Survival in Advanced Esophagogastric Adenocarcinoma Improves With Use of Multiple Lines of Therapy: Results From an Analysis of More Than 500 Patients

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.
