    Despite available demographic data on the factors that contribute to breast cancer mortality in large population datasets, local patterns are often overlooked. Such local information could provide a valuable metric by which regional community health resources can be allocated to reduce breast cancer mortality. We used national and statewide datasets to assess geographical distribution of breast cancer mortality rates and known risk factors influencing breast cancer mortality in middle Tenness...

    Full Text Available Prostate cancer (CaP is the leading cancer among men of African descent in the USA, Caribbean, and Sub-Saharan Africa (SSA. The estimated number of CaP deaths in SSA during 2008 was more than five times that among African Americans and is expected to double in Africa by 2030. We summarize publicly available CaP data and collected data from the men of African descent and Carcinoma of the Prostate (MADCaP Consortium and the African Caribbean Cancer Consortium (AC3 to evaluate CaP incidence and mortality in men of African descent worldwide. CaP incidence and mortality are highest in men of African descent in the USA and the Caribbean. Tumor stage and grade were highest in SSA. We report a higher proportion of T1 stage prostate tumors in countries with greater percent gross domestic product spent on health care and physicians per 100,000 persons. We also observed that regions with a higher proportion of advanced tumors reported lower mortality rates. This finding suggests that CaP is underdiagnosed and/or underreported in SSA men. Nonetheless, CaP incidence and mortality represent a significant public health problem in men of African descent around the world.

    We used male pattern baldness as a proxy for long-term androgen exposure and investigated the association of dermatologist-assessed hair loss with prostate cancer-specific mortality in the first National Health and Nutrition Examination Survey Epidemiologic Follow-up Study. From the baseline survey (1971-1974), we included 4,316 men who were 25-74 years of age and had no prior cancer diagnosis. We estimated hazard ratios and used Cox proportional hazards regressions with age as the time metric and baseline hazard stratified by baseline age. A hybrid framework was used to account for stratification and clustering of the sample design, with adjustment for the variables used to calculate sample weights. During follow-up (median, 21 years), 3,284 deaths occurred; prostate cancer was the underlying cause of 107. In multivariable models, compared with no balding, any baldness was associated with a 56% higher risk of fatal prostate cancer (hazard ratio = 1.56; 95% confidence interval: 1.02, 2.37), and moderate balding specifically was associated with an 83% higher risk (hazard ratio = 1.83; 95% confidence interval: 1.15, 2.92). Conversely, patterned hair loss was not statistically significantly associated with all-cause mortality. Our analysis suggests that patterned hair loss is associated with a higher risk of fatal prostate cancer and supports the hypothesis of overlapping pathophysiological mechanisms. PMID:26764224

    OBJECTIVES: When estimating the decline in breast cancer mortality attributable to screening, the challenge is to provide valid comparison groups and to distinguish the screening effect from other effects. In Funen, Denmark, multidisciplinary breast cancer management teams started before screening...... was introduced; both activities came later in the rest of Denmark. Because Denmark had national protocols for breast cancer treatment, but hardly any opportunistic screening, Funen formed a "natural experiment", providing valid comparison groups and enabling the separation of the effect of screening...... from other factors. METHODS: Using Poisson regression we compared the observed breast cancer mortality rate in Funen after implementation of screening with the expected rate without screening. The latter was estimated from breast cancer mortality in the rest of Denmark controlled for historical...

    Mortality among people with developmental disabilities was reviewed using recent data obtained from the California Department of Developmental Services. The time interval for this report was 1991-1995. We defined two study cohorts: one beginning in January 1991 and a second in April 1993. The latter period represented the years of implementation of the Coffelt settlement. Our primary interest was in the Coffelt period cohort. Statistically significant association with increased rates of mortality was found for community residence. A trend of declining mortality was noted for the community facilities from 1991-1995, but not for the developmental centers. PMID:9803127

    With growing concerns about the impact of selective harvesting on natural populations, researchers encourage managers to implement harvest regimes that avoid or minimize the potential for demographic and evolutionary side effects. A seemingly intuitive recommendation is to implement harvest regimes that mimic natural mortality patterns. Using stochastic simulations based on a model of risk as a logistic function of a normally distributed biological trait variable, we evaluate the validity of ...

  18. Recent trends in cancer mortality in Uruguay

    International Nuclear Information System (INIS)

    Objective: To analyze trends in cancer mortality in Uruguay in the period 1989-2008. Methodology: The National Cancer Registry (NCR) collects information from cancer mortality from the death certificates: 147 631 deaths were identified in the period from cancer, which was recorded topography, sex and age. They were calculated for each year mortality rates adjusted for age (TMAE) using as standard the world population. Trends were assessed using the method and calculated the joinpoint Estimated Annual Percent Change (ESPP). Results: The TMAE presents downward trend in both sexes (ESPP = significant -0.60 in men and -0.49 In women). In the period studied, mortality presented decreasing trend when it comes to cancer breast cancer in women (ESPP -0.79, significant), and increased for prostate cancer (ESPP = 0.70) and kidney (ESPP = 1.82 and 1.71 in men and women respectively). As regards the digestive system decreased mortality observed for esophageal cancer (ESPP in = -1.93 men and women = -1.78) and stomach (ESPP = -2.22 men and women -2.24 ). Mortality for cancer of colorectum is stable in men (ESPP = 0.35 No significant (NS)) and shows a decline slight but steady in women (ESPP -0.5). As for cancers that show strong association with smoking, decreased mortality observed lung and laryngeal cancer in men (ESPP = -1.11 and -2.05 respectively), confirming the trend found between 1990 and 2001; in women there is increased mortality from lung cancer (ESPP = 2.76) that is not accompanied by increased mortality from laryngeal cancer (-0.1 ESPP = NS). Mortality from cancers oral cavity and pharynx is stable, but in women a significant increase (ESPP = 1.84) is observed when the oral cavity is analyzed in isolation (lip, tongue, gums, palate). As cervical cancer, mortality trends in 20 years is to increase (ESPP = 1.14), however, if consider only the past decade, mortality appears stabilized (ESPP = 0.57 NS). Conclusions: The overall trend of cancer mortality (all sites

    Liver Cancer has been a leading cause of death in Thailand. The purpose of this study was to model and forecast liver cancer mortality rate in Thailand using death certificate reports. A retrospective analysis of the liver cancer mortality rate was conducted. Numbering of 123,280 liver cancer causes of death cases were obtained from the national vital registration database for the 10-year period from 2000 to 2009, provided by the Ministry of Interior and coded as cause-of-death using ICD-10 by the Ministry of Public Health. Multivariate regression model was used for modeling and forecasting age-specific liver cancer mortality rates in Thailand. Liver cancer mortality increased with increasing age for each sex and was also higher in the North East provinces. The trends of liver cancer mortality remained stable in most age groups with increases during ten-year period (2000 to 2009) in the Northern and Southern. Liver cancer mortality was higher in males and increase with increasing age. There is need of liver cancer control measures to remain on a sustained and long-term basis for the high liver cancer burden rate of Thailand.

  1. Ovarian cancer mortality and industrial pollution

    International Nuclear Information System (INIS)

    We investigated whether there might be excess ovarian cancer mortality among women residing near Spanish industries, according to different categories of industrial groups and toxic substances. An ecologic study was designed to examine ovarian cancer mortality at a municipal level (period 1997–2006). Population exposure to pollution was estimated by means of distance from town to facility. Using Poisson regression models, we assessed the relative risk of dying from ovarian cancer in zones around installations, and analyzed the effect of industrial groups and pollutant substances. Excess ovarian cancer mortality was detected in the vicinity of all sectors combined, and, principally, near refineries, fertilizers plants, glass production, paper production, food/beverage sector, waste treatment plants, pharmaceutical industry and ceramic. Insofar as substances were concerned, statistically significant associations were observed for installations releasing metals and polycyclic aromatic chemicals. These results support that residing near industries could be a risk factor for ovarian cancer mortality. - Highlights: • We studied excess mortality due to ovarian cancer near Spanish industries. • Integrated nested Laplace approximations were used as a Bayesian inference tool. • We found excess ovarian cancer mortality near all industrial groups as a whole. • Risk also was found in towns near industries releasing carcinogens and metals. • Risk was associated with plants releasing polycyclic aromatic chemicals and POPs. - Our results support that residing in the vicinity of pollutant industries could be a risk factor for ovarian cancer mortality

    The National Center for Health Statistics, CDC, has produced an Atlas of United States Mortality which includes maps of rates for the leading causes of death in the United States for the period 1988-1992. As part of this project, many aspects of statistical mapping have been re-examined to maximize the atlas's effectiveness in conveying accurate mortality patterns to epidemiologists and public health practitioners. Because recent cognitive research demonstrated that no one map style is optimal for answering many different map questions, maps and graphs of several different mortality statistics are included for each cause of death. New mixed effects models were developed to provide predicted rates and improved variance estimates. Results from these models were smoothed using a weighted head-banging algorithm to produce maps of general spatial trends free of background noise. Maps of White female lung cancer rates from the new atlas are presented here to illustrate how this innovative combination of maps and graphs permits greater exploration of the underlying mortality data than is possible from previous single-map atlas designs. Published in 1999 by John Wiley & Sons, Ltd. This article is a U.S. Government work and is in the public domain in the United States. PMID:10602146

    AIM: To examine the regional variations in mortality rates of pancreatic cancer in China.METHODS: Aggregated mortality data of pancreatic cancer were extracted from the 1990-1992 national death of all causes and its mortality survey in China. Age specific and standardized mortality rates were calculated at both national and provincial levels with selected characteristics including sex and residence status.RESULTS: Mortality of pancreatic cancer ranked the ninth and accounted for 1.38 percent of the total malignancy deaths. The crude and age standardized mortality rates of pancreatic cancer in China in the period of 1990-1992 were 1.48/100 000 and 1.30/100 000, respectively. Substantial regional variations in mortality rates across China were observed with adjusted mortality rates ranging from 0.43/100 000 to 3.70/100 000 with an extremal value of 8.7.Urban residents had significant higher pancreatic mortality than rural residents.CONCLUSION: The findings of this study show different mortality rates of this disease and highlight the importance of further investigation on factors, which might contribute to the observed epidemiological patterns.

  9. Low dose irradiation reduces cancer mortality rates

    International Nuclear Information System (INIS)

    Low doses of ionizing radiation stimulate development, growth, memory, sensual acuity, fecundity, and immunity (Luckey, T.D., ''Radiation Hormesis'', CRC Press, 1991). Increased immune competence reduces cancer mortality rates and provides increased average lifespan in animals. Decreased cancer mortality rates in atom bomb victims who received low dose irradiation makes it desirable to examine populations exposed to low dose irradiation. Studies with over 300,000 workers and 7 million person-years provide a valid comparison of radiation exposed and control unclear workers (Luckey, T.D., Nurture with Ionizing Radiation, Nutrition and Cancer, 34:1-11, 1999). Careful selection of controls eliminated any ''healthy worker effect''. The person-year corrected average indicated the cancer mortality rate of exposed workers was only 51% that of control workers. Lung cancer mortality rates showed a highly significant negative correlation with radon concentrations in 272,000 U.S. homes (Cohen, B.L., Health Physics 68:157-174, 1995). In contrast, radon concentrations showed no effect on lung cancer rates in miners from different countries (Lubin, J.H. Am. J. Epidemiology 140:323-332, 1994). This provides evidence that excessive lung cancer in miners is caused by particulates (the major factor) or toxic gases. The relative risk for cancer mortality was 3.7% in 10,000 Taiwanese exposed to low level of radiation from 60Co in their steel supported homes (Luan, Y.C. et al., Am. Nuclear Soc. Trans. Boston, 1999). This remarkable finding needs further study. A major mechanism for reduced cancer mortality rates is increased immune competence; this includes both cell and humoral components. Low dose irradiation increases circulating lymphocytes. Macrophage and ''natural killer'' cells can destroy altered (cancer) cells before the mass becomes too large. Low dose irradiation also kills suppressor T-cells; this allows helper T-cells to activate killer cells and antibody producing cells

    Low doses of ionizing radiation stimulate development, growth, memory, sensual acuity, fecundity, and immunity (Luckey, T.D., ''Radiation Hormesis'', CRC Press, 1991). Increased immune competence reduces cancer mortality rates and provides increased average lifespan in animals. Decreased cancer mortality rates in atom bomb victims who received low dose irradiation makes it desirable to examine populations exposed to low dose irradiation. Studies with over 300,000 workers and 7 million person-years provide a valid comparison of radiation exposed and control unclear workers (Luckey, T.D., Nurture with Ionizing Radiation, Nutrition and Cancer, 34:1-11, 1999). Careful selection of controls eliminated any ''healthy worker effect''. The person-year corrected average indicated the cancer mortality rate of exposed workers was only 51% that of control workers. Lung cancer mortality rates showed a highly significant negative correlation with radon concentrations in 272,000 U.S. homes (Cohen, B.L., Health Physics 68:157-174, 1995). In contrast, radon concentrations showed no effect on hlumg cancer rates in miners from different countries (Lubin, J.H. Am. J. Epidemiology 140:323-332, 1994). This provides evidence that excessive lung cancer in miners is caused by particulates (the major factor) or toxic gases. The relative risk for cancer mortality was 3.7% in 10,000 Taiwanese exposed to low level of radiation from {sup 60}Co in their steel supported homes (Luan, Y.C. et al., Am. Nuclear Soc. Trans. Boston, 1999). This remarkable finding needs further study. A major mechanism for reduced cancer mortality rates is increased immune competence; this includes both cell and humoral components. Low dose irradiation increases circulating lymphocytes. Macrophage and ''natural killer'' cells can destroy altered (cancer) cells before the mass becomes too large. Low dose irradiation also kills suppressor T-cells; this allows

  13. Cancer mortality in Hiroshima and Nagasaki

    International Nuclear Information System (INIS)

    The now completed dosimetry revision as well as continued medical monitoring of the A-bomb survivors of Hiroshima and Nagasaki have led to a change in conclusions drawn in regard to cancer mortality. A major result of the dosimetry revision is that neutron doses have been much lower than previously assumed. Preston and Pierce (1987) have made cancer mortality risk estimates on the basis of the new dosimetry system. Concerning the accumulated occurrence of solid tumors, the main result is that the new dosimetry system brings relatively little change. As to leukemia induction, new reduced dose estimates lead to risk estimates that are by a factor of 2 above those made with the former dosimetry system. (orig./MG)

  19. Ionizing radiation decreases human cancer mortality rates

    International Nuclear Information System (INIS)

    Information from nine studies with exposed nuclear workers and military observers of atmospheric bomb explosions confirms the results from animal studies which showed that low doses of ionizing radiation are beneficial. The usual ''healthy worker effect'' was eliminated by using carefully selected control populations. The results from 13 million person-years show the cancer mortality rate of exposed persons is only 65.6% that of carefully selected unexposed controls. This overwhelming evidence makes it politically untenable and morally wrong to withhold public health benefits of low dose irradiation. Safe supplementation of ionizing radiation should become a public health service. (author)

Um estudo ecológico foi realizado com o objetivo de identificar possíveis associações entre padrões de consumo alimentar e taxas de mortalidade padronizadas por idade em capitais brasileiras selecionadas. O padrão de consumo alimentar em cada capital foi caracterizado com base no consumo de grupos de alimentos associados a essa neoplasia na literatura. Os dados de consumo de alimentos foram obtidos no ENDEF (Estudo Nacional de Despesas Familiares. A regressão linear múltipla foi utilizada para analisar as correlações entre as taxas de mortalidade e as variáveis alimentares. Essas taxas mostraram uma correlação positiva com o consumo de calorias, cereais, carnes, ovos/leite e legumes/frutas. Quando ajustado por consumo calórico total, carne e legumes/frutas foram as únicas variáveis que mantiveram uma correlação positiva. O modelo multivariado final com essas variáveis foi capaz de explicar 92% da variação das taxas de mortalidade nas capitais selecionadas. Esses resultados sugerem que diferenças no consumo calórico total e no consumo de carne e legumes/frutas poderiam explicar, parcialmente, os diferentes padrões de distribuição da mortalidade por câncer de cólon e reto no Brasil.Mortality rates for colorectal cancer show regional variations in Brazil, and the heterogeneous dietary profile observed in its geographic regions could possibly explain, at least partially, these different patterns.

    Full Text Available OBJECTIVE To analyze cervical and breast cancer mortality in Brazil according to socioeconomic and welfare indicators. METHODS Data on breast and cervical cancer mortality covering a 30-year period (1980-2010 were analyzed. The data were obtained from the National Mortality Database, population data from the Brazilian Institute of Geography and Statistics database, and socioeconomic and welfare information from the Institute of Applied Economic Research. Moving averages were calculated, disaggregated by capital city and municipality. The annual percent change in mortality rates was estimated by segmented linear regression using the joinpoint method. Pearson’s correlation coefficients were conducted between average mortality rate at the end of the three-year period and selected indicators in the state capital and each Brazilian state. RESULTS There was a decline in cervical cancer mortality rates throughout the period studied, except in municipalities outside of the capitals in the North and Northeast. There was a decrease in breast cancer mortality in the capitals from the end of the 1990s onwards. Favorable socioeconomic indicators were inversely correlated with cervical cancer mortality. A strong direct correlation was found with favorable indicators and an inverse correlation with fertility rate and breast cancer mortality in inner cities. CONCLUSIONS There is an ongoing dynamic process of increased risk of cervical and breast cancer and attenuation of mortality because of increased, albeit unequal, access to and provision of screening, diagnosis and treatment.

    2008-01-01

    Background The aim of this study was to describe and to compare the cancer mortality rates in urban and rural residents in Lithuania. Methods Cancer mortality has been studied using the materials of the Lithuanian cancer registry. For the period 1993–2004 age-standardized urban and rural population mortality rates (World standard) were calculated for all malignant neoplasm's and for stomach, colorectal, lung, prostate, breast and cervical cancers. The annual percentage change (APC) was calculated using log-linear regression model, two-sided Mantel-Haenzel test was used to evaluate differences in cancer mortality among rural and urban populations. Results For males in rural population cancer mortality was higher than in urban (212.2 and 197.0 cases per 100000) and for females cancer mortality was higher in urban population (103.5 and 94.2 cases per 100000, p < 0.05). During the study period the age-standardized mortality rates decreased in both sexes in urban residents. The decreasing mortality trend in urban population was contributed by decline of the rates of lung and stomach cancer in male and breast, stomach and colorectal cancer in female. Mortality rates in both urban and rural population were increasing for prostate and cervical cancers. Conclusion This study shows that large rural and urban inequalities in cancer mortality exist in Lithuania. The contrast between the health of residents in urban and rural areas invites researchers for research projects to develop, implement, and enhance cancer prevention and early detection intervention strategies for rural populations.

  9. Calculated lung cancer mortality due to radon

    International Nuclear Information System (INIS)

    From studies of miners, it is clear that an exposure to high concentrations of radon daughters leads to an increased incidence of lung cancer. In this Chapter the authors discuss how the experience for miners is used to estimate the incidence of radon-induced lung cancer among the general population. Such estimates cannot be very precise, in part because the miners studies do not lead to a well-determined relationship between the rate of cancer induction and the exposure levels. In particular, there are disparities in the results of studies for different groups of miners. These disparities may arise from the difficulties in obtaining accurate crucial data, such as the year-by-year exposure history over the working lifetime of the individual miners. Other differences may arise from differences in the smoking patterns in different groups and in details of the handling of the data. In any event, there remain substantial uncertainties in the conclusions for the miners themselves, both as to the ''average'' rate of cancer induction per WLM and as to the variation of this rate with the magnitude of the total exposure. Further, there are problems in using results obtained for miners at relatively high radon exposure levels for the prediction of the effects of radon at the much lower levels encountered in the normal indoor environment. Here one faces the problem of extrapolating from large dose levels to small dose levels. The generally adopted solution is to assume linearity

  12. The influence of death-certificate errors on cancer mortality trends

    International Nuclear Information System (INIS)

    Over the past few years, several reports have suggested a recent increase in cancer mortality based on death-certificate diagnoses. To explore the effect of death-certificate errors on temporal trends in cancer mortality rates, we analyzed the data from the Atomic Bomb Casualty Commission/Radiation Effects Research Foundation's autopsy program in Hiroshima and Nagasaki. This series includes 5886 autopsies conducted between 1961 and 1987. Our analyses were focused on lymphoma, cancer of the breast, neoplasms of the brain, multiple myeloma, and melanoma (172 cases, total) because of concern over reports of their increased mortality. These 172 autopsy cases were referred to as Cancers of Interest. A significant increase in detection rates was observed for these Cancers of Interest primarily due to a large rise in mortality between 1976 and 1987. For the remaining cancers excluding stomach and lung (defined as Other), the pattern was similar to that seen for Cancers of Interest, but the fluctuation over time was not statistically significant. Confirmation rates generally increased with time except for Cancers of Interest. As a measure of bias in mortality rates due to death-certification errors and as a method to quantify under- or overestimation of death-certificate-based mortality rates,an adjustment factor (confirmation rate divided by detection rate) was calculated. The higher the adjustment factor, the greater the need to compensate for underreporting. For Cancers of Interest the adjustment factor decreased dramatically over time, but it did not change significantly for Other cancers. When the adjustment factors for Cancers of Interest and Other were compared, a statistically significant difference was found. For Cancers of Interest, a significant interaction between type of cancer and period was seen. Our findings indicate that considerable care must be shown when interpreting temporal trends in cancer vital statistics. (author)

    Liver cancer is a common malignant tumor in China and a major health concern. We aimed to estimate the liver cancer incidence and mortality in China in 2010 using liver cancer data from some Chinese cancer registries and provide reference for liver cancer prevention and treatment. We col ected and evaluated the incidence and mortality data of liver cancer in 2010 from 145 cancer registries, which were included in the 2013 Chinese Cancer Registry Annual Report, calculated crude, standardized, and truncated incidences and mortalities, and estimated new liver cancer cases and deaths from liver cancer throughout China and in different regions in 2010 from Chinese practical population. The estimates of new liver cancer cases and deaths were 358,840 and 312,432, respectively, in China in 2010. The crude incidence, age-standardized rate by Chinese standard population (ASR China), and age-standardized rate by world standard population (ASR world) were 27.29/100,000, 21.35/100,000, and 20.87/100,000, respectively;the crude, ASR China, and ASR world mortalities were 23.76/100,000, 18.43/100,000, and 18.04/100,000, respectively. The incidence and mortality were the highest in western regions, higher in rural areas than in urban areas, and higher in males than in females. The age-specific incidence and mortality of liver cancer showed a rapid increase from age 30 and peaked at age 80-84 or 85+. Our results indicated that the 2010 incidence and mortality of liver cancer in China, especial y in undeveloped rural areas and western regions, were among high levels worldwide. The strategy for liver cancer prevention and treatment should be strengthened.

In USA, there are more than 30.000 new cases every year. We can find many risk factors of oral cancer in our daily living. Moreover, it’s easy to find the main risk factors in our society, they are smoking, alcohol consumption, tobacco consumtion, viral infection, and bad oral hygiene. For the early stadium, Five-years survival rate is about 82% and 61% for all stadium. But, more than 50% of oral cancer has been distributed (metastatic regionally and also into the other organ far away from the oral itself when it’s detected. It will decrease 5-years survival rate to be less than 50%. So that, it’s really important to detect the oral cancer at the earlier stadium. Screening is the way to find the earlier stadium. Screening is done by some methods, start from the anamnesis, physical examination, toluidine blue staining, endoscopy, cytology, telomerase examination, and also PET-scan if it’s possible (because of the financial reasons. /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin; mso-bidi-font-family:"Times New Roman"; mso-bidi-theme-font:minor-bidi;}

  16. Calculation of background lifetime risk of cancer mortality in Japan

    International Nuclear Information System (INIS)

    This study was designed to calculate the background lifetime risk of cancer mortality in Japan. The mortality and population data obtained from national surveys for the vital statistics and population census in 2010 are stratified at 5-year age intervals of 0-4, 5-9, ..., 80-84, with a final open interval of 85+ for use in a life table. It was found that the gender-averaged background lifetime risk of cancer mortality ranges from 23.7% to 28.3% among 47 prefectures, and the arithmetic mean was calculated to be 25.4%. It is important to consider the incremental risk of cancer mortality posed by exposure to ionizing radiation (e.g., an additive lifetime risk of 0.5% at the effective dose of 100 mSv) in the context of the level of the background lifetime risk of cancer mortality of the exposed population.

  17. Bayesian spatio-temporal modelling of tobacco-related cancer mortality in Switzerland

    2013-05-01

    Full Text Available Tobacco smoking is a main cause of disease in Switzerland; lung cancer being the most common cancer mortality in men and the second most common in women. Although disease-specific mortality is decreasing in men, it is steadily increasing in women. The four language regions in this country might play a role in this context as they are influenced in different ways by the cultural and social behaviour of neighbouring countries. Bayesian hierarchical spatio-temporal, negative binomial models were fitted on subgroup-specific death rates indirectly standardized by national references to explore age- and gender-specific spatio-temporal patterns of mortality due to lung cancer and other tobacco-related cancers in Switzerland for the time period 1969-2002. Differences influenced by linguistic region and life in rural or urban areas were also accounted for. Male lung cancer mortality was found to be rather homogeneous in space, whereas women were confirmed to be more affected in urban regions. Compared to the German-speaking part, female mortality was higher in the French-speaking part of the country, a result contradicting other reports of similar comparisons between France and Germany. The spatio-temporal patterns of mortality were similar for lung cancer and other tobacco-related cancers. The estimated mortality maps can support the planning in health care services and evaluation of a national tobacco control programme. Better understanding of spatial and temporal variation of cancer of the lung and other tobacco-related cancers may help in allocating resources for more effective screening, diagnosis and therapy. The methodology can be applied to similar studies in other settings.

    Using Norwegian cancer registry data we study twin and non-twin siblings to decompose variation in cancer at most common sites and cancer mortality into a genetic, shared environment and individual (unshared environmental) component. Regardless the source of sibling variation, our findings indicate that genes dominate over shared environment in explaining relatively more of the variation in cancer at most common cancer sites (but lung and skin cancer) and cancer mortality. The vast majority o...

    Predicting cancer mortality is important to estimate the needs of cancer-related services and to prevent cancer. Despite its significance, a long-term future projection of cancer mortality has not been conducted; therefore, our objective was to estimate future cancer mortality in Korea by cancer site through 2032. The specially designed Nordpred software was used to estimate cancer mortality. The cancer death data from 1983 to 2012 and the population projection data from 1983 to 2032 were obtained from the Korean National Statistics Office. Based on our analysis, age-standardized rates with the world standard population of all cancer deaths were estimated to decline from 2008-2012 to 2028-2032 (men: -39.8%, women: -33.1%). However, the crude rates are predicted to rise (men: 29.8%, women: 24.4%), and the overall number of the cancer deaths is also estimated to increase (men: 35.5%, women: 32.3%). Several cancer deaths are projected to increase (lung, liver and gallbladder, colon and rectum, pancreas and leukemia in both sexes; prostate cancer in men; and breast and ovarian cancer in women), whereas other cancer deaths are expected to decrease (stomach, esophagus and larynx in both sexes and cervical cancer in women). The largest contribution to increasing cancer deaths is due to the aging of the Korean population. In conclusion, a strategy for primary prevention, early detection, and early treatment to cope with the rapidly increasing death of cancer due to population aging is urgently required. PMID:27247498

    The objective of this study was to compare the mortality pattern of colorectal cancer according to the social development profile of the large Brazilian cities. This was an ecological study that used as units of analysis Brazilian municipalities that were considered to be large (i.e. over 100,000 inhabitants). The social indicators adopted were obtained from the Atlas of Human Development in Brazil. Mortality data came from the Mortality Information System (MIS), represented by codes C18, C19, and C20. For data analysis, municipalities were characterised according to the indicator profile used by multivariate classification cluster analysis. It was observed that the Southeast, South, and Midwest regions concentrated over 90% of cities in the group of more developed municipalities, while the North and Northeast regions were represented by 60% of cities in the group of less developed municipalities. The mortality pattern of colorectal cancer in both groups was different, with a higher average mortality rate from colorectal cancer for populations living in cities from the more developed group (p = 0.02). The mortality rate from this cancer was shown to be directly proportional to the Municipal Human Developlemnt Index (MHDI) and inversely proportional to the inequality indicator (p < 0.001); therefore the highest means were observed among the municipalities with better socioeconomic conditions. It is important to consider social disparities to ensure equity in healthcare policy management. PMID:26823683

    In Brazil, where the use of pesticide grows rapidly, studies that evaluate the impact of pesticide exposure on cancer incidence and mortality are very scarce. In this study, we evaluated the degree of correlation between pesticide sales in 1985 in eleven Brazilian states and cancer mortality rates during 1996-1998. Information of all cancer deaths occurred in men 30-69 years old from 1996 to 1998 were collected from National Mortality System. Single and multiple linear regression coefficients were obtained to assess the relationship between per capita sales of pesticides in 1985, specific-site cancer mortality rates (prostate, soft tissue, larynx, leukemia, lip, esophagus, lung, pancreas, bladder, liver, testis, stomach, brain, non-Hodgkin's lymphoma, and multiple myeloma) during 1996-1998, and several covariates. In addition, states were stratified into three groups according to tertiles of pesticides sales and cancer mortality rate ratios (MRR) were then calculated using first tertile as reference. Finally, a factor analysis was performed to reveal unapparent relationships between pesticide use and cancer mortality. Pesticide sales showed statistically significant correlation with the mortality rates for the cancers of prostate (r=0.69; p=0.019), soft tissue (r=0.71; p=0.015), leukemia (r=0.68; p=0.021), lip (r=0.73; p=0.010), esophagus (r=0.61; p=0.046), and pancreas (r=0.63; p=0.040). Moderate to weak correlations were observed for the cancers of larynx, lung, testis, bladder, liver, stomach, brain, and NHL and multiple myeloma. In addition, correlation between pesticide sales and specific-site cancer mortality rates was reinforced by multiple regression analysis. For all specific-sites, cancer mortality rates were significantly higher in the states of moderate (2nd tertile) and high (3rd tertile) pesticide sales, with MRR ranging from 1.11 to 5.61.

    Liver cancer is a common cancer and a leading cause of cancer deaths in China.To aid the government in establishing a control plan for this disease,we provided real-time surveillance information by analyzing liver cancer incidence and mortality in China in 2009 reported by the National Central Cancer Registry.Liver cancer incidence and cases of death were retrieved from the national database using the ICD-10 topography code "C22".Crude incidence and mortality were calculated and stratified by sex,age,and location (urban/rural).China's population in 1982 and Segi (world) population structures were used for age-standardized rates.In cancer registration areas in 2009,the crude incidence of liver cancer was 28.71/100,000,making it the fourth most common cancer in China,third most common in males,and fifth most common in females.The crude mortality of liver cancer was 26.04/100,000,making it the second leading cause of cancer death in China and urban areas and the third leading cause in rural areas.Incidence and mortality were higher in males than in females and were higher in rural areas than in urban areas.The age-specific incidence and mortality were relatively low among age groups under 30years but dramatically increased and peaked in the 80-84 years old group.These findings confirm that liver cancer is a common and fatal cancer in China.Primary and secondary prevention such as health education,hepatitis B virus vaccination,and early detection should be carried out both in males and females,in urban and rural areas.

    Full Text Available Background: The aim of this study is to verify the existence of different rates of cancer incidence and mortality in males in the urban and rural populations of Umbria and to formulate hypotheses as to why this occurs. Methods: Directly age-adjusted incidence rates (AAIR and age-adjusted death rates (AADR were calculated for 1998-2002 and the expected number of rural cases (standardized incidence ratios-SIRs and standardized mortality ratios-SMRs was determined by indirect standardization using urban incidence and mortality. Results: Urban zones have higher AAIR’s for the most common cancer sites. Significantly lower SIRs, in rural areas, were shown for skin melanoma, prostate and bladder cancers and a significantly lower SIR was also determined for the combination of all cancer sites. Lower AADRs in rural areas were demonstrated for the most common cancer sites and significant low SMRs were shown for lung cancer and skin melanoma. Prostate cancer incidence is significantly higher in urban areas whereas the mortality rate is slightly higher in rural municipalities probably due to the effects of the opportunistic screening widely available in Umbria, particularly in zones near diagnostic services. A very similar pattern was found for urinary bladder cancer; this could be related to the association between prostate and bladder cancer sites. Both incidence and mortality from melanoma are significantly lower in rural areas, this may be due to the difficulty in accessing diagnostic services or/and to different occupational exposure patterns. Conclusion: It would appear in Umbria that differences in health services utilization continue to exist. In particular, our results are compatible with a lower diffusion of preventive activities for prostate cancer and skin melanoma in rural areas.

  10. Childhood cancer mortality in relation to the St Lucie nuclear power station

    International Nuclear Information System (INIS)

    An unusual county-wide excess of childhood cancers of brain and other nervous tissue in the late 1990s in St Lucie County, Florida, prompted the Florida Department of Health to conduct a case-control study within the county assessing residential chemical exposures. No clear associations were found, but claims were then made that the release of radioactive substances such as strontium 90 from the St Lucie nuclear power station, which began operating in 1976, might have played a role. To test the plausibility of this hypothesis, we extended by 17 years a previous study of county mortality conducted by the National Cancer Institute. Rates of total cancer, leukaemia and cancer of brain and other nervous tissue in children and across all ages in St Lucie County were evaluated with respect to the years before and after the nuclear power station began operation and contrasted with rates in two similar counties in Florida (Polk and Volusia). Over the prolonged period 1950-2000, no unusual patterns of childhood cancer mortality were found for St Lucie County as a whole. In particular, no unusual patterns of childhood cancer mortality were seen in relation to the start-up of the St Lucie nuclear power station in 1976. Further, there were no significant differences in mortality between the study and comparison counties for any cancer in the time period after the power station was in operation. Relative rates for all childhood cancers and for childhood leukaemia were higher before the nuclear facility began operating than after, while rates of brain and other nervous tissue cancer were slightly lower in St Lucie County than in the two comparison counties for both time periods. Although definitive conclusions cannot be drawn from descriptive studies, these data provide no support for the hypothesis that the operation of the St Lucie nuclear power station has adversely affected the cancer mortality experience of county residents

  11. Correlation between natural radiation exposure and cancer mortality, (4)

    International Nuclear Information System (INIS)

    In the previous studies, using Pearson's product moment correlation coefficient, we found that in most cases of cancers, statistically significant positive correlations were observed between natural background radiation exposure rate and crude cancer mortality rate over the period 1950 - 1978. Furthermore, we found that the statistical significance of correlation between natural background radiation exposure rate and the age-adjusted cancer mortality rate in the same period mostly disappeared. We studied the cause of this apparent correlation and found that the prefecture with a higher natural background radiation exposure rate had a greater component ratio of older people. In Japan, a number of prefectures with a higher natural background exposure rate are located in relatively thinly populated districts which have been experiencing an outflow of the younger generation to more highly industrialized and urbanized areas. Therefore, statistically significant positive correlations were observed for almost all cancers between natural background radiation exposure rate and crude cancer mortality rate. In the present investigation, we statistically tested the frequency distributions of natural background radiation exposure rate and age-adjusted cancer mortality rate, and calculated Spearman's rank correlation coefficient between natural background radiation exposure rate and the age-adjusted cancer mortality rate. The frequency distribution of the natural background radiation exposure rate and that of the age-adjusted mortality rate appeared normal in most cases of cancer, and the statistical significance of correlation between natural background exposure rate and the age-adjusted cancer mortality rate did not differ much on the whole, even though we used Spearman's rank correlation coefficient between them.

    2006-01-01

    Gastric cancer is one of the most frequent cancers in the world; almost two-thirds of gastric cancer cases and deaths occur in less developed regions. In China,based on two national mortality surveys conducted in 1970s and 1990s, there is an obvious clustering of geographical distribution of gastric cancer in the country, with the high mortality being mostly located in rural areas, especially in Gansu, Henan, Hebei, Shanxi and Shaanxi Provinces in the middle-western part of China. Despite a slight increase from the 1970s to early 1990s, remarkable declines in gastric cancer mortality were noticed in almost the entire population during the last decade in China. These declines were largely due to the dramatic improvements in the social-economic environment, lifestyle, nutrition, education and health care system after economic reforms started two decades ago. Nevertheless, gastric cancer will remain a significant cancer burden currently and be one of the key issues in cancer prevention and control strategy in China. It was predicted that, in 2005, 0.3 million deaths and 0.4 million new cases from gastric cancer would rank the third most common cancer. The essential package of the prevention and control strategy for gastric cancer in China would focus on controlling Helicobacter pylori (H pylori) infection, improving educational levels, advocating healthy diet and anti-tobacco campaign, searching for cost-effective early detection, diagnosis and treatment programs including approaches for curable management and palliative care.

    Introduction In the United States, prostate cancer mortality rates have declined in recent decades. Cigarette smoking, a risk factor for prostate cancer death, has also declined. It is unknown whether declines in smoking prevalence produced detectable declines in prostate cancer mortality. We examined state prostate cancer mortality rates in relation to changes in cigarette smoking. Methods We studied men aged 35 years or older from California, Kentucky, Maryland, and Utah. Data on state smoking prevalence were obtained from the Behavioral Risk Factor Surveillance System. Mortality rates for prostate cancer and external causes (control condition) were obtained from the Centers for Disease Control and Prevention’s Wide-Ranging Online Data for Epidemiologic Research. The average annual percentage change from 1999 through 2010 was estimated using joinpoint analysis. Results From 1999 through 2010, smoking in California declined by 3.5% per year (−4.4% to −2.5%), and prostate cancer mortality rates declined by 2.5% per year (−2.9% to −2.2%). In Kentucky, smoking declined by 3.0% per year (−4.0% to −1.9%) and prostate cancer mortality rates declined by 3.5% per year (−4.3% to −2.7%). In Maryland, smoking declined by 3.0% per year (−7.0% to 1.2%), and prostate cancer mortality rates declined by 3.5% per year (−4.1% to −3.0%).In Utah, smoking declined by 3.5% per year (−5.6% to −1.3%) and prostate cancer mortality rates declined by 2.1% per year (−3.8% to −0.4%). No corresponding patterns were observed for external causes of death. Conclusion Declines in prostate cancer mortality rates appear to parallel declines in smoking prevalence at the population level. This study suggests that declines in prostate cancer mortality rates may be a beneficial effect of reduced smoking in the population. PMID:27079649

    To estimate the cancer incidences and mortalities in China in 2010, the National Central Cancer Registry (NCCR) of China evaluated data for the year of 2010 from 145 qualified cancer registries covering 158,403,248 people (92,433,739 in urban areas and 65,969,509 in rural areas). The estimates of new cancer cases and cancer deaths were 3,093,039 and 1,956,622 in 2010, respectively. The percentage of morphologically verified cases were 67.11%; 2.99% of incident cases were identified through death certification only, with the mortality to incidence ratio of 0.61. The crude incidence was 235.23/100,000 (268.65/100,000 in males and 200.21/100,000 in females). The age-standardized rates by Chinese standard population (ASR China) and by world standard population (ASR world) were 184.58/100,000 and 181.49/100,000, respectively, with a cumulative incidence (0-74 years old) of 21.11%. The crude cancer mortality was 148.81/100,000 (186.37/100,000 in males and 109.42/100,000 in females). The ASR China and ASR world were 113.92/100,000 and 112.86/100,000, respectively, with a cumulative mortality of 12.78%. Lung, breast, gastric, liver, esophageal, colorectal, and cervical cancers were the most common cancers. Lung, liver, gastric, esophageal, colorectal, breast, and pancreatic cancers were the leading causes of cancer deaths. The coverage of cancer registration has rapidly increased in China in recent years and may reflect more accurate cancer burdens among populations living in different areas. Given the increasing cancer burden in the past decades, China should strengthen its cancer prevention and control.

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

    Declining cancer incidence and mortality rates in the United States (U.S.) have continued through the first decade of the twenty-first century. Reductions in tobacco use, greater uptake of prevention measures, adoption of early detection methods, and improved treatments have resulted in improved outcomes for both men and women. However, Black Americans continue to have the higher cancer mortality rates and shorter survival times. This review discusses and compares the cancer mortality rates a...

