International variation in lung cancer mortality rates and trends among women.
BACKGROUND
There is no recent comprehensive global analysis of lung cancer mortality in women. We describe contemporary mortality rates and trends among women globally.


METHODS
We used the World Health Organization's Cancer Mortality Database covering 65 populations on six continents to calculate age-standardized (1960 Segi world standard) lung cancer death rates during 2006 to 2010 and annual percent change in rates for available years from 1985 to 2011 and for the most recent five data years by population and age group (30-49 and 50-74 years).


RESULTS
Lung cancer mortality rates (per 100,000) among young women (30-49 years) during 2006 to 2010 ranged from 0.7 in Costa Rica to 14.8 in Hungary. Rates among young women were stable or declining in 47 of 52 populations examined. Rates among women 50 to 74 years ranged from 8.8 in Georgia and Egypt to 120.0 in Scotland. In both age groups, rates were highest in parts of Europe (Scotland, Hungary, Denmark) and North America and lowest in Africa, Asia, and Latin America. Rates in older women were increasing for more than half (36/64) of populations examined, including most countries in Southern, Eastern, and Western Europe and South America.


CONCLUSIONS
Although widespread reductions in lung cancer in young women provide evidence of tobacco control success, rates continue to increase among older women in many countries.


CONCLUSIONS
More concentrated efforts to initiate or expand tobacco control programs in these countries globally will be required to attenuate the future lung cancer burden. Cancer Epidemiol Biomarkers Prev; 23(6); 1025-36. ©2014 AACR.
