Punteggio di Leibovich (RCC)
cm
Clinical Context & Background
Il modello è destinato al carcinoma renale sporadico, unilaterale, a cellule chiare pT1-4 N0/+ M0 dopo nefrectomia. Utilizza TNM 2002 e grado nucleare di Fuhrman e non è il modello Leibovich 2018.
Riferimento: Leibovich BC et al. Cancer. 2003;97(7):1663-1671. DOI: 10.1002/cncr.11234.
Formula Logic
Punti per pT + pN + dimensione + grado di Fuhrman + necrosi.Reference Data
| Gruppo di rischio | Punteggio | MFS a 5 anni | MFS a 10 anni |
|---|---|---|---|
| Basso | 0-2 | 97,1% | 92,5% |
| Intermedio | 3-5 | 73,8% | 64,3% |
| Alto | ≥6 | 31,2% | 23,6% |

Verified: Production browser revalidation
- Three source-backed cases passed through visible production controls at Leibovich scores 0, 3, and 11.
- Low, Intermediate, and High groups rendered as expected.
- No unexpected N/A, literal undefined value, stale control, unsupported gauge, or browser-console error was observed.
Case-level evidence is retained in validation/browser-revalidation/leibovich-prognostic-rcc-2026-08-03.json.
: Production browser validation
- Ten source-backed cases were exercised on the public production route through visible browser controls; 10/10 case records passed their expected-versus-observed assertions across 11 visible submissions.
- Overall browser status: failed-console. medium: Production emitted minified React error #418 during route loads/reloads used by this run.
- Case-level inputs, expected and observed results, reset/repeat behavior, failure reproductions, and console evidence are retained in the production-browser evidence record.
Case-level production evidence is retained in validation/browser-production/leibovich-prognostic-rcc.json.
: Full validation test
- Passed 48/48 literal checks covering scores 0-11, every source category and boundary, and strict missing or invalid input behavior with zero difference.
: Correction
- Corrected pT4 to 4 points rather than 5.
- Corrected source-group 5-year metastasis-free survival estimates to 97.1%, 73.8%, and 31.2%, and added the 10-year estimates 92.5%, 64.3%, and 23.6%.
- Added a required positive numeric tumor-size input and rejected missing, extra, malformed, and out-of-domain inputs.