  20. Mortality from lung cancer in Ontario uranium miners

    International Nuclear Information System (INIS)

    Mortality from lung cancer was greater in Ontario uranium miners than in the general male population (observed = 152, expected = 67.6, standardised mortality ratio 225, 95% confidence interval 191-264). Part of the excess of lung cancer may be because the proportion of men who are smokers or have smoked is greater in uranium miners than in Ontario men. Smoking does not explain the whole excess. The excess relative risk of lung cancer from the same degree of exposure to short lived radon progeny is greatest five to 14 years after exposure and less subsequently. It is greater in men under the age of 55 years and less in older men. Part of the excess of lung cancer mortality in Ontario uranium miners is probably also due to exposure to arsenic that occurred earlier in gold mines. (Author)

  2. Mortality patterns among a retrospective cohort of uranium mill workers

    International Nuclear Information System (INIS)

    The long-term health effects associated with the milling of uranium ore are of interest particularly because of exposures to uranium and thorium-230. Excess risks of pulmonary and lymphatic malignancies have been suggested by previous epdiemiologic studies of persons milling or smelting uranium ores, and nephrotoxic effects of uranium have been reported in both man and animals. To test these three previously reported associations and to assess all cause-specific mortality patterns among uranium mill workers, we carried out a retrospective cohort study of 2002 uranium millers employed in any of seven mills at least one year before 1972. Ninety-eight percent (98%) followup of the cohort through 1977 resulted in 533 deaths observed versus 605 expected from US White male mortality rates. Mortality from most causes was lower than expected. Significant excess risks were found only for nonmalignant respiratory disease and miscellaneous accidents but not for any of the three diseases of a priori interest. However, nonsignificant excesses were found for lymphatic malignancies after 20 years latency and for death due to chronic nephritis among short-term workers

    The epidemic of lung cancer in Xuanwei City, China, remains serious despite the reduction of the risk of indoor air pollution through citywide stove improvement. The main objective of this study was to characterize the influences of topography on the spatiotemporal variations of lung cancer mortality in Xuanwei during 1990–2013. Using the spatially empirical Bayes method, the smoothed mortality rate of lung cancer was obtained according to the mortality data and population data collected from the retrospective survey (1990–2005) and online registration data (2011–2013). Spatial variations of the village-level mortality rate and topographic factors, including the relief degree of land surface (RDLS) and dwelling conditions (VDC), were characterized through spatial autocorrelation and hotspot analysis. The relationship between topographic factors and the epidemic of lung cancer was explored using correlation analysis and geographically weighted regression (GWR). There is a pocket-like area (PLA) in Xuanwei, covering the clustered villages with lower RDLS and higher VDC. Although the villages with higher mortality rate (>80 per 105) geographically expanded from the center to the northeast of Xuanwei during 1990–2013, the village-level mortality rate was spatially clustered, which yielded a persistent hotspot area in the upward part of the PLA. In particular, the epidemic of lung cancer was closely correlated with both RDLS and VDC at the village scale, and its spatial heterogeneity could be greatly explained by the village-level VDC in the GWR model. Spatiotemporally featured lung cancer mortality in Xuanwei was potentially influenced by topographic conditions at the village scale. PMID:27164122

    ABSTRACT OBJECTIVE To describe the trend in cancer mortality rates in Brazil and regions before and after correction for underreporting of deaths and redistribution of ill-defined and nonspecific causes. METHODS The study used data of deaths from lung cancer among the population aged from 30 to 69 years, notified to the Mortality Information System between 1996 and 2011, corrected for underreporting of deaths, non-registered sex and age , and causes with ill-defined or garbage codes according to sex, age, and region. Standardized rates were calculated by age for raw and corrected data. An analysis of time trend in lung cancer mortality was carried out using the regression model with autoregressive errors. RESULTS Lung cancer in Brazil presented higher rates among men compared to women, and the South region showed the highest death risk in 1996 and 2011. Mortality showed a trend of reduction for males and increase for women. CONCLUSIONS Lung cancer in Brazil presented different distribution patterns according to sex, with higher rates among men and a reduction in the mortality trend for men and increase for women.

    Full Text Available Biological measures of aging are important for understanding the health of an aging population, with epigenetics particularly promising. Previous studies found that tumor tissue is epigenetically older than its donors are chronologically. We examined whether blood Δage (the discrepancy between epigenetic and chronological ages can predict cancer incidence or mortality, thus assessing its potential as a cancer biomarker. In a prospective cohort, Δage and its rate of change over time were calculated in 834 blood leukocyte samples collected from 442 participants free of cancer at blood draw. About 3–5 years before cancer onset or death, Δage was associated with cancer risks in a dose-responsive manner (P = 0.02 and a one-year increase in Δage was associated with cancer incidence (HR: 1.06, 95% CI: 1.02–1.10 and mortality (HR: 1.17, 95% CI: 1.07–1.28. Participants with smaller Δage and decelerated epigenetic aging over time had the lowest risks of cancer incidence (P = 0.003 and mortality (P = 0.02. Δage was associated with cancer incidence in a ‘J-shaped’ manner for subjects examined pre-2003, and with cancer mortality in a time-varying manner. We conclude that blood epigenetic age may mirror epigenetic abnormalities related to cancer development, potentially serving as a minimally invasive biomarker for cancer early detection.

    This study assessed the association between glucose-lowering drug (GLD) use, including metformin, sulphonylurea derivatives and insulin, after breast cancer diagnosis and breast cancer-specific and all-cause mortality. 1763 breast cancer patients, diagnosed between 1998 and 2010, with type 2 diabetes were included. Cancer information was retrieved from English cancer registries, prescription data from the UK Clinical Practice Research Datalink and mortality data from the Office of National Statistics (up to January 2012). Time-varying Cox regression models were used to calculate HRs and 95 % CIs for the association between GLD use and breast cancer-specific and all-cause mortality. In 1057 patients with diabetes before breast cancer, there was some evidence that breast cancer-specific mortality decreased with each year of metformin use (adjusted HR 0.88; 95 % CI 0.75-1.04), with a strong association seen with over 2 years of use (adjusted HR 0.47; 95 % CI 0.26-0.82). Sulphonylurea derivative use for less than 2 years was associated with increased breast cancer-specific mortality (adjusted HR 1.70; 95 % CI 1.18-2.46), but longer use was not (adjusted HR 0.94; 95 % CI 0.54-1.66). In 706 patients who developed diabetes after breast cancer, similar patterns were seen for metformin, but sulphonylurea derivative use was strongly associated with cancer-specific mortality (adjusted HR 3.64; 95 % CI 2.16-6.16), with similar estimates for short- and long-term users. This study provides some support for an inverse association between, mainly long-term, metformin use and (breast cancer-specific) mortality. In addition, sulphonylurea derivative use was associated with increased breast cancer-specific mortality, but this should be interpreted cautiously, as it could reflect selective prescribing in advanced cancer patients.

    Data are presented on mortality from neoplasms as determined from death certificates in a cohort of 8393 college men, according to athletic status in college. Major athletes (lettermen) died significantly more often from neoplasms than nonathletes. Mean age at death from neoplasms (underlying cause) was significantly lower in major athletes than in both minor athletes and nonathletes. After matching major athletes with nonathletes of comparable body size (height and weight), differences in proportional mortality and mean age at death from neoplasms persisted, although not statistically significant for the smaller samples. Correlation coefficients (Pearson r) and partial r's between weight in college and age at death from neoplasms were negative but of low magnitude. Some possible explanations for the differences between major athletes and nonathletes are discussed.

The aim of this study was to examine the prevalence of COPD and emphysema at the time of primary lung cancer diagnosis and to examine factors associated with survival.  Materials and methods: Medical records, pulmonary function tests, and computed tomography scans were used to determine the presence of COPD and emphysema in patients diagnosed with primary lung cancer at the University Hospital of North Norway in 2008–2010.  Results: Among the 174 lung cancer patients, 69% had COPD or emphysema (39% with COPD, 59% with emphysema; male:female ratio 101:73. Neither COPD nor emphysema were significantly associated with lung cancer mortality, whereas patients with non-small-cell lung cancer other than adenocarcinoma and squamous cell carcinoma had a risk of lung cancer mortality that was more than four times higher than that of patients with small-cell lung cancer (hazard ratio [HR] 4.19, 95% confidence interval [CI] 1.56–11.25. Females had a lower risk of lung cancer mortality than males (HR 0.63, 95% CI 0.42–0.94, and patients aged ≥75 years had a risk that was twice that of patients aged <75 years (HR 2.48, 95% CI 1.59–3.87. Low partial arterial oxygen pressure (4.0–8.4 kPa increased the risk of lung cancer mortality (HR 2.26, 95% CI 1.29–3.96. So did low partial arterial carbon dioxide pressure (3.0–4.9 kPa among stage IV lung cancer patients (HR 2.23, 95% CI 1.29–3.85.

    Jian-Bing Wang

    Full Text Available BACKGROUND: To estimate the contribution of tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake to esophageal cancer mortality and incidence in China. METHODOLOGY/PRINCIPAL FINDINGS: We calculated the proportion of esophageal cancer attributable to four known modifiable risk factors [population attributable fraction (PAF]. Exposure data was taken from meta-analyses and large-scale national surveys of representative samples of the Chinese population. Data on relative risks were also from meta-analyses and large-scale prospective studies. Esophageal cancer mortality and incidence came from the 3(rd national death cause survey and population-based cancer registries in China. We estimated that 87,065 esophageal cancer deaths (men 67,686; women: 19,379 and 108,206 cases (men: 83,968, women: 24,238 were attributable to tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake in China in 2005. About 17.9% of esophageal cancer deaths among men and 1.9% among women were attributable to tobacco smoking. About 15.2% of esophageal cancer deaths in men and 1.3% in women were caused by alcohol drinking. Low vegetable intake was responsible for 4.3% esophageal cancer deaths in men and 4.1% in women. The fraction of esophageal cancer deaths attributable to low fruit intake was 27.1% in men and 28.0% in women. Overall, 46% of esophageal cancers (51% in men and 33% in women were attributable to these four modifiable risk factors. CONCLUSIONS/SIGNIFICANCE: Tobacco smoking, alcohol drinking, low vegetable intake and low fruit intake were responsible for 46% of esophageal cancer mortality and incidence in China in 2005. These findings provide useful data for developing guidelines for esophageal cancer prevention and control in China.

  14. Cancer and non-cancer mortality risks in atomic bomb survivors, 1950-1997: lSS report 13

    International Nuclear Information System (INIS)

    The present report continues the series of general reports on mortality in the Life Span Study (LSS) cohort followed by the Radiation Effects Research Foundation (RERF). The present report deals with solid cancer and non-cancer disease mortality during the period from 1950 through 1997, updating with seven additional years of follow-up LSS Report 12. The LSS cohort includes 86,572 people with individual dose estimates. There have been 9,335 deaths from solid cancer and 31,881 deaths from non-cancer disease during the 47 years follow-up. 19% of the solid cancer and 15% of the non-cancer disease deaths occurred during the newly added follow-up period. While excess rates for radiation-associated solid cancers are seen to increase throughout the study period regardless of age at exposure, relative risks are highest for those exposed as children but appear to decline with increasing age. For those exposed at age 30 the solid cancer risk is elevated by 47% at age 70. There are interesting variations by site of age and age at exposure pattern, though the patterns of the risk do not differ statistically from those for solid cancer as a group. However, the interpretation of age at exposure effects on the ERR or the EAR is complicated by changes in background rates with birth cohort or time trend. The evidence for radiation effects on non-cancer mortality remains strong with risks increased by about 14% per Sv during the last thirty years of follow-up. Statistically significant increases are seen for heart disease, stroke, digestive diseases, and respiratory diseases. Although the non-cancer data are consistent with some non-linearity in the dose response, the evidence against linearity is weaker than past. However, there is no direct statistical evidence of radiation effects for doses less than 0.5 Sv

    1989-01-01

    An analysis of the mortality of a cohort of 6629 workers employed from 1906 to 1981 in a rubber tyre factory in northern Italy (978 deaths and over 133,000 man-years at risk) showed that the all cause mortality ratio was slightly lower than expected (0.91). Overall cancer mortality was close to expected (275 v 259.4) but there were significant excess rates for two cancer sites: pleura (9 observed v 0.8 expected, which may be due to the use of fibre containing talc) and bladder (16 observed v 8.8 expected). Death rates were not raised for other sites previously associated with employment in the rubber industry, such as cancers of the lung and brain, leukaemias, or lymphomas. The substantially reduced relative risk of pleural cancer among workers first employed after 1940 (RR = 0.05 compared with before 1940) probably reflected improvements in working conditions over more recent periods. For cancer of the bladder, the relative risk was also lower for workers first engaged after 1940. Thus no appreciable risk for any disease was apparent for workers employed over the past four decades. Analysis for each of the 27 job categories showed a substantial excess for cancer of the pleura in the mechanical maintenance workers (4 observed v 0.17 expected); an excess of cancer of the lung (21 v 13.48) was also present in this job category.

  17. Cancer mortality and radioactive fallout in southwestern Utah

    International Nuclear Information System (INIS)

    Cancer mortality was compared between a three-county region in southwestern Utah and the remainder of Utah in an investigation of reported excess cancer risks associated with residence in southwestern Utah during the period of above-ground nuclear tests at the Nevada Test Site. Because most of the fallout in southwestern Utah was deposited during 1953-1957, comparisons were limited to persons born before 1958, and deaths from leukemia and bone cancer during 1955-1980 and from other cancers during 1964-1980. There was no excess risk of cancer mortality in southwestern Utah, for single or grouped sites, with the single exception of leukemia which showed statistically significant odds ratios of 1.45 based on 62 deaths at all ages, and 2.84 based on nine deaths at ages 0-14. The finding for childhood leukemia was based on different time periods and geographic comparisons from those of two earlier studies in which no such excess was found. Mortality from all cancer sites combined was significantly lower in southwestern Utah than in the remainder of the state, even after adjustment for the higher proportion of (lower risk) Mormons in southwestern Utah. The present results, including the positive association for leukemia, are inconsistent with the high excess risks reported by Johnson (JAMA 1984;251:230-6) based on an interview survey of cancer incidence among long-term Mormon residents of southwestern Utah

  19. Studies of the mortality of A-bomb survivors. 8. Cancer mortality, 1950-1982

    International Nuclear Information System (INIS)

    This study extends an earlier one by 4 years (1979-1982) and includes mortality data on 11,393 additional Nagasaki survivors. Significant dose responses are observed for leukemia, multiple myeloma, and cancers of the lung, female breast, stomach, colon, esophagus, and urinary tract. Due to diagnostic difficulties, results for liver and ovarian cancers, while suggestive of significant dose responses, do not provide convincing evidence for radiogenic effects. No significant dose responses are seen for cancers of the gallbladder, prostate, rectum, pancreas, or uterus, or for lymphoma. For solid tumors, largely due to sex-specific differences in the background rates, the relative risk of radiation-induced mortality is greater for women than for men. For nonleukemic cancers the relative risk seen in those who were young when exposed has decreased with time, while the smaller risks for those who were older at exposure have tended to increase. While the absolute excess risks of radiation-induced mortality due to nonleukemic cancer have increased with time for all age-at-exposure groups, both excess and relative risks of leukemia have generally decreased with time. For leukemia, the rate of decrease in risk and the initial level of risk are inversely related to age at exposure

    Dietary factors were analyzed for the regional difference of GI tract cancer mortality rates in China. Sixty-five rural counties were selected among a total of 2,392 counties to represent a range of rates for seven most prevalent cancers. The dietary data in the selected 65 counties were obtained by three-day dietary record of households in 1983. The four digestive cancer mortality rates (annual cases per 100,000 standardized truncated rates for ages 35-64) and per capita food consumption were analyzed by the principal components factor analysis. Esophageal cancer associated with poor area, dietary pattern rich in starchy tubers, and salt, lack of consumption of meat, eggs, vegetables and rice. Stomach cancer seemed to be less associated with diet in this study because of its small model Kaiser-Meyer-Olkin (KMO) measure of sampling adequacy, suggesting some other carcinogenic factors would play more important role in the development of this cancer in China. The colon and rectal cancer showed close relation to diet; rich in sea vegetables, eggs, soy sauce, meat and fish, while lack in consumption of milk and dairy products. Rapeseed oil was more important risk factor for colon cancer than that of rectum. Rice, processed starch and sugar were closely associated with colon cancer, supporting the insulin/colon cancer hypothesis. PMID:10510586

    We investigated social disparities in breast cancer (BC) mortality, leveraging data from the California Breast Cancer Survivorship Consortium. The associations of race/ethnicity, education, and neighborhood SES (nSES) with all-cause and BC-specific mortality were assessed among 9372 women with BC (diagnosed 1993-2007 in California with follow-up through 2010) from four racial/ethnic groups [African American, Asian American, Latina, and non-Latina (NL) White] using Cox proportional hazards models. Compared to NL White women with high-education/high-nSES, higher all-cause mortality was observed among NL White women with high-education/low-nSES [hazard ratio (HR) (95 % confidence interval) 1.24 (1.08-1.43)], and African American women with low-nSES, regardless of education [high education HR 1.24 (1.03-1.49); low-education HR 1.19 (0.99-1.44)]. Latina women with low-education/high-nSES had lower all-cause mortality [HR 0.70 (0.54-0.90)] and non-significant lower mortality was observed for Asian American women, regardless of their education and nSES. Similar patterns were seen for BC-specific mortality. Individual- and neighborhood-level measures of SES interact with race/ethnicity to impact mortality after BC diagnosis. Considering the joint impacts of these social factors may offer insights to understanding inequalities by multiple social determinants of health. PMID:26072260

  2. Chronic liver disease related mortality pattern in northern Pakistan

    International Nuclear Information System (INIS)

    Objective: To describe the mortality pattern pertaining to chronic liver disease (CLD) in Northern Pakistan. Results: There were a total of 8529 admissions in twelve months period from August 2001 to July 2002. There were 283 (3.31%) total deaths. Out of these, 160 deaths were pertaining to medical causes. Out of these medical cases, 33 (20.6%) patients had died of chronic liver disease. Other major causes of death were cerebro-vascular accident (18.7%), malignancy (18.1%) and acute myocardial infarction (10.6%). Out of 33 patients of CLD, 12 (36%) presented with acute gastrointestinal (Gl) bleeding, 9(27%) presented with Ascites and 6(18%) presented with altered mental status due to hepatic encephalopathy. Rest of them had jaundice and fever as their initial presentation. Out of these 33 patients with CLD, 23 (70%) had hepatitis C virus (HCV) as cause of their liver disease, 4 (12%) had hepatitis B virus (HBV) infection, 3(9%) had both hepatitis B and hepatitis C virus infections and 3 (9%) had no known cause of their chronic liver disease. Conclusion: Chronic liver disease is a major cause of mortality in this part of Pakistan at a tertiary care hospital. HCV infection is the main cause of chronic liver disease followed by either HBV or a combination of these viruses. Major manifestations of CLD have been gastrointestinal bleeding, hepatic failure and portal hypertension.(author)

    1983-01-01

    The OSHA standard for coke oven emissions, which went into effect in January 1977, sets a permissible exposure limit to coke oven emissions of 150 micrograms/m3 benzene-soluble fraction of total particulate matter (BSFTPM). Review of the epidemiologic evidence for the standard indicates an excess relative risk for lung cancer as high as 16-fold in topside coke oven workers with 15 years of exposure or more. There is also evidence for a consistent dose-response relationship in lung cancer mort...

    Worldwide data on terrorist incidents between 1968 and 2004 gathered by the RAND corporation and the Oklahoma City National Memorial Institute for the Prevention of Terrorism (MIPT) were assessed for patterns and trends in morbidity/mortality. The data involve a total of 19,828 events, 7,401 ''adverse'' events (each causing {ge}1 victim), 91,346 cases of casualty (either injury or death) and 25,408 deaths. Analyses revealed a number of interesting patterns and apparently significant trends. Most terror-related adverse events, casualties and deaths involved bombs and guns. Weapon-specific patterns and terror-related risk levels in Israel (ISR) have differed markedly from those of all other regions combined (AOR). ISR had a fatal fraction of casualties about half that of AOR, but has experienced relatively constant lifetime terror-related casualty risks on the order of 0.5%--a level 2 to 3 orders of magnitude more than those experienced in AOR, which have increased {approx}100-fold over the same period. Individual event fatality has increased steadily, the median increasing from 14 to 50%. Lorenz curves obtained indicate substantial dispersion among victim/event rates: about half of all victims were caused by the top 2% (10%) of harm-ranked events in OAR (ISR). Extreme values of victim/event rates were found to be well modeled by classic or generalized Pareto distributions, indicating that these rates have been as predictable as similarly extreme phenomena such as rainfall, sea levels, earthquakes, etc. This observation suggests that these extreme-value patterns may be used to improve strategies to prevent and manage risks associated with terror-related consequences.

    Full Text Available Data about mortality from malignant tumors of endometrium were analyzed in the Belgrade area during the period 1975-2000. The obtained results showed that the average percentage of endometrial cancer in mortality structure from all the cancers of female population was 2.65%. During the observed 26-years period, malignant tumors of endometrium constituted 17.38% of all the tumors of gynecological localization. The standardized mortality rate in 1975 (population worldwide used as a standard 7.06/100 000 population while in 2000 it was 1.78/100 000 population, respectively, which showed almost fourfold mortality decline during the observed period (y=4.72-0.16x. A trend of declining risk of dying from endometrial cancer was present in all the age groups. The obtained results indicated that in the observed period the average mortality rates ranged from 0.14/100 000 population in females aged up to 34 years (y=0.30-0.01x, and reached the highest value in females aged 65-74 years (14.57/100 000; y=23.43-0.66x, and 75 years of age and over (19.62/100 000; y=31.17-0.85x.

    1982-02-01

    An epidemiological and environmental study of rock and slag mineral wool production workers was undertaken at a plant that has been in operation since the early 1900s. Size characteristics of fibres produced by each process at the plant and data from industrial hygiene surveys were used to evaluate current and past exposures. These data suggest that the average historical airborne fibre concentration probably did not exceed 2.5 fibres/cc before 1935 and 1.0 fibre/cc after 1935. A retrospective cohort mortality study was designed to assess mortality patterns. Detailed occupational histories were compiled on all plant employees. All jobs in the plant were assigned to one of eight potential exposure categories to assess the extent and severity of mineral wool exposure and the effect of other significant exposures on employee mortality. Findings included an increase in the number of deaths due to cancer of the digestive system and non-malignant respiratory disease among workers who had over 20 years' exposure to mineral wool or who had survived 20 years since their first exposure to mineral wool. These findings are not inconsistent with those of Enterline's (Symposium on Biological Effects of Mineral Fibres, Lyon, France, September 1979) in the Thermal Insulation Manufacturers' Association's mortality study of men employed in four mineral wool plants.

    AIM: To describe the mortality rate of pancreatic cancer and its distribution in China during the period of 1991-2000.METHODS: Based on the data of demography and death collected through China′s Disease Surveillance Point System (DSPS) over the period of 1991-2000, the distribution of death rate of pancreatic cancer was described in terms of age group, gender, calendar year, rural/urban residence and administrative district.RESULTS: A total of 1 619 death cases attributed to pancreatic cancer (975 men and 644 women) were reported by DSPS during 1991-2000. The reported, adjusted and agestandardized mortality rates increased from 1.46, 1.75, and 2.18 per 100 000 populations in 1991 to 2.38, 3.06, and 3.26per 100 000 populations in 2000. The majority (69.62 %) of the deaths of pancreatic cancer were seen in the age group of 60 years and older. The mortality rate was higher in men than in women, but the male to female death rate ratios decreased during the 10 years. Our data also showed that the death rate of pancreatic cancer in urban areas was about 2-4 fold higher than that in rural areas, and in Northeast and East China, the death rates were higher than those in the other 5 administrative districts.CONCLUSION: The death rate due to pancreatic cancer was rising during the period of 1991-2000 and the peak mortality of pancreatic cancer might arrive in China.

  9. Breast cancer incidence and mortality in the Canadian fluoroscopy study

    International Nuclear Information System (INIS)

    This report describes the formation of the National Cancer Incidence Reporting System in a data base format suitable for computerized record linkage, and the linkage of the data from the Canadian study of cancer following multiple fluoroscopies to that database and to the Canadian National Mortality Data Base between 1940 and 1987. A comprehensive statistical analysis of the breast cancer mortality data occurring among female members of the cohort between 1950 and 1987 with respect to exposure to low-LET radiation is reported, together with a parallel analysis of the breast cancer incidence data between 1975 and 1983. The Canadian fluoroscopy study is a cohort study of tuberculosis patients first treated in Canadian institutions between 1930 and 1952. The present mortality analysis relates to the breast cancer mortality experience between 1950 and 1987. A total of 677 deaths from breast cancer was observed in this period. The most appropriate dose-response relationship appears to be a simple linear one. There is a strong modifying influence of age at first exposure; women first exposed past the age of 30 have little excess risk due to radiation exposure. The breast cancer incidence analysis is based upon 628 cases observed between 1975 and 1983. Again a simple linear model appears to provide an adequate fit to the data. There is a suggestion of time dependency under the additive model, but this is not statistically significant. The results from this latest analysis continue to be reassuring in terms of radiation risk from mammography. (L.L.) 15 refs., figs., tabs

  10. Municipal distribution of bladder cancer mortality in Spain: Possible role of mining and industry

    Directory of Open Access Journals (Sweden)

    Escolar-Pujolar Antonio

    2006-01-01

    Full Text Available Abstract Background Spain shows the highest bladder cancer incidence rates in men among European countries. The most important risk factors are tobacco smoking and occupational exposure to a range of different chemical substances, such as aromatic amines. Methods This paper describes the municipal distribution of bladder cancer mortality and attempts to "adjust" this spatial pattern for the prevalence of smokers, using the autoregressive spatial model proposed by Besag, York and Molliè, with relative risk of lung cancer mortality as a surrogate. Results It has been possible to compile and ascertain the posterior distribution of relative risk for bladder cancer adjusted for lung cancer mortality, on the basis of a single Bayesian spatial model covering all of Spain's 8077 towns. Maps were plotted depicting smoothed relative risk (RR estimates, and the distribution of the posterior probability of RR>1 by sex. Towns that registered the highest relative risks for both sexes were mostly located in the Provinces of Cadiz, Seville, Huelva, Barcelona and Almería. The highest-risk area in Barcelona Province corresponded to very specific municipal areas in the Bages district, e.g., Suría, Sallent, Balsareny, Manresa and Cardona. Conclusion Mining/industrial pollution and the risk entailed in certain occupational exposures could in part be dictating the pattern of municipal bladder cancer mortality in Spain. Population exposure to arsenic is a matter that calls for attention. It would be of great interest if the relationship between the chemical quality of drinking water and the frequency of bladder cancer could be studied.

    1991-01-01

    The rubber industry, acknowledged by the International Agency for Research on Cancer (IARC) to be a cancer risk technology is, because of difficulty in identifying causal factors, the subject of intensive epidemiological studies in many countries. In the presented study, cancer risk in the rubber industry was evaluated on the basis of long-term observation (1945-1985) of a cohort of 6978 male workers employed in a rubber goods factory, predominantly engaged in producing rubber footwear. The reference group was the general male population of Poland. Standardized mortality ratios (SMRs), calculated by means of the person-years method, were used in the evaluation of death risk. The observation of a whole cohort indicated an excess of cancer, in general (approx 12%), lung cancer (approx 40%) and gallbladder cancer (approx fourfold). In the subcohorts, distinguished according to peculiarities of individual production sections, cancer risk of the large intestine and larynx was significantly increased. The highest cancer risk was found in compounding, mixing, milling and vulcanizing sections. Hence, beta-naphthylamine, benzidine and solvents (benzene) were used in technological processes in the past, bladder cancer and leukemia were considered as most specific for the rubber industry. In the cohort observed, the risk of death from bladder cancer was significantly increased only in those who had been employed during the years 1945-1953, namely during the period when beta-naphthylamine was in use. No excess of deaths from leukemia was observed. PMID:1799640

  14. Cancer incidence in atomic bomb survivors. Part IV: Comparison of cancer incidence and mortality

    International Nuclear Information System (INIS)

    This report compares cancer incidence and mortality among atomic bomb survivors in the Radiation Effects Research Foundation Life Span Study (LSS) cohort. Because the incidence data are derived from the Hiroshima and Nagasaki tumor registries, case ascertainment is limited to the time (1958-1987) and geographic restrictions (Hiroshima and Nagasaki) of the registries, whereas mortality data are available from 1950-1987 anywhere in Japan. With these conditions, there were 9,014 first primary incident cancer cases identified among LSS cohort members compared with 7,308 deaths for which cancer was listed as the underlying cause of death on death certificates. When deaths were limited to those occurring between 1958-1987 in Hiroshima or Nagasaki, there were 3,155 more incident cancer cases overall, and 1,262 more cancers of the digestive system. For cancers of the oral cavity and pharynx, skin, breast, female and male genital organs, urinary system and thyroid, the incidence series was at least twice as large as the comparable mortality series. Although the incidence and mortality data are dissimilar in many ways, the overall conclusions regarding which solid cancers provide evidence of a significant dose response generally confirm the mortality findings. When either incidence or mortality data are evaluated, significant excess risks are observed for all solid cancers, stomach, colon, liver (when it is defined as primary liver cancer or liver cancer not otherwise specified on the death certificate), lung, breast, ovary and urinary bladder. No significant radiation effect is seen for cancers of the pharynx, rectum, gallbladder, pancreas, nose, larynx, uterus, prostate or kidney in either series. There is evidence of a significant excess of nonmelanoma skin cancer in the incidence data, but not in the mortality series. 19 refs., 2 figs., 10 tabs

  15. Dietary factors and cancer mortality among atomic-bomb survivors

    International Nuclear Information System (INIS)

    Dietary factors such as fruit and vegetables are thought to reduce the risk of cancer incidence and mortality. We investigated the effect of a diet rich in fruit and vegetables against the long-term effects of radiation exposure on the risk of cancer. A cohort of 36,228 atomic-bomb survivors of Hiroshima and Nagasaki, for whom radiation dose estimates were currently available, had their diet assessed in 1980. They were followed for a period of 20 years for cancer mortality. The joint-effect of fruit and vegetables intake and radiation exposure on risk of cancer death was examined, in additive (sum of effects of diet alone and radiation alone) and multiplicative (product of effects of diet alone and radiation alone) models. In the additive model, a daily intake of fruit and vegetables significantly reduced the risk of cancer deaths by 13%, compared to an intake of once or less per week. Radiation exposure of 1 Sievert (Sv) increased significantly the risk of cancer death by 48-49%. The additive joint-effects showed a lower risk of cancer among those exposed to 1 Sv who had a diet rich in vegetables (49%-13%=36%) or fruit (48%-13%=35%). The multiplicative model gave similar results. The cancer risk reduction by vegetables in exposed persons went from 52% (effect of radiation alone) to 32% (product of effect of vegetables and radiation), and cancer risk reduction by fruit was 52% (radiation alone) to 34% (product of effect of fruit and radiation). There was no significant evidence to reject either the additive or the multiplicative model. A daily intake of fruit and vegetables was beneficial to the persons exposed to radiation in reducing their risks of cancer death

    We investigated whether there might be an excess of breast and prostate cancer mortality among the population residing near Spanish industries, according to different categories of industrial groups. An ecologic study was designed to examine breast and prostate cancer mortality at a municipal level (period 1997-2006). Population exposure to pollution was estimated by means of distance from town of residence to industrial facilities. Using Besag-York-Mollié regression models with Integrated Nested Laplace approximations for Bayesian inference, we assessed the relative risk of dying from these tumors in 2-, 3-, 4-, and 5-km zones around installations, and analyzed the effect of category of industrial group. For all sectors combined, no excess risk was detected. However, excess risk of breast cancer mortality (relative risk, 95% credible interval) was detected near mines (1.10, 1.00-1.21 at 4 km), ceramic industries (1.05, 1.00-1.09 at 5 km), and ship building (1.12, 1.00-1.26 at 5 km), and excess risk of prostate cancer was detected near aquaculture for all distances analyzed (from 2.42, 1.53-3.63 at 2 km to 1.63, 1.07-2.36 at 5 km). Our findings do not support that residing in the vicinity of pollutant industries as a whole (all industrial sectors combined) is a risk factor for breast and prostate cancer mortality. However, isolated statistical associations found in our study with respect to specific industrial groups warrant further investigation. PMID:27108043

    Full Text Available Indigenous Māori women have a 60% higher breast cancer mortality rate compared with European women in New Zealand. We investigated differences in cancer biological characteristics and their impact on breast cancer mortality disparity between Māori and NZ European women.Data on 2849 women with primary invasive breast cancers diagnosed between 1999 and 2012 were extracted from the Waikato Breast Cancer Register. Differences in distribution of cancer biological characteristics between Māori and NZ European women were explored adjusting for age and socioeconomic deprivation in logistic regression models. Impacts of socioeconomic deprivation, stage and cancer biological characteristics on breast cancer mortality disparity between Māori and NZ European women were explored in Cox regression models.Compared with NZ European women (n=2304, Māori women (n=429 had significantly higher rates of advanced and higher grade cancers. Māori women also had non-significantly higher rates of ER/PR negative and HER-2 positive breast cancers. Higher odds of advanced stage and higher grade remained significant for Māori after adjusting for age and deprivation. Māori women had almost a 100% higher age and deprivation adjusted breast cancer mortality hazard compared with NZ European women (HR=1.98, 1.55-2.54. Advanced stage and lower proportion of screen detected cancer in Māori explained a greater portion of the excess breast cancer mortality (HR reduction from 1.98 to 1.38, while the additional contribution through biological differences were minimal (HR reduction from 1.38 to 1.35.More advanced cancer stage at diagnosis has the greatest impact while differences in biological characteristics appear to be a minor contributor for inequities in breast cancer mortality between Māori and NZ European women. Strategies aimed at reducing breast cancer mortality in Māori should focus on earlier diagnosis, which will likely have a greater impact on reducing breast

    A cohort of 889 men and 1077 women employed for at least 1 month between 1946 and 1984 by a former Italian leading asbestos (mainly textile) company, characterised by extremely heavy exposures often for short durations, was followed up to 1996, for a total of 53,024 person-years of observation. Employment data were obtained from factory personnel records, while vital status and causes of death were ascertained through municipality registers and local health units. We observed 222 cancer deaths compared with 116.4 expected (standardized mortality ratio, SMR=191). The highest ratios were found for pleural (SMR=4105), peritoneal (SMR=1817) and lung (SMR=282) cancers. We observed direct relationships with duration of employment for lung and peritoneal cancer, and with time since first employment for lung cancer and mesothelioma. Pleural cancer risk was independent from duration (SMR=3428 for employment or =10 years). Corresponding SMRs for lung cancer were 139, 251, 233 and 531. Nonsignificantly increased ratios were found for ovarian (SMR=261), laryngeal (SMR=238) and oro-pharyngeal (SMR=226) cancers. This study confirms and further quantifies the central role of latency in pleural mesothelioma and of cumulative exposure in lung cancer. PMID:15702125

    A mortality study was carried out in two factories producing stainless steel in order to assess lung cancer risk among workers employed in coke oven, blast and open hearth furnaces, foundry, electric furnace, hot and cold rolling mills and pickling areas. Occupational exposures of interest were chromium compounds, nickel compounds, polycyclic aromatic hydrocarbons (PAH), silica and asbestos. All male workers having at least one year of employment between 01.01.1960 and 31.12.1990 were followed up for mortality. The vital status was assessed from birth place registries. Complete job histories since date of first employment were abstracted from the company files. The smoking habits of 50% of the cohort members were known from medical records. The observed number of deaths (obs) were compared with the expected ones based on regional rates with adjustment for age, sex and calendar time (Standardized Mortality Ratio, SMR). The cohorts included 6324 (factory 1) and 5270 (factory 2) workers. The overall mortality did not differ markedly from that expected in both factories: SMR = 0.95 (obs = 1540, p = 0.05) in factory 1 and SMR = 1.06 (obs = 916, non-significant) in factory 2. SMRs for lung cancer did not differ from unity, respectively 0.99 (obs = 105) and 1.00 (obs = 54), in whole cohorts. Non-significant lung cancer excesses were observed among workers of some workshops where exposures of interest might have occurred: coke oven (SMR = 2.04), blast furnace (SMR = 1.36), open hearth furnace (SMR = 1.75), hot rolling mills (SMR = 1.29). These processes, however, are no longer involved in the study factories. Furthermore, no lung cancer excess was observed among workers employed in current workshops: electric furnaces and cold rolling mills. PMID:7732197

METHODOLOGY/PRINCIPAL FINDINGS: We tested whether frequent blood donation is associated with a lower risk of colorectal cancer in the Health Professionals Follow-up Study. We prospectively followed 35,121 men who provide the information on lifetime number of blood donations in 1992 through 2008. Serum ferritin levels were measured in a random sample of 305 men. Cox proportional hazard regression models were used to calculate the multivariable relative risks (RRs, 95%CIs after adjusting for age and other established colorectal cancer risk factors. We documented 684 incident colorectal cancer cases and 224 deaths from colorectal cancer. The mean serum ferritin levels varied from 178 µg/L for men who did not donate blood to 98 µg/L for men who had at least 30 donations. Age-adjusted results for both incidence and mortality were essentially the same as the multivariable-adjusted results. Comparing with non-donors, the multivariable RRs (95%CIs for colorectal cancer incidence were 0.92 (0.77, 1.11 for 1-5 donation, 0.85 (0.64, 1.11 for 6-9 donations, 0.96 (0.73, 1.26 for 10-19 donations, 0.91 (0.63, 1.32 for 20-29 donations, and 0.97 (0.68, 1.38 for at least 30 donations (P(trend = 0.92. The multivariable RRs for colorectal cancer mortality were 0.99 (0.72, 1.36 for 1-5 donation, 0.93 (0.57, 1.51 for 6-9 donations, 0.85 (0.50, 1.42 for 10-19 donations, and 1.14 (0.72, 1.83 for at least 20 donations (P(trend = 0.82. The results did not vary by cancer sub-sites, intake levels of total iron, heme iron, or family history of colorectal cancer. CONCLUSIONS/SIGNIFICANCE: Frequent blood donations were not associated with colorectal cancer incidence and mortality in men. Our results do not support an important role of body iron stores in colorectal carcinogenesis.

    Full Text Available In contrast to road mortality, little is known about amphibian railroad mortality. The aim of this study was to quantify amphibian mortality along a railway line as well as to investigate the relationship between the availability of breeding sites in the surrounding habitats and the monthly variation of amphibian railway mortality. The study was conducted from April to July 2011 along 45 km of the railway line Kraków - Tarnów (Poland, Małopolska province. Three species were affected by railway mortality: Bufo bufo, Rana temporaria and Pelophylax kl. esculentus. Most dead individuals (77% were adult common toads. The largest number (14 of amphibian breeding sites was located in the most heterogeneous habitats (woodland and rural areas, which coincides with the sectors of highest amphibian mortality (42% of all accidents. As in the case of roads, spring migration is the period of highest amphibian mortality (87% of all accidents on railroads. Our findings suggest that railroad mortality depends on the agility of the species, associated primarily with the ability to overcome the rails.

