To detect lung cancer, the lung scanner is preferred in the United States and not in France. A new report from the Tufts Medical Center challenges this strategy by advocating for screening based on the individual risk score.
Individual risk lung cancer screening has the potential to save more lives than the current US Preventive Services Task Force (USPSTF) recommendations that use lung scans.
The USPSTF recommends low-dose annual lung cancer screening for people aged 55 to 80 who smoke or quit in the last 15 years.
This can be explained by the fact that these criteria do not include other high-risk individuals with lung cancer who would have been selected by individual risk calculators that only consider demographic, clinical and smoking characteristics.
Cost-effectiveness changes the game
Most of the current recommendations for lung cancer screening, including those for the USPSTTF, use screening criteria based on the results of the national lung test.
Researchers at Tufts Medical Center have compared the cost-effectiveness of different types of screening by estimating life years adjusted for the quality of these strategies (QS). The authors explain that lung cancer is still one of the most deadly types of cancer in the United States and that early detection and treatment is an effective way to improve life expectancy.
Although the identification of individuals to be screened is based on the individual risk based on a risk score is greater than the CT scan, the real question is why screening, regardless of its method, are not subjected to screening most often.
