RESUMEN
INTRODUCTION: In France lung cancer is the second most common cancer in men and the fourth most common in women. In the department of Bas-Rhin the incidence is increasing by 0.1% per annum in men and by 4.4% in women. The aim is to analyse and predict the trend of lung cancer incidence in Bas-Rhin from 1975 to 2014. METHODS: The incidence data from 1975 to 1999 were extracted from the Bas-Rhin cancer registry. Population estimates (2594 years) were made for the period 1975-2014. Predictions were based on a Bayesian age-period-cohort model. RESULTS: Between 1975 and 1999 the incidence of lung cancer increased by 4.5% p.a. in women. In men it increased by 1.6% p.a. between 1975 and 1989 and then diminished. For the periods 2000-2004, 2005-2009 and 2010-2014 respectively the rates should reach 25.6, 32.9 and 42.8 per 100,000 in women and 117.5, 111.6 and 110.1 per 100,000 in men. CONCLUSIONS: Increasing tobacco smoking among women and a reduction among men could be one of the reasons for the respective increasing and decreasing incidences.
