Projeções de mortalidade por câncer de próstata no Brasil: um estudo de base populacional

Proyecciones de mortalidad por cáncer de próstata en Brasil: un estudio de base poblacional

Abstracts

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.

Introduction

Prostate cancer is considered globally to be the most prevalent and the sixth most mortal type of cancer in men. In Brazil, prostate cancer is the most common type of cancer in men and, in terms of the number of deaths, occupies second position, after lung cancer. The incidence rate is approximately 50 per 100,000 inhabitants, with more than 40,000 cases diagnosed annually. 14,500 deaths by prostate cancer are registered every year in Brazil, with rates of 16 deaths per 100,000 inhabitants per year, slightly fewer than lung cancer 1Ferlay J, Shin HR, Bray F, Forman D, Mathers C, Parkin DM. Globocan 2008: cancer incidence and mortality worldwide. Lyon: International Agency for Research on Cancer; 2010. (IARC Cancer Base, 10)..

It has been observed that prostate cancer mortality rates have not increased at the same rate as incidence rates, probably due to improvements in treatment associated with diagnosis measures 2Bernal M, Romero FJ, Souza DL, Gomez-Bernal FJ, Gomez-Bernal GJ. Estimation of the projections of incidence rates, prevalence and mortality due to prostate cancer in Aragon (Spain). Actas Urol Esp 2011; 35:470-4.. The prostate-specific antigen (PSA) test was responsible, principally after the 1980s, for causing increases in incidence and survival rates for prostate cancer, as a consequence of early diagnosis 3Neppl-Huber C, Zappa M, Coebergh JW, Rapiti E, Rachtan J, Holleczek B, et al. Changes in incidence, survival and mortality of prostate cancer in Europe and the United States in the PSA era: additional diagnoses and avoided deaths. Ann Oncol 2012; 23:1325-34.,4Marcos-Gragera R, Salmeron D, Izarzugaza I, Ardanaz E, Serda BC, Larranaga N, et al. Trends in prostate cancer survival in Spain: results from population-based cancer registries. Clin Transl Oncol 2012; 14:458-64.. However, the prevalence of PSA testing is relatively low in less developed countries, where Western influenced lifestyles have caused increases in prostate cancer rates 5Baade PD, Youlden DR, Krnjacki LJ. International epidemiology of prostate cancer: geographical distribution and secular trends. Mol Nutr Food Res 2009; 53:171-84.. In the case of Brazil, the adjusted mortality rates increased by approximately 70% from the early 1980s to the start of the 21st century 6Chatenoud L, Bertuccio P, Bosetti C, Levi F, Curado MP, Malvezzi M, et al. Trends in cancer mortality in Brazil, 1980-2004. Eur J Cancer Prev 2010; 19:79-86..

The International Agency for Research on Cancer (IARC) predicts that the number of deaths by prostate cancer in Brazil will almost double by the year 2025 1Ferlay J, Shin HR, Bray F, Forman D, Mathers C, Parkin DM. Globocan 2008: cancer incidence and mortality worldwide. Lyon: International Agency for Research on Cancer; 2010. (IARC Cancer Base, 10).. However, these projections are limited, as there are no age- or region- specific data available. The detailed study presented herein is very important in a country with a high proportion of inequalities and profound regional differences such as Brazil. Furthermore, trend analysis and cancer mortality projections are very useful for planned interventions such as screening programs and therapy advances, as well as to quantify the probable burden of cancer in the future.

The objective of this study is to carry out projections of prostate cancer mortality in Brazil and its regions until the year 2025, based on the trend analysis for the period 1996-2010.

Method

This is an ecological study for which the data were obtained from the Brazilian Ministry of Health web page (Departamento de Informática do SUS. Informações de Saúde. Estatísticas Vitais. http://www2.datasus.gov.br/DATASUS/index.php?area=0205, accessed on 02/Jul/2013) along with population data from 1996 to 2010. All deaths registered as prostate cancer (ICD-10 code: C61) were included in the analysis. The quality of death certificates is comparable to those of developed countries, and the proportion of ill-defined death causes is lower than 13% for the overall country and lower than 6% for the capital cities (Global Health Observatory Data Repository, World Health Organization. Demographic and Socioeconomic Statistics: Census and Civil Registration Coverage. Data by Country. http://apps.who.int/gho/data/node.main.121, accessed on 23/Apr/2014) 7Fonseca LA, Eluf-Neto J, Wunsch Filho V. Cancer mortality trends in Brazilian state capitals, 1980-2004. Rev Assoc Med Bras (1992) 2010; 56:309-12..

