RESUMEN
OBJECTIVE: To review the pathological diagnosis of possible cases and/or hidden cases of malignant mesothelioma (MM) between 2000 and 2012 using the Hospital-Based Cancer Registry database in the state of São Paulo, Brazil. METHODS: Possible cases were retrieved by assessing the database. Inclusion criteria were being older than 30 years of age and having ICD-O-3 topography and morphology codes related to MM. A board of expert pathologists reviewed the pathology reports and requested paraffin blocks in cases that demanded revision. After staining with calretinin, D2-40, WT-1 (as positive MM markers) and Ber-EP4 and MOC31 (as negative MM markers), cases were divided and studied independently by a pair of pathologists to confirm or discard the diagnosis of MM. RESULTS: Our sample comprised 482 cases from 25 hospitals, and 130 needed further histological revision. We received 73 paraffin blocks with adequate material. After board analysis, there were 9 cases with a definitive diagnosis of MM, improving the diagnostic rate in 12%. Two cases of previously diagnosed MM were discarded by review. CONCLUSIONS: Our results confirm that part of MM underdiagnosis and underreporting in Brazil is due to incomplete or mistaken pathological diagnosis.

RESUMEN
BACKGROUND: Pancreatic cancer mortality is greater in countries with a high Human Development Index (HDI). This study analyzed pancreatic cancer mortality rates trends, and their correlation with HDI in Brazil over 40 years. METHODS: Data on pancreatic cancer mortality in Brazil between 1979 and 2019 were obtained from the Mortality Information System (SIM). Age-standardized mortality rates (ASMR) and Annual Average Percent Change (AAPC) were calculated. Pearson's correlation test was applied to compare mortality rates and HDI for three periods: 1986-1995 was correlated with HDI of 1991, 1996-2005 with HDI of 2000, and 2006-2015 with HDI of 2010; and to the correlation of AAPC versus the percentage change in HDI from 1991 to 2010. RESULTS: A total of 209,425 deaths from pancreatic cancer were reported in Brazil, with an annual increase of 1.5% in men and 1.9% in women. There was an upward trend for mortality in most Brazilian states, with the highest trends observed in the North and Northeast states. A positive correlation between pancreatic mortality and HDI was observed over the three decades (r>0.80, P<0.05) and also between AAPC and HDI improvement by sex (r=0.75 for men and r=0.78 for women, P<0.05). CONCLUSION: There was an upward trend in pancreatic cancer mortality in Brazil for both sexes, but rates among women were higher. Mortality trends were higher in states with a higher percentage improvement in HDI, such as the North and Northeast states.

RESUMO Contexto A mortalidade por câncer de pâncreas é maior em países com alto Índice de Desenvolvimento Humano (IDH). Este estudo analisou as taxas e tendências de mortalidade por câncer de pâncreas e correlacionou-as com o IDH no Brasil no período de 40 anos. Métodos: Os dados sobre mortalidade por câncer de pâncreas no Brasil, entre 1979 e 2019, foram extraídos do Sistema de Informações sobre Mortalidade (SIM). As taxas de mortalidade padronizadas por idade e variação percentual média anual (AAPC) foram calculadas. O teste de correlação de Pearson foi aplicado para comparar as taxas de mortalidade e IDH em três períodos: 1986-1995 foi correlacionado com o IDH de 1991, 1996-2005 com IDH 2000 e 2006-2015 com IDH 2010; e a correlação da AAPC versus o percentual de variação do IDH de 1991 a 2010. Resultados: Foram notificados 209.425 óbitos por câncer de pâncreas no Brasil no período de 1979 a 2019, com aumento de 1,5% ao ano em homens e de 1,9% em mulheres. Houve tendência de aumento da mortalidade na maioria dos estados brasileiros, com maiores tendências nos estados das regiões Norte e Nordeste. Foi observada uma correlação positiva na mortalidade por câncer de pâncreas e o IDH ao longo de três décadas (r>0,80, P<0,05); também, entre o AAPC e o incremento do IHD entre 1991 e 2010 (r=0,75 para homens e r=0,78 para mulheres, P<0,05). Conclusão: Houve tendência crescente da mortalidade por câncer de pâncreas no Brasil, em ambos os sexos, porém maior entre as mulheres. As tendências de mortalidade foram maiores nos estados com maior percentual de incremento do IDH, como estados das regiões Norte e Nordeste.
