Dietary patterns and risk of oral and pharyngeal cancer: a case-control study in Rio de Janeiro, Brazil / Padrões dietéticos e câncer oral e de faringe: um estudo caso-controle no Rio de Janeiro, Brasil

The study investigated the association between dietary patterns and oral cancer as part of a Latin American multicenter hospital-based case-control study, and included 210 incident cases of oral cancer and 251 controls. Dietary data were collected using a Food Frequency Questionnaire (FFQ). Factor analysis was used to define dietary patterns, which were categorized into terciles. Odds ratios (OR) with 95 percent confidence intervals (95 percentCI) were calculated using unconditional multiple logistic regression. The patterns "prudent", characterized mainly by vegetables and fruits, and "traditional", by rice, and pulses showed an inverse association with oral cancer for the higher tercile, respectively, OR = 0.44; 95 percentCI: 0.25-0.75, p value for trend (p tend) = 0.03; OR = 0.53; 95 percentCI: 0.30-0.93, p tend = 0.06. The "snacks pattern" was not associated with oral cancer. Besides the protective effect of a diet rich in vegetables and fruit, our data suggest that the traditional Brazilian diet, consisting mostly of rice and beans, may improve protection against oral cancer.

Investigou-se a associação entre padrões de dieta e câncer oral, como parte de um estudo multicêntrico latino-americano caso-controle de base hospitalar e incluiu 210 casos incidentes e 251 controles. Dados de consumo alimentar foram coletados por Questionário de Freqüência de Consumo Alimentar (QFCA). Análise fatorial identificou padrões alimentares, que foram categorizados em tercis. Calculou-se odds ratio (OR) com intervalo de 95 por cento de confiança (IC95 por cento) por regressão logística múltipla não condicional. Os padrões "prudente", caracterizado em maioria por frutas e vegetais, e o padrão tradicional, por arroz e feijão, apresentaram associação inversa com o câncer oral para o mais elevado tercil, respectivamente: OR = 0,44; IC95 por cento: 0,25-0,75, valor de p de tendência (p tend) = 0,03; OR = 0,53; IC95 por cento: 0,30-0,93, p tend = 0,06. O padrão "lanches" não foi associado ao câncer oral. Além da proteção ao câncer oral conferida por dieta rica em vegetais e frutas, nossos dados sugerem que a dieta "tradicional" brasileira contendo em sua maioria arroz e feijão pode oferecer proteção ao câncer oral.

Se revisó toda la bibliografía haciendo énfasis en la encontrada de los últimos cinco años. Se realizó la revisión de revistas que han publicado artículos sobre el tema en cuestión y otras fuentes bibliográficas impresas, como libros y folletos lo cual arrojó que con la implementación del mismo se ha logrado mantener en nuestro país la curabilidad del cáncer bucofaríngeo al más alto nivel internacional.
