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. There has been no investigation on the role of NLR and PLR in IPNB.
