PD-L1 Expression in Muscle Invasive Urothelial Carcinomas as Assessed via Immunohistochemistry: Correlations with Specific Clinical and Pathological Features, with Emphasis on Prognosis after Radical Cystectomy.

PD-L1-positive staining was associated with improved OS compared to PD-L1-negative cases, although the difference did not reach statistical significance ( p = 0.366): 28 months (95% CI: 0–58.6) versus 12 months (95% CI: 3.98–20) ( Figure 2 ).
