RESULTS: Mean age was 59 years, two thirds were male; more than half of patients were current or former smokers (56.7%). Smoking status was not documented in 17% of patients. Lung cancer was the most common malignancy among study participants with a prevalence of 7.3%, followed by breast cancer (4.4%), colon cancer (3.5%), and prostate cancer (2.7%), respectively. Bronchitis, both acute and chronic, was present in 5.7 % of patients. Pulmonary embolism was prevalent in 2.6 % of patients. In multivariate analyses, age ≥ 65 (adjusted OR 2.3, p = 0.04), male gender (adjusted OR 2.5, p = 0.05) and history of diabetes (adjusted OR 2.7, p = 0.03) were associated with statistically significant increased odds of having lung cancer among patients seen. There was also a trend toward and increased odds in patients with COPD although this did not achieve statistical significance (adjusted OR 2.2, p = 0.06).
