What EORTC Bladder Cancer Recurrence and Progression Calculator does
The EORTC Bladder Cancer Recurrence and Progression Calculator estimates the probability of bladder cancer recurrence and progression over one and five years based on patient-specific factors. Users input six clinical parameters—number of tumors, tumor diameter, prior recurrence rate, disease stage, concomitant CIS, and tumor grade—to receive point scores and corresponding risk percentages. The output includes separate probabilities for recurrence and progression at both one-year and five-year intervals, providing a structured view of disease trajectory that can inform treatment discussions. The tool is designed for non-muscle invasive bladder cancer and presents results as calculated points and percentages rather than raw data, making the assessment accessible without requiring complex interpretation.
How to use the Omni Calculator EORTC Bladder Cancer Recurrence and Progression Calculator
- 1
Select the number of tumors present

Best for
Urologists, oncologists, and patients with non-muscle invasive bladder cancer who need a quick, evidence-based estimate of recurrence and progression risk to support treatment decisions.
Limitations
- Results are estimates based on published EORTC models and not a definitive diagnosis
- Requires accurate input of clinical data; user error can affect output
- Does not replace professional medical judgment or comprehensive patient evaluation
EORTC Bladder Cancer Recurrence and Progression Calculator FAQ
- How accurate is the EORTC Bladder Cancer Recurrence and Progression Calculator?
- The calculator uses validated EORTC scoring models to provide probability estimates based on six clinical parameters. It is a predictive tool derived from published research, but results should be interpreted as estimates rather than certainties and always discussed with a healthcare provider.
- Can this calculator be used for muscle-invasive bladder cancer?
- No, this tool is specifically designed for non-muscle invasive bladder cancer. Using it for other stages or types of bladder cancer would not provide accurate or relevant risk assessments.
- What do the recurrence and progression points represent?
- The points are calculated based on each input parameter and contribute to a total score that maps to one-year and five-year recurrence or progression probabilities. Higher point totals correspond to higher estimated risk percentages.
- Is the calculator suitable for follow-up monitoring after treatment?
- The tool can be used to estimate recurrence and progression risk based on current tumor characteristics, but it is not a substitute for regular clinical follow-up, imaging, or cystoscopy recommended by a urologist.
