Objectives To calculate design-corrected estimates of the effect of screening on prostate cancer mortality by centre in the European Randomised Study of Screening for Prostate Cancer (ERSPC). Setting The ERSPC has shown a 21% reduction in prostate cancer mortality in men invited to screening with follow-up truncated at 13 years. Centres either used pre-consent randomisation (effectiveness design) or post-consent randomisation (efficacy design). Methods In six centres (three effectiveness design, three efficacy design) with follow-up until the end of 2010, or maximum 13 years, the effect of screening was estimated as both effectiveness (mortality reduction in the target population) and efficacy (reduction in those actually screened). Results The overall crude prostate cancer mortality risk ratio in the intervention arm vs control arm for the six centres was 0.79 ranging from a 14% increase to a 38% reduction. The risk ratio was 0.85 in centres with effectiveness design and 0.73 in those with efficacy design. After correcting for design, overall efficacy was 27%, 24% in pre-consent and 29% in post-consent centres, ranging between a 12% increase and a 52% reduction. Conclusion The estimated overall effect of screening in attenders (efficacy) was a 27% reduction in prostate cancer mortality at 13 years' follow-up. The variation in efficacy between centres was greater than the range in risk ratio without correction for design. The centre-specific variation in the mortality reduction could not be accounted for by the randomisation method.

Cancer centre Web sites can be a useful tool for distributing information about the benefits of physical activity for breast cancer (bca) survivors, and they hold potential for supporting health behaviour change. However, the extent to which cancer centre Web sites use evidence-based behaviour change techniques to foster physical activity behaviour among bca survivors is currently unknown. The aim of our study was to evaluate the presentation of behaviour-change techniques on Canadian cancer centre Web sites to promote physical activity behaviour for bca survivors. All Canadian cancer centre Web sites ( n = 39) were evaluated by two raters using the Coventry, Aberdeen, and London-Refined (calo-re) taxonomy of behaviour change techniques and the eEurope 2002 Quality Criteria for Health Related Websites. Descriptive statistics were calculated. The most common behaviour change techniques used on Web sites were providing information about consequences in general (80%), suggesting goal-setting behaviour (56%), and planning social support or social change (46%). Overall, Canadian cancer centre Web sites presented an average of M = 6.31 behaviour change techniques (of 40 that were coded) to help bca survivors increase their physical activity behaviour. Evidence of quality factors ranged from 90% (sites that provided evidence of readability) to 0% (sites that provided an editorial policy). Our results provide preliminary evidence that, of 40 behaviour-change techniques that were coded, fewer than 20% were used to promote physical activity behaviour to bca survivors on cancer centre Web sites, and that the most effective techniques were inconsistently used. On cancer centre Web sites, health promotion specialists could focus on emphasizing knowledge mobilization efforts using available research into behaviour-change techniques to help bca survivors increase their physical activity.

Objective: To determine a frequency distribution of the type and clinical profile of cancer cases registered at the Shaukat Khanum Memorial Cancer Hospital and Research Centre (SKMCH and RC). Study Design: A retrospective, observational study. Place and Duration of Study: The SKMCH and RC, Lahore, from December 1994 to December 2012. Methodology: The time period taken into consideration for the three most common diagnoses was December 1994 - December 2012. Summaries were obtained for gender, age-group, and cancer type on: (i) all age-groups, both genders combined; (ii) adults (> 18 years); (iii) adult males (> 18 years); (iv) adult females (> 18 years); and (v) children (18 years). For a subset of cases registered between January 2004 to December 31, 2012 (9 years), summaries on cancers, age, addiction, family history, disease stage, and grade were obtained for the above groups. Statistical Package for Social Sciences, version 19, was used to analyze the data. Results: The most common malignancies, for the 18-year time period, among adults, were those of breast (11,848/ 49,765, 23.81%), lip and oral cavity (3, 291/49, 765, 6.61%), and liver and intrahepatic bile ducts (2, 836/49, 765, 5.70%). Conclusion: Hospital-based results obtained from various oncology hospital and departments, can be considered as an effective way forward in getting a preview of cancer burden in the region.

The increase of breast cancer in young women under 40 years and the increasing age of women at the time of the birth of their first child underlines the importance to implement counselling for fertility-preserving strategies in the management of breast cancer care. We present the fertility-preserving procedures performed after routine counselling for primary breast cancer patients in a large certified breast cancer centre. Since November 2006, patients aged below 40 years with histologically confirmed breast cancer are routinely counselled on fertility-preserving possibilities before breast surgery and chemotherapy in the fertility centre of the University Women's Hospital in Tuebingen. The recommendations are based on the treatment recommendations of the network FertiPROTEKT. During the last 40 months, 56 primary breast cancer patients were counselled. Forty-one of these patients were hormone receptor positive. Thirty-four patients (63%) underwent fertility-preserving strategies. The majority of the patients (n = 22) decided on ovarian tissue cryopreservation. GnRH protection was performed in 14 patients. In 12 patients an ovarian stimulation protocol was initiated to cryopreserve fertilized or unfertilized oocytes. A combination of different fertility-preserving methods was performed in 12 patients. The preservation of ovarian function and fertility are of great importance to young breast cancer patients. Counselling on fertility-preserving strategies is therefore critical in these patients and should be routinely performed.

Childhood cancers are relatively uncommon in comparison to adult cancers. There is no literature available to shed light on clinic-pathological types and patterns of care for childhood cancers in our population in North-East India. In this analysis we therefore tried to determine the common childhood cancers diagnosed in our institute, clinical profile of the patients, types of treatment and compliance, and median survival estimates. Leukemia was most common, followed by retinoblastoma, central nervous system tumours and lymphomas. Ascertaining the clinic-pathological profile of childhood cancers in our population is essential for allocation and management of resources for this small but important group of patients.

The paper discusses the development of nuclear physics in developing countries, pointing out the difficulties of research in the future. A proposal for the formation of regional centres is put forward. Arguments justifying the formation of these regional centres are presented together with the suggestion that UNESCO and IAEA act as sponsors and financial supporters of the regional centres. The institutes in the developing countries could serve as a basis for such centres. Countries which are qualified and interested in having and using the facilities of the regional centres should also participate in the financing of them. (author)

Regional Climate Centres (RCCs) are institutions with the capacity and mandate by WMO to develop high quality regional-scale products using global products and incorporating regional information. Recently a pilot network of three RCC consortia was established for the WMO region RA VI (Europe and Middle East): • RCC node on climate data, • RCC node on climate monitoring, • RCC node on long-range forecasting. DWD/Germany has taken the responsibility of the RCC node on climate monitoring (RRC-CM). Further consortium members are Armstatehydromet/Armenia, Météo-France/France, KNMI/The Netherlands, RHMS/Serbia, and TSMS/Turkey. RCCs provide online access to their products and services to national meteorological and hydrological services and to other regional users. Vice versa, RCCs receive data, products, know-how and feedbacks from the meteorological services as a main source for regional information. By the same time, they provide regional data, products and feedbacks to Global Production Centres and Lead Centres for respective verification and product optimisation of the global-scale information. The RCC-CM will perform basic functions covering the domain of climate monitoring: • Annual and monthly climate diagnostic bulletins, • Monthly monitoring maps: global, RAVI, Eastern Mediterranean, South Caucasus, • Reference climatologies and trend maps, • RA VI climate monitoring WebPortal, • Climate watches, • Training; Research and Development (R&D). The poster shows the current stage of development of the RCC-CM by means of example products.

Aims: SPECT technology was introduced in Brazil at the early 80s and, presently, there are more than 230 systems installed in the whole country. In order to establish a quality standard for these systems, a RCP was submitted and received partial support from IAEA for the implementation of regional centres, so that clinics in different regions could be evaluated using the same protocols. Materials and Methods: Six centres were created in 5 public (federal and state) universities and one private philanthropic medical school in: USP-Sao Paulo, UNICAMP-Campinas, CNEN-Rio de Janeiro, UFBA-Salvador, UFPE-Recife and FM/Santa Casa-Porto Alegre. All sites have teaching and technical supports available and there is at least one nuclear medicine physicist in charge. The basic QC/QA set included: 57 Co sheet source, orthogonal hole phantom, quadrant bar phantom, calibrated sources for dose calibrator ( 57 Co, 133 Ba, and 137 Cs) and a DeLuxe SPECT phantom from Data Spectrum Corp. Basic and complete/acceptance protocols were defined as the reference procedures. Measurements and evaluations were performed in 21 (<10%) centres and inter-comparisons were made amongst the groups. Results: Some information about the centres and evaluated systems are presented. A large number of the visited clinics never had any QC tests done except for the manufacturer's installation tests and the daily uniformity test. On the average, most of the cameras needed tuning and one of them had to have the PM tubes re-coupled. The main difficulties encountered by all groups were the lack of physicists in almost all the visited clinics and the inadequate training of many local technologists, especially in the remote areas. In spite of the misunderstanding and scepticism from some of the visited MDs, the majority recognized the importance of proper QC/QA testing. Conclusions: It was shown that regional centres are essential if one aims quality and reliability in the nuclear medicine clinics, especially in a

A full scale model for the centre region of the compact 30 MeV, 350 μA H - cyclotron (TR30) has been constructed, to test the design of critical components and to study beam properties and space charge effects out to the 5. turn (1 MeV). The ion source and injection line system duplicates that used in the TR30. The centre region can be accessed with diagnostic probes at four different angles. The normalized circulating emittances as estimated from beam profile measurements are 1.7π mm-mrad (radially) and 1.8π mm-mrad (vertically). The radial centering error of the beam is less than 1.5 mm. After initial tests the maximum intensity achieved at the 5. turn is 650 μA. This corresponds with a transmission efficiency of 12.5% for a continuous (non-bunched) input beam. No significant space charge effects are observed up to 650 μA. For the TR30 bunching is not a must because of the high current available from the source. Nevertheless, it was considered useful to study beam bunching for the Centre Region Cyclotron (CRC). Some of these results are described. (Author) 11 refs., 6 figs

This series of slides presents the initiative launched in May 2010 by the European Union to develop at national and regional levels the necessary institutional capacity to fight against the CBRN (Chemical, Biological, Radiological and Nuclear) risk. The origin of the risk can be: -) criminal (proliferation, theft, sabotage and illicit traffics), -) accidental (industrial catastrophes, transport accidents...) and -) natural (mainly pandemics). The initiative consists in the creation of Centres of Excellence for providing assistance and cooperation in the field of CBRN risk and the creation of experts networks for sharing best practices, reviewing laws and regulation, developing technical capacities in order to mitigate the CBRN risk. The initiative is complementary to the instrument for nuclear safety cooperation. Regional Centres of Excellence are being set up in 6 regions: South East Europe, South East Asia, North Africa, West Africa, Middle East, and Central Asia covering nearly 40 countries. A global budget of 100 million Euros will be dedicated to this initiative for the 2009-2013 period. (A.C.)

The region consisting of Afghanistan, Pakistan, India, Ceylon, Bangladesh, Burma, Malaysia, Thailand, Singapore and Indonesia is considered for a model study on the possibility of establishing regional fuel cycle centres. Nuclear power generation capacity for this region is estimated and projected through 2000 A.D. and accordingly the demands for various nuclear fuel cycle services are determined. Preliminary calculations show that for the region conversion and fuel fabrication plants may be economically feasible before 1990 whereas reprocessing plants may become feasible only after 1990. The possibility of enrichment plant is even more uncertain. Ore, enrichment and fabrication in future may constitute more than 95-98% of the total fuel cycle cost. For fuel cycle economy, therefore, regional cooperation should be emphasized for these services. Reprocessing has to be considered because of the valuable fissile materials present in the spent fuel. Assuming that regional fuel cycle centre/centres may be established in Bangladesh, the study considered the local advantages and disadvantages of such an effort. Though no major problem could be identified in the case of conversion and fabrication plants, considerable difficulty is anticipated from a large reprocessing plant because of waste management and disposal problems. Bangladesh does not appear to have any suitable waste disposal site in view of the present technology. However, if the long term leaching problemns of solidified wastes are resolved then wastes may be dumped in the sea-canyon in the Bay of Bengal (called the ''Swatch of no ground'') or in the deep underground caverns

Objectives Regional centres and their rural hinterlands support significant populations of non-metropolitan Australians. Despite their importance in the settlement hierarchy and the key medical services provided from these centres, little research has focused on their issues of workforce supply and long-term service requirements. In addition, they are a critical component of the recent growth of 'regional' hub-and-spoke specialist models of service delivery. Methods The present study interviewed 62 resident specialists in four regional centres, seeking to explore recruitment and retention factors important to their location decision making. The findings were used to develop a framework of possible evidence-informed policies. Results This article identifies key professional, social and locational factors, several of which are modifiable and amenable to policy redesign, including work variety, workplace culture, sense of community and spousal employment; these factors that can be targeted through initiatives in selection, training and incentives. Conclusions Commonwealth, state and local governments in collaboration with communities and specialist colleges can work synergistically, with a multiplicity of interdigitating strategies, to ensure a positive approach to the maintenance of a critical mass of long-term rural specialists. What is known about the topic? Rural origin increases likelihood of long-term retention to rural locations, with rural clinical school training associated with increased rural intent. Recruitment and retention policy has been directed at general practitioners in rural communities, with little focus on regional centres or medical specialists. What does this study add? Rural origin is associated with regional centre recruitment. Professional, social and locational factors are all moderately important in both recruitment and retention. Specialist medical training for regional centres ideally requires both generalist and subspecialist skills

Full Text Available This paper explores the findings regarding the impact of recession that began in 2008 in Slovenia to the chosen parameters of quality of regional centres, which are reflected in their attractiveness. We wanted to test the assumption of the impact of recession to the attractiveness of regional centres to both internal migration and commuting flows. To this end, an adjusted gravity spatial interaction model was developed by evaluating regression coefficients. We analysedthe impacts of population size, distance, employment, gross personal income, municipality revenue per capita, average price per square metre of apartments and houses, and age structure in the municipality pertaining to the decision to potentially migrate or commute related to the migration and choice of workplace in the regional centre. The impact of the recession was analysed by comparing the estimations of regression coefficients before the recession (2007 and duringthe recession (2011. It is shown that during the recession, internal migrations to regional centres increased considerably, while commuting to regional centres did not change significantly. We alsoshowed that during the recession, the impact of the distance to the decision to migrate to regional centres slightly increased, while the impact of the distance to the decision to commute did not changesignificantly. Notably, during the crisis the impact of municipality revenue per capita in the regional centre to the analysed flows changed the most: during the recession, the decision to migrate and/orcommute to 'more prosperous' regional centres is made more easily.In the future, it is to be expected that local self-governments will make more effort to consider how to attract taxpayers to their local community and hence enrich the community, while the analysis of theseparameters will become more significant for the individual levels of the local self-government. Gravity models, such as the one used here, include different

Full Text Available Laparoscopic colon resection has established its role as a minimally invasive approach to colorectal diseases. Better long-term survival rate is suggested to be achievable with this approach in colon cancer patients, whereas some doubts were raised about its safety in rectal cancer. Here we report on our single centre experience of rectal laparoscopic resections for cancer focusing on short- and long-term oncological outcomes. In the last 13 years, 248 patients underwent minimally invasive approach for rectal cancer at our centre. We focused on 99 stage I, II, and III patients with a minimum follow-up period of 5 years. Of them 43 had a middle and 56 lower rectal tumor. Laparoscopic anterior rectal resection was performed in 71 patients whereas laparoscopic abdomino-perineal resection in 28. The overall mortality rate was 1%; the overall morbidity rate was 29%. The 5-year disease-free survival rate was 69.7%, The 5-year overall survival rate was 78.8%.

Full Text Available Objective: The Self-administered Leeds Assessment of Neuropathic Symptoms and Signs (S-LANSS is a 7-item self-report scale developed to identify pain which is of predominantly neuropathic origin. The aim of this study was to develop a Malayalam version of the LANSS and to test its validity and reliability in chronic pain patients. Methodology: We enrolled 101 Malayalam-speaking chronic pain patients who visited the Division of Palliative Medicine, Regional Cancer Centre, Thiruvananthapuram, Kerala, India. The translated version of S- LANSS was constructed by standard means. Fifty-one neuropathic pain and fifty nociceptive pain patients were identified by an independent pain physician and were subjected to the new pain scale by a palliative care nurse who was blinded to the diagnosis. The “gold standard diagnosis” is what the physician makes after clinical examination. Its validation, sensitivity, specificity, and positive and negative predictive values were determined. Results: Fifty-one neuropathic pain and fifty nociceptive pain patients were subjected to the Malayalam version of S-LANSS pain scale for validity testing. The agreement by Cohen's Kappa 0.743, Chi-square test P < 0.001, sensitivity 89.58, specificity 84.91, positive predictive value 84.31, negative predictive value 90.00, accuracy by 87.13, and likelihood ratio 5.94. Conclusion: The Malayalam version of S-LANSS pain scale is a validated screening tool for identifying neuropathic pain in chronic pain patients in Malayalam-speaking regions.

Management of Cervical Cancer: Strategies for Limited-Resource Centres - A Guide for Radiation Oncologists

International Nuclear Information System (INIS)

2013-01-01

Cervical cancer remains a significant cause of morbidity and mortality among women globally, even though it is the cancer with the greatest demonstrated potential for secondary prevention. In some regions of the world the incidence is alarmingly high, such as in sub-Saharan Africa, some countries in Latin America, India and South-East Asia. This disease is highly preventable and curable at a relatively low risk and low cost when screening of asymptomatic women is available, together with appropriate diagnosis, treatment and follow-up. In developing clinical guidelines, the International Atomic Energy Agency (IAEA) has selected forms of cancer or clinical situations that are very common in low and middle income Member States and for which radiation oncologists consistently express a need for guidance. Clinical guidelines for the management of cervical cancer do exist in the published literature. However, these guidelines have usually been developed in and for affluent environments where all modern diagnosis and treatment modalities are available for the practitioner. In limited resource environments, the radiation oncologist is faced with the question, what would be the minimally acceptable line of action with the limited resources available? Clinical guidelines focusing on low and middle income countries provide a practical tool to these practitioners. This publication is aimed at the radiation oncologist working in centres with limited resources and treating a large number of patients with cervical cancer on a daily basis. The approach and techniques are intended to be simple, feasible and resource sparing to the extent that this is possible when dealing with a complex treatment modality. The Division of Human Health is placing special emphasis on the subject of cervical cancer, which is addressed not only in this guide but also in regional training courses and coordinated research projects on the subject

Breast cancer remains a worldwide public health problem. In Tunisia, it is considered to be the primary women's cancer and causes high morbidity and mortality. This study aimed to investigate female knowledge, attitudes and practice of breast cancer screening in the region of Monastir (Tunisia). We conducted a descriptive cross-sectional design exploring knowledge, attitudes and practices of women in the region of Monastir on breast cancer screening. The study was conducted in health centres of this region from 1 March 2009 to 30 June 2009. Data were collected via a structured questionnaire containing 15 items on demographic status, knowledge of risk factors and screening methods and attitudes towards the relevance and effectiveness of breast cancer screening. A scoring scheme was used to score women's responses. A total of 900 women agreed to take part in the study. Their mean age was 41.6±12.4 years and 64% did not exceed the primary level of education. According to the constructed scores, 92% of participants had poor knowledge of the specific risk factors for breast cancer and 63.2% had poor knowledge of the screening methods. Proper practice of breast cancer screening was observed in 14.3% of cases. Multiple logistic regression analysis showed that good knowledge of risk factors and screening methods, higher level of education and positive family history of breast cancer were independently correlated with breast cancer screening practice. This study revealed poor knowledge of breast cancer and the screening methods as well as low levels of practice of breast cancer screening among women in the region of Monastir. Results justify educational programs to raise women's adherence to breast cancer screening programs in Tunisia.

The vision of the Calman-Hine paper is of patient-centred care, delivered by co-ordinated services which have genuine partnerships with each other. There is integration of other providers of support, to meet psychological and non-clinical needs. There is access to palliative care when required, from diagnosis onwards, and not just in the terminal stage. Effective communications and networks are the keys to making this vision a reality. Our recommendations are based upon in-depth discussions with purchasers, doctors and nurses, and others involved with cancer services within hospitals or the community across the region. They reflect the priorities placed on the development of good practice. Purchasers and providers should work together to implement these guidelines.

The etiology of gastric cancer is multifactorial. Marked differences in the incidence of gastric cancer among different ethnic groups living in the same geographical area have been observed. This study looked at ethnic and dietary factors in patients with gastric cancer diagnosed at a tertiary referral centre in Sikkim over a period of one year. Patients of 60 years and above were included in the study and divided into four ethnic groups : Bhutias, Lepchas, Rais and other groups. 211 cases underwent upper GI endoscopy and 32 were diagnosed to have gastric cancer. Gastric cancer incidence was highest in Bhutia ethnic group. A trend towards higher intake of smoked meats, fermented vegetables, salt tea, and H.pylori positivity in the Bhutia ethnic group was associated with higher incidence of gastric cancer as compared to other ethnic groups. The study with a referral centre bias showed that Bhutia ethnic group had a higher incidence of gastric cancer as compared to other ethnic groups.

The hydrometeorological alert office (called "Decentrate Functional Centre" - CFD) of Umbria Region, in central Italy, is the office that provides technical tools able to support decisions when significant flood/landslide events occur, furnishing 24h support for the whole duration of the emergency period, according to the national directive DPCM 27 February 2004 concerning the "Operating concepts for functional management of national and regional alert system during flooding and landslide events for civil protection activities purposes" that designs, within the Italian Civil Defence Emergency Management System, a network of 21 regional Functional Centres coordinated by a central office at the National Civil Protection Department in Rome. Due to its "linking" role between Civil Protection "real time" activities and environmental/planning "deferred time" ones, the Centre is in charge to acquire and collect both real time and quasi-static data: quantitative data from monitoring networks (hydrometeorological stations, meteo radar, ...), meteorological forecasting models output, Earth Observation data, hydraulic and hydrological simulation models, cartographic and thematic GIS data (vectorial and raster type), planning studies related to flooding areas mapping, dam managing plans during flood events, non instrumental information from direct control of "territorial presidium". A detailed procedure for the management of critical events was planned, also in order to define the different role of various authorities and institutions involved. Tiber River catchment, of which Umbria region represents the main upper-medium portion, includes also regional trans-boundary issues very important to cope with, especially for what concerns large dam behavior and management during heavy rainfall. The alert system is referred to 6 different warning areas in which the territory has been divided into and based on a threshold system of three different increasing critical levels according

Results This article identifies key professional, social and locational factors, several of which are modifiable and amenable to policy redesign, including work variety, workplace culture, sense of community and spousal employment; these factors that can be targeted through initiatives in selection, training and incentives. Conclusions Commonwealth, state and local governments in collaboration with communities and specialist colleges can work synergistically, with a multiplicity of interdigitating strategies, to ensure a positive approach to the maintenance of a critical mass of long-term rural specialists. What is known about the topic? Rural origin increases likelihood of long-term retention to rural locations, with rural clinical school training associated with increased rural intent. Recruitment and retention policy has been directed at general practitioners in rural communities, with little focus on regional centres or medical specialists. What does this study add? Rural origin is associated with regional centre recruitment. Professional, social and locational factors are all moderately important in both recruitment and retention. Specialist medical training for regional centres ideally requires both generalist and subspecialist skills

The Region of Tuscany Health Department was included as an associated member in WP7 "Healthcare" of the European Partnership for Action Against Cancer (EPAAC), initiated by the EU Commission in 2009. The principal aim was to map centres across Europe prioritizing those that provide public health services and operating within the national health system in integrative oncology (IO). A cross-sectional descriptive survey design was used to collect data. A questionnaire was elaborated concerning integrative oncology therapies to be administered to all the national health system oncology centres or hospitals in each European country. These institutes were identified by convenience sampling, searching on oncology websites and forums. The official websites of these structures were analysed to obtain more information about their activities and contacts. Information was received from 123 (52.1 %) out of the 236 centres contacted until 31 December 2013. Forty-seven out of 99 responding centres meeting inclusion criteria (47.5 %) provided integrative oncology treatments, 24 from Italy and 23 from other European countries. The number of patients seen per year was on average 301.2 ± 337. Among the centres providing these kinds of therapies, 33 (70.2 %) use fixed protocols and 35 (74.5 %) use systems for the evaluation of results. Thirty-two centres (68.1 %) had research in progress or carried out until the deadline of the survey. The complementary and alternative medicines (CAMs) more frequently provided to cancer patients were acupuncture 26 (55.3 %), homeopathy 19 (40.4 %), herbal medicine 18 (38.3 %) and traditional Chinese medicine 17 (36.2 %); anthroposophic medicine 10 (21.3 %); homotoxicology 6 (12.8 %); and other therapies 30 (63.8 %). Treatments are mainly directed to reduce adverse reactions to chemo-radiotherapy (23.9 %), in particular nausea and vomiting (13.4 %) and leucopenia (5 %). The CAMs were also used to reduce pain and fatigue (10.9�

AIM: To identify the methods and protocols of staging CT scans performed for upper GI malignancy throughout the region covered by the South West Cancer Intelligence Service. MATERIALS AND METHODS: A questionnaire relating to the protocols used in the CT staging of upper GI cancer was circulated to all the Cancer Leads and Clinical Directors of Radiology throughout the network covered by the South West Cancer Intelligence Service (SWCIS). Information about the type of scanner, the provision of protocols and the staging of oesophageal, gastric and pancreatic carcinoma was obtained. RESULTS: Twenty one of the twenty six departments contacted responded (81%). Ninety percent of departments perform staging CT scans to a departmental protocol but these protocols vary throughout the region. Most centres have multislice CT technology and all use intravenous contrast media administered via a pump. All centres us a portal venous phase to exclude liver metastasis in all cancers. Thirty-eight to forty percent of centres use an arterial phase of enhancement when examining the oesophagus and stomach. Sixty one percent of centres use an arterial phase and seventy percent of centres use a pancreatic phase of enhancement in addition to a portal venous phase when staging pancreatic carcinoma. Addition imaging of the chest to identify disseminated disease is often performed, 100% of centres include the chest when staging oesophageal malignancy, 87% include the chest in gastric staging and 51% include this additional scan when staging pancreatic carcinoma. The staging scans were reported in 80% of centres by radiologists with a sub-speciality interest in GI malignancy. CONCLUSION: Whilst nearly all centres perform staging CT scans for upper GI malignancy to a departmental protocol there is much variability in the protocols used throughout the South West region

STRENGTHEN AND UPGRADE REGIONAL CAPABILITIES (REGIONAL UNIVERSITY KNOWLEDGE CENTRE PROGRAMME IN HUNGARY

Full Text Available The emerging vision of the modern, innovative Hungarian economy, which can compete successfully in the global arena, made it absolutely necessary to encourage business firms to be innovation-oriented and to encourage universities to develop, beyond their traditional teaching mission, also their research performance and their capabilities to transfer research results and new knowledge to convert them into commercially relevant innovations. The role of government was to create a suitable legal environment and proper incentives to stimulate and support change and to enable collaborations between Public and Private Sector actors. Despite all efforts in launching relevant programmes, the competency and attractiveness of universities for strategic research partnerships with the private sector remained heterogeneous and partially unsatisfactory because of shortcomings in their knowledge base and their capability to act as well-performing research partners in collaborative projects. In 2004 Hungary established a new complementary programme which addressed particularly these shortcomings, the Pázmány Péter – Regional University Knowledge Centre programme. This paper describes shortly the programme and then investigates the experiences of two initial calls. This Public-Private-Partnership model, where the state is not the single supporter of the programme, the participating Private Sector actors provide complementary funding. In addition, the centres can also attract external funding from various other sources. In addition, Private Sector enterprises make advanced technical equipment available for use by members and non-members. By the first experiences this programme is a good frame to support overcoming on one of the failure of the system, weak knowledge distribution capability. This initiative, the Pázmány Péter programme provides a potentially transferable example for other countries with shortcomings similar to those of Hungary’s National

The results are presented of a multi-centre randomly controlled trial of fast neutron irradiation and mega-voltage X-rays in the treatment of patients with locally advanced squamous cell carcinoma of the head and neck region. No significant difference was observed in local tumour control rates. Salvage surgery was performed in a similar number of patients in the two groups. Late morbidity was also similar in the two treatment groups. Patients in a subgroup with cancer of the larynx treated by photons had a significantly better survival than those in the neutron treated group. (Auth.)

Radiobiological, pharmacokinetic and biodistribution studies are of paramount importance for drug development and more so in the development of newer radiation modulators. Radiobiological studies have now graduated from simple cell survival and viability assays to more complex molecular and imaging studies to study radiation modulation both in in-vitro and in-vivo models. Tata Memorial Centre and its research centre (ACTREC) is a premiere cancer centre in India dedicated to cancer research. The Department of Radiation Oncology treats approximately 7000 new patients in a year and is uniquely placed to do both translational radiation and clinical research in the field of drug development. The Clinical Biology Lab of the Department of Radiation Oncology at ACTREC in collaboration with other labs at ACTREC has standardized cell survival assays, DNA damage assays such as Gamma H2AX assay (by flow as well as confocal microscopy), Micronuclei assay and COMET assays using CASP software for quantification. We have also done apoptotic assays. These assays have been conducted for development newer drug formulations (for e.g liposomal radiosensitizers). We also have a strong imaging division having sophisticated microscopes (confocal and single molecule super resolution microscopes) for in-vitro optical imaging and a dedicated preclinical PET/CT/SPECT for in-vivo imaging. The clinical 3T MRI and PET/CT is being used to study the effect of hypoxia in various cancers

Highlights: • We found variation in early performance measures across screening centres. • Radiologists’ performance may play a key role in the variability. • Potential to improve the effectiveness of breast cancer screening programs. • Continuous surveillance of screening centres and radiologists is essential. - Abstract: Background: Recall for assessment in mammographic screening entails an inevitable number of false-positive screening results. This study aimed to investigate the variation in the cumulative risk of a false positive screening result and the positive predictive value across the screening centres in the Norwegian Breast Cancer Screening Program. Methods: We studied 618,636 women aged 50–69 years who underwent 2,090,575 screening exams (1996–2010. Recall rate, positive predictive value, rate of screen-detected cancer, and the cumulative risk of a false positive screening result, without and with invasive procedures across the screening centres were calculated. Generalized linear models were used to estimate the probability of a false positive screening result and to compute the cumulative false-positive risk for up to ten biennial screening examinations. Results: The cumulative risk of a false-positive screening exam varied from 10.7% (95% CI: 9.4–12.0%) to 41.5% (95% CI: 34.1–48.9%) across screening centres, with a highest to lowest ratio of 3.9 (95% CI: 3.7–4.0). The highest to lowest ratio for the cumulative risk of undergoing an invasive procedure with a benign outcome was 4.3 (95% CI: 4.0–4.6). The positive predictive value of recall varied between 12.0% (95% CI: 11.0–12.9%) and 19.9% (95% CI: 18.3–21.5%), with a highest to lowest ratio of 1.7 (95% CI: 1.5–1.9). Conclusions: A substantial variation in the performance measures across the screening centres in the Norwegian Breast Cancer Screening Program was identified, despite of similar administration, procedures, and quality assurance requirements.

Breast cancer is the most common cancer among females worldwide in general and in the Middle East and the North African region (MENA region) in particular. Management of breast cancer in the MENA region faces a lot of challenges, which include younger age at presentation, aggressive behaviour, lack of national breast screening programmes and lack of reliable data registries as well as socioeconomic factors. These factors make applying the international guidelines for breast cancer management very challenging. The aim of this project is to explore the need for a regional breast cancer guideline as well as to screen the clinical practice of breast cancer management in the MENA region. Three web-based designed surveys were sent to more than 600 oncologists in the MENA region from the period of August 2013 to October 2014. Full descriptive data and information regarding the application of international breast cancer guidelines were collected. The software was using the IP address to prevent duplication of collected data. Descriptive analysis and results were shown as numbers and percentages. During the period of the survey, 104 oncologists responded, representing around an 11% response rate. The majority of replies came from Egypt (59 responses (59%)), followed by Saudi Arabia (ten responses (9.6%)). Fifty-one per cent of responders had more than ten years of experience, and further 31.7% had 5-10 years of experience. Seventy-four per cent were working in governmental hospitals, which is our target sector. There was a major defect in having a genetic counsel unit (78.8% declared an absence of this service), presence of a national breast screening programme (55.8% declared an absence of this service), performing sentinel lymph node biopsy (43.3% declared an absence of this service). The need for regional guidelines for the management of breast cancer was agreed upon by 90.6% of responders. There is a clear need to improve the management of breast cancer in the MENA

Background: Daily variations in bladder filling make conformal treatment of bladder cancer challenging. On-line adaptive radiotherapy with a choice of plans has been demonstrated to reduce small bowel irradiation in single institution trials. In order to support a multicentre feasibility clinical trial on adaptive radiotherapy for bladder cancer (TROG 10.01) a credentialing programme was developed for centres wishing to participate. Methods: The credentialing programme entails three components: a facility questionnaire; a planning exercise which tests the ability of centres to create three adaptive plans based on a planning and five cone beam CTs; and a site visit during which image quality, imaging dose and image guidance procedures are assessed. Image quality and decision making were tested using customised inserts for a Perspex phantom (Modus QUASAR) that mimic different bladder sizes. Dose was assessed in the same phantom using thermoluminescence dosimetry (TLD). Results: All 12 centres participating in the full credentialing programme were able to generate appropriate target volumes in the planning exercise and identify the correct target volume and position the bladder phantom in the phantom within 3 mm accuracy. None of the imaging doses exceeded the limit of 5 cGy with a CT on rails system having the lowest overall dose. Conclusion: A phantom mimicking the decision making process for adaptive radiotherapy was found to be well suited during site visits for credentialing of centres participating in a clinical trial of adaptive radiotherapy for bladder cancer. Combined with a planning exercise the site visit allowed testing the ability of centres to create adaptive treatment plans and make appropriate decisions based on the volumetric images acquired at treatment.

YE Shenglong

2013-01-01

Full Text Available Loco-regional therapy, which uses imaging technologies to facilitate targeted delivery of therapeutic agents to cancers, has emerged as the most commonly used non-surgical treatment for primary liver cancer. Since the theory of loco-regional therapy was introduced, various strategies have been developed and successfully applied in clinic, including interventional radiology methods (mainly transarterial chemoembolization and local ablative methods (such as intratumoral ethanol injection, radiofrequency ablation, microwave coagulation, laser-induced thermal therapy, high-intensity focused ultrasound, and cryotherapy. TACE has been widely applied to treat inoperable liver cancers at intermediate and advanced stages, while the local ablative therapies have proven more suitable for small (＜5 cm liver cancers. However, choosing the appropriate loco-regional therapy strategy should be carried out on an individual basis, considering the patient's particular disease condition and characteristics. To help guide such treatment decisions, this review highlights the principal indications, theory, techniques, and reported efficacies of the various loco-regional therapy strategies.

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

2010-01-01

Background Benchmarking is one of the methods used in business that is applied to hospitals to improve the management of their operations. International comparison between hospitals can explain performance differences. As there is a trend towards specialization of hospitals, this study examines the benchmarking process and the success factors of benchmarking in international specialized cancer centres. Methods Three independent international benchmarking studies on operations management in cancer centres were conducted. The first study included three comprehensive cancer centres (CCC), three chemotherapy day units (CDU) were involved in the second study and four radiotherapy departments were included in the final study. Per multiple case study a research protocol was used to structure the benchmarking process. After reviewing the multiple case studies, the resulting description was used to study the research objectives. Results We adapted and evaluated existing benchmarking processes through formalizing stakeholder involvement and verifying the comparability of the partners. We also devised a framework to structure the indicators to produce a coherent indicator set and better improvement suggestions. Evaluating the feasibility of benchmarking as a tool to improve hospital processes led to mixed results. Case study 1 resulted in general recommendations for the organizations involved. In case study 2, the combination of benchmarking and lean management led in one CDU to a 24% increase in bed utilization and a 12% increase in productivity. Three radiotherapy departments of case study 3, were considering implementing the recommendations. Additionally, success factors, such as a well-defined and small project scope, partner selection based on clear criteria, stakeholder involvement, simple and well-structured indicators, analysis of both the process and its results and, adapt the identified better working methods to the own setting, were found. Conclusions The improved

Background. Due to specific war and post-war situation in Balkan region, differences in the number, type, development, biological course, treatment of malignant tumours and its outcome are possible. In order to perceive the situation realistically, it is necessary to gather continuously exact data about malignant tumours and compare them with the data from other European and world countries.The aim of the study was to collect and analyse the data on cancer incidence in the region of Sarajevo city, which represents a symbol of difficult times in the recent past, and to compare it to the incidence in the neighbouring countries. Patients and methods. Data on all newly diagnosed cancer cases, permanent residents of Sarajevo Canton, in the years 1999 and 2000 were collected. Crude incidence rate has been calculated according to the years observed, gender and localizations of the disease The data were compared to the cancer registries of Slovenia and Croatia and were observed in the light of specific local situation. Results. The crude cancer incidence of all sites but skin was the highest in both years and by both genders in Croatia. The incidence of the most common tumours (lung and breast cancer) was similar in all three countries. The differences in the incidence between both genders in the Sarajevo canton were registered in laryngeal and urinary bladder cancer, as well as in bone and cartilage sarcoma. Cervical cancer had extremely high incidence and was high up on the incidence list in the Sarajevo canton, which correlates with the data in developing countries. The incidence of other tumours in the post-war period is reaching expected numbers. Conclusions. It is difficult to identify whether the war and post-war stress, irregular and insufficient nutrition during and after the siege of the city of Sarajevo or some other factor influenced the cancer incidence among exposed population. The prevalence of smoking in the whole region is extremely high, in Bosnia and

Climate, like weather, has no limits. Therefore the World Meteorological Organization (WMO), a specialized United Nations organization, has established a three-level infrastructure to better serve its member countries. This structure comprises Global Producing Centres for Long-range Forecasts (GPCs), Regional Climate Centres (RCCs) and National Meteorological or Hydrometeorological Services (NMHSs), in most cases representing their countries in WMO governance bodies. The elements of this infrastructure are also part of and contribute to the Global Framework for Climate Services (GFCS) agreed to be established by World Climate Conference 3 (WCC-3) and last year's Sixteenth World Meteorological Congress (WMO Cg-XVI). RCCs are the core element of this infrastructure at the regional level and are being establish in all WMO Regional Associations (RAs), i.e. Africa (RA I); Asia (II); South America (III); North America, Central America and the Caribbean (IV); South-West Pacific (V); Europe (VI). Addressing inter-regional areas of common interest like the Mediterranean or the Polar Regions may require inter-regional RCCs. For each region the RCCs follow a user driven approach with regard to governance and structure as well as products generated for the users in the respective region. However, there are common guidelines all RCCs do have to follow. This is to make sure that services are provided based on best scientific standards, are routinely and reliably generated and made available in an operational mode. These guidelines are being developed within WMO and make use of decade-long experience gained in the business of operational weather forecast. Based on the requirements of the 50 member countries of WMO RA VI it was agreed to establish the WMO RCC as a network of centres of excellence that create regional products including long-range forecasts that support regional and national climate activities, and thereby strengthen the capacity of WMO Members in the region to

Full Text Available Abstract Eighteen international cancer centres responded to a questionnaire designed to determine clinic practices regarding the management of Hereditary Non-Polyposis Colorectal Cancer (HNPCC. Areas covered include definition, clinical intakes, pre-genetic testing for microsatellite instability (MSI or expression of mismatch repair (MMR genes by immunohistochemistry (IHC, mutational analysis, consent practices, counselling, surveillance planning, and surgical decision making. In the absence of a firm evidence base, some management practices were variable, with local access to funding and other resources being influential. More consistent responses were evident for management practices with a stronger evidence base from previous clinical research. This document provides important information to guide the management of HNPCC patients, allow comparisons to be made between the approaches of various clinics to HNPCC families, and define management issues that need to be addressed in clinical research.

