  1. Whole pelvic helical tomotherapy for locally advanced cervical cancer: technical implementation of IMRT with helical tomothearapy

    International Nuclear Information System (INIS)

    To review the experience and to evaluate the treatment plan of using helical tomotherapy (HT) for the treatment of cervical cancer. Between November 1st, 2006 and May 31, 2009, 10 cervical cancer patients histologically confirmed were enrolled. All of the patients received definitive concurrent chemoradiation (CCRT) with whole pelvic HT (WPHT) followed by brachytherapy. During WPHT, all patients were treated with cisplatin, 40 mg/m2 intravenously weekly. Toxicity of treatment was scored according to the Common Terminology Criteria for Adverse Events v3.0 (CTCAE v3.0). The mean survival was 25 months (range, 3 to 27 months). The actuarial overall survival, disease-free survival, locoregional control and distant metastasis-free rates at 2 years were 67%, 77%, 90% and 88%, respectively. The average of uniformity index and conformal index was 1.06 and 1.19, respectively. One grade 3 of acute toxicity for diarrhea, thrombocytopenia and three grade 3 leucopenia were noted during CCRT. Only one grade 3 of subacute toxicity for thrombocytopenia was noted. There were no grade 3 or 4 subacute toxicities of anemia, leucopenia, genitourinary or gastrointestinal effects. Compared with conventional whole pelvic radiation therapy (WPRT), WPHT decreases the mean dose to rectum, bladder and intestines successfully. HT provides feasible clinical outcomes in locally advanced cervical cancer patients. Long-term follow-up and enroll more locally advanced cervical carcinoma patients by limiting bone marrow radiation dose with WPHT technique is warranted

  2. Technical officer's experience in supporting Technical Cooperation (TC) projects implementation

    International Nuclear Information System (INIS)

    Full text: The Technical Cooperation Department of the IAEA helps to transfer nuclear and related technologies for peaceful use to countries throughout the world. The TC Programme disburses more than US$70 million worth of equipment, services, and training per year in approximately 100 countries and territories which are grouped into four geographic regions. With almost 200 staff members, the TC Department works in full partnership with Technical Officers (TOs) from the Technical Departments within the Agency and project counterparts in the recipient Member States. In addition, TC collaborates with the World Bank and other organizations to plan and execute projects in harmony with Member States' needs. Through training courses, expert missions, fellowships, scientific visits, and equipment disbursement, the Technical Cooperation Programme provides the necessary skills and equipment to establish sustainable technology in the counterpart country or region. With more than 800 on-going projects, the TC Programme strives to have an impact on Member State problems that can be solved with nuclear technology. The role of TOs seems to be just supportive for the entire process. However, do we know, what are the duties of the TO? The role and duties of a TO are usually very much underestimated. Terms as 'technical advice and input' say a little about actual TO's work, who in fact is managing the project, finding and coaching the experts, specifying and organizing expert missions and workshops, working a lot on visits of national consultants and scientific visits, writing terms of reference/statements of work for procurement/subcontracts, performing technical evaluation of tenders, managing the projects dealing with subcontracts, coaching the counterparts, etc., etc. Not having the list above of real TO's duties and activities, one will never estimate in a realistic manner the workload and staff needed or a reasonable number of projects for one TO that can be implemented in a

    Full Text Available The 2013 Institute of Medicine report investigating cancer care concluded that the cancer care delivery system is in crisis due to an increased demand for care, increasing complexity of treatment, decreasing work force and rising costs. Engaging patients and incorporating evidence-based care into routine clinical practice are essential components of a high quality cancer delivery system. However, a gap currently exists between the identification of beneficial research findings and application in clinical practice. Implementation research strives to address this gap. In this review, we discuss key components of high quality implementation research. We then apply these concepts to a current cancer care delivery challenge in women’s health, specifically the implementation of a surgery decision aid for women newly diagnosed with breast cancer.

    1985-01-01

    An analysis is presented of the process of implementing advanced manufacturing technology, based on studies of numerous organizations. This process is seen as consisting of a series of decisions with technical, economic, and political objectives. Frequency decisions involve specifications, equipment, resources/organization, and location. Problems in implementation are viewed as resulting from tradeoffs among the objectives, the tendency of decision makers to emphasize some objectives at the expense of others, and the propensity of problems to spread from one area to another. Three sets of recommendations, based on this analysis, are presented.

    The Uranium Mill Tailings Remedial Action (UMTRA) Project Technical Assistance contractor (TAC) Quality Assurance Implementation Plan (QAIP) outlines the primary requirements for integrating quality functions for TAC technical activities applied to the surface and ground water phases of the UMTRA Project. The QAIP is subordinate to the latest issue of the UMTRA Project TAC Quality Assurance Program Plan (QAPP) (DOE, 1993a), which was developed using US Department of Energy (DOE) Order 5700.6C quality assurance (QA) criteria. The QAIP addresses technical aspects of the TAC UMTRA Project surface and ground water programs. All QA issues in the QAIP shall comply with requirements contained in the TAC QAPP (DOE, 1933a). Because industry standards for data acquisition and data control are not addressed in DOE Order 5700.6C, the QAIP has been formatted to the 14 US Environmental Protection Agency (EPA) Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA) QA requirements. DOE Order 5700.6C criteria that are not contained in the CERCLA requirements are added to the QAIP as additional requirements in Sections 15.0 through 18.0. Project documents that contain CERCLA requirements and 5700.6 criteria shall be referenced in this document to avoid duplication. Referenced documents are not included in this QAIP but are available through the UMTRA Project Document Control Center.

    In June 2004 the U.S. Nuclear Regulatory Commission (NRC) amended its fire protection requirements to permit existing nuclear power reactor licensees to voluntarily adopt fire protection requirements contained in National Fire Protection Association (NFPA) Standard 805. NFPA 805 is a performance-based standard for nuclear power plant fire protection that is an alternative to the deterministic, prescriptive fire protection requirements, such as 10 CFR 50 Appendix R, that was issued in 1980. One aspect of implementing NFPA 805 is that the licensee adopts the performance goals, objectives, and criteria for nuclear safety specified in the Standard. These goals, objectives, and criteria can be met through the implementation of deterministic approaches or performance-based approaches, including engineering analyses, probabilistic risk assessment, and fire modeling. Licensees voluntarily adopting the fire protection requirements in NFPA 805 must submit a license amendment request (LAR) to the NRC. The LAR provides the new proposed fire protection licensing basis, including the methodology and results of required evaluations and analyses that show how the NFPA 805 performance criteria are met. As of August 2014, licensees have submitted LARs for 26 nuclear power plants, representing 42 nuclear reactor units. Of these, 7 nuclear power plants, representing 10 nuclear reactor units, have been issued a safety evaluation (SE) by the NRC approving transition of their fire protection licensing basis to one that complies with NFPA 805. Pacific Northwest National Laboratory (PNNL) supports the NRC staff’s technical review of the LARs in the areas of fundamental fire protection, safe shutdown analysis, and Probabilistic Risk Assessment (PRA). PNNL, of course, cannot speak for the nuclear industry and its choice of implementation strategies or the NRC staff’s assessment of the approaches being taken to adopt NFPA 805. However, as a reviewer of the technical details of these

    The VLA Sky Survey (VLASS) was initiated to exploit the science and technical opportunities for a new large radio astronomical survey using the Karl G. Jansky Very Large Array. In March 2015, the proposal for the VLASS underwent a formal Community Review. What emerged from this review is a 5400 hour project to survey the 33885 square degrees of the sky above Declination -40 degrees from 2-4 GHz at 2MHz frequency resolution and 2.5" angular resolution. Over the survey duration of 7 years, each area of the sky will be covered in 3 epochs spaced 32 months apart, to a depth of 0.12mJy/beam rms noise per epoch (0.07mJy/beam combined) in total intensity (Stokes I) and including full polarization. Observations are planned to commence in mid-2016. The raw data will be available in the NRAO archive immediately with no proprietary period and science data products will be provided to the community in a timely manner.In this presentation we describe the survey design and the Technical Implementation Plan (TIP) for the VLASS. The VLASS Basic Data Products (BDP) that will be produced by the survey team include: raw and calibrated visibility data, quick-look continuum images, single-epoch images and spectral image cubes, single-epoch basic object catalogs, and cumulative "static sky" images and image cubes and basic object catalogs to the full survey depth. Calibration, image processing, and analysis for the VLASS will be carried out through automated pipelines being developed at NRAO. Integral to this workflow is maintaining Quality Assurance throughout the system from telescope to archive. The storage and archive services budgeted for the BDP is 1PB for the data and images combined. Significantly higher storage would be required to serve the highest spectral resolution spectral cubes over the full sky area, and thus devising an affordable strategy for providing these services is critical, for example through "Processing on Demand" based on user query of the archive. We will

  16. Basic and technical research on lung cancer

    International Nuclear Information System (INIS)

    In association with clinical study of carbon beam therapy for lung cancer, the basic research for lung cancer and the patients with this disease has been carried out for the past 10 years. With regard to lung damage by the carbon beams, firstly pulmonary function was measured and analyzed for the patients with stage I non-small cell lung cancer. Force expiratory volume in 1 second (FVE 1.0) and TLC (total lung capacity) was found to be reduced significantly at 6 and 12 months after therapy but the reduction rate was a little, which can support the safety of this treatment modality. Secondly, the regional lung damage by the beams was investigated by using correct fusion of CT images with carbon beam dose distribution, diagnostic follow-up CT images and blood flow and ventilation spect images. It demonstrated the graded decrease blood flow by dose and the compensatory increase of blood flow in the adjacent lobe of lung unexposed to irradiation. On the other hand, the biological study of carbon beam effects on lung cancer cells and tumors line was conducted. Firstly, by using 7 or 4 human lung cancer cell line, the radiosensitivity of carbon beams was compared with that of photons by different histological patterns. It was found that there was no essential difference in the sensitivity pattern for lung cancer histology between the carbon beams and photons though the former doubled the later in power. Secondly, by using IA cell lines among them, the dynamic of clonogenic cells (clonogen) in a nude tumor and the changes in its morphology following irradiation was investigated, clarifying that the clonogen proliferating under anoxic or hypoxic conditions played a pivotal role for tumor regrowth and stemmed from the different clone which had been genetically selected and developed under these conditions. The finding of clonogen becomes one of the evidence supporting the superiority of a single-dose radiotherapy to fractionated radiotherapy. (author)

    On January 14, 1993, NASA Langley Research Center (LaRC) made approximately 130 formal, 'unclassified, unlimited' technical reports available via the anonymous FTP Langley Technical Report Server (LTRS). LaRC was the first organization to provide a significant number of aerospace technical reports for open electronic dissemination. LTRS has been successful in its first 18 months of operation, with over 11,000 reports distributed and has helped lay the foundation for electronic document distribution for NASA. The availability of World Wide Web (WWW) technology has revolutionized the Internet-based information community. This paper describes the transition of LTRS from a centralized FTP site to a distributed data model using the WWW, and suggests how the general model for LTRS can be applied to other similar systems.

    Underserved communities with high cancer rates often are not involved in implementing state cancer control activities locally. An East Tennessee State University research team formed 2 Appalachian Community Cancer Research Review Work Groups, 1 in northeast Tennessee and 1 in southwest Virginia. During 4 sessions, the research team presented regional cancer data to the work groups. Work group participants explored research from a lay perspective and identified possible reasons for cancer disparities in central Appalachia. The fifth session was a community dissemination activity in which work group participants engaged in cancer education and action by presenting the research to their local communities in unique ways. During a sixth session, both work groups discussed these interventions and further attempted to answer the question, "What makes the experience of cancer unique in Appalachia?" This article describes the key steps of this community-based participatory research process. PMID:19080040

    Behringer, Bruce; Lofton, Staci; Knight, Margaret L

    2010-12-01

    The comprehensive cancer control approach is used by state, tribes, tribal organizations, territorial and Pacific Island Jurisdiction cancer coalitions to spur local implementation of cancer plans to reduce the burden of cancer in jurisdictions across the country. There is a rich diversity of models and approaches to the development of relationships and scope of planning for cancer control activities between coalitions and advocates in local communities. The national comprehensive cancer control philosophy provides an operational framework while support from the Centers for Disease Control and Prevention enables coalitions to act as catalysts to bring local partners together to combat cancer in communities. This manuscript describes multiple characteristics of cancer coalitions and how they are organized. Two models of how coalitions and local partners collaborate are described. A case study method was used to identify how five different state and tribal coalitions use the two models to organize their collaborations with local communities that result in local implementation of cancer plan priorities. Conclusions support the use of multiple organizing models to ensure involvement of diverse interests and sensitivity to local cancer issues that encourages implementation of cancer control activities.

    Oral, cervical and breast cancers, which are either preventable and/or amenable to early detection and treatment, are the leading causes of cancer-related morbidity and mortality in India. In this paper, we describe implementation science research priorities to catalyze the prevention and control of these cancers in India. Research priorities were organized using a framework based on the implementation science literature and the World Health Organization's definition of health systems. They addressed both community-level as well as health systems-level issues. Community-level or "pull" priorities included the need to identify effective strategies to raise public awareness and understanding of cancer prevention, monitor knowledge levels, and address fear and stigma. Health systems-level or "push" and "infrastructure" priorities included dissemination of evidence- based practices, testing of point-of-care technologies for screening and diagnosis, identification of appropriate service delivery and financing models, and assessment of strategies to enhance the health workforce. Given the extent of available evidence, it is critical that cancer prevention and treatment efforts in India are accelerated. Implementation science research can generate critical insights and evidence to inform this acceleration. PMID:25987015

  5. New generation of breast cancer clinical trials implementing molecular profiling

    Institute of Scientific and Technical Information of China (English)

    Dimitrios Zardavas; Martine Piccart-Gebhart

    2016-01-01

    The implementation of molecular profiling technologies in oncology deepens our knowledge for the molecular landscapes of cancer diagnoses, identifying aberrations that could be linked with specific therapeutic vulnerabilities. In particular, there is an increasing list of molecularly targeted anticancer agents undergoing clinical development that aim to block specific molecular aberrations. This leads to a paradigm shift, with an increasing list of specific aberrations dictating the treatment of patients with cancer. This paradigm shift impacts the field of clinical trials, since the classical approach of having clinico-pathological disease characteristics dictating the patients' enrolment in oncology trials shifts towards the implementation of molecular profiling as pre-screening step. In order to facilitate the successful clinical development of these new anticancer drugs within specific molecular niches of cancer diagnoses, there have been developed new, innovative trial designs that could be classified as follows: i) longitudinal cohort studies that implement (or not) "nested" downstream trials, 2) studies that assess the clinical utility of molecular profiling, 3) "master" protocol trials, iv) "basket" trials, v) trials following an adaptive design. In the present article, we review these innovative study designs, providing representative examples from each category and we discuss the challenges that still need to be addressed in this era of new generation oncology trials implementing molecular profiling. Emphasis is put on the field of breast cancer clinical trials.

    1992-01-01

    Total Quality Management (TQM) is a cooperative form of doing business that relies on the talents of everyone in an organization to continually improve quality and productivity, using teams and an assortment of statistical and measurement tools. The objective of the activities described in this paper was to implement effective improvement tools and techniques in order to build work processes which support good management and technical decisions and actions which are crucial to the success of the ACRV project. The objectives were met by applications in both the technical and management areas. The management applications involved initiating focused continuous improvement projects with widespread team membership. The technical applications involved applying proven statistical tools and techniques to the technical issues associated with the ACRV Project. Specific activities related to the objective included working with a support contractor team to improve support processes, examining processes involved in international activities, a series of tutorials presented to the New Initiatives Office and support contractors, a briefing to NIO managers, and work with the NIO Q+ Team. On the technical side, work included analyzing data from the large-scale W.A.T.E.R. test, landing mode trade analyses, and targeting probability calculations. The results of these efforts will help to develop a disciplined, ongoing process for producing fundamental decisions and actions that shape and guide the ACRV organization .

  10. Radiotherapy in Palliative Cancer Care: Development and Implementation

    International Nuclear Information System (INIS)

    on Cancer, the International Union against Cancer and the International Network for Cancer Treatment and Research (INCTR), to design, implement and integrate comprehensive and cost effective national cancer programmes across all areas of cancer control and treatment, including palliative care. It is important to note that palliative care is not only care of the dying, since even with advanced and disseminated cancer, patients are now living longer. The goal of palliative care is to relieve symptoms effectively and efficiently and to maintain the maximum quality of life for the duration of the patient's life. The interventions recommended depend on the patient's clinical status, severity of disease, and the location of the symptomatic site. Radiotherapy has an important role to play as a cost effective and simple method to relieve symptoms caused by bone or brain metastases, tumour bleeding, or visceral/lymphovascular obstruction due to cancer. This report was written following an IAEA consultants meeting in October 2007 and further electronic communications. The aims of the discussions were to: recognize and document the diversity and complexity of cancer types, rates, diagnoses and treatments worldwide; and to provide guidelines to ensure optimum delivery of comprehensive palliative cancer care. This report makes five recommendations: 1. The management and control of cancer symptoms is needed in all health care systems. There is a shortage of palliative care specialists in all health systems, relative to the number of cancer patients needing palliative care. 2. Because palliative care specialists can reach only a small proportion of the patients in need, palliative care principles and techniques should form a core element of the medical education for all health care providers, and especially for those who regularly treat cancer patients. 3. There is a specific need for training in comprehensive palliative care amongst the radiation oncology community. Radiation

    International Nuclear Information System (INIS)

    The paper deals with the organizational, technical and economic aspects of the implementation of mammographic screening in Ukraine. It is shown that the introduction of preventive mammography is possible only with the digital technologies of the mammograms imaging, which can reduce the cost of operation of the mammographic room, reduce the number of required medical personnel for the screening and the radiation load on the women. However, realization of the benefits of digital mammography is only possible if the correct mammograms are displaying on specialized 5-MP monitors. (authors)

    International Nuclear Information System (INIS)

    The separation nozzle process for the enrichment of uranium-235 has been developed at the Karlsruhe Nuclear Research Center as an alternative to the gaseous diffusion and centrifuge process. The separation of uranium isotopes is achieved by the deflection of a jet of uranium hexafluoride mixed with hydrogen. Since 1970, the German company of STEAG, has been involved in the technological development and commercial implementation of the nozzle process. In 1975, the Brazilian company of NUCLEBRAS, and the German company of Interatom, joined the effort. The primary objective of the common activity is the construction of a separation nozzle demonstration plant with an annual capacity of about 200 000 SWU and the development of components of a commercial plant. The paper covers the most important steps in the development and the technical implementation of the process. (orig.)

  14. Overview of technical barriers and implementation of cellulosic ethanol in the U.S

    International Nuclear Information System (INIS)

    There is mounting concern about the buildup of carbon dioxide (CO2) and other so-called greenhouse gases in the atmosphere. In general, bioethanol production requires minimal fossil fuel input in the conversion step, and ethanol is considered a promising alternative fuel to petroleum-derived products. It is anticipated that ethanol production with second-generation biomass, i.e. lignocellulosic materials, will be possible on a large scale in the near future. Latest efforts have been focused on overcoming technical challenges in bioconversion, particularly pretreatment, and finding the solutions required to implement biorefinery on a large scale. This paper introduces and reviews the current status of research, and of the ethanol industry in the U.S. In addition, other important concepts in biofuels, cellulosic ethanol, and biorefinery in general are reviewed, and the key technical issues in bioconversion of cellulosic ethanol, such as pretreatment and factors affecting bioconversion of biomass are also discussed. - Highlights: • The current status of research, and of the ethanol industry in the U.S. • Important concepts in biofuels, cellulosic ethanol, and biorefinery. • The key technical issues in bioconversion of cellulosic ethanol. • Pretreatment and factors affecting bioconversion of biomass

    Full Text Available Abstract Background To achieve widespread cancer control, a better understanding is needed of the factors that contribute to successful implementation of effective skin cancer prevention interventions. This study assessed the relative contributions of individual- and setting-level characteristics to implementation of a widely disseminated skin cancer prevention program. Methods A multilevel analysis was conducted using data from the Pool Cool Diffusion Trial from 2004 and replicated with data from 2005. Implementation of Pool Cool by lifeguards was measured using a composite score (implementation variable, range 0 to 10 that assessed whether the lifeguard performed different components of the intervention. Predictors included lifeguard background characteristics, lifeguard sun protection-related attitudes and behaviors, pool characteristics, and enhanced (i.e., more technical assistance, tailored materials, and incentives are provided versus basic treatment group. Results The mean value of the implementation variable was 4 in both years (2004 and 2005; SD = 2 in 2004 and SD = 3 in 2005 indicating a moderate implementation for most lifeguards. Several individual-level (lifeguard characteristics and setting-level (pool characteristics and treatment group factors were found to be significantly associated with implementation of Pool Cool by lifeguards. All three lifeguard-level domains (lifeguard background characteristics, lifeguard sun protection-related attitudes and behaviors and six pool-level predictors (number of weekly pool visitors, intervention intensity, geographic latitude, pool location, sun safety and/or skin cancer prevention programs, and sun safety programs and policies were included in the final model. The most important predictors of implementation were the number of weekly pool visitors (inverse association and enhanced treatment group (positive association.

  19. Joint Implementation under the UN Framework Convention on Climate Change. Technical and institutional challenges

    International Nuclear Information System (INIS)

    The UN Framework Convention of Climate Change (FCCC) allows for the Joint Implementation (JI) of measures to mitigate the emissions of greenhouse gases. The concept of JI refers to the implementation of such measures in one country with partial and/or technical support from another country, potentially fulfilling some of the supporting country's emission-reduction commitment under the FCCC. At present, all JI transactions are voluntary, and no country has claimed JI credit against existing FCCC commitments. Nevertheless, JI could have important implications for both the economic efficiency and the international equity of the implementation of the FCCC. The paper discusses some of the information needs of JI projects and seeks to clarify some of the common assumptions and arguments about JI. Issues regarding JI are distinguished according to those that are specific to JI as well as other types of regimes and transactions. The focus is on the position of developing countries and their potential risks and benefits regarding JI. 2 figs., 3 tabs., 35 refs

    2010-01-15

    Background: Computed tomographic colonography (CTC) has gained increased acceptance in the last few years as a valid substitute for double-contrast barium enema (DCBE). However, implementation of new technologies is complex, since several factors may influence the process. Purpose: To evaluate the current situation in Sweden concerning implementation of CTC, as compared to a previous national survey in 2005. Material and Methods: In December 2008, a structured, self-assessed questionnaire regarding implementation and technical performance of CTC was mailed to all radiology departments in Sweden. In March 2009, departments who had not replied were contacted by e-mail or by telephone. All (100%, 119/119) departments answered the questionnaire. Results: CTC is currently performed in 50/119 (42%) departments, i.e., 18 additional departments compared to 2005. Twenty-three out of 60 (38%) responding departments stated that they intend to start to perform CTC in the near future. DCBE is currently performed in 77/119 (65%) departments, 12 departments less compared to 2005. The most common reasons for non-implementation of CTC are non-availability of spiral CT scanner (41%, 26/64) and/or multidetector-row CT scanner (39%, 25/64), and lack of doctors' time (34%, 22/64). Only 3% (2/64) of departments are 'awaiting further scientific documentation' on CTC, a significant reduction compared to 2005 (P=0.002). Until 2009, 59% (29/49) of CTC centers had performed more than 200 CTCs compared to 13% (4/32) of CTC centers in 2005. Intravenous contrast material is routinely administered in 86% (42/49), and carbon dioxide is used to distend the colon in 90% (44/49). Almost all radiology departments (93%, 93/100) currently believe that CTC will 'absolutely' or 'probably' replace barium enema in the future, while in 2005 only 56% (55/99) gave similar answers. Conclusion: The survey reflects a further transition process from DCBE to CTC, with attitudes

    Park, Ah Young; Seo, Bo Kyoung

    2016-01-01

    Real-time magnetic resonance imaging (MRI) navigated ultrasound is an image fusion technique to display the results of both MRI and ultrasonography on the same monitor. This system is a promising technique to improve lesion detection and analysis, to maximize advantages of each imaging modality, and to compensate the disadvantages of both MRI and ultrasound. In evaluating breast cancer stage preoperatively, MRI and ultrasound are the most representative imaging modalities. However, sometimes difficulties arise in interpreting and correlating the radiological features between these two different modalities. This pictorial essay demonstrates the technical principles of the real-time MRI navigated ultrasound, and clinical implementation of the system in preoperative evaluation of tumor extent, multiplicity, and nodal status in breast cancer patients.

  6. New technical knowledge to be implemented to the revision of rules on pipe wall thinning management for PWR plants

    International Nuclear Information System (INIS)

    Rules for PWR plant pipe wall thinning management were formulated by the Japan Society of Mechanical Engineers in 2006. Since then thinning management of Japanese PWR plants has been carried out based on this rule. Pipe wall thinning phenomena to be dealt with in this rule have been identified in many piping components of power plants. New technical knowledge has been accumulated since the issuance of 2006 edition. We have formulated these knowledge and information about the thinning phenomena in PWR power plants. Given the history of application of this rule, we have to make our best effort to carry out a study of latest technical knowledge and implement them to the revision of rule and improve pipe wall thinning management. This paper summarizes the new technical knowledge and basis to be implemented to the revision of rules on pipe wall thinning management for PWR plants in Japan. (author)

    McLoughlin, Kevin [Lawrence Livermore National Lab. (LLNL), Livermore, CA (United States)

    2016-01-11

    This report describes the design and implementation of an algorithm for estimating relative microbial abundances, together with confidence limits, using data from metagenomic DNA sequencing. For the background behind this project and a detailed discussion of our modeling approach for metagenomic data, we refer the reader to our earlier technical report, dated March 4, 2014. Briefly, we described a fully Bayesian generative model for paired-end sequence read data, incorporating the effects of the relative abundances, the distribution of sequence fragment lengths, fragment position bias, sequencing errors and variations between the sampled genomes and the nearest reference genomes. A distinctive feature of our modeling approach is the use of a Chinese restaurant process (CRP) to describe the selection of genomes to be sampled, and thus the relative abundances. The CRP component is desirable for fitting abundances to reads that may map ambiguously to multiple targets, because it naturally leads to sparse solutions that select the best representative from each set of nearly equivalent genomes.

    Full Text Available Abstract Reversible protein phosphorylation is one of the most important forms of cellular regulation. Thus, phosphoproteomic analysis of protein phosphorylation in cells is a powerful tool to evaluate cell functional status. The importance of protein kinase-regulated signal transduction pathways in human cancer has led to the development of drugs that inhibit protein kinases at the apex or intermediary levels of these pathways. Phosphoproteomic analysis of these signalling pathways will provide important insights for operation and connectivity of these pathways to facilitate identification of the best targets for cancer therapies. Enrichment of phosphorylated proteins or peptides from tissue or bodily fluid samples is required. The application of technologies such as phosphoenrichments, mass spectrometry (MS coupled to bioinformatics tools is crucial for the identification and quantification of protein phosphorylation sites for advancing in such relevant clinical research. A combination of different phosphopeptide enrichments, quantitative techniques and bioinformatic tools is necessary to achieve good phospho-regulation data and good structural analysis of protein studies. The current and most useful proteomics and bioinformatics techniques will be explained with research examples. Our aim in this article is to be helpful for cancer research via detailing proteomics and bioinformatic tools.

  11. Implementation of a lung radiosurgery program: technical considerations and quality assurance in an Australian institution

    International Nuclear Information System (INIS)

    The Peter MacCallum Cancer Centre has established a stereotactic lung radiosurgery program for the treatment of isolated lung metastases. The aim of this study was to critically assess the technical feasibility of performing stereotactic lung radiosurgery in an Australian institution. A single 26-Gy fraction of radiotherapy was delivered to patients with positron emission tomography (PET) staged solitary lung metastases. Motion management was addressed using four-dimensional computed tomographic simulation, and cone beam CT (CBCT) online soft-tissue matching. Treatments were with multiple coplanar and non-coplanar asymmetric beams. Patients were immobilised in a dedicated stereotactic body cradle. Quality assurance (QA) of treatment plans with both ion chamber and film measurements was performed accounting for patient-specific respiratory motion. Between February 2010 and February 2011, nine patients received stereotactic lung radiosurgery. One grade 1 toxicity and one grade 2 toxicity were recorded after treatment. The mean planning target volume was 22.6 cc. A median of eight beams were delivered per treatment plan (range 7–10) with a median of two non-coplanar beams (range 0–6). At treatment plan QA, the difference between planned and delivered dose was ≤1.76% in all static and dynamic ion chamber recordings. A mid-treatment CBCT was performed at a median time of 21 min, with the mean displacement discrepancy from initial set-up being 0.4 mm (range 0–2 mm). Stereotactic radiosurgery to the lung was both feasible and tolerable at our institution. Intrafractional immobilisation within 2 mm was reproducible. Excellent concordance between planned and delivered treatments was achieved in the phantom QA.

    Cancer is the leading cause of the death, accounts for about 13% of all annual deaths worldwide. Many different fields of science are collaborating together studying cancer to improve our knowledge of this lethal disease, and find better solutions for diagnosis and treatment. Proteomics is one of the most recent and rapidly growing areas in molecular biology that helps understanding cancer from an omics data analysis point of view. The human proteome project was officially initiated in 2008. Proteomics enables the scientists to interrogate a variety of biospecimens for their protein contents and measure the concentrations of these proteins. Current necessary equipment and technologies for cancer proteomics are mass spectrometry, protein microarrays, nanotechnology and bioinformatics. In this paper, we provide a brief review on proteomics and its application in cancer research. After a brief introduction including its definition, we summarize the history of major previous work conducted by researchers, followed by an overview on the role of proteomics in cancer studies. We also provide a list of different utilities in cancer proteomics and investigate their advantages and shortcomings from theoretical and practical angles. Finally, we explore some of the main challenges and conclude the paper with future directions in this field. PMID:24761843

Management of venous thromboembolism in patients with cancer requires the coordinated efforts of a wide range of clinicians, highlighting the importance of a multidisciplinary approach. However, a lack of consensus among various national and international clinical practice guidelines has contributed to knowledge and practice gaps among practitioners, and inconsistent approaches to venous thromboembolism. The 2013 international guidelines for thrombosis in cancer have sought to address these gaps by critically re-evaluating the evidence coming from clinical trials and synthesizing a number of guidelines documents. An individualized approach to prophylaxis is recommended for all patients.

    2000-08-01

    Carcinoma of the prostate is the most common form of cancer in males in the United States, second only to skin cancer. Recently, there has been increased public awareness of cancer-related diseases and specifically prostate cancer. As a result, more individuals are routinely screened and diagnosed with prostate cancer. When a man first discovers he has prostate cancer, he is faced with a multitude of questions. Health care providers realize in counseling patients that there is no single treatment choice best suited for every patient. Because of multiple treatment choices for prostate cancer and complex counseling needs due to a varied side effect profiles of the different options, the Internet may be an ideal tool to extend the health care provider. Furthermore, because men may be reluctant to discuss issues with the health care provider directly, the anonymity of the Internet may be of particular value in the disease. The Internet has created a massive body of information with an estimated 320 million Web sites. The provider can use the Internet as a patient educational tool thus affording the patient time to absorb sometimes complicated information. The Internet can help patients focus on specific aspects of their disease making the patient-provider encounter more productive and allow the patient to take an active role in the treatment decision-making process. More knowledgeable patients can make better decisions about treatment options and have more realistic expectations of their outcomes. We have developed an Internet-based decision for prostate cancer available to both patients and physicians. PMID:10975497

The NASA STI Program is an agency-wide program charged with gathering, organizing, storing, and disseminating NASA-produced information for research and public use. The program is investigating the use of a new protocol called the Open Archives Initiative (OAI) as a means to improve data interoperability and data collection. OAI promotes the use of the OAI harvesting protocol as a simple way for data sharing among repositories. In two separate initiatives, the STI Program is implementing OAI In collaboration with the Air Force, Department of Energy, and Old Dominion University, the NASA STI Program has funded research on implementing the OAI to exchange data between the three organizations. The second initiative is the deployment of OAI for the NASA technical report server (TRS) environment. The NASA TRS environment is comprised of distributed technical report servers with a centralized search interface. This paper focuses on the implementation of OAI to promote interoperability among diverse data repositories.

    Cancer survivorship care plans (SCPs) have been recommended to improve clinical care and patient outcomes. Research is needed to establish their efficacy and identify best practices. Starting in 2015, centers accredited by the American College of Surgeons Commission on Cancer must deliver SCPs to patients completing primary cancer treatment with curative intent. We describe how we established routine SCP delivery at the Robert H Lurie Comprehensive Cancer Center in Chicago, Illinois, using the Quality Implementation Framework. We evaluated local practices, gathered clinician and patient stakeholder input, developed customized SCP templates within the electronic health record (EHR), and implemented 2 complementary delivery models. Clinician interviews (n = 41) and survey responses (n = 12), along with input from patients (n = 68) and a patient advisory board (n = 15), indicated support for SCPs and survivorship services. To promote feasible implementation and leverage existing workflows, we harmonized 2 SCP delivery models: integrated care within clinics where patients received treatment, and referral to a centralized survivorship clinic. We are implementing SCP delivery with prominent disease sites and will extend services to survivors of other cancers in the future. We developed four electronic disease-specific SCP templates for breast, colorectal, lung, and prostate cancers and a fifth, generic template that can be used for other malignancies. The templates reduced free-text clinician entry by auto-populating 20% of the fields from existing EHR data, and using drop-down menus for another 65%. Mean SCP completion time is 12 minutes (range, 10-15; n = 64). We designed our framework to facilitate ongoing evaluation of implementation and quality improvement.

    Endoscopic submucosal dissection (ESD) is a highly refined technique compared to conventional endoscopic mucosal resection. It enables complete resection of early gastric cancer (EGC) which has no possibility of lymph node metastasis. Indication for ESD of EGC generally entails early gastric cancer confined to the mucosa with well differentiated histology, though there are clinically suitable expanded criteria. As ESD requires specific skill and expertise, endoscopists need to be familiarized with basic methods and the use of special devices. The essence of the technique is to dissect the submucosal layer with direct vision and maintain the cutting plane above the underlying proper muscle layer. Although there are some differences in the detailed technical aspect, the cardinal method of ESD is now well established and standardized. Furthermore, research and development of new ESD devices that render more efficient, safe ESD are still in progress to improve the overall result of ESD on early gastric cancer.

