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.
- Under current guidelines, random endoscopic biopsies are taken in all 4 quadrants with a high resolution endoscope.
- It should be noted that those who presented with adenocarcinoma demonstrated no prior Barrett's esophagus in 80 - 90% of the time.
- Most dysplastic changes are found in white men that are older than 50 years of age.
- One study surmised that the only cost-effective strategy was once in a lifetime screening of 50+ year old, white men with GERD, followed by surveillance of those with dysplasia only.[1]
Squamous cell carcinoma screening
- Since 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.
- However, in China, esophageal cancer is the sixth most common cancer and the fourth most common cause of death from cancer.
- A screening program in a high risk population was put into effect where those with mild to moderate dysplasia are examined via endoscopy every 3 years, whilst those with severe dysplasia were screened once per year.
- The patients were concomitantly treated with monoclonal antibodies for the next three years, and the incidence decreased by 57%.
- These results demonstrated that the screening for esophageal squamous cell carcinoma is effective in the prevention of esophageal cancer.[2]