The most advanced countries are beginning to apply a new type of radiotherapy, more powerful and specific than that currently in use, based on the use of protons. The first Spanish centre to be equipped with a complex facility of this type will be the Valencian Institute of Medical Physics, which will be able to treat 2,000 patients a year. This radiotherapy technique is especially suitable for the treatment of cancers in children and cerebral and ocular cancers, which affect some 8,000 patients a year in Spain. (Author)

The effect of working in an oncology environment on nurses has been widely researched but the experiences of non-clinical staff such as ancillary workers in the oncology environment have rarely been examined. This exploratory study had three aims: to explore ancillary workers' understandings of cancer, their experiences of working in a Cancer Centre and their training and support needs. Working within a naturalistic paradigm, a descriptive exploratory design was utilised employing in-depth interviews and drawing on aspects of grounded theory for data analysis. Findings indicated that these ancillary workers lacked an in-depth understanding of cancer. The experience of working in a Cancer Centre appeared to bring both costs and benefits to these ancillary workers. These ancillary workers enjoyed the level of contact they have with patients in a Cancer Centre and subsequently ascribed great value to their jobs. However, they felt that health-care professional colleagues did not always value their contribution to the care of patients. There are implications for nurses and other health-care staff working in oncology alongside these ancillary staff in terms of valuing and supporting them in the work that they do.

The total number of malignant neoplasms included in this study 53,566 cases(14.1%) among 379,582 patients from 1984 to 1993. On sex, females with 51.3% were much more than males with 48.7%. The highest proportion of cancer patients by age was 35.0% in males and 28.4% in females, respectively for 50-59 age group. The most frequent primary site among males was found to be stomach with 33.2%, followed by liver(15.1%), lung(14.9%), esophagus(5.3%) and larynx(3.3%). In females, the first order was uterine cervix with 37.8%, followed by stomach(16.5%), breast(14.8%), thyroid gland(4.3%) and lung (3.8%). The proportion of malignant neoplasms diagnosed by histology made up 67.0%, whereas 20.2% was diagnosed by clinical investigation(X-ray, CT, MRI etc). Among the cancer patients initially diagnosed in this hospital, the proportion of malignant neoplasms by the extent of disease was 3.7% for patient with carcinoma-in-situ, 58.7% for patients with localized involvement, 18.4% for patients with regional involvement and 11.1% for patients with distant involvement. Among the cancer patients initially treatment in this hospital, the proportion of malignant neoplasms by the method of treatment was 27.5% for surgery, 22.5% for radiotherapy and 30.1% for chemotherapy. The proportion of cancer patients traced to death was only to 3.6%, 1,944 cases. Among them, 72.5% survived for less than 1 year. 17 figs, 7 tabs, 28 refs. (Author).

The aims of this paper are three-fold: (1) to summarize the current epidemiological data on oral cancer in Libya as reported in the published literature and as compared to other national oral cancer rates in the region; (2) to present both the history of the early development, and future goals, of population-based oral cancer tumor registries in Libya as they partner with the more established regional and international population-based cancer tumor registries; and, (3) to offer recommendations that will likely be required in the near future if these nascent, population-based Libyan oral cancer registries are to establish themselves as on-going registries for describing the oral cancer disease patterns and risk factors in Libya as well as for prevention and treatment. This comprehensive literature review revealed that the current baseline incidence of oral cancer in Libya is similar to those of other North Africa countries and China, but is relatively low compared to the United Kingdom, the United States, and India. The recently established Libyan National Cancer Registry Program, initiated in 2007, while envisioning five cooperating regional cancer registries, continues to operate at a relatively suboptimal level. Lack of adequate levels of national funding continue to plague its development…and the accompanying quality of service that could be provided to the Libyan people.

The evaluation of national cancer plans is an important aspect of their implementation. For this evaluation, the principal actors in the field (doctors, nurses, etc.) as well as decision-makers must have access to information that is reliable, synthetic and easy to interpret, and which reflects the implementation process in the field. We propose here a methodology to make this type of information available in the context of reducing inequalities with regard to access to healthcare for patients with lung cancer in the region of Burgundy. We used the national medico-administrative DRG-type database, which gathers together all hospital stays. By using this database, it was possible to identify and reconstruct the care management history of these patients. That is, by linking together all attended hospitals, sorted chronologically. Eligible patients were at least 18 years old, whatever the gender and had undergone surgery for their lung cancer. They had to be residents of Burgundy at the time of the first operation between 2006 and 2008. Patient's pathway was defined as the sequence of all attended hospitals (hospital stays) during the year of follow up linked together using an anonymised patient identifier. We then constructed a pathway typology of pathway using an unsupervised clustering method, and conducted a spatial analysis of this typology. Between 2006 and 2008, we selected 495 patients in the 4 administrative departments of the Burgundy region. They accounted for a total of 3821 stays during the year of follow-up. There were 393 men (79%) and the mean age was 64 (95% confidence interval: 63-65) years. We reconstructed 94 pathways (about five per patient). Here, neighbourhood's cares accounted for 41% of them, while 44% included a surgical intervention outside the region of Burgundy. We constructed a pathway typology with five classes. Spatial analysis showed that the vast majority of initial surgeries took place in the major regional centres. The construction

Few studies deal with the association of socioeconomic and health system resource variables with cancer survival at the Italian regional level, where the greatest number of decisions about social and health policies and resource allocations are taken. The present study aimed to describe the causal relationships between socioeconomic and health system resource factors and regional cancer survival and to compute the expected cancer survival at provincial, regional and area levels. Age-standardized relative survival at 5 years from diagnosis of cases incident in 1995-1998 and followed up to 2004 were derived by gender for 11 sites from the Italian Association of Cancer Registries data bank. The socioeconomic and health system resource variables, describing at a regional level the macro-economy, demography, labor market, and health resources for 1995-2005, came from the Health for All database. A principal components factor analysis was applied to the socioeconomic and health system resource variables. For every site, linear regression models were computed considering the relative survival at 5 years as a dependent variable and the principal components factor analysis factors as independent variables. The factors described the socioeconomic and health-related features of the regional systems and were causally related to the characteristics of the patient taken in charge. The models built by the factors allowed computation of the expected relative survival at 5 years with very good concordance with those observed at regional, macro-regional and national levels. In the regions without any cancer registry, survival was coherent with that of neighboring regions with similar socioeconomic and health system resources characteristics. The models highlighted the causal correlations between socioeconomic and health system resources and cancer survival, suggesting that they could be good evaluation tools for the efficiency of the resources allocation and use.

To investigate the value of second-opinion evaluation of multiparametric prostate magnetic resonance imaging (MRI) by subspecialised uroradiologists at a tertiary centre for the detection of significant cancer in transperineal fusion prostate biopsy. Evaluation of prospectively acquired initial and second-opinion radiology reports of 158 patients who underwent MRI at regional hospitals prior to transperineal MR/untrasound fusion biopsy at a tertiary referral centre over a 3-year period. Gleason score (GS) 7-10 cancer, positive predictive value (PPV) and negative (NPV) predictive value (±95 % confidence intervals) were calculated and compared by Fisher's exact test. Disagreement between initial and tertiary centre second-opinion reports was observed in 54 % of cases (86/158). MRIs had a higher NPV for GS 7-10 in tertiary centre reads compared to initial reports (0.89 ± 0.08 vs 0.72 ± 0.16; p = 0.04), and a higher PPV in the target area for all cancer (0.61 ± 0.12 vs 0.28 ± 0.10; p = 0.01) and GS 7-10 cancer (0.43 ± 0.12 vs 0.2 3 ± 0.09; p = 0.02). For equivocal suspicion, the PPV for GS 7-10 was 0.12 ± 0.11 for tertiary centre and 0.11 ± 0.09 for initial reads; p = 1.00. Second readings of prostate MRI by subspecialised uroradiologists at a tertiary centre significantly improved both NPV and PPV. Reporter experience may help to reduce overcalling and avoid overtargeting of lesions. (orig.)

After an overview of the energy sector in the world (consumption growth, share of the different energies, main consuming countries, evolution of the energy mix, perspectives) and in France (energy consumption, energy production, jobs, trade balance, research policy and organisation), this publication proposes an overview of energy industries in the Centre-Val de Loire region. It provides some data such as regional consumption, share in the national energy production, jobs and employment structure. The next part proposes a sector-based approach by evoking a strong expertise in the oil and gas industry, by describing a rich industrial tissue about electro-nuclear energy (various activities, specialised urban areas, job creations in nuclear plants, education and training, research lead by private consultants), and by outlining that the territory is suitable for the development of renewable energies (solar, wind, biomass, and geothermal energies, energy storage, R and D, education)

With the consumption of fossil fuels, the resources essential to Man's survival are being rapidly contaminated. A sustainable future may be achieved by the use of renewable energies, allowing countries without non-renewable energy resources to guarantee energetic sovereignty. Using bioenergy may mean a steep reduction and/or elimination of the external dependency, enhancing the countries' capital and potentially reducing of the negative effects that outcome from the use of fossil fuels, such as loss of biodiversity, air, water, and soil pollution, … This work's main focus is to increase bioenergy use in the centre region of Portugal by allying R&D to facilitate determination of bioenergy availability and distribution throughout the study area.This analysis is essential, given that nowadays this knowledge is still very limited in the study area. Geographic Information Systems (GIS) was the main tool used to asses this study, due to its unseeingly ability to integrate various types of information (such as alphanumerical, statistical, geographical, …) and various sources of biomass (forest, agricultural, husbandry, municipal and industrial residues, shrublands, used vegetable oil and energy crops) to determine the bioenergy potential of the study area, as well as their spatial distribution. By allying GIS with multi-criteria decision analysis, the initial table-like information of difficult comprehension is transformed into tangible and easy to read results: both intermediate and final results of the created models will facilitate the decision making process. General results show that the major contributors for the bioenergy potential in the Centre Region of Portugal are forest residues, which are mostly located in the inner region of the study area. However, a more detailed analysis should be made to analyze the viability to use energy crops. As a main conclusion, we can say that, although this region may not use only this type of energy to be completely

Cancer is one of the leading causes of deaths worldwide (1); in 2012, an estimated 65% of all cancer deaths occurred in the less developed regions of the world (2). In the Caribbean region, cancer is the second leading cause of mortality, with an estimated 87,430 cancer-related deaths reported in 2012 (3). The Pan American Health Organization defines the Caribbean region as a group of 27 countries that vary in size, geography, resources, and surveillance systems.* CDC calculated site- and sex-specific proportions of cancer deaths and age-standardized mortality rates (ASMR) for 21 English- and Dutch-speaking Caribbean countries, the United States, and two U.S. territories (Puerto Rico and the U.S. Virgin Islands [USVI]), using the most recent 5 years of mortality data available from each jurisdiction during 2003-2013. The selection of years varied by availability of the data from the countries and territories in 2015. ASMR for all cancers combined ranged from 46.1 to 139.3 per 100,000. Among males, prostate cancers were the leading cause of cancer deaths, followed by lung cancers; the percentage of cancer deaths attributable to prostate cancer ranged from 18.4% in Suriname to 47.4% in Dominica, and the percentage of cancer deaths attributable to lung cancer ranged from 5.6% in Barbados to 24.4% in Bermuda. Among females, breast cancer was the most common cause of cancer deaths, ranging from 14.0% of cancer deaths in Belize to 29.7% in the Cayman Islands, followed by cervical cancer. Several of the leading causes of cancer deaths in the Caribbean can be reduced through primary and secondary preventions, including prevention of exposure to risk factors, screening, early detection, and timely and effective treatment.

Teamwork is essential for addressing many of the challenges that arise in the coordination and delivery of cancer care, especially for the problems that are presented by patients who cross geographic boundaries and enter and exit multiple health care systems at various times during their cancer care journeys. The problem of coordinating the care of patients with cancer is further complicated by the growing number of treatment options and modalities, incompatibilities among the vast variety of technology platforms that have recently been adopted by the health care industry, and competing and misaligned incentives for providers and systems. Here we examine the issue of regional care coordination in cancer through the prism of a real patient journey. This article will synthesize and elaborate on existing knowledge about coordination approaches for complex systems, in particular, in general and cancer care multidisciplinary teams; define elements of coordination derived from organizational psychology and human factors research that are applicable to team-based cancer care delivery; and suggest approaches for improving multidisciplinary team coordination in regional cancer care delivery and avenues for future research. The phenomenon of the mobile, multisystem patient represents a growing challenge in cancer care. Paradoxically, development of high-quality, high-volume centers of excellence and the ease of virtual communication and data sharing by using electronic medical records have introduced significant barriers to effective team-based cancer care. These challenges urgently require solutions. PMID:27650833

Colorectal cancer is the second most frequent cancer in Malaysia. Nevertheless, there is little information on treatment and outcomes nationally. We aimed to determine the demographic, clinical and treatment characteristics of colorectal cancer patients treated at the University Malaya Medical Centre (UMMC) as part of a larger project on survival and quality of life outcomes. Medical records of 1,212 patients undergoing treatment in UMMC between January 2001 and December 2010 were reviewed. A retrospective-prospective cohort study design was used. Research tools included the National Cancer Patient Registration form. Statistical analysis included means, standard deviations (SD), proportions, chi square, t-test/ ANOVA. P-value significance was set at 0.05. The male: female ratio was 1.2:1. The mean age was 62.1 (SD12.4) years. Patients were predominantly Chinese (67%), then Malays (18%), Indians (13%) and others (2%). Malays were younger than Chinese and Indians (mean age 57 versus 62 versus 62 years, p<0.001). More females (56%) had colon cancers compared to males (44%) (p=0.022). Malays (57%) had more rectal cancer compared to Chinese (45%) and Indians (49%) (p=0.004). Dukes' stage data weres available in 67%, with Dukes' C and D accounting for 64%. Stage was not affected by age, gender, ethnicity or tumor site. Treatment modalities included surgery alone (40%), surgery and chemo/radiotherapy 32%, chemo and radiotherapy (8%) and others (20%). Significant ethnic differences in age and site distribution, if verified in population-based settings, would support implementation of preventive measures targeting those with the greatest need, at the right age.

Observed regional differences in breast cancer incidence could provide valuable clues to the etiology of this disease. The pattern of historically higher breast cancer rates among residents of California's San Francisco Bay and Southern Coastal areas is evident in the disease experience among members of the California Teachers Study. This large cohort study has followed female professional school employees for cancer incidence since 1995 and has collected extensive information on breast cancer risk factors. Between 1996 and 1999, invasive breast cancer was diagnosed in 1562 of the 115,611 cohort members who could be geocoded to a California address in 1995 and who had no previous breast cancer diagnosis. Adjusted hazard rate ratios (HRs) were estimated through multivariate Cox proportional hazards modeling. Rates were higher for cohort members in the San Francisco Bay area (HR = 1.22; 95% confidence interval = 1.06-1.40) and Southern Coastal area (1.16; 1.04-1.30) compared with those in the rest of California. The distributions of variables representing socioeconomic status, urbanization, and personal risk factors were consistent with higher risks for cohort members residing in the San Francisco Bay and Southern Coastal areas. Adjustment for these factors, however, did not explain regional differences in incidence, resulting in HRs that remained elevated for these 2 areas. Regional differences in breast cancer incidence in this large, well-defined cohort are not easily explained by known risk factors.

Cancer is a disease of gradual increase in incidence overall the world. Kurdistan Region in Iraq has been exposed to several carcinogenic hazards. There are few reports about the increased risk of cancer in different cities in Iraq. These reports did not cover Kurdistan region. The aim of this paper was to study cancer incidence and to identify possible risks of cancer in this region. Cancer registries from 9 hospitals in three cities of Kurdistan were used as a source of data. Information on these cases was subjected to careful verification regarding repetition, place of residence and other possible errors. Overall registered cases in 2007, 2008 and 2009 were 1444, 2081, 2356 respectively. 49% of registered cases were males and 51% were female. The Age Standardized Rate of cancer was 89.83/100 000 among male and 83.93/100 000 among female. The results showed major variation in incidence rates of different types of cancer in the three governorates of Kurdistan. Furthermore, there was evidence of increased risks of cancer in Kurdistan Region in Iraq. Hematological malignancies were the most common cancer among male (21.13% of all cancer in males) and second most common in female (18.8% of all cancer in female), only exceeded by breast cancer. To reach sound conclusions about extent and determinants of cancer in Kurdistan, enormous multi-spectrum efforts are now needed.

The Hong Kong Special Administrative Region (HKSAR) of the People's Republic of China (PRC) has seen significant changes in its trauma service over the last ten years including the implementation of a regional trauma system. The author's institution is one of the five trauma centres designated in 2003. This article reports our initial clinical experience. A prospective single-centre trauma registry from January 2004 to December 2008 was reviewed. The primary clinical outcome measure was hospital mortality. The Trauma and Injury Severity Score (TRISS) methodology was used for bench-marking with the North America Major Trauma Outcome Study (MTOS) database. There were 1451 patients. The majority (83.9%) suffered from blunt injury. The overall mortality rate was 7.8%. Severe injury, defined as the Injury Severity Score > 15, occurred in 22.5% of patients, and was associated with a mortality rate of 31.6%. A trend of progressive improvement was noted. The M-statistic was 0.99, indicating comparable case-mix with the MTOS. The Z- and W-statistics of each individual year revealed fewer, but not significantly so, number of survivors than expected. Trauma centre designation was feasible in the HKSAR and was associated with a gradual improvement in patient care. Trauma system implementation may be considered in regions equipped with the necessary socio-economic and organizational set-up.

Marked unexplained national variations in incidence rates of kidney cancer have been observed for decades in Europe. To investigate geographic variations at the regional level and identify European regions with high incidence rates of kidney cancer. Regional- and national-level incidence data were extracted from the Cancer Incidence in Five Continents databases, local cancer registry databases, and local published reports. World population age-standardised rates (ASRs) were calculated for the periods 2003-2007 and 1988-1992. Rates by period and sex were compared using map visualisation. During 2003-2007, the highest ASR was found in the Plzen region, Czech Republic (31.4/100,000 person-years in men). Other regions of the Czech Republic had ASRs of 18.6-27.5/100,000 in men, with a tendency for higher rates in regions south of Prague. Surrounding regions, including eastern Germany and regions of Slovakia and Austria, had medium-to-high incidence rates (13.0-16.8/100,000 in men). Three other areas in Europe showed higher incidence rates in men compared with the rest of the continent: Lithuania, Estonia, Latvia, and Belarus (15.0-17.6/100,000); Iceland (13.5/100,000), and northern Italy (up to 16.0/100,000). Similar regional differences were observed among women, with rates approximately half of those observed in men in the same region. In general, these regional geographic variations remained stable over the periods 1988-1992 and 2003-2007, although higher incidence rates were detected in the Baltic countries in 2003-2007. Several European regions show particularly high rates of kidney cancer incidence. Large variations were observed within countries covered by national health-care systems, implying that overdetection is not the major factor. We present regional geographic variations in kidney cancer incidence rates in Europe. We highlight several regions with high incidence rates where further studies should be conducted for cancer control and prevention. Copyright �

Effects of unstratified and centre-stratified randomization in multi-centre clinical trials.

Anisimov, Vladimir V

2011-01-01

This paper deals with the analysis of randomization effects in multi-centre clinical trials. The two randomization schemes most often used in clinical trials are considered: unstratified and centre-stratified block-permuted randomization. The prediction of the number of patients randomized to different treatment arms in different regions during the recruitment period accounting for the stochastic nature of the recruitment and effects of multiple centres is investigated. A new analytic approach using a Poisson-gamma patient recruitment model (patients arrive at different centres according to Poisson processes with rates sampled from a gamma distributed population) and its further extensions is proposed. Closed-form expressions for corresponding distributions of the predicted number of the patients randomized in different regions are derived. In the case of two treatments, the properties of the total imbalance in the number of patients on treatment arms caused by using centre-stratified randomization are investigated and for a large number of centres a normal approximation of imbalance is proved. The impact of imbalance on the power of the study is considered. It is shown that the loss of statistical power is practically negligible and can be compensated by a minor increase in sample size. The influence of patient dropout is also investigated. The impact of randomization on predicted drug supply overage is discussed. Copyright © 2010 John Wiley & Sons, Ltd.

Full Text Available BACKGROUND Lung cancer is the most common cancer worldwide since 1985, both in terms of incidence and mortality. Globally, lung cancer is the largest contributor to new cancer diagnoses and cancer-related deaths. The aim of the study is to study the clinical, radiological and pathological features of patients diagnosed with lung carcinoma. MATERIALS AND METHODS This observational and cross-sectional study was conducted at Himalayan Institute of Medical Sciences (HIMS, which is a large tertiary centre of Uttarakhand on 77 patients of proven lung carcinoma diagnosed over a period of February 2015 to March 2016. The clinical history of the patients was recorded in detail along with the radiological and pathological findings. Ethical clearance certificate was obtained from the ethical committee. RESULTS The study included a total of 77 patients of proven lung carcinoma. Out of the total patients, 70 were males and 7 were females. Cough was the most common symptom. Smoking was the commonest addiction (89.61% in the patients. Non-small cell carcinoma was seen in 59 patients while small cell carcinoma was seen in 23.38% of the cases. Amongst the total patients of non-small cell carcinoma, the maximum number of patients had squamous cell carcinoma (56%. CONCLUSION This study showed that smoking is a principle risk factor in causation of lung carcinoma. Lung cancer should be suspected in an old person presenting with cough and other symptoms such as malaise, weight loss etc. Squamous cell carcinoma is still the most common histological type of lung cancer in India.

Full Text Available Regional development within the Ruhr district – from the formally centre of the coal and steel industry to a centre of tertiary services. The Ruhrgebiet (Ruhr district is an urban agglomeration in the western part of Germany with a population of approximately 5.3 Million, covering an area of 4.435 km². It’s part of the metropolitan area of Rhine-Ruhr with more than 10 Million inhabitants living in an area of about 10.000 km².The black coal resources, deposited during the carboniferous area form the natural backbone for the development of the largest region of coal, iron, and steel industry in Europe. The economy of the Ruhrgebiet was unidirectional dominated for more than 150 years by four heavy industry sectors, black coal, steel, chemical industry and energy production. But later, when petroleum and natural gas and cheaper imported black coal conquered the German market and, as well, steel could be produced at a reduced rate elsewhere in the world the booming producing industry quasi collapsed. Thus, the Region is characterized by an above average unemployment since the mid 70ies. More than 50% of the 1 Million jobs in the region were lost, while only 300.000 new jobs could be added within the service sector between 1980 and 2002. The economic and social structural change within the Ruhr district is primarily based on the expansion of services like advertisement, science, development, transport logistics, consulting, and design. But also the cultural and tourist branches are characterized by growing figures. The BIP, produced within the Ruhrgebiet, is about 26% of the BIP of North-Rhine-Westphalia or 6% of Germany’s BIP. In comparison, the metropolitan area of São Paulo produces 17% of the national BIP of Brazil.

Colorectal cancer (CRC) is one of the major malignancies in the world. In Malaysia, CRC is fast becoming the commonest cause of cancer death. Its etiology is complex, involving both environmental and genetic factors. This study looked at the profile and outcome of five-year follow-up of patients with CRC. Retrospective case review study done on CRC patients at University Kebangsaan Malaysia Medical Centre (UKMMC), Kuala Lumpur, Malaysia. Patientsandapos; socio-demographic characteristics, modalities of treatment, cancer characteristics and outcome at 5-year follow up were extracted from the case records. A total of 107 case records of patients were analyzed. Peak age of CRC presentation was 40-69 years (71.1%). Male to female ratio was 1.2:1 with Chinese predominance (52.3%). Anaemia and its related symptoms including per rectal bleeding was the commonest clinical presentation. The median duration of clinical presentation was 13 weeks (IQR 21.8). More than two-thirds presented as non-emergency cases (69.2%). Most patients presented with Dukes C stage (40.2%). The overall 5-year survival rate was 40% with local recurrence rate of 19.6%. Metastasis after curative-intend treatment (surgery with adjuvant therapy) developed in 26% of patients. Lower recurrence (p = 0.016, OR = 0.205) and metastatic disease (p = 0.02, OR = 0.24) found among the Chinese patients. Almost half of the patients defaulted follow up care (43%), most often within the first year of treatment (22.4%) and the Chinese were the least likely to default (p= 0.04, OR = 0.45). Socio-demographic profile of CRC patients in UKMMC is comparable to Asia pacific region. Apparent delay in seeking treatment gives rise to poor overall survival and local recurrence rates.

Cancer incidence and mortality varies across region, sex and country's economic status. While most studies focused on global trends, this study aimed to describe and analyse cancer incidence and mortality in Asia, focusing on cancer site, sex, region and income status. Age-standardised incidence and mortality rates of cancer were extracted from the GLOBOCAN 2012 database. Cancer mortality to incidence ratios (MIRs) were calculated to represent cancer survival. The data were analysed based on the four regions in Asia and income. Cancer incidence rate is lower in Asia compared to the West but for MIR, it is the reverse. In Asia, the most common cancers in men are lung, stomach, liver, colorectal and oesophageal cancers while the most common cancers in women are breast, lung, cervical, colorectal and stomach cancers. The MIRs are the highest in lung, liver and stomach cancers and the lowest in colorectal, breast and prostate cancers. Eastern and Western Asia have a higher incidence of cancer compared to South-Eastern and South-Central Asia but this pattern is the reverse for MIR. Cancer incidence rate increases with country income particularly in colorectal and breast cancers but the pattern is the opposite for MIR. This study confirms that there is a wide variation in cancer incidence and mortality across Asia. This study is the first step towards documenting and explaining the changing cancer pattern in Asia in comparison to the rest of the world.

POSSIBILITIES OF THERAPY OF HER-2-POSITIVE REGIONAL BREAST CANCER

Full Text Available Breast cancer heads the list of malignant neoplasms in women. In this connection the regional forms of cancer are diagnosed in one fourth of the patients. The treatment of regional cancer begins with systemic therapy and aimed at gaining of state fit for operation. The choice of modern treatment strategy is based on determination of molecular subtype of the tumor. One of them is referred to HER-2-positive cancer, requiring the administration of additional targeted therapy. This form of cancer is referred to prognostically pejorative tumors, as it’s more aggressive, leads to fast metastasis and early death of the patients. The “golden standard” of systemic chemotherapy is defined as administration of docetaxel and trastuzumab,  and antracyclic drugs, which also prove to be efficient. However concomitant administration of trastuzumab and antracyclines is limited due to their cardiotoxicity. Chemotherapy is not always efficient and, upon recommendations both of Russian and international oncologists, radiotherapy is the next stage of treatment. The question about radiosensibility of HER-2-positive tumors is still open and worth studying. Addition of radiotherapy to regional cancer treatment regimen in combination with the targeted therapy and chemotherapy may contribute to obtaining better survival rate and disease control. There are still no clearly defined standard for the sequence of chemo-radiation therapy. Simultaneous  chemo-radiatiojn  therapy results in  reliably better loco-regional control of tumor and  enables to gain a  higher degree of pathomorphological response on the one hand, and it may result in development of serious adverse effects on the other hand. Striving for improvement of immediate results of antineoplastic therapy, including that of regional cancer, by combining various methods, one should keep in mind the increasing action toxicity, which may have a considerable impact on the patients’ quality of living

In this paper, automated extraction of metastatic liver cancer regions from abdominal contrast X-ray CT images is investigated. Because even in Japan, cases of metastatic liver cancers are increased due to recent Europeanization and/or Americanization of Japanese eating habits, development of a system for computer aided diagnosis of them is strongly expected. Our automated extraction procedure consists of following four steps; liver region extraction, density transformation for enhancement of cancer regions, segmentation for obtaining candidate cancer regions, and reduction of false positives by shape feature. Parameter values used in each step of the procedure are decided based on density and shape features of typical metastatic liver cancers. In experiments using practical 20 cases of metastatic liver tumors, it is shown that 56% of true cancers can be detected successfully from CT images by the proposed procedure. (author)

The Seabed 2030 SaWPac Centre (South and West Pacific Ocean Regional Data Assembly and Coordination Centre) has been formed to generate new high resolution ocean floor maps of the western and southern Pacific Ocean. The centre is part of the joint Nippon Foundation and the General Bathymetric Chart of the Oceans (GEBCO) initiative to produce a definitive map of the World Ocean floor by 2030, empowering the world to make policy decisions, use the ocean sustainability and undertake scientific research based on detailed bathymetric information of the Earth's seabed. The SaWPac Centre is based at NIWA Wellington (New Zealand) and includes a collaborative partnership with GNS Science and Land Information New Zealand. It is responsible for the region from South America to Australia, north of latitude 50°S to 10° north of the Equator and the western part of the Northern Pacific Ocean to Russia. The region includes the world's deepest trenches and also covers some of the remotest oceans where bathymetric data form existing ship tracks is spaced up to 100 km apart. The challenge for the SaWPac Centre is to collate and combine all the available bathymetric data from the numerous nations that have surveyed in the region. The centre will also promote efforts to collect new data and contribute to map products generated by the Seabed 2030 global mapping project.

Full Text Available Introduction: By the early 21st century the most common cancer of female genitals in Poland was cervical cancer. Now endometrial cancer ranks first. The aim of this study was to analyse the incidence and mortality of endometrial and cervical cancer among women in the Lodz region. Material and methods: Data on the incidence and mortality of endometrial and cervical cancer among inhabitants of the Lodz region were obtained from the National Cancer Registry and Bulletin of Cancer Cases in the Lodz region. The analysis covered ten consecutive years beginning in 2001. Results : The number of new cases reported in 2010 exceeded that observed in 2001 by 181. The standardized incidence rate of endometrial cancer increased by 6.3, while the standardized incidence rate of cervical cancer decreased by 1.4. Conclusions : In the years 2001-2010, the incidence of endometrial cancer increased by 88.3% and that of cervical cancer decreased by 6.5% among inhabitants of the Lodz region. In the years 2001-2010, mortality of endometrial cancer increased by 24.5% and that of cervical cancer decreased by 12.6%. In 2010, the highest crude incidence rates in the Lodz region of both endometrial and cervical cancer at 39.1 were recorded in the district town of Piotrków.

R&D networks and regional knowledge production: an agent-based simulation of the Austrian competence centres programme

Directory of Open Access Journals (Sweden)

Manuela Korber

2014-06-01

Full Text Available Publicly funded competence centres have gained high recognition for improving science-industry collaboration. With the requirement for long-term and geographically concentrated R&D, competence centres provide an environment for joint learning and transfer of “sticky” knowledge. The objective of this paper is to investigate how a competence centres programme affects knowledge production in the regional innovation system. In order to address this issue, we draw on a simulation approach and develop an agent-based model of the Vienna Life Sciences innovation system. Companies, research organisations and universities are heterogeneous agents that create scientific publications, patents, as well as high-tech jobs. Simulation runs refer to long-term scenarios regarding the level and duration of public funding. By addressing the complexities of knowledge interaction in the context of the “local buzz” versus “global pipelines” discussion, the results show the potential of empirically calibrated simulation models for ex-ante impact assessment in R&D policy.

Mapping of schistosomiasis and soil-transmitted helminthiasis in the regions of centre, East and West Cameroon.

Full Text Available BACKGROUND: Schistosomiasis and soil-transmitted helminthiasis (STH are widely distributed in Cameroon. Although mass drug administration (MDA of mebendazole is implemented nationwide, treatment with praziquantel was so far limited to the three northern regions and few health districts in the southern part of Cameroon, based on previous mapping conducted 25 years ago. To update the disease distribution map and determine where treatment with praziquantel should be extended, mapping surveys were conducted in three of the seven southern regions of Cameroon, i.e. Centre, East and West. METHODOLOGY: Parasitological surveys were conducted in April-May 2010 in selected schools in all 63 health districts of the three targeted regions, using appropriate research methodologies, i.e. Kato-Katz and urine filtration. PRINCIPAL FINDINGS: The results showed significant variation of schistosomiasis and STH prevalence between schools, villages, districts and regions. Schistosoma mansoni was the most prevalent schistosome species, with an overall prevalence of 5.53%, followed by S. haematobium (1.72% and S. guineensis (0.14%. The overall prevalence of schistosomiasis across the three regions was 7.31% (95% CI: 6.86-7.77%.

STH was more prevalent in the East region (46.57%; 95% CI: 44.41-48.75% in comparison to the Centre (25.12; 95% CI: 24.10-26.17% and West (10.49%; 95% CI: 9.57-11.51% regions. CONCLUSIONS/SIGNIFICANCE: In comparison to previous data, the results showed an increase of schistosomiasis transmission in several health districts, whereas there was a significant decline of STH infections. Based on the prevalence data, the continuation of annual or bi-annual MDA for STH is recommended, as well as an

Cancer-related mortality rates are higher in rural areas compared with urban regions. Whether there are corresponding geographical variations in radiotherapy utilisation rates (RURs) is the subject of this study. RURs for the regional centre of Geelong and rural areas of the Barwon South Western Region were calculated using a population-based database (2009). Lower RURs were observed for rural patients compared with the Geelong region for prostate cancer (15.7% vs 25.8%, P=0.02), rectal cancer (32.8% vs 44.7%, P=0.11), lymphoma (9.4% vs 26.2%, P=0.05), and all cancers overall (25.6% vs 28.9%, P=0.06). This lower rate was significant in men (rural, 19.9%; Geelong, 28.3%; P=0.00) but not in women (rural, 33.6%; Geelong, 29.7%; P=0.88). Time from diagnosis to radiotherapy was not significantly different for patients from the two regions. Tumour staging within the rural and Geelong regions was not significantly different for the major tumour streams of rectal, prostate and lung cancer (P=0.61, P=0.79, P=0.43, respectively). A higher proportion of tumours were unstaged or unstageable in the rural region for lung (44% vs 18%, P<0.01) and prostate (73% vs 57%, P<0.01) cancer. Lower RURs were observed in our rural region. Differences found within tumour streams and in men suggest a complexity of relationships that will require further study.

Objective: We aimed to improve diagnostic accuracy of 18 F-fluoro-2-deoxyglucose (FDG) PET/CT for gastric cancer with water gastric inflation. Materials and methods: 44 gastric cancer patients (M:F = 30:14, age ± std = 62.1 ± 14.5y) were enrolled before surgery. Fifty minutes after injection of FDG (0.14 mCi/kg body weight), whole body PET/CT was performed first and then regional PET/CT over gastric area was obtained 80 min post FDG injection after water gastric inflation. Diagnostic accuracies for loco-regional lesions were compared between whole body and regional PET/CT. Results: 48 primary tumors (23 EGC and 25 AGC) and 348 LN stations (61 metastatic and 287 benign) in 44 patients were investigated. Primary tumor sensitivity of whole body PET/CT (50% = 24/48) was significantly improved by regional PET/CT (75% = 36/48, p < 0.005). Sensitivity of whole body PET/CT (24.6% = 15/61) for LN metastasis was also significantly improved by regional PET/CT (36.1% = 22/61, p < 0.01), whereas specificity of whole body PET/CT (99.3% = 285/287) was not compromised by regional PET/CT (98.3% = 282/287, p > 0.05). Higher primary tumor FDG uptake in regional PET/CT indicated shorter progress-free survival (p = 0.0003). Conclusion: Diagnostic accuracy of whole body PET/CT for loco-regional disease of gastric cancer could be significantly improved by regional PET/CT after water gastric inflation and prognosis could be effectively predicted by primary tumor FDG uptake in regional PET/CT

Identifying and controlling a multiresistant pseudomonas aeruginosa outbreak in a latin-american cancer centre and its associated risk factors

Directory of Open Access Journals (Sweden)

Jorge Alberto Cortes

Full Text Available Pseudomonas aeruginosa is an important and frightening microorganism for patients suffering from cancer. Multiresistant P. aeruginosa (MRPA may appear as a consequence of exposure to multiple antibiotics or from a breakdown in infection control practices. This article reports an MRPA outbreak in a cancer treatment centre and the consequent case control study. Mechanical ventilation was identified as being the main risk factor for developing MRPA colonisation or infection; molecular analysis confirmed the outbreak. A multifaceted strategy was adopted, involving reinforcing hand-washing practices, contact isolation, antibiotic restriction and suction devices for mechanically-ventilated patients. MRPA was controlled and the outbreak ended. Such strategy may be effective in controlling MRPS in low-resource environments amongst high risk cancer patients.

