EORTC Risk Tables (NMIBC)
Clinical Context & Background
The EORTC risk tables predict the probability of recurrence and progression to muscle-invasive disease in NMIBC patients. It is based on a combined score of 6 factors: Number of tumors, Tumor size, Prior recurrence rate, T-category, CIS, and Grade. Note: These tables often overestimate risk in BCG-treated patients (see CUETO model).
Formula Logic
Sum of points for Recurrence and Progression separately.Reference Data
| Score (Rec / Prog) | 1-Year Risk | 5-Year Risk |
|---|---|---|
| Recurrence 0 | 15% | 31% |
| Recurrence 1-4 | 24% | 46% |
| Recurrence 5-9 | 38% | 62% |
| Recurrence 10-17 | 61% | 78% |
| Progression 0 | 0.2% | 0.8% |
| Progression 2-6 | 1% | 6% |
| Progression 7-13 | 5% | 17% |
| Progression 14-23 | 17% | 45% |
