    Full Text Available Cancer is one of the leading causes of death throughout the world. Advancements in early and improved diagnosis could help prevent a significant number of these deaths. Raman spectroscopy is a vibrational spectroscopic technique which has received considerable attention recently with regards to applications in clinical oncology. Raman spectroscopy has the potential not only to improve diagnosis of cancer but also to advance the treatment of cancer. A number of studies have investigated Raman spectroscopy for its potential to improve diagnosis and treatment of a wide variety of cancers. In this paper the most recent advances in dispersive Raman spectroscopy, which have demonstrated promising leads to real world application for clinical oncology are reviewed. The application of Raman spectroscopy to breast, brain, skin, cervical, gastrointestinal, oral, and lung cancers is reviewed as well as a special focus on the data analysis techniques, which have been employed in the studies.

    The use of clinical pathways in oncology care is increasingly important to patients and oncology providers as a tool for enhancing both quality and value. However, with increasing adoption of pathways into oncology practice, concerns have been raised by ASCO members and other stakeholders. These include the process being used for pathway development, the administrative burdens on oncology practices of reporting on pathway adherence, and understanding the true impact of pathway use on patient health outcomes. To address these concerns, ASCO's Board of Directors established a Task Force on Clinical Pathways, charged with articulating a set of recommendations to improve the development of oncology pathways and processes, allowing the demonstration of pathway concordance in a manner that promotes evidence-based, high-value care respecting input from patients, payers, and providers. These recommendations have been approved and adopted by ASCO's Board of Directors on August 12, 2015, and are presented herein. PMID:26759491

    Langer, F; Holstein, K; Eifrig, B; Bokemeyer, C

    2008-12-01

    The clinical link between cancer and thrombosis has been recognized by Armand Trousseau in 1865. It has now become clear that clotting activation in malignancy not only plays an important role in the evolution of venous thromboembolism (VTE) or systemic coagulation disorders such as disseminated intravascular coagulation, but that multiple components of the haemostatic and fibrinolytic systems are directly involved in tumour progression. In particular, tissue factor (TF) appears to be involved in several pathways relevant to cancer growth and metastasis. Increasing evidence emerges that haemostatic perturbances in cancer patients are, at least in part, controlled by defined genetic events in molecular tumourigenesis including activating and inactivating mutations of oncogenes and tumour suppressor genes, respectively. Long-term therapy with low-molecular-weight heparin (LMWH) is considered as standard treatment for cancer-associated VTE. However, several experimental studies and clinical trials suggest that LMWH may also be beneficial as an adjunct in the treatment of patients with malignant disease. This article provides an overview on the significance, pathogenesis and treatment of cancer-related clotting disorders as well as on the cellular and molecular mechanisms, by which haemostatic components such as TF, platelets and fibrin(ogen) drive tumour progression.

    Janeway, Katherine A; Place, Andrew E; Kieran, Mark W; Harris, Marian H

    2013-05-20

    The somatic genomic alterations in pediatric cancers to some extent overlap with those seen in adult cancers, but the exact distribution throughout the genome and the types and frequency of alterations differ. The ultimate goal of genomic research in children, as with adults, is translation to the clinic to achieve more accurate diagnosis, more precise risk stratification, and more effective, less toxic therapy. The genomic features of pediatric malignancies and pediatric-specific issues in clinical investigation may make translating genomic discoveries to the clinic more difficult. However, through large-scale molecular profiling of pediatric tumors, continued coordinated efforts to evaluate novel therapies in the pediatric population, thoughtful phase II and III trial design, and continued drug development, genomically based therapies will become more common in the pediatric oncology clinic in the future.

  14. A clinical intranet model for radiation oncology

    International Nuclear Information System (INIS)

    Purpose: A new paradigm in computing is being formulated from advances in client-server technology. This new way of accessing data in a network is referred to variously as Web-based computing, Internet computing, or Intranet computing. The difference between an internet and intranet being that the former is for global access and the later is only for intra-departmental access. Our purpose with this work is to develop a clinically useful radiation oncology intranet for accessing physically disparate data sources. Materials and Methods: We have developed an intranet client-server system using Windows-NT Server 4.0 running Internet Information Server (IIS) on the back-end and client PCs using a typical World Wide Web (WWW) browser. The clients also take advantage of the Microsoft Open Database Connectivity (ODBC) standard for accessing commercial database systems. The various data sources used include: a traditional Radiation Oncology Information (ROIS) System (VARiS 1.3tm); a 3-D treatment planning system (CAD Plantm); a beam scanning system (Wellhoffertm); as well as an electronic portal imaging device (PortalVisiontm) and a CT-Simulator providing digitally reconstructed radiographs (DRRs) (Picker AcQsimtm). We were able to leverage previously developed Microsoft Visual C++ applications without major re-writing of source code for this. Results: With the data sources and development materials used, we were able to develop a series of WWW-based clinical tool kits. The tool kits were designed to provide profession-specific clinical information. The physician's tool kit provides a treatment schedule for daily patients along with a dose summary from VARiS and the ability to review portal images and prescription images from the EPID and Picker. The physicists tool kit compares dose summaries from VARiS with an independent check against RTP beam data and serves as a quick 'chart-checker'. Finally, an administrator tool kit provides a summary of periodic charging

    The essential trace element selenium, which is a crucial cofactor in the most important endogenous antioxidative systems of the human body, is attracting more and more the attention of both laypersons and expert groups. The interest of oncologists mainly focuses in the following clinical aspects: radioprotection of normal tissues, radiosensitizing in malignant tumors, antiedematous effect, prognostic impact of selenium, and effects in primary and secondary cancer prevention. Selenium is a constituent of the small group of selenocysteine-containing selenoproteins and elicits important structural and enzymatic functions. Selenium deficiency has been linked to increased infection risk and adverse mood states. It has been shown to possess cancer-preventive and cytoprotective activities in both animal models and humans. It is well established that Se has a key role in redox regulation and antioxidant function, and hence in membrane integrity, energy metabolism and protection against DNA damage. Recent clinical trials have shown the importance of selenium in clinical oncology. Our own clinical study involving 48 patients suggest that selenium has a positive effect on radiation-associated secondary lymphedema in patients with limb edemas, as well as in the head and neck region, including endolaryngeal edema. Another randomized phase III study of our group was performed to examine the cytoprotective properties of selenium in radiation oncology. The aim was to evaluate whether sodium selenite is able to compensate a preexisting selenium deficiency and to prevent radiation induced diarrhea in adjuvant radiotherapy for pelvic gynecologic malignancies. Through this study, the significant benefits of sodium selenite supplementation with regards to selenium deficiency and radiotherapy induced diarrhea in patients with cervical and uterine cancer has been shown for the first time in a prospective randomized trial. Survival data imply that supplementation with selenium does not

    Biological oncology products are integral to cancer treatment, but their high costs pose challenges to patients, families, providers, and insurers. The introduction of biosimilar agents—molecules that are similar in structure, function, activity, immunogenicity, and safety to the original biological drugs—provide opportunities both to improve healthcare access and outcomes, and to reduce costs. Several international regulatory pathways have been developed to expedite entry of biosimilars into global marketplaces. The first wave of oncology biosimilar use was in Europe and India in 2007. Oncology biosimilars are now widely marketed in several countries in Europe, and in Australia, Japan, China, Russia, India, and South Korea. Their use is emerging worldwide, with the notable exception of the USA, where several regulatory and cost barriers to biosimilar approval exist. In this Review, we discuss oncology biosimilars and summarise their regulatory frameworks, clinical experiences, and safety concerns. PMID:25456378

    Integrative medicine is the combined use of complementary and alternative medicine with conventional or traditional Western medicine systems. The demand for integrative veterinary medicine is growing, but evidence-based research on its efficacy is limited. In veterinary clinical oncology, such research could be translated to human medicine, because veterinary patients with spontaneous tumors are valuable translational models for human cancers. An overview of specific herbs, botanics, dietary supplements, and acupuncture evaluated in dogs, in vitro canine cells, and other relevant species both in vivo and in vitro is presented for their potential use as integrative therapies in veterinary clinical oncology.

Several treatment modalities, such as surgery, glycolytic inhibition, driving CSC proliferation, immunotherapy, and hypofractionated radiotherapy, may have the potential to eradicate CSCs. We propose that monitoring CSCs is important in clinical oncology as CSC populations may reflect true treatment response and assist with managing treatment strategies, such as defining optimal chemotherapy cycles, permitting pretreatment cancer surveillance, conducting a comprehensive treatment plan, modifying radiation treatment, and deploying rechallenge chemotherapy. Then, we describe methods for monitoring CSCs. Keywords: cancer stem cells, glycolytic inhibition, watchful waiting, rechallenge, immunotherapy

    In human medicine clinical trials are legally required for drug development and approval. In contrast, clinical trials in small animal cancer patients are less common and legally perceived as animal experiments. Comparative oncology has been recognized as a method to speed up the development of medications by introducing animal patients with naturally developing tumours. In such cases, using animal patients would generate more robust data, as their spontaneous disease resembles the “real life...

    Hybrid imaging with integrated positron emission tomography (PET) and magnetic resonance imaging (MRI) combines the advantages of the high-resolution anatomic data from MRI and functional imaging data from PET, and has the potential to improve the diagnostic evaluation of various types of cancers. The clinical oncologic applications of this newest hybrid imaging technology are evolving and substantial efforts are underway to define the role of PET/MRI in routine clinical use. The current published literature suggests that PET/MRI may play an important role in the evaluation of patients with certain types of malignancies, involving anatomic locations such as the pelvis and the liver. The purpose of this article is to review the current published PET/MRI literature in specific body oncologic applications. In addition, PET/MRI protocols and some of the technical issues of this hybrid imaging will be briefly discussed. J. Magn. Reson. Imaging 2016;44:265-276. PMID:27007987

    Full Text Available The National Cancer Institute clinical cooperative groups have been instrumental over the past 50 years in developing clinical trials and evidence based process improvements for clinical oncology patient care. The cooperative groups are undergoing a transformation process as we further integrate molecular biology into personalized patient care and move to incorporate international partners in clinical trials. To support this vision, data acquisition and data management informatics tools must become both nimble and robust to support transformational research at an enterprise level. Information, including imaging, pathology, molecular biology, radiation oncology, surgery, systemic therapy and patient outcome data needs to be integrated into the clinical trial charter using adaptive clinical trial mechanisms for design of the trial. This information needs to be made available to investigators using digital processes for real time data analysis. Future clinical trials will need to be designed and completed in a timely manner facilitated by nimble informatics processes for data management. This paper discusses both past experience and future vision for clinical trials as we move to develop data management and quality assurance processes to meet the needs of the modern trial.

    Systematic studies evaluating clinical benefit of tumor genomic profiling are lacking. We conducted a prospective study in 250 patients with select solid tumors at the Cleveland Clinic. Eligibility required histopathologic diagnosis, age of 18 years or older, Eastern Cooperative Oncology Group performance status 0-2, and written informed consent. Tumors were sequenced using FoundationOne (Cambridge, MA). Results were reviewed at the Cleveland Clinic Genomics Tumor Board. Outcomes included feasibility and clinical impact. Colorectal (25%), breast (18%), lung (13%), and pancreatobiliary (13%) cancers were the most common diagnoses. Median time from consent to result was 25 days (range = 3-140). Of 223 evaluable samples, 49% (n = 109) of patients were recommended a specific therapy, but only 11% (n = 24) received such therapy: 12 on clinical trials, nine off-label, three on-label. Lack of clinical trial access (n = 49) and clinical deterioration (n = 29) were the most common reasons for nonrecommendation/nonreceipt of genomics-driven therapy.

    Cleeland, Charles S; O'Mara, Ann; Zagari, Martin; Baas, Carole

    2011-11-01

    Cancer-related pain is highly prevalent and often severe, and as a result is often one of the defining experiences for patients with malignancy. Patients and patients' families almost always live with the ever-present reality that cancer treatment and progression may be accompanied by pain. For patients nearing the end of life, most fear that their final days will be spent living with the terrible effects of the disease, the most important of which is pain. Despite this, there is far less systematic research on the mechanisms of cancer-related pain or on the development of new agents to reduce or eliminate pain in cancer patients compared with research to combat the disease itself. Further, even when the focus of research is treatment of the tumor, the effects of anticancer treatments on pain are often underreported in publications and other forums. To illustrate the relative drought in the cancer pain control area, there have been no new drugs approved for cancer-related pain in recent years. A number of methodologic and logistical challenges that hinder the ability to assess pain response in clinical trials are discussed in this article. Possible ways to address these challenges are also discussed. PMID:22046026

    The clinical development of molecularly targeted cancer therapies is enhanced by proof of mechanism of action as well as proof of concept, which relate molecular pharmacodynamics to efficacy via changes in cancer cell biology and physiology resulting from drug action on its intended target. Here, we present an introduction to the field of clinical pharmacodynamics, its medical and laboratory aspects, and its practical incorporation into clinical trials. We also describe key success factors that are useful for judging the quality of clinical pharmacodynamic studies, including biopsy quality and suitability, specimen handling, assay fitness-for-purpose, and reagent quality control. This introduction provides not only context for the following articles in this issue, but also an appreciation of the role of well-conducted clinical pharmacodynamic studies in oncology drug development.

    In this article, we present a case study of residents' clinical experiences and communication in outpatient oncology consultations. We apply positioning theory, a dynamic alternative to role theory, to investigate how oncology residents and patients situate themselves as persons with rights and duties. Drawing from seven qualitative interviews and six days of observation, we investigate the residents' social positioning and their conversations with patients or supervisors. Our focus is on how (a) relational shifts in authority depend on each situation and its participants; (b) storylines establish acts and positions and narratively frame what participants can expect from a medical consultation viewed as a social episode; and (c) the positioning of rights and duties can lead to misunderstandings and frustrations. We conclude that residents and patients locate themselves in outpatient conversations as participants who jointly produce and are produced by patients' and nurses' storylines about who should take responsibility for treatment.

    Treatment with monoclonal antibodies is becoming increasingly important in clinical oncology. These antibodies specifically inhibit signaling pathways in tumor growth and/or induce immunological responses against tumor cells. By combining monoclonal antibodies several pathways may be targeted simultaneously, potentially leading to additive or synergistic effects. Theoretically, antibodies are very suitable for use in combination therapy, because of limited overlapping toxicity and lack of pharmacokinetic interactions. In this article an overview is given of preclinical and clinical data on twenty-five different combinations of antibodies in oncology. Some of these combinations have proven clinical benefit, for example the combination of trastuzumab and pertuzumab in HER2-positive breast cancer, which exemplifies an additive or synergistic effect on antitumor activity in clinical studies and the combination of nivolumab and ipilimumab, which results in significant increases in progression-free and overall survival in patients with advanced melanoma. However, other combinations may lead to unfavorable results, such as bevacizumab with cetuximab or panitumumab in advanced colorectal cancer. These combinations result in shorter progression-free survival and increased toxicity compared to therapy with a single antibody. In summary, the different published studies showed widely varying results, depending on the combination of antibodies, indication and patient population. More preclinical and clinical studies are necessary to unravel the mechanisms behind synergistic or antagonistic effects of combining monoclonal antibodies. Most research on combination therapies is still in an early stage, but it is expected that for several tumor types the use of combination therapy of antibodies will become standard of care in the near future.

    2011-01-01

    Clinical microdialysis allows a discrete volume of the brain to be sampled for neurochemical analysis of neurotransmitters, metabolites, biomarkers, and drugs. The technique can be safely used in humans intraoperatively, in the intensive care unit, and in ambulatory settings. Microdialysis probes, micropumps, and analytical equipment are commercially available and have been used extensively for neurochemical monitoring in traumatic brain injury, stroke, and subarachnoid hemorrhage. There has been very limited use of micredialysis in neuro-oncology, but this technique has groat promise in the study of the basic neurochemistry of brain tumors, alterations in neurochemistry in response to therapy, and the pharmacokinetics of chemotherapeutic agents. Microdialysis probes may also be used to deliver drugs while simultaneously permitting monitoring of neurochemical changes induced by this therapy.

    Contract research organizations (CROs) represent a multibillion dollar industry that is firmly embedded in the contemporary clinical trial process. Over the past 30 years, and especially within the last decade, the reach of CROs has extended to service all phases of drug trials in an increasingly global research environment. The presence of CROs is particularly noticeable in medical oncology because of the large number of investigational compounds developed to treat cancer that are currently undergoing testing in human subjects. Although limited data are available with which to objectively define the effects that CROs have had on the clinical trial process, with the expansion of these organizations, several reports have called into question whether ethical and professional standards in research conduct are at times secondary to economic considerations. CROs can add considerable value to the clinical trial process, but difficulty communicating with CRO representatives and time spent answering trivial data queries generated by CROs are current obstacles for study site personnel interacting with CROs. Further study of the effect of the CRO industry on the clinical trial process is needed to ensure efficient data collection and patient safety while collaboratively developing novel therapies in an expedited fashion.

  16. A National Radiation Oncology Medical Student Clerkship Survey: Didactic Curricular Components Increase Confidence in Clinical Competency

    International Nuclear Information System (INIS)

    Purpose: Students applying to radiation oncology residency programs complete 1 or more radiation oncology clerkships. This study assesses student experiences and perspectives during radiation oncology clerkships. The impact of didactic components and number of clerkship experiences in relation to confidence in clinical competency and preparation to function as a first-year radiation oncology resident are evaluated. Methods and Materials: An anonymous, Internet-based survey was sent via direct e-mail to all applicants to a single radiation oncology residency program during the 2012-2013 academic year. The survey was composed of 3 main sections including questions regarding baseline demographic information and prior radiation oncology experience, rotation experiences, and ideal clerkship curriculum content. Results: The survey response rate was 37% (70 of 188). Respondents reported 191 unique clerkship experiences. Of the respondents, 27% (19 of 70) completed at least 1 clerkship with a didactic component geared towards their level of training. Completing a clerkship with a didactic component was significantly associated with a respondent's confidence to function as a first-year radiation oncology resident (Wilcoxon rank–sum P=.03). However, the total number of clerkships completed did not correlate with confidence to pursue radiation oncology as a specialty (Spearman ρ P=.48) or confidence to function as a first year resident (Spearman ρ P=.43). Conclusions: Based on responses to this survey, rotating students perceive that the majority of radiation oncology clerkships do not have formal didactic curricula. Survey respondents who completed a clerkship with a didactic curriculum reported feeling more prepared to function as a radiation oncology resident. However, completing an increasing number of clerkships does not appear to improve confidence in the decision to pursue radiation oncology as a career or to function as a radiation oncology resident. These results

  19. Clinical Training of Medical Physicists Specializing in Radiation Oncology

    International Nuclear Information System (INIS)

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for radiation therapy. There is a general and growing awareness that radiation medicine is increasingly dependant on well trained medical physicists that are based in the clinical setting. However an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognised by the members of the Regional Cooperative Agreement (RCA) for research, development and training related to nuclear sciences for Asia and the Pacific. Consequently a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specialising in radiation therapy was started in 2005 with the appointment of a core drafting committee of regional and international experts. Since 2005 the IAEA has convened two additional consultant group meetings including additional experts to prepare the present publication. The publication drew heavily, particularly in the initial stages, from the experience and documents of the Clinical Training Programme for Radiation Oncology Medical Physicists as developed by the Australasian College of Physical Scientists and Engineers in Medicine.

  1. Cancer-related fatigue. Clinical practice guidelines in oncology.

    Science.gov (United States)

    2003-07-01

    These guidelines propose a treatment algorithm in which patients are evaluated regularly for fatigue using a brief screening instrument, and are treated as indicated by their fatigue level. The algorithm's goal is to identify and treat all patients with fatigue that causes distress or interferes with their daily activities or functioning. Management of fatigue begins with primary oncology team members who perform the initial screening and either provide basic education and counseling or expand the initial screening to a more focused evaluation for moderate or higher levels of fatigue. At this point the patient is assessed for current disease and treatment status, a review of body systems, and an in-depth fatigue evaluation. In addition, the patient is assessed for the presence of seven treatable factors known to contribute to fatigue: pain, emotional distress, sleep disturbance, anemia, alterations in nutrition, deconditioning, and comorbidities. If any of these conditions are present, they should be treated according to practice guidelines, with referral to other care professionals as appropriate, and the patient's fatigue should be reevaluated regularly. If none of the seven factors are present or the fatigue is unresolved, selection of appropriate fatigue management and treatment strategies is considered within the context of the patient's clinical status: receiving active cancer treatment, receiving disease-free long-term follow-up, or receiving care at the end of life. Management of fatigue is cause-specific when conditions known to cause fatigue can be identified and treated. When specific causes, such as infection, fluid and electrolyte imbalances, or cardiac dysfunction, cannot be identified and corrected, nonpharmacologic and pharmacologic treatment of the fatigue should be considered. Nonpharmacologic interventions may include a moderate exercise program to improve functional capacity and activity tolerance, psychosocial programs to manage stress and

    Oncological treatments can lead to acute and chronic cancer related toxicities. In recent years, a large number of clinical studies have reported positive effects of exercise to the bio-psycho-social regeneration of cancer patients. However, very few evidence-based programs have been implemented into practice with little opportunity for cancer patients to engage in such programs. Reviews and RCT studies on exercise and cancer are showing that specific exercise programs have a positive impact on fatigue syndrome, urinary incontinence, lymphedema, polyneuropathy, arthralgia, and androgen deprivation related toxicities. With the increasing evidence for exercise oncology interventions, recommendations arising from clinical trials should be translated into clinical practice and this should be viewed as an important next step in this fast moving field of exercise oncology. For that the personalized treatment concept "Oncologic clinical exercise" (OTT) was developed. PMID:26402184

  4. Guide to clinical PET in oncology: Improving clinical management of cancer patients

    International Nuclear Information System (INIS)

    Positron emission tomography (PET) has an approximately 50 year-history. It was developed as a tool of medical science to quantitatively measure metabolic rates of bio-substances in vivo and in particular the number of receptors in neuroscience. Until the late 1990s PET was, in most cases, research oriented activity. In 2001, positron emission tomography/X ray computed tomography (PET/CT) hybrid imaging system became commercially available. An era of clinical PET then emerged, in which PET images were utilized for clinical practice in the treatment and diagnosis of cancer patients. PET imaging could recognize areas of abnormal metabolic behaviour of cancers in vivo, and the addition of CT imaging underlines the site of malignancy. More accurate and precise interpretation of cancer lesions can therefore be performed by PET/CT imaging than PET or CT imaging alone. Clinical PET, in particular with fluorine-18-fluorodeoxyglucose (18F-FDG), has already proven itself to have considerable value in oncology. The indications include malignant lymphoma and melanoma, head and neck cancers, oesophageal cancer, breast cancer, lung cancer and colorectal cancer, and it is still being expanded. The roles of clinical PET could be for 1) preoperative staging of cancers, 2) differentiation between residual tumour and scarring, 3) demonstration of suspected recurrences, 4) monitoring response to therapy, 5) prognosis and 6) radiotherapy treatment planning. Clinical PET can be used to illustrate exactly which treatment should be applied for a cancer patient as well as where surgeons should operate and where radiation oncologists should target radiation therapy. An almost exponential rise in the introduction of clinical PET, as well as the installation of PET/CT has been seen throughout the world. Clinical PET is currently viewed as the most powerful diagnostic tool in its field. This IAEA-TECDOC presents an overview of clinical PET for cancer patients and a relevant source of

    Non-clinical studies are necessary at each stage of the development of oncology drugs. Many experimental cancer models have been developed to investigate carcinogenesis, cancer progression, metastasis, and other aspects in cancer biology and these models turned out to be useful in the efficacy evaluation and the safety prediction of oncology drugs. While the diversity and the degree of engagement in genetic changes in the initiation of cancer cell growth and progression are widely accepted, it has become increasingly clear that the roles of host cells, tissue microenvironment, and the immune system also play important roles in cancer. Therefore, the methods used to develop oncology drugs should continuously be revised based on the advances in our understanding of cancer. In this review, we extensively summarize the effective use of those models, their advantages and disadvantages, ranges to be evaluated and limitations of the models currently used for the development and for the evaluation of oncology drugs.

    2015-01-01

    In the era of personalized medicine, diagnostic approaches are helping pharmaceutical and biotechnology sponsors streamline the clinical trial process. Molecular assays and diagnostic imaging are routinely being used to stratify patients for treatment, monitor disease, and provide reliable early clinical phase assessments. The importance of diagnostic approaches in drug development is highlighted by the rapidly expanding global cancer diagnostics market and the emergent attention of regulatory agencies worldwide, who are beginning to offer more structured platforms and guidance for this area. In this paper, we highlight the key benefits of using companion diagnostics and diagnostic imaging with a focus on oncology clinical trials. Nuclear imaging using widely available radiopharmaceuticals in conjunction with molecular imaging of oncology targets has opened the door to more accurate disease assessment and the modernization of standard criteria for the evaluation, staging, and treatment responses of cancer patients. Furthermore, the introduction and validation of quantitative molecular imaging continues to drive and optimize the field of oncology diagnostics. Given their pivotal role in disease assessment and treatment, the validation and commercialization of diagnostic tools will continue to advance oncology clinical trials, support new oncology drugs, and promote better patient outcomes.

    The introduction of hybrid PET/MRI systems allows simultaneous multimodality image acquisition of high technical quality. This technique is well suited for the brain, and particularly in dementia and neuro-oncology. In routine use combinations of well-established MRI sequences and PET tracers provide the most optimal and clinically valuable protocols. For dementia the [18F]-fluorodeoxyglucose (FDG) has merit with a simultaneous four sequence MRI protocol of 20 min supported by supplementary statistical reading tools and quantitative measurements of the hippocampal volume. Clinical PET/MRI using [18F]-fluoro-ethyl-tyrosine (FET) also abide to the expectations of the adaptive and versatile diagnostic tool necessary in neuro-oncology covering both simple 20 min protocols for routine treatment surveillance and complicated 90 min brain and spinal cord protocols in pediatric neuro-oncology under general anesthesia. The clinical value of adding advanced MRI sequences in multiparametric imaging setting, however, is still undocumented. PMID:27593248

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

    2000-06-01

    The SPIE Education Committee has developed an outreach program aimed at enhancing the dissemination of information about optics to children in kindergarten through the 12th grade (K-12). The main impetus behind the program was that more practicing optical scientists and engineers would be willing to give lectures and demonstrations aimed at inspiring the next generation about optics if material could be made easily available. Consequently, three instructional `outreach kits' were assembled to use in teaching optics to kids in exciting and fun ways. These kits were beta-tested over the last two years at six different U.S. regional sites. Each `outreach kit' contained: (1) a workbook on Optical Demonstrations on the Overhead Projector; (2) a Science and Math Experience Manual: Light, Color and Their Uses; (3) The Optics Discovery Classroom Kit; (4) a slide show; and (5) a video on careers in optics. The best tests were aimed at evaluating the practical ways of utilizing the kits, developing easy-to-follow instructions for guiding others in their use and providing suggestions on modifications, additions, and deletions to the kits. This paper discuses this outreach program and provides details relative to the kit's composition and future plans.

    Organized according to the role of FDG PET/CT in the evaluation and management of oncology patients. 100 informative cases reflecting the issues that clinicians address in their daily practice. Ideal for all newcomers to the field, whether medical students, radiology, nuclear medicine, or oncology fellows, or practicing physicians. FDG PET/CT has rapidly emerged as an invaluable combined imaging modality that can identify tumors on the basis of not only anatomical alterations but also metabolic activity, thus allowing the detection of lesions that would otherwise be too small to distinguish. This book, comprising a collection of images from oncology cases, is organized according to the role of FDG PET/CT in the evaluation and management of oncology patients, and only secondarily by organ or tumor entity. In this way, it reflects the issues that clinicians actually address in their daily practice, namely: identification of an unknown or unsuspected primary; determination of the extent of disease; evaluation of response to therapy; and surveillance after response, i.e., detection of recurrent disease. In total, 100 cases involving different primary tumors are presented to illustrate findings in these different circumstances. FDG PET/CT in Clinical Oncology will be of great value to all newcomers to this field, whether medical students, radiology, nuclear medicine, or oncology fellows, or practicing physicians.

  2. Making the right software choice for clinically used equipment in radiation oncology

    International Nuclear Information System (INIS)

    The customer of a new system for clinical use in radiation oncology must consider many options in order to find the optimal combination of software tools. Many commercial systems are available and each system has a large number of technical features. However an appraisal of the technical capabilities, especially the options for clinical implementations, is hardly assessable at first view. The intention of this article was to generate an assessment of the necessary functionalities for high precision radiotherapy and their integration in ROKIS (Radiation oncology clinic information system) for future customers, especially with regard to clinical applicability. Therefore we analysed the clinically required software functionalities and divided them into three categories: minimal, enhanced and optimal requirements for high conformal radiation treatment

  3. A critical appraisal of the clinical utility of proton therapy in oncology

    Full Text Available Dongxu WangDepartment of Radiation Oncology, University of Iowa Hospitals and Clinics, Iowa City, IA, USAAbstract: Proton therapy is an emerging technology for providing radiation therapy to cancer patients. The depth dose distribution of a proton beam makes it a preferable radiation modality as it reduces radiation to the healthy tissue outside the tumor, compared with conventional photon therapy. While theoretically beneficial, its clinical values are still being demonstrated from the increasing number of patients treated with proton therapy, from several dozen proton therapy centers around the world. High equipment and facility costs are often the major obstacle for its wider adoption. Because of the high cost and lack of definite clinical evidence of its superiority, proton therapy treatment faces criticism on its cost-effectiveness. Technological development is causing a gradual lowering of costs, and research and clinical studies are providing further evidence on its clinical utility.Keywords: proton therapy, radiation, cancer, oncology

  6. Assessing the Value of an Optional Radiation Oncology Clinical Rotation During the Core Clerkships in Medical School

    International Nuclear Information System (INIS)

    Purpose: Few medical students are given proper clinical training in oncology, much less radiation oncology. We attempted to assess the value of adding a radiation oncology clinical rotation to the medical school curriculum. Methods and Materials: In July 2010, Jefferson Medical College began to offer a 3-week radiation oncology rotation as an elective course for third-year medical students during the core surgical clerkship. During 2010 to 2012, 52 medical students chose to enroll in this rotation. The rotation included outpatient clinics, inpatient consults, didactic sessions, and case-based presentations by the students. Tests of students’ knowledge of radiation oncology were administered anonymously before and after the rotation to evaluate the educational effectiveness of the rotation. Students and radiation oncology faculty were given surveys to assess feedback about the rotation. Results: The students’ prerotation test scores had an average of 64% (95% confidence interval [CI], 61–66%). The postrotation test scores improved to an average of 82% (95% CI, 80–83%; 18% absolute improvement). In examination question analysis, scores improved in clinical oncology from 63% to 79%, in radiobiology from 70% to 77%, and in medical physics from 62% to 88%. Improvements in all sections but radiobiology were statistically significant. Students rated the usefulness of the rotation as 8.1 (scale 1–9; 95% CI, 7.3–9.0), their understanding of radiation oncology as a result of the rotation as 8.8 (95% CI, 8.5–9.1), and their recommendation of the rotation to a classmate as 8.2 (95% CI, 7.6–9.0). Conclusions: Integrating a radiation oncology clinical rotation into the medical school curriculum improves student knowledge of radiation oncology, including aspects of clinical oncology, radiobiology, and medical physics. The rotation is appreciated by both students and faculty.

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

    2016-03-01

    Phase I oncology clinical trials are designed to identify the optimal dose that will be recommended for phase II trials. In pediatric oncology, the conduct of those trials raises specific challenges, as the disease is rare with limited therapeutic options. In addition, the tolerance profile is known from adult trials. This paper provides a review of the major recent developments in the design of these trials, inspired by the need to cope with the specific challenges of dose finding in cancer pediatric oncology. We reviewed simulation studies comparing designs dedicated to address these challenges. We also reviewed the design used in published dose-finding trials in pediatric oncology over the period 2009-2014. Three main fields of innovation were identified. First, designs that were developed in order to relax the rules for more flexible inclusions. Second, methods to incorporate data emerging from adult studies. Third, designs accounting for toxicity evaluation at repeated cycles in pediatric oncology. In addition to this overview, we propose some further directions for designing pediatric dose-finding trials.

    Full Text Available Cellular heterogeneity is a fundamental characteristic of many cancers. A lack of cellular homogeneity contributes to difficulty in designing targeted oncological therapies. Therefore, the development of novel methods to determine and characterize oncologic cellular heterogeneity is a critical next step in the development of novel cancer therapies. Single-cell sequencing (SCS technology has been recently employed for analyzing the genetic polymorphisms of individual cells at the genome-wide level. SCS requires (1 precise isolation of the single cell of interest; (2 isolation and amplification of genetic material; and (3 descriptive analysis of genomic, transcriptomic, and epigenomic data. In addition to targeted analysis of single cells isolated from tumor biopsies, SCS technology may be applied to circulating tumor cells, which may aid in predicting tumor progression and metastasis. In this paper, we provide an overview of SCS technology and review the current literature on the potential application of SCS to clinical oncology and research.

