Pdf Summary

This study aimed to evaluate the impact of lung cancer screening with low-dose chest computed tomography (LDCT) scan in an elderly population. The study enrolled patients aged 70 years and older who underwent screening. The lung cancer detection rate was evaluated, as well as the characteristics of patients, type of treatment, and survival rates. <br /><br />A total of 1,530 patients were included in the study, with 1,020 patients in the 70-75 age group and 510 in the 75 and older age group. The overall lung cancer detection rate was 3.1%. The lung cancer detection rate in the older age group was similar to that in the 70-75 age group, but current smokers in the older age group had a significantly higher detection rate than those in the 70-75 age group. <br /><br />The overall survival of patients with screen-detected lung cancer was higher than that of patients with non-screening detected lung cancer. However, when the analysis was confined to the older age group, the survival rate of patients with screen-detected lung cancer did not significantly differ from that of patients with non-screening detected lung cancer.<br /><br />The study concludes that lung cancer screening with LDCT scan played a significant role in detecting lung cancer in the elderly population. However, the survival benefit in the population over 75 was not confirmed due to a limited number of patients. Further prospective studies on lung cancer screening in the elderly population should be performed.
