Table 1 Inflammation-based prognostic scores
Scoring system | Score |
|---|---|
Neutrophil–lymphocyte ratio (NLR) | |
Neutrophil count: lymphocyte count ≥ 5 | 1 |
Neutrophil count: lymphocyte count < 5 | 0 |
Derived neutrophil–lymphocyte ratio (dNLR) | |
Neutrophil count: (leucocyte count–neutrophil count) ≥ 3 | 1 |
Neutrophil count: (leucocyte count–neutrophil count) < 3 | 0 |
Lymphocyte–monocyte ratio (LMR) | |
Lymphocyte count: monocyte count < 2.35 | 1 |
Lymphocyte count: monocyte count ≥ 2.35 | 0 |
Platelet–lymphocyte ratio (PLR) | |
Platelet count: lymphocyte count > 300 | 2 |
Platelet count: lymphocyte count 150–300 | 1 |
Platelet count: lymphocyte count < 150 | 0 |
Combination of platelet count and NLR (COP–NLR) | |
NLR > 3 and platelet count > 300 × 109/L | 2 |
NLR > 3 or platelet count > 300 × 109/L | 1 |
Neither NLR > 3 nor platelet count > 300 × 109/L | 0 |
Prognostic nutritional index (PNI) | |
Albumin (g/L) + 5 × total lymphocyte count (× 109/L) < 45 | 1 |
Albumin (g/L) + 5 × total lymphocyte count (× 109/L) ≥ 45 | 0 |
