Introduction.

Proper diagnosis of gastroesophageal junction tumors is essential for the treatment of these patients. The classification proposed by Siewert-Stein defines its own characteristics, risk factors and surgical strategies according to the location. This study describes the characteristics of patients with adenocarcinoma of the esophagogastric junction treated at our institution.

Methods.

Retrospective, descriptive, longitudinal study, which includes patients diagnosed with adenocarcinoma of the esophagogastric junction who underwent surgery at the National Cancer Institute in Bogotá, Colombia, between January 2012 and May 2017.

Results.

Fifty-nine patients (84.7% men) were operated on, with a mean age of 62.5 years. In their order of frequency, the tumors were type II (57.6%), type III (30.7%) and type I (11.9%). 74.6% received neoadjuvant therapy and total gastrectomy was performed in 73% of the cases. The moderate diagnostic concordance with the Kappa index was 0.56, differing from the endoscopic one in 33.9%. 10.2% of the patients presented some type of intraoperative complication. Three-year survival in type II tumors was 89.6% and 100% in those with complete pathologic response.

Conclusion.

The use of different strategies is necessary for an adequate diagnostic process in tumors of the esophagogastric junction. In this series, Siewert II patients, those who received neoadjuvant therapy, and those who obtained a complete pathological response had a better three-year survival.
