    Full Text Available Introduction Population-based cancer registries attempt to collect, process, analyze, store and interpret data on persons with cancer in a certain population (most frequently a geographical area. Hospital-based cancer registries register all cases in a given hospital, usually without knowledge of the background population; the emphasis is to serve the needs of the hospital administration, the hospital cancer program, and, above all, the individual patient. History of Cancer Registries Registration of persons suffering from cancer is a slow process. Around the year 1900, England and Germany demanded improvement of statistical investigation on spread of cancer in population in order to undertake etiological researches. The oldest example of a modern cancer registry is that in Hamburg. Today there are more than 200 population-based cancer registries, but they cover only 5% of the world population, mainly in developed countries of the world. Cancer registry of Vojvodina Cancer registry of Vojvodina was established in 1966; it is a member of International Agency for Research on Cancer (IARC and it is still the only cancer registry from our country whose data are cited in scientific monographs of IARC. The main purpose of cancer registries is to produce statistics on the occurrence of cancer in a defined populatin and to provide a framework for assessing and controlling the impact of cancer on the community. Cancer registries are essential parts of any rational program of cancer control. Their data can be used in a wide variety of areas of cancer control, ranging from etiological research in epidemiology, through primary and secondary prevention to health-care planning and patient care, so benefiting both the individual and society.

    The Dutch Hereditary Cancer Registry was established in 1985 with the support of the Ministry of Health (VWS). The aims of the registry are: (1) to promote the identification of families with hereditary cancer, (2) to encourage the participation in surveillance programs of individuals at high risk, (3) to ensure the continuity of lifelong surveillance examinations, and (4) to promote research, in particular the improvement of surveillance protocols. During its early days the registry provided assistance with family investigations and the collection of medical data, and recommended surveillance when a family fulfilled specific diagnostic criteria. Since 2000 the registry has focused on family follow-up, and ensuring the quality of surveillance programs and appropriate clinical management. Since its founding, the registry has identified over 10,000 high-risk individuals with a diverse array of hereditary cancer syndromes. All were encouraged to participate in prevention programmes. The registry has published a number of studies that evaluated the outcome of surveillance protocols for colorectal cancer (CRC) in Lynch syndrome, as well as in familial colorectal cancer. In 2006, evaluation of the effect of registration and colonoscopic surveillance on the mortality rate associated with colorectal cancer (CRC) showed that the policy led to a substantial decrease in the mortality rate associated with CRC. Following discovery of MMR gene defects, the first predictive model that could select families for genetic testing was published by the Leiden group. In addition, over the years the registry has produced many cancer risk studies that have helped to develop appropriate surveillance protocols. Hereditary cancer registries in general, and the Lynch syndrome registry in particular, play an important role in improving the clinical management of affected families. PMID:26973060

    Colorectal cancer is emerging as one of the commonest cancers in Malaysia. Data on colorectal cancer from the National Cancer Registry is very limited. Comprehensive information on all aspects of colorectal cancer, including demographic details, pathology and treatment outcome are needed as the management of colorectal cancer has evolved rapidly over the years involving several disciplines including gastroenterology, surgery, radiology, pathology and oncology. This registry will be an important source of information that can help the development of guidelines to improve colorectal cancer care relevant to this country. The database will initially recruit all colorectal cancer cases from eight hospitals. The data will be stored on a customized web-based case report form. The database has begun collecting data from 1 October 2007 and will report on its first year findings at the end of 2008. PMID:19230248

    The Pancreatic Cancer Collaborative Registry (PCCR) is a multi-institutional web-based system aimed to collect a variety of data on pancreatic cancer patients and high-risk subjects in a standard and efficient way. The PCCR was initiated by a group of experts in medical oncology, gastroenterology, genetics, pathology, epidemiology, nutrition, and computer science with the goal of facilitating rapid and uniform collection of critical information and biological samples to be used in developing diagnostic, prevention and treatment strategies against pancreatic cancer. The PCCR is a multi-tier web application that utilizes Java/JSP technology and has Oracle 10 g database as a back-end. The PCCR uses a "confederation model" that encourages participation of any interested center, irrespective of its size or location. The PCCR utilizes a standardized approach to data collection and reporting, and uses extensive validation procedures to prevent entering erroneous data. The PCCR controlled vocabulary is harmonized with the NCI Thesaurus (NCIt) or Systematized Nomenclature of Medicine-Clinical Terms (SNOMED-CT). The PCCR questionnaire has accommodated standards accepted in cancer research and healthcare. Currently, seven cancer centers in the USA, as well as one center in Italy are participating in the PCCR. At present, the PCCR database contains data on more than 2,700 subjects (PC patients and individuals at high risk of getting this disease). The PCCR has been certified by the NCI Center for Biomedical Informatics and Information Technology as a cancer Biomedical Informatics Grid (caBIG(®)) Bronze Compatible product. The PCCR provides a foundation for collaborative PC research. It has all the necessary prerequisites for subsequent evolution of the developed infrastructure from simply gathering PC-related data into a biomedical computing platform vital for successful PC studies, care and treatment. Studies utilizing data collected in the PCCR may engender new approaches

    The cancer registry profession has grown dramatically since its inception in 1926. Certified tumor registrars (CTRs) have become an integral part of the cancer care team by providing quality cancer data for research, statistical purposes, public health, and cancer control. In addition, CTRs have been found to be valuable in other cancer and health-related fields. Based on the need for high-quality, accurate data, the National Cancer Registrars Association (NCRA), the certification body for CTRs, has increased the educational requirement for eligibility for the CTR certification exam. This has resulted in fewer individuals who are able to meet the requirements for CTR certification. In addition, the existing cancer registry workforce is, on average, older than other allied health professions, and therefore will face an increasing number of retirements in the next few years. The high demand for CTRs, the decreased pool of CTR-eligible applicants, and the aging cancer registry workforce has resulted in an existing shortage that will only get worse as the population ages and the incidence of cancer increases. Health information management (HIM) students are well suited to pursuing further training in the cancer registry field and gaining the CTR credential. HIM students or new graduates have the needed skill set and education to pursue a cancer registry career. There are many avenues HIM educational programs can take to encourage students to pursue CTR certification and a cancer registry career. Including cancer registry functions in courses throughout the HIM curriculum, bringing in cancer registry speakers, encouraging networking, and promoting the cancer registry field and profession in general are just a few of the methods that HIM programs can use to raise awareness of and promote a cancer registry career to their students. Illinois State University has used these methods and has found them to be successful in encouraging a percentage of their graduates to pursue

  16. The role of cancer registries in cancer control.

    2008-04-01

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

    Cancer registries help to establish and maintain cancer incidence reporting systems, serve as a resource for investigation of cancer and its causes, and provide information for planning and evaluation of preventive and control programs. However, their wider role in directly enhancing oncology drug access has not been fully explored. We examined the value of cancer registries in oncology drug access in the Asia-Pacific region on three levels: (1) specific registry variable types; (2) macroscopic strategies on the national level; and (3) a regional cancer registry network. Using literature search and proceedings from an expert forum, this paper covers recent cancer registry developments in eight economies in the Asia-Pacific region - Australia, China, Hong Kong, Malaysia, Singapore, South Korea, Taiwan, and Thailand - and the ways they can contribute to oncology drug access. Specific registry variables relating to demographics, tumor characteristics, initial treatment plans, prognostic markers, risk factors, and mortality help to anticipate drug needs, identify high-priority research area and design access programs. On a national level, linking registry data with clinical, drug safety, financial, or drug utilization databases allows analyses of associations between utilization and outcomes. Concurrent efforts should also be channeled into developing and implementing data integrity and stewardship policies, and providing clear avenues to make data available. Less mature registry systems can employ modeling techniques and ad-hoc surveys while increasing coverage. Beyond local settings, a cancer registry network for the Asia-Pacific region would offer cross-learning and research opportunities that can exert leverage through the experiences and capabilities of a highly diverse region.

    Objective: 16,922 patients with cancers from 15 sites of Qidong population-based cancer registry in the period of 1982-1991 were analyzed for evaluation of cancer survival as well as different cancer control measures.Methods: Observed survival rate (OS) was computed by the Kaplan-Meier method using EGRET statistical software package. Relative survival (RS) which is the ratio of the OS to the expected rate was calculated by using Qidong life table with respect to sex, age and calendar period of observation. Results: The five-year OS for the 5 leading sites of cancers, liver, stomach, lung,oesophagus, and rectum were 1.8%, 11.6%, 3.0% 3.3%,and 19.9%, respectively. The five-year RS for the 5 sites were 1.9%, 14.0%, 3.6%, 4.2%, and 23.7%, respectively,in which, 1.7%, 14.8%, 3.4%, 4.2%, and 26.0% for males, and 2.7%, 12.7%, 4.1%, 4.0%, and 22.0% for females, respectively. Female patients with breast cancer and cervix cancer had 5-year RS of 54.6% and 33.0%.Conclusion: Cancer survival rates for all sites are poor,in which that of the liver is the lowest, while that of the breast, the highest. The survivals of cancers for all sites,especially for breast, cervix, and leukemia are seen to be lower than those of European countries except for oesophagus, pancreas and lung cancer which do not achieve improved survival both in developing and developed countries. There will be a long way to improve the total cancer survival, as well as the cancer treatment in the developing countries.

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

  3. Clinical Cancer Registries - Are They Up for Health Services Research?

    Clinical cancer registries are a valuable data source for health services research (HSR). HSR is in need of high quality routine care data for its evaluations. However, the secondary use of routine data - such as documented cancer cases in a disease registry - poses new challenges in terms of data quality, IT-management, documentation processes and data privacy. In the clinical cancer registry Heilbronn-Franken, real-world data from the Giessen Tumor Documentation System (GTDS) was utilized for analyses of patients' disease processes and guideline adherence in follow-up care. A process was developed to map disease state definitions to fields of the GTDS database and extract patients' disease progress information. Thus, the disease process of sub-cohorts could be compared to each other, e.g., comparison of disease free survival of HER2 (human epidermal growth factor receptor 2)-positive and -negative women who were treated with Trastuzumab, a targeted therapy applied in breast cancer. In principle, such comparisons are feasible and of great value for HSR as they depict a routine care setting of a diverse patient cohort. Yet, local documentation practice, missing flow of information from external health care providers or small sub-cohorts impede the analyses of clinical cancer registries data bases and usage for HSR.

    Reactive Oxygen Species (ROS) are important in the pathogenesis of many diseases, including breast cancer. Several population-based case-control studies have demonstrated that various biomarkers of oxidative stress are associated with an increase in breast cancer risk. We selected sisters discordant for breast cancer (n=645) from the New York site of the Breast Cancer Family Registry to explore factors that contribute to variation in plasma protein carbonyls, and to determine whether this bio...

    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. PMID:26644751

    Breast cancer is the leading type of malignancy and the leading cause of cancer-related deaths in women worldwide. The screening programs and advances in the treatment of patients with breast cancer have led to an increase in overall survival. Cancer registry systems play an important role in providing basic data for research and the monitoring of the cancer status. In this study, the results of the 10-year national cancer registry (NCR) of Iran in breast cancer are reviewed. NCR database records were searched for primary breast cancer records according to ICD-O-3 coding and the cases were reviewed. A total of 52,068 cases were found with the coding of primary breast cancer. Females constituted 97.1% of the cases. Breast cancer was the leading type of cancer in Iranian females, accounting for 24.6% of all cancers. The mean age of the women with breast cancer was 49.6 years (95%CI 49.5-49.6). Most of the cases (95.7%) were registered as having invasive pathologies (behavior code 3). The most common morphology of primary breast cancer was invasive ductal carcinoma (ICD-O 8500/3) followed by invasive lobular carcinoma (ICD-O 8520/3) with relative frequencies of 77.8% and 5.2%, respectively. The average annual crude incidence of primary breast cancer in females was 22.6 (95%CI 22.1-23.1) per 100,000 females, with an age-standardized rate (ASR) of 27.4 (95%CI 22.5-35.9). There were no data on survival, staging or immunohistochemical marker(s) of the breast-cancer-registered cases. The incidence of breast cancer in Iran is lower than in low-middle-income neighboring countries. The NCR data registry of breast cancer is not accurate in monitoring the effect of screening programs or determining the current status of breast cancer in Iran. Screening programs of breast cancer in Iran have failed to enhance the detection of the patients with in situ lesion detection. A quality breast cancer registry and a screening program for breast cancer are both needed. PMID:26070507

    The hospital registry is a valuable tool for evaluating quality benchmarks in cancer care. As payment for performance standards are adopted, the registry will assume a more dynamic and economically important role in the hospital setting. At Carolinas Medical Center, the registry has been a key instrument in the comparison of state and national benchmarks and for program improvement in meeting standards in the care of breast and colon cancer. One of the significant successes of the American College of Surgeons Commission on Cancer (CoC) Hospital Approvals Program is the support of hospital registries, especially in small and midsized community hospitals throughout the United States. To become a member of the Hospital Approvals Program, a registry must be staffed appropriately and include analytic data for patients who have their primary diagnosis or treatment at the facility 1. The current challenge for most hospitals is to prove that the registry has specific worth when many facets of care are not compensated. Unfortunately a small number of hospitals have disbanded their registries because of the short-sighted decision that the registry and its personnel are a drain on the hospital system and do not generate revenue. In the present era of meeting benchmarks for care as a prelude to being paid by third party and governmental agencies 2,3, a primary argument is that the registry can be revenue-enhancing by quantifying specific outcomes in cancer care. Without having appropriate registry and abstract capability, the hospital leadership cannot measure the specific outcome benchmarks required in the era of "pay for performance" or "pay for participation".

    AIM:To describe the clinical and epidemiologic profiles of the disease and to compare the findings with those generated from the previous hospital-based studies.METHODS:The Gharbiah cancer registry is the only population-based cancer registry in Egypt since 1998.We analyzed the data of all colorectal cancer patients included in the registry for the period of 1999-2007.All medical records of the 1364 patients diagnosed in Gharbiah during the study period were retrieved and the following information abstracted:age,residence,diagnosis date,grade,stage,topology,clinical characteristics,and histology variables.Egyptian census data for 1996 and 2006 were used to provide the general population's statistics on age,sex,residence and other related demographic factors.In addition to age-and sex-specific incidence rate analyses,we analyze the data to explore the incidence distribution by rural-urban differences among the 8 districts of the province.We also compared the incidence rates of Gharbiah to the rates of the Surveillance Epidemiology and End Results (SEER) data of the United States.RESULTS:Over the 9 year-period,1364 colorectal cancer cases were included.The disease incidence under age 40 years was relatively high (1.3/105) while the incidence in the age groups 40 and over was very low (12.0/105,19.4/105 and 21.2/105 in the age groups 40-59 years,60-69 years and > 70 years,respectively).The vast majority of tumors (97.2%) had no polyps and 37.2% of the patients presented with primary lesions in the rectum.Colorectal cancer was more common in patients from urban (55%) than rural (45%) areas.Regional differences in colon and rectal cancer incidence in the 8 districts of the study province may refleet different etiologic patterns in this population.The registry data of Egypt shows a slightly higher incidence of colorectal cancer than the United States in subjects under age 40 years.The results also shows significantly lower incidence of colorectal cancer in

    Full Text Available The epidemiologic transition in sub-Saharan Africa (SSA has given rise to a concomitant increase in the incidence of non-communicable diseases including cancers. Worldwide, cancer registries have been shown to be critical for the determination of cancer burden, conduct of research, and in the planning and implementation of cancer control measures. Cancer registration though vital is often neglected in SSA owing to competing demands for resources for healthcare.We report the implementation of a system for representative nation-wide cancer registration in Nigeria - the Nigerian National System of Cancer Registries (NSCR. The NSCR coordinates the activities of cancer registries in Nigeria, strengthens existing registries, establishes new registries, complies and analyses data, and makes these freely available to researchers and policy makers. We highlight the key challenges encountered in implementing this strategy and how they were overcome. This report serves as a guide for other low and middle income countries (LMIC wishing to expand cancer registration coverage in their countries and highlights the training, mentoring, scientific and logistic support, and advocacy that are crucial to sustaining cancer registration programs in LMIC

    Full Text Available Abstract Background Little is known about the effect of migrant status on childhood cancer survival. We studied cancer survival among children of Turkish descent in the German Cancer Childhood Registry, one of the largest childhood cancer registries worldwide. Methods We identified children of Turkish descent among cancer cases using a name-based approach. We compared 5-year survival probabilities of Turkish and other children in three time periods of diagnosis (1980–87, 1988–95, 1996–2005 using the Kaplan-Meier method and log-rank tests. Results The 5-year survival probability for all cancers among 1774 cases of Turkish descent (4.76% of all 37.259 cases was 76.9% compared to 77.6% in the comparison group (all other cases; p = 0.15. We found no age- or sex-specific survival differences (p-values between p = 0.18 and p = 0.90. For the period 1980–87, the 5-year survival probability among Turkish children with lymphoid leukaemia was significantly lower (62% versus 75.8%; p Conclusion Our results suggest that nowadays Turkish migrant status has no bearing on the outcome of childhood cancer therapies in Germany. The inclusion of currently more than 95% of all childhood cancer cases in standardised treatment protocols is likely to contribute to this finding.

    Objective. Use of cancer cases from registries and PMSI claims database to estimate Département-specific incidence of four major cancers. Methods. Case extraction used principal diagnosis then surgery codes. PMSI cases/registry cases ratios for 2004 were modelled then Département-specific incidence for 2007 estimated using these ratios and 2007 PMSI cases. Results. For 2007, only colon-rectum and breast cancer estimations were satisfactorily validated for infranational incidence not ovary and kidney cancers. For breast, the estimated national incidence was 50,578 cases and the incidence rate 98.6 cases per 100,000 person per year. For colon-rectum, incidence was 21,172 in men versus 18,327 in women and the incidence rate 38 per 100,000 versus 24.8. For ovary, the estimated incidence was 4,637 and the rate 8.6 per 100,000. For kidney, incidence was 6,775 in men versus 3,273 in women and the rate 13.3 per 100.000 versus 5.2. Conclusion. Incidence estimation using PMSI patient identifiers proved encouraging though still dependent on the assumption of uniform cancer treatments and coding. PMID:21527984

    Melanoma is often managed outside hospital settings, creating the potential for underreporting to cancer registries. To our knowledge, completeness of melanoma capture in cancer registries has not been assessed using external data sources since the 1980s. We evaluated the melanoma capture rate from 1993 to 2009 in a provincial cancer registry. We identified all melanoma diagnoses in pathology reports from a major community laboratory in Ontario, Canada. Pathologically confirmed diagnoses were linked to Ontario Cancer Registry (OCR) records using health insurance numbers. We calculated capture rates as the proportion of patients with melanoma confirmed by a pathology report, with a corresponding melanoma diagnosis in OCR. OCR captured 3,798 of 4,275 (88.8, 95 % confidence interval: 87.9, 89.8 %) invasive melanoma diagnoses over the 17-year period. Annual capture rates of 94 % or higher were found for over half the study period. Among all 29,133 melanoma diagnoses in OCR, 27.6 % were registered based on a pathology report alone, compared with 3.4 % for non-cutaneous malignancies. This suggests that comprehensive capture of melanoma cases by a provincial cancer registry is achievable using source data from community laboratories. There is a need for ongoing validation to ensure data remain accurate and complete to reliably inform clinical care, research, and policy. PMID:26537120

    Full Text Available Abstract Background Data concerning incidence and prevalence of cancer in the different regions of Russia have traditionally not been provided on a basis that facilitated comparison with data from countries in western parts of Europe. The oncological hospital in Arkhangelsk, in co-operation with Universitetet i Tromsø (Norway, has established a population based cancer registry for Arkhangelskaja Oblast (AO. AO is an administrative unit with 1.3 million inhabitants in northwestern Russia. The aim of this investigation was to assess the content and quality of the AO cancer registry (AKR, and to present the site-specific cancer-incidence rates in AO in the period 1993–2001. Methods The population in this study consisted of all individuals registered as residents of AO. All new cancer cases in the period 1993 – 2001, registered the AKR, were included in the study (ICD-10: C00-C95, except for C77-78. The annual gender and age-group-specific population figures were obtained from the AO statistics office. Results A total of 34 697 cases of primary cancers were included. The age-adjusted (world standard incidence rate for all sites combined was 164/100 000 for women and 281/100 000 for men. The highest incidence was for cancer of the trachea, bronchus and lung (16.3% of all cases, whereof 88.6 % of the cases were among men. Among women, cancer of the breast constituted 15.9 percent of all cases. The age-adjusted incidences of the most frequent cancer sites among men were: lung (77.4/100 000; stomach (45.9; rectum (13.4; oesophagus (13.0; colon (12.2; bladder (11.6; and prostate cancer (11.1. Among women they were: breast (28.5; stomach (19.7; colon (12.2; and ovary cancer (9.0. Conclusion Our findings confirm and strengthen the indication that the incidences of stomach, larynx, liver, pancreas, prostate, colon, bladder and melanoma cancer are quite different in male populations in Russia compared to many other European countries. Among women, most

    Full Text Available Abstract Background Recruiting large and representative samples of adolescent and young adult (AYA cancer survivors is important for gaining accurate data regarding the prevalence of unmet needs in this population. This study aimed to describe recruitment rates for AYAs recruited through a cancer registry with particular focus on: active clinician consent protocols, reasons for clinicians not providing consent and the representativeness of the final sample. Methods Adolescents and young adults aged 14 to19 years inclusive and listed on the cancer registry from January 1 2002 to December 31 2007 were identified. An active clinician consent protocol was used whereby the registry sent a letter to AYAs primary treating clinicians requesting permission to contact the survivors. The registry then sent survivors who received their clinician's consent a letter seeking permission to forward their contact details to the research team. Consenting AYAs were sent a questionnaire which assessed their unmet needs. Results The overall consent rate for AYAs identified as eligible by the registry was 7.8%. Of the 411 potentially eligible survivors identified, just over half (n = 232, 56% received their clinician's consent to be contacted. Of those 232 AYAs, 65% were unable to be contacted. Only 18 AYAs (7.8% refused permission for their contact details to be passed on to the research team. Of the 64 young people who agreed to be contacted, 50% (n = 32 completed the questionnaire. Conclusions Cancer registries which employ active clinician consent protocols may not be appropriate for recruiting large, representative samples of AYAs diagnosed with cancer. Given that AYA cancer survivors are highly mobile, alternative methods such as treatment centre and clinic based recruitment may need to be considered.

The first report from this registry revealed that Ardabil has one of the highest rate of gastric cardia cancer and the lowest rate of cer­vical cancer in the world. We aim to update the cancer incidence in this area by the second follow up report from this registry."nMethod: Data on all newly diagnosed cancer cases between 2004 and 2006 were actively collected. CanReg4 software was used for data entry and the data of cancer-related death were obtained from the comprehensive death registry system."nResults: More than 4300 new cases were registered during 3 years. Diagnosis of cancer was based on histopathology in 69%, clinical investigation 8%, clinical only 5%, and Death Certificate Only (DCO in 18% of cases. In terms of age-stan­dardized rate (/100,000, the five leading cancers in men (excluding skin cancer were stomach (51.8, esophagus (19.5, blad­der (13.1, lung and bronchus (10.8, and colorectal (9.6; in women, they were stomach (24.9, esophagus (19.7, breast (11.9, colon and rectum (7.4, and brain tumors (6.9. According to death registration data, upper gastrointestinal can­cers constituted more than 43% of cancer-related death in Ardabil."nConclusions: The ASR for gastric cancer is among the highest rate for this cancer in male and female in the world. Most of the cancers, especially in female, have a significant increase compared to previous report from Ardabil. This is most likely due to the change in the registration practice.

    Cancer burden in Malaysia is increasing. Although there have been improvements in cancer treatment, these new therapies may potentially cause an exponential increase in the cost of cancer treatment. Therefore, justification for the use of these treatments is mandated. Availability of local data will enable us to evaluate and compare the outcome of our patients. This will help to support our clinical decision making and local policy, improve access to treatment and improve the provision and delivery of oncology services in Malaysia. The National Cancer Patient Registry was proposed as a database for cancer patients who seek treatment in Malaysia. It will be a valuable tool to provide timely and robust data on the actual setting in oncology practice, safety and cost effectiveness of treatment and most importantly the outcome of these patients.

    Full Text Available Abstract Background Cancer is a leading cause of morbidity and mortality worldwide with a majority of cases and deaths occurring in developing countries. While cancer of the lung, breast, colorectum, stomach and prostate are the most common types of cancer globally, in east and southern Africa these are less common and comprehensive data to inform policies are lacking. Methods Nationwide cancer registry was conducted between September and October 2010 in Malawi. New cancer cases registered from 2007 to 2010 were identified from hospital and clinic registers of 81 out of 84 health facilities providing cancer diagnosis, treatment or palliative care services. Demographic and cancer data were extracted from registers and case notes using a standard form. Results A total of 18,946 new cases of cancer were registered in Malawi from 2007-2010. Of these 55.9% were females, 7.2% were children aged less than 15 years, 76.5% were adults aged 15-59 years and 16.4% were elderly aged 60 years or more. Only 17.9% of the cases had histologically verified diagnosis, 33.2% were diagnosed clinically and 49.6% based on clinical and some investigations. Amongst females, cancer of the cervix was the commonest accounting for 45.4% of all cases followed by Kaposi sarcoma (21.1%, cancer of the oesophagus (8.2%, breast (4.6% and non-Hodgkin lymphoma (4.1%. In males, Kaposi sarcoma was the most frequent (50.7% then cancer of oesophagus (16.9%, non-Hodgkin lymphoma (7.8, prostate (4.0% and urinary bladder (3.7%. Age-standardised incidence rate per 100,000 population for all types of cancer in males increased from 31 in 1999-2002 to 56 in 2007-2010. In females it increased from 29 to 69. Kaposi sarcoma and cancer of the oesophagus, cervical cancer and Kaposi sarcoma were the main causes for the increased incidence in males and females respectively. It was estimated that, annually at least 8,151 new cases of cancer (all types occur in Malawi. Conclusions This study provided

    Background: Cancer is a major health problem in the developing countries. Variations of its incidence rate among geographical areas are due to various contributing factors. This study was performed to assess the spatial patterns of cancer incidence in the Fars Province, based on cancer registry data and to determine geographical clusters. Methods: In this cross sectional study, the new cases of cancer were recorded from 2001 to 2009. Crude incidence rate was estimated based on age groups and sex in the counties of the Fars Province. Age-standardized incidence rates (ASR) per 100,000 was calculated in each year. Spatial autocorrelation analysis was performed in measuring the geographic patterns and clusters using geographic information system (GIS). Also, comparisons were made between ASRs in each county. Results: A total of 28,411 new cases were diagnosed with cancer during 2001-2009 in the Fars Province, 55.5% of which were men. The average age was 61.6 ± 0.5 years. The highest ASR was observed in Shiraz, which is the largest county in Fars. The Moran's Index of cancer was significantly clustered in 2004, 2005, and 2006 in total, men, and women. The type of spatial clustering was high-high cluster, that to indicate from north-west to south-east of Fars Province. Conclusions: Analysis of the spatial distribution of cancer shows significant differences from year to year and between different areas. However, a clear spatial autocorrelation is observed, which can be of great interest and importance to researchers for future epidemiological studies, and to policymakers for applying preventive measures.

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

    Full Text Available Objectives: The aim of this study was to describe the epidemiology of breast cancer among the Bahraini female population in the years 2000‒2010 and examine its health policy implications. Methods: All breast cancer cases in the Bahrain Cancer Registry from 1st January 2000 to 31st December 2010 were included. Results: There were 1,005 cases, 12.7% of which were detected by screening. The overall mean age at diagnosis was 50.9 years (95% confidence interval 50.1–51.6. The age-standardised incidence rate declined from 58.2 per 100,000 in 2000 to 44.4 per 100,000 in 2010. The majority of cases were infiltrating ductal carcinoma (76.9%. Of the registered cases, 44.1% and 48.1% had an unknown grade and stage, respectively. The five-year survival rate was 63 ± 2%. Conclusion: The low percentage of cases detected by screening merits further evaluation of Bahrain’s screening programme. More effort should be made to reduce the proportion of unknown stage and grade breast cancers. Future research has to be directed towards understanding the reasons for Bahrain having the highest incidence rate of breast cancer in the Gulf Cooperation Council countries.

    Introduction The aim of this study was to investigate and analyze the incidence of early-onset colorectal cancer in Arizona, using the Arizona Cancer Registry. Methods We performed a retrospective analysis of patients with colorectal cancer reported in the Arizona Cancer Registry from 1995-2010. Outcome measure: incidence of CRC in patients younger than 50 years. Results 39,623 cases of colorectal cancer were reported to the Arizona Cancer Registry during a period of 15 years. Overall, there was a 17% decrease in the incidence of CRC. However, there was a 23% increase in incidence among patients in the age group 10-50. During the same time period, 15% and 41% increase in the incidence of colon and rectal cancer was observed, respectively. The most significant increase (102%) in overall CRC incidence was seen in the age group 10-29. The highest increase (110%) in incidence of colon cancer was observed in the same age group, while the most significant increase in incidence rates (225%) of rectal cancer was seen in the age group 30-34. Conclusion Although there is an overall decrease in incidence of colorectal cancer in Arizona, alarming increase in incidence of early-onset CRC was observed; mirroring the national trends.

    The rate of breast cancer screening for women of all ages in Japan is increasing. However, little is known about the biological differences between screen- and self-detected tumors. We used data from the Japanese Breast Cancer Registry (JBCR), a nationwide registry of newly diagnosed breast cancer cases in Japan, to investigate patients diagnosed between January 1, 2004 and December 31, 2011. We compared the clinicopathological features of tumors and assessed yearly trends regarding the proportion of screen-detected cases during the study period. We found that 31.8 % (65,358/205,544) of cancers were detected by screening. Asymptomatic tumors detected by screening (asymptomatic) were more likely to have favorable prognostic features than those that were self-detected (ductal carcinoma in situ [DCIS]: 19.8 versus 4.1 %, node-negative: 77.0 versus 61.6 %, and estrogen receptor-positive [ER+]: 82.0 versus 72.9 %, respectively). All these findings were statistically significant (p DCIS increased from 41.5 to 66.0 % and that of ER+ cancers increased from 23.2 to 39.7 %. This study demonstrated that low-risk tumors, including DCIS, ER+, and lower TNM stage, account for a substantial proportion of clinical screening-detected cancers. The differences in biological characteristics between screen- and self-detected cancers may account in part for the limited efficacy of breast cancer screening programs aimed at improving breast cancer mortality.

    Cancer represents the second most common cause of death in Germany. The country's federal states operate regional population-based cancer registries that collect and analyze data on cancer patients. This provides an essential basis for describing the cancer burden in the German population. In order to obtain valid and reliable information on cancer incidence at the national level, the Robert Koch Institute (RKI) set up the Federal Cancer Surveillance Unit in 1983 as a central institution for evaluating this cancer registry data. In August 2009, when the Federal Cancer Registry Data Act (BKRG) came into force, the Center for Cancer Registry Data (ZfKD) at the RKI took over the work of the Cancer Surveillance Unit with a broader remit. In the future, it will also regularly publish findings on survival, prevalence, and tumor stage distribution. A newly established record linkage process will help identify multiple submissions from the federal states. Further innovations and new tasks of the ZfKD include expanding an interactive Internet platform and encouraging a more intensive use of cancer registry data for epidemiological research by providing datasets to external scientists. The range of information available to the interested public is also to be expanded. PMID:22015795

  12. Survival of patients with metastatic breast cancer: twenty-year data from two SEER registries

    International Nuclear Information System (INIS)

    Many researchers are interested to know if there are any improvements in recent treatment results for metastatic breast cancer in the community, especially for 10- or 15-year survival. Between 1981 and 1985, 782 and 580 female patients with metastatic breast cancer were extracted respectively from the Connecticut and San Francisco-Oakland registries of the Surveillance, Epidemiology, and End Results (SEER) database. The lognormal statistical method to estimate survival was retrospectively validated since the 15-year cause-specific survival rates could be calculated using the standard life-table actuarial method. Estimated rates were compared to the actuarial data available in 2000. Between 1991 and 1995, further 752 and 632 female patients with metastatic breast cancer were extracted respectively from the Connecticut and San Francisco-Oakland registries. The data were analyzed to estimate the 15-year cause-specific survival rates before the year 2005. The 5-year period (1981–1985) was chosen, and patients were followed as a cohort for an additional 3 years. The estimated 15-year cause-specific survival rates were 7.1% (95% confidence interval, CI, 1.8–12.4) and 9.1% (95% CI, 3.8–14.4) by the lognormal model for the two registries of Connecticut and San Francisco-Oakland respectively. Since the SEER database provides follow-up information to the end of the year 2000, actuarial calculation can be performed to confirm (validate) the estimation. The Kaplan-Meier calculation for the 15-year cause-specific survival rates were 8.3% (95% CI, 5.8–10.8) and 7.0% (95% CI, 4.3–9.7) respectively. Using the 1991–1995 5-year period cohort and followed for an additional 3 years, the 15-year cause-specific survival rates were estimated to be 9.1% (95% CI, 3.8–14.4) and 14.7% (95% CI, 9.8–19.6) for the two registries of Connecticut and San Francisco-Oakland respectively. For the period 1981–1985, the 15-year cause-specific survival for the Connecticut and the San

    Purpose: To evaluate, in the setting of breast cancer, the accuracy of registry radiation therapy (RT) coding compared with the gold standard of Medicare claims. Methods and Materials: Using Surveillance, Epidemiology, and End Results (SEER)–Medicare data, we identified 73,077 patients aged ≥66 years diagnosed with breast cancer in the period 2001-2007. Underascertainment (1 - sensitivity), sensitivity, specificity, κ, and χ{sup 2} were calculated for RT receipt determined by registry data versus claims. Multivariate logistic regression characterized patient, treatment, and geographic factors associated with underascertainment of RT. Findings in the SEER–Medicare registries were compared with three non-SEER registries (Florida, New York, and Texas). Results: In the SEER–Medicare registries, 41.6% (n=30,386) of patients received RT according to registry coding, versus 49.3% (n=36,047) according to Medicare claims (P<.001). Underascertainment of RT was more likely if patients resided in a newer SEER registry (odds ratio [OR] 1.70, 95% confidence interval [CI] 1.60-1.80; P<.001), rural county (OR 1.34, 95% CI 1.21-1.48; P<.001), or if RT was delayed (OR 1.006/day, 95% CI 1.006-1.007; P<.001). Underascertainment of RT receipt in SEER registries was 18.7% (95% CI 18.6-18.8%), compared with 44.3% (95% CI 44.0-44.5%) in non-SEER registries. Conclusions: Population-based tumor registries are highly variable in ascertainment of RT receipt and should be augmented with other data sources when evaluating quality of breast cancer care. Future work should identify opportunities for the radiation oncology community to partner with registries to improve accuracy of treatment data.

    Full Text Available Recent genome-wide studies identified a risk locus for colorectal cancer at 18q21, which maps to the SMAD7 gene. Our objective was to confirm the association between SMAD7 SNPs and colorectal cancer risk in the multi-center Colon Cancer Family Registry.23 tagging SNPs in the SMAD7 gene were genotyped among 1,592 population-based and 253 clinic-based families. The SNP-colorectal cancer associations were assessed in multivariable conditional logistic regression.Among the population-based families, both SNPs rs12953717 (odds ratio, 1.29; 95% confidence interval, 1.12-1.49, and rs11874392 (odds ratio, 0.80; 95% confidence interval, 0.70-0.92 were associated with risk of colorectal cancer. These associations were similar among the population- and the clinic-based families, though they were significant only among the former. Marginally significant differences in the SNP-colorectal cancer associations were observed by use of nonsteroidal anti-inflammatory drugs, cigarette smoking, body mass index, and history of polyps.SMAD7 SNPs were associated with colorectal cancer risk in the Colon Cancer Family Registry. There was evidence suggesting that the association between rs12953717 and colorectal cancer risk may be modified by factors such as smoking and use of nonsteroidal anti-inflammatory drugs.

    Full Text Available Abstract Background Cancer risks of migrants might differ from risks of the indigenous population due to differences in socioeconomic status, life style, or genetic factors. The aim of this study was to investigate cancer patterns among children of Turkish descent in Germany. Methods We identified cases with Turkish names (as a proxy of Turkish descent among the 37,259 cases of childhood cancer registered in the German Childhood Cancer Registry (GCCR during 1980–2005. As it is not possible to obtain reference population data for children of Turkish descent, the distribution of cancer diagnoses was compared between cases of Turkish descent and all remaining (mainly German cases in the registry, using proportional cancer incidence ratios (PCIRs. Results The overall distribution of cancer diagnoses was similar in the two groups. The PCIRs in three diagnosis groups were increased for cases of Turkish descent: acute non-lymphocytic leukaemia (PCIR 1.23; CI (95% 1.02–1.47, Hodgkin's disease (1.34; 1.13–1.59 and Non-Hodgkin/Burkitt lymphoma (1.19; 1.02–1.39. Age, sex, and period of diagnosis showed no influence on the distribution of diagnoses. Conclusion No major differences were found in cancer patterns among cases of Turkish descent compared to all other cases in the GCCR. Slightly higher proportions of systemic malignant diseases indicate that analytical studies involving migrants may help investigating the causes of such cancers.

    Full Text Available Abstract Background Practice registry measurement provides a foundation for quality improvement, but experiences in practice are not widely reported. One setting where practice registry measurement has been implemented is the Health Resources and Services Administration's Health Disparities Cancer Collaborative (HDCC. Methods Using practice registry data from 16 community health centers participating in the HDCC, we determined the completeness of data for screening, follow-up, and treatment measures. We determined the size of the change in cancer care processes that an aggregation of practices has adequate power to detect. We modeled different ways of presenting before/after changes in cancer screening, including count and proportion data at both the individual health center and aggregate collaborative level. Results All participating health centers reported data for cancer screening, but less than a third reported data regarding timely follow-up. For individual cancers, the aggregate HDCC had adequate power to detect a 2 to 3% change in cancer screening, but only had the power to detect a change of 40% or more in the initiation of treatment. Almost every health center (98% improved cancer screening based upon count data, while fewer (77% improved cancer screening based upon proportion data. The aggregate collaborative appeared to increase breast, cervical, and colorectal cancer screening rates by 12%, 15%, and 4%, respectively (p Conclusions The aggregate HDCC registries had both adequate reporting rates and power to detect significant changes in cancer screening, but not follow-up care. Different measures provided different answers about improvements in cancer screening; more definitive evaluation would require validation of the registries. Limits to the implementation and interpretation of practice registry measurement in the HDCC highlight challenges and opportunities for local and aggregate quality improvement activities.

