Trends in laryngeal cancer incidence in a health area between 2007 and 2013.

OBJECTIVE: Our aim was to study the trend between 2007 and 2013 in the incidence of larynx cancer in a health district of 300,000 inhabitants. MATERIAL AND METHOD: With information from the hospital cancer registry for the reference health area, we calculated the incidence and subsequently performed a joinpoint regression using specific software. RESULTS: We found a statistically-significant downward trend with an annual percentage change of -10.83 LC 95% (-16.85, -4.40) between 2007 and 2013. CONCLUSIONS: We found that the tendency of incidence in larynx cancer decreased, mainly in males, where the results were statistically significant. These results should encourage continuing prevention of smoking and alcohol consumption.
