Cancers involving the esophagogastric junction (EGJ) whose epicenter is within the proximal 2 cm of the cardia (Siewert types I/II) are therefore to be staged as esophageal. Cancers whose epicenter is more than 2 cm distal from the EGJ will be staged using the Stomach Cancer TNM and Stage even if the EGJ is involved.
