IARC Report: Screen-and-Treat Strategies for Gastric Cancer Prevention Highlighted in *New England Journal of Medicine*

A new report published in the New England Journal of Medicine summarizes recommendations from an international working group convened by the International Agency for Research on Cancer (IARC) of the World Health Organization (WHO). The report focuses on implementing population-based strategies to screen for and treat Helicobacter pylori (H. Pylori) infection as a means of preventing gastric cancer. IARC Press Release

H. Pylori and Gastric Cancer: A Preventable Link

Helicobacter pylori is a bacterium that infects the stomach and is a major cause of chronic gastritis, peptic ulcers, and gastric cancer. Gastric cancer is the fifth most common cancer worldwide, and H. Pylori infection is a significant risk factor, particularly in certain regions. Screening and treating H. Pylori infection can significantly reduce the incidence of this cancer.

IARC Working Group Recommendations

The IARC working group evaluated evidence and developed guidance on implementing screen-and-treat programs. The article, published online March 11, 2026, details these recommendations. NEJM Abstract The report, titled “Helicobacter pylori screen-and-treat programs for gastric cancer prevention – IARC Working Group Report”, provides a comprehensive overview of the strategies.

Key Considerations for Implementation

Effective implementation of H. Pylori screen-and-treat programs requires careful consideration of several factors, including:

• Target Population: Identifying populations with a high prevalence of H. Pylori infection and a high risk of gastric cancer.
• Screening Methods: Utilizing appropriate and cost-effective screening methods to detect H. Pylori infection.
• Treatment Regimens: Employing effective treatment regimens to eradicate H. Pylori infection.
• Program Monitoring and Evaluation: Continuously monitoring and evaluating the program’s effectiveness and making adjustments as needed.
