Nomogram incorporating prognostic immune-inflammatory-nutritional score for survival prediction in pancreatic cancer: A retrospective study

Prognosis prediction for pancreatic cancer has always been difficult in clinical practice because of its high heterogeneity and mortality. The aim of the study was to assess the value of prognostic immune-inflammatorynutritional (PIIN) score on overall survival (OS) in postoperative patients with pancreatic cancer and to develop a nomogram incorporating PIIN score.
