Author contributions: Paterson S and Stanley AJ conceived this manuscript; Smith L, Bisland J, López González E and Harrington C collected data; Harrington C wrote the paper, with input from all co-authors who approved the final submission.
Institutional review board statement: After discussion with the local Ethics Service, they considered this retrospective project to be an audit rather than a research project, therefore ethical approval was not required.
Informed consent statement: As this retrospective study was accepted to be an audit project, with anonymised data and no intervention for any patient, informed consent from patients was not required.
Conflict-of-interest statement: There are no conflicts of interest for any of the authors.
Data sharing statement: The raw data is available from Harrington C at chrisharrington@nhs.net. Consent has not been obtained for sharing of this data but all data have been anonymised and the risk of identification is therefore low.

Core Tip

Core tip: We have found that positron emission tomography-computed tomography (PET-CT) in the setting of upper gastrointestinal cancer has a high sensitivity and negative predictive value, but has poor specificity and positive predictive value for the detection of malignant mediastinal lymph nodes. This could lead to many patients being over-staged by PET-CT alone. The use of endoscopic ultrasound-guided fine-needle aspiration of mediastinal nodes results in more patients being offered radical therapy.
