Lymph node ratio is an independent prognostic factor after resection of periampullary malignancies: data from a tertiary referral center in the middle East.
The prognostic impact of nodal involvement in resected pancreatic carcinoma and biliary malignancy has been relatively well established. It has been suggested that lymph node ratio (LNR) may be a more informative way of stratifying patients with node positive disease. Our retrospective review aimed to investigate the significance of such variables and test for independent prognostic factors for survival. ⋯ After pancreaticodudonectomy for adenocarcinoma of the pancreas and biliary malignancies, ratio-based lymph node staging is an independent and powerful prognostic factor.
