“…Of interest is the role of inflammation, which is postulated to be influential in tumor progression and metastasis ( Singh et al, 2019 ). Recent studies have confirmed that various markers of the systemic inflammatory response, for example, the C-reactive Protein (CRP), Platelet to Lymphocyte Ratio (PLR), Lymphocyte to Monocyte Ratio (LMR), and Neutrophil to Lymphocyte Ratio (NLR), all correlate to the prognosis of a myriad of tumors such as high-grade glioma ( He et al, 2021b ), colorectal cancer ( Dagmura et al, 2021 ), head and neck cancer ( Saroul et al, 2021 ), oral squamous cell cancer ( Yamagata et al, 2021 ), and gastric cancer ( Liu et al, 2021 ). The latest evidence also suggests that a similar tumor-inflammation relationship exists for breast cancer, indicating that quantifying the inflammatory response may be useful in treating and prognosticating breast cancer ( Dong et al, 2021 ).…”