RESUMEN
Introdução: O câncer de pâncreas é um tumor de alta letalidade, é o décimo segundo tipo mais comum e a sétima causa de morte, em ambos os sexos, no mundo. Estima-se que o câncer de pâncreas terá um aumento contínuo de incidência e mortalidade nos próximos 20 anos e isso causará um enorme ônus econômico para as populações em todo o mundo. Para o monitoramento e vigilância epidemiológica em câncer, pode-se apoiar em dados secundários como no Sistema de Informação em Mortalidade e dos registros de câncer (de base populacional e hospitalares) e estimativas a partir destes dados; por essa razão, investigou-se a epidemiologia do câncer de pâncreas na América Latina e no Brasil. Métodos: A tese compreende três manuscritos: (i) tendências de incidência, mortalidade e anos de vida ajustados por incapacidade (DALYs), bem como a fração de mortes por câncer de pâncreas atribuíveis a fatores de risco comportamentais e metabólicos em países da América Latina e Caribe (LAC) entre 1990 e 2019 (Global Burden Disease, 2019); (ii) mortalidade por câncer de pâncreas no Brasil e unidades da federação entre 1979 e 2019, dados do Sistema de Informação em Mortalidade (SIM); (iii) comparabilidade, validade, completude e pontualidade para cinco tumores gastrointestinais, câncer de esôfago, estômago, colorretal, fígado e pâncreas, em Registros de Câncer de Base Populacional (RCBPs) brasileiros. Resultados: Observou-se um aumento na incidência, mortalidade e DALYs para o câncer de pâncreas em ambos os sexos na maioria dos países da América Latina e Caribe; as maiores taxas de incidência e mortalidade foram observadas no Uruguai e as menores no Haiti. Redução na fração de mortes atribuíveis ao tabagismo entre 1990 e 2019, para ambos os sexos nos países da LAC; entretanto, aumento dentre os fatores metabólicos. No Brasil, entre 1979 e 2019, foram notificados um total de 209.425 óbitos por câncer de pâncreas, com tendência de aumento de 1,5% ao ano em homens e 1,9% em mulheres. Houve tendência de aumento da mortalidade na maioria dos estados brasileiros, com maiores tendências nas regiões Norte e Nordeste, e correlação positiva entre o índice de desenvolvimento humano e a tendência de aumento da mortalidade por câncer de pâncreas. Dentre os dezesseis RCBPs brasileiros estudados, todos atenderam aos critérios de comparabilidade, porém metade apresentou índices abaixo do esperado para validade e completude para tumores de fígado e pâncreas. Para pontualidade, os dezesseis registros apresentaram mais de 48 meses de atraso na divulgação dos dados em relação ao ano calendário de 2023. Considerações finais: O câncer de pâncreas representa um desafio para a saúde pública nos países da América Latina e no Brasil, diante do desafio na redução da incidência e da mortalidade, assim como na vigilância epidemiológica em câncer através dos RCBPs brasileiros que necessitam de suporte para continuidade do monitoramento da incidência do câncer.