    Purpose: Workload level and sources of stressors have been implicated as sources of error in multiple settings. We assessed workload levels and sources of stressors among radiation oncology professionals. Furthermore, we explored the potential association between workload and the frequency of reported radiotherapy incidents by the World Health Organization (WHO). Methods and Materials: Data collection was aimed at various tasks performed by 21 study participants from different radiation oncology professional subgroups (simulation therapists, radiation therapists, physicists, dosimetrists, and physicians). Workload was assessed using National Aeronautics and Space Administration Task-Load Index (NASA TLX). Sources of stressors were quantified using observational methods and segregated using a standard taxonomy. Comparisons between professional subgroups and tasks were made using analysis of variance ANOVA, multivariate ANOVA, and Duncan test. An association between workload levels (NASA TLX) and the frequency of radiotherapy incidents (WHO incidents) was explored (Pearson correlation test). Results: A total of 173 workload assessments were obtained. Overall, simulation therapists had relatively low workloads (NASA TLX range, 30-36), and physicists had relatively high workloads (NASA TLX range, 51-63). NASA TLX scores for physicians, radiation therapists, and dosimetrists ranged from 40-52. There was marked intertask/professional subgroup variation (P<.0001). Mental demand (P<.001), physical demand (P=.001), and effort (P=.006) significantly differed among professional subgroups. Typically, there were 3-5 stressors per cycle of analyzed tasks with the following distribution: interruptions (41.4%), time factors (17%), technical factors (13.6%), teamwork issues (11.6%), patient factors (9.0%), and environmental factors (7.4%). A positive association between workload and frequency of reported radiotherapy incidents by the WHO was found (r = 0.87, P value=.045

    Since the beginning of its guidelines program in 1993, ASCO has continually sought ways to produce a greater number of guidelines while maintaining its commitment to using the rigorous development methods that minimize the biases that threaten the validity of practice recommendations. ASCO is implementing a range of guideline development and implementation innovations. In this article, we describe innovations that are designed to (1) integrate consideration of multiple chronic conditions into practice guidelines; (2) keep more of its guidelines current by applying evolving signals or (more) rapid, for-cause updating approaches; (3) increase the number of high-quality guidelines available to its membership through endorsement and adaptation of other groups' products; (4) improve coverage of its members' guideline needs through a new topic nomination process; and (5) enhance dissemination and promote implementation of ASCO guidelines in the oncology practice community through a network of volunteer ambassadors. We close with a summary of ASCO's plans to facilitate the integration of data from its rapid learning system, CancerLinQ, into ASCO guidelines and to develop tactics through which guideline recommendations can be embedded in clinicians' workflow in digital form. We highlight the challenges inherent in reconciling the need to provide clinicians with more interactive, point-of-care guidance with ASCO's abiding commitment to methodologic rigor in guideline development.

    Hierarchical processes spanning several orders of magnitude of both space and time underlie nearly all cancers. Multi-scale statistical, mathematical, and computational modeling methods are central to designing, implementing and assessing treatment strategies that account for these hierarchies. The basic science underlying these modeling efforts is maturing into a new discipline that is close to influencing and facilitating clinical successes. The purpose of this review is to capture the state-of-the-art as well as the key barriers to success for multi-scale modeling in clinical oncology. We begin with a summary of the long-envisioned promise of multi-scale modeling in clinical oncology, including the synthesis of disparate data types into models that reveal underlying mechanisms and allow for experimental testing of hypotheses. We then evaluate the mathematical techniques employed most widely and present several examples illustrating their application as well as the current gap between pre-clinical and clinical applications. We conclude with a discussion of what we view to be the key challenges and opportunities for multi-scale modeling in clinical oncology. PMID:27384942

    Full Text Available Abstract We have reviewed the pivotal presentations related to gastrointestinal malignancies from 2009 annual meeting of the American Society of Clinical Oncology with the theme of "personalizing cancer care". We have discussed the scientific findings and the impact on practice guidelines and ongoing clinical trials. Adding trastuzumab to chemotherapy improved the survival of patients with advanced gastric cancer overexpressing human epidermal growth factor receptor 2. Gemcitabine plus cisplatin has become a new standard for first-line treatment of advanced biliary cancer. Octreotide LAR significantly lengthened median time to tumor progression compared with placebo in patients with metastatic neuroendocrine tumors of the midgut. Addition of oxaliplatin to fluoropyrimidines for preoperative chemoradiotherapy in patients with stage II or III rectal cancer did not improve local tumor response but increased toxicities. Bevacizumab did not provide additional benefit to chemotherapy in adjuvant chemotherapy for stage II or III colon cancer. In patients with resected stage II colon cancer, recurrence score estimated by multigene RT-PCR assay has been shown to provide additional risk stratification. In stage IV colorectal cancer, data have supported the routine use of prophylactic skin treatment in patients receiving antibody against epidermal growth factor receptor, and the use of upfront chemotherapy as initial management in patients with synchronous metastasis without obstruction or bleeding from the primary site.

  1. An exploration of the experience of compassion fatigue in clinical oncology nurses.

    2011-01-01

    Compassion fatigue (CF) is "debilitating weariness brought about by repetitive, empathic responses to the pain and suffering of others" (LaRowe, 2005, p. 21). The work performed by oncology nurses, and the experiences of the people they care for, place oncology nurses at high risk for CF (Pierce et al., 2007; Ferrell & Coyle, 2008). Thus oncology nurses were chosen as the study focus. This paper details a descriptive exploratory qualitative research study that investigated the experience of CF in Canadian clinical oncology registered nurses (RNs). A conceptual stress process model by Aneshensel, Pearlin, Mullan, Zarit, and Whitlatch (1995) that considers caregivers' stress in four domains provided the study framework (see Figure 1). Nineteen study participants were recruited through an advertisement in the Canadian Oncology Nursing Journal (CONJ). The advertisement directed potential participants to a university-based online website developed for this study. Participants completed a questionnaire and wrote a narrative describing an experience with CF and submitted these through the secure research website. Data were analyzed thematically. Five themes include: defining CF, causes of CF, factors that worsen CF, factors that lessen CF, and outcomes of CF. Participants had limited knowledge about CF, about lack of external support, and that insufficient time to provide high quality, care may precipitate CF. The gap between quality of care nurses wanted to provide and what they were able to do, compounded by coexisting physical and emotional stress, worsened CF. CF was lessened by colleague support, work-life balance, connecting with others, acknowledgement, and maturity and experience. Outcomes of CF included profound fatigue of mind and body, negative effects on personal relationships, and considering leaving the specialty. Recommendations that may enhance oncology nurse well-being are provided. PMID:21661623

    There is currently a rapid evolution of clinical practices based on the introduction of patient stratification and molecular diagnosis that is likely to improve health outcomes. Building on a strong research base, complemented by strong support from clinicians and health authorities, the oncology field is at the forefront of this evolution. Yet, clinical research is still facing many challenges that need to be addressed in order to conduct necessary studies and effectively translate medical breakthroughs based on personalized medicine into standards of care. Leveraging its universal health care system and on resources developed to support oncology clinical research, Canada is well positioned to join the international efforts deployed to address these challenges. Available resources include a broad range of structures and funding mechanisms, ranging from direct clinical trial support to post-marketing surveillance. Here, we propose a clinical model for the introduction of innovation for precision medicine in oncology that starts with patients' and clinicians' unmet needs to initiate a cycle of discovery, validation, translation and sustainability development.

In photoacoustic imaging, tissue is optically excited to produce ultrasonographic images that represent a spatial map of optical absorption of endogenous constituents such as hemoglobin, fat, melanin, and water or exogenous contrast agents such as dyes and nanoparticles. It can therefore provide functional and molecular information that allows noninvasive soft-tissue characterization. Photoacoustic imaging has matured over the years and is currently being translated into the clinic with various clinical studies underway. In this review, the current state of photoacoustic imaging is presented, including techniques and instrumentation, followed by a discussion of potential clinical applications of this technique for the detection and management of cancer.

    BACKGROUND: There is little evidence regarding attitudes to clinical decision support systems (CDSS) in oncology. AIMS: We examined the current usage, awareness, and concerns of Irish medical oncologists and oncology pharmacists in this area. METHODS: A questionnaire was sent to 27 medical oncologists and 34 oncology pharmacists, identified through professional interest groups. Respondents ranked concerns regarding their use of a CDSS on a scale from 1 to 4, with 4 being most important. RESULTS: Overall, 67% (41\\/61) responded, 48% (13\\/27) of oncologists and 82% (28\\/34) of pharmacists surveyed. Concerns included "difficulty defining complex clinical situations with a set of rules" (mean ± SD) (3.2 ± 0.9), "ensuring evidence base is up to date and relevant" (3.2 ± 0.9) and "lack of clinically relevant suggestions" (2.9 ± 0.9). Ninety-three percent reported using a CDSS but 54% were unaware of this. CONCLUSION: While there are benefits to using a CDSS, concerns must be addressed through user education. This may be a starting point for a user-centred design approach to the development of future local systems through a consultative process.

  12. Role of French teams in the development of clinical and translational research in radiation oncology

    International Nuclear Information System (INIS)

    Many clinical studies have showed the key role of radiotherapy in anticancer treatment strategy. Radiations are delivered alone or in combination with systemic therapies. In recent years, the main goal of all clinical developments has focused on improving clinical benefit, with an increased tumour control and a higher normal tissue protection. This research was designed to reduce local recurrences, to increase recurrence-free or overall survival and to decrease acute and late effects. Technological and biological evolutions (or revolutions) accompanied clinicians to improve clinical benefit, namely with strong progress in radiology and better understanding of radiobiology, particularly at the molecular level. Differences in tumour and normal tissues radiosensitivity are nowadays integrated in daily clinical practice of radiation oncologists. The current report details the last 5-year developments of clinical and translational research in radiation oncology, especially the role of French teams in the development of personalized treatment.

  13. Clinical perspectives of cancer stem cell research in radiation oncology

    International Nuclear Information System (INIS)

    Radiotherapy has a proven potential to eradicate cancer stem cells which is reflected by its curative potential in many cancer types. Considerable progress has been made in identification and biological characterisation of cancer stem cells during the past years. Recent biological findings indicate significant inter- and intratumoural and functional heterogeneity of cancer stem cells and lead to more complex models which have potential implications for radiobiology and radiotherapy. Clinical evidence is emerging that biomarkers of cancer stem cells may be prognostic for the outcome of radiotherapy in some tumour entities. Perspectives of cancer stem cell based research for radiotherapy reviewed here include their radioresistance compared to the mass of non-cancer stem cells which form the bulk of all tumour cells, implications for image- and non-image based predictive bio-assays of the outcome of radiotherapy and a combination of novel systemic treatments with radiotherapy

    Full Text Available Abstract During the past decade, genomic microarrays have been applied with some success to the molecular profiling of breast tumours, which has resulted in a much more detailed classification scheme as well as in the identification of potential gene signature sets. These gene sets have been applied to both the prognosis and prediction of outcome to treatment and have performed better than the current clinical criteria. One of the main limitations of microarray analysis, however, is that frozen tumour samples are required for the assay. This imposes severe limitations on access to samples and precludes large scale validation studies from being conducted. Quantitative reverse transcriptase polymerase chain reaction (qRT-PCR, on the other hand, can be used with degraded RNAs derived from formalin-fixed paraffin-embedded (FFPE tumour samples, the most important and abundant source of clinical material available. More recently, the novel DASL (cDNA-mediated Annealing, Selection, extension and Ligation assay has been developed as a high throughput gene expression profiling system specifically designed for use with FFPE tumour tissue samples. However, we do not believe that genomics is adequate as a sole prognostic and predictive platform in breast cancer. The key proteins driving oncogenesis, for example, can undergo post-translational modifications; moreover, if we are ever to move individualization of therapy into the practical world of blood-based assays, serum proteomics becomes critical. Proteomic platforms, including tissue micro-arrays (TMA and protein chip arrays, in conjunction with surface-enhanced laser desorption ionization time-of-flight mass spectrometry (SELDI-TOF/MS, have been the technologies most widely applied to the characterization of tumours and serum from breast cancer patients, with still limited but encouraging results. This review will focus on these genomic and proteomic platforms, with an emphasis placed on the utilization

    Despite much progress in the management of malignant diseases, the number of new cases and cancer-related deaths continues to rise around the world. More than half of new cases occur in economically developing countries, where more than two thirds of cancer deaths are expected. However, implementation of all necessary steps to accomplish the dissemination of state-of-the-art prevention, diagnosis, and management will require increased allocation of resources, and, more importantly, harmonization of the efforts of hundreds of national and international public health agencies, policy-setting bodies, governments, pharmaceutical companies, and philanthropic organizations. More than 30% of the members of the American Society of Clinical Oncology (ASCO) reside and practice outside US borders, and more than half of attendees at all of the scientific congresses and symposia organized by ASCO are international. As cancer has become an increasingly global disease, ASCO has evolved as a global organization. The ASCO Board of Directors currently includes members from France, Brazil, and Canada. In 2013, the ASCO Board of Directors identified a number of strategic priorities for the future. Recognizing the importance of non-US members to the society, their first strategic priority was improving the society's service to non-US members and defining these members' identity in the international oncology community. This article reviews current ASCO activities in the international arena and its future plans in global oncology.

    2016-01-01

    The evidence base for the effectiveness of surgical interventions is relatively poor and data from large, randomized prospective studies are rare with often a poor quality. Many efforts have been made to increase the number of high quality randomized trials in surgery and theoretical proposals have been put forward to improve the situation, but practical implementation of these proposals is seriously lacking. The consequences of this policy are not trivial; with very few patients included in surgical oncology trials, this represents wasted opportunity for advances in cancer treatment. In this review, we cover the difficulties inherent to clinical research in surgical oncology, such as quality control, equipoise, accrual, and funding and promote alternative designs to the randomized controlled trial. Although the classic randomized controlled trial has a valid but limited place in surgical oncology, other prospective designs need to be promoted as a new deal. This new deal not only implicates surgeons but also journal editors, tender jury, as well as regulatory bodies to cover legal gaps currently surrounding surgical innovation.

    2016-07-01

    It is imperative that the thrust of clinical practice in the ensuing years would be to develop personalized management model for various disorders. PET-computed tomography (PET-CT) based molecular functional imaging has been increasingly utilized for assessment of tumor and other nonmalignant disorders and has the ability to explore disease phenotype on an individual basis and address critical clinical decision making questions related to practice of personalized medicine. Hence, it is essential to make a concerted systematic effort to explore and define the appropriate place of PET-CT in personalized clinical practice in each of malignancies, which would strengthen the concept further. The potential advantages of PET based disease management can be classified into broad categories: (1) Traditional: which includes assessment of disease extent such as initial disease staging and restaging, treatment response evaluation particularly early in the course and thus PET-CT response adaptive decision for continuing the same regimen or switching to salvage schedules; there has been continuous addition of newer application of PET based disease restaging in oncological parlance (eg, Richter transformation); (2) Recent and emerging developments: this includes exploring tumor biology with FDG and non-FDG PET tracers. The potential of multitracer PET imaging (particularly new and novel tracers, eg, 68Ga-DOTA-TOC/NOC/TATE in NET, 68Ga-PSMA and 18F-fluorocholine in prostate carcinoma, 18F-fluoroestradiol in breast carcinoma) has provided a scientific basis to stratify and select appropriate targeted therapies (both radionuclide and nonradionuclide treatment), a major boost for individualized disease management in clinical oncology. Integrating the molecular level information obtained from PET with structural imaging further individualizing treatment plan in radiation oncology, precision of interventions and biopsies of a particular lesion and forecasting disease prognosis.

    Answer questions and earn CME/CNE The purpose of the American Cancer Society/American Society of Clinical Oncology Breast Cancer Survivorship Care Guideline is to provide recommendations to assist primary care and other clinicians in the care of female adult survivors of breast cancer. A systematic review of the literature was conducted using PubMed through April 2015. A multidisciplinary expert workgroup with expertise in primary care, gynecology, surgical oncology, medical oncology, radiation oncology, and nursing was formed and tasked with drafting the Breast Cancer Survivorship Care Guideline. A total of 1073 articles met inclusion criteria; and, after full text review, 237 were included as the evidence base. Patients should undergo regular surveillance for breast cancer recurrence, including evaluation with a cancer-related history and physical examination, and should be screened for new primary breast cancer. Data do not support performing routine laboratory tests or imaging tests in asymptomatic patients to evaluate for breast cancer recurrence. Primary care clinicians should counsel patients about the importance of maintaining a healthy lifestyle, monitor for post-treatment symptoms that can adversely affect quality of life, and monitor for adherence to endocrine therapy. Recommendations provided in this guideline are based on current evidence in the literature and expert consensus opinion. Most of the evidence is not sufficient to warrant a strong evidence-based recommendation. Recommendations on surveillance for breast cancer recurrence, screening for second primary cancers, assessment and management of physical and psychosocial long-term and late effects of breast cancer and its treatment, health promotion, and care coordination/practice implications are made.

  20. Clinical PET/CT Atlas: A Casebook of Imaging in Oncology

    International Nuclear Information System (INIS)

    Integrated positron emission tomography/computed tomography (PET/CT) has evolved since its introduction into the commercial market more than a decade ago. It is now a key procedure, particularly in oncological imaging. Over the last years in routine clinical service, PET/CT has had a significant impact on diagnosis, treatment planning, staging, therapy, and monitoring of treatment response and has therefore played an important role in the care of cancer patients. The high sensitivity from the PET component and the specificity of the CT component give this hybrid imaging modality the unique characteristics that make PET/CT, even after over 10 years of clinical use, one of the fastest growing imaging modalities worldwide. This publication combines over 90 comprehensive cases covering all major indications of fluorodeoxyglucose (18F-FDG)-PET/CT as well as some cases of clinically relevant special tracers. The cases provide an overview of what the specific disease can look like in PET/CT, the typical pattern of the disease’s spread as well as likely pitfalls and teaching points. This PET/CT Atlas will allow professionals interested in PET/CT imaging to embrace the variety of oncological imaging by providing clinically relevant teaching files on the effectiveness and diagnostic quality of FDG-PET/CT imaging in routine applications

    This Vision 20/20 paper considers what computational advances are likely to be implemented in clinical radiation oncology in the coming years and how the adoption of these changes might alter the practice of radiotherapy. Four main areas of likely advancement are explored: cloud computing, aggregate data analyses, parallel computation, and automation. As these developments promise both new opportunities and new risks to clinicians and patients alike, the potential benefits are weighed against the hazards associated with each advance, with special considerations regarding patient safety under new computational platforms and methodologies. While the concerns of patient safety are legitimate, the authors contend that progress toward next-generation clinical informatics systems will bring about extremely valuable developments in quality improvement initiatives, clinical efficiency, outcomes analyses, data sharing, and adaptive radiotherapy.

Unpublished observations indicate that it can also antagonize the growth of other bacteria involved in acute otitis media. Because of its ability to colonize the oral cavity and its safety profile, we have tested its efficacy in reducing the incidence of streptococcal pharyngitis and/or tonsillitis and episodes of acute otitis media.Methods: We enrolled 82 children, including 65 with and 17 without a recent diagnosis of recurrent oral streptococcal pathology. Of those with recurrent pathology, 45 were treated daily for 90 days with an oral slow-release tablet containing five billion colony-forming units of S. salivarius K12 (Bactoblis®, and the remaining 20 served as an untreated control group. The 17 children without a recent diagnosis of recurrent oral pathology were used as an additional control group. After 90 days of treatment, a 6-month follow-up period without treatment was included to evaluate a possible persistent protective role for the previously administered product.Results: The 41 children who completed the 90-day course of Bactoblis showed a reduction in their episodes of streptococcal pharyngeal infection (about 90% and/or acute otitis media (about 40%, calculated by comparing infection rates in the previous year. The 90-day treatment also reduced the reported incidence of pharyngeal and ear infections by about 65% in the 6-month follow-up period

    The oncology clinics use different nursing care delivery models to provide chemotherapy treatment to cancer patients. Functional and primary care delivery models are the most commonly used methods in the clinics. In functional care delivery model, patients are scheduled for a chemotherapy appointment without considering availabilities of individual nurses, and nurses are assigned to patients according to patient acuities, nursing skill, and patient mix on a given day after the appointment schedule is determined. Patients might be treated by different nurses on different days of their treatment. In primary care delivery model, each patient is assigned to a primary nurse, and the patients are scheduled to be seen by the same nurse every time they come to the clinic for treatment. However, these clinics might experience high variability in daily nurse workload due to treatment protocols that should be followed strictly. In that case, part-time nurses can be utilized to share the excess workload of the primary nurses. The aim of this study is to develop optimization methods to reduce the time spent for nurse assignment and patient scheduling in oncology clinics that use different nursing care delivery models. For the functional delivery model, a multiobjective optimization model with the objectives of minimizing patient waiting times and nurse overtime is proposed to solve the nurse assignment problem. For the primary care delivery model, another multiobjective optimization model with the objectives of minimizing total overtime and total excess workload is proposed to solve the patient scheduling problem. Spreadsheet-based optimization tools are developed for easy implementation. Computational results show that the proposed models provide multiple nondominated solutions, which can be used to determine the optimal staffing levels.

  12. Bioluminescent imaging: a critical tool in pre-clinical oncology research.

    O'Neill, Karen

    2010-02-01

    Bioluminescent imaging (BLI) is a non-invasive imaging modality widely used in the field of pre-clinical oncology research. Imaging of small animal tumour models using BLI involves the generation of light by luciferase-expressing cells in the animal following administration of substrate. This light may be imaged using an external detector. The technique allows a variety of tumour-associated properties to be visualized dynamically in living models. The increasing use of BLI as a small-animal imaging modality has led to advances in the development of xenogeneic, orthotopic, and genetically engineered animal models expressing luciferase genes. This review aims to provide insight into the principles of BLI and its applications in cancer research. Many studies to assess tumour growth and development, as well as efficacy of candidate therapeutics, have been performed using BLI. More recently, advances have also been made using bioluminescent imaging in studies of protein-protein interactions, genetic screening, cell-cycle regulators, and spontaneous cancer development. Such novel studies highlight the versatility and potential of bioluminescent imaging in future oncological research.

  13. Minimal-invasive core needle biopsy of head and neck malignancies: Clinical evaluation for radiation oncology

    International Nuclear Information System (INIS)

    Background and purpose: Neck masses are common presentations of cancer and require tissue sampling to establish a diagnosis prior to the institution of adequate therapy. The purpose of this study was to evaluate the specific use and potential advantages of core needle biopsy (CNB) for radiation oncology in the head and neck. Materials and methods: We performed a retrospective analysis of 346 CNB procedures implemented in 165 patients with cervicofacial masses over a period of 56 months. Seventy-three patients had a history of malignancy, 43 had previously received radiation. Results: High-quality tissue cores were obtained from all patients. The target lesion was correctly sampled in 92.1% of patients. Final diagnosis was malignant in 115 patients, of whom 78 received radiotherapy. One biopsy result was false-negative. CNB was equally successful in the pre-irradiated patients and enabled institution of therapy in 92.3% of lymphoma patients. Conclusions: CNB is an efficient tool for tissue sampling of head and neck masses. The potential advantages of CNB for radiation oncology over fine needle aspiration and open surgical biopsy are discussed. CNB enables clinicians to make optimal therapeutic strategies and facilitates prompt referral to the relevant clinical team, both at initial presentation and during follow-up

  14. Clinically unsuspected pulmonary embolism-an important secondary finding in oncology CT

    International Nuclear Information System (INIS)

    AIM: To determine the rate of finding incidental pulmonary embolisms (PE) at staging or follow-up chest computed tomography (CT) in oncology patients. MATERIALS AND METHODS: Three hundred and eighty-five consecutive chest CT examinations, performed in patients with cancer, were prospectively assessed during a 9-month period between October 2003 and June 2004. These were spiral acquisitions between 5 and 8 mm collimation acquired 25 s after intravenous contrast medium administration. PE was diagnosed if a filling defect was seen in the central pulmonary arteries on two or more consecutive slices. RESULTS: Ten of 385 (2.6%) of these patients had incidentally detected PE. This was not attributable to any specific malignancy or chemotherapeutic regimen. These emboli were all central, between the main pulmonary artery and the lobar level. Although the significance of these findings in patients not clinically suspected of having PE could be contentious, all the patients were started on therapeutic anticoagulation as a result of this observation. CONCLUSION: Over one in 40 oncology patients have incidental central PE visible on the CT images performed to assess their malignancy. Formal review of the pulmonary arteries, using a work station, is advised in patients with malignancy

    Racial and ethnic diversity has historically been difficult to achieve in National Cancer Institute-sponsored clinical trials, even while as many as 80% of those trials have faced difficulty in meeting overall recruitment targets. In an attempt to address these issues, NRG Oncology recently convened a comprehensive workshop titled "Clinical Trials Enrollment: Challenges and Opportunities." Discussants at the workshop included representatives of the three legacy groups of the NRG (ie, Gynecologic Oncology Group, National Surgical Adjuvant Breast and Bowel Program, and Radiation Therapy Oncology Group), a minority-based community clinical oncology program, a large integrated health care system, the leadership of the National Cancer Institute, and a large patient advocacy group. This article summarizes the concepts discussed at the workshop, which included: needs assessments, infrastructural support, training of investigators and research staff, specific clinical trial recruitment strategies (both system and community based), and development and mentoring of young investigators. Many new, more specific tactics, including use of diverse cancer care settings, direct-to-consumer communication, and the need for centralized information technology such as the use of software to match trials to special populations, are presented. It was concluded that new, innovative trial designs and the realities of limited funding would require the adoption of effective and efficient recruiting strategies, specialized training, and stakeholder engagement. US clinical research programs must generate and embrace new ideas and pilot test novel recruitment strategies if they are to maintain their historic role as world leaders in cancer care innovation and delivery.

    In May 1960, the Farmitalia CEO Dr. Bertini and the director of the Istituto Nazionale dei Tumori of Milan Prof. Bucalossi (talent scout and city's Mayor) signed a research agreement for the discovery and development up to clinical trials of new natural antitumor agents. This agreement can be considered as a pioneering and fruitful example of a translational discovery program with relevant transatlantic connections. Owing to an eclectic Streptomyces, found near Castel del Monte (Apulia), and to the skilled and motivated participants of both institutions, a new natural antitumor drug, daunomycin, was ready for clinical trials within 3 years. Patent interference by the Farmitalia French partner was overcome by the good quality of the Italian drug and by the cooperation between Prof. Di Marco, director of the Istituto Ricerche Farmitalia Research Laboratories for Microbiology and Chemotherapy, and Prof. Karnofsky, head of the Sloan-Kettering Cancer Institute of New York, leading to the first transatlantic clinical trials. The search for daunomycin's sister anthracyclines led to the discovery and development of adriamycin, one of the best drugs born in Milan. This was the second act prologue of the history of Italian antitumor discovery and clinical oncology, which started in July 1969 when Prof. Di Marco sent Prof. Bonadonna the first vials of adriamycin (doxorubicin) to be tested in clinical trials. This article reviews the Milan scene in the 1960s, a city admired and noted for the outstanding scientific achievements of its private and public institutions in drugs and industrial product discovery.

    2012-01-01

    Background The oral probiotic Streptococcus salivarius K12 has been shown clearly to antagonize the growth of Streptococcus pyogenes, the most important bacterial cause of pharyngeal infections in humans, by releasing two bacteriocins named salivaricin A2 and salivaricin B. Unpublished observations indicate that it can also antagonize the growth of other bacteria involved in acute otitis media. Because of its ability to colonize the oral cavity and its safety profile, we have tested its efficacy in reducing the incidence of streptococcal pharyngitis and/or tonsillitis and episodes of acute otitis media. Methods We enrolled 82 children, including 65 with and 17 without a recent diagnosis of recurrent oral streptococcal pathology. Of those with recurrent pathology, 45 were treated daily for 90 days with an oral slow-release tablet containing five billion colony-forming units of S. salivarius K12 (Bactoblis®), and the remaining 20 served as an untreated control group. The 17 children without a recent diagnosis of recurrent oral pathology were used as an additional control group. After 90 days of treatment, a 6-month follow-up period without treatment was included to evaluate a possible persistent protective role for the previously administered product. Results The 41 children who completed the 90-day course of Bactoblis showed a reduction in their episodes of streptococcal pharyngeal infection (about 90%) and/or acute otitis media (about 40%), calculated by comparing infection rates in the previous year. The 90-day treatment also reduced the reported incidence of pharyngeal and ear infections by about 65% in the 6-month follow-up period during which the product was not administered. Subjects tolerated the product well, with no side effects or dropouts reported. Conclusion Prophylactic administration of S. salivarius K12 to children with a history of recurrent oral streptococcal pathology reduced episodes of streptococcal pharyngeal infections and/or tonsillitis as

    Progression-free survival is an increasingly popular end point in oncology clinical trials. A complete blinded independent central review (BICR) is often required by regulators in an attempt to reduce the bias in progression-free survival (PFS) assessment. In this paper, we propose a new methodology that uses a sample-based BICR as an audit tool to decide whether a complete BICR is needed. More specifically, we propose a new index, the differential risk, to measure the reading discordance pattern, and develop a corresponding hypothesis testing procedure to decide whether the bias in local evaluation is acceptable. Simulation results demonstrate that our new index is sensitive to the change of discordance pattern; type I error is well controlled in the hypothesis testing procedure, and the calculated sample size provides the desired power.

    2013-08-01

    Full Text Available The Personalized Medicine approach in oncology is a direct result of an improved understanding of complex tumor biology and advances in diagnostic technologies. In recent years, there has been an increased demand for archival and fresh tumor analysis in early clinical trials to foster proof-of-concept biomarker development, to understand resistance mechanisms, and ultimately to assess biological response. Although phase I studies are aimed at defining drug safety, pharmacokinetics, and to recommend a phase II dose for further testing, there is now increasing evidence of mandatory tumor biopsies even at the earliest dose-finding stages of drug development. The increasing demand for fresh tumor biopsies adds to the complexity of novel phase I studies and results in different challenges, ranging from logistical support to ethical concerns. This paper investigates key issues, including patients’ perceptions of research biopsies, the need for accurate informed consent, and alternative strategies that may guide the drug development process.

    2011-06-01

    The use of targeted anti-cancer agents is increasing. It is common to utilize a multi-modal treatment approach towards solid tumors, often including surgical resection, and it has become apparent that some targeted agents can impair wound healing or cause an increased risk of perioperative complications. This article reviews targeted agents used in solid tumor oncology with an emphasis on clinically relevant details. Overall, the evidence of targeted agents causing surgical complications is limited. The greatest amount of evidence exists for bevacizumab causing perioperative complications, possibly due to its extended half-life. There are limited data for cetuximab, sorafenib and sunitinib and very little for other solid tumor targeted agents. Our findings suggest that there should be heightened pharmacovigilence around targeted agents with respect to perioperative complications and increased post-surgical support for patients to aid early detection of postoperative complications until definitive data become available.

    2015-11-10

    The American Society of Clinical Oncology (ASCO) convened a subcommittee to develop recommendations on improving the evidence base for treating older adults with cancer in response to a critical need identified by the Institute of Medicine. Older adults experience the majority of cancer diagnoses and deaths and make up the majority of cancer survivors. Older adults are also the fastest growing segment of the US population. However, the evidence base for treating this population is sparse, because older adults are underrepresented in clinical trials, and trials designed specifically for older adults are rare. The result is that clinicians have less evidence on how to treat older adults, who represent the majority of patients with cancer. Clinicians and patients are forced to extrapolate from trials conducted in younger, healthier populations when developing treatment plans. This has created a dearth of knowledge regarding the risk of toxicity in the average older patient and about key end points of importance to older adults. ASCO makes five recommendations to improve evidence generation in this population: (1) Use clinical trials to improve the evidence base for treating older adults with cancer, (2) leverage research designs and infrastructure for generating evidence on older adults with cancer, (3) increase US Food and Drug Administration authority to incentivize and require research involving older adults with cancer, (4) increase clinicians' recruitment of older adults with cancer to clinical trials, and (5) use journal policies to improve researchers' reporting on the age distribution and health risk profiles of research participants.

    Full Text Available Purpose: Because of its rarity in any oncology centre, the clinical trends of male breast cancer specific to its geographical distribution have remained relatively unexplored. This study was done to analyze the clinico-pathological data, treatment given and survival patterns of male breast cancer patients visiting our tertiary medical centre and compare our results with available literature. Methods: All male breast cancer patients registered at our clinic from 2003 to 2009 were included. Frequency distribution analysis of the demographic and clinico-pathological data and treatment variables was done. Treatment outcome was examined from Kaplan-Meir survival estimates. Results: Thirty-three male breast cancer patients were encountered. The median age of presentation was sixty years. Mostly (87.9% they presented with lump in breast or axilla and were clinically staged to be ‘3’ (57.6%.Obesity and alcohol were the commonest risk factors identified. Modified radical mastectomy was the commonest (69.6% definitive therapy rendered with (only for clinically staged 3 patients or without neo-adjuvant chemotherapy. Infiltrating ductal carcinoma was identified in most cases. Twenty-two patients received adjuvant chemotherapy and twenty-four received adjuvant radiotherapy.

