Improving esophageal cancer screening across the globe: Translating knowledge into action

Area of Science:

• Oncology
• Gastroenterology
• Public Health

Background:

• Esophageal cancer (EC) is a major global health issue, being the 8th most common cancer and 6th leading cause of cancer death.
• Esophageal adenocarcinoma (EAC) and esophageal squamous cell carcinoma (ESCC) are the primary types, with poor survival rates, especially in advanced stages (<20% 5-year survival).
• Current endoscopic screening is limited by invasiveness, cost, and low uptake, leading to delayed diagnoses.

Purpose of the Study:

• To highlight the need for improved, population-level screening techniques for esophageal cancer.
• To emphasize the potential of minimally invasive, cost-effective non-endoscopic technologies for early detection.
• To advocate for the implementation of these technologies in primary care for high-risk groups.

Main Methods:

• Review of current challenges in esophageal cancer screening.
• Discussion of advanced endoscopic techniques and their limitations.
• Exploration of non-endoscopic technologies for population-based screening.

Main Results:

• Advanced endoscopic techniques show promise but face barriers to widespread adoption.
• Low screening rates contribute to late diagnosis and poor patient outcomes.
• Non-endoscopic, minimally invasive methods are identified as a critical need.

Conclusions:

• There is a significant need for accessible, non-endoscopic screening tools for esophageal cancer.
• Implementing these tools in primary care settings can improve early detection rates.
• Early detection and surveillance offer hope for reducing EC morbidity and mortality.
