Extent of Lymphadenectomy and Long-term Survival in Esophageal Cancer

To examine the hypothesis that survival in esophageal cancer increases with more removed lymph nodes during esophagectomy up to a plateau, after which it levels out or even decreases with further lymphadenec-tomy.There is uncertainty regarding the ideal extent of lymphadenectomy during esophagectomy to optimize long-term survival in esophageal cancer.This population-based cohort study included almost every patient who underwent esophagectomy for...
