Optimal Proximal Margin Length Improves Prognosis in Adenocarcinoma of Gastroesophageal Junction

Study finds proximal margin length ≥1.2 cm linked to improved outcomes in Siewert II/III adenocarcinoma of esophagogastric junction, lowering risk of disease progression. This offers valuable guidance for surgical decision-making and enhances patient outcomes, particularly for subgroups with specific tumor characteristics. These findings emphasize the importance of optimal proximal margin length in surgical approaches for adenocarcinoma of the gastroesophageal junction.
