Diagnostic Accuracy of Procalcitonin, Neutrophil-to-Lymphocyte Ratio, and C-Reactive Protein in Detection of Bacterial Infections and Prediction of Outcome in Nonneutropenic Febrile Patients with Lung Malignancy

Figure 2

Inflammatory markers (PCT, CRP, WBC, NEU, and NLR) between bacteria-infected subgroup A (N = 69) and TF subgroup A (N = 56) in febrile NNLCPs. The differences of PCT (a), CRP (b), WBC (c) and NEU (d) levels, and NLR (e) between bacteria-infected subgroup A (N = 69) and TF subgroup A (N = 56). The horizontal lines represented the median. Statistical significance was calculated with Mann–Whitney test. (f) ROC curves analysis for PCT, CRP, WBC, NEU, and NLR in subgroup A of NNLCPs. ; PCT: procalcitonin; CRP: C-reactive protein; WBC: white blood cell; NEU: neutrophil; NLR: neutrophil-to-lymphocyte ratio; TF: tumor fever; AUC: area under the ROC curve; NNLCPs: nonneutropenic lung cancer patients.
