Pathology - Esophageal Adenocarcinoma
Esophageal Adenocarcinoma is a type of cancer that affects the esophagus.
The extensive historical record of GERD substantiates this diagnosis. Individuals suffering from GERD commonly have a reduction in the tone of the lower esophageal sphincter, which results in the backflow of stomach contents into the esophagus. Over time, the esophagus undergoes metaplastic changes at the gastroesophageal junction due to exposure to acidic gastric secretions. This results in the transformation of the typical squamous cells of the esophageal tissue into columnar cells, which are characteristic of gastric epithelium, in order to adapt to the gastric acid exposure. This alteration can be observed by endoscopy and is referred to as Barrett's esophagus. It serves as a precursor to the development of esophageal cancer. Administration of drugs such as PPIs and H2 blockers can lead to a reduction in the acidic stimuli, which in turn can result in the reversal of metaplasia. However, persistent reflux is likely to lead to the development of esophageal cancer, which would require surgical intervention for removal. Radiation and chemotherapy may be considered as treatment options, depending on the cancer's stage.
