C-reactive protein (CRP), albumin, neutrophil, lymphocyte, platelet, and combined formulations of these values include the neutrophil to lymphocyte ratio (NLR), lymphocyte to monocyte ratio (LMR), platelet to lymphocyte ratio (PLR), lymphocyte to C-reactive protein ratio (LCR), systemic inflammation score (SIS), and Prognostic Nutrition Index (PNI), and the prognostic value and importance of these markers have been tried to be understood through various studies, and studies on these markers in many types of cancer are still continuing at full speed [4–6]. The gene discussed is CRP; the disease is cancer.
