PDCD1 and non-small cell lung carcinoma: Higher neutrophil-to-lymphocyte ratio (NLR) was associated with poor prognosis in advanced NSCLC patients receiving anti-PD-1 inhibitors (12), while higher NLR, higher platelet-to-lymphocyte ratio (PLR), and lower lymphocyte-to-monocyte ratio (LMR) at baseline were associated with poorer OS (13).
