Tendências de mortalidade por câncer de boca e orofaringe no Município de São Paulo, Brasil, 1980/2002

Abstract

The current study assessed trends in oral cancer mortality in the city of São Paulo, Brazil, from 1980 to 2002. The official mortality information system supplied data on deaths whose underlying cause was classified as oral cancer, stratified by sex, age, and anatomic site. Death rates were estimated and adjusted by the direct method, using population data supplied by national censuses from 1980, 1991, and 2000 and a population count performed in 1996. There was an upward trend in overall cancer mortality, at a yearly rate of 0.72%. Accounting for more than one third of these deaths, tongue cancer was the main mortality category. Labial, gengival, and retromolar cancer showed a downward trend, while oropharyngeal cancer and cancer in unspecified parts of the mouth and oropharynx showed increasing mortality. Monitoring the magnitude and trends in cancer mortality can assist the planning of health initiatives aimed at reducing the disease burden from oral cancer in Brazil.

Epidemiological Profile of Patients with Oral and Oropharyngeal Cancer Treated at a Referral Hospital, Salvador, Brazil

“…Therefore, these results are in accordance with the scientific literature, especially regarding the age of the individuals, since the records reveal that 95% of cases of oral cavity cancer occurred in people aged 40 years or more, and that the average age at the time of diagnosis was during the sixth decade of life [3,[5][6][7][8][9].…”

Oral carcinoma epidemiology in Paraná State, Southern Brazil

“…Cancers of the oral cavity include those involving the lips, tongue, gingiva, floor of mouth, palate, salivary glands, tonsils, and oropharynx. The etiology is multifactorial, including endogenous factors such as genetic susceptibility as well as environmental and lifestyle exogenous factors like smoking and alcohol consumption 2 .…”

Oral Cancer Screening in Elderly in Sao Paulo State, Brazil (2001 to 2009)

“…The estimation of annual growth or decline of each variable was performed by Prais-Winsten procedure [11], a generalized linear regression to make correct first-order autocorrelation in the analysis of sets of values organized overtime. To control the effectiveness of using this methodological approach, we used the Durbin-Watson statistic to measure the existence of firstorder autocorrelation of the series consisting of the annual rates; also, to check whether the correction was compatible with the hypothesis of residual regression with random distribution [10][11][12].…”