  8. Technical aspects of the deep inspiration breath-hold technique in the treatment of thoracic cancer

    International Nuclear Information System (INIS)

    Purpose: The goal of this paper is to describe our initial experience with the deep inspiration breath-hold (DIBH) technique in conformal treatment of non-small-cell lung cancer with particular emphasis on the technical aspects required for implementation. Methods and Materials: In the DIBH technique, the patient is verbally coached through a modified slow vital capacity maneuver and brought to a reproducible deep inspiration breath-hold level. The goal is to immobilize the tumor and to expand normal lung out of the high-dose region. A physicist or therapist monitors and records patient breathing during simulation, verification, and treatment using a spirometer with a custom computer interface. Examination of internal anatomy during fluoroscopy over multiple breath holds establishes the reproducibility of the DIBH maneuver for each patient. A reference free-breathing CT scan and DIBH planning scan are obtained. To provide an estimate of tumor motion during normal tidal breathing, additional scan sets are obtained at end inspiration and end expiration. These are also used to set the spirometer action levels for treatment. Patient lung inflation is independently verified over the course of treatment by comparing the distance from the isocenter to the diaphragm measured from the DIBH digitally reconstructed radiographs to the distance measured on the portal films. Patient breathing traces obtained during treatment were examined retrospectively to assess the reproducibility of the technique. Results: Data from the first 7 patients, encompassing over 250 treatments, were analyzed. The inferred displacement of the centroid of gross tumor volume from its position in the planning scan, as calculated from the spirometer records in over 350 breath holds was 0.02 ± 0.14 cm (mean and standard deviation). These data are consistent with the displacements of the diaphragm (-0.1 ± 0.4 cm; range, from -1.2 to 1.1 cm) relative to the isocenter, as measured on the (92) portal films

    Modified radical neck dissection (MRND) is often performed in conjunction with total thyroidectomy for the management of thyroid cancer. Prevention of postoperative sequelae after MRND is closely dependent on the avoidance of technical mistakes that may lead to significant complications and long-term morbidity. A thorough technical discussion with emphasis on potential pitfalls is made of the most relevant steps of MRND using the extrafascial approach: fascial dissection, approach to the accessory nerve, posterior limits, upper internal jugular vein (IJV), transverse cervical vessels, thoracic duct and compartment V dissection. Some anatomical hints are emphasized to help the novice surgeon to develop a refined surgical technique, the key to an uneventful postoperative course. PMID:25083480

    To compare technical and clinical screening performance parameters between computed radiography (CR) and direct digital radiography (DR) systems. The number of women screened with CR was 73,008 and with DR 116,945. Technical and patient dose survey data of 25 CR and 37 DR systems were available. Technical performance was expressed by threshold thickness values at the mean glandular dose (MGD) level of routine practice. Clinical indicators included recall rate (RR), cancer detection rate (CDR), percentage of ductal carcinoma in situ (DCIS), percentage of cancers with T-scores smaller than 1 cm and positive predictive value (PPV). Contrast threshold values for the 0.1-mm gold disk were 1.44 {mu}m (SD 0.13 {mu}m) for CR and 1.20 {mu}m (SD 0.13 {mu}m for DR). MGD was 2.16 mGy (SD 0.36 mGy) and 1.35 mGy (SD 0.32 mGy) for CR and DR respectively. We obtained for CR, respectively DR, the following results: RR in the first round of 5.48 % versus 5.61 %; RR in subsequent rounds of 2.52 % versus 2.65 %; CDR of 0.52 % versus 0.53 %; DCIS of 0.08 % versus 0.11 %; a rate of cancers with T-scores smaller than 1 cm of 0.11 % versus 0.11 %; PPV of 18.45 % versus 18.64 %; none of them was significantly different. Our screening indicators are reassuring for the use of CR and DR, with CR operating at 60 % higher MGD. (orig.)

  16. Considerations for Implementation of Cancer Molecular Diagnostics Into Clinical Care.

    Hayes, Daniel F

    2016-01-01

    Physicians have provided personalized care with as much precision as possible for several centuries. However, increasingly sophisticated understanding of the human genome and of cancer biology has permitted identification of genetic and phenotypic distinctions that might permit development of new tumor biomarker tests for risk categorization, screening, differential diagnosis, prognosis, prediction, and monitoring. Both commercial and academic laboratories are offering tests for single analytes, panels of tests of single analytes, multiparameter assays coalesced into a signature, and total genomic, transcriptomic, or proteomic analyses. However, the absence of a consistent regulatory environment has led to marketing of assays without proven analytic validity or clinical utility. U.S. Food and Drug Administration (FDA) approval or clearance does not necessarily imply that use of the test will improve patient outcomes, and FDA discretion to permit laboratory-developed tests results in unknown benefit, or harm, of others. In this regard, a "bad tumor marker is as bad as a bad drug." Caveat emptor is not a satisfactory approach to delivering high-quality care. Rather, adoption of tumor biomarker tests should be based on high levels of evidence generated in scientifically rigorous studies that demonstrate both analytical validity and clinical utility. Doing so will ensure that clinicians and patients are confident that a tumor biomarker test is likely to improve their outcomes. PMID:27249708

    Full Text Available Background: Locally advanced and unresectable oral cavity cancers have a poor prognosis. Induction might be beneficial in this setting by reducing tumor bulk and allowing definitive surgery. Aim: To analyze the impact of induction chemotherapy on locally advanced, technically unresectable oral cavity cancers. Materials and Methods: Retrospective analysis of patients with locally advanced oral cavity cancers, who were treated with neoadjuvant chemotherapy (NACT during the period between June 2009 and December 2010. Data from a prospectively filled database were analyzed for information on patient characteristics, chemotherapy received, toxicity, response rates, local treatment offered, patterns of failure, and overall survival. The statistical analysis was performed with SPSS version 16. Results: 123 patients, with a median age of 42 years were analyzed. Buccal mucosa was the most common subsite (68.30%. Three drug regimen was utilized in 26 patients (21.10% and the rest received two drug regimen. Resectability was achieved in 17 patients treated with 3 drug regimen (68.00% and 36 patients receiving 2 drug regimen. Febrile neutropenia was seen in 3 patients (3.09% receiving 2 drug regimen and in 9 patients (34.62% receiving 3 drug regimen. The estimated median OS was not reached in patients who had clinical response and underwent surgery as opposed to 8 months in patients treated with non-surgical modality post NACT (P = 0.0001. Conclusion: Induction chemotherapy was effective in converting technically unresectable oral cavity cancers to operable disease in approximately 40% of patients and was associated with significantly improved overall survival in comparison to nonsurgical treatment.

    Full Text Available Introduction. High values of standardized mortality and morbidity rates of standardized cancer mortality in Serbia, especially colorectal, cervical and breast cancer led to creation of national programs for their early detection and engagement of the international support for their implementation. Objective. Assessment of required resources (time, personnel, financial to implement the National program for screening of breast cancer in the Republic of Serbia. Methods. Three possible scenarios have been prepared (optimistic, realistic and pessimistic based on the expected coverage by screening of women aged 45 to 69 years, and time, personnel and financial feasibility estimates were made for a two-year screening cycle. Results. Time aspect of feasibility even under conditions of “relaxation” of the assumption on the number of working days during the year did not question feasibility of any of the scenarios. Personnel feasibility is only possible in the pessimistic scenario, while the financial feasibility only makes sense in optimistic scenario as the least unfavorable solution due to economies of scale. Conclusion. Establishment of the initial base of skilled radiologists and radiology technicians and the system for their continuous medical education as well as allocation of specific MoH budget line for screening program expenditures, along with donated mammographs and good organization and coordination, may provide unobstructed implementation of the National program for early detection of breast cancer in the Republic of Serbia.

    Full Text Available Currently a popular area in nanomedicine is the implementation of plasmonic gold nanoparticles for cancer diagnosis and photothermal therapy, attributed to the intriguing optical properties of the nanoparticles. The surface plasmon resonance, a unique phenomenon to plasmonic (noble metal nanoparticles leads to strong electromagnetic fields on the particle surface and consequently enhances all the radiative properties such as absorption and scattering. Additionally, the strongly absorbed light is converted to heat quickly via a series of nonradiative processes. In this review, we discuss these important optical and photothermal properties of gold nanoparticles in different shapes and structures and address their recent applications for cancer imaging, spectroscopic detection and photothermal therapy.

    Patricia P. Lillquist, PhD, MSW

    2008-04-01

    Full Text Available IntroductionThis research aimed to explore differences in the implementation of case management among local breast cancer screening partnerships in New York State after changes in federal public policy in 1998 and to achieve a better understanding of case management in a new and distinct practice setting. Capacity and willingness to implement change were theorized to explain local differences in implementation. Local breast cancer screening programs that received federal funding through the New York State Department of Health were invited to participate in the study.MethodsA mail survey was administered to the directors of New York’s 53 local breast cancer screening partnerships in 2003. The survey included questions about willingness and capacity to implement case management and a scale to assess case management program philosophy. Factor analysis and correlations were used to compare willingness and capacity with differences in implementation.ResultsTwo common factors — task focus and self-identity focus — were identified as factors that differentiated case management programs. Task-focus partnerships undertook a broader range of tasks but were less likely to report autonomy in making program changes. Self-identity partnerships were less likely to report difficulties with other agencies and scored highly on innovation, involvement in work, and interest in client service. Having a nurse as the case manager, being aware of the standards of case management, and providing health education were associated with both task focus and self-identity focus.ConclusionThe study identified distinct styles of implementation. These styles have implications for the breadth of services provided, such as whether client-level services only are offered. Interagency coordination was facilitated in partnerships with comprehensive case management.

    2014-09-01

    Public resources should always be managed efficiently, more so in times of crisis. Due to the specific characteristics of the healthcare sector, there is a need for special attention, especially in regards to hospitals. Administrators need useful tools to be able to efficiently manage available resources, such as enterprise resource planning (ERP) systems. Therefore, an analysis of the effects of their implementation and use in hospitals is valuable. This study has two purposes. One is to analyse the role ERP systems play in aiding the integration of hospital data, with focus on user satisfaction as well as possible resistance to change. The other purpose is to analyse the effects of implanting and using ERP systems in the hospital environment and identifying how certain variables influence the process, especially the existence of different organisational cultures. Results indicate that clinical information has become notably more integrated, despite the lack of flow in the economic-financial area. The heterogeneous nature of the different groups, clinical (Medical, Nursing) and non-clinical (Economic-Financial, Accounting), had a negative influence on the implementation process, and limited the integration of information as well as the system's performance.

  10. Case study on the role of socio-technical influences on the implementation and success of nuclear power in France

    International Nuclear Information System (INIS)

    To fully understand a technological development one must appreciate social, political and economic factors in addition to the technological components (Hughes, 1991). The systems perspective, asserted by Hughes, implies that technologies cannot be understood in isolation, but only in their contexts, especially in their systemic contexts. This theory is illustrated through an examination of France's implementation of its nuclear power program in the early 1970's. Nuclear power provided France with the opportunity to achieve energy independence and, as a result, political control over its energy supply. The scope of this case study is limited to consideration of the socio-technical influences on the rise of nuclear power in France and includes an examination of the technical aspects of the innovation. In considering the socio-technical system encompassing France's adoption of nuclear power, this case study will contemplate: how France was able to persuade its people to accept nuclear power; what it is about French culture and politics that allowed them to succeed where most other countries have failed; the breakthroughs that led to the broad commercialization of nuclear power in France in the 1970's; and how France achieved its status as one of the world's top producers of nuclear energy. The time period during which this study is based is limited to the early 1970's, when France was reliant upon external energy supplies, up until the present day, where nuclear power has become France's main source of energy, thus contributing to France's autonomy in terms of its energy supply. This study will not address the issue of nuclear waste or the nuclear power safety debate which is also beyond the scope of this study. (author)

  11. Implementation of the European protocol for quality control of the technical aspects of mammography screening in Bulgaria

    International Nuclear Information System (INIS)

    The results from the national pilot project on implementation of the European protocol for the quality control (QC) of the technical aspects of mammography screening as well as the European protocol for dosimetry in mammography in Bulgaria are presented. A QC programme for mammography equipment and a standardised measurement protocol were created. The full QC programme was tested on four mammography units of different types and ages. A national survey was performed for entrance surface air kerma (ESAK) on 20 units using a 45 mm PMMA standard phantom. Average glandular dose (AGD) was calculated using the conversion coefficients from the European dosimetry protocol. The survey demonstrated considerable differences in the technical condition of the mammography units that resulted in varying image quality. The measured values of ESAK showed significant variations. Doses for ∼45% of the units were found to be below the European reference level. The values for AGD ranged from 0.35 to 3.47 mGy. The main problems found were film processing, optical density (OD) control settings and AEC adjustment. The results showed the importance of film OD measurements parallel to dose measurements. The X-ray mammography in the country needs optimisation. Comprehensive quality assurance programme should be adopted in all departments covering permanent QC of the equipment, image quality and breast dose. (authors)

    Pathology reporting is evolving from a traditional narrative report to a more structured synoptic report. Narrative reporting can cause misinterpretation due to lack of information and structure. In this systematic review, we evaluate the impact of synoptic reporting on completeness of pathology reports and quality of pathology evaluation for solid tumours. Pubmed, Embase and Cochrane databases were systematically searched to identify studies describing the effect of synoptic reporting implementation on completeness of reporting and quality of pathology evaluation of solid malignant tumours. Thirty-three studies met the inclusion criteria. All studies, except one, reported an increased overall completeness of pathology reports after introduction of synoptic reporting (SR). Most frequently studied cancers were breast (n = 9) and colorectal cancer (n = 16). For breast cancer, narrative reports adequately described 'tumour type' and 'nodal status'. Synoptic reporting resulted in improved description of 'resection margins', 'DCIS size', 'location' and 'presence of calcifications'. For colorectal cancer, narrative reports adequately reported 'tumour type', 'invasion depth', 'lymph node counts' and 'nodal status'. Synoptic reporting resulted in increased reporting of 'circumferential margin', 'resection margin', 'perineural invasion' and 'lymphovascular invasion'. In addition, increased numbers of reported lymph nodes were found in synoptic reports. Narrative reports of other cancer types described the traditional parameters adequately, whereas for 'resection margins' and '(lympho)vascular/perineural invasion', implementation of synoptic reporting was necessary. Synoptic reporting results in improved reporting of clinical relevant data. Demonstration of clinical impact of this improved method of pathology reporting is required for successful introduction and implementation in daily pathology practice. PMID:27097810

  14. Technical progress, the concept of individualized cancer treatment and the innovation of computer-assisted radiotherapy planning

    International Nuclear Information System (INIS)

    After a first step of cancerogenesis, the further development of the tumor is an individual process. At the end of this process the tumor is formed as an individual in the individual. The individuality of cancer exists on the level of organs, tissues and cells and includes an individual tumor-host relationship. Today, optimized cancer treatment requires a most precise biological characterization possible of the tumor and of the tumor-host relationship, which will provide objective information about the individual character of every tumor. Routine analysis and strict therapeutic consideration of the clinical and biological individuality of human cancer can offer real chances for the improvement of cancer treatment. A routine acquisition of individual tumor characteristics will be possible only if methods and equipment are available for the registration of suitable parameters. In this context technical innovations have an essential influence on the realization of the concept of individualized cancer treatment. With the method of flow cytophotometry and other techniques examples are given in how far the ideas of individual cancer management can be realized by introduction of new technical solutions into medical research and clinical practice. Unfortunately there is still a lack of methodology in individualizing cancer treatment. The individualization of radiotherapy is connected to an extremely high degree of technical innovations. Particularly this refers to the topometrical description of the target volume in relation to the adjacent anatomical structures and the body contour as well as the fitting of isodoses to the shape and size of the target volume. As an example of innovation of a technical solution for individual radiotherapy planning the computer-assisted radiotherapy planning system DOPSY is described. (author)

    Advances in DNA sequencing have made genetic testing fast and affordable, but limitations of testing processes are impeding realisation of patient benefits. Ovarian cancer exemplifies the potential value of genetic testing and the shortcomings of current pathways to access testing. Approximately 15% of ovarian cancer patients have a germline BRCA1 or BRCA2 mutation which has substantial implications for their personal management and that of their relatives. Unfortunately, in most countries, routine implementation of BRCA testing for ovarian cancer patients has been inconsistent and largely unsuccessful. We developed a rapid, robust, mainstream genetic testing pathway in which testing is undertaken by the trained cancer team with cascade testing to relatives performed by the genetics team. 207 women with ovarian cancer were offered testing through the mainstream pathway. All accepted. 33 (16%) had a BRCA mutation. The result informed management of 79% (121/154) women with active disease. Patient and clinician feedback was very positive. The pathway offers a 4-fold reduction in time and 13-fold reduction in resource requirement compared to the conventional testing pathway. The mainstream genetic testing pathway we present is effective, efficient and patient-centred. It can deliver rapid, robust, large-scale, cost-effective genetic testing of BRCA1 and BRCA2 and may serve as an exemplar for other genes and other diseases. PMID:27406733

  16. Development And Implementation Of A Strategic Technical Baseline Approach For Nuclear Decommissioning And Clean Up Programmes In The UK

    International Nuclear Information System (INIS)

    The NDA mission as set out within the Energy Act 2004 and stated in the NDA strategy is clear: - 'to deliver a world class programme of safe, cost-effective, accelerated and environmentally responsible decommissioning of the UK's civil nuclear legacy in an open and transparent manner and with due regard to the socio-economic impacts on our communities. Critical to achieving the NDA main objective and overall mission is to accelerate and deliver clean-up programmes through the application of appropriate and innovative technology. The NDA remit also requires us to secure good practice by contractors and carry out and promote research into matters relating to the decommissioning and clean up of nuclear installations and sites. NDA have defined a strategic approach for the underpinning of operational and decommissioning activities where each nuclear site is required to write within the Life Time Plans (LTP) the proposed technical baseline for those activities. This enables the robustness of the activities to be assessed, the gaps and opportunities and accompanying Research and Developments (R and D) requirements to be highlighted and investment to be targeted at key technical issues. NDA also supports the development of a commercial framework where innovation is encouraged and improvements can be demonstrated against the technical baseline. In this paper we will present NDA's overall strategic approach, the benefits already realised and highlight the areas for continued development. In conclusion: The development and implementation of a strategic approach to robustly underpin the technical components of the lifetime plans for operational and decommissioning activities on NDA sites has been extremely successful. As well as showing how mature technology assumptions are and where the key gaps and risks are it has also provided a method for highlighting opportunities to improve on that baseline. The use of a common template across all NDA LTPs has enabled direct comparison

  17. Technical considerations for the implementation of subsurface microbial barriers for restoration of groundwater at UMTRA sites

    International Nuclear Information System (INIS)

    The Uranium Mill Tailings Remediation Action (UMTRA) Program is responsible for the assessment and remedial action at the 24 former uranium mill tailings sites located in the United States. The surface remediation phase, which has primarily focused on containment and stabilization of the abandoned uranium mill tailings piles, is nearing completion. Attention has now turned to the groundwater restoration phase. One alternative under consideration for groundwater restoration at UMTRA sites is the use of in-situ permeable reactive subsurface barriers. In this type of a system, contaminated groundwater will be allowed to flow naturally through a barrier filled with material which will remove hazardous constituents from the water by physical, chemical or microbial processes while allowing passage of the pore water. The subject of this report is a reactive barrier which would remove uranium and other contaminants of concern from groundwater by microbial action (i.e., a microbial barrier). The purpose of this report is to assess the current state of this technology and to determine issues that must be addressed in order to use this technology at UMTRA sites. The report focuses on six contaminants of concern at UMTRA sites including uranium, arsenic, selenium, molybdenum, cadmium and chromium. In the first section of this report, the fundamental chemical and biological processes that must occur in a microbial barrier to control the migration of contaminants are described. The second section contains a literature review of research which has been conducted on the use of microorganisms to immobilize heavy metals. The third section addresses areas which need further development before a microbial barrier can be implemented at an UMTRA site

  18. A criterion-based audit of the technical quality of external beam radiotherapy for prostate cancer

    International Nuclear Information System (INIS)

    Purpose: To evaluate the technical quality of external beam radiotherapy for prostate cancer in Canada. Methods: This was a multi-institution, retrospective study of a random sample of patients undergoing radiotherapy (RT) for prostate cancer in Canada. Patterns of care were determined by abstracting details of the patients’ management from original records. The quality of patient’s technical care was measured against a previously published, comprehensive suite of quality indicators. Results: 32 of the 37 RT centres participated. The total study population of 810 patients included 25% low-risk, 44% intermediate-risk, and 28% high-risk cases. 649 received external beam RT (EBRT) only, for whom compliance with 12 indicators of the quality of pre-treatment assessment ranged from 56% (sexual function documented) to 96% (staging bone scan obtained in high-risk patients). Compliance with treatment-related indicators ranged from 78% (dose to prostate ⩾74 Gy in intermediate risk patients not receiving hormone therapy) to 100% (3DCRT or IMRT plan). Compliance varied among centres; no centre demonstrated 100% compliance on all indicators and every centre was 100% compliant on at least some indicators. The number of assessment-related indicators (n = 13) with which a given centre was 100% compliant ranged from 4 to 11 (median 7) and the number of the treatment-specific indicators (n = 8) with which a given centre was 100% compliant ranged from 6 to 8 (median 8). ADT therapy was utilised in most high-risk cases (191, 92.3%). Conclusions: While patterns of prostate cancer care in Canada vary somewhat, compliance on the majority of quality indicators is very high. However, all centres showed room for improvement on several indicators and few individual patients received care that met target benchmarks on all quality measures. This variation is particularly important for indicators such as delivered dose where impact on disease outcome is known to exist, and suggests that

  1. New technical knowledge to be implemented to the revision of rules on pipe wall thinning management for PWR Plants. 2006 edition

    International Nuclear Information System (INIS)

    Rules for PWR plant pipe wall thinning management were formulated by the Japan Society of Mechanical Engineers in 2006. Since then thinning management of Japanese PWR plants has been carried out based on this rule. Pipe wall thinning phenomena to be dealt with in this rule have been identified in many piping components of power plants. New technical knowledge has been accumulated since the issuance of 2006 edition. We have formulated these knowledge and information about the thinning phenomena in PWR power plants. Given the history of application of this rule, we have to make our best effort to carry out a study of latest technical knowledge and implement them to the revision of rule and improve pipe wall thinning management. This paper summarizes the new technical knowledge and basis to be implemented to the revision of rules on pipe wall thinning management for PWR plants in Japan. (author)

    Full Text Available Abstract Background Management of cancer treatment-related symptoms is an important safety issue given that symptoms can become life-threatening and often occur when patients are at home. With funding from the Canadian Partnership Against Cancer, a pan-Canadian steering committee was established with representation from eight provinces to develop symptom protocols using a rigorous methodology (CAN-IMPLEMENT©. Each protocol is based on a systematic review of the literature to identify relevant clinical practice guidelines. Protocols were validated by cancer nurses from across Canada. The aim of this study is to build an effective and sustainable approach for implementing evidence-informed protocols for nurses to use when providing remote symptom assessment, triage, and guidance in self-management for patients experiencing symptoms while undergoing cancer treatments. Methods A prospective mixed-methods study design will be used. Guided by the Knowledge to Action Framework, the study will involve (a establishing an advisory knowledge user team in each of three targeted settings; (b assessing factors influencing nurses’ use of protocols using interviews/focus groups and a standardized survey instrument; (c adapting protocols for local use, ensuring fidelity of the content; (d selecting intervention strategies to overcome known barriers and implementing the protocols; (e conducting think-aloud usability testing; (f evaluating protocol use and outcomes by conducting an audit of 100 randomly selected charts at each of the three settings; and (g assessing satisfaction with remote support using symptom protocols and change in nurses’ barriers to use using survey instruments. The primary outcome is sustained use of the protocols, defined as use in 75% of the calls. Descriptive analysis will be conducted for the barriers, use of protocols, and chart audit outcomes. Content analysis will be conducted on interviews/focus groups and usability testing

  5. Development of A 32P-Postlabeling Technic for Detection of the Initiation of Cancer

    International Nuclear Information System (INIS)

    It is well know that the interaction between exogenous and also endogenous subs-trances with macromolecular biology (Protein or DNA) in human with in sublethal or lethal level can lead to the initiation of cancer (Auerbach, 1946, Phillips, 1981). In the assessment of carcinogen exposure (exo genus or endo genus), bio markers are chosen based on a knowledge of the internal interactions of carcinogen molecules/metabolites with cellular macromolecules such as DNA, i.e. formation DNA adduct. The 32P-postlabeling assay is most sensitive, fast and applicability methods to structurally diverse classes of chemical. It has been developed to detect DNA adduct (Randerath at. All, 1993, Reddy, 1986). The 32P-Postlabeling technic has emerged as the method of choice for qualitative detection and quantitation of carcinogen-DNA adducts in human. The result of detection of the Adduct will lead the understand of the mechanism reaction of the substance in human organ. The assay of the 32P-Postlabeling involves a stepwise sequence of biochemical reaction entailing: Isolation DNA and following with cleavage by enzymatic hydrolyzed of intact DNA (Nucleotide) with phosphate in 3 position. Attachment of a 32P- label to the 5-hydroxyl end of DNA (Nucleotide) creating a 3,5-biphosphate; following by separation and detection of adducts by high-regulation TLC and autoradiography respectively and quantitation of adducts by measurement of radioactivity. The 32P-Postlabeling was used to detection of DNA adduct of Polycyclic aromatic and alpha, beta unsaturated carbonyl compound such crotonaldehyde, which is in this paper to discussed. We have investigated and developed the 32P-Postlabeling for detection of modified DNA of crotonaldehyde in vitro and in vivo as markers for initiation of cancer. From the result of study were found the adduct the adduct in several organs of F-344 rast after gavage and persisted to a certain extent (Eder dan Budiawan, 1997)

    2012-01-01

    The contemporary problem of prostate cancer overtreatment can be partially attributed to the diagnosis of potentially indolent prostate cancers that pose low risk to aged men,and lack of sufficiently accurate risk stratification methods to reliably seek out men with indolent diseases.Since progressive acquisition and accumulation of genomic alterations,both genetic and epigenetic,is a defining feature of all human cancers at different stages of disease progression,it is hypothesized that RNA and DNA alterations characteristic of indolent prostate tumors may be different from those previously characterized in the setting of clinically significant prostate cancer.Approaches capable of detecting such alterations on a genome-wide level are the most promising.Such analysis may uncover molecular events defining early initiating stages along the natural history of prostate cancer progression,and ultimately lead to rational development of risk stratification methods for identification of men who can safely forego treatment.However,defining and characterizing indolent prostate cancer in a clinically relevant context remains a challenge,particularly when genome-wide approaches are employed to profile formalin-fixed paraffin-embedded (FFPE) tissue specimens.Here,we provide the conceptual basis underlying the importance of understanding indolent prostate cancer from molecular profiling studies,identify the key hurdles in sample acquisition and variables that affect molecular data derived from FFPE tissues,and highlight recent progresses in efforts to address these technical challenges.

  8. Planning and implementing an implanted fiducial programme for prostate cancer radiation therapy

    International Nuclear Information System (INIS)

    Full text: Using implanted gold seeds as fiducial markers to verify the position of the prostate in radiation therapy is well accepted and is becoming the standard of practice and requirement for international multicentre trials. In 2006 the decision was made at the Peter MacCallum Caner Centre (Peter Mac) to plan for and implement this process as standard clinical practice for radical dose prostate treatments (74-78 Gy). Before this, programme verification of field placement for prostate cancer radiation treatment was routinely carried out using regular off-line electronic portal imaging with matching of bony anatomy. A small multidisciplinary team investigated and assisted in the implementation of this new practice across the Peter Mac sites at East Melbourne and our three satellite centres. Issues considered included seed size, number and position in the prostate, implant equipment, imaging equipment and procedure and consent and information forms. The use of a custom made fiducial pack, comprehensive patient information and a daily on-line imaging process was implemented. The experience of the first 28 patients at Peter Mac from January 2007 to May 2007 inclusive is reported on.

  10. First epidemiological analysis of breast cancer incidence and tumor characteristics after implementation of population-based digital mammography screening

    International Nuclear Information System (INIS)

    Purpose: to epidemiologically evaluate the impact of digital mammography screening on incidence rates and tumor characteristics for breast cancer. Materials and methods: the first German digital screening units in the clinical routine were evaluated during the implementation period by using data from the cancer registry to compare the incidence rate of breast cancers and prognostic characteristics. 74% of women aged 50-69 within the region of Muenster/Coesfeld/Warendorf were invited between 10/2005 and 12/2007 for initial screening; 55% participated (n = 35961). Results: in 2002-2004 the average breast cancer incidence rate (per 100000) was 297.9. During the implementation of screening, the rate rose to 532.9 in 2007. Of the 349 cancers detected with screening, 76% (265/349) were invasive compared to 90% (546/608) of cases not detected with screening during the same period. 37% (97/265) of cancers detected in the screening program had a diameter of ≤ 10 mm and 75% (198/265) were node-negative compared to 15% (79/546) and 64% (322/503), respectively, in cancers detected outside the screening program. The distribution of invasive tumor size (pT categories) and the nodal status differed with statistical significance between cancers detected in and outside the program (p = 0.005 and p = 0.004, respectively).

  11. Quality assurance for the clinical implementation of kilovoltage intrafraction monitoring for prostate cancer VMAT

    International Nuclear Information System (INIS)

    Purpose: Kilovoltage intrafraction monitoring (KIM) is a real-time 3D tumor monitoring system for cancer radiotherapy. KIM uses the commonly available gantry-mounted x-ray imager as input, making this method potentially more widely available than dedicated real-time 3D tumor monitoring systems. KIM is being piloted in a clinical trial for prostate cancer patients treated with VMAT (NCT01742403). The purpose of this work was to develop clinical process and quality assurance (QA) practices for the clinical implementation of KIM. Methods: Informed by and adapting existing guideline documents from other real-time monitoring systems, KIM-specific QA practices were developed. The following five KIM-specific QA tests were included: (1) static localization accuracy, (2) dynamic localization accuracy, (3) treatment interruption accuracy, (4) latency measurement, and (5) clinical conditions accuracy. Tests (1)–(4) were performed using KIM to measure static and representative patient-derived prostate motion trajectories using a 3D programmable motion stage supporting an anthropomorphic phantom with implanted gold markers to represent the clinical treatment scenario. The threshold for system tolerable latency is <1 s. The tolerances for all other tests are that both the mean and standard deviation of the difference between the programmed trajectory and the measured data are <1 mm. The (5) clinical conditions accuracy test compared the KIM measured positions with those measured by kV/megavoltage (MV) triangulation from five treatment fractions acquired in a previous pilot study. Results: For the (1) static localization, (2) dynamic localization, and (3) treatment interruption accuracy tests, the mean and standard deviation of the difference are <1.0 mm. (4) The measured latency is 350 ms. (5) For the tests with previously acquired patient data, the mean and standard deviation of the difference between KIM and kV/MV triangulation are <1.0 mm. Conclusions: Clinical process and

  12. Validation and practical implementation of a multidisciplinary cancer distress screening questionnaire

    International Nuclear Information System (INIS)

    Background: In order to identify cancer patients with psychosocial needs during radiotherapy, a routine screening questionnaire is widely recommended in the literature. Several tools focusing mainly on psychological issues have been developed during the past decade. However, problems with their implementation into clinical routine have been repeatedly reported, due to a lack of practicability for clinicians and nurses. This study reports the compilation of a multidisciplinary screening questionnaire and an analysis of the effectiveness of its implementation into clinical routine at the Department of Radiotherapy, Medical University of Vienna. Materials and methods: The screening questionnaire is based on a compilation of several subscales from established and validated assessment tools. It focuses on comprehensive information with high a clinical relevance for all professions. In a pilot study, patients' acceptance was assessed qualitatively. Analysis of missing screening data in consecutively admitted patients reflects the effectiveness of implementation and representativity of the data. A validation analysis of the psychological subscales was performed using external criteria and its internal consistency was tested with Cronbachs' α. Results: Qualitative patient acceptance of the screening questionnaire is good. The overall response rate in the screening procedure was 75 %. Missing patient screening data sets arose randomly - mainly due to organizational problems - and did not result in systematic errors. The psychological subscales identify highly distressed patients with a sensitivity of 89 and 78 %, and an internal consistency of 0.843 and 0.617. Conclusion: The multidisciplinary screening questionnaire compiled in this study has a high patient acceptance, provides reliable and representative data and identifies highly distressed patients with excellent sensitivity. Although requiring additional personnel resources, it can be implemented successfully in

However, problems with their implementation into clinical routine have been repeatedly reported, due to a lack of practicability for clinicians and nurses. This study reports the compilation of a multidisciplinary screening questionnaire and an analysis of the effectiveness of its implementation into clinical routine at the Department of Radiotherapy, Medical University of Vienna. Materials and methods: The screening questionnaire is based on a compilation of several subscales from established and validated assessment tools. It focuses on comprehensive information with high a clinical relevance for all professions. In a pilot study, patients' acceptance was assessed qualitatively. Analysis of missing screening data in consecutively admitted patients reflects the effectiveness of implementation and representativity of the data. A validation analysis of the psychological subscales was performed using external criteria and its internal consistency was tested with Cronbachs' {alpha}. Results: Qualitative patient acceptance of the screening questionnaire is good. The overall response rate in the screening procedure was 75 %. Missing patient screening data sets arose randomly - mainly due to organizational problems - and did not result in systematic errors. The psychological subscales identify highly distressed patients with a sensitivity of 89 and 78 %, and an internal consistency of 0.843 and 0.617. Conclusion: The multidisciplinary screening questionnaire compiled in this study has a high patient acceptance, provides reliable and representative data and identifies highly distressed patients with excellent sensitivity. Although requiring additional personnel resources, it can be implemented

Additionally, we describe how such an ISOA creates potential benefits in informatics education, enhancing utility for creating enduring digital content in this clinical domain. PMID:25392683

  17. An implementation strategy for IMRT of ethmoid sinus cancer with bilateral sparing of the optic pathways

    International Nuclear Information System (INIS)

    Purpose: To develop a protocol for the irradiation of ethmoid sinus cancer, with the aim of sparing binocular vision; of developing a strategy of intensity-modulated radiation therapy (IMRT) planning that produces dose distributions that (1) are consistent with the protocol prescriptions and (2) are deliverable by static segmental IMRT techniques within a 15-minute time slot; of fine tuning the implementation strategy to a class solution approach that is sufficiently automated and efficient, allowing routine clinical application; of reporting on the early clinical implementation involving 11 patients between February 1999 and July 2000. Patients and Methods: Eleven consecutive T1-4N0M0 ethmoid sinus cancer patients were enrolled in the study. For Patients 1-8, a first protocol was implemented, defining a planning target volume prescription dose of 60 to 66 Gy in 30-33 fractions and a maximum dose (Dmax) of 50 Gy to optic pathway structures and spinal cord and limit of 60 Gy to brainstem. For Patients 9-11, an adapted (now considered mature) protocol was implemented, defining a (planning target volume) prescription dose of 70 Gy in 35 fractions and a Dmax to optic pathway structures and brainstem of 60 Gy and to spinal cord of 50 Gy. Results: The class solution-directed strategy developed during this study reduced the protocol translation process from a few days to about 2 hours of planner time. The mature class solution involved the use of 7 beam incidences (20-37 segments), which could be delivered within a 15-minute time slot. Acute side effects were limited and mild. None of the patients developed dry eye syndrome or other visual disturbances. The follow-up period is too short for detection of retinopathy or optic nerve and chiasm toxicity. Conclusion: Conventional radiotherapy of ethmoid sinus tumors is associated with serious morbidity, including blindness. We hypothesize that IMRT has the potential to save binocular vision.

