[Resectable adenocarcinoma of the oesophagogastric junction care: which perioperative treatment?].
Adenocarcinoma of the oesophagogastric junction has an ominous prognosis. Until now, oesophageal adenocarcima care was close to the squamous cell cancer one whereas adenocarcinoma of the cardia was mixed with gastric cancers. Results from randomised studies mixed them without making distinctions. Nevertheless, context, natural history and clinical outcome differ. Five-year survival rate is around 40 %, all stages included. Results from several phase-III studies or meta-analysis allowed to define three therapeutic strategies applicable to adenocarcinoma of the oesophagus and the oesophagogastric junction. In Europe, in the case of a resectable tumour, preoperative chemotherapy became a standard treatment since results from the Magic trial. In the United States, post-operative radiochemotherapy according to the "Macdonald" scheme is used in case of a resected tumour with a R0 surgery. Actually, modern techniques of irradiation could reduce the rate of gastro-intestinal toxicities. The survival benefit from preoperative radiochemotherapy is still very controversial with high rates of postoperative morbidity and mortality. We have performed a review of the literature with a methodological analysis of data with a high level of evidence in order to advise perioperative treatment guidelines for patients with a resectable adenocarcinoma of the lower oesophagus or gastro-oesophageal junction. Results from pre- or postoperative strategies and the role of radiotherapy will need to be analysed in the future through a randomised study.
