ABSTRACT

CONTEXT AND OBJECTIVE: Studies have shown increased prevalence rates for breast cancer, relating to higher incidence, longer survival and breast cancer prevention programs among populations. The aim here was to analyze the annual prevalence of breast cancer in Goiânia over a 15-year period. DESIGN AND SETTING: This was a cross-sectional study on women with breast cancer diagnosed in Goiânia, Goiás, Brazil, from 1988 to 2002. METHODS: The breast cancer cases were identified in the database of the Population-Based Cancer Registry of Goiânia. The 15-year period was stratified into three five-year periods. The cases were followed up for five years, and the mortality database was used to exclude deaths. The population of the official census was used as the denominator for rate calculations. RESULTS: The coefficient of breast cancer prevalence in Goiania was 22.87/100,000 in 1988 and 220.22/100,000 women in 2002. The analyses for periods showed that in the first period, the rate was 19.39/100,000 and that it was 44.79/100,000 in the last period. For the fifteen years analyzed, the prevalence rate for breast cancer was 127.24/100,000 women. The annual percentage change was 27.07 (P < 0.001; 95 percent confidence interval, CI: 20.79-33.67) from 1988 to 1992 and 9.39 (P < 0.001; 95 percent CI: 8.52-10.25) from 1992 to 2002. CONCLUSION: There was an increase in the breast cancer prevalence rate in the city of Goiânia between 1988 and 2002, possibly relating to the improvement in the screening and treatment of breast cancer.


CONTEXO E OBJETIVO: Estudos têm demonstrado um aumento da taxa de prevalência para o câncer de mama relacionado à maior incidência, maior sobrevida e programas de prevenção do câncer de mama na população. O objetivo foi analisar a prevalência anual de câncer de mama em Goiânia, num período de 15 anos. TIPO DE ESTUDO E LOCAL: Estudo de corte transversal de mulheres com câncer de mama em Goiânia, Goiás, Brasil, no período de 1988 a 2002. METODOS: Os casos de câncer de mama foram identificados na base de dados do Registro de Câncer de Base Populacional de Goiânia. Os 15 anos foram estratificados em quinquênios. As pacientes foram seguidas por cinco anos e utilizaram-se os dados da mortalidade para exclusão dos óbitos. Utilizou-se a população do censo oficial como denominador para o cálculo das taxas. RESULTADOS: O coeficiente de prevalência de câncer de mama em Goiânia foi de 22,87/100000 em 1988 e 220,22/100000 mulheres em 2002. As análises para os períodos evidenciaram que, no primeiro período, a taxa foi de 19,39/100000, e de 44,79/100000 no último período. Nos 15 anos de análise, a taxa de prevalência foi de 127,24/100000 mulheres. A mudança percentual anual foi de 27,07 (P < 0,001; intervalo de confiança, IC 95 por cento 20,79-33,67) de 1988 a 1992 e 9,39 (P < 0,001; IC 95 por cento 8,52-10,25) de 1992 a 2002. CONCLUSÃO: Houve aumento da taxa de prevalência do câncer de mama na cidade de Goiânia no período de 1988 a 2002, possivelmente relacionado à melhora do rastreamento e do tratamento do câncer de mama.

ABSTRACT

CONTEXT AND OBJECTIVE: It has been suggested that there has been a large increase in breast cancer incidence among young women over the last decade. The aim of this study was to describe the incidence of breast cancer among young women up to 39 years of age in Goiânia, between 1988 and 2003, and to compare this with other age groups. DESIGN AND SETTING: Retrospective study using the database of the Population-based Cancer Registry of Goiânia, State of Goiás, Brazil. METHODS: The incidence was calculated according to age groups: up to 39 years, 40 to 59 years and 60 years and over. Average annual percentage changes (AAPCs) were estimated for the different age groups using Poisson regression. RESULTS: Over this period, 3,310 new cases were recorded. The standardized incidence was 2.89/100,000 in 1988 and increased to 6.37/100,000 in 2003 (R² = 0.52) for the group aged up to 39 years (p < 0.003). For the group from 40 to 59 years old, the incidence was 14.39/100,000 in 1988 and 41.70/100,000 in 2003 (R² = 0.85; p < 0.001). For the group aged 60 years and over, it was 17.62/100,000 and 28.49/100,000, respectively (R² = 0.67; p < 0.001). The AAPCs were 5.22 percent, 5.53 percent and 4.54 percent for the age groups up to 39, 40 to 59 and 60 years and over, respectively. CONCLUSIONS: The incidence of breast cancer among young women in Goiânia has been increasing significantly, although this change was similar to the increase in other age groups.


