The discussion about setting up a program for lung cancer screening was launched with the publication of the results of the National Lung Screening Trial, which suggested reduced mortality in high-risk subjects undergoing CT screening. However, important questions about the benefit-harm balance and the details of a screening program and its cost-effectiveness remain unanswered. A panel of specialists in chest radiology, respiratory medicine, epidemiology, and thoracic surgery representing all...

Background: Inflammatory breast cancer (IBC) represents the most aggressive presentation of breast cancer. Women diagnosed with IBC typically have a poorer prognosis compared with those diagnosed with non-IBC tumors. Recommendations and guidelines published to date on the diagnosis, management, and follow-up of women with breast cancer have focused primarily on non-IBC tumors. Establishing a minimum standard for clinical diagnosis and treatment of IBC is needed.

The American Society of Clinical Oncology (ASCO) has long affirmed that the recognition and management of individuals with an inherited susceptibility to cancer are core elements of oncology care. ASCO released its first statement on genetic testing in 1996 and updated that statement in 2003 and 2010 in response to developments in the field. In 2014, the Cancer Prevention and Ethics Committees of ASCO commissioned another update to reflect the impact of advances in this area on oncology practice. In particular, there was an interest in addressing the opportunities and challenges arising from the application of massively parallel sequencing-also known as next-generation sequencing-to cancer susceptibility testing. This technology introduces a new level of complexity into the practice of cancer risk assessment and management, requiring renewed effort on the part of ASCO to ensure that those providing care to patients with cancer receive the necessary education to use this new technology in the most effective, beneficial manner. The purpose of this statement is to explore the challenges of new and emerging technologies in cancer genetics and provide recommendations to ensure their optimal deployment in oncology practice. Specifically, the statement makes recommendations in the following areas: germline implications of somatic mutation profiling, multigene panel testing for cancer susceptibility, quality assurance in genetic testing, education of oncology professionals, and access to cancer genetic services.

AGU President John Knauss has authorized a panel to revise the existing AGU position statement, which opposes the teaching of creationism or any other religious tenet as science. The current statement, first adopted in December 1981, and most recently reaffirmed in May 1998, is as follows:“The Council of the American Geophysical Union notes with concern the continuing efforts by creationists for administrative, legislative, and juridical actions designed to require or promote the teaching of creationism as a scientific theory. The American Geophysical Union is opposed to all efforts to require or promote the teaching of creationism or any other religious tenet as science.”

Proteomic technologies remain the main backbone of biomarkers discovery in cancer. The continuous development of proteomic technologies also enlarges the bioinformatics domain, thus founding the main pillars of cancer therapy. The main source for diagnostic/prognostic/therapy monitoring biomarker panels are molecules that have a dual role, being both indicators of disease development and therapy targets. Proteomic technologies, such as mass-spectrometry approaches and protein array technologies, represent the main technologies that can depict these biomarkers. Herein, we will illustrate some of the most recent strategies for biomarker discovery in cancer, including the development of immune-markers and the use of cancer stem cells as target therapy. The challenges of proteomic biomarker discovery need new forms of cross-disciplinary conglomerates that will result in increased and tailored access to treatments for patients; diagnostic companies would benefit from the enhanced co-development of companion diagnostics and pharmaceutical companies. In the technology optimization in biomarkers, immune assays are the leaders of discovery machinery. PMID:26565430

Full Text Available Abstract Background We have identified a set of genes whose relative mRNA expression levels in various solid tumors can be used to robustly distinguish cancer from matching normal tissue. Our current feature set consists of 113 gene probes for 104 unique genes, originally identified as differentially expressed in solid primary tumors in microarray data on Affymetrix HG-U133A platform in five tissue types: breast, colon, lung, prostate and ovary. For each dataset, we first identified a set of genes significantly differentially expressed in tumor vs. normal tissue at p-value = 0.05 using an experimentally derived error model. Our common cancer gene panel is the intersection of these sets of significantly dysregulated genes and can distinguish tumors from normal tissue on all these five tissue types. Methods Frozen tumor specimens were obtained from two commercial vendors Clinomics (Pittsfield, MA and Asterand (Detroit, MI. Biotinylated targets were prepared using published methods (Affymetrix, CA and hybridized to Affymetrix U133A GeneChips (Affymetrix, CA. Expression values for each gene were calculated using Affymetrix GeneChip analysis software MAS 5.0. We then used a software package called Genes@Work for differential expression discovery, and SVM light linear kernel for building classification models. Results We validate the predictability of this gene list on several publicly available data sets generated on the same platform. Of note, when analysing the lung cancer data set of Spira et al, using an SVM linear kernel classifier, our gene panel had 94.7% leave-one-out accuracy compared to 87.8% using the gene panel in the original paper. In addition, we performed high-throughput validation on the Dana Farber Cancer Institute GCOD database and several GEO datasets. Conclusions Our result showed the potential for this panel as a robust classification tool for multiple tumor types on the Affymetrix platform, as well as other whole genome arrays
A panel of experts has reviewed the evidence regarding the benefits and harms of screening for lung cancer with low-dose computed tomography (CT) and concluded that the technology may benefit some individuals at high risk for lung cancer. But the panel cautioned that many questions remain about the potential harms of screening and how to translate screening into clinical practice. |

A panel of cell lines of diverse molecular background offers an improved model system for high-content screening, comparative analysis, and cell systems biology. A computational pipeline has been developed to collect images from cell-based assays, segment individual cells and colonies, represent segmented objects in a multidimensional space, and cluster them for identifying distinct subpopulations. While each segmentation strategy can vary for different imaging assays, representation and subpopulation analysis share a common thread. Application of this pipeline to a library of 41 breast cancer cell lines is demonstrated. These cell lines are grown in 2D and imaged through immunofluorescence microscopy. Subpopulations in this panel are identified and shown to correlate with previous subtyping literature that was derived from transcript data.
Full Text Available Abstract Background Variants in numerous genes are thought to affect the success or failure of cancer chemotherapy. Interindividual variability can result from genes involved in drug metabolism and transport, drug targets (receptors, enzymes, etc, and proteins relevant to cell survival (e.g., cell cycle, DNA repair, and apoptosis. The purpose of the current study is to establish a flexible, cost-effective, high-throughput genotyping platform for candidate genes involved in chemoresistance and -sensitivity, and treatment outcomes. Methods We have adopted SNPlex for genotyping 432 single nucleotide polymorphisms (SNPs in 160 candidate genes implicated in response to anticancer chemotherapy. Results The genotyping panels were applied to 39 patients with chronic lymphocytic leukemia undergoing flavopiridol chemotherapy, and 90 patients with colorectal cancer. 408 SNPs (94% produced successful genotyping results. Additional genotyping methods were established for polymorphisms undetectable by SNPlex, including multiplexed SNaPshot for CYP2D6 SNPs, and PCR amplification with fluorescently labeled primers for the UGT1A1 promoter (TAnTAA repeat polymorphism. Conclusion This genotyping panel is useful for supporting clinical anticancer drug trials to identify polymorphisms that contribute to interindividual variability in drug response. Availability of population genetic data across multiple studies has the potential to yield genetic biomarkers for optimizing anticancer therapy.
In March 1999 the Welsh Office asked COMARE to examine two unpublished studies. The first by Busby et al of ''Green Audit'' concluded that there was a significant excess of childhood leukaemia in North Wales associated with residential proximity to the coast. The second study, carried out by Steward et al of the Welsh Cancer Intelligence and Surveillance Unit (WCISU), did not support this conclusion. We were asked to advise as to whether we considered that there was a real raised incidence of childhood leukaemia near the coast of North Wales and whether further study was required. To do this we initially organised a comparison of the figures quoted by both the Green Audit and WCISU with the database held by the Childhood Cancer Research Group (CCRG) in Oxford. This group maintains the National Registry of Childhood Tumours (NRCT), data for which are supplied from a variety of sources including cancer registries but also directly from medical cancer specialists as well as from death certificates. As a consequence this provides an independent check on much of the data on childhood cancer held by cancer registries in Great Britain and is clinically validated. After carrying out the independent check on the number of cases of childhood leukaemia in these Welsh counties it was immediately apparent that the data held by Green Audit, on which the analysis by Busby et al was based, were incorrect. These data were received from the Welsh Cancer Registry (WCR) in 1995. A further data set was received from WCR in 1996 but was not used in the analysis by Busby et al. In June 1999 we issued a statement to the Welsh Office. In that statement we noted that Dr Busby and his colleagues appeared to have used erroneous data in their study. On the basis of the Steward et al data, COMARE also stated that we found no evidence to support the contention that there is an increased incidence of childhood leukaemia or other childhood cancers amongst the Welsh population living close to the
Full text: Introduction at the Panel discussion: I'm really not prepared to make any policy statements at this stage because the multi-lateral-informational exercises on this topic are still taking their form. I may just briefly mention what the Agency has been doing on this topic during the last six months or so. Last May we had an advisory group meeting in Vienna with a topic 'Research Reactor Renewal and Upgrading Program', but did not consider only fuel cycle questions but also other matters of interest. The outcome of this meeting will be submitted to the International Nuclear Fuel Cycle Evaluation Working Group. We have just published the proceedings of this meeting which is the 'Agency Technical Document, No. 214'. This is a cost-free publication that we can send to any one of you who wishes to have it and the secretaries at the Information Desk have an order list so during the break if you just please write down your name and address we shall then send the document to you. Some sort of continuation to that meeting and also a continuation to the discussion that we have had here yesterday and today, we are planning to have a consultant's meeting in preparation of the program on research reactor core conversions to use low enriched uranium instead of highly enriched uranium. This exercise has been coordinated with INFCE and it is not the intention that work would be duplicating each other but rather all meeting at the end of November, early December, is something that we would like to look at concrete cases i mainly developing countries that are currently utilizing highly enriched uranium so that we would like to make some sort of a check list or technical evaluation of what must be done in certain country cases to prepare core conversions that would utilize the new fuel designs that have been discussed here yesterday and today. We also hope that during the meeting in about three weeks, we could discuss some demonstration projects or programs that could take

BACKGROUND African–American men with prostate cancer (PCa) present with higher-grade and -stage tumors compared to Caucasians. While the disparity may result from multiple factors, a biological basis is often strongly suspected. Currently, few well-characterized experimental model systems are available to study the biological basis of racial disparity in PCa. We report a validated in vitro cell line model system that could be used for the purpose. METHODS We assembled a PCa cell line model that included currently available African–American PCa cell lines and LNCaP (androgen-dependent) and C4-2 (castration-resistant) Caucasian PCa cells. The utility of the cell lines in studying the biological basis of variance in a malignant phenotype was explored using a multiplex biomarker panel consisting of proteins that have been proven to play a role in the progression of PCa. The panel expression was evaluated by Western blot and RT-PCR in cell lines and validated in human PCa tissues by RT-PCR. As proof-of-principle to demonstrate the utility of our model in functional studies, we performed MTS viability assays and molecular studies. RESULTS The dysregulation of the multiplex biomarker panel in primary African–American cell line (E006AA) was similar to metastatic Caucasian cell lines, which would suggest that the cell line model could be used to study an inherent aggressive phenotype in African–American men with PCa. We had previously demonstrated that Protein kinase D1 (PKD1) is a novel kinase that is down regulated in advanced prostate cancer. We established the functional relevance by over expressing PKD1, which resulted in decreased proliferation and epithelial mesenchymal transition (EMT) in PCa cells. Moreover, we established the feasibility of studying the expression of the multiplex biomarker panel in archived human PCa tissue from African–Americans and Caucasians as a prelude to future translational studies. CONCLUSION We have characterized a novel in
Full text: I want to focus on the two questions related to decommissioning and waste management posed to the panel, that I would like to restate as a question: Is it possible to decommission a nuclear facility and deal with the related wastes in case of absence of a final waste repository? My answer to this question is: the decommissioning of a nuclear facility is possible and should be pursued as far ahead of time as possible. The reasons for this statement are many. The most important ones are safety and costs. A nuclear power plant, at the moment of final shutdown, has thousands of square metres of contaminated surfaces, thousands of tonnes of activated materials and normally also many cubic metres of radioactive liquids that must continue to be kept isolated from the environment. This means continued and extensive maintenance and surveillance. First, decommissioning actions, that is decontamination and liquid waste solidification, should be carried out to reduce risk, maintenance and surveillance, and to minimize the production of additional operational wastes. Other decommissioning actions can minimize the volume and surface of wastes. The best, of course, would be to proceed also with waste conditioning. Is this possible without the availability of a repository? In my opinion - particularly if we are referring to a repository with engineered barriers - this is possible with minimum financial risk, on the basis of a clear definition of the areas of responsibility between waste producers and the body in charge of the repository. Let us analyse the problem in more detail. Today the average dimensions of a waste package and the expected radioactivity content are basically standardized. The data to be collected, in order for adequate waste package characterization, are also generally known. Even better is if the data are collected according to the guidance in certain IAEA publications, such as the one being published on record keeping and one on waste inventory

Tuberculosis is a major cause of morbidity and mortality in women of childbearing age (15-44 years). Despite increased tuberculosis risk during pregnancy, optimal clinical treatment remains unclear: safety, tolerability, and pharmacokinetic data for many tuberculosis drugs are lacking, and trials of promising new tuberculosis drugs exclude pregnant women. To advance inclusion of pregnant and postpartum women in tuberculosis drug trials, the US National Institutes of Health convened an international expert panel. Discussions generated consensus statements (>75% agreement among panelists) identifying high-priority research areas during pregnancy, including: (1) preventing progression of latent tuberculosis infection, especially in women coinfected with human immunodeficiency virus; (2) evaluating new agents/regimens for treatment of multidrug-resistant tuberculosis; and (3) evaluating safety, tolerability and pharmacokinetics of tuberculosis drugs already in use during pregnancy and postpartum. Incorporating pregnant women into clinical trials would extend evidence-based tuberculosis prevention and treatment standards to this special population. PMID:26658057

