More stomach cancers are being caught earlier, offering hope for improved outcomes. But for Black and Asian Americans, the risk remains disproportionately high. A recent study led by Mohamed Tausif Siddiqui, MD, found that diagnoses of localized gastric cancer rose by 53% between 2004 and 2021, while advanced-stage cases declined. The shift is credited to better technology and increased clinical attention to subtle gastrointestinal symptoms.
However, the overall number of cases is climbing, and early-onset gastric cancer—affecting people under 50—is often more aggressive. It’s more likely to involve high-grade tumors, diffuse histology, and metastatic spread. This trend raises concern for younger patients, especially in minority communities.
A predictive algorithm developed by Michelle Kang Kim, MD, PhD, highlights stark disparities. Black patients were over three times more likely to be at risk for non-cardia gastric cancer, while Asian patients had more than four times the risk. Other factors included male sex, tobacco use, and anemia. These findings suggest that targeted screening could be especially beneficial for high-risk groups.
“2021 marked the first year in which more gastric cancers were diagnosed at an early rather than an advanced stage,” Siddiqui noted. But the data also underscore the need for proactive strategies to reach vulnerable populations. As detection improves, so must efforts to ensure equity in diagnosis and care.
