Early screening for lung cancer dramatically increases survival rate for 20 years (research)

Average 5-year survival rate 19% → 20-year survival rate significantly improved to 80%

A study has found that early detection of lung cancer through early screening significantly increases the chances of living a long life.

A research team at Mount Sinai Hospital at Icahn University of Medicine in the United States announced that the 20-year survival rate of cancer patients increased to 80% when early-stage lung cancer was diagnosed through low-dose computed tomography (CT) screening. The research team plans to present this information at the annual meeting of the Radiological Society of North America, which will be held in Chicago from the 27th of this month to the 1st of next month.

According to the research team, the 5-year survival rate for all lung cancer patients is only 18.6%. This is because only 16% of patients are diagnosed with lung cancer at an early stage. More than 50% of lung cancer patients die within 1 year of diagnosis. When symptoms appear, it is already difficult to treat. It can be treated with surgery only if it is detected early, but less than 6% of those who should undergo screening are properly tested.

The United States Special Committee on Disease Prevention and Prevention (USPSTF) recommends annual ‘low-dose CT screening’ to those aged 50 to 80 who have a 20-pack-year smoking history and currently smoke or have quit smoking within the last 15 years. is equivalent to smoking one pack of cigarettes a day for 20 years.

“Screening does not prevent cancer, but it is an important tool for detecting lung cancer at an early stage when it can be removed surgically,” said Claudia Henschker, an interventional radiology professor at the Icahn School of Medicine and lead author of the study. Lung cancer symptoms usually appear in the late stages, so regular checkups should be done early.

The International Early Lung Cancer Screening Program (I-ELCAP) was launched in 1992 at Mount Sinai Hospital of Icahn University School of Medicine. More than 87,000 people from more than 80 institutions have enrolled in the program. The research team followed the 20-year survival rate of 1285 patients diagnosed with early-stage lung cancer who underwent screening in the program.

As a result of the study, the average survival rate for all participants was 80%. The 20-year survival rate of patients (n = 991) with solid nodules (nodules that uniformly and completely cover the lungs) was 73%, and the 20-year survival rate of early patients with cancer areas measured below a certain standard (10 mm) was 92% was The 20-year survival rate for patients with nonsolid nodules and patients with partially solid nodules was 100%.

The results of this study (Lung cancer screening dramatically increases long-term survival rate) were introduced by the American Association for the Advancement of Science portal ‘Eureka Alert’.