Full Text Available Abstract Background The presence of cancer-specific DNA methylation patterns in epithelial colorectal cells in human feces provides the prospect of a simple, non-invasive screening test for colorectal cancer and its precursor, the adenoma. This study investigates a panel of epigenetic markers for the detection of colorectal cancer and adenomas. Methods Candidate biomarkers were subjected to quantitative methylation analysis in test sets of tissue samples from colorectal cancers, adenomas, and normal colonic mucosa. All findings were verified in independent clinical validation series. A total of 523 human samples were included in the study. Receiver operating characteristic (ROC curve analysis was used to evaluate the performance of the biomarker panel. Results Promoter hypermethylation of the genes CNRIP1, FBN1, INA, MAL, SNCA, and SPG20 was frequent in both colorectal cancers (65-94% and adenomas (35-91%, whereas normal mucosa samples were rarely (0-5% methylated. The combined sensitivity of at least two positives among the six markers was 94% for colorectal cancers and 93% for adenoma samples, with a specificity of 98%. The resulting areas under the ROC curve were 0.984 for cancers and 0.968 for adenomas versus normal mucosa. Conclusions The novel epigenetic marker panel shows very high sensitivity and specificity for both colorectal cancers and adenomas. Our findings suggest this biomarker panel to be highly suitable for early tumor detection.
EFSA Panel on Plant Health (PLH
Full Text Available Following a request from the European Commission, the EFSA Panel on Plant Health (EFSA PLH Panel was asked to react to a document entitled “Comments on the European Union Food Safety Authority’s Pest Risk Assessment for Phyllosticta citricarpa”, authored by Hattingh et al., which was posted online in August 2014 on the website of Citrus Research International (Pty Ltd, South Africa. Citrus black spot (CBS, caused by the fungus Phyllosticta citricarpa (McAlpine Van der Aa, is a fruit-blemishing and leaf-spotting disease affecting citrus. P. citricarpa is not known to occur in the EU territory and is regulated as a quarantine organism in citrus (Council Directive 2000/29/EC. The Panel assessed the comments by Hattingh et al. in the light of the content of the EFSA PLH Panel Scientific Opinion on CBS and the EFSA report detailing responses to comments received during the public consultation on the draft opinion. The Panel stands by the EFSA PLH Panel Scientific Opinion on CBS and considers that the comments by Hattingh et al. have been thoroughly addressed in the EFSA report on the public consultation on the EFSA PLH Panel Scientific Opinion on CBS. A detailed point by point reply to the comments by Hattingh et al. is provided in an Appendix of this Panel statement. Since September 2014, EFSA has written to the lead author of the comments trying to engage in a scientific dialogue concerning the sources of uncertainty related to the risks posed by P. citricarpa to plant health in the EU, so as to identify ways to reduce such uncertainties (e.g. with further research and/or data exchange. The EFSA PLH Panel also remains open to such constructive dialogue in the future.

To spread the National Comprehensive Cancer Network(NCCN)guidelines widely in Asia, committee members from Asian countries have been preparing an Asia Consensus Statement(ACS)along the NCCN guidelines. The ACS for Kidney Cancer guidelines and Prostate Cancer guidelines were issued in 2009 and in 2011, respectively. In addition, second versions of both these guidelines were issued in 2011 and 2013, respectively. In this review, the process and contents of NCCN ACS have been described. PMID:25129079
Full Text Available Detecting breast cancer at early stages can be challenging. Traditional mammography and tissue microarray that have been studied for early breast cancer detection and prediction have many drawbacks. Therefore, there is a need for more reliable diagnostic tools for early detection of breast cancer due to a number of factors and challenges. In the paper, we presented a five-marker panel approach based on SVM for early detection of breast cancer in peripheral blood and show how to use SVM to model the classification and prediction problem of early detection of breast cancer in peripheral blood. We found that the five-marker panel can improve the prediction performance (area under curve in the testing data set from 0.5826 to 0.7879. Further pathway analysis showed that the top four five-marker panels are associated with signaling, steroid hormones, metabolism, immune system, and hemostasis, which are consistent with previous findings. Our prediction model can serve as a general model for multibiomarker panel discovery in early detection of other cancers.

Full Text: Good afternoon, Ladies and Gentlemen, I welcome you all to this IAEA event marking World Cancer Day 2013. I am very pleased that we have with us today Professor Kutluk, President-Elect of the Union of International Cancer Control, which initiated World Cancer Day. I also welcome the distinguished Ambassador of Sudan, H.E. Mr. Mahmoud Hassan El Amin, and Dr. Munki Lee, Minister, Permanent Mission of the Republic of Korea, as well as our own Medical Director Dr. Matthias Lademann. Many events are being held around the world today to draw attention to cancer. This year, there is a special focus on dispelling common misconceptions about the disease. One of the most persistent myths about cancer is that it is mainly a disease of wealthy countries. In fact, around 70 percent of cancer deaths occur in developing countries. Another myth is that cancer is invariably a death sentence. In reality, many cancers respond well to treatment and can even be cured. Thanks to early detection and modern treatment methods, millions of men and women now live normal lives for many decades after diagnosis. Often, they die in old age of something other than cancer. Here in Austria, as in all developed countries, we take access to radiotherapy for granted. But the picture is very different in developing countries. It is estimated that there is a shortage of around 5 000 radiotherapy machines in developing countries. That means that millions of people, in Africa and elsewhere, have no access to diagnostic services or treatment. Too many die of conditions that are actually treatable. That is an immense human tragedy. The IAEA Programme of Action for Cancer Therapy - PACT - has been working hard to try to make radiotherapy services available in all countries. Through our Technical Cooperation programme, we are supporting over 130 projects in cancer diagnosis, management and treatment. We help countries to establish oncology and radiotherapy centres. We provide extensive training for
Full text: Good afternoon, Ladies and Gentlemen. Welcome to this IAEA event marking World Cancer Day 2012. The Agency's work in cancer control has been a high priority for me since I became Director General just over two years go. When I travel to developing countries, I try wherever possible to see IAEA cancer control projects in action. This is always very uplifting. In June and July last year, I visited a number of Latin American countries to discuss IAEA support for their cancer control efforts. In July, I went to the Mother Teresa Hospital in Tirana, Albania, where IAEA support has helped to significantly improve radiotherapy services and provided training for 23 health professionals to launch a breast cancer screening programme. In October, I had the opportunity to celebrate the opening of a new cancer therapy facility in Indonesia. Also in October, I travelled to Vietnam. I visited the Tran Hung Dao hospital in Hanoi and saw some of the most high-tech cancer treatment equipment in use there. The IAEA had facilitated the donation of a radiotherapy unit from India to Vietnam in May 2010. It was very impressive to witness how quickly a country's cancer control capabilities can be transformed. There are many such success stories throughout the world. But, of course, the need is great and there is still much work to be done. For example, there is a shortage of around 5 000 radiotherapy machines in low and middle income countries. This means that hundreds of thousands of patients are denied diagnosis and treatment that could save their lives. The IAEA Programme of Action for Cancer Therapy - PACT - has been working hard to try to make radiotherapy services available in all countries. The IAEA technical cooperation programme remains a major mechanism for providing assistance to Member States. The Agency is supporting over 130 projects in cancer diagnosis, management and treatment. Oncology and radiotherapy centres are being established in countries such as

We are developing a novel, portable dual-panel positron emission tomography (PET) camera dedicated to breast cancer imaging. With a sensitive area of approximately 150 cm(2), this camera is based on arrays of lutetium oxyorthosilicate (LSO) crystals (1x1x3 mm(3)) coupled to 11x11-mm(2) position-sensitive avalanche photodiodes (PSAPD). GATE open source software was used to perform Monte Carlo simulations to optimize the parameters for the camera design. The noise equivalent counting (NEC) rate, together with the true, scatter, and random counting rates were simulated at different time and energy windows. Focal plane tomography (FPT) was used for visualizing the tumors at different depths between the two detector panels. Attenuation and uniformity corrections were applied to images. PMID:17646005
41 reported diagnoses of cancer (EKN 2010b). The EKN established in (EKN 2010b) that after correction for multiple testing the results for all the municipalities of the district of Wolfenbuettel other than the Samtgemeinde Asse were not significant. The only significant findings were the results for leukaemia and thyroid cancer in the Samtgemeinde Asse. The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) wrote to the Commission on Radiological Protection (SSK) on 20 December 2010 requesting a statement on the results of the EKN's analysis of the incidence of cancer in the Samtgemeinde Asse.

Resistance to endocrine therapy is a major complication of luminal breast cancer and studies of the biological features of hormonal resistance are limited by the lack of adequate preclinical models. The aim of this study is to establish and characterize a panel of primary human luminal breast carcinoma xenografts, and to evaluate their response to endocrine therapies. Four hundred and twenty-three tumor fragments obtained directly from patients have been grafted in the interscapular fatpad of Swiss nude mice. After stable engraftment with estradiol supplementation, xenografted tumors have been validated by conventional pathology and immunohistochemistry examination, and additional molecular studies. In vivo tumor growth and response to different endocrine treatments were evaluated. We have engrafted 423 tumors including 314 ER+ tumors, and 8 new luminal breast cancer xenografts have been obtained (2.5%). Tumor take was much lower for luminal tumors than for non-luminal tumors (2.5 vs. 24.7%, P < 0.0001), and was associated with two independent criteria, i.e., ER status (P < 0.0001) and a high grade tumor (P = 0.05). Histological and immunohistochemical analyses performed on patient's tumors and xenografts showed striking similarities in the tumor morphology as well as in the expression level of ER, PR, and HER2. Response to hormone therapy, evaluated in 6 luminal models, showed different sensitivities, thus exhibiting heterogeneity similar to what is observed in the clinic. We have established a panel of primary human luminal breast cancer xenografts, recapitulating the biological and clinical behaviors of patient tumors, and therefore suitable for further preclinical experiments.

Detection of breast cancer at an early stage is the key for successful treatment and improvement of outcome. However the limitations of mammography are well recognized, especially for those women with premenopausal breast cancer. Novel approaches to breast cancer screening are necessary, especially in the developing world where mammography is not feasible. In this study, we examined the promoter methylation of six genes (SFN, P16, hMLH1, HOXD13, PCDHGB7 and RASSF1a) in circulating free DNA (cfDNA) extracted from serum. We used a high-throughput DNA methylation assay (MethyLight) to examine serum from 749 cases including breast cancer patients, patients with benign breast diseases and healthy women. The six-gene methylation panel test achieved 79.6% and 82.4% sensitivity with a specificity of 72.4% and 78.1% in diagnosis of breast cancer when compared with healthy and benign disease controls, respectively. Moreover, the methylation panel positive group showed significant differences in the following independent variables: (a) involvement of family history of tumors; (b) a low proliferative index, ki-67; (c) high ratios in luminal subtypes. Additionally the panel also complemented some breast cancer cases which were neglected by mammography or ultrasound. These data suggest that epigenetic markers in serum have potential for diagnosis of breast cancer. PMID:26918343

Recently prostate and ovarian cancer has been related to milk consumption. However, existing observational studies based on country level data do not attempt to identify causal effects since they are only based on simple cross-sectional analyses. This paper takes a step toward estimating of causal effects of milk consumption on cancer by applying panel econometric models and by using the within-country variation of the mortality rates and food consumption instead of the between-country variat...
As the leading organization representing cancer specialists involved in patient care and clinical research, the American Society of Clinical Oncology (ASCO) reaffirms its commitment to integrating cancer risk assessment and management, including molecular analysis of cancer predisposition genes, into the practice of oncology and preventive medicine. The primary goal of this effort is to foster expanded access to, and continued advances in, medical care provided to patients and families affected by hereditary cancer syndromes. The 1996 ASCO Statement on Genetic Testing for Cancer Susceptibility set forth specific recommendations relating to clinical practice, research needs, educational opportunities, requirement for informed consent, indications for genetic testing, regulation of laboratories, and protection from discrimination, as well as access to and reimbursement for cancer genetics services. In updating this Statement, ASCO endorses the following principles: Indications for Genetic Testing: ASCO recommends that genetic testing be offered when 1) the individual has personal or family history features suggestive of a genetic cancer susceptibility condition, 2) the test can be adequately interpreted, and 3) the results will aid in diagnosis or influence the medical or surgical management of the patient or family members at hereditary risk of cancer. ASCO recommends that genetic testing only be done in the setting of pre- and post-test counseling, which should include discussion of possible risks and benefits of cancer early detection and prevention modalities. Special Issues in Testing Children for Cancer Susceptibility: ASCO recommends that the decision to offer testing to potentially affected children should take into account the availability of evidence-based risk-reduction strategies and the probability of developing a malignancy during childhood. Where risk-reduction strategies are available or cancer predominantly develops in childhood, ASCO believes that
The development of colorectal cancer (CRC) is accompanied by extensive epigenetic changes, including frequent regional hypermethylation particularly of gene promoter regions. Specific genes, including SEPT9, VIM1 and TMEFF2 become methylated in a high fraction of cancers and diagnostic assays for detection of cancer-derived methylated DNA sequences in blood and/or fecal samples are being developed. There is considerable potential for the development of new DNA methylation biomarkers or panels to improve the sensitivity and specificity of current cancer detection tests. Combined epigenomic methods – activation of gene expression in CRC cell lines following DNA demethylating treatment, and two novel methods of genome-wide methylation assessment – were used to identify candidate genes methylated in a high fraction of CRCs. Multiplexed amplicon sequencing of PCR products from bisulfite-treated DNA of matched CRC and non-neoplastic tissue as well as healthy donor peripheral blood was performed using Roche 454 sequencing. Levels of DNA methylation in colorectal tissues and blood were determined by quantitative methylation specific PCR (qMSP). Combined analyses identified 42 candidate genes for evaluation as DNA methylation biomarkers. DNA methylation profiles of 24 of these genes were characterised by multiplexed bisulfite-sequencing in ten matched tumor/normal tissue samples; differential methylation in CRC was confirmed for 23 of these genes. qMSP assays were developed for 32 genes, including 15 of the sequenced genes, and used to quantify methylation in tumor, adenoma and non-neoplastic colorectal tissue and from healthy donor peripheral blood. 24 of the 32 genes were methylated in >50% of neoplastic samples, including 11 genes that were methylated in 80% or more CRCs and a similar fraction of adenomas. This study has characterised a panel of 23 genes that show elevated DNA methylation in >50% of CRC tissue relative to non-neoplastic tissue. Six of these genes
Full Text Available Colorectal cancer (CRC is the third common carcinoma with a high rate of mortality worldwide and several studies have investigated some molecular and clinicopathological markers for diagnosis and prognosis of its malignant phenotypes. The aim of this study is to evaluate expression frequency of PAGE4, SCP-1, and SPANXA/D cancer testis antigen (CTA genes as well as some clinical risk markers to predict liver metastasis of colorectal cancer patients. The expression frequency of PAGE4, SCP-1, and SPANXA/D cancer/testis antigen (CTA genes was obtained using reverse transcription polymerase chain reaction (RT-PCR assay in 90 colorectal tumor samples including both negative and positive liver metastasis tumors. Statistical analysis was performed to assess the association of three studied genes and clinical risk factors with CRC liver metastasis. The frequency of PAGE4 and SCP-1 genes expression was significantly higher in the primary tumours with liver metastasis when statistically compared with primary tumors with no liver metastasis (P<0.05. Among all clinical risk factors studied, the lymph node metastasis and the depth of invasion were statistically correlated with liver metastasis of CRC patients. In addition, using multiple logistic regression, we constructed a model based on PAGE4 and lymph node metastasis to predict liver metastasis of CRC.

