Inflammation-based prognostic scores, including the Glasgow Prognostic Score (GPS; based on serum CRP and albumin levels), neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR), Prognostic Nutritional Index (PNI; based on albumin and lymphocyte counts), and Prognostic Index (PI; based on serum CRP and white blood cell counts), are well-known prognostic biomarkers for several types of cancer [18]. Here, CRP is linked to cancer.