Introduction: Pancreatic cancer is a tumor of high lethality, is the twelfth most common type and the seventh cause of death, in both sexes, in the world. It is estimated that pancreatic cancer will have a continuous increase in incidence and mortality over the next 20 years and this will cause a huge economic burden for populations around the world. For epidemiological monitoring and surveillance in cancer, it is possible to use on secondary data such as the Mortality Information System and cancer registries (population-based and hospital) and estimates from these data, for this reason the epidemiology of pancreatic cancer in Latin America and Brazil was investigated. Methods: The thesis comprises three manuscripts: (i) trends in incidence, mortality and disability-adjusted life years (DALYs) as well as the fraction of pancreatic cancer deaths attributable to behavioral and metabolic risk factors in Latin American and Caribbean (LAC) countries between 1990 and 2019 (Global Burden Disease, GBD 2019); (ii) mortality from pancreatic cancer in Brazil and federal units between 1979 and 2019, data from the Mortality Information System (SIM); (iii) comparability, validity, completeness and timeless for five gastrointestinal tumors, esophageal, stomach, colorectal, liver and pancreatic cancers, in the Brazilian Population-Based Cancer Registries (PBCRs). Results: An increase in the incidence, mortality and DALYs of pancreatic cancer was observed in most countries in Latin America and the Caribbean, the highest incidence and mortality rates were observed in Uruguay and the lowest in Haiti. The fraction of pancreatic cancer deaths attributable to smoking reduced between 1990 and 2019 for both sexes in LAC countries, however, it increased for metabolic risk factors. In Brazil, between 1979 and 2019, a total of 209,425 deaths from pancreatic cancer were reported, with a trend of increase of 1.5% per year in men and 1.9% in women. There was an increase in mortality in most Brazilian states, higher in the North and Northeast regions with a positive correlation between the improvement of the human development index and the trend of increased mortality from pancreatic cancer. Among the sixteen Brazilian PBCRs studied, all agreement the criteria of comparability, but half have lower than expected indices for validity and completeness for liver and pancreatic tumors, and as for timeless the sixteen records are more than 48 months late in the release of data in relation to the calendar year 2023. Conclusions: Pancreatic cancer represents a challenge for public health in LAC and Brazil, given the challenge in reducing incidence and mortality, as well as in epidemiological surveillance in cancer through Brazilian PBCRs to ensure the activity and stability for continued monitoring of cancer incidence.

OBJECTIVE: To estimate the degree of agreement and validity of diagnoses of asbestos-related malignant neoplasms registered in the Hospital Information System of the Brazilian Unified Health System (SIH/SUS), in comparison to the Hospital Cancer Registries of the State of São Paulo (HCR/SP). METHODS: Deaths with records of malignant neoplasms associated with asbestos were identified and extracted from SIH/SUS between 2007 and 2014. Deaths in cases registered in the HCR/SP were extracted for the same period. The databases were linked using software Link Plus. A single ICD-10-coded diagnosis selected from each system was analyzed. The proportion of agreement, and the sensitivity, specificity and predictive values were estimated. RESULTS: 19,458 pairs were found with records in both bases. The proportion of agreement was high, ranging from 92.4% for the unknown primary site, to 99.7% for cancer of the pleura. The Kappa Index ranged from 0.05 (95%CI 0.04 - 0.07) for cancer of the pleura to 0.85 (95%CI 0.84 - 0.87) for lung cancer. Sensitivity varied from 0.08 (95%CI 0.01 - 0.25) for cancer of the pleura, to 0.90 (95%CI 0.90 - 0.91) for lung cancer. CONCLUSION: Diagnosis of asbestos-related malignancies reached higher levels of agreement and validity when common. Rare diagnoses showed low accuracy in SIH/SUS.
OBJETIVO: Estimar o grau de concordância e validade dos diagnósticos de neoplasias malignas relacionadas à exposição ao asbesto registrados no Sistema de Informação Hospitalar do Sistema Único de Saúde (SIH/SUS), em comparação aos Registros Hospitalares de Câncer do Estado de São Paulo (RHC/SP). MÉTODOS: Óbitos com registros de neoplasias malignas associadas ao asbesto foram identificados e extraídos do SIH/SUS entre 2007 e 2014. Óbitos nos casos de câncer registrados na base do RHC/SP foram extraídos para o mesmo período. Essas bases foram unidas pelos mesmos indivíduos empregando-se o software Link Plus. Um único diagnóstico codificado pela CID-O3 ou CID-10 selecionado de cada sistema foi analisado. A proporção de concordância e a sensibilidade, especificidade e valores preditivos foram estimados. RESULTADOS: Encontraram-se 19.458 pares com registros nas duas bases. A proporção de concordância foi elevada, variando de 92,4% para a localização primária desconhecida a 99,7% para o câncer de pleura. O índice Kappa variou de 0,05 (IC95% 0,04 - 0,07) para o câncer de pleura a 0,85 (IC95% 0,84 - 0,87) para o câncer de pulmão. A menor sensibilidade foi de 0,08 (IC95% 0,01 - 0,25), para o câncer de pleura, e a maior de 0,90 (IC95% 0,90 - 0,91), para o câncer de pulmão. CONCLUSÃO: Diagnósticos de neoplasias malignas associadas ao asbesto alcançaram maiores níveis de concordância e validade quando comuns. Os diagnósticos mais raros apresentaram baixa acurácia no SIH/SUS.

