Sokal Score for Chronic Myelogenous Leukemia (CML)

Calculates the Sokal prognostic score for CML using age, spleen size, platelet count, and blast percentage. Formula: exp(0.0116×(age−43.4) + 0.0345×(spleen−7.51) + 0.188×((platelet/700)²−0.563) + 0.0887×(blasts−2.10)). Low <0.8, Intermediate 0.8–1.2, High >1.2.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Calculates the Sokal prognostic score for CML using age, spleen size, platelet count, and blast percentage. Formula: exp(0.0116×(age−43.4) + 0.0345×(spleen−7.51) + 0.188×((platelet/700)²−0.563) + 0.0887×(blasts−2.10)). Low <0.8, Intermediate 0.8–1.2, High >1.2

Each component has a specific meaning:

  • Age — The age recorded for the scenario being assessed.
  • Spleen size — The spleen size recorded for the scenario being assessed.
  • Platelet count — The platelet count recorded for the scenario being assessed.
  • Blast percentage — The blast percentage recorded for the scenario being assessed.

Note: Interpret the sokal cml score result against the thresholds and context described above.

How to Use

Enter the age, spleen size, platelet count, blast percentage for the scenario you are assessing. Calculates the Sokal prognostic score for CML using age, spleen size, platelet count, and blast percentage. Formula: exp(0.0116×(age−43.4) + 0.0345×(spleen−7.51) + 0.188×((platelet/700)²−0.563) + 0.0887×(blasts−2.10)). Low <0.8, Intermediate 0.8–1.2, High >1.2.
