Example
- Age >= 70 years
- Yes
- Elevated LDH
- Yes
Result: MALT-IPI 2 of 3 — high risk (5-year EFS about 29%).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Groups
- 0 low (5-yr EFS ~70%), 1 intermediate (~56%), >= 2 high (~29%).
What you enter
- Age >= 70 years
- Ann Arbor stage III or IV
- Elevated LDH (above upper limit of normal)
How this is calculated
- Factors
- age >= 70, Ann Arbor stage III/IV, elevated LDH (>ULN) - one point each = 0-3.
