Early oesophageal cancer. Does it exist? Why we cannot find it?

Area of Science:

• Gastroenterology
• Oncology
• Surgical Oncology

Background:

• Surgical outcomes for esophageal cancer remain suboptimal.
• Early detection of esophageal cancer is crucial for improving patient prognosis.
• Targeted screening programs can identify asymptomatic individuals with early-stage disease.

Purpose of the Study:

• To evaluate the effectiveness of endoscopic screening with Lugol staining for early detection of esophageal cancer.
• To assess the feasibility of implementing a population screening program in well-defined patient groups.
• To improve diagnostic sensitivity for identifying early esophageal malignancies.

Main Methods:

• Endoscopic screening program for patients with Barrett's esophagus or history of lye ingestion.
• Utilized Lugol solution for enhanced visualization of esophageal mucous membrane during endoscopy.
• Follow-up period of five years to identify early cancer cases.
• Endoscopic ultrasonography employed for staging confirmed esophageal cancer cases.

Main Results:

• Four cases of early esophageal cancer were detected during the five-year follow-up.
• Two of the detected cancers were confined to the mucous membrane, indicating very early-stage disease.
• All identified early-stage cancers were treated surgically with positive outcomes.
• Preliminary data suggest the efficacy of population-based screening in selected high-risk groups.

Conclusions:

• Endoscopic screening with Lugol staining is a promising method for detecting early esophageal cancer in high-risk populations.
• The study supports the implementation of targeted screening programs for specific patient groups.
• Early detection and surgical intervention significantly improve outcomes for esophageal cancer.
