Rising Trends in Esophageal Adenocarcinoma: Implications for Early Detection and Multidisciplinary Management

Esophageal adenocarcinoma, the predominant form of esophageal cancer in Western countries, has seen a sharp rise in incidence, largely due to factors like obesity and gastroesophageal reflux disease. This review article highlights the urgent need for effective screening strategies to enable early diagnosis, which significantly improves patient outcomes. It provides a comprehensive update on the latest advancements in screening, diagnostic methods, and treatment approaches, underscoring the critical role of a multidisciplinary approach in managing early-stage esophageal adenocarcinoma.

Key Points:

• Esophageal adenocarcinoma is now more common than squamous cell carcinoma in the Western world, with a significant increase noted over the past decades.
• Despite advancements in treatment, the 5-year overall survival rate remains below 20% when diagnosed at later stages.
• Key risk factors include obesity, gastroesophageal reflux disease, male sex, age over 50, and family history of Barrett esophagus or esophageal adenocarcinoma.
• Current screening guidelines focus on high-risk groups but miss many cases, as nearly 90% of esophageal adenocarcinoma cases are diagnosed in patients not previously known to have Barrett esophagus.
• Endoscopic techniques, such as high-definition imaging and narrow-band imaging, have improved detection rates of Barrett esophagus, which is a precursor to esophageal adenocarcinoma.
• Novel screening tools like Cytosponge and swallowable balloon devices are showing promise in detecting early esophageal changes without the need for sedation and are currently under further research.
• Early esophageal adenocarcinoma can often be effectively managed with endoscopic resection, especially when tumors are detected while still confined to the mucosal layer.
• Surgical resection remains a crucial option for larger or more invasive tumors, with minimally invasive techniques reducing recovery time and improving postoperative outcomes.
• Ongoing research and clinical trials are essential to refine screening and treatment protocols, and to integrate emerging technologies into standard practice.

According to the American Cancer Society estimates, about 22,370 new esophageal cancer cases will be diagnosed (17,690 in men and 4,680 in women) in 2024, with approximately 16,130 deaths from the disease (12,880 in men and 3,250 in women).
