Revisiting gastric cancer disparities in Asian American subgroups: insights from the SEER database

CONCLUSIONS: Substantial heterogeneity persists in clinicopathological features, survival, and temporal trends among Asian American subgroups, with South Asian now demonstrating the most favorable survival outcomes and consistent increases in early diagnosis, cardia tumors, and systemic therapy use. These findings help identify factors underlying this heterogeneity and develop strategies to reduce incidence, improve early detection, and mitigate survival disparities.