  19. Difficulties encountered and solutions found when implementing stereotactic radiotherapy of non-small cell lung cancer

    International Nuclear Information System (INIS)

    The aim of this paper is to describe the difficulties encountered when implementing stereotactic radiotherapy of non-small cell lung cancer (T1-T2, N0, M0) using a voluntary breath-hold technique. From 25/03/2010 to 22/02/2011, eight patients with a non-small cell lung cancer were selected for treatment. CT images were obtained with the patient maintaining breath-hold using a spirometer. Treatment was delivered when the patient maintains this level of breath-hold. Treatment was performed with a 4 MV and 10 MV photon beams from a linear accelerator Varian 2100CS, equipped with a 120 leaves collimator. 60 Gy or 48 Gy were delivered, in four sessions, to the 80% isodose. The planning target volume (PTV) was defined by adding a 5 mm margin to the internal target volume (ITV), the ITV corresponding to the gross tumour volume (GTV) plus a 3 mm margin. CTV is considered equal to GTV. The non-understanding of the gating technique, the great number of beams and the limited breath-hold times led to the failure of some treatments. It can be explained by some patients insufficient respiratory abilities and the low dose rate of one of the beams used for treatment, thus forcing some radiation fields to be delivered in two or three times. Implementing such a technique can be limited by the patients' physical abilities and the materials used. Some solutions were found: a training phase more intense with a coaching of the breath-hold technique more precise, or the use of an abdominal compression device. (authors)

    With the implementation of the Affordable Care Act (ACA), it is essential for the public health sector to elucidate its role with respect to its mission of assuring population health, and to clarify its role with respect to the private health care system. To that end, we examined the value added to the population health enterprise of successful public-private partnerships (PPPs) such as those found in the Illinois Breast and Cervical Cancer Program (IBCCP), the Centers for Disease Control and Prevention's (CDC's) National Breast and Cervical Cancer Early Detection Program (NBCCEDP) in Illinois. Key Informant (KI) interviews focused on IBCCP implementation were conducted with IBCCP lead agency (LA) program coordinators (n = 35/36) in winter 2012-2013. Analysis was conducted using Atlas.ti software. The KI interviews revealed the existence of highly developed PPPs between the IBCCP LAs and individual medical providers and hospitals across Illinois. The data suggest that the small amount of funding provided by IBCCP to each LA in Illinois has been used to build and sustain robust PPPs in the majority of the IBCCP communities. The PPPs developed through the IBCCP can be seen as an unplanned benefit of CDC's investment in breast and cervical health through the NBCCEDP. While the IBCCP/NBCCEDP might be considered a "boutique" categorical program which some may consider no longer necessary as individuals gain insurance under the ACA, the KI data underscore the critical role of public sector dollars, not only to serve individuals and communities directly but also to mobilize the private health care sector to act in partnership with public entities and become advocates for underserved communities.

    Full Text Available Public education mass media campaigns are an important intervention for influencing behaviour modifications. However, evidence on the effectiveness of such campaigns to encourage the population to reduce sun exposure is limited. This study investigates the benefits and costs of three skin cancer campaigns implemented in New South Wales from 2006-2013. This analysis uses Australian dollars (AUD and 2010-11 as the currency and base year, respectively. Historical data on skin cancer were used to project skin cancer rates for the period 2006-2020. The expected number of skin cancer cases is derived by combining skin cancer rates, sunburn rates and relative risk of skin cancers due to sun exposure. Counterfactual estimates are based on sunburn exposure in the absence of the campaigns. Monetary values are attached to direct (treatment and indirect (productivity costs saved due to fewer skin cancer cases. Monetary benefits are compared with the cost of implementing the campaigns and are presented in the form of a benefit-cost ratio. Relative to the counterfactual (i.e., no campaigns there are an estimated 13,174 fewer skin cancers and 112 averted deaths over the period 2006-2013. The net present value of these benefits is $60.17 million and the campaign cost is $15.63 million. The benefit cost ratio is 3.85, suggesting that for every $1 invested a return of $3.85 is achieved. Skin cancer public education mass media campaigns are a good investment given the likely extent to which they reduce the morbidity, mortality and economic burden of skin cancer.

    A priority translational research objective in cancer medicine is the discovery of novel therapeutic targets for solid tumours. Ideally, co-discovery of predictive biomarkers occurs in parallel to facilitate clinical development of agents and ultimately personalise clinical use. However, the identification of clinically useful predictive biomarkers for solid tumours has proven challenging with many initially promising biomarkers failing to translate into clinically useful applications. In particular, the 'failure' of a predictive biomarker has often only become apparent at a relatively late stage in investigation. Recently, the field has recognised the need to develop a robust clinical biomarker development methodology to facilitate the process. This review discusses the recent progress in this area focusing on the key stages in the biomarker development process: discovery, validation, qualification and implementation. Concentrating on predictive biomarkers for selecting systemic therapies for individual patients in the clinic, the advances and progress in each of these stages in biomarker development are outlined and the key remaining challenges are discussed. Specific examples are discussed to illustrate the challenges identified and how they have been addressed. Overall, we find that significant progress has been made towards a formalised biomarker developmental process. This holds considerable promise for facilitating the translation of predictive biomarkers from discovery to clinical implementation. Further enhancements could eventually be found through alignment with regulatory processes. PMID:20138504

    Despite rising medical costs within the US healthcare system, quality and outcomes are not improving. Without significant policy reform, the cost-quality imbalance will reach unsustainable proportions in the foreseeable future. The rising cost of healthcare in part results from an expanding aging population with an increasing number of life-threatening diseases. This is further compounded by a growing arsenal of high-cost therapies. In no medical specialty is this more apparent than in the area of oncology. Numerous attempts to reduce costs have been attempted, often with limited benefit and brief duration. Because physicians directly or indirectly control or influence the majority of medical care costs, physician behavioral changes must occur to bend the healthcare cost curve in a sustainable fashion. Experts within academia, health policy, and business agree that a significant paradigm change in stakeholder collaboration will be necessary to accomplish behavioral change. Such a collaboration has been pioneered by Blue Cross Blue Shield of Michigan and Physician Resource Management, a highly specialized oncology healthcare consulting firm with developmental and ongoing technical, analytic, and consultative support from Cardinal Health Specialty Solutions, a division of Cardinal Health. We describe a successful statewide collaboration between payers and providers to create a cancer clinical care pathways program. We show that aligned stakeholder incentives can drive high levels of provider participation and compliance in the pathways that lead to physician behavioral changes. In addition, claims-based data can be collected, analyzed, and used to create and maintain such a program. PMID:22694114

    The promise of widespread implementation of efficacious interventions across the cancer continuum into routine practice and policy has yet to be realized. Multilevel influences, such as communities and families surrounding patients or health-care policies and organizations surrounding provider teams, may determine whether effective interventions are successfully implemented. Greater recognition of the importance of these influences in advancing (or hindering) the impact of single-level interventions has motivated the design and testing of multilevel interventions designed to address them. However, implementing research evidence from single- or multilevel interventions into sustainable routine practice and policy presents substantive challenges. Furthermore, relatively few multilevel interventions have been conducted along the cancer care continuum, and fewer still have been implemented, disseminated, or sustained in practice. The purpose of this chapter is, therefore, to illustrate and examine the concepts underlying the implementation and spread of multilevel interventions into routine practice and policy. We accomplish this goal by using a series of cancer and noncancer examples that have been successfully implemented and, in some cases, spread widely. Key concepts across these examples include the importance of phased implementation, recognizing the need for pilot testing, explicit engagement of key stakeholders within and between each intervention level; visible and consistent leadership and organizational support, including financial and human resources; better understanding of the policy context, fiscal climate, and incentives underlying implementation; explication of handoffs from researchers to accountable individuals within and across levels; ample integration of multilevel theories guiding implementation and evaluation; and strategies for long-term monitoring and sustainability.

  6. Modality-dependent dose requirements in the Austrian breast cancer early detection program. First results from technical quality assurance

    International Nuclear Information System (INIS)

    The Austrian Breast Cancer Early Detection Program (BKFP) has officially started in January 2014. In order to ensure that all participating women can rely on a sufficient cancer detection rate while at the same time the required dose is as low as reasonably achievable, all participating radiology institutes (approx. 200) have to fulfill strict quality assurance requirements. The control and certification is performed by the Reference Center for Technical Quality Assurance (RefZQS), which has been developing the methods and tolerances in a pilot project since 2007. The limits are defined in the EUREF-Oeprotocol which is based on the European EPQC guidelines. From the requirement for optimized image quality while simultaneously following the ALARA principle, we found modality-dependent dose requirements, which we had expected but which have now been compiled for the first time for Austria.

    This study examined the benefits of incorporating screening for distress as a routine part of care for patients with head and neck and neurologic cancers in a tertiary cancer center. Using a comparative 2-cohort pre-post implementation sequential design, consecutive outpatients with head and neck and neurologic cancers were recruited into 2 separate cohorts. Cohort 1 included patients attending clinics during April 2010, before the implementation of the screening program. The program was then implemented and patients completed the Screening for Distress Minimum Dataset (the Edmonton Symptom Assessment System [ESAS] and the Canadian Problem Checklist [CPC]) at each clinic visit. Cohort 2 included patients attending clinics during March 2011. Consenting patients completed screening and outcome measures (ESAS, CPC, and either the Functional Assessment of Cancer Therapy-Brain or the Functional Assessment of Cancer Therapy-Head and Neck). A total of 146 patients (78 head and neck and 68 neurologic) provided data for Cohort 1, and 143 (81 head and neck and 62 neurologic) provided data for Cohort 2. Compared with Cohort 1, patients with neurologic cancers in Cohort 2 reported significantly higher scores on the Functional Assessment of Cancer Therapy: General total and emotional quality of life subscale; fewer high scores (≥ 4) on the ESAS breathlessness item; and fewer problems with fears/worries, frustration/anger, finding meaning in life, and worry about friends/family. Head and neck patients in Cohort 2 reported significantly higher emotional quality of life and fewer problems with eating and weight than those in Cohort 1. Although no definitive causal attributions can be made, patients exposed to routine screening for distress reported better well-being and fewer emotional, physical, and practical problems than historical controls.

    The Faja Petrolifera del Orinoco, Venezuela, is the largest accumulation field in the world, extraction is mainly achieved with cold production and recovery factors are around 10%. Thus the implementation of new technologies such as thermal recovery methods is needed to increase oil production through better recovery factors. This study aimed at assessing the technical feasibility of applying the horizontal alternate steam drive (HASD) method which consists of 3 or more parallel horizontal wells acting alternately as injectors and producers. Simulations, sensitivity analyses, uncertainty assessments and optimizations were conducted on a base case of 4 well pad in the Junin 8 block. Parameters influencing the oil recovery factor and the steam oil ratio were found as well as the optimal operational conditions; under those conditions, a recovery factor of more than 30% was observed. This study suggested that HASD could be technically feasible but an economical assessment should be undertaken.

    The development of a Lateral Total Body Irradiation protocol to be implemented at a High Specialty Medical Unit in Mexico as preparatory regimen for bone marrow transplant and treatment of several lymphomas is presented. This protocol was developed following AAPM specifications and has been validated for application at a cancer care center in United States. This protocol fundamentally focuses on patient care, avoiding instability and discomfort that may be encountered by other treatment regimes. In vivo dose verification with TLD-100 chips for each anatomical region of interest was utilized. TLD-100 chips were calibrated using a 6 MV photon beam for 10-120 cGy. Experimental results show TLD measurements with an error less than 1%. Standard deviations for calculated and measured doses for seven patients have been obtained. Data gathered for different levels of compensation indicate that a 3% measured tolerance level is acceptable. TLD point-dose measurements have been used to verify the dose beyond partial transmission lung blocks. Dose measurements beyond the lung block showed variation about 50% respects to prescribe dose. Midplane doses to the other anatomical sites were less than 2.5% respect of the prescribed dose.

    Full Text Available In 2004, a population-based cohort (the Núcleo Mama Porto Alegre - NMPOA Cohort was started in Porto Alegre, southern Brazil and within that cohort, a hereditary breast cancer study was initiated, aiming to determine the prevalence of hereditary breast cancer phenotypes and evaluate acceptance of a genetic cancer risk assessment (GCRA program. Women from that cohort who reported a positive family history of cancer were referred to GCRA. Of the 9218 women enrolled, 1286 (13.9% reported a family history of cancer. Of the 902 women who attended GCRA, 55 (8% had an estimated lifetime risk of breast cancer ³ 20% and 214 (23.7% had pedigrees suggestive of a breast cancer predisposition syndrome; an unexpectedly high number of these fulfilled criteria for Li-Fraumeni-like syndrome (122 families, 66.7%. The overall prevalence of a hereditary breast cancer phenotype was 6.2% (95%CI: 5.67-6.65. These findings identified a problem of significant magnitude in the region and indicate that genetic cancer risk evaluation should be undertaken in a considerable proportion of the women from this community. The large proportion of women who attended GCRA (72.3% indicates that the program was well-accepted by the community, regardless of the potential cultural, economic and social barriers.

    implementation into long-term evolution models. This type of surveillance should not be considered as a way to compensate for the lack of knowledge at a previous stage. Indeed, enough confidence in models and parameters contributing to a safety case will have been acquired, for instance in a URL, prior to authorisation and operation of a repository. Such prior knowledge, however, cannot be tested on the full pre-closure time scale or length scale of a repository. The observation of host rock and repository component evolution provides information to stakeholders throughout the pre closure period. Such added knowledge may contribute to improve stakeholder confidence in the process. It is taken into account to support the decisions pertaining to a step-wise, reversible repository management. For example, it may support a decision for disposal cell closure, it allows evaluating the feasibility of waste retrieval at successive stages of a stepwise closure, and it may contribute to update the design of disposal cells or access drifts yet to be built. Monitoring activities are subject to repository-specific constraints such as: materials must not interfere with operational safety; material must not reduce long term safety significantly; materials must operate under expected environmental conditions. The establishment of monitoring activities will draw on similarities with other systems that are subject to monitoring activities (e.g. monitoring of concrete and clayey structures in dams, steel structures in pipelines, railway tunnels, etc.). The key lessons from those activities point to the importance of the correct interpretation of measurements and the need for redundancy, as well as for pre-testing and careful installation of monitoring equipment. The selection criteria for adequate monitoring methods include safety, robustness and ease of integration in an automatic data acquisition network. Andra outlined a potential and preliminary monitoring strategy, as part of a repository

    IIEC, a division of CERF, has developed an extensive base of experience implementing activities that support climate action by developing USIJI projects in transitional countries within Asia, Latin America, Central and Eastern Europe, and southern Africa. IIEC has been able to provide a range of technical and policy assistance to governments and industry in support of sustainable energy use. IIEC continues to work in key countries with local partners to develop and implement energy efficiency policies and standards, develop site-specific projects, and assist governing bodies to establish national priorities and evaluation criteria for approving GHG-mitigation projects. As part of this project, IIEC focused on promoting a series of activities in Thailand and South Africa in order to identify GHG mitigation projects and work within the national approval process of those countries. The sections of this report outline the activities conducted in each country in order to achieve that goal.

    The African couples HIV testing and counseling (CHTC) model, which focuses on heterosexual couples, was adapted for same-sex male couples in the US. This paper presents the results of a follow-up survey conducted with representatives of the agencies that received CHTC training. The paper aims to understand the post-training implementation and identify critical technical assistance gaps. There are clear needs for continual learning opportunities, focused on the key skills required for CHTC, and for resources aimed at tackling agency-level concerns about service provision and integration. Central to this is the need for implementation science research that can identify the messages that are effective in encouraging couples to utilize CHTC and test models of service integration.

    Many experts on vaccination are convinced that efforts should be made to encourage increased collaboration between National Immunization Technical Advisory Groups on immunization (NITAGs) worldwide. International meetings were held in Berlin, Germany, in 2010 and 2011, to discuss improvement of the methodologies for the development of evidence-based vaccination recommendations, recognizing the need for collaboration and/or sharing of resources in this effort. A third meeting was held in Paris, France, in December 2014, to consider the design of specific practical activities and an organizational structure to enable effective and sustained collaboration. The following conclusions were reached: (i) The proposed collaboration needs a core functional structure and the establishment or strengthening of an international network of NITAGs. (ii) Priority subjects for collaborative work are background information for recommendations, systematic reviews, mathematical models, health economic evaluations and establishment of common frameworks and methodologies for reviewing and grading the evidence. (iii) The programme of collaborative work should begin with participation of a limited number of NITAGs which already have a high level of expertise. The amount of joint work could be increased progressively through practical activities and pragmatic examples. Due to similar priorities and already existing structures, this should be organized at regional or subregional level. For example, in the European Union a project is funded by the European Centre for Disease Prevention and Control (ECDC) with the aim to set up a network for improving data, methodology and resource sharing and thereby supporting NITAGs. Such regional networking activities should be carried out in collaboration with the World Health Organization (WHO). (iv) A global steering committee should be set up to promote international exchange between regional networks and to increase the involvement of less experienced

    The ability of tumors to provoke formation of cancer-associated secondary immunodeficiency (CASID) with predominant suppression of CMI and cancer-associated secondary immunodeficiency with clinical autoimmunity syndrome (CASICAS) with triggering of a set of the autoimmune deviations is appearing to be a key event in the restriction of hosts' anti-tumor immunity. Earlier the existence of the above-mentioned syndromes was demonstrated in BCC and GBM patients. In order to reach a point where immunological phenotypes in GBM and BCC can be clarified clinically and, partly, pathogenically, we have conducted a series of studies of typical and atypical types of immune responsiveness in patients with GBM and BCC. For GBM and BCC three scenarios of the involvement of the immune responsiveness have been established in a series of our studies, i.e., (i) malignancy with no immunopathology, (ii) malignancy as CASID, and (iii) malignancy as CASICAS. All of those scenarios demonstrated significant differences in their immune-mediated manifestations which, in turn, were proven to reveal close associative relationships with a specific clinicopathologic type and clinical manifestations of the tumor. CASID and CASICAS share two common features, i.e., (i) signs of immunodeficiency and (ii) a tandem of the deviations within the adaptive and innate links of the host immune responsiveness. At the same time, CASID and CASICAS are distinct pathogenically and clinically, and in terms of depth of the immune deviations observed, CASID patients manifest a breakage in both links, whereas in CASICAS patients, a breakage in the adaptive link would dominate. To get these differences clarified, we summarized major types of the immune imbalances and sets of clinical and clinicopathologic manifestations to illustrate the above-mentioned features in CASID and CASICAS patients. There are distinct close correlations between clinicopathologic features of the disease course and sets of the immune

    Full Text Available Abstract Background Colorectal cancer (CRC is the most common cancer in Europe with a mortality rate of almost 50%. The prognosis of patients is largely determined by the clinical and pathological stage at the time of diagnosis. Population screening has been shown to reduce CRC-related mortality rate. Most screening programs worldwide rely on fecal immunochemical testing (FIT. The effectiveness of a FIT screening program is not only influenced by initial participation rate, but also by program adherence during consecutive screening rounds. We aim to evaluate the participation rate in and yield of a third CRC screening round using FIT. Methods and design Four years after the first screening round and two years after the second round, a total number of approximately 11,000 average risk individuals (50 to 75 years of age will be invited to participate in a third round of FIT-based CRC screening. We will select individuals in the same target area as in the previous screening rounds, using the electronic database of the regional municipal administration registrations. We will invite all FIT-negatives and all non-participants in previous screening rounds, as well as eligible first time invitees who have moved into the area or have become 50 years of age. FITs will be analyzed in the special technique laboratory of the Academic Medical Center of the University of Amsterdam. All FIT-positives will be invited for a consultation at the outpatient clinic. In the absence of contra-indications, a colonoscopy will follow at the Academic Medical Center or at the Flevohospital. The primary outcome measures are the participation rate, defined as the proportion of invitees that return a FIT in this third round of FIT-screening, and the diagnostic yield of the program. Implications This study will provide precise data on the participation in later FIT screening rounds. This enables to estimate the effectiveness of CRC screening programs that rely on repeated

  9. Technical meeting on lessons learned with respect to SAT implementation, including development of trainers and use of cost effective training methods

    International Nuclear Information System (INIS)

    The past years have brought some significant changes in the world energy market, where the nuclear power plants and utilities are operating. Part of NPPs is privatised now; the electricity markets are liberalized and become more and more international. Due to the increase of competition, the power production costs are now monitored more closely than before. The opening of electricity markets has led the nuclear power plants to be under the serious economic pressure with a demand for continuous cost reduction. All these require from NPPs to make their personnel training more cost-effective. In addition, based on modern technology, a great amount of new training tools, aids and technologies have been introduced during the last 2-3 years, these new opportunities can be quite useful for training cost optimization. On the basis of experience gained worldwide in the application of the systematic approach to training (SAT), SAT based training is now a broad integrated approach emphasizing not only technical knowledge and skills but also human factor related knowledge, skills and attitudes. In this way, all competency requirements for attaining and maintaining personnel competence and qualification can be met, thus promoting and strengthening quality culture and safety culture, which should be fostered throughout the initial and continuing training programmes. The subject of the present technical meeting was suggested by the members of the Technical Working Group on Training and Qualification of NPP Personnel (TWG-T and Q) and supported by a number of the IAEA meetings on NPP personnel training. The technical Meeting on 'Lessons Learned with Respect to SAT Implementation, Including Development of Trainers and Use of Cost Effective Training Methods' was organized by the IAEA in co-operation with the Tecnatom A.S. and was held from 21 to 24 October 2002 in San Sebastian de los Reyes/ Madrid, Spain.

    Inclusion into the programming of inputs of the supervisory algorithm (data collection from the monitoring system, transmission of diagnostic output fro other system and transmission of technological data), of the supervisory process proper based on the data obtained (data analysis) and of the output (presentation of the results to the operator, communication with the master and archiving systems, etc.) requires knowledge of the format of the data transmitted, their availability, communication network protocols, operating system, etc. Hence, the environment for which the algorithm will be developed should be specified, roughly at least. The following topics are addressed: Description of technical means of Czech nuclear power plants (Dukovany, Temelin, Mochovce), and Proposal for technical means to implement the monitoring algorithm (Requirements related to the monitoring systems, Identification of the reference system, Parameters of the selected system). Since no domestic manufacturer of HW for monitoring and diagnostic systems exists, a novel system of the Brueel and Kjaer company for on-line diagnosis and monitoring, COMPASS, was selected as a model model system for the implementation of the supervisory algorithms.

    This article reviews the situation in Switzerland and the provisional implementation-aid published by the Swiss Federal Office of Environment in 2007. This implementation-aid concerns the limits for the magnetic fields produced by electrical installations operated at a voltage of 1 kV and more. The two-working-point model stipulated in the implementation-aid and the design current defined for certain environmental conditions and for a set of cross-sections are discussed. As these conditions hardly ever occur together in real life, calculation programmes and validations for real-life situations are discussed. Real-life conditions are discussed on the basis of a specific example of an overhead power line. The five-step calculation procedure used in the implementation-aid is described in detail. Further topics discussed include power-flow direction and the operation of grid control centres. Calculation examples are provided for the currents, voltages and magnetic fields involved. Finally, several digital calculation methods developed since 1990 are examined.

    2016-01-01

    Screening for lung cancer with low-dose CT has evolved rapidly in recent years since the National Lung Screening Trial (NLST) results. Subsequent professional and governmental organization guidelines have shaped policy and reimbursement for the service. Increasingly available guidance describes eligible patients and components necessary for a high-quality lung cancer screening program; however, practical instruction and implementation experience is not widely reported. We launched a lung cancer screening program in the face of reimbursement and guideline uncertainties at a large academic health center. We report our experience with implementation, including challenges and proposed solutions. Initially, we saw less referrals than expected for screening, and many patients referred for screening did not clearly meet eligibility guidelines. We educated primary care providers and implemented system tools to encourage referral of eligible patients. Moreover, in response to the Centers for Medicare & Medicaid Services (CMS) final coverage determination, we report our programmatic adaptation to meet these requirements. In addition to the components common to all quality programs, individual health delivery systems will face unique barriers related to patient population, available resources, and referral patterns.

    Full Text Available Abstract Background One-half of patients with cancer have pain. In nearly one out of two cancer patients with pain, this was undertreated. Inadequate pain control still remains an important problem in this group of patients. Therefore, in 2008 a national, evidence-based multidisciplinary clinical practice guideline 'pain in patients with cancer' has been developed. Yet, publishing a guideline is not enough. Implementation is needed to improve pain management. An innovative implementation strategy, Short Message Service with Interactive Voice Response (SVS-IVR, has been developed and pilot tested. This study aims to evaluate on effectiveness of this strategy to improve pain reporting, pain measurement and adequate pain therapy. In addition, whether the active role of the patient and involvement of caregivers in pain management may change. Methods/design A cluster randomised controlled trial with two arms will be performed in six oncology outpatient clinics of hospitals in the Southeastern region of the Netherlands, with three hospitals in the intervention and three in the control condition. Follow-up measurements will be conducted in all hospitals to study the long-term effect of the intervention. The intervention includes training of professionals (medical oncologists, nurses, and general practitioners and SMS-IVR to report pain in patients with cancer to improve pain reporting by patients, pain management by medical oncologists, nurses, and general practitioners, and decrease pain intensity. Discussion This innovative implementation strategy with technical tools and the involvement of patients, may enhance the use of the guideline 'pain in patients with cancer' for pain management. Short Message Service alerts may serve as a tool to support self-management of patients. Therefore, the SMS-IVR intervention may increase the feeling of having control over one's life.

  18. Stage distribution of breast cancer diagnosed before and after implementation of population-based mammographic screening

    International Nuclear Information System (INIS)

    Purpose: The German mammographic screening program is very similar to the Norwegian Breast Cancer Screening Program (NBCSP), which started about 10 years earlier. This study analyzes the stage distribution of invasive breast cancers diagnosed in the pre-screening and screening period, and evaluates the overall mortality in women aged 55 - 74 in the pilot and non-pilot counties of the NBCSP. Materials and Methods: The NBCSP invites women aged 50 - 69 to participate in two-view mammography biennially. Chi-square statistics were used to compare percentages of the stage and treatment of invasive breast cancers diagnosed in women residing in the four pilot counties in the pre-screening (1984 - 1995) and screening (1996 - 2007) period. An ecological approach was used to analyze the age-specific mortality in the pilot and non-pilot counties for the period 1970 - 2007. Results: 50 % of the breast cancers diagnosed in the pre-screening period, 70 % of the cases detected with screening, 43 % of the interval cancers, and 52 % of the cancers diagnosed outside the NBCSP were stage I. Stage III + was present in 11 % of the cancers in the pre-screening period, and in 1 % of the cancers detected with screening. In the screening period, the breast cancer mortality rate decreased substantially more in the pilot counties than in the non-pilot counties. Conclusion: The stage distribution of breast cancer diagnosed in the NBCSP is prognostically favorable compared to cancers diagnosed outside the screening program. The reduction in the breast cancer mortality rate was more pronounced in the four pilot counties compared to the non-pilot counties. It is necessary to evaluate the program based on individual data.

  1. Technical Evaluation of the NASA Model for Cancer Risk to Astronauts Due to Space Radiation

    Science.gov (United States)

    2012-01-01

    At the request of NASA, the National Research Council's (NRC's) Committee for Evaluation of Space Radiation Cancer Risk Model reviewed a number of changes that NASA proposes to make to its model for estimating the risk of radiation-induced cancer in astronauts. The NASA model in current use was last updated in 2005, and the proposed model would incorporate recent research directed at improving the quantification and understanding of the health risks posed by the space radiation environment. NASA's proposed model is defined by the 2011 NASA report Space Radiation Cancer Risk Projections and Uncertainties 2010 (Cucinotta et al., 2011). The committee's evaluation is based primarily on this source, which is referred to hereafter as the 2011 NASA report, with mention of specific sections or tables cited more formally as Cucinotta et al. (2011). The overall process for estimating cancer risks due to low linear energy transfer (LET) radiation exposure has been fully described in reports by a number of organizations. They include, more recently: (1) The "BEIR VII Phase 2" report from the NRC's Committee on Biological Effects of Ionizing Radiation (BEIR) (NRC, 2006); (2) Studies of Radiation and Cancer from the United Nations Scientific Committee on the Effects of Atomic Radiation (UNSCEAR, 2006), (3) The 2007 Recommendations of the International Commission on Radiological Protection (ICRP), ICRP Publication 103 (ICRP, 2007); and (4) The Environmental Protection Agency s (EPA s) report EPA Radiogenic Cancer Risk Models and Projections for the U.S. Population (EPA, 2011). The approaches described in the reports from all of these expert groups are quite similar. NASA's proposed space radiation cancer risk assessment model calculates, as its main output, age- and gender-specific risk of exposure-induced death (REID) for use in the estimation of mission and astronaut-specific cancer risk. The model also calculates the associated uncertainties in REID. The general approach for

  2. Technical basis for implementing the use of the PCM-1B for personnel releases at tank farms

    International Nuclear Information System (INIS)

    Currently, Tanks Farms Transition Projects require personnel to perform a whole body survey with portable survey instrumentation prior to entering an automated counting system capable of performing a whole body survey. This practice is redundant since automated whole body survey devices are, in most cases, more sensitive and are less likely to be used incorrectly than portable instrumentation. Additionally, Article 221.2 of the Hanford Site Radiological Control Manual (HSRCM-1) states ''Monitoring for contamination should be performed using frisking equipment that under laboratory conditions can detect total contamination of at least the values specified in Table 2-2.'' Based on this criteria implementing the use of an automated whole body survey device would save significant time, money and reduce the current crowding and potential loss of contamination control that now occurs during peak times at step off pads. This document describes implementation process for applying PCM-1B instruments to perform personnel release surveys

    Background Parental cancer has a significant impact on minor children and families. Psychosocial interventions for affected families can provide support where necessary. This systematic review aims at providing an overview of existing interventions and support programs and focuses on the systematic investigation of barriers and facilitators for using psychosocial interventions for families affected by parental cancer (PROSPERO; registration number CRD42014013020). Methods A search of five electronic databases (EMBASE, MEDLINE, PsycInfo, Psyndex, CINAHL) was conducted in June 2014, and updated in September 2015. We included any kind of studies reporting psychosocial support services or interventions for families affected by parental cancer. Study quality was assessed using the Mixed Method Assessment Tool. Narrative synthesis and thematic analyses were undertaken to examine the included interventions and to identify barriers and facilitators for use and implementation. Results A total of 36 studies covering 19 interventions and support services were included in the systematic review. Interventions focused on children, parents or several family members and analyses revealed a broad picture of theoretical background and primary aims. Several studies focused on developmental or implementation phases or descriptions of interventions. Other included studies reported results of evaluations using qualitative and quantitative methods. Results suggest that interventions are helpful and that participants improved in various outcomes. The thematic analyses indicate that barriers for use of support services refer to aspects concerning the patients and families, such as practical difficulties, perceived need for support or fear of stigma. Cancer patients who understood the need and benefit of support services may have used them more often. Additionally, intervention characteristics such as a flexible structure and accessibility were important to reach families affected by

  6. Study of technical and economical feasibility for implementation of a movable unit for treatment of industrial effluents with electron beam

    International Nuclear Information System (INIS)

    The treatment of industrial effluents is a practice that is disseminating in accelerated rhythm, of contributing to reinforce the public image, through the combat of the pollution, it brings economical advantages allowing the companies the reuse of the treated water in their own processes. The liquid effluent treatment technique studied in the present work is the one that uses the chemical oxidation/reduction standing out the use of the electron beam (e.b.) radiation. This technique uses an advanced oxidation process, generating radicals highly reagents that provoke the oxidation, reduction, dissociation and degradation in composed organic and exercising lethal effect in general in the microorganisms and parasites. In this work a conceptual and basic project of a movable unit of effluents treatment using electron beam radiation process was developed, in order that the unit moves until the treatment point, where the effluent is produced, facilitating the logistics. A technical and economical feasibility study was also elaborated allowing data on the capacity and cost of effluents processing to consolidate the values of the necessary investments to be presented to foundations organs for the construction of a movable unit. The results of the studies demonstrated that it is technically viable attending the pertinent legislation of Brazil, in the aspects of Radiation Protection and transport limit capacity. The unitary cost of the e.b. radiation processing in the movable unit was shown more expensive than in the fixed unit, the reason is the decrease of the efficiency of the interaction of the incident electrons in the effluent, due to the reduction of electron energy operation time of the unit.

