Abstract
Background: In Mexico, information on oral and pharyngeal cancer (OPC) is scarce. The purpose of this study was to explore the trends in OPC mortality rates in Mexico from 1979 through 2003 and to describe the distribution of OPC deaths for selected socio‐demographic variables for the period of 2001–2003. Material and methods: Annual crude and age‐adjusted mortality rates were obtained by gender and site of lesion, using the 2003 WHO World standard million population. The Poisson regression model was used to detect a trend in the mortality rates, testing the hypothesis β1 = 0. Also, the annual percentage change (APC) was computed over the age‐adjusted rates. Results: The total number of OPC deaths during the period 1979–2003 was 15 576. The age‐adjusted mortality rate was 1.13/100 000 in 1979 and 1.08/100 000 in 2003. Oral cancer was more frequently found than salivary gland and pharyngeal cancer (41.5% vs. 13.4% and 17.1%). The tongue (19%) was the most frequent oral affected site. The Poisson regression analysis indicated a stationary trend in cancer mortality rate; also, the APC regression model showed no increase or decrease in OPC from 1979 to 2003. Conclusions: Oral and pharyngeal cancer mortality rates in Mexico were low compared to most countries, and remained stable in the past two decades.Keywords
