Gastroesophageal cancers (including oesophageal, gastric and gastroesophageal junction lesions) are worldwide a leading cause of
death being relatively rare but highly aggressive. Frequency of the distal stomach cancer decreased, while the incidence of cancer of the
cardia and gastroesophageal junction (GEJ) has been rapidly rising.The GEJ anatomically separates the lower oesophagus from the
proximal part of the stomach, in the area where the squamous epithelium of oesophagus changes into the columnar epithelium of gastric cardia . In developed countries, the incidence of gastric cancer originating
from the cardia follows the distribution of oesophageal cancer, suggesting similar behaviours. Adenocarcinomas of the GEJ represent around 90% of all the GEJ
cancers. In general adenocarcinomas are considered at lower level of radiosensitivity than squamous cell carcinomas, but there are still
no clear evidences on this issue for the specific subset of GEJ tumours. In general, caucasian, male and over 40 years old patients (pts)
are the most affected subgroup. The predominant risk factors are:gastroesophageal reflux disease (GERD), Barrettâs oesophagus and
obesity, followed by tobacco and alcohol abuse.
