The EUTOS Score for CML Calculation Formula

Behold the magical formula, and don’t let its simplicity bewitch you! It’s a key that unlocks profound insights into CML.

EUTOS score = (7 * percentage of basophils) + (4 * spleen size)

EUTOS Score Categories

Score Interpretation
0-87 Low Risk
88-148 Intermediate Risk
149 and above High Risk

Calculation Examples

Individual Basophils (%) Spleen Size Calculation EUTOS Score
John Doe 10 15 (7 * 10) + (4 * 15) = 130 130
Jane Doe 5 20 (7 * 5) + (4 * 20) = 95 95

  1. What is the EUTOS Score for CML? The EUTOS Score is a calculation used to predict the prognosis of patients with chronic myeloid leukemia (CML).
  2. How is the EUTOS Score calculated? The EUTOS Score is calculated by multiplying the percentage of basophils by 7 and adding that to the product of spleen size and 4.
  3. What does a high EUTOS Score indicate? A high EUTOS Score indicates a high risk prognosis for patients with CML.
  4. What is the range of the EUTOS Score? The EUTOS Score can range from 0 to any number, depending on the values of basophils and spleen size.
  5. Can the EUTOS Score change over time? Yes, the EUTOS Score can change over time based on the changes in the percentage of basophils and spleen size.
  6. Who developed the EUTOS Score? The EUTOS Score was developed by researchers to help predict the prognosis of patients with CML.
  7. Is the EUTOS Score accurate? The EUTOS Score has a moderate to high level of accuracy, depending on the calculation method used.
  8. What is the difference between the Original and the Longitudinal EUTOS Score? The Original EUTOS Score is easier to calculate but less precise, while the Longitudinal EUTOS Score is more complex but accurate.
  9. What are the limitations of the EUTOS Score? The EUTOS Score has limited precision and its accuracy depends on accurate basophil counts and spleen size measurements.
  10. What are some alternative methods to the EUTOS Score? Some alternative methods include the Sokal Score and the Euro Score.