    Full Text Available Context While perioperative mortality after pancreaticoduodenectomy is decreasing, key factors remain to be elucidated. Objective The purpose of this study was to investigate inpatient mortality after pancreaticoduodenectomy in the NationwideInpatient Sample (NIS, a representative inpatient database in the USA. Methods Patient discharge data (diagnostic andprocedure codes and hospital characteristics were investigated for years 2009 and 2010. The inclusion criteria were aprocedure code for pancreaticoduodenectomy, elective procedure, and a pancreatic or peripancreatic cancer diagnosis. Chisquare test determined statistical significance. A logistic regression model for mortality was created from significantvariables. Results Two-thousand and 958 patients were identified with an average age of 65±12 years; 53% were male. Themean length of stay was 15±12 days with a mortality of 4% and a complication rate of 57%. Eighty-six percent of pancreaticoduodenectomy occurred in teaching hospitals. Pancreaticoduodenectomy performed in teaching hospitals in thefirst half of the academic year were associated with higher mortality than in the latter half (5.5% vs. 3.4%, P=0.005. Onlogistic regression analysis, non-surgical complications are the largest predictor of death (P

  8. Cancer mortality after multiple fluoroscopic examinations of the chest

    International Nuclear Information System (INIS)

    Total cancer deaths were not increased among 2074 women and 1277 men who were fluoroscopically examined an average of 73 and 91 times, respectively, during lung-collapse therapy for tuberculosis (TB). Patients who did not receive this form of therapy (2141 women and 1418 men) and general population rates were used for comparison. All subjects were discharged alive from eight TB sanatoria in Massachusetts between 1930 and 1954; the average follow-up was 23 years. Deaths due to breast cancer were not increased among exposed females [standardized mortality ratio (SMR) = 1.0, n = 24], and SMRs greater than 2.1 could be excluded with 95% confidence. In contrast to other series, our inability to detect a breast cancer excess was likely due to lower breast doses (66 rad) and higher average ages at exposure (28 yr) and thus lower sensitivity. A deficit of lung cancer among exposed males and females was observed (SMR = 0.8, n = 26), even though increased risks have been observed among other populations exposed to similar dose levels. The estimated average lung dose was 91 rad, and SMRs greater than 1.2 for lung cancer could be excluded with 95% confidence. Overall, this study indicates that the radiation hazard of multiple low-dose exposures experienced over many years is not greater than currently accepted estimates for breast and lung cancer. For lung cancer the radiogenic risk may be less than predicted from high-dose, single-exposure studies

    2012-01-01

    We tested the hypothesis that lifetime mortality patterns and their corresponding rates and causal factors differ among populations of stream-living salmonids. To this end, we examined the lifetime mortality patterns of several successive cohorts of two stream-living brown trout (Salmo trutta) populations in Spain and Denmark. In the southern population, we observed a consistent two-phase pattern, in which mortality was negligible during the first half of the lifetime and severe during the rest of the lifetime. In contrast, the northern population demonstrated a three-phase pattern with an earlier phase varying from negligible to severe, followed by a second stage of weak mortality, and lastly by a third life stage of severe mortality. Despite substantial differences in the mortality patterns between the two populations, the combined effect of recruitment (as a proxy of the density-dependent processes occurring during the lifetime) and mean body mass (as a proxy of growth experienced by individuals in a given cohort) explained c. 89% of the total lifetime mortality rates across cohorts and populations. A comparison with other published data on populations of stream-living brown trout within its native range highlighted lifetime mortality patterns of one, two, three and four phases, but also suggested that common patterns may occur in populations that experience similar individual growth and population density. ?? 2011 Blackwell Publishing Ltd.

    Survivors of childhood cancer have a higher mortality than the general population. We describe cause-specific long-term mortality in a population-based cohort of childhood cancer survivors. We included all children diagnosed with cancer in Switzerland (1976-2007) at age 0-14 years, who survived ≥5 years after diagnosis and followed survivors until December 31, 2012. We obtained causes of death (COD) from the Swiss mortality statistics and used data from the Swiss general population to calculate age-, calendar year-, and sex-standardized mortality ratios (SMR), and absolute excess risks (AER) for different COD, by Poisson regression. We included 3,965 survivors and 49,704 person years at risk. Of these, 246 (6.2%) died, which was 11 times higher than expected (SMR 11.0). Mortality was particularly high for diseases of the respiratory (SMR 14.8) and circulatory system (SMR 12.7), and for second cancers (SMR 11.6). The pattern of cause-specific mortality differed by primary cancer diagnosis, and changed with time since diagnosis. In the first 10 years after 5-year survival, 78.9% of excess deaths were caused by recurrence of the original cancer (AER 46.1). Twenty-five years after diagnosis, only 36.5% (AER 9.1) were caused by recurrence, 21.3% by second cancers (AER 5.3) and 33.3% by circulatory diseases (AER 8.3). Our study confirms an elevated mortality in survivors of childhood cancer for at least 30 years after diagnosis with an increased proportion of deaths caused by late toxicities of the treatment. The results underline the importance of clinical follow-up continuing years after the end of treatment for childhood cancer. PMID:26950898

    1989-12-01

    Religiously active Mormons in California are a nonsmoking population with unusually low risk for cancer. This finding is based on the results of our 1979 questionnaire survey of life-style and the 8-year (1980-1987) follow-up of mortality among 5,231 Mormon high priests and 4,613 wives 25-99 years of age. Our study, which is the first prospective cohort study of Mormons, shows low standardized mortality ratios (SMRs) for this population, relative to those for whites in the general population in the United States, which are defined as 100. The SMRs for males are 47 for all cancers, 52 for cardiovascular diseases, and 47 for all causes; the SMRs for females are 72 for all cancers, 64 for cardiovascular diseases, and 66 for all causes. For middle-aged high priests adhering to three health practices (never smoking cigarettes, engaging in regular physical activity, and getting proper sleep), the SMRs are 34 for all cancers, 14 for cardiovascular diseases, and 22 for all causes. These results have been largely replicated in an active Mormon-like subgroup (white nonsmokers attending church weekly) from a representative sample of residents of Alameda County, CA. Our findings confirm and expand on previous descriptive studies of Mormons and demonstrate how these results can be generalized. PMID:2585528

    Comparison of cancer morbidity and mortality rates between Mormons and Seventh-day-Adventists and the corresponding rates in the Federal Republic of Germany and the United States, reveals that mortality from malignant neoplasms in general is much lower in Mormons and Seventh-day Adventists than in the Federal Republic of Germany. The difference concerns in particular the tobacco-dependent tumors: compared to the rate of affected males in the Federal Republic of Germany, only some 25% of Mormon males are getting lung cancer. Similar patterns are found in laryngeal carcinoma. Tumors that are related to both alcohol and tobacco, such as carcinomas of tongue, pharynx and esophagus, are also significantly less frequent in Mormons. Malignant neoplasms of the female genital tract show distinct analogies: cervical carcinoma has a morbidity rate of only 26.7% of affected women in Germany. Accordingly, mortality rates of Mormons and Seventh-day Adventists show a significant lower level when compared with cancer data of lung, colon and rectum, and prostate from the best German cancer registry (Saarland). Some tumor rates are higher in Mormons, e.g. malignant melanoma, also all types of malignant lymphoma and myeloma. The life expectancy is generally elevated by 2-4 years in Mormons and Seventh-day Adventists. The association with the particular life style of both religious groups, especially the strict reduction of tobacco consumption, and factors of dietary and other habits is discussed. PMID:1449267

    Full Text Available BACKGROUND: Increased body mass index is related to the incidence of thyroid cancer. However, the presentation and therapeutic outcomes of different thyroid cancers and type 2 diabetes mellitus (DM have not been studied. This study investigated the effect of type 2 DM on the clinical presentations and therapeutic outcome of well-differentiated thyroid cancer. METHODS AND FINDINGS: A retrospective analysis of adult thyroid cancer patients with or without type 2 DM admitted between January 2001 and December 2010 was performed at an institution. A total of 1,687 well-differentiated thyroid cancer patients with different histological patterns were enrolled. Among these subjects, 122 were type 2 DM patients. Patients with thyroid cancer and type 2 DM were significantly older than non-DM patients. After a mean follow-up period of 5.6±0.1 years, patients with thyroid cancer and type 2 DM showed a higher percentage of disease progression than non-DM patients (24.6% vs. 17.4%. In addition, disease-specific mortality was higher in the type 2 DM group (10.7% vs. 3.8%. Thyroid cancer patients with type 2 DM showed a higher percentage of secondary primary cancers than those without DM (10.7% vs. 4.9%. Thyroid cancer-specific survival rates in the type 2 DM and non-DM groups were 82.2% and 94.9% at 5 years, 72.9% and 91.4% at 10 years, and 36.5% and 61.3% at 20 years, respectively. Multivariate analysis showed that type 2 DM was independent of thyroid cancer-specific mortality. CONCLUSION: Patients with type 2 DM and well-differentiated thyroid cancer had an advanced tumor-node-metastasis stage at the time of diagnosis and an increased disease-specific mortality. Aggressive surgical procedures and close follow-up for well-differentiated thyroid cancer patients with type 2 DM are therefore necessary.

  1. Levels and patterns of infant and child mortality in Ghana.

    Science.gov (United States)

    Gaisie, S K

    1976-02-01

    This paper attempts to measure infant and child mortality levels and also to determine their structures by utilzing the results of the 1968/69 National Demographic sample survey which was conducted under the directorship of the author. The measurement of infant and child mortality in Ghana is severely hampered by lack of reliable and adequate information on infant and child deaths. The existing data from the compulsory registration areas are deficient and can at best give an indication of only the level of urban infant and child mortalities. The tendency of censuses and surveys to miss a considerable proportion of infant and child deaths also imposes a further limitation on the extent to which the infant and child mortality rates can be accurately measured from the available data. This paper is therefore concerned with 2 major problems: 1) the adjustment of the current raw mortality data on the basis of detected errors as revealed by analytical methods and/or by the fitting of models, and 2) the estimation of infant and child mortality from independent source material (e.g., retrospective information on the number of children ever born and the number surviving). The most plausible estimate of infant mortality appears to be 133/thousand live births. Regional estimates range from 56 in the Accra Capital District to 192 in the Upper Region. Further, the urban rate is lower than the rural rate: 98 as against 161/thousand live births. An examination of child death rates by single years has shown that a large proportion of the deaths among children aged 0 to 4 occur in the 2nd year of life and that deaths in this age group account for the bulk of the deaths within the age group 1 to 4 years. The observed proportions of deaths at age 1 among all deaths within the 1 to 4 years age group range between 34 and 43%. These figures may be compared with 53% in Senegal between 1962 and 1968, and with 48 and 74% in Ibadan, Nigeria (1964/1966) and Mauritius (1961) respectively

    The present study was aimed at assessing differences between the Nordic countries, if any, in late mortality among five-year survivors of childhood cancer. All cases diagnosed before the age of 20 years, between 1960 and 1989, were collected from all Nordic cancer registries. In total, 13,689 patients were identified as five-year survivors and during the extended follow-up 12.3% of them died. Mortality was analysed by decade of diagnosis, for all sites, and for leukaemia, Hodgkin's lymphoma, and central nervous system tumours separately. Analyses were done within a Cox proportional hazards regression framework with adjustments made for gender and age at diagnosis. Hazard ratios were calculated in relation to a weighted Nordic mean based on the proportion of five-year survivors in each country. Overall late mortality was significantly higher in Denmark and Finland than in Norway and Sweden. This could not be explained by inverse differences in five-year survival. The differences diminished over time and had disappeared in the last period. The pattern was similar for both genders. The disappearance of the differences was most probably the effect of a closer collaboration between Nordic paediatric oncologists with development and implementation of common protocols for treatment of childhood cancers in all countries.

  3. Obesity and Diabetes: The Increased Risk of Cancer and Cancer-Related Mortality.

    Gallagher, Emily Jane; LeRoith, Derek

    2015-07-01

    Obesity and type 2 diabetes are becoming increasingly prevalent worldwide, and both are associated with an increased incidence and mortality from many cancers. The metabolic abnormalities associated with type 2 diabetes develop many years before the onset of diabetes and, therefore, may be contributing to cancer risk before individuals are aware that they are at risk. Multiple factors potentially contribute to the progression of cancer in obesity and type 2 diabetes, including hyperinsulinemia and insulin-like growth factor I, hyperglycemia, dyslipidemia, adipokines and cytokines, and the gut microbiome. These metabolic changes may contribute directly or indirectly to cancer progression. Intentional weight loss may protect against cancer development, and therapies for diabetes may prove to be effective adjuvant agents in reducing cancer progression. In this review we discuss the current epidemiology, basic science, and clinical data that link obesity, diabetes, and cancer and how treating obesity and type 2 diabetes could also reduce cancer risk and improve outcomes.

  4. Mortality salience increases defensive distancing from people with terminal cancer.

    2014-01-01

    Based on principles of terror management theory, the authors hypothesized that participants would distance more from a target person with terminal cancer than from a target with arthritis, and that this effect would be stronger following mortality salience. In Study 1, adults rated how similar their personalities were to a target person; in Study 2, participants arranged two chairs in preparation for meeting the target person. Both studies found that distancing from the person with terminal cancer increased after participants wrote about their own death (vs. giving a speech). Thus, death anxiety may explain why people avoid close contact with terminally ill people; further analyses suggest that gender and self-esteem may also influence such distancing from the terminally ill.

    Abstract Background: Observational studies have suggested that vitamin B supplementation is associated with cancer risk, but this association remains controversial. A pooled data-based meta-analysis was conducted to summarize the evidence from randomized controlled trials (RCTs) investigating the effects of vitamin B supplementation on cancer incidence, death due to cancer, and total mortality. Methods: PubMed, EmBase, and the Cochrane Library databases were searched to identify trials to fit our analysis through August 2015. Relative risk (RR) was used to measure the effect of vitamin B supplementation on the risk of cancer incidence, death due to cancer, and total mortality using a random-effect model. Cumulative meta-analysis, sensitivity analysis, subgroup analysis, heterogeneity tests, and tests for publication bias were also conducted. Results: Eighteen RCTs reporting the data on 74,498 individuals were included in the meta-analysis. Sixteen of these trials included 4103 cases of cancer; in 6 trials, 731 cancer-related deaths occurred; and in 15 trials, 7046 deaths occurred. Vitamin B supplementation had little or no effect on the incidence of cancer (RR: 1.04; 95% confidence interval [CI]: 0.98–1.10; P = 0.216), death due to cancer (RR, 1.05; 95% CI: 0.90–1.22; P = 0.521), and total mortality (RR, 1.00; 95% CI: 0.94–1.06; P = 0.952). Upon performing a cumulative meta-analysis for cancer incidence, death due to cancer, and total mortality, the nonsignificance of the effect of vitamin B persisted. With respect to specific types of cancer, vitamin B supplementation significantly reduced the risk of skin melanoma (RR, 0.47; 95% CI: 0.23–0.94; P = 0.032). Conclusion: Vitamin B supplementation does not have an effect on cancer incidence, death due to cancer, or total mortality. It is associated with a lower risk of skin melanoma, but has no effect on other cancers. PMID:27495015

  6. Cancer mortality of nuclear workers of CEA and COGEMA from 1969 to 1986

    International Nuclear Information System (INIS)

    Cancer mortality of the nuclear workers of CEA and COGEMA has been collected by the occupational health services of both firms from 1969 to 1986. The data are related only to the workers who died when in activity. Only very few workers left CEA and COGEMA before retirement so we consider this mortality survey as describing correctly the cancer mortality for the age groups less than 60-65 years old. Compared to the national mortality of same sex, age and calendar period, by the method of indirect standardization, the only excess observed was in the female population, linked to breast cancer mortality. The male population demonstrated a high healthy worker effect, even for cancer mortality. This study has now to be completed by an typical epidemiological cohort study in order to test cancer mortality after retirement and to discuss a possible relation with occupational exposure.

  7. Cancer mortality among French atomic energy commission workers

    International Nuclear Information System (INIS)

    An analysis of the mortality of workers employed at the Commissariat a l'Energie Atomique (CEA) between 1946 and 1994 is presented. Standardized Mortality Ratios (SMR) are computed with reference to the French national population for the period 1968-1994. 51 286 workers are included in the study. 3 784 deaths occurred between 1968 and 1994. A healthy worker effect is observed for men (SMR=0.53 Cl90%=[0.52; 0.55]) and for women (SMR=0.70 Cl90%=[0.64; 0.76]). An excess is observed for male pleural cancers (SMR=1.54, Cl90%=[1.03; 2.21]). An excess of breast cancer is observed among women, statistically significant for the 1980-1994 period (SMR=1.30, Cl90%=[1.04; 1.61]). An excess is observed for malignant melanoma for both sexes (SMR=1.38, Cl90%=[0.95; 1.96]), stronger for the 1990-1994 period (SMR=2.11, Cl90%=[1.25; 3.34]). It diminishes with age. (orig.)

    This continues the series of periodic general reports on cancer mortality in the cohort of A-bomb survivors followed by the Radiation Effects Research Foundation. The follow-up is extended by the 5 years 1986-1990, and analysis includes an additional 10,500 survivors with recently estimated radiation doses. Together these extensions add about 550,000 person-years of follow-up. The cohort analyzed consists of 86,572 subjects, of which about 60% have dose estimates of at least 0.005 Sv. During 1950-1990 there have been 3086 and 4741 cancer deaths for the less than and greater than 0.005 Sv groups, respectively. It is estimated that among these there have been approximately 420 excess cancer deaths during 19509-1990, of which about 85 were due to leukemia, For cancers other than leukemia (solid cancers), about 25% of the excess deaths in 1950-1990 occurred during the last 5 years; for those exposed as children this figure is nearly 50%. For leukemia only about 3% of the excess deaths in 1950-1990 occurred in th last 5 years. Whereas most of the excess for leukemia occurred in the first 15 years after exposure, for solid cancers the pattern of excess risk in apparently more like alife-long elevation of the natural age-specific cancer risk. 29 refs., 8 figs., 19 tabs

    Lack of birth and death registries in most of developing countries, particularly those in sub-Saharan Africa led to the establishment of Demographic Surveillance Systems (DSS) sites which monitor large population cohorts within defined geographical areas. DSS collects longitudinal data on migration, births, deaths and their causes via verbal autopsies. DSS data provide an opportunity to monitor many health indicators including mortality trends. Mortality rates in Sub-Sahara Africa show seasonal patterns due to high infant and child malaria-related mortality which is influenced by seasonal features present in environmental and climatic factors. However, it is unclear whether seasonal patterns differ by age in the first few months of life. This study provides an overview of approaches to assess, capture and detect seasonality peaks and patterns in mortality using the infant mortality data from the Rufiji DSS, Tanzania. Seasonality was best captured using Bayesian negative binomial models with time and cycle dependent seasonal parameters and autoregressive temporal error terms. Seasonal patterns are similar among different age groups during infancy and timing of their mortality peaks do not differ. Seasonality in mortality rates with two peaks per year is pronounced which corresponds to rainy seasons. Understanding of these trends is important for public health preparedness. PMID:23247213

  10. Simulation of reduced breast cancer mortality in breast cancer screening programs

    International Nuclear Information System (INIS)

    The breast cancer screening programs are an essential tool in the fight against breast cancer. Currently, many questions concerning the setup of these programs are open, namely: age range of women who undergo the same, frequency of mammography, ... The effectiveness of a program should be evaluated in terms of mortality reduction is its systematic implementation in the population. In this sense, we performed Monte Carlo simulations to assess that these reductions.

    Full Text Available Mortality due to chronic diseases has been increasing in all regions of Brazil with corresponding decreases in mortality from infectious diseases. The geographical variation in proportionate mortality for chronic diseases for 17 Brazilian state capitals for the year 1985 and their association with socio-economic variables and infectious disease was studied. Calculations were made of correlation coefficients of proportionate mortality for adults of 30 years or above due to ischaemic heart disease, stroke and cancer of the lung, the breast and stomach with 3 socio-economic variables, race, and mortality due to infectious disease. Linear regression analysis included as independent variables the % of illiteracy, % of whites, % of houses with piped water, mean income, age group, sex, and % of deaths caused by infectious disease. The dependent variables were the % of deaths due to each one of the chronic diseases studied by age-sex group. Chronic diseases were an important cause of death in all regions of Brazil. Ischaemic heart diseases, stroke and malignant neoplasms accounted for more than 34% of the mortality in each of the 17 capitals studied. Proportionate cause-specific mortality varied markedly among state capitals. Ranges were 6.3-19.5% for ischaemic heart diseases, 8.3-25.4% for stroke, 2.3-10.4% for infections and 12.2-21.5% for malignant neoplasm. Infectious disease mortality had the highest (p < 0.001 correlation with all the four socio-economic variables studied and ischaemic heart disease showed the second highest correlation (p < 0.05. Higher socio-economic level was related to a lower % of infectious diseases and a higher % of ischaemic heart diseases. Mortality due to breast cancer and stroke was not associated with socio-economic variables. Multivariate linear regression models explained 59% of the variance among state capitals for mortality due to ischaemic heart disease, 50% for stroke, 28% for lung cancer, 24% for breast cancer

    BACKGROUND: Breast cancer is the leading cause of cancer death in women worldwide. Nevertheless, it is unknown whether higher mortality after breast cancer contributes to the life-expectancy gap of 15 years in women with severe mental illness (SMI). METHODS: We estimated all-cause mortality rate......% higher for women with SMI and breast cancer (MRR: 4.27, 95% CI: 3.98-4.57). Among women with both disorders, 15% of deaths could be attributed to interaction. In a sub-cohort of women with breast cancer, the ten-year all-cause-mortality was 59% higher after taking tumor stage into account (MRR: 1.59, 95...

  17. Circular asymmetry of cancer mortality in Hiroshima and Nagasaki atomic bomb survivors

    International Nuclear Information System (INIS)

    Data on Hiroshima and Nagasaki atomic bomb survivors are used to investigate, for each city, possible circular asymmetry of cancer mortality around the hypocenter. Using the Cox regression method, and controlling for age at the time of the bomb, sex, follow-up year, distance from hypocenter, and type of shielding, it is found that cancer mortality in Hiroshima was significantly higher in the westerly direction from the hypocenter. Mortality from stomach cancer, leukemia, and colon cancer was higher in the westerly direction. In Nagasaki also cancer mortality, notably lung cancer mortality, was significantly higher in the westerly direction. Discussed are possible sources of the asymmetry, particularly the possibilities of asymmetry of epidemiologic variables and of radiation exposure, and indications for future work. (author)

    International Nuclear Information System (INIS)

    in Monte Alegre and at the control counties remained stable, but the high proportion of unascertained causes of death at the mortality database does not allow a conclusive ascertainment. SMR for all causes of death in Monte Alegre was similar to that observed at the control counties, respectively, SMR=72.9, 95% CI 70,5-75,3 and SMR=75.2 , 95% CI 76,2-77,3. No excess of cancer deaths was observed in Monte Alegre or at the control populations, and cancer mortality by gender also did not reveal statistically significant differences at the different tumor sites. Despite the use of three different approaches to estimate cancer incidence in Monte Alegre and the control counties, similar patterns were observed in the studied areas. To conclude, no evidence supporting an increase of cancer deaths in Monte Alegre was observed. (author)

    Gholamreza Abdoli

    Full Text Available In 2010, cancer deaths accounted for more than 15% of all deaths worldwide, and this fraction is estimated to rise in the coming years. Increased cancer mortality has been observed in immigrant populations, but a comprehensive analysis by country of birth has not been conducted. We followed all individuals living in Sweden between 1961 and 2009 (7,109,327 men and 6,958,714 women, and calculated crude cancer mortality rates and age-standardized rates (ASRs using the world population for standardization. We observed a downward trend in all-site ASRs over the past two decades in men regardless of country of birth but no such trend was found in women. All-site cancer mortality increased with decreasing levels of education regardless of sex and country of birth (p for trend <0.001. We also compared cancer mortality rates among foreign-born (13.9% and Sweden-born (86.1% individuals and determined the effect of education level and sex estimated by mortality rate ratios (MRRs using multivariable Poisson regression. All-site cancer mortality was slightly higher among foreign-born than Sweden-born men (MRR = 1.05, 95% confidence interval 1.04-1.07, but similar mortality risks was found among foreign-born and Sweden-born women. Men born in Angola, Laos, and Cambodia had the highest cancer mortality risk. Women born in all countries except Iceland, Denmark, and Mexico had a similar or smaller risk than women born in Sweden. Cancer-specific mortality analysis showed an increased risk for cervical and lung cancer in both sexes but a decreased risk for colon, breast, and prostate cancer mortality among foreign-born compared with Sweden-born individuals. Further studies are required to fully understand the causes of the observed inequalities in mortality across levels of education and countries of birth.

  1. Geographic autocorrelation analysis of the lung cancer mortality in Uruguay

    International Nuclear Information System (INIS)

    Objective: To analyze the geographical distribution of mortality from lung cancer in Uruguay, using spatial autocorrelation indicators, in order to identify regions of high and low risk in the period 1989-2008. Methodology: 1989-2008 interval was analyzed by grouping the data in the following periods: 1989-1991,1992-1994,1995-1997,1998-2000,2001-2003 and 2004-2008. As indicator risk S MR (Standardized Mortality Ratio) was used, with reference to the country as a entirety. The analysis was performed by calculating the index I and correlation plots space (both methods according Mo ran) for each period and the corresponding maps. The significance was determined by permutations, considering level 0.05 significance. Results: The results of the correlation coefficients for different periods were, in Men: 1989 -1991 (R = 0.29, p <0.05), 1992 -1994 (I = 0.11, N S), 1995 -1997 (R = 0.31, p <0.05); 1998 - 2000 (R = 0.24, p <0.05); 2000 - 2003 (R = 0.19, p <0.05); 2004 -2008 (R = 0.24, N S). In women: 1989 -1991 (R = -0.18, N S), 1992 -1994 (R = -0.16, N S), 1995-1997 (I = 0.18, N S); 1998 - 2000 (R = 0.06, N S); 2001-2003 (R = -0.16, N S), 2004 -2008 (I = 0.02, N S), 1989-2003 (R = -0.03, N S). Men in those departments where they met more risks Artigas were low (SM R = 0.52; 0.57; 0.61; 0.61; 0.60; 0.69), Salto (SM R = 0.52; 0.57; 0.58; 0.68; 0.76; 0.75), Black River (SM R = 0.69; 0.73; 0.76; 0.93; 0.73; 1.29) and Paysandu (SMR = 0.87; 0.85; 0.96; 0.79; 0.89; 0.92) in the respective periods. In women the 0.55; 0.78) Also, in the respective periods. Given the low number of cases in women the period 1989-2003 was also considered together to obtain one SMR Black River = 0.63 and jumped SMR = 0.68. Conclusions: In men, the existence of spatial autocorrelation was identified statistically significant, with stable results in the last 2 decades analyzed. This was not observed in women. The results found in males suggest the existence a region of lower mortality from lung cancer

    Background Medullary thyroid cancer (MTC) is a rare thyroid cancer accounting for 5 % of all thyroid malignancies. The purpose of our study was to design a predictive nomogram for cancer-specific mortality (CSM) utilizing clinical, pathological, and biochemical variables in patients with MTC. Methods MTC patients managed entirely at Memorial Sloan-Kettering Cancer Center between 1986 and 2010 were identified. Patient, tumor, and treatment characteristics were recorded, and variables predictive of CSM were identified by univariable analyses. A multivariable competing risk model was then built to predict the 10-year cancer specific mortality of MTC. All predictors of interest were added in the starting full model before selection, including age, gender, pre- and postoperative serum calcitonin, pre- and postoperative CEA, RET mutation status, perivascular invasion, margin status, pathologic T status, pathologic N status, and M status. Stepdown method was used in model selection to choose predictive variables. Results Of 249 MTC patients, 22.5 % (56/249) died from MTC, whereas 6.4 % (16/249) died secondary to other causes. Mean follow-up period was 87 ± 67 months. The seven variables with the highest predictive accuracy for cancer specific mortality included age, gender, postoperative calcitonin, perivascular invasion, pathologic T status, pathologic N status, and M status. These variables were used to create the final nomogram. Discrimination from the final nomogram was measured at 0.77 with appropriate calibration. Conclusions We describe the first nomogram that estimates cause-specific mortality in individual patients with MTC. This predictive nomogram will facilitate patient counseling in terms of prognosis and subsequent clinical follow up. PMID:25366585

  8. Relation between cancer incidence or mortality and external natural background radiation in Japan

    International Nuclear Information System (INIS)

    Analysis was performed on the relationships between the organ dose-equivalent rate due to natural background radiation (mSv/a) and three parameters of cancer risk: the age-adjusted cancer incidence (patients x 105 persons x a-1) in 13 large areas, the standardized mortality ratio of cancers in 46 large areas, and the cancer mortality in the population aged more than 40 years old (cancer deaths x 105 persons x a-1) in 649 small areas. The age-adjusted liver cancer incidence in males fitted the exponential model significantly (p<0.01) and the relationship of stomach cancer mortality of aged males in small areas fitted the linear model significantly (p<0.05). No relationship was observed with regard to female cancer in either case. The relationships between the three parameters and various other cancers of both sexes were not statistically significant.

  10. Environmental Predictors of US County Mortality Patterns on a National Basis.

    Directory of Open Access Journals (Sweden)

    Melissa P L Chan

    Full Text Available A growing body of evidence has found that mortality rates are positively correlated with social inequalities, air pollution, elevated ambient temperature, availability of medical care and other factors. This study develops a model to predict the mortality rates for different diseases by county across the US. The model is applied to predict changes in mortality caused by changing environmental factors. A total of 3,110 counties in the US, excluding Alaska and Hawaii, were studied. A subset of 519 counties from the 3,110 counties was chosen by using systematic random sampling and these samples were used to validate the model. Step-wise and linear regression analyses were used to estimate the ability of environmental pollutants, socio-economic factors and other factors to explain variations in county-specific mortality rates for cardiovascular diseases, cancers, chronic obstructive pulmonary disease (COPD, all causes combined and lifespan across five population density groups. The estimated models fit adequately for all mortality outcomes for all population density groups and, adequately predicted risks for the 519 validation counties. This study suggests that, at local county levels, average ozone (0.07 ppm is the most important environmental predictor of mortality. The analysis also illustrates the complex inter-relationships of multiple factors that influence mortality and lifespan, and suggests the need for a better understanding of the pathways through which these factors, mortality, and lifespan are related at the community level.

    BACKGROUND: Delay in the diagnosis of cancer is generally considered unacceptable. However, observational studies often show an inverse association between the length of the diagnostic interval and mortality. Paradoxically, patients diagnosed more rapidly have higher mortality rates than patients...... with longer wait in the primary and secondary health care sector. AIM: To examine whether the waiting time paradox is manifest in the Danish health care system. MATERIALS & METHODS: The study was based on data on hospital discharge diagnoses for the 2004-2005 period, extracted from population...... 1270 cancer patients. Mortality varied across cancer diagnosis. There were no associations between duration and mortality for breast and skin cancer. For lung, prostate, and colorectal cancer a short diagnostic interval (0-14 days) was associated with highest mortality. CONCLUSION: The waiting-time-paradox...

    The aims of the study were to understand the racial/ethnic differences in cost of care and mortality in Medicare elderly with advanced stage prostate cancer.This retrospective, observational study used SEER-Medicare data. Cohort consisted of 10,509 men aged 66 or older and diagnosed with advanced-stage prostate cancer between 2001and 2004. The cohort was followed retrospectively up to 2009. Racial/ethnic variation in cost was analyzed using 2 part-models and quantile regression. Step-wise GLM log-link and Cox regression was used to study the association between race/ethnicity and cost and mortality. Propensity score approach was used to minimize selection bias.Pattern of cost and mortality varies between racial/ethnic groups. Compared with other racial/ethnic groups, non-Hispanic white patients had higher unadjusted costs in treatment and follow-up phases. Quintile regression results indicated that in treatment phase, Hispanics had higher costs in the 95th quantile and non-Hispanic blacks had lower cost in the 95th quantile, compared with non-Hispanic white men. In terminal phase non-Hispanic blacks and Hispanics had higher cost. After controlling for treatment, all-cause and prostate cancer-specific mortality was not significant for non-Hispanic black men, compared with non-Hispanic white men. However, for Asians, mortality remained significantly lower compared with non-Hispanic white men.In conclusion, relationship between race/ethnicity, cost of care, and mortality is intricate. For non-Hispanic black men, disparity in mortality can be attributed to treatment differences. To reduce racial/ethnic disparities in prostate cancer care and outcomes, tailored policies to address underuse, overuse, and misuse of treatment and health services are necessary. PMID:26266389

    Full Text Available Normal 0 21 false false false ES-CO X-NONE X-NONE Introduction: In Colombia, information on cancer morbidity at the population level is limited. Incidence es­timates for most regions are based on mortality data. To improve the validity of these estimates, it is necessary that other population-based cancer registries, as well as Cali, provide cancer risk information. Objective: To describe the incidence and cancer mortality in the municipality of Pasto within the 1998-2007 period. Methodology: The study population belongs to rural and urban areas of the municipality of Pasto. Collection, processing, and systematization of the data were performed according to internationally standardized parame­ters for population-based cancer registries. The cancer incidence and mortality rates were calculated by gender, age, and tumor site. Results: During the 1998-2007 period 4,986 new cases of cancer were recorded of which 57.7% were in female. 2,503 deaths were presented, 52% in female. Neoplasm-associated infections are the leading cause of cancer morbidity in Pasto: stomach cancer in males and cervical cancer in females. Discussion: Cancer in general is a major health problem for the population of the municipality of Pasto. The overall behavior of the increasing incidence and cancer mortality in relation to other causes of death show the need to implement and strengthen prevention and promotion programs, focusing especially on tumors that produce greater morbidity and mortality in the population.

    Cells usually undergo a long journey of evolution during the progression from normal to precancerous cells and finally to full-fledged cancer cells. Multiple genomic aberrations are acquired during this journey that could either act as drivers to confer significant growth advantages or act as passengers with little effect on the tumor growth. Recent advances in sequencing technology have made it feasible to decipher the evolutionary course of a cancer cell on a genome-wide level by evaluating the relative number of mutated alleles. Novel terms such as chromothripsis and chromoplexy have been introduced to describe the newly identified patterns of cancer genome evolution. These new insights have greatly expanded our understanding of the initiation and progression of cancers, which should aid in improving the efficiency of cancer management and treatment.

  19. Applications of Machine learning in Prediction of Breast Cancer Incidence and Mortality

    International Nuclear Information System (INIS)

    Breast cancer is one of the leading causes of cancer deaths for the female population in both developed and developing countries. In this work we have used the baseline descriptive data about the incidence (new cancer cases) of in situ breast cancer among Wisconsin females. The documented data were from the most recent 12-years period for which data are available. Wiscons in cancer incidence and mortality (deaths due to cancer) that occurred were also considered in this work. Artificial Neural network (ANN) have been successfully applied to problems in the prediction of the number of new cancer cases and mortality. Using artificial intelligence (AI) in this study, the numbers of new cancer cases and mortality that may occur are predicted.

  20. Pattern of Morbidity and Mortality in Kurdistan / Iraq with an Emphasis on Exposure to Chemical Weapon

    International Nuclear Information System (INIS)

    A cross-sectional survey was carried out in kurdistan -Iraq during the period 2000-2001 to determine patterns of morbidity and mortality among kurdistan population with special emphasis on those exposed to bombs and shell injuries and chemical weapons. Kurdistan was divided in to 300 sectors; from each sector, one household was selected randomly. The total study samples were 6805 including number of the household who have died since 1935. They have a male: female ratio of 1.03:1. An interview was carried out using a special questionnaire form. The mean age of the sample was 51.5 ± 0.6 years (51.1 ± 0.75 for males and 52.9 ± 0.97 for females ) 1.5% and 2.8% of surveyed population have been exposed to non - chemical weapons (bomb and shells ) or chemical weapons , respectively; 0.23% of the alive population had cancer at the time of the study. 12.6% in the study sample were complaining from respiratory disease and 6.5 had a history of miscarriage and stillbirth. Both complaints might be attributed to expose to chemical weapons. 869 (12.5 %) of the study have died since 1935, 68.4% of them have died during the period 1980 - 1999. 3 % of all deaths were due to exposure to shells or chemical weapons; 7.9 % were lost in Al - anfal campaign in 1980s of the last century. 8.5 % of all death were due to cancer probably due to exposure to chemical weapons.

    2014-01-01

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

  7. Study of mortality and cancer incidence among the offspring of atomic bomb survivors. 1946-1990

    International Nuclear Information System (INIS)

    The mortality and cancer incidence among offspring of atomic bomb survivors whose exposure dose was estimated in DS86 (Dose System 1986) were studied as one of means to evaluate the genetic influence of atomic bomb radiation. Big malformation incidence and mortality of subjects with the malformation were also studied. Death and its cause were traced from the city register and certificate of death of 67,586 offspring born in 1946-1984. Cancer was confirmed by certificate of death until 1957 and by cancer registration after 1958. Big malformation and the mortality were traced from clinical diagnostic records at birth or at necropsy, of 9-month examination after birth and of certificate of death. Comparisons were made in general and the offspring's age-related mortalities and in mortality or cancer incidence in relation to the radiation doses the parents had been exposed to. The comparisons showed no statistically significant relationships in those examined parameters. (K.H.)

    Full Text Available Background and objective The aim of this study is to analyze lung cancer epidemiological trend and estimate lung cancer burden in China. Methods Lung cancer age specific mortality and incidence rate ratios in different areas and sexes were obtained from national cancer registration database in 2004 and 2005. Cancer crude mortalities were retrieved from the database of the third national death survey, 2004-2005. Age specific incidence rates of lung cancer were calculated using mortality and M/I ratios. Annual percent change (APC was estimated by log regression model using Joint Point software by analyzing pooled lung cancer incidence data from 10 cancer registries from 1988 to 2005. Results The total estimated new cases and deaths of lung cancer in 2005 were 536 407 and 475 768 which were higher in male than in female. There was 1.63% increase of lung cancer incidence per year from 1988 to 2005, however, the trend showed a slowdown by 0.55% annually after adjusted by age. Conclusion Lung cancer is one of major health issues in China and the burden is getting serious. Ageing population is main cause for increasing incidence and mortality of lung cancer. Effective cancer prevention and control is imperative. Especially, tobacco control should be carried out in statewide.

    The study examines spatial patterns of effects of high temperature extremes on cardiovascular mortality in the Czech Republic at a district level during 1994-2009. Daily baseline mortality for each district was determined using a single location-stratified generalized additive model. Mean relative deviations of mortality from the baseline were calculated on days exceeding the 90th percentile of mean daily temperature in summer, and they were correlated with selected demographic, socioeconomic, and physical-environmental variables for the districts. Groups of districts with similar characteristics were identified according to socioeconomic status and urbanization level in order to provide a more general picture than possible on the district level. We evaluated lagged patterns of excess mortality after hot spell occurrences in: (i) urban areas vs. predominantly rural areas; and (ii) regions with different overall socioeconomic level. Our findings suggest that climatic conditions, altitude, and urbanization generally affect the spatial distribution of districts with the highest excess cardiovascular mortality, while socioeconomic status did not show a significant effect in the analysis across the Czech Republic as a whole. Only within deprived populations, socioeconomic status played a relevant role as well. After taking into account lagged effects of temperature on excess mortality, we found that the effect of hot spells was significant in highly urbanized regions, while most excess deaths in rural districts may be attributed to harvesting effects.

    Full Text Available A prospective ecological evaluation of mortality from common malignancies with dietary risk factors and alcohol consumption was carried out among 10 state capitals of Brazil. Regression analysis was used to examine the association of dietary intake with mortality rates of the most common cancers among adults age 30 years and older. Age-adjusted cancer mortality rates varied 2.4 to 3.3 fold across the state capitals. A positive relationship was observed between energy intake and colon, lung, and esophageal cancer (p<=0.02 for each. Colon cancer mortality was positively associated with consumption of total fat, eggs, alcohol, mate tea, cereals, and vegetables (p<=0.01. Lung cancer was positively associated with mate and cereal intake (p<0.05. Stomach cancer was associated with consumption of eggs (p=0.04; and negatively associated with consumption of high fiber foods, fruits, and vitamin A and C (p<=0.05. Esophageal cancer was positively associated with fat intake, mate and cereals (p<=0.05 and negatively associated with vitamin A (p=0.02; prostate cancer was negatively associated with vitamin C (p=0.007. Breast cancer was not associated with any of the factors studied. The marked variation in cancer mortality rates in Brazil may be partially related to the high variation in dietary components or other diet associated factors.

