August 3, 2018 17:37

The results of the screening program of lung cancer at the University of Illinois at Chicago suggests that national guidelines for screening, developed on the basis of the National pulmonary or NLST and based on smoking history and age, may be incomplete.

The researchers found that, compared with those of the NLST, a cohort of patients from the screening program lung cancer at the University of Illinois in Chicago, which included a higher percentage of blacks (69.6% vs. 4.5%) and Hispanics (10.6% vs. 1.8%) had a larger number of positive scans (24.6% vs. 13.7%) and a higher percentage of diagnosed cases of lung cancer (2.6% vs. 1.1%).

The study was published in «JAMA Oncology» magazine.

It was one of the first studies, which focused on the screening of national minorities.

"Immunotherapy and other advances in the field of medicine have come a long way to prolonging life and improving quality of life for many people diagnosed with lung cancer, but these achievements are not so important for people who live in areas with a low level of service and are not suitable for screening programs "- reported the scientists. A large group of people with an increased risk of cancer due to factors unrelated to smoking history and age, deprived of the opportunity to participate in the screening.

According to the American Lung Association, African Americans not only have an increased risk of developing lung cancer compared to other ethnic groups, but also more likely to die from the disease. African-American men, for example, die 22% more frequently from lung cancer compared to white men.

"The findings suggest that it is necessary to expand the recommendations for screening" - the researchers report. They believe that when assessing the risk, in addition to smoking history and age, should take into account ethnicity, history of chronic obstructive pulmonary disease, low levels of education and other socio-economic factors.
