title: Oesophageal carcinoma--past and present studies.
abstract: Surgery is a crucial part of therapy of oesophageal cancer. The many trials which are described focus on variations in surgical technique. A trend is found that results are better with more extensive procedures. Local control evidently is improved, but an effect on survival is not yet sufficiently shown. Combinations of neoadjuvant radiotherapy and/or chemotherapy with surgery are effective by downstaging offering seemingly better survival in responding patients. Interpretation of trial data, however, is difficult because of the relatively small numbers in individual studies; the differences of the used treatment modalities make an overview approach less reasonable. Great attention should be given in the future trial work to better standardization (interpretation of definitions). Directives for optimal staging should be described in all study protocols.
