Oesophageal cancer usually originates in the lining of the oesophagus and can develop in the upper, middle, or lower section of the organ (1).
- epithelial tumours are responsible for more than 95% of cases oesophageal carcinomas
- non epithelial cell carcinomas are rare e.g. - metastatic tumour, lymphomas, sarcomas (2)
Epithelial tumour has two main subtypes:
- oesophageal squamous-cell carcinoma (SCC)
- is the most common oesophageal cancer subtype - responsible for 87% of all cases of oesophageal cancer in 2012
- usually affects the upper two thirds of the oesophagus
- occurs most commonly in the middle third of esophagus
- males and females are affected equally
- oesophageal adenocarcinoma
- more common in the lower third of the oesophagus
- three to four times as common in men as it is in women (3,4,5)
Tumours tend to arise in areas of partial narrowing, i.e. at the pharyngo-oesophageal junction (40%); the junction of the upper and middle third (40%); and where the oesophagus passes through the diaphragm (20%) (6).
- there are around 13,000 new cases of oesophago-gastric cancer diagnosed
in England each year
- mortality rates are high, with over 10,000 deaths annually, and over the last 30 years the incidence of these cancers has continued to increase
