The number of recovered lymph nodes (LNs) is associated with the prognosis of patients with esophageal squamous cell carcinoma (ESCC) undergoing surgical resection. A relationship between negative LN count and patient outcome has been demonstrated in gastrointestinal cancers, including colon and gastric cancers. However, little is known about the prognostic significance of negative LN counts in ESCC. ⋯ A negative LN count was associated with improved survival in patients with curatively resected ESCC.