CONTEXTO E OBJETIVO: Tem sido sugerido que há um grande aumento na incidência do câncer de mama em mulheres jovens na última década. O objetivo deste estudo é descrever a incidência do câncer de mama em mulheres jovens (até 39 anos) em Goiânia, entre 1988 e 2003, comparando com os demais grupos etários. DESENHO E LOCAL: Estudo retrospectivo utilizando o banco de dados do Registro de Câncer de Base populacional de Goiânia/Goiás, Brasil. MÉTODOS: As incidências foram calculadas de acordo com os grupos etários: até 39 anos, 40 a 59 anos e, 60 anos acima. A mudança da média percentual anual (MMPA) foi estimada para os diferentes grupos usando a regressão de Poisson. RESULTADOS: No período, foram registrados 3.310 novos casos. A incidência padronizada foi de 2,89/100.000 em 1988 tendo aumentado para 6,37/100.000 em 2003 (R² = 0,52) para o grupo com até 39 anos (p < 0,003). Para o grupo de 40 a 59 anos a incidência foi de 14,39/100.000 em 1988 e de 41,70/100.000 em 2003 (R² = 0,85; p < 0,001); para o grupo de 60 anos e acima foi de 17,62/100.000 e 28,49/100.000, respectivamente (R² = 0,67; p < 0,001). A MMPA foi de 5,22 por cento, 5,53 por cento e 4,54 por cento para os grupos etários de até 39 anos, 40 a 59 e 60 ou mais, respectivamente. CONCLUSÕES: A incidência de câncer de mama em mulheres jovens em Goiânia vem aumentando significativamente, entretanto esse aumento é semelhante ao observado nos demais grupos etários.

ABSTRACT

OBJETIVO: Analisar a mudança temporal do estádio clínico do câncer de mama ao diagnóstico em mulheres residentes em Goiânia entre 1989 e 2003. MÉTODOS: estudo retrospectivo, utilizando-se a base de dados do Registro de Câncer de Base Populacional de Goiânia. As variáveis estudadas foram: idade, diagnóstico histológico, localização do tumor, tipo histológico e estádio clínico da doença. O período estudado foi dividido em três quinquênios: de 1989 a 1993, de 1994 a 1998 e de 1999 a 2003. Utilizou-se o teste Z para comparação das frequências da extensão ao diagnóstico por quinquênio. RESULTADOS: foram identificados 3.204 casos de câncer de mama. A média de idade foi de 56 anos (dp±16 anos). Quanto ao estádio da doença, evidenciou-se que 45,6% dos casos eram localizados na mama, com aumento de 19,2% entre o primeiro e o terceiro quinquênio (p<0,001; IC95%=0,14-0,23) e 10,2% de casos eram metastáticos, Entretanto, foi observada uma redução de 17,7% para os casos metastáticos no mesmo período (p<0,001; IC95%=0,14-0,21). A taxa de casos in situ entre 1989 e 1993 foi de 0,2%, aumentando para 6,2% em 1999-2003 (p<0,001; IC95%=4,9-7,4). CONCLUSÃO: observou-se um aumento dos casos de carcinoma in situ e de carcinomas invasores localizados somente na mama em detrimento de uma redução dos casos com metástases linfonodais e à distância.


PURPOSE: To analyze the temporal changes of breast cancer staging at diagnosis among women living in Goiânia, Goiás, Brazil, between 1989 and 2003. METHODS: Retrospective and descriptive study in which the cases were identified from the Population-Based Cancer Registry of Goiânia for the period from 1989 to 2003. The variables studied were age, diagnostic method, topographic sublocation, morphology and breast cancer staging. Frequency analyses were carried out on the variables and means, and the medians for the age were determined. The SPSS® 15.0 software was used for statistical analyses. RESULTS: A total of 3,204 breast cancer cases were collected. The mean age was 56 years (sd±16 years). With regard to clinical staging, 45.6% of the cases were found to be localized in the breast, with an increased rate of 19.25% between the first and the third five-year period (p<0.001; CI 95%=0.14-0.23) and 10.2% of cases were with distant metastases. However, a reduction of 17.74% for metastatic cases in the same interval (p<0.001 e CI 95%=0.14-21) was observed. The in situ case rate was 0.2% in 1989-1993 and increased to 6.2% in 1999-2003 (p<0.001, IC95%=4.9-7.4). CONCLUSION: The diagnostic profile of breast cancer in the city of Goiânia is changing. Substantial increases in the number of early breast cancer cases are being found in relation to the number of advanced cases.

ABSTRACT

In developed countries, oral cancer is the eightieth most common cancer type, whereas in the developing world it is the fourth most common type of the disease. Known risk factors for oral cancer are smoking, alcohol consumption, poor oral hygiene, poorly-fitting dentures. This study analyzed sociodemographic and dietary factors as risk factors for cancer of the mouth and oropharynx. Patients and Methods: This case-control study was carried out from November 1998 to June 2003. The cases were patients with a diagnosis of squamous cell carcinoma of the mouth and oropharynx at the Araujo Jorge Hospital in Goiania, Goias, Brazil. Controls were selected in two public general hospitals of Goiania with no oncologic departments. Results: The study consisted of 200 cases (41.8%) and 279 controls (58.2%). Multivariate analysis, adjusted for smoking, alcohol consumption and place of residence, showed that fish, fresh tomatoes, citric fruit, apples and pears consumption was a protective factor, while cakes and desserts remain as independent risk factors. Conclusions: Dietary habits are important in the prevention of oral and oropharyngeal cancer. Healthy dietary habits should be stimulated through educational campaigns, the objective of which should also be to combat alcohol and tobacco consumption.
