-term management strategies to prevent and control nuisance algal growth. This paper reports on a multi-year study, performed in collaboration with the Pacific Gas & Electric Company, to investigate algal growth in their canal systems, and to evaluate various control methodologies. Three types of controls, including mechanical, biological and chemical treatment, were selected for testing and evaluation. As part of this study, water quality data were collected and algal communities were sampled from numerous stations throughout the distribution system at regular intervals. This study resulted in a more comprehensive understanding of conditions leading to the development of nuisance algal growth, a better informed selection of treatment plans, and improved evaluation of the effectiveness for the control strategies selected for testing.

  7. Cancer systems biology: signal processing for cancer research

    Institute of Scientific and Technical Information of China (English)

    Olli Yli-Harja; Antti Ylip(a)(a); Matti Nykter; Wei Zhang


    In this editorial we introduce the research paradigms of signal processing in the era of systems biology. Signal processing is a field of science traditionally focused on modeling electronic and communications systems, but recently it has turned to biological applications with astounding results. The essence of signal processing is to describe the natural world by mathematical models and then, based on these models, develop efficient computational tools for solving engineering problems. Here, we underline, with examples, the endless possibilities which arise when the battle-hardened tools of engineering are applied to solve the problems that have tormented cancer researchers. Based on this approach, a new field has emerged, called cancer systems biology. Despite its short history, cancer systems biology has already produced several success stories tackling previously impracticable problems. Perhaps most importantly, it has been accepted as an integral part of the major endeavors of cancer research, such as analyzing the genomic and epigenomic data produced by The Cancer Genome Atlas (TCGA) project. Finally, we show that signal processing and cancer research, two fields that are seemingly distant from each other, have merged into a field that is indeed more than the sum of its parts.

  11. Gastric cancer research in Mexico: a public health priority. (United States)

    Sampieri, Clara Luz; Mora, Mauricio


    This study aimed review studies conducted on Mexican patients diagnosed with gastric cancer and/or diseases associated with its development, in which at least one Mexican institute has participated, and to assess their contributions to the primary and secondary prevention of this disease. A search of the Medline database was conducted using the following keywords: gastric/stomach cancer, Mexico. Studies of the Mexican population were selected in which at least one Mexican Institute had participated and where the findings could support public policy proposals directed towards the primary or secondary prevention of gastric cancer. Of the 148 studies found in the Medline database, 100 were discarded and 48 were reviewed. According to the analysis presented, these studies were classified as: epidemiology of gastric cancer (5/48); risk factors and protectors relating to gastric cancer (9/48); relationship between Helicobacter pylori and pathologies associated with gastric cancer and the development of the disease (16/48); relationship between the Epstein-Barr virus and pathologies associated with gastric cancer and the development of the disease (3/48); molecular markers for the development of diseases associated with gastric cancer and gastric cancer (15/48). Mexico requires a program for the prevention and control of gastric cancer based on national health indicators. This should be produced by a multidisciplinary committee of experts who can propose actions that are relevant in the current national context. The few studies of gastric cancer conducted on the Mexican population in national institutes highlight the poor connection that currently exists between the scientific community and the health sector in terms of resolving this health issue. Public policies for health research should support projects with findings that can be translated into benefits for the population. This review serves to identify national research groups studying gastric cancer in the Mexican

    Ramirez, Amelie G; Gallion, Kipling J; Suarez, Lucina; Giachello, Aida L; Marti, Jose R; Medrano, Martha A; Pérez-Stable, Eliseo J; Talavera, Gregory A; Trapido, Edward J


    Although cancer is a leading cause of morbidity and premature death among Latinos, there is limited knowledge of cancer-related issues and priorities of greatest significance to the Latino population, the largest minority group in the nation. This information is vital in helping to guide Latino cancer research, training, and awareness efforts at national, regional, and local levels. To help identify cancer issues of greatest relevance to Latinos, Redes En Accion, The National Hispanic/Latino Cancer Network, a major network among the National Cancer Institute's Special Populations Networks, conducted a survey of 624 key opinion leaders from around the country. Respondents were asked to rank the three cancer sites most important to Latinos in their region and the five issues of greatest significance for this population's cancer prevention and control. Recommendations were prioritized for three specific areas: 1) research, 2) training and/or professional education, and 3) awareness and/or public education. Among cancers, breast carcinoma was ranked number one, followed in order by cervical and lung carcinomas. The issues of greatest significance to Latinos were 1) access to cancer screening and care, 2) tobacco use, 3) patient-doctor communication, 4) nutrition, and 5) risk communication. This survey solicited information from scientists, health care professionals, leaders of government agencies, professional and community-based organizations, and other stakeholders in Latino health. The results laid the foundation for a national Redes En Accion Latino cancer agenda, thus providing a useful tool for individuals and organizations engaged in cancer prevention and control efforts among the Hispanic-Latino population.

  15. Epigenetic research in cancer epidemiology: trends, opportunities, and challenges. (United States)

    Verma, Mukesh; Rogers, Scott; Divi, Rao L; Schully, Sheri D; Nelson, Stefanie; Joseph Su, L; Ross, Sharon A; Pilch, Susan; Winn, Deborah M; Khoury, Muin J


    Epigenetics is emerging as an important field in cancer epidemiology that promises to provide insights into gene regulation and facilitate cancer control throughout the cancer care continuum. Increasingly, investigators are incorporating epigenetic analysis into the studies of etiology and outcomes. To understand current progress and trends in the inclusion of epigenetics in cancer epidemiology, we evaluated the published literature and the National Cancer Institute (NCI)-supported research grant awards in this field to identify trends in epigenetics research. We present a summary of the epidemiologic studies in NCI's grant portfolio (from January 2005 through December 2012) and in the scientific literature published during the same period, irrespective of support from the NCI. Blood cells and tumor tissue were the most commonly used biospecimens in these studies, although buccal cells, cervical cells, sputum, and stool samples were also used. DNA methylation profiling was the focus of the majority of studies, but several studies also measured microRNA profiles. We illustrate here the current status of epidemiologic studies that are evaluating epigenetic changes in large populations. The incorporation of epigenomic assessments in cancer epidemiology studies has and is likely to continue to provide important insights into the field of cancer research.

  16. Phenomenology in pediatric cancer nursing research. (United States)

    Fochtman, Dianne


    What does it mean to have cancer as a child or adolescent? To understand this, researchers must study the illness from the child's point of view and listen to these children's descriptions of their "lived world." Phenomenology is a qualitative research methodology that can be used to discover and interpret meaning. To use phenomenology congruently, the philosophical background must be understood as well as the adaptation of the philosophical basis to research in the caring sciences. Only when clinicians truly understand the meaning of this illness to the child can they design nursing interventions to ease suffering and increase quality of life in children and adolescents with cancer.

    We studied the mechanism of radiation-induced apoptosis, the factors involved signaling, and the establishment of radiation-resistant cell lines in this study. During the TGF beta-stimulated epithelial mesenchymal transition(EMT), actin rearrangement occurred first and fibronectin matrix assembly followed. These two events were considered independent since cytochalasin-D did not inhibit TGF stimulated matrix assembly and fibronectin supplementation did not induce EMT. During EMT, alpha 5 beta 1 integrin and alpha v integrin have increased but MMP activation was not accompanied, which suggest that induction of extracellular matrix and activation of integrins may be main contributor for the EMT. Serum depriving induced apoptosis of HUVECs was prevented by vascular endothelial growth factor(VEGF) and PMA. The apoptosis prevention by VEGF and PMA were conformed by DNA fragmentation assay. The p53 expression level was down regulated by VEGF and PMA compared with serum deprived HUVECs. However, VEGF and PMA induces c-Myc expression level on these cells. We made the 5 radiation-resistant clones from breast, lung and cervical cancer cells. More than 70%, 100% and 50% increased resistance was detected in breast cancer cells, lung cancer cells, and cervical cells, respectively. We carried out differential display-PCR to clone the radiation-resistant genes. 9 out of 10 genes were analyzed their sequence.

    Zebrafish embryos can be obtained for research purposes in large numbers at low cost and embryos develop externally in limited space, making them highly suitable for high-throughput cancer studies and drug screens. Non-invasive live imaging of various processes within the larvae is possible due to their transparency during development, and a multitude of available fluorescent transgenic reporter lines.To perform high-throughput studies, handling large amounts of embryos and larvae is required. With such high number of individuals, even minute tasks may become time-consuming and arduous. In this chapter, an overview is given of the developments in the automation of various steps of large scale zebrafish cancer research for discovering important cancer pathways and drugs for the treatment of human disease. The focus lies on various tools developed for cancer cell implantation, embryo handling and sorting, microfluidic systems for imaging and drug treatment, and image acquisition and analysis. Examples will be given of employment of these technologies within the fields of toxicology research and cancer research.

    Cancer has become one of the most important public health issues than ever.It was reported that the incidence rate of cancer was 235.0/100 000 and the mortality rate was 144.3/100 000.In China,cases of deaths and new eases of cancer accounted for 26.9% and 21.8% of the world's total numbers.The seven papers included in this issue had elaborated the cancer morbidity,mortality and attributable years of life lost at national and provincial levels since 1990,as well as explored the risk factors and strategies on prevention and control of cancer.Information on burden of cancers is important in determining the target population on prevention and control of cancer,for the adequate arrangement of health resources and evaluation on the effects of intervention measures.%肿瘤已成为影响居民健康最重要的公共卫生问题之一.2015年中国居民营养与慢性病状况报告显示,中国居民癌症年发病率为235.0/10万,死亡率为144.3/10万,每年癌症死亡占全球的26.9%,癌症发病占全球的21.8%.本期“肿瘤疾病负担”栏目的7篇论著采用全球疾病负担的研究方法,对全国及各省自1990年以来主要癌症的发病、死亡和寿命损失加以阐述,并对影响肿瘤疾病负担的危险因素和防治策略进行深入分析,为确定肿瘤防控的目标人群,合理安排卫生资源以及干预措施的评价提供了重要依据.

  5. Institutional shared resources and translational cancer research

    Directory of Open Access Journals (Sweden)

    De Paoli Paolo


    Full Text Available Abstract The development and maintenance of adequate shared infrastructures is considered a major goal for academic centers promoting translational research programs. Among infrastructures favoring translational research, centralized facilities characterized by shared, multidisciplinary use of expensive laboratory instrumentation, or by complex computer hardware and software and/or by high professional skills are necessary to maintain or improve institutional scientific competitiveness. The success or failure of a shared resource program also depends on the choice of appropriate institutional policies and requires an effective institutional governance regarding decisions on staffing, existence and composition of advisory committees, policies and of defined mechanisms of reporting, budgeting and financial support of each resource. Shared Resources represent a widely diffused model to sustain cancer research; in fact, web sites from an impressive number of research Institutes and Universities in the U.S. contain pages dedicated to the SR that have been established in each Center, making a complete view of the situation impossible. However, a nation-wide overview of how Cancer Centers develop SR programs is available on the web site for NCI-designated Cancer Centers in the U.S., while in Europe, information is available for individual Cancer centers. This article will briefly summarize the institutional policies, the organizational needs, the characteristics, scientific aims, and future developments of SRs necessary to develop effective translational research programs in oncology. In fact, the physical build-up of SRs per se is not sufficient for the successful translation of biomedical research. Appropriate policies to improve the academic culture in collaboration, the availability of educational programs for translational investigators, the existence of administrative facilitations for translational research and an efficient organization

  6. A systematic review of studies evaluating diffusion and dissemination of selected cancer control interventions. (United States)

    Ellis, Peter; Robinson, Paula; Ciliska, Donna; Armour, Tanya; Brouwers, Melissa; O'Brien, Mary Ann; Sussman, Jonathan; Raina, Parminder


    With this review, the authors sought to determine what strategies have been evaluated (including the outcomes assessed) to disseminate cancer control interventions that promote the uptake of behavior change. Five topic areas along the cancer care continuum (smoking cessation, healthy diet, mammography, cervical cancer screening, and control of cancer pain) were selected to be representative. A systematic review was conducted of primary studies evaluating dissemination of a cancer control intervention. Thirty-one studies were identified that evaluated dissemination strategies in the 5 topic areas. No strong evidence currently exists to recommend any one dissemination strategy as effective in promoting the uptake of cancer control interventions. The authors conclude that there is a strong need for more research into dissemination of cancer control interventions. Future research should consider methodological issues such as the most appropriate study design and outcomes to be evaluated.

  10. Baldness and testicular cancer: the EPSAM case-control study. (United States)

    Moirano, G; Zugna, D; Grasso, C; Lista, P; Ciuffreda, L; Segnan, N; Merletti, F; Richiardi, L


    The etiology of testicular cancer is largely unexplained. Research has mainly focused on prenatal exposures, especially to sex hormones, while less attention has been paid to exposures that may act also postnatally. As baldness has been previously associated with testicular cancer risk we focused on baldness and body hairiness, which are both associated with androgen activity. We used data of the Postnatal Exposures and Male Health (EPSAM) study, a case-control study on testicular cancer conducted in the Province of Turin, Italy, involving cases diagnosed between 1997 and 2008. Information was collected using mailed questionnaires. Analyses included 255 cases and 459 controls. We calculated ORs and 95% CIs to estimate testicular cancer risk among those who developed baldness and among those with body hairiness. We found an inverse association between testicular cancer and baldness (OR: 0.67, 95% CI: 0.46-0.98) and body hairiness (OR: 0.78, 95% CI: 0.53-1.16), although the latter had wider CIs. The inverse association between baldness and testicular cancer is consistent with the results from previous studies. These results suggest that androgens activity may influence testicular cancer risk.

    Institute of Scientific and Technical Information of China (English)



    Field research and control work on liver cancer in Qidong during the past 15 years is reviewed and evaluated , and suggestion is made. Epidemic outline of liver cancer: Liver cancer incidence in Qidong has being increased since 1980' s.the rate ranged from 60 to 70 per 100 000 in 90' s.The dominant peak was seen at age of 50.Male: female ratio was over 3:1 .It appeared, hnwever. that the age specific incidence had a decrease tendency in recent years. Research advance and achievement : Cancer registration system in the field has been further consolidated .Tihe cancer incidence data of the periods 1983~1997 were published in Volumes Ⅵ, Ⅶ, and Ⅷ of" Cancer Incidence for Five Continents" edited by the lntemational Agency for Research on Cancer. A randomized controlled trial of screening for liver cancer has been conducted among high risk population, i.e., male HBsAg carriers in Qidong. This trial showed that the screening procedure was effective in advancing diagnosis and early treatment. However, it failed to demonstrate impact on mortality of the disease. Comprehensive measures including prevention of hepatitis B, control of aflatoxin, improvement of drinking water, and appropriate complement of selenium have being taken. Characteristics and evaluation: The field research net relies on a well-organized system: a network of health care, an administration of cancer control, a group of specialists and support medical workers, and a set of collaborative mechanism. Suggestion for development: Control for liver cancer on the spot should be stressed and fund increased for further research. Collalborative projects with academic institutions both home and abroad should be encouraged.Effective means of diagnosis and treatment for cancer should be developed. Education of fighting cancer and rehabilitation of the patients with cancer should be enhanced.%简要回顾及评估了启东15年的肝癌防治工作,并提出了建议。高发区流行

    Zhong, Jia-Ling; Huang, Chang-Zhi


    The ubiquitin proteasome system (UPS) is important for the degradation of proteins in eukaryotic cells. It is involved in nearly every cellular process and plays an important role in maintaining body homeostasis. An increasing body of evidence has linked alterations in the UPS to gastrointestinal malignancies, including esophageal, gastric and colorectal cancers. Here, we summarize the current literature detailing the involvement of the UPS in gastrointestinal cancer, highlighting its role in tumor occurrence and development, providing information for therapeutic targets research and anti-gastrointestinal tumor drug design.

  14. Translating basic research in cancer patient care

    Directory of Open Access Journals (Sweden)

    Marcello Maugeri-Saccà


    Full Text Available With the advent of molecular targeted therapies and the development of high-throughput biotechnologies, it has become evident that progress in cancer research is largely due to the creation of multidisciplinary teams able to plan clinical trials supported by appropriate molecular hypotheses. These efforts have culminated in the identification and validation of biomarkers predictive of response, as well as in the generation of more accurate prognostic tools. The identification of cancer stem cells has provided further insights into mechanisms of cancer, and many studies have tried to translate this biological notion into prognostic and predictive information. In this regard, new agents targeting key stemness-related pathways have entered the clinical development, and preliminary data suggested an encouraging antitumor activity.

  15. Microarray Applications in Cancer Research (United States)

    Kim, Il-Jin; Kang, Hio Chung


    DNA microarray technology permits simultaneous analysis of thousands of DNA sequences for genomic research and diagnostics applications. Microarray technology represents the most recent and exciting advance in the application of hybridization-based technology for biological sciences analysis. This review focuses on the classification (oligonucleotide vs. cDNA) and application (mutation-genotyping vs. gene expression) of microarrays. Oligonucleotide microarrays can be used both in mutation-genotyping and gene expression analysis, while cDNA microarrays can only be used in gene expression analysis. We review microarray mutation analysis, including examining the use of three oligonucleotide microarrays developed in our laboratory to determine mutations in RET, β-catenin and K-ras genes. We also discuss the use of the Affymetrix GeneChip in mutation analysis. We review microarray gene expression analysis, including the classifying of such studies into four categories: class comparison, class prediction, class discovery and identification of biomarkers.

  17. From Reductionism to Holism: Systems-oriented Approaches in Cancer Research. (United States)

    Kienle, Gunver; Kiene, Helmut


    Somatic mutation theory of cancer has directed cancer research during the last century. A deluge of information on cellular, molecular, and genetic behavior was uncovered, but so was a mind-numbing complexity that still challenges research and concepts, and expectations in the war on cancer have by and large not been fulfilled. A change of paradigm beyond reductionism has been called for, especially as research ubiquitously points at the importance of tissue, microenvironment, extracellular matrix, embryonic and morphogenetic fields, and fields of tissue maintenance and organization in the processes of carcinogenesis, cancer control, and cancer progression, as well as in the control of cellular and genetic behavior. Holistic, organismic systems concepts open new perspectives for cancer research and treatment, as well as general biological understanding.

    Research on occupational cancer epidemiology has been an important area of occupational health in Europe since the early studies were conducted in the United Kingdom in the 1950s and 1960s. During the last decade, occupational cancer research in Europe has gained an international dimension and become increasingly interdisciplinary in nature. At present, occupational exposures might be responsible for 13 to 18% of lung cancers, 2 to 10% of bladder cancers, and 2 to 8% of laryngeal cancers in E...

  20. The national database of hospital-based cancer registries: a nationwide infrastructure to support evidence-based cancer care and cancer control policy in Japan. (United States)

    Higashi, Takahiro; Nakamura, Fumiaki; Shibata, Akiko; Emori, Yoshiko; Nishimoto, Hiroshi


    Monitoring the current status of cancer care is essential for effective cancer control and high-quality cancer care. To address the information needs of patients and physicians in Japan, hospital-based cancer registries are operated in 397 hospitals designated as cancer care hospitals by the national government. These hospitals collect information on all cancer cases encountered in each hospital according to precisely defined coding rules. The Center for Cancer Control and Information Services at the National Cancer Center supports the management of the hospital-based cancer registry by providing training for tumor registrars and by developing and maintaining the standard software and continuing communication, which includes mailing lists, a customizable web site and site visits. Data from the cancer care hospitals are submitted annually to the Center, compiled, and distributed as the National Cancer Statistics Report. The report reveals the national profiles of patient characteristics, route to discovery, stage distribution, and first-course treatments of the five major cancers in Japan. A system designed to follow up on patient survival will soon be established. Findings from the analyses will reveal characteristics of designated cancer care hospitals nationwide and will show how characteristics of patients with cancer in Japan differ from those of patients with cancer in other countries. The database will provide an infrastructure for future clinical and health services research and will support quality measurement and improvement of cancer care. Researchers and policy-makers in Japan are encouraged to take advantage of this powerful tool to enhance cancer control and their clinical practice.

  1. Improving Cancer Care Through Nursing Research. (United States)

    Mayer, Deborah K


    Nursing research and nurse researchers have been an integral and significant part of the Oncology Nursing Society's (ONS's) history, as evidenced by the development of the Nursing Research Committee within a few years of ONS's establishment. Ruth McCorkle, PhD, RN, FAAN, was the committee's first chairperson in 1979. This was followed by the creation of the Advanced Nursing Research Special Interest Group in 1989 under the leadership of Jean Brown, PhD, RN, FAAN. ONS also began to recognize nurse researchers in 1994 by creating the annual ONS Distinguished Researcher Award to recognize the contributions of a member who has conducted or promoted research that has enhanced the science and practice of oncology nursing. The list of recipients and of their work is impressive and reflects the wide range of our practice areas (see for the recipient list). In addition, the ONS Foundation began funding research in 1981 and has distributed more than $24 million in research grants, research fellowships, and other scholarships, lectures, public education projects, and career development awards (ONS Foundation, 2015). And, in 2006, the Putting Evidence Into Practice resource was unveiled, which provides evidence-based intervention reviews for the 20 most common problems experienced by patients with cancer and their caregivers (www.ons

    Objective: To analyze the differences in effect of arterial interventional chemotherapy before radical gastrectomy for gastric cancer and simple radical gastrectomy for gastric cancer in treatment of advanced gastric cancer.Methods:A total of 86 cases of patients with advanced gastric cancer treated in our hospital were selected as research subjects and randomly divided into two groups, observation group received arterial interventional chemotherapy combined with radical gastrectomy for gastric cancer, control group received simple radical gastrectomy for gastric cancer, and then differences in prognosis-associated factors, MMP and Leptin contents as well as tumor marker and telomerase activity levels of two groups were compared.Results:Serum HER-2/neu ECD level of observation group was lower than that of control group, and serum DKK-1, TS and TP levels were higher than those of control group; at each point in time after treatment, serum CA72-4 and CA50 contents of observation group were lower than those of control group; intraoperative MMP-2, MMP-7, MMP-9 and Leptin levels in gastric cancer tissue of observation group were lower than those of control group; telomerase activity value in gastric cancer tissue of observation group after treatment was lower than that of control group, and both PGⅠ positive expression rate and PGⅠ/ PGⅡ ratio were higher than those of control group.Conclusion: Arterial interventional chemotherapy before radical gastrectomy for gastric cancer can lower tumor malignancy, promote the curative effect of radical gastrectomy for gastric cancer and improve long-term prognosis.

  3. Proteomics in epigenetics: new perspectives for cancer research. (United States)

    Bartke, Till; Borgel, Julie; DiMaggio, Peter A


    The involvement of epigenetic processes in the origin and progression of cancer is now widely appreciated. Consequently, targeting the enzymatic machinery that controls the epigenetic regulation of the genome has emerged as an attractive new strategy for therapeutic intervention. The development of epigenetic drugs requires a detailed knowledge of the processes that govern chromatin regulation. Over the recent years, mass spectrometry (MS) has become an indispensable tool in epigenetics research. In this review, we will give an overview of the applications of MS-based proteomics in studying various aspects of chromatin biology. We will focus on the use of MS in the discovery and mapping of histone modifications and how novel proteomic approaches are being utilized to identify and study chromatin-associated proteins and multi-subunit complexes. Finally, we will discuss the application of proteomic methods in the diagnosis and prognosis of cancer based on epigenetic biomarkers and comment on their future impact on cancer epigenetics.

  5. Modeling the Aneuploidy Control of Cancer

    Directory of Open Access Journals (Sweden)

    Wang Zhong


    Full Text Available Abstract Background Aneuploidy has long been recognized to be associated with cancer. A growing body of evidence suggests that tumorigenesis, the formation of new tumors, can be attributed to some extent to errors occurring at the mitotic checkpoint, a major cell cycle control mechanism that acts to prevent chromosome missegregation. However, so far no statistical model has been available quantify the role aneuploidy plays in determining cancer. Methods We develop a statistical model for testing the association between aneuploidy loci and cancer risk in a genome-wide association study. The model incorporates quantitative genetic principles into a mixture-model framework in which various genetic effects, including additive, dominant, imprinting, and their interactions, are estimated by implementing the EM algorithm. Results Under the new model, a series of hypotheses tests are formulated to explain the pattern of the genetic control of cancer through aneuploid loci. Simulation studies were performed to investigate the statistical behavior of the model. Conclusions The model will provide a tool for estimating the effects of genetic loci on aneuploidy abnormality in genome-wide studies of cancer cells.

    Johnson Kimberly


    Full Text Available Abstract Background Despite the pressing need for the creation of applications that facilitate the aggregation of clinical and molecular data, most current applications are proprietary and lack the necessary compliance with standards that would allow for cross-institutional data exchange. In line with its mission of accelerating research discoveries and improving patient outcomes by linking networks of researchers, physicians, and patients focused on cancer research, caBIG (cancer Biomedical Informatics Grid™ has sponsored the creation of the caTRIP (Cancer Translational Research Informatics Platform tool, with the purpose of aggregating clinical and molecular data in a repository that is user-friendly, easily accessible, as well as compliant with regulatory requirements of privacy and security. Results caTRIP has been developed as an N-tier architecture, with three primary tiers: domain services, the distributed query engine, and the graphical user interface, primarily making use of the caGrid infrastructure to ensure compatibility with other tools currently developed by caBIG. The application interface was designed so that users can construct queries using either the Simple Interface via drop-down menus or the Advanced Interface for more sophisticated searching strategies to using drag-and-drop. Furthermore, the application addresses the security concerns of authentication, authorization, and delegation, as well as an automated honest broker service for deidentifying data. Conclusion Currently being deployed at Duke University and a few other centers, we expect that caTRIP will make a significant contribution to further the development of translational research through the facilitation of its data exchange and storage processes.

  9. Control volume based hydrocephalus research (United States)

    Cohen, Benjamin; Voorhees, Abram; Wei, Timothy


    Hydrocephalus is a disease involving excess amounts of cerebral spinal fluid (CSF) in the brain. Recent research has shown correlations to pulsatility of blood flow through the brain. However, the problem to date has presented as too complex for much more than statistical analysis and understanding. This talk will highlight progress on developing a fundamental control volume approach to studying hydrocephalus. The specific goals are to select physiologically control volume(s), develop conservation equations along with the experimental capabilities to accurately quantify terms in those equations. To this end, an in vitro phantom is used as a simplified model of the human brain. The phantom's design consists of a rigid container filled with a compressible gel. The gel has a hollow spherical cavity representing a ventricle and a cylindrical passage representing the aquaducts. A computer controlled piston pump supplies pulsatile volume fluctuations into and out of the flow phantom. MRI is used to measure fluid velocity, and volume change as functions of time. Independent pressure measurements and flow rate measurements are used to calibrate the MRI data. These data are used as a framework for future work with live patients.

  11. Nurse's role in controlling cancer pain. (United States)

    Mahfudh, Salma Said


    Nurses spend more time with patients than any other member of the healthcare team. They play a critical, active and very important part in controlling cancer patients' pain and alleviating suffering. In controlling cancer pain the nurse needs to understand the psychological state of the cancer patient, cancer pain, cancer pain treatment, deleterious effects of unrelieved cancer pain and patient's socio cultural background. She needs to understand that there are two types of pain, nociceptive and neuropathic pains and that 80% of the cancer patients in pain could have 2 or more than 4 different pains at the same time. Nurses' role in controlling cancer pain include believing the patient, assessing pain, identifying the root of the problem, planning the care, administering medication, evaluating effectiveness, ensuring good pain control and individualizing treatment. It also includes nursing interventions such as giving tender nursing care, preventing pain, educating, advocating, communicating, comforting, supporting, and counseling the patient. The nurse must use both pharmacological and non pharmacological treatments to individualize treatment, know all the drugs that are used for the treatment of Cancer Pain, how these drugs relieve pain and what their side effects are. She must use the WHO guidelines to treat pain and must choose the right drug, right dose, given at the right times, with the right intervals and to the right patient. She must evaluate effectiveness of treatment, give PRN doses for breakthrough pain and recommend for specific changes. The role of the nurse is to anticipate the patient's pain needs, advocate for the patient for what feels appropriate for him within his cultural context and incorporate the patient's belief. The nurse can physically relieve pain by promoting comfort, support painful area, gentleness in handling the patient and use nursing treatments. The nurse can recommend physiotherapy, (TENS)/Acupuncture, Occupational therapy

    Presley, Carolyn J; Dotan, Efrat; Soto-Perez-de-Celis, Enrique; Jatoi, Aminah; Mohile, Supriya G; Won, Elizabeth; Alibhai, Shabbir; Kilari, Deepak; Harrison, Robert; Klepin, Heidi D; Wildes, Tanya M; Mustian, Karen; Demark-Wahnefried, Wendy


    Nutritional issues among older adults with cancer are an understudied area of research despite significant prognostic implications for treatment side effects, cancer-specific mortality, and overall survival. In May of 2015, the National Cancer Institute and the National Institute on Aging co-sponsored a conference focused on future directions in geriatric oncology research. Nutritional research among older adults with cancer was highlighted as a major area of concern as most nutritional cancer research has been conducted among younger adults, with limited evidence to guide the care of nutritional issues among older adults with cancer. Cancer diagnoses among older adults are increasing, and the care of the older adult with cancer is complicated due to multimorbidity, heterogeneous functional status, polypharmacy, deficits in cognitive and mental health, and several other non-cancer factors. Due to this complexity, nutritional needs are dynamic, multifaceted, and dependent on the clinical scenario. This manuscript outlines the proceedings of this conference including knowledge gaps and recommendations for future nutritional research among older adults with cancer. Three common clinical scenarios encountered by oncologists include (1) weight loss during anti-cancer therapy, (2) malnutrition during advanced disease, and (3) obesity during survivorship. In this manuscript, we provide a brief overview of relevant cancer literature within these three areas, knowledge gaps that exist, and recommendations for future research.

  13. Acidosis and Formaldehyde Secretion as a Possible Pathway of Cancer Pain and Options for Improved Cancer Pain Control. (United States)

    Hoang, Ba X; Shaw, D Graeme; Han, Bo; Fang, Josephine Y; Nimni, Marcel


    The prevalence of cancer pain in patients with cancer is high. The majority of efforts are spent on research in cancer treatment, but only a small fraction focuses on cancer pain. Pain in cancer patients, viewed predominantly as a secondary issue, is considered to be due to the destruction of tissues, compression of the nerves, inflammation, and secretion of biological mediators from the necrotic tumor mass. As a result, opioid drugs have remained as the primary pharmacological therapy for cancer pain for the past hundred years. This report reviews evidence that cancer pain may be produced by the metabolic effects of two byproducts of cancer-high acidity in the cancer microenvironment and the secretion of formaldehyde and its metabolites. We propose the research and development of therapeutic approaches for preemptive, short- and long-term management of cancer pain using available drugs or nutraceutical agents that can suppress or neutralize lactic acid production in combination with formaldehyde scavengers. We believe this approach may not only improve cancer pain control but may also enhance the quality of life for patients.