    International Nuclear Information System (INIS)

    The Radiation Oncology Division has had as its main objectives both to operate an academic training program and to carry out research on radiation therapy of cancer. Since fiscal year 1975, following a directive from ERDA, increased effort has been given to research. The research activities have been complemented by the training program, which has been oriented toward producing radiation oncologists, giving physicians short-term experience in radiation oncology, and teaching medical students about clinical cancer and its radiation therapy. The purpose of the research effort is to improve present modalities of radiation therapy of cancer. As in previous years, the Division has operated as the Radiation Oncology Program of the Department of Radiological Sciences of the University of Puerto Rico School of Medicine. It has provided radiation oncology support to patients at the University Hospital and to academic programs of the University of Puerto Rico Medical Sciences Campus. The patients, in turn, have provided the clinical basis for the educational and research projects of the Division. Funding has been primarily from PRNC (approx. 40%) and from National Cancer Institute grants channeled through the School of Medicine (approx. 60%). Special inter-institutional relationships with the San Juan Veterans Administration Hospital and the Metropolitan Hospital in San Juan have permitted inclusion of patients from these institutions in the Division's research projects. Medical physics and radiotherapy consultations have been provided to the Radiotherapy Department of the VA Hospital

  8. The role of radiation therapy in pediatric oncology as assessed by cooperative clinical trials

    International Nuclear Information System (INIS)

    Major advances have been made in pediatric oncology, and many are due to the advent of the cooperative clinical trial. This important research tool was originally developed for the testing of various therapeutic strategies for the management of children with acute leukemia. Such trials were eminently successful, as the consistently better long-term survival rates for children with this hitherto uniformly lethal disease can attest. The method soon found favor for the investigation of patients with so-called solid tumors. These trails were originally concerned with the elucidation of the value of various chemotherapeutic agents. Radiation therapists soon became involved, however, and this discipline became more heavily represented in study design and data analyses. Much radiation therapy information has been gained, some through prospective, randomized clinical investigations and some through retrospective reviews of roentgen therapy as it was employed in protocols accenting other aspects of care. Voluminous, important radiation therapy data have been deduced through the latter retrospective kinds of analyses, but this review will be confined largely to the published results of prospective, randomized cooperative clinical trials where radiation therapy was a governing variable. Certain investigations of historical interest will also be cited together with other results that established important principles even though not so rigorous in design

    Engineers rely on physicists as well as other scientists and mathematicians to explain the world in which we live. Engineers take this knowledge of the world and use it to create the world that never was. The teaching of physics and other sciences as well as mathematics is critical to maintaining our national workforce. Science and mathematics education are inherently different, however, from engineering education. Engineering educators seek to enable students to develop the habits of mind critical for innovation. Through understanding of the engineering design process and how it differs from the scientific method, students can apply problem and project based learning to solve the challenges facing society today. In this talk, I will discuss the elements critical to a solid K-12 engineering education that integrates science and mathematics to solve challenges throughout the world.

    The application of radiation in human health, for both diagnosis and treatment of disease, is an important component of the work of the IAEA. The responsibility for the increasing technical aspects of this work is undertaken by the medical physicist. To ensure good practice in this vital area structured clinical training programmes are required to complement academic learning. This publication is intended to be a guide to the practical implementation of such a programme for radiation therapy. There is a general and growing awareness that radiation medicine is increasingly dependant on well trained medical physicists that are based in the clinical setting. However an analysis of the availability of medical physicists indicates a large shortfall of qualified and capable professionals. This is particularly evident in developing countries. While strategies to increase academic educational opportunities are critical to such countries, the need for guidance on structured clinical training was recognised by the members of the Regional Cooperative Agreement (RCA) for research, development and training related to nuclear sciences for Asia and the Pacific. Consequently a technical cooperation regional project (RAS6038) under the RCA programme was formulated to address this need in the Asia Pacific region by developing suitable material and establishing its viability. Development of a clinical training guide for medical physicists specialising in radiation therapy was started in 2005 with the appointment of a core drafting committee of regional and international experts. Since 2005 the IAEA has convened two additional consultant group meetings including additional experts to prepare the present publication.

    Despite intense efforts, the socioeconomic burden of cancer remains unacceptably high and treatment advances for many common cancers have been limited, suggesting a need for a new approach to drug development. One issue central to this lack of progress is the heterogeneity and genetic complexity of many tumours. This results in considerable variability in therapeutic response and requires knowledge of the molecular profile of the tumour to guide appropriate treatment selection for individual patients. While recent advances in the molecular characterisation of different cancer types have the potential to transform cancer treatment through precision medicine, such an approach presents a major economic challenge for drug development, since novel targeted agents may only be suitable for a small cohort of patients. Identifying the patients who would benefit from individual therapies and recruiting sufficient numbers of patients with particular cancer subtypes into clinical trials is challenging, and will require collaborative efforts from research groups and industry in order to accelerate progress. A number of molecular screening platforms have already been initiated across Europe, and it is hoped that these networks, along with future collaborations, will benefit not only patients but also society through cost reductions as a result of more efficient use of resources. This review discusses how current developments in translational oncology may be applied in clinical practice in the future, assesses current programmes for the molecular characterisation of cancer and describes possible collaborative approaches designed to maximise the benefits of translational science for patients with cancer.

  16. Physician recruitment of patients to non-therapeutic oncology clinical trials: ethics revisited

    Directory of Open Access Journals (Sweden)

    Lee eBlack

    2013-03-01

    Full Text Available Tailoring medical treatment to individual patients requires a strong foundation in research to provide the data necessary to understand the relationship between the disease, the patient, and the type of treatment advocated for. Non-therapeutic oncology clinical trials studying therapeutic resistance require the participation of patients, yet only a small percentage enroll. Treating physicians are often relied on to recruit patients, but they have a number of ethical obligations that might be perceived as barriers to recruiting. Concepts such as voluntariness of consent and conflicts of interest can have an impact on whether physicians will discuss clinical trials with their patients and how patients perceive the information. However, these ethical obligations should not be prohibitive to physician recruitment of patients—precautions can be taken to ensure that patients’ consent to research participation is fully voluntary and devoid of conflict, such as the use of other members of the research team than the treating physician to discuss the trial and obtain consent, and better communication between researchers, clinicians and patients. These can ensure that research benefits are maximized for the good of patients and society.

    Case rate payments combined with utilization monitoring may have the potential to improve the quality of care by reducing over and under-treatment. Thus, a national managed care organization introduced case rate payments at one multi-site radiation oncology provider while maintaining only fee-for-service payments at others. This study examined whether the introduction of the payment method had an effect on radiation fractions administered when compared to clinical guidelines. The number of fractions of radiation therapy delivered to patients with bone metastases, breast, lung, prostate, and skin cancer was assessed for concordance with clinical guidelines. The proportion of guideline-based care ascertained from the payer's claims database was compared before (2011) and after (2013) the payment method introduction using relative risks (RR). After the introduction of case rates, there were no significant changes in guideline-based care in breast, lung, and skin cancer; however, patients with bone metastases and prostate cancer were significantly more likely to have received guideline-based care (RR = 2.0 and 1.1, respectively, pcase rate payments, while the over-treatment rate remained steady at 9%, with no significant change (p = 0.20). These findings suggest that the introduction of case rate payments did not adversely affect the rate of guideline-based care at the provider examined. Additional research is needed to isolate the effect of the payment model and assess implications in other populations.

    Since their description and identification in leukemias and solid tumors, cancer stem cells (CSC) have been the subject of intensive research in translational oncology. Indeed, recent advances have led to the identification of CSC markers, CSC targets, and the preclinical and clinical evaluation of the CSC-eradicating (curative) potential of various drugs. However, although diverse CSC markers and targets have been identified, several questions remain, such as the origin and evolution of CSC, mechanisms underlying resistance of CSC against various targeted drugs, and the biochemical basis and function of stroma cell-CSC interactions in the so-called 'stem cell niche.' Additional aspects that have to be taken into account when considering CSC elimination as primary treatment-goal are the genomic plasticity and extensive subclone formation of CSC. Notably, various cell fractions with different combinations of molecular aberrations and varying proliferative potential may display CSC function in a given neoplasm, and the related molecular complexity of the genome in CSC subsets is considered to contribute essentially to disease evolution and acquired drug resistance. In the current article, we discuss new developments in the field of CSC research and whether these new concepts can be exploited in clinical practice in the future.

    Full Text Available Introduction. A survey was sent to referring oncologists (ROs to explore the reasons behind their referral patterns and perceptions of Phase I studies before and after being provided with outcome data from advanced colorectal cancer (ACRC patients who participated in Phase I trials at the Royal Marsden Hospital (RMH. Results. The response rate was 32/50 (64%. The most common reason for referral was exhaustion of standard treatments (31%, and the main reason for referring to the RMH was proximity to patients (28%. The most frequent clinical parameter assessed prior to referral was performance status (93%. ROs spent a median of 15 min (range: 5–45 min discussing general aspects of Phase I trials. In the second part of the questionnaire, after reviewing clinical outcome data of ACRC patients who participated in Phase I trials, 47% would change their approach, specifically, spend more time to discuss risks and benefits of Phase I trials (9%, consider prognostic factors before referral (13%, and increase the number of referrals (25%. Conclusion. This is the first report focusing on communication between ROs and a specialist Phase I unit. Outcome reporting can improve communication with ROs and importantly has the potential for better patient selection considered for Phase I oncology trials.

    The efficacy of PD-1/PD-L1 targeted therapies in addition to anti-CTLA-4 solidifies immunotherapy as a modality to add to the anticancer arsenal. Despite raising the bar of clinical efficacy, immunologically targeted agents raise new challenges to conventional drug development paradigms by highlighting the limited relevance of assessing standard pharmacokinetics (PK) and pharmacodynamics (PD). Specifically, systemic and intratumoral immune effects have not consistently correlated with standard relationships between systemic dose, toxicity, and efficacy for cytotoxic therapies. Hence, PK and PD paradigms remain inadequate to guide the selection of doses and schedules, both starting and recommended Phase 2 for immunotherapies. The promise of harnessing the immune response against cancer must also be considered in light of unique and potentially serious toxicities. Refining immune endpoints to better inform clinical trial design represents a high priority challenge. The Cancer Immunotherapy Trials Network investigators review the immunodynamic effects of specific classes of immunotherapeutic agents to focus immune assessment modalities and sites, both systemic and importantly intratumoral, which are critical to the success of the rapidly growing field of immuno-oncology.

    2014-09-10

    Nanotechnology, the manipulation of matter on atomic and molecular scales, is a relatively new branch of science. It has already made a significant impact on clinical medicine, especially in oncology. Nanomaterial has several characteristics that are ideal for oncology applications, including preferential accumulation in tumors, low distribution in normal tissues, biodistribution, pharmacokinetics, and clearance, that differ from those of small molecules. Because these properties are also well suited for applications in radiation oncology, nanomaterials have been used in many different areas of radiation oncology for imaging and treatment planning, as well as for radiosensitization to improve the therapeutic ratio. In this article, we review the unique properties of nanomaterials that are favorable for oncology applications and examine the various applications of nanotechnology in radiation oncology. We also discuss the future directions of nanotechnology within the context of radiation oncology.

    We have collected and analyzed the relevant data from public schools in greater Houston area of Texas. Based and analyzed. Since the data is only limited to a few school, we are still working on getting more data so that we can compare and contrast the results adequately and understand the core of the enrollment issue at the national level. However, based on the raw data and partial analysis, we propose a few recommendations towards the improvement of science education in Texas Schools, in general, and greater Houston area schools in particular. Our results indicate that the quality of science education can be improved significantly if we focus on the improvement of high school education or even intermediate schools when students are first time exposed to science in a little technical way. Simply organizing teacher training programs at K-12 level as school education plays a pivotal role in the decrease in physics enrollment at the higher level. Similar analysis can actually be generalized to other states to f...

  5. The script concordance test in radiation oncology: validation study of a new tool to assess clinical reasoning

    International Nuclear Information System (INIS)

    The Script Concordance test (SCT) is a reliable and valid tool to evaluate clinical reasoning in complex situations where experts' opinions may be divided. Scores reflect the degree of concordance between the performance of examinees and that of a reference panel of experienced physicians. The purpose of this study is to demonstrate SCT's usefulness in radiation oncology. A 90 items radiation oncology SCT was administered to 155 participants. Three levels of experience were tested: medical students (n = 70), radiation oncology residents (n = 38) and radiation oncologists (n = 47). Statistical tests were performed to assess reliability and to document validity. After item optimization, the test comprised 30 cases and 70 questions. Cronbach alpha was 0.90. Mean scores were 51.62 (± 8.19) for students, 71.20 (± 9.45) for residents and 76.67 (± 6.14) for radiation oncologists. The difference between the three groups was statistically significant when compared by the Kruskall-Wallis test (p < 0.001). The SCT is reliable and useful to discriminate among participants according to their level of experience in radiation oncology. It appears as a useful tool to document the progression of reasoning during residency training

    Training program IAEA TCS-37 (Training course series No.37) 'Clinical Training Specializing in Radiation Oncology (2009)' was fixed to practical training syllabus at faculty and graduate course of medical physics of a university. TCS-47 for diagnostic radiology (2010) and TCS-50 for nuclear medicine (2011) were also involved in the syllabus. These training courses had been developed by IAEA RCA RAS6038 project since 2002. In this paper, first, comparison with other training programs in the world was made in terms of (1) Degree of extent of subject or field, (2) Concreteness or specificity, (3) Degree of completion, (4) Method of certification and (5) Practicability. IAEA TCS series got the most points among ten programs such as EMERALD/EMIT, AAPM rpt. No.90 and CAMPEP accredited programs. Second, TCS-37, TCS-47 and TCS-50 were broken down to 6, 5 and 6 subjects of training course respectively. Third, each subject was further broken down to 15 times of training schedule where every time was composed by 3 hours of training. Totally 45 hours of a subject were assigned to one semester for getting one unit of credit. Seventeen units should be credited up to three years in graduate course to finish the whole program.

    In modern radiation oncology, tolerance dose-constraints for organs at risk (OAR) must be considered for treatment planning, but particularly in order to design clinical studies. Tolerance dose tables, however, only address one aspect of the therapeutic ratio of any clinical study, i.e., the limitation of adverse events, but not the desired potential improvement in the tumor effect of a novel treatment strategy. A sensible application of ''tolerance doses'' in a clinical situation requires consideration of various critical aspects addressed here: definition of tolerance dose, specification of an endpoint/symptom, consideration of radiation quality and irradiation protocol, exposed volume and dose distribution, and patient-related factors of radiosensitivity. The currently most comprehensive estimates of OAR radiation tolerance are in the QUANTEC compilations (2010). However, these tolerance dose values must only be regarded as a rough orientation and cannot answer the relevant question for the patients, i.e., if the study can achieve a therapeutic advantage; this can obviously be answered only by the final scientific analysis of the study results. Despite all limitations, the design of clinical studies should currently refer to the QUANTEC values for appreciation of the risk of complications, if needed supplemented by one's own data or further information from the literature. The implementation of a consensus on the safety interests of the patients and on an application and approval process committed to progress in medicine, with transparent quality-assuring requirements with regard to the structural safeguarding of the study activities, plays a central role in clinical research in radiation oncology.

  10. American Society of Clinical Oncology policy statement update: genetic testing for cancer susceptibility.

    Science.gov (United States)

    2003-06-15

    As the leading organization representing cancer specialists involved in patient care and clinical research, the American Society of Clinical Oncology (ASCO) reaffirms its commitment to integrating cancer risk assessment and management, including molecular analysis of cancer predisposition genes, into the practice of oncology and preventive medicine. The primary goal of this effort is to foster expanded access to, and continued advances in, medical care provided to patients and families affected by hereditary cancer syndromes. The 1996 ASCO Statement on Genetic Testing for Cancer Susceptibility set forth specific recommendations relating to clinical practice, research needs, educational opportunities, requirement for informed consent, indications for genetic testing, regulation of laboratories, and protection from discrimination, as well as access to and reimbursement for cancer genetics services. In updating this Statement, ASCO endorses the following principles: Indications for Genetic Testing: ASCO recommends that genetic testing be offered when 1) the individual has personal or family history features suggestive of a genetic cancer susceptibility condition, 2) the test can be adequately interpreted, and 3) the results will aid in diagnosis or influence the medical or surgical management of the patient or family members at hereditary risk of cancer. ASCO recommends that genetic testing only be done in the setting of pre- and post-test counseling, which should include discussion of possible risks and benefits of cancer early detection and prevention modalities. Special Issues in Testing Children for Cancer Susceptibility: ASCO recommends that the decision to offer testing to potentially affected children should take into account the availability of evidence-based risk-reduction strategies and the probability of developing a malignancy during childhood. Where risk-reduction strategies are available or cancer predominantly develops in childhood, ASCO believes that

    Full Text Available Case rate payments combined with utilization monitoring may have the potential to improve the quality of care by reducing over and under-treatment. Thus, a national managed care organization introduced case rate payments at one multi-site radiation oncology provider while maintaining only fee-for-service payments at others. This study examined whether the introduction of the payment method had an effect on radiation fractions administered when compared to clinical guidelines. The number of fractions of radiation therapy delivered to patients with bone metastases, breast, lung, prostate, and skin cancer was assessed for concordance with clinical guidelines. The proportion of guideline-based care ascertained from the payer's claims database was compared before (2011 and after (2013 the payment method introduction using relative risks (RR. After the introduction of case rates, there were no significant changes in guideline-based care in breast, lung, and skin cancer; however, patients with bone metastases and prostate cancer were significantly more likely to have received guideline-based care (RR = 2.0 and 1.1, respectively, p<0.05. For the aggregate of all cancers, the under-treatment rate significantly declined (p = 0.008 from 4% to 0% after the introduction of case rate payments, while the over-treatment rate remained steady at 9%, with no significant change (p = 0.20. These findings suggest that the introduction of case rate payments did not adversely affect the rate of guideline-based care at the provider examined. Additional research is needed to isolate the effect of the payment model and assess implications in other populations.

    Nurses today work in practice settings where the expectation is to "draw upon the best evidence to provide the care most appropriate to each patient" (Olsen, Goolsby, & McGinnis, 2009, p. 10) while caring for patients with high acuity in highly specialized settings. Within the nursing profession, the Magnet Recognition Program® advocates for exemplary professional practice and the generation of new knowledge through research and clinical innovation. Nurses working in a clinical setting are often the best resource to identify important clinical questions and gaps in practice, but a lack of resources presents challenges to nurses in fully developing their questions and identifying the most appropriate methods to answer them. These challenges often fall into three broad categories: individual nurse characteristics, organizational characteristics, and environmental characteristics (Dobbins, Ciliska, Cockerill, Barnsley, & DiCenso, 2002). Creating a dedicated partnership between nurses and library staff is one method that can overcome these challenges to use existing resources and support nurses who are asking and answering important clinical questions (DePalma, 2005; Vrabel, 2005).

    International Nuclear Information System (INIS)

    Purpose: To assess the degree to which the sociodemographic characteristics of patients enrolled in Radiation Therapy Oncology Group (RTOG) clinical trails are representative of the general population. Methods and Materials: Sociodemographic data were collected on 4016 patients entered in 33 open RTOG studies between July 1991 and June 1994. The data analyzed included educational attainment, age, gender, and race. For comparison, we obtained similar data from the U.S. Department of Census. We also compared our RTOG data with Surveillance Epidemiology and End Results (SEER) data for patients who received radiation therapy, to determine how RTOG patients compared with cancer patients in general, and with patients with cancers at sites typically treated with radiotherapy. Results: Overall, the sociodemographic characteristics of patients entered in RTOG trials were similar to those of the Census data. We found that, in every age group of African-American men and at nearly every level of educational attainment, the proportion of RTOG trial participants mirrored the proportion in the census data. Significant differences were noted only in the youngest category of African-American men, where the RTOG accrues more in the lower educational categories and fewer with college experience. For African-American women, we found a similar pattern in every age group and at each level of educational attainment. As with men, RTOG trials accrued a considerably larger proportion of younger, less educated African-American women than the census reported. Using SEER for comparison, the RTOG enrolled proportionately more African-American men to trials all cancer sites combined, and for prostate and head and neck cancer. In head and neck trials, the RTOG enrolled nearly twice as many African-American men than would be predicted by SEER data. In lung cancer trials, RTOG underrepresented African-American men significantly; however, there was no difference for brain cancer trials. There were

    2004-12-01

    Upper Peninsula Seismic Experiments in Schools (UPSeis) is an educational program developed to engage K-12 students in hands-on activities learning about earthquakes and Earth science. The system is intended to enhance teaching earth sciences to students, typically using teleseismic and regional earthquakes recorded directly in the classroom. This seismograph is computer-based and self-contained, requiring no hook-ups to the Internet or to advanced timing devices. It is easy to operate and relatively inexpensive to purchase. The UPSeis curriculum is designed so that a seismograph operates in a classroom for two or three months at a time, allowing the recording of at least 2 to 3 very large earthquakes somewhere in the world. The system comes with classroom activities, which are broken into several units, such as 'Seismic Waves', 'The UPSeis Technique' and 'Earthquake Hazards'. Within each unit, activities are rated for the appropriate grade level. All of the units have also been correlated to the Michigan Content Standards, and are easily adaptable to other state educational content standards as well. Our intention is to assist teachers and volunteers with bringing earth science into the classroom, by making it easier to obtain and operate seismographs. Ideally, a sponsor (University or Company) will pay for a system and any related costs. We further plan to train volunteers at conferences and meetings (such as AGU or SEG) in order to train them on a system and provide them with the knowledge required to assist teachers in the classroom. The volunteer would be available to come into the school and work with the teacher and students on some of the activities, particularly after they have recorded an earthquake. In addition, the volunteer would rotate their system between local area schools every 2 or 3 months. This allows teachers to use the system for a few months without the concern for maintenance of a permanent system. For schools interested in having a

    Stereotactic ablative radiotherapy is a modern cancer treatment strategy able to deliver highly focused radiation in one or a few fractions with a radical intent in several clinical settings. Young radiation oncologists need a constant and tailored update in this context to improve patient care in daily clinical practice. A recent meeting of AIRO Giovani (AIRO--Young Members Working Group) was specifically addressed to this topic, presenting state-of-the-art knowledge, based on the latest evidence in this field. Highlights of the congress are summarized and presented in this report, including thorough contributions of the speakers dealing with the role of stereotactic ablative radiotherapy in both oncological and non-oncological diseases, divided according to anatomical and clinical scenarios: intra-cranial settings (brain malignant primary tumors, metastases, benign tumors and functional disorders) and extra-cranial indications (lung primary tumors and metastases, thoracic re-irradiation, liver, lymph node and bone metastases, prostate cancer). With literature data discussed during the congress as a background, stereotactic ablative radiotherapy has proved to be a consolidated treatment approach in specific oncological and non-oncological scenarios, as well as a promising option in other clinical settings, requiring a further prospective validation in the near future. We herein present an updated overview of stereotactic ablative radiotherapy use in the clinic. PMID:25688503

    At a meeting of the Translation Research Program of the Radiation Therapy Oncology Group held in early 2008, attendees focused on updating the current state of knowledge in cancer stem cell research and discussing ways in which this knowledge can be translated into clinical use across all disease sites. This report summarizes the major topics discussed and the future directions that research should take. Major conclusions of the symposium were that the flow cytometry of multiple markers in fresh tissue would remain the standard technique of evaluating cancer-initiating cells and that surrogates need to be developed for both experimental and clinical use.

    F-18 fluorodeoxyglucose (FDG) uptake of myocardium is influenced by various factors. Increased glycolysis, and subsequent increased F-18 FDG uptake has been reported in ischemic cardiomyopathy. However, clinical significance of incidentally found myocardial F-18 FDG uptake has not been clarified. We retrospectively reviewed the degree and pattern of myocardial uptake in patients without history of ischemic heart disease who underwent torso F-18 FDG PET/CT for evaluation of neoplastic disease. From January 2005 to June 2009, 77 patients who underwent F-18 FDG PET/CT and Tc-99m sestamibi stress/rest SPECT within 3 months were enrolled. Of 77 patients, 55 (71.4%) showed increased F-18 FDG uptake in the myocardium. In this population, 40 showed uniform uptake pattern, while 15 showed focal uptake. In patients with uniform uptake, 17 showed decreased uptake in the septum without perfusion defect on myocardial SPECT. Remaining 23 patients showed uniform uptake, with 1 reversible perfusion defect and 1 fixed perfusion defect. In 15 patients with focal uptake, 9 showed increased F-18 FDG uptake in the base, and only 1 of them showed reversible perfusion defect on myocardial SPECT. In the remaining 6 focal uptake group, 4 had reversible perfusion defect in the corresponding wall, and 1 had apical hypertrophy. We demonstrated that septal defect pattern and basal uptake pattern in the myocardium may represent normal variants. Focal myocardial uptake other than normal variants on oncologic torso F-18 FDG PET/CT with routine fasting protocol may suggest ischemic heart disease, thus further evaluation is warranted.

Remaining 23 patients showed uniform uptake, with 1 reversible perfusion defect and 1 fixed perfusion defect. In 15 patients with focal uptake, 9 showed increased F-18 FDG uptake in the base, and only 1 of them showed reversible perfusion defect on myocardial SPECT. In the remaining 6 focal uptake group, 4 had reversible perfusion defect in the corresponding wall, and 1 had apical hypertrophy. We demonstrated that septal defect pattern and basal uptake pattern in the myocardium may represent normal variants. Focal myocardial uptake other than normal variants on oncologic torso F-18 FDG PET/CT with routine fasting protocol may suggest ischemic heart disease, thus further evaluation is warranted

    Streptococcus agalactiae (group B streptococcus [GBS]) colonizes the rectovaginal tract in 20% to 30% of women and during pregnancy can be transmitted to the newborn, causing severe invasive disease. Current routine screening and antibiotic prophylaxis have fallen short of complete prevention of GBS transmission, and GBS remains a leading cause of neonatal infection. We have investigated the ability of Streptococcus salivarius, a predominant member of the native human oral microbiota, to control GBS colonization. Comparison of the antibacterial activities of multiple S. salivarius strains by use of a deferred-antagonism test showed that S. salivarius strain K12 exhibited the broadest spectrum of activity against GBS. K12 effectively inhibited all GBS strains tested, including disease-implicated isolates from newborns and colonizing isolates from the vaginal tract of pregnant women. Inhibition was dependent on the presence of megaplasmid pSsal-K12, which encodes the bacteriocins salivaricin A and salivaricin B; however, in coculture experiments, GBS growth was impeded by K12 independently of the megaplasmid. We also demonstrated that K12 adheres to and invades human vaginal epithelial cells at levels comparable to GBS. Inhibitory activity of K12 was examined in vivo using a mouse model of GBS vaginal colonization. Mice colonized with GBS were treated vaginally with K12. K12 administration significantly reduced GBS vaginal colonization in comparison to nontreated controls, and this effect was partially dependent on the K12 megaplasmid. Our results suggest that K12 may have potential as a preventative therapy to control GBS vaginal colonization and thereby prevent its transmission to the neonate during pregnancy. PMID:26077762

    Adolescent and Young Adult Oncology (AYAO, including patients 15-39 years of age) is an emerging discipline in the field of cancer treatment and research. Poorer survival outcomes for this population and characteristic age-related challenges in care have called attention to the need for increased AYAO research. This chapter outlines pressing questions and reviews recent progress in AYAO research within the current organizational structure of the federal clinical trials enterprise, emphasizing how the United States National Cancer Institute's National Clinical Trials Network (NCTN) has created novel opportunities for collaborative AYAO research among the pediatric and adult NCTN groups. Potential strategies for expanding AYAO research, both within the NCTN and with other partners in the federal and advocacy domains are identified. PMID:26433555

    Purpose To assist in determining barriers to an oncology career incorporating cancer prevention, the American Society of Clinical Oncology (ASCO) Cancer Prevention Workforce Pipeline Work Group sponsored surveys of training program directors and oncology fellows. Methods Separate surveys with parallel questions were administered to training program directors at their fall 2013 retreat and to oncology fellows as part of their February 2014 in-training examination survey. Forty-seven (67%) of 70 training directors and 1,306 (80%) of 1,634 oncology fellows taking the in-training examination survey answered questions. Results Training directors estimated that ≤ 10% of fellows starting an academic career or entering private practice would have a career focus in cancer prevention. Only 15% of fellows indicated they would likely be interested in cancer prevention as a career focus, although only 12% thought prevention was unimportant relative to treatment. Top fellow-listed barriers to an academic career were difficulty in obtaining funding and lower compensation. Additional barriers to an academic career with a prevention focus included unclear career model, lack of clinical mentors, lack of clinical training opportunities, and concerns about reimbursement. Conclusion Reluctance to incorporate cancer prevention into an oncology career seems to stem from lack of mentors and exposure during training, unclear career path, and uncertainty regarding reimbursement. Suggested approaches to begin to remedy this problem include: 1) more ASCO-led and other prevention educational resources for fellows, training directors, and practicing oncologists; 2) an increase in funded training and clinical research opportunities, including reintroduction of the R25T award; 3) an increase in the prevention content of accrediting examinations for clinical oncologists; and 4) interaction with policymakers to broaden the scope and depth of reimbursement for prevention counseling and

    For decades Western medicine has followed a biomedical model based on linear thinking and an individualized, disease-oriented doctor-patient relationship. Today this framework must be replaced by a biopsychosocial model based on complexity theory and a person-oriented medical team-patient relationship, taking into account the psychological and social determinants of health and disease. However, the new model is already proving no longer adequate or appropriate, and current events are urging us to develop an ecological model in which the medical team takes into account both individual illness and population health as a whole, since we are all part of the biosphere. In recent years, the rising costs of cancer treatment have raised a serious issue of economic sustainability. As the population of our planet, we now need to rapidly address this issue, and everyone of us must try to reduce their ecological footprint, measured as CO2 production. Medical oncologists need to reduce the ecological footprint of their professional activity by lowering the consumption of economic resources and avoiding environmental damage as much as possible. This new paradigm is endorsed by the Italian College of Hospital Medical Oncology Directors (CIPOMO). A working group of this organization has drafted the "Green Oncology Position Paper": a proposal of Italian medical oncology (in accordance with international guidelines) that oncologists, while aiming for the same end results, make a commitment toward the more appropriate management of health care and the careful use of resources in order to protect the environment and the ecosphere during the daily exercise of their professional activities.

    The purposes of this study, in oncology outpatients receiving chemotherapy (n = 926), were to: describe the occurrence of different types of pain (ie, no pain, only noncancer pain [NCP], only cancer pain [CP], or both CP and NCP) and evaluate for differences in demographic, clinical, and symptom characteristics, and quality of life (QOL) among the 4 groups. Patients completed self-report questionnaires on demographic and symptom characteristics and QOL. Patients who had pain were asked to indicate if it was or was not related to their cancer or its treatment. Medical records were reviewed for information on cancer and its treatments. In this study, 72.5% of the patients reported pain. Of the 671 who reported pain, 21.5% reported only NCP, 37.0% only CP, and 41.5% both CP and NCP. Across the 3 pain groups, worst pain scores were in the moderate to severe range. Compared with the no pain group, patients with both CP and NCP were significantly younger, more likely to be female, have a higher level of comorbidity, and a poorer functional status. In addition, these patients reported: higher levels of depression, anxiety, fatigue, and sleep disturbance; lower levels of energy and attentional function; and poorer QOL. Patients with only NCP were significantly older than the other 3 groups. The most common comorbidities in the NCP group were back pain, hypertension, osteoarthritis, and depression. Unrelieved CP and NCP continue to be significant problems. Oncology outpatients need to be assessed for both CP and NCP conditions.

    Background and objectives Relevant heterogeneity exists among Postgraduate Schools in Medical Oncology, also within the same country. In order to provide a comprehensive overview of the landscape of Italian Postgraduate Schools in Medical Oncology, the Italian Association of Medical Oncology (AIOM) undertook an online survey, inviting all the residents to describe their daily activities and to express their overall satisfaction about their programs. Methods A team composed of five residents and three consultants in medical oncology prepared a 38 items questionnaire that was published online in a reserved section, accessible through a link sent by e-mail. Residents were invited to anonymously fill in the questionnaire that included the following sub-sections: quality of teaching, clinical and research activity, overall satisfaction. Results Three-hundred and eleven (57%) out of 547 invited residents filled in the questionnaire. Two-hundred and twenty-three (72%) participants declared that attending lessons was frequently difficult and 153 (49%) declared they did not gain substantial improvement in their knowledge from them. Fifty-five percent stated that they did not receive lessons on palliative care. Their overall judgment about didactic activity was low in 63% of the interviewed. The satisfaction for clinical activity was in 86% of cases good: 84% recognized that, during the training period, they acquired a progressive independence on patients' management. About research activity, the majority (79%) of participants in the survey was actively engaged in managing patients included in clinical trials but the satisfaction level for the involvement in research activities was quite low (54%). Overall, 246 residents (79%) gave a positive global judgment of their Medical Oncology Schools. Conclusions The landscape of Italian Postgraduate Schools in Medical Oncology is quite heterogeneous across the country. Some improvements in the organization of teaching and in the

    Infectious diseases are important causes of morbidity and mortality in patients with cancer. The NCCN Clinical Practice Guidelines in Oncology (NCCN Guidelines) for Prevention and Treatment of Cancer-Related Infections characterize the major pathogens to which patients with cancer are susceptible, with a focus on the prevention, diagnosis, and treatment of major common and opportunistic infections. This portion of the guidelines highlights the sections on antifungal and antiviral prophylaxis. Antifungal and antiviral prophylaxis recommendations have expanded over the past few years. New agents for the treatment of fungal infections and incorporation of therapeutic drug monitoring are presented. Antiviral prophylaxis for hepatitis B and management considerations for hepatitis C and HIV have been further developed.

  1. Routine administration of standardized questionnaires that assess aspects of patients quality of life in medical oncology clinics: A systematic review

    International Nuclear Information System (INIS)

    Purpose: Increasing interest in the Quality of Life outcomes in cancer patients led to increase implementation of their use in routine clinical practice. The aim of this systemic review is to review the scientific evidence behind recommending the use of quality of life (QoL) scales routinely in outpatient evaluation. Methods: Systematic review for all published randomized controlled trials in English language between January 1, 1990 till December 31, 2012. Out of 487 articles (476 identified by electronic search + 11 articles identified by manual search), six trials satisfied the eligibility criteria: (1) the study was a randomized controlled trial (RCT) with randomization of patients or health care providers; (2) the findings of the administered questionnaire or scale (the intervention) were given to health care provider, and compared to standard care with no questionnaire administered (the control); (3) study was conducted in outpatient oncology clinics; and (4) an outcome was measured that related to (i) QoL improvement, (ii) reduction in morbidity, (iii) reduction in stress for the patients, (iv) improvement in communication between patients and health care provider, or (v) improved patient satisfaction. Assessment for the quality of the study was done using the GRADE methodology. Results: Serious methodological issues were affecting most of the trials. Overall the evaluation of the quality of the evidence from these identified trials suggests that there is a weak recommendation to use QoL scales in routine oncology practice to improve communication between physicians and patients. Conclusion: The routine use of such tools in the outpatient settings at improving the patient outcome or satisfaction cannot be recommended based on the available evidence. The potential harm with the excess use of resources needed to implement, collect, store, analyse, and present such data to health care providers should be also considered.