To elicit patient stakeholders' experience and perspectives about patient-centred care. Qualitative. A large urban healthcare system. Four patient stakeholders who are prostate cancer survivors. Experience and perspectives of patient stakeholders regarding patient-centred care and treatment decisions. Our patient stakeholders represented a diverse socio-demographic group. The patient stakeholders identified engagement and dialogue with physicians as crucial elements of patient-centred care model. The degree of patient-centred care was observed to be dependent on the situations. High severity conditions warranted a higher level of patient involvement, compared to mild conditions. They agreed that patient-centred care should not mean that patients can demand inappropriate treatments. An important attribute of patient-centred outcomes research model is the involvement of stakeholders. However, we have limited knowledge about the experience of patient stakeholders in patient-centred outcomes research. Our study indicates that patient stakeholders offer a unique perspective as researchers and policy-makers aim to precisely define patient-centred research and care.

System of regional centres of first aid in cases of radiation accidents in Germany

1996-01-01

When in the seventies the number of occupational radiation exposed persons in the Federal Republic of Germany increased from about 35,000 (1974) to about 160,000 (1978) the Industrial Injuries Insurance Institutes felt prompted to reflect about special measures to prevent radiation accidents and provide health care for this special cases. They did so without any actual occasion: accidents were persons have been exposed by ionizing radiation were in the seventies just as rare as today. But that fact does not allow the Industrial Injuries Insurance Institutes to neglect the existing potential for severe accidents. So the Industrial Injuries Insurance Institute for the Electrical Industry including Precision Mechanics and the Industrial Injuries Insurance Institute for the Chemical Industry created the Institute for Radiation Protection in 1978. The primary task of that Institute is to guarantee an effective first aid in the case of a radiation accident. To realize that task the Institute contracted 11 wellknown institutions like radiological departments of large hospitals or the medical departments of research centres where the i knowledge on diagnostic and therapy of radiation effects is present. They are called 'Regionale Strahlenschutzzentren', Regional Centres for Radiation Protection (RCRP). In the case of radiation accidents these RCRP are the logistical centres for all arising questions of treatment. They have facilities for reconstructing exposure situations and assessing and evaluating doses, including measurements of internal contamination as well as for medical inpatient or out-patient treating like internal or external decontamination. Another important task of the RCRP is to advise employers in ad radiation protection questions which arise with the industrial application of ionizing radiation. Of course the centres give also answer to many question from members of the public, for example the personal effects of the power plant accident at Chernobyl

Volunteers from Peter MacCallum Cancer Centre (Peter Mac) Patient Information and Support Centre (PISC) assist the Cancer Support Nurse by helping patients and families/carers find information and provide face-to-face peer support. Benefits of shared personal experiences between volunteer and patient are clearly different from professional support. Volunteers require specific skill sets and detailed preparation for this role. Volunteers completed a 3-day training programme adapted from the Cancer Council Victoria's 'Cancer Connect Telephone Peer Support Volunteer' training programme. The focus was role expectations and boundaries for peer support volunteers, debriefing, communication skills training, support services, complementary and alternative therapies and internet information. Assessment included a quiz and observation for a range of competencies. Role-play with simulated patients developed appropriate support skills. Eight volunteers participated. Pre-training questionnaires revealed all volunteers highly self-rated existing skills supporting people affected by cancer. During training, volunteers recognised these skills were inadequate. All agreed that role-play using an actor as a 'simulated patient' helped develop communication skills; however, the experience proved challenging. Post-training all reported increased knowledge of role definition and boundaries, supportive communication skills, supports available for patients and families/carers and importance of self-care. Facilitators recommended seven of the eight participants be accredited PISC Peer Support Volunteers. One volunteer was assessed unsuitable for consistently overstepping the boundaries of the peer support role and withdrew from training. Success of the programme resulted in a trained 'face-to-face peer support volunteer' group better equipped for their role. Sixteen months following training, all who completed the programme remain active volunteers in the PISC. Planned educational updates

Background: This epidemiological observational study aimed at determining the prevalence of malnutrition in non-selected adults with cancer, to identify risk factors of malnutrition and correlate the results with length of stay and 2-month mortality. Methods: This prospective multicentre 1-day study conducted in 17 French Comprehensive Cancer Centres included 1545 patients. Body mass index (BMI), weight loss (WL) in the past 6 months and age were routinely recorded according to the French national recommendations for hospitalised patients; malnutrition was rated as absent, moderate or severe according to the level of WL and BMI. Age, sex, tumour site, type of hospitalisation and treatment, disease stage, World Health Organisation performance status (PS) and antibiotic therapy were the potential malnutrition risk factors tested. Follow-up at 2 months allowed to determine the correlation with length of stay and mortality. Results: Malnutrition was reported in 30.9% of patients, and was rated as severe in 12.2%. In multivariate analysis, only pre-existing obesity (BMI⩾30), PS ⩾2 and head-and-neck or upper digestive cancers were associated with increased risk of malnutrition. Antibiotics use was significantly higher in malnourished patients (35.5 vs 22.8% Pmalnutrition was independently associated with mortality. The median length of stay was 19.3±19.4 days for malnourished patients vs 13.3±19.4 days for others (Pmalnutrition in our cancer patient population perhaps because of a misidentification or a delay in nutrition support in this category of patients.

Full Text Available A 10-year survival of 3482 lung cancer patients residing in Tomsk region was studied. Based on the populationbased cancer registry data, the observed, corrected and relative survival rates were calculated by the actuarial method taking into consideration age, sex, disease stage and place of residence of the patients. Survival rates were lower in males than in females: the difference in the overall observed survival (OS rate was from 5.1 % (8-year OS to 7.3 % (2-year OS. An inverse relationship between survival and cancer spread was observed. Survival rates were higher for urban populations than for rural populations. The analysis indicated that most lung cancer cases were diagnosed at an advanced stage. Survival rates demonstrated relatively equal levels of cancer care in different regions of Russia. When comparing survival rates in Tomsk region with those in Europe and the USA, it was shown that one-year survival was lower in Tomsk region than in Europe and the USA, thus indicating more effective cancer screening programs in European countries and the USA.

Incorporating person centred care principles into an ongoing comprehensive cancer management program: An experiential account

Vallath Nandini

2011-01-01

Full Text Available Recent research indicates a definite positive impact on treatment outcomes when an integrative approach that focuses on symptom control and quality of life is provided along with the standard therapeutic regimens. However implementation or practice of this approach is not seen widely due to the culture of medical training and practice. This article presents the initial development of a program for incorporating integrative care principles into an ongoing comprehensive cancer care program at a tertiary centre. The key purpose of the program being to develop, facilitate, and establish comprehensive and holistic processes including palliative care principles, that would positively enhance the quantity and quality of life of the person with disease, as well as create an environment that reflects and sustains this approach. The vision, objectives, goals, strategies, activities and results within the 7 months of implementation are documented. The new learnings gained during the process have also been noted in the hope that the model described may be used to conceptualize similar care giving facilities in other centres.

Growing evidence of the association between health professionals' well-being and patient and organisational outcomes points to the need for effective staff support. This paper reports a brief survey of the UK's children's cancer Principal Treatment Centres (PTCs) regarding staff support systems and practices. A short on-line questionnaire, administered in 2012-2013, collected information about the availability of staff support interventions which seek to prevent work-related stress among different members of the multi-disciplinary team (MDT). It was completed by a member of staff with, where required, assistance from colleagues. All PTCs (n = 19) participated. Debriefs following a patient death was the most frequently reported staff support practice. Support groups were infrequently mentioned. There was wide variability between PTCs, and between professional groups, regarding the number and type of interventions available. Doctors appear to be least likely to have access to support. A few Centres routinely addressed work-related stress in wider staff management strategies. Two Centres had developed a bespoke intervention. Very few Centres were reported to actively raise awareness of support available from their hospital's Occupational Health department. A minority of PTCs had expert input regarding staff support from clinical psychology/liaison psychiatry. © 2016 The Authors. European Journal of Cancer Care Published by John Wiley & Sons Ltd.

Spatial aspects of planning logistical centres: The case of the economic centre Feniks in the Posavje Region

Directory of Open Access Journals (Sweden)

Jure Zavrtanik

2009-01-01

Full Text Available Spatial planning of logistics centres follows specific spatial and infrastructural requirements, conditioned by desired traffic flux and scope. Spatial and environmental limitations of the usual freight handling sites are forcing logistical activities to search for areas that can ensure undisturbed expansion and practically unlimited traffic flows. The consequence of this trend is suburbanisation coupled with all the spatial and environmental effects. Within this framework, set against the awareness of the uniqueness of any particular site, the article points out the significance of a comprehensive and timely spatial and environmental planning of logistical centres. Therefore clear spatial objectives, transparent analytical starting blocks and adequate planning regulation prove to be the imperative in the spatial planning of logistical centres and formulation of the spatial concept. Simultaneously, and with respect to the complexity of spatial developments, the significance of territorial cohesion is emphasised, which is manifested as territorial identity, territorial quality and territorial efficiency.

Background Schistosomiasis and soil-transmitted helminthiasis (STH) are widely distributed in Cameroon. Although mass drug administration (MDA) of mebendazole is implemented nationwide, treatment with praziquantel was so far limited to the three northern regions and few health districts in the southern part of Cameroon, based on previous mapping conducted 25 years ago. To update the disease distribution map and determine where treatment with praziquantel should be extended, mapping surveys were conducted in three of the seven southern regions of Cameroon, i.e. Centre, East and West. Methodology Parasitological surveys were conducted in April–May 2010 in selected schools in all 63 health districts of the three targeted regions, using appropriate research methodologies, i.e. Kato-Katz and urine filtration. Principal Findings The results showed significant variation of schistosomiasis and STH prevalence between schools, villages, districts and regions. Schistosoma mansoni was the most prevalent schistosome species, with an overall prevalence of 5.53%, followed by S. haematobium (1.72%) and S. guineensis (0.14%). The overall prevalence of schistosomiasis across the three regions was 7.31% (95% CI: 6.86–7.77%). The prevalence for Ascaris lumbricoides was 11.48 (95% CI: 10.93–12.04%), Trichuris trichiura 18.22% (95% CI: 17.56–18.90%) and hookworms 1.55% (95% CI: 1.35–1.78%), with an overall STH prevalence of 24.10% (95% CI: 23.36–24.85%) across the three regions. STH was more prevalent in the East region (46.57%; 95% CI: 44.41–48.75%) in comparison to the Centre (25.12; 95% CI: 24.10–26.17%) and West (10.49%; 95% CI: 9.57–11.51%) regions. Conclusions/Significance In comparison to previous data, the results showed an increase of schistosomiasis transmission in several health districts, whereas there was a significant decline of STH infections. Based on the prevalence data, the continuation of annual or bi-annual MDA for STH is recommended, as well as an

Fuel cycle centres

International Nuclear Information System (INIS)

Hagen, M.

1977-01-01

The concept of co-locating and integrating fuel cycle facilities at one site is discussed. This concept offers considerable advantages, especially in minimizing the amount of radioactive material to be transported on public roads. Safeguards and physical protection as relating to such an integrated system of facilities are analysed in detail, also industrial and commercial questions. An overall risk-benefit evaluation turns out to be in favour of fuel cycle centres. These centres seem to be specifically attractive with regard to the back end of the fuel cycle, including on-site disposal of radioactive wastes. The respective German approach is presented as an example. Special emphasis is given to the site selection procedures in this case. Time scale and cost for the implementation of this concept are important factors to be looked at. Since participation of governmental institutions in these centres seems to be indispensable their respective roles as compared to industry must be clearly defined. The idea of adjusting fuel cycle centres to regional rather than national use might be an attractive option, depending on the specific parameters in the region, though results of existing multinational ventures are inconclusive in this respect. Major difficulties might be expected e.g. because of different national safety regulations and standards as well as commercial conditions among partner countries. Public acceptance in the host country seems to be another stumbling block for the realization of this type of multinational facilities

In Malaysia, prostate cancer is ranked 6th among male cancer and expected to increase in the future. Several factors have shown to be related to prostate cancer such as sociodemographic, lifestyle, diet, occupational exposure, medical and health status. This is the first time a similar study was conducted in Malaysia to recognize the risk factors for prostate cancer patients who came for treatment at University Kebangsaan Malaysia Medical Centre (UKMMC). Prostate cancer cases diagnosed between 2003 and 2008 which met with the inclusion criteria were included in the study. One hundred and twelfth (112) pairs of cases and controls matched by age and ethnicity were analysed. McNemar Odds Ratios (OR(M)) were calculated using McNemar Calculator software for univariate analysis while conditional logistic regression was used for multivariate analysis, both using SPSS version 12.0. Most of the prostate cancer patients (68.8%) that came for treatment in UKMMC were above 70 years old. The majority were Chinese (50.0%) followed by Malay (46.4%) and Indian (3.6%). Multivariate analysis showed cases were more likely to have a first-degree relative with a history of cancer (OR= 3.77, 95% CI= 1.19-11.85), to have been exposed to pesticides (OR= 5.57, 95% CI= 1.75-17.78) and consumed more meat (OR= 12.23, 95% CI= 3.89-39.01). Significantly reduced risks of prostate cancer were noted among those consuming more vegetables (OR= 0.12, 95% CI= 0.02-0.84), more tomatoes (OR= 0.35, 95% CI= 0.13-0.93) and those who had frequent sexual intercourse (OR= 0.44, 95% CI= 0.19-0.96). Some lifestyle and occupation factors are strong predictors of the occurrence of prostate cancer among patients in UKMMC. More importantly, with the identification of the potentially modifiable risk factors, proper public health intervention can be improved.

Regionalization of complex surgeries has increased patient travel distances possibly leaving a substantial burden on those at risk for poorer surgical outcomes. To date, little is known about travel patterns of cancer surgery patients in regionalized settings. To inform this issue, we sought to assess travel patterns of those undergoing a major cancer surgery within a regionalized system. We identified 4733 patients who underwent lung, esophageal, gastric, liver, pancreatic, and colorectal resections from 2002-2014 within a multihospital system in the Mid-Atlantic region of the United States. Patient age, race and/or ethnicity, and insurance status were extracted from electronic health records. We used Geographical Information System capabilities in R software to estimate travel distance and map patient addresses based on cancer surgery type and these characteristics. We used visual inspection, analysis of variance, and interaction analyses to assess the distribution of travel distances between patient populations. A total of 48.2% of patients were non-white, 49.9% were aged >65 y, and 54.9% had private insurance. Increased travel distance was associated with decreasing age and those undergoing pancreatic and esophageal resections. Also, black patients tend to travel shorter distances than other racial and/or ethnic groups. These maps offer a preliminary understanding into variations of geospatial travel patterns among patients receiving major cancer surgery in a Mid-Atlantic regionalized setting. Future research should focus on the impact of regionalization on timely delivery of surgical care and other quality metrics. Copyright © 2015 Elsevier Inc. All rights reserved.

This review was performed to describe the patient pathway and timelines involved in the treatment of FIGO (International Federation of Gynecology and Obstetrics) stage IB1 to IVA cervical cancer in a New Zealand cancer centre. Retrospective audit of women with a new diagnosis of FIGO Stage IB1–IVA cervical cancer in the Auckland/Northland regions between 2003 and 2007. Two hundred and seven patients were identified. Median time from referral to first specialist assessment (FSA) was 10 days, from FSA to decision to treat (DTT) 50 days and from DTT to start of treatment 26 days. Overall median time from referral to start of treatment was 97 days. There was no difference in median time from referral to DTT for patients treated with primary surgery (48 days) or radiotherapy (47 days). On univariate analysis, factors associated with reduced time from referral to start of treatment were less socioeconomic deprivation (P = 0.001), shorter time to completion of radiological investigations (P < 0.0005) and private FSA (P < 0.0005). Only private FSA remained significant on multivariate analysis. The greatest delay in the pathway was between FSA and DTT, encompassing presentation at multidisciplinary meeting, examination under anaesthetic and obtaining radiological investigations. Median overall treatment time (OTT) for patients treated with definitive radiotherapy was 56 days and was increased by a median of 3 days where there were delays accessing operating theatre time for brachytherapy insertions. Overall patient pathway and radiotherapy OTT were longer than optimal, and areas of delay potentially amenable to modification were identified.

The use of bone scintigraphy to establish cancer extension records: application to prostate and breast cancers

The recent development of the technique described, especially in the systematic search for metastases was due to the introduction of stannous diphosphate complexed with sup(99m)Tc well suited to bone scintigraphy. The documents are obtained in two stages. First a whole-body scintigraph is taken by means of an omniview device fitted to a Picker dynacamera, and this scanning phase is followed immediately by static views centred mainly on abnormal or doubtful regions. The results are given for 136 breast cancers and 61 prostate cancers, two cancers particularly liable to affect the bone, and show that scintigraphy offers positive advantages over radiological investigations. These advantages are offset to some extent by the non-specific nature of the hyperfixing regions since different diseases involving changes in the bone structure can give similar images, but for breast and prostate cancers bone scintigraphy presents distinct possibilities in the search for metastases of the skeleton [fr

Life expectancy for people with spinal cord injury has shown a marked increase due to modern advances in treatment methods and in neuro-urology. However, since life expectancy of people with paralysis increases, the risk of developing of urinary bladder cancer is gaining importance. Single-centre retrospective evaluation of patient data with spinal cord injuries and proven urinary bladder cancer and summary of the literature. Between 1998 and 2014, 24 (3 female, 21 male) out of a total of 6599 patients with spinal cord injury were diagnosed with bladder cancer. The average age at bladder cancer diagnosis was 57.67 years, which is well below the average for bladder cancer cases in the general population (male: 73, female: 77). All but one patient had a latency period between the onset of the spinal paralysis and tumour diagnosis of more than 10 years. The median latency was 29.83 years. The median survival for these patients was 11.5 months. Of the 24 patients, 19 (79%) had muscle invasive bladder cancer at ≥T2 at the time of diagnosis. The type of neurogenic bladder (neurogenic detrusor overactivity or acontractility) and the form of bladder drainage do not appear to influence the risk. Long-term indwelling catheter drainage played only a minor role in the investigated patients. The significantly younger age at onset and the frequency of invasive tumours at diagnosis indicate that spinal cord injury influences bladder cancer risk and prognosis as well. Early detection of bladder cancer in patients with spinal cord injury remains a challenge.

Lung cancer continues to be one of the most common cancers in Canada, with approximately 28,400 new cases diagnosed each year. Although timely care can contribute substantially to quality of life for patients, it remains unclear whether it also improves patient outcomes. In this work, we used a set of quality indicators that aim to describe the quality of care in lung cancer patients. We assessed adherence with existing guidelines for timeliness of lung cancer care and concordance with existing standards of treatment, and we examined the association between timeliness of care and lung cancer survival. Patients with lung cancer diagnosed between 2010 and 2015 were identified from the Pulmonary Division Lung Cancer Registry at our centre. We demonstrated that the interdisciplinary pulmonary oncology service successfully treated most of its patients within the recommended wait times. However, there is still work to be done to decrease variation in wait time. Our results demonstrate a significant association between wait time and survival, supporting the need for clinicians to optimize the patient care trajectory. It would be helpful for Canadian clinicians treating patients with lung cancer to have wait time guidelines for all treatment modalities, together with standard definitions for all time intervals. Any reductions in wait times should be balanced against the need for thorough investigation before initiating treatment. We believe that our unique model of care leads to an acceleration of diagnostic steps. Avoiding any delay associated with referral to a medical oncologist for treatment could be an acceptable strategy with respect to reducing wait time.

Most women with breast cancer who undergo breast-conserving surgery receive whole-breast irradiation. We examined whether the addition of regional nodal irradiation to whole-breast irradiation improved outcomes. We randomly assigned women with node-positive or high-risk node-negative breast cancer who were treated with breast-conserving surgery and adjuvant systemic therapy to undergo either whole-breast irradiation plus regional nodal irradiation (including internal mammary, supraclavicular, and axillary lymph nodes) (nodal-irradiation group) or whole-breast irradiation alone (control group). The primary outcome was overall survival. Secondary outcomes were disease-free survival, isolated locoregional disease-free survival, and distant disease-free survival. Between March 2000 and February 2007, a total of 1832 women were assigned to the nodal-irradiation group or the control group (916 women in each group). The median follow-up was 9.5 years. At the 10-year follow-up, there was no significant between-group difference in survival, with a rate of 82.8% in the nodal-irradiation group and 81.8% in the control group (hazard ratio, 0.91; 95% confidence interval [CI], 0.72 to 1.13; P=0.38). The rates of disease-free survival were 82.0% in the nodal-irradiation group and 77.0% in the control group (hazard ratio, 0.76; 95% CI, 0.61 to 0.94; P=0.01). Patients in the nodal-irradiation group had higher rates of grade 2 or greater acute pneumonitis (1.2% vs. 0.2%, P=0.01) and lymphedema (8.4% vs. 4.5%, P=0.001). Among women with node-positive or high-risk node-negative breast cancer, the addition of regional nodal irradiation to whole-breast irradiation did not improve overall survival but reduced the rate of breast-cancer recurrence.

Purpose: Local control rates for breast cancer in genetically predisposed women are poorly defined. Because such a small percentage of breast cancer patients have proven germline mutations, surrogates, such as a family history for breast cancer, have been used to examine this issue. The purpose of this study was to evaluate local-regional control following breast conservation therapy (BCT) in patients with bilateral breast cancer and a breast cancer family history. Methods and Materials: We retrospectively reviewed records of all 58 patients with bilateral breast cancer and a breast cancer family history treated in our institution between 1959 and 1998. The primary surgical treatment was a breast-conserving procedure in 55 of the 116 breast cancer cases and a mastectomy in 61. The median follow-up was 68 months for the BCT patients and 57 months for the mastectomy-treated patients. Results: Eight local-regional recurrences occurred in the 55 cases treated with BCT, resulting in 5- and 10-year actuarial local-regional control rates of 86% and 76%, respectively. In the nine cases that did not receive radiation as a component of their BCT, four developed local-regional recurrences (5- and 10-year local-regional control rates of BCT without radiation: 49% and 49%). The 5- and 10-year actuarial local-regional control rates for the 46 cases treated with BCT and radiation were 94% and 83%, respectively. In these cases, there were two late local recurrences, developing at 8 years and 9 years, respectively. A log rank comparison of radiation versus no radiation actuarial data was significant at p = 0.009. In the cases treated with BCT, a multivariate analysis of radiation use, patient age, degree of family history, margin status, and stage revealed that only the use of radiation was associated with improved local control (Cox regression analysis p = 0.021). The 10-year actuarial rates of local-regional control following mastectomy with and without radiation were 91% and 89

To compare cancer mortality rates in Amazon cantons (counties) with and without long-term oil exploration and extraction activities. Mortality (1990 through 2005) and population census (1990 and 2001) data for cantons in the provinces of the northern Amazon Region (Napo, Orellana, Sucumbios, and Pastaza), as well as the province with the capital city of Quito (Pichincha province) were obtained from the National Statistical Office of Ecuador, Instituto Nacional del Estadistica y Censos (INEC). Age- and sex-adjusted mortality rate ratios (RR) and 95% confidence intervals (CI) were estimated to evaluate total and cause-specific mortality in the study regions. Among Amazon cantons with long-term oil extraction, activities there was no evidence of increased rates of death from all causes (RR = 0.98; 95% CI = 0.95-1.01) or from overall cancer (RR = 0.82; 95% CI = 0.73-0.92), and relative risk estimates were also lower for most individual site-specific cancer deaths. Mortality rates in the Amazon provinces overall were significantly lower than those observed in Pichincha for all causes (RR = 0.82; 95% CI = 0.81-0.83), overall cancer (RR = 0.46; 95% CI = 0.43-0.49), and for all site-specific cancers. In regions with incomplete cancer registration, mortality data are one of the few sources of information for epidemiologic assessments. However, epidemiologic assessments in this region of Ecuador are limited by underreporting, exposure and disease misclassification, and study design limitations. Recognizing these limitations, our analyses of national mortality data of the Amazon Region in Ecuador does not provide evidence for an excess cancer risk in regions of the Amazon with long-term oil production. These findings were not consistent or supportive of earlier studies in this region that suggested increased cancer risks.

This review summarizes the rationale for the creation of breast centres and discusses the studies conducted in Germany to obtain proof of principle for a voluntary, external benchmarking programme and proof of concept for third-party dual certification of breast centres and their mandatory quality management systems to the German Cancer Society (DKG) and German Society of Senology (DGS) Requirements of Breast Centres and ISO 9001 or similar. In addition, we report the most recent data on benchmarking and certification of breast centres in Germany. Review and summary of pertinent publications. Literature searches to identify additional relevant studies. Updates from the DKG/DGS programmes. Improvements in surrogate parameters as represented by structural and process quality indicators suggest that outcome quality is improving. The voluntary benchmarking programme has gained wide acceptance among DKG/DGS-certified breast centres. This is evidenced by early results from one of the largest studies in multidisciplinary cancer services research, initiated by the DKG and DGS to implement certified breast centres. The goal of establishing a nationwide network of certified breast centres in Germany can be considered largely achieved. Nonetheless the network still needs to be improved, and there is potential for optimization along the chain of care from mammography screening, interventional diagnosis and treatment through to follow-up. Specialization, guideline-concordant procedures as well as certification and recertification of breast centres remain essential to achieve further improvements in quality of breast cancer care and to stabilize and enhance the nationwide provision of high-quality breast cancer care.

Formaldehyde 6-cm absorption in the direction of the Galactic Centre has been surveyed using the Jodrell Bank MK II radio telescope (beam-width 10 x 9 arcmin). The observations sample the region - 2 0 = 0 and - 0 0 .5 = 0 .5, with a velocity range of 620 km s -1 , a velocity resolution of 2.1 km s -1 and an rms noise level of approximately 0.03 K. The data are presented as contour maps showing line temperature as a function of latitude and velocity (b-V maps) and as a function of longitude and velocity (l-V maps). Similar maps of the line-to-continuum ratio are also presented. The radial distribution of formaldehyde (H 2 CO) in the Galactic Centre region is derived using two different kinematic models which give similar results. Formaldehyde is strongly concentrated in the Galactic Centre in a layer of latitude extent approximately 0 0 .5 and longitude extent approximately 4 0 which contains one quarter of all the H 2 CO in the Galaxy. The distribution is centred on l approximately 1 0 . The individual H 2 CO features are described in detail. (author)

Ambient air samples were collected, from 2006 to 2008 at three rural and two urban sites in Centre Region (France) and analyzed for 56 currently used pesticides (CUPs), of which 41 were detected. The four CUPs most frequently detected were the herbicides trifluralin, acetochlor and pendimethalin and the fungicide chlorothalonil, which were found with frequencies ranging between 52 and 78%, and with average concentrations of 1.93, 1.32, 1.84 and 12.15 ng m -3, respectively. Among the detected pesticides, concentrations of eight fungicides (spiroxamine, fenpropimorph, cyprodinil, tolyfluanid, epoxiconazole, vinchlozolin, fluazinam, fludioxinil), two insecticides (propargite, ethoprophos), and one herbicide (oxyfluorfen) are, to our knowledge, reported for the first time in the literature. The majority of the CUPs showed a seasonal trend, with most of the detections and the highest concentrations occurring during the spring and early summer. The most important pesticides detected were related to arable crops and fruit orchards, the main cultures in this region, highlighting the fact that the main sources come from local applications. Minor differences were found in the profiles of pesticides within rural areas and between rural and urban areas.

Full Text Available The success of radiotherapy cancer treatment delivery depends on the accuracy of patient setup for each fraction. A significant problem arises from reproducing the same patient position and prostate location during treatment planning for every fraction of the treatment process. To analyze the daily movements of the prostate, gold markers are implanted in the prostate and portal images taken and manually matched with reference images to locate the prostate. Geometrical and fiducial markers are annotated onto a highly quality generated digitally reconstructed radiographs, that are compared with portal images acquired right before treatment dose delivery. A 0 and 270 degree treatment fields are used to calculate prostate shifts for all prostate cancer patients undergoing treatment at the Sweden Ghana Medical Centre, using an iViewGT portal imaging device. After aligning of the marker positions onto the reference images, the set-up deviations corrections are displayed and an on-line correction procedure applied. The measured migrations of the prostate markers are below the threshold of 3 mm for the main plans and 2 mm for the boost plans. With daily electronic portal imaging combined with gold markers, provides an objective method for verifying and correcting the position of the prostate immediately prior to radiation delivery.--------------------------------------------Cite this article as: Acquah GF.

Opioid consumption before and after the establishment of a palliative medicine unit (PMU) in an Egyptian cancer centre was reviewed. A comparison of consumption during the year before the PMU was established to consumption during the third year after the PMU's establishment revealed that morphine consumption increased by 698 percent, fentanyl by 217 percent, and tramadol by 230 percent. Expressed in defined daily dose (DDD) and adjusted for 1,000 new cancer patients, consumption increased by 460 percent, from 4,678 DDD/1,000 new patients to 26,175 DDD/1,000 new patients. Expressed in grams of oral morphine equivalent (g OME), consumption increased by 644 percent, from 233 g OME/1,000 new patients to 1,731 g OME/1,000 new patients. The establishment of the PMU was associated with an increase in opioid consumption, especially morphine, which is an indicator of improvement in cancer pain control. The expression of opioid consumption in OME in addition to DDD may provide further information, especially when weak opioids are included in the analysis.

Full Text Available Abstract Background Chemo-radiotherapy offers an alternative to primary surgery and adjuvant therapy for the management of locally advanced stage IV squamous cell carcinomas of the tonsil. Methods A retrospective analysis was performed of the outcomes of 41 patients with locoregionally advanced squamous cell carcinoma of the tonsil treated non-surgically at the Yorkshire Cancer Centre between January 2004 and December 2005. Due to long radiotherapy waiting times, patients received induction chemotherapy with cisplatin and 5-fluorouracil followed by either cisplatin concurrent chemoradiotherapy or radiotherapy alone. Results Median age was 55 years (range 34-76 years and 28 (68% patients were male. 35/41 patients (85% received 2 or more cycles of induction chemotherapy. Following induction chemotherapy, 32/41 patients (78% had a clinical response. Concomitant chemotherapy was given to 30/41 (73%. All patients received the planned radiotherapy dose with no delays. There were no treatment related deaths. Six (15% patients had gastrostomy tubes placed before treatment, and 22 (54% required nasogastric tube placement during or after treatment for nutritional support. 17 patients required unplanned admissions during treatment for supportive care. At 4 months post treatment assessment 35 out of 41 (85% patients achieved complete clinical and radiographic response. Median follow-up is 38 months (8-61 months. Local and regional control rate in complete responders at 3 years was 91%. Distant metastases have been found in 4 (9.8% patients. Three year progression-free survival rate in all patients is 75%. The 3-year cause specific survival and overall survival are 75% and 66% respectively. Conclusion Cisplatin-based induction and concurrent chemoradiotherapy provides excellent tumour control with acceptable toxicity for patients with locally advanced tonsillar cancer.

There is an increasing use of 3-D conformal radiotherapy (3DCRT) in the radiotherapeutic management of prostate cancer. The Faculty of Radiation Oncology Genito-Urinary Group carried out a survey of Australian and New Zealand radiotherapy centres in the preparation of a consensus workshop. Of the 19 centres that were represented, there were 24 radiation oncologists, 16 radiation therapists and 12 medical physicists. The survey collected demographic information and data on the practices undertaken at those centres when delivering curative radiotherapy in the treatment of prostate cancer. There was much variation in the delivery of treatment in the areas of patient set-up, contouring of target volumes and organs of interest during computer planning, the techniques and the dose constraints used in these techniques, the use of adjuvant androgen deprivation therapy and the quality assurance processes used in monitoring effects of treatment. This variability reflects the range of data in the published literature. Emerging trends of practices were also identified. This is a first report on a multi-disciplinary approach to the development of guidelines in 3DCRT of prostate cancer. Copyright (2004) Blackwell Science Pty Ltd

Full Text Available BACKGROUND & OBJECTIVES: Cervical cancer is the most common preventable cancer noted in Indian women , having a major impact on their lives. Approximately , 70% of people reside in villages in India. Hence, the objectives of this study were to find the knowledge of women regarding cervical cancer, to determine attitude and practices towards screening. METHODS : A cross - sectional study was conducted in Primary Health Centre , Periapodu, Tamil Nadu, India between January 2015 and May 2015 where 1670 participants between the ages of 21 - 65 years were randomly chosen by selecting every 3 rd woman attending the PHC for any reason. After exclusion, 1200 participants were included in the study. RESULTS : Mean age of the study population was 45.3 years. An awa reness of 75.42% was noted for cervical cancer, 43.25% for Human Papillomavirus and 32.42% that it was vaccine preventable, the major source of information being Healthcare Providers (70%. Despite 50.58% thinking that they were at risk of cervical cancer, only 31% had undergone a pap smear. However, 69.96% of the unscreened population were ready to undergo screening. Independent predictors for doing Pap test included age >35, higher parity, literacy and adequate knowledge of cervical cancer screening ( P <0. 05. CONCLUSION: This study shows a low level of knowledge, attitude and practice on cervical cancer among women in rural India. Increasing women’s awareness would be a first step in the long chain of conditions to attain a lower incidence and mortality

International Nuclear Information System (INIS)

Osei, R. K.

2012-01-01

The effective dose and cancer risk were determined for patients undergoing seven different types of CT examinations in two CT facilities in the Greater Accra region of Ghana. The two facilities, namely; the Diagnostic Centre Ltd and Cocoa Clinic were chosen because of their significant patient throughput. The effective dose was from patient data namely age, sex, height, weight and technique factors; namely scan length, KVp (Kilovolts peak), mAs (milliamperes per second) and CTDIv from the control console of the CT machines. The effective dose was also estimated using the dose length product (DLP) and k Coefficients which is the anatomic region specific conversion factors. The cancer risk for each patient for a particular examination was determined from the effective dose, age and sex of each patient with the help of BEIR VII. In all, a total number of 800 adult patients with 400 from each of the two CT facilities were compiled. From Diagnostic Centre Ltd, the average effective dose was 5.61mSv in the range of 1.41mSv to 13.34mSv with average BMI of 26.19kg/m 2 in the range of 16.90kg/m 2 to 48.28kg/m 2 for all types of examinations. The average cancer risk was 0.0458 Sv - 1 for 400 patients in the range of 0.0001 Sv - 1 to 0.3036 Sv -1 compared with a population of 900 patients undergoing CT examination per year. From Cocoa Clinic, the average effective dose was 3.91MSv in the range of 0.54mSv to 27.32mSv with an average BMI of 25.59 kg/m 2 in the range of 17.18kg/m 2 to 35.34kg/m 2 and the average cancer risk was 0.0371 Sv - 1 in the range of 0.0001 Sv - 1 and 0.7125 Sv -1 . Some of the values were within the range of values of typical for typical effective dose for CT examinations reported by the ICRP. It was evident from this study that the variations in scanning parameters had significant impact on the effective doses to patient for similar CT examinations among the two facilities.(au)

Objective: To provide an overview of the incidence and mortality of female breast cancer for countries in the Asia-Paciifc region. Methods: Statistical information about breast cancer was obtained from publicly available cancer registry and mortality databases (such as GLOBOCAN), and supplemented with data requested from individual cancer registries. Rates were directly age-standardised to the Segi World Standard population and trends were analysed using joinpoint models. Results: Breast cancer was the most common type of cancer among females in the region, accounting for 18% of all cases in 2012, and was the fourth most common cause of cancer-related deaths (9%). Although incidence rates remain much higher in New Zealand and Australia, rapid rises in recent years were observed in several Asian countries. Large increases in breast cancer mortality rates also occurred in many areas, particularly Malaysia and hTailand, in contrast to stabilising trends in Hong Kong and Singapore, while decreases have been recorded in Australia and New Zealand. Mortality trends tended to be more favourable for women aged under 50 compared to those who were 50 years or older. Conclusion: It is anticipated that incidence rates of breast cancer in developing countries throughout the Asia-Pacific region will continue to increase. Early detection and access to optimal treatment are the keys to reducing breast cancer-related mortality, but cultural and economic obstacles persist. Consequently, the challenge is to customise breast cancer control initiatives to the particular needs of each country to ensure the best possible outcomes.

Control options for communal energy turnaround by energy coordination centres. Investigation based on the Erzgebirge energy region; Steuerungsmoeglichkeiten der kommunalen Energiewende durch Energieleitstellen. Untersuchung anhand der Energieregion-Erzgebirge

Energy Technology Data Exchange (ETDEWEB)

Zuk, David

2012-11-01

The book investigates the role of energy coordination centres for communal energy turnaround. The investigations were carried out in the Erzgebirge energy region, which comprises 13 member communities. It was found that the influence of an energy coordination centre on a community is parallel to the community's awareness of the necessity of local energy turnaround measures. Energy control centres can sharpen this awareness of communities by outlining individual advantages of engagement with these issues and by making concrete suggestions for projects. Here, it becomes clear that communities will be more interested especially in bigger investment projects of an (external)financially strong investor. Most of the communities under investigation were in the range of 1,000 to 7,000 inhabitants; it must be assumed that in this case the opinions of the highest-ranked person of communal authority. This consideration should influence the scope of action of energy coordination centres. The example of a 'pioneering community' in the energy region showed that the consulting services of the energy coordination centre not only led to lower energy consumption (and, in consequence, lower energy expenses) on a medium-term basis but also helped to coordinate the activities of initiatives, e.g. initiatives promoting citizens-owned solar power stations. As the book shows, energy coordination centres take care of communities in general but are also actively supporting initiatives within the community and have a coordinating function when it comes to intercommunity projects. While energy coordination centres are not a 'heal-all' for implementation of the energy turnaround at community level or regional level, they must be viewed as a powerful instrument to achieve it.

