Introduction Cuba is one of the countries with the highest rates of incidence of and mortality from laryngeal cancer. Objectives To identify the geographical distribution of the incidence of and mortality from laryngeal cancer in the 1999-2004 period. Methods The new cases reported to the National Register of Cancer from 1999 to 2003 as well as the deaths occured in the period of 2000 to 2004 were taken into consideration. Age-standardized average incidence and mortality rations for both periods were estimated. The standard risk was the specific average incidence and mortality rates by age groups in Cuba for the respective periods. The cartographic representation of the estimated risk was made. Results The risk of getting sick and dying was higher in men than in women. Regarding men, the risk of getting sick was significantly higher in Villa Clara, Matanzas, Ciudad de la Habana and Isla de la Juventud whereas the highest risk of dying was observed in Gramma, Ciudad de La Habana, Holguín and Isla de la Juventud. The risk of getting sick for women did not show significant regional differences whereas the risk of dying was substantially higher in Pinar del Río. Conclusions The regional differences in the risk of getting sick and dying from laryngeal cancer may suggest that later diagnosis and less timely therapies in some provinces could have been the causes. These findings should be an alert to the health authorities in terms of the review of the compliance with diagnosis and treatment guidelines and the development of professional formation and updating programs.
