Overview
Screening may be effective in reducing the incidence of esophageal cancer, especially in Barrett's esophagus-associated adenocarcinoma, however, not very cost effective.
Screening
Adenocarcinoma screening
- The predominant type of esophageal cancer in the United States is adenocarcinoma.
- Screening is recommended for white men over the age of 50 years.[1]
- Screening should include random endoscopic biopsies taken in all 4 quadrants with a high resolution endoscope once in a lifetime.
- It should also be noted that those who present with adenocarcinoma demonstrate no prior Barrett's esophagus in 80 - 90% of the time.
Squamous cell carcinoma screening
Squamous cell carcinoma of the esophagus is more prevalent in underdeveloped countries; there is no reliable data to suggest that screening programs are effective when implemented.
- A screening program in a high risk population was established in Hishun village,China.
- Those with mild to moderate dysplasia were examined via endoscopy every 3 years, whilst those with severe dysplasia were screened once per year.
- All the patients were concomitantly treated with monoclonal antibodies for the next three years.
- At the end of three year monoclonal antibody trial, the incidence rate of esophageal squamous cell carcinoma had decreased by 57% in comparison to previous incidence rates.
- These results demonstrated that screening for dysplastic changes in the esophagus is effective in the prevention of esophageal squamous cell carcinoma.[2]
