In conclusion, we identified three ITGs (ITGA7, ITGA5 and ITGB6) with prognostic value, constituting a new (ITGs-related) prognostic marker for BLCA prognostic model, and preliminarily explored the potential molecular mechanisms of this model, providing potential targets for BLCA prognosis. This evidence concerns the gene ITGA5 and bladder transitional cell carcinoma.