    IMRT and VMAT have been widely implemented on breast cancer and NPC cases. Dose verification was conducted to ensure the comparison between dose delivered and prescribe dose in TPS to obtain optimal results and the dose delivered. The gafchromic films measurement was done for breast and NPC simulation on RANDO Phantom, irradiating film by 6 MV photon with 200 cGy and scanned with EPSON V700 using 72 dpi. Dose distribution was calculated using the MATLAB-based in-house algorithm. In order to evaluate the gamma index, gafchromic films and MatriXX 2D array were placed in the Multi Cube and irradiated with EPID in same position. Dose distribution differences for IMRT and VMAT with modalities to TPS on film was 5.34% and 6.68% for NPC PTV70; 12.81% and 6.15% for NPC PTV50; 11.14% and 10.80% for breast cancer. Gamma index differences on IMRT with modalities to MatriXX 2D array and EPID was -0.09% and 5.13% for NPC; 0.51% and 2.28% for breast cancer. On the other hand, gamma index difference on VMAT was -1.65% and 1.43% for NPC; 0.19% and 4.38% for breast cancer. This measurement method can be used to verify dose for breast cancer and NPC cases in IMRT and VMAT.

    Full Text Available Background: Recent studies indicate neoadjuvant chemotherapy (NACT can result in R0 resection in a substantial proportion of patients with technically unresectable oral cavity cancers. However, data regarding the efficacy and safety of docetaxel, cisplatin and 5 fluorouracil (TPF NACT in our setting is lacking. The present audit was proposed to evaluate the toxicities encountered during administration of this regimen. It was hypothesized that TPF NACT would be considered feasible for routine administration if an average relative dose intensity (ARDI of ≥0.90 or more in at least 70% of the patients. Materials and Methods: Technically unresectable oral cancers with Eastern Cooperative Oncology Group PS 0-2, with biopsy proven squamous cell carcinoma underwent two cycles of NACT with TPF regimen. Toxicity and response rates were noted following the CTCAE 4.03 and RECIST criteria. Descriptive analysis of completion rates (completing 2 cycles of planned chemotherapy with ARDI of 0.85 or more, reason for delay, toxicity, and response are presented. Results: The NACT was completed by all patients. The number of subjects who completed all planned cycles of chemotherapy are with the ARDI of the delivered chemotherapy been equal to or >0.85 was 11 (91.67%. All toxicity inclusive Grade 3-5 toxicity was seen in 11 patients (91.67%. The response rate of chemotherapy was 83.33%. There were three complete response, seven partial response, and two stable disease seen post NACT in this study. Conclusion: Docetaxel, cisplatin and 5 fluorouracil regimen can be routinely administered at our center with the supportive care methods and precautionary methods used in our study.

  9. PNNL Technical Support to The Implementation of EMTA and EMTA-NLA Models in Autodesk® Moldflow® Packages

    Under the Predictive Engineering effort, PNNL developed linear and nonlinear property prediction models for long-fiber thermoplastics (LFTs). These models were implemented in PNNL’s EMTA and EMTA-NLA codes. While EMTA is a standalone software for the computation of the composites thermoelastic properties, EMTA-NLA presents a series of nonlinear models implemented in ABAQUS® via user subroutines for structural analyses. In all these models, it is assumed that the fibers are linear elastic while the matrix material can exhibit a linear or typical nonlinear behavior depending on the loading prescribed to the composite. The key idea is to model the constitutive behavior of the matrix material and then to use an Eshelby-Mori-Tanaka approach (EMTA) combined with numerical techniques for fiber length and orientation distributions to determine the behavior of the as-formed composite. The basic property prediction models of EMTA and EMTA-NLA have been subject for implementation in the Autodesk® Moldflow® software packages. These models are the elastic stiffness model accounting for fiber length and orientation distributions, the fiber/matrix interface debonding model, and the elastic-plastic models. The PNNL elastic-plastic models for LFTs describes the composite nonlinear stress-strain response up to failure by an elastic-plastic formulation associated with either a micromechanical criterion to predict failure or a continuum damage mechanics formulation coupling damage to plasticity. All the models account for fiber length and orientation distributions as well as fiber/matrix debonding that can occur at any stage of loading. In an effort to transfer the technologies developed under the Predictive Engineering project to the American automotive and plastics industries, PNNL has obtained the approval of the DOE Office of Vehicle Technologies to provide Autodesk, Inc. with the technical support for the implementation of the basic property prediction models of EMTA and

  10. Technical guidelines for head and neck cancer IMRT on behalf of the Italian association of radiation oncology - head and neck working group

    International Nuclear Information System (INIS)

    Performing intensity-modulated radiotherapy (IMRT) on head and neck cancer patients (HNCPs) requires robust training and experience. Thus, in 2011, the Head and Neck Cancer Working Group (HNCWG) of the Italian Association of Radiation Oncology (AIRO) organized a study group with the aim to run a literature review to outline clinical practice recommendations, to suggest technical solutions and to advise target volumes and doses selection for head and neck cancer IMRT. The main purpose was therefore to standardize the technical approach of radiation oncologists in this context. The following paper describes the results of this working group. Volumes, techniques/strategies and dosage were summarized for each head-and-neck site and subsite according to international guidelines or after reaching a consensus in case of weak literature evidence

    The increasing use of moderate (<35 fractions) and extreme (<5 fractions) hypofractionated radiation therapy in prostate cancer is yielding favorable results, both in terms of maintained biochemical response and toxicity. Several hypofractionation (HF) schemes for the treatment of prostate cancer are available, although there is considerable variability in the techniques used to manage intra-/interfraction motion and deliver radiation doses. We performed a review of the published studies on HF regimens as a topic of interest for the Stereotactic Ablative Radiotherapy working group, which is part of the Italian Association of Medical Physics. Aspects of organ motion management (imaging for contouring, target volume definition, and rectum/bladder preparation) and treatment delivery (prostate localization, image guided radiation therapy strategy and frequency) were evaluated and categorized to assess outcome relative to disease control and toxicity. Despite the heterogeneity of the data, some interesting trends that emerged from the review might be useful in identifying an optimum HF strategy.

  15. Radiotherapy Technical Considerations in the Management of Locally Advanced Pancreatic Cancer: American-French Consensus Recommendations

    International Nuclear Information System (INIS)

    Summary: Pancreatic carcinoma is a leading cause of cancer-related mortality. Approximately 30% of pancreatic cancer patients present with locally advanced, unresectable nonmetastatic disease. For these patients, two therapeutic options exist: systemic chemotherapy or chemoradiotherapy. Within this context, the optimal technique for pancreatic irradiation is not clearly defined. A search to identify relevant studies was undertaken using the Medline database. All Phase III randomized trials evaluating the modalities of radiotherapy in locally advanced pancreatic cancer were included, as were some noncontrolled Phase II and retrospective studies. An expert panel convened with members of the Radiation Therapy Oncology Group and GERCOR cooperative groups to review identified studies and prepare the guidelines. Each member of the working group independently evaluated five endpoints: total dose, target volume definition, radiotherapy planning technique, dose constraints to organs at risk, and quality assurance. Based on this analysis of the literature, we recommend either three-dimensional conformal radiation therapy or intensity-modulated radiation therapy to a total dose of 50 to 54 Gy at 1.8 to 2 Gy per fraction. We propose gross tumor volume identification to be followed by an expansion of 1.5 to 2 cm anteriorly, posteriorly, and laterally, and 2 to 3 cm craniocaudally to generate the planning target volume. The craniocaudal margins can be reduced with the use of respiratory gating. Organs at risk are liver, kidneys, spinal cord, stomach, and small bowel. Stereotactic body radiation therapy should not be used for pancreatic cancer outside of clinical trials. Radiotherapy quality assurance is mandatory in clinical trials. These consensus recommendations are proposed for use in the development of future trials testing new chemotherapy combinations with radiotherapy. Not all of these recommendations will be appropriate for trials testing radiotherapy dose or dose

    2009-01-01

    Cancer survivor numbers in Ireland are increasing due to the success of modern treatments. Although most survivors have a good quality of life not all survivors return to \\'normal\\' after treatment. The HSE funded CANSURVIVOR research project has found that many survivors have difficulties and need help to recover and adjust after cancer treatment. Over a number of exploratory studies using interviews, focus groups and a survey of 262 breast, prostate, colorectal and lung cancer survivors, the researchers found that over 25% of survivors experienced significant difficulties with physical, emotional and social functioning, including symptoms such as insomnia and fatigue, while 33% experienced high levels of anxiety. Of particular concern were the findings that over 50% of survivors were overweight, 35% had reduced their physical activity levels and 13% continued to smoke after cancer, putting them at risk for further health problems. This evidence led to the development of an 8-week multi-disciplinary pilot rehabilitation programme. Significant quality of life improvements were achieved with increases in strength and fitness as well as a reduction in anxiety levels and dietary improvements. The researchers highlight the need for a structured, co-ordinated survivorship service, education of health professionals about survivorship and the provision of high quality information to survivors. This research was led by the School of Psychology at UCD in collaboration with the Physiotherapy and Nutrition departments of St. Vincent\\'s hospital.

    This paper diagnoses the implementation of a new engineering course entitled 'school-based learning (SBL) to work-based learning (WBL) transition module' in the Bahrain Technical and Vocational Education (TVE) learning environment. The module was designed to incorporate an innovative education and training approach with a variety of learning activities that are included in various learning case studies. Each case study was based on with learning objectives coupled with desired learning outcomes. The TVE students should meet the desired outcomes after the completion of the learning activities and assessments. To help with the implementation phase of the new module, the authors developed guidelines for each case study. The guidelines incorporated learning activities to be delivered in an integrated learning environment. The skills to be transferred were related to cognitive, affective, and technical proficiencies. The guidelines included structured instructions to help students during the learning process. In addition, technology was introduced to improve learning effectiveness and flexibility. The guidelines include learning indicators for each learning activity and were based on their interrelation with competencies to be achieved with respect to modern industrial requirements. Each learning indicator was then correlated against the type of learning environment, teaching and learning styles, examples of mode of delivery, and assessment strategy. Also, the learning activities were supported by technological features such as discussion forums for social perception and engagement and immediate feedback exercises for self-motivation. Through the developed module, TVE teachers can effectively manage the teaching and learning process as well as the assessment strategy to satisfy students' individual requirements and enable them to meet workplace requirements.

    A series of specific clinical practice guidelines (CPGs) were published in Canada in 1998. A primary objective of these ‘Clinical Practice Guidelines for the Care and Treatment of Breast Cancer’ was to decrease the variation in breast cancer care across the country. Prior to this, researchers found moderate compliance with consensus recommendations for breast cancer therapies in several Canadian provinces. However, a recent study concluded that the publication of the Canadian CPGs did not red...

    2012-01-01

    Full Text Available Background. Women over 70 with breast cancer have poorer one-year survival and present at a more advanced stage than younger women. Promoting early symptomatic presentation in older women may reduce stage cost effectively and is unlikely to lead to overdiagnosis. After examining efficacy in a randomised controlled trial, we piloted a brief health professional-delivered intervention to equip women to present promptly with breast symptoms, as an integral part of the final invited mammogram at age ~70, in the English National Health Service Breast Screening Programme. Methods. We trained mammographers, who then offered the intervention to older women in four breast screening services. We examined breast cancer awareness at baseline and one month in women receiving the intervention, and also in a service where the intervention was not offered. Results. We trained 27 mammographers to deliver the intervention confidently to a high standard. Breast cancer awareness increased 7-fold at one month in women receiving the intervention compared with 2-fold in the comparison service (odds ratio 15.2, 95% confidence interval 10.0 to 23.2. Conclusions. The PEP Intervention can be implemented in routine clinical practice with a potency similar to that achieved in a randomised controlled trial. It has the potential to reduce delay in diagnosis for breast cancer in older women.

    Heavy fractions resulting from mechanical treatment stages of mechanical-biological waste treatment plants are posing very specific demands with regard to further treatment (large portions of inert and high-caloric components). Based on the current Austrian legal situation such a waste stream cannot be landfilled and must be thermally treated. The aim of this research was to evaluate if an inert fraction generated from this waste stream with advanced separation technologies, two sensor-based [near-infrared spectroscopy (NIR), X-ray transmission (XRT)] and two mechanical systems (wet and dry) is able to be disposed of. The performance of the treatment options for separation was evaluated by characterizing the resulting product streams with respect to purity and yield. Complementing the technical evaluation of the processing options, an assessment of the economic and global warming effects of the change in waste stream routing was conducted. The separated inert fraction was evaluated with regard to landfilling. The remaining high-caloric product stream was evaluated with regard to thermal utilization. The results show that, in principal, the selected treatment technologies can be used to separate high-caloric from inert components. Limitations were identified with regard to the product qualities achieved, as well as to the economic expedience of the treatment options. One of the sensor-based sorting systems (X-ray) was able to produce the highest amount of disposeable heavy fraction (44.1%), while having the lowest content of organic (2.0% C biogenic per kg waste input) components. None of the high-caloric product streams complied with the requirements for solid recovered fuels as defined in the Austrian Ordinance on Waste Incineration. The economic evaluation illustrates the highest specific treatment costs for the XRT (€ 23.15 per t), followed by the NIR-based sorting system (€ 15.67 per t), and the lowest costs for the air separation system (€ 10.79 per t

    Metformin is the most widely used hypoglycemic agent. Besides its conventional indications, increasing evidence demonstrate a potential efficacy of this biguanide as an anticancer drug. Possible mechanisms of actions seem to be independent from its hypoglycemic effect and seemto involve the interference with key pathways in cellular proliferation and glycolysis. To date, many clinical trials implying the use of metformin in cancer treatment are on-going. The increasing use of 18F-2-fluoro-2-deoxyd-glucose positron emission tomography(FDG-PET) in cancer evaluation raises a number of questions about the possible interference of the biguanide on FDG distribution. In particular, the interferences exerted by metformin on AMP-activated protein kinase pathway(the cellular energy sensor), on insulin levels and on Hexokinase could potentially have repercussion on glucose handling and thus on FDG distribution. A better comprehension of the impact of metformin on FDG uptake is needed in order to optimize the use of PET in this setting. This evaluation would be useful to ameliorate scans interpretation in diabetic patients under chronic metformin treatment and to critically interpret images in the context of clinical trials. Furthermore, collecting prospective data in this setting would help to verify whether FDG-PET could be a valid tool to appreciate the anticancer effect of this new therapeutic approach.

    Purpose/Objective: New national guidelines (GL) for radiotherapy (RT) of head and neck cancer (HNC) were implemented at the beginning of 2013. One purpose of the new GL was to nationally standardise the expansion from GTV to high risk CTV (CTV1). This standardisation has resulted in change...... of volume of CTV1 for most institutions which previously used different margins. Change in CTV1 volume definition could influence the risk and time evolution of adverse effects e.g. mucositis. This study investigates change in acute response during RT in a centre where GTV to CTV1 margin was increased from...

  4. Trends in breast cancer mortality in Sweden before and after implementation of mammography screening.

    Directory of Open Access Journals (Sweden)

    Jari Haukka

    Full Text Available BACKGROUND: Incidence-based mortality modelling comparing the risk of breast cancer death in screened and unscreened women in nine Swedish counties has suggested a 39% risk reduction in women 40 to 69 years old after introduction of mammography screening in the 1980s and 1990s. OBJECTIVE: We evaluated changes in breast cancer mortality in the same nine Swedish counties using a model approach based on official Swedish breast cancer mortality statistics, robust to effects of over-diagnosis and treatment changes. Using mortality data from the NordCan database from 1974 until 2003, we estimated the change in breast cancer mortality before and after introduction of mammography screening in at least the 13 years that followed screening start. RESULTS: Breast mortality decreased by 16% (95% CI: 9 to 22% in women 40 to 69, and by 11% (95% CI: 2 to 20% in women 40 to 79 years of age. DISCUSSION: Without individual data it is impossible to completely separate the effects of improved treatment and health service organisation from that of screening, which would bias our results in favour of screening. There will also be some contamination of post-screening mortality from breast cancer diagnosed prior to screening, beyond our attempts to adjust for delayed benefit. This would bias against screening. However, our estimates from publicly available data suggest considerably lower benefits than estimates based on comparison of screened versus non-screened women.

    This study reports clinical performance in the sparing of infrahyoid swallowing organs at risk (SWOARs) in oropharynx cancer intensity-modulated radiation therapy (IMRT) plans. Rates of meeting dose-volume planning goals are reported and compared with geometry-based estimates of what is achievable. This study also develops 3 measures of target-SWOAR geometry and tests their usefulness in providing geometry-based dose-volume planning goals. A total of 50 oropharynx cancer IMRT plans were reviewed. Success rates in meeting institutional dose-volume goals were determined for the glottic larynx (G), postcricoid pharynx (P), and esophagus (E). The following 3 measures of target-SWOAR geometry were investigated as methods of identifying geometry-based planning goals: presence of gross disease in neck levels 3 to 4, target-SWOAR overlap, and a 3-dimensional (3D) measure of target-SWOAR geometry. Locally advanced disease was predominant in this patient population with target volumes overlapping SWOARs in 68% to 98% of cases. Clinical rates of success in meeting dose-volume goals varied by SWOAR (16% to 82%) but compared well with estimated potentially achievable rates in most cases (14% average difference between clinical and potential). Cases grouped by the presence of levels 3 to 4 neck nodes or target-SWOAR overlap did not have significantly different SWOAR doses. Cases grouped using a 3D measure of target-SWOAR geometry differed significantly, providing useful geometry-based planning goals (e.g., mean Glottis dose <45 Gy was achieved 19%, 44%, or 81% of the time in each of 3 groups). This study describes the technical challenge of sparing SWOARs and investigates several potential methods for grouping cases to assist with treatment plan evaluation. Quantifying the 3-D relationship between the targets and SWOARs is a promising way of approaching this complex problem. Data presented in this paper may be useful to evaluate treatment plans using objective geometry

In an ideal world, specific recovery measures would be identified and implemented based on a series of complementary research investigations to definitively identify the proximate causes and specific mechanisms of recruitment failure. The acute status of Kootenai sturgeon and current inability to compartmentalize the complex ecosystem do not afford the luxury of time for exhaustive research studies on every potential mechanism of recruitment failure. Mechanistic studies cannot replace the need for experimental evaluations of implemented adaptive management experiments.

  10. Technical factors associated with radiation pneumonitis after local ± regional radiation therapy for breast cancer

    International Nuclear Information System (INIS)

    Purpose: To assess the incidence of, and clinical factors associated with, symptomatic radiation pneumonitis (RP) after tangential breast/chest wall irradiation with or without regional lymph node treatment. Methods and Materials: The records of 613 patients irradiated with tangential photon fields for breast cancer with >6 months follow-up were reviewed. Clinically significant RP was defined as the presence of new pulmonary symptoms requiring steroids. Data on clinical factors previously reported to be associated with RP were collected, e.g., tamoxifen or chemotherapy exposure and age. The central lung distance (CLD) and the average of the superior and inferior mid lung distance (ALD) in the lateral tangential field were measured on simulator films as a surrogate for irradiated lung volume. Many patients were treated with partly wide tangential fields that included a heart block shielding a part of the lower lung. Results: RP developed in 15/613 (2.4%) patients. In the univariate analysis, there was an increased incidence of RP among patients treated with local-regional radiotherapy (RT) (4.1%) vs. those receiving local RT only (0.9%) (p=0.02), and among patients receiving chemotherapy (3.9%) vs. those not treated with chemotherapy (1.4%) (p=0.06). According to multivariate analysis, only the use of nodal RT remained independently associated with RP (p=0.03). There was no statistically significant association between ranked CLD or ALD measurements and RP among patients treated with nodal irradiation with tangential beams. However, there was a statistically nonsignificant trend for increasing rates of RP with grouped ALD values: below 2 cm (4% RP rate), between 2 and 3 cm (6%), and above 3 cm (14%). Conclusions: RP was an uncommon complication, both with local and local-regional RT. The addition of regional lymph node irradiation slightly increased the incidence of RP among patients treated with the partly wide tangential field technique. Concern for RP should

  11. The validation and clinical implementation of BRCAplus: a comprehensive high-risk breast cancer diagnostic assay.

    Full Text Available Breast cancer is the most commonly diagnosed cancer in women, with 10% of disease attributed to hereditary factors. Although BRCA1 and BRCA2 account for a high percentage of hereditary cases, there are more than 25 susceptibility genes that differentially impact the risk for breast cancer. Traditionally, germline testing for breast cancer was performed by Sanger dideoxy terminator sequencing in a reflexive manner, beginning with BRCA1 and BRCA2. The introduction of next-generation sequencing (NGS has enabled the simultaneous testing of all genes implicated in breast cancer resulting in diagnostic labs offering large, comprehensive gene panels. However, some physicians prefer to only test for those genes in which established surveillance and treatment protocol exists. The NGS based BRCAplus test utilizes a custom tiled PCR based target enrichment design and bioinformatics pipeline coupled with array comparative genomic hybridization (aCGH to identify mutations in the six high-risk genes: BRCA1, BRCA2, PTEN, TP53, CDH1, and STK11. Validation of the assay with 250 previously characterized samples resulted in 100% detection of 3,025 known variants and analytical specificity of 99.99%. Analysis of the clinical performance of the first 3,000 BRCAplus samples referred for testing revealed an average coverage greater than 9,000X per target base pair resulting in excellent specificity and the sensitivity to detect low level mosaicism and allele-drop out. The unique design of the assay enabled the detection of pathogenic mutations missed by previous testing. With the abundance of NGS diagnostic tests being released, it is essential that clinicians understand the advantages and limitations of different test designs.

    The prospective surveillance model proposes a paradigm shift in the delivery of care for patients with breast cancer. The model is based on clinical research and clinical practice experience that was reviewed and discussed at a multidisciplinary meeting. The model identifies critical physical sequelae of treatment as well as timeframes for identification of and surveillance for these issues. Although the model of ongoing assessment for physical impairment and early rehabilitative intervention creates a framework for care, broad support and active dissemination among a variety of stakeholders will be required to transform patient care. Translating research findings to transform practice often occurs on a protracted timeline. The authors sought participation from a variety of stakeholder representatives throughout the process of creating this model in an effort to ensure that it reflects the realities of the patient experience and care delivery, to incorporate their input regarding the construct and viability of the model, and to potentiate effective and efficient strategies for implementation. This article summarizes comments from stakeholder representatives concerning the prospective surveillance model for rehabilitation for women treated for breast cancer. Concerns addressed include the scope of impairments included in the model, the potential creation of barriers to exercise and participation in community exercise programs, and cost and feasibility issues. Stakeholder disseminations strategies are also presented. Overall, there is recognition by the stakeholder group that this model calls attention to important unmet needs and defines a crucial opportunity to improve care for breast cancer survivors.

  13. Clinical care and technical recommendations for 90yttrium microsphere treatment of liver cancer

    International Nuclear Information System (INIS)

    Selective internal radiation therapy (SIRT) with 90yttrium microspheres is a relatively new clinical modality for treating non-resectable malignant liver tumours. This interventional radiology technique employs percutaneous microcatheterisation of the hepatic arterial vasculature to selectively deliver radioembolic microspheres into neoplastic tissue. SIRT results in measurable tumour responses or delayed disease progression in the majority of eligible patients with hepatocellular carcinoma or hepatic metastases arising from colorectal cancer. It has also been successfully used as palliative therapy for non-colorectal malignancies metastatic to the liver. Although most adverse events are mild and transient, SIRT also carries some risks for serious and – rarely – fatal outcomes. In particular, entry of microspheres into non-target vessels may result in radiation-induced tissue damage, such as severe gastric ulceration or radiation cholecystitis. Radiation-induced liver disease poses another significant risk. By careful case selection, considered dose calculation and meticulous angiographic technique, it is possible to minimise the incidence of such complications to less than 10% of all treatments. As the number of physicians employing SIRT expands, there is an increasing need to consolidate clinical experience and expertise to optimise patient outcomes. Authored by a panel of clinicians experienced in treating liver tumours via SIRT, this paper collates experience in vessel mapping, embolisation, dosimetry, microsphere delivery and minimisation of non-target delivery. In addition to these clinical recommendations, the authors propose institutional criteria for introducing SIRT at new centres and for incorporating the technique into multidisciplinary care plans for patients with hepatic neoplasms.

    Molecular diagnostics in cancer pharmacogenomics is indispensable for making targeted therapy decisions especially in lung cancer. For routine clinical practice, the flexible testing platform and implemented quality system are important for failure rate and turnaround time (TAT) reduction. We established and validated the multiplex EGFR testing by MALDI-TOF MS according to ISO15189 regulation and CLIA recommendation in Taiwan. Totally 8,147 cases from Aug-2011 to Jul-2015 were assayed and statistical characteristics were reported. The intra-run precision of EGFR mutation frequency was CV 2.15% (L858R) and 2.77% (T790M); the inter-run precision was CV 3.50% (L858R) and 2.84% (T790M). Accuracy tests by consensus reference biomaterials showed 100% consistence with datasheet (public database). Both analytical sensitivity and specificity were 100% while taking Sanger sequencing as the gold-standard method for comparison. EGFR mutation frequency of peripheral blood mononuclear cell for reference range determination was 0.002 ± 0.016% (95% CI: 0.000–0.036) (L858R) and 0.292 ± 0.289% (95% CI: 0.000–0.871) (T790M). The average TAT was 4.5 working days and the failure rate was less than 0.1%. In conclusion, this study provides a comprehensive report of lung cancer EGFR mutation detection from platform establishment, method validation to clinical routine practice. It may be a reference model for molecular diagnostics in cancer pharmacogenomics. PMID:27480787

    The Forsyth County Cervical Cancer Prevention Project (FCP) is a community-based health education project funded by the National Cancer Institute. The target population includes around 25 000 black women age 18 and older who reside in Forsyth County, North Carolina. The overall goal of the program is to prevent mortality from cervical cancer by promoting Pap smears and return for follow-up care when needed. Based on the principles of social marketing, a plan to reach the target population with mass media educational messages through electronic and print channels was developed. Guided by marketing objectives, the target population was divided into relatively discrete segments. The segments included church attenders, patients in waiting rooms of public and selected health providers, female students at local colleges, shoppers, viewers of radio and television, newspaper readers, and business owners and managers. Introduction of the program was based on strategies developed for reaching the target population in each segment with television, radio and print mass media messages. Qualitative assessment of the mass media developed by the program indicated that all forms of communication helped to increase awareness of the program. PMID:10148691

    An urgent need remains for new paediatric oncology drugs to cure children who die from cancer and to reduce drug-related sequelae in survivors. In 2007, the European Paediatric Regulation came into law requiring industry to create paediatric drug (all types of medicinal products) development programmes alongside those for adults. Unfortunately, paediatric drug development is still largely centred on adult conditions and not a mechanism of action (MoA)-based model, even though this would be more logical for childhood tumours as these have much fewer non-synonymous coding mutations than adult malignancies. Recent large-scale sequencing by International Genome Consortium and Paediatric Cancer Genome Project has further shown that the genetic and epigenetic repertoire of driver mutations in specific childhood malignancies differs from more common adult-type malignancies. To bring about much needed change, a Paediatric Platform, ACCELERATE, was proposed in 2013 by the Cancer Drug Development Forum, Innovative Therapies for Children with Cancer, the European Network for Cancer Research in Children and Adolescents and the European Society for Paediatric Oncology. The Platform, comprising multiple stakeholders in paediatric oncology, has three working groups, one with responsibility for promoting and developing high-quality MoA-informed paediatric drug development programmes, including specific measures for adolescents. Key is the establishment of a freely accessible aggregated database of paediatric biological tumour drug targets to be aligned with an aggregated pipeline of drugs. This will enable prioritisation and conduct of early phase clinical paediatric trials to evaluate these drugs against promising therapeutic targets and to generate clinical paediatric efficacy and safety data in an accelerated time frame. Through this work, the Platform seeks to ensure that potentially effective drugs, where the MoA is known and thought to be relevant to paediatric

    Aquaculture is the fastest growing food producing sector in the world and it is expected to produce significant quantities of fish in the coming years to meet the growing global demand for aquatic animal products. The expansion and diversification of the sector, along with globalisation and trade liberalisation have resulted in aquatic animals and animal products moving around the world rapidly, causing serious disease outbreaks stemming from incursions of pathogens through unregulated transboundary movements. It has become necessary to develop appropriate guidelines for establishing national regulatory frameworks to improve responsibility in transboundary movement of live aquatic animals. In 2000, the Food and Agriculture Organization of the United Nations (FAO), in collaboration with the Network of Aquaculture Centres in Asia-Pacific (NACA) and in partnership with 21 Asian countries, developed the Asia Regional Technical Guidelines on Health Management for the Responsible Movement of Live Aquatic Animals. The present article outlines the development process of the guidelines, the lessons learned from their implementation at national level and the way forward. PMID:18666478

    The volume of global stranded natural gas reserves is impressive totalling more than a third of the world's proven natural gas reserves. In Brazil, recent discoveries operated by PETROBRAS with the share of other companies indicate the tendency of incorporating stranded gas reserves (associated or not) to the country's total reserves. The objective of this study is to perform a technical and economic analysis of the implementation of small-scale GTL technology for the exploitation of stranded associated natural gas offshore in Brazil. Thus, the study initially held a survey of the processes of gasification and the manufacturers of technologies and projects based on these processes, specifically for offshore applications. Then, the offshore environment conditions were examined. After the confrontation of the available technologies and the operational conditions, one technology was chosen to be assessed by the economic analysis. The results show that GTL offshore option becomes feasible for the minimum oil price of approximately $50.00 per barrel. This price is greater than the value of robustness adopted by PETROBRAS, however there is still the possibility of cost reductions for the feasibility of new technologies. (author)

    Purpose: To assess the impact of experience and technical changes on peri- and postimplantation (1 month later) dosimetry for permanent prostate brachytherapy (PPB). Patients and methods: From July 2003 to May 2010, 150 prostate cancer patients underwent low-dose, loose-seed I{sup 125} PPB as monotherapy with intraoperative planning. Patients were divided into three groups - P1 (n = 64), P2 (n = 45), P3 (n = 41) - according to the technical changes that occurred during the study period: use of an automatic stepper at the beginning of P2 and a high-frequency ultrasound probe in P3. Peri- and postimplantation dosimetric parameters (on day 30) were reported: D90 (dose received by 90% of prostate volume), V100 and V150 (prostate volume receiving, respectively, 100% and 150% of the prescribed dose), D2 cc and D0.1 cc (doses received by 2 cc and 0.1 cc of the rectum), R100 (rectum volume that received 100% of the prescribed dose), and D10 and D30 (doses received by 10% and 30% of the urethra, only during peri-implantation). Results: We observed a decrease in the number of needles and seeds used over time. The mean peri-implantation D90 was 187.52 Gy without a significant difference between the three periods (p = 0.48). The postimplantation D90, V100, and V150 parameters were, respectively, 168.3 Gy, 91.9%, and 55% with no significant difference between the three periods. The peri-implantation and postimplantation D0.1 cc and R100 significantly decreased over time; on day 30: D0.1 cc P1 = 223.1 Gy vs. D0.1 cc P3 = 190.4 Gy (p = 8.10- 5) and R100 P1 = 1.06 cc vs. R100 P3 = 0.53 cc (p = 0.0008). Conclusion: We observed a learning curve for the implantation parameters, which led to a significant decrease in the rectal doses without having any impact on the prostate dosimetric parameters.

