How this service works
Hasford 2011 EUTOS score for baseline untreated chronic myeloid leukemia (CML). eutos_score = 4 * spleen_cm + 7 * basophils_percent, rounded to 1 decimal. Low if score ≤ 87; high if score > 87. spleen_cm is centimetres below the costal margin (0-40); basophils_percent is peripheral-blood basophils (0-100). Not a CML diagnosis and not a TKI choice.
Output
Returns the computed EUTOS score (4 × spleen_cm + 7 × basophils_percent, rounded to 1 decimal) and a risk classification: 'low' if the score is ≤87 or 'high' if the score is >87.
Example use cases
CML baseline risk stratification
“My patient has newly diagnosed untreated CML. Their spleen is 12 cm below the costal margin and their basophil count is 6% of leukocytes. What is their EUTOS score and are they low or high risk?”
Pre-treatment prognostic documentation
“Before starting TKI therapy, I need to document the EUTOS score for this CML patient — spleen is 3 cm below the costal margin and basophils are 2%. Can you compute it?”
Clinical trial eligibility check
“For a clinical trial enrollment, I need the EUTOS score for a baseline untreated CML patient with a spleen size of 20 cm below the costal margin and 10% peripheral basophils — what's the score and risk class?”

Endpoint
GEThttps://api.magentlab.com/api/calc/eutosWhen to prefer
Use this endpoint when you need a fast, reliable server-side computation of the Hasford 2011 EUTOS score for a baseline untreated CML patient, especially in automated clinical workflows or agent pipelines where you want an authoritative risk classification without implementing the formula locally. Prefer it over manual calculation to avoid arithmetic errors and to get a structured, machine-readable response.
Side effects
- Missing required query parameter spleen_cm or basophils_percent returns an error
- Values outside the valid range (spleen_cm 0–40, basophils_percent 0–100) may return a validation error
- Non-numeric inputs for parameters cause a bad request response
- Payment not completed (x402) results in payment-required error before computation