    Despite improved survival rates, childhood and young adult (YA) cancer survivors face elevated risks for life-threatening morbidities, especially cardiovascular complications. Our nationwide Finnish registry study investigated the purchases of cardiovascular medication from 1993 to 2011 in patients diagnosed with cancer aged below 35 years (N = 8,197) between 1993 and 2004 compared to siblings (N = 29,974) via linkage to the drug purchase registry. The cumulative incidence for purchasing cardiovascular medications was higher in childhood and YA cancer patients compared to siblings with a rising trend over time. After childhood cancer, the highest hazard ratio (HR) was found for purchasing anticoagulants (HR 19.8, 95% CI 8.5-45.9). The HRs for any cardiovascular medication (HR 7.2, 95% CI 5.1-10.1) and cardiac medication (HR 4.8, 95% CI 3.3-6.9) were markedly elevated after childhood cancer as well. Regarding YA cancer patients, the respective HRs were 2.5 (95% CI 2.0-3.2) for anticoagulants, HR 1.7 (95% CI 1.5-1.9) for any cardiovascular medication and HR 1.5 (95% CI 1.3-1.7) for cardiac medication. Among cancer patients, highest HRs for cardiovascular medication were observed after childhood acute lymphoblastic leukemia (ALL) and bone tumors (HR 10.2, 95% CI 6.8-15.5 and HR 7.4, 95% CI 4.0-13.7) and YA ALL and acute myeloid leukemia (HR 5.1, 95% CI 3.5-7.1 and HR 2.8, 95% CI 1.8-4.0). Our study demonstrated increased HRs for purchasing cardiovascular medication after early-onset cancer compared to siblings reflecting elevated cardiovascular morbidity. Thus, the implementation of long-term cardiovascular disease screening is imperative to prevent, detect and adequately treat cardiovascular late effects after cancer at a young age. PMID:26610262

    Trial registration and public accessibility of appended or published protocols of phase III randomized clinical trials (RCTs) allow comparison of reported research with essential aspects of trial design. We determined how eligibility criteria of participants specified in protocols were described in trial registries and articles of 255 cancer RCTs published in leading journals. The mean proportion of matching eligibility criteria between protocols and publications per trial (the primary endpoint) was 44.0% (95% confidence interval [CI] = 40.8% to 47.3%). Almost all discrepancies in eligibility criteria (96.7%, 95% CI = 96.1% to 97.3%) suggested to readers of articles that a broader study population was included. The mean proportion of matching eligibility criteria between protocols and registries was 72.9% (95% CI = 68.2% to 77.7%, the secondary endpoint). We conclude that there are substantial differences in eligibility criteria between trial protocols, registries and articles. Inaccurate reporting of eligibility criteria may prevent appropriate assessment of the applicability of trial results. PMID:27226519

  20. Cancer incidence in atomic bomb survivors. Part I: Use of the tumor registries in Hiroshima and Nagasaki for incidence studies

    International Nuclear Information System (INIS)

    More than 30 years ago, population-based tumor registries were established in Hiroshima and Nagasaki. This report, the first of a series of papers on cancer incidence, describes methodological aspects of the tumor registries and discusses issues of data quality in the context of the Life Span Study (LSS) cohort, the major atomic bomb survivor population. The tumor registries in Hiroshima and Nagasaki are characterized by active case ascertainment based on abstraction of medical records at area hospitals, augmented by tissue registries operational in the area and a number of clinical and pathological programs undertaken over the years among the atomic bomb survivors. Using conventional measures of quality, the Hiroshima and Nagasaki tumor registries have a death certificate-only (DCO) rate of less than 9%, a mortality/incidence (M/I) ratio of about 50%, and a histological verification (HV) rate in excess of 70%, which place these registries among the best in Japan and comparable to many established registries worldwide. All tumor registry data pertaining to the LSS population were assembled, reviewed and handled with special attention given to the quality and uniformity of data based on standardized procedures. Special studies and monitoring programs were also introduced to evaluate the quality of the tumor incidence data in the LSS. Analyses were performed to examine the quality of incidence data overall and across various substrata used for risk assessment such as age, time and radiation dose groups. No significant associations were found between radiation dose and data quality as measured by various indices. These findings warrant the use of the present tumor registry-based data for studies of cancer incidence in the atomic bomb survivors. 41 refs., 2 figs., 10 tabs

    Cancer registries (CR) are the fundamental source of objective cancer data, and thus are indispensable for the evaluation of the cancer burden and for design of effective cancer control plans. Their potential roles spread far beyond epidemiological research, from the exploration of the causes of cancer to health economics, from the evaluation of mass screening programmes to monitoring the quality and outcomes of health services, from addressing the inequalities in access to healthcare, to patients' quality of life analyses, from treatment safety to the development of biomarkers. In Europe, cancer registration is challenged by significant disparities in the quality and coverage of CRs, by insufficient harmonisation and comparability of procedures and data, by heterogeneous legislation that limits CR's abilities for networking, collaboration, and participation in research. These arise against the background of large variations in economical, regulatory, social, and cultural national contexts. Important steps have been taken at European Union (EU)-level in recent years towards mapping and understanding these challenges, identifying best practices and formulating sensible recommendations, and creating the policy frameworks and the tools for cooperation and information sharing. Yet, as cancer has now become the second cause of death in Europe, one third of the population still lacks quality cancer registration, mostly in the regions with lowest resources and health status. It is therefore imperative that the efforts to support the development of CRs continue, and that the wealth of knowledge and vision acquired in this area is transformed into action. PMID:27350787

    Full Text Available Background. Human papillomavirus (HPV is estimated to play an etiologic role in 40%-50% of penile cancers worldwide. Estimates of HPV prevalence in U.S. penile cancer cases are limited. Methods. HPV DNA was evaluated in tumor tissue from 79 invasive penile cancer patients diagnosed in 1998-2005 within the catchment areas of 7 U.S. cancer registries. HPV was genotyped using PCR-based Linear Array and INNO-LiPA assays and compared by demographic, clinical, and pathologic characteristics and survival. Histological classification was also obtained by independent pathology review. Results. HPV DNA was present in 50 of 79 (63% of invasive penile cancer cases. Sixteen viral genotypes were detected. HPV 16, found in 46% (36/79 of all cases (72% of HPV-positive cases was the most prevalent genotype followed equally by HPV 18, 33, and 45, which each comprised 5% of all cases. Multiple genotypes were detected in 18% of viral positive cases. HPV prevalence did not significantly vary by age, race/ethnicity, population size of geographic region, cancer stage, histology, grade, penile subsite, or prior cancer history. Penile cases diagnosed in more recent years were more likely to be HPV positive. Overall survival did not significantly vary by HPV status. Conclusions. The relatively high prevalence of HPV in our study population provides limited evidence of a more prominent and, possibly, increasing role of infection in penile carcinogenesis in the U.S. compared to other parts of the world.

    Cancer rates are increasing in low- and middle- income countries. There are a limited number of populationbased cancer registries in Africa and the Egyptian population-based registry in Gharbiah is one of those registries. This registry has followed the standard international registration process and methods since 1999 and has been included in Cancer Incidence in Five Continents volumes IX and X. This article illustrates the reflection of improving medical care in the geographic region of the registry and focused training on enhancing the registry data. The registry area has seen advancement in medical care and cancer diagnostic facilities during the study period. The focused training included 8 different international training sessions over 8 different years for the registrars, administrators, and directors as well as continuing on-the-job training for other registry personnel. These improvements resulted in an overall 40% increase in nonmicroscopic diagnosis of hepatocellular carcinoma, as well as 20%, 10%, and 10% increases in microscopic diagnosis of pancreatic, brain, and lung cancers, respectively, over 9 years. An overall increase of 5% to 10% in subsite diagnosis was also seen for lung, colon, brain, bladder, and breast cancers for the same 9 years. An increase of 3% in grading was seen for solid tumors while 11% was seen for lymphoma. This study showed that low- and middle- income countries can observe higher data quality for cancer registries with improvement in medical care and focused training. PMID:27028092

    Full Text Available Obtaining complete medical record information can be challenging and expensive in breast cancer studies. The current literature is limited with respect to the accuracy of self-report and factors that may influence this. We assessed the agreement between self-reported and medical record breast cancer information among women from the Ontario site of the Breast Cancer Family Registry. Women aged 20–69 years diagnosed with incident breast cancer 1996–1998 were identified from the Ontario Cancer Registry, sampled on age and family history. We calculated kappa statistics, proportion correct, sensitivity, specificity, and positive and negative predictive values and conducted unconditional logistic regression to examine whether characteristics of the women influenced agreement. The proportions of women who correctly reported having received a broad category of therapy (hormone therapy, chemotherapy, radiation, or surgery as well as sensitivity and specificity were above 90%, and the kappa statistics were above 0.80. The specific type of hormonal or chemotherapy was reported with low-to-moderate agreement. Aside from recurrence, no factors were consistently associated with agreement. Thus, most women were able to accurately report broad categories of treatment but not necessarily specific treatment types.

    Cancer survivors, the medical community, public health professionals, researchers, and policymakers all need information about newly diagnosed cancer cases and deaths to better understand and address the disease burden. CDC collects cancer data on 96% of the U.S. population through the National Program of Cancer Registries. The National Program of Cancer Registries routinely collects data on all cancer occurrences, deaths, and the types of initial treatment received by the patients, and recently CDC has made advances in its cancer surveillance activities that have direct applicability to cancer survivorship research and care. This article examines CDC's innovative uses of the National Program of Cancer Registries infrastructure and data as a recruitment source for survivorship research studies and behavioral interventions; comparative effectiveness and patient-centered outcomes research; and the collection, consolidation, and dissemination of treatment summaries for cancer survivors and their providers. This paper also discusses long-term, idealistic plans for additional data linkages and sharing among public health, providers, and the cancer survivor through innovative concepts such as patient portals and rapid-learning health care.

  11. Adjuvant Brachytherapy Removes Survival Disadvantage of Local Disease Extension in Stage IIIC Endometrial Cancer: A SEER Registry Analysis

    International Nuclear Information System (INIS)

    Purpose: To assess the role of radiotherapy (RT) in women with Stage IIIC endometrial cancer. Methods and Materials: The 17-registry Survival, Epidemiology, and End Results (SEER) database was searched for patients with lymph node-positive non-Stage IV epithelial endometrial cancer diagnosed and treated between 1988 and 1998. Two subgroups were identified: those with organ-confined Stage IIIC endometrial cancer and those with Stage IIIC endometrial cancer with direct extension of the primary tumor. RT was coded as external beam RT (EBRT) or brachytherapy (BT). Observed survival (OS) was reported with a minimum of 5 years of follow-up; the survival curves were compared using the log-rank test. Results: The therapy data revealed 611 women with Stage IIIC endometrial cancer during this period. Of these women, 51% were treated with adjuvant EBRT, 21% with EBRT and BT, and 28% with no additional RT (NAT). Of the 611 patients, 293 had organ-confined Stage IIIC endometrial cancer and 318 patients had Stage IIIC endometrial cancer with direct extension of the primary tumor. The 5-year OS rate for all patients was 40% with NAT, 56% after EBRT, and 64% after EBRT/BT. Adjuvant RT improved survival compared with NAT (p <0.001). In patients with organ-confined Stage IIIC endometrial cancer, the 5-year OS rate was 50% for NAT, 64% for EBRT, and 67% for EBRT/BT. Again, adjuvant RT contributed to improved survival compared with NAT (p = 0.02). In patients with Stage IIIC endometrial cancer and direct tumor extension, the 5-year OS rate was 34% for NAT, 47% for EBRT, and 63% for EBRT/BT. RT improved OS compared with NAT (p <0.001). Also, in this high-risk subgroup, adding BT to EBRT was superior to EBRT alone (p = 0.002). Conclusion: Women with Stage IIIC endometrial cancer receiving adjuvant EBRT and EBRT/BT had improved OS compared with patients receiving NAT. When direct extension of the primary tumor was present, the addition of BT to EBRT was even more beneficial

  14. ABRAXAS (FAM175A and Breast Cancer Susceptibility: No Evidence of Association in the Breast Cancer Family Registry.

    Directory of Open Access Journals (Sweden)

    Anne-Laure Renault

    Full Text Available Approximately half of the familial aggregation of breast cancer remains unexplained. This proportion is less for early-onset disease where familial aggregation is greater, suggesting that other susceptibility genes remain to be discovered. The majority of known breast cancer susceptibility genes are involved in the DNA double-strand break repair pathway. ABRAXAS is involved in this pathway and mutations in this gene impair BRCA1 recruitment to DNA damage foci and increase cell sensitivity to ionizing radiation. Moreover, a recurrent germline mutation was reported in Finnish high-risk breast cancer families. To determine if ABRAXAS could be a breast cancer susceptibility gene in other populations, we conducted a population-based case-control mutation screening study of the coding exons and exon/intron boundaries of ABRAXAS in the Breast Cancer Family Registry. In addition to the common variant p.Asp373Asn, sixteen distinct rare variants were identified. Although no significant difference in allele frequencies between cases and controls was observed for the identified variants, two variants, p.Gly39Val and p.Thr141Ile, were shown to diminish phosphorylation of gamma-H2AX in MCF7 human breast adenocarcinoma cells, an important biomarker of DNA double-strand breaks. Overall, likely damaging or neutral variants were evenly represented among cases and controls suggesting that rare variants in ABRAXAS may explain only a small proportion of hereditary breast cancer.

  16. Age-specific interval breast cancers in Japan. Estimation of the proper sensitivity of screening using a population-based cancer registry

    International Nuclear Information System (INIS)

    The age-specific sensitivity of a screening program was investigated using a population-based cancer registry as a source of false-negative cancer cases. A population-based screening program for breast cancer was run using either clinical breast examinations (CBE) alone or mammography combined with CBE in the Miyagi Prefecture from 1997 to 2002. Interval cancers were newly identified by linking the screening records to the population-based cancer registry to estimate the number of false-negative cases of screening program. Among 112071 women screened by mammography combined with CBE, the number of detected cancers, false-negative cases and the sensitivity were 289, 22 and 92.9%, respectively, based on the reports from participating municipalities. The number of newly found false-negative cases and corrected sensitivity when using the registry were 34 and 83.8%, respectively. In detected cancers, the sensitivity of screening by mammography combined with CBE in women ranging from 40 to 49 years of age based on a population-based cancer registry was much lower than that in women 50-59 and 60-69 years of age (40-49: 18, 71.4%, 50-59: 19, 85.8%, 60-69: 19, 87.2%). These data suggest that the accurate outcome of an evaluation of breast cancer screening must include the use of a population-based cancer registry for detecting false-negative cases. Screening by mammography combined with CBE may therefore not be sufficiently sensitive for women ranging from 40 to 49 years of age. (author)

    2014-01-01

    Full Text Available Background: An assessment of cancer incidence in population is required for prevention, early diagnosis, treatment and resource allocation. This will also guide in the formation of facilities for diagnosis, treatment, rehabilitation and follow-up for these patients. The demographic trend of cancer will help to identify common types and etiological factors. Efforts at clinical, research and administrative levels are needed to overcome this problem. Settings and Design: Present retro prospective study was conducted in regional cancer center of a tertiary care hospital. Materials and Methods: After permission from ethics committee, a retro prospective study of 1 year duration was undertaken to study the profile of cancer patients and to compare it with other cancer registries in India. Statistical Analysis: Pearson′s Chi-square test and simple linear regression were used. Statistical Package for the Social Sciences version-16 (University of Bristol information services (www.bristol.ac.uk/is/learning/resources was used. RESULTS: The overall incidence of cancer in Kashmir is on the increase and common sites of cancer are esophagus and gastroesophageal (GE junction, lung, stomach, colorectal, lymphomas, skin, laryngopharynx, acute leukemias, prostate and brain in males.In females common sites are breast, esophagus and GE junction, ovary, colorectal, stomach, lung, gallbladder, lymphomas, acute leukemias and brain. Conclusion: Cancers of esophagus, stomach and lungs have a high incidence both in men and women in Kashmir. Future studies on sources and types of environmental pollution and exposures in relation to these cancers may improve our understanding of risk factors held responsible for causation of these malignancies in this region. This will help in the allocation of available resources for prevention and treatment strategies.

    Of 1,486,984 new cancers registered in the Czech Cancer Registry in 1976-2005, 290,312 (19.5%) were multiple malignant neoplasms (MMNs), of which there were 65,292 primary and 89,796 subsequent cases in men and 59,970 primary and 75,254 subsequent cases in women. The duplicities were higher in women, and the triplicities and others (3–6 MMNs) were higher in men. The most frequent diagnoses were the primary cancers of skin, gastrointestinal and urinary tract, male genital organs, respiratory tract in men, and cancers of skin, breast, female genital organs, and gastrointestinal tract in women. The analysis of the early and advanced clinical stages shows that the number of subsequent advanced stages increased after primary advanced stages. Their time-age-space distributions visualized maps of MMNs in 14 Czech regions. These results support the improvement of algorithms of dispensary care for the early detection of the subsequent neoplasms. PMID:23936674

    2013-01-01

    Objectives: Testicular cancer affects mainly men below the age of 50. An association with occupation and social status has been suggested but risk factors are not well understood. A registry-based case-control study focusing on occupation was performed in Germany. Methods: All 348 testicular cancer cases with available gainful occupational information registered between 2000 and 2005; as well as 564 suitable controls (from a pool of other cancers) were drawn from the Cancer Registry of Rhineland-Palatinate. Unconditional logistic regression was used to compute odds ratios (OR) and associated 95% confidence intervals (CI). Results: Slightly elevated OR were observed for technicians and related professionals (OR 1.62, 95% CI 1.00–2.63) and for clerical support workers (OR 1.71, 95% CI 1.14–2.56). This increase was highest in the age group 20–50 for technicians (OR 2.02, 95% CI 1.23–3.33) and clerks (OR 2.00, 95% CI 1.30–3.09), respectively. An association with testicular cancer was observed for no other occupation. Conclusion: An increased risk of testicular cancer was observed for technicians and related professionals and clerical support workers. This could be related to socioeconomic status or sedentary life style, two factors that were identified in previous studies. While the feasibility of a purely registry-based study was shown, missing occupational data and the choice of cancer controls represent challenges to the validity of this approach. PMID:24265602

    Full Text Available Adenosquamous carcinoma (ASC is a rare disease involving various organs, yet there are no large-scale population-based comparative studies on ASC among different organs.The incidence and overall survival of ASC among various organs in cases diagnosed in Taiwan from January 1, 2003 to December 31, 2010 were calculated and compared using data from the Taiwan Cancer Registry (TCR. The various organs were classified and divided into three different systems: the female reproductive, respiratory, and alimentary systems. Survival analysis were also compared among 30,850 patients diagnosed as ASC, adenocarcinoma (AC or squamous cell carcinoma (SCC in organs with frequent ASC.During the study period, a total of 576 ASC cases were diagnosed in Taiwan. The most common primary system was respiratory (73.8%, followed by alimentary (16.2% and female reproductive (10%. The overall survival were significantly higher for cases involving the female reproductive system, followed by the respiratory and alimentary systems (P = 0.016. The median overall survival were worse in males than females for cases involving the respiratory system (22.4 vs. 31.8 months, P = 0.044. Multivariate analysis showed that age ≧ 65, more advanced T and N categories were independent unfavorable prognostic factors of overall survival in ASC. ASC histology is an independent unfavorable prognostic factor compared with AC and SCC.ASC at an old age and more advanced T and N categories were found to be associated with a poor prognosis.

    Background Registration of haematological malignancies presents specific challenges, and a wide range of data is required to ensure case ascertainment and proper classification of these diseases. We studied the data quality of myeloproliferative and myelodysplastic neoplasms in the Finnish Cancer Registry (FCR), comparing information with hospital discharges. Material and methods Hospital discharges (HILMO) in 2007-2013 including diagnostic codes of myeloproliferative and myelodysplastic neoplasms were extracted. Patients were individually linked to the FCR database for all haematological malignancies registered in 1953-2013. Coverage and accuracy of the FCR and agreement between registers was estimated. Results In total 5289 individuals were retrieved from two registers. Of these, 1406 were common, 1080 only found in the FCR and 2803 only in the HILMO. Coverage of myeloproliferative and myelodysplastic neoplasms in the FCR was 47.0% (95% CI 45.7-48.4%). Almost one quarter of the registrations in the FCR was based on a death certificate only. The accuracy of diagnosis was 51.4% (95% CI 49.4-53.3%), but it varied substantially by disease category. Kappa statistic for agreement between registers was excellent (0.83, 95% CI 0.80-0.85) for common cases. 7.6% of cases in the HILMO was registered as leukaemias in the FCR. Conclusions More than half of the patients found in the HILMO were entirely missing from the FCR. However, some of the diagnoses in HILMO may be preliminary and this represents the maximal number of missing cases. Cancer registers benefit from supplementary data sources, such as hospital discharges, to increase coverage and accuracy of register data on haematological malignancies. PMID:26767306

    Background and Aim Because most colorectal cancer patients survive beyond five years, understanding quality of life among these long-term survivors is essential to providing comprehensive survivor care. We sought to identify personal characteristics associated with reported quality of life in colorectal cancer survivors, and sub-groups of survivors potentially vulnerable to very low quality of life. Methods We assessed quality of life using the Veterans RAND 12-item Health Survey within a population-based sample of 1,021 colorectal cancer survivors in the Seattle Colorectal Cancer Family Registry, approximately 5 years post-diagnosis. In this case-only study, mean physical component summary scores and mental component summary scores were examined with linear regression. To identify survivors with substantially reduced ability to complete daily tasks, logistic regression was used to estimate odds ratios for “very low” summary scores, defined as a score in the lowest decile of the reference US population. All cases were followed for vital status following QoL assessment, and mortality was analyzed with Cox proportional hazards regression. Results Lower mean physical component summary score was associated with older age, female sex, obesity, smoking, and diabetes or other co-morbidity; lower mean mental component summary score was associated with younger age and female sex. Higher odds of very low physical component summary score was associated with older age, obesity, less education, smoking, co-morbidities, and later stage at diagnosis; smoking was associated with higher odds of very low mental component summary score. A very low physical component score was associated with higher risk of mortality (hazard ratio (95% confidence interval): 3.97 (2.95–5.34)). Conclusions Our results suggest that identifiable sub-groups of survivors are vulnerable to very low physical components of quality of life, decrements that may represent meaningful impairment in completing

    Objective HIV-infected people have elevated risk for some cancers. Changing incidence of these cancers over time may reflect changes in three factors: HIV population demographic structure (e.g. age distribution), general population (background) cancer rates, and HIV-associated relative risks. We assessed the contributions of these factors to time trends for 10 cancers during 1996–2010. Design Population-based registry linkage study. Methods We applied Poisson models to data from the U.S. HIV/AIDS Cancer Match Study to estimate annual percent changes (APCs) in incidence rates of AIDS-defining cancers (ADCs: Kaposi sarcoma (KS), non-Hodgkin lymphoma (NHL), and cervical cancer) and 7 non-AIDS-defining cancers (NADCs). We evaluated HIV-infected cancer trends with and without adjustment for demographics, trends in background rates, and trends in standardized incidence ratios (SIRs, to capture relative risk). Results Cancer rates among HIV-infected people rose over time for anal (APC 3.8%), liver (8.5%), and prostate (9.8%) cancers, but declined for KS (1996–2000: −29.3%; 2000–2010: −7.8%), NHL (1996–2003: −15.7%; 2003–2010: −5.5%), cervical cancer (−11.1%), Hodgkin lymphoma (HL, −4.0%), and lung cancer (−2.8%). Breast and colorectal cancer incidence did not change over time. Based on comparison to adjusted models, changing demographics contributed to trends for KS and breast, colorectal, liver, lung, and prostate cancers (all p<0.01). Trends in background rates were notable for liver (APC 5.6%) and lung (−3.2%) cancers. SIRs declined for ADCs, HL (APC −3.2%), and lung cancer (−4.4%). Conclusions Demographic shifts influenced several cancer trends among HIV-infected individuals. Falling relative risks largely explained ADC declines, while background incidence contributed to some NADC trends. PMID:24300545

  14. Rectal cancer treatment and outcome in the elderly: an audit based on the Swedish rectal cancer registry 1995–2004

    International Nuclear Information System (INIS)

    Limited information is available regarding the effect of age on choice of surgical and oncological treatment for rectal cancer. The objective of this study was to assess the influence of age on treatment and outcome of rectal cancer. We utilized data in the Swedish Rectal Cancer Registry (SRCR) from patients treated for rectal cancer in Sweden in 1995–2004. A total of 15,104 patients with rectal cancer were identified, 42.4% of whom were 75 years or older. Patients ≥75 years were less likely to have distant metastases than younger patients (14.8% vs. 17.8%, P < 0.001), and underwent abdominal tumor resection less frequently (68.5% vs. 84.4%, P < 0.001). Of 11,725 patients with abdominal tumor resection (anterior resection [AR], abdominoperineal excision [APE], and Hartmann's procedure [HA]), 37.4% were ≥75 years. Curative surgery was registered for 85.0% of patients ≥ 75 years and for 83.9% of patients < 75 years, P = 0.11. Choice of abdominal operation differed significantly between the two age groups for both curative and non-curative surgery, The frequency of APE was similar in both age groups (29.5% vs. 28.6%), but patients ≥75 years were more likely to have HA (16.9% vs. 4.9%) and less likely to have preoperative radiotherapy (34.3vs. 67.2%, P < 0.001). The relative survival rate at five years for all patients treated with curative intent was 73% (70–75%) for patients ≥75 years and 78% (77–79%) for patients < 75 years of age. Local recurrence rate was 9% (8–11%) for older and 8% (7–9%) for younger patients. Treatment of rectal cancer is influenced by patient's age. Future studies should include younger and older patients alike to reveal whether or not age-related differences are purposive. Local recurrence following surgery for low tumors and quality of life aspects deserve particular attention

    Despite increasing numbers of women availing themselves of assisted reproductive technology (ART), effects on cancer risk remain unresolved. Given hormonal exposures, breast cancer risk is of particular concern. The aim of this study is to investigate breast cancer risk amongst women giving birth following ART as compared to that amongst women who gave birth without ART. Data on all women who gave birth in Norway with or without ART, between 1984 and 2010 was obtained from the Medical Birth Registry of Norway (MBRN). 808 834 women eligible for study were linked to the Cancer Registry of Norway. Cox proportional hazards model computed relative risk of breast cancer between the two groups, adjusting for age, parity, age at first birth, calendar period and region of residence. A total of 8037 women were diagnosed with breast cancer during the study period, 138 ART women and 7899 unexposed. Total follow-up time was 12 401 121 person-years (median 16.0), median age at entry was 32.5 years (range18.6-49.9) for ART women and 26.3 (range 10.5-54.6) for women without ART. Women exposed to ART had an elevated risk of breast cancer (adjusted HR 1.20, 95% CI 1.01-1.42). Subgroup analyses resulted in an HR of 1.30 (95% CI 1.07-1.57) for women treated with IVF and 1.35 (95 % CI 1.07-1.71) for women with follow-up >10 years, compared with controls. Our findings of increased risk in the study population, warrant continued monitoring of women treated with ART as this population advances into more typical cancer age ranges. PMID:25042052

  16. Meat intake, cooking methods, dietary carcinogens, and colorectal cancer risk: findings from the Colorectal Cancer Family Registry

    International Nuclear Information System (INIS)

    Diets high in red meat and processed meats are established colorectal cancer (CRC) risk factors. However, it is still not well understood what explains this association. We conducted comprehensive analyses of CRC risk and red meat and poultry intakes, taking into account cooking methods, level of doneness, estimated intakes of heterocyclic amines (HCAs) that accumulate during meat cooking, tumor location, and tumor mismatch repair proficiency (MMR) status. We analyzed food frequency and portion size data including a meat cooking module for 3364 CRC cases, 1806 unaffected siblings, 136 unaffected spouses, and 1620 unaffected population-based controls, recruited into the CRC Family Registry. Odds ratios (OR) and 95% confidence intervals (CI) for nutrient density variables were estimated using generalized estimating equations. We found no evidence of an association between total nonprocessed red meat or total processed meat and CRC risk. Our main finding was a positive association with CRC for pan-fried beefsteak (Ptrend < 0.001), which was stronger among MMR deficient cases (heterogeneity P = 0.059). Other worth noting associations, of borderline statistical significance after multiple testing correction, were a positive association between diets high in oven-broiled short ribs or spareribs and CRC risk (Ptrend = 0.002), which was also stronger among MMR-deficient cases, and an inverse association with grilled hamburgers (Ptrend = 0.002). Our results support the role of specific meat types and cooking practices as possible sources of human carcinogens relevant for CRC risk

    Records of female breast cancer patients were selected from a clinical cancer registry and separated into three cohorts according to HER2-status (human epidermal growth factor receptor 2) and treatment with or without Trastuzumab (a humanized monoclonal antibody). Propensity score matching was used to balance the cohorts. Afterwards, documented information about disease events (recurrence of cancer, metastases, remission of local/regional recurrences, remission of metastases and death) found in the dataset was leveraged to calculate the annual transition probabilities for every cohort.

  18. Contributions of cytology examination and methods in lung cancer diagnostic

    International Nuclear Information System (INIS)

    Background. Lung cancer (LC) is still the leading cause of cancer death according to published data worldwide and confirmed also by the data obtained from the central Cancer Registry of Slovenia. Early detection of LC has an important impact on the long-term survival rate of the patients. In spite of a great advance in imaging technology for a better visualization and early detection of the neoplasms and a variety of screening tests, only cytopathology examination finally define the neoplastic lesion. Methods. To evaluate the contribution of cytology examination in the diagnosis of LC we studied the cytology diagnoses, comparing them with histology reports in patients, who underwent the diagnostic procedure under suspicion of the LC during last 2 years. Results. Of a total 772 patients, in 241 patients cancer was microscopically confirmed. The most frequent diagnoses were adenocarcinoma (36.9%), squamous cell carcinoma (26.6%), and small cell carcinoma (SCLC) (12.9%). There were 22% of neoplasms classified as non-small cell carcinomas (NSCLC). From the clinician point of view considering the therapy it is very important to distinguish NSCLC from SCLC. And in our study the cytology-histology correlation between these two major types of carcinoma was almost 100%. Based only on cytology, 68 (28.2%) patients received microscopic diagnosis of malignoma, and the specimens for this group of patients were obtained mostly from transbronchial or transthoracic fine needle aspiration biopsies. Conclusions. Cytology is of great diagnostic value, a reliable and relatively non-invasive method for patients. Cytology specimens should be taken in cases where it is not possible to obtain samples for histology. (author)

    Little is known about the incidence patterns of hematologic malignancies in Sub-Saharan Africa, including South Africa. We estimated incidence rates of pathology-confirmed adult cases of leukemia, myeloma and related diseases (myeloma), Hodgkin lymphoma (HL), and non-Hodgkin lymphoma (NHL) reported to the National Cancer Registry of South Africa (NCR) between 2000 and2006, by age, gender, and population group (Black, White, Coloured, Asian/Indian). Gender-specific age-standardized rates were calculated overall and by population group and incidence rate ratios (IRRs) were estimated using Poisson regression models. Between 2000 and 2006, there were 14662 cases of leukemia, myeloma, HL, and NHL reported to the registry. Incidence rates of reported hematologic malignancies were generally 20-50% higher among males than females. Our analyses suggested marked differences in the rates of reported hematologic malignancies by population group which were most pronounced when comparing the White versus Black population groups (IRRs ranging from 1.6 for myeloma to 3.8 for HL for males and females combined). Challenges related to diagnosis and reporting of cancers may play a role in the patterns observed by population group while the set-up of the NCR (pathology-based) could lead to some degree of under-ascertainment in all groups. This is the first country-wide report of the incidence of hematologic malignancies in South Africa. Despite challenges, it is important to analyze and report available national cancer incidence data to raise awareness of the cancer burden and to characterize patterns by demographic characteristics so as ultimately to improve the provision of cancer-related health care.

    Drinking alcohol and smoking tobacco are major modifiable risk factors for cancer. However, little is known about whether these modifiable factors of cancer survivors are associated with subsequent primary cancer (SPC) incidence, regardless of the first cancer sites. 27,762 eligible cancer survivors diagnosed between 1985 and 2007 were investigated for SPC until the end of 2008, using hospital-based and population-based cancer registries. The association between drinking, smoking and combined drinking and smoking (interaction) at the time of the first cancer diagnosis and incidence of SPCs (i.e., all SPCs, alcohol-related, smoking-related and specific SPCs) was estimated by Poisson regression. Compared with never-drinker/never-smoker, the categories ever-drinker/ever-smoker, current-drinker/current-smoker and heavy-drinker/heavy-smoker had 43-108%, 51-126% and 167-299% higher risk for all, alcohol-related and tobacco-related SPCs, respectively. The interaction of drinking and smoking had significantly high incidence rate ratios (IRRs) for SPCs among ever-drinker/ever-smoker and current-drinker/current-smoker, although ever drinking did not show a significant risk. Ever-drinker/ever-smoker had also significantly higher IRRs for esophageal and lung SPCs than never-drinker/never-smoker. Among comprehensive cancer survivors, ever and current drinkers only had a SPC risk when combined with smoking, while ever and current smokers had a SPC risk regardless of drinking status. Heavy drinking and heavy smoking were considered to be independent additive SPC risk factors. To reduce SPC incidence, it may be necessary (i) to reduce or stop alcohol use, (ii) to stop tobacco smoking and (iii) dual users, especially heavy users, should be treated as a high-risk population for behavioral-change intervention.

    Both alcohol abuse and liver cirrhosis are known risk factors for various cancers. This article was aimed to assess the long-term risk of malignancies among patients with severe alcoholic liver disease (ALD), i.e., alcoholic liver cirrhosis and alcoholic hepatitis. A cohort of 8,796 male and 3,077 female ALD patients from 1996 to 2012 was identified from the Finnish National Hospital Discharge Register. This nationwide cohort was combined with the data from the Finnish Cancer Registry for incidence of malignancies during the years 1996-2013. The cancer cases diagnosed were compared with the number of cancers in the general population. The number of malignancies in our cohort was 1,052 vs. 368 expected. There was statistically significant excess of cancers of the liver, (standardized incidence ratio [SIR] 59.20; 95% CI 53.11-65.61), pancreas (SIR 3.71; 95% CI 2.72-4.94), pharynx (SIR 9.25; 95% CI 6.05-13.56), mouth (SIR 8.31; 95% CI 4.84-13,29), oesophagus (SIR 7.92; 95% CI 5.49-11.07), tongue (SIR 7,21; 95% CI 3.60-12.89), larynx (SIR 5.20; 95% CI 2.77-8.89), lung (SIR 2.77; 95% CI 2.27-3.32), stomach (SIR 2.76; 95% CI 1.79-4.07), kidney (SIR 2.69; 95% CI 1.84-3.79) and colon (SIR 2.33; 95% CI 1.70-3.11). There was no decreased risk of any cancer among ALD patients. Severe ALD is associated with markedly increased risk of malignancies. The risk is especially high for hepatocellular carcinoma, but also significantly increased for cancers of the upper aerodigestive tract, pancreas and kidneys, and warrants cancer surveillance in selected cases.

    Full Text Available Abstract Background The Danish Veterinary Cancer Registry (DVCR was established in May 2005 to gather information about neoplasms in the Danish dog and cat populations. Practitioners from more than 60 clinics throughout Denmark have submitted data on these species. The objectives of the current study were, with a special focus on mast cell tumours (MCT to investigate the occurrence, gender distribution, biological behaviour, locations, types, the diagnostic method used and treatment of skin neoplasms in dogs based on information reported to the DVCR. Methods From May 15th 2005 through February 29th 2008, reports on a total of 1,768 canine cases of neoplasia in the skin, subcutis or adnexa were submitted. Of these, 765 cases (43% were confirmed by cytology or histopathology. Results The majority of dogs had a benign neoplasm (66% while 21% were cases of malignant neoplasia. The most commonly encountered malignant neoplasms were MCT and soft tissue sarcomas and for benign neoplasms, lipomas and histiocytomas were the most common. The location of the neoplasms were primarily in the cutis, subcutis or in the perianal region. The occurrence, gender distribution, biological behaviour and location of canine skin neoplasias in Denmark were similar to earlier reports, although some national variations occurred. A correlation between grade of MCT and the proportion of cases treated surgically was observed. Conclusions Population based cancer registries like the DVCR are of importance in the collection of non-selected primary information about occurrence and distribution of neoplasms. The DVCR provides detailed information on cases of skin neoplasms in dogs and may serve as a platform for the study of sub-sets of neoplastic diseases (e.g. MCT or subgroups of the canine population (e.g. a specific breed.

    Both individual patient treatment and cancer registries depend on adequate histopathology reports. To ensure the quality of these reports, professional organizations have published guidelines on minimum data sets for various cancer types. Norway has a population of 4.6 million, and all individuals have a unique identification number. As required by law, relevant information on cancer is submitted to the Cancer Registry of Norway. A closed, national health data network has been established facilitating electronic transferal between various institutions. The Cancer Registry and the Norwegian Society for Pathology have jointly established a nationwide project to (i) develop standardized templates in database format for histopathology reports on cancer resection specimens and (ii) develop an Extensible Markup Language (XML) standard to facilitate future electronic transfer of cancer reports from hospitals to the Cancer Registry. A minimum data set template for reporting colorectal carcinoma resection specimens and the Extensible Markup Language standard have been established. The template is based on international guidelines and classification systems. For most key parameters, pull-down menus with predefined alternatives have been constructed. The template is fully integrated into software being used by all pathology laboratories in Norway. Since the introduction of the template in April 2005, the template had been used for reporting 430 (93%) of 462 colorectal resections at 2 pilot laboratories (Akershus University Hospital [Lørenskog, Norway] and Stavanger, University Hospital [Stavanger, Norway]), demonstrating that high and consistent quality can be ascertained. Pathologists have found the template both time saving and user friendly. The template is now gradually implemented nationwide. PMID:18187180

Methods: A retrospective, descriptive epidemiological analysis was conducted of all the corpus uteri cancer cases recorded in the Saudi Cancer Registry between January 2001 and December 2008. The statistical analyses were performed using descriptive statistics, analysis of variance, Poisson regression, and a simple linear model. Results: A total of 1,060 corpus uteri cancer cases were included. Women aged 60–74 years of age were most affected by the disease. The region of Riyadh in Saudi Arabia had the highest overall ASIR, at 4.4 cases per 100,000 female patients, followed by the eastern region, at 4.2, and Makkah, at 3.7. Jazan, Najran, and Qassim had the lowest average ASIRs, ranging from 0.8 to 1.4. A Poisson regression model using Jazan as the reference revealed that the corpus uteri cancer incidence rate ratio was significantly higher for the regions of Makkah, at 16.5 times (95% confidence interval [CI]: 8.0–23.0, followed by Riyadh, at 16.0 times (95% CI: 9.0–22.0, and the eastern region, at 9.9 times (95% CI: 5.6–17.6. The northern region experienced the highest changes in ASIRs of corpus uteri cancer among female Saudi patients between 2001 and 2008. Conclusion: There was a slight increase in the crude incidence rates and ASIRs for corpus uteri cancer in Saudi Arabia between 2001 and 2008. Older Saudi women were most affected by the disease.

    Full Text Available BACKGROUND: It is not known whether socioeconomic disparities affect the detection of breast cancer in Asian countries where the incidence of breast cancer is a rising trend. In this study, we explore the socioeconomic profiles of women and the stage of the disease at the time of diagnosis in breast cancer patients aged 40 or over in Hong Kong. METHOD: During the period 2008 to 2011, 5393 breast cancer patients registered with the Hong Kong Breast Cancer Registry. Participants and their clinicians were asked to complete standardised questionnaires including patient socio-demographics, health history and risk factors, the course of the disease, post-treatment physical discomfort and psychosocial impact, follow-up recurrence and survival status. RESULTS: Monthly household incomes, educational levels and the practice of regular screening are independently associated with the stage of the disease at diagnosis. Higher socioeconomic status and a higher educational level were associated with an earlier stage of the disease at the time of diagnosis. Yearly clinical examinations, ultrasound and mammographic screening every 2 to 3 years were significantly associated with the earlier detection of breast cancer. CONCLUSION: There were socioeconomic disparities among Hong Kong women who were found to have breast cancer. Population-based screening policies, including raising awareness among women at risk, should be implemented.