OBJECTIVE: To develop a linkage algorithm to match anonymous death records of cancer of the larynx (ICD-10 C32X), retrieved from the Mortality Information System (SIM) and the Hospital Information System of the Brazilian Unified National Health System (SIH-SUS) in Brazil. METHODOLOGY: Death records containing ICD-10 C32X codes were retrieved from SIM and SIH-SUS, limited to individuals aged 30 years and over, between 2002 and 2012, in the state of São Paulo. The databases were linked using a unique key identifier developed with sociodemographic data shared by both systems. Linkage performance was ascertained by applying the same procedure to similar non-anonymous databases. True pairs were those having the same identification variables. RESULTS: A total of 14,311 eligible death records were found. Most records, 10,674 (74.6%), were exclusive to SIM. Only 1,853 (12.9%) deaths were registered in both systems, representing true pairs. A total of 1,784 (12.5%) cases of laryngeal cancer in the SIH-SUS database were tracked in SIM with different causes of death. The linkage failed to match 167 (9.4%) records due to inconsistencies in the key identifier. CONCLUSION: The authors found that linking anonymous data from mortality and hospital records is a feasible measure to track missing records and may improve cancer statistics.

RESUMO: Objetivo: Desenvolver um algoritmo de vinculação de registros para parear registros de óbito por câncer de laringe (CID-10 C32X), recuperados do Sistema de Informação de Mortalidade (SIM) e do Sistema de Informações Hospitalares do Sistema Único de Saúde (SIH-SUS) do Brasil. Métodos: Foram filtrados registros de óbitos contendo códigos CID-10 C32X do SIM e do SIH-SUS, de indivíduos de mais de 30 anos, entre 2002 e 2012, no Estado de São Paulo. As bases de dados foram vinculadas por meio de um identificador único e de variáveis sociodemográficas comuns a ambos os sistemas. O desempenho da vinculação de dados foi aferido aplicando-se o mesmo procedimento em bancos de dados nominais. Os pares verdadeiros apresentavam os mesmos valores nas variáveis de identificação. Resultados: Ao todo, 14.311 registros elegíveis de óbito foram encontrados. A maioria dos registros, 10.674 (74.6%), era exclusiva do SIM. Apenas 1.853 (12.9%) óbitos foram registrados em ambos os sistemas, representando pares verdadeiros. Um total de 1.784 (12.5%) casos de câncer de laringe presentes no SIH-SUS constavam com diferentes causas de óbito no SIM. Houve falha na vinculação em 167 (9.4%) registros, devido a inconsistências na chave de identificação. Conclusão: Constatou-se que a vinculação de dados anônimos de registros hospitalares e registros de óbito é viável e pode auxiliar na melhoria de estatísticas de câncer.

BACKGROUND: Hospital-based studies recently have shown increases in colorectal cancer survival, and better survival for women, young people, and patients diagnosed at an early disease stage. OBJECTIVE: To describe the overall survival and analyze the prognostic factors of patients treated for colorectal cancer at an oncology center. METHODS: The analysis included patients diagnosed with colon and rectal adenocarcinoma between 2000 and 2013 and identified in the Hospital Cancer Registry at A.C.Camargo Cancer Center. Overall 5-year survival was estimated using the Kaplan-Meier method, and prognostic factors were evaluated in a Cox regression model. Hazard ratios (HR) are reported with 95% confidence intervals (CI). RESULTS: Of 2,279 colorectal cancer cases analyzed, 58.4% were in the colon. The 5-year overall survival rate for colorectal cancer patients was 63.5% (65.6% and 60.6% for colonic and rectal malignancies, respectively). The risk of death was elevated for patients in the 50-74-year (HR=1.24, 95%CI =1.02-1.51) and ≥75-year (HR=3.02, 95%CI =2.42-3.78) age groups, for patients with rectal cancer (HR=1.37, 95%CI =1.11-1.69) and for those whose treatment was started >60 days after diagnosis (HR=1.22, 95%CI =1.04-1.43). The risk decreased for patients diagnosed in recent time periods (2005-2009 HR=0.76, 95%CI =0.63-0.91; 2010-2013 HR=0.69, 95%CI =0.57-0.83). CONCLUSION: Better survival of patients with colorectal cancer improves with early stage and started treatment within 60 days of diagnosis. Age over 70 years old was an independent factor predictive of a poor prognosis. The overall survival increased to all patients treated in the period 2000-2004 to 2010-2013.