  14. [Making Decisions on the Resources for Cancer Control (United States)

    Gróf, Agnes


    We aim at modelling the strategic decision making process in case of devoting resources to a governmental cancer control program. We use a model based on the theory of Analytic Hierarchy Process. In this article we describe the characteristic features of such a decision making process and reveal the complexity of the problem underlying the decisions. A second article will present and discuss the results from the application of the AHP model. Interventions which are capable of decreasing the burden of cancer in a society need strategic approach. Decisions on interventions seem inevitable to be based on and balance between the priorities and the available resources. There is not much doubt about it that the reason for setting the priorities arises on the one hand from the scarcity of resources. On the other hand, priorities evolve on other bases, and are supposed to "guide" health policy makers devoting the scarce resources. In general, a strategic mode of thought has been based on assumptions, which, in case of cancer control enhance the necessity to assess information on cancer and cancer patients, and to understand the factors contributing towards better health. The capabilities of the NCCP achieving its aims by preventing the development of cancer diseases (primary prevention), by making use of the means of early detection and appropriate therapy (secondary prevention), and by providing modern (comprehensive) tertiary prevention are inevitably affected by the priorities. Health policy should assume a responsibility for enforcing certain priorities and should be aware of the long-term interest of the population. To solve the problem we restrict the model to a simple three level one, representing the goals, the criteria, and the alternatives of the resource allocation. We determine "decreasing the burden of cancer" as the overall goal. "Distributive justice" "cost-effectiveness", "human rights", "evidences", and "standpoints of a community" serve as criteria, while

  17. Epigenetic control of cancer by neuropeptides (United States)

    Galoian, Karina; Patel, Parthik


    Neuropeptides act as neurohormones, neurotransmitters and/or neuromodulators. Neuropeptides maintain physiological homeostasis and are paramount in molecular mechanisms of disease progression and regulation, including in cancer. Neuropeptides, by their definition, originate and are secreted from the neuronal cells, they are able to signal to neighboring cells or are released into the blood flow, if they act as neurohormones. The majority of neuropeptides exert their functions through G protein-coupled receptors, with certain exceptions. Although previous studies indicate that neuropeptides function in supporting proliferation of malignant cells in many types of solid tumor, the antitumorigenic action of the neuropeptides and their receptors, for example, in gastric cancers and chondrosarcoma, were also reported. It is known that epigenetically modified chromatin regulates molecular mechanisms involved in gene expression and malignant progression. The epigenetic modifications are genetically heritable, although they do not cause changes in DNA sequence. DNA methylation, histone modifications and miRNA expression are subject to those modifications. While there is substantial data on epigenetic regulation of neuropeptides, the epigenetic control of cancer by neuropeptides is considered to be uncharted territory. The aim of the current review is to describe the involvement of neuropeptides in the epigenetic machinery of cancer based on data obtained from our laboratory and from other authors.

  3. Differential network analysis in human cancer research. (United States)

    Gill, Ryan; Datta, Somnath; Datta, Susmita


    A complex disease like cancer is hardly caused by one gene or one protein singly. It is usually caused by the perturbation of the network formed by several genes or proteins. In the last decade several research teams have attempted to construct interaction maps of genes and proteins either experimentally or reverse engineer interaction maps using computational techniques. These networks were usually created under a certain condition such as an environmental condition, a particular disease, or a specific tissue type. Lately, however, there has been greater emphasis on finding the differential structure of the existing network topology under a novel condition or disease status to elucidate the perturbation in a biological system. In this review/tutorial article we briefly mention some of the research done in this area; we mainly illustrate the computational/statistical methods developed by our team in recent years for differential network analysis using publicly available gene expression data collected from a well known cancer study. This data includes a group of patients with acute lymphoblastic leukemia and a group with acute myeloid leukemia. In particular, we describe the statistical tests to detect the change in the network topology based on connectivity scores which measure the association or interaction between pairs of genes. The tests under various scores are applied to this data set to perform a differential network analysis on gene expression for human leukemia. We believe that, in the future, differential network analysis will be a standard way to view the changes in gene expression and protein expression data globally and these types of tests could be useful in analyzing the complex differential signatures.

    Cancer stem cells have been defined as cells within a tumor that possesses the capacity to self-renew and to cause the heterogeneous lineages of cancer cells that comprise the tumor. Experimental evidence showed that these highly tumorigenic cells might be responsible for initiation and progression of cancer into invasive and metastatic disease. Eradicating prostate cancer stem cells, the root of the problem, has been considered as a promising target in prostate cancer treatment to improve the prognosis for patients with advanced stages of the disease.

  15. What controls PTEN and what it controls (in prostate cancer)

    Institute of Scientific and Technical Information of China (English)

    Paramita M Ghosh


    The standard of care for metastatic prostate cancer (PCa) is androgen deprivation therapy since almost all PCa growth is initially reliant on the androgen receptor (AR).However,almost all patients develop resistance to this therapy within 18-24months,and current treatment for castration-resistant prostate cancer (CRPC) is extremely limited,despite the advent of new drugs that target the AR,such as ahiraterone and MDV3100.1 Multiple studies have associated the loss of phosphatase and tensin homolog deleted on chromosome 10(PTEN),a dual lipid and protein phosphatase that is frequently lost in prostate cancer,with the development of CRPC.2,3 Yet,multiple studies have shown that at least 20%-40%of primary PCa,which are almost always androgen sensitive,experience a loss of PTEN,4,5 while as many as 30% of CRPC tumors are PTEN-positive.6 The broad questions then facing researchers are:(i) How does PTEN loss cause CRPC?;(ii) What is the mechanism of CRPC development in PTEN+/+ tumors?;and (iii) How can CRPC tumors be inhibited in PTEN-null cells?Three new publications in recent times have come up with mechanisms that answer these questions.7-9 Two of these,both in Cancer Cell eadier this year,from the laboratories of Dr Charles Sawyers and Dr Hong Wu,address a novel negative feedback regulation between AR and PTEN,and all three,including the one from Dr Damu Tang,show that the loss of PTEN function is likely the first step towards the development of CRPC.

    Cancer is a major morbidity and mortality concern in Malaysia. Based on National Cancer Registry data, the Malaysian population is estimated to bear a cancer burden of about 40,000 new cases per year, and a cumulative lifetime risk of about 1:4. Cancer research in Malaysia has to consider needs relevant to our population, and resources constraints. Hence, funding bodies prioritise cancers of high prevalence, unique to our community and posing specific clinical problems. Cancer diagnosis is crucial to cancer management. While cancer diagnosis research largely aims at improvements in diagnostic information towards more appropriate therapy, it also impacts upon policy development and other areas of cancer management. The scope of cancer diagnosis upon which this paper is based, and their possible impact on other R&D areas, has been broadly categorized into: (1) identification of aetiological agents and their linkages to the development of precancer and cancer (impact on policy development, cancer prevention and treatment), (2) cancer biology and pathogenesis (impact on cancer prevention, treatment strategies and product development), (3) improvements in accuracy, sensitivity and specificity in cancer detection, monitoring and classification (impact on technology development) and (4) prognostic and predictive parameters (impact on treatment strategies). This paper is based on data collected by the Working Group on Cancer Diagnosis Research for the First National Conference on Cancer Research Coordination in April 2004. Data was collated from the databases of Institutions/Universities where the authors are employed, the Ministry of Science, Technology and Innovation (MOSTI) and targeted survey feedback from key cancer researchers. Under the 7th Malaysia Plan, 76 cancer projects were funded through the Intensified Research in Priority Areas (IRPA) scheme of MOSTI, amounting to almost RM15 million of grant money. 47(61.8%) of these projects were substantially in cancer

    The evidence against tobacco use is clear, incontrovertible, and convincing; so is the need for urgent and immediate action to stem the global tide of tobacco-related death and suffering and to improve public health. The American Association for Cancer Research makes an unequivocal call to all who are concerned about public health to take the following immediate steps:Increase the investment in tobacco-related research, commensurate with the enormous toll that tobacco use takes on human health, to provide the scientific evidence to drive the development of effective policies and treatments necessary to dramatically reduce tobacco use and attendant disease. Develop new evidence-based strategies to more effectively prevent the initiation of tobacco use, especially for youth and young adults. Promote the further development of evidence-based treatments for tobacco cessation, including individualized therapies, and ensure coverage of and access to evidence-based behavioral and pharmacological treatments. Develop evidence-based strategies for more effective public communication to prevent, reduce, and eliminate tobacco use and to guide health policies and clinical practice. Develop effective, evidence-based policies to reduce disparities across the tobacco continuum among social groups and developed and developing nations. Implement to the fullest extent existing evidence-based, systems-wide tobacco control programs to prevent initiation and foster cessation. Adapt and implement appropriate approaches to reduce the growing burden of tobacco use in the developing world. Enhance and coordinate surveillance efforts, both in the United States and globally, to monitor tobacco products, tobacco use, and tobacco-related disease, including tobacco use in oncology clinical trials. Establish a comprehensive, science-based regulatory framework to evaluate tobacco products and manufacturers' claims. Promote research that addresses the following: the potential harms of current and

    Huo, Guitao; Lu, Jianjun; Qu, Zhe; Lin, Zhi; Zhang, Di; Yang, Yanwei; Li, Bo


    The common fruit fly, Drosophila melanogaster, has been used to study human disease as a model organism for many years. Many basic biological, physiological, and neurological properties are conserved between mammals and fly. Moreover, Drosophila melanogaster has its unique advantage as a model organism. Recent studies showed that the high level of signaling pathway conservation in tumorigenesis between fly and human and its feasible genetic operation make fly an effective model for oncology research. Numerous research findings showed Drosophila melanogaster was an ideal model for studying the molecular mechanisms of tumorigenesis, invasion and metastasis. This review mainly focuses on the advantages of Drosophila melanogaster in cancer research, established models used for the research of specific cancers and prospective research direction of oncology. It is hoped that this paper can provide insight for cancer research and development of anti-cancer drugs.

    Full Text Available Background and objective Fast track surgery (FTS is a systematical method to accelerate the recovery of surgical patients by reducing the physical and mental trauma stress of them. The research is to investigate the feasibility of FTS application in lung cancer surgery. Methods A total of 80 cases of lung cancer patients with single leaf lobotomy resection were randomized into two groups. While the experimental group was treated with the conception of FTS, and the control group was treated with the traditional methods. The incident rate of post-operation pain degrees, telecasts, pleural effusion, the post-operation time stay in hospital time and the total cost during hospitalization in two groups were compared respectively. Results In FTS group: the VAS score of post-operation pain at 1 h, 6 h, 12 h, 24 h and 48 h all significantly decreased compared to the traditional therapy group. The incidence rate of telecast was 10.53%. The incidence rate of pleural effusion was 26.31%. The length of stay after operation was (4±1 d and the total cost was RMB 15 600±7 600. In the control group, the above values were 77.78%, 33.33%, 22.22%, (9±1 d, RMB 23 600±5 400, respectively. The post operation pain (VAS method of FTS group was remarkablely below the control group. There has significant difference of the incident rate of telecasts, stay time in hospital and the total cast in two groups (P < 0.05. No significant difference was observed in the incident rate of pleural effusion. Conclusion The new methods of FTS can apparently accelerates recovery after lung cancer resection, reduces complications, shorten timestay in hospital and cut down the total cost.

  4. Next generation distributed computing for cancer research. (United States)

    Agarwal, Pankaj; Owzar, Kouros


    Advances in next generation sequencing (NGS) and mass spectrometry (MS) technologies have provided many new opportunities and angles for extending the scope of translational cancer research while creating tremendous challenges in data management and analysis. The resulting informatics challenge is invariably not amenable to the use of traditional computing models. Recent advances in scalable computing and associated infrastructure, particularly distributed computing for Big Data, can provide solutions for addressing these challenges. In this review, the next generation of distributed computing technologies that can address these informatics problems is described from the perspective of three key components of a computational platform, namely computing, data storage and management, and networking. A broad overview of scalable computing is provided to set the context for a detailed description of Hadoop, a technology that is being rapidly adopted for large-scale distributed computing. A proof-of-concept Hadoop cluster, set up for performance benchmarking of NGS read alignment, is described as an example of how to work with Hadoop. Finally, Hadoop is compared with a number of other current technologies for distributed computing.

  6. [Research progression of translational medicine in gastric cancer]. (United States)

    Li, Maoran; Zhao, Gang; Zhu, Chunchao


    Gastric cancer is one of the most common malignant tumors which is a great threat to human health. In recent years, the reform of surgical mordalities and the optimization of radiation and chemotherapy is still far from reducing morbidity and mortality of gastric cancer. As a new research pattern, translational medicine has emerged in various clinical subjects, which leads to remarkable effects. In this paper, the definition and development of translational medicine, molecular markers and drug treatment of gastric cancer will be discussed and the feasibility of translational medicine in the treatment of gastric cancer will be explained. In our opinion, the intervention of translational medicine could change the current situation that scientific researches is severely disconnected with clinical practice and increase the detection rate of gastric cancer and the effective rate of adjuvant therapy after surgery to improve the prognosis of patients with gastric cancer.

The development of an effective ECI will require time, but this entity should be established immediately. As an initial step, coordination efforts should be directed towards the creation of a platform on translational research that could encompass (1) coordination between basic, clinical and epidemiological research; (2) formal agreements of co-operation between comprehensive cancer centres and basic research laboratories throughout Europe and (3) networking between funding bodies at the European level.The European Parliament and its instruments have had a major influence in cancer control in Europe, notably in tobacco control and in the implementation of effective population-based screening. To make further progress there is a need for novelty and innovation in cancer research and prevention in Europe, and having a platform such as the ECI, where those involved in all aspects of cancer research can meet, discuss and interact, is a decisive development for Europe.

    Zhu, Fei; Patumcharoenpol, Preecha; Zhang, Cheng; Yang, Yang; Chan, Jonathan; Meechai, Asawin; Vongsangnak, Wanwipa; Shen, Bairong


    Cancer is a malignant disease that has caused millions of human deaths. Its study has a long history of well over 100years. There have been an enormous number of publications on cancer research. This integrated but unstructured biomedical text is of great value for cancer diagnostics, treatment, and prevention. The immense body and rapid growth of biomedical text on cancer has led to the appearance of a large number of text mining techniques aimed at extracting novel knowledge from scientific text. Biomedical text mining on cancer research is computationally automatic and high-throughput in nature. However, it is error-prone due to the complexity of natural language processing. In this review, we introduce the basic concepts underlying text mining and examine some frequently used algorithms, tools, and data sets, as well as assessing how much these algorithms have been utilized. We then discuss the current state-of-the-art text mining applications in cancer research and we also provide some resources for cancer text mining. With the development of systems biology, researchers tend to understand complex biomedical systems from a systems biology viewpoint. Thus, the full utilization of text mining to facilitate cancer systems biology research is fast becoming a major concern. To address this issue, we describe the general workflow of text mining in cancer systems biology and each phase of the workflow. We hope that this review can (i) provide a useful overview of the current work of this field; (ii) help researchers to choose text mining tools and datasets; and (iii) highlight how to apply text mining to assist cancer systems biology research.

  14. Impact of biospecimens handling on biomarker research in breast cancer

    Directory of Open Access Journals (Sweden)

    Callari Maurizio


    Full Text Available Abstract Background Gene expression profiling is moving from the research setting to the practical clinical use. Gene signatures able to correctly identify high risk breast cancer patients as well as to predict response to treatment are currently under intense investigation. While technical issues dealing with RNA preparation, choice of array platforms, statistical analytical tools are taken into account, the tissue collection process is seldom considered. The time elapsed between surgical tissue removal and freezing of samples for biological characterizations is rarely well defined and/or recorded even for recently stored samples, despite the publications of standard operating procedures for biological sample collection for tissue banks. Methods Breast cancer samples from 11 patients were collected immediately after surgical removal and subdivided into aliquots. One was immediately frozen and the others were maintained at room temperature for respectively 2, 6 and 24 hrs. RNA was extracted and gene expression profile was determined using cDNA arrays. Phosphoprotein profiles were studied in parallel. Results Delayed freezing affected the RNA quality only in 3 samples, which were not subjected to gene profiling. In the 8 breast cancer cases with apparently intact RNA also in sample aliquots frozen at delayed times, 461 genes were modulated simply as a function of freezing timing. Some of these genes were included in gene signatures biologically and clinically relevant for breast cancer. Delayed freezing also affected detection of phosphoproteins, whose pattern may be crucial for clinical decision on target-directed drugs. Conclusion Time elapsed between surgery and freezing of samples appears to have a strong impact and should be considered as a mandatory variable to control for clinical implications of inadequate tissue handling.

  16. [Recommendations for cancer prevention of World Cancer Research Fund (WCRF): situational analysis for Chile]. (United States)

    Crovetto, Mirta; Uauy, Ricardo


    The main diet-related cancers include colorectal, lung, breast in (postmenopausal) women, stomach, esophagus, prostate and pancreas. After tobacco, obesity is the leading cause of cancer; it accounts for one third of all cancers. Cancer is associated with high total body fat, abdominal fat and weight gain in adult life. These are all potentially modifiable risk factors. Consumption of a "healthy diet" and living an "active life" can significantly reduce the risk of cancer. The aim of this study was to analyze the recommendations published by the World Cancer Research Fund (WCRF) and American Institute for Cancer Research (AICR) for the prevention of cancer in 2007. We compared the recommendations of Food, Nutrition and Physical Activity and the Prevention of Cancer: a global perspective", with the national situation in Chile, analyzing the national report on the prevalence of risk factors. Our main finding was that the pattern of consumption and lifestyles differ markedly from the WCRF recommendations: we observed an over consumption of sugary drinks and high intake of processed foods high in sodium and total fat and low consumption of legumes, vegetables, fruits high in antioxidants and fiber that protect from cancer. Chile has an increased cancer prevalence which is associated with poor quality diets, rising mean body mass index and a sedentary behavior. We recommend the strengthening programs to promote healthy diets and active living, in order to reduce cancer risk.

    Robert C. Millikan, DVM, PhD


    Full Text Available Introduction The goals of this study were to determine U.S. states with Comprehensive Cancer Control plans that include genomics in some capacity and to review successes with and barriers to implementation of genomics-related cancer control initiatives. Methods This study was conducted in two phases. Phase one included a content analysis of written state Comprehensive Cancer Control plans (n = 30 for terms related to genomics, or “genomic components” (n = 18. The second phase involved telephone interviews with the Comprehensive Cancer Control plan coordinators in states with plans that contained genomic components (n = 16. The interview was designed to gather more detailed information about the genomics-related initiatives within the state’s Comprehensive Cancer Control plan and the successes with and barriers to plan implementation, as defined by each state. Results Eighteen of the 30 Comprehensive Cancer Control plans analyzed contained genomics components. We noted a large variability among these 18 plans in the types of genomics components included. Nine (56% of the 16 states interviewed had begun to implement the genomics components in their plan. Most states emphasized educating health care providers and the public about the role of genomics in cancer control. Many states consider awareness of family history to be an important aspect of their Comprehensive Cancer Control plan. Approximately 67% of states with family history components in their plans had begun to implement these goals. Virtually all states reported they would benefit from additional training in cancer genetics and general public health genomics. Conclusion The number of states incorporating genomics into their Comprehensive Cancer Control plans is increasing. Family history is a public health application of genomics that could be implemented more fully into Comprehensive Cancer Control plans.

  20. Does cancer research focus on areas of importance to patients? (United States)

    Moorcraft, Sing Yu; Sangha, Amrit; Peckitt, Clare; Sanchez, Rodrigo; Lee, Martin; Pattison, Natalie; Wiseman, Theresa


    The majority of research ideas are proposed by clinicians or scientists and little is currently known about which areas of research patients feel are important. We performed a 4 week pilot patient survey at the Royal Marsden (a specialist cancer centre) to investigate patients' views on priorities for cancer research. A total of 780 patients completed the survey and the top research priorities were identified as: detection and prevention of cancer, scientific understanding, curative treatment and personalised treatment. The top research priorities were remarkably consistent across age, gender and a variety of tumour types. We believe that patients' views should be considered alongside those of clinicians and researchers when devising research proposals and strategies.

  2. Stem cell concepts renew cancer research. (United States)

    Dick, John E


    Although uncontrolled proliferation is a distinguishing property of a tumor as a whole, the individual cells that make up the tumor exhibit considerable variation in many properties, including morphology, proliferation kinetics, and the ability to initiate tumor growth in transplant assays. Understanding the molecular and cellular basis of this heterogeneity has important implications in the design of therapeutic strategies. The mechanistic basis of tumor heterogeneity has been uncertain; however, there is now strong evidence that cancer is a cellular hierarchy with cancer stem cells at the apex. This review provides a historical overview of the influence of hematology on the development of stem cell concepts and their linkage to cancer.

  3. Research Progress of Exosomes in Lung Cancer Diagnosis and Treatment

    Directory of Open Access Journals (Sweden)

    Hongbo ZOU


    Full Text Available As the leading cause of morbidity and cancer related-death worldwide, lung cancer has a serious threat to human health. Exosomes are nanoscale lipid membrane vesicles derived from multivesicles, which containing active biomolecules including proteins, lipids, nucleic acids and etc. Exosomes play important roles in lung cancer initiation and progression by promoting the formation of tumor microenvironment, enhancing tumor invasive and metastasis capability, leading to immunosuppression and resistance to chemoradiotherapy, and also have the application value in early diagnosis and treatment. This review summarizes the research progress of exosomes in tumor initiation and progression, and its roles in diagnosis and treatment of lung cancer.

  4. A Federated Network for Translational Cancer Research Using Clinical Data and Biospecimens. (United States)

    Jacobson, Rebecca S; Becich, Michael J; Bollag, Roni J; Chavan, Girish; Corrigan, Julia; Dhir, Rajiv; Feldman, Michael D; Gaudioso, Carmelo; Legowski, Elizabeth; Maihle, Nita J; Mitchell, Kevin; Murphy, Monica; Sakthivel, Mayurapriyan; Tseytlin, Eugene; Weaver, JoEllen


    Advances in cancer research and personalized medicine will require significant new bridging infrastructures, including more robust biorepositories that link human tissue to clinical phenotypes and outcomes. In order to meet that challenge, four cancer centers formed the Text Information Extraction System (TIES) Cancer Research Network, a federated network that facilitates data and biospecimen sharing among member institutions. Member sites can access pathology data that are de-identified and processed with the TIES natural language processing system, which creates a repository of rich phenotype data linked to clinical biospecimens. TIES incorporates multiple security and privacy best practices that, combined with legal agreements, network policies, and procedures, enable regulatory compliance. The TIES Cancer Research Network now provides integrated access to investigators at all member institutions, where multiple investigator-driven pilot projects are underway. Examples of federated search across the network illustrate the potential impact on translational research, particularly for studies involving rare cancers, rare phenotypes, and specific biologic behaviors. The network satisfies several key desiderata including local control of data and credentialing, inclusion of rich phenotype information, and applicability to diverse research objectives. The TIES Cancer Research Network presents a model for a national data and biospecimen network.

    Light, L; Tenney, J; Portnoy, B; Kessler, L; Rodgers, A B; Patterson, B; Mathews, O; Katz, E; Blair, J E; Evans, S K


    The growing evidence linking dietary patterns to the incidence and prevention of chronic disease has prompted a number of prominent health and scientific agencies to publish dietary guidelines for the public. Some dietary guidelines address specific diseases, such as cancer or heart disease; others focus on overall health promotion. This situation has created a demand for nutrition education and information programs for the public. Increasingly, supermarkets are seen as potential sites for effective consumer education. Eat for Health is a joint research study by the National Cancer Institute (NCI) and Giant Food Inc., a regional supermarket chain in the Washington-Baltimore area. The study's goal was to test the feasibility of supermarkets as a site for consumer nutrition education. Eat for Health's educational focus was diet and cancer control issues in the context of dietary patterns that promote health. Particular attention was paid to reduction of fat intake and increases in consumption of dietary fiber from grains, vegetables, and fruits. Analysis of program results is currently underway; data should be available in early 1990.

    S To provide evidences for exploiting tissue microarray (TMA) technology, we reviewed advantages and applications of TMA on tumor research. TMA has many advantages, including (1) section from TMA blocks can be utilized for the simultaneous analysis of up to 1,000 different tumors at DNA, RNA or protein level; (2) TMA is highly representative of their donor tissues; (3) TMA can improve conservation of tissue resources and experimental reagents, improve internal experimental control, and increase sample numbers per experiment, and can be used for large-scale, massively parallel in situ analysis; (4) TMA facilitates rapid translation of molecular discoveries to clinical applications. TMA has been applied to tumor research, such as glioma, breast tumor, lung cancer and so on. The development of novel biochip technologies has opened up new possibilities for the high-throughput molecular profiling of human tumors. Novel molecular markers emerging from high-throughput expression surveys could be analyzed on tumor TMA. It is anticipated that TMA, a new member of biochip, will soon become a widely used tool for all types of tissue-based research. TMA will lead to a significant acceleration of the transition of basic research findings into clinical applications.

  10. Lung cancer screening: did we really need a randomized controlled trial? (United States)

    Al-Ayoubi, Adnan M; Flores, Raja M


    Lung cancer is the leading cause of cancer mortality in the USA. Within the past decade, two large trials (the National Lung Screening Trial Research and the International Early Lung Cancer Action Program) confirmed a significant role for low-dose CT (LDCT) screening in identifying early stages of cancer leading to reduced mortality in high-risk patients. Given the evidence, the US Preventive Services Task Force issued a recommendation in favour of LDCT screening for high-risk individuals. Despite the strong support for LDCT among physicians who treat lung cancer and cumulative data demonstrating a survival benefit for screening and early detection, it took more than a decade for lung cancer screening to be embraced at the policy level. With many lives lost in the interim, did we really need a randomized controlled trial to make this decision?

    Brown, James A L; Ni Chonghaile, Triona; Matchett, Kyle B; Lynam-Lennon, Niamh; Kiely, Patrick A


    Insights distilled from integrating multiple big-data or "omic" datasets have revealed functional hierarchies of molecular networks driving tumorigenesis and modifiers of treatment response. Identifying these novel key regulatory and dysregulated elements is now informing personalized medicine. Crucially, although there are many advantages to this approach, there are several key considerations to address. Here, we examine how this big data-led approach is impacting many diverse areas of cancer research, through review of the key presentations given at the Irish Association for Cancer Research Meeting and importantly how the results may be applied to positively affect patient outcomes.

  12. Power Control Method for Research Reactor

    Energy Technology Data Exchange (ETDEWEB)

    Baang, Dane; Suh, Yongsuk; Park, Cheol [Korea Atomic Energy Research Institute, Daejeon (Korea, Republic of)


    Considering safety-oriented design concept and other control environment, we developed a simple controller that provides limiting function of power change- rate as well as fine tracking performance. The design result has been well-proven via simulation and actual application to a TRIGA-II type research reactor. The proposed controller is designed to track the PDM(Power Demand) from operator input as long as maintaining the power change rate lower than a certain value for stable reactor operation. A power control method for a TRIGA-II type research reactor has been designed, simulated, and applied to actual reactor. The control performance during commissioning test shows that the proposed controller provides fine control performance for various changes in reference values (PDM), even though there is large measurement noise from neutron detectors. The overshoot at low power level is acceptable in a sense of reactor operation.

  15. A comparison of cancer burden and research spending reveals discrepancies in the distribution of research funding

    Directory of Open Access Journals (Sweden)

    Carter Ashley JR


    Full Text Available Abstract Background Ideally, the distribution of research funding for different types of cancer should be equitable with respect to the societal burden each type of cancer imposes. These burdens can be estimated in a variety of ways; “Years of Life Lost” (YLL measures the severity of death in regard to the age it occurs, "Disability-Adjusted Life-Years" (DALY estimates the effects of non-lethal disabilities incurred by disease and economic metrics focus on the losses to tax revenue, productivity or direct medical expenses. We compared research funding from the National Cancer Institute (NCI to a variety of burden metrics for the most common types of cancer to identify mismatches between spending and societal burden. Methods Research funding levels were obtained from the NCI website and information for societal health and economic burdens were collected from government databases and published reports. We calculated the funding levels per unit burden for a wide range of different cancers and burden metrics and compared these values to identify discrepancies. Results Our analysis reveals a considerable mismatch between funding levels and burden. Some cancers are funded at levels far higher than their relative burden suggests (breast cancer, prostate cancer, and leukemia while other cancers appear underfunded (bladder, esophageal, liver, oral, pancreatic, stomach, and uterine cancers. Conclusions These discrepancies indicate that an improved method of health care research funding allocation should be investigated to better match funding levels to societal burden.

  16. Conducting Molecular Epidemiological Research in the Age of HIPAA: A Multi-Institutional Case-Control Study of Breast Cancer in African-American and European-American Women

    Directory of Open Access Journals (Sweden)

    Christine B. Ambrosone


    Full Text Available Breast cancer in African-American (AA women occurs at an earlier age than in European-American (EA women and is more likely to have aggressive features associated with poorer prognosis, such as high-grade and negative estrogen receptor (ER status. The mechanisms underlying these differences are unknown. To address this, we conducted a case-control study to evaluate risk factors for high-grade ER- disease in both AA and EA women. With the onset of the Health Insurance Portability and Accountability Act of 1996, creative measures were needed to adapt case ascertainment and contact procedures to this new environment of patient privacy. In this paper, we report on our approach to establishing a multicenter study of breast cancer in New York and New Jersey, provide preliminary distributions of demographic and pathologic characteristics among case and control participants by race, and contrast participation rates by approaches to case ascertainment, with discussion of strengths and weaknesses.

  17. Risk factors of Cancer Prostate A case control study. (United States)

    Kamel, Nahed M; Tayel, Eiman S; El Abbady, Ahmed A; Khashab, Sahar S


    The purpose of this study is to reveal the different risk factors related to this cancer particularly that there is no agreement about which factors affect the risk. A fishing expedition hospital based case control study was carried out. Cases and controls were identified from the Urology Department of Alexandria Main University Hospital, 2004. All cases diagnosed as having the tumor were included in the case series. For each case the second subject proved to have a negative pathological examination was included in the control group (50).Data collection was carried out blindly using a structured interview schedule. Analysis was applied using Chi-square test, Fisher exact and Student's t-test. Odds Ratios and 95% Confidence Intervals were calculated. Results indicated that regular consumption of sausages was greater among cases than controls (X(2)= 10.19, p= 0.001 and an odds ratio of 5.92 (CI: 1.69-25.99). Also more cases claimed consuming regularly butter and natural ghee than controls (X(2)= 5.47, p= 0.019). The estimate risk was as high as 2.79 (Cl: 1.07-7.33). However regular consumption of vegetables was more encountered among controls than cases (X(2) = 5.005, p= 0.025 where the odds ratio was 0.19 (Cl: 0.02-1.01). Moreover the multiple regression analysis confirmed the results obtained from univariate analysis. The consistency of results of current work as regards sausages and butter with several other research works can support the identification of these specific possible risk factors. Also other research workers pointed out to the protective effect of vegetables. However further research is needed to address other risk factors.