  11. Chernobyl cleanup workers from Estonia: follow-up for cancer incidence and mortality

    International Nuclear Information System (INIS)

    This study examined cancer incidence (1986–2008) and mortality (1986–2011) among the Estonian Chernobyl cleanup workers in comparison with the Estonian male population. The cohort of 4810 men was followed through nationwide population, mortality and cancer registries. Cancer and death risks were measured by standardised incidence ratio (SIR) and standardised mortality ratio (SMR), respectively. Poisson regression was used to analyse the effects of year of arrival, duration of stay and time since return on cancer and death risks. The SIR for all cancers was 1.06 with 95% confidence interval 0.93–1.20 (232 cases). Elevated risks were found for cancers of the pharynx, the oesophagus and the joint category of alcohol-related sites. No clear evidence of an increased risk of thyroid cancer, leukaemia or radiation-related cancer sites combined was apparent. The SMR for all causes of death was 1.02 with 95% confidence interval 0.96–1.08 (1018 deaths). Excess mortality was observed for mouth and pharynx cancer, alcohol-related cancer sites together and suicide. Duration of stay rather than year of arrival was associated with increased mortality. Twenty-six years of follow-up of this cohort indicates no definite health effects attributable to radiation, but the elevated suicide risk has persisted. (paper)

    Background Breakfast eating habits are a dietary pattern marker and appear to be a useful predictor of a healthy lifestyle. Many studies have reported the unhealthy effects of skipping breakfast. However, there are few studies on the association between skipping breakfast and mortality. In the present study, we examined the association between skipping breakfast and mortality from cancer, circulatory diseases and all causes using data from a large-scale cohort study, the Japan Collaborative Cohort Study (JACC) Study. Methods A cohort study of 34,128 men and 49,282 women aged 40–79 years was conducted, to explore the association between lifestyle and cancer in Japan. Participants completed a baseline survey during 1988 to 1990 and were followed until the end of 2009. We classified participants into two groups according to dietary habits with respect to eating or skipping breakfast and carried out intergroup comparisons of lifestyle. Multivariate analysis was performed using the Cox proportional hazard regression model. Results There were 5,768 deaths from cancer and 5,133 cases of death owing to circulatory diseases and 17,112 cases for all causes of mortality during the median 19.4 years follow-up. Skipping breakfast was related to unhealthy lifestyle habits. After adjusting for confounding factors, skipping breakfast significantly increased the risk of mortality from circulatory diseases [hazard ratio (HR) = 1.42] and all causes (HR = 1.43) in men and all causes mortality (HR = 1.34) in women. Conclusion Our findings showed that skipping breakfast is associated with increasing risk of mortality from circulatory diseases and all causes among men and all causes mortality among women in Japan.

    Full Text Available Selenium (Se is an essential trace element for selenoprotein biosynthesis. Selenoproteins have been implicated in cancer risk and tumor development. Selenoprotein P (SePP serves as the major Se transport protein in blood and as reliable biomarker of Se status in marginally supplied individuals. Among the different malignancies, renal cancer is characterized by a high mortality rate. In this study, we aimed to analyze the Se status in renal cell cancer (RCC patients and whether it correlates to cancer-specific mortality. To this end, serum samples of RCC patients (n = 41 and controls (n = 21 were retrospectively analyzed. Serum Se and SePP concentrations were measured by X-ray fluorescence and an immunoassay, respectively. Clinical and survival data were compared to serum Se and SePP concentrations as markers of Se status by receiver operating characteristic (ROC curve and Kaplan-Meier and Cox regression analyses. In our patients, higher tumor grade and tumor stage at diagnosis correlated to lower SePP and Se concentrations. Kaplan-Meier analyses indicated that low Se status at diagnosis (SePP<2.4 mg/l, bottom tertile of patient group was associated with a poor 5-year survival rate of 20% only. We conclude that SePP and Se concentrations are of prognostic value in RCC and may serve as additional diagnostic biomarkers identifying a Se deficit in kidney cancer patients potentially affecting therapy regimen. As poor Se status was indicative of high mortality odds, we speculate that an adjuvant Se supplementation of Se-deficient RCC patients might be beneficial in order to stabilize their selenoprotein expression hopefully prolonging their survival. However, this assumption needs to be rigorously tested in prospective clinical trials.

    Full Text Available Background: The 4 th millennium development goals (2002 reported that sub-Saharan Africa countries including Nigeria have a persistently high childhood mortality rates in-spite of all the preventive and interventional measures to reduce this ugly trend. Patients and Methods: Childhood mortality data was obtained from the medical records department and post-mortem records of the pathology departments over a 5-year period from January 2007 to December 2011. The selection criteria include all case notes with mortality records involving children admitted into the paediatrics department through the labour ward and the obstetrics theater, children emergency unit (CHER, paediatric out-patient clinic. Results : A total of 12,442 children were admitted during this period. Of this, 711 paediatric deaths were documented accounting for 17.5%. The male to female mortality ratio was 1.4:1. The age range was from birth to 17 years. Neonatal deaths accounted for the most common cause of death constituting 344 (48.4% of all deaths. Among the neonatal mortality patterns, severe birth asphyxia/perinatal asphyxia was the most common cause of early neonatal deaths accounting for 97 (28.2%. Septicaemia accounted for the most frequent cause of infant mortality accounting for 28 (21.8%. Among the under-5 age group, severe malaria constituted the most common cause of death accounting for 52 (36.6% cases while malignancy topped the list of 5-17 years mortality rate constituting 15 (15.4% cases. Conclusion: Perinatal and neonatal deaths constitute the vast majority of death in our environment with most of the deaths resulting from severe birth asphyxias, prematurity. Again in the post-neonatal period, infections and other preventable diseases constitute the most common cause of death in children of under age group of five years. Above 5 years childhood malignancies constitutes the highest mortality pattern.

  18. Drought characteristics drive patterns in widespread aspen forest mortality across the western United States

    Widespread drought-induced forest mortality has been documented across the globe in the last few decades and influences land-atmosphere interactions, biodiversity, carbon sequestration, and biophysical and biogeochemical feedbacks to climate change. These rapid mortality events are currently not well-captured in current vegetation models, limiting the ability to predict them. While many studies have focused on the plant physiological mechanisms that mediate vegetation mortality, the characteristics of drought seasonality, sequence, severity and duration that drive mortality events have received much less attention. These characteristics are particularly relevant in light of changing precipitation regimes, changes to snowpack and snowmelt, and increasing temperature stress associated with climate change. We examine the characteristics of drought associated with the recent widespread mortality of trembling aspen (Populus tremuloides) across much of the western United States. We combine a regional model of watershed-level aspen mortality with in situ tissue isotopic analysis of water source to analyze the roles of drought seasonality, severity, and duration in this mortality event, including raw climate variables, derived drought indices, and variables generated by a climate envelope approach. We found that variables pertaining to spring temperatures and spring-summer water deficit, especially during the peak severity of drought, best capture regional mortality patterns, though multi-year drought variables did improve the model. Field water isotopic analysis of aspen water source over a growing season and during moderate seasonal water stress corroborate the regional model by indicating that aspen clones generally utilize surface water with little plasticity during drought stress. These results suggest that drought characteristics can play an important role in mediating widespread forest mortality and have implications for the future vulnerability of trembling aspen

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

    Xiaorong Wang

    Full Text Available OBJECTIVE: This study was conducted to assess the relationship of mortality from lung cancer and other selected causes to asbestos exposure levels. METHODS: A cohort of 1539 male workers from a chrysotile mine in China was followed for 26 years. Data on vital status, occupation and smoking were collected from the mine records and individual contacts. Causes and dates of death were further verified from the local death registry. Individual cumulative fibre exposures (f-yr/ml were estimated based on converted dust measurements and working years at specific workshops. Standardized mortality ratios (SMRs for lung cancer, gastrointestinal (GI cancer, all cancers and nonmalignant respiratory diseases (NMRD stratified by employment years, estimated cumulative fibre exposures, and smoking, were calculated. Poisson models were fitted to determine exposure-response relationships between estimated fibre exposures and cause-specific mortality, adjusting for age and smoking. RESULTS: SMRs for lung cancer increased with employment years at entry to the study, by 3.5-fold in ≥ 10 years and 5.3-fold in ≥ 20 years compared with <10 years. A similar trend was seen for NMRD. Smokers had greater mortality from all causes than nonsmokers, but the latter also had slightly increased SMR for lung cancer. No excess lung cancer mortality was observed in cumulative exposures of <20 f-yrs/ml. However, significantly increased mortality was observed in smokers at the levels of ≥ 20 f-yrs/ml and above, and in nonsmokers at ≥ 100 f-yrs/ml and above. A similarly clear gradient was also displayed for NMRD. The exposure-response relationships with lung cancer and NMRD persisted in multivariate analysis. Moreover, a clear gradient was shown in GI cancer mortality when age and smoking were adjusted for. CONCLUSION: There were clear exposure-response relationships in this cohort, which imply a causal link between chrysotile asbestos exposure and lung cancer and nonmalignant

    Full Text Available Abstract Background The objective of this study was to assess trends in cancer mortality by educational level in Barcelona from 1992 to 2003. Methods The study population comprised Barcelona inhabitants aged 20 years or older. Data on cancer deaths were supplied by the system of information on mortality. Educational level was obtained from the municipal census. Age-standardized rates by educational level were calculated. We also fitted Poisson regression models to estimate the relative index of inequality (RII and the Slope Index of Inequalities (SII. All were calculated for each sex and period (1992–1994, 1995–1997, 1998–2000, and 2001–2003. Results Cancer mortality was higher in men and women with lower educational level throughout the study period. Less-schooled men had higher mortality by stomach, mouth and pharynx, oesophagus, larynx and lung cancer. In women, there were educational inequalities for cervix uteri, liver and colon cancer. Inequalities of overall and specific types of cancer mortality remained stable in Barcelona; although a slight reduction was observed for some cancers. Conclusion This study has identified those cancer types presenting the greatest inequalities between men and women in recent years and shown that in Barcelona there is a stable trend in inequalities in the burden of cancer.

  2. Regional Inequalities in Lung Cancer Mortality in Belgium at the Beginning of the 21st Century: The Contribution of Individual and Area-Level Socioeconomic Status and Industrial Exposure.

    Directory of Open Access Journals (Sweden)

    Full Text Available Being a highly industrialized country with one of the highest male lung cancer mortality rates in Europe, Belgium is an interesting study area for lung cancer research. This study investigates geographical patterns in lung cancer mortality in Belgium. More specifically it probes into the contribution of individual as well as area-level characteristics to (sub-district patterns in lung cancer mortality. Data from the 2001 census linked to register data from 2001-2011 are used, selecting all Belgian inhabitants aged 65+ at time of the census. Individual characteristics include education, housing status and home ownership. Urbanicity, unemployment rate, the percentage employed in mining and the percentage employed in other high-risk industries are included as sub-district characteristics. Regional variation in lung cancer mortality at sub-district level is estimated using directly age-standardized mortality rates. The association between lung cancer mortality and individual and area characteristics, and their impact on the variation of sub-district level is estimated using multilevel Poisson models. Significant sub-district variations in lung cancer mortality are observed. Individual characteristics explain a small share of this variation, while a large share is explained by sub-district characteristics. Individuals with a low socioeconomic status experience a higher lung cancer mortality risk. Among women, an association with lung cancer mortality is found for the sub-district characteristics urbanicity and unemployment rate, while for men lung cancer mortality was associated with the percentage employed in mining. Not just individual characteristics, but also area characteristics are thus important determinants of (regional differences in lung cancer mortality.

    In 2010, cancer deaths accounted for more than 15% of all deaths worldwide, and this fraction is estimated to rise in the coming years. Increased cancer mortality has been observed in immigrant populations, but a comprehensive analysis by country of birth has not been conducted. We followed all individuals living in Sweden between 1961 and 2009 (7,109,327 men and 6,958,714 women), and calculated crude cancer mortality rates and age-standardized rates (ASRs) using the world population for standardization. We observed a downward trend in all-site ASRs over the past two decades in men regardless of country of birth but no such trend was found in women. All-site cancer mortality increased with decreasing levels of education regardless of sex and country of birth (p for trend Iceland, Denmark, and Mexico had a similar or smaller risk than women born in Sweden. Cancer-specific mortality analysis showed an increased risk for cervical and lung cancer in both sexes but a decreased risk for colon, breast, and prostate cancer mortality among foreign-born compared with Sweden-born individuals. Further studies are required to fully understand the causes of the observed inequalities in mortality across levels of education and countries of birth. PMID:24682217

    Full Text Available Background: 9%–15% of all lung cancers are attributable to occupational exposures. Reports are disparate regarding elevated lung cancer mortality risk among workers employed at uranium gaseous diffusion plants.Objective: To investigate whether external radiation exposure is associated with lung cancer mortality risk among uranium gaseous diffusion workers.Methods: A cohort of 6820 nuclear industry workers employed from 1952 to 2003 at the Paducah uranium gaseous diffusion plant (PGDP was assembled. A job-specific exposure matrix (JEM was used to determine likely toxic metal exposure categories. In addition, radiation film badge dosimeters were used to monitor cumulative external ionizing radiation exposure. International Classification for Disease (ICD codes 9 and 10 were used to identify 147 lung cancer deaths. Logistic and proportional hazards regression were used to estimate lung cancer mortality risk.Results: Lung cancer mortality risk was elevated among workers who experienced external radiation >3.5 mrem and employment duration >12 years.Conclusion: Employees of uranium gaseous diffusion plants carry a higher risk of lung cancer mortality; the mortality is associated with increased radiation exposure and duration of employment.

  6. Cosmic radiation and mortality from cancer among male German airline pilots: extended cohort follow-up

    International Nuclear Information System (INIS)

    Commercial airline pilots are exposed to cosmic radiation and other specific occupational factors, potentially leading to increased cancer mortality. This was analysed in a cohort of 6,000 German cockpit crew members. A mortality follow-up for the years 1960–2004 was performed and occupational and dosimetry data were collected for this period. 405 deaths, including 127 cancer deaths, occurred in the cohort. The mortality from all causes and all cancers was significantly lower than in the German population. Total mortality decreased with increasing radiation doses (rate ratio (RR) per 10 mSv: 0.85, 95 % CI: 0.79, 0.93), contrasting with a non-significant increase of cancer mortality (RR per 10 mSv: 1.05, 95 % CI: 0.91, 1.20), which was restricted to the group of cancers not categorized as radiogenic in categorical analyses. While the total and cancer mortality of cockpit crew is low, a positive trend of all cancer with radiation dose is observed. Incomplete adjustment for age, other exposures correlated with duration of employment and a healthy worker survivor effect may contribute to this finding. More information is expected from a pooled analysis of updated international aircrew studies.

    Full Text Available OBJECTIVE: To describe the temporal trends in female breast cancer mortality rates in Brazil in its macro-regions and states between 1980 and 2009. METHODS: This was an ecological time-series study using data on breast cancer deaths registered in the Mortality Data System (SIM/WHO and census data on the resident population collected by the Brazilian Institute of Geography and Statistics (IBGE/WHO. Joinpoint regression analyses were used to identify the significant changes in trends and to estimate the annual percentage change (APC in mortality rates. RESULTS: Female breast cancer mortality rates in Brazil tended to stabilize from 1994 onward (APC = 0.4%. Considering the Brazilian macro-regions, the annual mortality rates decreased in the Southeast, stabilized in the South and increased in the Northeast, North, and Midwest. Only the states of Sao Paulo (APC = -1.9%, Rio Grande do Sul (APC = -0.8% and Rio de Janeiro (APC = -0.6% presented a significant decline in mortality rates. The greatest increases were found in Maranhao (APC=12%, Paraiba (APC=11.9%, and Piaui (APC=10.9%. CONCLUSION: Although there has been a trend toward stabilization in female breast cancer mortality rates in Brazil, when the mortality rate of each macro-region and state is analyzed individually, considerable inequalities are found, with rate decline or stabilization in states with higher socioeconomic levels and a substantial increase in those with lower socioeconomic levels.

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

    Directory of Open Access Journals (Sweden)

    Jari Haukka

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

    OBJECTIVE To assess the impact of stom'ach cancer on the Chinese population by epidemiological analysis of its distributional mortality.METHODS Data from 1990-1992 on stomach cancer mortality collected by a sampling survey involved one tenth of the total Chinese population.RESULTS The crude mortality rate of stomach cancer in China was 25.2per 105 (32.8 per 105for males and 17.0 per 105 for females), which comprised23.2% of the total cancer deaths from 1990 to 1992, making stomach cancerthe leading cause of cancer death. The stomach cancer mortality rate ofmales was 1.9 times of that of females. The Chinese mortality rates ofstomach cancer adjusted by the world standard population were 40.8 per105 and 18.6 per 105 for males and females, which were 4.2-7.9 (for males)and 3.8-8.0 (for females) times of those in developed countries. Age-adjusted mortality rates of stomach cancer in China have distinctgeographical differences: form the lowest of 2.5 per 105 to the highest of153.0 per 105 in the 263 selected sites, and 15.3 per 105 in urban areas and24.4 per 105 in rural areas, a difference of 1.6 times.CONCW$10N The prevention and treatment of stomach cancer in L;n~na,especially in the countryside and the under-developed areas in thenorthwest, should be a long-term focus in preventing of cancers of thedigestive system. Urgent measures for prevention and early detection of stomach cancer should be taken.

  11. Cigarette smoking and radiation exposure in relation to cancer mortality, Hiroshima and Nagasaki

    International Nuclear Information System (INIS)

    Cancer mortality among 40,498 Hiroshima and Nagasaki residents was examined in relation to cigarette smoking habits and estimated atomic bomb radiation exposure. Relative risk models that are either multiplicative or additive in the two exposures (smoking radiation) were emphasized. Most analyses were directed toward all nonhematologic cancer, stomach cancer, lung cancer, or digestive cancer other than stomach, for which there were, respectively, 1,725, 658, 281, and 338 deaths in the follow-up period of this study. Persons heavily exposed to both cigarette smoke and radiation were found to have significantly lower cancer mortality than multiplcative relative risk models would suggest for all nonhematologic cancer, stomach cancer, and digestive cancer other than stomach. Surprisingly, the relative risk function appeared not only to be submultiplicative for these cancer sites, but to be subadditive as well. The lung cancer relative risk function could not be distinguished from either a multiplicative or an additive form. The number of deaths was sufficient to permit some more detailed study of all nonhematologic cancer mortality: Relative risk functions appeared to be consistent between males and females though a paucity of heavy smoking females limits the precision of this comparison.

  13. Mortality from cancers of major sites in female radium dial workers

    International Nuclear Information System (INIS)

    The female radium dial workers have now experienced significant mortality from cancers other than the bone sarcomas and head carcinomas long known to be radium induced. The relationships of radium exposure to mortality from cancers of the stomach, pancreas, colon, rectum, liver, lung, breast, cervix, and corpus uteri, and from leukemia were studied in 1,285 pre-1930 dial workers. Mortality was compared with that expected from rates for US white females, with and without adjustment for local area mortality rates, and with mortality in dial workers exposed from 1930 to 1949. For the 693 cases whose body content of radium has been measured since 1955, dose-response relationships of cancer to systemic intake of radium and duration of employment were examined. Liver, pancreatic, cervical, and uterine cancers were clearly unrelated to radium exposure. Other cancers of the digestive tract appeared to be indirectly, if at all, associated with work in radium facilities. Lung cancer requires further investigation; inhalation exposures of the dial workers were reviewed. Analyses of the breast cancer data uncovered several observations inconsistent with the previously suggested causal association with radium exposure. Multiple myeloma was also reviewed. A threefold excess risk of death due to multiple myeloma has occurred, but is more closely correlated with duration of employment (a surrogate for external gamma radiation) than with radium intake

    Although elevated resting heart rate (RHR) has been shown to be associated with mortality in the general population and patients with certain diseases, no study has examined this association in patients with breast cancer. A total of 4786 patients with stage I-III breast cancer were retrospectively selected from the Severance hospital breast cancer registry in Seoul, Korea. RHR was measured at baseline and the mean follow-up time for all patients was 5.0 ± 2.5 years. Hazard ratios (HRs) with 95 % confidence intervals (CIs) were calculated using Cox regression models. After adjustment for prognostic factors, patients in the highest quintile of RHR (≥85 beat per minute (bpm)) had a significantly higher risk of all-cause mortality (HR: 1.57; 95 %CI 1.05-2.35), breast cancer-specific mortality (HR: 1.69; 95 %CI 1.07-2.68), and cancer recurrence (HR: 1.49; 95 %CI 0.99-2.25), compared to those in the lowest quintile (≤67 bpm). Moreover, every 10 bpm increase in RHR was associated with 15, 22, and 6 % increased risk of all-cause mortality, breast cancer-specific mortality, and cancer recurrence, respectively. However, the association between RHR and cancer recurrence was not statistically significant (p = 0.26). Elevated RHR was associated with an increased risk of mortality in patients with breast cancer. The findings from this study suggest that RHR may be used as a prognostic factor for patients with breast cancer in clinical settings. PMID:27544225

    The mortality experience of a cohort of chrysotile miners employed since 1946 in Balangero, northern Italy was updated to the end of 1987 giving a total of 427 deaths out of 27,010 man-years at risk. A substantial excess mortality for all causes (standardised mortality ratio (SMR) = 149) was found, mainly because of high rates for some alcohol related deaths (hepatic cirrhosis, accidents). For mortality from cancer, however, the number of observed deaths (82) was close to that expected (76.2). The SMR was raised for oral cancer (SMR 231 based on six deaths), cancer of the larynx (SMR 267 based on eight deaths), and pleura (SMR 667 based on two deaths), although the excess only reached statistical significance for cancer of the larynx. Rates were not increased for lung, stomach, or any other type of cancer. No consistent association was seen with duration or cumulative dust exposure (fibre-years) for oral cancer, but the greatest risks for laryngeal and pleural cancer were in the highest category of duration and degree of exposure to fibres. Although part of the excess mortality from laryngeal cancer is probably attributable to high alcohol consumption in this group of workers, the data suggest that exposure to chrysotile asbestos (or to the fibre balangeroite that accounts for 0.2-0.5% of total mass in the mine) is associated with some, however moderate, excess risk of laryngeal cancer and pleural mesothelioma. The absence of excess mortality from lung cancer in this cohort is difficult to interpret. Images PMID:2176805

    Post-operative mortality from colorectal cancer depends on multiple factors and varies across countries and hospitals. Pre-operative risk prediction can be helpful in surgical decision-making. Several scoring systems have been developed to predict the risk of post-operative mortality. The Portsmouth Physiological and Operative Severity Score for the enUmeration of Mortality (P-POSSUM) model and a revised Association of Colo-proctology of Great Britan and Ireland (ACPGBI) model are the most accurate predictors in colorectal cancer surgery. No scoring systems have been validated in the Danish population. PMID:25786698

  19. New findings for maternal mortality age patterns: aggregated results for 38 countries.

    Directory of Open Access Journals (Sweden)

    Ann K Blanc

    Full Text Available BACKGROUND: With recent results showing a global decline in overall maternal mortality during the last two decades and with the target date for achieving the Millennium Development Goals only four years away, the question of how to continue or even accelerate the decline has become more pressing. By knowing where the risk is highest as well as where the numbers of deaths are greatest, it may be possible to re-direct resources and fine-tune strategies for greater effectiveness in efforts to reduce maternal mortality. METHODS: We aggregate data from 38 Demographic and Health Surveys that included a maternal mortality module and were conducted in 2000 or later to produce maternal mortality ratios, rates, and numbers of deaths by five year age groups, separately by residence, region, and overall mortality level. FINDINGS: The age pattern of maternal mortality is broadly similar across regions, type of place of residence, and overall level of maternal mortality. A "J" shaped curve, with markedly higher risk after age 30, is evident in all groups. We find that the excess risk among adolescents is of a much lower magnitude than is generally assumed. The oldest age groups appear to be especially resistant to change. We also find evidence of extremely elevated risk among older mothers in countries with high levels of HIV prevalence. CONCLUSIONS: The largest number of deaths occurs in the age groups from 20-34, largely because those are the ages at which women are most likely to give birth so efforts directed at this group would most effectively reduce the number of deaths. Yet equity considerations suggest that efforts also be directed toward those most at risk, i.e., older women and adolescents. Because women are at risk each time they become pregnant, fulfilling the substantial unmet need for contraception is a cross-cutting strategy that can address both effectiveness and equity concerns.

    Full Text Available Abstract Background The aging of the Italian population will unavoidably lead to a growing number of persons diagnosed and living with cancer. A comprehensive description of the burden of cancer mortality among Italian elderly (65-84 years of age in the last four decades has not been carried out yet. Cancer mortality rates were used to describe time trends between 1970-2008. Methods Mortality counts, provided by the Italian National Institute of Statistics, were grouped according to data availability: in quinquennia from 1970-74 through 1995-99, and in 2000-03 and 2006-08 groups. Age-standardized rates (world population were computed by calendar periods while annual percent changes (APCs were computed for elderly and middle aged (35-64 years people for the period 1995-2008. Results The number of cancer deaths in elderly nearly doubled between 1970-74 (31,400 deaths/year in men, and 24,000 in women and 2006-08 (63,000 deaths/year in men, and 42,000 in women. Overall cancer mortality rates peaked during the quinquennia 1985-89 and 1990-94 (about 1,500/100,000 in men and 680 in women and declined thereafter. Throughout 1995-2008 cancer mortality rates decreased by -1.6%/year in men and -0.9%/year in women. These decreases were mainly driven by cancers of the stomach, bladder, prostate, and lung (APC = -3.3%, -2.7%, -2.5%, -2.2%, respectively in men, and by cancers of the stomach, bladder, and breast (APC = -3.5%, -1.9%, -1.1%, respectively in women. Conversely, increases in mortality rates between 1995 and 2008 were recorded for lung cancer (APC = +0.6% in women, cutaneous melanoma (APC = +1.7% in men, and pancreatic cancer (APC = +0.6% in men and +0.9% in women. Conclusions Overall favorable trends in cancer mortality were observed among Italian elderly between 1995 and 2008. Early diagnosis, improved efficacy of anti-cancer treatments and management of comorbidities are the most likely explanations of these positive

    We previously investigated bladder cancer risk in a cohort of dyestuff workers who were heavily exposed to aromatic amines from 1922 through 1972. We updated the follow-up by 14 years (through 2003) for 590 exposed workers to include more than 30 years of follow-up since last exposure to aromatic amines. Expected numbers of deaths from bladder cancer and other causes were computed by use of national mortality rates from 1951 to 1980 and regional mortality rates subsequently. There were 394 deaths, compared with 262.7 expected (standardized mortality ratio = 1.50, 95% confidence interval = 1.36 to 1.66). Overall, 56 deaths from bladder cancer were observed, compared with 3.4 expected (standardized mortality ratio = 16.5, 95% confidence interval = 12.4 to 21.4). The standardized mortality ratio for bladder cancer increased with younger age at first exposure and increasing duration of exposure. Although the standardized mortality ratio for bladder cancer steadily decreased with time since exposure stopped, the absolute risk remained approximately constant at 3.5 deaths per 1000 man-years up to 29 years after exposure stopped. Excess risk was apparent 30 years or more after last exposure. PMID:20548022

    Full Text Available Background. Worldwide, gastric cancer is the fourth leading cause of diseases, and the second leading cause of cancer deaths. Aim. To analyze the differences between men and women in mortality rate of gastric cancer in Belgrade from 1990−2002. Methods. Mortality rates standardized directly to the „World population“, and regression analysis were used. Results. In Belgrade population, 29.2% out the total number of deaths attributable to cancer were caused by gastric cancer. Gastric cancer was the second most common cause of death among digestive tract cancers. In women, in the period between 1990 and 1993, an average annual decline of mortality was 9.0% (95% confidence interval (CI = 5.9−13.1, and between 1994 and 2002, an average annual increase was 10.3% (CI = 8.4−12.6. Mortality rate series of gastric cancer in men did not fit any of the usual trend functions. The male/female gastric cancer mortality ratio was 1.7 : 1. Mortality rates for gastric cancer rose with age in both sexes and they were highest in the age group of 70 and more years. From 1990−2002, in both sexes aged 70 years and more, mortality from gastric cancer rose by 67.2% (CI = 58.0−76.4 in men and by 69.6% (CI = 60.6−78.6 in women. During the same period, the death rates in men decreased by 75.9 % (CI = 67.5−84.4 in the age group of 30−39 years, and by 48.1% (CI = 38.4−57.9 in women aged 50−59 years. In both sexes mortality rate series of all other age groups did not fit any of the usual trend functions. Conclusions. The increase in mortality rate of gastric in women over the past few years, showed the necessity of instituting primary and secondary preventive measures.

  5. Social determinants of Black-White disparities in breast cancer mortality: a review.

    Despite the recent decline in breast cancer mortality, African American women continue to die from breast cancer at higher rates than do White women. Beyond the fact that breast cancer tends to be a more biologically aggressive disease in African American than in White women, this disparity in breast cancer mortality also reflects social barriers that disproportionately affect African American women. These barriers hinder cancer prevention and control efforts and modify the biological expression of disease. The present review focuses on delineating social, economic, and cultural factors that are potentially responsible for Black-White disparities in breast cancer mortality. This review was guided by the social determinants of health disparities model, a model that identifies barriers associated with poverty, culture, and social injustice as major causes of health disparities. These barriers, in concert with genetic, biological, and environmental factors, can promote differential outcomes for African American and White women along the entire breast cancer continuum, from screening and early detection to treatment and survival. Barriers related to poverty include lack of a primary care physician, inadequate health insurance, and poor access to health care. Barriers related to culture include perceived invulnerability, folk beliefs, and a general mistrust of the health care system. Barriers related to social injustice include racial profiling and discrimination. Many of these barriers are potentially modifiable. Thus, in addition to biomedical advancements, future efforts to reduce disparities in breast cancer mortality should address social barriers that perpetuate disparities among African American and White women in the United States.

    Simultaneous screening with a blood test for the biomarker CA-125 along with a transvaginal ultrasound (TVU), compared with usual care, did not reduce ovarian cancer mortality in American women. These results, from a National Cancer Institute (NCI) sponsored trial, also show that diagnostic evaluation following a false-positive result was associated with potentially harmful complications.

    Full Text Available Abstract Background The literature suggests that the distribution of female breast cancer mortality demonstrates spatial concentration. There remains a lack of studies on how the mortality burden may impact racial groups across space and over time. The present study evaluated the geographic variations in breast cancer mortality in Texas females according to three predominant racial groups (non-Hispanic White, Black, and Hispanic females over a twelve-year period. It sought to clarify whether the spatiotemporal trend might place an uneven burden on particular racial groups, and whether the excess trend has persisted into the current decade. Methods The Spatial Scan Statistic was employed to examine the geographic excess of breast cancer mortality by race in Texas counties between 1990 and 2001. The statistic was conducted with a scan window of a maximum of 90% of the study period and a spatial cluster size of 50% of the population at risk. The next scan was conducted with a purely spatial option to verify whether the excess mortality persisted further. Spatial queries were performed to locate the regions of excess mortality affecting multiple racial groups. Results The first scan identified 4 regions with breast cancer mortality excess in both non-Hispanic White and Hispanic female populations. The most likely excess mortality with a relative risk of 1.12 (p = 0.001 occurred between 1990 and 1996 for non-Hispanic Whites, including 42 Texas counties along Gulf Coast and Central Texas. For Hispanics, West Texas with a relative risk of 1.18 was the most probable region of excess mortality (p = 0.001. Results of the second scan were identical to the first. This suggested that the excess mortality might not persist to the present decade. Spatial queries found that 3 counties in Southeast and 9 counties in Central Texas had excess mortality involving multiple racial groups. Conclusion Spatiotemporal variations in breast cancer mortality affected racial

    Full Text Available Abstract Background Formation of cellular malignancy results from the disruption of fine tuned signaling homeostasis for proliferation, accompanied by mal-functional signals for differentiation, cell cycle and apoptosis. We wanted to observe central signaling characteristics on a global view of malignant cells which have evolved to selfishness and independence in comparison to their non-malignant counterparts that fulfill well defined tasks in their sample. Results We investigated the regulation of signaling networks with twenty microarray datasets from eleven different tumor types and their corresponding non-malignant tissue samples. Proteins were represented by their coding genes and regulatory distances were defined by correlating the gene-regulation between neighboring proteins in the network (high correlation = small distance. In cancer cells we observed shorter pathways, larger extension of the networks, a lower signaling frequency of central proteins and links and a higher information content of the network. Proteins of high signaling frequency were enriched with cancer mutations. These proteins showed motifs of regulatory integration in normal cells which was disrupted in tumor cells. Conclusion Our global analysis revealed a distinct formation of signaling-regulation in cancer cells when compared to cells of normal samples. From these cancer-specific regulation patterns novel signaling motifs are proposed.

  12. Using mortality data to estimate radiation effects on breast cancer incidence

    International Nuclear Information System (INIS)

    In this paper we combine Japanese data on radiation exposure and cancer mortality with U.S. data on cancer incidence and lethality to estimate the effects of ionizing radiation on cancer incidence. The analysis is based on the mathematical relationship between the mortality rate and the incidence and lethality rates, as well as on statistical models that relate Japanese incidence rates to U.S. incidence rates and radiation risk factors. Our approach assumes that the risk of death from causes other than the cancer does not depend on whether or not the cancer is present, and among individuals with the cancer, the risk of death attributable to the cancer is the same in Japan and the U.S. and is not affected by radiation exposure. In particular, we focus on the incidence of breast cancer in Japanese women and how this incidence is affected by radiation risk factors. The analysis uses Japanese exposure and mortality data from the Radiation Effects Research Foundation study of atomic bomb survivors and U.S. incidence and lethality data from the Surveillance, Epidemiology, and End Results Registry. Even without Japanese incidence data, we obtain reasonable estimates of the incidence of breast cancer in unexposed Japanese women and identify the radiation risk factors that affect this incidence. Our analysis demonstrates that the age at exposure is an important risk factor, but that the incidence of breast cancer is not affected by the city of residence (Nagasaki versus Hiroshima) or the time since exposure

    Cancer surveillance data are collected every year in the United States via the National Program of Cancer Registries (NPCR) and the Surveillance, Epidemiology and End Results (SEER) Program of the National Cancer Institute (NCI). General trends are closely monitored to measure the nation's progress against cancer. The objective of this study was to apply a novel web informatics approach for enabling fully automated monitoring of cancer mortality trends. The approach involves automated collection and text mining of online obituaries to derive the age distribution, geospatial, and temporal trends of cancer deaths in the US. Using breast and lung cancer as examples, we mined 23,850 cancer-related and 413,024 general online obituaries spanning the timeframe 2008-2012. There was high correlation between the web-derived mortality trends and the official surveillance statistics reported by NCI with respect to the age distribution (ρ=0.981 for breast; ρ=0.994 for lung), the geospatial distribution (ρ=0.939 for breast; ρ=0.881 for lung), and the annual rates of cancer deaths (ρ=0.661 for breast; ρ=0.839 for lung). Additional experiments investigated the effect of sample size on the consistency of the web-based findings. Overall, our study findings support web informatics as a promising, cost-effective way to dynamically monitor spatiotemporal cancer mortality trends. PMID:27044930

    In 2010, cancer deaths accounted for more than 15% of all deaths worldwide, and this fraction is estimated to rise in the coming years. Increased cancer mortality has been observed in immigrant populations, but a comprehensive analysis by country of birth has not been conducted. We followed all individuals living in Sweden between 1961 and 2009 (7,109,327 men and 6,958,714 women), and calculated crude cancer mortality rates and age-standardized rates (ASRs) using the world population for stan...

  17. Patterns of Excess Cancer Risk among the Atomic Bomb Survivors

    Pierce, Donald A.

    1996-05-01

    I will indicate the major epidemiological findings regarding excess cancer among the atomic-bomb survivors, with some special attention to what can be said about low-dose risks. This will be based on 1950--90 mortality follow-up of about 87,000 survivors having individual radiation dose estimates. Of these about 50,000 had doses greater than 0.005 Sv, and the remainder serve largely as a comparison group. It is estimated that for this cohort there have been about 400 excess cancer deaths among a total of about 7800. Since there are about 37,000 subjects in the dose range .005--.20 Sv, there is substantial low-dose information in this study. The person-year-Seivert for the dose range under .20 Sv is greater than for any one of the 6 study cohorts of U.S., Canadian, and U.K. nuclear workers; and is equal to about 60% of the total for the combined cohorts. It is estimated, without linear extrapolation from higher doses, that for the RERF cohort there have been about 100 excess cancer deaths in the dose range under .20 Sv. Both the dose-response and age-time patterns of excess risk are very different for solid cancers and leukemia. One of the most important findings has been that the solid cancer (absolute) excess risk has steadily increased over the entire follow-up to date, similarly to the age-increase of the background risk. About 25% of the excess solid cancer deaths occurred in the last 5 years of the 1950--90 follow-up. On the contrary most of the excess leukemia risk occurred in the first few years following exposure. The observed dose response for solid cancers is very linear up to about 3 Sv, whereas for leukemia there is statistically significant upward curvature on that range. Very little has been proposed to explain this distinction. Although there is no hint of upward curvature or a threshold for solid cancers, the inherent difficulty of precisely estimating very small risks along with radiobiological observations that many radiation effects are nonlinear

  18. Impact of Forest Fragmentation on Patterns of Mountain Pine Beetle-Caused Tree Mortality

    Directory of Open Access Journals (Sweden)

    Trisalyn A. Nelson

    2013-04-01

    Full Text Available The current outbreak of mountain pine beetle, Dendroctonus ponderosae Hopkins, has led to extensive tree mortality in British Columbia and the western United States. While the greatest impacts of the outbreak have been in British Columbia, ongoing impacts are expected as the outbreak continues to spread eastward towards Canada’s boreal and eastern pine forests. Successful mitigation of this outbreak is dependent on understanding how the beetle’s host selection behaviour is influenced by the patchwork of tree mortality across the landscape. While several studies have shown that selective mechanisms operate at the individual tree level, less attention has been given to beetles’ preference for variation in spatial forest patterns, namely forest fragmentation, and if such preference changes with changing population conditions. The objective of this study is to explore the influence of fragmentation on the location of mountain pine beetle caused mortality. Using a negative binomial regression model, we tested the significance of a fragmentation measure called the Aggregation Index for predicting beetle-caused tree mortality in the central interior of British Columbia, Canada in 2000 and 2005. The results explain that mountain pine beetle OPEN ACCESS Forests 2013, 4 280 exhibit a density-dependent dynamic behaviour related to forest patterns, with fragmented forests experiencing greater tree mortality when beetle populations are low (2000. Conversely, more contiguous forests are preferred when populations reach epidemic levels (2005. These results reinforce existing findings that bark beetles exhibit a strong host configuration preference at low population levels and that such pressures are relaxed when beetle densities are high.

  19. Cancer mortality in the commune of Pargny sur Saulx in France

    International Nuclear Information System (INIS)

    Radioactive thorium wastes were found in April 1997 at the former industrial site of 'Orflam-Plast' in the commune of Pargny sur Saulx in the Northeast of France, where industrial activity began in 1934. On this site, between 1934 and 1970, cerium for lighter stones and thorium nitrate were extracted from imported monazite sand, a mineral containing elevated levels of natural radioactivity. We decided to study cancer mortality in the surrounding population. We found an excess of mortality due to lung and bladder cancer in the commune of Pargny sur Saulx and its neighbours, between 1968 and 1994. This excess did not seem to be linked to the river of Saulx which was a possible source of contamination. We conclude that a cancer incidence study of the former workers of this industrial site is necessary in order to investigate the role of natural radioactivity from monazite processing in the risk of cancer mortality among this workforce.

