Low Dose, CT Lung Cancer Screening
Partners Imaging is offering low dose CT scans for lung cancer screening. A physician’s order is required.
Lung Cancer is the leading cause of cancer-related deaths in the United States and represents about 25% of all cancer deaths. It is estimated that in the US, over 90 million individuals have a history of cigarette smoking, with approximately half reported to be current smokers. Stopping smoking reduces the risk for lung cancer; however, former smokers remain at an elevated risk compared to individuals who never smoked.
Based on the National Lung Screening Trail (NLST), involving over 53,000 current and former heavy smokers, compared to standard chest x-ray, the mortality rate for lung cancer deaths was 20% lower in the group screened with low dose helical CT scans. The goal of early detection of lung cancer by using low dose CT is to find it when it’s most curable.
The study shows yearly low dose CT scans to be safe and effective in screening high risk individuals for lung cancer before symptoms appear. High risk individuals were defined as 55 to 74 years old with more than a 30 pack-year smoking history (i.e. smoked one pack of cigarettes per day for 30 years or 2 packs per day for 15 years, etc.).
The study is published in the New England Journal of Medicine:
