More Than 10,000 Lives are saved by Screening CT Scans for Lung Cancer

A new research study has found that more than 10,000 American lives have been saved since the introduction of lung cancer screening for high-risk individuals over the age of 55 and with a history of smoking.

But many general poor people and people from ethnic / racial minorities are still deprived of screening benefits for the world’s leading cause of cancer death, the researchers noted.

To understand or evaluate the effects of the introduction of low-dose CT scans in 2013 for high-risk peoples in the USA(United States), researchers analyzed data from two major cancer regions.

They identified 3.9% increase every year in early (stage 1) non-small cell lung cancer (NSCLC) detection and an average of 11.9% every year of all-cause survival between 2014 and 2018.

According to the authors of the study published March 30 by BMJ, these raises in early detection have saved 10,100 U.S. patients lives.

By 2018, NSCLC was the first primary diagnosis among white American citizens and in areas with the highest incomes people or higher levels of education holding people . However, non-white people and those in poorer or less educated areas of the country are more likely to affected by stage 4 disease at the time of diagnosis.

The study authors further reported that other factors may be increased use of non-screening diagnostic imaging, increased risk of lung cancer diagnoses, and improved cancer stage detection accuracy did not contribute to early growth. The Lung cancer was diagnosed during the study period.

Although the lung cancer screening has slowed down and national screening rates have remained extremely low, the results show that “beneficial effects indicate that there may be fewer screenings for changes in lung cancer stage and population survival,” said Alexandra Potter, an American lungs cancer researcher.

The researchers said the new U.S. Preventive Services Task Force Lung Cancer Screening Guide, which minimizes the high-risk screening age to 50, extends screening eligibility for an additional 6.5 million Americans, with the maximum increase in eligibility among women and ethnic minorities. The new guidelines “present an opportunity to reduce inequality in early detection of lung cancer,” the authors noted in a journal news release.

The research study indicates the real-world benefits of screening lungs cancer in high-risk individuals, according to an assistant editor in the Department of Medicine at the University of Minnesota, Pulmonary, Allergy Critical Care and Sleep Medicine Assistant Professor Dr. Ann Melzer. Medical school, and Dr. Matthew Triplet, an assistant professor at the University of Washington School of Medicine.

But the researchers added that efforts to the screening “should be prioritized to ensure equitable access to screening and to prevent inequalities in the diagnosis of lung cancer and survival levels in the population of different types of patients with lungs cancer.”
