More about: EORTC Bladder Cancer Risk

What it calculates

The “EORTC Bladder Cancer Risk” calculator computes Recurrence risk score (EORTC) from 6 parameters: number of tumors, diameter of largest tumor (cm), prior recurrence rate (0 = primary, 1 = ≤1 per year, 2 = >1 per year), stage t1 (1 = yes, 0 = ta), concurrent cis (1 = yes), who 1973 grade g (1–3).

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

Example calculation

With parameters Number of tumors = 3, Diameter of largest tumor = 3.5 cm, Prior recurrence rate (0 = primary, 1 = ≤1 per year, 2 = >1 per year) = 0, Stage T1 (1 = yes, 0 = Ta) = 1, Concurrent CIS (1 = yes) = 0, WHO 1973 grade G (1–3) = 3 the result is 9 (For non-muscle-invasive bladder cancer; treatment decisions are made by a urologist).

How to use

  1. Enter number of tumors, diameter of largest tumor, prior recurrence rate (0 = primary, 1 = ≤1 per year, 2 = >1 per year), stage t1 (1 = yes, 0 = ta), concurrent cis (1 = yes) and who 1973 grade g (1–3) — each field above is adjustable with a slider.
  2. Recurrence risk score (EORTC) is calculated automatically as you type.
  3. Check the worked example below to see the formula applied to real numbers.
  4. Copy the result or bookmark this calculator.

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.
