A nomogram integrating mutation signatures and clinical features for prognostic stratification in bladder cancer.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
purposeBladder cancer (BLCA) is a typical malignancy in the urinary tract, with a dismal survival rate and limited therapeutic options. There is a growing demand for clinically relevant biomarkers to effectively stratify prognosis. This study aims to develop a prognostic model utilizing mutation signatures and clinical characteristics to inform the clinical management of BLCA.
methodsThe data of 631 BLCA patients were retrospectively reviewed, including 538 patients from The Cancer Genome Atlas (TCGA) and 93 patients from a Chinese cohort. Univariate and multivariate analyses were performed to identify the independent prognostic factors for overall survival (OS).
resultsMultivariate Cox regression analysis revealed that a 30-mutated gene signature and age were independent prognostic factors for BLCA. The prognostic nomogram was constructed to predict the probability of 1-, 3-, and 5-year OS, achieving area under the curve (AUC) values of 0.800, 0.749, and 0.731 in the training group, and 0.641, 0.820, and 0.759 in the validation group, respectively. Additionally, high risk scores were associated with poorer outcomes across all clinical subgroups. Patients with high-risk profiles exhibited higher neoantigen burden (p = 0.029), copy number variation (CNV) count (p = 0.013), and DNA damage response (DDR) mutations (p < 0.001) compared to those with low-risk profiles.
conclusionsThe model incorporating mutation signatures and clinical factors demonstrated accuracy in predicting changing cancer survival risk over time.This suggests that the model has the potential to serve as a valuable prognostic tool for BLCA.
