SMOKING … why is it so important to stop? Well, it is proven to cause harm … proven to cause cancer (carcinogen).  The promotion of smoking cessation is essential, as cigarette smoking is thought to be causal in 85 to 90 percent of ALL lung cancer.

Lung Cancer deathsPrevention, rather than screening, is the most effective strategy for reducing the burden of lung cancer in the long term. Most lung cancer is attributed to smoking, including lung cancer in nonsmokers in whom a significant proportion of cancer is attributed to environmental smoke exposure.

  • Lung cancer is the leading cause of cancer-related death among men and women, and the third leading cause of cancer in the United States
  • Worldwide, lung cancer and lung cancer-related deaths have been increasing in epidemic proportions, largely reflecting increased rates of smoking. studies suggest that for any level of smoking, women are at higher risk of developing cancer than men.
  • In the year 2013, the American Cancer Society predicts that there will be approximately 224,230 new cases of lung cancer diagnosed, and approximately 159,260 lung cancer-associated deaths in the US

Recommendations for screening by expert groups — A 2012 systematic review of available evidence was commissioned by the American Cancer Society (ACS), American College of Chest Physicians (ACCP), American Society of Clinical Oncology (ASCO), and the National Comprehensive Cancer Network (NCCN) to serve as a basis for screening guidelines for these societies.  Screening guidelines supporting low-dose CT scans for identified high-risk groups, based upon this review, were issued by the NCCN and by theACCP/ASCO.

A 2013 systematic review for the US Preventive Services Task Force (USPSTF) serves as the basis for revised guidelines for the USPSTF. Many expert screening groups have incorporated results from the NLST in their recommendations. The recommended age cut-off for screening varies between groups, with modeling studies suggesting that extending screening beyond the 74 years of the NLST cohort will provide further benefit

  • Prevention (promoting smoking cessation) is likely to have far greater impact on lung cancer mortality than is screening. Nonetheless, lung cancer screening has the potential to significantly reduce the burden of lung cancer.
  • Early trials of chest x-ray screening found no mortality benefit for x-ray alone or x-ray plus sputum (spit) cytology
  • Low-dose CT (LDCT) refers to a noncontrast study obtained with a multidetector CT scanner during a single maximal inspiratory breath-hold with a scanning time under 25 seconds. Radiation dose exposure is less than a third of a standard-dose diagnostic chest CT examination.
  • A large randomized trial (NLST) of annual low-dose CT screening in patients with a 30 pack-year history of smoking, including those who quit smoking in the preceding 15 years, demonstrated a decrease in lung cancer and all-cause mortality
  • All patients who smoke should be strongly counselled to quit smoking as the most-effective intervention to reduce the risk of lung cancer.
  • Patients who currently smoke or have a history of smoking should be advised of the risks and benefits of screening for lung:
  • For patients in good health who are thought to have a risk for lung cancer and for whom the cost of screening is not an issue, we suggest annual screening with low-dose helical CT
  • High-risk criteria for participation in the NLST were age 55 to 74 years, a history of smoking at least 30 pack-years and, if a former smoker, had quit within the previous 15 years. Also suggest screening for high-risk patients in good health to age 80
  • Plain chest x-ray screening has been shown to be ineffective for lung cancer screening. We recommend not screening for lung cancer with chest x-ray