RESUMO CONTEXTO: Estudos hospitalares recentes têm demonstrado aumento da sobrevida do câncer colorretal e melhor sobrevida para mulheres, jovens e pacientes diagnosticados em estágio precoce da doença. OBJETIVO: Descrever a sobrevida global e analisar os fatores prognósticos de pacientes tratados para câncer colorretal em um centro de oncologia. MÉTODOS: Foram incluídos pacientes com diagnóstico de adenocarcinoma de cólon e reto entre 2000 e 2013, identificados no Registro Hospitalar de Câncer do A.C.Camargo Cancer Center. A sobrevida global aos 5 anos foi estimada pelo método de Kaplan-Meier e os fatores prognósticos foram avaliados pelo modelo de Cox. As razões de risco (HR) são relatadas com intervalos de confiança (IC) de 95%. RESULTADOS: Dos 2.279 casos de câncer colorretal analisados, 58,4% eram de cólon. A taxa de sobrevida global aos 5 anos para pacientes com câncer colorretal foi de 63,5% (65,6% e 60,6% para câncer de cólon e retal, respectivamente). O risco de óbito foi elevado para pacientes na faixa etária de 50-74 anos (HR=1,24; IC95% =1,02-1,51) e ≥75 anos (HR=3,02; IC95% =2,42-3,78), para pacientes com câncer retal (HR=1,37; IC95% =1,11-1,69) e para aqueles cujo tratamento foi iniciado >60 dias após o diagnóstico (HR=1,22; IC95% =1,04-1,43). O risco diminuiu para pacientes diagnosticados em períodos recentes (2005-2009 HR=0,76; IC95% =0,63-0,91; 2010-2013 HR=0,69; IC95% =0,57-0,83). CONCLUSÃO: A sobrevida dos pacientes com câncer colorretal é maior naqueles em estágio inicial e com início do tratamento antes dos 60 dias.. Idade acima de 70 anos foi fator independente preditivo de mau prognóstico. A sobrevida global aumentou para todos os pacientes tratados no período de 2000-2004 a 2010-2013.

OBJECTIVE: We aimed to estimate the overall survival (OS) and conditional survival (CS) in patients diagnosed with oral and oropharyngeal squamous cell carcinoma (SCC) and to determine their survival trends. METHODS: The study included all consecutive patients treated at the A.C. Camargo Cancer Center for oral or oropharyngeal SCC between 2001 and 2012. Data were obtained from the Hospital Cancer Registry. OS and CS were analyzed using the Kaplan-Meier method to evaluate the probability of survival with Cox predictor models. RESULTS: Data of 505 oral and 380 oropharyngeal SCC patients obtained in 2001-2006 and 2007-2012 were analyzed. Most of the oral SCC (59%) and oropharyngeal SCC (90%) patients had stages III-IV SCC. The 5-year OS for patients with oral SCC was 51.7%, with no significant difference between the first and second periods. The CS rates in 2007-2012 were 65% after the first year and 86% up to the fifth year. For oropharyngeal SCC, the 5-year OS rate was 45.0% in the first period. The survival rate increased to 49.1% from 2007 to 2012, with a reduction in the risk of death (HR=0.69;0.52-09.2). The CS estimates from 2007 to 2012 were 59% after the first year and 75% up to the fifth year. CONCLUSION: Survival across the two time periods remained stable for oral SCC but showed a significant increase for oropharyngeal SCC, possibly because of improvements in the patients' response to radiotherapy, such as intensity-modulated radiation therapy, and the use of more accurate diagnostic imaging approaches.

