Popis	Background: Local treatment improves the outcomes for oligometastatic disease (OMD, i.e. an intermediate state between locoregional and widespread disseminated disease). However, consensus about the definition, diagnosis and treatment of oligometastatic oesopha-gogastric cancer is lacking. The aim of this study was to develop a multidisciplinary European consensus statement on the definition, diagnosis and treatment of oligometastatic oesophago-gastric cancer. Methods: In total, 65 specialists in the multidisciplinary treatment for oesophagogastric cancer from 49 expert centres across 16 European countries were requested to participate in this Del-phi study. The consensus finding process consisted of a starting meeting, 2 online Delphi ques-tionnaire rounds and an online consensus meeting. Input for Delphi questionnaires consisted of (1) a systematic review on definitions of oligometastatic oesophagogastric cancer and (2) a discussion of real-life clinical cases by multidisciplinary teams. Experts were asked to score each statement on a 5-point Likert scale. The agreement was scored to be either absent/poor (<50%), fair (50%-75%) or consensus (>75%). Results: A total of 48 experts participated in the starting meeting, both Delphi rounds, and the consensus meeting (overall response rate: 71%). OMD was considered in patients with meta-static oesophagogastric cancer limited to 1 organ with <3 metastases or 1 extra-regional lymph node station (consensus). In addition, OMD was considered in patients without pro-gression at restaging after systemic therapy (consensus). For patients with synchronous or me-tachronous OMD with a disease-free interval <2 years, systemic therapy followed by restaging to consider local treatment was considered as treatment (consensus). For metachronous OMD with a disease-free interval >2 years, either upfront local treatment or systemic treatment fol-lowed by restaging was considered as treatment (fair agreement). Conclusion: The OMEC project has resulted in a multidisciplinary European consensus state -ment for the definition, diagnosis and treatment of oligometastatic oesophagogastric adeno-carcinoma and squamous cell cancer. This can be used to standardise inclusion criteria for future clinical trials. 2023 The Author(s). Published by Elsevier Ltd.
