BACKGROUND: Although progress has been made in the molecular stratification of esophagogastric adenocarcinoma, the outlook for advanced disease remains poor. The present evaluation of over 500 patients treated at a single European high-volume tertiary center during a 6-year period gives important information on current and developing "real-world" treatment patterns and outcomes. RESULTS: The overall survival for the whole cohort was 11.5 months, with a range of treatments used in first-, second-, and third-line settings. Treatment with sequential lines of therapy was associated with better outcomes, although only 39% and 14% of patients subsequently received treatment in the second- and third-line setting, respectively. Treatment within a therapeutic clinical trial was associated with significantly improved survival. CONCLUSION: At present, a substantial proportion of patients with advanced esophagogastric adenocarcinoma will not proceed beyond first-line therapy, and for this group refinement of initial systemic therapies are required to improve outcomes. Although a number of established first- and second-line treatment options are now available, the therapeutic landscape of the disease continues to change, most notably in the application of immunotherapy and increasing interest in establishing evidence-based interventions in the third-line setting and beyond. A small but growing proportion of patients will benefit from sequential treatment approaches incorporating multiple lines of therapy, and improved selection of such patients will be a key challenge for clinicians moving forwards. Data such as these provide an overview of current treatment patterns and outcomes which can be used to inform planning of future research effectively within existing treatment frameworks.