  18. Infections and cancer: debate about using vaccines as a cancer control tool. (United States)

    Mbulaiteye, Sam M; Buonaguro, Franco M


    In 2012, Infectious Agents and Cancer commissioned a thematic series collection of articles on Prevention of HPV related cancer. The articles have attracted wide interest and stimulated debate, including about the utility of vaccines in cancer control. The application of vaccines to cancer control fulfills a promise envisioned at the turn of the 20th century when remarkable experiments showed that some cancers were caused by infections. This suggested the possibility of applying infection-control strategies to cancer control. Vaccines represent the most practical cost-effective technology to prevent wide human suffering and death from many acute infectious diseases, such as small pox or polio. Hitherto applied to control of acute fatal infections, vaccines, if developed, might provide a potent way to control cancer. The articles in the HPV thematic series show success in developing and applying a vaccine against human papilloma virus (HPV). A vaccine is also available against hepatitis B virus (HBV), which causes liver cancer. These vaccines augment the tools available to control the associated cancers. Scientific endeavor continues for six other cancer-associated infections, mostly viruses. Not surprisingly, debate about the safety of vaccines targeting cancer has been triggered in the scientific community. Questions about safety have been raised for those populations where other means to control these cancers may be available. Although it is difficult to quantify risk from vaccines in individuals where other cancer control services exist, it is likely to be low. Vaccines are much safer today than before. Technological advancement in vaccine development and manufacture and improved regulatory review and efficient distribution have minimized substantially the risk for harm from vaccines. Formal and informal debate about the pros and cons of applying vaccines as a cancer control tools is ongoing in scientific journals and on the web. Infectious Agents and Cancer

  19. Nutrigenetics in cancer research--folate metabolism and colorectal cancer. (United States)

    Ulrich, Cornelia M


    The B vitamin folate is essential for one-carbon transfer reactions, including those related to the methylation of DNA or other substrates and nucleotide synthesis. Epidemiologic and experimental studies implicate low-folate intakes in elevated risk of colorectal neoplasia and suggest that biologic mechanisms underlying this relation include disturbances in DNA methylation patterns or adverse effects on DNA synthesis and repair. With the completion of the Human Genome Project, a vast amount of data on inherited genetic variability has become available. This genetic information can be used in studies of molecular epidemiology to provide information on multiple aspects of folate metabolism. First, studies linking polymorphisms in folate metabolism to an altered risk of cancer provide evidence for a causal link between this pathway and colorectal carcinogenesis. Second, studies on genetic characteristics can help clarify whether certain individuals may benefit from higher or lower intakes of folate or nutrients relevant to folate metabolism. Third, studies on genetic polymorphisms can generate hypotheses regarding possible biologic mechanisms that connect this pathway to carcinogenesis. Last, genetic variability in folate metabolism may predict survival after a cancer diagnosis, possibly via pharmacogenetic effects. To solve the puzzle of the folate-cancer relation, a transdisciplinary approach is needed that integrates knowledge from epidemiology, clinical studies, experimental nutrition, and mathematical modeling. This review illustrates knowledge that can be gained from molecular epidemiology in the context of nutrigenetics, and the questions that this approach can answer or raise.

  2. Two Archetypes of Motor Control Research. (United States)

    Latash, Mark L


    This reply to the Commentaries is focused on two archetypes of motor control research, one based on physics and physiology and the other based on control theory and ideas of neural computations. The former approach, represented by the equilibrium-point hypothesis, strives to discover the physical laws and salient physiological variables that make purposeful coordinated movements possible. The latter approach, represented by the ideas of internal models and optimal control, tries to apply methods of control developed for man-made inanimate systems to the human body. Specific issues related to control with subthreshold membrane depolarization, motor redundancy, and the idea of synergies are briefly discussed.

  3. Brain Cancer in Workers Employed at a Laboratory Research Facility.

    Directory of Open Access Journals (Sweden)

    James J Collins

    Full Text Available An earlier study of research facility workers found more brain cancer deaths than expected, but no workplace exposures were implicated.Adding four additional years of vital-status follow-up, we reassessed the risk of death from brain cancer in the same workforce, including 5,284 workers employed between 1963, when the facility opened, and 2007. We compared the work histories of the brain cancer decedents in relationship to when they died and their ages at death.As in most other studies of laboratory and research workers, we found low rates of total mortality, total cancers, accidents, suicides, and chronic conditions such as heart disease and diabetes. We found no new brain cancer deaths in the four years of additional follow-up. Our best estimate of the brain cancer standardized mortality ratio (SMR was 1.32 (95% confidence interval [95% CI] 0.66-2.37, but the SMR might have been as high as 1.69. Deaths from benign brain tumors and other non-malignant diseases of the nervous system were at or below expected levels.With the addition of four more years of follow-up and in the absence of any new brain cancers, the updated estimate of the risk of brain cancer death is smaller than in the original study. There was no consistent pattern among the work histories of decedents that indicated a common causative exposure.

It is ranked as the fourth leading cause of cancer-related deaths in the United States, and despite intensive basic and clinical research over the last few years, the survival benefit for the majority of patients with pancreatic cancer is still disappointing. Due to the absence of specific symptoms and the lack of early detection tests, pancreatic cancer is usually diagnosed at an advanced inoperrable stage and palliative chemotherapy with the purine analogue gemcitabine in combination with the targeted agent erlotinib, remains the mainstay method in the management of these patients. Therefore, there is an imperative need for new findings in the translational research field with prognostic, predictive and therapeutic value. In this paper we summarize five most interesting research abstracts as presented at the 2013 American Society of Clinical Oncology (ASCO Gastrointestinal Cancers Symposium. In particular, we focus on Abstract #141 which investigates the interaction between liver and pancreatic organ damage in patients with pancreatic cancer and the potential contribution of the patatin-like phospholipase domain containing 3 (PNPLA3 gene variation in pancreatic cancer development and on Abstract #149, in which, the prognostic and predictive role of SWI/SNF complex, a chromatin-remodeling complex, is examined. The key role of pharmacogenomics, in terms of predicting response and resistance to chemotherapy in pancreatic cancer patients, is analyzed in Abstract #142 and the contribution of circulating tumor cell detection in the early diagnosis of pancreatic cancer, allowing the avoidance of more invasive procedures like EUS-FNA, is discussed in Abstract #157. Lastly, in Abstract #164, the diagnostic utility of YKL-40 and IL-6 in pancreatic cancer patients is investigated.

    Following the Institute of Medicine's 2009 report on the national priorities for comparative effectiveness research (CER), funding for support of CER became available in 2009 through the American Recovery and Re-investment Act. The Centers for Disease Control and Prevention (CDC) received funding to enhance the infrastructure of population-based cancer registries and to expand registry data collection to support CER. The CDC established 10 specialized registries within the National Program of Cancer Registries (NPCR) to enhance data collection for all cancers and to address targeted CER questions, including the clinical use and prognostic value of specific biomarkers. The project also included a special focus on detailed first course of treatment for cancers of the breast, colon, and rectum, as well as chronic myeloid leukemia (CML) diagnosed in 2011. This paper describes the methodology and the work conducted by the CDC and the NPCR specialized registries in collecting data for the 4 special focused cancers, including the selection of additional data variables, development of data collection tools and software modifications, institutional review board approvals, training, collection of detailed first course of treatment, and quality assurance. It also presents the characteristics of the study population and discusses the strengths and limitations of using population-based cancer registries to support CER as well as the potential future role of population-based cancer registries in assessing the quality of patient care and cancer control.

    Objectives Investigate potential association between pioglitazone exposure and risk of prostate cancer. Research design and methods Nested, matched case–control study. UK primary care data (Clinical Practice Research Datalink (CPRD) GOLD) linked to inpatient (Hospital Episode Statistics (HES)) and cancer registry (National Cancer Information Network (NCIN)) data. English men aged ≥40 years diagnosed with type 2 diabetes mellitus, January 1, 2001 to January 5, 2015. Cases, with prostate cancer diagnosis, matched with up to 4 controls by age, cohort entry date and region. ORs for association of exposure to pioglitazone to incident prostate cancer, adjusted for potential confounders. Results From a cohort of 47 772 men with 243 923 person-years follow-up, 756 definite cases of prostate cancer were identified. Incidence was 309.9/100 000 person-years (95% CI 288.6 to 332.8). Pioglitazone use was not associated with prostate cancer risk; adjusted OR 0.759, 95% CI 0.502 to 1.148. Analyses showed no difference when possible cases, prostate cancer in CPRD GOLD only, included (adjusted OR 0.726, 95% CI 0.510 to 1.034). No association when adjusted for channeling bias (OR 0.778, 95% CI 0.511 to 1.184) or limited to an index date prior to July 1, 2011 (adjusted OR 0.508, 95% CI 0.294 to 0.879), despite prostate-specific antigen screening occurring more frequently among cases than controls (81.6% of 756 definite cases cf. 24.2% of 2942 controls (ppioglitazone use, increasing pioglitazone dose or increasing time since initiation. Conclusions In this real-world, nested matched case–control study, exposure to pioglitazone was not associated with increased risk of prostate cancer. PMID:28074141

    Full Text Available MicroRNAs (miRNA are important regulators of gene expression. They are involved in many physiological processes ensuring the cellular homeostasis of human cells. Alterations of the miRNA expression have increasingly been associated with pathophysiological changes of cancer cells making miRNAs currently to one of the most analyzed molecules in cancer research. Here we provide an overview of miRNAs in lung cancer. Specifically, we address biological functions of miRNAs in lung cancer cells, miRNA signatures generated from tumor tissue and from patients’ body fluids, the potential of miRNAs as diagnostic and prognostic biomarker for lung cancer, and its role as therapeutical target.

  13. Acupuncture Research at Memorial Sloan Kettering Cancer Center. (United States)

    Javdan, Bahar; Cassileth, Barrie


    Acupuncture may help treat specific cancer-related symptoms. Here, we summarize our clinical trials that sought to determine acupuncture's role in managing cancer-related symptoms. Trials have been conducted to determine acupuncture's ability to mitigate cancer-related symptoms including dyspnea, fatigue, xerostomia, lymphedema, hot flashes, postoperative ileus, pain and dysfunction after neck dissection, and postthoracotomy pain. Published studies indicate that acupuncture versus placebo acupuncture failed to reduce cancer-related dyspnea. Both true and sham acupuncture alleviated fatigue slightly, but no significant differences between groups emerged. Compared with sham acupuncture, our research showed that acupuncture significantly improved saliva production in patients with xerostomia and significantly reduced lymphedema patients' arm circumference in a pilot study. However, acupuncture failed to significantly reduce hot flashes and was no more successful than sham acupuncture in reducing postoperative ileus. Significant reductions in pain and dysfunction occurred in cancer patients after neck dissection. In a feasibility study, acupuncture was found to be acceptable to lung cancer patients and did not interfere with standard postoperative care. In summary, acupuncture is a potential candidate for the treatment of some important cancer-related symptoms. Large clinical trials and research to investigate mechanistic pathways are warranted.

  14. I wanted you to know: Breast cancer survivors' control of workplace communication about cancer. (United States)

    Robinson, Lynne; Kocum, Lucie; Loughlin, Catherine; Bryson, Lindsay; Dimoff, Jennifer K


    Of working women diagnosed with cancer, approximately one-third will have breast cancer. Communicating about their cancer plays an important role in their workplace experience. It is challenging but helpful in eliciting needed social support and accommodations. Fully understanding such communication experiences is important in order to facilitate the well-being and success of such women in their workplaces. A qualitative study permits a richer account of the details of these workplace communications, and a deeper understanding of how women manage the complex and multifaceted communication process. This study used thematic analysis of semistructured interviews from 19 women working full time at the time of their breast cancer diagnosis. We found 3 themes that encapsulated unfolding individual experiences, representing a complex interplay of challenges to maintaining a sense of personal control in workplace responses: challenges to control posed by the experience of sharing information in the workplace about the woman's cancer, women's very individual attempts to control how information about their cancer was shared, and the mixed responses of those who were told. The result was unique individual trajectories in which empathic responses tailored to the individual's needs and preferences were most helpful. These findings can provide guidance on managing cancer communication for survivors, and on how to best support and accommodate women workers with breast cancer, facilitating their ability to control how their cancer impacts their work experience. Our website ( provides a video, tip sheet, and other resources for facilitating supportive communication in the workplace.

    Cancer cells accommodate multiple genetic and epigenetic alterations that initially activate intrinsic (cell-autonomous) and extrinsic (immune-mediated) oncosuppressive mechanisms. Only once these barriers to oncogenesis have been overcome can malignant growth proceed unrestrained. Tetraploidization can contribute to oncogenesis because hyperploid cells are genomically unstable. We report that hyperploid cancer cells become immunogenic because of a constitutive endoplasmic reticulum stress response resulting in the aberrant cell surface exposure of calreticulin. Hyperploid, calreticulin-exposing cancer cells readily proliferated in immunodeficient mice and conserved their increased DNA content. In contrast, hyperploid cells injected into immunocompetent mice generated tumors only after a delay, and such tumors exhibited reduced DNA content, endoplasmic reticulum stress, and calreticulin exposure. Our results unveil an immunosurveillance system that imposes immunoselection against hyperploidy in carcinogen- and oncogene-induced cancers.

    Boussinesq M.


    Full Text Available Achievements obtained by the onchocerciasis control programmes should not lead to a relaxation in the biological research on Onchocerca volvulus. Issues such as the Loa loa-related postivermectin serious adverse events, the uncertainties as to whether onchocerciasis can be eliminated by ivermectin treatments, and the possible emergence of ivermectin-resistant O. volvulus populations should be addressed proactively. Doxycycline, moxidectin and emodepside appear to be promising as alternative drugs against onchocerciasis but support to researches in immunology and genomics should also be increased to develop new control tools, including both vaccines and macrofilaricidal drugs.

    Sørensen HT


    Full Text Available Henrik Toft Sørensen Editor in Chief Department of Clinical Epidemiology, Aarhus University Hospital, Aarhus, DenmarkCancer incidence increases with age, and about 43% of men and 30% of women aged 65 will develop cancer in their remaining lifetimes.1 The global population is rapidly aging, and by 2030 about 70% of cancer in, for example, the US, will be diagnosed in older patients.2 Fortunately, cancer survival has improved and 5-year survival exceeds 80% for many common cancers.3 As a result of these two complementary trends, the population of cancer survivors is growing at a rate of almost 2% per year.4As comorbidities accumulate with age, the number of patients with multimorbidity, ie, the coexistence of several chronic diseases, is increasing dramatically.5 In the US, about 80% of Medicare funds are spent on patients with four or more chronic conditions. Multimorbidity is associated with mortality, disability, low functional status, and risks of adverse drug events.6,7Clinical and epidemiological research on cancer prognosis has mainly focused on cancers in isolation, ignoring the impact of comorbidity and co-medication on the risk of complications and mortality. Comorbidity is a medical condition that exists at the time of diagnosis of the cancer or later, but which is not a consequence of the cancer itself.8Comorbidity is common in cancer patients, who often have adverse lifestyle factors such as alcohol use, obesity, and smoking, which cause other chronic diseases. Thus, many cancer patients have chronic disorders such as chronic obstructive pulmonary disease, acute myocardial infarction, stroke, metabolic syndrome, and osteoporosis.9–13 With the growing population of elderly patients with cancer and other chronic diseases, modern medicine will need to address multiple medical problems at once, focusing on mortality, treatment complications, quality of life, and implications for screening.7,14 In this issue of Clinical Epidemiology

  5. Health psychology and translational genomic research: bringing innovation to cancer-related behavioral interventions. (United States)

    McBride, Colleen M; Birmingham, Wendy C; Kinney, Anita Y


    The past decade has witnessed rapid advances in human genome sequencing technology and in the understanding of the role of genetic and epigenetic alterations in cancer development. These advances have raised hopes that such knowledge could lead to improvements in behavioral risk reduction interventions, tailored screening recommendations, and treatment matching that together could accelerate the war on cancer. Despite this optimism, translation of genomic discovery for clinical and public health applications has moved relatively slowly. To date, health psychologists and the behavioral sciences generally have played a very limited role in translation research. In this report we discuss what we mean by genomic translational research and consider the social forces that have slowed translational research, including normative assumptions that translation research must occur downstream of basic science, thus relegating health psychology and other behavioral sciences to a distal role. We then outline two broad priority areas in cancer prevention, detection, and treatment where evidence will be needed to guide evaluation and implementation of personalized genomics: (a) effective communication, to broaden dissemination of genomic discovery, including patient-provider communication and familial communication, and (b) the need to improve the motivational impact of behavior change interventions, including those aimed at altering lifestyle choices and those focusing on decision making regarding targeted cancer treatments and chemopreventive adherence. We further discuss the role that health psychologists can play in interdisciplinary teams to shape translational research priorities and to evaluate the utility of emerging genomic discoveries for cancer prevention and control.

  6. Public figure announcements about cancer and opportunities for cancer communication: a review and research agenda. (United States)

    Noar, Seth M; Willoughby, Jessica Fitts; Myrick, Jessica Gall; Brown, Jennifer


    Announcements by public figures and celebrities about cancer diagnosis or death represent significant events in public life. But what are the substantive effects of such events, if any? The purpose of this article is to systematically review studies that examined the impact of public figure cancer announcements on cancer-oriented outcomes. Using comprehensive search procedures, we identified k = 19 studies that examined 11 distinct public figures. The most commonly studied public figures were Jade Goody, Kylie Minogue, Nancy Reagan, and Steve Jobs, with the most common cancers studied being breast (53%), cervical (21%), and pancreatic (21%) cancer. Most studies assessed multiple outcome variables, including behavioral outcomes (k = 15), media coverage (k = 10), information seeking (k = 8), cancer incidence (k = 3), and interpersonal communication (k = 2). Results fairly consistently indicated that cancer announcements from public figures had meaningful effects on many, if not most, of these outcome variables. While such events essentially act as naturally occurring interventions, the effects tend to be relatively short term. Gaps in this literature include few contemporary studies of high-profile public figures in the United States and a general lack of theory-based research. Directions for future research as well as implications for cancer communication and prevention are discussed.

    Full Text Available Background: Sexual dysfunction in breast cancer patients is considered as a common and distressing problem. Considering the increasing number of breast cancer survivors living for longer periods of time with the disease and the importance of their quality of life, we conducted the present study to compare the sexual functioning in breast cancer patients with their healthy counterparts.Methods: In this case-control study, breast cancer patients who completed their treatment protocol and were followed up for at least six months were included. The controls were healthy women with normal clinical breast examinations. All subjects filled-in the Persian version of Female Sexual Function Index questionnaire.Results: A total of 165 subjects including 71 breast cancer patients and 94 healthy women were studied. The frequency of sexual dysfunction in cases and controls was 52.6% and 47.4%, respectively (P = 0.09. There were no significant differences between the two groups regarding domain scores, except for vaginal lubrication (P = 0.045. Logistic regression analysis indicated that significant determinants of sexual dysfunction in breast cancer group was patients' age (OR = 4.0, 95%CI: 1.3 – 11.5, P = 0.01 and age of the spouse (OR= 9.8, 95% CI: 1.8-51.9, P= 0.007, while in controls, only emotional relationship with the husband was the significant predictive factor (OR = 6.3, 95%CI: 1.9 – 20.5, P = 0.002.Conclusions: Our findings indicated that sexual dysfunction is prevalent in Iranian women regardless of their physical health status. The frequency of vaginal dryness in breast cancer patients was significantly higher than controls. Age of the patient and the spouse (>40 were the only significant predictors of sexual dysfunction among women with breast cancer. Preventive strategies, sexual education and access to effective treatment should be planned in supportive care of breast cancer patients.

  8. A survey of etiologic hypotheses among testicular cancer researchers. (United States)

    Stang, A; Trabert, B; Rusner, C; Poole, C; Almstrup, K; Rajpert-De Meyts, E; McGlynn, K A


    Basic research results can provide new ideas and hypotheses to be examined in epidemiological studies. We conducted a survey among testicular cancer researchers on hypotheses concerning the etiology of this malignancy. All researchers on the mailing list of Copenhagen Testis Cancer Workshops and corresponding authors of PubMed-indexed articles identified by the search term 'testicular cancer' and published within 10 years (in total 2750 recipients) were invited to respond to an e-mail-based survey. Participants of the 8th Copenhagen Testis Cancer Workshop in May 2014 were subsequently asked to rate the plausibility of the suggested etiologic hypotheses on a scale of 1 (very implausible) to 10 (very plausible). This report describes the methodology of the survey, the score distributions by individual hypotheses, hypothesis group, and the participants' major research fields, and discuss the hypotheses that scored as most plausible. We also present plans for improving the survey that may be repeated at a next international meeting of experts in testicular cancer. Overall 52 of 99 (53%) registered participants of the 8th Copenhagen Testis Cancer Workshop submitted the plausibility rating form. Fourteen of 27 hypotheses were related to exposures during pregnancy. Hypotheses with the highest mean plausibility ratings were either related to pre-natal exposures or exposures that might have an effect during pregnancy and in post-natal life. The results of the survey may be helpful for triggering more specific etiologic hypotheses that include factors related to endocrine disruption, DNA damage, inflammation, and nutrition during pregnancy. The survey results may stimulate a multidisciplinary discussion about new etiologic hypotheses of testicular cancer.

  15. Cancer specificity of promoters of the genes controlling cell proliferation. (United States)

    Kashkin, Kirill; Chernov, Igor; Stukacheva, Elena; Monastyrskaya, Galina; Uspenskaya, Natalya; Kopantzev, Eugene; Sverdlov, Eugene


    Violation of proliferation control is a common feature of cancer cells. We put forward the hypothesis that promoters of genes involved in the control of cell proliferation should possess intrinsic cancer specific activity. We cloned promoter regions of CDC6, POLD1, CKS1B, MCM2, and PLK1 genes into pGL3 reporter vector and studied their ability to drive heterologous gene expression in transfected cancer cells of different origin and in normal human fibroblasts. Each promoter was cloned in short (335-800 bp) and long (up to 2.3 kb) variants to cover probable location of core and whole promoter regulatory elements. Cloned promoters were significantly more active in cancer cells than in normal fibroblasts that may indicate their cancer specificity. Both versions of CDC6 promoters were shown to be most active while the activities of others were close to that of BIRC5 gene (survivin) gene promoter. Long and short variants of each cloned promoter demonstrated very similar cancer specificity with the exception of PLK1-long promoter that was substantially more specific than its short variant and other promoters under study. The data indicate that most of the important cis-regulatory transcription elements responsible for intrinsic cancer specificity are located in short variants of the promoters under study. CDC6 short promoter may serve as a promising candidate for transcription targeted cancer gene therapy.

  16. CRISPR-Cas9: from Genome Editing to Cancer Research. (United States)

    Chen, Si; Sun, Heng; Miao, Kai; Deng, Chu-Xia


    Cancer development is a multistep process triggered by innate and acquired mutations, which cause the functional abnormality and determine the initiation and progression of tumorigenesis. Gene editing is a widely used engineering tool for generating mutations that enhance tumorigenesis. The recent developed clustered regularly interspaced short palindromic repeats-CRISPR-associated 9 (CRISPR-Cas9) system renews the genome editing approach into a more convenient and efficient way. By rapidly introducing genetic modifications in cell lines, organs and animals, CRISPR-Cas9 system extends the gene editing into whole genome screening, both in loss-of-function and gain-of-function manners. Meanwhile, the system accelerates the establishment of animal cancer models, promoting in vivo studies for cancer research. Furthermore, CRISPR-Cas9 system is modified into diverse innovative tools for observing the dynamic bioprocesses in cancer studies, such as image tracing for targeted DNA, regulation of transcription activation or repression. Here, we view recent technical advances in the application of CRISPR-Cas9 system in cancer genetics, large-scale cancer driver gene hunting, animal cancer modeling and functional studies.

  17. Control of cervical cancer: women's options and rights. (United States)

    Cain, Joanna M; Ngan, Hextan; Garland, Suzanne; Wright, Thomas


    Cervical cancer takes the lives of more than 250,000 women each year globally, particularly in under-resourced areas of low-, middle-, and high-income countries. Options for cancer control and treatment have reached a point that there are interventions for control that could be adopted for virtually every resource and demographic situation. Women die despite the availability of attractive control options, which means that educating policy makers, women's health professionals, as well as women themselves, must become a major focus for ongoing control of this disease. The human right to life, to prevention of suffering, and to education are all key rights linked to improving the control of cervical cancer and saving the lives of women, particularly in resource-poor parts of the world.

    Directory of Open Access Journals (Sweden)

    Hui LI


    Full Text Available Lung cancer is the malignant disease with the highest rate in terms of incidence and mortality in China. Early diagnosis and timely monitoring tumor recurrence and metastasis are extremely important for improving 5-year survival rate of lung cancer patients. Circulating tumor cells (CTCs, as a "liquid biopsy specimens” for the primary tumor, provide the possibility to perform real-time, non-invasive histological identification for lung cancer patients. The detection of CTCs contributes to early diagnosis, surveillance of tumor recurrence and metastasis, and prediction of therapeutic efficacy and prognosis. Furthermore, CTCs-dependent detection emerges as a new approach for molecularly pathologic examination, study of molecular mechanisms involved in drug resistance, and resolution for tumor heterogeneity. This study reviewed the recent progress of CTCs in lung cancer research field.

  19. Research advances in traditional Chinese medicine syndromes in cancer patients. (United States)

    Ji, Qing; Luo, Yun-quan; Wang, Wen-hai; Liu, Xuan; Li, Qi; Su, Shi-bing


    Traditional Chinese medicine (TCM) syndrome, also known as TCM ZHENG or TCM pattern, is an integral and essential part of TCM theory that helps to guide the design of individualized treatments. A TCM syndrome, in essence, is a characteristic profile of all clinical manifestations in one patient that can be readily identified by a TCM practitioner. In this article, the authors reviewed the presentations of TCM syndromes in seven common malignancies (liver, lung, gastric, breast, colorectal, pancreatic and esophageal cancers), the objectivity and the standardization of TCM syndrome differentiation, the evaluation of TCM syndrome modeling in cancer research, and syndrome differentiation-guided TCM treatment of cancers. A better understanding of TCM syndrome theory, as well as its potential biological basis, may contribute greatly to the clinical TCM diagnosis and the treatment of cancer.

  20. Differences in Cancer Information Seeking Behavior, Preferences, and Awareness Between Cancer Survivors and Healthy Controls: A National, Population-Based Survey (United States)

    Roach, Abbey R.; Lykins, Emily L.B.; Gochett, Celestine G.; Brechting, Emily H.; Graue, Lili O.; Andrykowski, Michael A.


    Background No research has examined how cancer diagnosis and treatment might alter information source preferences or opinions. Methods Data from 719 cancer survivors (CS group) and 2012 matched healthy controls (NCC group) regarding cancer-related information seeking behavior, preferences, and awareness from the population-based 2003 Health Information National Trends Survey (HINTS) was examined. Results The CS group reported greater consumption of cancer-related information but the CS and NCC groups did not differ in information source use or preferences. The CS group was more confident of their ability to get cancer information, reported more trust in health care professionals and television as cancer information sources, but evaluated their recent cancer information seeking experiences more negatively than the NCC group. Awareness of cancer information resources was surprisingly low in both the CS and NCC groups. Conclusions Cancer diagnosis and treatment subtly alters cancer information seeking preferences and experience. However awareness and use of cancer information resources was relatively low regardless of personal history of cancer. PMID:19259869

    PURPOSE OF REVIEW: This article provides an overview of anticancer therapies in various stages of clinical development as potential interventions to target HIV persistence. RECENT FINDINGS: Epigenetic drugs developed for cancer have been investigated in vitro, ex vivo and in clinical trials...... as interventions aimed at reversing HIV latency and depleting the amount of virus that persists on antiretroviral therapy. Treatment with histone deacetylase inhibitors induced HIV expression in patients on antiretroviral therapy but did not reduce the frequency of infected cells. Other interventions that may...... accelerate the decay of latently infected cells, in the presence or absence of latency-reversing therapy, are now being explored. These include apoptosis-promoting agents, nonhistone deacetylase inhibitor compounds to reverse HIV latency and immunotherapy interventions to enhance antiviral immunity...

  3. Bioinformatics: Tools to accelerate population science and disease control research. (United States)

    Forman, Michele R; Greene, Sarah M; Avis, Nancy E; Taplin, Stephen H; Courtney, Paul; Schad, Peter A; Hesse, Bradford W; Winn, Deborah M


    Population science and disease control researchers can benefit from a more proactive approach to applying bioinformatics tools for clinical and public health research. Bioinformatics utilizes principles of information sciences and technologies to transform vast, diverse, and complex life sciences data into a more coherent format for wider application. Bioinformatics provides the means to collect and process data, enhance data standardization and harmonization for scientific discovery, and merge disparate data sources. Achieving interoperability (i.e. the development of an informatics system that provides access to and use of data from different systems) will facilitate scientific explorations and careers and opportunities for interventions in population health. The National Cancer Institute's (NCI's) interoperable Cancer Biomedical Informatics Grid (caBIG) is one of a number of illustrative tools in this report that are being mined by population scientists. Tools are not all that is needed for progress. Challenges persist, including a lack of common data standards, proprietary barriers to data access, and difficulties pooling data from studies. Population scientists and informaticists are developing promising and innovative solutions to these barriers. The purpose of this paper is to describe how the application of bioinformatics systems can accelerate population health research across the continuum from prevention to detection, diagnosis, treatment, and outcome.

    Directory of Open Access Journals (Sweden)

    Vijayakrishna K Gadi

    Full Text Available BACKGROUND: Prior pregnancy is known to protect against development of breast cancer. Recent studies have demonstrated that pregnancy has the capacity to establish small numbers of immunologically active fetal-derived cells in the mother, a phenomenon known as fetal microchimerism (FMc. We asked whether presence of FMc, routinely acquired during pregnancy, is a protective factor for breast cancer. METHODOLOGY/PRINCIPAL FINDINGS: DNA extracts from peripheral blood specimens were obtained from a population-based case-control study of risk factors for breast cancer in women 21 to 45 years old. Specimens were tested with quantitative PCR for presence and concentrations of male DNA presumed to derive from prior pregnancies with a male fetus. Odds ratios (OR and 95% confidence intervals (CI were estimated with consideration of multiple established reproductive and environmental risk factors for breast cancer. FMc results were generated on 99 parous women, 54 with primary invasive breast cancer and 45 general population controls. FMc prevalence was 56% (25/45 and 26% (14/54 in controls and cases, respectively. Women harboring FMc were less likely to have had breast cancer (OR = 0.29, 95% CI 0.11-0.83; p = 0.02, adjusting for age, number of children, birth of a son, history of miscarriage, and total DNA tested. In addition, FMc concentrations were higher in controls versus cases (p = 0.01. Median concentrations were 2 (0-78 and 0 (0-374 fetal genomes/10(6 maternal genomes in controls and cases, respectively. CONCLUSIONS: Results suggest that the enigma of why some parous women are not afforded protection from breast cancer by pregnancy might in part be explained by differences in FMc. Mechanistic studies of FMc-derived protection against breast cancer are warranted.

    Alliance Against Cancer (ACC) was established in Rome in 2002 as a consortium of six Italian comprehensive cancer centers (Founders). The aims of ACC were to promote a network among Italian oncologic institutions in order to develop specific, advanced projects in clinical and translational research. During the following years, many additional full and associate members joined ACC, that presently includes the National Institute of Health, 17 research-oriented hospitals, scientific and patient organizations. Furthermore, in the last three years ACC underwent a reorganization process that redesigned the structure, governance and major activities. The present goal of ACC is to achieve high standards of care across Italy, to implement and harmonize principles of modern personalized and precision medicine, by developing cost effective processes and to provide tailored information to cancer patients. We herein summarize some of the major initiatives that ACC is currently developing to reach its goal, including tumor genetic screening programs, establishment of clinical trial programs for cancer patients treated in Italian cancer centers, facilitate their access to innovative drugs under development, improve quality through an European accreditation process (European Organization of Cancer Institutes), and develop international partnerships. In conclusion, ACC is a growing organization, trying to respond to the need of networking in Italy and may contribute significantly to improve the way we face cancer in Europe.

