Example

Karnofsky < 80%
Yes
LDH > 1.5× ULN
Yes

Result: MSKCC: 2 factors — intermediate risk (median OS 10 mo).

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

What the result means

Groups
Favorable 0, intermediate 1–2, poor ≥ 3; the historical comparator to the modern IMDC model.

What you enter

  • Karnofsky < 80%
  • LDH > 1.5× ULN
  • Hemoglobin < LLN
  • Corrected calcium > 10 mg/dL
  • Diagnosis to treatment < 1 year
How this is calculated
Factors
Karnofsky < 80%, LDH > 1.5× ULN, low hemoglobin, high corrected calcium, dx-to-treatment < 1 y (1 point each).