    Breast cancer screening is central to early breast cancer detection. Identifying and monitoring process measures for screening is a focus of the National Cancer Institute's Population-based Research Optimizing Screening through Personalized Regimens (PROSPR) initiative, which requires participating centers to report structured data across the cancer screening continuum. We evaluate the accuracy of automated information extraction of imaging findings from radiology reports, which are available as unstructured text. We present prevalence estimates of imaging findings for breast imaging received by women who obtained care in a primary care network participating in PROSPR (n = 139,953 radiology reports) and compared automatically extracted data elements to a "gold standard" based on manual review for a validation sample of 941 randomly selected radiology reports, including mammograms, digital breast tomosynthesis, ultrasound, and magnetic resonance imaging (MRI). The prevalence of imaging findings vary by data element and modality (e.g., suspicious calcification noted in 2.6% of screening mammograms, 12.1% of diagnostic mammograms, and 9.4% of tomosynthesis exams). In the validation sample, the accuracy of identifying imaging findings, including suspicious calcifications, masses, and architectural distortion (on mammogram and tomosynthesis); masses, cysts, non-mass enhancement, and enhancing foci (on MRI); and masses and cysts (on ultrasound), range from 0.8 to1.0 for recall, precision, and F-measure. Information extraction tools can be used for accurate documentation of imaging findings as structured data elements from text reports for a variety of breast imaging modalities. These data can be used to populate screening registries to help elucidate more effective breast cancer screening processes. PMID:25561069

    Net survival, the survival which might occur if cancer was the only cause of death, is a major epidemiological indicator required for international or temporal comparisons. Recent findings have shown that all classical methods used for routine estimation of net survival from cancer-registry data, sometimes called "relative-survival methods," provide biased estimates. Meanwhile, an unbiased estimator, the Pohar-Perme estimator (PPE), was recently proposed. Using real data, we investigated the magnitude of the errors made by four "relative-survival" methods (Ederer I, Hakulinen, Ederer II and a univariable regression model) vs. PPE as reference and examined the influence of time of follow-up, cancer prognosis, and age on the errors made. The data concerned seven cancer sites (2,51,316 cases) collected by FRANCIM cancer registries. Net survivals were estimated at 5, 10 and 15 years postdiagnosis. At 5 years, the errors were generally small. At 10 years, in good-prognosis cancers, the errors made in nonstandardized estimates with all classical methods were generally great (+2.7 to +9% points in prostate cancer) and increased in age-class estimations (vs. 5-year ones). At 15 years, in bad- or average-prognosis cancers, the errors were often substantial whatever the nature of the estimation. In good-prognosis cancers, the errors in nonstandardized estimates of all classical methods were great and sometimes very important. With all classical methods, great errors occurred in age-class estimates resulting in errors in age-standardized estimates (+0.4 to +3.2% points in breast cancer). In estimating net survival, cancer registries should abandon all classical methods and adopt the new Pohar-Perme estimator. PMID:22961565

    Despite availability of guidelines for lung cancer care, variations in lung cancer care among the elderly exist across the nation and are a cause for concern in rural and medically underserved areas. Therefore, the purpose of this study was to evaluate the patterns of lung cancer care and associated health outcomes among elderly residing in a rural and medically underserved area. The authors identified 1924 elderly lung cancer patients from the West Virginia Cancer Registry-Medicare linked database (2002-2007) and categorized them by receipt of guideline-concordant (appropriate and timely) care using guidelines from the American College of Chest Physicians, British Thoracic Society, and the RAND Corporation. Hierarchical generalized logistic models were constructed to identify variables associated with receipt of guideline-concordant care. Kaplan-Meier analysis and log-rank test were used to compare 3-year survival outcomes. Multivariate Cox proportional hazards models were constructed to estimate lung cancer mortality risk associated with nonreceipt of guideline-concordant care. Although guideline-concordant appropriate care was received by fewer than half of all patients (46.5%), of those receiving care, 78.7% received it in a timely manner. Delays in diagnosis and treatment varied significantly. Survival outcomes significantly improved with appropriate care (799 vs. 366 days; P≤0.05), but did not improve with timely care. This study highlights the critical need to address disparities in receipt of guideline-concordant lung cancer care among the elderly residing in rural and medically underserved areas. Although lung cancer diagnostic and management services are covered under the Medicare program, underutilization of these services is a concern. (Population Health Management 2016;19:109-119).

    Background Surgical wounds in cancer patients have a relatively high dehiscence rate. Although colon cancer resections are performed so as to include macroscopically non-involved tissues, some cancer cells can be present in the line of transection. The local healing process may facilitate proliferation of these localized cancer cells and the high cytokine concentration within the healing wound may also attract cancer cells from distant sites to migrate into the wound area.

    Introduction Percent mammographic density (PMD) is a strong and highly heritable risk factor for breast cancer. Studies of the role of PMD in familial breast cancer may require controls, such as the sisters of cases, selected from the same 'risk set' as the cases. The use of sister controls would allow control for factors that have been shown to influence risk of breast cancer such as race/ethnicity, socioeconomic status and a family history of breast cancer, but may introduce 'overmatching' ...

    The aim of our retrospective study was to analyze distribution of histological types, age of patients and hormonal dependency of breast cancer cases in the period 1980-2000 using computer database "Thanatos". This period was divided with regard to the war into a pre-war (1980-1990), war (1991-1995) and post-war period (1996-2000). We also paid attention to the Chernobyl accident (pre-Chernobyl from 1980-1986 and post-Chernobyl from 1987-2000). Special attention was focused on the period during the war mainly due to the fact that very little data exist in literature dealing with the war as a stress factor that may have induced and promoted carcinogenesis. During this twenty-one year period 2296 patients were diagnosed with breast cancer. In the female population of 2274, 2228 (98%) of these were ductal and only 46 (2%) were invasive lobular carcinomas. In all of the male cases (22) the cancer was pathohistologically verified as the invasive ductal type. The male:female ratio was 1:103. Comparing the pre-war and war periods we found a more than double increase in the male:female ratio (from 1:131 to 1:66). We observed similar results when we looked at the period after the Chernobyl incident where the ratio increased from 1:139 to 1:79. When we analyzed the distribution of histological types we found a significant increase in lobular carcinomas during the post-war period, from 1.1% to 5.5%; this increase was less significant for the post-Chernobyl period (1.0% to 3.3%). The average age of the patients with invasive ductal carcinomas increased from 56.7 yrs during the pre-war period to 59.7 yrs during the war and finally to 61.1 yrs during the post-war period. The average age of males with breast cancer decreased from 63.6 and 63.5 during the pre-war and war periods to 58.8 yrs during the post-war period. These results suggest that the war could have influenced the shift in the age of occurrence of breast cancer in both sexes appearing in younger males and in females

  17. The epidemiology of gastrointestinal stromal tumors in Taiwan, 1998–2008: a nation-wide cancer registry-based study

    International Nuclear Information System (INIS)

    To investigate the incidence of gastrointestinal stromal tumors (GISTs) in Taiwan and the impact of imatinib on the overall survival (OS) of GIST patients. GISTs were identified from the Taiwan Cancer Registry (TCR) from 1998 to 2008. The age-adjusted incidence rates and the observed OS rates were calculated. Cox proportional hazards models were applied to examine the mortality risk in three time periods (1998–2001, 2002–2004, 2005–2008) according to the application and availability of imatinib. From 1998 to 2008, 2,986 GISTs were diagnosed in Taiwan. The incidence increased from 1.13 per 100,000 in 1998 to 1.97 per 100,000 in 2008. The most common sites were stomach (47-59%), small intestine (31-38%), and colon/rectum (6-9%). The 5-year observed OS was 66.5% (60.3% for men, 74.2% for women, P < .0001). GISTs in the stomach had a better 5-year observed OS (69.4%) than those in the small intestine (65.1%) (P < .0001). The outcome of GIST improved significantly after the more widespread use of imatinib; the 5-year observed OS increased from 58.9% during 1998–2001 to 70.2% during 2005–2008 (P < .0001). Younger age, female sex, stomach location, and later diagnostic years were independent predictors of a better survival. The incidence of GIST has been increasing in Taiwan, partially due to the advancement of diagnostic technology/method and the increased awareness by physicians. The outcome of GIST has improved significantly with the availability and the wider use of imatinib

    2016-01-01

    Background Race, gender and socioeconomic disparities have been suggested to adversely influence stage at presentation, treatment options and outcomes in patients with cancer. Underserved minorities and those with a low socioeconomic status (SES) present with more advanced disease and have worse outcomes for differentiated thyroid cancer, but this relationship has never been evaluated for medullary thyroid cancer (MTC). Methods We used the California Cancer Registry (CCR) to evaluate disparities in the presentation, treatment and outcomes of patients diagnosed with MTC. Results We identified 634 patients with MTC diagnosed between 1988 and 2011. Almost everyone (85%) underwent thyroidectomy with 50% having a central lymph node dissection (CLND). There were no statistically significant differences by age, race or SES in mean tumor size or the proportion of patients diagnosed with localized disease, but men were diagnosed with larger tumors than women and were less likely to be diagnosed at a localized stage. Younger patients and women were more likely to be treated with a thyroidectomy. There were no statistically significant differences in surgical treatment by race or SES. Patients in the highest SES category had a better overall survival, but not disease specific survival, than those in the lowest SES (HR =0.3, CI =0.1–0.7). Patients treated with thyroidectomy had a better overall and cause specific survival, but the effect of CLND was not statistically significant after adjustment for other factors. Conclusions In MTC, we did not find that race, gender or SES influenced the presentation, treatment or outcomes of patients with MTC. Men with MTC present with larger tumors and are less likely to have localized disease. Half of the MTC patients in California do not undergo a CLND at the time of thyroidectomy, which may suggest a lack appropriate care across a range of healthcare systems. PMID:27563561

    The purpose of this study was to describe and quantify procedures and methods that maximized the efficiency of the Gharbiah Cancer Registry (GPCR), the only population-based cancer registry in Egypt. The procedures and measures included a locally-developed software program to translate names from Arabic to English, a new national ID number for demographic and occupational information, and linkage of cancer cases to new electronic mortality records of the Ministry of Health. Data was compiled from the 34,058 cases from the registry for the years 1999-2007. Cases and registry variables about demographic and clinical information were reviewed by year to assess trends associated with each new method or procedure during the study period. The introduction of the name translation software in conjunction with other demographic variables increased the identification of detected duplicates from 23.4% to 78.1%. Use of the national ID increased the proportion of cases with occupation information from 27% to 89%. Records with complete mortality information increased from 18% to 43%. Proportion of cases that came from death certificate only, decreased from 9.8% to 4.7%. Overall, the study revealed that introducing and utilizing local and culture-specific methodological changes, software, and electronic non-cancer databases had a significant impact on data quality and completeness. This study may have translational implications for improving the quality of cancer registries in LMICs considering the emerging advances in electronic databases and utilization of health software and computerization of data.

    Full Text Available Background: There is deficit of data from India on elderly patients with cancer. Comprehensive geriatric assessment may lead to a better decision making capacity in this population. However, routine implementation of such assessment is resource consuming. Aim: The aim of this study was to determine the patterns of care in elderly patients treated at a tertiary rural cancer center in India. Materials And Methods: All patients with age 70 or above with solid tumors without any definitive treatment prior to the registration at our center and registered between 01/01/2010 and 31/12/2011 were selected for this study. The baseline demographic pattern and the pattern of care of treatment were analyzed. SPSS version 16 (IBM Inc, Armonk, New York, U.S. was used for analysis. Descriptive data are provided. Results: A total of 761 patients were evaluable subject to the aforementioned inclusion criteria. The median age of this cohort was 75 years (70-95 years. The most frequent primary sites of malignancies in 451 males were head neck (32.4%, lung (23.3% and gastrointestinal (23.3%. In 310 females, the most common sites were head neck (31.6%, gynecological (18.4% and gastrointestinal (24.5%. 228 (30% of the patients had localized disease, 376 (49.4% had loco-regionally advanced disease and 145 (19.1% had distant metastases at presentation. 334 (46.32% of patients were treated with curative intent. On logistic regression analysis the factors that predicted use of curative intent treatment were age <75 years, performance status 0-1, primary site and clinical extent of disease. Conclusion: Routine comprehensive geriatric assessment needs to be implemented in our setting as almost 50% of our geriatric patients undergo curative intent treatment.

    Background Randomized controlled trials evaluating biological therapy have shown improvements in survival from metastatic colorectal cancer (mCRC). Subjects in the trials represent a selected proportion of mCRC patients. We have the potential to assess the impact of biological therapy on mCRC outcomes, particularly the effect of bevacizumab, from a population-based clinical registry by comparing two time cohorts with differences in therapy accessibility. Material and methods A retrospective cohort study was performed by analyzing the South Australian (SA) mCRC registry data based on diagnosis in two time periods: 1 February 2006-31 May 2009 (Cohort A) versus 1 June 2009-30 June 2014 (Cohort B). The demarcation for these cohorts was chosen to reflect the change in accessibility of bevacizumab from July 2009. Results Between February 2006 and June 2014, 3308 patients were identified through the SA mCRC registry: 1464 (44%) in Cohort A and 1844 (56%) in Cohort B. 61 and 59% patients in Cohort A and B, respectively received systemic therapy (p = 0.26). Major differences in clinical characteristics were: biological therapy use 18 versus 33% (p rise in bevacizumab administration was observed in Cohort B. Its use in first-line therapy remained relatively low even after the reimbursement, potentially reflecting real world practice where comorbidities, primary in-situ and age may contraindicate its use. mOS improvement over time was attributed to increased access to biological therapy, especially bevacizumab and possibly advance in peri-operative and supportive care.

    Grid services are the fundamental building blocks of today's Distributed Computing Infrastructures (DCI). The discovery of services in the DCI is a primary function that is a precursor to other tasks such as workload and data management. In this context, a service registry can be used to fulfil such a requirement. Existing service registries, such as the ARC Information Index or UNICORE Registry, are examples that have proven themselves in production environments. Such implementations provide a centralized service registry, however, todays DCIs, such as EGI, are based on a federation model. It is therefore necessary for the service registry to mirror such a model in order for it to seamlessly fit into the operational and management requirements - a DCI built using federated approach. This document presents an architecture for a federated service registry and a prototype based on this architecture, the EMI Registry. Special attention is given to how the federated service registry is robust to environment failu...

    This study was performed in Radiation and Isotopes Center of Khartoum (RICK) and National Cancer Institute (NCI) University of Gazeria. It focused on cancer patients who were treated by radiation therapy in the period between 2008 and 2009. The study investigator the risk and causative factors and geographical distribution over the sudan states and the relationship of incidence with some patient's customs and dietary habits. This study summarizes recent scientific evidence of environmental and occupational links to nearly 30 types of cancer. the discussion of each cancer type is introduced by highlights of trends in incidence. The study considers additional indication that involuntary exposures are linked to cancers, such as patterns observed in different geographic areas and among different population patterns of cancer in children. The purpose of this study is to review scientific evidence, particular y epidemiologic evidence. regarding the contribution of environmental and occupational exposures to the overall cancer incidence in the Sudan. The study discussed that the widespread exposures from air and water pollution, the work environment, exposure resulting form personal habits such as smoking and drinking and the diet are major contributors to cancer in human. In the past three decades, there have been several efforts to estimate the proportion of caner due to these involuntary exposure, starting with an ambitious effort by different scientists. This study provided and alternative interpretation of the evidence of cancer incidence to particular factors. We conclude the study by recommending the significance of giving environmental and occupational links to cancer serious consideration by individuals and institutions concerned with cancer prevention, particularly those involved in research and education.

    Full Text Available Abstract Background Although few studies have linked cognitive variables with adherence to mammography screening in women with family histories of breast and/or ovarian cancer, research studies suggest cognitive phenomena can be powerful adherence predictors. Methods This prospective study included 858 women aged 30 to 71 years from the Ontario site of the Breast Cancer Family Registry with at least one first-degree relative diagnosed with breast and/or ovarian cancer. Data on beliefs about breast cancer screening and use of mammography were obtained from annual telephone interviews spanning three consecutive years. Self-reported mammogram dates were confirmed with medical imaging reports. Associations between beliefs about breast cancer screening and adherence with annual mammography were estimated using polytomous logistic regression models corrected for familial correlation. Models compared adherers (N = 329 with late-screeners (N = 382 and never-screeners (N = 147. Results Women who believed mammography screening should occur annually were more likely to adhere to annual screening recommendations than women who believed it should happen less often (OR: 5.02; 95% CI: 2.97-8.49 for adherers versus late-screeners; OR: 6.82; 95% CI: 3.29-14.16 for adherers versus never-screeners. Women who believed mammography screening should start at or before age 50 (rather than after (OR: 9.72; 95% CI: 3.26-29.02 were significantly more likely to adhere when compared with never-screeners. Conclusions Study results suggest that women with a family history of breast cancer should be strongly communicated recommendations about initial age of screening and screening intervals as related beliefs significantly predict adequate adherence.

  20. Neoadjuvant Radiation Is Associated With Improved Survival in Patients With Resectable Pancreatic Cancer: An Analysis of Data From the Surveillance, Epidemiology, and End Results (SEER) Registry

    International Nuclear Information System (INIS)

    Purpose: Cancer of the exocrine pancreas is the fifth leading cause of cancer death in the United States. Neoadjuvant chemoradiation has been investigated in several trials as a strategy for downstaging locally advanced disease to resectability. The aim of the present study is to examine the effect of neoadjuvant radiation therapy (RT) vs. other treatments on long-term survival for patients with resectable pancreatic cancer in a large population-based sample group. Methods and Materials: The Surveillance, Epidemiology, and End Results (SEER) registry database (1994-2003) was queried for cases of surgically resected pancreatic cancer. Retrospective analysis was performed. The endpoint of the study was overall survival. Results: Using Kaplan-Meier analysis we found that the median overall survival of patients receiving neoadjuvant RT was 23 months vs. 12 months with no RT and 17 months with adjuvant RT. Using Cox regression and controlling for independent covariates (age, sex, stage, grade, and year of diagnosis), we found that neoadjuvant RT results in significantly higher rates of survival than other treatments (hazard ratio [HR], 0.55; 95% confidence interval, 0.38-0.79; p = 0.001). Specifically comparing adjuvant with neoadjuvant RT, we found a significantly lower HR for death in patients receiving neoadjuvant RT rather than adjuvant RT (HR, 0.63; 95% confidence interval, 0.45-0.90; p = 0.03). Conclusions: This analysis of SEER data showed a survival benefit for the use of neoadjuvant RT over surgery alone or surgery with adjuvant RT in treating pancreatic cancer. Therapeutic strategies that use neoadjuvant RT should be further explored for patients with resectable pancreatic cancer

  3. Substantial contribution of extrinsic risk factors to cancer development | Office of Cancer Genomics

    Science.gov (United States)

    Recent research has highlighted a strong correlation between tissue-specific cancer risk and the lifetime number of tissue-specific stem-cell divisions. Whether such correlation implies a high unavoidable intrinsic cancer risk has become a key public health debate with the dissemination of the 'bad luck' hypothesis. Here we provide evidence that intrinsic risk factors contribute only modestly (less than ~10-30% of lifetime risk) to cancer development.

    Full Text Available Pancreatic adenocarcinoma (PDAC is one of the most lethal human malignancies, with median survival of less than one year and overall five-year survival of less than 5%. There is increasing evidence demonstrating that epithelial-mesenchymal transition (EMT contributes to pancreatic cancer metastasis and to treatment resistance. In this review, we will examine the data demonstrating the role and regulation of EMT in pancreatic cancer progression, focusing particularly on the transcription factors and microRNAs involved in EMT. We will examine how EMT is involved in the generation and maintenance of stem cells, and the role of EMT in modulating resistance of PDAC cells to drug therapies. We will also identify putative EMT-targeting agents that may help to reduce the morbidity and mortality associated with pancreatic cancer.

    The search for infectious agents playing a role in human carcinogenesis and their identification remain important issues. This could provide clues for a broader spectrum of cancers preventable by vaccination and accessible to specific therapeutic regimens. Yet, the various ways of interacting among different factors functioning synergistically and their different modes of affecting individual cells should bring to question the validity of the term "causation". It also should put a word of caution into all attempts to summarize criteria for "causality" of infectious agents in cancer development. At least in the opinion of these authors, we would be much better off avoiding these terms, replacing "causal factor" by "risk factor" and grading them according to their contribution to an individual's cancer risk.

  6. Contribution of environment and genetics to pancreatic cancer susceptibility.

    Full Text Available Several risk factors have been identified as potential contributors to pancreatic cancer development, including environmental and lifestyle factors, such as smoking, drinking and diet, and medical conditions such as diabetes and pancreatitis, all of which generate oxidative stress and DNA damage. Oxidative stress status can be modified by environmental factors and also by an individual's unique genetic makeup. Here we examined the contribution of environment and genetics to an individual's level of oxidative stress, DNA damage and susceptibility to pancreatic cancer in a pilot study using three groups of subjects: a newly diagnosed pancreatic cancer group, a healthy genetically-unrelated control group living with the case subject, and a healthy genetically-related control group which does not reside with the subject. Oxidative stress and DNA damage was evaluated by measuring total antioxidant capacity, direct and oxidative DNA damage by Comet assay, and malondialdehyde levels. Direct DNA damage was significantly elevated in pancreatic cancer patients (age and sex adjusted mean ± standard error: 1.00 ± 0.05 versus both healthy unrelated and related controls (0.70 ± 0.06, pA and ERCC4 R415Q polymorphisms. These results suggest that measurement of DNA damage, as well as select SNPs, may provide an important screening tool to identify individuals at risk for development of pancreatic cancer.

  7. Contribution of radon and radon daughters to respiratory cancer

    International Nuclear Information System (INIS)

    This article reviews studies on the contribution of radon and radon daughters to respiratory cancer and proposes recommendations for further research, particularly a national radon survey. The steady-state outdoor radon concentration averages 200 pCi/m3, and indoor levels are about 4 times higher. The primary source of radon in homes is the underlying soil; entry depends on multiple variables and reduced ventilation for energy conservation increases indoor radon levels. Occupational exposures are expressed in units of radon daughter potential energy concentration or working level (WL). Cumulative exposure is the product of the working level and the time exposed. The unit for cumulative exposure is the working level month (WLM). The occupational standard for radon exposure is 4 WLM/year, and 2 WLM/year has been suggested as a guideline for remedial action in homes. Epidemiologic studies show that miners with cumulative radon daughter exposures somewhat below 100 WLM have excess lung cancer mortality. Some 3% to 8% of miners studied have developed lung cancer attributable to radon daughters. All of the underground mining studies show an increased risk of lung cancer with radon daughter exposure. All cell types of lung cancer increased with radon exposure. If radon and smoking act in a multiplicative manner, then the risk for smokers could be 10 times that for nonsmokers. The potential risk of lung cancer appears to be between 1 and 2 per 10,000/WLM, which yields a significant number of lung cancers as some 220 million persons in the United States are exposed on average to 10 to 20 WLM/lifetime

    2014-01-01

    In the Virtual Observatory (VO), the Registry provides the mechanism with which users and applications discover and select resources -- typically, data and services -- that are relevant for a particular scientific problem. Even though the VO adopted technologies in particular from the bibliographic community where available, building the Registry system involved a major standardisation effort, involving about a dozen interdependent standard texts. This paper discusses the server-side aspects of the standards and their application, as regards the functional components (registries), the resource records in both format and content, the exchange of resource records between registries (harvesting), as well as the creation and management of the identifiers used in the system based on the notion of authorities. Registry record authors, registry operators or even advanced users thus receive a big picture serving as a guideline through the body of relevant standard texts. To complete this picture, we also mention comm...

    The treatment of chronic myeloid leukemia (CML) has seen several major advances over the past 30 years, notably with the introduction of interferon followed by Bcr-Abl tyrosine kinase inhibitors. We analyzed trends in the incidence of CML and patient survival in France. All cases recorded in five population-based registries between 1980 and 2009 were included. European (ESR) and world (WSR) standardized incidence rates as well as relative survival (RS) rates were estimated. We analyzed data for 781 patients (9863/3: 13.6%; 9875/3: 82.2%; 9876/3: 4.2%). ESR was 1.02 [95% confidence interval (CI) = 0.93-1.11] and WSR was 0.81 [95% CI = 0.72-0.90]. The five RS rates among patients with Philadelphia chromosome positive (Ph+) CML were 43.7% [30.9-61.9] when diagnosed in 1980-1986, 63.8% [56.9-71.5] in 1987-1999 and 88.7% [84.5-93.0] in 2000-2009. The 8-year RS rate of patients with Ph+ CML diagnosed in 2000-2009 was 83.3% [77.5-89.4]. Therapeutic innovations have thus led to a significant increase in long-term survival in the general CML patient-population. PMID:25535815

    In 1988, the New York State Health Commissioner was confronted with hospital-level data demonstrating very large, multiple-year, interhospital variations in short-term mortality and complications for cardiac surgery. The concern with the extent to which these differences were due to variations in patients' pre-surgical severity of illness versus hospitals' quality of care led to the development of clinical registries for cardiac surgery in 1989 and for percutaneous coronary interventions in 1992 in New York. In 1990, the Department of Health released hospitals' risk-adjusted cardiac surgery mortality rates for the first time, and shortly thereafter, similar data were released for hospitals and physicians for percutaneous coronary interventions, cardiac valve surgery, and pediatric cardiac surgery (only hospital data). This practice is still ongoing. The purpose of this communication is to relate the history of this initiative, including changes or purported changes that have occurred since the public release of cardiac data. These changes include decreases in risk-adjusted mortality, cessation of cardiac surgery in New York by low-volume and high-mortality surgeons, out-of-state referral or avoidance of cardiac surgery/angioplasty for high-risk patients, alteration of contracting choices by insurance companies, and modifications in market share of cardiac hospitals. Evidence related to these impacts is reviewed and critiqued. This communication also includes a summary of numerous studies that used New York's cardiac registries to examine a variety of policy issues regarding the choice and use of cardiac procedures, the comparative effectiveness of competing treatment options, and the examination of the relationship among processes, structures, and outcomes of cardiac care.

    Cachexia is a devastating process especially in pancreatic cancer patients and contributes to their poor survival. We attempted to clarify the pathological and molecular changes that occur in the liver during the development of cachexia. Using immunohistochemistry we investigated the infiltration of inflammatory mononuclear cells in liver biopsies of pancreatic cancer patients with or without cachexia, and the potential relevance of the cells for the nutritional and inflammatory status. Additionally, these findings were compared with the patients' clinical parameters. We found a significantly higher amount of CD68 immunoreactive macrophages in liver cross sections of patients with pancreatic cancer and cachexia. The number of CD68-positive macrophages was significantly inversely correlated with the nutritional status. Additionally, in these CD68-positive areas a significant increase in IL-6 and IL-1 immunoreactive cells was localized. Moreover, we found significantly increased areas of CD68-positive macrophages in liver biopsies of patients with a more dedifferentiated (aggressive) grading of the tumor. In conclusion, these results suggest that a crucial interaction between the tumor, PBMCs, and the liver may play a central role in the development and regulation of cachexia. Furthermore, pancreatic cancer may be able to alter systemic organ function even without obvious metastatic disease. PMID:19148509

    Muscle protein wasting in cancer cachexia is a critical problem. The underlying mechanisms are still unclear, although the ubiquitin-proteasome system has been involved in the degradation of bulk myofibrillar proteins. The present work has been aimed to investigate whether autophagic degradation also plays a role in the onset of muscle depletion in cancer-bearing animals and in glucocorticoid-induced atrophy and sarcopenia of aging. The results show that autophagy is induced in muscle in three different models of cancer cachexia and in glucocorticoid-treated mice. In contrast, autophagic degradation in the muscle of sarcopenic animals is impaired but can be reactivated by calorie restriction. These results further demonstrate that different mechanisms are involved in pathologic muscle wasting and that autophagy, either excessive or defective, contributes to the complicated network that leads to muscle atrophy. In this regard, particularly intriguing is the observation that in cancer hosts and tumor necrosis factor α-treated C2C12 myotubes, insulin can only partially blunt autophagy induction. This finding suggests that autophagy is triggered through mechanisms that cannot be circumvented by using classic upstream modulators, prompting us to identify more effective approaches to target this proteolytic system.

  15. Stereotactic body radiotherapy for centrally located early-stage non-small cell lung cancer or lung metastases from the RSSearch® patient registry

    International Nuclear Information System (INIS)

    The purpose of this study was to evaluate treatment patterns and outcomes of stereotactic body radiotherapy (SBRT) for centrally located primary non-small cell lung cancer (NSCLC) or lung metastases from the RSSearch® Patient Registry, an international, multi-center patient registry dedicated to radiosurgery and SBRT. Eligible patients included those with centrally located lung tumors clinically staged T1-T2 N0, M0, biopsy-confirmed NSCLC or lung metastases treated with SBRT between November 2004 and January 2014. Descriptive analysis was used to report patient demographics and treatment patterns. Overall survival (OS) and local control (LC) were determined using Kaplan-Meier method. Toxicity was reported using the Common Terminology Criteria for Adverse Events version 3.0. In total, 111 patients with 114 centrally located lung tumors (48 T1-T2,N0,M0 NSCLC and 66 lung metastases) were treated with SBRT at 19 academic and community-based radiotherapy centers in the US and Germany. Median follow-up was 17 months (range, 1–72). Median age was 74 years for primary NSCLC patients and 65 years for lung metastases patients (p < 0.001). SBRT dose varied from 16 – 60 Gy (median 48 Gy) delivered in 1–5 fractions (median 4 fractions). Median dose to centrally located primary NSCLC was 48 Gy compared to 37.5 Gy for lung metastases (p = 0.0001) and median BED10 was 105.6 Gy for primary NSCLC and 93.6 Gy for lung metastases (p = 0.0005). Two-year OS for T1N0M0 and T2N0M0 NSCLC was 79 and 32.1 %, respectively (p = 0.009) and 2-year OS for lung metastases was 49.6 %. Two-year LC was 76.4 and 69.8 % for primary NSCLC and lung metastases, respectively. Toxicity was low with no Grade 3 or higher acute or late toxicities. Overall, patients with centrally located primary NSCLC were older and received higher doses of SBRT than those with lung metastases. Despite these differences, LC and OS was favorable for patients with central lung tumors treated with SBRT. Reported toxicity

    Objective: To describe incidence patterns and trends in children (0-14 years) and adolescents (15-19 age-range) with solid tumours, except those of central nervous system (CNS), in Spain. Methods: Cases were drawn from eleven Spanish population-based cancer registries. Incidence was estimated for the period 1983-2007 and trends were evaluated using Joinpoint regression analysis. Results: The studied tumour groups accounted for 36% of total childhood cancers and 47.6% of those diagnosed in adolescence with annual rates per million of 53.5 and 89.3 respectively. In children 0 to 14 years of age, Neuroblastoma (NB) was the commonest (7.8%) followed by Soft-tissue sarcomas (STS) (6.3%), bone tumours (BT) (6.2%) and renal tumours (RT) (4.5%). NB was the most frequently diagnosed tumour before the 5th birthday, while STS and BT were the commonest at 5-9 years of age, and BT and Carcinoma and other epithelial tumours (COET) at 10-14. COET presented the highest incidence in adolescents, followed by germ-cell tumours (GCT), BT and STS. These four diagnostic groups accounted for 94% of total non-CNS solid tumours, in adolescents. Overall incidence rates increased significantly in children up to 1996 with an annual percentage change (APC) of 2.6% (95%CI: 1.7; 3.6). NB and COET showed significant time trend (APCs: 1.4% and 3.8% respectively) while other tumour groups such as RT, STS, BT or GCT had no significant changes over time. A significant increase was present in NB under the age of 5 and in BT and STS in children aged 10-14 years. In adolescents there were significant increases for all tumours combined (APC=2.7; 95%CI: 1.8-3.6) and for STS, GCT and COET (APCs: 3.2%, 4.4% and 3.5% respectively), while other tumour groups such as hepatic tumours, BT or thyroid carcinomas showed a decreasing trend or no increase. Conclusions: Overall, the incidence of the studied cancers in children increased along the period 1983-1996 with no posterior significant rise, while the incidence

The aim of this performance improvement timing study was to identify trauma registry job responsibilities and redesign the responsibilities to create increased abstraction time and maintain accuracy of data abstraction. The outcome is measured by case submission rates with existing staffing and interrater reliability outcomes. PMID:25397337

    There have been significant advances in the treatment of patients with lymphoma and myeloma. Although the improvements in survival outcome have been clearly addressed by clinical trials, these studies includes patients who are otherwise healthy and would be eligible for trials that the actual improvement in survival in the general patient population over time is yet to be elucidated. Therefore, we reviewed the cancer-registry data of patients with lymphoma and myeloma in Japan from 1993 to 2006 and estimated relative survival (adjusted for competing causes of death in same-age members of the general population) according to three periods of diagnosis (1993-1997, 1998-2002 and 2003-2006). We also estimated conditional 5-year relative survival (5-year survival rate of patients who have survived 5 years). A total of 26,141 patients were reviewed and analyzed. Relative survival improved in Hodgkin lymphoma (HL, N = 853, +20% improvement), diffuse large B-cell lymphoma (DLBCL, N = 4,919, +14% improvement) and follicular lymphoma (FL, N = 1,333, +13% improvement). In contrast, we found no significant improvement in survival since 1993 in peripheral T-cell lymphoma (PTCL, N = 667, +4% improvement), adult T-cell leukemia/lymphoma (ATLL, N = 2,166, -5% improvement) or multiple myeloma (MM, N = 4,914, -2% improvement). Conditional 5-year survival of HL, DLBCL, FL, PTCL, ATLL and MM was 88, 87, 79, 63, 53 and 45%, respectively. Relative survival of patients with HL, DLBCL and FL significantly improved from 1993 to 2006 in Japan; in contrast, no improvement was seen in other diseases, suggesting unmet need of novel treatment strategies.

    Objectives Immunohistochemistry for DNA mismatch repair proteins is used to screen for Lynch syndrome in individuals with colorectal carcinoma (CRC). Although solitary loss of PMS2 expression is indicative of carrying a germline mutation in PMS2, previous studies reported MLH1 mutation in some cases. We determined the prevalence of MLH1 germline mutations in a large cohort of individuals with a CRC demonstrating solitary loss of PMS2 expression. Design This cohort study included 88 individuals affected with a PMS2-deficient CRC from the Colon Cancer Family Registry Cohort. Germline PMS2 mutation analysis (long-range PCR and multiplex ligation-dependent probe amplification) was followed by MLH1 mutation testing (Sanger sequencing and multiplex ligation-dependent probe amplification). Results Of the 66 individuals with complete mutation screening, we identified a pathogenic PMS2 mutation in 49 (74%), a pathogenic MLH1 mutation in 8 (12%) and a MLH1 variant of uncertain clinical significance predicted to be damaging by in silico analysis in 3 (4%); 6 (9%) carried variants likely to have no clinical significance. Missense point mutations accounted for most alterations (83%; 9/11) in MLH1. The MLH1 c.113A> G p.Asn38Ser mutation was found in 2 related individuals. One individual who carried the MLH1 intronic mutation c.677+3A>G p.Gln197Argfs*8 leading to the skipping of exon 8, developed 2 tumours, both of which retained MLH1 expression. Conclusions A substantial proportion of CRCs with solitary loss of PMS2 expression are associated with a deleterious MLH1 germline mutation supporting the screening for MLH1 in individuals with tumours of this immunophenotype, when no PMS2 mutation has been identified.

    In Sicily, between 2002 and 2004, 1,950 new cases of TC were identified, with an age-standardized rate (world ASR(w=17.8/100000 in females and 3.7/100000 in males and a high female/male ratio (4.3:1.0. The incidence of TC was heterogeneous within Sicily. There were 2.3 times more cases in the Catania province (where most of the inhabitants live in the volcanic area of Mt. Etna: ASR(w=31.7/105 in females and 6.4/105 in males vs 14.1 in females and 3.0 in males in the rest of Sicily. Multivariate analysis documented that residents in the volcanic area of Mt. Etna had a higher risk of TC, compared to the residents in urban, industrial and iodine deficient areas of Sicily. An abnormally high concentration of several chemicals was found in the drinking water of the Mt. Etna aquifer, which provides water to most of the residents in the Catania province. Our data suggest that environmental carcinogen(s of volcanic origin may promote papillary TC. Additional analyses, including cancer biological and molecular features, will allow a better understanding of risk factors and etiopathogenetic mechanisms.

    International Nuclear Information System (INIS)

    In this work four original observations of more or less long-delayed cancers induced by ionizing radiations are compared with 34 other cases in the literature, after which an attempt is made to establish a general and prognostic synthesis of the results; the indications to emerge are as follows: - Ionizing radiation-induced cancers are very rare, especially when compared with the extensive therapeutic use made of X-rays; - The probability of radio-cancer formation, though no figures are given in the many papers consulted, seems nevertheless to be higher in cases of benign lesion irradiation; - Induced cancers have been observed after treatments with all types of radiation, whether or not the lesion is tumoral or cancerous, whatever the patient's age at the time of irradiations; - As a general rule these neoplasms appear after a variable latency period but usually from the 6th post-radiotherapy year onwards, with a greater frequency range between 6 and 12 years; - These induced cancers are generally epitheliomas or sarcomas, the latter being noticeably more predominant than in the case of spontaneous cancers. Leukoses may also be observed

    Introduction: The Danish Twin Registry is a unique source for studies of genetic, familial and environmental factors on life events, health conditions and diseases. Content: More than 85,000 twin pairs born 1870-2008 in Denmark. Validity and coverage: Four main ascertainment methods have been...... employed. Completeness of ascertainment varies according to birth cohorts. For birth cohorts 1870-1930 both twins should survive to age 6 years. From 1931-1968 72% of all twin pairs has been ascertained, with complete ascertainment of all live born twins since 1968. CONCLUSION: Because twins have been...... identified independent of traits and on a population basis, the Danish Twin Registry is well suited for studies to understand the influence of genetic and environmental factors for a wide variety of diseases and traits....

