P3.01D.02 Lung Cancer Incidence Trends by Histology and Sociodemographic Characteristics in the US from 2000-2019

Pdf Summary

The study conducted by Jihyoun Jeon and colleagues assessed lung cancer (LC) incidence trends in the US from 2000 to 2019, focusing on differences by histological subtypes, sociodemographic factors, and urbanicity. The research utilized data from the Surveillance, Epidemiology, and End Results (SEER) program covering 27% of the US population.<br /><br />Key findings indicate that while overall lung cancer incidences are decreasing due to declining smoking trends, variations exist across different subtypes and demographics. Specifically, adenocarcinoma incidences have remained relatively stable, even increasing in proportion among other lung cancer cases. Different racial and ethnic groups exhibited diverse trends, with notable decreases not uniformly distributed. Non-Hispanic Whites, Non-Hispanic Blacks, and Non-Hispanic American Indian and Alaska Natives had the highest incidences.<br /><br />Analysis revealed that small cell and squamous cell lung cancer incidences are declining in all regions, with faster drops observed in males and in counties with higher education and wealth levels. Notably, urban areas experienced more rapid decreases in LC incidences than rural areas, except in adenocarcinoma cases, where rural vs. urban disparities remain.<br /><br />The research highlights complex intersections of race, gender, and socioeconomic status in lung cancer trends, suggesting persistent health disparities. To address these disparities, the study emphasizes the importance of improving healthcare accessibility and addressing structural inequities that affect vulnerable populations disproportionately.<br /><br />The study's outcomes call for targeted healthcare interventions and policy changes to tackle sociodemographic and regional inequities in lung cancer incidence and to improve overall public health equity.
