GRIm-Score (Gustave Roussy Immune Score)

GRIm-Score (Bigot 2017): serum albumin, neutrophil-to-lymphocyte ratio, and elevated LDH give a 0–3 score where a higher total marks worse survival on immunotherapy.

Example

Serum albumin
3.0 g/dL
Neutrophil-to-lymphocyte ratio
8
LDH above the upper limit of normal
Yes

Result: GRIm-Score 3 — high risk (2-3): worse survival on immunotherapy.

The tool opens with these values already filled in. Replace them with your own.

What the result means

0-1
Low risk.
2-3
High risk: worse overall survival on immune-checkpoint therapy. One point each: LDH > ULN, albumin < 3.5, NLR > 6. Not a treatment order.

What you enter

  • Serum albumin
  • Neutrophil-to-lymphocyte ratio
  • LDH above the upper limit of normal