  13. Hypoxia Induced Tumor Metabolic Switch Contributes to Pancreatic Cancer Aggressiveness

    International Nuclear Information System (INIS)

    Pancreatic ductal adenocarcinoma remains one of the most lethal of all solid tumors with an overall five-year survival rate of only 3–5%. Its aggressive biology and resistance to conventional and targeted therapeutic agents lead to a typical clinical presentation of incurable disease once diagnosed. The disease is characterized by the presence of a dense stroma of fibroblasts and inflammatory cells, termed desmoplasia, which limits the oxygen diffusion in the organ, creating a strong hypoxic environment within the tumor. In this review, we argue that hypoxia is responsible for the highly aggressive and metastatic characteristics of this tumor and drives pancreatic cancer cells to oncogenic and metabolic changes facilitating their proliferation. However, the molecular changes leading to metabolic adaptations of pancreatic cancer cells remain unclear. Cachexia is a hallmark of this disease and illustrates that this cancer is a real metabolic disease. Hence, this tumor must harbor metabolic pathways which are probably tied in a complex inter-organ dialog during the development of this cancer. Such a hypothesis would better explain how under fuel source limitation, pancreatic cancer cells are maintained, show a growth advantage, and develop metastasis

    Background Many prostate cancers (pcas) are indolent and, if left untreated, are unlikely to cause death or morbidity in a man’s lifetime. As a result of testing for prostate-specific antigen, more such cases are being identified, leading to concerns about “overdiagnosis” and consequent overtreatment of pca. To mitigate the risks associated with overtreatment (that is, invasive therapies that might cause harm to the patient without tangible benefit), approaches such as active surveillance are now preferred for many men with low-risk localized pca (specifically, T1/2a, prostate-specific antigen ≤ 10 ng/mL, and Gleason score ≤ 6). Here, we report on patterns of care and treatment trends for men with localized low-risk pca. Results The provinces varied substantially with respect to the types of primary treatment received by men with localized low-risk pca. From 2010 to 2013, many men had no record of surgical or radiation treatment within 1 year of diagnosis—a proxy for active surveillance; the proportion ranged from 53.3% in Nova Scotia to 80.8% in New Brunswick. Among men who did receive primary treatment, the use of radical prostatectomy ranged from 12.0% in New Brunswick to 35.9% in Nova Scotia. The use of radiation therapy (external-beam radiation therapy or brachytherapy) ranged from 4.1% in Newfoundland and Labrador to 17.6% in Alberta. Treatment trends over time suggest an increase in the use of active surveillance. The proportion of men with low-risk pca and no record of surgical or radiation treatment rose to 69.9% in 2013 from 46.1% in 2010 for all provinces combined. Conclusions The provinces varied substantially with respect to patterns of care for localized low-risk pca. Treatment trends over time suggest an increasing use of active surveillance. Those findings can further the discussion about the complex care associated with pca and identify opportunities for improvement in clinical practice. PMID:26966405

Methods: The Saskatchewan Registry is a prospective, observational, multicenter cohort study that identifies consecutive patients started on ticagrelor. We aimed to evaluate both on- and off-label use, identify characteristics of patients who prematurely stop ticagrelor, and describe patient/physician behavior contributing to inappropriate stoppage of this medication. Results: From April 2012 to September 2013, 227 patients were initiated on ticagrelor, with a mean age of 62.2±12.1 years. The participants were 66% men and had a mean follow up of 157.4±111.7 days. Seventy-four patients (32.4% had off-label indications. Forty-seven patients (20.7% prematurely stopped ticagrelor and were more likely to be older, women, nonwhite, present with shock, and complain of dyspnea. Twenty-six of the 47 patients stopped ticagrelor inappropriately because of patient nonadherence (18 patients and physician advice (eight patients. A composite outcome event of death from vascular causes, myocardial infarction, or stroke occurred in 8.8% of the entire cohort and was more likely to occur in those older then 65 years, those presenting with cardiogenic shock, and those who prematurely stopped ticagrelor. Conclusion: In this real-world registry of patients started on ticagrelor, a third have off-label indications and a fifth prematurely stop the medication. Premature discontinuation was an independent predictor of major

  17. Pelvic lymphoscintigraphy: contribution to the preoperative staging of rectal cancer

    International Nuclear Information System (INIS)

    Preservation of the lower rectal sphincters has been the main concern of colorectal surgeons in an attempt to avoid colostomy. Various proposed procedures contradict the oncological principles of the operation's radicality, especially pelvic lymphadenectomy. Prior knowledge of this space is therefore, an important factor in choosing the operative technique: radical (amputation), or conservative. The introduction of ultrasound, computed tomography and magnetic resonance imaging, have provided preoperative information about the anatomic nature of the region. The morphological and functional study supplied by lymphoscintigraphy of this space supplements the data furnished by the other imaging techniques. The objective of this prospective of this prospective study was threefold: to standardize lymphoscintigraphy, to differentiate patients with rectal cancer from those with other coloproctological diseases and to asses the lymphonodal involvement in the former by utilizing the anatomopathological and surgical correlation. The study included 60 patients with various coloproctological diseases seen on the Department of Gastroentorology, Hospital da Clinicas, University of Sao Paulo School of Medicine, from September 1990 to August 1993. Thirty were cases of rectal cancer and the remainder were other colorectal diseases. The method consisted of injecting 0.5 of a dextran solution market with radioactive technetium in the perineal region and obtaining images by a gamma camera. In the rectal cancer patients, the tracer progresses unilaterally or is absent; in the others, it is bilateral and symmetrical, although its progress may be slow. The statistical data demonstrated that in rectal cancer, lymphoscintigraphy asseses the nodal involvement approximaltely as that obtained by the sun of the anatomapathological and surgical findings. Based on the results, the following conclusioons were possible: lymphoscintigraphy is a standardized, painless and harmless test that can be

    Cells assemble mitotic spindles during each round of division to insure accurate segregation of their duplicated genome. In animal cells, stereotypical spindles have two poles, each containing one centrosome, from which microtubules are nucleated. By contrast, many cancer cells often contain more than two centrosomes and form transient multipolar spindle structures with more than two poles. In order to divide and produce viable progeny, the multipolar spindle intermediate must be reshaped into a pseudo-bipolar structure via a process called centrosomal clustering. Pseudo-bipolar spindles appear to function normally during mitosis, but they occasionally give rise to aneuploid and transformed daughter cells. Agents that inhibit centrosomal clustering might therefore work as a potential cancer therapy, specifically targeting mitosis in supernumerary centrosome-containing cells. PMID:27046071

    To increase dietary intake and to fight anorexia several measures to treat symptoms and administer the most adequate diet according to composition, texture and flavour are proposed. However, in the anorexia-caquexia present in cancer patients not always these measures are effective. Now a day it seems more reasonable to approach this problem with different strategies directed to modulate the pathologic alterations associated. The analysis of specific nutritional support as part as the treatment of these patients from a systematic review conclude that no high methodological quality studies to analyze the impact of oral supplementation on a specific group of patients, neither the study of functional effects are done. However, an increase in the total energy intake, not maintained over the time, was observed. The effects on weight and corporal composition are variable, with small differences between groups with o without supplementation and confuse due to, mainly, the heterogeneity of the patients included in the different studies analyzed. The analysis of the effects of nutritional supplements administered by enteral feeding shown an increase in the energy intake with an increase in body weight or a lack of decrease it, and with some functional and clinical beneficial effects. Despite the results and conclusions obtained, a strong recommendation to conduct clinical trials in specific group of cancer patients with different antineoplasic treatment seems necessary. N-3 fatty acids, especially eicosapentaenoic acid may have anticachectic properties. Although further trials are necessary the limited results available suggests that nutritional supplements enriched with EPA may reverse cachexia in cancer patients. PMID:16768028

    Objectives Anemia is a common complication of malignancy, which could result from either compromised erythropoiesis or decreased lifespan of circulating erythrocytes. Premature suicidal erythrocyte death, characterized by cell shrinkage and phosphatidylserine (PS) externalization, decreases erythrocyte lifespan and could thus cause anemia. Here, we explored whether accelerated eryptosis participates in the pathophysiology of anemia associated with lung cancer (LC) and its treatment. Methods Erythrocytes were drawn from healthy volunteers and LC patients with and without cytostatic treatment. PS exposure (annexin V-binding), cell volume (forward scatter), cytosolic Ca2+ (Fluo3 fluorescence), reactive oxygen species (ROS) production (DCFDA fluorescence) and ceramide formation (anti-ceramide antibody) were determined by flow cytometry. Results Hemoglobin concentration and hematocrit were significantly lower in LC patients as compared to healthy controls, even though reticulocyte number was higher in LC (3.0±0.6%) than in controls (1.4±0.2%). The percentage of PS-exposing erythrocytes was significantly higher in LC patients with (1.4±0.1%) and without (1.2±0.3%) cytostatic treatment as compared to healthy controls (0.6±0.1%). Erythrocyte ROS production and ceramide abundance, but not Fluo3 fluorescence, were significantly higher in freshly drawn erythrocytes from LC patients than in freshly drawn erythrocytes from healthy controls. PS exposure of erythrocytes drawn from healthy volunteers was significantly more pronounced following incubation in plasma from LC patients than following incubation in plasma from healthy controls. Conclusion Anemia in LC patients with and without cytostatic treatment is paralleled by increased eryptosis, which is triggered, at least in part, by increased oxidative stress and ceramide formation.

  8. Utility of an Australasian registry for children undergoing radiation treatment

    International Nuclear Information System (INIS)

    The aim of this study was to evaluate the utility of an Australasian registry ('the Registry') for children undergoing radiation treatment (RT). Children under the age of 16years who received a course of radiation between January 1997 and December 2010 and were enrolled on the Registry form the subjects of this study. A total of 2232 courses of RT were delivered, predominantly with radical intent (87%). Registrations fluctuated over time, but around one-half of children diagnosed with cancer undergo a course of RT. The most prevalent age range at time of RT was 10–15years, and the most common diagnoses were central nervous system tumours (34%) and acute lymphoblastic leukaemia (20%). The Registry provides a reflection of the patterns of care of children undergoing RT in Australia and a mechanism for determining the resources necessary to manage children by RT (human, facilities and emerging technologies, such as proton therapy). It lacks the detail to provide information on radiotherapy quality and disease outcomes which should be the subject of separate audit studies. The utility of the Registry has been hampered by its voluntary nature and varying needs for consent. Completion of registry forms is a logical requirement for inclusion in the definition of a subspecialist in paediatric radiation oncology.

We show that murine and humantumor cells cocultivated with mature adipocytes exhibit increased invasive capacities in vitro and in vivo, usingan original two-dimensional coculture system. Likewise, adipocytes cultivated with cancer cells also exhibit analtered phenotype in terms of delipidation and decreased ...

    Full Text Available BACKGROUND: Sex differences have been reported in the prognosis of certain cancers. In this study, we investigated whether Korean females display better survival rates compared with male patients for solid tumor sites. METHODS: We analyzed data from the Korean National Cancer Incidence Database from 599,288 adult patients diagnosed with solid cancers between 2005 and 2009. Patients were followed until December 2010. We applied a relative excess risk (RER model adjusting for year of follow-up, age at diagnosis, and stage at diagnosis. RESULTS: For all solid cancer sites combined, women displayed an 11% lower risk of death compared to men (RER 0.89; 95% CI 0.88-0.90 after adjusting for year of follow-up, age, stage, and case mix. Women showed significantly lower RERs for the following sites: head/neck, esophagus, small intestine, liver, nasal cavities, lung, bone/cartilages, melanoma of skin, soft tissue, brain and CNS, and thyroid. In contrast, women displayed a poorer prognosis than did men for colorectal, laryngeal, kidney and bladder cancer. However, the survival gaps between men and women narrowed by increase in age; female patients over 75 years of age displayed a 3% higher RER of death compared with males in this age group. CONCLUSIONS: Female cancer patients display an improved survival for the majority of solid tumor sites, even after adjustment for age and stage. Age at diagnosis was the major contributor to the women's survival advantage.

  16. Contribution of Radon Exposure to the Risk of Lung Cancer Assessed by Applying a Multifactor Analysis

    International Nuclear Information System (INIS)

    Full text: It is well known that many different carcinogenic risk factors contribute to the development of lung cancer. Smoking, occupational exposure to carcinogens, chronic lung diseases and industrial air pollution are the most significant of them. Indoor radon exposure is considered a weak carcinogenic risk factor in the Urals, Russia. A drawback of traditionally applied monofactor methods of epidemiologic analysis is that different carcinogenic risk factors are analysed separately and their complex effect on public health is not taken into account. With such an approach it is impossible to adequately assess each factor's contribution in the total carcinogenic risk. For this reason it is expedient to apply methods of multifactor analysis in epidemiologic studies. We applied mathematical methods of pattern recognition when analysing the effect of indoor radon exposure on the development of lung cancer in the population of two Ural cities. We assessed the association between radon/thoron exposures and lung cancer using both BEIR VI model and the above-mentioned methods. The results were significantly different. According to BEIR VI model the contribution of radon/thoron in the risk of lung cancer varied from 7.2% to 33%, whereas this contribution assessed in the multifactor analysis was only 0.5%. We think that the contribution assessed in BEIR VI model is overestimated. Our considerable experience in conducting epidemiologic studies using mathematical methods of pattern recognition, gives us grounds to state that the assessment of radon/thoron exposure on lung cancer risk obtained in the multifactor analysis is more adequate and precise.

  17. The SystHERs registry: an observational cohort study of treatment patterns and outcomes in patients with human epidermal growth factor receptor 2–positive metastatic breast cancer

    International Nuclear Information System (INIS)

    Amplification of the human epidermal growth factor receptor 2 (HER2) gene occurs in approximately 20% of invasive breast cancer cases and is associated with a more aggressive disease course than HER2-negative breast cancer. HER2-targeted therapies have altered the natural history of HER2-positive breast cancer, a trend that will likely further improve with the recent approval of new agents. A prospective, observational cohort study was designed and initiated to provide real-world insights into current treatment patterns, long-term survival, and patients’ experiences with initial and subsequent treatments for HER2-positive metastatic breast cancer (MBC). The Systematic Therapies for HER2-positive Metastatic Breast Cancer Study (SystHERs) is a US-based prospective observational cohort study enrolling patients ≥18 years of age with recently diagnosed HER2-positive MBC not previously treated with systemic therapy in the metastatic setting. The primary objective of the study is to identify treatment patterns and clinical outcomes in recently diagnosed patients in a variety of practice settings. Secondary objectives include comparative efficacy, safety, and patient-reported outcomes (PROs). Healthcare resource utilization is an exploratory end point. Tumor tissue and blood sample collection is optional. The SystHERs registry will enroll approximately 1000 patients over a 3-year period, after which the study will continue for ≥5 years, allowing for a maximum follow-up of 8 years. The treating physician will determine all care and the frequency of visits. PRO measures will be completed at study enrollment and every 90 days. Clinical data will be abstracted quarterly from patient records. The first patient was enrolled in June 2012, and preliminary descriptive data based on 25% to 30% of the final study population are expected at the end of 2013, and as of April 25, 2014, 386 patients are enrolled. SystHERs is expected to provide in-depth data on demographic

    The variability in deceased organ donation registries worldwide has received little attention. We considered all operating registries, where individual wishes about organ donation were recorded in a computerized database. We included registries which recorded an individual's decision to be a donor (donor registry), and registries which only recorded an individual's objection (non-donor registry). We collected information on 15 characteristics including history, design, use and number of registrants for 27 registries (68%). Most registries are nationally operated and government-owned. Registrations in five nations expire and require renewal. Some registries provide the option to make specific organ selections in the donation decision. Just over half of donor registries provide legally binding authorization to donation. In all national donor registries, except one, the proportion of adults (15+) registered is modest (donation decision mandatory to obtain a driver's license. Registered objections in non-donor registries are rare (organ donor registries worldwide necessitates public discourse and quality improvement initiatives, to identify and support leading practices in registry use.

  2. Reprint of: cancer "causation" by infections--individual contributions and synergistic networks.

    Science.gov (United States)

    Zur Hausen, Harald; de Villiers, Ethel-Michele

    2015-04-01

    The search for infectious agents playing a role in human carcinogenesis and their identification remain important issues. This could provide clues for a broader spectrum of cancers preventable by vaccination and accessible to specific therapeutic regimens. Yet, the various ways of interacting among different factors functioning synergistically and their different modes of affecting individual cells should bring to question the validity of the term "causation". It also should put a word of caution into all attempts to summarize criteria for "causality" of infectious agents in cancer development. At least in the opinion of these authors, we would be much better off avoiding these terms, replacing "causal factor" by "risk factor" and grading them according to their contribution to an individual's cancer risk.

  3. Increased incidence of myelodysplastic syndrome and acute myeloid leukemia following breast cancer treatment with radiation alone or combined with chemotherapy: a registry cohort analysis 1990-2005

    International Nuclear Information System (INIS)

    Our objective was to measure myelodysplastic syndrome (MDS) and acute myelogenous leukemia (AML) risk associated with radiation and/or chemotherapy breast cancer (BC) treatment. Our study cohort was composed of BC patients diagnosed from 1990 to 2005 and followed up for blood disorders, mean length of follow up = 7.17 years, range 2-18 years. 5790 TNM stage 0-III patients treated with surgery alone, radiation and/or chemotherapy were included. Patients without surgery (n = 111), with stem cell transplantation (n = 98), unknown or non-standard chemotherapy regimens (n = 94), lost to follow up (n = 66) or 'cancer status unknown' (n = 67) were excluded. Rates observed at our community based cancer care institution were compared to SEER incidence data for rate ratio (RR) calculations. 17 cases of MDS/AML (10 MDS/7 AML) occurred during the follow up period, crude rate .29% (95% CI = .17, .47), SEER comparison RR = 3.94 (95% CI = 2.34, 6.15). The RR of MDS in patients age < 65 comparing our cohort incidence to SEER incidence data was 10.88 (95% CI = 3.84, 24.03) and the RR of AML in patients age < 65 was 5.32 (95% CI = 1.31, 14.04). No significant increased risk of MDS or AML was observed in women ≥ 65 or the surgery/chemotherapy-only group. A RR of 3.32 (95% CI = 1.42, 6.45) was observed in the surgery/radiation-only group and a RR of 6.32 (95% CI = 3.03, 11.45) in the surgery/radiation/chemotherapy group. 3 out of 10 MDS cases died of disease at an average 3.8 months post diagnosis and five of seven AML cases died at an average 9 months post diagnosis. An elevated rate of MDS and AML was observed among breast cancer patients < 65, those treated with radiation and those treated with radiation and chemotherapy compared to available population incidence data. Although a small number of patients are affected, leukemia risk associated with treatment and younger age is significant

    Breast cancer incidence in Nigerian women has significantly increased during the past three decades in parallel with the rapid industrialization of that country. This suggested that the associated widespread contamination of the soil and of the water supplies by lead (Pb) and other industrial metals was a major contributing cause. Because of its many domestic, industrial, and automotive uses, Pb is of particular concern as it has been shown to promote the development of mammary tumors in muri...

    Introduction: Recent studies have revealed that cancer stem cells (CSCs) exist in malignant disease. Additionally, it is proposed that these cells may survive following chemotherapy, and hence contribute to tumour relapse. A significant mechanism of drug resistance in CSCs is believed to be the expression of ATP-binding cassette (ABC) transporters that efflux cytotoxic agents out of cells. The objective of this study was to study the existence of CSCs in a panel of primary paediatric brain tu...

    Full Text Available I would like to thank the Preservation Division for the invitation to participate in the programme today. I would also like to thank the LIBER Board for their interest in the early stages of this project culminating in the announcement LIBER President Erland Kolding Nielsen made last night about LIBER support and collaboration with OCLC PICA with respect to the Digital Registry. This initiative reflects my new role within OCLC PICA, which is to identify opportunities for joint development with our major shareholder OCLC, and sometimes 3rd parties such as LIBER. My main purpose today is to provide a descriptive paper to inform LIBER members about the OCLC Digital Registry and to outline the possible role for LIBER and its membership in a model for European participation. My presentation will be in three phases: the need for a registry, a description of the Registry and finally, and perhaps most importantly, to outline opportunities for LIBER and its members in establishing a model for European contribution. We are all familiar with the concept of a registry through our participation in union catalogues and perhaps also from our experience with microfilms through the European Register of Microform Masters (EROMM hosted by our friends in Göttingen.

    RNA-binding proteins (RBPs) bind to and post-transcriptionally regulate the stability of mRNAs. La-related protein 1 (LARP1) is a conserved RBP that interacts with poly-A-binding protein and is known to regulate 5'-terminal oligopyrimidine tract (TOP) mRNA translation. Here, we show that LARP1 is complexed to 3000 mRNAs enriched for cancer pathways. A prominent member of the LARP1 interactome is mTOR whose mRNA transcript is stabilized by LARP1. At a functional level, we show that LARP1 promotes cell migration, invasion, anchorage-independent growth and in vivo tumorigenesis. Furthermore, we show that LARP1 expression is elevated in epithelial cancers such as cervical and non-small cell lung cancers, where its expression correlates with disease progression and adverse prognosis, respectively. We therefore conclude that, through the post-transcriptional regulation of genes such as mTOR within cancer pathways, LARP1 contributes to cancer progression. PMID:25531318

    Lysine-specific demethylase 1 (LSD1) has been implicated in the process of tumor progression at various steps, but its role in epithelial-messenchymal transition (EMT) and the migration of ovarian cancer cells remains obscure. In this study, we demonstrated the effect of LSD1 on ovarian cancer cell migration and the regulatory role of LSD1 in the expression of EMT markers. Inhibition of LSD1 expression impaired the migration and invasion of HO8910 ovarian cancer cells. In contrast, overexpression of LSD1 enhanced the cell migration and invasion of HO8910 cells. Mechanistic analyses showed that LSD1 promoted cell migration through induction of N-cadherin, vimentin, MMP-2 and inhibition of E-cadherin. Furthermore, LSD1 interacted with the promoter of E-cadherin and demethylated histone H3 lysine 4 (H3K4) at this region, downregulated E-cadherin expression, and consequently enhanced ovarian cancer cell migration. These data indicate that LSD1 acts as an epigenetic regulator of EMT and contributes to the metastasis of ovarian cancer. PMID:27109588

  13. Contribution of whole body FDG-PET to the detection of distant metastasis in pancreatic cancer

    International Nuclear Information System (INIS)

    Accurate baseline staging is necessary to appropriately treat pancreatic cancer. The present study was undertaken to evaluate the clinical contribution of whole body fluorodeoxyglucose (FDG)-PET to the detection of distant metastasis in pancreatic cancer. A total of consecutive 42 patients with previously untreated pancreatic cancer were examined. Whole body FDG-PET imaging for initial staging was performed with a 3D acquisition and iterative reconstruction on Siemens ECAT HR+ scanner at 1 hour post 185-200 MBq 18F-FDG injection. PET findings were correlated with clinical and radiological data to determine the impact of PET on staging. In 16 patients, there were one or more sites of metastasis based on clinical data. FDG-PET correctly identified the presence of metastasis in 13 of 16 patients and its absence in 23 of the remaining 26 patients. Thus, FDG-PET missed 4 metastatic sites in 4 patients (liver and lung metastasis). FDG-PET correctly identified 8 metastatic sites in 7 patients (peritoneal dissemination and liver, bone and supraclavicular lymph node metastasis), which were missed on CT imaging. Based on whole body FDG-PET, the clinical stage was changed in 5 of 42 patients (11.9%). These results suggest that FDG-PET and CT appear to have a complementary role in the detection of distant metastasis in patients with pancreatic cancer. (author)

    2010-01-01

    Registries play a key role in service-oriented applications. Originally, they were neutral players between service providers and clients. The UDDI Business Registry (UBR) was meant to foster these concepts and provide a common reference for companies interested in Web services. The more Web services were used, the more companies started create their own local registries: more efficient discovery processes, better control over the quality of published information, and also more sophisticated publication policies motivated the creation of private repositories. The number and heterogeneity of the different registries - besides the decision to close the UBR are pushing for new and sophisticated means to make different registries cooperate. This paper proposes DIRE (DIstributed REgistry), a novel approach based on a publish and subscribe (P/S) infrastructure to federate different heterogeneous registries and make them exchange information about published services. The paper discusses the main motivations for the P...

  15. Ovarian cancer: contribution of radiation therapy to patient management: Erskine Memorial Lecture, 1983

    International Nuclear Information System (INIS)

    Ovarian cancer may be treated with radiation therapy, surgery, chemotherapy, or a combination. To evaluate the contribution of radiation therapy to patient management the cure rate must be estimated; data are presented suggesting that the 5-year survival rate provides a reasonable estimate of the cure rate. A study of patients treated since 1971 showed that stage and postoperative residuum could be used to divide patients into two subgroups, a poor prognosis group and a good prognosis group; a multifactorial grouping of patients in the good prognosis group who were treated postoperatively with radiation therapy only was further able to divide patients into low-risk, intermediate-risk, and high-risk groups. Studies of radiation therapy for different subgroups are discussed; abdominopelvic irradiation has been shown to improve survival for approximately one-third of patients with cancer of the ovary

    Full Text Available BACKGROUND: O(6-methylguanine-DNA methyltransferase is one of the few proteins to directly remove alkylating agents in the human DNA direct reversal repair pathway. A large number of case-control studies have been conducted to explore the association between MGMT Leu84Phe polymorphism and cancer risk. However, the results were not consistent. METHODS: We carried out a meta-analysis of 44 case-control studies to clarify the association between the Leu84Phe polymorphism and cancer risk. RESULTS: Overall, significant association of the T allele with cancer susceptibility was verified with meta-analysis under a recessive genetic model (P<0.001, OR=1.30, 95%CI 1.24-1.50 and TT versus CC comparison (P=0.001, OR=1.29, 95% CI 1.12-1.50. In subgroup analysis, a significant increased risk was found for lung cancer (TT versus CC, P=0.027, OR=1.67, 95% CI 1.06-2.63; recessive genetic model, P=0.32, OR=1.64, 95% CI 1.04-2.58, whereas risk of colorectal cancer was significantly low under a dominant genetic model (P=0.019, OR=0.84, 95% CI 0.72-0.97. Additionally, a significant association between TT genetic model and total cancer risk was found in the Caucasian population (TT versus CC, P=0.014, OR=1.29, 95% CI 1.05-1.59; recessive genetic model, P=0.009, OR=1.31, 95% CI 1.07-1.61, but not in the Asian population. An increased risk for lung cancer was also verified in the Caucasian population (TT versus CC, P=0.035, OR=1.62, 95% CI 1.04-2.53; recessive genetic model, P=0.048, OR=1.57, 95% CI 1.01-2.45. CONCLUSIONS: These results suggest that MGMT Leu84Phe polymorphism might contribute to the susceptibility of certain cancers.

    International Nuclear Information System (INIS)

    Purpose: Vascular closure devices are routinely used after many vascular interventional radiology procedures. However, there have been no major multicenter studies to assess the safety and effectiveness of the routine use of closure devices in interventional radiology. Methods: The CIRSE registry of closure devices with an anchor and a plug started in January 2009 and ended in August 2009. A total of 1,107 patients were included in the registry. Results: Deployment success was 97.2%. Deployment failure specified to access type was 8.8% [95% confidence interval (95% CI) 5.0–14.5] for antegrade access and 1.8% (95% CI 1.1–2.9) for retrograde access (P = 0.001). There was no difference in deployment failure related to local PVD at the access site. Calcification was a reason for deployment failure in only 5.9 cm, and two vessel occlusions. Conclusion: The conclusion of this registry of closure devices with an anchor and a plug is that the use of this device in interventional radiology procedures is safe, with a low incidence of serious access site complications. There seems to be no difference in complications between antegrade and retrograde access and other parameters.

    Purpose. This study was designed to elucidate the role of amplification at 8q24 in the pathophysiology of ovarian and breast cancer since increased copy number at this locus is one of the most frequent genomic abnormalities in these cancers. Experimental Design. To accomplish this, we assessed the association of amplification at 8q24 with outcome in ovarian cancers using FISH to tissue microarrays and measured responses of ovarian and breast cancer cell lines to specific small interfering RNAs (siRNA) against the oncogene, MYC, and a putative noncoding RNA, PVT1, both of which map to 8q24. Results. Amplification of 8q24 was associated with significantly reduced survival duration. In addition, siRNA-mediated reduction in either PVT1 or MYC expression inhibited proliferation in breast and ovarian cancer cell lines in which they were both amplified and over expressed but not in lines in which they were not amplified/over expressed. Inhibition of PVT1 expression also induced a strong apoptotic response in cell lines in which it was over expressed but not in lines in which it was not amplified/over expressed. Inhibition of MYC, on the other hand, did not induce an apoptotic response in cell lines in which MYC was amplified and over expressed. Conclusions. These results suggest that MYC and PVT1 contribute independently to ovarian and breast pathogenesis when over expressed because of genomic abnormalities. They also suggest that PVT1 mediated inhibition of apoptosis may explain why amplification of 8q24 is associated with reduced survival duration in patients treated with agents that act through apoptotic mechanisms.

    Ovarian cancer is the third most common gynaecological malignancy. Changes in circadian rhythms such as bright light exposure may affect female reproductive physiology. Night shift work is associated with higher risks of developing gynaecological cancers. In addition, the season of birth is also suggested as an important environmental risk factor for developing gynaecological cancers. Melatonin may play an important role in this association as a marker of circadian rhythms. Serum from 96 women with ovarian cancer and 40 healthy women were collected and the level of melatonin was measured. In addition 277 women with ovarian cancer and 1076 controls were retrospectively collected for season of birth analysis over seven years. The serum levels of melatonin were significantly lower in women with ovarian cancer compared with healthy women (p<0.05). However there was no difference in melatonin levels in perimenopausal and postmenopausal patients. In addition, there is no statistically significant difference in seasonal distribution of birth between ovarian cancer patients and the control group. The melatonin levels in ovarian cancer patients and controls were not associated with the season of birth. Our results demonstrate the lower serum levels of melatonin in ovarian cancer patients which may contribute to the pathogenesis of ovarian cancer. The incidence of ovarian cancer was not associated with the season of birth. The serum levels of melatonin do not appear to be associated with season of birth in ovarian cancer patients.

    The Twin Research Registry (TRR) at SRI International is a community-based registry of twins established in 1995 by advertising in local media, mainly on radio stations and in newspapers. As of August 2012, there are 3,120 same- and opposite-sex twins enrolled; 86% are 18 years of age or older (mean age 44.9 years, SD 16.9 years) and 14% less than 18 years of age (mean age 8.9 years, SD 4.5); 67% are female, and 62% are self-reported monozygotic (MZ). More than 1,375 twins have participated in studies over the last 15 years in collaboration with the University of California Medical Center in San Francisco, the University of Texas MD Anderson Cancer Center, and the Stanford University School of Medicine. Each twin completes a registration form with basic demographic information either online at the TRR Web site or during a telephone interview. Contact is maintained with members by means of annual newsletters and birthday cards. The managers of the TRR protect the confidentiality of twin data with established policies; no information is given to other researchers without prior permission from the twins; and all methods and procedures are reviewed by an Institutional Review Board. Phenotypes studied thus far include those related to nicotine metabolism, mutagen sensitivity, pain response before and after administration of an opioid, and a variety of immunological responses to environmental exposures, including second-hand smoke and vaccination for seasonal influenza virus and Varicella zoster virus. Twins in the TRR have participated in studies of complex, clinically relevant phenotypes that would not be feasible to measure in larger samples. PMID:23084148

    if, mortality, incidence and patients’ survival data are high quality and complete. The MIAMOD method was developed to provide incidence, prevalence and mortality estimates and projections, using mortality and patients’ survival information at national or regional levels. Examples of application of the MIAMOD method to national cancer registries in Europe are given to show the performance of the method in checking the CR data for internal consistency and completeness of registration. We are proposing the MIAMOD method and software as a tool for CR useful to check for completeness and quality of their data and to provide future cancer burden information for health planning and allocation of resources for their area

    Full Text Available BACKGROUND: Bone cancer pain seriously affects the quality of life of cancer patients. Our previous study found that endogenous formaldehyde was produced by cancer cells metastasized into bone marrows and played an important role in bone cancer pain. However, the mechanism of production of this endogenous formaldehyde by metastatic cancer cells was unknown in bone cancer pain rats. Lysine-specific demethylase 1 (LSD1 is one of the major enzymes catalyzing the production of formaldehyde. The expression of LSD1 and the concentration of formaldehyde were up-regulated in many high-risk tumors. OBJECTIVE: This study aimed to investigate whether LSD1 in metastasized MRMT-1 breast cancer cells in bone marrows participated in the production of endogenous formaldehyde in bone cancer pain rats. METHODOLOGY/PRINCIPAL FINDINGS: Concentration of the endogenous formaldehyde was measured by high performance liquid chromatography (HPLC. Endogenous formaldehyde dramatically increased in cultured MRMT-1 breast cancer cells in vitro, in bone marrows and sera of bone cancer pain rats, in tumor tissues and sera of MRMT-1 subcutaneous vaccination model rats in vivo. Formaldehyde at a concentration as low as the above measured (3 mM induced pain behaviors in normal rats. The expression of LSD1 which mainly located in nuclei of cancer cells significantly increased in bone marrows of bone cancer pain rats from 14 d to 21 d after inoculation. Furthermore, inhibition of LSD1 decreased the production of formaldehyde in MRMT-1 cells in vitro. Intraperitoneal injection of LSD1 inhibitor pargyline from 3 d to 14 d after inoculation of MRMT-1 cancer cells reduced bone cancer pain behaviors. CONCLUSION: Our data in the present study, combing our previous report, suggested that in the endogenous formaldehyde-induced pain in bone cancer pain rats, LSD1 in metastasized cancer cells contributed to the production of the endogenous formaldehyde.

  5. The United States Transuranium and Uranium Registries: 1968-1993

    International Nuclear Information System (INIS)

    The historical development and scientific contributions of the United States Transuranium and Uranium Registries are briefly traced. Further to encourage radiobiology studies and to provide unique materials for research in other areas such as biomarkers including oncogenes, the Registries have established the National Human Radiobiology Tissue Repository, which includes more than 20,000 tissue samples and solutions, histopathology slides, and related materials from persons with internal depositions, including radium dial painters, available to other investigators for collaborative or individual research purposes. Emphasis is given to recent findings of the Registries with respect to biokinetic models for the actinides and the post-mortem analysis of USTUR Case 0246, an individual who suffered a massive intake of 241Am eleven years prior to death from heart disease. Registries studies show that, in addition to skeleton and liver, muscle is an appreciable reservoir for both plutonium and americium. The systemic biokinetics of plutonium and americium are well represented by a three-compartment model that includes skeleton, liver, and muscle, although the biokinetic parameters of these two transuranium elements differ significantly. Initial uptake fractions for plutonium are 0.4, 0.4, and 0.2, with residence half-times of 50, 20 and 10 years, respectively, for skeleton, liver and muscle. For americium, the comparable uptake fractions are 0.45, 0.25, 0.3 with residence half-times of 50, 2.5 and 10 years for the three compartments. (author)

    Petabytes of Earth science data have been accumulated through space- and air-borne Earth observation programs during the last several decades. The data are valuable both scientifically and socioeconomically. The value of these data could be further increased significantly if the data from these programs can be easily discovered, accessed, integrated, and analyzed. The Global Earth Observation System of Systems (GEOSS) is addressing this need. Coordinated by the Group on Earth Observations (or GEO), a voluntary partnership of 86 governments, the European Commission, and 61 intergovernmental, international, and regional organizations has been working on implementing GEOSS for a number of years. After four years of international collaboration, the GEOSS Common Infrastructure (GCI) has been established. GCI consists of the Standards and Interoperability Registry (SIR), the Component and Service Registry (CSR), the GEO clearinghouse, and the GEO Portal. The SIR maintains the list of the public standards recognized by the GEO. CSR provides a centralized registry for available Earth Observation resources. The GEO clearinghouse works as a single search facility for GEOSS-wide resources and the GEO Portal provides an integrated Web-based interfaces for users. Since January 2007, researchers at CSISS, GMU have collaborated with officials from the Federal Geographic Data Committee (FGDC) on designing, implementing, maintaining, and upgrading CSR. Currently CSR provides the following capabilities for data providers: user registration, resource registration, and service interface registration. The CSR clients can discover the resources registered in CSR through OGC Catalog for Web (CSW), UUDI, and other standard interfaces. During the resource registration process, providers may define detailed descriptive information for their resources, in particular, the targeted societal benefit area and sub-areas of focus, and the targeted critical Earth Observations.

    Full Text Available Abstract Background Population-based registries have been promoted as an effective method to improve childhood immunization rates, yet rates of registry participation in the private sector are low. We sought to describe, through a national overview, the perspectives of childhood immunization providers in private practice regarding factors associated with participation or non-participation in immunization registries. Methods Two mailed surveys, one for 264 private practices identified as registry non-participants and the other for 971 identified as registry participants, from 15 of the 31 states with population-based statewide immunization registries. Frequency distributions were calculated separately for non-participants and participants regarding the physician-reported factors that influenced decisions related to registry participation. Pearson chi-square tests of independence were used to assess associations among categorical variables. Results Overall response rate was 62% (N = 756. Among non-participants, easy access to records of vaccines provided at other sites (N = 101, 68% and printable immunization records (N = 82, 55% were most often cited as "very important" potential benefits of a registry, while the most commonly cited barriers to participation were too much cost/staff time (N = 36, 38% and that the practice has its own system for recording and monitoring immunizations (N = 35, 37%. Among registry participants, most reported using the registry to input data on vaccines administered (N = 326, 87% and to review immunization records of individual patients (N = 302, 81%. A minority reported using it to assess their practice's immunization coverage (N = 110, 29% or generate reminder/recall notices (N = 54, 14%. Few participants reported experiencing "significant" problems with the registry; the most often cited was cost/staff time to use the registry (N = 71, 20%.

    The aim of the study was to investigate, over time, the incidence of and mortality due to malignant diseases among persons with haemophilia, compared to matched controls. Persons with haemophilia A or B were enrolled via registries at each haemophilia centre, as well as from the National Patient Registry, and were compared to five sex and age-matched controls per patient. Data from the national Cancer Registry were linked to the study participants. A total of 1431 persons with haemophilia and 7150 matched controls were enrolled. Between the years 1972 and 2008, 164 malignancies were reported. The most common type of cancer among patients was prostate cancer, followed by haematologic malignancies, including lymphoma and leukaemia, which were significantly more frequent in patients [n = 35 (2.4%) vs. n = 60 (0.8%); P < 0.001]. Malignancies in bladder and other urinary organs were also significantly different [n = 21 (1.5%) vs. n = 46 (0.6%); P < 0.01]. The overall incidence rate ratio of malignancies per 1000 person-years compared to the controls was 1.3 [95% confidence interval (CI) 1.1, 1.6]. In subgroup analysis, the corresponding incidence rate ratios per 1000 person-years for persons with severe haemophilia was 1.7 (95% CI 0.9, 3.1) and that for mild/moderate haemophilia 1.1 (95% CI 0.8, 1.5). Swedish persons with haemophilia had a significantly higher incidence of malignant diseases than controls. These were primarily haematologic malignancies and cancer in urinary organs, and the difference independent of any co-infections with HIV and/or viral hepatitis. The findings indicate the importance of further studies and close follow-up of malignancies in persons with haemophilia. PMID:26974329

  12. Correcting for catchment area nonresidency in studies based on tumor-registry data

    International Nuclear Information System (INIS)

    We discuss the effect of catchment area nonresidency on estimates of cancer incidence from a tumor-registry-based cohort study and demonstrate that a relatively simple correction is possible in the context of Poisson regression analysis if individual residency histories or the probabilities of residency are known. A comparison of a complete data maximum likelihood analysis with several Poisson regression analyses demonstrates the adequacy of the simple correction in a large simulated data set. We compare analyses of stomach-cancer incidence from the Radiation Effects Research Foundation tumor registry with and without the correction. We also discuss some implications of including cases identified only on the basis of death certificates. (author)

    In 2010, the American College of Medical Toxicology (ACMT) established its Case Registry, the Toxicology Investigators Consortium (ToxIC). All cases are entered prospectively and include only suspected and confirmed toxic exposures cared for at the bedside by board-certified or board-eligible medical toxicologists at its participating sites. The primary aims of establishing this Registry include the development of a realtime toxico-surveillance system in order to identify and describe current or evolving trends in poisoning and to develop a research tool in toxicology. ToxIC allows for extraction of data from medical records from multiple sites across a national and international network. All cases seen by medical toxicologists at participating institutions were entered into the database. Information characterizing patients entered in 2012 was tabulated and data from the previous years including 2010 and 2011 were included so that cumulative numbers and trends could be described as well. The current report includes data through December 31st, 2012. During 2012, 38 sites with 68 specific institutions contributed a total of 7,269 cases to the Registry. The total number of cases entered into the Registry at the end of 2012 was 17,681. Emergency departments remained the most common source of consultation in 2012, accounting for 61 % of cases. The most common reason for consultation was for pharmaceutical overdose, which occurred in 52 % of patients including intentional (41 %) and unintentional (11 %) exposures. The most common classes of agents were sedative-hypnotics (1,422 entries in 13 % of cases) non-opioid analgesics (1,295 entries in 12 % of cases), opioids (1,086 entries in 10 % of cases) and antidepressants (1,039 entries in 10 % of cases). N-acetylcysteine (NAC) was the most common antidote administered in 2012, as it was in previous years, followed by the opioid antagonist naloxone, sodium bicarbonate, physostigmine and flumazenil.