  6. Multi-targeted approach to cancer treatment: an international translational cancer research symposium. (United States)

    Mehta, Kapil; Gandhi, Varsha; Pathak, Sen; Aggarwal, Bharat B; Grover, Rajesh K


    Whether it is chronic myeloid leukemia, ALK-expressing malignancies, or HER2-positive breast cancer, targeted-therapies for treatment of human cancers have shown great promise. However, as they hit a single molecule expressed in neoplastic cells, their use is frequently associated with development of resistance. In cancer cells many signaling pathways operate in parallel, hence the idea of multi-targeted therapy is prevailing. The Society of Translational Cancer Research held its biennial meeting in the capital city of India, Delhi from February 6th through 9th, 2014 to discuss 'Multi-targeted Approach to Treatment of Cancer'. Over 200 scientists, clinicians, trainees, and industry representatives from different countries gathered in Vigyan Bhavan, the hotspot of Delhi for four days to talk and discuss on a variety of topics related to multi-targeted therapeutic approaches. Talks were presented by leaders in the cancer research field from various countries. It became clear from this conference that coupling multiple targeted-agents or using an agent that hits an individual target in several independent locations in the disease-causing pathway(s) may be the best approach to treat different cancers.

  7. Translational genomics in cancer research:converting proifles into personalized cancer medicine

    Institute of Scientific and Technical Information of China (English)

    Lalit Patel; Brittany Parker; Da Yang; Wei Zhang


    Cancer genomics is a rapidly growing discipline in which the genetic molecular basis of malignancy is studied at the scale of whole genomes. While the discipline has been successful with respect to identifying specific oncogenes and tumor suppressors involved in oncogenesis, it is also challenging our approach to managing patients suffering from this deadly disease. Speciifcally cancer genomics is driving clinical oncology to take a more molecular approach to diagnosis, prognostication, and treatment selection. We review here recent work undertaken in cancer genomics with an emphasis on translation of genomic ifndings. Finally, we discuss scientiifc challenges and research opportunities emerging from ifndings derived through analysis of tumors with high-depth sequencing.

  8. Mapping cancer, cardiovascular and malaria research in Brazil

    Directory of Open Access Journals (Sweden)

    P.S. Rodrigues


    Full Text Available This paper presents performance indicators for the Brazilian cancer, cardiovascular and malaria research areas from 1981 to 1995. The data show an increasing number of papers since 1981 and author numbers indicate a continuous growth of the scientific community and suggest an expected impact of scientific activity on biomedical education. The data also characterize cardiovascular research as a well-established area and cancer research as a faster growing consolidating field. The 1989-1994 share of Brazilian articles among world publications shows a growing trend for the cancer (1.61 and cardiovascular (1.59 areas, and a decrease for the malaria area (0.89. The burden of the three diseases on society is contrasted by the small number of consolidated Brazilian research groups, and a questionable balance of thematic activity, especially with regard to malaria. Brazilian periodicals play an important role in increasing the international visibility of science produced in the country. Cancer and cardiovascular research is strongly concentrated in the Southeastern and in Southern regions of Brazil, especially in São Paulo (at least one address from São Paulo in 64.5% of the 962 cancer articles and in 66.9% of the 2250 cardiovascular articles, the second state being Rio de Janeiro with at least one address in 14.1 and 11% of those articles, respectively. Malaria research (468 articles is more evenly distributed across the country, following the pattern of the endemic distribution of the disease. Surveying these national indicator trends can be useful to establish policies in the decision process about health sciences, medical education and public health.

  9. Prevention and Treatment of Cancer: Hypes and Hopes 6th International Translational Cancer Research Conference. (United States)

    Patel, Prabhudas; Vora, Hemangini; Aggarwal, Bharat B; Gandhi, Varsha; Mehta, Kapil; Pathak, Sen


    Cancer is primarily an "old-age" disease that has an "age-old" history. The overall incidence of cancer is much higher in Western countries, but is rapidly growing in Eastern countries perhaps due to change in life-style. Almost three million studies published to date indicate that cancer is a hyperproliferative disorder that arises from dysregulation of multiple cell signaling pathways. The cancer genome landscape indicates that approximately 140 genes and 12 cell signaling pathways drive almost all cancers. "Targeted therapy," a buzz word in cancer treatment for the past two decades, has provided antibodies, as well as small-molecule inhibitors. These therapies have been successful only in few instances. However, in most cases, minor increase in overall survival has been reported at the cost of huge expense. An alternative strategy is to prevent cancer or to diagnose and treat the disease at an early stage to gain survival benefits. Such interventions are also cost-effective. To address some of these issues, the 6th International Translational Cancer Research Conference was held during February 4-7th, 2016, in Ahmedabad, Gujarat, India; the homeland of Mahatma Gandhi. This conference was focused on utilizing multidisciplinary approaches for prevention and early treatment that would likely simultaneously or sequentially target many key pathways. Several distinguished speakers were invited from around the world. This article highlights primary features of this conference.

    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.

  13. A pilot randomized controlled trial testing a minimal intervention to prepare breast cancer survivors for recovery (United States)

    Sterba, Katherine Regan; Armeson, Kent; Franco, Regina; Harper, Jennifer; Patten, Rebecca; Kindall, Stacey; Bearden, James; Zapka, Jane


    Background Interventions addressing cancer survivors’ post-treatment concerns can be time-intensive and require specialized staff. Research is needed to identify feasible minimal intervention strategies to improve survivors’ quality of life after treatment. Objectives The objectives of this study were to evaluate the feasibility and short-term impact of a minimal clinic intervention on breast cancer survivors’ quality of life, unmet needs, distress and cancer worry. Interventions/Methods In this randomized controlled pilot trial, we enrolled breast cancer survivors at the end of treatment and administered baseline surveys. Participants were randomized to study arm (4-week video plus educational booklet intervention group and usual care group) and completed follow-up surveys at 10 weeks. Linear regression was used to examine intervention effects on quality of life outcomes controlling for clinical and demographic factors. Open-ended questions were used to examine program satisfaction and obtain feedback to improve the intervention. Results We enrolled 92 survivors in the trial. Participants rated the intervention highly and reported feeling less isolated and having more realistic expectations about their recovery after completing the program. Despite positive qualitative findings, no significant intervention effects were observed for quality of life, unmet needs, distress or cancer worry in unadjusted or adjusted analyses. Conclusions Future research is needed to define optimal intervention elements to prepare breast cancer survivors for the post-treatment period. Implications for Practice Effective survivorship interventions may require more intensive components such as clinical input and longer follow-up periods. PMID:24831043

  16. The future of cancer research: prevention, screening, vaccines, and tumor-specific drug combos. (United States)

    Blanck, George


    New cancer research strategies have developed very rapidly over the past five years, including extensive DNA sequencing of tumor and normal cells; use of highly sensitive cancer cell detection methods; vaccine development and tumor-specific (designer) drugs. These developments have raised questions about where to concentrate efforts in the near future when establishing clinical trials, particularly important in an age of diminishing resources and during a period when competing strategies for cancer control are likely to overwhelm the opportunities for establishing large, effective clinical trials. In particular, it behooves the research community to be mindful of the inevitable, challenging obligation to responsibly choose between clinical trials that offer the credible hope of incremental advances vs. trials that are less traditional but may have revolutionary outcomes.

  17. Occupations and lung cancer: a population-based case-control study in British Columbia. (United States)

    Yenugadhati, Nagarajkumar; Birkett, Nicholas J; Momoli, Franco; Krewski, Daniel


    An investigation based on a large population-based case-control study in British Columbia, Canada, was conducted to identify high-risk occupations for lung cancer by histological subtypes. Subjects were 14,755 male incident cancer cases for whom lifetime occupational histories and information on smoking and relevant covariates were collected. Occupational associations for 2998 lung cancer cases, including histological subtypes, were assessed by logistic regression using other cancer cases, excluding smoking-related cancers, as controls. An excess risk of lung cancer was found among workers in metal processing, bakers, and ship deck crew for all histological subtypes, and construction workers, chefs and cooks, and medical workers for specific histological subtypes. Occupational associations that are unique to histological subtypes of lung cancer were identified. Owing to a scarcity of literature in this area, future research needs to focus on confirming these histological associations, and identifying the risk from key exposures found within these occupations (e.g., medical radiation, electromagnetic fields, and cooking fumes).

    Full Text Available Jingwu Xie, Christopher M Bartels, Scott W Barton, Dongsheng GuWells Center for Pediatric Research, Division of Hematology and Oncology, Department of Pediatrics, Indiana University Simon Cancer Center, Indiana University, Indianapolis, IN, USAAbstract: Since its first description in Drosophila by Drs Nusslein-Volhard and Wieschaus in 1980, hedgehog (Hh signaling has been implicated in regulation of cell differentiation, proliferation, tissue polarity, stem cell maintenance, and carcinogenesis. The first link of Hh signaling to cancer was established through studies of Gorlin syndrome in 1996 by two independent teams. Later, it was shown that Hh signaling may be involved in many types of cancer, including skin, leukemia, lung, brain, and gastrointestinal cancers. In early 2012, the US Food and Drug Administration approved the clinical use of Hh inhibitor Erivedge/vismodegib for treatment of locally advanced and metastatic basal cell carcinomas. With further investigation, it is possible to see more clinical applications of Hh signaling inhibitors. In this review, we will summarize major advances in the last 3 years in our understanding of Hh signaling activation in human cancer, and recent developments in preclinical and clinical studies using Hh signaling inhibitors.Keywords: hedgehog, smoothened, PTCH1, cancer, signal transduction, clinical trials, animal model

  20. Bioengineered models of solid human tumors for cancer research (United States)

    Marturano-Kruik, Alessandro; Villasante, Aranzazu; Vunjak-Novakovic, Gordana


    Summary The lack of controllable in vitro models that can recapitulate the features of solid tumors such as Ewing’s sarcoma limits our understanding of the tumor initiation and progression and impedes the development of new therapies. Cancer research still relies of the use of simple cell culture, tumor spheroids, and small animals. Tissue-engineered tumor models are now being grown in vitro to mimic the actual tumors in patients. Recently, we have established a new protocol for bioengineering the Ewing’s sarcoma, by infusing tumor cell aggregates into the human bone engineered from the patient’s mesenchymal stem cells. The bone niche allows crosstalk between the tumor cells, osteoblasts and supporting cells of the bone, extracellular matrix and the tissue microenvironment. The bioreactor platform used in these experiments also allows the implementation of physiologically relevant mechanical signals. Here, we describe a method to build an in vitro model of Ewing’s sarcoma that mimics the key properties of the native tumor and provides the tissue context and physical regulatory signals.

  2. Leveraging the power of pooled data for cancer outcomes research

    Institute of Scientific and Technical Information of China (English)

    Kiara Hugh-Yeun; Winson Y. Cheung


    Background: Clinical trials continue to be the gold standard for determining the effcacy of novel cancer treatments, but they may also expose participants to the potential risks of unpredictable or severe toxicities. The development of validated tools that better inform patients of the beneifts and risks associated with clinical trial participation can facilitate the informed consent process. The design and validation of such instruments are strengthened when we leverage the power of pooled data analysis for cancer outcomes research. Main body: In a recent study published in the Journal of Clinical Oncology entitled“Determinants of early mortal‑ity among 37,568 patients with colon cancer who participated in 25 clinical trials from the adjuvant colon cancer endpoints database,”using a large pooled analysis of over 30,000 study participants who were enrolled in clinical trials of adjuvant therapy for early‑stage colon cancer, we developed and validated a nomogram depicting the predictors of early cancer mortality. This database of pooled individual‑level data allowed for a comprehensive analysis of poor prognostic factors associated with early death;furthermore, it enabled the creation of a nomogram that was able to reliably capture and quantify the beneift‑to‑risk proifle for patients who are considering clinical trial participation. This tool can facilitate treatment decision‑making discussions. Conclusion: As China and other Asian countries continue to conduct oncology clinical trials, efforts to collate patient‑level information from these studies into a large data repository should be strongly considered since pooled data can increase future capacity for cancer outcomes research, which, in turn, can enhance patient‑physician discus‑sions and optimize clinical care.

  3. Cancer research and therapy: Where are we today?

    Directory of Open Access Journals (Sweden)

    Sampada Sawant


    Full Text Available Till date scientists are struggling to understand the complete mechanism of carcinogenesis. In future, the real time detection of cancer may help scientists to identify some of the complicated biological mechanisms. Certain special features of cancer cells enable researchers to deliver the drug or to develop the right drug therapy. These cell properties include over expression or over activity in uptake of certain nutrients e.g. folic acid and increased permeability. Listed properties might vary depending upon the type of cancer and can be fully exploited by using nanoparticles either to detect the site of cancer or to direct the drug at the affected site. Product approach like drug conjugates, complexes serves as a good platform to solve issues like solubility, toxicity, poor penetration and stability related to cancer drugs. Beside this, several drug delivery platforms are under development by researchers in academia as well as in industry to deliver therapeutic molecules and new chemical entities to the targeted site in body. Amongst them, nanotechnology both at molecular and supramolecular level is a leading platform and can help to image, detect and treat cancer. Surface modification of nanoparticles by coating or anchoring their surface with special markers, materials, peptide, proteins, antibodies or antigens add extra feature and thereby can enhance the effectiveness. These treatments can be used individually or in combined form. In this review, advances on nanotechnological platform are discussed together with some assisting techniques like magnetic field, photo or light field, sonic rays are touched upon. New biological therapies that are advancing in this direction include the antisense therapy, cell therapy, gene therapy, radiation therapy and SiRNA interfaces which are discussed in brief in this article.

    Full Text Available Background: Researchers have reported association of plasma/serum lipids and lipoproteins with different cancers. Increase levels of circulating lipids and lipoproteins have been associated with breast cancer risk. Aim: The aim of this study is to compare serum lipid profiles: total-cholesterol (T-CHOL, triglyceride (TG, high density lipoprotein-cholesterol (HDL-C, low density lipoprotein-cholesterol (LDL-C and very low density lipoprotein-cholesterol (VLDL-C between breast cancer patients and normal participants. Materials and Methods: A total of 403 women in this study were divided into two groups in the period during May 2006-April 2007. Blood samples were collected from 249 patients with early stage breast cancer and 154 normal controls for serum lipid profiles (T-CHOL, TG, HDL-C, LDL-C and VLDL-C analysis using Hitachi 717 Autoanalyzer (Roche Diagnostic GmbH, Germany. TG, LDL-C and VLDL-C levels in breast cancer group were significantly increased as compared with normal controls group (P < 0.001, whereas HDL-C and T-CHOL levels were not. Results: The results of this study suggest that increased serum lipid profiles may associate with breast cancer risk in Thai women. Further studies to group important factors including, cancer stages, types of cancer, parity, and menopausal status that may affect to lipid profiles in breast cancer patients along with an investigation of new lipid profiles to clarify most lipid factors that may involve in breast cancer development are needed.

  8. Community-based participatory research: its role in future cancer research and public health practice. (United States)

    Simonds, Vanessa W; Wallerstein, Nina; Duran, Bonnie; Villegas, Malia


    The call for community-based participatory research approaches to address cancer health disparities is increasing as concern grows for the limited effectiveness of existing public health practice and research in communities that experience a disparate burden of disease. A national study of participatory research projects, Research for Improved Health, funded by the National Institutes of Health (2009-2013), identified 64 of 333 projects focused on cancer and demonstrated the potential impact participatory approaches can have in reducing cancer disparities. Several projects highlight the success of participatory approaches to cancer prevention and intervention in addressing many of the challenges of traditional practice and research. Best practices include adapting interventions within local contexts, alleviating mistrust, supporting integration of local cultural knowledge, and training investigators from communities that experience cancer disparities. The national study has implications for expanding our understanding of the impact of participatory approaches on alleviating health disparities and aims to enhance our understanding of the barriers and facilitators to effective community-based participatory research.

  9. Collaboration - Office of Cancer Clinical Proteomics Research (United States)

    Despite great strides in proteomics and the growing number of articles citing the discovery of potential biomarkers, the actual rate of introduction of Food and Drug Administration (FDA) approved protein analytes has been relatively unchanged over the past 10 years. One of reasons for the lack of new protein-based biomarkers approved has been a lack of information and understanding by the proteomics research community to the regulatory process used by the FDA.

To assess capacity to modulate endogenous DNA damage among radiologic technologists who had been diagnosed with breast cancer and another malignancy (breast-other; n=42), early-onset breast cancer (early-onset, age {<=} 35; n=38), thyroid cancer (n=68), long-lived cancer-free individuals (hyper-normals; n=20) and cancer-free controls (n=49) we quantified DNA damage (single strand breaks and abasic sites) in untreated lymphoblastoid cell lines using the alkaline comet assay. Komet{trademark} software provided comet tail length, % DNA in tail (tail DNA), comet distributed moment (CDM), and Olive tail moment (OTM) summarized as the geometric mean of 100 cells. Category cut-points (median and 75th percentile) were determined from the distribution among controls. Tail length (for {>=} 75% vs. below the median, age adjusted) was most consistently associated with the highest odds ratios in the breast-other, early-onset, and thyroid cancer groups (with risk increased 10-, 5- or 19-fold, respectively, with wide confidence intervals) and decreased risk among the hyper-normal group. For the other three Comet measures, risk of breast-other was elevated approximately three-fold. Risk of early-onset breast cancer was mixed and risk of thyroid cancer ranged from null to a two-fold increase. The hyper-normal group showed decreased odds ratios for tail DNA and OTM, but not CDM. DNA damage, as estimated by all Comet measures, was relatively unaffected by survival time, reproductive factors, and prior radiation treatment. We detected a continuum of endogenous DNA damage that was highest among cancer cases, less in controls, and suggestively lowest in hyper-normal individuals. Measuring this DNA damage phenotype may contribute to the identification of susceptible sub-groups. Our observations require replication in a prospective study with a large number of pre-diagnostic samples.

  12. The value of research collaborations and consortia in rare cancers. (United States)

    Blay, Jean-Yves; Coindre, Jean-Michel; Ducimetière, Françoise; Ray-Coquard, Isabelle


    Rare cancers are defined by an incidence of less than six per 100,000 people per year. They represent roughly 20% of all human cancers and are associated with worse survival than are so-called frequent tumours, because of delays to accurate diagnosis, inadequate treatments, and fewer opportunities to participate in clinical trials (because of a paucity of dedicated trials from both academic and industrial sponsors). In this Series paper, we discuss how these challenges can be addressed by research consortia and suggest the integration of these consortia with reference networks, which gather multidisciplinary expert centres, for management of rare tumours.

  13. Clinical cancer research: the past, present and the future. (United States)

    DeVita, Vincent T; Eggermont, Alexander M M; Hellman, Samuel; Kerr, David J


    In the past decade, we have witnessed unprecedented changes and some remarkable advances that have enabled true personalized medicine. Nevertheless, many challenges in clinical cancer research remain and need to be overcome if we are to witness similar progress in the next decade. Such hurdles include, but are not limited to, clinical development and testing of multiple agents in combination, design of clinical trials to best accommodate the ever increasing knowledge of heterogeneity of the disease, regulatory challenges relating to drug development and trial design, and funding for basic research. With this in mind, we asked four leading cancer researchers from around the world, and who have been associated with the journal since its launch in November 2004 what, in their opinion, we have learnt over the past 10 years and how we should progress in the next 10 years.

  14. Why is it crucial to reintegrate pathology into cancer research? (United States)

    Rodriguez-Canales, Jaime; Eberle, Franziska C; Jaffe, Elaine S; Emmert-Buck, Michael R


    The integration of pathology with molecular biology is vital if we are to enhance the translational value of cancer research. Pathology represents a bridge between medicine and basic biology, it remains the gold standard for cancer diagnosis, and it plays an important role in discovery studies. In the past, pathology and cancer research were closely associated; however, the molecular biology revolution has shifted the focus of investigators toward the molecular alterations of tumors. The reductionist approach taken in molecular studies is producing great insight into the inner workings of neoplasia, but it can also minimize the importance of histopathology and of understanding the disease as a whole. In turn, pathologists can underestimate the role of molecular studies in developing new ancillary techniques for clinical diagnosis. A multidisciplinary approach that integrates pathology and molecular biology within a translational research system is needed. This process will require overcoming cultural barriers and can be achieved through education, a more effective incorporation of pathology into biological research, and conversely an integration of biological research into the pathology laboratory.

  18. A bibliometric analysis of diets and breast cancer research. (United States)

    Kotepui, Manas; Wannaiampikul, Sivaporn; Chupeerach, Chaowanee; Duangmano, Suwit


    Breast cancer is the most common cancer among women worldwide. The primary aim of this work was to provide an in-depth evaluation of research publications in the field of diets and breast cancer. The impact of economic outcome on national academic productivity was also investigated. Data were retrieved using Pubmed for English-language publications. The search included all research for which articles included words relating to "diets and breast cancer". Population and national income data were obtained from publicly available databases. Impact factors for journals were obtained from Journal Citation Reports® (Thomson Scientific). There were 2,396 publications from 60 countries in 384 journals with an impact factor. Among them, 1,652 (68.94%) publications were Original articles. The United States had the highest quantity (51% of total) and highest of mean impact factor (8.852) for publication. Sweden had the highest productivity of publication when adjusted for number of population (6 publications per million population). Publications from the Asian nation increased from 5.3% in 2006 to 14.6% in 2012. The Original article type was also associated with geography (p<0.001; OR=2.183; 95%CI=1.526-3.123), Asian countries produced more proportion of Original articles (82%) than those of rest of the world (67.6%). Diets and breast cancer-associated research output continues to increase annually worldwide including publications from Asian countries. Although the United States produced the most publications, European nations per capita were higher in publication output.

  19. Tissue-engineered models of human tumors for cancer research (United States)

    Villasante, Aranzazu; Vunjak-Novakovic, Gordana


    Introduction Drug toxicity often goes undetected until clinical trials, which are the most costly and dangerous phase of drug development. Both the cultures of human cells and animal studies have limitations that cannot be overcome by incremental improvements in drug-testing protocols. A new generation of bioengineered tumors is now emerging in response to these limitations, with potential to transform drug screening by providing predictive models of tumors within their tissue context, for studies of drug safety and efficacy. An area that could greatly benefit from these models is cancer research. Areas covered In this review, the authors first describe the engineered tumor systems, using Ewing's sarcoma as an example of human tumor that cannot be predictably studied in cell culture and animal models. Then, they discuss the importance of the tissue context for cancer progression and outline the biomimetic principles for engineering human tumors. Finally, they discuss the utility of bioengineered tumor models for cancer research and address the challenges in modeling human tumors for use in drug discovery and testing. Expert opinion While tissue models are just emerging as a new tool for cancer drug discovery, they are already demonstrating potential for recapitulating, in vitro, the native behavior of human tumors. Still, numerous challenges need to be addressed before we can have platforms with a predictive power appropriate for the pharmaceutical industry. Some of the key needs include the incorporation of the vascular compartment, immune system components, and mechanical signals that regulate tumor development and function. PMID:25662589

  20. EXOS research on force-reflecting controllers (United States)

    Eberman, Brian S.; An, Bin


    EXOS has developed two state of the art prototype master controllers for controlling robot hands and manipulators under the Small Business Innovation Research (SBIR) program with NASA. One such device is a two degree-of-freedom Sensing and Force Reflecting Exoskeleton (SAFiRE) worn on the operator's hand. The device measures the movement of the index finger and reflects the interaction forces between the slave robot and the environment to the human finger. The second device is a position sensing Exoskeleton ArmMaster (EAM) worn by a human operator. The device simultaneously tracks the motions of the operator's three DOF shoulder and two DOF elbow. Both of these devices are currently used to control robots at NASA. We are currently developing a full fingered SAFiRE and a position sensing and force reflecting EAM under two second phase SBIR grants with NASA. This paper will include discussions of: (1) the design of the current prototypes, (2) kinematics of the EAM and force control of the SAFiRE, (3) design issues that must be addressed in developing more advanced versions, and (4) our progress to date in addressing these issues.

  2. Cancer genomics object model: an object model for multiple functional genomics data for cancer research. (United States)

    Park, Yu Rang; Lee, Hye Won; Cho, Sung Bum; Kim, Ju Han


    The development of functional genomics including transcriptomics, proteomics and metabolomics allow us to monitor a large number of key cellular pathways simultaneously. Several technology-specific data models have been introduced for the representation of functional genomics experimental data, including the MicroArray Gene Expression-Object Model (MAGE-OM), the Proteomics Experiment Data Repository (PEDRo), and the Tissue MicroArray-Object Model (TMA-OM). Despite the increasing number of cancer studies using multiple functional genomics technologies, there is still no integrated data model for multiple functional genomics experimental and clinical data. We propose an object-oriented data model for cancer genomics research, Cancer Genomics Object Model (CaGe-OM). We reference four data models: Functional Genomic-Object Model, MAGE-OM, TMAOM and PEDRo. The clinical and histopathological information models are created by analyzing cancer management workflow and referencing the College of American Pathology Cancer Protocols and National Cancer Institute Common Data Elements. The CaGe-OM provides a comprehensive data model for integrated storage and analysis of clinical and multiple functional genomics data.

  5. Overcoming the challenges to consumer involvement in cancer research


    Stevens, Tony; Wilde, David; Hunt, John; Ahmedzai, Sam H


    Introduction  Within the last decade, there have been many government initiatives to promote consumer involvement in research, especially in cancer. At the same time, the number and influence of consumer groups themselves have expanded. However, the organizational infrastructure necessary to facilitate consumer involvement has not been developed. Consequently, consumer involvement has tended to remain essentially localized and project driven, with no strategic or regional lead.

  6. Increasing participation of cancer patients in randomised controlled trials: a systematic review

    Directory of Open Access Journals (Sweden)

    Stirk Lisa


    Full Text Available Abstract Background There are many barriers to patient participation in randomised controlled trials of cancer treatments. To increase participation in trials, strategies need to be identified to overcome these barriers. Our aim was to assess the effectiveness of interventions to overcome barriers to patient participation in randomised controlled trials (RCTs of cancer treatments. Methods A systematic review was conducted. Published and unpublished studies in any language were searched for in fifteen electronic databases, including MEDLINE, EMBASE, CINAHL and PsycINFO, from inception to the end of 2004. Studies of any interventions to improve cancer patient participation in RCTs, which reported the change in recruitment rates, were eligible for inclusion. RCTs and non-randomised controlled trials as well as before and after studies reporting baseline rates specific to the population being investigated were included. Data were extracted by one reviewer into structured summary tables and checked for accuracy by a second reviewer. Each included study was assessed against a checklist for methodological quality by one reviewer and checked by a second reviewer. A narrative synthesis was conducted. Results Eight studies were identified that met the inclusion criteria: three RCTs, two non-randomised controlled trials and three observational studies. Six of the studies had an intervention that had some relevance to the UK. There was no robust evidence that any of the interventions investigated led to an increase in cancer patient participation in RCTs, though one good quality RCT found that urologists and nurses were equally effective at recruiting participants to a treatment trial for prostate cancer. Although there was no evidence of an effect in any of the studies, the evidence was not of sufficient quality to be able to conclude that these interventions therefore do not work. Conclusion There is not a strong evidence-base for interventions that

  8. Optimal control for mathematical models of cancer therapies an application of geometric methods

    CERN Document Server

    Schättler, Heinz


    This book presents applications of geometric optimal control to real life biomedical problems with an emphasis on cancer treatments. A number of mathematical models for both classical and novel cancer treatments are presented as optimal control problems with the goal of constructing optimal protocols. The power of geometric methods is illustrated with fully worked out complete global solutions to these mathematically challenging problems. Elaborate constructions of optimal controls and corresponding system responses provide great examples of applications of the tools of geometric optimal control and the outcomes aid the design of simpler, practically realizable suboptimal protocols. The book blends mathematical rigor with practically important topics in an easily readable tutorial style. Graduate students and researchers in science and engineering, particularly biomathematics and more mathematical aspects of biomedical engineering, would find this book particularly useful.

  9. Consumer input into research: the Australian Cancer Trials website

    Directory of Open Access Journals (Sweden)

    Butow Phyllis N


    Full Text Available Abstract Background The Australian Cancer Trials website (ACTO was publicly launched in 2010 to help people search for cancer clinical trials recruiting in Australia, provide information about clinical trials and assist with doctor-patient communication about trials. We describe consumer involvement in the design and development of ACTO and report our preliminary patient evaluation of the website. Methods Consumers, led by Cancer Voices NSW, provided the impetus to develop the website. Consumer representative groups were consulted by the research team during the design and development of ACTO which combines a search engine, trial details, general information about trial participation and question prompt lists. Website use was analysed. A patient evaluation questionnaire was completed at one hospital, one week after exposure to the website. Results ACTO's main features and content reflect consumer input. In February 2011, it covered 1, 042 cancer trials. Since ACTO's public launch in November 2010, until the end of February 2011, the website has had 2, 549 new visits and generated 17, 833 page views. In a sub-study of 47 patient users, 89% found the website helpful for learning about clinical trials and all respondents thought patients should have access to ACTO. Conclusions The development of ACTO is an example of consumers working with doctors, researchers and policy makers to improve the information available to people whose lives are affected by cancer and to help them participate in their treatment decisions, including consideration of clinical trial enrolment. Consumer input has ensured that the website is informative, targets consumer priorities and is user-friendly. ACTO serves as a model for other health conditions.

    Full Text Available Abstract Background Correct control selection is crucial to the internal validity of case-control studies. Little information exists on differences between population and hospital controls in case-control studies on cancers in Chinese hospital setting. Methods We conducted three parallel case-control studies on leukemia, breast and colorectal cancers in China between 2009 and 2010, using population and hospital controls to separately match 540 incident cases by age, gender and residency at a 1:1 ratio. Demographic and lifestyle factors were measured using a validated questionnaire in face-to-face interview. Odds ratios (ORs and 95% confidence intervals (CIs were obtained using conditional logistic regression analyses. Results The two control groups had closely similar exposure distributions of 15 out of 16 factors, with the only exception being that hospital controls were less likely to have a BMI ≥ 25 (OR = 0.71, 95% CI: 0.54, 0.93. For exposure of green tea drinking, the adjusted ORs (95% CIs comparing green tealeaves intake ≥ 1000 grams annually with non-drinkers were 0.51 (0.31, 0.83 and 0.21 (0.27, 0.74 for three cancers combined, 0.06 (0.01, 0.61 and 0.07 (0.01, 0.47 for breast cancer, 0.52 (0.29, 0.94 and 0.45 (0.25, 0.82 for colorectal cancer, 0.65 (0.08, 5.63 and 0.57 (0.07, 4.79 for leukemia using hospital and population controls respectively. Conclusions The study found that hospital controls were comparable with population controls for most demographic characteristics and lifestyle factors measured, but there was a slight difference between the two control groups. Hospital outpatients provide a satisfactory control group in hospital-based case-control study in the Chinese hospital setting.