Analyses of mortality and predictions were performed by calculating crude and adjusted rates, expressed per 100,000 persons per year. The adjusted mortality rates were calculated by the direct method using the world standard population as reference for Brazil and its five regions (North, Northeast, Central, Southeast, and South). Adjusted rates for each year were calculated to study trends using the Joinpoint Regression Program (National Cancer Institute, Bethesda, USA). Crude rates were calculated, as well as the confidence intervals for the adjusted rates, to a confidence level of 95%. The objective was to determine whether the estimated trends were statistically significant or not. Joinpoint analysis identifies the moment in which changes in trends occur and calculates the annual percentage change (APC) in each segment. The analysis starts with a minimum number of joinpoints and compares whether one or more are significant to the model 8Kim HJ, Fay MP, Feuer EJ, Midthune DN. Permutation tests for joinpoint regression with applications to cancer rates. Stat Med 2000; 19:335-51.. Birth-cohort analysis was carried out graphically and dividing data in five- year periods.

Predictions were made for the periods 2011-2015, 2016-2020 and 2021-2025, using the age-period-cohort model of the Nordpred program (Cancer Registry of Norway, Oslo, Norway), written in the statistical program R. Data were pooled into five-year blocks and the age group limit considered for analysis was the one with more than 10 cases in the combined periods. Predictions were made by geographical region and the pooled results will be referred to as total presented by age ranges (0-54, 55-74 and ≥ 75 years of age). As prostate cancer is more common in individuals over the age of 55, age groups were employed following Moller et al. 9Møller B, Fekjaer H, Hakulinen T, Tryggvadottir L, Storm HH, Talback M, et al. Prediction of cancer incidence in the Nordic countries up to the year 2020. Eur J Cancer Prev 2002; 11 Suppl 1:S1-96.. Changes in the annual number of cases of the last predicted period relating to the last observed period (2006-2010) were calculated by geographical region. The proportion of this change occurring in terms of risk or change in population (size and population structure) was also calculated. These two components can be different from zero and present a positive or negative direction. The calculation can be expressed as follows 9Møller B, Fekjaer H, Hakulinen T, Tryggvadottir L, Storm HH, Talback M, et al. Prediction of cancer incidence in the Nordic countries up to the year 2020. Eur J Cancer Prev 2002; 11 Suppl 1:S1-96.,1010 Møller B, Fekjaer H, Hakulinen T, Sigvaldason H, Storm HH, Talback M, et al. Prediction of cancer incidence in the Nordic countries: empirical comparison of different approaches. Stat Med 2003; 22:2751-66.:

Δ tot = Δ risk + Δ pop = (N fff – N off ) + (N off – N ooo )

where: Δ tot = total change, Δ risk = change in function of risk, Δ pop = change in function of population, Nooo = number of observed cases, Nfff = number of predicted cases and Noff = number of expected cases when increasing the mortality rates in the observed period.

The Brazilian and regional population used in the projections were obtained from the website of the Brazilian Institute for Statistics and Geography (IBGE) 1111 Instituto Brasileiro de Geografia e Estatística.

Results

In the period 1996-2010, 139,349 deaths were registered in the Brazilian mortality database as being from prostate cancer. The Joinpoint analysis shows an initial increase in mortality rates, followed by a stable plateau after the year 2006. The same trend is found by region, with an exception for the North region, where significant increases were verified for the entire period. In the remaining regions, the initial increase occurred until the years 2005 and 2006, followed by a decrease in rates. However, the APC were not statistically significant in the second segment (Table 1).

Trend analysis for mortality by birth cohort shows an increment in rates for individuals in the age groups of 75-79 and 80-84 years of age, with a change in trends and stability for younger cohorts starting from 1933 (Figure 1).

Table 2 presents the total number of deaths and death by age group, along with rates that are adjusted to the world population, during the observed and projected periods, for Brazil and its geographic regions. For the projected period (2011-2025) an increase in the absolute number of deaths is predicted, reaching a total number of 236,086 cases. During the most recent period under observation (2006-2010), 59,647 deaths were registered, and 91,420 cases are expected for the last projected period (2021-2025). When comparing the most recent period with the last projected period, an increase of 53.3% is predicted in the number of deaths, with 60% of these being as a result of population changes, and a reduction of 6.8% is also expected in death risk by prostate cancer.

Figure 2 shows a comparison of prostate cancer mortality rates: observed adjusted versus projected for the five regions of Brazil. The predicted increase can be observed in the adjusted mortality rates for the North and Northeast regions, attributed both to increases in risk as well as to population changes. Decreases are predicted for the remaining regions (South, Southeast and Central) due to reductions in risk.

