Adenocarcinoma of the gastroesophageal junction in Japan: relevance of Siewert’s classification applied to 177 cases resected at a single institution

Abstract

A striking difference in the distribution of types of adenocarcinoma of the gastroesophageal junction was observed in Japan compared with previously reported western data. A subgroup of carcinoma of the proximal stomach identified as types II and III may not require proximal gastrectomy from the viewpoint of sufficient lymphadenectomy.
