Predictive utility of neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in intraductal papillary neoplasm of the bile duct.

Aim Of The Study: Intraductal papillary neoplasm of the bile duct (IPNB) can present at various stages of the disease. Each stage needs different treatment. The neutrophil-to-lymphocyte ratio (NLR) and the platelet-to-lymphocyte ratio (PLR) have been described as predictive markers for several tumors.
