2024 World Conference on Lung Cancer (WCLC) - ePosters-EP.17B.04 Racial/Ethnic Differences in Risk of Mortality of Men and Women with Lung Cancer

Pdf Summary

The study analyzed 362,059 cases of invasive lung cancer in California from 2000 to 2021 using data from the California Cancer Registry. It aimed to explore the differences in lung cancer-specific mortality risk among various racial and ethnic groups, particularly focusing on Asian populations, when adjusted for factors like disease stage, treatment types, socioeconomic status (SES), and smoking status.<br /><br />Asian ethnicities were categorized into subgroups such as Middle Eastern, Chinese, Japanese, Korean, Filipino, Southeast Asian, Pacific Islander, and Asian Indian, and were also analyzed under a combined Asian/Pacific Islander (API) category. Cox Regression models were used separately for men and women to compare the risk of lung cancer mortality across these groups against non-Hispanic White individuals, considering three SES strata: lowest, middle, and highest.<br /><br />The key findings of the research indicated that the risk of lung cancer mortality was generally similar among the different Asian ethnicities, showing minimal variation across SES levels. Combining the Asian groups into the API category was found to be sufficient for assessing the mortality risk among Asian lung cancer patients. Specific anomalies were noted, such as Japanese men in the highest SES category displaying an increased risk of mortality compared to their White counterparts. However, for most other Asian ethnicities and within all SES strata, the risk was similar or lower than that for White men and women.<br /><br />The study highlights the potential effectiveness of the API category for broad assessments of mortality risk among Asian patients with lung cancer and suggests that the overall reduced risk might not significantly differ across varying SES levels. This study was presented at the World Conference on Lung Cancer in San Diego in 2024 and was funded by the Sutter Medical Center Foundation.
