ARTICLE HIGHLIGHTS
Research background
The incidence of oesophageal adenocarcinoma (OAC) is increasing exponentially annually as a consequence of obesity. The current therapeutics remain chemo(radio)therapy with mixed responses. The purpose of this work is to determine baseline damage associated molecular pattern (DAMP) expression in OAC patients as well as the effects of chemo(radio)therapy on DAMP expression.
Research motivation
To identify new therapeutic strategies in OAC.
Research objectives
This study aims to interrogate OAC DAMP expression.
Research methods
Patient tumour and serum samples were assessed for DAMP expression as well as tumour cell lines to mimic the tumour microenvironment.
Research results
Conventional therapies increase DAMP expression.
Research conclusions
OAC is an immunogenic cancer and must be exploited to harness immune mediated anti tumour responses.
Research perspectives
This is the first study of its kind in esophageal cancer looking at the baseline expression of DAMPs which is viewed as a surrogate marker of immunogenicity. Furthermore, it looks at the effects of conventional therapies on the immunogenicity of OAC.
