What it calculates

The “DLBCL Prognosis” calculator computes IPI score (0-5) from 7 parameters: age (years), ann arbor stage (1–4), ecog, ldh (U/L), ldh upper limit of normal (U/L), extranodal sites, bone marrow, cns, liver/gi tract or lung involvement (1 = yes).

Used by professionals and patients to assess health metrics, dosages, and risks.

Example calculation

With parameters Age = 65 years, Ann Arbor stage (1–4) = 3, ECOG = 1, LDH = 300 U/L, LDH upper limit of normal = 250 U/L, Extranodal sites = 1, Bone marrow, CNS, liver/GI tract or lung involvement (1 = yes) = 0 the result is 3 (A prognostic estimate; does not replace the oncologist's judgment).

How to use

  1. Enter age, ann arbor stage (1–4), ecog, ldh, ldh upper limit of normal, extranodal sites and bone marrow, cns, liver/gi tract or lung involvement (1 = yes) — each field above is adjustable with a slider.
  2. IPI score (0-5) is calculated automatically as you type.
  3. Check the worked example below to see the formula applied to real numbers.

FAQ

How is BMI calculated?
BMI = weight (kg) / height (m)². Example: 70 kg / (1.75 m)² = 22.9. The WHO normal range is 18.5–24.9; below that is underweight, 25–29.9 is overweight, and 30+ is obese.
Is BMI accurate for everyone?
No. BMI does not distinguish muscle from fat, so athletes may show a high BMI with low body fat. It is also less reliable for teenagers, pregnant people, older adults, and very tall or short individuals.
What are the BMI categories?
Underweight: below 18.5. Normal: 18.5–24.9. Overweight: 25–29.9. Obese class I: 30–34.9; class II: 35–39.9; class III: 40+.
What is a better measure than BMI?
Body fat percentage, waist-to-height ratio (aim for under 0.5), and waist circumference give a clearer picture of health than BMI alone.
