Abstract | |||
This study evaluates etiology for lung cancer and related diseases (e.g. COPD/emphysema) among screening arm participants in the PLCO Trial, a randomized control trial to evaluate the effectiveness of screening for prostate, lung, colorectal and ovarian cancer. The study includes about 75,000 subjects, aged 55-74 years, recruited at 10 U.S. Screening Centers. The study is identifying risk factors for smoking behavior, lung cancer and related diseases. Currently, we are evaluating a panel of genetic polymorphisms involving genes controlling pathways related to nicotine or neurotransmitters (dopamine, serotonin) that may be related to the smoking phenotype. This analysis will involve 1000 current and 1000 former smokers, matched on age, gender, and smoking intensity. We will be able to isolate selected subpopulations of smokers for special study, including heavy smokers (i.e., intensity greater than 20 cigarettes per day) and chippers (fewer than 5 cigarettes per day). Obesity, medical conditions related to tobacco use (emphysema, bronchitis, other cardiac and respiratory conditions) and alcohol intake will be taken into account in the analysis. |