    The Radiation Effects Research Foundation has recently implemented a new dosimetry system, DS02, to replace the previous system, DS86. This paper assesses the effect of the change on risk estimates for radiation-related solid cancer and leukemia mortality. The changes in dose estimates were smaller than many had anticipated, with the primary systematic change being an increase of about 10% in gamma-ray estimates for both cities. In particular, an anticipated large increase of the neutron component in Hiroshima for low-dose survivors did not materialize. However, DS02 improves on DS86 in many details, including the specifics of the radiation released by the bombs and the effects of shielding by structures and terrain. The data used here extend the last reported follow-up for solid cancers by 3 years, with a total of 10,085 deaths, and extends the follow-up for leukemia by 10 years, with a total of 296 deaths. For both solid cancer and leukemia, estimated age-time patterns and sex difference are virtually unchanged by the dosimetry revision. The estimates of solid-cancer radiation risk per sievert and the curvilinear dose response for leukemia are both decreased by about 8% by the dosimetry revision, due to the increase in the gamma-ray dose estimates. The apparent shape of the dose response is virtually unchanged by the dosimetry revision, but for solid cancers, the additional 3 years of follow-up has some effect. In particular, there is for the first time a statistically significant upward curvature for solid cancer on the restricted dose range 0-2 Sv. However, the low-dose slope of a linear-quadratic fit to that dose range should probably not be relied on for risk estimation, since that is substantially smaller than the linear slopes on ranges 0-1 Sv, 0-0.5 Sv, and 0- 0.25 Sv. Although it was anticipated that the new dosimetry system might reduce some apparent dose overestimates for Nagasaki factory workers, this did not materialize, and factory workers have

    AIM: To analyze the data from Tianjin Cancer Registry of morality due to colon cancer from 1981 to 2000 in Tianjin,China.METHODS: Tumors diagnosed in this study were coded according to ICD-9. Mortality rates were calculated by sex and calendar year of diagnosis.RESULTS: Seventy point four percent of colon cancer deaths occurred in the age group of 55-79 years and the mortality rate reached its peak in the age group of 75-80 years.The average age at death was 64.10 years. An ascending trend was observed in the mean age of death due to colon cancer from 1981 through 2000. However, as for the sex ratio, there was no clear trend exhibited. During 1981-2000, the total number of deaths was 2147, 1041males and 1106 females. The mean mortality rate of colon cancer was 3.04/100 000. The mortality caused by colon cancer ascended from 1981 to 2000.CONCLUSION: The epidenic trend of colon cancer in Tianjin and its risk factors and prevention should be studied further.

    The mammography screening trials have shown varying results. This could be because screening was better in some trials than in others at advancing the time of diagnosis. If so, more cancers would be identified in such trials relative to the control group, and fewer of the cancers would have reached...... an advanced stage. I performed a systematic review of the mammography screening trials using metaregression. Finding many cancers was not related to the size of the reduction in breast cancer mortality (p = 0.19 after seven and p = 0.73 after 13 years of follow-up). In contrast, finding few cancers...

    Full Text Available Abstract Background To compare the characteristics and prognostic features of ischemic stroke in patients with diabetes and without diabetes, and to determine the independent predictors of in-hospital mortality in people with diabetes and ischemic stroke. Methods Diabetes was diagnosed in 393 (21.3% of 1,840 consecutive patients with cerebral infarction included in a prospective stroke registry over a 12-year period. Demographic characteristics, cardiovascular risk factors, clinical events, stroke subtypes, neuroimaging data, and outcome in ischemic stroke patients with and without diabetes were compared. Predictors of in-hospital mortality in diabetic patients with ischemic stroke were assessed by multivariate analysis. Results People with diabetes compared to people without diabetes presented more frequently atherothrombotic stroke (41.2% vs 27% and lacunar infarction (35.1% vs 23.9% (P P = NS. Ischemic heart disease, hyperlipidemia, subacute onset, 85 years old or more, atherothrombotic and lacunar infarcts, and thalamic topography were independently associated with ischemic stroke in patients with diabetes, whereas predictors of in-hospital mortality included the patient's age, decreased consciousness, chronic nephropathy, congestive heart failure and atrial fibrillation Conclusion Ischemic stroke in people with diabetes showed a different clinical pattern from those without diabetes, with atherothrombotic stroke and lacunar infarcts being more frequent. Clinical factors indicative of the severity of ischemic stroke available at onset have a predominant influence upon in-hospital mortality and may help clinicians to assess prognosis more accurately.

  9. Patterns of care study and evidence based medicine for radiation therapy. Prostate cancer

    International Nuclear Information System (INIS)

    In Japan, where the mortality rate of prostate cancer is lower than in Western countries, there is little evidence of radiation therapy for prostate cancer. Therefore, we have to refer to the evidence of radiation therapy from Western countries, but we should pay attention to the differences of cultural, racial, or social background between Japan and Western countries. The Patterns of Care Study (PCS) was conducted in Japan and extramural audits were performed for 50 randomly selected institutions. Detailed information of 311 prostate cancer patients without distant metastases and other cancers, who were treated with radiation therapy in 1996-1998, was collected. In this article, the results of PCS for primary prostate cancer were shown, with a review of literature for the appropriate choice of radiation therapy. This study was supported by the Grantin-Aid for Cancer Research from Ministry of Health, Labor and Welfare (10-17). (author)

    2011-04-01

    Full Text Available Abstract Background Cancer remains a major cause of morbidity and mortality worldwide. In developing countries, data on lung cancer mortality are scarce. Methods Using South Africa's annual mortality and population estimates data, we calculated lung cancer age-standardised mortality rates for the period 1995 to 2006. The WHO world standard population was used as the reference population. Scatter plots and regression models were used to assess linear trends in mortality rates. To better characterise emerging trends, regression models were also partitioned for defined periods. Results Lung cancer caused 52,217 deaths during the study period. There were 4,525 deaths for the most recent year (2006, with men accounting for 67% of deaths. For the entire South African population, the age-standardised mortality rate of 24.3 per 100,000 persons in 1995 was similar to the rate of 23.8 per 100,000 persons in 2006. Overall, there was no significant decline in lung cancer mortality in South Africa from 1995 to 2006 (slope = -0.15, p = 0.923. In men, there was a statistically non-significant annual decline of 0.21 deaths per 100,000 persons (p = 0.433 for the study period. However, from 2001 to 2006, the annual decline of 1.29 deaths per 100,000 persons was statistically significant (p = 0.009. In women, the mortality rate increased significantly at an annual rate of 0.19 per 100,000 persons (p = 0.043 for the study period, and at a higher rate of 0.34 per 100,000 persons (p = 0.007 from 1999 to 2006. Conclusion The more recent declining lung cancer mortality rate in men is welcome but the increasing rate in women is a public health concern that warrants intervention. Smoking intervention policies and programmes need to be strengthened to further reduce lung cancer mortality in men and to address the increasing rates in women.

    Domestic fuel combustion from cooking and heating, to which about 3 billion people worldwide are exposed, is associated with increased lung cancer risk. Lung cancer incidence in Xuanwei is the highest in China, and the attributable risk of lung cancer from unvented smoky coal burning is greater than 90%. To evaluate any lung cancer mortality reduction after changing from unvented stoves to portable stoves, we used lifetime smoky coal users in a retrospective cohort of all farmers born during 1917-1951 and residing in Xuanwei in 1976. Of the 42 422 enrolled farmers, 4054 lifetime smoky coal users changed to portable stoves, 4364 did not change, and 1074 died of lung cancer. Lung cancer morality associated with stove change was assessed by product-limit survival curves and multivariate Cox regression models. Both men (P < 0.0001) and women (P < 0.0001) who changed to portable stoves had a significantly increased probability of survival compared with those who did not change. Portable stoves were associated with decreased risk of lung cancer mortality in male participants (hazard ratio (HR) 0.62, 95% confidence interval (CI) 0.46-0.82) and female participants (HR 0.41, 95% CI 0.29-0.57). Portable stove use is associated with reduced lung cancer mortality risk, highlighting a cost-effective intervention that could substantially benefit health in developing countries.

  15. Age and sex pattern of cardiovascular mortality, hospitalisation and associated cost in India.

    Full Text Available CONTEXT: Though the cardiovascular diseases are the leading cause of mortality in India, little is known about the human and economic loss attributed to the disease. The aim of this paper is to account the age and sex pattern of mortality, hospitalisation and the cost of hospitalisation for cardiovascular diseases in India. DATA AND METHODS: Data for the present study has been drawn from multiple sources; 52(nd and 60(th rounds of the National Sample Survey, Special Survey of Death, 2001-03 and the Sample Registration System 2004-2010. Under the changing demographics and constant assumptions of mortality, hospitalisation and cost of hospitalisation, we have estimated the deaths, hospitalisation and cost of hospitalisation for cardiovascular diseases in India during 2004 to 2021. Descriptive analyses and multivariate techniques were used to understand the socio-economic differentials in cost of hospitalisation for cardiovascular diseases in India. FINDINGS: In India, the cardiovascular diseases accounted for an estimated 1.4 million deaths in 2004 and it is likely to be 2.1 million in 2021. An estimated 6.7 million people were hospitalised for cardiovascular diseases in 2004, and projected to be 10.9 million by 2021. Unlike mortality, majority of the hospitalisation due to cardiovascular diseases will be in the prime working age group (25-59. The estimated cost of hospitalisation for cardiovascular diseases was 94/- billion rupees in 2004 and expected to be 152/- billion rupees by 2021, at 2004 prices. The cost of hospitalisation for cardiovascular diseases was significantly high in private health centres, high fertility states and among high socio-economic groups. CONCLUSION: The cardiovascular mortality and hospitalisation will be largely concentrated in the prime working age group and the cost of hospitalisation is expected to increase substantially in coming years. This calls for mobilising resources, increasing access to health insurance and

    Full Text Available

    Background: Esophageal cancer (EC is one of the most common cancers worldwide. Mortality is a familiar projection that addresses the burden of cancers. With regards to cancer mortality, data are important and used to monitor the effects of screening programs, earlier diagnosis and other prognostic factors. But according to the Iranian death registry, about 20% of death statistics are still recorded in misclassified categories. The aim of this study is to estimate EC mortality in the Iranian population, using a Bayesian approach in order to revise this misclassification.

    Methods: We analyzed National death Statistics reported by the Iranian Ministry of Health and Medical Education from 1995 to 2004. ECs [ICD-9; C15] were expressed as annual mortality rates/100,000, overall, by sex, by age group and age standardized rate (ASR. The Bayesian approach was used to correct and account for misclassification effects in Poisson count regression, with a beta prior employed to estimate the mortality rate of EC in age and sex groups.

    Results: According to the Bayesian analysis, there were between 20 to 30 percent underreported deaths in mortality records related to EC, and the rate of mortality from EC has increased through recent years.

    Conclusions: Our findings suggested a substantial undercount of EC mortality in the Iranian population. So
    policy makers who determine research and treatment priorities based on reported death rates should notice of this underreported data.

    BACKGROUND: In 1987, investigators in Liaoning Province, China, reported that mortality rates for all cancer, stomach cancer, and lung cancer in 1970-1978 were higher in villages with hexavalent chromium (Cr)-contaminated drinking water than in the general population. The investigators reported rates, but did not report statistical measures of association or precision. METHODS: Using reports and other communications from investigators at the local Jinzhou Health and Anti-Epidemic Station, we obtained data on Cr contamination of groundwater and cancer mortality in 9 study regions near a ferrochromium factory. We estimated:(1) person-years at risk in the study regions, based on census and population growth rate data, (2) mortality counts, based on estimated person-years at risk and previously reported mortality rates, and (3) rate ratios and 95% confidence intervals. RESULTS: The all-cancer mortality rate in the combined 5 study regions with Cr-contaminated water was negligibly elevated in comparison with the rate in the 4 combined study regions without contaminated water (rate ratio = 1.13; 95% confidence interval = 0.86-1.46), but was somewhat more elevated in comparison with the whole province (1.23; 0.97-1.53). Stomach cancer mortality in the regions with contaminated water was more substantially elevated in comparison with the regions without contaminated water (1.82; 1.11-2.91) and the whole province (1.69; 1.12-2.44). Lung cancer mortality was slightly elevated in comparison with the unexposed study regions (1.15; 0.62-2.07), and more strongly elevated in comparison with the whole province (1.78; 1.03-2.87). Mortality from other cancers combined was not elevated in comparison with either the unexposed study regions (0.86; 0.53-1.36) or the whole province (0.92; 0.58-1.38). CONCLUSIONS: While these data are limited, they are consistent with increased stomach cancer risk in a population exposed to Cr in drinking water. ?? 2008 Lippincott Williams & Wilkins, Inc.

    Treatment choice for localized prostate cancer (PCa) is a controversial issue, and mortality risk is probably the most decisive factor in this regard. The study aimed to compare prostate-cancer-specific mortality risk estimates for different treatment options assigned by patients managed with active surveillance (AS), radical prostatectomy (RP) and patients who had discontinued AS (DAS). Patients initially managed with AS or RP (N = 370) were matched according to length of therapy. All patients completed mailed questionnaires assessing their mortality risk estimates (in %) and prostate-cancer-specific anxiety. Differences in risk estimates among the three treatment groups were analyzed using ANOVA, relationships of clinical and psychosocial variables with risk estimates using standard multiple regression. In all treatment groups, the prostate- cancer-specific mortality risk was overestimated. This applied whether it was the patient's own treatment or the alternative treatment option. RP patients assigned a mortality risk to AS that was almost three times higher than that assigned to RP (50.9 ± 25.0 vs. 17.8 ± 19.7, d = 1.48; p risk estimates for AS (p = 0.008) and RP (p = 0.001). Compared with clinical data that suggest that the prostate-cancer-specific mortality risk for AS is low and does not significantly differ from that for RP, patients strongly overestimated the mortality risk. This was most markedly so in RP patients, who drastically overestimated the benefits of RP compared to the risk of AS. This overestimation could increase overtreatment and should therefore be corrected by better patient education. PMID:27038059

  1. Lung cancer mortality among nonsmoking uranium miners exposed to radon daughters

    International Nuclear Information System (INIS)

    Radon daughters, both in the workplace and in the household, are a continuing cause for concern because of the well-documented association between exposure to radon daughters and lung cancer. To estimate the risk of lung cancer mortality among nonsmokers exposed to varying levels of radon daughters, 516 white men who never smoked cigarettes, pipes, or cigars were selected from the US Public Health Service cohort of Colorado Plateau uranium miners and followed up from 1950 through 1984. Age-specific mortality rates for nonsmokers from a study of US veterans were used for comparison. Fourteen deaths from lung cancer were observed among the nonsmoking miners, while 1.1 deaths were expected, yielding a standardized mortality ratio of 12.7 with 95% confidence limits of 8.0 and 20.1. These results confirm that exposure to radon daughters in the absence of cigarette smoking is a potent carcinogen that should be strictly controlled

  2. Evaluation of fallout strontium-90 accumulation in bone and cancer mortality risk in Japanese

    International Nuclear Information System (INIS)

    The mathematical model was developed for evaluating a fallout 90Sr accumulation in Japanese bone through its dietary intake, and was validated by comparing the estimates of 90Sr concentration in bone with the observed. The mortality risk by the radiation-induced leukemia and bone cancer was evaluated based on the NUREG/CR-4214 model. The main results obtained in this study under the limited assumptions are as follows: (1) The mathematical model was developed to relate 90Sr concentration in an environment with the mortality risk due to the radiation-induced leukemia and bone cancer through dietary intake of fallout 90Sr. (2) The leukemia mortality risk due to the fallout 90Sr is about one order larger than the bone cancer mortality risk, and is evaluated to be larger than 10-6 for Japanese who were born before early 1970's. (3) The leukemia mortality risk due to the fallout 90Sr is about 10% level in 1992 of the leukemia mortality risk expected by the benzene in ambient air. (author)

    2015-09-01

    The objectives were to analyze lung cancer mortality trends in Chile from 1990 to 2009, and to project the rates six years forward. Lung cancer mortality data were obtained from the Chilean Ministry of Health. To obtain mortality rates, population projections were used, based on the 2002 National Census. Rates were adjusted using the world standard population as reference. Bayesian dynamic linear models were fitted to estimate trends from 1990 to 2009 and to obtain projections for 2010-2015. During the period under study, there was a 19.9% reduction in the lung cancer mortality rate in men. In women, there was increase of 28.4%. The second-order model showed a better fit for men, and the first-order model a better fit for women. Between 2010 and 2015 the downward trend continued in men, while a trend to stabilization was projected for lung cancer mortality in women in Chile. This analytical approach could be useful implement surveillance systems for chronic non-communicable disease and to evaluate preventive strategies. PMID:26578021

  7. Waiting list paradox: Danish cancer patients diagnosed fast have higher mortality after diagnosis

    DEFF Research Database (Denmark)

    Tørring, Marie Louise; Frydenberg, Morten; Hansen, Rikke Pilegaard;

    Studies often show that cancer patients diagnosed more rapidly have higher mortality rates than patients with longer waits in the primary and secondary health care sector. Our aim was to examine whether this paradox is manifest in the Danish health care system. The study was based on data on...... with longer diagnostic interval until the reference point of 30 days. For colon, rectal, skin, and breast cancer mortality seemed to increase with diagnostic interval longer than 30 days. The waiting list paradox is manifest in Denmark.

    Full Text Available BACKGROUND: Leisure time physical activity has been extensively studied. However, the health benefits of non-leisure time physical activity, particular those undertaken at home on all-cause and cancer mortality are limited, particularly among the elderly. METHODS: We studied physical activity in relation to all-cause and cancer mortality in a cohort of 4,000 community-dwelling elderly aged 65 and older. Leisure time physical activity (sport/recreational activity and lawn work/yard care/gardening and non-leisure time physical activity (housework, home repairs and caring for another person were self-reported on the Physical Activity Scale for the Elderly. Subjects with heart diseases, stroke, cancer or diabetes at baseline were excluded (n = 1,133. RESULTS: Among the 2,867 subjects with a mean age of 72 years at baseline, 452 died from all-cause and 185 died from cancer during the follow-up period (2001-2012. With the adjustment for age, education level and lifestyle factors, we found an inverse association between risk of all-cause mortality and heavy housework among men, with the adjusted hazard ratio (HR of 0.72 (95%CI = 0.57-0.92. Further adjustment for BMI, frailty index, living arrangement, and leisure time activity did not change the result (HR = 0.71, 95%CI = 0.56-0.91. Among women, however, heavy housework was not associated with all-cause mortality. The risk of cancer mortality was significantly lower among men who participated in heavy housework (HR = 0.52, 95%CI = 0.35-0.78, whereas among women the risk was not significant. Men participated in light housework also were at lower risk of cancer mortality than were their counterparts, however, the association was not significant. Leisure time physical activity was not related to all-cause or cancer mortality in either men or women. CONCLUSION: Heavy housework is associated with reduced mortality and cancer deaths over a 9-year period. The underlying mechanism needs

    International Nuclear Information System (INIS)

    Selenium status in male and female Canadian subjects was measured relative to cancer mortality in their respective provinces. Toenail specimens from 755 subjects, 377 males and 378 females, living in Vancouver (186), Edmonton (188), Toronto (197) and Montreal (184) were analyzed by instrumental neutron activation analysis giving means of 0.968 ± 0.177, 0.950 ± 0.148, 0.932 ± 0.135 and 0.896 ± 0.127 ppm Se, respectively. The effect of selenium determinants such as gender, selenium supplementation and smoking on selenium status is presented. Details of the observed inverse relationship of selenium status and cancer mortality are discussed. (author)

  12. Lung cancer mortality and indoor radon concentrations in 18 Canadian cities

    International Nuclear Information System (INIS)

    Indoor radon and radon daughter concentrations were measured in a survey of 14,000 homes in 18 Canadian cities conducted in the summers of 1978 through 1980. Mortality and population data for the period 1966 through 1979 were retrieved for the geographic areas surveyed in each city. The results of analysis of the relation between lung cancer and radon daughter concentration, smoking habits and socioeconomic indicators for each city showed no detectable association between radon daughter concentrations and lung cancer mortality rates with or without adjustment for differences in smoking habits between cities

    2011-12-01

    We explored the association between neighborhood residential racial composition and breast cancer mortality among Black and White breast cancer patients in Georgia and whether spatial access to cancer care mediates this association. Participants included 15,256 women living in 15 metropolitan statistical areas in Georgia who were diagnosed with breast cancer between 1999 and 2003. Residential racial composition was operationalized as the percent of Black residents in the census tract. We used gravity-based modeling methods to ascertain spatial access to oncology care. Multilevel Cox proportional hazards models and mediation analyses were used to test associations. Black women were 1.5 times more likely to die from breast cancer than White women. Residential racial composition had a small but significant association with breast cancer mortality (hazard ratios [HRs] = 1.04-1.08 per 10% increase in the percent of Black tract residents). Individual race did not moderate this relationship, and spatial access to care did not mediate it. Residential racial composition may be part of the socioenvironmental milieu that produces increased breast cancer mortality among Black women. However, there is a lack of evidence that spatial access to oncology care mediates these processes. PMID:21847712

    Full Text Available Background: cancer is a major health problem due its high morbidity and mortality. It presents a major social challenge, since its incidence increases with economic and industrial development of the countries. Objectives: to characterize cancer mortality in Cruces in the decade 2002-2011 and to determine mortality rates per year. Methods: a retrospective descriptive study was conducted. The universe consisted of 530 patients who died of cancer in the interval indicated. Data were obtained through the Primary Register of Deaths of the Statistics Department in the municipality. The variables were: age, sex, place of death, primary cause of death and survival time for the disease. Results: male patients aged 73-90 years who died of lung cancer in 2006 predominated. The most frequent place of death was home. Time interval between diagnosis and time of death was several years. Conclusions: cancer is a major health problem for the population in Cruces, showing increasing levels of mortality mostly related to population aging.

  16. Spatial Analysis of County-Level Breast Cancer Mortality in Texas Arvin

    International Nuclear Information System (INIS)

    Objective. The objectives of the study were to detect high-risk areas and to examine how racial and ethnic status affect the geographic distribution of female breast cancer mortality in Texas. Analyses were based on county-level data for the years from 2000 to 2008. Materials and Methods. Breast cancer mortality data were obtained from the Texas Cancer Registry, and the Spatial Scan Statistics method was used to run Purely Spatial Analyses using the Discrete Poisson, Bernoulli, and Multinomial models. Results and Conclusions. Highest rates of female breast cancer mortality in Texas have shifted over time from southeastern areas towards northern and eastern areas, and breast cancer mortality at the county level is distributed heterogeneously based on racial/ethnic status. Non-Hispanic blacks were at highest risk in the northeastern region and lowest risk in the southern region, while Hispanics were at highest risk in the southern region along the border with Mexico and lowest risk in the northeastern region.

    Using a population-based cancer registry, Thuret et al. developed 3 nomograms for estimating cancer-specific mortality in men with penile squamous cell carcinoma. In the initial cohort, only 23.0% of the patients were treated with inguinal lymphadenectomy and had pN stage. To generalize the prediction models in clinical practice, we evaluated the performance of the 3 nomograms in a series of penile cancer patients who were treated with definitive surgery. Clinicopathologic information was obtained from 160 M0 penile cancer patients who underwent primary tumor excision and regional lymphadenectomy between 1990 and 2008. The predicted probabilities of cancer-specific mortality were calculated from 3 nomograms that were based on different disease stage definitions and tumor grade. Discrimination, calibration, and clinical usefulness were assessed to compare model performance. The discrimination ability was similar in nomograms using the TNM classification or American Joint Committee on Cancer staging (Harrell’s concordance index = 0.817 and 0.832, respectively), whereas it was inferior for the Surveillance, Epidemiology and End Results staging (Harrel ’s concordance index = 0.728). Better agreement with the observed cancer-specific mortality was shown for the model consisting of TNM classification and tumor grade, which also achieved favorable clinical net benefit, with a threshold probability in the range of 0 to 42%. The nomogram consisting of TNM classification and tumor grading was shown to have better performance for predicting cancer-specific mortality in penile cancer patients who underwent definitive surgery. Our data support the integration of this model in decision-making and trial design.

    2016-01-01

    Background Estimates of radiation-induced breast cancer risk from mammography screening have not previously considered dose exposure variation or diagnostic work-up after abnormal screening. Objective To estimate distributions of radiation-induced breast cancer incidence and mortality from digital mammography screening, considering exposure from screening and diagnostic mammography and dose variation across women. Design Two simulation-modeling approaches using common data on screening mammography from the Breast Cancer Surveillance Consortium and radiation dose from mammography from the Digital Mammographic Imaging Screening Trial. Setting U.S. population. Patients Women aged 40–74 years. Interventions Annual or biennial digital mammography screening from age 40, 45, or 50 until 74. Measurements Lifetime breast cancer deaths averted (benefits) and radiation-induced breast cancer incidence and mortality per 100,000 women screened (harms). Results On average, annual screening of 100,000 women aged 40 to 74 years was projected to induce 125 breast cancers (95% confidence interval [CI]=88–178) leading to 16 deaths (95% CI=11–23) relative to 968 breast cancer deaths averted by early detection from screening. Women exposed at the 95th percentile were projected to develop 246 radiation-induced breast cancers leading to 32 deaths per 100,000 women. Women with large breasts requiring extra views for complete breast examination (8% of population) were projected to have higher radiation-induced breast cancer incidence and mortality (266 cancers, 35 deaths per 100,000 women), compared to women with small or average breasts (113 cancers, 15 deaths per 100,000 women). Biennial screening starting at age 50 reduced risk of radiation-induced cancers 5-fold. Limitations We were unable to estimate years of life lost from radiation-induced breast cancer. Conclusions Radiation-induced breast cancer incidence and mortality from digital mammography screening are impacted by dose

The authors examined this association among 38,801 men ages 20 to 88 years who performed a maximal treadmill exercise test at baseline in the Aerobics Center Longitudinal Study (Dallas, TX) during 1974 to 2003. Mortality was assessed over 29 years of follow-up (1974-2003). Two hundred eighty-three digestive system cancer deaths occurred during a mean 17 years of observation. Age-adjusted mortality rates per 10,000 person-years according to low, moderate, and high CRF groups were 6.8, 4.0, and 3.3 for digestive system cancer (P(trend) < 0.001). After adjustment for age, examination year, body mass index, smoking, drinking, family history of cancer, personal history of diabetes, hazard ratios (95% confidence intervals) for overall digestive cancer deaths for those in the middle and upper 40% of the distribution of CRF relative to those in the lowest 20% were 0.66 (0.49-0.88) and 0.56 (0.40-0.80), respectively. Being fit (the upper 80% of CRF) was associated with a lower risk of mortality from colon [0.61 (0.37-1.00)], colorectal [0.58 (0.37-0.92)], and liver cancer [0.28 (0.11-0.72)] compared with being unfit (the lowest 20% of CRF). These findings support a protective role of CRF against total digestive tract, colorectal, and liver cancer deaths in men. PMID:19293313

    Although higher levels of physical activity are inversely associated with risk of colon cancer, few prospective studies have evaluated overall digestive system cancer mortality in relation to cardiorespiratory fitness (CRF). The authors examined this association among 38,801 men aged 20−88 years and who performed a maximal treadmill exercise test at baseline in the Aerobics Center Longitudinal Study (Dallas, Texas) during 1974−2003. Mortality was assessed over 29 years of follow-up (1974−2003). 283 digestive system cancer deaths occurred during a mean 17-year of observation. Age-adjusted mortality rates per 10,000 person-yrs according to low, moderate, and high CRF groups were 6.8, 4.0, and 3.3 for digestive system cancer (trend p < 0.001). After adjustment for age, examination year, body mass index, smoking, drinking, family history of cancer, personal history of diabetes, hazard ratios for overall digestive cancer deaths (95% confidence interval) for those in the middle and upper 40% of the distribution of CRF relative to those in the lowest 20% were 0.66 (0.49, 0.88) and 0.56 (0.40, 0.80), respectively. Being fit (the upper 80% of CRF) was associated with a lower risk of mortality from colon (0.61 [0.37, 1.00]), colorectal (0.58 [0.37, 0.92]), and liver cancer (0.28 [0.11, 0.72]), compared with being unfit (the lowest 20% of CRF). These findings support a protective role of CRF against total digestive tract, colorectal, and liver cancer deaths in men. PMID:19293313

    Full Text Available Context Several international studies have observed a correlation between the improvement of socio-demographic indicators and rates of incidence and mortality from cancer of the colon and rectum. Objective The objective of this study is to estimate the correlation between average per capita income and the rate of colorectal cancer mortality in Brazil between 2001 and 2009. Methods We obtained data on income inequality (Gini index, population with low incomes (½ infer the minimum wage/month, average family income, per capita ICP and mortality from colon cancer and straight between 2001-2009 by DATASUS. A trend analysis was performed using linear regression, and correlation between variables by Pearson's correlation coefficient. Results There was a declining trend in poverty and income inequality, and growth in ICP per capita and median family income and standardized mortality rate for colorectal cancer in Brazil. There was also strong positive correlation between mortality from this site of cancer and inequality (men r = -0.30, P = 0.06, women r = -0.33, P = 0.05 income low income (men r = -0.80, P<0.001, women r = -0.76, P<0.001, median family income (men r = 0.79, P = 0.06, women r = 0.76, P<0.001 and ICP per capita (men r = 0.73, P<0.001, women r = 0.68, P<0.001 throughout the study period. Conclusion The increase of income and reducing inequality may partially explain the increased occurrence of colorectal cancer and this is possibly due to differential access to food recognized as a risk factor, such as red meat and high in fat. It is important therefore to assess the priority of public health programs addressing nutrition in countries of intermediate economy, as is the case of Brazil.

  17. The influence of the CHIEF pathway on colorectal cancer-specific mortality.

    Directory of Open Access Journals (Sweden)

    Full Text Available Many components of the CHIEF (Convergence of Hormones, Inflammation, and Energy Related Factors pathway could influence survival given their involvement in cell growth, apoptosis, angiogenesis, and tumor invasion stimulation. We used ARTP (Adaptive Rank Truncation Product to test if genes in the pathway were associated with colorectal cancer-specific mortality. Colon cancer (n = 1555 and rectal cancer (n = 754 cases were followed over five years. Age, center, stage at diagnosis, and tumor molecular phenotype were considered when calculating ARTP p values. A polygenic risk score was used to summarize the magnitude of risk associated with this pathway. The JAK/STAT/SOC was significant for colon cancer survival (PARTP = 0.035. Fifteen genes (DUSP2, INFGR1, IL6, IRF2, JAK2, MAP3K10, MMP1, NFkB1A, NOS2A, PIK3CA, SEPX1, SMAD3, TLR2, TYK2, and VDR were associated with colon cancer mortality (PARTP < 0.05; JAK2 (PARTP  = 0.0086, PIK3CA (PARTP = 0.0098, and SMAD3 (PARTP = 0.0059 had the strongest associations. Over 40 SNPs were significantly associated with survival within the 15 significant genes (PARTP < 0.05. SMAD3 had the strongest association with survival (HRGG 2.46 95% CI 1.44,4.21 PTtrnd = 0.0002. Seven genes (IL2RA, IL8RA, IL8RB, IRF2, RAF1, RUNX3, and SEPX1 were significantly associated with rectal cancer (PARTP < 0.05. The HR for colorectal cancer-specific mortality among colon cancer cases in the upper at-risk alleles group was 11.81 (95% CI 7.07, 19. 74 and was 10.99 (95% CI 5.30, 22.78 for rectal cancer. These results suggest that several genes in the CHIEF pathway are important for colorectal cancer survival; the risk associated with the pathway merits validation in other studies.

    This retrospective cohort study examines mortality and cancer incidence among 3,686 men and 75 women who were employed as chemists in 1959. During the period 1964 to 1977, the male chemists experienced lower overall mortality than other salaried employees of the chemical company (198 deaths observed, 241.0 expected, SMR = 82). Large deficits are seen in lung cancer and arteriosclerotic heart disease death. The chemist appear to be at slightly higher risk for death from malignancies of the colon (12 observed, 6.7 expected, SMR = 178) and from cerebrovascular disease (15 observed, 10.8 expected, SMR = 138). The low overall mortality resulted in a larger than expected proportion of deaths due to cancer. Fewer than expected cases were diagnosed of cancer of all sited combined (61 observed, 86.5 expected, SIR = 71) and of the lung (8 observed, 20.0 expected, SIR = 40). The incidence rates of melanoma and of cancer of the prostate are slightly higher than expected, relative to the Third National Cancer Survey and the experience of nonchemists, respectively. Among female chemists, deaths due to all causes and suicide occurred more frequently than expected. Possible explanations for the lack of anticipated excess risks and for the observed deficits are presented. PMID:7252610

    2012-11-01

    Full Text Available Objective: This study examined global inequalities in cervical cancer incidence and mortality rates as a function of cross-national variations in the Human Development Index (HDI, socioeconomic factors, Gender Inequality Index (GII, and healthcare expenditure.Methods: Age-adjusted incidence and mortality rates were calculated for women in 184 countries using the 2008 GLOBOCAN database, and incidence and mortality trends were analyzed using the WHO cancer mortality database. Log-linear regression was used to model annual trends, while OLS and Poisson regression models were used to estimate the impact of socioeconomic and human development factors on incidence and mortality rates.Results: Cervical cancer incidence and mortality rates varied widely, with many African countries such as Guinea, Zambia, Comoros, Tanzania, and Malawi having at least 10-to-20-fold higher rates than several West Asian, Middle East, and European countries, including Iran, Saudi Arabia, Syria, Egypt, and Switzerland. HDI, GII, poverty rate, health expenditure per capita, urbanization, and literacy rate were all significantly related to cervical cancer incidence and mortality, with HDI and poverty rate each explaining >52% of the global variance in mortality. Both incidence and mortality rates increased in relation to lower human development and higher gender inequality levels. A 0.2 unit increase in HDI was associated with a 20% decrease in cervical cancer risk and a 33% decrease in cervical cancer mortality risk. The risk of a cervical cancer diagnosis increased by 24% and of cervical cancer death by 42% for a 0.2 unit increase in GII. Higher health expenditure levels were independently associated with decreased incidence and mortality risks.Conclusions and Public Health Implications: Global inequalities in cervical cancer are clearly linked to disparities in human development, social inequality, and living standards. Reductions in cervical cancer rates are achievable by

    Treatment-related mortality is an important outcome in paediatric cancer clinical trials. An international group of experts in supportive care in paediatric cancer developed a consensus-based definition of treatment-related mortality and a cause-of-death attribution system. The reliability and validity of the system was tested in 30 deaths, which were independently assessed by two clinical research associates and two paediatric oncologists. We defined treatment-related mortality as death occurring in the absence of progressive cancer. Of the 30 reviewed deaths, the reliability of classification for treatment-related mortality was noted as excellent by clinical research associates (κ=0·83, 95% CI 0·60-1·00) and paediatric oncologists (0·84, 0·63-1·00). Criterion validity was established because agreement between the consensus classifications by clinical research associates and paediatric oncologists was almost perfect (0·92, 0·78-1·00). Our approach should allow comparison of treatment-related mortality across trials and across time. PMID:26678213

  1. Competition, mortality, and development of spatial patterns in two Cantabrian populations of Fagus sylvatica L. (Fagaceae

    Fernández Prieto, José Antonio

    2000-06-01

    Full Text Available In this paper the spatial patterns of size and mortality of European beech (Fagus sylvatica L. were analy sed in two deciduous forest plots of Northern Spain. ¿i general terms, radial growth of F. sylvatica yields a direct relationship with size and an inverse relation with intraspecific competition while tree mortality seems be related to intraspecific competition. In the overall even-aged population, a lack of a recognisable structure in tree-size distribution, a small-scale regularity of survivors, and a regular pattern of dominant trees was noticed. This is a consequence of intense intraspecific competition at local level. In the old-growth plot, the wide repulsión between small and large beeches yields a specific spatial structure in tree-size distribution, showing even-sized groups of trees in different stages. Mortality in this plot occurs mainly within the dense group of small trees, which produces a broad regular pattern among the live beech trees. The random spatial pattern of dominant beeches seems to be characteristic of old-growth forests and could be a consequence of either self-thinning processes or exogenous factors.En el presente trabajo se analizan las distribuciones espaciales de tamaño y mortalidad en poblaciones de haya (Fagus sylvatica L. incluidas en dos parcelas de bosque atlántico. En general, el crecimiento radial de F. sylvatica es directamente proporcional al tamaño e inversamente proporcional a la competencia intraespecífica, mientras que la mortalidad parece estar condicionada por competencia con individuos de la misma especie. La población formada sobre todo por árboles coetáneos presenta características espaciales indicativas de una intensa competencia intraespecífica entre árboles vecinos, como lo son la ausencia de una distribución ordenada de tamaños, regularidad local de los árboles vivos y un patrón regular en los árboles dominantes.

    Information on epidemiology is essential to evaluate care for the growing group of oral cancer patients. We investigated trends in incidence, mortality and relative survival rates for oral cavity cancer (OCC) and its subsites in the Netherlands from 1991 to 2010, and relate these to changes in stage and treatment. Patient (age, sex), tumour (subsite, stage) and treatment characteristics of patients diagnosed with OCC (ICD-O-3: C02-C06) in 1991-2010 were extracted from the Netherlands Cancer Registry. Incidence, mortality and 5-year relative survival rates over time are presented, as well as trends in type of treatment. The incidence of OCC increased with +1.2% (95%CI: +0.9%;+1.6%) per year: more strongly in women, stage I and IV disease, and in cancers of the tongue and gum. The mortality rate slightly rose (+0.8%, 95%CI: +0.3%;+1.3% per year), but differed by subsite. The 5-year relative survival improved from 57% in 1991-1995 to 62% in 2006-2010. The 5-year relative survival was better for women compared with men (64% and 55%, respectively), decreased with increasing stage, was the best for tongue cancer (63%) and the worst for cancer of the gum (56%) and floor of mouth cancer (55%). The relative excess risk of dying was higher for non-surgery-based treatments. Surgery was the main treatment option and the proportion of "surgery only" rose in stage I and III disease. The incidence and, to a lesser extent, mortality of OCC are increasing and therefore, even with slightly improving survival rates, OCC is an increasingly important health problem. PMID:27038013

    Oral cancer makes up 1%-2% of all cancers that may arise in the body. The majority of oral cancers consists of squamous cell carcinomas. Oral cancer carries a considerable mortality rate, being mainly dependent on the stage of the disease at admission. Worldwide some 50% of the patients with oral cancer present with advanced disease. There are several ways of trying to diagnose oral cancer in a lower tumor stage, being 1) mass screening or screening in selected patients, 2) reduction of patients' delay, and 3) reduction of doctors' delay. Oral cancer population-based screening ("mass screening") programs do not meet the guidelines for a successful outcome. There may be some benefit when focusing on high-risk groups, such as heavy smokers and heavy drinkers. Reported reasons for patients' delay range from fear of a diagnosis of cancer, limited accessibility of primary health care, to unawareness of the possibility of malignant oral diseases. Apparently, information campaigns in news programs and TV have little effect on patients' delay. Mouth self-examination may have some value in reducing patients'delay. Doctors' delay includes dentists' delay and diagnostic delay caused by other medical and dental health care professionals. Doctors' delay may vary from almost zero days up to more than six months. Usually, morbidity of cancer treatment is measured by quality of life (QoL) questionnaires. In the past decades this topic has drawn a lot of attention worldwide. It is a challenge to decrease the morbidity that is associated with the various treatment modalities that are used in oral cancer without substantially compromising the survival rate. Smoking cessation contributes to reducing the risk of oral cancers, with a 50% reduction in risk within five years. Indeed, risk factor reduction seems to be the most effective tool in an attempt to decrease the morbidity and mortality of oral cancer. PMID:23229266

    Though larger social networks are associated with reduced breast cancer mortality, there is a need to clarify how both social support and social burden influence this association. We included 4,530 women from the Women's Health Initiative who were diagnosed with breast cancer between 1993 and 2009, and provided data on social networks (spouse or intimate partner, religious ties, club ties, and number of first-degree relatives) before diagnosis. Of those, 354 died during follow-up, with 190 from breast cancer. We used Cox proportional hazards regression to evaluate associations of social network members with risk of post-diagnosis mortality, further evaluating associations by social support and social burden (caregiving, social strain). In multivariate-adjusted analyses, among women with high but not low social support, being married was related to lower all-cause mortality. By contrast, among women with high but not low social burden, those with a higher number of first-degree relatives, including siblings, parents, and children, had higher all-cause and breast cancer mortality (among caregivers: 0–3 relatives (ref), 4–5 relatives, HR = 1.47 (95% CI: 0.62–3.52), 6–9 relatives, HR = 2.08 (95% CI: 0.89–4.86), 10+ relatives, HR = 3.55 (95% CI: 1.35–9.33), P-continuous = 0.02, P-interaction = 0.008). The association by social strain was similar though it was not modified by level of social support. Other social network members were unrelated to mortality. Social relationships may have both adverse and beneficial influences on breast cancer survival. Clarifying these depends on understanding the context of women's relationships. PMID:22331479

    Full Text Available Abstract Background International cohort studies have shown that antiretroviral treatment (ART has improved survival of HIV-infected individuals. National population based studies of HIV mortality exist in industrialized settings but few have been presented from developing countries. Our objective was to investigate on a population basis, the regional situation regarding HIV mortality and trends in Latin America (LA in the context of adoption of public ART policies and gender differences. Methods Cause of death data from vital statistics registries from 1996 to 2007 with "good" or "average" quality of mortality data were examined. Standardized mortality rates and Poisson regression models by country were developed and differences among countries assessed to identify patterns of HIV mortality over time occurring in Latin America. Results Standardized HIV mortality following the adoption of public ART policies was highest in Panama and El Salvador and lowest in Chile. During the study period, three overall patterns were identified in HIV mortality trends- following the adoption of the free ART public policies; a remarkable decrement, a remarkable increment and a slight increment. HIV mortality was consistently higher in males compared to females. Mean age of death attributable to HIV increased in the majority of countries over the study period. Conclusions Vital statistics registries provide valuable information on HIV mortality in LA. While the introduction of national policies for free ART provision has coincided with declines in population-level HIV mortality and increasing age of death in some countries, in others HIV mortality has increased. Barriers to effective ART implementation and uptake in the context of free ART public provision policies should be further investigated.