Discussion

From 1996 onwards, a significant increase in Brazilian prostate cancer mortality rates was observed, followed by a slight decrease in the period after 2006. The projections of this study indicate decreases in mortality rates from prostate cancer in Brazil, as well as in the South, Southeast and Central regions, until the year 2025. In contrast, an increase is predicted in the rates of less developed regions of the country, in the North and particularly in the Northeast region. Nevertheless, it must be mentioned that it is expected that the absolute number of deaths from prostate cancer increases in all regions due to the population aging process in Brazil. This increase in mortality is predicted to be smooth in the South and Southeast regions, as a consequence of the reduction in risk or increased effectiveness of early diagnosis, while for the North and Northeast regions the changes in risk and population may almost double the number of deaths by the year 2025.

When analyzing cancer projections two situations must be distinguished, which could influence the number of deaths: changes in death risk by cancer and changes in the exposed population itself. Population changes can occur due to population increases and structural changes 1212 Bray F, Møller B. Predicting the future burden of cancer. Nat Rev Cancer 2006; 6:63-74.,1313 Souza DL, Curado MP, Bernal MM, Jerez-Roig J, Boffetta P. Mortality trends and prediction of HPV-related cancers in Brazil. Eur J Cancer Prev 2013; 22:380-7.. In Brazil, the global phenomenon of population aging is picking up speed, due to the quite steep decline in fecundity rates, decreases in mortality, and increases in life expectancy 1313 Souza DL, Curado MP, Bernal MM, Jerez-Roig J, Boffetta P. Mortality trends and prediction of HPV-related cancers in Brazil. Eur J Cancer Prev 2013; 22:380-7.. The number of individuals over the age of 60 is expected to increase by approximately 60% from the period 2006-2010 to 2021-2025 1111 Instituto Brasileiro de Geografia e Estatística. Projeção da população do Brasil por sexo e idade: 1980-2050. Revisão 2008. v. 24. Rio de Janeiro: Instituto Brasileiro de Geografia e Estatística; 2008.. This trend will particularly affect the case of prostate cancer, as age is known to be one of the main risk factors associated with incidence and mortality from this disease 1414 Stasiewicz D, Staroslawska E, Brzozowska A, Mocarska A, Losicki M, Szumilo J, et al. Epidemiology and risk factors of the prostate cancer. Pol Merkur Lekarski 2012; 33:163-7.,1515 Ferris-i-Tortajada J, Garcia-i-Castell J, Berbel-Tornero O, Ortega-Garcia JA. Constitutional risk factors in prostate cancer. Actas Urol Esp 2011; 5:282-8..

Regarding cancer mortality rates, there are three factors that could exert an influence: changes in risk factors for the development of the disease, screening programs and advances in treatment 1616 Bezerra-de-Souza DL, Bernal MM, Gomez FJ, Gomez GJ. Predictions and estimations of colorectal cancer mortality, prevalence and incidence in Aragon, Spain, for the period 1998-2022. Rev Esp Enferm Dig 2012; 104:518-23.. Currently it is known that non-modifiable risk factors, such as family-genetic factors and especially age, play an important role in the development of prostate cancer. However, these factors do not affect the analysis presented herein because this study analyzed age-adjusted rates and at a collective level, where there is a low influence of family-genetic factors. Regarding modifiable risk factors, such as obesity and the consumption of tobacco and alcohol, which have already been established for other types of cancer, the association remains little known for prostate cancer 1515 Ferris-i-Tortajada J, Garcia-i-Castell J, Berbel-Tornero O, Ortega-Garcia JA. Constitutional risk factors in prostate cancer. Actas Urol Esp 2011; 5:282-8.. For this reason, it is not possible to explain the influence of these factors in the regional differences in mortality rates encountered herein.

An explanation for the change from an initial increase to the stable plateau observed in this study could be a result of the improvements in screening programs and therapeutic measures in the more developed regions of Brazil. Prostate cancer screening has not been systematically applied in Brazil, and there is an inequality in the availability of diagnostic tests with regard to socio-demographic and socioeconomic levels. In this way, the difficulty of accessing diagnosis and treatment services for individuals in conditions of poverty could explain the higher prostate cancer mortality rates observed in the low stratum 1717 Belon AP, Barros MB, Marin-Leon L. Mortality among adults: gender and socioeconomic differences in a Brazilian city. BMC Public Health 2012; 12:39.. This difficulty in accessing diagnosis services seems to occur with a greater frequency in the North and Northeast regions, where the projections of this study reveal increasing mortality rates. Therefore some studies show that prostate cancer tracking is less prevalent in men under the age of 70, with less years of schooling, and of low-income 1717 Belon AP, Barros MB, Marin-Leon L. Mortality among adults: gender and socioeconomic differences in a Brazilian city. BMC Public Health 2012; 12:39.,1818 Amorim VM, Barros MB, Cesar CL, Goldbaum M, Carandina L, Alves MC. Fatores associados à realização dos exames de rastreamento para o câncer de próstata: um estudo de base populacional. Cad Saúde Pública 2011; 27:347-56.. An ecological study carried out in Brazil has found that approximately 57% of the individuals with a higher education level related diagnostic practices such as digital rectal exam or PSA, while for individuals with less years of schooling the percentage was only 35% 1717 Belon AP, Barros MB, Marin-Leon L. Mortality among adults: gender and socioeconomic differences in a Brazilian city. BMC Public Health 2012; 12:39..

