Leibovich-Score-Rechner - Nierenzellkarzinom
cm
Clinical Context & Background
Das Modell gilt für sporadisches, unilaterales pT1-4 N0/+ M0 klarzelliges Nierenzellkarzinom nach Nephrektomie. Es verwendet TNM 2002 und den Fuhrman-Kerngrad und ist nicht das Leibovich-Modell 2018.

Calculation verification history
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.
