The oesophagus, also known as the food pipe is the tube that allows food to travel from the mouth to the stomach. The lower part of the oesophagus that connects to the stomach is called the gastroesophageal junction. The gastroesophageal junction has a ring of muscles which control the movement of food from the esophagus into the stomach, called the oesophageal sphincter. The gastroesophageal junction lies just below the diaphragm, beneath the lungs. Cancer that starts in the glandular cells of the gastroesophageal junction is known as gastroesophageal junction adenocarcinoma. Any cancer that starts in the glandular cells is termed as an adenocarcinoma. Gastroesophageal junction adenocarcinoma is considered to be a type of oesophageal cancer. Oesophageal cancer is prevalent to an undesirable point in India, being the 4th common cause of cancer related deaths in India. This statistic is thought to be due to tobacco consumption and poor nutrition in certain regions of India.

Symptoms
Unfortunately, most oesophageal cancers, including gastroesophageal junction adenocarcinoma, do not present any symptoms until they have grown large and spread to an advanced stage. When they do, they cause symptoms like:
• Difficulty swallowing, known as dysphagia
• Increased production of saliva
• Hoarseness
• Unintentional weight loss
• Hoarseness
• Painful swallowing or heartburn like pain
• Nausea and vomiting
• Chronic cough or hiccups
• Black stools from gastrointestinal bleeding
• Anaemia
• Bone pain

Causes and Risk Factors
The cause of gastrointestinal junction adenocarcinoma, like most cancers, is not fully understood. DNA from the oesophageal cancer cells show changes in genes, but what causes these genetic changes (mutations) is not fully understood. There are, however, certain risk factors which are known to increase the risk of oesophageal cancer. These include:
• Being male. Males are four times more susceptible to oesophageal cancer than females.
• Increasing age. 85% of patients are above 55.
• Gastroesophageal reflux disease (GERD) or Barrett’s Oesophagus, which cause changes in the lining of the oesophagus.
• Tobacco use (Chewing or smoking)
• Alcohol use
Obesity
Diet. A diet rich in fruits and vegetables decreases the risk, while eating processed meat increases the risk.
• Achalasia, which is a disorder of movement of oesophagus.
Gastroesophageal junction adenocarcinoma is usually diagnosed by a gastroenterologist, a specialist in gastroenterology. Treatment is usually done by a gastroenterological oncologist.
