Epigenetic array data of saliva samples in individiduals with esophageal cancer with controls. Epigenetic array data of saliva samples in individiduals with esophageal cancer with controls

We took saliva samples from 89 people with oesophageal cancer (plus 9 with high grade dysplasia, also labelled here as cancer) and 167 controls. We took replicate samples on 6 cancer samples and 4 controls to assess reproducibility. The cancer groups comprise people with invasive adenocarcinoma (61 and also 6 replicates), 28 people with intramucosal adenocarcinoma, 9 people with high-grade dysplasia arising in Barrett's esophagus, 52 patients with non-dysplastic Barrett's esophagus, 42 people with no positive diagnosis after endoscopy (ie no Barrett's, + 1 replicate), and 73 self-reported healthy volunteers (with 3 duplicates) Overall design: The principle design was a two group case-control study
