Average 5-year survival rate 19% → Significantly improved 20-year survival rate to 80%
One study found that early detection of lung cancer through early screening significantly increases the chances of living a long life.
A research team from Mount Sinai Hospital of Icahn University of Medicine in the United States has announced that the 20-year survival rate of cancer patients increased to 80% when early stage lung cancer was diagnosed through the 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 receive an early diagnosis of lung cancer. More than 50% of lung cancer patients die within 1 year of diagnosis. When symptoms appear, it is already difficult to treat. It can only be treated with surgery if it’s caught early, but fewer than 6 percent of those expected to be screened are adequately tested.
The United States Special Committee on Disease Prevention and Prevention (USPSTF) recommends annual “low-dose CT screening” for those ages 50 to 80 who have a 20-year smoking history and currently smoke or have quit smoking in the past 15 years is equivalent to smoking a 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 surgically removed,” said Claudia Henschker, professor of interventional radiology at the Icahn School of Medicine and lead author of the study. 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 the Icahn University School of Medicine. More than 87,000 people from more than 80 institutions have signed up for the program. The research team followed the 20-year survival rate of 1,285 patients diagnosed with early-stage lung cancer who were screened 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 evenly and completely cover the lungs) was 73%, and the 20-year survival rate of early patients with tumor areas measured below of a certain standard (10mm) it was 92%. The 20-year survival rate for patients with nonsolid nodules and for patients with partially solid nodules was 100%.
The results of this study (lung cancer screening greatly increases long-term survival rate) were presented by the American Association for the Advancement of Science’s “Eureka Alert” portal.
