The Role of Log Odds of Positive Lymph Nodes in Predicting the Survival after Resection for Ampullary Adenocarcinoma

Lymph node metastasis is a important factor on survival in ampullary adenocarcinoma. Log odds of positive lymph nodes (LODDS) is a novel prognostic indicator on lymph node status. We aimed to evaluate the prognostic impact of LODDS for the patients with ampullary adenocarcinoma who underwent R0 pancreaticoduodenectomy. The study includes 42 patients.. LODDS was calculated as “log (number of metastatic lymph nodes+0.5)/(number of total harvested...