  18. Can prophylactic breast irradiation contribute to cardiac toxicity in patients with prostate cancer receiving androgen suppressing drugs?

    International Nuclear Information System (INIS)

    Androgen suppression treatment (AST) might increase the risk of cardiac morbidity in prostate cancer patients. Possible explanations were provided, however, they disregard the potential contribution of prophylactic radiotherapy to the mamillary regions (PMRT, prescribed to avoid gynecomastia). We studied the exposure of the heart in a typical electron beam PMRT setting by evaluating computed tomography (CT) scans in 40 non-cancer patients (age 65 and 75 years in 50% each) and 17 prostate cancer patients. Five of the younger, 7 of the older and 4 of the cancer patients had significant cardiac disease. The median distance between skin and outer heart contour decreased with age. In all three groups, patients with cardiac morbidity had smaller distances. When using the CT-determined PMRT beam energy, 10% of the younger, 15% of the older and none of the prostate cancer patients would receive approximately 50% of the prescription dose to a part of the heart (2 had no history of cardiac disease). When using the clinically rather than CT-determined beam energy, as often done in daily practice, an additional 12.5% of the non-cancer and 12% of the prostate cancer patients would be exposed to comparably high doses. The present data provide preliminary evidence that PMRT might be a factor that contributes to cardiac side effects. Previous studies that established a relationship between AST and cardiac morbidity did not include information on delivery of PMRT

    2010-01-01

    Full Text Available Digital ulcers are a very frequent complication of systemic sclerosis affecting about half of the SSc patients, and about 75% of the affected patients have their first DU episode within 5 years from their first non-Raynaud symptom. The lack of adequate classification criteria as well as the lack of knowledge of the development of DU have contributed to the opening of specific registries to better understand the natural history of these lesions. For these reason, specific disease registries play a fundamental role in this field of research. Thanks to the systematic collection of data and their subsequent analysis and comparison between different cohorts, it is possible to improve understanding of the underlying trigger mechanisms of DU development and to determine temporal trends. In the future, the development of recommendations for the management of DU remains of pivotal importance to prevent DU development and obtain rapid healing as well as reduction of pain and disability.

  2. Contribution of MIBI 99mTc mammary scintigraphy in mammary cancer detection

    International Nuclear Information System (INIS)

    Recent publications indicate the interest in 99mTc - SESTA-MIBI in diagnosing mammary cancers. The goal of this paper was to study the feasibility of this method and define its place relative to the classical tripod: mammography, echography, cyto-puncture. The mammary scintigraphy is achieved, in condition ventral-decubitus at 10 minutes after the injection of 20 mCi of SESTA-MIBI, in 100 patients for which a surgery decision was made. Ten minute incidences from the left, right and front sides were achieved. A visual score ranging from G1 to G4 was established: G1 - no anomalous fixation; G2 - slight fixation of irregular shape; G3 - moderate well-defined fixation; G4 - intense circular fixation. The final diagnosis is given by histology. Results with the score ranging from G1 to G4 for five diagnosis types are given. By considering G3 and G4 as positive to biopsy the sensitivity found was 91.2%; the specificity, 62.8%; the positive predicting value, 76.4% and the VPN, 84.4%. Five falsely negative cancers correspond to micro-calcification sub-centimeter lesions. In conclusion, the contribution of the mammary scintigraphy consists in identification of positive MIBI lesions having a uncertain and/or ensuring ensuring and multi-focal lesions for the cases in which the tripod indicate a single lesion. Making evident these multi-focal lesions allows establishing a surgical operation scheme which will guide an enlarged extirpation

    2014-03-01

    Full Text Available Despite evidence that kinesin family member 14 (KIF14 can serve as a prognostic biomarker in various solid tumors, how it contributes to tumorigenesis remains unclear. We observed that experimental decrease in KIF14 expression increases docetaxel chemosensitivity in estrogen receptor–negative/progesterone receptor–negative/human epidermal growth factor receptor 2-negative, “triple-negative” breast cancers (TNBC. To investigate the oncogenic role of KIF14, we used noncancerous human mammary epithelial cells and ectopically expressed KIF14 and found increased proliferative capacity, increased anchorage-independent grown in vitro, and increased resistance to docetaxel but not to doxorubicin, carboplatin, or gemcitabine. Seventeen benign breast biopsies of BRCA1 or BRCA2 mutation carriers showed increased KIF14 mRNA expression by fluorescence in situ hybridization compared to controls with no known mutations in BRCA1 or BRCA2, suggesting increased KIF14 expression as a biomarker of high-risk breast tissue. Evaluation of 34 cases of locally advanced TNBC showed that KIF14 expression significantly correlates with chemotherapy-resistant breast cancer. KIF14 knockdown also correlates with decreased AKT phosphorylation and activity. Live-cell imaging confirmed an insulin-induced temporal colocalization of KIF14 and AKT at the plasma membrane, suggesting a potential role of KIF14 in promoting activation of AKT. An experimental small-molecule inhibitor of KIF14 was then used to evaluate the potential anticancer benefits of downregulating KIF14 activity. Inhibition of KIF14 shows a chemosensitizing effect and correlates with decreasing activation of AKT. Together, these findings show an early and critical role for KIF14 in the tumorigenic potential of TNBC, and therapeutic targeting of KIF14 is feasible and effective for TNBC.

Seventeen benign breast biopsies of BRCA1 or BRCA2 mutation carriers showed increased KIF14 mRNA expression by fluorescence in situ hybridization compared to controls with no known mutations in BRCA1 or BRCA2, suggesting increased KIF14 expression as a biomarker of high-risk breast tissue. Evaluation of 34 cases of locally advanced TNBC showed that KIF14 expression significantly correlates with chemotherapy-resistant breast cancer. KIF14 knockdown also correlates with decreased AKT phosphorylation and activity. Live-cell imaging confirmed an insulin-induced temporal colocalization of KIF14 and AKT at the plasma membrane, suggesting a potential role of KIF14 in promoting activation of AKT. An experimental small-molecule inhibitor of KIF14 was then used to evaluate the potential anticancer benefits of downregulating KIF14 activity. Inhibition of KIF14 shows a chemosensitizing effect and correlates with decreasing activation of AKT. Together, these findings show an early and critical role for KIF14 in the tumorigenic potential of TNBC, and therapeutic targeting of KIF14 is feasible and effective for TNBC. PMID:24784001

    Despite the fact that radiation is one of the standard therapies in the treatment of patients with oral cancer, tumours can recur even in the early stages of the disease, negatively impacting prognosis and quality of life. We previously found that CD11b+ bone marrow-derived cells (BMDCs) were recruited into human glioblastoma multiforme (GBM), leading to re-organization of the vasculature and tumour regrowth. However, it is not yet known how these cells contribute to tumour vascularization. In the present study, we investigated the role of infiltrating CD11b+ myeloid cells in the vascularization and recurrence of oral squamous cell carcinoma (OSCC). In a xenograft mouse model, local irradiation caused vascular damage and hypoxia in the tumour and increased infiltration of CD11b+ myeloid cells. These infiltrating cells showed characteristics of M2 macrophages (M2Mφs) and are associated with the promotion of vascularization. M2Mφs promoted tumour progression in recurrence after irradiation compared to non-irradiated tumours. In addition, we found that CD11b+ myeloid cells, as well as CD206+ M2Mφs, are increased during recurrence after radiotherapy in human OSCC specimens. Our findings may lead to the development of potential clinical biomarkers or treatment targets in irradiated OSCC patients. PMID:27271009

  7. HIF-1 and NDRG2 contribute to hypoxia-induced radioresistance of cervical cancer Hela cells

    International Nuclear Information System (INIS)

    Hypoxia inducible factor 1 (HIF-1), the key mediator of hypoxia signaling pathways, has been shown involved in hypoxia-induced radioresistance. However, the underlying mechanisms are unclear. The present study demonstrated that both hypoxia and hypoxia mimetic cobalt chloride could increase the radioresistance of human cervical cancer Hela cells. Meanwhile, ectopic expression of HIF-1 could enhance the resistance of Hela cells to radiation, whereas knocking-down of HIF-1 could increase the sensitivity of Hela cells to radiation in the presence of hypoxia. N-Myc downstream-regulated gene 2 (NDRG2), a new HIF-1 target gene identified in our lab, was found to be upregulated by hypoxia and radiation in a HIF-1-dependent manner. Overexpression of NDRG2 resulted in decreased sensitivity of Hela cells to radiation while silencing NDRG2 led to radiosensitization. Moreover, NDRG2 was proved to protect Hela cells from radiation-induced apoptosis and abolish radiation-induced upregulation of Bax. Taken together, these data suggest that both HIF-1 and NDRG2 contribute to hypoxia-induced tumor radioresistance and that NDRG2 acts downstream of HIF-1 to promote radioresistance through suppressing radiation-induced Bax expression. It would be meaningful to further explore the clinical application potential of HIF-1 and NDRG2 blockade as radiosensitizer for tumor therapy.

    Zinc is an essential trace element and catalytic/structural component used by many metalloenzymes and transcription factors. Recent studies indicate a possible correlation of zinc levels with the cancer risk; however, the exact role of zinc and zinc transporters in cancer progression is unknown. We have observed that a zinc transporter, ZIP4 (SLC39A4), was substantially overexpressed in 16 of 17 (94%) clinical pancreatic adenocarcinoma specimens compared with the surrounding normal tissues, and ZIP4 mRNA expression was significantly higher in human pancreatic cancer cells than human pancreatic ductal epithelium (HPDE) cells. This indicates that aberrant ZIP4 up-regulation may contribute to the pancreatic cancer pathogenesis and progression. We studied the effects of ZIP4 overexpression in pancreatic cancer cell proliferation in vitro and pancreatic cancer progression in vivo. We found that forced expression of ZIP4 increased intracellular zinc levels, increased cell proliferation by 2-fold in vitro, and significantly increased tumor volume by 13-fold in the nude mice model with s.c. xenograft compared with the control cells. In the orthotopic nude mice model, overexpression of ZIP4 not only increased the primary tumor weight (7.2-fold), it also increased the peritoneal dissemination and ascites incidence. Moreover, increased cell proliferation and higher zinc content were also observed in the tumor tissues that overexpressed ZIP4. These data reveal an important outcome of aberrant ZIP4 expression in contributing to pancreatic cancer pathogenesis and progression. It may suggest a therapeutic strategy whereby ZIP4 is targeted to control pancreatic cancer growth. PMID:18003899

    In order to assess the needs of knowledge about surveillance and registries in Italy and to prepare a proposal for the advancement of monitoring and recording capacity, a working group led by the Italian Association of Epidemiology and composed by the University of Turin, the Institute of Health and Agenas, carried out a survey of definitions and approaches used in public health and consulted the main Italian experts in surveillance and registries. Some of the reflections developed in this project are presented, to assess to which extent they are adaptable to the prospects the program PRIER aims to. Different aspects of the issue are analyzed: from the frame work necessary to identify information needs and how to improve the ability to measure and types of definitions and taxonomies of the registers, to the implications of the choices about what to include in registries on regulation of the instruments and investment priorities for new registries and surveillance.

    Zhu, Yuandong; Gladyshev, Pavel; James, Joshua

    The Microsoft Windows registry is an important resource in digital forensic investigations. It contains information about operating system configuration, installed software and user activity. Several researchers have focused on the forensic analysis of the Windows registry, but a robust method for associating past events with registry data values extracted from Windows restore points is not yet available. This paper proposes a novel algorithm for analyzing the most recently used (MRU) keys found in consecutive snapshots of the Windows registry. The algorithm compares two snapshots of the same MRU key and identifies data values within the key that have been updated in the period between the two snapshots. User activities associated with the newly updated data values can be assumed to have occurred during the period between the two snapshots.

  13. The United States Transuranium and Uranium Registries

    International Nuclear Information System (INIS)

    The United States Transuranium and Uranium Registries are unique parallel research programs devoted to the study of the actinide elements in man. The primary mission of the Registries is to verify and ensure the adequacy and applicability of radiation protection standards for the actinides. To accomplish this task, the Registries utilize tissues obtained postmortem from informed volunteer donors with confirmed or high likelihood of exposure to plutonium, americium, or other actinides. These are collected at autopsy and radiochemically analyzed for actinide content. The results, along with relevant details of occupational and exposure history, medical history and health physics data are used to determine the distribution, biokinetics and dosimetry of the actinides in humans, and to correlate estimates of deposition and dose made during life with postmortem findings. Other important applications of the Registries' research is scaling of animal studies to man and validation or refinement of biokinetic models on which the safety standards are based

  14. Increased diacylglycerol kinase ζ expression in human metastatic colon cancer cells augments Rho GTPase activity and contributes to enhanced invasion

    International Nuclear Information System (INIS)

    Unraveling the signaling pathways responsible for the establishment of a metastatic phenotype in carcinoma cells is critically important for understanding the pathology of cancer. The acquisition of cell motility is a key property of metastatic tumor cells and is a prerequisite for invasion. Rho GTPases regulate actin cytoskeleton reorganization and the cellular responses required for cell motility and invasion. Diacylglycerol kinase ζ (DGKζ), an enzyme that phosphorylates diacylglycerol to yield phosphatidic acid, regulates the activity of the Rho GTPases Rac1 and RhoA. DGKζ mRNA is highly expressed in several different colon cancer cell lines, as well as in colon cancer tissue relative to normal colonic epithelium, and thus may contribute to the metastatic process. To investigate potential roles of DGKζ in cancer metastasis, a cellular, isogenic model of human colorectal cancer metastatic transition was used. DGKζ protein levels, Rac1 and RhoA activity, and PAK phosphorylation were measured in the non-metastatic SW480 adenocarcinoma cell line and its highly metastatic variant, the SW620 line. The effect of DGKζ silencing on Rho GTPase activity and invasion through Matrigel-coated Transwell inserts was studied in SW620 cells. Invasiveness was also measured in PC-3 prostate cancer and MDA-MB-231 breast cancer cells depleted of DGKζ. DGKζ protein levels were elevated approximately 3-fold in SW620 cells compared to SW480 cells. There was a concomitant increase in active Rac1 in SW620 cells, as well as substantial increases in the expression and phosphorylation of the Rac1 effector PAK1. Similarly, RhoA activity and expression were increased in SW620 cells. Knockdown of DGKζ expression in SW620 cells by shRNA-mediated silencing significantly reduced Rac1 and RhoA activity and attenuated the invasiveness of SW620 cells in vitro. DGKζ silencing in highly metastatic MDA-MB-231 breast cancer cells and PC-3 prostate cancer cells also significantly attenuated

A patient registry is a tool that documents the natural history of target diseases. Clinicians and researchers use registries to monitor patient comorbidities, care procedures and processes, and treatment effectiveness for the purpose of improving care quality. Enactments of the Affordable Care Act 2010 and the Mental Health Parity and Addiction Equity Act 2008 open opportunities for many substance users to receive treatment services in general medical settings. An increased number of patients with a wide spectrum of SUD will initially receive services with a chronic disease management approach in primary care. The establishment of computer-based SUD patient registries can be assisted by wide adoption of electronic health record systems. The linkage of SUD patient registries with electronic health record systems can facilitate the advancement of SUD treatment research efforts and improve patient care.

    Background This article provides a summary of the 2011 ERA–EDTA Registry Annual Report (available at www.era-edta-reg.org). Methods Data on renal replacement therapy (RRT) for end-stage renal disease (ESRD) from national and regional renal registries in 30 countries in Europe and bordering the Mediterranean Sea were used. From 27 registries, individual patient data were received, whereas 17 registries contributed data in aggregated form. We present the incidence and prevalence of RRT, and renal transplant rates in 2011. In addition, survival probabilities and expected remaining lifetimes were calculated for those registries providing individual patient data. Results The overall unadjusted incidence rate of RRT in 2011 among all registries reporting to the ERA–EDTA Registry was 117 per million population (pmp) (n = 71.631). Incidence rates varied from 24 pmp in Ukraine to 238 pmp in Turkey. The overall unadjusted prevalence of RRT for ESRD on 31 December 2011 was 692 pmp (n = 425 824). The highest prevalence was reported by Portugal (1662 pmp) and the lowest by Ukraine (131 pmp). Among all registries, a total of 22 814 renal transplantations were performed (37 pmp). The highest overall transplant rate was reported from Spain, Cantabria (81 pmp), whereas the highest rate of living donor transplants was reported from Turkey (39 pmp). For patients who started RRT between 2002 and 2006, the unadjusted 5-year patient survival on RRT was 46.8% [95% confidence interval (CI) 46.6–47.0], and on dialysis 39.3% (95% CI 39.2–39.4). The unadjusted 5-year patient survival after the first renal transplantation performed between 2002 and 2006 was 86.7% (95% CI 86.2–87.2) for kidneys from deceased donors and 94.3% (95% CI 93.6–95.0) for kidneys from living donors.

    In this paper, the factors involved in the assessment of the relative contributions of mortality from cancer of individual organs are explored, thus providing a basis for new estimates of weighting factors to be made by the ICRP in assessing the total detriment for a given radiation dose. Systems of site-specific relative weights for cancer mortality risk due to radiation exposure were examined with respect to the effects of age, sex, projection model, population characteristics as represented by baseline, cause-specific mortality rates and choice between probability of untimely death and expected loss of life span as a measure of health detriment.

  20. Dairy cattle serum and milk factors contributing to the risk of colon and breast cancers.

    The analysis of published epidemiological data on colon and breast cancer reveals a remarkable concordance for most regions of the world. A low incidence for both cancers has been recorded in Mongolia and Bolivia. Discrepant data, however, have been reported for India, Japan and Korea. In India, the incidence of breast cancer is significantly higher than for colon cancer, in Japan and Korea colon cancer exceeds by far the rate of breast cancer. Here, studies are summarized pointing to a species-specific risk for colon cancer after consumption of beef originating from dairy cattle. Uptake of dairy products of Bos taurus-derived milk cattle, particularly consumed at early age, is suggested to represent one of the main risk factors for the development of breast cancer. A recent demonstration of reduced breast cancer rates in individuals with lactose intolerance (Ji et al., Br J Cancer 2014; 112:149-52) seems to be in line with this interpretation. Species-specific risk factors for these cancers are compatible with the transmission of different infectious factors transferred via meat or dairy products. Countries with discordant rates of colon and breast cancer reveal a similar discordance between meat and milk product consumption of dairy cattle. The recent isolation of a larger number of novel presumably viral DNAs from serum, meat and dairy products of healthy dairy cows, at least part of them infectious for human cells, deserves further investigation. Systemic infections early in life, resulting in latency and prevention of subsequent infections with the same agent by neutralizing antibodies, would require reconsideration of ongoing prospective studies conducted in the adult population.

    The plasmacytoma variant translocation 1 gene (PVT1) is an lncRNA that has been designated as an oncogene due to its contribution to the phenotype of multiple cancers. Although the mechanism by which PVT1 influences disease processes has been studied in multiple cancer types, its role in cervical tumorigenesis remains unknown. Thus, the present study was designed to investigate the role of PVT1 in cervical cancer in vitro and in vivo. PVT1 expression was measured by quantitative PCR (qPCR) in 121 invasive cervical carcinoma (ICC) samples, 30 normal cervix samples, and cervical cell lines. Functional assays were carried out using both siRNA and LNA-mediated knockdown to examine PVT1's effects on cervical cancer cell proliferation, migration and invasion, apoptosis, and cisplatin resistance. Our results demonstrate that PVT1 expression is significantly increased in ICC tissue versus normal cervix and that higher expression of PVT1 correlates with poorer overall survival. In cervical cancer cell lines, PVT1 knockdown resulted in significantly decreased cell proliferation, migration and invasion, while apoptosis and cisplatin cytotoxicity were significantly increased in these cells. Finally, we show that PVT1 expression is augmented in response to hypoxia and immune response stimulation and that this lncRNA associates with the multifunctional and stress-responsive protein, Nucleolin. Collectively, our results provide strong evidence for an oncogenic role of PVT1 in cervical cancer and lend insight into potential mechanisms by which PVT1 overexpression helps drive cervical carcinogenesis.

  4. Dormancy of cancer cells with suppression of AKT activity contributes to survival in chronic hypoxia.

    Full Text Available A hypoxic microenvironment in tumors has been recognized as a cause of malignancy or resistance to various cancer therapies. In contrast to recent progress in understanding the acute response of cancer cells to hypoxia, the characteristics of tumor cells in chronic hypoxia remain elusive. We have identified a pancreatic cancer cell line, AsPC-1, that is exceptionally able to survive for weeks under 1% oxygen conditions while most tested cancer cell lines die after only some days under these conditions. In chronic hypoxia, AsPC-1 cells entered a state of dormancy characterized by no proliferation, no death, and metabolic suppression. They reversibly switched to active status after being placed again in optimal culture conditions. ATP turnover, an indicator of energy demand, was markedly decreased and accompanied by reduced AKT phosphorylation. Forced activation of AKT resulted in increased ATP turnover and massive cell death in vitro and a decreased number of dormant cells in vivo. In contrast to most cancer cell lines, primary-cultured colorectal cancer cells easily entered the dormant status with AKT suppression under hypoxia combined with growth factor-depleted conditions. Primary colorectal cancer cells in dormancy were resistant to chemotherapy. Thus, the ability to survive in a deteriorated microenvironment by entering into dormancy under chronic hypoxia might be a common property among cancer cells. Targeting the regulatory mechanism inducing this dormant status could provide a new strategy for treating cancer.

    Breast cancer is the most common female malignancy and the leading cancer mortality cause among Algerian women. Germline mutations in the BRCA1 and BRCA2 genes in patients with early-onset breast cancer have not been clearly identified within the Algerian population. It is necessary to study the BRCA1/2 genes involvement in the Algerian breast cancer occurrence. We performed this study to define germline mutations in BRCA1/2 and their implication in breast cancer among young women from eastern Algeria diagnosed or treated with primary invasive breast cancer at the age of 40 or less who were referred to Anti-Cancer Center of Setif, Algeria. Case series were unselected for family history. Eight distinct pathogenic mutations were identified in eight unrelated families. Three deleterious mutations and one large genomic rearrangement involving deletion of exon 2 were found in BRCA1 gene. In addition, four mutations within the BRCA2 gene and one large genomic rearrangement were identified. Novel mutation was found among Algerian population. Moreover, five variants of uncertain clinical significance and favor polymorphisms were identified. Our data suggest that BRCA1/2 mutations are responsible for a significant proportion of breast cancer in Algerian young women. PMID:26997744

    The apoptosis linked gene-2 (ALG-2), discovered as a proapoptotic calcium binding protein, has recently been found upregulated in lung cancer tissue indicating that this protein may play a role in the pathology of cancer cells and/or may be a tumor marker. Using immunohistochemistry on tissue...... microarrays we analysed the expression of ALG-2 in 7371 tumor tissue samples of various origin as well as in 749 normal tissue samples. Most notably, ALG-2 was upregulated in mesenchymal tumors. No correlation was found between ALG-2 staining intensity and survival of patients with lung, breast or colon...... cancer. siRNA mediated ALG-2 downregulation led to a significant reduction in viability of HeLa cells indicating that ALG-2 may contribute to tumor development and expansion....

  7. Clinical manifestations and radiological features may contribute to the early diagnosis of radiation-induced sarcoma after breast cancer

    International Nuclear Information System (INIS)

    Aim: To describe the clinical manifestations and radiological features contributing to the early diagnosis of radiation-induced sarcoma (RIS) after radiotherapy for breast cancer. Materials and methods: This retrospective analysis included four typical cases of RIS diagnosed at Affiliated Hospital of Academy of Military Medical Sciences between 1980 and 2013. Patient and imaging characteristics, treatment modalities, and outcomes were extracted from patients' medical records. Two pathologists reviewed all histological slides. Results: All four cases were misdiagnosed and treated for several months as cases of breast cancer relapse. CT using the bone-window setting and three-dimensional reconstructions clearly displayed bone tumours of RIS in three cases. Skin alterations were observed in all cases. At the time of RIS diagnosis, three patients were free of breast cancer. In one patient with bilateral breast cancer and lung metastasis, chemotherapy resulted in complete remission of the metastasis, but RIS progression. No RIS in this series responded to chemotherapy or endocrine therapy. Conclusions: Abnormalities appearing in the radiation field long after RT should alert clinicians to the potential development of RIS. Careful physical examination and follow-up imaging studies are necessary. The presence of skin alterations, bone tumours at CT or radiography, and poor response to anti-cancer drugs may contribute to the early detection of RIS. Biopsy should be performed immediately when RIS is suspected. - Highlights: • Abnormalities in the radiation field should alert to the development of RIS. • Skin alterations and bone tumors on images may contribute to the early detection. • Biopsy should be performed immediately when Radiation-induced sarcoma is suspected

    The use of large-scale national databases for observational research in orthopaedic surgery has grown substantially in the last decade, and the data sets can be categorized as either administrative claims or clinical registries. Clinical registries contain secondary data on patients with a specific diagnosis or procedure. The data are typically used for patient outcome surveillance to improve patient safety and health-care quality. Registries used in orthopaedic research exist at the regional, national, and international levels, and many were designed to specifically collect outcomes relevant to orthopaedics, such as short-term surgical complications, longer-term outcomes (implant survival or reoperations), and patient-reported outcomes. Although heterogeneous, clinical registries-in contrast to claims data-typically have a more robust list of variables, with relatively precise prospective data input, management infrastructure, and reporting systems. Some weaknesses of clinical registries include a smaller number of patients, inconstant follow-up duration, and use of sampling methods that may limit generalizability. Within the U.S., national joint registry adoption has lagged international joint registries. Given the changing health-care environment, it is likely that clinical registries will provide valuable information that has the potential to influence clinical practice improvement and health-care policy in the future.

    Full Text Available Abstract Background Genomic copy number changes and regional alterations in epigenetic states have been linked to grade in breast cancer. However, the relative contribution of specific alterations to the pathology of different breast cancer subtypes remains unclear. The heterogeneity and interplay of genomic and epigenetic variations means that large datasets and statistical data mining methods are required to uncover recurrent patterns that are likely to be important in cancer progression. Results We employed ridge regression to model the relationship between regional changes in gene expression and proliferation. Regional features were extracted from tumour gene expression data using a novel clustering method, called genomic distance entrained agglomerative (GDEC clustering. Using gene expression data in this way provides a simple means of integrating the phenotypic effects of both copy number aberrations and alterations in chromatin state. We show that regional metagenes derived from GDEC clustering are representative of recurrent regions of epigenetic regulation or copy number aberrations in breast cancer. Furthermore, detected patterns of genomic alterations are conserved across independent oestrogen receptor positive breast cancer datasets. Sequential competitive metagene selection was used to reveal the relative importance of genomic regions in predicting proliferation rate. The predictive model suggested additive interactions between the most informative regions such as 8p22-12 and 8q13-22. Conclusions Data-mining of large-scale microarray gene expression datasets can reveal regional clusters of co-ordinate gene expression, independent of cause. By correlating these clusters with tumour proliferation we have identified a number of genomic regions that act together to promote proliferation in ER+ breast cancer. Identification of such regions should enable prioritisation of genomic regions for combinatorial functional studies to pinpoint

    Full Text Available Newly identified nuocytes or group 2 innate lymphoid cells (ILC2s play an important role in Th2 cell mediated immunity such as protective immune responses to helminth parasites, allergic asthma, and chronic rhinosinusitis. However, the contributions of ILC2s in the occurrence and development of cancer remain unknown. Our previous study found that there was a predominant Th2 phenotype in patients with gastric cancer. In this study, the ILC2s related genes or molecules in PBMC from patients with gastric cancer were measured, and the potential correlation between them was analyzed. The expression levels of RORα, GATA3, T1/ST2, IL-17RB, CRTH2, IL-33, IL-5, and IL-4 mRNA were significantly increased in patients, but no significant changes were found in ICOS, CD45, and IL-13 expression, and there was a positive correlation between RORα or IL-13 and other related factors, such as ICOS and CD45. The increased frequency of ILC2s was also found in PBMC of patients by flow cytometry. In addition, the mRNA of Arg1 and iNOS were also significantly increased in patients. These results suggested that there are polarized ILC2s in gastric cancer patients which might contribute to immunosuppressive microenvironment and closely related to the upregulation of MDSCs and M2 macrophages.

    The histone methyltransferase NSD2/WHSC1/MMSET is overexpressed in a number of solid tumors but its contribution to the biology of these tumors is not well understood. Here, we describe that NSD2 contributes to the proliferation of a subset of lung cancer cell lines by supporting oncogenic RAS transcriptional responses. NSD2 knock down combined with MEK or BRD4 inhibitors causes co-operative inhibitory responses on cell growth. However, while MEK and BRD4 inhibitors converge in the downregulation of genes associated with cancer-acquired super-enhancers, NSD2 inhibition affects the expression of clusters of genes embedded in megabase-scale regions marked with H3K36me2 and that contribute to the RAS transcription program. Thus, combinatorial therapies using MEK or BRD4 inhibitors together with NSD2 inhibition are likely to be needed to ensure a more comprehensive inhibition of oncogenic RAS-driven transcription programs in lung cancers with NSD2 overexpression.

    2013-03-01

    Fatigue is one of the most common and distressing side effects of cancer and its treatment, and may persist for years after treatment completion in otherwise healthy survivors. Guided by basic research on neuro-immune interactions, a growing body of research has examined the hypothesis that cancer-related fatigue is driven by activation of the pro-inflammatory cytokine network. In this review, we examine the current state of the evidence linking inflammation and cancer-related fatigue, drawing from recent human research and from experimental animal models probing effects of cancer and cancer treatment on inflammation and fatigue. In addition, we consider two key questions that are currently driving research in this area: what are the neural mechanisms of fatigue, and what are the biological and psychological factors that influence the onset and/or persistence of inflammation and fatigue in cancer patients and survivors? Identification of the mechanisms driving cancer-related fatigue and associated risk factors will facilitate the development of targeted interventions for vulnerable patients. PMID:22776268

    The National Mental Health Registry (NMHR) collects information about patients with mental disorder in Malaysia. This information allows us to estimate the incidence of selected mental disorders, and to evaluate risk factors and treatment in the country. The National Mental Health Registry (NMHR) presented its first report in 2004, a year after its establishment. The report focused on schizophrenia as a pioneer project for the National Mental Health Registry. The development of the registry has progressed with data collected from government-based facilities, the academia and the private sector. The 2003-2005 report was recently published and distributed. Since then the registry has progressed to include suicides and other mental illnesses such as depression. The NMHR Report 2003-2005 provides detailed information about the profile of persons with Schizophrenia who presented for the first time to various psychiatry and mental health providers throughout Malaysia. More detailed description regarding pharmacotherapy is reported and few cross tabulations done in an effort to provide better understanding and more clinically meaningful reports. PMID:19227671

    Ovarian cancer is the most lethal of all gynaecological cancers among women. Serum CA125 is the only biomarker that is used routinely and there is a need for further complementary biomarkers both in terms of sensitivity and specificity. N-glycosylation changes in ovarian cancer serum glycoproteins include a decrease in galactosylation of IgG and an increase in sialyl Lewis X (SLex) on haptoglobin β-chain, α1-acid glycoprotein and α1-antichymotrypsin. These changes are also present in chronic ...

  16. STK31 is a cell-cycle regulated protein that contributes to the tumorigenicity of epithelial cancer cells.

    Directory of Open Access Journals (Sweden)

    Pao-Lin Kuo

    Full Text Available Serine/threonine kinase 31 (STK31 is one of the novel cancer/testis antigens for which its biological functions remain largely unclear. Here, we demonstrate that STK31 is overexpressed in many human colorectal cancer cell lines and tissues. STK31 co-localizes with pericentrin in the centrosomal region throughout all phases of the cell cycle. Interestingly, when cells undergo mitosis, STK31 also localizes to the centromeres, central spindle, and midbody. This localization behavior is similar to that of chromosomal passenger proteins, which are known to be the important players of the spindle assembly checkpoint. The expression of STK31 is cell cycle-dependent through the regulation of a putative D-box near its C-terminal region. Ectopically-expressed STK31-GFP increases cell migration and invasive ability without altering the proliferation rate of cancer cells, whereas the knockdown expression of endogenous STK31 by lentivirus-derived shRNA results in microtubule assembly defects that prolong the duration of mitosis and lead to apoptosis. Taken together, our results suggest that the aberrant expression of STK31 contributes to tumorigenicity in somatic cancer cells. STK31 might therefore act as a potential therapeutic target in human somatic cancers.

Transcriptionally active HIF-1 and HIF-2 regulate overlapping sets of target genes, and only few HIF-2 specific target genes are known so far. Here we investigated oxygen-regulated expression of Wnt-1 induced signaling protein 2 (WISP-2, which has been reported to attenuate the progression of breast cancer. WISP-2 was hypoxically induced in low-invasive luminal-like breast cancer cell lines at both the messenger RNA and protein levels, mainly in a HIF-2α-dependent manner. HIF-2-driven regulation of the WISP2 promoter in breast cancer cells is almost entirely mediated by two phylogenetically and only partially conserved functional hypoxia response elements located in a microsatellite region upstream of the transcriptional start site. High WISP-2 tumor levels were associated with increased HIF-2α, decreased tumor macrophage density, and a better prognosis. Silencing WISP-2 increased anchorage-independent colony formation and recovery from scratches in confluent cell layers of normally low-invasive MCF-7 cancer cells. Interestingly, these changes in cancer cell aggressiveness could be phenocopied by HIF-2α silencing, suggesting that direct HIF-2-mediated transcriptional induction of WISP-2 gene expression might at least partially explain the association of high HIF-2α tumor levels with prolonged overall survival of patients with breast cancer.Keywords: invasion, metastasis, motility, oxygen, tumor, transcriptional

    Full Text Available BACKGROUND: Genetic variation in glutathione S-transferases (GSTs may contribute to lung cancer risk. Many studies have investigated the correlation between the Glutathione S-transferase T1 (GSTT1 null genotype and lung cancer risk in Asian population but yielded inconclusive results. METHODOLOGY/PRINCIPAL FINDINGS: We performed a meta-analysis of 23 studies including 4065 cases and 5390 controls. We assessed the strength of the association of GSTT1 with lung cancer risk and performed sub-group analyses by source of controls, smoking status, histological types, and sample size. A statistically significant correlation between GSTT1 null genotype and lung cancer in Asian population was observed (OR = 1.28, 95% CI = 1.10, 1.49; Pheterogeneity<0.001 and I(2 = 62.0%. Sub-group analysis revealed there was a statistically increased lung cancer risk in ever-smokers who carried the GSTT1 null genotype (OR = 1.94, 95% CI = 1.27, 2.96; P heterogeneity = 0.02 and I(2 = 58.1%. It was also indicated that GSTT1 null genotype could increase lung cancer risk among population-based studies (OR = 1.25, 95% CI = 1.04, 1.50; Pheterogeneity = 0.003 and I(2 = 56.8%. The positive association was also found in studies of sample size (≤500 participants (OR = 1.34, 95% CI = 1.10, 1.62; Pheterogeneity<0.001 and I(2 = 65.4%. CONCLUSIONS: These meta-analysis results suggest that GSTT1 null genotype is associated with a significantly increased risk of lung cancer in Asian population.

  7. The contribution of tumour-derived exosomes to the hallmarks of cancer.

    Meehan, Katie; Vella, Laura J

    2016-01-01

    Exosomes are small, biologically active extracellular vesicles and over the last decade, both stromal and tumour-derived exosomes (TDE) have been implicated in cancer onset, progression and metastases. Cancer is a complex disease that is underpinned by several "cancer hallmarks", originally described by Hanahan and Weinberg in 2000 and then revised in 2011. The hallmarks of cancer comprise six biological capabilities, along with two emerging hallmarks and two enabling characteristics that facilitate tumour growth and metastatic dissemination. Ample evidence supports a clear role for TDE in four of the original biological hallmarks (sustaining proliferative signalling, resisting cell death, inducing angiogenesis and activating invasion and metastases). A less-defined role exists for TDE in evading growth suppressors, and currently, there is no evidence to suggest a role for TDE in enabling replicative immortality. TDE are intimately involved in the newly defined hallmarks of cancer and enabling characteristics, most evidently in immune inhibition and tumour-promoting inflammation, which ultimately enable escape from immune destruction and tumour progression. Herein, we discuss the role of TDE in the context of the hallmarks and enabling characteristics of cancer as defined by Hanahan and Weinberg. PMID:26479834

    The isocitrate dehydrogenase (IDH) family of enzymes comprises of the key functional metabolic enzymes in the Krebs cycle that catalyze the conversion of isocitrate to α-ketoglutarate (α-KG). α-KG acts as a cofactor in the conversion of 5-methylcytosine (5mC) to 5-hydroxymethylcytosine (5hmC). However, the relationship between 5hmC and IDH in gastric cancer remains unclear. Our study revealed that the 5hmC level was substantially lower and 5mC level was slightly higher in gastric cancer tissues; however, 5-formylcytosine (5fC) and 5-carboxylcytosine (5caC) levels did not change significantly in these tissues. We further examined the expression levels of IDH1 and IDH2 in gastric cancer tissues and observed that IDH2 levels were significantly lower in gastric cancer tissues than in the adjacent normal tissues. The ectopic expression of IDH2 can increase 5hmC levels in gastric cancer cells. In conclusion, our results suggested that IDH2 dysfunction is involved in 5hmC depletion during gastric cancer progression. PMID:27466503

Patients who received public care for primary treatment, mostly surgical treatment, were compared with those who received private care in terms of demographics, mode of presentation, disease factors, comorbidity index and treatment factors. Cox regression modelling was performed with stepwise adjustments, and hazards of breast cancer specific mortality associated with the type of health care received was assessed. Results Of the 14,468 patients, 8,916 (61.6%) received public care. Compared to patients treated in private care facilities, they were older, more likely to be Māori, Pacifika or Asian and to reside in deprived neighbourhoods and rural areas, and less likely to be diagnosed with early staged cancer and to receive timely cancer treatments. They had a higher risk of mortality from breast cancer (hazard ratio: 1.95; 95% CI: 1.75, 2.17), of which 80% (95% CI: 63%, 100%) was explained by baseline differences, particularly related to ethnicity, stage at diagnosis and type of loco-regional therapy. After controlling for these demographic, disease and treatment factors, the risk of mortality was still 14% higher in the public sector patients. Conclusions Ethnicity, stage at diagnosis and type of loco-regional therapy were the three key contributors to survival disparities between patients treated in public and private health care facilities in New Zealand. The findings underscore the need for more efforts to improve the quality, timeliness and equitability of public cancer care services. PMID:27054698

  12. Spinal high-mobility group box 1 contributes to mechanical allodynia in a rat model of bone cancer pain

    International Nuclear Information System (INIS)

    Mechanisms underlying bone cancer-induced pain are largely unknown. Previous studies indicate that neuroinflammation in the spinal dorsal horn is especially involved. Being first reported as a nonhistone chromosomal protein, high-mobility group box 1 (HMGB1) is now implicated as a mediator of inflammation. We hypothesized that HMGB1 could trigger the release of cytokines in the spinal dorsal horn and contribute to bone cancer pain. To test this hypothesis, we first built a bone cancer pain model induced by intratibal injection of Walker 256 mammary gland carcinoma cells. The structural damage to the tibia was monitored by radiological analysis. The mechanical allodynia was measured and the expression of spinal HMGB1 and IL-1β was evaluated. We observed that inoculation of cancer cells, but not heat-killed cells, induced progressive bone destruction from 9 d to 21 d post inoculation. Behavioral tests demonstrated that the significant nociceptive response in the cancer cells-injected rats emerged on day 9 and this kind of mechanical allodynia lasted at least 21 d following inoculation. Tumor cells inoculation significantly increased HMGB1 expression in the spinal dorsal horn, while intrathecal injecting a neutralizing antibody against HMGB1 showed an effective and reliable anti-allodynia effect with a dose-dependent manner. IL-1β was significantly increased in caner pain rats while intrathecally administration of anti-HMGB1 could decrease IL-1β. Together with previous reports, we predict that bone cancer induces HMGB1 production, enhancing spinal IL-1β expression and thus modulating spinal excitatory synaptic transmission and pain response.