This document is a summary statement of the outcome from the meeting: “Bisphenol A: An Examination of the Relevance of Ecological, In vitro and Laboratory Animal Studies for Assessing Risks to Human Health” sponsored by both the NIEHS and NIDCR at NIH/DHHS, as well as the US-EPA and Commonweal on the estrogenic environmental chemical bisphenol A (BPA, 2,2-bis(4-hydroxyphenyl)propane; CAS# 80-05-7). The meeting was held in Chapel Hill, NC, 28–30 November 2006 due to concerns about the potential for a relationship between BPA and negative trends in human health that have occurred in recent decades. Examples include increases in abnormal penile/urethra development in males, early sexual maturation in females, an increase in neurobehavioral problems such as attention deficit hyperactivity disorder (ADHD) and autism, an increase in childhood and adult obesity and type 2 diabetes, a regional decrease in sperm count, and an increase in hormonally mediated cancers, such as prostate and breast cancers. Concern has been elevated by published studies reporting a relationship between treatment with “low doses” of BPA and many of theses negative health outcomes in experimental studies in laboratory animals as well as in vitro studies identifying plausible molecular mechanisms that could mediate such effects. Importantly, much evidence suggests that these adverse effects are occurring in animals within the range of exposure to BPA of the typical human living in a developed country, where virtually everyone has measurable blood, tissue and urine levels of BPA that exceed the levels produced by doses used in the “low dose” animal experiments.

Proteomic analyses of readily obtained human fluids (e.g., serum, urine, and saliva) indicate that the diagnosis of complex diseases will be enhanced by the simultaneous measurement of multiple biomarkers from such samples. This paper describes the development of a nanoparticle-based multiplexed platform that has the potential for simultaneous read-out of large numbers of biomolecules. For this purpose, we have chosen pancreatic adenocarcinoma (PA) as a test bed for diagnosis and prognosis. PA is a devastating form of cancer in which an estimated 86% of diagnoses resulted in death in the United States in 2010. The high mortality rate is due, in part, to the asymptomatic development of the disease and the dearth of sensitive diagnostics available for early detection. One promising route lies in the development of a serum biomarker panel that can generate a signature unique to early stage PA. We describe the design and development of a proof-of-concept PA biomarker immunoassay array coupled with surface-enhanced Raman scattering (SERS) as a sensitive readout method. PMID:23150876
Full Text Available This consensus statement is organized into six parts: 1 Definitions: cancer-related depressed mood state is defined as a group of depressive symptoms, rather than major depressive disorder. Thus, “cancer-related depression” or “depressed mood state” is introduced as standard terminology and associated with the Chinese medicine concept of “yu zheng” (depression syndrome. 2 Pathogenesis: factors including psychological stress, cancer pain, cancer fatigue, sleep disorders, surgery trauma, chemotherapy, and radiation therapy are strongly associated with cancer-related depressed mood state. Crucial elements of pathogenesis are cancer caused by depression, depression caused by cancer, and the concurrence of phlegm, dampness, and stasis from constrained liver-qi and spleen deficiency. 3 Symptoms: these include core symptoms, psychological symptoms, and somatic symptoms. Depressed mood and loss of interest are the main criteria for diagnosis. 4 Clinical evaluation: based on the Mini-International Neuropsychiatric Interview and a numeric rating scale, and taking mood changes during cancer diagnosis and treatment into consideration, a questionnaire can be drafted to distinguish between major depressive disorder and cancer-related depression. The aim is to assist oncology clinicians to identify, treat, and refer patients with cancer-related depression. 5 Diagnosis: diagnosis should be based on the Chinese Classification for Mental Disorders (CCMD-3, taking patients' mood changes during diagnosis and treatment into consideration. 6 Treatment: treatments for cancer-related depression must be performed concurrently with cancer treatment. For mild depression, non-pharmacologic comprehensive therapies, including psychological intervention, music therapy, patient education, physical activity, and acupuncture, are recommended; for moderate depression, classical Chinese herbal formulas based on syndrome pattern differentiation combined with

Societal perceptions may factor into the high rates of nontreatment in patients with lung cancer. To determine whether bias exists toward lung cancer, a study using the Implicit Association Test method of inferring subconscious attitudes and stereotypes from participant reaction times to visual cues was initiated. Participants were primarily recruited from an online survey panel based on US census data. Explicit attitudes regarding lung and breast cancer were derived from participants' ratings (n = 1778) regarding what they thought patients experienced in terms of guilt, shame, and hope (descriptive statements) and from participants' opinions regarding whether patients ought to experience such feelings (normative statements). Participants' responses to descriptive and normative statements about lung cancer were compared with responses to statements about breast cancer. Analyses of responses revealed that the participants were more likely to agree with negative descriptive and normative statements about lung cancer than breast cancer (Plung cancer compared with breast cancer; mean response times in the lung cancer/negative conditions were significantly shorter than in the lung cancer/positive conditions (Pcaregivers, healthcare providers, and members of the general public had comparable levels of negative implicit attitudes toward lung cancer. These results show that lung cancer was stigmatized by patients, caregivers, healthcare professionals, and the general public. Further research is needed to investigate whether implicit and explicit attitudes and stereotypes affect patient care. PMID:26698307

Abstract Background Lung cancer is the leading cause of cancer death in men and women in the United States and Western Europe. Over 160,000 Americans die of this disease every year. The five-year survival rate is 15% – significantly lower than that of other major cancers. Early detection is a key factor in increasing lung cancer patient survival. DNA hypermethylation is recognized as an important mechanism for tumor suppressor gene inactivation in cancer and could yield powerful biomarkers fo...

Only a minority of prostate cancers lead to death. Because no tissue biomarkers of aggressiveness other than Gleason score are available at diagnosis, many nonlethal cancers are treated aggressively. We evaluated whether a panel of biomarkers, associated with a range of disease outcomes in previous studies, could predict death from prostate cancer for men with localized disease. Using a case-only design, subjects were identified from three Australian epidemiological studies. Men who had died of their disease, “cases” (N = 83), were matched to “referents” (N = 232), those who had not died of prostate cancer, using incidence density sampling. Diagnostic tissue was retrieved to assess expression of AZGP1, MUC1, NKX3.1, p53, and PTEN by semiquantitative immunohistochemistry (IHC). Poisson regression was used to estimate mortality rate ratios (MRRs) adjusted for age, Gleason score, and stage and to estimate survival probabilities. Expression of MUC1 and p53 was associated with increased mortality (MRR 2.51, 95% CI 1.14–5.54, P = 0.02 and 3.08, 95% CI 1.41–6.95, P = 0.005, respectively), whereas AZGP1 expression was associated with decreased mortality (MRR 0.44, 95% CI 0.20–0.96, P = 0.04). Analyzing all markers under a combined model indicated that the three markers were independent predictors of prostate cancer death and survival. For men with localized disease at diagnosis, assessment of AZGP1, MUC1, and p53 expression in diagnostic tissue by IHC could potentially improve estimates of risk of dying from prostate cancer based only on Gleason score and clinical stage

Patients in specific vulnerable population groups suffer disproportionately from cancer. The elimination of cancer disparities is critically important for lessening the burden of cancer. The Patient Protection and Affordable Care Act provides both opportunities and challenges for addressing cancer care disparities and access to care. The American Society of Clinical Oncology (ASCO) advocates for policies that ensure access to cancer care for the underserved. Such policies include insurance reform and the reduction of economic barriers to quality health care. Building on ASCO's prior statement on disparities in cancer care (2009), this article summarizes elements of the health care law that are relevant to cancer disparities and provides recommendations for addressing major provisions in the law. It outlines specific strategies to address insurance reform, access to care, quality of care, prevention and wellness, research on health care disparities, and diversity in the health care workforce. ASCO is committed to leading efforts toward the improvement of cancer care among the most vulnerable patients. PMID:21810680
Full Text Available Abstract Background Lapatinib, a tyrosine kinase inhibitor of HER2 and EGFR and is approved, in combination with capecitabine, for the treatment of trastuzumab-refractory metastatic breast cancer. In order to establish a possible gene expression response to lapatinib, a panel of breast cancer cell lines with varying sensitivity to lapatinib were analysed using a combination of microarray and qPCR profiling. Methods Co-inertia analysis (CIA, a data integration technique, was used to identify transcription factors associated with the lapatinib response on a previously published dataset of 96 microarrays. RNA was extracted from BT474, SKBR3, EFM192A, HCC1954, MDAMB453 and MDAMB231 breast cancer cell lines displaying a range of lapatinib sensitivities and HER2 expression treated with 1 μM of lapatinib for 12 hours and quantified using Taqman RT-PCR. A fold change ≥ ± 2 was considered significant. Results A list of 421 differentially-expressed genes and 8 transcription factors (TFs whose potential regulatory impact was inferred in silico, were identified as associated with lapatinib response. From this group, a panel of 27 genes (including the 8 TFs were selected for qPCR validation. 5 genes were determined to be significantly differentially expressed following the 12 hr treatment of 1 μM lapatinib across all six cell lines. Furthermore, the expression of 4 of these genes (RB1CC1, FOXO3A, NR3C1 and ERBB3 was directly correlated with the degree of sensitivity of the cell line to lapatinib and their expression was observed to “switch” from up-regulated to down-regulated when the cell lines were arranged in a lapatinib-sensitive to insensitive order. These included the novel lapatinib response-associated genes RB1CC1 and NR3C1. Additionally, Cyclin D1 (CCND1, a common regulator of the other four proteins, was also demonstrated to observe a proportional response to lapatinib exposure.

Mutations in the epidermal growth factor receptor gene (EGFR) represent one of the most frequent "actionable" alterations in non-small cell lung cancer (NSCLC). Typified by high response rates to targeted therapies, EGFR tyrosine kinase inhibitors (TKIs) are now established first-line treatment options and have transformed the treatment paradigm for NSCLC. With the recent breakthrough designation and approval of the third-generation EGFR TKI osimertinib, available systemic and local treatment options have expanded, requiring new clinical algorithms that take into account individual patient molecular and clinical profiles. In this International Association for the Study of Lung Cancer commissioned consensus statement, key pathologic, diagnostic, and therapeutic considerations, such as optimal choice of EGFR TKI and management of brain metastasis, are discussed. In addition, recommendations are made for clinical guidelines and research priorities, such as the role of repeat biopsies and use of circulating free DNA for molecular studies. With the rapid pace of progress in treating EGFR-mutant NSCLC, this statement provides a state-of-the-art review of the contemporary issues in managing this unique subgroup of patients. PMID:27229180

Full Text Available Glioblastoma (GBM is an aggressive, malignant brain tumor typically resulting in death of the patient within one year following diagnosis; and those who survive beyond this point usually present with tumor recurrence within two years (5-year survival is 5%. The genetic heterogeneity of GBM has made the molecular characterization of these tumors an area of great interest and has led to identification of molecular subtypes in GBM. The availability of sequencing platforms that are both fast and economical can further the adoption of tumor sequencing in the clinical environment, potentially leading to identification of clinically actionable genetic targets. In this pilot study, comprised of triplet samples of normal blood, primary tumor, and recurrent tumor samples from three patients; we compared the ability of Illumina whole exome sequencing (ExomeSeq and the Ion AmpliSeq Comprehensive Cancer Panel (CCP to identify somatic variants in patient-paired primary and recurrent tumor samples. Thirteen genes were found to harbor variants, the majority of which were exclusive to the ExomeSeq data. Surprisingly, only two variants were identified by both platforms and they were located within the PTCH1 and NF1 genes. Although preliminary in nature, this work highlights major differences in variant identification in data generated from the two platforms. Additional studies with larger samples sizes are needed to further explore the differences between these technologies and to enhance our understanding of the clinical utility of panel based platforms in genomic profiling of brain tumors.

