(2020) found that blood inflammatory markers, such as the Derived Neutrophil-to-Lymphocyte Ratio (dNLR), Platelet-to-Lymphocyte Ratio (PLR), and C-reactive Protein (CRP), correlated with PFS and OS in Non-Small Cell Lung Cancer (NSCLC) patients undergoing immunotherapy or chemotherapy. Here, CRP is linked to non-small cell lung carcinoma.