A pronounced inequity between the regions of Brazil remains regarding access to prostate cancer treatment. The different mortality trends encountered herein can be partially attributed to that fact that therapeutic services are much more limited in less developed regions of Brazil (the North and Northeast). In municipalities in the interior of these areas, Silva et al. 1919 Silva GA, Gamarra CJ, Girianelli VR, Valente JG. Cancer mortality trends in Brazilian state capitals and other municipalities between 1980 and 2006. Rev Saúde Pública 2011; 45:1009-18. have found increases in cancer rates twice as high as those registered in capital cities of the country. In these regions, low-income individuals that use the public health system occasionally suffer as a result of late diagnoses, precariousness of services and tardiness in beginning treatment, which compromises prognostics. In addition, a much higher offer of chemotherapy and radiotherapy services is concentrated in the South and Southeast regions, where there is a higher proportion of individuals who can afford private health plans 1818 Amorim VM, Barros MB, Cesar CL, Goldbaum M, Carandina L, Alves MC. Fatores associados à realização dos exames de rastreamento para o câncer de próstata: um estudo de base populacional.

Rev Saúde Pública 2011; 45:1009-18..

The evolution observed in the rates of this study for the more developed regions of Brazil is similar to that found in the majority of European countries and the USA. In these countries, mortality rates have declined during the last two decades, probably due to early diagnoses facilitated by the PSA testing and improvements in prostate cancer treatment 4Marcos-Gragera R, Salmeron D, Izarzugaza I, Ardanaz E, Serda BC, Larranaga N, et al. Trends in prostate cancer survival in Spain: results from population-based cancer registries. Clin Transl Oncol 2012; 14:458-64.,5Baade PD, Youlden DR, Krnjacki LJ. International epidemiology of prostate cancer: geographical distribution and secular trends. Mol Nutr Food Res 2009; 53:171-84.,2020 Bray F, Lortet-Tieulent J, Ferlay J, Forman D, Auvinen A. Prostate cancer incidence and mortality trends in 37 European countries: an overview. Eur J Cancer 2010; 46:3040-52.. Such a trend has also been observed in other South American countries, as is the case of Chile and Argentina. Nevertheless, it is worth highlighting that in these countries, the adjusted rates are higher than the Brazilian rates, with changes occurring earlier, at the end of the 1990s (International Agency for Research on Cancer; World Health Organization. Cancer Mortality Database. http://www-dep.iarc.fr/whodb/whodb.htm, accessed on 30/Jul/2013) 2121 Vives A, Valdivia G, Marshall G.

Cad Saúde Pública 2011; 27:123-30..

As a limitation of this study, the period for which the projections apply – just 15 years – is short. Regarding the national registry of deaths by cancer in Brazil, it must be mentioned that in the past there were issues with data reliability, particularly in the North and Northeast regions, but improvements have been made since the 2000s 6Chatenoud L, Bertuccio P, Bosetti C, Levi F, Curado MP, Malvezzi M, et al. Trends in cancer mortality in Brazil, 1980-2004. Eur J Cancer Prev 2010; 19:79-86.. Cancer projections must be considered with caution, as the actual diagnosis and treatment conditions might change in the future, and consequently modify the mortality trends. However, the methods currently used have certified validity and some authors point to small differences of between 10 and 20% in estimations 2Bernal M, Romero FJ, Souza DL, Gomez-Bernal FJ, Gomez-Bernal GJ. Estimation of the projections of incidence rates, prevalence and mortality due to prostate cancer in Aragon (Spain). Actas Urol Esp 2011; 35:470-4..

In conclusion, an initial increase in prostate cancer mortality rates was herein demonstrated, followed by a slight decrease in rates that is predicted to take place until the year 2025 in the entire country. However, in the North and Northeast regions increases in mortality are expected, attributed to changes in risk and the aging of the population. The results of the projections presented herein clearly show the inequities present in prostate cancer mortality rates per geographic region, which must be considered for the development of public policies and for the planning of health services.