  2. Dosimetric and technical aspects of intraoperative I-125 brachytherapy for stage I non-small cell lung cancer

    International Nuclear Information System (INIS)

    Initial treatment outcome data from our institution for stage I non-small cell lung cancer (NSCLC) patients have shown that sublobar resection in combination with iodine-125 (I-125) brachytherapy is associated with recurrence rates of 2.0%, compared to 18.6% with sublobar resection alone. In this work, the technical and dosimetric aspects required to execute this procedure from the radiation oncology perspective as well as an analysis of the dose distributions of patients treated with this technique are presented. In this treatment technique, I-125 seeds in vicryl suture are embedded into vicryl mesh and surgically inserted providing a 2.0 cm margin on each side of the resection staple line. A nomogram is developed to determine the suture spacing in the vicryl mesh, as a function of seed activity in order to deliver 120 Gy at a distance of 0.5 cm above and below the seed array. Post-operative dosimetry consists of a CT-based planning and dose volume analysis. Dose distributions, dose volume histograms and mean dose data for lung are analysed in a group of patients. Dosimetric results show significant lung sparing with only a small volume of lung irradiated for all patients with mean lung dose values ranging from 1.5 Gy to 5.4 Gy. Lung brachytherapy with I-125 at the time of sublobar resection is a highly conformal option of dose delivery for stage I NSCLC patients with compromised physiologic reserve. Patient-related toxicity clinically measured by loss of pulmonary function and radiation-induced pneumonitis have not been linked to this procedure

    Introduction The sentinel node technique (S.N.) was proposed in cervical cancers in order to optimise the diagnosis of metastases and the lymphatic micrometastases in the early stages while avoiding useless wide clearings out. The identification of this node is done by injection of a dye and/or a radioactive colloid and its ablation for pathological examination. Patients and methods We report the case of three patients followed for a uterine cancer having benefited from a lymphoscintigraphy before surgery. During the surgical procedure, the detection of the sentinel node was carried out after cervical injection of blue dye and using a gamma detection probe. Results The lymphoscintigraphy was positive for two cases with a positive detection for the three cases during the operation. The pathological study revealed a node metastasis for one case. The technical of the sentinel node applied to uterine cancers appears realizable essentially for uterine cancers of early stage (I). However the risk of false negative can be observed in advanced cancer (III), as it is the case of our patient having a negative lymphoscintigraphy. Conclusion The nuclear medicine is important in the detection of the sentinel node of various cancers, uterine cancer included, thus allowing an appropriate cardiologic management. (authors)

    For head and neck cancer patients treated with radiation therapy, proper immobilization of intra-oral structures is crucial in reproducing treatment positions and optimizing dose distribution. We produced a man-made tongue immobilization device for each patient subjected to this study. Reproducibility of treatment positions and dose distributions at air-and-tissue interface were compared using man-made tongue immobilization devices and conventional tongue-bites. Dental alginate and putty were used in producing man-made tongue immobilization devices. In order to evaluate reproducibility of treatment positions, all patients were CT-simulated, and linac-gram was repeated 5 times with each patient in the treatment position. An acrylic phantom was devised in order to evaluate safety of man-made tongue immobilization devices. Air, water, alginate and putty were placed in the phantom and dose distributions at air-and-tissue interface were calculated using Pinnacle (version 7.6c, Phillips, USA) and measured with EBT film. Two different field sizes (33 cm and 55 cm) were used for comparison. Evaluation of linac grams showed reproducibility of a treatment position was 4 times more accurate with man-made tongue immobilization devices compared with conventional tongue bites. Patients felt more comfortable using customized tongue immobilization devices during radiation treatment. Air-and-tissue interface dose distributions calculated using Pinnacle were 7.78% and 0.56% for 33 cm field and 55 cm field respectively. Dose distributions measured with EBT (international specialty products, USA) film were 36.5% and 11.8% for 33 cm field and 55 cm field respectively. Values from EBT film were higher. Using man-made tongue immobilization devices made of dental alginate and putty in treatment of head and neck cancer patients showed higher reproducibility of treatment position compared with using conventional mouth pieces. Man-made immobilization devices can help optimizing air

  6. Implementation of single-breath-hold cone beam CT guided hypofraction radiotherapy for lung cancer

    International Nuclear Information System (INIS)

    To analyze the feasibility of active breath control (ABC), the lung tumor reproducibility and the rationale for single-breath-hold cone beam CT (CBCT)-guided hypofraction radiotherapy. Single-breath-hold CBCT images were acquired using ABC in a cohort of 83 lung cancer patients (95 tumors) treated with hypofraction radiotherapy. For all alignments between the reference CT and CBCT images (including the pre-correction, post-correction and post-treatment CBCT images), the tumor reproducibility was evaluated via online manual alignment of the tumors, and the vertebral bone uncertainties were evaluated via offline manual alignment of the vertebral bones. The difference between the tumor reproducibility and the vertebral bone uncertainty represents the change in the tumor position relative to the vertebral bone. The relative tumor positions along the coronal, sagittal and transverse axes were measured based on the reference CT image. The correlations between the vertebral bone uncertainty, the relative tumor position, the total treatment time and the tumor reproducibility were evaluated using the Pearson correlations. Pre-correction, the systematic/random errors of tumor reproducibility were 4.5/2.6 (medial-lateral, ML), 5.1/4.8 (cranial-caudal, CC) and 4.0/3.6 mm (anterior-posterior, AP). These errors were significantly decreased to within 3 mm, both post-correction and post-treatment. The corresponding PTV margins were 4.7 (ML), 7.4 (CC) and 5.4 (AP) mm. The changes in the tumor position relative to the vertebral bone displayed systematic/random errors of 2.2/2.0 (ML), 4.1/4.4 (CC) and 3.1/3.3 (AP) mm. The uncertainty of the vertebral bone significantly correlated to the reproducibility of the tumor position (P < 0.05), except in the CC direction post-treatment. However, no significant correlation was detected between the relative tumor position, the total treatment time and the tumor reproducibility (P > 0.05). Using ABC for single-breath-hold CBCT guidance is an

    To date, conducting retrospective clinical analyses is rather difficult and time consuming. Especially in radiation oncology, handling voluminous datasets from various information systems and different documentation styles efficiently is crucial for patient care and research. With the example of patients with pancreatic cancer treated with radio-chemotherapy, we performed a therapy evaluation by using analysis tools connected with a documentation system. A total number of 783 patients have been documented into a professional, web-based documentation system. Information about radiation therapy, diagnostic images and dose distributions have been imported. For patients with disease progression after neoadjuvant chemoradiation, we designed and established an analysis workflow. After automatic registration of the radiation plans with the follow-up images, the recurrence volumes are segmented manually. Based on these volumes the DVH (dose-volume histogram) statistic is calculated, followed by the determination of the dose applied to the region of recurrence. All results are stored in the database and included in statistical calculations. The main goal of using an automatic evaluation system is to reduce time and effort conducting clinical analyses, especially with large patient groups. We showed a first approach and use of some existing tools, however manual interaction is still necessary. Further steps need to be taken to enhance automation. Already, it has become apparent that the benefits of digital data management and analysis lie in the central storage of data and reusability of the results. Therefore, we intend to adapt the evaluation system to other types of tumors in radiation oncology.

    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.

  11. Anticipating implementation of colorectal cancer screening in The Netherlands: a nation wide survey on endoscopic supply and demand

    Science.gov (United States)

    2012-01-01

    Background Colorectal cancer (CRC) screening requires sufficient endoscopic resources. The present study aims to determine the Dutch endoscopic production and manpower for 2009, evaluate trends since 2004, determine additional workload which would be caused by implementation of a CRC screening program, and inventory colonoscopy rates performed in other European countries. Methods All Dutch endoscopy units (N = 101) were surveyed for manpower and the numbers of endoscopy procedures performed in 2009. Based on calculations in the report issued by the Dutch Health Council, future additional workload caused by faecal immunochemical test (FIT) screening was estimated. The number of colonoscopies performed in Europe was evaluated by a literature search and an email-inquiry. Results Compared to 2004, there was a 24% increase in total endoscopies (N = 505,226 in 2009), and a 64% increase in colonoscopies (N = 191,339 in 2009) in The Netherlands. The number of endoscopists had increased by 4.6% (N = 583 in 2009). Five years after stepwise implementation of FIT-based CRC screening, endoscopic capacity needs to be increased an additional 15%. A lack of published data on the number of endoscopies performed in Europe was found. Based on our email-inquiry, the number of colonoscopies per 100,000 inhabitants ranged from 126 to 3,031 in 15 European countries. Conclusions Over the last years, endoscopic procedures increased markedly in The Netherlands without a corresponding increase in manpower. A FIT-based CRC screening program requires an estimated additional 15% increase in endoscopic procedures. It is very likely that current colonoscopy density varies widely across European countries.

    Abstract Background One-half of patients with cancer have pain. In nearly one out of two cancer patients with pain, this was undertreated. Inadequate pain control still remains an important problem in this group of patients. Therefore, in 2008 a national, evidence-based multidisciplinary clinical practice guideline 'pain in patients with cancer' has been developed. Yet, publishing a guideline is not enough. Implementation is needed to improve pain management. An innovative implementation stra...

    Peer Connect matches cancer survivors and caregivers (guides) with those currently experiencing cancer-related issues seeking support (partners). Motivational interviewing (MI)-based communication skills are taught to provide patient-centered support. There is little guidance about MI-based applications with cancer survivors who may have multiple coping needs. This paper addresses the results and lessons learned from implementing Peer Connect. Thirteen cancer survivors and two caregivers received a 2-day MI, DVD-based training along with six supplemental sessions. Nineteen partners were matched with guides and received telephone support. Evaluation included guide skill assessment (Motivational Interviewing Treatment Integrity Code) and 6-month follow-up surveys with guides and partners. Guides demonstrated MI proficiency and perceived their training as effective. Guides provided on average of five calls to each partner. Conversation topics included cancer fears, family support needs, coping and care issues, and cancer-related decisions. Partners reported that guides provided a listening ear, were supportive, and nonjudgmental. Limited time availability of some guides was a challenge. MI can provide support for cancer survivors and caregivers without specific behavioral concerns (e.g., weight and smoking). An MI support model was both feasible and effective and can provide additional support outside of the medical system. PMID:24078346

    The Systems Prioritization Method (SPM) is a decision-aiding tool developed by Sandia National Laboratories (SNL). SPM provides an analytical basis for supporting programmatic decisions for the Waste Isolation Pilot Plant (WIPP) to meet selected portions of the applicable US EPA long-term performance regulations. The first iteration of SPM (SPM-1), the prototype for SPM< was completed in 1994. It served as a benchmark and a test bed for developing the tools needed for the second iteration of SPM (SPM-2). SPM-2, completed in 1995, is intended for programmatic decision making. This is Volume II of the three-volume final report of the second iteration of the SPM. It describes the technical input and model implementation for SPM-2, and presents the SPM-2 technical baseline and the activities, activity outcomes, outcome probabilities, and the input parameters for SPM-2 analysis.

  17. Systems Sustainability: Implementation of Enhanced Maintenance Programs at the Kurchatov Institute, the All-Russian Research Institute of Experimental physics (VNIIEF) and the All-Russian Scientific Institute for Technical Physics (VNIITF)

    International Nuclear Information System (INIS)

    Implementation of quality maintenance programs is essential to enhancing sustainable continuous operations of United States funded Materials Protection, Control and Accountability (MPC and A) equipment/systems upgrades at various Russian nuclear facilities. An effective maintenance program is expected to provide assurances to both parties for achieving maximum continuous systems operations with minimum down time. To be effective, the program developed must focus on minimum down time for any part of a system. Minimum down time is realized through the implementation of a quality maintenance program that includes preventative maintenance, necessary diagnostic tools, properly trained technical staff, and an in-house inventory of required spare parts for repairing the impacted component of the system. A centralized maintenance management program is logistically essential for the success of this effort because of the large volume of MPC and A equipment/systems installed at those sites. This paper will discuss current programs and conditions at the Russian Research Center-Kurchatov Institute, the All-Russian Scientific Institute for Technical Physics and the All-Russian Research Institute of Experimental Physics and will address those steps necessary to implement an upgraded program at those sites

    2011-03-01

    The National Cancer Institute (NCI) is developing a patient-reported version of its Common Terminology Criteria for Adverse Events, called the "PRO-CTCAE." The PRO-CTCAE consists of a library of patient-reported items which can be administered in clinical trials to directly capture the patient experience of adverse events during cancer treatment, as well as a software platform for administering these items via computer or telephone. In order to better understand the impressions of stakeholders involved in cancer clinical research about the potential value of the PRO-CTCAE approach to capturing adverse event information in clinical research, as well as their perspectives about barriers and strategies for implementing the PRO-CTCAE in NCI-sponsored cancer trials, a survey was conducted. A survey including structured and open-ended questions was developed to elicit perceptions about the use of patient-reported outcomes (PROs) for adverse event reporting, and to explore logistical considerations for implementing the PRO-CTCAE in cancer trials. The survey was distributed electronically and by paper to a convenience sample of leadership and committee members in the NCI's cooperative group network, including principal investigators, clinical investigators, research nurses, data managers, patient advocates, and representatives of the NCI and Food and Drug Administration. Between October, 2008 through February, 2009, 727 surveys were collected. Most respondents (93%) agreed that patient reporting of adverse symptoms would be useful for improving understanding of the patient experience with treatment in cancer trials, and 88%, 80%, and 76%, respectively, endorsed that administration of PRO-CTCAE items in clinical trials would improve the completeness, accuracy, and efficiency of symptom data collection. More than three fourths believed that patient reports would be useful for informing treatment dose modifications and towards FDA regulatory evaluation of drugs. Eighty

    Purpose: Four-dimensional cone-beam CT (4D-CBCT) is a novel imaging technique to setup patients with pulmonary lesions in radiation therapy. This paper is to perform a feasibility study on the implementation of 4D-CBCT as image guidance for (1) SBRT and (2) Low Modulation (Low-Mod) IMRT in lung cancer treatment. Methods: Image artifacts and observers variability are evaluated by analyzing the 4D-CT QA phantom and patient 4D image data. There are two 4D-CBCT image artifacts: (1) Spatial artifact caused by the patient irregular breathing pattern will generate blurring and anatomy gap/overlap; (2) Cone beam scattering and hardening artifact will affect the image spatial and contrast resolution. The couch shift varies between 1mm to 3mm from different observers during the 4D-CBCT registration. Breath training is highly recommended to improve the respiratory regularity during CT simulation and treatment, especially for SBRT. Elekta XVI 4.5 Symmetry protocol is adopted in the patient 4DCBCT scanning and intensity-based registration. Physician adjustments on the auto-registration are involved prior to the treatment. Physician peer review on 4D-CBCT image acquisition and registration is also recommended to reduce the inter-observer variability. The average 4D-CT in reference volume coordinates is exported to MIM Vista 5.6.2 to manually fuse to the planning CT for further evaluation. Results: (1) SBRT: 4DCBCT is performed in dry-run and in each treatment fraction. Image registration and couch shift are reviewed by another physician on the 1st fraction before the treatment starts. (2) Low-Mod IMRT: 4D-CBCT is performed and peer reviewed on weekly basis. Conclusion: 4D-CBCT in SBRT dry-run can discover the ITV discrepancies caused by the low quality 4D-CT simulation. 4D-CBCT during SBRT and Low-Mod IMRT treatment provides physicians more confidence to target lung tumor and capability to evaluate inter-fractional ITV changes.

  6. Lung cancer epidemiology in New Mexico uranium miners: Final technical report, July 1, 1986--February 28, 1989

    International Nuclear Information System (INIS)

    A case-control study within the cohort was performed; the subjects included 65 cases and 230 age-matched controls, most with exposures below 1000 Working Level Months (WLM). The risk for lung cancer was increased for all cumulative exposures to radon decay products of 100 WLM or more. With exclusion of subjects with exposures above 1000 WLM, the estimated excess relative risk was 1.1% per WLM. The risk was greater for younger subjects and the data were consistent with a multiplicative interaction between cigarette smoking and exposure to radon progeny. The findings of the case-control study have been confirmed by conventional cohort analysis, supplemented by Poisson regression. For the entire cohort, the ratio of observed to expected lung cancer deaths was 4.1 (95% confidence limits 3.2, 5.1). A significant number of excess deaths was also found for the category ''other accidents.'' For lung cancer, the ratio of observed to expected deaths increased with cumulative exposure. Additional multivariate analyses, using the Cox proportional hazards model, are in progress. Additionally, a new panel of pathologists has been formed to review histopathological material from all available cases. 15 refs., 2 figs., 15 tabs

    International Nuclear Information System (INIS)

    This investigation assessed the health effects of radon daughter exposure in New Mexico uranium miners. Cumulative exposures sustained by earlier New mexicon miners are well below those of the Colorado Plateau; more recent miners have had even lower exposures, governed by the Federal standard of 4 working level months (WLM) annually. Cohort studies of mortality in two separate groups are in progress: a retrospective cohort study of an already selected group of 3055 miners with first underground experience before 1971; and a prospective cohort study of miners first exposed from 1971 on. For both groups, records of company physical examinations will supply mining and smoking histories. Radon daughter exposures after 1967 are available from the companies. For 1967 and earlier, they will be estimated from records of measurements made by the state. During this investigation, mortality in the cohort of earlier miners through December, 1982, will be examined. The feasibility of a large prospective cohort study of more recent miners will also be determined. Analysis of the retrospective cohort data will focus on dose-response relationships for lung cancer, interaction of cigarette smoking with radon daughter exposure in lung cancer etiology, and the occurrence of lung diseases other than cancer. Conventional cohort analysis and multivariate techniques will be used

    The European Union (EU) Broiler Directive (2007/43/EC) is unique amongst current EU Directives, which address animal welfare, in that it uses outcome data collected at abattoirs and on farm to monitor on-farm broiler welfare and vary the maximum permitted stocking density on farm. In this study, we describe how, by bringing together personnel from the competent authorities in 22 member states (MSs) who have responsibility for implementing the Directive, and engaging in exchange of information and technical methods regarding the Broiler Directive, it has been possible to identify differences in approach with regard to 'what data is being collected, and by whom' across EU MSs. Online questionnaires and workshop exercises enabled us to identify priority areas for knowledge transfer and training. For example, foot pad dermatitis, hock burn, dead on arrival and total rejections (birds rejected as unfit for human consumption by the meat inspection staff at slaughter) were identified by the MSs as measures of medium-to-low priority in terms of knowledge transfer because there are assessment methods for these conditions that are already well accepted by competent authorities. On the other hand, breast lesions, cellulitis, emaciation, joint lesions, respiratory problems, scratches, wing fractures and a number of environmental measures were identified as having high priority in terms of knowledge transfer. The study identified that there is significant variability in the stage of implementation between MSs, and responses from the participating MSs indicated that sharing of guidance and technical information between MSs may be of value in the future set-up process for those MSs engaged in implementation of the Directive.

    Full Text Available Abstract Background Although treatment regimen have improved in the last few years, prostate cancer patients following a radical prostatectomy still experience severe disease- and treatment-related side effects, including urinary incontinence, erectile dysfunction and psychological issues. Despite high incidence rates and the common adverse effects there is a lack of supportive measures for male patients and specific physical exercise recommendations for prostate cancer patients during rehabilitation or in the aftercare are still missing. Methods/Design The ProRehab Project aims to establish rehabilitative sports groups particularly for prostate cancer patients and to evaluate the effects of the offered exercise program. Starting 8–12 weeks after prostatectomy or combination therapy, prostate cancer patients will exercise for 15 months within a patient preference randomized controlled trial. One exercise session will be conducted within a pre-established rehabilitative sports group, while the other will be completed independently. Patients in the control group will not participate in the intervention. The main outcomes of the study include aerobic fitness, quality of life, incontinence and erectile dysfunction. Discussion By combining science, practice, and public relations the first rehabilitative sports groups for prostate cancer patients in Germany have been set up and thus contribute to the care structure for prostate cancer patients. By offering a 15-month physical exercise intervention that is conducted in supervised group sessions, long-term lifestyle changes and therefore improvements in quality of life in prostate cancer patients can be expected.

  13. Reference computations of public dose and cancer risk from airborne releases of plutonium. Nuclear safety technical report

    International Nuclear Information System (INIS)

    This report presents results of computations of doses and the associated health risks of postulated accidental atmospheric releases from the Rocky Flats Plant (RFP) of one gram of weapons-grade plutonium in a form that is respirable. These computations are intended to be reference computations that can be used to evaluate a variety of accident scenarios by scaling the dose and health risk results presented here according to the amount of plutonium postulated to be released, instead of repeating the computations for each scenario. The MACCS2 code has been used as the basis of these computations. The basis and capabilities of MACCS2 are summarized, the parameters used in the evaluations are discussed, and results are presented for the doses and health risks to the public, both the Maximum Offsite Individual (a maximally exposed individual at or beyond the plant boundaries) and the population within 50 miles of RFP. A number of different weather scenarios are evaluated, including constant weather conditions and observed weather for 1990, 1991, and 1992. The isotopic mix of weapons-grade plutonium will change as it ages, the 241Pu decaying into 241Am. The 241Am reaches a peak concentration after about 72 years. The doses to the bone surface, liver, and whole body will increase slightly but the dose to the lungs will decrease slightly. The overall cancer risk will show almost no change over this period. This change in cancer risk is much smaller than the year-to-year variations in cancer risk due to weather. Finally, x/Q values are also presented for other applications, such as for hazardous chemical releases. These include the x/Q values for the MOI, for a collocated worker at 100 meters downwind of an accident site, and the x/Q value integrated over the population out to 50 miles

  14. Comparison of three radiotherapy technics in three-dimensional dosimetric planning for non-small cell lung cancer

    International Nuclear Information System (INIS)

    Objective: To assess and delineate the dosimetric shortcomings of conventional radiotherapy planning, as compared with the three-dimensional treatment planning system, and to obtain a better technique in the treatment of lung cancers. Methods: Thirteen patients with stage III A-III B non-small cell lung cancer were chosen in the present study. Using the Cadplan 6.0.8 treatment planning system, three different methods of radiotherapy planning: conventional planning, conventional and conformal planning, and conformal planning were designed for each patient. The total radiation dose was 66 Gy and DVHs were used to assess the dosimetric distribution in the gross tumor volume and the surrounding organs at risk. Results: No significant dosimetric disparity in the target volume was found among the three designs, according to anticipated therapeutic requirements. The conformity indices were 0.13, 0.24 and 0.35 for these three radiotherapy designs. The mean lung volumes which received radiation dose of ≥20 Gy were 32%, 26% and 25%. The mean maximum dose at the spinal cord were 42 Gy, 49 Gy and 33 Gy. The mean esophageal volume which received radiation of ≥50 Gy were 32%, 34% and 22%, and the mean radiation dose to the heart were 18 Gy, 15 Gy and 12 Gy, respectively. Conclusions: Conventional radiotherapy planning is able to meet the demands of dosimetric requirements for radiation treatment of lung cancers. The three dimensional conformal radiation therapy planning system is able to provide superior delivery of high dose to the target volume without inflicting too high a risk to the surrounding normal tissues and organs

    The purpose of this study was to determine whether image characteristics could be used to predict the outcome of ROC studies in PET/CT imaging. Patients suspected for recurrent thyroid cancer underwent a standard whole body (WB) examination and an additional high-resolution head-and-neck (HN) F18-FDG PET/CT scan. The value of the latter was determined with an ROC study, the results of which showed that the WB+HN combination was better than WB alone for thyroid cancer detection and diagnosis. Following the ROC experiment, the WB and HN images of confirmed benign or malignant thyroid disease were analyzed and first and second order textural features were determined. Features included minimum, mean, and maximum intensity, as well as contrast in regions of interest encircling the thyroid lesions. Lesion size and standard uptake values (SUV) were also determined. Bivariate analysis was applied to determine relationships between WB and HN features and between observer ROC responses and the various feature values. The two sets showed significant associations in the values of SUV, contrast, and lesion size. They were completely different when the intensities were considered; no relationship was found between the WB minimum, maximum, and mean ROI values and their HN counterparts. SUV and contrast were the strongest predictors of ROC performance on PET/CT examinations of thyroid cancer. The high resolution HN images seem to enhance these relationships but without a single dramatic effect as was projected from the ROC results. A combination of features from both WB and HN datasets may possibly be a more robust predictor of ROC performance.

  16. Reference computations of public dose and cancer risk from airborne releases of plutonium. Nuclear safety technical report

    Energy Technology Data Exchange (ETDEWEB)

    Peterson, V.L.

    1993-12-23

    This report presents results of computations of doses and the associated health risks of postulated accidental atmospheric releases from the Rocky Flats Plant (RFP) of one gram of weapons-grade plutonium in a form that is respirable. These computations are intended to be reference computations that can be used to evaluate a variety of accident scenarios by scaling the dose and health risk results presented here according to the amount of plutonium postulated to be released, instead of repeating the computations for each scenario. The MACCS2 code has been used as the basis of these computations. The basis and capabilities of MACCS2 are summarized, the parameters used in the evaluations are discussed, and results are presented for the doses and health risks to the public, both the Maximum Offsite Individual (a maximally exposed individual at or beyond the plant boundaries) and the population within 50 miles of RFP. A number of different weather scenarios are evaluated, including constant weather conditions and observed weather for 1990, 1991, and 1992. The isotopic mix of weapons-grade plutonium will change as it ages, the {sup 241}Pu decaying into {sup 241}Am. The {sup 241}Am reaches a peak concentration after about 72 years. The doses to the bone surface, liver, and whole body will increase slightly but the dose to the lungs will decrease slightly. The overall cancer risk will show almost no change over this period. This change in cancer risk is much smaller than the year-to-year variations in cancer risk due to weather. Finally, x/Q values are also presented for other applications, such as for hazardous chemical releases. These include the x/Q values for the MOI, for a collocated worker at 100 meters downwind of an accident site, and the x/Q value integrated over the population out to 50 miles.

  18. Technical co-operation with International Atomic Energy Agency to implement in Romania programs and methodologies for development of the energy sector taking into account the nuclear energy

    International Nuclear Information System (INIS)

    In order to foster national TC projects, the AIEA acts in response to Member States needs for assistance. Following the request raised by Romania, the IAEA implemented the project 'Energy and Nuclear Power Planning Study' during the period January 1991 - February 1996 in the framework of the TC program with the intent of enhancing the national capabilities for conducting long-term energy demand analysis and supply planning, taking into account the nuclear energy, too, by using the Energy and Power Evaluation Programs (ENPEP) based on the integrated energy system analyses methodology. IAEA provided training in the use of ENPEP modules through the Romanian experts participation in the Inter-regional Training Course (ITC). In 1992, nine international organizations joint together to launch the inter-agency project on 'Databases and Methodologies for Comparative Assessment of Different Energy Sources for electricity generation', in short DECADES. The project's aim is to facilitate the development of sustainable energy strategies as an integral part of planning and decision making in the electricity sector. Romania participated in the first phase of the DECADES project with the country case study 'Comparative assessment of nuclear power plant and combined cycle gas fired power plants'. The second phase of the DECADES project (1996-2000) focuses on disseminating the current computer tools providing user training in their application, supporting country studies and developing new analytical capabilities. Romania takes part in this project to implement the full energy chain comparative assessment methodology and tools of the technologies for electricity generation. The implementation of IAEA methodologies and tools in Romania energy sector expansion planning has determined: implementation of the integrated energy system methodology; Romanian methodologies aligning to the existent international standards; improvement of Romania experts capability to perform complex analyses

    Background Low-dose computed tomography (ldct) screening has been shown to reduce mortality from lung cancer; however, the optimal screening duration and “at risk” population are not known. Methods The Cancer Risk Management Model developed by Statistics Canada for the Canadian Partnership Against Cancer includes a lung screening module based on data from the U.S. National Lung Screening Trial (nlst). The base-case scenario reproduces nlst outcomes with high fidelity. The impact in Canada of annual screening on the number of incident cases and life-years gained, with a wider range of age and smoking history eligibility criteria and varied participation rates, was modelled to show the magnitude of clinical benefit nationally and by province. Life-years gained, costs (discounted and undiscounted), and resource requirements were also estimated. Results In 2014, 1.4 million Canadians were eligible for screening according to nlst criteria. Over 10 years, screening would detect 12,500 more lung cancers than the expected 268,300 and would gain 9200 life-years. The computed tomography imaging requirement of 24,000–30,000 at program initiation would rise to between 87,000 and 113,000 by the 5th year of an annual nlst-like screening program. Costs would increase from approximately $75 million to $128 million at 10 years, and the cumulative cost nationally over 10 years would approach $1 billion, partially offset by a reduction in the costs of managing advanced lung cancer. Conclusions Modelling various ways in which ldct might be implemented provides decision-makers with estimates of the effect on clinical benefit and on resource needs that clinical trial results are unable to provide.

    Alcohol drinking at high doses is a risk factor for head and neck cancer, and exposure to acetaldehyde, the principle metabolite of alcohol, is supposed to account for the increased risk. Individuals homozygous for the 2 variant allele of aldehyde dehydrogenase 2 (ALDH2) are unable to metabolize acetaldehyde, which prevents them from alcohol drinking, whereas 1 2 have 6-fold higher blood acetaldehyde concentration postalcohol consumption with respect to 1 1. According to the concept of Mendelian randomization, because this polymorphism is distributed randomly during gamete formation, its association with head and neck cancer should be not confounded by smoking. We carried out a meta-analysis of ALDH2 and head and neck cancer searching for relevant studies on Medline and Embase up to January 31, 2008, and investigated the consistency between the expected odds ratio (OR) among drinkers from the largest pooled analysis among never smokers and the observed OR from this meta-analysis by an interaction test. Six studies were selected (945 cases, 2,917 controls). The OR of head and neck cancer among 2 2 was 0.53 [95% confidence interval (95% CI), 0.28-1.00] relative to 1 1 and 1.83 (95% CI, 1.21-2.77) among 1 2. The expected OR for head and neck cancer due to alcohol intake among 1 1 was 1.38 (95% CI, 0.88-2.17) and the observed OR among 1 1 compared with 2*2 from this meta-analysis was 1.88 (95% CI, 1.00-3.57; P for interaction = 0.43). Besides showing the effectiveness of the Mendelian randomization approach, these findings support the theory that alcohol increases head and neck cancer risk through the carcinogenic action of acetaldehyde.

  6. Implementing waste minimization at an active plutonium processing facility: Successes and progress at technical area (TA) -55 of the Los Alamos National Laboratory

    International Nuclear Information System (INIS)

    The Los Alamos National Laboratory has ongoing national security missions that necessitate increased plutonium processing. The bulk of this activity occurs at Technical Area -55 (TA-55), the nations only operable plutonium facility. TA-55 has developed and demonstrated a number of technologies that significantly minimize waste generation in plutonium processing (supercritical CO2, Mg(OH)2 precipitation, supercritical H2O oxidation, WAND), disposition of excess fissile materials (hydride-dehydride, electrolytic decontamination), disposition of historical waste inventories (salt distillation), and Decontamination ampersand Decommissioning (D ampersand D) of closed nuclear facilities (electrolytic decontamination). Furthermore, TA-55 is in the process of developing additional waste minimization technologies (molten salt oxidation, nitric acid recycle, americium extraction) that will significantly reduce ongoing waste generation rates and allow volume reduction of existing waste streams. Cost savings from reduction in waste volumes to be managed and disposed far exceed development and deployment costs in every case. Waste minimization is also important because it reduces occupational exposure to ionizing radiation, risks of transportation accidents, and transfer of burdens from current nuclear operations to future generations

    Ovarian cancer (OvCa) is the most lethal gynecologic disease in the United States, with an overall 5-year survival rate of 44.5%, about half of the 89.2% for all breast cancer patients. To identify factors that possibly contribute to the long-term survivorship of women with OvCa, we conducted a comprehensive online Ovarian Cancer Survivorship Survey from 2009 to 2013. This paper presents the design and implementation of our survey, introduces its resulting data source, the OVA-CRADLE™ (Clinical Research Analytics and Data Lifecycle Environment), and illustrates a sample application of the survey and data by an analysis of prediagnosis symptoms, using text mining and statistics. The OVA-CRADLE™ is an application of our patented Physio-MIMI technology, facilitating Web-based access, online query and exploration of data. The prediagnostic symptoms and association of early-stage OvCa diagnosis with endometriosis provide potentially important indicators for future studies in this field. PMID:25861211

    (18)F-FDG PET/CT plays a crucial role in the diagnosis and management of patients with head and neck squamous cell cancer (HNSCC). The major clinical applications of this method include diagnosing an unknown primary tumour, identifying regional lymph node involvement and distant metastases, and providing prognostic information. (18)F-FDG PET/CT is also used for precise delineation of the tumour volume for radiation therapy planning and dose painting, and for treatment response monitoring, by detecting residual or recurrent disease. Most of these applications would benefit from a quantitative approach to the disease, but the quantitative capability of (18)F-FDG PET/CT is still underused in HNSCC. Innovations in PET/CT technology promise to overcome the issues that until now have hindered the employment of dynamic procedures in clinical practice and have limited "quantification" to the evaluation of standardized uptake values (SUV), de facto a semiquantitative parameter, the limits of which are well known to the nuclear medicine community. In this paper the principles of quantitative imaging and the related technical issues are reviewed so that professionals involved in HNSCC management can reflect on the advantages of "true" quantification. A discussion is then presented on how semiquantitative information is currently used in clinical (18)F-FDG PET/CT applications in HNSCC, by discussing the improvements that could be obtained with more advanced and "personalized" quantification techniques.

    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

  13. How do radiation oncology health professionals inform breast cancer patients about the medical and technical aspects of their treatment?

    International Nuclear Information System (INIS)

    Background and purpose: Radiation therapy patients need information to make treatment decisions, understand treatment and manage side effects. The purpose of this study was to (1) Identify information about radiation therapy routinely provided to breast cancer patients; (2) Determine which health professionals provide information; (3) Examine whether information is routinely provided at the same time points; and (4) Determine whether health professionals and patients place similar importance on specific information. Materials and methods: Health professionals in radiation therapy departments in Australia and New Zealand completed self-administered questionnaires. Results were analysed and compared to patient responses from a previous study. Results: Forty-one of 52 departments participated in this survey. Information provision was inconsistent between departments in terms of how and when information was given. Although the types of information provided to patients appeared to align with patients' needs, health professionals and patients placed different levels of importance on specific information. Conclusions: A wide range of information are provided to patients. However, the priority given to different information needs and the focus of information provision may not be optimal from the perspectives of patients. Further research needs to be conducted to determine patients' information needs and to develop specific information resources tailored to meet these needs

  19. Evaluation of physical parameters and implementation of quality control in mammography diagnosed for a pilot of breast cancer screening in the Caja Costarricense de Seguro Social (CCSS)

    International Nuclear Information System (INIS)

    The purpose of mammography has been to provide the contrast between the lesion and adjacent healthy tissue of the breast. The quality control which should be performed in mammography services is essential to obtain the necessary contrast in mammography and thus achieve a prompt detection of breast lesions. The quality control program has helped to obtain exact diagnosis in mammography and has contributed to reduce mortality from breast cancer in Costa Rica. The Caja Costarricense de Seguro Social (CCSS) has sought to improve the quality of mammograms performed in the different health centers by implementing quality control programs in the services. The evaluation of the physical parameters has had as aim to perform an assessment of the equipment used in mammography facilities. The image quality, dosimetry, optical density, performance, accuracy and repeatability of voltage applied to the tube, filtration and Half-value layer in system of screen film mammography have been evaluated. The usefulness of quality control programs and needs of the services to implement a pilot plan for breast screening, can be seen when comparing the obtained results. The protocol of Mammography Quality Control, TECDOC 1517 from the International Atomic Energy Agency (IAEA), is implemented with this project and the associated software in four of the six hospitals evaluated in this study.

