Prognostic Impact of Lymphnode Metastasis Mode in Patients with Esophageal Squamous Cell Carcinoma

摘要

The prognostic impact by lymphnode metastasis classifications in patients with esophageal squamous cell carcinoma was examined in the present study. Of 195 patients underwent esophagectomy 94 had lymphnode metastasis pathologically and detailed analysis was performed using following positive-lymphnode classification, pN of TNM classification, the number of positive lymphnode or mode of positive lymphnode station. Lymphnode metastasis was a good prognostic predictor in our series (p=0.0001). Also each classification, pN (p=0.0001), number of positive node (p=0.0025), mode of positive station (p=0.0424), had a significant prognostic impact on lymphnode metastasis positive patients. Detailed analysis of lymphnode metastasis has a utility as prognostic predictor in patients with esophageal squamous cell carcinoma.