  17. Mortality and cancer incidence experience of employees in a nuclear fuels fabrication plant

    International Nuclear Information System (INIS)

    The mortality and cancer incidence experience of 4,106 employees in a nuclear fuels fabrication plant was evaluated in this retrospective cohort study. Standardized mortality (SMR) and incidence ratios were calculated for groups of employees holding different jobs in the company associated with various types of industrial exposures and with low levels of radiation. Connecticut population mortality rates and Connecticut Tumor Registry incidence rates, specific for age-sex, calendar year and cause of death or cancer site, were used for the calculation of expected rates. Results showed the SMR for all male employees to be significantly lower than expected for all causes and what would be expected for all cancer deaths. More deaths were observed than expected from diseases of the central and peripheral nervous system and from obstructive pulmonary disease. The overall cancer incidence experience of the male employees was significantly lower than expected; cancer of the brain was found to be significantly higher than expected among the industrial employees. There was no risk associated with any particular job exposure group. Log linear models analysis showed no significant effect from industrial and radiation exposures or from their combined influence

  18. The Estonian study of Chernobyl cleanup workers: II. Incidence of cancer and mortality

    International Nuclear Information System (INIS)

    A cohort of 4,472 men from Estonia who had participated in the cleanup activities in the Chernobyl area sometime between 1986 and 1991 and were followed through 1993 was analyzed with respect to the incidence of cancer and mortality. Incidence and mortality in the cleanup workers were assessed relative to national rates. No increases were found in all cancers (25 incident cases compared to 26.5 expected) or in leukemia (no cases observed, 1.0 expected). Incidence did not differ statistically significantly from expectation for any individual cancer site or type, though lung cancer and non-Hodgkin's lymphoma both occurred slightly more often than expected. A total of 144 deaths were observed [standardized mortality ratio (SMR) = 0.98; 95% confidence interval (CI) = 0.82-1.14] during an average of 6.5 years of follow-up. Twenty-eight deaths (19.4%) were suicides (SMR = 1.52; 95% CI = 1.01-2.19). Exposure to ionizing radiation while at Chernobyl has not caused a detectable increase in the incidence of cancer among cleanup workers from Estonia. At least for the short follow-up period, diseases directly attributable to radiation appear to be of relatively minor importance when compared with the substantial excess of deaths due to suicide. 28 refs., 3 tabs

  19. An overview of the cancer mortality data on the atomic bomb survivors

    International Nuclear Information System (INIS)

    A brief description is given of the cancer mortality data at the Radiation Effects Research Foundation, with the aim of providing some general perspective on the extent of the excess cancer mortality, for those who may not be inclined to glean this information from the more comprehensive reports on the Life Span Study. In addition, a summary is given of the changes in dosimetry given by the recently installed DS86 system. Even a cursory view of these changes requires consideration of several factors; changes in air doses, in environmental and organ shielding factors, in the extent of the neutron component, and in effects of truncation of exposures at 6 Gy. Finally, a brief discussion is given of the evolution of radiogenic cancer risk estimates during the past 10-15 years. (author)

    Objectives To evaluate trends in premature cancer mortality in Colombia by educational level in three periods: 1998–2002 with low healthcare insurance coverage, 2003–2007 with rapidly increasing coverage and finally 2008–2012 with almost universal coverage (2008–2012). Setting Colombian population-based, national secondary mortality data. Participants We included all (n=188 091) cancer deaths occurring in the age group 20–64 years between 1998 and 2012, excluding only cases with low levels of quality of registration (n=2902, 1.5%). Primary and secondary outcome measures In this descriptive study, we linked mortality data of ages 20–64 years to census data to obtain age-standardised cancer mortality rates by educational level. Using Poisson regression, we modelled premature mortality by educational level estimating rate ratios (RR), relative index of inequality (RII) and the Slope Index of Inequality (SII). Results Relative measures showed increased risks of dying among the lower educated compared to the highest educated; this tendency was stronger in women (RRprimary 1.49; RRsecondary 1.22, both p<0.0001) than in men (RRprimary 1.35; RRsecondary 1.11, both p<0.0001). In absolute terms (SII), cancer caused a difference per 100 000 deaths between the highest and lowest educated of 20.5 in males and 28.5 in females. RII was significantly higher among women and the younger age categories. RII decreased between the first and second periods; afterwards (2008–2012), it increased significantly back to their previous levels. Among women, no significant increases or declines in cancer mortality over time were observed in recent periods in the lowest educated group, whereas strong recent declines were observed in those with secondary education or higher. Conclusions Educational inequalities in cancer mortality in Colombia are increasing in absolute and relative terms, and are concentrated in young age categories. This trend was not curbed by increases in

    Among the country’s 25 largest cities, the breast cancer mortality disparity is highest in Memphis, Tennessee, where African American women are twice as likely to die from breast cancer as White women. This qualitative study of African-American breast cancer survivors explores experiences during and post treatment that contributed to their beating the high odds of mortality. Using a semi-structured interview guide, a focus group session was held in 2012 with 10 breast cancer survivors. Thematic analysis and a deductive a priori template of codes were used to analyze the data. Five main themes were identified: family history, breast/body awareness and preparedness to manage a breast cancer event, diagnosis experience and reaction to the diagnosis, family reactions, and impact on life. Prayer and family support were central to coping, and survivors voiced a cultural acceptance of racial disparities in health outcomes. They reported lack of provider sensitivity regarding pain, financial difficulties, negative responses from family/friends, and resiliency strategies for coping with physical and mental limitations. Our research suggested that a patient-centered approach of demystifying breast cancer (both in patient-provider communication and in community settings) would impact how women cope with breast cancer and respond to information about its diagnosis.

    Objective To investigate whether asbestosis is a risk factor for mortality of lung cancer. Methods A fixed cohort study was established in an asbestos plant in Chongqing, China, and followed up for 30 years from the beginning of 1972. Basic personal information on life state, cause of death, and diagnosis of asbestosis was collected. Multiple logistic regressions were applied to analyze risk factors. Results During the 30-year follow-up, 584 male workers constituting a total of 14 664 person-years were monitored and data were analyzed. Among them, 203 (34.8%) died and the mortality rate was 13.8 per 1000 person-years, cancer accounting for 37.4%. Excess risks were observed for lung cancer (OR=3.72) and nonmalignant respiratory diseases (OR=2.73) among workers with asbestosis. High-exposure level was another risk factor for lung cancer (OR=3.20). Workers with category Ⅱ of asbestusis demonsatrated a higher OR of both lung cancer and nonmalignant respiratory diseases than those with category Ⅰ of asbestosis. Conclusion High asbestos exposure level and asbestosis were the risk factors for death of lung cancer and nonmalignant respiratory diseases. Asbestosis is an independent risk factor for lung cancer among Chinese workers exposed to chrysotile, the risk increases with the increasing profusion of opacities of lung.

    The Florida manatee (Trichechus manatus latirostris) is an endangered marine mammal whose coastal habitat has been heavily altered by human development. Sources of mortality include anthropogenic and environmental causes. Necropsies were completed on 75 deceased individuals, and tissues, including bone samples, were collected for later analysis. This study investigates the utility of manatee bone stable oxygen (δ18O), sulfur (δ34S) and deuterium (δD) for determining where the animals lived (which may not be where they where their bodies were recovered), and the relative importance of marine versus freshwater for the individual animals. The isotopes can provide a "geochemical map" showing the distribution of mortality, aiding in the evaluation of geographical patterns in mortality. The δ18O signatures of the bones ranged from 14 to 18.5‰, with no significant difference between male and female mean values. δ18O significantly decreased with increasing latitude (p=.0016), a trend positively correlated with coastal Florida seawater δ18O literature values obtained from the NASA Global Seawater Oxygen-18 Database (http://data.giss.nasa.gov/o18data/) and the EAIA stable isotope database (http://www.univie.ac.at/cartography/project/wiser/). Bone δ34S indicated the influence of marine versus coastal freshwater dietary sources on the animals. Most individuals showed 34S-depleted signatures, which indicated a non-marine sulfur source; however some individuals clearly had taken up marine sulfate (mean 4.9 ± 3.7‰, range 0.8 to 13.8‰). Deuterium values were not available at the time this abstract was written, however we hypothesize that those values will co-vary with δ18O. We conclude that manatee diets are based on both marine and freshwater sources, but freshwater sources exert more influence. Marine water and manatee δ18O co-vary with latitude, suggesting that stable oxygen isotopes may be useful indicators of the latitude where manatees lived.

    Full Text Available Abstract Background Ethiopia is encountering a growing burden of non-communicable diseases along with infectious diseases, perinatal and nutritional problems that have long been considered major problems of public health importance. This retrospective analysis was carried out to examine the mortality patterns from communicable diseases and non communicable diseases in public and private hospitals of Addis Ababa. Methods Approximately 47,153 deaths were captured over eight years (2002–2010 in forty three public and private hospitals of Addis Ababa, Ethiopia. Data collectors (43 hospital clerks and coordinators (3 nurses had been extensively trained on how to review hospital death records. Information obtained included: dates of admission and death, age, sex, address, and principal cause of death. Only the diseases responsible for deaths are taken as the cause of death. Cause of death was coded using International Classification of Diseases (ICD-10 and data were double entered. Diseases were classified into: Group I (communicable diseases, maternal conditions and nutritional deficiencies; Group II (non-communicable causes; and Group III (injuries. Percentages, proportional mortality ratios, 95% confidence intervals (CI and Adjusted odd ratios (OR were calculated. Results Overall, 59% of the deaths were attributed to Group I diseases, and 31% to Group II diseases and 12% to injuries. Nearly 56% of the males and 68% of the females deaths were due to five leading causes (conditions arising during perinatal period, HIV/AIDS, tuberculosis, cardiovascular diseases and respiratory infections. Significantly larger proportions of females died from Group I (67% and Group II diseases (32% compared with males (where the respective proportions were 52% and 30%. Significantly higher proportion of males (17% than females (6% were dying from Group III diseases. Deaths due to Group I diseases decreased while those due to Group II diseases increased with age

  7. Analysis of the lung cancer mortality in Mayak worker cohort with a model of carcinogenesis

    International Nuclear Information System (INIS)

    Lung cancer mortality in the Mayak worker cohort is analysed with the two stage clonal expansion (TSCE) model of carcinogenesis. Reactor workers in Mayak facilities were exposed to external γ-ray and neutron exposures, and workers in the radiochemical and plutonium facilities additionally to internal exposures due to plutonium inhalation. The cohort used in this study involves male nuclear workers for whom plutonium measurements and smoking information (smoker/non-smoker) exists and with health follow-up to the end of 1999. A subcohort with 5421 workers and 274 lung cancer deaths is analysed. Specific emphasis was given to the distinction of the effects of external and internal exposures. Within the TSCE model, an action of radiation was assumed both in initiation and promotion. The baseline lung cancer mortality rate was derived from the cohort itself. The model which gives the best fit of the data has a linear dose dependence in TSCE-model parameters for both external and internal radiation. Using the smoking information significantly increased the quality of the fit. Analysis showed no effect of radiation on transformation. It is found that most of the lung cancer cases are due to plutonium inhalation. The estimated excess relative risk per unit dose due to the plutonium αparticles is 0.13/Sv. For the γ-ray component, the present analysis gives an excess relative risk for lung cancer mortality of 0.05/Sv. Lung cancer mortality among Mayak workers is analysed within two step clonal expansion model. Models of carcinogenesis are well suited for analysing data with complex exposure scenario. Resulting risk for plutonium exposures is compatible with the radiation weighting factor 20. In general no strong dose or dose-rate effects were observed within the cohort

    Cervical cancer causes significant morbidity and mortality worldwide. Most cervical cancers are associated with oncogenic human papillomavirus (HPV), and vaccination with any of 3 available HPV vaccines is anticipated to greatly reduce the burden of cervical cancer. This review provides an overview of the burden of HPV, the efficacy and clinical effectiveness of the bivalent (HPV 16, 18), quadrivalent (HPV 6, 11, 16, 18) and 9vHPV (HPV 6, 11, 16, 1831, 33, 45, 52, 58) vaccines in order to assess the anticipated impact on cervical cancer. All three vaccines show high efficacy in prevention of vaccine-specific HPV-type infection and associated high-grade cervical dysplasia in HPV-naïve women. Early clinical effectiveness data for the bivalent and quadrivalent vaccine demonstrate reduced rates of HPV 16 and 18 prevalence in vaccinated cohorts; data evaluating cervical dysplasia and cervical procedures as outcomes will shed further light on the clinical effectiveness of both vaccines. The bivalent vaccine has demonstrated cross-protection to non-vaccine HPV types, including the types in the 9vHPV vaccine. No clinical effectiveness data is yet available for the 9vHPV vaccine.  While HPV vaccination has great promise to reduce cervical cancer morbidity and mortality, estimated benefits are largely theoretical at present. Large population-based clinical effectiveness studies will provide long-term immunogenicity and effectiveness, as well as assessment of cervical cancer as an endpoint, particularly as young vaccinated women enter the appropriate age range to initiate screening for cervical cancer. Strengthening screening and treatment programs will likely have the greatest impact in the short-term on cervical cancer morbidity and mortality. PMID:26588179

    . Otolith radius and larval standard length were highly correlated, and otolith growth was used as a measure of larval somatic growth. The larvae were divided into 3 groups dependent on their hatch-date, and for each hatch group, the same period of past growth was compared between fish sampled in April and...... May. A 2-way repeated-measurement ANOVA revealed a significant higher past growth of fish sampled in May in 2 of the 3 hatch-groups, implying a higher mortality of the slow growing larvae. Additionally, otolith size at age differed significantly between the April and May sampling of the oldest larvae......We investigated growth patterns and evidence of growth dependent survival for a population of Atlantic cod Gadus morhua using analysis of their otolith microstructure. Central concentrations of a population of cod larvae and juveniles in the north-eastern North Sea were sampled twice (in April and...

    Cancer Registries are an essential part of any rational programme of cancer control, for assessing the impact of cancer in the community, for health care planning and monitoring screening programmes, according to local enviromental problems. The Brescia Cancer Registry started in 1994 producing prevalence, incidence and mortality data using only manual procedures of colletting and processing data from clinical and pathological sources in Brescia in 1993--1995. Data quality indicators such as the percentages of istologically or cytologically verified cases and that of cases registered on the basis of Death Certificate Only (DCO) are similar to those from the other Northern Italian Registries. Incidence rates for all causes and for various common sites are higher in Brescia than in other areas covered by Cancer Registries in North of Italy. PMID:15697007

    Lymphocyte apoptosis is thought to have a major role in the pathophysiology of sepsis. However, there is a disconnect between animal models of sepsis and patients with the disease, because the former use subjects that were healthy prior to the onset of infection while most patients have underlying comorbidities. The purpose of this study was to determine whether lymphocyte apoptosis prevention is effective in preventing mortality in septic mice with preexisting cancer. Mice with lymphocyte Bcl-2 overexpression (Bcl-2-Ig) and wild type (WT) mice were injected with a transplantable pancreatic adenocarcinoma cell line. Three weeks later, after development of palpable tumors, all animals received an intratracheal injection of Pseudomonas aeruginosa. Despite having decreased sepsis-induced T and B lymphocyte apoptosis, Bcl-2-Ig mice had markedly increased mortality compared with WT mice following P. aeruginosa pneumonia (85 versus 44% 7-d mortality; p = 0.004). The worsened survival in Bcl-2-Ig mice was associated with increases in Th1 cytokines TNF-α and IFN-γ in bronchoalveolar lavage fluid and decreased production of the Th2 cytokine IL-10 in stimulated splenocytes. There were no differences in tumor size or pulmonary pathology between Bcl-2-Ig and WT mice. To verify that the mortality difference was not specific to Bcl-2 overexpression, similar experiments were performed in Bim(-/-) mice. Septic Bim(-/-) mice with cancer also had increased mortality compared with septic WT mice with cancer. These data demonstrate that, despite overwhelming evidence that prevention of lymphocyte apoptosis is beneficial in septic hosts without comorbidities, the same strategy worsens survival in mice with cancer that are given pneumonia.

  14. Mathematical simulation for estimating reduction of breast cancer mortality in mass screening using mammography

    International Nuclear Information System (INIS)

    In Japan it is considered that mammography should be introduced with physical examination for the mass screening of breast cancer instead of physical examination alone, which is performed at present. Before the introduction of mammography, a mathematical simulation should be performed to show the reduction in breast cancer mortality by mass screening compared with an unscreened population. A mathematical model of cancer screening devised by the authors was used to estimate the number of deaths due to breast cancer (A) in the screened group and those (B) in the unscreened group within the same population. Then the relative risk (RR) and attributable risk (RD) were calculated as (A/B) and (B-A) respectively. Three methods of mass screening were compared: (1) physical examination (1-year interval), (2) mammography with physical examination (1-year interval), (3) mammography with physical examination (2-year interval). The calculated RR values were 0.85 for (1), 0.60 for (2) and 0.69 for (3). Assuming that the incidence of breast cancer was 100/105 person-years, the calculated RD values were 3.0, 8.1 and 6.2 persons/105 person-years for (1), (2) and (3), respectively. The 95% confidence interval of RR for three methods was over 1.0, and thus the reduction of breast cancer mortality was not statistically significant in the present population. In conclusion, mammography with physical examination may reduce breast cancer mortality in comparison with physical examination alone, but a larger number of women must be screened in order to obtain a significant RR value.

  15. The relative effect of mammographic screening on breast cancer mortality by socioeconomic status

    Abstract Breast cancer incidence and mortality are higher in women with a high socioeconomic status (SES). The potential to prevent death from breast cancer is therefore greater in the high SES group. This does, however, require that the effectiveness of screening in the high SES group is equal to or greater than the effectiveness in the low SES group. The aim of this study is to assess the relative effectiveness of mammographic screening on breast cancer mortality by SES. In Nijmegen, the Netherlands, women are invited to participate in biennial mammographic screening since 1975. Postal code is collected at each round and is used to calculate the SES of each woman based on the SES indicator of the Netherlands Institute for Social Research. The Dutch average was used to classify the SES score of each woman as either high or low. We designed a case-control study to investigate the effect of mammographic screening in women aged 50 to 75, 40 to 75, and 50 to 69 years, and calculated the odds ratios (ORs) and 95% confidence intervals (CIs). Among the women invited to the mammographic screening program in Nijmegen, 10% had a high SES. In women aged 50 to 75 years, the breast cancer death rate was 38% lower in screened women than in unscreened women. The ORs for women with high SES (OR 0.82, 95% CI 0.31–2.19) and low SES did not differ significantly (OR 0.61, 95% CI 0.47–0.78). Mammographic screening reduces breast cancer mortality, but we did not observe a significant difference in the relative effectiveness of screening by SES. If the effectiveness of mammographic screening is indeed not dependent on SES status, the absolute number of breast cancer deaths prevented by mammographic screening will be greater in the high SES than low SES group, because women with a high SES have a greater risk of breast cancer death.

    2006-07-01

    A cohort study of German nuclear power workers was set up to investigate overall and cancer mortality risk related to a chronic exposure to ionising radiation of low-level dose. The German study was performed as a part of an international study carried out by the International Agency for Research on Cancer (IARC), Lyon. First results of the international study have been published recently [1]. German data are not yet included in this analysis. The German cohort consists of 4844 employees from 10 nuclear power plants. All persons who worked in these nuclear power plants in 1991 or started employment between 1991 und 1997 are included (except for employees of one plant, whose observation period started in 1992). These persons accumulated about 31,000 person years. Overall, 68 deaths were observed in the observation period between 1.1.1991-31.12.1997. Standardized mortality ratios (SMR) were computed for all causes of death, all cancers, cardiovascular diseases, external causes, and all other causes. Overall, a strong healthy worker effect was observed (SMR=0.52 [95% CI: 0.41;0.67]). No increase in total cancer mortality was seen (SMR=0.85 [95% CI: 0.53;1.30]). However, numbers are too small for stable risk estimates and further effort is under way to complete the cohort in terms of power plants and to extend the follow-up until 2005. (authors)

    The exposure-response for hexavalent chromium (Cr(VI))-induced lung cancer among workers of the Painesville Ohio chromate production facility has been used internationally for quantitative risk assessment of environmental and occupational exposures to airborne Cr(VI). We updated the mortality of 714 Painesville workers (including 198 short-term workers) through December 2011, reconstructed exposures, and conducted exposure-response modeling using Poisson and Cox regressions to provide quantitative lung cancer risk estimates. The average length of follow-up was 34.4 years with 24,535 person-years at risk. Lung cancer was significantly increased for the cohort (standardized mortality ratio (SMR)=186; 95% confidence interval (CI) 145–228), for those hired before 1959, those with >30-year tenure, and those with cumulative exposure >1.41 mg/m3-years or highest monthly exposures >0.26 mg/m3. Of the models assessed, the linear Cox model with unlagged cumulative exposure provided the best fit and was preferred. Smoking and age at hire were also significant predictors of lung cancer mortality. Adjusting for these variables, the occupational unit risk was 0.00166 (95% CI 0.000713–0.00349), and the environmental unit risk was 0.00832 (95% CI 0.00359–0.0174), which are 20% and 15% lower, respectively, than values developed in a previous study of this cohort.

  18. Cancer mortality risk of nuclear power workers due to the exposure of ionising radiation in Germany

    International Nuclear Information System (INIS)

    A cohort study of German nuclear power workers was set up to investigate overall and cancer mortality risk related to a chronic exposure to ionising radiation of low-level dose. The German study was performed as a part of an international study carried out by the International Agency for Research on Cancer (IARC), Lyon. First results of the international study have been published recently [1]. German data are not yet included in this analysis. The German cohort consists of 4844 employees from 10 nuclear power plants. All persons who worked in these nuclear power plants in 1991 or started employment between 1991 und 1997 are included (except for employees of one plant, whose observation period started in 1992). These persons accumulated about 31,000 person years. Overall, 68 deaths were observed in the observation period between 1.1.1991-31.12.1997. Standardized mortality ratios (SMR) were computed for all causes of death, all cancers, cardiovascular diseases, external causes, and all other causes. Overall, a strong healthy worker effect was observed (SMR=0.52 [95% CI: 0.41;0.67]). No increase in total cancer mortality was seen (SMR=0.85 [95% CI: 0.53;1.30]). However, numbers are too small for stable risk estimates and further effort is under way to complete the cohort in terms of power plants and to extend the follow-up until 2005. (authors)

    There is limited information on the health effects of radon in drinking water in spite of their potential exposures. We conducted an ecological study in a small town in Japan where the groundwater with high concentrations of radon is supplied as utilities. A total of 607 cancer deaths were ascertained by vital statistics in that town from 1972 to 1997. Standardized mortality ratios on the basis of national rates were 1.01 (95% confidence interval; 0.93-1.09) for all cancers, 1.10 (0.95-1.28) for stomach cancer, 0.88 (0.70-1.10) for lung cancer, and 1.14 (0.87-1.48) for liver cancer. Mortality from liver cancer was significantly higher than that of two surrounding control cities combined, with a relative risk of 1.40 (1.04-1.89) based on Poisson regression analysis. Lack of information on possible confounders including diet, alcohol drinking, smoking and hepatitis virus infection, is the main limitation of the study, which precludes the evaluation of causal associations.

  1. Cancer mortality in women after repeated fluoroscopic examinations of the chest

    International Nuclear Information System (INIS)

    Among 1,047 women fluoroscopically examined in average of 102 times during pneumothorax therapy for tuberculosis and followed up to 45 years (average . 27 yr), no increase in the total number of cancer deaths occurred when these women were compared to 717 women who received other treatments [relative risk (RR) . 0.8]. However, elevated risks of mortality from stomach cancer (RR . 2.3), rectal cancer (RR . 3.8), breast cancer (RR . 1.2), lung cancer (RR . 1.8), and leukemia (RR . 1.2) were observed, but none was statistically significant and all were based on very small numbers of deaths. These increases were balanced by decreases of genital cancer (RR . 0.2), pancreatic cancer (RR . 0.9), lymphoma (RR . 0.6), and all other cancers (RR . 0.1). Average cumulative absorbed doses were 110 rads for the lungs, 33 rads for the trunk, 13 rads for the active bone marrow, and 7 rads for the stomach. The following upper levels of excess risk could be excluded with 95% confidence: 3.5 deaths/10(6) woman-year (WY)-rad for lung cancer, 4.8 deaths/10(6) WY-rad for lymphoma, and 12 deaths/10(6) WY-rad for leukemia. These findings indicated that the carcinogenic effect of multiple low-dose X-ray exposures was not greater than that currently assumed

    Full Text Available The metastatic disease which leads to cancer patients′ mortality results from a multi-step process of tumor progression caused by gene alteration and cooperation. Accordingly, it was recently demonstrated that alteration level of insulin-like growth factor-1 (IGF-1 and IGF binding protein-3 (IGFBP-3 are associated with the risk of cancer related death in several human malignancies including breast cancer. On the other hand, epithelial-mesenchymal transition (EMT is described as a crucial event in cancer progression and metastasis. Herein, we discuss the association between IGF-1, IGF-1/IGFBP-3 ratio, EMT, and breast cancer mortality.

    Full Text Available Abstract Background Different methods exist to estimate smoking attributable cancer mortality rates (Peto and Ezzati methods, as examples. However, the smoking attributable estimates using these methods cannot be generalized to all population sub-groups. A simpler method has recently been developed that can be adapted and applied to different population sub-groups. This study assessed cumulative tobacco smoke damage (smoke load/non-lung cancer mortality associations across time from 1979 to 2003 among all Massachusetts males and ages 30–74 years, using this novel methodology. Methods Annual lung cancer death rates were used as smoke load bio-indices, and age-adjusted lung/all other (non-lung cancer death rates were analyzed with linear regression approach. Non-lung cancer death rates include all cancer deaths excluding lung. Smoking-attributable-fractions (SAFs for the latest period (year 2003 were estimated as: 1-(estimated unexposed cancer death rate/observed rate. Results Male lung and non-lung cancer death rates have declined steadily since 1992. Lung and non-lung cancer death rates were tightly and steeply associated across years. The slopes of the associations analyzed were 1.69 (95% confidence interval (CI 1.35–2.04, r = 0.90, and 1.36 (CI 1.14–1.58, r = 0.94 without detected autocorrelation (Durbin-Watson statistic = 1.8. The lung/non-lung cancer death rate associations suggest that all-sites cancer death rate SAFs in year 2003 were 73% (Sensitivity Range [SR] 61–82% for all ages and 74% (SR 61–82% for ages 30–74 years. Conclusion The strong lung/non-lung cancer death rate associations suggest that tobacco smoke load may be responsible for most prematurely fatal cancers at both lung and non-lung sites. The present method estimates are greater than the earlier estimates. Therefore, tobacco control may reduce cancer death rates more than previously noted.

    Radiologically visible parenchymal changes (small opacities >= 1/0;ILO 1980 classification) were present in 20% of a sample of workers (N=174), employed for 20 years (median) in an asbestos cement plant. Exposure-response relationships were found, after controlling for age and smoking habits. In a sample of asbestos cement workers with symptoms and signs suggestive of pulmonary disease (N=33), increased lung density measured by x-ray computed tomography, and reduced static lung volumes and lung compliance was found. In a cohort of asbestos cement workers (N=1.929) with an estimated median exposure of 1.2 fibres/ml, the mortality from non-malignant respiratory disease was increased in comparison to a regional reference cohort (N=1.233). A two-to three-fold increase of non-malignant respiratory mortality was noted among workers employed for more than a decade in the asbestos cement plant, compared to cement workers (N=1.526), who in their turn did not experience and increased risk compared to the general population. In the cohorts of asbestos cement and cement workers, there was a tow-to three-fold increased incidence of cancer in the right part of the colon, compared to the general population as well as to external reference cohorts of other industrial workers (N=3.965) and fishermen (N=8.092). A causal relation with the exposure to mineral dust and fibres was supported by the findings of higher risk estimated in subgroups with high cumulated asbestos doses or longer duration of cement work. The incidence of cancer in the left part of the colon was not increased. Morbidity data, but not mortality data, disclosed the subsite-specific risk pattern. Both asbestos cement workers and cement workers has an increased incidence of rectal cancer, compared with the general population, and with the fishermen. The risk was, however, of the same magnitude among the other industrial workers. 181 refs.

    The aim of this study was to verify the relationship between weight loss, handgrip strength (HGS) and phase angle (PA) before the beginning of chemotherapy with overall survival in cancer patients. Patients diagnosed with gastrointestinal and breast cancer who were over 18 years old and were scheduled to undergo adjuvant treatment at Hospital Borges da Costa/Brazil were evaluated. The exclusion criteria were neoadjuvant treatment, patients with kidney and liver disease and using diuretics. Weight, HGS and PA tests were performed by trained dietitians. The Kaplan-Meier survival method and the log-rank test, cox regression and ROC curve were used and p loss of less than 10% of usual body weight (p loss and PA were predictors of mortality, HGS wasn't significantly associated with mortality. ROC analysis revealed that weight loss was the nutritional status parameter with the most predictive power. PMID:27348185

  6. Mortality from diseases other than cancer following low doses of ionizing radiation

    2007-01-01

    BACKGROUND: Ionizing radiation at very high (radio-therapeutic) dose levels can cause diseases other than cancer, particularly heart diseases. There is increasing evidence that doses of the order of a few sievert (Sv) may also increase the risk of non-cancer diseases. It is not known, however......, whether such effects also occur following the lower doses and dose rates of public health concern. METHODS: We used data from an international (15-country) nuclear workers cohort study to evaluate whether mortality from diseases other than cancer is related to low doses of external ionizing radiation....... Analyses included 275 312 workers with adequate information on socioeconomic status, over 4 million person-years of follow-up and an average cumulative radiation dose of 20.7 mSv; 11 255 workers had died of non-cancer diseases. RESULTS: The excess relative risk (ERR) per Sv was 0.24 [95% CI (confidence...

    The incidence of adult brain cancer was previously shown to be higher in countries where the parasite Toxoplasma gondii is common, suggesting that this brain protozoan could potentially increase the risk of tumor formation. Using countries as replicates has, however, several potential confounding factors, particularly because detection rates vary with country wealth. Using an independent dataset entirely within France, we further establish the significance of the association between T. gondii and brain cancer and find additional demographic resolution. In adult age classes 55 years and older, regional mortality rates due to brain cancer correlated positively with the local seroprevalence of T. gondii. This effect was particularly strong for men. While this novel evidence of a significant statistical association between T. gondii infection and brain cancer does not demonstrate causation, these results suggest that investigations at the scale of the individual are merited.

    Mammary tissue experiences the highest rate of proliferation during adolescence representing a period of heightened susceptibility. Few prospective studies have examined adolescent diet and breast cancer, and none have examined dietary patterns. Thus, we examined the association between adolescent dietary patterns and a diet quality index, the Alternative Healthy Eating Index (AHEI), and breast cancer in the Nurses' Health Study II among those who completed a 124-item food frequency questionnaire about their high-school diet (HS-FFQ). Cox proportional hazards regression models were used to calculate hazard ratios (HR) and 95% confidence intervals (95% CI). Among 45204 women who completed the HS-FFQ, 863 cases of premenopausal breast cancer and 614 cases of postmenopausal cancer were diagnosed. A marginal inverse association was observed between the 'prudent' dietary pattern, characterized by high intake of vegetables, fruits, legumes, fish and poultry, and premenopausal breast cancer. Women in fifth quintile had a multivariable adjusted HR (95% CI) of 0.84 (0.67-1.04) for premenopausal breast cancer (Ptrend= 0.07) compared with the first quintile. Scoring higher on the AHEI was borderline significantly associated with premenopausal breast cancer with a HR of 0.81 (0.64-1.01) for the fifth quintile (Ptrend= 0.08), and this association appeared to be stronger for estrogen receptor-negative/progesterone receptor-negative tumors. No association was observed between the 'Western' pattern or the 'fast-food' pattern. Results were similar for each of these patterns when both premenopausal and postmenopausal breast cancer were considered together. An overall healthy diet during adolescence, similar to the prudent dietary pattern or adherence to the AHEI, may contribute to reducing the risk of breast cancer. PMID:26905584

    Objective: To describe mortality pattern and to deter-mine undiagnosed fatal injuries according to autopsy find-ings among road traffic accident victims in Yazd, Iran. Methods: In this retrospective study, 251 victims of road traffic accidents who were admitted to a tertiary trauma hospital over a two-year period (2006 and 2007) and received medical cares were included. Hospital records were reviewed to gather demographic characteristics, road user type, and medical data. Autopsy records were also reviewed to determine actual causes of death and possible undiagnosed injuries occurred in the initial assessment of the emergency unit or during hospitalization. Results: There were 202 males (80.5%) and 49 females (19.5%). The mean (±SD) age of fatalities was 34.1 (±21.5) years. Pedestrian-vehicle accidents were the most common cause of trauma (100 cases, 39.8%). The most common cause of death was central nervous system injury ( 146 cases, 58.1%). The other causes were skull base fractures (10%), internal bleeding (8%), lower limb hemorrhage (8%), skull vault fractures (4%), cervical spinal cord injury (3.6%), airway com-promise (3.2%), and multifactor cases (5.1%), respectively.Thirtysix fatal injuries in 30 victims (12%) mainly contributed to death according to autopsy, but were not diagnosed in initial assessments. The head (72.2%) and cervical spine (13.8%) regions were the two most common sites for undiagnosed injuries. Conclusion: Training courses for emergency unit medical staff with regard to interpreting radiological findings of head and neck and high clinical suspicion for cervical spine injuries are essential to improve the quality of early hospital care and reduce the mortality and morbidity of traffic accident patients.

    Hrdlicka ([1914] Smithson. Inst. Misc. Collect. 61:1-69) reported that pre-Columbian skeletal material from the coastal lowland Andean region exhibited a high frequency of porotic hyperostosis, a pathological condition of bone that generally is thought to indicate childhood anemia. While subsequent studies tended to reinforce this conclusion, factors implicated in the condition have yet to be fully explored in the region as a whole. This study explores regional and intravalley variation as one step in establishing biocultural variables that increase the apparent risk of childhood anemia. The study sample includes 1,465 individuals: 512 from Peruvian collections housed at the Field Museum of Natural History, and 953 from systematically excavated contexts from Moquegua, Peru. Environmental stressors, such as parasites and disease, rather than specific dietary practices were found to be more likely associated with childhood anemia in these coastal Andean samples. The study supports cribra orbitalia as an earlier expression of porotic hyperostosis and suggests that porotic hyperostosis, as recorded here, cannot be easily dismissed as a result of cranial shape modification. No clear temporal patterns were observed. Finally, the study establishes that comparing data for children and adults can reveal the relative association between childhood anemia and mortality. Childhood mortality associated with anemia was elevated where the presence of tuberculosis or tuberculosis-like conditions was more common and the presence of water-borne pathogens was negligible. In contrast, those buried at lower altitudes, closer to the coast, and consuming mainly marine resources were less likely to die in childhood with anemia than in the other contexts studied.

