Lai C, Wu Z, Li Z, et al. - According to the results, this research uncovered the prognostic value of immune-related lncRNAs for bladder cancer and demonstrated that they may regulate tumor pathogenesis in various ways.

• Researchers recruited a total of 320 differentially expressed lncRNAs.

• Individuals were classified randomly into the training data set and the testing data set at a 2: 1 ratio.

• Nine immune-related lncRNAs with prognostic significance were distinguished in the training data set.

• They established a risk score model to categorize patients as high- and low-risk cohorts.

• Compared with those in the high-risk cohort, patients in the low-risk cohort had better survival outcomes.

• Based on the indicators including age, gender, tumor-node-metastases stage, and risk score, the nomogram was established.

• The receiver operating characteristic curve analysis, concordance index method, calibration curve, and decision curve analysis confirmed the model's predictive performance.

• Similar results were also achieved by the testing data set.

• As per the findings, bioinformatics analysis implied that the 9-lncRNA signature was involved in the modulation of various immune responses, antigen processing and presentation, and T cell receptor signaling pathway.
