Abstract
PurposeLung cancer is the second most frequently diagnosed cancer among men and women in the United States. With cigarette smoking causing the majority of cases, patterns in lung cancer are often monitored to understand the impact of anti-tobacco efforts. The purpose of this research was to investigate trends in lung cancer incidence rates for the period 2005–2010 in Oklahoma.MethodsData on Oklahoma’s incident cases of lung cancer (2005–2010) were obtained from the Centers for Disease Control and Prevention WONDER system. Annual percent change (APC) was calculated by linear regression to characterize trends in lung cancer incidence rates over time for the overall population, by gender, by age group, and by age group within gender. Rates were considered to increase or decrease if the p-value for trend was <0.05.ResultsFrom 2005 through 2010, lung cancer incidence rates declined from 81.96 to 68.19 per 100,000 population, with an APC of -3.58% (p-value: 0.0220). When subgroups were examined, declines were observed among all males (APC: -4.25%; p-value: 0.0270), males <65 years (APC: -5.32%; p-value: 0.0008), females <65 years (APC: -4.85%; p-value: 0.0044), and persons aged 55–64 years (APC: -6.38%; p-value: 0.0017).ConclusionsDeclines in lung cancer incidence rates occurred during 2005–2010 among the overall population and within select demographic groups in Oklahoma. Although trends were stable for several demographic groups, rates of lung cancer incidence were lower in 2010 compared to 2005. Continued evidence-based tobacco control efforts are needed to ensure further reductions in lung cancer incidence rates in the state of Oklahoma.
Highlights
Lung cancer is the second most frequently diagnosed cancer among men and women in the United States [1]
Trends were stable for several demographic groups, rates of lung cancer incidence were lower in 2010 compared to 2005
The findings of the Centers for Disease Control and Prevention (CDC) report on lung cancer declines are hailed as a major achievement of tobacco control, as significant reductions in lung cancer are largely attributed to a multicomponent approach to tobacco prevention and control which involves evidence-based strategies such as cessation services including state quitlines, taxing cigarettes, smoking bans, and media counter-advertising
Summary
Lung cancer is the second most frequently diagnosed cancer among men and women in the United States [1]. Cigarette smoking and secondhand smoke exposure cause the majority of lung cancer cases and an estimated 80 to 90% of lung cancer deaths [3]. A recent report by the Centers for Disease Control and Prevention (CDC) showed statistically significant declines in lung cancer incidence among US men and women from 2005 to 2009 [7]. Geographic variations in lung cancer trends may reflect variability in smoking prevalences that are the result of differing investments in tobacco control and prevention [8]. The findings of the CDC report on lung cancer declines are hailed as a major achievement of tobacco control, as significant reductions in lung cancer are largely attributed to a multicomponent approach to tobacco prevention and control which involves evidence-based strategies such as cessation services including state quitlines, taxing cigarettes, smoking bans, and media counter-advertising