  12. Birth control pills, cigarettes, alcohol linked to liver cancer. (United States)


    Data on 74 pathologically confirmed cases of liver cancer among blacks and whites living in Los Angeles County, California were compared with 162 matched controls. The study was limited to only people with no hepatitis infection and to non-Asians. The risk of liver cancer for women who have used OCs for 5 years was 5.5 times higher than that for women who had never used OCs. This risk was 3 times higher for women who had ever used OCs. The data for women who were in their reproductive years when OCs 1st entered the market in the 1960s showed that the risk for 5 years of OC use increased to almost 30 times that of women who had never used OCs. Even though estrogens were presumed to be the risk factor since they induce liver cancer in animals, no significant association was found between estrogens used in estrogen replacement therapy and liver cancer. Overall, diabetics were at 3.3 times the risk for liver cancer compared with nondiabetics. People who had diabetes for at least 10 years had 4.3 times the risk and those dependent on insulin injections had 18.5 times the risk. Cigarette smokers had a 2.1 times greater risk of liver cancer than nonsmokers. Most of the women did not drink heavily which showed the independent effect of cigarette smoking. As of December 1991, these data represented the best data on OCs and cigarette smoking to date. The risk for heavy drinkers of alcohol (80g of alcohol/day=9 cans of beer, 9 glasses of wine, or 9 shots of spirits) was 4.7 times the risk of nondrinkers or light drinkers. It is concluded that alcohol and/or cigarettes caused 56% of liver cancer cases in men and that cigarettes and/or OCs caused 54% of liver cancer cases in women.

  14. Spatial analysis of childhood cancer: a case/control study.

    Directory of Open Access Journals (Sweden)

    Rebeca Ramis

    Full Text Available Childhood cancer was the leading cause of death among children aged 1-14 years for 2012 in Spain. Leukemia has the highest incidence, followed by tumors of the central nervous system (CNS and lymphomas (Hodgkin lymphoma, HL, and Non-Hodgkin's lymphoma, NHL. Spatial distribution of childhood cancer cases has been under concern with the aim of identifying potential risk factors.The two objectives are to study overall spatial clustering and cluster detection of cases of the three main childhood cancer causes, looking to increase etiological knowledge.We ran a case-control study. The cases were children aged 0 to 14 diagnosed with leukemia, lymphomas (HL and NHL or CNS neoplasm in five Spanish regions for the period 1996-2011. As a control group, we used a sample from the Birth Registry matching every case by year of birth, autonomous region of residence and sex with six controls. We geocoded and validated the address of the cases and controls. For our two objectives we used two different methodologies. For the first, for overall spatial clustering detection, we used the differences of K functions from the spatial point patterns perspective proposed by Diggle and Chetwynd and the second, for cluster detection, we used the spatial scan statistic proposed by Kulldorff with a level for statistical significance of 0.05.We had 1062 cases of leukemia, 714 cases of CNS, 92 of HL and 246 of NHL. Accordingly we had 6 times the number of controls, 6372 controls for leukemia, 4284 controls for CNS, 552 controls for HL and 1476 controls for NHL. We found variations in the estimated empirical D(s for the different regions and cancers, including some overall spatial clustering for specific regions and distances. We did not find statistically significant clusters.The variations in the estimated empirical D(s for the different regions and cancers could be partially explained by the differences in the spatial distribution of the population; however, according to the

  19. Cancer Research Participation Beliefs and Behaviors of a Southern Black Population: A Quantitative Analysis of the Role of Structural Factors in Cancer Research Participation. (United States)

    Farr, Deeonna E; Brandt, Heather M; Comer, Kimberly D; Jackson, Dawnyéa D; Pandya, Kinjal; Friedman, Daniela B; Ureda, John R; Williams, Deloris G; Scott, Dolores B; Green, Wanda; Hébert, James R


    Increasing the participation of Blacks in cancer research is a vital component of a strategy to reduce racial inequities in cancer burden. Community-based participatory research (CBPR) is especially well-suited to advancing our knowledge of factors that influence research participation to ultimately address cancer-related health inequities. A paucity of literature focuses on the role of structural factors limiting participation in cancer research. As part of a larger CBPR project, we used survey data from a statewide cancer needs assessment of a Black faith community to examine the influence of structural factors on attitudes toward research and the contributions of both structural and attitudinal factors on whether individuals participate in research. Regression analyses and non-parametric statistics were conducted on data from 727 adult survey respondents. Structural factors, such as having health insurance coverage, experiencing discrimination during health care encounters, and locale, predicted belief in the benefits, but not the risks, of research participation. Positive attitudes toward research predicted intention to participate in cancer research. Significant differences in structural and attitudinal factors were found between cancer research participants and non-participants; however, directionality is confounded by the cross-sectional survey design and causality cannot be determined. This study points to complex interplay of structural and attitudinal factors on research participation as well as need for additional quantitative examinations of the various types of factors that influence research participation in Black communities.

    The Arab world, stretching from Lebanon and Syria in the north, through to Morocco in the west, Yemen in the south and Iraq in the east, is the home of more than 300 million people. Cancer is already a major problem and the lifestyle changes underlying the markedly increasing rates for diabetes mean that the burden of neoplasia will only become heavier over time, especially with increasing obesity and aging of what are now still youthful populations. The age-distributions of the affected patients in fact might also indicate cohort effects in many cases. There are a number of active registries in the region and population-based data are now available for a considerable number of countries. A body of Arab scientists is also contributing to epidemiological research into the causes of cancer and how to develop effective control programs. The present review covers the relevant PubMed literature and cancer incidence data from various sources, highlighting similarities and variation in the different cancer types, with attempts to explain disparities with reference to possible environmental factors. In males, the most prevalent cancers vary, with lung, urinary bladder or liver in first place, while for females throughout the region breast cancer is the greatest problem. In both sexes, non-Hodgkins lymphomas and leukemias are relatively frequent, along with thyroid cancer in certain female populations. Adenocarcinomas of the breast, prostate and colorectum appear to be increasing. Coordination of activities within the Arab world could bring major benefits to cancer control in the eastern Mediterranean region.

  3. Building capacity for clinical research in developing countries: the INDOX Cancer Research Network experience. (United States)

    Ali, Raghib; Finlayson, Alexander; Indox Cancer Research Network


    Transnational Organisations increasingly prioritise the need to support local research capacity in low and middle income countries in order that local priorities are addressed with due consideration of contextual issues. There remains limited evidence on the best way in which this should be done or the ways in which external agencies can support this process.We present an analysis of the learning from the INDOX Research Network, established in 2005 as a partnership between the Institute of Cancer Medicine at the University of Oxford and India's top nine comprehensive cancer centres. INDOX aims to enable Indian centres to conduct clinical research to the highest international standards; to ensure that trials are developed to address the specific needs of Indian patients by involving Indian investigators from the outset; and to provide the training to enable them to design and conduct their own studies. We report on the implementation, outputs and challenges of simultaneously trying to build capacity and deliver meaningful research output.

  4. Controllability in cancer metabolic networks according to drug targets as driver nodes. (United States)

    Asgari, Yazdan; Salehzadeh-Yazdi, Ali; Schreiber, Falk; Masoudi-Nejad, Ali


    Networks are employed to represent many nonlinear complex systems in the real world. The topological aspects and relationships between the structure and function of biological networks have been widely studied in the past few decades. However dynamic and control features of complex networks have not been widely researched, in comparison to topological network features. In this study, we explore the relationship between network controllability, topological parameters, and network medicine (metabolic drug targets). Considering the assumption that targets of approved anticancer metabolic drugs are driver nodes (which control cancer metabolic networks), we have applied topological analysis to genome-scale metabolic models of 15 normal and corresponding cancer cell types. The results show that besides primary network parameters, more complex network metrics such as motifs and clusters may also be appropriate for controlling the systems providing the controllability relationship between topological parameters and drug targets. Consequently, this study reveals the possibilities of following a set of driver nodes in network clusters instead of considering them individually according to their centralities. This outcome suggests considering distributed control systems instead of nodal control for cancer metabolic networks, leading to a new strategy in the field of network medicine.

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

  12. Cancer risk in older people receiving statin therapy: a meta-analysis of randomized controlled trials (United States)

    Liu, Hong-Wei; Bian, Su-Yan; Zhu, Qi-Wei; Zhao, Yue-Xiang


    Background Although statins are well tolerated by most aged people, their potential carcinogenicity is considered as one of the biggest factors limiting the use of statins. The aim of the present study was to determine the risk of cancer in people aged over 60 years receiving statin therapy. Methods A comprehensive search for articles published up to December 2015 was performed, reviews of each randomized controlled trials (RCTs) that compared the effects of statin mono-therapy with placebo on the risk of cancer in people aged > 60 years were conducted and data abstracted. All the included studies were evaluated for publication bias and heterogeneity. Pooled odds ratios (OR) estimates and 95% confidence intervals (CIs) were calculated using the random effects model. Results A total of 12 RCTs, involving 62,927 patients (31,517 in statin therapy group and 31,410 in control group), with a follow-up duration of 1.9–5.4 years, contributed to the analysis. The statin therapy did not affect the overall incidence of cancer (OR = 1.03, 95% CI: 0.94–1.14, P = 0.52); subgroup analyses showed that neither the variety nor the chemical properties of the statins accounted for the incidence of cancer in older people. Conclusions Our meta-analysis findings do not support a potential cancer risk of statin treatment in people over 60 years old. Further targeted researches with a longer follow-up duration are warranted to confirm this issue.

    Full Text Available Fatima Zahra Laamiri,1 Azzedine Otmani,2 Samir Ahid,1,3 Amina Barkat11Faculty of Medicine and Pharmacy/Research Team in Maternal and Child Health and Nutrition, Mohammed V-Souissi University, Rabat, Morocco; 2National Institute of Oncology, Rabat, Morocco; 3Pharmacy Unit, National Institute of Oncology, Rabat, MoroccoBackground: Breast cancer has become the most common type of cancer in Morocco. In 2005, 127 new cases in women, representing 33.5% of female cancers, were added to the National Center of Oncology registry. The incidence of breast cancer is higher in Morocco than in the three other Maghreb countries, and it is significantly lower than in Western countries where it stands at over 80 cases per 100,000 people.Purpose: This 2-year long case-control study was conducted to assess the causal relationship between the lipid profile of overweight Moroccan women and breast cancer risk.Patients and methods: Overweight female patients with breast cancer (n = 400 were compared to 400 healthy controls at the National Institute of Oncology of Rabat. The epidemiological data on the disease and physical activity were gathered by interviewing the patients who had their lipid profile measured (total cholesterol, triglycerides, high density lipoprotein cholesterol, and low density lipoprotein cholesterol. Body mass index was used to determine if patients were overweight.Results: Univariate analysis revealed a significant association between breast cancer and high body mass index (odds ratio [OR] = 1.31; 95% confidence interval [CI] = 1.25–1.37, menopause (OR = 2.68; 95% CI = 2–3.55, lack of physical activity (OR = 0.26; 95% CI = 0.21–0.31, and triglyceridemia (OR = 3.78; 95% CI = 2.73–5.23.

    Full Text Available With rapid development of high-throughput techniques and accumulation of big transcriptomic data, plenty of computational methods and algorithms such as differential analysis and network analysis have been proposed to explore genome-wide gene expression characteristics. These efforts are aiming to transform underlying genomic information into valuable knowledges in biological and medical research fields. Recently, tremendous integrative research methods are dedicated to interpret the development and progress of neoplastic diseases, whereas differential regulatory analysis (DRA based on gene coexpression network (GCN increasingly plays a robust complement to regular differential expression analysis in revealing regulatory functions of cancer related genes such as evading growth suppressors and resisting cell death. Differential regulatory analysis based on GCN is prospective and shows its essential role in discovering the system properties of carcinogenesis features. Here we briefly review the paradigm of differential regulatory analysis based on GCN. We also focus on the applications of differential regulatory analysis based on GCN in cancer research and point out that DRA is necessary and extraordinary to reveal underlying molecular mechanism in large-scale carcinogenesis studies.

  20. Cervical cancer control in India: taking evidence to action. (United States)

    Farooqui, Habib Hasan; Zodpey, Sanjay


    The most prevalent types of human papillomavirus in cervical cancer in India are HPV 16 and HPV 18, found in 60.7 per cent and 16 per cent of cases respectively. A comprehensive strategy with a judicious mix of interventions on health promotion, specific protection (vaccination), early diagnosis (screening), and treatment should be instituted to prevent and control cervical cancer in India. Proponents of vaccination and screening argue for enhanced investments on these interventions based on their relative cost-effectiveness. For policymakers, the major concerns about these interventions remain affordability and cost to government. Herein we try to review comprehensively the evidence on prevention and control interventions and to recommend appropriate policies to guide public health decision-making.

    Because of the ability of integrating the strengths of different modalities and providing fully integrated information, multi-modality molecular imaging techniques provide an excellent solution to detecting and diagnosing earlier cancer, which remains difficult to achieve by using the existing techniques. In this paper, we present an overview of our research efforts on the development of the optical imaging-centric multi-modality molecular imaging platform, including the development of the imaging system, reconstruction algorithms and preclinical biomedical applications. Primary biomedical results show that the developed optical imaging-centric multi-modality molecular imaging platform may provide great potential in the preclinical biomedical applications and future clinical translation.

    This randomized controlled clinical study aimed to determine the effect of 2 foot massage methods on symptom control in people with colorectal cancer who received chemoradiotherapy. Data were collected between June 16, 2015, and February 10, 2016, in the Department of Radiation Oncology of an oncology training and research hospital. The sample comprised 60 participants. Data were collected using an introductory information form, common terminology criteria for adverse events and European Organization for Research and Treatment of Cancer Quality of Life Questionnaires C30 and CR29. Participants were randomly allocated to 3 groups: classical foot massage, reflexology, and standard care control. The classical massage group received foot massage using classical massage techniques, and the reflexology group received foot reflexology focusing on symptom-oriented reflexes twice a week during a 5-week chemoradiotherapy treatment schedule. The control group received neither classical massage nor reflexology. All patients were provided with the same clinic routine care. The classical massage was effective in reducing pain level and distension incidence while foot reflexology was effective in reducing pain and fatigue level, lowering incidence of distension and urinary frequency and improving life quality.

Interface weighted least squares estimation procedures with control logic were developed using either optimal regulator theory or with control logic based upon single stage performance indices.

  6. Evaluation of a community-academic partnership: lessons from Latinos in a network for cancer control. (United States)

    Corbin, J Hope; Fernandez, Maria E; Mullen, Patricia D


    Established in 2002, Latinos in a Network for Cancer Control is a community-academic network supported by the Centers for Disease Control and Prevention and the National Cancer Institute. The network includes >130 individuals from 65 community and academic organizations committed to reducing cancer-related health disparities. Using an empirically derived systems model--the Bergen Model of Collaborative Functioning--as the analytic frame, we interviewed 19 partners to identify challenges and successful processes. Findings indicated that sustained partner interaction created "meaningful relationships" that were routinely called on for collaboration. The leadership was regarded positively on vision, charisma, and capacity. Limitations included overreliance on a single leader. Suggestions supported more delegation of decision making, consistent communication, and more equitable resource distribution. The study highlighted new insights into dynamics of collaboration: Greater inclusiveness of inputs (partners, finances, mission) and loosely defined roles and structure produced strong connections but less network-wide productivity (output). Still, this profile enabled the creation of more tightly defined and highly productive subgroups, with clear goals and roles but less inclusive of inputs than the larger network. Important network outputs included practice-based research publications, cancer control intervention materials, and training to enhance the use of evidence-based interventions, as well as continued and diversified funding.

  8. Endomembrane control of cell polarity: Relevance to cancer. (United States)

    Baschieri, Francesco; Farhan, Hesso


    The role of polarity in cancer is an emerging research area and loss of polarity is widely considered an important event in cancer. Among the polarity regulating molecules, the small GTPase Cdc42 was extensively studied. Most attention was given to Cdc42 signaling at the plasma membrane, but whether and how Cdc42 is regulated at endomembranes remained poorly understood. Moreover, whether the endomembrane pool of Cdc42 is of any relevance to cell polarity was unknown. In our recent work, we identified a complex between the Golgi matrix protein GM130 and RasGRF and showed that it is responsible for regulating the Golgi pool of Cdc42, but had no effect on the plasma membrane pool of Cdc42. Depletion of GM130 disrupted apico-basal polarity as well as front-rear polarity, indicating that the spatial pool of Cdc42 is functionally relevant. The biomedical relevance of this finding was supported by the observation than GM130 is progressively lost in colorectal cancer. These findings support a role of the endomembrane pool of Cdc42 in cell polarity and point to a potential role of alterations of this pool in cancer.

    Rodriguez, Juan L; Thomas, Cheryll C; Massetti, Greta M; Duquette, Debra; Avner, Lindsay; Iskander, John; Khoury, Muin J; Richardson, Lisa C


    Although many efforts in cancer prevention and control have routinely focused on behavioral risk factors, such as tobacco use, or on the early detection of cancer, such as colorectal cancer screening, advances in genetic testing have created new opportunities for cancer prevention through evaluation of family history and identification of cancer-causing inherited mutations. Through the collection and evaluation of a family cancer history by a trained health care provider, patients and families at increased risk for a hereditary cancer syndrome can be identified, referred for genetic counseling and testing, and make informed decisions about options for cancer risk reduction (1). Although hereditary cancers make up a small proportion of all cancers, the number of affected persons can be large, and the level of risk among affected persons is high. Two hereditary cancer syndromes for which public health professionals have worked to reduce the burden of morbidity and mortality are hereditary breast and ovarian cancer syndrome (HBOC) and Lynch syndrome.

    Tania Lahera-Sánchez


    Full Text Available The tissue microarray (TMA technique is based on making cylindrical cores from paraffin donor blocks and transfer to a single recipient block. The TMA has revolutionized the field of pathology for the possibility to evaluate multiple samples in one slide. There is no precedent of this subject in Cuba, so the objective of this research was to implement the TMA technique. The concordance of the results obtained by complete section and the TMA were evaluated for this purpose, in the evaluation of the estrogen receptors (ER, progesterone (PR and epidermal growth factor type 2 (HER2 in samples of breast cancer. Forty-five paraffin-embedded samples from women diagnosed with breast cancer at the Institute of Oncology in 2012 were studied. Two TMA blocks were constructed, and subsequently the expression of markers ER, PR and HER2 was determined by immunohistochemistry, in the complete section of tissue and in the TMA. Kappa index was used for concordance analysis. A good concordance was obtained for all three markers (ER k=0.8272; PR k=0.793 and HER2 k=0.716. This study constitutes the first report on the TMA technique in Cuba and shows that it is a valuable tool, suggesting its potential use in translational research and clinical trials on vaccines.

  12. Stem cell research: paths to cancer therapies and regenerative medicine. (United States)

    Weissman, Irving


    Most tissues in complex metazoans contain a rare subset of cells that, at the single-cell level, can self-renew and also give rise to mature daughter cells. Such stem cells likely in development build tissues and are retained in adult life to regenerate them. Cancers and leukemias are apparently not an exception: rare leukemia stem cells and cancer stem cells have been isolated that contain all of the tumorigenicity of the whole tumor, and it is their properties that will guide future therapies. None of this was apparent just 20 years ago, yet this kind of stem cell thinking already provides new perspectives in medical science and could usher in new therapies. Today, political, religious, and ethical issues surround embryonic stem cell and patient-specific pluripotent stem cell research and are center stage in the attempts by governments to ban these fields for discovery and potential therapies. These interventions require physicians and physician-scientists to determine for themselves whether patient welfare or personal ethics will dominate in their practices, and whether all aspects of stem cell research can be pursued in a safe and regulated fashion.

    Survivors of childhood cancer carry a substantial burden of morbidity and are at increased risk for premature death. Furthermore, clear associations exist between specific therapeutic exposures and the risk for a variety of long-term complications. The entire landscape of health issues encountered for decades after successful completion of treatment is currently being explored in various collaborative research settings. These settings include large population-based or multi-institutional cohorts and single-institution studies. The ascertainment of outcomes has depended on self-reporting, linkage to registries, or clinical assessments. Survivorship research in the cooperative group setting, such as the Children's Oncology Group, has leveraged the clinical trials infrastructure to explore the molecular underpinnings of treatment-related adverse events, and to understand specific complications in the setting of randomized risk-reduction strategies. This review highlights the salient findings from these large collaborative initiatives, emphasizing the need for life-long follow-up of survivors of childhood cancer, and describing the development of several guidelines and efforts toward harmonization. Finally, the review reinforces the need to identify populations at highest risk, facilitating the development of risk prediction models that would allow for targeted interventions across the entire trajectory of survivorship.

  14. Public involvement in breast cancer research: an analysis and model for future research. (United States)

    McCormick, Sabrina; Brody, Julia; Brown, Phil; Polk, Ruth


    Public involvement in health program planning has been taking place for many years, and has provided a precedent for the emergence of public involvement in research conducted since the early 1990s. Such involvement is now widely seen in breast cancer research, due to the large public concern and major social movement activity. This article reviews current practices and general models of public involvement in research and constructs a prototype. The authors interviewed researchers, program officers, and laypeople in order to understand the obstacles, processes, and benefits. They conclude that public involvement has major ramifications for the democratization of science and the construction of knowledge by teaching lay people about science and sensitizing researchers to concerns of the public. There is growing support on the part of scientists and government agents for public involvement.

  15. Prevalence and contribution of BRCA1 mutations in breast cancer and ovarian cancer: Results from three US population-based case-control studies of ovarian cancer

    Energy Technology Data Exchange (ETDEWEB)

    Whittemore, A.S.; Gong, G.; Itnyre, J. [Stanford Univ. School of Medicine, CA (United States)


    We investigate the familial risks of cancers of the breast and ovary, using data pooled from three population-based case-control studies of ovarian cancer that were conducted in the United States. We base estimates of the frequency of mutations of BRCA1 (and possibly other genes) on the reported occurrence of breast cancer and ovarian cancer in the mothers and sisters of 922 women with incident ovarian cancer (cases) and in 922 women with no history of ovarian cancer (controls). Segregation analysis and goodness-of-fit testing of genetic models suggest that rare mutations (frequency .0014; 95% confidence interval .0002-.011) account for all the observed aggregation of breast cancer and ovarian cancer in these families. The estimated risk of breast cancer by age 80 years is 73.5% in mutation carriers and 6.8% in noncarriers. The corresponding estimates for ovarian cancer are 27.8% in carriers and 1.8% in noncarriers. For cancer risk in carriers, these estimates are lower than those obtained from families selected for high cancer prevalence. The estimated proportion of all U.S. cancer diagnoses, by age 80 years, that are due to germ-line BRCA1 mutations is 3.0% for breast cancer and 4.4% for ovarian cancer. Aggregation of breast cancer and ovarian cancer was less evident in the families of 169 cases with borderline ovarian cancers than in the families of cases with invasive cancers. Familial aggregation did not differ by the ethnicity of the probands, although the number of non-White and Hispanic cases (N = 99) was sparse. 14 refs., 3 figs., 6 tabs.

    Millions of people worldwide are exposed to arsenic in drinking water. The International Agency for Research on Cancer has concluded that ingested arsenic causes lung, bladder, and skin cancer. However, a similar conclusion was not made for kidney cancer because of a lack of research with individual data on exposure and dose-response. With its unusual geology, high exposures, and good information on past arsenic water concentrations, northern Chile is one of the best places in the world to investigate the carcinogenicity of arsenic. We performed a case-control study in 2007-2010 of 122 kidney cancer cases and 640 population-based controls with individual data on exposure and potential confounders. Cases included 76 renal cell, 24 transitional cell renal pelvis and ureter, and 22 other kidney cancers. For renal pelvis and ureter cancers, the adjusted odds ratios by average arsenic intakes of 1,000 µg/day (median water concentrations of 60, 300, and 860 µg/L) were 1.00, 5.71 (95% confidence interval: 1.65, 19.82), and 11.09 (95% confidence interval: 3.60, 34.16) (Ptrend water arsenic causes renal pelvis and ureter cancer.

    Cervical cancer (CC) is second most common cause of cancer in Latin America and is a leading cause of cancer mortality among women. In 2015, an estimated 74,488 women will be diagnosed with CC in Latin America and 31,303 will die of the disease. CC mortality is projected to increase by 45% by 2030 despite human papillomavirus (HPV) vaccination and screening efforts. In this setting, the goal was of the current study was to examine CC control efforts in Latin America and identify deficiencies in these efforts that could be addressed to reduce CC incidence and mortality. The authors found that HPV vaccination has been introduced in the majority of Latin American countries, and there is now a need to monitor the success (or shortcomings) of these programs and to ensure that these programs are sustainable. This topic was also reviewed in light of emerging data demonstrating that visual inspection with acetic acid and HPV DNA testing without Papanicolaou tests have efficacy from a screening perspective and are good alternatives to cytology-based screening programs. Overall, there is a need to build capacity for CC control in Latin America and the best strategy will depend on the country/region and must be tailored to meet the needs of the population as well as available resources.

  18. Assessing tobacco use by cancer patients and facilitating cessation: an American Association for Cancer Research policy statement. (United States)

    Toll, Benjamin A; Brandon, Thomas H; Gritz, Ellen R; Warren, Graham W; Herbst, Roy S


    When diagnosed with cancer, patients can immediately make a meaningful positive impact on their health by stopping their tobacco use. Scientific evidence clearly shows that tobacco use in patients with cancer leads to poorer outcomes. The specific biological processes driving tobacco consumption's interference in cancer therapy are the subject of continuing research, but the evidence is clear that tobacco use in patients with cancer leads to decreased treatment efficacy and safety, decreased survival, decreased quality of life, increased treatment-related toxicity, and increased risk of cancer recurrence and second primary tumors. Data suggest that tobacco cessation can improve outcomes and survival in patients with cancer, yet full execution of evidence-based cessation interventions is infrequent in oncology settings. Therefore, both improved provision of cessation assistance to all patients with cancer who use tobacco or have recently quit and further study of the deleterious effects of tobacco use and benefits of tobacco cessation on cancer progression and treatment are needed and recommended by the American Association for Cancer Research. Progress on both fronts begins with universal assessment and documentation of tobacco use as a standard of quality cancer care regardless of treatment setting and will be further facilitated through the development of reliable, valid, and standard measures of tobacco use, incorporation of evidence-based procedures into quality and accreditation procedures, and the development of appropriate training, clinical infrastructure, and incentives for delivery of tobacco cessation interventions.

    AIM: Tumor formation is generally linked to an expansion of glycolytic phosphometabolite pools and aerobic glycolytic flux rates. To achieve this, tumor cells generally overexpress a special glycolytic isoenzyme, termed pyruvate kinase type M2. The present study was designed to evaluate the use of a new tumor marker, tumor M2-PK, in discriminating gastrointestinal cancer patients from healthy controls, and to compare with the reference tumor markers CEA and CA72-4.METHODS: The concentration of tumor M2-PK in body fluids could be quantitatively determined by a commercially available enzyme-linked immunosorbent assay (ELISA)-kit (ScheBo(R) Tech, Giessen, Germany). By using this kit, the tumor M2-PK concentration was measured in EDTA-plasma of 108 patients. For the healthy blood donors a cut-off value of 15 U/mL was evaluated, which corresponded to 90% specificity. Overall 108 patients were included in this study, 54 patients had a histological confirmed gastric cancer, 54 patients colorectal cancer, and 20 healthy volunteers served as controls.RESULTS: The cut-off value to discriminate patients from controls was established at 15 U/mL for tumor M2-PK. The mean tumor M2-PK concentration of gastric cancer was 26.937 U/mL. According to the TNM stage system, the mean tumor M2-PK concentration of stage Ⅰ was 16.324 U/mL, of stage Ⅱ 15.290 U/mL, of stage Ⅲ 30.289 U/mL, of stage Ⅳ127.31 U/mL, of non-metastasis 12.854 U/mL and of metastasis 35.711 U/mL. The mean Tumor M2-PK concentration of colorectal cancer was 30.588 U/mL. According to the Dukes stage system, the mean tumor M2-PK concentration of Dukes A was 16.638 U/mL, of Dukes B 22.070 U/mL, and of Dukes C 48.024 U/mL, of non-metastasis 19.501 U/mL, of metastasis 49.437 U/mL. The mean tumor M2-PK concentration allowed a significant discrimination of colorectal cancers (30.588 U/mL) from controls (10.965 U/mL) (P<0.01), and gastric cancer (26.937 U/mL) from controls (10.965 U/mL)(P<0.05).

    Full Text Available Coated magnetite nanoparticles were linked to 68Ga complexes used in the positron emission tomography (PET for a new technical approach to detect cancer tissue with radiopharmaceuticals. By substitution of the Ga isotope with an alpha emitter the same compound could be used for cancer treatment. Furthermore the nanoparticles were connected to pH-sensitive complexes, enabling a pH-controlled assembly/disassembly and therefore the spreading of the particles in the tissue. With this novel method of combining detection and treatment simultaneously, the amount of medical exposure could be minimized for the patient. The results demonstrate that magnetite nanoparticles can effectively be functionalized with PET isotopes and pH sensitive complexes in order to use them as a new type of radiopharmaceuticals.

  5. Cancer registration, public health and the reform of the European data protection framework: Abandoning or improving European public health research? (United States)

    Andersen, Mette Rye; Storm, Hans H


    The importance of cancer- and other disease registries for planning, management and evaluation of healthcare systems has been shown repeatedly during the last 50 years. Complete and unbiased population-level analyses on routinely collected, individual data concerning health and personal characteristics can address significant concerns about risk factors for cancer and provide sound evidence about public health and the effectiveness of healthcare systems. The existence of quality controlled and comprehensive data in registries, allowed to be used for quality control, research and public health purposes are taken as granted by most health professionals and researchers. However, the current revision of the European Union (EU) data protection framework suggests a harmonisation of requirements for confidentiality and individual consent to data processing, likely at the expense of proper use of registry data in the health sector. Consequences of excessive confidentiality rules that may lead to missed data linkages have been simulated. The simulations provide one possible explanation for observed heterogeneity among some cancer incidence data. Further, public health, quality control and epidemiological research on large populations can no longer provide evidence for health interventions, if requirements for consent renders research impossible or where attempts to obtain consent from each data subject generates biased results. Health professionals should engage in the on-going debate on the Commission's proposal for a General Data Protection Regulation. The nature and use of registry data in public health research must be explained and known to policy-makers and the public. Use of cancer registry data and other epidemiological activity will terminate abruptly if an unnecessarily strict EU data protection regulation is adopted. Research based interventions, as well as the international recognised standing of cancer registries and register-based research institutions in

    Marcus, Alfred C; Diefenbach, Michael A; Stanton, Annette L; Miller, Suzanne M; Fleisher, Linda; Raich, Peter C; Morra, Marion E; Perocchia, Rosemarie Slevin; Tran, Zung Vu; Bright, Mary Anne


    The authors describe 3 large randomized trials from the Cancer Information Service Research Consortium. Three web-based multimedia programs are being tested to help newly diagnosed prostate (Project 1) and breast cancer patients (Project 2) make informed treatment decisions and breast cancer patients prepare for life after treatment (Project 3). Project 3 also tests a telephone callback intervention delivered by a cancer information specialist. All participants receive standard print material specific to each project. Preliminary results from the 2-month follow-up interviews are reported for the initial wave of enrolled participants, most of whom were recruited from the Cancer Information Service (1-800-4-CANCER) telephone information program (Project 1: n =208; Project 2: n =340; Project 3: n =792). Self-reported use of the multimedia program was 51%, 52%, and 67% for Projects 1, 2, and 3, respectively. Self-reported use of the print materials (read all, most, or some) was 90%, 85%, and 83% for Projects 1, 2, and 3, respectively. The callback intervention was completed by 92% of Project 3 participants. Among those using the Cancer Information Service Research Consortium interventions, perceived usefulness and benefit was high, and more than 90% reported that they would recommend them to other cancer patients. The authors present 5 initial lessons learned that may help inform future cancer communications research.