There is growing interest in the use of more aggressive therapeutic modalities for treating metastatic prostate cancer. In this study, we examine the use of stereotactic body radiation therapy (SBRT) for patients with oligorecurrent prostate cancer. We analysed the biochemical response and toxicity of patients who underwent this therapy at our centre. We selected patients who experienced oligorecurrence between January 2015 to December 2016 and were administered SBRT. The association of androgen deprivation (AD) was left in each case to the decision of the tumour committee. We describe the clinical situation at diagnosis of oligorecurrence, the treatment administered and the biochemical response. We considered a biochemical response to be a 50% reduction in the absolute prostate-specific antigen (PSA) readings. SBRT was administered to 11 patients with bone (82%) and/or lymph node oligometastasis (18%). The treatment regimen for bone oligometastasis was 27Gy divided into 3 sessions, while the treatment for lymph node oligometastasis reached 70Gy. Seven patients had no treatment at the time of diagnosis, 2 were in the castration-resistant phase, 1 patient was in the off phase of intermittent AD, and 1 patient had adjuvant AD for pN1. Seven patients presented a biochemical response with a PSA reduction of 75-100%. The response was not assessable in 4 patients due to the continuing adjuvant AD. With a mean follow-up of 10.5 months, only 2 patients had progressed. Grade 1 gastrointestinal toxicity was detected in only 1 patient. Our data suggest that the use of SBRT in carefully selected patients with metastatic oligorecurrence of prostate cancer can achieve biochemical response and potentially delay progression and the use of systemic treatments.

Contact radiotherapy for early rectal cancer uses 50 kV X-rays to treat rectal cancers under direct vision. We present data of a series of patients treated at a single centre with prospective follow-up and functional assessment. All patients were treated at the Queen's Centre for Oncology, Hull, UK between September 2011 and October 2015. Patients received a biopsy, magnetic resonance imaging (MRI) of the liver/pelvis, computed tomography of the chest and endorectal ultrasound. Patients were deemed to be either unfit for radical surgery or refused it due to the need for a permanent stoma. Follow-up consisted of 3 monthly flexible sigmoidoscopy and MRI of the liver/pelvis and 12 monthly computed tomography of the chest. In total, 42 patients were treated with contact radiotherapy ± external beam chemo/radiotherapy without any primary surgical excision. The median age was 78 years (range 50-94 years). Local recurrence-free survival was 88%, disease-free survival was 86% and overall survival was 88% with a median follow-up of 24 months (range 5-54 months). The median time to recurrence was 12 months (range 4-14 months). The estimated 30 day surgical mortality for this cohort with radical surgery was 12%. Mortality from the contact radiotherapy procedure was 0%. Functional outcomes as investigated by the Low Anterior Resection Syndrome (LARS) score were good, with 65% having no LARS. Contact radiotherapy for early rectal cancer is a safe, well-tolerated outpatient procedure, allowing organ preservation, with excellent oncological and functional outcomes. For elderly co-morbid patients with suitable rectal cancers this should be considered as a standard of care. Crown Copyright © 2016. Published by Elsevier Ltd. All rights reserved.

Lymphedema is a prevalent long-term effect of breast cancer treatment that is associated with reduced quality of life. More recent observational data suggest that the addition of night-time compression to day-time use of a compression garment results in better long-term control of arm lymphedema. The primary objectives of the randomized controlled phase of the trial are to determine the efficacy of night-time compression on arm lymphedema volume maintenance and quality of life in breast cancer survivors who have completed intensive reduction treatment for their lymphedema. The study will be a parallel 3-arm, multi-centre randomized fast-track trial. A total of 120 women with breast cancer related lymphedema will be recruited from 3 centres in Canada and randomized to group 1: Day-time compression garment alone or Group 2: Day-time compression garment + night-time compression bandaging or Group 3: Day-time compression garment + use of a night-time compression system garment. The duration of the primary intervention period will be 12 weeks. The follow-up period after the intervention (weeks 13 to 24) will follow a longitudinal observational design. The primary outcome variables: differences from baseline to week 12 in arm volume and quality of life (Lymphoedema Functioning, Disability and Health Questionnaire: Lymph-ICF). Secondary outcomes include bioimpedance analysis, sleep disturbance and self-efficacy. All measurements are standardized and will be performed prior to randomization, and at weeks 6, 12, 18 and 24. The use of night-time compression as a self-management strategy for chronic breast cancer related lymphedema is seen as an innovative approach to improve long-term control over the condition. This trial aims to advance the knowledge on self-management strategies for lymphedema

Accessibility to essential cancer medications in low- and middle-income countries is threatened by insufficient availability and affordability. The objective of this study is to characterize variation in transactional prices for essential cancer medications across geographies, medication type, and time. Drug purchase prices for 19 national and international buyers (representing 29 total countries) between 2010 and 2014 were obtained from Management Sciences for Health. Median values for drug pricing were computed, to address outliers in the data. For comparing purchase prices across geographic units, medications, and over time; Mann-Whitney U tests were used to compare two groups, Kruskal Wallis H tests were used to compare more than two groups, and linear regression was used to compare across continuous independent variables. During the five-year data period examined, the median price paid for a package of essential cancer medication was $12.63. No significant differences in prices were found based on country-level wealth, country-level disease burden, drug formulation, or year when medication was purchased. Statistical tests found significant differences in prices paid across countries, regions, individual medications, and medication categories. Specifically, countries in the Africa region appeared to pay more for a package of essential cancer medication than countries in the Latin America region, and cancer medications tended to be more expensive than anti-infective medications and cardiovascular medications. Though preliminary, our study found evidence of variation in prices paid by health systems to acquire essential cancer medications. Primarily, variations in pricing based on geographic location and cancer medication type (including when comparing to essential medicines that treat cardiovascular and infectious diseases) indicate that these factors may impact availability, affordability and access to essential cancer drugs. These factors should be taken into

Colorectal cancer is a heterogeneous group of malignancies with complex molecular subtypes. While colon cancer has been widely investigated, studies on rectal cancer are very limited. Here, we performed multi-region whole-exome sequencing and single-cell whole-genome sequencing to examine the genomic intratumor heterogeneity (ITH) of rectal tumors. We sequenced nine tumor regions and 88 single cells from two rectal cancer patients with tumors of the same molecular classification and characterized their mutation profiles and somatic copy number alterations (SCNAs) at the multi-region and the single-cell levels. A variable extent of genomic heterogeneity was observed between the two patients, and the degree of ITH increased when analyzed on the single-cell level. We found that major SCNAs were early events in cancer development and inherited steadily. Single-cell sequencing revealed mutations and SCNAs which were hidden in bulk sequencing. In summary, we studied the ITH of rectal cancer at regional and single-cell resolution and demonstrated that variable heterogeneity existed in two patients. The mutational scenarios and SCNA profiles of two patients with treatment naïve from the same molecular subtype are quite different. Our results suggest each tumor possesses its own architecture, which may result in different diagnosis, prognosis, and drug responses. Remarkable ITH exists in the two patients we have studied, providing a preliminary impression of ITH in rectal cancer.

Prior to 1976, the Radiation Medicine Centre had conducted 12 short courses of five weeks' duration on medical uses of radioisotopes. A total of 162 medical and scientific personnel attended the courses from various parts of India. Owing to the rapid advances made in nuclear medicine these courses were becoming inadequate, and in 1973 the Centre introduced one-year full time training courses for doctors and science graduates, peparing them for examinations for the Diploma in Radiation Medicine (DRM) and the Diploma in Medical Radioisotope Techniques (DMRIT) of the University of Bombay. By March 1984, 64 doctors and 53 technologists had obtained the DRM and DMRIT. A recent survey indicated that 70% of the DRM physicians and 68% of the DMRIT technologists are employed in nuclear medicine departments. Besides the formal one-year training courses, the Centre has conducted advanced courses of two weeks' duration on scintigraphy and thyroid function tests. The Radiation Medicine Centre has been the regional reference centre in nuclear medicine for the World Health Organization and International Atomic Energy Agency for more than ten years. The Centre has trained sponsored personnel from other countries of the region. The Centre has also organized seven symposia, workshops and seminars, four of them in collaboration with WHO and one with the IAEA. (author)

1985-01-01

Three cases of radiation-induced cancer in the oral regions were reported with relation to radiation therapy. One was the general radiation-induced cancer following radiotherapy for the hemangioma. The other two cases, which belonged in the B-1 group of Sakai and his coworker's diagnostic criteria for radiation-induced cancer, were those occurring after radiotherapy for the malignant tumors. Due to the relatively high dosage exposure by the patient in the radiotherapy it is necessary to look out the latency of the radiation-induced cancer. After radiotherapy, careful and periodical observation is important for immediate treatment in an early stage for the radiation-induced cancer to have a favorable prognosis. In addition careful observation of the changes after radiotherapy helps in discovering the precancerous lesions from the therapy. For the radiation-induced cancer, surgical treatment would be the best, however, radiation therapy is also effective in certain cases. (author)

Full Text Available OBJECTIVE: Patient chances for cure and palliation for a variety of malignancies may be greatly affected by the care provided by a treating hospital. We sought to determine the effect of volume and teaching status on patient outcomes for five gynecologic malignancies: endometrial, cervical, ovarian and vulvar carcinoma and uterine sarcoma. METHODS: The Florida Cancer Data System dataset was queried for all patients undergoing treatment for gynecologic cancers from 1990-2000. RESULTS: Overall, 48,981 patients with gynecologic malignancies were identified. Endometrial tumors were the most common, representing 43.2% of the entire cohort, followed by ovarian cancer (30.9%, cervical cancer (20.8%, vulvar cancer (4.6%, and uterine sarcoma (0.5%. By univariate analysis, although patients treated at high volume centers (HVC were significantly younger, they benefited from an improved short-term (30-day and/or 90-day survival for cervical, ovarian and endometrial cancers. Multivariate analysis (MVA, however, failed to demonstrate significant survival benefit for gynecologic cancer patients treated at teaching facilities (TF or HVC. Significant prognostic factors at presentation by MVA were age over 65 (HR = 2.6, p<0.01, African-American race (HR = 1.36, p<0.01, and advanced stage (regional HR = 2.08, p<0.01; advanced HR = 3.82, p<0.01, respectively. Surgery and use of chemotherapy were each significantly associated with improved survival. CONCLUSION: No difference in patient survival was observed for any gynecologic malignancy based upon treating hospital teaching or volume status. Although instances of improved outcomes may occur, overall further regionalization would not appear to significantly improve patient survival.

We used a very large dataset (>40% of all species) from the endemic-rich Cape Floristic Region (CFR) to explore the impact of different weighting techniques, coefficients to calculate similarity among the cells, and clustering approaches on biogeographical regionalisation. The results were used to revise the biogeographical subdivision of the CFR. We show that weighted data (down-weighting widespread species), similarity calculated using Kulczinsky’s second measure, and clustering using UPGMA resulted in the optimal classification. This maximized the number of endemic species, the number of centres recognized, and operational geographic units assigned to centres of endemism (CoEs). We developed a dendrogram branch order cut-off (BOC) method to locate the optimal cut-off points on the dendrogram to define candidate clusters. Kulczinsky’s second measure dendrograms were combined using consensus, identifying areas of conflict which could be due to biotic element overlap or transitional areas. Post-clustering GIS manipulation substantially enhanced the endemic composition and geographic size of candidate CoEs. Although there was broad spatial congruence with previous phytogeographic studies, our techniques allowed for the recovery of additional phytogeographic detail not previously described for the CFR.

To estimate and analyze the evolution of mortality rates of gastrointestinal (GI) cancer in Peru and its regions between 2005-2014. We performed a nationwide secondary analysis of Peru's Health Ministry registry of deaths during the period 2005-2014, with a focus on regional differences. Deaths registered with codes C15 to C25 (malignant neoplasms of digestive organs) from the ICD-10 were included. Calculation of age-standarized mortality rates and years of life lost (YLL) due to GI cancer per 100,000 habitants were also performed. Data of 67,527 deaths from GI cancers was analyzed, 35,055 (51.91%) were women. In 2005, the number of GI cancer deaths was 6,484, for 2014, 7,532 cases were recorded. The GI cancer age-standarized mortality rates at the country level showed a decrease of 12.70% between 2005-2014. Stomach cancer presented the highest age-standarized mortality rate despite showing a downward trend in the last years, equal for gallbladder, liver and biliary tract, and esophagus cancer. Colorectal, small intestine and anus cancer show a progressive increase. In 2014, Callao (48.8), Huancavelica (48.5), La Libertad (39.6), Lambayeque (40.5) and Huanuco (38.9) had the highest rates. The three types of GI cancers with the highest rates of YLL in 2014 were stomach cancer (118.51), followed by liver and biliary tract cancer (58.68) and colorectal (44.86). GI cancer mortality in Peru is high and a priority issue in regions like Huancavelica, Huanuco, Callao, La Libertad and Lambayeque. Stomach cancer remains the most frequent GI cancer, but with a downward trend in the study period.

Cancer outcomes for people living in rural and remote areas are worse than for those living in urban areas. Although access to and quality of cancer treatment are important determinants of outcomes, delayed presentation has been observed in rural patients. Formative research with people from rural Western Australia (WA) led to the Find Cancer Early campaign. Find Cancer Early was delivered in three regions of WA, with two other regions acting as controls. Staff delivered the campaign using a community engagement approach, including promotion in local media. Television communications were not used to minimize contamination in the control regions. The campaign evaluation was undertaken at 20 months via a computer-assisted telephone interview (CATI) survey comparing campaign and control regions. The primary outcome variable was knowledge of cancer signs and symptoms. Recognition and recall of Find Cancer Early and symptom knowledge were higher in the campaign regions. More than a quarter of those who were aware of the campaign reported seeing the GP as a result of their exposure. Despite limited use of mass media, Find Cancer Early successfully improved knowledge of cancer symptoms and possibly led to changes in behavior. Social marketing campaigns using community development can raise awareness and knowledge of a health issue in the absence of television advertising.

1964-01-01

Since 1958 the General Conferences of the International Atomic Energy Agency have discussed the establishment of scientific centres which would help the Agency to carry out its statutory functions. Subsequently, decisions were taken which have led to the foundation of two laboratories and the establishment under the Agency's auspices of an isotope centre. The plans for the setting up of the Agency's Laboratory Vienna - Seibersdorf were approved by the Board of Governors of the International Atomic Energy Agency in April 1 959, and the agreement on the Marine Biological Project at Monaco came into force in March 1961. In March 1963 the Middle Eastern Regional Radioisotope Centre for the Arab countries was opened. The first comprehensive report on the activities of the laboratories and the isotope centre is now published; it contains information on the development of the centres and their activities carried out in 1963. The Agency expresses its gratitude to the Governments of Austria, Monaco and the United Arab Republic for the generous assistance offered in connection with the establishment of the laboratories and the isotope centre

Population-based studies on childhood cancer survival are key to monitor progress against cancer and to detect potential differences between regions and other subgroups in the population. We investigated time trends and factors associated with childhood cancer survival on a national level in Switzerland, from 1976 to 2013. We extracted data from the population-based Swiss Childhood Cancer Registry of 5,776 children (age 0-14 years) diagnosed with cancer from 1985 to 2014 in Switzerland. We calculated age-adjusted 5-year survival, defined the annual reduction in risk of death (ARR), and explored associations of survival with clinical and demographic factors. Overall, 5-year survival improved significantly, from 64% in 1976-1983 to 88% in 2004-2013. ARR over the whole period was 4% for all diagnostic groups, greatest for Hodgkin lymphomas (8%), ependymomas (6%), Burkitt's lymphomas (6%) and germ cell tumours (6%). Children treated in hospitals without specialised paediatric cancer centre for leukaemia (HR 12.9), lymphoma (HR 5.0) and neuroblastoma (HR 3.7) were at higher risk of death. In French-speaking Switzerland, risk of death was lower for lymphoma (HR 0.6), CNS tumours (HR 0.7) and neuroblastoma (HR 0.5). Children with migration background had a higher risk of death from all tumours except bone tumours. Childhood cancer survival significantly improved from 1976 to 2013, but there is room for further improvement. Survival rates varied by type of clinical treatment, language region and nationality. All paediatric cancer patients should be referred to a specialised paediatric cancer centre. Further research is needed to intervene and completely eliminate inequalities in survival. © 2016 UICC.

Full Text Available Rationale: Analysis of the cancer incidence and mortality in the population is of major importance for planning of measures aimed at improvement of organization of medical care to cancer patients, ensuring high quality and availability of this type of medical care.Aim: To evaluate cancer-related incidence and mortality rates and structure among the population of the Moscow Region depending on patient gender and tumor localization.Materials and methods: The estimation and analysis of incidence and mortality rates was performed based on the Reporting Form of the Federal Statistic Surveillance #7 “Information on disorders related to malignant tumors” in the Moscow Region in 2014. For mortality analysis, including that among pediatric patients, we used data from the State Statistics Service of the Moscow Region.Results: In 2014, there were 25 600 new cases of malignancies diagnosed in the Moscow Region, that corresponded to the incidence rate of 363.2 per 100,000 of the population. The leading types of newly diagnosed tumors in men were prostate cancer, as well as tracheal, bronchial and lung cancers (54.2 and 47.0 per 100,000 of male population, respectively. In women, the highest incidence rates were found for breast and skin cancers (86.0 and 58.9 per 100,000 of female population, respectively. According to the data from Rosstat, in 2014, the overall cancer mortality rate in the Moscow Region was 228.1 per 100,000 of the population. Among the causes of cancer mortality in men, the leading one was tracheal, bronchial and lung cancer (22.2%, followed by stomach cancer (13.3% and prostate cancer (8.1%. In women, the leading cause of cancer mortality was breast cancer (16.6%, followed by ovarian, uterine and cervical cancers (14.1% and stomach cancer (11.4%.Conclusion: Based on the results of medical and statistical analysis of cancer incidence and mortality rates, the main direction of improvement of medical care to cancer patients and the ways

MicroRNA-148a (miR-148a was reported to have low expression in gastrointestinal cancers, and might be regulated by promoter region DNA methylation. Methods: Bisulfite-modified sequencing was used to determine the promoter region DNA methylation status of human gastrointestinal cancer cell lines. Expression levels of miR-148a in cell lines treated with 5-aza-2′-deoxycytidine were determined by quantitative real-time polymerase chain reaction. Total DNA was extracted from the tissues of 64 patients with gastric cancer and 51 patients with colorectal cancer. Methylation status was determined by methylation-specific polymerase chain reaction. All statistical analyses were performed with SPSS 17.0 software. Results: The promoter regions of genes in human gastrointestinal cancer cell lines were all hypermethylated, except for HT-29, and the expression of miR-148a tended to be higher than in controls after treatment with 5-aza-2′-deoxycytidine. The methylation-specific polymerase chain reaction results showed that 56.25% of gastric cancer tissues and 19.61% of colorectal cancer tissues were hypermethylated. A strong correlation was found between the expression of miR-148a and the methylation status of promoter regions (P<0.001, chi-square test and Pearson’s correlation. Furthermore, promoter region CpG site hypermethylation of miR-148a was correlated with increased tumor size (P=0.01 in gastric cancer after analyzing the correlation between

Squamous cell vulvar cancers (SCVC) are rare. Although management guidelines have recently been published, New Zealand studies presenting "real world" outcomes are limited. Retrospective single-centre review of SCVC diagnosed between 1 January 2000 and 31 August 2015. Clinical characteristics and outcomes were reviewed. Among 47 cases reviewed, 38 were ethnically European and 9 Māori. Cases identified as Stage 1 (16), Stage 2 (5), Stage 3 (17), Stage 4 (9). For Stages 1, 2, 3 and 4, (16, 4, 17 and 6) were managed by local excision; (9, 1, 14 and 2) by node dissection and (2, 1, 3 and 5) by chemoradiotherapy respectively. Wound cellulitis (10) and lymphedema (8) were the commonest acute and late complication, respectively. Seven patients were treated with 5-Fluorouracil and Mitomycin, and four received weekly Cisplatin. Grade 3 toxicities seen in five cases treated with 5-Fluorouracil and Mitomycin versus none in the Cisplatin group. No local recurrences observed in patients treated with chemoradiation. Patients with Age Adjusted Charlson Comorbid Index Score (ACCIS) <5 had better overall survival (OS) compared to scores ≥5 (60% versus 41%) with 33 months median follow-up. Five-year OS and disease-free specific survival was 73% and 94% (Stage 1), 40% and 60% (Stage 2), 44% and 59% (Stage 3) and 29% (Stage 4) respectively. We present "real world" outcomes of vulvar cancers in this older and comorbid population. Larger, prospective multi-centre studies are proposed.

The Pacific Regional Cancer Coalition (PRCC) provides regional leadership in the U.S. Affiliated Pacific Islands (USAPI) to implement the Regional Comprehensive Control Plan: 2007-2012, and to evaluate its coalition and partnerships. The Pacific Center of Excellence in the Elimination of Disparities (CEED), aims to reduce cancer disparities and conducts evaluation activities relevant to cancer prevention and control in the USAPI. The PRCC Self (internal) and Partner (external) Assessments were conducted to assess coalition functioning, regional and national partnerships, sustainability, and the role of regionalism for integrating all chronic disease prevention and control in the Pacific. Self-administered questionnaires and key informant telephone interviews with PRCC members (N=20), and representatives from regional and national partner organizations were administered (N=26). Validated multi item measures using 5-point scales on coalition and partnership characteristics were used. Chronbach's alphas and averages for the measures were computed. Internal coalition measures: satisfaction (4.2, SD=0.48) communication (4.0, SD=0.56), respect (4.0, SD=0.60) were rated more highly than external partnership measures: resource sharing (3.5, SD=0.74), regionalism (3.9, SD=0.47), use of findings (3.9, SD=0.50). The PRCC specifically identified its level of "collaboration" with external partners including Pacific CEED. External partners identified its partnership with the PRCC in the "coalition" stage. PRCC members and external partners are satisfied with their partnerships. All groups should continue to focus on building collaboration with partners to reflect a truly regional approach to sustain the commitment, the coalitions and the programming to reduce cancer in the USAPI. PRCC and partners should also work together to integrate all chronic disease prevention and control efforts in the Pacific.

Due to the complexity of diagnosis and treatment, care for children and young adolescents with cancer preferably occurs in specialised paediatric oncology centres with potentially better cure rates and minimal late effects. This study assessed where children with cancer in the Netherlands were treated since 2004. All patients aged under 18 diagnosed with cancer between 2004 and 2013 were selected from the Netherlands Cancer Registry (NCR) and linked with the Dutch Childhood Oncology Group (DCOG) database. Associations between patient and tumour characteristics and site of care were tested statistically with logistic regression analyses. This population-based study of 6021 children diagnosed with cancer showed that 82% of them were treated in a paediatric oncology centre. Ninety-four percent of the patients under 10 years of age, 85% of the patients aged 10-14 and 48% of the patients aged 15-17 were treated in a paediatric oncology centre. All International Classification of Childhood Cancers (ICCC), 3rd edition, ICCC-3 categories, except embryonal tumours, were associated with a higher risk of treatment outside a paediatric oncology centre compared to leukaemia. Multivariable analyses by ICCC-3 category revealed that specific tumour types such as chronic myelogenous leukaemia (CML), embryonal carcinomas, bone tumours other type than osteosarcoma, non-rhabdomyosarcomas, thyroid carcinomas, melanomas and skin carcinomas as well as lower-staged tumours were associated with treatment outside a paediatric oncology centre. The site of childhood cancer care in the Netherlands depends on the age of the cancer patient, type of tumour and stage at diagnosis. Collaboration between paediatric oncology centre(s), other academic units is needed to ensure most up-to-date paediatric cancer care for childhood cancer patients at the short and long term.

Cancer survival varies by place of residence, but it remains uncertain whether this reflects differences in tumour, patient and treatment characteristics (including tumour stage, indicators of socioeconomic status (SES), comorbidity and information on received surgery and radiotherapy) or possibly regional differences in the quality of delivered health care. National population-based data from the Cancer Registry of Norway were used to identify cancer patients diagnosed in 2002-2011 (n = 258,675). We investigated survival from any type of cancer (all cancer sites combined), as well as for the six most common cancers. The effect of adjusting for prognostic factors on regional variations in cancer survival was examined by calculating the mean deviation, defined by the mean absolute deviation of the relative excess risks across health services regions. For prostate cancer, the mean deviation across regions was 1.78 when adjusting for age and sex only, but decreased to 1.27 after further adjustment for tumour stage. For breast cancer, the corresponding mean deviations were 1.34 and 1.27. Additional adjustment for other prognostic factors did not materially change the regional variation in any of the other sites. Adjustment for tumour stage explained most of the regional variations in prostate cancer survival, but had little impact for other sites. Unexplained regional variations after adjusting for tumour stage, SES indicators, comorbidity and type of treatment in Norway may be related to regional inequalities in the quality of cancer care. © 2015 UICC.

Background Population-based epidemiologic studies about colorectal cancer are lacking in China. This study aims to provide a basis for colorectal cancer screening and prevention, through analysis and comparisons the characteristics of the trends in colorectal cancer incidence in Beijing and selected representative regions. RESULTS The annual incidence rate in Beijing region increased significantly, from 9.40/100,000 in 1998 to 18.61/100,000 in 2012. The stratified rate showed that the incidence of distal colon adenocarcinoma increased substantially in men, especially in those aged > 75 years and residing in urban areas. Although the incidence rate in Beijing is still lower than in Shanghai, Jiashan, and Hong Kong in China, it is increasing rapidly. Further, the incidence rate in Beijing is lower than in New York, Oxford and Osaka, but higher than in Mumbai and Kyadondo. The incidence trend in Beijing is increasing especially in older groups, while in other regions such as New York, it is decreasing in these age groups. Materials and Methods Colorectal cancer incidence data were obtained from Beijing Cancer Registry and Cancer Incidence in Five Continents Plus database. All incidence rates were age-standardized according to Segi's world population. Incidence trends were characterized by calculating the annual percent changes using the Joinpoint Regression Program. Conclusions Compared with other regions, Beijing has a medium level of colorectal cancer incidence, however, it is increasing significantly. There are obvious differences in the cancer subsite, sex and age distributions between Beijing and other regions. Prevention and screening of colorectal cancer in Beijing should be strengthened.

Secondary and multiple primary cancers relating radiation therapy for squamous cell carcinoma (s.c.c.) of the oral region including lip, oral cavity and oropharynx were analyzed. Out of 1,197 patients with s.c.c. treated with radiation during about 30 years from 1955 to 1983 June, 56 patients (4.7 %) were regarded as double or multiple cancer. The multiple cancer (s.c.c.) was observed frequently in the multicentric zone such as hypopharynx, esophagus and bronchus as well as in other sites of the oral cavity; 67.7 % (42 out of 62 sites). Frequency of synchronous double cancers was increased in recent ten years; 47.1 % (16/34). Careful examination to the above mentioned multicentric zone leads to early detection of secondary cancer and could be expected cure of the disease. Although possibility of radiation-induced cancer could not be ruled out as for 17 patients with late recurrence (more than 8 years), different histologic diagnosis from s.c.c. was obtained in only one (malignant fibrous histiocytoma). Therefore, it was difficult to discriminate radiation-induced cancer from late recurrence in the present study. (author)

Purpose: To study pulmonary radiological abnormalities with computer tomography (CT) following different radiotherapy (RT) techniques for breast cancer with respect to regions and density, and their correlation to pulmonary complications and reduction in vital capacity (VC). Methods and Materials: CT scans of the lungs were performed prior to and 4 months following RT in 105 breast cancer patients treated with local or local-regional RT. The radiological abnormalities were analyzed with a CT-adapted modification of a classification system originally proposed by Arriagada, and scored according to increasing density (0-3) and affected lung regions (apical-lateral, central-parahilar, basal-lateral). The highest density grade in each region were added together to form scores ranging from 0-9. The patients were monitored for RT-induced pulmonary complications. VC was measured prior to and 5 months following RT. Results: Increasing CT scores were correlated with both local-regional RT and pulmonary complications (p < 0.001). The mean reduction of VC for patients scoring 4-9 (-202 ml) was larger than for patients scoring 0-3 (-2 ml) (p = 0.035). The effect of confounding factors on the radiological scoring was tested in the local-regional RT group. Scores of 4-9 were less frequently seen in the patients who had received adjuvant chemotherapy prior to RT. The importance of the respective lung regions on the outcome of pulmonary complications was tested. Only radiological abnormalities in the central-parahilar and apical-lateral regions were significantly correlated to pulmonary complications. Discussion: Radiological abnormalities detected on CT images and scored with a modification of Arriagada's classification system can be used as an objective endpoint for pulmonary side effects in breast cancer. The described model should, however, be expanded with information about the volume of lung affected in each region before definite conclusions can be drawn concerning each

The optimal time of rectal resection after long-course chemoradiotherapy (CRT) remains unclear. A feasibility study was undertaken for a multi-centre randomized controlled trial evaluating the impact of the interval after chemoradiotherapy on the technical complexity of surgery. Patients with rectal cancer were randomized to either a 6- or 12-week interval between CRT and surgery between June 2012 and May 2014 (ISRCTN registration number: 88843062). For blinded technical complexity assessment, the Observational Clinical Human Reliability Analysis technique was used to quantify technical errors enacted within video recordings of operations. Other measured outcomes included resection completeness, specimen quality, radiological down-staging, tumour cell density down-staging and surgeon-reported technical complexity. Thirty-one patients were enrolled: 15 were randomized to 6 and 16-12 weeks across 7 centres. Fewer eligible patients were identified than had been predicted. Of 23 patients who underwent resection, mean 12.3 errors were observed per case at 6 weeks vs. 10.7 at 12 weeks (p = 0.401). Other measured outcomes were similar between groups. The feasibility of measurement of operative performance of rectal cancer surgery as an endpoint was confirmed in this exploratory study. Recruitment of sufficient numbers of patients represented a challenge, and a proportion of patients did not proceed to resection surgery. These results suggest that interval after CRT may not substantially impact upon surgical technical performance.

Full Text Available Abstract Background Evidence for the association between Human immunodeficiency virus infection and cervical cancer has been contrasting, with some studies reporting increased risk of cervical cancer among HIV positive women while others report no association. Similar evidence from Tanzania is scarce as HIV seroprevalence among cervical cancer patients has not been rigorously evaluated. The purpose of this study was to determine the association between HIV and tumor differentiation among patients with cervical cancer at Bugando Medical Centre and Teaching Hospital in Mwanza, North-Western Tanzania. Methods This was a descriptive analytical study involving suspected cervical cancer patients seen at the gynaecology outpatient clinic and in the gynaecological ward from November 2010 to March 2011. Results A total of 91 suspected cervical cancer patients were seen during the study period and 74 patients were histologically confirmed with cervical cancer. The mean age of those confirmed of cervical cancer was 50.5 ± 12.5 years. Most patients (39 of the total 74–52.7% were in early disease stages (stages IA-IIA. HIV infection was diagnosed in 22 (29.7% patients. On average, HIV positive women with early cervical cancer disease had significantly more CD4+ cells than those with advanced disease (385.8 ± 170.4 95% CI 354.8-516.7 and 266.2 ± 87.5, 95% CI 213.3-319.0 respectively p = 0.042. In a binary logistic regression model, factors associated with HIV seropositivity were ever use of hormonal contraception (OR 5.79 95% CI 1.99-16.83 p = 0.001, aged over 50 years (OR 0.09 95% CI 0.02-0.36 p = 0.001, previous history of STI (OR 3.43 95% CI 1.10-10.80 p = 0.035 and multiple sexual partners OR 5.56 95% CI 1.18-26.25 p = 0.030. Of these factors, only ever use of hormonal contraception was associated with tumor cell differentiation (OR 0.16 95% CI 0.06-0.49 p = 0.001. HIV seropositivity was weakly associated with

This publication describes the environmental changes and the influencing factors occurring within the administrative regions of the Uusimaa Regional Environment Centre. The quality of the environment can be judged as satisfying in regards to both the mental and physical health of humans. Areas have a steady trend of a relatively high growth in population density, while the efficiency of land use in new settlements is low. Traffic and the travel distances are on the rise. A considerable part of the population lives in areas where the noise standards are violated, despite control measures. Waste management, water distribution and sewage networks are under continuous development. In regards to the nature, the situation in some parts is of great concern. The manifold of the nature, cultural landscapes and culturally valuable buildings and sites are threatened. The living space of flora and fauna is continuing to decrease and change. The risks caused by human activities in groundwater areas are increasing. For these reasons the implementation of protection programs is important. Emissions from point sources to the water and air have significantly decreased. Yet, the impacts of air quality deprivation can still be seen in some cities and in the vicinity of some industrial sites. The eutrophication have essentially changed the ecology and fishstocks; however, the water quality has improved in many places. Regarding the above issues, as well as some other topics, included in the report are 16 theme maps 66 pictures. However, the report states that the monitoring and reporting of the environmental quality should be improved. (orig.)

A nomogram for prediction of 12-year sarcoma-specific survival has been developed based on patients with soft tissue sarcomas treated in Memorial Sloan Kettering Cancer Centre (MSKCC). We aim to evaluate the predictive accuracy of the MSKCC sarcoma nomogram in a cohort of patients treated at an Asian institution. This has not been validated in an Asian population and thus its universal applicability remains unproven. Between 1990 and 2013, 840 adult patients underwent treatment for primary soft tissue sarcoma (STS) at the National Cancer Centre Singapore. Patients who presented with locally recurrent or metastatic disease were excluded from the analysis. The variables included in the MSKCC nomogram included age at diagnosis, tumor size, histologic grade, histologic subtype, depth and site. A total of 399 patients were left for analysis. The nomogram was validated by assessing its extent of discrimination and level of calibration. All patients had deep tumors. Disease occurred most commonly in the lower extremity (n = 149 [37.3%]), the most common histologic subtype was "Others" (angiosarcoma, ewing's sarcoma, endometrial stromal sarcoma, sarcoma NOS [not otherwise specified] and rhabdomyosarcoma). Sixty-four percent of all patients had high-grade tumors while 36% had low-grade tumors. The median patient age at diagnosis was 54 years (range: 17-88 years). The median follow up time for all patients and surviving patients were 29 (range: 1-174) and 33 (range: 1-157) months, respectively. The observed 5- and 10-year sarcoma-specific survival were 55% and 33%, respectively. The concordance index was 0.71. For level of calibration, the observed correspondence between predicted and actual outcomes suggest that the MSKCC nomogram generally predicts well for patients with higher survival probability, but consistently overpredicts survival for the other groups, in our cohort of patients. The MSKCC sarcoma nomogram was found to be accurate in terms of extent of discrimination

Purpose. To examine the relationship between esophageal and gastric cancers commonly seen in Van Lake region and the traditional eating habits of the geography. Materials and Methods. Esophageal and gastric cancer cases, who underwent surgery between January 1, 2012, and December 31, 2013, were examined. Pathology reports of the patients and presence of Helicobacter pylori (HP) were recorded. Surveys were filled by face to face meeting or telephone call. Control group was created with randomly selected individuals without any cancer diagnosis having age, gender, and socioeconomic characteristics similar to patient group. All data were analyzed using SAS.9.3 statistical programme. Results. Compared with the control group, herby cheese consumption (a component of eating habits) and smoking were significantly higher in the patient group (P gender, and significant difference was found between the groups (P = 0.0013). As a result of the analysis with logistic regression more than 150 gr of herby cheese consumption per day was found to increase the cancer risk (odds ratio 1.017; 95% CI: 1.012-1.022). Conclusion. A high consumption of herby cheese, cooking bread on tandoor, and heavy smoking were seen to be important risk factors for esophageal and gastric cancers.

The ratios of basal cell carcinomas (BBC) to squamous cell carcinomas (SCC) and to malignant melanomas (MM) have changed over time in the white population throughout the world. To evaluate the incidence of skin cancers in the Mosan region and the Belgian Ardennes over the past 6 years. In contrast with epidemiological data reported by the Belgian National Cancer Registry, cutaneous cancers are the commonest malignancies occurring in humans. At the present time, the ratio BCC:SCC roughly equals 4 to 1. When combined, the incidence of BCC and SCC is about 10 times greater than that of MM. The rate of detection of skin cancers does not always correlate with the rate of notification of a national registry.

There have been few reports of sarcoid reaction in the regional lymph nodes associated with lung cancer. The purpose of this study was to analyze the surgical results of lung cancer with sarcoid reaction. Of 1733 lung cancer patients undergoing surgical treatment in our institute from 1990 to 2004, we reviewed 22 patients (1.3%) with sarcoid reaction in the regional lymph nodes of lung cancer. On pre-operative computed tomography (CT), mediastinal lymph node swelling was detected in 19 patients (86%) as clinical N3 disease (c-N3) in six or as c-N2 in 13, while three patients were classified as c-N0. To these 19 patients, lymph node status was histologically checked by mediastinoscopy in four patients, sternotomy approach in two and open mini-thoracotomy in 13. Because the sampling-biopsy nodes showed no tumor metastasis, radical surgery was promptly performed. However, four patients (18%) were finally judged to have pathological lymph node positive disease. Five patients were in pathological stage (p-stage) IA, nine in p-stage IB, five in p-stage IIB, two in p-stage IIIA, and one in stage IIIB. The overall 3-, and 5-year survival rates of these patients were 85.2 and 77.7%, respectively, with no significant difference compared to those of the remaining patients without sarcoid reaction. Because lung cancer patients with sarcoid reaction in the regional lymph nodes frequently show mediastinal lymph node swelling on CT, radical resection should be performed after confirming the node status by appropriate sampling biopsy. It seems that surgical results of lung cancers with sarcoid reaction in the regional nodes are not prognostically different from those without sarcoid reaction. (author)

A method of carrying out region-wide audit for breast cancer was developed by collaboration between the cancer registry, providers and purchasers as part of work to fulfill the 'Calman-Hine' recommendations. In order to test the audit method, a retrospective audit in North Thames East compared practice in 1992 against current guidelines. The analysis compared care in specialist and non-specialist centres. A stratified random sample comprising 28% of all breast cancer patients diagnosed in 1992 was selected from the population-based Thames Cancer Registry. The data for 309 patients with stage I-III tumours were analysed by hospital type using local guidelines. No difference between specialist (high volume) and non-specialist centres was detected for factors important in survival. Pathological staging was good with over 70% reporting tumour size and grade. A small number of patients were undertreated; after conservative surgery, 10% (19) of women did not receive radiotherapy, and 15% (8) of node-positive premenopausal women did not receive chemotherapy or ovarian ablation. In contrast, a significant trend with hospital volume was found for several quality of life factors. These included access to a specialist breast surgeon and specialist breast nurses, availability of fine-needle aspiration (FNA), which ranged from 84% in high-volume to 42% in low-volume centres, and quality of surgery (axillary clearance rates ranged from 51% to 8% and sampling of less than three nodes from 3% to 25% for high- and very low-volume centres respectively). Confidential feedback of results to surgeons was welcomed and initiated change. The summary information gave purchasers information relevant to the evaluation of cancer services. While the audit applied present standards to past practice, it provided the impetus for prospective audit of current practice (now being implemented in North Thames).