Background: Despite decreasing global incidence trends, gastric cancer is still among the five most incident cancers in the world and the third cancer-related cause of death. In Brazil, differences in incidence and mortality exist depending on the geographic region studied. Objective: To describe the incidence, mortality, trends and age-period-cohort of gastric cancer in three cities of Brazil (Sao Paulo, Belem and Fortaleza), in the period 1990-2012. Mortality for gastric cancer in Brazil overall and by region was described. Methods: 33,462 incident cases of gastric cancer were identified from the population-based cancer registries and 23,424 deaths from mortality information system in residents of the three cities and in Brazil were included in the study. Data for incident cases were extracted from the Population Based Cancer Registries from the National Cancer Institute (INCA). Mortality data on gastric cancer were extracted from Information Technology Department of Brazilian Public Health Care System/Health Ministry (DATASUS/MS). Mortality and incidence age standardized rates were calculated. For trends analysis the Joinpoint Regression and age-period-cohort model were applied. Results: Belem presented the highest incidence rates for gastric adenocarcinoma. Decreasing incidence trends were identified in Sao Paulo (-7.8% in men; -6.3% in women) and in Fortaleza (-1.2% in men). Increasing incidence trends were observed for women in Belem (1.8%) and Fortaleza (1.1%). In Belem (Amazon area), there was an increased risk for gastric cancer in women born after the 1960s. Overall in Brazil mortality for gastric cancer is decreasing. Mortality trends showed significant reduction, for both sexes, in the three Brazilian cities. Conclusion: Incidence of gastric cancer is increasing in women born in the sixties in Belem (Amazon region) and Fortaleza (Northeast region). In Brazil there was increase in mortality in Northeast region and decrease in others regions. More update data on incidence for Amazon and Northeast region is needed.

ABSTRACT Objective: To analyze mortality from idiopathic pulmonary fibrosis (IPF) in Brazil over the period 1979-2014. Methods: Microdata were extracted from the Brazilian National Ministry of Health Mortality Database. Only deaths for which the underlying cause was coded as International Classification of Diseases version 9 (ICD-9) 515 or 516.3 (until 1995) or as ICD version 10 (ICD-10) J84.1 (from 1996 onward) were included in our analysis. Standardized mortality rates were calculated for the 2010 Brazilian population. The annual trend in mortality rates was analyzed by joinpoint regression. We calculated risk ratios (RRs) by age group, time period of death, and gender, using a person-years denominator. Results: A total of 32,092 deaths were recorded in the study period. Standardized mortality rates trended upward, rising from 0.24/100,000 population in 1979 to 1.10/100,000 population in 2014. The annual upward trend in mortality rates had two inflection points, in 1992 and 2008, separating three distinct time segments with an annual growth of 2.2%, 6.8%, and 2.4%, respectively. The comparison of RRs for the age groups, using the 50- to 54-year age group as a reference, and for the study period, using 1979-1984 as a reference, were 16.14 (14.44-16.36) and 6.71 (6.34-7.12), respectively. Men compared with women had higher standardized mortality rates (per 100,000 person-years) in all age groups. Conclusion: Brazilian IPF mortality rates are lower than those of other countries, suggesting underdiagnosis or underreporting. The temporal trend is similar to those reported in the literature and is not explained solely by population aging.
RESUMO Objetivo: Analisar a mortalidade por fibrose pulmonar idiopática (FPI) no Brasil no período de 1979-2014. Métodos: Foram extraídos microdados do Sistema de Informações de Mortalidade do Ministério da Saúde cuja causa básica de óbito tenha sido codificada conforme a Classificação Internacional das Doenças, 9ª edição, códigos 515 ou 516.3 (até 1995), e 10ª versão, código J84.1 (a partir de 1996). Os coeficientes de mortalidade padronizados foram calculados para a população brasileira de 2010. A tendência anual da mortalidade foi analisada pelo método de regressão por pontos de inflexão. Foram calculadas as razões de risco (RR) por faixa etária, período analisado e gênero, utilizando-se como denominador pessoas-ano. Resultados: Foram registrados 32.092 óbitos no período estudado. O coeficiente de mortalidade padronizado mostrou-se ascendente, passando de 0,24/100.000 habitantes em 1979 para 1,10/100.000 em 2014. A tendência anual de crescimento identificou dois pontos de inflexão, em 1992 e 2008, gerando três retas com crescimento anual percentual de 2,2%, 6,8% e 2,4%, respectivamente. As RR (IC95%) por faixa etária, elegendo a faixa de 50-54 anos como referência, e por período estudado, elegendo o período de 1979-1984 como referência, foram de 16,14 (14,44-16,36) e de 6,71 (6,34-7,12), respectivamente. Homens, comparados a mulheres, apresentaram taxas de mortalidade padronizadas (por 100.000 pessoas-ano) superiores em todas as faixas etárias. Conclusões: Os coeficientes de mortalidade brasileiros por FPI são inferiores aos de outros países, podendo indicar subdiagnóstico ou subnotificação. A tendência temporal é semelhante à descrita na literatura e não é justificada apenas pelo envelhecimento populacional.

