Sokal / ELTS Risk Scores (CML)
Sokal index (1984) for chronic myeloid leukemia.
Open the calculator → Runs in your browser. Data leaves only if you deliberately send a problem report from the interactive tool.
Example
- Age
- 50 years
- Spleen size below costal margin
- 5 cm
- Platelet count
- 300 x10^9/L
- Peripheral blood blasts
- 2 %
Result: Sokal relative risk 0.91 (intermediate risk); ELTS 1.58 (intermediate risk).
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Sokal
- exp hazard over age, spleen, platelets and blasts -> low < 0.8, intermediate 0.8-1.2, high > 1.2.
- ELTS
- EUTOS long-term-survival score -> low <= 1.5680, intermediate <= 2.2185, high > 2.2185.
What you enter
- Age
- Spleen size below costal margin
- Platelet count
- Peripheral blood blasts