The current cancer landscape within transitional economies in central and Eastern Europe and the Mediterranean area is not particularly optimistic. Current perceptions are often based on extrapolations from other countries and regions; and hence the authors collaborated with the South Eastern Europe Oncology Group (SEEROG) to collect information on cancer registration in Central and Eastern Europe, Israel and Turkey. Healthcare authorities and specialist oncology centres in 21 countries in the region were contacted for information on cancer registries in their countries. Based on this information, the authors believe that the recording and reporting of data on cancer in the region is at an acceptable level. The authors discuss and compare institution- and population-based registries, and present opinions on elements of an 'ideal registry' based on the survey replies and comparisons with other registries. A comparison with the sources used for GLOBOCAN 2008 illustrates the need for consistent data to be communicated, published and utilised throughout the region and the oncology community. The authors conclude by considering the potential value of collaboration between health authorities across the region, as well as between the clinical and epidemiological communities, to ensure that cancer data are consistently collected, verified and made public. © 2013 John Wiley & Sons Ltd.

To evaluate the consumption of added fats and oils across the European centres and countries participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). 24-Hour dietary recalls were collected by means of standardised computer-guided interviews in 27 redefined EPIC centres across 10 European countries. From an initial number of 36 900 subjects, single dietary recalls from 22 924 women and 13 031 men in the age range of 35-74 years were included. Mean daily intake of added fats and oils varied between 16.2 g (Varese, Italy) and 41.1 g (Malmö, Sweden) in women and between 24.7 g (Ragusa, Italy) and 66.0 g (Potsdam, Germany) in men. Total mean lipid intake by consumption of added fats and oils, including those used for sauce preparation, ranged between 18.3 (Norway) and 37.2 g day-1 (Greece) in women and 28.4 (Heidelberg, Germany) and 51.2 g day-1 (Greece) in men. The Mediterranean EPIC centres with high olive oil consumption combined with low animal fat intake contrasted with the central and northern European centres where fewer vegetable oils, more animal fats and a high proportion of margarine were consumed. The consumption of added fats and oils of animal origin was highest in the German EPIC centres, followed by the French. The contribution of added fats and oils to total energy intake ranged from 8% in Norway to 22% in Greece. The results demonstrate a high variation in dietary intake of added fats and oils in EPIC, providing a good opportunity to elucidate the role of dietary fats in cancer aetiology.

Elective radiotherapy of the regional lymph node areas in breast cancer

International Nuclear Information System (INIS)

Poortmans, P.M.P.

2006-01-01

In breast cancer patients, the incidence of involvement of the regional lymph nodes and the risk for developing a locoregional recurrence are highly influenced by several prognostic factors. A meta-analysis of the EBCTCG showed a reduction of about 70% of the locoregional recurrence rate with radiotherapy for all patients, independent of age, characteristics of the tumour or the administration of systemic treatment. At the same time, this meta-analysis confirmed that radiotherapy can lead to an increased risk for developing contralateral breast cancer and to an increase in the risk of non-breast cancer related mortality, mainly due to cardiac and pulmonary toxicity. Because of this, the net effect of regional radiotherapy will be strongly influenced by the individual risk factors of the patients and by the quality of the technical aspects of the radiotherapy. The thin line between the benefits of elective regional lymph node irradiation and the possible late toxicity for patients with early stage breast cancer is currently the subject of several prospective randomized trials, the results of which will only become available in several years. Moreover, recent developments in the field of novel prognostic factors will open completely new ways to be explored, which might give bus new tools for estimating the individual benefit/risk ratio for every single patient.

We analyzed 62 cases of thyroid cancer in children and adolescents of Bryansk and Kaluga regions, the most contaminated as a result of the Chernobyl accident. The data on specified radiation situation as well as probable radiation doses to the thyroid are given. It is noted that the development of thyroid cancer depends on the age of children at the time of accident (0-3, 7-9, 12-15 years). They are the most critical periods for the formation and functioning of the thyroid, in particular, in girls. It is suggested that thyroid cancer develops in children and teenagers residing in areas with higher Cs 137 contamination level at younger age than in those residing in less contaminated regions. It is shown that the minimal latent period in the development of thyroid cancer makes up to 5 years. The results of ESR method on tooth enamel specimen indicate that over post-accident period the sufficient share of children has collected such individual radiation dose which are able to affect on their health state and development of thyroid pathology

The challenges facing the European Union Centres of Excellence

On 19 April 2012, the United Nation Security Council congratulated the European Union for its initiative on centres of excellence in the nuclear, radiological, biological, and chemical fields. The time for glowing reports is over. Three years after its creation, the support of EU Member Sates, the Security Council, the G8, the IEAE, the WHO, the USA, Interpol, the ICRC, has been obtained. Other diplomatic, organisational, and communicative challenges have now arisen regarding implementation. The manifest challenges include: 1/Political exploitation of the centres. Following a recent round table in Algiers, the Algerian press ran headlines such as 'terrorism, the Malian crisis arrives in Algiers' CBRN centres of excellence' and 'Bouteflika, the centres of excellence slight'. 2/Communication errors. A unanimously approved expert in South East Asia became a persona non grata over the last six months despite not making any fundamental mistake, aside from his inability to evaluate the degree of a country's sensitivity and pride. The countries in the region went so far as to threaten to pull out of the Manila centre as a result of this ultimately minor error in communication. 3/The scope of the centres' role complicates the grasp of its objectives. To date, the focus has essentially been on non-proliferation and the fight against CBRN terrorism, under the well-established theme of Resolution 1540. The shift of CBRN focus, at the behest of certain regions, on to real natural risks (pandemics) or industrial risks (protection of crucial infrastructure following an earthquake, flooding, or a tsunami) fundamentally changes the teams' make-up and the mobilization of resources. The emergency services culture is different to that of nonproliferation. However, they both very much address CBRN risks and threats. 4/The limits of the 'bottom-up' approach. To date, the centres' success has been due to the lack of restrictive rules. The policy is to enlist willing third-party States

Regional Delivery of Chimeric Antigen Receptor (CAR) T-Cells for Cancer Therapy.

2017-07-18

Chimeric Antigen Receptor (CAR) T-cells are T-cells with recombinant receptors targeted to tumor antigens. CAR-T cell therapy has emerged as a mode of immunotherapy and is now being extensively explored in hematologic cancer. In contrast, CAR-T cell use in solid tumors has been hampered by multiple obstacles. Several approaches have been taken to circumvent these obstacles, including the regional delivery of CAR-T cells. Regional CAR-T cell delivery can theoretically compensate for poor T-cell trafficking and tumor antigen specificity while avoiding systemic toxicity associated with intravenous delivery. We reviewed completed clinical trials for the treatment of glioblastoma and metastatic colorectal cancer and examined the data in these studies for safety, efficacy, and potential advantages that regional delivery may confer over systemic delivery. Our appraisal of the available literature revealed that regional delivery of CAR-T cells in both glioblastoma and hepatic colorectal metastases was generally well tolerated and efficacious in select instances. We propose that the regional delivery of CAR-T cells is an area of potential growth in the solid tumor immunotherapy, and look towards future clinical trials in head and neck cancer, mesothelioma, and peritoneal carcinomatosis as the use of this technique expands.

CAR-T cell therapy has emerged as a mode of immunotherapy and is now being extensively explored in hematologic cancer. In contrast, CAR-T cell use in solid tumors has been hampered by multiple obstacles. Several approaches have been taken to circumvent these obstacles, including the regional delivery of CAR-T cells. Regional CAR-T cell delivery can theoretically compensate for poor T-cell trafficking and tumor antigen specificity while avoiding systemic toxicity associated with intravenous delivery. We reviewed completed clinical trials for the treatment of glioblastoma and metastatic colorectal cancer and examined the data in these studies for safety, efficacy, and potential advantages that regional delivery may confer over systemic delivery. Our appraisal of the available literature revealed that regional delivery of CAR-T cells in both glioblastoma and hepatic colorectal metastases was generally well tolerated and efficacious in select instances. We propose that the regional delivery of CAR-T cells is an area of potential growth in the solid tumor immunotherapy, and look towards future clinical trials in head and neck cancer, mesothelioma, and peritoneal carcinomatosis as the use of this technique expands.

Departing from the widespread use of the internet in modern society and the emerging use of web applications in healthcare this project captures persons' needs and expectations in order to develop highly usable web recourses. The purpose of this paper is to outline a multi-case research project focused on the development and evaluation of person-centred web-based support for people with long-term illness. To support the underlying idea to move beyond the illness, we approach the development of web support from the perspective of the emergent area of person-centred care. The project aims to contribute to the ongoing development of web-based supports in health care and to the emerging field of person-centred care. The research design uses a meta-analytical approach through its focus on synthesizing experiences from four Swedish regional and national cases of design and use of web-based support in long-term illness. The cases include children (bladder dysfunction and urogenital malformation), young adults (living close to persons with mental illness), and two different cases of adults (women with breast cancer and childbearing women with type 1 diabetes). All of the cases are ongoing, though in different stages of design, implementation, and analysis. This, we argue, will lead to a synthesis of results on a meta-level not yet described. To allow valid comparisons between the four cases we explore and problematize them in relation to four main aspects: 1) The use of people's experiences and needs; 2) The role of use of theories in the design of person-centred web-based supports; 3) The evaluation of the effects of health outcomes for the informants involved and 4) The development of a generic person-centred model for learning and social support for people with long-term illness and their significant others. Person-centred web-based support is a new area and few studies focus on how web-based interventions can contribute to the development of person-centred care. In

Full Text Available Abstract. Objectives The aim of the study is to develop a methodology for networking between small towns and regional centres on the basis of developing areas of mutual benefit. It is important to assess the possibility of cooperation between small towns and regional centres and local selfgovernment bodies on the example of individual territorial entities of Russia in the context of the formation and strengthening of networks and support for territorial development. Methods Systemic and functional methodical approaches were taken. The modelling of socio-economic processes provides a visual representation of the direction of positive changes for small towns and regional centres of selected Subjects of the Russian Federation. Results Specific examples of cooperation between small towns and district centres are revealed in some areas; these include education, trade and public catering, tourist and recreational activities. The supporting role of subsystems, including management, regulatory activity, transport and logistics, is described. Schemes, by to which mutually beneficial network interaction is formed, are characterised in terms of the specific advantages accruing to each network subject. Economic benefits of realising interaction between small cities and regional centres are discussed. The methodology is based on assessing the access of cities to commutation, on which basis contemporary regional and city networks are formed. Conclusion On the basis of the conducted study, a list of areas for mutually beneficial networking between small towns and district centres has been identified, allowing the appropriate changes in regional economic policies to be effected in terms of programmes aimed at the development of regions and small towns, including those suffering from economic depression.

To examine the relationship between esophageal and gastric cancers commonly seen in Van Lake region and the traditional eating habits of the geography. Materials and Methods. Esophageal and gastric cancer cases, who underwent surgery between January 1, 2012, and December 31, 2013, were examined. Pathology reports of the patients and presence of Helicobacter pylori (HP) were recorded. Surveys were filled by face to face meeting or telephone call. Control group was created with randomly selected individuals without any cancer diagnosis having age, gender, and socioeconomic characteristics similar to patient group. All data were analyzed using SAS.9.3 statistical programme. Results. Compared with the control group, herby cheese consumption (a component of eating habits) and smoking were significantly higher in the patient group (P<0.001). Tandoor exposure is compared in terms of female gender, and significant difference was found between the groups (P=0.0013). As a result of the analysis with logistic regression more than 150 gr of herby cheese consumption per day was found to increase the cancer risk (odds ratio 1.017; 95% CI: 1.012-1.022). Conclusion. A high consumption of herby cheese, cooking bread on tandoor, and heavy smoking were seen to be important risk factors for esophageal and gastric cancers.

Purpose/Objective: In a former study (1), the hypoxia gene expression classifier, developed in head and neck squamous cell carcinomas, was applied in 89 patients with loco-regional gastroesophageal cancer (GC). Analysis of the 15 genes was indicative of hypoxia being more profound in esophagus...... and display greater heterogeneity compared to AC. However, previous indications that the hypoxia classifier might hold prognostic significance in ESCC patients could not be confirmed. Ongoing work includes in vitro studies of esophageal cancer cell lines in order to identify alternative hypoxia induced genes...... and to further explore the prognostic value of hypoxia in patients with loco-regional gastroesophageal cancer.

Globally, there have been important changes in trends amongst gender, histology and smoking patterns of lung cancer cases. This retrospective study was conducted on 466 patients with lung cancer who were registered in Regional Cancer Center, Regional Institute of Medical Sciences, Manipur from January 2008 to December 2012. Most were more than 60 years of age (67.8%) with a male: female ratio of 1.09:1. Some 78.8% of patients were chronic smokers with male smoker to female smoker ratio of 1.43:1. Consumption of alcohol was found in 29.4%, both smoking and alcohol in 27.5%, betel nut chewing in 37.9% and tobacco chewing in 25.3%. A history of tuberculosis was present in 16.3% of patients. The most frequent symptom was coughing (36.6%) and most common radiological presentation was a mass lesion (70%). Most of the patients had primary lung cancer in the right lung (60.3%). The most common histological subtype was squamous cell carcinoma (49.1%), also in the 40-60 year age group (45.9%), more than 60 year age group (51.6%), males (58.1%) and females (41.8%). As many as 91.9% of squamous cell carcinoma patients had a history of smoking. About 32.5% of patients had distant metastasis at presentation with brain (23.8%) and positive malignant cells in pleural effusions (23.1%) as common sites. The majority of patients were in stage III (34.4%), stage IV (32.5%) and stage II (30.2%). Our analysis suggests that the gender gap has been narrowed such that about half of the patients diagnosed with lung cancer are women in this part of India. This alarming rise in female incidence is mainly attributed to an increased smoking pattern. Squamous cell carcinoma still remains the commonest histological subtype. Most of the patients were elderly aged and presented at locally or distantly advanced stages.

Introduction : One of the most feared complications of childhood cancer treatment is second malignant neoplasms (SMNs). This study evaluates the incidence, risk factors and outcomes of SMNs in a tertiary paediatric oncology centre in Singapore. Materials and Methods : A retrospective review was conducted on patients diagnosed with childhood cancer under age 21 and treated at the National University Hospital, Singapore, from January 1990 to 15 April 2012. Case records of patients with SMNs were reviewed. Results : We identified 1124 cases of childhood cancers with a median follow-up of 3.49 (0 to 24.06) years. The most common primary malignancies were leukaemia (47.1%), central nervous system tumours (11.7%) and lymphoma (9.8%). Fifteen cases developed SMNs, most commonly acute myeloid leukaemia/myelodysplastic syndrome (n = 7). Median interval between the first and second malignancy was 3.41 (0.24 to 18.30) years. Overall 20-year cumulative incidence of SMNs was 5.3% (95% CI, 0.2% to 10.4%). The 15-year cumulative incidence of SMNs following acute lymphoblastic leukaemia was 4.4% (95% CI, 0% to 8.9%), significantly lower than the risk after osteosarcoma of 14.2% (95% CI, 0.7% to 27.7%) within 5 years ( P <0.0005). Overall 5-year survival for SMNs was lower than that of primary malignancies. Conclusion : This study identified factors explaining the epidemiology of SMNs described, and found topoisomerase II inhibitor use to be a likely risk factor in our cohort. Modifications have already been made to our existing therapeutic protocols in osteosarcoma treatment. We also recognised the importance of other risk management strategies, including regular long-term surveillance and early intervention for detected SMNs, to improve outcomes of high risk patients.

Large-scale fuel cycle centres

The US Nuclear Regulatory Commission (NRC) has considered the nuclear energy centre concept for fuel cycle plants in the Nuclear Energy Centre Site Survey 1975 (NECSS-75) Rep. No. NUREG-0001, an important study mandated by the US Congress in the Energy Reorganization Act of 1974 which created the NRC. For this study, the NRC defined fuel cycle centres as consisting of fuel reprocessing and mixed-oxide fuel fabrication plants, and optional high-level waste and transuranic waste management facilities. A range of fuel cycle centre sizes corresponded to the fuel throughput of power plants with a total capacity of 50,000-300,000MW(e). The types of fuel cycle facilities located at the fuel cycle centre permit the assessment of the role of fuel cycle centres in enhancing the safeguard of strategic special nuclear materials - plutonium and mixed oxides. Siting fuel cycle centres presents a smaller problem than siting reactors. A single reprocessing plant of the scale projected for use in the USA (1500-2000t/a) can reprocess fuel from reactors producing 50,000-65,000MW(e). Only two or three fuel cycle centres of the upper limit size considered in the NECSS-75 would be required in the USA by the year 2000. The NECSS-75 fuel cycle centre evaluation showed that large-scale fuel cycle centres present no real technical siting difficulties from a radiological effluent and safety standpoint. Some construction economies may be achievable with fuel cycle centres, which offer opportunities to improve waste-management systems. Combined centres consisting of reactors and fuel reprocessing and mixed-oxide fuel fabrication plants were also studied in the NECSS. Such centres can eliminate shipment not only of Pu but also mixed-oxide fuel. Increased fuel cycle costs result from implementation of combined centres unless the fuel reprocessing plants are commercial-sized. Development of Pu-burning reactors could reduce any economic penalties of combined centres. The need for effective fissile

Lung cancer is the leading cause of cancer-related deaths worldwide. Non-small cell lung cancer (NSCLC) represents the most frequently diagnosed subtype of this morbid malignancy. NSCLC is causally linked to tobacco consumption with more than 500 million smokers worldwide at high risk for this fatal malignancy. We are currently lagging in our knowledge of the early molecular (e.g., genomic) effects of smoking in NSCLC pathogenesis that would constitute ideal markers for early detection. This limitation is further amplified when considering the variable etiologic factors in NSCLC pathogenesis among different regions around the globe. In this review, we present our current knowledge of genomic alterations arising during early stages of smoking-induced lung cancer initiation and progression, including discussing the premalignant airway field of injury induced by smoking. The review also underscores the wider spectra and higher age-adjusted rates of tobacco (e.g., water-pipe smoke) consumption, along with elevated environmental carcinogenic exposures and relatively poorer socioeconomic status, in low-middle income countries (LMICs), with Lebanon as an exemplar. This "cocktail" of carcinogenic exposures warrants the pressing need to understand the complex etiology of lung malignancies developing in LMICs such as Lebanon.

Regional genomic copy number alterations (CNA) are observed in the vast majority of cancers. Besides specifically targeting well-known, canonical oncogenes, CNAs may also play more subtle roles in terms of modulating genetic potential and broad gene expression patterns of developing tumors. Any significant differences in the overall CNA patterns between different cancer types may thus point towards specific biological mechanisms acting in those cancers. In addition, differences among CNA profiles may prove valuable for cancer classifications beyond existing annotation systems. We have analyzed molecular-cytogenetic data from 25579 tumors samples, which were classified into 160 cancer types according to the International Classification of Disease (ICD) coding system. When correcting for differences in the overall CNA frequencies between cancer types, related cancers were often found to cluster together according to similarities in their CNA profiles. Based on a randomization approach, distance measures from the cluster dendrograms were used to identify those specific genomic regions that contributed significantly to this signal. This approach identified 43 non-neutral genomic regions whose propensity for the occurrence of copy number alterations varied with the type of cancer at hand. Only a subset of these identified loci overlapped with previously implied, highly recurrent (hot-spot) cytogenetic imbalance regions. Thus, for many genomic regions, a simple null-hypothesis of independence between cancer type and relative copy number alteration frequency can be rejected. Since a subset of these regions display relatively low overall CNA frequencies, they may point towards second-tier genomic targets that are adaptively relevant but not necessarily essential for cancer development.

Risks for cancer induction by pion radiation in the peak- and plateau region

Cottier, H.; Fritz-Niggli, H.; Froehlich, E.; Heinzell, F.; Nichel, C.; Rao, K.

In the foreground of an evaluation of the suitability of negative protons for cancer therapy there is, beside the analysis of pion effect on malignant cells, also the reaction of healthy tissue. The observation that neutrons at the lowest dose-rate can induce breast cancer and our own results after pion radiation in the peak-region necessitate a broadly planned, urgent investigation of these delayed damages. We will consider radiations at the plateau- and peak-region, the results of which should be of utmost interest for the comparison of neutron- and pion therapy. There are indications that the RBE of a high LET radiation is extremely large for the tumor induction. We will investigate especially the development of mammary cancers in variously aged mice with a low spontaneous tumor rate and C 3 H mice with a high cancer expectancy

To develop and apply a clinical incident taxonomy for radiation therapy. Capturing clinical incident information that focuses on near-miss events is critical for achieving higher levels of safety and reliability. A clinical incident taxonomy for radiation therapy was established; coding categories were prescription, consent, simulation, voluming, dosimetry, treatment, bolus, shielding, imaging, quality assurance and coordination of care. The taxonomy was applied to all clinical incidents occurring at three integrated cancer centres for the years 2011-2015. Incidents were managed locally, audited and feedback disseminated to all centres. Across the five years the total incident rate (per 100 courses) was 8.54; the radiotherapy-specific coded rate was 6.71. The rate of true adverse events (unintended treatment and potential patient harm) was 1.06. Adverse events, where no harm was identified, occurred at a rate of 2.76 per 100 courses. Despite workload increases, overall and actual rates both exhibited downward trends over the 5-year period. The taxonomy captured previously unidentified quality assurance failures; centre-specific issues that contributed to variations in incident trends were also identified. The application of a taxonomy developed for radiation therapy enhances incident investigation and facilitates strategic interventions. The practice appears to be effective in our institution and contributes to the safety culture. The ratio of near miss to actual incidents could serve as a possible measure of incident reporting culture and could be incorporated into large scale incident reporting systems.

To evaluate the feasibility of a mobile screening service model for abdominal aortic aneurysm (AAA) in a remote population centre in Australia. Screening test evaluation. A remote regional centre (population: 20 000) in far western NSW. Men aged 65-74 years, identified from the Australian Electoral roll. A mobile screening service using directed ultrasonography, a basic health check and post-screening consultation. Attendance at the screening program, occurrence of AAA in the target population and effectiveness of screening processes. A total of 516 men without a previous diagnosis of AAA were screened, an estimated response rate of 60%. Of these, 463 (89.7%) had a normal aortic diameter, 28 (5.4%) ectatic and 25 (4.9%) a small, moderate or significant aneurysm. Two men with AAA were recommended for surgery. Feedback from participants indicated that the use of a personalised letter of invitation helped with recruitment, that the screening process was acceptable and the service valued. It is feasible to organise and operate a mobile AAA screening service from moderate sized rural and remote population centres. This model could be scaled up to provide national coverage for rural and remote residents.

Loss of heterozygosity (LOH) at 11q23-qter occurs frequently in ovarian and other cancers, but for colorectal cancer, the evidence is conflicting. Seven polymorphic loci were analyzed between D11S897 and D11S969 in 50 colorectal tumors. Two distinct LOH regions were detected, suggesting possible sites for tumor-suppressor genes involved in colorectal neoplasia: a large centromeric region between D11S897 and D11S925, and a telomeric 4.9-Mb region between D11S912 and D11S969. There was no correlation with clinicopathological features. This analysis describes a region of LOH in the region 11q23.3-24.3 for the first time in colorectal cancer and provides complementary evidence for the ongoing effort to identify the gene(s) involved.

Bloodstream infections (BSIs) are one of the major life-threatening infectious conditions in cancer patients and are responsible for prolonged hospital stays, high healthcare costs and significant mortality. Several clinical trials have reported an improved survival in patients treated with appropriate empirical broad-spectrum antibiotic therapy. Early detection of pathogens and determination of their susceptibility are essential for the optimization of treatment. Variability between hospitals is substantial and requires the individual analysis of local trends. The aim of this study is to assess the local epidemiology of BSI in a single cancer centre over a 10-year period. Retrospective microbiological surveillance of all febrile/infective episodes occurring in oncological and surgical patients in a high-volume cancer centre between January 1999 and December 2008 were considered. Patients' data were collected, processed and analyzed using the epidemiological resource of the Virtuoso Plus software (Metafora Informatica Srl, Milano, Italy). Spearman's rank correlation coefficient, including the two-tailed test of significance, was used to investigate trends of incidence and rate of antibiotic resistance over the 10-year period. A total of 13,058 blood cultures (BCs) were performed in 2,976 patients. BCs were positive in 2,447 tests, representing 740 infective/febrile episodes: 358 (48%) in medical oncology and 382 (52%) in surgical wards. Gram-positives were responsible for the majority of episodes in oncological and surgical divisions (about 63% and 55%, respectively). Gram-positives were also the most common organism in non-catheter-related BSIs (CRBSIs) both in medical oncology (75%) and in surgical divisions (50%). Enterococci showed an increased resistance to levofloxacin, from 5.6% to 25.7% (p = 0.02) and to erythromycin, from 41.7% to 61.4%, (p = 0.05). Similarly, coagulase negative staphylococci (CoNS) developed resistance to levofloxacin and ciprofloxacin

An epidemiological study is being undertaken at Lucas Heights Science and Technology Centre (LHSTC) where the only nuclear reactor in Australia has been in operation since 1958. The study is part of an international collaborative study coordinated by the International Agency for Research on Cancer (IARC), and has dual objectives, first to assess whether workers at LHSTC have had different levels of mortality or cancer incidence from the New South Wales and the Australian populations, and second, as part of the IARC study, to estimate as precisely as possible, through collaboration with IARC, the risk of contracting cancer from low-level, long-term exposure to ionising radiation. The research project is a retrospective cohort study based on records of employment and exposure to radiation kept at LHSTC since 1957. Electronic linkage of all the available dosimetry and employment information with national registers of cancer incidence and mortality is being undertaken for the cohort of LHSTC workers, to allow for a passive follow-up of more than 7000 workers employed from 1957 onwards

IDENTIFICATION OF THOSE VARIABLES THAT HAVE A SIGNIFICANT INFLUENCE ON THE EXPECTED NUMBER OF DAYS OF STAYING IN THE CENTRE DEVELOPMENT REGION OF ROMANIA

2010-06-01

Full Text Available I started from the assumption that there are more variables that have a significant influence on the expected number of days of staying in the Centre Development Region. To identify those variables this paper includes the analysis of variance with two variables that are not interacting, in this case the dependent variable is the question "How many days did you plan to stay in Centre Development Region?" and the independent variables are: "What is the purpose of your stay?" "What is the highest level of education?". Given that there are cases when interactions occur between variables, I also analyzed the interaction effects between the two independent variables. The paper also includes an ANOVA analysis with three variables between which interactions relationships occur. After identifying the dependency relations between the variables I found that the inclusion of the third variable, namely the "Marital status" of respondents, adds value to the model. Following the results obtained by ANOVA analysis, I identified those socio-demographic characteristics that, in my opinion, companies that operate on tourist market in the Center Development Region should consider when fundamenting marketing strategies in tourism.

Prostaglandin (PG) E 2 plays a critical role in colorectal cancer (CRC) progression, including epithelial-mesenchymal transition (EMT). Activity of the rate-limiting enzyme for PGE 2 catabolism (15-hydroxyprostaglandin dehydrogenase [15-PGDH]) is dependent on availability of NAD+. We tested the hypothesis that there is intra-tumoral variability in PGE 2 content, as well as in levels and activity of 15-PGDH, in human CRC liver metastases (CRCLM). To understand possible underlying mechanisms, we investigated the relationship between hypoxia, 15-PGDH and PGE 2 in human CRC cells in vitro. Tissue from the periphery and centre of 20 human CRCLM was analysed for PGE 2 levels, 15-PGDH and cyclooxygenase (COX)-2 expression, 15-PGDH activity, and NAD+/NADH levels. EMT of LIM1863 human CRC cells was induced by transforming growth factor (TGF) β. PGE 2 levels were significantly higher in the centre of CRCLM compared with peripheral tissue (P = 0.04). There were increased levels of 15-PGDH protein in the centre of CRCLM associated with reduced 15-PGDH activity and low NAD+/NADH levels. There was no significant heterogeneity in COX-2 protein expression. NAD+ availability controlled 15-PGDH activity in human CRC cells in vitro. Hypoxia induced 15-PGDH expression in human CRC cells and promoted EMT, in a similar manner to PGE 2 . Combined 15-PGDH expression and loss of membranous E-cadherin (EMT biomarker) were present in the centre of human CRCLM in vivo. There is significant intra-tumoral heterogeneity in PGE 2 content, 15-PGDH activity and NAD+ availability in human CRCLM. Tumour micro-environment (including hypoxia)-driven differences in PGE 2 metabolism should be targeted for novel treatment of advanced CRC

Radiotherapy is an effective treatment for the postoperative loco-regional recurrence of esophageal cancer; however, the optimal treatment field remains controversial. This study aims to evaluate the outcome of local field radiotherapy without elective nodal irradiation for postoperative loco-regional recurrence of esophageal cancer. We retrospectively investigated 35 patients treated for a postoperative loco-regional recurrence of esophageal cancer with local field radiotherapy between December 2008 and March 2016. The median irradiation dose was 60 Gy (range: 50-67.5 Gy). Thirty-one (88.6%) patients received concurrent chemotherapy. The median follow-up period was 18 months (range: 5-94 months). The 2-year overall survival was 55.7%, with a median survival time of 29.9 months. In the univariate analysis, the maximal diameter ≤20 mm (P = 0.0383), solitary lesion (P = 0.0352), and the complete remission after treatment (P = 0.00411) had a significantly better prognosis. A total of 27 of 35 patients (77.1%) had progressive disease (loco-regional failure [n = 9], distant metastasis [n = 7], and both loco-regional failure and distant metastasis [n = 11]). No patients had Grade 3 or greater mucositis. Local field radiotherapy is a considerable treatment option for postoperative loco-regional recurrence of esophageal cancer. © The Author 2017.

Cordier, Bertrand

1992-01-01

This research thesis reports the detailed presentation of the SIGMA telescope, and its use for the observation of the galactic centre region. The SIGMA (gamma imagery system with random mask) telescope is based on an imagery technique using a coded aperture mask, and comprises three main components: the code-mask which modulates information and defines the experiment angular resolution, a position detector which provides the coordinates of the point of interaction of photons and their energy, and allows images to be built up, and active and passive shielding to reduce the background noise. The telescope operating modes and performance (space resolution, angular resolution, camera energy response, sensitivity) are presented. The data reduction procedure is described. Then, the author presents the Galaxy centre, discusses previous observations, and reports and comments new observations performed by using SIGMA [fr

Transcription Restores DNA Repair to Heterochromatin, Determining Regional Mutation Rates in Cancer Genomes

Christina L. Zheng

2014-11-01

Full Text Available Somatic mutations in cancer are more frequent in heterochromatic and late-replicating regions of the genome. We report that regional disparities in mutation density are virtually abolished within transcriptionally silent genomic regions of cutaneous squamous cell carcinomas (cSCCs arising in an XPC−/− background. XPC−/− cells lack global genome nucleotide excision repair (GG-NER, thus establishing differential access of DNA repair machinery within chromatin-rich regions of the genome as the primary cause for the regional disparity. Strikingly, we find that increasing levels of transcription reduce mutation prevalence on both strands of gene bodies embedded within H3K9me3-dense regions, and only to those levels observed in H3K9me3-sparse regions, also in an XPC-dependent manner. Therefore, transcription appears to reduce mutation prevalence specifically by relieving the constraints imposed by chromatin structure on DNA repair. We model this relationship among transcription, chromatin state, and DNA repair, revealing a new, personalized determinant of cancer risk.

In Latin America radiotherapy quality varies significantly among hospitals, where highly equipped academic centers coexist with others not meeting minimal requirements. In 2007, the International Atomic Energy Agency published guidelines for auditing radiotherapy centers, known as the “Quality Assurance Team for Radiation Oncology” (QUATRO) audits. The present report summarizes a pilot experience with QUATRO audits to 12 radiotherapy centres. The findings from QUATRO audits conducted in 12 radiotherapy centres in Latin America between 2008 and 2013 were analysed. Events representing weaknesses or gaps in the process of radiotherapy were recorded. Relevant data for estimating human and technological needs of visited centres were processed. The main difficulties and strengths faced by institutions were also documented. All 12 radiotherapy centres were successfully audited following the QUATRO method. IAEA provided a dosimetry kit for quality control. Forty percent of audited institutions were immersed in a health system that did not recognize cancer as a public health priority problem. With few exceptions, local training programs for physicists and technologists were scarce and research was not an activity of interest among physicians. Centres were provided with sufficient staff to meet the local demand, both in the case of radiation oncologists, physicists and radiation therapists. Three centres lacking the minimum infrastructure were identified. Three institutions did not perform gynaecological brachytherapy, and one installation delivered around 900 teletherapy treatments annually without simulation, planning or dosimetry equipment for that purpose. Recommendations to centres were classified as related to personnel, infrastructure, processes and institutional organizational aspects. Many recommendations warned governments about the evident need for allocating more budgetary resources to radiotherapy. Most recommendations pointed out different aspects related

Full Text Available Introduction: Colorectal cancers are a common disease of oncological practice. A raising incidence is seen in Asian population. It is one of the cancers where screening and early diagnosis are possible. Very few articles are there about the cancer scenario in India. A study of the disease profile helps in screening, early diagnosis and management of the disease in developing countries. Aim: To study the cancer presentation in our population which can help in developing strategies for better control of disease. Material and Methods: Medical records of 171 patients registered at Kidwai Hospital from 2010 to 2012 were retrospectively reviewed. Data including age at presentation, sex, location of the cancer and stage at presentation were analyzed. Results: The male to female ratio was 1.26:1 in rectal cancer. In colon cancer the ratio was 1:1.3. The mean age at presentation was 47 years in males and 51 years in females in colorectal cancers together. Thirty eight percent of the patients were less than 45 years old. Eighty percent of the cases were rectal cancers. In 71% of rectal cancers the growth was located within 5cm from anal verge (AV. Stage III was the commonest stage of presentation. Abdominoperineal resection (APR was the commonest surgical procedure done. Inoperability was highest with lower rectal cancer. Conclusion: Younger age at presentation, low lying rectal cancers and advanced stage at presentation were observed in our study group which includes predominantly rural population. Rectal cancers are the most common cancers referred among colorectal cancers. Screening for colorectal cancers and early evaluation of symptomatic cases need to be encouraged. Patients should be educated regarding this. Screening strategies, etiopathogenesis and genetic abnormalities in colorectal cancer patients need to be defined in developing countries.

MicroRNA genes and their target 3'-untranslated regions are infrequently somatically mutated in ovarian cancers.

Directory of Open Access Journals (Sweden)

Georgina L Ryland

Full Text Available MicroRNAs are key regulators of gene expression and have been shown to have altered expression in a variety of cancer types, including epithelial ovarian cancer. MiRNA function is most often achieved through binding to the 3'-untranslated region of the target protein coding gene. Mutation screening using massively-parallel sequencing of 712 miRNA genes in 86 ovarian cancer cases identified only 5 mutated miRNA genes, each in a different case. One mutation was located in the mature miRNA, and three mutations were predicted to alter the secondary structure of the miRNA transcript. Screening of the 3'-untranslated region of 18 candidate cancer genes identified one mutation in each of AKT2, EGFR, ERRB2 and CTNNB1. The functional effect of these mutations is unclear, as expression data available for AKT2 and EGFR showed no increase in gene transcript. Mutations in miRNA genes and 3'-untranslated regions are thus uncommon in ovarian cancer.

In India approximately 1 million people get burnt every year and most of them are from the lower or middle income strata. Therefore it is obligatory to find out an economic way of treatment for the affected populace. Since use of human skin allograft is the gold standard for the treatment of burn wound, in-house skin banking for a burn unit hospital is prerequisite to make the treatment procedure affordable. Although, there was one skin bank at India till 2009, but it was difficult for a single bank to cover the entire country's need. Looking at the necessities, National Burns Centre (a tertiary burn care centre) along with Rotary International and Euro Skin Bank collaborated and developed an effective cadaveric skin banking model in Mumbai, Maharashtra in 2009. Initial two to three years were formation phase; by the year 2013 the entire system was organized and started running full fledged. The model has also been replicated in other states of India to accommodate the large burn population of the country. This paper therefore, gives a step by step account of how the bank evolved and its present status. Copyright © 2017. Published by Elsevier Ltd.

The aim was to compare a private Commonwealth-initiated regional radiation oncology facility in Toowoomba with a Queensland Health facility (QHF) in Brisbane. The comparison concentrated on staffing, case mix and operational budgets, but was not able to look at changes in access to services. Data were collected from the two facilities from January 2008 to June 2008 inclusive. A number of factors were compared, including case mix, staffing levels, delay times for treatment, research, training and treatment costs. The case mix between the two areas was similar with curative treatments making up just over half the work load in both centres and two-thirds the work being made up of cancers of breast and prostate. Staffing levels were leaner in Toowoomba, especially in the areas of nursing, administration and trial coordinators. Research activity was slightly higher in Toowoomba. The average medicare cost per treatment course was similar in both centres ($5000 per course). Total costs of an average treatment including patient, State and Commonwealth costs, showed a 30% difference in costing favouring Toowoomba. This regional radiation oncology centre has provided state-of-the-art cancer care that is close to home for patients living in the Darling Downs region. Both public and private patients have been treated with modest costs to the patient and significant savings to QH. The case mix is similar to the QHF, and there has been significant activity in clinical research. A paperless working environment is one factor that has allowed staffing levels to be reduced. Ongoing support from Governments are required if private facilities are to participate in important ongoing staff training.

