Abstract

BACKGROUND:

The purpose of this study was to analyze and compare incidence trends of oral cavity and oropharyngeal cancers, using data from population-based Spanish cancer registries.

METHODS:

Adjusted rates were calculated using the standard world population, and incidence trends were analyzed for individual and pooled registries using joinpoint regression.

RESULTS:

Analysis of 7 pooled registries revealed a statistically significant reduction in the incidence of oral cavity cancer in men (annual percent change [APC] = -3.1) and a nonsignificant decrease in women (APC = -4.5) over the period from 1991 to 2001. For oropharyngeal cancer, the trend was for a statistically significant increase in men in 4 registries.

CONCLUSION:

There is growing evidence that the incidence of oral cavity cancer is in decline, while the incidence of oropharyngeal cancer has been increasing over the past 3 decades, especially in developed countries, and this study reinforces such evidence.