    Full Text Available The plasmacytoma variant translocation 1 gene (PVT1 is an lncRNA that has been designated as an oncogene due to its contribution to the phenotype of multiple cancers. Although the mechanism by which PVT1 influences disease processes has been studied in multiple cancer types, its role in cervical tumorigenesis remains unknown. Thus, the present study was designed to investigate the role of PVT1 in cervical cancer in vitro and in vivo. PVT1 expression was measured by quantitative PCR (qPCR in 121 invasive cervical carcinoma (ICC samples, 30 normal cervix samples, and cervical cell lines. Functional assays were carried out using both siRNA and LNA-mediated knockdown to examine PVT1's effects on cervical cancer cell proliferation, migration and invasion, apoptosis, and cisplatin resistance. Our results demonstrate that PVT1 expression is significantly increased in ICC tissue versus normal cervix and that higher expression of PVT1 correlates with poorer overall survival. In cervical cancer cell lines, PVT1 knockdown resulted in significantly decreased cell proliferation, migration and invasion, while apoptosis and cisplatin cytotoxicity were significantly increased in these cells. Finally, we show that PVT1 expression is augmented in response to hypoxia and immune response stimulation and that this lncRNA associates with the multifunctional and stress-responsive protein, Nucleolin. Collectively, our results provide strong evidence for an oncogenic role of PVT1 in cervical cancer and lend insight into potential mechanisms by which PVT1 overexpression helps drive cervical carcinogenesis.

    Reasons for the lodgment of metastases from several types of solid cancer at apparently non-random sites have not been established. Recently, a group of genes expressed in human fibroblasts obtained from different anatomic locations was implicated in "positional" genomic information. Essentially, a Cartesian coordinate system identifying fibroblasts originally resident at anterior or more posterior, proximal or distal and dermal or non-dermal (heart, lung, etc.) locations was proposed. The determinants used for these identifications included HOX genes, central to embryonic segmental development, some of which are expressed in differentiated, post-embryonic cells. To the extent that HOX or other homeobox genes are expressed in ectodermal, mesodermal or endodermally-derived, malignantly transformed cells, they might contribute "positional" information to nidation of specific malignant clones at non-random sites. As understood in the past, interdiction of HOX or homeobox-related gene expression might reduce the probability of cancer cell implantation or alter their destinations in complex ways. Ideally, by interfering with HOX or other homeobox gene-related expression of antigenic determinants potentially contributing to their "homing" and nidation, reduced implantation of circulating cancer cells could render them more susceptible to systemic chemotherapy or immunotherapy, as demonstrated in mice. Furthermore, HOX or other homeobox genes or their products could provide novel intra- or extracellular targets for therapy. PMID:17695497

    Full Text Available Background: The purposes of this study were to examine the impact of chemotherapy treatment on Jordanian cancer patients’ fatigue and to correlate their fatigue with selected sociodemographic variables at the beginning of treatment and after four weeks of treatment. Methods: This was a single group quasi-experimental correlational design study that enrolled 43 patients diagnosed with cancer who required chemotherapy treatment. Fatigue was measured according to the Piper Fatigue Scale (PFS before starting chemotherapy treatment and after four weeks of receiving the first dose of chemotherapy. Data were collected over a period of four weeks and analyzed with descriptive statistics, the paired-sample t-test, and Pearson product-moment correlation. Results: The study included 17 (39.5% males and 26 (60.5% females with a mean age of 45.98 years. Most (n=17 were diagnosed with breast cancer. Obesity was present in about 64.4% of patients. The majority (46% received an anthracycline-based regimen. There were statistically significant differences between respondents’ total mean scores of fatigue pre-treatment and four weeks following chemotherapy treatment (t= -2.31, df=42, P<0.05. In addition, significant differences were found in the scores for behavioral, affective, sensory, and cognitive dimensions subscales (t= -2.24, -2.19, - 2.4, -2.4, df=42, P<0.05 between pre-treatment and four weeks after receiving the first dose of chemotherapy treatment. We observed a significant negative relationship between fatigue scores and hemoglobin levels (r= -0.04, P<0.01. Conclusion: Cancer-related fatigue is common among cancer patients who received chemotherapy and result in substantial adverse physical, behavioral, cognitive and affective consequences for patient. Given the impact of fatigue, treatment options should be routinely considered in the care of patients with cancer.

    Full Text Available Abstract Background Three-dimensional (3D embedded cell cultures provide an appropriate physiological environment to reconstruct features of early glandular epithelial cancer. Although these are orders of magnitude simpler than tissues, they too are complex systems that have proven challenging to understand. We used agent-based, discrete event simulation modeling methods to build working hypotheses of mechanisms of epithelial 3D culture phenotype and early cancer progression. Starting with an earlier software analogue, we validated an improved in silico epithelial analogue (ISEA for cardinal features of a normally developed MDCK cyst. A set of axiomatic operating principles defined simulated cell actions. We explored selective disruption of individual simulated cell actions. New framework features enabled recording detailed measures of ISEA cell activities and morphology. Results Enabled by a small set of cell operating principles, ISEA cells multiplied and self-organized into cyst-like structures that mimicked those of MDCK cells in a 3D embedded cell culture. Selective disruption of "anoikis" or directional cell division caused the ISEA to develop phenotypic features resembling those of in vitro tumor reconstruction models and cancerous tissues in vivo. Disrupting either process, or both, altered cell activity patterns that resulted in morphologically similar outcomes. Increased disruption led to a prolonged presence of intraluminal cells. Conclusions ISEA mechanisms, behaviors, and morphological properties may have biological counterparts. To the extent that in silico-to-in vitro mappings are valid, the results suggest plausible, additional mechanisms of in vitro cancer reconstruction or reversion, and raise potentially significant implications for early cancer diagnosis based on histology. Further ISEA development and use are expected to provide a viable platform to complement in vitro methods for unraveling the mechanistic basis of

    BACKGROUND: Although there are many studies on the mechanism of chemoresistance in cancers, studies on the relations between WNT5A and chemoresistance in pancreatic cancer are rare. The present study was to examine the role of WNT5A in the regulation of cell cycle progression and in chemoresistance in pancreatic cancer tissues and cell lines. METHODS: Fresh pancreatic cancer and paracarcinoma tissues were obtained from 32 patients. The expressions of WNT5A, AKT/p-AKT and Cyclin D1 were detected by immunohistochemistry, and the correlation between WNT5A expression and clinicopathological characteristics was analyzed. The relationship between WNT5A expression and gemcitabine resistance was studied in PANC-1 and MIAPaCa2 cell lines. The effect of WNT5A on the regulation of cell cycle and gemcitabine cytotoxicity were investigated. The associations among the expressions of p-AKT, Cyclin D1 and WNT5A were also analyzed in cell lines and the effect of WNT5A on restriction-point (R-point) progression was evaluated. RESULTS: WNT5A, p-AKT and Cyclin D1 were highly expressed in pancreatic cancer tissues, and the WNT5A expression was correlated with the TNM stages. In vitro, WNT5A expression was associated with gemcitabine chemoresistance. The percentage of cells was increased in G0/G1 phase and decreased in S phase after knockdown of WNT5A in PANC-1. WNT5A promoted Cyclin D1 expression through phosphorylation of AKT which consequently enhanced G1-S transition and gemcitabine resistance. Furthermore, WNT5A enhanced the cell cycle progression toward R-point through regulation of retinoblastoma protein (pRb) and pRb-E2F complex formation. CONCLUSIONS: WNT5A induced chemoresistance by regulation of G1-S transition in pancreatic cancer cells. WNT5A might serve as a predictor of gemcitabine response and as a potential target for tumor chemotherapy.

    Background Axillary lymph node metastasis is a very important metastatic pathway in breast cancer and its accurate detection is important for staging tumour and guiding therapy. However, neither the accuracy of routine detection of lymph node in surgical specimens nor the significance of minute lymph node with metastases in breast cancer is clear. A modified method for conveniently detecting minute lymph node in specimens of axillary dissections in patients with breast cancer was used to analyze their influence on staging breast cancer.Methods Lymph nodes in fresh, unfixed, specimens of axillary dissections from 127 cases of breast cancer were detected routinely. Then the axillary fatty tissues were cut into 1 cm thick pieces, soaked in Carnoy's solution for 6 to 12 hours, taken out and put on a glass plate. Minute lymph nodes were detected by light of bottom lamp and examined by routine pathology.Results Lymph nodes (n= 2483, 19.6±8.0 per case) were found by routine method. A further 879 lymph nodes up to 6 mm (781 < 3 mm, 6.9±5.3 per case, increasing mean to 26.5±9.7) were found from the axillary tissues after soaking in Carnoy's solution. By detection of minute lymph nodes, the stages of lymph node metastasis in 7 cases were changed from pathological node (pN) stage pN0 to pN1 in 4 cases, from pN1 to pN2 in 2 and from pN2 to pN3 in 1.Conclusions The accurate staging of axillary lymph node metastasis can be obtained routinely with number of axillary lymph nodes in most cases of breast cancer. To avoid neglecting minute lymph nodes with metastases, small axillary nodes should be searched carefully in the cases of earlier breast cancer with no swollen axillary nodes. Treatment with Carnoy's solution can expediently detect minute axillary nodes and improve the accurate staging of lymph nodes in breast cancer.

    Lysine-specific demethylase-1 (LSD1) removes the methyl groups from mono- and di-methylated lysine 4 of histone H3. Previous studies have linked LSD1 to malignancy in several human tumors, and LSD1 is considered to epigenetically regulate the energy metabolism genes in adipocytes and hepatocellular carcinoma. This study investigates the function of LSD1 in the invasive activity and the metabolism of esophageal cancer cells. We investigated whether LSD1 immunohistochemical expression levels are related to clinical and pathological features, including the maximum standard uptake value in fluorodeoxyglucose positron emission tomography assay. The influence of LSD1 on cell proliferation, invasion and glucose uptake was evaluated in vitro by using specific small interfering RNA for LSD1, and an LSD1 inhibitor. We also evaluated two major energy pathways (glycolytic pathway and mitochondrial respiration) by measuring the extracellular acidification rate (ECAR) and the oxygen consumption rate (OCR) with an extracellular flux analyzer. High LSD1 immunohistochemical expression was significantly associated with high tumor stage, lymphovascular invasion, poor prognosis, and high maximum standard uptake value in esophageal cancer patients. In the in vitro analysis, LSD1 knockdown significantly suppressed the invasive activity and glucose uptake of cancerous cells, reduced their ECAR and increased their OCR and OCR/ECAR. LSD1 may contribute to malignant behavior by regulating the invasive activity and metabolism, activating the glycolytic pathway and inhibiting the mitochondrial respiration of esophageal cancer cells. The results support LSD1 as a potential therapeutic target. PMID:26240060

  1. Correction of electrode polarization contributions to the dielectric properties of normal and cancerous breast tissues at audio/radiofrequencies

    International Nuclear Information System (INIS)

    Spurious contributions from electrode polarization (EP) are a major nuisance in dielectric measurements of biological tissues and hamper accurate determination of tissue properties in the audio/radiofrequencies. Various electrode geometries and/or treatments have been employed traditionally to reduce EP contributions, although none succeeded to completely remove EP from measurements on tissues for all practical frequency ranges. A method of correction for contributions of EP to the dielectric properties of tissues is proposed. The method is based on modeling the electrode impedance with suitable functions and on the observation that certain parameters are only dependent on electrodes properties and can thus be determined separately. The method is tested on various samples with known properties, and its usefulness is demonstrated with samples of normal and cancerous human female breast tissue. It is observed that the dielectric properties of the tissues over the frequency range 40 Hz-100 MHz are significantly different among different types of breast tissue. This observation is used further to demonstrate that, by scanning the tip of the measuring dielectric probe (with modest spatial resolution) across a sample of excised breast tissue, significant variations in the electrical properties are detected at a position where a tumor is located. This study shows that dielectric spectroscopy has the potential to offer a viable alternative to the current methods for detection of breast cancer in vivo

    Background: Peutz-Jeghers syndrome (PJS) is characterized by intestinal polyposis, mucocutaneous pigmentation and an increased cancer risk, usually caused by mutations of the STK11 gene. This study collected epidemiological, clinical and genetic data from all Uruguayan PJS patients. Methods: Clinical data were obtained from public and private medical centers and updated annually. Sequencing of the STK11 gene in one member of each family was performed. Results and discussion: 25 cases in 11 unrelated families were registered (15 males, 10 females). The average age of diagnosis and death was 18 and 41 years respectively. All patients had characteristic PJS pigmentation and gastrointestinal polyps. 72% required urgent surgery due to intestinal obstruction. 3 families had multiple cases of seizure disorder, representing 20% of cases. 28% developed cancer and two patients had more than one cancer. An STK11 mutation was found in 8 of the 9 families analyzed. A unique M136K missense mutation was noted in one family. Comparing annual live births and PJS birth records from 1970 to 2009 yielded an incidence of 1 in 155,000. Conclusion: The Uruguayan Registry for Peutz-Jeghers patients showed a high chance of emergent surgery, epilepsy, cancer and shortened life expectancy. The M136K missense mutation is a newly reported STK 11 mutation. © 2013 Tchekmedyian et al.

    CUB and sushi multiple domain protein 1 (CSMD1) is a candidate tumor suppressor gene. The three members of CSMD family have very similar structures, each consisting of 14 CUB domains separated from one another by a sushi domain, an additional uninterrupted array of sushi domains, a single transmembrane domain, and a short cytoplasmic tail. In this work, we aimed to study the protein and mRNA levels of the CSMD1, CSMD2, and CSMD3 and evaluate their prognostic importance in colorectal cancer. Reduced expressions of these three proteins were detected in colorectal cancer tissues by comparing matched normal tissues. Low CSMD2 expression was significantly associated with differentiation, lymphatic invasion, and tumor size. CSMD3 was associated with differentiation and lymphatic invasion. CSMD1 and CSMD2 expressions were associated with overall survival. This study offers convincing evidence for the first time that the three genes of CSMD family were downregulated in the patients with colorectal cancer and may be used as predictors of colorectal cancer.

    A registry has been established to document certain characteristics on a sizeable worldwide sample of individuals with savant syndrome, a rare but remarkable condition in which persons with developmental disabilities, brain injury, or brain disease have some spectacular "islands" of skill or ability that stand in jarring, marked contrast to overall handicap. Of the 319 savants included in the registry, 90% are congenital savants, while 10% are acquired savants. The registry includes individuals from 33 countries, with 70% from the United States or Canada. Sex distribution was 79% male vs. 21% female (4:1). This report summarizes the findings in the congenital savant syndrome category of the registry. Among the individuals with congenital savant syndrome, the most common underlying disability was Autistic Spectrum Disorder (75%); various other central nervous system (CNS) disorders were present in the other 25%. Fifty-five percent possessed a single special skill, while 45% had multiple skills. Music was the most frequent principal skill followed by art, memory, mathematics, calendar calculating, language, visual-spatial/mechanical, athletic, computer, extrasensory perception, and other skills.

    Aim: Sulfotransferase-catalyzed sulfation is the most important pathway for inactivating estrogens. Thus, activation of estrogen sulfotransferase (EST) may be an alternative approach for the treatment of estrogen-dependent breast cancer. In this study we investigated the involvement of EST in anti-breast cancer effects of the dithiocarbamate derivative TM208 in vitro and in vivo. Methods: The viability of human breast cancer MCF-7 cells was determined using a SBB assay. Nude mice bearing MCF-7 cells were orally administered TM208 (50 and 150 mg·kg−1·d−1) for 18 days. The xenograft tumors and uteri were collected. The mRNA expression of EST was examined with real-time PCR. EST protein was detected with Western blot, ELISA or immunohistochemical staining assays. A radioactive assay was used to measure the EST activity. Uterotropic bioassay was used to examine the uterine estrogen responses. Results: Treatment with TM208 (10, 15 and 20 μmol/L) concentration-dependently increased EST expression in MCF-7 cells in vitro. Co-treatment with triclosan, an inhibitor of sulfonation, abolished TM208-induced cytotoxicity in MCF-7 cells. TM208 exhibited an apparent anti-estrogenic property: it exerted more potent cytotoxicity in E2-treated MCF-7 cells. In the nude mice bearing MCF-7 cells, TM208 administration time-dependently increased the expression and activity of EST, and blocked the gradual increase of E2 concentration in the xenograft tumors. Furthermore, TM208 administration blocked the estrogens-stimulated uterine enlargement. Tamoxifen, a positive control drug, produced similar effects on the expression and activity of EST in vitro and in vivo. Conclusion: The induction of EST and reduction of estrogen concentration contribute to the anti-breast cancer action of TM208 and tamoxifen. TM208 may be developed as anticancer drug for the treatment of estrogen receptor-positive breast cancer. PMID:25937633

    Full Text Available Abstract Background Both obesity and type 2 diabetes are among the risk factors for breast cancer development. Combined effect of these metabolic abnormalities on breast cancer risk however, has not been examined in premenopausal women. We tested this association in type 2 diabetic women, categorized as obese, overweight and normal body weight groups based on BMI. Design and methods A total of 101 subjects were included in this study. Serum levels of IL-6, TNF-α, C reactive protein, leptin, TGF-α, adiponectin and insulin were measured by ELISA. Data were logarithmically transformed for variables not normally distributed. Analysis of variance with post-hoc Bonferroni was applied to compare the data between the groups. Simple and partial correlation coefficients between the variables were determined and a stepwise multiple linear regression analysis was performed to determine the relationships between the variables of interest. Results Significantly increased levels of IL-6, C reactive protein, leptin and significantly decreased levels of adiponectin were found in obese group, while the levels of TNF-α and TGF-α were unaltered. A positive correlation between waist circumference and IL-6 was found in obese group. Similarly, C reactive protein, waist and hip circumferences were linearly correlated with BMI in obese group. Stepwise multiple linear regression analysis revealed several significant predictors for breast cancer risk. Conclusion Obesity and type 2 diabetes, owing to their effects on adipocytokines and inflammatory mediators, contribute to increased breast cancer risk in premenopausal women. This study emphasizes healthy life style and better management of these metabolic disorders to avoid the pathogenesis of breast cancer and of other chronic diseases.

  15. Second primary cancers in survivors of cervical cancer in the Netherlands: Implications for prevention and surveillance

    International Nuclear Information System (INIS)

    Background and purpose: We investigated the effects of socio-demographic, treatment- and tumor-specific determinants on the risk of developing a second malignancy among patients treated for cervical cancer. Material and methods: We included patients with a first cervical cancer (N = 12,048) from the Netherlands Cancer Registry (NCR), 1989–2008. Standardized incidence ratios (SIR) and absolute excess risks (AER) per 10,000 person-years were calculated to estimate the burden of second cancers in cervical cancer survivors. Incidence rate ratios (IRR) were computed to identify predictors for second cancers among cervical cancer survivors. Results: During the study period, 676 (5.6%) patients were diagnosed with a second cancer. Smoking-related cancers contributed the most to the overall burden of second cancers (AER = 21) and risks remained elevated after 10 years of follow-up (SIR = 1.8, 95% CI: 1.4–2.2), yet it decreased markedly in the younger birth cohorts. Cervical cancer survivors who underwent radiotherapy were at higher risk for a second tumor when compared to those without radiotherapy, especially at smoking-related sites (IRR = 1.6 (1.2–2.3)). Conclusion: Patients with cervical cancer had a significantly increased risk for a second cancer compared to the general population, especially for smoking- and irradiation-related tumors. Long-term follow-up suggested the importance of smoking cessation and the benefits of counseling cervical cancer patients accordingly, particularly those who received radiotherapy

    Summary Imaging studies in animals and in humans have indicated that the oxygenation and nutritional status of solid tumors is dynamic. Further, the extremely low level of glucose within tumors, while reflecting its rapid uptake and metabolism, also suggests that cancer cells must rely on other energy sources in some circumstances. Here we find that some breast cancer cells can switch to utilizing lactate as a primary source of energy, allowing them to survive glucose deprivation for extended periods, and that this activity confers resistance to PI3K/mTOR inhibitors. The nuclear receptor, estrogen-related receptor alpha (ERRα), was shown to regulate the expression of genes required for lactate utilization and isotopomer analysis revealed that genetic or pharmacological inhibition of ERRα activity compromised lactate oxidation. Importantly, ERRα antagonists increased the in vitro and in vivo efficacy of PI3K/mTOR inhibitors, highlighting the potential clinical utility of this drug combination. PMID:27050525

  17. Genetic background may contribute to PAM50 gene expression breast cancer subtype assignments.

    Directory of Open Access Journals (Sweden)

    Ying Hu

    Full Text Available Recent advances in genome wide transcriptional analysis have provided greater insights into the etiology and heterogeneity of breast cancer. Molecular signatures have been developed that stratify the conventional estrogen receptor positive or negative categories into subtypes that are associated with differing clinical outcomes. It is thought that the expression patterns of the molecular subtypes primarily reflect cell-of-origin or tumor driver mutations. In this study however, using a genetically engineered mouse mammary tumor model we demonstrate that the PAM50 subtype signature of tumors driven by a common oncogenic event can be significantly influenced by the genetic background on which the tumor arises. These results have important implications for interpretation of "snapshot" expression profiles, as well as suggesting that incorporation of genetic background effects may allow investigation into phenotypes not initially anticipated in individual mouse models of cancer.

  18. Contributions of the Epidermal Growth Factor Receptor to Acquisition of Platinum Resistance in Ovarian Cancer Cells

    Acquisition of platinum resistance following first line platinum/taxane therapy is commonly observed in ovarian cancer patients and prevents clinical effectiveness. There are few options to prevent platinum resistance; however, demethylating agents have been shown to resensitize patients to platinum therapy thereby demonstrating that DNA methylation is a critical contributor to the development of platinum resistance. We previously reported the Epidermal Growth Factor Receptor (EGFR) is a nove...

    T-regulatory cells (Treg) and mast cells (MC) are abundant in colorectal cancer (CRC) tumors. Interaction between the two is known to promote immune suppression or loss of Treg functions and autoimmunity. Here, we demonstrate that in both human CRC and murine polyposis the outcome of this interaction is the generation of potently immune suppressive but proinflammatory Treg (ΔTreg). These Treg shut down IL10, gain potential to express IL17, and switch from suppressing to promoting MC expansion...

    Full Text Available Background/Aims: Early parity reduces breast cancer risk, whereas, late parity and nulliparity increase breast cancer risk. Despite substantial efforts to understand the protective effects of early parity, the precise molecular circuitry responsible for these changes is not yet fully defined. Methods: Here, we have conducted the first study assessing protein expression profiles in normal breast tissue of healthy early parous, late parous, and nulliparous women. Breast tissue biopsies were obtained from 132 healthy parous and nulliparous volunteers. These samples were subjected to global protein expression profiling and immunohistochemistry. GeneSpring and MetaCore bioinformatics analysis software were used to identify protein expression profiles associated with early parity (low risk versus late/nulliparity (high risk. Results: Early parity reduces expression of key proteins involved in mitogenic signaling pathways in breast tissue through down regulation of EGFR1/3, ESR1, AKT1, ATF, Fos, and SRC. Early parity is also characterized by greater genomic stability and reduced tissue inflammation based on differential expression of aurora kinases, p53, RAD52, BRCA1, MAPKAPK-2, ATF-1, ICAM1, and NF-kappaB compared to late and nulli parity. Conclusions: Early parity reduces basal cell proliferation in breast tissue, which translates to enhanced genomic stability, reduced cellular stress/inflammation, and thus reduced breast cancer risk.

    Full-length (FL) docking protein-1 (DOK1) is an adapter protein which inhibits growth factor and immune response pathways in normal tissues, but is frequently lost in human cancers. Small DOK1 variants remain in cells of solid tumors and leukemias, albeit, their functions are elusive. To assess the so far unknown role of DOK1 in colorectal cancer (CRC), we generated DOK1 mutants which mimic the domain structure and subcellular distribution of DOK1 protein variants in leukemia patients. We found that cytoplasmic DOK1 activated peroxisome-proliferator-activated-receptor-gamma (PPARγ) resulting in inhibition of the c-FOS promoter and cell proliferation, whereas nuclear DOK1 was inactive. PPARγ-agonist increased expression of endogenous DOK1 and interaction with PPARγ. Forward translation of this cell-based signaling model predicted compartmentalization of DOK1 in patients. In a large series of CRC patients, loss of DOK1 protein was associated with poor prognosis at early tumor stages (*p=0.001; n=1492). In tumors with cytoplasmic expression of DOK1, survival was improved, whereas nuclear localization of DOK1 correlated with poor outcome, indicating that compartmentalization of DOK1 is critical for CRC progression. Thus, DOK1 was identified as a prognostic factor for non-metastatic CRC, and, via its drugability by PPARγ-agonist, may constitute a potential target for future cancer treatments. PMID:27428427

  3. Risk of lung cancer from radon exposure: contribution of recently published studies of uranium miners

    International Nuclear Information System (INIS)

    The International Commission on Radiological Protection (ICRP) recently estimated the risk of lung cancer associated with radon exposure, and a statement was issued in ICRP Publication 115. This was based on recent epidemiological studies and the results from a joint analysis of cohorts of Czech, French, and German uranium miners, and indicated that the excess relative risk of lung cancer per unit of exposure should be expressed with consideration of chronic exposure over more than 10 years, by modelling time since median exposure, age attained or age at exposure, and taking in account, if possible, interaction between radon and tobacco. The lifetime excess absolute risk (LEAR) calculated from occupational exposure studies is close to 5 × 10−4 per working level month (WLM) (14 × 10−5 per hm J/m3). LEAR values estimated using risk models derived from both miners and domestic exposure studies are in good agreement after accounting for factors such as sex, attained age, and exposure scenario. A sensitivity analysis highlighted the high dependence of background mortality rates on LEAR estimates. Using lung cancer rates among Euro-American males instead of the ICRP reference rates (males and females, and Euro-American and Asian populations), the estimated LEAR is close to 7 × 10−4 per WLM (20 × 10−5 per hm J/m3).

    The present study aimed to investigate the molecular mechanisms underlying non-syndromic cleft lip, with or without cleft palate (NSCL/P), and the association between this disease and cancer. The GSE42589 data set was downloaded from the Gene Expression Omnibus database, and contained seven dental pulp stem cell samples from children with NSCL/P in the exfoliation period, and six controls. Differentially expressed genes (DEGs) were screened using the RankProd method, and their potential functions were revealed by pathway enrichment analysis and construction of a pathway interaction network. Subsequently, cancer genes were obtained from six cancer databases, and the cancer-associated protein-protein interaction network for the DEGs was visualized using Cytoscape. In total, 452 upregulated and 1,288 downregulated DEGs were screened. The upregulated DEGs were significantly enriched in the arachidonic acid metabolism pathway, including PTGDS, CYP4F2 and PLA2G16; and transforming growth factor (TGF)-β signaling pathway, including SMAD3 and TGFB2. The downregulated DEGs were distinctly involved in the pathways of DNA replication, including MCM2 and POLA1; cell cycle, including CDK1 and STAG1; and viral carcinogenesis, including PIK3CA and HIST1H2BF. Furthermore, the pathways of cell cycle and viral carcinogenesis, with higher degrees of interaction were found to interact with other pathways, including DNA replication, transcriptional misregulation in cancer, and the TGF-β signaling pathway. Additionally, TP53, CDK1, SMAD3, PIK3R1 and CASP3, with higher degrees, interacted with the cancer genes. In conclusion, the DEGs for NSCL/P were implicated predominantly in the TGF-β signaling pathway, the cell cycle and in viral carcinogenesis. The TP53, CDK1, SMAD3, PIK3R1 and CASP3 genes were found to be associated, not only with NSCL/P, but also with cancer. These results may contribute to a better understanding of the molecular mechanisms of NSCL/P. PMID:26795696

  5. Towards a national trauma registry for the United Arab Emirates

    2010-07-01

    Full Text Available Abstract Background Trauma is a major health problem in the United Arab Emirates (UAE as well as worldwide. Trauma registries provide large longitudinal databases for analysis and policy improvement. We aim in this paper to report on the development and evolution of a national trauma registry using a staged approach by developing a single-center registry, a two-center registry, and then a multi-center registry. The three registries were established by developing suitable data collection forms, databases, and interfaces to these databases. The first two registries collected data for a finite period of time and the third is underway. The steps taken to establish these registries depend on whether the registry is intended as a single-center or multi-center registry. Findings Several issues arose and were resolved during the development of these registries such as the relational design of the database, whether to use a standalone database management system or a web-based system, and the usability and security of the system. The inclusion of preventive medicine data elements is important in a trauma registry and the focus on road traffic collision data elements is essential in a country such as the UAE. The first two registries provided valuable data which has been analyzed and published. Conclusions The main factors leading to the successful establishment of a multi-center trauma registry are the development of a concise data entry form, development of a user-friendly secure web-based database system, the availability of a computer and Internet connection in each data collection center, funded data entry personnel well trained in extracting medical data from the medical record and entering it into the computer, and experienced personnel in trauma injuries and data analysis to continuously maintain and analyze the registry.

  6. Survival discriminants for differentiated thyroid cancer

    International Nuclear Information System (INIS)

    Since 1975, the American Cancer Society, Illinois Division, has published end results of major cancer sites drawn from patient data contributed voluntarily by hospital cancer registries throughout the state. The current study was undertaken, in part, to apprehend information regarding contested areas in the management of patients having differentiated (papillary/follicular) thyroid cancer. A total of 2,282 patients with either papillary or follicular carcinoma of the thyroid from 76 different Illinois hospitals and providing 10 years of follow-up information (life-table analysis) were retrospectively analyzed for demographic, disease, and treatment-related predictors of survival. Multivariate analysis using the Cox proportional hazards method was made for stage, age, race, sex, morphology, history of radiation exposure, presence of positive lymph nodes, initial surgical treatment, postoperative iodine 131 therapy, and replacement/suppressive thyroid hormone treatment. Statistically significant (p less than or equal to 0.05) predictors of favorable survival after thyroid cancer were low stage (I and II), young age (less than 50 years), white race, female sex, and the administration, postoperatively, of either thyroid hormone or radioactive iodine. Factors that had no influence on survival were lymph node status, choice of initial surgical treatment, and a history of prior irradiation. We suggest that where a prospective clinical trial is impracticable, a retrospective analysis of a large and detailed database, such as that available from cooperating hospital-based tumor registries, may yet provide useful insights to solutions of cancer management problems

Black-Right-Pointing-Pointer Reversal of altered gene expression can enhance the anti-cancer effects of butyrate. -- Abstract: Butyrate, a fermentation product of dietary fiber, inhibits clonal growth in colorectal cancer (CRC) cells dependent upon the fold induction of Wnt activity. We have developed a CRC cell line (HCT-R) that, unlike its parental cell line, HCT-116, does not respond to butyrate exposure with hyperactivation of Wnt signaling and suppressed clonal growth. PCR array analyses revealed Wnt pathway-related genes, the expression of which differs between butyrate-sensitive HCT-116 CRC cells and their butyrate-resistant HCT-R cell counterparts. We identified overexpression of Tcf3 as being partially responsible for the butyrate-resistant phenotype, as this DNA-binding protein suppresses the hyperinduction of Wnt activity by butyrate. Consequently, Tcf3 knockdown in HCT-R cells restores their sensitivity to the effects of butyrate on Wnt activity and clonal cell growth. Interestingly, the effects of overexpressed Tcf3 differ between HCT-116 and HCT-R cells; thus, in HCT-116 cells Tcf3 suppresses proliferation without rendering the cells resistant to butyrate. In HCT-R cells, however, the overexpression of Tcf3 inhibits Wnt activity, and the cells are still able to proliferate due to the higher expression levels of cell cycle factors, particularly those driving the G{sub 1} to S transition. Knowledge of the molecular mechanisms determining the variable sensitivity of CRC cells to butyrate may assist in developing approaches that

  9. CD133+ cells contribute to radioresistance via altered regulation of DNA repair genes in human lung cancer cells

    International Nuclear Information System (INIS)

    Background: Radioresistance in human tumors has been linked in part to a subset of cells termed cancer stem cells (CSCs). The prominin 1 (CD133) cell surface protein is proposed to be a marker enriching for CSCs. We explore the importance of DNA repair in contributing to radioresistance in CD133+ lung cancer cells. Materials and methods: A549 and H1299 lung cancer cell lines were used. Sorted CD133+ cells were exposed to either single 4 Gy or 8 Gy doses and clonogenic survival measured. ϒ-H2AX immunofluorescence and quantitative real time PCR was performed on sorted CD133+ cells both in the absence of IR and after two single 4 Gy doses. Lentiviral shRNA was used to silence repair genes. Results: A549 but not H1299 cells expand their CD133+ population after single 4 Gy exposure, and isolated A549 CD133+ cells demonstrate IR resistance. This resistance corresponded with enhanced repair of DNA double strand breaks (DSBs) and upregulated expression of DSB repair genes in A549 cells. Prior IR exposure of two single 4 Gy doses resulted in acquired DNA repair upregulation and improved repair proficiency in both A549 and H1299. Finally Exo1 and Rad51 silencing in A549 cells abrogated the CD133+ IR expansion phenotype and induced IR sensitivity in sorted CD133+ cells. Conclusions: CD133 identifies a population of cells within specific tumor types containing altered expression of DNA repair genes that are inducible upon exposure to chemotherapy. This altered gene expression contributes to enhanced DSB resolution and the radioresistance phenotype of these cells. We also identify DNA repair genes which may serve as promising therapeutic targets to confer radiosensitivity to CSCs

  10. Where the Semantic Web and Web 2.0 Meet Format Risk Management: P2 Registry

    Full Text Available The Web is increasingly becoming a platform for linked data. This means making connections and adding value to data on the Web. As more data becomes openly available and more people are able to use the data, it becomes more powerful. An example is file format registries and the evaluation of format risks. Here the requirement for information is now greater than the effort that any single institution can put into gathering and collating this information. Recognising that more is better, the creators of PRONOM, JHOVE, GDFR and others are joining to lead a new initiative: the Unified Digital Format Registry. Ahead of this effort, a new RDF-based framework for structuring and facilitating file format data from multiple sources, including PRONOM, has demonstrated it is able to produce more links, and thus provide more answers to digital preservation questions - about format risks, applications, viewers and transformations - than the native data alone. This paper will describe this registry, P2, and its services, show how it can be used, and provide examples where it delivers more answers than the contributing resources. The P2 Registry is a reference platform to allow and encourage publication of preservation data, and also an examplar of what can be achieved if more data is published openly online as simple machine-readable documents. This approach calls for the active participation of the digital preservation community to contribute data by simply publishing it openly on the Web as linked data.

    2016-01-01

    Colorectal cancer (CRC) is a major health problem in Asia. It has been reported that the Chinese are more susceptible to CRC than many other ethnic groups. Screening for CRC is a cost-effective prevention and control strategy; however, the screening rates among the Chinese are sub-optimal. We conducted a review to identify the factors associated with CRC screening participation among Chinese people. Twenty-two studies that examined the factors related to CRC screening behaviors among the Chinese were identified through five databases. Seven factors were consistently reported to influence CRC screening behaviors in at least one of the studies: socio-demographic characteristics (educational level, health insurance, and knowledge about CRC and its screening); psychological factors (perceived severity of CRC, susceptibility of having CRC, and barriers to screening); and contact with medical provider (physician recommendation). The evidence base for many of these relationships is quite limited. Furthermore, the associations of many factors, including age, gender, income, cancer worry/fear, and self-efficacy with CRC screening behaviors, were mixed or inconsistent across these studies, thereby indicating that more studies are needed in this area.

    The mechanism of neuroendocrine transdifferentiation (NED) during the development of castration-resistant prostate cancer (CRPC) remains undefined. Although androgen-deprivation therapy (ADT) can impair tumor cell growth, ADT can also triggers a parallel reaction, leading to increased neurotensin (NTS) production in cancer associated stromal cells which drives NED. Here, we systematically explore the NTS network in tumor microenvironment that drives NED following ADT. The CK8+/CK14+ intermediate cells, as opposed to other epithelial cells, can be transdifferentiated to neuroendocrine (NE) status by excessive NTS through simultaneous activation of neurotensin receptor 1 (NTSR1)-PRKACB and 3 (NTSR3)-AHNAK axes. The importance of PRKACB and AHNAK in NED development was then confirmed in human prostate tumor tissues. More importantly, we demonstrated SR48692 (an inhibitor of NTSR1) could inhibit NED and prevent castration resistance in prostate tumor from xenografts and TRAMP models. We propose that targeting this pathway could provide benefit for patients with tumors expressing high levels of NTS following ADT.

