Author contributions: Noble F and Nolan L contributed equally to this study; Noble F collected the data and analysed it; Noble F, Nolan L, Underwood TJ and Bateman AR wrote the manuscript; Bateman AC scored the initial patients for pathological regression before this was adopted by the multidisciplinary team; Underwood TJ and Bateman AR had overall responsibility for the scientific content of the manuscript; all authors conceived jointly the idea for the manuscript and contributed to the analysis and reviewed and edited the text.
Supported by A clinical research training fellowship from Cancer Research UK to Noble F; A Medical Research Council (United Kingdom) clinician scientist fellowship to Underwood TJ

Core Tip
Core tip: Predictive markers of benefit from neoadjuvant chemotherapy (NAC) in esophageal adenocarcinoma are urgently required to provide a “personalised medicine” approach: directing treatment to those most likely to benefit. Before prospective studies can be initiated, retrospective series need to be interrogated to identify likely candidate markers of a positive response. In defining a positive response attention needs to be given to both response in the primary tumour and in the lymph nodes, as a previously unidentified group of patients who appear to have a poor tumoural response to NAC (tumour regression grade 3-5) do benefit from combination therapy by nodal downstaging.