    Full Text Available Objective: A common disorder requiring symptom palliation in palliative and end-of-life care is cancer. Cancer pain is recognized as a global health burden. This paper sought to systematically examine the extent to which there is an adequate scientific research base on cancer pain and its reporting characteristics in the palliative care journal literature. Materials and Methods: Search conducted in MEDLINE and CINAHL sought to locate all studies published in 19 palliative/ hospice/ supportive/ end-of-life care journals from 2009 to 2010. The journals included were: American Journal of Hospice and Palliative Care, BMC Palliative Care, Current Opinion in Supportive and Palliative Care, End of Life Care Journal, European Journal of Palliative Care, Hospice Management Advisor, Indian Journal of Palliative Care, International Journal of Palliative Nursing, Internet Journal of Pain Symptom Control and Palliative Care, Journal of Pain and Palliative Care Pharmacotherapy, Journal of Palliative Care, Journal of Palliative Medicine, Journal of Social Work in End-of-life and Palliative Care, Journal of Supportive Oncology, Palliative Medicine, Palliative and Supportive Care, and Supportive Care in Cancer. Journal contents were searched to identify studies that included cancer pain in abstract. Results: During the years 2009 and 2010, of the selected 1,569 articles published in the journals reviewed, only 5.86% (92 articles were on cancer pain. Conclusion: While researchers in the field of palliative care have studied cancer pain, the total percentage for studies is still a low 5.86%. To move the field of palliative care forward so that appropriate guidelines for cancer pain management can be developed, it is critical that more research be reported upon which to base cancer pain therapy in an evidence-based palliative care model.

    Since digital control systems were introduced to the market more than 30 years ago, the operational efficiency and stability gained through their use have fueled our migration and ultimate dependence on them for the monitoring and control of critical infrastructure. While these systems have been designed for functionality and reliability, a hostile cyber environment and uncertainties in complex networks and human interactions have placed additional parameters on the design expectations for control systems.

  13. Human papillomavirus and cancer prevention: gaps in knowledge and prospects for research, policy, and advocacy. (United States)

    Franco, Eduardo L; de Sanjosé, Silvia; Broker, Thomas R; Stanley, Margaret A; Chevarie-Davis, Myriam; Isidean, Sandra D; Schiffman, Mark


    The recognition that human papillomavirus (HPV) infection is the central, necessary cause of cervical cancer paved the way to new fronts of prevention via improved screening methods and HPV vaccination. Much has been learned in all fronts, from the molecular basis of our understanding of how HPV causes disease to the health economics of preventive strategies at the individual and population levels. Progress in other areas of cancer control has yet to show the same multi- and trans-disciplinary gains seen in research on HPV-associated malignancies, which is one of the unequivocal success stories in disease prevention. Yet, as an embarrassment of riches, much more research is needed to fill the gaps in knowledge that remain before we are able to reap the benefits from the knowledge translation from all fronts. Public health research on setting-specific implementation of HPV-based preventive strategies and more concerted advocacy to counter barriers facing the adoption of these strategies are likely to yield major dividends in reducing the burden of HPV-associated diseases. This article forms part of a special supplement entitled "Comprehensive Control of HPV Infections and Related Diseases" Vaccine Volume 30, Supplement 5, 2012.

  15. An implementation science perspective on psychological science and cancer: what is known and opportunities for research, policy, and practice. (United States)

    Rabin, Borsika; Glasgow, Russell E


    We discuss the role of implementation science in cancer and summarize the need for this perspective. Following a summary of key implementation science principles and lessons learned, we review the literature on implementation of cancer prevention and control activities across the continuum from prevention to palliative care. We identified 10 unique relevant reviews, four of which were specific to cancer. Multicomponent implementation strategies were found to be superior to single-component interventions, but it was not possible to draw conclusions about specific strategies or the range of conditions across which strategies were effective. Particular gaps identified include the need for more studies of health policies and reports of cost, cost-effectiveness, and resources required. Following this review, we summarize the types of evidence needed to make research findings more actionable and discuss emerging implementation science opportunities for psychological research on cancer prevention and control. These include innovative study designs (i.e., rapid learning designs, simulation modeling, comparative effectiveness, pragmatic studies, mixed-methods research) and measurement science (i.e., development of context-relevant measures; practical, longitudinal measures to gauge improvement; cost-effectiveness data; and harmonized patient report data). We conclude by identifying a few grand challenges for psychologists that if successfully addressed would accelerate integration of evidence into cancer practice and policy more consistently and rapidly.

    As the number of cancer survivors continues to grow, research investigating the factors that affect cancer outcomes, such as disease recurrence, risk of second malignant neoplasms, and the late effects of cancer treatments, becomes ever more important. Numerous epidemiologic studies have investigated factors that affect cancer risk, but far fewer have addressed the extent to which demographic, lifestyle, genomic, clinical, and psychosocial factors influence cancer outcomes. To identify research priorities as well as resources and infrastructure needed to advance the field of cancer outcomes and survivorship research, the National Cancer Institute sponsored a workshop titled "Utilizing Data from Cancer Survivor Cohorts: Understanding the Current State of Knowledge and Developing Future Research Priorities" on November 3, 2011, in Washington, DC. This commentary highlights recent findings presented at the workshop, opportunities to leverage existing data, and recommendations for future research, data, and infrastructure needed to address high priority clinical and research questions. Multidisciplinary teams that include epidemiologists, clinicians, biostatisticians, and bioinformaticists will be essential to facilitate future cancer outcome studies focused on improving clinical care of cancer patients, identifying those at high risk of poor outcomes, and implementing effective interventions to ultimately improve the quality and duration of survival.

  17. Growth Analysis of Cancer Biology Research, 2000-2011

    Directory of Open Access Journals (Sweden)



    Full Text Available Methods and Material: The PubMed database was used for retrieving data on 'cancer biology.' Articles were downloaded from the years 2000 to 2011. The articles were classified chronologically and transferred to a spreadsheet application for analysis of the data as per the objectives of the study. Statistical Method: To investigate the nature of growth of articles via exponential, linear, and logistics tests. Result: The year wise analysis of the growth of articles output shows that for the years 2000 to 2005 and later there is a sudden increase in output, during the years 2006 to 2007 and 2008 to 2011. The high productivity of articles during these years may be due to their significance in cancer biology literature, having received prominence in research. Conclusion: There is an obvious need for better compilations of statistics on numbers of publications in the years from 2000 to 2011 on various disciplines on a worldwide scale, for informed critical assessments of the amount of new knowledge contributed by these publications, and for enhancements and refinements of present Scientometric techniques (citation and publication counts, so that valid measures of knowledge growth may be obtained. Only then will Scientometrics be able to provide accurate, useful descriptions and predictions of knowledge growth.

    Qiu, Yan-fang; Liu, Zhi-gang; Yang, Wen-juan; Zhao, Yu; Tang, Jiao; Tang, Wei-zhi; Jin, Yi; Li, Fang; Zhong, Rui; Wang, Hui


    Small cell lung cancer (SCLC) accounts for approximately 10-15% of all lung cancers. No significant improvement has been made for patients with SCLC in the past several decades. The main progresses were the thoracic radiation and prophylactic cranial irradiation (PCI) that improved the patient survival rate. For patients with limited disease and good performance status (PS), concurrent chemoradiotherapy (CCRT) followed by PCI should be considered. For extensive disease, the combination of etoposide and platinum-based chemotherapy remains the standard treatment and consolidative thoracic radiotherapy is beneficial for patients who have a significant respond to initial chemotherapy. However, the prognosis still remains poor. Recently, efforts have been focused on molecular targets and immunotherapy. But numerous molecular targets methods have failed to show a significant clinical benefit in patients with SCLC. It is anticipated that further development of research will depend on the on-going trials for molecular targeted therapy and immunotherapy which are promising and may improve the outcomes for SCLC in the next decade.

  19. A Framework for Training Transdisciplinary Scholars in Cancer Prevention and Control. (United States)

    James, Aimee S; Gehlert, Sarah; Bowen, Deborah J; Colditz, Graham A


    Traditionally, postdoctoral training programs largely have focused efforts within a single discipline or closely related fields. Yet, addressing the complex questions around cancer prevention and control increasingly requires the ability to work and communicate across disciplines in order to gain a perspective that encompasses the multilevel and multifaceted issues involved with this public health issue. To address this complexity, a transdisciplinary training program was implemented to cultivate the professional and scientific development of the postdoctoral fellows in Washington University in St Louis School of Medicine's Division of Public Health Sciences and NCI-funded centers (Community Networks Program Center and Transdisciplinary Research in Energetics in Cancer Center). Fellows are matched with primary mentors and assemble a multidisciplinary mentoring team. Structured programs support the transition of fellows from disciplinary trainees to independent transdisciplinary scholars and provide exposure to multiple disciplines. This article describes the training program, challenges encountered in implementation, solutions to those problems, and the metrics employed to evaluate the program's success. The goal of the program is to train emerging investigators in the conceptual bases, language, and practices that underlie a transdisciplinary perspective on cancer prevention and control research, to create an infrastructure for continued cross-discipline dialogue and collaboration, and to develop disseminable strategies for such training.

    Although the incidence of cancer and cancer related deaths in the United States has decreased over the past two decades due to improvements in early detection and treatment, cancer still is responsible for a quarter of the deaths in this country. There is much room for improvement on the standard treatments currently available and the National Cancer Institute (NCI) has recognized the potential for nanotechnology and nanomaterials in this area. The NCI Alliance for Nanotechnology in Cancer was formed in 2004 to support multidisciplinary researchers in the application of nanotechnology to cancer diagnosis and treatment. The researchers in the Alliance have been productive in generating innovative solutions to some of the central issues of cancer treatment including how to detect tumors earlier, how to target cancer cells specifically, and how to improve the therapeutic index of existing chemotherapies and radiotherapy treatments. Highly creative ideas are being pursued where novelty in nanomaterial development enables new modalities of detection or therapy. This review highlights some of the innovative materials approaches being pursued by researchers funded by the NCI Alliance.

    Desmond, Renee A; Chapman, Kathryn; Graf, Gavin; Stanfield, Bret; Waterbor, John W


    The Alabama Comprehensive Cancer Control Coalition (ACCCC) has developed an integrated and coordinated approach to reducing cancer incidence, morbidity, and mortality, and to improving the quality of life for cancer survivors, their families, and their caregivers. The ACCCC is currently in a maintenance phase and a formal plan for sustainability of the coalition was needed to keep the members engaged and productive. A training session in coalition sustainability conducted in 2013 identified the following elements as essential to success: (1) increased marketing of the coalition by simplifying its mission; (2) improved networking including flexibility in coalition meeting location and attendance; (3) increased membership satisfaction through transformational leadership; (4) revision of the working structure of committees and improved accountability; and (5) enhancement of partner satisfaction with coalition activities designed to recruit and retain new partners. A self-administered membership satisfaction survey was given to assess coalition mission, meeting logistics, organization, capacity building, and coalition goals. Results indicated that the subcategories of communication, mission, and meeting logistics were rated satisfied to very satisfied on a five-point scale. Although the ACCCC had clearly written goals, improvement could be made in leadership participation and new member orientation could be improved. Most members rated their parent organization as highly involved with the ACCCC and many offered suggestions on capacity building. Results of the sustainability training have clarified the ACCCC's plans to ensure coalition viability and improve strategies to inform stakeholders of the benefits of participation in the coalition.

  7. Stakeholder engagement for comparative effectiveness research in cancer care: experience of the DEcIDE Cancer Consortium. (United States)

    Greenberg, Caprice C; Wind, Jennifer K; Chang, George J; Chen, Ronald C; Schrag, Deborah


    Stakeholder input is a critical component of comparative effectiveness research. To ensure that the research activities of the Developing Evidence to Inform Decisions about Effectiveness (DEcIDE) Network, supported by the Agency for Healthcare Research and Quality, translate into the greatest impact for everyday practice and policy-making in cancer, we were tasked with soliciting stakeholder input regarding priority areas in cancer-related comparative effectiveness research for the DEcIDE Cancer Consortium. Given the increasing emphasis on stakeholder engagement in research, many investigators are facing a similar task, yet there is limited literature to guide such efforts, particularly in cancer care. To help fill this gap, we present our approach to operationalizing stakeholder engagement and discuss it in the context of other recent developments in the area. We describe challenges encountered in convening stakeholders from multiple vantage points to prioritize topics and strategies used to mitigate these barriers. We offer several recommendations regarding how to best solicit stakeholder input to inform comparative effectiveness research in cancer care. These recommendations can inform other initiatives currently facing the challenges of engaging stakeholders in priority setting for cancer.

    A Virtual Accelerator is a computer process which simulates behavior of beam in an accelerator and responds to the accelerator control program under development in a same way as an actual accelerator. To realize Virtual Accelerator, control system should provide the same program interface to top layer Application Control Program, it can make 'Real Accelerator' and 'Virtual Accelerator'use the same GUI, so control system should have a layer to hide hardware details, Application Control Program access control devices through logical name but not through coded hardware address. Without this layer, it is difficult to develop application program which can access both 'Virtual' and 'Real' Accelerators using same program interfaces. For this reason, we can create CSR Runtime Database which allows application program to access hardware devices and data on a simulation process in a unified way. A device 'is represented as a collection of records in CSR Runtime Database. A control program on host computer can access devices in the system only through names of record fields, called channel.

    AIM:To investigate barriers to colorectal cancer (CRC) screening in a community population. METHODS:We conducted a community-based case-control study in an urban Chinese population by questionnaire. Cases were selected from those completing both a fecal occult blood test (FOBT) case and colonoscopy in a CRC screening program in 2004. Control groups were matched by gender, age group and community. Control 1 included those having a positive FOBT but refusing a colonoscopy. Control 2 included those who refused both an FOBT and colonoscopy. RESULTS:The impact of occupation on willingness to attend a colorectal screening program differed by gender. P for heterogeneity was 0.009 for case vs control group 1, 0.01 for case versus control group 2, and 0.80 for control group 1 vs 2. Poor awareness of CRC and its screening program, characteristics of screening tests, and lack of time affected the screening rate. Financial support, fear of pain and bowel preparation were barriers to a colonoscopy as a screening test. Eighty-two percent of control group 1 and 87.1% of control group 2 were willing attend if the colonoscopy was free, but only 56.3% and 53.1%,respectively, if it was self-paid. Multivariate odds ratios for case vs control group 1 were 0.10 among those unwilling to attend a free colonoscopy and 0.50 among those unwilling to attend a self-paid colonoscopy. CONCLUSION:Raising the public awareness of CRC and its screening, integrating CRC screening into the health care system, and using a painless colonoscopy would increase its screening rate.

  10. [The application of CRISPR/Cas9 genome editing technology in cancer research]. (United States)

    Wang, Dayong; Ma, Ning; Hui, Yang; Gao, Xu


    The CRISPR/Cas9 (clustered regularly interspaced short palindromic repeats/CRISPR-associated protein-9 nuclease) genome editing technology has become more and more popular in gene editing because of its simple design and easy operation. Using the CRISPR/Cas9 system, researchers can perform site-directed genome modification at the base level. Moreover, it has been widely used in genome editing in multiple species and related cancer research. In this review, we summarize the application of the CRISPR/Cas9 system in cancer research based on the latest research progresses as well as our understanding of cancer research and genome editing techniques.

  18. Rac and Rho GTPases in cancer cell motility control

    Directory of Open Access Journals (Sweden)

    Parri Matteo


    Full Text Available Abstract Rho GTPases represent a family of small GTP-binding proteins involved in cell cytoskeleton organization, migration, transcription, and proliferation. A common theme of these processes is a dynamic reorganization of actin cytoskeleton which has now emerged as a major switch control mainly carried out by Rho and Rac GTPase subfamilies, playing an acknowledged role in adaptation of cell motility to the microenvironment. Cells exhibit three distinct modes of migration when invading the 3 D environment. Collective motility leads to movement of cohorts of cells which maintain the adherens junctions and move by photolytic degradation of matrix barriers. Single cell mesenchymal-type movement is characterized by an elongated cellular shape and again requires extracellular proteolysis and integrin engagement. In addition it depends on Rac1-mediated cell polarization and lamellipodia formation. Conversely, in amoeboid movement cells have a rounded morphology, the movement is independent from proteases but requires high Rho GTPase to drive elevated levels of actomyosin contractility. These two modes of cell movement are interconvertible and several moving cells, including tumor cells, show an high degree of plasticity in motility styles shifting ad hoc between mesenchymal or amoeboid movements. This review will focus on the role of Rac and Rho small GTPases in cell motility and in the complex relationship driving the reciprocal control between Rac and Rho granting for the opportunistic motile behaviour of aggressive cancer cells. In addition we analyse the role of these GTPases in cancer progression and metastatic dissemination.

  2. Prenatal DDT exposure and testicular cancer: a nested case-control study. (United States)

    Cohn, Barbara A; Cirillo, Piera M; Christianson, Roberta E


    The authors examined maternal serum levels of DDT-related compounds in relation to son's risk of testicular cancer 30 years later. Fifteen of 9,744 live-born sons were diagnosed with germ cell testicular cancer and had maternal serum samples. Cases were matched to three controls on race and birth year. Maternal serum DDT-related compounds, measured in the early postpartum, were associated with her son's risk of testicular cancer. Despite low statistical power, we observed that mothers of cases had a significantly higher ratio of p,p'-DDT (1,1,1-trichloro-2,2-bis(p-chlorophenyl)ethane) to p,p'-DDE (1,1'-dichloro-2,2'-bis(p-chlorophenyl)ethylene) and lower o,p'-DDT (1,1,1-tricholoro-2-(p-chlororphenyl)-2-(o-chlorophenyl)ethane). These findings are consistent with earlier exposure to DDT and with slower p,p'-DDT elimination among mothers of cases. Whether these associations could be direct, or operate via other pathways is unknown. Further research on interindividual differences in DDT metabolism could provide clues to testicular cancer etiology.

    The Japan National Committee for the Union for International Cancer Control (UICC) and UICC-Asia Regional Office (ARO) organized an international session as part of the official program of the 71st Annual Meeting of the Japanese Cancer Association to discuss the topic "Healthcare Economics: The Significance of the UN Summit non-communicable diseases (NCDs) Political Declaration in Asia." The presenters and participants discussed the growing cost of cancer in the Asian region and the challenges that are faced by the countries of Asia, all of which face budgetary and other systemic constraints in tackling and controlling cancer in the region. The session benefited from the participation of various stakeholders, including cancer researchers and representatives of the pharmaceutical industry. They discussed the significance of the UN Political Declaration on the prevention and control of NCDs (2011) as a means of boosting awareness of cancer in the Asian region and also addressed the ways in which stakeholders can cooperate to improve cancer control and treatment. Other issues that were covered included challenges relating to pharmaceutical trials in Asia and how to link knowledge and research outcomes. The session concluded with the recognition that with the onset of a super-aged society in most countries in Asia and an increasing focus on quality of life rather than quantity of life, it is more important than ever for all stakeholders to continue to share information and promote policy dialogue on cancer control and treatment.

  5. Prostate cancer chemoprevention in men of African descent: current state of the art and opportunities for future research. (United States)

    Chornokur, Ganna; Kumar, Nagi B


    Prostate cancer is the most frequently diagnosed malignancy in men. However, African American/Black men are 60 % more likely to be diagnosed with and 2.4 times more likely to die from prostate cancer, compared to Non-Hispanic White men. Despite the increased burden of this malignancy, no evidence-based recommendation regarding prostate cancer screening exists for the high-risk population. Moreover, in addition to screening and detection, African American men may constitute a prime population for chemoprevention. Early detection and chemoprevention may thus represent an integral part of prostate cancer control in this population. Importantly, recent research has elucidated biological differences in the prostate tumors of African American compared to European American men. The latter may enable a more favorable response in African American men to specific chemopreventive agents that target relevant signal transduction pathways. Based on this evolving evidence, the aims of this review are threefold. First, we aim to summarize the biological differences that were reported in the prostate tumors of African American and European American men. Second, we will review the single- and multi-target chemopreventive agents placing specific emphasis on the pathways implicated in prostate carcinogenesis. And lastly, we will discuss the most promising nutraceutical chemopreventive compounds. Our review underscores the promise of chemoprevention in prostate cancer control, as well as provides justification for further investment in this filed to ultimately reduce prostate cancer morbidity and mortality in this high-risk population of African American men.

  7. The Cervix Cancer Research Network (CCRN: Increasing access to cancer clinical trials in low- and middle-income countries

    Directory of Open Access Journals (Sweden)

    Gita eSuneja


    Full Text Available Introduction: The burden of cervical cancer is large and growing in developing countries, due in large part to limited access to screening services and lack of human papillomavirus (HPV vaccination. In spite of modern advances in diagnostic and therapeutic modalities, outcomes from cervical cancer have not markedly improved in recent years. Novel clinical trials are urgently needed to improve outcomes from cervical cancer worldwide. Methods: The Cervix Cancer Research Network (CCRN, a subsidiary of the Gynecologic Cancer InterGroup (GCIG, is a multi-national, multi-institutional consortium of physicians and scientists focused on improving cervical cancer outcomes worldwide by making cancer clinical trials available in low-, middle-, and high-income countries. Standard operating procedures for participation in CCRN include a pre-qualifying questionnaire to evaluate clinical activities and research infrastructure, followed by a site visit. Once a site is approved, they may choose to participate in one of four currently accruing clinical trials.Results: To date, 13 different CCRN site visits have been performed. Of these 13 sites visited, 10 have been approved as CCRN sites including Tata Memorial Hospital, India; Bangalore, India; Trivandrum, India; Ramathibodi, Thailand; Siriaj, Thailand; Pramongkutklao, Thailand; Ho Chi Minh, Vietnam; Blokhin Russian Cancer Research Center; the Hertzen Moscow Cancer Research Institute; and the Russian Scientific Center of Roentgenoradiology. The four currently accruing clinical trials are TACO, OUTBACK, INTERLACE, and SHAPE.Discussion: The CCRN has successfully enrolled 10 sites in developing countries to participate in four randomized clinical trials. The primary objectives are to provide novel therapeutics to regions with the greatest need and to improve the validity and generalizability of clinical trial results by enrolling a diverse sample of patients.

  8. California Breast Cancer Prevention Initiatives: Setting a research agenda for prevention. (United States)

    Sutton, P; Kavanaugh-Lynch, M H E; Plumb, M; Yen, I H; Sarantis, H; Thomsen, C L; Campleman, S; Galpern, E; Dickenson, C; Woodruff, T J


    The environment is an underutilized pathway to breast cancer prevention. Current research approaches and funding streams related to breast cancer and the environment are unequal to the task at hand. We undertook the California Breast Cancer Prevention Initiatives, a four-year comprehensive effort to set a research agenda related to breast cancer, the environment, disparities and prevention. We identified 20 topics for Concept Proposals reflecting a life-course approach and the complex etiology of breast cancer; considering the environment as chemical, physical and socially constructed exposures that are experienced concurrently: at home, in the community and at work; and addressing how we should be modifying the world around us to promote a less carcinogenic environment. Redirecting breast cancer research toward prevention-oriented discovery could significantly reduce the incidence and associated disparities of the disease among future generations.

  10. Cancer Patient and Survivor Research from the Cancer Information Service Research Consortium: A Preview of Three Large Randomized Trials and Initial Lessons Learned (United States)



    Three large randomized trials are described from the Cancer Information Service Research Consortium (CISRC). Three web-based multimedia programs are being tested to help newly diagnosed prostate (Project 1) and breast cancer patients (Project 2) make informed treatment decisions and breast cancer patients prepare for life after treatment (Project 3). Project 3 is also testing a telephone callback intervention delivered by a cancer information specialist. All participants receive standard print material specific to each project. Preliminary results from the two-month follow-up interviews are reported for the initial wave of enrolled participants, most of whom were recruited from the Cancer Information Service (1-800-4-CANCER) telephone information program (Project 1 = 208, Project 2 = 340, Project 3 = 792). Self-reported use of the multimedia program was 51%, 52% and 67% for Projects 1–3, respectively. Self-reported use of the print materials (read all, most or some) was 90%, 85% and 83% for Projects 1–3, respectively. The callback intervention was completed by 92% of Project 3 participants. Among those using the CISRC interventions, perceived utility and benefit was high, and more than 90% would recommend them to other cancer patients. Five initial lessons learned are presented that may help inform future cancer communications research. PMID:23448232

    Tovar-Guzmán Víctor


    Full Text Available INTRODUCTION: In Mexico, breast cancer (BC is one of the main causes of cancer deaths in women, with increasing incidence and mortality in recent years. Therefore, the aim of the study is identify possible risk factors related to BC. METHODS: An epidemiological study of hospital cases of BC and controls with cervical uterine cancer (CUCA was carried out at eight third level concentration hospitals in Mexico City. The total of 353 incident cases of BC and 630 controls with CUCA were identified among women younger than 75 years who had been residents of the metropolitan area of Mexico City for at least one year. Diagnosis was confirmed histologically in both groups. Variables were analyzed according to biological and statistical plausibility criteria. Univariate, bivariate and multivariate analyses were carried out. Cases and controls were stratified according to the menopausal hormonal status (pre and post menopause. RESULTS: The factors associated with BC were: higher socioeconomic level (OR= 2.77; 95%CI = 1.77 - 4.35; early menarche (OR= 1.32; 95%CI= 0.88 - 2.00; old age at first pregnancy (>31 years: OR= 5.49; 95%CI= 2.16 - 13.98 and a family history of BC (OR= 4.76; 95% CI= 2.10 - 10.79. In contrast, an increase in the duration of the breastfeeding period was a protective factor (>25 months: OR= 0.38; 95%CI= 0.20 - 0.70. CONCLUSIONS: This study contributes to the identification of risk factors for BC described in the international literature, in the population of Mexican women. Breastfeeding appears to play an important role in protecting women from BC. Because of changes in women`s lifestyles, lactation is decreasing in Mexico, and young women tend not to breastfeed or to shorten the duration of lactation.

  17. Moving forward in colorectal cancer research, what proteomics has to tell

    Institute of Scientific and Technical Information of China (English)


    Colorectal cancer is the third most common cancer and is highly fatal. During the last several years, research has been primarily based on the study of expression profiles using microarray technology. But now, investigators are putting into practice proteomic analyses of cancer tissues and cells to identify new diagnostic or therapeutic biomarkers for this cancer. Because the proteome reflects the state of a cell, tissue or organism more accurately, much is expected from proteomics to yield better tumor markers for disease diagnosis and therapy monitoring. This review summarizes the most relevant applications of proteomics the biomarker discovery for colorectal cancer.

  18. Acupoints Stimulation for Anxiety and Depression in Cancer Patients: A Quantitative Synthesis of Randomized Controlled Trials. (United States)

    Wang, Tao; Deng, Renli; Tan, Jing-Yu; Guan, Feng-Guang


    This study aims at concluding the current evidence on the therapeutic effects of acupoints stimulation for cancer patients with anxiety and depression. Randomized controlled trials using acupoints stimulation for relieving anxiety and/or depression in cancer patients were searched, and 11 studies were finally included, of which eight trials compared acupoints stimulation with standard methods of treatment/care, and acupoints stimulation showed significantly better effects in improving depression than using standard methods of treatment/care. Four studies compared true acupoints stimulation with sham methods, and no significant differences can be found between groups for either depression or anxiety, although the pooled effects still favored true intervention. For the five studies that evaluated sleep quality, the results were conflicting, with three supporting the superiority of acupoints stimulation in improving sleep quality and two demonstrating no differences across groups. Acupoints stimulation seems to be an effective approach in relieving depression and anxiety in cancer patients, and placebo effects may partially contribute to the benefits. However, the evidence is not conclusive due to the limited number of included studies and the clinical heterogeneity identified among trials. More rigorous designed randomized, sham-controlled studies are necessary in future research.

  3. A cloud-based data network approach for translational cancer research. (United States)

    Xing, Wei; Tsoumakos, Dimitrios; Ghanem, Moustafa


    We develop a new model and associated technology for constructing and managing self-organizing data to support translational cancer research studies. We employ a semantic content network approach to address the challenges of managing cancer research data. Such data is heterogeneous, large, decentralized, growing and continually being updated. Moreover, the data originates from different information sources that may be partially overlapping, creating redundancies as well as contradictions and inconsistencies. Building on the advantages of elasticity of cloud computing, we deploy the cancer data networks on top of the CELAR Cloud platform to enable more effective processing and analysis of Big cancer data.

  4. Conference Report: Eighth Annual AACR International Conference on Frontiers in Cancer Prevention Research. (United States)

    Brewster, Abenaa M; Patterson, Sherri L; Forman, Michele R; Hughes-Halbert, Chanita; Limburg, Paul J; Ondrey, Frank G; Paskett, Electra D; Wetter, David W; Hawk, Ernest T


    The Eighth Annual Frontiers in Cancer Prevention Research meeting was held in Houston, Texas, in November 2009. This report highlights significant presentations that advance the fields of chemoprevention, clinical trial recruitment and retention, cancer screening including optical imaging, energy balance, and nutritional epidemiology, and health communications and decision making. In findings from the randomized Reduction by Dutasteride of Prostate Cancer Events trial, dutasteride reduced the risk of biopsy-detectable prostate cancer in high-risk men by 23% compared with placebo. Important clues about the dosing and window of susceptibility for supplementation with choline, vitamin D, and folate were revealed from epigenetic research that has implications for future nutritional epidemiology research. Noninvasive optical imaging techniques using endoscopic ultrasound and autofluorescence for the early detection of cancers in the lung, pancreas, and oral cavity are being studied. The report also addresses the challenges of promoting cancer prevention. Understanding how individuals process risk information and make sustained behavior changes and the effect of socioeconomic status on health disparities were identified as critical areas of research. This multidisciplinary research meeting of basic, clinical, and behavioral scientists and epidemiologists continues to play a major role in identifying the research priority areas of cancer prevention, elucidating new mechanisms of carcinogenesis for targeted chemoprevention therapies and delivering a comprehensive strategy for engaging individuals in the unifying goal to reduce cancer incidence.

  5. Automatic control study of the icing research tunnel refrigeration system (United States)

    Kieffer, Arthur W.; Soeder, Ronald H.


    The Icing Research Tunnel (IRT) at the NASA Lewis Research Center is a subsonic, closed-return atmospheric tunnel. The tunnel includes a heat exchanger and a refrigeration plant to achieve the desired air temperature and a spray system to generate the type of icing conditions that would be encountered by aircraft. At the present time, the tunnel air temperature is controlled by manual adjustment of freon refrigerant flow control valves. An upgrade of this facility calls for these control valves to be adjusted by an automatic controller. The digital computer simulation of the IRT refrigeration plant and the automatic controller that was used in the simulation are discussed.

