The Lymph Node Ratio Is a Powerful Prognostic Factor of Node-Positive Colon Cancers Undergoing Potentially Curative Surgery
2009
Background
The number of harvested (LNs) and metastatic nodes (LNs+) represents the most significant factor to define postoperative treatment and prognosis in colon cancer. However, its assessment may be inadequate causing an incorrect cancer staging. The lymph node ratio (LNR: the ratio between metastatic and resected nodes) has shown prognostic significance in many tumors; however, its role in colon cancer is not clearly elucidated. This study investigated LNR as a prognostic factor in node-positive colon cancers.
