PIT (Prognostic Index for PTCL-U)
Prognostic Index for PTCL-U (Gallamini 2004): age > 60, elevated LDH, ECOG ≥ 2, and bone-marrow involvement give a 0–4 score mapping to a prognostic group in peripheral T-cell lymphoma.

Example
- Age > 60 years
- Yes
- LDH above normal
- Yes
- ECOG performance status ≥ 2
- No
- Bone-marrow involvement
- No
Result: PIT 2 — prognostic group 3.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- 0-1
- Groups 1-2 (favorable).
- 2-4
- Groups 3-4 (unfavorable). One point each: age > 60, LDH > normal, ECOG >= 2, marrow. A prognostic index, not a treatment order.
What you enter
- Age > 60 years (+1)
- LDH above normal (+1)
- ECOG performance status ≥ 2 (+1)
- Bone-marrow involvement (+1)
