There are gender differences in lung cancer mortality trends in Spain, with decreasing rates in men and increasing rates in women. The trends varied among different Autonomous Communities in Spain.
Background: Recently, some countries have shown stable trends in lung cancer death rates among women not yet described for Spain. We propose to update lung cancer mortality rates in Spain during the period of 1980-2018 by sex and region. Methods: We used lung cancer mortality (International Classification of Diseases code 162 for the 9th edition, and codes C33 and C34 for 10th edition) and population data from the Spanish National Statistics Institute for the period 1980-2018. Age-standardised mortality rates (ASMRs), all ages and 30-64 years, by region and sex were assessed through joinpoint regression. Results: During the study period lung cancer ASMRs (all ages) in men decreased -0.4% per annum and increased by 3.1% in women. Recently, ASMR (30-64 years) accelerated its decrease (1992-2007; -0.7 and 2007-2018; -3.5%) in men and slowed its increase (1990-2012; 5.7% and 2012-2018; 1.4%) in women. In men, joinpoint analysis detected an initial period in all Autonomous Communities (ACs) in which the rates significantly increased, followed by a second period in which the rates decreased significantly (12 ACs) or remained stable (4 ACs) since the late 1980s or early 1990s. In women, upward trends in ASMRs (all ages) were observed for the whole period in all the ACs. In 13 ACs, an initial period was detected with joinpoint in which the rates remained stable or significantly decreased, followed by a second period in which the rates increased significantly since the late 1980s or early 1990s. Conclusions: Our study shows gender differences in lung cancer mortality trends in Spain. These differences may be explained by the increased use of tobacco among women and the decreased use among men. (C) 2020 SEPAR. Published by Elsevier Espana S.L.U. All rights reserved.