Results in breast cancer research are reported using study endpoints. Most are composite endpoints (such as locoregional recurrence), consisting of several components (for example local recurrence) that are in turn composed of specific events (such as skin recurrence). Inconsistent endpoint selection and definition might lead to unjustified conclusions when comparing study outcomes. This study aimed to determine which locoregional endpoints are used in breast cancer studies, and how these endpoints and their components are defined. PubMed was searched for breast cancer studies published in nine leading journals in 2011. Articles using endpoints with a local or regional component were included and definitions were compared. Twenty-three different endpoints with a local or regional component were extracted from 44 articles. Most frequently used were disease-free survival (25 articles), recurrence-free survival (7), local control (4), locoregional recurrence-free survival (3) and event-free survival (3). Different endpoints were used for similar outcomes. Of 23 endpoints, five were not defined and 18 were defined only partially. Of these, 16 contained a local and 13 a regional component. Included events were not specified in 33 of 57 (local) and 27 of 50 (regional) cases. Definitions of local components inconsistently included carcinoma in situ and skin and chest wall recurrences. Regional components inconsistently included specific nodal sites and skin and chest wall recurrences. Breast cancer studies use many different endpoints with a locoregional component. Definitions of endpoints and events are either not provided or vary between trials. To improve transparency, facilitate trial comparison and avoid unjustified conclusions, authors should report detailed definitions of all endpoints. © 2014 BJS Society Ltd.

Gastric cancer is the second leading cause of oncologic death worldwide. One of the most noteworthy characteristics of this tumor's epidemiology is the marked decline reported in its incidence and mortality in almost every part of the globe in recent decades. This study sought to describe gastric cancer mortality time trends in Spain's regions for both sexes. Mortality data for the period 1976 through 2005 were obtained from the Spanish National Statistics Institute. Cases were identified using the International Classification of Diseases 9 th and 10 th revision (codes 151 and C16, respectively). Crude and standardized mortality rates were calculated by geographic area, sex, and five-year period. Joinpoint regression analyses were performed to ascertain whether changes in gastric cancer mortality trends had occurred, and to estimate the annual percent change by sex and geographic area. Gastric cancer mortality decreased across the study period, with the downward trend being most pronounced in women and in certain regions situated in the interior and north of mainland Spain. Across the study period, there was an overall decrease of 2.90% per annum among men and 3.65% per annum among women. Generally, regions in which the rate of decline was sharpest were those that had initially registered the highest rates. However, the rate of decline was not constant throughout the study period: joinpoint analysis detected a shift in trend for both sexes in the early 1980s. Gastric cancer mortality displayed in both sexes a downward trend during the study period, both nationally and regionally. The different trend in rates in the respective geographic areas translated as greater regional homogeneity in gastric cancer mortality by the end of the study period. In contrast, rates in women fell more than did those in men. The increasing differences between the sexes could indicate that some risk factors may be modifying the sex-specific pattern of this tumor

Settlement Networks in Polish Spatial Development Regional Plans

Sołtys, Jacek

2017-10-01

In 1999, ten years after the great political changes in Poland, 16 self-governed regions (in Polish: voivodeship) were created. According to Polish law, voivodeship spatial development plans, or regional plans in short, determine basic elements of the settlement network. No detailed regulations indicate the specific elements of the settlement network or what features of these elements should be determined. For this reason, centres as elements of the settlement network are variously named in different regions and take the form of various models. The purposes of the research described in this article are: (1) recognition and systematization of settlement network models determined in regional plans; and (2) assessment of the readability of determination in planning and its usefulness in the practice of regional policy. Six models of settlement networks in regional plans have been identified and classified into types and sub-types. Names of specific levels of centres indicate that they were classified according to two criteria: (1) level of services, which concerns only 5 voivodships; and (2) importance in development, which concerns the 11 other voivodships. The hierarchical model referring to the importance of development is less understandable than the one related to services. In the text of most plans, centres of services and centres of development are treated independently from their names. In some plans the functional types of towns and cities are indicated. In some voivodships, specifications in the plan text are too general and seem to be rather useless in the practice of regional policy. The author suggests that regional plans should determine two kinds of centres: hierarchical service centres and non-hierarchical centres of development. These centres should be further distinguished according to: (1) their role in the activation of surroundings; (2) their level of development and the necessity of action for their development; and (3) the types of actions

Background: In recent decades the amount of new breast cancer cases in the southern region has been reported to increase more rapidly than in the northernVietnam. The aim of this study is to compare breast cancer risk factors between the two regions and establish if westernized influences have an impact on any reported differences. Method: Data was collected from the two largest oncology hospitals in the north and the south of Vietnam in 2015. Breast density, demographic, reproductive and lifestyle data of 127 cases and 269 controls were collected in the north and 141 cases and 250 controls were gathered from the south. Baseline differences in factors between cases and age-matched controls in each region were assessed using chi-square tests and independent t-tests. Odds ratios (OR) for independent risk factors for breast cancer were obtained from conditional logistic regression. Results: In northern Vietnam significantly increased risks in developing breast cancer were observed for women with age at first menstrual period less than 14 years old (OR=2.1; Pcup of coffee per day (OR=1.9; P<0.05) were more likely to be diagnosed with breast cancer. Conclusion: We found that women living in the south had some breast cancer associations, such as increased mammographic density and coffee consumption, which are closer to the risks in westernized populations than women in the north.

Aim: The aim of this study was to analyse the radiographic findings of the screening mammograms of women with interval cancer who participated in a multi-centre, randomized, controlled trial of mammographic screening in women from age 40-48 years. Materials and methods: The screening and diagnostic mammograms of 208 women with interval cancers were reviewed. Abnormalities were classified as malignant, subtle and non-specific. Results: Eighty-seven (42%) of women had true, 66 (32%) occult and 55 (26%) false-negative interval cancers. The features most frequently missed or misinterpreted were granular microcalcification (38%), asymmetric density (27%) and distortion (22%). Thirty-seven percent of abnormal previous screens were classified as malignant, 39% subtle change and 21% as non-specific. Granular calcifications were significantly more common on the diagnostic mammograms of false-negative interval cancers than those of true interval cancers (28 versus 14%, p = 0.04). Occult interval cancers were more likely to be <10 mm and <15 mm in invasive pathological size than other interval cancers (p = 0.03 and 0.005, respectively). True interval cancers were more likely to be histologically grade 3 than other interval cancers (p = 0.04). Women who developed true and false-negative interval cancers had similar background patterns, but women with occult cancers had a higher proportion of dense patterns (p < 0.05). Conclusion: Interval cancers in a young screening population have a high proportion of occult lesions that are small and occur in dense background patterns. The proportion of interval cancers that are false negative is similar that seen in older populations and granular microcalcification is the commonest missed mammographic feature

Full Text Available The Asian Prostate Cancer (A-CaP Study is an Asia-wide initiative that has been developed over the course of 2 years. The A-CaP Study is scheduled to begin in 2016, when each participating country or region will begin registration of newly diagnosed prostate cancer patients and conduct prognosis investigations. From the data gathered, common research themes will be identified, such as comparisons among Asian countries of background factors in newly diagnosed prostate cancer patients. This is the first Asia-wide study of prostate cancer and has developed from single country research efforts in this field, including in Japan and Korea. The inaugural Board Meeting of A-CaP was held on December 11, 2015 at the Research Center for Advanced Science and Technology, The University of Tokyo, attended by representatives of all participating countries and regions, who signed a memorandum of understanding concerning registration for A-CaP. Following the Board Meeting an A-CaP Launch Symposium was held. The symposium was attended by representatives of countries and regions participating in A-CaP, who gave presentations. Presentations and a keynote address were also delivered by representatives of the University of California San Francisco, USA, and the Peter MacCallum Cancer Centre, Australia, who provided insight and experience on similar databases compiled in their respective countries.

Purpose: To assess whether online adaptive radiotherapy for bladder cancer is feasible across multiple Radiation Oncology departments using different imaging, delivery and recording technology. Materials and methods: A multi-centre feasibility study of online adaptive radiotherapy, using a choice of three “plan of the day”, was conducted at 12 departments. Patients with muscle-invasive bladder cancer were included. Departments were activated if part of the pilot study or after a site-credentialing visit. There was real time review of the first two cases from each department. Results: 54 patients were recruited, with 50 proceeding to radiotherapy. There were 43 males and 7 females with a mean age of 78 years. The tumour stages treated included T1 (1 patient), T2 (35), T3 (10) and T4 (4). One patient died of an unrelated cause during radiotherapy. The three adaptive plans were created before the 10th fraction in all cases. In 8 (16%) of the patients, a conventional plan using a ‘standard’ CTV to PTV margin of 1.5 cm was used for one or more fractions where the pre-treatment bladder CTV was larger than any of the three adaptive plans. The bladder CTV extended beyond the PTV on post treatment imaging in 9 (18%) of the 49 patients. Conclusions: From a technical perspective an online adaptive radiotherapy technique can be instituted in a multi-centre setting. However, without further bladder filling control or imaging, a CTV to PTV margin of 7 mm is insufficient

In Latin America, gastric cancer is a leading cancer, and countries in the region have some of the highest mortality rates worldwide, including Chile, Costa Rica, and Colombia. Geographic variation in mortality rates is observed both between neighboring countries and within nations. We discuss epidemiological observations suggesting an association between altitude and gastric cancer risk in Latin America. In the Americas, the burden of gastric cancer mortality is concentrated in the mountainous areas along the Pacific rim, following the geography of the Andes sierra, from Venezuela to Chile, and the Sierra Madre and Cordillera de Centroamérica, from southern Mexico to Costa Rica. Altitude is probably a surrogate for host genetic, bacterial, dietary, and environmental factors that may cluster in the mountainous regions. For example, H. pylori strains from patients of the Andean Nariño region of Colombia display European ancestral haplotypes, whereas strains from the Pacific coast are predominantly of African origin. The observation of higher gastric cancer rates in the mountainous areas is not universal: the association is absent in Chile, where risk is more strongly associated with the age of H. pylori acquisition and socio-economic determinants. The dramatic global and regional variations in gastric cancer incidence and mortality rates offer the opportunity for scientific discovery and focused prevention programs.

Regional differences in incidence of gastric and colonic cancer in the Maori of New Zealand

Thompson, A

2002-01-01

Background: It is known that there are ethnic differences in cancer in New Zealand between Maori (the indigenous people) and non-Maori, however, until now no regional comparisons have been made. Study design: A retrospective study of patients diagnosed at Whangarei Hospital, New Zealand between 1995 and 1997 with gastric or colonic cancer was combined with population data from the 1996 census for Whangarei District to calculate incidence figures. The incidence of cancer was compared to national rates. Results: Between 1995 and 1997, 19 Maori and 24 non-Maori were diagnosed with gastric cancer, and 10 Maori and 125 non-Maori with colonic cancer. The age standardised rates (per 100 000) for Maori and non-Maori with gastric caner were 68.3 and 7.9 respectively. Gastric cancer is known to be increased in the Maori, but in Whangarei was significantly higher than the national Maori rates (20.5). There was no difference in the rate of colonic cancer in the Maori and non-Maori in Whangarei, again this differs from the national trends, in which the Maori are protected against cancer. Conclusion: This study highlights that there is still much more to be learnt in understanding the aetiology of gastrointestinal cancers, to explain such strong regional differences. PMID:12151659

Objective Delegation and skill sharing are emerging service strategies for allied health (AH) professionals working in Queensland regional cancer care services. The aim of the present study was to describe the consistency between two services for the types and frequency of tasks provided and the agreement between teams in the decision to delegate or skill share clinical tasks, thereby determining the potential applicability to other services. Methods Datasets provided by two similar services were collated. Descriptive statistical analyses were used to assess the extent of agreement. Results In all, 214 tasks were identified as being undertaken by the services (92% agreement). Across the services, 70 tasks were identified as high frequency (equal to or more frequently than weekly) and 29 as not high frequency (46% agreement). Of the 68 tasks that were risk assessed, agreement was 66% for delegation and 60% for skill sharing, with high-frequency and intervention tasks more likely to be delegated. Conclusions Strong consistency was apparent for the clinical tasks undertaken by the two cancer care AH teams, with moderate agreement for the frequency of tasks performed. The proportion of tasks considered appropriate for skill sharing and/or delegation was similar, although variation at the task level was apparent. Further research is warranted to examine the range of factors that affect the decision to skill share or delegate. What is known about the topic? There is limited research evidence regarding the use of skill sharing and delegation service models for AH in cancer care services. In particular, the extent to which decisions about task safety and appropriateness for delegation or skill sharing can be generalised across services has not been investigated. What does this paper add? This study investigated the level of clinical task consistency between two similar AH cancer care teams in regional centres. It also examined the level of agreement with regard to

Significant cancer health disparities exist in the United States and Puerto Rico. While numerous initiatives have been implemented to reduce cancer disparities, regional coordination of these efforts between institutions is often limited. To address cancer health disparities nation-wide, a series of regional transdisciplinary networks through the Geographic Management Program (GMaP) and the Minority Biospecimen/Biobanking Geographic Management Program (BMaP) were established in six regions across the country. This paper describes the development of the Region 3 GMaP/BMaP network composed of over 100 investigators from nine institutions in five Southeastern states and Puerto Rico to develop a state-of-the-art network for cancer health disparities research and training. We describe a series of partnership activities that led to the formation of the infrastructure for this network, recount the participatory processes utilized to develop and implement a needs and assets assessment and implementation plan, and describe our approach to data collection. Completion, by all nine institutions, of the needs and assets assessment resulted in several beneficial outcomes for Region 3 GMaP/BMaP. This network entails ongoing commitment from the institutions and institutional leaders, continuous participatory and engagement activities, and effective coordination and communication centered on team science goals.

It is well understood nowadays that changes in the mammographic parenchymal pattern are an indicator of a risk of breast cancer and we have developed a statistical method that estimates the mammogram regions where the parenchymal changes, due to breast cancer, occur. This region of interest is computed from a score map by utilising the anatomical breast coordinate system developed in our previous work. The method also makes an automatic scale selection to avoid overfitting while the region estimates are computed by a nested cross-validation scheme. In this way, it is possible to recover those mammogram regions that show a significant difference in classification scores between the cancer and the control group. Our experiments suggested that the most significant mammogram region is the region behind the nipple and that can be justified by previous findings from other research groups. This result was conducted on the basis of the cross-validation experiments on independent training, validation and testing sets from the case-control study of 490 women, of which 245 women were diagnosed with breast cancer within a period of 2-4 years after the baseline mammograms. We additionally generalised the estimated region to another, mini-MIAS study and showed that the transferred region estimate gives at least a similar classification result when compared to the case where the whole breast region is used. In all, by following our method, one most likely improves both preclinical and follow-up breast cancer screening, but a larger study population will be required to test this hypothesis.

Full text: The Australian Centre for Radiofrequency Bioeffects Research (ACRBR) is a newly established multi-institutional research centre which seeks to research questions pertaining to possible health effects of exposure to radiofrequency devices, such as mobile phones and which is funded under the Australian National Health and Medical Research Council (NHMRC) Centres of Research Excellence funding program. The Centre of Research Excellence in Electromagnetic Energy is combining the efforts of engineers, epidemiologists, physicists, psychophysiologists and veterinary pathologists from RMIT University, the Institute of Medical and Veterinary Science in South Australia (IMVS), Monash University, Swinburne University of Technology and Telstra Research Laboratories (TRL). The centre is funded at $2.5 M over five years and will undertake a program of research to address the issue of exposure to radiofrequency (RF) devices and health. It will also train new scientists, keep the community informed of ongoing developments and help the development of government policies in this area of considerable public concern. The 5-year program has the following components: Neurobiology: One important area where there is a perceived research gap is in the area of potential neurological effects, which will hence be a major focus of this Centre. The proposed studies range from in vitro and in vivo research studies of RF effects on neuron and neural system functioning in rodents, to that of RF effects on simple neural function, cognition and subjective report in humans. The latter series of studies have been developed to account for the consensus view that more emphasis needs to be placed on possible differences in RF population sensitivity (e.g. youth versus aged, and ' electromagnetic hypersensitives'). Epidemiological studies are an important tool in studying the impact on public health from exposure of whole populations to modern radio technologies. Cancer outcomes in this area of

It is well known for alkali halides doped with divalent metal impurities that exposure to high energetic radiation and subsequent F band bleaching leads to the formation of Z 1 centres. Optical absorption measurements have shown that a low concentration of Z 1 centres is produced along with F centres during irradiation without any optical bleaching. Now the question is whether Z 1 centres are really formed along with F centres during irradiation. The aim of the present paper was to study the formation of a small amount of Z 1 centres during irradiation with the help of optical absorption and thermoluminescence measurements. The crystals of KCl:Sr were exposed to γ-rays for different doses. The TL curve for the crystal exposed to a minimum dose of γ-rays shows a TL peak at 457 K and a weak shoulder in the region 400 K to 408 K. The TL curve of the crystal exposed to maximum dose of rays shows the peak at 408 K with a greater intensity. Upon F band bleaching 408 K peak increases in intensity and optical absorption is also broadened. It is shown that the peak at 457 K is due to F centres and the peak at 408 K is due to Z 1 centres. These results clearly show that a small anount of Z 1 centres is really formed along with F centres during irradiation. (author)

Abstract In this implementation phase of the European Cancer Patient’s Bill of Rights (BoR), we confirm the following three patient-centred principles that underpin this initiative:The right of every European citizen to receive the most accurate information and to be proactively involved in his/her care.The right of every European citizen to optimal and timely access to a diagnosis and to appropriate specialised care, underpinned by research and innovation.The right of every European citizen to receive care in health systems that ensure the best possible cancer prevention, the earliest possible diagnosis of their cancer, improved outcomes, patient rehabilitation, best quality of life and affordable health care. The key aspects of working towards implementing the BoR are:Agree our high-level goal. The vision of 70% long-term survival for patients with cancer in 2035, promoting cancer prevention and cancer control and the associated progress in ensuring good patient experience and quality of life.Establish the major mechanisms to underpin its delivery. (1) The systematic and rigorous sharing of best practice between and across European cancer healthcare systems and (2) the active promotion of Research and Innovation focused on improving outcomes; (3) Improving access to new and established cancer care by sharing best practice in the development, approval, procurement and reimbursement of cancer diagnostic tests and treatments.Work with other organisations to bring into being a Europe based centre that will (1) systematically identify, evaluate and validate and disseminate best practice in cancer management for the different countries and regions and (2) promote Research and Innovation and its translation to maximise its impact to improve outcomes.

Early 1958 the Brazilian representative on the Board of Governors of the International Atomic Energy Agency - supported by the Governors from Argentina and Guatemala -proposed that a study should be made of the possibility of setting up one or more atomic energy training centres in Latin America. On the Board's recommendation, the Director General of the Agency appointed a fact-finding team to make anon-the-spot study. In drafting this report the team was invited to consider the following points: (a) The need for establishing one or more regional training centres; (b) Existing facilities that are being or could be used for training, together with technical data concerning them; (c) The general scientific technological and industrial conditions of the countries visited insofar as they have a bearing on their training needs and capabilities. The authors of the report conclude that 'a training centre in radio-botany should provide vitally needed knowledge and vitally needed specialists to all the agricultural installations in Latin America. A training centre like this might provide an excellent model upon which to base training centres in other areas'. The report recommends that: 1. The Agency should meet the requests of Latin American universities by, for example, supplying equipment and sending experts; 2. At least one specialized training centre should be established as soon as possible. Taking as an example the field of radio-botany, such a centre would provide trained specialists in radio-botany to agricultural institutions throughout Latin America and also provide basic research results vital to agriculture. The cost of new facilities might be of the order of $7 500 000, with an annual budget of approximately $650 000. Staff required: 40 scientists and 175 employees; 3. Whenever it appears feasible to gather necessary staff of high creative ability and established productivity and when funds can be made available for facilities, equipment and operating costs, at

This paper describes our process to engage regional stakeholders for prioritizing comparative effectiveness research (CER) in cancer diagnostics. We also describe a novel methodology for incorporating stakeholder data and input to inform the objectives of selected CER studies. As an integrated component to establishing the infrastructure for community-based CER on diagnostic technologies, we have assembled a regional stakeholder group composed of local payers, clinicians and state healthcare representatives to not only identify and prioritize CER topics most important to the western Washington State region, but also to inform the study design of selected research areas. A landscape analysis process combining literature searches, expert consultations and stakeholder discussions was used to identify possible CER topics in cancer diagnostics. Stakeholders prioritized the top topics using a modified Delphi/group-nominal method and a standardized evaluation criteria framework to determine a final selected CER study area. Implementation of the selected study was immediate due to a unique American Recovery and Reinvestment Act funding structure involving the same researchers and stakeholders in both the prioritization and execution phases of the project. Stakeholder engagement was enhanced after study selection via a rapid analysis of a subset of payers' internal claims, coordinated by the research team, to obtain summary data of imaging patterns of use. Results of this preliminary analysis, which we termed an 'internal analysis,' were used to determine with the stakeholders the most important and feasible study objectives. Stakeholders identified PET and MRI in cancers including breast, lung, lymphoma and colorectal as top priorities. In an internal analysis of breast cancer imaging, summary data from three payers demonstrated utilization rates of advanced imaging increased between 2002 and 2009 in the study population, with a great deal of variability in use between

Full Text Available Introduction: Colorectal cancer (CRC has different forms of colon cancer or rectal cancer. CRCs are often considered together because they possess many similar features. A severe form of the disease with higher mortality rate increases with increase in age. The most common CRC risk factors include smoking, diabetes, and obesity. This study aims to evaluate the awareness of CRC in a random population of Asir region and to identify the subpopulation that can be recipients of awareness and screening programs. Material and Methods: Cross-sectional nonprobable random sampling study using a self-administered questionnaire survey which was employed to include healthy males and females from Asir region. The questionnaire included ten questions in Arabic language and data were categorized according to gender, marital status, age, and level of education to determine whether these demographic groups possess difference in knowledge about CRC. Results: Most of the respondents (51% and 71.6% knew what is colon and rectum. About 33.8% know the correct function of the colon while 22.5% know the correct incidence and 22.1% know the correct time of screening for CRC. Very few respondents know the symptoms, risks, and screening modalities of CRC.Pearson's Chi-square test was employed to evaluate the differences in responses in four demographic categories of the study population. P <0.05 was considered as statistically significant Conclusions: Single less educated males lack knowledge of CRC. In addition, there is very low awareness of CRC symptoms, risk factors, and screening modalities among the entire surveyed population.

While cancer remains the scourge of mankind, a large proportion of cases these days are amenable to treatment by irradiation. Bringing new irradiation centres to large concentrations of population is thus a vital task. This was highlighted at the first three-day workshop of the European Light Ion Medical Accelerator (EULIMA) project to assess the potential value of light ion beam therapy. Held in November at the Antoine-Lacassagne Centre, Nice, one of twenty cancer centres in France, the workshop was attended by some 60 delegates from Europe, USA, Canada and Japan, representing the fields of physics, radiobiology, radiotherapy and medicine.

Breast cancer formation is associated with frequent changes in DNA methylation but the extent of very early alterations in DNA methylation and the biological significance of cancer-associated epigenetic changes need further elucidation. Pyrosequencing was done on bisulfite-treated DNA from formalin-fixed, paraffin-embedded sections containing invasive tumor and paired samples of histologically normal tissue adjacent to the cancers as well as control reduction mammoplasty samples from unaffected women. The DNA regions studied were promoters (BRCA1, CD44, ESR1, GSTM2, GSTP1, MAGEA1, MSI1, NFE2L3, RASSF1A, RUNX3, SIX3 and TFF1), far-upstream regions (EN1, PAX3, PITX2, and SGK1), introns (APC, EGFR, LHX2, RFX1 and SOX9) and the LINE-1 and satellite 2 DNA repeats. These choices were based upon previous literature or publicly available DNA methylome profiles. The percent methylation was averaged across neighboring CpG sites. Most of the assayed gene regions displayed hypermethylation in cancer vs. adjacent tissue but the TFF1 and MAGEA1 regions were significantly hypomethylated (p ≤0.001). Importantly, six of the 16 regions examined in a large collection of patients (105 – 129) and in 15-18 reduction mammoplasty samples were already aberrantly methylated in adjacent, histologically normal tissue vs. non-cancerous mammoplasty samples (p ≤0.01). In addition, examination of transcriptome and DNA methylation databases indicated that methylation at three non-promoter regions (far-upstream EN1 and PITX2 and intronic LHX2) was associated with higher gene expression, unlike the inverse associations between cancer DNA hypermethylation and cancer-altered gene expression usually reported. These three non-promoter regions also exhibited normal tissue-specific hypermethylation positively associated with differentiation-related gene expression (in muscle progenitor cells vs. many other types of normal cells). The importance of considering the exact DNA region analyzed and the

The New Zealand Ministry of Health (MoH) maintains a number of National Collections, which contain data on diagnoses, procedures and service provision for patients. There are concerns that these collections may underestimate the provision of cancer treatment, but the extent to which this is true is largely unknown. In this brief report, we focus on the Auckland region to illustrate the extent to which the National Collections undercount receipt of surgery in patients with breast, colon or renal cancer, and receipt of chemo- and/or radiotherapy for breast cancer patients with regional extent of disease (all diagnosed 2006-2008). We collected treatment data from the National collections and augmented this with data from Cancer Centres, breast cancer registers, private hospitals and personal clinician databases. The National Collections were used to determine 'baseline' treatment data, and we then compared receipt of treatment to that observed on the augmented dataset. We found that the National Collections undercounted receipt of surgery by 13-19%, and receipt of chemo- or radiotherapy for breast cancer patients by 18% and 16% respectively. Our observations clearly point toward (1) a non-reporting private hospital 'effect' on surgery data completeness; and (2) underreporting of adjuvant therapy to the MoH by service providers.

Orthologous microRNA genes are located in cancer-associated genomic regions in human and mouse.

Directory of Open Access Journals (Sweden)

Igor V Makunin

Full Text Available BACKGROUND: MicroRNAs (miRNAs are short non-coding RNAs that regulate differentiation and development in many organisms and play an important role in cancer. METHODOLOGY/PRINCIPAL FINDINGS: Using a public database of mapped retroviral insertion sites from various mouse models of cancer we demonstrate that MLV-derived retroviral inserts are enriched in close proximity to mouse miRNA loci. Clustered inserts from cancer-associated regions (Common Integration Sites, CIS have a higher association with miRNAs than non-clustered inserts. Ten CIS-associated miRNA loci containing 22 miRNAs are located within 10 kb of known CIS insertions. Only one CIS-associated miRNA locus overlaps a RefSeq protein-coding gene and six loci are located more than 10 kb from any RefSeq gene. CIS-associated miRNAs on average are more conserved in vertebrates than miRNAs associated with non-CIS inserts and their human homologs are also located in regions perturbed in cancer. In addition we show that miRNA genes are enriched around promoter and/or terminator regions of RefSeq genes in both mouse and human. CONCLUSIONS/SIGNIFICANCE: We provide a list of ten miRNA loci potentially involved in the development of blood cancer or brain tumors. There is independent experimental support from other studies for the involvement of miRNAs from at least three CIS-associated miRNA loci in cancer development.

The evidence on the association between politics and health is scarce considering the importance of this topic for population health. Studies that investigated the effect of different political regimes on health outcomes show inconsistent results. Bayesian time-series cross-section analyses are used to examine the overall impact of regional politics on variations in Italian regional life expectancy (LE) at birth during the period 1980-2010. Our analyses control for trends in and unobserved determinants of regional LE, correct for temporal as well as spatial autocorrelation, and employ a flexible specification for the timing of the political effects. In the period from 1980 to 1995, we find no evidence that the communist, left-oriented coalitions and Christian Democratic, centre-oriented coalitions have had an effect on regional LE. In the period from 1995 onwards, after a major reconfiguration of Italy's political regimes and a major healthcare reform, we again find no evidence that the Centre-Left and Centre-Right coalitions have had a significant impact on regional LE. The presented results provide no support for the notion that different regional political regimes in Italy have had a differential effect on regional LE, even though Italian regions have had considerable and increasing autonomy over healthcare and health-related policies and expenditures.

Despite literature supporting a client and family-centred approach to healthcare delivery in paediatric facilities, there is little information about healthcare delivery from the perspective of teenagers in the oncology setting. The objective of this study is to describe the healthcare experiences of teenagers with cancer. As part of a larger study on teen-centred care delivery in paediatric oncology, a survey included several open-ended questions to learn about the following: (1) what teenagers liked about the cancer care they received; (2) what they disliked about the cancer care received; and (3) what they would include if they could design the perfect cancer centre for teenagers. The survey was completed by 200 teenagers (aged 12-20 years) from three paediatric hospitals in Canada. Answers to these questions were coded and developed into themes and subthemes using a thematic analysis approach. The number of patients providing answers was 89% for question 1, 63% for question 2 and 68.5% for question 3. Likes and dislikes were conceptualized in terms of four key themes as follows: (1) staff at the treatment centre; (2) the cancer care they received; (3) the treatment centre itself; and (4) social activities. The most common suggestions for the perfect cancer centre included having access to better entertainment, more social opportunities to interact with peers, and a more comfortable environment for themselves and their families. Understanding teenagers' experiences in the paediatric oncology setting provides information that could be used to shape the delivery of healthcare in a way that is tailored to their needs. Further research in this area is required in order to improve existing oncology care. © 2013 John Wiley & Sons Ltd.

Purpose To examine the factors associated with gynecologic cancer mortality risks, to estimate the mortality-to-incidence rate ratios (MIR) in Trinidad and Tobago (TT), and to compare the MIRs to those of select countries. Methods Data on 3,915 incident gynecologic cancers reported to the National Cancer Registry of TT from 1 January 1995 to 31 December 2009 were analyzed using proportional hazards models to determine factors associated with mortality. MIRs for cervical, endometrial, and ovarian cancers were calculated using cancer registry data (TT), GLOBOCAN 2012 incidence data, and WHO Mortality Database 2012 data (WHO regions and select countries). Results Among the 3,915 incident gynecologic cancers diagnosed in TT during the study period, 1,795 (45.8%) were cervical, 1,259 (32.2%) were endometrial, and 861 (22.0%) were ovarian cancers. Older age, African ancestry, geographic residence, tumor stage, and treatment non-receipt were associated with increased gynecologic cancer mortality in TT. Compared to GLOBOCAN 2012 data, TT MIR estimates for cervical (0.49 vs. 0.53), endometrial (0.61 vs. 0.65), and ovarian cancers (0.32 vs. 0.48) were elevated. While the Caribbean region had intermediate gynecologic cancer MIRs, MIRs in TT were among the highest of the countries examined in the Caribbean region. Conclusions Given its status as a high-income economy, the relatively high gynecologic cancer MIRs observed in TT are striking. These findings highlight the urgent need for improved cancer surveillance, screening, and treatment for these (and other) cancers in this Caribbean nation. PMID:28917021

Unsafe drinking water, unimproved sanitation and lack of hygiene pose health risks, particularly to children in low- and middle-income countries. This study aimed to assess the prevalence and risk factors of intestinal parasitic infections in school-aged children in two regions of Burkina Faso. A cross-sectional survey was carried out in February 2015 with 385 children aged 8-14 years from eight randomly selected schools in the Plateau Central and Centre-Ouest regions of Burkina Faso. Stool samples were subjected to the Kato-Katz and a formalin-ether concentration method for the diagnosis of helminths and intestinal protozoa infections. Urine samples were examined with a urine filtration technique for Schistosoma haematobium eggs. Water samples from community sources (n = 37), children's households (n = 95) and children's drinking water cups (n = 113) were analysed for contamination with coliform bacteria and faecal streptococci. Data on individual and family-level risk factors were obtained using a questionnaire. Mixed logistic regression models were employed to determine factors associated with intestinal parasitic infections in schoolchildren. Intestinal parasitic infections were highly prevalent; 84.7 % of the children harboured intestinal protozoa, while helminth infections were diagnosed in 10.7 % of the children. We found significantly lower odds of pathogenic intestinal protozoa infection (Entamoeba histolytica/E. dispar and Giardia intestinalis) among children from the Plateau Central, compared to the Centre-Ouest region (P parasitic infections in children. Intestinal protozoa but not helminths were highly prevalent among schoolchildren in randomly selected schools in two regions of Burkina Faso. Our findings call for specific public health measures tailored to school-aged children and rural communities in this part of Burkina Faso. It will be interesting to assess the effect of water, sanitation and hygiene interventions on the

Objective: The complexity of radiotherapy planning is increasing rapidly. Delivery and planning is subject to detailed quality assurance (QA) checks. The weakest link is often the oncologists' delineation of the clinical target volume (CTV). Weekly departmental meetings for radiotherapy QA (RTQA) were introduced into the Royal Wolverhampton Hospital, Wolverhampton, UK, in October 2011. This article describes the impact of this on patient care. Methods: CTVs for megavoltage photon radiotherapy courses for all radical, adjuvant and palliative treatments longer than five fractions (with the exception of two field tangential breast treatments not enrolled into clinical trials) were reviewed in the RTQA meeting. Audits were carried out in January 2012 (baseline) and September 2013, each over a 4-week period. Adherence to departmental contouring protocols was assessed and the number of major and minor alterations following peer review were determined. Results: There was no statistically significant difference for major alterations between the two study groups; 8 alterations in 80 patients (10%) for the baseline audit vs 3 alterations from 72 patients (4.2%) in the second audit (p = 0.17). A trend towards a reduction in alterations following peer review was observed. There has, however, been a change in practice resulting in a reduction in variation in CTV definition within our centre and greater adherence to protocols. There is increasing confidence in the quality and constancy of care delivered. Conclusion: Introduction of a weekly QA meeting for target volume definition has facilitated consensus and adoption of departmental clinical guidelines within the unit. Advances in knowledge: The weakest areas in radiotherapy are patient selection and definition of the CTV. Engagement in high-quality RTQA is paramount. This article describes the impact of this in one UK cancer centre. PMID:25251520

Nanocrystalline CeO 2 powders were synthesized by two cost-effective methods: the self-propagating room temperature (SPRT) method and the precipitation method. Differently prepared samples exhibited different temperature-dependent photoluminescence (PL) in the ultraviolet and visible regions. The PL signals originated from different kinds of oxygen-deficient defect centres with or without trapped electrons (F 0 , F + or F ++ centres). The temperature-dependent PL spectra were measured using different excitation lines, below (457, 488 and 514 nm) or comparable (325 nm) to the ceria optical band gap energy, in order to investigate the positions of intragap localized defect states. Evidence for the presence of F + centres was supported by the signals observed in electron paramagnetic resonance (EPR) measurements. Based on PL and EPR measurements it was shown that F + centres dominate in the CeO 2 sample synthesized by the SPRT method, whereas F 0 centres are the major defects in the CeO 2 sample synthesized by the precipitation method. The luminescence from F ++ states, as shallow trap states, was registered in both samples. Energy level positions of these defect states in the ceria band gap were proposed. (paper)

Transparency in armaments, regional dialogue and disarmament

International Nuclear Information System (INIS)

1994-01-01

In the face of recent fundamental changes in the international situation, regional and subregional issues have acquired additional urgency and importance in the field of disarmament and international security. The pursuit of regional solutions to regional problems is thus being encouraged by the international community. Towards this end, the United Nations Centre for Disarmament Affairs is seeking to promote regional approaches to disarmament either through the United Nations Regional Centres for Peace and Disarmament or in cooperation with individual Governments. Regional conferences, meetings and seminars to facilitate exchange of ideas and information between governmental and non-governmental sectors, and between governmental and other experts, have been organized as a means of finding common ground, fostering the process of confidence-building and delineating areas of possible future negotiation and agreement. Within this framework, a Conference on the theme 'Transparency in armaments, regional dialogue and disarmament' was held in Hiroshima, Japan. The Conference, the second one held in Hiroshima on disarmament issues, was organized by the Centre for Disarmament Affairs through the Regional Centre for Peace and Disarmament in Asia and the Pacific and in collaboration with the Government of Japan and the Prefecture and City of Hiroshima. This publication is based on material presented at that Conference

An international and interdisciplinary centre of experimental physics in the Alps-Danube-Adria region (the 'AUSTRON' project)

1992-01-01

The basic idea of the 'AUSTRON' Project is to create an international and interdisciplinary centre of excellence, devoted to fundamental and applied research in the field of experimental physics and related topics of high technology RandD. Three alternatives have been proposed as the basic facility of this centre: either an electron-positron ring collider for a tau-charm factory, or a smaller ring for a phi factory, or a proton accelerator for a spallation source. That should be complemented by a synchrotron radiation facility, constituting an important link between physics, biology, medicine and the industry. 'AUSTRON' should also include a test beam facility for radiation detector development, a RandD laboratory for micro-electronics, a scientific computing centre linked to international networks, and a centre of education.

