2023 World Conference on Lung Cancer (Posters)-P1.22. Biomarker Testing Trends from a Global Patient-Reported Outcomes Registry

Pdf Summary

A study analyzed data from a real-world patient-reported outcomes registry to understand the trends in biomarker testing for patients with advanced non-small cell lung cancer. The study revealed that there is considerable variability in testing rates for patients with lung cancer, despite clinical guidelines recommending testing for all individuals. The analysis was conducted using a registry, called the Lung Cancer Registry, which collects surveys from patients with lung cancer to track their treatment journey. The study included data from 2019 to 2022 for patients diagnosed between 2003 and 2022.<br /><br />The results showed that biomarker testing rates decreased with age, with patients under 40 having the highest rates (96.4%), while those over 80 had the lowest (77.8%). Patients with small cell lung cancer had a lower rate of testing (27%), compared to non-small cell lung cancer patients. Testing rates also varied by stage, with early-stage patients having lower rates (69%) compared to later-stage patients. Additionally, patients with no smoking history had higher testing rates (95.5%) compared to smokers (80.6%).<br /><br />The study revealed disparities in biomarker testing rates, with age, stage, histology, and smoking history being significant factors. Younger patients, stage IV patients, non-small cell lung cancer patients, and patients without a smoking history were more likely to receive testing. These findings highlight the need for patient education and addressing barriers to testing, especially among medically underserved populations.<br /><br />The study concludes that there is a need for further research to understand and address these disparities in biomarker testing rates. It is important to ensure equal access to testing and improve patient education to reduce gaps in knowledge. These disparities may be more pronounced in medically underserved populations, such as people of color, LGBTQ individuals, rural residents, uninsured/underinsured individuals, and low-income individuals.