  15. A contribution to improved radiotherapy for muscle invading urinary bladder cancer

    International Nuclear Information System (INIS)

    Cystectomy has traditionally been regarded the treatment of choice for muscle invading urinary bladder cancer in most countries. Radiotherapy has been offered patients considered unfit for cystectomy. Since the contraindications of surgery are frequent among bladder cancer patients, a substantial amount of patients with muscle invading bladder cancer (typically 50%) are still managed primarily with radiation. Recently, a tri-modality, organsparing treatment (trans-urethral resection and radio-chemotherapy) has been proposed for bladder cancer, like in the management of a range of other common malignancies. This approach may provide as high control rates as cystectomy yet maintain a higher quality of life for selected patient groups. In both the radical radiotherapy and the combined modality approach, high radiation doses are needed to improve local disease control. Radiation dose escalation requires improved conformation of dose distributions. This PhD programme aimed to develop improved conformal radiotherapy procedures in the management of patients with muscle invading urinary bladder cancer. In the initial phase of this work, computer-controlled movement of the linear accelerator collimator jaws during beam delivery was applied to shape so-called partially wedged beams (PWBs), that were designed specifically to tailor the dose distribution in bladder irradiation closer to the defined bladder target. The dosimetric verification and treatment planning implementation of this beam delivery concept were addressed, and we documented that these dynamic beams were delivered as accurately as standard beams. Particular attention was given to the BMS-96 diode array system, as it was adapted to dynamic beam dosimetry. Next, the potential clinical impact of these beams was analysed. In a retrospectively study of a set of urinary bladder treatment plans, the PWBs were seen to improve the dose homogeneity inside the bladder target as well as to reduce normal tissue (small

In both the radical radiotherapy and the combined modality approach, high radiation doses are needed to improve local disease control. Radiation dose escalation requires improved conformation of dose distributions. This PhD programme aimed to develop improved conformal radiotherapy procedures in the management of patients with muscle invading urinary bladder cancer. In the initial phase of this work, computer-controlled movement of the linear accelerator collimator jaws during beam delivery was applied to shape so-called partially wedged beams (PWBs), that were designed specifically to tailor the dose distribution in bladder irradiation closer to the defined bladder target. The dosimetric verification and treatment planning implementation of this beam delivery concept were addressed, and we documented that these dynamic beams were delivered as accurately as standard beams. Particular attention was given to the BMS-96 diode array system, as it was adapted to dynamic beam dosimetry. Next, the potential clinical impact of these beams was analysed. In a retrospectively study of a set of urinary bladder treatment plans, the PWBs were seen to improve the dose homogeneity inside the bladder target as well as to reduce normal tissue (small

    Activities of the Nova Scotia Registry of Mineral and Petroleum Titles are described, including statistical information about staking and mining activity in the province during 1999. In terms of activities, the Registry receives applications and issues licenses and leases for mineral and petroleum rights, receives statements of exploration expenditures and assessment reports that pertain to renewal of licenses and leases, maintains maps showing the disposition of lands under license or lease, and maintains a system of prospector registration. In addition, the Registry processes applications for underground gas storage rights and treasure trove rights and maintains a database of information concerning production and employment in Nova Scotia mines and quarries. At the end 1999 there were 230,660 hectares under exploration licence. Exploration expenditures, including engineering, economic and feasibility studies during 1999 totalled $4.2 million, mostly by junior mining companies searching for industrial mineral commodities. Mining activity during 1999 generated revenues of $340 million. Coal production dropped by 25 per cent, due mainly to the closure of the Phalen Mine. Gypsum production was up to 7.9 million tonnes; shipments of cement, barite and clay products also increased during 1999; salt production remained unchanged from 1998 with 842,000 tonnes. Production of construction aggregates totalled 10.6 million tonnes, down slightly from the year before. Mineral industry employment was roughly 2,500 persons, down by 24 per cent from 1998 levels, due primarily to the closure of the Phalen Mine.

    High-throughput molecular profiling approaches have emerged as precious research tools in the field of head and neck translational oncology. Such approaches have identified and/or confirmed the role of several genes or pathways in the acquisition/maintenance of an invasive phenotype and the execution of cellular programs related to cell invasion. Recently published new-generation sequencing studies in head and neck squamous cell carcinoma (HNSCC) have unveiled prominent roles in carcinogenesis and cell invasion of mutations involving NOTCH1 and PI3K-patwhay components. Gene-expression profiling studies combined with systems biology approaches have allowed identifying and gaining further mechanistic understanding into pathways commonly enriched in invasive HNSCC. These pathways include antigen-presenting and leucocyte adhesion molecules, as well as genes involved in cell-extracellular matrix interactions. Here we review the major insights into invasiveness in head and neck cancer provided by high-throughput molecular profiling approaches.

  2. Contribution of customised dosimetry for small animal to the treatments of cancers by metabolic radiotherapy

    International Nuclear Information System (INIS)

    This research thesis first reports a bibliographical study which addressed the use of ionizing radiations in cancer therapy (evolution from ionizing radiation to metabolic radiotherapy, biological and physical parameters, and absorbed dose in metabolic radiotherapy) and the role imagery has in customised dosimetry (absorbed dose calculation methods, determination of cumulative activity, dosimetric models for S factor calculation). Then, the author presents a software which has been specifically developed for the creation of dosimetric models, and reports its validation. He reports the comparison between different dosimetric models in the case of mice. He highlights two applications of the developed tool: radio-immunotherapy and metabolic radiotherapy. He finally proposes a general discussion on the impact of small animal dosimetry on metabolic radiotherapy

  3. Contribution of radioisotopic techniques to identify sentinel lymph-nodes (SLN) in breast cancer

    International Nuclear Information System (INIS)

    The SLN (one or several) is the first to receive lymph from a tumor. When a cancer cell comes off the tumor and circulates along the outgoing lymph, it meets a barrier, the SLN that intercepts and destroys it. If not, the cancer cell can stay and reproduce in the SLN making a metastasis which can affect other nodes in the same way. It has been shown that if the original tumor is small there is little chance that the SLN could be invaded and therefore little chance of dissemination to other lymph-nodes. Nowadays due to early detection, breast tumors are smaller than one cm, therefore with such size there is little chance of axillary lymph-nodes being affected. If it is confirmed by histological study that the SLN is free of metastasis, it is not necessary to perform a axillary emptying. This identification of SLNs has been achieved because of the advances of Radioisotopic Techniques, which has been carried out in our Hospital since 1997. We have been adapting this technique to the national supply of equipment and radio compounds always under a reliable and secure way. The aim of this presentation is to highlight the radioisotopic identification of SLNs in clinical investigation in 'Angel H. Roffo Institute', and its daily practice compare with Positron Emission Tomography (PET). By combining Radioisotopic Lymphography, Lymphochromography and intra surgical detection of the SN with Gamma Probe, we have obtained a true negative value of 95% of the SN, with 5% false negative. Due to this method we have included SN study in daily practice breast tumor patients with tumor up to 5 cm of diameter. Comparing this methods result (5% false negative), with the PET results, using 18F-FDG, that has 33% false negatives, we conclude that a negative result can not replace this method of SN detection.

    Full Text Available Abstract Background The epithelial to mesenchymal transition (EMT is a molecular process through which an epithelial cell undergoes transdifferentiation into a mesenchymal phenotype. The role of EMT in embryogenesis is well-characterized and increasing evidence suggests that elements of the transition may be important in other processes, including metastasis and drug resistance in various different cancers. Methods Agilent 4 × 44 K whole human genome arrays and selected reaction monitoring mass spectrometry were used to investigate mRNA and protein expression in A2780 cisplatin sensitive and resistant cell lines. Invasion and migration were assessed using Boyden chamber assays. Gene knockdown of snail and slug was done using targeted siRNA. Clinical relevance of the EMT pathway was assessed in a cohort of primary ovarian tumours using data from Affymetrix GeneChip Human Genome U133 plus 2.0 arrays. Results Morphological and phenotypic hallmarks of EMT were identified in the chemoresistant cells. Subsequent gene expression profiling revealed upregulation of EMT-related transcription factors including snail, slug, twist2 and zeb2. Proteomic analysis demonstrated up regulation of Snail and Slug as well as the mesenchymal marker Vimentin, and down regulation of E-cadherin, an epithelial marker. By reducing expression of snail and slug, the mesenchymal phenotype was largely reversed and cells were resensitized to cisplatin. Finally, gene expression data from primary tumours mirrored the finding that an EMT-like pathway is activated in resistant tumours relative to sensitive tumours, suggesting that the involvement of this transition may not be limited to in vitro drug effects. Conclusions This work strongly suggests that genes associated with EMT may play a significant role in cisplatin resistance in ovarian cancer, therefore potentially leading to the development of predictive biomarkers of drug response or novel therapeutic strategies for

  5. The use of breast conserving surgery: linking insurance claims with tumor registry data

    International Nuclear Information System (INIS)

    The purpose of this study was to use insurance claims and tumor registry data to examine determinants of breast conserving surgery (BCS) in women with early stage breast cancer. Breast cancer cases registered in the Hawaii Tumor Registry (HTR) from 1995 to 1998 were linked with insurance claims from a local health plan. We identified 722 breast cancer cases with stage I and II disease. Surgical treatment patterns and comorbidities were identified using diagnostic and procedural codes in the claims data. The HTR database provided information on demographics and disease characteristics. We used logistic regression to assess determinants of BCS vs. mastectomy. The linked data set represented 32.8% of all early stage breast cancer cases recorded in the HTR during the study period. Due to the nature of the health plan, 79% of the cases were younger than 65 years. Women with early stage breast cancer living on Oahu were 70% more likely to receive BCS than women living on the outer islands. In the univariate analysis, older age at diagnosis, lower tumor stage, smaller tumor size, and well-differentiated tumor grade were related to receiving BCS. Ethnicity, comorbidity count, menopausal and marital status were not associated with treatment type. In addition to developing solutions that facilitate access to radiation facilities for breast cancer patients residing in remote locations, future qualitative research may help to elucidate how women and oncologists choose between BCS and mastectomy

  6. Shear-wave elastography contributes to accurate tumour size estimation when assessing small breast cancers

    International Nuclear Information System (INIS)

    Aim: To assess whether the size of peritumoural stiffness (PTS) on shear-wave elastography (SWE) for small primary breast cancers (≤15 mm) was associated with size discrepancies between grey-scale ultrasound (GSUS) and final histological size and whether the addition of PTS size to GSUS size might result in more accurate tumour size estimation when compared to final histological size. Materials and methods: A retrospective analysis of 86 consecutive patients between August 2011 and February 2013 who underwent breast-conserving surgery for tumours of size ≤15 mm at ultrasound was carried out. The size of PTS stiffness was compared to mean GSUS size, mean histological size, and the extent of size discrepancy between GSUS and histology. PTS size and GSUS were combined and compared to the final histological size. Results: PTS of >3 mm was associated with a larger mean final histological size (16 versus 11.3 mm, p < 0.001). PTS size of >3 mm was associated with a higher frequency of underestimation of final histological size by GSUS of >5 mm (63% versus 18%, p < 0.001). The combination of PTS and GSUS size led to accurate estimation of the final histological size (p = 0.03). The size of PTS was not associated with margin involvement (p = 0.27). Conclusion: PTS extending beyond 3 mm from the grey-scale abnormality is significantly associated with underestimation of tumour size of >5 mm for small invasive breast cancers. Taking into account the size of PTS also led to accurate estimation of the final histological size. Further studies are required to assess the relationship of the extent of SWE stiffness and margin status. - Highlights: • Peritumoural stiffness of greater than 3 mm was associated with larger tumour size. • Underestimation of tumour size by ultrasound was associated with peri-tumoural stiffness size. • Combining peri-tumoural stiffness size to ultrasound produced accurate tumour size estimation

    Head and neck squamous cell carcinomas (HNSCC) are the sixth most common malignancy globally, and an increasing proportion of oropharyngeal HNSCCs are associated with the human papillomavirus (HPV). Patients with HPV-associated tumours have markedly improved overall and disease-specific survival compared with their HPV-negative counterparts when treated with chemoradiation. Although the difference in outcomes between these two groups is clearly established, the mechanism underlying these differences remains an area of investigation. Data from preclinical, clinical and genomics studies have started to suggest that an increase in radio-sensitivity of HPV-positive HNSCC may be responsible for improved outcomes, the putative mechanisms of which we will review here. The Cancer Genome Atlas and others have recently documented a multitude of molecular differences between HPV-positive and HPV-negative tumours. Preclinical investigations by multiple groups have explored possible mechanisms of increased sensitivity to therapy, including examining differences in DNA repair, hypoxia and the immune response. In addition to differences in the response to therapy, some groups have started to investigate phenotypic differences between the two diseases, such as tumour invasiveness. Finally, we will conclude with a brief review of ongoing clinical trials that are attempting to de-escalate treatment to minimise long-term toxicity while maintaining cure rates. New insights from preclinical and genomic studies may eventually lead to personalised treatment paradigms for HPV-positive patients. PMID:27052795

    T-regulatory cells (Treg) and mast cells (MC) are abundant in colorectal cancer (CRC) tumors. Interaction between the two is known to promote immune suppression or loss of Treg functions and autoimmunity. Here, we demonstrate that in both human CRC and murine polyposis the outcome of this interaction is the generation of potently immune suppressive but proinflammatory Treg (DeltaTreg). These Treg shut down IL10, gain potential to express IL17, and switch from suppressing to promoting MC expansion and degranulation. This change is also brought about by direct coculture of MC and Treg, or culture of Treg in medium containing IL6 and IL2. IL6 deficiency in the bone marrow of mice susceptible to polyposis eliminated IL17 production by the polyp infiltrating Treg, but did not significantly affect the growth of polyps or the generation of proinflammatory Treg. IL6-deficient MC could generate proinflammatory Treg. Thus, MC induce Treg to switch function and escalate inflammation in CRC without losing T-cell-suppressive properties. IL6 and IL17 are not needed in this process. PMID:20308560

    Since its discovery in mice and humans 19 years ago, the contribution of alternatively spliced Stat3, Stat3β, to the overall functions of Stat3 has been controversial. Tyrosine-phosphorylated (p) Stat3β homodimers are more stable, bind DNA more avidly, are less susceptible to dephosphorylation, and exhibit distinct intracellular dynamics, most notably markedly prolonged nuclear retention, compared to pStat3α homodimers. Overexpression of one or the other isoform in cell lines demonstrated that Stat3β acted as a dominant-negative of Stat3α in transformation assays; however, studies with mouse strains deficient in one or the other isoform indicated distinct contributions of Stat3 isoforms to inflammation. Current immunological reagents cannot differentiate Stat3β proteins derived from alternative splicing vs. proteolytic cleavage of Stat3α. We developed monoclonal antibodies that recognize the 7 C-terminal amino acids unique to Stat3β (CT7) and do not cross-react with Stat3α. Immunoblotting studies revealed that levels of Stat3β protein, but not Stat3α, in breast cancer cell lines positively correlated with overall pStat3 levels, suggesting that Stat3β may contribute to constitutive Stat3 activation in this tumor system. The ability to unambiguously discriminate splice alternative Stat3β from proteolytic Stat3β and Stat3α will provide new insights into the contribution of Stat3β vs. Stat3α to oncogenesis, as well as other biological and pathological processes.

  12. Putative contribution of CD56 positive cells in cetuximab treatment efficacy in first-line metastatic colorectal cancer patients

    International Nuclear Information System (INIS)

    Activity of cetuximab, a chimeric monoclonal antibody targeting the epidermal growth factor receptor, is largely attributed to its direct antiproliferative and proapoptotic effects. Antibody-dependent cell-mediated cytotoxicity (ADCC) could be another possible mechanism of cetuximab antitumor effects and its specific contribution on the clinical activity of cetuximab is unknown. We assessed immune cells infiltrate (CD56, CD68, CD3, CD4, CD8, Foxp3) in the primary tumor of metastatic colorectal cancer (mCRC) patients treated with a first-line cetuximab-based chemotherapy in the framework of prospective trials (treatment group) and in a matched group of mCRC patients who received the same chemotherapy regimen without cetuximab (control group). The relationship between intra-tumoral immune effector cells, the K-ras status and the efficacy of the treatment were investigated. We also evaluated in vitro, the ADCC activity in healthy donors and chemonaive mCRC patients and the specific contribution of CD56+ cells. ADCC activity against DLD1 CRC cell line is maintained in cancer patients and significantly declined after CD56+ cells depletion. In multivariate analysis, K-ras wild-type (HR: 4.7 (95% CI 1.8-12.3), p = 0.001) and tumor infiltrating CD56+ cells (HR: 2.6, (95%CI:1.14-6.0), p = 0.019) were independent favourable prognostic factors for PFS and response only in the cetuximab treatment group. By contrast CD56+ cells failed to predict PFS and response in the control group. CD56+ cells, mainly NK cells, may be the major effector of ADCC related-cetuximab activity. Assessment of CD56+ cells infiltrate in primary colorectal adenocarcinoma may provide additional information to K-ras status in predicting response and PFS in mCRC patients treated with first-line cetuximab-based chemotherapy

  13. Smoking cessation programmes in radon affected areas: can they make a significant contribution to reducing radon-induced lung cancers?

    International Nuclear Information System (INIS)

    Domestic radon levels in parts of the UK are sufficiently high to increase the risk of lung cancer in the occupants. Public health campaigns in Northamptonshire, a designated radon affected area with 6.3% of homes having average radon levels over the UK action level of 200 Bq m-3, have encouraged householders to test for radon and then to carry out remediation in their homes, but have been only partially successful. Only 40% of Northamptonshire houses have been tested, and only 15% of householders finding raised levels proceed to remediate. Of those who did remediate, only 9% smoked, compared to a countywide average of 28.8%. This is unfortunate, since radon and smoking combine to place the individual at higher risk by a factor of around 4, and suggests that current strategies to reduce domestic radon exposure are not reaching those most at risk. During 2004-5, the NHS Stop Smoking Services in Northamptonshire assisted 2,808 smokers to quit to the 4-week stage, with some 30% of 4-week quitters remaining quitters at 1 year. We consider whether smoking cessation campaigns make significant contributions to radon risk reduction on their own, by assessing individual occupants' risk of developing lung cancer from knowledge of their age, gender, and smoking habits, together with he radon level in their house. The results demonstrate that smoking cessation programmes have significant added value in radon affected areas, and contribute a greater health benefit than reducing radon levels in the smokers' homes, whilst they remain smokers. Additionally, results are presented from a questionnaire-based survey of quitters, addressing their reasons for seeking help in quitting smoking, and whether knowledge of radon risks influenced this decision. The impact of these findings on future public health campaigns to reduce the impact of radon and smoking are discussed. (author)

    Pancreatic acinar cells of adult mice (≥P60) are resistant to transformation by some of the most robust oncogenic insults including expression of K-Ras oncogenes and loss of p16Ink4a/p19Arf or Trp53 tumor suppressors. Yet, these acinar cells yield pancreatic intraepithelial neoplasias (mPanIN) and ductal adenocarcinomas (mPDAC) if exposed to limited bouts of non-acute pancreatitis, providing they harbor K-Ras oncogenes. Pancreatitis contributes to tumor progression by abrogating the senescence barrier characteristic of low-grade mPanINs. Attenuation of pancreatitis-induced inflammation also accelerates tissue repair and thwarts mPanIN expansion. Patients with chronic pancreatitis display senescent PanINs, if they have received anti-inflammatory drugs. These results put forward the concept that anti-inflammatory treatment of people diagnosed with pancreatitis may reduce their risk of developing PDAC. PMID:21665147

  15. RANKL/RANK/MMP-1 molecular triad contributes to the metastatic phenotype of breast and prostate cancer cells in vitro.

    Directory of Open Access Journals (Sweden)

    Sandra Casimiro

    Full Text Available The osteolytic nature of bone metastasis results from a tumor-driven increased bone resorption. Bone remodeling is orchestrated by the molecular triad RANK-RANKL-OPG. This process is dysregulated in bone metastases, mostly via induction of RANKL by tumor-derived factors. These factors increase expression of RANKL, which induce osteoclast formation, function, and survival, thereby increasing bone resorption. RANK is unexpectedly expressed by cancer cells, and the activation of RANKL-RANK pathway correlates with an increased invasive phenotype. To investigate the interaction between RANK expression in human breast and prostate cancer cells and their pro-metastatic phenotype we analyzed the activation of RANKL-RANK pathway and its effects on cell migration, invasion, gene expression in vitro, and osteolysis-inducing ability in vivo. RANKL activates kinase signaling pathways, stimulates cell migration, increases cell invasion, and up-regulates MMP-1 expression. In vivo, MMP-1 knockdown resulted in smaller x-ray osteolytic lesions and osteoclastogenesis, and decreased tumor burden. Therefore, RANKL inhibition in bone metastatic disease may decrease the levels of the osteoclastogenesis inducer MMP-1, contributing to a better clinical outcome.

  16. A contribution to improved radiotherapy for muscle-invading urinary bladder cancer

    International Nuclear Information System (INIS)

    Due to the possible side-effects of radical cystectomy for muscle-invading urinary bladder cancer (UBC), radiotherapy remains an attractive organ-sparing treatment option, either alone or combined with increasingly effective chemotherapy. Radiation dose escalation may further improve the results obtained with radiotherapy. This Ph.D. program aimed at developing improved conformal radiotherapy techniques required for dose escalation in bladder irradiation. Initially, computer-controlled movement of the collimators during beam delivery was applied to shape partially wedged beams (PWBs), designed to conform the dose distribution to bladder targets. The dosimetric verification and treatment planning implementation of PWBs were addressed. Particular attention was given to dynamic beam isodose verification with the BMS-96 diode array. The theoretical clinical impact of PWBs in bladder irradiation was evaluated in a planning study. Using PWBs the dose homogeneity inside bladder targets improved and normal tissue (small intestine and rectum) doses were reduced. Judged from normal tissue complication probability (NTCP) modeling, PWBs would allow radiation dose escalation with 2-6 Gy in up to 60% of the patients without increasing the estimated combined NTCP relative to the standard setup. This work also demonstrated the uncertainty in intestine and rectum tolerance data and the differences between the various NTCP models. Finally, the internal bladder motion and patient setup variation were quantified from weekly repeat CT scans and electronic portal images, and new bladder treatment margins were derived. Currently, a bladder dose escalation trial using the PWB principle is performed, testing if the whole bladder target dose can be increased from 64 to 68 Gy while maintaining a low level of treatment-induced complications

  17. National dose registry in Switzerland - ten years of experience

    International Nuclear Information System (INIS)

    The Swiss National Dose Registry came into operation 1990. In the ten years of operating, the Registry has proved to be a valuable instrument for monitoring, controlling and registering of occupational radiation exposure in the country. When the Registry was designed, three focal points were taken into account: the Registry should fit in the rather complicated organization of the personal dosimetry in Switzerland, it should allow very high flexibility for future developments (computer and database technologies) and it should be possible to use it actively for different purposes and not only as an archive database. The experience has shown that the features of the Registry that allow fulfilling these conditions are crucial to a perfect operation of the Registry. (author)

    Registries are a topic of lively debate amongst all stakeholders in healthcare, politics and economics. In general, registries are national or international (prospective) databases documenting the current state of diagnostic, therapeutic and long-term outcome variables of subjects with a distinct condition or health problem. The access to and handling of registry information is subject to strict legal, methodological and ethical principles and regulations before these data can be scientifically utilized and reentered into the routine daily practice. Because of the representativeness and reality of data, registries are widely regarded as the backbone of health systems and budgets.Currently there is only indirect evidence that registries influence outcomes and the quality of care. Recent statistical techniques may allow quasi-experimental modelling of observational information. In orthopedic and trauma surgery, current and upcoming registries should be wisely utilized to develop and evaluate innovations and to make informed decisions relevant to care. PMID:27164976

    BACKGROUND: Bone cancer pain seriously affects the quality of life of cancer patients. Our previous study found that endogenous formaldehyde was produced by cancer cells metastasized into bone marrows and played an important role in bone cancer pain. However, the mechanism of production of this endogenous formaldehyde by metastatic cancer cells was unknown in bone cancer pain rats. Lysine-specific demethylase 1 (LSD1) is one of the major enzymes catalyzing the production of formaldehyde. The ...

    Full Text Available Objective: The present study was aimed at evaluating the contribution of transrectal prostate ultrasound in the screening for prostate neoplasias and in the guidance of prostate biopsies. Materials and Methods: Prospective study developed over a one-year period. All the patients with indication for prostate biopsy were evaluated. Regardless of PSA values, the patients underwent ultrasound in order to identify suspicious nodules (confirmed by two observers. Sextant biopsy was subsequently performed. In cases of finding suspicious nodules, an additional puncture directed to such nodules was done. Results: In a total of 155 cases the prevalence of malignancy was of 53%. Suspicious nodules were detected in 34 patients, and 25 where malignant (positive predictive value of 74%. The specificity and sensitivity for suspicious nodules were 88% and 31% respectively. Comparatively with the randomly obtained sextant specimens, the rate of findings of neoplasia was higher in the specimens obtained with puncture directed to the nodule (p = 0.032. No statistically significant difference was observed in the Gleason score for both types of specimens (p = 0.172. Conclusion: The high positive predictive value and the high rate of findings of neoplasia in specimens of suspicious nodules should be taken into consideration in the future. The authors suggest a biopsy technique similar to the one described in the present study (sextant biopsy plus puncture directed to the suspicious nodule.

  4. The national registry for radiation workers

    International Nuclear Information System (INIS)

    The National Registry for Radiation Workers (NRRW) was set up by the National Radiological Protection Board in 1976. The analysis of registry data has four aims: a) To determine whether there is any evidence of differences in the causes of and ages at death of workers exposed to different levels of radiation and, if any differences are found, whether it seems likely that they can be attributed to radiation. b) To estimate the magnitude of the risk, if any differences are found, that seem likely to be attributable to radiation. c) To estimate bounds to the possible risk for particular types of malignancy, such as leukemia. d) To compare the mortality experience of radiation workers with national mortality data and also with that of other industrial groups for whom data exist. If current estimates of the risks of ionizing radiation are correct, very few deaths will be induced in the study population and it will be impossible to detect them statistically. The NRRW currently includes records for over 60,000 individuals. 6 refs

    We previously reported that our novel compound 3β-hydroxy-17-(1H-benzimidazole-1-yl)androsta-5,16-diene (VN/124-1) is a potent CYP17 inhibitor/antiandrogen and strongly inhibits the formation and proliferation of human prostate cancer LAPC4 tumor xenografts in SCID mice. In this study, we report that VN/124-1 and other novel CYP17 inhibitors also cause down-regulation of AR protein expression in vitro and in vivo. This mechanism of action appears to contribute to their antitumor efficacy. We compared the in vivo antitumor efficacy of VN/124-1 with that of castration and a clinically used antiandrogen, casodex, and show that VN/124-1 is more potent than castration in LAPC4 xenograft model. Treatment with VN/124-1 (0.13 mmol/kg/twice daily) was also very effective in preventing the formation of LAPC4 tumors (6.94 vs. 2410.28 mm3 in control group). VN/124-1 (0.13 mmol/kg/twice daily) and VN/124-1 (0.13 mmol/kg/twice daily) + castration induced regression of LAPC4 tumor xenografts by 26.55% and 60.67%, respectively. Treatments with casodex (0.13 mmol/kg/twice daily) or castration caused significant tumor suppression compared with control. Furthermore, treatment with VN/124-1 caused marked down-regulation of AR protein expression, in contrast to treatments with casodex or castration that caused significant up-regulation of AR protein expression. The results suggest that VN/124-1 acts by several mechanisms (CPY17 inhibition, competitive inhibition and down-regulation of the androgen receptor). These actions contribute to inhibition of the formation of LAPC4 tumors and cause regression of growth of established tumors. VN/124-1 is more efficacious than castration in the LAPC4 xenograft model suggesting the compound has potential for the treatment of prostate cancer. PMID:18723482

  7. Diabetes, insulin and cancer risk

    Full Text Available There is a consensus that both type 1 and type 2 diabetes are associated with a spectrum of cancers but the underlying mechanisms are largely unknown. On the other hand, there are ongoing debates about the risk association of insulin use with cancer. We have briefly reviewed recent related research on exploration of risk factors for cancer and pharmacoepidemiological investigations into drug use in diabetes on the risk of cancer, as well as the current understanding of metabolic pathways implicated in intermediary metabolism and cellular growth. Based on the novel findings from the Hong Kong Diabetes Registry and consistent experimental evidence, we argue that use of insulin to control hyperglycemia is unlikely to contribute to increased cancer risk and that dysregulations in the AMP-activated protein kinase pathway due to reduced insulin action and insulin resistance, the insulin-like growth factor-1 (IGF-1-cholesterol synthesis pathway and renin-angiotensin system, presumably due to reduced insulin secretion and hyperglycemia, may play causal roles in the increased risk of cancer in diabetes. Further exploration into the possible causal relationships between abnormalities of these pathways and the risk of cancer in diabetes is warranted.

    Full Text Available BACKGROUND: The contribution of low-penetrant susceptibility variants to cancer is not clear. With the aim of searching for genetic factors that contribute to cancer at one or more sites in the body, we have analyzed familial aggregation of cancer in extended families based on all cancer cases diagnosed in Iceland over almost half a century. METHODS AND FINDINGS: We have estimated risk ratios (RRs of cancer for first- and up to fifth-degree relatives both within and between all types of cancers diagnosed in Iceland from 1955 to 2002 by linking patient information from the Icelandic Cancer Registry to an extensive genealogical database, containing all living Icelanders and most of their ancestors since the settlement of Iceland. We evaluated the significance of the familial clustering for each relationship separately, all relationships combined (first- to fifth-degree relatives and for close (first- and second-degree and distant (third- to fifth-degree relatives. Most cancer sites demonstrate a significantly increased RR for the same cancer, beyond the nuclear family. Significantly increased familial clustering between different cancer sites is also documented in both close and distant relatives. Some of these associations have been suggested previously but others not. CONCLUSION: We conclude that genetic factors are involved in the etiology of many cancers and that these factors are in some cases shared by different cancer sites. However, a significantly increased RR conferred upon mates of patients with cancer at some sites indicates that shared environment or nonrandom mating for certain risk factors also play a role in the familial clustering of cancer. Our results indicate that cancer is a complex, often non-site-specific disease for which increased risk extends beyond the nuclear family.

    Emerging evidence suggested that upregulation of miR-155 could serve as a promising marker for the diagnosis and prognosis of non-small cell lung cancer (NSCLC). In the present study, we genotyped rs767649 (A > T) located in miR-155 regulation region in 1341 cases and 1982 controls, and analyzed the associations of rs767649 with NSCLC risk and survival. Consequently, rs767649 exhibited the significant associations with the risk (adjusted OR = 1.12, 95% CI = 1.01-1.24, P = 0.031) and prognosis of NSCLC (adjusted HR = 1.17, 95% CI = 1.03-1.32, P = 0.014). Meanwhile, rs767649 specifically interacted with radio-chemotherapy (P(int) = 0.013), and patients with both the rs767649-TT genotype and radio-chemotherapy had the highest hazard ratio (adjusted HR = 1.65, 95% CI = 1.26-2.16, P rs767649 variant allele could increase the transcriptional activity of miR-155, which in turn facilitated tumor growth and metastasis by inhibiting HBP1, TJP1, SMAD5 and PRKAR1A expression. Our findings suggested that rs767649 A > T might contribute to the increased risk and poor prognosis of NSCLC, highlighting the importance of rs767649 in the prevention and therapy of NSCLC.

    Although numerous epidemiological studies show aspirin to reduce risk of prostate cancer, the mechanism of this effect is unclear. Here, we first confirmed that aspirin downregulated androgen receptor (AR) and prostate-specific antigen in prostate cancer cells. We also found that aspirin upregulated prostaglandin receptor subtype EP3 but not EP2 or EP4. The EP3 antagonist L798106 and EP3 knockdown increased AR expression and cell proliferation, whereas the EP3 agonist sulprostone decreased them, indicating that EP3 affects AR expression. Additionally, EP3 (PTGER3) transcript levels were significantly decreased in human prostate cancer tissues compared with those in normal human prostate tissues, suggesting that EP3 is important to prostate carcinogenesis. Decreased EP3 expression was also seen in castration-resistant subtype CxR cells compared with parental LNCaP cells. Finally, we found that aspirin and EP3 modulators affected prostate cancer cell growth. Taken together, aspirin suppressed LNCaP cell proliferation via EP3 signaling activation; EP3 downregulation contributed to prostate carcinogenesis and to progression from androgen-dependent prostate cancer to castration-resistant prostate cancer by regulating AR expression. In conclusion, cyclooxygenases and EP3 may represent attractive therapeutic molecular targets in androgen-dependent prostate cancer. PMID:23493387

    The most efficient approach to traumatologic disease is prevention, but physicians also must supervise care of the victims. An operational and effective trauma registry requires financial support, adequate software, a well-defined population, personnel committed to training, and a detailed process for data collection, reporting, validation and the maintenance of confidentiality. Above all, however, motivation is required. Registries can offer many benefits in relation to these highly prevalent disorders, with an impact in terms of health promotion and even advantages in the form of cost reductions, as well as relief from the suffering caused by trauma (mortality, disability)-contributing to improve the efficiency and quality of critical trauma care. The SEMICYUC has demonstrated its ability to establish and maintain records of national interest, and this should become a priority project. PMID:23507334

PURPOSE: Our study describes a reproducible, highly scalable, standard framework for a device registry implementation addressing both local data quality components and global linking problems. METHODS AND RESULTS: We developed a device registry framework involving the following steps: (1 Data standards definition and representation of the research workflow, (2 Development of electronic case report forms using REDCap (Research Electronic Data Capture, (3 Data collection according to the clinical research workflow and, (4 Data augmentation by enriching the registry database with local electronic health records, governmental database and linked open data collections, (5 Data quality control and (6 Data dissemination through the registry Web site. Our registry adopted all applicable standardized data elements proposed by American College Cardiology / American Heart Association Clinical Data Standards, as well as variables derived from cardiac devices randomized trials and Clinical Data Interchange Standards Consortium. Local interoperability was performed between REDCap and data derived from Electronic Health Record system. The original data set was also augmented by incorporating the reimbursed values paid by the Brazilian government during a hospitalization for pacemaker implantation. By linking our registry to the open data collection repository Linked Clinical Trials (LinkedCT we found 130 clinical trials which are potentially correlated with our pacemaker registry.

    Purpose When faced with a significant recruitment challenge for three nationwide psycho-educational trials targeting prostate and breast cancer patients, the Cancer Information Service Research Consortium initiated outreach efforts to increase accrual. Recruitment is reported by major outreach strategy to inform the use of similar campaigns, either as primary recruitment efforts or to supplement “in-reach” recruitment within oncology settings. Methods During a 33-month period, recruitment was tracked from the National Cancer Institute’s Cancer Information Service (CIS), the American Cancer Society (ACS), Dr. Susan Love Research Foundation’s Love/Avon Army of Women (AOW), Internet advertising, press releases, radio/television interviews, recruitment materials in community venues, and outreach to churches and cancer support organizations. Results Across projects, the majority (89%) of recruited participants (N = 2,134) was obtained from the CIS (n = 901, 19 months of recruitment), AOW (n = 869, 18 months), and ACS (n = 123, 12 months). Other efforts showed minimal gain in recruitment. Conclusions Cancer information programs (e.g., CIS, ACS) and registries of individuals willing to participate in cancer-related research (e.g., AOW) can represent exceptional resources for outreach recruitment of cancer patients, especially when the eligibility criteria are highly restrictive. However, these resources do not yield samples representative of the larger population of adults diagnosed with cancer, and conclusions from such trials must be tempered accordingly. Implications for cancer survivors Inadequate recruitment to randomized controlled trials limits the creation of useful interventions for cancer survivors. By enrolling in cancer registries and taking part in research, cancer survivors can contribute to the development of effective resources for the survivor population. PMID:23595235

  5. Chevron Canada Resources voluntary challenge and registry 2000 annual report

    International Nuclear Information System (INIS)

    Chevron Canada Resources has been a registered member of the Voluntary Challenge and Registry (VCR) program since 1995. During the course of 2000, Chevron Canada Resources continued in its efforts toward raising awareness at the employee level concerning the program while it strove to maintain the system previously established called Protecting People and the Environment. Some of the successes experienced by the company in 2000 were: a 6 per cent reduction in flare gas volumes per unit production from the levels of 1990, a 0.3 per cent reduction in total carbon dioxide emissions from the levels of 1999, the elimination of 4,317 tonnes of carbon dioxide equivalent emissions, and the reduction, in 2000, of total carbon dioxide emissions to below year 2001 projections. The forecast for carbon dioxide emissions in 2001 by Chevron Canada Resources is 108 per cent of 1990 levels, which can be explained by a significant increase in more energy intensive products and increasing water volumes in maturing fields. The following initiatives are being implemented to support further improvement in energy and emissions management and the reduction of carbon dioxide emissions: (1) training programs for employees in design and operations, (2) the identification of opportunities within facilities for optimization of energy consumption, (3) a contribution to research and development programs in emissions control and energy efficiency, and (4) the continuous investigating of alternative practices to reduce greenhouse gas emissions and the conservation of resources. 2 tabs., 8 figs

  7. Canadian national dose registry of radiation workers 1951-2007: overview of research

    International Nuclear Information System (INIS)

    The National Dose Registry (NDR) of Canada is a unique resource for direct estimation of health risks associated with low radiation doses. This is the largest national occupational radiation exposure database, as it includes about 600,000 nuclear, industrial, medical and dental workers exposed to the average cumulative dose of several mSv. Analyses of the NDR data based on a cohort of about 200,000 workers first exposed before 1984 and followed through 1987 and 1988 for mortality and cancer incidence respectively, showed that mortality from most causes of death considered, and cancer incidence were lower than those in the general population, which is typical of occupational cohorts. There was a significant increase over the general population in the incidence of thyroid cancer and melanoma (however, this was not certain to be related to radiation exposure). Significant dose-response was found for mortality from all causes, all cancers, lung cancer, circulatory diseases, accidents, for incidence of all cancers, cancers of the rectum and lung, leukaemia, all cancers except lung and all cancers except leukaemia. In addition, in male workers significant dose-response was found for the incidence of colon, pancreatic and testicular cancers. Estimates of cancer risks based on mortality and incidence were higher than those in most other occupational cohorts and in the Atomic bomb survivors studies. Biologically-based analysis of lung cancer incidence in the NDR showed that for protracted exposure to low radiation doses there was a significant radiation effect on promotion and malignant conversion, but not on the initiation stage of carcinogenesis. This is in contrast to the findings for high-dose acute exposures in Atomic bomb survivors, where initiation and possibly promotion was found to be affected by radiation exposure. An inverse-dose-rate effect, i.e. increase in risk with protraction of a given dose, was found in the NDR cohort. (author)

    RAD51C, a RAD51 paralogue involved in homologous recombination, is a recently established Fanconi anemia and breast cancer predisposing factor. In the initial report, RAD51C mutations were shown to confer a high risk for both breast and ovarian tumors, but most of the replication studies published so far have failed to identify any additional susceptibility alleles. Here, we report a full mutation screening of the RAD51C gene in 147 Finnish familial breast cancer cases and in 232 unselected ovarian cancer cases originating from Finland and Sweden. In addition, in order to resolve whether common RAD51C SNPs are risk factors for breast cancer, we genotyped five tagging single nucleotide polymorphisms, rs12946522, rs304270, rs304283, rs17222691, and rs28363312, all located within the gene, from 993 Finnish breast cancer cases and 871 controls for cancer associated variants. Whereas, none of the studied common SNPs associated with breast cancer susceptibility, mutation analysis revealed two clearly pathogenic alterations. RAD51C c.-13_14del27 was observed in one familial breast cancer case and c.774delT in one unselected ovarian cancer case, thus confirming that RAD51C mutations are implicated in breast and ovarian cancer predisposition, although their overall frequency seems to be low. Independent identification of the very recently reported RAD51C c.774delT mutation in yet another patient originating from Sweden suggests that it might be a recurrent mutation in that population and should be studied further. The reliable estimation of the clinical implications of carrying a defective RAD51C allele still requires the identification of additional mutation positive families. PMID:21750962

    2015-12-01

    The Anesthesia Quality Institute (AQI) was chartered in 2008 by the American Society of Anesthesiologists to develop the National Anesthesia Clinical Outcomes Registry (NACOR). In this Technical Communication, we will describe how data enter NACOR, how they are authenticated, and how they are analyzed and reported. NACOR accepts case-level administrative, clinical, and quality capture data from voluntarily participating anesthesia practices and health care facilities in the United States. All data are transmitted to the AQI in summary electronic files generated by billing, quality capture, and electronic health care record software, typically on a monthly basis. All data elements are mapped to fields in the NACOR schema in accordance with a publicly available data dictionary. Incoming data are loaded into NACOR by AQI technologists and are subject to both manual and automated review to identify systematically missing elements, miscoding, and inadvertent corruption. Data are deidentified in compliance with Health Insurance Portability and Accountability Act regulations. The database server of AQI, which houses the NACOR database, is protected by 2 firewalls within the American Society of Anesthesiologists' network infrastructure; this system has not been breached. The NACOR Participant User File, a deidentified case-level dataset of information from NACOR, is available to researchers at participating institutions. NACOR architecture and the nature of the Participant User File include both strengths and weaknesses. PMID:26579661

    International Nuclear Information System (INIS)

    Objectives: Forty sites were involved in this multicenter and multivendor registry, which sought to evaluate indications, spectrum of protocols, impact on clinical decision making and safety profile of cardiac magnetic resonance (CMR). Materials and methods: Data were prospectively collected on a 6-month period and included 3376 patients (47.2 ± 19 years; range 1–92 years). Recruited centers were asked to complete a preliminary general report followed by a single form/patient. Referral physicians were not required to exhibit any specific certificate of competency in CMR imaging. Results: Exams were performed with 1.5 T scanners in 96% of cases followed by 3 T (3%) and 1 T (1%) magnets and contrast was administered in 84% of cases. The majority of cases were performed for the workup of inflammatory heart disease/cardiomyopathies representing overall 55.7% of exams followed by the assessment of myocardial viability and acute infarction (respectively 6.9% and 5.9% of patients). In 49% of cases the final diagnosis provided was considered relevant and with impact on patient's clinical/therapeutic management. Safety evaluation revealed 30 (0.88%) clinical events, most of which due to patient's preexisting conditions. Radiological reporting was recorded in 73% of exams. Conclusions: CMR is performed in a large number of centers in Italy with relevant impact on clinical decision making and high safety profile

    Background This article summarizes the 2012 European Renal Association—European Dialysis and Transplant Association Registry Annual Report (available at www.era-edta-reg.org) with a specific focus on older patients (defined as ≥65 years). Methods Data provided by 45 national or regional renal registries in 30 countries in Europe and bordering the Mediterranean Sea were used. Individual patient level data were received from 31 renal registries, whereas 14 renal registries contributed data in an aggregated form. The incidence, prevalence and survival probabilities of patients with end-stage renal disease (ESRD) receiving renal replacement therapy (RRT) and renal transplantation rates for 2012 are presented. Results In 2012, the overall unadjusted incidence rate of patients with ESRD receiving RRT was 109.6 per million population (pmp) (n = 69 035), ranging from 219.9 pmp in Portugal to 24.2 pmp in Montenegro. The proportion of incident patients ≥75 years varied from 15 to 44% between countries. The overall unadjusted prevalence on 31 December 2012 was 716.7 pmp (n = 451 270), ranging from 1670.2 pmp in Portugal to 146.7 pmp in the Ukraine. The proportion of prevalent patients ≥75 years varied from 11 to 32% between countries. The overall renal transplantation rate in 2012 was 28.3 pmp (n = 15 673), with the highest rate seen in the Spanish region of Catalonia. The proportion of patients ≥65 years receiving a transplant ranged from 0 to 35%. Five-year adjusted survival for all RRT patients was 59.7% (95% confidence interval, CI: 59.3–60.0) which fell to 39.3% (95% CI: 38.7–39.9) in patients 65–74 years and 21.3% (95% CI: 20.8–21.9) in patients ≥75 years.