  16. Statistical analyses of cancer mortality data of high background radiation areas of Yangjiang

    International Nuclear Information System (INIS)

    The author describes the methodology and results of the recent statistical analysis of cancer mortality data between 1970-1986 of high background radiation areas in Yangjiang, Guangdong, China. This analysis emphases on the establishment of reasonable mathematical models, parameter estimation techniques and combined analysis of data collected in different survey periods. Dose-response analyses were carried out in more detail to detect radiation effects. Statistical estimation of the upper confidence bounds of hazardous effect of radiation is given in terms of the upper confidence limit of excess relative risk of all cancers and of leukemia. The analysis further confirms that there is no correlation between radiation exposure and mortality from all cancers or from leukemia. Estimates of radiation induced cancer risk were made based on three mathematical models. Each model was designed for a specific subset of data which were collected differently in method or contain different information. The upper confidence limit of the excess relative risk was also estimated using the likelihood method. It is noted that the estimate of the upper bound of cancer risk is consistent with or similar to the result of occupational exposure and the risk extrapolated from the Japanese A-bomb study. Therefore, these results strengthen the conclusion that the estimates obtained through extrapolation from high dose data do not seriously underestimate the risk of low-dose exposure, but leave open the possibility that extrapolation may overestimate risks

  17. Morbidity and mortality pattern of hospitalized children with measles at mayo hospital, lahore (epidemic 2013)

    International Nuclear Information System (INIS)

    Major outbreak of measles took place in Punjab recently (2013), leading on to increase in hospitalized cases of measles in children wards, with unacceptably high morbidity and mortality. The aim of this study was to find out morbidity and mortality pattern of hospitalized cases of measles and associated factors. Design: Prospective case series conducted at Pediatric Department Mayo Hospital, Lahore for 7 months, i.e. from 1st Jan to 31st Jul 2013 Methods:A total of 628 cases of measles were admitted in the children ward, Unit II, Mayo Hospital, Lahore from Jan-Jul 2013. The diagnosis was assigned using WHO criteria. Cases were admitted through emergency on 24 hour basis and managed in HDU and Measles isolation section. Chest X-Ray and blood complete examination was done in all cases. Complications were noted and managed along with eye consultations where necessary. Data was recorded in a predesigned proforma and entered in computer. Results: 628 admitted cases were enrolled, with comparable sex distribution, having mean age 30.8+-26.25 months and mean weight 9.69+-4.14 Kg. Eighty three percent cases were below 6 years of age (33% <1 year), 71% cases were under weight and 68% were wasted (WHO classification). Sixty six percent cases had not received measles vaccination, 144 (23%) cases had received a single dose and 71 cases (12.2%) had received two doses before admission. Majority of cases belonged to Lahore city and its peri-urban areas (83%). Pneumonia (80%), diarrhea (37%), and encephalitis (7.7%) were common complications. Eye complications (corneal ulcers, keratitis, perforation and blindness) were seen in 7.3% cases. Being under weight, H/O improper measles immunization, presence of anemia, pneumonia and encephalitis were statistically significant risk factors for mortality. The case fatality rate was 8.76%. Conclusion:Recent Measles outbreak further highlights the importance of strengthening the need for routine and mass vaccination for all children. In a

  7. Lung cancer mortality among nonsmoking uranium miners exposed to radon daughters

    International Nuclear Information System (INIS)

    This paper reports on radon daughters, both in the workplace and in the household, that are a continuing cause of concern because of the well-documented association between exposure to radon daughters and lung cancer. To estimate the risk of lung cancer mortality among nonsmokers exposed to varying levels of radon daughters, 516 white men who never smoked cigarettes, pipes, or cigars were selected from the U.S. Public Health Service cohort of Colorado Plateau uranium miners and followed up from 1950 through 1984. Age-specific mortality rates for nonsmokers from a study of U.S. veterans were used for comparison. Fourteen deaths from lung cancer were observed among the nonsmoking miners, while 1.1 deaths were expected, yielding a standardized mortality radio of 12.7 with 95% confidence limits of 8.0 and 20.1. These results confirm that exposure to radon daughters in the absence of cigarette smoking is a potent carcinogen that should be strictly controlled

    Background. To evaluate whether insulin use was predictive for mortality from breast cancer in Taiwanese women with diabetes mellitus. Methods. A total of 48,880 diabetic women were followed up to determine the mortality from breast cancer during 1995–2006. Cox models were used, considering the following independent variables: age, sex, diabetes type, diabetes duration, body mass index, smoking, insulin use, and area of residence. Insulin use was also considered for its duration of use at cutoffs of 3 years and 5 years. Results. Age was a significant predictor in all analyses. The multivariable-adjusted hazard ratio (95% confidence interval, P value) for insulin use without considering the duration of use was not statistically significant (1.339 [0.782–2.293, P = 0.2878]). Compared with nonusers, insulin users showed the following adjusted hazard ratios for insulin use <3 years, ≥3 years, <5 years, and ≥5 years: 0.567 (0.179–1.791, P = 0.3333), 2.006 (1.102–3.653, P = 0.0228), 1.045 (0.505–2.162, P = 0.9048), and 1.899 (0.934–3.860, P = 0.0763). Conclusions. Insulin use (mainly human insulin) for ≥3 years may be associated with a higher risk of breast cancer mortality. PMID:26171401

    Abstract The purpose of this study was to determine the risk of surgical mortality and morbidity in patients with diabetes mellitus (DM) undergoing a gastrectomy for gastric cancer (GC). Using the Taiwan National Health Insurance Research Database, we identified 6284 patients who underwent gastrectomy for GC from 1999 to 2010. In addition, we created a non-DM control cohort consisting of 6268 patients who received gastrectomy during the same period. Compared with the non-DM cohort, the DM cohort exhibited a higher prevalence of preoperative coexisting medical conditions, namely hypertension, hyperlipidemia, coronary artery disease, chronic kidney disease, chronic pulmonary disease, stroke, and cirrhosis. The odds ratio (OR) of 30-day postoperative mortality after gastrectomy in the DM cohort was 1.04 (95% confidence interval 0.78–1.40) after we adjusted for covariates. The DM cohort did not exhibit a significantly higher risk of 30-day postoperative morbidities. Further analysis revealed that only patients with a history of a DM-related coma exhibited a higher risk of 30-day postoperative mortality (adjusted OR 2.46, 95% confidence interval 1.10 − 5.54). Moreover, the risk of 90-day postoperative mortality was significantly higher in patients with DM-related eye involvement, coma, peripheral circulatory disease, and renal manifestations, in comparison with the non-DM cohort. The risk of 90-day mortality after gastrectomy for GC is higher in patients with DM-related manifestations than those without DM. PMID:26376386

    in Monte Alegre and at the control counties remained stable, but the high proportion of unascertained causes of death at the mortality database does not allow a conclusive ascertainment. SMR for all causes of death in Monte Alegre was similar to that observed at the control counties, respectively, SMR=72.9, 95% CI 70,5-75,3 and SMR=75.2 , 95% CI 76,2-77,3. No excess of cancer deaths was observed in Monte Alegre or at the control populations, and cancer mortality by gender also did not reveal statistically significant differences at the different tumor sites. Despite the use of three different approaches to estimate cancer incidence in Monte Alegre and the control counties, similar patterns were observed in the studied areas. To conclude, no evidence supporting an increase of cancer deaths in Monte Alegre was observed. (author)

  12. The effect of performing corrections on reported uterine cancer mortality data in the city of São Paulo

    Full Text Available Reports of uterine cancer deaths that do not specify the subsite of the tumor threaten the quality of the epidemiologic appraisal of corpus and cervix uteri cancer mortality. The present study assessed the impact of correcting the estimated corpus and cervix uteri cancer mortality in the city of São Paulo, Brazil. The epidemiologic assessment of death rates comprised the estimation of magnitudes, trends (1980-2003, and area-level distribution based on three strategies: i using uncorrected death certificate information; ii correcting estimates of corpus and cervix uteri mortality by fully reallocating unspecified deaths to either one of these categories, and iii partially correcting specified estimates by maintaining as unspecified a fraction of deaths certified as due to cancer of "uterus not otherwise specified". The proportion of uterine cancer deaths without subsite specification decreased from 42.9% in 1984 to 20.8% in 2003. Partial and full corrections resulted in considerable increases of cervix (31.3 and 48.8%, respectively and corpus uteri (34.4 and 55.2% cancer mortality. Partial correction did not change trends for subsite-specific uterine cancer mortality, whereas full correction did, thus representing an early indication of decrease for cervical neoplasms and stability for tumors of the corpus uteri in this population. Ecologic correlations between mortality and socioeconomic indices were unchanged for both strategies of correcting estimates. Reallocating unspecified uterine cancer mortality in contexts with a high proportion of these deaths has a considerable impact on the epidemiologic profile of mortality and provides more reliable estimates of cervix and corpus uteri cancer death rates and trends.

    A number of epidemiologic studies have attempted to link the use of β blockers to mortality in cancer patients, but their findings have been inconclusive. A meta-analysis was carried out to derive a more precise estimation. Relevant studies were identified by searching PubMed and EMBASE to May 2015. We calculated the summary hazard ratios (HRs) and 95% confidence intervals (CIs) using random-effects models. Twenty cohort studies and four case-control studies involving 76 538 participants were included. The overall results showed that patients who used β blockers after diagnosis had an HR of 0.89 (95% CI 0.81-0.98) for all-cause mortality compared with nonusers. Those who used β blockers after diagnosis (vs. nonusers) had an HR of 0.89 (95% CI 0.79-0.99) for cancer-specific mortality. Prediagnostic use of β blockers showed no beneficial effect on all-cause mortality or cancer-specific mortality. Stratifying by cancer type, only breast cancer patients who used β blockers after diagnosis had a prolonged overall survival. A linear but nonsignificant trend was found between postdiagnostic β-blocker use and mortality of cancer patients. In conclusion, the average effect of β-blocker use after diagnosis but not before diagnosis is beneficial for the survival of cancer patients. PMID:26340056

  14. The effects of terrain shielding on cancer mortality in Nagasaki atomic bomb survivors

    International Nuclear Information System (INIS)

    Hills in environs around the hypocenter in Nagasaki City are suggested to have shielded (S) the resident in the hill back from A-bomb radiation (terrain shielding). The effect of this S on cancer mortality risk was analyzed by comparison with the risk in residents in non-shielded (NS) areas. An S area was selected at 2-3 km afar from the hypocenter and NS areas, at 2-3, 3-4 and 4-5 km (NS I, II, III, respectively). The subject cohorts were 1,579 residents in the S area, 1,504, 5,062 and 5,540 in the NS I, II and III areas, respectively; and were analyzed for their cancer death during 40 years from Jan. 1970 to Dec. 2009 by Cox proportional hazard model with covariates of the area, sex, age at exposure and death age. Cancer death was seen in 8.7% of the resident in S; and 11.9, 8.6 and 7.7% in NS I, NS II, and NS III, respectively. The hazard ratios of cancer mortality were 0.78 between areas S/NS I, 0.74 between N II/N I and 0.77 between N III/N I, which were all statistically significant. Thus reducing effect of S on cancer mortality was 22% as compared with that of residents in NS I, suggesting that the terrain shielding effect should be taken in consideration for evaluation of health hazard in Nagasaki.

    Full Text Available The association between malignancy and venous thromboembolic disease (VTE is well established. The independent impact of VTE, both symptomatic and incidental, on survival in patients with prostate cancer is not known. We conducted a retrospective cohort study to evaluate the effect of VTE of survival in prostate cancer.Data regarding clinical characteristics, treatment and outcomes of 453 consecutive prostate cancer patients were collected. Fisher exact (categorical variables and t-test (continuous variables were utilized to test associations with VTE and mortality. Survival was estimated using the Kaplan Meier method. A Cox regression model was used to model the mortality hazard ratio (HR.At diagnosis, 358 (83% patients had early stage disease, 43 (10% had locally advanced disease and 32 (7% had metastatic disease. During the follow up period, 122 (27% patients died and 41 (9% developed VTE (33 deep vein thrombosis, 5 pulmonary embolism, and 3 patients with both DVT and PE. Twenty-five VTE events were symptomatic and 16 were incidentally diagnosed on CT scans obtained for other reasons. VTE was associated with increased mortality [HR 6.89 (4.29-11.08, p<0.001] in a multivariable analysis adjusted for cancer stage, performance status, treatments and co-morbidities. There was no difference in survival between patients who had symptomatic and incidental VTE.Venous thromboembolic disease, both symptomatic and incidental, is a predictor of poor survival in patients with prostate cancer, especially those with advanced disease. Further studies are needed to evaluate the benefit of prophylactic and therapeutic anticoagulation in this population.

  16. Analysis of the lung cancer mortality in Mayak worker cohort with a model of carcinogenesis

    International Nuclear Information System (INIS)

    Lung cancer mortality in the Mayak worker cohort is analysed with the two stage clonal expansion (TSCE) model of carcinogenesis. Mayak production association includes a nuclear reactor, radiochemical plant and plutonium production plant. Reactor workers were exposed to external g-ray and neutron exposures, and workers in the radiochemical and plutonium facilities additionally to internal exposures due to plutonium inhalant ion. the cohort used in this study involves male nuclear workers for whom plutonium measurements and smoking information (smoker/non-smoker) exists and with health follow-up to the end of 1999. A Subcohort with 5421 workers and 274 lung cancer deaths is analysed. Within the TSCE model, an action of radiation was assumed both in initiation and promotion. specific emphasis was given to the distinction of the effects of external and internal exposures. The baseline lung cancer mortality rate was derived from the cohort itself. Using the smoking information significantly increased the quality of the fit. Analysis showed no effect of radiation on transformation. Two models are found to five equally good fit of the data. Both models have a linear dose dependence in TSCE-model parameters for external and internal radiation. Both models have linear dependence either initiation or promotion on birth year effect. It is found that most of the lung cancer cases are due to plutonium inhalation. The estimated excess relative risk per unit dose due to the plutonium a particles is 0.13/Sv, in both models. For the g-ray component, the present analysis gives an excess relative risk for lung cancer mortality of 0.02/Sv, in both models. Resulting risk for plutonium exposures is compatible with the radiation weighting factor 20. In general no strong dose or dose-rate effects were observed within the cohort. (Author)

    Background: Air pollution from road traffic has been associated to an increased risk of lung cancer. Herein, we investigated the association between lung cancer mortality and residence near Italian highways or national major roads. Methods: Information on deaths for lung cancer registered from 1990 to 2010 and stratified by age, gender, and urban or rural municipality of residence at death were obtained from the National Institute of Statistics. Distance between the centroid of the municipality of residence and closest major roadways was considered as a proxy of pollution exposure. Relative Risks (RR) and 95% confidence intervals (CI) were computed using Poisson log-linear models adjusted for age, calendar period, deprivation index, North/South gradient, and urban/rural status. Results: A gradient in risk for lung cancer mortality was seen for residents within 50 meters (m) of national major roads. In particular, in rural municipalities a statistically significant increased risk for lung cancer death was observed in both sexes (RR = 1.27 for distance <25 m vs. 500–1999 m, 95% CI 1.17–1.42, in men; RR = 1.97, 95% CI 1.64–2.39, in women). In urban municipalities, weak risks of borderline significance were documented in both sexes (RR = 1.06, 95% CI 0.99–1.15 in men; and RR = 1.09, 95% CI 0.97–1.22 in women). No statistically significant association emerged between residence within 100 to 500 m from highways and RRs of death for lung cancer. Conclusions: In Italy, residing near national major roads, in particular in rural municipalities, was related to elevated risks of death for lung cancer. PMID:26848674

    2012-04-01

    Full Text Available Abstract Background The study conducts statistical and spatial analyses to investigate amounts and types of permitted surface water pollution discharges in relation to population mortality rates for cancer and non-cancer causes nationwide and by urban-rural setting. Data from the Environmental Protection Agency's (EPA Discharge Monitoring Report (DMR were used to measure the location, type, and quantity of a selected set of 38 discharge chemicals for 10,395 facilities across the contiguous US. Exposures were refined by weighting amounts of chemical discharges by their estimated toxicity to human health, and by estimating the discharges that occur not only in a local county, but area-weighted discharges occurring upstream in the same watershed. Centers for Disease Control and Prevention (CDC mortality files were used to measure age-adjusted population mortality rates for cancer, kidney disease, and total non-cancer causes. Analysis included multiple linear regressions to adjust for population health risk covariates. Spatial analyses were conducted by applying geographically weighted regression to examine the geographic relationships between releases and mortality. Results Greater non-carcinogenic chemical discharge quantities were associated with significantly higher non-cancer mortality rates, regardless of toxicity weighting or upstream discharge weighting. Cancer mortality was higher in association with carcinogenic discharges only after applying toxicity weights. Kidney disease mortality was related to higher non-carcinogenic discharges only when both applying toxicity weights and including upstream discharges. Effects for kidney mortality and total non-cancer mortality were stronger in rural areas than urban areas. Spatial results show correlations between non-carcinogenic discharges and cancer mortality for much of the contiguous United States, suggesting that chemicals not currently recognized as carcinogens may contribute to cancer

  4. Dose-response relationship analysis for cancer and circulatory system disease mortality risks among uranium miners

    International Nuclear Information System (INIS)

    The relation between lung cancer risk and radon exposure has been clearly established, especially from the studies on uranium miner cohorts. But the association between radon exposure and extrapulmonary cancers and non-cancer diseases remains not well known. Moreover, the health risks associated with the other mining-related ionizing radiation exposures are still under consideration. The aim of this thesis is to contribute to the estimation of the radio-induced health risks at low-doses through the analysis of the kidney cancer and Circulatory System Disease (CSD) mortality risks among uranium miners. Kidney cancer mortality risk analyses were performed from the French cohort of uranium miners (n=5086; follow-up period: 1946-2007), the post-55 cohort (n=3,377; follow-up period: 1957-2007) and the German cohort of the Wismut (n=58,986; follow-up period: 1946-2003) which included 24, 11 and 174 deaths from kidney cancer, respectively. The exposures to radon and its short-lived progeny (expressed in Working Level Month WLM), to uranium ore dust (kBqh.m-3) and to external gamma rays (mSv) were estimated for each miners and the equivalent kidney dose was calculated. The dose-response relation was refined considering two responses: the instantaneous risk of kidney cancer mortality (corresponding to the classical analysis, Cause specific Hazard Ratio (CSHR) estimated with the Cox model) and its occurrence probability during the followup (Sub-distribution Hazard Ratio (SHR) estimated with the Fine and Gray model). An excess of kidney cancer mortality was observed only in the French cohort (SMR = 1.62 CI95%[1.04; 2.41]). In the Wismut cohort, a decrease of the kidney cancer mortality was observed (0.89 [0.78; 0.99]). For these three cohorts, the occupational radiological exposures (or the equivalent kidney dose) were significantly associated neither with the risk of kidney cancer mortality (e.g. CSHRWismut-radon/100 WLM=1.023 [0.993; 1.053]), nor with its occurrence

    Background: Considerable effort has been expended on tobacco control strategies in the United States since the mid-1950s. However, we have little quantitative information on how changes in smoking behaviors have impacted lung cancer mortality. We quantified the cumulative impact of changes in smoking behaviors that started in the mid-1950s on lung cancer mortality in the United States over the period 1975–2000. Methods: A consortium of six groups of investigators used common inputs consisting...

    Full Text Available Introduction: gastric cancer (GC is the fourth leading cause of cancer death in Spain after lung, colorectal, breast and prostate tumours. Surgery remains the only potentially curative treatment in localized gastric cancer. Objective: the aim of our study is to evaluate and compare the clinical and surgical aspects, development of postoperative complications and outcomes of patients over 75 years old compared with younger patients in our centre. Material and methods: comparative retrospective study, from March 2003 to June 2011. We diagnosed 166 cases of GC, 109 (65 % underwent curative surgery. Two groups were settled: group M: ≥ 75 years (41 patients and group m: < 75 years (68 patients. We analyzed age, sex, comorbidities, tumour location, clinical stage, perioperative chemotherapy, surgical technique, postoperative complications, recurrence and mortality from cancer. Results: a more frequent presence of cardiovascular comorbidities and a greater postoperative mortality by medical causes were the only significant differences between both groups. Also, a lower proportion of patients in group M received preoperative chemotherapy and underwent D1 lymphadenectomy. However, the rate of local and systemic recurrence and overall survival were similar in both groups. Conclusions: age should not be considered a contraindication for curative surgery on GC. The general condition and comorbidities are more important to contraindicate surgical treatment.

    Full Text Available AIMS: To test the hypothesis that cumulative exposure to insulin and long-acting insulin analogs might be associated with cancer mortality in diabetes patients. METHODS: All consecutive diabetes patients aged over 40 years, residing in a major urban area were screened at their first diabetes outpatient visit between 01/01/2001-12/31/2008 (n = 79869. Exclusion criteria were insulin treatment at screening, no insulin treatment until 12/31/2008, less than 6 months of glucose-lowering treatment alone before insulin initiation, insulin prescription before glargine became available, age <40/≥ 80 years at first insulin prescription, and <6 months of insulin exposure. A total 4990 subjects were followed-up for death based on death certificate, until 12/31/2011. Adjusted time-dependent competing risk regression analysis, with daily updates of treatment modalities was performed. Results are expressed for every 10,000 IU of cumulative dose or one year of cumulative time exposure to insulin. RESULTS: Mean baseline age was 62 ± 9 years, and follow-up 4.7 ± 1.9 years. Glargine cumulative dose was associated with lower cancer mortality risk (subhazard ratio, SHR: 0.94 (95%CI 0.89-0.99, p = 0.033. Cumulative exposure limited to that attained one year prior to death revealed lower SHRs for cumulative time (0.94 (95%CI 0.89-0.99, p = 0.018 and cumulative dose of glargine (0.92 (95%CI 0.86-0.98, p = 0.014. Glargine cumulative time and cumulative dose were significant predictors for lower pancreatic and breast cancer mortality, but not for deaths from lung, colorectal, female genital, liver, and urinary tract cancer. No increased hazards were found for any other subtypes of insulins. CONCLUSIONS: The cumulative dose exposure to insulin glargine was associated with a lower risk of cancer mortality in general, and of breast and pancreatic cancer in particular. This effect remained even after additional "fixed" cohort or propensity score analyses.

    Purpose: To investigate the utility of the interval to biochemical failure (IBF) after salvage radiation therapy (SRT) after radical prostatectomy (RP) for prostate cancer as a surrogate endpoint for distant metastasis (DM), prostate cancer-specific mortality (PCSM), and overall mortality (OM). Methods and Materials: A retrospective analysis of 575 patients treated with SRT after RP from a single institution. Of those, 250 patients experienced biochemical failure (BF), with the IBF defined as the time from commencement of SRT to BF. The IBF was evaluated by Kaplan-Meier and Cox proportional hazards models for its association with DM, PCSM, and OM. Results: The median follow-up time was 85 (interquartile range [IQR] 49.8-121.1) months, with a median IBF of 16.8 (IQR, 8.5-37.1) months. With a cutoff time of 18 months, as previously used, 129 (52%) of patients had IBF ≤18 months. There were no differences among any clinical or pathologic features between those with IBF ≤ and those with IBF >18 months. On log–rank analysis, IBF ≤18 months was prognostic for increased DM (P<.0001, HR 4.9, 95% CI 3.2-7.4), PCSM (P<.0001, HR 4.1, 95% CI 2.4-7.1), and OM (P<.0001, HR 2.7, 95% CI 1.7-4.1). Cox proportional hazards models with adjustment for other clinical variables demonstrated that IBF was independently prognostic for DM (P<.001, HR 4.9), PCSM (P<.0001, HR 4.0), and OM (P<.0001, HR 2.7). IBF showed minimal change in performance regardless of androgen deprivation therapy (ADT) use. Conclusion: After SRT, a short IBF can be used for early identification of patients who are most likely to experience progression to DM, PCSM, and OM. IBF ≤18 months may be useful in clinical practice or as an endpoint for clinical trials.

    Full Text Available Background: Many studies have established a link between weather (primarily temperature and daily mortality in developed countries. However, little is known about this relationship in urban populations in sub-Saharan Africa. Objectives: The objective of this study was to describe the relationship between daily weather and mortality in Nairobi, Kenya, and to evaluate this relationship with regard to cause of death, age, and sex. Methods: We utilized mortality data from the Nairobi Urban Health and Demographic Surveillance System and applied time-series models to study the relationship between daily weather and mortality for a population of approximately 60,000 during the period 2003–2008. We used a distributed lag approach to model the delayed effect of weather on mortality, stratified by cause of death, age, and sex. Results: Increasing temperatures (above 75th percentile were significantly associated with mortality in children and non-communicable disease (NCD deaths. We found all-cause mortality of shorter lag of same day and previous day to increase by 3.0% for a 1 degree decrease from the 25th percentile of 18°C (not statistically significant. Mortality among people aged 50+ and children aged below 5 years appeared most susceptible to cold compared to other age groups. Rainfall, in the lag period of 0–29 days, increased all-cause mortality in general, but was found strongest related to mortality among females. Low temperatures were associated with deaths due to acute infections, whereas rainfall was associated with all-cause pneumonia and NCD deaths. Conclusions: Increases in mortality were associated with both hot and cold weather as well as rainfall in Nairobi, but the relationship differed with regard to age, sex, and cause of death. Our findings indicate that weather-related mortality is a public health concern for the population in the informal settlements of Nairobi, Kenya, especially if current trends in climate change continue.

    Full Text Available  SUMMARYThe etiology of prostate cancer is to a large extent unknown. There are striking international variations inincidence, which may indicate that factors that show geographical variations can provide further cluesabout etiology. A problem with using incidence data for comparisons in time and space is that the numberof cases reported may be affected by the intensity of diagnosing, since many of the cases are latent andasymptomatic. The purpose of this study is to adjust the observed pattern of prostate cancer in communesand counties of Norway for variations which may be due to diagnostic artefacts. It is assumed that a largeproportion of local cancers may be an indication of more intensive diagnosing. Data of prostate cancerincidence for 1982-91 with tumours specified by degree of spread were provided by the Cancer Registry. Aregression function relating total incidence to % local tumours was used to predict the SIRs adjusted forvariations in % local tumours. The maps comparing incidence patterns before and after adjustement showthat a large part of the significant deviations from the national mean persists, and that the pattern of negativedeviations in the far north is even strengthened. A significant positive correlation between the ratio ofincidence to mortality against % local tumours is found, which supports the main hypothesis of the study.

    Full Text Available Objetive: The Population-based Cancer Registry of Cali aims to report all new cases in permanent residents within the limits of the city of Cali. Time trends of cancer incidence and mortality are described. The registry has been in continuous operation for 50 years. Methods: Cancer cases reports are obtained actively by visiting all sources of information: hospitals, pathology departments, hematology laboratories, radiotherapy centers, government offices where death certificates are processed and physician’s offices. It is estimated that the reporting is at least 95% complete. Results: Drastic decreases are documented in rates for tumors causally related to infectious agents, especially cancers of the uterine cervix and the stomach. Gradual increases are documented in rates of tumors linked to affluence and the metabolic syndrome, especially cancers of the colon and the female breast. An unexpected increase in the incidence of papillary carcinoma of the thyroid gland in women is reported. Tobacco-related cancers, especially cancer of the lung, showed marked increase in incidence rates around 1970, apparently the beginning of an epidemic similar to the one reported in Western societies. But the increase in incidence stopped around 1980, resulting from a strong anti-smoking campaign launched in Colombia in the 1970s. Conclusions: The findings have influenced prevention strategies implemented by public health authorities, specially the establishment of a city-wide program to prevent cervix cancer via widespread use of vaginal cytology and anti-smoking campaigns. Also, new population-based cancer registries have been established in other Colombian cities as well as in Ecuador.

  2. The relative contributions of different organ sites to the total cancer mortality associated with low-dose radiation exposure

    International Nuclear Information System (INIS)

    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.

    Recent ecological and case-control studies have indicated elevated lung cancer mortality (LCM) associated with bituminous "smoky" coal use in China, but no similar study has been conducted using U.S. populations. Early 20th century U.S. home cooking and heating fuels were examined in relation to age-specific female LCM, focusing on county-level mortality during 1950-54 to reduce potential inter-county confounding due to cigarette smoking among women aged 40* vs. 60* years (among whom 11% vs. 5% ever smoked, respectively). Overall, a significant relationship was found between female LCM and county-level average per capita bituminous coal use with and without adjustment for numerous covariates in counties where ~75% of homes used coal for heating. This positive association was similar in each female age group after adjustment of 190 combinations of variates considered in addition t

    Full Text Available Abstract Background An inverse relationship between solar ultraviolet-B (UV-B exposure and non-skin cancer mortality has long been reported. Vitamin D, acquired primarily through exposure to the sun via the skin, is believed to inhibit tumor development and growth and reduce mortality for certain cancers. Methods We extend the analysis of this relationship to include cancer incidence as well as mortality, using higher quality and higher resolution data sets than have typically been available. Over three million incident cancer cases between 1998 and 2002 and three million cancer deaths between 1993 and 2002 in the continental United States were regressed against daily satellite-measured solar UV-B levels, adjusting for numerous confounders. Relative risks of reduced solar UV-B exposure were calculated for thirty-two different cancer sites. Results For non-Hispanic whites, an inverse relationship between solar UV-B exposure and cancer incidence and mortality was observed for ten sites: bladder, colon, Hodgkin lymphoma, myeloma, other biliary, prostate, rectum, stomach, uterus, and vulva. Weaker evidence of an inverse relationship was observed for six sites: breast, kidney, leukemia, non-Hodgkin lymphoma, pancreas, and small intestine. For three sites, inverse relationships were seen that varied markedly by sex: esophagus (stronger in males than females, gallbladder (stronger in females than males, and thyroid (only seen in females. No association was found for bone and joint, brain, larynx, liver, nasal cavity, ovary, soft tissue, male thyroid, and miscellaneous cancers. A positive association between solar UV-B exposure and cancer mortality and incidence was found for anus, cervix, oral cavity, melanoma, and other non-epithelial skin cancer. Conclusion This paper adds to the mounting evidence for the influential role of solar UV-B exposure on cancer, particularly for some of the less-well studied digestive cancers.

    Full Text Available Abstract Background This paper investigates the impact of geographic scale (census tract, zip code, and county on the detection of disparities in breast cancer mortality among three ethnic groups in Texas (period 1995-2005. Racial disparities were quantified using both relative (RR and absolute (RD statistics that account for the population size and correct for unreliable rates typically observed for minority groups and smaller geographic units. Results were then correlated with socio-economic status measured by the percentage of habitants living below the poverty level. Results African-American and Hispanic women generally experience higher mortality than White non-Hispanics, and these differences are especially significant in the southeast metropolitan areas and southwest border of Texas. The proportion and location of significant racial disparities however changed depending on the type of statistic (RR versus RD and the geographic level. The largest proportion of significant results was observed for the RD statistic and census tract data. Geographic regions with significant racial disparities for African-Americans and Hispanics frequently had a poverty rate above 10.00%. Conclusions This study investigates both relative and absolute racial disparities in breast cancer mortality between White non-Hispanic and African-American/Hispanic women at the census tract, zip code and county levels. Analysis at the census tract level generally led to a larger proportion of geographical units experiencing significantly higher mortality rates for minority groups, although results varied depending on the use of the relative versus absolute statistics. Additional research is needed before general conclusions can be formulated regarding the choice of optimal geographic regions for the detection of racial disparities.

  12. Adjusting a cancer mortality-prediction model for disease status-related eligibility criteria

    2011-05-01

    Full Text Available Abstract Background Volunteering participants in disease studies tend to be healthier than the general population partially due to specific enrollment criteria. Using modeling to accurately predict outcomes of cohort studies enrolling volunteers requires adjusting for the bias introduced in this way. Here we propose a new method to account for the effect of a specific form of healthy volunteer bias resulting from imposing disease status-related eligibility criteria, on disease-specific mortality, by explicitly modeling the length of the time interval between the moment when the subject becomes ineligible for the study, and the outcome. Methods Using survival time data from 1190 newly diagnosed lung cancer patients at MD Anderson Cancer Center, we model the time from clinical lung cancer diagnosis to death using an exponential distribution to approximate the length of this interval for a study where lung cancer death serves as the outcome. Incorporating this interval into our previously developed lung cancer risk model, we adjust for the effect of disease status-related eligibility criteria in predicting the number of lung cancer deaths in the control arm of CARET. The effect of the adjustment using the MD Anderson-derived approximation is compared to that based on SEER data. Results Using the adjustment developed in conjunction with our existing lung cancer model, we are able to accurately predict the number of lung cancer deaths observed in the control arm of CARET. Conclusions The resulting adjustment was accurate in predicting the lower rates of disease observed in the early years while still maintaining reasonable prediction ability in the later years of the trial. This method could be used to adjust for, or predict the duration and relative effect of any possible biases related to disease-specific eligibility criteria in modeling studies of volunteer-based cohorts.

    Full Text Available We examined individual-level and neighborhood-level predictors of mortality in CRC patients diagnosed in Florida to identify high-risk groups for targeted interventions.Demographic and clinical data from the Florida Cancer Data System registry (2007-2011 were linked with Agency for Health Care Administration and US Census data (n = 47,872. Cox hazard regression models were fitted with candidate predictors of CRC survival and stratified by age group (18-49, 50-64, 65+.Stratified by age group, higher mortality risk per comorbidity was found among youngest (21%, followed by middle (19%, and then oldest (14% age groups. The two younger age groups had higher mortality risk with proximal compared to those with distal cancer. Compared with private insurance, those in the middle age group were at higher death risk if not insured (HR = 1.35, or received healthcare through Medicare (HR = 1.44, Medicaid (HR = 1.53, or the Veteran's Administration (HR = 1.26. Only Medicaid in the youngest (52% higher risk and those not insured in the oldest group (24% lower risk were significantly different from their privately insured counterparts. Among 18-49 and 50-64 age groups there was a higher mortality risk among the lowest SES (1.17- and 1.23-fold higher in the middle age and 1.12- and 1.17-fold higher in the older age group, respectively compared to highest SES. Married patients were significantly better off than divorced/separated (HR = 1.22, single (HR = 1.29, or widowed (HR = 1.19 patients.Factors associated with increased risk for mortality among individuals with CRC included being older, uninsured, unmarried, more comorbidities, living in lower SES neighborhoods, and diagnosed at later disease stage. Higher risk among younger patients was attributed to proximal cancer site, Medicaid, and distant disease; however, lower SES and being unmarried were not risk factors in this age group.

    Diffusion is ubiquitous inside cells, and it is capable of inducing spontaneous pattern formation in reaction-diffusion systems on a spatially homogeneous domain. In this paper, we investigate the dynamics of a diffusive cancer network regulated by microRNA and obtain the condition that the network undergoes a Hopf bifurcation and a Turing pattern bifurcation. In addition, we also develop the amplitude equation of the network model by using Taylor series expansion, multi-scaling and further expansion in powers of a small parameter. As a result of these analyses, we obtain the explicit condition on how the dynamics of the diffusive cancer network evolve. These results reveal that this system has rich dynamics, such as spotted stripe and hexagon patterns. The bifurcation diagram helps us understand the biological mechanism in the cancer network. Finally, numerical simulations confirm our analytical results.

    Abstract We identified a set of genes with an unexpected bimodal distribution among breast cancer patients in multiple studies. The property of bimodality seems to be common, as these genes were found on multiple microarray platforms and in studies with different end-points and patient cohorts. Bimodal genes tend to cluster into small groups of four to six genes with synchronised expression within the group (but not between the groups), which makes them good candidates for robust conditional ...

  20. A cancer mortality study in Bombay-based atomic energy community: 1975-1987

    International Nuclear Information System (INIS)

    Cancer deaths recorded by the centralized health services of the Department of Atomic Energy (DAE) among its employees and their families stationed in Bombay during 1975-1987 have been analysed. Expected number of deaths due to cancer in the study group has been estimated by using the age -sex -specific cancer death rates reported for Bombay resident population for the year 1983. The size of the database for the entire DAE community is about 702,000 person years and the number of cancer deaths observed in 154. Analysis has been done separately for employees and their families, individually for important groups of cancer sites such as respiratory organs, digestive organs, breast, genito-urinary organs and lymphatic and haematopoietic systems. The standardised mortality ratios are generally lower than 100, which may partly be due to the 'healthy worker effect' in the DAE community and partly because of its differences in the social class distribution and the concomitant differences in lifestyle with respect to the comparison group of Bombay city.

    We analysed data from a cohort of 1966 subjects (889 men and 1,077 women) employed by an Italian asbestos (mainly textile) company in the period 1946-1984, who were followed-up to 2004. A total of 62,025 person-years of observation were recorded. We computed standardised mortality ratios (SMR) for all causes and selected cancer sites using national death rates for each 5-year calendar period and age group. There were 68 deaths from mesothelioma (25 men and 43 women, 39 pleural and 29 peritoneal) vs 1.6 expected (SMR=4,159), and 109 from lung cancer vs 35.1 expected (SMR=310). The SMRs of pleural/peritoneal cancer were 6661 for subjects exposed only before 30 years of age, 8,019 for those first exposed before 30 and still employed at 30-39 years of age and 5,786 for those first exposed before 30 and still employed at 40 or more years of age. The corresponding SMRs for lung cancer were 227, 446 and 562. The SMR of mesothelioma was strongly related to time since first exposure. The SMR of lung cancer, but not of mesothelioma, appeared to be related to subsequent exposures. PMID:17895892

  2. Age- and sex-specific mortality patterns in an emerging wildlife epidemic: the phocine distemper in European harbour seals.

    Directory of Open Access Journals (Sweden)

    Tero Härkönen

    Full Text Available Analyses of the dynamics of diseases in wild populations typically assume all individuals to be identical. However, profound effects on the long-term impact on the host population can be expected if the disease has age and sex dependent dynamics. The Phocine Distemper Virus (PDV caused two mass mortalities in European harbour seals in 1988 and in 2002. We show the mortality patterns were highly age specific on both occasions, where young of the year and adult (>4 yrs animals suffered extremely high mortality, and sub-adult seals (1-3 yrs of both sexes experienced low mortality. Consequently, genetic differences cannot have played a main role explaining why some seals survived and some did not in the study region, since parents had higher mortality levels than their progeny. Furthermore, there was a conspicuous absence of animals older than 14 years among the victims in 2002, which strongly indicates that the survivors from the previous disease outbreak in 1988 had acquired and maintained immunity to PDV. These specific mortality patterns imply that contact rates and susceptibility to the disease are strongly age and sex dependent variables, underlining the need for structured epidemic models for wildlife diseases. Detailed data can thus provide crucial information about a number of vital parameters such as functional herd immunity. One of many future challenges in understanding the epidemiology of the PDV and other wildlife diseases is to reveal how immune system responses differ among animals in different stages during their life cycle. The influence of such underlying mechanisms may also explain the limited evidence for abrupt disease thresholds in wild populations.

    Morality in Peninsular Malaysia has reached a level that is quite similar to that prevailing in the low mortality countries. This article systematically documents changes in mortality levels and differentials in Malaysia over time and relates these to changes in development indicators and health-related policies. Remedial measures undertaken by the authorities including the expansion of hospital and health services into the estates, together with a comprehensive malaria-eradication program, improvements in sanitation laws, and increased provision of public utilities and education, resulted in beriberi being eliminated and the incidence of malaria, typhus, and smallpox being greatly reduced by the time of World War II. The gain in life expectancy over the period of 1957-1979 was greatest for the Malay, the most significant period being 1957-1967, which saw the introduction of rural health programs. The infant mortality rate and the neonatal and post-neonatal rates declined substantially for all ethnic groups in Peninsular Malaysia for the same time period. Although the lower infant mortality of the Chinese can be explained by their advantageous socioeconomic position the same reason cannot explain the lower decline in infant mortality levels of the Indians. Much still needs to be done to narrow, if not to eliminate, the existing mortality differentials of different groups in the country. Overall, the quality of life of the general population can be further enhanced by reducing the high mortality level of disadvantaged groups. PMID:12341034

    The appropriateness of applying risk coefficients calculated from short-term exposures at high doses for the assessment of radiation effects at low doses is currently much debated. The problem can be resolved on the basis of the data obtained from a long-term follow-up of the population exposed in the early 1950s when discharges of radioactive wastes from a radiochemical plant into the Techa River (southern Urals) occurred. This paper discusses the results of an analysis of cancer mortality during the period 1950-82. 10 refs., 5 figs., 8 tabs.

The mass media and the population living on the romanian Danube's bank closed to Kozlodui - having still in mind the Chernobyl disaster - became more concerned about the possible health effects as a consequence of these events. On the other hand from the 1995 the cancer mortality in our country has an ascendant evolution. In this context the public health authority considered as a duty to pay attention to the possible influence of the Kozlodui Nuclear Power Plant on the local population health

  8. Radiation Therapy and Late Mortality From Second Sarcoma, Carcinoma, and Hematological Malignancies After a Solid Cancer in Childhood

    International Nuclear Information System (INIS)

    Purpose: To compare patterns of long-term deaths due to secondary carcinomas, sarcomas, and hematological malignancies occurring after childhood cancer in a cohort of patients followed over a median of 28 years. Methods and Materials: The study included 4,230 patients treated at eight institutions, who were at least 5-year survivors of a first cancer, representing 105,670 person-years of observation. Complete clinical, chemotherapeutic, and radiotherapeutic data were recorded, and the integral radiation dose was estimated for 2,701 of the 2,948 patients who had received radiotherapy. The integral dose was estimated for the volume inside the beam edges. The causes of death obtained from death certificates were validated. Results: In total, 134 events were due to second malignant neoplasm(s) (SMN). We found that the standardized mortality ratio decreased with increasing follow-up for second carcinomas and sarcomas, whereas the absolute excess risk (AER) increased for a second carcinoma but decreased for second sarcomas. There was no clear variation in SMN and AER for hematological malignancies. We found a significant dose-response relationship between the radiation dose received and the mortality rate due to a second sarcoma and carcinoma. The risk of death due to carcinoma and sarcoma as SMN was 5.2-fold and 12.5-fold higher, respectively, in patients who had received a radiation dose exceeding 150 joules. Conclusions: Among patients who had received radiotherapy, only those having received the highest integral radiation dose actually had a higher risk of dying of a second carcinoma or sarcoma.

    Full Text Available OBJECTIVES: To determine the main predictors of all-cause and cardiovascular (CV mortality in a rural West Indian population in Plymouth, Tobago over 30 years. METHODS: Questionnaire survey for CV risk factors and alcohol consumption patterns administered at baseline in 1976 with 92.5% response rate. 831/832 patients were followed up until 2005 or death. RESULTS: Hypertension (>140/90 mm Hg was prevalent in 48% of men and 44% of women, and 21% of men and 17% of women had diabetes. Evidence showed most predictors for all cause and cardiovascular mortality having the main effects at ages 160/95 mm Hg (HR 1.68, 95% CI 1.09-2.60, diabetes (HR 3.28, 95% CI 1.89-5.69, and BMI (HR 1.04, 95% CI 1.00-1.07. The main predictors of cardiovascular mortality were similar in the fully adjusted model: high sessional alcohol intake (HR 2.47 95% CI 1.10-5.57, severe hypertension (HR 2.78 95% CI 1.56-4.95, diabetes (HR 3.68 95% CI 1.77-7.67 and additionally LVH, (HR 5.54 95% CI 1.38-22.26, however BMI did not show independent effects. For men, high sessional alcohol intake explains 27% of all cause mortality, and 40% of cardiovascular mortality at age <60 yrs. In adults aged <60 years, the attributable risk fraction for IGT/Diabetes and all cause mortality and cardiovascular mortality is 28% in women vs. 11% in men, and 22% in women vs. 6% in men respectively. CONCLUSIONS: In this Afro-Caribbean population we found that a major proportion of deaths are attributable to high sessional alcohol intake (in males, diabetes, and hypertension and these risk factors primarily operate in those below 60 years.