    Follow-up of operable breast cancer patients takes up a significant proportion of British oncologists' time, with 90% seeing 5-50 patients each week. Procedures vary greatly, but, in patients treated by surgery and radiotherapy, care is usually shared, with alternating visits to see each team. Currently, the general practitioner has sole responsibility for follow-up in less than 3% of patients. They tend to be followed up in general, rather than specialist, clinics. There is almost universal agreement that routine blood tests, radiographs and scans are not indicated as part of routine follow-up, but the role of mammography in evaluating an irradiated breast remains a source of debate. Just over a half of the oncologists surveyed order baseline mammography of both treated and contralateral breasts, usually between 6 and 12 months after local excision and radiotherapy, with further follow-up 1-3-yearly thereafter. Ten per cent of the participating oncologists never suggest follow-up mammography. Patients tend to be followed in oncology clinics at 3-4-monthly intervals for the first 2 years, 6-monthly in the third and fourth years and, thereafter, yearly. Fifteen per cent of oncologists discharge patients at 5 years, with the discharge rate rising to 43% at 10 years; around one-third modify follow-up according to the age of the patient. The aims of follow-up were seen to include detection of curable disease, but other goals were perceived as equally important (e.g. detection of iatrogenic problems, audit, counselling, education and the provision of early palliation of incurable and metastatic disease. Breast cancer is no longer seen as an absolute contraindication to either pregnancy or the use of hormone replacement therapy (HRT); however, oncologists are uncertain about the appropriate use of HRT, either alone or with tamoxifen. This audit highlights a number of research areas: the identification of the appropriate site and skill-mix for follow-up of patients

    Neuroimaging research often relies on clinically acquired magnetic resonance imaging (MRI) datasets that can originate from multiple institutions. Such datasets are characterized by high heterogeneity of modalities and variability of sequence parameters. This heterogeneity complicates the automation of image processing tasks such as spatial co-registration and physiological or functional image analysis. Given this heterogeneity, conventional processing workflows developed for research purposes are not optimal for clinical data. In this work, we describe an approach called Heterogeneous Optimization Framework (HOF) for developing image analysis pipelines that can handle the high degree of clinical data non-uniformity. HOF provides a set of guidelines for configuration, algorithm development, deployment, interpretation of results and quality control for such pipelines. At each step, we illustrate the HOF approach using the implementation of an automated pipeline for Multimodal Glioma Analysis (MGA) as an example. The MGA pipeline computes tissue diffusion characteristics of diffusion tensor imaging (DTI) acquisitions, hemodynamic characteristics using a perfusion model of susceptibility contrast (DSC) MRI, and spatial cross-modal co-registration of available anatomical, physiological and derived patient images. Developing MGA within HOF enabled the processing of neuro-oncology MR imaging studies to be fully automated. MGA has been successfully used to analyze over 160 clinical tumor studies to date within several research projects. Introduction of the MGA pipeline improved image processing throughput and, most importantly, effectively produced co-registered datasets that were suitable for advanced analysis despite high heterogeneity in acquisition protocols.

    The relationship of valine resistance to the expression of the ilvGEDA operon of Escherichia coli K-12 has been determined. DNA sequence and in vivo protein analyses indicate that in wild-type E. coli K-12 there is a frameshift site within the gene (ilvG) for valine resistance. The ilvG+2096 (formerly designated ilv02096) mutation displaces this frameshift site, resulting in the expression of ilvG and the relief of transcriptional polarity on the distal genes of this operon. Thus, the "ilv0" ...

  5. Instruction in medical ethics during clinical training for medical students. Report on experience in radio-oncology

    International Nuclear Information System (INIS)

    The article gives a review of the current state of education in medical ethics in Germany. The issue is considered from the viewpoint of radio-oncology. Both the pertinent literature and our own experience in teaching medical ethics are presented. In October 2003, medical ethics was integrated into the curriculum of medicine. The aim was to train competence in the field of personal attitudes and to intensify skills of moral reasoning. Our own experiences are positive, which is in accordance with the reports of other working groups. Most of the students were interested in education in medical ethics and looked upon ethical training as being an important part of their studies. Medical students are interested in ethical education during the clinical period of their studies, which has been taken into account since the actual change of the curriculum. Radio-oncologists as specialists in other clinical fields can offer important contributions when they discuss clinical cases from the viewpoint of medical ethics. The long-term effect of such an education will become the subject of future research. (orig.)

    Treating patients with novel biological agents is becoming a leading trend in oncology. Unlike cytotoxic agents, for which efficacy and toxicity monotonically increase with dose, biological agents may exhibit non-monotonic patterns in their dose-response relationships. Using a trial with two biological agents as an example, we propose a dose-finding design to identify the biologically optimal dose combination (BODC), which is defined as the dose combination of the two agents with the highest efficacy and tolerable toxicity. A change-point model is used to reflect the fact that the dose-toxicity surface of the combinational agents may plateau at higher dose levels, and a flexible logistic model is proposed to accommodate the possible non-monotonic pattern for the dose-efficacy relationship. During the trial, we continuously update the posterior estimates of toxicity and efficacy and assign patients to the most appropriate dose combination. We propose a novel dose-finding algorithm to encourage sufficient exploration of untried dose combinations in the two-dimensional space. Extensive simulation studies show that the proposed design has desirable operating characteristics in identifying the BODC under various patterns of dose-toxicity and dose-efficacy relationships.

    Full Text Available This study seeks to understand how to use formal learning activities to effectively support the development of open education literacies among K-12 teachers. Considering pre- and post-surveys from K-12 teachers (n = 80 who participated in a three-day institute, this study considers whether participants entered institutes with false confidence or misconceptions related to open education, whether participant knowledge grew as a result of participation, whether takeaways matched expectations, whether time teaching (i.e., teacher veterancy impacted participant data, and what specific evaluation items influenced participants’ overall evaluations of the institutes. Results indicated that 1 participants entered the institutes with misconceptions or false confidence in several areas (e.g., copyright, fair use, 2 the institute was effective for helping to improve participant knowledge in open education areas, 3 takeaways did not match expectations, 4 time teaching did not influence participant evaluations, expectations, or knowledge, and 5 three specific evaluation items significantly influenced overall evaluations of the institute: learning activities, instructor, and website / online resources. Researchers conclude that this type of approach is valuable for improving K-12 teacher open education literacies, that various misconceptions must be overcome to support large-scale development of open education literacies in K-12, and that open education advocates should recognize that all teachers, irrespective of time teaching, want to innovate, utilize open resources, and share in an open manner.

    Application of ionizing radiation for the purpose of medical research in Germany needs to be approved by the national authority for radiation protection (Bundesamt fuer Strahlenschutz, BfS). For studies in the field of radiation oncology, differentiation between use of radiation for ''medical care (Heilkunde)'' versus ''medical research'' frequently leads to contradictions. The aim of this article is to provide principle investigators, individuals, and institutions involved in the process, as well as institutional review or ethics committees, with the necessary information for this assessment. Information on the legal frame and the approval procedures are also provided. A workshop was co-organized by the German Society for Radiation Oncology (DEGRO), the Working Party for Radiation Oncology (ARO) of the German Cancer Society (DKG), the German Society for Medical Physics (DGMP), and the German Cancer Consortium (DKTK) in October 2013. This paper summarizes the results of the workshop and the follow-up discussions between the organizers and the BfS. Differentiating between ''Heilkunde'' which does not need to be approved by the BfS and ''medical research'' is whether the specific application of radiation (beam quality, dose, schedule, target volume, etc.) is a clinically established and recognized procedure. This must be answered by the qualified physician(s) (''fachkundiger Arzt'' according to German radiation protection law) in charge of the study and the treatments of the patients within the study, taking into consideration of the best available evidence from clinical studies, guidelines and consensus papers. Among the important parameters for assessment are indication, total dose, and fractionation. Radiation treatments applied outside clinical trials do not require approval by the BfS, even if they are applied within a randomized or nonrandomized clinical trial

    Lindbo, David L.; Loynachan, Tom; Mblia, Monday; Robinson, Clay; Chapman, Susan

    2013-04-01

    The Soil Science Society of America created its K12 Committee in 2006 in part to compliment the Dig It! The Secrets of Soil exhibit that opened in July 2008 at the Smithsonian's Institution's Nation Museum of Natural History (of which SSS was a founding sponsor). The committee's work began quickly with a website designed to provide resources for K12 teachers. The first accomplishments included reviewing and posting links to web based information already available to teachers. These links were sorted by subject and grade level to make it easier for teachers to navigate the web and find what they needed quickly. Several presentations and lessons designed for K12 teachers were also posted at this time. Concurrent with this effort a subcommittee review and organized the national teaching standards to show where soils could fit into the overall K12 curriculum. As the website was being developed another subcommittee developed a soils book (Soil! Get the Inside Scoop, 2008) to further compliment the Dig It! exhibit. This was a new endeavor for SSSA having never worked with the non-academic audience in developing a book. Peer-reviews of this book included not only scientist but also students in order to make sure the book was attractive to them. Once the book was published and the website developed it became clear more outreach was needed. SSSA K12 Committee has attended both the National Science Teachers Association (since 2008) the USA Science and Engineering Festival (since 2010) with exhibits and workshops. It has cooperated and contributed to the American Geologic Institutes' Earth Science Week materials with brochures and lesson plans and with National Association of Conservation Districts by providing peer-review and distribution of materials. The most recent developments from the committee include a web redesign that is more student and teacher friendly, the development of a peer-review system to publish K12 Lesson Plans, and finally the publication of a new soils

    A simulation-based technical feasibility study was completed to show the types of technologies required to achieve ZEB status with this building type. These technologies are prioritized across the building's subsystem such that design teams can readily integrate the ideas. Energy use intensity (EUI) targets were established for U.S. climate zones such that K-12 schools can be zero-ready or can procure solar panels or other renewable energy production sources to meet the zero energy building definition. Results showed that it is possible for K-12 schools to achieve zero energy when the EUI is between 20 and 26 kBtu/ft2/yr. Temperate climates required a smaller percentage of solar panel coverage than very hot or very cold climates. The paper provides a foundation for technically achieving zero energy schools with a vision of transforming the school construction market to mainstream zero energy buildings within typical construction budgets.

    Analyzing the molecular interplay between malignancies and therapeutic agents is rarely a straightforward process, but we hope that this special issue of Seminars has highlighted the clinical value of such endeavors as well as the relevant theoretical and practical considerations. Here, we conclude with both an overview of the various high-value applications of clinical pharmacodynamics (PD) in developmental therapeutics and an outline of the framework for incorporating PD analyses into the design of clinical trials. Given the increasingly recognized importance of determining and administering the biologically effective dose (BED) and schedule of targeted agents, we explain how clinical PD biomarkers specific to the agent mechanism of action (MOA) can be used for the development of pharmacodynamics-guided biologically effective dosage regimens (PD-BEDR) to maximize the efficacy and minimize the toxicity of targeted therapies. In addition, we discuss how MOA-based PD biomarker analyses can be used both as patient selection diagnostic tools and for designing novel drug combinations targeting the specific mutational signature of a given malignancy. We also describe the role of PD analyses in clinical trials, including for MOA confirmation and dosage regimen optimization during phase 0 trials as well as for correlating molecular changes with clinical efficacy when establishing proof-of-concept in phase I/II trials. Finally, we outline the critical technological developments that are needed to enhance the quality and quantity of future clinical PD data collection, broaden the types of molecular questions that can be answered in the clinic, and, ultimately, improve patient outcomes.

    2002-09-01

    Full Text Available The Free State and Northern Cape make up some 40% of the land area of South Africa, while being home to only 10% of the total population. Haematology and Oncotherapy outreach clinics were established in Kimberley, Bethlehem and Welkom to provide a more accessible service to the thinly spread population. A previous study showed these clinics to be cost-effective, but we had no idea how the patients experience them. Our aim was to obtain information about the demographics of the patients, the logistical support of the clinics, the medical needs of the patients and how they experience the clinics. This can help us to improve the service. A questionnaire was tested in a pilot study. The demographic questions covered age, sex and ethnicity. The logistical questions dealt with distance travelled to the clinic, mode of transport, length of time as a patient and cost. The medical need questions dealt with type of disease, treatment received, type of doctor seen and origin of referral. The questions about experience covered satisfaction with the service, staff, waiting times and involvement of non-governmental organizations. Of the 95 patients interviewed 42% were from the haematology clinics. The mean age was 59.5 and the male: female ratio was 0.6:1. Forty-six percent of the patients spoke Afrikaans and 31 % spoke South Sotho. The black:white ratio was 1:1. Twenty-eight percent used the government ambulances (of whom 80% were satisfied and 56% used their own cars. The median payment at a clinic was R20 (R0 to R200. Only 19% of patients were paying privately. Ninety-five percent of the patients were follow-ups, with the median length of follow-up being 24 months (1 to 468. The patients were mainly referred by local hospitals. Twentytwo percent of the patients had chronic haematological malignancies, while 68% had solid tumours. Thirty-seven percent of the patients received drugs to take home and only 6% got intravenous chemotherapy. Consultants saw 44

  14. Early Benefit Assessments in Oncology in Germany: How Can a Clinically Relevant Endpoint Not Be Relevant to Patients?

    Science.gov (United States)

    Ruof, Jörg; Flückiger, Olivier; Andre, Niko

    2015-09-01

    After 4 years of early benefit assessment (EBA) in Germany, it is becoming evident that the Federal Joint Committee (FJC) frequently considers well-established clinical endpoints as not being relevant to patients. Focusing on assessments of oncology medicines, we analysed the FJC's view on primary endpoints and compared it with the approach used by regulatory authorities. Mortality data were accepted by both stakeholders. Whereas regulatory authorities accepted primary morbidity endpoints such as progression-free survival and response rates, the FJC mostly excluded these from its assessments. Health-related quality of life (HRQoL) data have been poorly reflected in the approval process; for EBAs, those data have rarely impacted on benefit ratings. We argue that agreement between regulatory authorities and the FJC is required regarding primary study endpoints that are relevant to patients, and that clarification of acceptable endpoints by the FJC, especially in the morbidity domain, has to be provided. Moreover, in order to fully acknowledge the benefit of a new medicinal product, mortality, morbidity and HRQoL should be weighted differentially, according to the condition. PMID:26286202

    Bertram, K. B.

    2011-12-01

    The Science Teacher Education Program (STEP) offered a unique framework for creating professional development courses focused on Arctic research from 2006-2009. Under the STEP framework, science, technology, engineering, and math (STEM) training was delivered by teams of practicing Arctic researchers in partnership with master teachers with 20+ years experience teaching STEM content in K-12 classrooms. Courses based on the framework were offered to educators across Alaska. STEP offered in-person summer-intensive institutes and follow-on audio-conferenced field-test courses during the academic year, supplemented by online scientist mentorship for teachers. During STEP courses, teams of scientists offered in-depth STEM content instruction at the graduate level for teachers of all grade levels. STEP graduate-level training culminated in the translation of information and data learned from Arctic scientists into standard-aligned lessons designed for immediate use in K-12 classrooms. This presentation will focus on research that explored the question: To what degree was scientist involvement beneficial to teacher training and to what degree was STEP scientist involvement beneficial to scientist instructors? Data sources reveal consistently high levels of ongoing (4 year) scientist and teacher participation; high STEM content learning outcomes for teachers; high STEM content learning outcomes for students; high ratings of STEP courses by scientists and teachers; and a discussion of the reasons scientists indicate they benefited from STEP involvement. Analyses of open-ended comments by teachers and scientists support and clarify these findings. A grounded theory approach was used to analyze teacher and scientist qualitative feedback. Comments were coded and patterns analyzed in three databases. The vast majority of teacher open-ended comments indicate that STEP involvement improved K-12 STEM classroom instruction, and the vast majority of scientist open-ended comments

    Considers in detail all aspects of molecular imaging in oncology, ranging from basic research to clinical applications in the era of evidence-based medicine. Examines technological issues and probe design. Discusses preclinical studies in detail, with particular attention to multimodality imaging. Presents current clinical use of PET/CT, SPECT/CT, and optical imagingWritten by acknowledged experts. The impact of molecular imaging on diagnostics, therapy, and follow-up in oncology is increasing significantly. The process of molecular imaging includes key biotarget identification, design of specific molecular imaging probes, and their preclinical evaluation, e.g., in vivo using small animal studies. A multitude of such innovative molecular imaging probes have already entered clinical diagnostics in oncology. There is no doubt that in future the emphasis will be on multimodality imaging in which morphological, functional, and molecular imaging techniques are combined in a single clinical investigation that will optimize diagnostic processes. This handbook addresses all aspects of molecular imaging in oncology, ranging from basic research to clinical applications in the era of evidence-based medicine. The first section is devoted to technology and probe design, and examines a variety of PET and SPECT tracers as well as multimodality probes. Preclinical studies are then discussed in detail, with particular attention to multimodality imaging. In the third section, diverse clinical applications are presented, and the book closes by looking at future challenges. This handbook will be of value to all who are interested in the revolution in diagnostic oncology that is being brought about by molecular imaging.

    2006-01-01

    The development of software in radiation oncology departments has seen the increase in capability from the Record and Verify software focused on patient safety to a fully-fledged Oncology Information System (OIS). This paper reports on the medical aspects of the implementation of a modern Oncology Information System (IMPAC MultiAccess, also known as the Siemens LANTIS) in a New Zealand hospital oncology department. The department was successful in translating paper procedures into electronic procedures, and the report focuses on the changes in approach to organisation and data use that occurred. The difficulties that were faced, which included procedural re-design, management of change, removal of paper, implementation cost, integration with the HIS, quality assurance and datasets, are highlighted along with the local solutions developed to overcome these problems.

  19. Implementation of Remote 3-Dimensional Image Guided Radiation Therapy Quality Assurance for Radiation Therapy Oncology Group Clinical Trials

    International Nuclear Information System (INIS)

    Purpose: To report the process and initial experience of remote credentialing of three-dimensional (3D) image guided radiation therapy (IGRT) as part of the quality assurance (QA) of submitted data for Radiation Therapy Oncology Group (RTOG) clinical trials; and to identify major issues resulting from this process and analyze the review results on patient positioning shifts. Methods and Materials: Image guided radiation therapy datasets including in-room positioning CT scans and daily shifts applied were submitted through the Image Guided Therapy QA Center from institutions for the IGRT credentialing process, as required by various RTOG trials. A centralized virtual environment is established at the RTOG Core Laboratory, containing analysis tools and database infrastructure for remote review by the Physics Principal Investigators of each protocol. The appropriateness of IGRT technique and volumetric image registration accuracy were evaluated. Registration accuracy was verified by repeat registration with a third-party registration software system. With the accumulated review results, registration differences between those obtained by the Physics Principal Investigators and from the institutions were analyzed for different imaging sites, shift directions, and imaging modalities. Results: The remote review process was successfully carried out for 87 3D cases (out of 137 total cases, including 2-dimensional and 3D) during 2010. Frequent errors in submitted IGRT data and challenges in the review of image registration for some special cases were identified. Workarounds for these issues were developed. The average differences of registration results between reviewers and institutions ranged between 2 mm and 3 mm. Large discrepancies in the superior-inferior direction were found for megavoltage CT cases, owing to low spatial resolution in this direction for most megavoltage CT cases. Conclusion: This first experience indicated that remote review for 3D IGRT as part of QA

    Mammalian target of rapamycin (mTOR) is a PI3K-related kinase that regulates cell growth, proliferation, and survival via mTOR complex 1 (mTORC1) and mTORC2. The mTOR pathway is often aberrantly activated in cancers. While hypoxia, nutrient deprivation, and DNA damage restrain mTORC1 activity, multiple genetic events constitutively activate mTOR in cancers. Here we provide a brief overview of the signaling pathways up- and downstream of mTORC1 and -2, and discuss the insights into therapeutic anticancer targets - both those that have been tried in the clinic with limited success and those currently under clinical development - that knowledge of these pathways gives us.

  1. Clinical trial designs for evaluating the medical utility of prognostic and predictive biomarkers in oncology

    Physicians need improved tools for selecting treatments for individual patients. Many diagnostic entities hat were traditionally viewed as individual diseases are heterogeneous in their molecular pathogenesis and treatment responsiveness. This results in the treatment of many patients with ineffective drugs, incursion of substantial medical costs for the treatment of patients who do not benefit and the conducting of large clinical trials to identify small, average treatment benefits for heter...

  2. Breast-conserving therapy as a model for creating new knowledge in clinical oncology

    International Nuclear Information System (INIS)

    New knowledge can be derived from various kinds of studies. Studies of innovative approaches are the basis for progress. Some advances in treatment are so obvious that they do not need formal testing; e.g., penicillin for pneumococcal infection. For comparing interventions with small differences in efficacy or in groups without predictable outcome, prospective randomized trials are the 'gold standard'. However, randomized trials are cumbersome, expensive, and potentially difficult for both patients and physicians. Retrospective studies are less valid scientifically because they are more likely to suffer from bias, misclassification, confounding variables, and the use of multiple comparisons. Retrospective studies can be made more valid by first specifying the study design and analysis, but are generally most useful to generate hypotheses to be tested more formally. Retrospective studies can be particularly useful in improving outcome by identifying 'problems' and their causes. An important issue for radiation oncologists in doing retrospective studies is the difficulty of assessing an effect on local tumor control in diseases in which there are competing risks of local and distant failure. Many of these points will be illustrated in studies from the Joint Center for Radiation Therapy. Studies of innovative approaches, retrospective reviews and prospective randomized clinical trials have all been useful in establishing breast-conserving therapy as a safe and effective treatment for patients with early-stage breast cancer. Several studies of innovative breast-conserving therapy beginning in the 1960's showed favorable results. Based on this experience, a series of randomized clinical trials were initiated, beginning in the early 1970's, formally comparing mastectomy and breast-conserving therapy. These trials firmly established that the two forms of local treatment provide equivalent survival. Additional retrospective studies have also been useful in establishing

    Clinical trials are essential for the improvement of cancer care. The complexity of modern cancer care and research require careful design, for which input from all disciplines is necessary. Pathologists should play a key role in the design and execution of modern cancer trials, with special attention to the eligibility, stratification and evaluation of response to therapy. In the current review all these aspects are discussed, with examples from colorectal cancer trials. We describe critical issues in biomarker evaluation and development and emphasize the importance of the role of the pathologist in quality control of cancer treatment.

    K-12 educators need effective and relevant astronomy professional development. WISE Telescope (Wide-Field Infrared Survey Explorer) and Spitzer Space Telescope Education programs provided an immersive teacher professional development workshop at Arecibo Observatory in Puerto Rico during the summer of 2009. As many common misconceptions involve scale and distance, teachers worked with Moon/Earth scale, solar system scale, and distance of objects in the universe. Teachers built and used basic telescopes, learned about the history of telescopes, explored ground and satellite based telescopes, and explored and worked on models of WISE Telescope. An in-depth explanation of WISE and Spitzer telescopes gave participants background knowledge for infrared astronomy observations. We taught the electromagnetic spectrum through interactive stations. The stations included an overview via lecture and power point, the use of ultraviolet beads to determine ultraviolet exposure, the study of WISE lenticulars and diagramming of infrared data, listening to light by using speakers hooked up to photoreceptor cells, looking at visible light through diffraction glasses and diagramming the data, protocols for using astronomy based research in the classroom, and infrared thermometers to compare environmental conditions around the observatory. An overview of LIDAR physics was followed up by a simulated LIDAR mapping of the topography of Mars. We will outline specific steps for K-12 infrared astronomy professional development, provide data demonstrating the impact of the above professional development on educator understanding and classroom use, and detail future plans for additional K-12 professional development. Funding was provided by WISE Telescope, Spitzer Space Telescope, Starbucks, Arecibo Observatory, the American Institute of Aeronautics and Astronautics, and the Washington Space Grant Consortium.

  5. What is the Asian Consensus Statement on NCCN clinical practice guidelines in oncology (NCCN-ACS)?

    2016-04-01

    Cancer treatment guidelines are compiled on the basis of established evidence. Such evidence is obtained from epidemiological, pathological and pharmacological study and, most importantly of all, the information gained from clinical trials. However, very little of the kind of evidence that is required for the compilation of treatment guidelines is actually obtained from Asian countries. When one considers the ethnic differences and disparities in medical care, coupled with the tremendous cultural diversity that characterize the Asian region, it would be difficult to conclude that there is currently sufficient evidence that could form the basis for the formulation of guidelines that would be relevant and applicable to all Asian countries. An urgent issue that needs to be addressed in order to achieve a breakthrough in this difficult situation is to build up a body of evidence at an advanced level that is specific to the Asian region and Asian ethnicities. For the interim, however, it is also necessary to efficiently incorporate evidence that has been obtained in Western countries. Furthermore, an effective method of utilizing guidelines that have already been compiled in Western countries is considered to be not by simply translating them into local languages, but rather to engage in a process of adaptation, whereby the guidelines are adjusted or modified to match the circumstances of a particular country or region. The NCCN Clinical Practice Guidelines-Asian Consensus Statement (NCCN-ACS) documents have been compiled with this intention in mind, utilizing the NCCN guidelines that are widely used internationally.

    Full Text Available Abstract Pediatric communication directly contributes to treatment adherence, fewer symptoms, better clinical responses, healthier treatment adaptation and management of psychosocial issues. This study aimed to evaluate associations between the clinical and sociodemographic data of caregivers and children and the communicative patterns of pediatricians. Three oncohematology physicians and 44 child-caregiver dyads took part, with audio recording of 146 medical consultations. The physicians interacted more often with older children, offering more guidance, clarifying doubts, and asking for information. The number of questions from children and caregivers was positively correlated with the physician’s communicative behaviors. However, there was no association between the age of the children and the number of doubts of the patients. The diagnosis, treatment time, family income, marital status and caregiver’s level of education were associated with the amount of interaction provided by physicians to the children and caregivers. This study offers subsides relevant to psychosocial interventions that may improve communication in pediatric oncohematology settings.

  9. Clinical usefulness of 99mTc-EDDA/HYNIC-TOC scintigraphy in oncological diagnostics: a preliminary communication

    International Nuclear Information System (INIS)

    This study assessed the clinical usefulness of a new technetium-99m labelled somatostatin analogue from the standpoint of oncological diagnostics. The study group comprised 40 patients in whom malignant neoplasms (32 primary and 8 metastatic) had been diagnosed. Among the primary tumours there were 21 cases of lung cancer (2 small cell and 19 non-small cell), seven pituitary adenomas (five hormonally active and two inactive), one liposarcoma, two carcinoids and one breast carcinoma. The metastatic tumours consisted of three malignant melanomas, one phaeochromocytoma, one prostatic cancer, one leiomyosarcoma, one pancreatic carcinoma ectopically secreting ACTH and one carcinoid of the thymus. The radiopharmaceutical 99mTc-EDDA/HYNIC-Tyr3-octreotide was administered i.v. at an activity of 740-925 MBq. The imaging comprised a whole-body scan and a single-photon emission tomography acquisition. Positive scintigrams were obtained in all cases of small cell and non-small cell lung cancer, four out of five hormonally active pituitary adenomas, one out of two cases of carcinoid, the liposarcoma and the breast cancer. Neoplastic metastases were visualised in two out of three patients with melanoma and in patients with phaeochromocytoma, ACTH-secreting pancreatic carcinoma and thymic carcinoid. Scintigrams were negative in both hormonally inactive pituitary adenomas, in one case of metastatic malignant melanoma, in the leiomyosarcoma and in the case of metastasis from prostatic carcinoma. The results of this pilot study indicate that 99mTc-EDDA/HYNIC-TOC is a potentially useful radiopharmaceutical for imaging of a wide range of primary and metastatic tumours. Special attention should be paid to the successful imaging of all cases of non-small cell lung cancer. (orig.)

    The main objective of this research is to examine child cancer cases in Zonguldak/Turkey descriptively in epidemiological aspect with the help of GIS. Universe of the study is composed of 60 children between 1 and 19 years old who were treated in Children Oncology Clinic with a diagnosis of cancer. Whole universe was reached without selecting a sample in the study. Data were collected by using a form prepared by obtaining expert advice and they were applied to children and their parents at study dates. Results were expressed as percentages. Chi-Square test was used in intergroup comparisons, results were assessed within 95 % confidence interval and p < 0.05 was considered as statistically significant. Variables that were used in the study were assessed, recorded in prepared data collection form and distribution maps were produced. When disease diagnosis of the children participated in the study were evaluated, the most observed three types are ALL with 33.3 % (n = 20), Medullablastoma with 13.3 % (n = 8) and Hodgkin-nonHodgkin Lymphoma with 11.7 % (n = 7). Kdz. Eregli with 31.7 % (n = 19), Center with 31.7 % (n = 19), and Caycuma with 18.3 % (n = 11) are the first-three counties where the cases were mostly observed. Statistically significant difference was found (p = 0.016) comparing disease diagnosis with living place, and distribution maps of the number of cancer cases were produced.