ABSTRACT: Objective: To describe the incidence and mortality rates from colon and rectal cancer in Midwestern Brazil. Methods: Data for the incidence rates were obtained from the Population-Based Cancer Registry (PBCR) according to the available period. Mortality data were obtained from the Mortality Information System (SIM) for the period between 1996 and 2008. Incidence and mortality rates were calculated by gender and age groups. Mortality trends were analyzed by the Joinpoint software. The age-period-cohort effects were calculated by the R software. Results: The incidence rates for colon cancer vary from 4.49 to 23.19/100,000, while mortality rates vary from 2.85 to 14.54/100,000. For rectal cancer, the incidence rates range from 1.25 to 11.18/100,000 and mortality rates range between 0.30 and 7.90/100,000. Colon cancer mortality trends showed an increase among males in Cuiabá, Campo Grande, and Goiania. For those aged under 50 years, the increased rate was 13.2% in Campo Grande. For those aged over 50 years, there was a significant increase in the mortality in all capitals. In Goiânia, rectal cancer mortality in males increased 7.3%. For females below 50 years of age in the city of Brasilia, there was an increase of 8.7%, while females over 50 years of age in Cuiaba showed an increase of 10%. Conclusion: There is limited data available on the incidence of colon and rectal cancer for the Midwest region of Brazil. Colon cancer mortality has generally increased for both genders, but similar data were not verified for rectal cancer. The findings presented herein demonstrate the necessity for organized screening programs for colon and rectal cancer in Midwestern Brazil.
RESUMO: Objetivo: Descrever o perfil do câncer de cólon e reto no Centro-Oeste do Brasil. Métodos: Os dados de incidência foram obtidos dos Registros de Câncer de Base Populacional (RCBP) de acordo com o período disponível. Dados sobre os óbitos foram obtidos do Sistema de Informação em Mortalidade (SIM). As taxas de incidência e mortalidade foram calculadas por gênero e grupos etários. As tendências de mortalidade foram analisadas pelo software Joinpoint. Os efeitos de idade-período-coorte foram calculados no software R. Resultados: As taxas de incidência do câncer de cólon variaram de 4,49 a 23,19/100.000, e a mortalidade, de 2,85 a 14,54/100.000. A incidência do câncer de reto variou de 1,25 a 11,18/100.000; a mortalidade, de 0,30 a 7,90/100.000. As tendências de mortalidade por câncer de cólon mostraram um aumento entre homens em Cuiabá, Campo Grande e Goiânia. Para aqueles abaixo dos 50 anos, o aumento foi de 13,2% em Campo Grande. Para aqueles acima dos 50 anos, houve um aumento significante em todas as capitais. Em Goiânia, a mortalidade por câncer de reto em homens aumentou 7,3%. Para mulheres abaixo dos 50 anos em Brasília, o aumento foi de 8,7%, enquanto que para mulheres acima dos 50 anos em Cuiabá foi de 10%. Conclusão: Os dados de incidência do câncer de cólon e reto no Centro-Oeste do Brasil são limitados. A mortalidade por câncer de cólon tem aumentado para ambos os sexos, mas o mesmo não foi verificado para câncer de reto. Os resultados demonstram a necessidade de programas organizados de rastreamento para esta neoplasia no Centro-Oeste.
