There is a close relationship between inflammation and cancer.13 Increased levels of peripheral blood leukocytes, neutrophils, monocytes, neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), C-reactive protein (CRP), CRP-to-albumin ratio (CAR), and systemic immune-inflammation (SII) index have been associated with poor prognosis in patients with pancreatobiliary cancer, and the importance of inflammation in cancer biology has been emphasized.14-20. Here, CRP is linked to cancer.