    2008-01-10

    A MESSAGE FROM ASCO'S PRESIDENT: For the third year, the American Society of Clinical Oncology (ASCO) is publishing Clinical Cancer Advances: Major Research Advances in Cancer Treatment, Prevention, and Screening, an annual review of the most significant cancer research presented or published over the past year. ASCO publishes this report to demonstrate the important progress being made on the front lines of clinical cancer research today. The report is intended to give all those with an interest in cancer care-the general public, cancer patients and organizations, policymakers, oncologists, and other medical professionals-an accessible summary of the year's most important cancer research advances. These pages report on the use of magnetic resonance imaging for breast cancer screening, the association between hormone replacement therapy and breast cancer incidence, the link between human papillomavirus and head and neck cancers, and the use of radiation therapy to prevent lung cancer from spreading. They also report on effective new targeted therapies for cancers that have been historically difficult to treat, such as liver cancer and kidney cancer, among many others. A total of 24 advances are featured in this year's report. These advances and many more over the past several years show that the nation's long-term investment in cancer research is paying off. But there are disturbing signs that progress could slow. We are now in the midst of the longest sustained period of flat government funding for cancer research in history. The budgets for the National Institutes of Health and the National Cancer Institute (NCI) have been unchanged for four years. When adjusted for inflation, cancer research funding has actually declined 12% since 2004. These budget constraints limit the NCI's ability to fund promising cancer research. In the past several years the number of grants that the NCI has been able to fund has significantly decreased; this year, in response to just the

  12. Results of the 2005-2008 Association of Residents in Radiation Oncology Survey of Chief Residents in the United States: Clinical Training and Resident Working Conditions

    International Nuclear Information System (INIS)

    Purpose: To document clinical training and resident working conditions reported by chief residents during their residency. Methods and Materials: During the academic years 2005 to 2006, 2006 to 2007, and 2007 to 2008, the Association of Residents in Radiation Oncology conducted a nationwide survey of all radiation oncology chief residents in the United States. Chi-square statistics were used to assess changes in clinical training and resident working conditions over time. Results: Surveys were completed by representatives from 55 programs (response rate, 71.4%) in 2005 to 2006, 60 programs (75.9%) in 2006 to 2007, and 74 programs (93.7%) in 2007 to 2008. Nearly all chief residents reported receiving adequate clinical experience in commonly treated disease sites, such as breast and genitourinary malignancies; and commonly performed procedures, such as three-dimensional conformal radiotherapy and intensity-modulated radiotherapy. Clinical experience in extracranial stereotactic radiotherapy increased over time (p < 0.001), whereas clinical experience in endovascular brachytherapy (p <0.001) decreased over time. The distribution of gynecologic and prostate brachytherapy cases remained stable, while clinical case load in breast brachytherapy increased (p = 0.006). A small but significant percentage of residents reported receiving inadequate clinical experience in pediatrics, seeing 10 or fewer pediatric cases during the course of residency. Procedures involving higher capital costs, such as particle beam therapy and intraoperative radiotherapy, and infrequent clinical use, such as head and neck brachytherapy, were limited to a minority of institutions. Most residency programs associated with at least one satellite facility have incorporated resident rotations into their clinical training, and the majority of residents at these programs find them valuable experiences. The majority of residents reported working 60 or fewer hours per week on required clinical duties

    In this analysis, the authors examined the effects of different sets of process, structure, and environmental variables on the performance of the CCOP as a quasi-firm. Specifically, they distinguished between internal organizational processes, structural, and size characteristics of the CCOP and the organizational environment created by prior NCI program experience and the relationship within the quasi-firm. The analysis revealed that these sets of organizational and environmental characteristics have differential effects on treatment accrual. The strongest predictors are those associated with the quasi-firm relationship between the CCOP and its chosen research bases. Any definitive policy implications for the design of organizational network relationships--especially the CCOPs--will require further analysis. Particular attention needs to be given to the longitudinal nature of the relationships and the ability of these organizational and environmental factors to affect other aspects of performance. Several points have been made within this initial assessment. First, the structural character of the CCOP and its relationship to its organizational environment are important factors affecting accrual performance. The subtleties of this multivariate model are not as important as simply demonstrating that the various internal and external characteristics of these organizations as quasi-firms simultaneously affect their ability to accrue patients to clinical trials. Secondly, the importance of research base relations, and particularly the significant role of nurses, needs to be emphasized. While CCOPs were originally designed as a network of physicians and hospitals, it appears that an infrastructure of professionally active nurses working within a larger organizational environment is critical to success--at least as defined by accrual to treatment protocols. Finally, the failure of prior experience with other NCI community programs to affect CCOP accrual performance

    2006-01-01

    Full Text Available Abstract Background Escherichia coli is the model organism for which our knowledge of its regulatory network is the most extensive. Over the last few years, our project has been collecting and curating the literature concerning E. coli transcription initiation and operons, providing in both the RegulonDB and EcoCyc databases the largest electronically encoded network available. A paper published recently by Ma et al. (2004 showed several differences in the versions of the network present in these two databases. Discrepancies have been corrected, annotations from this and other groups (Shen-Orr et al., 2002 have been added, making the RegulonDB and EcoCyc databases the largest comprehensive and constantly curated regulatory network of E. coli K-12. Results Several groups have been using these curated data as part of their bioinformatics and systems biology projects, in combination with external data obtained from other sources, thus enlarging the dataset initially obtained from either RegulonDB or EcoCyc of the E. coli K12 regulatory network. We kindly obtained from the groups of Uri Alon and Hong-Wu Ma the interactions they have added to enrich their public versions of the E. coli regulatory network. These were used to search for original references and curate them with the same standards we use regularly, adding in several cases the original references (instead of reviews or missing references, as well as adding the corresponding experimental evidence codes. We also corrected all discrepancies in the two databases available as explained below. Conclusion One hundred and fifty new interactions have been added to our databases as a result of this specific curation effort, in addition to those added as a result of our continuous curation work. RegulonDB gene names are now based on those of EcoCyc to avoid confusion due to gene names and synonyms, and the public releases of RegulonDB and EcoCyc are henceforth synchronized to avoid confusion due to

    Introduction As part of the health care quality and safety policy in France, Professional Practice Assessment (P.P.A.) are mandatory in the health services 'certification' process. We present our study regarding the pertinence of Positron Emission Tomography (PET) indications in oncology. Materials and methods A multidisciplinary task group used the Quick Audit method with two rounds of 100 request forms each. The assessment list of criteria comprised four items of decreasing relevance grading the PET scans clinical indications, which were derived from the three French published guidelines (S.O.R. [F.N.C.L.C.C]., 'Guide du bon usage des examens d'imagerie medicale' [S.F.R.-S.F.M.N.], 'Guide pour la redaction de protocoles pour la TEP au F.D.G. en cancerologie' [S.F.M.N.]) and five additional items: clinical information, patient's body weight, previous treatments dates, diabetes, claustrophobia. Results The first round showed that 68% of the requested scans corresponded to the two most relevant groups of indications (S.O.R. Standards and Options). The request forms were correctly filled in regarding the clinical information, but this was not the case for the other items we tested. Several actions were conducted: dedicated PET request form, availability of the S.O.R. on the hospital intranet, boost of the referring physicians awareness during the multidisciplinary oncology meetings (Reunions de Concertation Pluridisciplinaires RCP). The second round showed a better pertinence of the PET scans indications (75% versus 68%); the patient's body weight was more frequently mentioned on the request form. Discussion This study is an example of P.P.A. in our discipline. It led to an improvement of the oncologic PET scans clinical indications in our hospital. This work is pursued in everyday discussion with the referring clinicians, especially during the RCP. (authors)

    Purpose To provide treatment recommendations for men with metastatic castration-resistant prostate cancer (CRPC). Methods The American Society of Clinical Oncology and Cancer Care Ontario convened an expert panel to develop evidence-based recommendations informed by a systematic review of the literature. Results When added to androgen deprivation, therapies demonstrating improved survival, improved quality of life (QOL), and favorable benefit-harm balance include abiraterone acetate/prednisone, enzalutamide, and radium-223 (223Ra; for men with predominantly bone metastases). Improved survival and QOL with moderate toxicity risk are associated with docetaxel/prednisone. For asymptomatic/minimally symptomatic men, improved survival with unclear QOL impact and low toxicity are associated with sipuleucel-T. For men who previously received docetaxel, improved survival, unclear QOL impact, and moderate to high toxicity risk are associated with cabazitaxel/prednisone. Modest QOL benefit (without survival benefit) and high toxicity risk are associated with mitoxantrone/prednisone after docetaxel. No benefit and excess toxicity are observed with bevacizumab, estramustine, and sunitinib. Recommendations Continue androgen deprivation (pharmaceutical or surgical) indefinitely. Abiraterone acetate/prednisone, enzalutamide, or 223Ra should be offered; docetaxel/prednisone should also be offered, accompanied by discussion of toxicity risk. Sipuleucel-T may be offered to asymptomatic/minimally symptomatic men. For men who have experienced progression with docetaxel, cabazitaxel may be offered, accompanied by discussion of toxicity risk. Mitoxantrone may be offered, accompanied by discussion of limited clinical benefit and toxicity risk. Ketoconazole or antiandrogens (eg, bicalutamide, flutamide, nilutamide) may be offered, accompanied by discussion of limited known clinical benefit. Bevacizumab, estramustine, and sunitinib should not be offered. There is insufficient evidence to

    This guideline provides recommendations for the use of PET imaging in gliomas. The review examines established clinical benefit in glioma patients of PET using glucose ((18)F-FDG) and amino acid tracers ((11)C-MET, (18)F-FET, and (18)F-FDOPA). An increasing number of studies have been published on PET imaging in the setting of diagnosis, biopsy, and resection as well radiotherapy planning, treatment monitoring, and response assessment. Recommendations are based on evidence generated from studies which validated PET findings by histology or clinical course. This guideline emphasizes the clinical value of PET imaging with superiority of amino acid PET over glucose PET and provides a framework for the use of PET to assist in the management of patients with gliomas.

  18. Imaging Opportunities in Radiation Oncology

    International Nuclear Information System (INIS)

    Interdisciplinary efforts may significantly affect the way that clinical knowledge and scientific research related to imaging impact the field of Radiation Oncology. This report summarizes the findings of an intersociety workshop held in October 2008, with the express purpose of exploring 'Imaging Opportunities in Radiation Oncology.' Participants from the American Society for Radiation Oncology (ASTRO), National Institutes of Health (NIH), Radiological Society of North America (RSNA), American Association of physicists in Medicine (AAPM), American Board of Radiology (ABR), Radiation Therapy Oncology Group (RTOG), European Society for Therapeutic Radiology and Oncology (ESTRO), and Society of Nuclear Medicine (SNM) discussed areas of education, clinical practice, and research that bridge disciplines and potentially would lead to improved clinical practice. Findings from this workshop include recommendations for cross-training opportunities within the allowed structured of Radiology and Radiation Oncology residency programs, expanded representation of ASTRO in imaging related multidisciplinary groups (and reciprocal representation within ASTRO committees), increased attention to imaging validation and credentialing for clinical trials (e.g., through the American College of Radiology Imaging Network (ACRIN)), and building ties through collaborative research as well as smaller joint workshops and symposia.

    Full Text Available Purpose/Objective: While our department is heavily invested in computer-based treatment planning, we historically relied on paper-based charts for management of Radiation Oncology patients. In early 2009, we initiated the process of conversion to an electronic medical record (EMR eliminating the need for paper charts. Key goals included the ability to readily access information wherever and whenever needed, without compromising safety, treatment quality, confidentiality or productivity.Methodology: In February, 2009, we formed a multi-disciplinary team of Radiation Oncology physicians, nurses, therapists, administrators, physicists/dosimetrists, and information technology (IT specialists, along with staff from the Duke Health System IT department. The team identified all existing processes and associated information/reports, established the framework for the EMR system and generated, tested and implemented specific EMR processes.Results: Two broad classes of information were identified: information which must be readily accessed by anyone in the health system versus that used solely within the Radiation Oncology department. Examples of the former are consultation reports, weekly treatment check notes and treatment summaries; the latter includes treatment plans, daily therapy records and quality assurance reports. To manage the former, we utilized the enterprise-wide system , which required an intensive effort to design and implement procedures to export information from Radiation Oncology into that system. To manage "Radiation Oncology" data, we used our existing system (ARIA, Varian Medical Systems. The ability to access both systems simultaneously from a single workstation (WS was essential, requiring new WS and modified software. As of January, 2010, all new treatments were managed solely with an EMR. We find that an EMR makes information more widely accessible and does not compromise patient safety, treatment quality or confidentiality

  20. American Society of Clinical Oncology policy statement update: tobacco control--reducing cancer incidence and saving lives. 2003.

    Science.gov (United States)

    2003-07-15

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

    In oncology, PET and PET/CT with tracers beyond FDG target more specific biological processes, such as proliferation ({sup 18}F-3'-fluoro-3'-deoxy-L-thymidine; {sup 18}F-FLT), tumour hypoxia ({sup 18}F-fluoromisonidazol; {sup 18}F-FMISO) and phospholipid metabolism (radioactively labelled choline derivates). FLT is a thymidine analogue which can be labelled with {sup 18}F. PET with {sup 18}F-FLT enables to non-invasively image and to quantify the proliferation fraction of tumours. Proliferation dependent accumulation of FLT has been demonstrated for a variety of solid and haematologic neoplasms including lung cancer, breast cancer, gastric cancer, colorectal cancer and malignant lymphoma. Furthermore, FLT has been suggested as surrogate marker for the assessment of response to treatment, especially when targeted drugs are utilized. PET imaging in particular has emerged as a promising non-invasive tool to accurately characterize tumour oxygenation. The great promise of PET/CT is its potential as a single imaging modality for whole body staging that provides anatomical and biological information on the disease as a whole. It allows a more precise estimation of the hypoxic tumour volume as well as comparisons on a voxel-by-voxel basis (parametric mapping). PET and PET/CT with hypoxia tracers thus offer the potential to optimize and individualize therapy for patients suffering from cancer. PET- and PET/CT-studies using {sup 11}C- or {sup 18}F-labeled choline derivates recently have shown promising results for re-staging prostate cancer in patients with biochemical recurrence and advanced prostate cancer. In patients with biochemical recurrence of prostate cancer after primary therapy the detection rate of {sup 11}C-choline- PET/CT shows a positive relationship with serum PSA-levels. In these patients {sup 11}C-choline PET/CT allows not only to diagnose but also to localize recurrent disease with implications on disease management (localised vs. systemic

    Full Text Available Patients with malignancies are subject to develop a unique set of urgent and life-threatening complications. These emergency problems can be the result of the disease itself, the result from the therapy directed against the cancer or the result of previously existing pathological conditions not related to cancer. In some cases, these problems are the first symptom of the tumor. Aim: The aim of this study was to review the literature regarding the oncologic emergencies. Method: The method of this study included bibliography research from both the review and the research literature, mainly in the on-line data base 'Pubmed'. Results: Tumor lysis syndrome, malignant spinal cord compression, superior vena cava syndrome, cardiovascular emergencies, acute renal failure, venous thrombosis and pulmonary embolism, metabolic emergencies, neutropenic infection, acute pulmonary problems, acute hemorrhage and hematuria are the most important oncologic emergencies. Conclusions: Early diagnosis of the oncologic emergencies and prompt interventions can be lifesaving. However, staging of the tumor, response to current treatment, overall prognosis and patient and family wishes should be assessed in order to establish an appropriate treatment plan.

    The Istituto di Ricovero e Cura a Carattere Scientifico (IRCCS) Istituto Nazionale Tumori "Fondazione G. Pascale" (INT-Pascale) is the largest Clinical Care and Research Cancer Center in Southern Italy. The mission is prevention, diagnosis, and care of cancer and innovative research in oncology. In 2013, INT-Pascale joined the Organisation of European Cancer Institutes (OECI) accreditation and classification project along with other Italian IRCCS cancer centers. One of the major OECI requirements that a cancer center must fulfill in order to achieve and maintain OECI certification is a strong emphasis in translational and clinical research: increasing the number of patients enrolled in clinical trials, establishing easily accessible databases for operators, and informing all possible stakeholders, including patients. A characterizing theme of INT-Pascale is a strong commitment to clinical experimental studies. In the 2007-2014 period, 440 clinical trials were activated at INT-Pascale; in this period, the number of clinical trials and observational studies has had an increment achieving in 2014, respectively, the share of 60 clinical trials and 35 observational studies activated. Optimization of clinical trials management and dissemination of the clinical research culture at INT-Pascale are main objectives to be achieved through several actions and procedures being implemented as a component of the OECI improvement plan. Participation in the OECI program has represented an important challenge to improve quality and processes related to promoting, prioritizing, and monitoring clinical trials at INT-Pascale.

    2012-12-01

    As part of the Long Term Ecological Research (LTER) program, the Harvard Forest in Petersham, Massachusetts seeks to train the next generation of researchers, by involving K-12 grade students and their teachers in hands-on, field-based, ecological research in their own schoolyard and community. Students learn to collect data on important long-term ecological issues and processes. Student data are then shared on the Harvard Forest website. To prepare teachers for project protocols, teachers are given direct access to Harvard ecologists with professional development workshops and on-line resources. With the Harvard Forest Schoolyard LTER program, students can participate in three different research projects focusing on phenology, invasive insects, and vernal pools. Teachers attend the Summer Institute for Teachers to learn project content and methods. They return in fall to participate in one of three levels of data workshops to learn how to input, manage, and analyze project data. In the spring, teachers again meet with the Harvard ecologists about project protocols, and to share, through a series of teacher presentations, the ways these project themes are being integrated into class curricula. These professional development opportunities result in long term collaborative partnerships with local schools and the Harvard Forest LTER. In addition to the LTER Schoolyard Ecology Program, the Harvard Forest has supported a successful Research Experience for Teachers (RET) program for the last six years. Throughout the summer, teachers work on research projects alongside Harvard Forest and affiliated scientists, post-docs, graduate students, and REU's (Research Experience for Undergraduates). The RET program provides teachers with the opportunity to build scientific knowledge, develop an understanding of research methods, and translate their new knowledge and experiences into cutting edge classroom lessons. The past two summers I have worked with Dr. Andrew Richardson

  6. "Flipping" educational technology professional development for K-12 educators

    Science.gov (United States)

    Spencer, Daniel

    As the demand for more effective professional development increases in K-12 schools, trainers must adjust their training methods to meet the needs of their teacher learners. Just as lecture-heavy, teacher-centered instruction only meet the learning needs of a small minority of students, "sit and get" professional development rarely results in the teachers gaining the skills and confidence necessary to use technology effectively in their instruction. To resolve the frustrations of teachers related to ineffective professional development, a "Flipped PD" training model was developed based on the learning needs of adult learners, the integration of technological, pedagogical, and content knowledge (TPACK), learning activities, and the Flipped Classroom concept. Under this model, training shifts from a passive, trainer-centered format, to an active, learner-centered format where teachers learn to use technology in their classrooms by first focusing on pedagogical issues, then choosing the options that work best for addressing those issues in their unique situation, and completing "learn-by-doing" projects. Those who participate in "Flipped PD" style trainings tend to have more confidence upon completion that they can use the tools they were trained on in their teaching, as well as believe that the PD was engaging and a good use of their time.

We found that the presence of transfer constitutive IncF plasmids induced biofilm development forming structures resembling those reported for Pseudomonas aeruginosa . The development occurred in a step....... We further provide evidence that flagella, type 1 fimbriae, curli and Ag43 are all dispensable for the observed biofilm maturation. In addition, our results indicate that cell-to-cell signalling mediated by autoinducer 2 (AI-2) is not required for differentiation of E. coli within a biofilm community....... We suggest on the basis of these results that E. coli K-12 biofilm development and maturation is dependent on cell-cell adhesion factors, which may act as inducers of self-assembly processes that result in differently structured biofilms depending on the adhesive properties on the cell surface....

  11. External audit of clinical practice and medical decision making in a new Asian oncology center: Results and implications for both developing and developed nations

    International Nuclear Information System (INIS)

    Purpose: The external audit of oncologist clinical practice is increasingly important because of the incorporation of audits into national maintenance of certification (MOC) programs. However, there are few reports of external audits of oncology practice or decision making. Our institution (The Cancer Institute, Singapore) was asked to externally audit an oncology department in a developing Asian nation, providing a unique opportunity to explore the feasibility of such a process. Methods and Materials: We audited 100 randomly selected patients simulated for radiotherapy in 2003, using a previously reported audit instrument assessing clinical documentation/quality assurance and medical decision making. Results: Clinical documentation/quality assurance, decision making, and overall performance criteria were adequate 74.4%, 88.3%, and 80.2% of the time, respectively. Overall 52.0% of cases received suboptimal management. Multivariate analysis revealed palliative intent was associated with improved documentation/clinical quality assurance (p = 0.07), decision making (p 0.007), overall performance (p = 0.003), and optimal treatment rates (p 0.07); non-small-cell lung cancer or central nervous system primary sites were associated with better decision making (p = 0.001), overall performance (p = 0.03), and optimal treatment rates (p = 0.002). Conclusions: Despite the poor results, the external audit had several benefits. It identified learning needs for future targeting, and the auditor provided facilitating feedback to address systematic errors identified. Our experience was also helpful in refining our national revalidation audit instrument. The feasibility of the external audit supports the consideration of including audit in national MOC programs

  12. Ethical issues at the interface of clinical care and research practice in pediatric oncology: a narrative review of parents' and physicians' experiences

    2011-09-01

    Full Text Available Abstract Background Pediatric oncology has a strong research culture. Most pediatric oncologists are investigators, involved in clinical care as well as research. As a result, a remarkable proportion of children with cancer enrolls in a trial during treatment. This paper discusses the ethical consequences of the unprecedented integration of research and care in pediatric oncology from the perspective of parents and physicians. Methodology An empirical ethical approach, combining (1 a narrative review of (primarily qualitative studies on parents' and physicians' experiences of the pediatric oncology research practice, and (2 comparison of these experiences with existing theoretical ethical concepts about (pediatric research. The use of empirical evidence enriches these concepts by taking into account the peculiarities that ethical challenges pose in practice. Results Analysis of the 22 studies reviewed revealed that the integration of research and care has consequences for the informed consent process, the promotion of the child's best interests, and the role of the physician (doctor vs. scientist. True consent to research is difficult to achieve due to the complexity of research protocols, emotional stress and parents' dependency on their child's physician. Parents' role is to promote their child's best interests, also when they are asked to consider enrolling their child in a trial. Parents are almost never in equipoise on trial participation, which leaves them with the agonizing situation of wanting to do what is best for their child, while being fearful of making the wrong decision. Furthermore, a therapeutic misconception endangers correct assessment of participation, making parents inaccurately attribute therapeutic intent to research procedures. Physicians prefer the perspective of a therapist over a researcher. Consequently they may truly believe that in the research setting they promote the child's best interests, which maintains the

  13. Cool Science: K-12 Climate Change Art Displayed on Buses

    Chen, R. F.; Lustick, D. S.; Lohmeier, J.; Thompson, S. R.

    2015-12-01

    Cool science is an art contest where K12 students create placards (7" x 22") to educate the public about climate change. Students are prompted to create their artwork in response to questions such as: What is the evidence for climate change? How does climate change impact your local community? What can you do to reduce the impacts of climate change? In each of three years, 500-600 student entrees have been submitted from more than 12 school districts across Massachusetts. A panel of judges including scientists, artists, rapid transit representatives, and educators chooses elementary, middle, and high school winners. Winners (6), runners-up (6), and honorable mentions (12) and their families and teachers are invited to an annual Cool Science Award Ceremony to be recognized and view winning artwork. All winning artwork is posted on the Cool Science website. The winning artwork (2 per grade band) is converted into placards (11" x 28") and posters (2.5' x 12') that are placed on the inside (placards) and outside (posters) of buses. Posters are displayed for one month. So far, Cool Science was implemented in Lowell, MA where over 5000 public viewers see the posters daily on the sides of Lowell Rapid Transit Authority (LRTA) buses, making approximately 1,000,000 impressions per year. Cool Science acts to increase climate literacy in children as well as the public, and as such promotes intergenerational learning. Using art in conjunction with science learning about climate change appears to be effective at engaging not just traditionally high achieving science students, but also those interested in the creative arts. Hearing winners' stories about how they created their artwork and what this contest meant to them supports the idea that Cool Science attracts a wide diversity of students. Parents discuss climate change with their children. Multiple press releases announcing the winners further promotes the awareness of climate change throughout school districts and their

    This paper reports on the delivery of radiotherapy to the primary site and lymphatic pathways in the management of early stage breast cancer. Radiotherapists were clear that their aim of locoregional radiotherapy was to reduce local recurrence. However, variation in policies for delivery were seen: 80% of radiotherapists did not always give radiotherapy routinely following wide local excision as part of breast conserving management; instead they withheld it selectively for a number of reasons. Only 66% routinely used breast boosts. There was a range of indications for giving radiotherapy to the lymphatic pathways; there was also variation in the management of incompletely or marginally excised primary tumours. Most sources of variation in the practice of radiotherapy in the management of women with early stage breast cancer appeared to arise from scientific uncertainty. However, organizational issues influenced many decisions. These scientific uncertainties and organizational issues are best addressed in the context of multidisciplinary breast clinics. PMID:8845315

    The Teachers on the Leading Edge (TOTLE) program has designed an innovative model for middle school teacher professional development related to Pacific NW plate margin hazards and EarthScope science. The program has been effective at improving teacher knowledge and confidence and has led to high rates of curricular implementation. The elements particularly key to success are: a) facilitation team with broad expertise in both geoscience and education; b) regional team format that encouraged learning community development; c) teachers' desire to focus on regional geologic hazards; d) significant use of animations and field trips to aid in "visualization" of processes; and e) extensive "kit" of teaching materials for easy classroom transfer. The 1-week workshops were held in summer 2008-2010 and 35 Pacific NW middle school teachers attended each year. Geoscientists from universities and research institutions conducted the field trips and content sessions. Master K-12 Earth science teachers designed or modified curricular materials and led the teaching implementation sessions. Each year, the teachers were divided into 5 regional teams led by geoscience educator team leaders (community college instructors or similar). Teachers were surveyed on teaching confidence and content knowledge before and after the workshops. Follow-up surveys addressed teaching confidence and curricular implementation and were conducted 0.7 years after (all cohorts), 1.7 years after (2009 cohort), and 2.7 years after (2008 cohort). Teacher confidence (4-point scale: 1="not at all confident"; 4="very confident") on workshop content topics continued to rise in each subsequent survey from 2.7 (pre) to 3.3 (post) to 3.5 (0.7 yr follow up) to 3.7 (2-3 yr follow up) suggesting the program impact is long-lived. In the post-workshop surveys, 100% of participants agreed or strongly agreed that the program would positively impact their teaching. Average teacher performance on content questions improved

    Respiratory motion may cause significant image artefacts in positron emission tomography/computed tomography (PET/CT) imaging. This study introduces a new bioimpedance-based gating method for minimizing respiratory artefacts. The method was studied in 12 oncologic patients by evaluating the following three parameters: maximum metabolic activity of radiopharmaceutical accumulations, the size of these targets as well as their target-to-background ratio. The bioimpedance-gated images were compared with non-gated images and images that were gated with a reference method, chest wall motion monitoring by infrared camera. The bioimpedance method showed clear improvement as increased metabolic activity and decreased target volume compared to non-gated images and produced consistent results with the reference method. Thus, the method may have great potential in the future of respiratory gating in nuclear medicine imaging.

    Previous studies of the bacteriocin-producing Streptococcus salivarius K12 monitored a variety of intrinsic strain characteristics of potential relevance to its application as an oral probiotic in humans. These included the content of antibiotic resistance and virulence determinants, the production of deleterious metabolic by-products and its genetic stability. In the present study, we examined additional safety factors including the responses of rats to either short- or long-term oral dosing with strain K12 preparations. In addition, the potential genotoxicity of strain K12 was tested using a bacterial reverse mutation assay. To determine the occurrence and concentrations in human saliva of S. salivarius having the same bacteriocin phenotype as strain K12, saliva samples from 780 children were evaluated. The level of dosing with strain K12 required to achieve oral cavity colonization levels similar to those occurring naturally for this type of bacteriocin-producing S. salivarius was established using 100 human subjects. Following the oral instillation of lyophilized S. salivarius K12 cells in these subjects, its persistence was not at levels higher than those found naturally for this type of bacterium. The various sets of data obtained in this study showed no evidence of genotoxicity and no acute or subacute toxicity effects associated with strain K12. Based on the previously published data, the long history of use by humans and the information presented here, it is concluded that S. salivarius K12 is safe for human consumption. PMID:26781236

    Background. The aim of this study was to monitor oropharyngeal bacterial colonization in patients indicated for percutaneous endoscopic gastronomy (PEG). Methods. Oropharyngeal swabs were obtained from patients prior to PEG placement. A development of peristomal infection was evaluated. The analysis of oropharyngeal and peristomal site pathogens was done. Results. Consecutive 274 patients referred for PEG due to neurological disorder or cancer completed the study. Oropharyngeal colonization with pathogens was observed in 69% (190/274), dominantly in the neurologic subgroup of patients (P < 0.001). Peristomal infection occurred in 30 (10.9%) of patients and in 57% of them the correlation between oropharyngeal and peristomal agents was present. The presence of oropharyngeal pathogens was assessed as an important risk factor for the development of peristomal infection only in oncological patients (OR = 8.33, 95% CI: 1.66–41.76). Despite a high prevalence of pathogens in neurological patients, it did not influence the risk of peristomal infection with the exception for methicillin resistant Staphylococcus aureus (MRSA) carriers (OR 4.5, 95% CI: 1.08–18.76). Conclusion. During oropharyngeal microbial screening prior to the PEG insertion, the detection of pathogens may be a marker of the increased risk of peristomal infection in cancer patients only. In neurological patients the benefit of the screening is limited to the detection of MRSA carriers. PMID:25243153

Although its cause is not yet perfectly established, the pathology, often a sequel of acute otitis media (AOM, is mainly characterized by persistent fluid in the middle ear cavity. Twenty-two children with a diagnosis of SOM were treated daily for 90 days with an oral formulation containing the oral probiotic Streptococcus salivarius K12 (Bactoblis®. After treatment, the children were evaluated for AOM episodes and subjected to tone audiometry, tympanometry, endonasal endoscopy, otoscopy, and tonsillar examination. Subject compliance and probiotic tolerability and side effects have also been evaluated. Our results indicate a good safety profile, a substantial reduction of AOM episodes, and a positive outcome from the treatment for all of the clinical outcomes tested. We conclude that strain K12 may have a role in reducing the occurrence and/or severity of SOM in children. From our perspective, this study constitutes a starting point toward the organization of a more extensive placebo-controlled study aimed at critically appraising our preliminary observations.

    In 1949, the department of gynaecology was set up. After a brief historical draft describing the development of the oncological center, we draw attention to the advantages of its multidisciplinary structure demonstrated in our cooperation with that of radiotherapy. The kinds of treatment and their results are reported with regard to the carcinomas of the cervix, corpus and vulva. Radiotherapy of the carcinoma of the cervix using a modified Stockholm method covers two sessions, with an interval of two to three weeks during which 60 mg radium (= 1600 mgh) intrauterine and twice 30 mg radium (= 1600 mgh) intravaginal are applied for 26.5 hours combined with a percutaneous irradiation of the parametries with 3500 to 4000 rad (gammatron, /sup 60/Co; betatron, 42 MeV). We prefer surgical therapy for the carcinoma of the cervix in the Ia, Ib and IIa stages up to the age of 65. We operated on 604 patients between 1957 and 1978, all of them receiving additional radiotherapy, a third preoperative irradiation. Carcinoma of the corpus has rarely been treated surgically in account of the negative selection of our patients. The radiotherapeutic procedure mostly applied is the tamponade of the uterine cavum whereby twelfe 10-mg radium tubes are applied in two sessions for 25 hours, 6000 mgh in all, plus a vaginal implant of 1500 mgh in stage-I cases, and in stage-II cases 3000 mgh intravaginally and a percutaneous telecobalt-dose of 3000 to 4000 rad. Carcinoma of the vulva is, if possible, primarily to be treated surgically by radical vulvectomy and lymphadenectomy of the inguinal and subinguinal lymphodes. Postoperative radiotherapy is carried out, when the lymphodes are positive.

  19. Introduction of online adaptive radiotherapy for bladder cancer through a multicentre clinical trial (Trans-Tasman Radiation Oncology Group 10.01): lessons learned

    International Nuclear Information System (INIS)

    Online adaptive radiotherapy for bladder cancer is a novel radiotherapy technique that was found feasible in a pilot study at a single academic institution. In September 2010 this technique was opened as a multicenter study through the Trans-Tasman Radiation Oncology Group (TROG 10.01 bladder online adaptive radiotherapy treatment). Twelve centers across Australia and New-Zealand registered interest into the trial. A multidisciplinary team of radiation oncologists, radiation therapists and medical physicists represented the trial credentialing and technical support team. To provide timely activation and proper implementation of the adaptive technique the following key areas were addressed at each site: Staff education/training; Practical image guided radiotherapy assessment; provision of help desk and feedback. The trial credentialing process involved face-to-face training and technical problem solving via full day site visits. A dedicated 'help-desk' team was developed to provide support for the clinical trial. 26% of the workload occurred at the credentialing period while the remaining 74% came post-center activation. The workload was made up of the following key areas; protocol clarification (36%), technical problems (46%) while staff training was less than 10%. Clinical trial credentialing is important to minimizing trial deviations. It should not only focus on site activation quality assurance but also provide ongoing education and technical support.

    The history of oncology in Slovakia is closely linked to the history of St. Elizabeth Hospital, which was set up in the mid-18th century by nuns of the St. Elizabeth Order in Bratislava. In the first half of the 20th century, a unit was set up in the hospital dedicated to diagnosis and treatment of cancer. Shortly after World War II, the unit was turned into the Institute for Cancer Research and Treatment. In 1950, St. Elizabeth Hospital was nationalized, and the Cancer Research Institute of the Slovak Academy of Science and the Institute of Clinical Oncology were located there as centers for oncological diagnosis and treatment. After the restitution of church property in the early 1990s, the hospital was returned to the Order of St. Elizabeth, which set up the St. Elisabeth Cancer Institute in the hospital premises in January of 1996. This year marks the 20th anniversary of this institute in its new premises and the 85th anniversary of the Institute of Radiumtherapy founded in Bratislava, and thus the establishment of institutional healthcare for cancer patients in Slovakia is the reason for balancing. We present a view of the consecutive changes in the organization, space and staff of the Institute and evaluate the impact of celebrities on medicine who developed oncology as a clinical, scientific and educational discipline in Bratislava and in other cities and regions of Slovakia.

  3. Palliative medicine and medical oncology.

    Traditionally, medical oncology and palliative care have been considered two distinct and separate disciplines, both as regards treatment objectives and delivery times. Palliative care in terminal stages, aimed exclusively at evaluating and improving quality of life, followed antitumor therapies, which concentrated solely on quantitative results (cure, prolongation of life, tumoral mass shrinkage). Over the years, more modern concepts have developed on the subject. Medical oncology, dealing with the skills and strategic co-ordination of oncologic interventions from primary prevention to terminal phases, should also include assessment and treatment of patients' subjective needs. Anticancer therapies should be evaluated in terms of both the quantitative and qualititative impact on patients' lives. Hence, the traditional view of palliative care has to be modified: it constitutes a philosophical and methodological approach to be adopted from the early phases of illness. It is not the evident cultural necessity of integrating medical oncology with palliative medicine that may be a matter of argument, but rather the organizational models needed to put this combined care into practice: should continuous care be guaranteed by a single figure, the medical oncologist, or rather by an interdisciplinary providers' team, including full-time doctors well-equipped for palliative care? In this paper the needs of cancer patients and the part that a complete oncologist should play to deal with such difficult and far-reaching problems are firstly described. Then, as mild provocation, data and critical considerations on the ever increasing needs of palliative care, the present shortcomings in quality of life and pain assessment and management by medical oncologists, and the uncertain efficacy of interventional programmes to change clinical practice are described. Finally, a model of therapeutic continuity is presented. which in our view is realistic and feasible: an Oncologic

  7. Radiation Therapy Oncology Group Consensus Panel Guidelines for the Delineation of the Clinical Target Volume in the Postoperative Treatment of Pancreatic Head Cancer

    International Nuclear Information System (INIS)

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

    2014-06-01

    Full Text Available Kaposi's sarcoma is a multifocal vascular lesion of low-grade potential that is most often present in mucocutaneous sites and usually also affects lymph nodes and visceral organs. The condition may manifest through purplish lesions, flat or raised with an irregular shape, gastrointestinal bleeding due to lesions located in the digestive system, and dyspnea and hemoptysis associated with pulmonary lesions. In the early 1980s, the appearance of several cases of Kaposi's sarcoma in homosexual men was the first alarm about a newly identified epidemic, acquired immunodeficiency syndrome. In 1994, it was finally demonstrated that the presence of a herpes virus associated with Kaposi's sarcoma called HHV-8 or Kaposi's sarcoma herpes virus and its genetic sequence was rapidly deciphered. The prevalence of this virus is very high (about 50% in some African populations, but stands between 2% and 8% for the entire world population. Kaposi's sarcoma only develops when the immune system is depressed, as in acquired immunodeficiency syndrome, which appears to be associated with a specific variant of the Kaposi's sarcoma herpes virus. There are no treatment guidelines for Kaposi's sarcoma established in Brazil, and thus the Brazilian Society of Clinical Oncology and the Brazilian Society of Infectious Diseases developed the treatment consensus presented here.