  2. Technical Note: Implementation of biological washout processes within GATE/GEANT4—A Monte Carlo study in the case of carbon therapy treatments

    International Nuclear Information System (INIS)

    Purpose: The imaging of positron emitting isotopes produced during patient irradiation is the only in vivo method used for hadrontherapy dose monitoring in clinics nowadays. However, the accuracy of this method is limited by the loss of signal due to the metabolic decay processes (biological washout). In this work, a generic modeling of washout was incorporated into the GATE simulation platform. Additionally, the influence of the washout on the β+ activity distributions in terms of absolute quantification and spatial distribution was studied. Methods: First, the irradiation of a human head phantom with a 12C beam, so that a homogeneous dose distribution was achieved in the tumor, was simulated. The generated 11C and 15O distribution maps were used as β+ sources in a second simulation, where the PET scanner was modeled following a detailed Monte Carlo approach. The activity distributions obtained in the presence and absence of washout processes for several clinical situations were compared. Results: Results show that activity values are highly reduced (by a factor of 2) in the presence of washout. These processes have a significant influence on the shape of the PET distributions. Differences in the distal activity falloff position of 4 mm are observed for a tumor dose deposition of 1 Gy (Tini = 0 min). However, in the case of high doses (3 Gy), the washout processes do not have a large effect on the position of the distal activity falloff (differences lower than 1 mm). The important role of the tumor washout parameters on the activity quantification was also evaluated. Conclusions: With this implementation, GATE/GEANT 4 is the only open-source code able to simulate the full chain from the hadrontherapy irradiation to the PET dose monitoring including biological effects. Results show the strong impact of the washout processes, indicating that the development of better models and measurement of biological washout data are essential

    {sup 18}F-FDG PET/CT plays a crucial role in the diagnosis and management of patients with head and neck squamous cell cancer (HNSCC). The major clinical applications of this method include diagnosing an unknown primary tumour, identifying regional lymph node involvement and distant metastases, and providing prognostic information. {sup 18}F-FDG PET/CT is also used for precise delineation of the tumour volume for radiation therapy planning and dose painting, and for treatment response monitoring, by detecting residual or recurrent disease. Most of these applications would benefit from a quantitative approach to the disease, but the quantitative capability of {sup 18}F-FDG PET/CT is still underused in HNSCC. Innovations in PET/CT technology promise to overcome the issues that until now have hindered the employment of dynamic procedures in clinical practice and have limited ''quantification'' to the evaluation of standardized uptake values (SUV), de facto a semiquantitative parameter, the limits of which are well known to the nuclear medicine community. In this paper the principles of quantitative imaging and the related technical issues are reviewed so that professionals involved in HNSCC management can reflect on the advantages of ''true'' quantification. A discussion is then presented on how semiquantitative information is currently used in clinical {sup 18}F-FDG PET/CT applications in HNSCC, by discussing the improvements that could be obtained with more advanced and ''personalized'' quantification techniques.

  5. Design and implementation of a decision support system for breast cancer treatment based on clinical practice guidelines

    International Nuclear Information System (INIS)

    Evidence based medicine is the clinical practice that uses medical data and proof in order to make efficient clinical decisions. Information technology (IT) can play a crucial role in exploiting the huge size of raw medical data involved. In an attempt to improve clinical efficacy, health care society nowadays also utilizes a new assistant, clinical guidelines. Our research concerns the medical domain of the breast cancer disease. Our research's focus is twofold; our primary goal is to ensure consistency in clinical practice by importing clinical guidelines in an IT driven decision support system (DSS). Furthermore, we seek to improve visualization of disease specific, clinical data, providing for it's faster and more efficient use. (orig.)

    A population-based organised cervical cancer screening programme (OCCSP) was introduced in Poland in 2006. In this study we have aimed to analyse whether selected parameters related to invasive cervical cancer (ICC) of patients diagnosed in two distant gynaecological oncology centres changed after the first screening round of the programme run between 2006–2008. We have run a retrospective cross-sectional analysis of 189 women diagnosed with ICC between 2002–2005 (directly before introduction of the programme) and 165 patients diagnosed between 2009–2012 (just after the first screening round of the programme) and compared their age at diagnosis, histology, stage of tumours and overall survival (OS). Mean age of patients diagnosed in years 2002–2005 and 2009–2012 was 52.1 and 52.6 years respectively. Squamous cell carcinomas constituted 90.5% and 86.1% of tumours diagnosed in years 2002–2005 and 2009–2012 respectively and the rest of tumours had glandular and other histologies. 74.5% and 61.0% of women diagnosed in years 2002–2005 and 2009–2012 respectively had early ICC (FIGO—International Federation of Gynaecology and Obstetrics stages I-IIA) and the rest had advanced disease (FIGO IIB-IV). We have noticed no significant differences in mean age of patients, histology of tumours and OS of patients with ICC diagnosed before and after the first screening round of OCSSP in Poland. Advanced stages of ICC were more commonly diagnosed after the introduction of OCSSP. Changes only in some clinical parameters of patients with ICC were noticed before and after the first screening round of OCSSP in Poland but OS of patients remained the same. PMID:27196050

    Molecular diagnosis of hereditary breast and ovarian cancer (HBOC) by standard methodologies has been limited to the BRCA1 and BRCA2 genes. With the recent development of new sequencing methodologies, the speed and efficiency of DNA testing have dramatically improved. The aim of this work was to validate the use of next-generation sequencing (NGS) for the detection of BRCA1/BRCA2 point mutations in a diagnostic setting and to study the role of other genes associated with HBOC in Portuguese families. A cohort of 94 high-risk families was included in the study, and they were initially screened for the two common founder mutations with variant-specific methods. Fourteen index patients were shown to carry the Portuguese founder mutation BRCA2 c.156_157insAlu, and the remaining 80 were analyzed in parallel by Sanger sequencing for the BRCA1/BRCA2 genes and by NGS for a panel of 17 genes that have been described as involved in predisposition to breast and/or ovarian cancer. A total of 506 variants in the BRCA1/BRCA2 genes were detected by both methodologies, with a 100 % concordance between them. This strategy allowed the detection of a total of 39 deleterious mutations in the 94 index patients, namely 10 in BRCA1 (25.6 %), 21 in BRCA2 (53.8 %), four in PALB2 (10.3 %), two in ATM (5.1 %), one in CHEK2 (2.6 %), and one in TP53 (2.6 %), with 20.5 % of the deleterious mutations being found in genes other than BRCA1/BRCA2. These results demonstrate the efficiency of NGS for the detection of BRCA1/BRCA2 point mutations and highlight the genetic heterogeneity of HBOC. PMID:27553368

    Purpose: To evaluate the clinical implementation of an online adaptive plan-of-the-day protocol for nonrigid target motion management in locally advanced cervical cancer intensity modulated radiation therapy (IMRT). Methods and Materials: Each of the 64 patients had four markers implanted in the vaginal fornix to verify the position of the cervix during treatment. Full and empty bladder computed tomography (CT) scans were acquired prior to treatment to build a bladder volume-dependent cervix-uterus motion model for establishment of the plan library. In the first phase of clinical implementation, the library consisted of one IMRT plan based on a single model-predicted internal target volume (mpITV), covering the target for the whole pretreatment observed bladder volume range, and a 3D conformal radiation therapy (3DCRT) motion-robust backup plan based on the same mpITV. The planning target volume (PTV) combined the ITV and nodal clinical target volume (CTV), expanded with a 1-cm margin. In the second phase, for patients showing >2.5-cm bladder-induced cervix-uterus motion during planning, two IMRT plans were constructed, based on mpITVs for empty-to-half-full and half-full-to-full bladder. In both phases, a daily cone beam CT (CBCT) scan was acquired to first position the patient based on bony anatomy and nodal targets and then select the appropriate plan. Daily post-treatment CBCT was used to verify plan selection. Results: Twenty-four and 40 patients were included in the first and second phase, respectively. In the second phase, 11 patients had two IMRT plans. Overall, an IMRT plan was used in 82.4% of fractions. The main reasons for selecting the motion-robust backup plan were uterus outside the PTV (27.5%) and markers outside their margin (21.3%). In patients with two IMRT plans, the half-full-to-full bladder plan was selected on average in 45% of the first 12 fractions, which was reduced to 35% in the last treatment fractions. Conclusions: The implemented

    Full Text Available Abstract Background Cancer program delivery, like the rest of health care in Canada, faces two ongoing challenges: to coordinate a pan-Canadian approach across complex provincial jurisdictions, and to facilitate the rapid translation of knowledge into clinical practice. Communities of practice, or CoPs, which have been described by Etienne Wenger as a collaborative learning platform, represent a promising solution to these challenges because they rely on bottom-up rather than top-down social structures for integrating knowledge and practice across regions and agencies. The communities of practice model has been realized in the corporate (e.g., Royal Dutch Shell, Xerox, IBM, etc and development (e.g., World Bank sectors, but its application to health care is relatively new. The Canadian Partnership Against Cancer (CPAC is exploring the potential of Wenger's concept in the Canadian health care context. This paper provides an in-depth analysis of Wenger's concept with a focus on its applicability to the health care sector. Discussion Empirical studies and social science theory are used to examine the utility of Wenger's concept. Its value lies in emphasizing learning from peers and through practice in settings where innovation is valued. Yet the communities of practice concept lacks conceptual clarity because Wenger defines it so broadly and sidelines issues of decision making within CoPs. We consider the implications of his broad definition to establishing an informed nomenclature around this specific type of collaborative group. The CoP Project under CPAC and communities of practice in Canadian health care are discussed. Summary The use of communities of practice in Canadian health care has been shown in some instances to facilitate quality improvements, encourage buy in among participants, and generate high levels of satisfaction with clinical leadership and knowledge translation among participating physicians.

    An interactive audio and video telemedicine feasibility program was established to provide counseling on breast cancer risk-reducing strategies for underserved, high-risk Alaskan native women through a collaboration among the Alaska Native Medical Center, the Mayo Clinic Breast Clinic, Mayo's Center for Innovation, and the Alaska Federal Health Care Access Network. The telemedicine model included a navigator to facilitate patient encounters (referrals, electronic records, and scheduling) and a subscription billing contract. Between January 1 and December 31, 2011, 60 consultations were provided to the Alaska Native Medical Center. A survey of a sample of 15 women demonstrated overall patient satisfaction of 98% pertaining to the experience, technology, and medical consultation. The referring physician satisfaction, from 11 visit surveys and 8 referring physicians, revealed 99% satisfaction with the service. In this telemedicine pilot study, we demonstrated the feasibility of a telemedicine program to provide integrated specialty care that resulted in a positive effect on patient satisfaction. This program has a sustainable business model, thus creating a new modality for health care delivery. PMID:23274020

  13. Implementation and utility of a daily ultrasound-based localization system with intensity-modulated radiotherapy for prostate cancer

    International Nuclear Information System (INIS)

    Purpose: To evaluate the clinical feasibility of daily computer-assisted transabdominal ultrasonography for target position verification in the setting of intensity-modulated radiotherapy (IMRT) for prostate cancer. Methods and Materials: Twenty-three patients with clinically localized prostate cancer were treated using a sequential tomotherapy IMRT technique (Peacock) and daily computer-assisted transabdominal ultrasonography (BAT) for target localization. Patients were instructed to maintain a full bladder and were placed in the supine position using triangulation tattoos and a leg immobilizer to minimize pelvic rotation. The BAT ultrasound system is docked to the treatment collimator and electronically imports the CT simulation target contours and isocenter. The system is able to use the machine isocenter as a reference point to overlay the corresponding CT contours onto the ultrasound images captured in the transverse and sagittal planes. A touch screen menu is used to maneuver the CT contours in three dimensions such that they match the ultrasound images. The system then displays the three-dimensional couch shifts required to produce field alignment. Data were prospectively collected to measure the frequency by which useful ultrasound images were obtained, the amount of time required for localization/setup, and the direction/magnitude of the positional adjustments. Results: Of the 23 patients, the BAT ultrasound system produced images of sufficient quality to perform the overlay of the CT contours in 19 patients such that positional verification could be reliably performed. Poor image quality was associated with patient inability to maintain a full bladder, large body habitus, or other anatomic constraints. Of the 19 assessable patients, a total of 185 treatment alignments were performed (mean 8.8/patient). For all cases, the average time required for the daily ultrasound imaging and positional adjustments was 11.9 min. After the initial 5 cases, the user

  14. Application of IMAT versus fixed-gantry IMRT in cervical esophageal cancer : A comparison in dosimetry and implementation

    International Nuclear Information System (INIS)

    Objective: To compare and analyze the characteristics of intensity-modulated arc therapy (IMAT) versus fixed-gantry intensity-modulated radiotherapy (IMRT) in the treatment of cervical esophageal cancer. Methods: Ten patients treated in our radiotherapy center were selected for this study. Based on the identical CT and planning target volume (PTV), two IMAT plans were generated with Eclipse ver 8.6 planning system. IMAT1 consisting of a single 359.8 degree rotation, and IMAT2 consisting of two coplanar 359.8 degree rotations. PTV were prescribed to 60 Gy in 30 fractions. Planning objectives for PTV, corresponding with the IMRT plans, were V98 larger than 97% and V110 no more than 15%. The maximum dose of spinal-cord was constrained below 45 Gy. One-way ANOVA were applied to dose-volume values for PTV and OAR from DVH. Results: There were no significant differences between IMRT and IMAT in PTV D98, V98, CI or total-lung V5, V10, V30, V40, V50 and mean lung dose (all P > 0.05). However, the differences were significant in terms of D2, V110 and HI of PTV, V20 of the total-lung (all P1 =709.7 MU, and IMAT2 =803.8 MU (F =39.25, P =0.000). On the treatment time, IMRT= 14.9 min, IMAT1 = 1.9 min, and IMAT2 =2.66 min (F=45.14, P=0.000). Conclusions: IMAT is equal to IMRT in dosimetric evaluation. Due to much less MU and delivery time, IMAT is an ideal technique in treating patients by reducing the uncomfortable influences which could effect the treatment. However, IMAT1 is slightly inferior to IMAT2 (authors)

  15. Summary Report on the Coordinated Research Project (CRP) on Implementation of the International Code of Practice on Dosimetry in Diagnostic Radiology Technical Reports Series No. 457 at Secondary Standard Dosimetry Laboratories and Hospitals

    The CRP to review the effectiveness of the implementation of the Technical Reports Series No. 457 (TRS 457) both in the SSDL and clinical environment ran from 2005 - 2008, with 11 participants; 7 being primarily from SSDLs and 4 from clinical centres. The specific objectives of the CRP were (i) to test the establishment of calibration facilities for diagnostic X rays and the calibration of selected instruments; (ii) to test measurement procedures with phantoms and on patients in hospitals; and (iii) the publication of the results of experiments as well as suggestions for the practical implementation of the procedures described in the Technical Reports Series No. 457. Seven activities were undertaken to achieve the above objectives as seen below. Activities SSDLs (i) Establishment of calibration facility following guidelines in the TRS 457. This includes calibration beams and procedures: All seven participants in the project from SSDLs, successfully established beam qualities and procedures for the calibration of diagnostic radiology dosimeters. This demonstrated that TRS 457 gave a clear guidance for calibration laboratories. (ii) Establishment of uncertainty budget for SSDLs calibrations. Uncertainty budgets were established for 6 of the participants. (iii) Comparison of calibration of diagnostic dosimeters and kVp meters. A comparison of calibration coefficients through exchange of ionization chambers was made by all seven SSDLs. The derived NK coefficients at certain RQR beam qualities from different SSDLs (except in one case) were within the relevant uncertainties. This comparison confirms the ability of the participants to setup the calibration infrastructure in diagnostic X rays. No comparison of kVp meters was made - see section on effectiveness. Hospitals (i) Implementation of measurements procedures for dosimetry in general radiography, fluoroscopy, mammography, computed tomography and dental radiography. This includes measurements with phantoms as well as

    Hospitals and health care institutions are facing the challenge of improving the quality of their services while reducing their costs. The current study presents the application of operations management practices in a dermatology oncology outpatient clinic specialized in skin cancer treatment. An interesting alternative considered by the clinic is the implementation of a one-stop-shop concept for the treatment of new patients diagnosed with basal cell carcinoma. This alternative proposes a significant improvement in the average waiting time that a patient spends between the diagnosis and treatment. This study is focused on the identification of factors that influence the average throughput time of patients treated in the clinic from the logistic perspective. A two-phase approach was followed to achieve the goals stated in this study. The first phase included an integrated approach for the deterministic analysis of the capacity using a demand-supply model for the hospital processes, while the second phase involved the development of a simulation model to include variability to the activities involved in the process and to evaluate different scenarios. Results showed that by managing three factors: the admission rule, resources allocation and capacity planning in the dermato-oncology unit throughput times for treatments of new patients can be decreased with more than 90 %, even with the same resource level. Finally, a pilot study with 16 patients was also conducted to evaluate the impact of implementing the one stop shop concept from a clinical perspective. Patients turned out to be satisfied with the fast diagnosis and treatment. PMID:22961383

    The Austrian Breast Cancer Early Detection Program (BKFP) has officially started in January 2014. In order to ensure that all participating women can rely on a sufficient cancer detection rate while at the same time the required dose is as low as reasonably achievable, all participating radiology institutes (approx. 200) have to fulfill strict quality assurance requirements. The control and certification is performed by the Reference Center for Technical Quality Assurance (RefZQS), which has been developing the methods and tolerances in a pilot project since 2007. The limits are defined in the EUREF-Oeprotocol which is based on the European EPQC guidelines. From the requirement for optimized image quality while simultaneously following the ALARA principle, we found modality-dependent dose requirements, which we had expected but which have now been compiled for the first time for Austria.

    all parts of the Secretariat. Nuclear medicine projects increased the availability of cancer diagnosis and treatment and improved the radiation protection of patients and technicians. Local consumption and export of crops from developing countries have been increased with support from the Agency through the use of the sterile insect technique as well as improved varieties of fruits and legumes resistant to disease and drought. Achievements in identifying water resources and mapping aquifer flows were also made using isotope hydrology methods. In the Europe region, the Agency contributed to returning high enriched uranium fuel to the country of origin and converting research reactor fuel to low-enriched uranium. In addition, upgrading radiation protection infrastructures in all regions has had continued success. The year had many accomplishments, as well as challenges. Early in 2003, the severe acute respiratory syndrome (SARS) erupted in the East Asia and the Pacific region, halting workshops and training sessions for a period of time. Security-related issues also hampered programme implementation in several regions. In addition, the unpredictability of payments to the Technical Cooperation Fund put into question the implementation of the full programme planned for 2003-2004. As a result of a shortfall in resources to the Technical Cooperation Fund at the end of 2003, the 2004 technical cooperation programme had to be reduced and the Board was asked to authorize an increase in over programming to 20% through June 2004.Thanks to significant efforts by a number of Member States during the first quarter of 2004, additional payments to the Technical Cooperation Fund for 2003 were made, resulting in a rate of attainment of 86.8% as of 31 March 2004. In addition, Member States made efforts to pay their target shares for 2004 earlier than has been the practice in the past. This permitted the Secretariat to restore many of the activities that had been postponed or cancelled

    Patients with castration-resistant prostate cancer (CRPC) can be treated with abiraterone, a potent inhibitor of androgen synthesis, or enzalutamide, a second-generation androgen receptor (AR) antagonist, both targeting AR signaling. However, most patients relapse after several months of therapy and a majority of patients with relapsed CRPC tumors express the AR target gene prostate-specific antigen (PSA), suggesting that AR signaling is reactivated and can be targeted again to inhibit the relapsed tumors. Novel small molecules capable of inhibiting AR function may lead to urgently needed therapies for patients resistant to abiraterone, enzalutamide, and/or other previously approved antiandrogen therapies. Here, we describe a high-throughput high-content screening (HCS) campaign to identify small-molecule inhibitors of AR nuclear localization in the C4-2 CRPC cell line stably transfected with GFP-AR-GFP (2GFP-AR). The implementation of this HCS assay to screen a National Institutes of Health library of 219,055 compounds led to the discovery of 3 small molecules capable of inhibiting AR nuclear localization and function in C4-2 cells, demonstrating the feasibility of using this cell-based phenotypic assay to identify small molecules targeting the subcellular localization of AR. Furthermore, the three hit compounds provide opportunities to develop novel AR drugs with potential for therapeutic intervention in CRPC patients who have relapsed after treatment with antiandrogens, such as abiraterone and/or enzalutamide.

  1. TH-C-12A-07: Implementation of a Pulsed Low Dose Date Radiotherapy (PLRT) Protocol for Recurrent Cancers Using Advanced Beam Delivery

    International Nuclear Information System (INIS)

    Purpose: Recent in vitro and in vivo experimental findings provided strong evidence that pulsed low-dose-rate radiotherapy (PLDR) produced equivalent tumor control as conventional radiotherapy with significantly reduced normal tissue toxicities. This work aimed to implement a PLDR clinical protocol for the management of recurrent cancers utilizing IMRT and VMAT. Methods: Our PLDR protocol requires that the daily 2Gy dose be delivered in 0.2Gy×10 pulses with a 3min interval between the pulses. To take advantage of low-dose hyper-radiosensitivity the mean dose to the target is set at 0.2Gy and the maximum dose is limited to 0.4Gy per pulse. Practical planning strategies were developed for IMRT and VMAT: (1) set 10 ports for IMRT and 10 arcs for VMAT with each angle/arc as a pulse; (2) set the mean dose (0.2Gy) and maximum dose (0.4Gy) to the target per pulse as hard constraints (no constraints to OARs); (3) select optimal port/arc angles to avoid OARs; and (4) use reference structures in or around target/OARs to reduce maximum dose to the target/OARs. IMRT, VMAT and 3DCRT plans were generated for 60 H and N, breast, lung, pancreas and prostate patients and compared. Results: All PLDR treatment plans using IMRT and VMAT met the dosimetry requirements of the PLDR protocol (mean target dose: 0.20Gy±0.01Gy; maximum target dose < 0.4Gy). In comparison with 3DCRT, IMRT and VMAT exhibited improved target dose conformity and OAR dose sparing. A single arc can minimize the difference in the target dose due to multi-angle incidence although the delivery time is longer than 3DCRT and IMRT. Conclusion: IMRT and VMAT are better modalities for PLDR treatment of recurrent cancers with superior target dose conformity and critical structure sparing. The planning strategies/guidelines developed in this work are practical for IMRT/VMAT treatment planning to meet the dosimetry requirements of the PLDR protocol

Practical planning strategies were developed for IMRT and VMAT: (1) set 10 ports for IMRT and 10 arcs for VMAT with each angle/arc as a pulse; (2) set the mean dose (0.2Gy) and maximum dose (0.4Gy) to the target per pulse as hard constraints (no constraints to OARs); (3) select optimal port/arc angles to avoid OARs; and (4) use reference structures in or around target/OARs to reduce maximum dose to the target/OARs. IMRT, VMAT and 3DCRT plans were generated for 60 H and N, breast, lung, pancreas and prostate patients and compared. Results: All PLDR treatment plans using IMRT and VMAT met the dosimetry requirements of the PLDR protocol (mean target dose: 0.20Gy±0.01Gy; maximum target dose < 0.4Gy). In comparison with 3DCRT, IMRT and VMAT exhibited improved target dose conformity and OAR dose sparing. A single arc can minimize the difference in the target dose due to multi-angle incidence although the delivery time is longer than 3DCRT and IMRT. Conclusion: IMRT and VMAT are better modalities for PLDR treatment of recurrent cancers with superior target dose conformity and critical structure sparing. The planning strategies/guidelines developed in this work are practical for IMRT/VMAT treatment planning to meet the dosimetry requirements of the PLDR protocol.

  3. Intensity modulated arc therapy implementation in a three phase adaptive 18F-FDG-PET voxel intensity-based planning strategy for head-and-neck cancer

    International Nuclear Information System (INIS)

    This study investigates the implementation of a new intensity modulated arc therapy (IMAT) class solution in comparison to a 6-static beam step-and-shoot intensity modulated radiotherapy (s-IMRT) for three-phase adaptive 18F-FDG-PET-voxel-based dose-painting-by-numbers (DPBN) for head-and-neck cancer. We developed 18F-FDG-PET-voxel intensity-based IMAT employing multiple arcs and compared it to clinically used s-IMRT DPBN. Three IMAT plans using 18F-FDG-PET/CT acquired before treatment (phase I), after 8 fractions (phase II) and CT acquired after 18 fractions (phase III) were generated for each of 10 patients treated with 3 s-IMRT plans based on the same image sets. Based on deformable image registration (ABAS, version 0.41, Elekta CMS Software, Maryland Heights, MO), doses of the 3 plans were summed on the pretreatment CT using validated in-house developed software. Dosimetric indices in targets and organs-at-risk (OARs), biologic conformity of treatment plans set at ≤5 %, treatment quality and efficiency were compared between IMAT and s-IMRT for the whole group and for individual patients. Doses to most organs-at-risk (OARs) were significantly better in IMAT plans, while target levels were similar for both types of plans. On average, IMAT ipsilateral and contralateral parotid mean doses were 14.0 % (p = 0.001) and 12.7 % (p < 0.001) lower, respectively. Pharyngeal constrictors D50% levels were similar or reduced with up to 54.9 % for IMAT compared to s-IMRT for individual patient cases. IMAT significantly improved biologic conformity by 2.1 % for treatment phases I and II. 3D phantom measurements reported an agreement of ≥95 % for 3 % and 3 mm criteria for both treatment modalities. IMAT delivery time was significantly shortened on average by 41.1 %. IMAT implementation significantly improved the biologic conformity as compared to s-IMRT in adaptive dose-escalated DPBN treatments. The better OAR sparing and faster delivery highly improved the treatment

  4. The technical feasibility of an image-guided intensity-modulated radiotherapy (IG-IMRT) to perform a hypofractionated schedule in terms of toxicity and local control for patients with locally advanced or recurrent pancreatic cancer

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the technical feasibility of an image-guided intensity modulated radiotherapy (IG-IMRT) using involved-field technique to perform a hypofractionated schedule for patients with locally advanced or recurrent pancreatic cancer. From May 2009 to November 2011, 12 patients with locally advanced or locally recurrent pancreatic cancer received hypofractionated CCRT using TomoTherapy Hi-Art with concurrent and sequential chemotherapy at Seoul St. Mary’s Hospital, the Catholic University of Korea. The total dose delivered was 45 Gy in 15 fractions or 50 Gy in 20 fractions. The target volume did not include the uninvolved regional lymph nodes. Treatment planning and delivery were performed using the IG-IMRT technique. The follow-up duration was a median of 31.1 months (range: 5.7-36.3 months). Grade 2 or worse acute toxicities developed in 7 patients (58%). Grade 3 or worse gastrointestinal and hematologic toxicity occurred in 0% and 17% of patients, respectively. In the response evaluation, the rates of partial response and stable disease were 58% and 42%, respectively. The rate of local failure was 8% and no regional failure was observed. Distant failure was the main cause of treatment failure. The progression-free survival and overall survival durations were 7.6 and 12.1 months, respectively. The involved-field technique and IG-IMRT delivered via a hypofractionated schedule are feasible for patients with locally advanced or recurrent pancreatic cancer

    Operational Experience At the end of the first full-year running period of LHC, CMS is established as a reliable, robust and mature experiment. In particular common systems and infrastructure faults accounted for <0.6 % CMS downtime during LHC pp physics. Technical operation throughout the entire year was rather smooth, the main faults requiring UXC access being sub-detector power systems and rack-cooling turbines. All such problems were corrected during scheduled technical stops, in the shadow of tunnel access needed by the LHC, or in negotiated accesses or access extensions. Nevertheless, the number of necessary accesses to the UXC averaged more than one per week and the technical stops were inevitably packed with work packages, typically 30 being executed within a few days, placing a high load on the coordination and area management teams. It is an appropriate moment for CMS Technical Coordination to thank all those in many CERN departments and in the Collaboration, who were involved in CMS techni...

    Operational Experience Since the closure of the detector in February, the technical operation of CMS has been quite smooth and reliable. Some minor interventions in UXC were required to cure failures of power supplies, fans, readout boards and rack cooling connections, but all these failures were repaired in scheduled technical stops or parasitically during access dedicated to fixing LHC technical problems. The only occasion when CMS had to request an access between fills was to search for the source of an alarm from the leak-detection cables mounted in the DT racks. After a few minutes of diagnostic search, a leaking air-purge was found. Replacement was complete within 2 hours. This incident demonstrated once more the value of these leak detection cables; the system will be further extended (during the end of year technical stop) to cover more racks in UXC and the floor beneath the detector. The magnet has also been operating reliably and reacted correctly to the 14s power cut on 29 May (see below). In or...

    Lung cancer is the leading cause of cancer death in the United States and other industrialised countries. The most important risk factor is active smoking. However, given the increased incidence of lung cancer in non-smokers, it is necessary to improve knowledge regarding other risk factors. Radon (Rn) is a noble gas and is the most important natural source of human exposure to ionizing radiation. Exposure to high levels of this radioactive gas is related to an increased risk of developing lu...

  9. Technical safety

    International Nuclear Information System (INIS)

    Technical risks are compared to the publically consciously or unconsciously accepted risks. This kind of risk analysis has the aim to achieve an optimum safety with a justifiable effort. The realization of this target requires the solving of technical, economic and sociopolitical problems. In order to minimize the risk, one can reduce the probability of occurence as well as the extent of damage. Risk situations for the population due to natural occurences such as earthquakes, strike of lightning, frost, high water etc. can be relatively well quantified. These are therefore suitable a a basis for comparison. This basis risk is increased by individual traffic and by human force effects such as terror and war. On the other hand, life in the neighbourhood of a nuclear power plant does not measurably contribute to increasing individual risk. In principle, by increased expenditure one can reduce technical risks. Due to the lack of means, one must then save correspondingly somewhere else. The safety risks there can then possibly increase overproportionally or at least the wide-spread desire for a higher standard of living cannot be fulfilled. Nevertheless, absolute safety can never be reached. The insurance business is responsible for covering the financial damage. Fault trees are used in technology to analyse the weak points. This is explained taking the example of a propylene low-temperature tank. If one keeps below the base risk it must be possible to build technical plants, even nuclear power plants, in densely populated areas. Technical safety analyses, however, only embrace one side of it, rigid building and material control and extensive elimination of human error ar just as important. (orig.)

Overview of the extended Technical Stop  The principal objectives of the extended Technical Stop affecting the detector itself were the installation of the TOTEM T1 telescopes on both ends, the readjustment of the alignment link-disk in YE-2, the replacement of the light-guide sleeves for all PMs of both HFs, and some repairs on TOTEM T2 and CASTOR. The most significant tasks were, however, concentrated on the supporting infrastructure. A detailed line-by-line leak search was performed in the C6F14 cooling system of the Tracker, followed by the installation of variable-frequency drives on the pump motors of the SS1 and SS2 tracker cooling plants to reduce pressure transients during start-up.

    Overview From a technical perspective, CMS has been in “beam operation” state since 6th November. The detector is fully closed with all components operational and the magnetic field is normally at the nominal 3.8T. The UXC cavern is normally closed with the radiation veto set. Access to UXC is now only possible during downtimes of LHC. Such accesses must be carefully planned, documented and carried out in agreement with CMS Technical Coordination, Experimental Area Management, LHC programme coordination and the CCC. Material flow in and out of UXC is now strictly controlled. Access to USC remains possible at any time, although, for safety reasons, it is necessary to register with the shift crew in the control room before going down.It is obligatory for all material leaving UXC to pass through the underground buffer zone for RP scanning, database entry and appropriate labeling for traceability.

  18. Recommendations for implementing stereotactic radiotherapy in peripheral stage IA non-small cell lung cancer: report from the Quality Assurance Working Party of the randomised phase III ROSEL study

    International Nuclear Information System (INIS)

    A phase III multi-centre randomised trial (ROSEL) has been initiated to establish the role of stereotactic radiotherapy in patients with operable stage IA lung cancer. Due to rapid changes in radiotherapy technology and evolving techniques for image-guided delivery, guidelines had to be developed in order to ensure uniformity in implementation of stereotactic radiotherapy in this multi-centre study. A Quality Assurance Working Party was formed by radiation oncologists and clinical physicists from both academic as well as non-academic hospitals that had already implemented stereotactic radiotherapy for lung cancer. A literature survey was conducted and consensus meetings were held in which both the knowledge from the literature and clinical experience were pooled. In addition, a planning study was performed in 26 stage I patients, of which 22 were stage 1A, in order to develop and evaluate the planning guidelines. Plans were optimised according to parameters adopted from RTOG trials using both an algorithm with a simple homogeneity correction (Type A) and a more advanced algorithm (Type B). Dose conformity requirements were then formulated based on these results. Based on current literature and expert experience, guidelines were formulated for this phase III study of stereotactic radiotherapy versus surgery. These guidelines can serve to facilitate the design of future multi-centre clinical trials of stereotactic radiotherapy in other patient groups and aid a more uniform implementation of this technique outside clinical trials

      Operational experience 2011 CMS is approaching the end of a very successful year of operation. Proton- proton running ended in the late afternoon of 30th October with a stunning 5.73 fb–1 delivered by LHC, of which CMS recorded 5.22 fb–1. During heavy-ion operation, which continues until 7th December, both the accelerator and the CMS detector have also performed very well. Despite the encouraging overall reliability of technical operation, several infrastructure failures which occurred since the last Bulletin are worthy of mention, with one leading for the first time to significant data-loss. On 10th July, a CERN-wide power failure brought down essentially all services including the magnet, due to an MCS setting being left in “manual” after the recent technical stop, but there was no significant damage and the detector was operational before the LHC, despite a slow and tortuous recovery (one of several indications this year that there is room for improve...

    For the reporting period, the CMS common systems and infrastructure worked well, without failures that caused significant data losses. One more disconnection of the magnet cold box occurred in the shadow of interruptions in data taking, caused by a series of technical faults. The recognition during 2012 that re-connection can only safely be done at around 2 T implies a minimum magnet recovery time of 12 hours and raises serious concerns about the number of ramping cycles of the magnet these incidents cause. This has triggered studies of how to make the cryo-system of the magnet more robust against failures. The proton-proton run ended just before the end-of-year CERN closure, during which CASTOR was installed on the negative end of CMS and both ZDC calorimeters were installed in TAN absorbers the LHC tunnel, in preparation for the heavy-ion run. The installation of CASTOR was an excellent “engineering test” of procedures for working in an activated environment. Despite some technical pr...

Fundamental technical description of devices used have been reported elsewhere. We included alterations and implementation of these biophotonic instruments as applied to our objectives. We disassociated human tumor and submitted the cells to optical characterization to support our working hypothesis of stem cell origins to cancer and mechanisms. Single cell combined with population based analysis within the Pancreatic cancer system led us to information regarding the polarization state of cells possessing anchor proteins and drug influx pumps. Multispectral imaging combined with flow cytometry enabled us to target rare cells that appear to retain template DNA. rendering them resistant to anti-cancer drug therapy. In this study we describe an optical method that combines high-throughput population pattern and correlates each cell with an individual fluorescent and bright-field image.

