The esophagus is the tube that carries food from the mouth to the stomach. Esophagectomy (with or without partial stomach resection) is mainly performed on patients with malignant tumors. The two most frequent malignancies are squamous cell carcinoma and adenocarcinoma.
There is a known link between frequent consumption of very hot beverages and the development of this disease. The incidence of squamous cell cancer is almost 100 times higher among individuals who have suffered chemical burns to the esophagus. An increased risk is also noted in patients with achalasia — a benign esophageal condition characterized by impaired emptying and peristalsis.
Unlike squamous cell carcinoma, esophageal adenocarcinoma is more common in Western countries. In recent decades, the incidence of this form of esophageal cancer in Israel and globally has been rising steadily compared to other types.
Adenocarcinoma frequently occurs in patients with chronic gastroesophageal reflux (GERD), where stomach contents move backward into the esophagus. This can lead to a condition known as Barrett’s esophagus.
Barrett’s esophagus is a state where abnormal (precancerous) cells develop in the lower lining of the esophagus. These cells may undergo dysplastic changes, which are not yet cancerous but can progress to esophageal cancer in approximately 1 out of 100 patients over time.