Full Text Available In the situation where a large increase in trade and freight transport volumes in the Baltic Sea region (BSR is expected and in which the BSR is facing a major economic restructuring, eff orts to achieve more integrated and sustainable transport and communication links within the BSR are needed. One of these eff orts is the development of logistics centres (LCs and their networking, which will continue to have an impact on improving communication links, spatial planning practices and approaches, logistics chain development and the promotion of sustainable transport modes. These factors will refl ect on logistics processes both in major gateway cities and in remote BSR areas. The importance of logistics systems as a whole is not seen clearly enough. Logistics actors see that logistics operations are not appreciated as much as other fi elds of activity. In addition, logistics centres and the importance of logistics activities to the business life of areas and the employment rate should be brought up better. In the paper main goal and tasks of national approach to LCs development are discussed. Strategic focus of new activities in this area is on the integration of various networks within and between logistics centres in order to improve and develop the quality of logistics networks as well as to spatially widen the networking activities. The key objectives are to integrate the links between logistics centres, ports and other logistics operators in a functional and sustainable way, to promote spatial integration by creating sustainable and integrated approaches to spatial planning of logistics centres and transport infrastructure, to improve ICT-based networking and communication practices of the fi elds of transport and logistics and to increase the competence of logistics centres and associated actors by organising educational and training events. The current activities include, for example, the creation of measures for transport networking and

Prognosis remains poor with most patients presenting with advanced or metastatic disease. A better understanding of angiogenesis has led to the investigation of drugs that inhibit the vascular endothelial growth factor (VEGF pathway including anti-VEGF antibody therapy (eg, bevacizumab, inhibitors of angiogenic receptor tyrosine kinases (eg, sunitinib, sorafenib, apatinib, regorafenib, and inhibitors of vascular endothelial growth factor receptors (VEGFRs (eg, ramucirumab. Ramucirumab, a VEGFR-2 inhibitor, is the first anti-angiogenic agent approved by the US Food and Drug Administration for use in the treatment of advanced gastric cancers. This review will focus on the clinical utility and potential use of ramucirumab in advanced gastric cancer.

Stevens Johnson Syndrome/toxic epidermal necrolysis (SJS/TEN) are rare, potentially fatal desquamative disorders characterised by large areas of partial thickness skin and mucosal loss. The degree of epidermal detachment that occurs has led to SJS/TEN being described as a burn-like condition. These patients benefit from judicious critical care, early debridement and meticulous wound care. This is best undertaken within a multidisciplinary setting led by clinicians experienced in the management of massive skin loss and its sequelae. In this study, we examined the clinical outcomes of SJS/TEN overlap & TEN patients managed by our regional burns service over a 12-year period. We present our treatment model for other burn centres treating SJS/TEN patients. A retrospective case review was performed for all patients with a clinical diagnosis of TEN or SJS/TEN overlap admitted to our paediatric and adult burns centre between June 2004 and December 2016. Patient demographics, percentage total body surface area (%TBSA), mucosal involvement, causation, severity of illness score (SCORTEN), length of stay and survival were appraised with appropriate statistical analysis performed using Graph Pad Prism 7.02 Software. During the study period, 42 patients (M26; F: 16) with TEN (n=32) and SJS/TEN overlap (n=10) were managed within our burns service. Mean %TBSA of cutaneous involvement was 57% (range 10-100%) and mean length of stay (LOS) was 27 days (range 1-144 days). We observed 4 deaths in our series compared to 16 predicted by SCORTEN giving a standardised mortality ratio (SMR) of 24%. Management in our burns service with an aggressive wound care protocol involving debridement of blistered epidermis and wound closure with synthetic and biological dressings seems to have produced benefits in mortality when compared to predicted outcomes.

The Jose f Gallery, located in the central Bohemia region of the Czech Republic (not far from the capital, Prague), was first excavated in 1981 as an exploration complex for the potential mining of gold. In 2007, the gallery was substantially reconstructed to house the Jose f Underground Educational Facility (Jose f UEF), which subsequently became an autonomous workplace under the direction of the Czech Technical University in Prague. At the beginning of 2010, the UEF was renamed the Jose f Regional Underground Research Centre (Jose f URC) which, along with the extensive underground complex, features modern above-ground facilities. One of the most important roles of this research centre is to provide practical -in situ- instruction in the fields of geotechnical engineering, geology, geochemistry, radiochemistry and radioecology. The training of future experts in this authentic underground setting involves the participation of several other Czech universities and numerous experienced specialists from outside the academic sphere. The IAEA has recently added the Jose f URC to its prestigious list of international training centres involved in the Training in and demonstration of waste disposal technologies in underground research facilities - A network of centres of excellence project.

We evaluated lymphotropic nanoparticle enhanced magnetic resonance imaging (LNMRI) with ferumoxtran-10 in determining the presence of regional lymph node metastases in patients with penile cancer. Seven patients with squamous cell carcinoma of the penis underwent LNMRI. All patients subsequently underwent groin dissection and the nodal images were correlated with histology. We found that LNMRI had sensitivity, specificity, and positive and negative predictive values of 100%, 97%, 81.2% and 100%, respectively, in predicting the presence of regional lymph node metastases in patients with penile cancer. Lymph node scanning using LNMRI accurately predicts the pathological status of regional lymph nodes in patients with cancer of the penis. LNMRI may accurately triage patients for regional lymphadenectomy.

In Switzerland, prostate cancer mortality is higher in the German than in the Italian-speaking region. We aimed at exploring the association of living in one of the two regions with lifestyle factors presumably lowering the risk of prostate cancer. We pooled data from the Swiss Health Survey, conducted every 5 years 1992 - 2012. Information on diet (meat, fish, dairy, fruits and vegetables), alcohol, smoking, physical activity and body mass index were dichotomized into "risky" and "risk-reducing" lifestyle behaviour with respect to prostate cancer. Multivariable logistic regression analyses were performed to assess associations between the German and Italian region of Switzerland and each single lifestyle factor. Living in the Italian region was associated with "risk-reducing" diet, i.e. with a higher prevalence of low dairy products and meat consumption and high fish consumption (odds ratio [OR] 1.34, 95% confidence interval [CI] 1.21 - 1.48; OR 3.31, 95% CI 2.94 - 3.72; OR 1.90, 95% CI 1.71 - 2.12, respectively). However, men in the Italian region were less likely to have low alcohol consumption and regular physical activity than men in the German region (OR 0.43, 95% CI 0.36 - 0.52 and OR 0.77, 95% CI 0.69 - 0.86, respectively). Prostate cancer risk-reducing dietary behaviour (i.e., less dairy products, less meat and more fish) was more common in the Italian region, whereas other risk-reducing lifestyle behaviours were more common in the German region.

Roche and IAEA announce joint initiative to train healthcare workers for Africa's fight against cancer. EDUCARE partnership to launch IAEA's VUCCnet training networks

International Nuclear Information System (INIS)

2010-01-01

Full text: Roche and the International Atomic Energy Agency (IAEA) announced today the launch of the EDUCARE (EDUcation for Cancer in African REgions) project to provide concerted support to help combat the growing cancer epidemic in sub-Saharan Africa. The EDUCARE project is to be piloted in Ghana, Tanzania, Uganda and Zambia, and is linked with the IAEA's wider initiative to build regional training networks in cancer control and a Virtual University for Cancer Control (VUCCnet) in Africa. A core component for the successful fight against cancer in any country is the education and training of health care providers. The VUCCnet will allow for training to be provided in an integrated and sustainable way in Africa by taking advantage of low-cost online learning tools. The IAEA is working in collaboration with the World Health Organization (WHO) and other international partners to develop the VUCCnet across Africa. The EDCUARE project will facilitate a first-of-its-kind exchange of knowledge and skills, both at the healthcare provider and country-wide level. Training will be provided by an on-line training resource centre, known as the Virtual University for Cancer Control (VUCC), the first such platform for health workers across the continent. Maturin Tchoumi, General Manager Roche South Africa said: 'As a leader in oncology, Roche believes that its strengths, expertise and resources can be used to improve the quality of oncology training and education in the poorest countries in the world. There is a real lack of basic education in oncology in Africa. By contributing our skills and competencies on the ground, Roche can make a real and sustainable improvement.' This new public-private partnership reflects a shared concern over the increasing cancer burden in sub-Saharan Africa, a region of the world where cancer rates are growing rapidly. Cancer now accounts for 12.5% of all deaths worldwide, more than HIV/AIDS, TB and malaria combined. By 2020, there are expected to

Colorectal Cancer Genetic Heterogeneity Delineated by Multi-Region Sequencing.

Full Text Available Intratumor heterogeneity (ITH leads to an underestimation of the mutational landscape portrayed by a single needle biopsy and consequently affects treatment precision. The extent of colorectal cancer (CRC genetic ITH is not well understood in Chinese patients. Thus, we conducted deep sequencing by using the OncoGxOne™ Plus panel, targeting 333 cancer-specific genes in multi-region biopsies of primary and liver metastatic tumors from three Chinese CRC patients. We determined that the extent of ITH varied among the three cases. On average, 65% of all the mutations detected were common within individual tumors. KMT2C aberrations and the NCOR1 mutation were the only ubiquitous events. Subsequent phylogenetic analysis showed that the tumors evolved in a branched manner. Comparison of the primary and metastatic tumors revealed that PPP2R1A (E370X, SETD2 (I1608V, SMAD4 (G382T, and AR splicing site mutations may be specific to liver metastatic cancer. These mutations might contribute to the initiation and progression of distant metastasis. Collectively, our analysis identified a substantial level of genetic ITH in CRC, which should be considered for personalized therapeutic strategies.

The lower risk of cancer in the areas inhabited by the German minority in the region of Opole, Poland, at the turn of the 1980's and 1990's has been already reported. A reanalysis of the present-day data was conducted. All the cancer cases (at all sites combined) registered within the years 2008-2012 with data collected by the Regional Cancer Registry in Opole were analyzed in this study. To estimate the risk of cancer in different spatial contexts, such as trends, clusters, and levels, modern geostatistical tools were applied. A statistically significant reduction of the cancer risk was reported in administrative units with ≥ 10% of the German minority. Average decreases in relative risk of 13% in men and 16% in women were estimated. The geographical patterns of the estimates are illustrated. The observed differences in the risk of cancer between the ethnic groups (Germans and repatriates) confirm a historical trend of the disease in the region of Opole, Poland. Some genetic, nutritional, or cultural aspects together with economic issues may play a role in the specified spatial disease patterns. © 2015 S. Karger GmbH, Freiburg.

Vagane, Randi; Danielsen, Turi; Fossa, Sophie Dorothea; Lokkevik, Erik; Olsen, Dag Rune

2009-01-01

Background and purpose: To investigate density changes in lung tissue, 3-4 years after postoperative adjuvant radiotherapy for breast cancer, based on dose dependence and regional differences. Material and methods: Sixty-one breast cancer patients, who had received computed tomography (CT) based postoperative radiotherapy, were included. CT scans were performed 35-51 months after start of radiotherapy. Dose information and CT scans from before and after radiotherapy were geometrically aligned in order to analyse changes in air-filled fraction (derived from CT density) as a function of dose for different regions of the lung. Results: Dose-dependent reduction of the air-filled fraction was shown to vary between the different regions of the lung. For lung tissue receiving about 50 Gy, the largest reduction in air-filled fraction was found in the cranial part of the lung. An increased air-filled fraction was observed for lung tissue irradiated to doses below 20 Gy, indicating compensatory response. Conclusions: The treatment-induced change in whole-lung density is a weighted response, involving the different regions, the irradiated volumes, and dose levels to these volumes. Simplistic models may therefore not be appropriate for describing the whole-lung dose-volume-response relationship following inhomogeneous irradiation

Cancer represents a major health burden and drain on healthcare resources in the world. The majority of the people of Africa still patronize traditional medicine for their health needs, including various forms of cancer. The aim of the following study is the identification of medicinal plants used for cancer treatment by the traditional healers in the Ashanti area of Ghana and to cross-reference the identified plant species with published scientific literature. Validated questionnaires were administered to 85 traditional healers in 10 communities within Ashanti region. For cross-validation, also 7 healers located outside Ashanti region were investigated to evaluate regional differences. Interviews and structured conversations were used to administer the questionnaires. Selected herbal material dominantly used by the healers was collected and identified. The ethnopharmacological survey revealed 151 plant species used for cancer treatment. Identified species were classified into different groups according to their frequency of use, resulting in the "top-22" plants. Interestingly group I (very frequent use) contained 5 plant species (Khaya senegalensis, Triplochiton scleroxylon, Azadirachta indica, Entandrophragma angolense, Terminalia superba), three of which belong to the plant family Meliaceae, phytochemically mainly characterized by the presence of limonoids. Cross-referencing of all plants identified by current scientific literature revealed species which have not been documented for cancer therapy until now. Special interest was laid on use of plants for cancer treatment of children. A variety of traditionally used anti-cancer plants from Ghana have been identified and the widespread use within ethnotraditional medicine is obvious. Further in vitro and clinical studies will be performed in the near future to rationalize the phytochemical and functional scientific background of the respective extracts for cancer treatment.

Today it is well-known that high risk of genetic breast cancer concerns a very limited part of the population: no more than 2-3 women are affected every thousand and this condition as a whole accounts for no more than 3%-5% of all breast cancers. Following the directions contained in the 2014-2018 National Prevention Plan, Veneto's 2014-2018 Regional Program of Prevention (PRP), approved by Regional Council Resolution (DGR) No. 749 of 14.5.2015, consolidation of a pathway of diagnosis, observation, and prophylaxis for women at high risk of hereditary breast carcinoma is thus proposed. The principal activities of this policy will be the following: creation of a regional working group, survey of currently existing pathways for the identification of women at risk of hereditary breast cancer and adoption of the same, approval and consolidation of a structured regional pathway for women at high risk of hereditary breast and/or ovarian cancer, from paths of oncogenetic consultation and genetic testing to management of disease risk. Subsequent to the recognition of the pathway of diagnosis, observation, and prophylaxis for women at high risk of hereditary breast carcinoma, the Veneto region undertakes to develop a co-ordinated program of information and training on this pathway directed at the population and healthcare workers. It is firmly hoped that with the inclusion of a program for the management of women at high risk of hereditary breast cancer within the Veneto PRP this topic may become more defined and structured in terms of sustainability, integration with the existing regional networks (mammography network, Breast Unit), contrasting inequality, monitoring and evaluation, in this way pursuing the objectives of a reduction of cause-specific mortality and improvement of quality of life.

Regional trends in breast cancer incidence and mortality in Denmark prior to mammographic screening

DEFF Research Database (Denmark)

Andreasen, A H; Andersen, K W; Madsen, Mette

1994-01-01

To provide a basis for the evaluation of mammographic screening programmes in Denmark, a study was undertaken of the regional differences in breast cancer incidence and mortality. All 16 regions were followed for the 20 year period, 1970-89, before the start of the first population...... among women below age 60. The mortality was more stable, changing only from 24 to 28 (per 100,000 standardised WSP), but a significant increase occurred in the late 1980s. The study showed regional differences in both incidence and mortality of breast cancer in Denmark. Both the incidence......-based mammographic screening programme in the Copenhagen municipality in 1991. Multiplicative Poisson models were used for the analysis. In general, the incidence increased during this period from 55 to 70 [per 100,000 standardised world standard population (WSP)], and the analysis shows this to be most pronounced...

The purpose of this study is to analyze the causes of Loco-regional failure in 51 patients with tumors of the oral cavity abutting the mandible. Patients and Methods: This cross-sectional study (27 patients were operated upon in the retrospective section and 24 patients in the prospective section of the study) was done in the department of Surgical Oncology, National Cancer Institute, Cairo University, from January 2003 to January 2008. Fifty-one patients, with oral cavity cancerous lesions abutting the mandible, were operated upon by segmental mandibulectomy en-bloc with primary tumor resection in addition to modified radical or selective neck dissection according to the status of the cervical lymph nodes. Results: During a median follow-up of 2 years, 29 patients (56.8%) had local recurrences, the incidence of nodal recurrence after neck dissection was detected in 4 patients (7.8%). On multivariate analysis, tumor depth, tumor grade, oral mucosa, soft tissue and bone surgical margins in addition to metastatic lymphadenopathy were independent prognostic factors of loco-regional failure and disease-free survival. Conclusion: Oral cavity cancers abutting the mandible should be treated with great caution by a multidisciplinary oncology team (resection and reconstruction surgeons) as it has a very aggressive biologic behavior. Negative intraoperative pathological margins should be attempted since this is the critical point for patients with cancers abutting the mandible? Further research on the biologic margin and genetic study is required

Breast cancer (BC) is the most frequent tumour affecting women all over the world. In low- and middle-income countries, where its incidence is expected to rise further, BC seems set to become a public health emergency. The aim of the present study is to provide a systematic review of current BC screening programmes in WHO European Region to identify possible patterns. Multiple correspondence analysis was performed to evaluate the association among: measures of occurrence; GNI level; type of BC screening programme; organization of public information and awareness campaigns regarding primary prevention of modifiable risk factors; type of BC screening services; year of screening institution; screening coverage and data quality. A key difference between High Income (HI) and Low and Middle Income (LMI) States, emerging from the present data, is that in the former screening programmes are well organized, with approved screening centres, the presence of mobile units to increase coverage, the offer of screening tests free of charge; the fairly high quality of occurrence data based on high-quality sources, and the adoption of accurate methods to estimate incidence and mortality. In conclusion, the governments of LMI countries should allocate sufficient resources to increase screening participation and they should improve the accuracy of incidence and mortality rates.

This letter addresses a technical question in connection with the recent paper by Knox et al. In particular, it concerns a correction to the estimate of childhood cancer risk following obstetric radiography, based on the Oxford Survey of Childhood Cancers (OSCC). One of us (CRM) enquired about the centring values for variables used in the analysis and particularly about the formulae used to calculate the higher order interactions of the radiation risk with birth year and age at diagnosis. These centring values and formulae are given in Table 1. This letter arises from that enquiry. (author).

Full Text Available Introduction: Typhoon Haiyan caused thousands of deaths and catastrophic destruction, leaving many homeless in Region 8 of the Philippines. A team from the Philippine Field Epidemiology Training Program conducted a rapid health assessment survey of evacuation centres severely affected by Haiyan. Methods: A descriptive study was conducted whereby a convenience sample of evacuation centres were assessed on the number of toilets per evacuee, sanitation, drinking-water, food supply source and medical services. Results: Of the 20 evacuation centres assessed, none had a designated manager. Most were located in schools (70% with the estimated number of evacuees ranging from 15 to 5000 per centre. Only four (20% met the World Health Organization standard for number of toilets per evacuee; none of the large evacuation centres had even half the recommended number of toilets. All of the evacuation centres had available drinking-water. None of the evacuation centres had garbage collection, vector control activities or standby medical teams. Fourteen (70% evacuation centres had onsite vaccination activities for measles, tetanus and polio virus. Many evacuation centres were overcrowded. Conclusion: Evacuation centres are needed in almost every disaster. They should be safely located and equipped with the required amenities. In disaster-prone areas such as the Philippines, schools and community centres should not be designated as evacuation centres unless they are equipped with adequate sanitation services.

Burden of cervical cancer (CC) is highest for women in low- and middle-income countries (LMICs). Human papillomavirus (HPV) is implicated as the necessary cause of CC although a number of other factors aid the long process of CC development. One among them is the presence of reproductive tract infections (RTIs). This study investigated the associations between RTIs and CC from India. This study utilized secondary data from the Cancer Detection Centre of the ICS, Delhi. Data were accessed from MS access database and were analyzed using MS Excel and SPSS 16.0. Multivariate analysis using unconditional logistic regression produced odds ratios (ORs) and 95 % confidence intervals (CIs). This study used data from 11,427 women over a period of 2000-2012. Women with RTIs had Candida, Trichomonas vaginalis (TV) or coccoid infections with all having similar prevalence (~4-5 %). 9.4 % of women had premalignant lesions of cervix; ASCUS was most common (7.9 %) followed by LSIL (1.3 %). TV was significantly associated with ASCUS, LSIL and all premalignant lesions of cervix (P Lack of awareness and hygiene, and limited access to gynecologists in LMICs lead to frequent and persistent RTIs which aid and abet HPV infection and CC occurrence. These also need to be addressed to reduce CC and RTIs among women in LMICs.

Head and neck cancer treatment affects quality of life. There are differences in quality of life outcomes and perceived supportive care needs between cancer patients living in metropolitan and regional-remote areas. This study investigated quality of life over the first 6 months following head and neck cancer diagnosis and observed differences in quality of life by geographical location. Prospective observational study. Tertiary hospital in Brisbane, Australia. Newly diagnosed patients who were referred for the diagnosis, and/or treatment of head and neck cancer. Quality of life was measured by the University of Washington Quality of Life Survey, version 4 (UW-QoL). Participants completed the UW-QoL questionnaire prior to starting treatment, 1 month and 6 months post treatment. Metropolitan and regional or remote status was classified according to the Australian Standard Geographic Classification-Remoteness Area system. Ninety-five participants were included at baseline; 49 and 41 participants completed the 1-month and 6-month follow-ups, respectively. Scores in most UW-QoL domains decreased between baseline and 1 month post treatment and increased towards pre-treatment scores at the 6-month follow-up (except for anxiety and saliva). Pain at baseline was significantly worse in the regional-remote participants compared with metropolitan participants. No other statistically significant differences in UW-QoL score by geographical location were observed. The findings generally did not support significant differences in quality of life outcome between metropolitan and regional-remote head and neck cancer patients. The difference in pain experience between metropolitan and regional-remote groups requires further investigation. © 2018 National Rural Health Alliance Ltd.

Transanal endoscopic microsurgery (TEMS) is becoming more widespread due to the increasing body of evidence to support its role. Previous published data has reported recurrence rates in excess of 10% for benign polyps after TEMS. Bradford Royal Infirmary is a tertiary referral centre for TEMS and early rectal cancer in the UK. Data for all TEMS operations were entered into a prospective database over a 7-year period. Demographic data, complications and recurrence rates were recorded. Both benign adenomas and malignant lesions were included. A total of 164 patients (65% male), with a mean age of 68 years were included; 114 (70%) of the lesions resected were benign adenomas, and 50 (30%) were malignant lesions. Median polyp size was 4 (range 0.6-14.5) cm. Mean length of operation was 55 (range 10-120) min. There were no recurrences in any patients with a benign adenoma resected; two patients with malignant lesions developed recurrences. Three intra-operative complications were recorded, two rectal perforations (repaired primarily, one requiring defunctioning stoma), and a further patient suffered a blood loss of >300 ml requiring transfusion. Six patients developed strictures requiring dilation either endoscopically or under anaesthetic in the post-operative period. We have demonstrated that TEMS procedures performed in a specialist centre provide low rates of both recurrence and complication. Within a specialist centre, TEMS surgery should be offered to all patients for rectal lesions, both benign and malignant, that are amenable to TEMS.

Background and purpose: PARSPORT was a multi-centre randomised trial in the UK which compared Intensity-Modulated Radiotherapy (IMRT) and conventional radiotherapy (CRT) for patients with head and neck cancer. The dosimetry audit goals were to verify the plan delivery in participating centres, ascertain what tolerances were suitable for head and neck IMRT trials and develop an IMRT credentialing program. Materials and methods: Centres enrolling patients underwent rigorous quality assurance before joining the trial. Following this each centre was visited for a dosimetry audit, which consisted of treatment planning system tests, fluence verification films, combined field films and dose point measurements. Results: Mean dose point measurements were made at six centres. For the primary planning target volume (PTV) the differences with the planned values for the IMRT and CRT arms were -0.6% (1.8% to -2.4%) and 0.7% (2.0% to -0.9%), respectively. Ninety-four percent of the IMRT fluence films for individual fields passed gamma criterion of 3%/3 mm and 75% of the films for combined fields passed gamma criterion 4%/3 mm (no significant difference between dynamic delivery and step and shoot delivery). Conclusions: This audit suggests that a 3% tolerance could be applied for PTV point doses. For dose distributions tolerances of 3%/3 mm on individual fields and 4%/3 mm for combined fields are proposed for multi-centre head and neck IMRT trials.

Comparison of cancer mortality in the Limousin and Poitou-Charentes regions (preliminary study 1968-1975)

The geology of the Limousin and Poitou-Charentes regions is very different; on an average, in the Limousin region, an inhabitant receives a supplementary dose of 65 mrem per year (terrestrial radiation) and the indoor radon concentration is 3-4 times higher than in the Poitou-Charentes region. The comparative rates of mortality for different types of malignant tumours (No. 20-27 of the INSERM DM list) were studied for the period extending from the 1968 to the 1975 census and for all ages according to the 1968 reference population. No significant difference appeared for these different types of cancers, except for cancers of the digestive system, which require a more thorough study. The more surprising result concernes malignant tumours of the respiratory system for which no difference -even small- appears; tobacco consumption per inhabitant was practically the same, on an average, in both regions [fr

Laparoscopic complete mesocolic excision (CME) used in the treatment of transverse colon cancer has been questioned on the basis of the technical challenges. The aim of this study was to evaluate the medium- and long-term clinical and survival outcomes after laparoscopic and open CME for transverse colon cancer and to compare the 2 approaches. This study was a retrospective non-randomized study of patients with prospectively registered data on open and laparoscopic CME for transverse colon cancer tumour-node-metastasis stages I-III operated on between 2007 and 2014. This was a single-centre study in a community teaching hospital. A total of 56 patients with transverse colon cancer were included, excluding those with tumours in the colonic flexures. The outcome aims were 4-year time to recurrence (TTR) and cancer-specific survival (CSS). Morbidity was also measured. The 4-year TTR was 93.9% in the laparoscopic group and 91.3% in the open group (p = 0.71). The 4-year CSS was 97.0% in the laparoscopic group and 91.3% in the open group (p = 0.42). This was a prospective single-institution study with a small sample size. Results of the study suggest that the laparoscopic CME approach might be the preferred approach for transverse colon cancer, especially regarding its benefits in terms of short-term morbidity, length of stay and oncological outcome. © 2016 S.

this article presents a review of evidences about Human Papillomavirus (HPV) and cervical cancer in Italy, highlighting geographical differences. two systematic reviews recently published were updated, one collecting studies on the prevalence of HPV types in Italy in the general population and the other collecting prevalence of HPV types in cervical pathologic samples.The search was updated to 31.10.2010 and performed exclusively in MedLine and references in retrieved papers. the prevalence of HPV types has been related with the incidence of cervical cancer and the spread of Pap tests and screening programs. the prevalence high risk HPV types is 8%in studies with population-based random sample, with no significant difference between Centre-North and South-Islands, however, the prevalence is slightly higher in the South than the Centre-North for women up to 54 years of age, whereas in older women the ratio is reversed. HPV 16 is the most common type, while HPV 18 is less frequent, 5% and 1% respectively. The average of HPV 16 positivity is 64% and 68% in CIN2/3 and invasive cancer respectively, while the average of HPV 18 is 7% and 11% in CIN2/3 and invasive cancer respectively. There are no significant differences by geographical area.The incidence of invasive cervical cancer in Italy has been decreasing in recent years changing from 9.2 to 7.7 per 100,000 inhabitants in 10 years. The incidence is lower in South-Islands. Pap test coverage is over 80% in Centre-North and less than 60%in South-Islands. cervical cancer incidence is lower in Southern Italy, while the Pap test coverage is much higher in Centre-Northern Italy. This paradox, until now, has been interpreted as a consequence of a lower HPV prevalence in Southern than Northern regions. Recent studies on HPV prevalence do not confirm this hypothesis. Our interpretation is that in Southern Italy we are facing an epidemiologic scenario in transition where the low cancer incidence is the consequence of a low HPV

Lung cancer is the most frequently fatal cancer, with poor survival once the disease is advanced. Annual low-dose computed tomography has shown a survival benefit in screening individuals at high risk for lung cancer. Based on the available evidence, the European Society of Radiology and the European Respiratory Society recommend lung cancer screening in comprehensive, quality-assured, longitudinal programmes within a clinical trial or in routine clinical practice at certified multidisciplinary medical centres. Minimum requirements include: standardised operating procedures for low-dose image acquisition, computer-assisted nodule evaluation, and positive screening results and their management; inclusion/exclusion criteria; expectation management; and smoking cessation programmes. Further refinements are recommended to increase quality, outcome and cost-effectiveness of lung cancer screening: inclusion of risk models, reduction of effective radiation dose, computer-assisted volumetric measurements and assessment of comorbidities (chronic obstructive pulmonary disease and vascular calcification). All these requirements should be adjusted to the regional infrastructure and healthcare system, in order to exactly define eligibility using a risk model, nodule management and a quality assurance plan. The establishment of a central registry, including a biobank and an image bank, and preferably on a European level, is strongly encouraged. (orig.)

It is well known that socio-economic status is a strong predictor of screening attendance, with women of higher socioeconomic status more likely to attend breast cancer screening. We investigated whether socio-economic status was related to the detection of cancer at breast screening centres. In two separate projects we combined UK data from the population census, the screening information systems, and the cancer registry. Five years of data from all 81 screening centres in the UK was collected. Only women who had previously attended screening were included. The study was given ethical approval by the University of Warwick Biomedical Research Ethics committee reference SDR-232-07- 2012. Generalised linear models with a log-normal link function were fitted to investigate the relationship between predictors and the age corrected cancer detection rate at each centre. We found that screening centres serving areas with lower average socio-economic status had lower cancer detection rates, even after correcting for the age distribution of the population. This may be because there may be a correlation between higher socio-economic status and some risk factors for breast cancer such as nullparity (never bearing children). When applying adjustment for age, ethnicity and socioeconomic status of the population screened (rather than simply age) we found that SDR can change by up to 0.11.

To describe our experience with cisplatin- and paclitaxel-based IP chemotherapy in patients treated initially with either neoadjuvant chemotherapy and interval debulking surgery (IDS) or primary cytoreductive surgery (PCRS). We performed a retrospective review of the records of 67 patients (38 IDS, 29 PCRS) enrolled in the intraperitoneal (IP) chemotherapy program at the Tom Baker Cancer Centre between 2006 and 2009. Information pertaining to patient demographics, IP chemotherapy toxicity, and catheter complications was extracted, and the median time to recurrence was calculated. Most patients in the study were aged 50 to 70 years and had a diagnosis of stage III serous ovarian cancer. Overall, 295/393 IP cycles (75%) were successfully administered. The proportion of patients completing six cycles of chemotherapy in the IDS and PCRS groups was 53% and 59%, respectively. Frequent (> 25%) Grade 1 to 2 chemotherapy toxicities included fatigue, peripheral neuropathy, and nausea. Catheter complications were observed in 34% of patients (23/67). The recurrence rates for patients completing four or more cycles of IP chemotherapy in the IDS and PCRS groups were 58% and 35%, respectively, with the median time to recurrence approximately one year. Although IP chemotherapy is well tolerated in both IDS and PCRS patients, the median time to recurrence is shorter than expected.

The purpose of the study was to examine differences in rates of appropriate breast cancer screening (i.e., screening mammography every 2 years) among Ontario immigrant women by world region of origin and explore the association between appropriate breast cancer screening among these women groups and individual and structural factors. A cohort of 183,332 screening-eligible immigrant women living in Ontario between 2010 and 2012 was created from linked databases and classified into eight world regions of origin. Appropriate screening rates were calculated for each region by age group and selected sociodemographic, immigration, and healthcare-related characteristics. The association between appropriate screening across the eight regions of origin and selected sociodemographic, immigration, and health-related characteristics was explored using multivariate Poisson regression. Screening varied by region of origin, with South Asian women (48.5%) having the lowest and Caribbean and Latin American women (63.7%) the highest cancer screening rates. Factors significantly associated with lower screening across the world regions of origin included living in the lowest income neighborhoods, having a refugee status, being a new immigrant, not having a regular physical examination, not being enrolled in a primary care patient enrollment model, having a male physician, and having an internationally trained physician. Multiple interventions entailing cross-sector collaboration, promotion of patient enrollment models, community engagement, comprehensive and intensive outreach to women, and knowledge translation and transfer to physicians should be considered to address screening disparities among immigrant population. Consideration should be given to design and delivery of culturally appropriate and easily accessible cancer screening programs

Full Text Available Oral cancer is the eighth most common cancer worldwide and presents a serious health problem in countries with higher alcohol consumption and smoking. The aim of the present study was to analyze the survival rates of patients with oral cancer diagnosed at a single center in Bulgaria. The clinical records of patients with oral cancer admitted to the Clinic of Maxillofacial surgery, University Hospital “St. George”, Plovdiv, Bulgaria, from 2004 till 2013 were reviewed. Additional information about follow-up was obtained from the Regional Complex Oncological Centre (RCOC. Data about patient and tumor characteristics – age, sex, site of cancer, stage, degree of differentiation and survival rates were analyzed. The overall 5-year survival rate was 36% while the disease-specific survival rate was 45%. The highest chance for survival was for upper lip (66% while the lowest was for retromolar trigone (0%. Overall survival rate depended also on the stage and grade of differentiation of the tumor. The study confirmed that oral cancer remains serious problem in terms of risk factors, delayed diagnosis, and overall survival rates.

Full Text Available AKT is a signal transduction protein that plays a central role in the tumorigenesis. There are 3 mammalian isoforms of this serine/threonine protein kinase-AKT1, AKT2, and AKT3-showing a broad tissue distribution. We first discovered 2 novel polymorphisms (AKT2 -9826 C/G and AKT3 -811 A/G, and we confirmed 6 known polymorphisms (AKT2 -9473 C/T, AKT2 -9151 C/T, AKT2 -9025 C/T, AKT2 -8618G/A, AKT3 -675 A/-, and AKT3 -244 C/T of the AKT2 and AKT3 promoter region in 24 blood samples of Korean lung cancer patients using direct sequencing. To evaluate the role of AKT2 and AKT3 polymorphisms in the risk of Korean lung cancer, genotypes of the AKT2 and AKT3 polymorphisms (AKT2 -9826 C/G, AKT2 -9473 C/T, AKT2 -9151 C/T, AKT2 -9025 C/T, AKT2 -8618G/A, and AKT3 -675 A/- were determined in 360 lung cancer patients and 360 normal controls. Statistical analyses revealed that the genotypes and haplotypes in the AKT2 and AKT3 promoter regions were not significantly associated with the risk of lung cancer in the Korean population. These results suggest that polymorphisms of the AKT2 and AKT3 promoter regions do not contribute to the genetic susceptibility to lung cancer in the Korean population.

B lymphoma Moloney murine leukemia virus insertion region 1 (BMI1), a core member of polycomb repressive complex 1 (PRC1), has been intensely investigated in the field of cancer epigenetics for decades. Widely known as a critical regulator in cellular physiology, BMI1 is essential in self-renewal and differentiation in different lineages of stem cells. BMI1 also plays a significant role in cancer etiology for its involvement in pathological progress such as epithelial-mesenchymal transition (EMT) and cancer stem cell maintenance, propagation, and differentiation. Importantly, overexpression of BMI1 is predictive for drug resistance, tumor recurrence, and eventual therapy failure of various cancer subtypes, which renders the pharmacological targeting at BMI1 as a novel and promising therapeutic approach. The study on prostate cancer, a prevalent hormone-related cancer among men, has promoted enormous research advancements in cancer genetics and epigenetics. This review summarizes the role of BMI1 as an oncogenic and epigenetic regulator in tumor initiation, progression, and relapse of prostate cancer.

During cancer progression, specific genomic aberrations arise that can determine the scope of the disease and can be used as predictive or prognostic markers. The detection of specific gene amplifications or deletions in single blood-borne or disseminated tumour cells that may give rise to the development of metastases is of great clinical interest but technically challenging. In this study, we present a method for quantitative high-resolution genomic analysis of single cells. Cells were isolated under permanent microscopic control followed by high-fidelity whole genome amplification and subsequent analyses by fine tiling array-CGH and qPCR. The assay was applied to single breast cancer cells to analyze the chromosomal region centred by the therapeutical relevant EGFR gene. This method allows precise quantitative analysis of copy number variations in single cell diagnostics.

As developments in cancer treatment have improved outcomes, research has increasingly focused on the role of cancer-related cognitive impairment (CRCI) in quality of life for cancer survivors. Impairment profiles have been heterogeneous across studies, necessitating the study of these effects across different cohorts. The purpose of this preliminary study is to compare the memory profiles of Northeast Ontario breast and CNS cancer patients, as there is no literature which exists for profiling CRCI within this largely rural region. Sixty-three outpatients with breast cancer (n = 32) or CNS tumors (n = 30) at the Northeast Cancer Centre in Sudbury, Canada, were administered a neuropsychological test battery as part of their clinical examination. Domains measured within this study included attention and concentration, processing speed, motor function, language skills, verbal and visual memory, and executive functioning. Participants with brain tumors scored poorer on most neuropsychological measures than participants with breast cancer. Initial verbal memory for individuals with breast cancer was lower than delayed recall and recognition trials. Trial 1 performance for this group was also negatively correlated with self-reported anxiety scores. Consistent with the literature, participants with breast cancer obtained higher scores on most test measures than participants with CNC tumors. Breast cancer participants had lower verbal memory scores on initial trials compared to delayed recall, potentially due to relationships with anxiety and attention. Further research into this cohort will strive to gain greater understanding of the patterns of deficits experienced and how these may inform individuals with cancer in other regions.

