Abe T, et al. - The prognostic role of the neutrophil-to-lymphocyte ratio (NLR) and the relationship between the NLR and TNM stage in pancreatic ductal adenocarcinoma (PDAC) patients following curative resection were investigated. Researchers noted that for early TNM stage PDAC, an elevated preoperative NLR was an important prognosticator. The NLR can be calculated using inexpensive and readily available biomarkers and can be observed as a novel tool for predicting long-term survival in patients, especially those with early stage PDAC.