  6. An Optimal Control of Bone Marrow in Cancer Chemotherapy by Artificial Neural Networks

    Directory of Open Access Journals (Sweden)

    H. Hosseinipour


    Full Text Available Although neural network models for cancer chemotherapy have been analyzed since the early seventies, less research has been done in actually formulating them as optimal control problems. In this paper an artificial neural networks-based method for optimal control of bone marrow in cell-cycle-specific chemotherapy is proposed. In this method, we use artificial neural networks for approximating the optimal control problem which maximizes both bone marrow mass and drug`s dose at the same time. The corresponding model be transfer to Hamiltonian function and using Pontryagin principle we create the boundary conditions. After defining boundary conditions, we use the approximating property of artificial networks and put the boundary conditions in error functions to satisfy the limitations..

  7. A breast cancer clinical registry in an Italian comprehensive cancer center: an instrument for descriptive, clinical, and experimental research. (United States)

    Baili, Paolo; Torresani, Michele; Agresti, Roberto; Rosito, Giuseppe; Daidone, Maria Grazia; Veneroni, Silvia; Cavallo, Ilaria; Funaro, Francesco; Giunco, Marco; Turco, Alberto; Amash, Hade; Scavo, Antonio; Minicozzi, Pamela; Bella, Francesca; Meneghini, Elisabetta; Sant, Milena


    In clinical research, many potentially useful variables are available via the routine activity of cancer center-based clinical registries (CCCR). We present the experience of the breast cancer clinical registry at Fondazione IRCCS "Istituto Nazionale dei Tumori" to give an example of how a CCCR can be planned, implemented, and used. Five criteria were taken into consideration while planning our CCCR: (a) available clinical and administrative databases ought to be exploited to the maximum extent; (b) open source software should be used; (c) a Web-based interface must be designed; (d) CCCR data must be compatible with population-based cancer registry data; (e) CCCR must be an open system, able to be connected with other data repositories. The amount of work needed for the implementation of a CCCR is inversely linked with the amount of available coded data: the fewer data are available in the input databases as coded variables, the more work will be necessary, for information technology staff, text mining analysis, and registrars (for collecting data from clinical records). A cancer registry in a comprehensive cancer center can be used for several research aspects, such as estimate of the number of cases needed for clinical studies, assessment of biobank specimens with specific characteristics, evaluation of clinical practice and adhesion to clinical guidelines, comparative studies between clinical and population sets of patients, studies on cancer prognosis, and studies on cancer survivorship.

  8. Cancer Research Center Indiana University School of Medicine

    Energy Technology Data Exchange (ETDEWEB)


    The Department of Energy (DOE) proposes to authorize the Indiana School of Medicine to proceed with the detailed design, construction and equipping of the proposed Cancer Research Center (CRC). A grant was executed with the University on April 21, 1992. A four-story building with basement would be constructed on the proposed site over a 24-month period. The proposed project would bring together, in one building, three existing hematology/oncology basic research programs, with improved cost-effectiveness through the sharing of common resources. The proposed site is currently covered with asphaltic pavement and is used as a campus parking lot. The surrounding area is developed campus, characterized by buildings, walkways, with minimal lawns and plantings. The proposed site has no history of prior structures and no evidence of potential sources of prior contamination of the soil. Environmental impacts of construction would be limited to minor increases in traffic, and the typical noises associated with standard building construction. The proposed CRC project operation would involve the use radionuclides and various hazardous materials in conducting clinical studies. Storage, removal and disposal of hazardous wastes would be managed under existing University programs that comply with federal and state requirements. Radiological safety programs would be governed by Nuclear Regulatory Commission (NRC) license and applicable Environmental Protection Agency (EPA) regulations. There are no other NEPA reviews currently active which are in relationship to this proposed site. The proposed project is part of a Medical Campus master plan and is consistent with applicable local zoning and land use requirements.

  9. Dr. Josef Steiner Cancer Research Prize Lecture: the role of physiological cell death in neoplastic transformation and in anti-cancer therapy. (United States)

    Strasser, A


    Cell death is a physiological process which is required for normal development and existence of multi-cellular organisms. Physiological cell death, or apoptosis, is controlled by an evolutionarily conserved mechanism. Abnormalities in this process are implicated as a cause or contributing factor in a variety of diseases. Inhibition of apoptosis can promote neoplastic transformation, particularly in combination with dysregulated cell-cycle control, and can influence the response of tumour cells to anti-cancer therapy. Molecular biological and biochemical approaches are used to find missing cell-death regulators and to define signalling cascades, while experiments in genetically modified mice will identify the essential function of these molecules. Discoveries from cell death research should provide clues for designing therapies for a variety of diseases, including degenerative disorders, auto-immunity and cancer.

  11. Research methods to change clinical practice for patients with rare cancers. (United States)

    Billingham, Lucinda; Malottki, Kinga; Steven, Neil


    Rare cancers are a growing group as a result of reclassification of common cancers by molecular markers. There is therefore an increasing need to identify methods to assess interventions that are sufficiently robust to potentially affect clinical practice in this setting. Methods advocated for clinical trials in rare diseases are not necessarily applicable in rare cancers. This Series paper describes research methods that are relevant for rare cancers in relation to the range of incidence levels. Strategies that maximise recruitment, minimise sample size, or maximise the usefulness of the evidence could enable the application of conventional clinical trial design to rare cancer populations. Alternative designs that address specific challenges for rare cancers with the aim of potentially changing clinical practice include Bayesian designs, uncontrolled n-of-1 trials, and umbrella and basket trials. Pragmatic solutions must be sought to enable some level of evidence-based health care for patients with rare cancers.

  12. Astronomy and Cancer Research: X-Rays and Nanotechnology from Black Holes to Cancer Therapy (United States)

    Pradhan, Anil K.; Nahar, Sultana N.

    It seems highly unlikely that any connection is to be found between astronomy and medicine. But then it also appears to be obvious: X-rays. However, that is quite superficial because the nature of X-rays in the two disciplines is quite different. Nevertheless, we describe recent research on exactly that kind of link. Furthermore, the linkage lies in atomic physics, and via spectroscopy which is a vital tool in astronomy and may also be equally valuable in biomedical research. This review begins with the physics of black hole environments as viewed through X-ray spectroscopy. It is then shown that similar physics can be applied to spectroscopic imaging and therapeutics using heavy-element (high-Z) moieties designed to target cancerous tumors. X-ray irradiation of high-Z nanomaterials as radiosensitizing agents should be extremely efficient for therapy and diagnostics (theranostics). However, broadband radiation from conventional X-ray sources (such as CT scanners) results in vast and unnecessary radiation exposure. Monochromatic X-ray sources are expected to be considerably more efficient. We have developed a new and comprehensive methodology—Resonant Nano-Plasma Theranostics (RNPT)—that encompasses the use of monochromatic X-ray sources and high-Z nanoparticles. Ongoing research entails theoretical computations, numerical simulations, and in vitro and in vivo biomedical experiments. Stemming from basic theoretical studies of Kα resonant photoabsorption and fluorescence in all elements of the Periodic Table, we have established a comprehensive multi-disciplinary program involving researchers from physics, chemistry, astronomy, pathology, radiation oncology and radiology. Large-scale calculations necessary for theory and modeling are done at a variety of computational platforms at the Ohio Supercomputer Center. The final goal is the implementation of RNPT for clinical applications.

  13. Breast Cancer in Young Women: Research Priorities. A Report of the Young Survival Coalition Research Think Tank Meeting. (United States)

    Korde, Larissa A; Partridge, Ann H; Esser, Michelle; Lewis, Stacy; Simha, Joy; Johnson, Rebecca H


    Breast cancer in young women is a significant issue-7% of all female breast cancer is diagnosed in women under 40 years of age. Young women with breast cancer (YWBC) face significant and unique challenges, including a higher likelihood of biologically aggressive disease and metastatic disease at diagnosis, leading to poorer prognosis, more aggressive treatment and long-term treatment-related toxicities, and unique psychosocial concerns. This article summarizes the Young Survival Coalition (YSC) Research Think Tank Meeting, held in Arlington, Virginia, in February 2013, and presents the process that led to YSC's priorities for YWBC research. The meeting's participants focused on six broad categories of investigation in which additional advancements in research on YWBC are crucial: risk factors; treatment; fertility; pregnancy-associated breast cancer; quality of life and survivorship; and metastasis. Several key themes emerged from this meeting. Researchers and advocates felt that a large-scale data registry focused on YWBC is necessary to collect quality information to guide future research for YWBC. This database should include clinical data, genomic profiling of primary tumor and metastatic sites, and an increased focus on fertility and pregnancy following breast cancer treatment. The participants also felt that more must be done to elucidate how and why YWBC develop more aggressive tumors, and to what degree treatment should be modified for young women. The discussions summarized here led to the formulation of YSC's Research Agenda, published in May 2014.

  14. Family history of cancer and the risk of laryngeal cancer: a case-control study from Italy and Switzerland. (United States)

    Garavello, Werner; Turati, Federica; Bosetti, Cristina; Talamini, Renato; Levi, Fabio; Lucenteforte, Ersilia; Chiesa, Fausto; Franceschi, Silvia; La Vecchia, Carlo; Negri, Eva


    Only limited data is available on the relationship between family history of laryngeal and other neoplasms and laryngeal cancer risk. We investigated the issue using data from a multicentre case-control study conducted in Italy and Switzerland between 1992 and 2009 including 852 cases with histologically confirmed laryngeal cancer and 1970 controls admitted to hospital for acute, non neoplastic conditions. Unconditional logistic regression models adjusted for age, sex, study center, education, tobacco smoking, alcohol drinking and number of siblings were used to estimate the odds ratios (ORs) of laryngeal cancer. The multivariate OR was 2.8 (95% confidence interval [CI], 1.5-5.3) in subjects reporting a first-degree relative with laryngeal cancer, as compared to subjects with no family history. The OR was higher when the relative was diagnosed before 60 years of age (OR = 3.5, 95% CI 1.4-8.8). As compared to subjects without family history, non-smokers, and moderate drinkers, the OR was 37.1 (95% CI 9.9-139.4) for current smokers, heavy drinkers, with family history of laryngeal cancer. Family history of colorectal (OR = 1.5, 95% CI 1.0-2.3) and kidney (OR = 3.8, 95% CI 1.2-12.1) cancer were also associated to an increased risk of laryngeal cancer, while no significant increase in risk was found for family history of cancer at all sites, excluding the larynx (OR = 1.1).

    To identify research priorities and appropriate resources and to establish the infrastructure required to address the emergency care of patients with cancer, the National Institutes of Health's National Cancer Institute and the Office of Emergency Care Research sponsored a one-day workshop, "Cancer and Emergency Medicine: Setting the Research Agenda," in March 2015 in Bethesda, MD. Participants included leading researchers and clinicians in the fields of oncology, emergency medicine, and palliative care, and representatives from the National Institutes of Health. Attendees were charged with identifying research opportunities and priorities to advance the understanding of the emergency care of cancer patients. Recommendations were made in 4 areas: the collection of epidemiologic data, care of the patient with febrile neutropenia, acute events such as dyspnea, and palliative care in the emergency department setting.

  16. Size-controlled synthesis of biodegradable nanocarriers for targeted and controlled cancer drug delivery using salting out cation

    Indian Academy of Sciences (India)

    Madasamy Hari Balakrishanan; Mariappan Rajan


    Research for synthesis of size-controlled carriers is currently challenging one. In this research paper, a method for size-controlled synthesis of biodegradable nanocarriers is proposed and described. Salting out method is suitable for both hydrophilic and hydrophobic drugs for the encapsulation on carriers. This synthetic method is based on polylactic acid (PLA) and non-ionic carboxymethyl cellulose (CMC) composed by CaCl2 as salting out agent. This method permits size-controlled synthesis of particles between 50 and 400 nm simply by varying the concentration of salting out agents. We have prepared cisplatin (CDDP)-loaded PLA-CMC nanocarriers by salting out method, with varying salting out agent (CaCl2) concentrations as 0.05, 0.2, 0.35 and 0.5 M. The nanocarriers were characterized for their size, surface charge and morphology by atomic force microscope, zeta potential analyser and transmission electron microscope, respectively. The encapsulation efficiency and in-vitro drug-releasing behaviour of the nanocarriers were investigated. The cytotoxicity effect of nanocarriers and drug-loaded nanocarriers was tested against MCF-7 breast cancer cell line.

    Babak Saedi


    Full Text Available Introduction: As one of the most common cancers among head and neck malignancies, cancer of the oral cavity probably has some variations in countries with a high prevalence of esophageal cancer.  Materials and Methods: Patients with oral cavity cancer who were treated at two tertiary referral centers from January 1999 to January 2009 were included in this study. In addition to demographic data, information regarding personal and family history of head and neck cancer, use of dentures, presence of immune deficiency, consumption of alcohol, and incidence of cigarette smoking was collected. Additionally, a history of opium usage was obtained from the participants in this study. Moreover, an appropriately matched control group was selected for comparisons between the risk factors.   Results: A total of 557 patients were entered into this study over a 10-year period, of whom 219 (39.3% were female and the remaining 338 (60.7% were male. The tongue was the most common site of cancer and 9% of the patients had a history of opium abuse, but more than half of the patients did not have any recognized risk factors. The incidence and stage of cancer had a significant relationship with cigarette smoking (P= 0.013.   Conclusion: Tongue cancer in non-smokers is the predominant pattern of oral cavity cancer in Iran.

  1. A Cross-Cultural Perspective on Challenges Facing Comparative Cancer Survivorship Research

    Directory of Open Access Journals (Sweden)

    Astri Syse


    Full Text Available Cancer survivorship research includes the study of physical, psychosocial, and economic consequences of cancer diagnosis and treatment among pediatric and adult cancer survivors. Historically, the majority of cancer survivorship studies were from the United States, but survivorship issues are increasingly being addressed in other developed countries. Cross-cultural studies remain, however, scarce. The degree to which knowledge attained may or may not be transferred across cultures, countries, or regions is not known. Some important challenges for comparative research are therefore discussed in a cross-cultural perspective. Several substantive and methodological challenges that complicate the execution of cross-cultural cancer survivorship research are presented with examples and discussed to facilitate comparative research efforts in the establishment of new survivorship cohorts and in the planning and implementation of survivorship studies. Comparative research is one key to understanding the nature of cancer survivorship, distinguishing modifiable from nonmodifiable factors at individual, hospital, societal, and system levels and may thus guide appropriate interventions. Lastly, suggested future courses of action within the field of comparative cancer survivorship research are provided.

  2. [Cancer treatment in elderly patients: evidence and clinical research]. (United States)

    Repetto, Lazzaro; Luciani, Andrea


    showed a good sensibility (87.3%) but a low specificity (62%) with respect to CGA for the diagnosis of patients with disabilities. Overcash et al. proposed an abbreviated form of CGA using a reduced number of items of ADL, IADL, MMSE and GDS. There was a good correlation between complete and reduced scales (coefficient of correlation 0.8). G8 is a screening tool composed of 8 questions that explore functional, cognitive and nutritional status. The score with the best equilibrium between sensibility and specificity was 14 (sensibility 85% and specificity 65%). In the first observational trial age, hystotype, chemotherapy dose, haemoglobin (man: 11 g/dL; women: 10 g/dL), creatinine clearance less than 34 mL/min (Jelliffe formula), earing problems, at least a fall in the last six months, walking problems, low social activity, were related to a major risk of toxicity; in another trial IADL, diastolic blood pressure, LDH and MAX2 index were predictive of haematological toxicity, while performance status, Mini-Mental Status score, Mini-Nutritional Assessment (MNA) score and MAX2 index were predictive of non haematological toxicity. Based on these parameters a 0-2 score was developed. A recent "position article" of EORTC (European organization for Research and Treatment of Cancer) and SIOG analyzed the pro and the contra of the use of some indicators in elderly patients. The overall survival (OS) frequently used in classical clinical trial could give wrong messages as there are some competitive risks of death in elderly patients. Another important indicator is the disease specific survival (DSS). Concerning the design of clinical trials, a possible strategy is to enrol elderly patients without upper age limit and to plan stratification. An interesting trial design is the so called "extended trial" that allow to re-open the arm of a trial in which a too low number of older patients was enrolled.

  3. Research from the Early Detection Research Network on New Methods to Detect Prostate Cancer | Division of Cancer Prevention (United States)

    Prostate cancer is the most frequently diagnosed non-skin cancer in men in the United States. In 2010 there were 218,000 men diagnosed with prostate cancer. The prevalence of the diagnosis makes the disease a major health burden. While the majority of the diagnosed men will survive the disease, about 15% will die from it, a rate that is affected by over-diagnosis and the consequent over-treatment. |

    Pillow, P C; Hursting, S D; Duphorne, C M; Jiang, H; Honn, S E; Chang, S; Spitz, M R


    In this case-control study we determined whether dietary differences underlie some of the ethnic and sex differences in US lung cancer rates. We examined the relationship between diet and lung cancer development in 137 lung cancer cases (93 African Americans and 44 Mexican Americans) and 187 controls (78 African Americans and 109 Mexican Americans). Cases reported a higher daily mean total fat intake (p fruits (p = 0.02). Ethnic differences in diet were also observed: Mexican Americans consumed less total fat (p fruits (p lung cancer risk (p fruit consumption and lung cancer risk (p = 0.05). In conclusion, our findings support the hypothesis that diet, particularly high fat consumption and low fruit and vegetable consumption, contributes (independent of cigarette smoking) to the excess lung cancer risk in African-American men, who have the highest lung cancer rates in the United States.

    Rustagi, Alison S; Kamineni, Aruna; Weinmann, Sheila; Reed, Susan D; Newcomb, Polly; Weiss, Noel S


    Recent research suggests that cervical screening of older women is associated with a considerable decrease in cervical cancer incidence. We sought to quantify the efficacy of cervical cytology screening to reduce death from this disease. Among enrollees of 2 US health plans, we compared Papanicolaou smear screening histories of women aged 55-79 years who died of cervical cancer during 1980-2010 (cases) to those of women at risk of cervical cancer (controls). Controls were matched 2:1 to cases on health plan, age, and enrollment duration. Cytology screening during the detectable preclinical phase, estimated as the 5-7 years before diagnosis during which cervical neoplasia is asymptomatic but cytologically detectable, was ascertained from medical records. A total of 39 cases and 80 controls were eligible. The odds ratio of cervical cancer death associated with screening during the presumed detectable preclinical phase was 0.26 (95% confidence interval: 0.10, 0.63) after adjustment for matching characteristics, smoking, marital status, and race/ethnicity using logistic regression. We estimate that cervical cytology screening of all women aged 55-79 years in the United States could avert 630 deaths annually. These results provide a minimum estimate of the efficacy of human papillomavirus DNA screening-a more sensitive test-to reduce cervical cancer death among older women.

  9. Leininger's Ethnonursing Research Methodology and Studies of Cancer Survivors: A Review. (United States)

    Farren, Arlene T


    The purpose of this article is to present the findings of a literature review regarding the use of Leininger's ethnonursing research methodology (ENRM) in studies addressing adult cancer survivors. It is important to learn about differences and similarities among cancer survivors' experiences so that patient-centered, culturally congruent care can be provided. A review of the literature was conducted using databases such as CINAHL and MEDLINE. Search terms included variations on ENRM and cancer survivors. The results were a small number of published studies that used the ENRM examining breast cancer survivors' perceptions and experiences. A review instrument was developed to estimate study quality based on established criteria. The studies are critiqued in relation to the theory-based methodology, evaluation criteria for qualitative research, and study findings are summarized. The author concludes that although there is a paucity of research using ENRM with adult cancer survivors, the preliminary findings of the included studies contribute to what is known about breast cancer survivors. Implications for research include recommendations to increase the use of ENRM to discover the universal and diverse experiences of care practices in adult cancer survivors and use the evidence to develop patient-centered, culturally congruent, quality care for cancer survivors.

    Wei Zhuang; Limin Lun


    Objective The aim of the study was to investigate the inhibitory ef ects of dendritic cel s (DCs) loaded with resistant breast cancer antigens on breast cancer in nude mice. Methods A single-cel suspension was prepared from a primary breast cancer and chemotherapeutic drugs were screened using the ATP-PCA susceptibility testing system. Cancer cel s were treated with 1/10 × IC50, 1/5 × IC50, 1/2 × IC50, 1 × IC50, and 2 × IC50 medium until their growth became steady in the 2 × IC50 medium. Peripheral blood mononuclear cel s (PBMCs) were obtained from the peripheral blood of patients with leukapheresis. The obtained adherent cel s were induced by granulocyte-macrophage colony-stimu-lating factor (GM-CSF) and interleukin-4 (IL-4) to generate DCs, which carried resistant strain cel lysis compounds or non-treated cancer cel lysis compounds. The former mature DCs carried resistant breast tumor antigens. A breast tumor-bearing nude mouse model was established with these resistant strains and the mice were randomly divided in three groups. The mice in the treatment group were injected with DCs loaded with resistant breast cancer antigens. The control group consisted of mice injected with DCs loaded with primary tumor cel antigens and the blank group consisted of mice injected with the same volume of normal saline. Changes in the cancers were observed. Results After treatment with the ef ector cel s, the cancer volume and weight were significantly dif erent to those before treatment in every group of mice (P Conclusion DCs loaded with resistant breast cancer antigens demonstrated a significant inhibition ef ect on the cancers of breast tumor-bearing nude mice.

  16. Caring for caregivers and patients: Research and clinical priorities for informal cancer caregiving. (United States)

    Kent, Erin E; Rowland, Julia H; Northouse, Laurel; Litzelman, Kristin; Chou, Wen-Ying Sylvia; Shelburne, Nonniekaye; Timura, Catherine; O'Mara, Ann; Huss, Karen


    Informal/family caregivers are a fundamental source of care for cancer patients in the United States, yet the population of caregivers and their tasks, psychosocial needs, and health outcomes are not well understood. Changes in the nature of cancer care and its delivery, along with the growing population of survivors and their caregivers, warrant increased attention to the roles and demands of caregiving. This article reviews current evidence presented at a 2-day meeting examining the state of the science of informal cancer caregiving that was convened by the National Cancer Institute and the National Institute of Nursing Research. The meeting sought to define who is an informal cancer caregiver, summarize the state of the science in informal cancer caregiving, and describe both the kinds of interventions developed to address caregiving challenges and the various outcomes used to evaluate their impact. This article offers recommendations for moving science forward in 4 areas: 1) improving the estimation of the prevalence and burden of informal cancer caregiving; 2) advancing the development of interventions designed to improve outcomes for cancer patients, caregivers, and patient-caregiver dyads; 3) generating and testing strategies for integrating caregivers into formal health care settings; and 4) promoting the use of technology to support informal cancer caregivers.

  17. Army/NASA small turboshaft engine digital controls research program (United States)

    Sellers, J. F.; Baez, A. N.


    The emphasis of a program to conduct digital controls research for small turboshaft engines is on engine test evaluation of advanced control logic using a flexible microprocessor based digital control system designed specifically for research on advanced control logic. Control software is stored in programmable memory. New control algorithms may be stored in a floppy disk and loaded directly into memory. This feature facilitates comparative evaluation of different advanced control modes. The central processor in the digital control is an Intel 8086 16 bit microprocessor. Control software is programmed in assembly language. Software checkout is accomplished prior to engine test by connecting the digital control to a real time hybrid computer simulation of the engine. The engine currently installed in the facility has a hydromechanical control modified to allow electrohydraulic fuel metering and VG actuation by the digital control. Simulation results are presented which show that the modern control reduces the transient rotor speed droop caused by unanticipated load changes such as cyclic pitch or wind gust transients.

    Al-Othman, Saleh; Haoudi, Abdelali; Alhomoud, Samar; Alkhenizan, Abdullah; Khoja, Tawfik; Al-Zahrani, Ali


    Cancer is a major health problem in both high income and middle-to-low income countries, and is the second leading cause of death in the world. Although more than a third of cancer could be prevented and another third could be cured if diagnosed early, it remains a huge challenge to health-care systems worldwide. Despite substantial improvements in health services some of the countries in the Gulf region, the burden of non-communicable diseases is a major threat, primarily due to the rapid socioeconomic shifts that have led to unfavourable changes in lifestyle such as increased tobacco use, decreased physical activity, and consumption of unhealthy food. In the Gulf Cooperation Council states (United Arab Emirates, Bahrain, Saudi Arabia, Oman, Qatar, and Kuwait), advanced breast cancer, colorectal cancer, leukaemia, thyroid cancer, and non-Hodgkin lymphomas are the most common cancers affecting younger populations compared with other countries. By contrast with cancer prevalence in developed countries, prostate, lung, and cervical cancers are not among the most common cancers in the Gulf region. In view of the increased cost of cancer management worldwide, integrated approaches between primary, secondary, and tertiary health-care systems with special focus on prevention and early detection is an essential step in the countries' efforts in the fight against cancer.

    Summary Background Ovarian cancer has a poor prognosis, with just 40% of patients surviving 5 years. We designed this trial to establish the effect of early detection by screening on ovarian cancer mortality. Methods In this randomised controlled trial, we recruited postmenopausal women aged 50–74 years from 13 centres in National Health Service Trusts in England, Wales, and Northern Ireland. Exclusion criteria were previous bilateral oophorectomy or ovarian malignancy, increased risk of familial ovarian cancer, and active non-ovarian malignancy. The trial management system confirmed eligibility and randomly allocated participants in blocks of 32 using computer-generated random numbers to annual multimodal screening (MMS) with serum CA125 interpreted with use of the risk of ovarian cancer algorithm, annual transvaginal ultrasound screening (USS), or no screening, in a 1:1:2 ratio. The primary outcome was death due to ovarian cancer by Dec 31, 2014, comparing MMS and USS separately with no screening, ascertained by an outcomes committee masked to randomisation group. All analyses were by modified intention to screen, excluding the small number of women we discovered after randomisation to have a bilateral oophorectomy, have ovarian cancer, or had exited the registry before recruitment. Investigators and participants were aware of screening type. This trial is registered with, number NCT00058032. Findings Between June 1, 2001, and Oct 21, 2005, we randomly allocated 202 638 women: 50 640 (25·0%) to MMS, 50 639 (25·0%) to USS, and 101 359 (50·0%) to no screening. 202 546 (>99·9%) women were eligible for analysis: 50 624 (>99·9%) women in the MMS group, 50 623 (>99·9%) in the USS group, and 101 299 (>99·9%) in the no screening group. Screening ended on Dec 31, 2011, and included 345 570 MMS and 327 775 USS annual screening episodes. At a median follow-up of 11·1 years (IQR 10·0–12·0), we diagnosed ovarian cancer in

  20. Confounding Effect in Clinical Research of Otolaryngology and Its Control. (United States)

    Yu, Yong-qiang; Huang, Dong-yan; Armijo Olivo, Susan; Yang, Huai-an; Bambanini, Yagesh; Sonnenberg, Lyn; Clark, Brenda; Constantinescu, Gabriela; Qian Yu, Jason; Zhang, Ming


    Confounding effect is a critical issue in clinical research of otolaryngology because it can distort the research's conclusion. In this review, we introduce the definition of confounding effect, the methods of verifying and controlling the effect. Confounding effect can be prevented by research's design, and adjusted by data analysis. Clinicians would be aware and cautious about confounding effect in their research. They would be able to set up a research's design in which appropriate methods have been applied to prevent this effect.They would know how to adjust confounding effect after data collection. It is important to remember that sometimes it is impossible to eliminate confounding effect completely, and statistical method is not a master key. Solid research knowledge and critical thinking of our brain are the most important in controlling confounding effect.

  1. Case-control study of arsenic in drinking water and lung cancer in California and Nevada. (United States)

    Dauphiné, David C; Smith, Allan H; Yuan, Yan; Balmes, John R; Bates, Michael N; Steinmaus, Craig


    Millions of people are exposed to arsenic in drinking water, which at high concentrations is known to cause lung cancer in humans. At lower concentrations, the risks are unknown. We enrolled 196 lung cancer cases and 359 controls matched on age and gender from western Nevada and Kings County, California in 2002-2005. After adjusting for age, sex, education, smoking and occupational exposures, odds ratios for arsenic concentrations ≥85 µg/L (median = 110 µg/L, mean = 173 µg/L, maximum = 1,460 µg/L) more than 40 years before enrollment were 1.39 (95% CI = 0.55-3.53) in all subjects and 1.61 (95% CI = 0.59-4.38) in smokers. Although odds ratios were greater than 1.0, these increases may have been due to chance given the small number of subjects exposed more than 40 years before enrollment. This study, designed before research in Chile suggested arsenic-related cancer latencies of 40 years or more, illustrates the enormous sample sizes needed to identify arsenic-related health effects in low-exposure countries with mobile populations like the U.S. Nonetheless, our findings suggest that concentrations near 100 µg/L are not associated with markedly high relative risks.

    Wu, Gang; Wu, Deng-long


    Prostate cancer is one of the most common malignancies threatening men's health, and the mechanisms underlying its initiation and progression are poorly understood. Last decade has witnessed encouraging progress in the studies of prostate cancer stem cells (PCSCs), which are considered to play important roles in tumor initiation, recurrence and metastasis, castration resistance, and drug resistance. Therefore, a deeper insight into PCSCs is of great significance for the successful management of prostate cancer. This article presents an overview on the location, origin, and markers of PCSCs as well as their potential correlation with tumor metastasis and castration resistance.

  6. The facilities and challenges for cancer control in India. (United States)

    Desai, P B


    India is a vast subcontinent with 845 million peoples occupying 2.5% of land mass of the earth, but carrying 15% of the world population. It is a multiracial society with widely varying cultures, habits, languages and many different ethnic groups. The pattern of cancer, therefore, mainly depends on their habits and life styles apart from other variations. Head, Neck & Esophagus cancers in the male and cervix and breast cancers in the females are the main cancers. All together they form nearly 60% of all cancers. The incidence rates are around 90/100,000 though this is an underestimate as cancer is not a notifiable disease in India. It is estimated that by the year 2,000 there will be six million cancer patients in India at any given time with nearly 2 million new patients annually. The over-all facilities for cancer treatment vary widely from metropolitan cities to rural areas where 70% of the Indian population lives. In major cities, good to excellent treatment facilities exist in comprehensive cancer centres--yet in the rural setting the facilities are sketchy at best or non-existent at worst. The Government of India in its national cancer policy has recognized regional cancer centres and consolidated other existing centres. There are 10 regional cancer centres thus identified, each one at a different level of development. For optimal requirements at least 600 teletherapy units, (existing 150--not always functional) 100 departments of surgical oncology and an equal number of medical oncology divisions are needed (existing 20). The demand for cancer treatment facilities are, therefore, very high with poor available facility. Nearly 50% of patients present late for treatment and therefore appropriate education in prevention and early diagnosis are important factors. The Government of India through Ministry of Health has identified cancer as a major health problem by the year 2,000 and hence planning by the National Cancer Plan is operative in many States. Major

  11. Fifty years of tobacco carcinogenesis research: from mechanisms to early detection and prevention of lung cancer. (United States)

    Hecht, Stephen S; Szabo, Eva


    The recognition of the link between cigarette smoking and lung cancer in the 1964 Surgeon General's Report initiated definitive and comprehensive research on the identification of carcinogens in tobacco products and the relevant mechanisms of carcinogenesis. The resultant comprehensive data clearly illustrate established pathways of cancer induction involving carcinogen exposure, metabolic activation, DNA adduct formation, and consequent mutation of critical genes along with the exacerbating influences of inflammation, cocarcinogenesis, and tumor promotion. This mechanistic understanding has provided a framework for the regulation of tobacco products and for the development of relevant tobacco carcinogen and toxicant biomarkers that can be applied in cancer prevention. Simultaneously, the recognition of the link between smoking and lung cancer paved the way for two additional critical approaches to cancer prevention that are discussed here: detection of lung cancer at an early, curable stage, and chemoprevention of lung cancer. Recent successes in more precisely identifying at-risk populations and in decreasing lung cancer mortality with helical computed tomography screening are notable, and progress in chemoprevention continues, although challenges with respect to bringing these approaches to the general population exist. Collectively, research performed since the 1964 Report demonstrates unequivocally that the majority of deaths from lung cancer are preventable.