Background Germline DNA mutations that increase the susceptibility of a patient to certain cancers have been identified in various genes, and patients can be screened for mutations in these genes to assess their level of risk for developing cancer. Traditional methods using Sanger sequencing focus on small groups of genes and therefore are unable to screen for numerous genes from several patients simultaneously. The goal of the present study was to validate a 25-gene panel to assess genetic r...
In answer to a House of Commons question, this piece from Hansard for 16th June 1994 looks at the incidence of cancer around the Trawsfynydd and Wylfa nuclear installations in Wales. A study undertaken between 1974 and 1986 followed groupings of many cancers, especially leukaemias, lymphoid leukaemia, lymphomas, Hodgkin's disease, multiple myeloma, brain and thyroid cancers. These were chosen because of their suggested links with radiation in the medical literature. No statistically significant links were found between the incidence of cancers studied and residence near the nuclear stations. (UK).
Full Text Available Prostate epithelial cells from both normal and cancer tissues, grown in three-dimensional (3D culture as spheroids, represent promising in vitro models for the study of normal and cancer-relevant patterns of epithelial differentiation. We have developed the most comprehensive panel of miniaturized prostate cell culture models in 3D to date (n = 29, including many non-transformed and most currently available classic prostate cancer (PrCa cell lines. The purpose of this study was to analyze morphogenetic properties of PrCa models in 3D, to compare phenotypes, gene expression and metabolism between 2D and 3D cultures, and to evaluate their relevance for pre-clinical drug discovery, disease modeling and basic research. Primary and non-transformed prostate epithelial cells, but also several PrCa lines, formed well-differentiated round spheroids. These showed strong cell-cell contacts, epithelial polarization, a hollow lumen and were covered by a complete basal lamina (BL. Most PrCa lines, however, formed large, poorly differentiated spheroids, or aggressively invading structures. In PC-3 and PC-3M cells, well-differentiated spheroids formed, which were then spontaneously transformed into highly invasive cells. These cell lines may have previously undergone an epithelial-to-mesenchymal transition (EMT, which is temporarily suppressed in favor of epithelial maturation by signals from the extracellular matrix (ECM. The induction of lipid and steroid metabolism, epigenetic reprogramming, and ECM remodeling represents a general adaptation to 3D culture, regardless of transformation and phenotype. In contrast, PI3-Kinase, AKT, STAT/interferon and integrin signaling pathways were particularly activated in invasive cells. Specific small molecule inhibitors targeted against PI3-Kinase blocked invasive cell growth more effectively in 3D than in 2D monolayer culture, or the growth of normal cells. Our panel of cell models, spanning a wide spectrum of phenotypic
In January 1992, the Radiation Protection Research Action formed a panel of thyroid experts in order to evaluate the current situation concerning reported increased rates of thyroid cancer in children living in the neighbourhood of Chernobyl, where the reactor accident occurred on April 26 1986 and resulted in widespread radioactive contamination over large areas of Belarus, Russia, Ukraine. Studies of the Atom Bomb survivors in Japan have revealed that the incidence of leukemia starts to increase some five years after exposure. For Chernobyl accident health consequences are now becoming evident. Thyroid cancer has already been observed in children. Iodine 131 was seen to pose a specific hazard because it is taken up by the body and concentrated in the thyroid gland. At a dose of 5 Gy to the childhood thyroid about 4000 thyroid cancers per 100000 children exposed can be anticipated. An essential component of the verification of this observation is the study of the pathology of the lesions, which derived from four cell types: follicular cells, C cells, lymphoid cells and connective tumor cells. All distant metastases are lung metastases. Measures to be considered for the prevention of the development of thyroid cancer in a radiation-exposed population include correction of iodine deficiency by iodine prophylaxis and suppression of TSH. There are three methods of diagnosis: ultrasound imaging, thyroid scanning, fine needle aspiration performed by skilled personnel. For the therapy total or near-total thyroidectomy is regarded as the treatment of choice. Radioactive iodine can be used to treat lymph node and distant metastases which take up iodine after a total thyroidectomy. Thyroid hormone replacement should be carried out with TSH suppressive doses of L-Thyroxine. 45 refs., 1 annexe

Despite having achieved nationwide registry coverage in addition to substantial improvements in data on the epidemiology of cancer in Germany, the Centre for Cancer Registry Data continues to estimate national statistics on incidence, survival, and prevalence instead of calculating these directly from available data. The methods used for evaluations are based initially on estimates of registration completeness or, for survival analyses, an assessment of the quality of follow-up data. The completeness of incident case registration is estimated on the basis of the mortality/incidence procedure, which assumes a largely constant relationship between the mortality and incidence of a cancer type among people of the same age and sex across federal states. Inclusion criteria for consideration of registry data in national survival analyses are less than 15% of death certificate only (DCO) cases and plausible survival for patients with pancreatic cancer or metastatic lung cancer. Of the 477,300 incident cancer cases estimated for 2010, 429,900 were reported by the cancer registries (90%), and ten federal states contributed data to national survival estimates. PMID:24357167

Full Text Available The utilization of next-generation sequencing technology to interrogate multiple genes simultaneously is being utilized more frequently in hereditary cancer testing. While this has benefits of reducing cost and allowing clinicians to cast a wide net in the elucidation of their patient’s cancer, panel testing has the potential to reveal unexpected information. We report on a proband with pathogenic variants resulting in two different hereditary colon cancer syndromes.A 39-year-old male with a history of colon cancer, more than 20 colon polyps and a family history of colon cancer presented for genetic counseling. Testing with a 7-gene high-risk hereditary colon cancer panel identified a homozygous pathogenic variant, c.1187G>A (p.Gly396Asp in MUTYH, and a likely pathogenic duplication of exon 7 in MSH2. Since this test result, the proband’s mother was diagnosed with colon cancer; subsequent genetic testing confirmed she also carries the likely pathogenic duplication in the MSH2 gene.Although the cancer risk in individuals who carry multiple pathogenic variants has not been established for combined biallelic MUTYH-associated polyposis and Lynch syndrome, the identification of multiple pathogenic variants does allow for screening for cancers associated with both syndromes and has implications for cancer risk for family members. In particular, this has significant impact on those who test negative for a known familial pathogenic variant, yet could be still be at risk for cancer due to a second pathogenic variant in a family. More information is needed on the frequency of occurrence of multiple pathogenic variants, as well as the phenotypic spectrum when multiple pathogenic variants are present.

The Common Rule is a set of ethical principles that provide guidance on the management of human subjects taking part in biomedical and behavioral research in the United States. The elements of the Common Rule were initially developed in 1981 following a revision of the Declaration of Helsinki in 1975. Most academic facilities follow the Common Rule in the regulation of clinical trials research. Recently, the government has suggested a revision of the Common Rule to include more contemporary and streamlined oversight of clinical research. In this commentary, the leadership of the Society for Immunotherapy of Cancer (SITC) provides their opinion on this plan. While the Society recognizes the considerable contribution of clinical research in supporting progress in tumor immunotherapy and supports the need for revisions to the Common Rule, there is also some concern over certain elements which may restrict access to biospecimens and clinical data at a time when high throughput technologies, computational biology and assay standardization is allowing major advances in understanding cancer biology and providing potential predictive biomarkers of immunotherapy response. The Society values its professional commitment to patients for improving clinical outcomes with tumor immunotherapy and supports continued discussion with all stakeholders before implementing changes to the Common Rule in order to ensure maximal patient protections while promoting continued clinical research at this historic time in cancer research.

Selection of the optimal surgical and interventional therapies for advanced colorectal cancer liver metastases (CRLM) requires multidisciplinary discussion of treatment strategies early in the trajectory of the individual patient's care. This paper reports on expert consensus on locoregional and interventional therapies for the treatment of advanced CRLM. Resection remains the reference treatment for patients with bilateral CRLM and synchronous presentation of primary and metastatic cancer. Patients with oligonodular bilateral CRLM may be candidates for one-stage multiple segmentectomies; two-stage resection with or without portal vein embolization may allow complete resection in patients with more advanced disease. After downsizing with preoperative systemic and/or regional therapy, curative-intent hepatectomy requires resection of all initial and currently known sites of disease; debulking procedures are not recommended. Many patients with synchronous primary disease and CRLM can safely undergo simultaneous resection of all disease. Staged resections should be considered for patients in whom the volume of the future liver remnant is anticipated to be marginal or inadequate, who have significant medical comorbid condition(s), or in whom extensive resections are required for the primary cancer and/or CRLM. Priority for liver-first or primary-first resection should depend on primary tumour-related symptoms or concern for the progression of marginally resectable CRLM during treatment of the primary disease. Chemotherapy delivered by hepatic arterial infusion represents a valid option in patients with liver-only disease, although it is best delivered in experienced centres. Ablation strategies are not recommended as first-line treatments for resectable CRLM alone or in combination with resection because of high local failure rates and limitations related to tumour size, multiplicity and intrahepatic location.

Full Text Available Abstract Background Colorectal cancer (CRC screening is key to CRC prevention and mortality reduction, but patient compliance with CRC screening is low. We previously reported a blood-based test for CRC that utilizes a seven-gene panel of biomarkers. The test is currently utilized clinically in North America for CRC risk stratification in the average-risk North American population in order to improve screening compliance and to enhance clinical decision making. Methods In this study, conducted in Malaysia, we evaluated the seven-gene biomarker panel validated in a North American population using blood samples collected from local patients. The panel employs quantitative RT-PCR (qRT-PCR to analyze gene expression of the seven biomarkers (ANXA3, CLEC4D, TNFAIP6, LMNB1, PRRG4, VNN1 and IL2RB that are differentially expressed in CRC patients as compared with controls. Blood samples from 210 patients (99 CRC and 111 controls were collected, and total blood RNA was isolated and subjected to quantitative RT-PCR and data analysis. Results The logistic regression analysis of seven-gene panel has an area under the curve (AUC of 0.76 (95% confidence interval: 0.70 to 0.82, 77% specificity, 61% sensitivity and 70% accuracy, comparable to the data obtained from the North American investigation of the same biomarker panel. Conclusions Our results independently confirm the results of the study conducted in North America and demonstrate the ability of the seven biomarker panel to discriminate CRC from controls in blood samples drawn from a Malaysian population.

Based on our 2013-article, ”Does Deployment to War Affect Soldiers' Public Service Motivation – A Panel Study of Soldiers Before and After their Service in Afghanistan”, we present Panel Analysis as a methodological discipline. Panels consist of multiple units of analysis, observed at two or more...... in research settings where it is not possible to distribute units of analysis randomly or where the independent variables cannot be manipulated. The greatest disadvantage in regard to using panel studies is that data may be difficult to obtain. This is most clearly vivid in regard to the use of panel surveys...

Radiotherapy alone or in combination with chemotherapy and/or surgery is a well-known radical treatment for head and neck cancer patients. Nevertheless acute side effects (such as moist desquamation, skin erythema, loss of taste, mucositis etc.) and in particular late toxicities (osteoradionecrosis, xerostomia, trismus, radiation caries etc.) are often debilitating and underestimated. A multidisciplinary group of head and neck cancer specialists from Italy met in Milan with the aim of reaching a consensus on a clinical definition and management of these toxicities. The Delphi Appropriateness method was used for this consensus and external experts evaluated the conclusions. The paper contains 20 clusters of statements about the clinical definition and management of stomatological issues that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecrosis (10 clusters of statements), whereas this second part deals with trismus and xerostomia (10 clusters of statements).

Full Text Available Abstract Background Ki67 is widely used in order to distinguish the “A” and “B” subtypes of luminal-type breast cancer. This study aimed to validate the prognostic value of adding p53 to Ki67 for characterizing luminal-type breast cancer. Methods Immunostaining for Ki67, p53, and the molecular markers HER2, CK5/6, CK14, EGFR, FOXA1, GATA3, and P-cadherin was examined hormone receptor (HR-positive cancer tissues from 150 patients. The prognostic value of an immunohistochemical panel comprising Ki67 and p53 was compared with that of the single Ki67 labeling index (LI, and uni- and multivariate analyses were performed. Results Division of the patients based on the immunohistochemistry results into favorable- (low Ki67 LI, p53-negative and unfavorable- (high Ki67 LI and/or p53-positive phenotype groups yielded distinctly different Kaplan-Meier's curves of both disease-free (PP=0.0007. These differences were much more distinct than those between the corresponding low Ki67 LI vs. high Ki67LI curves. While the prognostic values of the other molecular markers were not significant, combined Ki67-p53 status was an independent prognostic factor by multivariate analysis. Conclusion These data indicate that an immunohistochemical panel comprising Ki67 and p53 is a practical tool for management of patients with HR-positive breast cancer.
The presence of circulating tumor cells (CTC) in the peripheral blood of cancer patients has been described for various solid tumors and their clinical relevance has been shown. CTC detection based on the analysis of epithelial antigens might be hampered by the genetic heterogeneity of the primary tumor and loss of epithelial antigens. Therefore, we aimed to identify new gene markers for the PCR-based detection of CTC in female cancer patients. Gene expression of 38 cancer cell lines (breast, ovarian, cervical and endometrial) and of 10 peripheral blood mononuclear cell (PBMC) samples from healthy female donors was measured using microarray technology (Applied Biosystems). Differentially expressed genes were identified using the maxT test and the 50% one-sided trimmed maxT-test. Confirmatory RT-qPCR was performed for 380 gene targets using the AB TaqMan® Low Density Arrays. Then, 93 gene targets were analyzed using the same RT-qPCR platform in tumor tissues of 126 patients with primary breast, ovarian or endometrial cancer. Finally, blood samples from 26 healthy women and from 125 patients (primary breast, ovarian, cervical, or endometrial cancer, and advanced breast cancer) were analyzed following OncoQuick enrichment and RNA pre-amplification. Likewise, hMAM and EpCAM gene expression was analyzed in the blood of breast and ovarian cancer patients. For each gene, a cut-off threshold value was set at three standard deviations from the mean expression level of the healthy controls to identify potential markers for CTC detection. Six genes were over-expressed in blood samples from 81% of patients with advanced and 29% of patients with primary breast cancer. EpCAM gene expression was detected in 19% and 5% of patients, respectively, whereas hMAM gene expression was observed in the advanced group (39%) only. Multimarker analysis using the new six gene panel positively identified 44% of the cervical, 64% of the endometrial and 19% of the ovarian cancer patients. The

Oncologists have a critical opportunity to utilize risk assessment and cancer prevention strategies to interrupt the initiation or progression of cancer in cancer survivors and individuals at high risk of developing cancer. Expanding knowledge about the natural history and prognosis of cancers positions oncologists to advise patients regarding the risk of second malignancies and treatment-related cancers. In addition, as recognized experts in the full spectrum of cancer care, oncologists are ...

Radiotherapy alone or in combination with chemotherapy and/or surgery is the typical treatment for head and neck cancer patients. Acute side effects (such as oral mucositis, dermatitis, salivary changes, taste alterations, etc.), and late toxicities in particular (such as osteo-radionecrosis, hypo-salivation and xerostomia, trismus, radiation caries etc.), are often debilitating. These effects tend to be underestimated and insufficiently addressed in the medical community. A multidisciplinary group of head and neck cancer specialists met in Milan with the aim of reaching a consensus on clinical definitions and management of these toxicities. The Delphi Appropriateness method was used for developing the consensus, and external experts evaluated the conclusions. This paper contains 10 clusters of statements about the clinical definitions and management of head and neck cancer treatment sequels (dental pathologies and osteo-radionecroses) that reached consensus, and offers a review of the literature about these topics. The review was split into two parts: the first part dealt with dental pathologies and osteo-radionecroses (10 clusters of statements), whereas this second part deals with trismus and xerostomia.

41 reported diagnoses of cancer (EKN 2010b). The EKN established in (EKN 2010b) that after correction for multiple testing the results for all the municipalities of the district of Wolfenbuettel other than the Samtgemeinde Asse were not significant. The only significant findings were the results for leukaemia and thyroid cancer in the Samtgemeinde Asse. The Federal Ministry for the Environment, Nature Conservation and Nuclear Safety (BMU) wrote to the Commission on Radiological Protection (SSK) on 20 December 2010 requesting a statement on the results of the EKN's analysis of the incidence of cancer in the Samtgemeinde Asse. In particular, the statement needed to examine the statistical methods used and answer the following questions: Is there radiobiological information that could plausibly explain the findings? How can the findings be explained?.

