Racial/ethnic and geographic differences in second primary cancers in stomach cancer survivors: a comparative study of U.S. and South Korea
To estimate the risk of second primary cancers (SPCs) and evaluate post-SPC survival among stomach cancer survivors, with a focus on racial/ethnic and geographic differences.
Key Findings:
5.4% of U.S. stomach cancer survivors developed SPCs, with the highest rates in White patients (6.2%).
In South Korea, 3.4% of stomach cancer patients developed SPCs.
Korean American patients had the highest SPC proportion among Asian subgroups in the U.S. (5.3%).
Differences in patient characteristics were observed, including stage at diagnosis and histologic subtype distributions.
Interpretation:
The study highlights significant racial/ethnic and geographic disparities in the incidence of SPCs among stomach cancer survivors, suggesting the need for tailored surveillance and intervention strategies.
Limitations:
Potential misclassification bias in SPC definitions may affect the accuracy of results.
Limited generalizability due to the focus on specific national databases.
Exclusion of patients with distant-stage disease may affect the overall findings.
Conclusion:
Understanding the variations in SPC risk and survival outcomes can inform targeted strategies for monitoring and managing stomach cancer survivors across different populations, ultimately improving clinical practice.