    Objective A Question Prompt List (QPL) is a proven, simple intervention to aid patients to be active participants in consultations with their physicians by asking questions. We aimed to further develop and test the efficacy of a targeted QPL for clinical trials (QPL-CT). Methods Breast, Lung and Genitourinary cancer patients who were facing a discussion about a therapeutic clinical trial completed short pre- and post-consultation questionnaires and used the QPL-CT in their discussions with their oncologists. Results: 30 participants were recruited from 6 oncologists All QPL-CT questions were selected by at least one-third of participants. Participants mostly wanted and asked questions about personal trial benefit. Oncologists provided information about personal benefit to varying degrees, thus patients did not ask some questions. Patients were still left with some unasked and unanswered questions. Conclusion The QPL-CT has potential as a simple, inexpensive intervention to aid such communication. Further investigation is needed to demonstrate the efficacy of the QPL-CT in improving cancer patient outcomes. Practice Implications These preliminary finding suggest that important areas of clinical trials are overlooked in clinical consultations. The QPL-CT may be an effective method to encourage oncologists to endorse patient question asking about clinical trials and prompt patient questions. PMID:22390854

  11. Development of an Attitude Scale to Assess K-12 Teachers' Attitudes toward Nanotechnology

    To maximize the contributions of nanotechnology to this society, at least 60 countries have put efforts into this field. In Taiwan, a government-funded K-12 Nanotechnology Programme was established to train K-12 teachers with adequate nanotechnology literacy to foster the next generation of Taiwanese people with sufficient knowledge in nanotechnology. In the present study, the Nanotechnology Attitude Scale for K-12 teachers (NAS-T) was developed to assess K-12 teachers' attitudes toward nanotechnology. The NAS-T included 23 Likert-scale items that can be grouped into three components: importance of nanotechnology, affective tendencies in science teaching, and behavioural tendencies to teach nanotechnology. A sample of 233 K-12 teachers who have participated in the K-12 Nanotechnology Programme was included in the present study to investigate the psychometric properties of the NAS-T. The exploratory factor analysis of this teacher sample suggested that the NAS-T was a three-factor model that explained 64.11% of the total variances. This model was also confirmed by the confirmatory factor analysis to validate the factor structure of the NAS-T. The Cronbach's alpha values of three NAS-T subscales ranged from 0.89 to 0.95. Moderate to strong correlations among teachers' NAS-T domain scores, self-perception of own nanoscience knowledge, and their science-teaching efficacy demonstrated good convergent validity of the NAS-T. As a whole, psychometric properties of the NAS-T indicated that this instrument is an effective instrument for assessing K-12 teachers' attitudes toward nanotechnology. The NAS-T will serve as a valuable tool to evaluate teachers' attitude changes after participating in the K-12 Nanotechnology Programme.

    The use of somatostatin (SS) analogues in humans takes advantage by the availability of many related chemical forms that can be used for receptor therapy and, after radiolabelling, for diagnostic imaging and radionuclide therapy. The first proposed radiocompound, yet clinically widely diffuse, has been (111)In-octreotide (OCT), followed by positron emission tomography (PET) and beta emitter tracers. The main field of clinical applications is in neuroendocrine tumours (NET), starting by the demonstration of SS receptors (SSR) on the majority of NET, particularly on gastroenteropancreatic (GEP) tumours. Uptake of SS analogues can also be due to a SSR expression on non malignant cells when activated, as lymphocytes, macrophages, fibroblasts , vascular cells. Because of this uptake clinical indications can be found also in active benign diseases, as Grave's ophthalmopathy, rheumatoid arthritis, histiocitosis, sarcoidosis, idiopatic pulmonary fibrosis. Moreover, these cells can also determine the OCT in vivo uptake in tumours non expressing in vitro SSR, as non-snall cell lung cancer (NSCLC). Because of a different kinetic respect to SCLC a differential histotype diagnosis could be obtained. Starting from this premise OCT can also allows radioguided surgery in tumours non expressing SSR. Finally a relevant clinical role can be defined in the a priori recruitment and as marker of therapeutic efficacy in all the therapeutic strategies utilizing SSR, both in malignant and benign diseases.

  15. Radiotherapy quality assurance review in a multi-center randomized trial of limited-disease small cell lung cancer: the Japan Clinical Oncology Group (JCOG) trial 0202

    International Nuclear Information System (INIS)

    The purpose of this study was to analyze the radiotherapy (RT) quality assurance (QA) assessment in Japan Clinical Oncology Group (JCOG) 0202, which was the first trial that required on-going RT QA review in the JCOG. JCOG 0202 was a multi-center phase III trial comparing two types of consolidation chemotherapy after concurrent chemoradiotherapy for limited-disease small cell lung cancer. RT requirements included a total dose of 45 Gy/30 fx (bis in die, BID/twice a day) without heterogeneity correction; elective nodal irradiation (ENI) of 30 Gy; at least 1 cm margin around the clinical target volume (CTV); and interfraction interval of 6 hours or longer. Dose constraints were defined in regards to the spinal cord and the lung. The QA assessment was classed as per protocol (PP), deviation acceptable (DA), violation unacceptable (VU), and incomplete/not evaluable (I/NE). A total of 283 cases were accrued, of which 204 were fully evaluable, excluding 79 I/NE cases. There were 18 VU in gross tumor volume (GTV) coverage (8% of 238 evaluated); 4 VU and 23 DA in elective nodal irradiation (ENI) (2% and 9% of 243 evaluated, respectively). Some VU were observed in organs at risk (1 VU in the lung and 5 VU in the spinal cord). Overall RT compliance (PP + DA) was 92% (187 of 204 fully evaluable). Comparison between the former and latter halves of the accrued cases revealed that the number of VU and DA had decreased. The results of the RT QA assessment in JCOG 0202 seemed to be acceptable, providing reliable results

  16. Significance of chronic marked hyperglycemia on FDG-PET. Is it really problematic for clinical oncologic imaging?

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate the adverse effects of chronic marked hyperglycemia on clinical diagnostic performance of positron emission tomography (PET) using 18F-fluorodeoxyglucose (FDG). Fifty-seven scans of 54 patients, who received FDG-PET for the diagnosis of various cancer(s), and who showed high plasma glucose level of more than 200 mg/dl at the time of administration of FDG in spite of at least 4-h fasting, were retrospectively analyzed. In the clinical follow-up, this high plasma glucose was confirmed as chronic hyperglycemia derived from uncontrolled diabetes (n=32) and untreated diabetes (n=25). Based on the final diagnosis of malignancy obtained by histopathology or clinical follow-up for at least 6 months, the diagnostic performance of visual PET analysis was evaluated. Excluding nine scans of nine patients without sufficient follow-up, final diagnosis was obtained in 48 scans of 45 patients. In 36 scans of 36 patients, at least one malignant lesion was finally confirmed, and true-positive and false-negative results were obtained in 30 and six cases, respectively. Six cases showed false-negative results due to low FDG-avid pathological characteristics (hepatocellular carcinoma, etc.), chemotherapeutic effect or small tumor size. Overall, the patient-based sensitivity, specificity, positive predictive value, negative predictive value and diagnostic accuracy were 83, 83, 94, 63 and 83%, respectively. In lesion-based diagnosis, 56 of 75 lesions (74%) were depicted by PET, while 19 lesions were negative on PET, also due to low FDG-avid characteristics or small size (less than 15 mm). At the time of chronic hyperglycemia (not acute hyperglycemia), the adverse effect caused by high plasma glucose level was minimum. The FDG uptake of the tumor maintained a sufficiently high level for visual clinical diagnosis in most cases, except in the cases of low FDG-avid tumors or small lesions (15 mm in size). (author)

    Full Text Available Abstract Background Cancer diseases and their therapies have negative effects on the quality of life. The aim of this study is to assess the effectiveness of case management in a sample of oncological outpatients with the intent of rehabilitation after cancer treatment. Case management wants to support the complex information needs of the patients in addition to the segmented structure of the health care system. Emphasis is put on support for self-management in order to enhance health - conscious behaviour, learning to deal with the burden of the illness and providing the opportunity for regular contacts with care providers. We present a study protocol to investigate the efficacy of a case management in patients following oncology rehabilitation after cancer treatment. Methods The trial is a multicentre, two-arm randomised controlled study. Patients are randomised parallel in either 'usual care' plus case management or 'usual care' alone. Patients with all types of cancer can be included in the study, if they have completed the therapy with chemo- and/or radiotherapy/surgery with curative intention and are expected to have a survival time >1 year. To determine the health-related quality of life the general questionnaire FACT G is used. The direct correlation between self-management and perceived self-efficacy is measured with the Jerusalem & Schwarzer questionnaire. Patients satisfaction with the care received is measured using the Patient Assessment of Chronic Illness Care 5 As (PACIC-5A. Data are collected at the beginning of the trial and after 3, 6 and 12 months. The power analysis revealed a sample size of 102 patients. The recruitment of the centres began in 2009. The inclusion of patients began in May 2010. Discussion Case management has proved to be effective regarding quality of life of patients with chronic diseases. When it comes to oncology, case management is mainly used in cancer treatment, but it is not yet common in the

    In preventing invasive fungal disease (IFD) in patients with acute myelogenous leukemia (AML) or myelodysplastic syndrome (MDS), clinical trials demonstrated efficacy of posaconazole over fluconazole and itraconazole. However, effectiveness of posaconazole has not been investigated in the United States in real-world setting outside the environment of controlled clinical trial. We performed a single-center, retrospective cohort study of 130 evaluable patients ≥18 years of age admitted to Duke University Hospital between 2004 and 2010 who received either posaconazole or fluconazole as prophylaxis during first induction or first reinduction chemotherapy for AML or MDS. The primary endpoint was possible, probable, or definite breakthrough IFD. Baseline characteristics were well balanced between groups, except that posaconazole recipients received reinduction chemotherapy and cytarabine more frequently. IFD occurred in 17/65 (27.0%) in the fluconazole group and in 6/65 (9.2%) in the posaconazole group (P = 0.012). Definite/probable IFDs occurred in 7 (10.8%) and 0 patients (0%), respectively (P = 0.0013). In multivariate analysis, fluconazole prophylaxis and duration of neutropenia were predictors of IFD. Mortality was similar between groups. This study demonstrates superior effectiveness of posaconazole over fluconazole as prophylaxis of IFD in AML and MDS patients. Such superiority did not translate to reductions in 100-day all-cause mortality. PMID:24644249

    Functional and molecular imaging has become increasingly used to evaluate interpatient and intrapatient tumor heterogeneity. Imaging allows for assessment of microenvironment parameters including tumor hypoxia, perfusion and proliferation, as well as tumor metabolism and the intratumoral distribution of specific molecular markers. Imaging information may be used to stratify patients for targeted therapies, and to define patient populations that may benefit from alternative therapeutic approaches. It also provides a method for non-invasive monitoring of treatment response at earlier time-points than traditional cues, such as tumor shrinkage. Further, companion diagnostic imaging techniques are becoming progressively more important for development and clinical implementation of targeted therapies. Imaging-based companion diagnostics are likely to be essential for the validation and FDA approval of targeted nanotherapies and macromolecular medicines. This review describes recent clinical advances in the use of functional and molecular imaging to evaluate the tumor microenvironment. Additionally, this article focuses on image-based assessment of distribution and anti-tumor effect of nano- and macromolecular systems.

    Breast cancer is the most common cancer in women. It can be diagnosed in early stage through screening, early detection and educational programs, and when diagnosed early it can be efficiently treated. Treatment modalities include surgery, chemotherapy, radiotherapy, hormonal therapy and targeted biologic therapy, according to the stage of the disease and patient condition. Treatment decisions should be made after multidisciplinary team discussion. Due to the significance of this disease it is important to define and implement standardized approach for diagnostic, treatment and monitoring algorithm as well. The following text presents the clinical guidelines in order to standardize the procedures and criteria for diagnosis, management, treatment and monitoring of patients with breast cancer in the Republic of Croatia.

    Microbes, as one of the primary producers of the biosphere, play an important role in ecosystems. Exploring the mechanism of adaptation and resistance of microbial population to various environmental factors has come into focus in the fields of modern microbial ecology and molecular ecology. However, facing the increasingly serious problem of acoustic pollution, very few efforts have been put forth into studying the relation of single cell organisms and sound field exposure. Herein, we studied the biological effects of sound exposure on the growth of E. coli K-12 with different acoustic parameters. The effects of sound exposure on the intracellular macromolecular synthesis and cellular morphology of E. coli K-12 were also analyzed and discussed. Experimental results indicated that E. coli K-12 exposed to sound waves owned a higher biomass and a faster specific growth rate compared to the control group. Also, the average length of E. coli K-12 cells increased more than 27.26%. The maximum biomass and maximum specific growth rate of the stimulation group by 8000 Hz, 80dB sound wave was about 1.7 times and 2.5 times that of the control group, respectively. Moreover, it was observed that E. coli K-12 can respond rapidly to sound stress at both the transcriptional and posttranscriptional levels by promoting the synthesis of intracellular RNA and total protein. Some potential mechanisms may be involved in the responses of bacterial cells to sound stress. PMID:27077011

    Pneumatosis intestinalis in children is associated with a wide variety of underlying conditions and often has a benign course. The CT features of this condition have not been systematically investigated. Defining benign pneumatosis intestinalis as pneumatosis intestinalis that resolved with medical management alone, we sought to: (1) determine whether the incidence of benign pneumatosis intestinalis had increased at our pediatric cancer hospital; (2) characterize CT features of benign pneumatosis intestinalis; and (3) determine the relationship between imaging features and clinical course of benign pneumatosis intestinalis in this cohort. Radiology reports from November 1994 to December 2006 were searched for ''pneumatosis intestinalis,'' ''free intraperitoneal air,'' and ''portal venous air or gas.'' Corresponding imaging was reviewed by two radiologists who confirmed pneumatosis intestinalis and recorded the presence of extraluminal free air, degree of intramural gaseous distension, number of involved bowel segments, and time to pneumatosis resolution. The search revealed 12 boys and 4 girls with pneumatosis intestinalis; 11 were hematopoietic stem cell transplant recipients. The annual incidences of benign pneumatosis have not changed at our institution. Increases in intramural distension marginally correlated with the number of bowel segments involved (P=0.08). Three patients had free air and longer times to resolution of pneumatosis (P=0.03). Male children may be at increased risk of benign pneumatosis intestinalis. The incidence of benign pneumatosis at our institution is proportional to the number of hematopoietic stem cell transplants. The degree of intramural distension may correlate with the number of bowel segments involved. Patients with free air have a longer time to resolution of benign pneumatosis. (orig.)

  8. K-12 Teacher Understanding of Energy Conservation: Conceptual Metaphor, Dissipation, and Degradation

    Science.gov (United States)

    Daane, Abigail R.

    In K-12 educational settings, conservation of energy is typically presented in two ways: the conservation of energy principle (energy is neither created nor destroyed) and the sociopolitical need to conserve energy (we guard against energy being used up). These two meanings of conservation typically remain disconnected from each other and can appear contradictory, even after instruction. In an effort to support teachers in building robust understandings of energy from their existing knowledge, I designed a study to investigate the productive ideas in K-12 teachers' conversations about energy. A micro-analysis of discourse, gestures, and artifacts of professional development courses revealed teachers' productive ideas about three aspects of energy: conceptual metaphor, dissipation and degradation. In learning about energy, K-12 teachers come to use conceptual metaphors in their own language and value attending to students' metaphorical language as a means of formative assessment. Teachers' conversations about dissipation suggest that apparent difficulties with energy conservation may have their roots in a strong association between forms of energy (thermal) and their perceptible indicators (warmth). Teachers address this challenge by employing an exaggeration strategy to locate the dissipated thermal energy, making the energy indicator perceptible. Finally, teachers' unprompted statements about sociopolitical aspects of energy are related to both statements from the NGSS and aspects of energy degradation. I conclude that energy conservation can be better taught and learned in K-12 Education by: 1) understanding and applying conceptual metaphors about energy in K-12 settings, 2) using prior experiences to better understand dissipative energy processes involving imperceptible thermal energy, thereby understanding how energy conservation applies in all situations, and 3) connecting productive ideas about sociopolitical aspects of energy to canonical physics.

    Full Text Available Abstract Background The purpose of this study is to assess the predictive accuracy of a multi-gene predictor of response to docetaxel, 5-fluorouracil, epirubicin and cyclophosphamide combination chemotherapy on gene expression data from patients who received these drugs as neoadjuvant treatment. Methods Tumor samples were obtained from patients with stage II-III breast cancer before starting neoadjuvant chemotherapy with four cycles of 5-fluorouracil/epirubicin/cyclophosphamide (FEC followed by four cycles of docetaxel/capecitabine (TX on US Oncology clinical trial 02-103. Most patients with HER-2-positive cancer also received trastuzumab (H. The chemotherapy predictor (TFEC-MGP was developed from publicly available gene expression data of 42 breast cancer cell-lines with corresponding in vitro chemotherapy sensitivity results for the four chemotherapy drugs. No predictor was developed for treatment with trastuzumab. The predictive performance of TFEC-MGP in distinguishing cases with pathologic complete response from those with residual disease was evaluated for the FEC/TX and FEC/TX plus H group separately. The area under the receiver-operating characteristic curve (AU-ROC was used as the metric of predictive performance. Genomic predictions were performed blinded to clinical outcome. Results The AU-ROC was 0.70 (95% CI: 0.57-0.82 for the FEC/TX group (n=66 and 0.43 (95% CI: 0.20-0.66 for the FEC/TX plus H group (n=25. Among the patients treated with FEC/TX, the AU-ROC was 0.69 (95% CI: 0.52-0.86 for estrogen receptor (ER-negative (n=28 and it was 0.59 (95% CI: 0.36-0.82 for ER-positive cancers (n=37. ER status was not reported for one patient. Conclusions Our results indicate that the cell line derived 291-probeset genomic predictor of response to FEC/TX combination chemotherapy shows good performance in a blinded validation study, particularly in ER-negative patients.

    Secretory otitis media (SOM) remains a common disease among children. Although its cause is not yet perfectly established, the pathology, often a sequel of acute otitis media (AOM), is mainly characterized by persistent fluid in the middle ear cavity. Twenty-two children with a diagnosis of SOM were treated daily for 90 days with an oral formulation containing the oral probiotic Streptococcus salivarius K12 (Bactoblis(®)). After treatment, the children were evaluated for AOM episodes and subjected to tone audiometry, tympanometry, endonasal endoscopy, otoscopy, and tonsillar examination. Subject compliance and probiotic tolerability and side effects have also been evaluated. Our results indicate a good safety profile, a substantial reduction of AOM episodes, and a positive outcome from the treatment for all of the clinical outcomes tested. We conclude that strain K12 may have a role in reducing the occurrence and/or severity of SOM in children. From our perspective, this study constitutes a starting point toward the organization of a more extensive placebo-controlled study aimed at critically appraising our preliminary observations.

    The debate is vigorous in psycho-oncology about whether spiritual, existential, and psychosocial are the most comprehensive terms for academic research discourses investigating meaning and purpose. A call-to-action email from the International Society of Psycho-Oncology included the term soul. The current essay highlights the historical and contemporary uses of "soul" to suggest that the re-emergent soul signifies a tacit quest for an "intangible" that seems missing in current constructs of clinical domains reflected in the vigor of the debates. It is suggested that the re-emergence of the pre-Medieval meaning(s) of the notion of soul affirms a growing need for integrative paradigms on "being human" to guide psycho-oncology practitioners and their research. As a paradigmatic example, a clinical support group entitled Soul Medicine is described as employing the term soul to open up the more marginal discourses about experiences of illness arising from philosophical reflection, arts, humanities, and spirituality within a clinical oncology context. A link between soul and wisdom is suggested for further exploration with the view that phronesis ("the virtue of practical wisdom"), an emerging concept in health professional education research, is of ultimate value to the people psycho-oncology seeks to serve. This group holds that garnering wisdom from the expertise of those living with cancer should be a central aim of our field.

    2016-01-01

    Oncology care is becoming increasingly complex. The interprofessional team concept of care is necessary to meet projected oncology professional shortages, as well as to provide superior oncology care. The oncology advanced practitioner (AP) is a licensed health care professional who has completed advanced training in nursing or pharmacy or has completed training as a physician assistant. Oncology APs increase practice productivity and efficiency. Proven to be cost effective, APs may perform varied roles in an oncology practice. Integrating an AP into an oncology practice requires forethought given to the type of collaborative model desired, role expectations, scheduling, training, and mentoring. PMID:27249776

    Streptococcus salivarius is naturally a predominant member of the human oropharynx and the commercial probiotic strain K12 has been consumed for more than a decade. The present study examines the health responses of human volunteers to oral ingestion of high doses of S. salivarius K12. A randomized group of 53 subjects received a dose of 1 × 10(10)cfu S. salivarius K12 (N=25) or placebo (N=28) for 28 days, followed by a 28-day wash out period. Blood, urine and saliva samples were collected at baseline and following treatment and analyzed, while the oral and gastrointestinal tolerance of the subjects to the dosing regimen was determined by use of questionnaires. Adverse events (AE)s were recorded for both groups. No statistically significant differences between the probiotic and placebo treated groups were detected in either the blood clinical chemistry or hematology results (P>0.05). The questionnaire responses of the subjects indicated that both treatments were well tolerated. The frequency and intensity of AEs was similar in the two groups. This data demonstrates that the daily ingestion of S. salivarius K12 over a 28-day period does not adversely affect the human host and supports the safety of its oral delivery in a food-based carrier.

    2004-12-01

    The Science, Technology, Engineering, and Mathematics Teacher Preparation (STEMTP) program at the University of Colorado has been designed to recruit and train prospective K-12 science teachers while improving student learning through interactive teaching. The program has four key goals: (1) recruit undergraduate students into K-12 science education, (2) provide these prospective teachers with hands-on experience in an interactive teaching pedagogy, (3) create an intergrated program designed to support (educationally, socially, and financially) and engage these prospective science teachers up until they obtain liscensure and/or their masters degree in education, and (4) improve student learning in large introductory science classes. Currently there are 31 students involved in the program and a total of 72 students have been involved in the year and a half it has been in existence. I will discuss the design of the STEMTP program, the success in recruiting K-12 science teachers, and the affect on student learning in a large lecture class of implementing interactive learning pedagogies by involving these prospective K-12 science teachers. J. L. Rosenberg would like to acknowledge the NSF Astronomy and Astrophysics Fellowship for support for this work.

    The Science Education Resource Center (SERC) has created a portal to information for K12 educators to provide high-quality grade level appropriate materials from a wide variety of projects and topics. These materials were compiled across the SERC site, showcasing materials that were created for, or easily adaptable to, K12 classrooms. This resource will help support implementation of Next Generation Science Standards by assisting educators in finding innovative resources to address areas of instruction that are conceptually different than previous national and state science standards. Specifically, the K12 portal assists educators in learning about approaches that address the cross-cutting nature of science concepts, increasing students quantitative reasoning and numeracy skills, incorporating technology such as GIS in the classroom, and by assisting educators of all levels of K12 instruction in using relevant and meaningful ways to teach science concepts. The K12 portal supports educators by providing access to hundreds of teaching activities covering a wide array of science topics and grade levels many of which have been rigorously reviewed for pedagogic quality and scientific accuracy. The portal also provides access to web pages that enhance teaching practices that help increase student's system thinking skills, make lectures interactive, assist instructors in conducting safe and effective indoor and outdoor labs, providing support for teaching energy and climate literacy principles, assisting educators in addressing controversial content, provide guidance in engaging students affective domain, and provides a collection of tools for making teaching relevant in 21st century classrooms including using GIS, Google Earth, videos, visualizations and simulations to model and describe scientific concepts.

    Kennedy Sheldon, Lisa; Brown, Carlton G

    2016-06-01

    This issue of the Clinical Journal of Oncology Nursing (CJON) will be the final time that you will see the Evidence-Based Practice (EBP) feature column. Why? Because we have seen oncology nursing evolve in the past 20 years and EBP is everywhere! We use it in our clinics and hospital units, incorporate it into decisions about symptom management, and use evidence to develop survivorship guidelines. We discuss EBP in journal clubs and use applications on mobile devices to find the best interventions for our patients. We have oncology nurses sitting on committees to develop guidelines based on the best evidence and expert opinion. We have come a long way and it is our belief that EBP is included in almost every article in CJON and, therefore, a need no longer exists for an individual column about EBP.

  5. Gamma camera based FDG PET in oncology

    International Nuclear Information System (INIS)

    Positron Emission Tomography(PET) was introduced as a research tool in the 1970s and it took about 20 years before PET became an useful clinical imaging modality. In the USA, insurance coverage for PET procedures in the 1990s was the turning point, I believe, for this progress. Initially PET was used in neurology but recently more than 80% of PET procedures are in oncological applications. I firmly believe, in the 21st century, one can not manage cancer patients properly without PET and PET is very important medical imaging modality in basic and clinical sciences. PET is grouped into 2 categories; conventional (c) and gamma camera based (CB) PET. CBPET is more readily available utilizing dual-head gamma cameras and commercially available FDG to many medical centers at low cost to patients. In fact there are more CBPET in operation than cPET in the USA. CBPET is inferior to cPET in its performance but clinical studies in oncology is feasible without expensive infrastructures such as staffing, rooms and equipments. At Ajou university Hospital, CBPET was installed in late 1997 for the first time in Korea as well as in Asia and the system has been used successfully and effectively in oncological applications. Our was the fourth PET operation in Korea and I believe this may have been instrumental for other institutions got interested in clinical PET. The following is a brief description of our clinical experience of FDG CBPET in oncology

  7. Radiation Oncology in Undergraduate Medical Education: A Literature Review

    International Nuclear Information System (INIS)

    Purpose: To review the published literature pertaining to radiation oncology in undergraduate medical education. Methods and Materials: Ovid MEDLINE, Ovid MEDLINE Daily Update and EMBASE databases were searched for the 11-year period of January 1, 1998, through the last week of March 2009. A medical librarian used an extensive list of indexed subject headings and text words. Results: The search returned 640 article references, but only seven contained significant information pertaining to teaching radiation oncology to medical undergraduates. One article described a comprehensive oncology curriculum including recommended radiation oncology teaching objectives and sample student evaluations, two described integrating radiation oncology teaching into a radiology rotation, two described multidisciplinary anatomy-based courses intended to reinforce principles of tumor biology and radiotherapy planning, one described an exercise designed to test clinical reasoning skills within radiation oncology cases, and one described a Web-based curriculum involving oncologic physics. Conclusions: To the authors' knowledge, this is the first review of the literature pertaining to teaching radiation oncology to medical undergraduates, and it demonstrates the paucity of published work in this area of medical education. Teaching radiation oncology should begin early in the undergraduate process, should be mandatory for all students, and should impart knowledge relevant to future general practitioners rather than detailed information relevant only to oncologists. Educators should make use of available model curricula and should integrate radiation oncology teaching into existing curricula or construct stand-alone oncology rotations where the principles of radiation oncology can be conveyed. Assessments of student knowledge and curriculum effectiveness are critical.

  10. Integrating Robot Design Competitions into the Curriculum and K-12 Outreach Activities

    Science.gov (United States)

    Avanzato, Robert

    The Penn State Abington campus has integrated several mobile robot design competitions into project-based design activities to provide enhancement for undergraduate engineering and information sciences and technology courses and also to provide outreach to K-12 institutions. The robot competitions, which encourage interdisciplinary design, teamwork, and rapid prototyping, support a wide range of educational outcomes in a variety of courses. A survey of undergraduate students was also implemented to identify the key lessons learned and overall educational quality of the robot competition activities. Overall, the responses on the quality of the robot competition experience were very positive. The strategic selection and implementation of robot design competitions, such as described in this paper, provide a cost-effective approach to enhancing the curriculum, promoting retention, and encouraging interest in science and technology (STEM) careers in K-12 students.

    2001-11-01

    Astronomy in grades K-12 is traditionally taught (if at all) using textbooks and a few simple hands-on activities. In addition, most students, by High School graduation, will never have even looked through the eyepiece of a telescope. The possibility now exists to establish a network of research grade telescopes, no longer useful to the professional astronomical community, that can be made accessible to schools all across the country through existing IT technologies and applications. These telescopes could provide unparalleled research and educational opportunities for a broad spectrum of K-12 and college students and turns underutilized observatory facilities into valuable, state-of-the-art teaching centers. The NASA-sponsored Telescopes In Education (TIE, http://tie.jpl.nasa.gov) project has been wildly successful in engaging the K-12 education community in real-time, hands-on, interactive astronomy activities. Hundreds of schools in the US, Australia, Canada, England, and Japan have participated in the TIE program, remotely controlling the 24-inch telescope at the Mount Wilson Observatory from their classrooms. In recent years, several (approximately 20 to date) other telescopes have been, or are in the process of being, outfitted for remote use as TIE affiliates. Global TIE integrates these telescopes seamlessly into one virtual observatory and provides the services required to operate this facility, including a scheduling service, tools for data manipulation, an online proposal review environment, an online "Virtual TIE Student Ap J" for publication of results, and access to related educational materials provided by the TIE community. Global TIE provides unparalleled research and educational opportunities for a broad spectrum of K-12 and college students and turns essentially unused observatory facilities into valuable, state-of-the-art teaching centers. This presentation describes the Global TIE Observatory data and organizational systems and details the

  2. Biochemical genetics of the cryptic gene system for cellobiose utilization in Escherichia coli K12.

    Science.gov (United States)

    Kricker, M; Hall, B G

    1987-03-01

    The cellobiose catabolic system of Escherichia coli K12 is being used to study the role of cryptic genes in microbial evolution. Wild-type E. coli K12 do not utilize the beta-glucoside sugars, arbutin, salicin and cellobiose. A Cel+ (cellobiose utilizing) mutant which grows on cellobiose, arbutin, and salicin was isolated previously from wild-type E. coli K12. Biochemical assays indicate that a cel structural gene (celT) specifies a single transport protein that is a beta-glucoside specific enzyme of the phosphoenolpyruvate-dependent phosphotransferase system. The transport protein phosphorylates beta-glucosides at the expense of phosphoenolpyruvate. A single phosphoglucosidase, specified by celH, hydrolyzes phosphorylated cellobiose, arbutin, and salicin. The genes of the cel system are expressed constitutively in the Cel+ mutant, whereas they are not expressed at a detectable level in the wild-type strain. The transport and hydrolase genes are simultaneously silenced or simultaneously expressed and thus constitute an operon. Cel+ strains which fail to utilize one or more beta-glucosides express the transport system at a lower level than do Cel+ strains which grow on all three beta-glucosides. Other strains inducibly express a gene which specifies transport of arbutin but not the other beta-glucosides. The arbutin transport gene, arbT, maps outside of the cel locus.

    It is appropriate that after almost half a century of Science and Mathematics education reform we take a look back and a peek forward to understand the present state of this wonderfully complex system. Each of the components of this system including teaching, professional development, assessment, content and the district K-12 curriculum all need to work together if we hope to provide quality science, mathematics and technology education for ALL students. How do the state and national standards drive the system? How do state policies on student testing and teacher licensure come into play? How do we improve the preparation, retention and job satisfaction of our K-12 teachers? What initiatives have made or are making a difference? What else needs to be done? What can the physics community do to support local efforts? This job is too big for any single organization or individual but we each can contribute to the effort. Our Center at Northeastern University, with support from the National Science Foundation, has a sharply defined focus: to get high quality, research-based instructional materials into the hands of K-12 classroom teachers and provide the support they need to use the materials effectively in their classrooms.

  4. Advanced Energy Retrofit Guide: Practical Ways to Improve Energy Performance, K-12 Schools (Book)

    Energy Technology Data Exchange (ETDEWEB)

    2013-12-01

    The U.S. Department of Energy developed the Advanced Energy Retrofit Guides (AERGs) to provide specific methodologies, information, and guidance to help energy managers and other stakeholders plan and execute energy efficiency improvements. Detailed technical discussion is fairly limited. Instead, we emphasize actionable information, practical methodologies, diverse case studies, and unbiased evaluations of the most promising retrofit energy efficiency measures for each building type. A series of AERGs is under development, addressing key segments of the commercial building stock. K-12 schools were selected as one of the highest priority building sectors, because schools affect the lives of most Americans. They also represent approximately 8% of the energy use and 10% of the floor area in commercial buildings nationwide. U.S. K-12 school districts spend more than $8 billion each year on energy - more than they spend on computers and textbooks combined. Most occupy older buildings that often have poor operational performance - more than 30% of schools were built before 1960. The average age of a school is about 42 years - which is nearly the expected serviceable lifespan of the building. K-12 schools offer unique opportunities for deep, cost-effective energy efficiency improvements, and this guide provides convenient and practical guidance for exploiting these opportunities in the context of public, private, and parochial schools.

  5. Environmental and genetic factors affecting mutability to aminoglycoside antibiotics among Escherichia coli K12 strains

    Directory of Open Access Journals (Sweden)

    Monteiro A.C.M.

    2003-01-01

    Full Text Available Environmental and genetic factors affecting the in vitro spontaneous mutation frequencies to aminoglycoside resistance in Escherichia coli K12 were investigated. Spontaneous mutation frequencies to kanamycin resistance were at least 100 fold higher on modified Luria agar (L2 plates, when compared to results obtained in experiments carried out with Nutrient agar (NA plates. In contrast to rifampincin, the increased mutability to kanamycin resistance could not be attributed to a mutator phenotype expressed by DNA repair defective strains. Kanamycin mutant selection windows and mutant preventive concentrations on L2 plates were at least fourfold higher than on NA plates, further demonstrating the role of growth medium composition on the mutability to aminoglycosides. Mutability to kanamycin resistance was increased following addition of sorbitol, suggesting that osmolarity is involved on the spontaneous mutability of E. coli K12 strains to aminoglycosides. The spontaneous mutation rates to kanamycin resistance on both L2 and NA plates were strictly associated with the selective antibiotic concentrations. Moreover, mutants selected at different antibiotic concentrations expressed heterogeneous resistance levels to kanamycin and most of them expressing multiple resistance to all tested aminoglycoside antibiotics (gentamicin, neomycin, amykacin and tobramycin. These results will contribute to a better understanding of the complex nature of aminoglycoside resistance and the emergence of spontaneous resistant mutants among E. coli K12 strains.