The early detection of breast cancer, the most common malignant tumor disease in women worldwide, relies on mammography and self breast examination. Here we evaluated the concentration of nicotinamide phosphoribosyltransferase (NAMPT), vascular endothelial growth factor (VEGF) and human epidermal growth factor receptor-2 (HER2) in serum and their expression in breast tissues associated with the clinicopathological features of patients with benign and malignant breast tumors. The immunohistochemical analysis showed that NAMPT, VEGF and HER2 proteins were overexpressed in breast tumors. The highest expression was observed in malignant tumors, low in benign tumors and negative in the adjacent normal tissue, indicating that the triplets may be progression markers and correlated with each other. The detection rate of NAMPT, VEGF and HER2 alone in tissue was 54.17, 64.58 and 60.42%, respectively, and was increased to about 79% in double combination and to 90% in triple combination. The basal levels of serum NAMPT, VEGF and HER2 in healthy controls were 94.90±4.24 pg/ml, 87.02±2.41 pg/ml and 1.12±0.04 ng/ml, respectively, measured by ELISA and found to be increased by 6.64-, 1.76- and 2.52-fold, respectively, in patients with malignant breast tumor. These elevated serum levels of NAMPT, VEGF and HER2 in patients were decreased after tumor removal, suggesting that these molecules are the indicators of treatment efficacy. The combined measurement of these triplets together may improve the sensitivity of breast cancer diagnosis and may potentially be used as a testing panel for the detection of malignant tumors, the assessment of treatment effectiveness and the monitoring of the disease progression in patients with breast cancer. Thus, we propose that the biomarker triplet NAMPT/VEGF/HER2 can be used as a de novo detection panel for the diagnosis and prognosis of human breast cancer. PMID:26531769

Although omic-based discovery approaches can provide powerful tools for biomarker identification, several reservations have been raised regarding the clinical applicability of gene expression studies, such as their prohibitive cost. However, the limited availability of antibodies is a key barrier to the development of a lower cost alternative, namely a discrete collection of immunohistochemistry (IHC)-based biomarkers. The aim of this study was to use a systematic approach to generate and screen affinity-purified, mono-specific antibodies targeting progression-related biomarkers, with a view towards developing a clinically applicable IHC-based prognostic biomarker panel for breast cancer. We examined both in-house and publicly available breast cancer DNA microarray datasets relating to invasion and metastasis, thus identifying a cohort of candidate progression-associated biomarkers. Of these, 18 antibodies were released for extended analysis. Validated antibodies were screened against a tissue microarray (TMA) constructed from a cohort of consecutive breast cancer cases (n = 512) to test the immunohistochemical surrogate signature. Antibody screening revealed 3 candidate prognostic markers: the cell cycle regulator, Anillin (ANLN); the mitogen-activated protein kinase, PDZ-Binding Kinase (PBK); and the estrogen response gene, PDZ-Domain Containing 1 (PDZK1). Increased expression of ANLN and PBK was associated with poor prognosis, whilst increased expression of PDZK1 was associated with good prognosis. A 3-marker signature comprised of high PBK, high ANLN and low PDZK1 expression was associated with decreased recurrence-free survival (p < 0.001) and breast cancer-specific survival (BCSS) (p < 0.001). This novel signature was associated with high tumour grade (p < 0.001), positive nodal status (p = 0.029), ER-negativity (p = 0.006), Her2-positivity (p = 0.036) and high Ki67 status (p < 0.001). However, multivariate Cox regression demonstrated that the signature was
Purpose: The ASTRO Consensus Panel on PSA After Radiation Therapy recently recommended a definition of biochemical failure (BF) following treatment of prostate cancer with radiation therapy. We reviewed our institution's experience treating patients with external beam irradiation (RT) to determine if the Consensus Panel definition correlates with clinical distant metastases free survival (DMFS), disease free survival (DFS), cause specific survival (CSS), and local control (LC) rates for a large group of patients from the PSA era. Methods And Materials: Between 1/1/87 and 12/31/92, 653 patients with clinically localized prostate cancer received external beam irradiation (RT) using localized prostate fields at William Beaumont Hospital. Of these patients, 568 had a minimum follow-up of 2 years and constitute the study population. The median pre-treatment PSA and Gleason score was 11 ng/ml and 6, respectively. The median dose to the prostate using megavoltage RT was 66.6 Gy (range: 60-70.4 Gy) using a four field or arc technique. No patient received hormonal therapy either prior to, during, or after radiotherapy unless local or distant failure was documented. Pre-treatment and post-treatment serum PSA levels were recorded. Biochemical failure was defined as three consecutive increases in post-treatment PSA after achieving a nadir. Biochemical failure was recorded as the time midway between the nadir and first increase in PSA. Five year actuarial rates of DMFS, DFS, CSS, and LC were calculated for patients who were biochemically controlled (BC) versus those who failed biochemically. Results: Median follow-up was 56 months (range: 24-118 months). The overall 5 year actuarial rates of DMFS, DFS, CSS, and LC were significantly better in patients who were biochemically controlled versus those who were not (p< 0.001). The median time to DM within the BF group was 21 months (range: 2-112 months). When stratifying by pre-treatment PSA, Gleason score, and T stage, these

Mutation in BRCA1/BRCA2 genes accounts for 20% of familial breast cancers, 5% to 10% of which may be due to other less penetrant genes which are still incompletely studied. Herein, a four-gene panel was used to examine the prevalence of BRCA1, BRCA2, TP53, and PTEN in hereditary breast and ovarian cancers in Southern Chinese population. In this cohort, 948 high-risk breast and/or ovarian patients were recruited for genetic screening by next-generation sequencing (NGS). The performance of our NGS pipeline was evaluated with 80 Sanger-validated known mutations and eight negative cases. With appropriate bioinformatics analysis pipeline, the detection sensitivity of NGS is comparable with Sanger sequencing. The prevalence of BRCA1/BRCA2 germline mutations was 9.4% in our Chinese cohort, of which 48.8% of the mutations arose from hotspot mutations. With the use of a tailor-made algorithm, HomopolymerQZ, more mutations were detected compared with single mutation detection algorithm. The frequencies of PTEN and TP53 were 0.21% and 0.53%, respectively, in the Southern Chinese patients with breast and/or ovarian cancers. High-throughput NGS approach allows the incorporation of control cohort that provides an ethnicity-specific data for polymorphic variants. Our data suggest that hotspot mutations screening such as SNaPshot could be an effective preliminary screening alternative adopted in a standard clinical laboratory without NGS setup. PMID:27157322
We studied the performance of a dual-panel positron emission tomography (PET) camera dedicated to breast cancer imaging using Monte Carlo simulation. The PET camera under development has two 10x15 cm2 plates that are constructed from arrays of 1x1x3 mm3 LSO crystals coupled to novel ultra-thin (3 intrinsic spatial resolution, 3, 2x2x10 mm3, 3x3x30 mm3, and 4x4x20 mm3 LSO crystal resolutions and different panel separations. Images were reconstructed by focal plane tomography with attenuation and normalization corrections applied. Simulation results indicate that with an activity concentration ratio of tumor:breast:heart:torso of 10:1:10:1 and 30 s of acquisition time, only the dual-plate PET camera comprising 1x1x3 mm3 crystals could resolve 2.5 mm diameter spheres with an average peak-to-valley ratio of 1.3
With the ongoing need to improve therapy for non–small cell lung cancer (NSCLC) there has been increasing interest in developing reliable preclinical models to test novel therapeutics. Patient-derived tumor xenografts (PDX) are considered to be interesting candidates. However, the establishment of such model systems requires highly specialized research facilities and introduces logistic challenges. We aimed to establish an extensive well-characterized panel of NSCLC xenograft models in the context of a long-distance research network after careful control of the preanalytical steps. One hundred fresh surgically resected NSCLC specimens were shipped in survival medium at room temperature from a hospital-integrated biobank to animal facilities. Within 24 h post-surgery, tumor fragments were subcutaneously xenografted into immunodeficient mice. PDX characterization was performed by histopathological, immunohistochemical, aCGH and next-generation sequencing approaches. For this model system, the tumor take rate was 35%, with higher rates for squamous carcinoma (60%) than for adenocarcinoma (13%). Patients for whom PDX tumors were obtained had a significantly shorter disease-free survival (DFS) compared to patients for whom no PDX tumors (P = 0.039) were obtained. We established a large panel of PDX NSCLC models with a high frequency of mutations (29%) in EGFR, KRAS, NRAS, MEK1, BRAF, PTEN, and PI3KCA genes and with gene amplification (20%) of c-MET and FGFR1. This new patient-derived NSCLC xenograft collection, established regardless of the considerable time required and the distance between the clinic and the animal facilities, recapitulated the histopathology and molecular diversity of NSCLC and provides stable and reliable preclinical models for human lung cancer research

The variability of radiation responses in ovarian tumors and tumor-derived cell lines is poorly understood. Since both DNA repair capacity and p53 status can significantly alter radiation sensitivity, we evaluated these factors along with radiation sensitivity in a panel of sporadic human ovarian carcinoma cell lines. We observed a gradation of radiation sensitivity among these sixteen lines, with a five-fold difference in the LD50 between the most radiosensitive and the most radioresistant cells. The DNA-dependent protein kinase (DNA-PK) is essential for the repair of radiation induced DNA double-strand breaks in human somatic cells. Therefore, we measured gene copy number, expression levels, protein abundance, genomic copy and kinase activity for DNA-PK in all of our cell lines. While there were detectable differences in DNA-PK between the cell lines, there was no clear correlation with any of these differences and radiation sensitivity. In contrast, p53 function as determined by two independent methods, correlated well with radiation sensitivity, indicating p53 mutant ovarian cancer cells are typically radioresistant relative to p53 wild-type lines. These data suggest that the activity of regulatory molecules such as p53 may be better indicators of radiation sensitivity than DNA repair enzymes such as DNAPK in ovarian cancer.

Full Text Available Abstract Background Hereditary non-polyposis colon cancer (HNPCC is an autosomal dominant syndrome predisposing to the early development of various cancers including those of colon, rectum, endometrium, ovarium, small bowel, stomach and urinary tract. HNPCC is caused by germline mutations in the DNA mismatch repair genes, mostly hMSH2 or hMLH1. In this study, we report the analysis for genetic counseling of three first-degree relatives (the mother and two sisters of a male who died of colorectal adenocarcinoma at the age of 23. The family fulfilled strict Amsterdam-I criteria (AC-I with the presence of extracolonic tumors in the extended pedigree. We overcame the difficulty of having a proband post-mortem non-tumor tissue sample for MSI testing by studying the alleles carried by his progenitors. Methods Tumor MSI testing is described as initial screening in both primary and metastasis tumor tissue blocks, using the reference panel of 5 microsatellite markers standardized by the National Cancer Institute (NCI for the screening of HNPCC (BAT-25, BAT-26, D2S123, D5S346 and D17S250. Subsequent mutation analysis of the hMLH1 and hMSH2 genes was performed. Results Three of five microsatellite markers (BAT-25, BAT-26 and D5S346 presented different alleles in the proband's tumor as compared to those inherited from his parents. The tumor was classified as high frequency microsatellite instability (MSI-H. We identified in the HNPCC family a novel germline missense (c.1864C>A mutation in exon 12 of hMSH2 gene, leading to a proline 622 to threonine (p.Pro622Thr amino acid substitution. Conclusion This approach allowed us to establish the tumor MSI status using the NCI recommended panel in the absence of proband's non-tumor tissue and before sequencing the obligate carrier. According to the Human Gene Mutation Database (HGMD and the International Society for Gastrointestinal Hereditary Tumors (InSiGHT Database this is the first report of this mutation.

Full Text Available Simvastatin and lovastatin are statins traditionally used for lowering serum cholesterol levels. However, there exists evidence indicating their potential chemotherapeutic characteristics in cancer. In this study, we used bioinformatic analysis of publicly available data in order to systematically identify the genes involved in resistance to cytotoxic effects of these two drugs in the NCI60 cell line panel. We used the pharmacological data available for all the NCI60 cell lines to classify simvastatin or lovastatin resistant and sensitive cell lines, respectively. Next, we performed whole-genome single marker case-control association tests for the lovastatin and simvastatin resistant and sensitive cells using their publicly available Affymetrix 125K SNP genomic data. The results were then evaluated using RNAi methodology. After correction of the p-values for multiple testing using False Discovery Rate, our results identified three genes (NRP1, COL13A1, MRPS31 and six genes (EAF2, ANK2, AKAP7, STEAP2, LPIN2, PARVB associated with resistance to simvastatin and lovastatin, respectively. Functional validation using RNAi confirmed that silencing of EAF2 expression modulated the response of HCT-116 colon cancer cells to both statins. In summary, we have successfully utilized the publicly available data on the NCI60 cell lines to perform whole-genome association studies for simvastatin and lovastatin. Our results indicated genes involved in the cellular response to these statins and siRNA studies confirmed the role of the EAF2 in response to these drugs in HCT-116 colon cancer cells.
Purpose: We reviewed our institution's experience treating patients with external beam irradiation (RT) to determine if the ASTRO Consensus Panel definition of biochemical failure (BF) following radiation therapy correlates with clinical distant metastases free survival (DMFS), disease-free survival (DFS), cause-specific survival (CSS), and local control (LC). Methods and Materials: Between 1/1/87 and 12/31/92, 568 patients with clinically localized prostate cancer received external beam irradiation (RT) using localized prostate fields at William Beaumont Hospital (median total dose 66.6 Gy; range: 60-70.4 Gy). Biochemical failure was defined as three consecutive increases in post-treatment prostate specific antigen (PSA) after achieving a nadir. Biochemical failure was recorded as the time midway between the nadir and the first rising PSA. Five-year actuarial rates of clinical DMFS, DFS, CSS, and LC were calculated for patients who were biochemically controlled (BC) versus those who failed biochemically. Median follow-up was 56 months (range: 24-118 months). Results: Five-year actuarial rates of DMFS, DFS, CSS, and LC were significantly greater in patients who were biochemically controlled versus those who were not (p < 0.001). In patients who were BC, the 5-year actuarial rates of DMFS, DFS, CSS, and LC were 99%, 99%, 98%, and 99% respectively. For patients who failed biochemically, the 5-year actuarial rates of DMFS, DFS, CSS, and LC were 74%, 64%, 89%, and 86% respectively. When stratifying by pretreatment PSA, Gleason score, and T stage these differences remained significant for DMFS, DFS, and CSS. The Cox proportional hazards model demonstrated that BC was the single most important predictor of clinical outcome for DMFS, DFS, CSS, and LC. Pretreatment PSA and Gleason score were also independent predictors of outcome for DMFS and DFS. Conclusions: The ASTRO Consensus Panel definition of BF following radiation therapy correlates well with clinical DMFS, DFS

