The incidence of oesophageal adenocarcinoma (OAC) has risen six-fold in western countries over the last forty years but survival rates have only marginally improved. Hyperactivation of the PI3K-AKT-mTOR pathway is a common occurrence in OAC, driving cell survival, proliferation and resistance to chemotherapeutic agents. Inhibition of AKT has been explored as a treatment strategy with limited success and current inhibitors have failed to progress through clinical trials.

Alongside this trend, an increase in incidence of early-onset OAC, defined as OAC in adults aged under 50 years, has been observed. It is unclear whether survival outcomes for early-onset OAC patients differ from older age groups.

We investigated the predictive role and underlying biology of a 44-gene DNA damage immune response (DDIR) signature in patients with advanced GOA.
Materials And Methods: Transcriptional profiling was carried out on pretreatment tissue from 252 GOA patients treated with platinum-based chemotherapy (three dose levels) within the randomized phase III GO2 trial.
