The Siewert classification of adenocarcinoma of the esophagogastric junction (EGJ) defines Type I, II, and III based on the relationship of the tumor center to the EGJ. Siewert Type II tumors originate within what distance from the EGJ?

• A 1 cm above to 2 cm below the EGJ
• B 2 cm above to 2 cm below the EGJ ✓
• C 5 cm above the EGJ to the EGJ
• D 2 cm to 5 cm below the EGJ

Explanation

Siewert classification: Type I — adenocarcinoma of the distal esophagus, epicenter 1–5 cm above the EGJ (usually arising in Barrett's esophagus); Type II — true cardia carcinoma, epicenter 1 cm above to 2 cm below the EGJ; Type III — subcardial gastric carcinoma, epicenter 2–5 cm below the EGJ infiltrating the EGJ from below. Siewert Type II is the 'true junction' cancer with disputed optimal surgical approach (transhiatal vs. transthoracic esophagogastrectomy vs. total gastrectomy).