    Registries for rare diseases provide a tool for obtaining an overview of the clinical situation and can be used to discover points of improvement and to monitor long-term safety. Registries could also become a powerful tool to provide supporting information for marketing authorization. There is an urgent need for a pan-European or global strategy that supports consistent data. Therefore, transparency in data collection, harmonization of the database structures, and the convergence of scientific approaches are required. PMID:25669198

    Cancer stem cells (CSCs) have been identified in various types of cancer; however, the mechanisms by which cells acquire CSC properties such as drug resistance and tumour seeding ability are not fully understood. Here, we identified microRNA-27b (miR-27b) as a key regulator for the generation of a side-population in breast cancer cells that showed CSC properties, and also found that the anti-type II diabetes (T2D) drug metformin reduced this side-population via miR-27b-mediated repression of ...

    Cold atmospheric plasma (CAP) has been proposed as a useful cancer treatment option after showing higher induction of cell death in cancer cells than in normal cells. Although a few studies have contributed to elucidating the molecular mechanism by which CAP differentially inhibits cancer cell proliferation, no results are yet to be reported related to microRNA (miR). In this study, miR-19a-3p (miR-19a) was identified as a mediator of the cell proliferation-inhibitory effect of CAP in the MCF-7 breast cancer cell. CAP treatment of MCF-7 induced hypermethylation at the promoter CpG sites and downregulation of miR-19a, which was known as an oncomiR. The overexpression of miR-19a in MCF-7 increased cell proliferation, and CAP deteriorated the effect. The target genes of miR-19a, such as ABCA1 and PTEN, that had been suppressed by miR recovered their expression through CAP treatment. In addition, an inhibitor of reactive oxygen species that is produced by CAP suppressed the effect of CAP on cell proliferation. Taken together, the present study, to the best of authors’ knowledge, is the first to identify the involvement of a miR, which is dysregulated by the CAP and results in the anti-proliferation effect of CAP on cancer cells.

  7. Canadian National Dose Registry of radiation workers: overview of research from 1951 through 2007

    International Nuclear Information System (INIS)

    The National Dose Registry (NDR) of Canada is a unique resource for a direct estimation of the potential health risks associated with low doses of ionizing radiation. This is the largest national occupational radiation exposure database, comprising with about 600000 records for nuclear, industrial, medical and dental workers. An analysis of NDR data based on a cohort 200000 workers first exposed before 1984 and 1988 for mortality and cancer incidence, respectively, revealed that the mortality from most causes of death considered was than that in the general population, which is typical of occupational cohorts. Although the same was also observed for cancer incidence, there was a significant increase in the incidence of thyroid cancer and melanoma which, however, was not clearly related to radiation exposure. A significant dose-response was found for mortality from all causes, all cancers, lung cancer, cardiovascular diseases, accidents, for incidence of all cancers, leukaemia, all cancers except lung, and all cancers except leukaemia. In addition, in male workers, a significant dose response was found for the incidence of colon, pancreatic and testicular cancers. The estimates of cancer risks (mortality and incidence) were higher those in most other occupational cohorts and in the studies on atomic bomb survivors. The biologically based dose-response models used to describe lung cancer incidence in the NDR showed that for a protracted exposure to low radiation doses there was a significant radiation effect on the promotion and malignant conversion, but not on the initiation stage of carcinogenesis.This stands in contrast for high-dose acute exposures in A-bomb survivors, where the initiation and possibly promotion were found to be affected by radiation exposure. Evidence of an inverse dose-effect (i.e an increase in the risk with a protraction of a given cumulative dose) was found in the NDR cohort. (author)

    Tamoxifen is the accepted therapy for patients with estrogen receptor-α (ERα)-positive breast cancer. However, clinical resistance to tamoxifen, as demonstrated by recurrence or progression on therapy, is frequent and precedes death from metastases. To improve breast cancer treatment it is vital to understand the mechanisms that result in tamoxifen resistance. This study shows that concentrations of tamoxifen and its metabolites, which accumulate in tumors of patients, killed both ERα-positiv...

  9. Reactive oxygen species-mediated apoptosis contributes to chemosensitization effect of saikosaponins on cisplatin-induced cytotoxicity in cancer cells

    2010-12-01

    Full Text Available Abstract Background Saikosaponin-a and -d, two naturally occurring compounds derived from Bupleurum radix, have been shown to exert anti-cancer activity in several cancer cell lines. However, the effect of combination of saikosaponins with chemotherapeutic drugs has never been addressed. Thus, we investigated whether these two saikosaponins have chemosensitization effect on cisplatin-induced cancer cell cytotoxicity. Methods Two cervical cancer cell lines, HeLa and Siha, an ovarian cancer cell line, SKOV3, and a non-small cell lung cancer cell line, A549, were treated with saikosaponins or cisplatin individually or in combination. Cell death was quantitatively detected by the release of lactate dehydrogenase (LDH using a cytotoxicity detection kit. Cellular ROS was analyzed by flow cytometry. Apoptosis was evaluated by AO/EB staining, flow cytometry after Anexin V and PI staining, and Western blot for caspase activation. ROS scavengers and caspase inhibitor were used to determine the roles of ROS and apoptosis in the effects of saikosaponins on cisplatin-induced cell death. Results Both saikosaponin-a and -d sensitized cancer cells to cisplatin-induced cell death in a dose-dependent manner, which was accompanied with induction of reactive oxygen species (ROS accumulation. The dead cells showed typical apoptotic morphologies. Both early apoptotic and late apoptotic cells detected by flow cytometry were increased in saikosaponins and cisplatin cotreated cells, accompanied by activation of the caspase pathway. The pan-caspase inhibitor z-VAD and ROS scanvengers butylated hydroxyanisole (BHA and N-acetyl-L-cysteine (NAC dramatically suppressed the potentiated cytotoxicity achieved by combination of saikosaponin-a or -d and cisplatin. Conclusions These results suggest that saikosaponins sensitize cancer cells to cisplatin through ROS-mediated apoptosis, and the combination of saikosaponins with cisplatin could be an effective therapeutic strategy.

    Epigenetics is the study of heritable changes in gene expression that occur without a change in DNA sequence. Cancer is a multistep process derived from combinational crosstalk between genetic alterations and epigenetic influences through various environmental factors. The observation that epigenetic changes are reversible makes them an attractive target for cancer prevention. Until recently, there have been difficulties studying epigenetic mechanisms in interactions between dietary factors a...

  11. Loss of p53 attenuates the contribution of IL-6 deletion on suppressed tumor progression and extended survival in Kras-driven murine lung cancer.

    Full Text Available Interleukin-6 (IL-6 is involved in lung cancer tumorigenesis, tumor progression, metastasis, and drug resistance. Previous studies show that blockade of IL-6 signaling can inhibit tumor growth and increase drug sensitivity in mouse models. Clinical trials in non-small cell lung cancer (NSCLC reveal that IL-6 targeted therapy relieves NSCLC-related anemia and cachexia, although other clinical effects require further study. We crossed IL-6(-/- mice with Kras(G12D mutant mice, which develop lung tumors after activation of mutant Kras(G12D, to investigate whether IL-6 inhibition contributes to tumor progression and survival time in vivo. Kras(G12D; IL-6(-/- mice exhibited increased tumorigenesis, but slower tumor growth and longer survival, than Kras(G12D mice. Further, in order to investigate whether IL-6 deletion contributes to suppression of lung cancer metastasis, we generated Kras(G12D; p53(flox/flox; IL-6(-/- mice, which developed lung cancer with a trend for reduced metastases and longer survival than Kras(G12D; p53(flox/flox mice. Tumors from Kras(G12D; IL-6(-/- mice showed increased expression of TNFα and decreased expression of CCL-19, CCL-20 and phosphorylated STAT3(pSTAT3 than Kras(G12D mice; however, these changes were not present between tumors from Kras(G12D; p53(flox/flox; IL-6(-/- and Kras(G12D; p53(flox/flox mice. Upregulation of pSTAT3 and phosphorylated AKT(pAKT were observed in Kras(G12D tumors with p53 deletion. Taken together, these results indicate that IL-6 deletion accelerates tumorigenesis but delays tumor progression and prolongs survival time in a Kras-driven mouse model of lung cancer. However, these effects can be attenuated by p53 deletion.

    Full Text Available Abstract Background Disability-adjusted life years (DALYs link data on disease occurrence to health outcomes, and they are a useful aid in establishing country-specific agendas regarding cancer control. The variables required to compute DALYs are however multiple and not readily available in many countries. We propose a methodology that derives global DALYs and validate variables and DALYs based on data from various cancer registries. Methods We estimated DALYs for four countries (Norway, Bulgaria, India and Uganda within each category of the human development index (HDI. The following sources (indicators were used: Globocan2008 (incidence and mortality, various cancer registries (proportion cured, proportion treated and duration of disease, treatment guidelines (duration of treatment, specific burden of disease studies (sequelae and disability weights, alongside expert opinion. We obtained country-specific population estimates and identified resource levels using the HDI, DALYs are computed as the sum of years of life lost and years lived with disabilities. Results Using mortality:incidence ratios to estimate country-specific survival, and by applying the human development index we derived country-specific estimates of the proportion cured and the proportion treated. The fit between the estimates and observed data from the cancer registries was relatively good. The final DALY estimates were similar to those computed using observed values in Norway, and in WHO’s earlier global burden of disease study. Marked cross-country differences in the patterns of DALYs by cancer sites were observed. In Norway and Bulgaria, breast, colorectal, prostate and lung cancer were the main contributors to DALYs, representing 54% and 45%, respectively, of the totals. These cancers contributed only 27% and 18%, respectively, of total DALYs in India and Uganda. Conclusions Our approach resulted in a series of variables that can be used to estimate country

  14. Sanitary surveillance in France in relation with the Chernobylsk accident. Updated situation on thyroid cancers and epidemiological studies during 2006

    International Nuclear Information System (INIS)

    An increase in the incidence of thyroid cancer in children has been reported since 1990 in areas of Belarus, Russia and Ukraine which have been highly contaminated during the Chernobyl accident in 1986. A similar increase is now observed in young adults in the same areas. In France, thyroid cancer is characterized by low occurrence and good prognosis. However, the incidence of thyroid cancer has been increasing for more than 20 years, and in 1986, the Chernobyl cloud of radioactive dust crossed the French territory. Thus, the National institute for public health surveillance (I.n.V.S.) carried out several studies to evaluate whether the incidence increase in thyroid cancer is related to radiation exposure from the Chernobyl accident. Since 2000, the I.n.V.S. is in charge of a national multidisciplinary approach involving a wide range of public health actors, including the French network of cancer registries (Francim). Since 2003, the I.n.V.S. has been working on improving the surveillance system according to the actions described in the national cancer plan 2003-2007. The I.n.V.S. has increased its financial contribution to cancer registries including the national registry of solid tumors in children, which was created in 2000. The Institute is also working on the implementation of a multi source system for the national cancer surveillance in link with cancer registries. For the twentieth anniversary of the Chernobyl accident, the I.n.V.S. is publishing updated results from the latest research conducted in close collaboration with the partners. These results do not support the initial hypothesis of a potential 'Chernobyl effect' in France. The increase in the incidence of thyroid cancer is also reported in most of developed countries. Practices in cancer diagnosis and the increased rate of total thyroidectomy for benign lesion may lead pathologists to unexpectedly discover small thyroid tumors. This fact is likely to explain most of the incidence increase. The wide

    Leptin, a cytokine produced by the adipose tissue in response to food intake, is a key player in the regulation of energy balance and body weight control. Physiological action of leptin in modulating the metabolic adaptation of different peripheral tissues supports the hypothesis that it could also exert a direct effect on cancer cells. In vitro, treatment with leptin up-regulated HIF-1α and stimulated adhesion and invasion of prostate cancer cells cultured in hypoxia. Leptin action was effective in both low and high glycolytic cancer cell lines, and determined the up-regulation of lactate exporter MCT4 and its associated protein CD147. HIF-1α stabilization was oligomycin-independent and was associated with an important modulation of mitochondrial homeostasis. In fact, leptin treatment produced mitochondrial biogenesis, stabilization of mitochondrial membrane potential and increased uncoupled respiration through the up-regulation of UCP2. Furthermore, leptin counteracted the downmodulation of SIRT1 induced by hypoxia, and persistent high levels of SIRT1 were directly involved in HIF-1α stabilization. Leptin can sustain cancer progression in hypoxic environment and when mitochondrial respiration is impaired. Leptin signaling axis, including the new proposed intermediate SIRT1, could represent a new diagnostic and therapeutic target in prostate cancer. PMID:26996298

    Objective Metabolomic research has revealed that metabolites play an important role in prostate cancer development and progression. Previous studies have suggested that prostate cancer cell proliferation is induced by advanced glycation end products (AGEs) exposure, but the mechanism of this induction remains unknown. This study aim to investigate the molecular mechanisms underlying the proliferative response of prostate cancer cell to the interaction of AGEs and the receptor for advanced glycation end products (RAGE). Methods To investigate this mechanism, we used Western blotting to evaluate the responses of the retinoblastoma (Rb), p-Rb and PI3K/Akt pathway to AGEs stimulation. We also examined the effect of knocking down Rb and blocking the PI3K/Akt pathway on AGEs induced PC-3 cell proliferation. Results Our results indicated that AGE-RAGE interaction enhanced Rb phosphorylation and subsequently decreased total Rb levels. Bioinformatics analysis further indicated a negative correlation between RAGE and RB1 expression in prostate cancer tissue. Furthermore, we observed that AGEs stimulation activated the PI3K/Akt signaling pathway and that blocking PI3K/Akt signaling abrogated AGEs-induced cell proliferation. Conclusions We report, for the first time, that AGE-RAGE interaction enhances prostate cancer cell proliferation by phosphorylation of Rb via the PI3K/Akt signaling pathway.

    Full Text Available Early detection of cancer is an effective and efficient cancer management strategy. In South Korea, the National Health Insurance administers the National Cancer Screening Program to its beneficiaries. We examined the impact of the National Cancer Screening Program on socioeconomic disparities in cancer stage at diagnosis.Cancer patients registered in the Korean Central Cancer Registry from January 1, 2010 to December 31, 2010 with a diagnosis of gastric cancer (n = 22,470, colon cancer (n = 16,323, breast cancer (n = 10,076, or uterine cervical cancer (n = 2,447 were included. Income level was divided into three groups according to their monthly contribution of National Health Insurance. We employed absolute (age-standardized prevalence rate, slope index of inequality and relative (relative index of inequality measures to separately examine social disparities among participants and non-participants of the National Cancer Screening Program in terms of the early-stage rate.Age-standardized prevalence rates of early-stage by income group were always higher in participants than in non-participants. Furthermore, the age-standardized prevalence rate of early-stage in the low income group of the participants was also higher than that of the high income group of the non-participants. The sizes of disparities (both slope index of inequality and relative index of inequality are smaller in participants compared to non-participants.National Cancer Screening Program participation reduced income disparity in cancer stage at diagnosis. Population-based cancer screening programs can be used as an effective measure to reduce income disparity in cancer care.

    β-1,4-Galactosyltransferase III (B4GALT3) is an enzyme responsible for the generation of poly-N-acetyllactosamine and is involved in tumorigenesis. However, B4GALT3-dysregulation and its role in cervical cancer cells are unknown. Herein, we found that B4GALT3 was upregulated in cervical cancer tissues compared to adjacent non-tumor tissues. B4GALT3-overexpression promoted, whereas B4GALT3-knockdown suppressed the cellular migration, invasion and EMT of HeLa and C33A cervical cancer cells. To explore the mechanism of dysregulation, B4GALT3 was predicted to be a target of miR-27a. EGFP and pGL3-promoter reporter assay showed miR-27a binds to B4GALT3 3'UTR region but enhanced its expression. RT-qPCR showed miR-27a was also upregulated and presented positive correlation with B4GALT3-expression in cervical cancer tissues. miR-27a-overexpression promoted, but blocking-miR-27a repressed these malignancies in HeLa and C33A cells. Furthermore, shR-B4GALT3 counteracted the promotion of malignancies induced by miR-27a, suggesting miR-27a upregulates B4GALT3 to enhance tumorigenic activities. In addition, we found that B4GALT3 significantly enhances β1-integrin stability, thus mediating promotion of B4GALT3 on malignancy in cervical cancer cells. Altogether, our findings evidenced that B4GALT3 upregulated by miR-27a contributes to the tumorigenic activities by β1-integrin pathway and might provide potential biomarkers for cervical cancer.

    Human Mena (hMENA), an actin regulatory protein of the ENA/VASP family, cooperates with ErbB receptor family signaling in breast cancer. It is overexpressed in high-risk preneoplastic lesions and in primary breast tumors where it correlates with HER2 overexpression and an activated status of AKT and MAPK. The concomitant overexpression of hMENA and HER2 in breast cancer patients is indicative of a worse prognosis. hMENA is expressed along with alternatively expressed isoforms, hMENA(11a) and hMENAΔv6 with opposite functions. A novel role for the epithelial-associated hMENA(11a) isoform in sustaining HER3 activation and pro-survival pathways in HER2-overexpressing breast cancer cells has been identified by reverse phase protein array and validated in vivo in a series of breast cancer tissues. As HER3 activation is crucial in mechanisms of cell resistance to PI3K inhibitors, we explored whether hMENA(11a) is involved in these resistance mechanisms. The specific hMENA(11a) depletion switched off the HER3-related pathway activated by PI3K inhibitors and impaired the nuclear accumulation of HER3 transcription factor FOXO3a induced by PI3K inhibitors, whereas PI3K inhibitors activated hMENA(11a) phosphorylation and affected its localization. At the functional level, we found that hMENA(11a) sustains cell proliferation and survival in response to PI3K inhibitor treatment, whereas hMENA(11a) silencing increases molecules involved in cancer cell apoptosis. As shown in three-dimensional cultures, hMENA(11a) contributes to resistance to PI3K inhibition because its depletion drastically reduced cell viability upon treatment with PI3K inhibitor BEZ235. Altogether, these results indicate that hMENA(11a) in HER2-overexpressing breast cancer cells sustains HER3/AKT axis activation and contributes to HER3-mediated resistance mechanisms to PI3K inhibitors. Thus, hMENA(11a) expression can be proposed as a marker of HER3 activation and resistance to PI3K inhibition therapies, to

  3. Contribution of 18F-fluorodeoxyglucose positron emission tomography in the detection and evaluation of peritoneal metastasis in colorectal cancer

    International Nuclear Information System (INIS)

    Accurate detection of peritoneal metastasis in colorectal cancer remains a diagnostic challenge. The accuracy of 18F-fluorodeoxyglucose positron emission tomography (FDG-PET) in the diagnosis of peritoneal recurrence was evaluated, FDG-PET was conducted in 18 patients previously treated for colorectal cancer and suspected recurrence with clinical symptoms, computed tomography (CT), and tumor markers. Final Diagnosis was obtained by histological evaluation (n=14) or clinical follow-up (n=4). FDG-PET sensitivity was 88%, and accuracy in detecting peritoneal recurrence was 78%. For CT scans, sensitivity was 38% and accuracy 44% Six patients were suspected to have peritoneal recurrence based on FDG-PET and 5 were identified pathologically with peritoneal metastasis. Lesions smaller than 30 mm were not detected by CT. FDG-PET detected 15 mm lesions. In conclusion, FDG-PET is an accurate, noninvasive way to detect peritoneal recurrence in colorectal cancer and would play an important role in clinical management. (author)

    RNA helicase DDX5 (also p68) is involved in all aspects of RNA metabolism and serves as a transcriptional co-regulator, but its functional role in breast cancer remains elusive. Here, we report an integrative biology study of DDX5 in breast cancer, encompassing quantitative proteomics, global MicroRNA profiling, and detailed biochemical characterization of cell lines and human tissues. We showed that protein expression of DDX5 increased progressively from the luminal to basal breast cancer cell lines, and correlated positively with that of CD44 in the basal subtypes. Through immunohistochemistry analyses of tissue microarrays containing over 200 invasive human ductal carcinomas, we observed that DDX5 was upregulated in the majority of malignant tissues, and its expression correlated strongly with those of Ki67 and EGFR in the triple-negative tumors. We demonstrated that DDX5 regulated a subset of MicroRNAs including miR-21 and miR-182 in basal breast cancer cells. Knockdown of DDX5 resulted in reorganization of actin cytoskeleton and reduction of cellular proliferation. The effects were accompanied by upregulation of tumor suppressor PDCD4 (a known miR-21 target); as well as upregulation of cofilin and profilin, two key proteins involved in actin polymerization and cytoskeleton maintenance, as a consequence of miR-182 downregulation. Treatment with miR-182 inhibitors resulted in morphologic phenotypes resembling those induced by DDX5 knockdown. Using bioinformatics tools for pathway and network analyses, we confirmed that the network for regulation of actin cytoskeleton was predominantly enriched for the predicted downstream targets of miR-182. Our results reveal a new functional role of DDX5 in breast cancer via the DDX5→miR-182→actin cytoskeleton pathway, and suggest the potential clinical utility of DDX5 and its downstream MicroRNAs in the theranostics of breast cancer.

    Ovarian cancer is a gynecological malignancy with high mortality rates worldwide and novel diagnostic and prognostic markers and therapeutic targets are urgently required. The suppressor of cytokine signaling 1 (SOCS1) and cyclin-dependent kinase inhibitor 1A (p21(KIP)) are known to regulate tumor cell proliferation. However, the mechanisms that regulate these genes have not yet been completely elucidated. In the present study, analysis of a published microarray-based high-throughput assessment (NCBI/E-MTAB-1067) and real-time PCR demonstrated that miR-572 was upregulated in human ovarian cancer tissues and cell lines. Kaplan-Meir analysis indicated that high level expression of miR-572 was associated with poorer overall survival. Ectopic miR-572 promoted ovarian cancer cell proliferation and cell cycle progression in vitro and tumorigenicity in vivo. SOCS1 and p21 were identified as direct targets of miR-572 and suppression of SOCS1 or p21 reversed the inhibiting-function of miR-572-silenced cell on proliferation and tumorigenicity in ovarian cancer cells. Additionally, the expression of miR-572 correlated inversely with the protein expression levels of SOCS1, p21 and positively with Cyclin D1 in ovarian carcinoma specimens. This study demonstrates that miR-572 post-transcriptionally regulates SOCS1 and p21 and may play an important role in ovarian cancer progression; miR-572 may represent a potential therapeutic target for ovarian cancer therapy.

    The aim of this study is to determine how complications can be avoided in gynecological minimally invasive surgery in Europe. The Norwegian Gynecological Endoscopic Registry (NGER) facilitates medical research over a long duration. Can experiences from the Norwegian registry be used to develop a European registry to avoid complications? To answer this question, we used the NGER data from February 2013 until March 2015 to analyze the complications of gynecological endoscopy. The registry includes sociodemographic factors, related comorbidity, previous surgery, present procedure, and intraoperative complications. Postoperative complications were identified with a questionnaire administered 4 weeks after surgery. The risk factors leading to complications in gynecological endoscopy were found to be obesity, diabetes mellitus, heart disease, hypertension, previous surgery due to cervical carcinoma in situ, and low educational level. Regional differences in the complication rate were noted. National web-based operation registries such as the NGER can identify the risk factors for complications of gynecological endoscopic surgery and can help improve the outcome after surgery. The experience from NGER can be used to establish a European register. PMID:26805611

Materials and Methods: MEDLINE and Web of science electronic database was searched from January 1995 to December 2013, using the using keywords "laryngeal cancer, laryngeal cancer outcome, epidemiology, etiological factor and their corresponding Mesh terms were used in combination like OR, AND." Two authors independently selected studies published in English and conducted in India. A total of 15 studies were found to be relevant and eligible for this review. Results: In India, laryngeal cancer contributes to approximately 3-6% of all cancers in men. The age-adjusted incidence rate of cancer larynx in males varies widely among registries, highest is 8.18 per 100,000 in Kamprup Urban District and the lowest is 1.26 per 100,000 in Nagaland. The 5-year survival for laryngeal cancer in India is approximately 28%. Indian studies show tobacco, alcohol, long-term exposure to indoor air pollution, spicy food, and nonvegetarian diet as risk factors for laryngeal cancer. Conclusion: There is wide regional variation in the incidence of laryngeal cancer in India. Survival rates of laryngeal carcinoma are much lower as compared to other Asian countries. Studies conducted in India to identify important risk factors of laryngeal cancer are very limited, especially on diet and indoor air pollution. Hence, more research is required for identifying the etiological factors and development of scientifically sound laryngeal cancer prevention programs.

  18. Tumor suppressive microRNA-133a regulates novel targets: Moesin contributes to cancer cell proliferation and invasion in head and neck squamous cell carcinoma

    International Nuclear Information System (INIS)

    Highlights: ► Tumor suppressive microRNA-133a regulates moesin (MSN) expression in HNSCC. ► Silencing of MSN in HNSCC cells suppressed proliferation, migration and invasion. ► The expression level of MSN was significantly up-regulated in cancer tissues. -- Abstract: Recently, many studies suggest that microRNAs (miRNAs) contribute to the development, invasion and metastasis of various types of human cancers. Our recent study revealed that expression of microRNA-133a (miR-133a) was significantly reduced in head and neck squamous cell carcinoma (HNSCC) and that restoration of miR-133a inhibited cell proliferation, migration and invasion in HNSCC cell lines, suggesting that miR-133a function as a tumor suppressor. Genome-wide gene expression analysis of miR-133a transfectants and TargetScan database showed that moesin (MSN) was a promising candidate of miR-133a target gene. MSN is a member of the ERM (ezrin, radixin and moesin) protein family and ERM function as cross-linkers between plasma membrane and actin-based cytoskeleton. The functions of MSN in cancers are controversial in previous reports. In this study, we focused on MSN and investigated whether MSN was regulated by tumor suppressive miR-133a and contributed to HNSCC oncogenesis. Restoration of miR-133a in HNSCC cell lines (FaDu, HSC3, IMC-3 and SAS) suppressed the MSN expression both in mRNA and protein level. Silencing study of MSN in HNSCC cell lines demonstrated significant inhibitions of cell proliferation, migration and invasion activities in si-MSN transfectants. In clinical specimen with HNSCC, the expression level of MSN was significantly up-regulated in cancer tissues compared to adjacent non-cancerous tissues. These data suggest that MSN may function as oncogene and is regulated by tumor suppressive miR-133a. Our analysis data of novel tumor-suppressive miR-133a-mediated cancer pathways could provide new insights into the potential mechanisms of HNSCC oncogenesis.

  19. Contribution of the PET-CT with 18F.D.G. in the non metastatic thyroid cancers with suspicion of residual or recurrent disease

    International Nuclear Information System (INIS)

    Purpose: Recurrent thyroid carcinomas usually involve the cervical lymph nodes. The objective of this study was to evaluate the contribution of 18F-F.D.G. PET in the investigation of thyroid cancer compared with non-metastatic cervical echography. Conclusions: Due to the low overall sensitivity of PET / CT in thyroid carcinoma, its use should be reserved for cases of aggressive carcinoma and when the residual thyroglobulin under stimulation is high. In these cases it is a complementary information with neck echography. (N.C.)

    2016-01-01

    Background In 2000, the Food and Drug Administration (FDA) approved gemtuzumab ozogamycin for monotherapy for older patients with relapsed AML. A 0.9% rate of hepatic sinusoidal obstructive syndrome (SOS) was noted in licensing trials. In 2001, FDA received reports of 14 GO-associated SOS cases from MD Anderson Cancer Center. A State of South Carolina/National Cancer Institute funded pharmacovigilance program and a manufacturer sponsored registry independently evaluated this concern. Methods The manufacturer’s registry and the academic program focused on risk factors and incidence of GO-associated SOS in routine clinical practice and clinical trial settings, respectively. Comparisons were made of findings and dissemination efforts from the two studies. Results Retrospective analysis of clinical trials by the academic initiative identified 99 cases of SOS among 221 GO-treated stem cell patients and 649 patients who did not undergo HSCTs. SOS rates were 3% when GO was administered at doses ≤6 mg/m2 as monotherapy or with non-hepatotoxic agents; 28% when administered with 6-thioguanine, a hepatotoxic agent; 15% when administered as monotherapy at doses at a dose of 9 mg/m2, and between 15% and 40% if a stem cell transplant (SCT) was performed within 3 months of GO administration. Death from SOS occurred in 33% of the cases. The manufacturer’s registry prospectively evaluated 482 GO-treated patients who received a mean dose of 7.8 mg/m2. Overall, 41% received concomitant chemotherapy, 18% had undergone prior SCT, 9.1% developed SOS, and death from SOS occurred in 60% of the SOS cases. Findings from each initiative were disseminated at national conferences and in peer-reviewed manuscripts beginning in 2003. Conclusion Retrospective review of clinical trials, case series, and FDA reports and prospective registries can provide important information on safety signals initially identified in licensing trials.

    2015-07-01

    Progesterone (P4) has emerged as an important hormone-regulating mammary stem cell (MaSC) populations. In breast cancer, P4 and synthetic analogs increase the number of stem-like cells within luminal estrogen receptor (ER)- and progesterone receptor (PR)-positive breast cancers. These cells gain expression of de-differentiated cell markers CD44 and cytokeratin 5 (CK5), lose luminal markers ER and PR, and are more therapy resistant. We previously described that P4 downregulation of microRNA (miR)-29a contributes to the expansion of CD44(high) and CK5(+) cells. Here we investigated P4 downregulation of miR-141, a member of the miR-200 family of tumor suppressors, in facilitating an increase in stem-like breast cancer cells. miR-141 was the sole member of the miR-200 family P4-downregulated at the mature miRNA level in luminal breast cancer cell lines. Stable inhibition of miR-141 alone increased the CD44(high) population, and potentiated P4-mediated increases in both CD44(high) and CK5(+) cells. Loss of miR-141 enhanced both mammosphere formation and tumor initiation. miR-141 directly targeted both PR and signal transducer and activator of transcription 5A (Stat5a), transcription factors important for MaSC expansion. miR-141 depletion increased PR protein levels, even in cell lines where PR expression is estrogen dependent. Stat5a suppression via small interfering RNA or a small-molecule inhibitor reduced the P4-dependent increase in CK5(+) and CD44(high) cells. These data support a mechanism by which P4-triggered loss of miR-141 facilitates breast cancer cell de-differentiation through deregulation of PR and Stat5a, two transcription factors important for controlling mammary cell fate.

    Over the past four years, REAC/TS has presented a number of case reports from its Radiation Accident Registry. Victims of radiological or nuclear incidents must meet certain dose criteria for an incident to be categorized as an “accident” and be included in the registry. Although the greatest numbers of “accidents” in the United States that have been entered into the registry involve radiation devices, the greater percentage of serious accidents have involved sealed sources of one kind or another. But if one looks at the kinds of accident scenarios that have resulted in extreme consequence, i.e., death, the greater share of deaths has occurred in medical settings.

    2010-01-01

    Full Text Available Choropleth maps are commonly used in cancer reports and community discussions about cancer rates. Cancer registries increasingly use geographic information system techniques. The Centers for Disease Control and Prevention’s Division of Cancer Prevention and Control convened a Map Work Group to help guide application of geographic information system mapping techniques and to promote choropleth mapping of data from central cancer registries supported by the National Program of Cancer Registries, especially for comprehensive cancer control planning and evaluation purposes. In this 2-part series, we answer frequently asked questions about choropleth map design to display cancer incidence data. We recommend that future initiatives consider more advanced mapping, spatial analysis, and spatial statistics techniques and include usability testing with representatives of state and local programs and other cancer prevention partners.

    The International Society of Arthroplasty Registries (ISAR) Steering Committee established the Patient-Reported Outcome Measures (PROMs) Working Group to convene, evaluate, and advise on best practices in the selection, administration, and interpretation of PROMs and to support the adoption and use of PROMs for hip and knee arthroplasty in registries worldwide. The 2 main types of PROMs include generic (general health) PROMs, which provide a measure of general health for any health state, and specific PROMs, which focus on specific symptoms, diseases, organs, body regions, or body functions. The establishment of a PROM instrument requires the fulfillment of methodological standards and rigorous testing to ensure that it is valid, reliable, responsive, and acceptable to the intended population. A survey of the 41 ISAR member registries showed that 8 registries administered a PROMs program that covered all elective hip or knee arthroplasty patients and 6 registries collected PROMs for sample populations; 1 other registry had planned but had not started collection of PROMs. The most common generic instruments used were the EuroQol 5 dimension health outcome survey (EQ-5D) and the Short Form 12 health survey (SF-12) or the similar Veterans RAND 12-item health survey (VR-12). The most common specific PROMs were the Hip disability and Osteoarthritis Outcome Score (HOOS), the Knee injury and Osteoarthritis Outcome Score (KOOS), the Oxford Hip Score (OHS), the Oxford Knee Score (OKS), the Western Ontario and McMaster Universities Arthritis Index (WOMAC), and the University of California at Los Angeles Activity Score (UCLA).

    Preservation of the lower rectal sphincters has been the main concern of colorectal surgeons in an attempt to avoid colostomy. Various proposed procedures contradict the oncological principles of the operation`s radicality, especially pelvic lymphadenectomy. Prior knowledge of this space is therefore, an important factor in choosing the operative technique: radical (amputation), or conservative. The introduction of ultrasound, computed tomography and magnetic resonance imaging, have provided preoperative information about the anatomic nature of the region. The morphological and functional study supplied by lymphoscintigraphy of this space supplements the data furnished by the other imaging techniques. The objective of this prospective of this prospective study was threefold: to standardize lymphoscintigraphy, to differentiate patients with rectal cancer from those with other coloproctological diseases and to asses the lymphonodal involvement in the former by utilizing the anatomopathological and surgical correlation. The study included 60 patients with various coloproctological diseases seen on the Department of Gastroentorology, Hospital da Clinicas, University of Sao Paulo School of Medicine, from September 1990 to August 1993. Thirty were cases of rectal cancer and the remainder were other colorectal diseases. The method consisted of injecting 0.5 of a dextran solution market with radioactive technetium in the perineal region and obtaining images by a gamma camera. In the rectal cancer patients, the tracer progresses unilaterally or is absent; in the others, it is bilateral and symmetrical, although its progress may be slow. The statistical data demonstrated that in rectal cancer, lymphoscintigraphy asseses the nodal involvement approximaltely as that obtained by the sun of the anatomapathological and surgical findings. Based on the results, the following conclusioons were possible: lymphoscintigraphy is a standardized, painless and harmless test that can be

    Cancer stem cells (CSCs) have been identified in various types of cancer; however, the mechanisms by which cells acquire CSC properties such as drug resistance and tumour seeding ability are not fully understood. Here, we identified microRNA-27b (miR-27b) as a key regulator for the generation of a side-population in breast cancer cells that showed CSC properties, and also found that the anti-type II diabetes (T2D) drug metformin reduced this side-population via miR-27b-mediated repression of ectonucleotide pyrophosphatase/phosphodiesterase family member 1 (ENPP1), which is involved in T2D development. ENPP1 induced the generation of the side-population via upregulation of the ABCG2 transporter. ENPP1 was also identified as a substrate of the 26S proteasome, the activity of which is downregulated in CSCs. Overall, these results demonstrate that a T2D-associated gene plays an important role in tumour development and that its expression is strictly controlled at the mRNA and protein levels.

    Full Text Available Mung bean has been reported to have antioxidant, cytotoxic, and immunomodulatory effects in vitro. Fermented products are reported to have enhanced immunomodulation and cancer chemopreventive effects. In this study, fermented mung bean treatments in vivo were studied by monitoring tumor development, spleen immunity, serum cytokine (interleukin 2 and interferon gamma levels, and spleen/tumor antioxidant levels after injection with low and high risk 4T1 breast cancer cells. Pretreatment with fermented mung bean was associated with delayed tumor formation in low risk mice. Furthermore, this treatment was connected with higher serum anticancer cytokine levels, spleen T cell populations, splenocyte cytotoxicity, and spleen/tumor antioxidant levels. Histopathological evaluation of fermented mung bean treated tumor revealed lower event of mitotic division. On the other hand, antioxidant and nitric oxide levels that were significantly increased in the untreated mice were inhibited in the fermented mung bean treated groups. These results suggested that fermented mung bean has potential cancer chemoprevention effects through the stimulation of immunity, lipid peroxidation, and anti-inflammation.

    Full Text Available Some of the most practical questions of perinatal medicine are regarding couples who have had pregnancy problems in the past, and their risk of having such problems in future pregnancies. For example, if a couple has a child with a birth defect, what are their chances that their next child will have a defect? The key to answering such questions is the availability of linked data such as those provided by the Medical Birth Registry of Norway. Such linked data provide a unique resource for addressing a broad range of questions in perinatal epidemiology. The Medical Birth Registry of Norway has been a pioneer in answering such questions.
