Gene breakthrough on oesophageal cancer

A team of experts in the US unravelled the genetic code of tumour cells from 149 patients, which they compared to healthy cells to identify a mutation signature for oesophageal adenocarcinoma (EAC).

This type of cancer has a five-year survival rate of only 15–20%.

EAC often originates from Barrett's oesophagus, which in turn is caused by chronic acid reflux.

Incidence of the cancer has increased by 600% over the last 30 years – particularly in Western countries, according to the study.
