Upper Urinary Tract Urothelial Carcinoma Diagnosis Effect on Life Expectancy Relative to Population-Based Controls: A Retrospective Analysis
Bibliographic record
Abstract
Introduction: The aim of the study was to examine 5-year overall survival (OS) of upper urinary tract urothelial carcinoma (UTUC) patients versus age- and sex-matched population-based controls. METHODS: Within Surveillance, Epidemiology, and End Results database (2004-2020), we identified newly diagnosed (2004-2015) UTUC patients. Relying on Social Security Administration Life Tables (2004-2020), age- and sex- matched population-based controls were simulated (Monte Carlo simulation). RESULTS: Of 10,140 UTUC patients, 3,984 (39%) exhibited localized, 4,904 (49%) locally advanced, and 1,252 (12%) metastatic stages. At 5 years of follow-up, the OS rate was 41 versus 78% (Δ 37%) in UTUC patients versus controls. According to stage, OS difference was greatest in metastatic stage (4 vs. 75%; Δ 71%), followed by locally advanced (36 vs. 78%; Δ 42%) and localized stages (58 vs. 78%; Δ 20%). At 5 years of follow-up, the CSM rate was 44%, and the OCM rate was 16%. According to stage, CSM and OCM rates were 88 and 7% in metastatic, 49 and 15% in locally advanced, and 22 and 19% in localized stage UTUC patients. CONCLUSION: UTUC patients may experience worse OS compared to population-based controls. The most pronounced differences in the 5-year OS were recorded in metastatic and locally advanced stages, suggesting a potentially substantial impact of UTUC on patients' life expectancy. .

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
