Neoadjuvant chemoradiotherapy improves survival in locally advanced adenocarcinoma of esophagogastric junction compared with neoadjuvant chemotherapy: a propensity score matching analysis.

Background: To analyze whether neoadjuvant chemoradiotherapy (nCRT) could improve the survival for patients with adenocarcinoma of the esophagogastric junction compared with neoadjuvant chemotherapy (nCT). Both neoadjuvant chemotherapy alone and chemoradiotherapy before surgery have been shown to improve overall long-term survival for patients with adenocarcinoma in the esophagus or esophagogastric junction compared to surgery alone. It remains controversial whether nCRT is superior to nCT.

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

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).

Patients And Methods: From March 2012 to December 2015, 170 patients with locally advanced (cT3-4NxM0) Siewert II and III AEG were treated with preoperative CRT or CT in Hebei Medical University Fourth Hospital, and 123 patients were included in this study to compare the effects of preoperative CRT with CT.
