Introduction: Cuba is one of the countries with higher laryngeal cancer incidence and mortality rates in both sexes, being the fourth in terms of relative significance for males. Objectives: to provide updated information and analyze the recent changes in the tendency of laryngeal cancer incidence rates in Cuba from 1988-2003 Methods: Using data from the National Cancer Register and the estimated population during the 1988-2003 period, the time tendency of laryngeal cancer incidence rates was studied. Crude, specific and standardized (global and truncated) rates were estimated. The jointpoint regression method served to estimate the yearly change percentage and to identify points of change in the tendency. Results: Collected data showed that laryngeal cancer was more common after 60 to 70 years of age ranging 5-6 men per woman approximately. From 1988 to 2003, the overall age-adjusted rate varied from 8.4 per 100 000 to 10.4 per 100 000 for men, with a statistically significant (p<0,05) annual average increase of 1.44 % whereas that change was not statistically significant for females. After a statistically significant rise in 1999, it was observed that incidence rates exhibited an incipient fall in men, which is indicative of a possible relation with a drop in smoking and alcoholism prevalence from 1995 to 2001 according to data from the national survey of risk factors and communicable diseases (I and II). Conclusions: It is necessary to continue working at all levels to achieve substantial accomplishments in ceasing smoking and alcoholism and mainly, in preventing young people from falling into these habits which are fundamental putative risk factors of head and neck cancers.