Radiation dose escalation has been shown to improve local control and survival in patients with non-small cell lung cancer in some studies, but randomized data have not supported this premise, possibly owing to adverse effects. Because of the physical characteristics of the Bragg peak, proton therapy (PT) delivers minimal exit dose distal to the target volume, resulting in better sparing of normal tissues in comparison to photon-based radiation therapy. This is particularly important for lung cancer given the proximity of the lung, heart, esophagus, major airways, large blood vessels, and spinal cord. However, PT is associated with more uncertainty because of the finite range of the proton beam and motion for thoracic cancers. PT is more costly than traditional photon therapy but may reduce side effects and toxicity-related hospitalization, which has its own associated cost. The cost of PT is decreasing over time because of reduced prices for the building, machine, maintenance, and overhead, as well as newer, shorter treatment programs. PT is improving rapidly as more research is performed particularly with the implementation of 4-dimensional computed tomography-based motion management and intensity modulated PT. Given these controversies, there is much debate in the oncology community about which patients with lung cancer benefit significantly from PT. The Particle Therapy Co-operative Group (PTCOG) Thoracic Subcommittee task group intends to address the issues of PT indications, advantages and limitations, cost-effectiveness, technology improvement, clinical trials, and future research directions. This consensus report can be used to guide clinical practice and indications for PT, insurance approval, and clinical or translational research directions. PMID:27084663

Full Text Available NCIC Clinical Trials Group PA.3 was a randomized control trial that demonstrated improved overall survival (OS in patients receiving erlotinib in addition to gemcitabine for locally advanced or metastatic pancreatic cancer. Prior to therapy, patients had plasma samples drawn for future study. We sought to identify biomarkers within these samples.Using the proximity ligation assay (PLA, a probe panel was built from commercially available antibodies for 35 key proteins selected from a global genetic analysis of pancreatic cancers, and used to quantify protein levels in 20 uL of patient plasma. To determine if any of these proteins levels independently associated with OS, univariate and mulitbaraible Cox models were used. In addition, we examined the associations between biomarker expression and disease stage at diagnosis using Fisher's exact test. The correlation between Erlotinib sensitivity and each biomarkers was assessed using a test of interaction between treatment and biomarker.Of the 569 eligible patients, 480 had samples available for study. Samples were randomly allocated into training (251 and validation sets (229. Among all patients, elevated levels of interleukin-8 (IL-8, carcinoembryonic antigen (CEA, hypoxia-inducible factor 1-alpha (HIF-1 alpha, and interleukin-6 were independently associated with lower OS, while IL-8, CEA, platelet-derived growth factor receptor alpha and mucin-1 were associated with metastatic disease. Patients with elevated levels of receptor tyrosine-protein kinase erbB-2 (HER2 expression had improved OS when treated with erlotinib compared to placebo. In conclusion, PLA is a powerful tool for identifying biomarkers from archived, small volume serum samples. These data may be useful to stratify patient outcomes regardless of therapeutic intervention.ClinicalTrials.gov NCT00040183.

Chemotherapy-induced nausea and vomiting (CINV) is a common, but now often overlooked side effect of cancer treatment, and one that can be largely prevented through the implementation of international evidence-based guidelines. The European CINV Forum, comprising nurses from France, Germany, Portugal, Spain and the UK, discussed the use of CINV preventive strategies in routine practice, and the factors that affect optimal delivery of antiemetic therapies. Based on these discussions, they developed a series of recommendations for optimal, evidence-based management of CINV. These state that all patients receiving chemotherapy should undergo full assessment of their risk of CINV and receive appropriate prophylactic treatment based on guidelines from the Multinational Association of Supportive Care in Cancer (MASCC) and the National Comprehensive Cancer Network (NCCN), which were both updated in 2011. Other recommendations, aimed at raising awareness of CINV and its management, include timely updates of relevant local practice guidelines and protocols, translation of the MASCC and NCCN guidelines into all European languages and their dissemination through accessible articles in nursing journals and newsletters and via nursing conferences and study days, improved training for nurses on CINV, collaboration between the European Oncology Nursing Society and national nursing organisations to promote consistent practice, the development of a CINV toolkit, information provision for patients, local audits of CINV management, and a survey of CINV management between and within European countries.

Selective phosphoinositide 3-kinase (PI3K)/AKT/mTOR inhibitors are currently under evaluation in clinical studies. To identify tumor types that are sensitive to PI3K pathway inhibitors we screened compounds targeting PI3Kα/δ (AZD8835), PI3Kβ/δ (AZD8186), AKT (AZD5363) and mTORC1/2 (AZD2014) against a cancer cell line panel (971 cell lines). There was an enrichment of hematological malignancies that were sensitive to AKT and mTOR inhibition, with the greatest degree of sensitivity observed in T-cell acute lymphoblastic leukemia (T-ALL). We found that all NOTCH mutant T-ALL cell lines were sensitive to AKT and mTORC1/2 inhibitors, with only partial sensitivity to agents that target the PI3K α, β or δ isoforms. Induction of apoptosis only occurred following AKTi treatment in cell lines with PTEN protein loss and high levels of active AKT. In summary, we have demonstrated that T-ALL cell lines show differential sensitivity to inhibition at different nodes in the PI3K/AKT/mTOR pathway and inhibiting AKT or mTOR may have a therapeutic benefit in this disease setting.

Full Text Available Protocols for activity aiming at early diagnosis and treatment of inherited breast or breast-ovarian cancer have been reported. Available reports on outcome of such programmes are considered here. It is concluded that the ongoing activities should continue with minor modifications. Direct evidence of a survival benefit from breast and ovarian screening is not yet available. On the basis of expert opinion and preliminary results from intervention programmes indicating good detection rates for early breast cancers and 5-year survival concordant with early diagnosis, we propose that women at high risk for inherited breast cancer be offered genetic counselling, education in ‘breast awareness’ and annual mammography and clinical expert examination from around 30 years of age. Mammography every second year may be sufficient from 60 years on. BRCA1 mutation carriers may benefit from more frequent examinations and cancer risk may be reduced by oophorectomy before 40–50 years of age. We strongly advocate that all activities should be organized as multicentre studies subjected to continuous evaluation to measure the effects of the interventions on long-term mortality, to match management options more precisely to individual risks and to prepare the ground for studies on chemoprevention.

As an international medical society dedicated to cancer prevention, the American Society of Clinical Oncology (ASCO) advocates a fundamental reform of United States and international policy toward addictive tobacco products. ASCO's goal is the immediate reduction of tobacco use and ultimate achievement of a tobacco-free world. The centerpiece of ASCO's policy is the recommendation for an independent commission to study the tobacco problem in all of its dimensions: social, medical, legal, and economic (both domestically and globally). The commission membership should include broad-based representation and expertise on tobacco issues. In ASCO's view, tobacco control efforts to date have been less than successful because they are too fragmented and incremental, leaving many important issues unaddressed. A more comprehensive solution could flow from this study, including input from a variety of government agencies involved with public health, agriculture, First Amendment and other legal considerations, and international trade. The study, within defined time limits, should culminate in a report that outlines a strategy for achieving immediate reduction of tobacco use and ultimate achievement of a tobacco-free world, including explicit plans and a timetable for implementation. Although this comprehensive approach to tobacco control will take many years to implement even under the best of circumstances, there are certain measures that could be undertaken immediately with meaningful impact on tobacco usage. These include: Increasing efforts to discourage tobacco use, particularly among the young Raising federal excise taxes by at least $2 per pack and encouraging states to consider tobacco taxes as a first resort in revenue enhancement Ensuring that tobacco settlement funds be devoted only to health-related projects, including medical treatment, biomedical research, and tobacco prevention efforts Requiring disclosure of all ingredients in tobacco products Comprehensively

The Evolving Role of Nivolumab in Non-Small-Cell Lung Cancer for Second-Line Treatment: A New Cornerstone for Our Treatment Algorithms. Results From an International Experts Panel Meeting of the Italian Association of Thoracic Oncology.
Gridelli, Cesare; Besse, Benjamin; Brahmer, Julie Renee; Crinò, Lucio; Felip, Enriqueta; de Marinis, Filippo
Lung cancer is the leading cause of death from cancer worldwide that currently has only a few available treatment options in patients with no driver mutations. The therapeutic options for patients with non-small-cell lung cancer (NSCLC) who progress after first-line chemotherapy have been limited from a long time. Docetaxel has remained a cornerstone of second-line treatment for more than 20 years, but it is associated with an unfavorable safety profile. Recently, the results from immunotherapy treatment with anti-PD1 and PD-L1 inhibitors has changed our current knowledge base and increased therapeutic options for patients with NSCLC in the second-line setting. The results of 2 randomized phase III trials assessing nivolumab in lung cancer, Check-Mate-017 and Check-Mate-057, have deeply changed our current clinical practice and raised several discussion points. This paper explores the recent findings about nivolumab for the treatment of NSCLC in the second-line setting by analyzing recent trial findings and discussing their implications in clinical practice and future directions. The paper also summarizes the conclusions from an International Experts Panel Meeting of the Italian Association of Thoracic Oncology. PMID:26908078
In the summer of 2013 the International Committee on Future Accelerators (ICFA) established a Neutrino Panel with the mandate: "To promote international cooperation in the development of the accelerator-based neutrino-oscillation program and to promote international collaboration in the development of a neutrino factory as a future intense source of neutrinos for particle physics experiments." In its first year the Panel organised a series of regional Town Meetings to collect input from the community and to receive reports from the regional planning exercises. The Panel distilled its findings and presented them in a report to ICFA . In this contribution the formation and composition of the Panel are presented together with a summary of the Panel's findings from the three Regional Town Meetings. The Panel's initial conclusions are then articulated and the steps that the Panel seeks to take are outlined.

The emergence of large-scale freeform shapes in architecture poses big challenges to the fabrication of such structures. A key problem is the approximation of the design surface by a union of patches, socalled panels, that can be manufactured with a selected technology at reasonable cost, while meeting the design intent and achieving the desired aesthetic quality of panel layout and surface smoothness. The production of curved panels is mostly based on molds. Since the cost of mold fabrication often dominates the panel cost, there is strong incentive to use the same mold for multiple panels. We cast the major practical requirements for architectural surface paneling, including mold reuse, into a global optimization framework that interleaves discrete and continuous optimization steps to minimize production cost while meeting user-specified quality constraints. The search space for optimization is mainly generated through controlled deviation from the design surface and tolerances on positional and normal continuity between neighboring panels. A novel 6-dimensional metric space allows us to quickly compute approximate inter-panel distances, which dramatically improves the performance of the optimization and enables the handling of complex arrangements with thousands of panels. The practical relevance of our system is demonstrated by paneling solutions for real, cutting-edge architectural freeform design projects. © 2010 ACM.

The paper describes the procedures of thermal mechanical tests carried out at the NASA Dryden Flight Research Facility on two tianium honeycomb wing panels bonded using liquid interface diffusion (LID) technique, and presents the results of these tests. The 58.4 cm square panels consisted of two 0.152-cm-thick Ti 6-2-4-2 face sheets LID-bonded to a 1.9-cm-thick honeycomb core, with bearing plates fastened to the perimeter of the upper and the lower panel surfaces. The panels were instrumented with sensors for measuring surface temperature, strain, and deflections to 315 C and 482 C. Thermal stress levels representative of those encountered during aerodynamic heating were produced by heating the upper panel surface and restraining all four edges. After more than 100 thermal cycles from room temperature to 315 C and 50 cycles from room temperature to 482 C, no significant structural degradation was detected in the panels.

Chemotherapy-induced diarrhea (cid) is a common side effect of cancer treatment and can cause significant morbidity and mortality. Diarrhea is frequently severe enough to require a dose reduction of, a delay in, or a discontinuation of chemotherapy. Diarrhea-associated mortality has been reported to be as high as 3.5% in clinical trials of irinotecan and bolus 5-fluorouracil in colorectal cancer. The frequency of cid and its impact on patient management are frequently under-recognized in clin...
Breast cancer screening in the era of density notification legislation: summary of 2014 Massachusetts experience and suggestion of an evidence-based management algorithm by multi-disciplinary expert panel.

Stemming from breast density notification legislation in Massachusetts effective 2015, we sought to develop a collaborative evidence-based approach to density notification that could be used by practitioners across the state. Our goal was to develop an evidence-based consensus management algorithm to help patients and health care providers follow best practices to implement a coordinated, evidence-based, cost-effective, sustainable practice and to standardize care in recommendations for supplemental screening. We formed the Massachusetts Breast Risk Education and Assessment Task Force (MA-BREAST) a multi-institutional, multi-disciplinary panel of expert radiologists, surgeons, primary care physicians, and oncologists to develop a collaborative approach to density notification legislation. Using evidence-based data from the Institute for Clinical and Economic Review, the Cochrane review, National Comprehensive Cancer Network guidelines, American Cancer Society recommendations, and American College of Radiology appropriateness criteria, the group collaboratively developed an evidence-based best-practices algorithm. The expert consensus algorithm uses breast density as one element in the risk stratification to determine the need for supplemental screening. Women with dense breasts and otherwise low risk (20% lifetime) should consider supplemental screening MRI in addition to routine mammography regardless of breast density. We report the development of the multi-disciplinary collaborative approach to density notification. We propose a risk stratification algorithm to assess personal level of risk to determine the need for supplemental screening for an individual woman. PMID:26290416

Purpose: To develop contouring guidelines to be used in the Radiation Therapy Oncology Group protocol 0848, a Phase III randomized trial evaluating the benefit of adjuvant chemoradiation in patients with resected head of pancreas cancer. Methods and Materials: A consensus committee of six radiation oncologists with expertise in gastrointestinal radiotherapy developed stepwise contouring guidelines and an atlas for the delineation of the clinical target volume (CTV) in the postoperative treatment of pancreas cancer, based on identifiable regions of interest and margin expansions. Areas at risk for subclinical disease to be included in the CTV were defined, including nodal regions, anastomoses, and the preoperative primary tumor location. Regions of interest that could be reproducibly contoured on postoperative imaging after a pancreaticoduodenectomy were identified. Standardized expansion margins to encompass areas at risk were developed after multiple iterations to determine the optimal margin expansions. Results: New contouring recommendations based on CT anatomy were established. Written guidelines for the delineation of the postoperative CTV and normal tissues, as well as a Web-based atlas, were developed. Conclusions: The postoperative abdomen has been a difficult area for effective radiotherapy. These new guidelines will help physicians create fields that better encompass areas at risk and minimize dose to normal tissues.

