Regarding preoperative blood results the cancer patients and especially PDAC (PER+) show lower hemoglobin levels (PDAC (PER+) 10.8 g/dl vs. NC 14.2 g/dl) (p = 0.021), higher CRP (p = 0.01), bilirubin (p = 0.008) and gamma-glutamyl transferase (ɤGT) levels (p = 0.02). This evidence concerns the gene CRP and cancer.
