Overview
Esophageal cancer may be classified into squamous cell carcinoma or adenocarcinoma based on histology.
Classification
Esophageal cancers are typically carcinomas, which arise from the epithelium, or surface lining of the esophagus. Most esophageal cancers fall into one of two classes according to their histology. [1]
- Squamous cell carcinoma
- Esophageal squamous cell carcinoma are similar to head and neck cancer in their appearance and are associated with smoking and alcohol consumption.
- Adenocarcinoma
- Esophageal adenocarcinomas make up more than 70% of esophageal cancers.
- They are often associated with a history of gastroesophageal reflux disease and Barrett's esophagus.