  10. Comparison of mortality outcomes after radical prostatectomy versus radiotherapy in patients with localized prostate cancer. A population-based analysis

    International Nuclear Information System (INIS)

    The objectives of this study were to compare the mortality outcomes of radical prostatectomy and radiotherapy as treatment modalities for patients with localized prostate cancer. Our cohort consisted of 68 665 patients with localized prostate cancer, treated with radical prostatectomy or radiotherapy, between 1992 and 2005. Propensity-score matching was used to minimize potential bias related to treatment assignment. Competing-risks analyses tested the effect of treatment type on cancer-specific mortality, after accounting for other-cause mortality. All analyses were stratified according to prostate cancer risk groups, baseline Charlson Comorbidity Index and age. For patients treated with radical prostatectomy versus radiotherapy, the 10-year cancer-specific mortality rates were 1.4 versus 3.9% in low-intermediate risk prostate cancer and 6.8 versus 11.5% in high-risk prostate cancer, respectively. Rates were 2.4 versus 5.9% in patients with Charlson Comorbidity Index of 0, 2.4 versus 5.1% in patients with Charlson Comorbidity Index of 1, and 2.9 versus 5.2% in patients with Charlson Comorbidity Index of ≥2. Rates were 2.1 versus 5.0% in patients aged 65-69 years, 2.8 versus 5.5% in patients aged 70-74 years, and 2.9 versus 7.6% in patients aged 75-80 years (all P<0.001). At multivariable analyses, radiotherapy was associated with less favorable cancer-specific mortality in all categories (all P<0.001). Patients treated with radical prostatectomy fare substantially better than those treated with radiotherapy. Patients with high-risk prostate cancer benefit the most from radical prostatectomy. Conversely, the lowest benefit was observed in patients with low-intermediate risk prostate cancer and/or multiple comorbidities. An intermediate benefit was observed in the other examined categories. (author)

    2016-01-01

    Investigating epidemiology of metastatic colon and rectal cancer is challenging, because cancer registries seldom record metastatic sites. We used a population based approach to assess metastatic spread in colon and rectal cancers. 49,096 patients with colorectal cancer were identified from the nationwide Swedish Cancer Registry. Metastatic sites were identified from the National Patient Register and Cause of Death Register. Rectal cancer more frequently metastasized into thoracic organs (OR = 2.4) and the nervous system (1.5) and less frequently within the peritoneum (0.3). Mucinous and signet ring adenocarcinomas more frequently metastasized within the peritoneum compared with generic adenocarcinoma (3.8 [colon]/3.2 [rectum]), and less frequently into the liver (0.5/0.6). Lung metastases occurred frequently together with nervous system metastases, whereas peritoneal metastases were often listed with ovarian and pleural metastases. Thoracic metastases are almost as common as liver metastases in rectal cancer patients with a low stage at diagnosis. In colorectal cancer patients with solitary metastases the survival differed between 5 and 19 months depending on T or N stage. Metastatic patterns differ notably between colon and rectal cancers. This knowledge should help clinicians to identify patients in need for extra surveillance and gives insight to further studies on the mechanisms of metastasis. PMID:27416752

    2012-01-01

    We document causes of death in free-ranging California Condors (Gymnogyps californianus) from the inception of the reintroduction program in 1992 through December 2009 to identify current and historic mortality factors that might interfere with establishment of self-sustaining populations in the wild. A total of 135 deaths occurred from October 1992 (the first post-release death) through December 2009, from a maximum population-at-risk of 352 birds, for a cumulative crude mortality rate of 38%. A definitive cause of death was determined for 76 of the 98 submitted cases, 70% (53/76) of which were attributed to anthropogenic causes. Trash ingestion was the most important mortality factor in nestlings (proportional mortality rate [PMR] 73%; 8/11), while lead toxicosis was the most important factor in juveniles (PMR 26%; 13/50) and adults (PMR 67%; 10/15). These results demonstrate that the leading causes of death at all California Condor release sites are anthropogenic. The mortality factors thought to be important in the decline of the historic California Condor population, particularly lead poisoning, remain the most important documented mortality factors today. Without effective mitigation, these factors can be expected to have the same effects on the sustainability of the wild populations as they have in the past.

    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

All cases were followed for vital status following QoL assessment, and mortality was analyzed with Cox proportional hazards regression.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.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 everyday tasks and are associated with

    Full Text Available BACKGROUND: A Mediterranean diet has a recognized beneficial effect on health and longevity, with a protective influence on several cancers. However, its association with breast cancer risk remains unclear. OBJECTIVE: We aimed to investigate whether adherence to a Mediterranean dietary pattern influences breast cancer risk. DESIGN: The Swedish Women's Lifestyle and Health cohort study includes 49,258 women aged 30 to 49 years at recruitment in 1991-1992. Consumption of foods and beverages was measured at enrollment using a food frequency questionnaire. A Mediterranean diet score was constructed based on the consumption of alcohol, vegetables, fruits, legumes, cereals, fish, the ratio of unsaturated to saturated fat, and dairy and meat products. Relative risks (RR for breast cancer and specific tumor characteristics (invasiveness, histological type, estrogen/progesterone receptor status, malignancy grade and stage associated with this score were estimated using Cox regression controlling for potential confounders. RESULTS: 1,278 incident breast cancers were diagnosed. Adherence to a Mediterranean dietary pattern was not statistically significantly associated with reduced risk of breast cancer overall, or with specific breast tumor characteristics. A RR (95% confidence interval for breast cancer associated with a two-point increment in the Mediterranean diet score was 1.08 (1.00-1.15 in all women, and 1.10 (1.01-1.21 and 1.02 (0.91-1.15 in premenopausal and postmenopausal women, respectively. When alcohol was excluded from the Mediterranean diet score, results became not statistically significant. CONCLUSIONS: Adherence to a Mediterranean dietary pattern did not decrease breast cancer risk in this cohort of relatively young women.

    Full Text Available Abstract Background Hexavalent chromium is a known carcinogen when inhaled, but its carcinogenic potential when orally ingested remains controversial. Water contaminated with hexavalent chromium is a worldwide problem, making this a question of significant public health importance. Methods We conducted an ecological mortality study within the Oinofita region of Greece, where water has been contaminated with hexavalent chromium. We calculated gender, age, and period standardized mortality ratios (SMRs for all deaths, cancer deaths, and specific cancer types of Oinofita residents over an 11-year period (1999 - 2009, using the greater prefecture of Voiotia as the standard population. Results A total of 474 deaths were observed. The SMR for all cause mortality was 98 (95% CI 89-107 and for all cancer mortality 114 (95% CI 94-136. The SMR for primary liver cancer was 1104 (95% CI 405-2403, p-value Conclusions Elevated cancer mortality in the Oinofita area of Greece supports the hypothesis of hexavalent chromium carcinogenicity via the oral ingestion pathway of exposure. Further studies are needed to determine whether this association is causal, and to establish preventive guidelines and public health recommendations.

    Full Text Available BACKGROUND: Known associations between diabetes and cancer could logically be attributed to hyperglycemia, hypersecretion of insulin, and/or insulin resistance. This study examined the relationship between initial glycemic biomarkers among men and women with impaired fasting glucose or undiagnosed diabetes and cancer mortality during follow up. METHODS: The cohort included subjects aged 40 years and above from the Third National Health and Nutrition Examination Survey (NHANES III with fasted serum glucose >100 mg/dl without the aid of pharmaceutical intervention (insulin or oral hypoglycemics. Cancer mortality was obtained from the NHANES III-linked follow-up database (up to December 31, 2006. A Cox regression model was applied to test for the associations between cancer mortality and fasting serum glucose, insulin, glycosylated hemoglobin (HbA1c, C-peptide, insulin like growth factor (IGF-1, IGF binding protein 3 (IGFBP3 and estimated insulin resistance. RESULTS: A total of 158 and 100 cancer deaths were recorded respectively from 1,348 men and 1,161 women during the mean 134-month follow-up. After adjusting for the effect of age and smoking in women, all-cause cancer deaths (HR: 1.96 per pmol/ml, 95% CI: 1.02-3.77 and lung cancer deaths (HR: 2.65 per pmol/ml, 95% CI: 1.31-5.36 were specifically associated with serum C-peptide concentrations. Similar associations in men were not statistically significant. Serum glucose, HbA1c, IGF-1, IGFBP3 and HOMA were not independently related to long-term cancer mortality. CONCLUSION: C-peptide analyses suggest a modest association with both all-cause and lung cancer mortality in women but not in men. Further studies will be required to explore the mechanisms.

    Full Text Available Prostate cancer mortality projections at the nationwide and regional levels to the year 2025 are carried out in this ecological study that is based on an analysis of Brazilian trends between 1996 and 2010. The predictions were made for the period 2011-2025 utilizing the Nordpred program based on the period of 1996-2010, using the age-period-cohort model. A significant increase was observed in the Brazilian rates between 1996 and 2006, followed by a non-significant decrease. The projections indicate a decrease in rates at a national level as well as for the Central, South and Southeast regions. Increases are expected for the North and Northeast regions. In conclusion, a reduction in the mortality rates for prostate cancer in Brazil is expected to the year 2025, as well as for the Central, South and Southeast regions. However, an increase in the absolute number of deaths in all regions is expected due to the anticipated aging of the population.

  3. Cancer mortality among a group of fluorspar miners exposed to radon progeny

    International Nuclear Information System (INIS)

    A cohort study of the mortality experience (1950-1984) of 1,772 Newfoundland underground fluorspar miners occupationally exposed to high levels of radon daughters (mean dose = 382.8 working levels months) has been conducted. Observed numbers of cancers of the lung, salivary gland, and buccal cavity and pharynx were significantly elevated among these miners. A highly significant relation was noted between radon daughter exposure and risk of dying of lung cancer; the small numbers of salivary gland (n = 2) and buccal cavity and pharynx (n = 6) cancers precluded meaningful analysis of dose response. Attributable and relative risk coefficients for lung cancer were estimated as 6.3 deaths per working level month per million person-years and 0.9% per working level month, respectively. Relative risk coefficients were highest for those first exposed before age 20 years. Cigarette smokers had relative and attributable risk coefficients comparable to those of nonsmokers. Relative risks fell sharply with age, whereas attributable risks were lowest in the youngest and oldest age groups. The results suggest that efforts to raise existing occupational exposure standards may be inappropriate

    Full Text Available Abstract Background Myocardial infarction can be difficult to diagnose after lung surgery. As recent diagnostic criteria emphasize serum cardiac markers (in particular serum troponin we set out to evaluate its clinical utility and to establish the long term prognostic impact of detected abnormal postoperative troponin levels after lung resection. Methods We studied a historic cohort of patients with primary lung cancer who underwent intended surgical resection. Patients were grouped according to known postoperative troponin status and survival calculated by Kaplan Meier method and compared using log rank. Parametric survival analysis was used to ascertain independent predictors of mortality. Results From 2001 to 2004, a total of 207 patients underwent lung resection for primary lung cancer of which 14 (7% were identified with elevated serum troponin levels within 30 days of surgery, with 9 (64% having classical features of myocardial infarction. The median time to follow up (interquartile range was 22 (1 to 52 months, and the one and five year survival probabilities (95% CI for patients without and with postoperative troponin elevation were 92% (85 to 96 versus 60% (31 to 80 and 61% (51 to 71 versus 18% (3 to 43 respectively (p T stage and postoperative troponin elevation remained independent predictors of mortality in the final multivariable model. The acceleration factor for death of elevated serum troponin after adjusting for tumour stage was 9.19 (95% CI 3.75 to 22.54. Conclusion Patients with detected serum troponin elevation are at high risk of early mortality with or without symptoms of myocardial infarction after lung resection.

  5. Mortality from breast cancer after irradiation during fluoroscopic examinations in patients being treated for tuberculosis

    International Nuclear Information System (INIS)

    The increasing use of mammography to screen asymptomatic women makes it important to know the risk of breast cancer associated with exposure to low levels of ionizing radiation. We examined the mortality from breast cancer in a cohort of 31,710 women who had been treated for tuberculosis at Canadian sanatoriums between 1930 and 1952. A substantial proportion (26.4 percent) had received radiation doses to the breast of 10 cGy or more from repeated fluoroscopic examinations during therapeutic pneumothoraxes. Women exposed to greater than or equal to 10 cGy of radiation had a relative risk of death from breast cancer of 1.36, as compared with those exposed to less than 10 cGy (95 percent confidence interval, 1.11 to 1.67; P = 0.001). The data were most consistent with a linear dose-response relation. The risk was greatest among women who had been exposed to radiation when they were between 10 and 14 years of age; they had a relative risk of 4.5 per gray, and an additive risk of 6.1 per 10(4) person-years per gray. With increasing age at first exposure, there was substantially less excess risk, and the radiation effect appeared to peak approximately 25 to 34 years after the first exposure. Our additive model for lifetime risk predicts that exposure to 1 cGy at the age of 40 increases the number of deaths from breast cancer by 42 per million women. We conclude that the risk of breast cancer associated with radiation decreases sharply with increasing age at exposure and that even a small benefit to women of screening mammography would outweigh any possible risk of radiation-induced breast cancer

    2010-03-01

    Full Text Available Abstract Background Accurate nationally representative statistics on total and cause-specific mortality in Vietnam are lacking due to incomplete capture in government reporting systems. This paper presents total and cause-specific mortality results from a national verbal autopsy survey conducted first time in Vietnam in conjunction with the annual population change survey and discusses methodological and logistical challenges associated with the implementation of a nation-wide assessment of mortality based on surveys. Verbal autopsy interviews, using the WHO standard questionnaire, were conducted with close relatives of the 6798 deaths identified in the 2007 population change survey in Vietnam. Data collectors were health staff recruited from the commune health station who undertook 3-day intensive training on VA interview. The Preston-Coale method assessed the level of completeness of mortality reporting from the population change survey. The number of deaths in each age-sex grouping is inflated according to the estimate of completeness to produce an adjusted number of deaths. Underlying causes of death were aggregated to the International Classification of Diseases Mortality Tabulation List 1. Leading causes of death were tabulated by sex for three broad age groups: 0-14 years; 15-59 years; and 60 years and above. Findings Completeness of mortality reporting was 69% for males and 54% for females with substantial regional variation. The use of VA has resulted in 10% of deaths being classified to ill-defined among males, and 15% among females. More ill-defined deaths were reported among the 60 year or above age group. Incomplete death reporting, wide geographical dispersal of deaths, extensive travel between households, and substantial variation in local responses to VA interviews challenged the implementation of a national mortality and cause of death assessment based on surveys. Conclusions Verbal autopsy can be a viable tool to identify cause

  8. Patterns and causes of neonatal and postneonatal mortality in rural Bangladesh.

    1989-01-01

    Community-level research data from a Maternal-Child Health and Family Planning (MCH/FP) program and comparison areas in rural Bangladesh indicate that 60 percent of infant deaths occurred in the neonatal period in both areas. Since the inception of the MCH/FP program, mortality rates declined relative to those in the comparison area. This decline, however, was confined to the neonatal period death rates only, with mortality rates in the postneonatal period remaining similar in the two areas. Prematurity accounted for approximately 40 percent of deaths in the neonatal period. Cause-of-death data indicated that the differences in the neonatal mortality rates between the two areas was mainly due to a marked decline in tetanus neonatorum deaths in the MCH/FP program area, because of the tetanus toxoid immunization of pregnant women there. The interventions in the MCH/FP area, however, did not significantly influence mortality due to any other cause. This study provides an explanation for the limited impact on infant mortality of health interventions that focus on diarrheal diseases and immunizations of children. PMID:2734810

    Additive and multiplicative models of relative risk were used to measure the effect of cancer misclassification and DS86 random errors on lifetime risk projections in the Life Span Study (LSS) of Hiroshima and Nagasaki atomic bomb survivors. The true number of cancer deaths in each stratum of the cancer mortality cross-classification was estimated using sufficient statistics from the EM algorithm. Average survivor doses in the strata were corrected for DS86 random error ({sigma}=0.45) by use of reduction factors. Poisson regression was used to model the corrected and uncorrected mortality rates with risks in RERF Report 11 (Part 2) and the BEIR-V Report. Bias due to DS86 random error typically ranged from {minus}15% to {minus}30% for both sexes, and all sites and models. The total bias, including diagnostic misclassification, of excess risk of nonleukemia for exposure to 1 Sv from age 18 to 65 under the non-constant relative project model was {minus}37.1% for males and {minus}23.3% for females. Total excess risks of leukemia under the relative projection model were biased {minus}27.1% for males and {minus}43.4% for females. Thus, nonleukemia risks for 1 Sv from ages 18 to 65 (DRREF=2) increased from 1.91%/Sv to 2.68%/Sv among males and from 3.23%/Sv to 4.92%/Sv among females. Leukemia excess risk increased from 0.87%/Sv to 1.10/Sv among males and from 0.73%/Sv to 1.04/Sv among females. Bias was dependent on the gender, site, correction method, exposure profile and projection model considered. Future studies that use LSS data for US nuclear workers may be downwardly biased if lifetime risk projections are not adjusted for random and systematic errors.

    Full Text Available BACKGROUND: In this manuscript, we assessed tumor recurrence and tumor-related mortality in a clinical series of endometrial cancer patients. MATERIALS AND METHODS: A retrospective evaluation of 276 patients (mean age 64 years with histologically confirmed endometrial cancer treated at a single hospital in Madrid (Spain was conducted. The median follow-up was estimated using the inverse Kaplan–Meier method. RESULTS: Salient findings were endometrioid carcinoma (84.8% of cases, grade G1 (48.9% and stages IB (35.1% and IC (23.2%. Myometrial infiltration >50% was documented in 31.2% of cases and lymphovascular space invasion in 11.9%. After surgery, 52.5% of patients were classified into the low risk group, 21.4% into the intermediate risk group and 26.1% into the high risk group. Tumor recurrence occurred in 14.5% of patients, with an estimated median follow-up of 45 months (95% confidence interval (CI: 41.2–48.8, locoregional recurrence in 42.5% and distant recurrences in 57.5%. Furthermore, 40% of tumor recurrences developed during the first year after primary treatment and 90% over the first 3 years of follow-up. The tumor-related mortality rate was 15.9%. The estimated median follow-up was 46 months (95% CI: 43.0–49.0. Furthermore, 5.07% of death because of tumor developed during the first year after primary treatment and 13.77% over the first 3 years of follow-up. CONCLUSION: The rates of tumor-related death and tumor recurrence in endometrial cancer patients are low, with the highest percentages occurring within 3 years of primary treatment. Most of the recurrences occur outside the pelvis.

The true number of cancer deaths in each stratum of the cancer mortality cross-classification was estimated using sufficient statistics from the EM algorithm. Average survivor doses in the strata were corrected for DS86 random error (σ = 0.45) by use of reduction factors. Poisson regression was used to model the corrected and uncorrected mortality rates with covariates for age at-time-of-bombing, age at-time-of-death and gender. Excess risks were in good agreement with risks in RERF Report 11 (Part 2) and the BEIR-V report. Bias due to DS86 random error typically ranged from -15% to -30% for both sexes, and all sites and models. The total bias, including diagnostic misclassification, of excess risk of nonleukemia for exposure to 1 Sv from age 18 to 65 under the non-constant relative projection model was -37.1% for males and -23.3% for females. Total excess risks of leukemia under the relative projection model were biased -27.1% for males and -43.4% for females.

  16. Long-term mortality from cardiac causes after adjuvant hypofractionated vs. conventional radiotherapy for localized left-sided breast cancer

    International Nuclear Information System (INIS)

    Background and purpose: Ongoing concern remains regarding cardiac injury with hypofractionated whole breast/chest-wall radiotherapy (HF-WBI) compared to conventional radiotherapy (CF-WBI) in left-sided breast cancer patients. The purpose was to determine if cardiac mortality increases with HF-WBI relative to CF-WBI. Materials and methods: Between 1990 and 1998, 5334 women with early-stage breast cancer received post-operative radiotherapy to the breast/chest wall alone. A population-based database recorded baseline patient, tumor and treatment factors. Baseline cardiovascular risk factors were identified from hospital administrative records. A propensity-score model balanced risk factors between radiotherapy groups. Cause of death was coded as breast cancer, cardiac or other cause. Cumulative mortality from each cause after radiotherapy was estimated using a competing risk approach. Results: For left-sided cases, median follow-up was 14.2 years. 485 women received CF-WBI, 2221 women received HF-WBI. There was no difference in 15-year mortality from cardiac causes: 4.8% with HF-WBI and 4.2% with CF-WBI (p = 0.74), even after propensity-score adjustment (p = 0.45). There was no difference in breast cancer mortality or other cause mortality. For right-sided cases, there was no difference in mortality for the three causes of death. Conclusions: At 15-years follow-up, cardiac mortality is not statistically different among left-sided breast cancer patients treated with HF-WBI or CF-WBI

  17. Perineural invasion associated with increased cancer-specific mortality after external beam radiation therapy for men with low- and intermediate-risk prostate cancer

    International Nuclear Information System (INIS)

    Purpose: To identify an association between perineural invasion (PNI) and cancer-specific survival in patients with prostate cancer after standard-dose external beam radiation therapy (RT). Methods and Materials: A total of 517 consecutive patients who underwent RT (median dose, 70.5 Gy) between 1989 and 2003 for low-risk or intermediate-risk prostate cancer were studied. A genitourinary pathologist (AAR) scored presence or absence of PNI on all prostate needle-biopsy specimens. A Cox regression multivariable analysis was performed to assess whether the presence of PNI was associated with risk of prostate cancer-specific mortality after RT when the recognized risk-group variables were factored into the model. Estimates of cancer-specific mortality were made using a cumulative incidence method. Comparisons of survival were made using a two-tailed log-rank test. Results: At a median follow-up of 4.5 years, 84 patients (16%) have died, 15 of 84 (18%) from prostate cancer. PNI was the only significant predictor of prostate cancer-specific mortality after RT (p = 0.012). The estimated prostate cancer-specific mortality was 14% at 8 years for PNI+ patients vs. 5% for PNI- patients (p = 0.0008). Conclusions: Patients with low- or intermediate-risk prostate cancer who have PNI on prostate needle biopsy have a significantly higher rate of prostate cancer-specific mortality after standard-dose radiation therapy than patients without PNI. Although this analysis is retrospective, this association argues for consideration of the use of more aggressive therapy, such as hormonal therapy with RT or dose escalation, in these select patients

    Full Text Available Abstract Background Spatial clustering of different diseases has received much less attention than single disease mapping. Besides chance or artifact, clustering of different cancers in a given area may depend on exposure to a shared risk factor or to multiple correlated factors (e.g. cigarette smoking and obesity in a deprived area. Models developed so far to investigate co-occurrence of diseases are not well-suited for analyzing many cancers simultaneously. In this paper we propose a simple two-step exploratory method for screening clusters of different cancers in a population. Methods Cancer incidence data were derived from the regional cancer registry of Umbria, Italy. A cluster analysis was performed on smoothed and non-smoothed standardized incidence ratios (SIRs of the 13 most frequent cancers in males. The Besag, York and Mollie model (BYM and Poisson kriging were used to produce smoothed SIRs. Results Cluster analysis on non-smoothed SIRs was poorly informative in terms of clustering of different cancers, as only larynx and oral cavity were grouped, and of characteristic patterns of cancer incidence in specific geographical areas. On the other hand BYM and Poisson kriging gave similar results, showing cancers of the oral cavity, larynx, esophagus, stomach and liver formed a main cluster. Lung and urinary bladder cancers clustered together but not with the cancers mentioned above. Both methods, particularly the BYM model, identified distinct geographic clusters of adjacent areas. Conclusion As in single disease mapping, non-smoothed SIRs do not provide reliable estimates of cancer risks because of small area variability. The BYM model produces smooth risk surfaces which, when entered into a cluster analysis, identify well-defined geographical clusters of adjacent areas. It probably enhances or amplifies the signal arising from exposure of more areas (statistical units to shared risk factors that are associated with different cancers. In

    Full Text Available Abstract Background Cervical cancer is the most common cancer experienced by women worldwide; however, screening techniques are very effective for reducing the risk of death. The national cervical cancer screening program was implemented in Taiwan in 1995. The objective of this study was to examine and provide evidence of the cervical cancer mortality trends for the periods before and after the screening program was implemented. Methods Data from 1981 to 2010 of the causes of death registered were obtained from the Department of Health, Taiwan. Age-standardized mortality rates, age-specific rates, and age-period-cohort models that employed the sequential method were used to assess temporal changes that occurred between 1981 and 2010, with 1995 used as the separating year. Results The results showed that for both time periods of 1981 to 1995 and 1996 to 2010, age and period had significant effects, whereas the birth cohort effects were insignificant. For patients between 80 and 84 years of age, the mortality rate for 1981 to 1995 and 1996 to 2010 was 48.34 and 68.08. The cervical cancer mortality rate for 1996 to 2010 was 1.0 for patients between 75 and 79 years of age and 1.4 for patients between 80 and 84 years of age compared to that for 1981 to 1995. Regarding the period effect, the mortality trend decreased 2-fold from 1996 to 2010. Conclusions The results of this study indicate a decline in cervical cancer mortality trends after the screening program involving Papanicolaou tests was implemented in 1995. However, the positive effects of the screening program were not observed in elderly women because of treatment delays during the initial implementation of the screening program.

  20. Estrogen receptor testing and 10-year mortality from breast cancer: A model for determining testing strategy

    Full Text Available Background: The use of adjuvant tamoxifen therapy in the treatment of estrogen receptor (ER expressing breast carcinomas represents a major advance in personalized cancer treatment. Because there is no benefit (and indeed there is increased morbidity and mortality associated with the use of tamoxifen therapy in ER-negative breast cancer, its use is restricted to women with ER expressing cancers. However, correctly classifying cancers as ER positive or negative has been challenging given the high reported false negative test rates for ER expression in surgical specimens. In this paper I model practice recommendations using published information from clinical trials to address the question of whether there is a false negative test rate above which it is more efficacious to forgo ER testing and instead treat all patients with tamoxifen regardless of ER test results. Methods: I used data from randomized clinical trials to model two different hypothetical treatment strategies: (1 the current strategy of treating only ER positive women with tamoxifen and (2 an alternative strategy where all women are treated with tamoxifen regardless of ER test results. The variables used in the model are literature-derived survival rates of the different combinations of ER positivity and treatment with tamoxifen, varying true ER positivity rates and varying false negative ER testing rates. The outcome variable was hypothetical 10-year survival. Results: The model predicted that there will be a range of true ER rates and false negative test rates above which it would be more efficacious to treat all women with breast cancer with tamoxifen and forgo ER testing. This situation occurred with high true positive ER rates and false negative ER test rates in the range of 20-30%. Conclusions: It is hoped that this model will provide an example of the potential importance of diagnostic error on clinical outcomes and furthermore will give an example of how the effect of that

    The main objective of this paper was to identify possible acute heat-induced summer mortality in five regions of England namely the Yorkshire and the Humber, West Midlands, North East, North West and South East regions and reveal associations with specific air flows. For this purpose, backward air mass trajectories corresponding to daily episodes of increased temperatures were produced and divided to clusters, in order to define atmospheric pathways associated with warm air mass intrusions. A statistically significant at 95 % confidence interval increase in daily total mortality (DTMORT) was observed during the selected episodes at all five regions and thus, heat-induced mortality was indicated. The calculated raise was more intense in the West Midlands, North West and South East regions, whereas the results in the North East and Yorkshire and the Humber regions were less evident. Large fractions of thermal episodes, elevated average temperature values and higher average DTMORT levels were primarily associated with the short-medium range South West (SW) and/or East-South East (E-SE) trajectory clusters, suggesting relations among heat-induced mortality and specific atmospheric circulations. Short-medium length of SW and E-SE airflows, calculated by an application of Haversine formula along the centroid trajectory of each cluster, implies the arrival of slow moving air masses. Atmospheric stagnation could enhance human thermal stress due to low wind speed. PMID:25605407

    Our aim was to determine the effect of a national strategy for quality improvement in cancer management (the "Plan Cancer") according to time period and to assess the influence of type and volume of hospital activity on in-hospital mortality (IHM) within a large national cohort of patients operated on for lung cancer.From January 2005 to December 2013, 76 235 patients were included in the French Administrative Database. Patient characteristics, hospital volume of activity and hospital type were analysed over three periods: 2005-2007, 2008-2010 and 2011-2013.Global crude IHM was 3.9%: 4.3% during 2005-2007, 4% during 2008-2010 and 3.5% during 2011-2013 (p43 resections per year (adjusted (a)OR 1.48, 95% CI 1.197-1.834). The risk of death was lower in the period 2011-2013 than in the period 2008-2010 (aOR 0.841, 95% CI 0.764-0.926). Adjustment variables (age, sex, Charlson score and type of resection) were significantly linked to IHM, whereas the type of hospital was not.The French national strategy for quality improvement seems to have induced a significant decrease in IHM.

    Between 1998-2002, 16,952 new cases of cancer were registered in Navarre. In men, the most frequently diagnosed cancers were in the following order: prostate, lung, colon and rectum, bladder and stomach, which accounted for 63.2%. In women, the sites were breast, colon and rectum, corpus uteri, stomach and ovary, which accounted for 57.6% of the cases. In the same period, 1998-2002, 4,127 men and 2,470 women died from cancer. Sixty percent of all deaths due to malign tumours in men were due to cancer of the lung, prostate, colon and rectum, stomach and bladder. In women this was due to cancers of colon and rectum, breast, stomach, pancreas and lung, which accounted for 49% of the cases. In men in Navarre there has been an increase in the incidence rates of cancer of the prostate, kidney and non-Hodgkin lymphoma. Avoidable cancers such as those related to smoking (lung, oral cavity and pharynx or pancreas) continue to rise, and represent a greater global risk of dying from cancer in the latest period studied than in the decades of the 1970s and 1980s. From 1995 up to the present, mortality due to cancer has moved from occupying the second place to become the first cause of death among men in Navarre. The global risk of death due to cancer in men is now equal to the first period studied, 1975-1977. Amongst women the global risk of death due to cancer fell by 25% between 1975 and 2002, basically at the cost of breast and stomach cancer. Tumours related to smoking increased both in mortality and in incidence and appear as a significant health problem amongst women in Navarre. Breast cancer has increased in incidence, with lower mortality figures than those of the first period 1975-1977. Invasive cancer of the cervix remains at very low rates in comparison with many European countries, including Spain. In both sexes colorectal and skin cancer has increased, while the incidence and mortality of stomach cancer continues to fall. PMID:17898820

    This study aimed to describe severe infections with extensively drug-resistant Acinetobacter baumannii-calcoaceticus complex (XDR-ABC), as well as to investigate risk factors for mortality, in cancer patients. It was a retrospective study including all patients diagnosed with XDR-ABC bacteraemia during hospitalization in the intensive care unit of a cancer hospital between July 2009 and July 2013. Surveillance cultures were collected weekly during the study period, and clonality was analysed using pulsed field gel electrophoresis (PFGE). We analysed underlying diseases, oncology therapy, neutrophil counts, infection site and management of infection, in terms of their correlation with 30-day mortality. During the study period, 92 patients with XDR-ABC bacteraemia were identified, of whom 35 (38.0%) were patients with haematological malignancy. We identified XDR-ABC strains with four different profile patterns, 91.3% of patients harbouring the predominant PFGE type. Of the 92 patients with XDR-ABC bacteraemia, 66 (71.7%) had central line-associated bloodstream infections; infection occurred during neutropenia in 22 (23.9%); and 58 (63.0%) died before receiving the appropriate therapy. All patients were treated with polymyxin, which was used in combination therapy in 30 of them (32.4%). The 30-day mortality rate was 83.7%. Multivariate analysis revealed that septic shock at diagnosis of XDR-ABC infection was a risk factor for 30-day mortality; protective factors were receiving appropriate therapy and invasive device removal within the first 48 h. Among cancer patients, ineffective management of such infection increases the risk of death, more so than do features such as neutropenia and infection at the tumour site. PMID:26711434

    Full Text Available The relationship between the ever-increasing cancer mortality and water pollution is an important public concern in China. This study aimed to explore the association between serious water pollution and increasing digestive cancer mortality in the Huai River Basin (HRB in China. A series of frequency of serious pollution (FSP indices including water quality grade (FSPWQG, biochemical oxygen demand (FSPBOD, chemical oxygen demand (FSPCOD, and ammonia nitrogen (FSPAN were used to characterize the surface water quality between 1997 and 2006. Data on the county-level changing mortality (CM due to digestive tract cancers between 1975 and 2006 were collected for 14 counties in the study area. Most of investigated counties (eight with high FSPWQG (>50% distributed in the northern region of the HRB and had larger CMs of digestive tract cancers. In addition to their similar spatial distribution, significant correlations between FSP indices and CMs were observed by controlling for drinking water safety (DWS, gross domestic product (GDP, and population (POP. Furthermore, the above-mentioned partial correlations were clearly increased when only controlling for GDP and POP. Our study indicated that county-level variations of digestive cancer mortality are remarkably associated with water pollution, and suggested that continuous measures for improving surface water quality and DWS and hygienic interventions should be effectively implemented by local governments.

    To determine whether there was excessive risk of cancer among workers exposed to chrysotile fiber alone by applying a meta-analysis technique. Methods All data meeting the criteria of cohort studies on cancer mortality among workers exposed only to chrysotile were incorporated into meta-analysis. Pooled standardized mortality ratios (SMRs) and their corresponding 95% confidence intervals (CIs) for main cancer sites were calculated using two approaches of unweighted ratio and random effect model. The heterogeneity and its sources of the results were examined with a Q-statistic and Z-score test. The dose-response effect as reflected in the percentage of all deaths due to mesothelioma served as a proxy measure of chrysotile exposure. Results A cohort of twenty six workers exposed to chrysotile alone was summarized. The significantly elevated meta-SMRs for all deaths (1.27), all cancers (1.28), cancers of respiratory organs (2.51), cancers of lung (2.35) and cancers of stomach (1.24) were observed. The significantly elevated meta-SMRs for lung cancer within occupational strata were observed among textile workers (3.55), asbestos product manufacturers (3.30), miners and millers (2.24), cement product workers (1.22), and for stomach cancer among asbestos product manufacturers (1.49). Meta-SMRs for cancers at other sites were not significant. Meta-SMR for lung cancer showed an increasing trend with an elevated percentage of all deaths from mesothelioma, but no such trend for stomach cancer. Conclusion There are excessive risks of lung cancer and mesothelioma among workers exposed to chrysotile fiber alone, and likely no convincing indication of an etiological association between chrysotile exposure and cancers at other sites.

    Full Text Available Data mining techniques are used for the knowledge discovery process under the large data set environment. Clustering techniques are used to group up the relevant data sets. Hierarchical and partitioned clustering techniques are used for the clustering process. The clustering process is the complex task with high process time. The pattern extraction scheme is applied to find frequent item sets. Association rule mining techniques are applied to carry out the pattern extraction process. The pattern extraction scheme and the clustering scheme are integrated in the simultaneous pattern extraction and clustering scheme. The clustering process is improved with pattern comparison and transaction transfer process. The simultaneous clustering scheme is implemented to analyze the cancer patient diagnosis reports. The system is implemented as four major modules data set management, pattern extraction, clustering process and performance analysis. The data sets are preprocessed before the pattern extraction process. The patterns are used in the simultaneous clustering process. The performance analysis is done with the comparison of the data clustering scheme and pattern clustering schemes. The process time and memory factors are used in the performance analysis process. The cluster accuracy is represented using the fitness values. The system is enhanced with the K-means clustering algorithm.

    This is a review of hypnotic drug risks and benefits, reassessing and updating advice presented to the Commissioner of the Food and Drug Administration (United States FDA). Almost every month, new information appears about the risks of hypnotics (sleeping pills). This review includes new information on the growing USA overdose epidemic, eight new epidemiologic studies of hypnotics’ mortality not available for previous compilations, and new emphasis on risks of short-term hypnotic prescription. The most important risks of hypnotics include excess mortality, especially overdose deaths, quiet deaths at night, infections, cancer, depression and suicide, automobile crashes, falls, and other accidents, and hypnotic-withdrawal insomnia. The short-term use of one-two prescriptions is associated with greater risk per dose than long-term use. Hypnotics are usually prescribed without approved indication, most often with specific contraindications, but even when indicated, there is little or no benefit. The recommended doses objectively increase sleep little if at all, daytime performance is often made worse, not better, and the lack of general health benefits is commonly misrepresented in advertising. Treatments such as the cognitive behavioral treatment of insomnia and bright light treatment of circadian rhythm disorders might offer safer and more effective alternative approaches to insomnia.

    Yunjuan Gu

    Full Text Available AIM: The aim was to investigate the association between human insulin and cancer incidence and mortality in Chinese patients with type 2 diabetes. METHODS: We recruited 8,774 insulin-naïve diabetes patients from the Shanghai Diabetes Registry (SDR. The follow-up rate was 85.4%. All subjects were divided into the insulin use cohort (n = 3,639 and the non-insulin use cohort (n = 5,135. The primary outcome was the first diagnosis of any cancer. The secondary outcome was all-cause mortality. Cox proportional hazards model was used to estimate the relative risk (RR of cancer and mortality. RESULTS: We observed 98 cancer events in the insulin use cohort and 170 in the non-insulin use cohort. Cancer incidence rates were 78.6 and 74.3 per 10,000 patients per year in the insulin users and the non-insulin users, respectively. No significant difference in cancer risk was observed between the two cohorts (adjusted RR = 1.20, 95% CI 0.89-1.62, P = 0.228. Regarding site-specific cancers, only the risk of liver cancer was significantly higher in the insulin users compared to that in the non-insulin users (adjusted RR = 2.84, 95% CI 1.12-7.17, P = 0.028. The risks of overall mortality (adjusted RR = 1.89, 95% CI 1.47-2.43, P<0.0001 and death from cancer (adjusted RR = 2.16, 95% CI 1.39-3.35, P = 0.001 were all significantly higher in the insulin users than in the non-insulin users. CONCLUSION: There was no excess risk of overall cancer in patients with type 2 diabetes who were treated with human insulin. However, a significantly higher risk of liver cancer was found in these patients. Moreover, insulin users showed higher risks of overall and cancer mortality. Considering that individuals treated with insulin were more likely to be advanced diabetic patients, caution should be used in interpreting these results.

  20. Beyond breast cancer: mammographic features and mortality risk in a population of healthy women.

    Directory of Open Access Journals (Sweden)

    Rachel A Murphy

    Full Text Available BACKGROUND: Breast fibroglandular (dense tissue is a risk factor for breast cancer. Beyond breast cancer, little is known regarding the prognostic significance of mammographic features. METHODS: We evaluated relationships between nondense (fatty breast area and dense area with all-cause mortality in 4,245 initially healthy women from the Breast Cancer Detection Demonstration Project; 1,361 died during a mean follow-up of 28.2 years. Dense area and total breast area were assessed using planimeter measurements from screening mammograms. Percent density reflects dense area relative to breast area and nondense area was calculated as the difference between total breast area and dense area. Hazard ratios (HRs and 95% confidence intervals (CIs were estimated by Cox proportional hazards regression. RESULTS: In age-adjusted models, greater nondense and total breast area were associated with increased risk of death (HR 1.17, 95% CI 1.10-1.24 and HR 1.13, 95% CI 1.06-1.19, per SD difference while greater dense area and percent density were associated with lower risk of death (HR 0.91, 95% CI 0.86-0.95 and HR 0.87, 95% CI 0.83-0.92, per SD difference. Associations were not attenuated with adjustment for race, education, mammogram type (x-ray or xerogram, smoking status, diabetes and heart disease. With additional adjustment for body mass index, associations were diminished for all features but remained statistically significant for dense area (HR 0.94, 95% CI 0.89-0.99, per SD difference and percent density (HR 0.93, 95% CI 0.87-0.98, per SD difference. CONCLUSIONS: These data indicate that dense area and percent density may relate to survival in healthy women and suggest the potential utility of mammograms beyond prediction of breast cancer risk.
