🧬 Prognostic Nutritional Index (Onodera PNI)
Assess nutritional/immune status with the Onodera Prognostic Nutritional Index.
Prognostic Nutritional Index (Onodera PNI)
Albumin (g/dL)
Total lymphocyte count (cells/µL)
When to use
Predict surgical and oncologic risk from albumin and lymphocytes.
How it works
PNI = 10 × albumin (g/dL) + 0.005 × lymphocyte count (/µL). Values below ~45 indicate higher risk.
Key points
- Lower PNI links to more complications and worse prognosis.
- Cut-offs vary by tumour and population.
- Easy to calculate from routine labs.