    Full Text Available The aim of this study is to evaluate the modular educational program implemented at vocational high schools and to describe the problems in this program. The study is based on the Erden’s Evaluation Model Regarding Curriculum Components. The model of the study is descriptive study. The data were gathered through two different models by using three different sources: The quantitative data were collected from 430 teachers and 903 students at 48 vocational and technical high schools in Turkey. The questionnaires developed by the researcher were given to collect the quantitative data from teachers and students. In order to analyze the data, computer data analysis program was used. When there is a normal distribution independent sample and paired sample t tests and when there is not a normal distribution, Mann Whitney U and Wilcoxon tests were conducted. The qualitative data were gathered from 15 specialists working at Ministry of National Education and universities. Semi-structured interview forms were used to collect this type of data. The findings of this study are: The objectives of the modular educational program implemented at vocational high schools are clear, comprehensible and can be expressed behaviorally. At the same time, the objectives of the program are preparing the students to their jobs. Some modules have a rich knowledge transition which contradicts with the notion of this program. The activities related with teaching and learning process are partially sufficient. However, the teaching-learning process cannot be achieved because of some regulation problems. The most important problem in the evaluation part of the program is the rules and regulations being effect. If some changes are done in the rules and regulations, the evaluation part of the program could be more effective. According to this, it may be beneficial to make the practices of vocational analysis constant, place modules appropriate for contemporary vocations in the

    Overview Once again, the bulk of this article reviews the intense activity of a recently completed shutdown, which, although quite unforeseeable until a few weeks before it started, proved by its success that our often advertised capability to conduct major maintenance within a two month period is real. Although safely completed, on-time to remarkable precision, the activity was not without incident, and highlighted our dependence on many experienced, specialist teams and their precise choreography. Even after the yoke was safely closed, magnet re-commissioning and beampipe pumpdown showed new and thought-provoking behaviour. The struggle to maintain adequate technical resources will be a pre-occupation over the coming months, in parallel with the start of truly sustained operation, for which various procedures are still being put in place. Planning for future shutdowns must now become a high priority, with many working groups and task forces already in existence to prepare infrastructure improvements and to...

    Full Text Available Social, political, and economic factors are directly and indirectly associated with the quality and distribution of health resources across Canada. First Nations (FN women in particular endure a disproportionate burden of ill health in contrast to the mainstream population. The complex relationship of health, social, and historical determinants are inherent to increased cervical cancer in FN women. This can be traced back to the colonial oppression suffered by Canadian FN and the social inequalities they have since faced. Screening - the Papinacolaou (Pap test – and early immunization have rendered cervical cancer almost entirely preventable but despite these options, FN women endure notably higher rates of diagnosis and mortality due to cervical cancer. The Anishinaabek Cervical Cancer Screening Study (ACCSS is a participatory action research project investigating the factors underlying the cervical cancer burden in FN women. ACCSS is a collaboration with 11 FN communities in Northwest Ontario, Canada and a multidisciplinary research team from across Canada with expertise in cancer biology, epidemiology, medical anthropology, public health, virology, women’s health, and pathology. Interviews with healthcare providers and community members revealed that prior to any formal data collection education must be offered. Consequently, an educational component was integrated into the existing quantitative design of the study: a two-armed, community-randomized trial that compares the uptake of two different cervical screening modalities. In ACCSS, the Research Team integrates community engagement and the flexible nature of participatory research with the scientific rigor of a randomized controlled trial. ACCSS findings will inform culturally appropriate screening strategies, aiming to reduce the disproportionate burden of cervical disease in concert with priorities of the partner FN communities.

  2. U.S. technical specification improvement program

    International Nuclear Information System (INIS)

    The U.S. Nuclear Community has underway an extensive Technical Specification improvement effort. The overall goal of the effort is to improve operational safety by simplifying the Technical Specifications, making them more usable by the operators, and providing a clear link between the technical requirements and their safety significance. This will allow the operators and plant staff to focus on the more risk significant requirements. General improvements are being made to both the overall format and content of Technical Specifications as well as to specific technical requirements within the specifications. The focal point for making these improvements is the recently issued Commission Policy Statement on Technical Specification Improvements. Implementing this Policy Statement will result in new Standard Technical Specifications for each of the four U.S. nuclear steam supply system vendors, new standards which we believe will be adopted at a significant number of the nuclear power plants in our country. This presentation briefly describes some of the Technical Specification problems encountered, some of the studies that were done and recommendations that were made to correct these problems. Details are given about the NRC Policy Statement on Technical Specification Improvements and how it will be implemented

    This study presents our preliminary work of the computed tomography (CT) image guided brachytherapy (IGBT) implementation on cervical cancer patients. We developed a protocol in which patients undergo two Magnetic Resonance Imaging (MRI) examinations; a) prior to external beam radiotherapy (EBRT) and b) prior to intra-cavitary brachytherapy for tumour identification and delineation during IGBT planning and dosimetry. For each fraction, patients were simulated using CT simulator and images were transferred to the treatment planning system. The HR-CTV, IR-CTV, bladder and rectum were delineated on CT-based contouring for cervical cancer. Plans were optimised to achieve HR-CTV and IR-CTV dose (D90) of total EQD2 80Gy and 60Gy respectively, while limiting the minimum dose to the most irradiated 2cm3 volume (D2cc) of bladder and rectum to total EQD2 90Gy and 75Gy respectively. Data from seven insertions were analysed by comparing the volume-based with traditional point- based doses. Based on our data, there were differences between volume and point doses of HR- CTV, bladder and rectum organs. As the number of patients having the CT-based IGBT increases from day to day in our centre, it is expected that the treatment and dosimetry accuracy will be improved with the implementation.

  9. A Technical Assessment of the Utility of Reverse Phase Protein Arrays for the Study of the Functional Proteome in Non-microdissected Human Breast Cancers.

    Hennessy, Bryan T

    2010-12-01

    INTRODUCTION: The lack of large panels of validated antibodies, tissue handling variability, and intratumoral heterogeneity potentially hamper comprehensive study of the functional proteome in non-microdissected solid tumors. The purpose of this study was to address these concerns and to demonstrate clinical utility for the functional analysis of proteins in non-microdissected breast tumors using reverse phase protein arrays (RPPA). METHODS: Herein, 82 antibodies that recognize kinase and steroid signaling proteins and effectors were validated for RPPA. Intraslide and interslide coefficients of variability were <15%. Multiple sites in non-microdissected breast tumors were analyzed using RPPA after intervals of up to 24 h on the benchtop at room temperature following surgical resection. RESULTS: Twenty-one of 82 total and phosphoproteins demonstrated time-dependent instability at room temperature with most variability occurring at later time points between 6 and 24 h. However, the 82-protein functional proteomic "fingerprint" was robust in most tumors even when maintained at room temperature for 24 h before freezing. In repeat samples from each tumor, intratumoral protein levels were markedly less variable than intertumoral levels. Indeed, an independent analysis of prognostic biomarkers in tissue from multiple tumor sites accurately and reproducibly predicted patient outcomes. Significant correlations were observed between RPPA and immunohistochemistry. However, RPPA demonstrated a superior dynamic range. Classification of 128 breast cancers using RPPA identified six subgroups with markedly different patient outcomes that demonstrated a significant correlation with breast cancer subtypes identified by transcriptional profiling. CONCLUSION: Thus, the robustness of RPPA and stability of the functional proteomic "fingerprint" facilitate the study of the functional proteome in non-microdissected breast tumors.

      UXC + detectors As explained in detail in the November 2011 bulletin, the bellows unit at −18.5 m from the CMS interaction point was identified as a prime candidate for the regularly occurring pressure spikes which occasionally led to sustained severe background conditions in 2011, affecting dead time and data quality. Similar regions in LHC with vacuum instabilities were observed to be close to bellows, which radiography showed to have distorted RF-fingers — on removal, they proved to have been severely overheated. The plans for the Year-End Technical Stop were adapted to prioritise radiography of the bellows at 16 m to 18 m either end of CMS. Excellent work by the beam pipe, survey and heavy mechanical teams allowed the X-rays to be taken as planned on 20th December, showing that the bellow at −18.5m had an obvious non-conformity. The RF-fingers were found inside the end of the opposing flared pipe instead of outside. In addition, the overlap between fingers and...

    Cancer patients face a myriad of psychosocial and practical issues. Especially challenging is the time from an initial diagnosis to the onset of treatment and patient navigation services are important to guide patients, especially underserved populations, through this maze of uncertainty. Here we report on the Pennsylvania Patient Navigator Demonstration Project (PaPND) designed to evaluate the acceptability, feasibility, and impact of a culturally and linguistically appropriate non-clinical navigator program. The development of the project, based on behavioral theory and community-based participatory research principles, is described. Forty-four cancer patients from diverse backgrounds participated, which included a baseline assessment, navigation services, and a four week and twelve week follow-up assessment. On average, participants experienced 1.8 barriers with transportation and insurance issues the most common barriers. The majority (56%) of the barriers required more than an hour of the navigator's time to address, with insurance, transportation and caregiver/support issues requiring the most time. Overall patients were fairly satisfied with the navigation services. The findings showed improvement patient's stress-related thoughts, cognition (understanding of their disease), expectancies and beliefs or values/goals, as well as self-efficacy of managing cancer related issues from the baseline to follow-up assessments. The evaluation results suggest that providing and connecting cancer patients to appropriate information to improve their understanding of their diagnosis and recommended treatments needs to be addressed, and where the integration of non-clinical and clinical navigation is essential. In addition, more attention to the assessment of psychosocial issues, such as the patients' emotional worries, and more comprehensive training in these areas would enhance navigation programs.

  18. Consequences of anorectal cancer atlas implementation in the cooperative group setting: Radiobiologic analysis of a prospective randomized in silico target delineation study

    International Nuclear Information System (INIS)

    Purpose: The aim of this study is to ascertain the subsequent radiobiological impact of using a consensus guideline target volume delineation atlas. Materials and methods: Using a representative case and target volume delineation instructions derived from a proposed IMRT rectal cancer clinical trial, gross tumor volume (GTV) and clinical/planning target volumes (CTV/PTV) were contoured by 13 physician observers (Phase 1). The observers were then randomly assigned to follow (atlas) or not-follow (control) a consensus guideline/atlas for anorectal cancers, and instructed to re-contour the same case (Phase 2). Results: The atlas group was found to have increased tumor control probability (TCP) after the atlas intervention for both the CTV (p < 0.0001) and PTV1 (p = 0.0011) with decreasing normal tissue complication probability (NTCP) for small intestine, while the control group did not. Additionally, the atlas group had reduced variance in TCP for all target volumes and reduced variance in NTCP for the bowel. In Phase 2, the atlas group had increased TCP relative to the control for CTV (p = 0.03). Conclusions: Visual atlas and consensus treatment guideline usage in the development of rectal cancer IMRT treatment plans reduced the inter-observer radiobiological variation, with clinically relevant TCP alteration for CTV and PTV volumes

  6. Design and implementation of a rotational radiotherapy technique for breast cancer treatment and their comparison with 3-D-Crt irradiation technique

    International Nuclear Information System (INIS)

    Breast cancer is one of oncological diseases worldwide, as well in Mexico, which causes even more deaths than cervical cancer; this condition is the second death cause in women aged 30-54 years and threatens all socio-economic groups. The treatment is highly dependent on the stage which is detected and based on protocols that include a combination of surgery, chemotherapy and radiotherapy. This paper studies the main irradiation technique for patients with mastectomy, breast full cycle (irradiation of the chest well and supraclavicular nodes) in their mode Three Dimensional - Conformal Radiation Therapy (3-D-Crt), and compared with the Volumetric Modulated Arc Therapy (VMAT) technique proposed in this paper. In both techniques the prescription was 50 Gy divided into 25 fractions. The techniques were applied in three female patients (being an initial study) with disease of the left side, the target volume and organs at risk were delineated by the medical treating radiation oncologist, the planning system used was Eclipse version 10; for quantitative comparison of both plans indexes of homogeneity were used, con formality, the target volume coverage and normal tissue, sub factors and overdosing, the conformation number and coverage quality. They were evaluated and compared the media, maximum and minimum dose of the organs at risk, based on the fact that the coverage of the target volume, dose gradient and dose at risk organs are acceptable (prescription dose greater that 90% coverage, gradient less that 20% and organs at risk in accordance with the Quantec limitations for both versions).

  7. Does obesity hinder radiotherapy in endometrial cancer patients? The implementation of new techniques in adjuvant radiotherapy – focus on obese patients

    Directory of Open Access Journals (Sweden)

    Małgorzata Moszyńska-Zielińska

    2014-05-01

    Full Text Available The increasing incidence of obesity in Poland and its relation to endometrioid endometrial cancer (EEC is resulting in the increasing necessity of treating obese women. Treatment of an overweight patient with EEC may impede not only the surgical procedures but also radiotherapy, especially external beam radiotherapy (EBRT. The problems arise both during treatment planning and when delivering each fraction due to the difficulty of positioning such a patient – it implies the danger of underdosing targets and overdosing organs at risk. Willingness to use dynamic techniques in radiation oncology has increased for patients with EEC, even those who are obese. During EBRT careful daily verification is necessary for both safety and treatment accuracy. The most accurate method of verification is cone beam computed tomography (CBCT with soft tissue assessment, although it is time consuming and often requires a radiation oncologist. In order to improve the quality of such treatment, the authors present the practical aspects of planning and treatment itself by means of dynamic techniques in EBRT. The authors indicate the advantages and disadvantages of different types of on-board imaging (OBI verification images. Considering the scanty amount of literature in this field, it is necessary to conduct further research in order to highlight proper planning and treatment of obese endometrial cancer patients. The review of the literature shows that all centres that wish to use EBRT for gynaecological tumours should develop their own protocols on qualification, planning the treatment and methods of verifying the patients’ positioning.

    Full Text Available Background Invasive fungal infections (IFI represent a serious threat for severely immunocompromised patients. Infection control interventions, including protective environment (PE implementation, are essential to reduce IFI incidence, mortality and burden of hospitalization, among high-risk patients. Information about the impact of these strategies in cancer patients with chemotherapy-induced neutropenia (CIN, in developing countries, is insufficient. Objectives To assess the impact of PE implementation on IFI incidence, consumption and cost of antifungal treatment, in a general, tertiary teaching hospital, in Southern Brazil. Patients and Methods We conducted a quasi-experimental study to evaluate an institutional intervention, in a hospital ward, for patients with CIN, which consisted in renovation of the ward and measures involving air-quality technologies installation, the main one being high efficiency particulate air (HEPA filters. Simultaneously, infection control routines were implemented. Neutropenic patients, admitted to any other hospital ward, prior to the renovation, were included in the historical control group. The IFI incidence was defined, according to the criteria proposed by the European Organization for Research and Treatment of Cancer. Direct costs of antifungal drugs were recorded, for all neutropenic patients. Results A total of 190 and 181 hospital admissions were included in the intervention and control groups, respectively. Total IFI incidence was reduced in the PE group (7.4% vs. 18.2%; P = 0.002 and the same was observed when considering only proven and probable IFI (1.6% vs. 8.3%; P = 0.003. This benefit persisted even after adjusting for antifungal prophylaxis (OR = 0.17; 95% CI = 0.05 ‒ 0.60. We observed a decreasing trend in molds and yeasts IFI incidence, in the intervention group. Although the final cost of antifungal agents was lower, after intervention (78347.37 USD vs. 154176.60 USD, the median cost per

  16. Automatic identification of organ/tissue regions in CT image data for the implementation of patient specific phantoms for treatment planning in cancer therapy

    Science.gov (United States)

    Sparks, Richard Blaine

    In vivo targeted radiotherapy has the potential to be an effective treatment for many types of cancer. Agents which show preferred uptake by cancerous tissue are labeled with radio-nuclides and administered to the patient. The preferred uptake by the cancerous tissue allows for the delivery of therapeutically effective radiation absorbed doses to tumors, while sparing normal tissue. Accurate absorbed dose estimation for targeted radiotherapy would be of great clinical value in a patient's treatment planning. One of the problems with calculating absorbed dose involves the use of geometric mathematical models of the human body for the simulation of the radiation transport. Since many patients differ markedly from these models, errors in the absorbed dose estimation procedure result from using these models. Patient specific models developed using individual patient's anatomical structure would greatly enhance the accuracy of dosimetry calculations. Patient specific anatomy data is available from CT or MRI images, but the very time consuming process of manual organ and tissue identification limits its practicality for routine clinical use. This study uses a statistical classifier to automatically identify organs and tissues from CT image data. In this study, image ``slices'' from thirty- five different subjects at approximately the same anatomical position are used to ``train'' the statistical classifier. Multi-dimensional probability distributions of image characteristics, such as location and intensity, are generated from the training images. Statistical classification rules are then used to identify organs and tissues in five previously unseen images. A variety of pre-processing and post-processing techniques are then employed to enhance the classification procedure. This study demonstrated the promise of statistical classifiers for solving segmentation problems involving human anatomy where there is an underlying pattern of structure. Despite the poor quality of

    Hackensack University Medical Center's major initiative to create a cleaner healthier and safer environment for patients, employees and the community served by the medical center is built on its commitment to protect the environment and conserve precious energy resources. Since 2004 the Medical Center launched a long term campaign to temper the negative environmental impact of proposed and existing new construction at the medical center and to improve campus wide overall energy efficiency. The plan was to begin by implementing a number of innovative and eco-friendly enhancements to the Gabrellian Women's and Children's Pavilion, in construction at the time, which would lead to Certification by the US Green Building Councils Leadership & Environmental Design (LEED) program. In addition the medical center would evaluate the feasibility of implementing a photovoltaic system in the new construction (in development and planned) to provide clean pollution free electricity. The steps taken to achieve this included conducting a feasibility study complete with architectural and engineering assessments to determine the potential for implementation of a photovoltaic system on the campus and also to conduct an energy survey that would focus on determining specific opportunities and upgrades that would lead to a healthier energy efficient interior environment at the medical center. The studies conducted by the medical center to determine the viability of installing a photovoltaic system identified two key issues that factored into leaderships decision not to implement the solar powered system. These factors were related to the advanced phase of construction of the women's and children's pavilion and the financial considerations to redesign and implement in the ambulatory cancer center. The medical center, in spite of their inability to proceed with the solar aspect of the project upheld their commitment to create a healthier environment for the patients

Weston, Inc. (RFW), Sergent, Hauskins ampersand Beckwith Agra, Inc. (SHB Agra), and Geraghty ampersand Miller, Inc. (G ampersand M)]. The first three companies have worked together effectively on the UMTRA Project for more than 10 years. With the initiation of the UMTRA Groundwater Project in April 1991, a need arose to increase the TAC's groundwater technical breadth and depth, so G ampersand M was brought in to augment the team's capabilities. The TAC contract's scope is to provide technical, analytical, environmental, engineering, design, inspection, and management support services to the US Department of Energy (DOE) for both surface and groundwater projects. The TAC team continues to support the DOE in completing surface remedial actions and initiating groundwater remediation work for start-up, characterization, design, construction oversight, and remedial operations. A key feature of the TAC's management approach is the extensive set of communication systems implemented for the UMTRA Project. These systems assist all functional disciplines in performing UMTRA Project tasks associated with management, technical support, administrative support, and financial/project controls

  5. Consolidated incineration facility technical support

    International Nuclear Information System (INIS)

    In 1996, the Savannah River Site plans to begin operation of the Consolidated Incineration Facility (CIF) to treat solid and liquid RCRA hazardous and mixed wastes. The Savannah River Technology Center (SRTC) leads an extensive technical support program designed to obtain incinerator and air pollution control equipment performance data to support facility start-up and operation. Key components of this technical support program include recently completed waste burn tests at both EPA's Incineration Research Facility and at Energy and Environmental Research Corporation's Solid Waste Incineration Test Facility. The main objectives for these tests were determining the fate of heavy metals, measuring organics destruction and removal efficiencies, and quantifying incinerator offgas particulate loading and size distribution as a function of waste feed characteristics and incineration conditions. In addition to these waste burning tests, the SRTC has recently completed installations of the Offgas Components Test Facility (OCTF), a 1/10 scale CIF offgas system pilot plant. This pilot facility will be used to demonstrate system operability and maintainability, evaluate and optimize equipment and instrument performance, and provide direct CIF start-up support. Technical support programs of this type are needed to resolve technical issues related with treatment and disposal of combustible hazardous, mixed, and low-level radioactive waste. Implementation of this program will minimize facility start-up problems and help insure compliance with all facility performance requirements

  6. Implementation of a Novel Algorithm For Generating Synthetic CT Images From Magnetic Resonance Imaging Data Sets for Prostate Cancer Radiation Therapy

    International Nuclear Information System (INIS)

    Purpose: To describe and evaluate a method for generating synthetic computed tomography (synCT) images from magnetic resonance simulation (MR-SIM) data for accurate digitally reconstructed radiograph (DRR) generation and dose calculations in prostate cancer radiation therapy. Methods and Materials: A retrospective evaluation was performed in 9 prostate cancer patients who had undergone MR-SIM in addition to CT simulation (CT-SIM). MR-SIM data were used to generate synCT images by using a novel, voxel-based weighted summation approach. A subset of patients was used for weight optimization, and the number of patients to use during optimization was determined. Hounsfield unit (HU) differences between CT-SIM and synCT images were analyzed via mean absolute error (MAE). Original, CT-based treatment plans were mapped onto synCTs. DRRs were generated, and agreement between CT and synCT-generated DRRs was evaluated via Dice similarity coefficient (DSC). Dose was recalculated, and dose-volume metrics and gamma analysis were used to evaluate resulting treatment plans. Results: Full field-of-view synCT MAE across all patients was 74.3 ± 10.9 HU with differences from CTs of 2.0 ± 8.1 HU and 11.9 ± 46.7 HU for soft tissue structures (prostate, bladder, and rectum) and femoral bones, respectively. Calculated DSCs for anterior-posterior and lateral DRRs were 0.90 ± 0.04 and 0.92 ± 0.05, respectively. Differences in D99%, mean dose, and maximum dose to the clinical target volume from CT-SIM dose calculations were 0.75% ± 0.35%, 0.63% ± 0.34%, and 0.54% ± 0.33%, respectively, for synCT-generated plans. Gamma analysis (2%/2 mm dose difference/distance to agreement) revealed pass rates of 99.9% ± 0.1% (range, 99.7%-100%). Conclusion: Generated synCTs enabled accurate DRR generation and dose computation for prostate MR-only simulation. Dose recalculated on synCTs agreed well with original planning distributions. Further validation using a larger patient

    Perform Achieve Trade (PAT) is a market-based incentive mechanism to promote energy efficiency. The purpose of this work is to address the challenges inherent to inconsistent representation of business processes, and interoperability issues in PAT like cap-and-trade mechanisms especially when scaled. Studies by various agencies have highlighted that as the mechanism evolves including more industrial sectors and industries in its ambit, implementation will become more challenging. This paper analyses the major needs of PAT (namely tracking, monitoring, auditing & verifying energy-saving reports, and providing technical support & guidance to stakeholders); and how the aforesaid reasons affect them. Though current technologies can handle these challenges to an extent, standardization activities for implementation have been scanty for PAT and this work attempts to evolve them. The inconsistent modification of business processes, rules, and procedures across stakeholders, and interoperability among heterogeneous systems are addressed. This paper proposes the adoption of specifically two standards into PAT, namely Business Process Model and Notation for maintaining consistency in business process modelling, and Common Information Model (IEC 61970, 61968, 62325 combined) for information exchange. Detailed architecture and organization of these adoptions are reported. The work can be used by PAT implementing agencies, stakeholders, and standardization bodies.

  10. Population-level scale-up of cervical cancer prevention services in a low-resource setting: development, implementation, and evaluation of the cervical cancer prevention program in Zambia.

    Groesbeck P Parham

    Full Text Available Very few efforts have been undertaken to scale-up low-cost approaches to cervical cancer prevention in low-resource countries.In a public sector cervical cancer prevention program in Zambia, nurses provided visual-inspection with acetic acid (VIA and cryotherapy in clinics co-housed with HIV/AIDS programs, and referred women with complex lesions for histopathologic evaluation. Low-cost technological adaptations were deployed for improving VIA detection, facilitating expert physician opinion, and ensuring quality assurance. Key process and outcome indicators were derived by analyzing electronic medical records to evaluate program expansion efforts.Between 2006-2013, screening services were expanded from 2 to 12 clinics in Lusaka, the most-populous province in Zambia, through which 102,942 women were screened. The majority (71.7% were in the target age-range of 25-49 years; 28% were HIV-positive. Out of 101,867 with evaluable data, 20,419 (20% were VIA positive, of whom 11,508 (56.4% were treated with cryotherapy, and 8,911 (43.6% were referred for histopathologic evaluation. Most women (87%, 86,301 of 98,961 evaluable received same-day services (including 5% undergoing same-visit cryotherapy and 82% screening VIA-negative. The proportion of women with cervical intraepithelial neoplasia grade 2 and worse (CIN2+ among those referred for histopathologic evaluation was 44.1% (1,735/3,938 with histopathology results. Detection rates for CIN2+ and invasive cervical cancer were 17 and 7 per 1,000 women screened, respectively. Women with HIV were more likely to screen positive, to be referred for histopathologic evaluation, and to have cervical precancer and cancer than HIV-negative women.We creatively disrupted the 'no screening' status quo prevailing in Zambia and addressed the heavy burden of cervical disease among previously unscreened women by establishing and scaling-up public-sector screening and treatment services at a population level.

  11. Fusion Implementation

    International Nuclear Information System (INIS)

    If a fusion DEMO reactor can be brought into operation during the first half of this century, fusion power production can have a significant impact on carbon dioxide production during the latter half of the century. An assessment of fusion implementation scenarios shows that the resource demands and waste production associated with these scenarios are manageable factors. If fusion is implemented during the latter half of this century it will be one element of a portfolio of (hopefully) carbon dioxide limiting sources of electrical power. It is time to assess the regional implications of fusion power implementation. An important attribute of fusion power is the wide range of possible regions of the country, or countries in the world, where power plants can be located. Unlike most renewable energy options, fusion energy will function within a local distribution system and not require costly, and difficult, long distance transmission systems. For example, the East Coast of the United States is a prime candidate for fusion power deployment by virtue of its distance from renewable energy sources. As fossil fuels become less and less available as an energy option, the transmission of energy across bodies of water will become very expensive. On a global scale, fusion power will be particularly attractive for regions separated from sources of renewable energy by oceans

  12. Solutions for cost effective assessment of software based instrumentation and control systems in nuclear power plants. Report prepared within the framework of the Technical Working Group on Nuclear Power Plant Control and Implementation

    International Nuclear Information System (INIS)

    The introduction of software based instrumentation and control (I and C) systems for use in nuclear power plants, mainly due to I and C modernization activities, has raised many issues of safety and economics. Many of these issues have been raised in the IAEA Technical Working Group on Nuclear Power Plant Control and Instrumentation (TWG-NPPCI) meetings and by other organizations, such as the OECD and the European Commission. One increasingly important issue is the need for engineering solutions to justify them for the cost effective assessment and deployment of software based I and C systems. To address this important issue, the IAEA put together the Co-ordinated Research Project (CRP) on Solutions for Cost Effective Assessments of Software based I and C Systems. The overall objective of the project is to facilitate the cost effective assessment of software based I and C systems in nuclear power plants. This is necessary to address obsolescence issues, to introduce new beneficial functionality, and to improve overall performance. The engineering solutions developed in this CRP will contribute to this overall objective. The objective of the CRP was reached through co-ordinated research and collected experience in the areas of project management; requirements specifications; use of software explicitly designed for nuclear applications, use of commercial off the shelf (COTS) products, generic pre-qualification of systems and components; safety and reliability enhancements; verification and validation; and licensing impact. This TECDOC is the result of the research and collected experience put together under this CRP. The CRP participants gave presentations on their work performed as part of this CRP at the various meetings of the group. The first meeting of the CRP was held in Vienna on 8-12 November 1999 in which the participants developed the objectives, scope, and outline of this report. The second meeting was held in Halden, Norway on 4-8 December 2000 and the

    This chapter describes several aspects of MR-HIFU treatment for breast cancer. The current and future applications, technical developments and clinical results are discussed. MR-HIFU ablation is under investigation for the treatment of breast cancer, but is not yet ready for clinical implementation. Firstly, the efficacy of MR-HIFU ablation should be investigated in large trials. The existing literature shows that results of initial, small studies are moderate, but opportunities for improvement are available. Careful patient selection, taking treatment margins into account and using a dedicated breast system might improve treatment outcomes. MRI-guidance has proven to be beneficial for the accuracy and safety of HIFU treatments because of its usefulness before, during and after treatments. In conclusion, MR-HIFU is promising for the treatment of breast cancer and might lead to a change in breast cancer care in the future. PMID:26486332

  14. Planning for environmental restoration of radioactively contaminated sites in central and eastern Europe. V. 3: Technologies for, and the implementation of, environmental restoration of contaminated sites. Proceedings of a workshop held within the technical co-operation project

    International Nuclear Information System (INIS)

    The radioactive contaminant materials resulting from diverse activities in relation to the nuclear fuel cycle, defence related operations, and various industries in addition to medical and research facilities represent perhaps the most severe and immense pollution left from a past era. The political changes in central and eastern Europe (CEE) not only brought some disclosure of the radioactively contaminated sites, but also resulted in a political condition in which this region became receptive to co-operation from a range of outside countries. The subjects of the first workshop held in Budapest, 4-8 October 1993, was the identification and characterization of radioactively contaminated sites in the region. The second part of the project and the second workshop (Piestany, Slovak Republic, 12-16 April 1994) involved planning and preparing the identified sites for restoration. This included items such as the restoration objectives, dose and environmental assessment, cost analysis, strategy and prioritization. Eventually, the third part of the project covered technologies for, and the implementation of, environmental restoration. The third and final workshop was held in Rez, Czech Republic, 12-16 December 1994. Refs, figs, tabs

    Westslope cutthroat trout (Oncorhynchus clarki lewisi) and bull trout (Salvelinus confluentus) are currently of special concern regionally and are important to the culture and subsistence needs of the Coeur d'Alene Tribe. The mission of the Coeur d'Alene Tribe Fisheries Program is to restore and maintain these native trout and the habitats that sustain them in order to provide subsistence harvest and recreational fishing opportunities for the Reservation community. The adfluvial life history strategy exhibited by westslope cutthroat and bull trout in the Lake Coeur d'Alene subbasin makes these fish susceptible to habitat degradation and competition in both lake and stream environments. Degraded habitat in Lake Coeur d'Alene and its associated streams and the introduction of exotic species has lead to the decline of westslope cutthroat and listing of bull trout under the endangered species act (Peters et al. 1998). Despite the effects of habitat degradation, several streams on the Reservation still maintain populations of westslope cutthroat trout, albeit in a suppressed condition (Table 1). The results of several early studies looking at fish population status and habitat condition on the Reservation (Graves et al. 1990; Lillengreen et al. 1993, 1996) lead the Tribe to aggressively pursue funding for habitat restoration under the Northwest Power Planning Council's (NWPPC) resident fish substitution program. Through these efforts, habitat restoration needs were identified and projects were initiated. The Coeur d'Alene Tribe Fisheries Program is currently involved in implementing stream habitat restoration projects, reducing the transport of sediment from upland sources, and monitoring fish populations in four watersheds on the Coeur d'Alene Reservation (Figure 1). Restoration projects have included riparian plantings, addition of large woody debris to streams, and complete channel reconstruction to restore historical natural

    Full Text Available Low fruit and vegetable (FV intake is a leading risk factor for chronic disease globally as well as in the United States. Much of the population does not consume the recommended servings of FV daily. This paper describes the development of psychosocial measures of FV intake for inclusion in the U.S. National Cancer Institute's 2007 Food Attitudes and Behaviors Survey.This was a cross-sectional study among 3,397 adults from the United States. Scales included conventional constructs shown to be correlated with fruit and vegetable intake (FVI in prior studies (e.g., self-efficacy, social support, and novel constructs that have been measured in few- to- no studies (e.g., views on vegetarianism, neophobia. FVI was assessed with an eight-item screener. Exploratory factor analysis, Cronbach's alpha, and regression analyses were conducted.Psychosocial scales with Cronbach's alpha ≥0.68 were self-efficacy, social support, perceived barriers and benefits of eating FVs, views on vegetarianism, autonomous and controlled motivation, and preference for FVs. Conventional scales that were associated (p<0.05 with FVI were self-efficacy, social support, and perceived barriers to eating FVs. Novel scales that were associated (p<0.05 with FVI were autonomous motivation, and preference for vegetables. Other single items that were associated (p<0.05 with FVI included knowledge of FV recommendations, FVI "while growing up", and daily water consumption.These findings may inform future behavioral interventions as well as further exploration of other potential factors to promote and support FVI.

    Software Defined Radio makes wireless communications easier, more efficient, and more reliable. This book bridges the gap between academic research and practical implementation. When beginning a project, practicing engineers, technical managers, and graduate students can save countless hours by considering the concepts presented in these pages. The author covers the myriad options and trade-offs available when selecting an appropriate hardware architecture. As demonstrated here, the choice between hardware- and software-centric architecture can mean the difference between meeting an aggressive schedule and bogging down in endless design iterations. Because of the author’s experience overseeing dozens of failed and successful developments, he is able to present many real-life examples. Some of the key concepts covered are: Choosing the right architecture for the market – laboratory, military, or commercial Hardware platforms – FPGAs, GPPs, specialized and hybrid devices Standardization efforts to ens...