    The need for computing education in the K-12 curriculum has grown globally. The Republic of Korea is not an exception. In response to the need, the Korean Ministry of Education has announced an outline for software-centric computing education in the K-12 system, which aims at enhancing the current computing education with software emphasis. In this paper, we review the outline from a higher education perspective and provide insights into its constructive improvement based on our experience in computer science education in higher education and a study of global initiatives on computing education. We also consider the social environment for computing education in Korea. In the proposed implementation, we first discuss goals for software-centric computing education and identify areas of focus. The identified areas are discussed in terms of topics to be covered and appropriate exposure of knowledge depth in the three levels in the Korean K-12 system. We then discuss necessary preparations for the success of the plan from academic, governmental and social perspectives.

    Lymphography is often used for the diagnosis of lymphatic metastasis in oncology. Determination of lymphatic metastasis is extremely important for accurate cancer staging, which may directly guide the clinical therapeutic scheme. In recent years, the technology of lymphography has developed rapidly on the basis of traditional lymphography, with the appearance of com-puted tomography (CT) lymphography, nuclear magnetic resonance (MR) lymphography, contrast-enhanced lym-phosonography, and so on; the diagnostic accuracy has also been improved. The imaging principles and methods of these various technologies of lymphography are reviewed in this paper, and their applications and significance in oncology are also discussed in detail.

    Despite increasing numbers of cancer survivors, non-oncology physicians report discomfort and little training regarding oncologic and survivorship care. This pilot study assesses medical student comfort with medical oncology, surgical oncology, radiation oncology, hospice/palliative medicine, and survivorship care. A survey was developed with input from specialists in various fields of oncologic care at a National Cancer Institute-designated comprehensive cancer center. The survey included respondent demographics, reports of experience with oncology, comfort ratings with oncologic care, and five clinical vignettes. Responses were yes/no, multiple choice, Likert scale, or free response. The survey was distributed via email to medical students (MS1-4) at two US medical schools. The 105 respondents were 34 MS1s (32 %), 15 MS2s and MD/PhDs (14 %), 26 MS3s (25 %), and 30 MS4s (29 %). Medical oncology, surgical oncology, and hospice/palliative medicine demonstrated a significant trend for increased comfort from MS1 to MS4, but radiation oncology and survivorship care did not. MS3s and MS4s reported the least experience with survivorship care and radiation oncology. In the clinical vignettes, students performed the worst on the long-term chemotherapy toxicity and hospice/palliative medicine questions. Medical students report learning about components of oncologic care, but lack overall comfort with oncologic care. Medical students also fail to develop an increased self-assessed level of comfort with radiation oncology and survivorship care. These pilot results support development of a formalized multidisciplinary medical school oncology curriculum at these two institutions. An expanded national survey is being developed to confirm these preliminary findings.

    Systemic therapy is one of the cornerstones of cancer treatment. In 1972, following representations by American Society of Clinical Oncology (ASCO), the American Board of Internal Medicine (ABIM) recognized medical oncology as a new subspecialty of internal medicine. Subspecialty of Hematology and Medical Oncology was emerged in Iran in 1983. In the past, modern medical treatments and education were started in Dar Al-fonun school and then in Tehran University; now six universities in Iran are training in Subspecialty of Hematology and Medical Oncology. There are also ten active hematopoietic stem cell transplantation centers, thirty-one provincial medical schools use their specialized services. Future goals for Hematology and Medical Oncology in Iran include expansion and reinforcement of multidisciplinary teams across the country, early detection and prevention of cancer, providing educational program and conducting cancer researches. To achieve these goals, it is necessary to establish Cancer Hospitals in each province that link together through a network.

    Full Text Available The aim of this experimental study was to validate a psychophysical scale of languageperception and to rank the pain intensity associated to each one of the descriptors, verifying its consistency-reliability and inter-subjective agreement among professionals and patients. The research was held at the Clinics Hospital of Ribeirão Preto Medical School, from January to June, 2005, with 41 professionals and 20 patients. The pain descriptors were submitted to the analysis of psychophysical scale methods in a single method of category and magnitude estimation. The pain for the professionals of a Gynecologic Oncology service was referred as pungent, thin and piercing and for the patients, as cutting and burning. On the Pediatric Oncology, the professionals expressed the pain as pungent, thin and burning, while the patients as burning; compressive, persistent and piercing. By Spearman’s correlation (0,713, it was demonstrated that there is a high correlation among the doctors. Concerning to magnitude estimation, a high correlation between doctors and nurses (0,871 was verified. It was evidenced by the study that the correlation analyses suggest that the magnitude of different describers, associated to the displeasure of the pain judged by the patients, differ of those referred by different health professionals.

  19. Sense and Sensibility: The Case for the Nationwide Inclusion of Engineering in the K-12 Curriculum

    Science.gov (United States)

    Lindberg, Robert E.; Pinelli, Thomas E.; Batterson, James G.

    2008-01-01

    The competitive status of the United States is inextricably linked to innovation just as innovation is inseparable from science, technology, engineering, and mathematics. To stay competitive in innovation requires that the United States produce a 21st century workforce complete with requisite education, training, skills, and motivation. If we accept a priori that science, technology, engineering, and mathematics education are crucial to competitiveness and innovation and that, in terms of innovation, mathematics, science, and engineering are interdependent, why are mathematics and science uniformly ubiquitous in the K-12 curriculum while engineering is conspicuously absent? We are passionate in our belief that the uniform addition of engineering to the K-12 curriculum will help ensure that the nation has "the right" 21st Century workforce. Furthermore, we believe that a nationwide effort, led by a coalition of engineering academics, practitioners, and societies is required to turn this goal into reality. However, accomplishing this goal necessitates, as we are reminded by the title of Jane Austen's timeless novel, "Sense and Sensibility", a workable solution that seeks the "middle ground" between passion and reason. We begin our paper by making two essential points: Engineers are not scientists. Engineering exists separate from science, has its own specialized knowledge community apart from science, and it is largely responsible for many of the most significant advancements and improvements in the quality of our life. Our workable solution requires that K-12 education, nationwide, accommodate the inclusion of engineering as a stand alone curriculum and we offer three reasons to support our position: (1) workforce development, (2) stimulating interest in STEM (science, technology, engineering, and mathematics) courses and careers, and (3) creating a technologically literate society. We conclude with some thoughts on how this important goal can be accomplished.

    Scientists are very interested in the formation of contrails, both the type and the coverage. To be detected by a satellite-born instrument, the contrail must be of a certain size, which means that some contrails go undetected. The K-12 education community is assisting with the study of contrails by participating in a network of student observers. To provide a venue for student contrail observations, the GLOBE Contrails protocol was developed as part of the GLOBE Atmospheric Science protocols. The first year of observations has provided a rich resource for researcher.

    Di Pierro, Francesco; Colombo, Maria; Zanvit, Alberto; Risso, Paolo; Rottoli, Amilcare S

    2014-01-01

    Background Streptococcus salivarius K12 is an oral probiotic strain releasing two lantibiotics (salivaricin A2 and salivaricin B) that antagonize the growth of S. pyogenes, the most important bacterial cause of pharyngeal infections in humans also affected by episodes of acute otitis media. S. salivarius K12 successfully colonizes the oral cavity, and is endowed with an excellent safety profile. We tested its preventive role in reducing the incidence of both streptococcal and viral pharyngitis and/or tonsillitis in children. Materials and methods We enrolled 61 children with a diagnosis of recurrent oral streptococcal disorders. Thirty-one of them were enrolled to be treated daily for 90 days with a slow-release tablet for oral use, containing no less than 1 billion colony-forming units/tablet of S. salivarius K12 (Bactoblis®), and the remaining 30 served as the untreated control group. During treatment, they were all examined for streptococcal infection. Twenty children (ten per group) were also assessed in terms of viral infection. Secondary end points in both groups were the number of days under antibiotic and antipyretic therapy and the number of days off school (children) and off work (parents). Results The 30 children who completed the 90-day trial with Bactoblis® showed a significant reduction in their episodes of streptococcal pharyngeal infection (>90%), as calculated by comparing the infection rates of the previous year. No difference was observed in the control group. The treated group showed a significant decrease in the incidence (80%) of oral viral infections. Again, there was no difference in the control group. With regard to secondary end points, the number of days under antibiotic treatment of the treated and control groups were 30 and 900 respectively, days under antipyretic treatment 16 and 228, days of absence from school 16 and 228, and days of absence from work 16 and 228. The product was well tolerated by the subjects, with no side effects

    2004-01-01

    A reconnaissance study of the geology professional development program known as RockCamp was initiated to examine the sustained, or recurrent, participation of K-12 science teachers. Open-ended interviews, concept mapping, and creative writing assignments were used to explore the perceptions of six teachers possessing an exceptional record of participation. Efficacy, fun, right time of life, and support emerged as unanimous reasons for recurrent participation. Content, friendship, and methodology were very important. College credit was not critical. These teachers' perceptions suggest their sustained involvement in the RockCamp Program is stimulated by situated learning experiences stressing a compare, contrast, connect, and construct pedagogy within a supportive learning community.

  4. MUST ONCOLOGICAL PRINCIPLES BE IN THE SURGERY OF MENINGIOMAS? EN BLOC REMOVAL OF GIANT RIGHT FRONTAL MENINGIOMA WITH EXTRACRANIAL SPREAD. DESCRIPTION OF A CLINICAL CASE

    Directory of Open Access Journals (Sweden)

    V. B. Karakhan

    2014-01-01

    Full Text Available The use of the oncological principle – en bloc ablastic tumor resection – can expect a breakthrough in the treatment of baseline unfavorable patient groups. In the described case of atypical meningioma, its en bloc resection presents significant technical difficulties when accomplishing the task associated with the giant sizes of a tumor as an iceberg growing outside and into the cranial cavity, its rich vascularization from both the internal and external carotid artery system, with the involvement of the superior sagittal sinus, the presence of a dense bone crown that combines the three-component construction of a neoplasm, which made difficult safe mobilization and scanning in the cranial cavity.In such topographic variants, the criteria for the Simpson radical meningioma resection are inapplicable and only en bloc tumor resection may reflect the oncological principles of surgery. The technologies of en bloc resection of intracranial meningiomas should be more frequently used because preoperative neurovisualization and even histological diagnosis does not always allow the grade of meningiomas to be specified.

  6. A Research Agenda for Radiation Oncology: Results of the Radiation Oncology Institute’s Comprehensive Research Needs Assessment

    International Nuclear Information System (INIS)

    Purpose: To promote the rational use of scarce research funding, scholars have developed methods for the systematic identification and prioritization of health research needs. The Radiation Oncology Institute commissioned an independent, comprehensive assessment of research needs for the advancement of radiation oncology care. Methods and Materials: The research needs assessment used a mixed-method, qualitative and quantitative social scientific approach, including structured interviews with diverse stakeholders, focus groups, surveys of American Society for Radiation Oncology (ASTRO) members, and a prioritization exercise using a modified Delphi technique. Results: Six co-equal priorities were identified: (1) Identify and develop communication strategies to help patients and others better understand radiation therapy; (2) Establish a set of quality indicators for major radiation oncology procedures and evaluate their use in radiation oncology delivery; (3) Identify best practices for the management of radiation toxicity and issues in cancer survivorship; (4) Conduct comparative effectiveness studies related to radiation therapy that consider clinical benefit, toxicity (including quality of life), and other outcomes; (5) Assess the value of radiation therapy; and (6) Develop a radiation oncology registry. Conclusions: To our knowledge, this prioritization exercise is the only comprehensive and methodologically rigorous assessment of research needs in the field of radiation oncology. Broad dissemination of these findings is critical to maximally leverage the impact of this work, particularly because grant funding decisions are often made by committees on which highly specialized disciplines such as radiation oncology are not well represented.

    Purpose: The aim of this study was to report on the development of a standardized target and organ-at-risk naming convention for use in radiation therapy and to present the nomenclature for structure naming for interinstitutional data sharing, clinical trial repositories, integrated multi-institutional collaborative databases, and quality control centers. This taxonomy should also enable improved plan benchmarking between clinical institutions and vendors and facilitation of automated treatment plan quality control. Materials and Methods: The Advanced Technology Consortium, Washington University in St. Louis, Radiation Therapy Oncology Group, Dutch Radiation Oncology Society, and the Clinical Trials RT QA Harmonization Group collaborated in creating this new naming convention. The International Commission on Radiation Units and Measurements guidelines have been used to create standardized nomenclature for target volumes (clinical target volume, internal target volume, planning target volume, etc.), organs at risk, and planning organ-at-risk volumes in radiation therapy. The nomenclature also includes rules for specifying laterality and margins for various structures. The naming rules distinguish tumor and nodal planning target volumes, with correspondence to their respective tumor/nodal clinical target volumes. It also provides rules for basic structure naming, as well as an option for more detailed names. Names of nonstandard structures used mainly for plan optimization or evaluation (rings, islands of dose avoidance, islands where additional dose is needed [dose painting]) are identified separately. Results: In addition to its use in 16 ongoing Radiation Therapy Oncology Group advanced technology clinical trial protocols and several new European Organization for Research and Treatment of Cancer protocols, a pilot version of this naming convention has been evaluated using patient data sets with varying treatment sites. All structures in these data sets were

    Marianne R F Bosscher

    Full Text Available For some oncologic emergencies, surgical interventions are necessary for dissolution or temporary relieve. In the absence of guidelines, the most optimal method for decision making would be in a multidisciplinary cancer conference (MCC. In an acute setting, the opportunity for multidisciplinary discussion is often not available. In this study, the management and short term outcome of patients after surgical oncologic emergency consultation was analyzed.A prospective registration and follow up of adult patients with surgical oncologic emergencies between 01-11-2013 and 30-04-2014. The follow up period was 30 days.In total, 207 patients with surgical oncologic emergencies were included. Postoperative wound infections, malignant obstruction, and clinical deterioration due to progressive disease were the most frequent conditions for surgical oncologic emergency consultation. During the follow up period, 40% of patients underwent surgery. The median number of involved medical specialties was two. Only 30% of all patients were discussed in a MCC within 30 days after emergency consultation, and only 41% of the patients who underwent surgery were discussed in a MCC. For 79% of these patients, the surgical procedure was performed before the MCC. Mortality within 30 days was 13%.In most cases, surgery occurred without discussing the patient in a MCC, regardless of the fact that multiple medical specialties were involved in the treatment process. There is a need for prognostic aids and acute oncology pathways with structural multidisciplinary management. These will provide in faster institution of the most appropriate personalized cancer care, and prevent unnecessary investigations or invasive therapy.

    Nakayama, H.

    1975-01-01

    The cell lethality and DNA fragmentation caused by phleomycin (PM) were studied in E. coli K12 strains with special reference to the effects of repair or recombination deficiencies and metabolic inhibitors. Unlike excision-defective derivatives of E. coli B, uvrA, uvrB, and uvrC mutants of strain K12 showed no peculiarities compared with wild type in regard to cell survival. Likewise, mutant alleles at uvrD and polA loci had no effect. In contrast, rec mutants were more sensitive to PM-killing than were rec/sup +/ strains. PM-induced strand breakage in DNA was observed in all strains tested including the above-mentioned mutants. There was no significant distinction between the uvr mutants and the wild type strain, indicating that the uvr-endonuclease was not responsible for the strand breaks. Involvement of endonuclease I was also ruled out. At least some of the PM-induced strand breaks were repairable. PM-induced lethality and strand breakage were totally dependent on energy supply. Inhibition of protein synthesis resulted in a partial and parallel suppression of the two effects. Our results suggest that the lethality is due to DNA strand breakage and the repair of such damage is postulated to be controlled by rec genes.

    The newly-released Next Generation Science Standards (NGSS) have been under development for a few years with broad community input and explicit involvement of many states likely to adopt these as their own science standards. Several key features of the NGSS make these a substantial advance from the existing National Science Education Standards (NRC 1996), including focus on three dimensions previously outlined in A Framework for K-12 Science Education (NRC 2011): Science and Engineering Practices; Cross-cutting Concepts; and Disciplinary Core Ideas. What are the implications of all this now for K-12 educators, in the immediate term and in the long-term? What do the NGSS imply for EPO professionals, especially those involved in science curriculum development and teacher professional development? What should higher education faculty know about the NGSS, especially as it relates to the preparation of incoming college students, as well as the education of future elementary and secondary science teachers in college (including in Astro 101-type courses)?

    Keller, T.

    2010-12-01

    The National Academy of Sciences has created a committee of 18 National Academy of Science and Engineering members, academic scientists, cognitive and learning scientists, and educators, educational policymakers and researchers to develop a framework to guide new K-12 science education standards. The committee began its work in January, 2010, released a draft of the framework in July, 2010, and intends to have the final framework in the first quarter of 2011. The committee was helped in early phases of the work by consultant design teams. The framework is designed to help realize a vision for science and engineering education in which all students actively engage in science and engineering practices in order to deepen their understanding of core ideas in science over multiple years of school. These three dimensions - core disciplinary ideas, science and engineering practices, and cross-cutting elements - must blend together to build an exciting, relevant, and forward looking science education. The framework will be used as a base for development of next generation K-12 science education standards.

  13. A qualitative assessment of preservice elementary teachers' formative perceptions regarding engineering and K-12 engineering education

    Science.gov (United States)

    Culver, Dennis Eugene

    Current teacher education programs provide limited instruction for preservice elementary teachers regarding the incorporation or teaching of engineering concepts and skills in their classrooms. Few studies have been conducted that focus specifically on preservice elementary teachers' formative perceptions and receptivity towards engineering education. That is, not enough is known about what preservice teachers know and think about engineering. The purpose of this qualitative research study was to investigate how forty-four preservice elementary teachers' from a large Midwestern university approached engineering design, the perceptions of engineering and K-12 engineering education that they possessed, and their level of receptiveness with regards to K-12 engineering education. Data were collected using a demographic survey, journal entries, observations, and focus group discussions. The written, verbal, and visual data collected in this study were analyzed using conventional qualitative content analysis, which consisted of inductively developing categories and codes after repeatedly examining the data. The results of the study indicate that the preservice elementary teachers did not utilize any deliberate design process when engaged in a design task. Engineering was perceived as being synonymous with construction and that engineering design consists of trial and error. Participants envisioned their students succeeding in engineering due to their students' prior knowledge, not necessarily the actions of themselves as the teacher. With regards to receptivity, participants expressed apprehension and optimism along with fear and pessimism. Tangential factors also impacted the receptivity of participants.

    2015-11-01

    Full Text Available The history education literature is replete with a call to help teachers understand that history should be taught as being inquiry-based and interpretive. We are encouraged, and rightfully so, to do history, to perform history, to do democracy, and to motivate students for inquiry and action by using primary sources. The authors developed a unit of study for history and social studies teacher candidates that would address several issues: (a motivate and inspire future teachers to use inquiry as a tool to build K-12 students’ historical understanding and facilitate purposeful utilization of artifacts with ease; (b help future teachers increase their knowledge of local history; and (c present a unit that could be easily used in a secondary history course and, with some modifications, could be adapted for elementary and middle school history classrooms. The assignment was named Pay it Forward: Invigorating Instruction through Local History. This multifaceted assignment included the development of a lesson plan that would (a demonstrate a robust understanding of engaging students in historical inquiry and local history, and (b focus on an artifact that the teacher candidate would find as part of the investigation. The majority of the teacher candidates in this study did show evidence of, albeit limited at times, designing curriculum that encouraged K-12 students to engage in historical inquiry. Making the bridge between theory and practice, or showing evidence of learning from the methods courses, was clearly evident across the lesson plans.

    International Nuclear Information System (INIS)

    The movement to improve healthcare quality has led to a need for carefully designed quality indicators that accurately reflect the quality of care. Many different measures have been proposed and continue to be developed by governmental agencies and accrediting bodies. However, given the inherent differences in the delivery of care among medical specialties, the same indicators will not be valid across all of them. Specifically, oncology is a field in which it can be difficult to develop quality indicators, because the effectiveness of an oncologic intervention is often not immediately apparent, and the multidisciplinary nature of the field necessarily involves many different specialties. Existing and emerging comparative effectiveness data are helping to guide evidence-based practice, and the increasing availability of these data provides the opportunity to identify key structure and process measures that predict for quality outcomes. The increasing emphasis on quality and efficiency will continue to compel the medical profession to identify appropriate quality measures to facilitate quality improvement efforts and to guide accreditation, credentialing, and reimbursement. Given the wide-reaching implications of quality metrics, it is essential that they be developed and implemented with scientific rigor. The aims of the present report were to review the current state of quality assessment in oncology, identify existing indicators with the best evidence to support their implementation, and propose a framework for identifying and refining measures most indicative of true quality in oncologic care.

S. salivarius K12 successfully colonizes the oral cavity, and is endowed with an excellent safety profile. We tested its preventive role in reducing the incidence of both streptococcal and viral pharyngitis and/or tonsillitis in children. Materials and methods: We enrolled 61 children with a diagnosis of recurrent oral streptococcal disorders. Thirty-one of them were enrolled to be treated daily for 90 days with a slow-release tablet for oral use, containing no less than 1 billion colony-forming units/tablet of S. salivarius K12 (Bactoblis®, and the remaining 30 served as the untreated control group. During treatment, they were all examined for streptococcal infection. Twenty children (ten per group were also assessed in terms of viral infection. Secondary end points in both groups were the number of days under antibiotic and antipyretic therapy and the number of days off school (children and off work (parents. Results: The 30 children who completed the 90-day trial with Bactoblis® showed a significant reduction in their episodes of streptococcal pharyngeal infection (>90%, as calculated by comparing the infection rates of the previous year. No difference was observed in the control group. The treated group showed a significant decrease in the incidence (80% of oral viral infections. Again

    We show that the metY locus which specifies tRNA(2fMet) in Escherichia coli K-12 specifies tRNA(1fMet) in E. coli B. This conclusion is based on results of Southern blot analysis of E. coli B and K-12 DNAs and on polymerase chain reaction amplification, cloning, and sequencing of an approximately 200-bp region of DNA corresponding to the metY loci of E. coli B and E. coli K-12. We also show that the metY locus of E. coli B is transcriptionally active. E. coli strains transformed with the mult...

  19. Quality of life in oncology with emphasis upon neuro-oncology.

    Science.gov (United States)

    Choucair, Ali K

    2007-01-01

    Quality of life, as a science has been steadily gaining importance in both clinical practice as well as research. Despite major progress in the development of validated and clinically-relevant health-related quality of life (HRQOL) measures, we still face many challenges in bridging the gap between what we know and how to apply it in clinical practice: in making the transfer from the mere collection of QOL data to its utilization in improving patient outcome through interventional symptomatic therapy. This manuscript traces the development of QOL as a science to its potential utility in both clinical care and clinical research, as well as an outcomes measure. The emphasis has been placed upon quality of life in oncology with special attention to neuro-oncology. PMID:17127306

  6. A Mixed-Method Approach on Digital Educational Games for K12: Gender, Attitudes and Performance

    Science.gov (United States)

    Law, Effie Lai-Chong; Gamble, Tim; Schwarz, Daniel; Kickmeier-Rust, Michael D.; Holzinger, Andreas

    Research on the influence of gender on attitudes towards and performance in digital educational games (DEGs) has quite a long history. Generally, males tend to play such games more engagingly than females, consequently attitude and performance of males using DEGs should be presumably higher than that of females. This paper reports an investigation of a DEG, which was developed to enhance the acquisition of geographical knowledge, carried out on British, German and Austrian K12 students aged between 11 and 14. Methods include a survey on initial design concepts, user tests on the system and two single-gender focus groups. Gender and cultural differences in gameplay habit, game type preferences and game character perceptions were observed. The results showed that both genders similarly improved their geographical knowledge, although boys tended to have a higher level of positive user experience than the girls. The qualitative data from the focus groups illustrated some interesting gender differences in perceiving various aspects of the game.

  7. Code to Learn: Where Does It Belong in the K-12 Curriculum?

    2016-06-01

    Full Text Available The introduction of computer programming in K-12 has become mainstream in the last years, as countries around the world are making coding part of their curriculum. Nevertheless, there is a lack of empirical studies that investigate how learning to program at an early age affects other school subjects. In this regard, this paper compares three quasi-experimental research designs conducted in three different schools (n=129 students from 2nd and 6th grade, in order to assess the impact of introducing programming with Scratch at different stages and in several subjects. While both 6th grade experimental groups working with coding activities showed a statistically significant improvement in terms of academic performance, this was not the case in the 2nd grade classroom. Notable disparity was also found regarding the subject in which the programming activities were included, as in social studies the effect size was double that in mathematics.

  8. Achieving 50% Energy Savings in New Schools, Advanced Energy Design Guides: K-12 Schools (Brochure)

    Energy Technology Data Exchange (ETDEWEB)

    2014-09-01

    This fact sheet summarizes recommendations for designing elementary, middle, and high school buildings that will result in 50% less energy use than conventional new schools built to minimum code requirements. The recommendations are drawn from the Advanced Energy Design Guide for K-12 School Buildings, an ASHRAE publication that provides comprehensive recommendations for designing low-energy-use school buildings (see sidebar). Designed as a stand-alone document, this fact sheet provides key principles and a set of prescriptive design recommendations appropriate for smaller schools with insufficient budgets to fully implement best practices for integrated design and optimized performance. The recommendations have undergone a thorough analysis and review process through ASHRAE, and have been deemed the best combination of measures to achieve 50% savings in the greatest number of schools.

    2004-03-01

    Teacher professional development is accepted as a key ingredient in the support and improvement of K-12 science education nationwide. Since 1993 Montana State University-Bozeman has operated a large-scale experimental program in online science instruction designed specifically for in-service teachers. With NSF support, MSU's National Teachers Enhancement Network (NTEN) has delivered courses to over 7000 enrollees in all 50 states and beyond, using a delivery model that emphasizes student interactivity and the connections between science understanding and classroom practice. Although NTEN offers courses in a wide range of science areas, physics and astronomy have been the strongest focus. As well as providing an overview of the project, we will discuss strengths and difficulties in this form of instruction, based on participant feedback, studies by the project's external evaluation team, and a decade of personal experience. We will also comment on potential impacts of NCLB on the future of such efforts. *Supported by NSF Grant TE0101985

  10. Survey on Teaching Science to K-12 Students with Disabilities: Teacher Preparedness and Attitudes

    Kahn, Sami; Lewis, Anna R.

    2014-12-01

    Students with disabilities are increasingly included in general education science classrooms and are expected to demonstrate academic proficiency on standardized assessments. Teacher preparation and attitudes have been cited as major factors contributing to either the success or failure of students with disabilities in science. In order to assess the current state of what could be facilitative or inhibitory influences, a national online survey to which 1,088 K-12 science teachers responded was conducted. Mixed methods' analyses suggest that science teachers receive little formal training and feel underprepared to teach students with disabilities. Results identify specific gaps in science teachers' education, as well as attitudinal and institutional barriers that may inhibit students with disabilities' success. However, science teachers remain highly receptive to training and collaboration. Implications for science teacher education are discussed.

    2003-10-01

    A plasmid pSDK-1 containing the Escherichia coli phosphofructokinase-1 (EC 2.7.1. 11) gene (pfkA) was constructed and transferred into Acidithiobacillus thiooxidans Tt-Z2 by conjugation. The transfer frequency of plasmid from E. coli to Tt-Z2 was 2.6 x 10(-6). More than 68% of Tt-Z2 cells carried the recombinant plasmids after being cultured for 50 generations without selective pressure, which showed that pSDK-1 was maintained consistently in Tt-Z2. The pfkA gene from E. coli could be expressed in this obligately autotrophic bacterium but the enzyme activity (14 U/g was lower than that in E. coli (K-12: 86 U/g; DF1010 carrying plasmid pSDK-1: 97 U/g). In th presence of glucose, the Tt-Z2 transconjugant consumed glucose leading to a better growth yield.

  12. Assessment lessons from K-12 education research: Knowledge representation, learning, and motivation

    Shepard, Lorrie A.

    2012-02-01

    Research on teaching to the test in K-12 settings has documented the lack of generalized understanding of underlying principles in tested subjects. This is similar to the experience of physics students who can complete computational problems without conceptual understanding. The PER community is well aware of the importance of explicit representations of learning goals as well as the role of the formative assessment process, especially feedback and self assessment, in promoting or deterring students' engagement and willingness to take responsibility for their own learning. Key principles from socio-cultural learning theory and research on motivation are summarized and used to identify instructional and assessment practices that hold the most promise for engaging students in developing deep conceptual understanding.

    2005-12-01

    Minnesota has a reputation for excellence in K-12 science education. When the Minnesota Legislature required new academic standards in science, the state became an attractive venue for advocates of creationism and intelligent design who were intent on parallel teaching of evolution and what they refer to as "the" alternative. This paper describes the strategies used by a well-organized movement to include ID in the science standards and provides a case study/example of the so-called Wedge Strategy from the perspective of scientists who served as members of the MN science standards committee. The paper discusses the critial role scientists played in the development of exemplary and rigorous Earth science standards now legislated in MN and concludes with recommendations for the geoscience community derived from the experiences of geoscientists and educators who served as "reluctant warriors" in the battle for standards-based geoscience education in MN and Ohio.

    DNA sequence and expressional analyses of the gcd gene of Escherichia coli K-12 W3110 revealed that two promoters that were detected were regulated negatively by cyclic AMP and positively by oxygen. Sequence conservation of the gcd gene between E. coli K-12 W3110 and PPA42 suggests that glucose dehydrogenase is required for the E. coli cells, even though it ordinarily exists as an apoprotein.

    2015-02-01

    Interventional oncology is an evolving branch of interventional radiology, which relies on rapidly evolving, highly sophisticated treatment tools and precise imaging guidance to target and destroy malignant tumours. The development of this field has important potential benefits for patients and the health-care system, but as a new discipline, interventional oncology has not yet fully established its place in the wider field of oncology; its application does not have a comprehensive evidence base, or a clinical or quality-assurance framework within which to operate. In this regard, radiation oncology, a cornerstone of modern cancer care, has a lot of important information to offer to interventional oncologists. A strong collaboration between radiation oncology and interventional oncology, both of which aim to cure or control tumours or to relieve symptoms with as little collateral damage to normal tissue as possible, will have substantial advantages for both disciplines. A close relationship with radiation oncology will help facilitate the development of a robust quality-assurance framework and accumulation of evidence to support the integration of interventional oncology into multidisciplinary care. Furthermore, collaboration between interventional oncology and radiation oncology fields will have great benefits to practitioners, people affected by cancer, and to the wider field of oncology.

    2016-01-01

    Safety concerns may arise from a lack of standardization and ambiguity during the treatment planning and delivery process in radiation therapy. A standardized target and organ-at-risk naming convention in radiation therapy was developed by a task force comprised of several Radiation Oncology Societies. We present a nested-survey approach in a community setting to determine the methodology for radiation oncology departments to standardize their practice. Our Institution's continuous quality improvement (CQI) committee recognized that, due to growth from one to three centers, significant variability existed within plan parameters specific to patients' treatment. A multidiscipline, multiclinical site consortium was established to create a guideline for standard naming. Input was gathered using anonymous, electronic surveys from physicians, physicists, dosimetrists, chief therapists, and nurse managers. Surveys consisted of several primary areas of interest: anatomical sites, course naming, treatment plan naming, and treatment field naming. Additional concepts included capitalization, specification of laterality, course naming in the event of multiple sites being treated within the same course of treatment, primary versus boost planning, the use of bolus, revisions for plans, image-guidance field naming, forbidden characters, and standard units for commonly used physical quantities in radiation oncology practice. Guidelines for standard treatment naming were developed that could be readily adopted. This multidisciplinary study provides a clear, straightforward, and easily implemented protocol for the radiotherapy treatment process. Standard nomenclature facilitates the safe means of communication between team members in radiation oncology. The guidelines presented in this work serve as a model for radiation oncology clinics to standardize their practices. PMID:27074449

    Radiation therapy is an effective, personalized cancer treatment that has benefited from technological advances associated with the growing ability to identify and target tumors with accuracy and precision. Given that these advances have played a central role in the success of radiation therapy as a major component of comprehensive cancer care, the American Society for Radiation Oncology (ASTRO), the American Association of Physicists in Medicine (AAPM), and the National Cancer Institute (NCI) sponsored a workshop entitled "Technology for Innovation in Radiation Oncology," which took place at the National Institutes of Health (NIH) in Bethesda, Maryland, on June 13 and 14, 2013. The purpose of this workshop was to discuss emerging technology for the field and to recognize areas for greater research investment. Expert clinicians and scientists discussed innovative technology in radiation oncology, in particular as to how these technologies are being developed and translated to clinical practice in the face of current and future challenges and opportunities. Technologies encompassed topics in functional imaging, treatment devices, nanotechnology, and information technology. The technical, quality, and safety performance of these technologies were also considered. A major theme of the workshop was the growing importance of innovation in the domain of process automation and oncology informatics. The technologically advanced nature of radiation therapy treatments predisposes radiation oncology research teams to take on informatics research initiatives. In addition, the discussion on technology development was balanced with a parallel conversation regarding the need for evidence of efficacy and effectiveness. The linkage between the need for evidence and the efforts in informatics research was clearly identified as synergistic.

