Objective: Surveillance, Epidemiology and End Results (SEER) data indicate that number of lymph nodes removed impacts survival in gastric cancer. Our aim was to study this relationship in esophageal cancer. Methods: The study population included 2303 esophageal cancer patients (1381 adenocarcinoma, 922 squamous) from 9 international centers that had R0 esophagectomy prior to 2002 and were followed at regular intervals for 5 years or until death. Patients treated with neoadjuvant or adjuvant therapy were excluded.
