We report the development of a multicentre prospective database for gastro-oesophageal cancer surgery. The ASCOT project aims to collect detailed prospective data on co-morbidity, surgery, stage and outcome in a large cohort of patients from a wide variety of hospitals in the UK. We describe the rationale for the initiative, the process of defining the dataset, the database software and structure, the system for data recording and retrieval and the operating rules of the ASCOT co-operative group. Thirty Trusts are currently submitting data, and the first 1000 cases have now been entered. A first annual report has been produced, showing anonymized comparative figures for patient characteristics and outcomes of interest, and a second is due shortly. The collection of detailed comparable data, including co-morbidity evaluation, on a large scale is likely to prove valuable for unit specialist accreditation, surgeon re-validation, audit and research.
