Adjuvant chemoradiation in gastric cancer: long-term outcomes and prognostic factors from a single institution.

Background: Adjuvant chemoradiotherapy (CRT) improves relapse-free (RFS) and overall survival (OS) in patients with resected gastric cancer. However, difficulties in standardizing an optimal surgical approach and a perceived higher toxicity compared with the perioperative approach have limited its widespread application in Europe. The aim of our study was to assess toxicity and long-term outcomes of adjuvant CRT at our institution.
