Comparison of preoperative concurrent chemoradiotherapy with chemotherapy alone in patients with locally advanced siewert II and III adenocarcinoma of the esophagogastric junction

摘要

Purpose: Preoperative therapy improves overall survival (OS) after surgery in patients with adenocarcinoma of the esophagogastric junction (AEG). We aimed to retrospectively analyze whether preoperative chemoradiotherapy (CRT) could improve the prognosis of patients with locally advanced Siewert II and III AEG comparing with preoperative chemotherapy alone (CT).
