1 Extent of Lymphadenectomy Is Associated With Improved Overall Survival After Esophagectomy With or Without Induction Therapy  Pamela Samson, MD, MPHS, Varun Puri, MD, MSci, Stephen Broderick, MD, G. Alexander Patterson, MD, Bryan Meyers, MD, MPH, Traves Crabtree, MD  The Annals of Thoracic Surgery  Volume 103, Issue 2, Pages (February 2017) DOI: /j.athoracsur Copyright © 2017 The Society of Thoracic Surgeons Terms and Conditions

2 Fig 1 (A) Although no difference in overall survival (OS) was detected in patients who had ≥15 lymph nodes examined when undergoing upfront esophagectomy, a significant difference was seen for (B) patients who received induction therapy at this threshold. (LN = lymph node; NCCN = National Comprehensive Cancer Network.) The Annals of Thoracic Surgery  , DOI: ( /j.athoracsur ) Copyright © 2017 The Society of Thoracic Surgeons Terms and Conditions

3 Fig 2 Kaplan-Meier curve comparing patients undergoing upfront esophagectomy who had less than or greater than 25 lymph nodes sampled demonstrates a significant difference in survival.
