CRP and neoplasm: Serological inflammatory markers—such as C-reactive protein (CRP), neutrophil-to-lymphocyte ratio (NLR), platelet-lymphocyte ratio (PLR), gamma-glutamyl transferase (GGT), and carbohydrate antigens (CA199, CA125)—reflect the host’s inflammatory and immune response, which plays a crucial role in tumor initiation, progression, and metastasis (McMillan, 2009; Guthrie et al., 2013; Templeton et al., 2014a; Liu et al., 2019; Zhang et al., 2019).
