Abstract

Abstract: Introduction: The incidence of lip, oral cavity and oropharynx cancer in Brazil is one of the highest worldwide.

Objective: This study aimed to identify predictors for oral cancer in Brazil between 2010 and 2013.

Method: Through a time series study in which 14,959 primary head and neck cancer diagnoses were evaluated. The variables of interest were gender, age, race, education level, family history of cancer, alcohol consumption, smoking, and previous cancer diagnosis. The outcome variable was divided into “oral cancer” and “cancer of other head and neck regions.” The data were analysed by multiple binary logistic regression; α=5%.

Result: The protective factor was: approximately 12 years of education (OR = 0.85). The risk factors were: being an ex-consumer (OR=1.19) or consumer (OR=1.11) of alcohol, tobacco use (OR=1.35) and a prior diagnosis of cancer that went untreated (OR=1.21).

Conclusion: Was concluded that the oral cancer had the following predictors compared to other types of head and neck cancer during the same period: approximately 12 years of education (protective factor) and ex-consumer or consumer of alcohol, smoking and previous diagnosis of cancer that went untreated (risk factors).

Resumo

Resumo: Introdução: A incidência de câncer de lábio, cavidade bucal e orofaringe no Brasil é uma das maiores do mundo.

Objetivo: Este estudo teve como objetivo identificar preditores para o câncer bucal no Brasil entre 2010 e 2013.

Método: Mediante um estudo de série temporal em que foram avaliados 14.959 diagnósticos primários de câncer de cabeça e pescoço. As variáveis de interesse foram: gênero, idade, raça, nível de escolaridade, histórico familiar de câncer, consumo de álcool, tabagismo e diagnóstico anterior de câncer. A variável desfecho foi dividida em “câncer de boca” e “câncer de outras regiões de cabeça e pescoço”. Os dados foram analisados por regressão logística binária múltipla; α = 5%.

Resultado: O fator de proteção foi: ter aproximadamente 12 anos de escolaridade (OR = 0,85). Os fatores de risco foram: ser um ex-consumidor (OR = 1,19) ou consumidor (OR = 1,11) de álcool, tabagismo (OR = 1,35) e o diagnóstico prévio de câncer sem tratamento (OR = 1,21).

Conclusão: Concluiu-se que o câncer bucal possui os seguintes preditores em comparação com outros tipos de câncer de cabeça e pescoço durante o mesmo período: ter aproximadamente 12 anos de estudo (fator de proteção) e ser ex-consumidor ou consumidor de álcool, tabagismo e ter tido um diagnóstico prévio de câncer sem tratamento (fatores de risco).