  12. Use of disulfiram and risk of cancer: a population-based case-control study. (United States)

    Askgaard, Gro; Friis, Søren; Hallas, Jesper; Thygesen, Lau C; Pottegård, Anton


    Experimental studies have indicated that disulfiram (Antabuse) has antineoplastic effects against melanoma, breast, and prostate cancer. To explore this hypothesis, we examined the association between disulfiram use and these cancers in a nationwide register-based case-control study nested within ever-users (≥one prescription) of disulfiram. Cases were all Danish individuals with a histologically verified first-time diagnosis of malignant melanoma, breast, or prostate cancer during 2000-2009. For each case, we selected four cancer-free controls matched for age, sex, and year of first disulfiram prescription using risk set sampling. Similarly, for secondary analyses, we selected case-control populations for selected tobacco-related and alcohol-related cancer types, that is, cancers of the buccal cavity, liver, lung, and colorectal cancer. Disulfiram use 1 year before cancer diagnosis and the corresponding date for controls were disregarded. We estimated crude and adjusted odds ratios and 95% confidence intervals (CI) for cancer associated with long-term (≥500 daily defined doses) versus one-time (one prescription) use of disulfiram. Among 53 856 disulfiram users, we identified 166, 644, and 464 cases, respectively, of melanoma, breast, or prostate cancer. Adjusted odds ratios for melanoma, breast, or prostate cancer associated with long-term disulfiram use were 1.04 (95% CI: 0.60-1.78), 0.92 (95% CI: 0.70-1.22), and 0.77 (95% CI: 0.56-1.06), respectively. For prostate cancer, dose-response analyses showed a further risk reduction with the highest cumulative dose level of disulfiram; however, the test for trend did not reach statistical significance. Our study provides some epidemiological support for a protective effect of disulfiram against prostate and breast cancer.

  14. Pancreatic cancer: Translational research aspects and clinical implications

    Institute of Scientific and Technical Information of China (English)

    Daniel Ansari; Bi-Cheng Chen; Lei Dong; Meng-Tao Zhou; Roland Andersson


    Despite improvements in surgical techniques and adjuvant chemotherapy,the overall mortality rates in pancreatic cancer have generally remained relatively unchanged and the 5-year survival rate is actually below 2%.This paper will address the importance of achieving an early diagnosis and identifying markers for prognosis and response to therapy such as genes,proteins,microRNAs or epigenetic modifications.However,there are still major hurdles when translating investigational biomarkers into routine clinical practice.Furthermore,novel ways of secondary screening in high-risk individuals,such as artificial neural networks and modern imaging,will be discussed.Drug resistance is ubiquitous in pancreatic cancer.Several mechanisms of drug resistance have already been revealed,including human equilibrative nucleoside transporter-1 status,multidrug resistance proteins,aberrant signaling pathways,microRNAs,stromal influence,epithelial-mesenchymal transition-type cells and recently the presence of cancer stem cells/cancer-initiating cells.These factors must be considered when developing more customized types of intervention ("personalized medicine").In the future,multifunctional nanoparticles that combine a specific targeting agent,an imaging probe,a cell-penetrating agent,a biocompatible polymer and an anti-cancer drug may become valuable for the management of patients with pancreatic cancer.

  15. Control of Apoptosis in Treatment and Biology of Pancreatic Cancer. (United States)

    Modi, Shrey; Kir, Devika; Banerjee, Sulagna; Saluja, Ashok


    Pancreatic cancer is estimated to be the 12th most common cancer in the United States in 2014 and yet this malignancy is the fourth leading cause of cancer-related death in the United States. Late detection and resistance to therapy are the major causes for its dismal prognosis. Apoptosis is an actively orchestrated cell death mechanism that serves to maintain tissue homoeostasis. Cancer develops from normal cells by accruing significant changes through one or more mechanisms, leading to DNA damage and mutations, which in a normal cell would induce this programmed cell death pathway. As a result, evasion of apoptosis is one of the hallmarks of cancer cells. PDAC is notoriously resistant to apoptosis, thereby explaining its aggressive nature and resistance to conventional treatment modalities. The current review is focus on understanding different intrinsic and extrinsic pathways in pancreatic cancer that may affect apoptosis in this disease.

RESULTS:: Twelve patients (6 male and 6 female patients; mean age, 72.4 years) participated in the study. The analyses show that the patients physically experienced readiness to leave...

  17. Three interrelated themes in current breast cancer research: gene addiction, phenotypic plasticity, and cancer stem cells. (United States)

    Cardiff, Robert D; Couto, Suzana; Bolon, Brad


    Recent efforts to understand breast cancer biology involve three interrelated themes that are founded on a combination of clinical and experimental observations. The central concept is gene addiction. The clinical dilemma is the escape from gene addiction, which is mediated, in part, by phenotypic plasticity as exemplified by epithelial-to-mesenchymal transition and mesenchymal-to-epithelial transition. Finally, cancer stem cells are now recognized as the basis for minimal residual disease and malignant progression over time. These themes cooperate in breast cancer, as induction of epithelial-to-mesenchymal transition enhances self-renewal and expression of cancer stem cells, which are believed to facilitate tumor resistance.

    Zernicke Kristin A


    Full Text Available Abstract Background Elevated stress can exacerbate cancer symptom severity, and after completion of primary cancer treatments, many individuals continue to have significant distress. Mindfulness-Based Cancer Recovery (MBCR is an 8-week group psychosocial intervention consisting of training in mindfulness meditation and yoga designed to mitigate stress, pain, and chronic illness. Efficacy research shows face-to-face (F2F MBCR programs have positive benefits for cancer patients; however barriers exist that impede participation in F2F groups. While online MBCR groups are available to the public, none have been evaluated. Primary objective: determine whether underserved patients are willing to participate in and complete an online MBCR program. Secondary objectives: determine whether online MBCR will mirror previous efficacy findings from F2F MBCR groups on patient-reported outcomes. Method/design The study includes cancer patients in Alberta, exhibiting moderate distress, who do not have access to F2F MBCR. Participants will be randomized to either online MBCR, or waiting for the next available group. An anticipated sample size of 64 participants will complete measures online pre and post treatment or waiting period. Feasibility will be tracked through monitoring numbers eligible and participating through each stage of the protocol. Discussion 47 have completed/completing the intervention. Data suggest it is possible to conduct a randomized waitlist controlled trial of online MBCR to reach underserved cancer survivors. Trial registration Clinical Identifier: NCT01476891

  2. Cancer prevention and control interventions using social media: user-generated approaches. (United States)

    Cavallo, David N; Chou, Wen-Ying Sylvia; McQueen, Amy; Ramirez, Amelie; Riley, William T


    Social media are now used by a majority of American internet users. Social media platforms encourage participants to share information with their online social connections and exchange user-generated content. Significant numbers of people are already using social media to share health-related information. As such, social media provide an opportunity for "user-generated" cancer control and prevention interventions that employ users' behavior, knowledge, and existing social networks for the creation and dissemination of interventions. These interventions also enable novel data collection techniques and research designs that will allow investigators to examine real-time behavioral responses to interventions. Emerging social media-based interventions for modifying cancer-related behaviors have been applied to such domains as tobacco use, diet, physical activity, and sexual practices, and several examples are discussed for illustration purposes. Despite some promising early findings, challenges including inadequate user engagement, privacy concerns, and lack of internet access among some groups need to be addressed in future research. Recommendations for advancing the field include stronger partnerships with commercial technology companies, utilization of rapid and adaptive designs to identify successful strategies for user engagement, rigorous and iterative efficacy testing of these strategies, and inclusive methods for intervention dissemination.

    Catterina Ferreccio


    Full Text Available In some Chilean cities, levels of arsenic (As in drinking water reached 800 µg/L between 1950 and 1970, while current levels are 40 µg/L. To evaluate the causal role of this exposure in lung and bladder cancers, we conducted a case-control study in Regions I, II, and III of the country. From 1994 to 1996, cases diagnosed as lung cancer and two hospital controls were entered in the study; one control was a patient with a cancer, while the other was a patient without cancer, both conditions unrelated to As. Controls were matched with cases by age and sex. A standard survey containing questions about residence, employment, health history, was administered to study subjects. Data on As concentrations in water were obtained from records of the municipal water companies. A total of 151 lung cancer cases and 419 controls (167 with cancer and 242 without cancer were enrolled. Median level of lifetime As exposure was significantly higher among cases, with a clear dose-response relationship between mean As exposure levels, with an OR (95% CI of: 1, 1.7 (0.5-5.1, 3.9 (1.2-13.4, 5.5 (2.2-13.5, and 9.0 (3.6-22 for strata one to five respectively. This study provides new evidence that As in drinking water can cause internal cancers and gives an estimate of the form of this relationship.

  6. Educating Low-SES and LEP Survivors About Breast Cancer Research: Pilot Test of the Health Research Engagement Intervention (United States)

    Nickell, Alyssa; Burke, Nancy J.; Cohen, Elly; Caprio, Maria


    The Health Research Engagement Intervention (HREI) aims to reduce information and access disparities for breast cancer research opportunities among low-socioeconomic status (SES) and limited English proficient (LEP) breast cancer survivors by providing neutral, non-trial-specific information about health research via a trusted patient navigator. Qualitative methods in the context of a community-based participatory research design were used to iteratively design the HREI in collaboration with community-based care navigators from a trusted community organization, Shanti Project, and to locate appropriate research studies in collaboration with a web-based trial-matching service, (BCT). Navigators were first trained in clinical trials and health research and then to deliver the HREI, providing feedback that was incorporated into both the HREI design and BCT's interface. Our intervention pilot with low SES and LEP survivors (n=12) demonstrated interest in learning about “health research.” All 12 participants opted to obtain more information when offered the opportunity. Post-intervention questionnaires showed that three of 11 (27 %) participants independently pursued additional information about research opportunities either online or by phone in the week following the intervention. Post-intervention navigator questionnaires indicated that navigators could confidently and efficiently deliver the intervention. LEP patients who pursued information independently faced language barriers. The HREI is a promising and potentially scalable intervention to increase access to neutral information about breast cancer research opportunities for low-SES and LEP individuals. However, in order for it to be effective, systems barriers to participation such as language accessibility at sources of health research information must be addressed. PMID:24744119

  8. Challenges and opportunities in international molecular cancer prevention research: An ASPO Molecular Epidemiology and the Environment and International Cancer Prevention Interest Groups Report. (United States)

    Epplein, Meira; Bostick, Roberd M; Mu, Lina; Ogino, Shuji; Braithwaite, Dejana; Kanetsky, Peter A


    The International Agency for Research on Cancer estimates that over half of the new cancer cases and almost two-thirds of the cancer deaths in 2012 occurred in low and middle income countries. To discuss the challenges and opportunities to reducing the burden of cancer worldwide, the Molecular Epidemiology and the Environment and the International Issues in Cancer Special Interest Groups joined forces to hold a session during the 38th Annual Meeting of the American Society of Preventive Oncology (March 2014, Arlington, Virginia). The session highlighted three topics of particular interest to molecular cancer prevention researchers working internationally, specifically: 1) biomarkers in cancer research; 2) environmental exposures and cancer; and 3) molecular pathological epidemiology. A major factor for successful collaboration illuminated during the discussion was the need for strong, committed, and reliable international partners. A key element of establishing such relationships is to thoroughly involve individual international collaborators in the development of the research question; engaged international collaborators are particularly motivated to champion and shepherd the project through all necessary steps, including issues relating to institutional review boards, political sensitivity, laboratory-based assays, and tumor subtyping. Also essential is allotting time for the building, maintaining, and investing in such relationships so that successful international collaborations may take root and bloom. While there are many challenges inherent to international molecular cancer research, the opportunities for furthering the science and prevention of cancer worldwide are great, particularly at this time of increasing cancer incidence and prevalence in low and middle income countries.

    This project has been performed as cooperative research between KAERI and USNRC. Human factors issues related to soft controls, which is one of key features of advanced HSI, are identified in this project. The issues are analyzed for the evaluation approaches in either experimental or analytical ways. Also, issues requiring additional researches for the evaluation of advanced HSI are identified in the areas of advanced information systems design, computer-based procedure systems, soft controls, human systems interface and plant modernization process, and maintainability of digital systems. The issues are analyzed to discriminate the urgency of researches on it to high, medium, and low levels in consideration of advanced HSI development status in Korea, and some of the issues that can be handled by experimental researches are identified. Additionally, an experimental study is performed to compare operator's performance on human error detection in advanced control rooms vs. in conventional control rooms. It is found that advanced control rooms have several design characteristics hindering operator's error detection performance compared to conventional control rooms.

  13. On the path to translation: Highlights from the 2010 Canadian Conference on Ovarian Cancer Research

    Directory of Open Access Journals (Sweden)

    Thériault Brigitte L


    Full Text Available Abstract Ovarian cancer continues to be the most lethal of the gynaecologic malignancies due to the lack of early detection, screening strategies and ineffective therapeutics for late-stage metastatic disease, particularly in the recurrent setting. The gathering of researchers investigating fundamental pathobiology of ovarian cancer and the clinicians who treat patients with this insidious disease is paramount to meeting the challenges we face. Since 2002, the Canadian Conference on Ovarian Cancer Research, held every two years, has served this essential purpose. The objectives of this conference have been to disseminate new information arising from the most recent ovarian cancer research and identify the most pressing challenges we still face as scientists and clinicians. This is best accomplished through direct encounters and exchanges of innovative ideas among colleagues and trainees from the realms of basic science and clinical disciplines. This meeting has and continues to successfully facilitate rapid networking and establish new collaborations from across Canada. This year, more guest speakers and participants from other countries have extended the breadth of the research on ovarian cancer that was discussed at the meeting. This report summarizes the key findings presented at the fifth biennial Canadian Conference on Ovarian Cancer Research held in Toronto, Ontario, and includes the important issues and challenges we still face in the years ahead to make a significant impact on this devastating disease.

  14. Perceptions of cancer controllability and cancer risk knowledge: the moderating role of race, ethnicity, and acculturation. (United States)

    Ramírez, A Susana; Rutten, Lila J Finney; Oh, April; Vengoechea, Bryan Leyva; Moser, Richard P; Vanderpool, Robin C; Hesse, Bradford W


    Literature suggests racial/ethnic minorities, particularly those who are less-acculturated, have stronger fatalistic attitudes toward cancer than do non-Latino Whites. Knowledge of cancer prevention is also lower among racial/ethnic minorities. Moreover, low knowledge about cancer risk factors is often associated with fatalistic beliefs. Our study examined fatalism and cancer knowledge by race/ethnicity and explored whether race/ethnicity moderate the association of fatalism with knowledge of cancer prevention and risk factors. We analyzed data from the Health Information National Trends Survey (2008), a national probability survey, to calculate population estimates of the associations among race/ethnicity, fatalistic beliefs, and knowledge about cancer from multivariable logistic regression. Racial/ethnic minorities had higher odds of holding fatalistic beliefs and lower odds of having knowledge of cancer risk factors than non-Hispanic Whites, and important differences by acculturation among Latinos were observed. Limited evidence of the moderating effect of race/ethnicity on the relationship between fatalistic beliefs and cancer risk factor knowledge was observed. Knowledge of cancer risk factors is low among all race/ethnicities, while fatalistic beliefs about cancer are higher among racial/ethnic minorities compared with non-Hispanic Whites. Implications for cancer education efforts are discussed.

  19. Stress, cancer and immunity. New developments in biopsychosocial and psychoneuroimmunologic research. (United States)

    Baltrusch, H J; Stangel, W; Titze, I


    Research in biobehavioral oncology has been focused on stress as one dispositional factor in the multifactorial origin and in the clinical progression of malignant disease. New insights into the transduction of environmental influences to the immune system and to other body systems by the brain and neurotransmitters have increased the salience of this approach. Behavioral medicine in the area of cardiovascular disease has been successful due to the introduction of a "Type A" or coronary prone behavior pattern in large epidemiologic studies. This pattern is marked by both psychologic and physiologic hyperresponsiveness. Type A persons appear to be hostile, easily angered, competitive and hard-driving. More recently, behavioral oncologists have similarly attempted at conceptualizing a "Type C" or biopsychosocial cancer risk pattern, as they have noted the denial and suppression of emotions, in particular anger. Other features of this pattern are "pathological niceness", avoidance of conflicts, exaggerated social desirability, harmonizing behavior, over-compliance, over-patience, as well as high rationality and a rigid control of emotional expression ("anti-emotionality"). This pattern, usually concealed behind a facade of pleasantness, appears to be effective as long as environmental and psychological homeostasis is maintained, but collapses in the course of time under the impact of accumulated strains and stressors, especially those evoking feelings of depression and reactions of helplessness and hopelessness. As a prominent feature of this particular coping style, excessive denial, avoidance, suppression and repression of emotions and own basic needs appears to weaken the organism's natural resistance to carcinogenic influences. This may mean that the excessive use of denial and suppression/repression has important psychophysiologic effects linked to tumor biology and host-defense. Recent studies reveal that psychosocial stressors which are met by inadequate and

    Zhou, Xuan; Chen, Lisha; Wang, Anxin; Ma, Yufei; Zhang, Hailu; Zhu, Yimin


    In this paper, a multifunctional peptide-fluorescent-magnetic nanocomposites (Fe₃O₄@PEI@Cy5.5@PEG@HCBP-1 NPs) was synthesized via a layer-by-layer approach for potential application to cancer diagnoses. The multifunctional nanocomposites have great dispersibility and homogeneous particle sizes in aqueous solution. Meanwhile, it has perfect hemocompatibility and satisfying cytocompatibility in a relatively high concentration. Data from in vitro cytotoxicity assay indicated that the nanocomposites could recognize the lung cancer stem cells (CSCs) specifically and enrich the HCBP-1 positive CSCs from H460 tumor xenografts effectively. Additionally, the results of in vivo live fluorescent imaging and magnetic resonance imaging (MRI) showed that the nanocomposites could identify lung CSCs in tumor xenografts. These results suggested that the nanocomposites could be used as a potential cancer diagnostic agent through modifying diverse fluorescence dyes and targeting ligands on its surface.

By using univariate analysis andmutivariate conditional logistic regression analysis, the oddsratio (OR) and its 95 % confidence interval (95 %CI) werecalculated between colorectal cancer and personal habits,dietary factors, as well as intestinal related symptoms.RESULTS: The mutivariate analysis results showed that aftermatched with age, sex and resident location, mucous bloodstool history and mixed sources of drinking water were closelyassociated with colon cancer and rectal cancer, OR values forthe mucous blood stool history were 3.508 (95 %CI: 1.370-8.985) and 2.139 (95 %CI: 1.040-4.402) respectively; for themixed drinking water sources, 2.387 (95 %CI: 1.243-4.587)and 1.951 (95 %CI: 1.086-3.506) respectively. All reachedthe significant level with a P-value less than 0.05.CONCLUSION: The study suggested that mucous bloodstool history and mixed sources of drinking water were therisk factors of colon cancer and rectal cancer. There was noany significant association between dietary habits and theincidence of colorectal cancer.

  2. A Case-Control Study of Risk Factors for Prostate Cancer in Iran

    Directory of Open Access Journals (Sweden)

    Mahmoud Mahmoudi


    Full Text Available Prostate cancer is a major cause of morbidity and mortality in Iran, yet there are few studies examining risk factors specific to the Iranian context. We conducted a case-control study to explore risk factors for prostate cancer in Mazandaran, Iran from 2005 to 2008. The cases were 137 men with clinicopathologically confirmed prostate cancer. Controls were 137 neighborhood and age match men without prostate cancer by PSA and digit examination. Analysis comprised an exploratory stage to identify potential risk factors, defined as variables associated with case status at the P < 0.20 level in conditional logistic regression. A second stage included all potential risk factors in multiple conditional logistic regression analysis, retaining those associated with prostate cancer at the P < 0.05 level. Potential risk factors for prostate cancer in exploratory analysis included family history of prostate cancer, history of other cancer, prostatitis, alcohol consumption, pipe or hookah smoking, walking to work, duration of occupational physical activity, intensity of occupational physical activity, body mass index, and older age. Multivariate analysis found intensity of occupational physical activity, prostatitis, and older age as independent predictors of increased risk for prostate cancer in this Iranian population. Our study confirms several recognized risk factors for prostate cancer, contributes evidence to the discussions of other hypothesized risk factors, and points to potentially new factors. Findings, along with confirmatory studies, can help guide efforts for early detection, treatment, and prevention for this common malignancy that is set to increase in Iran in future decades.

  5. Optimal control on bladder cancer growth model with BCG immunotherapy and chemotherapy (United States)

    Dewi, C.; Trisilowati


    In this paper, an optimal control model of the growth of bladder cancer with BCG (Basil Calmate Guerin) immunotherapy and chemotherapy is discussed. The purpose of this optimal control is to determine the number of BCG vaccine and drug should be given during treatment such that the growth of bladder cancer cells can be suppressed. Optimal control is obtained by applying Pontryagin principle. Furthermore, the optimal control problem is solved numerically using Forward-Backward Sweep method. Numerical simulations show the effectiveness of the vaccine and drug in controlling the growth of cancer cells. Hence, it can reduce the number of cancer cells that is not infected with BCG as well as minimize the cost of the treatment.

  6. Cancer research in need of a scientific revolution: Using 'paradigm shift' as a method of investigation. (United States)

    Wion, Didier; Appaix, Florence; Burruss, Meriwether; Berger, Francois; van der Sanden, Boudewijn


    Despite important human and financial resources and considerable accumulation of scientific publications, patents, and clinical trials, cancer research has been slow in achieving a therapeutic revolution similar to the one that occurred in the last century for infectious diseases. It has been proposed that science proceeds not only by accumulating data but also through paradigm shifts. Here, we propose to use the concept of 'paradigm shift' as a method of investigation when dominant paradigms fail to achieve their promises. The first step in using the 'paradigm shift' method in cancer research requires identifying its founding paradigms. In this review, two of these founding paradigms will be discussed: (i) the reification of cancer as a tumour mass and (ii) the translation of the concepts issued from infectious disease in cancer research. We show how these founding paradigms can generate biases that lead to over-diagnosis and over-treatment and also hamper the development of curative cancer therapies. We apply the 'paradigm shift' method to produce perspective reversals consistent with current experimental evidence. The 'paradigm shift' method enlightens the existence of a tumour physiologic-prophylactic-pathologic continuum. It integrates the target/antitarget concept and that cancer is also an extracellular disease. The 'paradigm shift' method has immediate implications for cancer prevention and therapy. It could be a general method of investigation for other diseases awaiting therapy.

    Johanna Maree


    Full Text Available Background: This integrative review aimed to quantify the publication output of South African cancer nursing research conducted between 2002 and 2012 and to identify key trends relevant to cancer nurse researchers.Objectives: To describe the publication output of cancer nursing research in terms of the journals of publication, authors, focus, participants and methods used, to explore whether the published work was funded and to assess the quality of the studies published.Methods: An integrative review was conducted using the key words South Africa in combination with cancer nursing and oncology nursing to search the databases Pubmed, PsycINFO, CINAHL, Sabinet, Web of Science, Medline and OvidSP. A data extraction sheet was developed to document the required information from each paper and all publications were reviewed independently by the authors.Results: A total of 181 publications for potential inclusion were identified and 26 papers were included in this review. Cervical cancer, specifically the prevention of this disease, was the most popular diagnostic focus and theme of investigation. Most of the studies were descriptive and none of the studies met the criteria of the highest quality.Conclusion: Nursing added to the body of knowledge regarding the primary and secondary prevention of cancer. There is a need for work on both men and women diagnosed withthe most common cancers, as well as the family and care giver. There is also a need for multidisciplinary work using complex interventions focusing on symptom management to improve patient outcomes.

    Full Text Available Ovarian cancer is second prevalent cancer among gynecologic malignancies and the most common type of ovarian cancer is epithelial form (85-90 percent. To detect the risk factors for the epithelial ovarian cancer, a case-control study was conducted in Valieasr hospital in 1988. In this study, 118 cases with epithelial ovarian cancer (according histological records and 240 controls without any gynecological cancer in gynecologic clinic had been interviewed. For data analysis, T-test, Chi2 test and logistic regression have been used at a =0.05 as level of significance. The mean age in cases was 50±13 and in controls was 49.9±12 years, without significant different. The mean number of pregnancies and parity in cases was less than controls, significantly (P<0.03. The mean months of breast feeding in cases was less than controls (54.9±71.2 versus 82.4±62.7 (P<0.001. The cases had a lower mean age of menarch than controls (P=0.03. 58 percent of cases and 21.3 percent of controls hadn't used any contraception methods (P=0.00001. The mean years of contraception was significantly less in cases versus controls (P<0.001. The odds ratio for epithelial ovarian cancer was 0.24 (95 percent CI: 0.13-0.48 in OCP users, 0.47 (95 percent CI: 0.005-0.43 in TL method, and was 0.41 (95 percent CI: 0.22-0.76 in other contraception methods, relative to women who hadn't used any contraception methods. This study reveals that epithelial ovarian cancer risk increases significantly with earlier menarch, decreasing number of pregnancy, deliveries duration of breast feeding and use of contraception methods. Use of contraception pill and tubal ligation method decreases risk of epithelial ovarian cancer.

    Full Text Available Diet plays a vital role in the management of cancer because they are the source of important physiologically functional components. Scientific observations support the idea that dietary supplement can prevent breast cancer recurrences. Strong correlations are established between the high intake of saturated fat and the incidence of different types of cancer. It is found that chronic alcohol consumption is associated with increased risk of cancers of oral cavity, pharynx, esophagus, and larynx. Again, some evidences are also found regarding phosphorous, glutamate level in the body, and incidence of cancer. Different physiologically functional components are found in the dietary materials. Fibers, the major dietary components, have long been recognized for the unique properties in the treatment of cancer, which are related to its antineoplastic functions. Antioxidant rich diet has been added to the list of cancer-preventing dietary components. Also, recently published research has shown that natural carotenoids in the diet leads to a normalization of body epithelial cells and protects against the risk of stomach and esophagus cancer, and improves the immune system′s response. Again, fruit juices, processed vegetable juices, orange peel, green tea, vitamins, flavonoids, and trace materials have cancer inhibitory properties. Clearly, there has been increasing recognition of chemoprotective functions. Now, it can be recognized for another kind of functionality for the improvement of the health of mankind.

    The Szent-Györgyi Prize for Progress in Cancer Research is a prestigious scientific award established by the National Foundation for Cancer Research (NFCR)-a leading cancer research charitable organization in the United States that is committed to supporting innovative cancer research on the global scale that aims to cure cancer. Each year, the Szent-Györgyi Prize honors an outstanding researcher whose original discoveries have expanded our understanding of cancer and resulted in notable advances in cancer prevention, diagnosis, or treatment. The prize also promotes public awareness of the importance of basic cancer research and encourages the sustained investment needed to accelerate the translation of these research discoveries into new cancer treatments. This report highlights the history and mission of the Szent-Györgyi Prize, its role in promoting discovery-oriented cancer research, and the pioneering work led by the 2014 prize winner, Dr. James Alison. Dr. Alison’s work in the area of cancer immunotherapy led to the successful development of immune checkpoint therapy, and the first drug approved by the United States Food and Drug Administration for the treatment of metastatic melanoma.

  12. Maximising the impact of qualitative research in feasibility studies for randomised controlled trials: guidance for researchers. (United States)

    O'Cathain, Alicia; Hoddinott, Pat; Lewin, Simon; Thomas, Kate J; Young, Bridget; Adamson, Joy; Jansen, Yvonne Jfm; Mills, Nicola; Moore, Graham; Donovan, Jenny L


    Feasibility studies are increasingly undertaken in preparation for randomised controlled trials in order to explore uncertainties and enable trialists to optimise the intervention or the conduct of the trial. Qualitative research can be used to examine and address key uncertainties prior to a full trial. We present guidance that researchers, research funders and reviewers may wish to consider when assessing or undertaking qualitative research within feasibility studies for randomised controlled trials. The guidance consists of 16 items within five domains: research questions, data collection, analysis, teamwork and reporting. Appropriate and well conducted qualitative research can make an important contribution to feasibility studies for randomised controlled trials. This guidance may help researchers to consider the full range of contributions that qualitative research can make in relation to their particular trial. The guidance may also help researchers and others to reflect on the utility of such qualitative research in practice, so that trial teams can decide when and how best to use these approaches in future studies.

  13. Research Priorities for Prevention and Control of Noncommunicable Diseases in India

    Full Text Available India is undergoing a demographic and epidemiological transition which is influencing its health. Noncommunicable diseases (NCDs are posing major health and development threats, while we are grappling with communicable diseases and maternal and child health-related issues. The major NCDs include cardiovascular diseases (including stroke, diabetes, cancer, chronic obstructive pulmonary diseases, mental health, and injuries. Tobacco, alcohol, diet, physical inactivity, high blood pressure, and obesity are the major risk factors common to many chronic diseases. Research on NCDs under the ICMR and through other institutions has resulted in the initiation of some national health programs such as National Cancer Control Program and District Mental Health Program. Important epidemiological descriptions have informed us on the causes and distribution of NCDs and their risk factors, including the non-health determinants (poverty, education, employment, etc and health systems assessments, have shown the inadequacies in tackling NCDs. Several global efforts and publications have provided guidance in shaping the research agenda. The special UN NCD Summit held on 19-20 September 2011 brought the world leaders to deliberate on ways to address NCDs in a concerted manner through partnerships. In this paper the authors review the present status of NCDs and their risk factors in the country and propose a strategic research agenda to provide adequate thrust to accelerate research towards a useful outcome.

    Cindy D DAVIS; John A MILNER


    As cancer incidence is projected to increase for decades there is a need for effec-tive preventive strategies. Fortunately, evidence continues to mount that altering dietary habits is an effective and cost-efficient approach for reducing cancer risk and for modifying the biological behavior of tumors. Predictive, validated and sensitive biomarkers, including those that reliably evaluate "intake" or exposure to a specific food or bioactive component, that assess one or more specific bio-logical "effects" that are linked to cancer, and that effectively predict individual "susceptibility" as a function of nutrient-nutrient interactions and genetics, are fundamental to evaluating who will benefit most from dietary interventions. These biomarkers must be readily accessible, easily and reliably assayed, and predictive of a key process(es) involved in cancer. The response to a food is determined not only by the effective concentration of the bioactive food component(s) reaching the target tissue, but also by the amount of the target requiring modification.Thus, this threshold response to foods and their components will vary from indi-vidual to individual. The key to understanding a personalized response is a greater knowledge of nutrigenomics, proteomics and metabolomics.
