Abstract

fetched live from OpenAlex

OBJECTIVES: To investigate the relationship between chronic kidney disease and primary non-muscle-invasive bladder cancer. METHODS: Disease outcomes were analyzed in 418 patients treated with transurethral resection for primary non-muscle-invasive bladder cancer, and were correlated to traditional risk factors as well as chronic kidney disease stage according to estimated glomerular filtration rate: ≥60 (G1-2), 45-59 (G3a) or <45 (G3b-5). RESULTS: The median follow-up time was 40.0 months. There were 287 (68.7%), 98 (23.4%), and 33 (7.9%) patients with G1-2, G3a and G3b-5 chronic kidney disease, respectively. T1 tumor was present in 29.6% of G1-2, 43.9% of G3a and 51.4% of G3b-5 chronic kidney disease (P = 0.004). The proportion of histological grade 3 non-muscle-invasive bladder cancer was higher in G3a and G3b-5 than G1-2 (P < 0.001). Higher chronic kidney disease stage was associated with worse recurrence-free (P < 0.001) and progression-free survival (P = 0.017). In multivariable analysis, G3b-5 was found to be an independent predictor for recurrence (hazard ratio 1.87; P = 0.004) and progression (hazard ratio 2.96; P = 0.019). Chronic kidney disease stage was also strongly associated with the European Association of Urology bladder cancer risk groups (P < 0.001), and with shorter time to recurrence and progression in each group. CONCLUSIONS: Chronic kidney disease predicts the clinical outcome of primary non-muscle-invasive bladder cancer. Adding chronic kidney disease to the conventional risk factors might increase the accuracy of risk stratification.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human 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.
