IMaC - Immune Pathways in Oesophagogastric Cancer

Sponsor: Royal Marsden NHS Foundation Trust

Summary

The number of cases of oesophagogastric cancer is increasing every year. Currently, only 39% of patients with oesophageal cancer can have potentially curative treatment by the time they are diagnosed. This is because it typically presents late, and it is only when patients start to develop symptoms of advanced disease such as difficulty swallowing and weight loss, that they seek medical attention. There are approximately 9300 new cases of oesophageal cancer in the UK each year and at 17%, it has the 5th poorest 5-year survival of all cancers in the UK. It is diagnosed by carrying out a camera test called a gastroscopy which allows a biopsy of the cancer to be taken. This is an invasive procedure, and unlike for other types of cancer, such as bowel cancer, there is no test to risk-stratify patients at an earlier stage. Risk-stratification enables patients more likely to develop oesophagogastric cancer to be identified, which allows them to have more focused follow-up. This can potentially enable cancer to be diagnosed earlier, before the disease becomes more advanced, allowing patients to have potentially curative treatment. Scientific research has identified that the healthy bacteria in the oesophagus and stomach changes as oesophagogastric cancer develops. The investigators want to see if similar changes can be identified in the healthy bacteria in the mouth which could be indicative of cancer developing in the oesophagus or stomach. The investigators then hope to use this information to develop a non-invasive risk-stratification tool that can be used to diagnose oesophagogastric cancer earlier and thereby enable more patients to be cured.
