SII And PALBI is Associated With the Prognosis of Pancreatic Cancer Surgery(SII,PALBI)

The systemic immune-inflammation index(SII), based on the counts of platelets, neutrophils, and lymphocytes,was first found to be related to the prognosis of patients in melanoma12, and was subsequently confirmed in malignant tumors such as hepatocellular carcinoma13,and lung cancer12. A retrospective multicenter cohort study showed that bilirubin levels can interfere some inflammation index'prognosis of PDAC7.The platelet-albumin-bilirubin (platelet-albumin-bilirubin, PALBI) grade as a prognostic indicator of inflammation has been found in recent years, and its role has been confirmed in patients with liver cirrhosis14,15 and hepatocellular carcinoma 16, but there is no research to verify its role in patients with pancreatic cancer. This study aims to verify the predictive value of systemic immune inflammation index (SII) and platelet-albumin-bilirubin grade (PALBI) for the prognosis of patients with pancreatic cancer surgery, and to explore the significance of other inflammatory indicators in the overall survival(OS) and disease-free survival (DFS).
