Impact of the Number and Extent of Positive Lymph Nodes in 200 Patients with Thoracic Esophageal Squamous Cell Carcinoma after Three‐field Lymph Node Dissection

Abstract

Together, number and extent of positive lymph nodes can be considered an independent predictor of a high risk of recurrence. Although cervical lymphatic spreading was risk factor for worse survival, patients with upper tumors may have survival benefit after cervical lymph node dissection.
