Investigating the proximal limit of lymphadenectomy in patients with adenocarcinoma of the oesophagus in the mid‐thoracic region

The benefit of extended lymphadenectomy in patients with squamous cell carcinoma of the oesophagus is established, but there is little evidence to support this in patients with adenocarcinoma. The aim of this study was to investigate the extent of lymphatic spread of oesophageal adenocarcinomas, and particularly the proximal spread in tumours located in the mid thorax.
