Kurzfassung

BACKGROUND Adenocarcinoma of the esophagogastric junction (AEG) is a rare but rising tumor entity in the Western world. Treatment is complex, as multimodality is key to optimal results. However, trials solely including AEG are rare, and the question if neoadjuvant radiochemotherapy (NRCT) or neoadjuvant/perioperative chemotherapy (NACT) is superior remains unanswered. PATIENTS AND METHODS Patients with AEG I-III treated between October 2010 and August 2019 at the Ordensklinikum Linz or the Kepler University Hospital were identified either from a monitored tumor registry or by chart review. Time-to-event data were analyzed by Kaplan-Meier product limit estimation. The Kruskal-Wallis test and Fisher's exact test were used for comparing continuous and categorical data, respectively. RESULTS A total of 85 patients (median age 63 years; median Charlson Comorbidity Index 3; 98.8% ECOG PS 0-1) were analyzed. Of these, 52 patients received NRCT (81% CROSS protocol) and 33 NACT (65% EOX and 35% FLOT protocol). There was a significantly higher pathological complete response rate in the NRCT group (30 vs. 12%; p = 0.010); distant relapse rates were higher in the NRCT group and local relapse rates were higher in the NACT group (both not significant). These differences, however, did not translate into a different disease-free survival (20 months; 95% CI: 13-34) or overall survival (44 months; 95% CI: 33-NA). Patients >65 years old had the same advantage from treatment as patients <65 years of age. CONCLUSIONS Although treatment of AEG is complex, the progress documented over the last centuries can be reproduced in our real-life setting. Data regarding the superiority of either type of neoadjuvant/perioperative treatment are sparse. We assume no difference between EOX-based NACT and NRCT.