To evaluate the correlation of various clinic-pathological variables with axillary nodal involvement in T1 breast cancer & to identify a sub-group of T1 cancers, on the basis of observed variables, with a low risk of axillary nodal metastases. Clinico-pathological variables observed included tumor size, lymphovascular invasion (LVI), histological grade of tumor, tumor palpability, estrogen/progesterone (ER/PR) & her2/neu receptors, age, family history, histological type of tumor, axillary nodal metastases for 100 patients without clinically palpable nodes who underwent axillary lymph node dissection in Bombay Hospital & Medical Research Center from March, 2009. Data compiled was analyzed by univariate & multivariate analysis. All the variables viz. tumor size, LVI, histological grade, tumor palpability & ER/PR/Her2 receptor profile, which were found to be significantly associated with axillary lymph node involvement (ALNI) on univariate analysis were also found to be independent predictors of ALNI on multivariate analysis. Age of the patient, family history & histological type of tumor were not significantly correlated with ALNI. None of the 12 patients with tumor biomarker profile of T1a-b tumors without LVI & with histological grade I, had ALNI. The risk of ALNI can be predicted by using various tumor biomarker variables. Based on the predicted risk of ALNI, the management strategy for axilla can be individualized. The omission of operative axillary staging may be considered in patients with low predictive risk of ALNI. PMID:27065659

Well differentiated epithelial cell thyroid cancer is not classified amongst the most aggressive diseases. Notwithstanding, it can potentially both impair quality of life and affect life expectancy. Appropriate treatment has been shown to be crucial in obtaining optimal outcomes on the course of the disease. Successful treatment rests upon strict adherence to confirmed principles of diagnosis, treatment and follow-up. The aim of the position paper is to present the Israeli medical community with a set of commonly accepted principles for the diagnosis, treatment and follow-up of patients with well differentiated epithelial thyroid cancer and in addition to highlight areas of legitimate differences in approach where those differences occur. We have attempted to provide a link between the various medical disciplines involved in care of these patients: family physicians, surgeons, nuclear medicine specialists, oncologists, pathologists, radiologists and endocrinologists; and have attempted to decrease to a minimum areas of uncertainty and to offer a common approach for the best possible care of thyroid cancer patients in Israel. In addition, we find it our duty to point out those areas and resources which, in our opinion, need to be upgraded in Israel and even included in the Israeli official "health basket". PMID:19039917

The task of this panel was to identify and prioritize needs in the area of characterization of diamond and diamond-like-carbon (DLC) films for use in the transportation industry. Until recent advances in production of inexpensive films of diamonds and DLC, it was not feasible that these materials could be mass produced. The Characterization Panel is restricting itself to identifying needs in areas that would be most useful to manufacturers and users in producing and utilizing diamond and DLC coatings in industry. These characterization needs include in-situ monitoring during growth, relation of structure to performance, and standards and definitions.

A standard that may be used as a guide for persons making independent examinations of nuclear materials statements or reports regarding inventory quantities on hand, receipts, production, shipment, losses, etc. is presented. The objective of the examination of nuclear materials statements by the independent auditor is the expression of an opinion on the fairness with which the statements present the nuclear materials position of a nuclear materials facility and the movement of such inventory materials for the period under review. The opinion is based upon an examination made in accordance with auditing criteria, including an evaluation of internal control, a test of recorded transactions, and a review of measured discards and materials unaccounted for (MUF). The standard draws heavily upon financial auditing standards and procedures published by the American Institute of Certified Public Accountants

Full Text Available The Python programming language does not have a built in switch/case control structure as found in many other high level programming languages. It is thought by some that this is a deficiency in the language, and the control structure should be added. This paper demonstrates that not only is the control structure not needed, but that the methods available in Python are more expressive than built in case statements in other high level languages.

Microsphere insulation panels (MIPs) have been developed as lightweight, longlasting replacements for the foam and vacuum-jacketed systems heretofore used for thermally insulating cryogenic vessels and transfer ducts. The microsphere core material of a typical MIP consists of hollow glass bubbles, which have a combination of advantageous mechanical, chemical, and thermal-insulation properties heretofore available only separately in different materials. In particular, a core filling of glass microspheres has high crush strength and low density, is noncombustible, and performs well in soft vacuum.

An American Hepato-Pancreato-Biliary Association (AHPBA)-sponsored consensus meeting of expert panellists met on 15 January 2014 to review current evidence on the management of hilar cholangiocarcinoma in order to establish practice guidelines and to agree consensus statements. It was established that the treatment of patients with hilar cholangiocarcinoma requires a coordinated, multidisciplinary approach to optimize the chances for both durable survival and effective palliation. An adequate diagnostic and staging work-up includes high-quality cross-sectional imaging; however, pathologic confirmation is not required prior to resection or initiation of a liver transplant trimodal treatment protocol. The ideal treatment for suitable patients with resectable hilar malignancy is resection of the intra- and extrahepatic bile ducts, as well as resection of the involved ipsilateral liver. Preoperative biliary drainage is best achieved with percutaneous transhepatic approaches and may be indicated for patients with cholangitis, malnutrition or hepatic insufficiency. Portal vein embolization is a safe and effective strategy for increasing the future liver remnant (FLR) and is particularly useful for patients with an FLR of biliary cancers. PMID:26172136

A spacecraft includes a plurality of solar panels interconnected with a power coupler and an electrically operated device to provide power to the device when the solar cells are insolated. The solar panels are subject to bending distortion when entering or leaving eclipse. Spacecraft attitude disturbances are reduced by mounting each of the solar panels to an elongated boom made from a material with a low coefficient of thermal expansion, so that the bending of one panel is not communicated to the next. The boom may be insulated to reduce its bending during changes in insolation. A particularly advantageous embodiment mounts each panel to the boom with a single mounting, which may be a hinge. The single mounting prevents transfer of bending moments from the panel to the boom.

Crystalline silicon Modules are formed by single silicon photovoltaic cells. Since each one of these cells individually contributes to the overall electric power of the panel, the failure of one of them directly affects to its benefits and performance. To Minimize these negative effects, junction boxes with few bypass diodes are usually included in Photovoltaic Solar panels. A still experimental way to built solar panels is to integrate bypass diodes in every single cell, which would in...

Virginity testing (virginity examination) is a gynecological examination that is intended to correlate the status and appearance of the hymen with previous sexual contact to determine whether a female has had or is habituated to sexual intercourse. Virginity examinations are practiced in many countries, often forcibly, including in detention places; on women who allege rape or are accused of prostitution; and as part of public or social policies to control sexuality. The Independent Forensic Expert Group (IFEG) - thirty-five preeminent independent forensic experts from eighteen countries specialized in evaluating and documenting the physical and psychological effects of torture and ill-treatment - released a statement on the practice in December 2014. In its statement, the IFEG outlines the physical and psychological effects of forcibly conducting virginity examinations on females based on its collective experience. The Group assesses whether, based on the effects, forcibly conducted virginity examinations constitute cruel, inhuman, or degrading treatment or torture. Finally, the IFEG addresses the medical interpretation, relevance, and ethical implications of such examinations. The IFEG concludes that virginity examinations are medically unreliable and have no clinical or scientific value. These examinations are inherently discriminatory and, in almost all instances, when conducted forcibly, result in significant physical and mental pain and suffering, thereby constituting cruel, inhuman and degrading treatment or torture. When virginity examinations are forcibly conducted and involve vaginal penetration, the examination should be considered as sexual assault and rape. Involvement of health professionals in these examinations violates the basic standards and ethics of the professions. PMID:26048511
Previous Advisory Group Meetings have led to IAEA Technical Reports No.15=5 (1974) on thermal discharge, 118 (1970) and 169 (1975) on sampling, storage and analysis methods for marine radioactivity studies, 167 (1975) on design of marine biological studies permitting comparative evaluation, and 172 (1976) on the effects of ionizing radiation on aquative organisms and eco-systems. The aim of the present report was a bringing into perspective not only problems designing radioecological experiments but to describe reliable experimental methodology suitable for a successful evaluation of radioactivity cycling, and of the effects of such radioactive additions to aquatic environments, as a result of nuclear activities. Specific examples are described. Individual studies presented to the Panel have been treated in detail, and constitute 19 separate INIS entries
It is generally recognized that the lack of adequate rules and accepted definitions of liability in the case of nuclear accidents constitutes a serious drawback to the growth of the atomic energy industry. This applies both t o national undertakings and, more particularly, to bilateral or international operations such as those carried out under the auspices of IAEA. The problems will grow even more complicated if countries adopt differing standards. The initial programme of IAEA therefore stresses the need for the establishment of international standards and definitions of areas of responsibility which would do much to harmonize national practices now being formulated in many countries. In order to initiate studies of this problem, the Director General has decided t o call a number of experts, representing various legal systems, together, and entrust them with the task of examining this question. He has appointed Ambassador Paul Ruegger (Switzerland) as Chairman of the panel

Economic evaluations of health interventions pose a particular challenge for reporting. There is also a need to consolidate and update existing guidelines and promote their use in a user friendly manner. The Consolidated Health Economic Evaluation Reporting Standards (CHEERS) statement is an attempt to consolidate and update previous health economic evaluation guidelines efforts into one current, useful reporting guidance. The primary audiences for the CHEERS statement are researchers reporting economic evaluations and the editors and peer reviewers assessing them for publication. The need for new reporting guidance was identified by a survey of medical editors. A list of possible items based on a systematic review was created. A two round, modified Delphi panel consisting of representatives from academia, clinical practice, industry, government, and the editorial community was conducted. Out of 44 candidate items, 24 items and accompanying recommendations were developed. The recommendations are contained in a user friendly, 24 item checklist. A copy of the statement, accompanying checklist, and this report can be found on the ISPOR Health Economic Evaluations Publication Guidelines Task Force website ( www.ispor.org/TaskForces/EconomicPubGuidelines.asp). We hope CHEERS will lead to better reporting, and ultimately, better health decisions. To facilitate dissemination and uptake, the CHEERS statement is being co-published across 10 health economics and medical journals. We encourage other journals and groups, to endorse CHEERS. The author team plans to review the checklist for an update in five years. PMID:23526140
Since 1993, the World Meteorological Organization (WMO), through the Commission for Climatology and in cooperation with its Members, has issued annual statements on the status of the global climate. This year's statement describes the climatic conditions, including extreme weather events, for the year 2003 and provides a historical perspective on some of the variability and trends that have occurred since the nineteenth century. The statements complement the periodic assessments of the WMO/United Nations Environment Programme (UNEP) Intergovernmental Panel on Climate Change (IPCC), which provide valuable input to national and international negotiations. The information contained in this statement enhances the scientific understanding of the changes in climate and the associated impacts that have occurred in the past, making it possible to improve on our projections for the future

Cancer is a group of diseases which represents a significant public health problem in Mexico and worldwide. In Mexico neoplasms are the second leading cause of death. An increased morbidity and mortality are expected in the next decades. Several preventable risk factors for cancer development have been identified, the most relevant including tobacco use, which accounts for 30% of the cancer cases; and obesity, associated to another 30%. These factors, in turn, are related to sedentarism, alcohol abuse and imbalanced diets. Some agents are well knokn to cause cancer such as ionizing radiation, viruses such as the papilloma virus (HPV) and hepatitis virus (B and C), and more recently environmental pollution exposure and red meat consumption have been pointed out as carcinogens by the International Agency for Research in Cancer (IARC). The scientific evidence currently available is insufficient to consider milk either as a risk factor or protective factor against different types of cancer. PMID:27603890

We present a plane and parabolic collector that absorbs radiant energy and transforms it in heat. Therefore we have a panel to heat water. We study how to increment this capture of solar beams onto the panel in order to increase its efficiency in heating water.
The number of installed solar panels in 2011 has increased again. 40 megawatt of new panels have been installed. This increase is twice as high as the year before. The production of solar power increased to 90 million kWh in 2011 as a result of this expansion. However, the share of solar power in total energy use is still very limited.

