Which cancer causes the most deaths in the United States annually? - Lung cancer is the leading cause of cancer death in the United States overall, followed by colorectal cancer. Prostate cancer and breast cancer are the second leading causes of cancer death in men and women, respectively, (but not overall). Which of the following individuals meet the current (2014) USPSTF criteria for undergoing chest CT screening for lung cancer? A) 60 year-old female who is a current smoker with a 25 pack-year history of smoking. B) 65 year-old male former smoker with a 30 pack-year history of smoking who quit smoking 15 years ago. C) 55 year-old female former smoker with a 30 pack-year history of smoking who quit smoking 10 years ago. D) 50 year-old male who is a current smoker with a 30 pack-year history of smoking. - Answer: C. In 2014, the USPSTF issued a "B" recommendation for screening for lung cancer with low dose CT scans. The recommendation was based on the results of the US National Lung Screening Trial (NLST), a large randomized clinical trial published in 2011 showing a reduction of lung cancer deaths in the group undergoing annual low dose CT scans for lung cancer screening over 3 years compared with the group undergoing annual chest x-rays. The inclusion/exclusion criteria for the trial were used as the basis for the recommended screening group in the new guideline: Current or former smoker ages 55-80 years with at least a 30 packyear history of smoking and who has quit less than 15 years ago.
