Objective:

To investigate global and regional epidemiological trends of esophageal, stomach, and colorectal cancers among adolescents and young adults (AYA), emphasizing their unique risk factors and the implications for public health.

Approach:

Key Findings:

• Colorectal cancers are the third most prevalent cancer by incidence and second by death globally, highlighting the need for targeted interventions.
• In 2021, there were 70,201 new cases of colorectal cancer in AYA, resulting in 26,222 deaths, underscoring the urgency of addressing this issue.
• The burden of digestive tract cancers has increased over the past three decades, correlating with socioeconomic development, indicating a need for tailored public health strategies.

Interpretation:

The increasing incidence of early-onset digestive tract cancers in AYA highlights the need for targeted prevention and control strategies, especially in high HDI regions, such as implementing screening programs and health education.

Limitations:

• Potential data sparsity in low-SDI regions may affect the accuracy of findings, and biases in data collection methods could also influence results.
• The study relies on existing data and modeling, which may not capture all nuances of cancer epidemiology.

Conclusion:

Understanding the epidemiological characteristics of digestive tract cancers in AYA is crucial for public health strategies and resource allocation, necessitating a proactive approach to address these emerging trends.