    Multi-parametric Magnetic Resonance Imaging, and specifically Dynamic Contrast Enhanced (DCE) MRI, play increasingly important roles in detection and staging of prostate cancer (PCa). One of the actively investigated approaches to DCE MRI analysis involves pharmacokinetic (PK) modeling to extract quantitative parameters that may be related to microvascular properties of the tissue. It is well-known that the prescribed arterial blood plasma concentration (or Arterial Input Function, AIF) input can have significant effects on the parameters estimated by PK modeling. The purpose of our study was to investigate such effects in DCE MRI data acquired in a typical clinical PCa setting. First, we investigated how the choice of a semi-automated or fully automated image-based individualized AIF (iAIF) estimation method affects the PK parameter values; and second, we examined the use of method-specific averaged AIF (cohort-based, or cAIF) as a means to attenuate the differences between the two AIF estimation methods. Two methods for automated image-based estimation of individualized (patient-specific) AIFs, one of which was previously validated for brain and the other for breast MRI, were compared. cAIFs were constructed by averaging the iAIF curves over the individual patients for each of the two methods. Pharmacokinetic analysis using the Generalized kinetic model and each of the four AIF choices (iAIF and cAIF for each of the two image-based AIF estimation approaches) was applied to derive the volume transfer rate (K(trans)) and extravascular extracellular volume fraction (ve) in the areas of prostate tumor. Differences between the parameters obtained using iAIF and cAIF for a given method (intra-method comparison) as well as inter-method differences were quantified. The study utilized DCE MRI data collected in 17 patients with histologically confirmed PCa. Comparison at the level of the tumor region of interest (ROI) showed that the two automated methods resulted in

    , including the Coeur d'Alene Indian Reservation (Coeur d'Alene Tribe 1998). Implicit in this statement is a commitment to provide native subsistence resources in the present and near future as well as the long-term by employing all the mitigation and conservation measures available to them. The development of this Habitat Protection Plan is intended to provide additional planning level guidance as the implementation of conservation measures moves forward. The purpose of this plan is to develop a systematic approach to habitat restoration that will ultimately lead to self-perpetuating, harvestable populations of native fish, wildlife and botanical species. Specifically, it is our intention to apply the principles and analyses presented in this plan to prioritize future restoration efforts that receive funding under the Northwest Power Planning Council's Resident Fish and Wildlife Mitigation Programs. Using an ecosystem restoration approach based on landscape ecology concepts (Primack 1993), the basic premise of the plan is to (1) protect functioning habitat conditions and (2) restore degraded habitat conditions. This plan focuses on habitat conditions at the watershed scale (macrohabitat) rather than on the needs of single species and/or species guilds. By focusing restoration efforts at a macrohabitat level, restoration efforts target all native species inhabiting that area. This approach marks a paradigm shift that emphasizes ecological based restoration rather than species-specific restoration. Traditionally, fish managers and wildlife managers have approached restoration independently, often dedicating resources to a single species by focusing on specific habitat types on a small spatial scale (microhabitat) (Robinson and Bolen 1989, Marcot et al. 2002). This management technique has done little to curb declines despite large budgets (Pianka 1994). Restoration on a landscape level has shown promising results (Holling 1992) and many riparian and wetland

    Systematic and effective control of age-related degradation of safety-related components, systems, and structures in nuclear power plants (NPPs) is an important challenge to plant operators. Several data bases, available to provide guidance on aging management, are summarized. However, the ultimate consideration is: How effectively is aging management being implemented at individual plants? Illustrated here is a specific strategy that served to develop the technical data base for the Nuclear Plant Aging Research Program. The strategy is comprehensive, systematic, and adaptable. Effective aging management at NPPs could be facilitated by a parallel strategy. The elements of a strategy are suggested

    OAK B202 Final Technical Report. The present generation of reactor analysis methods uses few-group nodal diffusion approximations to calculate full-core eigenvalues and power distributions. The cross sections, diffusion coefficients, and discontinuity factors (collectively called ''group constants'') in the nodal diffusion equations are parameterized as functions of many variables, ranging from the obvious (temperature, boron concentration, etc.) to the more obscure (spectral index, moderator temperature history, etc.). These group constants, and their variations as functions of the many variables, are calculated by assembly-level transport codes. The current methodology has two main weaknesses that this project addressed. The first weakness is the diffusion approximation in the full-core calculation; this can be significantly inaccurate at interfaces between different assemblies. This project used the nodal diffusion framework to implement nodal quasidiffusion equations, which can capture transport effects to an arbitrary degree of accuracy. The second weakness is in the parameterization of the group constants; current models do not always perform well, especially at interfaces between unlike assemblies. The project developed a theoretical foundation for parameterization and homogenization models and used that theory to devise improved models. The new models were extended to tabulate information that the nodal quasidiffusion equations can use to capture transport effects in full-core calculations.

Technical rules may also achieve importance in law due to a legal transformation standard. Here, rigid and flexible reference are controversial with regard to their admissibility from the point of view of constitutional law. In case of a divergence from the generally accepted technical rules, it is assumed - refutably - that the necessary care had not been taken. Technical rules are one out of several sources of information; they have no normative effect. This may result in a duty of anyone applying them to review the state of technology himself. (orig.)

  1. Application of intensity modulated radiation therapy for the cancer patients treatment in Bach Mai Hospital

    International Nuclear Information System (INIS)

    Intensity modulated radiotherapy (IMRT) is one of the modern techniques in cancer treatment, in which dose is delivered optimally into the shape of the tumor and minimally in surround benign tissues. In developed countries, this technique has been performed routinely by Linacs with MLC for tumors at the critical areas. In Vietnam, because of the wet climate, the use of Linacs with MLC is difficult to operate and maintain. However, IMRT can be implemented by Linacs without MLC via independent jaws, Jaws-only IMRT (JO-IMRT), in which beams are separated into many segments with different weights to optimize highest dose in the tumor and lowest dose in the surrounding health organs. Methods: We describe the new treatment technic application and compare it with normal radiotherapy method (3D-CRT). Results: From 7/2008, the Dep of Nuclear Medicine and Oncology at Bach Mai Hospital has been conducting JO-IMRT to treat cancer patients. Up to now, we have 81 cases treated by IMRT including head and neck cancers (NPC, larynx cancer, maxillary sinus cancer, brain tumor), cancers in the thorax (esophagus cancer, lung cancer, breast cancer), cancers in the pelvis (prostate cancer, cervical cancer, rectal cancer). On the average, beam number is from 5 to 9 and 5-9 segments per beam. Treatment time for a fraction is from 6 to 12 minutes with 2.25 Gy for CTV1 per day. Discrepancies of doses were below 3% (0.15 to 2.84%) between planning and practice. In plan, the preeminences with IMRT are clearly superior to 3D radiation therapy. In clinical, almost patients had good respond, whereas side effects were quite less than conventional radiotherapy. Conclusions: JO-IMRT is a modern technic with more advantage than normal 3D-CRT. It help radiation dose to concentrate maximally in treatment target while influence minimally for sensitive surrounding tissues. Another, it is a high technic to appropriate with the climatic condition in Vietnam. (author)

    Combined kV-MV cone-beam CT (CBCT) is a promising approach to accelerate imaging for patients with lung tumors treated with deep inspiration breath-hold. During a single breath-hold (15 s), a 3D kV-MV CBCT can be acquired, thus minimizing motion artifacts and increasing patient comfort. Prior to clinical implementation, positioning accuracy was evaluated and compared to clinically established imaging techniques. An inhomogeneous thorax phantom with four tumor-mimicking inlays was imaged in 10 predefined positions and registered to a planning CT. Novel kV-MV CBCT imaging (90 arc) was compared to clinically established kV-chest CBCT (360 ) as well as nonclinical kV-CBCT and low-dose MV-CBCT (each 180 ). Manual registration, automatic registration provided by the manufacturer and an additional in-house developed manufacturer-independent framework based on the MATLAB registration toolkit were applied. Systematic setup error was reduced to 0.05 mm by high-precision phantom positioning with optical tracking. Stochastic mean displacement errors were 0.5 ± 0.3 mm in right-left, 0.4 ± 0.4 mm in anteroposterior and 0.0 ± 0.4 mm in craniocaudal directions for kV-MV CBCT with manual registration (maximum errors of no more than 1.4 mm). Clinical kV-chest CBCT resulted in mean errors of 0.2 mm (other modalities: 0.4-0.8 mm). Similar results were achieved with both automatic registration methods. The comparison study of repositioning accuracy between novel kV-MV CBCT and clinically established volume imaging demonstrated that registration accuracy is maintained below 1 mm. Since imaging time is reduced to one breath-hold, kV-MV CBCT is ideal for image guidance, e.g., in lung stereotactic ablative radiotherapy. (orig.)

  8. LSST operation simulator implementation

    Science.gov (United States)

    Delgado, Francisco; Cook, Kem; Miller, Michelle; Allsman, Robyn; Pierfederici, Francesco

    2006-06-01

    We have developed an operation simulator for the Large Synoptic Survey Telescope (LSST) that is an implementation in Python language using the SimPy extension, with a modular and object-oriented design. The main components include a telescope model, a sky model, a weather database for 3 sites, a scheduler and multiple observing proposals. All the proposals derive from a parent class which is fully configurable through about 75 parameters to implement a specific science survey. These parameters control the target selection region, the composition of the sequence of observations for each field, the timing restrictions and filter selection criteria of each observation, the lunation handling, seeing limits, etc. The current implemented proposals include Weak Lensing, Near Earth Asteroids, Supernova and Kuiper Belt Objects. The telescope model computes the slew time delay from the current position to any given target position, using a complete kinematic model for the mount, dome and rotator, as well as optics alignment corrections. The model is fully configurable through about 50 parameters. The scheduler module combines the information received from the proposals and the telescope model for selecting the best target at each moment, promoting targets that fulfill multiple surveys and storing all the simulator activities in a MySQL database for further analysis of the run. This scheduler is also configurable; for example, balancing the weight of the slew time delay in selecting the next field to observe. This simulator has been very useful in clarifying some of the technical and scientific capabilities of the LSST design, and gives a good baseline for a future observation scheduler.

    The volume of stranded natural gas global reserves is substantial and represents more than a third of the world's proven natural gas reserves. In Brazil, recent discoveries operated by PETROBRAS, with participation of other companies, show trend of stranded gas reserves incorporation, associated gas or not. This dissertation's main objective is to make a technical and economic analysis of the implementation of small-scale GTL technology for the exploitation of stranded associated natural gas offshore in Brazil. Thus, the dissertation held, initially, a survey of the processes of gasification and the manufacturers with technologies and projects based on these processes, for specific offshore applications. In a second stage, the conditions of the offshore environment were examined. After the confrontation of the technologies available and the operation conditions, a technological alternative has been chosen to be used in an illustrative economic analysis. The results show that GTL offshore option becomes viable at a minimum price of about US $ 40.00 / barrel. Although this value is greater than the robustness price adopted by PETROBRAS, there are prospects for the reduction of GTL technology costs. (author)

  12. Innovative technical plasma applications

    International Nuclear Information System (INIS)

    Plasma is the predominant status of matter, in stars as well as in interstellar space. In science, it was only recognized rather late as a specific (fourth) state of matter: Sir William Crookes described it in 1879 as “radiant matter”, Irving Langmuir created the name “plasma” in 1928. Technically generated plasma is employed very broadly in modern technology. Some examples are Plasma Displays, Fluorescent Lamps (also the modern Energy Saving Lamps), Corona Discharges (for e.g. Ozone generation, or even engine ignition), arc welding and cutting, reactive ion etching, mass spectroscopy, ion rocket engines and many more. Very early since the development of the laser, it was also employed to generate a plasma (spark) in air or on surfaces. Generally, for this purpose at least ns (“Giant”) pulses have to be used. In more recent times, pico- and femtosecond pulses have allowed to create plasma very easily and effectively. Laser fusion may represent the ultimate application in this direction, based on highly amplified ns pulses for inertial confinement or ps pulses designed as fast igniter. The idea of employing laser pulses for the ignition of engines was attempted for the first time in 1978, although with inadequate tools like the CO2 laser. After a long time of inactivity in this field, about 10 years ago a few institutions like Vienna University of Technology first resumed this approach with the help of modern type solid-state lasers and started systematic investigations around the idea of laser ignition of internal combustion engines. Now, this technique has reached a high degree of maturity; remaining problems lie on the development level and are to be solved soon. Ambitious product development by leading engine producers or ignition equipment suppliers has been started world-wide since several years and, as a result, in one or two years laser ignition will probably be imple-mented into high power gas engines or, somewhat later, high-priced automotive

    2015-08-01

    While initial implementations of prostate MRI suffered from suboptimal performance in tumor detection, technological advances over the past decade have allowed modern multi-parametric prostate MRI (mpMRI) to achieve high diagnostic accuracy for detection, localization, and staging and thereby impact patient management. A particular emerging application of mpMRI is in the pre-biopsy setting to allow for MRI-targeted biopsy, for instance, through real-time MRI/ultrasound fusion, which may help reduce the over-detection of low-risk disease and selectively detect clinically significant cancers, in comparison with use of standard systematic biopsy alone. mpMRI and MRI-targeted biopsy are spreading beyond the large academic centers to increasingly be adopted within small and community practices. Aims of this review article are to summarize the hardware and sequences used for performing mpMRI, explore patient specific technical considerations, delineate approaches for study interpretation and reporting [including the recent American College of Radiology Prostate Imaging Reporting and Data System (PI-RADS) version 2], and describe challenges and implications relating to the widespread clinical implementation of mpMRI.

  1. Accelerated repopulation as a cause of radiation treatment failure in non-small cell lung cancer: review of current data and future clinical strategies.

    Science.gov (United States)

    Yom, Sue S

    2015-04-01

    Despite convincing evidence that the principles of accelerated repopulation would open up additional therapeutic opportunities in the treatment of advanced-stage non-small cell lung cancer, this strategy has been generally underexplored. The implementation of accelerated radiotherapy schedules has been hampered by logistical barriers, concerns about acute toxicity, and the prioritization of integrating concurrent chemotherapy into the standard treatment platform. At present, it is unclear to what extent accelerated fractionation will influence future treatment paradigms in non-small cell lung cancer, although technical advances in radiotherapy, allowing higher dose delivery with reduced toxicity, could permit the development of more convenient and tolerable forms of accelerated schedules.

  8. Implementation of Quality Control Protocol in Mammography: A Serbian Experience

    International Nuclear Information System (INIS)

    Mammography is method of choice for early detection of breast cancer. In Serbia, mammography is performed only clinically, although there is a long term plan to introduce mammography as screening method. Currently there are 60 mammography units in practice in Serbia, resulting with 70 000 mammographies annually. The purpose of this paper is preliminary evaluation of the mammography practice in Serbia, having in mind the annual number of examinations and fact that part of examination is performed on women without any clinical signs. For pilot implementation of Quality Control (QC) protocol in mammography, five hospitals with highest workload have been selected, representing the typical mammography practice in Serbia. Developed QC protocol, based on European guidelines for quality assurance in breast cancer screening and diagnosis, actual practice and resources, includes equipment testing and maintenance, staff training and QC management and allocation of responsibilities. Subsequently, it should be applied on the national scale. The survey demonstrated considerable variations in technical parameters that affect image quality and patients doses. Mean glandular doses ranged from 0.12 to 2.8 mGy, while reference optical density ranged from 1.2 to 2.8. Main problems were associated with film processing, viewing conditions and optical density control. The preliminary survey of mammography practice highlighted the need for optimization of radiation protection and training of operating staff, although the survey itself was very valuable learning process for all participants. Furthermore, systematic implementation of QC protocol should provide reliable performance of mammography units and maintain satisfactory image quality and keep patient doses as low as reasonably practical.(author)

  13. External Technical Reviews in the Environmental Management Program

    International Nuclear Information System (INIS)

    The Environmental Management (EM) program believes strongly in reducing the technical risk of its projects and has initiated External Technical Reviews (ETR) as one of several steps to ensure the timely resolution of engineering and technology issues. EM's Office of Engineering and Technology is leading the ETR process and is working closely with Federal Project Directors to review such issues as technology development, systems integration, design, operations, maintenance, and nuclear safety. EM has completed several successful reviews using expert engineers and scientists from private industry and academia over the last two years. Additional external technical reviews will be conducted to support key project decisions and will be a mainstay of the EM program. The purpose of an ETR is to reduce technical risk and uncertainty. These independent reviews provide pertinent information for EM to assess technical risk associated with projects and develop strategies for reducing the technical risk, and provide technical information needed to support critical project decisions. Technical risk reduction increases the probability of successful implementation of technical scope. In general, an ETR assesses technical bases, technology development, and technical risk identification and handling strategies. The three key objectives of every ETR are: - To determine if the technology, process, system, or design under review will meet project objectives and requirements, - To identify any issues (show-stoppers) preventing successful implementation of the technology, process, system, or design under review, and - To identify issues or data needed to support critical or other project or program decisions. The specific objectives of ETRs may vary, but generally include: - Determining if technical objectives are well known and defined; - Determining if alternatives have been identified and effectively evaluated; - Determining if technology development is well planned and executed

    Optimizing the treatment of breast cancer remains a major topic of interest. In current clinical practice, breast-conserving therapy is the standard of care for patients with localized breast cancer. Technological developments have fueled interest in less invasive breast cancer treatment. Magnetic resonance-guided high-intensity focused ultrasound (MR-HIFU) is a completely noninvasive ablation technique. Focused beams of ultrasound are used for ablation of the target lesion without disrupting the skin and subcutaneous tissues in the beam path. MRI is an excellent imaging method for tumor targeting, treatment monitoring, and evaluation of treatment results. The combination of HIFU and MR imaging offers an opportunity for image-guided ablation of breast cancer. Previous studies of MR-HIFU in breast cancer patients reported a limited efficacy, which hampered the clinical translation of this technique. These prior studies were performed without an MR-HIFU system specifically developed for breast cancer treatment. In this article, a novel and dedicated MR-HIFU breast platform is presented. This system has been designed for safe and effective MR-HIFU ablation of breast cancer. Furthermore, both clinical and technical challenges are discussed, which have to be solved before MR-HIFU ablation of breast cancer can be implemented in routine clinical practice.

    TRUPACT-1, the TRansUranic PACkage Transporter is a packaging designed to transport defense contact handled transuranic (CH-TRU) waste from generating and interim TRU waste storage facilities to the Waste Isolation Pilot Plant (WIPP). Prior to fabrication and procurement of a full fleet, an initial design (TRUPACT-1) will be introduced to the defense TRU waste complex through use in an operational prototype fleet which will consist of Units 1, 2, and 3. In an effort to provide a relatively smooth introduction of the TRUPACT-1, the TRUPACT Technical Team (TTT) has developed the following implementation plan. The plan provides detailed information on user handling opportunities, schedules, equipment, responsibilities, reporting and data collection activities to be performed. The intent of this document is to provide users of the TRUPACT-1 with a guidance document, complete with references, that will allow the smooth introduction of this new transportation system by providing the information necessary for collecting operational, performance and cost data. These data will be used in modeling and full fleet design and procurement activities. In addition, these data will help fine tune procedures in the inspection and maintenance document and the operational document. Additional objectives of this plan are to aid in the establishment of site operational, inspection and maintenance procedures as well as training of site operators and briefing state and local officials.

    Numerous Building Information Modelling (BIM) tools are well established and potentially beneficial in certain uses. However, issues of adoption and implementation persist, particularly for on-site use of BIM tools in the construction phase. We describe an empirical case-study of the implementation...... of an innovative ‘Site BIM’ system on a major hospital construction project. The main contractor on the project developed BIM-enabled tools to allow site workers using mobile tablet personal computers to access design information and to capture work quality and progress data on-site. Accounts show...... that ‘Site BIM’, while judged to be successful and actively supporting users, was delivered through an exploratory and emergent development process of informal prototyping. Technical IT skills were adopted into the construction project through personal relationships and arrangements rather than formal...

    2014-01-01

    Background: Software systems accumulate technical debt (TD) when short-term goals in software development are traded for long term goals (e.g., quick-and-dirty implementation to reach a release date vs. a well-refactored implementation that supports the long term health of the project). Some forms of TD accumulate over time in the form of source code that is difficult to work with and exhibits a variety of anomalies. A number of source code analysis techniques and tools have been proposed to ...

  6. TECHNICAL IMPEDIMENTS TO SOFTWARE REUSE

    B.JALENDER,

    2010-11-01

    Full Text Available A good software reuse process facilitates the increase of productivity, quality, reliability, and the decrease of costs and implementation time. One of major impediments to realizing software reusability in many organizations is the inability to locate and retrieve existing software components. An initial investment is required to start a software reuse process, but that investment pays for itself in a few reuses. In short, the development of a reuse process and repository produces a base of knowledge that improves in quality after every reuse, minimizing the amount of development work required for future projects and ultimately reducing the risk of new projects that are based on repository knowledge. This paper addresses the technical impediments to software component reuse technology.

  8. Technical and dosimetric aspects of quality control in mammography

    International Nuclear Information System (INIS)

    Mammography is an effective method for early detection of breast cancer. Before screening programmes using mammography are implemented, a risk (financial cost)/benefit analysis has to be made and a quality-control programme for the technical and dosimetric aspects has to be adopted. This should include daily checks on the film processing and the total mammography procedure. The installation of a mAs meter is essential for daily checks and can be used for determination of the absorbed dose. Accurate determination of the tube voltage is essential with regard to absorbed dose variations. The focal spot size should be measured rather than relying on the value specified by the manufacturer. The determination of the focal charge (mAs) value for actual radiographs of female breasts combined with a measurement of the compressed breast thickness provides information on the absorbed dose values for actual radiographs. An approximately 50 mm thick poly(methyl methacrylate) phantom can be used for determination of absorbed dose in mammography. (author)

    The National Aeronautics and Space Act of 1958 established NASA and charged it to "provide for the widest practicable and appropriate dissemination of information concerning its activities and the results thereof." The search for innovative methods to distribute NASA's information lead a grass-roots team to create the NASA Technical Report Server (NTRS), which uses the World Wide Web and other popular Internet-based information systems as search engines. The NTRS is an inter-center effort which provides uniform access to various distributed publication servers residing on the Internet. Users have immediate desktop access to technical publications from NASA centers and institutes. The NTRS is comprised of several units, some constructed especially for inclusion in NTRS, and others that are existing NASA publication services that NTRS reuses. This paper presents the NTRS architecture, usage metrics, and the lessons learned while implementing and maintaining the service. The NTRS is largely constructed with freely available software running on existing hardware. NTRS builds upon existing hardware and software, and the resulting additional exposure for the body of literature contained ensures that NASA's institutional knowledge base will continue to receive the widest practicable and appropriate dissemination.

  10. The role of cancer registries in cancer control.

    Science.gov (United States)

    Parkin, Donald Maxwell

    2008-04-01

    Cancer control aims to reduce the incidence, morbidity, and mortality of cancer and to improve the quality of life of cancer patients through the systematic implementation of evidence-based interventions in prevention, early diagnosis, treatment, and palliative care. In the context of a national cancer control program (NCCP), a cancer surveillance program (CSP), built around a population-based cancer registry, is an essential element. Data on the size and evolution of the cancer burden in the population are essential to evaluation of the current situation, to setting objectives for cancer control, and defining priorities. Cancer data are essential in monitoring the progress of the implementation of an NCCP, as well as providing an evaluation of the many individual cancer control activities. In the context of an NCCP, the CSP should provide a focus of epidemiological expertise, not only for providing statistical data on incidence, mortality, stage distribution, treatment patterns, and survival but also for conducting studies into the important causes of cancer in the local situation, and for providing information about the prevalence of exposure to these factors in the population. Cancer surveillance via the population-based registry therefore plays a crucial role in formulating cancer control plans, as well as in monitoring their success. PMID:18463952

  12. OSH technical reference manual

    Energy Technology Data Exchange (ETDEWEB)

    1993-11-01

    In an evaluation of the Department of Energy (DOE) Occupational Safety and Health programs for government-owned contractor-operated (GOCO) activities, the Department of Labor`s Occupational Safety and Health Administration (OSHA) recommended a technical information exchange program. The intent was to share written safety and health programs, plans, training manuals, and materials within the entire DOE community. The OSH Technical Reference (OTR) helps support the secretary`s response to the OSHA finding by providing a one-stop resource and referral for technical information that relates to safe operations and practice. It also serves as a technical information exchange tool to reference DOE-wide materials pertinent to specific safety topics and, with some modification, as a training aid. The OTR bridges the gap between general safety documents and very specific requirements documents. It is tailored to the DOE community and incorporates DOE field experience.

    Full Text Available Introduction: fast track pathways for diagnosis of cancer intend to decrease delays in diagnosis and treatment of cancer. It is recommended to initiate treatment in a period no longer than 30 days since admission in these circuits. Aims: to know the characteristics and fluency of our Fast Track Diagnostic Pathway (FTDP for Colorectal Cancer (CRC, with special attention to those patients selected for surgical treatment as a first choice. Material and method: all patients who entered the FTDP for CRC during a period of 2 years (2008-2009 were analyzed as well as the rest of patients also diagnosed with CRC but never seen in the FTDP. Results: of the 316 patients referred to the FTDP only 78 (24.7% were diagnosed as having some kind of cancer derived from the digestive system. At the end 61 patients (19.3% were diagnosed with CCR. The time interval from entry into the FTDP to the first hospital visit was 3 days (range 1-8, and the interval until colonoscopy was performed was 11.5 days (range 1-41. 14 (41.1% of those patients chosen for surgery were operated on in a period lesser than 30 days while 28 patients (82.3% underwent surgery before day 45 since admission into the circuit. Conclusions: though the functioning of the FTDP is acceptable, any increase in number of patients can generate delays. For this reason it is advisable to have a team to assure a good functioning of the FTDP. A proper follow-up of the whole process will possibly avoid unnecessary delays and it will improve coordination of the different phases of the fast track pathway and treatment. As the diagnostic outcome is poor it is mandatory to implement alternatives programs like screening of asymptomatic population, allowing an early detection of this condition.Introducción: los circuitos de diagnóstico rápido de cáncer (CDRC pretenden disminuir las demoras en el diagnóstico y tratamiento del cáncer colorrectal (CCR.

  2. IMPLEMENTATION AND APPLICATION OF EUROCODES

    Directory of Open Access Journals (Sweden)

    Holický Milan

    2012-10-01

    Full Text Available Technical and editorial problems may be encountered during the implementation of Eurocodes into the systems of national standards. The main technical problems to be solved include specification of the target reliability levels of different types of construction works, definition of characteristic values, partial and combination factors and load combination rules for structures and geotechnical design. It is expected that in the next generation of Eurocodes further harmonisation and reduction of NDPs on the basis of technical assessment will be provided. Present generation of Eurocodes encompass a suite of 58 Parts which represents a great achievement in European harmonization of structural codes. The key role in the design of new and existing structures represents the concept of reliability differentiation of construction works and the selection of target reliability level. Recommended target reliability level, expressed commonly by reliability index b = −Φ-1(p, where Φ denotes the standardized normal distribution function and p the failure probability, are provided in several documents. Load combination rules for verification of geotechnical design (ULS of type GEO give three alternative approaches leading in some cases to considerably different results. For example, resulting dimensions of common footing may have differences about 20 to 40 %. Other technical problems of implementation include lack of guidance for application of different design situations. For example a structure under fire should be verified according to the accidental design situation for which alternative combination factors are indicated in EN 1990. During subsequent repair the structure should comply with the requirements for the transient design situation, for which, up to now, there are no explicit rules for existing structures provided by Eurocodes. Another problem is a unified definition of the characteristic values for variable actions, particularly for imposed

Thematic plans were prepared for food irradiation, river basin management and the role of isotopic techniques in the control of communicable diseases. The Agency increased its involvement in international efforts to promote development through intensified consultation and collaboration with the United Nations system, multilateral banks, regional organizations and other relevant bodies. As part of its activities to develop strategic partnerships, the Agency signed Memoranda of Understanding with the Common Fund for Commodities, the Transplant Procurement Management Project (University of Barcelona), the National Atomic Energy Agency of Argentina and the University of Buenos Aires. A new form of partnership was entered with the Nuclear Threat Initiative to support the decommissioning of a research reactor in Serbia and Montenegro. In addition, contacts were strengthened between the Agency and regional development organizations to ensure that policies for development programmes complement each other. During 2002, achievements were made in many areas of implementation of the technical co-operation programme. Training events, expert missions and equipment procurement supported national and regional efforts to initiate or improve cancer therapy facilities. Different government nutrition supplementation programmes benefited from Agency expertise to verify they had the impact expected. In the area of water resource management, an ongoing regional project brought together more than 30 water institutes to solve water shortage problems. And in several regions, plans to construct mass- rearing facilities for medfly and tsetse were a testament that national and regional authorities are committed to the sterile insect technique for the control of insect pests.

  11. Quality and Profitability improvement by Technical Audit

    Directory of Open Access Journals (Sweden)

    Prof. Srivastava S. B.

    2009-10-01

    Full Text Available This paper is aimed for finding the Quality and Profitability Improvement by Technical Audit, through a case study and further establishing the relationship between the product quality, profitability and technical audit. Quality audit generates the report of non conformance which basically represents the deviation from committed quality of products, or in short, it may be called as postmortem of product quality. By virtue of quality audit, the commitment, implementation and follow up for product quality are aligned. This delivers a good quality of product to the customers and thus the customer is benefited. In industries, Quality Inspectors are giving their decision for quality of product in two categories, "ACCEPTED" or "REJECTED". The accepted products are coming to the customers and the rejected products become the burden / problem to the manufacturers.If accepted product quantity is within the “NORMS”, no one cares regarding the rejected product quantities, what so ever. When the rejected product quantity increases beyond the “NORMS”, the analysis process starts to find out the reasons of rejections. Sometimes, it becomes too late to search out the reasons of rejections and survival of the industry becomes a problem. By technical audit and audit report implementation such type of conditions can be avoided and controlled.Basically, Quality is the function of Man, Machine, Materials, Methods, Movement, Manufacturing Processes, Monitoring and Management (8 M’s. If the technicality of 8 M’s is corrected by Technical Audit, the product quality will improve automatically and the profitability of the organization will improve. In short it can be solicited that if 8 M’s are all right, the product quality and profitability will automatically be set right. This may become an important aspect in the scenario of Indian Industries. The findings are supported by a case study of a Process Plant (Slag Dryer of a reputed Indian Industry.

  12. Global challenges of implementing human papillomavirus vaccines

    Directory of Open Access Journals (Sweden)

    Mishra Amrita

    2011-06-01

    Full Text Available Abstract Human Papillomavirus vaccines are widely hailed as a sweeping pharmaceutical innovation for the universal benefit of all women. The implementation of the vaccines, however, is far from universal or equitable. Socio-economically marginalized women in emerging and developing, and many advanced economies alike, suffer a disproportionately large burden of cervical cancer. Despite the marketing of Human Papillomavirus vaccines as the solution to cervical cancer, the market authorization (licensing of the vaccines has not translated into universal equitable access. Vaccine implementation for vulnerable girls and women faces multiple barriers that include high vaccine costs, inadequate delivery infrastructure, and lack of community engagement to generate awareness about cervical cancer and early screening tools. For Human Papillomavirus vaccines to work as a public health solution, the quality-assured delivery of cheaper vaccines must be integrated with strengthened capacity for community-based health education and screening.

  11. 1994 DOE Technical Standards Program Workshop: Proceedings

    International Nuclear Information System (INIS)

    The DOE Technical Standards Program has been structured to provide guidance and assistance for the development, adoption, and use of voluntary standards within the Department. OMB Circular A-119, ''Federal Participation in the Development and Use of Voluntary Standards'' establishes the policy to be followed in working with voluntary standards bodies, and in adopting and using voluntary standards whenever feasible. The DOE Technical Standards Program is consistent with this policy and is dedicated to the task of promoting its implementation. The theme of this year's workshop is ''Standards Initiatives in Environmental Management fostering the development and use of industry standards for safe, environmentally responsible operations.'' The objective of the workshop is to increase the participant's awareness of the standardization activities taking place nationally and internationally and the impact of these activities on their efforts, and to facilitate the exchange of experiences, processes, and tools for implementing the program. Workshop sessions will include presentations by industry and Government notables in the environment, safety, and health arena with ample opportunity for everyone to ask questions and share experiences. There will be a breakout session which will concentrate on resolution of issues arising from the implementation of the DOE Technical Standards Program and a plenary session to discuss the plans developed by the breakout groups. Many organizations provide services and products which support the development, processing, distribution, and retrieval of standards. Those organizations listed at the end of the agenda will have exhibits available for your perusal throughout the workshop. Last year's workshop was very successful in stimulating an understanding of an interest in the standards program. This year, we hope to build on that success and provide an environment for the synergism of ideas to enhance the program and advance its implementation

  13. Cancer antigen 125 and prognosis

    DEFF Research Database (Denmark)

    Høgdall, Estrid Vilma Solyom

    2008-01-01

    PURPOSE OF REVIEW: This review addresses recently reported progress in cancer antigen 125 as a prognostic marker in patients with ovarian cancer. RECENT FINDINGS: Serum cancer antigen 125 levels measured preoperatively in both early and late stage ovarian cancer may be of prognostic value. Before...... cancer antigen 125 determination may be implemented into clinical practice, cut-off levels must be evaluated and internationally defined. Studies examining serum cancer antigen 125 levels after surgery but before, during, or after treatment confirmed that changes in serum levels are of prognostic value....... Furthermore, recent studies have shown that the level of expression of cancer antigen 125 in tissue may be an independent prognostic indicator in late stage ovarian cancer. SUMMARY: Prognostic markers may potentially help to individualize treatment within subgroups of patients. In a recent study the level of...

  18. Vocationalization of Secondary Schools: Implementation Reality or Fallacy?

    Directory of Open Access Journals (Sweden)

    Leona Mandiudza

    2013-02-01

    Full Text Available The study attempted to evaluate one of the recommendations of the Nziramasanga Commission of Inquiry into Education and Training viz the vocationalisation of the Secondary Schools curriculum. The study has established that vocationalisation in most Secondary Schools is mere window dressing, as evidenced by poor to non implementation of the policy directives in most schools due to lack of infrastructure, human resources and equipment. The interviews and observations check list done showed that the implementation of vocational subjects in secondary schools is an uphill struggle. The study also revealed that the negative perception of technical subjects perpetuated from the colonial era still prevails and affects negatively the implementation of these subjects. To make matters worse on the implementation, teachers, pupils and parents still hold the idea that pupils who do technical subjects are not academically talented. Even teachers themselves have prestige in teaching academic subjects. Teachers who teach technical subjects are looked down upon just as the subjects they teach. In the end these subjects lose popularity since teachers who are able to teach them develop an inferiority complex. The study recommends a re-education of the whole nation on the value of vocational and technical subjects. Although there are policies guiding the implementation of technical and vocational subjects there is need of strict stringent policy adherence by all stakeholders.
