Headline: HPSA Testing and FIT: New Insights into Gastric Cancer Screening
In a groundbreaking community-based clinical trial, researchers have explored the effectiveness of adding Helicobacter pylori stool antigen (HPSA) testing to a fecal immunochemical test (FIT) for colon cancer screening. While the addition did not show a significant reduction in gastric cancer incidence or mortality when compared to FIT alone, adjustments for confounding factors indicated a noteworthy decrease in the incidence of gastric cancer among those screened with HPSA. With gastric cancer accounting for a significant number of cancer-related deaths globally, these findings carry profound implications for public health interventions.
A Closer Look at Gastric Cancer
Gastric cancer remains a leading cause of cancer mortality worldwide, with chronic infections from Helicobacter pylori implicated in at least 80% of cases. Given the high stakes of early detection and management, this study, involving 240,000 adults averaging 58.1 years in age, sought to clarify whether integrating HPSA testing into continued FIT screenings could offer better outcomes.
Study Overview and Methodology
Conducted by Yi-Chia Lee, MD, PhD, from the Department of Internal Medicine at National Taiwan University, the trial randomly assigned participants to two groups: one that received HPSA testing plus FIT and another that was invited to partake in FIT alone. The screening invitations were sent out via phone calls, resulting in 63,508 participants receiving HPSA tests alongside FIT, compared to 88,995 participants receiving only FIT.
By focusing on primary outcomes—incidence rates and mortality rates of gastric cancer—the study monitored participants over a median period of 5.7 years for the HPSA testing plus FIT group and 5.4 years for the FIT-only group.
Findings and Key Takeaways
The trial yielded some promising results despite its challenges. Participation rates surged in the HPSA testing group at 49.6%, considerably surpassing the FIT-only group’s 35.7%. Remarkably, among the 12,142 participants with positive HPSA results, 71.4% received antibiotic therapy, and a remarkable 91.9% achieved successful eradication of H. pylori after treatment.
While the overall rate of gastric cancer incidence remained statistically similar between the two groups (0.032% for HPSA plus FIT versus 0.037% for FIT alone), after adjusting for screening participation and various other factors, a relative risk reduction emerged for the HPSA plus FIT group (0.79; P = .04). However, mortality rates from gastric cancer showed no significant difference (0.015% vs. 0.013%).
Expert Insights
Dr. M. Constanza Camargo from the Division of Cancer Epidemiology and Prevention at the National Cancer Institute reflected on the trial’s significance, stating, “This innovative trial conveys valuable insights for the primary prevention of gastric cancer, with potential application to diverse settings. Notably, the results show that the implementation of H. pylori test-and-treat strategies is indeed possible using screening platforms already in place.” This observation underscores the potential for health systems to integrate HPSA testing into existing preventive care initiatives, representing an opportunity to enhance early diagnosis and treatment of gastric cancer.
Implications for Public Health
This study not only underscores the intricate relationship between H. pylori and gastric cancer but also suggests a practical pathway forward for improving screening strategies. By utilizing existing FIT screening programs and adding HPSA testing, healthcare practitioners could reach more patients, potentially lowering the rate of gastric cancer diagnosis later in the disease trajectory—an approach that could ultimately save lives.
Overcoming the challenges of implementing widespread H. pylori screening takes collaboration across various healthcare sectors. This study lays a foundation for future research aimed at understanding the broader impact of such strategies on population health.
Engaging with the Future of Cancer Screening
As healthcare continues to advance through technology and innovative approaches, the need for effective cancer screening solutions remains critical. The findings from this trial prompt a deeper conversation about integrating test-and-treat strategies within screening frameworks. By stimulating dialogue among public health professionals, researchers, and patients, these advancements may lead to improved strategies that prioritize common health challenges.

How might the results of this study influence public health strategies for the prevention and management of gastric cancer?
Welcome to World Today News! Today, we are joined by two esteemed guests to discuss a groundbreaking clinical trial exploring the effectiveness of adding Helicobacter pylori stool antigen (HPSA) testing to fecal immunochemical testing (FIT) for colon cancer screening. This study has important implications for the detection and management of gastric cancer, which is responsible for a significant number of cancer-related deaths globally.
First, let’s start with Dr. Yi-Chia Lee, the lead author of the study, from the Department of Internal Medicine at National Taiwan University. Dr. Lee, can you provide us with a brief overview of the study and its main findings?
Dr. Yi-Chia Lee: Of course. Our study involved a large population-based, randomized clinical trial that compared the effectiveness of adding HPSA testing to FIT with FIT alone in reducing the incidence and mortality of gastric cancer. We had two groups: one that received HPSA testing plus FIT and another that was invited to partake in FIT alone. we observed a similar incidence of gastric cancer between the two groups, but after adjusting for screening participation and various other factors, we noticed a relative risk reduction of 0.79 in the HPSA plus FIT group. However, mortality rates from gastric cancer showed no significant difference between the two groups.
This is a promising start, but there are still ongoing discussions about whether these findings warrant the integration of HPSA testing into mainstream screening programs. Dr. M. Constanza Camargo, from the Division of Cancer Epidemiology and Prevention at the National Cancer Institute, can you share your thoughts on the implications of these findings for public health?
Dr. M. Constanza Camargo: Absolutely. I think this innovative trial conveys valuable insights for the primary prevention of gastric cancer, with potential application to diverse settings. It shows us that the implementation of HPSA test-and-treat strategies is indeed possible using screening platforms already in place. This underscores the potential for health systems to integrate HPSA testing into existing preventive care initiatives, ultimately improving early diagnosis and treatment of g