Purpose: To report the results of using contact X-ray (CXR), which has been used in the Centre-Lacassagne since 2002 for rectal cancer. Methods and Materials: A total of 44 patients were treated between 2002 and 2006 using four distinct clinical approaches. Patients with Stage T1N0 tumors were treated with transanal local excision (TLE) and adjuvant CXR (45 Gy in three fractions) (n = 7). The 11 inoperable (or who had refused surgery) patients with Stage T2-T3 disease were treated with CXR plus external beam radiotherapy (EBRT). Those with Stage T3N0-N2 tumors were treated with preoperative CXR plus EBRT (with or without concurrent chemotherapy) followed by surgery (n = 21). Finally, the patients with Stage T2 disease were treated with CXR plus EBRT followed by TLE (n = 5). Results: The median follow-up was 25 months. In the 7 patients who underwent TLE first, no local failure was observed, and their anorectal function was good. Of the 11 inoperable patients who underwent CXR plus EBRT alone, 10 achieved local control. In the third group (preoperative CXR plus EBRT), anterior resection was performed in 16 of 21 patients. Complete sterilization of the operative specimen was seen in 4 cases (19%). No local recurrence occurred. Finally, of the 5 patients treated with CXR plus EBRT followed by TLE, a complete or near complete clinical response was observed in all. TLE with a R0 resection margin was performed in all cases. The rectum was preserved with good function in all 5 patients. Conclusion: These early results have confirmed that CXR combined with surgery (or alone with EBRT) can play a major role in the conservative and curative treatment of rectal cancer

Globally, cancer is one of the leading causes of mortality. High treatment cost, partly owing to higher prices of anti-cancer drugs, presents a significant burden on patients and healthcare systems. The aim of the present study was to survey and compare retail prices of anti-cancer drugs between high, middle and low income countries in the South-East Asia, Western Pacific and Eastern Mediterranean regions. Cross-sectional survey design was used for the present study. Pricing data from ten counties including one from South-East Asia, two from Western Pacific and seven from Eastern Mediterranean regions were used in this study. Purchasing power parity (PPP)-adjusted mean unit prices for 26 anti-cancer drug presentations (similar pharmaceutical form, strength, and pack size) were used to compare prices of anti-cancer drugs across three regions. A structured form was used to extract relevant data. Data were entered and analysed using Microsoft Excel®. Overall, Taiwan had the lowest mean unit prices while Oman had the highest prices. Six (23.1%) and nine (34.6%) drug presentations had a mean unit price below US$100 and between US$100 and US$500 respectively. Eight drug presentations (30.7%) had a mean unit price of more than US$1000 including cabazitaxel with a mean unit price of $17,304.9/vial. There was a direct relationship between income category of the countries and their mean unit price; low-income countries had lower mean unit prices. The average PPP-adjusted unit prices for countries based on their income level were as follows: low middle-income countries (LMICs): US$814.07; high middle income countries (HMICs): US$1150.63; and high income countries (HICs): US$1148.19. There is a great variation in pricing of anticancer drugs in selected countires and within their respective regions. These findings will allow policy makers to compare prices of anti-cancer agents with neighbouring countries and develop policies to ensure accessibility and affordability of

Objective: To explore the clinical value of duralphase enhanced electronic beam computed tomography (EBCT) scans in resectability evaluation of lung cancer located in hilar region. Methods: Dual phase enhanced EBCT scans were available for 40 cases that were initially diagnosed as 'carcinoma of lung' in hilar region. The relations between masses and trachea, bronchi, hilar and mediastinal great vessels were analyzed and compared with operation. Results: 38 cases in our series confirmed by operation and pathological examination were divided two groups: respectable (28 cases) and non-resectable (10 cases) groups. 25 cases in the former group were consistent with operation, accounting for 89.3%, and 8 cases, in the latter group, accounting for 80%. The sensitivity, specificity and accuracy of dural-phase enhanced EBCT scan evaluating the relations between masses and hilar and mediastinal structure were as follows: 92.6%, 72.7% and 86.8%. Conclusion: Dural-phase enhanced EBCT scans can provide precise and feasible pre-operative evaluation of lung cancer in hilar region. (authors)

Hong, Mark

It is clear that a lot of work needs to be done to increase understanding within the region about Confidence Building Measures (CBMs) and the promotion of regional exchanges of information. A graduated and slow approach would be needed to overcome the existing suspicions and wariness about these new concepts. I have mentioned that the 'two tracks', which are complementary, would probably constitute a practical approach. The CSCAP series is particularly useful and important among the track-two discussions. In addition, I have identified some practical areas where the Kathmandu Centre could concentrate its work, such as organizing workshops to increase awareness and knowledge of such ongoing CBMs as the United Nations Arms Register, CSCAP and the ASEAN Regional Forum. In addition, the Centre could perform the roles of depository of seminar papers, of being the electronic hub of a network connecting the regional think-tanks and-even more ambitious-of becoming a centre for studies in preventive diplomacy and regional security. All these efforts will help to slowly transform the regional security perceptions between Asian countries and provide a positive regional security atmosphere, one conducive to regional economic progress and cooperation

Despite the fact that cancer of the thyroid gland is a rare disease it has attracted a lot of attention. It is one of the few disease where radioactive isotopes are used not only for detection but also for treatment of the disease. The Radiation Medicine Centre (RMC) is the apex of all the departments of nuclear medicines in India. It was established in 1963 in the precincts of the Tata Memorial Hospital (TMH) which is the primer cancer centre of this country. This book is a collation of the combined experience of the TMH and the RMC. The objectives are two fold, viz. (1) an introspective analysis of our experience and (2) to offer a book of ready reference to anyone dealing with any aspect of thyroid cancer. Papers relevant to INIS are indexed separately

2017-01-01

The 1000s of people who die from cancer each year have become one of the leading causes of death among the Chilean population, placing it as the second cause of death in the region of Valparaiso between 1997 and 2003. Statistics have provided different measures regarding the life expectancy of cancer patients which have resulted in being useful to establish courses of action for prevention and treatment plans to follow. Data was extracted from the cancer module of the Epidemiology Assistance System (SADEPI for its initials in Spanish) which stores information about cancer cases in the provinces of Valparaiso and Petorca. The survival period is defined as the difference in days between the date of occurrence and the date of death of the patient by separating the data into quartiles. The more frequent cancers in the region of Valparaiso behave similarly to global behaviours of the disease. The majority of affected patients are around 65 years of age which progressively lowers its occurrence in younger adults under the age of 45. Further efforts are required for early detection and timely access to treatment for cancer patients. Statistics are an important support in achieving this.

To evaluate the financial burden of oesophageal cancer under the protection of the new Rural Cooperative Medical Scheme (NCMS) and to provide evidence and suggestions to policymakers in a high-incidence region in China. We analysed inpatient claim data for oesophageal cancer, gastric cancer and colorectal cancer from 1 January to 31 December 2013. The data were extracted from the NCMS management system of Hua County, Henan Province, a typical high-risk region for oesophageal cancer in China. Cancer-specific health economic indicators were calculated to evaluate the financial burden under the protection of the local NCMS. The total cost of oesophageal cancer was 2.7-3.6 times higher than that of gastric cancer and colorectal cancer, respectively, due to high incidence of oesophageal cancer. For each hospitalisation to treat oesophageal cancer, the average total cost and out-of-pocket expenses after reimbursement equalled an entire year's gross domestic product per capita and per capita disposable income, respectively, for the local area. The average total cost per hospitalisation for oesophageal cancer increased monotonically with hospital level for surgical hospitalisations, and it increased more rapidly for non-surgical hospitalisations (from $301 to $2589, 860%) than for gastric cancer (from $289 to $1453, 503%) and colorectal cancer (from $359 to $1610, 448%). Vulnerable groups with less access to high-level hospitals were found in different gender and age groups. Oesophageal cancer imposes serious financial burdens on communities and patients' households in this high-incidence region, and no preferential policy from the local NCMS has been designed to address this issue. A special supportive policy should be developed on the basis of local disease profiles and population characteristics to alleviate the financial burden of populations at high risk for certain high-cost diseases. © 2016 John Wiley & Sons Ltd.

This study reviews the presenting symptoms of colorectal cancer in the ethnically diverse Middlemore Hospital referral population of South Auckland, New Zealand. The performance of the newly introduced Auckland Regional Grading Criteria as prediction tool for selecting colorectal cancer cases referred from primary care was evaluated in this group. Retrospective review of all colorectal cancer (CRC) cases diagnosed between January 2006 and January 2011. Information extracted from case note review was used to grade patients using the Auckland Regional Grading Criteria. A total of 799 patients were included. The commonest symptoms were: rectal bleeding (25.5-42.3%) and change in bowel habit (20.6-26.8%). Low-risk symptoms including abdominal pain (16.3-46.8%) and weight loss (18.4-26.1%) were not uncommon. 64.4% of Maori and 64.9% of Pacific patients had stage III or IV cancers. Pacific patients had more stage IV disease, 37.7% (pAuckland Regional Grading Criteria would miss 24.7% of the patients with CRC in the referral population. While rectal bleeding and change in bowel habit are frequent presenting symptoms, low-risk atypical symptoms including constipation, weight loss and abdominal pain were not uncommon. Significant proportion of Pacific patients present with late-stage disease. The current Auckland Regional grading criteria would miss significant proportion of our study population with colorectal cancer.

Its main objective is the development of serviceable clinical practice guidelines in order to improve the quality of health care and the outcome of cancer patients. The methodology is based on a literature review, followed by a critical appraisal by a multidisciplinary group of experts. Draft guidelines are produced, then validated by specialists in cancer care delivery. Objectives. - Produce technical practice guidelines for the brachytherapy of prostate cancer using the methodology developed by the Standards, Options and Recommendations project. Methods. - The FNCLCC and the French Urology Association (AFU) first designated the multidisciplinary group of experts. Available data were collected by a search of Medline and lists selected by experts in the group. A first draft of the guidelines was written, they validated by independent reviewers. Results. - The main recommendations are: 1/ Brachytherapy with permanent seeds alone is a possible curative treatment for prostate cancer patients with the following prognosis factors: tumour stage T1 or T2a (TNM 1992), Gleason score ≤ 6 and PSA 7 and/or PSA > 10. 3/ Combination of brachytherapy and external beam radiation therapy can be proposed to prostate cancer patients with intermediate prognosis. 4/ Before and after seed implantation, risks of infection must be prevented by appropriate antibiotic therapy (recommendation). 5/ Brachytherapy must not be performed within 2 months of trans-urethral prostate resection. 6/The height of the urethra receiving more than 200 of the prescribed dose must be reported. The portion of the rectum receiving 100 and 120 % of the prescribed dose must be limited to 10

We have mapped the nearby flocculent spiral galaxy in the visible U, B and V bands, as well as in the near infrared J, H and K bands, with a linear resolution of 900 pc. The galaxy, which does not show marked spiral structure in visible photographs (Tammann and Sandage, 1968) nor in the 21 cm line of HI (Wevers, 1984) is found to have two principal current centres of large-scale star formation, signposted by centres of ultraviolet and blue flux. One is in the nucleus, defined by the geometrical centre of the HI emission, and the other at some 1.5 kpc radial distance away. The outer star-forming region is the more intense and the younger of the two, and corresponds to a local peak in the HI surface density. We use the colours of the star-forming regions and of the integrated galaxy to make a first order estimate of the stellar population distribution. (Author)

This study aims to determine if locoregional restaging with diagnostic mammography and ultrasound (US) of the whole breast and regional nodes performed for quality assurance in women with newly diagnosed breast cancer who were referred to a tertiary care center yields incremental cancer detection. An institutional review board-approved retrospective, single-institution database review was performed on the first 1000 women referred to our center in 2010 with a provisional breast cancer diagnosis. Locoregional restaging consisted of diagnostic full-field digital mammography combined with US of the whole breast and regional nodal basins. Bilateral whole-breast US was performed in women with contralateral mammographic abnormality or had heterogeneously or extremely dense parenchyma. Demographic, clinical, and pathologic factors were analyzed. Final analyses included 401 women. Of the 401 women, 138 (34%) did not have their outside images available for review upon referral. The median age was 54 years (range 21-92); the median tumor size was 2.9 cm (range 0.6-18.0) for women whose disease was upstaged and 2.2 cm (range 0.4-15.0) for women whose disease was not upstaged.

Full Text Available Background. Regional lymph node recurrence (RLNR is common in patients with thyroid cancer but clinicopathological predictors are unclear. We aimed to clarify these predictors and identify patients who would benefit from prophylactic lymph node dissection the most. Method. 343 patients with different types of thyroid cancer were analyzed retrospectively. All patients underwent total thyroidectomy between 2007 and 2013. Results. The median ± interquartile range of patients’ age was 40 ± 25 years. 245 (71.4% patients were female. Regarding the risk of regional lymph node recurrence, we found that male gender, age ≥45 years, non-PTC (i.e., medullary, follicular, and anaplastic types histopathology, T3 (i.e., tumor size >4 cm in the greatest dimension limited to the thyroid or any tumor with minimal extrathyroid extension, stage IVa, and isolated cervical lymphadenopathy as initial manifestation (ICL are significant risk factors. T3 (p < 0.001; odds ratio = 156.41, 95% CI [55.72–439.1] and ICL (p < 0.001; odds ratio = 77.79, 95% CI [31.55–191.81] were the strongest predictors of regional lymph node recurrence. Conclusion. We found easily achievable risk factors for RLNR in thyroid cancers patients. We suggested that patients with specific clinicopathological features like male gender, age ≥45 years, larger tumor size, and extrathyroidal extension be considered as prophylactic lymphadenectomy candidates.

In England in 2001 oesophagogastric cancer surgery was centralized. The aim of this study was to evaluate whether centralization of oesophagogastric cancer to high-volume centres has had an effect on mortality from different emergency upper gastrointestinal conditions. The Hospital Episode Statistics database was used to identify patients admitted to hospitals in England (1997-2012). The influence of oesophagogastric high-volume cancer centre status (20 or more resections per year) on 30- and 90-day mortality from oesophageal perforation, paraoesophageal hernia and perforated peptic ulcer was analysed. Over the study interval, 3707, 12 441 and 56 822 patients with oesophageal perforation, paraoesophageal hernia and perforated peptic ulcer respectively were included. There was a passive centralization to high-volume cancer centres for oesophageal perforation (26·9 per cent increase), paraoesophageal hernia (19·5 per cent increase) and perforated peptic ulcer (23·0 per cent increase). Management of oesophageal perforation in high-volume centres was associated with a reduction in 30-day (HR 0·58, 95 per cent c.i. 0·45 to 0·74) and 90-day (HR 0·62, 0·49 to 0·77) mortality. High-volume cancer centre status did not affect mortality from paraoesophageal hernia or perforated peptic ulcer. Annual emergency admission volume thresholds at which mortality improved were observed for oesophageal perforation (5 patients) and paraoesophageal hernia (11). Following centralization, the proportion of patients managed in high-volume cancer centres that reached this volume threshold was 88·0 per cent for oesophageal perforation, but only 30·3 per cent for paraoesophageal hernia. Centralization of low incidence conditions such as oesophageal perforation to high-volume cancer centres provides a greater level of expertise and ultimately reduces mortality. © 2017 BJS Society Ltd Published by John Wiley & Sons Ltd.

To provide an overview of the lung cancer incidence trends in the City of Zagreb (Zagreb), Split-Dalmatia County (SDC), and Croatia in the period from 2001 to 2013. Incidence data were obtained from the Croatian National Cancer Registry. For calculating incidence rates per 100 000 population, we used population estimates for the period 2001-2013 from the Croatian Bureau of Statistics. Age-standardized rates of lung cancer incidence were calculated by the direct standardization method using the European Standard Population. To describe incidence trends, we used joinpoint regression analysis. Joinpoint analysis showed a statistically significant decrease in lung cancer incidence in men in all regions, with an annual percentage change (APC) of -2.2% for Croatia, 1.9% for Zagreb, and -2.0% for SDC. In women, joinpoint analysis showed a statistically significant increase in the incidence for Croatia, with APC of 1.4%, a statistically significant increase of 1.0% for Zagreb, and no significant change in trend for SDC. In both genders, joinpoint analysis showed a significant decrease in age-standardized incidence rates of lung cancer, with APC of -1.3% for Croatia, -1.1% for Zagreb, and -1.6% for SDC. There was an increase in female lung cancer incidence rate and a decrease in male lung cancer incidence rate in Croatia in 2001-20013 period, with similar patterns observed in all the investigated regions. These results highlight the importance of smoking prevention and cessation policies, especially among women and young people.

Logit Model of Analysing the Factors Affecting the Adoption of Goat Raising Activity by Farmers in the Non-pastoral Centre Region of Cameroon

Directory of Open Access Journals (Sweden)

Folefack, AJZ.

2018-01-01

Full Text Available Three years after the beginning of a goat project in the Centre region of Cameroon, the engagement of farmers in this activity has been timid. As this region is not a traditional pastoral zone, farmers have not yet incorporated the crop-livestock integration into their habits. Hence, this paper uses a logistic regression approach in order to analyse the factors affecting the adoption of goat raising activity by farmers of this locality. The computed odds ratio indicate that the practice of goat raising activity is significantly influenced by the farmer's age, gender, farming experience, practice of other livestock activities, frequency of contact with extension agents, access to credit and farm income. However, being a goat raiser does not depend on the farmer's marital status, education, farm size, household size, membership into a common initiative group. The study therefore recommends that the government authorities should give more attention to significant factors so as to popularize the goat raising activity in this region.

The author presents considerations which should prove to be of interest to all those who have to design, to construct and to operate a nuclear research centre. A large number of the ideas presented can also be applied to non-nuclear scientific research centres. In his report the author reviews: various problems with which the constructor is faced: ground-plan, infrastructure, buildings and the large units of scientific equipment in the centre, and those problems facing the director: maintenance, production, supplies, security. The author stresses the relationship which ought to exist between the research workers and the management. With this aim in view he proposes the creation of National School for Administration in Research which would train administrative executives for public or private organisations; they would be specialised in the fields of fundamental or applied research.

2007-01-01

In 2004 the Department of Health in collaboration with Macmillan Cancer Support set up service development projects to pilot the integration of genetics in mainstream medicine in the area of cancer genetics.In developing these services, new roles and responsibilities were devised that required supporting programmes of education and training. The NHS National Genetics Education and Development Centre has worked with the projects to draw together their experience in these aspects. New roles include the Cancer Family Nurse Specialist, in which a nurse working in a cancer setting was trained to identify and manage genetic or family history concerns, and the Genetic Risk Assessment Practitioner--a small team of practitioners working within a secondary care setting to deliver a standardised risk assessment pathway. Existing roles were also adapted for a different setting, in particular the use of genetic counsellors working in a community ethnic minority setting. These practitioners undertook a range of clinical activities that can be mapped directly to the 'UK National Workforce Competences for Genetics in Clinical Practice for Non-genetics Healthcare Staff' framework developed by Skills for Health and the NHS National Genetics Education and Development Centre (2007; draft competence framework). The main differences between the various roles were in the ordering of genetic tests and the provision of advice on invasive preventive options such as mastectomy. Those involved in service development also needed to develop competences in project management, business skills, audit and evaluation, working with users, general management (personnel, multi-agency work and marketing), educational supervision, IT, public and professional outreach, and research. Important resources to support the development of new roles and competences included pathways and guidelines, a formal statement of competences, a recognised syllabus, appropriate and timely courses, the availability of a

Researchers, hospital administrators and governments are striving to define competencies in interprofessional care and education, as well as to identify effective models in chronic disease management. For more than 25 years The Arthritis Program (TAP) at Southlake Regional Health Centre in Newmarket, Ontario, has actively practiced within these two interrelated priorities, which are now at the top of the healthcare agenda in Ontario and Canada. The approximately 135 different rheumatic conditions are the primary cause of long-term disability in Canada, affecting those from youth to the senior years, with an economic burden estimated at $4.4 billion (CAD$) annually, and growing. For the benefit of healthcare managers and their clients with chronic conditions, this article discusses TAP's history and demonstrable success, predicated on an educational model of patient self-management and self-efficacy. Also outlined are TAP's contributions in supporting evidence-based best practices in interprofessional collaboration and chronic disease management; approaches that are arguably understudied and under-practiced. Next steps for TAP include a larger role in empirical research in chronic-disease management and integration of a formal training program to benefit health professionals launching or expanding their interprofessional programs using TAP as the dynamic clinical example.

2016-07-01

Data centres use a lot of power, consumed by two main usages: power required to run the actual equipment and power required to cool the equipment. Usage of electricity results in the production of electric and magnetic fields (EMF). Even though electricity is useful in human lives, there have been reported cases of adverse health effects from EMF generated from its use. Because the use of electricity is ubiquitous and plays a vital role in society’s economy, the possibility of harm from EMF to electric utility customers and workers deserves attention.The Electric and Magnetic fields for workers in data center in the Greater Accra Region have been assessed. The fundamental objective was to determine the levels of the electric and magnetic fields and to assess the extent of exposure of workers in the data centre to these fields. The results obtained for the electric field intensities in the data centre ranged from 6.03E-03 ± 7.54E-04 kVm"-"1 to 2.33E-04 ± 8.82E-05 kVm"-"1.The results obtained for the resultant field strength in the data centre ranged from 3.12E-01± 8.77E-03 μT to 6.57E-02 ± 7.38E-03 μT. The results obtained for the magnetic flux density ranged from 3.9E-07 ± 8.77E-03 μT to 7.27E-08 ± 7.31E-03 μT. The results obtained for the induced current density ranged from 2.37E-06 ± 1.50E-02 mA/m"2 to 2.46E-07 ± 9.99E-03 mA/m"2. Data obtained are below the basic restrictions for induced current density and reference levels for electric field and magnetic flux density set by the International. (au)

Full Text Available Cancers from lung and esophagus are the leading causes of cancer-related deaths in China and share many similarities in terms of histological type, risk factors and genetic variants. Recent genome-wide association studies (GWAS in Chinese esophageal cancer patients have demonstrated six high-risk candidate single nucleotide polymorphisms (SNPs. Thus, the present study aimed to determine the risk of these SNPs predisposing to lung cancer in Chinese population.A total of 1170 lung cancer patients and 1530 normal subjects were enrolled in this study from high-incidence areas for esophageal cancer in Henan, northern China. Five milliliters of blood were collected from all subjects for genotyping. Genotyping of 20 high-risk SNP loci identified from genome-wide association studies (GWAS on esophageal, lung and gastric cancers was performed using TaqMan allelic discrimination assays. Polymorphisms were examined for deviation from Hardy-Weinberg equilibrium (HWE using Х2 test. Bonferroni correction was performed to correct the statistical significance of 20 SNPs with the risk of lung cancer. The Pearson's Х2 test was used to compare the distributions of gender, TNM stage, histopathological type, smoking and family history by lung susceptibility genotypes. Kaplan-Meier and Cox regression analyses were carried out to evaluate the associations between genetic variants and overall survival.Four of the 20 SNPs identified as high-risk SNPs in Chinese esophageal cancer showed increased risk for Chinese lung cancer, which included rs3769823 (OR = 1.26; 95% CI = 1.107-1.509; P = 0.02, rs10931936 (OR = 1.283; 95% CI = 1.100-1.495; P = 0.04, rs2244438 (OR = 1.294; 95% CI = 1.098-1.525; P = 0.04 and rs13016963 (OR = 1.268; 95% CI = 1.089-1.447; P = 0.04.

From 1967 through 1985, 86 patients with cancer of the paranasal sinuses and 6 patients with cancer of the nasal cavity (excluding sarcoma) were treated by irradiation at the Department of Radiology, Kumamoto National Hospital. The mean age was 60.7. The rate of men to women was 1.2 : 1. The results were as follows ; 1) Fifty-nine patients (51 cases of maxillary sinus carcinoma, 4 of ethmoid sinus carcinoma, and 4 of cancer of the nasal cavity) were treated with antrostomy followed by radiotherapy and regional arterial infusion of 5-fluorouracil alone or a combination of 5-fluorouracil and bleomycin. In 11 cases of these, salvage with total maxillectomy was performed and 10 % of which were controlled for more than five years. In 9 cases of these, no case was salvaged with radiotherapy. An overall five-year survival rate was 32 %. 2) The survival rate of the postoperative irradiation (11 cases of maxillary sinus carcinoma, 1 of cancer of the nasal cavity) was 42 % at 2 and 4 years after the operations. 3) Twelve patients with cancer of the paranasal sinuses (11 cases of maxillary sinus carcinoma, 1 of ethmoid sinus carcinoma) survived more than five years. All of them were irradiated curatively with doses more than 40 Gy. In our series, there was no difference in long-term survival between 5-fluorouracil alone and a combination of 5-fluorouracil and bleomycin. (author)

Full Text Available Background: Triple-negative (TN breast cancer is a subtype of breast cancer characterised by a loss of estrogen receptor (ER, progesterone receptor (PR expression, and the absence of human epidermal growth factor (HER2 overexpression. Aims: To identify the relationships between clinicopathological characteristics of TN breast cancers in the northeast region of Turkey and disease free survival (DFS and overall survival (OS. Study Design: Retrospective clinical study. Methods: Seven hundred and eighty non-metastatic breast cancer patients were enrolled in this study. The relationships between TN breast cancer and other breast cancers with respect to clinicopathological characteristics, as well as DFS and OS, were studied. Results: The triple-negative phenotype was detected in 204 patients (27.1%. Patients with triple-negative breast cancer had more grade 2-3 tumours compared to those with other types of breast cancer (92.5% versus 84.3%, p=0.004. Invasive ductal carcinoma histology, on the other hand, was less prevalent in patients with TN breast cancer (77% versus 84.5%, p=0.016. No significant differences were identified between the groups in other clinicopathological variables. Relapse and mortality rates were higher in the TN group during the follow-up of both groups [57 (27.9% versus 89 (16.2%, p<0.001 for relapse; 27 (13.2% versus 37 (6.8%, p=0.005 for mortality]. The univariate analysis demonstrated shorter DFS and OS for patients with TN breast cancer compared to those with other types of breast cancer. In the multivariate analysis, patients with TN breast cancer were 2.21 times more likely to develop relapse, while the likelihood of death increased 3.21-fold (p<0.001 and p<0.001. Conclusion: Triple-negative breast cancers demonstrate a more aggressive clinical course compared to other breast cancers. More effective strategies should be developed for the treatment of this subgroup of breast cancer.

Full Text Available The phenomenon of the present postal services is the fact that, customers expect the lowest price while maintaining the availability, security and on time delivery of mail items. We can find that, the costs associated with transport of the postal substrate is one of the most important factors affecting the total cost of the postal services. These transport costs depend on various factors such as the investment in vehicles purchase, operational costs of the postal vehicles (costs of maintenance, repairs, fuel costs of the vehicle, etc. labour costs of the drivers and so on. For this reason, it is important to find such an operational - organizational solutions that can reduce the costs associated with the transportation of postal shipments, resulting in reducing the total cost of postal services. One option to do this is to minimize the length of postal transportation routes. This article presents the approach based on the application of graph theory to optimize existing connections of postal logistics network. Published results is oriented to revaluate existing position of local centre and find a location for the new local distribution centre potentially. New location of local distribution centre can to optimize (minimize the total transport costs of the local postal transportation network in area of the Lublin Province.

Quantitative high-resolution genomic analysis of single cancer cells.

Full Text Available During cancer progression, specific genomic aberrations arise that can determine the scope of the disease and can be used as predictive or prognostic markers. The detection of specific gene amplifications or deletions in single blood-borne or disseminated tumour cells that may give rise to the development of metastases is of great clinical interest but technically challenging. In this study, we present a method for quantitative high-resolution genomic analysis of single cells. Cells were isolated under permanent microscopic control followed by high-fidelity whole genome amplification and subsequent analyses by fine tiling array-CGH and qPCR. The assay was applied to single breast cancer cells to analyze the chromosomal region centred by the therapeutical relevant EGFR gene. This method allows precise quantitative analysis of copy number variations in single cell diagnostics.

The CMS Collaboration relies on 7 globally distributed Tier-1 computing centres located at large universities and national laboratories for a second custodial copy of the CMS RAW data and primary copy of the simulated data, data serving capacity to Tier-2 centres for analysis, and the bulk of the reprocessing and event selection capacity in the experiment. The Tier-1 sites have a challenging role in CMS because they are expected to ingest and archive data from both CERN and regional Tier-2 centres, while they export data to a global mesh of Tier-2s at rates comparable to the raw export data rate from CERN. The combined capacity of the Tier-1 centres is more than twice the resources located at CERN and efficiently utilizing this large distributed resources represents a challenge. In this article we will discuss the experience building, operating, and utilizing the CMS Tier-1 computing centres. We will summarize the facility challenges at the Tier-1s including the stable operations of CMS services, the ability to scale to large numbers of processing requests and large volumes of data, and the ability to provide custodial storage and high performance data serving. We will also present the operations experience utilizing the distributed Tier-1 centres from a distance: transferring data, submitting data serving requests, and submitting batch processing requests.

Fitting canine cancer incidences through a conventional regression model assumes constant statistical relationships across the study area in estimating the model coefficients. However, it is often more realistic to consider that these relationships may vary over space. Such a condition, known as spatial non-stationarity, implies that the model coefficients need to be estimated locally. In these kinds of local models, the geographic scale, or spatial extent, employed for coefficient estimation may also have a pervasive influence. This is because important variations in the local model coefficients across geographic scales may impact the understanding of local relationships. In this study, we fitted canine cancer incidences across Swiss municipal units through multiple regional models. We computed diagnostic summaries across the different regional models, and contrasted them with the diagnostics of the conventional regression model, using value-by-alpha maps and scalograms. The results of this comparative assessment enabled us to identify variations in the goodness-of-fit and coefficient estimates. We detected spatially non-stationary relationships, in particular, for the variables related to biological risk factors. These variations in the model coefficients were more important at small geographic scales, making a case for the need to model canine cancer incidences locally in contrast to more conventional global approaches. However, we contend that prior to undertaking local modeling efforts, a deeper understanding of the effects of geographic scale is needed to better characterize and identify local model relationships.

Microenvironment-Centred Dynamics in Aggressive B-Cell Lymphomas

Directory of Open Access Journals (Sweden)

Matilde Cacciatore

2012-01-01

Full Text Available Aggressive B-cell lymphomas share high proliferative and invasive attitudes and dismal prognosis despite heterogeneous biological features. In the interchained sequence of events leading to cancer progression, neoplastic clone-intrinsic molecular events play a major role. Nevertheless, microenvironment-related cues have progressively come into focus as true determinants for this process. The cancer-associated microenvironment is a complex network of nonneoplastic immune and stromal cells embedded in extracellular components, giving rise to a multifarious crosstalk with neoplastic cells towards the induction of a supportive milieu. The immunological and stromal microenvironments have been classically regarded as essential partners of indolent lymphomas, while considered mainly negligible in the setting of aggressive B-cell lymphomas that, by their nature, are less reliant on external stimuli. By this paper we try to delineate the cardinal microenvironment-centred dynamics exerting an influence over lymphoid clone progression in aggressive B-cell lymphomas.

Evidence for triple-junction rifting focussed on local magmatic centres along Parga Chasma, Venus

Graff, J. R.; Ernst, R. E.; Samson, C.

2018-05-01

Parga Chasma is a discontinuous rift system marking the southern boundary of the Beta-Atla-Themis (BAT) region on Venus. Along a 1500 km section of Parga Chasma, detailed mapping of Magellan Synthetic Aperture Radar images has revealed 5 coronae, 11 local rift zones distinct from a regional extension pattern, and 47 graben-fissure systems with radiating (28), linear (12) and circumferential (7) geometries. The magmatic centres of these graben-fissure systems typically coincide with coronae or large volcanoes, although a few lack any central magmatic or tectonic feature (i.e. are cryptic). Some of the magmatic centres are interpreted as the foci of triple-junction rifting that form the 11 local rift zones. Cross-cutting relationships between graben-fissure systems and local rift faults reveal synchronous formation, implying a genetic association. Additionally, cross-cutting relationships show that local rifting events postdate the regional extension along Parga Chasma, further indicating multiple stages of rifting. Evidence for multiple centres of younger magmatism and local rifting against a background of regional extension provides an explanation for the discontinuous morphology of Parga Chasma. Examination of the Atlantic Rift System (prior to ocean opening) on Earth provides an analogue to the rift morphologies observed on Venus.

China carries a heavy burden of cervical cancer (CC) and substantial disparities exist across regions within the country. In order to reduce regional disparities in CC, the government of China launched the National Cervical Cancer Screening Program in Rural Areas (NCCSPRA) in 2009. Critical to the success of the program are the health care workers who play a pivotal role in preventing and managing CC by encouraging and motivating women to use screening services and by providing identification and treatment services. This study aimed to assess cervical cancer knowledge among these health care workers at the county level in maternal and child health (MCH) hospitals across different socio-economic regions of China. A cross-sectional survey was conducted and self-administered questionnaires were sent to all health care workers (a total of 66) providing cervical cancer screening services in 6 county level MCH hospitals in Liaoning, Hubei and Shaanxi provinces, representing eastern, central and western regions of China; 64 (97.0%, 64/66) of the workers responded. ANOVA and Chi-square test were used to compare the knowledge rate and scores in subgroups. The knowledge level of the respondents was generally low. The overall combined knowledge rate was 46.9%. The knowledge rates for risk factors, prevention, clinical symptoms, screening and diagnostic tests and understanding of positive results were 31.3%, 37.5%, 18.1%, 56.3% and 84.4%, respectively. Statistically significant differences in scores or rates of CC knowledge were seen across the different regions. The total and sectional scores in the less developed regions were statistically significantly lower than in the other regions. The majority of the health care workers who provide CC screening service in NCCSPRA at county level MCH hospitals do not have adequately equipped with knowledge about CC. Given the importance of knowledge to the program's success in reducing CC burden in rural women in China, efforts are

The global response to the 12 January 2010 earthquake in Haiti revealed the ability to mobilise medical teams quickly and effectively when academic medical centres partner non-governmental organisations (NGO) that already have a presence in a zone of devastation. Most established NGOs based in a certain region are accustomed to managing the medical conditions that are common to that area and will need additional and specialised support to treat the flux of myriad injured persons. Furthermore, an NGO with an established presence in a region prior to a disaster appears better positioned to provide sustained recovery and rehabilitation relief. Academic medical centres can supply these essential specialised resources for a prolonged time. This relationship between NGOs and academic medical centres should be further developed prior to another disaster response. This model has great potential with regard to the rapid preparation and worldwide deployment of skilled medical and surgical teams when needed following a disaster, as well as to the subsequent critical recovery phase. © 2012 The Author(s).

Tb 3+ doped CaZrO 3 has been prepared by an easy solution combustion synthesis method. The combustion derived powder was investigated by X-ray diffraction, Fourier-transform infrared spectrometry and scanning electron microscopy techniques. A room temperature photoluminescence study showed that the phosphors can be efficiently excited by 251 nm light with a weak emission in the blue and orange region and a strong emission in green light region. CaZrO 3 :Tb 3+ exhibits three thermoluminescence (TL) glow peaks at 126 °C, 200 °C and 480 °C. Electron Spin Resonance (ESR) studies were carried out to study the defect centres induced in the phosphor by gamma irradiation and also to identify the centres responsible for the TL peaks. The room temperature ESR spectrum of irradiated phosphor appears to be a superposition of two distinct centres. One of the centres (centre I) with principal g-value 2.0233 is identified as an O − ion. Centre II with an axial symmetric g-tensor with principal values g ⊥ =1.9986 and g ⊥ =2.0023 is assigned to an F + centre (singly ionised oxygen vacancy). An additional defect centre is observed during thermal annealing experiments and this centre (assigned to F + centre) seems to originate from an F centre (oxygen vacancy with two electrons). The F centre and also the F + centre appear to correlate with the observed high temperature TL peak in CaZrO 3 :Tb 3+ phosphor. - Highlights: ► Powder phosphor of CaZrO 3 :Tb 3+ was prepared by an easy solution combustion synthesis method. ► The phosphor exhibits a bright green emission at 545 nm ( 5 D 4 → 7 F 5 ) of the Tb 3+ ion. ► Electron Spin Resonance studies have been carried out to identify the defect centres responsible for the observed thermoluminescence peaks.

The aim of this study was to determine the rate of blood component wastage before and after interventions at Yazd Blood Transfusion Center. The growing need for blood components along with blood safety issues and rising costs constantly pressurise blood centres to improve their efficiency. Reducing the quantity of discarded blood at all stages of the supply chain can decrease the total costs. Data on discarded blood components were extracted from the database of Yazd Blood Transfusion Center. Multiple interventions, including implementation of wastage management standard operating procedures and reduction of red blood cells (RBCs) inventory level, were implemented. Discard rates of blood components in the 3 years after intervention (2013-2015) were compared with the discard rates in the 3 years before interventions. The total wastage rate of blood components decreased by almost 60%. Discard rates of RBCs, platelets and plasma decreased from 9·7%, 18·5% and 5·4% to 2·9%, 10·5% and 2·3%, (P supply saving. © 2017 British Blood Transfusion Society.

2010-01-01

Quantum-chemical modelling based on the Hartree-Fock methodology and a periodic supercell model is done to study oxygen vacancy and F-type centres in the perovskite-type MgSiO 3 crystal. The equilibrium geometry of defects is obtained, confirming the importance of electrostatic interaction in determination of atomic shifts. The calculated relaxation energies due to the defect formation are between 8 and 10 eV, thus evidencing favourability in the occurrence of such defects. The wave functions describing both F + and F centres are rather diffuse and the point defects are not well localised within the oxygen vacancy region. The Δ SCF computed absorption energies due to the F-type centres fall well within the ultraviolet spectrum, between 136 and 254 nm for the F + centre and between 163 and 248 nm for the F centre.

Guidelines for radiation oncology centres in AFRA Member States intending to make a transition from 2-D to 3-D treatment planning and delivery

The IAEA Regional Technical Cooperation Project RAF/6/031 on Medical Physics in Support of Cancer Management aims to strengthen national and regional medical physics capabilities to sustain radiotherapy treatments in the AFRA1 Member States. In particular, it aims at increasing the number of qualified medical physicists in the region as well as improving the level of medical physics by establishing regional training and continuous development programmes. Eighteen National Project Coordinators (NPCs) nominated by participating AFRA Member States are engaged in the project. RAF/6/031 was approved by the IAEA in 2005 for an initial five year duration. A coordination meeting is held every two years where the NPCs and IAEA Technical and Project Management Officers establish the project's training and development programmes. During the first coordination meeting at Cape Town in November 2005, it was decided to convene a Task Force Meeting to review the status of treatment planning in radiotherapy in AFRA Member States and prepare a guidance document on the transition from 2-D to 3-D treatment planning. This Task Force Meeting took place at the IAEA's Headquarters in Vienna on 23-26 April 2007. The resulting guidance document highlights the milestones that have to be achieved by radiotherapy centres routinely implementing 2-D computerized treatment planning before making a transition to 3-D treatment planning and delivery. The implementation of 3-D planning by radiotherapy centres that have not yet met these milestones could lead to serious mistakes in treatments. A self-assessment questionnaire was also prepared during the Task Force Meeting. Member States that are planning to make a transition to 3-D planning are advised to assess their existing capabilities through this questionnaire. The same questionnaire could also be useful for the IAEA staff and external experts when assessing the readiness of a radiotherapy centre to make a safe and effective transition to 3-D