  3. The clinical value of combined use of MR imaging and multi-slice spiral CT in limb salvage surgery for orthopaedic oncology patients: initial experience in nine patients

    International Nuclear Information System (INIS)

    The purpose of this prospective study was to evaluate the value of the combined use of MR imaging and multi-slice spiral CT for limb salvage surgery in orthopaedic oncology patients. Nine consecutive patients with lower/upper limb malignant bone tumours (7 osteosarcomas and 2 chondrosarcomas) were treated with limb-salvaging procedures. Preoperative planning including determination of the osteotomy plane and diameters of the prosthesis was performed basing on the preoperative CT and MR images. The histopathology was performed as golden diagnostic criteria to evaluate the accuracy of CT and MR-based determination for tumour’s boundary. The tumour extension measured on MRI was consistent with the actual extension (P>0.05, paired Student’s t test), while the extension measured on CT imaging was less than the actual extension. The length, offset and alignment of the affected limb were reconstructed accurately after the operation. An excellent functional outcome was achieved in all patients. In the present study, MRI was found to be superior to CT for determining the tumour extension, combined use of MRI and CT measurement provided high precision for the fit of the prosthesis and excellent functional results

    The American Meteorological Society (AMS) DataStreme Project is a free professional development program for in-service K-12 teachers, in which they gain considerable subject matter content and confidence in Earth science instruction. DataStreme Atmosphere, Ocean, and Earth's Climate System (ECS) are offered each fall and spring semester by Local Implementation Teams (LITs) across the country in coordination with a team of AMS Education Program scientists and educators who develop instructional materials, provide logistical support to the LITs, and administer the project. The 3-member LITs mentor about 8 teachers and in some instances an emergency manager, per semester through a given DataStreme course. Teachers may receive 3 tuition-free graduate credits through State University of New York's The College at Brockport upon completion of each DataStreme course. DataStreme is in close alignment with A Framework for K-12 Science Education and the Next Generation Science Standards (NGSS). Investigating the scientific basis of the workings of Earth's atmosphere, ocean, and climate system follows the cross-cutting theme of the Framework and the NGSS and is the cornerstone of the DataStreme courses. In particular, DataStreme ECS explores the fundamental science of Earth's climate system and addresses the societal impacts relevant to today's teachers and students. The course utilizes resources from respected organizations, such as the IPCC and U.S. Global Change Research Program. Key to the NGSS is that students learn disciplinary core ideas in the context of science and engineering practices. In order for the students to learn in this way, the AMS believes that it is important to train the teachers in this context. DataStreme ECS emphasizes investigation of real-word and current NASA and NOAA data. Participants also are made aware of NASA's EdGCM, a research-grade Global Climate Model where they can explore various future climate scenarios in the same way that actual

    The K-12 science teacher is always seeking ways of improving and updating their curriculum by integrating the latest research into their most effective classroom activities. However, the daily demands of delivering instruction to large numbers of students coupled with the rapid advances in some fields of science can often overwhelm this effort. The NSF-sponsored Cataclysms and Catastrophes curriculum, developed by scientists from the The University of Texas at Austin Institute for Geophysics (UTIG) and Bureau of Economic Geology (BEG), middle and high school teachers, and UT graduate students (NSF GK-12 fellows) working together through the GK-12 program, is a textbook example of how universities can facilitate this quest, benefiting education at both K-12 and university levels. In 1992, "The Great K-T Extinction Debate" was developed as an activity in the Planet Earth class at the Liberal Arts and Science Academy of Austin as an interdisciplinary approach to science. Taking advantage of the media attention generated by the impact scenario for the K-T extinction, the activity consists of students participating in a simulated senate hearing on the potential causes of the K-T extinction and their implications for society today. This activity not only exposes students to the wide range of science involved in understanding mass extinctions, but also to the social, political and economic implications when this science is brought into the public arena and the corresponding use of data in decision making and disaster preparedness. While "The Great K-T Extinction Debate" was always a popular and effective activity with students, it was in desperate need of updating to keep pace with the evolving scientific debate over the cause of the K-T extinction and the growing body of impact evidence discovered over the past decade. By adding two inquiry-based learning activities that use real geophysical data collected by scientists studying the buried Chicxulub feature as a

  6. Science Communication versus Science Education: The Graduate Student Scientist as a K-12 Classroom Resource

    2005-01-01

    Science literacy is a major goal of science educational reform (NRC, 1996; AAAS, 1998; NCLB Act, 2001). Some believe that teaching science only requires pedagogical content knowledge (PCK). Others believe doing science requires knowledge of the methodologies of scientific inquiry (NRC, 1996). With these two mindsets, the challenge for science educators is to create models that bring the two together. The common ground between those who teach science and those who do science is science communication, an interactive process that galvanizes dialogue among scientists, teachers, and learners in a rich ambience of mutual respect and a common, inclusive language of discourse . The dialogue between science and non-science is reflected in the polarization that separates those who do science and those who teach science, especially as it plays out everyday in the science classroom. You may be thinking, why is this important? It is vital because, although not all science learners become scientists, all K-12 students are expected to acquire science literacy, especially with the implementation of the No Child Left Behind Act of 2001 (NCLB). Students are expected to acquire the ability to follow the discourse of science as well as connect the world of science to the context of their everyday life if they plan on moving to the next grade level, and in some states, to graduate from high school. This paper posits that science communication is highly effective in providing the missing link for K-12 students cognition in science and their attainment of science literacy. This paper will focus on the "Science For Our Schools" (SFOS) model implemented at California State Univetsity, Los Angeles (CSULA) as a project of the National Science Foundation s GK-12 program, (NSF 2001) which has been a huge success in bridging the gap between those who "know" science and those who "teach" science. The SFOS model makes clear the distinctions that identify science, science communication, science

  7. An Increase in Medical Student Knowledge of Radiation Oncology: A Pre-Post Examination Analysis of the Oncology Education Initiative

    International Nuclear Information System (INIS)

    Purpose: The Oncology Education Initiative was created to advance oncology and radiation oncology education by integrating structured didactics into the existing core radiology clerkship. We set out to determine whether the addition of structured didactics could lead to a significant increase in overall medical student knowledge about radiation oncology. Methods and Materials: We conducted a pre- and posttest examining concepts in general radiation oncology, breast cancer, and prostate cancer. The 15-question, multiple-choice exam was administered before and after a 1.5-hour didactic lecture by an attending physician in radiation oncology. Individual question changes, overall student changes, and overall categorical changes were analyzed. All hypothesis tests were two-tailed (significance level 0.05). Results: Of the 153 fourth-year students, 137 (90%) took the pre- and posttest and were present for the didactic lecture. The average test grade improved from 59% to 70% (p = 0.011). Improvement was seen in all questions except clinical vignettes involving correct identification of TNM staging. Statistically significant improvement (p ≤ 0.03) was seen in the questions regarding acute and late side effects of radiation, brachytherapy for prostate cancer, delivery of radiation treatment, and management of early-stage breast cancer. Conclusions: Addition of didactics in radiation oncology significantly improves medical students' knowledge of the topic. Despite perceived difficulty in teaching radiation oncology and the assumption that it is beyond the scope of reasonable knowledge for medical students, we have shown that even with one dedicated lecture, students can learn and absorb general principles regarding radiation oncology

    PolarTREC (Teachers and Researchers Exploring and Collaborating) is a National Science Foundation (NSF) funded program in which K-12 teachers participate in hands-on field research experiences in the polar regions. PolarTREC highlights the importance of involving teachers in scientific research in regards to their careers as educators and their ability to engage students in the direct experience of science. To date, PolarTREC has placed over 90 teachers with research teams in the Arctic and Antarctic. Published results of our program evaluation quantify the effect of the field experience on the teachers' use of the real scientific process in the classroom, the improvement in science content taught in classrooms, and the use of non-fiction texts (real data and science papers) as primary learning tools for students. Teachers and students both report an increase of STEM literacy in the classroom content, confidence in science education, as well as a markedly broadened outlook of science as essential to their future. Research conducted with science teams affirms that they are achieving broader impacts when PolarTREC teachers are involved in their expeditions. Additionally, they reported that these teachers making vital contributions to the success of the scientific project.

    The protein YbiV from Escherichia coli K12 MG1655 is a hypothetical protein with sequence homology to the haloacid dehalogenase (HAD) superfamily of proteins. Although numerous members of this family have been identified, the functions of few are known. Using the crystal structure, sequence analysis, and biochemical assays, we have characterized ybiV as a HAD phosphatase. The crystal structure of YbiV reveals a two domain protein, one with the characteristic HAD hydrolase fold, the other an inserted a/b fold. In an effort to understand the mechanism we also solved and report the structures of YbiV in complex with beryllofluoride (BeF3-) and aluminum trifluoride (AlF3) which have been shown to mimic the phosphorylated intermediate and transition state for hydrolysis, respectively, in analogy to other HAD phosphatases. Analysis of the structures reveals the substrate binding cavity, which is hydrophilic in nature. Both structure and sequence homology indicate ybiV may be a sugar phosphatase, which is supported by biochemical assays which measured the release of free phosphate on a number of sugar-like substrates. We also investigated available genomic and functional data in an effort to determine the physiological substrate.

    Central Washington University has started a five-year NSF-funded GK-12 project to bring the study of our local river - The Yakima - into 5-11th grade science classes. Faculty members from Geological Sciences have teamed with others from Biology, Chemistry, and Resource Management to develop the Yakima WATERS Project (Watershed Activities To Enhance Research in Schools). This interdisciplinary outreach project teams graduate students with local teachers to bring authentic watershed research into the curriculum. The interdisciplinary research themes are: Riparian Ecology and Biodiversity; Water Chemistry and Quality; Geomorphology and Climate Change; and Changes in Land and Water Use. The Yakima Watershed contains several communities that are traditionally underrepresented in science - Native American, Hispanic, and rural populations. One of the key outcomes we will assess is whether a place-based science study such as this is successful in improving minority students' science scores and whether graduate students from underrepresented groups can be attracted and retained in STEM graduate programs. The project is in its early stages, so results of K-12 student science achievement are not yet available. One unexpected, but positive preliminary result is the possibility of further interdisciplinary research that may stem from the close project-driven interactions between people of different STEM subjects. Faculty members, graduate students, and teachers often fail to interact with members of other departments, but through Project activities support networks are forming and ideas for further research are being developed.

    In the classroom, the interaction between students, teachers, and datasets is becoming more game like. Software such as GoogleEarth allow students to interact with data on a more personal level; allowing them the dynamically change variables, move arbitrarily, and personalize their experience with the datasets. As this becomes more immersive, traditional software control such as keyboard and mouse begin to hold the student back in terms of intuitive interfacing with the data. This is a problem that has best been tackled by modern gaming systems such as the Wii, XBox 360, and Playstation 3 Systems. By utilizing the solutions given by these gaming systems, it is possible to further a students immersion with a system. Through an NSF ITEST (Information and Technology Experiences for Students and Teachers) grant, researchers at the University of Maine have experimented with using the game controller that is used for interacting with the Nintendo Wii (often called a Wiimote) with existing geodynamic systems in an effort to eases interaction with these systems. Since these game controllers operate using Bluetooth, a common protocol in computing, Wiimotes can easily communicate with existing laptop computers that are issued to Maine students. This paper describes the technical requirements, setup, and usage of Wiimotes as an input device to complex geodynamical systems for use in the K-12 classroom.

    Full Text Available Advanced Energy Management Control Systems (EMCS offer an excellent means of reducing energy consumption in Heating, Ventilating and Air Conditioning (HVAC systems while maintaining and improving indoor environmental conditions. This can be achieved through the use of computational intelligence and optimization with a building automation system and multiple sensors, which can be quite expensive. However, energy awareness and proper scheduling achieve the best opportunities to save energy with little to no cost for existing facilities. These “low-tech/low-cost” ideas are easily implemented and quickly reduce utility costs. This article includes actual utility data and information gathered over the past 20 years while performing energy audits at several K-12 Schools in North Carolina, discusses well known and documented control strategies that are rarely implemented in most school districts and universities and will extrapolate savings for an entire school district based on real data. These processes can also be integrated into an EMCS to perform several intelligent functions achieving optimal system performance. This article focuses on control strategies utilizing time-of-day scheduling that can be used with 7-day programmable thermostats, electronic time controllers and a Building Automation System (BAS. These controllers (7d-prog. thermostat, electronic time controller and BAS will achieve lower energy consumption while maintaining occupant comfort by performing and prioritizing the appropriate actions. Real savings can be achieved quickly by utilizing these common sense approaches to control existing HVAC and lighting systems in schools.

    Mansy, Donna Lachman

    The purpose of this quantitative study was to investigate Brain Based Learning (BBL) techniques in teaching science. Participants included 216 K-12, full-time, regular education teachers from 8 Northeast Tennessee school systems who taught at least 1 science class. Specifically this research was guided by 7 research questions on teachers' perceptions and practices in teaching science. Data were collected by a survey that consisted of 82 statements where teachers rated their level of agreement and was distributed online via Survey Monkey. The first portion of my survey included demographic identifiers, teachers' knowledge of the term BBL, and inquiries regarding science background and training. The remainder of the statements were focused on teachers' perceptions and practices of BBL strategies in teaching science. The final item was open-ended and allowed teachers to share comments related to teaching science. For statements 6-81, participants responded by using a 5-point Likert scale that ranged from 1 (strongly disagree) to 5 ( strongly agree). Quantitative data were analyzed with a series of independent samples t tests, one-way analysis of variance tests, and a Pearson correlation coefficient. The results of the study indicate that teachers' perceptions are positively correlated to their self-reported practices. Females, in general, and elementary teachers tend to practice BBL strategies in teaching science significantly more than other subgroups.

In the present book the world's leading experts have compiled the current practice-relevant knowledge of neuro-oncologic diseases. The book's clear structure and the uniform presentation of all chapters make this volume a valuable reference, especially for practice-oriented activities, allowing swift access to information about current treatment standards. Hence it will be of great value to both clinicians and researchers. (orig.)

  17. Oncologic emergencies. Analysis of surgical outcomes

    International Nuclear Information System (INIS)

    Selecting the optimal treatment strategy for oncologic emergencies requires appropriate condition assessment. In the present study, we report on an algorithm which we developed for such cases. Preoperative pathological conditions, clinical course and prognosis were analyzed using abdominal X-ray and computed tomography images from 11 patients (male: n=8; age range, 42 to 73 years median age, 57 years; female: n=3; age range, 53 to 90 years; median age, 54 years) with oncologic emergencies who underwent laparotomy at our department between January 2003 and December 2007. The carcinoma type comprised seven cases of colon and rectum cancer, and one each of esophageal, intrahepatic cholangiocellular, hepatocellular and cervical cancers. The eight patients with residual tumors died, while the three without residual tumors (all with colon cancer) remained alive over the 26-month follow-up period. We conclude that patients with colon cancer without residual tumors have a greater rate of recurrence-free survival. (author)

    2007-01-01

    Radiation Oncology: A Physicist's-Eye View was written for both physicists and medical oncologists with the aim of helping them approach the use of radiation in the treatment of cancer with understanding, confidence, and imagination. The book will let practitioners in one field understand the problems of, and find solutions for, practitioners in the other. It will help them to know "why" certain approaches are fruitful while, at the same time, encouraging them to ask the question "Why not?" in the face of assertions that some proposal of theirs is impractical, unreasonable, or impossible. Unlike a textbook, formal and complete developments of the topics are not among the goals. Instead, the reader will develop a foundation for understanding what the author has found to be matters of importance in radiation oncology during over thirty years of experience. Presentations cover, in largely non-technical language, the principal physical and biological aspects of radiation treatment and address practical clinical c...

    Cancer is a major disease that affects a significant proportion of the population worldwide. With a decrease in mortality due to advancements in oncology treatment, there is an expanding role for psychosocial oncology. A satellite clinic for medical treatment (only chemotherapy) of cancer is available at the Guelph General Hospital (GGH). Patients accessing the chemotherapy clinic at GGH have minimal access to psychosocial or supportive care and it is not known if the existing services are addressing the psychosocial symptoms of cancer patients. Participants were asked to complete an anonymous survey which included self-report measures of depression, symptom severity, quality of life, and social support while receiving treatment at this facility. There was a great deal of variability in the patients' emotional symptoms at this satellite clinic, though many patients reported emotional difficulties. Greater social work presence may lead to better identification of patients who would benefit from psychosocial oncology services. PMID:24193219

    2016-01-01

    This paper describes three conceptual areas in physics that are particularly important targets for educational interventions in K-12 science. These conceptual areas are force and motion, conservation of energy, and geometrical optics, which were prominent in the US national and four US state standards that we examined. The four US state standards that were analyzed to explore the extent to which the K-12 science standards differ in different states were selected to include states in different geographic regions and of different sizes. The three conceptual areas that were common to all the four state standards are conceptual building blocks for other science concepts covered in the K-12 curriculum. Since these three areas have been found to be ripe with deep student misconceptions that are resilient to conventional physics instruction, the nature of difficulties in these areas is described in some depth, along with pointers towards approaches that have met with some success in each conceptual area.

  4. Respiration shutoff in Escherichia coli K12 strains is induced by far ultraviolet radiations and by mitomycin C.

    Ultraviolet radiations (254 nm) (UV) cause respiration to shutoff in Escherichia coli B/r. It has been reported [P.A. Swenson, Photochem. Photobiol., 33 (1981) 855-859 and J. Barbé, A. Vericat and R. Guerrero, Mutation Res., 120 (1983) 1-5] that E. coli K12 strains do not shut off respiration after UV. The latter authors also reported that mitomycin C did not cause this 'SOS' response. In this paper we report that higher UV fluences than were previously used will cause respiration shutoff in K12 strain W3110 and that cyclic AMP increases the sensitivity of respiration shutoff of irradiated cell suspensions. We also report that mitomycin C shuts off respiration in this strain. Neither UV nor mitomycin C causes respiration shutoff in the recA56 derivative of W3110. Thus respiration shutoff is a recA dependent response to UV and mitomycin C in E. coli K12 strains.

    In oncology, little is known about dignity, dignity-related distress and the issues that influence the sense of dignity for patients. Dignity is personal, subject to changes depending on the experience and the path of life. In oncology some patients feel that their dignity is directly related to the disease, to physical and emotional symptoms, to the highest level of physical and cognitive autonomy and to the continuity of the self. Patient dignity inventory (PDI) is a validate tool designed to measure various sources of dignity-related distress among patients nearing the end of life and serve as a screening tool to assess a broad range of issues that influence the sense of dignity. Dignity therapy is a novel focused psychotherapy consisting in a brief semi-structured interview, audio-recorded and transcribed in order to obtain the "generativity document". The patients are invited to tell about their life history, and to leave words of guidance and offer instructions to pass along to their son, daughters, husband, wife, parents, others. The generativity document is the result of process of emotional and existential care for the patients and a gift for everybody will receive it. PMID:27093325

    WEST (Water, the Environment, Science and Teaching) is an NSF-funded GK-12 program at the University of Utah. WEST partners graduate students in the sciences with K-12 teachers to enhance inquiry and place- based science teaching in the Salt Lake City urban area. This region is unique in that habitats relating to the entire local hydrologic cycle are accessible within 30 minutes drive of the city. Great Salt Lake, a large closed-basin lake northwest of the city, generates lake-effect snows that fall on the mountains to the east and serves as the terminal point for rivers and streams that drain over 89,000 km2. The lake's salinity ranges from 14-25% and only a few halophilic species are able to survive in its waters. Despite the low diversity, brine shrimp, brine flies, algae and bacteria are abundant in Great Salt Lake and provide the basis of the food chain for millions of migratory shorebirds and waterfowl that feed in the open water, wetlands and saline flats. WEST has teamed up with researchers from the University of Utah, the USGS, the Utah State Dept. of Environmental Quality, local advocacy groups and a private consulting firm to develop a series of projects that involve K-12 students in an actual research project to study the effects of anthropogenic influences on the lake. The study will produce site-specific water-quality standards to protect the invertebrates, shorebirds, and waterfowl that utilize Great Salt Lake. Students will participate in a research cruise on the lake, collecting samples and data to contribute to an online database that will be shared among participating schools. Students will learn about navigation tools, collect and examine brine shrimp, and measure concentrations of optical brighteners and cyanobacteria as indicators of anthropogenic influences to Great Salt Lake. Parts of the southern arm of the lake are stratified into an upper and lower brine layer and the interface between the two layers can be identified by abrupt changes in

    The E885 collaboration utilized the 1.8 GeV/c K^- beam line at the AGS to accumulate 3 x 10^5 (K^-,K^+) events. Xi hypernuclear states are expected to be produced through the reaction K^- + ^{12}C -> K^+ + ^{12}_{Xi}Be. The measured missing-mass spectrum indicates the existence of a signal below the threshold for free Xi production. Although the resolution was not sufficient to resolve discrete hypernuclear states, the excess of events in the region of missing mass, kinematically inaccessible in free Xi production, is compared to theoretical prediction for ^{12}_{Xi}Be production.

    One of the challenges in NASA ROSES E/PO is translating cutting edge research into products for which there is a demonstrated need. Rather than working from the premise that the "research is so cool’ that K-12 students or the public should learn about it, it is key to consult with the target audience to identify what their needs really are. The partnership between NJACE, Innovative Orbital Design, Inc., and Princeton offered a unique opportunity to translate intriguing but theoretical and mathematical research related to low energy orbits into a valuable education product. NJACE worked with educators to identify several needs with an intellectual link to this research: 1) Understanding of Gravity and Newton's Laws, 2) Understanding of Energy and Energy Transformations, 3) Integration of the sciences with math and technology, and 4) Knowledge of NASA's past accomplishments (such as the moon landings). Based on these identified needs, two science units were developed for students in grades 5-12 that integrate astronomy, physics, and the life sciences with math and technology. In addition an engaging public lecture was developed that tells a personal story of the quest for more economic space travel. In the past year, the workshops have been presented on three occasions, reaching over 75 teachers and demand exceeded available space with numerous teachers on waiting lists. The lecture has been presented numerous times at planetariums, museums, amateur astronomy and other clubs. We hope that our partnership will serve as a useful example of how to translate cutting edge research into valuable education products with an identified need. We will provide handouts with links to a website where the products and training can be downloaded in hope that others will help disseminate our product.

    Sulphoquinovose (SQ, 6-deoxy-6-sulphoglucose) has been known for 50 years as the polar headgroup of the plant sulpholipid in the photosynthetic membranes of all higher plants, mosses, ferns, algae and most photosynthetic bacteria. It is also found in some non-photosynthetic bacteria, and SQ is part of the surface layer of some Archaea. The estimated annual production of SQ is 10,000,000,000 tonnes (10 petagrams), thus it comprises a major portion of the organo-sulphur in nature, where SQ is degraded by bacteria. However, despite evidence for at least three different degradative pathways in bacteria, no enzymic reaction or gene in any pathway has been defined, although a sulphoglycolytic pathway has been proposed. Here we show that Escherichia coli K-12, the most widely studied prokaryotic model organism, performs sulphoglycolysis, in addition to standard glycolysis. SQ is catabolised through four newly discovered reactions that we established using purified, heterologously expressed enzymes: SQ isomerase, 6-deoxy-6-sulphofructose (SF) kinase, 6-deoxy-6-sulphofructose-1-phosphate (SFP) aldolase, and 3-sulpholactaldehyde (SLA) reductase. The enzymes are encoded in a ten-gene cluster, which probably also encodes regulation, transport and degradation of the whole sulpholipid; the gene cluster is present in almost all (>91%) available E. coli genomes, and is widespread in Enterobacteriaceae. The pathway yields dihydroxyacetone phosphate (DHAP), which powers energy conservation and growth of E. coli, and the sulphonate product 2,3-dihydroxypropane-1-sulphonate (DHPS), which is excreted. DHPS is mineralized by other bacteria, thus closing the sulphur cycle within a bacterial community.

VISL will allow users to perform guided experiments using the Ice Sheet System Model (ISSM), a state-of-the-art ice flow model developed at NASA's Jet Propulsion Laboratory and UC Irvine that simulates the near-term evolution of the ice sheets on Greenland and Antarctica. VISL users will access ISSM via a graphical interface that can be launched from a web browser on a computer, tablet or smart phone. Users select climate conditions and run time by moving graphic sliders then watch how a given region evolves in time under those conditions. Lesson plans will include conceptual background, instructions for table top experiments related to the concepts addressed in a given lesson, and a guide for performing model experiments and interpreting their results. Activities with different degrees of complexity will aim for consistency with NGSS Physical Science criteria for different grade bands (K-2, 3-5, 6-8, and 9-12), although they will not be labeled as such to encourage a broad user base. Activities will emphasize the development of physical intuition and critical thinking skills, understanding conceptual and computational models, as well as observation recording, concept articulation, hypothesis formulation and testing, and mathematical analysis. At our present phase of development, we seek input from the greater science education and outreach communities regarding VISL's planned content, as well as additional features and topic areas that educators and students would find useful.

    The Center for Microbial Oceanography: Research and Education (C-MORE) is a NSF Science and Technology Center based at the University of Hawaii. The C-MORE education and outreach program offers a variety of resources and professional development opportunities for science educators, including online resources, participation in oceanography research cruises, teacher-training workshops, mini-grants to incorporate microbial oceanography-related content and activities into their classroom and, most recently, C- MORE science kits. C-MORE science kits provide hands-on classroom, field, and laboratory activities related to microbial oceanography for K-12 students. Each kit comes with complete materials and instructions, and is available free of charge to Hawaii's public school teachers. Several kits are available nationwide. C-MORE science kits cover a range of topics and technologies and are targeted at various grade levels. Here is a sampling of some available kits: 1) Marine Murder Mystery: The Case of the Missing Zooxanthellae. Students learn about the effect of climate change and other environmental threats on coral reef destruction through a murder-mystery experience. Participants also learn how to use DNA to identify a suspect. Grades levels: 3-8. 2) Statistical sampling. Students learn basic statistics through an exercise in random sampling, with applications to microbial oceanography. The laptops provided with this kit enable students to enter, analyze, and graph their data using EXCEL. Grades levels: 6-12. 3) Chlorophyll Lab. A research-quality fluorometer is used to measure the chlorophyll content in marine and freshwater systems. This enables students to compare biomass concentrations in samples collected from various locations. Grades levels: 9-12. 4) Conductivity-Temperature-Depth (CTD). Students predict how certain variables (e.g., temperature, pressure, chlorophyll, oxygen) vary with depth. A CTD, attached to a laptop computer, is deployed into deep water

    As science educators based in institutional outreach programs, we work with many scientists on education and outreach projects involving teachers, students, and the public. While our scientist colleagues bring varied disciplinary interests, educational expertise, and communication skills to their education work, one strength that all scientists bring to these collaborations is their profound knowledge of the inquiry process. We have begun to develop a program of professional development for scientists that focuses on scientific inquiry in the classroom. Inquiry is the appropriate topic of focus for an initial professional development experience for scientists, because it is a crucial and broadly applicable part of national science education goals, and because all scientists understand it in a deep and personal way. As articulated in the National Science Education Standards, inquiry is both a recommended strategy for learning and teaching scientific concepts, and a content area in its own right, with the aim that students understand the process of science and can conduct scientific investigations. We will describe our multi-faceted program, which includes professional development workshops, development and sharing of resources, and a research-with-evaluation study to examine the readiness, response, and needs of the scientific community for professional development to further its education work. We will discuss ways in which scientists can apply their understanding of inquiry to their education work as well as identify other needs that must also be addressed. While inquiry is not the only thing that "busy scientists need to know," it is a good topic for starting fruitful conversations among scientists, K-12 educators, and those who bridge these communities.

    The recurring challenge for curriculum developers is how to efficiently prepare K-12 classroom teachers to use new curricula. First-year teachers, numbering nearly 250,000 in the US each year, have the greatest potential to impact the largest number of students because they have potential to be in the classroom for thirty years. At the same time, these novice teachers are often the most open minded about adopting curricular innovation because they are not yet deeply entrenched in existing practices. To take advantage of this high leverage point, a collaborative of space scientists and science educators at the University of California, Berkeley’s Lawrence Hall of Science and Center for Science Education at the Space Sciences Laboratory with experts from the Astronomical Society of the Pacific, the University of Wyoming, and the CAPER Center for Astronomy & Physics Education experimented with a unique professional development model focused on helping master teachers work closely with pre-service teachers during their student teaching internship field experience. The Advancing Mentor and Novice Teachers in Space Science (AMANTISS) team first identified master teachers who supervise novice, student teachers and trained these master teachers to use the GEMS Space Science Curriculum Sequence. Then, these master teachers were mentored in coaching interning student teachers assigned to them in using GEMS materials. Evaluation showed that novice teachers mentored by the master teachers felt knowledgeable after teaching the GEMS units. However, they seemed relatively less confident about the solar system and objects beyond the solar system. Overall, mentees felt strongly at the end of the year that they have acquired good strategies for teaching the various topics, suggesting that the support they received while teaching and working with a mentor was of real benefit to them.

    Businesses lack enough qualified applicants to fill the increasing need for scientists and engineers while educators lack many resources for science programs in K-12 schools. This series of case studies searched for successful collaborations between the two in four geographic locations: Boise, Idaho; Dallas, Texas; Los Angeles County, California, and Orange County, California. These science education partnerships were investigated to gain an understanding of long-term partnership structure, functioning and evaluation methods. Forty-nine individual interviews with representatives from the groups of stakeholders these programs impact were also conducted. Stakeholder groups included students, teachers, parents, school administrators, business liaisons, and non-profit representatives. Several recurring themes in these partnerships reinforced the existing literature research findings. Collaboration and communication between partners, teacher professional development, the need for more minority and female representation in physical science careers, and self-efficacy in relation to how people come to view their scientific abilities, are among these themes. Topics such as program replication, the importance of role models, programs using "hands-on" activities, reward systems for program participants, and program outcome measurement also emerged from the cases investigated. Third-party assistance by a non-profit entity is occurring within all of these partnerships. This assistance ranges from a service providing material resources such as equipment, lesson plans and meeting space, to managing the partnership fundraising, program development and evaluations. Discussions based upon the findings that support or threaten sustainment of these four partnerships, what a "perfect" partnership might look like, and areas in need of further investigation conclude this study.

    precoce são fundamentais para a melhora da sobrevida.OBJECTIVES: To provide a foundation for the diagnostic, prophylactic and therapeutic management of febrile neutropenia and sepsis in children with oncological diseases, with special attention to new protocols and guidelines. SOURCES: A review of the scientific literature utilizing an electronic bibliographic search on MEDLINE, Medscape, SciELO, Google, Cochrane and PubMED using the keywords febrile, neutropenic, cancer, children, sepsis, intensive, care. Articles published between 1987 and 2007 were selected, with preference given to review articles, protocols, systematic reviews, epidemiological studies, task force recommendations and phase III clinical trials. Consensus documents published by the Infectious Diseases Society of America, the Center for Diseases Control and the Infectious Diseases Working Party of the German Society of Hematology and Oncology, in addition to the recommendations of the World Federation of Pediatric Intensive and Critical Care Societies and Society of Critical Care Medicine, were also reviewed. SUMMARY OF THE FINDINGS: The use of aggressive chemotherapy regimens, bone marrow transplantation and intensive care resources have increased the survival rates of children with cancer and also their infectious morbidity, with septic complications as the principal cause of mortality. Several risk factors have been identified, such as neutropenia, oncology type, clinical signs and inflammatory response markers (polymerase chain reaction, procalcitonin and also increased resistance to antimicrobials and antifungal agents. Protocols for risk classification, diagnosis and treatment should be established at each service, taking into account the microbiological flora of each population. Pediatric intensive care has increased the short and long-term survival of these patients. CONCLUSIONS: Oncology patients are particularly vulnerable to infectious complications. Early identification and treatment are

    Cancer treatment is a major burden for the patient and its family that requires an individualized management by healthcare professionals. Nurses are in charge of coordinating care and are the closest healthcare professionals to patient and family; however, in Spain, there are not standard protocols yet for the management of oncology patients. The Spanish Oncology Nursing Society developed between 2012 and 2014 the SHARE project, with the aim of establishing strategies to improve quality of life and nursing care in oncology patients. It was developed in 3 phases. First, a literature search and review was performed to identify nursing strategies, interventions and tools to improve cancer patients' care. At the second stage, these interventions were agreed within a group of oncology nursing experts; and at the third phase, a different group of experts in oncology care categorized the interventions to identify the ones with highest priority and most feasible to be implemented. As a result, 3 strategic actions were identified to improve nursing care during cancer treatment: To provide a named nurse to carry out the follow up process by attending to the clinic or telephonic consultation, develop therapeutic education with adapted protocols for each tumor type and treatment and ensure specific training for nurses on the management of the cancer patients. Strategic actions proposed in this paper aim to improve cancer patients' healthcare and quality of life through the development of advanced nursing roles based on a higher level of autonomy, situating nurses as care coordinators to assure an holistic care in oncology patients.

  19. Osteonecrosis - complication at oncological treatment in childhood

    International Nuclear Information System (INIS)

    Osteonecrosis is one of serious complications at oncological treatment of children. The etiopathogenesis has not been completely elucidated, mostly it has a multifactorial character. The incidence is in 1,5 - 9,3 % range. ON affects predominantly the weight bearing joints. It affects mostly the patients with acute lymphoblastic leukemia and those at adolescent age. The course of disease is unpredictable. The changes at early stages can be reversible, but at some patients the disease progresses and can lead to a disability. At Children oncology clinic of Children teaching hospital in Bratislava during the years 1992 - 2008 we identified 12 patients affected by ON out of 146 children with ALL (8,2 %), 1 out of 42 with NHL (2,4 %) and 1 out of 42 with HL (2,4 %). The age at diagnosis of malignity: 4y7m - 17y, the age at diagnosis ON: 10y5m - 19y. Further course: regression - 2 patients, stabilised state - 6 patients, progression - 3 patients. 3 patients were lost from our follow up. The treatment was conservative, with the exception of one patient, who had to undergo surgery due to the progression of disease. To avoid the risk of inducing ON during the treatment of oncological patient in childhood it is important to optimalize the therapeutical protocols and to diagnose this complication early. (author)