Feeling comfortable reading and understanding financial statements is critical to the success of healthcare executives and physicians involved in management. Businesses use three primary financial statements: a balance sheet represents the equation, Assets = Liabilities + Equity; an income statement represents the equation, Revenues - Expenses = Net Income; a statement of cash flows reports all sources and uses of cash during the represented period. The balance sheet expresses financial indicators at one particular moment in time, whereas the income statement and the statement of cash flows show activity that occurred over a stretch of time. Additional information is disclosed in attached footnotes and other supplementary materials. There are two ways to prepare financial statements. Cash-basis accounting recognizes revenue when it is received and expenses when they are paid. Accrual-basis accounting recognizes revenue when it is earned and expenses when they are incurred. Although cash-basis is acceptable, periodically using the accrual method reveals important information about receivables and liabilities that could otherwise remain hidden. Become more engaged with your financial statements by spending time reading them, tracking key performance indicators, and asking accountants and financial advisors questions. This will help you better understand your business and build a successful future. PMID:16095076
Before I begin I have to make a disclaimer. That is that I am going to be talking about public perception because I think that is very important. But I do not want to give the impression that I think the public is wrong. I happen to agree with the public's perception of nuclear power, and I want to make that clear. I do not like the current generation of nuclear plants as I have made clear in many statements that I have made. On the other hand, in the long term, I feel that we have only two choices on the supply side, and that is nuclear power and solar electricity. And although I think solar electricity has the best chance, I am realistic enough to know that technologies do not always work the way I want. And so I think it is necessary to have at least some kind of nuclear option available. On the other hand, I do not think just any kind of nuclear technology will do. I want to talk to you about the conditions that I think you have to take into account when you try to design reactors that are publicly acceptable. I look at this as an insurance policy. Again, I do not want to be misquoted: I think nuclear power should be considered as an insurance policy, not as our first line of defense. Having made those disclaimers, what we need to do is set out a problem statement. The problem statement I set out is, 'How could one design and demonstrate a nuclear reactor that would regain public confidence in the United States, if one chose to do that?' By regaining confidence, I mean regaining sufficient confidence to site reactors at a number of locations. It is a pretty heavy task because the public cannot judge the technical issues. They have to judge the players by their characters and their histories, just as the way we calibrate anyone that knows things that we do not. I have three theses that I think are crucial. The first is that people do not believe in the claims of advocates, of any point of view, not just nuclear power, once the advocates have been proved wrong on
Background: The present paper is an update of the practical guidelines for radiotherapy of breast cancer published in 2006 by the breast cancer expert panel of the German Society of Radiation Oncology (DEGRO). These recommendations have been elaborated on the basis of the S3 guidelines of the German Cancer Society that were revised in March 2007 by an interdisciplinary panel. Methods: The DEGRO expert panel performed a comprehensive survey of the literature, comprising lately published meta-analyses, data from recent randomized trials and guidelines of international breast cancer societies, referring to the criteria of evidence-based medicine. In addition to the more general statements of the German Cancer Society, this paper emphasizes specific radiotherapeutic aspects. It is focused on radiotherapy after breast-conserving surgery. Technique, targeting, and dose are described in detail. Results: Postoperative radiotherapy significantly reduces rates of local recurrence. The more pronounced the achieved reduction is, the more substantially it translates into improved survival. Four prevented local recurrences result in one avoided breast cancer death. This effect is independent of age. An additional boost provides a further absolute risk reduction for local recurrence irrespective of age. Women > 50 years have a hazard ratio of 0.59 in favor of the boost. For DCIS, local recurrence was 2.4% per patient year even in a subgroup with favorable prognostic factors leading to premature closure of the respective study due to ethical reasons. For partial-breast irradiation as a sole method of radiotherapy, results are not yet mature enough to allow definite conclusions. Conclusion: After breast-conserving surgery, whole-breast irradiation remains the gold standard of treatment. The indication for boost irradiation should no longer be restricted to women ≤ 50 years. Partial-breast irradiation is still an experimental treatment and therefore discouraged outside controlled

The ALANAM (Association of Latin American National Academies of Medicine) statement on public health policy, issued following its 19th Congress, held October 28–30, 2010, in Santiago, Chile, declares that cardiovascular diseases, cancer, accidents and violence are the leading causes of death in the region, while in several of its member nations, emergent and re-emergent infectious diseases, malnutrition, and mother-child illnesses remain prevalent. The statement calls attention to the lack of functioning water supply and sewage systems in many villages and rural areas. After describing the social causes of the present state of public health in Latin America (poverty levels reaching upwards of 44% of the total population, or some 110 million people), it calls on governments, first, to spare no efforts in the task of eradicating extreme poverty in the short-term, and poverty in the long-term. Second, considering that about 15 million 3-to-6 year-olds have no access to education, it recommends extending educational services to these children, and to improve the quality of existing pre-school and primary education. Third, the statement calls for universal health care coverage and for equal access to good quality medical care for everyone, and for programs aimed at promoting healthy personal habits and self-care. In this regard, it also recommends that disease prevention programs be sustained over time, that national sanitary objectives be defined, and that its results be periodically reviewed. Fourth, it recommends that primary health care be extended to everyone, and that it be enhanced by improving coverage and coordination with secondary and tertiary level health care institutions. The statement lays special stress on the need for adopting public health policies aimed at lowering the cost of medicines; to this end, it calls for the creation of an official list of generic drugs. The statement ends by calling on governments to support public health research as a

The principal concern of the Oil, Chemical and Atomic Workers Union is that the health impact that the mining of uranium has on our members. The US Public Health Service has determined through mortality studies that the number one cause of death among uranium miners is lung cancer. It was also determined that exposure to radon daughters and mine dust correlates with the lung cancer experience of uranium miners. Data from the US Mine Safety and Health Administration has also shown that not only uranium underground miners, but all underground miners, are exposed to radon daughters - especially underground miners in the Rocky Mountain region. Our Union has maintained a consistent posture in relation to carcinogens in the workplace - that is, exposure to cancer-causing agents should be limited to the lowest feasible level. OCAW has interpreted lowest feasible level as the lower limit of detection of the collection and analytical method used to detect the carcinogen. Our posture is based on the available scientific information on carcinogenesis

The Environmental Impact Statement on the Concept for Disposal of Canada's Nuclear Fuel Waste was released in October 1994 in response to the guidelines issued in 1992 by a panel formed to evaluate this concept (Federal Environmental Assessment Review Panel, 1992). This response is primarily a statement of deficiencies and thus focuses on the negative aspects of the Environmental Impact Statement (EIS). The staff review of the EIS was based on the AECB mandate, which is to protect human health and the environment and as such was focused on technical issues in the EIS. These were performance assessment of the multiple barrier system, environmental impacts, concept feasibility, siting, transport and safety as well as general issues o f regulatory policy and criteria. 30 refs
Two designs of a microscale electron ionization (EI) source are analyzed herein: a 3-panel design and a 4-panel design. Devices were fabricated using microelectromechanical systems technology. Field emission from carbon nanotube provided the electrons for the EI source. Ion currents were measured for helium, nitrogen, and xenon at pressures ranging from 10-4 to 0.1 Torr. A comparison of the performance of both designs is presented. The 4-panel microion source showed a 10x improvement in performance compared to the 3-panel device. An analysis of the various factors affecting the performance of the microion sources is also presented. SIMION, an electron and ion optics software, was coupled with experimental measurements to analyze the ion current results. The electron current contributing to ionization and the ion collection efficiency are believed to be the primary factors responsible for the higher efficiency of the 4-panel microion source. Other improvements in device design that could lead to higher ion source efficiency in the future are also discussed. These microscale ion sources are expected to find application as stand alone ion sources as well as in miniature mass spectrometers.
In 1992 AECL Research convened a panel of external hydrogeological experts consisting of P.A. Domenico, G.E. Grisak, and F.W. Schwartz, to review AECL's proposed approach to siting a geological repository in the rocks of the Canadian Shield for the safe disposal of Canada's nuclear fuel wastes. In particular the panel was asked to provide its opinion on 1) the soundness of the technical approach developed to characterize the groundwater flow systems for the purpose of selecting a location for a disposal vault, 2) the validity and effectiveness of the geological case study used to demonstrate the performance assessment methodology based on the hydrogeological conditions observed at the Whiteshell Research Area, and 3) the adequacy of the hydrogeological information that AECL proposes to use in its Environmental Impact Statement (EIS) of the disposal concept. This report presents the findings, conclusions and recommendations of the hydrogeology review panel. The report was submitted to AECL Research in 1992 December. (author). 24 refs., 2 tabs., 4 figs

Full Text Available Detection of clinically actionable mutations in diagnostic tumour specimens aids in the selection of targeted therapeutics. With an ever increasing number of clinically significant mutations identified, tumour genetic diagnostics is moving from single to multigene analysis. As it is still not feasible for routine diagnostic laboratories to perform sequencing of the entire cancer genome, our approach was to undertake targeted mutation detection. To optimise our diagnostic workflow, we evaluated three target enrichment strategies using two next-generation sequencing (NGS platforms (Illumina MiSeq and Ion PGM. The target enrichment strategies were Fluidigm Access Array custom amplicon panel including 13 genes (MiSeq sequencing, the Oxford Gene Technologies (OGT SureSeq Solid Tumour hybridisation panel including 60 genes (MiSeq sequencing, and an Ion AmpliSeq Cancer Hotspot Panel including 50 genes (Ion PGM sequencing. DNA extracted from formalin-fixed paraffin-embedded (FFPE blocks of eight previously characterised cancer cell lines was tested using the three panels. Matching genomic DNA from fresh cultures of these cell lines was also tested using the custom Fluidigm panel and the OGT SureSeq Solid Tumour panel. Each panel allowed mutation detection of core cancer genes including KRAS, BRAF, and EGFR. Our results indicate that the panels enable accurate variant detection despite sequencing from FFPE DNA.

Passive barriers to transmission of sound waves at frequencies below 500 Hz require large masses. Active noise cancellation systems, on the other hand, are complicated and expensive. We are developing a method for noise control, using an array of panels of magnetostrictive Metglas, which combines the low mass and flexibility of active noise control with the relatively low cost and simplicity of passive noise control. The method is based on the well known fact that an acoustic panel with a reaction mass, resonant at the frequency of the sound wave, will completely reflect that wave, simulating an infinite mass. By wrapping a coil around each Metglas panel, and terminating the coil in an impedance, the stiffness of the Metglas, and hence the resonant frequency of the panel, can be controlled by varying the terminal impedance. By choosing a terminal impedance which is itself frequency dependent, the panel can be made to resonate, and hence to have effective infinite mass, at all frequencies (over some fairly large range) simultaneously. This generally requires negative impedance, which can be produced by a simple circuit with an amplifier and feedback loop. In effect, the Metglas acts like both microphone and speaker in an active noise control system. Preliminary experimental results will be presented.

Whole-genome radiation hybrid (RH) mapping has proven to be a powerful tool for mapping genes and comparing genome architecture. We describe a protocol for constructing RH panels by rescuing irradiated fibroblast donor cells of any mammalian species by polyethylene glycol fusion to a thymidine kinase-deficient hamster cell line. Characterization and expansion of a panel of 90-100 cell lines can be used to map virtually any PCR-based marker that can be distinguished from the recipient hamster genome. The described procedure has been used successfully to create RH panels from diverse mammalian species such as macaques, elephants, alpacas, and armadillos, and may be applicable to nonmammalian vertebrates as well.

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.
Can one build a solar thermal collector which reaches 400 °C even without using focusing mirrors? Yes we can, says SRB Energy, a company aiming at industrially producing a flat panel solar collector patented at CERN in 2003. The distinctive feature of this collector is the high efficiency achieved thanks to the vacuum maintained by a getter pump powered by the sun.

The use of Internet panels to collect survey data is increasing because it is cost-effective, enables access to large and diverse samples quickly, takes less time than traditional methods to obtain data for analysis, and the standardization of the data collection process makes studies easy to replicate. A variety of probability-based panels have been created, including Telepanel/CentERpanel, Knowledge Networks (now GFK KnowledgePanel), the American Life Panel, the Longitudinal Internet Studies for the Social Sciences panel, and the Understanding America Study panel. Despite the advantage of having a known denominator (sampling frame), the probability-based Internet panels often have low recruitment participation rates, and some have argued that there is little practical difference between opting out of a probability sample and opting into a nonprobability (convenience) Internet panel. This article provides an overview of both probability-based and convenience panels, discussing potential benefits and cautions for each method, and summarizing the approaches used to weight panel respondents in order to better represent the underlying population. Challenges of using Internet panel data are discussed, including false answers, careless responses, giving the same answer repeatedly, getting multiple surveys from the same respondent, and panelists being members of multiple panels. More is to be learned about Internet panels generally and about Web-based data collection, as well as how to evaluate data collected using mobile devices and social-media platforms. PMID:26170052

The American Meteorological Society (AMS) has prepared a draft policy statement on geoengineering the climate system, which the AMS Council is considering for approval. The statement notes, “Geoengineering will not substitute for either aggressive mitigation or proactive adaptation. It could contribute to a comprehensive risk management strategy to slow climate change and alleviate its negative impacts, but the potential for adverse and unintended consequences implies a need for adequate research, appropriate regulation, and transparent consideration.” The statement, if adopted, indicates that AMS recommends enhanced research on the scientific and technological potential for geoengineering the climate system; additional study of the historical, ethical, legal, political, and societal aspects of the geoengineering issues; and the development and analysis of policy options to promote transparency and international cooperation in exploring geoengineering options along with restrictions on reckless efforts to manipulate the climate system. AMS is accepting comments on the draft statement until 23 April. For more information, visit http://ametsoc.org/policy/draftstatements/index.html#draft.

Despite subtle differences in their definition and purpose, these terms are often used interchangeably. We systematically assessed the methodological quality of consensus statements and clinical practice guidelines published in three commonly read, geographically diverse, cancer-specific journals. Methods Consensus statements and clinical practice guidelines published between January 2005 and September 2013 in Current Oncology, European Journal of Cancer and Journal of Clinical Oncology were evaluated. Each publication was assessed using the Appraisal of Guidelines for Research and Evaluation II (AGREE II rigour of development and editorial independence domains. For assessment of transparency of document development, 7 additional items were taken from the Institute of Medicine's standards for practice guidelines and the Journal of Clinical Oncology guidelines for authors of guidance documents.

@@ The phenomenon of striation has been investigated experimentally in a macroscopic ac-plasma display panel (PDP). The relationship between the characteristics of striation and the operation conditions including voltage, frequency, rib, and electrode configuration, etc is obtained experimentally. The origin of the striations is considered to be the ionization waves in the transient positive column near the dielectric surface in the anode area during the discharge, and the perturbation is caused by resonance kinetic effects in inert gas.

whether DMPA or NET-EN caused these cancers or instead failed to prevent them. Despite more than 18 years of use and an estimated 13 million women who have ever used DMPA or NET-EN, no case has been recorded of an endometrial malignancy in women so exposed. There is no evidence at this stage of a causal association, either anecdotal or scientific. No evidence of an increased risk of malignant and premalignant disease of the uterine cervix has been found in DMPA users. There is sufficient evidence from investigations in several countries that DMPA and NET-EN may increase both milk production and the duration of lactation. The only clinical metabolic effect attributed to DMPA is weight gain. NET-EN and DMPA are associated with disruption of the menstrual cycle and irregular bleeding. PMID:12338511

Three stiffened panel concepts are evaluated to find optimized designs for integral stiffeners in the barrels of Reusable Launch Vehicle fuel tanks. The three panel concepts considered are a T-stiffened panel, a panel with one blade stiffener centered between each pair of T-stiffeners, and a panel with two blade stiffeners equally spaced between each pair of T-stiffeners. The panels are optimized using PASCO for a range of compressive loads, and the computed areal weight for each panel is used to compare the concepts and predict tank weights. The areal weight of the T-stiffened panel with one blade is up to seven-percent lower than the other panel concepts. Two tank construction methods are compared for a representative tank design with three barrels. In the first method, 45-degree circumferential sections of a barrel are each designed to carry the same maximum load in the barrel. In the second method, each barrel section is designed for the maximum load in that section. Representative tanks designed with the first method are over 250 lb heavier than tanks designed using the second method. Optimized panel designs and areal weights are also computed for variation of the nominal panel length and skin thickness.
