Historical MSKCC Pancreatic Adenocarcinoma Nomogram (Retired)
Retired reference page for the 2004 Brennan et al. postoperative pancreatic adenocarcinoma nomogram. OncoToolkit does not reproduce or calculate this model because its former point-sum proxy was not the published nomogram and no current official MSK executable implementation could be verified.
No calculation is available
No calculation was performed. This permanent route is retained only as a historical reference to Brennan et al. (2004).
Why the former tool was retired
The publication describes a multivariable Cox graphical nomogram. It does not publish the former OncoToolkit additive weights, risk bands, median-survival ranges, or generated factor conclusions. Those unsupported behaviors, their defaults, and treatment-planning language were removed rather than presented as a reconstruction.
Historical source facts
- 555 single-institution resections for pancreatic adenocarcinoma from October 1983 through April 2000.
- Historical 1-, 2-, and 3-year disease-specific survival after initial resection, conditional on no competing death.
- Cox graphical nomogram with bootstrap-corrected concordance index 0.64.
Current public-tool review
The public MSK Prediction Tools directory was reviewed on 2026-07-24. No current publicly accessible official pancreatic calculator or report schema could be verified. This limited finding does not establish whether MSK retains any internal or nonpublic implementation.
Sources
This page does not calculate a score, survival estimate, prognosis, treatment benefit, or treatment recommendation. The Callery Fistula Risk Score addresses a different postoperative complication endpoint and is not presented as a substitute.

Calculation verification history
Verified retirement: 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 0 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/mskcc-pancreas.json.
: Historical source reconciled
- Locked identity to Brennan et al. 2004 postresection 1-, 2-, and 3-year disease-specific survival nomogram from 555 MSK patients.
- Recorded the Cox graphical-model design, competing-death condition, historical cohort dates, and bootstrap-corrected c-index without reconstructing the nomogram.
: Unsupported proxy retired
- Removed point sum, risk bands, median-survival claims, defaults, inputs, and treatment-planning language because they did not reproduce the publication.
- No historical reconstruction or external-result recorder was substituted.
: Permanent reference route verified
- Preserved the permanent URL as a non-calculating historical reference and verified fail-closed behavior, source wording, catalog parity, sitemap retention, and retirement UI.
- Passed 320 deterministic assertions. This verifies retirement implementation and history, not the historical nomogram's clinical performance.
Verified retirement implementation; not prospective or independent clinical validation.
Verification confirms the fail-closed retirement behavior, permanent reference route, source wording, and history. It does not reproduce or clinically validate the historical nomogram.
