European cancer mortality predictions for the year 2016 with focus on leukemias.

BACKGROUND: Current cancer mortality statistics are important for public health decision making and resource allocation. Age standardized rates and numbers of deaths are predicted for 2016 in the European Union. PATIENTS AND METHODS: Population and death certification data for stomach, colorectum, pancreas, lung, breast, uterus, prostate, leukemia and total cancers were obtained from the World Health Organisation database and Eurostat. Figures were derived for the EU, France, Germany, Italy, Poland, Spain and the UK. Projected numbers of deaths by age group were obtained for 2016 by linear regression on estimated numbers of deaths over the most recent time period identified by a joinpoint regression model. RESULTS: Projected total cancer mortality trends for 2016 in the EU are favourable in both sexes with rates of 133.5/100,000 men and 85.2/100,000 women (8% and 3% falls since 2011, due to population ageing) corresponding to 753,600 and 605,900 deaths in men and women for a total number of 1,359,500 projected cancer deaths (+3% compared to 2011). In men lung, colorectal and prostate cancer fell 11%, 5% and 8% since 2011. Breast and colorectal cancer trends in women are favourable (8% and 7% falls, respectively), but lung and Pancreatic cancer rates rose 5% and 4% since 2011 reaching rates of 14.4 and 5.6/100,000 women. Leukemia shows favourable projected mortality for both sexes and all age groups with stronger falls in the younger age groups, rates are 4.0/100,000 men and 2.5/100,000 women, with respectively falls of 14% and 12%. CONCLUSION: The 2016 predictions for EU cancer mortality confirm the favourable trends in rates particularly for men. Lung cancer is likely to remain the leading site for female cancer rates. Continuing falls in mortality, larger in children and young adults, are predicted in leukemia, essentially due to advancements in management and therapy, and their subsequent adoption across Europe.

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

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.

Sex and socioeconomic inequalities of lung cancer mortality in Barcelona, Spain and Sao Paulo, Brazil

The objective of this paper was to assess sex and socioeconomic inequalities in lung cancer mortality in two major cities of Europe and South America. Official information on mortality and population allowed the estimation of sex- and age-specific death rates for Barcelona, Spain and Sao Paulo, Brazil (1995-2003). Mortality trends and levels were independently assessed for each city and subsequently compared. Rate ratios assessed by Poisson regression analysis addressed hypotheses of association between the outcome and socioeconomic covariates (human development index, unemployment and schooling) at the inner-city area level. Barcelona had a higher mortality in men (76.9/100000 inhabitants) than Sao Paulo (38.2/100 000 inhabitants); although rates were decreasing for the former (-2%/year) and levelled-off for the [after. Mortality in women ranked similarly (9.1 for Barcelona, 11.5 for Sao Paulo); with an increasing trend for women aged 35-64 years (+ 7.7%/year in Barcelona and + 2.4%/year in Sao Paulo). The socioeconomic gradient of mortality in men was negative for Barcelona and positive for Sao Paulo; for women, the socioeconomic gradient was positive in both cities. Negative gradients indicate that deprived areas suffer a higher burden of disease; positive gradients suggest that prosmoking lifestyles may have been more prevalent in more affluent areas during the last decades. Sex and socioeconomic inequalities of lung cancer mortality reinforce the hypothesis that the epidemiologic profile of cancer can be improved by an expanded access to existing technology of healthcare and prevention. The continuous monitoring of inequalities in health may contribute to the concurrent promotion of well-being and social justice.

Oral cancer mortality trends in Brazilian geographical regions from 1996-2001

The purpose of this study was to analyse the oral cancer mortality trends in Brazil by geographic region, age and sex, from 1996 to 2001. The Brazilian Ministry of Health database DATASUS and the Brazilian Institute of Geography and Statistics were used as the source of data. Oral cancer mortality rates per 100,000 population were estimated. Statistical analyses comprised estimates of oral cancer mortality rates, grouped according to the study variables, in 1996, 1997, 1998, 1999, 2000 and 2001; also, the three-year periods 1996-1998 and 1999-2001 were analysed, allowing the oral cancer mortality trends between these two periods to be calculated. For comparison, in each geographical region, the ratio between two death rates (related to period or sex) was calculated. In the period 1996-2001, a total of 25,972 deaths due to oral cancer were reported, giving a mortality rate of 2.67. The rates for the periods 1996-1998 and 1999-2001 were 2.53 and 2.73, respectively, showing a slight increase in the rate. There was a predominance of oral cancer in males with a male/female ratio of approximately 4. All regions exhibited an increase in mortality rates, with the exception of the Southeast region. From 1996 to 2001, the average mortality rates were 3.55 and 3.58 for the Southeast and South regions, and 1.94, 1.41, and 0.86 for the Mid-West, Northeast, and North regions, respectively. Over the age of 40, oral cancer mortality rates were seen to increase rapidly with age. Oral cancer mortality increased in all regions, except in the Southeast, and was considerably higher among males and older individuals.

Disparities in female breast cancer mortality rates in Brazil between 1980 and 2009

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.

Trends in socioeconomic inequalities in cancer mortality in Barcelona: 1992–2003

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.

Cancer, a disease of aging (part 2) - risk factors for older adult cancer mortality in Switzerland 1991-2008

Cancer is disease of aging that disproportionately affects older adults and often results in considerable public health consequences. This study evaluated gender-age-specific cancer mortality risk factors in older adults in Switzerland with attention to the most common types of cancer.

Reduced estimated GFR and cancer mortality.

BACKGROUND Chronic kidney disease is associated with an increased risk of cancer, but whether reduced kidney function also leads to increased cancer mortality is uncertain. The aim of our study was to assess the independent effects of reduced kidney function on the risk of cancer deaths. STUDY DESIGN Prospective population-based cohort study. SETTING & PARTICIPANTS Participants of the Blue Mountains Eye Study (n=4,077; aged 49-97 years). PREDICTOR Estimated glomerular filtration rate (eGFR). OUTCOMES Overall and site-specific cancer mortality. RESULTS During a median follow-up of 12.8 (IQR, 8.6-15.8) years, 370 cancer deaths were observed in our study cohort. For every 10-mL/min/1.73 m(2) reduction in eGFR, there was an increase in cancer-specific mortality of 18% in the fully adjusted model (P<0.001). Compared with participants with eGFR ≥ 60 mL/min/1.73 m(2), the adjusted HR for cancer-specific mortality for those with eGFR<60 mL/min/1.73 m(2) was 1.27 (95% CI, 1.00-1.60; P=0.05). This excess cancer mortality varied with site, with the greatest risk for breast and urinary tract cancer deaths (adjusted HRs of 1.99 [95% CI, 1.05-3.85; P=0.01] and 2.54 [95% CI, 1.02-6.44; P=0.04], respectively). LIMITATIONS Residual confounding, such as from unmeasured socioeconomic factors and the potential effects of erythropoiesis-stimulating agents on cancer deaths, may have occurred. CONCLUSIONS eGFR<60 mL/min/1.73m(2) appears to be a significant risk factor for death from cancer. These effects appear to be site specific, with breast and urinary tract cancers incurring the greatest risk of death among those with reduced kidney function.
